Segmental Absence of Intestinal Musculature: An Enticing Predicament.

Segmental absence of intestinal musculature (SAIM) was first identified as a cause of intestinal perforation and remains difficult to diagnose clinically. Diagnosing SAIM preoperatively can be difficult; however, detection during the surgical procedure may be feasible if gross observations reveal bowel alterations such as a thinned-out wall, signs of gangrenous changes, or adjacent bowel dilatation. A final diagnosis can be made with the help of histopathology, making it a gold standard.

Expression of PD-L1 in Lung Carcinoma and Its Correlation with Histopathological Grade, Stage, and Survival of Patients.

 PD-L1, a 40 kDa type 1 transmembrane protein, suppresses the adaptive arm of the immune system. The interaction of PD-1 with the ligand PD-L1 inhibits cytokine production and plays a role in the progression of lung cancer. The present study was performed to observe the expression of PD-L1 in lung carcinoma patients and its correlation with histopathological grade, stage, and survival of patients.
