Colorectal and Pelvic Malformations Center, Division of Gastroenterology, Department of Medicine, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA.

Spina bifida is a birth defect that commonly causes bowel and bladder dysfunction in children with a significant negative impact on quality of life and emotional wellbeing. Fecal continence improves satisfaction and the quality of life of both children and their caretakers. Bowel management in children with spina bifida is hampered by limited controlled studies and variable practice within different institutions and subspecialists. Read More

Department of Neurosciences, Operative Unit of Otorhinolaryngology, University of Padova, Via Giustiniani, 2, 35128, Padova, Italy.

Objective: Large intradural growth of tympano-jugular paragangliomas (TJ-PGs) into the cerebellopontine angle is an infrequent condition that can determine an extensive involvement of vessels and brainstem, representing a surgical challenge.

Global Nursing Research Center, Graduate School of Medicine, The University of Tokyo.

We described fecal retention during the defecation cycles of adults with functional constipation via ultrasonography (US) of the large intestine. US was performed continuously after the last defecation until the next defecation. We defined the fecal finding level on US as follows: weak fecal retention, a marginally high echo in the colonic lumen; or strong fecal retention, a strongly echoic colon lumen with showing a crescent-shaped acoustic shadow on transverse images and haustrations on longitudinal images.

Background And Aims:: The optimal extent of mesenteric resection in colon cancer surgery remains elusive. The aim was to assess the impact on perioperative morbidity and oncological outcome depending on the height of central vessel ligation in sigmoid resection for adenocarcinomas.

Material And Methods:: All cases of stage I-III sigmoid cancers, operated on with locally radical resections (2007-2009), were identified in the Swedish Colorectal Cancer Registry and categorized according to the position of the vascular ligature, that is, ligation of the inferior mesenteric artery, ligation of the superior rectal artery, or ligation of the sigmoid branches.

Combined Transpetrosal Approach With Preservation of Superior Petrosal Vein Drainage for a Cerebellopontine Angle Epidermoid Cyst Extending Into Meckel's Cave: 3-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2018 Nov 18. Epub 2018 Nov 18.

Department of Neurosurgery, Tokyo Medical University, Tokyo, Japan.

The combined transpetrosal approach enables wide exposure around the petroclival region by cutting the tentorium and superior petrosal sinus. We often choose this approach for removal of tumors ventral to the facial and vestibulocochlear nerves, such as petroclival meningioma and epidermoid cyst, because complete removal of the tumor under direct visualization is required to prevent its later recurrence, especially in young patients. Recent reports revealed anatomical variations of the drainage of the superior petrosal sinus, and dural incision considering preservation of the superior petrosal vein was proposed. Read More

However, defining effective predictive biomarkers is still challengeable. The 'radiomics' is an established method to identify advanced and high order quantitative imaging features for computer-aided diagnosis and has been applied into oncology study. Read More

Utility of Clot Waveform Analysis in Russell's Viper Bite Victims with Hematotoxicity.

J Emerg Trauma Shock 2018 Jul-Sep;11(3):211-216

Department of Emergency Medicine, Jubilee Mission Medical College and Research Institute, Thrissur, Kerala, India.

Introduction: In Russell's viper bites, due to the lack of a better alternative, whole blood clotting test (WBCT) remains the standard test even though its reliability and sensitivity has been shown to be low. Activated partial thromboplastin time (aPTT)-based clot waveform analysis (CWA) is an optic absorbance assay that can be used as a global clotting test. In this study, the objective was to assess the changes in CWA and to compare CWA to WBCT and aPTT in patients with Russell's viper envenomation. Read More
