Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial...

Electronic cigarettes are increasingly popular as a supposed safer alternative to tobacco cigarettes or a smoking cessation tool. Research and debate have focused primarily on possible adverse effects caused by the inhaled aerosol produced by electronic cigarettes and on smoking cessation efficacy. Few reports in the medical literature describe injuries secondary to device malfunction. We present a case of electronic cigarette explosion, with a projectile fracturing the patient's right naso-orbital-ethmoid complex and anterior and posterior frontal sinus tables, with frontal sinus outflow tract involvement...

OBJECTIVES: Carotid baroreflex plays a crucial role in regulating arterial pressure. Based on this knowledge, electrical stimulation of carotid sinus was designed for treating resistant hypertension. However, the clinical implication of electrical stimulation of carotid sinus is largely restrained due to obvious invasiveness. This study aimed to evaluate the efficacy of magnetic stimulation of carotid sinus (MSCS), a noninvasive strategy, for lowering blood pressure in rabbits. METHODS: MSCS with graded intensities and frequencies were systematically attempted in normotensive rabbits...

BACKGROUND: Sinus bradycardia includes pathologic sick sinus syndrome (SSS) and physiologic bradycardia such as athletes' heart. Pacemaker implantation is indicated for patients with symptomatic SSS; however, the indication remains difficult to determine in those with mild and/or unspecific symptoms. The sympathetic tone is increased in response to reduced cardiac output in SSS, whereas excessive vagal tone has been seen in physiological bradycardia. We sought to determine if cardiac iodine-123-metaiodobenzylguanidine scintigraphy ((123) I-MIBG) was useful in differentiating pathologic from physiologic sinus bradycardia...

BACKGROUND: Pulmonary vein isolation (PVI) using the 2nd-generation cryoballoon (CB2) for the treatment of atrial fibrillation (AF) has demonstrated encouraging acute and mid-term results. However, follow-up data on outcomes beyond 1 year are sparse. We investigated the 3-year outcome after PVI using the CB2.Methods and Results:100 patients with paroxysmal (PAF, 70/100 [70%] patients) or persistent AF (pAF, 30/100 [30%] patients) underwent CB2-based PVI in 2 experienced centers in Germany...

BACKGROUND: Recent studies have shed light on the continued prescription of inpatient medications upon hospital discharge despite the original intent of short-term inpatient therapy. Amiodarone, an antiarrhythmic associated with significant adverse effects with long-term use, is commonly used for new-onset atrial fibrillation in critical illness (NAFCI). While it is often preferred in this setting of hemodynamic instability, a prescription for long-term use should be carefully considered, preferably by a cardiologist...

Swallow induced syncope is a rare clinical condition which is thought to result from an abnormal vagal reflex leading to bradycardia and cerebral hypoperfusion. It mostly occurs in patients with organic or functional disorders of the esophagus, and often requires permanent pacemaker implantation, along with treatment of the underlying esophageal pathology. In the following case, we report of a 71-year-old male with achalasia post per oral endoscopic myectomy, who presented with syncope and documented AV-block while eating solid food...

We present a case of a 59-year-old man with left upper alveolar numbness of 2 years' duration in the absence of sinonasal symptoms. On physical examination, he demonstrated mild left facial asymmetry and diminished sensation of his left upper alveolus from the left second upper incisor to first canine. CT imaging revealed chronic sinusitis changes of the left maxillary sinus, with reduced volume and depressed anterior wall. The patient underwent functional endoscopic sinus surgery to re-establish maxillary sinus ventilation...

This meta-analysis was designed to determine the effect of an intracardiac lateral tunnel (ILT) versus an extracardiac conduit (ECC) on patients undergoing a Fontan procedure. A search of the literature in PubMed, Embase, China Academic Literature, and Wanfang databases yielded 23 studies comprising approximately 1000 patients for analysis. There were statistically significant differences between ILT and ECC in the frequency of early sinus node dysfunction, early total arrhythmias, late supraventricular tachycardia, late sinus node dysfunction, late total arrhythmias, and need for pacemaker...

Sinusitis is a common disease. Complications, however, are less common and can be life threatening. Major complications occur from extension of disease into the orbit and intracranial compartment and often require emergent treatment with intravenous (IV) antibiotics or operative intervention. Immunocompromised patients with acute sinusitis are susceptible to atypical infections, such as invasive fungal sinusitis, which is a surgical emergency. Therefore, it is important to accurately and promptly identify potentional complications of acute sinusitis to ensure appropriate treatment and minimize negative outcomes...

Common physiological manifestations of cocaine are related to its adrenergic effects, due to inhibition of dopamine and norepinephrine uptake at the postsynaptic terminal. Few studies have documented bradycardia secondary to cocaine use, representing the antithesis of its adrenergic effects. We assessed the prevalence of sinus bradycardia (SB) in habitual cocaine users and postulated a mechanism for this effect. One hundred sixty-two patients with a history of cocaine use were analyzed and compared with age- and gender-matched controls...
