Use of health-care services, work absenteeism, leisure-time physical activity, musculoskeletal symptoms and physical performance after vocationally oriented medical rehabilitation-description of the courses and a one-and-a-half-year follow-up study with farmers, loggers, police officers and hairdressers.

The aim of this study was to evaluate the effectiveness of vocationally oriented medical rehabilitation (VOMR) carried out in institutions with regard to the use of health-care services, work absenteeism, leisure-time physical activity, musculoskeletal symptoms and physical performance during 112 years of follow-up. The prospective cohort study consisted of 265 patients from four different occupational groups (loggers, hairdressers, police officers and female farmers) who took part in VOMR courses in three inhouse phases, financed by the Finnish Social Insurance Institution, and who had chronic musculoskeletal symptoms in their back and neck. The subjective physical and mental strain of work, subjective neck-shoulder and low-back pain, use of health-care services and leisure-time physical activity were assessed with a questionnaires. The muscle strength of the upper and lower extremities and trunk was determined and maximal VO2 was measured using the direct maximal bicycle ergometer test. The subjective physical and mental strain of work, subjective neck-shoulder and low-back pain and physical performance showed positive significant development and improvement. The changes in the use of health-care services and work absenteeism were minor or insignificant. The general finding was that the results from the second phase of the VOMR courses did not differ from those of the third phase. VOMR courses had a beneficial effect on physical performance and subjective pain caused by neck and back musculoskeletal diseases of farmers, loggers, police officers and hairdressers within 112 years of follow-up, but VOMR courses did not decreased the use of health-care services.

Ovulation inhibitors containing cyproterone acetate or desogestrel in the treatment of hyperandrogenic symptoms.

An open, randomized, multicenter study was carried out to compare two oral contraceptives as regards their therapeutic efficacy in androgenization symptoms such as acne, seborrhea and hirsutism in women. The preparations used were the combination of 2 mg cyproterone acetate (CPA) with 0.035 mg ethinyl estradiol (EE) (Diane 35, Schering AG, Berlin-West) and 0.150 mg desogestrel (DG) with 0.03 mg ethinyl estradiol (Marvelon, Organon, Oss, The Netherlands). The duration of therapy was 9 months. The combination of CPA-EE was used by 83 patients for 658 cycles and the combination of DG-EE by 79 women for 618 cycles. No pregnancy occurred under either therapy. Both preparations are well tolerated. However, some side-effects, such as reduced libido, nervousness and breast tenderness, were observed more frequently (p less than 0.05) in the DG-EE group than among the users of the CPA-EE combination. The therapeutic outcome was better in the CPA-EE group, especially in cases of facial acne (p less than 0.05). Seborrheic symptoms also responded better to the CPA-EE therapy. The results show that the CPA-EE combination is superior to the DG-EE combination in the treatment of acne and seborrhoea.

Normophasic preparation containing progestogen desogestrel and ethinylestradiol.

A Finnish multicenter study was carried out on 157 healthy fertile volunteers (2157 cycles) to evaluate an oral normophasic contraceptive preparation comprising 7 tablets of 0.050 ethinyl estradiol followed by 15 tablets of 0.050 mg ethinyl estradiol + 0.125 mg desogestrel. Bleeding patterns, side effects, liver function, and dropouts were recorded, as well as the development of the endometrium. No pregnancies occurred. Irregular bleeding (spotting and breakthrough bleeding) occurred in 12% of the 1st treatment cycle and in only 4% after 1 year's treatment. The most common side effects were nausea and headache. 17 women dropped out because of subjective side effects after 12 treatment cycles. No changes of any clinical importance were seen in mean body weight or liver function tests. Most of the endometrial biopsies showed a secretory pattern with mild hypoplasia. No hyperplastic or malignant changes were seen.
