Air weapon fatalities

AIMS: To describe characteristics of a series of people accidentally and deliberately killed by air powered weapons. METHODS: Five cases of fatal airgun injury were identified by forensic pathologists and histopathologists. The circumstances surrounding the case, radiological examination, and pathological findings are described. The weapon characteristics are also reported. RESULTS: Three of the victims were adult men, one was a 16 year old boy, and one an eight year old child. Four of the airguns were .22 air rifles, the other a .177 air rifle. Two committed suicide, one person shooting himself in the head, the other in the chest. In both cases the guns were fired at contact range. Three of the cases were classified as accidents: in two the pellet penetrated into the head and in one the chest. CONCLUSIONS: One person each year dies from an air powered weapon injury in the United Kingdom. In addition there is considerable morbidity from airgun injuries. Fatalities and injuries are most commonly accidents, but deliberately inflicted injuries occur. Airguns are dangerous weapons when inappropriately handled and should not be considered as toys. Children should not play with airguns unsupervised.     

Teenage sex talk

Although an international study recently revealed that 87% of the UK's teenage mothers are unmarried, the highest figure in the world according to Alan Guttmacher Institute data of 1998, the teen conception rate in the country has declined considerably over the past 25 years and the number of teen mothers has been almost halved. Teens, as well as couples in other age groups, are increasingly cohabiting outside of marriage rather than getting married; more than two-thirds of babies born to teenagers are jointly registered by both parents. However, despite the decline in teenage conceptions since 1970, the UK still has one of the highest rates in Europe. The UK's real scandal is its failure to give young people the information they need to manage their sexual health. International research has proven that sexual health can be improved if societies are open about sex, accept teenage sexuality, and permit discussion about sex without embarrassment. Moreover, sex and relationships education should start at an early age, and young people should have easy access to free and confidential sex advice. Individuals under age 16 years have the right to the same degree of confidentiality as that afforded to adults. Vast potential exists for nurses to increase teenagers' use of services by removing the key obstacles which deter them from seeking advice: fears about confidentiality, lack of service publicity, and inappropriate opening times.     

Teenage primigravidae: a comparative study

A review of history sheets of obstetric cases recorded in a district hospital in 1992 was done to compare the obstetric outcome in 200 teenage first pregnancies (Study group) with that in Control group i.e. 20 years to 29 years. It revealed that incidence of complications of pregnancy like anaemia, pregnancy induced hypertension (PIH) and preterm labour were significantly higher among teenage mothers. The normal mode of delivery was commoner in teenagers (82.5%) in comparison to control group (76.5%), probably because of higher number of low birth weight babies. The fetal outcome was significantly worse in teenage mothers with high incidence of perinatal mortality (8%) and low birth weight babies (35%). There was not a single newborn with birthweight above 3500 gms, in teenage group, whereas, control group had 5 babies (2.5%) in the category.     

Motor vehicle fatalities in the United States construction industry

Photographs (study 1) or line-drawing representations (study 2) of posed facial expressions and a list of emotion words (happiness, surprise, fear, disgust, anger, sadness, neutral) were presented to two groups of observers who were asked to match the photographs or line drawings, respectively, with the emotion categories provided. A multidimensional-scaling procedure was applied to the judgment data. Two dimensions were revealed; pleasantness--unpleasantness and upper-face--lower-face dominance. Furthermore, the similarity shown by the two-dimensional structures derived first from the judgments of photographs and second from the line drawings suggests that line drawings are a viable alternative to photographs in facial-expression research.     

Work-related road fatalities in Australia, 1982-1984

A study of work-related fatalities, based on coroners' records, has provided national data on work-related road fatalities. A total of 1,544 work-related fatalities were identified over 1982-1984. Of these, 600 (39%) resulted from injuries sustained in road vehicle accidents on public roads; 366 (24%) in the course of work, and 234 (15%) while commuting between home and work. These figures are likely to underestimate work-related road fatalities because the coroners' records often did not contain the required information. The incidence of road fatalities declined slightly over the three years, although the proportion amongst all work-related fatalities remained constant. The at-work victims tended to be older than victims of road death generally. Fifty-six percent of the at-work cases were in the occupational group "drivers, road transport". Articulated trucks accounted for 41% of the at-work cases. Drivers made up 79% of the at-work group. In contrast, drivers accounted for only 38% of all road deaths. Two-thirds of the at-work road fatalities occurred outside capital city districts, the proportion of nonmetropolitan cases being highest for deaths involving articulated trucks. This is striking, in view of Australia's highly urbanised population. Blood alcohol data were available for 76% of the at-work cases and 79% of the commuting fatalities. Of these, 15% and 13%, respectively, had a blood alcohol of 0.05 g/100mL or more. In contrast, 6% of other workplace fatalities for which blood alcohol data were available had such levels. This difference may reflect more assiduous blood-alcohol testing of road-accident victims.(ABSTRACT TRUNCATED AT 250 WORDS)     

Teenage status of hyperactive and nonhyperactive learning disabled boys

Three groups of learning disabled boys--hyperactives, normoactives, and hypoactives--were studied in grade school, reevaluated at fourteen. At follow-up, all three groups remained at disadvantage to controls on academic and cognitive measures and on complex reaction time. Half the hyperactives had experienced major conflicts with authority, and over a third of hypoactives exhibited psychologically disturbing behaviors. Mental health of normoactives appeared comparable to controls.     

Commercial logging fatalities in Ontario, 1986-1991

Steady progress in the delineation of prognostic factors and the identification of genetic alterations and of potential mechanisms of oncogenesis mark the contributions to the literature on osteosarcoma for the past year. A new cytokine and chemotherapy combination has shown promise, and additional work on chemotherapy regimens containing ifosfamide will undoubtedly stimulate interest in a new generation of randomized clinical trials that will be essential for further refinement of therapy for osteosarcoma.     

Teenage smoking, attempts to quit, and school performance

OBJECTIVES: This study examined the relationship between school performance, smoking, and quitting attempts among teenagers. METHODS: A logistic regression model was used to predict the probability of being a current smoker or a former smoker. Data were derived from the 1990 California Youth Tobacco Survey. RESULTS: Students' school performance was a key factor in predicting smoking and quitting attempts when other sociodemographic and family income factors were controlled. CONCLUSIONS: Developing academic or remedial classes designed to improve students' school performance may lead to a reduction in smoking rates among teenagers while simultaneously providing a human capital investment in their futures.     

Telescopic lenses and driving

In some states, persons with significantly reduced visual acuity are being licensed to drive while wearing telescopic spectacle lenses (TSL). In order to evaluate possible visual field limitations present with these devices, the peripheral visual fields of a group of normally sighted subjects were measured while they wore TSL. Severely restricted central fields and sizeable ring scotomas were present with all units tested. These result indicate that driving with TSL should be discouraged.
