    Notes: Abstract We report a case of true esophageal carcinosarcoma, in which well-differentiated squamous cell carcinom and spindle-shaped cell sarcoma were intermingled in the primary and metastatic lesions.

    Notes: Abstract In patients 70 years or older, pulmonary function tests were performed before and after abdominal surgery to correlated the results with the development of postoperative pulmonary complications which developed in 48% of these patients, compared to 15% in the control group. To predict the development of PPC, preoperative analysis of the flow-volume curve is useful and $$4\left( {\dot V_{50} - \dot V_{25} } \right)/forced$$ vital capacity is a valuable parameter for the analysis of the flow-volume curve. Postoperatively, pulmonary function was reduced and there was a delay in the restoration of pulmonary function in cases with postoperative pulmonary complications. The administration of appropriate analgesics may be useful to improve postoperative ventilatory disturbances.

    Notes: Abstract To study post-gastrectomy metabolic bone disorders, we measured the radial bone mineral content (BMC), serum levels of calcium, inorganic phosphorus, alkaline phosphatase, and 25-hydroxyvitamin D(25-OH-D) in 59 patients with partial- and 39 patients with total gastrectomy. Total gastrectomy patients manifested a higher incidence of decreased BMC levels than did partial gastrectomy patients (56 per centvs. 25 per cent). Patients subjected to the Billroth II procedure, especially females, manifested abnormally low BMC values. The decline in BMC was age-related; it was pronounced in females. At 10 years postoperatively, many of the partial gastrectomy patients manifested markedly low BMC levels; in totally gastrectomized patients this finding was made at less than 5 years postoperatively. Approximately 30 per cent of our patients showed abnormalities in serum minerals, alkaline phosphatase or 25-OH-D.

    Notes: Abstract Serum zinc and copper levels were evaluated in patients with gastric cancer who had undergone gastrectomy. These patients were divided into two age categories; namely, the aged group, comprising 39 patients over the age of 70 years, and the younger group, comprising 23 patients younger than 50 years. The data before and after surgery were compared between the two groups. Serum zinc levels in the aged group were significantly lower than those in the younger group, both before and after surgery. Serum copper levels, however, did not differ significantly between the two groups. The serum Cu/Zn ratio was also analyzed according to the histological stages of cancer (stages I to IV), and compared between the two ageclassified groups. The aged group showed a higher Cu/Zn ratio at all stages, whereas in the younger group, the ratio was significantly higher at stage IV than in the earlier stages. Preoperative serum zinc, copper, and the Cu/Zn ratio were studied in relation to the complication of anastomotic leak after surgery. The Cu/Zn ratio in the aged patients with this complication was significantly higher than that in the aged patients without it. These results suggest that the Cu/Zn ratio may be an important factor in determining nutritional parameters in the aged.

    Notes: Abstract A decrease in the production of nitric oxide (NO) due to surgical stress has been reported. We investigated whether this decrease in NO production was related to cytokine induction and/or other clinical parameters. We therefore measured the concentrations of serum nitrite/nitrate (a stable end product of NO), serum interleukin (IL)-6, and standard clinical parameters in 13 patients undergoing major upper abdominal and thracoabdominal surgery at preanesthesia (PRE), 2 h after a surgical incision (2H), at the end of surgery (END), and on the morning of postoperative days 1 (POD 1) and 3 (POD 3). The serum concentration of nitrite/nitrate was thus found to have significantly decreased at END, POD 1, and POD 3 compared with PRE. In addition, the serum nitrite/nitrate concentration correlated negatively with the plasma lactate level, and no relationship was observed between the serum nitrite/nitrate level and either the serum IL-6 level or any other clinical parameters. Our findings thus suggest that the decrease in the serum nitrite/nitrate level might therefore be related to tissue hypoperfusion both during and after major surgery.
