Drunken driving and riding with a drunken driver: adolescent types at higher risk

Abstract

The leading cause of death of adolescents in developed countries is injury. Alcohol is a major contributor to adolescent injury. Most of the injury deaths in youth are caused by traffic crashes. Driving under the influence (DUI) and riding with a driver who is under the influence (RUI) of alcohol increase the risk of road crash. The focus of this study is how adolescents’ risk of DUI and RUI differ in relation to their experience of parental control and peer pressure to substance use, other risky behaviours and leisure time activities. The analyses are based on data from the European School Survey Project on Alcohol and Other Drugs collected from 15- to 16-year-old Finnish adolescents in 2015 (n?=?4049, response rate 88.7%). The study shows that problems tend to entangle in some adolescent groups in which DUI and RUI are also more common. Adolescents with higher probability of using various substances, of starting alcohol use at young age, of experiencing weak parental control, and high peer pressure are at higher risk of DUI and RUI. The results indicate that professionals and authorities handling underage DUI and RUI ought to consider adolescents’ situation as a whole.     

Formulation and in Vitro-in Vivo Evaluation of Sustained-Release Lithium Carbonate Tablets

The release of lithium carbonate incorporated into polymethylmethacrylate, poly vinyl chloride, hy-drogenated vegetable oil, and carbomer matrix tablets was studied in vitro. The formulation containing 10% carbomer showed a sustained-release profile comparable to that of a standard, commercially available, sustained-release preparation containing 400 mg lithium carbonate embedded in a composite material. In vivo the newly formulated and standard sustained-release lithium carbonate tablets were compared to an oral solution and conventional lithium carbonate tablets in 12 healthy subjects. These crossover studies showed that the sustained-release tablets produced a flatter serum concentration curve than the oral solution and conventional tablet, without loss of total bioavailability.     

Linksventrikuläre Unterstützungssysteme

Because of the lack of organs for heart transplantations, left ventricular assist devices (LVADs) have become more and more important during the last few years. They are used for both bridging the time until transplantation as well as destination therapy for patients who are not able or willing to undergo a heart transplantation. Forensic and clinical pathologists will increasingly be confronted with fatalities of patients with LVADs. Beside natural causes of death and typical unavoidable complications, technical problems and user errors must be resolved. Under certain circumstances a suicidal or homicidal manner of death by manipulation of the device also has to be considered.     

Pediatric ophthalmology: reasons for examination and disease pictures

A representative sample of 800 patients was taken from 15,000 children treated between 1972 and 1984 in the Department of Pediatric Ophthalmology of Frankfurt University Eye Hospital. Their charts were reviewed to answer two questions: what are the most frequent reasons for ophthalmological examination in children under 15 years old and what are the most frequent diagnoses? Ophthalmological examinations were most frequently scheduled because of strabismus, errors of refraction and trauma or inflammation of the anterior segment, though also in a large number of cases because of general diseases, most often neurologic diseases such as epilepsy or elevated intracerebral pressure. The diseases diagnosed ophthalmologically were classified as congenital or acquired eye diseases and congenital or acquired general diseases with ocular symptoms. The most frequent are indicated in the text. Acquired diseases were more frequent than congenital diseases, though this group proved to be much larger in pediatric patients than in adult patients.     

Effect of caffeic acid phenethyl ester on survival of axial pattern flaps in rats with ischaemia-reperfusion injuries.

Oxygen-derived free radicals have been implicated in the pathogenesis of tissue injury after ischaemia-reperfusion. Caffeic acid phenethyl ester (CAPE), an active ingredient of honeybee propolis, has been identified as having potent antioxidant and anti-inflammatory properties. We evaluated the ability of CAPE applied intraperitoneally in reducing tissue injury after ischaemia-reperfusion. To investigate whether treatment with CAPE modifies the concentrations of the endogenous indices of oxidant stress, we examined its effects on a model of flap ischaemia-reperfusion injury in rats. CAPE (10 micromol/kg) was given through the peritoneum before reperfusion. CAPE given intraperitoneally had an inhibitory effect on tissue injury after ischaemia-reperfusion comparable to that of a control group. The anti-inflammatory and antioxidant properties of CAPE may contribute to its suppression of tissue injury.     

Correction of webbed-neck deformity in Turner's syndrome

Summary A case of Turner's syndrome with the typical marked webbing of the neck is presented. A posterior approach is preferred for correction of this webbed neck deformity. A butterfly shaped portion of excess skin is excised and the margins of the defect mobilised as four flaps. The flaps are sutured with a very short midline vertical component, resulting in an almost X-shaped scar. The first procedure resulted in only a partial correction of the deformity and an excess of hypertrophic scar tissue. This was treated with a repeat of the procedure but the midline wounds was repaired with mulitple small Z-plasties. The final appearance of the neck was satisfactory in the lateral profile, but there was still some excess tissue posteriorly.
