Aggressive Angiomyxoma of Inguinoscrotal Region Mimicking Inguinal Hernia: a Case Report

Abstract

Aggressive angiomyxoma (AAM) is a rare mesenchymal tumour of pelvis and perineum, almost exclusively occurring in females. We are reporting a case of a 53-year-old gentleman who presented with a long standing inguinoscrotal swelling misdiagnosed as inguinal hernia, for which he underwent incomplete excision at local hospital and then was referred to our centre for completion surgery.

AMMP-8 in correlation to caries and periodontal condition in adolescents—results of the epidemiologic LIFE child study

Abstract

Objectives

The suitability of a chairside aMMP-8 test in determination of periodontal inflammation and caries in adolescents was assessed. Secondly, the influence of orthodontic treatment on aMMP-8 test result was analyzed.

Materials and methods

Within the LIFE Child study, 434 adolescents (10 to 18 years) were included. Clinical dental examinations comprised caries experience (DMF/T-Index), signs of periodontal inflammation (probing pocket depth, PPD; community periodontal index of treatment needs; CPITN) at six index teeth and oral hygiene (OH). Information about orthodontic appliances (OA) and socioeconomic status (SES) were obtained by validated questionnaires. Test's sensitivity and specificity to detect periodontal inflammation and carious lesions were evaluated. The influence of OA on the test result was analyzed (multivariate model).

Results

No associations between age, gender, SES or OH, and test outcome were found (p > 0.05). Positive test results correlated to periodontal findings (CPITN, mean PPD; p < 0.001). However, for the detection of ≥ 1 site(s) with PPD ≥ 4 mm, the test's sensitivity and specificity were found to be 61 and 69%, respectively. Multivariate analysis revealed a higher probability for a positive test result in cases of fixed OA (odds ratio 5.02, 95% confidence interval 1.90–13.19). The test had no diagnostic value considering carious lesions.

Conclusions

The chairside aMMP-8 test does not reliably identify adolescents with periodontal inflammation. Positive test results were more frequent in case of OA.

Clinical relevance

The chairside aMMP-8 test is no appropriate tool to screen children and adolescents neither for periodontal inflammation nor for carious lesions.

The Asia-Pacific’s role in the emerging solar geoengineering debate

Abstract

Increasing interest in climate engineering in recent years has led to calls by the international research community for international research collaboration as well as global public engagement. But making such collaboration a reality is challenging. Here, we report the summary of a 2016 workshop on the significance and challenges of international collaboration on climate engineering research with a focus on the Asia-Pacific region. Because of the region's interest in benefits and risks of climate engineering, there is a potential synergy between impact research on anthropogenic global warming and that on solar radiation management. Local researchers in the region can help make progress toward better understanding of impacts of solar radiation management. These activities can be guided by an ad hoc Asia-Pacific working group on climate engineering, a voluntary expert network. The working group can foster regional conversations in a sustained manner while contributing to capacity building. An important theme in the regional conversation is to develop effective practices of dialogues in light of local backgrounds such as cultural traditions and past experiences of large-scale technology development. Our recommendation merely portrays one of several possible ways forward, and it is our hope to stimulate the debate in the region.

Nailfold videocapillaroscopy results in patients with rheumatoid arthritis

Abstract

We aimed to analyse the nailfold capillaryscopy findings morphologically and examine their relationship with disease activity and demographic characteristics in patients with rheumatoid arthritis. In accordance with the 2010 ACR/EULAR classification criteria, 201 patients diagnosed with Romatoiad artrit (RA) and 50 healthy controls were included. We analysed capillaroscopic abnormalities such asmegacapillaries, haemorrhages, ramifications and avascular areas in patients affected with rheumatoid arthritis. The findings in our study are as follows: in 45.77% of the RA patients, there were nonspecific capillaryscopy findings. When compared to control group, the incidence of tortuosity, dilated capillary and bushy capillary was higher in RA patients (p values, respectively, 0.110, 0.330, 0.440 and 0.516). In RA patients with Raynaud's phenomenon, the incidence of nonspecific capillaryscopy findings was higher. While there is a weak relationship between tortuosity and the duration of disease, no significant relation was detected between capillaryscopy findings and parameters such as RF, anti-CCP positivity and disease activity score (DAS28). When compared to controls, we have detected that RA patients have more nonspecific capillaryscopic findings. We could not find a relationship between nonspecific capillaryscopic findings and RA'a clinical findings and laboratory parameters. There is a need for a long-term wider-scale follow-up study to investigate whether there is a capillaryscopic pattern that can be correlated with RA's clinical findings.

Timeline of Intestinal Adaptation After Malabsortive Surgery: Effect of Luminal Nutrients, Biliopancreatic Secretion, and Glutamine Supplementation

Abstract

Background

The aim of this study was to study the process of intestinal adaptation in the three limbs of the small intestine after malabsorptive bariatric surgery: the biliopancreatic limb, the alimentary limb, and the common channel. These limbs are exposed to different stimuli, namely, gastrointestinal transit and nutrients in the alimentary limb, biliopancreatic secretions in the biliopancreatic limb, and a mix of both in the common channel. We also wished to investigate the effect of glutamine supplementation on the adaptation process.

Methods

Three types of surgery were performed using a porcine model: biliopancreatic bypass (BPBP), massive (75%) short bowel resection as the positive control, and a sham operation (transection) as the negative control. We measured the height and width of intestinal villi, histidine decarboxylase (HDC) activity, and amount of HDC messenger RNA (mRNA) (standard diet or a diet supplemented with glutamine).

Results

An increase in HDC activity and mRNA expression was observed in the BPBP group. This increase coincided with an increase in the height and width of the intestinal villi. The increase in villus height was observed immediately after surgery and peaked at 2 weeks. Levels remained higher than those observed in sham-operated pigs for a further 4 weeks.

Conclusions

The intestinal adaptation process in animals that underwent BPBP was less intense than in those that underwent massive short bowel resection and more intense than in those that underwent transection only. Supplementation with glutamine did not improve any of the parameters studied, although it did appear to accelerate the adaptive process.

Effect of recent spinal cord injury on the OPG/RANKL system and its relationship with bone loss and the response to denosumab therapy

Abstract

Summary

There is marked bone loss after spinal cord injury (SCI); however, its pathogenesis and clinical management remain unclear. The increased circulating levels of receptor activator of nuclear factor kB ligand (RANKL) associated with bone loss shortly after SCI and the prevention of bone loss with denosumab treatment suggest a contributory role of RANKL in SCI-induced osteoporosis.

Introduction

Bone turnover and bone loss are markedly increased shortly after SCI. However, the pathogenesis and clinical management of this process remain unclear, especially the role of the osteoprotegerin (OPG)/RANKL system in this disorder. The aim of this study was to analyze serum levels of OPG and RANKL in bone loss associated with recent SCI and the effect of denosumab treatment on these mediators.

Methods

Twenty-three males with recent complete SCI were prospectively included. Serum OPG and RANKL levels, bone turnover markers (PINP, bone ALP, CTX), and bone mineral density (BMD) were assessed at baseline, at 6 months of follow-up, prior to initiating denosumab, and 6 months after treatment. The results were compared with a healthy control group.

Results

At baseline, SCI patients showed higher RANKL levels vs. controls which were correlated with days-since-SCI and total hip BMD loss at 6 months. OPG levels were similar to controls at baseline. After denosumab treatment, OPG showed no changes, whereas RANKL levels became undetectable in 67% of patients. Patients with undetectable RANKL during treatment showed better response in femoral BMD and bone markers vs. patients with detectable RANKL at 6 months of denosumab. Increased parathormone (PTH) levels during treatment were negatively correlated with RANKL changes.

Conclusions

RANKL levels are increased after SCI and related to BMD loss at the proximal femur, becoming undetectable after denosumab treatment. The effect of denosumab on preventing sublesional bone loss, especially in patients with undetectable levels during treatment, suggests a contributory role of RANKL in this process.
