RESUMEN
Chronic hepatitis B infection caused by Hepatitis B virus (HBV), influences over two billion people worldwide despite having an effective vaccine. With a total prevalence of 4.57%, there are 3.3 million estimated HBV carriers in Türkiye. Methylene-tetrahydrofolate reductase (MTHFR) arrange folate metabolism through nucleic acid synthesis and DNA methylation. C677T (rs1801133, p.Ala222Val) and A1298C (rs1801131, p.Glu429Ala) polymorphisms of MTHFR gene have effect of reducing the activity of enzyme. We purposed to investigate the correlation between C677T and A1298C polymorphisms of MTHFR gene with HBV infection in a Turkish population. One hundred eighteen HBV-infected participants and ninety healthy controls were incorporated in this research. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was applied to discover the genotypes of MTHFR polymorphisms. We demonstrated that T allele and CT + TT genotype frequencies of C677T polymorphism were significantly increased in HBV-infected participants than healthy controls [p = 0.015, OR (95% Cl) = 1.7 (1.11-2.79) and p = 0.020, OR (95% Cl) = 1.9 (1.10-3.42), respectively). No significant associations were noted concerning the A1298C polymorphism (p > 0.05). CC-AA composite genotype was observed to be significantly elevated in healthy controls than HBV-infected participants (32.2% vs. 13.6%, p = 0.001). In addition, the frequency of T-C haplotype was found to be considerably higher in the patient group than control group (15.8% vs 11.8%, p = 0.018). In conclusion, we found that T allele of C677T polymorphism poses a risk factor for HBV infection. We also discovered a protective impact of the CC-AA composite genotype against HBV infection and a risk effect of the T-A haplotype for HBV-infection.

BACKGROUND: People who inject drugs (PWID) should be treated in order to eliminate hepatitis C virus in the world. The aim of this study was to compare direct-acting antivirals treatment of hepatitis C virus for PWID and non-PWID in a real-life setting. METHODS: We performed a prospective, non-randomized, observational multicenter cohort study in 37 centers. All patients treated with direct-acting antivirals between April 1, 2017, and February 28, 2019, were included. In total, 2713 patients were included in the study among which 250 were PWID and 2463 were non-PWID. Besides patient characteristics, treatment response, follow-up, and side effects of treatment were also analyzed. RESULTS: Genotype 1a and 3 were more prevalent in PWID-infected patients (20.4% vs 9.9% and 46.8% vs 5.3%). The number of naïve patients was higher in PWID (90.7% vs 60.0%), while the number of patients with cirrhosis was higher in non-PWID (14.1% vs 3.7%). The loss of follow-up was higher in PWID (29.6% vs 13.6%). There was no difference in the sustained virologic response at 12 weeks after treatment (98.3% vs 98.4%), but the end of treatment response was lower in PWID (96.2% vs 99.0%). In addition, the rate of treatment completion was lower in PWID (74% vs 94.4%). CONCLUSION: Direct-acting antivirals were safe and effective in PWID. Primary measures should be taken to prevent the loss of follow-up and poor adherence in PWID patients in order to achieve World Health Organization's objective of eliminating viral hepatitis.

BACKGROUND: The number and proportion of elderly patients living with chronic hepatitis C are expected to increase in the coming years. We aimed to compare the real-world efficacy and safety of direct-acting antiviral treatment in elderly and younger Turkish adults infected with chronic hepatitis C. METHODS: In this multicenter prospective study, 2629 eligible chronic hepatitis C patients treated with direct-acting antivirals between April 2017 and December 2019 from 37 Turkish referral centers were divided into 2 age groups: elderly (≥65 years) and younger adults (<65 years) and their safety was compared between 2 groups in evaluable population. Then, by matching the 2 age groups for demographics and pretreatment risk factors for a non-sustained virological response, a total of 1516 patients (758 in each group) and 1244 patients (622 in each group) from the modified evaluable population and per-protocol population were included in the efficacy analysis and the efficacy was compared between age groups. RESULTS: The sustained virological response in the chronic hepatitis C patients was not affected by the age and the presence of cirrhosis both in the modified evaluable population and per-protocol population (P = .879, P = .508 for modified evaluable population and P = .058, P = .788 for per-protocol population, respectively). The results of the per-protocol analysis revealed that male gender, patients who had a prior history of hepatocellular carcinoma, patients infected with non-genotype 1 hepatitis C virus, and patients treated with sofosbuvir+ribavirin had a significantly lower sustained virological response 12 rates (P < .001, P = .047, P = .013, and P = .025, respectively). CONCLUSION: Direct-acting antivirals can be safely used to treat Turkish elderly chronic hepatitis C patients with similar favorable efficacy and safety as that in younger adults.

Crimean-Congo hemorrhagic fever (CCHF) is a deadly viral disease. Methylene-tetrahydrofolate reductase (MTHFR) has an important role in folate metabolism, and also in the formation of new cells, DNA synthesis, repair and methylation. We aimed to examine the relationship between MTHFR gene C677T (Ala222Val, rs1801133) and A1298C (Glu429Ala, rs1801131) polymorphisms with CCHF in a Turkish population. Totally 273 participants were included in the current study. One hundred forty-one participants were CCHF patients and one hundred thirty-two participants were healthy controls. The polymerase chain reaction (PCR) and further restriction fragment length polymorphism (RFLP) assays were applied to determine the genotypes of MTHFR polymorphisms. We did not find any differences between the CCHF patients and healthy controls in terms of allele and genotype distributions of both the C677T and A1298C polymorphisms. In composite genotype analysis between different groups, the frequency of CT-AA composite genotype, which is formed by C677T-A1298C polymorphisms, was found to be significantly higher in Mild CCHF patients compared to both Severe CCHF patients and controls (p = 0.036 and p = 0.008, respectively). In conclusion, in this study, we found a relationship between CCHF and MTHFR gene polymorphisms. CT-AA composite genotype of MTHFR gene C677T and A1298C polymorphisms showed a predisposition to Mild CCHF.

BACKGROUND: Mucormycosis is an emerging aggressive mold infection. This study aimed to assess the outcome of hospitalized adults with rhino-orbito-cerebral mucormycosis (ROCM). The secondary objective was to identify prognostic factors in this setting. METHODS: This study was an international, retrospective, multicenter study. Patients' data were collected from 29 referral centers in 6 countries. All qualified as "proven cases" according to the EORTC/MSGERC criteria. RESULTS: We included 74 consecutive adult patients hospitalized with ROCM. Rhino-orbito-cerebral type infection was the most common presentation (n = 43; 58.1%) followed by rhino-orbital type (n = 31; 41.9%). Twenty (27%) had acquired nosocomial bacterial infections. A total of 59 (79.7%) patients (16 in combination) received appropriate antifungal treatment with high-doses of liposomal amphotericin B. Fifty-six patients (75.7%) underwent curative surgery. Thirty-five (47.3%) required intensive care unit admission (27; 36.5% under mechanical ventilation). Hospital survival was 56.8%, being reduced to 7.4% in patients with invasive mechanical ventilation. A multivariate binary backward logistic regression model identified confusion at admission (OR 11.48), overlapping hospital-acquired infection (OR 10.27), use of antifungal treatment before diagnosis (OR 10.20), no surgical debridement (OR 5.92), and the absence of prior sinusitis (OR 6.32) were independently associated with increased risk for death. CONCLUSION: Today, ROCM still has high mortality rate. Improving source control, rational therpy, and preventing nosocomial infections may improve survival in this severe infection.

OBJECTIVES: Turkey is one of the countries that has the most cases of CCHF in recent years among the endemic countries. The disease also poses an important health threat with high mortality rate. The aim of the study was to determine the seroprevalence and risk factors of CCHF in adults aged ≥20 years in Tokat in the endemic region, Turkey. METHODS: In this population-based cross-sectional study, a total of 85 Family Medicine Units (FMUs), from over 170 in Tokat, were randomly selected using 50% sampling. The sample size was determined among the subjects aged ≥20 who registered with the FMUs, due to gender, age group, and the urban/rural population size of Tokat using the stratified cluster sampling method. Subjects were invited to the FMUs. A questionnaire was performed face to face. The blood samples were taken, and anti-CCHFV IgG antibodies were measured with ELISA method. RESULTS: 1272 (54.9%) out of 2319 participants were female, and the mean age was 47.3 ± 15.3. Anti-CCHFV IgG seropositivity was 5.6% (n = 130). Seropositivity rates in terms of adjusted odds ratios (AOR) were higher 2.53 times (95% CI: 1.57-4.08; p=0.001) in males; 4.05 (95% CI: 2.14-7.65; p < 0.001) in age group ≥65; 0.33 (95% CI: 0.14-0.76; p < 0.001) in graduates of high school and above; 0.71 (95%CI: 0.33-1.52; p < 0.001) in ones with good income; 1.84 (95%CI: 1.18-2.86; p < 0.001) in farmers; 1.64 (95% CI: 1.04-2.27; p < 0.001) in people dealing with animal husbandry; and 1.02 (95% CI: 1.03-2.29; p < 0.001) in those with history of tick contact. CONCLUSIONS: CCHF seroprevalence is still a common public health problem in Tokat, Turkey. Male gender, advanced age group, low-educated, low-income, farmers, animal husbandry, and history of tick contact were found to be risk factors for CCHF. The importance of this kind of community-based studies to identify the seroprevalence in regional and national level increases even more.
RESUMEN
PURPOSE: Knowledge regarding patients' clinical condition at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection is sparse. Data in the international, multicenter Lean European Open Survey on SARS-CoV-2-Infected Patients (LEOSS) cohort study may enhance the understanding of COVID-19. METHODS: Sociodemographic and clinical characteristics of SARS-CoV-2-infected patients, enrolled in the LEOSS cohort study between March 16, 2020, and May 14, 2020, were analyzed. Associations between baseline characteristics and clinical stages at diagnosis (uncomplicated vs. complicated) were assessed using logistic regression models. RESULTS: We included 2155 patients, 59.7% (1,287/2,155) were male; the most common age category was 66-85 years (39.6%; 500/2,155). The primary COVID-19 diagnosis was made in 35.0% (755/2,155) during complicated clinical stages. A significant univariate association between age; sex; body mass index; smoking; diabetes; cardiovascular, pulmonary, neurological, and kidney diseases; ACE inhibitor therapy; statin intake and an increased risk for complicated clinical stages of COVID-19 at diagnosis was found. Multivariable analysis revealed that advanced age [46-65 years: adjusted odds ratio (aOR): 1.73, 95% CI 1.25-2.42, p = 0.001; 66-85 years: aOR 1.93, 95% CI 1.36-2.74, p < 0.001; > 85 years: aOR 2.38, 95% CI 1.49-3.81, p < 0.001 vs. individuals aged 26-45 years], male sex (aOR 1.23, 95% CI 1.01-1.50, p = 0.040), cardiovascular disease (aOR 1.37, 95% CI 1.09-1.72, p = 0.007), and diabetes (aOR 1.33, 95% CI 1.04-1.69, p = 0.023) were associated with complicated stages of COVID-19 at diagnosis. CONCLUSION: The LEOSS cohort identified age, cardiovascular disease, diabetes and male sex as risk factors for complicated disease stages at SARS-CoV-2 diagnosis, thus confirming previous data. Further data regarding outcomes of the natural course of COVID-19 and the influence of treatment are required.

Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.

Mortality rates of Crimean-Congo hemorrhagic fever (CCHF) vary from 5% to 80%. However, there is no clear information available about why this disease is fatal for some people while others recover. In this study, the factors related to fatalities and serious clinical progression of CCHF patients and the correlation between serious prognosis and IL 28-B gene polymorphism were investigated. The study included 107 patients with a preliminary diagnosis of CCHF, and the patients were found positive for CCHFV RNA based on polymerase chain reaction (PCR) analysis. The IL 28-B rs12979860 polymorphism was identified by PCR "restriction fragment length polymorphism" (PCR-RFLP) analysis using blood samples from the patients. In addition to the IL 28-B analysis results, a variety of data along with laboratory records obtained during the hospital stay were evaluated using statistical analysis. Of the 107 cases, nine were fatal (8.4%), while the other patients recovered and were discharged. Twenty-four patients had the CC genotype (22.43%), 64 had the CT genotype (59.81%), and 19 had the TT genotype (17.76%). Of the nine patients who died, three had the CC genotype (33.33%) and six had the CT genotype (66.67%). None of the patients who died had the TT genotype. Symptoms and findings of diarrhea, abdominal pain, hemorrhage, and rash were more common in fatal cases than in non-fatal cases. The IL 28-B rs12979860 polymorphism was not found to have a statistically significant correlation with fatality or symptoms indicating serious clinical progression in CCHF patients. As has been observed in previous studies, our study showed that leukocytosis, abdominal pain and diarrhea were more common in fatal cases.

Crimean-Congo hemorrhagic fever (CCHF) is an acute viral hemorrhagic fever caused by Crimean Congo hemorrhagic fever virus (CCHFV). Paraoxonase-1 (PON1) is a high density lipoprotein (HDL)-binding protein which defense the body against oxidative stress. To investigate the role of the PON1 gene in CCHF, we screened the genotypes of two single nucleotide polymorphisms (Q192R [rs662] and L55M [rs854560]) in CCHF patients stratified according to course of severity and mortality by using PCR-based RFLP assay. Overall, 132 patients diagnosed as CCHF were enrolled in this study. The frequencies of the three genotypes and two alleles of Q192R and L55M polymorphisms didn't show any statistically significant differences in terms of mortality and disease severity (pâ¯>â¯0.05). Any statistically significant differences were not found between severe and mild and fatal and non-fatal CCHF patients according to seven composite genotypes (pâ¯>â¯0.05). When we analyzed the clinical characteristics of CCHF patients stratified according to PON1gene polymorphisms, any statistically significant differences were not also observed (pâ¯>â¯0.05). Our study showed no possible association between genotypes of PON1 gene Q192R and L55M polymorphisms and CCHF.

INTRODUCTION: Patients with hematological malignancies, who are in the high risk group for infectious complications and bacterial bloodstream infections. The aim of the study evaluated epidemiology and mortality in bacterial bloodstream infections in patients with hematologic malignancies. In addition to determine the risk factors, changes in the distribution and frequency of isolated bacterias. METHODOLOGY: In this retrospective study. There were investigated data from 266 patients with hematological malignancies and bacterial bloodstream infections who were hospitalized between the dates 01/01/2012 and 12/31/2017. RESULTS: There were 305 blood and catheter cultures in febrile neutropenia attacks in total. In these total attacks, primary bloodstream infections were 166 and catheter-related bloodstream infections were 139. In blood cultures; Escherichia coli and Klebsiella pneumoniae bacteria were detected in 58,0% and 22,9% of the samples, respectively. 52,4% of the cultured Gram-negative bacterias were extended spectrum beta-lactamase (ESBL). Carbapenemase positive culture rate was 17,2% in Gram-negative bacteria cultures. Staphylococcus epidermidis was found in 38,4% of the Gram-positive bacteria cultures. In Gram-positive bacteria; methicillin resistance were detected in 82,2% of the samples. There was a statistically significant relationship between bloodstream infection and disease status. 60 patients with primary bloodstream infections were newly diagnosed. CONCLUSIONS: In patients with hematological malignancies, certain factors in the bloodstream infections increase the mortality rate. With the correction of these factors, the mortality rate in these patients can be reduced. The classification of such risk factors may be an important strategy to improve clinical decision making in high-risk patients, such as patients with hematological malignancies.

Crimean-Congo haemorrhagic fever (CCHF) is a viral zoonotic disease which can lead to life-threatening with haemorrhagic manifestations. We aimed here in this study was to evaluate the effect of the platelet count and volume-related indices, such as the mean platelet volume (MPV), platelet distribution width (PDW) which is a measure of platelet anisocytosis and plateletcrit, in the haemorrhagic manifestations and mortality seen in CCHF cases. We retrospectively examined data derived from 173 patients. The age, gender, alanine transaminase (ALT), aspartate transaminase (AST), platelet counts and MPV, PDW and PCT values upon admission (MPV1, PDW1 and PCT1) and those values measured at the time when the PLT was at the lowest level (MPV2, PDW2 and PCT2), haemorrhagic manifestations and the mortality status of patients diagnosed with CCHF were recorded. ALT and AST values were higher among the haemorrhagic patients when compared with the others (p<0.001), while platelet 1 (PLT1), platelet 2 (PLT2), plateletcrit 1 (PCT1), plateletcrit 2 (PCT2) and platelet distribution width 2 (PDW2) values were significantly lower (p=0.001, p<0.001, p=0.002, p<0.001 and p=0.003, respectively). A negative correlation was documented between haemorrhage and the PLT1, PLT2, PCT1, PCT2 and PDW2 (r=-0.255, r=-0.415, r=-0.241, r=-0.377, r=-0.223, respectively); however, there was a positive correlation between haemorrhage and mortality (r=0.34). This was the first study evaluating the platelet functions in CCHF, such as the PLT, PDW and PCT, in CCHF correlated with the mortality and haemorrhagic manifestations. The platelet functions contribute as much to the prediction of haemorrhage and mortality as the PLT. The present study suggests that the PCT and PDW values could be beneficial in anticipating the inclination toward haemorrhage and mortality.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease. We aimed to investigate the cutaneous manifestations of CCHF and reveal their associations with fatality. Two hundred and sixty-nine patients diagnosed with CCHF were assessed. Skin findings were observed in 170 (63.2%) patients. A facial rash was the most common cutaneous finding (n = 82, 30.5%). In severe cases, hemorrhagic cutaneous manifestations (petechiae and ecchymoses) were recognized. A statistically significant correlation was obtained between cutaneous manifestations and fatality, and it was determined that there was a strong positive correlation between fatality and ecchymosis (r = 567, p < 0.001). In addition, a logistic regression analysis was performed, and death occurred 4.69 times more in those with skin signs than in those without. We hypothesize that CCHF patients with ecchymosis are at the highest risk and that cutaneous findings can contribute to the prognosis of CCHF.

OBJECTIVES: Crimean-Congo Hemorrhagic Fever (CCHF) is a fatal, tick-borne disease. The classic clinical presentation of CCHF is characterized by sudden onset of high fever, chills, and severe headache. There are no previous reports on the characteristics of headaches caused by CCHF. Therefore, we investigated the relationship between CCHF-induced headache and the clinical course of the disease. METHODS: We included 60 patients with headache diagnosed with CCHF; they were divided into two groups: group 1 included patients with hospital stay <7 days and group 2 included patients with hospital stay >7 days. The control group included 43 viral pneumonia patients with headache. Patients described the characteristics of headaches and also self-rated the severity with a numeric pain scale that classified headache as either mild or severe. RESULTS: In the group with CCHF, 66.7% of the reported headaches met criteria for diagnosis of migraine. This ratio was significantly higher than that in the control group (37.5%). The headache severity scores in group 1 were lower than those in group 2. The hospitalization length was shorter (p=0.004) and the platelet levels were higher in CCHF patients with mild headache compared with CCHF patients with severe headache (p=0.005). CONCLUSION: CCHF patients had more often and severe headaches than the controls. The severity of headache may be associated with the severity of vascular endothelial damage, vasodilatation, and abnormal release of inflammatory cytokines in CCHF similar in migraine. Most CCHF patients experienced migraine-like headaches, suggesting that cerebral vessel involvement might be important in both CCHF and migraine.

- 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.

INTRODUCTION: Bloodstream infection (BSI) caused by Enterobacteriaceae is associated with mortality in cancer patients receiving chemotherapy. The aim of this study is to identify the risk factors and outcomes related to BSIs caused by extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in cancer patients. METHODOLOGY: Hematology/oncology patients, who were diagnosed with BSIs caused by Enterobacteriaceae by positive blood cultures were evaluated retrospectively. Patients were divided into two groups by ESBL-positive and ESBL-negative Enterobacteriaceae bacteremia. Patients' demographic features, underlying conditions, comorbidity, neutrophil count, duration of neutropenia, antibiotic use in the previous three months before infection, mechanical ventilation, steroid use, central venous catheter implementation, total parenteral nutrition (TPN), hospitalization in the past three months, stay in intensive care unit, quinolone prophylaxis, and history of infection with ESBL-producing Enterobactericeae were evaluated. Risk factors related to BSIs caused by ESBL-producing Enterobacteriaceae and mortality were assessed. RESULTS: A total of 122 patients were evaluated retrospectively. Quinolone propyhlaxis, TPN, infection with Extended Spectrum Beta-Lactamase positive ESBL-P Enterobacteriaceae during the previous three months, treatment with piperasillin-tazobactam or carbapenems in the previous three months were found to be independent risk factors for ESBL-P BSIs. Longer duration of neutropenia before BSI and complication at the beginning of BSI were found to be independent risk factors for mortality related to infection. CONCLUSIONS: ESBL-producing Enterobacteriacea should be treated with an appropriate antibiotic that is associated with better outcomes in hematology/oncology patients with BSIs. History of broad-spectrum antibiotic use and stay in hospital in the previous three months should be taken into consideration upon commencing antibiotic therapy.
RESUMEN
INTRODUCTION: Crimean-Congo Hemorrhagic Fever (CCHF) can also be transmitted through unprotected contact directly with blood or body fluids as well as from laboratories. This study aimed to determine the seroprevalence of CCHF disease in the employees of the State Hospital of Yozgat Province, located in Central Anatolia of Turkey, and also to present the risk factors for healthcare workers. METHODOLOGY: A total of 112 volunteer employees of Yozgat State Hospital were included in the study. The study volunteers were divided into two groups: one having had a contact with CCHF patients and patient's samples and the other a non-contact group. RESULTS: In the contact group, 2 (2.9%) out of 67 subjects tested positive for anti-CCHF IgG; however, in the non-contact group, none of the subjects tested positive (Fisher's exact test p > 0.05). Of the two employees who tested positive, one was working at the microbiology laboratory and the other was from the emergency department. CONCLUSION: Although cases of nosocomial transmission of CCHF have been reported previously, questions on the mode of transmission of the disease are still unanswered. The risk factors for the disease should, therefore, be identified in order to take the necessary measures.
RESUMEN
PURPOSE: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease can result in mortality varying from 3.0% to 50.0%. In this study, we wished to discuss computed tomography (CT) findings together with clinical and laboratory findings in patients who had disease-related neurological signs. MATERIALS AND METHODS: The study included patients who were diagnosed with CCHF. Seventeen patients that had neurological signs were enrolled as the patient group. As a control group, 40 patients diagnosed with CCHF and did not have neurological signs were enrolled. Patients who had neurological signs were examined with brain CT. Radiological and clinical findings of both groups were compared. RESULTS: There were pathological findings in three patients while brain CT's of 14 patients were evaluated as normal. Blood urea nitrogen, lactate dehydrogenase, creatine kinase, total bilirubin, neutrophil, activated partial thromboplastin time, and C-reactive protein levels were significantly higher in the group with neurological signs whereas platelet count and calcium levels were significantly lower in this group. Six of 57 patients died during the follow-up period. Six patients who died were in the group, in which central nervous system (CNS) imaging study was performed. CONCLUSION: As the presence of CNS signs is a bad prognostic indicator in CCHF, they should be investigated carefully.

BACKGROUND: Crimean Congo Hemorrhagic Fever (CCHF) is a life threatening acute viral infection that presents significant risk of nosocomial transmission to healthcare workers. AIM: Evaluation of CCHF infection prevention and control (IP&C) practices in healthcare facilities that routinely manage CCHF cases in Eurasia. METHODS: A cross-sectional CCHF IP&C survey was designed and distributed to CCHF centers in 10 endemic Eurasian countries in 2016. RESULTS: Twenty-three responses were received from centers in Turkey, Pakistan, Russia, Georgia, Kosovo, Bulgaria, Oman, Iran, India and Kazakhstan. All units had dedicated isolation rooms for CCHF, with cohorting of confirmed cases in 15/23 centers and cohorting of suspect and confirmed cases in 9/23 centers. There was adequate personal protective equipment (PPE) in 22/23 facilities, with 21/23 facilities reporting routine use of PPE for CCHF patients. Adequate staffing levels to provide care reported in 14/23 locations. All centers reported having a high risk CCHFV nosocomial exposure in last five years, with 5 centers reporting more than 5 exposures. Education was provided annually in most centers (13/23), with additional training requested in PPE use (11/23), PPE donning/doffing (12/23), environmental disinfection (12/23) and waste management (14/23). CONCLUSIONS: Staff and patient safety must be improved and healthcare associated CCHF exposure and transmission eliminated. Improvements are recommended in isolation capacity in healthcare facilities, use of PPE and maintenance of adequate staffing levels. We recommend further audit of IP&C practice at individual units in endemic areas, as part of national quality assurance programs.

Invasive pulmonary aspergillosis is most commonly seen in immunocompromised patients. Besides, skin lesions may also develop due to invasive aspergillosis in those patients. A 49-year-old male patient was diagnosed with acute myeloid leukemia. The patient developed bullous and zosteriform lesions on the skin after the 21st day of hospitalization. The skin biopsy showed hyphae. Disseminated skin aspergillosis was diagnosed to the patient. Voricanazole treatment was initiated. The patient was discharged once the lesions started to disappear.
