Effects of Secondary Hyperparathyroidism Treatment on Improvement in Anemia: Results from the MBD-5D Study.

Objectives: Anemia is an important prognostic factor in hemodialysis patients. It has been reported that parathyroidectomy ameliorates anemia and reduces the requirement of postoperative erythropoiesis-stimulating agents. The objective of this study was to assess the effect of cinacalcet, which is considered as a pharmacological parathyroidectomy, on anemia in hemodialysis patients.

A rare case of Cushing's syndrome due to bilateral adrenocortical adenomas.

We report a rare case of Cushing's syndrome caused by bilateral cortisol-secreting adenomas in a 63-year-old man. Our preoperative diagnosis was based on endocrinological results and imaging findings. Laparoscopic adrenalectomy has become a standard technique for adrenal tumors; however, bilateral adrenalectomy results in postoperative adrenal insufficiency, necessitating lifelong steroid replacement.

Variant of lymphocytic infundibulo-neurohypophysitis presenting with unique clinical and radiological features.

Lymphocytic hypophysitis (LYH) is a chronic inflammation that primarily affects the pituitary gland. This disorder has recently been classified into lymphocytic adenohypophysitis (LAH), lymphocytic infundibulo-neurohypophysitis (LINH), and lymphocytic infundibulo-panhypophysitis (LIPH) according to the affected area. We report a case of LINH in a 68-year-old woman who presented with diabetes insipidus (DI).

[Usefulness of power Doppler ultrasonography for the diagnosis of autoinfarction of parathyroid gland in secondary hyperparathyroidism].

Spontaneous remission due to parathyroid infarction of secondary hyperparathyroidism is rare compared with that of primary hyperparathyroidism, probably because several glands are enlarged in secondary hyperparathyroidism. Lately, neck ultrasound examination has become a more beneficial and specific method for the diagnosis of enlarged parathyroid glands in contrast to classic diagnostic techniques such as computed tomography (CT), magnetic resonance imaging (MRI) and scintigraphy. However, the diagnosis of parathyroid infarction reported in previous studies was often based on CT, MRI and scintigraphy findings and there are few studies that reported such diagnosis by urgent power Doppler ultrasonography of the neck.

Nasopharyngeal penicillin-resistant Streptococcus pneumoniae strains among young children in Japan.

Objective: A rapid increase of penicillin resistance in Streptococcus pneumoniae has recently been reported in most areas of the world. Penicillin-resistant S. pneumoniae and other resistant bacteria are the principal causes of recurrent acute otitis media (AOM).
