Lumbar hernias are rare lesions. They involve the extrusion of visceral contents through a defect in the posterolateral abdominal wall. Only 250 a 300 cases had been reported in the literature. They occur most often in the superior lumbar triangle (Grynfelt's hernia). All lumbar hernias must be treated with surgery and the preferable surgical approach is done retroperitoneally. Primary repair, autologous tissue or prosthetic material may be used to obliterate the defect. The authors report a case of Grynfelt's hernia in which polypropylene mesch was placed pre-peritonially.

[Opinion of the people in charge of the medical graduation disciplines at the São Paulo University Medical School on the 'curriculum evaluation program'].

Results of "Curricular Evaluation Program" (CEP) of Medical School of S. Paulo University (FMUSP) are presented. CEP numbers are obtained form students answers offered to a padronized questionnaire which included theoretical and practical aspects of curricular process. Authors asked for the opinion of curricular disciplines coordinators of FMUSP about CEP and concluded: 1. CEP has large or reasonable profitability for 95.3% of coordinators; 2. CEP questionnaire was considered adequate by 85.7% of respondents, but 42.8% mentioned deficiencies in questionnaire revitance to them; 3. CEP presents excellent performance at FMUSP departments level.

Scanning electron microscope study of the veins at the human esophago-gastric junction.

Cast of the mucosal and submucosal veins of the esophago-gastric junction were studied in five necropsy specimens by scanning electron microscopy to analyse some of the characteristics of their shape and surface. Two types of veins were described: 1) veins with circumscript, fusiform and/or ampullar bulges and relatively smooth surfaces; 2) veins with numerous, small bulges and blister-shaped micro-dilatations. The role of these features is considered in the formation of esophageal varices.

[Curriculum evaluation program of the University of São Paulo Medical School--results for 1993 and a 5-year analysis].

The following report contains the results of the "Curricular Evaluation Program" of University of São Paulo Medical School pertaining to the year of 1993 and to the five-year period between 1989 and 1993. This evaluation of all undergraduate courses was made by students, responding to questionnaires supplied at the end of each program. In 1993, 60.6% of programs were considered as very good programs. In relation to 1989-1993 period, are presented the results of a disciplines group of the 4th year and a internship stages of the 5th year.

Grynfelt hernia.

Lumbar hernias are very uncommon conditions. Less than 300 cases have been reported in the literature. They result from defects in the posterolateral abdominal wall. The authors report their experience with four lumbar hernias managed at the "Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo" from 1973 to 1993. Age ranged from 54 to 63 years. Three were female, two had right hernias and two had left ones. All patients were treated surgically. Three were repaired by simple suture. The main complications were early recurrence (one case) and infections (one case). In one, a prosthetic mesh (polypropylene) was used to repair the defect, and the recovery was uneventful. Surgical treatment is always indicated in Grynfelt hernia. Approximation of the muscles by primary nonabsorbable suture, grafts or prosthesis are very adequate therapeutic options for lumbar hernias.

[Program evaluation Curriculum of the University of São Paulo Medical School. For the year 1994 and the period 1989-1994].

The authors present the results of the Program of Curriculum Evaluation of the University of São Paulo Medical School for the year of 1994, as well as the 1989-1994 period. The academic year of 1994 wasn't a good year to the medical graduation regarding disciplines from the first to the fourth year; only 14.3% of the disciplines achieved 90% or more of "excellent" + "good". The disciplines held at internship continued, on the most, doing well. The analysis of the 1989-1994 period outstands different sequential evaluation.

[Teacher's opinions regarding graduation programs at the University of São Paulo Medical School--PAC-II].

The authors show the results of the "Curricular Evaluation Program" of University of São Paulo Medical School pertaining to the year of 1996. This program (PAC-II) is based on teachers' opinions regarding the subjects taught (1st to 4th grades) and hospital intern courses. The opinions collected concerning such programs were definitely favorable. Most of the teachers considered the programs to be either good or very good. It was also identified that the hospital intern courses were a little more valued than the other courses taught in the first four grades.

[Comparative analysis of PAC-I and PAC-II].

Comparison between the results of students' evaluation of the University of São Paulo Medical School with the results of the coordinators' evaluation of their own program is presented; 32 programs during 1996 were studied. In 50% of the cases, the students and professors evaluation were identical. In 28.1% of the cases, the evaluations made by students were higher than the professors' evaluation, mainly in clerkship. In 21.8% of the cases, the contrary took place mainly in the first to fourth year programs.

A morpho-quantitative study of the myenteric ganglia throughout the human digestive tract.

We have examined the sizes of nerve cells present in the myenteric plexus in the human esophagus, stomach, duodenum and sigmoid colon using a nonhistochemical method (Giemsa) in laminar preparations of the muscularis externa. The collagen and elastic system related fibers in the myenteric ganglia were also qualitatively evaluated. The major mean of perikaryal area was observed in the esophagus (489.97 micron 2 +/- 212.35 micron 2) and the minor in the sigmoid colon (241.64 micron 2 +/- 122.62 micron 2). There were no significant differences between the mean areas of the myenteric neurons in the stomach (284.77 micron 2 +/- 134.70 micron 2) and in the duodenum (291.39 micron 2 +/- 157.86 micron 2). In all regions a ganglionic capsule of collagen fibers with thin septa surrounding isolated or grouped neurons was observed. The elastic and elastic-related fibers (elaunin and oxytalan fibers) were also present in both the ganglionic capsule and inside the ganglia. There were no differences among the regions. These data suggest that factors such as size of nerve cells and structural aspects of the ganglionic capsule are not related with the incidence of megaesophagus and megacolon.
