Objective: Treponema pallidum and HIV are transmitted frequently through sexual contact, these agents with epidemiological similarities co-infect the same host. The current number of HIV-infected cases in Turkey is increasing. For this reason, we aimed to reveal the characteristics of syphilis in HIV/AIDS cases. Methods: A retrospective longitudinal cohort study was performed, patients were followed up at 24 clinics in 16 cities from all seven regions of Turkey between January 2010 to April 2018. We examined the socio-demographic characteristics, laboratory parameters and neurosyphilis association in HIV/AIDS-syphilis co-infected cases. Results: Among 3,641 patients with HIV-1 infection, 291 (8%) patients were diagnosed with syphilis co-infection. Most patients were older than 25 years (92%), 96% were males, 74% were working, 23% unemployed, and 3% were students. The three highest prevalence of syphilis were in Black Sea (10.3%), Mediterranean (8.4%) and Marmara Regions (7.4%). As for sexual orientation, 46% were heterosexuals, 42% men who have sex with men (MSM), and no data available for 12%. Patients with the number of CD4+

- Abstract
No data on whether brucellar meningitis or meningoencephalitis can be treated with oral antibiotics or whether an intravenous extended-spectrum cephalosporin, namely, ceftriaxone, which does not accumulate in phagocytes, should be added to the regimen exist in the literature. The aim of a study conducted in Istanbul, Turkey, was to compare the efficacy and tolerability of ceftriaxone-based antibiotic treatment regimens with those of an oral treatment protocol in patients with these conditions. This retrospective study enrolled 215 adult patients in 28 health care institutions from four different countries. The first protocol (P1) comprised ceftriaxone, rifampin, and doxycycline. The second protocol (P2) consisted of trimethoprim-sulfamethoxazole, rifampin, and doxycycline. In the third protocol (P3), the patients started with P1 and transferred to P2 when ceftriaxone was stopped. The treatment period was shorter with the regimens which included ceftriaxone (4.40 +/- 2.47 months in P1, 6.52 +/- 4.15 months in P2, and 5.18 +/- 2.27 months in P3) (P = 0.002). In seven patients, therapy was modified due to antibiotic side effects. When these cases were excluded, therapeutic failure did not differ significantly between ceftriaxone-based regimens (n = 5/166, 3.0%) and the oral therapy (n = 4/42, 9.5%) (P = 0.084). The efficacy of the ceftriaxone-based regimens was found to be better (n = 6/166 [3.6%] versus n = 6/42 [14.3%]; P = 0.017) when a composite negative outcome (CNO; relapse plus therapeutic failure) was considered. Accordingly, CNO was greatest in P2 (14.3%, n = 6/42) compared to P1 (2.6%, n = 3/ 117) and P3 (6.1%, n = 3/ 49) (P = 0.020). Seemingly, ceftriaxone-based regimens are more successful and require shorter therapy than the oral treatment protocol.

- Abstract
We investigated the role played by cytokines in the mortality of patients with Crimean-Congo hemorrhagic fever (CCHF). Serum levels of several cytokines were measured in 3 patients with fatal CCHF and in 27 patients with nonfatal CCHF. Levels of interleukin (IL)-6 (P=.001) and tumor necrosis factor (TNF)- alpha (P=.004) were significantly higher in patients with fatal CCHF than in patients with nonfatal CCHF, whereas levels of IL-10 were not significantly different between the 2 groups (P=.937). Disseminated intravascular coagulation (DIC) scores were also higher in the patients with fatal CCHF (P=.023). Levels of IL-6 and TNF- alpha were positively correlated with DIC scores, whereas levels of IL-10 were negatively correlated with DIC scores. In conclusion, these findings demonstrate that proinflammatory cytokines play a major role in the mortality of patients with CCHF.

- Abstract
Objective: The aim of this study was to analyze the temporal trends of HIV epidemiology in Turkey from 2011 to 2016., Methods: Thirty-four teams from 28 centers at 17 different cities participated in this retrospective study. Participating centers were asked to complete a structured form containing questions about epidemiologic, demographic and clinical characteristics of patients presented with new HIV diagnosis between 2011 and 2016. Demographic data from all centers (complete or partial) were included in the analyses. For the cascade of care analysis, 15 centers that provided full data from 2011 to 2016 were included. Overall and annual distributions of the data were calculated as percentages and the Chi square test was used to determine temporal changes., Results: A total of 2,953 patients between 2011 and 2016 were included. Overall male to female ratio was 5:1 with a significant increase in the number of male cases from 2011 to 2016 (p<0.001). The highest prevalence was among those aged 25-34 years followed by the 35-44 age bracket. The most common reason for HIV testing was illness (35%). While the frequency of sex among men who have sex with men increased from 16% to 30.6% (p<0.001) over the study period, heterosexual intercourse (53%) was found to be the most common transmission route. Overall, 29% of the cases presented with a CD4 count of >500 cells/mm3 while 46.7% presented with a CD4 T cell count of <350 cells/mm3. Among newly diagnosed cases, 79% were retained in care, and all such cases initiated ART with 73% achieving viral suppression after six months of antiretroviral therapy., Conclusion: The epidemiologic profile of HIV infected individuals is changing rapidly in Turkey with an increasing trend in the number of newly diagnosed people disclosing themselves as MSM. New diagnoses were mostly at a young age. The late diagnosis was found to be a challenging issue. Despite the unavailability of data for the first 90, Turkey is close to the last two steps of 90-90-90 targets., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

- Abstract
Early diagnosis and treatment of acute brucellosis cases were targeted by screening the household members of the index cases. We also aimed to describe the causal relations of brucellosis in an endemic region. A cross-sectional study was performed among household members (29 index cases, 113 household members). Brucellosis was diagnosed on the basis of clinical findings, serum agglutinin titer of ≥1/160 in standard tube agglutination test (STA), or a positive blood culture. Index cases were defined as patients who had been admitted to the clinic on suspicion of brucellosis and then confirmed as brucellosis cases. The people who lived in the same house as the index cases were defined as household members. The risk factors for seropositivity were studied by multivariate analysis. Independent variables of gender, consuming fresh cheese, blood groups, dealing with husbandry, and contact with the placenta of infected animals were included to the model. Backward and forward selections were performed. Nineteen out of 113 (17%) screened individuals had agglutination titers ≥1/160. The mean ages of index cases and household members were 43 years (standard deviation [SD] 18) and 29 years (SD 19), respectively. In multivariate analysis, consuming fresh cheese (odds ratio [OR]=3.1, confidence interval [CI] 1.07-9.68, p=0.049), blood group A (OR=2.6, CI 1.18-5.96, p=0.018), contact with the placenta of the infected animals (OR=3.7, CI 1.42-9.68, p=0.007), and age >30 years (OR=2.8, CI 1.25-6.51, p=0.13) were found to be associated with brucellosis. In univariate analysis, the individuals with blood group B were protected from brucella infection (p=0.013). In conclusion, screening of the people in brucellosis-endemic areas should be considered for early diagnosis and treatment. To our knowledge, blood groups were studied for the first time by this study. Higher prevalence of brucellosis among the individuals with blood group A and less prevalence among the individuals with blood group B should be considered for further studies on pathogenesis.

- Abstract
Introduction: Routes of transmission and reasons for HIV testing are important epidemiologic data to analyze the epidemic and to tailor the response to AIDS. The aim of this study was to analyze reasons for testing and transmission ways of HIV among recently diagnosed HIV patients registered in the multicenter HIV-TR cohort in Turkey., Methods: Transmission ways and reasons for testing of all patients diagnosed in 2011 and 2012 were recorded on a web-based data collection system and were analyzed retrospectively., Results: The study included 693 patients (561 male, 132 female) from 24 sites. Reason for HIV testing was available in 640 patients (92%). The most common reason for HIV testing was diagnostic workout for other conditions or illness followed by patient-initiated testing. The reasons for testing were listed in Table 1. The most common routes of HIV transmission were heterosexual intercourse (62.7%) and sex among men who have sex with men (MSM) (22.6%). At the time of HIV diagnosis, the mean CD4 lymphocyte cell count was 355/mm(3) (3-1433/mm(3)). Primary HIV infection was determined in 42/693 (6%) patients and 9/693 (% 1, 2) cases were considered "probable primary HIV infection." The majority of the cases presented to a clinic for follow-up right after the diagnosis. On the other hand 32/616 (5.2%) patients delayed their presentation for more than 3 months. The longest delay was 11 months., Conclusions: The results of the database suggest that targeted testing is lacking in the country. The shift toward homosexual transmission during the last 2 years emphasizes the need for targeted interventions. Patients present relatively late and HIV infection could only be diagnosed when immunosuppression related findings appeared. Patient-initiated testing,an indicator of awareness, was very low suggesting a need to scale-up awareness raising interventions.

- Abstract
Crimean-Congo hemorrhagic fever (CCHF) is a fatal viral infection that involves multiple organs, and endothelium. We described abdominal sonographic findings of the patients infected with the Crimean-Congo hemorrhagic fever virus (CCHFV) in relation to the severity of the disease. This is a prospective study performed among hospitalized patients infected with CCHF between 2005 and 2011. A total of 210 hospitalized patients with confirmed CCHF infection were included in the study. The mean age was 47 and 49.5% of the patients were female. Patients were classified as mild, moderate, or severe disease according to their clinical and laboratory findings. The relationship between the clinical severity of CCHF and the abdominal sonographic findings was analyzed. Sonographic findings of abdomen included gallbladder wall thickening (GBWT) in 44 (21%), splenomegaly in 39 (19%), hepatomegaly in 52 (25%), decrease in echo of liver parenchyma in nine (4%), increase in echo liver parenchyma in 13 (6%), intra-abdominal fluid collection/ascites in 23 (11%), and enlarged periportal lymph nodes in seven (3%) cases. GBWT was detected in 3% of mild patients, 23% of moderate patients, and 61% of severe patients (p<0.001). In multivariate analysis to predict the severity, GBWT (odds ratio [OR] 5.4, confidence interval [CI] 1.76-16.49, p=0.003) and intra-abdominal fluid collection/ascites (OR 3.5, CI 1.07-12.61, p=0.049) were found to be significantly associated with disease severity. In conclusion, ultrasonography is a reliable, useful, and noninvasive diagnostic tool for evaluation of the abdominal findings of the patients with CCHFV infection. GBWT and intra-abdominal fluid collection/ascites were found to be predictors of severity.

- Abstract
Introduction: Tularemia is a zoonotic disease caused by Francisella tularensis. The oculoglandular form is one of the rarest forms. In this study, evaluated tularemia patients, focusing on the ocular form and the efficacy of early antibiotic therapy., Methodology: During a tularemia outbreak, the epidemiological and clinical findings, laboratory assays, and drugs used for the treatment of 48 patients were recorded prospectively. The diagnosis of tularemia was confirmed with microagglutination test (MAT) as well as clinical findings., Results: The mean age of the subject was 48.6 years; 23 (47.9%) of them were female. Thirty-six (81.25%) patients had clinical presentation compatible with oropharyngeal tularemia, seven (14.58%) with oculoglandular tularemia, and two (4.1%) with ulceroglandular tularemia. The most common symptoms were fever (91.6%) and sore throat (81.2%), and the most common findings were lymphadenopathy (91.6%) and tonsillopharyngitis (81.2%). In the oculoglandular form, fever, lymphadenopathy, periorbital edema, conjunctival injection, and chemosis were found. The most distinctive ophthalmic feature was follicular conjunctivitis and conjunctival epithelial defects. Forty-five cases had positive serological results with MAT. All the patients were treated with antibiotics considered effective against F. tularensis, and topical antimicrobial treatment was given to the patients with oculoglandular tularemia. Twenty-six (54.16%) patients, who were admitted within three weeks of the onset of symptoms, recovered without sequel., Conclusions: During tularemia outbreaks, ocular involvement should be considered carefully. The early administration of appropriate treatment will be more effective in resolving the infection and preventing complications. Along with systemic antibiotic therapy, topical treatment will help recovery.

- Abstract
Background: Patients infected with Crimean-Congo hemorrhagic fever (CCHF) virus present with a wide clinical spectrum. In observational studies, the effects of therapeutic agents are confounded by severity. We describe use of a clinical severity scoring index (SSI) for CCHF patients and assess the effect of ribavirin and corticosteroid therapy on the case-fatality rate, stratified by SSI., Methods: The study group included hospitalized patients who received a diagnosis of CCHF at the Infectious Diseases and Clinical Microbiology Clinic of Ankara Numune Education and Research Hospital between 2004 and 2011. The SSI included platelet count, bleeding, fibrinogen level, activated partial thromboplastin time, and somnolence. The effects of ribavirin and corticosteroid on the case-fatality rate were studied by univariate and multivariate analysis, stratified by SSI., Results: Two hundred eighty-one confirmed cases of CCHF were included in the study. Of 281 patients, 23 (8%) died. The mean age (±SD) of the patients was 47 ± 16 years. Forty-nine percent were female. The mean duration of stay at our clinic after onset of symptoms was 4.4 days, with a range of 1-14 days. In multivariate analysis of factors for the prediction of death, the SSI (odds ratio [OR], 3.27; 95% confidence interval [CI], 2.09-5.13) and ribavirin use (OR, 0.04; 95% CI, .004-.48) were found to be statistically significant factors., Conclusion: The SSI is an accurate predictor of death and will therefore be a useful tool for case management and for drug-assessment studies. After stratification of cases by SSI, ribavirin was found to be effective in reducing the case-fatality rate, especially among moderately ill patients, whereas steroids were found to be beneficial particularly among patients with severe disease.

- Abstract
Background: We describe the neurological involvement in brucellosis and revisited diagnostic criteria for neurobrucellosis., Methods: Patients with laboratory-confirmed brucellosis who were consequently hospitalized were observed prospectively in a brucellosis-endemic region. The neurobrucellosis was diagnosed by any one of the following criteria: (1) symptoms and signs consistent with neurobrucellosis; (2) isolation of Brucella species from cerebrospinal fluid (CSF) and/or presence of anti-Brucella antibodies in CSF; (3) the presence of lymphocytosis, increased protein, and decreased glucose levels in CSF; or (4) diagnostic findings in cranial magnetic resonance imaging or CT., Results: Lumbar puncture was performed in 128 laboratory-confirmed brucellosis cases who had neurological symptoms and signs, and 48 (37.5%) were diagnosed as neurobrucellosis. The sensitivity of tube agglutination (TA) in CSF was 0.94, specificity 0.96, positive predictive value 0.94, and negative predictive value 0.96. Brucella bacteria were isolated from CSF in 7 of 48 patients (15%). The mean age of 48 neurobrucellosis patients was 42 years (SD, 19 years), and 16 (33%) were female. The most common neurological findings were agitation (25%), behavioral disorders (25%), muscle weakness (23%), disorientation (21%), and neck rigidity (17%). Cranial nerves were involved in 9 of 48 patients (19%). One patient was left with a sequela of peripheral facial paralysis and 2 patients with sensorineural hearing loss., Conclusions: Patients with severe and persistent headache and other neurologic symptoms and signs should be considered for neurobrucellosis in endemic regions and to possibly receive longer therapy than 6 weeks. Brucella TA with Coombs test in CSF is sensitive and specific by using a cutoff of ≥1:8.

- Abstract
Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne infection which has been increasing in Turkey and European countries since the year 2000. The disease is particularly endemic in the Middle East and in some African countries. It is also seen in European countries as a travel infection. Patients with confirmed diagnosis are usually hospitalized for monitoring, while patients with good overall condition may be monitored on an outpatient basis. Hospitals that manage CCHF should have easy access to a blood bank, and tertiary care hospitals must have a well-equipped intensive care unit. Strict blood and body fluid control precautions should be started on admission to limit CCHF exposure. The follow-up period for each patient is determined based on individual clinical status and laboratory values. Since there is no specific antiviral treatment for CCHF, supportive treatment is essential. This review highlights some of the major features of case monitoring and supportive treatment in CCHF.

- Abstract
No data on whether brucellar meningitis or meningoencephalitis can be treated with oral antibiotics or whether an intravenous extended-spectrum cephalosporin, namely, ceftriaxone, which does not accumulate in phagocytes, should be added to the regimen exist in the literature. The aim of a study conducted in Istanbul, Turkey, was to compare the efficacy and tolerability of ceftriaxone-based antibiotic treatment regimens with those of an oral treatment protocol in patients with these conditions. This retrospective study enrolled 215 adult patients in 28 health care institutions from four different countries. The first protocol (P1) comprised ceftriaxone, rifampin, and doxycycline. The second protocol (P2) consisted of trimethoprim-sulfamethoxazole, rifampin, and doxycycline. In the third protocol (P3), the patients started with P1 and transferred to P2 when ceftriaxone was stopped. The treatment period was shorter with the regimens which included ceftriaxone (4.40 ± 2.47 months in P1, 6.52 ± 4.15 months in P2, and 5.18 ± 2.27 months in P3) (P = 0.002). In seven patients, therapy was modified due to antibiotic side effects. When these cases were excluded, therapeutic failure did not differ significantly between ceftriaxone-based regimens (n = 5/166, 3.0%) and the oral therapy (n = 4/42, 9.5%) (P = 0.084). The efficacy of the ceftriaxone-based regimens was found to be better (n = 6/166 [3.6%] versus n = 6/42 [14.3%]; P = 0.017) when a composite negative outcome (CNO; relapse plus therapeutic failure) was considered. Accordingly, CNO was greatest in P2 (14.3%, n = 6/42) compared to P1 (2.6%, n = 3/117) and P3 (6.1%, n = 3/49) (P = 0.020). Seemingly, ceftriaxone-based regimens are more successful and require shorter therapy than the oral treatment protocol.

- Abstract
Background: Incidence of anthrax is diminishing in developed countries; however, it remains a public health problem in developing countries, especially those whose main source of income is farming., Methodology: Charts of patients hospitalized between 1992 and 2008 in the Infectious Diseases and Clinical Microbiology Department of Ankara Numune Education and Research Hospital were reviewed., Results: Fifty-eight cases with cutaneous anthrax were reviewed. The mean age was 49.8, and 36.2% were female. The most common professions were farmers (62%), butchers (19%), and housewives (15%). The mean incubation period was eight days. Most cases (62%) were exposed to bacteria when butchering sick animals. Eighteen patients used an antibiotic before admission to hospital (31%). The predominantly affected sites were hands (39%) and fingers (29%), followed by forearms (12%), eyelids (7%) and necks (3%). All cases initially had painless ulcers with vesicles; dissemination of the lesion was seen in 27.5% of patients. Gram stain was positive in 11 cases; culture was positive in 7 cases for Bacillus anthracis. All patients except one were discharged and treated with penicillin and/or ciprofloxacin or imipenem. One patient with a disseminated lesion on the neck died even though a steroid was used with the antibiotic., Conclusions: Cutaneous anthrax should be considered as a possible diagnosis in cases with a painless ulcer with vesicles, edema, and a history of exposure to animals or animal products. Despite previous antibiotic use, taking smears and cultures should be encouraged. Treatment with penicillin G or penicillin procain alone is effective for cases with cutaneous anthrax without severe edema and superinfection.

- Abstract
Objective: The aim of this study was to evaluate the efficacy of oral ribavirin treatment in patients with Crimean-Congo haemorrhagic fever (CCHF)., Methods: In 2004, all patients diagnosed with CCHF were treated with oral ribavirin, however in 2003 none of the CCHF patients had been given treatment due to lack of confirmatory diagnostic information at that time in Turkey. In this study, patients treated with ribavirin in 2004 (n=126) were compared with ribavirin-untreated CCHF patients (n=92) in 2003. Patients only with a definitive diagnosis of CCHF (clinical symptoms plus the presence of specific IgM antibodies against CCHF virus and presence of viral antigen) were included in this study., Results: There was no difference in the case-fatality rate between treated and untreated patients (7.1% vs. 11.9%; P>0.05). A Cox Proportional Hazards regression analysis revealed that altered sensorium and prolonged international normalized ratio were independent predictors of mortality., Conclusion: Our results showed that oral ribavirin treatment did not improve the survival rate in CCHF patients. Ribavirin and supportive care are the only available choices for treatment of CCHF patients, but to ascertain the efficacy of ribavirin, more laboratory and observational studies are necessary and ultimately, to elucidate these conflicting results and evaluate the efficacy undoubtedly, a multicenter randomised controlled trial will be needed.

- Abstract
The authors describe the epidemiologic and clinical characteristics of 97 human immunodeficiency virus (HIV)-infected patients, who were followed between 1993 and 2006. Seventy-two percent of the patients were male, and median age at diagnosis was 36 years (range, 13-71 years). The mean years of survival was 3, and maximum length of life after diagnosis was 9 years. The most common professions were truck drivers, workers, and housewives. Forty-six percent of the males had a history of working abroad. Heterosexual intercourse was the most common (84%) route of transmission. Seventy-four percent of the women acquired infection from their husbands. In Turkey, less educated or uneducated and poor men are the primary target of the HIV infection usually by sexual contact with foreign women. Considering the low education status of the patients, appropriate education programs should be developed to prevent the dissemination of HIV infection. Because a significant number of patients were diagnosed at very late stages, the physicians and other health care workers should be educated on the clinical pictures of HIV/AIDS., (© 2008 Sage Publications)

- Abstract
We aimed to detect antibodies against Crimean-Congo hemorrhagic fever virus (CCHFV) in healthcare workers (HCWs) in an endemic region. The study was conducted in a tertiary care hospital that had cared for CCHFV infected patients in the period 2002-2003. The sera from the HCWs were collected one month after the last admitted hospital case (October 2003), and sent to the Pasteur Institute, Lyon, France to be studied for CCHF IgM and IgG by ELISA. The total number of HCWs included in the study was 75; the median age was 30, 68% of the subjects were female, and 83% of the HCWs were at risk of exposure to the body fluids of patients. Only one HCW from the group without risk of exposure was CCHF IgG positive. The adherence rate to universal precautions was high. In conclusion, a lack of CCHFV transmission from patients to HCWs was observed. This result could be related to the high rate of compliance to the universal precautions, which are sufficient to protect against CCHFV infection.

- Abstract
Background: To investigate the immune status of health care workers (HCWs) against measles, rubella, mumps, and varicella zoster (MMRV) in Turkey and to define an appropriate vaccination program among HCWs., Methods: Voluntary HCWs from a children's hospital and a general hospital were included in the study between March and May 2005. The specific IgG antibodies against MMRV viruses were screened by ELISA., Results: Three hundred sixty-three HCWs participated in the study; 186 (51%) were physicians, 118 (33%) were nurses, 36 (10%) were housekeeping staff, and 23 (6%) were medical technicians. The proportion of HCWs who had antibodies against measles was 98.6%; rubella, 98.3%; mumps, 92.2%; and varicella, 98%. No association was found between the susceptibility to at least 1 of MMRV virus infections and gender, age, duration of work, profession, and department of work in analysis either among the whole study group, or each hospital. The positive predictive value for the history of varicella was 100%, whereas it was 92% for MMR. The cost of vaccination for varicella was significantly expensive without screening before vaccination. However, there was not much difference for MMR infections., Conclusion: A policy based on obtaining the history of varicella infection from the staff and then screening the ones with negative history and vaccination of only seronegative HCWs was found to be appropriate.

- Abstract
A Crimean-Congo haemorrhagic fever (CCHF) outbreak emerged from 2001 to 2003 in the Middle Anatolia region of Turkey. This study describes the clinical characteristics and outcome features of CCHF patients admitted to four tertiary care hospitals in Turkey. Definitive diagnosis was based on the detection of CCHF virus-specific IgM by ELISA or of genomic segments of the CCHF virus by RT-PCR. Related data were collected by a retrospective chart review. Hospital costs were extracted from the final discharge bills. Univariate and multivariate analyses were conducted to determine the independent predictors of mortality. CCHF virus-specific antibodies or genomic segments were detected in the sera of 99 cases. Seven cases that were treated with ribavirin were excluded from the study. Cases were mostly farmers (83 cases, 90 %), and 60 % had a tick-bite history before the onset of fever. Impaired consciousness and splenomegaly were independent predictors of a fatal outcome.

- Abstract
In this report, a 27 years old male patient diagnosed to have skin and bone tuberculosis (TB) has been presented. The patient admitted to the hospital with the complaints of fever, weight loss and night sweats. Patient's history revealed that following a trauma a skin lesion in the right ankle was developed and this was followed by the development of many lesions in different parts of the body. The lesions persisted despite the use of various antibiotics since a year. It has been recorded that his father has already been receiving anti-tuberculosis treatment. Osteomyelitis was detected in the distal part of right tibia by computerized tomography, and Mycobacterium tuberculosis was isolated from the specimens of skin lesion. The patient was immunocompetent, and there was no pulmonary involvement. Isoniazid (INAH), rifampin (RIF), ethambutol and morphozinamid therapy has been started and completed to 12 months with INAH and RIF. In the post-treatment follow-up of patient for one year, no relapse was detected. As a result, tuberculosis should be considered in patients with persistent skin lesions especially in endemic countries.

- Abstract
Objective: To determine risk factors for tuberculin skin test (TST) positivity among healthcare workers (HCWs)., Design: Two-step TST was performed in 2002., Setting: Tertiary-care hospital in Ankara, Turkey., Participants: A sample of 491 hospital HCWs were included. Information related to demographics, profession, work duration, department, and individual and family history of tuberculosis (TB) was obtained by a structured questionnaire., Results: Four hundred eight (83%) had two-step TST positivity. On multivariate analysis, male physicians (relative risk [RR], 1.5; 95% confidence interval [CI95], 1.23-1.69; P = .001), nurses (RR, 1.5; CI95, 1.29-1.66; P = .005), radiology technicians (RR, 1.7; CI95, 1.35-1.73; P = .002), laboratory technicians (RR, 1.6; CI95, 1.3-1.74; P = .007), and male housekeepers (RR, 1.6; (HCWs). CI95, 1.38-1.7; P < .001) had a higher risk than did female physicians. Among laboratory technicians, radiology technicians had the highest TST positivity (85%). HCWs working for less than 1 year (RR, 0.8; CI95, 0.72-0.98; P = .027) had a lower risk of infection. The HCWs having bacille Calmette-Guerin vaccination (RR, 1.12; CI95, 1.08-1.45) had higher TST positivity., Conclusion: Male physicians, nurses, and laboratory technicians had increased risk of Mycobacterium tuberculosis infection in this setting, but community exposure likely accounted for most infections.
