          Abstract

          Introduction: Belly Dancer’s syndrome is a rare movement disorder characterized by involuntary contractions of the diaphragm, causing abnormal movements in the abdominal wall. Many different causes were described such as trauma, infections, metabolic disorders and drug ingestion. Sometimes the cause remains uncertain and a psychogenic disturb has been suggested in others. Case report: A 14-year-old female presented with episodic involuntary movements of the abdomen that had started one week after falling. Besides these abnormal movements, physical examination was unremarkable. Belly Dancer’s syndrome was suspected and the neuroimaging revealed C3 and C4 nerve root injuries and several vertebral lesions. The treatment performed included oral chlorpromazine, immobilization with Jewett vest, rest and physiotherapy, with remarkable symptoms improvement. Discussion: This clinical presentation of this syndrome is quite unusual, which may lead to late diagnosis or ineffective treatments. We report a case of traumatic Belly Dancer’s syndrome that improved significantly with stabilization of the lesion.

          Introdução: A síndrome de Belly Dancer é um distúrbio raro do movimento, caracterizado por contrações involuntárias do diafragma, causando movimentos anormais da parede abdominal. As várias causas descritas incluem trauma, infeções, distúrbios metabólicos ou ingestão de drogas. A causa pode permanecer incerta ou ser atribuída a distúrbios psicogénicos. Caso Clínico: Adolescente de 14 anos de idade, sexo feminino, recorreu ao serviço de urgência por movimentos abdominais involuntários, com início uma semana após queda. Apesar desses movimentos anormais, o exame físico era normal. Colocada a hipótese de síndrome de Belly Dancer, realizou neuroimagem que revelou várias lesões vertebrais, incluindo a nível das raízes nervosas de C3 e C4. O tratamento incluiu clorpromazina oral, imobilização com colete de Jewett, repouso e fisioterapia, com melhoria dos sintomas. Discussão: Pela raridade e apresentação clínica incomum, o diagnóstico e respetivo tratamento podem ser tardios. Relatamos um caso com origem traumática e melhoria significativa após estabilização da lesão.

          Diaphragmatic flutter, the moving umbilicus syndrome, and "belly dancer's" dyskinesia.

          Five patients presenting with focal abnormal involuntary movements of the abdominal wall are described. One was shown to have diaphragmatic flutter, which may represent a variant of the palatal myoclonus syndrome. The other four had writhing movements and contractions of the abdominal wall at frequencies of approximately 30 per minute. In two of the latter cases, these abdominal movements were profoundly influenced by respiratory manoeuvres. They were quite unlike the movements of spinal myoclonus or axial torsion dystonia. None of the patients were taking drugs that might have provoked their abnormal movements, or had any other evidence of neurological deficit. No cause was established in any of the cases.

            Case series of painful legs and moving toes: clinical and electrophysiologic observations.

            We present a retrospective review of cases of painful legs and moving toes (PLMT) syndrome. Out of 4,780 database patients with movement disorders diagnosed at Mayo Clinic Arizona from 1996 to 2006, we identified 14 cases of PLMT and its variants (6 men, 8 women). Ages ranged from 25 to 84 years (mean, 69 years). Movements were bilateral in 12 and unilateral in 2. Pain preceding the movements was most commonly burning; movements consisted of flexion/extension, abduction/adduction, fanning, or clawing of toes, fingers, and sometimes the foot or hand. The most common predisposing factors were neuropathy and radiculopathy. Surface electromyography showed movements suggestive of both chorea and dystonia. Movements were partially suppressible and were diminished but still apparent during light sleep. GABAergic agents were most effective in controlling the pain and the movements.
