Dermatoglyphics in juvenile hypertension.

Dermatoglyphics of 172 children and young adults (116 males, 56 females) with hypertension, 13-27 years old, were compared with those of 130 healthy male and 110 female controls. Several differences were observed between the two groups. Hypertensive patients had a somewhat lower frequency of fingertip ulnar loops, higher frequency whorls and a higher total finger ridge count. They also had a somewhat higher mean atd angle, significantly more frequent distal position of the axial triradius (mostly in t' position) and more missing axial triradii compared to controls. The differences between a-b ridge counts, the interdigital, thenar and hypothenar patterns were generally small and sometimes limited to one sex or one hand only. The observed differences seem to indicate a genetic influence in the etiology of essential hypertension.

A family with amyotrophic lateral sclerosis and Parkinsonism.

Amyotrophic lateral sclerosis (ALS) and Parkinson disease (PD) are known to occur simultaneously among some Chamorro inhabitants of Guam and other Mariana Islands (Stanhope et al., 1972). Outside of the Western Pacific Islands, the concurrence of ALS and PD seems to be rare. However, it has been observed to occur with sufficient frequency to suggest some causal association. The following is a report of a patient suffering from ALS whose family history included PD in several of the immediate relatives.

Hereditary Amyotrophic Lateral Sclerosis. A report of two families.

An aggregation of 14 cases of amyotrophic lateral sclerosis (ALS) was encountered in two families in Minnesota. Although the classical clinical features of ALS predominated, some members of one family showed, in addition, extrapyramidal signs, peripheral sensory impairment in the upper and lower limbs and mild mental fallout. Autosomal dominant inheritance with incomplete penetrance was the most likely mode of transmission. Pathological changes were the same as those seen in sporadic ALS although one patient also showed degeneration of the substantia nigra. These two families were compared to others in the literature and an effort was made to refine the classification of familial ALS.

The Saethre-Chotzen syndrome.

The Saethre-Chotzen Syndrome (SCS) is characterized by craniosynostosis, low-set frontal hairline, parrot-beaked nose with deviated septum, ptosis of the eyelids, strabismus, refractive error, tear duct stenosis, dystopia canthorum, brachydactyly and abnormal dermatoglyphic patterns. The syndrome follows an autosomal dominant mode of transmission with complete penetrance and variable expressivity. Many cases of SCS have been previously reported but erroneously diagnosed as Crouzon syndrome, "pseudo-Crouzon" syndrome, simple craniosynostis, microcephaly or other inappropriate diagnostic category. Based on the findings in 6 kindreds with 31 affected individuals and an analysis of well-documented cases from the literature, the syndrome is delineated. Close attention to minor skeletal anomalies and "incidental" findings is emphasized.
