Interventions for isolated diaphyseal fractures of the ulna in adults.

BACKGROUND: Isolated fractures of the shaft of the ulna, which are often sustained when the forearm is raised to shield against a blow, are generally treated on an out-patient basis. OBJECTIVES: To assess the effects of various forms of treatment for isolated fractures of the ulnar shaft in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group specialised register (November 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2003), MEDLINE (1966 to November week 2 2003), EMBASE (1981 to 2003 week 51) and CINAHL (1982 to December week 2 2003), Current Controlled Trials (accessed November 2003), the UK National Research Register (up to Issue 4, 2003 ), various conference proceedings and bibliographies of relevant articles. Date of the most recent search: December 2003. SELECTION CRITERIA: Randomised or quasi-randomised trials of conservative and surgical treatment of isolated fractures of the ulnar shaft in adults. Excluded were fractures of the proximal ulna and Monteggia fracture dislocations. DATA COLLECTION AND ANALYSIS: Independent quality assessment and data extraction were performed by the reviewers. Requests for more information were sent to trialists. Given the limited and generally poor quality evidence available, quantitative analysis was kept to a minimum. MAIN RESULTS: One new trial comparing two types of plates used for the surgical fixation of these fractures was included in the fifth update of this review. Thus there are now three trials, involving a total of 135 patients. All three trials were methodologically flawed, particularly the two trials of conservative treatment. One of these compared short arm pre-fabricated functional braces with long arm plaster casts. There was no statistically significant difference in the time it took for fracture union. Patient satisfaction and return to work were better in the brace group. The other, a quasi-randomised trial, compared Ace Wrap elastic bandage, short arm plaster cast and long arm plaster cast. The large loss to follow-up in this trial makes any data analysis tentative. However the need for replacement of the Ace wrap by other methods due to pain does indicate the potential for a serious problem with this intervention. There were no statistically significant differences in anatomical or functional outcomes nor complications between the two plate groups in the surgical trial. REVIEWERS' CONCLUSIONS: There is insufficient evidence from randomised trials to determine which method of treatment is the most appropriate for isolated fractures of the ulnar shaft in adults. There is a need to establish the incidence of this injury and the outcome and associated costs of the various forms of treatment. Well designed randomised trials of current forms of conservative treatment are recommended.

OBJECTIVES: To assess the effects of various forms of treatment for isolated fractures of the ulnar shaft in adults. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group's specialised register (December 2000), the Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 2000), MEDLINE (1966 to December 2000), EMBASE (1981 to December 2000), CINAHL (1982 to December 2000), and bibliographies of trial reports.

Requests for more information were sent to trialists. Given the limited and poor quality evidence available, quantitative analysis was kept to a minimum. MAIN RESULTS: In the second update of this review, the only newly identified trial was excluded. Thus, as before, two small trials of conservative treatment, involving a total of 106 patients were included in this review. Both trials were of poor quality. One randomised trial compared short arm pre-fabricated functional braces with long arm plaster casts. There was no statistically significant difference in the time it took for fracture union. Patient satisfaction and return to work were better in the brace group. The other quasi-randomised trial compared Ace Wrap elastic bandage, short arm plaster cast and long arm plaster cast.

Fluconazole therapy of oropharyngeal candidiasis in a patient with multiple endocrine failure does not correlate with Candida albicans susceptibility to fluconazole in vitro.

We report a case of oropharyngeal and oesophageal candidiasis in a 23-year-old man with endocrinopathy syndrome. Multiple episodes of infection were treated with topical miconazole, oral ketoconazole (200 mg daily) or oral fluconazole (50 mg daily) over a period of 7 years. The final episode failed to respond to ketoconazole (200 mg daily) or fluconazole (200 mg daily), but was treated successfully by increasing the fluconazole dose to 400 mg daily for 6 months. The patient was maintained on fluconazole 200 mg daily without relapse. Serial Candida albicans isolates from the oral cavity were clonally related by RFLP analyses of genomic DNA, and were resistant to fluconazole, ketoconazole and itraconazole in vitro. We conclude that fluconazole 400 mg daily is effective against oropharyngeal and oesophageal candidiasis in a patient with endocrinopathy syndrome, despite the infecting Candida albicans strains being resistant to azole antifungals in vitro.

Rings and watches: should they be removed prior to operative dental procedures?

OBJECTIVES: There is no clear evidence to support the recommendation that rings and watches should be removed prior to operative dental procedures. The aim of this study was to measure and identify the bacteria isolated from the skin under rings and watches worn by a group of dental surgeons and to compare the results with a group of non-clinical staff. METHODS: Forty volunteers participated in the study; of these 20 were dental surgeons and 20 were non-clinical staff. Four skin sites were sampled for each volunteer; the skin directly under the ring and on the same finger of the other hand and the skin under the watch face and wrist of the control hand. Bacteria on the swabs were dispersed and inoculated onto plates, which were incubated aerobically for 24 h at 37 degrees C. RESULTS: In both groups of volunteers there was a significantly greater number of bacteria isolated from under rings and watches compared with control sites. Few qualitative differences were found between the microflora found on the skin under rings and watches in the two volunteer groups. CONCLUSIONS: The bacterial flora isolated from volunteers do not commonly cause oral infections but could pose a threat to the immunocompromised patient, particularly in the event of gloves becoming torn or perforated. Effective hand disinfection is difficult to achieve if ring and watches are not removed; they should therefore be removed prior to hand disinfection and donning of gloves.

Relation between mouth and haematogenous infection in total joint replacements.

OBJECTIVE: To investigate the source of infections associated with orthopaedic prostheses. DESIGN: Analysis of four infections of prosthetic joints with case records; minimum inhibitory and minimum bactericidal concentrations and sodium dodecylsulphate polyacrylamide gel electrophoresis of the cell wall polypeptides of the Streptococcus sanguis isolates from the mouth and infected prostheses; examination of the patients' mouths for periodontal disease and caries. SUBJECTS: Four adults (three men) aged 58-83. RESULTS: For each patient the strain of S sanguis isolated from the mouth was indistinguishable from that isolated from the prosthesis. All patients had severe periodontal disease and caries. CONCLUSIONS: The mouth was probably the source of bacterial infection in the prosthetic joints of these patients; the route of infection was possibly haematogenous. Incipient oral infection should be treated before joint replacement, and oral health should be maintained indefinitely.

Antibiotic-resistant oral streptococci in dental patients susceptible to infective endocarditis.

The aim of this study was to determine the incidence of amoxycillin and erythromycin resistance in oral streptococci in patients at risk from infective endocarditis. Samples of gingival crevicular flora were taken from 65 patients at the site of dental treatment, prior to the prophylactic administration of amoxycillin (54 patients) or erythromycin (11 patients). Samples were also taken from 65 dental patients who were not considered to be at risk from infective endocarditis. No isolate had a minimum inhibitory concentration (MIC) of amoxycillin greater than 24 mg/L. However, erythromycin-resistant oral streptococci with MIC values greater than 3.5 mg/L were isolated from 22% of patients receiving amoxycillin prophylaxis, 9% of patients receiving amoxycillin prophylaxis, 9% of patients given erythromycin prophylaxis and 9% of patients not at risk from infective endocarditis. The antibiotic-resistant streptococci comprised mainly Streptococcus sanguis biotype II, although S. sanguis biotype I, S. mitis and S. salivarius were also frequently recovered.
