Feasibility of School-Based Smoking Cessation Programs

ABSTRACT: This study obtained input from Australian student smokers approximately 15 years old, which may be useful in designing school-based smoking cessation programs. The sample was analyzed by previous quitting experience and intentions to quit. The order of preference for assistance options and incentives for quitting was similar across all groups: however, those who previously attempted to quit (previous quitters) and those who intended to quit (intenders) in the future were significantly more likely than non-quitters and non-intenders to find assistance options for quitting acceptable. The potential for saving money emerged as an important variable in convincing all groups of smokers not to smoke, and using personal willpower and cutting down slowly were identified as important in actual attempts to quit. The need for programs to be free and for friends to be supportive also was evident across all groups.     

Analysis of trauma intubations

The timing of trauma patient intubation is dependent on clinical presentation and clinician judgment. We sought to correlate the timing of intubation with the presenting of physiologic parameters and clinical outcome to identify potential quality assurance audit filters. Patients (n = 82) were grouped by timing of intubation: PREHOSPITAL, paramedic intubation; IMMEDIATE, within 10 minutes of arrival; DELAYED, beyond 10 minutes but within 2 hours of arrival; and NONURGENT, beyond 2 hours or at the time of surgery. While mean revised trauma scores and Glasgow Coma Scale (GCS) scores differed for the groups, the mean length of hospital stay and the incidence of aspiration pneumonia were not significantly different. In the DELAYED group, 80% of those who developed aspiration pneumonia had a GCS < or = 13. Patients in the NONURGENT group were older and commonly presented with tachypnea. The survival rate for the NONURGENT group was lower than predicted by the TRISS method (P = .004). A GCS < or = 13 and age greater than 50 years with presenting respiratory rates of more than 25 breaths/min represent potential trauma intubation audit filters.     

Squamous-cell carcinoma of the scrotum.

Squamous-cell carcinoma of the scrotum has a poor prognosis unless locally confined. Patients with stage A1 disease have approximately a 75% or better chance for long-term survival. Occupation-related and -induced scrotal carcinomas are less frequent now because of better hygiene, protective clothing, and awareness of the carcinogenicity of industrial oils. A rise in the incidence of the disease might result from the HPV epidemic. The basic treatment of squamous-cell carcinomas of the scrotum still depends on wide local excision of the primary lesion. Patients should be treated with a broad-spectrum antibiotic for 4 to 6 weeks prior to sentinel node biopsy or ilioinguinal lymphadenectomy. Sentinel node biopsy should be performed to rule out micrometastasis and to establish the need for a formal ilioinguinal lymphadenectomy. Radiation therapy has little therapeutic benefit in the management of squamous-cell carcinoma of the scrotum. Bleomycin might be useful as adjuvant therapy for widespread ilioinguinal disease before attempted resection, although this has yet to be proved.     

Ultra-fast velocity imaging in stenotically produced turbulent jets using RUFIS

A method for rapidly producing velocity images is presented. This sequence combines a modified bipolar gradient pulse to magnitude encode the velocity with the rotating ultra-fast imaging sequence (RUFIS) to image the encoded spins. Velocity encoding is done in 3 msec, and RUFIS acquires 32 projections in 8 msec. The method is applied to turbulent jets associated with a 75% stenosis in a 15-mm inner diameter glass pipe. Data is acquired upstream and downstream from the stenosis for Reynolds numbers from 560 to 3750. In addition, a robust method of reconstructing the unobserved short time region of a free induction decay is presented and incorporated into the image processing.     

Can we understand partnerships in general practice? A pilot study

BACKGROUND: Partnerships have been investigated in different professions,but other than identifying problems, little work has been carriedout on general practice. OBJECTIVE: The aim of this present study was to develop methods for studyingpartnerships in general practice. METHOD: A tripartite methodological approach was used, with questionnairesadapted from other instruments in use in other professions,followed by an individual interview with each partner, and non-participantobservation at a partnership meeting. Results for one case-studypartnership are given. RESULTS: There were no major differences between the partners on alldimensions measured; the minor differences indicated by theresults of the questionnaires were corroborated by the partnerinterviews and observations. CONCLUSIONS: We conclude that the use of such techniques could provide supportto partnerships going through significant periods of change. Keywords. General practice, interview, observation, partnerships, questionnaire.     

Fatal sepsis following intravesical bacillus Calmette-Guerin administration for bladder cancer

Intravesical administration of bacillus Calmette-Guerin has been shown to be highly effective treatment of superficial bladder cancer. Complications from bacillus Calmette-Guerin therapy are usually minor but serious and even fatal reactions can occur. Five recent cases illustrate the gravity of bacillus Calmette-Guerin sepsis. One man with severe debility and the organic brain syndrome died acutely with a fever of 40 C. Two men had frank sepsis that progressed to multiorgan failure and death. Sepsis progressed despite the use of isoniazid, rifampin and streptomycin. Two men who had equally progressive sepsis with intravesical bacillus Calmette-Guerin survived with the use of cycloserine for the first 72 hours of treatment. Triple antituberculous antibiotics, including cycloserine, may be lifesaving. Sepsis resulted from intravenous absorption through inflamed or disrupted urothelium. Bacillus Calmette-Guerin treatment should not be administered in the presence of severe cystitis or after grossly traumatic catheterization.     

Loss of carbamazepine suspension through nasogastric feeding tubes

The apparent loss of carbamazepine suspension during administration through polyvinyl chloride nasogastric feeding tubes in vitro was studied. Twelve methods of administering carbamazepine suspension (100 mg/5 mL) were tested; the methods differed with respect to nasogastric tube size, presence and type of diluent, and type of flush solution. Undiluted or 50% diluted carbamazepine suspension 200 mg was drawn up in a syringe and forced through adult or pediatric nasogastric feeding tubes. The tubes were immediately flushed twice with 50 mL of sterile water, 0.9% sodium chloride solution, or 5% dextrose solution, by using the same syringe used to administer the suspension. Samples were collected and analyzed for carbamazepine concentration by high-performance liquid chromatography. Each administration method was tested six times, and the results were subjected to analysis of variance. Significant loss of carbamazepine was noted for four of the six methods in which undiluted suspension was administered. In these methods, adult and pediatric tubes were flushed with sterile water or 0.9% sodium chloride. No significant loss of drug occurred for any of the methods involving the use of diluent. Significant losses were associated with diluent and flush solution but not nasogastric tube size. Carbamazepine suspension should be mixed with an equal volume of diluent before being administered through nasogastric feeding tubes.
