Platelet associated IgG, platelet survival, and platelet sequestration in thrombocytopenic states.

Platelet-associated IgG (PAIgG), platelet mean life span (MLS), and platelet sequestration sites were studied in 69 patients with immune (ITP) and presumed nonimmune thrombocytopenias (NTP). A shortened MLS was associated with elevated PAIgG (N = 46), and with normal PAIgG (N = 15). Four patients had a normal MLS, but elevated PAIgG, four patients were normal for both parameters.

[Hygienic relevance of devices for indoor air treatment].

Shortcomings regarding design, construction, operation (including emissions), maintenance/repair and control of buildings with rooms for the accommodation of persons may be the reason to install air conditioning devices. According to manufacturers' data, such devices may be applied for various purposes, e.g.

[The significance of air exchange for air quality in homes].

The air exchange is an important parameter for the quality of the air in living spaces. It should be guaranteed by appropriate construction measures, such as by the choice of air permeability of joints, that the air exchange rate in living spaces is high enough to reduce the concentration of pollutants emitted indoors. Based of the measurement of the air exchange rate in about 100 rooms, a minimum ventilation rate of 0.

Prevalence of abnormal involuntary movements ("spontaneous dyskinesias") in the normal elderly.

Advancing age has been associated with increased prevalence of abnormal involuntary movements in neuroleptic-treated patients. In order to investigate the possibility that the aging process itself might produce involuntary movements clinically indistinguishable from tardive dyskinesia, a group of healthy elderly volunteers were systematically examined. A 4% prevalence rate of mild involuntary movements was found, suggesting that the aging process itself is not likely to produce dyskinesias without other contributing factors coming into play.

Power Weight Training and the Female Athlete.

In brief: The development of optimal strength potential in American female athletes has been neglected. This study documents the response of 13 men and 13 women of college age to an intensive power lifting program designed to duplicate a program followed by competitive male lifters. The results identified two significant training concepts: (1) the full squat must be considered the cornerstone exercise, because it quickly stimulates overall strength increases in both men and women, and (2) the women had the same physiological ability as men to tolerate and adapt to the demanding physical stress of power lifting.

Familial occurrence of tardive dyskinesia.

Tardive dyskinesia remains a poorly understood consequence of neuroleptic treatment for psychiatric illness. To date, there have been no reports in the literature regarding the presence of dyskinetic symptomatology in first degree relatives or other family members. The following two cases reveal the development of abnormal involuntary movement in brothers with similar mental illness and treatment histories, and suggest the importance of examining neuroleptically treated relatives of an affected individual for dyskinesia and may suggest a genetic factor in vulnerability.

The prevalence of presumed tardive dyskinesia in psychiatric inpatients and outpatients.

Randomly selected psychiatric patients (271 total) were examined by raters blind to diagnosis and treatment history for the presence of abnormal movements. The prevalence of presumed tardive dyskinesia among neuroleptic-exposed patients was 4.6%.

Relationship between the B-mitten EEG pattern and tardive dyskinesia. A pilot control study.

The identification of patients at high risk for the development of tardive dyskinesia (TD) is a major problem in psychopharmacology. We found a possible relationship between the subcortical B-mitten EEG pattern and TD. Twenty-one TD pateints were matched on a number of relevant variables with 21 patients without TD.

Incidence of the 14 and 6 per second positive spike pattern in an adult clinical population: an empirical note.

Although 14 and 6 per second positive spiking in children and adolescents has received extensive investigative attention resulting in conflicting results and opinion, efforts to study this finding in adult populations have been almost totally neglected. The present study attempts to contrast the incidence of this EEG finding in an adult clinical psychiatric sample with similar incidence data derived froma historical normal adult control series. From 10 years of laboratory data, the presence or absence of positive spikes was noted in the waking and sleep EEGs of 2888 psychiatric patients aged 20 and above.
