Prevalence of sick building syndrome in hospital staff and its relationship with indoor environmental quality.

The aim of this study was to determine the prevalence of sick building syndrome (SBS), and its relationship with indoor environmental quality in hospital settings. This cross-sectional study was carried out on 300 hospital staff in Sivas. MM 040 NA Hospital questionnaire was applied. In the hospital indoor environments, air quality (carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), methane (CH4), hydrogen sulfide (H2S), nitrogen oxides (NOx)), lighting, noise, respirable dust and thermal comfort measurements were made. The prevalence of SBS was determined as 64.7-74.1% in the hospitals. It was found that the risk of SBS was 4.31 times higher for those who complained about variable room temperature and 3.11 times higher for those who complained about noise, and decreased 1.01 times with the increase in lighting level. In order to minimize the risk of SBS, it is thought that all healthcare administrators should be informed about SBS.

Health-related Quality of Life and Associated Factors Among Undergraduate University Students.

OBJECTIVES: The aims of this study were to explore factors associated with health-related quality of life (HRQOL) among students of Cumhuriyet University, Turkey. METHODS: This cross-sectional study involved 1751 undergraduate students. HRQOL was measured using the Turkish version of 36-Item Short Form Health Survey questionnaire. We looked at the effect of sociodemographic characteristics (e.g., gender, age, drinking, and smoking) on the individual HRQOL domains. RESULTS: Place of residency (odds ratio (OR) = 3.947 for role emotion dimension), smoking status (OR = -2.756 for role physical dimension), received amount of pocket money (OR = 2.463 for mental health dimension), and body mass index (OR = 1.463 for mental health dimension) were the factors significantly associated with the HRQOL. CONCLUSIONS: Young students' HRQOL is affected by socioeconomic, demographic, and behavioral factors. To improve student's HRQOL, any health-promoting strategies should focus on modifiable risk factors and socioeconomic supports for students.

Cytotoxic and antibacterial activity of the mixture of olive oil and lime cream in vitro conditions.

The mixture of olive oil and lime cream has been traditionally used to treat external burns in the region of Hatay/Antakya and middle Anatolia. Olive oil and lime cream have been employed by many physicians to treat many ailments in the past. A limited number of studies have shown the antibacterial effect of olive oil and that it does not have any toxic effect on the skin. But we did not find any reported studies on the mixture of olive oil and lime cream. The aim of this paper is to investigate the cytotoxic and antibacterial activity of olive oil and lime cream individually or/and in combination in vitro conditions, by using disk-diffusion method and in cell culture. The main purpose in using this mixture is usually to clear burns without a trace. Agar overlay, MTT (Cytotoxicity assay) and antibacterial susceptibility tests were used to investigate the cytotoxic and antibacterial activity of olive oil and lime cream. We found that lime cream has an antibacterial activity but also cytotoxic on the fibroblasts. On the other hand olive oil has limited or no antibacterial effect and it has little or no cytotoxic on the fibroblasts. When we combined lime cream and olive oil, olive oil reduced its cytotoxic impact. These results suggest that mixture of olive oil and lime cream is not cytotoxic and has antimicrobial activity.

Does hydatid disease have protective effects against lung cancer?

We hypothesized that solid tumors rarely occur in patients with hydatid disease. We obtained the serum of 14 patients diagnosed with hydatid disease, the serum of 10 patients who did not have a history of hydatid disease, and the hydatid cyst fluid from six patients. These sera and fluid samples were added at different concentrations to NCI-H209/An1 human lung small cell carcinoma cells and L929 mouse fibroblasts as a control group. Sera of patients with hydatid diseases had cytotoxic effects on NCI-H209/An1 cells, but they did not have cytotoxic effects on fibroblast cells. Sera from healthy subjects did not have a cytotoxic effect on the tumor cell line or control fibroblasts. Cyst fluid, also, did not have toxic effects on the NCI-H209/An1 cell line, but was toxic to fibroblasts up to a 1:32 dilution. Sera from patients with hydatid disease had cytotoxic effects on human small cell lung cancer cells in vitro.

The cytopathic effects of Trichomonas vaginalis on fibroblast cell culture alone and with C. albicans and E. coli.

OBJECTIVE: In this study, the cytopathic effects of Trichomonas vaginalis were investigated in L929 mouse fibroblast cell cultures (FCC) under different conditions: only parasite, or coexistence with Candida albicans and Escherichia coli. METHODS: The parasite was isolated from a symptomatic patient and cultured in Cysteine-Peptone-Liver infusion Maltose medium (CPLM). C. albicans strain 10235 and E. coli strain 25922 were used in the experiments. Five groups were created and inoculated on FCC. The groups were as follows; only T. vaginalis, C. albicans, E. coli, T. vaginalis+C. albicans and T. vaginalis+E. coli. The plates were incubated for 24 hours and cell viability was examined under an inverted microscope. Each experiment was repeated 11 times. RESULTS: The fibroblast death rate was 19.1%, 21%, 40.9%, 96.5% and 89.6% in the five groups, respectively. CONCLUSION: All fibroblasts were alive in the control group. T. vaginalis showed almost 100% cytopathic effects on FCC with C. albicans and parasites were very motile in this coexistence.

Prevalence of known mutations in the MEFV gene in a population screening with high rate of carriers.

The Familial Mediterranean Fever (FMF) shows an autosomal recessive pattern of inheritance and affects certain ethnic groups. Disease is caused by mutations in MEFV gene and more than 180 mutations have been defined in affected individuals. Current study aimed to determine the frequency-type of the mutations for MEFV gene in Sivas-middle Anatolian city. The cohort was composed of 3340 patients. MEFV gene mutations were studied by multiplex PCR based reverse hybridization stripAssay method. Patients' clinical features were; family history: 68%, erysipelas-like erythema: 17.6%, fever: 89.9%, abdominal pain: 84.2%, peritonitis: 90.2%, arthritis: 33%, pleuritis: 14.2%, parental consanguinity: 21.2%. Current results revealed that M694V is the most frequent mutation (43.12%), followed by E148Q (20.18), M680I(G/C) (15.00%) and V726A (11.32%). The study population has a high rate of carriers and the E148Q mutation frequency was found to be highest when compared to the other regions of Turkey and other Mediterranean groups.

Prevalence of refraction errors and color blindness in heavy vehicle drivers.

AIM: To investigate the frequency of eye disorders in heavy vehicle drivers. METHODS: A cross-sectional type study was conducted between November 2004 and September 2006 in 200 driver and 200 non-driver persons. A complete ophthalmologic examination was performed, including visual acuity, and dilated examination of the posterior segment. We used the auto refractometer for determining refractive errors. RESULTS: According to eye examination results, the prevalence of the refractive error was 21.5% and 31.3% in study and control groups respectively (P<0.05). The most common type of refraction error in the study group was myopic astigmatism (8.3%) while in the control group simple myopia (12.8%). Prevalence of dyschromatopsia in the rivers, control group and total group was 2.2%, 2.8% and 2.6% respectively. CONCLUSION: A considerably high number of drivers are in lack of optimal visual acuity. Refraction errors in drivers may impair the traffic security.

Prevalence of hypertension among high school students in a middle Anatolian province of Turkey.

Hypertension may lead to irreversible damages in vital organs, such as heart, brain, and kidney, and may cause death in children if treatments are not given despite early diagnosis. This cross-sectional epidemiological study was conducted during 1 January-31 March 2004 to investigate the prevalence of hypertension among high school students. The study cohort included 1,041 students of six high schools, who were selected from among 14,789 students of 26 high schools in Sivas province of Turkey, using the cluster-sampling method. A questionnaire was used for collecting information from students on age, gender, smoking, and whether they or their families have any diseases. Blood pressure, height, and weight of the participitants were determined by the research group. Students whose repeated systolic or diastolic blood pressures were higher than the 95th percentile were considered to be hypertensive patients. Hypertension was prevalent among 4.4% (n=45) of the students. There was a significant correlation between prevalence of hypertension and body mass index. No significant correlation was found between prevalence of hypertension and other variables, such as smoking, age, gender, and family history of diabetes. The results suggest that hypertension is an important public-health problem among high school students. The results also showed that the body mass index was an important parameter in hypertension in such a study group. Researchers should consider overweight a causative risk factor for development of hypertension in early-onset groups.

Risk factors for depression in the first postnatal year: a Turkish study.

BACKGROUND: The aim of the study was to identify risk factors for depression and to estimate its prevalence in postnatal mothers. METHODS: This cross-sectional and multi-centre study was carried out on 1,350 Turkish women in their first postnatal year. Measures included a structured questionnaire and the Turkish version of the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: Of the women, 31.1% had a score of 13 or higher on the EPDS. The mean score and standard deviation was 9.8+/-5.7. In the multivariate analysis, EPDS scores were significantly associated with economic status, access to support from family members and close friends, emotional distress at the pregnancy, whether the pregnancy was planned, health problems during pregnancy, the perceived standard of baby care after delivery, and mental disorder before and during pregnancy. CONCLUSION: The prevalence of EPDS-based depression among Turkish women in postnatal the period was high, and was associated with several social, economic and demographical factors.

The prevalence of diabetes and impaired glucose tolerance in Sivas, Central Anatolia, Turkey.

OBJECTIVE: The aim of this study was to determine type 2 diabetes, impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) prevalence in Sivas, Turkey. RESEARCH DESIGN AND METHODS: This cross-sectional study was conducted in the city center of Sivas. The study population of 771 subjects was selected by the cluster sampling method from 115,998 individuals aged > or =30 years. Participants with fasting venous plasma glucose concentrations <100 mg/dl were classified as "normal." Diabetes was diagnosed in participants if they had fasting blood glucose levels > or =126 mg/dl. An oral glucose tolerance test (OGTT) was performed in subjects with fasting blood glucose levels > or =100 mg/dl and <126 mg/dl. RESULTS: According to the fasting blood glucose levels of the 771 subjects, 44 (5.7%) had diabetes. OGTTs were performed in 80 (10.4%) subjects. According to OGTT results, there were 5 subjects with diabetes, 20 subjects with IGT (2.6%), and 55 subjects with IFG (7.1%). The combined prevalence of IFG and IGT was 9.7%. After OGTT, the total number of diabetic subjects was determined to be 49 (6.4%). Twenty-four (3.1%) of the subjects had a previous diagnosis of diabetes. Multivariate analyses showed that age, sex, hypertension, cigarette smoking, obesity, and family history of diabetes were risk factors for type 2 diabetes (P < 0.05). CONCLUSIONS: Diabetes incidence increases with changes in dietary habits and lifestyle. Education is particularly important for public health, as the community may then have required knowledge about the disease and its risk factors.

The prevalence of sleep related disorders in Sivas, Turkey.

The prevalence of sleep-related disorders (SRD) in adults in Turkey is unknown. The main objective of our study was to assess the prevalence of SRD in Sivas, Turkey. Adults living in Sivas, a city of Turkey from the central region of Anatolia at 20-107 years of age, in both genders, of the 5339 persons, who attended the survey 2638 (49.4%) were male and 2701 (50.6%) were female. The prevalence of insomnia, habitual snoring, obstructive sleep apnea (OSA) and day time hyper somnolence was 40.3%, 37.0%, 6.4%, 24.0% respectively. The prevalence rates of narcolepsy and nocturnal myoclonus was 30.6%, 40.1% respectively. There was a statistical significance between the persons of above 60 years old and another age groups (p< 0.05). But we did not find any significant difference between smokers and non-smokers, also between males and females about SRD prevalence (p> 0.05). However, sleep apnea prevalence was about 9 times higher in the persons suffering from hypertension than without hypertension. Also sleep apnea prevalence was 12 times higher in the persons suffering from overweight. This study has shown that sleep-disordered breathing (SDB) prevalence in Turkey is as high as in other countries and may be more common.

Doping and performance enhancing drug use in athletes living in sivas, mid-anatolia: a brief report.

The aim of this study was to determine the rate of doping and performance enhancing drug use in athletes in Sivas, Turkey, and to analyze the main reasons for the use. This was a cross-sectional study based on a self-report questionnaire. The subjects filled the questionnaires under the supervision of the investigators during interviews. This questionnaire included 24 items describing the population in terms of demographics, sport practice, doping in sport and substance use. Moreover, we assessed the frequency of doping drug use. The number of respondents was 883, of which 433 athletes and 450 healthy non-athletes (control group). The mean age of the total volunteers was 21.8 ± 3.7 yrs. The male and female ratios were 78.2% and 21.8% respectively. Doping and performance enhancing drug usage rate was 8.0% (71cases in 883 subjects). Doping drug use among the athletes was significantly (p < 0.05) higher (14.5%) compared with the non-athletes (1.8%). The agents used were anabolic steroids in 60.5%, l-carnitene in 12.7%, erythropoietin in 5.4%, Na-bicarbonate in 11.3% and creatinine in 14.1% of 71 cases. The reasons for doping use were to have a better body condition in 34 cases (47.9%) and to solve weight (gaining or loosing) problems in 8 (11.3%) cases. Since the potential side effects of doping drugs are not satisfactorily familiar to the most users, the education of athletes on the matter must be a top priority. Key PointsDoping and performance enhancing drug use was 71 (8.0%) in 883 subjects, and it was significantly higher (14.5%) in the athletes compared with the non-athletes (1.8%) in Sivas, Turkey.The rate of athletes who experienced such drugs at least once in their life was 29.0%.The 52.4% of doping and performance enhancing drug users accepted that they were unaware of the drugs full and/or potential side effects.

The distribution of symptoms of attention-deficit/hyperactivity disorder and oppositional defiant disorder in school age children in Turkey.

OBJECTIVE: The aim of this study was to determine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) in school age children in Sivas province centre and to examine the distribution of symptoms according to subtypes. METHOD: The study population was made up of 1425 children between the ages of 6 and 15 from eight primary schools selected by random sampling method in Sivas province centre. All students were given a questionnaire prepared according to DSMIV criteria that was completed by their parents or teachers. This form includes 18 symptoms of ADHD and eight symptoms of ODD. Student's t-test and variance analysis were used for statistical evaluation. RESULTS: A prevalence of 8.1% was found for ADHD in our study. According to subtypes, 32.2% of these were "inattentive", 40% were "hyperactive" and 27.8% were combined type. A prevalence of 11.5% was found for ODD. The boy/girl ratio was > 1 for both ADHD and ODD, and 52.2% of those with ADHD were established as having ODD at the same time. CONCLUSIONS: The prevalence of ADHD and ODD in primary school children was not considered to be small. Studies concerning the distribution of symptoms in different societies, cultures, and viewpoints and identification of children with this type of problem are beneficial for early diagnosis and prophylactic treatment.

The association of biomass fuel combustion on pulmonary function tests in the adult population of Mid-Anatolia.

OBJECTIVES: To assess the association of biomass as domestic energy source on respiratory function in rural areas of Mid-Anatolia in Turkey where biomass use is frequent. METHODS: In a cross-sectional study, pulmonary functions measurements of 112 cow-dung users and 153 modern energy source users, all non-smokers, were assessed and compared. Several sociodemographic factors were assessed by questionnaire, and ventilatory function measurements included forced expiratory volume in one second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio and the flow between the first 25 and 75 of forced expiratory flow (FEF(25-75)), and were compared, deploying univariate and multivariate methods, between the two groups. RESULTS: The individuals in the biomass exposed and unexposed group were similar regarding demographic characteristics: 67.0% were female (exposed) vs 60.1% (unexposed) with an age range of 17 to 64 (exposed) and 18 to 70 years (unexposed), and with 36% of biomass users having had pulmonary tract infections (20% in non-users). For all pulmonary function test parameters FEV1, FVC, FEV1/FVC, and FEF(25-75) a highly significant (p < 0.0001) reduction was observed in biomass users. A 12.4% (95% confidence interval: 7.0% to 17.7%) reduction in forced vital capacity was observed in multivariate linear regression. CONCLUSIONS: It is well known that biomass combustion is a relevant public health problem. The substantial differences in pulmonary functions associated with biomass use as an energy source observed in this cross-sectional study in non-smokers support that also in rural Turkey measures may be in need to reduce this public health problem.

Prevalence of asthma and related symptoms in Sivas, Central Anatolia.

BACKGROUND: In our clinical experience, asthma is an important health problem in our region, but we did not know its prevalence. OBJECTIVE: The main objective of our study was to assess the prevalence of asthma in Sivas, a city in Central Anatolia. METHODS: A cross-sectional study was performed using a screening questionnaire adopted from European Community Respiratory Health Survey (ECRHS). A total of 5448 adults of both genders between 20 and 107 yr of age living in Sivas, a city in the central region of Anatolia in Turkey, participated in the survey. Of the cohort, 2691 were men (49.4%) and 2757 (50.6%) were women. RESULTS: The mean age was 38.2 yr (SD = 12.7 yr), almost half of the study population was at or younger than 40 yr of age. The prevalence of wheezing in the last 12 months, diagnosis of asthma, asthma attack in the last 12 months, and use of asthma medicine were 20.9%, 4.5%, 4.9%, and 3.4%, respectively. Awakening with chest tightness, with shortness of breath, or with cough were reported as 14.2%, 14.8%, and 22.7%, respectively. The prevalence of respiratory symptoms related to asthma was statistically higher in women than that of men (p = 0.000, OR 1.346, 95% CI: 1.228-1.475). Those who had asthma/allergic symptoms in their family members were significantly younger than others (p: 0.001). CONCLUSIONS: The results of this study demonstrate that symptoms suggestive of asthma are quite common and constitute a major health problem in Sivas, Turkey. This study also showed that, despite a high rate of reported symptoms exists, the rate of diagnosis and treatment of asthma is low among the adult population in Sivas.

Seroprevalence of Brucella in an elderly population in mid-Anatolia, Turkey.

Brucellosis is a widespread infectious disease in the mid-Anatolia regions of Turkey. This study investigated the prevalence of Brucella infection in elderly people of this region. In total, 750 elderly subjects were chosen by a simple random-sampling method. Blood samples were evaluated by the Brucella Wright agglutination test. Brucella seropositivity was detected in 24 (3.2%) of the 750 subjects. Although there was no statistical correlation between Brucella seropositivity and sex or educational level (p > 0.05), seropositivity was statistically significant with subjects exposed to risk factors (p < 0.001). It is concluded that Brucella infection is still an important public-health problem in the cities of mid-Anatolia.
