Abstract: The renal effects of carbohydrates (CHO) were studied in two experiments. 1) The effects of CHO-energy restriction was evaluated by comparing uremic growing rats (initial weight: 80 g) fed "ad lib" (L rats) or CHO-restricted (starch and glucose) but receiving identical amounts of all other nutrients (R rats). R rats showed reduced growth, slower increase in plasma creatinine, lower mortality rate, and less histological renal damage than L rats. 2) Two types of CHO restriction, low glucose (R1 rats) or low starch (R2 rats) were compared to "ad lib" feeding (L1 rats) in adult rats (initial weight: 130 g). Growth was identically reduced in R1 and R2 rats. Mean plasma creatinine levels at week four was lower in R1 than in L1 rats. The overall rate mortality was higher for L1 and R2 than in R1 rats (79%, 81%, 53%) but included deaths from other causes than renal failure. Actuarial survival excluding these deaths was 27%, 83% and 10% in L1, R1 and R2 rats, respectively. Diffuse renal lesions were found in 25 of 30 L1, 5 of 15 R1, and 12 of 15 R2 rats (R1 vs. R1 and R2, P less than 0.01). The results show that CHO restriction may preserve the renal parenchyma, and suggest that restriction of "simple" rather than "complex" CHO restriction may be beneficial, a finding which could be of clinical importance if confirmed by further investigations.

Abstract: The course of a pregnant patient at term who was acutely exposed to carbon monoxide is described. A review of the fetal-maternal carboxyhemoglobin relationships and the differences in fetal oxyhemoglobin physiology are used to explain the recommendation that pregnant women with carbon monoxide poisoning should receive 100% oxygen therapy for up to five times longer than is otherwise necessary. The role of hyperbaric oxygen therapy is considered.

Abstract: The records of 165 patients with diaphragmatic injuries seen at Detroit Receiving Hospital from July 1980 through June 1985 were reviewed. Causes included gunshot wounds in 89 patients, stab wounds in 65, and blunt trauma in 11. Mortality rates were 18%, 5%, and 27%, respectively, deaths being caused primarily by bleeding from associated injuries. Operations on these patients included laparotomy in 123 (75%), thoracotomy in four (2%), and both in 38 (23%). The mortality rates for these operations were 0%, 50%, and 53%, respectively. A presumptive preoperative diagnosis of diaphragmatic injury from chest x-ray findings was possible in only 24 (15%) patients. Of 42 thoracotomies, five were performed in the emergency department for cardiac arrest, with three (60%) deaths. Of 37 thoracotomies performed in the operating room, 17 were for thoracic injuries with six (35%) deaths and 20 were for resuscitation for abdominal injuries with 13 (65%) deaths. In most patients, the diaphragmatic injury was critical only in warning the surgeon that severe injuries might be present in both the chest and abdomen. Of 43 patients admitted with a blood pressure of less than 70 mm Hg or four or more associated injuries, 22 died. However, even in these high-risk patients, if resuscitation raised the initial operating room blood pressure to more than 70 mm Hg, reduced the shock time to less than 30 minutes, and kept blood loss below 10 units, the mortality was only 8% (1/12). In contrast, if none of these conditions could be met, the mortality in this high-risk group was 100% (16/16). Thus more aggressive resuscitative efforts and earlier control of bleeding seem to provide the best chance for improved survival.
