Immediate and associated complications of hysterectomy for benign disease.

Abdominal and vaginal hysterectomy are common operations for benign gynaecological conditions. Though safe operations, they are not without complications. Good medical practice requires that patients be fully counselled regarding risks involved in undergoing medical interventions. This can only be done by regular review of local practice and comparison with national and international standards. We have reviewed 502 case notes of patients who have undergone a hysterectomy for benign conditions over an 18-month period.

Prenatal diagnosis in Treacher Collins syndrome using combined linkage analysis and ultrasound imaging.

Treacher Collins syndrome is an autosomal dominant disorder of facial development, the features of which include conductive hearing loss and cleft palate. In the current investigation, linkage analysis has been used to make first trimester diagnostic predictions in a pregnancy at high risk of producing an affected child. The results of this analysis predicted that the child would be affected. As predictions of the severity of the disease were not possible, the pregnancy was also assessed by ultrasound imaging. This confirmed the affected diagnosis and predicted that the child would be severely affected.

Insulin resistance, secretion, and elimination in postmenopausal women receiving oral or transdermal hormone replacement therapy.

Estrogen/progestin steroid combinations adversely affect glucose tolerance and insulin resistance, but their effects in combined hormone replacement therapy (HRT) have rarely been evaluated. We studied 61 untreated symptomatic postmenopausal women randomized to receive oral (conjugated equine estrogens, 0.625 mg/d continuous + levonorgestrel, 0.075 mg/d for 12 days of each 28-day cycle) or transdermal therapy (estradiol 17 beta, 0.05 mg/d continuous + norethindrone acetate, 0.25 mg/d for 14 days of each 28-day cycle). An untreated control group of 30 postmenopausal women not seeking HRT was also studied. Intravenous glucose tolerance tests (IVGTT) were performed at baseline and 3, 6, and 18 months later. Mathematical modeling analysis of plasma glucose, insulin, and C-peptide concentration profiles provided measures of insulin resistance, secretion, and elimination. There were no changes in glucose or insulin concentrations with transdermal therapy. Oral therapy caused a deterioration of glucose tolerance and an increased overall plasma insulin response, apparently due to a reduction in the immediate plasma insulin response to glucose. This may have resulted from increased hepatic insulin uptake, uncompensated for by an increase in first-phase pancreatic insulin secretion. Neither treatment caused significant insulin resistance compared with baseline, but with the oral treatment insulin resistance was greater during the combined phase compared with the estrogen-only phase. Thus the oral regimen affected both insulin delivery and insulin resistance. The transdermal regimen had relatively few effects on insulin metabolism.

Comparison of transdermal and oral estrogen-progestin replacement therapy: effects on serum lipids and lipoproteins.

OBJECTIVE: We attempted to ascertain whether transdermal postmenopausal estrogen-progestin therapy has the typical effects of oral therapy on serum lipoprotein risk markers for cardiovascular disease. STUDY DESIGN: Sixty-one postmenopausal women were randomized to receive either transdermal continuous 17 beta-estradiol, 0.05 mg/day, with transdermal cyclic norethindrone acetate, 0.25 mg/day, or oral continuous conjugated equine estrogens, 0.625 mg/day, with oral cyclic dl-norgestrel, 0.15 mg/day. Twenty-nine untreated subjects served as controls. Lipoprotein profiles at 3 and 6 months were compared with baseline values by means of analysis of variance. RESULTS: In the estrogen-alone phase both therapies reduced serum levels of total and low-density lipoprotein cholesterol; high-density lipoproteins were largely unchanged. Oral therapy increased triglycerides whereas this lipid fell with transdermal therapy. In the combined phase of the cycle both therapies reduced triglycerides, total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol. CONCLUSION: Transdermal and oral therapies had similar effects on lipoprotein cholesterol but different effects on triglycerides.

A risk-benefit assessment of estrogen therapy in postmenopausal women.

Estrogen therapy is extremely effective in relieving menopausal symptoms such as hot flushes, night sweats, urogenital atrophy and certain psychological symptoms. The short term side effects from this therapy are usually mild and self-limiting. They are more common in women who commence hormone replacement therapy some years after the menopause than in those who start treatment at about the time of the ovarian failure. Pre-existing gynaecological conditions such as fibroids and endometriosis can be worsened by estrogen therapy. The majority of published studies suggest a beneficial effect of postmenopausal estrogen therapy on cardiovascular and cerebrovascular disease. These effects may be mediated by favourable changes in lipids, but other mechanisms may also be involved. It is uncertain whether the adverse changes in lipids caused by progestogen therapy will reduce any of the benefits of estrogen therapy on the cardiovascular system. Osteoporosis is the major bone disease of the Western world; long term estrogen therapy will prevent its development in most postmenopausal women. The risk of endometrial carcinoma is increased with unopposed estrogen therapy; this increased risk appears to be abolished if a progestogen is added at an adequate dose and duration for each cycle. The risk of ovarian or cervical cancer is not increased with estrogen therapy. There may be an increased risk of breast carcinoma with long term postmenopausal estrogen use, but the studies show inconsistent results.

Effects of transdermal versus oral hormone replacement therapy on bone density in spine and proximal femur in postmenopausal women.

66 early postmenopausal women were randomised to 28-day cycles of either transdermal hormone replacement therapy--continuous oestradiol 17-beta 0.05 mg daily, with norethisterone acetate 0.25 mg daily for 14 of each 28 days--or oral therapy--continuous conjugated equine oestrogens 0.625 mg daily, with dl-norgestrel 0.15 mg daily for 12 of each 28 days. An untreated reference group of 30 women were studied concurrently. Bone density was measured in the lumbar spine and proximal femur by dual photon absorptiometry at 6-month intervals for 18 months. Skeletal turnover was assessed by serum measurements of calcium, phosphate, and alkaline phosphatase, and by urine estimations of hydroxyproline/creatinine and calcium/creatinine excretion. In both treatment groups by comparison with the untreated groups by comparison with the untreated group, bone density increased in the vertebrae and proximal femur and biochemical measurements indicated a significant reduction in bone turnover.

Prolonged endometrial stimulation associated with oestradiol implants.

OBJECTIVE: To provide information on endometrial stimulation after discontinuation of treatment with oestradiol implants. DESIGN: Long term follow up of withdrawal bleeding patterns in women taking progestogens cyclically every month after oestradiol implant treatment was ended. SETTING: Specialist menopause clinic. SUBJECTS: 10 Postmenopausal patients (at least 12 months' amenorrhoea after the last spontaneous period) who were treated with oestradiol implants for typical symptoms of oestrogen deficiency. The oestradiol dose was 50 mg, reimplantation occurring roughly every six months. Patients subsequently either needed to discontinue the hormone treatment for medical reasons or expressed a desire to stop treatment. MAIN OUTCOME MEASURE: Duration of endometrial stimulation--defined as the presence of withdrawal bleeding in response to progestogen given cyclically--after insertion of the last oestradiol implant. RESULTS: Four patients eventually stopped bleeding, their mean duration of bleeding being 35 months (range 27-43 months). One patient required hysterectomy 26 months after the last implantation because of persistent irregular bleeding despite treatment with high doses of progestogen. Three patients bled for 22, 30, and 36 months and then restarted oestrogen treatment because symptoms returned. The last two patients subsequently continued to bleed 12 and 21 months after the last implantation. CONCLUSIONS: The duration of endometrial stimulation after implantation can be prolonged, up to 43 months. Insertion of oestradiol implants can carry a long term commitment to the cyclical administration of progestogen and regular withdrawal bleeding if endometrial hyperplasia and carcinoma are to be avoided.

Consequences and treatment of ovarian failure after total body irradiation for leukaemia.

OBJECTIVE: To assess the incidence and severity of physical and psychosexual symptoms in young women due to ovarian failure caused by total body irradiation for leukaemia and the women's response to hormone treatment. DESIGN: Postal questionnaire and interview. SETTING: Leukaemia unit of oncology hospital. PATIENTS: Consecutive series of 46 English speaking women who had developed ovarian failure after total body irradiation and bone marrow transplantation as treatment for leukaemia. RESULTS: Of the 36 responders, 33 reported some symptoms, vaginal dryness being the most common (29). This profoundly affected sexual function. Although 22 women had had sexual intercourse within six months after treatment, 16 were less interested in and 18 experienced difficulties with sexual intercourse. Anxieties about sterility, femininity, and appearance were common and reduced self confidence. Almost half reported that they had changed their social habits and restricted their social activities. Treatment seemed effective in abolishing symptoms in 24 women, but vaginal dryness remained a problem in three. Two women failed to respond and intercourse remained impossible. CONCLUSIONS: Such patients are vulnerable and access to gynaecologists and endocrinologists soon after treatment would be valuable. The optimal treatment regimen and the long term benefits of treatment have yet to be established.

Determinants of bone density in normal women: risk factors for future osteoporosis?

Postmenopausal osteoporosis is an important public health problem in developed countries. Preventive treatment might effect a large reduction in the incidence, but this needs to be applied selectively to those women at increased risk. Loss of bone density results in an increased risk of fractures in the classical sites of vertebrae and proximal femur. A cross sectional study of bone density measurements was carried out in these sites in British women with a modern, precise densitometric technique. Possible predictors and risk factors for bone density were assessed in these women. Bone density was measured by dual photon absorptiometry in 284 apparently healthy women volunteers aged 21 to 68. The values obtained were similar to those obtained from equivalent studies performed in women in the United States. Peak adult bone density had been attained soon after the end of linear skeletal growth. Thereafter there was some decline with age in the proximal femur, but the major fall in bone density in all sites was related to the menopause. Other factors decreasing bone density, and hence increasing risk for osteoporosis, such as low body weight, alcohol and cigarette consumption, nulliparity, lack of previous use of oral contraceptives, and lack of regular exercise, seemed to be important. None, however, could predict satisfactorily women at future risk for osteoporosis. Direct measurements of bone density in the clinically relevant sites are necessary to determine which women should received preventive treatment for postmenopausal osteoporosis. This would help make such treatment more cost effective.

Analgesia in the acute abdomen.

In a prospective sequential double blind trial 288 patients with acute abdominal pain were given sublingual buprenorphine 200 mcg, sublingual buprenorphine 400 mcg, or placebo. Pain relief was proportional to the number of tablets administered; buprenorphine had no difference in effect compared to placebo. Physical signs altered in proportion to dosage, but this had no effect on clinical diagnosis. We conclude that patients with acute abdominal pain may be given buprenorphine without fear of masking the diagnosis.
