Analysis on death-associated factors of patients with subarachnoid hemorrhage during hospitalization.
The prognosis of patients with high-clinical-score subarachnoid hemorrhage remains poor, with early high mortality rate. Therefore, to predict the early outcome of patients after subarachnoid hemorrhage, several clinical factors were hypothesized to be related to death during hospitalization. ⋯ Increased white blood cell count may indicate poor outcomes for patients during hospitalization, even early death.

Mechanism of action of oxygen ozone therapy in the treatment of disc herniation and low back pain.
In the low back syndrome the pain has a multifactorial origin and ozone can surprisingly display a number of beneficial effects ranging from the inhibition of inflammation, correction of ischemia and venous stasis, and finally inducing a reflex therapy effect by stimulating anti-nociceptor analgesic mechanisms. The intradiscal and intramuscular injection of oxygen-ozone is a successful approach comparable to other minimally invasive procedures, but the elucidation of the mechanisms of action remains elusive. This communication shortly reports the mechanisms of action of oxygen ozone therapy at the level of intervertebral disc and paravertebral muscles.

Intraoperative imaging technologies have improved surgical results in glioma and pituitary adenoma surgeries. With improvements and refinements 3T intraoperative MRI systems offer a potential of further improving these results. Hereby we describe the equipment and technique of a cost-effective shared-resource 3-T ultra-high field intraoperative magnetic resonance imaging system and report our continuing experience on surgical tumor resection. ⋯ Operation is performed using regular non-MRI compatible equipment and the patient is transferred to the MRI during the procedure using a custom designed floating table. Advanced sequences such as diffusion weighted and diffusion tensor imaging, MR angiography, MR venography, MR spectroscopy can be performed with no changes in the setup and result in image quality comparable to outpatient scans. The intraoperative 3-T ultra high field MRI unit with the twin room concept permits both diagnostic outpatient imaging and image guided surgery in the same setting and is a cost effective solution to afford a highly capable ioMRI system.

Subarachnoid hemorrhage causes pulmonary endothelial cell apoptosis and neurogenic pulmonary edema in mice.
Neurogenic pulmonary edema (NPE) is a well-known complication of subarachnoid hemorrhage (SAH), which potentially causes a poor outcome. The aim of this study was to examine if NPE occurs in the endovascular perforation model of SAH in mice and if apoptosis contributes to NPE development after SAH in mice. ⋯ Pulmonary endothelial cell apoptosis contributes to the pathophysiology of NPE after SAH in mice.

Anatomic study in cadaver of the motor branch of the musculocutaneous nerve.
This study of 80 cadavers demonstrates that the anatomic position of the motor branch of the musculocutaneous nerve with respect to that of the sensitive branch of the same nerve is lateral in more than 88% of cases in humans.The distance from plexus to the separation into the motor and sensitive fascicles was 8-9 cm long.Given the lateral position of the motor component of the musculocutaneous nerve, the nerves that are going to be used to neurotize this area can be directed so as to increase the efficacy of the results for the flexor function of the arm. ⋯ If the nerves that are to be used for neurotization of the musculacutaneous nerve are directly taken to the lateral fascicle of that nerve, which is generally the motor component, the treatment should be effective and should avoid the loss of motor axons resulting from anastomosing to the sensitive fascicle.
