Evaluation of the Diagnostic Performance of Electrical Impedance Tomography to Detect Situations...

Respiratory Distress Syndrome

Acute respiratory distress syndrome remains a serious condition, with a mortality rate of between 30 and 50%. The use of mechanical ventilation with small tidal volumes, and by limiting the plateau pressure in the respiratory tract below 30 cm H2O has been shown to reduce mortality by approximately 10%, probably by reducing pulmonary hyperinflation and pulmonary lesions induced by mechanical ventilation. It is therefore now established that the respirator settings influence patient prognosis. However, around 30% of patients with ARDS ventilated with these settings supposedly protective continue to present signs of pulmonary hyperinflation on tomodensitometry, suggesting an additional reduction in the tidal volume could be required in certain patients. Electrical impedance tomography (EIT) is a new imaging technique that gathers functional pulmonary information at bedside. This technique also allows a regional analysis, allowing the complexity of the spatial distribution of ARDS pulmonary lesions to be understood. The hypothesis is that EIT is a reliable method to detect at-risk situations of lesions induced by mechanical ventilation among patients with ARDS.

Evaluation of the Free α-hemoglobin Pool in the Red Blood Cells : Prognostic Marker and Severity...

Thalassemic Syndromes

Our project aims to assess and validate an innovative prognostic and diagnostic test in order to i) define a severity index of the β-thalassemia according to the free α-Hb pool for a better management of the patient; ii) differentiate the α-thalassemia and β-thalassemia and iii) follow the evolution of this pool in response to treatment of patients. In the future, this prognostic test based on the measurement of free α-Hb pool may be suitable for routine laboratory practice. To carry out this project, cohort of 85 thalassemic patients and a group of 50 healthy volunteers have been recruited.

High Definition White-Light Colonoscopy vs. Chromoendoscopy for Surveillance of Lynch Syndrome....

Lynch Syndrome

Adenomas in Lynch syndrome have an accelerated progression to colorectal cancer (CRC) which might occur despite a regular follow-up. Despite low evidence, high-definition technology (HD) and indigo-carmine chromoendoscopy (CE) are recommended for surveillance in Lynch syndrome.The investigators will conduct a prospective multicenter randomized non-inferiority study. The principal aim is to compare the adenoma detection rate with WLE vs CE. Our hypothesis is that HD-white-light endoscopy (WLE) is not inferior to CE. Therefore - under expert hands - HD-CE does not add any significant advantage over HD-WLE on adenoma detection rate in patients with Lynch syndrome.

Myalgic Encephalomyelitis Chronic Fatigue at the National Institutes of Health

Chronic Fatigue Syndrome

Background: Post-Infectious Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (PI-ME/CFS) refers to long-lasting and disabling fatigue or malaise, inability to recover after exercise, and physical and emotional discomfort that may occur after a person has an infection. Researchers want to learn more about its causes. Objective: To learn more about PI-ME/CFS. Eligibility: Adults ages 18-60 years who have finished at least 7th grade education and either: have ME/CFS that started after an infection OR had Lyme disease, were treated, and returned to normal health OR are healthy volunteers Design: Participants will initially have a 2-5 day inpatient visit at the National Institutes of Health Clinical Center in Bethesda. During the visit, participants will have: Medical history Physical exam Intravenous (IV) line. A thin plastic tube is inserted into a vein. Blood and urine collected Magnetic resonance imaging (MRI). Participants will lie in a machine that takes pictures of their brain. They may get a dye through their IV. Grip strength tested Saliva, cheek swab, and stool collected Tilt table test with measures of body functions such as sweating and breathing, blood pressure, and heart rate and blood and urine sample collection Collection of blood cells. Participants can choose to have the blood drawn through the IV or through a machine that filters blood cells and returns the liquid blood back into the participant s vein. Lumbar puncture. Fluid will be removed by placement of a needle between the back bones. Heart monitoring Sleep study for participants with PI ME/CFS Questions about the participant s life and how they are feeling Questions from a neuropsychologist Questions from an occupational therapist for participants with PI ME/CFS Questinos from a nutritionist After the initial visit participants will return home. Participants evaluated for PI-ME/CFS during the first visit will have their information reviewed by an adjudication panel of experts in the diagnosis and care of ME/CFS to determine if they are eligible to participate in the second study visit. Eligible participants will be invited back for a second study visit. If a participant was taking certain medications during the first visit, they may be asked to taper off of them prior to the second visit and report any problems. They will also receive an activity monitor, fatigue diary, and nutrition log to use for at least one week prior to their second visit. Participants who are eligible will return for a 5-10 day inpatient hospital visit at the National Institutes of Health Clinical Center. During the visit, participants will undergo measurements before and up to 96 hours after performing a stationary bike exercise test. The purpose of the exercise test is to provoke ME/CFS symptoms (post-exertional malaise). Tests will be performed before and after exercise testing. These include: Sleeping in a room that measures how the body uses energy with EEG monitoring Eating a controlled diet Performing vigorous exercise for 10-15 minutes Questions about how participants are feeling Questions about what participants usually eat Samples of saliva, blood, urine and stool Wearing an activity monitor Having an Xray that measures body composition Thinking and memory tests Heart monitoring Transcranial magnetic stimulation. A brief electrical current to the scalp creates a magnetic pulse that affects brain activity. Magnetic resonance imaging (MRI). Participants will lie in a machine that takes pictures of their brain. They will do thinking and exercise tasks during the MRI. Lumbar puncture. Fluid will be removed by placement of a needle between the back bones.

The Effect of Anterior Corneal Incisions on Intraoperative Floppy Iris Syndrome (IFIS) Incidence...

Intraoperative Floppy Iris Syndrome

Intraoperative Floppy Iris Syndrome (IFIS) may occur during cataract surgeries in patients treated with alpha 1 blockers. IFIS related to alpha 1 blocker Tamsulosin (used for prostate hypertrophy) was reported in 50-90% of patients. IFIS during surgery make the surgery more difficult and raise complication rate. Using anterior corneal incisions was reported briefly in literature as a prophylactic means but was not studied prospectively. we believe (according to our clinical experience) that these anterior incisions do help to reduce the incidence and severity of IFIS signs and complications rate during surgeries.

Adaptive Support Ventilation in Acute Respiratory Distress Syndrome (ARDS)

RespirationArtificial2 more

Prospective randomized controlled trial to be conducted in the Respiratory Intensive Care Unit (RICU) of Post Graduate Institute of Medical Education And Research (PGIMER),Chandigarh. The study is approved by the Institute Ethics committee. In view of lack of previous outcome data in such patients, all patients requiring RICU admission for acute respiratory distress syndrome(ARDS) between January 2010 and June 2011 are being enrolled in this pilot study. The patients meeting the aforementioned criteria will randomly assigned to ventilation with assist control mode ventilation (ACMV group) as per the ARDSnet strategy or adaptive support ventilation (ASV group). Being the first RCT of its type, patients will be first stabilized on ACMV for 1 hour to determine the adequate minute ventilation. The randomization sequence will be computer generated. The assignments will placed in sealed opaque envelopes and each patient's assignment was made on admission to the RICU by the attending physician. Blinding of treatment is not possible. All patients will be ventilated only by Galileo Gold ventilators (Hamilton medical systems, Bonaduz, Switzerland). Patients randomized to the ACMV group will be ventilated according to low tidal volume strategy of 6ml/kg with Fio2/PEEP as per ARDSnet table to achieve a saturation between 88-95% with the lowest possible Fio2 to maintain plateau pressures < 30 cms H2o and PH > 7.3 with option to reduce tidal volume to 4 ml/kg and increase respiratory rate to 35/ min to achieve the above said goals11.These patients will be weaned as per standard protocol of spontaneous breathing trial of 30 minutes once they are recognized eligible as per statement of the sixth International consensus conference on weaning.

Myelodysplastic SyndromeChronic Myelomonocytic Leukemia

5-azacytidine treatment prolongs survival in patients with myelodysplastic syndrome (MDS), but does not cure the disease. Allogeneic stem cell transplantation is a curative treatment option but is associated with a high risk treatment-related morbidity and mortality. In the current trial allogeneic stem cell transplantation will be compared to 5-azacytidine only treatment according to donor availability in elderly patients with MDS (55-70 years).
