Background: Gestational diabetes insipidus (DI) is a very rare complication of pregnancy. We present a case of gestational DI combining two different types of DI. .

Background: Cases of subacute thyroiditis (SAT) after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination have been reported. A human leukocyte antigen (HLA) allele, HLA-B*35, appears to be involved in the pathogenesis of SAT.

Case Presentation: We conducted HLA typing of one patient with SAT and another with both SAT and Graves' disease (GD), which developed after SARS-CoV-2 vaccination.

We encountered a 70-year-old Japanese woman with neurofibromatosis type 1 (NF1) who had a history of pheochromocytoma and concurrently developed adenomatous goiter, primary hyperparathyroidism, and acromegaly. The patient had a somatotroph adenoma of the adenohypophysis that predisposed her to multinodular goiter. Three parathyroid tumors were detected by cervical ultrasonography and cervicothoracic computed tomography.

Aims: To examine the effects of strict glycemic control on the birthweight of infants born to Japanese patients with early- or mid-to-late-detected gestational diabetes mellitus (ed- or md-GDM).

Methods: We retrospectively examined the characteristics of 101 patients with GDM who underwent guideline-based glycemic control. A 75-g oral glucose tolerance test was conducted to diagnose GDM at gestational weeks 11-15 (ed-GDM subgroup) and 24-28 (md-GDM subgroup).

Background: It is important to distinguish benign thyroid nodules from malignant thyroid nodules. Hence, this study aimed to determine the characteristics of patients with thyroid cancer using thyroid ultrasonography.

Methods: We retrospectively examined the ultrasonographic findings of 327 patients with 457 thyroid nodules (age: 59.

Background: Primary aldosteronism (PA) plus subclinical Cushing's syndrome (SCS), PASCS, has occasionally been reported. We aimed to clinically characterize patients with PASCS who are poorly profiled.

Methods: A population-based, retrospective, single-center, observational study was conducted in 71 patients (age, 58.

Aims/introduction: The aim of the present study was to examine the associations of pregestational body mass index (BMI) and gestational weight change with birthweight for gestational age in Japanese mothers with gestational diabetes mellitus (GDM).

Materials And Methods: We retrospectively examined the clinical and laboratory characteristics of 101 mothers with GDM (pregestational BMI 24.7 ± 5.

Background: Methimazole (MMI) is usually used at an initial dose of 30 mg/day for severe Graves' disease (GD) hyperthyroidism, but adverse effects are more frequent at this dose than at MMI 15 mg/day.

Objectives: We designed a regimen to address the lack of a primary therapeutic effect of the MMI 15 mg/day by combining it with inorganic iodine at 38.2 mg/day.

Objective: To describe an exceedingly rare case of tumor-induced osteomalacia (TIO) caused by a benign phosphaturic mesenchymal tumor that recurred after two surgical resections at two different medical institutions.

Methods: A 69-year-old man complained of a 3-year history of persistent whole body pain and presented with hypophosphatemia, elevated serum levels of bone-specific alkaline phosphatase and fibroblast growth factor-23 (FGF-23), and multiple fractures. The patient was suspected of having TIO.

Background: Thyroid ultrasonography (US) is the most sensitive method for detecting thyroid nodules, and US-guided aspiration biopsy is the most accurate diagnostic procedure for thyroid nodules. We performed this retrospective study to establish the prevalence of thyroid nodules in Graves' disease and patients with Hashimoto's thyroiditis at the time of their initial visit.

Methods: We performed thyroid US as routine screening in 1652 patients with Graves' disease and 2036 Hashimoto's thyroiditis and performed US-guided fine-needle aspiration biopsy when the diameter of a nodule >1 cm or a nodule was suspected of being malignant.

Diabetes mellitus is considered as a risk factor for fractures, and there are some reports showing that metabolic effects of poor glycemic control resulted in lower bone turnover. Previous studies have revealed that this reduction of bone turnover increases bone fragility, independently of bone mineral density, so that the mechanisms of diabetic osteopahty seem to be more closely related to bone quality than bone quantity. The mechanisms of the preventive effect on fractures by vitamin K treatment should be related to amelioration of bone quality via increasing amounts of carboxylated osteocalcin.

The nucleocytoplasmic shuttling protein, A+U-rich element binding factor 1 (AUF1), is one of the RNA-binding proteins that specifically bind adenylate-uridylate rich elements (AREs) in mRNA 3'-untranslated regions (UTRs), and acts as a regulator of ARE-mediated mRNA degradation in the cytoplasm. We previously reported that in the female rat uterus, the levels of specific AUF1 isoform mRNAs (p40/p45) were increased by 17 beta-estradiol (E2) treatment. Therefore, we examined the role of AUF1 in the regulation of E2-mediated mRNA turnover in the rat uterus.

Our previous results in mouse osteoclasts suggested that calcitonin (CT) alters CT receptor (CTR) mRNA stability. The CTR mRNA transcript contains several adenylate/uridylate (AU)-rich destabilizing elements in the 3' untranslated region (3'UTR). When the 3'UTR of mouse CTR mRNA was labeled by [alpha-(32)P]-uridine 5-triphosphate, interactions were observed between the transcript and several cell extracts, including those from the osteoclast progenitor monocyte/macrophage cell line, RAW 264.

Glucocorticoid-induced osteoporosis is one of the major complications of long-term exposure to supraphysiological doses of glucocorticoid. It has been recognized that bone loss is rapid, particularly in the first 6 months of the therapy. The skeletal effects are both dose and duration dependent; daily glucocorticoid therapy at doses of 7.

Primary mucoepidermoid carcinoma (MEC) of the thyroid is very rare, and its origin has not been fully determined. We report a case of MEC, the origin of which was demonstrated by thyroid specific genes expressed in a metastatic lymph node. A 52-year-old male presented with chest pain, weight loss and diffuse goitre.
