Polyglucosan bodies in brain tissue: a systematic study.

The relation between age, sex and presence of polyglucosan bodies in the brain has been systematically studied in 64 patients who did not suffer from neurological brain disorders and in 2 cases with Lafora's disease. In the normal brain the number of polyglucosan bodies is related to increasing age. Under the age of 40, polyglucosan bodies can be found sporadically in cases without a neurological disorder, but in the cases of Lafora's disease their number is uncomparatively higher.

X-linked ataxia, weakness, deafness, and loss of vision in early childhood with a fatal course.

An X-linked recessive disease with, in almost all patients, a fatal course in early childhood, occurring in a five-generation family is described. The 12 affected boys had early-onset floppiness, ataxia, liability to infections especially of the upper respiratory tract, deafness, and later, a flaccid tetraplegia and areflexia. Eleven boys died before the age of 5 years.

Histologic factors in the grading and prognosis of astrocytoma grade I-IV.

The prognostic value of histologic or cytologic features were examined in 317 patients with an astrocytic glioma. Of 46 features examined 7 morphologic characteristics of nucleus and 5 of mesenchyma correlated well with grading according to Kernohan. The morphological characteristics of nucleus are cellularity, atypical nuclei, polymorphism, multinucleated cells, hyperchromasia, gigantic nuclei and mitosis.

Long-lasting epidural sensory blockade by n-butyl-p-aminobenzoate in the terminally ill intractable cancer pain patient.

An aqueous suspension of n-butyl-p-aminobenzoate (BAB), a highly lipid-soluble congener of benzocaine, was applied epidurally in terminally ill cancer patients with intractable pain. The suspension consisted of 10% BAB and 0.025% of the nonionic surfactant polysorbate 80 in 0.
