OBJECTIVES We investigated the relationship between non-syndromic cleft lip/palate (NSCLP) and polymorphisms in methylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), methionine synthase reductase (MTRR), and RFC1, as well as the corresponding interactions with environmental factors. SUBJECTS AND METHODS One hundred and forty NSCLP(More)
INTRODUCTION Autonomic epilepsy is a rare entity that results from an epileptogenic focus involving certain structures belonging to the autonomous nervous system; it is characterised by the occurrence of convulsive seizures that consist in autonomic phenomena. CASE REPORT We report the case of a 28-year-old female patient who suffered paroxysmal episodes(More)
Favism is an acute hemolytic syndrome occurring in glucose-6-phosphate dehydrogenase (G6PD) deficient individuals after the consumption of fava beans. The authors report the clinical case of a 16 year-old boy admitted to hospital with an acute hemolytic episode after the ingestion of fava beans. Complementary studies revealed G6PD deficiency. A study of the(More)
OBJECTIVE The aim of this study was to investigate the contribution of 6 polymorphic variants of the MSX1 gene in non-syndromic cleft lip and/or palate (NSCL/P). METHODS Three hundred and fifty-eight individuals (158 NSCL/P cases and 200 controls) were genotyped by TaqMan allelic discrimination using predesigned SNP assays. Statistical analyses were(More)
The aim of this investigation was to compare the clinical performance of a glass ionomer cement (GIC) with a composite resin when used for direct bonding of standard edgewise orthodontic brackets. Fourteen patients (10 females, four males), in whom 242 teeth were bonded with brackets, were divided into two groups: GIC (121 teeth) and composite (121 teeth).(More)
OBJECTIVE To evaluate the influence of enamel etching on tensile bond strength of orthodontic brackets bonded with resin-reinforced glass ionomer cement. MATERIALS AND METHODS The sample group consisted of 15 patients who had indications for extraction of four premolars for orthodontic reasons, equally divided into two different groups according to(More)
