[Gamma knife for hypersecreting pituitary adenoma: analysis of 120 cases].

OBJECTIVE: To estimate the efficacy of Gamma knife radiosurgery (GKR) especially as a primary surgical treatment for hypersecreting pituitary adenoma. METHODS: One hundred and twenty cases with hypersecreting pituitary adenoma had been treated by Gamma knife radiosurgery. The clinical date had been analysed retrospectively. The tumor margin was covered by an isodose ranging from 45% to 70%. The margin dose was 15 to 32 Gy (mean 28.5 Gy) and the maximum dose varied from 35 to 70 Gy (mean 45.5 Gy). The total number of isocenter was 165 (mean 1-3). RESULTS: One hundred and eleven cases had been followed-up by hormone level, and 104 cases had been followed-up by image of MRI. The mean follow-up duration was 12-72 months (mean 36 months). The control rate of hormone level was 48.6%, the control rate of tumor growth was 96.2%, the incidence of hypopituitarism was in 2.7% and the incidence of tumor apoplexy was in 0.9% in followed-up cases. CONCLUSIONS: As a primary surgical treatment for hypersecreting pituitary adenoma, GKR can be effective and safe in controlling tumor growth and inducing hormonal normalization.

[An epidemic outbreak of respiratory infection caused by Chlamydia pneumoniae in medical workers].

OBJECTIVE: To investigate the clinical manifestations and the chest imaging characteristics of an epidemic outbreak of respiratory infection caused by Chlamydia pneumoniae (CP). METHODS: A prospective study for CP infection in 15 patients from September 2003 was carried out. Sputum and throat swab specimen were obtained and CP DNA was detected by polymerase chain reaction (PCR). Serum samples were obtained and immunoglobulin G and M (IgG and IgM) of antibodies to CP. pneumoniae were studied by microimmunofluorescence test. Chest X-ray and computed tomography were retrospectively analyzed. RESULTS: All patients presented fever, headache, sore throat, hoarseness, muscular ache, and dry cough. Acute cough was often associated with chest pain. The sputum blood was present in 3 patients (20%). Moist rales were heard in 4 patients. Chest imaging abnormalities were present in 67% (10 patients). The organism was demonstrated in 87% (13 patients) by PCR. The most common imaging abnormalities were unilateral and (or) bilateral multi-focal or solitary alveolar nodular opacities (9 patients). The patchy shadows were found in 2 patients, and pulmonary consolidation associated with the local pulmonary edema in 1 patient. Hilar or mediastinal lymphadenopathy and pleural effusion was not found. CONCLUSIONS: The colony occurrences and similar clinical and chest imaging manifestations are characteristics of an outbreak of respiratory infection caused by CP in medical workers. An outbreak of respiratory infection caused by CP should be differentiated from severe acute respiratory syndrome (SARS).
