Transfusion-associated graft-versus-host disease (TA-GVHD) and graft-versus-host disease (GVHD): Pathophysiology and management (contrasted and compared).

Transfusion of blood products is a common lifesaving medical procedure in clinical practice. However, it poses the risk of potential adverse reactions for the recipient. Transfusion-associated graft-versus-host-disease (TA-GVHD) is a rare adverse event, fatal in >90% of cases.

Cell adhesion molecules' altered profile in benign and malignant salivary gland tumors. The paradigm of beta4-integrin, desmoglein-2, ICAM-1 and CD44s.

Background: Alterations in intercellular and cell-extracellular matrix connections contribute to tumour development. This study investigates the expression of specific cell adhesion molecules (CAMs) in salivary gland tumors (SGTs).

Methods: Formalin-fixed, paraffin- embedded tissue specimens of different types of 34 benign and 31 malignant SGTs and normal salivary glands were studied using Envision/HRP immunohistochemical technique for Desmoglein-2 (Dsg-2), beta4-integrin, CD44s and ICAM-1.

Diagnosis and surgical management of spontaneous hepatic rupture associated with HELLP syndrome.

Spontaneous hepatic rupture with hemoperitoneum is an uncommon but devastating complication of hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome. Although the syndrome has been considered a variant of preeclampsia/eclampsia, its pathogenesis is not completely understood. Hepatic rupture increases the perinatal and maternal morbidity and mortality.
