Reviving an old idea: can artificial pneumothorax play a role in the modern management of tuberculosis?

OBJECTIVE: To determine the usefulness of artificial pneumothorax (AP) in the management of pulmonary tuberculosis (PTB) patients when anti-tuberculosis treatment is ineffective. DESIGN: We evaluated the outcome of therapy in 214 patients with cavitary PTB bacteriologically confirmed by culture treated during 1998-2004, 78.9% of whom had multidrug resistance. AP was applied in 109 patients (56 newly diagnosed TB and 53 retreatment cases). A control group consisted of 105 patients (respectively 55 and 50) treated without AP. The average period of AP application was 4.5 months for newly diagnosed patients and 9 months in retreatment cases. Anti-tuberculosis treatment regimens in both groups were based on drug susceptibility test results. RESULTS: Culture negativity was achieved in patients treated with AP in all new cases and in 81.1% of retreatment cases. Cavity closure occurred in 94.6% and 67.9% respectively. In the control group, culture negativity was achieved in respectively 70.9% and 40.0%, and cavity closure occurred in respectively 56.3% and 24.0%. CONCLUSION: AP considerably improved the treatment outcome in both newly diagnosed and retreatment patients. This procedure can be considered a useful addition in managing certain patients with cavitary TB, particularly those with drug resistance.

[Artificial pneumothorax in the treatment of destructive pulmonary tuberculosis complicated by its drug-resistant pathogen].

A hundred and nine patients with complicated destructive pulmonary tuberculosis who had received chemotherapy with reserve drugs, artificial pneumothorax (AP), pneumoperitoneum (PN), physiotherapy, and resection surgery were followed up. The application of video thoracoscopy made it possible to eliminate any types of pleural adhesions. Individualization of therapeutic measures considerably increases the efficiency of treatment. AP is the method of choice in therapy of newly detected patients who have undergone ineffective routine treatment regimens.

[Differential diagnosis of lobar (regional, segmental) extent pulmonary tuberculosis].

Two hundred and fifteen patients with pulmonary involvement of lobar (regional, segmental) extent were examined. The examination procedure included clinical and laboratory tests, X-ray tomographic study, and computed tomography, bronchoscopy with biopsy, cyto- and histological studies. The nosological diagnosis was established in 96.5% of cases. Differential diagnosis was found to be difficult in 3.5% of cases.

[Roentgenological diagnosis of silicotuberculosis].

Possibilities of roentgenologic method of examination with the use of roentgenography and tomography in the diagnosis of current forms of silicotuberculosis and tuberculosis in workers of the industries highly exposed to silicosis are analysed. ++Clinico-roentgenological+ pictures of 305 patients were studied in their dynamics for the period of 3 to 10 years. Being characterized by a benign course, silicotuberculosis is most often diagnosed in persons who left their work. A follow-up at least at 6-month intervals is of great importance in assessing its activity.

[Diagnosis of silicotuberculosis activity].

Possible determination of silicotuberculosis activity with various clinico-laboratory, roentgenological, biochemical and immunological procedures was analyzed by the materials on observation of patients with silicotuberculosis. The authors considered 117 observations relating to 88 male and 29 female patients aged 43 to 67 years. High informative capacity of the complex investigation including determination of gamma-globulin levels in blood serum, the albumin-globulin coefficient, the absolute count of lymphocytes and T-lymphocytes and lymphocyte migration inhibition in the test with tuberculin before and after the provocative tuberculin test was shown.

Surgical stimulation of the uveoscleral outflow. Experimental studies on enucleated human eyes.

Six series of experiments were performed on 45 isolated cadaver eyes. In the first series, the outflow facility of the human sclera was measured, in the others, five surgical techniques for stimulating the uveo-scleral outflow were evaluted with the help of a constant pressure perfusion technique. It was found that the scleral C-value was pressure independent and its average value was equal to 0.0036 mm3/min/mmHg per 1 cm2 (100 mm2) of scleral surface. After the implantation of a scleral strip into the supra-uveal space, the mean increase in the total C-value was 23% of its initial value, ranging from 7 to 35%. After cyclodialysis the C-value increment varied from 17% to 66%, averaging 30%. The average increase in the outflow facility amounted to 60% (range 24--96%) in those cases where implantation of the scleral strip in the suprauveal space was combined with cyclodialysis. After implantation of a scleral strip, combined with subscleral sinusotomy, the C-value increment varied from 18 to 71%, averaging 41%. After cyclodialysis combined with goniospasis, the mean increase in the outflow facility coefficient was 62% (range 43%--108%).
