Filter by:Patients with allergic rhinitis frequently present exacerbation of the atopic symptoms during viral infections of the upper respiratory tract. Also, allergic rhinitis makes the mucosa more reactive to infectious agents and potentiates mucus production. The combination of dexchlorpheniramine, pseudoephedrine and guaifenesin elicits antihistaminic, decongestant and expectorant effects. The study hypothesizes is that this product is superior to dexchlorpheniramine alone in the relief of allergic symptoms and in promoting mucus elimination in atopic patients with viral infections of the upper respiratory tract.
Sedentary lifestyle and poor dietary choices are leading to a weight gain epidemic and increasing the risk for developing nonalcoholic fatty liver disease (NAFLD). The strong relationship between insulin resistance and NAFLD suggests that adding Vitamin D TO insulin sensitizing therapies such as Galvus (vitagliptin) might be beneficial in the prevention or improvement in NAFLD. Considering the close relationship between NAFLD and T2DM and lipid metabolism, we assume that adding vitamin D to Galvus, may be effective for NAFLD by improving lipid metabolism and by improving type 2 diabetes mellitus (T2DM).
To determine the possible association of prothrombin fragments 1+2 elevation with incidents of pulmonary embolism in patients with COPD exacerbation.
Transient left ventricular ballooning syndrome (TLVBS) is a cardiac syndrome that is characterised by acute but transient left ventricular (LV) dysfunction. Since the syndrome clearly is not a rare phenomenon and since prognosis is not as benign as originally thought, there is a need for further research into the etiology and pathophysiology of TLVBS. Therefore the investigators aim to study the microvascular and endothelial function in their population of TLVBS patients.
Despite aggressive treatment, patients with heart failure have a poor prognosis. Docosahexaenoic acid (DHA), an omega-3 polyunsaturated fatty acids found in fish oils, may prevent the progressions of heart failure through mechanisms that are not addressed with current drugs. The omega-3 polyunsaturated fatty acids Docosahexaenoic Acid (DHA) and Eicosapentaenoic acid (EPA) favorably impact mitochondrial dysfunction and chronic inflammation in heart failure (HF). Treatment with DHA-t-EPA alters cardiac phospholipid composition by decreasing arachidonic acid (a pro-inflammatory fatty acid) and increasing DHA and the mitochondrial phospholipid cardiolipin, with is associated with improved Left Ventricular (LV) function. Fish oil supplements contain a mix of DHA and EPA, however we postulate that DHA is superior to EPA in improving mitochondrial function and suppressing inflammation, and thus DHA should be used to treat HF. Cardiac phospholipid fatty acid composition (i.e. DHA, EPA, and arachidonic acid) and cardiolipin (CL) content will be measured in biopsies from stable heart transplantation patients that are obtained as part of standard clinical care in heart transplant patients before and after treatment with DHA alone or DHA+EPA. We will compare cardiac phospholipid composition from biopsies obtained at study entry and at 6 months follow-up (allowable range +/- two months, depending on patients' clinical conditions).
Fluid leak around the cuff is minimized when the endotracheal tube size is small relative to the size of the trachea. In the current study, the investigators assess the influence of different HVLP endotracheal tube size on fluid leakage around the cuff in a benchtop model and in anesthetized patients.
As known from several observational and retrospective endoscopic studies the prevalence of gastric inlet patches (GIPs) of the cervical esophagus is estimated between 1-10%. In most cases GIPs are found within endoscopy as an incident finding, since in most cases they are harmless and do not cause any symptoms. None the less several data exist where an association between GIPs and globus sensations is discussed. Case reports even refer to bleeding complications and moreover to malignant transformations of GIPs. As a result of the assumed association of GIPs and globus sensations we performed a pilot trial. Here we included 10 patients with globus and GIPs and were able to demonstrate a significant symptom relief after ablation of the GIP (Meining et al, Endoscopy 2006). To exclude a potential placebo-effect we concluded a multicenter and sham controlled trial where we imposingly were able to prove the symptom relief after ablation of the GIPs (Bajbouj et al, Gastroenterology 2009). All patients, who are scheduled for esophagogastroduodenoscopy (EGD) in any of the above mentioned endoscopical departments are routinely standardized asked whether they have any hints suggestive for globus sensations (modified globus-questionnaire from Deary et al., J Psychosom Res 1995). Concurrently it is noted, whether the patients have endoscopical detected GIP. All GIPs are biopsied and examined in one institute. Together with anamnestic data (age, gender) a talley sheet gives a survey of all relevant information to prove or disprove following hypotheses. Study hypotheses: 1. The presence of GIPs is associated with globus sensations. In other words: Do patients with globus sensations significantly more often have GIPs? 2. GIPs are not congenital, they arise in the course of the time and become symptomatic. In other words: Do GIPs significantly occur in more elderly people? 3. The more increased the GIPs diameter is the more likely globus sensations are present? In other words: Do huge GIPs cause significantly more often symptoms than small ones? 4. The more mucus-producing mucosa is histologically proven the more likely globus sensations are present? In other words: Do we find more cardiac mucosa in patients with symptoms than fundus mucosa?
The relationship between WM lesions (WM) and Postural Instability Gait Disorders (PIGD-PD)in Parkinson's disease patients is largely unknown. We hypothesize that sub-clinical WM pathology may be a major contributing factor to PIGD-PD. We will compare two groups of patients with Parkinson's disease (PD): those with PIGD and patients with dominant tremor (n=120)to assess the role of brain WM changes.
Cholangiocarcinoma (CCA), cancer of the bile duct, is the first cause of cancer death of the people in the northeast of Thailand. The incidence of CCA in this region is highest not only in the country but in the world. CCA is a slow growing but highly metastatic tumor. At present, there is no standard chemotherapy or effective treatment for CCA. Most of the patients have short survival after diagnosis. Strong evidences from in vitro, animal and clinical studies indicate that vitamin D can prevent and control growth of cancer. Our preclinical studies in CCA cell lines, animal and patient tissue culture indicate that vitamin D effectively reduce growth of CCA. Supplementation of vitamin D to chemotherapeutic drugs enhance drug toxicity and better response. At present, there are several clinical trials in USA on supplementation of vitamin D or its analogs to cancer patients. The side effect or toxicity of using vitamin D supplementation is low, some patients had stable disease and some had good response. The current study is set up a clinical trial phase II of vitamin D (calcitriol) in combination with 5-fluorouracil, Mitomycin C and Leucovorin in an open label-non-randomized study to evaluate the tumor response in patients with advanced intrahepatic cholangiocarcinoma. This study will provide an alternative/effective chemotherapy treatment for CCA patients. Better survival and improved quality of life are also expected.
