    Notes: Abstract The Wilms' tumor gene (WT1) encodes a transcriptional regulator involved in growth and differentiation of various tissue types. A continuous over-expression of WT1 was found in leukemic blasts, thus suggesting an oncogenic function. Solid cancer entities have also been described as expressing WT1. We systematically analyzed WT1 expression in small-cell and non-small-cell lung cancer, colon cancer and glioblastoma patients and in the respective tumor cell lines. Using reverse transcription/polymerase chain reaction, we found WT1 expression in glioblastoma (5 of 8), lung (5 of 11), and colon cancer (5 of 15) cell lines. While WT1 was expressed in only 1 of 12 lung cancer and 1 of 5 glioblastoma specimens, it was not detected in colon cancer or macroscopically tumor-free colon and lung tissue. In addition, HT29 colon cancer cells showed a loss of WT1 expression when grown to confluence or induced to differentiate by sodium butyrate. From this evidence, testing for WT1 expression is not clinically relevant for colon cancer, lung cancer, or glioblastoma patients. WT1 expression in cancer cell lines can probably be attributed to optimized in vitro growth conditions.

    Notes: Summary Six women and one man presenting with chronic urinary retention for 〉1 year were restored to normal voiding after implantation of a neuroprosthetic device. Detrusor contractions could not be elicited in a preoperative urodynamic investigation, and failure of urethral sphincter relaxation was noted in all cases. Test stimulation of the pudendal and sacral nerve roots resulted in normal motor responses. A temporary wire electrode was inserted in either the S3 or the S2 foramen and the patient was connected to a self-controlled pulse generator for 3–5 days. Voiding returned within the first 24 h and continued for the duration of the test. Retention recurred after removal of the temporary wire electrode. Permanent electrodes were then inserted. Five patients continue to void normally at 2–48 months (mean, 16 months) postimplantation. These subjects demonstrate that chronic retention can be the result of impaired reflex triggering of the voiding reflex in the presence of completely normal motor pathways. Sacral nerve root stimulation can identify this subset of patients and restore their normal voiding function.

    Notes: Summary The neuroprosthetic approach for management of the spinal injury bladder is proving to be a valuable form of therapy. Stimulation of the ventral roots of S3–4, unilaterally or bilaterally, can effectively return control of bladder evacuation to a patient. The dorsal rhizotomy of the S2–4 nerves, performed at the same time as the electrode implant, has significant therapeutic benefit by itself. Bladder spasticity is reduced, which can correct reflux, restore continence, and decrease the risk of renal loss associated with urinary tract infection. Patients must be appropriately selected for the technique from a medical, psychological, urological and neurological point of view. Quality of life is greatly enhanced in these patients without significant risk. The following discussion addresses the evolution of and experience with the extradural method for implanting electrodes to control the spinal injury bladder.

    Notes: Summary Neuromodulation of sacral roots provides an alternative mode of treatment for patients presenting with voiding dysfunctions and chronic pelvic pain. To date, the implantation of permanent electrodes into the sacral foramen and long-term chronic stimulation have not resulted in peripheral nerve damage. In this paper, we describe the surgical technique used for sacral foramen electrode implantation. The nuances of this therapy are illustrated by case reports.

    Notes: Summary Neuromodulation of sacral roots provides an alternative mode of therapy for patients presenting with voiding dysfunctions and chronic pelvic pain. Physiologically, this is accomplished by intervention in the neuronal pathways of micturition via sacral nerve-root electrical stimulation. Preoperative evaluation using temporary percutaneous sacral root stimulation selects the patients who are most likely to benefit from permanent electrode implantation. To date, no evidence of peripheral nerve damage has been recorded. Our experience with 〉1500 percutaneous tests and 150 permanent foramen implant procedures documents the safety and efficacy of this technique.

    Notes: Summary Transformations of the underlying movement control of rapid sequential (reversal) responses were examined as the movement amplitude (Experiment 1) and moment of inertia (Experiment 2) were altered, with constant movement time. Increases in amplitude and inertia were both met by sharply increased joint torques with a constant temporal structure, suggesting that the alterations may have been governed by a single gain parameter. The durations of various EMG bursts were essentially constant across changes in inertia, supporting a model in which the output of a fixed temporal representation is amplified to alter joint torques. The EMG amplitudes increased greatly with both amplitude and load. However, the fact that the EMG durations increased systematically with increases in distance provided difficulties for this model of amplitude control. The data suggest an economy in motor control in simple agravitational movements, whereby relatively simple transformations of an underlying representation can accomodate large changes in movement amplitude and moment of inertia.
