[Role of surgical procedures in the diagnosis and therapy of tuberculosis].

Over the last decades the annual number of surgical intervention for treatment of pulmonary tuberculosis has steadily declined. Despite effective antituberculotic medication, there are still indications for thoracic surgery. The aim of the present study was to give an account of the diagnostic and therapeutic role of surgery of pulmonary tuberculosis. Therefore we analysed all operated patients with pulmonary tuberculosis between 1988 and 1999. In 2% of all patients with pulmonary tuberculosis surgical intervention was performed (n = 35). Their main indication was resection for suspected carcinoma, multi-drug resistance or non-compliance to the medical treatment, decortication because of cavern rupture or empyema, hemoptoe and destroyed lung. A additional indication for surgery was pulmonary aspergilloma caused by superinfection of postspecific cavities. Postoperative complications like bleeding (> 1000 ml) or broncho-pleural fistula occurred in 37%, none of the patients died. Surgery is still a valid option für the treatment of pulmonary tuberculosis. Before surgical intervention, a long term antituberculotic chemotherapy is essential. Patients have to be selected individually because of an increased morbidity. In 10% of all operated patients (n = 1132) with preoperative unidentifiable pulmonary mass the infiltrate was specific aetiology.

[Incidence of resistance and risk factors for resistance in Mycobacterium tuberculosis. A retrospective study of 1,055 patients of a specialty hospital 1984 to 1993].

For the past decade, there have been no data on the time course of drug-resistant tuberculosis and on risk factors for drug resistance in former West Germany. We reviewed the medical records of all patients with positive cultures for Mycobacterium tuberculosis from 1984 until 1993 in a hospital near Hamburg. Drug-susceptibility testing was performed for isoniazid, rifampicin, ethambutol, and streptomycin, using the modified proportion method. Of 1,055 patient, 9.6% had isolates resistant to one or more drugs. Of the isolates, 5.8% showed resistance to isoniazid or rifampicin and 1.8% to both isoniazid and rifampicin. There was no significant change of the resistance rate during the study period. Twenty six percent of 89 patients from South America, Africa or Asia had isolates resistant to one or more drugs, compared with 7.6% of 799 patients born in Germany (odds ratio (OR) 4.2; 95% confidence interval (95% CI) 2.5-7.3). Among patients born in Germany, 32% of 101 patients with a history of prior antituberculosis drug therapy had resistant organisms, versus 4.2% of 698 patients without prior therapy (OR 10.7; 95% CI 6.1-18.7). Resistance orates for 35 patients, who had been treated within the last 5 yrs, and for 65 patients, who had been treated more than 5 yrs ago, were 57 and 17%, respectively (OR 6.6; 95% CI 2.9-16.6). Our results suggest that there is no increase in the proportion of drug-resistant tuberculosis in our hospital, and that patients with a recent history of antituberculosis drug therapy and patients from South America, Africa, or Asia are at high risk for drug resistance.

Drug-resistant tuberculosis in northern Germany: a retrospective hospital-based study of 1,055 patients from 1984 until 1993.

[Memento intestinal tuberculosis].

We report the history, symptoms and diagnostic procedures of eight patients (four female, four male; mean age 44.5 years) with abdominal tuberculosis. In all cases differential diagnosis was complicated by an inadequate interpretation of chest X-rays. Only two patients were immigrants. Chemotherapy of tuberculosis was successful in seven patients, one 65-year old female with miliary tuberculosis and ileus died.
