All-terrain vehicle injuries at Arrowhead Regional Medical Center (Level II): epidemiology, risks, and outcome.

The growing popularity of all-terrain vehicles (ATVs) has contributed to a rise in the number of injuries and fatalities nationwide. The Consumer Product Safety Commission reported 8,104 fatalities from 1982 to 2006 and over 146,600 emergency room-treated visits in 2006 with children 16 years of age and younger comprising roughly 29 per cent in both categories. To investigate the epidemiology and outcome of ATV-related injuries and to explore variables contributing to morbidity and mortality, we conducted a single-center, retrospective study of ATV-injured patients presenting to trauma emergency between 2003 and 2007 at a Level II trauma center.

Female gamete preservation.

The use of multiple agent chemotherapy and combined modality treatment of childhood and adolescent cancers has markedly increased survival rates. Thus, the majority of young cancer patients survive into adulthood and the potential long-term consequences of the therapies are of ongoing concern. Alkylating agents have proven to be the most toxic to the ovaries; however radiation is also extremely gonadotoxic.

Rare cause of vaginal bleeding in early puberty.

Study Objective: To document an unusual cause of vaginal bleeding in early puberty.

Design: Case Report.

Results: Clinical presentation with the aid of pelvic ultrasound pointed to the diagnosis of an endometrial polyp in this young adolescent prior to menarche.

A randomized, double-blind, multicenter study comparing a starting dose of 100 IU or 200 IU of recombinant follicle stimulating hormone (Puregon) in women undergoing controlled ovarian hyperstimulation for IVF treatment.

Purpose: To compare the efficiency and efficacy of two starting doses of recombinant FSH (follitropin-beta, Puregon) in women undergoing IVF treatment.

Methods: This prospective, randomized, double-blind, multicentric (N = 6) study included 192 women undergoing IVF using the long protocol of GnRH agonist who received either 100 IU or 200 IU of r-FSH per day. Gonadotropin dose adjustment was allowed after day 4 of stimulation.

What the paediatrician should know about paediatric and adolescent gynecology: The perspective of a gynecologist.

Gynecological problems are common in children but training in this subject is rare during paediatric postgraduate education. Knowledge in this area is important for providing comprehensive health care to children. The article explores the gynecological examination of the child and common gynecological disorders in the paediatric and adolescent age groups.

Obstetric outcome of adolescent pregnancies.

Background: To determine if adolescent pregnancies are at increased risk of poor obstetrical outcome compared with a general obstetrical population.Methods: A five-year retrospective review of the Toronto Hospital for Sick Children's Teenage Pregnancy Unit was carried out. Information was available on 209 patients < 19 years age between January 1994 and December 1998.

Ovarian cortex cryopreservation in pediatric and adolescent medicine.

Background: Increased pediatric/adolescent cancer survivor rates have enhanced awareness of long-term effects of therapy, specifically gonadal failure. Ovarian cortex cryopreservation may hold the promise of fertility for those at risk for ovarian failure due to medical therapy. The object of this study was to determine if an ovarian cryopreservation program is feasible and to define suitable candidates.

Effects of thioridazine and withdrawal dyskinesias on workshop performance of mentally retarded young adults.

The authors conducted a two-part study of the effects of thioridazine and withdrawal dyskinesias on the workshop performance of mentally retarded young adults. In part 1, 80 mentally retarded subjects were divided into five groups of 16 according to administration, discontinuation, or nonadministration of thioridazine. The major finding was that thioridazine can impair the workshop performance of mentally retarded individuals.

Effects of phenytoin withdrawal on matching to sample and workshop performance of mentally retarded persons.

The present study was designed to examine the effects of gradual phenytoin withdrawal on the matching to sample performance of three mentally retarded person. The percentage of correct responses per session served as the dependent variable, and the sample and comparison stimuli were red, green, and blue illuminations of translucent response windows. With two of the subjects, the sensitivity of a workshop assembly task to phenytoin effects was explored retrospectively.

Effects of thioridazine (Mellaril) on titrating delayed matching-to-sample performance of mentally retarded adults.

The effects of thioridazine on the performance of a titrating delayed matching-to-sample discrimination by four retarded adults was investigated. Trials began with the center of three response panels illuminated by one of three colors. The delay between depression of the center response panel and presentation of the two comparison stimuli on the side response panels varied according to the accuracy of the subjects' performance.
