Abstract: A technique for ipsilateral femoral neck and shaft fracture using the sliding compression hip screw with plate combined with trochanteric antegrade Ender nailing of the femur was applied in two cases. Ender nails can be passed without difficulty past a compression hip screw and the bicortical plating screws. The hip and femur can be fixed internally through a single approach in a single position. Sliding compression hip screw devices can provide excellent preliminary stable femoral neck fixation. Blood supply to the femoral head is not disturbed while the femoral intramedullary fixation is performed. Antegrade Ender nailing avoids the common knee complications associated with other retrograde techniques. Decreased operative time, less blood loss, less technical difficulty, and early mobilization are important factors in the multiple-injured patient. Femoral intramedullary fixation may require open reduction, circlerage to ensure stability, and maintenance of alignment in case of significant comminution to allow early crutch ambulation. This mode of fixation may be advantageous for selected cases.

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: To evaluate the influence of plasma protein concentration and colloid osmotic pressure (COP) on blood volume and blood pressure, we studied 40 patients with the nephrotic syndrome (plasma protein 41.1 +/- 5.3 g/liter, COP 10.9 +/- 2.2 mm Hg) and 43 patients with chronic renal failure (plasma protein 65.0 +/- 5.8 g/liter, COP 22.4 +/- 3.0 mm Hg) at overhydration, during gradual edema removal to normal hydration, and occasionally, to mild dehydration. The number of measure points was 113 in the nephrotic syndrome and 92 in renal failure. In both groups blood volume was normal at normal extracellular fluid volume (ECFV). Elevation of ECFV to 300% of normal in the nephrotic syndrome occurred with only a modest elevation of blood volume (NS). Elevation of ECFV to 200% of normal in the patients with renal failure was attended by a major elevation of blood volume (P less than 0.01). Reduction of ECFV to about 10% below normal was accompanied by parallel blood volume reduction in both groups. Blood pressure was comparable at normohydration, and increased to clearly hypertensive levels only in the renal failure group with increasing ECFV and blood volume (P less than 0.01). No major blood pressure difference was observed between normal and subnormal hydration, but hypotension was observed twice in the nephrotic group. Apparently, patients with severe hypoproteinemia due to the nephrotic syndrome are generally able to preserve their blood volume even when free of edema. However, their blood volume is not elevated in overhydration, in contrast to patients with renal failure who are normoproteinemic. This difference in regulation of extracellular fluid distribution is probably related to the hypoproteinemia, and its effect to reduce tissue-fluid protein.
