Deficiency of alpha-L-fucosidase.

A new form of alpha-L-fucosidase deficiency has been found in a 20-year-old severely retarded male. Additional signs include angiokeratoma corporis diffusum and anhydrosis. The skin lesion is due to an accumulation of residual bodies, presumably containing oligosaccharides and glycoproteins, in endothelial cells and fibrocytes. The enzyme activity in blood relatives indicates that the disease is inherited as a simple autosomal recessive trait that segregates according to Mendelian principles. Because the enzyme activity in the heterozygotes was consistently below that of normal controls, the carriers of the trait in this family could be ascertained.

Crying behavior and psychiatric disorder in adults: a review.

Crying is a common human behavior that is encountered in varied clinical settings. However, its relationship to mood and psychiatric disorders remains unclear. In this report, the relevant literature on the relationship of crying behavior and psychiatric disorders is reviewed. Two clinically distinct types of crying behavior are identified. The relationship of "functional" crying with mood is inconsistent, but some trends suggest an apparent reduction in the behavior with worsening depression. "Organic" crying has attracted relatively more attention recently and is associated with a wide variety of neurological lesions, but neither the cerebral localization of the behavior nor its relationship to coexisting mood is clear. The clinical typologies, possible functional roles, and etiology of the behavior are discussed, and suggestions are made for future research.

The nonfixated Austin bunionectomy: a retrospective study of one-hundred procedures.

A retrospective evaluation of 64 randomly selected patients with 100 nonfixated Austin bunionectomy procedures was performed. A radiographic and a clinical evaluation were performed, including an analysis of preoperative and postoperative angles as well as postoperative complications. This study demonstrates a similar complication rate for nonfixated Austin bunionectomies as compared with previous studies with internal fixation. Removal of the fibular sesamoid was performed in 90% of the cases and did not increase the incidence of hallux varus. The nonfixated Austin bunionectomy is an acceptable alternative to the correction of hallux valgus. If internal fixation is utilized, the most cost-effective device should be used.

Sex-determination and sex-preselection tests in India: modern techniques for femicide.

"In India during recent years techniques that were developed to detect genetic deformities in fetuses have been increasingly used mainly for determining the sex of fetuses so that female fetuses can be exterminated. This paper explores the factors underlying this practice and the related practice of preselecting the sex of offspring, examining both the widespread availability and use of sex-determination and sex-preselection techniques and the root causes of female devaluation in India. Also presented and analyzed are the responses of women's groups and the government to these uses of modern technology to carry out the ultimate abuse of women--not allowing them to be born."

The effect of acute ethanol consumption on the human retinal circulation: a study in diabetic and non-diabetic subjects.

The effects of acute ethanol consumption on retinal haemodynamics and retinal vascular autoregulation to oxygen in the human retinal circulation were studied in 10 diabetic (mean age +/- SD: 38.2 +/- 11.1) and 16 non-diabetic (mean age +/- SD: 32.4 +/- 8.8) subjects. Subjects drank 0.5 g of ethanol, as vodka, per kg of body weight, diluted in sugar-free orange juice. Retinal blood flow was determined using laser Doppler velocimetry and computerised image analysis. The effect of ethanol on oxygen reactivity, as a measure of autoregulation, was also determined after 60% oxygen inhalation. All subjects demonstrated a significant fall in mean arterial blood pressure (control group 3.3%, p = 0.04, diabetic subjects 5.7%, p = 0.05), after ethanol intake. Ethanol caused no significant change in retinal blood flow. Oxygen reactivity was found to be 38.3% (22.4-47.7, median and interquartile range) in the non-diabetic subjects at baseline, and 30.7% (10.8-42.1) after ethanol ingestion. In diabetic subjects, the oxygen reactivity was 33.2% (19.8-46.8) at baseline and 24.5% (21.1-32.1) after ethanol. In this study ethanol did not significantly affect retinal blood flow or impair autoregulation. These results suggest that the retinal circulation may be able to autoregulate despite the presence of ethanol, in contrast to other vascular beds where ethanol changes flow.
