Some herbal medications induce acute kidney injury. The acute kidney injuries caused by herbal medications are mild and commonly treated by palliative care. A 51-years-old man who drank the juice squeezed from the raw tubers of Dioscorea quinqueloba (D. quinqueloba) was admitted with nausea, vomiting and chilling. He developed a seizure with decreased level of consciousness. He was diagnosed with acute kidney injury, which was cured by continuous venovenous hemodialfiltration. Non-detoxified D. quinqueloba can cause severe acute kidney injury with toxic encephalopathy. It is critical to inform possible adverse effects of the medicinal herbs and to implement more strict regulation of these products.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel SFTS bunyavirus (SFTSV), a member of the genus Phlebovirus in the family Bunyaviridae. SFTSV is believed to be transmitted by Haemaphysalis longicornis. Common symptoms of SFTS include high fever, vomiting, diarrhea, thrombocytopenia, leukocytopenia, and multi-organ failure with an average case-fatality rate of 12~30%. In 2009, SFTS was firstly reported in China. In 2013, 27 cases of SFTS were documented in Korea, and 6 cases were confirmed on Jeju Island. Although the pathogenesis and transmission mode of SFTS remain unclear, SFTS is now considered endemic in East Asia. Accordingly, SFTS needs to be differentiated from scrub typhus, leptospirosis, and hemorrhagic fever with renal syndrome. We here report 4 cases of SFTS preceded by a tick bite, which were in need of a differential diagnosis of scrub typhus.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne infectious disease that is caused by the genus phlebovirus in the family Bunyaviridae. The syndrome is characterized by fever, gastrointestinal symptoms, neutropenia, and thrombocytopenia. The number of reported cases and deaths in endemic areas, such as China and Japan, has increased each year. Since the first SFTS patient was identified in 2013, the number of cases have also been increasing every year in South Korea and the disease is posing a great public health concern. The number of patients is increasing and there is a high mortality rate, but there is no established treatment that has proven to be effective. The purpose of this review was to elucidate the various treatment modalities, such as plasma exchange, antiviral agents, e.g. ribavirin, high-dose steroids, and interferon.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease in South Korea with clinical features similar to those of scrub typhus. Infected patients with these two diseases usually visited the emergency department (ED) complaining of fever that was not responsive to treatment in a local clinic. Aggressive management of SFTS is required in order to prevent rapid progression and human-to-human transmission, thus rapid and accurate differential diagnosis of the two diseases in the ED is important. We reported three laboratory confirmed cases of SFTS during 2013-2014 in a single center, with fever, skin lesions, and history of outdoor activities in order to help in differential diagnosis between SFTS and scrub typhus in the ED.

BACKGROUND: North Korea's economic and public health problems began in the early 1990s as a result of the gradual loss of economic support from its communist allies, combined with an inordinate number of natural disasters. The decline in public health has increased the incidence of tuberculosis in North Koreans and refugees. This study investigated tuberculosis situation in North Korean refugees in order to prepare for the future impact of tuberculosis control in Korea. MATERIAL AND METHODS: From 2001 to 2005, tuberculosis patients among North Korean refugees who were diagnosed before or after arriving in South Korea, based on the official records of OO hospital, were enrolled in this study. The demographic and clinical data of the cases were evaluated retrospectively. RESULTS: A total of 42 TB cases were reviewed during the study period. Of these, 37 (88.1%) cases were pulmonary TB. based on the cases identified among the number of North Korean refugees' arriving each year, the annual incidence of pulmonary TB were 900 per 100,000 in 2004, 700 in 2003, The number of smear-positive patients was 20 (47.6%) and the number of culture-positive patients was 18 (42.9%). Of the M. tuberculosis isolates, 2 cases were found to be susceptible to all anti-TB drugs available, 4 were resistant to isoniazid, and 3 were multi-drug resistant. CONCLUSION: The prevalence of pulmonary TB in North Korean Refugees is high. In addition, North Korean refugees suffer from more severe tuberculosis in bacteriological and radiological aspects.

Kikuchi disease, also called histiocytic necrotizing lymphadenitis, is an uncommon, idiopathic and generally self-limited disease, characterized by cervical lymphadenopathy. It can present systemic symptoms and signs, but ocular involvement is unusual. We report a 35-year-old woman who presented sudden decreased visual acuity and a swollen lymph node on the left side of her neck. On laboratory findings, there were no evidences of infection, autoimmune disease and systemic vasculitis. She was diagnosed with Kikuchi disease and bilateral retinal vasculitis by histologic analysis of lymph node, fundoscopy and fluorescein angiography.

Severe Fever with Thrombocytopenia Syndrome (SFTS) and Crimean-Congo Haemorrhagic Fever (CCHF) are tick-borne diseases belonging to the family Bunyaviridae. Since SFTS was first reported in China in 2009, the virus was isolated and confirmed in 2011, with additional reports of SFTSV expanding its geographic range from China to South Korea and Japan. CCHFV has the widest geographic distribution of any tick-borne virus, encompassing around 30 countries from eastern China through Asia, the Middle East, and southeastern Europe to Africa. During the past decade, CCHFV has emerged in new areas of Europe, Africa, the Middle East, and Asia and has increased in endemic areas. Migratory birds are considered to play a role in dispersing CCHFV vectors, and the virus. This review summarises SFTSV and CCHFV, highlighting the role of migratory birds in the transmission of tick-borne disease.

There has been a controversy over data of thrombolytic and endovascular surgical treatment about cerebral infarction secondary to infective endocarditis. We report a woman who received early mechanical embolectomy as a treatment of acute stroke with infective endocarditis. A 35-yr-old woman was hospitalized due to right hemiparesis. Brain image showed cerebral infarction at the middle cerebral artery and echocardiography demonstrated vegetation at the mitral valve. She was successfully treated with embolectomy and parenteral antibiotics without any neurologic sequelae. This report shows that the early retrieve of septic cerebral emboli can be a helpful treatment of acute stroke associated with endocarditis.
