Abstract
Oral mucositis is a dose-limiting toxic effect of radiotherapy and chemotherapy on oral cancer. The purpose of the present study is to assess the relationship between tumor response and oral mucositis in preoperative radiochemotherapy for oral cancer retrospectively. Fifty-four cases of oral squamous cell carcinoma were treated with concurrent radiochemotherapy prior to surgery. When oral mucositis was evaluated with the WHO scale, severe oral mucositis (Grades 3 and 4) developed in 22 cases (41%). A more than 50% reduction in tumor size was clinically observed in 38 cases (70%). From histopathological analysis of the surgical specimens all tumor cells observed appeared to be non-viable in 16 cases (29%). The cases with Grade 1, Grade 2, Grade 3 and Grade 4 oral mucositis included 33%, 62%, 85% and 89% of clinical good-response cases and 0%, 24%, 31% and 55% of histopathological good-response cases, respectively. This retrospective study suggests that severe oral mucositis promises a good response of oral squamous cell carcinoma to radiochemotherapy.

Abstract
BACKGROUND To date, many researchers in Japan have assumed that the cause of autistic spectrum disorders is attributable to some disorder in the ability of the child. However, we have been working on the premise that autistic spectrum disorders are brought about by relationship disturbances in early infancy and have been attempting to validate this hypothesis through early intervention. METHODS We have examined the developmental process of affective communication in infants with autistic spectrum disorders. We have postulated that approach-avoidance motivational conflict (Richer) is the primary factor impeding the development of affective communication and have focused therapeutic intervention on this perspective. RESULTS As a result, attachment behavior was markedly improved in children, but affective communication with their mothers was not. Examing the mothers' images of themselves in infancy in mother-infant psychotherapy, problems that the mothers had themselves in infacy with attachment behavior to their own mothers affected the mothers' internal representation of their children, leading to active evolution of mother-child interaction and development of affective communication between the mother and child. CONCLUSIONS In this context, the basis and significance of the internal representation of both parties being determinants in the quality of mother-child communication are discussed. Our goal in early intervention is not the elevation of a child's linguistic-cognitive abilities, but the creation of a comforting relationship in which both parent and child can live securely, without strain.

Abstract
Interleukin-1alpha (IL-1alpha) and matrix metalloproteinase-9 (MMP-9) are thought to be involved in odontogenic cyst expansion. In this study, we investigated the effects of IL-1alpha on the secretion and activation of MMP-9 in odontogenic jaw cysts. An active form of MMP-9 was present in odontogenic keratocyst (6 of 8 cases) fluids more frequently than dentigerous cyst (3 of 10 cases) and radicular cyst (3 of 10 cases) fluids, although proMMP-9 was present in all cyst fluids. Odontogenic keratocyst fragments in explant culture secreted a larger amount of IL-1alpha than dentigerous cyst and radicular cyst fragments in explant culture, and spontaneously secreted both proMMP-9 and an active form of MMP-9. The fragments of dentigerous cysts and radicular cysts secreted a small amount of proMMP-9, but no active form of MMP-9. Exogenously added recombinant human IL-1alpha (rhlL-1alpha) increased the secretion and activation of proMMP-9 in the fragments of dentigerous cysts and radicular cysts. The epithelial cells isolated from odontogenic keratocysts secreted IL-1alpha and proMMP-9 without stimulation. Under the cultivation on a fibronectin-coated dish, rhIL-1alpha increased the secretion of proMMP-9 from the epithelial cells in a dose-dependent manner. Moreover, rhIL-1alpha induced the secretion of proMMP-3 and plasminogen activator urokinase (u-PA) from the epithelial cells, and converted the secreted proMMP-3 to the active form in the presence of plasminogen. The secreted proMMP-9 was also activated in the presence of rhIL-1alpha and plasminogen. Hence, our results suggest that IL-1alpha may up-regulate not only proMMP-9 secretion but also proMMP-9 activation by inducing proMMP-3 and u-PA production in the cyst epithelial cells by autocrine/paracrine regulatory mechanisms.

Abstract
The Levandoski panographic analysis of routine panoramic radiographs was developed to improve the diagnosis of hyperplasia of the coronoid process. The ratio of the length of the coronoid process to the condylar process in the Levandoski panographic analysis has a linear relationship with that in the cephalometric analysis (r = 0.75, n = 59). The ratio in patients with hyperplasia of the bilateral coronoid process was significantly greater than that of the control on both sides (P < 0.01). Although the minimum value of ratio in the patients was 1.15, the maximum value of the controls was 1.07. These results show that the Levandoski panographic analysis is useful in the evaluation of hyperplasia of the coronoid process in adults. When a patient complains of limited mouth-opening and the ratio is more than 1.1, further investigations should be made to verify the diagnosis of hyperplasia of the coronoid process.

Abstract
OBJECTIVE The purpose of this study was to compare the dentocraniofacial morphology of parents of children with cleft lip and/or palate (CL/P) with that of parents of children without CL/P and to use the results for genetic counseling. PARTICIPANTS Twenty-five fathers and 40 mothers of Japanese children with CL/P, who also had relatives with CL/P within three generations (experimental group), and 413 pairs of parents of children without CL/P (control) were used in this study. To test the accuracy of the discriminant function, 165 subjects were added to this study (test group). MATERIALS AND METHODS Sixty-five dental casts were measured by digital sliding calipers, and 1056 frontal and 1056 lateral cephalograms were traced, digitized, and analyzed using analysis of variance (ANOVA) and discriminant analysis. RESULTS Mesiodistal tooth diameters in parents of children with CL/P did not show any differences from those in parents of children without CL/P. The parents in the experimental group showed a distinct craniofacial morphology: wider interorbital width (IO-IO'), intercoronoid process distance (Cp-Cp'), and nasal cavity width (NC-NC') and larger anterior cranial base length (S-N) and cranial base length (N-Ba). For genetic counseling, a discriminant function was obtained using four significant ratios on ANOVA. The percentage of correct classification using this function on the pooled experimental and control subjects was 67.9. CONCLUSION The parents in the experimental group showed a special craniofacial morphology, but the results suggest that the discriminant function might not be helpful in genetic counseling.

Abstract
OBJECTIVE The purpose of this study was to investigate the effect of interleukin-1 on cells from loose bodies of synovial chondromatosis of the temporomandibular joint. STUDY DESIGN The cells were isolated from uncalcified loose bodies in a case of synovial chondromatosis of the temporomandibular joint and cultured in alpha-MEM medium containing 10% fetal bovine serum. The cells were treated with or without interleukin-1alpha and then stained with toluidine blue. Their conditioned media were analyzed with gelatin zymography to detect matrix-degrading proteinase(s). RESULTS The cells from loose bodies produced toluidine-blue-stained matrix. When the cells were treated with 100 ng/ml of interleukin-1alpha for 3 days, toluidine-blue-stained matrix was strikingly reduced. Gelatin zymography revealed that interleukin-1alpha-treated cells released 62-kDa gelatinase. CONCLUSIONS Interleukin-1alpha may lead loose-body-derived cells to degrade the cartilaginous matrix of loose bodies in synovial chondromatosis of the temporomandibular joint.

Abstract
This article describes three cases of acute lymphocytic leukemia that presented with mental neuropathy, or so-called "numb chin syndrome," as the initial symptom of the disease. This symptom heralded the initial progression of the disease in the first and second cases and the recurrence of the disease in the third case. In these cases tenderness in the mental foramen, percussion pain of the teeth, loosening and extrusion of the teeth, and radiographic abnormalities were also, if not always, observed in association with mental neuropathy. The radiographic abnormalities included a disappearance of the mandibular canals, an enlarged periodontal ligament space, a loss or thinning of the lamina dura, and a destruction of the alveolar crestal bone. This report indicates that oral manifestations can therefore occasionally play an extremely important role in the early recognition of acute lymphocytic leukemia. The unexplained oral abnormalities such as numbness of the chin and lower lip must thus be considered, potentially ominous indication of acute lymphocytic leukemia.

Abstract
We report rare case of multiple pleomorphic adenomas arising in the parotid and submandibular lymph nodes of a 21-year-old man. These tumours were surrounded by lymphoid tissue which was almost identical to that of the cortex of lymph node. The possibility of metastasizing pleomorphic adenomas was discounted because the mitotic activity was low and there were no signs of infiltration. Heterotopic salivary gland tissue was also found in the lymph nodes that contained the tumours, and each tumour expressed a similar immunohistochemical staining pattern to that of the salivary gland tissue. These findings indicate that these pleomorphic adenomas probably arose from the salivary gland tissue within the lymph nodes.

Abstract
OBJECTIVE The age-related expression of the extracellular matrices in human mandibular condyle was examined. STUDY DESIGN The distribution patterns of types I to V collagens, laminin, fibronectin, fibronectin receptor, and transforming growth factor beta in 34 human mandibular condyles dissected from autopsy specimens were studied by immunohistochemical procedure with special attention on the age-related changes. RESULTS Type I collagen was detected in the full layer of the condylar cartilage, and a stronger immunoreaction was delineated in the articular and cartilage zone. Types II and III collagen were mainly localized in the fibrocartilage zone. Type IV collagen and laminin were detected not only in the basement membrane of the blood vessels but also in the degenerated lesion where the expression of transforming growth factor beta was also detected. Immunostaining of type V collagen and fibronectin was noted in the perichondrocytic area, whereas that of fibronectin receptor was seen in the chondrocytes. In materials from younger cadavers types I, II, IV and V collagens, fibronectin, its receptor, and laminin showed stronger expression in the degenerative lesions than in the normal portions. In the sections from cadavers over the seventh decade, the immunoreaction of extracellular matrices was weak compared with the younger materials, and no increased reaction of extracellular matrices in the degenerative lesions was detected. In addition, severe osteoarthrosis was frequently seen in the older materials in macroscopic findings. CONCLUSION These results suggest that the expression of extracellular matrices thus seems to be closely related to aging and degenerative changes in the condyle.

Abstract
PURPOSE This study determined the osteoarthrotic changes in the human mandibular condyle in relation to aging and the loss of dental occlusal contacts. MATERIALS AND METHODS Thirty-four condyles obtained at autopsy were studied morphologically, radiologically, and histologically. RESULTS With advancing age, the articular surface of the mandibular condyle morphologically showed severe degenerative changes. The condyles with these changes tended to be from the side of the mandible with minimal areas of occlusal contact. Radiographically, an irregularity of the cortical bone plate was most commonly seen in the fifth and sixth decades, whereas a polygonal or flattened structure was mainly observed after the seventh decade. CONCLUSION The histologic findings suggest that a decrease in the cellular components with advancing age may play a critical role in the development of degenerative changes.

Abstract
Postoperative complications of delayed osteosynthesis with stainless steel miniplates were examined in 110 patients with mandibular fractures. The miniplates were removed in 91 of the patients, even if symptom-free, once sufficient bony union was obtained, and the healing conditions and the surrounding tissues were examined. Malocclusion, exposure of miniplates, delayed union, and infection were observed in 3.6%, 3.6%, 1.8%, and 1.0% of the patients, respectively. The complication rates were within acceptable limits even when treatment was performed later than 24 hours after injury. The healing conditions and the surrounding tissues did not show any serious problems. Thus, at least in short-term retention, stainless steel miniplates seem to be effective and suitable for osteosynthesis of mandibular fractures.

Abstract
Eleven patients with oral and maxillofacial angiomas (seven hemangiomas and four lymphangiomas) were evaluated with magnetic resonance imaging using a 0.2-T permanent system and spin-echo pulse sequences. These lesions typically had signal intensities that were iso T1-weighted, similar to muscle, and high T2-weighted, greater than subcutaneous fat. Nine tumors had well- or relatively well-defined margins, and seven cases had curvilinear structures of low signal intensities in the masses on T2-weighted images. It was impossible to distinguish hemangiomas from lymphangiomas on MR images. Our experience suggested that most angiomas of oral and maxillofacial regions present special characteristics on magnetic resonance images. It is thought that information obtained with magnetic resonance images can contribute significantly to the evaluation of the extent of these lesions.

Abstract
Familial adenomatosis coli is known to be associated with tooth impactions, odontomas, and osteomas. Three cases were examined by panoramic radiography and computed tomography. Computed tomography was especially useful for detecting osteomas in the maxilla and also revealed a wavy cortical thickening in the mandible in one instance. The latter finding has been reported for other bones in the body but not previously for the mandible.

Abstract
Twenty-three patients suffering from familial adenomatosis coli (FAC) were followed for an average of 7 years (0.11-16.11 years). In 22 patients, jaw lesions including osteomas and/or odontomas were present at the first examination. In 12 patients, some changes occurred; that is, the number and size of the lesions increased. These findings indicate that changes of jaw lesions in FAC patients occur gradually even in adulthood.

Abstract
A 24-year-old male with pneumoparotis caused by the use of an air syringe during a routine restorative dental procedure during clinical training is presented. Reflux of air into the parotid gland due to increasing pressure is a rare cause of acute parotid swelling.--A discussion of this unusual case and review of the literature including its differential diagnosis and management form the basis of this report. Judicious use of intra-oral dental instruments using compressed air or gas is advised.

Abstract
A new method for quantitative occlusal measurement is presented. In this study occlusal contact areas in 79 patients with or without temporomandibular joint symptoms were assessed from the simple wax bite. The area of occlusion has showed no distinct differences between the two groups. The occlusal contacts did not show any significant correlations with temporomandibular joint dysfunctions.

Abstract
This article evaluates 16 cases of condylar fracture treated surgically, comparing them with the 20 cases treated nonsurgically, with a 2-year follow-up. Although severely displaced and luxated fractures were involved in the surgical group with rigid internal fixation, satisfactory postoperative function and occlusion were achieved at the same level as in the nonsurgical group, without severe complications.

Abstract
In spite of the small experiences, silicone capping with gap osteoarthroplasty in high level is thought to be one of the valuable procedures for TMJ ankylosis. In the view of kinesiology, a normal joint cannot be reconstructed, because the mandibular movement in ankylosis is far from the normals.

Abstract
Abnormalities of jaw bones and teeth were evaluated in 37 patients with familial adenomatosis coli (FAC) by means of orthopantomography. Osteomatous radiopaque lesions were evident in 75.7 percent of FAC patients (focal type: 62.2% and wide spread type: 13.5%), odontomes in 29.7% peripheral osteomas in 13.5%, unerupted teeth in 16.2% and supernumerary unerupted teeth in 16.2%. Five of the 37 FAC patients had an unusual widespread type of radiopacity with other abnormalities. Combined abnormalities were most frequent in patients with this type in comparison with patients with the focal type. Osteomas and peripheral osteomas were revealed in this type with statistical significance. Biopsy performed in one patient revealed an osteoma. These results suggest that the multiple abnormalities seen in oral X-ray examination may predict the occult existence of familial adenomatosis coli and these widespread radiopaque lesions probably represent the most extensive manifestation of FAC.

Abstract
There have been 20 patients treated by miniplate osteosynthesis following extraction of the lower third molar in fracture of the mandibular angle. It is possible that miniplates may almost completely replace conventional treatment. The result supports the efficacy of miniplates osteosynthesis for angular fracture of the mandible, in spite of the secondary operation for removal.

Abstract
Malformations of the extremities frequently accompany cleft lip and palate. An association of malformation of the extremities with transverse facial cleft, however, has never been reported. We have recently discovered a 5-month-old Japanese female with a transverse facial cleft accompanied by an accessory ear and hypoplasia of the upper extremity. The case is reported and a discussion is included.

Abstract
In this paper, the authors describe their surgical procedures, the clinical management, and radiological evaluation of condylar neck fractures. The condylar neck is the site of approximately two-thirds of all mandibular fractures. These are treated either conservatively or by open reduction. Indications for open reduction are discussed. Approximately 5-30% of all condylar neck fractures are treated surgically, depending on the circumstances of each case. The role of open reduction is realignment of segments, early function and decreased post-operative complaints. It has been our experience that surgical treatment of selected condylar neck fractures is successful.

Abstract
The discovery of insulin in 1922 aroused immediate clinical interest in its use in heart disease. In severe heart failure, insulin release is suppressed by the combined effect of poor pancreatic perfusion and by increased sympathetic activity. In these circumstances, myocardial metabolism of glucose may break down through the deficiency of insulin. Because of this, glucose, insulin and potassium solution (GIK solution) has been used in cardiopulmonary resuscitation. However, its mechanism is not yet fully known. This study was designed to determine the effect of insulin on cardiac muscle at various temperatures. The mechanical response of papillary muscle isolated from guinea pig ventricle was observed under various thermal conditions (23-37 degrees C). Twitch tension was increased by the administration of 0.2 I.U./ml insulin under each thermal condition. In all circumstances, the increase in contractile force was noted about 2 min after the administration of insulin. The effect of insulin on 20 preparations demonstrated the mean maximum contractile force was 226% ( +/- 34 S.D., n = 5) in 37 degrees C, 194% ( +/- 36 S.D., n = 5) in 30 degrees C, 190% ( +/- 30 S.D., n = 5) in 27 degrees C and 200% ( +/- 36 S.D., n = 5) in in 23 degrees C. The differences between different temperatures was not significant. The effect of insulin during depression Na-K pump by high concentration of ouabain (g-strophanthin, 10(-5) M) was also observed. Insulin (0.2 I.U./ml) was administered when the papillary muscle showed no response to electrical stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)
