Hospital discharge medication: is seven days supply sufficient?
The impact of a change in a District Health Authority's hospital medication discharge policy, from 14 to 7 days supply, was evaluated. This coincided with a revised initial discharge letter (prescription and clinical details combined). There was no significant difference between a 14 and 7 day supply with regard to whether GP's received an initial discharge letter, the number of days the letter took to arrive at the GP's surgery, the necessity for further treatment, or problems encountered in the continuity of a patient's treatment. However there was a significant improvement (P less than 0.01) in the quality of information on the new discharge letter as perceived by GPs. Provided the initial discharge letter has prescription details and is given to the patient to deliver to their GP, seven days supply of medication is sufficient.

Yaws infection in Tanna, Vanuatu 1989.
Yaws has been resurgent in the island of Tanna in southern Vanatu in the 1980's. Screening, conducted in 1988 and in 1989 during a mass treatment program identified a total of 464 clinical cases from the population of 20,200, a rate of 23 per thousand. Most of these (82%) were under 15 years of age. Serology was performed on 286 of which 23% were VDRL positive. Primary care services had been hampered in controlling yaws by difficulties with transport, isolation, community resistance and the lack of skilled personel to diagnose yaws and arrange prophylactic treatment. A mass screening and treatment program was implemented in 1989 with 91.8% coverage. This program was designed to work in the context of primary health care and thus has enhanced the relationship between the health services and local villagers. The program was successfully integrated with other health activities including health education, treatment of other diseases and vector control.

An update on HIV-testing at a London sexually transmitted diseases clinic: long-term impact of the AIDS media campaigns.
Trends in the number of tests for HIV-1 antibody at a London sexually transmitted diseases clinic showed substantial changes between September 1985 and June 1988. From an average of 100 tests per month between September 1985 and August 1986, the average increased to 365 tests per month for September 1986 to August 1987. This levelled off at 243 tests per month between September 1987 and June 1988. The average number of positive tests per month between September 1985 and June 1988 remained constant, though the number of seropositive tests in females increased. Male and female populations displayed similar temporal patterns. The greatest increase was seen in the tests generated by heterosexual males and females with no other risk factors. This group generated 42% of the 8012 tests performed during the study period. The Clinic's catchment area predominantly included London and surrounding areas and temporal patterns were similar for residents from each of the Thames Regions. The temporal patterns observed coincided with periods of increased media attention on HIV infection/AIDS and involved campaigns by the popular press, television, Department of Health Education Authority. The increase in tests during the time of maximum media exposure, the subsequent plateau at a level substantially higher compared with the period preceding the media campaigns and the large increase in heterosexual males and females tested, all suggest that the campaigns have contributed to increasing awareness of HIV infection/AIDS as a major contemporary public health problem.

Topical alpha-interferon in recurrent genital herpes simplex infection. A double-blind, placebo-controlled clinical trial.
We conducted a double-blind placebo-controlled clinical trial on 98 subjects to assess the efficacy of two strengths of topical human leukocyte alpha-interferon, 10(4) and 10(6) IU/g in a 1% nonoxynol-9 base, in the treatment of recurrent genital herpes simplex virus (HSV). The study medication was applied during the prodromal phase or at the first sign of recurrence of the infection. The high-dose alpha-interferon was found to be significantly more effective than the low-dose interferon and placebo with respect to the duration of viral shedding as well as in reducing the time to the end of all subjective symptoms, including pain, burning and itching. No difference between the three groups was found in times to crusting or healing. Further studies of topical interferon in the treatment of HSV and other viral infections are merited.

Risk factors for HIV-1 infection in a British population: lessons from a London sexually transmitted diseases clinic.
Between September 1985 and June 1988, 6923 people (4550 men and 2373 women) were tested for HIV-1 antibodies at a sexually transmitted disease clinic, London, UK. Of the 6923 individuals tested, 558 (8%) were seropositive, of whom 523 (94%) were men and 35 (6%) women. Of the seropositives, 84% were homosexual or bisexual men, 5% were intravenous drug users, 4% were heterosexual contacts of HIV seropositives, 4% had multiple risk factors, 2% were heterosexual contacts of central African partners and 1% were heterosexuals with no other risk factors. This prevalence pattern conforms to that observed in other industrialized nations. For the women, heterosexual intercourse with an HIV-infected partner, intravenous drug use and heterosexual contact with a partner from central Africa were the main risk factors for infection. The important risk factors among the men were heterosexual contact with an HIV-seropositive partner, being homosexual or bisexual, intravenous drug use and heterosexual contact with a resident from central Africa. heterosexual and homosexual transmission were implicated as the main routes for viral spread in this British population.

Decline of anti-p24 antibody precedes antigenaemia as correlate of prognosis in HIV-1 infection.
A cohort of 84 homosexual men presenting with persistent generalized lymphadenopathy (PGL) was studied between March 1982 and March 1987. A progression rate to AIDS of 5% per year was seen in those who were infected with HIV. Certain clinical features and routine laboratory investigations were significantly associated with an increased risk of disease progression, but had only limited predictive value. Two hundred and fifty-two serial sera from 57 patients were analysed for the p24 antigen (Abbott), the principal core protein of HIV and antibody against p24 by direct enzyme-linked immunosorbent assay (ELISA). Patients who remained well retained a high titre of anti-p24 antibody compared with those who progressed to AIDS-related complex (ARC) or AIDS. HIV antigen was detectable in 40% of AIDS patients 2 years before diagnosis, but antigenaemia was preceded by loss of anti-p24 antibody by up to 18 months and preceded AIDS by up to 40 months. ARC patients tended to be negative when tested for both alpha-p24 antibody and antigen, suggesting a transitional state. Analysis of the humoral response against gag proteins appears to correlate closely with clinical status and may be an earlier and more consistent way of predicting disease progression than p24 antigenaemia, or clinical and routine laboratory investigations.

Relationship between circulating interferon and anti-interferon antibodies and impaired natural killer cell activity in systemic lupus erythematosus.
Interferon (IFN) production and response are impaired in a high percentage of systemic lupus erythematosus (SLE) patients. In addition, elevated serum levels of alpha-IFN or anti-alpha-IFN antibodies are present in some SLE patients. This study examined the relationship of circulating IFN and anti-IFN antibodies to the impairment of natural killer (NK) cell function in SLE. All 15 SLE patients studied had measurable circulating alpha-IFN, while the normal controls had minimal serum IFN. Neither patient nor control sera contained any detectable anti-alpha-IFN activity. However, most of the SLE patients demonstrated defects in NK cell function. Because these defects in NK cell function appeared to be associated with circulating IFN, but not anti-IFN, antibodies, the effect of prolonged in vitro IFN exposure on NK cell function of peripheral blood mononuclear cells was determined. It was found that prolonged exposure to IFN induced both an apparent defect in IFN response and a definite impairment of baseline NK cell function. These results suggest that prolonged elevation of circulating alpha-IFN levels could be responsible, in part, for the defects in natural cytotoxicity present in SLE.

Lymphokines in autoimmunity: relationship between interleukin-2 and interferon-gamma production in systemic lupus erythematosus.
Interleukin-2 (IL-2) and interferon (IFN) are potent immunoregulatory factors. Recently, it has been demonstrated that IL-2 production is necessary for IFN-gamma synthesis. Thus, defects in IL-2 production could lead to defects in IFN-gamma production. Indeed, in systemic lupus erythematosus, defects in IFN-gamma and IL-2 production have been noted. To test this hypothesis, IL-2 and IFN-gamma production rates by peripheral blood mononuclear cells PBMC were measured simultaneously after stimulation by concanavalin A (Con A) and phorbol myristic acetate (PMA). IL-2 activity was determined employing HT-2, a cell line with an absolute growth requirement for IL-2. IFN-gamma activity was assessed using a standard viral plaque inhibition assay. IL-2 production in normal controls (n = 6) was 14.7 +/- 9.4 units/ml and in SLE patients (n = 10), 18.0 +/- 10.5 units/ml (P greater than 0.05). IFN-gamma production in controls was 74.7 +/- 43.7 units/ml and in SLE patients, 68.8 +/- 35.4 units/ml (P greater than 0.05). Only one SLE patient, who had moderately active disease, demonstrated defects in IL-2 synthesis (less than 4 units/ml) and IFN-gamma production (16 units/ml). Thus, production of these lymphokines in SLE patients was largely normal in response to Con A-PMA. These results imply that the intrinsic pathways of IFN and IL-2 production are basically normal in most SLE patients although defects in production of these lymphokines can occur. The defects in IL-2 and IFN production in SLE previously reported may be secondary to an impaired cellular response to the selected inducing agent rather than a primary defect in the actual ability to produce these important lymphokines.

Comparative study of DNA methylation in three unicellular eucaryotes.
We have analyzed the nature/content of methylated bases in the nuclear DNA of three unicellular eucaryotes. The pattern of methylation was different for each of the three organisms studied: Saccharomyces cerevisiae contained only 5-methylcytosine; Tetrahymena pyriformis contained only N6-methyladenine; and Chlamydomonas reinhardi contained both modified bases.

The educationally handicapped child. The physician's place in a program to overcome learning disability.
Under California Assembly Bill 464, special classes may be provided by school districts for children designated as educationally handicapped. An educationally handicapped child is not mentally retarded or physically disabled. He may have neurological handicap or emotional disorder, but he must show impaired achievement in relation to his tested abilities.A physician may be asked to participate in the program, either as a specified member of the admissions committee of the school district or to provide a medical clearance for entrance of one of his own patients into the program.He does a thorough history and physical examination but adds special examination of attention, activity, coordination and attitudes.The educationally handicapped child is helped most by the physician who does not reject the idea of educational handicap even if the medical examination is negative; who treats his minor ills; who medicates, when it is indicated, for hyperactivity, distractibility or extreme anxiety; who cooperates with parents and school personnel.

Nursing intuition: can it be researched?
Drawing on the work of Gilligan (1982) and Heidegger (1962), this article explores the topic of intuition. It examines whether nursing intuition can be researched, if it is possible to develop a language of intuition, and if it is related to 'hands-on' experience.
