Neurological complications of herpes zoster.

We report 31 cases of herpes zoster (HZ) with neurological complications: 14 with cranial nerve deficits, 1 with cranial nerve deficit associated with segmental motor disorder, 3 with segmental motor deficits, 2 with meningoencephalitis, 2 with meningoencephalitis associated with cranial neuropathy or myelitis, 2 with meningitis, 2 with hemiplegia contralateral to the ophthalmic HZ. 1 with hemiplegia and motor deficit and finally 1 with hemiplegia and a cranial neuropathy. Smoking was the putative risk factor in 53% of our patients together with diabetes, which has already been mentioned in the literature. We frequently observed more than one complication in succession (19.3%) that could not easily be related to the cutaneous distribution. Acyclovir had no demonstrable positive effects on neurological complication in our patients.

Response to RIT 4237 oral rotavirus vaccine in breast-fed and formula-fed infants.

Twenty-six full-term newborns (15 males and 11 females) were followed-up from birth to 5 months of age. During the first month of life, all of them were breast-fed. Thereafter those infants whose mothers produced enough milk continued breast-feeding (n = 16) while the remaining (n = 10) changed to an adapted milk formula supplying approximately 2 g/kg/day of protein and 100 Kcal/kg/day. At 4 months of life, all infants were vaccinated with one oral dose of RIT 4237 rotavirus vaccine of bovine origin. Before and one month after the vaccination, total protein immunoglobulin and IgM type antibodies against rotavirus were evaluated in serum. Growth, weight, length, head circumference and nutritional serum parameters were comparable in both groups of infants as well as the immune response to the RIT 4237 vaccine. Moreover, the "take" of RIT 4237 oral rotavirus vaccine was not lowered by the concomitant administration of human breast-milk which is known to contain rotavirus antibodies. Therefore, breast-feeding is probably not a contraindication for vaccination with RIT 4237, which is most important in developing countries where rotavirus infection is common in young infants and results in acute diarrhoea often leading to death.

Tangier disease. A case with sensorimotor distal polyneuropathy and lipid accumulation in striated muscle and vasa nervorum.

A 65-year-old man with Tangier disease (analphalipoproteinemia) had had a progressive sensorimotor distal neuropathy with sensory ataxia for 1 year. Muscle biopsy demonstrated excess lipid vacuoles on histochemical and electron-microscopic techniques. Sural nerve biopsy showed a marked loss of large fibers and an increase in small myelinated fibers, with presence of remyelinating fibers and clusters of regeneration; a few aspects of active demyelination and some onion-like formations were also present. Lipid accumulation chiefly affected the Schwann cells of unmyelinated fibers and, to a lesser degree, of myelinated fibers, endoneurial fibroblast, and vasa nervorum. Teased fibers showed prevalent aspects of de-/remyelination and, often in association, marked myelin wrinkling suggesting axonal atrophy. This Tangier patient differs from known cases for the presence of a distal symmetrical sensorimotor polyneuropathy (not previously reported in Tangier disease) and because of the morphological findings of de-/remyelination coexisting with aspects of axonal atrophy and previous degeneration, and of lipid accumulation within striated muscle and vasa nervorum. This latter finding contrasts with the assumption that in Tangier disease vessel walls are not a site of lipid storage: probably the vasa nervorum are different, in this respect, from other vessels, because of the intense lipid metabolism of the nervous tissue. Thus we suggest that involvement of vasa nervorum in Tangier disease may be more important than previously suspected, possibly playing a role in the causation of neuropathy.
