Pulmonary Physician Consultancy in Emergency Services in Turkiye (PuPCEST) - a cross-sectional multicenter study.

Pulmonology is one of the branches that frequently receive consultation requests from the emergency department. Pulmonology consultation (PC) is requested from almost all clinical branches due to the diagnosis and treatment of any respiratory condition, preoperative evaluation, or postoperative pulmonary problems. The aim of our study was to describe the profile of the pulmonology consultations received from emergency departments in Turkiye. A total of 32 centers from Turkiye (the PuPCEST Study Group) were included to the study. The demographic, clinical, laboratory and radiological data of the consulted cases were examined. The final result of the consultation and the justification of the consultation by the consulting pulmonologist were recorded. We identified 1712 patients, 64% of which applied to the emergency department by themselves and 41.4% were women. Eighty-five percent of the patients had a previously diagnosed disease. Dyspnea was the reason for consultation in 34.7% of the cases. The leading radiological finding was consolidation (13%). Exacerbation of preexisting lung disease was present in 39% of patients. The most commonly established diagnoses by pulmonologists were chronic obstructive pulmonary disease (19%) and pneumonia (12%). While 35% of the patients were discharged, 35% were interned into the chest diseases ward. The majority of patients were hospitalized and treated conservatively. It may be suggested that most of the applications would be evaluated in the pulmonology outpatient clinic which may result in a decrease in emergency department visits/consultations. Thus, improvements in the reorganization of the pulmonology outpatient clinics and follow-up visits may positively contribute emergency admission rates.

Regional distribution of genetic mutation in lung cancer in Turkey (REDIGMA).

INTRODUCTION: The results of standard chemotherapy in lung cancer are not very satisfactory, so it is important to identify genetic mutations that provide targeted therapies. Recent reports have suggested influences of racial difference on the frequency of mutation in lung cancer. We aimed to determine the frequency and regional distribution of genetic mutations of non-small cell lung cancer (NSCLC) in Turkey. MATERIALS AND METHODS: Regional distribution of genetic mutations in lung cancer in Turkey (REDIGMA) study was carried out as a prospective, cross-sectional, observational study in a large number of centers in which lung cancer patients were followed and could perform genetic mutation analysis on patients' biopsy materials. RESULT: The 703 patients (77.7% male, mean age 63.3 ± 12.5 years) who were diagnosed as NSCLC from 25 different centers were included in the study. Tumor samples from patients were reported as 87.1% adenocarcinoma, 6.4% squamous cell carcinoma and 6.5% other. Mutation tests were found to be positive in 18.9% of these patients. The mutations were 69.9% EGFR, 26.3% ALK, 1.6% ROS and 2.2% PDL. Mutations were higher in women and non-smokers (p<0.000, p<0.001). Again, the frequency of mutations in adenocarcinoma was higher in metastatic disease. There was no difference between the patient's age, area of residence, comorbidity and clinical stage and mutation frequency. CONCLUSIONS: Our study revealed that the EGFR mutation rate in Turkey with NSCLC was similar to East European, African-American and Caucasian patients, and was lower than in East Asia.

Association between blood pressure, inflammation and spirometry parameters in chronic obstructive pulmonary disease.

BACKGROUND/AIMS: Many systems including the cardiovascular system (ischemic heart diseases, heart failure, and hypertension) may act as comorbidities that can be seen during the course of chronic obstructive pulmonary disease (COPD). Comorbidities affect the severity and prognosis of COPD negatively. Nearly 25% of patients with COPD die due to cardiovascular diseases. In this study, we aimed to evaluate the relationship between the blood pressure, inflammation, hypoxia, hypercapnia, and the severity of airway obstruction. METHODS: We included 75 COPD patients in the study with 45 control cases. We evaluated age, sex, body mass index, smoking history, C-reactive protein levels, 24-hour ambulatory blood pressure Holter monitoring, arterial blood gas, and respiratory function tests of the patient and the control groups. RESULTS: In COPD patients, the night time systolic, diastolic blood pressures and pulse per minute and the mean blood pressures readings were significantly elevated compared to the control group (p < 0.05). In the correlation analysis, night time systolic pressure was associated with all the parameters except forced expiratory volume in 1 second (FEV1%). Diastolic blood pressure was associated with pH and HCO3 levels. The mean night time, day time pulse pressures and 24- hour pulse per minute values were also associated with all the parameters except FEV1%. CONCLUSION: In this study we found that parameters of systolic and diastolic blood pressures and pulse pressures were significantly elevated in COPD patients compared to the control groups. Blood pressure was associated blood gas parameters and inflammation parameters in COPD patients. This, in turn, may cause understanding of the pathophysiology of COPD and its complications.

Spontaneous rib fractures.

BACKGROUND: Other than trauma, rib fracture can occur spontaneously due to a severe cough or sneeze. In this study, patients with spontaneous rib fractures were analyzed according to age, sex, underlying pathology, treatment, and complications. METHODS: Twelve patients who presented between February 2009 and February 2011 with spontaneous rib fracture were reviewed retrospectively. The patients' data were evaluated according to anamnesis, physical examination, and chest radiographs. RESULTS: The ages of the patients ranged from 34 to 77 years (mean 55.91 ± 12.20 years), and 7 (58.4%) were male. All patients had severe cough and chest pain. The fractures were most frequently between 4th and 9th ribs; multiple rib fractures were detected in 5 (41.7%) patients. Eight (66.7%) patients had chronic obstructive pulmonary disease, 2 (16.7%) had bronchial asthma, and 2 (16.7%) had osteoporosis. Bone densitometry revealed a high risk of bone fracture in all patients. Patients with chronic obstructive pulmonary disease or bronchial asthma had been treated with high-dose steroids for over a year. CONCLUSIONS: Spontaneous rib fracture due to severe cough may occur in patients with osteoporosis, chronic obstructive pulmonary disease, or bronchial asthma, receiving long-term steroid therapy. If these patients have severe chest pain, chest radiography should be performed to check for bone lesions.

Factors related to microalbuminuria in patients with chronic obstructive pulmonary disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by inhaled particles and gases inducing chronic inflammation of the airways accompanied by a not fully reversible airflow limitation. Systemic inflammation has an important role in the pathogenesis of COPD. In parallel, several comorbidites can be observed. Microalbuminuria is related to endothelial dysfunction. Microalbuminuria was increased in exacerbation periods of COPD. OBJECTIVES: The aim of the study was evaluate to the presence of microalbuminuria (MA) in patients with chronic obstructive pulmonary disease (COPD) and its relationship to inflammation, arterial blood gas parameters and 24-hour ambulatory blood pressure alterations. MATERIAL AND METHODS: Seventy COPD patients and 40 healthy volunteers were enrolled in the study. 24-h ambulatory blood pressure monitoring (ABPM) results, including pressure and pulse rates of the subjects were recorded and the cases were classified as "dipper" if a normal fall of more than 10% in blood pressure was observed at night and "non-dipper" if not. Routine renal function tests were performed, C-reactive protein (CRP) values were examined and urine samples were obtained to scrutinize the presence of MA. Patients were allocated into two groups, those with and without MA. The spirometry and arterial blood gas results of the patients were recorded. RESULTS: The urinary albumin creatinin ratio (64.8 ± 91.8), CRP (21 ± 14.8), nocturnal systolic and diastolic blood pressure (118 ± 14 and 72 ± 10), nocturnal and diurnal pulse (87 ± 17 and 90 ± 14), nocturnal pulse pressure (49 ± 11), mean pulse (89 ± 15), mean pulse pressure (48 ± 10) and the number of non-dipper subjects (65) were found significantly higher in the COPD group than in the control group (10.6 ± 6, 5.4 ± 2.4, 105 ± 6 and 68 ± 7, 70 ± 10 and 78 ± 11, 42 ± 1, 75± 11, 42 ± 7 and 5, respectively); (p < 0.001, < 0.001, < 0.001 and 0.041, < 0.001 and < 0.001, < 0.001, < 0.001, < 0.001 and < 0.001, respectively). Nocturnal pulse (89 ± 17) and CRP (23.5 ± 14.8) were found to be significantly higher in COPD patients with MA than in COPD patients without MA (78 ± 8 and 8.8 ± 6.3, respectively); (p = 0.021 and < 0.001, respectively). CONCLUSIONS: The facts that CRP, a systemic inflammation marker, and mean nocturnal pulse pressure values were significantly higher in the group with MA among COPD patients, and that ambulatory blood pressure values did not differ between COPD patients with and without MA, suggest both a possible role of inflammation in MA development in COPD patients and a relationship between MA and increased heart rate.

Combined germline variations of thrombophilic genes promote genesis of lung cancer.

BACKGROUND: A large variety of familiar and non-familiar lung carcinomas (LC) are caused by long term exposure to chemical carcinogens that are present in tobacco smoke. We aimed to investigate the prevalence of 5 thrombophilic germ-line mutations in patients with lung carcinomas. MATERIALS AND METHODS: A total of 52 LC patients and 212 healthy controls from same population were analyzed for FV Leiden, factor V H1299R (R2), PAI-1, MTHFR C677T, MTHFR A1298C, ACE I/D, and Apo E genes and compared. RESULTS: Overall, heterozygous and/or homozygous point mutations in FV Leiden Apo E2, PAI-1 and MTHFR C677T genes were associated with LC in the current cohort. There was no meaningful association between LC and ACE I/D gene markers. CONCLUSIONS: The current results showed that LC is related to combined thrombophilic gene mutations and individuals with homozygosity of 4G in PAI-1 and MTHFR C677T genes and heterozygosity of FV Leiden, Apo E4 genes have a germ-line risk for LC tumorigenesis.

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 practice of respiratory disability assessment in a university hospital: the analysis of 136 patients]. / Bir üniversite hastanesinde solunumsal maluliyet degerlendirme pratigi: 136 hastanin analizi.

INTRODUCTION: This study, to examine the outcomes of the respiratory disability assessment in our clinic. MATERIALS AND METHODS: The reports of 136 patients who attended the chest diseases clinic between January 2010 and June 2011 for the assessment of the respiratory disability were examined retrospectively. RESULTS: Of 10.457 patients who presented in 18 months, 136 (1.3%) requested the assessment of the respiratory disability. The patients' average age was 51 ± 12 years and 118 (87%) were male. Farmers constituted 19.8% of the patients and mine and foundry workers 10.7% of the patients. The most frequent symptoms were dyspnea (91.2%) and cough (76.5%). The most frequent radiological pattern was reticular and nodular opacities (38.2%). The workup led to a diagnosis of chronic obstructive pulmonary disease in 64 patients (47%) and of interstitial pulmonary disease/pneumoconiosis in 19 (14%) patients. No respiratory disease was found in 19 patients. Among 44 (32.4%) patients for whom disability rate was calculated, 8 (18.2%) had an incapacity rate of 60% or higher and 13 had 0%. The disability rates showed positive correlations with age, the duration of the respiratory symptoms and PaCO2 level (respectively r= 0.395, p= 0.008; r= 0.391, p= 0.009; r= 0.790, p< 0.001), and negative correlations with FVC, FEV1 and PaO2 levels (respectively r= -0.681, p< 0.001; r= -0.766, p< 0.001; r= -0.661, p= 0.003). Linear regression analysis showed that high PaCO2 value is a determinant for a high disability rate (r= 0.902, p= 0.014). Furthermore, smokers had higher disability rates than non-smokers (p< 0.001). CONCLUSION: We believe that new evidence-based guidelines that will resolve the medicolegal and social obscurities are needed.

Chest X-ray and bacteriology in the initial phase of treatment of 800 male patients with pulmonary tuberculosis.

OBJECTIVE: To evaluate chest X-rays of patients with pulmonary tuberculosis and to determine whether the extent of radiographic lesions correlates with bacteriological parameters. METHODS: In this retrospective, descriptive study, we evaluated chest X-rays, as well as AFB detection by smear microscopy and culture for Mycobacterium tuberculosis, initially and during the first two months of treatment, in 800 male patients hospitalized between 1995 and the present at a 250-bed hospital in northwestern Turkey. RESULTS: The initial mean ESR was 58 ± 37 mm/h. Initial sputum smears and cultures were positive in 83.8% and 89.5% of the patients, respectively. After the first month of treatment, the proportion of patients with positive sputum culture was higher among those with cavitary tuberculosis than among those with non-cavitary tuberculosis (53.7% vs. 37.7%, p < 0.001). The number of affected zones was not correlated with age, symptom duration, contact with an active tuberculosis patient, or concomitant diabetes (p > 0.05 for all) but was positively correlated with the ESR (r = 0.23, p < 0.001). During the first and second months of treatment, conversion to smear-negative status was less common in patients with bilateral involvement than in those with unilateral involvement (p < 0.001 and p = 0.002 for months 1 and 2, respectively). Disease extent did not correlate with age, symptom duration, contact with an active tuberculosis patient, or concomitant diabetes but did correlate with delayed bacteriological recovery. CONCLUSIONS: Chest X-ray and bacteriology are valuable tools for the evaluation of pulmonary tuberculosis.

Radiografia torácica e bacteriologia na fase inicial de tratamento de 800 pacientes masculinos com tuberculose pulmonar / Chest X-ray and bacteriology in the initial phase of treatment of 800 male patients with pulmonary tuberculosis

OBJETIVO: Avaliar radiografias de tórax de pacientes com tuberculose pulmonar e determinar se a extensão das lesões radiográficas correlaciona-se com os parâmetros bacteriológicos. MÉTODOS: Neste estudo descritivo e retrospectivo; foram avaliadas radiografias de tórax, baciloscopias para BAAR e culturas de escarro para Mycobacterium tuberculosis no momento basal e durante os dois primeiros meses de tratamento. A amostra foi composta por 800 pacientes masculinos internados entre 1995 até o presente em um hospital com 250 leitos no noroeste da Turquia. RESULTADOS: A VHS média inicial foi de 58 ± 37 mm/h. Inicialmente, a baciloscopia e as culturas de escarro tiveram resultado positivo em 83,8 por cento e em 89,5 por cento dos pacientes, respectivamente. Após o primeiro mês do tratamento, a proporção de culturas positivas foi maior nos pacientes com doença cavitária do que naqueles sem doença cavitária (53,7 por cento vs. 37,7 por cento; p < 0,001). Não houve correlação do número de zonas afetadas com idade, duração de sintomas, contato com paciente com tuberculose ativa, diabetes concomitante (p > 0.05 para todos), mas houve correlação positiva com VHS (r = 0,23, p < 0,001). Durante o primeiro e o segundo mês de tratamento, a negativação da baciloscopia foi menos frequente nos pacientes com comprometimento bilateral do que naqueles com comprometimento unilateral (p < 0,001 e p = 0,002 para os meses 1 e 2, respectivamente). A extensão da doença não se correlacionou com idade, duração dos sintomas, contato com paciente com tuberculose ativa e diabetes concomitante, mas sim com a recuperação bacteriológica atrasada. CONCLUSÕES: Radiografias de tórax e bacteriologia são ferramentas valiosas na avaliação de tuberculose pulmonar.

An analysis of 214 cases of rib fractures.

INTRODUCTION: Rib fractures are the most common type of injury associated with trauma to the thorax. In this study, we investigated whether morbidity and mortality rates increased in correlation with the number of fractured ribs. MATERIALS AND METHODS: Data from 214 patients with rib fractures who applied or were referred to our clinic between January 2007 and December 2008 were retrospectively evaluated. The patients were allocated into three groups according to the number of fractures: 1) patients with an isolated rib fracture (RF1) (n = 50, 23.4%), 2) patients with two rib fractures (RF2) (n = 53, 24.8%), and 3) patients with more than two rib fractures (RF3) (n = 111, 51.9%). The patients were evaluated and compared according to the number of rib fractures, mean age, associated chest injuries (hemothorax, pneumothorax, and/or pulmonary contusion), and co-existing injuries to other systems. FINDINGS: The mean age of the patients was 51.5 years. The distribution of associated chest injuries was 30% in group RF1, 24.6% in group RF2, and 75.6% in group RF3 (p<0.05). Co-existing injuries to other systems were 24% in group RF1, 23.2% in group RF2, and 52.6% in group RF3 (p<0.05). Two patients (4%) in group RF1, 2 patients (3.8%) in group RF2, and 5 patients (4.5%) in group RF3 (total n = 9; 4.2%) died. CONCLUSION: Patients with any number of rib fractures should be carefully screened for co-existing injuries in other body systems and hospitalized to receive proper treatment.

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.

The association between methylene-tetrahydrofolate reductase gene polymorphism and lung cancer risk.

This study aimed to determine the relation between methylene-tetrahydrofolate reductase (MTHFR) gene polymorphism and lung cancer risk and the frequency of this polymorphism. The study involved 64 lung cancer patients (the study group) with definitive diagnosis and 61 noncancerous subjects (the control group). MTHFR C677T and A1298C mutation analysis was made using DNA isolated from peripheric blood and multiplex PCR and reverse hybridization strip test. Eighty-four percent of the patients were male. The age, gender, and history of alcohol use of the patients and control group were statistically similar. While MTHFR 677T and 677C allele frequency was 0.33 and 0.67 in the patients respectively, it was 0.29 and 0.71 in the control group. The frequencies of MTHFR 1298C and 1298A were 0.33 and 0.67 in the patients, and it was 0.31 and 0.69 in the control group respectively. When MTHFR 677TT and 677CT genotypes were compared with 677CC genotype, lung cancer risk was 2.4 times higher in the 677TT genotype. When MTHFR 1298AC and 1298CC genotypes were compared with 1298AA genotype, lung cancer risk was 1.5 times higher in 1298CC genotype. According to the results, allele frequency of homozygote T and C was high in lung cancer patients. It was 3.05 and 1.29 times higher in smokers than in non-smokers, and 3.05 and 1.64 times higher in males than in females; 3.0 and 2.44 times higher in those with non-small cell lung cancer than in those with small-cell lung cancer.

Association of deep venous thrombosis with prothrombotic gene polymorphism identified in lung cancer cases.

Venous thrombosis is a significant cause of morbidity and mortality in patients with malignancies. We aimed to investigate the association between prothrombotic gene polymorphisms detected in lung cancer cases and deep venous thrombosis (DVT). Totally 66 patients with an established diagnosis of lung cancer, of which 33 developed DVT, were enrolled. Multiplex PCR technique and reverse hybridization strip assay were performed on DNA extracted from peripheral blood, in order to analyze prothrombin G20210A, factor V G1691A, methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C, angiotensin converting enzyme (ACE), plasminogen activator inhibitor-1 (PAI-1), and glycoprotein IIIa (Gp IIIa) gene mutations. Among prothrombotic gene polymorphisms investigated in this study, the commonest ones were PAI-1 4G/5G (56% heterozygous, 39% homozygous) and ACE gene mutations (58% heterozygous, 17% homozygous). The presence of homozygous MTHFR A1298C mutation was significantly associated with DVT (P=0.020). Comparing the lung cancer patients with and without DVT, only MTHFR A1298C gene polymorphism differed significantly (P=0.040). We determined a higher rate of prothrombotic gene mutations in lung cancer patients who developed DVT. However, statistical significance was achieved only for MTHFR A1298C gene mutation. Therefore, nongenetic factors for disturbance of hemostatic metabolism should also be considered in lung cancer patients.

An analysis of 214 cases of rib fractures

INTRODUCTION: Rib fractures are the most common type of injury associated with trauma to the thorax. In this study, we investigated whether morbidity and mortality rates increased in correlation with the number of fractured ribs. MATERIALS AND METHODS: Data from 214 patients with rib fractures who applied or were referred to our clinic between January 2007 and December 2008 were retrospectively evaluated. The patients were allocated into three groups according to the number of fractures: 1) patients with an isolated rib fracture (RF1) (n = 50, 23.4 percent), 2) patients with two rib fractures (RF2) (n = 53, 24.8 percent), and 3) patients with more than two rib fractures (RF3) (n = 111, 51.9 percent). The patients were evaluated and compared according to the number of rib fractures, mean age, associated chest injuries (hemothorax, pneumothorax, and/or pulmonary contusion), and co-existing injuries to other systems. FINDINGS: The mean age of the patients was 51.5 years. The distribution of associated chest injuries was 30 percent in group RF1, 24.6 percent in group RF2, and 75.6 percent in group RF3 (p<0.05). Co-existing injuries to other systems were 24 percent in group RF1, 23.2 percent in group RF2, and 52.6 percent in group RF3 (p<0.05). Two patients (4 percent) in group RF1, 2 patients (3.8 percent) in group RF2, and 5 patients (4.5 percent) in group RF3 (total n = 9; 4.2 percent) died. CONCLUSION: Patients with any number of rib fractures should be carefully screened for co-existing injuries in other body systems and hospitalized to receive proper treatment.

The association between plasma D-dimer levels and community-acquired pneumonia.

BACKGROUND: Plasma D-dimer levels are directly related to the intra- and extra-vascular coagulation that occurs in acute and chronic lung damage in patients with community-acquired pneumonia (CAP). OBJECTIVES: This study examines the relationship between the severity of community-acquired pneumonia and D-dimer levels. In addition, the study examines the correlations among community-acquired pneumonia, the radiological extent of the disease and mortality. METHODS: The Pneumonia Severity Index was used to classify patients into five groups. Patients were treated at home or in the hospital according to the guidelines for community-acquired pneumonia. Blood samples were taken from the antecubital vein with an injector and placed into citrated tubes. After they were centrifuged, the samples were evaluated with the quantitative latex method. RESULTS: The study included 60 patients who had been diagnosed with community-acquired pneumonia (mean age 62.5 +/- 11.7) and 24 healthy controls (mean age 59.63 +/- 6.63). The average plasma D-dimer levels were 337.3 +/- 195.1ng/mL in the outpatient treatment group, 691.0 +/- 180.5 in the inpatient treatment group, 1363.2 +/- 331.5 ng/mLin the intensive care treatment group and 161.3 +/- 38.1ng/mL in the control group (p<0.001). The mean D-dimer plasma level was 776.1 +/- 473.5ng/mL in patients with an accompanying disease and 494.2 +/- 280.1 ng/mL in patients without an accompanying disease (p<0.05). CONCLUSIONS: Plasma D-dimer levels were increased even in community-acquired pneumonia patients who did not have an accompanying disease that would normally cause such an increase.

A frame-shift mutation in the SLC34A2 gene in three patients with pulmonary alveolar microlithiasis in an inbred family.

Pulmonary alveolar microlithiasis (PAM) is a rare disease characterized by the presence of small calculi in the alveolar space. The SLC34A2 is thought to be responsible for the disease. We encountered three siblings of an inbred family who have PAM. We examined the family of the proband who was admitted with dyspnea on exertion and cough, and eventually was diagnosed with PAM. Genetic analysis revealed that both parents (a consanguineous marriage) of the proband were carriers with heterozygous mutation of SLC34A2 gene, and three of their children were diagnosed with PAM with homozygous mutation in the SLC34A2 gene. These findings suggest that impaired activity of the SLC34A2 gene may be responsible for familial PAM.

[Symptom prevalence of obstructive sleep apnea-hypopnea syndrome in health-care providers in central Sivas]. / Sivas il merkezi saglik çalisanlarinda obstrüktif uyku apne-hipopne sendromu semptom prevalansi.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is the most common sleep disorder that can lead to serious complications. Polysomnography (PSG) is the gold standard for the diagnosis of OSAHS. Unfortunately, PSG studies are expensive, time-consuming, requiring special team and equipment. Therefore, it is possible to determine the cases likely to have OSAHS requiring at least PSG by type A studies. There isn't enough data about the prevalence of OSAHS in Turkey. The aim of this study was to estimate the symptom prevalence of OSAHS in health-care providers in central Sivas. The questionnaire asking demographic features, additional diseases, habits, the symptoms related with OSAHS was performed in total of 1202 health care providers. We also performed Epworth sleepiness scale (ESS) to determine excessive daytime sleepiness. Snoring was detected in 267 participants. Snoring rates were 38% and 10.9% in men and in women, respectively. The rate of witnessed sleep apnea in all cases was 4.4% (n=53).
