Retrospective Analysis of Acute Kidney Injury in COVID-19 Infection: A Single-Center Study From Kerala.

Introduction The COVID-19 pandemic, caused by SARS-CoV-2, has resulted in significant morbidity and mortality worldwide. While primarily a respiratory illness, COVID-19 can lead to multi-organ involvement, including acute kidney injury (AKI). This study aimed to retrospectively analyze the incidence, risk factors, and outcomes of AKI in COVID-19 patients.

Long-term complications after extrahepatic cyst excision for type IV-A choledochal cysts.

Forty-five adults with type IV-A choledochal cysts (CDC) who underwent extrahepatic cyst excision from January 2013 to December 2021 were followed up for a median interval of 25 months (range, 2 to 10 years) to observe the long-term complications in the remaining intrahepatic cyst. Late complications in varying combinations were seen in 10 patients, which included cholangitis and/or intrahepatic stones in 9 patients, intrahepatic bile duct stenosis with stones in 2 patients, anastomotic stricture in 6 patients, and left lobar atrophy with intrahepatic stones in 3 patients. Out of 6 patients who required re-do hepaticojejunostomy (HJ), three patients had left lobe atrophy with patent HJ anastomosis and a recurrent attack of cholangitis on follow-up at 3, 8, and 10 years.

Giant Adrenal Pseudocysts: An Enigma for Surgeons.

Adrenal pseudocysts are cystic lesions arising within the adrenal gland enclosed by a fibrous connective tissue wall that lacks lining cells. They can attain a huge size and pose a diagnostic challenge with a broad range of differentials including benign and malignant neoplasms. There are only a few small case series and case reports describing these lesions.

Analysis of outcomes of biliary reconstruction after post-cholecystectomy bile duct injuries.

Background: Post-cholecystectomy bile duct injury (BDI) is a serious complication that often requires surgical repair. This study aimed to analyze the outcomes of surgery performed for BDI and to determine the factors associated with post-surgical complications.

Methods: A retrospective analysis was conducted using a prospectively maintained database of 105 patients who underwent surgical repair for post-cholecystectomy BDI between March 2013 and March 2020.

Pain in Chronic Pancreatitis During the COVID-19 Lockdown: Has It Given Us a New Dimension for Treatment?

Background Prolonged lockdown in our country provided us with a unique opportunity to study the interplay of psychosocial impact on pain in surgically treated patients of chronic pancreatitis. Methods Forty-one patients who underwent surgery for chronic pancreatitis in the last 24 months were followed up, of which 27 were enrolled. The data were collected telephonically.

An Unusual Postoperative Complication of Retrosternal Gastric Pull-Up for Corrosive Esophageal Stricture.

Retrosternal gastric pull-up with side-to-side esophagogastric anastomosis is the surgery done for corrosive esophageal stricture unresponsive to endoscopic dilatation. This surgery is considered safe in terms of morbidity. Complications due to leak from distal esophageal staple line as a result of partially patent bypassed esophageal lumen have never been reported with this surgery.

Proximal Splenorenal Shunt Surgery for Bleeding Gastric Varices in Non-Cirrhotic Portal Hypertension.

Background The optimal management of gastric variceal bleeding in patients with non-cirrhotic portal hypertension (NCPH) is debatable due to the lack of data from large randomized controlled trials. Here we present our experience on proximal splenorenal shunt (PSRS) surgery in NCPH patients with bleeding gastric varices. Methods Over a five-year period, a total of 25 PSRS surgeries were performed and data was collected prospectively.

Post Traumatic Lemmel's Syndrome: A Rarest of Rare Cause of Obstructive Jaundice.

Obstructive jaundice caused by periampullary duodenal diverticulum in absence of choledocholithiasis or tumor is known as Lemmel syndrome. This is a rare cause of obstructive jaundice. We report here a patient of blunt trauma abdomen who underwent emergency laparotomy whose sequelae was a controlled external biliary fistula which healed and led to obstructive jaundice.

Short-Term Hypoxia Dampens Inflammation in vivo via Enhanced Adenosine Release and Adenosine 2B Receptor Stimulation.

Hypoxia and inflammation are closely intertwined phenomena. Critically ill patients often suffer from systemic inflammatory conditions and concurrently experience short-lived hypoxia. We evaluated the effects of short-term hypoxia on systemic inflammation, and show that it potently attenuates pro-inflammatory cytokine responses during murine endotoxemia.

Plasma levels of danger-associated molecular patterns are associated with immune suppression in trauma patients.

Purpose: Danger-associated molecular patterns (DAMPs) released of trauma could contribute to an immune suppressed state that renders patients vulnerable towards nosocomial infections. We investigated DAMP release in trauma patients, starting in the prehospital phase, and assessed its relationship with immune suppression and nosocomial infections.

Methods: Blood was obtained from 166 adult trauma patients at the trauma scene, emergency room (ER), and serially afterwards.

Short-term hyperoxia does not exert immunologic effects during experimental murine and human endotoxemia.

Oxygen therapy to maintain tissue oxygenation is one of the cornerstones of critical care. Therefore, hyperoxia is often encountered in critically ill patients. Epidemiologic studies have demonstrated that hyperoxia may affect outcome, although mechanisms are unclear.

Effect of the antihepcidin Spiegelmer lexaptepid on inflammation-induced decrease in serum iron in humans.

Increased hepcidin production is key to the development of anemia of inflammation. We investigated whether lexaptepid, an antihepcidin l-oligoribonucleotide, prevents the decrease in serum iron during experimental human endotoxemia. This randomized, double-blind, placebo-controlled trial was carried out in 24 healthy males.
