A Case of Tsutsugamushi Disease Complicated by Meningoencephalitis / 감염

Scrub typhus can invade central nervous system. The most common findings of CNS involvement are those of low grade meningitis, however, meningoencephalitis with coma and generalized seizure are also reported to occur in scrub typhus but only rarely. A 47-year old male was admitted to our hospital because of consciousness disturbance. The patient had a fever and rash for seven days before admission. He had been treated for diabetes mellitus for three years. Generalized seizure occurred six times after admission. CSF revealed increase of leukocytes (648/mm3) and protein level, and diffuse slow wave was found on electroencephaolography. The magnetic resonance image of the brain showed dural thickening. We diagnosed his illness as tsutsugamushi disease complicated by meningoencephalitis. After treatment with clarithromycin and an anticonvulsant, he recovered without neurological sequelae. O. tsutsugamushi should be considered as one of the causes of meningoencephalitis in endemic areas.

A Case of Cerebral Infarction Caused by Tumor Emboli from the Site of

Multiple cerebral infarction developed in a 36-year-old woman with adenocarcinoma of the right lung with direct cardiac invasion. Neurological examination and brain MRI showed findings of ordinary infarction. Transesophageal echocardiography showed left atrial pedunculated mass which was the potential source of embolism. We report a rare case who had such multiple spontaneous tumor emboli large enough to result in clinically detectable cerebral infarction.

A case of Tetranychus urticae - induced asthma in an inhabitant around pear orchard / 천식및알레르기

There have been a few reports of occupational asthma caused by Tetranychus urticae in fruit farmers or greenhouse workers. We report a case of bronchial asthma induced by Tetranychus urticae from a pear orchard in Cheonan city. An 18-year-old female student living around a pear orchard suffered from intermittent cough, rhinorrhea, and dyspnea for the 3 years. Her PC20 -methacholine was 0.15mg/ml, and skin prick test done with 55 inhalant allergens showed negative responses except Tetranychus urticae extract which was prepared with highly parasitized pear leaves. Bronchial provocation test with Tetranychus urticae extract showed a dual asthmatic response. These findings indicate that Tetranychus urticae, which include parasites in fruit trees, herba,ceous plants, and greenhouse cultures, can cause IgE-mediated bronchoconstriction in Korea.
