xlomafota13 shared this article with you from Inoreader Migration of Ventriculoperitoneal Shunt to Uterus In A Child: A Case Report Via leak of cerebrospinal fluid J Pediatr Adolesc Gynecol. 2021 Nov 26:S1083-3188(21)00343-0. doi: 10.1016/j.jpag.2021.11.004. Online ahead of print. ABSTRACT BACKGROUND: Ventriculo-peritoneal shunt (VPS) is usually placed inside the peritoneal cavity for cerebrospinal fluid drainage. Rarely, it can migrate to various pelvic visceral organs. Inside the pelvis, the distal end of the shunt can perforate anywhere from the uterus or adnexa to the vulva and migration through the uterus is extremely rare. CASE: A three-and-a-half-year-old girl presented with CSF leak through the vagina following uterine perforation by VPS. The diagnosis was made with an ultrasound. Her symptoms resolved following revision surgery. CONCLUSION: In a patient with a VPS in situ, presenting with a watery fluid leak through vagina, perforation of fornix or uterus must always be kept in mind. Timely diagnosis and intervention can result in the prevention of complications. PMID:34843976 | DOI:10.1016/j.jpag.2021.11.004 View on the web Inoreader. Take back control of your news feed.

Geographic disparities in head and neck cancer survival

xlomafota13 shared this article with you from Inoreader Geographic disparities in head and neck cancer survival in Upstate New York 2011–2019 Via Head & Neck Abstract Purpose To examine the association between distance to care-center and urban–rural residence on 5-year overall survival (OS) from head and neck cancer (HNC). Materials and methods Five-year OS was retrospectively measured from date of initial diagnosis for patients with HNC treated at a single tertiary care center. Distances were calculated based on ZIP code of patient's residence and care center. Multilevel Weibull regression was used to adjust for confounders and identify disparities in 5-year all-cause mortality. Results A total of 670 patients included in study. Multivariable analysis revealed older age or late-stage cancer at diagnosis, and HPV negative status were associated with poorer OS. Patients residing in isolated small rural town (HR = 2.20, p = 0.015) or small rural town (HR = 2.07, p = 0.015) had lower OS. Distance to care center was not associated with OS (HR = 0.996, p = 0.11). Conclusions Greater rurality was associated with poorer OS among HNC patients in Upstate New York.

xlomafota13 shared this article with you from Inoreader Heads up reconstructive microsurgery: Utilisation of the three-dimensional microscope in microvascular procedures Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 15:S1748-6815(21)00575-1. doi: 10.1016/j.bjps.2021.11.036. Online ahead of print. ABSTRACT BACKGROUND: Since the earliest use of microscopes in surgery, several modifications have been made to improve the ergonomics of movement and posture, increase the resolution, and expand the visual field. The three-dimensional microscopes are latest innovation in this field. Despite the wider use of 3D microscopes in other specialities, their use in the reconstructive microsurgery in the United Kingdom is still limited. Reconstructive microsurgeons are highly skilled surgeons that are trained to operate utilising the microscope for long hours. This poses an occupational risk with a specific pattern of work-related conditions. AIMS AND METHODS: We aim in this report to demonstrate our experience utilising 3D microscopes in small cohort of patients matched to a control of patients operated utilising the traditional microscopes. Patients were matched by age, comorbidities, oncologic procedures. This was complemented by a survey completed by the operating surgeons. RESULTS: Nine patients were included in each group. There was no significant difference in operative or ischemia time and no significant post-operative complications in both groups. The surgeons reported better ergonomics, improved staff engagement, and a better teaching experience when utilising the 3D microscopes compared to traditional microscopes. CONCLUSION: The utilisation of the 3D microscopes in reconstructive microsurgery has shown to provide comfort, improve ergonomics of movement and posture without significant clinical implications in this series.

The effects of cigarette smoking and nicotine on the therapeutic potential of mesenchymal stem cells

xlomafota13 shared this article with you from Inoreader The effects of cigarette smoking and nicotine on the therapeutic potential of mesenchymal stem cells Via Cellular and Molecular Biology Histol Histopathol. 2021 Nov 30:18400. doi: 10.14670/HH-18-400. Online ahead of print. ABSTRACT Due to their immunoregulatory properties and capacity for multi-lineage differentiation, mesenchymal stem cells (MSCs) have been used as new therapeutic agents in regenerative medicine. Numerous lifestyle habits and behavioral risk factors may modulate metabolic and cell growth signaling pathways in MSCs, affecting their phenotype and function. Accordingly, identification of these factors and minimization of their influence on viability and function of transplanted MSCs may greatly contribute to their better therapeutic efficacy. A large number of experimental and clinical studies have demonstrated the detrimental effects of cigarette smoke and nicotine on proliferation, homing, chondrogenic and osteogenic differentiation of MSCs. Cigarette smoke down-regulates expression of chemokine receptors and modulates activity of anti-oxidative enzyme s in MSCs, while nicotine impairs synthesis of transcriptional factors that regulate the cell cycle, metabolism, migration, chondrogenesis and osteogenesis. In this review article, we summarize current knowledge about molecular mechanisms that are responsible for cigarette smoke and nicotine-dependent modulation of MSCs' therapeutic potential.

Association Between Insurance Type and Outcomes of Reconstructive Head and Neck Cancer Surgery

xlomafota13 shared this article with you from Inoreader Association Between Insurance Type and Outcomes of Reconstructive Head and Neck Cancer Surgery Via The Laryngoscope Objectives/Hypothesis Although the benefits of expanding health insurance coverage are clear, there are limited studies comparing the different types of insurance. This study aims to determine the association between insurance type and outcomes in patients with head and neck cancer undergoing reconstructive surgery in the United States. Methods Population-based cross-sectional study of the 2012–2014 National Inpatient Sample. We identified 1,314 patients with head and neck cancers undergoing tumor ablative surgery followed by pedicled or free flap reconstruction of oncologic defects. Insurance type was classified as private, Medicare, Medicaid, self-pay, or other. The primary outcome was extended length of stay (LOS), defined as greater than 14 days, which represented the 75th percentile of the study sample. Secondary outcomes included acute medical complications, surgical complications, morbidities, and costs. Analyses were adjusted for gender, geographic location, and various medical comorbidities. Results In univariate analysis, insurance type was associated with extended LOS (P = .001), medical complications (P = <.001), and mortalities (P = .020). After controlling for other covariates in the multivariate analysis, compared to private insurance, Medicare and Medicaid were both associated with significantly higher odds of extended LOS (adjusted odds ratio [OR] [95% confidence interval (CI)] = 1.73 [1.09–2.76] and 2.22 [1.38–3.58], respectively). Medicare was associated with significantly higher odds of medical complications, but Medicaid was not (adjusted OR [95% CI] = 1.53 [1.02–2.31] and 1.64 [0.97–2.78], respectively). Conclusions Medicaid and Medicare were independently associated with extended LOS after reconstructive head and neck cancer surgery. Medicare was associated with higher rates of medical complications. Efforts to address LOS should target care planning and coordination.

Diagnosis of upper airways collapse in moderate-to-severe OSAHS patients: a comparison between drug-induced sleep endoscopy and the awake examination

xlomafota13 shared this article with you from Inoreader Diagnosis of upper airways collapse in moderate-to-severe OSAHS patients: a comparison between drug-induced sleep endoscopy and the awake examination 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 Nov 28. doi: 10.1007/s00405-021-07184-8. Online ahead of print. ABSTRACT PURPOSE: Compare awake evaluation (modified Mallampati score-MMs, Müller maneuver-MM) to drug-induced sleep endoscopy (DISE) findings according to NOHL (nose-oropharynx-hypopharynx-larynx) classification in moderate-to-severe OSAHS patients. METHODS: 43 moderate-to-severe OSAHS patients referred to our ENT department were enrolled over a 2-year period. In this observational prospective study, each patient was evaluated by the same ENT team both in wakefulness and during pharmacologically induced sleep. Level and severity of the obstruction were described. RESULTS: The comparison of degree of collapsibility was statistically significative only at hypopharyngeal level: 41.8% of the patients showed a hypopharyngeal obstruction in wakefulness whereas 88.3% in DISE (p = 0.000). Laryngeal level was found in 18.6% patients dur ing awake examination, conversely DISE demonstrated laryngeal obstruction in 4.6%. DISE identified significantly higher incidence of multilevel collapses (p = 0.001). However, the incidence of oropharyngeal obstruction in patients classified as MMs I and II was significantly higher in DISE compared to MM (p = 0.021). CONCLUSION: DISE is the best predictor of hypopharyngeal obstruction, whereas MM underestimates the severity of the collapse at this level. DISE is more reliable than MM to identify the obstruction in patients with MMs score I and II. PMID:34839405 | DOI:10.1007/s00405-021-07184-8 View on the web Inoreader.

A retrospective analysis of rates of allergic reaction to Patent V blue dye used in sentinel lymph node biopsies for melanoma

xlomafota13 shared this article with you from Inoreader A retrospective analysis of rates of allergic reaction to Patent V blue dye used in sentinel lymph node biopsies for melanoma Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 14:S1748-6815(21)00570-2. doi: 10.1016/j.bjps.2021.11.023. Online ahead of print. ABSTRACT Sentinel lymph node biopsies are a well-established component of the assessment and treatment pathway for patients with cutaneous melanoma in the UK. Commonly utilised techniques involve the use of blue dye which has an established risk of inducing allergic reactions in patients. Such reactions can be life-threatening, and this risk is important to highlight to patients. We conducted a retrospective review of all patients who had undergone this procedure at our melanoma centre in Cambridge, UK. From a group of 715 patients who received blue dye as part of the procedure, six patients suffered an allergic reaction (0.84%) with one of these treated as anaphylaxis. Our incidence of anaphylaxis is almost ten times greater than that reported in the NAP6 report led by the National Institute of Academic Anaesthesia and significantly higher than reported by others. We propose several reasons why our results differ from previous estimates. This study has focused only on patients undergoing a sentinel node procedure for melanoma, others have focused on such procedures performed on patients with breast cancer and some have combined the two. The administration technique, volume and anatomical distribution of disease all differ significantly from melanoma, possibly influencing rates and severity of allergic reactions.

Ectopic thymic tissue in subglottis of children: evaluation and management

xlomafota13 shared this article with you from Inoreader Ectopic thymic tissue in subglottis of children: evaluation and management Via Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial Braz J Otorhinolaryngol. 2021 Nov 5:S1808-8694(21)00179-8. doi: 10.1016/j.bjorl.2021.10.001. Online ahead of print. ABSTRACT OBJECTIVES: Ectopic thymic tissue in the subglottis is an extremely rare disease that causes airway obstruction. Few cases reported were accurately diagnosed before surgery. METHODS: A case of a 2-year-old boy with airway obstruction caused by a left subglottic mass was reported. The presentation of radiological imaging, direct laryngoscopy and bronchoscopy, pathology, and surgical management were reviewed. An extensive search in PubMed, EMBASE, Web of Science, Google Scholar, and EBSCO of English literature was performed without a limit of time. RESULTS: Besides our case, only six cases were reported since 1987. The definitive diagnosis on these patients were made with the findings of pathology, of which, five were ectopic thymus and two were ectopic thymic cysts. Our case was the only one with a cor rect suspicion preoperatively. Four cases underwent open surgical resection, and two cases underwent microlaryngeal surgery, while one deceased after emergency tracheostomy. No recurrences were found by six patients during the follow-up after successful treatments. CONCLUSION: Ectopic thymus is a rare condition, infrequently considered in the differential diagnosis of subglottic masses. Modified laryngofissure may be an effective approach to removing the subglottic ectopic thymus and reconstructing the intact subglottic mucosa.

Clinical and Microbiological Factors Associated With Abscess Formation in Adult Acute Epiglottitis

xlomafota13 shared this article with you from Inoreader Clinical and Microbiological Factors Associated With Abscess Formation in Adult Acute Epiglottitis Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Nov 28:34894211051817. doi: 10.1177/00034894211051817. Online ahead of print. ABSTRACT OBJECTIVES: To evaluate clinical and microbiological findings that are correlated with abscess formation in adult acute epiglottitis (AE). METHODS: We reviewed 140 cases of adult AE. Demographic, clinical, imaging, and microbiological findings are analyzed for all patients with AE in comparison to those with epiglottic abscess (EA). RESULTS: A tot al of 113 patients presented with AE and 27 presented or progressed to EA (19.3%). Age, sex, seasonality, smoking, body mass index (BMI), and comorbidities were statistically insignificant between the 2 groups. Muffled voice (P < .013), respiratory distress (P < .001), and pre-existence of epiglottic cyst (P < .001) are symptoms and signs connected with abscess formation. A total of 120 patients were treated conservatively. Surgical treatment was performed on 20 patients with EA. About 72 out of 80 cultures revealed monomicrobial infection. Mixed flora was isolated in 8 patients with EA. Streptococcus was isolated in 51 out of 80 positive cultures (64%). Haemophilus Influenza (Hib) was not isolated in any sample. EA and mixed flora relates to a higher rate of airway intervention (P < .001). CONCLUSION: A high level of suspicion for abscess formation is required if clinical examination reveals dyspnea, muffled voice, or an epiglottic cyst in adult with AE. The existence of EA doubles the duration of hospitalization. EA is typically found on the lingual surface of the epiglottis. Supraglottic or deep neck space expansion should be treated surgically. EA is associated with a mixed flora and a higher rate of airway obstruction. Streptococcus is discovered to be the most common pathogen.

The importance of vascular epithelial growth factor (VEGF) and inducible nitric oxide synthase (INOS) in rhinitis medicamentosa pathogenesis: An experimental rat model study

xlomafota13 shared this article with you from Inoreader The importance of vascular epithelial growth factor (VEGF) and inducible nitric oxide synthase (INOS) in rhinitis medicamentosa pathogenesis: An experimental rat model study Via Cellular and Molecular Biology Histol Histopathol. 2021 Nov 29:18399. doi: 10.14670/HH-18-399. Online ahead of print. ABSTRACT OBJECTIVE: Our aim in this study is to reveal the expression of Vascular Endothelial Growth Factor (VEGF) and Inducible Nitric Oxide Synthase (iNOS) in the pathogenesis of rhinitis medicamentosa (RM), which occurs as a result of the overdose and long-term use of topical nasal decongestants. METHODS: In this study, 24 Wistar albino rats were divided into two groups as experimental and control groups. In the experimental group, 50 µl of 0.05% oxymetazoline (iliadin® merck) was applied intranasally to each nostril three times a day for 2 months with the help of a micropipette. 50 µl saline was applied to the control group. At the end of the second month, the rats were examined. RM was detected in the experimental group. Then the nasal tissues of the rats were removed and fixed with 10% phosphate buffered neutral formaldehyde (pH=7.4). Nasal tissues were decalcified in Morse's solution (10% sodium citrate and 22.5% formic acid). Histopathological evaluations of the preparations were stained using Masson Trichrome (TCM) and Hematoxylin Eosin (H&E) techniques and immunohistochemical examinations of the preparations were stained with VEGF and iNOS antibodies and photographed using the Leica DM6000B microscope and the Leica Application Suite Program. RESULTS: In the RM group, we found a significant increase in VEGF and iNOS expression in the nasal mucosa compared to the control group (p<0.001). We also observed the main histopathological changes in the nasal mucosa under a light microscope, including squamous metaplasia in the epithelium of the tunica mucosa, submucosal perivascular edema and degeneration of the submucosal glands. CONCLUSIONS: According to these results, increased expression levels of VEGF and iNOS play an important role in rebound swelling in RM pathogenesis.
