JOURNAL FREE ACCESSThe clinico-virological association between sixty-six patients with primary infection of herpes simplex virus type-1 (HSV-1) treated from 1975 to 1981 (the first period ; FP) and eighty-six patients with primary infection of HSV-1 treated from 1982 to 1991 (the second period ; SP), as well as between child and adult groups of the SP was assessed. The results were as follows:
1: The male to female ratio is 1.0: 1.28 in FP and 1.0: 1.69 in SP, showing an increase of females from FP to SP. The tendency of the increase in cases in their thirties is especially apparent. As for age, the adults were found to increase in the SP (64%) while children under ten years old were found to decrease in the SP (16%).
2: As for the infection pathway within each family, infection between children was mainly in the FP while that between parents, especially the mother, and children was mainly in the SP.
3: As for patients condition, children tendded to show more severe symptoms than adults. Most prodromes were fever greater than or equal to 38 °C, and most physical conditions at the first examination were fever and/or painful swelling of the submandibular lymph node. The lesions in children occurred in the front of the oral cavity, while those in adults occurred in the back part of the oral cavity.View full abstractDownload PDF (6537K) -

JOURNAL FREE ACCESSCervical auscultation (CA) is used frequently in the clinical assessment of dysphagia. Abnormal swallowing and respiratory sounds during dysphagic swallows can be heard by cervical auscultation. However, assessment by CA is based on subjective evaluation. This study was designed to evaluate quantitatively the swallowing and expiratory sounds for distinguishing dysphagic swallows from normal swallows.
Fourteen glossectomized patients were examined. Patients swallowed 5 ml of barium several times. The swallowing and expiratory sounds were detected and recorded with videofluorographic (VF) images of these swallows and expiratory events. From the VF data, the analyzed sounds were classified into three groups ; Safety (sounds produced during safe swallows), WA (sounds produced during swallows with aspiration) and WP (with penetration). The mean durations of the swallowing sounds of WA (9.01 sec) and WP (12.06 sec) were significantly longer than that of Safety (0.60 sec). Comparison of the differentiation using the critical duration with the VF data (Safety/WA or WP) showed significant agreement in both areas. In the frequency domain analysis, the averaged magnitude of each frequency band from 0 to 1000 Hz of the expiratory sounds of WA and WP were significantly greater than those of Safety. Comparison of the differentiation using the critical magnitude of a frequency band from 0 to 250 Hz of the expiratory sounds with the VF data showed significant agreement in both areas. These results suggest that acoustic characteristics of the swallowing and expiratory sounds can be used as a clinical tool for detecting dysphagic swallows.View full abstractDownload PDF (4189K) -

JOURNAL FREE ACCESSNumerous methods are available for mandibular reconstruction following composite resection. Success of mandibular reconstruction is measured not only in terms of tumor control and survival but also in final cosmetic and functional rehabilitation. Twenty-four mandibles had been reconstructed temporarily using AO plate at the Department of Oral and Maxillofacial Surgery, Kurume University School of Medicine since 1984.
Among 24 patients, 15 males and 9 females, 16 were successfully treated and 8 were not, therefore, the overall success rate of mandibular plate reconstruction was 66.7 % and the mean follow-up period was 43.5 months (12 to 120 months). Ten patients (41.7 %) had postoperative complications, including 29.2 % of infection, 20.8 % of plate exposure, and 20.8 % of bone loss, hence 2 were cured conservatively and 8 plates were removed. The incidence of postoperative complication was significantly higher when the area had been irradiated preoperatively at the dose of 30 Gy or more. Reconstructed mandible with AO plate and free bone graft was unsuccessful in three cases. On the other hand, AO plate reconstruction combined with or without flap was not concerned with success rate.
In conclusion, the use of an AO plate should be limited only when the mandible is not irradiated over 30 Gy and when there is a possibity of soft tissue covering the plate.View full abstractDownload PDF (8341K) -

JOURNAL FREE ACCESSClinico-statistical study was carried out on 248 patients who underwent orthognathic surgery at the Second Department of Oral and Maxillofacial Surgery, Osaka University from 1977 to 1994. The results were as follows:
1. Male to female ratio was 1: 1.89.
2. The average age of male patients was 22.6 years old and 22.4 years old for female.
3. The diagnosis of mandibular prognathism was made for most patients. Twenty-seven patients (10.9 %) also had cleft lip and/or palate.
4. Sagittal split osteotomy was carried out on about 80 % of the patients.
5. The average operation time for sagittal split osteotomy was 184.5 min. and for simultaneous osteotomy was 259.4 min.
6. The average blood loss for sagittal split osteotomy was 575.4 ml, and for simultaneous osteotomy was 757.2 ml.
7. Recently screw osteosynthesis was carried out after using a repositioning system on the proximal segment.
8. Tongue reduction was carried out in 28 patients.View full abstractDownload PDF (732K) -

JOURNAL FREE ACCESSA clinicopathological analysis was made on 43 cases of squamous cell carcinoma of the tongue, which were treated at the First Department of Oral and Maxillofacial Surgery, Nagasaki University School of Dentistry from 1984 to 1995. The clinical stages of these cases were defined as follows: 10 cases were classified as stage I, 13 cases as stage II, 11 cases as stage III, and 9 cases as stage IV. Their five-year cumulative survival rates were 100 %, 72.7 %, 62.5 %, and 40 %, respectively.
These cases were classified into degrees of histological malignancy according to the Anneroth classification, and the relationship of the degree of histological malignancy with the prognosis was examined. The material was analyzed by 6 parameters: degree of keratinization, nuclear polymorphism, number of mitoses, pattern of invasion, stage of invasion, and lympho-plasmocytic infiltration. Each parameter was classified into 4 grades according to morphology.
Total score for each parameter ranged from 8 to 17, and the average score was 11.5. The materials were classified into three groups according to the total score: low malignancy group, moderate malignancy group, and high malignancy group. Their five-year cumulative survival rates were 83.3 %, 76.5 %, and 0 %, respectively.
A close correlation was found between the prognosis and the following parameters: pattern of invasion, stage of invasion and lympho-plasmocytic infiltration. However, no statistical significance was found between the prognosis and the following parameters: degree of keratinization, nuclear polymorphism and number of mitoses.View full abstractDownload PDF (720K) -

JOURNAL FREE ACCESSCoffin-Lowry syndrome is a rare heritable disorder with a characteristic phenotype. A 16-year-old female was requested oral examination on suspicion of Coffin-Lowry syndrome due to her characteristic clinical features: mental retardation, growth disturbance, large soft hands, pectus carinatum, lax ligaments, hypertelorism, square prominent forehead, broad nasal bridge, thick nasal septum, thick prominent lips with a pouting lower lip, and large protruding ears. Radiological study of hands showed drumstic-shaped fingers. She also exhibited malocclusion, deep central lingual groove, short root of teeth, conical teeth, taurodontism, and congenital missing teeth. The final diagnosis was Coffin-Lowry syndrome based on the above findings.View full abstractDownload PDF (8354K) -

JOURNAL FREE ACCESSA case of a recurrent calcifying odontogenic cyst with immunohistochemical finding was reported. Apparently, the reactions to tenascin and KL-1 (cytokeratins) were stronger in the initial lesion than in the recurrent lesion around ghost cells and calcified bodies. The initial lesion contained many calcified bodies and had an indefinite cyst wall, while the recurrent lesion contained of a few calcified bodies and had a rigid cyst wall. In the recurrent lesion, the ratio between basal cells and calcified bodies is much higher than that in the initial lesion, which may induce the transformation into tumor.View full abstractDownload PDF (8778K) -

JOURNAL FREE ACCESSSialolith usually occurs in the submandibular gland and its occurrence in the parotid gland is relatively rare. Especially the occurrence of sialoliths in the bilateral parotid gland is very rare and only three cases of such a case have been reported. In this paper, a case of sialolithiasis occurring in the bilateral parotid gland was reported.
The patient, a 65-year-old Japanese male, visited our clinic complaining of swelling of the right buccal mucosa including the orifice of the parotid duct. Roentogen examination revealed the presense of sialoliths in the right parotid duct and the deep lobe of the left parotid gland. Extirpation of the sialoliths of the right parotid duct was performed under local anesthesia, and 6 sialoliths of 2 mm or less in diameter were observed. Though extirpation of the left sialolith was not performed because of lack of objective and subjective symptoms, long-term follow up is considered nessesary.View full abstractDownload PDF (3662K) -

JOURNAL FREE ACCESSIt is important in deciding therapeutic procedures for patients with ankyloglossia to evaluate age, degree of ankyloglossia, and functional disorders. However, it is often found that frenulectomy had been performed in early infancy without sufficient functional diagnosis.
In this paper, a case of a 6-year-old female, in which ankyloglossia had been first diagnosed at 9 months of age, whose articulation disorder was the substitution of/t/for/k/and/d/for/g/, which did not result from ankyloglossia, was reported. The therapeutic procedure was decided not to be frenulectomy but speech therapy. Speech therapy was very effective in this case, and articulation disorder was improved after 2 months.
The result of this case suggested that frenulectomy in infancy should not be performed only based on the diagnosis of the morphology of the lingual frenulum if there is no disturbance in sucking and that it is important to assess the propriety of frenulectomy from the viewpoint of speech pathology for patients with ankyloglossia complaining of articulation disorder.View full abstractDownload PDF (3523K)
