Mycoplasmal pneumonia, tularemic pneumonia, Q fever pneumonia, psittacosis, and Legionnaires' disease are the most frequently encountered treatable atypical pneumonias. Mycoplasmal pneumonia, the most common, is often accompanied by nonexudative pharyngitis, conjunctivitis, or otitis. The nonproductive cough is characteristic. Tularemic pneumonia is characterized by substernal chest pain, bloody pleural effusion, and bilateral hilar adenopathy. Although the clinical presentation is mild, roentgenographic findings are impressive. Q fever pneumonia resembles psittacosis but is less serious; it may be accompanied by subacute bacterial endocarditis, hepatitis, or both. Psittacosis is characterized by prominent headache, bloody sputum, and relative bradycardia. Tetracycline is the drug of choice for either. In Legionnaires' disease, pneumonia is accompanied by prominent extrapulmonary symptoms. The most important diagnostic clues include diarrhea and mental confusion. Relative bradycardia and laboratory abnormalities are also helpful. Erythromycin is the drug of choice unless doubt exists as to the diagnosis.

1. This report is concerned with 44 cases of acute viral encephalitides which were seen in the eight-year period 1965-72. 2. There is a significant difference in sex distribution: 63% males and 37% females. Nearly two-thirds of our patients were aged up to 30 years. There is no seasonal accumulation of incidence of the sporadic encephalitides. 3. The clinical diagnosis was based on "influenza-like" preliminary symptoms (25 patients), acute onset of neurological symptoms (30 patients) with signs of cerebral alterations like headache, drowsiness, confusion and epilepsy (22 patients), partly focal neurological signs (14 patients), inflammatory cerebro-spinal fluid alterations (36 patients) and other virus caused simultaneous diseases like myocarditis, hepatitis, pneumonia and exanthemata (19 patients). Alterations of blood sedimentation rate, number of white or red blood cells and differential blood count have no bearing on rapid diagnosis of acute viral encephalitides. Results of usual virological examinations often come to late for early diagnosis. Neuro-radiological procedures and isotope encephalography cannot help to get diagnosis in the initialphase of encephalitis. 4. 6 patients died, 5 had residual neurological deficit. 33 patients recovered completely though they partly had severe encephalitides. 5. There is no spezific treatment of acute viral encephalitides. Application of cortisone and antipyretic drugs is not indicated. 6. Most of the viral encephalitides may be classified when an extensive virological examination will be carried out.

Sulfasalazine is an important therapeutic agent in the management of chronic inflammatory bowel disease (CIBD). Unfortunately, adverse reactions to this drug have been reported in 5-55% of treated patients. These include dose-related side effects like nausea, malaise, and headache or hypersensitivity reactions such as rash, fever, hives, arthralgia, hepatitis, etc. Studies in adults with successful reintroduction of sulfasalazine after a desensitization program have been reported; however, with regard to children, no such data are available. Fourteen children and adolescents (5-16 yr old) diagnosed to have CIBD manifested hypersensitivity to sulfasalazine within 2 months of onset of treatment. All had pancolitis--secondary to Crohn's disease (CD) in four and to ulcerative colitis (UC) in 10. All of them were on steroids. Sulfasalazine was discontinued in all after symptoms of hypersensitivity developed. Three patients with severe reaction were diagnosed prior to desensitization experience. Desensitization, beginning with 5-50 mg of sulfasalazine/day, was attempted in the other 11 children. The dose was gradually increased by 5-50 mg increments every 3 days. Desensitization was successful in only five children, who were ultimately able to tolerate 1.5-3.0 g of sulfasalazine daily again. In the rest (six of 11 patients), oral 5-ASA (Asacol) was administered, and three could not tolerate it. One of these three with intolerance to Asacol required colectomy. One did not tolerate Asacol or Dipentum. Our findings suggest that sulfasalazine desensitization should be attempted in all patients developing hypersensitivity reactions before trying alternative therapy.

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.

To assess the efficacy of therapy with alfa Interferon in chronic hepatitis C (NANB), 18 patients were enrolled in an open trial. Eleven were males and 7 females with a mean age of 43 years. Interferon alfa 2b was used in titrated doses for 9 months and the treatment was started with 5 m.U./Ti. During therapy, the patients were evaluated clinically and biochemically. A liver biopsy was done within 3 months after the completion of treatment. The serum alanine aminotransferase (ALT) level 1 became completely normal in 11 patients (61%) at 3 months of therapy and a partial response was seen in 3 (16%). At the 6 months the ALT sustained normal in 10 patients (55%) and a partial response was seen in 5 (27.7%). Four out of 7 patients (57%) who completed the therapy had complete response and 2 (28.5%) a partial response. From 5 patients who completed the follow-up, 3 (60%) had a relapse of ALT levels. A low level of ALT at the beginning of treatment had a predictive value of response to the therapy (P less than 0.05). The side effects of interferon therapy were usually mild. Fever, myalgias and headaches were seen in 72% of patients in the first two weeks of therapy. No haematological alterations were seen. We conclude that a 9 month course of interferon therapy is effective in controlling disease activity in many patients with chronic NANB hepatitis. However, the high relapse rate suggest that future studies should establish the optimal dose and duration of treatment to induce a complete resolution of the disease.

Simvastatin, a 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor, has been administered to approximately 2,400 patients with primary hypercholesterolemia with a mean follow-up of 1 year in controlled clinical studies and their open extensions. Approximately 10% of this population received simvastatin for a period of greater than or equal to 2 years. The population on whom this safety analysis is based had a mean age of 50 years; 62% were men and approximately 27% had preexisting coronary artery disease. Simvastatin was titrated to the maximal daily dose of 40 mg each evening in 56% of the study population (last recorded dose). The most frequently reported drug-related clinical adverse experiences were constipation (2.5%), abdominal pain (2.2%), flatulence (2.0%) and headaches (1%). Persistent elevations of serum transaminase levels greater than 3 times the upper limit of normal were observed in only 1% of this cohort with only 0.1% of the total population requiring discontinuation of therapy. There were no clinically apparent episodes of hepatitis. Discontinuation of therapy due to myopathy was extremely rare (0.08%). Only minimal increases in the frequency of lens opacities (1%) were observed from baseline to the last lens examination during follow-up, consistent with the expected increase in lens opacity development due to normal aging. Patients who were greater than or equal to 65 years old had a clinical and laboratory safety profile comparable to the nonelderly population.(ABSTRACT TRUNCATED AT 250 WORDS)

A 16-year-old male with acute myelogenous leukemia (M1) presented with fulminant hepatitis (massive hepatic necrosis). He achieved a complete remission with the administration of AdVP (doxorubicin, vincristine and prednisolone), and thereafter received consolidation or intensification therapy 5 times in combination with AdVP plus enocitabine. A bone marrow examination carried out before the 6th round of chemotherapy revealed a slight increase of myeloblast (7%). L-AdVP (including l-asparaginase in addition to AdVP) was administered with a good result. However, 13 days after the end of the therapy he complained of acute abdominal pain, headache and fever. The following day, his consciousness level became lower and severe jaundice appeared. The serum transaminase level highly elevated with PT and aPTT severely elongated. He was diagnosed as having fulminant hepatitis. Elevation of the titer of IgM-HBc suggested that the fulminant hepatitis was attributed to HBV, which was probably transmitted by blood transfusion done in the first induction therapy and stayed latent during immunosuppressive chemotherapy. After receiving 10 sessions of plasma exchange (3.2 l/day), he recovered, free from any major complications except posttransfusion hepatitis. In his serum taken at 1 month after the recovery of posttransfusion hepatitis, HCV (Chiron) antibody was detected. There have been few reports concerning fulminant hepatitis associated with acute leukemia. In this case, plasma exchange was very effective in treating fulminant hepatitis.

Ranitidine was first marketed in 1981; since then many patients have been treated such that much experience has been accumulated on the safety of this histamine H2-receptor antagonist in the treatment of gastroduodenal disease. A wide array of ranitidine-associated side effects has been described, but infrequently. As so much information is now available, the aim of this review is to assess the weight of evidence for a causal link between ranitidine and the reported side effects. Overall, ranitidine is well tolerated. The incidence of general side effects at less than 2% is very similar to placebo. Headaches, tiredness, dizziness and mild gastrointestinal disturbance (e.g. diarrhoea, constipation and nausea) are among the most frequent complaints, but have very seldom resulted in stopping treatment. Cardiovascular side effects are extremely rare and unpredictable with the usual doses of oral ranitidine (at most 1 in 1 million patients). They mostly comprise sinusal bradycardia and atrioventricular blockade, especially after rapid intravenous administration, receding after cessation of the drug. Clinical studies, however, have not shown a significant pharmacological effect of ranitidine on the cardiovascular system via H2-receptors, even though individual sensitivities cannot be ruled out in a few isolated reports. Ranitidine is unlikely to be directly hepatotoxic: a transient change in liver function tests has been noted in only 1 in 100 to 1 in 1000 patients. Several cases of mixed hepatitis have been reported, but very few were fully documented. The incidence of ranitidine-associated acute hepatitis has been estimated to be less than 1 in 100,000 patients. Neuropsychiatric complications may be less common and clinically quite similar to those reported with cimetidine, i.e. confusion, disorientation, hallucinations, delirium. These side effects have occurred especially in critically ill and multiple-therapy patients, or patients with chronic renal or hepatic failure, so that the direct causal link with ranitidine treatment was often difficult to ascertain. Even though an H2-receptor-mediated effect is an attractive hypothesis (since similar complications were noted with other H2-receptor antagonists), other mechanisms have been suggested to play a role, e.g. cholinergic or histaminic effects. The overall incidence of neuropsychiatric complications is probably markedly less than 1%. White cell injury (i.e. agranulocytosis) appears to be the most frequent haematological complication, even though case reports are very few and poorly documented.(ABSTRACT TRUNCATED AT 400 WORDS)

A 38-year-old man was admitted to the hospital with complaints of persistent fever up to 40 degrees C, arthralgias, headache and a nonproductive cough. The white-cell count was within the normal range but was markedly shifted to the left and demonstrated toxic granulations. Sonographic examination of the abdomen revealed a slight enlargement of the spleen. A nonspecific reactive hepatitis which was clinically asymptomatic was detected by laboratory evaluation. Diagnosis of an acute Q fever was made by demonstration of antibodies against C. burnetii. Following therapy with doxycycline, the patient became afebrile within 48 hours.

The effects of ketoconazole, a synthetic imidazole derivate, were evaluated in 42 women affected by acne (17 cases) and/or hirsutism (36 cases) treated with 400 mg/day for 3-6 months. Androstenedione, total and free testosterone, 5 alpha dihydrotestosterone and dehydroepiandrosterone levels progressively dropped during treatment while 17 alpha hydroxyprogesterone, estradiol, ACTH, cortisol, LH and FSH levels increased. Dehydroepiandrosterone sulfate decreased only towards the end of treatment, while estrone, sex hormone binding globulin, and PRL remained unchanged. Daily mean +/- SD rate of hair growth, measured by a special image analysis processor, decreased within 3 months of therapy from 0.258 +/- 0.058 to 0.184 +/- 0.039 mm/day (P less than 0.02) and mean +/- SD hair diameter from 0.123 +/- 0.015 to 0.110 +/- 0.013 mm (P less than 0.05) together with decreasing hormone levels. The therapeutic effects of ketoconazole on hirsutism was evident at 6 months in only 14 subjects, while no significant change in hirsutism score was recorded in 22 women who failed to complete the therapy. Acne improved in all cases. Several side effects and complications arose during treatment, such as headache, nausea, loss of scalp hair, hepatitis, and biochemical changes. Even though ketoconazole improves hyperandrogenism, only selected patients are eligible for treatment as scrupulous monitoring is required.
