Objectives: The purpose of this study was to examine the effect of race on whether or not a patient would accept an invasive cardiac procedure when referred by a physician.

Methods: A retrospective longitudinal review of medical records at a public health hospital in southeastern Louisiana was conducted to determine cardiovascular patient acceptance/ rejection differences. Patient charts were examined using specific indicators (type of pain, laboratory values, blood pressure, and radiographic tests) to determine which patients were eligible to be referred.

Objectives: The purpose of this study was to examine physician bias when patients present with cardiovascular disease in a teaching hospital that treats a majority of African American patients. Physician bias was deemed to occur when cardiovascular disease patients did not receive an invasive procedure when needed.

Methods: The hospital in the study was a teaching facility in southeastern Louisiana.

The purpose of this study was to investigate racial and gender differences in the utilization of invasive procedures for cardiovascular treatment. Medical records data of 3015 patients were abstracted from a Medical System Database from 1999 to 2001. Logit models were used to estimate the adjusted odds in the utilization, referral, and acceptance of invasive procedures, while controllingfor confounders (age, race, sex, comorbidity, disease severity, payer type, marital status and family history) simultaneously.

One hundred sixty-one women undergoing laparoscopy for infertility of obstructive origin (fallopian tube stenosis or obstruction and periadnexal adhesions) had thorough bacteriologic studies, including Chlamydia trachomatis cultures, of their lower and upper genital tracts. Peritoneal or tubal fluid cytologic features and biopsies of fallopian tubes or adhesions were also studied after each laparoscopy. The serum of each woman was titrated for evidence of C.

Cultures of specimens from the abdominal cavity (14) or the lower genital tract (11) were positive for Chlamydia trachomatis in 25 (22.7%) of 110 patients with a laparoscopic diagnosis of acute salpingitis. Microimmunofluorescence serodiagnosis showed positive IgG levels (greater than or equal to 1/64) in 35 patients (32%).

Chlamydiales are bacteries showing a growth cycle unique among procaryotes. The two species Chlamydia trachomatis and Chlamydia psittaci are genetically very distant and their pathogenicity for man is very distinct. Human chlamydia infections by Chlamydia trachomatis are diseases chiefly sexually transmitted and their epidemiological importance is growing.

I.--After showing that bank voles are parasited only by Ixodes ricinus larvae, the authors attempt to found different factors (demographic, biometric, and sexual) who favor individual parasitism. The authors conclude to absent of anti tick immunity for this rodent specie.

Rabies virus haemagglutinin has not hitherto been obtained to our knowledge, from brain material of infected animals. A slight modification of the arbovirus technique and the use of trypsin treatment can reveal a good haemagglutinin from fixed and street strain from infected brains.

This work shows the montly variation in the density and stage composition of the population of the tick Ixodes Ricinus in the Rhine forest. Some factors influencing this variation are analysed. These include the locality of egg-laying and of down localisation and the main climatic variables.

A yellow fever outbreak occurred in 1966 in Arba-Minch District, east of Abaya Lake, in Ethiopia. The present study was undertaken to assess the southern limits of that epidemic and to contribute to the inventory of arboviruses and potential vectors in that area. In the highlands 90 sera were collected, in the lowlands 140.

The authors present here the results of a serological survey on arbovirus infections, which was conducted on 116 out of 505 inhibitants of Wuvulu island, the westernmost island of the Bismarck archipelago, located 260 km north of Wewak, Papua-New Guinea. The islanders are divided in two communities of unequal size: the Wuvulian themselves, who are Micronesians, and the coconut workers who are Melanesians coming from the Sepik district. In addition to the presence of a group A virus, this survey shows a recent infection in the Melanesians by Dengue type 2 virus, probably during the 1971-72 epidemic.

An epidemiologic and serologic study of arboviruses was done in 1972 in the basin of Lake Rudolf. The main object of this study was to demarcate the southern limit of the yellow fever epidemic which occurred from 1959 to 1962 in Southern Sudan and Ethiopia. Other purposes were to contribute to the inventory of arboviruses and their distribution in this region.
