BACKGROUND/AIM: Nuclear protein in testis (NUT) carcinoma is extremely rare, occurs in the midline of the body, progresses rapidly and is refractory to treatment; most patients die within a year. Here, we describe a case of maxillary sinus NUT carcinoma presenting with epistaxis and nasal obstruction that was treated as a standard head and neck carcinoma. CASE REPORT: The patient was a 41-year-old male with a left buccal swelling; the diagnosis was made of primary NUT carcinoma of the left maxillary sinus and bone metastasis in the cervical spine...

BACKGROUND: Complex atrial tachycardia (AT) is commonly observed in patients with cardiac surgery. High-density mapping is widely adopted for catheter ablation of complex AT in patients with cardiac surgery. Several case reports have described that PentaRay mapping catheter can be trapped in the mechanical valve and sheared off and successful retrieval of the spline by a snare system. We described a rare case in which PentaRay mapping catheter spline was successfully retrieved from the distal anterior tibial artery by direct syringe suction via the diagnostic catheter following entrapment in the mechanical mitral valve (MV) and rupture of the spline...

The exact processes underlying atrial fibrillation (AF) are still unclear. It has been suggested that epicardial adipose tissue (EAT) may contribute to arrhythmias and can release various bioactive molecules, including exosomes containing tRNA-derived small RNAs (tsRNAs). Numerous studies have indicated that these tsRNAs can significantly affect key cellular functions. However, there is currently no research investigating the relationship between tsRNAs from EAT and AF. In order to explore the regulatory mechanisms of tsRNAs from EAT associated with AF, we conducted RNA-sequencing analysis on EAT samples collected from 6 AF patients and 6 control subjects with sinus rhythm...

OBJECTIVE: Non-contrast computed tomography (CT) of the brain is a primary neuroimaging modality in emergency patients suspected of having cerebral venous sinus thrombosis (CVST). The objective of the study was to determine the diagnostic accuracy of Hounsfield unit (HU) values and the ratio of HU to hematocrit value (HU/Htc) in predicting CVST in suspected patients. MATERIAL AND METHODS: A retrospective, case-control study was done in a tertiary care institute which included 35 patients with CVST constituted as cases and 41 patients without CVST as controls on the basis of magnetic resonance venography (MRV)...

Silent sinus syndrome is a rare clinical entity affecting the maxillary sinus, characterized by ipsilateral enophthalmos and hypoglobus. Its etiology and pathophysiology are still debated. It is diagnosed by clinical examination and confirmed with computed tomography. It is commonly managed surgically. We present the case of a 34-year-old woman with silent sinus syndrome treated with a patient-specific implant for orbital reconstruction, functional endoscopic sinus surgery approach, intraoperative scan, and surgical navigation, successfully restoring orbital volume and sinus ventilation...

The implantation of cardiac pacing devices, such as pacemakers and implanted cardioverter-defibrillators (ICDs), has significantly improved patient outcomes in the treatment of a range of cardiac arrhythmias. Right ventricular (RV) pacing lead perforation is an uncommon but potentially dangerous complication that can occur despite technical breakthroughs. RV lead perforation, which can result in right ventricular perforation as well as possible pulmonary or vascular harm, is caused by the pacing lead breaking through the myocardial wall...

A novel strategy for the treatment of allergic rhinitis results from the innovative combination of antihistamine and intranasal corticosteroid drugs. By combining two preparations with different mechanism of action, this novel approach facilitates quick and effective controls of all upper respiratory tract allergy symptoms. The article presents the results of a study of olopatadine hydrochloride and mometasone furoate fixed-dose combination (GSP301) administered intranasally from a spray formulation, with an attempt at positioning the treatment within the ARIA and EPOS guidelines...

A 47-year-old male patient with a history of Takayasu arteritis presented with prominent symptoms of left eyeball fixation, protrusion, and visual loss. Orbital magnetic resonance imaging revealed hyperintensity on diffusion-weighted imaging of the left optic nerve, with corresponding low signal on apparent diffusion coefficient maps, suggestive of acute infarction of the left optic nerve. Combined with the patient's cranial magnetic resonance imaging findings, the diagnosis of cavernous sinus syndrome was established...

From the time of Hippocrates to the early 19th century, knowledge advanced but that was an uneven process. Anatomy was basically defined by Galen and remained cast in stone until the early 16th century. Neuroanatomy was described by Galen but had little practical value, as brain surgery was not possible. The anatomy of the cranium was known and was largely correct. Care was taken to avoid the frontal air sinuses and the venous sinuses and the temporal region. The role of the brain in consciousness was not understood...

Cranial sutures are not of great concern to the modern neurosurgeon, except when abnormalities interfere with the skull's shape and its ability to expand during childhood. It is a commonplace that a craniotomy may cross a variety of sutures without providing any extra difficulty to the operator. The sagittal suture does remain useful as a definition of the midline of the cranium and as an indicator of the underlying sinus. Galen for reasons that are far from clear, "observed" relationships between the sutures, the meninges and the pericranium which led him to advise avoidance of any surgical proximity to the sutures...

OBJECTIVES: There is a lack of high-quality data informing the optimal antithrombotic drug strategy following bioprosthetic heart valve replacement or valve repair. Disparity in recommendations from international guidelines reflects this. This study aimed to document current patterns of antithrombotic prescribing after heart valve surgery in the UK. METHODS: All UK consultant cardiac surgeons were e-mailed a custom-designed survey. The use of oral anticoagulant (OAC) and/or antiplatelet drugs following bioprosthetic aortic (AVR) or mitral valve replacement (MVR), or mitral valve repair (MVrep), for patients in sinus rhythm, without additional indications for antithrombotic medication, was assessed...

INTRODUCTION: Orthognathic surgery can lead to sinus alterations, including sinusitis, attributed to the exposure of maxillary sinuses during Le Fort I osteotomy. Furthermore, being a hospital-based procedure, there is potential risk of complications arising from bacteria prevalent in such environments. This study evaluated maxillary sinusitis occurrence and the presence of multidrug-resistant bacteria in the nasal cavity before and after orthognathic surgery. METHODS: Ten patients with dentofacial deformities underwent Le Fort I osteotomy...

Laser surgery, a minimally invasive procedure for the definitive approach to pilonidal disease (PD), has been frequently studied in recent years. This study aims to describe a new pilonidotomy method using minimal laser energy and evaluate its initial results. This is a retrospective multicenter study. We included 47 consecutive patients who underwent 50 "minimal energy pilonidotomies (MELPi)" between 2019 and 2023 in four centers in Brazil. Age, BMI, gender, smoking, diabetes, Guner classification, duration of illness, energy, hospitalization time, complications, recurrence, wound closure, pain, and return to activities were analyzed...

Endoscopic middle meatal antrostomy (MMA) is commonly used for maxillary sinus (MS) fungal ball removal. For challenging cases involving anterior or inferior recess, an additional inferior meatal approach (IMA) might be needed. We analyzed the differences in MS dimensions on CT scans according to the surgical approach to suggest preoperative variables that could facilitate an additional IMA. CT scans of 281 adult patients who underwent ESS for the MS fungal ball (139 MMA, 62 MMA & IMA) were evaluated for comparative analysis of 8 MS measurements based on the surgical approach...

Endoscopic surgery is an effective and common clinical practice for chronic sinusitis. Nasal packing materials are applied in nasal surgery to prevent hemorrhage and promote wound healing. In this study, a degradable polyurethane foam dressing is successfully developed as a promising nasal packing material with good biocompatibility and antibacterial capability. Specifically, quaternized chitosan (QCS) serves as the crosslinker instead of polyols to offer polyurethane foam (PUF-QCS) antibacterial capability...

Females are at higher risk than males for a multitude of cerebrovascular conditions, both common and rare; partially resulting from a complex interplay between differing process involving genetics, hormonal influences, common cerebrovascular risk factors among others. Specific topics including cervical artery dissection, cerebral dural sinus venous thrombosis, reversible cerebral vasoconstriction syndrome, migraine, along with these disorders in the setting of pregnancy, puerperium and oral contraceptive utilization...

OBJECTIVES: To characterize the diagnosis, frequency, and procedural implications of septal venous channel perforation during left bundle branch area pacing (LBBAP). METHODS: All consecutive patients undergoing LBBAP over an 8-month period were prospectively studied. During lead placement, obligatory septal contrast injection was performed twice, at initiation (implant entry zone) and completion (fixation zone). An intuitive fluoroscopic schema using orthogonal views (LAO/RAO) and familiar landmarks is described...

Unroofed sinus is categorized into four subtypes. Types I and II represent complete unroofing with or without an LSVC, respectively [1]. Types III and IV are partial unroofing involving the mid-CS (type III) or near the LA appendage and left superior pulmonary vein (type IV) [1]. CT has advantages over echocardiography in detection of this anomaly (illustrated in this case) as well as in precise delineation of defect and associated findings (presence or absence of LSVC). Short axis reconstructions at the level of CS are helpful in diagnosis...

BACKGROUND: Prediction of drug-induced long QT syndrome (diLQTS) is of critical importance given its association with torsades de pointes. There is no reliable method for the outpatient prediction of diLQTS. OBJECTIVES: This study sought to evaluate the use of a convolutional neural network (CNN) applied to electrocardiograms (ECGs) to predict diLQTS in an outpatient population. METHODS: We identified all adult outpatients newly prescribed a QT-prolonging medication between January 1, 2003, and March 31, 2022, who had a 12-lead sinus ECG in the preceding 6 months...
