Inhalation of buckwheat flour as well as ingestion of buckwheat foods induces bronchial asthma. The buckwheat flour attached to the husks used as bed pillow filling can provoke bronchial asthma in patients sensitized to buckwheat. In Korea one third of the pillows contain buckwheat husk (BH). Recently the authors examined three asthmatics who presented symptoms when exposed to house dust extract and BH-pillow extract. They had no history of asthma attack following ingestion of buckwheat foods. The possibility of mites or mite like substances in the BH-pillow extract was evaluated. There was a good correlation of skin test results between Dermatophagoides farinae (D. farinae) and BH-pillow extract. The concentrated extract of BH-pillow displayed inhibition of D. farinae radioallergosorbent test (RAST) and a dose dependent pattern RAST inhibition. The lyophilized extract of BH-clean did not show any constant feature in D. farinae RAST inhibition test. Furthermore, mites of Dematophagoides species were discovered in the contents of BH-pillows. Ten of 40 cases who tested positive to the skin test for the extract of BH-pillow manifested weakly positive to buckwheat RAST. None of them presented a previous history of buckwheat food allergy. Also we evaluated the possibility of cross-allergenicity between buckwheat and its husk. Using these results the authors concluded that there were some amounts of allergenic substance from house dust mites in the contents of BH-pillows and that the dust from these could provoke or aggravate the symptoms of asthmatics who were sensitive to house dust mites.

"Tumor-to-tumor" metastasis is a rare event; meningioma has been reported as the most common primary intracranial tumor to harbor cancer metastases. Several hypotheses have been previously proposed to explain this occurrence, but the exact mechanism by which these metastases develop into meningiomas is not yet understood. Magnetic resonance imaging and spectroscopy have been valuable diagnostic tools, but preoperative diagnosis of metastasis to meningioma remains highly difficult. We present a case report of a metastasis of non-small cell lung cancer into an intracranial meningioma.

A daily count of air borne pollen was done within the city limits of Seoul, Korea for a period of two years (1984-1985) using Durham's Gravity Sampling Device. Two major pollen seasons, March through May, and the month of September, were easily distinguishable. The concentration of the different types of pollen as well as all of the pollens combined varied similarly both years to a significant degree. The pollen types found in the greatest numbers were Alnus (March), Populus (April), Quercus (April-May), Pinus(May), grasses (September), and weeds (September). The main weed pollens detected in September, sagebrush, ragweed and Japanese hop would also be considered to be important allergenic pollens of respiratory allergy in Korea. The results of the survey are discussed in the light of especially relevant published literature.

In Korea, there are two descrite pollen seasons: a tree pollen season and a weed pollen season. In order to investigate the incidence of sensitization to the major pollens and to evaluate is clinical significance in respriatory allergic disease, skin prick tests were performed using 7 species of Korean pollen extracts (K-P extracts) and specific IgE was measured by the Phadebas radioallergosorbent test (RAST) in patients with positive skin prick tests. Of the 317 patients with respiratory allergic diseases 73 patients (23.0%) were skin prick test positive to one or more K-P extracts and the positive reactions to individual pollens were as follows: 14.2% (45/317) positive to sagebrush 10.4% to ragweed, 5.0% to grass, 4.1% to oak, 3.8% to alder, 1.9% to poplar; and 0% to pine. The 30-39yr old group manifested the highest skin test positivity 36.7%. There was no difference in the skin reactivity according to the patient's sex and the kinds of allergic disease. Also there was no relationship between birth season and skin test positivity. The agreement between the results of the skin prick test with K-P and commercially prepared Bencard's pollen extracts (B-P extracts) was good. There were good correlations between the strongly positive skin prick test and a posivite RAST and also between a netative skin prick test and a negative RAST. From this study, it can be concluded that overall sensitization rate of respiratory allergy patients to K-P exstracts was 23.0%, and that weed pollens such as sagebrush and ragweed were major pollens.

BACKGROUND: There are some reports that superficial cryotherapy of alopecia areata could be an effective mode of treatment with many advantages. OBJECTIVE: We retrospectively evaluated the efficacy and side effects of superficial cryotherapy in patients with alopecia areata. METHODS: We retrospectively reviewed the clinical records of 153 patients with alopecia areata, who had been treated with superficial cryotherapy for more than 4 weeks, during the twelve years since 1993. We then evaluated the efficacy of superficial cryotherapy and its relationship with various clinical factors and side effects. Superficial cryotherapy using liquid nitrogen spray for 2~3 seconds was applied to the alopecic patches, and repeated three or four times per session. Positive therapeutic response was defined as the regrowth of terminal hairs. RESULTS: The results are summarized as follows: Positive therapeutic responses were noted in 105 (68.6%) of 153 patients reviewed. Patients who responded, vellus hair appeared within 4 weeks of treatment, terminal hair within 7 weeks, and a marked recovery was achieved within 12 weeks. A relatively good response rate was obtained in those patients who had less than 4 weeks of treatment, and the area of treatment was less than one fourth of the total scalp area, or less than two alopecic patches. On the other hand, those over 50 years of age and with more than 3 weeks of treatment interval seemed to have a relatively poor response rate. Other factors were not significant. There were no significant side effects, except slight pain, swelling and erythema. CONCLUSION: Superficial cryotherapy in patients with alopecia areata can be an effective treatment modality. It is a simple and convenient method, and has relatively good therapeutic response with less side effects. Therefore, we propose the superficial cryotherapy as a first-line treatment for patients with a milder form of alopecia areata, especially in children who are vulnerable to therapeutic side effects and pain.
