Risk factors for incidental durotomy during posterior open spine surgery for degenerative diseases in adults: A multicenter observational study.

Incidental durotomy (ID) is a common intraoperative complication of spine surgery. It can lead to persistent cerebrospinal fluid leakage, which may cause serious complications, including severe headache, pseudomeningocele formation, nerve root entrapment, and intracranial hemorrhage. As a result, it contributes to higher healthcare costs and poor patient outcomes.

Chlorogenic acid regulates apoptosis and stem cell marker-related gene expression in A549 human lung cancer cells.

Previous studies indicated that chlorogenic acid, a compound present in many fruits and vegetables, has anti-cancer activities. We report that chlorogenic acid regulates the expression of apoptosis-related genes and self-renewal-related stem cell markers in cancer cells. The lung cancer cell line A549 was cultured with or without chlorogenic acid.

The pseudo-SAH sign: an imaging pitfall in postmortem computed tomography.

Postmortem computed tomography (PMCT) of the brain has an important role in detection of subarachnoid hemorrhage (SAH), which has a high mortality rate. However, a phenomenon known as "pseudo-SAH," or high-attenuation areas along the cisterns mimicking SAH, may be seen on CT. The aim of this study was to evaluate the diagnostic accuracy of brain PMCT for SAH and to identify the characteristics of pseudo-SAH.

Effect of ezetimibe add-on therapy over 52 weeks extension analysis of prospective randomized trial (RESEARCH study) in type 2 diabetes subjects.

Effective ways to stably reduce LDL-C level are warranted in type 2 diabetic patients, a high-risk population for CVD, with various anti-diabetic therapeutic background. The RESEARCH study focuses on LDL-C reduction in this population along with modifications of the lipid profiles.

Anterior cage dislodgement in posterior lumbar interbody fusion: a review of 12 patients.

OBJECTIVE Interbody fusion cages are widely used to achieve initial fixation and secure spinal fusion; however, there are certain technique-related complications. Although anterior cage dislodgement can cause major vascular injury, the incidence is extremely rare. Here, the authors performed a review of anterior cage dislodgement following posterior lumbar interbody fusion (PLIF) surgery.

Premedication with fast-acting oxycodone hydrochloride hydrate effectively reduced oxaliplatin-induced severe vascular pain.

Oxaliplatin is a platinum-based chemotherapeutic agent that holds a prominent position in the treatment of colorectal and gastric cancers. However, severe oxaliplatin-related vascular pain can be problematic for patients. Here we describe seven patients who experienced severe vascular pain caused by oxaliplatin administration.

Suturing method as a factor for uterine vascularity after laparoscopic myomectomy.

Objective: To evaluate the vascularity of the myometrium after laparoscopic myomectomy sutured by two different methods using contrast-enhanced Magnetic Resonance Imaging.

Study Design: Twenty-eight women who had symptomatic leiomyomas and underwent laparoscopic myomectomy between June 2013 and July 2014 were included in the present study. In the first half period, continuous sutures were used in 12 patients, and in the latter half period, single interrupted sutures were used in 16 patients.

Comparison of the cardiothoracic ratio between postmortem and antemortem computed tomography.

As postmortem imaging has gained prominence as a supplement to traditional autopsy, it is important to understand the normal postmortem changes to enable the accurate evaluation of postmortem imaging. No studies have evaluated the postmortem changes in cardiothoracic ratio (CTR) compared with antemortem images in the same subjects. We studied 147 consecutive subjects who underwent antemortem and postmortem CT, and autopsy.

Can postmortem computed tomography detect antemortem hypoxic-ischemic encephalopathy?

The purpose of this study was to evaluate the usefulness of brain postmortem computed tomography (PMCT) findings for the detection of global hypoxia or hypoperfusion leading to hypoxic-ischemic encephalopathy (HIE) prior to death. Cadavers of individuals who died from non-traumatic causes were subjected to PMCT and pathological autopsy. Cases with an episode of cardiopulmonary arrest, hypoxia, or hypoperfusion that required intensive respiratory management at least 24 h before death and exhibited findings of HIE in conventional autopsy (HIE group, n = 6) were compared with those without such episodes prior to death (control group; overall, n = 37; age-matched, n = 8) with regard to four parameters: (1) width of the central sulcus (CS), (2) attenuation difference at the basal ganglia (BG) level, (3) attenuation difference between cerebral gray matter (GM) and cerebral white matter (WM), and (4) attenuation difference between cerebellar GM and cerebral GM.
