Pancreatic cancer is one of the most lethal malignancies, primarily due to late-stage diagnosis and limited therapeutic options. Cancer stem cells (CSCs) contribute to tumor heterogeneity, therapy resistance, and recurrence through activation of developmental pathways such as Hedgehog, Wnt, Notch, JAK-STAT, and Hippo. Identifying CSCs is therefore essential for understanding pancreatic ductal adenocarcinoma (PDAC) pathogenesis and advancing targeted therapies. This study compares the expression of key CSC-associated markers (CD44, CD117, OCT3/4, and c-Myc) in PDAC, fetal, and adult pancreas to elucidate CSC dynamics. Immunohistochemistry for CSC markers (CD44, CD117, OCT3/4, and c-Myc) was performed on PDAC tissues and control pancreatic samples (fetal pancreas 28–36 weeks and adult pancreas) to evaluate marker expression. Proliferative potential was assessed using CK7 and Ki-67 expression patterns. CD44 showed strong membranous and cytoplasmic expression in PDAC, moderate in fetal pancreas (epithelial/ductal regions), and minimal expression in adult tissue. CD117 was mainly restricted to stromal cells in PDAC, also present in fetal tissue but low in adults.c-Myc and Ki-67 were moderately expressed in PDAC, significantly higher than the control samples. CK7 demonstrated strong cytoplasmic staining in PDAC, moderate expression in adults, and weak expression in fetal samples. CD44 and c-Myc re-expression in PDAC supports their role as CSC-associated markers and potential drivers of tumor progression. CD117’s stromal localization suggests tumor–stroma interactions. These findings highlight developmental reactivation of CSC markers in PDAC, with implications for early detection and targeted therapy.

Arterial variations in upper limbs are often reported commonly. Superficial arterial variations accounting for 4.2% of all arterial variations are hazardous during any invasive procedures of the upper limb, from routine intravenous injections to surgeries. Arterial variations are usually associated with inverted or absent palmaris longus. Palmaris profundus, a rare anomalous variation of palmaris longus has been reported in carpal tunnel syndrome as its tendon was associated with median nerve in the carpal tunnel. The authors reported a unique variation in the upper limb arterial pattern—the presence of bilateral superficial brachioulnar artery associated with unilateral palmaris profundus muscle and an abnormal radicle of musculocutaneous nerve to the median nerve in the left side.

Severe alcoholic hepatitis has very high short term mortality and corticosteroids have been the mainstay of treatment for decades. Patients with Lille score >0.45 are considered non-responders to steroids and have poor outcome. Recently Orthotopic Liver Transplantation (OLT) is being increasingly used as rescue treatment for these patients, without waiting for 6 months of abstinence. Liver transplant is the only rescue treatment which can potentially provide long term benefit for patients who are steroid non-responders. However, with scarcity of organs being a concern, all patients of severe alcoholic hepatitis cannot be chosen for transplantation in an arbitrary way. There is a need for development of predictive tools and objective protocols to select patients who can justify the use of precious liver grafts. With a stringent criteria for selection of patients receiving the graft, liver transplantation in severe alcoholic hepatitis can become a viable rescue therapeutic option conferring significant survival advantage of both short- and long-term basis. The optimal criteria for selection will also prevent misuse of the liver donor pool as well as to prevent mortality in salvageable patients. Further research needs to be done to identify subset of patients which are at low risk of recidivism and also cannot be managed with pharmacotherapy alone. We reviewed the current knowledge on role of OLT in patient with acute severe alcoholic hepatitis in the present review.

Midgut malrotation and incomplete rotation are common causes of neonatal intestinal obstruction. At end of 10 week of intrauterine life, cecum will be placed in subhepatic region temporarily and descends to right lower quadrant by eleventh week. Arrest of cecum in subhepatic region or undescended cecum is a rare congenital anomaly of mid gut. Usually, it remains asymptomatic and is diagnosed incidentally. If any pathology occurs in anomalous part, like appendicitis then the diagnosis and treatment will be challenging in all age groups. Variation in blood supply have also been reported with anomalies leading to iatrogenic injuries during colonoscopy and surgeries. Lack of knowledge of these rare variations may lead to delayed diagnosis of appendicitis leading to perforation and surgical emergencies. In the present case, we describe an undescended cecum and its associated variation in branching pattern of superior mesenteric artery.
