Near infrared light examination as part of the management of sporadic pancreatic head insulinoma: Case report.

INTRODUCTION: We report the case of a 77-year-old female patient with the diagnosis of pancreatic head insulinoma, in whom we used near infrared light (NIR) to detect synchronous pancreatic tumors and potential secondary lymph node or liver involvement. The patient presented with hypoglycemia manifesting by lipothymia. With the diagnosis of secretory neuroendocrine tumor (insulinoma) of the pancreatic head, cephalic pancreatoduodenectomy with the preservation of the pylorus was performed after NIR visualization of the pancreatic tumor mass. At 6, 12, 18 months postoperatively, the patient no longer had hypoglycemia and her general state was good. CONCLUSION: NIR with indocyanine green (ICG) evidences pancreatic neuroendocrine tumors, as well as possible synchronous tumors and secondary lymph node or liver involvement.

Surgical technique of concomitant laparoscopically assisted vaginal hysterectomy and laparoscopic cholecystectomy.

BACKGROUND: Laparoscopically assisted vaginal hysterectomy is one of the most frequently performed gynecologic operations, and numerous authors have demonstrated its safety and feasibility. CASE PRESENTATION: We practiced in some selected cases simultaneous laparoscopically assisted vaginal total hysterectomy with bilateral adnexectomy and laparoscopic cholecystectomy using 5 trocars without uterine manipulator. Previous examinations included abdominal ultrasound, cervix biopsy and CT of abdomen and pelvis. Our aim was to evaluate the surgical technique of our initial experiences for combined laparoscopically assisted vaginal hysterectomy and laparoscopic colecystectomy. CONCLUSIONS: Laparoscopic hysterectomy had a number of advantages over the conventional technique given the underlying associated diseases, postoperative pain, rapid recovery and aesthetic benefits.

Influence of risk factors and comorbidities on the successful therapy and survival of patients with critical limb ischemia.

BACKGROUND: Critical limb ischemia (CLI) is associated with an increased risk of limb amputation, low quality of life and cardiovascular death. The aim of this study is to identify the prognostic factors of mortality, revascularization failure and amputation failure, as part of risk factors for athero-sclerosis and comorbidities. PATIENTS AND METHODS: We examined 198 patients operated for CLI. Cox analysis was performed to discern the factors that were associated with failure of initial surgical therapy and death. RESULTS: For survival analysis, a significant model emerged with hypertension (p=0.00), cardiac comorbidities (p=0.00), renal comorbidities (p=0.04) and respiratory comorbidities (p=0.02) as significant predictors. Regarding the time to amputation failure, there was a significant model with insulin treated diabetes (p=0.00), coronary artery disease (p=0.02) and cerebrovascular disease (p=0.05) as significant predictors. CONCLUSIONS: Significant predictors for mortality in CLI patients are high risk hypertension, severe coronary artery disease, renal failure requiring dialysis and chronic obstructive pulmonary disease. The association of these prognostic factors results in a proportional decrease of survival. The predictors for amputation failure were, in addition to local factors, insulin treated diabetes, coronary artery disease and cerebrovascular disease. The revascularization for limb salvage depends on the correct indication and accurate surgical technique.

Influence of sildenafil and donepezil administration on the serum redox balance in experimentally induced lower limb critical ischemia.

INTRODUCTION: Chronic lower limb ischemia (CLLI) leads to endothelial cell dysfunctions and endothelial lesions. The use of substances that release nitric oxide and activate endothelial nitric oxide synthase has proved to be useful in increasing angiogenesis and arteriogenesis under critical ischemia conditions. OBJECTIVES: To investigate the therapeutic effect of Sildenafil and Donepezil with a vasodilating action in experimentally induced CLLI and on serum redox homeostasis. MATERIAL AND METHOD: The research was performed in 3 groups of rats (n=10 animals/group) with experimentally induced CLLI: group I - control group; group II - animals treated postoperatively with a therapeutic dose of sildenafil, and group III - animals treated postoperatively with a therapeutic dose of donepezil. Oxidative stress (OS) indicators (malondialdehyde - MDA, protein carbonyls - PC), antioxidant (AO) defense indicators (reduced glutathione - GSH and oxidized glutathione - GSSH), and ceruloplasmin (CP) were determined on days 7, 14, 21 and 30. Statistical processing was performed using the Excel application (Microsoft Office 2007), with the StatsDirect v.2.7.2 software. RESULTS: Changes in OS were evidenced in all groups on account of a decrease in MDA and PC. The greatest OS decrease in all groups was on day 30. AO defence changes were represented by decreased levels of GSH and GSSG in all groups, at the studied moments. Intracellular AO defense in the cytosol, nucleus and mitochondria was similar in all groups, (decreased GSH, GSSG and GSH/GSSG ratio). We found increased extracellular levels of GSH, GSSG, and CP and increased extracellular GSH/GSSG ratio at level compared to values on day 7. CONCLUSIONS: 1) The administration of sildenafil (group II) and donepezil (group III) has favorable effects on reducing OS in experimentally induced CLLI. 2) Sildenafil and Donepezil administration stimulates extracellular AO defense on account of CP. 3) Sildenafil and Donepezil administration influences intracellular redox homeostasis on account of the GSH/GSSG couple, the major redox buffer in the body.

Ceruloplasmin - acute-phase reactant or endogenous antioxidant? The case of cardiovascular disease.

Ceruloplasmin is a plasma protein that functions as a copper transporter. Epidemiological studies have indicated an association between the concentration of this protein and risk for cardiovascular disease. The mechanism for the involvement of ceruloplasmin in cardiovascular disease and other conditions is not yet clear, although it is widely accepted that the role played by ceruloplasmin in facilitating or counteracting oxidative stress is central. We review here some of the studies on this issue and try to calm down the duel between the claims supporting the oxidant or the antioxidant effects of ceruloplasmin through a clear-cut analysis of the available data. Our conclusion is that a verdict regarding the pathogenetic involvement of ceruloplasmin in cardiovascular disease should await further research.
