Filter by:The purpose of this study is to determine clinical impact of EUS-guided microbiopsy procedure and supplementary molecular analyses compared to standard diagnostic workup of pancreatic cysts. The hypothesis is that a combination of previously mentioned modalities may change the management of some pancreatic cystic lesions, increase the diagnostic accuracy and optimize the discrimination between high- and low-risk pancreatic cysts.
More than 200,000 new cases of renal cancer are diagnosed in the world each year, with more than 63,000 new cases in Europe alone. Of those, renal cell carcinoma (RCC) is the most common type in adults, making up more than 90% of the cases. Deciding on the benign or malignant nature of some RCC on the basis of medical images (CT, MRI, US) is an issue, which often leads to unnecessary surgery, morbidity and costs. A categorization for renal cysts was introduced in the late 1980s known as the Bosniak classification. The Bosniak classification system classifies them into groups that are benign (I and II) and those that need surgical resection (III and IV), based on specific imaging features. However, defining the malignancy of category III lesions still remains a challenge. Though Bosniak classification for renal cysts is used worldwide and underwent a number of modifications, Bosniak III cysts still have almost a 1:1 chance of being malignant. So the problem is that approximately half of the Bosniak category III cystic lesions prove to be benign after surgery. The proposed project aims to develop a quantitative image analysis (QIA) based multifactorial decision support system (mDSS) capable of classifying renal cysts with high accuracy into benign or malignant status, thus reducing the amount of unnecessary surgeries performed. Using standard-of-care CT images and clinical parameters, the customized DSS will then guide experts in planning a safe and effective diagnostic and treatment strategy for all RCC patients.
The aim of this study is to determine whether the use of progesterone only pills has a beneficial effect over the expectant management of functional ovarian cyst or not , through a sample of female patients within the reproductive years
This prospective study will primarily aim to determine what monitoring is required of ovarian cysts when they are diagnosed in pregnancy, as well as what intervention, if any, is necessary. It also aims to identify the prevalence of ovarian cysts in pregnancy and the nature of these cysts, as well as their natural history throughout pregnancy.
The efficacy of traditional therapeutic approaches for aneurysmal bone cysts (ABC), such as surgery, embolization, sclerotherapy and radiotherapy, are often compromised for lesions in axial skeletons and adolescents complicated with pathological fracture. Therefore, denosumab, a new drug that has been successfully used in giant cell tumor of bone but has seldom used in ABC, was used to treat ABC in this trial.
Women will be managed by either of the two modalities and will be followed up by transvaginal ultrasound monthly for three successive months to evaluate the size and location of the functional ovarian cyst (follicular), to compare the effect of different modalities of management whether remission, regression, progression or persistence of functional ovarian cyst. The women will be assigned randomly to either study group to take oral contraceptive pills or to control group to take placebo. The 2 groups will be treated and followed up equally. Oral contraceptive pills will be given to the study group as follow: The women will receive one package of oral contraception (Cilest containing norgestimate 250 microgram + ethinyl estradiol 35 microgram) and will be counseled about how to take oral contraception and informed of possible side effects. They also will receive a diary card for recording oral contraception intake to be returned to the physician on the next period. An appointment for the women in this group will be scheduled at one month of treatment for the second ultra-sonography. If the ovarian cyst does not show remission, the women will continue the same treatment and will follow up in another month by transvaginal ultra-sound. If the ovarian cyst still persists or progresses at the second month, the women will be followed up for third month. All results of the two groups will be compared. Data will be collected, tabulated according to the standard statistical method.
The main objective of the study is to compare the diagnostic accuracy of intra-cystic fluid DNA molecular analysis to standard diagnostics. The secondary objective of the study is to evaluate the feasibility of intra-cystic fluid DNA molecular analysis.
Renal functional reserve may be improved in patients with simple renal cysts after laparoscopic deroofing.
Digital mucous cysts (DMCs) are a benign rubbery cystic lesion which usually involve the dorsal or lateral side of DIP joint (digital interphalangeal joint) or proximal nail fold. The most successful treatment way is surgical management. However, which may cost time, require expertise, may cause infection, prolong wound healing and sometimes may lead to the joint movement limitation. The investigator bring this new technique: percutaneous capsulotomy for digital mucous cysts, which is easy and quick, last but not least, low recurrence rate.
This study evaluates the utility of using cyst fluid glucose levels to diagnose mucinous pancreatic cysts during endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) procedures.
