Aseptic Meningitis in Children: Analysis of 506 Cases

BACKGROUND: Non-polio human enteroviruses are the leading cause of aseptic meningitis in children. The role of enterovirus PCR for diagnosis and management of aseptic meningitis has not been fully explored. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective study was conducted to determine the epidemiological, clinical, and laboratory characteristics of aseptic meningitis and to evaluate the role of enterovirus PCR for the diagnosis and management of this clinical entity. The medical records of children who had as discharge diagnosis aseptic or viral meningitis were reviewed. A total of 506 children, median age 5 years, were identified. The annual incidence rate was estimated to be 17/100,000 children less than 14 years of age. Most of the cases occurred during summer (38%) and autumn (24%). The dominant clinical symptoms were fever (98%), headache (94%) and vomiting (67%). Neck stiffness was noted in 60%, and irritation in 46% of the patients. The median number of CSF cell count was 201/mm(3) with polymorphonuclear predominance (>50%) in 58.3% of the cases. Enterovirus RNA was detected in CSF in 47 of 96 (48.9%) children tested. Children with positive enterovirus PCR had shorter hospitalization stay as compared to children who had negative PCR or to children who were not tested (P = 0.01). There were no serious complications or deaths. CONCLUSIONS: Enteroviruses accounted for approximately one half of cases of aseptic meningitis. PCR may reduce the length of hospitalization and plays important role in the diagnosis and management of children with aseptic meningitis

Complications of Trans-oral Endoscopic Thyroidectomy Vestibular Approach: A Systematic Review

This review focuses on complications linked to trans-oral endoscopic thyroidectomy via vestibular approach (TOETVA) and aimed to elucidate the procedure’s initial safety profile. According to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA), Pubmed, Embase, and the Cochrane databases were screened till May 2021. Twenty-eight articles, nine cohorts and nineteen case series, met the inclusion criteria. Procedure-related complications were analyzed, the most important being hypoparathyroidism: transient (range=0.94-22.2%), permanent (range=1.33-2.22%), and recurrent laryngeal nerve injury: transient (range=1.9-8.8%) and permanent (range=0.59-1.42%). Surgical trauma related complications, the most prevalent being seroma, emphysema, and hematoma accounted for 2.91%. Null mortality was reported. Although current evolving experience indicates that TOETVA is safe and linked to acceptable complication rates, the method needs to be compared with the gold standard of traditional thyroidectomy in the context of sufficiently numbered cohorts and ultimately randomized controlled trials. © 2022 International Institute of Anticancer Research.

Pancreatic concentrations of cefepime in experimental necrotizing pancreatitis

To evaluate the penetration of cefepime in the inflamed pancreas, three doses of 50 mg/kg were administered intramuscularly at 8-h intervals after induction of acute necrotizing pancreatitis using intraperitoneal injection of DL-ethionine in 35 rabbits and in 33 controls. Animals were sacrificed and concentrations of cefepime were determined by a microbiological assay. Cefepime reached its peak concentrations 60 min after the last drug dose when mean values of 46.05 mug/ml, 22.34 mug/g and 34.74 mug/ml were found in serum, pancreas and bile, respectively, in rabbits with acute necrotizing pancreatitis and 45.19 mug/ml, 12.68 mug/g and 20.77 mug/ml respectively in controls. Tissue/serum ratios of cefepime were 0.48, 0.23, 0.15 and 0.09 at 60, 90, 120 and 180 min, respectively, after the last dose of cefepime in rabbits with acute necrotizing pancreatitis and 0.28, 0.18, 0.16 and 0.16, respectively at 60, 90, 120 and 180 min in controls. It is concluded that the administration of cefepime in rabbits with acute necrotizing pancreatitis resulted in pancreatic tissue levels well above the MIC(90)s of the common pathogens involved in pancreatic superinfection, so that its administration might be proposed for the therapy of superinfection following acute necrotizing pancreatitis in humans

Routine modified D2 lymphadenectomy performance in pT1-T2N0 gastric cancer

AIM: To evaluate routine modified D2 lymphadenectomy in gastric cancer, based on immunohistochemically detected skip micrometastases in level II lymph nodes. METHODS: Among 95 gastric cancer patients who were routinely submitted to curative modified D2 lymphadenectomy, from January 2004 to December 2008, 32 were classified as pN0. All level I lymph nodes of these 32 patients were submitted to immunohistochemistry for micrometastases detection. Patients in whom micrometastases were detected in the level I lymph node stations (n = 4) were excluded from further analysis. The level II lymph nodes of the remaining 28 patients were studied immunohistochemically for micrometastases detection and constitute the material of the present study. RESULTS: Skip micrometastases in the level II lymph nodes were detected in 14% (4 out of 28) of the patients. The incidence was further increased to 17% (4 out of 24) in the subgroup of T1-2 gastric cancer patients. All micrometastases were detected in the No. 7 lymph node station. Thus, the disease was upstaged from stage I A to I B in one patient and from stage I B to II in three patients. CONCLUSION: In gastric cancer, true R0 resection may not be achieved without modified D2 lymphadenectomy. Until D2+/D3 lymphadenectomy becomes standard, modified D2 lymphadenectomy should be performed routinely. © 2009 The WJG Press and Baishideng. All rights reserved

Association of dehydroepiandrosterone-sulfate with endothelial function in young women with polycystic ovary syndrome

Objective: The aim of this study was to assess non-invasively endothelial function of young women with polycystic ovary syndrome (PCOS) in comparison with healthy age-matched women and a group of young women with idiopathic hirsutism (IH). The possible role of metabolic and hormonal parameters on endothelial function was also examined. Design: Descriptive clinical trial. Methods: Fifty-six women, 27 with PCOS, 16 with IH and 13 healthy age-matched women were studied. Endothelial function of resistance arteries was assessed by venous occlusion plethysmography. Metabolic and hormonal parameters were estimated in this study population. Results: T he duration of reactive hyperemia (durRH) was shorter in PCOS group when compared with normal controls (63.75±13.33 s vs 113.18±20.92 s, P=0.036). A similar finding was observed when PCOS were compared with IH group (63.75±13.33 svs 105±17.20 s, P=0.05).The durRH did not differ between IH and control group (105±17.20 svs 113.18±20.92 s, ns). A significant positive linear correlation was found between the durRH and dehydroepiandrosterone-sulfate (DHEA-S) levels (r= +0.48, P=0.04) in the PCOS group. The basal insulin resistance index (HOMA) differed significantly between PCOS, IH and control groups. There was no significant correlation between durRH and HOMA index or testosterone levels in the PCOS group. Conclusions: Endot helial dysfunction may be an early sign of cardiovascular system abnormalities in young PCOS women. It is possible that increased DHEA-S levels may offer a cardioprotective advantage that attenuates the effects of cardiovascular risk factors that accompany PCOS. © 2006 Society of the European Journal of Endocrinology
