Examining the impact of design-comparable effect size on the analysis of single-case design in special education.

Initially excluded from many evaluations of education research, single-case designs have recently received wider acceptance within and beyond special education. The growing approval of single-case design has coincided with an increasing departure from convention, such as the visual analysis of results, and the emphasis on effect sizes comparable with those associated with group designs. The use of design-comparable effect sizes by the What Works Clearinghouse has potential implications for the experimental literature in special education, which is largely composed of single-case designs that may not meet the assumptions required for statistical analysis.

Ocular myopathy with palpebral ptosis.

In 50% of patients with ocular myopathy with palpebral ptosis there is a familial occurrence. Only a few reports demonstrate several cases in a single family, however. Five patients within 1 family who had operations are discussed in this article.

Infected pseudo-aneurysm of the femoral artery caused by a monitoring catheter.

A patient suffering from severe burns developed a mycotic aneurysm in the femoral artery as a result of insertion of a monitoring catheter. Treatment with antibiotics and repeated arterial surgery failed and a below knee amputation was finally performed. The use of monitoring intraarterial catheters in burn patients is to be avoided, because of impaired immunity, wound infection and septicaemia in this type of patient which could facilitate the development of septic aneurysm.

Accidental burns with domestic fire-lighting fluid.

The use of methyl alcohol (methanol) as an igniting fluid is very dangerous. Nineteen patients (17 males and 2 females), burned while using this fluid for lighting barbecues or filling lamps and stoves, have recently been treated at the Burn Unit at the Karolinska Hospital. A mean of 23% body surface was involved and many of the burns were deep dermal or full thickness.

Early bone grafting in complete cleft lip and palate cases following maxillofacial orthopedics. II. The soft tissue development from seven to thirteen years of age.

The subsequent effect of preoperative maxillofacial orthopedics and early bone grafting on the development of the soft tissue profile of the face was studied with roentgencephalometric analysis on cleft patients between 7 and 13 years of age. They were divided into two unilateral and one bilateral complete-cleft group, all having been bone grafted early with the "four-flap" technique. The two unilateral groups were one group of 39 children operated on between 1960 and 1965 without preoperative orthopedics and one group of 46 children operated on between 1965 and 1972 after preoperative orthopedics ("T-traction").
