Case report of a novel alpha1-antitrypsin null variant in Türkiye: Q0RIZE.

BACKGROUND: Alpha1-antitrypsin (AAT) is a serine protease inhibitor that serves as a counterbalance to the activity of elastases, e.g., neutrophil elastase in lung tissue. AAT deficiency (AATD) is a rare disorder usually arising from mutations to the SERPINA1 gene that codes for AAT. The most common AATD alleles are S and Z which produce ~ 40% and ~ 90% reductions in serum AAT, respectively. Rare genetic variants (> 500 identified) can also be associated with mild to severe AATD. RESULTS: This report describes a novel mutation of SERPINA1 producing AATD, which we have designated, Q0RIZE. This mutation was identified in a 44-year-old woman admitted with massive hemoptysis and treated with bronchial artery embolization. Computed tomography revealed centriacinar and panacinar emphysema with prominent air entrapment, atelectasis, and localized bronchiectasis. Serum AAT was < 0.27 g/L (below detection limit). Genetic analysis showed homozygous deletion of exons I to III. CONCLUSIONS: Although many SERPINA1 variants have been identified, variants with large deletions and identified in a homozygous individual, as seen in this case with Q0RIZE, are uncommon. AATD is an underdiagnosed and undertreated disease. Wider screening of COPD patients could result in earlier diagnosis and treatment that could preserve lung function.

Giant lung cavity due to three different pathogens in a patient receiving inhaled salmeterol plus fluticasone propionate for asthma.

INTRODUCTION: High-dose and long-term use of inhaled corticosteroids may cause systemic and local side effects such as opportunistic infections. Here we report a patient with asthma who developed a giant cavity in the lung while using inhaled salmeterol plus fluticasone propionate. CASE STUDY: A 57-year-old female patient presented with a three-week history of cough, hemoptysis, and dyspnea. She had a diagnosis of asthma for 4 years and was using an inhaled salmeterol plus fluticasone treatment intermittently for 2 years. A giant cavity was detected in the patient's chest X-ray. As a result of further investigations, three different microorganisms were isolated from the samples of sputum, bronchial lavage and lung biopsy. RESULTS: Staphylococcus aureus was the first microorganism that was isolated from the sputum and the bronchial lavage. Afterwards, Candida albicans was detected in both the bronchial lavage fluid and the histologic examination of the tissue samples obtained by percutaneous lung biopsy. Appropriate antibiotics and antifungals were prescribed. Moderate clinical and radiological response to the treatment was obtained. During the outpatient follow-up, Mycobacterium tuberculosis growth which was sensitive to all of the major anti-tuberculosis drugs was reported in the mycobacterial culture, and the patient was started on anti-tuberculosis treatment. CONCLUSION: Tuberculosis and other opportunistic infections are a potential consequences of inhaled corticosteroids. Clinicians overseeing such patients need to be vigilant about the need for timely investigations about tuberculosis before and during prescribing medications containing inhaled corticosteroids.

Caregiver Burden in Pulmonary Patients.

Caregiving has become an increasingly important medical and social issue in recent decades. We performed a cross-sectional study on pulmonary patients and accompanying informal caregivers who were hospitalized in the chest disease ward of a tertiary center in Turkey between January 2020 and April 2021. Informal caregivers were asked to complete the Zarit Caregiver Burden Interview. A total of 141 inpatients (39% female, mean age: 76.8 ± 10.2 years) and their informal caregivers (77% female, mean age: 54 ± 11.9 years) were evaluated. The caregivers were classified as light to medium burden (group 1, burden score ≤40) and medium to heavy burden (group 2, burden score >40). The mean burden score was 35.7 ± 13.3 points. The number of female caregivers was higher in group 2 (p = 0.025). There was a positive correlation between the burden score and female gender (p = 0.002) and the number of chronic diseases of caregivers (p = 0.020). Statistical analysis revealed a negative correlation between the burden score and the level of education (r = > -0.174, p = 0.040). Caregiver burden is related to the characteristics of the caregiver rather than those of the patient being cared for. Female caregivers with lower education and more than one chronic disease perceive a higher caregiver burden.

The value of the platelet count and platelet indices in differentiation of COVID-19 and influenza pneumonia.

It is difficult to distinguish coronavirus disease-2019 (COVID-19) from other viral respiratory tract infections owing to the similarities in clinical and radiological findings. This study aims to determine the clinical importance of platelet count and platelet indices in the differentiation of COVID-19 from influenza and the value of these parameters in the differential diagnosis of COVID-19. The medical records of the patients and the electronic patient monitoring system were retrospectively analyzed. Demographic characteristics, admission symptoms, laboratory findings, radiological involvement, comorbidities, and mortality of the patients were recorded. Forty-three patients diagnosed with influenza and 54 diagnosed with COVID-19 were included in the study. The average age of the COVID-19 patients was lower than that of the influenza patients (influenza: 60.5 years, COVID-19: 52.4 years; pp = 0.024),.024), and the male gender was predominant in the COVID-19 group (influenza: 42%, COVID-19: 56%). According to laboratory findings, the mean platelet volume (MPV) and MPV/platelet ratio were statistically significantly lower, whereas the eosinophil count and platelet distribution width levels were significantly higher (p < 0.05) in the COVID-19 group. It was found that the most common symptom in both groups was dyspnea and that the symptom was more prevalent among influenza patients. In the diagnosis of COVID-19, the platelet count and platelet indices are easily accessible, inexpensive, and important parameters in terms of differential diagnosis and can help in the differentiation of COVID-19 from influenza during seasonal outbreaks of the latter.

The relation between retrobulbar blood flow and posterior ocular changes measured using spectral-domain optical coherence tomography in patients with obstructive sleep apnea syndrome.

PURPOSE: To investigate the effect of posterior ocular hemodynamics on the retinal nerve fiber layer (RNFL), choroid thickness (CT) and central macular thickness (CMT) in patients with obstructive sleep apnea syndrome (OSAS) and to reveal the association with glaucomatous optic neuropathy. METHODS: The research was planned as a prospective, randomized study. The ophthalmic, retinal and posterior ciliary artery pulsatile index (PI) and resistive index (RI) were measured by colored Doppler sonography. RNFL thickness, CMT and CT were then measured by spectral-domain optical coherence tomography. RESULTS: Sixty subjects were divided into four groups-mild, moderate and severe OSAS and a control group. There were 16 subjects in the control group, 14 in the mild OSAS group, 15 in the moderate OSAS group and 15 in the severe OSAS group. Ophthalmic artery and central retinal artery PI and RI values of the OSAS patients did not show statistically significant difference than those of the control group, but posterior ciliary artery (PCA) PI and RI values were significantly higher. In addition, mean, superior and inferior RNFL thickness values were significantly lower than those in the control group. Moreover, the glaucoma prevalence of the OSAS patients in this study was 6.8% and all of these patients were in the severe OSAS group. CONCLUSION: PI and RI values of the PCA, which supplies the optic nerve, show a linear increase as the apnea hypoxia index values in OSAS. As the grade of OSAS improves, this situation leads to a more serious ischemic optic neuropathy. Furthermore, the prevalence of glaucoma in this study is found to be higher in the severe OSAS group.

A rare disease; congenital pulmonary airway malformation in an adult.

Congenital pulmonary airway malformation (CPAM), is a rare disease known as a developmental abnormality of the lower respiratory tract. It may occur in the neonatal period due to respiratory distress and patients usually die in the first few months of life. Rarely, it may remain asymptomatic until adulthood. In this study we describe an adult case and present a review of the literature. A 19-year-old male with no relevant medical history was admitted to our clinic with cough and wheeze. The patient had a history of frequent lower respiratory tract infection during childhood. Chest radiograph revealed a diffuse opacity and volume loss in the right hemithorax. High resolution tomography showed hypoplasia of the right hemithorax, multiple cysts in all of the lobes and segments on the right side, ground glass opacity and interlobular septal thickening of the whole right lung parenchyma. Right pneumonectomy was performed with the pre-diagnosis of congenital pulmonary airway malformation and the pathological examination was compatible with CPAM. CPAM is a rare disease in adulthood. We should consider CPAM in the differential diagnosis of patients with frequent recurrent pulmonary infection and cystic lung lesions. In order to prevent infections and to eliminate the risk of malignancy, surgical treatment should be applied for definite diagnosis and treatment.

[Elevated pleural copeptin levels can distinguish to exudate from transudates]. / Yüksek plevral copeptin düzeyleri eksüdayi transüdadan ayirabilir.

INTRODUCTION: Copeptin is released simultaneously along with arginine-vasopressine as a result of different stimuli from the neurohypophysis. Physiological function of copeptin is still unclear. Increased blood copeptin levels is associated with poor prognosis in many diseases. Pleural effusion is a common clinical condition. The most common causes of pleural effusions are heart failure, parapneumonic effusion, pulmonary embolism and malignacy.Tuberculosis is one of the other major causes of pleural effusion in developing countries. In this study, we aimed to assess whether pleural copeptin level may be a new discriminative biomarker for exudates and transudates pleural effusions. MATERIALS AND METHODS: Research was done at Recep Tayyip Erdogan University School of Medicine in the Department of Chest Diseases. The concentrations of pleural copeptin and typical pleural and serum marker levels were measured in 76 subjects with pleural effusions including 22 transudates caused by congestive heart failure (CHF), and 54 exudates including 18 parapneumonic (PPE), 18 tuberculous pleural effusions (TBPEs), 18 malignant effusions (MPEs). RESULTS: Median pleural fluid copeptin levels were higher in exudates than in transudates (1936 ng/mL and 1313 pg/mL, p value < 0.001). There was no statistical significancy for pleural fluid copeptin levels with in-group exudates (n= 54). Pleural copeptin levels of exudates, with a cut off value of 1469 ng/mL, yielded a 79.6% sensitivity, 81.8% specificity, with an are a under the curve of 0.851. CONCLUSION: Pleural copeptin level is a new biomarker to separate exudates from transudates. Pleural effusion discriminative effect of copeptin is lower than plasma protein level and plasma lactat dehydrogenase (LDH). Pleural copeptin measurement is not recommended for routine clinical use. Pleural copeptin level is not contribute to different iate exudative pleural fluids from each other like PPE, TBPE and MPE.

EXPRESS: LONG COVID: A RISK FACTOR FOR ANXIETY, DEPRESSION, AND SUICIDALITY?

In many Covid 19 survivors, symptoms continue for a long time. The aim of this study is to examine the relationship between long-term effects of COVID-19, levels of anxiety and depression, and suicidal ideation with sociodemographic factors and symptoms. A cross-sectional study conducted on patients who came for control at least 3 months after having COVID-19 disease, in the stable period and still have symptoms after COVID-19. Demographic characteristics, symptoms, The Beck Depression Scale (BDS), The Beck Anxiety Scale (BAS) and suicidal ideation were assessed with a face-to-face questionnaires. A total of 490 patients participated to the study. 30% of patients scored positive on the BDS and 46% scored high on the BAS. Female sex was found as a risk factor. Anxiety and depression were found to be significantly associated with long COVID symptoms. Both BAS and BDS scores were significantly higher in people with suicidality compared to others, and long-term symptoms were found to be statistically associated with this situation. Depression and anxiety are common in cases of long COVID. It is important for healthcare professionals to be aware of these potential mental health consequences especially suicidality and, to provide appropriate support and interventions for individuals with long COVID.

High serum YKL-40 level in patients with COPD is related to hypoxemia and disease severity.

Chronic obstructive pulmonary disease (COPD) is a major health problem with increasing morbidity and mortality throughout the world. YKL-40 is a chitin-binding glycoprotein consisting of 383 amino acids, with a molecular mass of 40 kDa, and its serum level is elevated in inflammatory diseases. YKL-40 is a newly recognized biomarker of inflammation and has not been thoroughly investigated in COPD. The aim of the study is to investigate the relationship between serum YKL-40 levels and severity of COPD. The study population consisted of 52 patients with COPD with the mean age of 60.2 ± 10.1 years. The serum YKL-40 level increased significantly with increasing age (p = 0.022, r = 0.346). In COPD patients, high serum YKL-40 level is correlated to low forced expiratory volume at 1 second (FEV1, percent of predicted) (r = -0.277, p = 0.047). Moreover, high serum YKL-40 level is correlated to low arterial oxygen pressure (PaO2, mmHg) (r = -0.387, p = 0.005). The mean serum YKL-40 level was found as 243.1 ± 129.2 ng/ml in COPD patients with desaturation during 6-minute walk test (6MWT) and this value was higher than the mean serum YKL-40 level (155.8 ± 59.1 ng/ml) of COPD patients without desaturation during 6MWT (p = 0.004). This study demonstrated that high serum YKL-40 levels were correlated to severity of COPD. We propose that circulating YKL-40 levels could be a biomarker for hypoxemia and decline in lung function.

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

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

A case with multisystemic involved of Tuberculosis.

Cases of tuberculosis with multisystemic involvement are rarely reported and these are often children and patients with AIDS whose and immune system is suppressed. Tuberculosis can mimic and present with various disorders. A 18-year-old Georgian male patient was admitted to the hospital with double vision, swelling and wound on the 3rd digit of the right hand. We defined the multisystemic tuberculous disease including orbital bone with soft tissue tuberculosis, tuberculosis spondylitis, tuberculosis dactylitis, scrofuloderma and pulmonary tuberculosis in these patient.

'COVID-Somnia' in healthcare workers during the pandemic.

OBJECTIVES: Sleep disorders associated with COVID-19 pandemic are termed as 'COVID-somnia.' In this study, we sought to assess the prevalence of COVID-somnia in healthcare workers, establish the factors that trigger this condition, and to investigate its relationship with anxiety and depression symptoms. METHODS: This cross-sectional study was conducted between April 2021 and June 2021, and it included healthcare workers who served during the pandemic. Participants' demographic data, Beck Depression and Anxiety Inventories, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Insomnia Severity Index (ISI) were used, and the results were statistically analyzed. Multiple analyses of factors affecting ESS and ISI scores were evaluated using binary logistic regression model and PSQI score were analyzed using a multiple linear regression model. RESULTS: A total of 1,111 healthcare workers who served during the pandemic voluntarily enrolled to the study. The mean age was 37.3 ± 8.48 years, and 63.5% were females. Our study showed that the healthcare workers, evaluated with the PSQI, experienced a deterioration of sleep quality. Primary factors affecting this are working on the front line, the presence of chronic diseases, depression, and anxiety. Regression analyses identified depression and anxiety as the common factors affecting ESS, ISI, and PSQI scores. CONCLUSION: Raising awareness regarding COVID-somnia among healthcare workers, who play a leading role in curbing the pandemic, would reduce sleep disturbances, depression, and anxiety. It would also contribute to the planning and implementation of preventive and therapeutic mental health programs with a multidisciplinary approach.

Complex craniofacial reconstruction with prostheses as an alternative method to autogenous reconstruction.

Reconstruction of facial organ and tissue losses using autogenous tissue is a permanent and effective method in plastic surgery. However, in cases where the patient's general condition does not allow for surgical reconstruction or where the patient is in need of reconstruction of complex organs such as the eye, nose, or ear, an epithesis can be considered as an alternative to treatment with autogenous tissue. The purpose of this study was to investigate the factors affecting the success rate of facial reconstructions with an externally retained prosthesis in relation to the defect location and radiotherapy treatment. Between September 2004 and October 2008, 11 patients with facial tissue defects who had been treated with an osseointegrated implant system were evaluated. Because 1 patient with a midfacial defect died 3 months after the surgery, this case was excluded, leaving a total of 10 patients for evaluation. Five patients' facial defects were located in the ear, 2 patients had nasal defects, and 3 patients had defects in the midfacial region. The total numbers of implants applied to these regions were 13, 6, and 25, respectively. A total of 44 implants applied were followed for an average period of 52.4 months (between 6 and 77 months). In cases where the reconstruction was considered satisfactory, no infections were observed, and there were no implant losses in the mastoid region. Implant losses were observed in a total of 14 implants (31.8%), 2 of which were in the glabellar region (4.5%), and 12 were in the midfacial region (27.2%). The implant losses were observed between the first and 18th postsurgical months (with an average of 6 months). The remaining implants were sufficient to retain the prostheses. Because of these results, the use of implant-assisted epitheses can be considered a viable alternative in patients whose facial defects cannot be corrected through reconstructive surgery performed with autogenous tissue.

Thyroid Gland Disease as a Comorbid Condition in COPD.

INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is one of the most common causes of morbidity and mortality worldwide. The disease is characterized by progressive airway inflammation, which not only affects the airways but also has systemic effects that are associated with comorbidities. Although comorbid conditions such as hypertension and coronary artery disease are very well-known in COPD patients, diseases of the thyroid gland have not been sufficiently studied. Therefore, thyroid diseases are not considered among the comorbid conditions of COPD. The purpose of this study was to determine the thyroid gland disease (TGD) prevalence in COPD and associated factors. Materials and Method. The study included 309 (297 (96%) male) patients. The patients were subjected to spirometry and thyroid function tests (TFT) in the stable period. The thyroid gland disease they were diagnosed with was recorded after face-to-face meetings and examining their files. RESULTS: The mean age of the patients who were included in the study was 65.9 ± 9.8 (40-90). Thyroid disease was determined in 68 (22%) individuals. There were hypothyroidism in 7 (2%), euthyroidism in 45 (15%), and hyperthyroidism in 16 (%5) patients. No relationship was found between the severity of airflow limitation and the prevalence of TGD. CONCLUSION: Thyroid abnormalities are commonly observed in COPD. The most frequently encountered TGDs are euthyroid multinodular goiter, euthyroid sick syndrome (ESS), and toxic multinodular goiter.

Rate of History of Tuberculosis Among Healthcare Workers in Turkey: A Cross-Sectional Study.

OBJECTIVES: Healthcare workers (HCWs) possess a high risk for both latent tuberculosis infection (LTBI) and active disease. This study aimed to investigate tuberculosis (TB) disease history in hospital staff working in healthcare institutions in the Eastern Black Sea Region of Turkey. MATERIAL AND METHODS: This study included 460 HCWs employed in 5 hospitals in the Eastern Black Sea Region of Turkey. Between May 01 and July 31, 2016, the participants were asked to answer a questionnaire, including data about TB history. The data about family TB history, Bacilli Calmette-Guerin (BCG) vaccination, or tuberculin skin test (TST) application before starting work were also evaluated. RESULTS: Of the 460 participants, 69.3% were women (n=319) and 30.7% (n=141) were men. The mean age was 32 (17-63) years. A total of 8 participants (1.7 %) had TB history. There was no statistically significant relationship between TB history and age, sex, body mass index (BMI), smoking habits, or presence of comorbidities (p>0.05 for all variables); family history of TB (p<0.001) and TST positivity (p<0.001) were significantly higher in participants with a TB history. Each participant was checked for the presence of both BCG scar and TST positivity. No difference was noted between positive TB history and negative HCWs (p>0.05). The duration of work (years) was higher in participants with a TB history. The p value was very close but did not reach the limits of significance (p=0.059). CONCLUSION: In this study, the rate of TB among HCWs was 1.7% (8 of 460 HCWs). Family history of TB and TST positivity are strong predictors of TB in HCWs.

Weight Loss as the First-Line Therapy in Patients with Severe Obesity and Obstructive Sleep Apnea Syndrome: the Role of Laparoscopic Sleeve Gastrectomy.

PURPOSE: The objective of this study is to investigate the effects of laparoscopic sleeve gastrectomy (LSG) on the polysomnographic parameters related to OSAS. MATERIALS AND METHODS: We conducted this 3-year prospective cohort study in a tertiary care center between December 2016 and December 2019. In total, we enrolled 31 patients with severe obesity who underwent full-night polysomnography (PSG) before LSG. Later, the patients were re-evaluated by full-night PSG 12 months after the surgery. RESULTS: The mean age of the patients was 44.1 ± 9.6 years. The mean body mass index (BMI) decreased significantly from a mean value of 49.8 ± 8.5 kg/m2 at baseline to 33.2 ± 8.2 kg/m2 and a percent BMI (%BMI) reduction of 33.8 ± 10.4% and a percent total weight loss (%TWL) of 35.4 ± 10.8% was achieved on the same day of the postsurgical PSG (p < 0.001). There was a remarkable improvement in the AHI (baseline: 36.1 ± 27.1, 12 months after the surgery: 10.3 ± 11.8; difference: 25.8 ± 22.8 events per hour) (p < 0.001). Importantly, there was a decrease in the percentage of non-rapid eye movement (NREM) 2 (p < 0.001), whereas NREM 3 and REM stages witnessed a significant increase (p = 0.001 and p < 0.001, respectively) after the surgery. CONCLUSION: The results of this study showed that weight loss after LSG yields improvement not only in AHI but also in many polysomnographic parameters such as sleep quality and desaturation indices.

Influence of obstructive sleep apnea on left ventricular mass and global function: sleep apnea and myocardial performance index.

Obstructive sleep apnea (OSA) is associated with cardiovascular mortality and morbidity. It may predispose patients to left ventricular hypertrophy and heart failure. The aim of this study was to determine the left ventricular mass (LVM) and myocardial performance index (MPI) reflecting left ventricular global function in uncomplicated OSA patients. Sixty-four subjects without hypertension, diabetes mellitus, and any cardiac or pulmonary disease referred for evaluation of OSA underwent overnight polysomnography and complete echocardiographic assessment. According to the apnea hypopnea index (AHI), subjects were divided into three groups: group 1, control subjects with nonapneic snorers (AHI < 5, n = 18); group 2, patients with mild to moderate OSA (AHI: 5-30, n = 25); and group 3, severe OSA (AHI > 30, n = 21). Basic echocardiographic measurements, LVM, and LVM index were measured. Left ventricular MPI was calculated as (isovolumic contraction time+isovolumic relaxation time)/aortic ejection time by Doppler echocardiography. There were no significant differences in age, sex, body mass index, heart rate, and systolic and diastolic blood pressure among the three groups. Left atrium, interventricular septum, left ventricular posterior wall, left ventricular end-diastolic and end-systolic diameters, LVM mass, and LVM index were not significantly different among the three groups. Left ventricular MPI was significantly higher in severe OSA patients (0.64 +/- 0.18) than in controls (0.49 +/- 0.18; P < 0.05). There was no significant difference between controls (0.49 +/- 0.18) and mild to moderate OSA (0.61 +/- 0.16; P = 0.08) and between mild to moderate OSA (0.61 +/- 0.16) and severe OSA (0.64 +/- 0.18; P = 0.84). The present study demonstrates that patients with severe OSA have global left ventricular dysfunction.

Observations on environmental asbestos exposure in a high risk area.

BACKGROUND AND OBJECTIVE: Environmental asbestos exposure is causally associated with various pulmonary pathologies. In Turkey, one of the most important sources of asbestos exposure is dust originating from the walls of homes whitewashed with white stucco. The main asbestos types implicated are tremolite and, to a lesser extent, chrysotile. This study investigated the presence and effect of environmental asbestos exposure in a small village in Isparta, Turkey. METHODS: Samples of asbestos mine ore, whitewashed plaster from the interior walls of the houses and whitesoil from the outside walls of the houses were analysed. Chest radiographs of 132 villagers aged 30 years and over and living in the village during the study were obtained. Verbal histories from the relatives of people who had died from lung cancer or mesothelioma and hospital records contributed 13 cases to the study population, giving a total of 145 cases under study. RESULTS: Chrysotile fibres were found in the old asbestos mine sample, and zeolite in the whitesoil sample from the outside walls. Abnormal CXR were found in 19 subjects (14. 4%), the most common being pleural calcifications and/or pleural plaques (n = 14, 10.6%). A further five subjects with pleural calcifications and/or pleural plaques were identified from verbal autopsy and hospital records. Malignant pleural mesothelioma was present in one living subject and four of the deaths. A possible familial clustering of lung cancer and malignant mesothelioma was noted. CONCLUSION: While tremolite asbestos is the asbestos found in most white soil in Turkey, in this village chrysotile asbestos was found in the white soil. Familial clustering may indicate genetic susceptibility or increased environmental exposure in some families.

Habitual snoring in primary school children: prevalence and association with sleep-related disorders and school performance.

OBJECTIVES: To determine the prevalence of habitual snoring (HS) and its association with both day- and nighttime symptoms, school performance and behavioral disturbances in a sample of primary school children. SUBJECTS AND METHODS: A cross-sectional study was performed on 1,605 children (819 boys and 786 girls) aged 7-13 years from 9 randomly selected primary schools located within the city limits of Isparta, Turkey. HS and sleep problems were assessed using a 55-item multiple-choice questionnaire. RESULTS: Of the 1,605 questionnaires, 1,164 were fully completed and returned, giving a response rate of 72.5%. The overall prevalence of snoring was 38.9%, while HS accounted for 3.5%. The prevalence of HS among boys (25, 3.0%) was higher than among girls (16, 2.0%; chi(2) for trend: p < 0.001, OR: 1.92, 95% CI: 1.01-3.66). There was an association between younger age and HS, as children aged 7-8 years had the highest prevalence (chi(2) for trend: 0.054, OR: 1.85, 95% CI: 0.81-4.22). Habitual snorers had more daytime and nighttime symptoms. Allergic symptoms, daytime mouth breathing, shaking the child for apnea, restless sleep and hyperactivity were significant and independent risk factors and sleep-related symptoms for HS. A significant and independent association was found between poor school performance and hyperactivity, nocturnal enuresis, tooth grinding and low parental/maternal education in multivariate analysis. CONCLUSION: Children with HS were more likely to have sleep-related daytime and nighttime symptoms. No significant associ- ation was determined between HS and poor school performance.

Immunization status in chronic obstructive pulmonary disease: A multicenter study from Turkey.

OBJECTIVE: The purpose of this study is to detect the prevalence and the factors associated with influenza and pneumococcal vaccination and outcomes of vaccination during 2013-2014 season in patients with chronic obstructive pulmonary disease (COPD) in Turkey. METHODS: This was a multicenter retrospective cohort study performed in 53 different centers in Turkey. RESULTS: During the study period, 4968 patients were included. COPD was staged as GOLD 1-2-3-4 in 9.0%, 42.8%, 35.0%, and 13.2% of the patients, respectively. Influenza vaccination rate in the previous year was 37.9%; and pneumococcus vaccination rate, at least once during in a life time, was 13.3%. Patients with older age, higher level of education, more severe COPD, and comorbidities, ex-smokers, and patients residing in urban areas had higher rates of influenza vaccination. Multivariate logistic regression analysis showed that advanced age, higher education levels, presence of comorbidities, higher COPD stages, and exacerbation rates were associated with both influenza and pneumococcal vaccination. The number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was 2.73 ± 2.85 and 0.92 ± 1.58 per year, respectively. Patients with older age, lower education levels, more severe COPD, comorbid diseases, and lower body mass index and patients who are male and are residing in rural areas and vaccinated for influenza had significantly higher rates of COPD exacerbation. CONCLUSIONS: The rates of influenza and pneumococcal vaccination in COPD patients were quite low, and the number of annual physician/outpatient visits and hospitalizations due to COPD exacerbation was high in Turkey. Advanced age, higher education levels, comorbidities, and higher COPD stages were associated with both influenza and pneumococcal vaccination.
