Previous studies have shown that thyroid hormone directly stimulates bone resorption in in vitro organ culture, and in adults excess thyroid hormone is associated with decreased bone mineral density. There are limited data in children regarding the effect of hyperthyroidism on bone metabolism and even fewer instances in the literature of hyperthyroidism presenting with bone demineralization and...
IN COARCTATION of the aorta, the coexistence of a defect of the ventricular septum tends to prevent development of hypertension in the upper systemic circulation by permitting blood from the left ventricle to pass into the pulmonary circulation. This tendency is accentuated but not fundamentally altered if there is also a patent ductus arteriosus opening into the aorta proximal to the coarctati...
Context: Pathologic aerophagia is defined as air swallowing causing abdominal distension and/or repetitive flatulence/belching present for greater than 12 weeks in a year. Pathologic aerophagia, which can be exacerbated by anxious behavior, is common in Rett Syndrome patients and can cause significant distress. Case report: We report a case of an 8-year-old female, with Rett Syndrome, who devel...
We have recently studied the electric activity of the liver in both a normal canine model and in humans, and could characterize an electrohepatogram (EHG). Regular and reproducible slow waves or pacesetter potentials (PPs) were recorded. Hepatoarrhythmic electric activity was registered in liver insult of a canine model and in liver cirrhosis. The current communication studied the hepatic elect...
The tracheas of 12 patients who had undergone autopsies after percutaneous dilatational tracheot¬ omy (PDT) were analyzed macroscopically and microscopically. The puncture site of the trachea varied from just below the cricoid cartilage (two patients) to below the third ring (three patients). A fracture of one or more tracheal rings was present in 11 patients, ofwhom 2 had a fractured cri¬ coid...
Although pathologic classifications exist for several renal diseases, including IgA nephropathy, focal segmental glomerulosclerosis, and lupus nephritis, a uniform classification for diabetic nephropathy is lacking. Our aim, commissioned by the Research Committee of the Renal Pathology Society, was to develop a consensus classification combining type1 and type 2 diabetic nephropathies. Such a c...
