Colchicine for acute gout.

BACKGROUND: Gout is one of the most common rheumatic diseases worldwide. Colchicine is regarded as beneficial in the treatment of acute gout, but has a high frequency of gastrointestinal adverse events. OBJECTIVES: To evaluate the efficacy and safety of colchicine for relief of the signs and symptoms of acute gouty arthritis, compared to placebo and other treatment interventions. SEARCH STRATEGY: We searched the following electronic databases to March 2006: Cochrane Central Register of Controlled Trials (CENTRAL, Issue 1, 2006), MEDLINE (from 1966), EMBASE (from 1980), CINAHL (from 1982), AMED (from 1985), Web of Science (from 1945) and Current Controlled Trials. SELECTION CRITERIA: Published randomised controlled trials (RCTs) and controlled clinical trials evaluating symptom relief and adverse outcomes of colchicine therapy in acute gout were considered for this review. DATA COLLECTION AND ANALYSIS: Two reviewers independently screened search results for inclusion, collected the data in a standardized form and assessed the methodological quality of the trial using validated criteria. Results for continuous outcome measures were expressed as weighted mean differences. Dichotomous outcome measures were pooled using relative risk. The number needed to treat was calculated for significant outcomes. MAIN RESULTS: One RCT (N=43) comparing colchicine to placebo for the treatment of acute gout was included in this review. The results favour the use of colchicine over placebo with an absolute reduction of 34% for pain and a 30% reduction in clinical symptoms such as tenderness on palpation, swelling, redness, and pain. The number needed to treat (NNT) with colchicine versus placebo to reduce pain was 3 and the NNT to reduce clinical symptoms was 2. All participants treated with colchicine experienced gastrointestinal side effects (diarrhea and/or vomiting) and the number needed to harm (NNH) with colchicine versus placebo was 1. No studies comparing colchicine to NSAIDs or other treatments such as corticosteroids or ACTH were identified. AUTHORS' CONCLUSIONS: Colchicine is an effective treatment for the reduction of pain and clinical symptoms in patients experiencing acute attacks of gout, although in the regimen studied its low benefit to toxicity ratio limits its usefulness. It should be used as a second line therapy when NSAIDs or corticosteroids are contraindicated or ineffective. More evidence is needed to compare the efficacy of colchicine to that of NSAIDs or corticosteroids, the current first line therapy for acute gout.

Nail involvement in pemphigus vulgaris.

BACKGROUND: Involvement of the nail unit in pemphigus vulgaris (PV) is thought to be rare. OBJECTIVES: To determine the frequency of nail changes among patients with PV. METHODS: Nail changes were recorded in patients with PV and were analysed retrospectively. Biopsies were taken from the nail bed and nail matrix for histological and immunofluorescence observations. Microscopic (potassium hydroxide) examination and fungal culture were performed. RESULTS: Nail changes were present in 30 of 64 (47%) patients with PV. Sixteen patients had onychomycosis and 14 had nail changes due to PV. These included onychomadesis, discoloration, deformity, onychorrhexis, onycholysis, subungual haemorrhage, subungual hyperkeratosis and paronychia. Onychomycosis affected fingernails and toenails, but changes due to PV occurred only in fingernails, most commonly on the thumb and index finger. No connection was found between the patient's occupation and nail involvement, and there was no correlation with the severity or duration of PV. In a control group of 64 patients of similar sex and age, only two had non-specific fingernail changes. CONCLUSIONS: Nail changes in PV may be more frequent than previously thought.

Gout: can management be improved?

Ongoing reviews of Cochrane collaboration show that there is still very little reliable information based on randomized controlled trials on which to base treatment decisions in acute and chronic gout. Recent studies have stressed that avoidance of factors contributing to development of gouty attacks such as diuretic therapy, weight gain, and alcohol consumption may lead to a decrease in gouty arthritis. Attention to minidose aspirin and its effect on serum uric acid levels was addressed. A low carbohydrate, high protein and unsaturated fat diet was recommended for gouty patients since they all enhance insulin sensitivity and therefore may promote a reduction in serum uric acid levels. Treatment of gout in transplant recipients brings into focus some of the issues regarding management of gout, because gout is a common problem among transplant patients.

How well have diagnostic tests and therapies for gout been evaluated?

The first descriptions of gout can be traced to the dawn of recorded medical history, yet a number of controversies and unanswered questions remain regarding diagnosis and treatment of gout. Questions can still be posed about the need for crystal identification of all cases, the utility of a 24-hour urine collection for uric acid, and even the difficulty of choosing a technique for measurement of uric acid. Some time has elapsed since Mesner stated in 1623, "Love and gout are incurable." How far have we come? How have we evaluated different treatments for gout? Ongoing reviews of the Cochrane collaboration show that there is still very little reliable information based on randomized controlled trials on which to base treatment decisions in acute and chronic gout.

Acute gouty arthritis is seasonal.

OBJECTIVE: Information regarding effect of weather conditions on gout is sparse. We conducted a study in the USA to examine whether gout is seasonal. METHODS: We reviewed synovial fluid (SF) analyses from our laboratory during 1990-1995 and identified 359 patients who had acute gouty attacks. All fluids of patients with acute gout had intracellular monosodium urate crystals and SF leukocyte counts > 2000/mm3 or more than 10 leukocytes per high power field (HPF). Retrospective chart review of all patients was performed to confirm a clinical picture of acute gout. A control group included 76 patients with acute pseudogout whose SF were analyzed during the same period and who had intracellular calcium pyrophosphate crystals and inflammatory leukocyte counts as in patients with gout. RESULTS: Acute gout was most common during the spring; n = 115 (32%). Ninety (25%) patients had acute gout attacks in the fall; 81 (23%) had acute attacks during the summer; 73 (20%) had acute attacks in the winter. One-way analysis of variance (ANOVA) was used to compare the overall frequency of acute gout during the months and seasons. Using ANOVA, there was no overall statistically significant difference in the incidence of gout per season (p = 0.07), although it approached statistical significance. Acute gouty attacks were more common in the spring compared with winter (p = 0.002) and summer (p = 0.015). There was a trend but no statistically significant difference compared with fall. Winter was the season in which the fewest acute gouty cases were seen, although it was not statistically significant. No seasonal difference was seen in the pseudogout group. There was no correlation between either mean monthly temperature or humidity and the incidence of acute gouty attacks. CONCLUSION: Acute gout attacks are significantly more common in the spring. No seasonal variation was seen in patients with acute pseudogout attacks.

Israeli dentists: a survey of infection control office practices and care of medically compromised patients.

A survey was conducted by interviewing a randomly selected sample of practicing dentists in Israel in 1991. The aim of this study was to evaluate methods of infection control in current use and to learn about the access to care for medically compromised patients. One hundred seventeen dentists were interviewed. This group represented a majority of graduates from Israeli schools (66). With respect to infection control, only 28% of the population surveyed routinely uses gloves, but 43% use steam autoclave, and 70% use dry-heat sterilization. A very high percentage (87%) took a verbal medical history, while a small minority (27%) had their patients fill out a written questionnaire. Only occasionally was the name of the patient's physician requested or recorded, implying a flaw in interprofessional communications. Only 26% of the dentists said they would treat patients with hepatitis and/or AIDS. Only about half the dentists accepted patients on chemotherapy or radiotherapy or those who were taking anticoagulant drugs. Physical access for dental patients in wheelchair or stretcher was markedly limited, with referral to regional hospitals the routine for these patients.
