Interdisciplinary Management of Visceral Artery Aneurysms and Visceral Artery Pseudoaneurysms.

The paper presents the results of treating 14 patients, namely eight patients with visceral artery aneurysms and six patients with visceral artery pseudoaneurysms. In 64.3% of the patients, the initial diagnosis was made based on the ultrasound examination. All the patients (100%) underwent CT angiography, while angiography was performed in 71.4% of the cases. Five (35.7%) patients with visceral artery pseudoaneurysms were emergently hospitalized; among them, the signs of bleeding were observed in 2 patients. In 9 patients, pathology was detected during tests for other conditions. Five (35.7%) patients underwent endovascular treatment, while 9 (64.3%) patients received surgical treatment. Endovascular interventions and open surgery demonstrated a nil mortality rate. After endovascular treatment, stent thrombosis was found in 1 patient. In the case of surgical treatment, visceral artery aneurysm was observed in 1 patient who underwent the resection of superior mesenteric artery pseudoaneurysm. Conclusions. The choice of the method of treating visceral artery aneurysms and visceral artery pseudoaneurysms depends on the location, size, anatomic features of the visceral arteries and the clinical course of the disease. Both endovascular and surgical treatment demonstrate good postoperative outcomes. Visceral ischemia is one of the most serious complications in the postoperative period, which can complicate both the diagnosis and the choice of treatment tactics.

Obesity as a risk factor for severe acute pancreatitis patients.

BACKGROUND: Obesity plays an important role in increasing the risks of cardiovascular diseases, metabolic diseases, and death. Controversy persists concerning the degrees to which obesity influences mortality and morbidity in severe acute pancreatitis. MATERIALS AND METHODS: Between 2008 and 2012, the findings of 384 consecutive acute pancreatitis patients were analyzed in a prospective trial. Ranson's scores, Acute Physiology And Chronic Evaluation II scores, and computed tomography severity indexes were calculated. Patients were categorized by body mass index (BMI) and waist circumference for the analysis. The aim of this study was to investigate the influence of obesity on local and systemic complications as well as on mortality in severe acute pancreatitis patients. RESULTS: Severe acute pancreatitis was confirmed in 91 (23.7 %) patients. Local and systemic complications were recorded in 64 (16.7 %) and 51 (13.3 %) patients, respectively. Obesity calculated by BMI was identified as a significant risk factor for local and systemic complications (p < 0.02 and p < 0.03, respectively). Moreover, in this study, obesity was also categorized by waist circumference and was confirmed as a risk factor (p < 0.01). The overall mortality rate was 2.4 %, i.e., nine patients died. This study indicates that obesity can have a statistically significant influence on the mortality of severe acute pancreatitis patients. CONCLUSIONS: The presence of obesity has a negative impact on the survival rate of severe acute pancreatitis patients. Obese patients have higher incidence of local and systemic complications. Obesity seems to be a negative prognostic factor in severe acute pancreatitis patients.

Perioperative and follow-up results in chronic pancreatitis patients after pancreatic resection.

BACKGROUND/AIM: Surgical therapy for chronic pancreatitis is reserved for patients with intractable abdominal pain, complications of the disease, or suspected underlying carcinoma. Pancreatic resection can be performed safety with good postoperative results. METHODS: Between January 1996 and December 2009, the findings for 90 consecutive patients suffering from chronic pancreatitis were analyzed in prospective trial. Short-term results - postoperative complications were investigated 30 days after surgery. Long-term follow-up results, including quality of life (QoL) assessment using visual analog scale of pain (VAS), Karnofsky performance scale (KPS), and EORTC Quality of Life Questionnaire (QoL-C30) were carried out. The influence of postoperative complications on long-term quality of life was documented. RESULTS: The overall mortality rate and morbidity rate were 3.3% (3 patients) and 27.7% (25 patients), respectively. Surgically related morbidity rate was 21.1% (19 patients). Long-term follow-up was investigated in 65 patients (72%). The median pain score decreased using VAS from 8 to 1 and using KPS increased from 50 to 100 (p < 0.0001). During the follow-up, the median global QoL improved by 100%. Apart from the cognitive functioning, the physical status, working ability, and emotional and social functioning all improved significantly (p < 0.0001). The presence of postoperative complications had no significant influence on long-term quality of life. CONCLUSION: Surgery for patients with chronic pancreatitis can be performed safely with minimal morbidity and very good long-term results.

[Have changes in the management of treatment of the patients with acute pancreatitis brought the expected result?]. / Priniesla zmena manazmentu u chorých s t'azkou akútnou pankreatitídou ocakávaný výsledok?

BACKGROUND: Mortality from severe acute pancreatitis (AP) has remarkably decreased (10-20%) during the last decades. However, many questions on the treatment of this disease remained opened. To extend the most recent professional literature which discuses the abovementioned problem, experience from the treatment of patients at the department where the authors work is presented. METHODS: Influenced by the new methods published in professional literature and under the circumstances at own workplace, the decision to change the management of the treatment of AP has been made. The management referred to the enteral nutrition, epidural analgesy, antibiotic prophylaxis, pushing the surgical operation to the later period in the case of infected necrosis. Comparing of two groups of patients--A (2003-2005 years) and B (2006-2008 years) the authors came to interesting results. RESULTS: Applying the new protocol we observed: increased percentage of patients with sterile necrosis from 46% to 58%, decreased number of surgical re-operations from 43% to 33% and decreased mortality from 53,8% to 18%. CONCLUSIONS: Applying changes in the management of treatment of the patients with the complicated form of acute pancreatitis, the authors achieved remarkable results. Nevertheless, these results have to be evaluated very cautiously, because the group of patients who have been treated by the novel approach has not been very large.

Effects of equal daily doses delivered by different power densities of low-level laser therapy at 670 nm on open skin wound healing in normal and corticosteroid-treated rats: a brief report.

The optimal parameters for low-level laser therapy (LLLT) for wound healing are still open to discussion. Hence, our study was aimed at comparing the effects of different power densities of LLLT at 670 nm in rats. Four round full-thickness skin wounds were placed on the backs of 16 rats which were divided into two groups (non-steroid and steroid-treated). Three wounds were stimulated daily with a diode laser (daily dose 5 J/cm(2)) at different power densities (5, 15 and 40 mW/cm(2), respectively), and the fourth wound served as a control. Six days after surgery all animals were killed and samples removed for histological evaluation. Significant acceleration of fibroblast proliferation and new vessel formation was observed in wounds treated at the selected power densities. No significant differences were found in corticosteroid-treated rats. In conclusion, LLLT with the methodology used improved wound healing in non-steroid rats, but was not effective after corticosteroid-treatment.

Polymorphisms of the XRCC1 and XPD genes and breast cancer risk: a case-control study.

The purpose of this case control study was to evaluate the role of X-ray repair cross-complementing group 1 (XRCC1) and xeroderma pigmentosum group D (XPD) genotypes as genetic indicators of susceptibility to breast cancer (BC). We analysed DNA samples from 114 breast cancer patients and 113 control subjects using polymerase chain reaction-restriction fragment length polymorphism. For the single nucleotide polymorphisms in XRCC1 exon 10 (Arg399Gln, G/A) and XPD exon 23 (Lys751Gln, A/C), no remarkable differences for genotype distribution and allele frequencies were observed between BC group and control group in the study. The genotype frequency for homozygote A/A in XPD exon 6 (Arg156Arg, C/A) were significantly different between BC and control groups (P < 0.0001, odds ratio = 2.14; 95% confidence interval 1.44-3.17). The data indicate a possible role for XPD (Arg156Arg, C/A) polymorphisms in BC susceptibility.
