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").

Early bone grafting in complete cleft lip and palate cases following maxillofacial orthopedics. I. The method and the skeletal development from seven to thirteen years of age.

The methods of preoperative orthopedics: a "T-traction" procedure for unilateral clefts and a combined premaxillary pressure and expansion procedure for bilateral clefts and of early alveolar bone grafting: the Nordin's "four-flap" technique, are described in detail. The subsequent effects of treatment according to those methods were studied with roentgencephalometric analysis in cleft patients from 7 to 13 years of age. They were divided into two unilateral and one bilateral complete cleft group, all having been early bone grafted.

Burns unit in Stockholm: a report on patients treated 1971--1975 for acute burn injuries.

A review of 297 burn patients treated 1971--1975 is presented to illustrate burn problems in a West European, mainly urban population. Patients were treated by exposure and warm dry air. Tubbing usually started five days after injury.

Treatment of pilonidal sinus by radical excision and reconstruction by rotation flap surgery of Z-plasty technique.

Defects after excision of large pilonidal sinuses were reconstructed by either rotation skin flaps or a Z-plasty technique. Altogether, 16 patients were operated on, 10 with a rotation flap and 6 with a Z-plasty technique. All the patients except one underwent a radical operation.

Warm dry air treatment of 345 patients with burns exceeding 20 per cent of the body surface.

Two groups of patients with burns covering more than 20% of the body surface treated in a warm dry environment in two Burn Units in Sweden have been compared. The methods of treatment of the 345 patients were almost identical, using plasma and crystalloid solutions during the period of early intense therapy, use of frequent bathing and early debridement of the necrotic burned tissue and application of homo- or heterograft skin prior to the transplantation of autograft skin. The percentage mortalities in the two groups of patients (15.

Skull injuries caused by high voltage electricity.

Four cases by high voltage electricity are reported. Particular interest is taken in describing initial conservative treatment of injuries where the entrance of the current has been through the head, followed by surgical excision and flap surgery. This procedure had an uneventful postoperative course.

Repair of incisional hernias and defects in the anterior abdominal wall using dermal grafts. Case report.

The technique and results of using autografts of dermis to repair defects in the anterior abdominal wall is shown. Dermal grafting was used in altogether 15 cases. 7 with extremely large incisional hernias, and 8 with defects after malignant abdominal wall tumours.

Different methods of reconstruction after vulvectomies for cancer of the vulva.

Direct wound closure with or without flap-plasty after vulvectomy gives satisfactory cosmetic and functional results. Split thickness skin-grafts seem to be of limited value in the repair of the defects.

Effect of phentolamine and propranolol on the survival of experimental skin flaps.

The effect of phentolamine and/or propranolol (alpha- and beta-receptor blocking compounds respectively) on the survival of skin flaps was studied in rats. Phentolamine and/or propranolol were injected intraperitoneally every 12 hours, starting one day before the flap operation, and continued for 5 consecutive days. One week after the operation the survival of the flaps was judged.

Transfixation in cross-leg procedures using Hoffman's instruments. Report of forty-two cases.

The Hoffman transfixation equipment for fracture fixation gives simultaneously an excellent fixation of a flap in cross-leg procedures. Because of these favourable results in 42 cases this method for the fixation of the extremities in predicle flap procedures is recommended. It is possible to divide the flaps much earlier than is customary.
