Comparative clinical trial of fenticonazole ovule (600 mg) versus clotrimazole vaginal tablet (500 mg) in the treatment of symptomatic vaginal candidiasis

A multi-centre, randomized, single-blind, parallel-group clinical trial was undertaken in 50 patients (26 fenticonazole, 24 clotrimazole) with symptomatic vaginal candidiasis to compare the antifungal efficacy and tolerability of single-dose intra-vaginal treatment with a fenticonazole ovule (600 mg) or a clotrimazole vaginal tablet (500 mg). Assessment was by laboratory mycological investigation and symptomatic assessments for a period of 3 weeks from the day of treatment. Of the 50 patients, 43 (23 fenticonazole, 20 clotrimazole) returned for assessment 1 week after drug administration and 32 (17 fenticonazole, 15 clotrimazole) were re-assessed 3 weeks after drug administration. Both treatments resulted in very similar and highly significant improvements in symptoms, associated with disappearance of detectable Candida in approximately 70% of patients. There were no significant differences between treatments and no appreciable incidence of relapse during the 3-week period of observation. At the end of this period, 10 (59%) of 17 fenticonazole patients were totally disease-free, as compared with 10 (67%) of 15 patients after clotrimazole treatment. The cure rate observed was somewhat less than that previously seen when intra-vaginal cream formulations of the same two drugs were given on a multiple-dose basis. Both drugs were very well tolerated, with no reports of appreciable local or systemic adverse reactions to either drug.     

Acetabular preparation in cementless revision total hip arthroplasty

The rationale for and experience with the use of a hemispherical, cementless, microporous socket (Harris-Galante prosthesis) are presented as an approach to acetabular revision arthroplasty. Advantages are noted in preservation of existing bone, ease of rigid fixation, and bone grafting with either lyophylized particle allograft or autograft. The early results of a series of 75 sockets show no loss of fixation, mild to major resorption of non-contained bone graft, and favorable roentgenographic appearance of contained bone graft. In bone-grafted regions, a high percentage of lucencies at the graft-porous interface implies a lack of bone ingrowth. The authors were unable to characterize any roentgenographic behavioral differences between allograft or autograft. The approach is successful in severely deficient acetabulae, especially of the Type III combined cavitary and segmental medial wall deficiency.     

Platelet alpha granule secretion in cerebral ischemia: effect of short and long term low dose aspirin treatment

The effect of short and long-term therapy with aspirin (50 mg/day) on platelet alpha granule secretion was studied in 11 healthy controls and 57 patients suffering from transient cerebral ischemic attacks (TIA) with and without accompanying diabetes and hypertension. Plasma levels of beta-thromboglobulin (beta-TG) and platelet factor 4 (PF 4) were measured as indicators of platelet alpha granule secretion. beta-TG and PF 4 levels were increased following cerebral ischemia. Aspirin treatment failed to suppress plasma levels of both proteins when measured a month and then a year after initiation of treatment. Therefore, these proteins may be poor indicators of platelet inhibition by aspirin.     

Role of topical lignocaine during carotid endarterectomy.

Forty carotid endarterectomies were undertaken in 34 patients. Operations were prospectively randomized to periarterial application of either 1 per cent lignocaine (n = 19) or normal saline (n = 21), and detailed measurements taken of intraoperative pulse rate and blood pressure. Patients receiving lignocaine demonstrated a lower pulse rate, and lower systolic and mean blood pressures than those receiving placebo, with significance in relation to clamp application and shunt removal (P < 0.05). It was particularly noticeable that patients receiving lignocaine demonstrated less intraoperative variation in pulse rate and blood pressure. Topical lignocaine stabilizes pulse rate and blood pressure during carotid endarterectomy.     

Perineal exposure to talc and ovarian cancer risk.

OBJECTIVE: We sought to determine whether the use of talc in genital hygiene increases the risk for epithelial ovarian cancer. METHODS: We interviewed 235 white women diagnosed with epithelial ovarian cancer between 1984-1987 at ten Boston metropolitan area hospitals and 239 population-based controls of similar race, age, and residence. RESULTS: Overall, 49% of cases and 39% of controls reported exposure to talc, via direct application to the perineum or to undergarments, sanitary napkins, or diaphragms, which yielded a 1.5 odds ratio (OR) for ovarian cancer (95% confidence interval [CI] 1.0-2.1). Among women with perineal exposure to talc, the risk was significantly elevated in the subgroups of women who applied it: 1) directly as a body powder (OR 1.7, 95% CI 1.1-2.7), 2) on a daily basis (OR 1.8, 95% CI 1.1-3.0), and 3) for more than 10 years (OR 1.6, 95% CI 1.0-2.7). The greatest ovarian cancer risk associated with perineal talc use was observed in the subgroup of women estimated to have made more than 10,000 applications during years when they were ovulating and had an intact genital tract (OR 2.8, 95% CI 1.4-5.4); however, this exposure was found in only 14% of the women with ovarian cancer. CONCLUSIONS: These data support the concept that a life-time pattern of perineal talc use may increase the risk for epithelial ovarian cancer but is unlikely to be the etiology for the majority of epithelial ovarian cancers.     

Prolonged deterioration of ischemic brain energy metabolism and acidosis associated with hyperglycemia: human cerebral infarction studied by serial 31P NMR spectroscopy

We report on a patient with a large ischemic hemispherical stroke studied serially by 31P nuclear magnetic resonance spectroscopy. Persistent hyperglycemia was associated with prolonged acidosis in ischemic brain and failure of high-energy phosphate metabolism to recover. These in vivo human data support the concept that hyperglycemia adversely affects ischemic brain metabolism, pH, and clinical outcome.
