Background: Surgical trauma triggers an important postoperative stress response characterized by significantly elevated levels of cytokines, an event that can favor the emergence of immune disorders which lead to disturbances in the patient's body defense. The magnitude of postoperative stress is related to the degree of surgical trauma. Aim: To evaluate the expression of pro-inflammatory (TNF-α, IFN-γ, IL-1β, and IL-17) and anti-inflammatory (IL-4) cytokines in patients submitted to conventional and single-port laparoscopic cholecystectomy before and 24 h after surgery...

Renal ischemia/reperfusion (I/R) damage may arise due to nephron sparing surgery in patient with a solitary kidney of restricted renal parenchymas. Apoptosis, inflammation and oxidative stress play a significant role in the expansion of renal dysfunction following renal I/R. The aim of the current investigation was to particularize the potential effect of curcumin against hypoxia induced renal injury. The albino Wistar rats divided into groups and each group contains six rats. They groups are normal control; disease control; curcumin (5 mg/kg per day) and another group orally treated with curcumin (10 mg/kg per day) for two weeks before induction of renal I/R...

OBJECTIVE: After stent or bypass surgery blood pressure (BP) can go up for multiple reasons among which are: stress and tense of the patient unsure about the future, the pain of the cut and because some of the blood pressure medication, which the patient was receiving preoperatively may get withdrawn post operatively, thereby leading to shooting up the BP. In certain patients, BP actually comes down after surgery and returns back to the pre-operative levels 4 to 6 weeks down the track...

OBJECTIVE: A safe and optimal pneumoperitoneal pressure (PP) for laparoscopic renal surgery in infants is difficult to define. In a broad sense, a safe and optimal PP should cause least intraoperative and postoperative physiological stress for the infants and should be optimal for surgeon's technical feasibility. Unfortunately, the safe and optimal PP in infant for transperitoneal laparoscopic surgery has not been established by well validated study. To determine safe and optimal PP for laparoscopic renal surgery (LRS) in infants less than 10 kg...

BACKGROUND AND AIMS: Perioperative stress is an often ignored commonly occurring phenomenon. Little or no prior knowledge of anesthesia techniques can increase this significantly. Patients awaiting surgery may experience high level of anxiety. Preoperative visit is an ideal time to educate patients about anesthesia and address these fears. The present study evaluates two different approaches, i.e., standard interview versus informative audiovisual presentation with standard interview on information gain (IG) and its impact on patient anxiety during preoperative visit...

The aim of this study was to evaluate the protective effects of resveratrol and curcumin in an experimental rat model of intestinal ischemia-reperfusion (I/R). Forty-eight adult Wistar rats were used: 12 animals undergoing the sham surgery and 36 animals undergoing laparotomy, with 15 min of mesentric artery clamping. The animals from the latter group (n = 12) were pretreated, for 1 week, with vehicle (CTR), resveratrol (RES), and curcumin (CUR). After 1 h and 6 h of reperfusion, respectively, cyclooxigenase (COX)-2, mucin-1, E-cadherin, nuclear factor (NK)-κB expressions, and tumor necrosis factor related apoptosis-inducing ligand (TRAIL) were assessed in the small intestine...

Life threatening conditions characterized by renal ischemia/reperfusion (RIR) such as kidney transplantation, partial nephrectomy, renal artery angioplasty, cardiopulmonary bypass and aortic bypass surgery, continue to be among the most frequent causes of acute renal failure. The current study investigated the possible protective effects of tadalafil alone and in combination with diltiazem in experimentally-induced renal ischemia/reperfusion injury in rats. Possible underlying mechanisms were also investigated such as oxidative stress and inflammation...

BACKGROUND: Transversus abdominis plane block (TAP) is a compartmental block of the anterior abdominal wall. Surgical trauma produces multisystem reactions. Anesthetic techniques can modify the neuroendocrine surgical stress response. AIM: The aim of this study was to evaluate the effect of TAP block on the modification of the surgical neuroendocrine stress response as well as its analgesia effect in children undergoing open inguinal hernia repair. METHOD: Sixty children aged 3-10 years undergoing elective unilateral open inguinal hernia repair were randomized into group I (general anesthesia) or group II (received TAP block after induction of general anesthesia)...

BACKGROUND: Polyunsaturated fatty acids (PUFAs) play various roles in inflammation. However, the effect of PUFAs in the development of reflux esophagitis (RE) is unclear. This study is to investigate the potential effect of n-3/n-6 PUFAs on acute RE in rats along with the underlying protective mechanisms. METHODS: Forty Sprague Dawley rats were randomly divided into four groups (n = 10 in each group). RE model was established by pyloric clip and section ligation...

BACKGROUND: It has been reported that higher levels of oxidative stress and inflammation play a key role in the progression of hepatocellular carcinoma (HCC) after surgery. Coenzyme Q10 is an endogenous lipid-soluble antioxidant. To date, no intervention study has investigated coenzyme Q10 supplementation in HCC patients after surgery. The purpose of this study was to investigate oxidative stress, antioxidant enzymes activity, and inflammation levels in HCC patients after surgery following administration of coenzyme Q10 (300 mg/day)...

Functional capacity has been shown to be a major determinant of surgical outcome since it is related to postoperative complications, activity and daily function, level of independence and quality of life. Anesthesiologists as "perioperative physicians", can identify those scoring systems that assess functional capacity, whether from the basic physical history and walk test to the most complex such as cardiopulmonary exercise testing (CPET), and formulate intraoperative and postoperative interventions (rehabilitation) to minimize the impact of surgery on the recovery process...

: Prior studies have suggested that elevated serum Troponin-I (TnI) levels immediately after non-cardiac surgical procedures (8-40%) represent subclinical cardiac stress which independently predicts increased 30-day mortality. Routine post-operative TnI monitoring has therefore been suggested as a standard of care. However, no prior studies have focussed on elective degenerative spine surgery, whilst few have measured pre-op TnI. Further, prolonged prone positioning could represent an additional, independent, cardiac stress...

OBJECTIVE: To investigate the association between urinary neurotrophin levels, maximum flow rate (Qmax) variation and the appearance of urgency in women with stress urinary incontinence (SUI) after a midurethral sling (MUS) procedure. METHODS: Thirty-one women with SUI were treated with a MUS. One year later, the outcome of surgery and the onset of urgency were assessed. At baseline and 1-year follow-up, urine was collected to measure nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) concentration, and Qmax variation was calculated...

Growing evidence underscores the important role of glycemic control in health and recovery from illness. Carbohydrate ingestion in the diet or administration in nutritional support is mandatory, but carbohydrate intake can adversely affect major body organs and tissues if resulting plasma glucose becomes too high, too low, or highly variable. Plasma glucose control is especially important for patients with conditions such as diabetes or metabolic stress resulting from critical illness or surgery. These patients are particularly in need of glycemic management to help lessen glycemic variability and its negative health consequences when nutritional support is administered...

BACKGROUND: Hurthle cells of the thyroid gland are very rich in mitochondria and oxidative enzymes. As a high level oxidative metabolism may lead to higher level of oxidative stress and can be associated with an increased risk for cancer, we investigated whether common functional polymorphisms in antioxidant genes (SOD2, CAT, GPX, GSTP1, GSTM1 and GSTT1) are associated with the development or clinical course of Hurthle cell thyroid carcinoma (HCTC). METHODS: A retrospective study was performed in 139 patients treated by thyroid surgery for a Hurthle cell neoplasm...

BACKGROUND: The ideal femoral component for revision THA is undecided. Cylindrical nonmodular stems have been associated with stress shielding, whereas junctional fractures have been reported with tapered fluted modular titanium stems. We have used a tapered fluted nonmodular titanium femoral component (Wagner Self-locking [SL] femoral stem) to mitigate this risk. This component has been used extensively in Europe by its designer surgeons, but to our knowledge, it has not been studied in North America...

AIM: Phantom rectum is the sensation of an intact and/or functioning rectum, despite excision at surgery. Abdominoperineal excision of the rectum (APER) may be complemented by reconstructive operations and recently it was reported that patients undergoing APER and vertical rectus abdominis myocutaneous (VRAM) flap reconstruction are more prone to develop phantom sensations at an earlier timeframe and have more persistent symptoms than those who do not have perineal repairs. The aim of this study was to determine the prevalence of phantom rectal sensations in a cohort of these patients...
