A young, previously healthy woman presented with increasing muscle pain, lower limb swelling, fatigue and eosinophilia. She had consumed L-tryptophan tablets (one to two at night) over the preceding five months for management of her insomnia. Her condition slowly deteriorated and she developed generalised oedema and severe lethargy. A white blood cell count was 21.3 x 10(9)/L with 43% eosinophils (Normal range: 4.0-11.0 x 10(9)/L with 1-6% eosinophils. A biopsy specimen of the deep fascia and gastrocnemius muscle demonstrated fasciitis and myositis. The patient failed to recover after cessation of L-tryptophan use but her condition improved rapidly without significant sequelae after systemic treatment with corticosteroids.

Eosinophilia-myalgia syndrome (EMS) is a newly recognized illness characterized by intense eosinophilia, debilitating myalgia, and absence of any condition that could account for the eosinophilia or myalgia. The disorder has previously been associated with ingestion of capsules containing the amino acid L-tryptophan. In 1989, the Wisconsin Division of Health began surveillance for EMS. Each of 25 persons reported with the illness and meeting a standardized case definition were using L-tryptophan when their symptoms began, between June 1989 and January 1990. The median age of the patients was 43 years (range 26-82 years); 92% were female, and 96% were white. The majority of patients reported were using L-tryptophan for insomnia (36%), premenstrual syndrome (28%), or depression (20%). Common signs and symptoms in these cases included cough or dyspnea (60%), arthralgia (44%), edema of the extremities (44%), fever (36%), and rash (32%). Other epidemiologic investigations to date suggest that EMS may be associated with a product contaminant.

We describe the cases of four women who developed a scleroderma-like syndrome during L-tryptophan treatment for insomnia or tinnitus. The illness was characterized by swelling of the extremities, skin rash, myalgia, and elevation of the peripheral blood eosinophil count, followed by rapidly progressive cutaneous and subcutaneous induration. The histopathologic examination of affected skin showed thickening of the fascia, deep dermal fibrosis, and accumulation of mononuclear cells and abundant eosinophils. The expression of the type I procollagen gene was examined by in-situ hybridizations of affected skin with a human sequence-specific complementary DNA (cDNA). Increased hybridization signals were detected in the deep dermis and fascia, indicating enhanced expression of the collagen gene. The temporal association of L-tryptophan use and the development of a scleroderma-like illness in these four patients suggests a causal relation between L-tryptophan or its metabolites and the stimulation of fibroblast collagen gene expression that results in dermal and fascial fibrosis.

Zidovudine (azidothymidine) is a thymidine analogue antiretroviral drug active against human immunodeficiency virus (HIV). In acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) patients, orally and intravenously administered zidovudine is effective in reducing the incidence of opportunistic infections and neoplasms, increasing helper T lymphocyte numbers, and improving survival rates and quality of life. Adverse effects include serious haematological abnormalities and severe headache, abdominal discomfort, nausea, myalgia and insomnia. In addition, neutropenia and other anaemias frequently limit zidovudine therapy and may result in a need for multiple blood transfusions, dose reductions or withdrawal of the drug. However, despite these problems and the lack of information about some aspects of zidovudine use, zidovudine provides a major hope for HIV-infected patients, and it has rapidly become the standard therapy for improving the quality and duration of the lives of AIDS and ARC patients.

The 2nd part of a review on medical therapy of endometriosis discusses pseudopregnancy brought on by oral contraceptives, and pseudomenopause induced by Danazol and GnRh agonist therapy. Oral contraceptives are not FDA approved for endometriosis, but many physicians prescribe 1 tablet daily for 2 weeks, then 2 tablets daily for 6-12 months, or higher doses in case of breakthrough bleeding. Pills cause endometrial decidual changes initially then atrophy. Danazol selectively inhibits release of FSH and LH by the pituitary, resulting in anovulation and atrophy of the endometrium. It is currently the preferred and most effective medical therapy for endometriosis, and is approved for this indication. It is used in doses of 200-800 mg in 2 divided doses, or 400-800 mg/day preoperatively. Side effects are androgenic, some of which are not reversible, antiestrogenic, metabolic and nonspecific, i.e., muscle spasms. Drug interactions such as increased insulin requirements have been reported. The GnRH antagonists, nafarelin, buserelin, histrelin and leuprolide must be given subcutaneously or nasally. The anti-ovarian side effects, hot flashes, calcium loss, vaginal dryness and insomnia are more prevalent than the androgenic side effects, weight gain, edema, myalgia, and decreased libido reported with Danazol. Clinical and laparoscopic evidence of improvement is temporary with drug treatment, in contrast to surgery. Infertility is common even with mild endometriosis, and the condition may recur, even after pregnancy.

The authors review the literature discribing non-dyskinetic antipsychotic withdrawal phenomena. Withdrawal of these agents can cause nausea, emesis, anorexia, diarrhea, rhinorrhea, diaphoresis, myalgia, paresthesia, anxiety, agitation, restlessness, and insomnia. Psychotic relapse is often presaged by increased anxiety, agitation, restlessness and insomnia, but the temporal relationship of these prodromal symptoms to reduction in the dosage or discontinuation of neuroleptics distinguishes them from the effects of abrupt withdrawal.

We conducted a double-blind, placebo-controlled trial of oral azidothymidine (AZT) in 282 patients with the acquired immunodeficiency syndrome (AIDS) or AIDS-related complex. Although significant clinical benefit was documented (N Engl J Med 1987; 317:185-91), serious adverse reactions, particularly bone marrow suppression, were observed. Nausea, myalgia, insomnia, and severe headaches were reported more frequently by recipients of AZT; macrocytosis developed within weeks in most of the AZT group. Anemia with hemoglobin levels below 7.5 g per deciliter developed in 24 percent of AZT recipients and 4 percent of placebo recipients (P less than 0.001). Twenty-one percent of AZT recipients and 4 percent of placebo recipients required multiple red-cell transfusions (P less than 0.001). Neutropenia (less than 500 cells per cubic millimeter) occurred in 16 percent of AZT recipients, as compared with 2 percent of placebo recipients (P less than 0.001). Subjects who entered the study with low CD4 lymphocyte counts, low serum vitamin B12 levels, anemia, or low neutrophil counts were more likely to have hematologic toxic effects. Concurrent use of acetaminophen was also associated with a higher frequency of hematologic toxicity. Although a subset of patients tolerated AZT for an extended period with few toxic effects, the drug should be administered with caution because of its toxicity and the limited experience with it to date.

Praziquantel (2-cyclohexylcarbonyl-1,2,3,6,7,11b-hexahydro-4H-pyrazino[2,1-a]++ +isoquinolin- 4-one, EMBAY 8440, Biltricide) has been used in 4853 patients with Opisthorchis viverrini infection. 786 patients were treated as inpatients with extensive clinical evaluation and the rest were out-patients. A cure rate (evaluated with 5 faecal samples) of 100% was obtained in groups given 6 X 25 mg/kg on 2 days and 3 X 25 mg/kg on 1 day, while in groups given 2 X 25 mg/kg, 1 X 25 mg/kg and 1 X 40 mg/kg all on 1 day the cure rates were 88, 44 and 91%, respectively. With one sample evaluation the parasitological cure rate was 96% in further 96 patients excreting the geometric mean (GM) of 5394 eggs per gram (EPG) and receiving 1 X 40 mg/kg. Another 68 patients with an egg output of 26044 (GM/EPG) and treated with 1 X 50 mg/kg showed a cure rate of 97% by similar evaluation. Side effects were mild and transient and were more frequent in higher dosage groups. They included anorexia, nausea, vomiting, abdominal pain, epigastric pain, rumbling in the abdomen, diarrhoea, lassitude, myalgia, headache, dizziness, sleeplessness, sleepiness, "hot sensation", shortness of breath, and skin rash in a few cases. Headache (30.7%) was most common in the 6 X 25 mg/kg group. In 53 patients with severe jaundice the side effects were similar. There was no evidence of toxicity. Remarkable was one patient treated with 1 X 50 mg/kg who expelled 5636 O. viverrini worms, most of which were elongated and damaged. When a single dose is prescribed it should be given at bed time to reduce the side effect of sedation.

More than 1200 patients who received pindolol for the treatment of hypertension, angina pectoris, and various arrhythmias in studies conducted in the United States were included in the New Drug Application submitted to the FDA. Nearly 1000 of these patients received pindolol as monotherapy. The side effects reported were generally transient and of mild or moderate severity. The most frequently reported side effects seen after pindolol administration, compared to those seen after placebo, were in decreasing order of incidence: headache, dizziness, insomnia, muscle pain, fatigue, weakness, nervousness, joint pain, edema, nausea, and muscle cramps. Other side effects that occurred more frequently with pindolol than with placebo but at a rather low incidence induced weight gain, bizarre dreams, visual disturbances, lethargy, and diarrhea. Nasal congestion, throat discomfort, nocturia, impotence, pruritus, anxiety, hypotension, bradycardia, and heart failure occurred only rarely. Of the 323 patients who received pindolol alone for the treatment of mild to moderate hypertension, only 20 (6.2%) were withdrawn from the study because of side effects. Overall, 3.4% of the patients treated with pindolol were withdrawn because of side effects, most of which involved the central nervous system, that is, insomnia, anxiety, dizziness, and headache. However, a few patients manifested some edema and weight gain while receiving pindolol alone. Review of the side effects data did not reveal a tendency for the incidence of side effects to be dose related. One placebo-controlled, double-blind study designed to evaluate the fixed dosages of 15, 30, and 60 mg in the treatment of mild to moderate hypertension suggested that only the incidences of insomnia and nervousness increased with increasing doses. However, these side effects were generally transient and of mild or moderate severity. The evidence indicates that pindolol has an acceptable safety profile and that any side effects that appear are generally well tolerated and disappear with continued treatment.

We prospectively studied side effects about 54 patients with chronic hepatitis C treated with 3 to 10 MIU a day of interferon (IFN) alpha, which was administrated for 16 to 24 weeks. Every day, all of them wrote down every symptoms, by themselves, during its treatment. Any symptoms occurred in all patients and each incidence of symptoms such as fever, fatigue, headache, anorexia, arthalgia, myalgia, chill, itching, insomnia, nausea, numbness of hand and foot, irritability, diarrhea, eye ball pain, vomiting, were all higher than those which have been reported by some papers in Japan. So, it was considered that the symptom self-wrighting method by patient was useful to evaluate the entity of side effects. Furthermore, we studied 26 patients, who discontinued IFN treatment because of side effects and analyzed the background factors. Each incidence of symptoms of these patients were not always compatible to those incidences. But by observation of those symptoms, we could know severe side effects earlier.
