Response of life threatening dimenhydrinate intoxication to sodium bicarbonate administration.

This is a report of an intentionally administered overdose of dimenhydrinate to a 4 month-old infant who subsequently presented with status epilepticus, coma, and life threatening ventricular dysrhythmias. Initial toxicologic analysis of the serum by fluorescence polarization immunoassay was positive for tricyclic antidepressants. Repeat analysis of the serum at 6 hours post ingestion by gas chromatography mass spectrometry analysis defined diphenhydramine 4.8 micrograms/mL. The infant was managed with IV sodium bicarbonate as utilized in tricyclic antidepressant intoxication. The dysrhythmias resolved and the infant recovered without sequelae.

The use of in situ hybridization to show human papillomavirus deoxyribonucleic acid in metastatic cancer cells within lymph nodes.

Southern blot hybridization has been used to identify human papillomavirus types in both primary tumors and lymph node metastases. However, this technique requires fresh-frozen tissue and is incapable of localizing deoxyribonucleic acid sequences to specific cell types in the tumor sample. In contrast, in situ hybridization precisely locates viral sequences within tumor cells while preserving cellular architecture. Further, in situ hybridization requires only small samples of formalin-fixed, paraffin-embedded tissues. Five lymph nodes (from four patients) containing metastatic cervical squamous tumor cells (identified with hematoxylin and eosinophil staining) were analyzed with in situ hybridization techniques with human papillomavirus type 16 deoxyribonucleic acid probes labeled with sulfur 35. The primary cervical cancer from all four patients had been shown to contain human papillomavirus type 16 sequences by Southern blot. Three specimens from two patients clearly showed the presence of human papillomavirus type 16 sequences within the nuclei of metastatic tumor cells, whereas two specimens were nondiagnostic most likely as a result of the small volume of cancer relative to the size of the lymph node. This information indicates that it is the tumor cells themselves that contain viral deoxyribonucleic acid and provides additional evidence linking human papillomavirus with cervical carcinogenesis.

Screening for hepatitis B and vaccination of injecting drug users in NHS drug treatment services.

Hepatitis B vaccines are now available for people at high risk of infection. Injecting drug users are at particular risk. A UK national survey of statutory drug treatment facilities was conducted to assess what screening and vaccination procedures were offered to drug takers. Of the respondents 64% did not screen for hepatitis B and 71% did not offer vaccination to hepatitis B negative individuals. However, 63% respondents said they would advise vaccination for injecting drug users who continued to share. Fifty-eight per cent thought that the partners of hepatitis B positive clients should be screened and 50% thought that vaccination of partners was advisable. A policy of screening and vaccination for hepatitis B is recommended.

Clinical features of patients attending a gender-identity clinic.

Of 106 patients attending a gender-identity clinic, 73% satisfied DSM-III criteria for transsexualism. These DSM-III positives had a significantly younger age of onset and were less likely to experience sexual arousal with cross-dressing than those who did not satisfy DSM-III criteria. They were also significantly more likely to fulfil a definition of 'core transsexualism'. 'Core transsexualism' may represent a subgroup within DSM-III criteria for transsexualism and its defining features in this study were an early age of onset, low sexual activity, lack of sexual arousal with cross-dressing and homosexual orientation. Of the whole sample, 23% were referred for gender reassignment surgery, of whom 100% were DSM-III positive and 60% were 'core transsexuals'.

Management of the pregnant opiate user.

Increasing numbers of women are seeking help for drug misuse. In addition to problems associated with drug dependence, there are also problems concerning child care, pregnancy and women's health. In this paper we discuss the management of the pregnant opiate user, effects of opiate use in utero and postpartum and ways in which non-drug services can assist in the early identification and treatment of these women.

Discrimination on the grounds of diagnosis.

The study used the methodology of randomly allocating case vignettes to a sample of British consultant psychiatrists to assess the influence of a past diagnosis of alcohol dependence on present treatment attitudes. The case vignettes either did or did not include the previous diagnosis of alcohol dependence and the sex of the 'case' was also randomized. Psychiatrists receiving the vignette with the diagnosis of alcohol dependence were more likely to rate the patient as difficult, annoying, less in need of admission, uncomplaint, having a poor prognosis and more likely to be discharged from follow-up. There was minimal sex difference. Psychiatrist with a special interest in addictions regarded people with a past diagnosis of alcohol dependence as less difficult to manage than their non-specialist colleagues. The implications for education and treatment are discussed.
