[Broncho-mediastinal fistula -- a rare manifestation of a tumor].

Broncho-mediastinal fistulaes are a very rare condition, existing only a report of a case related with primary lung cancer. The authors present a clinical case of a white 58-year-old man, with previous history of cigarette smoking and diabetes, with fever, productive cough and progressive dyspnea, with radiological evidence of right inferior lobar pneumonia. We noticed a radiological deterioration, despite the high spectrum antibiotic therapy, so he was submitted to thoracic computerized tomography and broncofibroscopy, which revealed extensive infiltration of the principal and intermediary bronchioles with a broncho-mediastinal-esophagic fistula. The histological exam revealed a pavimentam cellular carcinoma.

Analysis of Q fever in Uruguay.

The first outbreak of Q fever in Uruguay occurred in 1956. The infection, which is caused by Coxiella burnetti, occurs in sheep, cattle, swine, and horses, but not in fowl or guinea pig. Most of the cases studied have been traced to cattle. Fourteen outbreaks of this disease were studied between 1975 and 1985. All of the 1,358 clinically suspected cases (814 serologically confirmed) reported in Uruguay occurred in workers at meat-processing plants. Diagnoses of cases and serologic surveys were made by use of complement fixation, capillary agglutination, and layer microagglutination techniques.

[Neuroimaging features associated with AIDS].

Due to the nonspecific clinical presentation of Central Nervous System disorders that may come out during the course of Human Immunodeficiency Virus infection, we emphasize the importance of neuroimaging on the differential diagnosis of these situations. Review and illustration of the most typical imaging patterns of the main Central Nervous System disorders in Acquired Immunodeficiency Syndrome.

[Craniopharyngiomas. Clinicopathological aspects in different age groups].

Craniopharyngiomas are rare brain tumors of the hypothalamo-pituitary region, developing from embryonic remnants of Rathke's pouch and sac. Their overall incidence is 0.13 per 100,000 person years. Most frequently, they are suprasellar, start growing in childhood and originate neurological and hormonal symptoms. We retrospectively studied patients treated in our institution for craniopharyngioma in the last 10 years, in order to evaluate their clinical, imaging and pathological characteristics. Of the 32 patients analysed, 18 were females and 14 males with ages ranging between 6 and 81 years (early onset group--EOG aged 5-14 years: 7 patients; middle age onset group--MAOG aged 15-49 years: 15 patients; late age onset group--LOG aged > or = 50 years: 10 patients). Visual impairment was the most frequent presenting clinical feature in EOG (71.4%) and MAOG (86.6%), while in the LOG personality and cognitive changes including memory loss predominated (60%). Headaches were very frequent in all groups (EOG 42.8%, MAOG 60%, LOG 40%). Meningitis and seizures were presenting features, each in one patient. Regarding endocrine symptoms and signs, growth failure was present in 57.2% of the EOG. Amenorrhea was present in 5 of 10 female patients of the MAOG. Preoperatively, TSH was deficient in 25%, ACTH in 15.6% and gonadotropin in 25% of the patients. There were no cases of diabetes insipidus. Preoperative CT and MR revealed a calcified mass in 12 (37.5%), a partially cystic mass in 20 (62.5%) and a lesion involving or extending into the third ventricle in 7 (21.9%) patients. Twenty seven (84.4%) patients were treated primarily by surgery. In 4 (12.5%) cases the tumour was considered inoperable and 1 (3.1%) patient refused surgery; all were in the LOG. Surgical approach was transsphenoidal in 2/27 (7.4%) (all of them in the LAOG) and by craniotomy in the others. The tumour removable was considered complete in 10 (37%--EOG 2/7, MAOG 6/15, LOG 2/5) and subtotal in 17 (62.9%) patients. Eight (29.6%) patients were reoperated for recurrent tumour. Postoperative radiotherapy was administered in 12 cases with residual tumor, and 3 inoperable tumors were treated primarily by conventional external radiotherapy. Pathological study revealed the adamantinomatous type in 25 (92.6%) and the papillary type in 2 (7.4%--all men in the MAOG) tumors. The average follow-up was longer in the EOG (82.6 +/- 40.7 months) than in MAOG (57.2 +/- 48.5 months) and in LOG (48 +/- 92 months). Four (12.5%) patients died, 1 during the follow-up period due to a radiation-induced astrocytoma and 3 in the postoperative period because of cerebral hemorrhage and hydrocephalus (1 in the EOG and 2 in the LOG). In summary, we found the clinical presentation to be different in the 3 age groups, with a large number of patients in the MAOG. In this group were the only examples of the papillary form. Better prognosis was associated with a total resection at initial surgery.

Outcomes of the first Family Practice Chief Resident Leadership Conference.

In June 1989 the first Family Practice Chief Resident Leadership Conference was presented to 27 Texas second-year residents who had been selected to serve as chief residents during their third year. The objectives of the conference were to assist these emerging leaders to develop better stress management and leadership skills and to strengthen their ties with the Texas Academy of Family Physicians. The conference featured two major workshops on stress management and leadership skills, and included plenary speeches and large and small group discussions. This article reports the outcomes of the conference as measured by the evaluation instrument completed by participants. Analysis of the results indicated that the conference had a positive effect on the residents.
