[Epidemiological study of Brazilian purpuric fever. Epidemic in a locality of São Paulo state (Brazil), 1986].

A case control model was used in the study of an outbreak of Brazilian purpuric fever BPF which occurred in Serrana, S. Paulo State, Brazil, in 1986. Three hypotheses were raised: 1--purulent conjunctivitis is associated with BPF; 2--a cluster effect occurs in BPF; 3--respiratory symptoms may be a variation of the clinical picture of the disease. Numerical values were attributed to different findings, as follows: fever = 5; diarrhea and/or vomiting = 1; haemorrhagic findings = 3; thrombocytopenia and/or leukopenia = 3; Haemophilus aegyptius positive hemoculture and/or Haemophilus aegyptius positive cerebrospinal fluid culture and/or H. a. oropharynx culture = 7; Waterhouse Friedrichsen syndrome = 7. Those cases for which the sum total of points reached or exceeded 13 were considered as confirmed and those obtaining between 8 and 12 were considered as suspect. Children with a score below 5 were taken as control cases. Cases and controls were matched according to sex, age and socioeconomic level. The total groups studied included 14 confirmed cases, 38 suspect cases and 78 controls. It was concluded that purpuric fever is strongly associated with previous and/or present purulent conjunctivities; a cluster effect seems to occur; respiratory symptoms such as coughing and/or coryza were not associated with BPF.

[Association of abreugraphic findings of the respiratory tract and clinical manifestations].

A retrospective study of hospital charts was conducted for the purpose of analysing the association of roent-genphotographs obtained routinely at the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, Brazil, since 1967, with the records of respiratory symptoms and pneumopathic diagnosis found in the medical case histories as from the patients' first clinical out-patient consultation at that hospital. For this purpose, 997 patients with abnormal pulmonary roentgenphotography findings were matched according to sex and age with the same number of controls (normal roentgenphotography). It was observed that in one third of the medical histories there was no record of any anamnesis of the respiratory system. A greater proportion of respiratory symptoms and pneumopathic diagnoses was registered in the case group. The same finding separated the patients into two groups according to the severity of the lesions. Hemoptysis and thoracic pain were the symptoms that better differentiated sick from normal patients. A selective utilization of roentgenphotography is recommended, with the method being applied only to patients presenting hemoptysis, thoracic pain and cough/expectoration, either alone or in combination.

A double-blind controlled trial of pipotiazine, haloperidol and placebo in recently-hospitalized acute schizophrenic patients.

Ninety recently-admitted acute schizophrenic patients, aged 18 to 40 years (mean age: 29) were stratified by schizophrenic subgroups, distributed at random among three groups (pipotiazine, haloperidol and placebo), and evaluated for 27 days by the Brief Psychiatric Rating Scale (BPRS) and Clinical Global Impression (CGI). All groups received 20 mg of haloperidol and 50 mg of chlorpromazine im during the first 3 days, followed by wash-out for 2 days and then oral pipotiazine, haloperidol or placebo for the following 21 days. The dosage was adjusted to the clinical response of the patients and the mean dose was 21.4 mg for pipotiazine and 11.5 mg for haloperidol. At the end of the trial on the 27th day there was no significant difference between pipotiazine and haloperidol, but the effect of both active drugs was significantly different from that of the placebo. In the period corresponding to the 6th to 27th day, extrapyramidal side effects (EPS) occurred to the same extent in the pipotiazine and haloperidol groups, with predominance of Parkinsonian reactions, and no EPS were observed in the placebo group. Our data for a Brazilian population confirm the only other double-blind study of these drugs reported in the literature.
