The association of acne vulgaris with diet.

Acne vulgaris is a common disorder of the pilosebaceous unit affecting adolescents and adults. The rise in incidence of acne in the United States may relate to the Western diet--which is rich in dairy and refined sugars, and high in glycemic load--and to the obesity epidemic. We reviewed the literature on diet and acne.

Medical phototherapy in childhood skin diseases.

Phototherapy is used for the medical care of cutaneous conditions that do not respond to topical or systemic medical agents, and for conditions that require broad exposure to UV as a stabilizing agent for disease. Numerous wavelengths and delivery devices of ultraviolet light are used in childhood. This article is a brief overview of the medical usage of phototherapy in childhood.

The effects of external mechanical stimulation on the healing of diaphyseal osteotomies fixed by flexible external fixation.

OBJECTIVE: The purpose of this study was to investigate the effect of an externally applied mechanical stimulus on fracture healing under flexible fixation. DESIGN: Stimulation of fracture healing under various conditions of interfragmentary movement in an in vivo fracture model on 41 sheep. BACKGROUND: It is generally accepted that small interfragmentary movements (IFMs) yield better bone healing results than larger IFMs (> 1 mm).

The impact of dietary protein intake on serum biochemical and haematological profiles in vervet monkeys.

This study evaluated the influence of Westernised and traditional African diets on biochemical and haematological profiles in vervet monkeys (Cercopithecus aethiops). Twelve adult male vervet monkeys bred at the Medical Research Council, all over 4 years of age and weighing more than 5 kg each, were divided into two groups of six individuals. These monkeys were raised on a standard in-house diet post-weaning, before they were fed for 8 weeks on diets containing milk solids (17.

Effect of dietary plant and animal protein intake on sperm quality in monkeys.

This study was conducted to evaluate the influence of animal and plant protein diets on sperm quality indices over 120 days, using the vervet monkey (Cercopithecus aethiops), as a model. These experiments were divided into a 60-day period of high-protein consumption (+/-17% crude protein), followed by a 60-day term of sustainable protein intake (+/-9% crude protein). All the diets were designed to be similar, except for the source of dietary protein that the animals consumed.
