We did a double blind, crossover, prospective study comparing bicarbonate and acetate containing solutions in haemodialysis. Thirty stable patients with end stage renal disease on maintenance haemodialysis while awaiting a renal transplant were each studied on three dialysis with acetate and three with bicarbonate. Nine patients developed symptoms like headache, nausea, vomiting, giddiness, and malaise and developed hypotension during acetate dialysis and three patients during bicarbonate dialysis. There were symptoms during 16.66% of acetate dialysis sessions and 5.55% of bicarbonate dialysis sessions. (P less than 0.05). There was a statistically significant decrease in PaO2 and PaCO2 on acetate dialysis at 30 minutes after initiation of dialysis. There was no significant difference in weight loss on dialysis, or in blood pressure and correction of acidosis. We conclude that bicarbonate dialysis is better tolerated, but acetate intolerance is not a major problem since we use small surface area dialysers (0.8 M2).

A comparison of the triphasic Triphasil and the combined oral contraceptive Diane 50 for treatment of acne for 6 cycles showed significant improvement in both groups. Triphasil (Wyeth-Ayerst) contains 50 mcg levonorgestrel and 30 mcg ethinyl estradiol, 75 mcg levonorgestrel and 40 mcg ethinyl estradiol for 5 days and 125 mcg levonorgestrel and 30 mcg ethinyl estradiol for 10 days. Diane 50 (Schering Ag) contains 2 mg cyproterone acetate and 50 mcg ethinyl estradiol for 21 days per cycle. 10 women in each group had physical, pelvic, ophthalmologic and neurologic exams, hematologic and biochemical screens, assays of free testosterone, sex hormone binding globulin (SHBG), androstenedione, dehydroepiandrosterone SO4 (DHEAS), progesterone, and computations of acne and hirsutism scores. Subjects had used tetracyclines, isotretinoin, erythromycin, topical clindamycin and benzoyl peroxide previously, but were withdrawn from medication in the cycle before the intervention. The mean acne scores, derived from grading and counting lesions and comedones, fell from 63.3 to 6 in the Diane 50 and from 64.2 to 4.5 in the Triphasil group. Subjective results were excellent for 6, good for 2 and unsatisfactory for 2 in the Diane 50 group, and excellent for 8 and good for 2 in the Triphasil group. In both groups mean free testosterone, androgen index, androstenedione and DHEAS, and an increase in SHBG were documented. 5 Triphasil and 5 Diane 50 subjects had increased cholesterol levels during the trial, the only abnormality detected. Side effects reported were recurrence of varicose veins and hemorrhoids in 1 women who withdrew, and complaints of mastalgia, nausea, dysmenorrhea, migraine, headache, backache and vaginal discharge.

The purpose of this study was to compare the biochemical and clinical effects of transdermal estrogen replacement therapy (tERT) in younger and older postmenopausal women. We treated 15 younger (less than 60 y) and 13 older (greater than or equal to 60 y) healthy postmenopausal women (45-72 y) with four successive 8-week regimens of tERT at doses of 0 to 150 micrograms/day, combined with cyclic oral medroxyprogesterone acetate (MPA). In both age groups, there were similar (p = .0001) dose-responsive increases in plasma estrogen levels and decreases in LH and FSH levels, although LH values were lower in older women both before and after tERT (p less than .02). The addition of MPA further suppressed LH and, to a lesser extent, FSH in both younger and older women. The ratio of estrogenized to nonestrogenized vaginal cells increased with tERT (p less than .007) in both age groups, but significant symptomatic improvement of vaginal irritation was noted only at the highest tERT dose. Adverse effects unrelated to age included short-term nausea in 4/28 women, and skin irritation at the patch sites in 20/28 women. Vaginal bleeding was of shorter duration, but breast tenderness was more common in older women. Further studies of long-term tERT effects in elderly women are indicated.

Goserelin acetate implant is a newly approved depot formulation of a luteinizing hormone-releasing hormone (LHRH) agonist indicated for palliation of advanced prostate cancer. LHRH superagonists suppress gonadotropin release from the pituitary gland by causing down-regulation of receptors. The sustained-release dosage form contains goserelin acetate dispersed in a biodegradable copolymer matrix and is designed to release active drug over 28 days. Pharmacokinetic studies have demonstrated that, despite nonzero order release of goserelin from the matrix, goserelin acetate implant maintains serum concentrations of testosterone in the range normally found in castrated men (less than 2 nmol/L) throughout the recommended 28-day dosing interval. Response rates similar to those for orchiectomy and estrogen administration have been demonstrated. Combination therapy with either diethylstilbestrol or flutamide has produced favorable results, although the major advantage appears to be a reduction in the tumor flare seen during the first week of LHRH agonist therapy rather than an increase in response rate or survival. Adverse effects are similar to other LHRH agonists and include tumor flare during the first week of therapy, decreased libido, decreased erectile potency, hot flashes, and gynecomastia. In combination with flutamide, additional adverse effects include diarrhea, nausea, vomiting, and elevated hepatic aminotransferases, all of which can be attributed to flutamide administration. Local reactions are minimal; however, some patients require a local anesthetic before goserelin acetate implant injection. The recommended dose is 3.6 mg administered subcutaneously into the upper abdominal wall every 28 days. The average wholesale cost is approximately +320 per month. Formulary addition is recommended.

A 36-year-old woman had for two months experienced progressively more marked diffuse abdominal pain, at times colicky, as well as nausea, vomiting and severe constipation. In addition, paraesthesias and motor weakness developed in the thighs. This was accompanied by a normochromic, normocytic anaemia with a haemoglobin concentration of 9.6 g/l. A short time later her mother and daughter also fell ill with similar symptoms. After symptomatic treatment had failed, secondary coproporphyria due to lead poisoning was found. The poisoning had resulted from criminal contamination of food, especially of cocoa powder, with lead acetate. Raised lead concentrations in serum were found in two other members of the family. In all the patients treatment was undertaken with sodium calcium edetate (20 mg/kg body-weight) in several three-day cycles, achieving a gradual fall in serum lead concentration. When the level had fallen to below 4 mumol/l the symptoms disappeared. Below 3 mumol/l porphyria was no longer demonstrable and the anaemia regressed. It is pointed out that, as lead poisoning may be fatal, it should be considered in the differential diagnosis of acute abdominal colic of unclear cause.

Effects of acetate and bicarbonate dialysates on tolerance to dialysis have been examined in 30 patients with chronic renal failure (CRF). Symptomatic homeostatic impairment (nausea, vomiting, headache) and cardiovascular instability (tachycardia, arrhythmia, dyspnea) were less common (p less than 0.05) in bicarbonate dialysis. The cardiovascular symptoms correlated with antihypertensive effects of acetate (p = +0.48). Tolerance to ultrafiltration was better with bicarbonate dialysis. Gas chromatographic measurement of blood acetate concentrations in 7 patients on bicarbonate dialysis showed them to be 1.4 +/- 0.31 mmol/l at the beginning of dialysis treatment and 1.7 +/- 0.24 mmol/l at its end (normal, 1.7 +/- 0.14 mmol/l). Of 26 patients on acetate dialysis, 9 patients showed initial and late acetate concentrations of 1.7 +/- 0.26 and 2.5 +/- 0.23 mmol/l, respectively, while in 17 patients an initial concentration of 4.8 +/- 0.32 mmol/l rose to 9.0 +/- 1.1 mmol/l at the end of the treatment (p less than less than 0.01). Dialysis-induced complications had a higher incidence in the latter group (p less than 0.02). Acetate dialysis was poorly tolerated by 65% of the patients. The intolerance was aggravated by myocardial lesions and slow acetate turnover indicated by blood acetate concentrations above 7-8 mmol/l.

The efficacy and safety of buserelin acetate in the treatment of endometriosis was studied in 4 open non-comparative trials and 2 open randomized comparative trials with danazol. 444 women were enrolled in the buserelin group and 89 in the danazol group. Treatment was for 6-10 months using 900-1200/micrograms intranasal buserelin/day and 400-800/micrograms oral danazol/day; patients were followed up for 6-8 months. Endometriotic lesions improved or disappeared in most women; pain (dysmenorrhoea, dyspareunia and pelvic pain) subsided rapidly. Most women had no, or alleviated, symptoms throughout follow-up, although ovarian function resumed promptly. Nearly a quarter of infertile women with a desire for children became pregnant. No significant differences between treatments emerged. Buserelin treatment was characterized by menopausal-like symptoms in most women, as well as by headache and nausea. Danazol treatment, which also gave rise to these effects, was accompanied by weight gain, myalgia and acne in a considerable proportion of women, as well as other anabolic and androgenic side effects. Buserelin would thus appear to be a safe and effective alternative to the standard therapy, danazol, in the treatment of endometriosis.

The therapeutic efficacy and safety of various doses of leuprorelin acetate depot were determined in an open, multicentre study of patients with locally advanced or metastatic prostatic cancer (stages C, D1 or D2). Patients were randomly assigned to receive 3.75 mg (30 cases), 7.5 mg (eight cases), 15 mg (eight cases) and 30 mg (one patient) leuprorelin acetate depot administered subcutaneously once every 4 weeks. Of the 43 patients evaluable, two (5%) had complete remission, 23 (53%) partial remission and 13 (30%) patients stable disease. No significant differences were observed in response rates in relation to dose, disease stage or previous hormonal therapy. Disappearance or improvement in bone pain and urinary symptoms occurred in 63% and 79% of cases, respectively. Serum androgen concentrations decreased rapidly and persistently to castration levels, without significant differences for different doses. Treatment was well tolerated with a low incidence of mild side-effects - gynaecomastia (16%), nausea/vomiting (13%) and diarrhoea (2%). It is concluded that 3.75 mg leuprorelin acetate depot given subcutaneously once every 4 weeks is able to produce hormonal effects in all patients, an overall objective response comparable to that obtained using higher doses.

Oral contraceptives (OCs, long-acting progestins (LAPs), and IUDS are reviewed in terms of new information on safety and efficacy. OC formulations are described and their mechanism of action and efficacy indicated. Reports are provided for thromboembolism, hemorrhagic and thrombotic stroke, ischemic heart diseases, alterations in lipid and hypoprotein and carbohydrate metabolism, hypertension, coagulation changes, breast and cervical cancers, and such minor side effects as menstrual irregularities, nausea, headaches, weight gain, premenstrual syndrome effects, and mood and libido changes. Noncontraceptive health benefits and clinical considerations are discussed. Norplant, as the only long acting progestin available in the US is described in terms of its formulations, mechanism of action, sequelae and metabolic effects, menstrual irregularities, metabolic effects, nuisance side effects, candidates for insertion, method of insertion and removal, and continuation rates. 2 IUD types are identified as the only ones available in the US, Progestasert T and T-Cu-380A (Paragard). Mechanism of action, efficacy, candidates, major sequelae such as salpingitis, infertility, and uterine perforation, minor sequelae such as metrorrhagia and dysmenorrhea, and other considerations are indicated. OCs in the US contain an average of 35 mg of ethinyl estradiol and assorted progestins e.g.s, ethynodiol diacetate, norethindrone acetate, nortestosterone derivatives with a complex mechanism of action. The failure rate for use effectiveness is 6 pregnancies/100 woman years. Modern formulations have combined rates of no more than 50 to 100 adverse events/100,000 users. Some of the effects are indicated as follows: Thromboembolism accounts for 60% of adverse effects and appears to be declining along with hemorrhagic and thrombotic stroke, however, modern use studies are only partially available. Myocardial infarction related to OC use may be embolic, and has a low risk at 7/100,000 users. Low-dose contraceptives substantially reduce the associated risks. Those with risk factors need close monitoring. Norplant is useful for those not wanting to take a daily regimen and is commonly accompanied by menstrual irregularity and sometimes headaches. Continuation is 80% after the 1st year and 40% after 5 years. Candidates for IUDs are parous women in monogamous relationships, who are not at risk for salpingitis, which is related to IUD use, or sexually transmitted diseases. Continuation is 70% after 1 year compared with 50% of OC users.

The efficacy and side-effects of megestrol acetate and medroxyprogesterone acetate in postmenopausal patients with advanced breast cancer were compared in a prospectively randomized study. The dosage of MA was 2 X 80 mg p.o. or MPA 2 X 500 mg p.o. daily, given as a secondary hormonal treatment, mostly after previous treatment with tamoxifen. Ninety-eight patients entered the study and 92 were evaluable for effect, 48 patients on MA and 44 on MPA. Age, main tumor site and prior treatment were not different, but there was a preponderance of ER-negative tumors in the MA group. Responses appeared to be more frequent in the MPA-treated group (25% vs. 43%), predominantly in bone lesions, 12% for MA and 45% for MPA. Median progression-free survival was comparable, 15 vs. 10 months, and overall survival was not different (20 vs. 16 months). Toxicity was frequent, occurring in 83% vs. 74% of patients: increased appetite, nausea and dizziness in more than 20%, and a preponderance of pyrosis and breathlessness on MA and hot flashes, sweating and tremors on MPA. Cushingoid symptoms were present in about a quarter of the patients treated for more than 3 months. The occurrence of thrombo-embolic episodes and cardiovascular events was evenly distributed. Patients on MPA had more often increase in body weight, systolic blood pressure and serum creatinine than those treated with MA. It is concluded that MPA may be more effective for treatment of bone metastases, at the expense of more progestational side-effects. The occurrence of Cushingoid effects is frequent but similar in both arms, while the incidence of cardiovascular or thrombo-embolic events cannot be related to the use of either compound.
