Abstract

Fifty-one women in labor had continuous monitoring of fetal scalp tissue pH, fetal heart rate by ECG, and uterine contractions. A miniature pH electrode secured by a double spiral fetal ECG electrode was used for measurement of fetal pH every 15 seconds. The results were correlated with fetal scalp blood pH values obtained simultaneously. Fetal scalp sampling is intermittent, requires repeated scalp incisions, is subject to errors due to air mixing and coagulation of the blood sample, and is uncomfortable for the parturient. Placement of the tissue pH electrode allows continuous data recording with the minimum discomfort to the patient and the least number of fetal scalp incisions. Clinical use of the tissue pH electrode might be a practical alternative to fetal scalp samples, if the data obtained accurately reflect fetal status.

Chloroquine-resistant Plasmodium falciparum from East Africa: cultivation and drug sensitivity of the Tanzanian I/CDC strain from an American tourist.

A strain of Plasmodium falciparum, designated Tanzanian I/CDC, from an American tourist returning from Tanzania, was isolated in vitro and in the Aotus monkey. Clinically, the infection showed a late recrudescent pattern of chloroquine resistance. In 2 inoculated Aotus monkeys, the infection recrudesced after a dose of chloroquine (40 mg/kg) curative for sensitive P. falciparum strains in the Aotus monkey. In 4 ,dditional monkeys two primary infections and one of the recrudescent parasitaemias were cured with a 100 mg/kg dose of chloroquine; the second recrudescent parasitaemia was cured with an additional 40 mg/kg dose of chloroquine. The 48 h in-vitro chloroquine-sensitivity test demonstrated that the Tanzanian I/CDC strain had a pattern of chloroquine resistance similar to a reference resistant strain, the Vietnam-Oak Knoll (FVO). These studies reinforce reports which suggest that chloroquine-resistant malaria is being transmitted in East Africa.

Polymicrobial bacteremia.

Of 26,961 blood cultures taken during an 18-month period at the Cincinnati General Hospital, 1,715 (6%) were positive. Ninety-four patients had blood cultures containing more than one organism. Although aerobic and anaerobic streptococci were the most frequently isolated bacteria, a variety of microorganisms, including Staphylococcus aureus and the Klebsiella-Enterobacter-Serratia group, was isolated in different combinations depending on the underlying disease. Neurological illness, malignant neoplasms, burns, and decubitus ulcers were among the most common underlying conditions found. The overall mortality was 54%, but only 58% of these deaths were specifically related to an episode of polymicrobial bacteremia. Patient survival was significantly related to appropriate antimicrobial therapy.
