RESUMO
Mechanical ventilation of patients with Duchenne muscular dystrophy continues to be a subject of study. The purpose was to estimate prevalence, incidence, mortality and use of mechanical ventilation in the total Duchenne muscular dystrophy population in Denmark between 1977 and 2001 and further, to reconstruct the introduction of mechanical ventilation to assess the role of the patient organization. Study objects were collected from five sources and verifiable cases identified. Negotiations between health authorities and the patient organization constituted main empirical data for the reconstruction. While overall incidence remained stable at 2.0 per 10(5), prevalence rose from 3.1 to 5.5 per 10(5), mortality fell from 4.7 to 2.6 per 100 years at risk and prevalence of Duchenne muscular dystrophy ventilator users rose from 0.9 to 43.4 per 100. We conclude that survival of Duchenne muscular dystrophy patients has increased and ventilator use is probably a main reason. The patient organization exercised a key role but acted upon preconditions created by other players.

We aimed at studying fracture risk in patients with Duchenne's muscular dystrophy (DMD), Becker's muscular dystrophy (BEMD), and spinal muscular atrophy type II and III (SMA II and III). A self-administered questionnaire was mailed to 293 patients with DMD, BEMD, SMA II or SMA III of which 229 returned the questionnaire. Each respondent was compared with an age- and gender-matched control subject. The mean age was 23.9 +/- 15.9 years for the patients and 23.3 +/- 16.5 years for the controls. There were significantly more fractures among patients than controls after the diagnosis was made (RR = 1.9), but not before. The patients had more fractures of the femurs, lower legs, and upper arms than the controls. Low energy fractures were more frequent in patients than controls (9% vs 0%). Many fractures in the femurs (40%), lower legs (35%), and feet and toes (44%) led to a permanent loss of function. Loss of ambulation was the major risk factor for fractures. In conclusion, fracture risk is increased in neuromuscular disease.

PIP: A report is presented of 69 women, aged-16-43, who used the sequential preparation Ovanon (mestranal and chlormadinone and mestranol combined). Serum concentration measurements were takem for various compounds after 1 and 3 months of oral contraceptive use. Total protein albumin and other serum globulin fractions and enzymes remained constant. There were decreases in the serum cholinesterase and serum alkaline phosphates after 3 months. An increase in the ceruloplasmine concentration was evident after the 1st month of oral contraceptive use. The increases and decreases reported here are less than in similar studies on the effect of combination preparations. The smaller fluctuation in the serum concentrations is attributed to the lower estrogen content of the sequential preparation.^ieng
