[Comparative analysis of the semiotics of disseminated pulmonary tuberculosis and exogenous allergic alveolitis in accordance with the data of computed tomography].

Objective: to improve the differential diagnosis of disseminated pulmonary tuberculosis (DPT) and exogenous allergic alveolitis (EAA) via comparative investigation of their computed tomography (CT) semiotics and identification of the most informative diagnostic criteria.

Material And Methods: 70 patients, including 40 patients with DPT in a phase of infiltration and 30 patients with acute EAA, were studied using a Somatom Emotion 16 multi-slice spiral CT scanner (Siemens). All the patients underwent spiral scanning from the upper chest aperture to the costodiaphragmatic recesses with a high CT algorithm at 0.

[The radiation therapy of skin cancer of the face].

Results of three-year radiotherapy are assessed in 586 patients with skin cancer, with tumors localized on the skin of the face in 484 of these. The results of treatment were found to depend on the histological structure of the tumor and disease stage: 100% cure was attained in patients with basal-cell carcinomas and T1 stage, whereas only 7% of patients with T4 stage were cured; in patients with squamous-cell carcinoma these figures were, respectively, 96.2 and 10%.

[Probit analysis in assessing the results of radiation therapy of disseminated cancer of the tongue and floor of the mouth].

The results of radiation therapy were compared in 217 patients at advanced stages of cancer of the tongue (131) and fundus of the mouth (86) using split courses of conventional (SCF) and dynamic fractionation (SDF) and SDF combined with metronidazole. Dose-effect curves were evaluated by probit-analysis. SCF at a total focal dose increased from 64-76 up to 78-82 Gy did not improve therapeutic results.

[Radiotherapy, using metronidazole, of regional lymph node metastases of cancer of the oral mucosa].

Altogether 67 patients with oral mucosa cancer metastases to the regional lymph nodes were given a split course of gamma-beam therapy with traditional dose fractionation and dynamic fractionation. Radiotherapy in the presence of metronidazole radiosensitization was given to 40 patients. Metronidazole was administered per os 3 = 4 h before irradiation with fractions I, III and V of each phase of a split course.

[Radiation treatment with metronidazole in patients with oral mucosa cancer in the late stages].

Eighty patients with cancer of the oral mucosa at late stages were treated by a split course of gamma-beam therapy in two variants of dose fractionation as an independent therapeutic method. Metronidazole (at a summary dose of 30 g/m2) was given to 40 patients 3-4 h before irradiation. Short-term results of a 6-month-follow up have shown that radiation therapy with metronidazole improves the results.
