Atrakuryum, rokuronyum, mivakuryum, sisatrakuryum, pankuronyum ve vekuronyumda Escherichia coli üremesi

Amaç: Biz çalışmamızda atrakuryum, rokuronyum, mivakuryum, sisatrakuryum, pankuronyum ve vekuronyumun Escherichia coli üremesi üzerine olan etkinliğini araştırdık. Hastalar ve Yöntemler: Patojen bakteri, atrakuryum, rokuronyum, mivakuryum, sisatrakuryum, pankuronyum ve vekuronyum ile 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, ve 24 saat oda sıcaklığında temas ettirildi. Bulgular: Escherichia coli ortalama koloni sayısı rokuronyumda istatiksel anlamlı olarak atrakuryum, mivakuryum, sisatrakuryum, pankuronyum ve vekuronyumdan daha düşük saptandı (sırasıyla p=0.002, 0.000, 0.000, 0.001, ve 0.002). Atrakuryum, mivakuryum, sisatrakuryum, pankuronyum ve vekuronyumda ortalama koloni sayısı açısından anlamlı fark saptanmadı (p<0.05). Sonuç: Rokuronyum, diğer nöromusküler kas gevşetici ajanlardan daha kuvvetli antimikrobiyal etki gösterdi.Objectives: We studied in vivo growth of Escherichia coli in atracurium, rocuronium, mivacurium, cisatracurium, pancuronium, and vecuronium. Patients and Methods: The pathogen was exposed to atracurium, rocuronium, mivacurium, cisatracurium, pancuronium and vecuronium for 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24 h at room temperature, respectively. Results: The mean colony counts of Escherichia coli after exposure to rocuronium was significantly lower than the counts after exposure to atracurium, mivacurium, cisatracurium, pancuronium and vecuronium (p=0.002, 0.000, 0.000, 0.001, and 0.002, respectively). No significant difference was found with respect to the mean colony counts with atracurium, mivacurium, cisatracurium, pancuronium and vecuronium (p&lt;0.05). Conclusion: Rocuronium had more powerful antimicrobial effects than the other neuromuscular agents

Intraductal Neoplasms of the Pancreas: An Update

With improvements in imaging to detect silent pancreatic lesions and increases in the number of centers now performing pancreatic surgery, more surgeries have been performed for indications other than invasive carcinoma. This has enormously added to our knowledge of the intraductal neoplasms of the pancreas. In addition, our understanding of the genetics of these lesions has expanded with the introduction of routine molecular genetic analyses. In this review, we provide an update into the most common intraductal neoplasms, namely intraductal papillary mucinous neoplasm and intraductal tubulopapillary neoplasm. We first focus on their clinicopathologic and molecular features of relevance to the practicing pathologist and then discuss their differential diagnoses

IgA Nephropathy and Psoriasis in a Child

Ig A nephropathy is the most common primary glomerulonephritis worldwide. Painless macroscopic hematuria is frequent in children and often coincides with infections of the upper respiratory tract and/ or digestive system. The distinctive carbohydrate side chains of IgA1 molecules play an important role in the pathogenesis of IgA nephropathy. Definitive diagnosis of IgA nephropathy requires evaluation of a renal biopsy specimen. Psoriasis is also a common childhood chronic skin disease with changes in epidermal differentation and proliferation. There are also a few literature reports on the co-existence of IgA nephropathy and psoriasis mainly in adult patients. Herein, we report a child with psoriasis who was diagnosed as Ig A nephropathy after periods of painless hematuria

Epithelial inclusions in the gallbladder: cytoisospora belli organisms or degenerative intracytoplasmic pas-positive hyaline globules

Background: Lai et al. reported 18 cases of Cystoisospora belli in the gallbladders (GBs), detected incidentally in 0.5% ofimmunocompetent patients (PMID: 27158759). However, a recent molecular study failed to confirm this observation at molecular level(PMID: 30020094). Although Lai et al. indicated that Cystoisospora in the GB is quiescent in immunocompetent patients, this diagnosisnevertheless has major implications, resulting in extensive patient workup for undetected immunosuppression.United States & Canadian Academy of Patholog

Follicular cholecystitis: Reappraisal of incidence, definition, and clinicopathologic associations in an analysis of 2550 cholecystectomies

Context.Follicular cholecystitis (FC) is a poorly characterized entity.Objective.To determine its frequency/clinicopathologic associations.Design.A total of 2550 cholecystectomy specimens were examined. Two hundred three of these were consecutive routine cholecystectomies submitted entirely for microscopic examination to determine the relative frequency of incidental pathologies in gallbladders (GBs). The remainder had representative sampling. Underlying conditions were nonobstructive pathologies (1270 nonspecific cholecystitis), obstructive (62 distal biliary tract tumors, 35 primary sclerosing cholangitis, and 31 autoimmune pancreatitis), and neoplastic (n = 949). FC was defined as 3 distinct lymphoid follicles (LFs)/centimeter.Results.In the GBs totally submitted for microscopic examination, the true frequency of FC was found to be 2.5% (5/203), and in the representatively sampled group, it was 1.9%, with similar frequencies in nonobstructive, obstructive, and neoplastic cases (2.3%, 3.1%, and 1.3%, respectively, P = .77). When the 39 FC in nonneoplastic GBs contrasted with ordinary chronic cholecystitis, they were associated with older age (68 vs 49 years, P < .0001), similar gallstone frequency (68 vs 81%), female/male ratio (2.7 vs 2.6), and wall thickness (4 mm for both). None had lymphoma/parasites/Salmonella infection. Of 17 cases who had undergone gastric biopsy, 5 had chronic gastritis (2 with Helicobacter pylori). Microscopically, the LFs were the main inflammatory process often with minimal intervening inflammation. IgG4-positive plasma cell density was low (<10/high-power field) in 21/24(87.5%) cases.Conclusions.Follicular cholecystitis is seen in 2% of cholecystectomies, typically in significantly older patients, suggesting a deranged immune response. A third of the patients reveal biopsy-proven gastritis. FC does not seem to be associated with autoimmunity, lymphoma, or obstructive pathologies

Poorly cohesive cell (diffuse-infiltrative/signet ring cell) carcinomas of the gallbladder: Clinicopathological analysis of 24 cases identified in 628 gallbladder carcinomas

WOS: 000394069800004PubMed ID: 27666767Signet ring cell carcinoma is an extremely rare type of gallbladder carcinoma: In the gastrointestinal system, carcinomas with single-cell or cord-like infiltration, previously called "diffuse-infiltrative" type or "signet ring cell," are now designated as "poorly cohesive cell" (PCC) type (regardless of with/without signet ring cells) in the World Health Organization 2010 classification. Six hundred twenty-eight primary invasive gallbladder carcinomas were reviewed for the PCC pattern. Twenty-four cases in which classical PCC pattern constituted greater than 50% of the tumor were included in the study. The mean age was 63 (range, 44-84) years. A strong female predominance was present (female/male ratio, 6.3 versus 3.9 for all gallbladder carcinomas). Most cases (79%) had advanced carcinoma (pT3+) in comparison with 51% of usual carcinomas (P < .01). All cases (100%) showed at least focal signet ring morphology (intracytoplasmic mucin), and this was predominant in 50%. Twelve cases (50%) demonstrated a focal invasive glandular component of the usual type. Overlying focal high-grade dysplasia was identified in 11 (46%). Due to block loss, immunohistochemistry could be performed in only 5 cases and revealed a profile similar to upper gastrointestinal carcinomas CK7++/CK20-+/CDX2+-/p53+. E-cadherin was decreased in the PCC component of all cases. The clinical course appeared to be more aggressive than ordinary gallbladder. carcinomas, with median survival of 3.3 months versus 11.8 months, which did not reach statistical significance (P = .06 by log-rank test). In conclusion, PCC carcinoma originating in the gallbladder should be kept in mind for the differential diagnosis of disseminated poorly differentiated carcinomas in the abdomen
