Laser-assisted removal of a foreign body from the colon

Summary An 81-year-old woman underwent a colonoscopy because of a sigmoiditis poorly responding to conservative therapy. A rod-shaped foreign body found in the sigma proved impossible to remove conventionally. Irradiation with a low laser energy caused the foreign body to break apart, after which its extraction was straightforward. The further clinical course was uncomplicated. In this case a partial sigmoidectomy would have been indicated had the laser-supported extraction not been successful. The authors suggest that a similar procedure could be helpful in the management of foreign bodies in the esophagus.

Modified gate flap for lower lip reconstruction

Summary One of the latest techniques advocated for total lower lip reconstruction is thegate flap described by Fujimori in 1980 [3]. This technique has been modified and used in two patients. With this modification, it is no longer necessary for the lateral margins of resection to extend beyond the commissure for technical purposes, and the shape of the resection does not have to be rectangular. Thus, unnecessary resection of normal tissue and macrostomia are prevented. Widely used reconstruction techniques for large lower lip defects were compared and an attempt was made to explain how to choose the proper technique for a given defect.     

Effects of continuous epidural block on motor nerve conduction velocity in patients with lower spine disorders

Thirty-one patients with severe low back pain were treated by continuous epidural block for 18±3 (mean±SEM) days. Motor nerve conduction velocity (MCV) of the common peroneal nerve was measured before and after the treatment. After the treatment, the visual analogue scale score (VAS) and straight leg-raising (SLR) test were markedly reduced (P<0.01), and MCV was increased significantly (P<0.001). A significant correlation (P<0.01) between the SLR test and MCV was found before the treatment. A significant correlation (P<0.001) between VAS and MCV was demonstrated after treatment. However, in three patients who showed no reduction in VAS even after the treatment, MCV became significantly (P<0.05) slower in spite of nearly normal SLR test results. These results suggest that epidural block treatment improves not only pain but also MCV, and that two parameters, SLR test and pain intensity, are related closely to the MCV.

Cerebral potentials preceding voluntary toe, knee and hip movements and their vectors in human precentral gyrus

In this study, the brain potentials related to voluntary, self-paced plantarflexions of the left toes, flexion of the right knee and isometric extensions of the left hip were examined in 3 groups of 10 subjects each. In the first half of the foreperiod, the Bereitschaftspotential (BP) or readiness potential for all movements was symmetrically distributed over both hemispheres. For toe and knee movements, an ipsilateral preponderance of the BP developed in the later foreperiod, which was statistically significant for toe movements. For hip movements, BP topography was symmetrical during the entire foreperiod including its second half. Since finger, hand or shoulder movements of previous experiments show a strong contralateral preponderance of the BP, the results are discussed as further support of the hypothesis that the lateralisation of the BP is due to the orientation of the precentral electrical field vector generated by an active source in the MI motor cortex. Thus, part of the somatotopic representation of the human precentral gyrus can be mapped by this non-invasive means: upper limb movements are located on the convexity; toe, foot and knee movements are generated on the mesial cortex between the hemispheres; and hip movements seem to be located at the mantle edge.     

Validation of French upper limb Erasmus modified Nottingham Sensory Assessment in stroke

Background

Somatosensory impairment of the upper limb (UL) occurs in approximately 50% of adults post-stroke, associated with loss of hand motor function, activity and participation. Measurement of UL sensory impairment is a component of rehabilitation contributing to the selection of sensorimotor techniques optimizing recovery and providing a prognostic estimate of UL function. To date, no standardized official French version of a measure of somatosensory impairment has been established.
