[A Very Rare Case of Diffuse Subependymal Metastases from Small Cell Lung Carcinoma].

While parenchymal metastases are common in solid systemic cancers, subependymal metastases are rare. Approximately half of the reported cases of intraventricular metastases originate from renal carcinoma. A 65-year-old man presented with general fatigue, appetite loss, nausea, and disorientation.

Analysis of the Outcomes in Central Venous Access Port Implantation Performed by Residents via the Internal Jugular Vein and Subclavian Vein.

Objective: The central venous access port (CVAP) has played an important role in the safe administration of chemotherapy and parenteral nutrition. The aim of the present study was to clarify the optimal access vein for CVAP implantation when performed by residents rather than attending surgeons.

Methods: A consecutive cases of CVAP implantation via the subclavian vein (SV) using a landmark-guided technique or via the internal jugular vein (JV) using an ultrasound-guided technique were divided into 2 groups according to whether the intervention was performed by a resident or an attending surgeon.

[Internal Carotid Artery Stenosis Associated with Hyoid Bone:Can Hyoid Bone be a Risk Factor for Acute Cerebrovascular Syndrome?].

Eagle syndrome is a well-known disease caused by elongation of the styloid process and/or calcification of the stylohyoid ligament, which interferes with adjacent anatomical structures, giving rise to acute cerebrovascular syndrome(ACVS)and/or pain. Although hyoid bone is also a stylohyoid complex, its association with ACVS is not well known. Thus, we investigated the anatomical relationship between the internal carotid artery(ICA)and the hyoid bone.

The effects of intravenous anesthetics on QT interval during anesthetic induction with sevoflurane.

Purpose: Sevoflurane is known to prolong the QT interval. This study aimed to determine the effect of the interaction between intravenous anesthetics and sevoflurane on the QT interval.

Methods: The study included 48 patients who underwent lumbar spine surgery.

Comparison of clinical outcomes between laminoplasty, posterior decompression with instrumented fusion, and anterior decompression with fusion for K-line (-) cervical ossification of the posterior longitudinal ligament.

Purpose: The K-line, which is a virtual line that connects the midpoints of the anteroposterior diameter of the spinal canal at C2 and C7 in a plain lateral radiogram, is a useful preoperative predictive indicator for sufficient decompression by laminoplasty (LMP) for ossification of the posterior longitudinal ligament (OPLL). K-line is defined as (+) when the peak of OPLL does not exceed the K-line, and is defined as (-) when the peak of OPLL exceeds the K-line. For patients with K-line (-) OPLL, LMP often results in poor outcome.

The Ulnar Nerve at Elbow Extension and Flexion: Assessment of Position and Signal Intensity on MR Images.

Purpose To assess the position and signal intensity of the ulnar nerve at elbow extension and flexion by using magnetic resonance imaging. Materials and Methods Institutional review board approval and written informed consent were obtained. Transverse T2-weighted images were obtained perpendicular to the upper arm in 100 healthy elbows of 50 volunteers (23 men, 27 women; age range, 21-57 years) and nine elbows with ulnar neuropathy (five men, four women; age range, 24-59 years) with extension and 130° of flexion.

[A Rare Case of Subependymoma of the Septum Pellucidum as Intratumoral Hemorrhage].

Subependymomas (SEs) are rare, benign, noninvasive, slow-growing tumors located anywhere along the ventricular walls. They arise most frequently in the fourth ventricle followed by the lateral ventricle, and less frequently in the septum pellucidum, third ventricle, and spinal cord. Most SEs are found incidentally at autopsy, but some may produce clinical symptoms.

An observational study of the association between microalbuminuria and increased N-terminal pro-B-type natriuretic peptide in patients with subarachnoid hemorrhage.

Background: The urinary albumin/creatinine ratio (ACR) is a significant neurologic prognostic predictor in patients with aneurysmal subarachnoid hemorrhage (SAH). B-type natriuretic peptide (BNP) plays an important role in body fluid regulation in patients with SAH. The present study was performed to determine whether ACR was independent predictor for unfavorable neurological outcome and ACR was associated with increased N-terminal pro-BNP (NT-pro-BNP) after SAH.

Successful treatment of a ruptured spontaneous dissecting coronary artery pseudoaneurysm with a covered stent in a patient with cardiac tamponade.

The rupture of spontaneous dissecting coronary artery pseudoaneurysms is rare, and no standard therapy has yet been established for this condition. This report describes a case of a ruptured spontaneous dissecting coronary artery pseudoaneurysm in a patient with cardiac tamponade that was successfully treated with emergent implantation of a covered stent.

Potential risk factors of persistent low back pain developing from mild low back pain in urban Japanese workers.

Study Design: Two-year, prospective cohort data from the Japan epidemiological research of occupation-related back pain study in urban settings were used for this analysis.

Objective: To examine the association between aggravated low back pain and psychosocial factors among Japanese workers with mild low back pain.

Summary Of Background Data: Although psychosocial factors are strongly indicated as yellow flags of low back pain (LBP) leading to disability, the association between aggravated LBP and psychosocial factors has not been well assessed in Japanese workers.

[Risk factors for low back pain and katakori: a new concept].

Low back pain (LBP) is a common musculoskeletal health problem in industrialized countries and one of the worst leading specific causes of years lived with disability. We conducted a cohort study specifically targeting Japanese workers. Results suggest that psychosocial factors such as low job satisfaction, little social support, depression, and somatization are important risk factors for aggravating LBP and are consistent with foreign studies despite cultural differences.

Identification of risk factors for new-onset sciatica in Japanese workers: findings from the Japan epidemiological research of Occupation-related Back pain study.

Study Design: Two-year, prospective cohort data collected for the Japan epidemiological research of Occupation-related Back pain study were used for the analysis.

Objective: To identify potential risk factors for the development of new-onset sciatica in initially symptom-free Japanese workers with no history of sciatica.

Summary Of Background Data: Although the associations between individual and occupational factors and cases of new-onset sciatica are established, the effect of psychosocial factors on the development of sciatica has still not been adequately clarified.

The interaction of antiemetic dose of droperidol with propofol on QT interval during anesthetic induction.

Purpose: We investigated the effect of low-dose droperidol on heart rate-corrected QT (QTc) interval and interaction with propofol.

Methods: Seventy-two patients undergoing upper limb surgery were included in this study. Patients were randomly allocated to one of three groups: group S (n = 24), which received 1 ml saline; group D1 (n = 24), which received 1.

Effect of pimobendan in addition to standard therapy for heart failure on prevention of readmission in elderly patients with severe chronic heart failure.

Aim: We evaluated the effect of pimobendan, a positive inotropic agent, in elderly patients with frequent readmission as a result of heart failure despite conventional therapy.

Methods: Pimobendan was given to five male patients with severe chronic heart failure (New York Heart Association class III-IV) (age range 69-89 years; mean 78 ± 8 years; ischemic cardiomyopathy in three cases, dilated cardiomyopathy in two cases) who required repeated admission for heart failure despite conventional therapy with angiotensin inhibitors, beta-blockers, diuretics and anti-arrhythmic agents. After the addition of pimobendan at a dose of 1.

Differential effects of propofol and sevoflurane on QT interval during anesthetic induction.

There have been conflicting reports on whether propofol prolongs, shortens, or does not change QT interval. The aim of this study was to determine the effect of target-controlled infusion (TCI) of propofol on heart rate-corrected QT (QTc) interval during anesthetic induction. We examined 50 patients undergoing lumbar spine surgery.

[Intraorbital schwannoma arising from the supraorbital nerve].

A 67-year-old man presented a three-month history of double vision and slight numbness at his right forehead. Neurological examination on admission demonstrated diplopia at lower gaze and mild hypesthesia at right frontal. MRI disclosed an extraconal cystic mass, centered over the superior rectus muscle, in the superior part of the right orbit.

Comparison between propofol and dexmedetomidine in postoperative sedation after extensive cervical spine surgery.

Purpose: Patients undergoing extensive cervical spine surgery (ECSS) occasionally require emergency reintubation due to postoperative airway complications. To avoid it, an endotracheal tube is retained in patients maintained under sedation overnight. This study was conducted to determine whether dexmedetomidine would be superior in sedative effects to propofol for postoperative sedation after ECSS.

Background: The present study was conducted to determine the relationship between magnesium concentration in cerebrospinal fluid (CSF) and delayed cerebral ischemia (DCI) in patients with subarachnoid hemorrhage (SAH).

Methods: We studied 39 consecutive patients undergoing surgery after SAH. A spinal drainage catheter was inserted into the lower lumbar vertebrae before surgery.

Takotsubo cardiomyopathy in a patient with severe hyponatremia associated with syndrome of inappropriate antidiuretic hormone.

Although the etiology of Takotsubo cardiomyopathy (stress-induced cardiomyopathy) is unknown, there is a wide variability in the psychological and physical triggers for Takotsubo cardiomyopathy. We report here a case of Takotsubo cardiomyopathy associated with severe hyponatremia.

Laparoscopy-assisted right hepatectomy in a case of Fasciola hepatica.

Laparoscopic hepatectomy provides the usual advantages of a minimally invasive surgery. This study presents a case of Fasciola hepatica infection that was successfully treated with laparoscopic hepatectomy. The patient was referred because of persistent fever and right hypochondralgia with a huge mass occupying the right lobe of the liver, which was detected by imaging analysis.

Foreign body granulomatous change from absorbable gelatin sponge and microcoil embolization after a guidewire-induced perforation in the distal coronary artery.

We report an autopsy case of treatment by absorbable gelatin sponge and microcoil embolization after perforation of the distal coronary artery by guidewire. Histological examination revealed a foreign body granuloma in the coronary artery with embolization. Foreign body reaction to absorbable gelatin sponge seemed to be stronger than that to the microcoil.

Premature atrial contraction induces torsades de pointes in a patient of Takotsubo cardiomyopathy with QT prolongation.

Although the prognosis for patients with stress-induced cardiomyopathy (Takotsubo cardiomyopathy) is relatively good, some patients with this syndrome develop torsades de pointes, which can be fatal. The present report describes a patient with Takotsubo cardiomyopathy and torsades de pointes induced by premature atrial contraction associated with QT interval prolongation, hypokalemia and hypomagnesemia.
