OBJECTIVE To determine whether quantitative perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) correlate with immunohistochemical markers of angiogenesis in rectal cancer. MATERIALS AND METHODS Preoperative DCE-MRI was performed in 63 patients with rectal adenocarcinoma. Transendothelial volume transfer (K(trans) ) and fractional volume of the extravascular...

This project was designed to study the incidence, onset, duration and potency of tramadol, in donkeys can be evaluated as local anesthetic drug by infiltration maxillary sinus for trephination. In this study, five adult both sexes breed were used induce trephination that given 2% xylazine hydrochloride intravenously followed 5% tramadol with aseptic technique. Parameters evaluation, physical cl...

INTRODUCTION Retro-rectal cystic hamartoma (tailgut cyst) is a rare congenital developmental lesion arising from post-natal primitive gut remnants in the retro-rectal space. The rarity of the lesion and its anatomical position usually leads to difficulty in diagnosis and surgical management. Complete surgical resection remains the cornerstone of treatment. A dozen or so surgical approaches have...

INTRODUCTION The diagnosis of trans-anal rectal injuries is usually delayed because of the patient's denial. Some of these injuries are self-inflicted or caused by criminal assault, leading to delayed presentation. We aimed to study the causes, clinical presentation, management and clinical outcome of transanal rectal injuries. METHODS The records of 12 patients (nine males) with a median age...

In vivo trans-rectal near-infrared (NIR) optical tomography was performed concurrently with, albeit reconstructed without spatial a prior of, trans-rectal ultrasound (US) on transmissible venereal tumor (TVT) developed as a model in the canine pelvic canal. Studies were taken longitudinally at prior to, 14 days after, and 35 days after the TVT injection. As the tumor grew, the nodules became in...

A total of 378 ewe lambs were evaluated for signs of pregnancy using five methods of detection. The methods used were breeding mark, rectal-abdominal palpation, an intrarectal Doppler instrument and two ultrasonic devices, the Scanoprobe and Scanopreg (Model 738) for sheep. Accuracies of pregnancy diagnosis based on grease marks at mating vs lambing results were 65.7% in 1976 and 75.5% in 1977 ...

Methamphetamine (MA) use is becoming commonplace, and emergency physicians (EPs) are seeing patients with abuse-associated complications. Previous reports have described inhalational and intravenous routes. We present the second case of rectal MA abuse in the literature. Trans-rectal use is important for EPs to consider because ongoing absorption of massive quantities may be averted upon detect...

for paper in IEEE Transactions on Information Technology in Biomedicine This work seeks to quantify finger palpation techniques in the prostate clinical exam, determine their relationship with performance in detecting abnormalities, and differentiate the tendencies of nurse practitioner students and resident physicians. One issue with the digital rectal examination (DRE) is that performance in ...

The simulation of organ-organ interaction is indispensable for practical and advanced medical VR simulator such as open surgery and indirect palpation. This paper gives a method to represent interaction between elastic objects i.e. organs in medical VR simulation. The proposed model defines displacements of colliding elements based on temporary surface forces caused by temporary displacements, ...

Palpation of organs is one of the oldest clinical examination techniques, for instance, if you think of the palpation of the breast or the digital rectal examination of the prostate, where hard palpable regions are suspicious for cancer. This is the basic principle of real-time elastography, an ultrasound technique, which is able to visualise tissue elasticity. Since prostate cancer features an...
