Question: Abstract: Operative management of a patient with septic thrombosis from Candida organisms of the subclavian and central veins is described. Diagnosis was suspected on the basis of positive blood and catheter tip cultures, indium-labeled leukocyte scan, and bilateral upper extremity phlebograms. Venous thrombectomy with a Fogarty catheter of the upper extremity central veins was performed after a superior vena cava Greenfield filter had been placed to prevent pulmonary embolism. The thrombus culture was positive for Candida albicans, and the reestablishment of vein patency in conjunction with amphotericin B therapy resulted in cure. This technique allows a definitive diagnosis of septic central thrombosis to be made and reestablishment of vein patency may also enhance antibiotic therapy.

Question: Abstract: The split hydronephrotic kidney preparation was used to directly observe the effects of locally applied dopamine on the in vivo diameters of renal vessels. Dopamine (1 X 10(-6) to 3 X 10(-5) M) produced a concentration-dependent dilation of the arcuate and interlobular arteries and afferent arterioles. Efferent arterioles near the glomeruli also dilated to dopamine but the dilation was less than that of the preglomerular vessels. Higher dopamine concentrations (3 X 10(-4) and 1 X 10(-3) M) produced more variable effects, with a tendency for the arcuate and interlobular arteries and the afferent and efferent arterioles away from the glomeruli to decrease in diameter. After pretreatment with haloperidol, dopamine (1 X 10(-6) to 1 X 10(-4) M) did not dilate any pre- or postglomerular vascular segment, but the tendency for pre- and postglomerular constrictions with higher dopamine concentrations were not abolished. Pretreatment with phentolamine and propranolol enhanced the dilator response of the pre- and postglomerular vessels (except the afferent arterioles near glomeruli and efferent arterioles near welling points) to dopamine (3 X 10(-5) and 1 X 10(-4) M), and abolished the reductions in diameter produced by the high dopamine levels. These data indicate that the dilator effect of dopamine is mediated by interactions with specific dopaminergic receptors, while alpha and beta adrenergic receptors appear to mediate a constrictor influence observed with high dopamine concentrations. The overall effect of dopamine on the renal vessel diameters thus appears to depend on the balance of dilator and constrictor stimuli mediated by multiple receptors.

Question: Abstract: Symptomatic assessment and oesophageal investigations were done in 25 consecutive patients with the irritable bowel syndrome attending a gastroenterological clinic. Symptoms of gastro-oesophageal reflux, dysphagia, and a globus sensation were significantly commoner than in a control group of fracture clinic patients. Ambulatory oesophageal pH monitoring showed clearly abnormal reflux in 11 of 22 patients (50%). Nine patients had macroscopic endoscopic changes and a further 11 biopsy changes alone, of oesophagitis which was thus present in 80% overall. Lower oesophageal sphincter pressure was significantly less in irritable bowel patients than in age and sex matched controls, but upper oesophageal sphincter pressure was comparable in the two groups and disordered peristalsis was not found. Oesophageal symptoms in the irritable bowel syndrome are mainly caused by gastro-oesophageal reflux predisposed to by a subnormal lower oesophageal sphincter pressure, rather than by oesophageal spasm.
