Zika virus (ZIKV) is now considered an emerging flavivirosis, with a first large outbreak registered in the Yap Islands in 2007. In 2013, a new outbreak was reported in the French Polynesia, with associated cases of neurological complications including Guillain-Barré syndrome (GBS). The incidence of GBS has increased in Brazil since 2015, what is speculated to be secondary to the ZIKV infection outbreak. The gold-standard test for detection of acute ZIKV infection is the polymerase-chain reaction technique, an essay largely unavailable in Brazil. The diagnosis of GBS is feasible even in resource-limited areas using the criteria proposed by the GBS Classification Group, which is based solely on clinical grounds. Further understanding on the relationship of ZIKV with neurological complications is a research urgency.

Nerve biopsy specimens from 53 patients with leprosy and neuropathy were taken from the sural, the dorsal branch of the ulnar, or the superficial radial nerves and processed for light and electron microscopy. There was inflammation in 40 cases (75%), 7 with a granulomatous reaction, various stages of fibrosis in 35 (66%), and endoneurial vascular neoformation in 7. In two cases, small focal infarcts were associated with marked endoneurial inflammation compressing the vessels, in addition to endoneurial lymphocytic vasculitis. Most had an axonal neuropathy of varying degree, some with total fibre loss, others with predominant small myelinated and unmyelinated fibre loss. Signs of demyelination and remyelination were the main findings in 9 cases (17%). Bacilli were present in endothelial, perineurial, Schwann cells and in macrophages. On two occasions, they lost their alcohol acid resistance, were suspected in semithin sections, and confirmed ultrastructurally. The biopsy was decisive for the diagnosis of leprosy in 15 cases (28%), most without skin lesions. We evaluated the effectiveness of the treatment in 20 (37.7%), 12 without and 8 with bacilli, despite negativity in the skin. The diagnosis of leprosy based on skin lesions was confirmed with the nerve biopsy in 9 cases, 6 had an inflammatory neuropathy suggestive of leprosy in the absence of bacilli, and 3 had nonspecific changes in the sural nerve since the neuropathy was in the upper limbs. We conclude that nerve biopsy is indicated for the diagnosis of leprosy in cases without clinically visible skin lesions and to evaluate the effectiveness of the treatment. In these cases the ultrastructural studies are important for recognition of the bacilli. Vascular lesions may play an important role in the progression of the nerve damage, including the occurrence of focal nerve infarcts which, to our knowledge, have not been previously reported in association with leprosy.

A need still exists to determine the clinical and neurophysiological characteristics of leprosy neuropathy at distinct times of the disease by different methods that measure the various nerve fiber functions. A prospective clinical study was performed with 10 paucibacillary (PB) and 12 multibacillary (MB) patients evaluated at diagnosis and one year after cessation of multidrug therapy (MDT). Peripheral nerve function was assessed clinically and by means of the sympathetic skin response, skin vasomotor reflex, and nerve conduction study (NCS). At diagnosis, 73% of the total 22 patients had nerve function impairment (NFI). Autonomic function (χ2= 5.5, P= 0.019) and NCS (χ2= 7.765, P= 0.01) were significantly more altered in MB than PB patients. At final evaluation, NFI of the MB patients had worsened, especially among the six who had leprosy reaction. As the NFI of PB patients showed improvement, a significant difference between the two groups (χ2= 12.320, P= 0.001) was observed. A high prevalence of neuropathy was observed in newly diagnosed patients. Associating different tests with a thorough clinical neurological evaluation increases detection rates.

A esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa progressiva do sistema nervoso central, que evolui causando atrofia progressiva da musculatura respiratória e dos membros além de sintomas de origem bulbar como disartria e disfagia, resultando em morte ou ventilação mecânica permanente. Objetivo. Apresentar as principais alterações da fonação e da deglutição na ELA, disponíveis na literatura vigente. Método. Neste estudo de revisão da literatura, foi realizada uma busca nas principais bases de dados LILACS e SciELO, com as seguintes palavras-chave: esclerose amiotrófica lateral, disfagia, disfonia, disartria, fonoterapia, no período compreendido entre 1977 e 2006. Resultados. A aplicação de diferentes manobras fonoaudiológicas mostrou ser importante para a reabilitação de pacientes com ELA. O fonoaudiólogo instrui o paciente como preservar e/ou minimizar os problemas de deglutição e fonação, na medida em que a doença progride. Conclusão. A detecção precoce desses distúrbios permite aos fonoaudiólogos avaliar objetivamente os prejuizos funcionais e traçar metas realistas de reabilitação. Os resultados atentam para o desenvolvimento de um protocolo de pesquisa da ELA do ponto de vista fonoaudiológico, devido à escassez de material encontrado.
