    Notes: Abstract Manual reduction with the index finger (modified Hutchinson's maneuver) enabling simple and safe manual reduction of infantile intussusception is described. The procedure was used in four patients, two boys and two girls, ranging in age from 2 to 15 months, as greater than normal compression was necessary and/or serosal splitting occurred during conventional reduction. The technique is as follows: in addition to the proximal bowel compression with Hutchinson's maneuver, the surgeon inserts his index finger into the intussusceptum via its neck. The finger enables the surgeon to sound a wider space between the intussusceptum and intussuscipiens, which is most likely to be responsive to bowel compression. Although the intussusceptions in the four patients were categorized as ileo-ileo-colic (three cases) and ileo-ileal (one case) types, this manual reduction technique was successful in all cases, no bowel rupture occurred, and hospitalization was no longer than with the conventional procedure. We conclude that this modified Hutchinson's maneuver may contribute to successful surgical reduction of infantile intussusception.

    Notes: Summary Neurons that project to the spinal cord were located in the mesencephalic reticular formation outside the interstitial nucleus of Cajal in cerebellectomized cats under chloralose anesthesia. Of these neurons 40% responded only at C1 (reticulospinal N cells) and the remaining 60% responded at C4 also (reticulospinal D cells). Conduction velocities of N cells were significantly slower than those of D cells. N cells and D cells responded similarly to stimulation of the whole vestibular nerves and vestibular nuclei. However, they differ in semicircular canal inputs; N cells were more responsive to canal stimulation. Comparison of properties between mesencephalic reticulospinal and interstitiospinal neurons (Fukushima et al. 1980) showed that many reticulospinal and interstitiospinal neurons have similar properties, suggesting that functionally similar neurons may be found distributed over more than one anatomically defined cell group.

    Responses of cat mesencephalic reticulospinal neurons to stimulation of superior colliculus, pericruciate cortex, and neck muscle afferents (1981)

    Notes: Summary Neurons were recorded extracellularly in the mesencephalic reticular formation outside the interstitial nucleus of Cajal in cerebellectomized cats anesthetized with α chloralose. Reticulospinal neurons were identified by antidromic stimulation of the upper cervical segments. Stimulation in the deep layers of the ipsilateral superior colliculus evoked firing in 36% of reticulospinal neurons. For many neurons thresholds for activation were high in the intermediate tectal layers and declined as the electrodes entered the underlying tegmentum. However, low threshold points were found above the deep fiber layer within the superior colliculus for some cells. Stimulation of the contralateral superior colliculus excited 10% of neurons and thresholds for activation were high above the deep fiber layer for all neurons. Stimulation of the ipsilateral and contralateral pericruciate cortex excited 39 and 21% of neurons, respectively. The lowest threshold area was found in the frontal eye fields. Sixteen percent of neurons received excitation from neck muscle afferents (C2 biventer-cervicis) bilaterally. Comparison of responses between mesencephalic reticulospinal neurons and interstitiospinal neurons (Fukushima et al. 1981) showed that responses of the two groups of neurons were similar when the pericruciate cortex and neck muscle afferents were stimulated. However, a difference was observed in tectal responses, since low threshold points were rarely observed above the deep fiber layer for interstitiospinal neurons.
