Dizziness can be classified mainly into 4 types: vertigo, disequilibrium, presyncope, and lightheadedness. Among these types, vertigo is a sensation of movement or motion due to various causes. The main causes of peripheral vertigo are benign paroxysmal positional vertigo (BPPV), acute vestibular neuritis (AVN), and Meniere's disease. BPPV is one of the most common causes of peripheral vertigo. It is characterized by brief episodes of mild to intense vertigo, which are triggered by specific changes in the position of the head. BPPV is diagnosed from the characteristic symptoms and by observing the nystagmus such as in the Dix-Hallpike test. BPPV is treated with several canalith repositioning procedures. AVN is the second most common cause of peripheral vertigo. Its key symptom is the acute onset of sustained rotatory vertigo without hearing loss. It is treated with symptomatic therapy with antihistamines, anticholinergic agents, anti-dopaminergic agents, and gamma-aminobutyric acid-enhancing agents that are used for symptoms of acute vertigo. Meniere's disease is characterized by episodic vertigo, fluctuating hearing loss, and tinnitus. It is traditionally relieved with life-style modification, a low-salt diet, and prescription of diuretics. However, diagnosis and treatment of the peripheral vertigo can be difficult without knowledge of BPPV, AVN, and Meniere's disease. This article provides information on the differential diagnosis of peripheral vertigo in BPPV, AVN, and Meniere's disease.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children. The global prevalence of pediatric NAFLD from general populations is 7.6%. In obese children, the prevalence is higher in Asia. NAFLD has a strong heritable component based on ethnic difference in the prevalence and clustering within families. Genetic polymorphisms of patatin-like phospholipase domain-containing protein 3 (PNPLA3), transmembrane 6 superfamily member 2, and glucokinase regulatory protein (GCKR) are associated with the risk of NAFLD in children. Variants of PNPLA3 and GCKR are more common in Asians. Alterations of the gut microbiome might contribute to the pathogenesis of NAFLD. High fructose intake increases the risk of NAFLD. Liver fibrosis is a poor prognostic factor for disease progression to cirrhosis. Magnetic resonance spectroscopy and magnetic resonance proton density fat fraction are more accurate for steatosis quantification than ultrasound. Noninvasive imaging methods to assess liver fibrosis, such as transient elastography, shear-wave elastography, and magnetic resonance elastography are useful in predicting advanced fibrosis, but they need further validation. Longitudinal follow-up studies into adulthood are needed to better understand the natural history of pediatric NAFLD.

Purpose: This study was conducted to investigate the frequency and clinical characteristics of anaphylaxis patients who are registered inaccurately with other disease codes. Methods: Study subjects presenting at the emergency department (ED) were retrospectively collected using disease codes to search for anaphylaxis patients in a previous studies. The study group was divided into an accurate and inaccurate group according to whether disease codes were accurately registered as anaphylaxis codes. Results: Among 266 anaphylaxis patients, 144 patients (54%) received inaccurate codes. Cancer was the most common comorbidity, and the radio-contrast media was the most common cause of anaphylaxis in the accurate group. Cutaneous and respiratory symptoms manifested more frequently in the inaccurate group, while cardiovascular and neurological symptoms were more frequent in the accurate group. Blood pressure was lower, and shock and non-alert consciousness were more common in the accurate group. Administration of intravenous fluid and epinephrine use were more frequent in the accurate group. Anaphylaxis patients with a history of cancer, shock, and epinephrine use were more likely to be registered as anaphylaxis codes accurately, but patients with respiratory symptoms were more likely to be registered with other disease codes. Conclusion: In cases of anaphylaxis, the frequency of inaccurately registered disease codes was higher than that of accurately registered codes. Anaphylaxis patients who were not treated with epinephrine at the ED who did not have a history of cancer, but had respiratory symptoms were at increased risk of being registered with disease codes other than anaphylaxis codes.

Cervical cancer is the second most common cause of cancer-related death among women worldwide, with over 500,000 new cases diagnosed annually and 50% mortality rate in Asia. In the United States, approximately 10,370 new cases of cervical cancer are diagnosed annually, and estimated 3,710 deaths occur from the disease, making it the sixth most common cause of malignancy among American women. This study aims to provide awareness about cervical cancer as well as an updated knowledge about the prevalence and incidence of cervical cancer in Asia.

The most common cause of isolated oculomotor nerve palsy is ischemia of the peripheral nerve caused by a disease, such as diabetes mellitus. Another common cause of isolated oculomotor nerve palsy is compression by an intracranial aneurysm, usually an posterior communicating artery aneurysm. However, it is extremely rare in the pituitary tumor. We report an unusual case of pituitary adenoma presenting with isolated oculomotor nerve palsy in the setting of pituitary apoplexy. We suggest that pituitary apoplexy should be included in the differential diagnosis of a patient with isolated oculomotor nerve palsy and early surgery should be considered for preservation of oculomotor nerve function.

1. Objectives Hoarseness is most common symptoms of URI. Acute laryngitis, chronic laryngitis, vocal nodules, laryngeal cancer can be the cause of hoarseness, but laryngitis is most common cause. this hoarseness is called as 'Um-a' in Korean medicine and other disease, 'Um-a' can be treated by Sasang constitutional medical diagnosis and treatment. 2. Methods There is two case-reports of the patients who were hoarse and they were treated with Sasang constitutional medicine, Samgyepalmul-tang. 3. Results The patients had shown remarkable clinical effects, when Sasang constitutional medical treatment was practiced. 4. Conclusions Thus we report the healing process and result of this two hoarse patients.

Escherichia coli is recovered from a wide variety of infections in many animals species. It may be a primary or secondary agent. Nursing and young animals are particularly susceptible, and urinary tract infections are frequent. The various serotypes of E coli are intestinal inhabitants of animals including humans and probably infect most mammals and birds : therefore, they have a cosmopolitan distribution. Colibacillosis refers to any totalized or systemic infection caused entirely or partly by E coli. Collibacillosis in mammals is most often a primary enteric disease, whereas collibacillosis in poultry is typically a secondary located or systemic disease occurring when host defenses have been impaired or overwhelmed. Other opportunistic bacteria, which can be identified by culture, may play a similar role to that of I coli in secondary infections. Collectively, infections caused by E coli are responsible for significant economic losses to the animal performance. From the standpoint of pathogenic mechanisms and diseases, four major categories of E coli are recognized : enterotoxigenic(ETEC), enteropathogenic (EPEC), enteroinvasive(EIEC), and enterohemorrhagic(EHEC). In addition, two less-well-defined E coli categories are recognized in animals and humans : enteroaggregative and cytotoxin necrotizing factor-positive. The aforementioned categories are represented by different serotypes. Certain serotypes show a host preference and are encountered more frequently in some disease syndromes. Of the four major categories, ETEC is the most common cause of diarrhea in calves, lambs, and pigs. Strains in the other categories cause the less-common diarrhea and other disease syndromes. Enterotoxins and pilus antigens are the two most prominent virulence factors thus far identified for ETEC. Two enterotoxins, one heat-stable(ST) and one heat-labile(LT), are produced by enterotoxigenic strains of E coli : not all culture produce both of these plasmid-based enterotoxins.

Acute event in cerebrovascular disease is the second most common cause of death in Korea following cancer, and it can also cause serious neurologic deficits. Understanding of perfusion status is important for clinical applications in management of patients with cerebrovascular diseases, and then the attacks of ischemic neurologic symptoms and the risk of acute events can be reduced. Therefore, the normal vascular anatomy of brain, various clinical applications of acetazolamide-enhanced brain perfusion SPECT, including meaning and role of assessment of vascular reserve in carotid stenosis before procedure, in pediatric Moyamoya disease before and after operation, in prediction of development of hyperperfusion syndrome before procedure, and in prediction of vasospasm and of prognosis in subarachnoid hemorrahge were reviewed in this paper.

Lesions occurring simultaneously in the somatosensory or motor cortex of the brain and the cervical spine are rare. Brain tumors can cause similar symptoms to cervical lesions which can lead to confusion in treatment priorities. Moreover, if cervical disease is noticeably observed in radiologic findings of a patient complaining of cervical radiculopathy with non-specific electromyography results, it is common to no longer perform further evaluation. Here we introduce two cases where the cause of cervical radiculopathy was first considered to be the result of a degenerative cervical disease but was later discovered to be a result of a brain tumor.

It is well known that unilateral vocal cord paralysis is a sign of a disease and not a disease entity. In an attempt to evalute incidence of unilateral vocal cord paralysis related to varoius causes and to analyze our treatment results, the records of 210 patients seen at the Department of Otorhinolaryngology, Yongdong Severance Hospital during the 10-year period from March 1985 to March 1995 were reviewed. Fifty-three patients(25.2%) of the 210 patients with unilateral vocal cord paralysis had surgery-related causes, and intubations including tracheostomy was the most common etilogy among them. One hundred and fifty seven cases(74.8%) was not related to surgery and, among these most common cause was idiopathic. Spontaneous recovery took place in 17(8%) patients. Phonosurgery including type Ⅰ thyroplasty(n=16) and arytenoid adduction(n=10) and combination of them(n=3) yielded good results except intrafold teflon injection(n=4). These results of our series were compared to other series reported over the past decades.
