Results of a national retrospective survey on Hyalomatrix PA in burn patients are reported.A total of 11 burn centers were contacted.A total of 57 patients were available. Hyalomatrix PA was used on young and adult patients, mainly in deep partial thickness and full thickness burns. In most cases, Hyalomatrix PA was applied immediately after the wound cleaning (wound debridement or escharectomy for adults, dermabrasion or debridement in young patients). After 7 days, reepithelization processes were more frequent in deep partial thickness burns. One-half of the patient population underwent grafting. After 29 days, complete closure was achieved in almost all patients. The Vancouver Scar Scale showed better values for adults, while no differences were observed for burn depth or patients undergoing grafting. No adverse reactions were recorded.Hyalomatrix PA is used in young and adults, in deep partial thickness and full thickness burns, as a temporary coverage before grafting or alone for wound healing.

The authors present a case of pyloric and duodenal obstruction in an 8-year-old child, resulting from accidental ingestion of sulfuric acid. A marked pyloric and duodenal cicatrizing stenosis resulting from ingestion of sulfuric acid is seen infrequently, especially in pediatric age. Sulfuric acid produces a coagulation necrosis of the gastric mucosa and submucosa, and the process may involve the entire thickness of the gastric wall, with subsequent ulceration and fibrosis. This dynamic pathophysiologic event imposes postponement of surgical intervention because of various time length between ingestion of acid and onset of gastric outlet obstruction (17 days to 5 years). Clinical features included postprandial epigastric distress, repeated non-bilious vomiting, and marked weight loss. The authors also discuss the various surgical procedures that were employed to relieve the obstruction. Notwithstanding a potential risk of malignant evolution, a gastro-jejunostomy is the treatment of choice because of the age of the patient, and good postoperative results are confirmed by barium studies.
