Objective: To evaluate the patients’ attitudes about the devices, of which they use for long-term respiratory support at home. Method: 200 consecutive patients were questioned about the treatment and devices of respiratory support at home by face to face questionnaire. Their records were taken from the archives of Social Security Agency. Results: 123 (61.5%) of the patients were men and 77 (38.5%) were women. The mean age was 65.8 ± 11.9 (15-92) years. The most frequently prescribed device was oxygen concentrator and BIPAP was the one that follows. The most common indications were hypoxic and hypercapnic respiratory failure due to COPD. The devices were prescribed by the state university hospitals, most commonly. The average daily oxygen usage duration was 16.3 ± 3.1 hours, the average duration was 7.4 ± 3.1 hours, for BIPAP. Twenty one (11.4%) of the patients, who were treated with LTOT, stated that they were taking oxygen less than 15 hours a day. Higher education levels of the patients was correlated with the higher rates of visiting the companies - that they bought the devices- both for information about and control of the devices (p=0.002). The rate of visiting companies/firms was significantly higher in patients, who use BIPAP and respiratory support combined with it (p=0.010). Twenty three (47.9%) of the 48 patients, who notified that their devices were impaired, waited for repairment by the firm, 20 (41.6%) investigated special repair facilities and the rest (10.5%) rented a new device. Conclusion: Effective and continuous technical maintenance support must be provided to the patients, who are treated with long-term respiratory support at home.

The pathophysiology of upper-airway obstruction (UAO) is complex. Possible causes of UAO that may lead to acute respiratory failure, are as follows: infections like acute epiglottitis and croup, obstructing tumors in the base of the tongue, larynx or hypopharynx, aspirated food or liquid contents, obesity and anatomical variations. Management changes according to the pathogenesis of the disorder. In patients with severe carbon dioxide retention or apnea, emergency endotracheal intubation must be carried out. Hereby, we describe a 23-year-old patient with susceptible upper-airway anatomy and UAO occurred following an upper respiratory infection and complicated with pulmonary hypertension and pulmonary edema. Our patient seems to be one of the complicated UAO cases, with an unusual but critical clinical presentation, evaluated in a wide spectrum and nicely returned to life.

This prospective study was designed to evaluate the effects of hyperthyroidism on flow-volume loops in nonasthmatic 20 patients with hyperthyroidism. Thyroid related hormones (Total T3, Total T4 and TSH), thyroid gland volumes with ultrasonography, circumference of neck values and flow-volume loops were obtained at the beginning and after three months of antithyroid treatment. Propylthiouracil treatment was followed by a statistically significant decrease in thyroid gland volume and circumference of neck (p0.001 and p0.001, respectively). The most significant result was improvement of maximum midexpiratory flow rate (MMEFR) after propylthiouracil therapy for three months (p= 0.003). Increases in mean forced expiratory flow after 25% of FVC has been exhaled (FEF25), mean forced expiratory flow after 75% of FVC has been exhaled (FEF75) values were found consistent with the overall improvement in expiratory flow parameters (p= 0.044, p= 0.012 respectively). In conclusion, we speculated that improvement of expiratory flow parameters might be the earlier changes in flow volume loops of patients who were treated with propylthiouracil for hyperthyroidism.

There are many studies supporting the family history in lung cancer. In this study, we observed 1500 with lung cancer cases diagnosed between the years 1995-2000 in our clinic, and investigated family tendency of lung cancer in a control group including partners of 600 patients with family history of cancer. We conducted face-to-face interviews with 100 patients with lung cancer, and with first degree relatives of the other 1400 patients with lung cancer. There were 600 positive family history of cancer. Control populations were matches of the cancer patients with positive family history of cancer. Cases and controls were asked to report on their family history of cancer, as well as smoking status of family members. In conclusion, in 40% of 1500 patients with lung cancer, there was positive family history of lung cancer with regard to malignity. This positive family history of cancer was consisted of 51.8% lung cancer, 35.5% digestive cancer and 12.7% other cancers such as breast, larynx, prostate and bone. In control group, the value of the positive family history of lung cancer with regard to malignity was 5.0% (p0.001). These results support the hypothesis of a genetic susceptibility by showing that the patients with lung cancer have significantly more positive family history of lung cancer and digestive cancer.

This study was designed to evaluate the effects of furniture production, mainly including fir tree (aberia mulleriana), on respiratory health of young workers and to compare the results with those obtained from previous studies. Sixty-four furniture-decoration students (57 males and 7 females) and 62 controls (54 male, 8 female) from different departments in the same school were included into the study. All participants were assessed with a questionnaire (concerning history of occupational exposure, work-related respiratory and other symptoms, smoking history, previous asthma history), full physical examination, spirometric evaluation and chest radiograph. Participants then performed serial monitoring of peak expiratory flow rates (PEFR) at work and away from work within a month. Mean age of students was 20.9 +/- 3.7 years, 20.5 +/- 2.6 years in controls. There was no difference between study and control groups with regard to age, gender, smoking status and previous asthma history. Reported cough (23.4 % vs. 8.1 %) and shortness of breath (18.8 % vs. 6.5 %) were significantly higher in furniture-decoration students than in controls (p = 0.016 and p = 0.034, respectively). Furniture-decoration students had higher conjunctivitis (34.4 % vs. 9.7 %, p = 0.001) and rhinitis (34.4 % vs. 19.4 %, p = 0.044) history when compared with controls. Both students and controls were normal in terms of respiratory examination. PEF recordings were performed for approximately one month. Diurnal variability greater than 20 % was seen in 12/64 (18.7 %) of students at work, whereas it was detected in 4/62 (6.4 %) of controls (p = 0.034). When comparing for the presence of diurnal variability greater than 20 % in weekends, no difference was found between groups (p = 0.457). In conclusion, early detection of work-related respiratory changes by serial monitoring of peak expiratory flows should save the workers from hazardous respiratory effects of the furniture production, especially in young population.

Sarcoidosis is a systemic granulomatous disease that primarily affects the lung and lymphatic systems of the body. The lungs are affected in over 90% of sarcoid patients. Although paranchymal lung disease is more common, the airways may also be involved. Bronchial mucosa is often affected in sarcoidosis, but endobronchial mass lesions are very rare. We present a case with multiple endobronchial mass lesions due to sarcoidosis.
