Recent studies have demonstrated increased morbidity in elderly patients with rib fractures after blunt trauma. As a first step in creating a multidisciplinary rib fracture clinical pathway, we sought to determine the relationship between increasing age, number of rib fractures, and adverse outcomes in blunt chest trauma patients, without major abdominal or brain injury. ⋯ Patients over the age of 45 with more than four rib fractures are more severely injured and at increased risk of adverse outcomes. Efforts to decrease rib fracture morbidity should focus not only on elderly patients but those as young as 45 years. Based on these data we have initiated a multidisciplinary clinical pathway focusing on patients 45 years and older who have more than four rib fractures.

CYFRA 21-1 has been reported as a useful tumor marker for esophageal carcinoma, but little information was reported about the clinicopathologic importance of CYFRA 21-1. The aim of this study was to analyze the clinicopathologic and prognostic significance of preoperative CYFRA 21-1 in patients with esophageal squamous cell carcinoma. ⋯ A high CYFRA 21-1 level is associated with tumor progression and poor survival in patients with esophageal squamous cell carcinoma.

The therapeutic problems of giant incisional hernias of the abdominal wall are difficult to resolve. The technique of repair must make up for the loss of abdominal wall substance and reestablish the interplay of the abdominal musculature. The use of prosthetic materials complies with these two imperatives. The aim of this prospective study was to evaluate the results of surgical treatment of postoperative incisional hernias by intraperitoneal insertion of Dacron (DuPont) mesh and an aponeurotic graft. ⋯ This prospective study shows that the intraperitoneal positioning of Dacron mesh and an aponeurotic graft can efficiently treat giant abdominal wall hernias.

We have recently shown, in an animal model, that amniotic fluid can be a source of cells for fetal tissue engineering. This study was aimed at determining whether fetal tissue constructs could also be engineered from cells normally found in human amniotic fluid. ⋯ Subpopulations of fetal mesenchymal cells can be consistently isolated from human amniotic fluid and rapidly expanded in vitro. Human mesenchymal amniocytes attach firmly to both polyglycolic acid polymer and acellular human dermis. The amniotic fluid can be a valuable and practical cell source for fetal tissue engineering.

Minimally invasive parathyroid surgery with intraoperative parathyroid hormone testing has been reported to be as successful as a bilateral operation. This study aimed to determine whether the histologic findings and outcomes differ in patients with primary sporadic hyperparathyroidism treated by a focal or a bilateral parathyroid exploration with intraoperative parathyroid hormone testing. To make the two groups comparable all patients had a solitary parathyroid adenoma identified preoperatively. ⋯ Patients with primary hyperparathyroidism having a bilateral exploration had about a 15% higher rate of multiple parathyroid tumors than did patient having a focal approach. Despite this observation all patients were normocalcemic postoperatively. This suggests that either some histologically abnormal parathyroid glands do not function or there will be recurrences in patients treated by a focused approach. Longterm followup will be necessary to determine whether patients treated by focal neck exploration will develop recurrent primary hyperparathyroidism.
