Filter by:A positive Anti-Neutrophil Cytoplasm Antibody (ANCA) test administered to patients with a high probability for vasculitis has high sensitivity and specificity for vasculitis. A positive ANCA test result in those patients who do not have a high probability for vasculitis requires extensive follow-up because those patients eventually present with malignancy or other inflammatory diseases. The investigators wish to investigate the correlation between the differing levels of positive ANCA tests and their relationship to vasculitis, malignancy and inflammatory diseases.
Patients with extensive-stage small cell lung cancer receive six cycles of chemotherapy(etoposide plus platinum) as first-line treatment,who achieve Complete Response(CR)/Partial Response(PR) will accept small doses of etoposide as maintenance treatment. The objective of this study is to evaluate the progression free survival,overall survival,objective response rate,disease control rate and safety of etoposide as maintenance therapy. Based on previous studies on maintenance therapy in small cell lung cancer,the hypothesis of this study is maintenance therapy using etoposide may improve progression free survival,overall survival for selected patients. The investigators will use the peripheral blood to assess circulating tumor cell and cell-free DNA,which may help us to screen a subgroup of patients with better response to etoposide maintenance therapy.
The Objective of This Study is Evaluating the Effect of oral β- glucan Supplement on Anthropometric Measurements, Appetite, Insulin Resistance, Liver echogenicity and Enzymes in Non Alcoholic Fatty Liver Patients Treating with Hypocaloric Diet and Vitamin E.
Hypotension after spinal anesthesia for cesarean section is one of the most common perioperative issue, with an incidence up to 83%.Hypotension is mainly induced by the associated sympathetic blockade, with a drop of peripheral vascular resistance in the lower extremities and an increase in venous capacitance. Hypotension is a distress for both anesthesiologists and obstetricians as it endangers parturient's hemodynamics and compromises the uteroplacental blood flow. In clinical practice, there are several ways to treat hypotension after spinal anesthesia such as preloading with intravenous fluids and administrating ephedrine. Normotensive maternal blood pressure does neither guarantee the well-being of the fetus nor ensure the tissue perfusion of the parturient. Based on the anatomy and physiology basis, we hypothesize that uterine perfusion under spinal anesthesia would correlate with the perfusion of the lower extremities. To measure the perfusion of the lower extremities, we use a relative new tool, the non-invasive transcutaneous near infrared spectroscopy.
Breast lesions are a common condition, diagnosed by imaging and palpation. In order to reduce the number of biopsies performed to the definitive diagnosis of a breast lesion, an imaging method with a high degree of accuracy is needed. Ultrasound imaging with microbubbles contrast media allows the diagnosis of vascularization of the lesion, according to timing. Our hypothesis is that a highly vascularized lesion that enhances in an early timing is most likely to represent a malignant lesion and thus, deserves biopsy for a definitive diagnosis. Females over 18 years age, with a focal lesion in breast will be suitable to perform this examination.
Lymphedema is the result of accumulation of fluid and other elements in tissue spaces because of an imbalance between the production of fluid interstitial and transport. Lymphedema can cause significant physical and psychological morbidity. Prevalence of lymphedema in patients after breast cancer surgery is 12-60% and the incidence is 12-26%.Psychological and social consequences of secondary lymphedema related breast cancer have been little recognized and documented. Although, it have performed many studies related secondary lymphedema it not found sufficient evidence in the literature to suggest the most effective treatment. There is some evidence suggesting that compression therapy and manual lymphatic drainage can improve lymphedema but more studies are needed. The aim of this research is to to evaluate the clinical effect of multimodal treatment (compression bandaging and manual lymph drainage) versus applying manual lymphatic drainage in women with arm lymphedema after breast cancer surgery.
Developmental dislocation of the hip is a common disease in children, and its incidence in China is about 9 ‰.The pathological changes of it is complex. The reluxation , subluxation and residual deformity and other complications are relatively common after treatment. The X-ray appears great acetabular index and wide medial gap , small central-edge angle. As there is no effective methods for treating such complications , investigators conducted this trial to find and prove optimal intervention time and treatment programs.
The neuropsychological profiles of children treated with standard CBT for OCD are evaluated.
Eye surgeries are traditionally performed under local anaesthesia with a peribulbar block. This is a blind technique where local anaesthetic is injected into the back of the eye to make the eye numb and motionless for surgery. This is a blind injection and can be associated with complications such as bleeding, rupture of eye globe, blindness, increasing the pressure of the eye etc. It also has a high failure rate resulting in need for additional injections, further exposing the patient to possible complications. The investigators propose to perform the peribulbar block with ultrasound to guide the block needle placement and injection. The investigators hypothesize that ultrasound guided peribulbar blocks would have higher success rate (less need for additional injections) and that the total amount of local anaesthetics used would be decreased.
Hysterectomy is one of the most performed surgery in gynecologic surgery. Actually, 70 000 hysterectomies are performed each year in France. Laparoscopic surgery is in progression. The percentage of hysterectomies performed laparoscopically is increasing. The advantage of laparoscopy include fewer infections, less operative pain, faster recovery time and shorter hospital stay. In France, the average of hospital stay after laparoscopic hysterectomy reduced to 3-4 days. The study hypothesis is that a shorter postoperative stay does not decrease the quality of life of the patients. This study will compare the evolution of quality of life (with a questionnaire concerning measuring health related quality of life the Euroqol EQ-5D) of patients discharged after 3 days hospital stay to patients discharged the first day after a laparoscopic hysterectomy.
