The purpose of this clinical practice guideline (CPG) is to provide current and comprehensive recommendations for the medical and surgical management of primary intracerebral hemorrhage (ICH). Since the release of the first Korean CPGs for stroke, evidence has been accumulated in the management of ICH, such as intracranial pressure control and minimally invasive surgery, and it needs to be reflected in the updated version. The Quality Control Committee at the Korean Society of cerebrovascular Surgeons and the Writing Group at the Clinical Research Center for Stroke (CRCS) systematically reviewed relevant literature and major published guidelines between June 2007 and June 2013. Based on the published evidence, recommendations were synthesized, and the level of evidence and the grade of the recommendation were determined using the methods adapted from CRCS. A draft guideline was scrutinized by expert peer reviewers and also discussed at an expert consensus meeting until final agreement was achieved. CPGs based on scientific evidence are presented for the medical and surgical management of patients presenting with primary ICH. This CPG describes the current pertinent recommendations and suggests Korean recommendations for the medical and surgical management of a patient with primary ICH.

Background: Moyamoya disease is characterized by a progressive stenosis or occlusion of the intracranial internal carotid artery and/or the proximal portion of the anterior cerebral artery and middle cerebral artery. Whether the onset time was childhood or adulthood, the bony carotid canal diameter might be different, but reflects the size of internal carotid artery passing through the bony carotid canal. In this study, we aimed to identify the relationship between bony carotid canal diameter and clinical manifestation. Methods: 146 consecutive patients diagnosed with moyamoya disease by brain imaging studies were included. We measured the diameter of a transverse portion of bony carotid canal on bone window of a brain computed tomography(CT) image. Patients were divided into two groups, ischemic or hemorrhagic stroke according to clinical manifestation. As a result, 115 patients were included. The Suzuki stage was used as criteria for disease progression. Results: Bony carotid canal diameter was $3.6{\pm}0.5$ (right) and $3.6{\pm}0.4$ (left) in the hemorrhagic stroke group, and $3.7{\pm}0.4$ (right) and $3.6{\pm}0.4$ (left) in the ischemic stroke group. The bony carotid canal diameter of the moyamoya vessels (3.6 mm) was smaller than the diameter of non-moyamoya vessels (3.8 mm), significantly (p = 0.042). However, there was no difference in the collateral patterns and clinical manifestation in a comparison of both groups. Conclusions: In our study, there was no significant difference of clinical manifestations and collateral patterns depend on the bony carotid canal diameter in patients with moyamoya disease. These findings suggest that the clinical presentations of moyamoya disease are not related to the onset time of the disease.

Transcranial magnetic stimulation (TMS) is a safe and noninvasive tool for investigating the cortical excitability of the human brain and the neurophysiological functions of GABAergic, glutamatergic, and cholinergic neural circuits. Neurophysiological biomarkers based on TMS parameters can provide information on the pathophysiology of dementia, and be used to diagnose Alzheimer's disease and differentiate different types of dementia. This review introduces the basic principles of TMS, TMS devices and stimulating paradigms, several neurophysiological measurements, and the clinical implications of TMS for Alzheimer's disease.

Acute pulmonary embolism (PE) is a life-threatening disease that manifests with cardiorespiratory symptoms. Syncope can be a rare, but warning sign of PE. We report a case of a 49-year-old male diagnosed with PE who presented with recurrent syncope prior to typical cardiorespiratory symptoms. His computed tomography pulmonary angiogram revealed bilateral PE. Syncope can be a rare clinical symptom of PE, but considering lethality of the disease, a differential diagnosis of PE should be considered in patients with recurrent syncope.

Thyrotoxic periodic paralysis (PP) is the most common acquired form of PP in Asian populations, and its cardinal and biochemical abnormality is hypokalemia. We describe a 39-year-old man who had acute bilateral limb motor weakness and paresthesia, and showed normokalemia during attack. Thyroid studies showed subclinical thyrotoxic Goiter. Control of the hyperthyroidism nearly eliminated his PP. Regardless of normokalemia, our patient might be a case of hypokalemic PP because of improvement from anti-thyroid medication.

Colchicine is a drug used for the treatment of acute gouty arthritis or various autoimmune diseases. Gastrointestinal adverse effects such as abdominal pain and vomiting are the common side effects of the drug, but rarely myopathy has been reported to occur particularly in renal recipients who were treated concomitantly with immunosuppressants. Herein, we report a case who presented with acute myopathy after treated with colchicine for acute gouty arthritis.

Myotonic dystrophy type 1 (DM1) is an autosomal dominant multisystem disorder caused by the expansion of cytosine-thymine-guanine (CTG) repeats in the myotonic dystrophy protein kinase (DMPK) gene. Some literatures indicated that DM1 had incidental CNS lesions such as white matter lesions and diffuse gray matter atrophy. We report a patient with DM1 whose brain magnetic resonance image (MRI) showed multifocal hyperintense lesions and cystic lesion on both frontotemporoparietal lobes.

The Guillain-Barre Sydrome (GBS) is post-infectious autoimmune disease and it could be caused by auto-antibodies produced after infections. Mycoplasma pneumoniae is one of rare cause of GBS and known to be associated with antibody to galactocerebroside (GalC) which is a major neutral glycolipid constituent of myelin. We report a case of GBS with immunoglobulin M GalC antibody after M. pneumoniae infection.

Postural orthostatic tachycardia syndrome (POTS) is characterized by increased heart rate with preserved blood pressure on orthostatic stress. Many patients with postural orthostatic tachycardia syndrome can be misdiagnosed as neurosis, chronic fatigue or anxiety disorder. We report a patient with POTS who presented chronic dizziness and fatigue. In approaching to a patient with orthostatic or nonspecific chronic dizziness, the postural heart rate as well as blood pressure should be checked not to miss the diagnosis.

Nephrogenic systemic fibrosis (NSF) is a systemic disease that affects the skin and other tissues in patients with renal insufficiency and exposure to gadolinium-containing contrast. A 55-year-old woman with end-stage renal disease on hemodialysis was consulted for progressive general weakness. After she had undergone multiple MRIs with gadolinium-containing contrast media, muscle weakness and skin lesions were developed. Her skin and muscle biopsy specimens showed CD34+ fibroblast entrapping collagen bundles. There are few reports of NSF with myopathy.
