Structure and expression of the rat epididymal secretory protein I gene. An androgen-regulated member of the lipocalin superfamily with a rare splice donor site.

The complete rat epididymal secretory protein I (ESP I) gene was isolated from a genomic library constructed in bacteriophage lambda Charon 4A. The complete nucleotide sequence of the gene and its immediate 5' and 3' flanking sequences were determined. Interesting features include the presence of a rare, but functional, splice donor site (...GC) and the presence of a putative androgen-receptor-binding element. A detailed analysis of ESP I regulation was carried out after castration and subsequent testosterone treatment, demonstrating the requirement for androgens. Efferent-duct ligation and cryptorchism, on the other hand, had no effect on the steady-state concentrations of ESP I transcripts. Comparison of the exon/intron organization of the ESP I gene with those of members of the lipocalin superfamily provides strong support for a common ancestral origin.

Is a full team required for emergency management of pediatric trauma?

Pediatric trauma centers often do not meet the guidelines requiring a trauma team as recommended by the American Academy of Pediatrics (AAP). We reviewed our experience with a team consisting of a pediatric emergency physician, resident, nurse, and respiratory therapist. The surgical and pediatric critical care residents and staff were available within 5 minutes. We conducted a retrospective chart review of 146 patients (aged 8.1 +/- 4.8 years) between 1987 and 1989, with Injury Severity Scores (ISS) greater than or equal to 16 or admitted to the pediatric critical care unit. The time of presentation, surgical services consulted, and the nature of the injury were obtained from chart review. The Pediatric Trauma Score (PTS), the Revised Trauma Score (RTS), the Injury Severity Score (ISS), Glasgow Coma Scale (GCS) score, and Pediatric Risk of Mortality (PRISM) were used to determine the severity of insult and physiologic derangement on admission. The Modified Injury Severity Score (MISS) was determined and the Delta score for Disability Assessment was assigned at discharge. The Delta score was also determined at 3-month intervals up to one year. The probability of survival (Ps) was calculated, using the ISS and RTS. The Z statistic for this group of patients was then determined, using the Major Trauma Outcome Study (MTOS) methodology. The percentages of patients who were normal, disabled, and dead were 61%, 31.5%, and 7.5%, respectively, at 6 months follow-up. Eleven deaths were expected based on PRISM and TRISS analysis. Our mortality and morbidity figures were comparable with those of centers with teams based on AAP guidelines.(ABSTRACT TRUNCATED AT 250 WORDS)

Periampullary tumors: which ones should be resected?

Resection was carried out in 118 patients for periampullary lesions. Ninety-eight of these were adenocarcinomas and were treated by the Whipple operation, total pancreatectomy, or local resection (87 patients, 7 patients, and 4 patients, respectively). Diagnosis of pancreatic head carcinoma before resection was falsely positive in 27 percent of the patients. Mortality for radical resection was 4 percent. Five year survival for ampullary carcinoma was 32 percent, and for pancreatic head carcinoma it was 7 percent. Resection of all periampullary tumors is recommended, with the Whipple operation being the standard in most cases.

Single-layer large-bowel anastomosis: a report of 250 cases.

Single-layer mucosa-excluding intestinal anastomoses involving the large bowel were evaluated in 249 patients (250 procedures). All patients operated on electively had mechanical bowel preparation but not all received antibiotics. Forty-nine anastomoses were performed as part of emergency procedures in which antibiotics were given intravenously. Three leaks were noted in two patients, a rate of 1.2%. There were no deaths attributable to anastomotic dehiscence. These results compare favourably with both hand-sewn and stapled anastomoses described in the literature.
