A Case of Unusual Pituitary Apoplexy Presented as Aseptic Meningitis.
Korean Journal of Clinical Neurophysiology.2013;15(1):24-26. doi:10.14253/kjcn.2013.15.1.24
We encountered a case of pituitary apoplexy who presented with isolated headache and vomiting without visual disturbance or ophthalmoplegia. The cerebrospinal fluid examination was compatible with aseptic meningitis. A computed tomography revealed slightly high density in the pituitary fossa and suprasella area, but the signal change was very faint. Our case suggests that clinicians should take into account the possibility of pituitary apoplexy without visual disturbance or ophthalmoplegia, when aseptic meningitis is suspected.

Leprous Neuropathy Associated with Predominant Proprioceptive Sensory Loss.
Korean Journal of Clinical Neurophysiology.2013;15(1):19-23. doi:10.14253/kjcn.2013.15.1.19
Some patients with leprosy may present with atypical features, such as isolated peripheral neuropathy without skin lesions, or marked proprioceptive dysfunction. We report a 56-year-old female who presented with predominant proprioceptive loss without skin lesion, but was finally confirmed as leprous neuropathy by sural nerve biopsy. It is postulated that large myelinated fibers were affected by chronic immunological reactions triggered by inactive bacterial particles, producing a peripheral neuropathy presenting as predominant proprioceptive sensory loss without typical skin lesions.

Subacute Inflammatory Demyelinating Polyneuropathy Combined with Optic Neuritis.
Korean Journal of Clinical Neurophysiology.2013;15(1):13-18. doi:10.14253/kjcn.2013.15.1.13
It was sometimes difficult to differentiate between acute-onset chronic inflammatory demyelinating polyneuropathy (A-CIDP) and subacute inflammatory demyelinating polyneuropathy (SIDP). The CNS involvement of these polyneuropathies has rarely reported in the literature. We present the case of a 42-year-old man who developed rapidly developing inflammatory demyelinating polyneuropathy followed by right optic neuritis. This case showed progressive motor weakness and sensory dysfunction with time to nadir at 8 weeks, demyelination in nerve conduction study, no other etiology of neuropathy, no relapse during follow-up of 18 months, good response to steroid and complete recovery which favor SIDP more than A-CIDP. We experienced the case of SIDP associated with optic neuritis.

BACKGROUND: Local steroid injection is used to treat carpal tunnel syndrome (CTS). The aim of this study was to evaluate the clinical and electrophysiological effects of local steroid injection in patients with CTS over a 3-months period. METHODS: Twenty-one patients (35 hands) with clinical and electrophysiological evidence of CTS were treated by injection of triamcinolone 40 mg to the carpal tunnel. Visual analog scale (VAS), Boston Carpal Tunnel Questionnaire (BCTQ), rates of paresthesia, night awakening, and electrophysiological studies were used as outcomes. Clinical and electrophysiological assessments were performed before, 1 and 3 months after treatment. RESULTS: Prior to treatment, 86% of patients complained of night awakening. At 1 and 3 months after injection, only 17% and 29% of the patients, respectively, had night awakening (p<0.001). All patients complained of paresthesia before the treatment. This symptom disappeared in 60% and 31% of the patients after 1 and 3 months, respectively (p<0.001). Compared to baseline, both BCTQ and VAS show significant improvement during the 3 months of the study (p<0.005). Although significant improvements in clinical parameters were shown, electrophysiological parameters were not significantly improved at 1 and 3 months. CONCLUSIONS: Local corticosteroid injection for the treatment of CTS provides significant improvement in symptoms for 3 months. On the other hand, no significant improvement was observed in electrophysiological parameters.

Clinical Analysis of Recurrent Bell's Palsy in One University Hospital.
Korean Journal of Clinical Neurophysiology.2013;15(1):1-6. doi:10.14253/kjcn.2013.15.1.1
BACKGROUND: Bell's palsy (BP) is the most common cause of unilateral lower motor facial palsy. Recurrent paralysis of the facial nerve is unusual and reported in only 7-8%. METHODS: A total of 394 consecutive patients with acute BP patients were enrolled at Daegu Catholic University Hospital from July 2005 to September 2012. We classified the patients into two groups-single BP and recurrent BP-and compared them by patient characteristics, clinical features, MRI findings, electrophysiologic findings and prognosis. The degree of BP was graded according to the House and Brackmann facial nerve grading system. RESULTS: Recurrent BP was observed in 31 (7.9%) patients. The number of recurrence was varied from 2 to 5. The recurrent BP (9.7%) had more incidence of family history and MRI enhancement than those of single BP (2.2%, p=0.047). The single BP (63.4%) had better recovery than recurrent BP (45.2%, p=0.045). CONCLUSIONS: The recurrent BP had more incidence of family history, MRI enhancement and poor prognosis than the single BP.

BACKGROUND: The effects of omega-3 polyunsaturated fatty acids (PUFAs) on cerebral vessels have not been clarified until now. Thus we investigated the efficacy of omega-3 PUFAs supplementation on cerebral blood flow velocity and vascular resistance via transcranial doppler (TCD). METHODS: Consecutive twenty patients (13 male and 7 female) with at least 1 cerebrovascular risk factor or a known cerebrovascular disease were enrolled. Patients were treated with omega-3 PUFAs (1 g, two times per day) for 12 weeks. Cerebral blood flow velocity, resistance index, and pulsatile index were checked before and after 12 weeks of treatment using TCD. RESULTS: The change of resistance index in right MCA (from 0.58 +/- 0.07 to 0.55 +/- 0.07, p = 0.042) and left PCA (from 0.56 +/- 0.07 to 0.53 +/- 0.06, p = 0.037) showed significant improvement after 12 weeks of omega-3 PUFAs treatment. The changes in other vessels, however, failed to show any significant changes compared to the baseline. CONCLUSIONS: Omega-3 PUFAs treatment showed feasible efficacies for cerebral vascular resistances in this open label trial. To confirm these results, larger samples of patients and longer period of follow-up is warranted.

Has Snoring Significance for Predicting Obstructive Sleep Apnea Severity?.
Korean Journal of Clinical Neurophysiology.2015;17(2):61-67. doi:10.14253/kjcn.2015.17.2.61
BACKGROUND: The aim of this study was to investigate the predictive value of snoring frequency in the diagnosis and severity of obstructive sleep apnea. METHODS: Patients who underwent polysomnography with one or more of the following characteristics were included: 1) sleepiness, non-restorative sleep, fatigue, or insomnia symptoms; 2) arousal due to cessation of breathing or the occurrence of gasping or choking when waking up; and 3) habitual snoring, breathing interruptions, or both, noted by a bed partner or other observer. We analyzed the differences in clinical and polysomnographic variables between patients with and without obstructive sleep apnea and investigated the associations of those variables with obstructive sleep apnea severity. RESULTS: One hundred ninety-three patients met the inclusion criteria, and 145 of the 193 patients were diagnosed with obstructive sleep apnea. Multiple logistic regression analysis showed that large neck circumference (p = 0.0054) and high snoring index (p = 0.0119) were independent predictors for obstructive sleep apnea. Moreover, between the obstructive sleep apnea severity groups, there was a strong tendency of difference in body mass index (p = 0.0441) and neck circumference (p = 0.0846). However, there was no significant difference in snoring frequency according to obstructive sleep apnea severity (p = 0.4914). CONCLUSIONS: We confirmed that snoring frequency is a predictor of obstructive sleep apnea. In addition, we showed for the first time that snoring frequency is not associated with obstructive sleep apnea severity, thus it is not a valuable marker for predicting obstructive sleep apnea severity.
