Pancreaticoduodenectomy with Anatomical Vascular Variant in Groove Pancreatitis-A Case Report.

Groove pancreatitis represents a chronic focal form of pancreatitis affecting the zone between the pancreatic head and the duodenal "C" loop, known as the groove area. This is a rare condition that affects the pancreatic periampullary part, including the duodenum and the common bile duct, which is usually associated with long-term alcohol and tobacco misuse, and is more frequent in men than in women. The most common clinical symptoms of groove pancreatitis include weight loss, acute abdominal pain, nausea, and jaundice. This report is about a 66-year-old woman with a history of heavy smoking, presenting with weight loss, nausea, and upper abdominal pain. Contrast-enhanced computed tomography revealed the existence of chronic pancreatitis as well as the dilatation of the main pancreatic duct, a cyst of the pancreatic head, and enlargement of the biliary tract. Conservatory treatment was initiated but with no improvement of symptoms. Since endoscopic retrograde cholangiopancreatography was not possible due to the local changes, we decided to perform pancreatoduodenectomy, as surgery appears to be the single effective treatment.

Modulation of the Redox Expression and Inflammation Response in the Critically Ill Polytrauma Patient with Thoracic Injury. Statistical Correlations between Antioxidant Therapy.

BACKGROUND: One of the major causes of mortality in the world is represented by multiple traumas. Thoracic trauma is commonly associated with polytraumas. A series of physiopathological complications follow polytraumas, leading to a significant decrease in the survival rate. As a result of injuries, significant quantities of free radicals (FR) are produced, responsible for oxidative stress (OS). To minimize the effects of OS, we recommend the administration of antioxidant substances. In this study we want to highlight statistically significant correlations between antioxidant therapy and a series of clinical variables. METHODS: This retrospective study included 132 polytrauma patients admitted to the ICU-CA between January 2013 and December 2014. The selection criteria were: injury severity score (ISS) ≥ 16, ≥ 18 years, presence of thoracic trauma (abbreviated injury scale, AIS ≥ 3). Eligible patients (n = 82) were divided into two groups: Group 1 (n = 32, antioxidant free, patients from 2013) and Group 2 (n = 50 antioxidant therapy, patients from 2014). Antioxidant therapy consisted in the administration of vitamin C (i.v.), vitamin B1 (i.v.), and N-acetylcysteine (i.v.). Clinical and biological tests were repeated until discharge from ICU-CA or death. RESULTS: Between Group 1 and Group 2 statistically significant differences were highlighted regarding the ISS score (p = 0.0030). 66% of patients from Group 2 were admitted at more than 24 hours after the trauma, in contrast to the patients from Group 1, where 62.5% were directly admitted to the ICU (p = 0.0114). Compared with the patients from Group 1, patients who received antioxidant therapy show improved parameters: leukocytes (p < 0.0001), platelets (p = 0.0489), urea (p = 0.0199), total bilirubin (p = 0.0111), alanine transaminase (p = 0.0010), lactat dehydrogenase (p < 0.0001). Between the two groups there were no statistically significant differences regarding the length of stay in the ICU-CA (p = 0.4697) and mortality (p = 0.1865). CONCLUSIONS: Following the study, we can affirm that due to the administration of antioxidant substances, posttraumatic complications are greatly reduced. Moreover, the administration of high dose of antioxidants remarkably improves the clinical status of the critical patient.

Using Circulating miRNAs as Biomarkers for the Evaluation and Monitoring of the Mitochondrial Damage in the Critically Ill Polytrauma Patients.

BACKGROUND: The multiple-traumatic critical patient presents a variety of pathophysiological, cellular, and molecular dysfunctions. One of the most important is represented by mitochondrial damage which afterwards is responsible for the augmentation and worsening of a series of pathologies that lead to the worsening of the clinical status of the patient. The severe inflammatory response, sepsis, and the redox imbalance are other pathologies that together with the multiple traumas are responsible for the mitochondrial dysfunctions. As an overview, we can say that both the mitochondrial damage as well as the clinical statuses of those patients are responsible for an increase in the chances of multiple organ dysfunction syndrome and death of critical patients with multiple trauma from the Intensive Care Units (ICU). In this paper we wish to summarize the microRNAs that can be used as biomarkers for evaluation and monitoring of the mitochondrial activity in critical patients with multiple traumas. METHODS: For the paper, literature available in the international databases PubMed and Scopus until the year 2015 has been consulted. The key words used for the article search were "mitochondrial damage", "microRNAs biomarkers", and "critically ill polytrauma patients". RESULTS: As a result of the research based on the key words presented above, we found 234 papers. From those, after rigorous analysis 64 were selected as being in conformity with the needs of this paper. CONCLUSIONS: The critical polytrauma patient needs a specific evaluation and monitoring due to the complexity of the dysfunctions that appear at the cellular level. The use of microRNAs as biomarkers for the mitochondrial damage can be of real use for intensive care medicine. Nevertheless, more studies are required in order to determine a larger panel of microRNAs which can have an impact on mitochondrial damage.
