The cardioprotective effects of perindopril in a model of polymicrobial sepsis: The role of radical oxygen species and the inflammation pathway.

Mortality rates associated with myocardial dysfunction due to sepsis and septic shock are generally high across the world. The present study focused on the antioxidant and anti-inflammatory effects of perindopril (PER) for the purpose of preventing the adverse effects of sepsis on the myocardium and developing new alternatives in treatment. The control group received only saline solution via the oral route for 4 days. The second group underwent cecal ligation puncture (CLP), and the third underwent CLP and received PER (2 mg/kg). Rats in the third group received 2 mg/kg PER per oral (p.o.) from 4 days before induction of sepsis. Thiobarbituric acid reactive species (TBARS), total thiol (-SH), interleukin-1 beta (IL-1ß), IL-6, 8-hydroxy-2'-deoxyguanosine (8-OHdG), and nuclear factor kappa B (NF-κB/p65) levels increased in the CLP groups. In contrast, PER (2 mg/kg) decreased the levels of biochemical parameters other than total-SH and decreased 8-OHdG, NF-κB/p65 immunopositivity in rat heart tissues. The data from this study show that impairment of the oxidant/antioxidant balance and inflammatory cytokine levels in favor of inflammation in heart tissue under septic conditions results in severe tissue damage. PER administration before sepsis was shown to exhibit antioxidant and anti-inflammatory properties by reducing these effects. This in turn increased the importance of PER as new evidence of its protective effects in heart tissue.

Influenza vaccination rates, knowledge, attitudes and behaviours of healthcare workers in Turkey: A multicentre study.

AIM: Influenza vaccination is the most effective method in prevention of influenza disease and its complications. Our study aimed to investigate the rates of vaccination and the behaviours and attitudes against the vaccine in healthcare workers in Turkey. METHODS: This multicentre national survey is a descriptive study in which 12 475 healthcare workers. Healthcare workers were asked to answer the questionnaire consisting of 12 questions via the survey. RESULTS: It was found that 6.7% of the healthcare workers regularly got vaccinated each year and that 55% had never had the influenza vaccine before. The biggest obstacle against getting vaccinated was determined as not believing in the necessity of the vaccine (53.1%). CONCLUSION: The rates of influenza vaccination in healthcare workers in Turkey are quite low. False knowledge and attitudes on the vaccine and disease are seen as the most important reasons to decline vaccination. It is important to detect reasons for anti-vaccination and set a course in order to increase the rates of vaccination.

Diagnostic value of Chest CT and Initial Real-Time RT-PCR in COVID-19 Infection.

OBJECTIVES: To evaluate the diagnostic value of the rtRT-PCR test and CT in patients presenting with typical clinical symptoms of COVID-19. METHODS: The study with the participation of four center in Turkey was performed retrospectively from 20 March-15 April 2020 in 203 patients confirmed for COVID-19. The initial rtRT-PCR test was positive in 142 (70.0%) of the patients (Group-I) and negative in 61 patients (Group-II). RESULTS: The mean age of the patients in Group-I was 49.7±18.0 years and the time between the onset of symptoms and admission to the hospital was 3.6±2.0 days; whereas the same values for the patients in Group-II were 58.1±19.9 and 5.3±4.2, respectively (p=0.004; p=0.026). Initial rtRT-PCR was found positive with 83.5% sensitivity and 74.1% PPV in patients with symptom duration of less than five days. It was found that rtRT-PCR positivity correlated negatively with the presence of CT findings, age, comorbidity, shortness of breath, and symptom duration, while rtRT-PCR positivity correlated positively with headache. Presence of CT findings was positively correlated with age, comorbidity, shortness of breath, fever, and the symptom duration. CONCLUSIONS: It should be noted that a negative result in the rtRT-PCR test does not rule out the possibility of COVID-19 diagnosis in patients whose symptom duration is longer than five days, who are elderly with comorbidities and in particular who present with fever and shortness of breath. In these patients, typical CT findings are diagnostic for COVID-19. A normal chest CT is no reason to loosen up measures of isolation in patients with newly beginning symptoms until the results are obtained from the PCR test.

The prognostic significance of serum troponin T levels in Crimean-Congo hemorrhagic fever patients.

Crimean-Congo Hemorrhagic Fever (CCHF) is a disease transmitted by the Crimean-Congo hemorrhagic fever virus (CCHFV), characterized by severe fever and hemorrhage and with a reported fatality level of 3-30%. Cerebral hemorrhage, gastrointestinal hemorrhage, severe anemia, shock, myocardial infarction, pulmonary edema, and pleural effusion may be seen as causes of death. Cardiac troponin T (cTn-T) is a biochemical marker with high sensitivity and specificity in myocardial injury. The purpose of this study was to determine the prognostic significance of serum troponin T levels in CCHF patients. Patients hospitalized with a diagnosis of CCHF and whose serum cTn-T was investigated were examined retrospectively. Patients were divided into two groups on the basis of presence or absence of hemorrhage. Data were subjected to statistical analysis. One hundred thirty-five CCHF patients and 72 control subjects were included. Hemorrhage was present in 48 (35.6%) patients. Mean serum cTn-T level was 17.3 ± 28.0 ng/L in the patients with hemorrhage, 9.98 ± 5.97 ng/L in the non-hemorrhage patients (P = 0.001) and 6.6P = 2.6 ng/L in the control samples (P < 0.001). At a cTn-T level cut-off point of 9 ng/L, area under the ROC curve was 0.797 (95%CI: 0.730-0.854), sensitivity 83.0%, specificity 87.5%, PPD 95.7%, and NPV 60.3%. At logistic regression analysis, a rise in cTn-T level above 14 ng/L increased the probability of hemorrhage in CCHF patients approximately threefold. An increased troponin T level may be a prognostic risk factor for hemorrhage in CCHF patients. This marker should therefore be borne in mind in determining treatment strategy in these patients. J.

The prognostic significance of serum TGF-ß1 levels in patients with Crimean-Congo hemorrhagic fever.

Crimean-Congo Hemorrhagic Fever (CCHF) may exhibit a mild clinical course or a severe profile like mortal bleeding. The pathogenesis of the illness and reason of bleeding are unclear. However, endothelial injury is a key factor in the pathogenesis of the illness. Transforming growth factor beta (TGF-ß) is one of the materials involved in repairing injured endothelium. This is a significant polypeptide released in pretty much all cells and important for the regulation of cellular events, epithelium formation, inflammation, blood coagulation, and collagen synthesis. This study aimed to determine the prognostic significance of serum TGF-ß1 levels in CCHF patients. We examined 120 patients hospitalized with CCHF diagnosis and their serum TGF-ß1 was investigated, retrospectively. Patients were put into two groups according to the existence of hemorrhage. Forty-four (36.7%) patients had hemorrhage. TGF-ß1 levels in patients with bleeding were 5.2 ± 1.8, and 7.1 ± 2.2 for non-bleeding (P < 0.0001). When ROC analysis was performed in patients with CCHF alone in order to identify patients with bleeding, at a TGF-ß1 cut-off point of 4.9, AUC was 0.762 (0.675-0.835), sensitivity 59.1%, specificity 85.5%, PPV 70.3%, and NPV 78.3%. We summarize that TGF-ß1 level and endothelial dysfunction can be related. A decreased TGF-ß1 level is a likely prognostic and diagnostic factor for bleeding in CCHF patients. Therefore, this marker should be considered in the treatment strategy for these patients. J. Med. Virol. 89:413-416, 2017. © 2016 Wiley Periodicals, Inc.

Prognostic impact of platelet distribution width in patients with Crimean-Congo hemorrhagic fever.

Platelet distribution width (PDW) is a readily available blood test involving calculations performed by automated blood analyzers. Crimean-Congo hemorrhagic fever (CCHF) may exhibit a severe profile with fatal hemorrhaging or else present with a mild clinical process. The purpose of our study was to investigate the importance of PDW in CCHF patients and its clinical prognostic value. This study was conducted with patients with CCHF. Patients were divided into two groups on the basis of presence or absence of bleeding. Demographic characteristics, clinical findings, PDW, and other laboratory tests were recorded onto forms. A total of 423 patients were included. Hemorrhaging was observed in 27.9% during hospitalization. PDW on the first day of hospitalization was 17.2 ± 0.9% in the hemorrhagic patients and 17.1 ± 0.6% in the cases without hemorrhage (P = 0.290). On the third day of hospitalization, PDW was 17.6 ± 0.8% in the hemorrhagic patients and 17.0 ± 0.7% in the cases without hemorrhage (P < 0.001). At a third-day PDW level cut-off point of 17.1%, AUROC was 0.677, sensitivity 65.5%, specificity 54.6%, PPV 35.5%, and NPV 80.6%. A one-unit raise in third day PDW stepped up the probability of bleeding in patients with CCHF 3.45-fold at logistic regression analysis. This study shows that PDW is a parameter that may be used to determine disease severity. This parameter may be at least as useful as platelet count in helping clinicians identify severe cases. Early identification of cases with a severe course will make it possible to provide early planning of modalities such as intensive care support. J. Med.

An assessment of ventilator-associated pneumonias and risk factors identified in the Intensive Care Unit.

OBJECTIVES: Ventilator-associated pneumonia (VAP) is a significant cause of hospital-related infections, one that must be prevented due to its high morbidity and mortality. The purpose of this study was to evaluate the incidence and risk factors in patients developing VAP in our intensive care units (ICUs). METHODS: This retrospective cohort study involved in mechanically ventilated patients hospitalized for more than 48 hours. VAP diagnosed patients were divided into two groups, those developing pneumonia (VAP(+)) and those not (VAP(-)).\. RESULTS: We researched 1560 patients in adult ICUs, 1152 (73.8%) of whom were mechanically ventilated. The MV use rate was 52%. VAP developed in 15.4% of patients. The VAP rate was calculated as 15.7/1000 ventilator days. Mean length of stay in the ICU for VAP(+) and VAP(-) patients were (26.7±16.3 and 18.1±12.7 days (p<0.001)) and mean length of MV use was (23.5±10.3 and 12.6±7.4 days (p<0.001)). High APACHE II and Charlson co-morbidity index scores, extended length of hospitalization and MV time, previous history of hospitalization and antibiotherapy, reintubation, enteral nutrition, chronic obstructive pulmonary disease, cerebrovascular disease, diabetes mellitus and organ failure were determined as significant risk factors for VAP. The mortality rate in the VAP(+) was 65.2%, with 23.6% being attributed to VAP. CONCLUSION: VAPs are prominent nosocomial infections that can cause considerable morbidity and mortality in ICUs. Patient care procedures for the early diagnosis of patients with a high risk of VAP and for the reduction of risk factors must be implemented by providing training concerning risk factors related to VAP for ICU personnel, and preventable risk factors must be reduced to a minimum.

Mediastinitis and subcutaneous abscess complicated after EBUS-TBNA of 2R mediastinal lymph node.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUSTBNA) is a minimally invasive diagnostic tool used for the evaluation of mediastinal lymphadenopathy. It is a safe procedure, but complications such as bleeding and infection may occur. We report a case of a patient who developed a subcutaneous abscess abscess and mediastinitis after EBUSTBNA. A 75-year-old male with a history of right nephrectomy due to renal cell carcinoma and lung adenocarcinoma history underwent EBUS-TBNA for the evaluation of a right upper paratracheal lymph node. Two weeks after the procedure, the patient presented to the emergency department with skin induration and erythema on the right clavicular area. A non-contrast neck and thorax CT scan was performed, which revealed an extensive subcutaneous abscess on the right clavicular area, extending to the supraclavicular region. The patient was hospitalized, and empirical intravenous antibiotics were initiated due to deep neck infection. Repeated drainage of the subcutaneous abscess was performed. Bacteriologic examination revealed Streptococcus mitis. The patient showed improvement with antibiotic treatment, and a follow-up ultrasound showed a decrease in the size of the abscess and was discharged approximately four weeks after hospitalization. Although very rare, serious infectious complications may develop after EBUSTBNA, and our case report is an important example regarding its management process.

COVID 19 disease independently predicted endothelial dysfunction measured by flow-mediated dilatation.

The systemic effects of COVID-19 disease are still largely uncertain and needs to be scrutinized with further trials. Endothelial dysfunction (ED) is responsible for the majority of adverse cardiovascular events. Flow-mediated dilation (FMD) is easily obtainable method to assess ED accurately. It is aimed to evaluate ED by measuring FMD following COVID-19 disease. Patients diagnosed with COVID-19 disease were recruited to the hospital two month after the discharge. Sex and age-matched healthy subjects were determined as the control group. Blood samples and FMD measurements were obtained from each participant. All subjects were divided into two groups according to the presence of ED determined by FMD measurements. These two groups were compared in terms of demographic features and the presence of recovered COVID-19 disease. A total of 92 subjects consisting of 59 without ED and 33 with ED were included in the study. ED (+) group was older (p = 0.015) and more likely to have hypertension (p = 0.044) and COVID-19 rate was higher in ED (+) group (p = 0.009). While neutrophil count (p = 0.047) and CRP (p = 0.036) were higher, eGFR (p = 0.044) was lower in ED (+) group. In the backward multivariable regression analysis, COVID-19 disease [OR = 3.611, 95% CI 1.069-12.198, p = 0.039] and BMI [OR = 1.122, 95% CI 1.023-1.231, p = 0.015] were independent predictors of ED. COVID-19 disease may cause ED which is the major underlying factor of cardiovascular diseases. Furthermore, COVID-19 disease may deteriorate the existing cardiovascular disease course. Detecting ED in the early phase or preventing by new treatment modalities may improve short and long-term outcome.

The Role of CO-RADS Scoring System in the Diagnosis of COVID-19 Infection and its Correlation with Clinical Signs.

BACKGROUND: Computed tomography (CT) evaluation systematics has become necessary to eliminate the difference of opinion among radiologists in evaluating COVID-19 CT findings. INTRODUCTION: The objectives of this study were to evaluate the efficiency of CO-RADS scoring system in our patients with COVID-19 as well as to examine its correlation with clinical and laboratory findings. METHODS: The CO-RADS category of all patients included in the study was determined by a radiologist who did not know the rtRT-PCR test result of the patients, according to the Covid-19 reporting and data system of Mathias Prokop et al. Results: A total of 1338 patients were included. CT findings were positive in 66.3%, with a mean CO-RADS score of 3,4 ± 1,7. 444 (33.1%) of the patients were in the CO-RADS 1-2, 894 (66.9%) were in the CO-RADS 3-5 group. There were positive correlations between CO-RADS score and age, CMI, hypertension, diabetes mellitus, chronic pulmonary diseases presence of symptoms, symptom duration, presence of cough, shortness of breath, malaise, CRP, and LDH, while CORADS score was negatively correlated with lymphocyte count. The results of the ROC analysis suggested that those with age ≥40 years, symptom duration >2 days, CMI score >1 and/or comorbid conditions were more likely to have a CO-RADS score of 3-5. CONCLUSION: The CO-RADS classification system is a CT findings assessment system that can be used to diagnose COVID-19 in patients with symptoms of cough, shortness of breath, myalgia and fatigue for more than two days.

Screening of Antimicrobial Resistance Genes and Epidemiological Features in Hospital and Community-Associated Carbapenem-Resistant Pseudomonas aeruginosa Infections.

INTRODUCTION: Researching carbapenem-resistant isolates enables the identification of carbapenemase-producing bacteria and prevents their spread. METHODS: P. aeruginosa isolates were recovered from Medicine Faculty of Recep Tayyip Erdogan University and identified by conventional methods and the automated Vitek 2 Compact system. Antimicrobial susceptibility experiments were performed in accordance with CLSI criteria and the automated Vitek 2 Compact system. The PCR method was investigated for the presence of ß-lactamase resistance genes. PFGE typing was performed to show clonal relation among samples. RESULTS: Seventy P. aeruginosa isolates were isolated from seventy patients. Of the patients, 67.1% had contact with the health service in the last 90 days and 75.7% of the patients had received antimicrobial therapy in the previous 90 days. Twenty-four isolates were carbapenem resistant, 2 isolates were multidrug-resistant except colistin, and none of the samples had colistin resistance. The gene encoding ß-lactamase or metallo-ß-lactamase was found in a total of 36 isolates. The bla VEB and bla PER genes were identified in 1 and 5 isolates alone or 17 and 13 isolates in combination with other resistance genes, respectively. The bla NDM was the most detected metallo-ß-lactamase encoding gene (n=18), followed by bla KPC (n=12). bla IMP and bla VIM were detected in 5 and 1 isolates, respectively. Also, the association of bla VEB-bla PER and bla VEB-bla KPC-bla NDM was found to be very high. Much more resistance genes and co-occurrence were detected in hospital-acquired samples than community-acquired samples. No difference was found between the community and hospital-associated isolates according to PFGE results. Simultaneously from 6 patients, other microorganisms were also isolated and 5 of them died. CONCLUSION: The average length of stay (days) was found to be significantly higher in HAI group than CAI group. The death of 5 patients with fewer or no resistance genes showed that the co-existence of other microorganisms in addition to resistance genes was important on death.

The Protective Effects of Perindopril Against Acute Kidney Damage Caused by Septic Shock.

Acute kidney injury (AKI) resulting from septic shock caused by sepsis is an important health problem encountered at rates of 55-73%. Increasing oxidative stress and inflammation following sepsis is a widely observed condition with rising mortality rates. The purpose of this study was to determine whether perindopril (PER) can prevent sepsis-associated AKI with its antioxidant, anti-inflammatory, and anti-apoptotic effects. The control group received an oral saline solution only for 4 days. Cecal ligation and puncture (CLP)-induced sepsis only was applied to the CLP group, while the CLP + PER (2 mg/kg) received CLP-induced sepsis together with 2 mg/kg PER via the oral route for 4 days before induction of sepsis. Finally, all rats were euthanized by anesthesia and sacrificed. TBARS, total SH levels and NF-κß, TNF-α, and Caspase-3 expression were then calculated for statistical analysis. TBARS, total SH, NF-kß/p65, TNF-a, and Caspase-3 levels increased in the CLP group. In contrast, oral administration of PER (2 mg/kg) to septic rats reduced TBARS levels and NF-kß/p65, TNF-α, and Caspase-3 immunopositivity at biochemical analysis. PER treatment appears to be a promising method for preventing sepsis-induced acute kidney injury through its antioxidant anti-inflammation and anti-apoptotic activities.

COVID-19 infection produces subarachnoid hemorrhage; acting now to understand its cause: A short communication.

In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36-54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection. Its early recognition of the patient with spontaneous SAH is imperative.

Comparison of two pandemics: H1N1 and SARS-CoV-2.

OBJECTIVE: We aimed to compare the clinical, epidemiological, and prognostic features of the H1N1 pandemic in 2009 and the severe acute respiratory syndrome coronavirus 2 pandemic in 2020. METHODS: This retrospective study involved subjects from seven centers that were admitted and found to be positive for H1N1 or COVID-19 real-time polymerase chain reaction test. RESULTS: A total of 143 patients with H1N1 and 309 patients with COVID-19 were involved in the study. H1N1 patients were younger than COVID-19 ones. While 58.7% of H1N1 patients were female, 57.9% of COVID-19 patients were male. Complaints of fever, cough, sputum, sore throat, myalgia, weakness, headache, and shortness of breath in H1N1 patients were statistically higher than in COVID-19 ones. The duration of symptoms until H1N1 patients were admitted to the hospital was shorter than that for COVID-19 patients. Leukopenia was more common in COVID-19 patients. C-reactive protein levels were higher in COVID-19 patients, while lactate dehydrogenase levels were higher in H1N1 ones. The mortality rate was also higher in H1N1 cases. CONCLUSIONS: The severe acute respiratory syndrome coronavirus 2 pandemic is a major public health problem that continues to affect the world with its high rate of contagion. In addition, no vaccines or a specific drug for the benefit of millions of people have been found yet. The H1N1 pandemic is an epidemic that affected the whole world about ten years ago and was prevented by the development of vaccines at a short period. Experience in the H1N1 pandemic may be the guide to prevent the COVID-19 pandemic from a worse end.

The protective effects of angiotensin-converting enzyme inhibitor against cecal ligation and puncture-induced sepsis via oxidative stress and inflammation.

AIMS: Sepsis is a severe public health problem affecting millions of individuals, with global mortality rates caused by lower respiratory tract infections are approximately 2.38 million people a year die from respiratory failure caused by infection. Although ACE is known to contribute to damage in septicemia, the pathophysiological mechanisms of sepsis remain unclear. While mortality can be significantly reduced through effective and sensitive antibiotic therapy, antibiotic resistance restricts the use of these drugs, and the investigation of novel agents and targets is therefore essential. Our aim was to determine whether Perindopril (PER) has anti-inflammatory and antioxidant capable of preventing these adverse conditions resulting in injury in previous studies. MAIN METHODS: Sprague Dawley rats were randomly assigned into the control group, received oral saline solution alone for four days. the cecal ligation and puncture (CLP) group, underwent only cecal ligation and puncture induced sepsis, while the CLP + PER (2 mg/kg) underwent cecal ligation and puncture-induced sepsis together with oral administration of 2 mg/kg PER for four days before induction of sepsis. KEY FINDINGS: Malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), Caspase-3 and nuclear factor kappa B (NF-kß/p65) levels increased in the CLP group. On the other hand, PER (2 mg/kg) oral administration to septic rats decreased MDA, TNF-α and increase glutathione (GSH) in the lung tissue. In addition, PER administration also decreased the lung tissue NF-κB and Caspase-3 immunopositivity against sepsis. SIGNIFICANCE: PER treatment may represent a promising means of preventing sepsis-induced lung injury via antioxidant and anti-inflammation effects.

The relationship between diagnostic value of chest computed tomography imaging and symptom duration in COVID infection.

OBJECTIVES: Severe acute respiratory syndrome-coronovirus-2 is a global public health problem, in which early diagnosis is required to prevent the spread of infection. In this study, we aimed to reveal the diagnostic value of chest computed tomography (CT) imaging with respect to symptom duration. METHODS: This retrospective study involved patients from five centers, who were admitted with typical COVID-19 symptoms and found to be positive for COVID-19 real-time reverse transcription-polymerase chain reaction (rtRT-PCR) test. RESULTS: One hundred and five patients with positive COVID-19 rtRT-PCR test were involved in the study. Sixty percent of these patients had chest CT imaging findings consistent with COVID-19 pneumonia. The most common chest CT finding was bilateral and subpleural ground-glass opacity in middle-lower lobes of the lungs. Chest CT findings were detected in 85.1% of the patients with a symptom duration of more than 2 days. In receiver operating characteristic analysis of this parameter, area under the curve (AUC) was 0.869, while sensitivity and specificity were 90.5% and 76.2%, respectively. It was notable that chest CT findings were 7.17 times more common among the patients aged 60 years and older, with AUC, specificity, and positive predictive value of 0.768, 88.1%, and 84.8%, respectively. CONCLUSION: Chest CT imaging is a quite valuable tool in patients with longer than 2 days' duration of symptoms, in whom clinical and epidemiological data support the diagnosis of COVID-19 infection. We suggest that the diagnosis of COVID-19 pneumonia should be made with chest CT imaging when rtRT-PCR test cannot be performed or gives a negative result, which is important for public health and to prevent the spread of infection.

[A brucellosis case with macular rash and peripheral neuropathy]. / Maküler döküntü ve periferik nöropatiyle seyreden bir bruselloz olgusu.

Brucellosis is a significant health problem especially in developing countries as Turkey. Skeletal system involvement is relatively a common complication of human brucellosis, however genitourinary, cardiovascular, neurovascular and skin involvements are less frequent. In this case report, a 36-years-old female patient with fever, arthralgia, disseminated macular rash at the extremities and body and peripheral polineuropathy has been presented. The patient, living at a rural area, had a history of consumption of raw milk products. Polyneuropathy of the patient presenting as glove-sock type paresthesia was evaluated with electromyography and reported as mild demyelinated sensorial polyneuropathy and radiculopathy compatible with right L(4-5) involvement. Brucella agglutination test was found to be positive at a titer of 1/1280 in the serum sample. Other bacterial and viral agents presenting with maculopapular rash were ruled out by serological tests. Bacterial growth was detected in the blood culture by automated BacT/ALERT 3D system (bioMerieux, USA) and the bacteria was identified as Brucella melitensis by automated VITEK-2 system (bioMerieux, France). Microbiologic diagnosis was confirmed by detection of agglutination with polyvalent and monovalent anti-M Brucella sera. The patient was successfully treated with rifampicin and doxycycline combination for six weeks. The macular rash was recruited leaving a brown pigmentation in the first week of treatment, whereas the neurologic signs and symptoms disappeared at the end of the first month. Brucella infection should be considered in the differential diagnosis of skin rash and neurologic disorders especially in endemic areas such as Turkey.

Carbonic anhydrase I-II autoantibodies and oxidative status in long-term follow-up of patients with Crimean-Congo haemorrhagic fever.

CONTEXT: Crimean-Congo haemorrhagic fever (CCHF) is a life-threatening acute febrile haemorrhagic disease. OBJECTIVE: This study was to measure levels of the oxidative stress biomarkers malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) and of CA I-II autoantibodies as biomarkers for autoimmunity and course of disease in patients with CCHF. METHODS: Seventy CCHF patients and 39 healthy control volunteers were included in the study. RESULTS: Serum MDA and TAS levels were significantly higher (p < .0001) and serum TOS and OSI levels were significantly lower (p < .0001) in both the acute period and at 6th-month follow-up in the CCHF patients compared to the healthy volunteers. CA II levels were significantly higher in the acute period compared to the healthy volunteers (p < .005) and were significantly lower at 6th-month follow-up (p < .05). CONCLUSION: Serum MDA and CA II autoantibodies appear to reflect oxidative stress status and disease progression in CCHF and may be used as biomarkers for oxidative stress and disease progression.

Changes in acute viral hepatitis epidemiology in the Turkish adult population: A multicenter study.

BACKGROUND/AIMS: The present study aimed to determine the changes in the epidemiology of hepatitis in recent years in an adult Turkish population. MATERIALS AND METHODS: Overall, 852 patients with acute viral hepatitis from 17 centers were included in this study. Their sociodemographic characteristics, clinical courses, treatments, and laboratory findings were retrospectively analyzed. RESULTS: The most commonly found microorganisms were the hepatitis B virus (55.2%) and hepatitis A virus (37.6%), and the types of acute viral hepatitis differed significantly according to the age group (p≤0.001). The most frequently reported symptom was fatigue (73.7%), and the most common complications were cholecystitis (0.4%) and fulminant hepatitis (0.4%). The median hospital stay was 9 days (range 1-373). In total, 40.8% patients with acute hepatitis B virus developed immunity. CONCLUSION: In Turkey, there are significantly large adolescent and adult populations susceptible to acute viral hepatitis. Therefore, larger vaccination programs covering these age groups should be implemented.

Cost analysis and evaluation of nosocomial infections in intensive care units.

BACKGROUND/AIM: The purpose of this study was to evaluate nosocomial infections occurring in our hospital intensive care units (ICUs) and the risk factors for these, and to determine the effect of these infections on mortality and cost. MATERIALS AND METHODS: This retrospective study was performed via infection control committee surveillance data, ICU records, and information processing data between 1 January and 31 December 2013 at the Kanuni Education and Research Hospital. RESULTS: A total of 309 nosocomial infections were observed in 205 out of 566 patients. The density of nosocomial infections was 25.4 in 1000 patient days. Hospitalization was prolonged, and APACHE II and Charlson comorbidity scores were high in patients developing nosocomial infections (P < 0.001). Of the patients diagnosed with a nosocomial infection, 170 died. Infections were determined as the cause of death in 62 (36.5%) of the nonsurviving patients with a nosocomial infection. Acinetobacter baumannii was identified in 46 (74.2%) of the patients that died from nosocomial infections. The mean cost in patients developing a nosocomial infection was 15,229.30 Turkish lira (TL), compared to 9648.00 TL in patients without a nosocomial infection (P = 0.002). CONCLUSION: Regular infection control education sessions need to be held and the number of nurses needs to be increased in order to be able to reduce this high mortality, morbidity, and cost.
