    Notes: Abstract  An adolescent maintained on continuous ambulatory peritoneal dialysis (CAPD) for 8 years had relapsing peritonitis involving peritoneal catheter tunnel infections. We attempted catheter removal and replacement simultaneously, with the catheter covered cylindrically by a rectus abdominis muscle flap to prevent recurrent tunnel infections. During 3 years of follow-up, there have been no episodes of peritonitis involving tunnel infection. Our modified insertion technique can eradicate tunnel infection, thus reducing peritonitis.

    Notes: Abstract Pathological studies have revealed that the vasculitis in Kawasaki disease (KD) begins in the intima and the adventitia of blood vessels resulting in panvasculitis. In the present study we investigated the possibility that auto-antibodies to types III and II collagen are involved in the vascular injury. Seven out of 38 patients (18%) with KD had elevated serum levels of IgG anti-body to type III collagen. None had increased serum antibodies to type II collagen. Specificity of the antibody to type III collagen in patients with KD was 86%. Three out of seven KD patients (42.9%) with coronary complications had elevated serum levels of the antibody. It is conceivable that the more severe the inflammation of systemic blood vessels, the more frequently antibodies to type III collagen are detected and coronary complications develop. Accordingly, this antibody may be secondarily detected in the serum of KD when systemic blood vessels are severely damaged. Detection of antibodies to type III collagen might be a risk factor predicting coronary complications.

    Notes: Abstract  We studied neuronal pathways for spinal reflexes activated by group-I and group-II muscle afferents in the spinal segments innervating the tail in unanesthetized and spinalized (L1) cats. Experiments were performed on 25 adult cats of both sexes. The effects of stimulating nerves innervating six tail muscles on both sides were recorded from tail motoneurons in the first coccygeal spinal segment (Co1) using glass microelectrodes. Stable recordings were obtained from 150 tail motoneurons. Stimulation of group-I muscle afferents (stimulus intensity 〈1.8 T) often produced EPSPs (82/150) after stimulating nerves innervating neighboring tail muscles. Motoneurons innervating the long-tendoned muscles, M. extensor caudae lateralis and M. flexor caudae longus (ECL and FCL), received heteronymous monosynaptic connections from group-I muscle afferents innervating the ipsilateral tail muscles. The motoneurons innervating segmental muscles, M. extensor caudae medialis and M. flexor caudae brevis (ECM and FCB), received heteronymous monosynaptic connections from group-I muscle afferents innervating tail muscles on both sides. The motoneurons innervating tail muscles originated from the Ossa coxae, M. abductor caudae externus and M. abductor caudae internus (ACE and ACI), received monosynaptic connection from group-I muscle afferents innervating most of the tail muscles on both sides. Crossed disynaptic inhibitory pathways activated by primary muscle afferent inputs were observed in ECM, ACE, FCL, and FCB motoneurons. The effects of group-II afferent inputs were not dependent on the kind of motoneuron, and alternative excitatory and inhibitory pathways were not clearly observed in the tail motoneuron pool. It is suggested that variability of the neuronal pathways from group-I and -II muscle afferents to tail motoneurons corresponds to functional relationships among tail muscles, depending on the tail movements.

    Notes: Abstract  Postsynaptic potentials (PSPs) evoked in motoneurons innervating the back and abdominal muscles in the lumbar part of the body by stimulating hindlimb cutaneous afferents were investigated in unanesthetized decerebate and spinal cats. Various types of PSP: pure excitatory postsynaptic potential (EPSP), pure inhibitory postsynaptic potential (IPSP), and mixed PSP (i.e., EPSP followed by IPSP, EPSP/IPSP; and IPSP followed by EPSP, IPSP/EPSP) were observed. The weak stimulation at 2 times threshold (2T) produced predominantly the EPSP, while at 5T the incidence of IPSP or EPSP followed by IPSP was increased. In about 20–50% of the various groups of motoneurons, PSPs evoked by ipsi- and contralateral nerves were qualitatively and quantitatively similar. For the other motoneurons, PSPs evoked by ipsi- and contralateral nerves were markedly different with respect to magnitude and/or polarity. These findings suggest that, within each motoneuron pool, some neurons act to increase stiffness of the trunk or to move vertically in response to an increased activity of cutaneous afferents, while the other motoneurons act to produce lateral bending of the trunk.
