We report the usefulness of ICG-VA for Sylvian fissure dissection in patients with subarachnoid hemorrhage (SAH).

Chronic Subdural Hematoma in Elderly Patients: Is This Disease Benign?

As the world population becomes progressively older, the overall incidence of chronic subdural hematoma (CSDH) is increasing. Peak age of onset for CSDH has also increased, and recently the 80-year-old level has a peak. Many patients with CSDH have had prior treatment with anticoagulants and antiplatelet drugs, which have an accompanying risk of CSDH.

Present epidemiology of chronic subdural hematoma in Japan: analysis of 63,358 cases recorded in a national administrative database.

OBJECTIVE Aging of the population may lead to epidemiological changes with respect to chronic subdural hematoma (CSDH). The objectives of this study were to elucidate the current epidemiology and changing trends of CSDH in Japan. The authors analyzed patient information based on reports using a Japanese administrative database associated with the diagnosis procedure combination (DPC) system.

Surgical results of lumbar interbody fusion using calcium phosphate cement.

Clinical and radiological outcomes of lumbar interbody fusion using artificial fusion cages filled with calcium phosphate cements (CPCs) were retrospectively reviewed. Between 2002 and 2011, 25 patients underwent lumbar interbody fusion at Tokushima University Hospital, and 22 patients were enrolled in this study. Of these, 5 patients received autologous local bone grafts and 17 received CPC.

Chronic encapsulated intracerebral hematoma: Three case reports and a literature review.

Background: Chronic encapsulated intracerebral hematoma (CEIH) is one type of intracerebral hematoma that sometimes grows progressively while forming a capsule and presenting with neurological deficits. Although many cases of CEIH have been reported, correct preoperative diagnosis is very difficult. Only around 20% of cases are diagnosed preoperatively.

Facilitation of endoglin-targeting cancer therapy by development/utilization of a novel genetically engineered mouse model expressing humanized endoglin (CD105).

Endoglin (ENG) is a TGF-β coreceptor and essential for vascular development and angiogenesis. A chimeric antihuman ENG (hENG) monoclonal antibody (mAb) c-SN6j (also known as TRC105) shows promising safety and clinical efficacy features in multiple clinical trials of patients with various advanced solid tumors. Here we developed a novel genetically engineered mouse model to optimize the ENG-targeting clinical trials.

Background: Standard treatment for acute cholecystitis (AC) in patients receiving antithrombotic drugs has not been established. We evaluated the safety of percutaneous transhepatic gallbladder drainage (PTGBD) followed by elective laparoscopic cholecystectomy (LC) in patients with moderate AC who were receiving antithrombotics.

Methods: Seventy-five patients received PTGBD from January 2006 to March 2013 followed by elective LC for moderate AC.

Prediction of cerebral vasospasm using early stage transcranial Doppler.

Transcranial Doppler (TCD) is widely used to monitor vasospasm after subarachnoid hemorrhage (SAH), but its ability to predict the future occurrence of the symptomatic vasospasm (SVS) remains controversial. We investigated the utility of TCD for predicting the future occurrence of SVS after SAH in 45 patients with aneurysmal SAH. TCD was performed on days 1, 3, 5, 7, 10, and 14 after SAH.

Microbleeds as a prognostic factor for acute subdural hematoma.

This study investigated the frequency of poor outcome at discharge of acute subdural hematoma (SDH) patients with and without microbleeds. We retrospectively examined the records of 37 patients with acute SDH who were surgically treated with hematoma removal and received magnetic resonance (MR) imaging within 2 weeks of head injury onset. MR images were used to determine the presence or absence of microbleeds and contusional hemorrhage (CH).
