RESUMO
Existing literature about peritoneal tuberculosis (TBP) is relatively insufficient. The majority of reports are from a single center and do not assess predictive factors for mortality. In this international study, we investigated the clinicopathological characteristics of a large series of patients with TBP and determined the key features associated with mortality. TBP patients detected between 2010 and 2022 in 38 medical centers in 13 countries were included in this retrospective cohort. Participating physicians filled out an online questionnaire to report study data. In this study, 208 patients with TBP were included. Mean age of TBP cases was 41.4 ± 17.5 years. One hundred six patients (50.9%) were females. Nineteen patients (9.1%) had HIV infection, 45 (21.6%) had diabetes mellitus, 30 (14.4%) had chronic renal failure, 12 (5.7%) had cirrhosis, 7 (3.3%) had malignancy, and 21 (10.1%) had a history of immunosuppressive medication use. A total of 34 (16.3%) patients died and death was attributable to TBP in all cases. A pioneer mortality predicting model was established and HIV positivity, cirrhosis, abdominal pain, weakness, nausea and vomiting, ascites, isolation of Mycobacterium tuberculosis in peritoneal biopsy samples, TB relapse, advanced age, high serum creatinine and ALT levels, and decreased duration of isoniazid use were significantly related with mortality (p < 0.05). This is the first international study on TBP and is the largest case series to date. We suggest that using the mortality predicting model will allow early identification of high-risk patients likely to die of TBP.

BACKGROUND: To have country-wide information about multidrug resistance (MDR) in isolates from community-acquired urinary tract infections (CAUTI) of Turkey, in terms of resistance rates and useful options. METHODS: We used a geocode standard, nomenclature of territorial units for statistics (NUTS), and a total of 1588 community-acquired isolates of 20 centres from 12 different NUTS regions between March 2019 and March 2020 were analysed. RESULTS: Of the 1588 culture growths, 1269 (79. 9%) were Escherichia coli and 152 (9.6%) were Klebsiella spp. Male sex, advancedage, and having two or more risk factors showed a statistically significant relation with MDR existence (p < 0.001, p: 0.014, p < 0.001, respectively) that increasing number of risk factors or degree of advancing in age directly affects the number of antibiotic groups detected to have resistance by pathogens. In total, MDR isolates corresponded to 36.1% of our CAUTI samples; MDR existence was 35.7% in E. coli isolates and 57.2% in Klebsiella spp. isolates. Our results did not show an association between resistance or MDR occurrence rates and NUTS regions. DISCUSSION: The necessity of urine culture in outpatient clinics should be taken into consideration, at least after evaluating risk factorsfor antibacterial resistance individually. Community-acquired UTIs should be followed up time- and region-dependently. Antibiotic stewardship programmes should be more widely and effectively administrated.

OBJECTIVES: The aim of study was to determine the presence of some of the herpesviruses including herpes simplex virus (HSV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV) in adenoid tissues of children with adenoid hypertrophy (AH) and chronic adenoiditis (CA) and to investigate the potential role of the herpesviruses in patogenesis of AH and CA. PATIENTS AND METHODS: A total of 72 patients (41 boys, 31 girls; mean age 4 years and 2 months; range 2 to 9 years) who underwent adenoidectomy or adenotonsillectomy (with or without placement of a ventilation tube) in our clinic between October 2007 and May 2008, were included. The patients were divided into two groups, as AH group (n=42) and the CA group (n=30). Adenoid tissues collected from patients in both groups were analyzed by polymerase chain reaction (PCR) for the presence of HSV, EBV and CMV-DNA. RESULTS: The results of the PCR indicated that 33.3% in the AH group and 36.6% in the CA group were herpesvirus DNA positive. Among the herpesviruses studied, HSV-DNA was detected at the highest level (14.2% and 16.6%, respectively) in both groups, although the difference between the groups was not significant. EBV-DNA positiveness was 11.9% and CMV-DNA was 4.7% in the AH group, whereas, EBV-DNA positiveness was 13.3% and CMV-DNA was 6.6% in the CA group. CONCLUSION: Herpesviruses were determined at a high rate in adenoid tissue of children with AH and CA, suggesting that there may be a potential relationship between the presence of herpesviruses and occurrence of AH and CA in children. However, more extensive studies are required to elucidate the role of herpesviruses in the pathogenesis of AH or CA.

In this study, a machine learning-based decision support system that uses routine laboratory parameters has been proposed in order to increase the diagnostic success in COVID-19. The main goal of the proposed method was to reduce the number of misdiagnoses in the RT-PCR and CT scans and to reduce the cost of testing. In this study, we retrospectively reviewed the files of patients who presented to the coronavirus outpatient. The demographic, thoracic CT, and laboratory data of the individuals without any symptoms of the disease, who had negative RT-PCR test and who had positive RT-PCR test were analyzed. CT images were classified using hybrid CNN methods to show the superiority of the decision support system using laboratory parameters. Detection of COVID-19 from CT images achieved an accuracy of 97.56% with the AlexNet-SVM hybrid method, while COVID-19 was classified with an accuracy of 97.86% with the proposed method using laboratory parameters.
RESUMO
Background: Broad-spectrum empirical antimicrobials are frequently prescribed for patients with coronavirus disease 2019 (COVID-19) despite the lack of evidence for bacterial coinfection. Aims: We aimed to cross-sectionally determine the frequency of antibiotics use, type of antibiotics prescribed, and the factors influencing antibiotics use in hospitalized patients with COVID-19 confirmed by polymerase chain reaction. Study Design: The study was a national, multicenter, retrospective, and single-day point prevalence study. Methods: This was a national, multicenter, retrospective, and single-day point-prevalence study, conducted in the 24-h period between 00:00 and 24:00 on November 18, 2020, during the start of the second COVID-19 peak in Turkey. Results: A total of 1500 patients hospitalized with a diagnosis of COVID-19 were included in the study. The mean age ± standard deviation of the patients was 65.0 ± 15.5, and 56.2% (n = 843) of these patients were men. Of these hospitalized patients, 11.9% (n = 178) were undergoing invasive mechanical ventilation or ECMO. It was observed that 1118 (74.5%) patients were receiving antibiotics, of which 416 (37.2%) were prescribed a combination of antibiotics. In total, 71.2% of the patients had neither a clinical diagnosis nor microbiological evidence for prescribing antibiotics. In the multivariate logistic regression analysis, hospitalization in a state hospital (p < 0.001), requiring any supplemental oxygen (p = 0.005), presence of moderate/diffuse lung involvement (p < 0.001), C-reactive protein > 10 ULT coefficient (p < 0.001), lymphocyte count < 800 (p = 0.007), and clinical diagnosis and/or confirmation by culture (p < 0.001) were found to be independent factors associated with increased antibiotic use. Conclusion: The necessity of empirical antibiotics use in patients with COVID-19 should be reconsidered according to their clinical, imaging, and laboratory findings.

OBJECTIVES: Retropharyngeal abscess is a serious and life-threatening disease due to its anatomic location and potential to obstruct the upper airway. We evaluated the clinical characteristics, diagnosis, and treatment of patients with retropharyngeal abscesses. PATIENTS AND METHODS: The study included 10 patients (6 males, 4 females; mean age 9+/-11 years; range 4 months to 32 years) who received medical and surgical treatment with the diagnosis of retropharyngeal abscess. The patients were evaluated with respect to etiology, clinical symptoms and signs, treatment, complications, and hospital stay. RESULTS: The most frequent etiological factor was upper airway infection (70%), followed by dental abscess in two patients (20%), and soft tissue injury due to foreign body ingestion in one patient (10%). The presenting symptoms and signs included dysphagia (100%), respiratory distress (80%), limited neck motion (80%), fever (60%), and neck pain (50%). Treatment consisted of surgical drainage and parenteral antibiotic combination of cefazolin sodium and metronidazole. The mean hospital stay was 7.1+/-5.3 days. Complications were seen in two patients, being empyema and upper airway obstruction, respectively. CONCLUSION: Surgical drainage combined with early antibiotic treatment is an effective method in the management of retropharyngeal abscesses and in preventing complications.
