Management of mucous membrane pemphigoid with dapsone plus weekly steroid injections in a young patient: a case report / Tratamento de penfigóide membranoso mucoso com dapsona e injeções semanais de esteróide em um paciente jovem: relato de caso

Purpose: Mucous Membrane Pemphigoid (MMP) is an autoimmune subepithelial blistering disorder usually affecting older individuals. This paper describes the pharmacological management of MMP in a young patient. Case description: A 23 year-old woman showed erythematous ulcerative gingiva in the maxillary palatal region and around the retromolar region. A perilesional excisional biopsy was done, and the histologic and immunohistochemical analysis confirmed the clinical diagnosis of MMP as the cause of desquamative gingivitis in this patient. The patient was treated with topical steroids plus daily Dapsone 100 mg and weekly steroid injections (40 mg). The lesions began to resolve after 12 weeks of therapy. Conclusion: This case of MMP in a young female patient was effectively managed with a combination therapy of topical steroids, Dapsone and steroid injections.

Objetivo: O penfigóide membranoso mucoso (PMM) é uma desordem autoimume subeptelial bolhosa que geralmente afeta indivíduos mais velhos. Este relato de caso descreve a abordagem farmacológica do PMM em uma paciente jovem. Descrição do caso: Uma paciente do sexo feminino, com 23 anos de idade, apresentava a gengiva eritematosa e ulcerada na região palatina e na região retromolar. A biópsia excisional total foi realizada e as análises histológica e de imuno-histoquímica confirmaram o diagnóstico clínico de PMM como causa da gengivite descamativa nesta paciente. A paciente foi tratada com esteróides tópicos, Dapsona 100 mg diariamente e injeções de esteróides mensais (40 mg). A resolução das lesões se iniciou após 12 semanas de terapia medicamentosa. Conclusão: Este caso de PMM em uma paciente jovem foi efetivamente tratado com uma terapia combinada de esteróides tópicos, Dapsona e injeções de esteróides.

Stromal changes in apparently normal mucosa of smokers and pan chewers: a multi-parametric approach

Aim: To compare and contrast the various changes in the connective tissue among patients with the habits of smoking, pan chewing and controls by using fluorescence spectroscopy, histopathology and transmission electron microscopy. Method: Thirty subjects were categorized into three groups: pan chewers, smokers and controls without any oral lesions. Fluorescence spectroscopy was carried out using FLUOROMAX-2. Excitation spectroscopy was performed at 280 and 320nm respectively and Emission spectroscopy was performed at 340 and 390nm excitation. Subsequently, histopathological evaluation and transmission electron microscopy was done for biopsies taken from test groups and controls. Results: The mean, standard deviation and test of significance of mean values between different groups for intensity-380nm, intensity–420nm and intensity – 460nm at 320 nm excitations, showed that the Mean values in group I and group II were significantly higher than the mean value in group III with a p-value of less than 0.001. Considering the histopathological parameters, the pattern of the sub-epithelial connective tissue, the presence of chronic inflammatory cells and lysis of connective tissue was significant. The ultrastructural analysis revealed the presence of epithelioid, spindle or elongated and stellate shaped fibroblasts in the connective tissue. Conclusion: In this pilot study, we could find variations in emission characteristics of various amino acids which correlated with histopathology and electron microscopy. Our study suggests that there are connective tissue changes in oral mucosa among smokers and pan chewers, though it is apparently normal in clinical presentation. These initial connective tissue changes could determine the progression of altered mucosa to a pre-cancer or cancer, which is further related to other complex interactions. Elaborate studies are required to evaluate the significance of our hypothesis.

Oral signs and salivary parameters as indicators of possible osteoporosis and osteopenia in postmenopausal women: a study of 45 subjects

Aim: To correlate the oral signs, salivary calcium, phosphorus, alkaline phosphatase levels and dental radiographic findings in postmenopausal osteoporotic, osteopenic and non-osteoporotic women. Materials and Methods: Forty-five subjects were selected based on bone mineral density (BMD) analyses and were assigned to 3 groups (n=15): Group 1 - established osteoporotic women; Group II - established osteopenic women; Group III (control) - non-osteoporotic women. Complete oral and radiographic examination, saliva collection and analysis of calcium, phosphorus and alkaline phosphatase were performed. Results: The results were tabulated and analyzed for statistical significance using the Mann-Whitney U-test. There was statistically significant difference (p<0.05) in salivary calcium, phosphorus and alkaline phosphatase levels when osteoporotic and osteopenic women were compared to the controls. Conclusion: Salivary parameters can be used as indicators to aid in the diagnosis of osteoporosis and osteopenia in postmenopausal women.
