Perioperative hemodynamic changes in ischemic heart disease patients undergoing dental treatment.

Twenty patients with stable ischemic heart disease in functional capacity Class II-IV underwent dental treatment. Scaling was performed in seven patients without local anesthesia. In the remaining 13 patients, pain control for restoration placement was obtained by local anesthesia: in seven patients, the anesthetics contained epinephrine, while in six this drug was omitted. Heart rate, blood pressure, and electrocardiograph were continuously monitored during the dental session. All patients had elevated systolic blood pressure and rate pressure product during treatment. In the patients who received plain local anesthetics only, the elevation in systolic blood and rate pressures was, however, significantly lower than the ischemic threshold. Arrhythmia or ST segment depression of > or = 1 millimeter were not recorded in any of the subjects. In severely compromised ischemic heart disease patients undergoing routine dental procedures of limited chair time, plain local anesthesia seems to be the preferred analgesic modality.

Femoral hypoplasia--unusual facies syndrome: prenatal ultrasonographic observations.

FH-UFS is a rare syndrome characterized by bilateral femoral hypoplasia, together with facial dysmorphism. To the best of our knowledge, this is the first report describing prenatal ultrasonographic findings and in utero growth pattern of an infant with FH-UFS. Via analysis of our data it appears that the growth of the femur in our case was normal until the 24th week of pregnancy, at which time some in-utero insult occurred, resulting in temporarily arrested femoral growth. From the 34th week of pregnancy onward femoral growth rates returned to normal. We assume, therefore, that the etiology of FH-UFS is multifactorial. Only a combination of some hereditary proclivity, together with an intrauterine insult (possibly viral) could explain the appearance in the same fetus of cleft palate, developing at the 7th week of gestation, and a time-specific (25-32 weeks) disturbance of femoral growth.

Microbial contamination of enteral feeding solutions in a community hospital.

Seven related studies were done to estimate the type and amount of contamination that occurred in nutrient feeding solution when administered according to procedure in a community hospital. The initial study was done in a simulated nonclinical setting with select technicians monitoring for gavage systems delivering a commercially prepared nutrient feeding solution. The solution remained sterile over 48 hr. In the second study, various nurses maintained the enteral feeding simulations unaware of the objective of study. Significant contamination was found, but a decrease occurred when the study was duplicated and the nurses were made aware that contamination was the issue being studied. The subsequent study had all gavage equipment in clinical use in the hospital on a given day cultured for microbial contamination. Significant contamination was present and did not decrease when the study was duplicated following inservice training. Suggestions for standards of care are made.

A florid case of borderline-lepromatous leprosy.

A case of borderline-lepromatous leprosy is presented to highlight the detection and prevalence of florid, new cases of leprosy towards the lepromatous end of the spectrum in the northern and western regions of Australia; the recognition and early treatment of lepra reactions; and the potential use of an enzyme-linked immunosorbent assay to detect and to monitor immunoglobulin M levels in leprosy.

Platelet function in humans is not altered by hyperbaric oxygen therapy.

A pilot survey of platelet function was performed on 6 patients undergoing hyperbaric oxygen therapy (2.0 ATA O2 for 2 hours, 6 days/week) for prophylaxis against osteoradionecrosis. Blood was drawn immediately prior to and after the first, tenth and twentieth treatment for measurements of platelet aggregation, ATP release and expression of activated alphalIb3 integrin. No significant differences were observed due to hyperbaric oxygen exposures.
