In addition to oral contraceptives (OCs), the morning-after pill, the minipill, and depot preparations also belong to hormonal contraceptives. The latter two contraceptives have not become established among young women because of inadequate cycle control. For postcoital contraception in Austria, Neogynon and Stediril-D, consisting of 0.05 mg of ethinyl estradiol (EE) + 0.25 mg of levonorgestrel, are used within 48 hours of unprotected intercourse. Lower dose OCs have considerably reduced the risks of side effects. Micropills are the optimal OCs with EE under 50 mcg combined with the new generation of gestagens. The beneficial effects include menstrual regularity and the prevention of anemia, ovarian cysts, and fibrocystic mastopathy. Nausea, headache, spotting, and weight gain do occur in individual cases, even among young people. The potential risk of thromboembolism is the most important, although arterial cardiovascular risk is minimal in young age. The probability of postpill amenorrhea is less than 1%. Micropills can be used by young diabetics provided the disease is not beyond 10 years' duration and there is no angiopathy. Acne, seborrhea, and hirsutism are beneficially influenced by a combination of 0.035 mg of EE with 2 mg of cyproterone acetate. The relative risk of endometrial and ovarian cancer are only about half as high among OC users as among nonusers. The risk of breast cancer in young OC users has not been conclusively explained. Regular colposcopy and cytology is recommended for young OC users to preclude the risk of malignancies of the genital tract. Sex education and the use of OCs that are the most suitable and effective for young people can reduce the number of unwanted pregnancies and abortion. The comparison of two 5-year periods in the 1970s and 1980s at the University Obstetrical-Gynecological Clinic in Graz showed that the incidence of births among women under 18 years of age decreased from 3.6% (778) to 1.6% (353).

We conducted a multiple-center joint study on the effects of recombinant human erythropoietin (rEPO) for predialysis patients. rEPO was intravenously administered to 42 predialysis patients (13 males and 29 females) with hematocrit (Ht) levels of less than 30%. The subjects were divided into group A (28 cases) in which rEPO was administered twice a week, and group B (14 cases) with rEPO administration once a week. The initial administration dosage was 6000IU/week. The Ht levels were 22.6 +/- 3.3% for group A and 23.2 +/- 2.7% for group B before the administration of rEPO, and increased to 31.0 +/- 4.0% and 27.7 +/- 3.7% respectively twelve weeks after initiating administration. The levels of effective improvement on anemia included 'markedly effective' in 17 cases (80.9%) and 'effective' in 2 cases (9.5%) in group A, and 'markedly effective' in 5 cases (41.7%) and 'effective' in 3 cases (25.0%) in group B. No significant change was seen in serum creatinine (Cr) levels during the study period. In the evaluation of renal function by reciprocal serum creatinine (1/Cr), a consistent tendency was not recognized; thus, suggesting that the rEPO administration had no effect on the renal function. No variation of blood pressure was seen. As far as side effects were concerned, headache and heavy headedness were recognized in four cases. There were, however, no cases in which the severity of the side effects dictated the discontinuation of the rEPO administration. In conclusion, rEPO was judged to be a safe and effective treatment for the anemia of predialysis patients.

An epidemiological study was conducted of 515 pregnant Liberian women. The purposes of the study were to 1) assess the prevalence of anemia in Liberian women during the last trimester of pregnancy (when latent deficiencies are more apt to become clinically manifest), 2) ascertain which physician-obtained symptoms are related to low hemoglobin (Hb) levels and anemia, and 3) determine the sensitivity and specificity of symptoms commonly associated with anemia. The results indicated that the prevalence of anemia (defined as Hb < 11.0 g/dl) was 79.8%. Women who had headache as a symptom had significantly lower mean Hb values than women who did not have this symptom. The socioeconomic status of women with and without symptoms was not statistically different. The sensitivity of headache as an indicator of anemia and low Hb values was 83%, but the specificity of this symptom was low (27%). The utility of signs and symptoms as indicators is discussed in relation to the economic means of lesser-developed societies and their cultural practices.

An analysis of 100 cases (43 males and 57 females) with confirmed megaloblastic anaemia is presented. The age distribution showed two peaks with 18% in the third and fourth decades and 25% in the seventh decade. Anaemia of moderate to severe degree occurred in all patients and accounted for the commonest triad of symptoms at presentation viz: weakness (73%); breathlessness (40%) and headaches (33%). Macrocytosis or macroovalocytosis and neutrophil hyper-lobulation were found in all cases; MCV greater than 100fl in 84%; pancytopenia in 47%; and megaloblastic haematopoiesis found in all patients varied from moderate to gross in severity. Thus, the finding of macrocytic anaemia with a high MCV particularly in excess of 100fl, neutrophil hypersegmentation, and characteristic megaloblastic changes in the bone marrow should dictate further appropriate investigations to help in establishing the specific diagnosis if appropriate therapeutic intervention is to be ultimately instituted.

This multi-center trial was carried out to assess the therapeutic potential of recombinant tumor necrosis factor (rTNF) as the first form of systemic therapy for advanced carcinomas of gastric and pancreatic origin. To be eligible patients were required to have no overt sign of coagulopathy and hepatic function studies with enzymes less than two times beyond the normal range. Twenty nine patients with gastric cancer and 26 with pancreatic cancer were entered from various institutions in the Southwest Oncology Group with 27 and 22, respectively, meeting eligibility criteria. Drug treatment consisted of rTNF (Genentech) given at a dose of 150 micrograms intravenously for five consecutive days every 3 weeks; 50% dose reduction was made for acute intolerance such as hypotension or severe fever and chills. Although eight patients with gastric cancer and five patients with pancreatic cancer received four or more courses of treatment, no objective antitumor responses were recorded. As in other trials common toxicities of rTNF included nausea and vomiting, chills and fever, hypotension, headache, myalgias, fatigue and malaise. However, in this trial, other toxicities became prominent: four episodes of symptomatic disseminated intravascular clotting occurred among patients with pancreatic cancer. Eleven with this disease and five with gastric cancer manifested laboratory findings of abnormal amounts of fibrin split products, and/or hypofibrinogenemia, and/or thrombocytopenia after treatment began. Other laboratory abnormalities that were commonly encountered included hyperglycemia, hypertriglyceridemia, anemia, neutropenia and an elevation in liver enzymes. We conclude that rTNF does not demonstrate antitumor efficacy against adenocarcinomas of the stomach and the pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of systemic lupus erythematosus (SLE) with benign intracranial hypertension (BIH) is reported. A 41-year-old male with a history of SLE starting in 1982 was admitted to our hospital in December 1989 because of headache and vertigo. Laboratory examinations on admission showed proteinuria, mild anemia, and positive antinuclear and anti-Sm antibodies. No abnormal findings except high pressure of 350 mmH2O were observed in his cerebrospinal fluid (CSF). Fundoscopic examinations showed marked bilateral papilledema and retinal bleeding. Brain CT, MRI and angiography revealed diffuse brain edema without space occupying lesion and cerebrovascular diseases. Because there were no diseases such as endocrinological disorders, severe anemia, and no history of the administration of drugs which might cause intracranial hypertension, the diagnosis of BIH was made. Subsequently, he was treated with intravenous methylprednisolone therapy and osmotic diuretics and his clinical symptoms and pressure of CSF gradually improved. The decrease of CSF adsorption was observed with RI cisternography in our case. Psychosis, seizures and meningitis are common CNS manifestations in SLE patients. But BIH is very rare and its cause is unclear. Only 17 cases of SLE with BIH have been reported. The pathogenesis and treatment of BIH in SLE patients were discussed in this paper.

A total of 110 nonmenopausal women (mean age 42.1 years) presenting with symptomatic uterine leiomyomata and/or fibromatous uteri have been enrolled in this trial to evaluate the efficacy of the depot formulation of leuprorelin acetate in decreasing uterine volume and minimizing menorrhagia, dysmenorrhoea and pressure over the bladder. All patients were treated with an intramuscular injection of leuprorelin acetate depot 3.75 mg every 4 weeks for 16 weeks. Clinical examinations and hormonal and ultrasound determinations were performed before, during and at the end of treatment. Appropriate follow-up is still ongoing for most patients. At the end of the treatment period, of 88 women with enlarged fibromatous uteri, 33 (37.5%) showed a decrease in uterine volume of greater than or equal to 50% of the original size, while nine (10.2%) remained with unchanged uterine volume. Of 80 fibromas measurable separately, 47 (52.8%) decreased by greater than 50% of the initial volume and 16 (18%) remained unchanged or even increased. During treatment, clinically advantageous effects were observed in the associated symptomatology, mainly in the production of amenorrhoea and restoration of normal haemoglobin levels. Most of the patients were affected by irregular menstrual blood loss with consequent anaemia that in 29 patients was expressed by low levels of haemoglobin (mean 9.2 g/dl; SD 1.5; range 4.5-11.8 g/dl). By the end of the treatment, only one patient still had moderate vaginal blood loss. Haemoglobin levels rose to a mean value of 11.8 g/dl (SD 1.3; range 8.5-14.1 g/dl). Three patients (2.7%) failed to complete the 16-week treatment protocol, because of headache (one patient) and increased blood pressure (two patients). As a result of the treatment, of the 107 patients who were candidates for surgery and who were included in this study, only nine (8.4%) required surgery during leuprorelin acetate treatment. Of these, four operations were vaginal excision of the submucous myomata protruding into the cervix during treatment, and in five hysterectomy performed because of persistence of symptoms. In most patients the achievement of amenorrhoea minimized the fear of surgical emergency, facilitating an increased awareness of their clinical condition. With the exception of the three patients who dropped out, side effects were mild in all patients, consisting mainly of hot flushes, which were easily tolerated. In the following 8-12 months, the regrowth of uterine volume to original size has been usual in most of the 82 patients now in follow-up.(ABSTRACT TRUNCATED AT 400 WORDS)

Panipenem/betamipron (PAPM/BP), a new carbapenem, was studied in dermatology. PAPM/BP was used clinically in the treatment of skin and skin structure infections in a multicenter trial. Fifty three patients were enrolled in the trial. Clinical evaluations were made in 50 patients. Most patients received intravenous infusion of PAPM/BP in a dose of 500 mg twice daily. Other dosages were used in some patients. The overall clinical efficacy rate was 78%. When 15 cases of secondary infections were excluded, the rate was 85.7%. Adverse responses were nausea and/or vomiting in 3 patients, redness with itching in 1 patient, headache or head heaviness in 2 patients and diarrhea in 1 patient. The patient with redness and itching had also nausea and vomiting. This occurred 1 hour after the start of the first infusion of this drug. After the discontinuation of the treatment the symptoms went away on the next day. Abnormalities in laboratory test results were observed in 7 out of 53 patients. One patient with liver cirrhosis and hepatocellular carcinoma developed anemia (RBC 372 x 10(4)/mm3----275 x 10(4)/mm3, Hb 11.9 g/dl----8.8 g/dl, 35.1%----26.0%). Other abnormalities were all mild. Penetration of the drug into skin tissues after intravenous infusion of 500 mg of this drug in skin surgery patients was studied. Skin/serum concentration ratios ranged from 0.20 to 0.97. Skin concentrations were higher than the concentration of PAPM inhibiting 80% of clinical isolates over a period of 6 hours. In rats, skin concentrations were much lower than serum concentrations probably due to the difference in in vivo metabolism of PAPM. A few resistant strains of Staphylococcus aureus against PAPM and imipenem (IPM) were isolated. However, PAPM and IPM showed good antibacterial activities compared to other drugs tested. In conclusion, PAPM/BP is considered to be a useful drug in the treatment of skin and skin structure infections.

A 37-year-old man suddenly fell ill with high fever (up to 39.6 degrees C), headache and lumbar pain. There was marked thrombocytopenia (minimal level of 48,000/microliters), moderate anaemia and a slow rise in serum lipase concentration to maximally 1352 U/l. Marked sinus bradycardia (to as low as 34 beats/min) occurred in the further course of the disease, as well as upper abdominal pain (endoscopically diagnosed as antral gastritis), subileus and splenomegaly. Two haemodialysis treatments were needed because of acute renal failure. An IgG antibody titre of 1:512 and an IgM titre of 1:80 against hantavirus antigen confirmed that this virus was responsible for the haemorrhagic fever with renal syndrome. This infection, transmitted by wild rodents and frequently observed in Asian countries, has a rising incidence in Central Europe. It should be included in the differential diagnosis of acute renal failure of uncertain cause.

The natural history of HIV infection continues to change with improved diagnostic and therapeutic modalities available to manage opportunistic infections and malignancies. Antiretroviral therapy with zidovudine and other investigational agents has improved the median survival of AIDS patients from 11 months in 1985 to 18-25 months at present. Most importantly, early intervention with zidovudine can delay onset of clinical illness in asymptomatic patients and progression to AIDS in symptomatic patients. A 500 mg/d dose has been found as effective as previously recommended doses of 1200-1500 mg/day. Lower doses decrease the incidence and severity of adverse effects and therapeutic benefit appears to be greatest in asymptomatic patients with CD4 lymphocyte counts less than 500/ul. Indications for zidovudine, therefore, have been expanded to include asymptomatic adults with CD4 lymphocyte counts less than 500/ul. Concerning early intervention with zidovudine, studies were not designed to measure survival or define the optimal timing of intervention based on immunologic status. In addition, long-term benefits are not clearly defined, particularly since the drug seems to lose clinical effectiveness after approximately two years, probably due to emergence of resistant HIV strains. Adverse effects continue to occur even at low doses including headaches, nausea, anemia and neutropenia, myopathy and possible hepatitis. Nevertheless, the overall clinical benefit seems to be greatest, albeit temporary, in asymptomatic patients. The optimal dosage appears to be 500-600 mg/d; however, this may not be sufficient for infection in the central nervous system.
