Impact of Pneumoperitoneum on the Development of Acute Kidney Injury: Comparison Between Normal and Diabetic Rats.

Background: Minimally invasive surgery is considered the gold-standard approach for many surgical procedures. However, it requires CO2 insufflation and elevated intra-abdominal pressure (IAP), which may result in adverse pulmonary, cardiovascular, gastrointestinal, and renal changes. The kidneys are highly sensitive to pressure changes, where risk factors such as severe infection, dehydration, older age, and chronic kidney disease may aggravate the likelihood for the development of acute kidney injury (AKI).

Increased Intra-abdominal Pressure Induces Acute Kidney Injury in an Experimental Model of Congestive Heart Failure.

Background: Congestive heart failure (CHF) entails a complex interaction between the heart and the kidney that represents a clinical entity called cardiorenal syndrome (CRS). One of the mechanisms underlying CRS includes increased intra-abdominal pressure (IAP). We examined the effect of elevated IAP on kidney function in rats with low- and high-output CHF.

[SHOULD PATIENTS WITH PRIMARY HYPERPARATHYROIDISM AND NEGATIVE IMAGING STUDIES BE REFERRED TO SURGERY?].

Introduction: Parathyroidectomy is the only curative treatment for primary hyperparathyroidism (PHPT). In cases where imaging fails to demonstrate an adenoma, a bilateral neck exploration (BNE) is performed. Negative imaging is thought to predict surgical failure, and patients with negative imaging are often not referred for surgery.

Primary Ewing Sarcoma/Primitive Neuroectodermal Tumor of the Stomach.

Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) is a tumor of small round cells arising in skeletal tissues. These tumors rarely arise in the stomach. We present a 31-year-old healthy female patient who was admitted to our surgical ward due to upper gastrointestinal hemorrhage.

Negative Fine-Needle Aspiration in Patients with Goiter: Should We Doubt It?

Background: Epidemiologic studies demonstrated higher incidence of thyroid cancer in patients with multinodular goiters compared to the general population. The aim of this study was to evaluate the risk of finding significant thyroid cancer in patients undergoing thyroidectomy for presumed benign disease.

Methods: The records of 273 patients operated for indications other than cancer or indeterminate cytology were reviewed and analyzed.
