Abstract:

Carbamazepine is widely used as an anticonvulsant or antipsychotic agent. As a sodium channel blocker, it provides therapeutic benefit in patients with trigeminal neuralgia and may be used for the differential diagnosis of pain. We report a case of marked thrombocytopenia during carbamazepine administration in a patient with idiopathic trigeminal neuralgia. A 37-year-old woman presented with acute intermittent electric shock-like pain when pressure was applied to the left mental foramen, or when cold air was applied to the left lower lip. We observed no sign of dental infection. No obvious vascular contact in intracranial lesions or the trigeminal nerve root entry area was observed in MR imaging. We initiated carbamazepine (200 mg/day) therapy for a clinical diagnosis of idiopathic left trigeminal neuralgia (tertiary branch). The patient developed petechial hemorrhages on the face, neck, and extremities 16 days after carbamazepine administration, and blood test results revealed significant thrombocytopenia (her platelet count was remarkably low, at 1.5×104 /μ L). We suspected carbamazepine-induced thrombocytopenia. The medication was discontinued, resulting in a gradual disappearance of the petechial hemorrhages and recovery of the platelet count to 23.7×104 /μ L six days after carbamazepine cessation. Subsequently the left-sided mental foramen pain was controlled with pregabalin administration (150 mg/day), without any adverse effects.

Abstract:

Fanconi anemia is an inherited genetic disorder characterized by progressive pancytopenia, transition to myelodysplastic syndrome, acute myeloid leukemia, body malformation, and increased risk of certain solid cancers. Among the solid tumors, there is a high incidence of squamous cell carcinoma of the head and neck. Here, we report a case of advanced lower gingival cancer in a patient with Fanconi anemia.

 A 30-year-old man was referred to our hospital because he was aware of a painless mass arising in the right mandibular gingiva. In his medical history, the patient was given a diagnosis of Fanconi anemia at the age of 6 years because of pancytopenia. The patient achieved hematological recovery after allogenic hematopoietic stem cell transplantation following a preparative regimen consisting of total body irradiation and cyclophosphamide. The right mandibular tumor (36×27 mm) was diagnosed as lower gingival cancer. The patient underwent bilateral neck dissection, segmental mandibular resection, and total resection of the lower lip (squamous cell carcinoma, pT4aN2cM0). Reconstructive surgery comprised placement of a reconstructive titanium plate, a pectoralis major musculocutaneous flap, and local rotational flaps.

 Postoperative adjuvant treatment was not administered. 30 months postoperatively, there was no new lesion, recurrence, or metastasis.

Abstract:

Leiomyomatous hamartoma mainly occurs in the liver, spleen, kidney and lung. It is rarely found in the oral region.

 We report a case of leiomyomatous hamartoma arising in the hard palate of a 6-month-old female infant. Six months after her birth, her parents consulted the obstetrician about a tumor of the hard plate and were referred to our department. Although it had been recognized since her birth, she could suck milk without any problems. The results of medical examination revealed that there was no problem in general condition. The tumor was an elastic soft, and cord-like mass that measured about 15 × 3 mm and was localized in the incisive papilla. The primary clinical diagnosis was a benign tumor of the hard palate. An excisional biopsy was carried out in the outpatient clinic by using local anesthesia. Immunohistochemical analysis showed positive reactions for α-smooth muscle actin (α- SMA) and HHF35, which showed the growth of smooth muscle. A histological diagnosis of leiomyomatous hamartoma was established. Postoperative observation has revealed no recurrence as of 13 years after the operation.

Abstract:2005年1月から2013年12月までの9年間に旭川医科大学病院歯科口腔外科を時間外に救急受診した患者を対象に臨床的検討を行った。対象期間中の休日および時間外患者総数は1,002名で性別は男性が551名、女性が451名であった。年齢分布は0歳から99歳で、30歳未満が全体の約半数を占め、それ以降は加齢に伴い患者数が減少していた。月別患者数は12月に100名(9.98%)と最も多く、2月は44名(4.4%)と最も少なかった。疾患別では炎症が371名(37.0%)と最も多く、次いで外傷328名(32.7%)であった。救急車で搬送された患者が57名(5.69%)、受診後に入院となった患者は38名(3.79%)であった。旭川医科大学病院では救命救急センターが稼働したことでさらに炎症や外傷が多くなると予想された。今後歯科口腔外科は専門科としての役割が大きくなり、一般歯科治療のために時間外救急受診する症例への対応が課題になると思われる。

Abstract:S-1 chemotherapy is widely used to treat head and neck cancer. Reports of interstitial pneumonia as a side effect of S-1 chemotherapy are very rare.
We report a case of interstitial pneumonia possibly caused by S-1 treatment as postoperative adjuvant chemotherapy.
We gave S-1 as postoperative adjuvant chemotherapy for mandibular gingival carcinoma in a 80-year-old woman. She had a fever 53 days after starting S-1 chemotherapy. The X-ray films and computed tomography (CT) showed reticular shadows in both lung fields, and the patient was given a diagnosis of interstitial pneumonia. The results of a drug-induced lymphocyte stimulation test were positive against S-1. The total dose of S-1 until the onset of symptoms was 3360 mg. We immediately started steroid therapy and withdrew S-1 chemotherapy, and then the symptoms remarkably improved, as did the abnormal findings on CT.
In conclusion, when a patient has a high fever and dyspnea during S-1 therapy, drug-induced interstitial pneumonia should be included in the differential diagnosis.

Abstract:We devised a treatment protocol for simple tooth extraction that conforms to the "Guidelines for management of anticoagulant and antiplatelet therapy in cardiovascular disease (JCS2004)". Using this protocol, 1,020 simple dental extractions were performed in patients on antithrombotic therapy (patient group) and in control patients (control group).
We statistically analyzed bleeding after tooth extraction following complete hemostasis (postoperative bleeding), difficulty stopping bleeding after tooth extraction (hemostatic difficulty), background factors, contents of hemostasis, antithrombotic medications, oral surgery specialist qualification of the operator, and PT-INR.In the patient group, 56 cases with hemostatic difficulty were observed (14.7%) and postoperative bleeding (3.1%) after extraction occurred in 12 of the 382 cases. In the control group, there were 12 cases with hemostatic difficulty (1.9%) and one with postoperative bleeding (0.2%) among the 638 undergoing extraction. Hemostatic difficulty and postoperative bleeding requiring serious systemic hemostatic intervention was not observed in any of the cases undergoing extraction. Factors related to hemostasis difficulties were local inflammatory and anti-platelet therapy and warfarin therapy. Factors associated with postoperative bleeding were oral surgery specialist qualification and warfarin therapy.
In this study, tooth extraction was performed employing our protocol which is based on compressive hemostasis. Tooth extraction can be safely carried out during antithrombotic therapy with appropriate local hemostasis. Furthermore, hemostasis was possible with a local hemostatic method in all cases of the patient group and the control group.

Abstract:This report presents a case of chronic mandibular dislocation treated by conservative reduction in a patient who was receiving anticoagulant therapy. The patient was a 65-year-old woman who was referred to the Department of Oral and Maxillofacial Surgery in Asahikawa Medical University for the treatment of chronic mandibular dislocation. Chronic mandibular dislocation had developed during hospitalization for cardiogenic embolism. Since the patients physician recommended us to continue anticoagulation therapy, we decided to perform conservative reduction by lever action, using intraoral blocks with built-up heels and elastic traction. Because the patient was edentulous, we innovated on past reports of conservative reduction by lever action using teeth. Eleven days after treatment, the reduction was successful, and the jaws were stable. By 1 year after treatment, there was no recurrent dislocation, and the outcome was good.

Abstract:Essential thrombocythemia (ET) is a rare chronic myeloproliferative tumor characterized by an increase in platelets, thrombosis, and a bleeding tendency. Special attention is reguired in cases treated by surgical intervention. We describe the resection of tongue cancer in a patient with ET. A 79-year-old man was admitted to our hospital because of discomfort in the left margin of the tongue. Initial examination revealed an 18 × 11 mm indulated mass arising at the left tongue margin. The clinical diagnosis was suspected tongue cancer. ET had been diagnosed at 66 years of age, and hydroxycarbamide was administered. The preoperative platelet count was 73.4 × 104/μl. Preoperatively, we continued to administer hydroxycarbamide after consulting with the attending physician. We performed an excisional biopsy. The operation was completed without any major problems. Half a day after the operation, diapedetic bleeding occurred. We therefore performed local hemostatic treatment with resuturing. The platelet count increased to 103.5 × 104/μl by the next day. To prevent thrombosis and bleeding, we administered the alkylating agent ranimusstin. Three days later, the platelet count decreased to 63.4 × 104/μl. The postoperative course has been uneventful without bleeding or an increased platelet count. There has been no tumor recurrence for more than 7 years.

Abstract:著者最終原稿版42歳女。インプラント埋入術を施行し、上部構造を装着した。インプラント周囲歯肉の腫脹を認めた。インプラント周囲炎の診断下に歯肉剥離掻爬術を施行され、創部保護を目的にユージノール性歯周包帯を貼付された。術後2日目より同部周囲組織の浮腫性腫脹を自覚した。その後口腔内の腫脹、口腔粘膜の接触痛および嚥下痛による摂食障害を生じた。ユージノール性歯周包帯が原因のアレルギーを疑い、口腔内に飛散しないように慎重にこれを除去した。また、舌の白苔に対し口腔カンジタ症も念頭に置き、細菌培養検査を施行した。口腔内の発赤、腫脹、疼痛の原因として、ユージノール性歯周包帯による遅延型アレルギー反応が考えられた。口腔内外の症状はユージノール性歯周包帯除去後から消退した。ユージノール性歯周包帯除去後6日目、局所状態が改善し、それに伴い経口摂取も問題なくできるようになったため退院した。

Abstract:We report a case of contact stomatitis due to a periodontal dressing material (surgical pack N®). In July 2007, a 42-year-old woman presented at our hospital complaining of pain in the mouth. The patient had severe pain due to stomatitis around the upper right gingiva and buccal mucosal membrane in contact with a periodontal dressing material which had been placed for wound protection after a flap operation for peri-inplantitis at a dental clinic. An allergic reaction was suspected in the region surrounding the periodontal dressing material. The patient underwent a patch test for some dental metals, periodontal dressing materials and liquid inside periodontal dressing materials. As a result, the liquid of a periodontal dressing material was indicated as the source of the stomatitis. After removing the periodontal dressing material, the stomatitis and symptoms disappeared.

Abstract:Oral myxoma usually arises in the jawbone and rarely occurs in soft tissue. A case of myxoma in the gingiva of the upper jaw is reported. The patient was a 75-year-old man, who had noticed a tumor in the right molar gingiva 40 years ago. The tumor became larger after extraction of an upper molar. A mushroom-shaped elastic hard tumor (20 × 20 × 15 mm) was noted in the upper molar gingiva. Radiographic and computed tomographic examinations showed a tumor in the maxilla, but extensive bone resorption was not observed. An incisional biopsy was done, and the diagnosis was myxoma. Partial maxillectomy including the tumor was performed with the patient under general anesthesia. Histopathological examination showed that the tumor was composed of spindle-shaped cells in a myxoid matrix. The tumor was situated mainly in the gingiva, but slight pressure-related bone resorption was observed on the surface of the alveolar bone. Four years after treatment, there was no evidence of recurrence.

Abstract:We describe our experience with 4 patients who had squamous cell carcinoma of the soft palate treated by superselective intra-arterial chemoradiotherapy. Two patients had stage Ⅱ disease, and 2 had stage Ⅳ disease. Two of them presented regional lymph node metastatsis. All patients received cisplatin alone. The mean total dose of cisplatin was 461.3mg (300-600mg). Cisplatin was injected into the facial artery or the ascending palatal artery through the superficial temporal artery, with 200 mol times of sodium thiosulfate as the cisplatin neutralizer.
All patients received radiotherapy in a dose of 66 Gy and had a complete response. The primary tumor recurred in 1 patient, but was successfully resected by salvage surgery. All patients were alive at an average follow-up of 58.6 months.

Abstract:  We performed a clinical analysis of 145 children younger than 15 years who had oral and maxillofacial traumatic injuries treated at the Department of Oral and Maxillofacial Surgery, Asahikawa Medical University during the past 5 years (April 2004 to March 2009). The following conclusions were made:
  The ratio of male to female patients was 1.8:1. As for the age distribution, 1-year-old children had the highest incidence of injuries. Analysis of the monthly frequency of injuries showed that September was highest month, and February was the lowest month. Forty percent of the patients visited our hospital on a Saturday, Sunday, or national holiday. The highest proportion of injuries occurred between 15:00 and 18:00. About 87% of the patients visited our hospital directly, and 88.2% of the patients visited our hospital on the day of injury. The causes of injury were falls and drops (66.2%), traffic accidents (8.9%), and sports (7.5%). The most common site of soft tissue injury was the lip, and the most common site of tooth injury was the maxillary anterior primary teeth. Half of the patients were observed without any surgical treatment.

Abstract:1988年から2007年12月までに遊離肩甲骨皮弁を用いた一次再建例中,1年以上の経過観察が可能であった47例を対象として,再建後の咬合状態,食事の摂取について検討した。下顎の欠損はUrken分類を用いた。B,BSの狭い範囲の欠損では歯牙残存率が高く,顎義歯の装着なしでも常食摂取症例は多数であった。欠損範囲の拡大に伴い残存歯は少数となり,無歯顎となる割合は高率となった。そのため, 常食摂取率は欠損範囲の拡大に従って低下する傾向が認められた。特にRBSSB,BSSBの広範囲な欠損症例では,歯槽部がほとんど欠損するため,義歯床下は皮弁となり,義歯の維持は困難であるが,再建骨へのインプラント植立により義歯の維持は向上した。また,無歯顎であっても,再建骨の形態が良好でskin paddleが菲薄であればインプラントなしでも義歯の維持は良好となり,常食の摂取は可能であった。良好な顎口腔形態の再建が顎口腔機能の回復には重要であると考えられた。
