Cricopharyngeal achalasia associated with congenital suprabulbar paresis.

A case of congenital suprabulbar paresis is reported. The associated severe dysphagia which presented soon after birth was shown by radiographic and cineradiographic studies to be due to cricopharyngeal achalasia. During four years of follow-up a clear tendency to spontaneous improvement was seen. It is therefore suggested that the condition may have a favorable outcome without resorting to surgical intervention.

Gerstmann tetrad in leopard syndrome.

We report a 12-year-old boy with multiple lentigines (Leopard) syndrome who was evaluated for learning difficulties and Gerstmann tetrad syndrome (i.e., dyscalculia, left-right disorientation, finger agnosia, and dysgraphia). Cranial computed tomography revealed left ventriculomegaly, more pronounced in the occipital horn suggesting mild atrophy of the left parietal lobe. This is the first report of an association between the Leopard and Gerstmann syndromes and one of the few to demonstrate a computed tomographic abnormality in the latter.

Thyroid function in attention deficit and hyperactivity disorder.

In view of the recent conflicting findings regarding the causative role of thyroid abnormalities in attention deficit hyperactivity disorder (ADHD), we performed a replication study to clarify the issue and establish clinical guidelines. Thyroid tests were performed in 43 ADHD children and 28 age- and gender-matched controls. Sixteen ADHD children showed total triiodothyronine (TT3) levels which were slightly above the upper limit of normal, but no significant difference in TT3 values was noted between the ADHD and the control groups. Moreover, none of the ADHD subjects had abnormal levels of total thyroxine, free thyroxine, thyroid stimulating hormone or total triiodothyronine reuptake. The present study supplies additional evidence for the lack of an association between thyroid function and ADHD, and counters the suggestion that thyroid function be routinely screened for in ADHD children.

The public, the primary physician, and genetic counselling.

This article reviews the literature regarding variables that affect that likelihood that genetic counselling will be either requested by clients or suggested by primary care practitioners. Results of current research indicate that use of genetic counselling may be hindered by a lack of knowledge on the part of both physicians and the public, by such psychological barriers as fear of genetic disease and its attendant stigma, by cultural values that stress reliance on fate or God's will, by medical values that deemphasize clients' emotional needs and disease prevention and that stress active intervention by the physician, and by financial consideration. The findings suggest the need for research on 1) knowledge of and attitudes toward genetic disease, genetic counselling, and genetic screening among the general public, 2) variables affecting the public's response to genetic counselling and genetic screening programs in different socio-demographic communities, and 3) physicians' value systems and their effects on physicians' use of genetic counselling.

Visual pathway tumor: a heterogeneous tumor with a variable clinical course.

The aim of the study was to delineate the clinical characteristics of visual pathway tumor in children without neurofibromatosis-I. The authors reviewed the charts of all patients meeting these criteria (n = 12) who were followed in their center over a 13-year period. In 8 patients the disease was relentlessly progressive, and imaging showed a chiasmatic/hypothalamic, exophytic globular lesion. The remainder had a benign course with long periods of tumor stability; one showed some spontaneous visual improvement. The lesions of the latter subgroup were multilobular, with elongated posterior extension into the optic tract. This differentiation, according to the imaging findings, may have significant therapeutic implications. In the first type, every effort should be made to arrest the disease and decrease the size of the lesion, whereas in the second, despite decreased visual ability, careful observation in the appropriate approach. There are as yet no known biological markers to better delineate these two types of tumor behavior.
