Syncope associated with the act of swallowing (deglutition syncope) and syncope associated with head and neck cancers have been documented independently. We present a case of syncope precipitated by a combination of both these mechanisms. It is important to recognize the coexistence of different hemodynamically significant mechanisms leading to syncope. A 66-year-old male recently diagnosed with head and neck cancer presented with syncope associated with eating. Diagnosis was complicated because of multiple factors in this patient, which individually could have led to syncope.

Syncope is a frequent symptom in older patients. The diagnostic and therapeutic management may be complex, particularly in older adults with syncope and comorbidities or cognitive impairment. Morbidity related to syncope is more common in older persons and ranges from loss of confidence, depressive illness and fear of falling, to fractures and consequent institutionalization. Moreover, advan-ced age is associated with short and long-term morbidity and mortality after syncope.

BACKGROUND: Neurally mediated reflex syncope is the most common cause of transient loss of consciousness. In patients not responding to non-pharmacological treatment, pharmacological or pacemaker treatment might be considered. OBJECTIVES: To examine the effects of pharmacological therapy and pacemaker implantation in patients with vasovagal syncope, carotid sinus syncope and situational syncope.

Vasovagal syncope (VVS) and carotid sinus syndrome (CSS) are related, neurally mediated disorders with different clinical features and treatment implications. Pacemaker intervention studies in both syndromes are hampered by a dearth of randomized, controlled (particularly with placebo) studies, unfortunate premature termination of studies, and variation in both the clinical presentation and cardiovascular profile of patients enrolled.

BACKGROUND AND AIMS: Vasodepressive carotid sinus hypersensitivity (V-CSH) is a common but incurable etiology for fainting in older adults with diabetes (OADM), and is diagnosed by carotid sinus massage (CSM). Aerobic exercise has been shown to be an effective therapy for other neuroautonomic etiologies of syncope (such as orthostatic hypotension), but the effectiveness of aerobic training in V-CSH remains unknown. We examined whether aerobic training could attenuate the vasodepressive response to CSM in OADM (older adults with type 2 diabetes) subjects complicated by V-CSH.

OBJECTIVE: To assess treatment with fludrocortisone in vasodepressor carotid sinus syndrome. PATIENTS AND METHODS: Eleven patients, mean (SD) age 83 (5) years, with daily dizzy episodes and a median of five (range two to 20) syncopal episodes over a median of one year were studied. All had vasodepressor carotid sinus syndrome (> 50 mm Hg fall in systolic blood pressure during carotid sinus massage independent of bradycardia). Carotid sinus massage was carried out while the patient was supine and upright (tilt table) before and after 600 micrograms intravenous atropine.

Lavender plants have been used for their cosmetic and biologic benefits for many centries. Extracts from Lavandula plants have been found to cause antimuscarinic effects by blocking sodium and calcium ion channels in in vitro and in vivo studies. We present a case of poisoning by ingestion of tea made from Lavender stoechas ( grass). The patient was admitted to our emergency department with supraventricular tachycardia due to anticholinergic syndrome triggered by drinking lavender tea. On electrocardiography, a narrow QRS complex tachycardia was evident.
