Hyperthyroid heart disease in pregnancy: Retrospective analysis of a case series and review of the literature

BACKGROUND Hyperthyroidism in pregnancy may pose a great threat to maternal and fetal health.The risk of hyperthyroid heart disease(HHD),even heart failure,is significantly elevated in pregnant women.AIM To investigate the clinical characteristics,prognosis,and therapy of HHD in pregnant women.METHODS We searched the patient registry data at West China Second University Hospital of Sichuan University in Chengdu,China,following the approval by the Ethics Committee.We retrospectively analyzed the clinical characteristics of pregnant women diagnosed with HHD.The medical records of women with HHD during pregnancy from January 2012 to December 2017 were obtained from the electronic medical records system.All the included patients were followed in outpatient clinics and by telephone interviews until October 2018.RESULTS A total of 155 patients were diagnosed with thyrotoxicosis,of whom six were diagnosed with HHD.Three of them had regular antenatal care.Two patients were complicated with acute heart failure attacks,and one of them had a stillbirth.Both of these patients had a long history of Graves’disease with poor treatment compliance.Treatments of precipitating factors such as the control of infection could relieve the symptoms and prolong gestation for a better prognosis.Hyperthyroid heart failure could be controlled with aggressive diuretics and management of the coexisting complications.Intense monitoring and timely anti-heart failure treatment were crucial in patients with severe cardiac damage.Our findings indicated the importance of regular antenatal care and treatment adherence in patients with hyperthyroidism.CONCLUSION The timely and accurate diagnosis of HHD and the implementation of effective management are important for a better prognosis in pregnant women with HHD.Improvement in patients’awareness of thyrotoxicosis is needed.

Primary mesonephric adenocarcinoma of the fallopian tube:A case report

BACKGROUND Mesonephric adenocarcinoma(MNAC)is an extremely rare malignancy in the female genital tract.Only a few cases have been reported in the literature,and most of them occurred in the cervix,with extremely rare cases in the uterine body and ovary.MNAC has never been reported to arise in the fallopian tube.CASE SUMMARY A 45-year-old woman was referred to our institution with a history of abdominal pain.Ultrasound revealed a cystic and solid mass in left adnexal region.The patient underwent complete staging surgery when intraoperative pathological examination demonstrated that the mass was malignant.The final histological and immunohistochemical results confirmed the diagnosis of MNAC originating from the fallopian tube.Then she received four cycles of combination chemotherapy with carboplatin plus paclitaxel.The tumor recurred with hepatic metastases 4 mo after initial surgery,and second resection of the tumors in the liver plus partial hepatectomy was performed.She was supplemented with five courses of a new combination chemotherapy with gemcitabine plus carboplatin,and there was no evidence of recurrence within the 22-mo follow-up period after the second surgery.CONCLUSION MNAC originating from the fallopian tube is an extremely rare and high malignancy with a poor prognosis.It can be very aggressive,even at early stage.Little is known about the clinical characteristics,pathological diagnosis,prognosis,and optimal management strategy of MNAC originating from the fallopian tube.Herein we report the first case of primary MNAC deriving from the fallopian tube.
