Incidência e tratamento dos cistos.

The records of 78 patients (1978-1987 period) submitted to surgical treatment of cysts, were analysed to verify the cyst location, etiology, types of cysts, and surgical techniques. There were made commentaries and orientations on the necessity of radiography, cytological and histopathological examination and post-operative radiological control.

Tratamento endurecedor para cones de guta-percha.

The subject of this work was to study a hardening procedure for gutta-percha points, in order to make ease their introduction in very curved root canals. Gutta-percha points of different brands and dimensions were submitted to treatment with alcohol 96 degrees for 1 to 3 days. After this treatment the weight necessary to make a bending of 35 degrees on the tip of the gutta-percha was evaluated. The obtained results were submitted to statistic analysis and the following conclusions can be observed: a. The treatment with alcohol make hard the gutta-percha points in a significant level. b. There was not significant differences between the results obtained with more than one day of alcohol treatment. c. The treatment with alcohol do not make hard all the brands of gutta-percha points.

Implicações nutricionais no tratamento e recuperação de pacientes adultos com diarréia crônica.

The nutritional assessment by 24 hour-dietary recall, anthropometry and blood-components measurements was undertaken in 23 adult patients, 17 males and 6 females suffering of chronic diarrhea from pancreatitis (30%), inflammatory bowel disease (22%), short intestine syndrome (9%) and unknown diarrhea (35%). The nutritional assessment was done at the entry and repeated at the discharge of the hospitalization that averaged 35 days, during which the patients received specific medical treatment along with obstipating diets. The hospitalization resulted in overall improvement of the patients either clinically by reducing their defecation rate or nutritionally by increasing their protein-energy intake and the values of anthropometry and blood components (albumin, free-tryptophan and lymphocytes). When the patients where divided into two groups based on their fecal-fat output one could note the better nutritional response of the group showing steatorrhea than the non-steatorrhea group, with the serum albumin and the arm-muscle circumference being discriminatory between groups. However even in the better recovered patients the indicative values of a satisfactory nutritional status were not accomplished. Thus, these data suggest that besides the overall nutritional improvement seen in the studied chronic diarrhea patients the full-nutrition recovering would demand either or both a longer hospitalization and/or an early-aggressive nutritional support.
