Title:Aspectos cirurgicos da caseóse dos nervos na lepra / Surgical aspects of caseous nerves in leprosy
Source:Rev. Lepr. São Paulo;1(3):146-184, Maio 1934. ^bilus.
Abstract:Baseado em 10 casos de observa‡„o pessoal, o A. faz um estudo, sob o ponto de vista cirurgico, da caseose dos nervos na lepra. Come‡a salientando que focaliza o assumpto apenas debaixo dos seus aspectos cirurgicos, pois que os mesmos casos e outros mais que n„o lhe foi dado operar ser„o apreciado, na sua fei‡„o clinica e anatomo-patologica, pelos Drs Nelson de Souza Campos e Jos‚ Oria. Acha necessario, por‚m, dizer em poucas palavras o que ‚ a afec‡„o. Na nevrite leprosa, os nervos perifericos aumentam de volume, dando  s vezes engorgitamentos em rosario; em geral sobrevem um processo de fibrose; raras vezes, entretanto, talvez em consequencia de um maior poder defensivo do organismo, com destrui‡„o dos germes e decorrente forma‡„o de substƒncias toxicas, o que se verifica ‚ a necrose, seguida de caseose de coagula‡„o e posterior liquefac‡„o, processo esse circundade por tecido granulomatoso, com fibroblastos, fibrilas colagenas, gigantocitos, linfocitos, plasmocitos, histiocitos e vasos neoformados, havendo, de regra, ausˆncia deMycobacterium leprae. Esse f¢com de caseose, que se forma de prefˆrencia no endonervo, faz saliencia no espinonervo e da¡ progride em dire‡„o aos tecidos superficiais, procurando a pele, por onde em tempo, mais ou menos remoto, se esvasia espontaneamente...

Title:Near-nerve potential in lepromatous leprosy ..-
Source:s.l; s.n; 2003. 4 p. ilus, tab.
Abstract:In leprosy, sensory action potentials (SAPs) may be normal in spite of clinical sensory loss. This may result from the early involvement of small nerve fibers, which have potentials that are not detected in routine studies. To evaluate this possibility, we used a near-nerve recording technique that records potentials from nerve fibers as small as 4-6 microm in diameter. We hypothesized that this technique might increase the sensitivity of nerve conduction studies in detecting leprosy neuropathy. We found the technique to be useful for recording conduction abnormalities in recently diagnosed patients, including those with preserved sensation, suggesting that axonal loss may be the underlying mechanism. Contrary to our hypothesis, however, recording the late SAP components did not improve the sensitivity of nerve conduction studies. We suggest that the late components having normal conduction velocities may be generated by either regenerating or remyelinating abnormal fibers, which have an electrophysiological behavior similar to that of normal 4-6-microm-diameter fibers.

Title:Study of the evolution of nerve damage in leprosy. Part I--Lesions of the index branch of the radial cutaneous nerve in early leprosyStudy of evolution of nerve damage in leprosy. Part II--Observations on the index branch of the radial cutaneous nerve in contacts of leprosy ..-
Source:s.l; s.n; jan. 1980. 14 p. tab, graf, ilus.
Abstract:A total of six index finger branch of the radial cutaneous (IRC) nerves from three BL, two BB and one BT cases of leprosy, with less than 6 months history of disease were subjected for nerve conduction velocity (NCV) studies followed by biopsy. The biopsy was divided into three parts and subjected for light microscopy quantitative histology, electron-microscopy and fibre tease studies. The nerves revealed a slight reduction in NCV and a varying degree of segmental demyelination ranging from 10% to 35%. The earliest changes observed were the thickening and proliferation of Schwann cell processes of the unmyelinated fibres and degeneration of their axons regardless of the type of leprosy.(AU) A total of 35 contacts from 20 families of lepromatous index cases were screened clinically. All of them were subjected for nerve conduction velocity (NCV) studies of both left and right index branch of the radial cutaneous (IRC) nerve. Fifteen of these nerves were biopsied. Out of 15 IRC nerves biopsied 10 had slightly reduced average NCV values and 5 were normal. Four nerves out of 10 where average NCV was reduced and 1 nerve out of 5 where NCV was normal showed significant ultrastructural changes and higher percentage of segmental demyelination (10%--13%). There was a striking similarity between the changes seen in the IRC nerves of early cases of leprosy and of contacts.(AU).
