Life-threatening complications like cardiac tamponade exist. Intracardiac echocardiography (ICE) usage is associated with superior safety in radiofrequency ablation.

Olfactory schwannomas - an enigmatic clinical entity.

Olfactory Schwannomas (OS) are a rare, benign tumour entity. Throughout literature, only few cases have been reported. We describe here a case of a 75-year-old female with a contrast enhanced mass lesion in the anterior fossa, who underwent a surgical removal and its histopathological analysis was consistent with a schwannoma.

Carboxytherapy in dermatology.

Carboxytherapy is a medical technique during which a sterile gas-carbon dioxide-is injected into the subdermal tissue. The utility of carbon dioxide injections has enhanced the practical relevance of carboxytherapy as a method for the management of multiple disorders. We have evaluated its use in the treatment of dermatologic conditions by searching electronic databases (ie, MEDLINE and PubMed) for contributions in the English language through January 2021.

Catheter Ablation in Complex Atrial Arrhythmias: Pilot Study Evaluating a 3D Wide-Band Dielectric Imaging System.

Background: Cryoballoon ablation (CBA) for pulmonary vein isolation (PVI) is a standard in atrial fibrillation (AF) ablation but might not be enough in complex atrial arrhythmias (AA). An open three-dimensional wide-band dielectric imaging system (3D-WBDIS) has been introduced to guide CBA.

Material And Methods: Pilot study evaluating feasibility and safety of 3D-WBDIS in combination with CBA and optional radiofrequency ablation (RFA) in patients with complex AA defined as (1) history of persistent AF, (2) additional atrial tachycardia/flutter, or (3) previous left atrial ablation.

Rare osteoarticular complications on [18F]FDG-PET/CT - following intravesical BCG immunotherapy for bladder cancer.

This case illustrates rare osteoarticular complications of Bacillus Calmette-Guérin (BCG) immunotherapy in a 55-year-old male with high-risk non-muscle-invasive bladder cancer (NMIBC). The patient was referred for 18F-fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) to rule out bone metastases suspected on prior post-gadolinium magnetic resonance imaging (MRI). Although metastases were excluded, nearly symmetrical uptakes were detected in the costovertebral and costotransverse joints.

Biologic and targeted therapeutics in vitiligo.

Background: Vitiligo is a long-standing progressive autoimmune disease with depigmented macules/patches with significant psychological morbidity to the patients. From being one of the most poorly understood diseases in the past, there has been a rampant advance in determining the molecular and genetic factors influencing the disease process. More light has been shed on the complex intracellular environment and interplay between innate and adaptive immunity.

Cryoballoon Ablation Strategy in Persistent Atrial Fibrillation.

Cryoballoon ablation is established for pulmonary vein isolation (PVI) in paroxysmal atrial fibrillation (AF). The objective was to evaluate CBA strategy in consecutive patients with persistent AF in the initial AF ablation procedure. Prospectively, patients with symptomatic persistent AF scheduled for AF ablation all underwent cryoballoon PVI.

Risk of Upstaging Due to Oncofertility Treatment Mimicking Pelvic Lymphoma on 18F-FDG PET/CT.

A 23-year-old woman with primary mediastinal large B-cell lymphoma was referred to 18F-FDG PET/CT for staging. Besides the large mediastinal FDG-avid tumor, another FDG-avid lesion with an SUV higher than expected in corpus luteum cysts was found in the pelvis, raising suspicion for tumor. However, gynecologic ultrasound and review of patient chart revealed history of oncofertility treatment with GNRH analog.

New diagnostic and imaging technologies in dermatology.

Introduction: Diagnosis of dermatological disorders is primarily based on clinical examination in combination with histopathology. However, clinical findings alone may not be sufficient for accurate diagnosis and cutaneous biopsies are being associated with morbidity.

Objective: The objective of this article is to review the newer technologies along with their applications, limitation and future prospectus.

Cardiac computed tomography angiography-derived analysis of left atrial appendage morphology and left atrial dimensions for the prediction of atrial fibrillation recurrence after pulmonary vein isolation.

Background: Left atrial appendage (LAA) is a potential source of atrial fibrillation (AF) triggers.

Hypothesis: LAA morphology and dimensions are associated with AF recurrence after pulmonary vein isolation (PVI).

Methods: From cardiac computed tomography angiography (CCTA), left atrial (LA), pulmonary vein (PV), and LAA anatomy were assessed in cryoballoon ablation (CBA) patients.

Pustular psoriasis flare-up in a patient with COVID-19.
