Total parenteral nutrition during pregnancy.
Parenteral hyperalimentation or total parenteral nutrition has become an established therapy for patients with a wide variety of conditions that preclude oral feeding. Because pregnancy is an infrequent event in poorly nourished women with acute or chronic illness, total parenteral nutrition has not been widely used for pregnant patients. Some obstetricians believe that total parenteral nutrition entails risks in excess of its potential benefit to pregnancy and demands skills and knowledge that are either not available or are in limited supply. Sufficient favorable clinical experience has accumulated over the past 15 years so that total parenteral nutrition can be recommended in the management of malnutrition during pregnancy. The purpose of this report is to review the authors' experience and the literature about total parenteral nutrition during pregnancy.

A novel pattern of treponemal antibody distribution in isolated South American Indian populations.
Serologic surveys for treponemal disease were carried out in 1970-1976 among three linguistically distinct and isolated population groups in the Brazilian Amazon Region and among the Mapuche Indians of southern Chile. Three patterns were found: 1) no evidence for treponemal infection in two very recently contacted groups; 2) sporadic positive individuals in groups with long periods of contact with non-Indian populations; and 3) a high prevalence of positive tests in one cultural group with limited exposure to non-Indians. The seroepidemiology and clinical manifestations of a possible treponemal infection in those villages with a high prevalence of positive tests were unlike those of the classically described human treponematoses.
Pharmacokinetics of theophylline in hepatic disease.
The disposition of theophylline was examined in eight male cirrhotic (six proven by biopsy) patients without heart failure. An oral dose of 100 mg of theophylline per square meter of surface area was administered, and samples of serum and saliva were collected from 0 to 60 hours and were assayed by high-pressure liquid chromatographic techniques. Controls were 57 young normal subjects and 25 age-matched patients. The body clearance of theophylline in cirrhotic patients was low, averaging 18.8 +/- 11.3 ml/kg/hr (+/- SD) vs 53.7 +/- 19.3 and 63.0 +/- 28.5 ml/kg/hr in the control patients and the normal subjects, respectively. The half-life of theophylline in cirrhotic patients was prolonged wiht a mean of 28.8 +/- 14.3 hours compared to 6.0 +/- 2.1 hours in normal subjects. Patients with cirrhosis proven by biopsy had significantly lower values for body clearance and longer half-lives than subjects without biopsies. The values for body clearance correlated well with the serum level of bilirubin (r = -0.81) and the serum level of bile acids (r = -0.81). The slow and variable metabolism in cirrhotic patients necessitates a reduction in the maintenance dosage of aminophylline to 0.20 to 0.45 mg/kg/hr and monitoring of the serum level during therapy.
Epidemiology of infectious disease: the example of measles.
The situation of unacculturated Brazilian Amazon tribes is described. The isolation of these populations has been sufficiently tight that they have been free of most epidemic diseases of the cosmopolitan world, although diseases associated with persistent infection have a high prevalence. The history of measles epidemics in Amerind populations is reviewed and it is concluded that most deaths can be prevented by basic nursing care but that there is a residual excess mortality characteristic of these populations. Three Brazilian virgin-soil populations and one experienced tribe in Chile, the Mapuche, were vaccinated against measles. Elevated febrile responses were observed in the three virgin-soil populations relative to the fevers seen in the Mapuche and in cosmopolitan populations. Nutritional status, immunological experience, humoral immune response and genetic characters have been examined for an explanation of this phenomenon. The most pronounced correspondence detected so far is a high degree of homozygosity in HLA loci of the virgin populations.

Active giant cell arteritis with cerebral involvement. Findings following four years of corticosteroid therapy.
A patient had continued active giant cell arteritis proved on biopsy four years after the initial diagnosis of temporal arteritis. The patient had had erythrocyte sedimentation rates within the normal range and had been receiving corticosteroids without interruption for four years. Central nervous system symptoms occurred three and four years after the initial diagnosis.
