Plerocercoid of Nybelinia surmenicola is found mainly in common squid. Plerocercoid of Nybelinia surmenicola is less recognized and has fewer clinical studies than Anisakis, which is highly pathogenic. However, understanding the clinical and histological features of plerocercoid of Nybelinia surmenicola is extremely important for differential diagnosis. We describe a case of plerocercoid of Nybelinia surmenicola invasion that occurred in the oral mucosa with clinical photographs and histopathological findings. The patient was a 65-year-old woman who presented with foreign bodies of the tongue and buccal mucosa with pain. Biopsy of the foreign bodies was performed to confirm the diagnosis. Symptoms improved after 1 week without active treatment except for antibiotic administration. At the same time, the search results for plerocercoid of Nybelinia surmenicola obtained from commercial squid were added to the findings of this study.

The most effective treatment for adenoid cystic carcinomas arising from minor salivary glands is surgical removal of primary lesion including the wide safety margin. However, it is well known that the salivary gland tumors have poor prognosis and high frequency of metastasis. Therefore, the multidisciplinary therapy that prevents effectively recurrence and metastasis is needed.<BR>Two cases of adenoid cystic carcinoma of the maxillary sinus were treated according to the follwing multidisciplinary method. Case 1 (T3NOMO by JJC proposal): The patient had surgical removal of the affected maxilla and then radiation therapy. Four weeks later, adjuvant chemotherapy (Adriamycin and Cisplatin) was performed. In addition, UFT and OK-432 were administered continuously up to date from the onset of the treatment. Consequently, the patient remains be disease-free 24 months postoperation. Case 2 (T4NOMO by JJC proposeal): The patient was treated with the multidisciplinary methods such as surgical reduction of a tumor-burden, radiation therapy, intraarterial infusion of cisplatin and 5-FU into a superficial temporal artery and intradermal administration of OK-432. Thereafter, complete regression of the primary tumor was observed. However, metastasis was detected in the regional lymph nodes, which were subjected to radical neck dissection. The patient remains be disease free 8 months postoperation. These findings indicate that the multidisciplinary therapy may improve the prognosis of adenoid cystic carcinoma of the maxillary sinus.

Polycythemia vera (PV) is one of myeloproliferative neoplasms characterized by a remarkable increase in myeloid cells caused by abnormality of the hematopoietic stem cells. In patients who receive surgical treatment for PV, conflicting complications such as thrombosis and hemorrhage develop frequently. We report a case of PV diagnosed after postextraction hemorrhage. A 75-year-old woman was found to have polycythemia on a health checkup two years previously, but did not receive any treatment for it. She had her left maxillary wisdom tooth extracted at a dental clinic, but was referred to our hospital immediately to manage postextraction hemorrhage. We performed hemostatic treatment with the patient under local anesthesia. Because of the severe hemorrhage, blood examinations were performed and showed increased counts of white blood cells, red blood cells, and platelets. Therefore, we consulted a hematologist, and she received additional examinations. JAK2 gene mutation was positive, bcr/abl t (9;22) translocation was negative, and decreased erythropoietin was revealed. From these results, she was given a diagnosis of PV according to the WHO diagnostic criteria in 2016. Now, six months after tooth extraction, she is being treated by regular phlebotomy, daily oral aspirin, and hydroxyurea to control the blood cells.

Acquired hemophilia A is a very rare disease caused by the acquisition of factor Vlll inhibitor. We report a case of acquired hemophilia A incidentally diagnosed in a patient who had bleeding after tooth extraction. A 77-year-old man who complained of bleeding after tooth extraction presented at our hospital. Hematological examination revealed a prolonged activated partial thromboplastin time (APTT), decreased coagulation activity of factor Vlll, and high level of factor Vlll inhibitor. Consequently, acquired hemophilia A was diagnosed. The patient received corticosteroids and bypass therapy. Four months later, the APTT and factor Vlll activity returned to the normal level. Although this is a very rare case, we should suspect hematologic disease, including acquired hemophilia A, when we encounter patients with bleeding after tooth extraction.

The prevalence of syphilis has increased in Japan since 2010. Its rapid increase among women in their 20s is of particular concern because it is associated with an increase in the prevalence of congenital syphilis. We report a case of primary syphilis diagnosed from a tongue ulcer in a pregnant woman who did not receive antenatal care. A 29-year-old pregnant woman, who did not receive antenatal care, presented with a tongue ulcer at our hospital. She had a history of being a commercial sex worker. Laboratory tests revealed elevated C-reactive protein levels (5.56 mg/dL) and positive TPLA and RPR. We referred the patient to the department of infectious diseases as well as to the department of obstetrics and gynecology. She was treated with benzylpenicillin potassium (24 MU/day) for 14 days. Later, the tongue ulcer disappeared and RPR showed negative results. She gave birth to a boy who did not have congenital syphilis. The number of patients with syphilis presenting with oral symptoms is increasing, and it is expected that more of such cases will be examined by dentists. Therefore, it is crucial to consider syphilis as a differential diagnosis of oral mucosal disease and establish coordination among specialists who can be consulted and referred to when syphilis is initially suspected.

We report a case of extensive bisphosphonate-related osteonecrosis of the jaw (BRONJ) associated with a mandibular fracture, which improved after treatment with teriparatide and surgical therapy. An 83-year-old woman was referred to our hospital because of swelling of the submandibular region. At presentation, clinical examination revealed swelling of the right submandibular region and discharge of pus. A computed tomographic (CT) scan confirmed osteolytic changes and a fracture of the mandible. Three months after bone curettage, fixation with a titanic plate, and treatment with teriparatide, new bone formation was observed. Five months after this therapy, the fractured segment had completely healed. Teriparatide may contribute to the improvement of BRONJ.

Nineteen cases of unilateral cleft lip and nose were measured and evaluated before and after open rhinoplasty with the use of facial plaster models and a high-accuracy threedimensional digitizer (TRISTATION400CNC, Nikon, Tokyo). Surgery was performed from 1990 through 1994. The mean age of the subjects was 18.6 years.<BR>Three-dimensional wire-frame models were obtained from facial plaster models, and nasal landmarks were extracted automatically by an original program. The landmarks were evaluated and compared according to three operation techniques:(1) Flying bird group: A flying bird incision was made across the columella, and a tornado incision was made in the nostril. After cartilage reconstruction, complex tissue was transplanted into the nostril. Furthermore, Z-plasty was done across the white lip and the alar base of the affected side.(2) Col. base-graft group: An incision was made in the columella base and nostril rim. After cartilage reconstruction, ear cartilage was transplanted onto the nasal tip, alar, or both (3) Col. base-non-graft group: An incision was made in the columella base and nostril rim. The nasal cartilage was reconstructed without a graft.<BR>The nasal tips deviated about 5 mm to the normal side before operation and were corrected after operation in all groups. In the flying bird and col. base-graft groups, the nasal tips moved about 3 mm anteriorly. The difference in the distance between the columelia base and the alar base decreased markedly in the flying bird group. The columella base deviated about 3mm to the normal side before surgery and was corrected after surgery in all groups. In the Col. base-graft group, the columella base protruded inferiorly after operation. No remarkable change was observed in the alar dip in any group.<BR>The procedure used in the flying bird group was suggested to result in a better morphological outcome than the procedures used in the col. base with/without graft groups.

Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) is a recently recognized B-cell lymphoproliferative disorder that is driven by latent EBV infection and causes discrete ulcerations in the oropharynx, gastrointestinal tract, and skin. A 56-year-old Japanese woman with a 1-month history of swelling in the right side of lower gingiva visited our hospital. The patient had a past medical history of rheumatoid arthritis (RA). She had been given a diagnosis of RA in 1981 and had received standard treatment with methotrexate (MTX) (8 mg/week) for more than 26 years (total dose, greater than 3840 mg). Following initial biopsy and withdrawal of the MTX, the area healed spontaneously over a period of several weeks. The morphological and immunophenotype features were in keeping with an EBV-related lymphoproliferative lesion consistent with EBVMCU. We requested discontinuation of methotrexate, and the lesion decreased and symptoms disappeared in 2 months. There was no evidence of recurrence 25 months after discontinuing methotrexate.

Low-grade central osteosarcoma, a rare subtype of osteosarcoma, is less aggressive than conventional osteosarcoma. We report ac case of low-grade central osteosarcoma of the mandible. A 52-year-old woman presented to our department for treatment of a swelling in the right side of the mandible. Computed tomography revealed ground glass radiopaque lesions associated with an expansive growth pattern in the mandibular bone. Because a suspicion of low-grade central osteosarcoma was diagnosed In the biopsy sample provided from the previous hospital, the lesion was surgically resected. Histopathologically, the tumor consisted of a dense proliferation of spindle cells with mild atypia. At the periphery of the lesion, the normal cortical bone was invaded by tumor nests. Low-grade central osteosarcoma was diagnosed in the surgical specimen. Tumor recurrence has not been observed for more than 6 years after surgery. Low-grade central osteosarcoma is hard to differentiate from osteogenic benign neoplasm or bone malformation. Therefore, when radiographic findings reveal an expansive ground glass appearance, a bone biopsy including the normal cortical bone and the central part of the lesion is essential.

Fall in child is relative more as a course of injuries on tooth, gingiva, alveolar bone, lip, tongue and buccal mucosa in house. In adult, fall on walking, hits in sports and working accidents are most courses. Injuries of oral and maxillofacial region should be repaired correctively on short times to be anatomical tissue situation just before accident. It is good points to preserve the dislocated tooth as far as possible, to repair the bone fragments and to suture the muscle and epithelium correctively. Drainage is necessary on infected wounds. It needs to observe the color of tooth crown, absorption of tooth root-apex. We have to observe the development of mandible on child. Treatment of trigeminal and facial nerve injuries are usually dosage corticosteroids and vitamin B12.

It is beneficial for postdoctoral Japanese oral and maxillofacial surgery (OMFS) training to evaluate postdoctoral OMFS programs in other developed countries. Such studies should contribute to improving the quality of oral health in Japan. Currently there have been no research articles introduced for Japanese oral and maxillofacial surgeons that report on the postdoctoral OMFS training programs in the United States of America (USA). We therefore report the current status of oral and maxillofacial surgery training programs in the USA.Eleven topics are discussed. OMFS residency programs in the USA are speciality programs designed for oral and maxillofacial surgeons. Certification by the American Board of Oral and Maxillofacial Surgery is achieved after 4 to 6 years of training. A medical school curriculum is included in 46 of 102 OMFS residency programs. The average duration of the medical school curriculum was 28.4 months. Such curricula are designed to train OMFS residents who possess standard knowledge and techniques. The programs are strictly managed by a program director.

Congenital maxillomandibular fusion is a very rare congenital anomaly in which the maxilla (medial orbital wall or maxillary process) and mandible (mandibular process or lateral lingual swelling) adhere via bony or soft tissue. It is also called congenital maxillomandibular fusion or congenital syngnathia or congenital oral synechia, but is referred to as congenital maxillomandibular fusion in this paper. We describe a case that developed in a 2-day-old male infant with cleft lip and palate. He was born at 40 weeks, 4 days’ gestation and weighed 3046 g. The Apgar score was 8/9. His condition was diagnosed as lactation disorder, cleft lip and palate, and a funicular structure from the lower lip to palate at birth, and he was admitted to our department in Okinawa Chubu Hospital. We resected the funicular structure extending anteriorly from the left lower lip to the left incisive bone. To date, five kinds of desmoplastic attachment areas have been reported, which are the residual ridge interval, floor of mouth and hard palate, tongue and hard palate, tongue and soft palate, and lower lip and the hard palate. Cleft palate is the most commonly reported complication of congenital maxillomandibular fusion, and syndromes such as Van der Woude syndrome (cleft lip and palate, lower lip fistula), popliteal pterygium syndrome (cleft lip and palate, lower lip fistula, genital malformation, limb malformation, popliteal pterygium) have also been reported. Only two cases of congenital maxillomandibular fusion in which the palate adhered to the lower lip in association with popliteal pterygium syndrome have been reported. We recently encountered a patient with bilateral cleft lip and palate who had adhesion between the lower lip and hard palate, and report this case along with a review of the literature.

Traumatic carotid-cavernous sinus fistula (t-CCF) is an arteriovenous fistula formed by the tearing of the internal carotid artery running in the cavernous sinus, accompanied by head/maxillofacial injuries. Patients with this disease rarely show spontaneous closure and often require urgent endovascular treatment. We report a case of t-CCF that developed following jaw and zygoma fractures and was successfully treated by manual carotid compression. A 35-year-old man was referred to our hospital to undergo treatment for multiple maxillofacial fractures. On the first day after injury, open reduction and internal fixation of the mandible were conducted with the patient under general anesthesia. On the fifth day after injury, diplopia of the left eye suddenly appeared. On the seventh day after injury, left exophthalmos/edema of the left upper eyelid/left abducens nerve palsy/bilateral ptosis, and hyperemia of the bulbar conjunctiva appeared. On the 15th day after injury, cerebral angiography revealed a definitive diagnosis of t-CCF. Supervised manual carotid compression during the waiting period before endovascular treatment led to improvement in various symptoms from the 19th day after injury. Cerebral angiography, which was performed again for endovascular treatment, revealed that arteriovenous fistula resolved spontaneously. Therefore, treatment was discontinued, and the patient was followed up with a conservative approach. By 9 months after injury, all symptoms, including left oculomotor nerve palsy had disappeared. There was no evidence of recurrence 10 years after injury.

Guideline to prevent surgical site infection was published from Japanese society of surgical site infection and Japanese society of antibiotics chemotherapy in 2016. In the guideline, antibiotics prophylactic regimen has described in the all field of surgeries including oral surgery and dentistry. In 2018, Japanese society of cardiology published revised version of ‘Prevention and treatment of infective endocarditis (IE)’. In the guideline, antibiotics prophylaxis of IE in dentistry has described extensively. Since proper use of antibiotics for prevention of antimicrobial resistant bacteria production in oral surgeries has not been discussed sufficiently, we oral surgeons should understand the importance of proper antibiotics prophylaxis in oral surgery in accordance with these new guidelines.

We report a case of pyostomatitis vegetans associated with ulcerative colitis. The patient was a 25-year-old woman referred to our hospital because of irritative pain of the right side of the buccal mucosa. She had been receiving mesalazine for ulcerative colitis for 4 years. An erosion with a cobblestone appearance and a small ulcer were observed on the right side of the buccal mucosa. Histopathological examination showed subepithelial microabscesses containing lymphocytes and eosinophils in the subepithelial connective tissue. We finally diagnosed pyostomatitis vegetans associated with ulcerative colitis. The oral lesion completely disappeared 1 month after the administration of prednisolone.

<p>Clear cell odontogenic carcinoma (CCOC) was reclassified from a benign tumor to a malignant tumor by the WHO classification in 2005 because of its aggressive nature and potential for local recurrence and distant metastases. Only 81 well-documented cases have been reported to date to the best of our knowledge. A patient was referred to our clinic because of rapid swelling of the left side of the mandible. Computed tomography (CT) showed a bone defect in the mandible, but no cervical lymph node metastasis. We suspected a malignant tumor and performed a biopsy. We diagnosed CCOC of the left side of the mandible and performed segmental mandibulotomy. Histopathologically, the tumor consisted of clear cells containing diastase-digestive PAS-positive granules. Furthermore, immunohistochemistry showed that the tumor cells were immunoreactive for cytokeratins (CKs) 7, 17, 19, Ki-67 and vimentin, but non-reactive for CK20, smooth muscle actin (SMA), epithelial membrane antigen (EMA) and S-100 protein. The Ki-67 labeling index (LI) was 10%. We finally diagnosed CCOC. One year 5 months after surgery, the patient died of multiple organ failure caused by the multiple bone metastases. We discuss this rare case of multiple bone metastases developing from CCOC of the mandible and review the literature.</p>

Amyotrophic lateral sclerosis (ALS) is an incurable, progressive, and neurodegenerative disease specifically affecting both upper and lower motor neurons. It induces dysphagia, reduction of respiratory function, and limb muscle weakness, leading to aspiration pneumonia and respiratory insufficiency. ALS can be detected at dental visits on the basis of early oral symptoms such as dysphagia. However, there are few reports describing ALS in dental journals. We describe a man aged 59 years who visited our department because of functional changes, including decreased swallowing ability. Imaging studies demonstrated no tumor lesions, but tongue fasciculations were present. Videofluorographic evaluation revealed incorrect swallowing (aspiration) and food remaining in the larynx. We consulted the department of neurology in our university hospital. Because needle electromyography and other examinations ruled out other possible diseases, the patient was given a diagnosis of ALS. We made a palatal augmentation prosthesis to maintain deglutition function and followed up oral function. Oral symptoms of ALS are sometimes observed in its early stage. Therefore, oral surgeons and dentists need to possess adequate knowledge about this disease.

Recently, the occurrence of methotrexate-associated lymphoproliferative disorders (MTX-LPD) in the oral area is reported one after another. We report a case of MTX-LPD of the maxillary gingiva associated with rheumatoid arthritis (RA). A 80-year-old man was referred to our clinic because of severe pain associated with a ulcer on the left side of the maxillary gingiva. On blood tests, soluble interleukin-2 receptor (sIL-2R) was high, and EBV infection was detected. The histopathological diagnosis was EBV-positive diffuse large B cell lymphoma (DLBCL). He had been receiving methotrexate for RA. We therefore requested discontinuation of methotrexate, and the lesion was decreased and symptoms disappeared. Examination after 21 months showed no evidence of recurrence.We reviewed reports documenting 17 cases of oral MTX-LPD in Japan. The age of onset was 40-84 years old, the male-to-female ratio was 4:13, and the methotrexate treatment period was 1-114 months. The affected sites were the maxillary and mandibular gingiva in 14 cases, the tongue in 1 case, and the mouth floor in 1 case. On histopathological classification, 14 cases were non-Hodgkin’s lymphoma, and 1 case was Hodgkin's lymphoma. As for the course of treatment, 11 cases had remission with cessation of methotrexate. Symptoms improved in 1-2 weeks, and lesions disappeared in 1-4 months.

We report a case of chronic expanding hematoma (CEH) in the temporomandibular joint (TMJ) region. A 48-year-old man visited our department because of a mass in the left preauricular region and trismus in November 2012. He had noticed the mass about 2 months previously, which gradually expanded. At initial presentation, examination revealed a hard elastic mass, measuring 22 mm in diameter, in the left preauricular region. The maximum mouth opening was 33 mm. Computed tomography showed a well-demarcated mass lateral to the mandibular condyle, accompanied by condylar bone resorption. On magnetic resonance imaging, the mass showed heterogeneous high signal intensity on T1-weighted images and heterogeneous low signal intensity on T2-weighted images. The mass showed mild uptake on 2-deoxy-2- [18F] fluoro-D-glucose positron emission tomography. Fine needle aspiration yielded a diagnosis of class I. The clinical diagnosis was a suspected tumor in the left TMJ region. The lesion was extirpated with the patient under general anesthesia in December 2012 and was histopathologically diagnosed as hematoma. On the basis of the clinical course and histopathological findings, the lesion was finally diagnosed as CEH. As of about 3 years after surgery, the postoperative course has been uneventful, with no evidence of recurrence.

Lemierre syndrome is a potentially life-threatening disease caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein, frequently associated with abscess formation in distant organs.We report the case of a 78-year-old woman who received surgical therapy, chemotherapy, and radiation therapy for malignant lymphoma in 2001. She visited our hospital because of a swelling and pain of the left submandibular region in August 2009. The patient was immediately hospitalized to control the pain and infection. PET images showed tracer uptake in the lung. Bilateral multiple septic emboli of the thorax were detected on CT. On the basis of these findings, Lemierre syndrome was diagnosed. The patient was treated with antibiotics intravenously, and surgical drainage was performed. All symptoms improved, and she was discharged after 32 days.
