Initial Presentation of Ovarian Carcinosarcoma With Non-islet Cell Tumor Hypoglycemia: A Case Report.

Ovarian cancer, although not among the most commonly diagnosed cancers, remains a significant cause of cancer-related mortality in females. Several paraneoplastic syndromes have been associated, and this case study represents a rare manifestation of ovarian cancer, presenting as non-islet cell tumor hypoglycemia (NICTH), characterized by the excessive production of insulin-like growth factor-II (IGF-II) by tumor cells. We report a 55-year-old woman who presented to our hospital with abdominal distension and severe refractory hypoglycemia.

A Case of Metformin-Associated Lactic Acidosis Complicated by Acute Liver Failure, Acute Renal Failure, and Shock.

Metformin is an oral antihyperglycemic agent used for type 2 diabetes mellitus (T2DM) management and is considered to be the first-line treatment for diabetic patients. It works by improving insulin sensitivity, reducing intestinal absorption, and decreasing glucose production in the liver, leading to decreased blood glucose levels. It is generally considered a safe drug; however, it is associated with an uncommon but serious side effect known as metformin-associated lactic acidosis (MALA), a potentially life-threatening condition.

Atypical Pulmonary Metastasis of Prostate Adenocarcinoma: A Rare Phenomenon.

Unlabelled: Prostate cancer can metastasise to the lung. Most common presentations described in the literature are solitary pulmonary nodules, lymphangitic spread and, rarely, pleural effusion. We describe a case of prostate adenocarcinoma with diffuse bilateral reticulonodular and lymphangitic pulmonary metastasis, and malignant pleural effusion while being on androgen deprivation therapy.

Surviving the Storm: Cardiac Tamponade and Effusive Constrictive Pericarditis Complicated by Pericardial Decompression Syndrome Induced by COVID-19 Infection in the Setting of Newly Diagnosed Acute Myeloid Leukemia (AML).

Coronavirus disease 2019 (COVID-19)-induced pericarditis and pericardial myocarditis are common entities; however, the development of pericardial effusion post-COVID-19 infection has only been reported in about 5% of cases. Rapid and acute progression to pericardial tamponade is uncommon, and progression to effusive constrictive pericarditis (ECP) and pericardial decompression syndrome (PDS) is an even rarer phenomenon. We describe these phenomena in this report to raise awareness and aid clinicians in the early diagnosis and management of these conditions.

Sex peptide receptor is not required for refractoriness to remating or induction of egg laying in Aedes aegypti.

Across diverse insect taxa, the behavior and physiology of females dramatically changes after mating-processes largely triggered by the transfer of seminal proteins from their mates. In the vinegar fly Drosophila melanogaster, the seminal protein sex peptide (SP) decreases the likelihood of female flies remating and causes additional behavioral and physiological changes that promote fertility including increasing egg production. Although SP is only found in the Drosophila genus, its receptor, sex peptide receptor (SPR), is the widely conserved myoinhibitory peptide (MIP) receptor.
