How normalised is HIV care in the UK? A survey of current practice and opinion.

OBJECTIVES: The prognosis for individuals infected with HIV has changed dramatically over the past 10 years, with patients living longer and requiring other specialist services. It is apparent that access of other healthcare professionals to clinical information about a patient's HIV care differs between centres in the UK. Lack of awareness of an individual's HIV status may compromise their clinical care. AIM: To establish current practice and identify the views of clinicians caring for patients infected with HIV. METHODS: Lead consultants in all genitourinary medicine departments in the UK were invited to complete a questionnaire regarding use of combined HIV and hospital notes and ability of general practitioners and other hospital specialists to access information about individual patient's HIV care. Clinician's opinions on the "normalisation" of HIV management were also sought. RESULTS: Combined notes (outpatient and inpatient) were used by 12% (16/130) of respondents. The patient's identifying number was used to request blood tests in 86%. Of the respondents, 42% had encountered difficulties in communication that affected delivery of care for an HIV-positive patient. CONCLUSIONS: Centres using combined notes identified a higher frequency of communication with other doctors and specialties, suggesting a higher standard of care. Physicians involved in HIV care should consider combining patients' HIV and hospital notes for improved clinical care.

Successful liver transplantation following medical management of portopulmonary hypertension: a single-center series.

Severe portopulmonary hypertension (POPH) is an absolute contraindication to orthotopic liver transplantation (OLT). Vasodilators have been used, but the safety of subsequent transplantation and the reversibility of pulmonary hypertension after transplantation are uncertain. This study examined the feasibility and post-transplant effects of liver transplantation following medical control of POPH. Eight consecutive patients (three females and five males, ages 39-51) with POPH as their only contraindication to transplantation were treated with continuous intravenous epoprostenol. Liver transplantation was considered if the mean pulmonary artery pressure (PAM) was lowered to <35 mmHg. Epoprostenol 2-8 ng/kg/min successfully improved hemodynamics in seven of eight patients, usually within 6.5 months of initiating therapy. PAM declined from an average of 43-33 mmHg (p=0.03); mean pulmonary vascular resistance declined from 410 to 192 dyn s cm-5 (p=0.01) and cardiac output increased from 6.6 to 10 L/min (p=0.02). Six of the seven responders were actively listed for liver transplantation. Two died on the waiting list; the remaining four were transplanted and remain alive and well 9-18 months post-OLT-two without vasodilators, and two on oral medication. We conclude that pulmonary vasodilators permit safe liver transplantation in some cases, and that POPH may be reversible after transplantation.

Adenoviral non-gonococcal urethritis.

Adenoviruses infect mucous membranes, including - on rare occasions - the urethra. Adenoviruses should therefore be considered as yet another cause of chlamydia-negative non-gonococcal urethritis. The following case illustrates the dilemma posed in a patient with conjunctivitis and urethritis.

Lichen sclerosus.

Lichen sclerosus (LS) is a chronic inflammatory disorder of the skin and mucosa, presenting to genitourinary physicians and dermatologists. It affects both sexes and all age groups. Although the exact aetiology is uncertain, genetic predisposition, infections and autoimmune factors have been implicated in its pathogenesis. Symptoms include pruritus and soreness, but asymptomatic presentations are not uncommon. The classical clinical picture is of atrophic white plaques in the anogenital region. Histopathology is specific with basal cell degeneration, upper dermal oedema, homogenization of collagen and a chronic inflammatory infiltrate. Short courses of potent topical corticosteroids form the mainstay of treatment. The condition tends to be remitting and relapsing, with spontaneous regressions reported in a few. In men, the term balanitis xerotica obliterans is sometimes used to describe late and severe LS of the penis. Scarring and progression to squamous cell carcinomas can occur in chronic LS, resulting in significant morbidity. A multidisciplinary approach to care and the need for long-term monitoring cannot be overemphasized.

Difficult wart cases -- use of imiquimod cream 5%.

Treatment of genital warts is a significant part of genitourinary medicine work load. Home therapies are the sensible way forward. Even problem cases can be managed successfully. Four difficult cases with successful outcomes are discussed.

New patient-applied therapy for anogenital warts is rated favourably by patients.

Our objective was to determine patient attitudes to having genital warts, and their perceptions of their treatment with imiquimod and other therapies. As an adjunct to a clinical trial in which patients with external genital warts were treated with imiquimod 5% cream until their warts cleared or for up to 16 weeks, quantitative questionnaires consisting of multiple choice questions and 5-point rating scales were completed prior to, and at the end, of the study period. Pre-study and post-study questionnaires were completed by 902 and 629 patients, respectively. Patients expressed a definite concern about genital warts. The majority of patients (70%) had been previously treated for genital warts, and expressed dissatisfaction with their previous therapies. Of patients treated with imiquimod in this study, 82% reported that their warts decreased in size; this occurred within the first 4 weeks for 78% of patients. Sixty-one per cent of patients perceived that their warts completely cleared within the 16-week treatment period. Patients rated imiquimod 5% cream as better than other genital wart therapies in terms of overall satisfaction, time to clearance, convenience and lack of associated pain. In conclusion, patients rated imiquimod 5% cream as an effective treatment which clears warts in an acceptable length of time causing minimal pain and is convenient to use.
