Indian Journal of Otology 2018 24(4):214-218
Background: Chronic Suppurative Otitis Media (CSOM) is a disease well known for its persistence and recurrence, inspite of giving treatment. The microbiology cultures show the growth of a lot of organisms, frequently multiple and these differ based on patient population, climate, and whether or not antibiotics have been recently used. Objectives: To identify the commonest causative organism of CSOM in a government hospital of northern India and identify the sensitivity to antibiotics so as to achieve early dry ear for surgical intervention. Methodology: This study was done, from March 2018 to September 2018 on 100 patients with complaints of ear discharge. Pus samples were collected from the discharging ears, subjected to culture and sensitivity and the organisms isolated were identified by morphological, cultural and biochemical characteristics. Results: Most common organism causing CSOM in our study Staphylococcus aureus, followed by Pseudomonas aeruginosa. Most patients with Staphylococcus infection were sensitive to Vancomycin followed by Linezolid and Gentamycin whereas patients with Pseudomonas aeruginosa were sensitive to Amikacin and Ciprofloxacin. Conclusion: Early and effective intervention using appropriate topical as well as systemic antibiotics can decrease the chronicity of CSOM and prevent long term complications.

Objective: The objective of the study was to evaluate early auditory and verbal outcomes following cochlear implant (CI) in patients with radiological findings suggestive of demyelinating lesions in the brain. Methods: The study was conducted in the Department of ENT, Civil Hospital, Ahmedabad, Gujarat. We studied and evaluated early auditory and verbal outcome following CI in 30 patients who had demyelinating lesions in the brain on magnetic resonance imaging, of 1- to 5-year age group. Hearing and speech ability was recorded on categories of auditory performance (CAP) scale and speech intelligibility rating scale and was compared to patients with normal cerebral myelination. Results: Patients in case group showed comparable scores on CAP scale and speech intelligibility scale compared to the patients who did not have demyelinating disease in the same time frame. Conclusion: Patients with demyelinating lesions showed similar auditory and verbal responses compared to normal implant patients who show that demyelinating diseases do not pose limitations in the early outcome of auditory response in such patients.

Introduction: Chronic suppurative otitis media (CSOM) is a major health problem throughout the world in underdeveloped and developing countries including India. The high prevalence of CSOM in school children in India has led us to undertake this study in schoolgoing children of rural and urban areas of Muzaffarnagar, Uttar Pradesh and to find out the various predisposing factors for the development of CSOM. Objectives: The objective is to find out the prevalence of CSOM in schoolgoing children of the rural and urban population about age, sex, and socioeconomic status. Materials and Methods: Students were randomly selected from primary schools in rural and urban areas of Muzaffarnagar, Uttar Pradesh. Cases selected was categorized in relation to age, sex, socioeconomic status, and prevalence of the safe and unsafe type of CSOM. Observations: In the present study, a cross-sectional survey was conducted in 2158 school children between the age group of 5 and 15 years. A total of 1161 children belonged to urban school whereas 997 children were from three adjacent rural government schools. A total of 78 children were found to be suffering from either unilateral or bilateral CSOM. Conclusion: The prevalence of CSOM in urban school children was 2.32%, while for rural children, it was 5.11%. 42.10% of cases of CSOM belonged to upper-lower socioeconomic group followed by lower middle group (31.57%). The tubotympanic disease was present in 87.18% of CSOM cases while 12.82% had atticoantral disease. Active CSOM was found amongst 37.18% while 62.82% had inactive disease. 42.10% had smoking father, 36.84% had indoor cooking with kerosene oil exposure, and 34.21% used unhygienic ear cleaning methods. 31.58% had a history of recurrent URI, 28.95% had chronic tonsillitis, and 21.05% of children had domain name system as associated findings with CSOM.

Objective: The aim of this study is to determine the efficacy of vestibular rehabilitation (VR) exercise of patients with uncompensated unilateral peripheral vestibular dysfunction. Materials and Methods: An intervention study was conducted on 20 patients their age ranging from 20 to 60 years. The main complaint of the participants was chronic dizziness (dizziness for >3 months). Dizzy patients were recruited from the Ear, Nose, and Throat department. The study was conducted in the audiovestibular unit. All participants in the study were subjected to basic audiological evaluation and vestibular evaluation (videonystagmography). The Dizziness handicap inventory questionnaire (DHI) was carried out twice (pre and post) rehabilitation program. The VR therapy was performed according to the protocol established by Cawthorne and Cooksey and Norre exercises. Results: All the DHI scores reduced significantly after VR. There were no differences among genders; adults and elderly patients. Conclusion: The result of this study proved the importance and the efficacy of VR. It considered a useful therapeutic approach for improvement in the quality of life of individuals with unilateral peripheral vestibular weakness. The improvement was not influenced by sex, age, or duration of disease. It considered a low-cost, short, and safe treatment technique which can be widely used in outpatients without the need for sophisticated tools.

Objective: This study aimed to investigate the effect of N-acetylcysteine (NAC) on cochlear function in patients with chronic kidney disease (CKD). Methodology: The statistical population of this controlled clinical trial included all CKD patients. In total, 64 samples, selected from patients visiting the Dialysis Center of Al-Zahra Hospital from February 2017 to May 2017, were equally randomized into the intervention and control groups. At the baseline, the pure-tone audiometry (PTA) and Distortion Product Oto Acoustic Emissions (DP-OAE) tests were conducted. Then, NAC was administered in the intervention group for 8 weeks. Aforementioned hearing tests were repeated at the end of the interventions and results were compared. Finally, data analysis was carried out in SPSS. Results: Based on the mean scores of hearing threshold, there was no significant between-group difference in the speech discrimination score (SDS) speech reception threshold (SRT) of the left and right sides following NAC administration (P > 0.05). Comparison of the mean OAE following NAC administration showed a significant between-group difference, based on the mean signal/noise ratios (S/N 1000, 2000, and 4000) of the both right and left ears (P < 0.05). To compare the mean DP-OAE changes before and after the intervention between the two groups, the difference between pre- and post-intervention DP-OAE variables was first computed. Then, these changes were compared. A significant between-group difference was observed in S/N ratios of 1000, 2000, and 4000 Hz of the both right and left sides before and after the intervention (P < 0.05). In contrast, changes in other variables did not imply a significant between-group difference (P > 0.05). Conclusion: This study showed the effectiveness of NAC in improving cochlear function in 1, 2, and 4 KHz; whereas, it did not significantly affect the hearing threshold.

Indian Journal of Otology 2018 24(4):242-245
Introduction: In general, voice therapy is given on one-to-one basis where each individual is provided therapy by the clinician individually. On the other hand, in group therapy, the treatment is provided to a group of individuals with a similar disorder. Need of the Study: There was a need to conduct this study as there are very few studies on finding the efficacy of group therapy for hyperfunctional voice disorder among teachers especially in India. Aim: The primary aim of the study was to find out the efficacy of group voice therapy in hyperfunctional voice disorders among teachers. The secondary aim was to compare the outcome of group therapy and individual therapy in hyperfunctional voice disorder among teachers. Methodology: Totally 16 individuals in the age range between 25 and 45 years who were teachers by profession with hyperfunctional voice disorder were enrolled in the study. Two age and gender-matched groups were constituted. Group A consisted of eight (6 males and 2 females) individuals with a mean age of 35.6 years. Group B was comprised of eight (6 males and 2 females) with a mean age of 34 years. Group A was enrolled into group therapy while Group B was enrolled into individual voice therapy. The participants underwent a clinical voice evaluation including auditory-perceptual and quality of life assessment using Grade, Roughness, Breathiness, Asthenia, Strain scale, Dr. Speech software and Voice Handicap Inventory. Voice therapy protocol included 12 sessions once a week. It consisted of 15 min. of indirect and the rest 45 min. of Lessac-Madsen Resonant voice Therapy. Posttherapy measures were taken for both the groups. Results and Discussion: Results showed significant improvement post voice therapy in acoustic analysis measures, i.e. jitter and shimmer in both the groups. In perceptual measures, there was a significant improvement in Grade, Roughness, and Strain measures in both the groups while in quality of life measures there was significant improvement post-therapy in both the groups. When compared between groups A and B there was no significant difference in all the measures in both pre- and post-therapy assessments. Our study has recruited the control group and found there was no significant difference between the individual versus group voice therapy. Conclusion: Group voice therapy is as effective in the treatment of hyperfunctional voice disorders as individual therapy. There is a need to get data on a larger population to generalize the findings.

Introduction: Hearing loss in early life hampers development of children, early detection of hearing loss in paediatric age group gives opportunity to treat it and good speech and overall development of children. In this study BERA was done on high risk children and various risk factor compared. Comparison between BERA and OAE was done as a screening test. Aims: To evaluate the hearing threshold and find the incidence of deafness in high risk paediatric age group category and analyse the common risk factors and to compare BERA with OAE.Materials and Method: 60 infants and high risk children were subjected to BERA after detailed ENT examination. In 0 to 5 year age group dPOAE was done on same sitting. Results analysed. Statistical Analysis Used: Relative risk ratio was done for each risk factor. Sensitivity and specificity of OAE in comparison to BERA as a gold standard was done. Results: In this study 42% of high risk children showed hearing loss. Most common risk factor among children with hearing loss was consanguineous marriage (24%) followed by neonatal jaundice (16%), low birth weight (12%) and others. Comparison of OAE and BERA with BERA as gold standard test shows sensitivity of OAE is 96.15%, specificity is 72.73%. Conclusion: All high risk children should be screened with BERA early so that children with hearing loss identified and taken care for that. In centre where no experts available OAE can be used for screening of high risk children as OAE has a good sensitivity.

Aim: A new generation of bone-anchored hearing aid, Baha® 4 Attract System has been introduced as a single-stage procedure with the magnet and abutment implanted on the skull with complete skin cover. Aim is to discuss the surgical and audiological outcome of this new device. Materials and Methods: This was a prospective study. There were 34 patients who fulfilled criteria for bone conduction hearing aid. Out of these patients, 27 were unwilling for the surgical procedure. Prior to the surgery, a trial with a soft band was carried out and seven patients were satisfied with the trial. The outcomes were measured in the form of free-field pure-tone audiometry (PTA) after 3 months of surgery and quality of life gain using Speech, Spatial and Quality of hearing scale (SSQ-12B) questionnaire. Results: Outcomes in terms of gain in free-field PTA were good in all the seven patients. An average gain of 37.85 dB was observed. There was an improvement in quality of life as assessed by SSQ 12B questionnaire. An average score of 40.25 was achieved. Conclusion: Transcutaneous bone conduction aids are fast emerging as a viable alternate to traditional devices. These devices provide almost similar functional gain in hearing along with better cosmetic results, less complications, and minimal wound care.

Rheumatoid arthritis (RA) is therapeutically challenging due to patient heterogeneity and variability. Herein we describe a novel integration of RA synovial genome-scale transcriptomic profiling of different patient cohorts that can be used to provide predictive insights on drug responses. A normalized compendium consisting of 256 RA synovial samples that cover an intersection of 11,769 genes from 11 datasets was build and compared with similar datasets derived from OA patients and healthy controls. Differentially expression genes (DEGs) that were identified in three independent methods were fed into functional network analysis, with subsequent grouping of the samples based on a non-negative matrix factorization method. RA-relevant pathway activation scores and four machine learning classification techniques supported the generation of a predictive model of patient treatment response. We identified 876 up-regulated DEGs including 24 known genetic risk factors and 8 drug targets. DEG-based subgrouping revealed 3 distinct RA patient clusters with distinct activity signatures for RA-relevant pathways. In the case of infliximab, we constructed a classifier of drug response that was highly accurate with an AUC/AUPR of 0.92/0.86. The most informative pathways in achieving this performance were the NFκB-, FcεRI- TCR-, and TNF signaling pathways. Similarly, the expression of the HMMR, PRPF4B, EVI2A, RAB27A, MALT1, SNX6, and IFIH1 genes contributed in predicting the patient outcome. Construction and analysis of normalized synovial transcriptomic compendia can provide useful insights for understanding RA-related pathway involvement and drug responses for individual patients.

The incidence of Salmonella enterica serovar Paratyphi A (PA) infection is on the rise and no licensed vaccines are available. We evaluated cell mediated immune (CMI) responses elicited in volunteers following immunization with a single dose (109 or 1010 cfu) of a novel attenuated live oral PA-vaccine strain (CVD 1902). Results showed increases in PA-lipopolysaccharide-specific IgG- and/or IgA B-memory cells and production of IFN-γ, TNF-α, IL-10, IL-23 and RANTES following stimulation with PA-antigens by peripheral blood mononuclear cells obtained 28 days post immunization. Flow cytometry assays revealed that vaccine elicited PA-specific CD8+ and/or CD4+ T effector/memory cells were predominantly multifunctional concomitantly expressing CD107a and/or producing IFN-γ, TNF-α and/or IL-2. Similar proportions of these MF cells expressed, or not, the gut homing marker integrin α4β7. The results suggest that immunization with CVD 1902 elicits CMI responses against PA supporting its further evaluation as a potential vaccine candidate against paratyphoid A fever.

We examined NK cell phenotypes and functions after seven years of ART and undetectable viral loads (<50 copies/ml) with restored CD4 T-cell counts (≥500 cells/μl) and age-matched healthy-HIV-uninfected individuals from the same community.
Using flow-cytometry, NK cell phenotypes were described using lineage markers (CD56+/-CD16+/−). NK cell activation was determined by expression of activation receptors (NKG2D, NKp44 and NKp46) and activation marker CD69. NK cell function was determined by CD107a, granzyme-b, and IFN-gamma production.
CD56 dim and CD56 bright NK cells were lower among ART-treated-HIV-infected than among age-matched-HIV-negative individuals; p = 0.0016 and p = 0.05 respectively. Production of CD107a (P = 0.004) and Granzyme-B (P = 0.005) was lower among ART-treated-HIV-infected relative to the healthy-HIV-uninfected individuals. NKG2D and NKp46 were lower, while CD69 expression was higher among ART-treated-HIV-infected than healthy-HIV-uninfected individuals.
NK cell activation and dysfunction persisted despite seven years of suppressive ART with "normalization" of peripheral CD4 counts.

The development of HER2-targeted therapy has decreased recurrence rates and improved survival, transforming the natural history of HER2-positive breast cancer. However only a minority of breast cancer patients benefit as these agents are not used in patients with tumors expressing low levels of HER2. Preclinical data suggests a synergistic action of HER2-targeted vaccination with trastuzumab. We report the initial safety interim analysis of a phase II trial that enrolled patients with HER2 low-expressing (IHC 1+/2+) breast cancer who were clinically disease-free after standard therapy. Patients were randomized to receive the HER2-peptide vaccine nelipepimut-S + GM-CSF with trastuzumab (vaccine arm) or trastuzumab + GM-CSF (control arm) and were followed for recurrence. A planned analysis that occurred after enrollment of 150 patients showed no significant differences in toxicity between the two arms, including cardiac toxicity. The clinical efficacy of this combination will be reported 6 months after the final patient was enrolled.

Multiple sclerosis (MS) is an immune-mediated demyelinating disease of the central nervous system characterized by oligodendrocyte loss and progressive neurodegeneration. The cuprizone (CPZ)-induced demyelination is widely used to investigate the demyelination/remyelination. Here, we explored the therapeutic effects of Hydroxyfasudil (HF), an active metabolite of Fasudil, in CPZ model. HF improved behavioral abnormality and reduced myelin damage in the corpus callosum. Splenic atrophy and myelin oligodendrocyte glycoprotein (MOG) antibody were observed in CPZ model, which were partially restored and obviously inhibited by HF, therefore reducing pathogenic binding of MOG antibody to oligodendrocytes. HF inhibited the percentages of CD4+IL-17+ T cells from splenocytes and infiltration of CD4+ T cells and CD68+ macrophages in the brain. HF also declined microglia-mediated neuroinflammation, and promoted the production of astrocyte-derived brain derived neurotrophic factor (BDNF) and regeneration of NG2+ oligodendrocyte precursor cells. These results provide potent evidence for the therapeutic effects of HF in CPZ-induced demyelination.

Shellfish, including oysters, often cause allergic reactions in children and adults. Oysters are inevitably consumed because of its delicacy and nutritional benefit, leading to frequent occurrence of severe clinical symptoms observed in patients with oyster hypersensitivity. We aimed to identify the immunodominant epitopes of oyster tropomyosin and crucial amino acids for IgE binding, which will help us to further understand the immunochemical characteristics of Cra g 1. The potential epitopes were predicted by immunoinformatics tools and the resultant immunodominant epitopes were identified by inhibition ELISA with pooled sera and individual serum from oyster allergic patients. Surprisingly, homologous substitution of multiple amino acids led to obviously decrease affinity of IgE antibodies, but this manner did not abrogate binding completely. Five major linear epitopes were evenly distributed on the surface of homology-based Cra g 1 model and hydrophilic residues appeared to be the most important for IgE binding. These results not only offer a better understanding of the molecular mechanism of interaction between Cra g 1 and oyster-specific IgE but also have significance in clinical diagnosis and immunotherapy.

Bacillus Calmette-Guerin (BCG) is one of the most effective treatments for bladder cancer. Little attention has been paid to the possible role of neutrophils in BCG immunotherapy. In this study, we examined neutrophil extracellular traps (NETs) formation induced by BCG stimulation, and found that BCG-induced NETs exerted cytotoxicity, induced apoptosis and cell-cycle arrest, and inhibited migration in bladder tumor cells. BCG-activated tumor cells but not non-activated ones elicited NETs formation, in which IL-8 and TNF-α from activated tumor cells both took effect. Moreover, NETs activated peripheral blood mononuclear cells (PBMCs) exhibited a higher expression of CD4 and Th1 cytokines. Additionally, the role of NETs in vivo contributed to the recruitment of T cells and monocytes-macrophages and tissue damage, thus preventing tumor growth. NETs proteins mainly caused these effects on tumor and cellular immunity. In conclusion, we demonstrated a novel immunoregulatory role for NETs in the early stages of BCG immunotherapy.

Severe combined immunodeficiencies (SCID) comprise a group of genetic diseases characterized by abrogated development of T lymphocytes. In some case reports of atypical SCID patients elevated proportions of γδ T lymphocytes have been reported. However, it is unknown whether these γδ T cells modulate or reflect the patient's clinical phenotype. We investigated the frequency of elevated γδ T cell proportions and associations with clinical disease manifestations in a cohort of 76 atypical SCID patients. Increased proportions of γδ T lymphocytes were present in approximately 60% of these patients. Furthermore, we identified positive correlations between elevated proportions of γδ T cells and the occurrence of CMV infections and autoimmune cytopenias. We discuss that CMV infections might trigger an expansion of γδ T lymphocytes, which could drive the development of autoimmune cytopenias. We advocate that atypical SCID patients should be screened for elevated proportions of γδ T lymphocytes, CMV infection and autoimmune cytopenias.

We sought evidence for direct effects of repository corticotropin (RCI; an FDA-approved treatment for selected cases of SLE) on isolated human B lymphocytes activated by engagement of TLR9 and B cell receptors. ODN 2395/αIgM treatment was found to result in induction of 162 distinct mRNAs and suppression of 80 mRNAs at 24 h. RCI treatment resulted in suppression of 14 of the ODN 2395/αIgM -induced mRNAs (mean suppression to 23.6 ± 3.1% of stimulated value). The RCI-suppressed mRNAs included two critical regulators of class switch recombination, AICDA and BATF. RCI treatment also resulted in induction of 5 of the ODN 2395/αIgM -suppressed mRNAs (mean induction by RCI = 7.65 ± 2.34-fold). The RCI-induced mRNAs included SLAMF3, a cell surface receptor capable of inhibiting autoantibody responses. These studies reveal that RCI treatment of human B cells reverses key elements of the early mRNA response to TLR9 and B cell receptor engagement.

Alexandria Journal of Pediatrics 2018 31(3):91-96
Background Congenital heart disease (CHD) is one of the most common congenital anomalies. It may carry risk of neurodevelopment (ND) delay. Open heart surgery has been widely introduced to those patients. The outcome of this surgery on patient’s development is unclear. Objective The aim was to evaluate ND outcomes in children with CHD who underwent open heart surgery. Patients and methods Fifty children with CHD were enrolled in this study: 23 were surgically repaired (group 1) and 27 had no surgical intervention (group 2). Twenty normal children of matched age and sex were enrolled in the study as controls (group 3). Bayley-III test was used to compare the ND parameters in all groups. Results ND aspects showed lower significant differences in groups 1 and 2 when matched with the control group (P<0.05). However, there were no significant differences in ND parameters between groups 1 and 2 in gross motor and receptive communication parameters (P>0.05). Conclusion CHD carries the risk of ND delay, and exposure to open heart surgery increases this risk.

Background Autism spectrum disorders (ASD) are a group of neurodevelopmental disorders characterized by impairment of social interaction, communication, and behavior. It has been recently suggested that ASD are characterized by abnormal brain networks and connectivity, which was studied using neuroimaging modalities. Objective The aim of this study is to assess the quantitative electroencephalographic (QEEG) findings in children with ASD compared with age-matched children and to assess if QEEG analysis is a sensitive and simple method to aid in the diagnosis of ASD in children. Patients and methods QEEG recordings of 50 children with ASD between the ages of 2 and 6 years were compared with those of 50 age-matched controls under eyes-closed condition. Brain functioning and its connectivity were examined using measurements of spectral analysis of both absolute and relative power and interhemispheric coherence. Results There were statistically significant differences in electroencephalogram spectral power and coherence between the study and control groups. It revealed an increased absolute delta power in the frontal, anterior temporal, midtemporal, central, and parietal regions and an increase of absolute alpha power mainly in the prefrontal and frontal regions. There was a greater beta power in midtemporal and posterior temporal regions. In addition, interhemispheric coherence showed a pattern of frontal overconnectivity and temporal underconnectivity with the other brain areas in children with ASD in comparison with the control group. Moreover, statistical differences in electroencephalogram spectral power and coherence between the different grades of children with ASD were noticed. Conclusion These results suggested that children with ASD have QEEG dysfunctions that underlie their symptomatology. Hence, QEEG provides a useful method that aids in the diagnosis of children with ASD.

Patients and methods The degree of dehydration was assessed clinically via clinical dehydration scale and by portable ultrasonography. Measurements of IVC diameters and IVC/Ao ratio were performed. IRB approved the study. Statistical analysis used Mann–Whitney test were used to compare nonparametric data. Sensitivity and specificity were tested by receiver operating characteristic curves. Results Eighty-one children, aged from 1 month to 3 years, were enrolled in this study; 41 presented with some dehydration and 40 with moderate/severe dehydration, classified according to the clinical dehydration scale. There was a statistically significant positive correlation between dehydration degree and IVCCI and IVC/Ao ratio (r=0.67 and 0.54, respectively, P=0.001 each). When plotting the receiver operating characteristic curve for IVCCI, area under the curve was 0.81, using a cutoff value of 73%, the sensitivity and specificity, for the detection of dehydration degree, were 90 and 71%, respectively, while for IVC/Ao ratio, the area under the curve was 0.78, with a cutoff value of 0.8, the sensitivity and specificity were 90 and 64%, respectively. Conclusions Measurements of IVCCI and IVC/Ao ratio aid in the detection of the degree of dehydration in infants and children with high sensitivity and moderate specificity.

Background Biliary atresia (BA) is the most common surgically correctable liver disorder in the pediatric age group. If untreated, progressive liver cirrhosis leads to death by the age of 2 years. Aim The aim was to study the outcome of Kasai portoenterostomy for infants with BA in Egypt and identify some prognostic factors of this outcome. Patients and methods A prospective clinical and laboratory study including 20 patients with BA who underwent Kasai operation was conducted. A detailed history taking, clinical examination, liver function tests, ultrasound of the abdomen, preoperative liver biopsy, and intraoperative cholangiography were done for all patients. Patients were followed up for a period of 6 months postoperatively. The schedule and indications for liver transplantation were also evaluated. Results Overall, 55% of operated infants showed gradual reduction of serum bilirubin, which reached a level less than 2 mg/dl, as well as reduction of liver enzymes. On the contrary, the remaining 45% of infants failed to show satisfactory reduction of serum bilirubin, which continued to be greater than 2 mg/dl as well as liver enzymes. Both groups showed statistically significant differences regarding age at operation, presence of preoperative ascites, liver size, and patients’ Child–Pugh score. Moreover, preoperative total serum bilirubin and its direct fraction, liver enzymes, and cholestatic enzymes were significantly higher among infants with a bad outcome. There were no mortalities within the 6-month follow-up period. Conclusion Kasai portoenterostomy showed better results with short-term follow-up if done at an early age. Certain preoperative clinical, laboratory, radiological, and pathological factors might predict the outcome of Kasai operation.

Ahmed F Khalil, Mohamed Alkot
Alexandria Journal of Pediatrics 2018 31(3):120-127
Background Functional constipation is a common health problem in the pediatric age group. Delayed management leads to a significant childhood morbidity. Aim The purpose of this study is to evaluate the prevalence, precipitating factors, and clinical characteristics and management of children with functional constipation in our community. Patients and methods This work was performed as a prospective study that included all children aged 1–15 years with functional constipation who presented to the Pediatric Gastroenterology Clinic at Alexandria University Children’s Hospital between August 2015 and January 2016. Demographic data, precipitating factors, clinical characteristics, and prereferral management were recorded. All patients were treated and followed up for at least 4 months. Results During the study period, 86 patients were enrolled. They constituted the most important cause for referral to the Gastroenterology Clinic during the study period. Most of the patients were living in low to middle socioeconomic status and were belonging to mothers of low to intermediate level of education. Low-fiber diet, diminished fluid intake, and urge postponing when present at public places were the commonest risk factors for developing constipation. Family history of constipation was positive in 32.6% of patients. The mean duration of complaints before presentation to our clinic was 19.22±22 months. Chronic abdominal pain was the most common presenting symptom (77.9%). Only 28% of the parents were aware that their children are constipated. The passage of hard painful stools was the most common character of stool in the studied group (98.8 and 95.3%) followed by infrequent evacuations (<4/week) in 85% of patients. Of the patients, 24.4% had fecal soiling. Urinary symptoms were present in 39.5%. Abdominal distention and palpable fecal mass were found in 83.7 and 67.5%, respectively. Only one-third of the patients were correctly diagnosed as having chronic constipation. None of the studied children were previously treated properly according to the accepted guidelines for functional constipation. Our cases were referred very late when they develop debilitating abdominal pain due to massive stool impaction or present with stool incontinence. Oral disimpaction was successful even in severely constipated children. All clinical symptoms and stooling characteristics were significantly improved after treatment. Conclusion Functional constipation is a very common, yet underestimated, underdiagnosed, and maltreated health problem our community.

Maha Y Kamal, Wessam El Gendy, Ahmed Salama
Alexandria Journal of Pediatrics 2018 31(3):128-131
Background Bone marrow examination is the gold-standard test in discriminating between hyperdestructive thrombocytopenia and hypoproductive thrombocytopenia. However, this procedure is invasive. Mean platelet volume (MPV) and platelet distribution width (PDW) are simple, inexpensive, and noninvasive methods that may be used in discriminating between these two types of thrombocytopenia. Aim This study investigated the significance of the platelet indices, MPV and PDW, in the diagnosis of immune thrombocytopenic purpura (ITP). Patients and methods The study population were divided into three groups: 15 patients with hyperdestructive thrombocytopenia and 15 with hypoproductive thrombocytopenia were compared with control group (15 healthy controls). The sensitivity and specificity of these platelet indices to diagnose immune thrombocytopenic purpura were also measured. Results The MPV showed a sensitivity of 93.3% and a specificity of 66.7% at a cutoff value of 7.7 fl, and the PDW showed a sensitivity of 86.7% and specificity of 73.3% at a cutoff value of 40.6%. Conclusion The study concluded that although MPV and PDW can be used as an initial hint for predicting the type of thrombocytopenia, they have limited sensitivity and specificity.

Mahmoud M.E El Kersh, Ola A Sharaki, Omneya M Omar, Yasmine A.S Galal
Alexandria Journal of Pediatrics 2018 31(3):132-140
Background The chief complications of nephrotic syndrome (NS) are infections and thromboembolic events. Others include hypovolemic crisis, acute renal failure, and hormonal and mineral alterations. Objective The aim was to study the level of serum ionized calcium during the active stage and after remission in steroid-sensitive nephrotic syndrome (SSNS) patients and 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH) during the active stage of the disease. Patients and methods The study was conducted on two groups. Twenty children with the first episode of SSNS were investigated and compared with 20 healthy children as a control group. Serum ionized calcium, serum 25(OH)D, PTH, phosphorus, and alkaline phosphatase were measured during the active stage of the disease and serum ionized calcium was repeated after remission. Results Children with active SSNS had low ionized calcium, low-serum 25 (OH)D levels, with high PTH and high phosphorus and low alkaline phosphatase levels compared with the control. All patients had 25(OH)D deficiency, of which, 80% were severely deficient. Both serum ionized calcium and 25(OH)D had a significant negative correlation with PTH (r=−0.655, P=0.002 and r=−0.575, P=0.008, respectively). Serum ionized calcium was negatively correlated to spot protein/creatinine ratio in urine (r=− 0.565, P=0.009). Levels of serum ionized calcium during the active stage of the disease were markedly lower than that after remission. However, both were significantly lower than the control group. Conclusion Children with SSNS are at risk of vitamin D deficiency and hypocalcemia, therefore, further research will be needed to prove the need for vitamin D supplementation to prevent the occurrence of possible complications.

Mai M Ghazy, Hanan A El-Halaby, Amr M El-Sabbagh, Ali A Shaltout
Alexandria Journal of Pediatrics 2018 31(3):141-147
Background Early recognition and management of sepsis is a challenge facing intensivists. Many biomarkers were investigated but none is optimal. Aim Appraise the value of presepsin as a biomarker for the diagnosis, differentiation of severity, and prognosis of sepsis. Settings and design A prospective diagnostic test accuracy study performed in Mansoura University Children’s Hospital from April 2016 to April 2017. Patients and methods Plasma presepsin was estimated in 30 patients with sepsis on the first and third days from sepsis diagnosis (group A). Pediatric sequential organ failure assessment score, white blood cells count, and C-reactive protein were assessed on the same timing. Group B patients, 30 healthy patients, were assessed for presepsin level. IRB approved the study. Statistical analysis Independent sample t-test was performed to compare parametric data. Receiver operating characteristic curves were used to detect threshold values. Results A significantly higher presepsin level in the sepsis group (983 ng/l) compared with the healthy group (300 ng/l, P=0.001) was detected. A statistically significant higher serum presepsin level on day 3 was noticed in patients with severe sepsis opposed to sepsis and in nonsurvivors versus survivors (P=0.041 and 0.012, respectively). Receiver operating characteristic curve for plasma presepsin level on day 3 for the prediction of 30-days mortality was designed. Sensitivity and specificity were 86 and 73%, respectively, for a threshold point of 1300 ng/l [area under the curve (AUC)=0.820, P=0.001]. Conclusion Presepsin is a diagnostic marker for sepsis, a good discriminator of sepsis severity, and a sensitive predictor of 30-day mortality, but it should not be alone but in combination with other biomarkers.

Sambhaji Raut, Chandrakant Chavan, Deepak Phalgune
Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):1-6
Introduction: Large number of patients with heart failure (HF) have left bundle branch block (LBBB). Most precise method for identification of intraventricular dyssynchrony is tissue Doppler imaging (TDI). Purpose of this research was to compare left ventricular (LV) mechanical dyssynchrony in LBBB patients with and without HF and to compare various methods of LV systolic dyssynchrony assessment by TDI. Materials and Methods: One hundred and sixteen patients with a diagnosis of LBBB were included in the study. All patients underwent conventional two-dimensional echocardiography for global LV function assessment. LV systolic dyssynchrony was measured by opposing wall delay, maximum delay, and Yu index. LBBB patients were grouped into four classes according to their LV function and the presence or absence of HF, normal LV function without HF (Group A), normal LV function with HF (Group B), LV dysfunction with HF (Group C), and LV dysfunction without HF (Group D). Results: LV systolic dyssynchrony was significantly higher (P <0.001) in Group C and D as compared to Group A and B. LV systolic dyssynchrony was significant higher in Group C and D as compared to Group A and B by using opposing wall delay (P <0.001), Yu index (P <0.001), and maximum delay (P <0.001) imaging criteria. Mean Yu index (P <0.001) and mean maximum delay (P <0.001) were significantly higher in Group C and D as compared to Group A and B. Conclusions: LV systolic dyssynchrony was more common in LBBB patients with LV dysfunction than those with normal LV function, irrespective of the presence or absence of HF.

|Trans-esophageal echocardiography during off-pump coronary artery bypass grafting|
TA Patil, Santosh Kumar Ambli, Vaishali S Badge
Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):12-16
Off-pump coronary artery bypass grafting (OPCABG) is fast becoming widely adopted technique for surgical revascularization of the heart. However, OPCABG presents with unique technical and hemodynamic challenges which require additions to conventional monitoring techniques. Transesophageal echocardiography (TEE) provides reliable and real-time information to monitor these challenges during OPCABG. TEE is an invaluable diagnostic tool for real-time imaging during OPCABG. It is beneficial not only in the intraoperative period but also in the postoperative care units for better patient outcomes.
|Constrictive pericarditis in association with ischaemic heart disease|
Rajesh Krishnachandra Shah
Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):17-22
Constrictive pericarditis (CP), a not so common condition, has symptoms and signs of heart failure and abnormal echocardiographic findings, such as jerky septal motion. These findings can be mistaken for ischemic heart disease (IHD) if the echocardiographer is inexperienced. Although the etiology of CP can be varied such as idiopathic, postviral, tuberculous, postsurgical, and radiation-induced the final common pathway is the development of fibrous thickening or calcification of the visceral pericardium resulting in pericardial noncompliance, and ultimately requiring surgical intervention. As CP is potentially reversible and surgically curable condition, with improvement in symptoms and quality of life, the diagnosis should not be missed. Here, we present a case in which the diagnosis of CP was made, and subsequently found to have IHD also.

Mehul Popatlal Oswal, Chandrashekhar Kashinath Ponde
Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):23-26
Constrictive pericarditis (CP) is characterized by thick pericardial fibrosis and calcification that causes progressively impaired diastolic filling of the heart with associated symptoms of heart failure. Rarely, it can also present as localized CP and depending on the CP location, clinical presentation can be variable, including compression and obstruction of right ventricular inflow tract, coronary obstruction, or pulmonary stenosis. We report a rare case of isolated constriction of the right side of the heart due to loculated tuberculous pericardial effusion.

Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):30-32
The azygos lobe was first discovered by an anatomist Dr. Heinrich August Wrisberg in the year 1877. It is a rare normal variant of the lung usually present over the right lobe. The azygos lobe has been reported in various case reports where it has been mistaken to be a neoplasm, a bulla, or a paratracheal mass. It has implications in the field of surgery as well when this anatomic variant was discovered during sympathectomy and the approach had to be slightly altered. We present a rare case of an incidental finding of an azygos lobe impinging over the superior vena cava and causing axial alteration of the heart.

Sanjay Nathani, Pooja Mehta, Kapisoor Singh, Sandeep Golcha
Journal of The Indian Academy of Echocardiography & Cardiovascular Imaging 2019 3(1):33-35
Coronary circulation anomalies are the uncommon cause of chest pain when hemodynamically significant. Multidetector computed tomography (CT) of coronary arteries is rapidly replacing conventional angiography, nowadays, as the first line of investigation for the imaging of coronary artery disease due to its noninvasive nature. CT coronary angiography in addition to diagnosing anomalies of coronary arteries is especially good in the delineation of ostial origin and proximal course. Superdominant right coronary artery (RCA) with absent left circumflex artery (LCx) is such a rare congenital coronary artery anomaly which can mimic atherosclerotic disease clinically with very few case reports in the literature which can be diagnosed and evaluated with accuracy by CT angiography.

|Prevalence of oral Candida in saliva of uncontrolled and controlled type 2 diabetes mellitus patients – Beyond reasonable doubt?|
Saramma Mathew Fenn, Mohan Narayanan, Mathew Jacob
SRM Journal of Research in Dental Sciences 2019 10(1):1-6
Aim: The aim of this study was to compare the prevalence of Candida in the saliva of uncontrolled and controlled group of type II diabetic and in nondiabetic individuals. Settings and Design: This was a cross-sectional study. Subjects and Methods: Total study group consists of 75 type 2 diabetic patients, in which 25 patients in Group I were taken as controlled diabetics, 25 patients in Group II were considered as uncontrolled diabetics, and 25 patients were considered as nondiabetics, control group in Group III, respectively. Statistical Analysis Used: Student's t-test, Chi-square test, and one-way ANOVA test were used in this study. Results: In this study, a total of 75 patients were included, of which a total of 30 saliva samples had shown the presence of candidial growth. Out of 25 saliva samples collected from Group I (controlled diabetic patients), 11 samples showed the presence of candidial growth and out of 25 samples collected from Group II (uncontrolled diabetic patients), 19 samples showed the presence of candidial growth. Samples obtained from Group III (nondiabetic patients) were negative for any candidial growth. A significant difference was observed in candidial growth from saliva samples obtained between the various study groups. The uncontrolled diabetic patients group showed a higher candidial colony-forming unit when compared with that of controlled diabetic patients group. Conclusion: The prevalence of Candida in the oral cavity of patients with diabetes is of primary concern for dentists in the early detection of opportunistic infections, such as oral candidiasis, by understanding the predisposing local and systemic factors. The habitat provided by the predisposing disease may, beyond reasonable doubt, reset the microbiological environment to favor the proliferation and colonization of opportunistic microorganisms such as the oral commensal, Candida.

Jimsha Vannathan Kumaran, Mariappan Jonathan Daniel, Mithunjith Krishnan, Sruthi Selvam
SRM Journal of Research in Dental Sciences 2019 10(1):12-16
Introduction: Salivary gland neoplasm represents the most complex and diverse group of neoplasm of the head and neck. Their diagnosis and management are complicated by relative infrequency. Around 64%–80% are located in the parotid gland, 7%–11% in the submandibular glands, and the remainder being distributed between the sublingual (1%) and the minor salivary glands (9%–23%) throughout the oral cavity. Aim: The aims of this study were: (1) To assess the frequency of salivary gland tumor based on tumor type and anatomic location. (2) To correlate gender and age in different tumor type. (3) To correlate the location of benign and malignant tumors. Subjects and Methods: A retrospective study was made in the Department of Oral Medicine and Radiology from the period of January 2006 to December 2017. Data were collected from the archives maintained in the Department of Oral Medicine, and details of the patient include age, sex, and site of the tumor were obtained and confirmed with histopathological study and sent for statistical analysis. Results: Chi-square test was applied to find the distribution of malignant and benign tumors. The prevalence of salivary gland tumors in our study was 0.3%, and the benign: malignant ratio was 1:2.2, with the mean age of occurrence was 45.01 ± 16.3 years with slight overall female predominance and a male-to-female ratio of 0.7–0.9, respectively. Conclusion: The present study was a single-institutional experience where the analysis of 32 SGTs was carried out. Malignant tumors were more compared to benign. Among benign tumors, pleomorphic adenoma was the most common type. Among the malignant salivary gland tumors, mucoepidermoid carcinoma was the most common, followed by adenoid cystic carcinoma then ex-pleomorphic adenocarcinoma followed by low-grade polymorphous adenocarcinoma.

SRM Journal of Research in Dental Sciences 2019 10(1):17-20
Introduction: Dental skills based on sound theoretical knowledge are the basis for a dental student to become a good dentist. The 3rd and 4th years of Bachelor of Dental Surgery requires integration and application of clinical knowledge, skill, and attitude. However, to understand this integration, there is a paucity of literature on the dental students' learning preferences, especially in the Indian scenario. Hence, the objective of the present study is to provide information about it. Materials and Methods: VARK questionnaire (VARK is an acronym that stands for visual [V], aural [A], read [R], and kinesthetic [K] sensory modality of learning) was used to evaluate the learning preferences of clinical dental students. This multicentric study included 350 students from four dental colleges in India. Statistical Analysis: Strong preference was calculated on Microsoft Excel using the VARK guidelines. Likert scale (1–5) was used to know their perceptions of their VARK score. Results: Majority of the students were multimodal with many students showing two preferences. Kinesthetic modality was the strongest single preference and visual was the weakest single preference. Conclusion: Majority of the students are multimodal in their learning preferences with kinesthetic modality showing strong single preference. Teachers can help students to develop learning preferences based on their preferences of learning. Teaching methodology should involve all sensory modalities so that all kinds of students can actively participate in learning process.

Derya Icoz, Faruk Akgunlu
SRM Journal of Research in Dental Sciences 2019 10(1):21-25
Objectives: Some calcifications of the head and neck region may be seen on dental panoramic images due to the superimpositions and proximity of structures. The aim of the present study was to evaluate the prevalence of soft tissue calcifications observed on digital panoramic images and the relationship of the calcifications with age and gender. Materials and Methods: Four thousand two hundred and sixty-three digital dental panoramic radiographs of the individuals aged between 6 and 89 who had visited the faculty of dentistry for different oral and dental complaints were evaluated retrospectively and detected calcifications were recorded with the age and gender information. Data were analyzed by means of descriptive statistics, Pearson Chi-squared, and independent samples t-test. Results: Two hundred and seventy calcifications (6.4%) were detected in the whole study population. Observed calcification types were tonsillolith (2.5%), carotid artery calcification (2.3%), sialolith (1%), and calcified lymph node (0.6%). The prevalence of calcifications for all types increased with age (P < 0.001). Conclusions: The prevalence of calcifications seen on the dental panoramic images is relatively rare, but the detection during routine dental examinations is important in terms of the need for more detailed evaluation of the patients.

Introduction: Oral cavity cancer is the third most common cancer in India. It presents a major burden on health services in India due to the widespread and rampant use of tobacco. Moreover, as per the Indian Council of Medical Research 2016 data, it ranks the fifth in overall mortality rate among different cancers prevalent in India. Aims and Objectives: The aim was to study and present our data on patient- and tumor-related factors as well as overall survival (OS) among patients of oral cavity cancer treated with surgery and radiotherapy at our center. The objective was to find the difference in OS in various subgroups of patients at 2 and 5 years from treatment. Materials and Methods: This was a retrospective study carried out in a tertiary care center of North India. The data collected were of patients treated between November 12 and November 16. A total of 112 cases of oral cavity cancers were studied. The patient-related variables that were analyzed included age, gender, history of tobacco or alcohol use, and presence of preexisting comorbidities. The tumor-related factors that were studied were tumor subsite, stage, and histological grade. OS of patients with varying parameters was compared at 2 and 5 years. Results: OS at 5 years for Stage I was 100% and decreased to 85% for Stage II. For Stages III and IV, the 5-year survival was a mere 43% and 42%, respectively. Conclusion: Treatment results at our center were comparable to world literature.

Aims: The goal of this study was to assess the smoking cessation advice (SCA): Attitude, practice, and barriers among dental students of Hazaribag College of Dental Sciences and Hospital, Hazaribag, Jharkhand, India. Subjects and Methods: The study population comprises of a total of 217 clinical dental students studying in Hazaribag College of Dental Sciences and Hospital. Data were obtained using a self-administrated questionnaire comprising of 25 multiple choice questions, based on Likert scale. Attitude-6, Practice–14, Barriers-5. The qualitative analysis on the distribution of opinion was assessed using Chi-square test, P < 0.05 was considered statistically significant. Results: The results of the present study showed that the attitude and practice of house surgeons were better than that of third and final year students for questions based on attitude toward smoking cessation questions such as – How effective do you think smoking cessation counseling provided by dentists? (P < 0.05), based on Practice in tobacco smoking cessation: Do you refer patients to appropriate service to help them stop smoking? (P < 0.05) were statistically significant. Conclusions: Despite having knowledge of smoking associated health risks and positive attitudes toward giving SCA to patients, dental students in the clinical scenario witnessed barriers to provide SCA. To ensure that when students graduate from dental school, they should not only have good knowledge but the confidence to provide effective SCA and be able to refer to specialists trained in smoking cessation programs. In conclusion, tobacco cessation advice, counseling of patients and referral to appropriate sources for treatment needs to be included as a part of the BDS curriculum to acquire skills in this aspect of dentistry.

SRM Journal of Research in Dental Sciences 2019 10(1):40-46
The aim of this paper was to study and compare the levels of copper (Cu), iron (Fe), and zinc (Zn) in patients with premalignant lesions or malignant conditions. A schematic search was conducted according to population, intervention, comparison, outcome in order to obtain appropriate articles for critical appraisal. The review incorporated a total of 16 articles, including in vivo human studies published in English language. Studies with premalignant and malignant conditions and trace elements including Cu as an essential element and Fe and Zn as other elements were considered. No limit was placed on a number of patients and studies involving blood investigations were included in this review. The exclusion criteria were in vitro nonhuman non-English studies. Case series, case reports, retrospective studies, and studies involving only saliva/tissue investigations were also excluded and studies not having any of the above-mentioned trace elements were also excluded from the study. Results of the studies suggested that serum Cu and Zn as well as the Cu to Zn ratio can be used as biomarkers for oral precancer and cancer. Thus, a comprehensive understanding of these trace elements can be used as a reliable biomarker for development and progression of oral cancer.

|Congenital midline labial sinus of the upper lip|
Anka Sharma, Subhash P Kumbhare, Ashita Kalaskar
SRM Journal of Research in Dental Sciences 2019 10(1):53-56
Congenital midline labial sinus is a rare condition affecting both the upper and lower lips. This anomaly has been reported in either gender but with a slightly increased predilection in females. It is known to occur either in isolation or in association with other congenital malformations such as cleft lip, cleft palate, van der Woude syndrome, median lip pit, brachidactilia, tongue tie, hypertelorism, notch of median vermillion border, nasal fistula, and abnormal hair pattern. In this article, we report a case of congenital midline sinus (without any associated congenital malformation) affecting the upper lip in a 12-year-old Indian male. Furthermore, a review of literature has been attempted on this condition.

|Epigenetic transmission of maternal behavior: Impact on the neurobiological system of healthy mothers|
Alya Elmadih, Mahdi Abumadini
Saudi Journal of Medicine and Medical Sciences 2019 7(1):3-8
Quality of maternal caregiving not only impacts children's development but can also result in heritable changes in gene expression (i.e., in an epigenetic manner). Consequently, when women become mothers, they adopt parenting behavior similar to that they received at family of origin. This transgenerational transmission of maternal behavior may also be associated with changes in the neurobiological system of future mothers. This review aims to highlight the effect quality of perceived parenting has on maternal behavior and the neurobiological system of mothers, specifically the oxytocin system, brain morphology and brain function. This would likely help in finding biomarkers that profile the impact of perceived parenting on mothers, and thus allow identification of mothers who experience poor-quality parenting for intervention.

Ayman Hussain Jawadi, Mohammed Benmeakel, Moath Alkathiri, Maha A Almuneef, Winnie Philip, Manal Almuntaser
Saudi Journal of Medicine and Medical Sciences 2019 7(1):9-15
Background: Child abuse is a major problem globally. Nonaccidental fractures are the second most common injury among physically abused children; however, there is a lack of studies describing the characteristics of nonaccidental fractures in Saudi Arabia. Objectives: The objective of this study was to determine the characteristics of nonaccidental fractures among abused children in Riyadh, Saudi Arabia, using radiography. Materials and Methods: This retrospective study analyzed the data and radiographs of all nonaccidental fracture cases in children (aged ≤14 years) registered in the National Family Safety Program Registry at King Abdulaziz Medical City, Riyadh, between 2009 and 2015. Results: A total of 1512 cases of child abuse were found in the National Family Safety Program Registry database from Riyadh city. From these, 103 fractures were identified; however, radiographs were available for only 70 fractures from 56 children. Of these, 33 (59%) were boys, and 25 (45%) were aged 1–5 years. In terms of the type of abuse, neglect was more common than physical abuse (52% vs. 45%). History of injury was identified in 75% (42) of the cases, of which fall accounted for about 55% (23). Nearly 79% of children presented with a single bone fracture, while 21% had multiple bone fractures. The most common sites of fractures were skull (40%), upper limbs (31%) and lower limbs (29%). The most common fracture pattern was transverse fractures (48%), and it was mainly diagnosed in skull fractures (51%). Conclusions: This study found that in Riyadh, Saudi Arabia, neglect is the most common cause of nonaccidental fractures, abusive head trauma is the most commonly associated injury and transverse fracture is the primary pattern of fracture in abused children. Notably, as most children experienced a single-bone fracture, the authors recommend clinicians to lower their threshold of considering abuse even in cases with an isolated fracture.

Saudi Journal of Medicine and Medical Sciences 2019 7(1):16-21
Background: Endometrial carcinoma is a predominant health problem for women worldwide. However, there is a lack of data on genetic mutation frequencies in endometrial cancer patients of different ethnicities and tumor grades. Objective: The objective of this study is to provide data regarding mutation frequencies in endometrial cancer patients of different ethnic groups and tumor grades by analyzing large-scale cancer genomic datasets of a database. Materials and Methods: The following databases of cBioPortal were explored for possible mutation frequency variations in endometrial cancer patients: the Uterine Corpus Endometrial Carcinoma (TCGA, PanCancer Atlas) database for ethnicity-based studies; the Uterine Corpus Endometrial Carcinoma (TCGA, Nature 2013) database for tumor grade-based study; and GDC Data Portal database for calculating survival rates using the Kaplan–Meier method. Results: PTEN mutation frequency was almost identical in all ethnic groups studied (White, Black/African American, Asian, Native Hawaiian or other Pacific Islander, and American Indian or Asian Native). PIK3CA and ARID1A mutation frequencies were higher in White and Asian patients compared with other ethnicities; TP53 and FAT1 mutation frequencies were higher in Black/African Americans; and CTNNB1 and RYR2 mutation frequencies were higher Native Hawaiians or Asian Natives. TTN mutation frequency was lower in Asian patients. With regards to mutation frequencies at different tumor stages, in all genes, >50% of the mutations occurred during the first stage, except in TP53 and POLQ. In terms of prognosis in endometrial cancer considering the 10 most frequently mutated genes, PIK3CA and ARID1A mutations were correlated with good prognosis, whereas TP53 and PIK3R1 mutations were correlated with poor prognosis; mutations in all other genes did not show significant differences. Conclusion: This study revealed a new mutation frequency profile for different ethnicities and tumor grades in endometrial cancer patients. However, because this is a retrospective study, future prospective studies should be conducted including large sample sizes and more controlled measurements.

Saudi Journal of Medicine and Medical Sciences 2019 7(1):22-27
Background: The diagnosis of diabetic nephropathy is based on the course of clinical manifestations and renal biopsy. Renal biopsy is usually performed in patients with atypical presentations. Objectives: This study was performed to analyze various renal histopathological lesions in diabetic patients and to establish a clinicopathological correlation. Materials and Methods: In this retrospective study, the authors analyzed renal histology of 40 patients with type 2 diabetes mellitus who presented with atypical features of diabetic renal involvement and underwent renal biopsy at the Military Hospital Mohammed V, Rabat, Morocco, between January 2008 and December 2016. Results: About 60% of the patients had isolated diabetic nephropathy, 35% had isolated nondiabetic renal diseases and 5% had both. Patients with nondiabetic renal diseases had significantly higher hematuria (P = 0.02), shorter duration of diabetes (P = 0.009), higher mean estimated glomerular filtration rate (P = 0.04) and lower prevalence of diabetic retinopathy (P < 0.001). The most common histological lesion in patients with nondiabetic renal diseases was IgA nephropathy (25%). In patients with diabetic nephropathy, the most common histological class was Class III (42.3%). Furthermore, higher histological classes were associated with lower estimated glomerular filtration rate (P < 0.001) as well as higher prevalence of diabetic retinopathy (P = 0.009) and nephrotic proteinuria (P = 0.04). Conclusions: This study found that in Rabat, Morocco, the most common histopathological lesion in patients with diabetes was diabetic nephropathy. Hematuria, shorter duration of diabetes, higher mean estimated glomerular filtration rate and lower prevalence of diabetic retinopathy were reported among those with nondiabetic renal diseases. These findings are in accord with that of studies from other countries. However, large sample size and long-term follow-up clinical studies are needed to demonstrate the renal pathological implications and renal outcomes in type 2 diabetes mellitus patients with renal involvement.

Saudi Journal of Medicine and Medical Sciences 2019 7(1):28-32
Background: In Saudi Arabia, the prevalence of toxoplasmosis is high. However, to date, few studies have evaluated the degree of knowledge on toxoplasmosis among females in Saudi Arabia. Objectives: The objective of this study was to assess the knowledge, attitude and preventive behavior regarding toxoplasmosis among female students at Jazan University, Jazan, southwest Saudi Arabia. Materials and Methods: This cross-sectional study was conducted on a random sample of 440 female students at Jazan University using a semi-structured, self-administered questionnaire. Data with numerical/qualitative variables were expressed as frequency and percentage. Chi-square test was used to analyze categorical variables. P < 0.05 was used to indicate statistical significance. Results: This study found that more than three-quarters (79.1%) of the students had insufficient knowledge about toxoplasmosis. Students from healthcare faculties had higher knowledge scores (28.5%) than students from arts and humanities (20.6%) and science (18.9%) faculties; however, the differences were not statistically significant (P = 0.77). The majority of the studied sample (92.3%) was found to eat fast food on a regular basis. About 42%, 54% and 4% of the respondents reported that they never, occasionally and always ate improperly washed vegetables, respectively. Conclusions: This study found that a substantial proportion of Jazan University's female students have insufficient knowledge on toxoplasmosis. Health educational programs are necessary to increase the awareness and knowledge about toxoplasmosis and its clinical manifestations.

Abdulrazag H Al-Salameen, Hassan A Abugad, Sultan T Al-Otaibi
Saudi Journal of Medicine and Medical Sciences 2019 7(1):33-39
Background: Back pain is common among factory workers and is responsible for about 25% of workers' compensation cases. However, data on back pain among workers from paint industry in Saudi Arabia are limited. Objectives: The objective of this study is to estimate the prevalence of low back pain and to evaluate the associated risk factors among workers of a paint factory. Materials and Methods: This cross-sectional study used a self-administered questionnaire to elicit data regarding demography, job characteristics and prevalence of low back pain in the past 12 months among workers of a paint factory (n = 102) in the Eastern Province of Saudi Arabia. In addition, a scale of low back pain risk was generated for each department by occupational health professionals using interviews and observations. Results: The annual prevalence of low back pain was 44.1%, and it was more common among Saudi workers (67.9%) compared with non-Saudi workers (35.1%). Multivariate analysis indicated significant associations between low back pain and nationality (relative risk [RR] = 1.93; 95% confidence interval [CI] = 1.29–2.88), smoking (RR = 1.85; 95% CI = 1.20–2.83) and aerobic exercise (RR = 2.37; 95% CI = 1.19–4.71). Spearman rank correlation showed correlation between the symptom pain scale and smoking (rs = 0.259; P = 0.008), and exercise was associated with lower pain scale scores (rs= −0.241, P = 0.015). Conclusion: This study found that low back pain is common among paint factory workers in the Eastern Province of Saudi Arabia. Nationality and smoking are risk factors for low back pain and are associated with each other. Many workers did not exercise, and lack of exercise was associated with an increased risk of low back pain. Reducing smoking and increasing exercise in addition to workplace ergonomic intervention may reduce this frequently occurring problem.
|Visceral leishmaniasis and glomerulonephritis: A case report|
Marwan Jabr Alwazzeh, Zaki Hajji Alhashimalsayed
Saudi Journal of Medicine and Medical Sciences 2019 7(1):40-43
Visceral leishmaniasis is an endemic in the southwestern region of Saudi Arabia, with a low incidence rate. Clinical presentations of visceral leishmaniasis include recurrent fever, substantial weight loss, hepatosplenomegaly and anemia. However, the clinical features may not be easily evident owing to the involvement of multiple organs. This, in turn, can cause difficulties in establishing the correct diagnosis, and subsequently, in managing the patient. Here, the authors report a case of a 42-year-old male from Jizan, southwestern Saudi Arabia, who presented with impaired renal function. After kidney biopsy, the patient was diagnosed with glomerulonephritis of unknown etiology and treated with mycophenolate and prednisone. After 3 months, the patient developed high fever with hepatomegaly and pancytopenia. Based on the investigations, a possible diagnosis of visceral leishmaniasis was considered. Accordingly, he was treated with liposomal amphotericin B, following which his condition improved significantly. This case report discusses the relationship between glomerulonephritis and visceral leishmaniasis and focuses on the potential consequences of glomerulonephritis management without investigating the etiology of the underlying diseases, especially in patients from tropical and subtropical areas.
|Atypical presentation of pigmented villonodular synovitis: A case report|
Mohammed A AlDakhil, Abdulaziz M AlDakhil, Moyassar M Karami, Mohammed B Satti
Saudi Journal of Medicine and Medical Sciences 2019 7(1):44-46
Pigmented villonodular synovitis is a rare, disabling disease that usually presents in young adults. Here, the authors present a unique case of pigmented villonodular synovitis in a 60-year-old female diagnosed 20 years after the initial presentation. The patient presented with a complaint of knee pain consistent with osteoarthritis. Radiological investigations, including magnetic resonance imaging, only showed degenerative changes and were inconclusive to diagnose pigmented villonodular synovitis. Intraoperative macroscopic features of the synovium suggested pigmented villonodular synovitis, which was confirmed by histopathological examination. Histopathological examination, despite being the gold standard, was performed late in this case. The authors recommend histopathological confirmation of pigmented villonodular synovitis in all suspected cases, even with inconclusive radiological manifestations.
|Intralesional triamcinolone for treating mandibular langerhans cell histiocytosis: A case report and literature review|
Ahmed Almuzayyen, Wahbi Elhassan, Mousa Alabbadi
Saudi Journal of Medicine and Medical Sciences 2019 7(1):47-50
Langerhans cell histiocytosis is a rare condition ranging in manifestation from a focal boney lesion to multisystem involvement. Several treatment modalities have been proposed including curettage, low-dose radiotherapy, chemotherapy and intralesional injection of corticosteroids. These treatment options can be used as a single or combined approach. Prognosis depends on the extent of systemic involvement, and solitary lesions respond favorable to treatment. Here, the authors report a case of a 10-year-old male patient with Langerhans cell histiocytosis affecting his right posterior mandible that was successfully treated with intralesional injection of triamcinolone in multiple sessions. Complete recovery was confirmed clinically and radiographically in 18 months from the time of diagnosis.
