A retrospective study of speech development in patients with submucous cleft palate treated by four operations.
Fifty patients with submucous cleft palate (SMCP) who had had four different operations were reviewed. The operations were pushback palatoplasty (n = 18), pharyngeal flap (n = 21), pushback palatoplasty combined with a pharyngeal flap (n = 8), and Furlow palatoplasty (n = 3). Postoperatively the speech of 8, 19, 7, and 2 patients, respectively, improved so that it was within normal limits. ⋯ They all improved, five achieving relatively normal speech, and one good speech. No patient developed hyponasality or airway compromise associated with the pharyngeal flap. The results show that pharyngeal flap and pushback palatoplasty combined with a pharyngeal flap seem to be more reliable procedures than pushback palatoplasty for patients with SMCP.

Tissue engineering of high density porous polyethylene implant for three-dimensional reconstruction: an experimental study.
Three-dimensional defects have been reconstructed with carved and remodelled frameworks wrapped within vascular carriers. If sufficient vascular penetration can be established without any change in the size and shape of an implant, it will be possible to cover it with a skin graft and aesthetically important fine details can be obtained. To achieve this, we first prefabricated high-density porous polyethylene implant in rabbits. ⋯ A total of 10 implants were prefabricated and then grafted in five rabbits. The implants were evaluated by perfusion scintigraphy and histological examination. Results showed that the implants were invaded by fibroneo-vascular tissue, and that this tissue, which can be transferred as a pedicled or a free flap, was sufficient to sustain a skin graft.

Comparative StudySkeletal muscle blood flow after prolonged tourniquet ischaemia and reperfusion with and without intervening reoxygenation: an experimental study in rats using laser Doppler perfusion imaging.
The total, safe, time available for operating during tourniquet ischaemia is thought to be prolonged by short, intervening episodes of reperfusion. However, animal experiments have suggested that this may cause a reduction of the postischaemic reperfusion injury. The purpose of the present study was to investigate the effect on final postischaemic reperfusion of intermittent, short periods of reperfusion compared with that of prolonged, continuous tourniquet ischaemia. ⋯ The postischaemic reperfusion after three hours of ischaemia with a short reperfusion interval was not reduced after ischaemia compared with either that in controls or to that in the group exposed to only 1.5 hours of tourniquet ischaemia. These findings support the clinical practice of using intervening periods of reperfusion to prolong the total tourniquet time that can safely be used. There were no adverse effects on postischaemic reperfusion from intermittent reoxygenation.

We organised a prospective series to study, the epidemiology and causes of burns in the city of Bergen, Norway. We included 361 patients treated during one year at the casualty centre or at the burn centre at the hospital. Thirty-six per cent (n = 131) of the patients were less than 15 years old, and 9% (n = 33) were over 60. ⋯ Scalds were more common among women than among men, while firework and flame burns were more common among men. Burns occurred at home in 227 patients (63%), at work in 58 (16%), and during leisure activities in 76 (21%). The mean surface area burned was 3.5% total body surface area (TBSA); patients who were admitted had a TBSA of 18% compared with 1.8% among those treated as outpatients.

Randomized Controlled Trial Clinical TrialBilateral infraorbital nerve block is superior to peri-incisional infiltration for analgesia after repair of cleft lip.
Cleft lip repair is a common operation in infants and requires that the child is pain-free during the postoperative period so that handling does not affect the integrity of the delicate surgical site. This study was designed to compare the efficacy and duration of effect of 0.125% bupivacaine given preoperatively as a bilateral infraorbital nerve block with peri-incisional infiltration of the same local anaesthetic for postoperative analgesia in cleft lip repair. It was a randomised, double blind, prospective study in 30 children aged 4-20 months (ASA grade 1). ⋯ The analgesic requirement in group B became significant at two hours postoperatively, while group A had significant analgesic requirements only after eight hours. The significant rise in heart rate and blood pressure that accompanied tracheal intubation in both groups suggested that while both methods of analgesia may be adequate to prevent responses to skin incision, they do not substitute for adequate systemic analgesia during the operation. We conclude that infraorbital nerve block with 0.125% bupivacaine provides better and more prolonged analgesia than peri-incisional infiltration in cleft lip repair.
