1.A Case of Systemic Lupus Erythematosus with Recurrent Myelitis and Optic Neuritis.
Journal of the Korean Neurological Association 2000;18(5):657-660
Neurological manifestations of systemic lupus erythematosus (SLE) can mimic multiple sclerosis (MS) or Devic's syndrome (DS). We report a 16-year-old woman with recurrent myelitis and optic neuritis. She also had an antinuclear antibody, an anti double-stranded DNA antibody and a positive lupus erythematosus cell. Because MS is a diagnosis of exclusion, brainstem involvement is not compatible with DS. We therefore diagnosed her case as a SLE with recurrent myelitis and optic neuritis.

BACKGROUND AND PURPOSE: A carboxy-O-methyl transferase inhibitor entacapone has been introduced as an adjuvant drug for Parkinson disease (PD) patients. Although clinical trials reported beneficial role of entacapone, a long-term trial over 3 years failed to show significant effect. The goals of this study were to evaluate the clinical benefit and the efficacy of entacapone in an open clinical practice. METHODS: After the completion of a double-blind placebo-controlled entacapone study, 149 patients from 4 centers were included. Antiparkinsonian medications were optimized by the judgment of the neurologists in charge. The clinical global impression (CGI) scale was obtained at 6 months and 1 year after the initiation of entacapone treatment. RESULTS: Of the 149 patients, 117 patients chose to try entacapone in an open-label fashion. Sixty-nine (59%) patients completed the 1-year trial. Twenty-nine patients discontinued entacpaone before 6 months, and 19 between 6 months and 1 year during trial. Twelve patients out of 48 patients discontinued entacapone because of its poor efficacy. The CGI scale was 3.9 (+/-1.5) at the beginning of the trial, 4.3 (+/-1.1) at 6 month, and 3.8 (+/-1.3) at 1 year, respectively. The CGI scale of those who discontinued between 6 month and 1 year was 3.4 (+/-1.7), which was worse, but insignificantly, than that of the continuer. CONCLUSIONS: The dropout at 1 year of our study was very high at 41%. Even though entacapone is indicated for advanced PD patients with motor fluctuation, the fluctuators commonly have dyskinesia and mental symptoms, which can become more troublesome with entacapone. In the patients with advanced PD, the clinical efficacy and side effects should be carefully considered in a long-term use of entacapone.

Objectives: To survey daily doses of dopaminergic medications and to draw a posteriori equation of the
dose in relation to the various clinical variables in Korean patients with Parkinson disease. Methods:
A multi-center cross-sectional survey was conducted over a defi ned period. Information on patient
demographics and clinical features including age at Parkinson disease onset, disease duration, treatment
duration and Hoehn and Yahr stage, and daily doses of anti-parkinsonian drugs was obtained from
the patients’ medical records. Results: A total of 1,762 patients with Parkinson disease were recruited
from 6 referral centers. The mean L-dopa equivalent daily dose (LEDD) in the whole population was
608.9 mg/day, which tended to increase linearly depending on the duration of disease and Hoehn and
Yahr stage. LEDD was also signifi cantly affected by age and gender. We performed multiple linear
regression analyses and devised a posteriori equation of LEDD with clinical variables.
Conclusions: This survey provides systematic data for mean LEDD in Korean Parkinson disease
patients. In spite of profound individual variations in LEDD, our linear regression model provides an
insight about the relationship between daily doses of dopaminergic medications and various clinical
features of Parkinson disease.

BACKGROUND/AIMS: As an underprivileged population, homeless people have a higher incidence of morbidity and mortality than do non-homeless people. Diabetes mellitus is a chronic disease associated with high complication rates; its incidence is increasing rapidly and it requires prompt, adequate treatment and care. Therefore, we investigated the quality of medical care provided to homeless diabetics in a general hospital and comorbidities associated with diabetes. METHODS: Between March 25, 2011 and December 31, 2012, we retrospectively investigated the medical records of the diabetes patients at a general hospital in Seoul. We assigned the patients into two groups: homeless (n = 82) and non-homeless (n = 242) patients. We subsequently compared the clinical and laboratory findings, comorbidities, and complications between the two groups. RESULTS: The homeless diabetics received treatment less regularly than the non-homeless patients and were diagnosed with diabetes while visiting the hospital for the treatment of other diseases. The homeless patients had higher glycated hemoglobin A1c levels than the non-homeless patients. The homeless patients had a higher rate of other diseases, such as peripheral artery disease, acute infectious disease, intracranial hemorrhage, and pulmonary tuberculosis; a higher incidence of acute infectious disease (odds ratio [OR], 15.671; 95% confidence interval [CI], 5.115-48.070); and a higher prevalence of pulmonary tuberculosis (OR, 6.423; 95% CI, 1.785-23.116) than the non-homeless patients, as determined by multivariate analysis. CONCLUSIONS: Comorbid acute infectious disease and pulmonary tuberculosis were found more frequently in homeless diabetes patients presenting to the hospital than in non-homeless diabetes patients. Therefore, attention should be paid to this differentiating factor.

Saponin has been known to be a major antioxidant component in panax ginseng. Recent experimental study suggests that some antioxidant materials prevent Parkinson's disease caused by 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP) in an animal model. The present study was performed to demonstrate the effect of ginseng saponins in the Parkinson's disease model induced by MPTP. To verify the effect of ginseng saponin on dopaminergic neurons in the mice brain, the tyrosine hydroxylase-immunoreactive (TH-ir) neurons were observed by immunohistochemical stain and immunoelectron microscopy (preembedding method). Also, in order to estimate the immunoreactivity of dopaminergic neuropils, they were quantified by image analysis. The number of TH-ir neurons of substantia nigra was significantly increased in the high-dose (0.46 mg/kg) ginseng saponin group compared with the MPTP injected group. The immunoreactivity of TH-ir neuropils in striatum was significantly increased in both high and low-dose (0.1 mg/kg) ginseng saponin groups compared with the MPTP injected group. In immunoelectron microscopic observation, TH-ir neurons of the control and both ginseng saponin injected group showed normal nuclei and well preserved cytoplasmic organelles. In the MPTP injected group, dying dopaminergic neurons showed destroyed nuclei and cytoplasmic organelles. These results suggest that ginseng saponin has a protective effect on the Parkinson's disease model induced by MPTP.

PURPOSE: To report a rare case of Aspergillus endophthalmitis as a preceding symptom of central nervous system (CNS) lymphoma. CASE SUMMARY: A 66-year-old female was admitted to our clinic with mental change for 3 days. Seven months earlier, she had been diagnosed with retinal vasculitis in an ophthalmology clinic because of blurred vision in both eyes and was administered steroid therapy. Three months earlier, because of progressive symptoms, vitreous fluid culture had been performed and showed Aspergillus endophthalmitis. She was treated with intravitreous voriconazole injection and oral voriconazole. Initial brain magnetic resonance imaging (MRI) and cerebrospinal fluid study was normal. Two months later, a second MRI showed multiple enhancing lesions, which were aggravated on the third MRI at admission to our clinic. Although brain biopsy was not performed due to the poor condition of the patient, CNS lymphoma was suspected based on the neuroimaging. After steroid pulse therapy and whole brain radiation, follow-up neurologic examination showed improved mental state, and follow-up MRI showed remarkable shrinkage of multiple lesions. CONCLUSIONS: As Aspergillus endophthalmitis is an opportunistic infection in those with an immune-compromised state and the orbit is near the central nervous system, the clinician should be alert to concomitant disorders in CNS. For a prompt and accurate diagnosis of CNS disorder, early evaluation of neurologic symptoms beyond symptoms of endophthalmitis and neuroimaging is essential.

PURPOSE: The purpose of this study was to analyze the CT findings of hepatoblastoma before and afterchemotherapy, and to compare them with surgical and pathologic features. MATERIALS AND METHODS: Twelvehepatoblastoma patients underwent chemotherapy prior to surgery; in all cases, CT scanning was performed beforeand after chemotherapy. We reviewed the findings with special attention to changes in tumor volume, the extent andpattern of contrast enhancement, the extent of low-attenuation area in the tumor, the presence of a septum, andcalcification or ossification within the mass before and after chemotherapy. Post-chemotherapy CT findings werecompared with operative and pathologic findings. RESULTS: After chemotherapy, the volume of the tumor massdecreased in all patients, and the extent of involved segments decreased in nine(75%), the non-enhancing areawithin the mass, on the other hand, increased in nine (75%). On pre-chemotherapy CT, calcifications were detectedin seven patients(58%), and on post-chemotherapy CT, in nine (75%); the extent of calcification increased in sevenpatients. On the basis of CT findings, viable tumor and necrosis areas could not be distinguished. Massivecalcification or an osteoid mixed with loose connective tissue was noted in the mesenchymal component of thetumor; the whirling pattern of enhancement within the area of low density asen on CT scanning corresponded toosteoid mixed with loose connective tissue, which contained rich blood vessels. CONCLUSION: We describe the CTfindings of hepatoblastoma both before and after chemotherapy, highlighting the changes which occurred. Anunderstanding of these changes is helpful for the proper management of this condition.

A 59-year old man was admitted for drowsiness and stiff neck. CSF examination showed lymphocytic pleocytosis and PCR for herpes simplex virus (HSV)-1 was positive in CSF. Brain MRI revealed enhanced lesions in left temporal lobe. His symptom improved with acyclovir. Follow-up studies showed red blood cells in CSF and a hematoma in the left temporal lobe. There was no additional symptom related to the hematoma. He was discharged after conservative care. Although rare, hematoma can develop in HSV-1 meningoencephalitis.

General anesthesia for the removal of a large mediastinal mass has been associated with life-threatening airway obstruction. We present a case of general anesthesia for a patient with superior posterior mediastinal mass and critical airway compression who was allowed to maintain spontaneous ventilation throughout general anesthesia for a thoracotomy. The patient was a 5-year-old boy complaining of productive cough and intermittent fever for 3 weeks. His chest radiograph and magnetic resonance imaging(MRI) film demonstrated a critically narrowed and deviated trachea at the level of the thoracic inlet to the proximal portion of the right bronchus. We can secure the airway by spontaneous ventilation without muscle relaxation and allowing the patient to breathe spontaneously and insertion of endotracheal tube distal to the narrowed portion of trachea.
