Recent neuroanatomical and behavioral evidence has indicated that vasopressin (VA) increases pain threshold. The dorsal raphe nucleus (DRN) is an important nucleus in pain modulation. Anatomical studies have shown that DRN receives vasopressinergic fibers originating in the hypothalamic paraventricular nucleus. The aim of the present study was to examine the effects of intra-DRN injection of de...

We describe a case of septic arthritis caused by Pseudomonas aeruginosa in an immunocompetent patient following intra-articular ozone injection into the knee. To the best of our knowledge, and after considering the current literature,we believe this case is unique as no other reports of septic arthritis caused by P. aeruginosa following intra-articular ozone injection has been made.

We investigated 15 patients with painful hip arthroplasties using intra-articular injection of bupivicaine. Fourteen had pain relief and 13 of them were subsequently found to have loosening of one or both components. The relief of pain after total hip arthroplasty by intra-articular injection of bupivicaine indicates that a satisfactory result is probable after revision surgery with refixation ...

The central and peripheral cardiovascular effects of endothelin (ET)-1 and ET-3 were investigated in conscious rainbow trout. Both intracerebroventricular and intra-arterial injections of ET-1 (6.25-25 pmol) but not ET-3 (25 pmol) caused a dose-dependent increase in mean dorsal aortic blood pressure and a concomitant decrease in heart rate. The hypertensive effects induced by intra-arterial and...

BACKGROUND AND OBJECTIVES The consequences of missing fever in children can be grave. Body temperature is commonly recorded at the axilla but accuracy is a problem. This study aimed to evaluate the accuracy of a tympanic thermometer in the paediatric emergency setting. METHOD In a total of 106 infants, the body temperature was measured in the daytime with an infrared tympanic thermometer, and...

An outbreak of methicillin-susceptible Staphylococcus aureus joint infections occurred at an outpatient radiology center. We identified 7 case patients; all had undergone magnetic resonance arthrograms with intra-articular joint injections. The outbreak was likely due to unsafe injection practices in preparation of contrast solution for intra-articular injection.

We present an elbow disarticulation due to accidental intra-arterial injection of diazepam. Considering the risk of inadvertent and accidental intra-arterial injection of diazepam and its subsequent severe sequelae that are reported in the literature, we emphasize that intravenous diazepam should be administered with more hesitancy and care.
