Abstract: A general approach to the child with foot pain has been described. In that the pediatrician is so often the recipient of parent's questions about children's shoes, he or she should be aware of problems relating to poorly fitting shoes, probably the most common source of complaints of foot pain in children. With a systematic approach, the pediatrician is very capable of managing the majority of such complaints.

Abstract: A mathematical model was constructed to predict motor performance in rats for 8 weeks after spinal cord injury. The model is based on experimental data generated from an investigation of the static-load technique of inducing cord injury and was derived using multiple linear regression. The regression coefficients for weight of the injury-producing load were statistically significant (P less than 0.001), and it was found that the weight of the load contributes over 95% of the posttrauma motor deficit, whereas the time duration of the load resting on the cord contributes less than 5% to the deficit. Sex, pretrauma motor performance, and pretrauma body weight are insignificant covariates. The model may be used to establish expected motor deficits and to derive dose-response curves.

Abstract: Second-look laparotomy has been relied upon extensively to guide the treatment of ovarian cancer. Among patients with other than well-differentiated primary tumors, the recurrence rate approximates 50% for patients with either negative or microscopically positive findings at second-look laparotomy. Although patients with persistent microscopic disease have received additional therapy, the patients with negative findings have not. The risk of recurrence seems high enough to consider adjuvant therapy for patients with negative findings at second-look laparotomy. However, since half of the patients remain disease free for an extended interval, and in view of the potential toxicity, any adjuvant treatment should be carried out by strict investigational protocol.
