Extrapulmonary tuberculosis (EPTB) is an important public health problem due to its diverse clinical presentations, diagnostic complexities, and significant impact on patient outcomes and public health. Our study aimed to understand the sociodemographic, clinical, and laboratory characteristics as well as diagnostic and treatment modalities of adult patients with EPTB. This is a multicentric retrospective study that covers patients with EPTB cases followed up from January 2015 to December 2022 among tuberculosis (TB) dispensaries and Infectious Diseases and Clinical Microbiology clinics of 15 hospitals located in various regions of Turkey. The study included 64.6% women with a mean age of 44 years and a mortality rate of 3.5% within 1 year of diagnosis. Initial constitutional symptoms were predominantly fatigue (57%) and anorexia (53.7%). The most commonly affected sites were the lymph nodes (49.1%) and pleura (9.7%). The lumbar region was particularly involved in cases with spinal TB. Diagnostic findings included acid-fast bacilli positivity in 27.5% of cases, tuberculosis polymerase chain reaction positivity in 41%, elevated adenosine deaminase levels in 91.2% (especially in pleural and peritoneal fluids), and mycobacterial culture positivity in 40.9%. Pathology slides showed granulomatous inflammation in 97.7%. Increased C-reactive protein (CRP) levels correlated with the number of organs affected. Anti-TB treatment-related hepatotoxicity was detected in 8.9% of patients. In this study, it is important to note that the lumbar region is predominantly affected with involvement in spinal region. CRP level was consistent with the number of organ involvements and was one of the most critical results of this study., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Tuberculous lymphadenitis (TBLN) is the most common infectious etiology of peripheral lymphadenopathy in adults, in Turkiye. This study aimed to identify the demographic, clinical, and laboratory variables that differentiate TBLN from non-tuberculous lymphadenitis (NTBLN), as well as the etiology of lymphadenopathy in adults., Methodology: Patients who were over 18 years old and were referred to the infectious disease outpatient clinics with complaints of swollen peripheral lymph nodes, and who underwent lymph node biopsy between 1 January 2010 and 1 March 2021, were included in this multicenter, nested case-control study., Results: A total of 812 patients at 17 tertiary teaching and research hospitals in Turkiye were included in the study. TBLN was the most frequent diagnosis (53.69%). The proportion of patients diagnosed with TBLN was higher among females; and among those who had a higher erythrocyte sedimentation rate, positive purified protein derivative test, and positive interferon-gamma release test result (p < 0.05). However, TBLN was less frequent among patients with generalized lymphadenopathy, bilateral lymphadenopathy, axillary lymphadenopathy, inguinal lymphadenopathy, hepatomegaly, splenomegaly, leukocytosis, and moderately increased C reactive protein levels (p < 0.05)., Conclusions: Identifying the variables that predict TBLN or discriminate TBLN from NTBLN will help clinicians establish optimal clinical strategies for the diagnosis of adult lymphadenopathy., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Ercan Yenilmez, Duygu Özakınsel, Adem Köse, Yıldız Olçar, Zehra Duman, Mehmet R Ceylan, Fatma Bozkurt, Lütfiye N Altunal, Yakup Gezer, Ali Asan, Sibel Y Göktaş, Sümeyye Köşger, Kamil Mert, Derya Seyman, Salih Emre, Leman Karaağaç, Emine Parlak, Gülten Ünlü, İlknur E Yıldız, Nevin İnce, Şafak Kaya, Aysun Yalçı, Aziz A Hamidi, Semiha Ç Ekinci, Ersin Tural, Ali Mert, Şükran Köse.)

The tetanus vaccine is not routinely given to Turkish adults. Protective tetanus immunity decreases with age. Health-care personnel (HCPs), who are role models in the field of health, are a target group in order to achieve a higher rate of tetanus vaccination in the community. This study was designed to evaluate attitudes and coverage regarding tetanus vaccination among a large sample of Turkish HCPs. This cross-sectional epidemiologic study was conducted from July to August 2019. A questionnaire was sent to HCPs using social media. Of the 10,644 HCPs included in the study, 65% were female. Overall, the tetanus vaccination coverage (TVC) among HCPs was 78.5% (95% CI: 77.7%-79.3%). TVC was significantly higher among physicians [83.4% (95% CI: 82%-84.6%); p < .001] compared with all other HCPs except nurses. Older age (≥40 years) and length of professional experience were significantly correlated with TVC. Of the 8353 HCPs who received tetanus vaccines during their lifetime, 73.03% received tetanus vaccination in the past 10 years. The self-vaccination rate for protection against tetanus was 13.1%. Acute injuries (25.42%) and pregnancy (23.9%) were the most common reasons for having the tetanus vaccine. One-third (33.7%) of HCPs did not have information about whether pregnant women could receive tetanus vaccinations. This survey study provided excellent baseline information about HCPs' coverage rates and attitudes regarding tetanus vaccination. The present results suggested that tetanus boosters for HCPs should be established as soon as possible, and revealed that the HCPs younger than 30 years with relatively less professional experience and all other HCPs except nurses and physicians should be identified as the target population for future intervention programs.

Peripheral lymphadenopathy (LAP) is an important and common abnormal finding of the physical exam in general medical practice. We aimed to reveal the LAP etiology and demographic, clinical and laboratory variables that may be useful in the differential evaluation of LAP. This multicenter, nested case-control study including 1401 patients between 2014 and 2019 was conducted in 19 tertiary teaching and research hospitals from different regions in Turkey. The ratio of infectious, malign and autoimmune/inflammatory diseases was 31.3%, 5% and 0.3%, respectively. In 870 (62%) of patients had nonspecific etiology. Extrapulmonary tuberculosis (n: 235, 16.8%) was the most frequent cause of LAP. The ratio of infective etiology of LAP was significantly lower in patients older than 65 years-old compared to younger patients with the rate of 66.67% and 83.84%, respectively (p 0.016, OR 0.386, 95% Cl 0.186-0.803). The probability of malign etiology was higher both in patients who are older than 45 years-old (p < 0.001, OR 3.23, 95% Cl 1.99-5.26) and older than 65 years-old (p 0.002, OR 3.36, 95% Cl 1.69-6.68). Age, localization and duration of LAP, leukocytosis, anemia, thrombocytopenia, CRP and sedimentation rate were important parameters to differentiate infections. Size of lymph node and splenomegaly in addition to the parameters above were useful parameters for differentiating malign from benign etiology. Despite the improvements in diagnostic tools, reaching a definite differential diagnosis of lymphadenopathy is still challenging. Our results may help clinicians to decide in which cases they need an aggressive workup and set strategies on optimizing the diagnostic approach of adulthood lymphadenopathy., (© 2021.

Background: This study aimed to investigate the prevalence of the disease and testing and vaccination status of healthcare workers in terms of hepatitis A infection as well as their awareness. This study is a multicenter descriptive study performed with healthcare workers., Material and Methods: Testing status for hepatitis A, awareness of the results and vaccination status of healthcare workers were compared., Results: Of the 12,476 healthcare workers participating in the study, only 65% (8,115 healthcare workers) had awareness of hepatitis A test results. Of the participants, 6,481 (66.3 %) stated that they were not vaccinated against hepatitis A. Vaccination rates against hepatitis A decreased with increasing age (P < .01). The rates of vaccination in all departments where participants worked were above 60% (P < .05). While the rate of protection among those working in departments creating a risk for hepatitis A virus infection was higher, no difference among vaccination rates was observed compared with the other departments., Conclusion: Vaccination of seronegative individuals is the safest way for hepatitis A, which can progress to fulminant hepatitis at advanced ages. It must be aimed primarily to increase the awareness of healthcare professionals and to increase the vaccination rates for hepatitis B and hepatitis A for the prevention of viral hepatitis. In our study, the awareness level was found to be above 50%, and the vaccination level was 35%, which is a rate that must be increased., (© 2021 John Wiley & Sons Ltd.)

Aims: The differential diagnosis of Fever of Unknown Origin (FUO) is still a major clinical challenge despite the advances in diagnostic procedures. In this multicentre study, we aimed to reveal FUO aetiology and factors influencing the final diagnosis of FUO in Turkey., Methods: A total of 214 patients with FUO between the years 2015 and 2019 from 13 tertiary training and research hospitals were retrospectively evaluated., Results: The etiologic distribution of FUO was infections (44.9%), malignancies (15.42%), autoimmune/inflammatory (11.68%) diseases, miscellaneous diseases (8.41%) and undiagnosed cases (19.62%). Brucellosis (10.25%), extrapulmonary tuberculosis (6.54%) and infective endocarditis (6.54%) were the most frequent three infective causes. Solid malignancies (7.1%) and lymphoma (5.6%), adult-onset still's disease (6.07%) and thyroiditis (5.14%) were other frequent diseases. The aetiological spectrum did not differ in elderly people (P < .05). Infections were less frequent in Western (34.62%) compared with Eastern regions of Turkey (60.71%) (P < .001, OR: 0.31, 95% Cl: 0.19 to 0.60). The ratio of undiagnosed aetiology was significantly higher in elderly people (p: 0.046, OR: 2.34, 95% Cl: 1.00 to 5.48) and significantly lower in Western Turkey (P: .004, OR: 3.07, 95% Cl: 1.39 to 6.71)., Conclusions: Brucellosis, extrapulmonary tuberculosis and infective endocarditis remain to be the most frequent infective causes of FUO in Turkey. Solid tumours and lymphomas, AOSD and thyroiditis are the other common diseases. The aetiological spectrum did not differ in elderly people, on the other hand, infections were more common in Eastern Turkey. A considerable amount of aetiology remained undiagnosed despite the state-of-the-art technology in healthcare services., (© 2021 John Wiley & Sons Ltd.)

Objective: The aim of this study is to assess the epidemiology of foodborne botulism cases which were seen and published in Turkey., Material and Methods: This study covers the cases and outbreaks of botulism that have been identified and published in any region of Turkey, between 1983 and 2017. This systematic review was performed in accordance with the guidelines for performing and reporting systematic reviews and meta-analyses. The search was done on PubMed and Google in English and Turkish languages. Demographic features of the cases, nutritional sources, the development process of the disease, clinical symptoms and signs, the duration of hospitalization, treatment and mortality rates were analyzed., Results: Totally 95 patients (57 female and 38 male) were assessed from the published. The food which caused the majority of intoxication cases was canned green beans, and all the foods were home-canned goods. There cords showed that botulism antitoxin was given to 56 patients. The time from exposure to illness onset was 26.9 h. While 18 patients died at the end of follow-up and treatment (mortality 19%), 77 patients were discharged with full recovery., Conclusion: Among 95 botulism cases, spread in Turkey over the last 35 years, the predominant source of toxin was home-canned food and green beans, in particular. Since community and emergency room physicians may be the first to treat patients with any type of botulinum intoxication, they must know how to diagnose and treat this rare but potentially lethal disease.

In this study, drug resistance of 28 ESBL-producing Escherichia coli isolates obtained from 144 patients hospitalized at the Yüzüncüyil University Hospital at Van (YUH), Turkey, between 2009 and 2012 were characterized by pulsed field gel electrophoresis and antibiotic susceptibility tests. Antibiotic resistance profile was determined by Phoenix automated system (BD, USA). The ratio of ESBL-producing E. coli strains was determined to be 19.4% (28 out of 144 E. coli isolates). It was determined that the anaesthesiology, paediatrics and thoracic medicine intensive care units in YUH were cross-contaminated between 2009 and 2012 by ESBL-producing E. coli strains, which is a sign of nosocomial infection in YUH. Analysis of PFGE results gave rise to two main PFGE profiles, profile-A with four subprofiles and profile-B with three subprofiles, where profile-A predominates over profile-B (14%). Comparison of the antibiotic resistance profile with the PFGE profile yielded similarities while some differences also exist due to either identical restriction enzyme cutting sites with slightly different genetic sequences in between the cutting sites or newly formed restriction enzyme cutting sites that do not affect antibiotic resistance genes. Enterobacteriaceae, particularly E. coli, have developed resistance in YUH by producing ESBLs against oxyimino and non-oxyimino cephalosporins, and penicillin-type antibiotics. Therefore, more effective antibiotics such as cefoxitin or cefoperazone-sulbactam should be used for the treatment of future nosocomial infections in YUH while hospital staff should take care with hygiene, such as hand washing.
