The aim of the study is to investigate the influence benign non-toxic goitre and the surgical treatment hereof on the voice function before and 6 months following surgery.

The hip or knee is a validated treatment of end-stage osteoarthritis, and these interventions commonly make a significant improvement in the quality of life of patients. Infection can occur in 1-5% of cases. Diagnosis is often difficult, but the knowledge of infected or not infected character directly influences the surgical conduct. It is therefore recommended that the positive or negative diagnosis is made in the most reliable way possible, but no single element only allows a low diagnosis. The concomitant use of several clinical, radiological and aggregated into a composite score history could help facilitate this preoperative approach during reoperation on prosthetic joint

Background and study aims : The investigators conducted this study to compare the movement of extraocular muscle after two types of recession surgery with non-invasive tool called AS-OCT. Who can participate? patients who will undergo two types (conventional method and hang-back method) of typical bilateral lateral rectus recession surgery for correcting intermittent exotropia What does the study involve? Volunteers will attend a clinic for four visits over three months. They will undergo AS-OCT at every visits during follow up period. AS-OCT is non-invasive test to evaluate operation site. The test only requires their cooperation when they undergo AS-OCT. What are the possible benefits and risks of participating? This is non-invasive test for your postoperative follow up. Therefore, there will be no risks about this test. Where is the study run from? Samsung Medical Center When is the study starting and how long is it expected to run for? From April 2015 to Dec 2015

The purpose of this study is to determine clinical factors affecting quality indicators of colonoscopy including adenoma detection rate, and whether quality of colonoscopy could be elevated by improving related factors.

Photoplethismography will be measured and compared in newborns suffering from patent ductus arteriosus and normal controls.

Prostate cancer (PC) is the most common non-skin tumor in men and the second leading cause of death from cancer in Brazil. It accounts for 13.8% of deaths from cancer in males, similar to what happens with breast cancer in females, corresponding to 15.8% of cancer deaths in women. Mobile applications, software developed for smartphones and tablets used for many different purposes (games, communication, entertainment etc) have become important tools of mHealth (Mobile Health in Portuguese - mobile health) as they allow remote support to patients or self-promotion of health care. It has been used globally to assist in the treatment and control of various diseases such as diabetes, physical inactivity, and many others. In oncology there are several applications developed to assist in the monitoring and treatment of various cancers such as gastric and breast cancer. So far it has not developed an application for follow-up of patients with PC, to capture data on satisfaction of post-treatment patient regarding the comorbidity of surgery, and also loyalty and adherence of patients to follow-up in offices allowing a possible intervention it is done at the right time. Nor was made compared to assess whether there is benefit in using this application. Thus, the objective of this work is to develop an application for smartphones facing the postoperative follow-up of patients undergoing robotic radical prostatectomy and compare adherence to treatment compared to accompanied by traditional way patient. In addition, we will evaluate the progress of the IPSS, ICIQ and IIEF-5 compared to preoperatively in patients undergoing prostatectomy robotic radical.

The aim of this study is to investigate whether there is a correlation between anti-Müllerian hormone during long-term use of combined oral contraceptives and the recovery time before recovered menstrual cycle after discontinuation of oral contraceptives.

Objective: To focus the high dose radiation to the gross tumor in the prostate while maintaining adequate dose for control of microscopic disease elsewhere in the prostate. In order to test the incorporation of the robust MRI and TRUS fusion algorithm in the clinical setting the investigators planned a study of Focused therapy with a primary endpoint of accurate localization of the high risk region. This is a pilot study of dose painted permanent I-125 seed implant to verify absence of tumor cells outside a high risk region using multi-parametric MRI and deformable TRUS registration. The high risk region will be dose painted to 160 Gy and the rest of the prostate will receive the normal prescription dose.

Histological grade of hepatocellular carcinoma (HCC) is an important prognostic factor affecting patient survival. It has been divided into four grades from I to IV on the basis of histological differentiation. Grade I is the best differentiated consisting of small tumor cells arranged in thin trabeculae. Cells with higher grade are larger and less differentiated with hyperchromatic nuclei and loss of trabecular pattern. Ultrasound is an imaging modality frequently used to evaluate liver tumors because of its convenience, real-time, less expensive and no radiation exposure. However, ultrasonographic evaluation by conventional B-mode image is semi quantitative and subjective. It still cannot replace liver biopsy for the evaluation of HCC. This study is aimed to quantify the image characters of B-mode image and the scatterer properties using Nakagami distribution. Nakagami parameter is a general model to describe the distribution of scatterers. Therefore, the investigators hypothesized that Nakagami parameter may also reflect the histological changes in different grades of HCC. In this study, the resected HCC tumor samples will be collected from the participants who are going to receive surgical resection, and the tumor US images and Nakagami values will be obtained via the single-element ultrasound system. The correlation between the ultrasound backscatter parameter and the differentiation grade will be analyzed.

Longitudinal descriptive study of a cohort of twenty brain-damaged patients for a two years period.
