Following endoscopic hemostasis of bleeding ulcers, standard-dose PPIs infusion was as effective as a high-dose regimen in reducing the risk of recurrent bleeding. (ClinicalTrials.gov number, NCT00374101).

Microsurgical treatment of ring avulsion injuries is often difficult, due to widespread intimal damage of the digital vascular bundles. Thirty-one patients with such injuries in varying degrees were treated during the period 1986 to 1992: of these, 15 underwent microsurgical revascularization. In addition to the traditional procedures applied in seven patients (arteriolysis, direct vessel suture, vein grafts), a technique consisting of vessel transfer from the middle finger was also employed. In five patients, the ulnar digital artery of the middle finger was transferred to the ring finger. In four patients, at least one vein was transferred from the dorsal aspect of the middle finger. Twelve of 15 microreconstructions were successful: with an average follow-up of 48.3 months, these patients showed very good functional (mean total active range of motion: 234 degrees and mean s2PD: 9.8mm) and cosmetic recovery. These results lead to the conclusion that, except for cases characterized by proximal amputation at the flexor superficialis tendon insertion, microsurgical treatment should always be carried out.

Epidemiological, optical and electron microscopical findings suggest that dorsal knuckle pads and Dupuytren's disease are fibrosing disorders with common features. In all cases examined, knuckle pads were always associated with Dupuytren's contracture and, in a significant number of cases, with bilateral Dupuytren's contracture. In a statistically significant number of patients with knuckle pads, Ledderhose's and Peyronie's diseases were also present (P less than 0.001). Optical and electron microscopical studies showed that cell types and extracellular matrix were identical in knuckle pads and Dupuytren's nodules in different patients.

The treatment of a degloving injury is one of the most difficult problems in hand surgery. Various reconstructive procedures have been adopted in the past years, all with poor results. Between 1988 and 1995, nine patients with degloving injuries of the hand and fingers were treated by microsurgical replantation. The injury involved the thumb in three patients, the ring finger in three patients, the little finger in one patient, and multiple fingers in two patients. Successful complete revascularization was obtained in seven patients. In one case a superficial necrosis of the replanted thumb skin occurred with good preservation of the subcutaneous layer. In one patient with a degloving injury involving multiple fingers, revascularization was achieved only in the middle finger, and the first ray was secondarily resurfaced by a free flap from the foot. In our experience revascularization of the degloved skin does represent the best solution and must be managed as an emergency procedure. Coverage obtained in this way offers the best cosmetic result and allows early mobilization with good recovery of joint movement. Reestablishing sensibility is more difficult. It is not always possible to suture the nerves damaged by the trauma, and even when a careful primary nerve anastomosis is performed, the results often are unsatisfactory, probably because of the avulsive mechanism of nerve injury.
