Hemosuccus pancreaticus (HP) is a rare cause of upper gastrointestinal bleeding caused by bleeding from the ampulla of Vater into the duodenum. HP most commonly results from a rupture of pseudoaneurysms secondary to chronic pancreatitis. The low incidence of HP and the wide spectrum of its clinical presentation poses diagnostic challenges. We present a case of a 39-year-old male with acute-on-chronic pancreatitis resulting in HP and obstructive jaundice due to pancreatic pseudocyst with secondary hematoma. This case highlights the rare occurrence of hypovolemic shock due to massive hemorrhage in HP and the successful management with prompt cardiovascular support and angiographic coil embolization of a bleeding pancreatic pseudoaneurysm.

Background: The association of serum prolactin (PRL) with diabetes is still uncertain, with a paucity of data in the south Indian population. This study aims to compare the serum PRL levels between type 2 diabetes mellitus (T2DM) patients and normoglycaemic volunteers and correlate the serum PRL level with fasting plasma glucose (FPG), postprandial plasma glucose (PPG), glycated haemoglobin (HbA1c) levels, and the lipid profile in the study population. Methods: This was a comparative cross-sectional study among 112 T2DM participants and 112 healthy volunteers in a tertiary care centre in India. All participants were tested for FPG, PPG, HbA1c, fasting serum lipid profile, and serum PRL, which were compared between T2DM patients and healthy volunteers. Results: The serum PRL in T2DM patients was significantly lower compared to healthy volunteers (8.67 ± 4.37 vs. 13.76 ± 6.55 ng/ml, P < 0.001). FPG, PPG, and HbA1c correlated inversely with serum PRL in our study population. On multivariable logistic regression adjusted for age and sex, a higher serum PRL level within the physiological range was protective for T2DM (adjusted odds ratio: 0.83, 95% CI: 0.77-0.90, P < 0.001). Serum PRL levels were inversely correlated with serum total cholesterol, low-density lipoprotein cholesterol, and triglycerides, but not with high-density lipoprotein cholesterol. Conclusions: A high serum PRL within the physiological range was inversely associated with the prevalence of T2DM in the south Indian population. Serum PRL also correlated inversely with glycaemic and blood lipid parameters. Larger longitudinal studies are required to further validate the association of serum PRL with various components of metabolic syndrome in the south Indian population.
