microRNA 21 (miRNA‑21) promotes the development of cardiac fibrosis, hypertrophy and heart failure. However, whether it can be used as a biomarker for the diagnosis and prognosis of heart failure remains unclear. The current study assessed circulating miRNA‑21 as a viable indicator for diagnosis and prognosis of heart failure. The levels of miRNA‑21 and brain natriuretic peptide were measured in serum obtained from the peripheral vein (miRNA‑21‑PV) and coronary sinus (miRNA‑21‑CS) of 80 patients with heart failure and 40 control individuals via reverse transcription‑quantitative polymerase chain reaction and ELISA, respectively...

Cerebral venous sinus thrombosis (CVST) is generally treated with anticoagulation therapy, however, endovascular therapy is considered for refractory cases. A 42-year-old woman presented with a progressive disturbance in consciousness, and diagnosed CVST in the straight sinus (SS). Recanalization of SS was achieved by emergent thrombectomy using aspiration catheter and stent-retriever system, and her level of consciousness improved immediately. The combined use of them aided the removal of the thrombus located in the SS...

BACKGROUND: One of the most common primary cardiac arrhythmia syndromes is autosomal dominant long QT syndrome, type 1 (LQT1), chiefly caused by mono-allelic mutations in the KCNQ1 gene. Bi-allelic mutations in the KCNQ1 gene are causal to Jervell and Lange-Nielsen syndrome (JLNS), characterized by severe and early-onset arrhythmias with prolonged QTc interval on surface ECG and sensorineural deafness. Occasionally, bi-allelic mutations in KCNQ1 are also found in patients without any deafness, referred to as autosomal recessive long QT syndrome, type 1 (AR LQT1)...

Scanning-beam digital x-ray (SBDX) is an inverse geometry x-ray fluoroscopy system capable of tomosynthesis-based 3D tracking of catheter electrodes concurrent with fluoroscopic display. To facilitate respiratory motion-compensated 3D catheter tracking, an automated coronary sinus (CS) catheter detection algorithm for SBDX was developed. The technique uses the 3D localization capability of SBDX and prior knowledge of the catheter shape. Candidate groups of points representing the CS catheter are obtained from a 3D shape-constrained search...

Objective It remains unclear whether the CHADS2, CHA2DS2-VASc, or R2CHADS2 score is the most useful for the risk stratification of ischemic stroke/systemic thromboembolism (IS/SE) in Japanese patients with paroxysmal non-valvular atrial fibrillation (PNVAF). Methods and Results We investigated the incidence of IS/SE on the basis of the CHADS2, CHA2DS2-VASc, and R2CHADS2 scores in 332 consecutive PNVAF patients (224 men, mean age: 65±13 years) who had not been administered anticoagulation therapy but who were administered antiarrhythmic drug therapy to maintain sinus rhythm between August 1995 and July 2008 before the 2008 Japanese Circulation Society guideline was issued (mean follow-up period: 53±35 months)...

OBJECTIVE: Functional endonasal sinus surgery (FESS) is widely practiced and is considered a generally safe procedure. Skull base injuries occur in less than 1% of procedures and are typically associated with cerebrospinal fluid leaks. Rarely, skull base injuries might result in cerebral lesions. Here we present a series of four patients with iatrogenic perforating injuries of the anterior skull base and cerebral lesions after routine FESS. METHODS: Four patients with iatrogenic perforating cerebral lesions after routine FESS performed at other institutions were referred to a tertiary neurosurgery department within a 10-year period...

A 14-year-old American Staffordshire terrier was presented for episodes of exercise-induced syncope. At admission, atrial flutter coupled to third-degree atrioventricular block was diagnosed electrocardiographically. On the second day of hospitalization, surface electrocardiogram revealed spontaneous conversion to sinus rhythm with persistence of atrioventricular block. Complete transthoracic echocardiograms were performed after each electrocardiographic examination. The combined use of conventional echocardiography with tissue Doppler imaging-based modalities allowed to investigate the atrial electromechanical correlation and function during typical atrial flutter and after its resolution...

Dural arteriovenous fistula (DAVF) have been treated by transarterial or transvenous embolization, surgery, and radiosurgery. Besides these treatment options, the external compression technique is a non-invasive, low-cost form of treatment. This article reports that a 60-year-old man with DAVF between multiple arterial branches and transverse/sigmoid sinus was treated by repeated external manual compression method.

PURPOSE: The current staging system of central nervous system (CNS) germ cell tumors (GCT) includes a binary classification in "localized" or "metastatic" disease based on the absence or presence of leptomeningeal dissemination. Loco-regional tumor dissemination has been barely described whereas its accurate definition might be useful in terms of prognosis and treatment, especially for radiation therapy planning. Our purpose was therefore to describe MR patterns and prevalence of loco-regional extensions of these tumors...

REVIEW
Irene A Kim, Kofi D Boahene, Patrick J Byrne
The optimal management of frontal sinus fractures remains controversial. Fortunately, the severity of these injuries has diminished with more stringent auto-safety regulations, changing the treatment paradigms used to repair these injuries. Appropriate patient selection and close follow-up may allow for conservative management strategies when dealing with frontal sinus fractures, largely replacing the more morbid and invasive techniques that have been the mainstay for years. Because acute and delayed sequelae can arise after the initial injury, patients should be thoroughly counseled about the importance of follow-up and the need to seek medical care if they develop any concerning signs or symptoms...

BACKGROUND: In many developed countries, wait times for elective surgery are increasing. Among these elective surgeries is endoscopic sinus surgery (ESS) performed for treatment of chronic rhinosinusitis (CRS). Little is known about the impact of wait times on patients' surgical outcomes. The purpose of this study was to evaluate the association between patients' wait times and postoperative patient-reported outcomes. METHODS: This study was based on a prospectively recruited longitudinal cohort of patients booked for ESS for the treatment of medically-refractory CRS in Vancouver, Canada...
