[Ecological aspects of American cutaneous leishmaniasis. 9. Prevalence/incidence of the human infection in the municipality of Pedro de Toledo and Miracatu, São Paulo, Brazil]. / Aspectos ecológicos da leishmaniose tegumentar americana 9. Prevalência/incidência da infecção humana nos municípios de Pedro de Toledo e Miracatu, São Paulo, Brasil.

The epidemiologic study was conducted during the 1973-1984 period. The clinical prospective exam and Montenegro skin, immunofluorescent and passive hemagglutination tests have been carried out in three small localities between Pedro de Toledo e Miracatu municipalities, São Paulo, Brazil. The retrospective study of human-cases involved 108 and 65 cases registered in Pedro de Toledo e Miracatu, respectively. In the three communities studied, 273 people were examined clinically and serologically. Twenty two individuals had had signals of cutaneous leishmaniasis; 10.2 and 12.8% were seropositive to IF and HA. Leishmanin skin testing of a sample of 154 people residents in Pedra do Largo showed prevalence of Leishmania infection in 25.5%. This result involved individual of all ages and sex. However, 5.8% of them were from 0 to 9 years old. The data confirmed that active parasite transmission didn't occur every year, either. The human infection seems not to depend on man contact with a forest. The incidence relatively low suggests low endemic area for cutaneous leishmaniasis and an explosive behavior of the cases. The temporal distribution of disease was irregular and the epidemiological pattern seen was different from the other endemic area of South America.

Percutaneous transluminal angioplasty of the hepatic veins for treatment of Budd-Chiari syndrome.

The authors report a case of Budd-Chiari syndrome caused by occlusion of all of the hepatic veins which was treated by percutaneous transluminal angioplasty. There were two recurrences requiring redilatation. Two years later, the patient was asymptomatic and off medication.

Angiography in primary myomas of the alimentary tract.

Fifteen cases of smooth muscle tumor of the alimentary tract were collected for analysis from several institutions. The findings showed that angiography is the best method available for diagnosis and evaluation of such tumors but is unable to differentiate benign from malignant lesions unless arterial invasion is detected. Computer tomography, ultrasound, and angiography are compared in the diagnosis of one case. Additionally, the angiographic pattern of a leiomyoblastoma is presented, presumably for the first time.

Angiography in cystadenoma and cystadenocarcinoma of the pancreas.

The angiographic findings 9 surgically proved cases of primary cystic neoplasms of the pancreas are reported. Angiography demonstrates the extent and origin of the tumour and permits in many cases a differentiation between benign and malignant lesions.

Radiographic diagnosis of shallow gastric ulcers: a comparative study of technique.

The double-contrast method, mucosal-relief study and compression technique associated with pharmacological hypotonia were retrospectively compared for accuracy in diagnosing 13 proved cases of shallow gastric ulcers. The double-contrast method was significantly more accurate than the other two.

Value of the compressive technique associated with pharmacological hypotonia in the diagnosis of erosive gastritis.

The double-contrast method and the compressive technique associated with pharmacological hypotonia of the stomach were compared in 13 cases and found to be equally valuable in the diagnosis of erosive gastritis.
