Midproject findings from a study of the National Collegiate Athletic Association's policy on smokeless tobacco use.

In this paper we present midproject findings from a longitudinal survey of 5,000 male athletes at 56 randomly selected American colleges and universities. The study monitors athletes' compliance with and perceptions of the effects of an organizational policy that restricts smokeless tobacco (ST) use. In 1996 and 1997, 77% of users reported that they complied with the policy during competition. During the same period there was a significant increase in the number of users who complied with policy during practices and of those who credited the policy with contributing to a decline in their overall tobacco consumption (14% vs 68%, p < .001; 17% vs 23%, p < .01: respectively). The findings suggest that organizational policies that regulate ST use can have an impact on young adult ST use.

Cessation related perceptions and behavior of former and current smokeless tobacco users.

Four hundred fourteen former and 73 current users of smokeless tobacco were questioned about their experiences in giving up smokeless tobacco. Their responses were compared with those of 463 ex-smokers to determine whether former smokeless tobacco users differed from former smokers in using specific cessation techniques. Of the smokeless tobacco users, 77% were interested in quitting, but only 7% wanted to quit "now." Seven percent of the daily users reported that a college-based health or fitness professional had advised them to quit. Former smokeless tobacco users were significantly more likely than former smokers to report that smoking cigarettes was related to their efforts to give up smokeless tobacco than former smokers were to report using smokeless tobacco as a strategy to stop smoking, Former smokeless tobacco users were also significantly more likely than former smokers to report current tobacco use. Smokeless tobacco cessation programs based on the transtheoretical approach to behavior change are recommended.

Visual Evoked Potential (VEP)--dependable marker for CNS affection in thyroid diseases.

The mean latency and amplitude of P100 component of VEP were studied in forty three controls and eighty nine cases of thyroid dysfunction [Hypothyroid-28; Hyperthyroid-32 and probable Thyroiditis-29 (inclusive of 21 cytology proved)]. The mean latency in hypothyroid, hyperthyroid and probable thyroiditis subjects were 110.69, 111.41 and 109 m.sec in comparison to 101.91, 102.0 and 101.08 m. sec. respectively in controls (p < 0.005). The mean amplitude being 1.34, 6.34 and 2.41 microvolts in hypothyroid, hyperthyroid and probable thyroiditis subjects in comparison to 4.79, 4.16 and 4.59 microvolts respectively in controls (p < 0.005).

Chloramphenicol resistant enteric fever.

In recent times there have been several reports of chloramphenicol resistant enteric fever necessitating the use of other antimicrobial agents. Clinical profile of 15 chloramphenicol resistant patients of enteric fever was studied. Three such patients (20%) responded to chloramphenicol despite in vitro resistance to the drug. Hence chloramphenicol still remains the drug of first choice in enteric fever as a majority (68.4%--26 out of 38) of our bacteriologically proven enteric fever patients were cured by the drug. The remaining 12 cases responded satisfactorily to ciprofloxacin (46.7%), gentamicin (20%), and ofloxacin (13.3%). There was an increased incidence of complications among the 15 drug resistant cases as compared to 23 cases of chloramphenicol sensitive enteric fever observed during the same period.
