The incidence of vector-borne infectious diseases is increasing due to developments in diagnostic techniques, as well as due to economic, environmental, and ecological factors such as global warming, increased rainfall, globalization, and urbanization. Tick-borne infectious diseases occurring in Korea include severe fever with thrombocytopenia syndrome, Lyme disease, anaplasmosis, and Japanese spotted fever. Various skin lesions, such as erythema migrans, tick bite sites, rash, and eschar, are associated with tick-borne infectious diseases. It is necessary to remove ticks immediately to prevent transmission of these tick-borne infectious diseases. Especially for conditions such as Lyme disease, at least 24 to 48 hours of tick attachment to the host is required for transmission of the causative pathogens to the host. Tick-borne diseases are acquired after outdoor activities and have nonspecific symptoms such as fever, headache, and chills, which make them difficult to identify without a diagnostic test. Rapid diagnosis and early treatment can reduce the otherwise significant morbidity and mortality associated with these conditions; therefore, therapy should not be delayed until laboratory confirmation is received.

Pernicious anemia is a macrocytic anemia that is caused by vitamin B12 deficiency, itself a result of the absence of intrinsic factors due to autoimmune destruction of parietal cells. We report here the case of a 43-year-old female with spontaneous remission of pernicious anemia. The patient presented with fatigue. Her serum vitamin B12 level was low, hemoglobin level was 7.6 g/dL, and serologic tests for anti-intrinsic factor and anti-parietal cell antibodies were positive. We diagnosed her with pernicious anemia, but did not administer vitamin B12 because her hemoglobin level increased spontaneously. Since then, the patient's hemoglobin and serum vitamin B12 levels have been within the normal range.

BACKGROUND/AIMS: Recently, many cases of vitamin K-dependent coagulopathy of unknown origin have been reported. Such patients lack any relevant family history and have no systemic disease, raising suspicion of superwarfarin intoxication. We evaluated individual risk factors causing coagulopathy and hemorrhagic symptoms in patients with suspected superwarfarin intoxication. In addition, we determined how to effectively treat vitamin K-dependent coagulopathy caused by suspected superwarfarin intoxication. METHODS: Seven patients with suspected superwarfarin intoxication who lacked any definitive history of rodenticide ingestion were included. Thirty-one patients initially diagnosed with rodenticide poisoning were also included. We performed a retrospective chart review of all subjects and examined clinical data including patient demographics and medical histories. RESULTS: Patients initially diagnosed with rodenticide poisoning were divided into two groups, one of which had a laboratory abnormality (prothrombin time [PT] > 13 seconds) and another group with PTs in the normal range. There was no significant difference between the two groups in any of age, gender, the extent of chronic alcohol consumption, the causative rodenticide, psychiatric problems, ingestion of drugs interacting with warfarin, the extent of intoxication, or the type of ingestion attempt. The albumin level of the former group was significantly lower than that of the latter group (p = 0.014). Furthermore, a significant difference between the two groups was evident in terms of simultaneous ingestion of rodenticide and alcohol (p = 0.023). CONCLUSIONS: Most patients with superwarfarin poisoning did not exhibit any complication. When such complications were evident, they were associated with serum albumin level and coingestion of rodenticide and alcohol.
