SCREENING FOR ALCOHOLISM IN GENERAL MEDICAL PATIENTS

Medical patients (N = 108) were administered a brief screeninginstrument (LAMSI) and a structured diagnostic interview (SUDDS).Twenty-five patients met DSM-III criteria for an alcohol usedisorder, 20 current, five in remission. The four-item scaleembedded in the screen identified the alcoholics with 88% sensitivityand 96% specificity.     

SPECTRUM OF THYROID FUNCTION ABNORMALITIES IN GESTATIONAL TROPHOBLASTIC NEOPLASIA

The relative influences of the putative thyroid stimulator, pregnancy state and non-thyroidal illnesses, were assessed in 52 patients with gestational trophoblastic neoplasia (GTN). In this study biochemical thyroid status was assessed with the aid of thyrotrophin (TSH) measurements by a sensitive immunoradiometric assay and measurement of total and free thyroid hormone concentrations. The reference group consisted of 63 patients with normal pregnancy. Thyroid function in the GTN patients was also compared with that in 36 female patients with Graves' disease and 34 female patients with non-thyroidal illnesses. We found the major influence on thyroid functions in Group I ('Hyperthyroid') patients with GTN to be the presence of the thyroid stimulator, while non-thyroidal illnesses played an important role in Group II ('High T4 syndrome') and III ('euthyroid') patients with GTN. Thyroid function was also stimulated in Group II patients. The influence of pregnancy was seen in all three groups of patients with GTN, who had higher TBG concentrations than non-pregnant patients. We conclude that there is a spectrum of thyroid function abnormalities in GTN, and that thyroid function in an individual patient is determined by the relative influence of the thyroid stimulator, non-thyroidal illnesses and the pregnancy.     

An open-label efficacy pilot study with pimecrolimus cream 1% in adults with facial seborrhoeic dermatitis infected with HIV

BACKGROUND: Seborrhoeic dermatitis (SD) is a common dermatosis in human immunodeficiency virus (HIV)-positive patients, many of whom do not respond satisfactorily to conventional topical treatments such as corticosteroids and antifungals. OBJECTIVE: A pilot study to investigate the efficacy and tolerability of pimecrolimus cream 1% in HIV-positive patients with facial SD. METHODS: In a single-centre study, 21 HIV-infected patients with mild to severe SD were treated twice daily with pimecrolimus cream 1% for 14 days. Thereafter, treatment was discontinued and patients followed up for 5 weeks. Skin involvement at baseline and on days 7, 14, 21, 35 and 49 was assessed using a four-point clinical score and digital photography. MAIN OUTCOME MEASURES: Efficacy and safety of pimecrolimus cream 1% treatment and incidence of relapse in the follow-up phase. Results Marked improvement was seen in clinical parameters at day 7, with >or= 90% patients clear of symptoms at day 14. Relapse was observed at day 35 but signs were milder than at baseline. All patients responded to therapy, despite their immunological status. Pimecrolimus did not alter CD4(+) and CD8(+) T-cell counts or viral load during the treatment period. CONCLUSION: Pimecrolimus cream represents a new, effective therapeutic option for facial SD in HIV patients.     

In-vitro maturation of human germinal vesicle stage oocytes: role of cumulus cells and epidermal growth factor in the culture medium

In-vitro maturation (IVM) of oocytes is a promising technique to reduce the costs and avert the side-effects of gonadotrophin stimulation for in-vitro fertilization (IVF). The pregnancy rates from oocytes matured in vitro are much lower than those of in-vivo stimulation cycles indicating that optimization of IVM remains a challenge. Therefore, we investigated the effect of supplementation of the medium with gonadotrophins, oestradiol and epidermal growth factor (EGF) and the effect of retaining or removing the cumulus cells on nuclear and cytoplasmic maturation of immature oocytes. Human germinal vesicle (GV) oocytes obtained after gonadotrophin stimulation for intracytoplasmic sperm injection (ICSI) were cultured in a complex defined medium either supplemented with gonadotrophins, oestradiol and physiological concentrations of EGF (2 ng/ml) or gonadotrophins and oestradiol alone. The cumulus cells were either removed or kept intact. In GV stage oocytes cultured without cumulus (group I) significantly more oocytes reached the metaphase II (MII) stage at 30 h in media supplemented with EGF (64.3 versus 33.9%, P < 0.003). For oocytes cultured with intact cumulus (group II), more oocytes reached MII at 30 h than in group I, but there was no difference in medium with or without EGF supplementation (81.8 and 79.8% respectively). Cytoplasmic maturation of MII oocytes was judged from their capability to activate and fertilize after ICSI. In group I, the rates of activation and normal fertilization were similar. However, in group II, significantly more oocytes underwent normal fertilization in the EGF-supplemented than the unsupplemented group (71.7 versus 45.6%, P < 0.05). The cleavage rates of the fertilized oocytes were similar in the sibling oocyte subgroups cultured with or without EGF supplementation, but the overall cleavage rates were higher in cumulus-intact compared to cumulus-denuded oocytes (88.9 versus 47.8%, P < 0.001). Thus, supplementation of the maturation medium with EGF and maintenance of the cumulus during culture improve the nuclear and cytoplasmic maturation of human oocytes in vitro.
