Review of spinal cord injuries in Ireland

STUDY DESIGN

Prospective data collection on all patients with spinal cord injury (SCI) admitted for a comprehensive management programme.

OBJECTIVES

To examine the epidemiology of SCI in Ireland over 1 year.

SETTING

Ireland's National Spinal Cord Injury Centre.

METHODS

Systematic data collection on all patients admitted with SCI for management.

RESULTS

A total of 46 patients (40 males) were admitted from January to December 2000; median age was 37 years (range 6-82 years). In all, 23 of the patients presented with cervical injuries, 19 patients had thoracic injuries. In all, 18 patients had complete injuries (American spinal injuries association (ASIA)). Motor vehicle collisions were the cause of 50% of SCI.

CONCLUSIONS

The incidence of SCI in Ireland is 13.1 per million population. Demographic data from this study can go towards improving care for patients with SCI and also in the prevention of SCI.

Compartment syndrome of the well leg as a result of the hemilithotomy position: a report of two cases and review of literature

Compartment syndrome in the well leg as a complication of prolonged positioning in a hemilithotomy position is a serious complication that is rarely reported in the orthopaedic literature. A similar entity has been well described in urologic, gynecologic, and general surgery literature but, to the authors' knowledge, has been reported in only seven patients in the orthopaedic literature. The authors report two cases of unilateral compartment syndrome in a well leg during femoral nailing of the contralateral leg. Risk factors, theories of pathogenesis, and preventive measures are identified and discussed.

The rDNA Internal Transcribed Spacer Region as a Taxonomic Marker for Nematodes

The ITS region from a wide taxonomic range of nematodes, including secernentean and adenophorean taxa, and free-living, entomopathogenic, and plant-parasitic species, was evaluated as a taxonomic marker. Size of the amplified product aided in the initial determination of group membership, and also suggested groups that may require taxonomic reevaluation. Congeneric species often displayed identically sized ITS regions, but genera such as Pratylenchus and Tylenchorhynchus had species with large differences in size. ITS heterogeneity in individuals and populations was identified in several nematode taxa. PCR-RFLP of ITS1 is advocated as a method of taxonomic analysis in genera such as Helicotylenchus that contain numerous species with few diagnostic morphological characteristics.

Early left ventricular dysfunction and chelation therapy in thalassemia major

Exercise radionuclide angiography was used to assess the incidence of subclinical abnormalities of left ventricular function in 23 asymptomatic patients with thalassemia major. Left ventricular ejection fraction (LVEF) at rest was normal in 18 patients and abnormal in 5. A normal LVEF response during exercise was shown in only 5 of the patients with normal resting left ventricular function. A normal response during exercise occurred more often in those patients who had received a smaller transfusional iron load and had a lower serum ferritin level (p less than 0.05). Twelve of the twenty-three patients were receiving chelation therapy with subcutaneous deferoxamine. Ejection fraction at rest was normal in 11 of these patients. During exercise a normal ventricular response was shown in 4 patients. After 1 year of intensive chelation therapy in these 12 patients, left ventricular function was reassessed. A normal exercise response was seen in an additional 4 patients; 3 of these showed an increase in peak exercise LVEF, and in the remaining patient no change of peak exercise LVEF was shown. The response during exercise was unchanged in 3 patients and had deteriorated in 1 patient.
