Infantile Digital Fibroma Treated With Mohs Micrographic Surgery

BACKGROUND: Infantile digital fibroma (IDF) is a rare benign fibrous tumor of childhood that frequently recurs despite local excision. Conservative, nonsurgical management may result in regression and/or joint deformity. OBJECTIVE: To describe the histologic features of IDF and discuss a case excised using Mohs micrographic surgery (MMS). METHODS: Case report and review of the clinical, histologic, and ultrastructural features. RESULTS: Characteristic inclusion bodies of actin were identified with hematoxylin and eosin, Masson's trichrome, and rapid actin immunostain. The tumor was debulked and the majority was removed after one stage of MMS, except where the deep margin approached the joint space. The defect healed by secondary intention. At 2 years the patient had no recurrence or functional joint deformity. CONCLUSION: MMS is a surgical treatment option for IDF.     

Alemtuzumab (CAMPATH 1H) Induction Therapy in Cadaveric Kidney Transplantation—Efficacy and Safety at Five Years

Alemtuzumab is a powerful lymphocyte depleting antibody currently being evaluated in solid organ transplantation. This paper describes 5-year results of a single center study of alemtuzumab as induction in renal transplantation. Thirty-three renal transplant recipients received 20 mg alemtuzumab on day 0 and 1, followed by half-dose cyclosporin monotherapy (trough concentration 75-125 ng/mL) from day 3. They were compared in a retrospective contemporaneous-controlled manner with 66 kidney transplant recipients transplanted in the same period and center who received conventional immunosuppression with cyclosporin, azathioprine and prednisolone. In the alemtuzumab group 12% of recipients died compared to 17% in the control group (p = 0.48); likewise graft loss was similar in both groups (21% vs. 26%, respectively, p = 0.58). Incidence of acute rejection was also comparable at 5 years (31.5% vs. 33.6%), although the pattern of rejection was different with 14% patients in the alemtuzumab group experiencing rejection over 1 year post-transplant compared to none in the control group. There was no significant difference between groups in terms of infection or serious adverse events. While acknowledging the limitations of a relatively small single-center study, results suggest that alemtuzumab induction allowed satisfactory long-term patient and graft survival equivalent to that seen with standard triple immunosuppression, while avoiding steroid therapy.     

Smoking and coffee intake following alcohol withdrawal in alcoholic inpatients

The aim of this study was to assess alcoholic inpatients' smoking and coffee intake variation following withdrawal. Only moderate smokers (less than 30 cigarettes/day) showed a significant increase of cigarette consumption after alcohol withdrawal. However, their urinary cotinine level did not vary, suggesting a behavioral, and not biological, compensation through smoking following alcohol withdrawal. Heavy smokers (30 cigarettes/day or more) showed no significant clinical or biological variation of smoking behavior. Coffee consumption increased after alcohol withdrawal in all patients, irrespective of smoking habits.     

APPROACHES TO PROMOTING MORE WIDESPREAD PARTICIPATION IN PHYSICAL ACTIVITY

Exercise is associated with a reduced risk of coronary heart disease, has beneficial effects on cardiovascular risk factors, and has other health benefits. No more than 10 per cent to 20 per cent of adults in Australia and other developed countries participate in regular vigorous physical activity, while over 65 per cent of Australian adults are almost totally sedentary. Survey data from the U.S.A. suggest that levels of participation in jogging and walking have increased in the past 10 years but that the proportion of people who take no deliberate exercise has also increased. Large-scale community interventions to promote exercising have not been subject to rigorous evaluation and it is difficult to reach any firm conclusions about the effects of exercise promotion. However, it is possible to identify some of the factors which may influence exercise participation, and there is information from trials of large-scale, multifactorial interventions to reduce cardiovascular risk which provides some helpful guidelines about how it may be useful to proceed. Approaches to increasing levels of exercise participation should emphasise community-based efforts which provide appropriate settings and social support for exercising, making exercise a more appealing and accessible option for large numbers of people; the use of mass media for community education about exercising should be co-ordinated carefully with specific community activities. Personalized fitness instruction, groups and classes should place more emphasis on exercise as a pattern of behaviour to be integrated into a person's way of life and maintained over time; and there is the potential for more widespread and systematic use of self-instructional exercise materials to assist people who wish to exercise independently. Because there exist only limited local research findings and work in other countries does not yet provide conclusive information, research and development priorities for these areas are suggested.
