Clinical Characteristics and Risk Factors for the Recurrence of Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo (BPPV) manifests itself as a paroxysm of vertigo and nystagmus lasting several seconds, which is self-limiting. The clinical characteristics and risk factors for the recurrence of BPPV in different ages have not yet been investigated.Materials and Methods: A retrospective observational study was conducted in the Department of Neurology in Beijing Tiantan Hospital from July 2009 to June 2015. The study included 1,012 patients aged 18–93 years. All patients received the definitive diagnosis and canalith repositioning maneuvers treatment and finally accomplished follow-up. Demographic variables, potential recurrence risk factors, neurological examination, and laboratory indexes were assessed.Data Analyses: The t-test or chi-squared test was first performed for group comparison, then logistic regression analysis was used to investigate the risk factors of BPPV recurrence.Results: The 1-year recurrence rates of BPPV patients after reposition maneuvers were, respectively, 22.79% (aged 18–45 years), 23.92% (aged 45–60 years), 28.89% (over 60 years). The recurrence rates among the three groups have no statistically significant difference. Logistic regression analysis shows that women BPPV patients have more recurrence risks than do men. Ménière's disease (odds ratio = 6.009, 95% confidence interval: 2.489–14.507, p

Headache is the third leading cause of referral to pediatric emergency departments (ED). Based on a systematic review, headaches in children evaluated in the ED are primarily due to benign conditions that tend to be self-limiting or resolve with appropriate pharmacological treatment. The causes of non-traumatic headache in the ED include more frequently primitive headaches (21.8-66.3%) and benign secondary headaches (35.4-63.2%), whereas potentially life-threatening (LT) secondary headaches are less frequent (2 to 15.3%). Worrying conditions include brain tumors, central nervous system infections, dysfunction of ventricu...

This report has basically focused on scleroderma renal crisis (SRC), which is the most serious renal manifestation of SSc, characterized by renal failure and sudden onset of hypertension. A 44-year-old man was hospitalized with hypertension, headache, vertigo, nausea, rhinorrhea, reflux, dysphagia, dyspnea (Fc II), visual impairment, mechanical arthralgia, and edema (+3) accompanied by a rare skin lesion. Raynaud's phenomenon was also remarkable in fingers and toes. According to signs and symptoms, SSc diagnosed and the proper treatment was applied. It is of great importance that in the case of malignant hypertension in pa...

CONCLUSIONS: There seem to be no major differences in the structure, early diagnostic approach and management of ACE mimics between referrals from ambulance physicians and ambulance paramedics, which provides reassurance to the healthcare systems that rely solely on paramedics. Mimics referred by non-ambulance physicians appear different in structure and less resource consuming. PMID: 30614515 [PubMed - as supplied by publisher]

Migraine is a common medical condition, affecting as many as 37 million people in the US. It is considered a systemic illness, not just a headache. Recent research has demonstrated that changes may begin to occur in the brain as long as 24 hours before migraine symptoms begin. Many patients have a severe throbbing headache, often on only one side of the head. Some people are nauseated with vomiting. Many are light sensitive (photophobic) and sound sensitive (phonophobic), and these symptoms can persist after the pain goes away. There are a variety of migraine subtypes with symptoms that include weakness, numbness, visual c...

Cerebellar strokes account for less than 10% of all strokes but lead to significantly poor outcomes. Cerebellar strokes that are initially missed have a mortality rate of 40%, and half of the patients who survive have long-term deficits. The patient's history may provide clues that point to a cerebellar stroke. Signs and symptoms include vertigo, headache, vomiting and ataxia. It is important to note the presence of stroke risk factors, such as a history of strokes or transient ischemic attacks, diabetes mellitus, hypertension, hypercholesterolemia, advanced age, atrial fibrillation, and cigarette smoking. The importance o...

Conclusions:Increased PWV values were detected in patients with dizziness or vertigo due to stroke. PWV value may be used as a predictor of central vertigo even though there should be more convincing evidences.Disclosure: Dr. Cho has nothing to disclose. Dr. Kim has nothing to disclose.
