ABSTRACT
PURPOSE: The aim of the study was to investigate and analyze bilateral incidence and morphology of complete discoid lateral meniscus (DLM) with possible relation to tears and symptoms in knee joints. MATERIALS AND METHODS: Thirty-eight consecutive patients with symptomatic or already-torn complete DLM on magnetic resonance imaging in a unilateral knee underwent diagnostic arthroscopy on both knee joints upon agreement. The presence and shape of complete DLM as well as presence and pattern of tear were recorded accordingly. RESULTS: In total, 89.5% (34 of 38 patients) showed bilateral complete DLM, and 84.2% yielded bilateralism with identical shape. Cape-slab was the most frequent shape, comprising 68.8% of patients with identically-shaped bilateral DLM overall. Tear patterns were more frequent, in the order of longitudinal, simple horizontal, radial, and degenerative; however, the morphological shape of complete DLM was not significantly related to tear incidence or pattern. Meniscus tears and knee symptoms occurred in the contralateral knee with incidences of 32.4% and 26.5% in patients with bilateral complete DLM, respectively. CONCLUSION: Based on these findings, more aggressive warning on the presence of discoid pathology and the need for evaluation on the contralateral knee should be considered during consultation with patients with symptomatic complete DLM in a unilateral knee in the outpatient clinic.

OBJECTIVE: To determine the prevalence of thoracic musculoskeletal alterations and associated factors in infants born prematurely. METHODS: This was a cross sectional study with infants in the first year of age, born prematurely with birth weight < 2,000 g, who were followed up at the Premature Clinic from February, 2007 to December, 2008. Exclusion criteria were: maj or congenital malformations as defined by the Centers for Disease Control and Prevention (CDC), grade III/IV intraventricular hemorrhage, or periventricular leucomalacia. Physical examinations performed independently by two physiotherapists were used to assess shoulder elevation and thoracic retractions. Comparisons between groups were performed using the chi-squared test or Fisher's exact test for categorical variables, and Mann-Whitney's test or Student's t-test were used for continuous variables. Interobserver reliability between the two physiotherapists was assessed by the kappa coefficient. Variables associated with these thoracic musculoskeletal alterations were studied by univariate and multiple logistic analyses. Statistical differences were considered significant when p < 0.05. This study was approved by the ethical committee of the institution, and parents/guardians signed an informed consent. RESULTS: 121 infants with a gestational age of 31.1 ± 2.8 weeks and birth weight of 1,400 ± 338 g were included. Thoracic alterations were detected by Physiotherapist 1 in 81 (66.9%) infants, and in 83 (68.6%) by Physiotherapist 2 (kappa coefficient = 0.77). By multivariate logistic regression analysis, factors associated with thoracic musculoskeletal alterations were: respiratory distress syndrome (odds ratio [OR] = 3.246, 95% confidence interval [CI]: 1.237-8.732), bronchopulmonary dysplasia (OR = 11.138, 95% CI: 1.339-92.621), and low length/age ratio (OR = 4.571, 95% CI: 1.371-15.242). CONCLUSION: The prevalence of thoracic alterations was high in infants born prematurely, and was associated with pulmonary disease and low length/age ratio.
OBJETIVO: Determinar a prevalência e os fatores associados às alterações torácicas musculoesqueléticas em lactentes nascidos prematuros. MÉTODOS: Estudo transversal com lactentes no primeiro ano de vida, nascidos prematuros com peso < 2000 g e acompanhados em um ambulatório de seguimento de prematuros, de fevereiro/2007 a dezembro/2008. Foram excluídas crianças com malformações maiores definidas pelo CDC ou com hemorragia peri-intraventricular grau III/IV ou leucomalácia periventricular. Duas fisioterapeutas realizaram o exame físico, avaliando, de modo independente, a elevação de ombros e as retracões da caixa torácica. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Instituição, sendo solicitada assinatura do Termo de Consentimento pelos pais. As variáveis numéricas foram comparadas pelo teste t ou Mann-Whitney. O grau de concordância entre as avaliações das fisioterapeutas foi obtido pelo coeficiente kappa e as variáveis associadas às alterações torácicas foram estudadas por regressão logística univariada e múltipla. Considerou-se significante p < 0,05. RESULTADOS: Foram estudados 121 lactentes com idade gestacional de 31,1 ± 2,8 semanas e peso ao nascer de 1400 ± 338 g. A fisioterapeuta 1 detectou alterações torácicas em 81 (66,9%) lactentes e a fisioterapeuta 2 em 83 (68,6%) (coeficiente kappa = 0,77). Os fatores associados às alterações musculoesqueléticas foram: síndrome do desconforto respiratório no período neonatal (OR=3,246; IC 95%: 1,237-8,732), ter apresentado displasia broncopulmonar (OR=11,138; IC 95%: 1,339-92,621) e relação comprimento para a idade alterada (OR=4,571; IC 95%: 1,371-15,242). CONCLUSÃO: A prevalência de alterações torácicas foi alta em lactentes nascidos prematuros e associou-se a doença pulmonar no período neonatal e baixa relação comprimento/idade.

We report a case of an 18-year-old male who presented with watering and inability to close the left eye completely since 6 months and inability to move both eyes outward and to close the mouth since childhood. Ocular, facial, and systemic examination revealed that the patient had bilateral complete lateral rectus and bilateral incomplete medial rectus palsy, left-sided facial nerve paralysis, thickening of lower lip and inability to close the mouth, along with other common musculoskeletal abnormalities. This is a typical presentation of Moebius syndrome which is a very rare congenital neurological disorder characterized by bilateral facial and abducens nerve paralysis. This patient had bilateral incomplete medial rectus palsy which is suggestive of the presence of horizontal gaze palsy or occulomotor nerve involvement as a component of Moebius sequence.
