Knowledge and Practical Attitudes of Surgeons-Dentists of Bamako District Facing the Septum Syndrome

Objective: To determine the knowledge and attitude of dental surgeons in Bamako regarding the management of septal syndromes. Material and Methods: It was a crosssectional and descriptive study conducted in the Bamako District, Mali. The following variables were collected: sociodemographic, training, knowledge of septal syndrome, therapeutic decisions and treatment. The data was collected from a survey sheet and processed by Epi-info Software version 3.5.3 and by the language R. Results: A total of 67 professionals participated in this study, of which 88.1% were men. Seventy-six point one percent of the Dental Surgeons have recognized septum syndrome as an emergency. The management of the emergency, followed by the completion of the comprehensive care later represents the attitude of 71.6% of the dentists. Sixty-four point two percent of dentists remove irritating elements under gingival, 80.6% prescribe an antiinflammatory, 38.8% prescribe chlorhexidine gel and 26.9% reconstruct the point of contact. Conclusion: This study demonstrates that Dental Surgeons in general have adequate average knowledge and attitude for their management of septal syndrome.

De Morsier syndrome associated with periventricular nodular heterotopia: case reporte

INTRODUCTION: Septo-optic dysplasia (De Morsier syndrome) is defined as the association between optic nerve hypoplasia, midline central nervous system malformations and pituitary dysfunction. CASE REPORT: Third child born to nonconsanguineous parents, female, adequate pre-natal medical care, cesarean term delivery due to breech presentation, Apgar score 3 at the first minute and 8 at 5 minutes, symptomatic hypoglycemia at 18 hours. Neurological follow-up identified a delay in acquisition of motor and language developmental milestones. Epileptic generalized seizures began at 12 months and were controlled with phenobarbital. EEG was normal. MRI revealed agenesis of the pituitary stalk, hypoplasia of the optic chiasm and periventricular nodular heterotopia. Ophthalmologic evaluation showed bilateral optic disk hypoplasia. Endocrine function laboratory tests revealed primary hypothyroidism and hyperprolactinemia. CONCLUSION: The relevance of this case report relies on its uniqueness, since periventricular heterotopia had not been described in association with septo-optic dysplasia until 2006.

INTRODUÇÃO: Displasia septo-óptica (síndrome de De Morsier) é definida como a associação entre hipoplasia do nervo óptico, malformações de linha média do sistema nervoso central e disfunção pituitária. RELATO DE CASO: Terceiro filho, pais não consangüíneos, sexo feminino, pré-natal adequado, parto cesário a termo por apresentação pélvica, Apgar 3 no primeiro minuto e 8 no quinto minuto, hipoglicemia sintomática com 18 horas de vida. Durante o acompanhamento neurológico identificou-se atraso na aquisição dos marcos de desenvolvimento motor e linguagem. Crises epilépticas generalizadas iniciaram com 12 meses de vida sendo controladas com fenobarbital. EEG era normal. Ressonância magnética revelou agenesia de haste pituitária, hipoplasia de quiasma óptico e heterotopia nodular periventricular. Avaliação oftalmológica demonstrou hipoplasia bilateral de disco óptico. Investigação da função endócrina revelou hipotireoidismo primário e hiperprolactinemia. CONCLUSÃO: A relevância deste relato reside em seu ineditismo, já que heterotopia periventricular não havia sido descrita em associação com displasia septo-óptica até 2006.

Septo-optic dysplasia plus: case report

Septo-optic dysplasia (SOD) is a syndrome composed by optic nerve and septum pellucidum dysgenesis. It has been classified into two subsets according to the embryogenesis and the neuropathological findings. Basically, the difference between these two groups is the presence or not of schizencephaly. The term SOD-Plus was recently proposed to describe SOD associated with cortical dysplasia. We report a 6-month-old female patient who presented absent visual fixation since 4 months of age and delayed psychomotor development. Neurological examination demonstrated spastic left hemiparesis and ophtalmological evaluation revealed bilateral optic disc hypoplasia. The head computed tomography (CT) scan showed absence of the septum pellucidum, ventricular asymmetry and schizencephaly. The magnetic resonance imaging (MRI) showed complete absence of the septum pellucidum associated to optic nerves and chiasma atrophy, schizencephaly and cortical dysplasia. The patient underwent an evoked potential examination with flash stimulation, which revealed bilateral absence of cortical evoked potential. She was referred to visual stimulation and physiotherapy. We emphasize the neuroimaging of this syndrome and stress the importance of the clinical investigation for patients with septum pellucidum dysgenesis on MRI or CT scans
