Dizziness is a common and challenging symptom, which can be caused by different pathophysiological mechanisms and might affect a large number of population. However, up to now, there have been limited research on the characteristics of dizziness as the chief complaint in hospitalized patients in the Department of Neurology. Thus, the aim of this study was to investigate the hospitalized patients with dizziness as their chief complaint in the Department of Neurology.In this cross-sectional study, we conducted a retrospective document analysis of hospitalized patients admitted to a tertiary neurological department with the symptom of dizziness during the period of September 2019 to December 2020. We included 211 patients with dizziness as their chief complaint from 1841 patients admitted to this tertiary neurological department during that period.Of all 1841 hospitalized patients, those with dizziness as the chief complaint accounted for 11.5% and most of their past medical history included hypertension, diabetes, cerebrovascular diseases, dyslipidemia, and coronary heart disease. Among these 211 patients, dizziness was more common in women than in men (p = .004). More patients presented with vertigo (40.8%) and light-headedness (39.8%) than disequilibrium (17.1%) and pre-syncope (2.4%). Nausea (48.3%), vomiting (34.1%), headache (13.3%), walking unsteadily (13.3%), and ear symptoms (12.8%) were the most common concomitant symptoms. Dix-Hallpike test (24.6%) and Romberg's sign (11.4%) were positive in these dizzy patients. Nystagmus (2.4%), vision changes (1.4%), and hearing disorders (8.5%) were relatively rare symptoms. Common auxiliary examinations were performed, such as magnetic resonance imaging (60.2%), computed tomography (31.8%), carotid duplex ultrasound (30.8%), and echocardiography (28.0%). Benign paroxysmal positional vertigo (24.2%) and stroke/transient ischemic attack (19.0%) were confirmed to be common causes of dizziness. Note that 97.2% of dizzy patients were in improved recovery after treatment.The diagnosis and management of dizziness remain a challenge for clinicians. Vertigo and light-headedness were the most common symptoms among different types of dizziness. Benign paroxysmal positional vertigo and stroke/transient ischemic attack were among the leading causes for common dizziness disorders. The prognosis of most dizzy patients was good.

Background Dizziness is a common and challenging condition among population. There is little published study which surveys the characteristics of dizziness of inpatients in the department of neurology. Objective This study was to investigate the inpatients with dizziness as the chief complaint in a neurology department. Materials and Methods We conducted a retrospective study of inpatients with dizziness attending a tertiary neurological department in Beijing. We audited 211 patients with dizziness as the chief complaint from 1841 patients discharged from our tertiary neurological department. Results The inpatients with dizziness as the chief complaint accounted for 11.5% of all inpatients. Dizziness was more common in women than in men (p=0.004). There were more patients presenting with vertigo (40.8%) and light-headedness (39.8%) than disequilibrium (17.1%) and pre-syncope (2.4%). Nausea (48.3%), vomiting (34.1%), headache (13.3%), walk unsteadily (13.3%) and ear symptoms (12.8%) were the most common accompanying symptoms. Hypertension, diabetes, cerebrovascular diseases, dyslipidemia, and coronary heart disease were the most common diseases in past medical history. Dix-Hallpike test (24.6%) and Romberg’s sign (11.4%) were positive in dizziness patients. Nystagmus (2.4%), vision changes (1.4%) and hearing disorders (8.5%) were relatively rare symptoms. MRI (60.2%), CT (31.8%), carotid duplex ultrasound (30.8%), echocardiography (28.0%) were common auxiliary examination. Benign paroxysmal positional vertigo (24.2%) and stroke/transient ischemic attack (19.0%) were common causes of dizziness. 97.2% of inpatients with dizziness can be improving after treatment. Conclusion Dizziness was a common and challenging condition. Vertigo and light-headedness were the most common dizziness types. Benign paroxysmal positional vertigo and stroke/transient ischemic attack were the common dizziness disorders. The prognosis of most patients with dizziness was good.

Vestibular migraine (VM) is considered the most common cause of spontaneous episodic vertigo and the second most common cause of vertigo. However, without a biomarker or a complete understanding of the pathophysiology, VM remains underrecognized and underdiagnosed. Therefore, definite diagnostic criteria are urgently needed. Meanwhile, VM should be clearly differentiated from other similar diseases. This paper may help clinicians improve the diagnostic rate of VM and reduce the rate of misdiagnosis. A PubMed search was performed using the following terms: vestibular migraine, migraine-associated vertigo/dizziness, migraine-related vertigo, migraine-related vestibulopathy, benign recurrent vertigo, vertiginous migraine, migraine, headache, vertigo, dizziness, and diagnosis. This paper also summarizes the diagnostic criteria and differential diagnoses of VM. The diagnosis of VM is based on the symptoms, degree, frequency, and duration of the vestibular episodes, a history of migraine, and the temporal association of migraine symptoms with vestibular episodes in at least 50% of cases, while ruling out what may be due to other reasons. In addition to vestibular symptoms and migraine, transient auditory symptoms, nausea, vomiting, and susceptibility to motion sickness may also be associated with VM. Thus, VM should be differentiated from other diseases such as Meniere's disease, benign paroxysmal positional vertigo, migraine with brainstem aura, vestibular neuritis, posterior circulation ischemia, multiple lacunar infarction, vestibular paroxysmia, motion sickness, and episodic ataxia type 2.Only if the diagnostic criteria of VM and differential diagnosis can be mastered clearly, we can make a definite diagnosis and treat patients properly.

Purpose. A case of autoimmune hemolytic anemia (AIHA) after treatment with a Chinese herbal preparation is reported. Summary. A 29-year-old woman was admitted to the hospital with the primary complaints of jaundice, tea-colored urine, and fatigue lasting 10 days. Thirteen days prior, she went to a local private clinic seeking treatment for mild stomach pain and general malaise and was given weidean tablets. She took four tablets of weidean, a Chinese herbal preparation, orally three times daily for 2 days. After 2 days, she experienced fatigue, dizziness, and chest distress and subsequently discontinued treatment. Upon examination, she exhibited mild scleral and mucosal icterus. Her conjunctivas were pale, and her skin was slightly jaundiced. Preliminary laboratory tests found a low hemoglobin level and an elevated reticulocyte count. Biochemical tests showed an elevated total serum bilirubin concentration with indirect hyperbilirubinemia. Coombs’ test results were positive for immunoglobulin G but negative for C3. All other test results were normal. The patient was diagnosed with AIHA secondary to weidean use, and she was treated promptly with oral prednisone, i.v. cimetidine, and oral sodium bicarbonate tablets. Seven days later, she showed clinical improvement. Her hemoglobin level rapidly increased to above 100 g/L, with a corresponding decrease in her reticulocyte count and serum bilirubin value over the next 8 days. She was discharged 15 days after admission and was asymptomatic at a three-week follow-up visit. Conclusion. Weidean, a formulation of Chinese medicinal herbs and other constituents, was associated with AIHA in a woman taking the remedy for gastritis.
