RESUMEN
Scapula alata, also known as winged scapula, can lead to severe upper limb impairment. The shoulders' function is altered because the scapula, which supports the upper limb, is no longer stable. Typical scapula alata is described for serratus anterior palsy; however, any scapulothoracic muscle impairment may lead to scapular winging, particularly trapezius palsy, which is easy to miss, thus needed to be considered as a differential diagnosis. The diagnosis is difficult and based on various clinical tests and a thorough examination as well as electroneuromyography and MRI. The treatment ranges from conservative treatments for spontaneous recovery, nerve surgery including neurolysis, nerve transfers and nerve grafts for acute cases, to tendon transfers for more chronic cases and when nerve procedures are no longer feasible. Tendon transfers in serratus anterior palsy produce excellent results with a high rate of patient satisfaction and are described with the sternal or clavicular head of the pectoralis major; we describe our preferred technique in this article. Tendon transfers in trapezius palsy are performed with the levator scapulae, rhomboid minor and major muscles. Our preferred method is the Elhassan triple transfer. Scapula alata is a frequent and often misdiagnosed condition. Appropriate management can yield excellent results. Patients should be referred right away to specialized centers for surgery if recovery is not spontaneous.

Recognition of interosseous membrane disruption associated with radial head injury and Essex-Lopresti injury is important, especially if radial head excision is contemplated. Because a widely accepted method to diagnose interosseous membrane disruption does not exist, we evaluated the accuracy of ultrasonography to diagnose this injury in a cadaver model. Nine pairs of cadaver forearms were randomized into 2 groups. The central third of the interosseous membrane of forearms of group 1 was cut, whereas it was visualized but not cut in group 2. A dynamic ultrasound examination was performed to determine interosseous membrane integrity, and static images were made. The static images were evaluated by 2 other radiologists and interpretations were recorded. One radiologist incorrectly interpreted 1 pair of forearms; the other 2 radiologists were 100% accurate. The accuracy of ultrasonography in detecting interosseous injuries was 96% with our methods.

Forty patients who underwent rectus abdominis free-tissue transfer with split-thickness skin grafts for reconstruction of the lower extremity are reported. The procedures were performed between January, 1992 and December, 1998. Transfers were utilized for coverage of acute soft-tissue and bone defects (18 patients), defects following radical debridement of chronic osteomyelitis of the leg and foot (13 patients) or diabetic foot ulcers (eight patients), and for unstable scars (one patient). At a mean follow-up of 3.6 years, there was no donor-site morbidity; there were seven local complications--five superficial flap necroses and two flap congestions. Three flaps were totally lost. All patients but one were ambulatory and fully weight-bearing at the time of review, with consolidation of the fractures and bone defects and no evidence of recurrence of infection in the osteomyelitis or diabetic foot ulcer groups. The relatively high success rate (92.5 percent), the ease of surgical dissection, the consistency and size of the deep inferior epigastric pedicle, the absence of donor-site morbidity, and relatively low complication rates make the rectus abdominis muscle one of the preferable free-tissue transfers for these authors.

Patients who sustain high-energy, compound fractures with severe contamination and soft tissue loss, face high rates of delayed union, nonunion, infection and, in some instances, amputation. The authors reviewed 18 patients with compound foot fractures and IIIB and IIIC tibial fractures. All patients were treated by early free-flap coverage and simultaneous bone reconstruction. Corticocancellous bone grafting, composite osteocutaneous free flaps, or bone transport techniques were utilized, as required. Bony union was achieved in all cases; rehabilitation and return to work occurred within 12 to 18 months, with no major complications. The authors believe that the reconstruction ladder usually followed should be altered in certain cases in which severe periosteal stripping and soft-tissue contamination necessitate distant free composite tissue transfer, particularly those cases involving the distal third of the leg and foot. Simultaneous reconstruction is superior to other methods of wound management in providing early coverage of extensive wounds, a barrier against bacterial contamination, prevention of osteomyelitis, and enhanced union of the fractures.

Inflammation resulting from any form of tissue injury causes an increase in plasma concentration of a number of liver-derived proteins (the acute phase reactant proteins), the measurement of which provides an indication of the magnitude of the inflammatory response. C reactive protein (CRP) is an example of an acute phase protein. Although concentrations increase particularly dramatically in response to inflammation and reflect the degree of ongoing tissue damage, this method has yet to be used to assess severity of injury in traumatology and forensic medicine. The rate at which the acute phase protein response occurred after injury was therefore explored in a series of 16 patients with maxillofacial skeletal injuries and in a series of 22 age- and sex-matched control patients. Increases in the plasma concentration of CRP were not detected until 6-12 h after injury and peaked at 48-72 h. Concentration of CRP was less than 10 mgm/l in all control patients. There was significant relation between peak levels and Abbreviated Injury Scale and Injury Severity scores. Results suggest that this method of assessing the severity of traumatic injury deserves further investigation and may be of use clinically, medico-legally and in relation to compensation awards.

The quantity and physical, chemical and bacteriological quality of water from wells, tap and zeers in Port Sudan and from wells, rectified and unrectified hafirs in South Kordofan Province were investigated. The relationship between water quantity and quality and prevalence of water-related diseases was also assessed. Both areas are semi-arid and tragically suffer from shortage of water. The average per capita consumption in Port Sudan was about 1001, and about 301, in South Kordofan. All water sources in both areas were invariably contaminated with coliforms. In South Kordofan the provision of water was primarily the responsibility of women and children. Depending on the crowds and the distance of the water source people spend between 3-5 hours per day carrying water. 50% of the families have to cover more than 2 km to reach the water source. It was evident that hafirs rectification increased the amount of water stored. Tap and zeer (home pots) water in Port Sudan was also contaminated with coliforms. The content of suspended and dissolved solids and turbidity of hafirs water was exceptionally high, which warrants proper protection and water treatment before distribution to the public. Scarcity of water rather than bacterial contamination was the cause of alarmingly high prevalence of diarrhoeal, skin and eye communicable diseases (water-washed diseases) among children and adults of Port Sudan and South Kordofan Province. However, it is plausible to suggest that even minor improvements on the provided quantity of water will reduce the prevalence of water-washed diseases.
