Primary versus secondary cutaneous endometriosis: Literature review and case study.

Cutaneous endometriosis, characterized by the presence of endometrium or endometrial-like tissue outside of the uterine cavity, is an uncommon and chronic disease. Depending on a patient's history, cutaneous endometriosis is classified as either primary cutaneous endometriosis (PCE) or secondary cutaneous endometriosis (SCE). We report a case of SCE presenting with the classic triad of previous caesarean section, subcutaneous nodules at the site of the scar, and pain associated with menstruation.

Chondroid syringoma of the lower back simulating lipoma: A case report.

Background: Chondroid syringoma (CS) is a rare tumor of the apocrine or eccrine glands. CS of the lower back is rare, and its clinical manifestations are similar to those of lipoma, which is a common misdiagnosis for this disease.

Case Summary: A 39-year-old woman presented with a 2-year history of an asymptomatic subcutaneous mass on the lower back.

Rat experimental model of continuous regional arterial infusion of protease inhibitor and its effects on severe acute pancreatitis.

Objectives: The rat experimental model of continuous regional arterial infusion of protease inhibitor (CRAI) on acute pancreatitis has yet to be established. Therefore, the aims of this study were (1) to establish the rat experimental model of CRAI and (2) to evaluate the effects of nafamostat on rat severe acute pancreatitis via different routes of administration.

Methods: The rat internal jugular vein or the celiac artery was infused with nafamostat, and the concentration of nafamostat in the lung and pancreas was measured.

Do peritoneal macrophages play an essential role in the progression of acute pancreatitis in rats?

Introduction: Macrophages are considered to play an essential role in the events leading to systemic inflammatory response. Some are known to reside in the peritoneal cavity but there are no reports defining the participation of peritoneal macrophages (PMs) in the progression of acute pancreatitis.

Aim: To clarify the role of PMs in the progression of acute pancreatitis.

Peritoneal inflammatory cells in acute pancreatitis: Relationship of infiltration dynamics and cytokine production with severity of illness.

Background: The purpose of this study was to clarify the still poorly understood dynamics of peritoneal inflammatory cells (PICs) in acute pancreatitis.

Methods: Acute pancreatitis of 3 different degrees of severity was induced in male Wistar rats. Peritoneal lavage was performed at 1, 6, 12, and 24 hours after the induction, and the fluids collected were analyzed for the number and subpopulation of PICs.
