Hepatic Abscess Induced by Fish Bone Migration: Two Case Reports
Mateus, José Eduardo; Silva, Carlos; Beirão, Sofia; Pimentel, JorgeAlthough foreign body ingestion is a common occurrence, perforation and penetration of the gastrointestinal tract is unusual and the development of a hepatic abscess is even more rare. The authors describe two cases of fish bone perforation of the gastrointestinal tract with hepatic perforation and abscess formation, from distinctive age groups and varying presentation, although both developed septic shock. The...
Glutaminemia prognostic significance in critical surgical patients - An analysi...
Costa, Beatriz Pinto; Martins, Paulo; Veríssimo, Carla; Simões, Marta; Tomé, Marisa; Grazina, Manuela; Pimentel, Jorge; Sousa, Francisco CastroBackground: Glutamine depletion is common in the critically-ill patients. Glutaminemia lower than 420 μmol/l has been considered as an independent predictive factor of mortality, but the indications for exogenous glutamine supplementation remain controversial. This study intends to determine the glutaminemia profi le in critical surgical patients and to investigate its correlation with the severity indexes and ...
Intestinal dysfunction in the critical trauma patients - An early and frequent ...
Costa, Beatriz Pinto; Martins, Paulo; Veríssimo, Carla; Simões, Marta; Tomé, Marisa; Grazina, Manuela; Pimentel, Jorge; Sousa, Francisco CastroBackground: Small-bowel dysfunction exerts a relevant prognostic impact in the critically ill patients. Citrullinemia has been used in the evaluation of the intestinal function and it is considered an objective parameter of the functional enterocyte mass. Present study proposes to determine the intestinal dysfunction prevalence and the citrullinemia kinetic profi le in severe trauma patients and to investigate ...
Argininemia and plasma arginine bioavailability - predictive factors of mortali...
Costa, Beatriz P.; Martins, Paulo; Veríssimo, Carla; Simões, Marta; Tomé, Marisa; Grazina, Manuela; Pimentel, Jorge; Sousa, Francisco CastroBackground: Arginine is an amino acid determinant in the metabolic, immune and reparative responses to severe trauma. The present study aims to determine argininemia and plasma arginine bioavailability (PAB) in critical trauma patients and to analyze its correlation with prognosis. Methods: A prospective study of 23 critical trauma patients was undertaken. Aminoacidemias were determined, by ion exchange chromat...
Enteric nutrition and esophageal impactation: what relationship.
Caldeira, Ana; Casanova, Paula; Sousa, Rui; Martins, Paulo; Banhudo, António; Pimentel, JorgeIn the intensive care unit (ICU), enteral feeding is the method of choice for providing adequate nutrition in intubated patients. The oesophageal impactation (EI) by enteric nutrition (EN) results from solidification of the solution in esophagus lumen with formation of bezoar and although rare, is gradually becoming more common in clinical practice. In recent years some have been diagnosed cases of enteric nutr...
Catastrophic primary antiphospholipid syndrome.
Casanova, Paula; Baptista, João P; Andrade, Maria J; Martins, Paulo; Almeida Sousa, J P; Fernandes, Victor; Simões, Armindo; Souto Gonçalves, JúlioCatastrophic antiphospholipid syndrome develops in a minority of patients with antiphospholipid syndrome, and is characterized by acute thrombotic microvasculopathy with multiorganic involvement (three or more organs). The aetiology is unknown, the diagnosis is complex, and the treatment is empiric, mortality may approach 50%. The authors present a clinical case of catastrophic antiphospholipid syndrome, diagno...
