RESUMO
Inflammatory bowel disease consists of multifactorial diseases whose common manifestation is inflammation of the gastrointestinal tract and their pathogenesis remains unknown. This study aimed to analyse the gene polymorphisms in Brazilian patients with inflammatory bowel disease. A total of 101 patients diagnosed with inflammatory bowel disease were analysed for the tumour necrosis factor-alpha (-308 G/A; rs1800629) and interleukin-10 (-1082 G/A; rs1800896) gene polymorphisms. Genotyping was performed through polymerase chain reaction-sequence-specific primer, then fractionated on 2% agarose gel and visualized after staining by ethidium bromide. The anatomic-clinical form of Crohn's disease (CD) predominant was the inflammatory (32.75%), followed by fistulizing (29.31%) and 27.58% stricturing. As control group, a total of 136 healthy subjects, from the same geographical region, were enrolled. The statistical analyses were performed using R program. The frequency of the A allele at tumour necrosis factor-alpha was high in ulcerative colitis (UC) patients (51%) than in controls (22%; P > 0.01). No statistical difference was found with the genotypic and allelic frequencies of CD patients compared to controls (P = 0.54). The polymorphism -1082G/A of interleukin-10 was not statistical different between the diseases compared to controls. Tumour necrosis factor-alpha (TNF-α) (-308G/A) is associated with UC onset, suggesting that the presence of -308A allele could confer a relative risk of 3.62 more to develop UC in general population. Further studies, increasing the number of individuals, should be performed to ratify the role of TNF-α in the inflammatory bowel disease pathogenesis.

The spleen is an important component of the immunologic system, especially in children. Splenectomy may result in immunologic deficiency, and splenic salvage is recommended as management in splenic surgery. PURPOSE--Splenic injury management, considering splenic salvage as a safe therapeutic option in these children. METHODS--One hundred and thirty nine (139) children, aged 5 months to 12 years were at João XXIII Hospital, Belo Horizonte, Brazil, for the period of 1981 to 1990. The causes of the trauma, the extent and the management of splenic injuries were evaluated. Hemodynamic instability with shock occurred in 30% of the children. The contusions were responsible for injury in 135 patients (97.2%) with 58.7% caused by pedestrian/motor vehicle accidents 41.6% of splenic injury were grade I and II, 30.6% were grade III, and 26.5 grade IV e V (Injury Scalling Committee). RESULTS--Non operative management was done in 2 patients and 137 were operated on. Conservative surgery was performed in 98 patients (71.5%), which included: splenorraphy in 81 (82.6); partial splenectomy in 10 (10.2%), and laparotomy followed by observation in 7 (7.1%). Post-surgical hemorrhage occurred in one case after conservative surgery. Splenectomy was performed in 39 (28.5%) of the patients with 75-100% of the splenic injury classified in grades IV and V. Multiple associated lesions occurred in 87 children (62.5%). The mortality rate was 10.5%. Cranioencephalic trauma was the cause of death in 13 children. CONCLUSION--The splenic salvage is a possible option in the management of splenic injury in 70% of the cases. Nonoperative treatment of splenic injury depends on the physiologic status of the patient, CT scan demonstration of splenic injury and intensive care management. If there was an associated abdominal injury, there would be an indication for surgery.

Acceptability and tolerance of a mixture containing corn (60%), soybean (30%), and wheat (10%) were tested. The mixture was used in the recuperation of pre-school children suffering from 2nd. and 3rd. degree malnutrition. To enable a higher consumption the mixture was used in forty-four different forms. The mean daily intake of the mixture was 121.35g during the four months of the experiment corresponding to about two-thirds of the protein intake of every child. Tolerance was found to be high. Acceptance of the mixture was high (92.2%) indicating that the form in which a product to be tested is presented is a matter of great concern.
