Transition metal sulfides have been emerging as one of the most attractive and prospective catalysts for direct conversion of solar energy into chemical fuels. The intriguing compositional and electronic characteristics...

Ulnar nerve injury as a result of closed forearm fractures in children is a rare but disastrous complication, affecting significantly the function of the upper extremity. The management of these injuries is still controversial in the literature. This is a review of small case series and case reports, in which an algorithm of treatment is proposed. A brief description of a relative case, which was treated successfully in our department, is presented as well. This case motivated the authors to perform this study.

Hand compartment syndrome is a rare condition which can result from crush injuries, fractures, burns, intravenous fluid extravasation, etc. Failing to recognize and treat it early leads to significant functional deficits of the hand. Few cases of iatrogenic hand compartment syndrome have been described in the literature so far. We present a case of a hand intravenous (IV) contrast medium extravasation injury in a 72-year-old female patient, during a CT scan. As soon as the swelling of the hand was noticed, elevation of the limb was suggested and ice was applied. Few hours later though the patient developed compartment syndrome of the hand with paresthesias and severe pain with passive movement of the fingers. Left hand emergent fasciotomies were performed leading to a good functional outcome.
