Hormonal response during a fenfluramine-associated panic attack.

Secretion curves for prolactin, cortisol, TSH, and GH from a 37-year old woman with dysthymia and panic disorder with agoraphobia were determined one day prior to (day I), and during a panic attack (day II) associated with an oral dose of 60 mg dl-fenfluramine, a drug known to increase anticipatory anxiety. The increased cortisol secretion observed is discussed in relation to the hormonal correlates of anxiety and the possible role of depression, dl-fenfluramine, and serotonergic receptor sensitivity.

Seasonal affective disorder in a tropical country: a case report.

Seasonality and affective disorders in the Southern Hemisphere were investigated in populations living in latitudes (40 degrees S) equivalent to those of the studies conducted in the Northern Hemisphere. The authors describe a patient with bipolar II affective disorder who was living in a low-latitude area (São Paulo, latitude: 23 degrees 39' S). The patient experienced five episodes of affective disorder that began in the summer and were characterized by symptoms typical of an autumn-winter depression. During the last two depressive episodes, the symptoms remitted after a 4-week course of evening light therapy. The case calls attention to the possibility that seasonality may influence the natural history of affective disorders even in lower latitude regions.

Cosegregation of schizophrenia with Becker muscular dystrophy: susceptibility locus for schizophrenia at Xp21 or an effect of the dystrophin gene in the brain?

A family is reported in which four of five adult patients with Becker muscular dystrophy (BMD) also have schizophrenia or related spectrum disorders. Although the estimated lod scores are not sufficient to conclude the existence of linkage between BMD and schizophrenia, it is suggested that there may be an association between these two disorders. Two alternative hypotheses are proposed to explain such an association: (1) the existence of a susceptibility locus for schizophrenia and spectrum disorders on the short arm of the X chromosome at Xp21; (2) that these psychiatric disorders may result from an abnormality in the expression of the dystrophin gene in the brain.
