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.

Changing Bacterial Etiology and Antimicrobial Resistance Profiles as Prognostic Determinants of Diabetic Foot Infections: A Ten-Year Retrospective Cohort Study.

Background: In this single-center study, we analyzed a retrospective cohort of patients with diabetic foot infections (DFIs) between 2011 and 2020. Patients and Methods: The first and second five-year periods were compared. A poor prognosis was defined as a primary composite end point including re-infection, major amputation, or mortality at six months. Results: A total of 484 patients were enrolled. Overall, 269 patients had the primary composite end point. A substantial decrease was detected in the second five-year period in terms of re-infection (n = 132, 66.0% vs. n = 68, 23.9%; p < 0.001) and mortality (n = 22, 11.0% vs. n = 7, 2.5%; p < 0.001). A total of 798 micro-organisms were isolated from 484 patients. A substantial increase was detected in polymicrobial infections (48.5% vs. 65.1%; p = 0.001) as well as Streptococcus spp. (2.5% vs. 9.2%; p = 0.003), Corynebacterium spp. (9.5% vs. 22.9%; p < 0.001), and extended-spectrum ß-lactamase (ESBL) producing Escherichia coli (3.0% vs. 12.7%; p < 0.001) in the second five-year period, whereas the prevalence of multi-drug-resistanct (MDR) Pseudomonas aeruginosa (17.0% vs. 10.2%; p = 0.029) and carbapenem-resistant Acinetobacter baumannii (7.5% vs. 2.8%; p = 0.017) decreased. Multivariable regression analysis revealed that MDR Pseudomonas aeruginosa (odds ratio [OR], 1.917; 95% confidence interval [CI], 1.074-3.420; p = 0.028) and carbapenem-resistant Acinetobacter baumannii (OR, 3.069; 95% CI, 1.114-8.453; p = 0.030) were independent predictors for poor prognosis. Conclusions: This 10-year cohort study provides reassuring information about the changing epidemiology of DFIs and the prognostic determinants in patients with DFIs.

Knowledge and attitudes towards COVID-19 among emergency medical service workers.

OBJECTIVE: Good knowledge of the coronavirus disease 2019 (COVID-19) among healthcare workers is essential for keeping health systems active and controlling the outbreak. We aimed to investigate the knowledge and attitudes of Emergency Medical Service (EMS) employees who fight COVID-19 at the forefront. METHODS: A total of 400 EMS workers (doctors, nurses, emergency medical technicians, paramedics, and ambulance drivers) were included in this study. Knowledge, attitude, and preventive behaviors for COVID-19 were evaluated using an online questionnaire. RESULTS: A total of 275 EMS workers participated in the study with a response rate of 68.8%. The respondents reported that their highest common sources of knowledge about COVID-19 were social media and television (n=240, 88%). Overall, > 96% of the participants had adequate knowledge about the transmission routes of COVID-19. Among the respondents, 36% of them were unaware of the correct hand washing or scrubbing technique. In addition, 78% of the participants had poor knowledge about floor and surface disinfection. The majority of the participants exhibited inaccurate attitudes toward the use of personal preventive equipment. More than half of EMS workers (52%) agreed that a surgical mask is not enough during the procedures that do not generate aerosol. Moreover, a significant proportion of the participants (66%) perceived that a N95 mask is required. CONCLUSIONS: As a consequence, although emergency workers have sufficient basic knowledge about COVID-19, there is a need for postgraduate training in many subjects.

RESUMO OBJETIVO: Um bom conhecimento sobre a doença por coronavírus 2019 (COVID-19) entre profissionais de saúde é essencial para manter os sistemas de saúde ativos e controlar o surto. Nosso objetivo foi investigar o conhecimento e as atitudes dos funcionários do serviço médico de emergência (EMS) que lutam com o COVID-19 na vanguarda. MÉTODOS: Um total de 400 trabalhadores do SME (médicos, enfermeiros, técnico de emergência médica, paramédicos e motoristas de ambulância) foram incluídos neste estudo. Conhecimento, atitude e comportamentos preventivos para COVID-19 foram avaliados usando um questionário on-line. RESULTADOS: Um total de 275 trabalhadores do SME participou do estudo com uma taxa de resposta de 68,8%. Os entrevistados relataram que as maiores fontes comuns de conhecimento sobre COVID-19 foram as mídias sociais e a televisão (n = 240, 88%). No geral,> 96% dos participantes tinham conhecimento adequado sobre as rotas de transmissão do COVID-19. Entre os entrevistados, 36% deles desconheciam a técnica correta de lavar ou esfregar as mãos. Além disso, 78% dos participantes tinham pouco conhecimento sobre desinfecção de pisos e superfícies. A maioria dos participantes exibiu atitudes imprecisas em relação ao uso de equipamentos preventivos pessoais. Mais da metade dos trabalhadores do SME (52%) concordou que a máscara cirúrgica não é suficiente durante os procedimentos que não geram aerossol. Além disso, uma proporção significativa dos participantes (66%) percebeu que a máscara N95 é necessária. CONCLUSÕES: Como conseqüência, embora os trabalhadores de emergência tenham conhecimento básico suficiente sobre o COVID-19, há necessidade de treinamento de pós-graduação em muitas disciplinas.

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.

Association between biofilm and multi/extensive drug resistance in diabetic foot infection.

PURPOSE: We aimed to determine significant risk factors for biofilm production and to investigate the association between antimicrobial resistance profile and biofilm formation in the bacterial isolates obtained from patients with diabetic foot infection (DFI). METHODS: Demographic, clinical, laboratory and outcome data of 165 patients, prospectively recorded and followed between January 2008 and December 2015 by a multidisciplinary committee, were analysed. Standard microbiological methods were adopted. Risk factors associated with biofilm were determined by univariate and multivariate analyses. RESULTS: The overall rate of biofilm production among 339 wound isolates was 34%. The biofilm production rate was significantly higher in Gram-negative micro-organisms (39%) in comparison with Gram positives (21%) (P = .01). A. baumannii presented the highest biofilm production (62%), followed by P. aeruginosa (52%) and Klebsiella spp. (40%). On univariate analysis, significant factors associated with biofilm were antibiotic use within last 3 months (OR:2.94, CI: 1.5-5.75, P = .002), recurrent DFI within last 6 months (OR:2.35, CI: 1.23-4.53, P = .01), hospitalisation within last 3 months due to ipsilateral recurrent DFI (OR:2.44, CI: 1.06-5.58, P = .03), presence of amputation history (OR: 2.20, CI: 1.14-4.24, P = .01), multidrug-resistant (MDR) micro-organism (OR: 7.76, CI: 4.53-13.35, P<.001) and extensively drug-resistant (XDR) micro-organism (OR:11.33, CI:4.97-26.55, P<.001). Multivariate regression analysis revealed two variables to be significant factors associated with biofilm: MDR micro-organism (OR: 3.63, CI: 1.58-8.33, P = .002) and XDR micro-organism (OR:4.06, CI: 1.25-13.1, P = .01). CONCLUSIONS: Multi/extensive drug resistance and previous recurrent DFIs were significantly associated with biofilm formation in patients with diabetic foot.

[A case of Fasciola hepatica mimicking sepsis without eosinophilia]. / Sepsis gibi Prezente Olan Eozinofilisiz Fasciola hepatica Vakasi.

Fasciolosis is a rare cause of hepatobiliary system infections and caused by the trematode Fasciola hepatica. It primarily infects sheeps or goats, and humans are accidental hosts. On laboratory findings, marked eosinophilia is present in most of the cases. Here, we report a case of fasciolosis without eosinophilia who was presented as sepsis and responded to therapy in second dose of triclabendazole. Sepsis like clinical presentation has been reported in few cases. Forty-eight year old female patient presented with high fever, abdominal pain, hypotension and tachycardia. The patient was considered as sepsis secondary to liver abscess, which was demonstrated on the initial abdominal ultrasonography (USG) findings. Therefore, empirical antibiotic therapy was started. Due to failure of the treatment, the image was found to be compatible with fasciolosis on control magnetic resonance imaging (MRI) and USG. On detailed anamnesis, history of eating watercress was learned and the diagnosis of fasciolosis was confirmed by serological tests.
