Filter by:Minimally invasive techniques have been widely used routinely and reliably in the treatment of pilonidal sinus. In some of these methods, the cavity of sinus remains in the patient; this condition caused us to question the necessity of pathological examination. Except for prolonged duration of disease, elderly age, macroscopic suspicion, and recurrence; We think that routine pathological examination of the pilonidal sinus is unnecessary.
Causes such as long-term stones and polyp are thought to play a role in the etiology of gallbladder cancer. The routine histopathological examination provides the detection of incidental gallbladder cancers. It should be remembered that acute or chronic cholecystitis accompanied by the thicked wall and a prolonged history of gallstones may be the cause of malignancy, especially in elderly patients.
The objective of this study is to evaluate the repeatability and reproducibility of detection of histological features using whole slide imaging
The primary objective of this study is to evaluate the safety and accuracy of the Hamamatsu WSI compared to those of the reference method (conventional light microscope (Glass)) under clinical use conditions as an aid for pathologists to view, review and diagnose digital images of surgical pathology slides. The primary endpoint is the indicator of major discordance in primary diagnosis between ground truth case diagnosis and case diagnosis by each modality, WSI and Glass, separately.
The aim of the study is to evaluate the relationship between the vitamin D replacement and pathological response in patients undergoing neoadjuvant therapy according to different molecular sub types. Because of no study evaluating pathological response to neoadjuvant therapy with vitamin D replacement in patients with breast cancer.
The investigators aim to investigate the utility of radiomics to differentiate malignant nodules from benign nodules and invasive adenocarcinoma from non-invasive adenocarcinoma.
The aim of this study is to establish large tissue sections for 10 kinds of tumors. in order to observe the tumor landscape on microscope. The tumors including esophageal carcinoma,gastric carcinoma,hepatocellular carcinoma etc.200 cases of each tumor will be compared by traditional sample method and landscape sample method to testify the clinical value and significance of tumor landscape pathological diagnosis .
To set up a Cooperative Network by enrolling 5000 patients with Adenomyosis(AM) from multiple centers.Based on the Network platform and Database,the investigators try to explore the diagnostic strategies for AM and carry out epidemiological survey on the semeiology of AM.In addiction，the investigators expect to conduct research on the effect and the follow-up fertility outcomes of different medical or surgical treatment, the etiology of AM and endometriosis,the perspective investigation of the malignant transformation of AM ;the high-risk factors of AM,and finally propel the formation of Expert Consensus and Clinical Guidelines about AM which suitable to chinese conditions.
The purpose of this study is to examine deficits in activation and motor patterns, as well as central drive in patients with rotator cuff tendinopathy. There are three specific aims: (1) determine the effect of acute pain relief on rotator cuff muscle activation in patients with rotator cuff tendinopathy, (2) determine the effect of exercise on rotator cuff muscle activation in patients with rotator cuff tendinopathy, and (3) compare rotator cuff muscle activation between patients with rotator cuff tendinopathy and healthy controls.
The investigators hypothesise that simulation-based training will have initial educational benefits and in coherence with the traditional apprenticeship model will heighten the educational end-level: That training on the simulator before clinical education will prepare the trainee for practice and thereby support more effective learning.
