To determine the safety and feasibility of solo laparoscopic appendectomy, which is defined as the application of solo surgery to laparoscopic appendectomy, by comparing consecutive non-solo procedures conducted by a surgeon in the presence or absence of human assistant(s).
Recent advances in thoracoscopic surgery have made it a commonly used technique for treating spontaneous pneumothoraces and preventing recurrence. The goal of surgical treatment is to find the offending bleb, remove it, and do some manipulation to encourage pleural symphysis. Methods of thoracoscopic pleural symphysis have included mechanical abrasion and instillation of chemical irritants. Each method reduces the rate of pneumothorax recurrence to a certain degree, but the recurrence rates after thoracoscopic surgery are widely varied in the literature. Although several articles show significantly lower rates, there are also articles demonstrating that the recurrence rates of pneumothorax after thoracoscopic surgery ranged between 5 and 12%, which are higher than the rates reported after open thoracotomy. It is suggested that a less intense pleural inflammatory reaction is induced by thoracoscopic procedure than by thoracotomy. Besides, post-pleurodesis severe pain and bleeding were encountered frequently. A potential alternative to increase the intensity of pleural inflammation and thereby prevent pneumothorax recurrence is film pleurodesis. Only few studies have been reported where more than one film pleurodesis has been tried, and the mechanism of film pleurodesis remains unclear. Poly-ε-caprolactone (PCL) is a FDA-approved biomaterial with a slow degradation time of approximately 24 months when degraded by hydrolysis only. Recently, some investigators combined PCL with other biomaterials such as chitosan, polyethylene glycol, hyaluronic acid to produce anti-adhesion barrier for clinical applications. However, only few studies report PCL only could provide anti-adhesion effect. In contrast to common complications of postoperative abdominal adhesions, adhesion (or pleurodesis) is an important therapeutic tool to control the incidence of recurrent pneumothorax. We suppose that if a biomaterial induces adhesion following abdominal surgery, perhaps it may be applied to pleurodesis tool for preventing recurrence of spontaneous pneumothorax. We hypothesized that PCL membrane-induced pleurodesis can be achieved intrapleurally.

Intraoperative judgement of lesions excision, residual parts, visualization and operative corridor pre and after endoscope introduction. 2. Post-operative tumor control confirmed comparison between pre and postoperative MRI. 3. Postoperative complications, advantages and disadvantages compared with these when use pure microscopic excision from the literature
Tourniquet is widely used in orthopedic surgery. However, prolonged tourniquet inflation may cause a gradual rise in blood pressure, which named as tourniquet-associated hypertension. Thus, to effectively prevent the tourniquet related hemodynamic responses is important for patients receiving limb surgery. Tracleer is an endothelin receptor antagonist indicated for the treatment of pulmonary arterial hypertension. Tracleer can also be used to treat retistant hypertension. At present trial, the investigators are going to investigate the effect of Tracleer on tourniquet-associated hypertension during total knee arthroplasty.
Lung cancer is a leading cause of cancer mortality among adults worldwide. The incidence rates of lung cancer among never smoking females in some parts of East Asia are among the highest in the world. The adenocarcinoma of lung being the most frequently identified histological type is more weakly associated with smoking, and often occurs in females and never-smokers. Although family history of lung cancer has been associated with histological subtypes, the inherited susceptibility factors that affect specific histology are unknown. Genetic factors that determine individual predisposition to lung cancer have been identified via genome-wide association studies. These known common loci, however, explain only a small fraction of the familial risk of lung cancer. The hypothesis of this study is that there are genetic factors that confer inherited susceptibility among patients with primary non-small-cell lung cancer (NSCLC).
Admission CTG for 20 minutes Settings on a CTG machine was standardised to enable a consistent approach of interpretation of traces. Paper speed of 3cm per minute will be adopted. Maternal heart rate was recorded and noted on CTG. Following birth date, time and mode of delivery will be labelled on CTG. Magnesium sulphate was administered by continuous intravenous infusion according to our hospital protocol as follows: - Loading dose: 4-6 gm of magnesium sulphate diluted in 100 mL of IV fluid administered over 15-20 min. - Maintenance dose: 2 gm/hr in 100 mL of IV infusion to be continued for 24 hours after delivery. Another 20 minutes CTG strip will be performed 20 minutes after administration of IV loading MgSO4, 7H2O and thus ensuring that MgSO4 has reached peak serum levels
The purpose of the research is to investigate the effects of respiratory training on respiratory and functional performance in patients with stroke.
The increase in the prevalence of diabetes mellitus (DM) is one of the greatest public health challenges worldwide. Epidemiological studies have shown that DM is the leading cause of chronic kidney disease (CKD) in patients initiating renal replacement therapy. In our country, diabetes accounts for about 60% of all incidents of dialysis. On the other hand, CKD is currently considered a noxious disease because patients not only have the likelihood of progression to end-stage renal disease (ESRD), but because these renal alterations are associated with an increased risk of cardiovascular complications and premature death for the same cause. Most studies have focused on traditional risk factors (poor diet, physical inactivity and obesity) for the development and progression of renal damage, and less information exists on non-traditional factors such as oxidative stress and mainly, the low antioxidant response that characterizes both DM and nephropathy. In addition, there is a great variation in the susceptibility to and progression of kidney disease between different populations that is not explained by the presence of traditional factors and that could be triggered by genetic variations and its interaction with other components related to the environment and lifestyle. Fortunately, there is sufficient scientific evidence that early detection and modification of negative lifestyle factors can not only delay or halt the progression of the renal function decline to ESRD but can also significantly reduce the incidence of cardiovascular disease leading to premature death in most of these patients. Therefore, it is suggested that this risk may be determined by the interaction of lifestyle factors with the presence of susceptibility alleles, which may vary from one population to another. It is now known that hyperglycemia causes a state of oxidative stress and inflammation that can be counteracted by diet supplementation with some natural antioxidants such as curcumin. It has been shown that this molecule has multiple pharmacological properties: antioxidant, anti-inflammatory, cardioprotective, renoprotective, among others. In clinical trials a positive effect of curcumin has been seen in the treatment of diabetes and its complications. This has generated a relative optimism in the search for new curcumin treatment targets where oxidative stress is of great relevance, as is the case with CKD. However, there are still doubts about its efficacy as an adjuvant in the prevention of CKD. Additionally, the role played by interindividual variability in genes involved in the mechanism of action of curcumin is still incipient, more studies in this knowledge area are necessary.
The surgical technique used in liver transplantation has undergone constant Evolution in an effort towards towards a safe, highly standardized procedure. Despite this, the initial step of the recipients' hepatectomy has not been in the focus of clinical research thus far. Due to usually advanced coagulopathy in liver transplantation recipients, this part of the operation still bares the risk of severe hemorrhage. This trial is designed to compare an electrothermic, bipolar vessel sealing device (LigaSureTM) and an ultrasound dissector (HARMONIC ACE®+7) to standard surgical techniques during the recipients' hepatectomy in liver transplantation. In a single center, prospective, randomized, controlled, parallel three armed, confirmatory, open trial, LigaSureTM and HARMONIC ACE®+7 will be compared to standard surgical techniques which, utilize titanium clips and conventional knot tying ligations during the recipients' hepatectomy in liver transplantation. Intraoperative total blood loss is the primary endpoint of the trial. Secondary endpoints include blood loss during the hepatectomy, the duration of both the hepatectomy and the entire surgical procedure, as well as blood transfusion requirements of the procedure. To generate reliable data, intraoperative blood loss will be recorded with respect to all rinse fluids during surgery, ascites and by weighing used swabs to generate reliable data. At 80% power and an alpha of 0.025 for both either of the experimental groups, twenty-three subjects will be analysed per protocol in each study arm in order to detect a clinically relevant reduction of intraoperative blood loss. The intention to treat analysis will include sixty-nine patients. The follow up period for each patient will be 90 days for safety reasons, whereas all clinical outcomes will be measured within the first ten postoperative days. This is the first prospective, randomized trial comparing two innovative, technical methods of vessel sealing and dissection against standard techniques for recipient hepatectomy. This will be done to detect a relevant reduction of intraoperative blood loss during liver transplantation.The results of the trial are expected to improve patients' outcome and safety after liver transplantation and to increase the general safety of this procedure.
