Two dogs presented with vomiting and head pressing. In both dogs, a large vessel was revealed in computed tomography (CT) angiography, which was found to leave the portal vein (PV) cranial to the splenomesenteric confluence and enter the pre-hepatic caudal vena cava cranial to the right renal vein. The flow of portal blood to the liver was not identified. Based on CT angiography, the dogs were suspected to have congenital PV aplasia with portocaval shunting. Diagnostic imaging of potential malformations for PV continuation should be conducted before attempting shunt closure.

BACKGROUND: Early escharectomy has been shown to improve survival rates and treatment outcomes in major burn patients. However, its mechanism, especially in human immune systems, has not been fully elucidated. This observational study, focusing on cytokines, was conducted to assess changes in the levels of tumor necrosis factor alpha (TNF alpha) and interleukin-10 (IL-10) in major burn patients that underwent early tissue excision. METHODS: Seventeen ASA physical status II or III adults major burn patients, admitted to general surgery for burn wound care, were initially recruited. When early escharectomy was scheduled, a series of blood samples was obtained four times at 72 and 24 hours preop and at 24 and 72 hours postop. Changing levels of TNF alpha and IL-10 were measured by quantitative sandwich immnuoassay. RESULTS: Subjects suffered from 70% TBSA burns. Both cytokines demonstrated a significant tendency to increase in the blood during the study period. Although they temporarily decreased 24 hours after surgery, this effect did not last. CONCLUSIONS: Burn injury certainly increases cytokine response. Early escharectomy appears to decrease the pro and anti-inflammatory cytokines only temporarily. It did not seem to have any long term effect in the human immune system in major burn patients, probably due to the complex nature of the injury.

Pseudomyxoma peritonei is a rare clinical condition that causes the accumulation of mucinous ascites, which gradually results in the compression of intra-abdominal organs. Most published reports of pseudomyxoma peritonei concern the mass effect of the resulting ascites, which presents as abdominal pain or intestinal ileus in severe cases. However, few reports of renal complications of the disease have been published. Here, we present a case of oliguric acute kidney injury caused by external compression by pseudomyxoma peritonei. After decompression with external drainage, the patient's renal function rapidly improved.
