Internal limiting membrane peeling in diabetic vitrectomy will help prevent postoperative epiretinal membrane formation
Gastric variceal bleeding has a very high rebleeding rate even after endoscopic variceal injection of cyanoacrylate (GVO) which is considered the first choice of endoscopic treatment. Beta-blocker (BB) is effective to lower portal pressure. We hypothesized combination of GVO and BB can further decrease the rebleeding rate.
A relevant reduction of blood pressure (BP) in placebo-treated control groups is a phenomenon often observed in pharmacological studies of hypertension. This effect was shown to differ from spontaneous remission tendencies and regression to the mean effect by comparing placebo groups with untreated controls. However, it is not fully understood whether these effects are due to a global reaction of the autonomous nervous system (affecting the overall organ systems of the body) or a specific reaction (affecting the cardiovascular system only). We therefore aim to differentiate specific effects (reduction of blood pressure) from global effects (e.g. changes in electrodermal and gastric activity). In our study we aim to test the following hypotheses: 1. Placebo administration leads to a significant changes of blood pressure compared with untreated controls. 2. The direction of blood pressure change depends on the type of suggestion (either decrease or increase) 3. This effect is specific for blood pressure; changes in electrodermal and gastric activity do not differ between groups. 4. The placebo response can be enhanced by a prestige intervention (information about the suggested drug action given by doctor or in written form).
The purpose of this research study is to determine the genotype (genetic composition) and phenotype (physical appearance) of cells derived from the abdominal cavity to determine whether stem cells are present.
Background: During the repair process of deep venous thrombosis, capillary formation is seen from day 18 to day 25. Contrast agent investigation is well known to detect small vessels in arterial disease. We intend to use this method to detect early vascularisation in the thrombus, in order to get more information about the evolution of the thrombosis in vivo. Aims of the study: Investigation of a newly diagnosed occluding venous thrombus with duplexsonography, using contrast agent and compare the degree of vascularization in the same patient after 3 weeks and 3 months. The relative signal intensity difference (baseline to peak) of the time intensity curve (TIC) is measured in defined region of interests (ROI). Comparison of the visibility of revascularisation between color duplexsonography, power mode and contrast agent will be done. Method: Patients with venous thrombosis of the proximal limb veins (femoral or popliteal vein) will be investigated with ultrasound agent in supine position. 5 ml of the contrast agent sulfur hexafluoride is given intravenously into a vein of the dorsal foot. The measurements are done in a defined area, where the thrombus is fully occluding in color Doppler investigation. The regions of interest will be the vessel walls and the centre of the thrombus in cross section view. The signal intensities are measured at baseline and peak (in decibel) in the centre and in the peripheral part of the vein. 20 patients with acute deep venous thrombosis will be included in this pilot study and investigated at baseline, after 3 weeks and 3 months. Previously (before contrast agent application), the veins are investigated with color - and power Doppler to test visibility in comparison to the contrast agent investigation.
Laparoscopic inguinal hernia repair (LIHR) has got comparable results in comparison to open hernia repair (OHR). Many studies have shown that LIHR gives similar results in terms of recurrence as compared with OHR but with the added advantage of less chances of post operative, pain, wound infection and early return to activity. LIHR was started using the transabdominal preperitoneal (TAPP) approach. Another technique of LIHR that has evolved is totally extra peritoneal (TEP) repair. There is only one study of 52 patients comparing TAPP with TEP repair and thus there is insufficient information as to which of the 2 techniques is better. Therefore, we have designed the present study to compare the transabdominal preperitoneal (TAPP) technique with totally extra peritoneal (TEP) technique of laparoscopic inguinal hernia repair. The advantages of TEP may include - no breach of peritoneum so less risk of bowel injury and post-operative adhesions. We will be using a modified technique of TEP repair where we will not use tacker to fix the mesh to reduce the cost of the procedure. On the other hand, TAPP is easy to perform and probably better for irreducible hernia. There is no such comparative study reported in the literature. We have been performing both TAPP and TEP procedures for hernia repair regularly in the department. RESEARCH HYPOTHESIS: TEP repair of inguinal hernia is better than TAPP repair in terms of reduced cost and avoidance of peritoneal incision. OBJECTIVE: To compare the Transabdominal preperitoneal (TAPP) vs. Totally extra peritoneal (TEP) techniques of laparoscopic inguinal hernia repair.
This prospective randomized controlled study will determine the efficacy of continuous local anesthesia at decreasing pain scores compared to patient controlled analgesia for pelvic organ prolapse procedures including posterior colporrhaphy and sacrospinous ligament fixation.
The purpose of this study is to determine how parents of children with cancer rate a parent-delivered massage therapy educational program for usability and satisfaction, and if massage therapy, provided by parents to their child with cancer, reduce symptoms of anxiety and depression in the child, and parenting stress in the parent.
The purpose of this study is to evaluate the efficacy of rosiglitazone alone compared with rosiglitazone plus metformin or rosiglitazone plus losartan in the treatment of biopsy proven nonalcoholic steatohepatitis (NASH). This study was designed to answer the question: are there differences in the efficacy (as measured by histopathology and insulin resistance) of three different therapeutic modalities used to treat NASH?
Topiramate (TPM) is an antiepileptic drug with a unique mode of action that is often useful in patients refractory to other drugs. However its use is restricted by the high incidence of cognitive adverse drug reactions (ADRs) that are associated with TPM exposure. TPM has been shown to cause particular cognitive ADRs, characterized by verbal fluency, attention, working memory and language deficits, at a much higher rate than other antiepileptic drugs. There do not appear to be obvious differences between patients that do or do not experience cognitive ADRs when on TPM (e.g. age, sex, concomitant medications, diagnosis), which suggests a genetic contributor.
