In the years 2000 and 2001, we have researched the correlation between C. japonica and Cupressaceae pollen counts, and the number of patients with Japanese cedar pollinosis treated at nose and ear clinics, and the correlation between the dosage of medicine prescribed and OTC by the same drugstores in Fukuoka City. Similarly, we tried to find the relationship between grass pollen count, number of the pollinosis patients and the dosage of drugs among the patients too. The conclusions are as follows :
(1) The dispersing peak of C. japonica pollen appeared between the end of February and early in March, Cupressaceae between the end of March and early April. Gramineae pollen grains dispersed mostly in the middle to the end of May.
(2) A significant correlation was obtained between the previous week pollen counts and the number of patients during only C. japonica pollen grains were dispersed.
(3) In the year 2001, total pollen counts of C. japonica and Cupressaceae pollen were about 8 times higher, the number of patients with pollinosis was about 2 times more. The amounts of prescribed medicine and OTC were about 2 times higher than the previous year respectively.
(4) As for a correlation between weekly pollen counts of C. japonica and next the weekly number of dosages and containers of each drug per week, there was a significant correlation between the pollen counts and anti-allergic internal medicine.
(5) A very significant correlation appeared between the weekly number of patients with Japanese cedar pollinosis and the weekly dosage of most medicine except antihistamines.
(6) Though the pollen counts of Gramineae was very small, the grass pollinosis patients were consulted until May, and the exacerbation of grass pollinosis worsened with relative increasing grass pollen.
(7) The more useful pollen information can be made by studying the relationship during causative airborne pollen counts and the number of patients with pollinosis and the amount of medicine for treatment at the drugstores in Fukuoka City.

Reconstruction surgery, is being used increasingly to treat large T3 and T4 cancers of the tongue. For small T1 and T2 tumors, treatment is roughly divided into partial resection and a sealed small radiation source. We have been treating patients with cancer of the tongue since 1946. Primary lesions were mainly treated by a radium small radiation source until the early 1980 s. Clinical results from 1946 to 1970 were not satisfactory, with 5-year-survival being T1 : 69.9% (N=136) and T2 : 52.9% (N=231). Because calculation of radiation dose distribution using a computer was introduced and also because dissection of the neck was conducted positively against cervical lynphnode metastasis, 5-year-survival from 1971 to 1980 improved to T1 : 79.2% (N=63) and T2 : 69.0% (N=78). In 1982, the number of surgical cases increased gradually even for Tl and T2 as reconstruction using a skin flap was begun. In 1994, treatment with a small radiation source was abolished with closure of the radiation control ward. After that, we conducted treatment based mainly on partial resection. Subjects were 283 patients with stage I and II squamous cell carcinoina of the tongue who underwent radical therapy from January 1982 to December 1996, classified by therapy. In the small radiation source group, local recurrence, neck recurrence, and 5-year-cumulative survival by the Kaplan-Meier method were 15.5%, 39.7%, and 84.5% in stage I (N=58) and 15.5%, 43.1%, and 74.1% in stage 11 (N=58). In the surgically treated group, they were 14.7%, 21.3%, and 74.5% in stage I (N=75) and 14.3%, 40.5%, and 78.0% in stage II (N=42). No significant difference was found in results by to therapy. In the integrated treatment groups, 5-year-cumulative survival in stage I was 78.3% (N=143) and in stage II 71.2% (N=140).

We studied 134 ears with clinical otosclerosis operated on from 1984 to 2000, focusing on clinical features and hearing improvement.
Male patients numbered 48 (53 ears) and female 73 (82 ears). The male to female ratio was 1 : 1.5.
Small fenestra stapedectomy was conducted on 118 ears, partial stapedectomy on 11 and total stapedectomy on 5.
Some 97% of operations were successful based on the guideline in reporting hearing results in middle ear and mastoid surgery (2000). We feel that a guideline is needed in stapes surgery.
No serious complications were seen.

We report a patient with vertigo and acute sensorineural hearing loss due to infarction involving the anterior-inferior cerebellar artery (AICA). A 65-year-old woman reporting sudden-onset vertigo and severe unilateral hearing loss without other neurological deficits had a history of hypertension. Neurootological examination showed a rotatory, positional, spontaneous, and gaze nystagmus toward the left. Right facial and trigeminal nerve paralysis appeared 2 days later. Based on these findings, we suspected a brain stem lesion. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a pontine infarction in the AICA, so the patient was diagnosed with AICA hearing syndrome. In some cases, the clinical signs of AICA syndrome are similar to those of inner ear disorders. Neurootological signs, nystagmus, and MRI are clinically useful in distinguishing AICA syndrome from inner ear diseases.

A 17-year-old man with an aneurysmal bone cyst that arose in the frontal bone reported swelling in the forehead, and on initial examination, an elliptical mass about 5 X 5 cm and 2 cm high was seen in the center of the forehead. There was no history of trauma or similar events. Magnetic resonance imaging disclosed an elevated, multilocular lesion with intracystic fluid formation. Surgery involved curettage, follwed by repair of the frontal defect using artificial cranial bone, and blockage of the communication with the nasal cavity using a forehead flap. Histopathological examination revealed cyst formation, osteoblasts, and multinucleated giant cells without much dysplasia. Given the patient's age and histopathological findings, the lesion was diagnosed as an aneurysmal bone cyst. The patient remains recurrence-free about 2 years after surgery.
