Abstract: Ten cases of endometrial carcinoma in young women aged 15 to 25 years are presented. Seven of these ten patients exhibited the clinical characteristics of Stein-Leventhal syndrome; of these, three had evidence of polycystic ovaries. Nine of the tumors were well-differentiated, adenoacanthomas (six) or adenocarcinomas (three) and limited to the endometrium. In one case, a moderately differentiated adenosquamous carcinoma involved an ovary and the pelvic wall. Treatment consisted of curettage and progestogens in three patients, one of whom later bore two children. The remainder of the women were treated with abdominal hysterectomy and bilateral salpingo-oophorectomy and/or radiation therapy. All patients for whom follow-up data are available are alive and well without evidence of disease. It is concluded that in selected young patients with well-differentiated endometrial carcinoma limited to the endometrium, conservative hormonal therapy and curettage may be adequate treatment and may preserve fertility.

Abstract: Coronary angioscopy provides images of intravascular detail with greater than 0.2 mm spatial resolution and excellent contrast resolution. Using endoscopes of 1.25 to 1.8 mm outer diameter, we performed intraoperative angioscopy of the coronary arteries or saphenous vein grafts, or both, in 58 patients. Eighty-one native coronary arteries and 43 vein grafts were examined. A clear viewing field was created by infusion of crystalloid cardioplegic solution through the aortic root during cardiopulmonary bypass. Technical details crucial for obtaining high-quality images were as follows: sufficient coronary perfusion by cardioplegic solution to displace all blood; adequate intraluminal illumination; and high-quality fiberoptic and lens systems. Incomplete studies in approximately 14% of patients were related to failure to achieve these technical details and lack of scope steerability. In 30% of patients, previously unrecognized anatomic details were revealed by angioscopy. These included intimal flaps at the site of vein-to-artery anastomoses, atheromatous plaques with adherent thrombi, and hemorrhagic ulcerated plaques, not recognized on angiography. Although a coronary intimal flap developed proximal to the anastomosis during retrograde examination in two patients, no serious complications occurred as a result of the procedure. We conclude that intraoperative angioscopy is safe, provides novel information that may be clinically relevant, and has future potential for development of the techniques for coronary endarterectomy and intraoperative balloon and laser angioplasty.

Abstract: The chronic effects of dietary protein on renal structure and function were studied in rats with normal and reduced renal mass. Control rats with two kidneys were compared with unilaterally nephrectomized rats, and with one and one-third nephrectomized rats obtained by unilateral nephrectomy and infarction of one-third of the remaining kidney. Rats at each level of renal mass were maintained on chow containing either 6% or 40% protein content. Separate cohorts of rats were studied four and eight months after ablation and institution of these dietary regimens. At both time intervals and at all levels of renal mass, rats fed the high protein diet had higher average values for GFR than comparable animals fed the low protein chow. Within each of the dietary regimens the animals with loss of renal mass developed greater prevalences of sclerotic glomeruli by eight months. Furthermore, at each level of initial renal mass, rats eating the high protein diet had a greater prevalence of sclerotic glomeruli than those on the low protein diet. Similarly, rats on the high protein diet had greater rates of protein excretion than those on the low protein diet at each degree of ablation. The prevalence of sclerosed glomeruli increased between four and eight months in each group. Thus, the extent of renal injury as manifested by proteinuria and glomerular sclerosis was directly related to the degree of initial loss of renal mass, and dietary protein restriction retarded these manifestations of injury across a wide range of initial renal mass.(ABSTRACT TRUNCATED AT 250 WORDS)
