BACKGROUND AND PURPOSE Recognition of shunted pouches dural arteriovenous fistula allows us to treat the disease effectively by selective embolization of the pouches at first. However, the shunted pouches in transverse-sigmoid sinus dural arteriovenous fistulas have not been well-documented. Our aim was to evaluate the angioarchitecture of transverse-sigmoid sinus dural arteriovenous fistulas, ...

Adult intussusception is rare and most often associated with cancer. We report a case of intussuscepted sigmoid colon into the rectum protruding from the anus of a 47-year-old woman. The cause of the intussusception was sigmoid colon cancer. We removed the intussuscepted part of the sigmoid colon as well as the rectum and regional lymph nodes. The patient recovered uneventfully and there has be...

Mucosa-associated lymphoid tissue (MALT) lymphoma is predominantly found in the stomach. Rarely, it is found in the proximal colon and even less so in the sigmoid colon. We present a rare case of primary sigmoid colon MALT lymphoma in a patient with concomitant Helicobacter pylori and hepatitis C infection. We also review current imaging, staging, and therapeutic modalities. To our knowledge, t...

a 78-year-old woman with a history of colon cancer with metastasis to the liver was presented to our emergency department because of bilateral groin pain and difficulty in walking, which had gradually increased during the previous 5 days. the pain was of sudden onset, radiating to the back, without aggravating or relieving factors. it was associated with constipation, dysuria and vaginal discha...

BACKGROUND AND STUDY AIMS Colorectal endoscopic submucosal dissection (ESD) is associated with significant technical difficulty, long procedure time, and increased risk of complications, especially perforation. This study aimed to determine the factors associated with clinical results of ESD during the learning curve. PATIENTS AND METHODS In total, 44 patients with sessile and flat rectal and...

In this paper, a TSK-type quantum neural fuzzy network (TQNFN) for temperature control is proposed. The TQNFN model is a five-layer structure, which combines the traditional Takagi-Sugeno-Kang (TSK). Layer 2 of the TQNFN model contains quantum membership functions, which are multilevel activation functions. Each quantum membership function is composed of the sum of sigmoid functions shifted by ...

introduction: nowadays,  considerable developments  in  the field  of  radiotherapy have  been  achieved.  they  include  the  advances  made  in  the  equipments  and  treatment  planning  techniques  which  require  highly complex calculations. such achievements have made it possible to treat cancer patients not only  with  higher  radiation  dose  but  also  with  higher  precision  and  con...

Colonoscope looping in the sigmoid colon is ...

BACKGROUND We have previously recognized segmental sigmoid polyps as an indicator of a fistula from Crohn's ileitis to the sigmoid or the proximal rectum. In the course of this study, we realized that many patients with this fistula had no sigmoid polyps, but the sigmoid was the site of marked inflammation and early or late stricture formation. Furthermore, in some patients with a stricture, th...

Abstract Voice activity detection (VAD) based on deep neural networks (DNN) have demonstrated good performance in adverse acoustic environments. Current DNN-based VAD optimizes a surrogate function, e.g., minimum cross-entropy or squared error, at given decision threshold. However, usually works on-the-fly with dynamic threshold, and the receiver operating characteristic (ROC) curve is global e...
