[Obstructive sleep apnea in shift workers].

UNLABELLED: The aim of the study was to compare intensity of sleep disordered breathing in standard nocturnal polisomnography (PSG) and diurnal PSG after night shift in shift workers with obstructive sleep apnea syndrome. METHODS: 25 shift workers (24 M, 1 F), aged 45,4 +/- 9,1 yrs, of mean BMI 31,9 +/- 4,02 kg/m2 were studied. Nocturnal PSG and diurnal PSG after night shift were performed in all participants. RESULTS: The mean apnea/hypopnea index (AHI) in diurnal PSG was higher than AHI in nocturnal PSG, 47,8+/- 27,4/h vs 38,0 +/-24,1/h respectively, (p<0,05). Not significant tendency towards higher oxygen desaturation index (ODI) in diurnal PSG was observed, 40,4 +/-25,5/h vs 31,9 +/-25,8/h respectively. CONCLUSION: The study demonstrated that there is a significant increase in AHI in diurnal PSG after night shift compared to standard night PSG in shift workers with OSAS. This may negatively influence diagnosis and treatment.

[Correlation between bronchoscopically visible aspects and histopathologic results in patients with suspected lung cancer].

The aim of our study was to determine correlation between bronchoscopically visible lesions and histopathologic classification and whether cytology and histopathology can complement each other in diagnosis of pulmonary neoplasm. Fibroptic flexible bronchoscopy was performed in 208 patients who where suspected of having lung cancer--abnormal chest x-ray or hemoptysis. Material for histopathologic examination was obtained from bronchial brushings, bronchial forceps biopsy and bronchial washings. Positive results were classified as non--small cell or small cell carcinomas. All patients were questioned about smoking history. In 165 patients there were visible signs of neoplasm in bronchoscopic examination: tumor, necrosis, infiltration, compression. Histopathology was positive in 90 cases:small cell carcinoma 32%, non-small cell carcinoma 68%. In 23 cases material for histopathologic examination was obtained from both bronchial brushings and foceps biopsies: results were compatible in 78%. Bronchial brushings identified neoplasm in three additional cases. In analysed group of 208 patients cancer cells were found in 43%. Examination of bronchial brushings coplements forceps biopsy in diagnosing and typing lung neoplasms and could be performed more frequently in patients undergoing fiberoptic bronchoscopy.
