BACKGROUND AND OBJECTIVES: Body lateropulsion with falling to one side is a well-known clinical feature of stroke in the posterior circulation. Body lateropulsion as an isolated or predominant manifestation of a pontine stroke has not previously been reported. To elucidate the possible mechanisms of patients presenting with body lateropulsion as an isolated or predominant symptom of isolated pontine infarction. MATERIALS AND METHOD: Between May 2004 and February 2006, out of 134 admitted patients with an isolated pontine stroke we identified 8 consecutive patients (6.0%) in the Keimyung University Stroke Registry who had body lateropulsion as the main presenting symptom. RESULTS: All lesions were localized to the paramedian tegmentum just ventral to the 4th ventricle. All except 1showed a uniform pattern of body lateropulsion, in which the direction of falling was away from the side of infarct. In 2 patients, body lateropulsion was the sole clinical manifestation, whereas the other patients had other neurological signs. All but 1 had contraversive tilting of the subjective visual vertical (SVV). In all cases, the direction of SVV tilt corresponded to the direction of body lateropulsion. The mean net tilt angle was 6.1 CONCLUSION: Based on the known anatomy of ascending vestibular pathways, the SVV tilting, and MRI findings, body lateropulsion probably results from damage to the graviceptive pathway ascending through paramedian pontine tegmentum.

Cerebral venous infarction is associated with a wide variety of clinical symptoms and signs, which may often delay appropriate diagnosis. Unilateral vestibular deficit as a presenting sign of cerebral venous infarction has rarely been reported. We report a patient with cerebral venous infarction who had severe prolonged vertigo, vomiting, occipital headache, positive head thrust testing, and unilateral caloric weakness as main clinical features. Although the patient had occipital headache, overall symptoms and signs closely mimicked those of acute peripheral vestibulopathy.

Vestibular neuritis (VN) is an idiopathic peripheral vestibular syndrome characterized by acute isolated prolonged vertigo. In most cases, it results from inflammation of the vestibular nerve presumably of viral origin. There has been no previous report of VN associated with a vascular cause. We here report a patient with VN of vascular origin who presented with acute onset of prolonged isolated vertigo, a unilateral decreased caloric response, and simultaneously with acute infarcts on brain MRI that were unrelated to patient's vertigo.

The clinical studies were performen on 304 patients with heart disease who had been received corrective heart surgery at Kosin Medical Center from July, 1984 to December, 1991. The results were as follows: 1) Out of 304 patients, 162 cases (53.3%) were male and 142 cases (46.7%) were female and sex ratio was 1.15:1. 35 cases (11.5%) had clinical cyanosis and 269 cases (88.5%) had no evidence of cyanosis. 2) As age distribution of patients, under 2 years, 3~5 years, 6~10 years, 11~15 years, 16~18 years consist of 22.0%, 26.0%, 29.0%, 16.1% and 6.9%, respectively. 3) As disease distribution, out 304 patients, ventricular septal defect (57.9% of all) was the most common disease, and then atrial septal defect (13.2%), tetralogy of Fallot (11.2%), patent ductus arteriosus (9.9%) and pulmonic stenosis (5.3%), in their order. 4) As sex distribution of each disease, ventricular septal defect, atrial septal defect and tetralogy of Fallot were more common in male and patent ductus arteriosus and pulmonic stenosis were more common in female. 5) The most frequent cardiac anomaly associated with ventricular septal defect and atrial septal defect was pulmonic stenosis. In the case of subarterial ventricular septal defect, aortic insufficiency was associated in 13.3%. 6) Respiratory problems (11.3%), tricuspid regurgitation (9.5%), arrhythmia (6.2%) and congestive heart failure (5.8%) were the major complications after surgery. 7) Case fatality reat was 4.4%. Mortality rate in ventricular septal defect, tetralogy of Fallot and tricuspid atresia were 1.7%, 20.6% and 100%, respectively, Majority (75.0%) of expired patients were died within 24 hours after sugery and the cause of death was hypoxia due to low cardiac output syndrome.

Journal of the Korean Neurological Association 2024;42(2):116-125
Background:
To investigate the patterns of blood pressure (BP) decrement during the tilt, to compare the pattern of orthostatic hypotension (OH) and sympathetic index (SI) from the Valsalva maneuver (VM), and to identify whether the pattern of OH can predict the severity of autonomic failure.
Methods:
From January 2015 to July 2017, 551 consecutive patients with neurogenic OH were enrolled. All patients performed a standardized battery of autonomic tests, including the head-up tilt (HUT) test and VM using Finometer devices for recording beat-to-beat BP. SIs were calculated from the VM. The composite autonomic severity score (CASS) adrenergic subscore was also obtained to evaluate the severity of sympathetic adrenergic failure.
Results:
We classified OH into nine groups according to the patterns of orthostatic BP decrement during HUT. The two most common patterns of OH were classic stable OH (n=193) and classic OH with delayed normalization (n=102). Patients with classic stable OH and classic OH with delayed worsening had a more severe degree of sympathetic adrenergic failure as assessed with SI 5 and SI 4 from the VM, and a higher CASS adrenergic subscore than patients with other patterns of OH. There were no differences of autonomic parameters between the two delayed OH groups.
Conclusions
The different patterns of orthostatic BP decrement may reflect underlying different pathophysiologic mechanisms causing OH. The pattern of orthostatic BP decrement can help to predict the degree of sympathetic adrenergic autonomic failure.

10.Recent Advances in Understanding Audiovestibular Loss of a Vascular Cause.
Journal of Stroke 2017;19(1):61-66
Acute audiovestibular loss is characterized by abrupt onset of prolonged (lasting days) vertigo and hearing loss. Acute ischemic stroke in the distribution of the anterior inferior cerebellar artery (AICA) is known to be the leading cause of acute audiovestibular loss. So far, eight subgroups of AICA territory infarction have been identified according to the patterns of audiovestibular dysfunctions, among which the most common pattern is the combined loss of auditory and vestibular functions. Unlike inner ear dysfunction of a viral cause, which can commonly present as an isolated vestibular (i.e., vestibular neuritis) or cochlear loss (i.e., sudden deafness), labyrinthine dysfunction of a vascular cause rarely results in isolated loss of vestibular or auditory function. As audiovestibular loss may precede the central symptoms or signs of an ischemic stroke in the posterior circulation, early diagnosis and proper management of audiovestiubular loss may provide a window to prevent the progression of infarction to larger areas of the posterior circulation. A clinician should consider the possibility that acute audiovestibular loss may herald impending AICA territory infarction, especially when patients have basilar artery occlusive disease close to the origin of the AICA on brain MRA. This review aims to highlight the recent advances in understanding audiovestibular loss of a vascular cause and to address its clinical significance.
