Effect of low fat diet on lipid absorption and fatty-acid transport following bowel resection.

Low-fat diets (LFD) are used extensively in many different clinical conditions. However, the effect of this diet on lipid absorption and cellular long-chain fatty-acid (LCFA) transport is unknown. Fatty-acid translocase (FAT), the rat homologue of human CD36, is one of several LCFA plasma-membrane transport proteins that may play an important role in intestinal lipid uptake. The purpose of this study was to investigate the effects of a LFD on intestinal expression of FAT/CD36, enterocyte fatty-acid transport, and in-vivo lipid absorption in rats following bowel resection. Adult male Sprague-Dawley rats were divided into five experimental groups: normal rats fed normal chow(NR-NC) (10 kcal% fat), normal rats fed a LFD (NR-LFD) (3 kcal% fat), sham rats fed normal chow (Sham-NC), short-bowel syndrome rats fed normal chow (SBS-NC), and SBS rats fed a LFD (SBS-LFD). SBS rats underwent 75% small-bowel resection, while sham animals underwent bowel transection and reanastomosis. Food intake, fecal mass, and fecal fat were measured over the last 3 days before death on day 14. Final body weight, plasma lipids and protein, and tissue total lipids in liver, adipose tissue, and intestine were determined at death. Total RNA from the mucosa of the duodenum, jejunum, and ileum was extracted for Northern blot analysis to determine fatty-acid translocase (FAT)/CD36 mRNA levels. An established cellular LCFA transport assay was used to determine isolated enterocyte [3H]-oleate uptake. Students t-test was used to determine statistical significance (P < 0.05). NR-LFD rats demonstrated a small increase in overall food absorption and no change in fat absorption compared to NR-NC animals. A significant decrease in FAT/CD36 mRNA levels was seen in the duodenum and jejunum in NF-LFD rats (vs NR-NC) and was accompanied by reduced LCFA transport by isolated enterocytes from the jejunum and ileum. SBS-LFD rats demonstrated decreased FAT/CD36 mRNA levels in all three segments and a concomitant decrease in LCFA uptake enterocytes compared to the SBS-NC group. In addition, SBS-LFD rats showed significantly lower final body weight and plasma lipids compared to SBS-NC animals.

Use of N-butyl-2-cyanoacrylate in elective surgical incisions--longterm outcomes.

BACKGROUND: Histoacryl Blue (N-butyl-2-cyanoacrylate) is a tissue adhesive that has been used clinically for more than 20 years. In the last decade, N-butyl-2-cyanoacrylate has been used for cutaneous closure of low-tension lacerations in children and adults and has become a preferred method for closure of pediatric facial lacerations in many emergency rooms outside the United States. Many pediatric elective surgical procedures are performed in tension-free areas and may be suitable for closure with a tissue adhesive. In order to assess this approach, a retrospective study was conducted to evaluate the cosmetic outcomes and complications of the application of N-butyl-2-cyanoacrylate for the approximation of elective surgical incisions in a pediatric population. STUDY DESIGN: Records of 1,098 patients, ages 1 month to 16 years, who, between January 1995 and December 1996, underwent one of the following: orchidopexy, inguinal hernia, umbilical hernia, or hydrocele repair were analyzed. In all patients, N-butyl-2-cyanoacrylate was applied to close the surgical incision. A 12-item questionnaire was created to assess the presence of complications and to determine shortterm and longterm cosmetic outcomes of the incision. Data were collected by conducting telephone interviews of family members. RESULTS: Among the 1,033 children who were treated, 66% had inguinal hernias, 15% hydroceles, 15% undescended testis, and 4% umbilical hernias. Redness or tenderness at the incision site (5.5%), discharge from the surgical wound (1.9%), and wound dehiscence (1.1%) were the main immediate complications after surgery. Overall satisfaction with the cosmetic outcomes of the surgical scar was high, with an average score of 4.73 out of 5 (94.6%). CONCLUSIONS: Our results demonstrate that administration of N-butyl-2-cyanoacrylate for the closure of small low-tension surgical incisions in the pediatric population is safe, has a low complication rate, and produces excellent cosmetic outcomes.

Foreign-body appendicitis.

The authors report the case of a 9-year-old boy who had a needle in his appendix. The contrast between absence of clinical symptoms and clear inflammatory changes of the appendix is noted. The authors recommend appendectomy for patients with pointed foreign bodies in the appendix to avoid inflammation and perforation.

[Percutaneous drainage of pancreatic pseudocyst in children].

Pancreatic pseudocysts in children are usually the consequence of blunt abdominal trauma. Spontaneous resolution can be expected in up to 50%, while surgical drainage is required in the others. Percutaneous drainage of these pseudocysts has recently been reported to give good results. We present a 7-year-old boy treated successfully with percutaneous drainage of a traumatic pseudocyst of the pancreas.
