Clinical relevance of IL-6 gene polymorphism in severely injured patients

In polytrauma, injuries that may be surgically treated under regular circumstances due to a systemic inflammatory response become life-threatening. The inflammatory response involves a complex pattern of humoral and cellular responses and the expression of related factors is thought to be governed by genetic variations. This aim of this paper is to examine the influence of interleukin (IL) 6 single nucleotide polymorphism (SNP) -174C/G and -596G/A on the treatment outcome in severely injured patients. Forty-seven severely injured patients were included in this study. Patients were assigned an Injury Severity Score. Blood samples were drawn within 24 h after admission (designated day 1) and on subsequent days (24, 48, 72 hours and 7 days) of hospitalization. The IL-6 levels were determined through ELISA technique. Polymorphisms were analyzed by a method of Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR). Among subjects with different outcomes, no statistically relevant difference was found with regards to the gene IL-6 SNP-174G/C polymorphism. More than a half of subjects who died had the SNP-174G/C polymorphism, while this polymorphism was represented in a slightly lower number in survivors. The incidence of subjects without polymorphism and those with heterozygous and homozygous gene IL-6 SNP-596G/A polymorphism did not present statistically significant variations between survivors and those who died. The levels of IL-6 over the observation period did not present any statistically relevant difference among subjects without the IL-6 SNP-174 or IL- 6 SNP -596 gene polymorphism and those who had either a heterozygous or a homozygous polymorphism.

Glissonean pedicle approach in major liver resections.

BACKGROUND/AIMS Liver resections are still one of the most challenging operations. The aim of this study was to analyze the efficiency and safety of the intrahepatic Glissonean pedicle approach vs. classical Hilar dissection in major hepatectomies. METHODOLOGY Thirty-four patients were assigned to the Glissonean approach (GA, n=34), while the Hilar dissection were assessed as historical control, matched for the age, gender, comorbidities and Child-Pugh score (HD, n=34). RESULTS The GA was associated with significantly shorter surgery duration (191.18±41.10 vs. 246.62± 56.55), transection time (38.94±14.56 vs. 56.32±19.40) and ischemic duration (26.03±11.27 vs. 41.18±12.80) than HD (p<0.001 for all). The amount of blood loss was significantly lower in GA (245.59±169.39 vs. 344.71±166.25; p=0.018). The amount of blood transfusion was significantly lower in GA during surgery (322.86±102.07 vs. 414.76±135.48) as well as postoperatively than HD (246.67±5.77 vs. 336.67±120.55) (p=0.038 and p=0.026. respectively). CONCLUSIONS Major hepatectomy can be performed more easily using the Glissonean pedicle approach than by hilar dissection. En-masse transection of pedicles, as well as hepatic veins, using endo-GIA vascular stapler could be performed safely. Liver surgeons should know the Glissonean pedicle approach.

Eritropoetin u procjeni ishoda liječenja kod bolesnika s politraumom

Polytrauma is a term describing patients with injuries involving multiple body regions that compromises function of the body and/or organ involved. The aim of the study was to evaluate the potential role of erythropoietin in predicting poorer outcome in trauma patients. This prospective study included 86 patients admitted to the Emergency Center of Serbia due to polytrauma assigned according to Injury Severity Score (ISS). The patients were further evaluated using the Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores and erythropoietin levels. There was a significant difference among erythropoietin levels at admission, after 48 and 72 hours, and on day 7 of hospital stay, with significantly higher levels in patients with ISS values 49-75. Based on the results, ROC curves were used to identify cut-off levels to predict ISS score with critical clinical course. It was concluded that erythropoietin could be a good marker of injury severity. Further research has to be performed to determine the cut-off values of erythropoietin that are significant for injury severity.

Challenges and advances in the care of injuries in the Republic of Serbia

There are many problems that trauma care system in Serbia is facing today. Few of them are: 1) Lack of categorization of trauma centers; 2) Diversity in managing of trauma patients among institutions; 3) There is no trauma management training, 4) Inappropriate cooperation between pre hospital trauma care and hospital trauma care; 5) There is no standard in managing of trauma patients as well as procedures. To improve trauma care quality throughout the country we must learn from the experiences of other countries. The aim of this paper was to report representative data about organization, management, stuff and equipment of ambulance and emergency services in Serbia. We analyzed 12 out of 138 parameters we obtained from the relevant institutions.

Previdi u zbrinjavanju teško povređenih

Question of missed injuries is more offen a question of human errors: task execution errors, procedural errors, communication errors, decision errors and noncompliance. Missed injuries are those which are not identified in the first three days of hospitalization. This theme is not popular among physicians. Literature data mention percent from 3 - 29% missed injuries overall. The underlying causes errors are: false attributin, false negative prediction and false lebeling. False attribution involves a tendency to incorrectly link a clinical observation with an arroneous cause. This tendency also ignores one of the fundamental principles of the management of traumatic injury: that the index of suspicion should proceed on the basis of assumed wors resonable case scenario. Weaknesses of traumasistems: high patients volume, high-risk patients, long hours, changing set of resources, and problems sush bad admission planing, defficite anamnesis, defficite diagnostic procedures, bad communication, improvisation etc.
