    Abstract A 17-year-old boy had a 2-day prodrome of fever and mild sore throat followed by 2 episodes of severe anginal chest discomfort and substantial transient ST-segment elevations in the anterior leads of the electrocardiogram. A subsequent evaluation showed the 2 episodes were most likely coronary vasospasm complicating acute viral myocarditis.

    Abstract We used polysomnography, echocardiography and ventilatory measurements to study 50 patients suspected of having OSA to determine a link to RVH. Twenty-eight patients (56 percent) had OSA and 20 (71 percent) of those had isolated RVH. We evaluated patients with RVH and divided them into two groups, those with apnea and those without apnea. The patients with sleep apnea were younger, weighed more, had greater BSA and had lower average oxygen saturations during the sleep study period. We divided the group with apnea into those with RVH and those without it. Those patients with RVH had a higher AI, longer average apnea time, a greater duration of longest apnea and a lower average oxygen saturation for the period of the sleep study. In addition, those with RVH had a lower average oxygen saturation during each apneic episode with a p value equaling 0.09.

    Abstract The effect of an alanine load per se on hepatic alanine balance and hepatic glucose production is unclear. To examine this question, alanine was infused into six postabsorptive dogs at a rate of 6 mumol/kg-min, while maintaining insulin and glucagon levels using the pancreatic clamp technique. The arterial alanine concentration rose from a basal level of 227 +/- 16 mumol/L to 497 +/- 40 mumol/L during alanine infusion (P less than .01). The net hepatic fractional extraction of alanine remained unchanged, while hepatic alanine uptake increased from 3.0 +/- 0.3 to 6.0 +/- 0.4 mumol/kg-min (P less than .01). Conversion of alanine into glucose increased 87% to 2.7 +/- 0.3 mumol/kg-min during alanine infusion (P less than .01) while gluconeogenic efficiency remained essentially unchanged. Despite the increased gluconeogenic rate, the total rate of glucose production was unchanged. These data suggest that an increase in the alanine load to the liver causes a proportional increase in net hepatic alanine uptake and the gluconeogenic rate, but that in an overnight fasted animal this increase is insufficient to significantly increase glucose production.

    Abstract The effects of sodium dichloroacetate (DCA) on carbohydrate metabolism in conscious, 48-h-fasted dogs were examined using the hepatic A-V difference technique and a double isotope infusion technique (3H-glucose to measure glucose production and 14C-alanine to assess gluconeogenesis). DCA infusion (0.4 mg/kg-min) resulted in an 82 +/- 1% fall in the arterial plasma alanine level and a 53 +/- 8% fall in the arterial whole blood lactate level. Hepatic uptake of alanine and lactate fell 67 +/- 5% and 59 +/- 15%, respectively, although the fractional extraction of these intermediates was not altered. DCA decreased the conversion of circulating alanine and lactate to glucose but by only 41 +/- 7%, suggesting that a slight increase in the efficiency of the intrahepatic gluconeogenic process took place. This may be explained by the decrease in the plasma insulin level (39 +/- 9%) that occurred in the presence of an unchanged plasma glucagon concentration. Despite the substantial fall in the levels of gluconeogenic precursors in blood and the considerable decrease in their rate of conversion to glucose, the overall rates of glucose production and the blood glucose concentration were not altered by DCA. These data indicate that the alanine and lactate supplied by the periphery after a 48 h fast in the dog are not essential for the acute maintenance of glucose production or euglycemia. They suggest, further, that a compensatory increase in glucose production can occur by drawing on an alternate intrahepatic carbon source, the nature of which and signal for which remain unclear.
