OBJECTIVE: The anterior transpetrosal (ATP) approach is the most appropriate approach for petroclival meningiomas, which are typically located from the dorsum sellae to the upper border of the internal acoustic meatus (IAM). Although neurosurgeons can resect over this area if the tumor is detached from the dura, tumors within the indication area for petroclival meningiomas is insufficient for the selection of the ATP approach because it can be difficult to evaluate whether the tumor is attached or only touching the dura...

PURPOSE: Endoscopic sinus surgery (ESS) is a well-established treatment for chronic rhinosinusitis (CRS). However, ESS for frontal sinusitis remains complicated and challenging. The aim of this study was to identify the relationship between residual frontal recess cells and primary ESS failure in the frontal sinus. METHODS: We prospectively collected information on 214 sides of 129 patients with CRS who underwent standard ESS from June 2010 to May 2011. To identify risk factors, we retrospectively analyzed clinical data and computed tomography (CT) images before and 3 months after surgery...

Tau positron emission tomography (PET) imaging has potential for elucidating changes in the deposition of neuropathological tau aggregates that are occurring during the progression of Alzheimer's disease (AD). This work investigates in vivo kinetics, quantification strategies and imaging characteristics of a novel tau PET radioligand [18 F]MK-6240 in humans. Methods: Fifty-one individuals ranging from cognitively normal young controls to persons with dementia underwent T1-weighted magnetic resonance imaging (MRI), and [11 C]PiB and [18 F]MK-6240 PET imaging...

BACKGROUND: Little is known about the association of atrial fibrillation symptom burden with quality of life and outcomes. METHODS AND RESULTS: In the Prevention of Thromboembolic Events-European Registry in Atrial Fibrillation (n=6196 patients with atrial fibrillation; mean±SD age, 71.8±10.4 years; 39.7% women), we assessed European Heart Rhythm Association score symptoms and calculated correlations with the standardized health status questionnaire (EQ-5D-5L)...

Clinical practice guidelines provide evidence-based recommendations. However, many problems are reported, such as contradictions and inconsistencies. For example, guidelines recommend sulfamethoxazole/trimethoprim in child sinusitis, but they also state that there is a high bacteria resistance in this context. In this paper, we propose a method for the semi-automatic detection of inconsistencies in guidelines using preference learning, and we apply this method to antibiotherapy in primary care. The preference model was learned from the recommendations and from a knowledge base describing the domain...

BACKGROUND: To evaluate the clinical efficacy and safety of latissimus dorsi myocutaneous flap (stage I) combined with iliac bone flap (stage II) in the treatment of chronic osteomyelitis of the lower extremity. METHODS: Clinical data of 18 patients undergoing latissimus dorsi myocutaneous flap in combination with iliac bone flap grafting were retrospectively analyzed. Among them, 2 patients developed chronic osteomyelitis of the lower segment of the femur, 4 were diagnosed with chronic osteomyelitis of the tibial plateau, and 12 with chronic osteomyelitis of the lower segment of the tibia...

BACKGROUND:  Microvascular reconstruction of the anterior cranial fossa (ACF) creates difficult challenges. Reconstructive goals and flap selection vary based on the defect location within the ACF. This study evaluates the feasibility and reliability of free tissue transfer for salvage reconstruction of low, middle, and high ACF defects. METHODS:  A retrospective review was performed. Reconstructions were anatomically classified as low (anterior skull base), middle (frontal bar/sinus), and high (frontal bone/soft tissue)...

Cardiovascular autonomic neuropathy (CAN) is a well known prognostic marker in diabetes. A large angle between the QRS- and the T-wave vector (QRS-T angle) in the electrocardiogram (ECG) has recently been introduced as another marker of poor prognosis. AIM: To assess and compare the long-term predictive power of the frontal plane QRS-T angle with CAN in people with diabetes. METHODS: In 1992-93 people with diabetes in the municipality of Horsens, Denmark, were identified by the prescription method andan age and gender stratified sample of 240 individuals with diabetes were randomly selected...

Rationale To prevent recurrent venous thrombotic events after acute cerebral venous or dural sinus thrombosis, guidelines recommend long-term oral anticoagulation with vitamin K antagonists. Non-vitamin K oral anticoagulant experience in cerebral venous or dural sinus thrombosis is limited to case reports and series. Aim To compare dabigatran with dose-adjusted warfarin in patients with cerebral venous or dural sinus thrombosis for the prevention of recurrent venous thrombotic event. Sample size One hundred and twenty patients...

OBJECTIVE The endoscopic endonasal approach (EEA) and the transcranial approach (TCA) are good options for the treatment of tuberculum sellae (TS) meningiomas. The objective of this study was to identify the key anatomical features in TS meningiomas and compare the two surgical approaches. METHODS The authors retrospectively reviewed clinical data in 178 patients with TS meningiomas treated at 3 institutions between January 2010 and July 2016. Patients with tumors encasing the internal carotid artery or anterior cerebral artery or involving the anterior clinoid process or cavernous sinus were excluded...

OBJECTIVE The transpterygoid extension of the endoscopic endonasal approach provides exposure of the petrous apex, Meckel's cave, paraclival area, and the infratemporal fossa. Safe and efficient localization of the lacerum segment of the internal carotid artery (ICA) is a crucial part of such exposure. The aim of this study is to introduce a novel landmark for localization of the lacerum ICA. METHODS Ten cadaveric heads were prepared for transnasal endoscopic dissection. The floor of the sphenoid sinus was drilled to expose an extension of the pharyngobasilar fascia between the sphenoid floor and the pterygoid process (the pterygoclival ligament)...

Chronic rhinosinusitis (CRS) is a common disease of otorhinolaryngology head and neck surgery, manifested as nasal-sinus mucosal chronic inflammation. However, the pathogenesis of CRS is not clear. There are studies found that microRNA (miRNA) involved in CRS gene regulation. In this review, we summarize the expression of miRNAs in CRS, with the in-depth study of the role of miRNAs in CRS, and will further elucidate the pathogenesis of CRS.

Method: A total of thirty-four patients with frontal sinusitis after transfrontal craniotomy were admitted, with the symptom of purulence stuff, headache and upper eyelid discharging. The onset time was 2.6 years on average. The frontal sinus CT and MRI images showed frontal sinusitis. Twenty-seven patients were treated with endoscopic frontal sinus surgery, and seven patient was treated with combined endoscopic and traditional frontal sinus surgery...

Objective: The aim of this study is to explore the value of 3D reconstruction technology based on computer tomography data in understanding the frontal sinus drainage pathway. Method: Three-dimensional reconstruction of DICOM data from 100 cases of sinus CT was performed by using Mimics 19.0 software. The 3D models were used to study types, the relative locations of frontal sinus and recess cells as well as the influence of the frontal sinus drainage pathway. Result: The 3D model of frontal sinus, frontal recess cells and frontal sinus drainage pathway were reconstructed successfully...

Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms...

BACKGROUND Pathological finding fail to describe the morphology of coronary arterial plaques. Retrograde cardiac arteriography is a complicated procedure and does not detect all left posterior and marginal veins of the heart. Magnetic resonance angiography has long scan time and low spatial resolution. The objective of the present study was to assess the possible utility of the difference in coronary sinus diameter to quantify stable atherosclerotic plaque(s) using 256-slice coronary computed tomographic angiography...
