    Objective: We aim to show whether endoscopic, histopathological and precancerous findings in childhood Helicobacter pylori (H. pylori) infection are associated with some changes in the host immune system and some virulence factors of the bacteria. For this purpose, we interpreted the changes in endoscopic and histopathological findings of TLR-4 and TLR-9 gene polymorphisms in the innate immune system of the host and cytotoxin associated gene A (Cag-A) and vacuolating cytotoxin A (Vac-A) positivity, the main virulence factors of the bacteria. Method: Between April 2009 and October 2010, 100 H. pylori-positive and 100 H. pylori-negative cases were cross-sectionally selected by retrospectively reviewing the files of patients admitted to a tertiary hospital with dyspepsia. After obtaining informed consent, blood samples from these patients were analysed for TLR-4 [Asp 299 Gly (rs4986790)] and TLR-9 [1237TC (rs574 3836)] gene polymorphisms and for the presence of Cag-A and Vac-A in isolates obtained from pathological specimens. Results: Poor socio-economic conditions were an important risk factor for H. pylori. The presence of Cag-A increased the likelihood of duodenal ulcer. There was no significant difference between TLR-4 [Asp 299 Gly (rs4986 790)] gene polymorphism and endoscopic and histopathological findings. However, TLR-9 [-1237TC (rs5743836)] polymorphism increased precancerous intestinal metaplasia and atrophy. Conclusion: The presence of Cag-A increases the risk of duodenal ulceration due to H. pylori infection. The TLR-9 [-1237TC (rs5743836)] polymorphism is associated with gastric atrophy and intestinal metaplasia in the pathogenesis of H. pylori infection. Studies in large groups of patients are needed.

    Maturity onset diabetes is a genetic form of diabetes mellitus characterized by an early age at onset and several etiologic genes for this form of diabetes have been identified in many patients. Maturity onset diabetes type 2 [MODY2 (#125851)] caused by mutations in the glucokinase gene (GCK). Although its prevalence is not clear, it is estimated that 1%-2% of patients with diabetes have the monogenic form. The aim of this study was to evaluate the molecular spectrum of GCK gene mutations in 177 Turkish MODY type 2 patients. Mutations in the GCK gene were identified in 79 out of 177. All mutant alleles were identified, including 45 different GCK mutations, 20 of which were novel.

    Objective: In the early stages of any epidemic caused by new emerging pathogens healthcare personnel is subject to a great risk. Pandemic caused by SARS-CoV-2, proved to be no exception. Many healthcare workers died in the early stages of pandemic due to inadequate precautions and insufficient protection. It is essential to protect and maintain the safety of healthcare personnel for the confinement of pandemic as well as continuity of qualified healthcare services which is already under strain. Educating healthcare personnel on appropiate use of personal protective equipment (PPE) is as essential as procuring them. Material and Methods: A survey is conducted on 4927 healthcare personnel working solely with pediatric patients from 32 different centers. Education given on PPE usage were questioned and analyzed depending on age, sex, occupation and region. Results: Among four thousand nine hundred twelve healthcare personnel from 32 different centers 91% (n=4457) received education on PPE usage. Of those who received education only 36% was given both theoretical and applied education. Although there was no differences among different occupation groups, receiving education depended on regions. Conclusion: It is essential to educate healthcare personnel appropiately nationwidely for the continuity of qualified healthcare services during the pandemic.

    Background: Understanding SARS-CoV-2 seroprevalence among health care personnel is important to ex-plore risk factors for transmission, develop elimination strategies and form a view on the necessity and frequency of surveillance in the future. Methods: We enrolled 4927 health care personnel working in pediatric units at 32 hospitals from 7 different regions of Turkey in a study to determine SARS Co-V-2 seroprevalence after the first peak of the COVID-19 pandemic. A point of care serologic lateral flow rapid test kit for immunoglobulin (Ig)M/IgG was used. Seroprevalence and its association with demographic characteristics and possible risk factors were analyzed. Results: SARS-CoV-2 seropositivity prevalence in health care personnel tested was 6.1%. Seropositivity was more common among those who did not universally wear protective masks (10.6% vs 6.1%). Having a COVID-19-positive co-worker increased the likelihood of infection. The least and the most experienced personnel were more likely to be infected. Most of the seropositive health care personnel (68.0%) did not suspect that they had previously had COVID-19. Conclusions: Health surveillance for health care personnel involving routine point-of-care nucleic acid testing and monitoring personal protective equipment adherence are suggested as important strategies to protect health care personnel from COVID-19 and reduce nosocomial SARS-CoV-2 transmission.
