Type B Lactic Acidosis: A Very Rare but Fatal Complication of Gastrointestinal Solid Tumor.

Type B lactic acidosis, secondary to solid cancer, is very rare. It is mostly seen in patients with hematological malignancies. Although its exact pathogenesis is unknown, it is believed to be caused by overproduction and the inability of tumor cells to remove lactate.

Acute Acalculous Cholecystitis Due to COVID-19, an Unusual Presentation.

Although the Coronavirus Disease 2019 (COVID-19) infection mainly affects the lung, its gastrointestinal (GI) involvements are also well-known, especially hepatic involvement presenting as mild to moderate transaminitis. However, COVID-19 infection presenting with gall bladder involvement with acalculous cholecystitis is extremely rare in the medical literature. So far, only two cases have been reported, and herein, we are reporting the third case of a patient who developed COVID-19 presenting as an acute acalculous cholecystitis.

Intestinal angioedema caused by an acquired C1 esterase inhibitor deficiency associated with underlying splenic marginal zone lymphoma.

A 75-year-old woman presented with recurrent abdominal pain and vomiting for 1 year and was later found to have splenomegaly and pancytopenia. This case report depicts a clinical picture of intestinal angioedema, a challenging diagnosis, and an underlying rare syndrome of acquired C1 esterase inhibitor deficiency associated with splenic marginal zone lymphoma.

Atypical Presentation of Fatal Disease: Painless Aortic Dissection.

Aortic dissections (ADs) are uncommon but they are highly lethal. Due to atypical signs and symptoms, diagnosis of type B AD can be easily missed or delayed. Our patient presented to the emergency center with dizziness and fall for which he was evaluated and treated for hypertension.

Primary Pancreatic Large B-Cell Lymphoma Presenting as Acute Pancreatitis.

Primary pancreatic lymphoma (PPL) is an extremely rare form of extranodal malignant lymphoma. The most common histological subtype of PPL is diffuse large B-cell lymphoma (DLBCL). Clinical and imaging features of PPL may often overlap with pancreatic adenocarcinoma.

Pica/Pagophagia-Associated Hyponatremia: Patient Presenting With Seizure.

Pica is an unusual condition in which patients crave and chew substances with no nutritional value. Ice pica (pagophagia) is commonly seen in patient with iron deficiency. People chew ice cubes or add ice to their drinks to cool or refresh themselves, and they may not consider this as an abnormal behavior.

Relation between mean platelet volume and C-reactive protein.

Mean platelet volume (MPV) is a measure of platelet activation, and C-reactive protein (CRP) is an established marker of inflammation. Studies on the correlation between MPV and CRP have produced ambiguous results. We undertook a population study with the National Health and Nutrition Examination Survey (NHANES) data (2005-2010) to investigate the relationship between CRP and MPV.
