Esclerose lateral amiotrófica: considerações sobre critérios diagnósticos
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder, compromising the motor neuron, characterized by progressive muscle weakness, with reserved prognosis. The diagnosis is based on inclusion and exclusion clinical criteria, since there is no specific confirmation test. The objective of this research is to critically examine the main diagnosis instrument - El Escorial revisited, from the World Federation of Neurology (1998). Of the 540 patients with initial ALS diagnosis, either probable or definite, seen at UNIFESP-EPM, 190 underwent thorough investigation, following regular clinical and therapeutic treatment for over two years. Thirty patients (15.78%) had their diagnosis completely changed. The false-positive diagnoses were related to: early age, clinical presentation of symmetry, weakness greater than atrophy, symptomatic exacerbation. In addition, three patients with myasthenia gravis developed framework for ALS, suggesting the post-synaptic disability as a sign of early disease.Esclerose lateral amiotrófica (ELA) é uma doença neurodegenerativa, que compromete o neurônio motor, caracterizada por fraqueza muscular progressiva, com prognóstico reservado.

O objetivo desta pesquisa é analisar criticamente o instrumento de diagnóstico principal - El Escorial revisited, da Federação Mundial de Neurologia (1998). Dos 540 pacientes com diagnóstico inicial de ELA, seja provável ou definitiva, vistos pela UNIFESP-EPM, 190 foram submetidos a investigação aprofundada, após tratamento clínico e terapêutico regular há mais de dois anos. Trinta pacientes (15,78%) tiveram seu diagnóstico mudado completamente. Os diagnósticos falso-positivos foram relacionados à idade precoce, a apresentação clínica da simetria, a fraqueza superior a atrofia, exacerbação sintomática. Além disso, três pacientes com miastenia gravis desenvolveram quadro de ELA, sugerindo a lesão pós-sináptica como um sinal precoce da doença.Universidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) Department of Neurology and NeurosurgeryUNIFESP, EPM, Department of Neurology and NeurosurgerySciEL
Is positive communication sufficient to modulate procedural pain and anxiety in the emergency room? A randomized controlled trial.
Research suggests that therapeutic communication could enhance patient comfort during medical procedures. Few studies have been conducted in clinical settings, with adequate blinding. Our hypothesis was that a positive message could lead to analgesia and anxiolysis, and that this effect would be enhanced by an empathetic interaction with the nurse performing the procedure, compared to an audio-taped message. This study aimed to modulate the contents and delivery vector of a message regarding peripheral intravenous catheter (PIC) placement in the emergency room (ER).
This study was a 2 + 2 randomized controlled trial registered on clinicaltrials.gov (NCT03502655). A positive versus standard message was delivered through audio tape (double blind) in the first phase (N = 131) and through the nurse placing the catheter (single blind) in the second phase (N = 120).
By design, low practitioner empathic behavior was observed in the first phase (median 1 out of 5 points). In the second phase, higher empathic behavior was observed in the positive than in the standard message (median 2 vs. 3, p < 0.001). Contrary to our hypothesis, the intervention did not affect pain nor anxiety reports due to PIC placement in either phase (all p values>0.2).
The positive communication intervention did not impact pain nor anxiety reports following PIC. There might have been a floor effect, with low PIC pain ratings in a context of moderate pain due to the presenting condition. Hence, such a therapeutic communication intervention might not be sufficient to modulate a mild procedural pain in the ER

Congenital muscular dystrophy: a clinical report on 17 patients
We concur with the idea that congenital muscular dystrophy (CMD) is a distinct clinical entity, and report 17 patients (2 negroes and 15 whites; 12M and 5 F; median age 6 years, range 1 to 24 years) with genetic, clinical, laboratorial, electrophysiological and histochemical studies. All our cases have an inheritance compatible with an autosomal recessive pattern. A decrease in fetal movements was reported by 57% of the mothers, generalized hypotonia at birth was present in 82%, limb girdle and neck weakness, absent or decreased deep tendon reflexes, and limb contractures were present in all. Severe muscular wasting was found in 41%. Calf pseudo-hypertrophy was observed in one patient. A patient was severely mentally retarded and another was borderline. During a 30-month follow-up, the muscle weakness of the majority remained essentially unchanged but the degree of motor activity deteriorated and was proportional to the worsening of the limb contractures. Serum CK levels were normal or increased to a maximum of 8 times. The electromyogram was myopathic in 74%, neurogenic in 13% and normal in 13%. CT scans showed a symmetrical white matter hipodensity in the hemispheres in 8 cases. All but 5 patients were operated upon to release the limb contractures and all were submitted to physical therapy. The contractures recurred in 4 patients submitted to surgery and were probably related to the cessation of physical therapy.Descrevemos 17 pacientes (12m, 5f) com idades que variaram de 1 a 24 anos (mediana 6 anos) com distrofia muscular congênita (DMC), que foram estudados do ponto de vista genético, clínico, laboratorial, eletrofisiológico e anátomo-patológico. A apresentação segundo a herança foi da forma esporádica (76,5%) ou possivelmente autossômica recessiva (23,5%). A diminuição da movimentação fetal intra-uterina foi referida em 57% dos casos, hipotonia neonatal em 82% e retardo no desenvolvimento motor em 88,2%. Fraqueza muscular, diminuição dos reflexos profundos e contraturas articulares estavam presentes em todos os casos. A piora na função motora estava muito relacionada ao aumento ou aparecimento de novas retrações articulares. A CK nunca ultrapassou valores acima de 8 vezes o normal. O ENMG foi de padrão miopático em 73,3%, neuropático em 13,3% e normal em 13,3% dos casos. Aspectos tomográficos com hipodensidade da substância branca subcortical foram vistos em 8 casos. Ao tratamento impôs-se fisioterapia adequada e cirurgia corretiva das deformidades articulares. Novas contraturas desenvolveram-se mais tarde e estavam relacionadas freqüentemente a fisioterapia insuficiente.Escola Paulista de MedicinaUNIFESP, EPMSciEL
