Periodic hypersomnia, congenital ectodermal disorders and multiple exostosis

Hipersônia periódica, malformações ectodérmicas e exostose múltipla

Abstracts

A case of periodic hypersomnia in an 11-year-old female with the unique features of mental deficiency, incontinentia pigmenti, acanthosis nigricans and hereditary multiple exostosis (diaphysial aclasis) is reported. The clinical, Polysomnographic and Multiple Sleep Latency test features of this case with a follow up of seven years are consistent with a diagnosis of periodic (intermittent) excessive somnolence. The unique presentation, however, does differ from Kleine-Levin syndrome and suggests a relationship between the predominantly ectodermal, congenital disorders and the sleep-wake, pattern dysfunction.


Relata-se um caso de sonolência excessiva periódica acompanhada de hiperfagia, com início na segunda década, documentado clinicamente, em tragados polissonográficos de noite inteira e no teste das Latências Múltiplas do Sono. Apresenta características que o distinguem da síndrome de Kleine-Levin, a saber, a ocorrência no sexo feminino, deficiência mental, incontinência pigmentar, acantose nigricans e exostose múltipla.

SUMMARY

A case of periodic hypersomnia in an 11-year-old female with the unique features of mental deficiency, incontinentia pigmenti, acanthosis nigricans and hereditary multiple exostosis (diaphysial aclasis) is reported. The clinical, Polysomnographic and Multiple Sleep Latency test features of this case with a follow up of seven years are consistent with a diagnosis of periodic (intermittent) excessive somnolence. The unique presentation, however, does differ from Kleine-Levin syndrome and suggests a relationship between the predominantly ectodermal, congenital disorders and the sleep-wake, pattern dysfunction.

RESUMO

Relata-se um caso de sonolência excessiva periódica acompanhada de hiperfagia, com início na segunda década, documentado clinicamente, em tragados polissonográficos de noite inteira e no teste das Latências Múltiplas do Sono. Apresenta características que o distinguem da síndrome de Kleine-Levin, a saber, a ocorrência no sexo feminino, deficiência mental, incontinência pigmentar, acantose nigricans e exostose múltipla.
