The purpose of this study is to collect breath samples from healthy and cancer sick patients. The breath, collected to special bags, will be transferred to laboratories in the Technion and analyzed using an electronic nose system developed in Hossam Haick's labs (Chemical Engineering, Technion). The hypothesis is that based on the analysis of the chemical bio-markers present in the exhaled breath, cancer states can be distinguished from healthy subjects or before and after treatment, allowing a technique for diagnosis of cancer and/or cancer treatment.
The current treatment guidelines of hepatocellular carcinoma (HCC) of the American and European Associations for the Study of Liver Disease are based on the Barcelona-Clinic-Liver-Cancer classification (BCLC), which does not recommend surgery in patients with large, multinodular and macrovascular invasive disease. The aim of this study was to investigate the role of hepatic resection in a large retrospective multicentric cohort of patients resected for HCC regardless of the BCLC indications.
Breast reconstruction with a pedicled myocutaneous latissimus dorsi (LD) flap is a widely used reconstruction method. It is controversial if surgical denervation by transecting the thoracodorsal nerve should be performed or not. It is assumed that after denervation the latissimus dorsi muscle will significantly atrophy and lose volume. On the other hand discomforting signs and symptoms from muscle contraction are believed to be prevented if flap is denervated. The aim of the study was prospectively evaluate the influence of LD-flap innervation on the functional and aesthetic outcome of delayed breast reconstruction, and to compare the change in muscle structure in breast MRI and histopathology.
To investigate that the efficacy of 3% DE-089 ophthalmic solution (one drop at a time, 6 times daily, 4 weeks topical administration), in comparison to 0.1% sodium hyaluronate ophthalmic solution (0.1% HA) (one drop at a time, 6 times daily, 4 weeks topical administration), is at least non-inferior in the change in fluorescein staining score, and is superior in the change in Rose bengal score, in a multicenter, double-masked, parallel-group comparison study. Safety profile will likewise be compared.
The aim of this study is to assess the effect of preoperatively administered intra venous magnesium sulfate in attenuating pressure response to laryngoscopy and endotracheal intubation in adult patients scheduled for elective non ocular surgery
AASD is a new dialysis technique based on the use of a mathematical model of intradialytic solutes and fluid kinetic, for the automatic elaboration of dialysate sodium and ultrafiltration rate profile. The aim of dialysate sodium and ultrafiltration rate profile is to obtain the higher stabilization of intradialytic extra cellular compartment, in consideration of end session targets: body weight and final patient's natremia. In this multicenter prospective controlled randomized trial the primary end-point is the clinical efficiency validation of AASD on intradialytic hypotension but also on thirst, cramps, headache, nausea, vomiting, hypotensive events observed in basal treatment (HD or HDF).
Background: Biofeedback techniques have demonstrated their uselfulness in the treatment of maculopathies. We wanted to evaluate the efficacy of visual rehabilitation by means of two different types of biofeedback techniques in patients with age related macular degeneration (AMD). Methods: 30 patients bilaterally affected by AMD were enrolled with a mean age of 76,38±8,77 yrs. Patients were randomly divided in two groups: Group A was treated with an acoustic biofeedback, Group B with luminous biofeedback of a black and white checkerboard flickering during the examination. All patients underwent a complete ophthalmological examination. Rehabilitation consisted in 12 training sessions of 10 minutes for each eye performed once a week for both groups. Statistical analysis was performed using t- test. P values less than 0.05 were considered statistically significant. Results: Group A: visual acuity at the end of rehabilitation had improved, but this result was not statistically significant (p=0.054), reading speed showed a significant statistical improvement (p=0.031), as well as the fixation stability (p=0.0023) and single point mean retinal sensitivity value (p=0.044). Group B: visual acuity improvement at the end of rehabilitation was statistically significant (p=0.048), reading speed showed a statistically significant improvement (p=0.024), as well as fixation stability (p=0.0012) and mean single point retinal sensitivity value (p=0.027). Final results for both groups were compared and patients in group B showed results which were statistically more significant. Conclusion: A contrast rich flickering biofeedback stimulus showed a statistically significant improvement in training the patients to modify their preferred retinal locus (PRL) in comparison to acoustic biofeedback. It is possible that increased involvement of the various retinal cell populations with visual stimuli create more efficient ganglion cell response that better utilize the residual retinal function.
The Visual Pathfinder (LACE inc.) offers a non- invasive, patient- centered visual rehabilitation system based on an acoustic biofeedback. The investigators wanted to evaluate its usefulness in the improvement of visual function in visually impaired patients with high myopia.
The purpose of the study is to assess the effect of a single dose of NI-0801 on the severity of nickel-induced allergic contact dermatitis.
Tuebingen High Altitude Ophthalmology Study to investigate the effects of high altitude on retinal structure and function as well as anterior chamber in regard to acute mountain sickness.
