RESUMEN
Obesity is considered to be a chronic disease associated with early medical complications including: respiratory, cardiovascular, metabolic,psychological and social changes. Over recent decades, there has been a marked increase in the incidence of obesity among the population.Obesity has significant metabolic and systemic immune and inflammatory effects. Bariatric surgery has emerged as a treatment for morbid obesity. Oral changes following bariatric surgery were determined. One man and one woman, with initial Body Mass Indexes of 53-34 and 42-26 kg/m2 respectively, were followed for two years after undergoing Fobi Capella surgery. Dietary complications (frequent vomiting), nutrient deficiencies (iron, vitamin B12, calcium, folic acid and zinc) and xerostomia, sensitivity, and periodontitis were seen in both cases. Demineralization and infiltration of fillings evolved into erosion and an endodontic lesion (case 1) and mobility with consequent tooth loss (case 2). Problems with gingival bleeding, dental caries and dental mobility are directly related to compromising the absorptive area and/or the dietary behaviour of the individual after carrying out bariatric surgery.
A obesidade é considerada uma doença crônica associada a complicações médicas precoces como: alterações respiratórias, cardiovasculares, metabólicas, psíquicas e sociais. Nas últimas décadas, a obesidade tem apresentado um aumento considerável da sua incidência na população. A obesidade apresenta efeitos metabólicos e imunológicos e inflamatórios sistêmicos significativos. A cirurgia bariátrica tem sido visto como um tratamento para obesidade mórbida. Alterações bucais após cirurgia bariátrica foram avaliados. Um homem e uma mulher, com Índices de Massa Corporal iniciais de 53-34 e 42-26 kg/m2, respectivamente, foram acompanhados por dois anos após ser submetidos à cirurgia Fobi Capella. Seqüelas alimentares (vômito freqüente), deficiências de nutrientes (ferro, vitamina B12, cálcio, ácido fólico e zinco) e xerostomia, sensibilidade, e periodontite foram observados em ambos os casos. Desmineralização e infiltração de restaurações evoluíram para erosão e uma lesão endodôntico (caso 1), e mobilidade com conseqüente perda de dentes (caso 2). Problemas com sangramento gengival, cárie e mobilidade dentária são relacionados diretamente a uma diminuição na área para absorção e/ou o comportamento alimentar do indivíduo após cirurgia bariátrica.
RESUMEN
BACKGROUND: This study examined the effect of weight loss on energy intake, vitamin C, E, beta-carotene (diet/blood), reduced glutathione (GSH), C-reactive protein (CRP), thiobarbituric acid reactive substances (TBARS), catalase, and myeloperoxidase, in patients with Roux-en-Y bypass gastroplasty. METHODS: Prospective clinical study with control (C) and bariatric (B) groups (n = 20 each). Age was 38.8 +/- 11.1 (C) and 37.8 +/- 11.2 years (B), and body mass indices (BMI) were 22.4 +/- 2.4 and 48.1 +/- 8.7 kg/m(2), respectively. Group C was assessed on a single occasion and B at three time points (basal period and 3 and 6 months after gastroplasty). RESULTS: BMI was decreased at three (38.3 +/- 1.7, P = 0.018) and 6 months after surgery (34.9 +/- 1.7, P < 0.001). Mean weight loss was 20.53 +/- 1.1 after three and 27.96 +/- 1.3 kg after 6 months. Serum vitamin C and beta-carotene (P < 0.01 and P < 0.001, respectively) were increased at 6 months compared to basal. Basal serum vitamin C (P = 0.001) and beta-carotene (P < 0.001) were lower compared to controls. Serum vitamin E corrected for cholesterol and triglycerides was higher in group B at three (P = 0.01) and 6 months (P = 0.001) and lower at basal (P < 0.001) compared to controls. GSH was higher in controls (P < 0.001) compared to basal. Catalase (P = 0.01) and TBARS (P < 0.001) were higher in group B at 6 months. TBARS were higher (P < 0.001) at basal compared to controls. Myeloperoxidase and CRP decreased in group B after three (P = 0.028, P = 0.010) and 6 months (P < 0.001, P = 0.001), respectively. CONCLUSIONS: Roux-en-Y bypass gastroplasty led to decreased proinflammatory parameters together with increased nutritional antioxidants, catalase, and TBARS, and decreased GSH 6 months after surgery.
