Electroconvulsive therapy for burning mouth syndrome.

OBJECTIVE: Burning mouth syndrome (BMS) is an orofacial pain disorder characterized by a chronic, idiopathic burning sensation of the oral mucosa that mostly affects middle-aged women. Although both psychological and neuropathological factors have been postulated to underlie BMS, the pathogenic mechanism of the condition remains controversial, as do the treatment strategies. METHOD: A single case was reported. RESULTS: Ms A, a 66-year-old woman with BMS type 1, which is characterized by daily burning pain associated with circadian variation, underwent electroconvulsive therapy (ECT). After the completion of 12 ECTs, the pain markedly diminished and the pronounced ECT effect persisted over the subsequent 24-week period of observation. CONCLUSION: To our knowledge, this is the first clinical report on the efficacy of ECT for treating pain associated with BMS. ECT can be considered to be an option for treating individuals with enduring and intractable intraoral burning pain.

Poor maternal care and high maternal body mass index in pregnancy as a risk factor for schizophrenia in offspring.

OBJECTIVE: We investigated whether antenatal factors in mothers would increase the risk of schizophrenia in the offspring, and also examined any relationship between these factors and histories of obstetric complications (OCs). METHOD: Using the Mother and Child Health Handbooks of 52 patients with schizophrenia and 284 healthy subjects, we evaluated the risk-increasing effects of the frequency of antenatal care visits and mothers' body mass index (BMI) at both early and late pregnancy. RESULTS: In logistic regression analysis, there was a significant association between the number of antenatal care visits and the risk of the disorder; an increase in a unit of visits corresponds to a reduction of the risk by 12%. We also found a 24% increase in the risk with a one-unit increase of BMI at the early pregnancy, and a 19% increase at the late pregnancy. These antenatal factors were found to contribute, in part, to an excess of OCs in individuals with schizophrenia. CONCLUSION: Poor maternal care during pregnancy and comparatively high maternal BMI especially at early pregnancy may cause a predisposition to schizophrenia in the offspring.
