RESUMO
Weight loss dietary supplements are used with some frequency by an increasingly overweight population. Some products are not adequately regulated and may pose potential health risks. We report two new cases of acute toxic leukoencephalopathy (ATL) due to the use of a supplement marketed as a thermogenic weight loss aid. ATL is a heterogeneous clinic-radiological entity that has been associated with various compounds, such as chemotherapeutic drugs and immunomodulators. It is characterized by an often reversible periventricular and infratentorial demyelination. The commercialization of non-regulated weight loss products continues to be a health risk in our population.

Amyotrophic lateral sclerosis (ALS) is described as a neurodegenerative disorder. However, neuroinflammation and chemokine expression are prominent pathological finding at sites of injury. Adipsin and adiponectin are molecules that are implicated in the pathogenesis of neurodegenerative and neuroimmune disorders. Adipsin and adiponectin concentrations were determined in the CSF of ALS patients and controls and the relationship of these chemokines with clinical severity and disease duration in ALS was determined. Seventy-seven ALS patients (mean age 49.5 ± 10.4 years) (mean body mass index 23.5 ± 4.5) were included. Twenty patients had bulbar, 53 spinal, and four bulbospinal onset ALS. Median adipsin CSF level was 12,650.94 pg/ml in ALS patients and 3290.98 pg/ml in controls (p < 0.001). Median adiponectin CSF level was 4608 pg/ml in ALS patients and 3453 pg/ml in controls (p = 0.1). No differences were observed in disease duration, progression rate or disease severity. There was a significant positive correlation between adipsin and adiponectin concentrations (r = 0.379, p = 0.01). No correlation with age, body mass index or ALFRS-R score was found. Adipsin was significantly elevated in CSF, suggesting that this chemokine might have a role in ALS pathogenesis. Adiponectin showed a trend towards higher concentrations, but failed to reach statistical significance. Due to the clinical heterogeneity in our cohort, these chemokines do not appear to be associated with disease duration or severity.

ResumenINTRODUCCIÓN: La retinosis pigmentaria es la forma hereditaria y crónica más común de distrofia retiniana. Esta condición se caracteriza inicialmente por la afectación progresiva de los fotorreceptores y, posteriormente, de otras capas de la retina. En la exploración ocular esta situación se traduce como palidez del disco óptico, disminución vascular y depósitos de pigmento en la retina.CASO CLÍNICO: Se presenta el caso de un paciente masculino de 15 años de edad con una historia de 6 meses de evolución caracterizada por ceguera nocturna y disminución de la visión lateral temporal superior en ambos ojos.CONCLUSIONES: Este tipo de padecimiento ocular distrófico, genético y progresivo comienza durante la adolescencia y condiciona una discapacidad visual.
AbstractBACKGROUND: Retinitis pigmentosa is the most common chronic and inherited condition of retinal dystrophy. The progressive involvement of retinal photoreceptors and other layers characterize this condition. This situation results in optic disc pallor and retinal pigment deposition vascular attenuation.CASE REPORT: We present the case of a 15-year-old male with a history of 6 months evolution characterized by night blindness and bilateral impairment of superior temporal vision.CONCLUSIONS: This type of dystrophy is a genetic and progressive eye condition that begins during adolescence and produces visual impairment.
RESUMO
The branchio-oculo-facial syndrome is a dominant autosomic condition with variable expressivity that affects particularly the facial and neck structures by an inadequate development of the first and second branchial arch. It is characterized by malformations of eyes and ears, with distinct facial characteristics. It is associated with alterations in TFAP2A gene. We present a patient with 9 years of age with phenotype of the branchio-oculo-facial syndrome and the presence of 2 new oral manifestations, the bifid uvula and the tongue with partial central cleft, not yet described in this clinical condition.

El síndrome branquio-óculo-facial es una condición autosómica dominante con expresividad variable y que afecta particularmente las estructuras de la cara y cuello por un desarrollo inadecuado del primero y segundo arco branquial; presenta malformaciones de los ojos y oídos, con características faciales distintivas. Está asociado con alteraciones en el gen TFAP2A. Se presenta una paciente de 9 años con fenotipo de síndrome branquio-óculo-facial y la presencia de dos nuevas manifestaciones orales, la úvula bifida y la lengua con hendidura central parcial, no descritas hasta ahora en esta condición clínica.

RESUMO
The vestibular schwannoma is a benign intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve or cranial nerve VIII. It comprises 8-10% of all intracranial neoplasms in adults. It originates in the vestibular portion of the cranial nerve VIII and it is located in the cerebellopontine angle. This disorder is characterized by ipsilateral hearing loss, tinnitus, disturbed sense of balance and altered gait, facial numbness, muscle weakness or ipsilateral paralysis. This report presents the magnetic resonance imaging of a patient with this rare condition.
