Mycobacterium marinum infection of the hand and wrist. Results of conservative treatment in twenty-four cases

Inadequate débridement, extensive scarring, and breakdown of the wound have been commonly encountered after surgical débridement has been employed as the initial treatment of infection with Mycobacterium marinum involving the deep structures of the hand. Because of our disappointment with the results of this form of treatment, from 1982 to 1986 we treated twenty-four patients who had such an infection with rifampicin and ethambutol after a diagnostic biopsy was done. Surgical treatment was deferred until it was determined that the infection had not been controlled by the chemotherapy. The clinical outcome for these patients could be divided into three patterns: eleven patients (Group I) had a good result with no complications, three patients (Group II) had delayed healing of the wound, and ten patients (Group III) did not have a good response to conservative treatment and required one or more surgical débridements. Complications were sometimes associated with use of the drugs, and loss of visual acuity was a concern in three patients. In twenty-one (87 per cent) of the patients, at follow-up the function of the treated hand was equal to that of the other hand. Persistent pain, a discharging sinus, and previous local injection of steroids were unfavorable prognostic factors. If these factors are present, surgical débridement is advised.     

Gestational diabetes mellitus in women in the fourth decade--is treatment worthwhile?

AIM: To examine the influence of diet-treated gestational diabetes mellitus on the obstetric performance of mothers aged 40 and above. METHOD: We reviewed the delivery records of 205 mothers aged 40 and above who delivered over a 3-year period. A 75-gram oral glucose tolerance test was performed in all cases and 64 (31.2%) (18 primiparas and 46 multiparas) had gestational diabetes mellitus. This affected group of patients was compared with a group of age- and parity-matched controls to determine the impact of gestational diabetes mellitus on the obstetric outcome. RESULTS: There was no difference in the maternal anthropometric parameters, antenatal complications, or labor performance. While no statistically significant difference was found in the infant anthropometric parameters, the study group had a lower incidence (p = 0.043) of large-for-gestational age infants. CONCLUSION: Our findings suggested the adverse effects of gestational diabetes mellitus on pregnancy outcome were confounded to a large extent by other factors such as age, parity, and obesity. Once compared with matched controls, gestational diabetes mellitus that can be successfully treated with diet therapy probably had minimal adverse effect on the obstetric outcome. Furthermore, diet treatment can probably reverse the effect of advanced maternal age on infant size in these women.     

Treatment of recurrent miscarriage and antiphospholipid syndrome with low-dose enoxaparin and aspirin

The aim of this retrospective, observational study was to determine the impact of low-dose enoxaparin (20 mg) in conjunction with low-dose aspirin on the pregnancy outcome of women with antiphospholipid syndrome and recurrent miscarriage. The study was conducted in a tertiary referral teaching hospital. A total of 35 women with antiphospholipid syndrome were treated with low-dose enoxaparin and aspirin as soon as pregnancy was confirmed. The outcome of pregnancy was analysed. The miscarriage rate was 7/35 (20%) whereas the live birth rate was 28/35 (80%). In conclusion, low-dose (20 mg) enoxaparin in conjunction with low-dose aspirin treatment produced encouraging results. The findings in this study suggest that there is a case for randomized controlled trials to compare low-dose (20 mg) enoxaparin with higher doses.     

Pyoderma gangrenosum associated with erythroid hypoplasia

Pyoderma gangrenosum is most commonly associated with inflammatory bowel disease and rheumatoid arthritis, but it has been associated with various haematological malignancies. We describe its association with primary erythroid hypoplasia without thymoma in an 80 year old woman who presented with septicaemia complicating urinary tract infection. Spontaneous healing of an extensive lesion was observed.     

HIV-1, sexually transmitted infections, and sexual behavior trends among men who have sex with men in Lima, Peru

OBJECTIVE: To assess and estimate trends in HIV, sexually transmitted infections (STIs), and sexual behavior among men who have sex with men (MSM) in Lima, Peru. DESIGN: Second-generation HIV sentinel surveillance surveys conducted in 1996, 1998, 2000, and 2002. METHODS: Adult men reporting sex with at least 1 man during the previous year were eligible to participate. Sexual behavior and serum HIV-1 and syphilis antibodies were assessed. HIV seroincidence was estimated by a sensitive/less-sensitive enzyme immunoassay strategy. Rectal and pharyngeal swabs for Neisseria gonorrhoeae culture and a first-void urine sample for urethral leukocytes for presumptive diagnosis of urethritis were obtained. Herpes simplex virus 2 (HSV-2) antibodies were measured in 2002. RESULTS: Although HIV prevalence increased from 18.5% to 22.3% from 1996 through 2002, bacterial prevalence declined significantly for syphilis (16.0% to 12.4%), early syphilis (8.6% to 3.4%), and rectal gonorrhea (5.1% to 0.2%). High HIV seroincidence was estimated, with the lowest (4.8%) incidence in 1998. In 2002, HSV-2 seroprevalence was 51.0%. After adjustment for age, education, and self-reported sexual identity, our data suggest that a yearly increase by 6% in the prevalence of HIV occurred among MSM in Lima, with a corresponding decline in syphilis (by 9%), early syphilis (by 18%), and rectal gonorrhea (by 64%). Condom use during last sexual intercourse increased by 26% each year with the most recent male steady partner and, among non-sex workers, by 11% with the most recent casual partner. CONCLUSIONS: HIV continued to spread among MSM in Lima even when a decline in bacterial STIs and increase in condom use were estimated to occur. Intensification of medical and behavior prevention interventions is warranted for MSM in Peru.

Structuring a safer donor-replacement program

BACKGROUND: Replacement donors are more likely than volunteer donors to have positive or abnormal tests for transfusion-transmissible disease. In an effort to increase the donor pool, workers sought to identify a safer replacement-donor subgroup that may be acceptable for routine donations. STUDY DESIGN AND METHODS: In a retrospective review and cohort study, the replacement-donor effect was separated from the new- donor effect. The relative effect the replacement donor has on the risk of transfusion-transmissible diseases, donor retention, and frequency of returning donations was then quantified by comparison against the effect of repeat volunteer donors. RESULTS: The replacement donor had 3.1 times the risk and 0.72 times the donor retention rate and made 0.81 times as many returning donations as the repeat volunteer donor. The figures for the new-donor effect were similar. The two risks were additive, making a new replacement donor particularly hazardous. If replacement donations only from repeat replacement donors were considered, the donor risk and the number of donations per returning donor were made comparable to those for the general (combined) volunteer donor. CONCLUSION: The negative effect of the replacement donor is similar in magnitude to that of the new volunteer donor. A replacement-donation program targeting repeat replacement donors has an acceptable risk profile and may be a valuable adjunct to the collection of blood from general volunteer donors.
