Bronchobiliary Fistula Due To Hydatid Disease of the Liver
(Acta Medical Belgica, 2002) Uzun, K; Özbay, B; Etlik, Ö; Kotan, Ç; Gencer, M; Sakarya, ME
As a complication of hydatid cyst disease of the liver, bronchobiliary fistula is a rare condition and manifests as bilioptysis. We report the case of a 34 year-old man with echinococcosis of the liver who developed a bronchobiliary fistula which manifested as chronic cough and bile stained sputum. A chest X-ray showed an unilateral infiltrate in the costodiaphragmatic angle. Bronchoscopy revealed bile filling the right basal bronchi. Magnetic resonance cystography revealed that the hepatic bile ducts communicated with the right basal pleural space. Percutaneous transhepatic drainage was applied. When the patient was reevaluated, the hydatid cyst had eroded into the pleural space, and a pleural effusion had developed. The condition of the patient deteriorated. Hence, surgical therapy was performed. After surgery, the condition of the patient improved. He was discharged from the hospital in good condition.
Effects of Cigarette Smoking on the Circadian Rhythm of Heart Rate Variability
(Taylor & Francis Ltd, 2000) Eryonucu, B; Bilge, M; Güler, N; Uzun, K; Gencer, M
Background - The effects of cigarette smoking on the circadian rhythm of heart rate variability (HRV) are not known. Methods - We studied the effects of cigarette smelting on the circadian rhythm of HRV in 24 smoking and 21 non-smelting healthy subjects. Twenty-four hour ambulatory electrocardiograms were recorded and ti me domain parameters of HRV (SDNN [standard deviation of all R-R intervals], SDANN [standard deviation of the averages of R-R intervals in all 5-minute segments of the entire recording], RMSSD [the square root of the mean of the sum of the squares of differences between adjacent R-R intervals]) were determined for the entire 24-hour period and for each 3-hour period. Results - In total, SDNN and SDANN were significantly lower in smokers than non-smokers (116 +/- 26 vs 136 +/- 27, P < 0.05 for SDNN, 109 +/- 25 vs 121 +/- 24, p < 0.05 for SDANN). However, there were no statistical differences between smokers and non-smokers in heart rate (81+/-9 vs 76 +/- 10, P > 0.05) and RMSSD (32 +/- 12 vs 37 +/- 18, P > 0.05). These HRV parameters showed a circadian variation: they increased at night and decreased during the day in both groups. The parameters were lower in smokers than non-smokers during daytime (especially, between 8-14 hours). However, no differences were detected during night-time. Conclusions - Time domain parameters of HRV (SDNN, SDANN and RMSSD) in both smelting and non-smoking healthy subjects have a circadian rhythm. SDNN and SDANN were lower in smokers than non-smelters during daytime.
Relapsing Polychondritis
(Karger, 1998) Özbay, B; Dilek, FH; Yalçinkaya, I; Gencer, M
In this article, we report on a 40-year-old man with relapsing polychondritis (RP) of the tracheobronchial tree without clinical manifestations of other systems including nasal septum and earlobe cartilage involvement. The illness was diagnosed histologically, and treatment with procaine penicillin was successful. RP is an unusual systemic disorder characterized by widespread inflammation and destruction of cartilage tissues. The main cause is usually autoimmune. In RP various clinical manifestations including nasal chondritis, arthritis, scleritis, damage to tracheal and bronchial cartilage, and aortic, cardiac, and renal involvement may occur. Isolated tracheobronchial involve ment is very rare. The diagnosis must be based on a combination of clinical and pathologic features. If diagnosed early, appropriate treatment may prevent life-threatening airway obstruction.
