Aconitine is a main component of Aconitum carmichaeli, a Chinese herb known to be effective for
arthritis and neuralgia. Many senior citizens consume the herb as a folk remedy. Aconitine-associated
cardiogenic toxicity has been observed but aconitine-induced cerebrovascular event has not been
reported so far. We report two elderly patients who became unconscious and showed neurological
dysfunction soon after ingesting aconitine for pain control. We speculate that the aconitine induced
cardiac arrhythmia. This resulted in cardiogenic emboli formation with subsequent large territory
cerebral infarction.

Objective: Peripheral arterial disease (PAD) reduces functional activity and increases the rate of
cardiovascular death in the elderly. Our study aimed to determine whether the presence of PAD in
stroke patients affected the progression of disability or death one year after discharge. Methods: From
April 2012 to March 2013, consecutive first stroke patients above 50 years of age without known PAD
were enrolled. PAD was defined as a low ankle-brachial index (less than 0.9) measured by an automatic
device. Clinical data associated with the stroke were collected from medical records. Disability in stroke
patients was evaluated with the modified Rankin scale (mRS) on discharge day and one year after the
index stroke. Progression of disability was defined as an increase in mRS more than one level at one
year. Results: Among the 526 patients, 238 had ischemic strokes and underwent ankle-brachial index
(ABI) measurement. Of them, 192 patients were included. In univariate analysis, age, dyslipidemia,
discharge mRS, low-density lipoprotein cholesterol, D-dimer, homocysteine, internal carotid artery
stenosis, posterior cerebral artery stenosis, and PAD were factors associated with worsening mRS.
After adjustment for these factors in the logistic regression analysis, PAD was an independent factor
associated with worsening mRS. In the analysis of one-year mortality, patients with PAD had a higher
death rate, but PAD was not an independent factor after adjusting for other variables.
Conclusions: The presence of PAD in stroke patients suggests a chance of disability progression, but
may not be a predictor of death after one year.

Neurology Asia 2016;21(4):317-324
Background & Objective: The number of ischemic stroke is increasing steadily. The recent stroke
prevention strategies have targeted risk factors for preventing ischemic stroke. Community-based data
that quantify the prevalence of these risk factors are needed to develop effective stroke prevention
strategies. This study was performed aiming to establish customized prevention strategies by investigating
vascular risk factors of ischemic stroke among the healthy adults in an urban population in Korea.
Methods: The Prevention of Stroke and Dementia (PRESENT) survey collected data associated with
stroke risk factors between 2007 and 2009 in Ansan city, Korea. Of 46,537 people, 2,843 were selected
by random sampling, and final population included 358 men and 422 women over 50 years old. We
checked modifiable risk factors, such as hypertension, diabetes mellitus, smoking, hyperlipidemia,
atrial fibrillation, cardiovascular disease, obesity, and physical inactivity. Results: The mean age of
study subjects was 60.1±8.2 years; 55.5% had hypertension, 18.6% had diabetes mellitus, 17.7% were
current smoker, 44.9% had hyperlipidemia, 1.7% had atrial fibrillation, and 4.5% had cardiovascular
disease. Men had more risk factors for stroke, and higher rates of diabetes mellitus and current
smoking. However, women had higher cholesterol and obesity rates and lower physical activity. The
proportion of individuals with >1 risk factor for stroke increased with age. Hypertension, diabetes
mellitus, and cardiovascular diseases also increased with age, but low-density lipoprotein levels and
current smoking decreased.
Conclusions: This study provides valuable information to develop customized strategic policies for
primary and secondary stroke prevention.

Reversible splenial lesion syndrome can be caused by viral infection. Rubella generally occurs in
childhood, and it is rarely accompanied by neurological complications in adulthood. A 35-year-old man
visited our hospital due to conjunctival injection, mild fever, and headache 3 days after experiencing
skin rash. Brain magnetic resonance imaging (MRI) revealed distinct lesions involving white matter in
the splenium of the corpus callosum approximately 3 days following the onset of symptoms. Enzyme
immunoassay performed on serum and CSF samples was positive for rubella virus IgM. A follow-up
brain MRI was performed 24 days after the onset of symptoms, and reduced lesion size with decreased
signals were observed on diffusion weighted image. This case showed that rubella infection can result
in reversible splenial lesion accompanied by only mild neurological symptoms.

The most frequently reported neurological complication of a wasp sting is ischemic stroke. We
treated a patient with wasp sting with unusual complications. A 52-year-old man was hospitalized
for anaphylactic shock after multiple wasp stings. Although the patient recovered consciousness
after 2 days, he had global aphasia and right hemiparesis. Brain magnetic resonance imaging and
angiography revealed high-intensity signals in the left basal ganglia and cerebral cortex and stenosis
of the left middle cerebral artery. After 2 days, the middle cerebral artery stenosis improved. After 5
days, diffusion-weighted imaging showed an enlarged lesion in the left frontal cortex. The infarct in
this case was due to a predominantly unilateral vasoconstrictive hypoxic brain injury from wasp stings.

Journal of the Korean Neurological Association 2019;37(2):150-155
BACKGROUND: Selecting the appropriate patients and reducing stroke onset to endovascular recanalization therapy (ERT) time are essential elements of a successful ERT. Since ERT is available only in large hospitals, proper patients transfer is important. The purpose of study is to examine the suitability of the transfer of acute stroke patients. METHODS: We retrospectively reviewed the medical records of patients who diagnosed as acute ischemic stroke from January to December in 2017. Patients were divided into two groups based on transfer (direct visit vs. transfer) and Alberta Stroke Program Early computed tomography (ASPECT) score (≥8 vs. <8) respectively. Each group was assessed by demographics, type and rate of reperfusion therapy, onset to reperfusion therapy time, stroke risk factors and neurological deficit severity. Interhospital distance and transfer time was calculated in transferred patients. RESULTS: Among the 455 patients, the 228 (50.2%) patients underwent interhospital transfer. The ratio of reperfusion therapy was not significant different between direct visit and transferred group (34.8% vs. 37.3%, p=0.397). The transferred patients tended to be older (p=0.003), female (p=0.001), more hypertension (p=0.019), less transient ischemic attack (p=0.001), longer onset to ERT time (178.55±85.92 vs. 131.48±82.89; p=0.001) lower ASPECT score (6.72±2.04 vs. 8.01±1.65; p<0.001) and higher National Institute of Health Stroke Scale (NIHSS) (p<0.001) and modified Rankin Scale (mRS) (p<0.001). High ASPECT score (≥8) patients were more direct visited (63.9%), shorter onset to ERT time (p=0.047), lower initial NIHSS and mRS (p<0.001), and greater in differences between mRS at admission and 3 months later (p=0.016). CONCLUSIONS: This study suggests emergency and interhospital transfer of acute stroke patients is inefficient, and systematization of transfer is necessary.

This dealt with the 23 cases of giant cell tumor of femur and tibia who were treated with curettage and cementation of the lesion, over 14 year period. Cement by virtue of it's heat of polymerization may “sterilize” the wall upto 3-5mm in depth. Authors adoped cement treatment as an effective adjuvant after intra-lesional surgery(curettage). Curettage was indicated in all stage I lesions; most stage 2 and some stage 3 lesions, provided the residual bone stock were sufficient to make it oncologically and mechanically effective. The follow-up period ranged from 3 to 14 years(oaverage 8 years and 6 months). The sites of the lesions were proximal tibia in 8, dital femur in 13, proximal femur in one, and distal tibia in one. Among these cases, 3(13.0%) cases(two grade 1 and one grade 2) of stage II(To: active), and 2(8.7%) of stage III(grade 2) (Tl or T2: aggressive). Utmost attention was paid to nulify or to reduce the local seeding of the tumor cell during aggressive curettage, which was followed by electrical cautery of the cavitey wall, and lastly by the cavity obliteration with bone cement. None of the cases had lung metastasis. Only in a stage III GCT case(4.3%) of local recurrence after curettage and bone and artificial bone graft, recurettage and cementation brought the successful outcome. Through this study, it was reconfirmed that with correct indications the use of cement as a local adjuvant in conjuction with curettage was effective method in treating GCT without any side effects.
