New Prognostic Parameter of West Nile Virus: Platelet Distribution Width.

Background: West Nile virus (WNV) infection is a viral disease caused by arboviruses. It can cause epidemics of febrile diseases and meningoencephalitis, especially at the end of the summer season. In this study, we aimed to determine the risk factors of WNV encephalitis with a case-control study of the patients followed in our clinic. Materials and Methods: Among the patients who applied to our hospital with sudden onset fever, headache, myalgia, nausea, vomiting, maculopapular rash, viral meningitis, or encephalitis findings in late summer and early autumn, those diagnosed with positive WNV PCR and antibody tests were defined as WNV cases. In the same date range, patients with clinically compatible but negative serological and PCR tests for WNV in our hospital were considered as the control group. Results: WNV infection was diagnosed in 26 of 48 patients who were examined with a preliminary diagnosis of WNV infection, and the other 22 patients were considered as the control group. A statistically significant difference was found between the two groups in C-reactive protein, procalcitonin, 1-h erythrocyte sedimentation rate, alkaline phosphatase, platelet, and platelet distribution width (PDW). PDW >17.85% indicated WNV infection with 82% sensitivity and 91% specificity. PDW percentage >17.85 increased the risk of WNV infection by 6.1 times. The power of the study was calculated as 83%. Conclusion: The most common findings in WNV cases were fever and confusion. WNV infection should be considered in the differential diagnosis in patients with fever and confusion in September and October in settlements on the migration route of birds. The percentage of PDW in whole blood examination can guide the differential diagnosis of WNV cases.

Main symptoms in patients presenting in the COVID-19 period.

BACKGROUND: The first case of a novel coronavirus (COVID-19) infection was detected in Wuhan, fever and respiratory symptoms have been frequently reported in patients infected with this virus. AIM: It was aimed to compare the symptoms of patients with COVID-19 positivity and patients without COVID-19 positivity hospitalized with suspicion of COVID-19. METHODS: Patients presenting to the Sakarya University Training and Research Hospital with suspicion of COVID-19 were included in the study. Samples were obtained from the patients and PCR tests were performed; the patients were grouped as COVID-19 positive and COVID-19 negative; these two groups were questioned for 15 symptoms and the results were compared. RESULTS: A total of 297 patients with suspicion of COVID-19 were included in the study. COVID-19 was positive in 143 patients and negative in 154 patients. The most common symptoms in the COVID-19 positive group were: cough (56.6%), weakness (56.6%), taste disorder (35.7%), myalgia (34.3%), and fever (33.6%); and in the COVID-19 negative group: cough (63%), weakness (45.5%), dyspnea (29.9%), headache (27.3%) and fever (24.7%). When these two groups were compared, taste disorder, smell disorder and diarrhea were significantly higher in the COVID-19 positive group (p = <0,00001, p = 0,00001 and p = 0,02). CONCLUSION: Our study showed that taste and smell disorders and diarrhea were important markers in COVID-19 infection.

Evaluation of Antibiotic Prophylaxis and Discharge Prescriptions in the General Surgery Department.

Introduction Although there are international guidelines for surgical antibiotic prophylaxis (SP), the use of inappropriate SP is still a common problem. Most studies investigated SP applications in clean and clean-contaminated cases. However, antibiotics in the discharge prescriptions of these cases have not been adequately investigated. In this study, we aimed to examine the antibiotics in SP applications and discharged prescriptions together and to find out the causes of inappropriate use. Materials and methods We retrospectively evaluated the data of patients admitted to our general surgery wards between 2014 and 2015. Patients with clean or clean-contaminated wound category operations were included. The patients were evaluated in terms of convenience of SP (choice of antibiotics, compliance with an indication for SP, timing of the first dose, SP>24 hours, and discharge prescription). In addition, to interpret the results, a questionnaire has been performed for the surgeons in the same clinics. Results A total of 1205 patients with clean and clean-contaminated wound class operation were enrolled in this study. The total accuracy rate of SP was 7.1%. SP application with the correct indication and timing of the first dose was compatible with guidelines: 55.6% and 81.9%, respectively. SP was applied >24 hours at 60.2% and antibiotic prescribing carried out after discharge at 80.6% of patients. According to questionnaire results, the use of SP over 24 hours and the prescription of antibiotics during discharge were: drain usage, hyperthermia, leukocytosis, surgeons feeling of comfort, avoidance of patients, and their relatives' reactions. Conclusion The total accuracy rate of SP rate was low in the present study and in surgeons prescribing the SP after discharge. In light of the present study, we suggest that discharge prescriptions should also be reviewed in clinics who have a high inappropriate surgical antibiotic prophylaxis rate.

Different presentation types of primary Brucella epididimo-orchitis.

Brucellosis is a zoonotic disease that involved genitourinary system in 2-20% and most commonly cause single sided epididymo-orchitis. In our country Brucella is an endemic disease and causes serious and different diagnosis of acute scrotum and epididymo-orchitis. In this paper six cases of epididymo-orchitis cases which were resistant to classical treatment were discussed according to clinical and laboratory findings. We describe different types of presentation of Brucella epididymo-orchitis with diagnosis and treatment modalities.
