Highlights High PSS on chest CT is associated with poor outcomes in COVID-19 patients. Low PMA and PMI on chest CT is associated with poor outcomes in COVID-19. Late admission to the hospital is associated with poor outcomes in COVID-19. Diabetes and high fever at admission are associated with poor outcomes in COVID-19. Being > 65 years old is an independent risk factor for intubation in COVID-19.

The fatality rate of Crimean-Congo haemorrhagic fever (CCHF) disease has been reported as 5.4-80%. In this prospective study our aim was to evaluate the clinical and laboratory predictors of fatality in patients with CCHF. Among probable CCHF patients admitted to our clinic between 2005 and 2008, patients with positive IgM antibodies and/or polymerase chain reaction for CCHF virus were included in the study. To determine the predictors of fatality, we compared epidemiological, clinical and laboratory findings of the fatal cases with survivors. Ninety-three confirmed CCHF patients were included in the study; 56 (60.2%) of them were female. Mean patient age was 48.4+/-17.7 y and mean hospital stay was 7.9+/-3.0 days. Five patients died (5.4%). The rates of haemorrhage, diarrhoea and confusion were higher in fatal cases compared with non-fatal cases (p<0.05). Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, lactate dehydrogenase (LDH), and C-reactive protein levels were higher in fatal cases; the international normalized ratio (INR) and activated partial thromboplastin time (aPTT) were longer and mean platelet counts were lower (p<0.05). By multivariate analysis, diarrhoea, melena, haematemesis, haematuria, elevated ALT and LDH, and prolongation of aPTT were independent clinical and laboratory predictors associated with fatality. We suggest that for patients who have diarrhoea, melena, haematemesis, haematuria, elevated AST and LDH, and a prolonged aPTT, physicians should be aware of the high fatality risk.

BackgroundTraining of infectious disease (ID) specialists is structured on classical clinical microbiology training in Turkey and ID specialists work as clinical microbiologists at the same time. Hence, this study aimed to determine the clinical skills and knowledge required by clinical microbiologists.MethodsA cross-sectional study was carried out between June 1, 2010 and September 15, 2010 in 32 ID departments in Turkey. Only patients hospitalized and followed up in the ID departments between January-June 2010 who required consultation with other disciplines were included.ResultsA total of 605 patients undergoing 1343 consultations were included, with pulmonology, neurology, cardiology, gastroenterology, nephrology, dermatology, haematology, and endocrinology being the most frequent consultation specialties. The consultation patterns were quite similar and were not affected by either the nature of infections or the critical clinical status of ID patients.ConclusionsThe results of our study show that certain internal medicine subdisciplines such as pulmonology, neurology and dermatology appear to be the principal clinical requisites in the training of ID specialists, rather than internal medicine as a whole.

SUMMARY – Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral zoonosis. The incidence of zoonotic diseases has been shown to be affected by climatic factors. In this study, we evaluated patients endemic to the CCHF region and examined the relationship between the number of patients and climatic properties of the region where they lived. The study included 548 CCHF patients. Along with the patient demographic and clinical characteristics, we recorded temperature, humidity and precipitation in the places where they lived at the time of their admission to the hospital. In addition to temperature, humidity and precipitation at the time of patient admission, these values were assessed at one month and three months prior to admission. The relationship between the number of patients and the above-mentioned values was examined. Humidity at the time of and one month prior to hospital admission, and precipitation three months prior to hospital admission were found to affect the number of patients admitted to the hospital for CCHF. In conclusion, climate appeared to affect the number of CCHF patients. We believe that the number of patients presenting to the hospital with CCHF could be predicted by taking into account climatic properties of the places where CCHF has been recorded, along with undertaking necessary measures.

Background/Aim: To investigate the relationship between imaging findings and peripheral blood cell counts of COVID-19 patients and the degree of thymus fat involution of these patients.Materials and methods: Computed tomography (CT) images of 87 patients with COVID-19 positive through RT-PCR testing were evaluated retrospectively by two radiologists. Ground glass densities and other signs of viral pneumonia were recorded, lung involvement was scored quantitatively. The patients thymus fat involution was graded on CT. Neutrophillymphocyte ratio (NLR), plateletlymphocyte ratios (PLR), lymphocyte and platelet counts were calculated. Imaging findings and degrees of thymus fat involution were compared with laboratory data.Results: Quantitative scoring of lung involvement was calculated at mean 6.63±4.70 (1-23) for observer 1 and mean 6.55±4.65(1-23) for observer 2 (K=0.824 -1,000). Statistical significance was determined between the increase in age and the increase in scores of lung findings(p=0.003). Lymphocyte count(p=0.0001) and PLR(p=0.001) were significantly lower in patients with severe CT involvement. A statistically significant correlation was found between increased thymus fat component and presence of COVID-19 lung involvement in CT (r = 0.461). Conclusion:The severity of imaging findings for COVID-19 patients significantly correlates with the degree of fat involution in patients' thymus tissue.
