A strategical re-thinking on National Blood Donor Pool: Anti-HBc positivity related re-entry mechanisms.

BACKGROUND AND OBJECTIVES: Screening of blood donations for antibodies against hepatitis B core antigen (anti-HBc) is used to prevent transfusion transmitted hepatitis B virus (HBV) infection. In this study, we studied the magnitude of blood donor gain by using a re-entry mechanism in our Blood Bank of Gulhane Military Academy of Medicine. MATERIALS AND METHODS: Between January and May 2013, 5148 voluntary blood donors were screened by ELISA method for HBsAg, anti-HBc total and other screening markers, prospectively. Samples with repeated reactivity for the presence of anti-HBc were further tested with four supplemental assays. RESULTS: We detected 515 (10%) anti-HBc positive and 4612 (90%) anti-HBc negative cases in 5127 HBsAg negative serum samples. A total of 461 (89.5%) blood units were reactive for at least one additional serologic parameter and 54 were (10.5%) negative. Isolated anti-HBc positivity rate was 1.3% (69/5127). In the isolated anti-HBc positive samples, 54 were also anti-HBe and HBeAg negative. HBV DNA was not detected in any of the samples. CONCLUSION: Applying the EDQM criteria would decrease our blood donor loss from 10% to 5.4%. As alternative re-entry mechanisms have already been presented in the literature, institution of a new policy is needed to enhance the limited blood donor pool in our system.

[Investigation of the association between paraoxonase-1 gene polymorphisms and response to therapy in chronic hepatitis C patients]. / Kronik hepatit C enfeksiyonu olan hastalarda paraoksonaz-1 gen polimorfizmi ile tedaviye yanit arasindaki iliskinin arastirilmasi

Liver-derived paraoxonase-1 (PON1) enzyme that is found in the circulation is bound to high-density lipoproteins and reduces the amount of oxidized lipids with its antioxidant effect. Humans have at least three different PON gene regions which are adjacent to the other on the 7th chromosome. It has been shown that PON1 gene and its polymorphisms are related with various diseases. It is also known that, hepatitis C virus (HCV) is tightly associated with the cell lipoproteins in each step of its replication cycle leading to modulation of the host lipid metabolism. The aim of this study was to investigate the relationship between the response to chronic hepatitis C (CHC) therapy and aminoacid changes in 55' and 192' regions of PON1 enzyme believed to be involved in the pathophysiology of many chronic diseases. A total of 49 CHC patients (27 male, 22 female; mean age: 52.9 ± 12.6 yrs), all infected with HCV genotype 1b and positive for anti-HCV and HCV-RNA were included in the study. Patients who were HCV-RNA negative at the sixth month following at least once pegilated interferon + ribavirin treatment, were considered as therapy-responders, whereas those who were HCV-RNA positive were considered as non-responders. The genomic DNAs were isolated from patients' blood samples in their routine follow-ups and Q/R192 and L/M55 PON1 polymorphism analysis in 55. and 192. regions was performed by T-ARMS-PCR (Tetra-primer amplification refractory mutation system-polymerase chain reaction) method. In our study, the analysis of PON1 polymorphisms yielded 44.1% of LL, 44.1% of LM and 11.8% of MM genotypes at position 55 and 55.9% of QQ, 41.2% of QR, and 2.9% of RR genotypes at position 192 in therapy-responders. In the evaluation of combined genotype analysis of the patients, there was only one case who was responsive to treatment with LL/RR genotype. Of the patients, eight harbored LL/QQ genotypes and seven of them (87.5%) were responsive to treatment. However, statistical analysis indicated that there was no relationship between PON1 L/M55 and PON Q/R192 polymorphisms and response to CHC treatment (chi-square test, p> 0.05). Our data did not support a relationship between PON1 polymorphisms and response to CHC therapy, in contrast to a few studies pointing out of this correlation. This might be attributed to relatively low number of patients included. In conclusion, since antiviral agents used for CHC therapy are limited and costly, it was thought that further investigations with large numbers of patients should be conducted to establish the presence of any relationship between the response to CHC therapy and genotypes of the PON1 enzyme.

[Comparison of endotracheal aspiration and mini-BAL culture results in the diagnosis of ventilator-associated pneumonia]. / Ventilatörle Iliskili Pnömoni Tanisinda Kullanilan Endotrakeal Aspirat Kültürü ile Mini-BAL Kültürünün Karsilastirilmasi

The objective of this study was to compare the results of cultures obtained by mini-bronchoalveolar lavage (BAL) and endotracheal aspiration (ETA) techniques, used for rapid and accurate determination of pathogens causing ventilator-associated pneumonia (VAP) in intensive care units. Of the 92 patients on mechanical ventilation followed at the emergency intensive care unit of our hospital between June 2010 and June 2011, 30 (32.2%) patients were diagnosed as VAP and they were included in this study. VAP diagnosis were based on the clinical and radiological findings. Clinical pulmonary infection score (CPIS) of > 6 was accepted as the clinical criteria of VAP. Initially ETA samples were collected from the patients followed by mini-BAL sampling 15 minutes later, together with urine and two blood cultures. Microbiological evaluation and identification were performed by conventional methods and Phoenix 100 (BD Diagnostic Systems, ABD) automated system. In quantitative culture analysis, > 10.000 cfu/ml for BAL and > 100.000 cfu/ml for ETA were accepted as the positive result. The mean ages of VAP-developed (n= 30; 18 were male) and nondeveloped (n= 62; 39 were male) patients were 68.23 ± 16.19 and 52.16 ± 10.41 years, respectively, and the mean durations of mechanical ventilation were 29.57 ± 15.78 and 12.11 ± 6.01 days, respectively. Multivariate logistic regression analysis showed that older age (p< 0.001) and duration of mechanical ventilation (p< 0.001) were independent risk factors for VAP development. There was also a statistically significant difference in CPIS values between patients who developed VAP and not (6.8 ± 1.15 and 2.71 ± 1.06, respectively; p< 0.001). The use of CPIS for VAP diagnosis was found to be useful in patients on mechanical ventilation. In our study, a total of 16 strains (six A.baumannii, three P.aeruginosa, one K.pneumoniae, six S.aureus) were isolated from ETA cultures, while 34 strains (16 A.baumannii, six P.aeruginosa, four K.pneumoniae, two E.coli, six S.aureus) were isolated from mini-BAL cultures of 30 VAP patients. The contamination rate for ETA cultures was found as 27% (8/30), however there was no contamination in mini-BAL samples. The rates of negative cultures for ETA and mini-BAL were 20% (6/30) and 7% (2/30), respectively. Seven (87.5%) of the eight contaminated ETA samples, yielded pathogenic bacterial growth (six A.baumannii, one K.pneumoniae) in mini-BAL samples. Similarly, of the six negative ETA samples, 5 (83%) yielded bacterial growth (two E.coli, two K.pneumoniae, one P.aeruginosa) in mini-BAL samples. Statistical analysis with Spearman test indicated no positive correlation between the culture results of mini-BAL and ETA (p= 0.464), and the concordance between the culture results of those methods was found as 50%. It was concluded that the use of mini-BAL instead of ETA samples for the isolation of causative microorganisms of VAP seemed to be more useful due to the high contamination risk in ETA culturing techniques and higher bacterial isolation rates in mini-BAL sampling.

War and infection in the pre-antibiotic era: the Third Ottoman Army in 1915.

BACKGROUND: The aim of this study, which evaluated historical data, was to delineate the probable impacts of infectious diseases on human populations under extraordinary circumstances. The second goal was to disclose the mortality rates for infectious diseases in the absence of antibiotics. METHODS: The Third Ottoman Army records at the Turkish General Staff Military History and Strategic Study Directorate were studied retrospectively for the period between March 1915 and February 1916. RESULTS: For the Third Ottoman Army, the number of infection-related deaths over the single-year period was 23,601. Malaria, relapsing fever and dysentery were the most common infections. In that pre-antibiotic era, the highest mortality rates were seen for cholera (80%), pulmonary tuberculosis (58%) and typhoid fever (51%). However, typhus had the maximum share in soldier deaths (6053 soldiers). The rate of vector-borne infections peaked in the summer of 1915, while the frequency of respiratory tract infections was highest in the colder months. In contrast, gastrointestinal tract infections appeared to maintain a steady state throughout the year. CONCLUSIONS: If the wartime data for 1915 are accepted to provide a model for extraordinary circumstances in the 21st century, vector-borne, respiratory tract and gastrointestinal infections can be accepted as the challenging issues with significant mortality.

[Progressive multifocal leukoencephalopathy in an elderly patient with no obvious immunosuppression]. / Belirlenebilen bir immünyetmezligi olmayan yasli bir hastada gelisen progresif multifokal lökoensefalopati.

Progressive multifocal leukoencephalopathy (PML) which is a severe demyelinating disease of the central nervous system (CNS), is caused by a human polyomavirus known as JC virus (JCV). PML is seen primarily in immunosuppressed (AIDS, organ transplant or malignancy) patients. In this report, a case of PML that developed in a 75-years-old female patient with no known immunosuppression was presented. The patient was admitted to the emergency department with complaints of headache and burning sensation in head. Cerebrospinal fluid (CSF) examination revealed increase in lymphocytic cells. Since lesions compatible with tuberculoma were detected in brain tissue by magnetic resonance imaging, antituberculous therapy initiated empirically. The disease exhibited a progressive course and all the serological, molecular, microbiological and biochemical tests performed in blood and CSF failed to identify the causative agent. Pathological and immunohistochemical examination of the brain biopsy specimens demonstrated demyelinating disease. Brain biopsy, CSF, serum and urine specimens were investigated by real-time polymerase chain reaction specific for JCV and JCV-DNA was detected in the urine samples. Follow-up visits of the patient indicated a progressive course. In conclusion, after ruling out the other primary causes, JCV should be investigated in patients with demyelinating CNS disease even in the absence of significant immunosuppressive condition. Elderly patients should be considered in the risk group for demyelinating disease of CNS due to JCV.

The effect of methylprednisolone on treatment in rats with induced sepsis.

In this study, an appropriate sepsis model was created in rats. Additionally, the effects of steroid treatments on survival, in connection with antibiotic treatment, were investigated. The sepsis model performed via intraperitoneal injection of 3 ml/kg fecal suspension was determined as the most appropriate model for our study. Fifteen rats were used to investigate the effect of piperacillin-tazobactam on sepsis treatment. Forty-five randomly selected rats were used to investigate the efficacy of the antibiotic-plus-steroid combination. The rats were divided into three groups of 15 rats each. Twelve hours after the administration of fecal suspension, methylprednisolone (MP) at the dose of 0.25, 0.5, and 2 mg/kg/day was given to each group, respectively, in addition to an antibiotic administered intravenously. In order to investigate the effect of steroids alone in the treatment of sepsis, 0.5 mg/kg/day MP was given intravenously to 15 rats, 12 h after the fecal suspension was administered. It was concluded that administration of MP alone shortens survival time in rats with sepsis, whereas antibiotic therapy alone increases survival time significantly in rats with sepsis. It was seen that the antibiotic-plus-steroid treatment increases survival significantly compared to rats with no treatment (p < 0.05). In addition, steroids, when added to an antibiotic treatment in sepsis, affect survival positively when compared to the group with antibiotic therapy alone, depending on the dose given. Although, not statistically significant, high doses decrease survival (p > 0.05), and very low doses increase survival and mean survival time (p > 0.05) on the basis of clinical observation and average life time. However, low doses were found to increase survival significantly (p < 0.05). We concluded that low-dose MP, in addition to the appropriate antibiotic therapy, is the optimal in the treatment of rats with intraabdominal sepsis.

[An outbreak of vanA genotype Enterococcus faecium in pediatric clinic of a training hospital]. / Bir egitim hastanesinin çocuk kliniginde vanA genotip Enterococcus faecium salgini.

Vancomycin-resistant enterococci (VRE) have been increasingly reported from most countries around the world following initial isolation from patients in United States and European countries. A vancomycin-resistant Enterococcus faecium (VREF) outbreak was determined by hospital infection control committee in the pediatric unit of Gulhane Military Medical Academy, Ankara, Turkey in the first week of March 2008. While one of the 4 VREF strains was isolated from urine culture of a patient with neuroblastoma, the remaining strains were isolated from cultures of urine and rectal swab samples of a patient with nephrotic syndrome and from the hospital room doorknob of this patient. Aims of this study were to determine antibiotic susceptibilities by E-test, to investigate the presence of vanA, vanB and vanC-2 resistance genes by polymerase chain reaction (PCR), and to genotype the 4 strains by pulsed field gel electrophoresis (PFGE) and repetitive PCR (rep-PCR) (DiversiLab, bioMérieux, France). All isolates conferred high level [minimum inhibitor concentration (MIC) > 256 mg/L] vancomycin and teicoplanin resistance by E-test method. The isolates were also found resistant to gentamicin, streptomycin, ampicillin, erythromycin, penicillin and were susceptible to tetracycline and linezolid. The vanA gene was detected in all strains by PCR. It was demonstrated that the 4 VRE strains belonged to a single clone as shown by both PFGE and rep-PCR methods. Prompt and accurate detection of VRE and determination of the genotypes is of crucial importance to prevent horizontal transfer of the strains in the hospital. When compared with PFGE, the DiversiLab commercial rep-PCR seems to be a reliable and more rapid method to detect the genetic relationship between strains leading to an outbreak.

[Investigation of oxidative stress and antioxidant defense in patients with hepatitis B virus infection and the effect of interferon-alpha plus lamivudine combination therapy on oxidative stress]. / Hepatit B virus enfeksiyonlu hastalarda oksidatif stres ve antioksidan kapasitenin arastirilmasi ve interferon-alpha-lamivudin kombinasyon tedavisinin oksidatif stres üzerine etkisi.

The aim of our study is to determine the role of oxidative stress on hepatic damage in patients with acute and chronic hepatitis B virus (HBV) infection and the efficacy of antioxidant-enzyme system against oxidative stress. Furthermore, the effect of interferon-alpha (IFN-alpha) plus lamivudine therapy on oxidative stress was also investigated. Nineteen patients with acute hepatitis B virus (AHBV) infection, 17 patients with chronic hepatitis B virus (CHBV) infection, 24 inactive HBsAg carriers and 21 healthy controls were included in the study. In control and patient groups, serum alanine-aminotransferase (ALT) and aspartate aminotransferase (AST) levels, erythrocyte malondialdehyde (MDA) levels, erythrocyte superoxide dismutase (CuZn-SOD) and glutathione peroxidase (GSH-Px) activities were measured. In CHBV group, after IFN-alpha plus lamivudine therapy for 6 months, these parameters were measured again. In all patient groups erythrocyte MDA levels were detected higher than control group (p < 0.05). Activity of CuZn-SOD was found to be the highest in AHBV (p < 0.05), and the lowest before the treatment in CHBV group (p < 0.05) compared with other groups. Activity of GSH-Px was found to be the highest in AHBV compared with inactive HBsAg carriers (p < 0.05) and CHBV group before treatment (p < 0.05). Activity of GSH-Px was found to be the lowest in CHBV group before treatment compared with other groups (p < 0.05). In CHBV group there was a significant decrease of MDA levels after treatment (p < 0.05) while there was a significant increase in activity of CuZn-SOD and GSH-Px compared with pretreatment levels (p < 0.05). A significant positive correlation was determined between MDA values and serum ALT levels, before and after the treatment (p < 0.05). Detection of the increase of MDA levels which is a product of lipid peroxidation in all patient groups, indicates that the oxidative stress is increased in HBV infection. Correlation between the levels of erythrocyte MDA levels and serum ALT levels supports the hypothesis concerning the role of oxidative stress in pathogenesis of HBV infection. Insufficiency of antioxidant capacity in CHBV and inactive HBsAg carrier groups may lead to progression of disease and results in fibrosis. Treatment with IFN-alpha plus lamivudine causes a decrease in products of lipid peroxidation and shows antioxidant activity via increasing the antioxidant enzymes. These data suggest that the addition of antioxidant agents to IFN-alpha and lamivudin combination therapy may be useful in CHBV treatment. Further in-vitro and in-vivo studies are required to enlighten the role of antioxidants on HBV disease progression and treatment.

[Genotypic characteristics of Neisseria meningitidis serogroup W-135 strains isolated as the agent of fatal meningitis in a military hospital]. / Bir askeri hastanede fatal menenjit etkeni olarak izole edilen Neisseria meningitidis serogrup W-135 suslarinin genotipik özellikleri.

The aim of this study was to describe the genetic characterization of a total of 6 Neisseria meningitidis serogroup W-135 strains isolated from patients with meningitis and carriers in a military hospital in 2007-2008. Suspected colonies on modified Thayer-Martin medium plates were screened for oxidase reactivity and Gram stain. If gram-negative diplococci were present, a biochemical profile by the API NH system was used for species confirmation. Pulse field gel electrophoresis typing of Nhel-digested DNA was performed by a previously described method. Multi-locus sequence typing (MLST) was performed using the standard primers as listed on the Neisseria MLST website. Three distinct sequence types (STs) were identified: ST-11, ST-2754, ST-3751. One of the clinical isolates was identified as the same sequence type with Hajj isolate (ST-11) and the isolate with ST-2754 was the same as the first Turkish clinical strain isolated in 2003. These data demonstrated that along with ST-11 which is a known Hajj isolate, the ST-2754 strain causing meningococcal disease in Turkey beginning from the year 2003, should be carefully monitored.

Can imaging modalities be used as follow-up criteria after brucellar sacroiliitis treatment?

INTRODUCTION: This study aimed to identify a follow-up modality that can be used to evaluate therapeutic responses in patients receiving treatment for brucellar sacroillitis and to determine whether antibiotherapy can be stopped. METHODOLOGY: A total of 32 patients with sacroiliac joint involvement demonstrated via magnetic resonance imaging or bone scintigraphy were followed up and treated. Patients received 200 mg/day of doxycycline and 600-900 mg/day of rifampicin for 3-21 months, and 1 g/day of streptomycin for 21 days. RESULTS: The mean age of the 32 patients involved was 21.81±4.09. In total, 10/32 patients did not complete therapy, and the remaining 22 patients received combination antibiotic treatment for a mean of 8.95±4.34 months. Of the 22 patients, 15 underwent MRI, and 7 of them did not consent to MRI. Similarly, 17 patients were followed up by bone scintigraphy, and 5 patients did not have scintigraphy results. In 9/17 patients followed up with bone scintigraphy, sacroiliitis findings were found to reduce after a mean of 7.44±3.71 months, whereas in 12/15 patients on whom MRI was performed,  there were no active sacroiliitis findings for a mean of 6.95±2.83 months. CONCLUSIONS: While active involvement findings in bone scintigraphy were observed for a longer period in scintigraphy images, active sacroiliitis findings disappeared in a relatively shorter period of time with MRI. Therefore, we have demonstrated that high-resolution MRI is a very sensitive technique compared to scintigraphy.

A case of mucosal leishmaniasis: Mimicking intranasal tumor with perforation of septum.

A 79-year-old male suffering from nasal congestion was referred to our hospital. Endoscopic examination revealed a hyperemic mass obstructing the left nasal passage. The lesion's surface was smooth. The findings of imaging studies were consistent with a benign tumor despite the erosion and perforation of the septum. The lesion originated from the middle concha and was attached to it with a thin stalk. It was removed easily by endoscopic resection. Histopathology revealed significant infiltration of mononuclear inflammatory cells, mostly lymphocytes and histiocytes, into the edematous subepithelial connective tissue. High-power magnification showed numerous Leishmania amastigotes in the cytoplasm of the histiocytes. A polymerase chain reaction experiment for Leishmania also confirmed the morphological diagnosis. No relapse was observed in the 12 months after surgery and the patient was doing well.

Freezing of Apheresis Platelet Concentrates in 6% Dimethyl Sulfoxide: The First Preliminary Study in Turkey.

OBJECTIVE: Transfusion of platelet suspensions is an essential part of patient care for certain clinical indications. In this pioneering study in Turkey, we aimed to assess the in vitro hemostatic functions of platelets after cryopreservation. MATERIALS AND METHODS: Seven units of platelet concentrates were obtained by apheresis. Each apheresis platelet concentrate (APC) was divided into 2 equal volumes and frozen with 6% dimethyl sulfoxide (DMSO). The 14 frozen units of APCs were kept at -80 °C for 1 day. APCs were thawed at 37 °C and diluted either with autologous plasma or 0.9% NaCl. The volume and residual numbers of leukocytes and platelets were tested in both before-freezing and post-thawing periods. Aggregation and thrombin generation tests were used to analyze the in vitro hemostatic functions of platelets. Flow-cytometric analysis was used to assess the presence of frozen treated platelets and their viability. RESULTS: The residual number of leukocytes in both dilution groups was <1x106. The mean platelet recovery rate in the plasma-diluted group (88.1±9.5%) was higher than that in the 0.9% NaCl-diluted group (63±10%). These results were compatible with the European Directorate for the Quality of Medicines quality criteria. Expectedly, there was no aggregation response to platelet aggregation test. The mean thrombin generation potential of post-thaw APCs was higher in the plasma-diluted group (2411 nmol/L per minute) when compared to both the 0.9% NaCl-diluted group (1913 nmol/L per minute) and the before-freezing period (1681 nmol/L per minute). The flow-cytometric analysis results for the viability of APCs after cryopreservation were 94.9% and 96.6% in the plasma and 0.9% NaCl groups, respectively. CONCLUSION: Cryopreservation of platelets with 6% DMSO and storage at -80 °C increases their shelf life from 7 days to 2 years. Besides the increase in hemostatic functions of platelets, the cryopreservation process also does not affect their viability rates.

In vitro efficacy of frozen erythrocytes: implementation of new strategic blood stores to alleviate resource shortage (issue revisited).

BACKGROUND/AIM: Currently, the provision of blood products largely depends on walking blood banks and limited amounts of stored blood with short shelf lives. We aimed to compare the efficacy of erythrocyte concentrate (ECs) by pre- and postfreezing in vitro tests. MATERIALS AND METHODS: In our study, 10 ECs were glycerolized, frozen, thawed, and then deglycerolized using the Naval Blood Research Laboratory method. In addition to using the standard tests, ATP and 2,3-DPG levels and the viability of erythrocytes were also determined. RESULTS: The prefreezing mean viability rates of erythrocytes changed from 89.7 ± 13.7% to 98.6 ± 1.8% after thawing and deglycerolization. Prefreezing and day 0 ATP levels (1.64 ± 0.15 µmol/g Hb and 1.81 ± 0.14 µmol/g Hb, respectively) were similar. The 2,3-DPG levels decreased from 18.09 ± 4.78 µmol/g Hb measured before the procedure to 10.41 ± 4.58 µmol/g Hb on day 0. The mean hemolysis rates and supernatant Hb levels changed from 0.21 ± 0.11% to 0.36 ± 0.12% and 1 ± 0.5 g/L to 1.5 ± 0.5 g/L, respectively. CONCLUSION: The test results showed the efficacy of the frozen-thawed ECs to be used in humans for a broad spectrum of clinical indications. As a part of a contingency plan, national frozen blood reserves need to be established.

The role of human leukocyte antigen tissue groups in hepatitis B virus vaccination in Turkey.

BACKGROUND/PURPOSE: Between 5% and 10% of the vaccinated population responds less well to standard vaccination schedules irrespective of hepatitis B virus (HBV) vaccination. This manuscript aims at describing possible correlation of different major histocompatibility complex (MHC) Class-I and MHC Class-II haplotype to anti-HBV humoral responsiveness following HBV vaccination. MATERIALS AND METHODS: The study was conducted on 944 vaccinated hospital staff members and concentrated on the 38 nonresponders as defined by enzyme-linked immunosorbent assay (ELISA) results. In order to define significance of the different haplotypes from the nonresponders, their frequency was compared to the frequency of the same haplotype in 18 randomly selected responders. Human leukocyte antigen (HLA)-A and HLA-B antigens were typed among total mononuclear cells using a standard two-stage microlymphocytotoxicity test. The typing method of HLA Class-II is based on a technique that involves amplification of the second exon of different HLA Class-II genes by PCR. RESULTS: Positive correlations were found between four HLA-DR (HLA-DRB1*04X, DRB1*0401X, DRB1*11/13, and DRB1*0401X0201) haplotypes and nonresponders but there was a negative correlation with one Class-I (HLA-B13). CONCLUSION: This study suggested that certain HLA types are associated with nonresponsiveness to vaccination. The different HLA of ethnic groups should also be kept in mind when evaluating the response to hepatitis vaccination. The different HLA gene frequencies of ethnic groups should be examined in further large-scale population-based studies.

Oropharyngeal tularemia cases admitted to a military hospital in Ankara, Turkey.

INTRODUCTION: This study aimed to review the possible sources of infection of 16 oropharyngeal tularemia hospital cases, and to document their epidemiological and demographical characteristics, laboratory findings, treatment methods, and treatment results. METHODOLOGY: Sixteen cases from a Turkish military hospital between January 2011 and December 2012 were retrospectively evaluated. The age, sex, occupation, place of residence, symptoms, duration of symptoms, laboratory results, treatment and duration, and treatment results were recorded. Tularemia was diagnosed through tularemia-specific tests once the other conditions that may have caused lymphadenopathy were excluded. RESULTS: Twelve of the patients included in this study were males. The average age of the patients was 32.1 ± 17.2 years. Sore throat, fatigue, and fever were the most frequent symptoms. The mean duration of symptoms was 21.6 ± 6.9 days. All the patients had been treated for tonsillopharyngitis in primary healthcare institutions previously. However, despite the treatment, cervical lymphadenopathy had developed in these cases. Patients were given streptomycin, doxycycline, and ciprofloxacin monotherapy or in combination. Ten of the cases fully recovered, while five required surgical lymph node drainage. Spontaneous drainage occurred in the single remaining case. CONCLUSIONS: Turkey is considered to be an endemic country with regards to tularemia. Prompt diagnosis and proper treatment of the disease is imperative in providing cure. Since it can be potentially confused with tuberculous lymphadenitis, differential diagnosis is vital. Patients presenting with a condition of tonsillopharyngitis in endemic areas must be carefully monitored.

Brucellar epididymo-orchitis: a retrospective multicenter study of 28 cases and review of the literature.

OBJECTIVE: To review retrospectively the clinical symptoms, laboratory findings and treatment outcomes of patients with Brucellar epididymo-orchitis. MATERIAL AND METHOD: Retrospective data of 28 patients with Brucellar epididymo-orchitis who admitted to four medical centers between 2005 and 2013 were retrospectively reviewed. Positive blood culture, positive Rose Bengal test results or high agglutination titres of ≥ 1/160 with the positive clinical and ultrasonographic findings of orchitis were accepted as the main criteria for Brucellar epididymo-orchitis. RESULTS: The mean patient age was 31 ± 16.9 years. Testicular involvement was on the left side in 16 patients and on the right side in 11 patients, one had bilateral disease. Testicular pain and swelling were the most common symptoms and elevation of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leucocytosis were the most common laboratory findings. Initial treatment was orchidectomy in six patients due to malignancy suspicion. All but three patients were successfully treated with antibiotic combinations of rifampicin, doxycycline and streptomycin. Two of three treatment resistant patients underwent orchidectomy. CONCLUSION: Brucellosis is a common cause of epididymo-orchitis in endemic regions. Early diagnosis and treatment is crucial in the management and thus it must be kept in mind in endemic and non-endemic regions.

Comparison of probe disinfection procedures in routine ultrasonography: hot water versus antiseptic wiping.

OBJECTIVE: It is commonly known that ultrasonography (US) transducers function as both a reservoir and means of transfer for hospital infections. The current study aimed to compare the antimicrobial effectiveness of using >80 °C water versus antiseptic wipes to disinfect US transducers. METHODS: Subsequent to abdominal inspections in three groups of 20 patients, a swab culture was taken from the transducer in each case. Neither a mechanical nor chemical disinfection was applied to the transducer in the first group. As for the second group, the transducer was placed in >80 °C hot water for five minutes. In the third group, the transducer was wiped clean using antiseptic wipes. RESULTS: Of the 60 swab samples collected, 40 did not produce any growth. The number of samples exhibiting growth in the first group involved 18 cases of coagulase-negative staphylococcus (CNS), as well as 15 cases of Listeria spp., one case of Corynebacterium spp. and one case of Bacillus spp., while only one case of CNS was observed in the second and third groups, respectively. The culture growth and colony forming units rate were significantly higher in the samples obtained from the first group than in those obtained from the other groups (p<0.01). As for the second and third groups, no significant differences were found in terms of the amount of colonization and growth (p=1.00). CONCLUSION: Being a practical and a simple method for particular use in developing and underdeveloped countries, where it is hard to access relatively costly transducer disinfection materials, such as antiseptic wipes, hot water disinfection may play an active role in fighting hospital infections.

Adult onset Still's disease as a paraneoplastic syndrome--a case report and review of the literature.

Adult onset Still's disease (AOSD) is a systemic inflammatory disease with unknown etiology and characterized by evanescent salmon pink rash, sore throat, liver dysfunction, lymphadenopathy, hepatosplenomegaly, arthritis, and leukocytosis. It is a diagnosis of exclusion; however, there are case reports in the literature about patients with malignancies and AOSD-like signs and symptoms. Here we report a patient with AOSD seems to be associated with sarcomatoid renal cell carcinoma. This phenomenon is not distinguishable from primary AOSD either in presentation or in treatment; except for the main purpose of the management should be targeted to the underlying malignancy.
