ABSTRACT
Juvenile parkinsonism (JP) is characterized by the clinical manifestation of Parkinson syndrome before the age of 21 years old. This entity is often associated with genetic mutations. After all the possibilities of clinical treatment have been exhausted, surgical treatment is recommended, performed via deep brain stimulation (DBS) in the subthalamic nucleus (STN) or in the internal segment of the globus pallidus (GPi). The present study aimed to report the case of a patient with JP who underwent DBS in the STN with good clinical response. Neuromodulation via DBS is an option for the treatment of JP. However, since this entity is very rare, and even more peculiar when treated surgically, more studies are necessary to evaluate DBS used to control refractory manifestations and levodopa-induced dyskinesia, as well as surgical complications that may occur, aiming to gather more knowledge of the surgical management of JP. Despite the dysarthria after the DBS, the patient presented a satisfactory response regarding the symptoms, corroborated by the Parkinson's Disease Questionnaire (PDQ-39) score, which was 61.19% before the procedure, and decreased to 21.05% 14 months after the DBS.

As principais causas de tremor em pacientes atendidos na Atenção Primária à Saúde são: exacerbação de tremor fisiológico, tremor essencial (acomete 5% da população acima de 40 anos) e as síndromes parkinsonianas. É importante definir corretamente sua origem, pois o tratamento e o prognóstico são variados. Esta guia apresenta informação que orienta a conduta para casos de tremor e síndromes parkinsonianas no contexto da Atenção Primária à Saúde, incluindo: etiologia do tremor e síndromes parkinsonianas, avaliação clínica, tipos de tremor, sintomas cardinais de parkinsonismo, medicamentos indutores, fluxograma de avaliação do tremor, exames complementares, tratamento do tremor essencial e doença de parkinson, encaminhamento para serviço especializado.

Background & objectives: Stem cell therapy has been considered as an ideal option for the treatment of Parkinson’s disease. Murine embryonic stem cells (mESCs)-derived dopaminergic (DA) neurons may substitute the degenerated neurons in the brain. In this study we generated highly enriched cultures of neural progenitors from mESCs and grafted them into the striatum of Parkinsonian rats to evaluate their ability to improve impaired function. Methods: An animal model was developed for Parkinson’s disease in rats, using 6- hydroxy dopamine. The animals were divided into two groups: (i) the control group treated with culture medium only, and (ii) the experimental group, which was treated with a murine ESC cell-line (CCE). Transplanted cells were labelled with bromodeoxyuridine (BrdU), exposed to retinoic acid and then engrafted within the striatum of the rat model. Results: Treated ES cells by retinoic acid were found to relieve apomorphine-induced asymmetric motor behaviour. Immunohistochemistry results revealed tyrosine hydroxlase immunoreactivity in engrafted cells 15 days after transplantation. Further, the ultrastructural examination along with cresyl violet staining confirmed that the cells gained neuronal and glial appearance. Interpretation & conclusions: Our data demonstrate that retinoic acid treatment and transplanting ESC cells to the lessioned brain can lead to the generation of putative dopaminergic neurons and functional recovery in parkinsonian rat model with.
