Stands of Sugi, Cryptomeria japonica, and Hinoki, Chamaecyparis obtusa, produce 1014 pollen grains per ha per yr in a productive year and 1011-1012 grains in an unproductive one. Little year-toyear fluctuation in pollen production by stands of pioneer and secondary trees is evident, the maximum/minimum ratio within a stand being about 2. In comparison, alder stands produce 2-5×1013grains in both productive and unproductive years. Pollen production rates of Sugi stands increase with increasing age of the stand until 50 yr, showing a constant upper limit for several hundred years thereafter. With regard to year-to-year fluctuations in pollen production rates for Sugi stands, annual rates alternate from high to low every year. This rhythm may be interrupted by the accidental effects of unusually hot dry weather in late June and July. The amount of pollen dispersed into the air can be predicted from the number of male flower buds that fall before flowering in autumn and winter. Control of pollen production in forests by silvicultural techniques while paying attention to the environmental conservation of forests is considered extremely difficult.

We report a rare case of intraoral foreign bodies.A 61 year-old woman felt pain in the oral cavity immediately after eating fresh squid and visited our hospital.We diagnosed as intraorl foreign bodies on examinations, since many white spindle shaped foreign bodies were observed in her oral cavity. We removed these foreign bodies with perimucosal tissue using forceps. The microscopic examination revealed the foreign bodies were the sperm bulb of the fresh squid.We emphasized that fresh squid should be eaten with care.

The vibration of the body wall during phonation was measured using accelerationtype pick-ups attached to five different points on the body wall. The voice was recorded simultaneously. The test subjects were 18 amateur singers. Each subject was asked to phonate five Japanese vowels /a/, /i/, /u/, /e/ and /o/ in both trained singing voice (trained voice) and untrained singing voice (untrained voice). This distinction was possible for all subjects after some practice.Spectral analysis of the body wall vibration was performed. The intensities of the vibration were also analysed with respect to the vibration proportion (VP), which is the ratio of the body wall vibration (G) to the sound pressure level. 'Singing formant'was found not only in the spectral structure of the voice sound but also in that of body wall vibration. The VP of the cheek was greatest with the trained head voice, but it was not so great during the production of trained chest voice. With the untrained voice, there was no difference in the VP among the five locations of the body wall. The VP at the cheek in music students was greater than that of members of a glee club. The difference of VP among five vowels was smaller with the trained voice than with the untrained voice. These results suggest the important role of the vibration of the cheek and great resonance of oral cavity in the trained voice.Listening tests were also performed. Five vowels of voice sound that had been recorded simultaneously with the vibration of body wall were presented to a group of 18 listeners for identification. Articulation score for trained voices was lower than that for untrained voices. The difference of articulation score among five Japanese vowels was smaller with the trained voice.These results suggest that the difficulty in perceiving sung vowels arises from ‘covering’.

We encountered two cases of otomyiasis. The first case involved left external auditory meatus myiasis due to Sarcophaga peregrina (Robineau-Desvoidy,1830) in a baby girly approximately two months old. The second case was right external auditory meatus myiasis due to Sarcophaga similis Meade,1876, in a six-year-old girl. Both cases occurred in September 1993.Previously myiasis was more common. Antimicrobial therapy and amelioration of public health has resulted in a decrease in the number of myiasis cases. Today, it is quite rare.Recently, twelve cases of genuine myiasis have been reported in Japan. We report two cases of otomyiasis.

Foreign bodies in the paranasal sinus are not rare in the field of otorhinolaryngology. Here we report a case of a foreign body retained the paranasal sinus for 13 years.The patient was a 26-year-old woman whose chief complaint was postnasal drip. Thirteen years earlier, she had fallen from a bicycle into a bamboo thicket and a piece of bamboo had pierced the outer part of the right root of the nose. She had undergone operqtuon to remove the bamboo by an external incision, but a residual foreign body was observed by CT. We removed the foreign body by radical surgery on the paranasal sinus. Postoperative CT showed no residual foreign body and the course was good. There were no complications such as oculomotor disturbances before or after surgery.This case is reported as a patient with a long-term foreign body in the paranasal sinus. Some discussion of the literature also presented.

The total number of the cases was 437. The site of the foreign bodies was the ear (141), nose (94), oral cavity and pharynx (101) esophagus (84), trachea and bronchus (17).The most frequent foreign bodies in the ear were toys in children under 5 years old and insects in adults.The insects were common from July to September.The most frequent foreign bodies in the nose were toys in children under 10 years of age.The foreign bodies in the oral cavity and pharynx were mainly found in the oropharynx. Fish bones were most common.Most of the foreign bodies of the esophagus were found at the cricopharyngeus.Coins were the most frequent foreign bodies in children. Fish bones and prosthesis were the main foreign bodies in adults.Most of the foreign bodies of the trachea and bronchus were in children under five years of age. There was no marked difference infrequency between right and leftbronchus.

Six patients with cysts in the posterior paranasal sinuses who compained of visual disturbance are reported. All of them had previously undergone sinus surgery (mean,20.3years). All of them were treated via an endonasal approach under local anesthesia. In five, the visual acuity and the visual field was improved after surgery. However, one did not recover the visual field despite gross improvement in the visual acuity. Computed tomography was very useful to localize the lesion, and the image amplifier was useful to indicate the sphenoid sinus.

Though many different pathologies cause vomiting, they can be divided into three categories. The first is vestibular vomiting such as that caused by motion sickness. The second is vomiting mediated by chemoreceptor trigger zone (CTZ) in the area postrema, such as that seen in poison-induced vomiting. The third is vomiting from the gastro-intestinal tract. Vestibular stimuli, signals from the CTZ, and afferent signals from the gastro-intestinal tract stimulate the vomiting center in the medulla to cause vomiting independently.Histamine H1-blockers (diphenhydramine, promethazine) prevent vestibular vomiting selectively. Dopamine D2-blockers (metoclopramide, domperidone) act on the CTZ to inhibit CTZ-mediated vomiting. Serotonin 5-HT3-blockers block afferent signals from the stomach induced by cisplatin. Diphenidol may inhibit the vomiting center because diphenidol prevents both motion and cisplatin-induced vomiting.

Vogt-Koyanagi-Harada disease has been described as an autoimmune disease which targets melanocytes and causes visual disturbance. In addition, it causes auditory and equilibrium disorders occasionally. In this study, we report a case of Harada's disease with sensorineural hearing loss.A 51-year-old male visited Aichi Medical University complaining of visual and hearing disturbances. An audiogram demonstrated moderate sensorineural hearing loss bilaterally. Visual and auditory acuity improved after administration of steroids. The hearing disturbance in this case may have been caused by an autoimmune reaction to melanocytes in the inner ear, similar to the previously reported phenomenon in the eye.

A 93-year-old man with bilateral mild hearing loss since childhood due to chronic middle ear infections could hear and speak as an adult, but his hearing level had gradually become worse. He started to wear hearing aids when he was 70 years old, but he still found it difficult to hear. Finally, he could not understand the contents of any conversations by 87 years old, even with hearing aids. He accepted to undergo cochlear implantation on the right side at the age of 93 years. The results of the speech recognition test improved after surgery for monosyllables (from 28% to 38%) and single words (from 18% to 38%), but no improvement of sentence recognition was observed. Oldest-old patients have little occasion to speak, and could benefit from special tools, such as an audiobook or DVD, which they can learn by themselves.

One hundred ninety eight patients with Reinke's edema who visited our clinic between 1981 and 1990 were retrospectively studied. One hundred twenty four were males and 74were females. Ninety percent of the patients were between 30 and 69 years old. Brinkman's index was 400 or more in 78% of patients. This suggests that smoking was the most important etiological factor. Surgery was performed for 73 cases and the hoarseness improved in 63 cases. Thirty one patients stopped smoking for more than a month without surgery, and 16 cases showed vocal improvement. Surgery was effective regardless of the size of the lesion, while prohibition of smoking was effective only for slight edema. Voice therapy without surgery or prohibition of smoking had no effect on hoarseness.

We report a patient with traumatic perilymphatic fistula caused by an earpick. Exploratory tympanotomy was performed via endoaural incision. The patient was found to have a dislocated stapes in the vestibule. The stapes was removed, and no perilymphatic leakage from the oval window was seen. Jugular pressure was also performed with no lymphatic leakage. We then injected physiological salt solution at 37°C into the oval window. Lastly, stapes surgery was perfomed and a piece of fascia was placed over the perforation in the tympanic membrane using fibrin glue. The patient's operation was performed 3 days after trauma and improvement of vertigo and hearing (sensory and air-bone gap) was obtained after surgery.

We encountered a case of hyoid bone elongation characterized by a clicking sound on swallowing. A 32-year-old man complained of a foreign body sensation and painless clicking sound on the left side of his neck when swallowing. CT scan of the neck revealed that the left greater cornu of the hyoid bone was elongated. Both greater cornu were surgically removed, and his symptoms disappeared.

A new theory of sound analysis in the auditory system is proposed. The main function of the inner ear is not frequency analysis but transformation of acoustic information into impulses in the auditory neurons. An impulse evoked by sound stimulations in the inner ear has only two kinds of information, that is,1) “when” and 2) “in which neuron” it was evoked. The accuracy of the information is guaranteed by hair cells having the function of “phase locked” response to traveling waves and being aligned on the basement membrane.These two kinds of information can be analyzed as precisely as is needed by the convergences and the divergences of neurons in the central auditory system. The nature of “tonality” in the auditory system is the inevitable attribute of the theory of sound analysis I propose, which is called “Wavelength Theory”. The resonate nature of the basement membrane functions to transform the sound intensity into the total number of impulses evoked in the inner ear. There is a conflict in “Place Theory” with respect to the insufficient transformation of the sound intensity.

We report two cases in which drooling was reduced by percutaneous use of scopolamine ointment. Case 1: A 75-year-old female patient with amyotrophic lateral sclerosis (ALS). In addition to low-pressure continuous suction of the mouth, she was started on scopolamine ointment applied over the postauricular region. Before the ointment was prescribed, the volume of continuous suction was 400 ml/day, whereas it decreased to 150 ml on day 1 and to 200 ml on day 2 after the start of ointment application. Case 2: A 17-year-old female patient with cerebral palsy. If the score on Numeric rating scale (NRS) for the caregiver’s burden before the start of ointment application was 10, the score decreased to 2–4 after 4 hours and 1–3 after 24 hours of ointment application. Two and a half days after the ointment application, there was an objective increase in the amount of saliva, so that the application interval was shortened from every 3 days to every other day. Thereafter, there was a consistent decrease in the amount of saliva. Scopolamine is known to have side effects such as dryness of the mouth, drowsiness, blurred vision and mydriasis, constipation, and urinary retention. However, even after several months of use, no side effects have been observed in either case. We present some review of the literature, including on instructions for preparing and using scopolamine ointment.

Positional alcohol nystagmus (PAN), alcoholic gaze nystagmus (AGN), trunkal ataxia and other oculomotor abnormalities are well-known behavioral changes that follow alcohol ingestion. This paper reviews previous work concerned with these alcohol-induced behavioral changes, including our recent work. We cofirmed that PAN could be elicited by even low blood alcohol concentrations (BAC was 0.02%) and two different types of the form were observed to arise chronologically (PAN I and PAN II). Moreover, a significant linear relationship was found between the intensity of PAN and BAC. When trunkal ataxia was measured with a stabilometer, the circumscribed area of body sway showed the closest correlation with BAC. Other analyses of body sway failed to find any characteristic features of alcohol-induced trunkal ataxia.

Three hundred and eighty children were diagnosed as “delayed speech and language development” at our speech clinic in Kinki University Hospital from 1977 to 1989. To investigate the language abilities and the possible causal factors of these children as a group, medical records and speech and language records including case histories of each child were reviewed and statistically analyzed.At the first referral,77 % of the children were under age 6, and 51% were between ages 2 1/2 and 4 1/2 years old. The incidence was higher for the boys than the girls at the ratio of three to one. The average onset of walking was 17 ± 8.0 months, and the average onset of speech was 20.5 ± 11.6 months. Seventy percent of the subjects were normal in their communicative manners,10% were autistic and 20% were in-between.Language abilities were evaluated by using a five level scale, which was proposed by the Committee of Delayed Speech and Language Development in the Japanese Society of Logopedics and Phoniatrics. Abilities of receptive language and of expressive language were evaluated separately. In both abilities, more than one third of the subjects were evaluated at level 3, that is, the child points at the picture card when the object shown on each card is mentioned, or a child answers the name of the object or picture shown to him.Seventy five percent of the subjects showed some kind of anomalies or deficiencies besides speech and language deficiencies. Mental retardation was seen in 43% of the subjects.

Group pure tone screening test was performed on kindergartners to efficiently screen for hearing disorders. Pure tones of 500,1000 and 4000 Hz in each ear were combined with a hand raising response. The test frequency of 500 Hz was added to screen for otitis media.<BR>About 80% of children over 3 years and 6 months of age were capable of takin g the group screening test with hand raising response. At the same time, the ratio of children who could pass the screening test also increased considerably from 45.2% to 65.2%.<BR>Although we used 500 Hz to screen for otitis media, it was difficult to di a g nose otitis media by hearing screening only. Therefore, hearing screening was mainly effective in determining moderate hearing loss and unilateral sensorineural hearing loss.<BR>We found that a well-planned screening procedure and preparation b e fore the screening as well as decrease in the fail one rate on initial screening are necessary to examine large numbers of children rapidly and screen hearing disorders efficiently.
