Postural orthostatic tachycardia syndrome (POTS) refers to the presence of orthostatic intolerance with a heart rate (HR) increment of 30 beats per minute (bpm) or an absolute HR of 120 bpm or more. There are sporadic reports of the autonomic nervous system dysfunction in migraine and fibromyalgia. We report a case of POTS associated with migraine and fibromyalgia. The patient was managed with multidisciplinary therapies involving medication, education, and exercise which resulted in symptomatic improvement. We also review the literature on the association between POTS, migraine, and fibromyalgia.

Fibromyalgia is a chronic pain syndrome of unknown etiology that is characterized by diffuse musculoskeletal pain, fatigue, sleep disturbance, memory disturbance, and exaggerated tenderness over particular paired locations. Fibromyalgia is found in 2% to 4% of the general population and more common in women, with symptoms usually appearing between 20 and 55 years of age. The diagnostic criteria for fibromyalgia syndrome established in 1990 by the American College of Rheumatology (ACR), includes widespread pain for at least 3 months and point tenderness upon the application of a 4 kg weight at 11 or more of the 18 characteristic tender points. The 2010 ACR preliminary diagnostic criteria have been developed, which are strongly correlated with the 1990 ACR criteria and provide an alternative approach to diagnosis. Patients with fibromyalgia syndrome have lower pain thresholds and experience an altered temporal summation to pain stimuli. The sensitization of pain perception occurs in the dorsal horn of patients with fibromyalgia. However, it is unknown whether sensitization is due to increased pain fiber facilitation, or decreased inhibition. Pregabalin is approved by the United States Food and Drug Administration for the management of fibromyalgia patients. Tricyclic antidepressants, cardiovascular exercise, cognitive behavioral therapy and patient education are also effective in reducing the pain experienced by fibromyalgia patients. This article provides an overview of fibromyalgia syndrome, which is currently thought to be partly responsible for chronic diffuse pain.

We reviewed 27 patients wlth cerebellar infarction which was demonstrated by brain CT and/or MRI. Infarction occurred in the territory of posterior inferior cerebellar artery (PICAj in 16 patients, and the territory of the superior cerebellar artery(SCA) was involved in 5 patients. Antenor inferior cerebellar artery(AICA) infarcts occurred in 3 patients. Both PICA and SCA temtories were involved in 2 patients. In the remaining 1 patient, the infarct encompassed the borderzone between the SCA and PICA territories. The main symptoms and signs were sudden onset of vertigo, dizziness, nausea, vomiting, dysmetria, ataxia, nystagmus, and headache. There were signs of associated brain stem infarction or occipitotemporal infarction; rostral basilar artery syndrome, classic SCA syndrome, Wallenberg syndrome, internuclear ophthalmoplegia, facial palsy, hearing impairment. Presumed cerebral embolism was the main stroke mechanism in the SCA terntories. Six patients with brainstem compression or brainstem involvement showed consciousness deterioration, and only one of them died as a result of extensive cerebellar infarctions involving both SCA and PICA territories Cerebellar infarction may run a more benign course than previously thought.

BACKGROUND: Memory impairment results from various neurologic disorders. Among them, the memory loss associated with stroke is called amnesic stroke. Involved regions in the amnesic stroke are medial temporal lobe, thalamus, basal forebrain, retrosplenial region, and subcortical regions. Unilateral amnesic stroke is posterior cerebral artery territory including thalamus. Isolated infarction of hippocampal region has been rarely reported because hippocampus has dual blood supply from anterior choroidal cerebral artery and posterior cerebral artery. CASE REPORT: A 61-year old male with a history of diabetes for 6 years and hypertension for 13 years, was admitted with acute memory loss occurring 6 days before admission. He could not remember the exact date, place and recent events but could remember remote events about his personal and familial affairs. Brain MRI revealed an infarction in left hippocampal region and cerebral angiography showed multiple focal stenosis and luminal irregularity on left anterior choroidal, middle cerebral, basilar and both posterior cerebral arteries. COMMENTS: We report unilateral amnesic stroke only confined to left hippocampal region with literature review.

The binding of anti-GD1b IgG antibody to the cerebellar granular area or spinocerebellar Ia fibers in the peripheral nerves may cause the prominent cerebellar ataxia, mild quadriparesis and sensory dominant neuropathy. A 31-year woman presented with severe cerebellar ataxia and prominent apogeotropic positional nystagmus/vertigo. Increased anti-GD1b antibody IgG in her serum was noted. 18F-flurodeoxyglucose positron emission tomography (FDG-PET) showed decreased uptake in cerebellum. It is the first case of central positional nystagmus with anti-GD1b IgG antibody.

BACKGROUND: Intracranial complications of paranasal sinus infection are rare and may be misdiagnosed during an initial evaluation because they often show subtle symptoms, which include elusive physical and neurological findings and imaging. The late recognition of these conditions and the delayed treatment can increase morbidity and mortality rates. We aimed to characterize the typical clinical features of intracranial complications associated with sinusitis. METHODS: Twelve patients who visited the Eulji Medical Center from 1994 to 2000, with sinogenic suppurative intracranial lesions were reviewed. Medical records and radiological studies were reviewed retrospectively. RESULTS: There were 12 cases with 15 sinogenic intracranial complications. The ratio of males to female was 2 : 1. The ages of patients ranged from 16 to 81 (average: 46.7). Four cases had meningitis, four had focal cerebritis, three had cavernous sinus throm-bophlebitis, two had subdural empyema, and two had epidural abscess or empyema. The primary lesions of paranasal sinusitis were located at the sphenoid in three, ethmoid sinus in two, frontal sinus in one and the multiple sinus in six. The outcome revealed complete recovery in six cases, mild neurologic sequelae in three cases, death in two cases and recurrence in one case. CONCLUSIONS: The type of intracranial complication and origin of paranasal sinusitis may be changing. Cases in which such complications are suspected, in order for an early diagnosis, a MRI should be considered. The successful management of intracranial complications consists of timely antibiotics therapy combined with surgical drainage of the loculated infection. (J Korean Neurol Assoc 19(5):457~463, 2001)

We report unusual MRI findings (including those from diffusion-weighted imaging (DWI)) in a patient with recurrent Wernicke's encephalopathy with a remarkable cerebellar lesion. DWI showed high signal intensities in the superior portion of the cerebellar hemisphere and vermis area. After thiamine administration, clinical symptoms improved and the lesions with high signal intensities disappeared on follow-up DWI.

A 59-year-old man was admitted because of progressive proximal muscle weakness over 4 months. Serum creatine kinase was markedly increased and electromyography revealed myopathic pattern. Muscle biopsy showed nonspecific myopathic changes. No inflammatory change was shown. Thyroid function tests revealed very low thyroxine and low triiodo-L-thyronine, whereas thyroid-stimulating hormone was greatly increased as well as serum anti-thyroglobulin and microsome antibodies. The patient had hypothyroid myopathy due to Hashimoto's thyroiditis, which improved with L-thyroxine replacement.
