Assessment of bullet injuries in the neck (a salutory lesson).

Bullet injuries in the neck are fortunately rare in England and Wales, although their incidence is increasing. Clinical assessment of the extent of the injury and the decision whether or not to explore the neck in the absence of obvious major visceral or vascular damage can be difficult. We report a case where a potentially fatal injury was not suggested by the patient's clinical condition and we recommend prompt exploration of bullet wounds in the neck whenever there is a possibility of vascular damage.

Post-operative haemorrhage in tonsillectomy and adenoidectomy in children.

A second anaesthetic for bleeding after adeno-tonsillectomy in children represents a significant hazard. The true incidence of this complication is assessed for over 20,000 operations. The incidence of bleeding after adeno-tonsillectomy was found to be the sum of bleeding post-adenoidectomy and post-tonsillectomy. Bleeding post-adenoidectomy is at least as common as post-tonsillectomy and both occur most frequently within 12 hours of operation. No reason for the bleeding occurring in these particular patients could be found.

Oncogenic transformation of non-permissive murine cells by viable equine herpesvirus type 1 (EHV-1) and EHV-1 DNA.

Primary cultures of BALB/c mouse embryo fibroblasts infected with as much as 100 PFU per cell of EHV-1 do not exhibit cytopathology or synthesize detectable amounts of EHV-1 specific RNA, DNA, or infectious virus. Addition of 1--2 microgram of non-fragmented EHV-1 DNA as a co-precipitate with calcium phosphate to monolayers of such non-permissive mouse cells resulted in the appearance, after 4--6 weeks, of foci of piled-up, morphologically altered cells. Cell lines established from such transformed foci exhibited a greatly increased growth rate, unlimited growth potential, aneuploid karyotype, and grew with colony formation in soft agar. Inoculation of 10(6) transformed cells into newborn syngeneic mice resulted in the formation of serially transplantable tumours (undifferentiated fibrosarcomas) with a 100% incidence within eight weeks. Infectious virus could not be rescued from the EHV-1 transformed or tumour-derived cell lines by growth in the presence of IUDR, by cocultivation with permissive horse cells, or by attempts to transfect permissive cells with transformed or tumour cell DNA. However, EHV-1 specific membrane antigens were detected in the transformed cells by immunofluorescence with hyperimmune anti-EHV-1 mouse serum, and the presence of a fragment of the EHV-1 genome was demonstrated in both the transformed and tumour cells. These results indicate that cells nonpermissive for replication of EHV-1 remain susceptible to neoplastic transformation by the EHV-1 genome.

Ecology of 350 isolates of group F Streptococcus.

The ecology of 350 strains of group F streptococci isolated from clinical material over a six-year period is described. The respiratory tract, particularly the throat, yielded the largest number of isolates. Wound swabs, mainly appendectomy, ranked second as a source of this organism, followed closely by the genitourinary tract. A significant proportion of strains was recovered from gastrointestinal sites. Dental abscess yielded several strains, often in pure culture, and the external auditory canal was identified as minor locale of the group F streptococcus. A few isolates were also obtained from blood, cerebrospinal fluid, and miscellaneous tissues.

Experience with Yersinia enterocolitica at The Hospital for Sick Children, 1972-74.

Thirty-six cases of Yersinia enterocolitica infection were detected in the years 1972-74. The form of the illness in young children was acute gastroenteritis and in older children "appendicular syndrome". Improved isolation and identification techniques have increased the laboratory recognition of this enteric pathogen.

Lesbian stereotypes.

The American Psychological Association's Committee on Gay and Lesbian Concerns (Herek, 1987) expressed a need for research that focuses specifically on the concerns of lesbians. To this end, we attempted to identify stereotypes about lesbians, as noted in 278 female nursing students' responses to open-ended questions. Content analysis of the responses revealed a number of consistent themes or stereotypes. The most prevalent stereotypes included lesbians' seduction of heterosexual women, lesbian "boasting," and the "masculine aura" of lesbians. None of the participant variables (age, educational level, social class, and type of nursing education) were significantly related to particular stereotypes. The impact of stereotypes on the acceptance of lesbians within society is discussed.

Lack of association between hypertension and hypothyroidism in postmenopausal women seen in a primary care setting.

BACKGROUND: Several studies undertaken in hospital-based specialty clinics have reported an association between hypertension and hypothyroidism. This work examines the association between these two common disorders in postmenopausal women seen within a primary care office setting. METHODS: Seven hundred seven postmenopausal women aged 50 years and older were studied using a cross-sectional design. Data on thyroid status, hypertension and risk factors, and patient demographics were collected from the office medical record. RESULTS: Overall, 45.4 percent of the population studied had hypertension and 10.9 percent had hypothyroidism. Compared with normotensive women, hypertensive women were significantly older (66.4 years versus 63.0 years, P < 0.0001) and had a higher body mass index (29.2 kg/m2 versus 26.2 kg/m2, P < 0.0001). Hypertension was significantly associated with diabetes mellitus and the use of NSAIDS (odds ratios [ORs] = 1.77 and 2.63, respectively). We did not find a significant association between hypertension and hypothyroidism (OR 1.04, 95 percent confidence interval 0.64 to 1.76 CONCLUSIONS: In this population of postmenopausal women we did not find hypertension to be associated with hypothyroidism.
