Drinking and driving among rural youth

Data concerning rural youth drinking and driving practices werecollected from 622 junior and senior high school students innorthwest Ohio, utilizing an ex post facto cross-sectional survey-researchdesign. The results suggested that 69% of the sample had usedalcohol at least once. With regard to quantity of alcohol use,about 27% reported drinking four or more drinks at a sitting.Approximately 19% of the sample had driven under the influenceof alcohol and 35% had ridden in a car with an intoxicated school-agedriver; 35% had refused a ride from a friend who was intoxicated,while 43% had tried to stop a drunk friend from driving. Nosignificant differences were found between males and femalesregarding drinking and driving but grade level was a significantmoderating factor. As grade level increased, the frequency ofeach alcohol-related behavior increased substantially (P <0.01). This paper presents prevalence data concerning drinkingand driving among rural youth as well as recommendations forcommunity health education program development.     

Endothelial function and aqueous humor flow rate in patients with Fuchs' dystrophy

Using a two-dimensional scanning fluorophotometer, we studied 50 subjects with symmetric ocular involvement of Fuchs' dystrophy without epithelial edema. Twenty-six subjects with confluent or nearly confluent cornea gutata with increased corneal thickness and 24 subjects with mild to moderate cornea guttata with normal corneal thickness were compared to normal control subjects. There were no statistically significant differences in endothelial permeability between the three groups. Corneal thickness was significantly increased in the subjects with confluent to nearly confluent guttae, however. These results suggest that endothelial pump function may be affected in subjects with advanced cornea guttata with stromal edema.     

Body pain and treatment response in late-life depression.

OBJECTIVE: The authors investigated the influence of body pain on 1) time to treatment response and 2) suicidal ideation, in late-life depression. They hypothesized that higher levels of body pain would predict a longer time to and lower likelihood of response, and increased levels of suicidal ideation. METHODS: Subjects (N=187) were older adult outpatients (age > or =69 years), with current episodes of major depression, who were openly treated with paroxetine up to 40 mg daily and weekly interpersonal psychotherapy. Response was defined as 3 consecutive weeks of Hamilton Rating Scale for Depression at < or =10. Body pain was measured with the Bodily Pain Index of the SF-36 quality-of-life assessment. Authors used survival-analysis models on the responder sample to test the effect of body pain on response, after controlling for severity of depression. RESULTS: Overall response rate was 75.4%. Nonresponders reported more severe pain at baseline. After covarying for severity of baseline depression, no effect was found for physical pain on time-to-response or degree of suicidality. Bodily pain remained stable during acute treatment for responders, independent of depression response to combination psychotherapy and antidepressant treatment. CONCLUSIONS: Older adult patients with higher levels of physical pain can still respond to antidepressant treatment; however, reported bodily pain may be associated with a more difficult-to-treat depression.     

Sarcoglycanopathies: a multiplex molecular analysis for the most common mutations.

Sarcoglycanopathies (SGpathies) are highly frequent among severely affected limb-girdle muscular dystrophy patients. On the basis of the findings of 5 common mutations in the 4 sarcoglycan (SG) genes in the Brazilian population, we standardized a multiplex polymerase chain reaction-single-strand conformation polymorphism methodology for their concomitant analysis in DNA samples. The test was able to confirm the diagnosis in about 63% of new patients with a suspected SGpathy and was particularly important in patients in advanced stages of the disease, when obtaining a muscle biopsy for analysis may be very difficult. As common mutations have been described in several countries, this multiplex analysis could be useful for the diagnosis of SGpathies if established according to the most prevalent mutations in each population. Besides, even though the disorder studied is rare, the technique could be broadly applicable to other genes and disorders.     

Are Continuity Clinic Patients Less Satisfied When the Resident Is Postcall?

Due to recent public debate and newly imposed resident work hour restrictions, we decided to investigate the relationship of resident call status to their ambulatory patients' satisfaction. Resident continuity clinic patients were asked to rate their level of satisfaction on a 10-point Likert-type scale. Using multiple regression approaches, these data were then assessed as a function of resident call status. We found that in 646 patient encounters, patient satisfaction scores were significantly less when the resident was postcall, 8.99 ± 1.8, than when not postcall, 9.31 ± 1.3. We herein discuss etiologies and implications of these findings for both patient care and medical education.     

How we do it: Reinsertion of the stylet into the nucleus contour cochlear implant to facilitate second insertion. A helpful technique salvaging the cochlear implant device

• There are several causes for failure of appropriate position of the electrode array of the nucleus cochlear implant, e.g. incomplete insertion, extrusion, luxation, curling of the device, deviation, or false route. • If the position of the electrode array in relation to the modiolus is unsatisfactory, in order to salvage the cochlear implant one can reload the cochlear implant array with its stylet. • In order to reload the electrode array, primarily it needs to be removed from the cochlea and inserted into a small size suction tube (lubricated with just water). Then the stylet needs to be carefully straightened and inserted into the lumen of the array. • This technique is a relatively simple solution for unsatisfactory placement of the electrode array and can prevent discarding the precious cochlear implant.
