Oral beta2-agonist use by preschool children with asthma in East and Central Harlem, New York.

Although studies have documented underuse of controller medications and overuse of short-acting inhaled ss(2)-agonist among children with persistent asthma in disadvantaged communities, the persistence of oral ss(2)-agonist use in pediatric practice has not been studied since inhaled short-acting ss(2)-agonists became widespread. We describe medications used to treat asthma among children 3 to 5 years of age at 10 Head Start and other subsidized preschool centers in East and Central Harlem, New York City. We interviewed 149 parents/guardians of children who were identified as having probable asthma based on physician's diagnosis, persistent symptoms, hospitalization, and medication use. We classified 86 of the 149 children (58%) as having current persistent asthma. Only 15 of them (17%) were reported to have used controller medications at least 5 days/week in the last 4 weeks-only 2 of whom used inhaled corticosteroids. By contrast, 53 children (62%) used oral ss(2)-agonist in the last 4 weeks, often (72%) in conjunction with nebulized or inhaled short-acting ss(2)-agonist. Use of oral ss(2)-agonist was associated with more severe symptoms. This study documents the continued widespread use of oral ss(2)-agonist for treatment of children in a low-income community with high prevalence of asthma.     

Alcoholism in patients with sexual disorders

The authors screened for alcoholism 145 consecutive patients who presented with sexual dysfunction or disorders. Using the Michigan Alcoholic Screening Test (MAST), 29% of the patients scored in the probable alcoholic range. Probable alcoholics were more likely to present without a partner and claimed higher sex drive than nonalcoholic patients. Probable alcoholic males reported less joy and vigor than probable alcoholic females, while the reverse held for the nonalcoholic groups. Blind to the MAST results, the staff made six alcohol-related diagnoses and referred one patient for alcohol treatment. The authors discussed the importance of training faculty and resident staff in the relationship of alcohol abuse associated with psychosexual dysfunctions.     

Changing patterns of hip fracture care before and after implementation of the prospective payment system

We tested the hypothesis that since the implementation of the prospective payment system (PPS), elderly patients hospitalized for hip fractures receive shorter, less care-intensive hospitalizations and are more frequently institutionalized. In blinded fashion, we reviewed the charts of elderly patients with hip fractures admitted to a municipal hospital from 1981 through 1985. Demographic and clinical characteristics of patients treated before implementation of the PPS were similar to patients treated thereafter. After implementation of the PPS, the mean length of hospitalization fell from 16.6 to 10.3 days, and the mean number of physical therapy sessions received decreased from 9.7 to 4.9. Concomitantly, the proportion of patients discharged to a nursing home increased (21% to 48%), as did the proportion receiving nursing home care at six months after discharge (13% to 39%). This increase in long-term nursing home placement suggests that the quality of care for elderly patients with hip fractures may have deteriorated.     

Hepatitis A to G and beyond.

Recent advances in viral hepatitis reflect the progress of molecular biology. Their clinical applications may provide clues for future prevention.     

Transcranial Doppler to evaluate the effects of antihypertensive medication on cerebral blood flow velocity.

The effect of oral nifedipine on cerebral blood flow velocity was studied in six elderly hypertensive patients using transcranial Doppler. Serial measurements of blood pressure (BP), middle cerebral artery (MCA) flow velocity and nifedipine serum concentrations were obtained over an 8-hour period. The authors found a significant inverse relationship between MCA velocities and nifedipine concentrations, independent of BP changes. These results are consistent with a direct vasodilatory effect of nifedipine on cerebral vessels and support the use of TCD in pharmacodynamic investigations of the cerebral vasculature.
