Standard antituberculous therapy including isoniazid, rifampin, ethambutol, and pyrazinamide is widely used for the treatment of active tuberculosis. Its most important side effect is hepatotoxicity, ranging from asymptomatic transaminitis to fulminant hepatic failure. A 19‐year‐old woman was admitted to our unit due to jaundice and unconsciousness. According to her past medical history, she was diagnosed as having extrapulmonary tuberculosis and had been prescribed standard antituberculous therapy. The patient became icteric and unconscious on the fourth day after therapy initiation. She was diagnosed with drug‐induced acute fulminant hepatic failure and underwent living‐related liver transplantation. Nonhepatotoxic antituberculous therapy (cycloserine, ciprofloxacin, streptomycin, and ethambutol) and low‐dose immunosuppressive therapy were started after transplantation. Currently the patient is very well with normal graft function 42 months after transplantation. Here we report a case of a patient with acute fulminant hepatic failure caused by isoniazid, rifampicin, or both, who was successfully treated with living‐related liver transplantation and a relatively less hepatotoxic antituberculous therapy. In conclusion, liver transplantation is a feasible therapy for individuals with standard antituberculous therapy–induced hepatic failure. Nonhepatotoxic antituberculous therapy may achieve control of active tuberculosis in such individuals after transplantation. Liver Transpl 12:1427–1430, 2006.

Abstract: Interferon alpha (IFN‐α) is an immunomodulator that is used as an antiviral agent in active chronic viral hepatitis C. IFN therapy can cause an induction or exacerbation of sarcoidosis. Although several reports in the gastroenterology literature have suggested an association between IFN therapy and sarcoidosis, this association has rarely been described elsewhere. A 47‐year‐old woman developed sarcoidosis after cessation of treatment with IFN and ribavirin for chronic hepatitis C. Her sarcoidosis showed liver, pulmonary and skin involvement. She continues to be monitored regularly in the Department of Pulmonary Diseases without steroid therapy. Her sarcoidosis improved spontaneously. We conclude that patients should be monitored for sarcoidosis during and after IFN therapy.

Pulmonary artery aneurysms due to Behçet’s disease are mainly seen in young males and very rarely in females. To our knowledge there are only 10 cases reported in the related literature. Emergent transcatheter embolization was performed in a female patient with a known history of Behçet’s disease in whom massive hemoptysis developed because of rupture of a giant pulmonary artery aneurysm. At 6-month follow-up, transformation of the aneurysm sac into an air cavity was detected. To our knowledge, such a transformation has never been reported in the literature before. Embolization of the pulmonary artery aneurysm and the mechanism of cavity transformation are reviewed and discussed.

Purpose: To evaluate ocular involvement in patients with sarcoidosis. Methods: The prevalence of ocular manifestations was studied in 139 Turkish patients with sarcoidosis as a cross section. Color photography and fluorescein angiography were performed on patients suspected of having ocular involvement. Results: Ocular involvement was seen in 12.9% patients. Of 18 patients with ocular sarcoidosis, 39% had anterior and posterior involvement, 28% only anterior, 11% only posterior, 16.7% conjuctival, and 5.6% eyelid involvement. There was no statistically significant relationship between radiological grading and ocular involvement. Conclusions: The most common ocular involvement in this study was both anterior and posterior segment involvement.

It was aimed to evaluate KL-6 glycoprotein levels to determine if it may be a diagnostic marker for the connective tissue diseases (CTDs) predicting CTD-related interstitial lung diseases (ILDs) (CTD-ILD) development and to examine if there was a difference between patients and healthy controls. The study included 113 patients with CTD (45 CTD without lung involvement, 68 CTD-ILD) and 45 healthy control subjects. KL-6 glycoprotein levels were analyzed with ELISA in patients and the control group. The relationship between KL-6 glycoprotein levels and CTD-ILD was assessed. In the comparison of all the groups in the study, significantly higher levels of KL-6 were determined in the CTD-ILD group than in either the CTD without pulmonary involvement group or the healthy control group (p < 0.008 and p < 0.001, respectively). There was no statistically significant difference between the KL-6 levels in the healthy control group and the CTD without pulmonary involvement group (p = 0.289). The KL-6 levels did not differ significantly according to the connective tissue diseases in the diagnostic groups (systemic lupus erythematosus, Sjögren’s syndrome, rheumatoid arthritis, mixed connective tissue disease, scleroderma, polymyositis/ dermatomyositis). In the healthy control group, there was a statistically significant difference between KL-6 levels in smokers and non-smokers. Smokers had significantly higher serum KL-6 levels compared with non-smokers (p < 0.05). There was no statistically significant difference between smoking status (pack-year) and serum KL-6 levels. There was no statistically significant correlation between serum KL-6 levels and time since diagnosis of CTD and CTD-ILD. The level of KL-6 as a predictive factor could be used to identify the clinical development of ILD before it is detected on imaging modality. Further prospective clinical studies are needed to define whether levels of KL-6 might have prognostic value or might predict progressive ILD.

Aims and background Many prognostic factors have been evaluated both for SCLC and NSCLC. The prognostic significance of blood group antigen expression of tumor tissues has been studied particularly in NSCLC, yielding divergent results. The aim of the present study was to investigate the prognostic value of the tumoral expression of blood group antigens ABH in lung cancer. Methods The presence of blood group antigens was assessed immunohistochemically in paraffin-embedded tumor samples from 92 patients diagnosed between 1996 and 1997. Monoclonal antibodies were used to detect blood group antigens. Results The median survival was longer in NSCLC patients whose tumors were positive for blood group antigen A (P = 0.009). Since the expression of blood group antigen A in tumor cells was limited to patients with type A or AB blood, survival analysis of these patients showed survival to be longer in non-small cell lung cancer patients with blood group antigen A-positive tumors (P = 0.0019). Conclusions Expression of blood group antigen A in tumor cells is an important, favorable prognostic factor in patients with non-small cell lung cancer, which could be useful to stratify patients with blood group A or AB according to possible outcome, and to guide therapeutic decision-making. The expression of blood group antigens ABH should be evaluated in larger series of lung cancer patients (including small and non-small cell lung cancer) with all blood types.

Aim. This study aimed to assess the long-term respiratory effects of tear gases among the subjects with history of frequent exposure. Materials and Methods. A questionnaire by NIOSH and pulmonary function tests was performed in 93 males exposed to the tear gases frequently and 55 nonexposed subjects. Results. The mean numbers of total exposure and last 2 years exposure were 8.4 ± 6.4 times, 5.6 ± 5.8 times, respectively. Tear gas exposed subjects were presented with a higher rate for cough and phlegm more than 3 months (24.7% versus 11.3%, P > 0.05). Mean FEV1/FVC and % predicted MMFR in smoker exposed subjects are significantly lower than those in smoker controls (81.7% versus 84.1%, P = 0.046 and 89.9% versus 109.6%, P = 0.0004, resp.). % predicted MMFR in nonsmoker exposed subjects is significantly lower than that in nonsmoker controls (99.4% versus 113.1%, P = 0.05). Odds ratios for chest tightness, exercise dyspnea, dyspnea on level ground, winter morning cough, phlegm, and daily phlegm were increased almost 2 to 2.5 folds among tear gas exposed subjects. Conclusion. The rates for respiratory complaints were high in the case of the exposure to the tear gases previously. Tears gas exposed subjects were found to be under the risk for chronic bronchitis.

Background Sarcoidosis is a multisystemic disease of unknown etiology. The presentation and frequency of different organ involvement can vary according to race, geographical location and gender. Because of the multiorgan involvement and its mimicking nature, the diagnosis is usually a challenge, even to specialists. Therefore, knowledge of the epidemiologic features of the disease is important. Methods The first case report of sarcoidosis in Turkey was published in 1954. We obtained data from case series by hand searching of journals and congress abstract books on pulmonary medicine between 1954 and 2000. Series of 5 or more cases were included in our compilation of data. Results Data for 1327 patients with the diagnosis of sarcoidosis were obtained from 29 reports. There were nearly twice as many females as males with the disease in these case series. Most of the patients were at stage 1 or 2 at the time of diagnosis. Peripheral lymph node enlargement was reported in 119 patients, skin involvement in 22 and nervous system involvement in 12 patients. Erythema nodosum was reported in 137 patients. Serum angiotensin-converting enzyme was elevated in 52% and the tuberculin skin test was positive in 24% of patients. Organ biopsies seemed to be the preferred diagnostic method in the initial papers while recent papers revealed the value of obtaining a bronchoscope biopsy. Conclusion Despite several limitations of our study, this is the first compilation of 46 years of data on sarcoidosis in Turkey. Further studies on the geographical distribution and incidence and prevalence are needed for our country.

A 34-year-old man was admitted with dyspnea, cough, and fever. Thorax computed tomography revealed ground glass opacities and pneumomediastinum. The patient was diagnosed as amyopathic dermatomyositis due to skin lesions and radiological findings. Despite immunosuppressive treatment clinical deterioration and radiological progression were observed and the patient died because of severe hypoxemic respiratory failure. The patient presented with extremely rare occurrence of pneumomediastinum and subcutaneous emphysema in amyopathic dermatomyositis with a poor prognosis.
