Intravascular large B-cell lymphoma with respiratory failure diagnosed by random skin biopsy: A case report.

Intravascular large B-cell lymphoma (IVLBCL) typically involves nonspecific symptoms that complicate diagnosis. This report discusses the case of a 70-year-old man, who presented with dyspnea, fatigue, and weight loss that evolved into severe respiratory failure, diagnosed with IVLBCL via random skin biopsy. The initial improvement in respiratory symptoms was followed by coronavirus disease.

A Case of Septic Pulmonary Embolism Caused by Pyelonephritis With Klebsiella pneumoniae in a Patient With Poorly Controlled Type 2 Diabetes Mellitus.

Septic pulmonary embolism (SPE) is caused by the microbe that is responsible for any clinical condition that may include urinary tract infections as in this case. We report a case of pyelonephritis with that led to SPE in an 80-year-old woman with poorly controlled diabetes mellitus (DM). Computed tomography (CT) revealed multiple nodules in the peripheral area of the bilateral lung and a contrast defect in the right renal vein, which was suspected to be an embolism.

Recurrent hyperglycemic hyperosmolar state after re-administration of dose-reduced ceritinib, an anaplastic lymphoma kinase inhibitor.

Ceritinib is a second-generation anaplastic lymphoma kinase (ALK) inhibitor with clinical activity in crizotinib-resistant ALK-positive non-small cell lung cancer and in treatment-naïve ALK-positive disease. Hyperglycemia is a known adverse event, but the mechanism by which ceritinib causes hyperglycemia is unknown, and whether ceritinib causes hyperglycemic emergencies is unclear. Here, we report the case of a patient with a hyperglycemic hyperosmolar state (HHS) recurrence after the re-administration of dose-reduced ceritinib.

Clinical efficacy and pharmacokinetics of levothyroxine suppository in patients with hypothyroidism.

This study aimed to elucidate the clinical efficacy and pharmacokinetics of levothyroxine (LT4) suppository, thus, we examined the pharmacokinetics of thyroxine (T4) after the administration of the suppository in thyroidectomized rats and examined dose and the levels of free T4 (FT4) in patients with hypothyroidism receiving suppositories. Thyroidectomized rats were administered with LT4 solution and LT4 suppository (30 µg/kg), and plasma T4 concentrations were measured using LC/MS. The AUC0-168 of T4 after rectal administration of the LT4 suppository was 64% lower than these values after oral administration.
