ABSTRACT
Background@#and Purpose Focal cortical dysplasia (FCD) is one of the most common causes of drug-resistant epilepsy, and necessitates a multimodal evaluation to ensure optimal surgical treatment. This study aimed to determine the supportive value of the morphometric analysis program (MAP) in detecting FCD using data from a single institution in Korea. @*Methods@#To develop a standard reference for the MAP, normal-looking MRIs by two scanners that are frequently used in this center were chosen. Patients with drug-resistant epilepsy and FCD after surgery were candidates for the analysis. The three-dimensional T1-weighted MRI scans of the patients were analyzed as test cases using the MAP. @*Results@#The MRI scans of 87 patients were included in the analysis. The radiologist detected abnormal findings correlated with FCD (RAD positive [RAD(+)]) in 34 cases (39.1%), while the MAP could detect FCD in 25.3% of cases. A combination of the MAP (MAP[+] cases) with interpretations by the radiologist increased the detection to 42.5% (37 cases). The lesion detection rate was not different according to the type of reference scanners except in one case. MAP(+)/RAD(-) presented in three cases, all of which had FCD type IIa. The detection rate was slightly higher using the same kind of scanner as a reference, but not significantly (35.0% vs. 22.4% p=0.26). @*Conclusions@#The results of postprocessing in the MAP for detecting FCD did not depend on the type of reference scanner, and the MAP was the strongest in detecting FCD IIa. We suggested that the MAP could be widely utilized without developing institutional standards and could become an effective tool for detecting FCD lesions.
ABSTRACT
Painful legs and moving toes syndrome (PLMT) is a rare syndrome characterized by pain in the lower extremities and involuntary movements of single or multiple toes. A 29-year-old woman with lumbosacral intervertebral disc herniation complained of bilateral foot pain and involuntary toe movements for three months. This is the first case of PLMT in a young adult patient with a lumbosacral intervertebral disc herniation in Korea.
ABSTRACT
The symptoms of restless legs syndrome (RLS) usually involve legs and can extend to other body parts. However, isolated body parts other than leg have rarely been involved. A 32-year-old woman had abnormal sensations of both forearms and face during night, which caused a difficulty falling in sleep. The symptoms were relieved by shaking and rubbing. She experienced a clear benefit from pramipexole, but a recurrence of restlessness was followed in both arms subsequent to pramipexole withdrawal. Finally, she had been prescribed a dose of 0.375 mg, which was well tolerated for 6 years. We report a case of nocturnal restless arms and face without leg involvement, which was like RLS in terms of clinical criteria except lesion site.

Treatment-induced neuropathy in diabetes (also referred to as insulin neuritis) is considered a rare iatrogenic small fiber neuropathy caused by an abrupt improvement in glycemic control in the setting of chronic hyperglycemia. The prevalence and risk factors are unknown. It presents with neuropathic pain, symptoms of autonomic dysfunction, or a combination of both. We present a case that illustrates the range of presentations of the acute treatment-induced small fiber neuropathy in a patient with diabetes mellitus.

Central pontine myelinolysis (CPM) is well-recognized osmotic demyelination syndrome that is related to various conditions such as rapid correction of hyponatremia and chronic alcoholism. Acute ataxia as a sole clinical sign in CPM is rare. We report a case of a 59-year-old man with dysarthria, intention tremor, and a significant gait ataxia starting after alcohol withdrawal, with radiological evidence of CPM. CPM should be included in the differential diagnosis of alcoholic patients who develop a sudden ataxia. Chronic alcohol abuse is one of the most commonly encountered predisposing factors. Alcohol withdrawal represents an additional vulnerability factor, being responsible for electrolyte imbalances which are not always demonstrable but are certainly involved in the development of CPM.

The symptoms of restless legs syndrome usually involve legs, but can extend to other body parts. However, isolated body parts other than the leg are rarely involved. A 36-year-old woman presented for evaluation with a tingling and burning sensation in the both hands for one year. These abnormal sensations appeared in the evening and night, resulting in difficulty in falling asleep. The symptoms were relieved by shaking and bending of hands and wrists. Pramipexole was increased to 0.375 mg, and 75 mg of pregabalin was added, but her abnormal nocturnal sensation was not improved. Overt hyperthyroidism was revealed by thyroid function test: free thyroxin 2.99 ng/dL and thyroid-stimulating hormone 0.009 µIU/mL. One month later, her symptom showed much improvement after taking methimazole 5 mg twice a day. We report a case of abnormal nocturnal sensation of hands in the patient with hyperthyroidism who responded with methimazole.

BACKGROUND: The described clinical characteristics of early-onset Alzheimer's disease (EOAD) are distinct from that of late-onset AD. We reported a patient with atypical EOAD. CASE REPORT: A 54-year-old, truck driver developed gradual visuospatial, language and calculation deficits for 3 months. The neuropsychological impairments were extensive. Brain MRI revealed asymmetric atrophy in left medial temporal lobe along with distinct widening of sylvian fissure. (18)F-florbetapir-positron emission tomography (PET) showed a high uptake in the cortex. Further, the profiles of cerebrospinal fluid (CSF) biomarker were compatible with AD. CONCLUSIONS: We diagnosed the patient as EOAD based on the result of biomarker study. Increased Abeta burden was identified through amyloid PET imaging and decreased CSF Abeta level. The high rise of CSF Tau proteins was in agreement with the patient's extensive and rapid cognitive decline. This case report demonstrates the importance of AD biomarker study in confronting early-onset dementia with atypical clinical presentation.
