- Home-based Rehabilitation With A Novel Digital Biofeedback System versus Conventional In-person Rehabilitation after Total Knee Replacement: a feasibility studyPublication . Correia, F.; Nogueira, A.; Magalhães, I.; Guimarães, J.; Moreira, M.; Barradas, I.; Teixeira, L.; Tulha, J.; Seabra, R.; Lains, J.; Bento, V.In-person home-based rehabilitation and telerehabilitation can be as effective as clinic-based rehabilitation after total knee arthroplasty (TKA), but require heavy logistics and are highly dependent on human supervision. New technologies that allow independent home-based rehabilitation without constant human supervision may help solve this problem. This was a single-center, feasibility study comparing a digital biofeedback system that meets these needs against conventional in-person home-based rehabilitation after TKA over an 8-week program. Primary outcome was the change in the Timed Up and Go score between the end of the program and baseline. Fifty-nine patients completed the study (30 experimental group; 29 conventional rehabilitation). The study demonstrated a superiority of the experimental group for all outcomes. Adverse events were similar in both groups. This is the first study to demonstrate that a digital rehabilitation solution can achieve better outcomes than conventional in-person rehabilitation, while less demanding in terms of human resources.
- Homozygosity mapping of Portuguese and Japanese forms of ataxia-oculomotor apraxia to 9p13, and evidence for genetic heterogeneity.Publication . Moreira, M.; Barbot, C.; Tachi, N.; Kozuka, N.; Mendonça, P.; Barros, J.; Coutinho, P.; Sequeiros, J.; Koenig, M.Abstract Ataxia with oculomotor apraxia (AOA) is characterized by early-onset cerebellar ataxia, ocular apraxia, early areflexia, late peripheral neuropathy, slow progression, severe motor handicap, and absence of both telangiectasias and immunodeficiency. We studied 13 Portuguese families with AOA and found that the two largest families show linkage to 9p, with LOD scores of 4.13 and 3.82, respectively, at a recombination fraction of 0. These and three smaller families, all from northern Portugal, showed homozygosity and haplotype sharing over a 2-cM region on 9p13, demonstrating the existence of both a founding event and linkage to this locus, AOA1, in the five families. Three other families were excluded from this locus, demonstrating nonallelic heterogeneity in AOA. Early-onset cerebellar ataxia with hypoalbuminemia (EOCA-HA), so far described only in Japan, is characterized by marked cerebellar atrophy, peripheral neuropathy, mental retardation, and, occasionally, oculomotor apraxia. Two unrelated Japanese families with EOCA-HA were analyzed and appeared to show linkage to the AOA1 locus. Subsequently, hypoalbuminemia was found in all five Portuguese patients with AOA1 with a long disease duration, suggesting that AOA1 and EOCA-HA correspond to the same entity that accounts for a significant proportion of all recessive ataxias. The narrow localization of AOA1 should prompt the identification of the defective gene.
- Recessive ataxia with ocular apraxia: review of 22 Portuguese patients.Publication . Barbot, C.; Coutinho, P.; Chorão, R.; Ferreira, C.; Barros, J.; Fineza, I.; Dias, K.; Monteiro, J.; Guimarães, A.; Mendonça, P.; Moreira, M.; Sequeiros, J.Abstract BACKGROUND: The recessive ataxias are a heterogeneous group of neurodegenerative disorders characterized by cerebellar ataxia associated with a number of different neurologic, ophthalmologic, or general signs. They are often difficult to classify in clinical terms, except for Friedreich ataxia, ataxia-telangiectasia, and a relatively small group of rare conditions for which the molecular basis has already been defined. OBJECTIVES: To study the clinical presentation and to define diagnostic criteria in a group of Portuguese patients with ataxia and ocular apraxia, an autosomal recessive form without the essential clinical and laboratory features of ataxia-telangiectasia. PATIENTS AND METHODS: We reviewed 22 patients in 11 kindreds, identified through a systematic survey of hereditary ataxias being conducted in Portugal. RESULTS: Age at onset ranged from 1 to 15 years, with a mean of 4.7 years. The duration of symptoms at the time of last examination varied from 5 to 58 years. All patients presented with progressive cerebellar ataxia, the characteristic ocular apraxia, and a peripheral neuropathy. Associated neurologic signs included dystonia, scoliosis, and pes cavus. Magnetic resonance imaging was performed in 16 patients, all of whom showed cerebellar atrophy. CONCLUSIONS: Ataxia with ocular apraxia may be more frequent than postulated before, and may be identified clinically using the following criteria: (1) autosomal recessive transmission; (2) early onset (for most patients in early childhood); (3) combination of cerebellar ataxia, ocular apraxia, and early areflexia, with later appearance of the full picture of peripheral neuropathy; (4) absence of mental retardation, telangiectasia, and immunodeficiency; and (5) the possibility of a long survival, although with severe motor handicap.
- Transfusão feto-fetal e transfusão feto-maternaPublication . Rodrigues, S.; Rocha, A.; Inocêncio, G.; Moreira, M.; Saraiva, J.; Dias, C.; Rodrigues, M.Introdução: Os autores descrevem um caso de transfusão feto materna (TFM) significativa com repercussão fetal, após ablação de anastomoses vasculares placentares, por síndrome de transfusão feto fetal (STFF). Caso Clínico:31 anos, saudável, primigesta, gravidez espontânea gemelar, monocoriónica biamniótica. A ecografia do 1º trimestre, efetuada às 12 semanas, mostrava concordância dos valores do comprimento crânio caudal (CCC), mas discordância dos valores da medida da translucência da nuca (TN). O rastreio combinado do 1º trimestre foi negativo. Às 16 semanas foi diagnosticado um STFF – estadio II/III de Quintero. A amniocentese revelou um cariótipo normal 46, XY no feto dador e um cariótipo anormal 47, XYY no feto receptor. Às 17 semanas foi efetuada ablação laser das anastomoses vasculares placentares, tendo ocorrido a morte do feto dador às 18 semanas. Às 22 semanas foi diagnosticada anemia fetal, por TFM, confirmada por citometria de fluxo. Às 26 semanas foi constatada dilatação de ansa intestinal - suspeita de atrésia intestinal. Parto por cesariana às 37 semanas. RN: sexo masculino, 2660g, Índice de Apgar 5/8/10. Confirmada atrésia ileal tipo II e efetuada enterectomia segmentar. Evolução clínica favorável. Conclusão: Trata-se de um caso de transfusão feto-fetal seguido de transfusão feto-materna, com atrésia intestinal em provável relação com anemia fetal, em feto com cromossomopatia
