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: Although increased efficacy has been described with a five-day schedule of high-dose cisplatin (CDDP) in hypertonic saline, severe myelosuppression and cumulative neurotoxicity have limited the usefulness of this therapy. In order to evaluate a possible dose-response relationship in non-small-cell lung cancer (NSCLC), 17 patients with metastatic disease were treated with a modified dose schedule delivering the same total dose (200 mg/m2) in a divided day 1 and 8 schedule. During a pilot study, a total of 47 cycles of therapy were administered, with a median of three cycles per patient and a median total cumulative dose of 600 mg/m2. Nine of 17 patients received at least 600 mg/m2. While nephrotoxicity was similar to previous reports of the five-day schedule, the incidence and severity of myelosuppression and peripheral neuropathy were markedly reduced. Using this modified schedule, severe myelosuppression did not occur. Clinically severe peripheral neuropathy developed in only one patient (6%). The overall response rate was 47% (eight of 17 patients). Plasma platinum pharmacokinetics during five cycles of the modified day 1 and 8 schedule were compared with pharmacokinetics of the five-day schedule. Accumulation of plasma ultrafiltrate platinum occurred in the five-day schedule, but not in the day 1 and 8 schedule. This difference in pharmacokinetics is one possible explanation for the reduced toxicity of this modified schedule. Although the degree of activity seen in this pilot study is encouraging, the efficacy of high-dose CDDP in NSCLC remains to be defined. In view of reduced myelosuppression and neurotoxicity, further trials with this modified schedule are indicated.

Abstract: Proximal straight tubules (PST) has been shown to be an important nephron segment of renal ammonia production. To clarify the nature of glutamine (substrate of ammonia production) transport in PST, both luminal resorption and peritubular uptake of glutamine were measured in isolated rabbit PST. Luminal glutamine resorption (Jgln) was measured at various perfusate glutamine concentration (0.05 to 20 mM) at 38 degrees C and 12 degrees C. Jgln measured at 12 degrees C were proportional to mean luminal glutamine concentrations. This flux was thought to be a passive glutamine flux. The flux, which was obtained by subtracting passive glutamine flux from Jgln obtained at 38 degrees C, was thought to be active luminal resorption. This flux exhibited saturation kinetics (Vmax 20.9 pmol min-1 X mm-1, km 5.2 mM). When bath pH (HCO3) was lowered from 7.4 to 6.8, Jgln showed no change or a small decrease (12%) at perfusate glutamine concentrations of 0.05 or 5 mM, respectively. When perfusate pH (HCO3) was lowered from 7.4 to 6.8 Jgln showed a small decrease (10%) at 5 mM perfusate glutamine concentration. Peritubular glutamine uptake was determined in isolated nonperfused PST incubated for 5 to 50 min in [14C]-glutamine containing solution. When incubated in pH 7.4 HCO3 buffer solution, cell to medium 14C concentration ratio was higher than unity (3.83 +/- 0.34, P less than 0.001) at 5 min, and reached a maximum (11.37 +/- 1.13) at 30 min.(ABSTRACT TRUNCATED AT 250 WORDS)
