ABSTRACT BACKGROUND: CSF rhinorrhea is a type of CSF leakage caused by an aseptic abnormal passage between the subarachnoid space and the adjacent sinus and nasal cavity due to a cranial dural defect. At present, the value of computed tomography cisternography (CTC) in locating CSF rhinorrhea has been widely recognized, and magnetic resonance hydrography (MRH), as a heavy T2-weighted water imaging, plays a pivotal role in showing the location of the leak. In this paper, we retrospectively summarize the imaging manifestations seen at our hospital of patients with clinically confirmed CSF rhinorrhea at the skull base and evaluate the diagnostic value of different imaging methods in the localization of CSF rhinorrhea by means of preoperative imaging analysis using CTC and MRH. METHODS: Fifty-five patients with CSF rhinorrhea admitted to our department from October 2016 t o January 2021 were retrospectively analyzed. The patients' conventional CT, CTC, and MRH imaging data were compared, and the location of the leak determined preoperatively matched the location of the leak found during surgery. Moreover, there was no recurrence during the follow-up period of 4 months to 3 years. RESULTS: There were statistically significant differences between the diagnostic positivity rate of CTC and spiral CT (χ2=16.755, P<0.00), and between the diagnostic positivity rate of cranial MRH and spiral CT (χ2=6.338, 6.338=0.01), and no statistically significant difference between the diagnostic positivity rate of CTC and cranial MRH (χ2=2.625, P=0.1). CONCLUSIONS: The combined use of imaging techniques has important practical significance for the proper treatment and prognostic evaluation of CSF rhinorrhea. CTC has the highest positive rate for the diagnosis of CSF rhinorrhea, followed by MRH, while spiral CT is safer. CTC and MRH can promote the diag nostic rate in determining the location of CSF rhinorrhea, and selective combined application can be an important guide to surgery.

Prognostic Significance of a Scoring System Combining p16, Smoking, and Drinking Status in a Series of 131 Patients with Oropharyngeal Cancers

xlomafota13 shared this article with you from Inoreader Prognostic Significance of a Scoring System Combining p16, Smoking, and Drinking Status in a Series of 131 Patients with Oropharyngeal Cancers Via International Journal of Otolaryngology Background. Tobacco and alcohol are two main risk factors associated with head and neck squamous cell carcinoma (HNSCC). Studies showed that human papillomavirus (HPV) plays a role in the etiology of this cancer. HPV-positive oropharyngeal squamous cell carcinoma (OSCC) patients present in general a better response to conventional therapy and better overall survival (OS). However, OSCC is a heterogeneous disease regarding treatment. This study aimed to identify more effective prognostic factors associated with a poor clinical outcome for OSCC patients to improve treatment selection. Materials and Methods. OSCC patients diagnosed between 2007 and 2017, in two Belgian hospitals, were included. Demographic and clinicopathologic data were extracted from medical records. HPV status was determine d through p16 immunohistochemistry. Univariable and multivariable Cox proportional hazard regression analyses allowed to identify variables prognostic for OS and recurrence-free survival (RFS). Kaplan–Meier survival curves have been assessed for survival. Results. The study included 131 patients. Statistics showed that monotherapies were significantly associated with a shorter OS; p16 overexpression was significantly associated with a weak consumption of tobacco or alcohol, and a high p16 expression was significantly associated with both longer RFS and OS. The study validated that tobacco and alcohol consumption were significantly correlated with poorer RFS and poorer OS. Only p16 expression trended to be significant for RFS when compared to smoking and drinking habits, while p16 upregulation and alcohol use were both vital for OS indicating that p16 is an independent and significant prognostic factor in OSCC patients. Finally, a scoring system combining p16, tobacco, and alcohol status was defined and was significantly associated with longer RFS and longer OS for nonsmoker and nondrinker p16-positive OSCC patients. Conclusions. This study confirmed that the overexpression of the p16 protein could be viewed as a factor of good prognosis for RFS and OS of OSCC patients. The prognostic significance of a scoring system combining p16 expression, smoking, and drinking status was evaluated and concluded to be a more effective tool to determine therapeutic orientations based on the risk factors for better treatment relevance and survival.

Long-term aesthetics, patient-reported outcomes, and auricular sensitivity after microtia reconstruction: A systematic review

xlomafota13 shared this article with you from Inoreader Long-term aesthetics, patient-reported outcomes, and auricular sensitivity after microtia reconstruction: A systematic review Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Aug 19:S1748-6815(21)00379-X. doi: 10.1016/j.bjps.2021.08.004. Online ahead of print. ABSTRACT BACKGROUND: Auricular reconstruction for microtia is most frequently performed using autologous costal cartilage (ACC) or porous polyethylene (PPE) implants. Short-term results are generally promising, but long-term results remain unclear. Long-term outcomes were explored in this systematic review, and minimal reporting criteria were suggested for future original data studies. METHODS: A systematic literature search was conducted in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from inception through October 14, 2020. Articles on auricular reconstruction in patients with microtia using ACC or PPE were included if postsurgical follow-up was at least 1 year. Outcome reporting was split into separate publications, and results on complications were reported previously. This publi cation focused on long-term aesthetic, patient-reported, and sensitivity outcomes. RESULTS: Forty-one publications reported on these outcomes. Both materials led to aesthetically pleasing results and high rates of patient satisfaction. ACC frameworks grew similarly to contralateral ears, and the anterior surface of auricles regained sensitivity. Furthermore, postoperative health-related quality of life (HRQoL) outcomes were generally good. Data synthesis was limited due to considerable variability between studies and poor study quality. No conclusions could be drawn on the superiority of either method due to the lack of comparative analyses. CONCLUSION: Future studies should minimally report (1) surgical efficacy measured using the tool provided in the UK Care Standards for the Management of Patients with Microtia and Atresia; (2) complications including framework extrusion or exposure, graft loss, framework resorption, wire exposure and scalp/auricular scar complication s and (3) HRQoL before and after treatment using the EAR-Q patient-reported outcome measure (PROM).

Online ahead of print. ABSTRACT OBJECTIVE: Review literature data on the coblation method in otorhinolaryngology. MATERIALS AND METHODS: All materials from our study are published in peer-reviewed journals. The review is PubMed generated. In our clinic, 20 patients with bilateral paralytic laryngeal stenosis underwent cold-plasma posterior arytenoidcordotomy with Coblator II. RESULTS: The analysis of the high-energy techniques currently applied in otorhinolaryngology shows the benefits of coblation due to the effect of lower temperatures on tissues. Patients subjectively reported improved breathing on day 10 with a closed coblation tracheostoma; after 3-6 months everyone underwent successful decannulation with plastic surgery of the cutaneous-tracheal fistula. Lately, the operated vocal fold was in the abduction position and the lumen of the glottis in the posterior third was 7-8 mm. Compensation of vocal function in the long-term postoperative period was achieved by patients due to long-term orthophonic training and the development of a vestibuloscapular phonation mechanism. CONCLUSION: The advantages of coblation are mainly minimal trauma to the surrounding tissues, convenient resection, the ability to perform complete hemostasis at one time, and easier postoperative period for the patient.

LINC00937 suppresses keloid fibroblast proliferation and extracellular matrix deposition by targeting the miR-28-5p/MC1R axis

xlomafota13 shared this article with you from Inoreader LINC00937 suppresses keloid fibroblast proliferation and extracellular matrix deposition by targeting the miR-28-5p/MC1R axis Via Cellular and Molecular Biology Histol Histopathol. 2021 Aug 23:11372. doi: 10.14670/HH-18-372. Online ahead of print. ABSTRACT Long noncoding RNAs (lncRNAs) are the most recently discovered class of noncoding RNAs. LncRNAs play a crucial role in multiple disorders. However, the role and mechanism of action of lncRNAs in keloids remain unclear. Here, qRT-PCR and western blotting assays were performed to determine the expression of genes and proteins, respectively. MTT assays were carried out to measure the proliferation of keloid fibroblasts. In addition, a luciferase activity assay was conducted to investigate the relationships between LINC00937 and miR-28-5p and between miR-28-5p and MC1R. The results showed that LINC00937 and MC1R were decreased, whereas miR-28-5p was increased in keloid tissues. LINC00937 overexpression in keloid fibroblasts could repress the extracellular matrix (ECM) deposition and cell proliferation and promote MC1R expression. Moreover, high expression of miR-28-5p and low expression of LINC00937 were detected in keloid fibroblasts. We further showed that LINC00937 promoted MC1R expression by sponging miR-28-5p. Finally, our data indicated that LINC00937 inhibited the ECM deposition and proliferation of keloid fibroblasts by inhibiting miR-28-5p and facilitating MC1R expression. Overall, LINC00937 suppressed the ECM deposition and proliferation of keloid fibroblasts by acting as an miR-28-5p sponge and promoting MC1R expression. Our data suggested that LINC00937 is a potential target for keloid treatment. PMID:34486677 | DOI:10.14670/HH-18-372 View on the web Inoreader. Take back control of your news feed.

Cochlear implantation under local anesthesia in 117 cases: patients' subjective experience and outcomes

xlomafota13 shared this article with you from Inoreader Cochlear implantation under local anesthesia in 117 cases: patients' subjective experience and outcomes Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Sep 6. doi: 10.1007/s00405-021-07061-4. Online ahead of print. ABSTRACT PURPOSE: To report the outcomes and the patients' subjective experience of cochlear implantation (CI) performed under local anesthesia (LA). To describe a new form of intraoperative cochlear monitoring based on the patients subjective sound perception during CI. METHODS: In this retrospective case-cohort study, 117 patients underwent CI under LA with (n = 58) or without conscious sedation (n = 59). Included were primarily elderly patients with elevated risks for general anesthesia and recently patients with residual hearing eligible for electro-acoustic stimulation (EAS) (n = 27), in whom hearing could be monitored during the electrode insertion. A 500 Hz test tone was presented and the patient reported of subjective changes in loudness, leading to a modification of the insertion. A questionnaire was sent to all patients in whi ch they assessed their subjective experience. RESULTS: All patients were successfully operated under LA without the need to intraoperatively convert to general anesthesia. 90% of the patients reported that the surgery was a positive experience. The vast majority, 90% of patients were satisfied with the overall treatment and with intraoperative pain management and 84% of the patients would opt for local anesthesia again. Cochlear monitoring by the patients' subjective sound perception enabled for atraumatic insertions as all EAS patients could hear the test tone up to the end of the surgery. CONCLUSIONS: CI under LA was well tolerated and recommended by the vast majority of patients. In addition, it offers the possibility to monitor the patients' hearing during the electrode insertion, which may help to prevent insertion trauma.
