    Full Text Available É apresentado um caso de meningopatia leucêmica com um quadro de hipertensão intracraniana, que surgiu 18 meses após a remissão clínica e hematológica de leucemia aguda. A terapêutica por via intratecal com o Amethopterin, na dose de 5 mg, repetida 6 vêzes e com intervalos de 5 a 7 dias, proporcionou melhora clínica imediata e normalização do LCR após dois meses de tratamento. O paciente continuou bem clinicamente e com o sangue e o LCR normais após 4 meses de observação. A experiência dêste caso e daqueles citados na literatura justificam que todos os pacientes leucêmicos sejam cuidadosamente observados a fim de se poder diagnosticar precocemente uma complicação neurológica, para que o tratamento adequado possa permitir maior sobrevida. O exame do LCR tem importância decisiva no diagnóstico desta complicação; ulteriormente, os exames seriados do LCR orientam a duração e a intensidade do tratamento. A padronização do tratamento das complicações neurológicas das leucemias constitui campo aberto às investigações.

    Objective:To communicate the presence of adult females,rabditoid larvae and eggs of Strongyloides stercoralis(S.stercoralis)in the respiratory secretions obtained by tracheal aspirate from a HIV-negative patient who was suffering from polymyositis,and treated with corticoids and amethopterin and assisted by pneumonia.Methods:The respiratory secretions submitted to the Parasitology Laboratory of the Mu(?)iz Hospital were made more concentrated by centrifugation(1 500 r/min for 15 seconds).Wet mount microscopy was performed with the pellet.Results:It revealed adult females,rabditoid larvae and eggs of S.stercoralis.Further parasitological studies performed after the start of the treatment with ivermectin on fresh fecal samples,gastric lavages and tracheal aspirates showed scanty mobile filariform and rabditoid larvae of the same parasite.Conclusions:The presence of adult female S.stercoralis which has never been observed before in the clinical samples submitted to our Laboratory for investigation can be considered as an indirect marker of the severe immunosupression of the patient.

    Results are presented on the effect of immunosuppressive substances such as chlorambucil, cyclophosphamide, azathioprine, amethopterine and a cortizone derivate of betamethasone, on the development of Fasciola hepatica in the rat. The suppression of the immune response of the host to immunosuppressants was reflected in an earlier start of migration of the flukes to the common bile duct, and in an earlier onset of egg production as compared with that in the controls. Of the substances employed, cyclophosphamide and betamethasone were the most effective ones within the period from week 2--6 p.i., which is the time during which the migration of the flukes in the liver parenchyma is highest. Pathological changes in the liver of the animals were less marked than those of the infected controls. Evidence was obtained on an increased pathogenicity of infective larval flukes causing a higher mortality of the hosts in comparison with that of the control animals. On the other hand, the administration of immunosuppressants did neither influence the total number of developed flukes nor the appearance of eosinophilia in the peripheral blood of the treated animals.

    Objective:To explore the cause of drug-induced hematuria. Methods:To analyse for clinical information of 52 cases of drug-induced hematuria in the data and reason. Results:The drugs causing hematuria were sulfa drugs, diclofenac, indocin, centamyein, cefradine, cefletin, ciprofloxacin, oflxaein and amethopterin.These patients had historical to use related drugs. Clinical maniteslations: hematufia, cryslats by microscopic examination of uria, skin rash in a small mumber of patients. Old people were more (51.92%) in these patients. All patients were fully recovered by stoping drugs and symptomatic treatment. All patients recovered not recured by following and visiting them at six months. Conclusion:In order to avoid occurrence of the disease, clinical doctors should master strictly medication indications and prevent to abuse drugs and try to use fewer or no drugs of nephrotoxicity particularly in elderly patients and educate patients to use drugs under the guidance of doctor as much as possible and no blind.%目的:探讨药物所致血尿的病因.方法:对52例药物性血尿的临床资料进行数理分析.结果:表明引起血尿的药物有磺胺类、双氯酚酸、消炎痛、庆大霉素、头孢拉啶、头孢氨苄、环丙沙星、氧氟沙星、甲氨蝶呤.患者有使用相关药物史,临床表现为血尿,镜检尿液有结晶体,少数患者有皮疹,老年患者较多(51.9%).停用药物及对症处理后痊愈.随访6个月无复发.结论:为避免该症的发生,临床医生应严格掌握用药指征,防止滥用药物,尽量少用或不用肾毒性药物,特别是老年患者,并教育患者应尽可能在医生指导下用药、不要盲目用药.
