Functional electrical therapy: retraining grasping in spinal cord injury.

OBJECTIVE: To determine the clinical efficacy of functional electrical therapy in the rehabilitation of grasping function for quadriplegics. STUDY DESIGN: Randomized intervention-versus-control trial. SETTING: Rehabilitation hospital for spinal cord injury in Toronto, Canada. METHODS: A total of 21 people with new spinal cord injuries ranging from C3 to C7 were randomly assigned to two groups: Control (N=9) and Intervention (N=12). The intervention was functional electrical therapy, which consisted of repetitive grasping exercises using a neuroprosthesis that applied surface electrical stimulation to the arm to generate and/or assist grasping movements. It was applied by registered Occupational Therapists in a clinical setting. Main outcome measures were: Functional Independence Measure (FIM), Spinal Cord Independence Measure (SCIM), and the Rehabilitation Engineering Laboratory Hand Function Test. Consumer perceptions of functional electrical therapy were assessed via qualitative interviews. RESULTS: Differences between the Control and Intervention groups could be observed although they are not significant due to an insufficient number of participants. Consumer perceptions were positive, including improved Activities of Daily Living and self-satisfaction. CONCLUSION: Functional electrical therapy has the potential to be an effective treatment modality to restore grasping function in quadriplegia. It can be implemented by occupational therapists in a clinical setting. Further research is required to establish suitable indications for participant selection. In addition, a larger number of participants is needed to demonstrate statistical significance of the Functional Electrical Therapy.

The basis for splenic segmental dearterialization: a post-mortem study.

The anatomical features of splenic segmental vessels in 102 human spleen autopsy specimens were analyzed. Methods applied were corrosion casting and post-mortem arteriography. The superior terminal splenic branch divided extracapsularly into 2.8+/-0.9 (range 2-5) and the inferior terminal splenic branch into 2.3+/-0.75 (range 2-5) branches per sample. The extracapsular lengths of the segmental branches ranged from 4.0 to 16.7 mm and the calibers from 0.4 to 2.2 mm. Superior polar arteries occurred in 31.3% and inferior polar arteries in 20.6% of cases. Their average extracapsular lengths were 39 mm and 31 mm, respectively. In conclusion, segmental splenic arteries have an extrasplenic origin and course, with an average length and caliber that allow surgical access and ligation, in order to achieve segmental dearterialization for hemostasis purposes and splenic preservation.

Is splenic lobe/segment dearterialization feasible for inferior pole trauma during left hemicolectomy?

We discuss splenic salvage by lobe/segment dearterialization, without resection, after intraoperative trauma, and present two cases. We performed a retrospective analysis of 163 patients in whom the colon splenic flexure was mobilized. Patients with ileo-rectal anastomosis or urgent cases were excluded. Surgical operations included left hemicolectomy and anterior resection of the rectum. Splenic procedures were splenorrhaphy, dearterialization and splenectomy. Spleen lesions occurred in 4 (2.45%) cases. One capsular tear was managed with splenorrhaphy. Three mechanical lesions to capsula and tissue of the inferior pole were managed by either splenectomy (the first case) or dearterialization. Overall mortality in the series was 4.3%. Among the patients with splenic procedures, the splenectomized patient died due to pulmonary embolism. The two cases treated by inferior splenic branch and inferior polar artery ligature are presented. In operative trauma to the inferior splenic pole, bleeding can be controlled by lobe/segment dearterialization and by methods of local hemostasis in most cases.

Herpes simplex virus infection in women with previous spontaneous abortion.

We have carried out a retrospective clinical investigation of 45 women in the first and second trimester of pregnancy aiming to demonstrate the role of genital HSV infection in the genesis of spontaneous abortion (miscarriage). Latent HSV infection was diagnosed using the microneutralization test; asymptomatic HSV vaginal or cervical shedding was diagnosed with indirect immunofluorescence and cytological-Papanicolau staining. The results showed that the highest incidence of latent HSV type 2 infection (64%) occurred in women who had one or more spontaneous abortions, whereas this type of infection was found in only 5% of pregnant women of the control group. The incidence of asymptomatic cervical HSV type 2 infection was also considerably higher in patients with a history of spontaneous abortions. Our results indicate a possible aetiological connection between HSV and spontaneous abortion.
