Reproducibility of Two Four-Point Clinical Severity Scores for Lateral Canthal Lines (Crow''s Feet)

BACKGROUND: Several clinical scoring systems have been used to evaluate the efficacy of botulinum toxin A in the treatment of hyperkinetic wrinkles. So far very few have been investigated for their reproducibility. OBJECTIVE: The aim of this study was to investigate the reproducibility of two clinical four-point scales for lateral canthal lines (crow's feet), at rest and at maximum smile. MATERIAL AND METHODS: Based on standardized photographs, a consensus atlas depicting the different severity grades [from 0 (none) to 3 (severe)] was developed. After training based on the atlas, 49 photographs at rest and 48 at maximum smile were graded by the same group of investigators on 2 consecutive days (n=9 on Day 1; n=8 on Day 2). The scores were compared for reproducibility using kappa statistics. RESULTS: Overall, reproducibility was good for both scales. Interobserver reproducibility showed an agreement of 0.6 at rest and 0.58 at maximum smile (unweighted kappa). Intraobserver reproducibility showed an agreement between 0.47 and 0.86 at rest and between 0.62 and 0.81 at maximum smile (unweighted kappa). Using weighted kappa analysis, the agreement ranged between 0.63 and 0.91 at rest and between 0.71 and 0.85 at maximum smile. CONCLUSION: The clinical scales using scores of 0 to 3 for crow's feet, both at rest and at maximum smile, show a good inter- and intraobserver reproducibility. The use of these scores in clinical trials can be recommended.     

Effect of metoprolol on death and cardiac events during a 2-year period after coronary artery bypass grafting

PURPOSE: To evaluate the effect of long-term treatment with metoprololafter coronary bypass grafting on death and cardiac events. METHODS: Patients in western Sweden on whom coronary artery bypass graftingwas performed between June 1988 and June 1991 were evaluatedfor inclusion during the first 3 weeks after surgery. Majorexclusion criteria were age >75 years, concomitant valvesurgery, traditional contraindications to beta-blockers andunwillingness to participate. Patients were randomized in adouble-blind fashion to 100 mg of metoprolollplacebo daily for2 weeks and thereafter 200 mg daily for 2 years. RESULTS: Of 2365 patients who were operated on, 967 were randomized toeither metoprolol (n=480) or placebo (n=487). Primary end points(death, non-fatal myocardial infarction, unstable angina pectoris,need for coronary artery bypass grafting or percutaneous transluminalangioplasty), were reached by 42 patients in the metoprololgroup (8·8%) as compared with 39 in the placebo group(8·0%) (P=0·73). Of all the patients randomizedto metoprolol, 34% withdrew from blind treatment prematurelycompared with 44% for placebo (P<0·01) CONCLUSION: Prophylactic treatment with metoprolol over a 2-year periodafter coronary artery bypass grafting did not reduce death orthe development of cardiac events. However, the 95% confidencelimits ranged from the possibility of a 30% reduction in eventsto a 68% increase in events if patients were treated with metoprololas compared with placebo.     

Endocrine therapy with or without radical prostatectomy for T1b-T3N0M0 prostate cancer

BACKGROUND: We retrospectively compared the 5-year survival rates of T1b-T3N0M0 prostate cancer patients treated either by endocrine therapy plus radical prostatectomy or endocrine therapy alone. METHODS: Clinical T1b-T3N0M0 prostate cancer patients were enrolled at 104 institutions in Japan. They were assigned to study 1 (n = 176), if they were indicated to prostatectomy, if not indicated, they were assigned to study 2 (n = 151). The indication of prostatectomy was based on the clinical judgement of physicians and/or patients. Those assigned to study 1 underwent prostatectomy and adjuvant endocrine therapy with or without preoperative androgen deprivation. Those assigned to study 2 were treated with leuprorelin acetate with or without chlormadinone acetate. They were followed-up every 3 months until death or for 5 years and over. RESULTS: Those assigned to study 1 were younger (mean age 67.2 vs 75.7 years), less advanced in clinical stage, and had lower prostate specific antigen levels (mean 43.8 vs 103.6 ng/mL). Death for any reason was observed less frequently in study 1 (n = 29, 16%) than study 2 (n = 50, 33%), and the 5-year overall survival rate was higher in study 1 (87 vs. 68%). However, prostate cancer deaths were comparatively seldom (9% in study 1 and 7% in study 2), resulting in the identical 5-year cause specific survival rate in both study groups (91%). In both study groups the overall survival was almost equal to the natural survival of age-matched men. CONCLUSIONS: Endocrine therapy offers a reasonable survival rate in T1b-T3 prostate cancer patients within a 5-year follow-up. Observation will be extended to determine 10-year outcomes.     

General Practitioners' Use of Health Education Material. Results From a Nationwide Survey in Denmark in 1991

In November 1991 69% of a random sample of 998 Danish generalpractitioners (GPs) participated in a survey by anonymouslyfilling in a mailed questionnaire concerning the way in whichthey use health education in their practices. Among the participatingGPs, 97% used health education material. The study showed differencesin attitudes towards and use of health education material. Thematerial most often used by GPs at the consultation concerneddiet/overweight, allergy and pregnancy. Pamphlets and postersin the waiting room mainly dealt with vaccination, alcohol andsmoking. The female practitioners were generally most sympatheticto the use of health education material, but they are also thosemost critical, of material advertising for medicine. The malepractitioners thought that there was too much material and thatthey did not have enough time to use it.

SKALP/elafin gene polymorphisms are not associated with pustular forms of psoriasis

Psoriasis is a multifactorial skin disease characterised by epidermal abnormalities and infiltration by lymphocytes and polymorphonuclear leukocytes (PMN). Skin-derived antileukoproteinase (SKALP), also known as elafin, is a potent inhibitor of human leukocyte elastase and proteinase 3, two PMN-derived proteinases implicated in tissue destruction and leukocyte migration. We have shown that, at least at the protein level, SKALP is significantly decreased in lesional skin of patients with pustular psoriasis compared with plaque-type psoriasis. This finding raised the possibility that SKALP could be one of the candidate genes for pustular forms of psoriasis. We therefore performed single strand conformation polymorphism (SSCP) analysis on the SKALP gene to screen for mutations/polymorphisms in the exons of 30 patients with plaque-type psoriasis, 15 patients with pustular psoriasis and 48 healthy controls. In exon 1 a polymorphism was detected at position + 43 relative to the translation start site, resulting in a substitution of threonine for alanine in the signal peptide. In the promoter region a dinucleotide repeat polymorphism was identified. Both polymorphisms were not associated with pustular psoriasis, or psoriasis in general. Our data indicate that the decrease in SKALP activity in pustular psoriasis is not caused by mutations in the coding region of the gene, and that there is no allelic association between pustular psoriasis and SKALP gene polymorphisms.     

HLA-DR4 SUBTYPE AND -B ALLELES IN DQB1*0302-POSITIVE HAPLOTYPES ASSOCIATED WITH IDDM

We determined the distribution of DR4 subtypes in 309 DQB1*0302-positive haplotypes found in insulin-dependent diabetes mellitus (IDDM) patients and 70 control haplotypes present only in healthy family members. An increased frequency of DRB1*0401 allele (74.4% vs. 55.7%, P = 0.003) and a decrease of DRB1*0404 allele (23.6% vs. 40.0%, P = 0.0064) was revealed. A further analysis of extended haplotypes demonstrated strong linkages between various B alleles and DRB1*04 subtypes. HLA-B39 was more frequent in DRB1*0404–DQB1*0302-positive IDDM haplotypes compared with control ones (37.0% vs. 14.3%, P = 0.049), suggesting an involvement of the region telomeric to HLA-DRB1 in the susceptibility to IDDM.
