The treatment of somatization: teaching techniques of reattribution.

Patients commonly present to general practitioners with somatic symptoms for which no adequate physical cause can be found, which are accompanied by the symptoms of an anxiety state or a depressive illness. These illnesses pose a major public health problem, but little is known about optimal management. A three stage model is proposed to encourage patients to reattribute these symptoms, and relate them to psychosocial problems. These stages are; feeling understood; changing the agenda; and making the link. A videotaped learning package is described suitable for use with vocational trainees in general practice, consisting of demonstrations of component parts of the model followed by micro-teaching, as a preliminary to video-feedback of actual interviews with such patients.

Skin collagen changes in post-menopausal women receiving oestradiol gel.

Sixteen post-menopausal women who had never previously received any hormonal treatment applied Oestrogel cream 1.5 mg/day percutaneously for 1 yr. Skin biopsies were taken from the abdomen and from the lateral aspect of the thigh at 0, 3, 6 and 12 mth, and the changes in skin collagen content were noted. The abdominal skin collagen content increased significantly (P less than 0.001) over the 1-yr treatment period. The thigh skin collagen content also increased, but did not reach significant levels. There was a strong correlation between the change in skin collagen content (in both the abdomen and the thigh) and the original skin collagen content, indicating that the change in collagen content in response to oestrogen therapy is dependent on the original level. There is no further increase once an 'optimum' skin collagen level has been reached.

Decline in skin collagen content and metacarpal index after the menopause and its prevention with sex hormone replacement.

The thigh skin collagen content and the metacarpal index were measured in 69 untreated postmenopausal women and in 37 postmenopausal women who had been receiving oestradiol and testosterone implants for 2-10 years. There was a significant positive correlation between the skin collagen content and the metacarpal index in both groups of patients. In the untreated group, there was a statistically significant decrease both in the thigh skin collagen content and in the metacarpal index with the years since the menopause. This decrease was preventable in women who were on sex hormone replacement therapy.

The effects of norethisterone in postmenopausal women on oestrogen replacement therapy: a model for the premenstrual syndrome.

The influence of norethisterone on mood and behaviour was investigated in prospective placebo-controlled study in 58 postmenopausal hysterectomized women who were being treated with subcutaneous oestradiol and testosterone implants. Norethisterone, 2.5 or 5 mg daily, was given for 7 days and a placebo for two periods of 7 days. Psychological, behavioural and physical variables were assessed using the Menstrual Distress Questionnaire. There were widespread adverse effects which were dose-related. Significant changes in five of the eight symptom complexes studied (pain, concentration, behavioural change, water retention and negative affect) were found with 5 mg/day of the progestogen. The symptoms were similar to the typical complaints of the premenstrual syndrome, such that a combination of oestradiol and testosterone implants with cyclical oral norethisterone appears to be a model for this condition. The dose of this progestogen should therefore be the minimum to achieve the desired therapeutic effect.

Endometrial and menstrual response to subcutaneous oestradiol and testosterone implants and continuous oral progestogen therapy in post-menopausal women.

A regimen of subcutaneous implants of oestradiol and testosterone in combination with continuous oral norethisterone (0.35mg to 5mg daily) was used to treat 71 non-hysterectomised post-menopausal women for up to 30 mth in an attempt to avoid the withdrawal periods associated with conventional cyclical therapy, while at the same time protecting the endometrium from oestrogenic overstimulation. Amenorrhoea, defined as no vaginal bleeding for at least 3 mth, occurred immediately in 5.4-55.6% of women, the percentage depending on the daily dose of the progestogen. In those women who bled, the dose of norethisterone was adjusted at 3-mth intervals. Despite this protocol, only 51.0% of the patients were amenorrhoeic after 6 mth, and 63.2% after 1 yr. Although eight women did develop amenorrhoea for 12-27 mth, there was a high drop-out rate by the others, mainly because of unacceptable irregular bleeding. Irrespective of the bleeding pattern, endometrial biopsies 6 mth after treatment revealed endometrial atrophy. It is concluded that this form of therapy is inferior to oral continuous combined hormone replacement where amenorrhoea can almost invariably be achieved.

Amenorrhea and endometrial atrophy with continuous oral estrogen and progestogen therapy in postmenopausal women.

An oral regimen of continuous conjugated equine estrogens (Premarin 0.625 or 1.25 mg daily) and low-dose progestogen (Norethisterone 0.35 to 2.1 mg daily) have been used to treat 95 nonhysterectomized postmenopausal women for up to 2.5 years. This method of hormone replacements was undertaken in an attempt to avoid the withdrawal bleeding and progestogenic side effects associated with conventional cyclical therapy with estrogen and progestogen, while simultaneously protecting the endometrium from estrogenic over-stimulation. With the lower dose of estrogen, amenorrhea was achieved immediately in 30 of 46 patients (65%), and after adjustments to the dose of the progestogen in all ten patients observed for at least one year (maximum 2.5 years). With the higher dose of estrogen, irregular spotting during the first three months resulted in the cessation of treatment by six of the 49 patients (12%), but 23 (47%) women had no bleeding during that time; by 15 months, all 13 patients who had remained in treatment had become amenorrheic (maximum 2.25 years). Endometrial biopsy specimens after six months of combined treatment in 56% of patients revealed atrophic histology regardless of the dose of the estrogen.

The value of feedback in teaching interviewing skills to medical students.

Forty-eight medical students took part in a study to assess the value of giving students some feedback about their interviewing skills. During the study they all received training from their clinical firms. In addition, 36 of the students received 1 of 3 types of feedback training. This was given by tutors who used television replays, audiotape replays or ratings of practice interviews conducted by the students. As in previous studies there was little improvement in the interviewing skills of those students who only received training from their clinical firms. In contrast, all 3 feedback groups improved their ability to elicit accurate and relevant information. However, only the television and audiotape groups also showed gains in techniques. While the differences between these 2 groups were not significant, they all favoured the television group.
