Unexpected trends in the analysis of a questionnaire and interview procedure to detect transient cerebral ischemic attack in a female population.

By means of a case-control study, social and biomedical factors were considered in relation to transient cerebral ischemic attack occurrence as determined by questionnaire and interview among a population of females ( greater than 50 years of age) residing in the city of utrecht and surroundings. Contrary to earlier expectations, a greater TIA risk was found associated with: lower systolic and diastolic blood pressure, a low-salt diet for high blood pressure, lower body weight, smaller body surface, and use of medicines for cardiac insufficiency/arrhythmias and chronic anxiety. The importance of hemodynamic processes (i.e. hypotensive episodes of cerebral circulation) for TIA within the general population is emphasized.

Risk of infection in prolonged central venous catheterization.

Classically, duration of infusion was thought to increase the rate of contamination by catheters. The results of this study show that this is not true and that, to the contrary, there is a definite difference in contamination rates between the basilic and the jugular and subclavian veins. The advantage of the basilic way which exists whatever the pathologic condition must undoubtedly determine the choice of this way of catheterization rather than any other.

The biology of social attachments: opiates alleviate separation distress.

The possibility that brain opiate systems participate in the control of social affect was assessed by determining capacity of low doses of exogenous opiates (0.125-0.50 mg/kg oxymorphone, and 0.10-0.50 mg/kg morphine sulfate) to reduce distress vocalizations of socially isolated puppies. Low doses of opiates were capable of profoundly reducing crying as well as the motor agitation they exhibit during brief periods of social isolation. Since reductions in crying could be obtained with morphine in the absence of any gross behavioral disturbances, the possibility is entertained that brain opiates may function to control the intensity of emotions arising from social separation. Possible parallels between the biological nature of narcotic addiction and the formation of social bonds are discussed.
