Angioedema is sudden local swelling of the lips, eyelids, buccal region and tongue. It is usually induced by drugs. Angioedema is a well-recognized side effect of angiotensin-converting enzyme inhibitors (ACEs), but angioedema associated angiotensin II receptors blockers (ARBs) is very rare. We report a case of angioedema of the tongue and floor of the mouth that was probably induced by an ARB.A 76-year-old man came to our emergency unit because of acute swelling of the tongue and difficulty breathing.He had a medical history of hypertension and cerebral infarction, but no allergic disease. He had severe diffuse edematous swelling of the submandibular and cervical regions, an elevated tongue making it difficult to close his mouth, and sialorrhea.Although urgent computed tomography showed marked swelling of the tongue, there was no evidence of edema in the respiratory tract. Angioedema of the tongue was diagnosed, and hydrocortisone sodium succinate was given intravenously. Within 12 hours the swelling of the tongue and floor of the mouth resolved completely.Candesartan was strongly suspected to have caused the angioedema, and we discontinued it. There has been no evidence of recurrence of the angioedema during the 18 months since candesartan was discontinued.

To assess the malignant potential of tongue cancer by intraoral ultrasonography, we examined 22 patients with squamous cell carcinoma of the tongue. Ultrasongraphic findings of the lesions were evaluated with respect to shape, border, internal echo, marginal echo, and depth of invasion (usD). Except for 3 tumors with a pathologic depth of invasion (pD) of less than 1 mm, 19 of 22 tumors (86.4%) were detected as hypoechoic lesions on intraoral ultrasonography. When the ultrasonographic and clinicopathologic findings were compared, tumors with diffuse invasion exhibited irregular shapes and diffuse borders on ultrasonography. Tumors with neck metastasis showed irregular shapes, diffuse borders, and hyperechoic marginal echoes. In addition, there was a significant correlation between usD and pD. Seven (58.3%) of 12 tumors with invasion of 8.0mm or more on ultrasonography were associated with neck metastasis.In conclusion, intraoral ultrasonographic examination of tongue cancer provides information useful in evaluating tumor extent and malignant potential.

Children often play with foreign objects such as a toothbrush in their mouths and sustain intraoral lacerations. Rarely, the objects penetrate into the parapharyngeal space and have to be surgically removed in cooperation with other specialties. We report a case of an intraoral penetration injury caused by a toothbrush entering the parapharyngeal space. A 2-year-old girl who was brushing her teeth before bedtime was intraorally impaled with a toothbrush after falling from an indoor jungle gym for infants. The patient was transferred to the emergency room in our hospital. CT scanning showed the toothbrush head near the internal carotid artery in the parapharyngeal space. Antibiotics were intravenously administered, and the foreign body was removed under general anesthesia, followed by wound suturing. The patient was discharged on the 7 day without any complications such as post-traumatic thrombosis of the internal carotid artery or deep neck abscess. It is important to adequately educate parents and their children about the dangers of a toothbrush as a foreign body that can cause serious penetration injuries.

We studied soft tissue injuries of the oral cavity caused by a toothbrush in 59 children younger than 7 years from 1983 through 2003. There were 35 boys and 24 girls aged 9 months to 6 years 7 months, with a peak incidence at 1 year. Falling down was the cause of injuries in 46 children. Forty-one children visited us directly, whereas others were referred to us by surgeons, emergency specialists, dentists, otolaryngologists, and others. Thirty-one children presented within 3 hours after injury and 15 the following day. The soft palate and palatoglossal arch, buccal mucosa, hard palate, oral floor, retromolar region, upper lip, gingiva, and tongue were involved in 25, 20, 6, 3, 2, 1, 1 and 1 child, respectively. Lacerations greater and less than 10 mm long were seen in 20 and 16 hildren, respectively. Submucous bleeding was present in 13 children, and scratches were present in 10 children. In 3 children, the wound was associated with herniation of the buccal fat pad. The wound was sutured and antibiotics were given to 23 children. Twenty children were observed without antibiotic treatment, and 16 children were given antibiotics. Local infection occurred in 3 children.

We examined 13 cases of primary oral aspergillosis in adult leukemia patients.Although the patients received systemic and local antifungal treatment in laminar air-flow rooms, primary oral aspergillosis generally developed in about 20 days in association with adrop in leukocyte count to under 1, 000/mm3 after chemotherapy. The initially involved area was the marginal gingiva which was associated with necrosis and severe pain. At the same time, spiking fever of about 39°C was observed. Necrotic changes of the gingiva progressed rapidly and invasively extended from the mucosa to muscle and bone. Local aspergillosis basically disappeared when the hematologic status of the patients returned to normal levels under antifungal treatment. The prognosis of primary oral aspergillosis was relatively good. However, damaged oral tissues were easily reinfected with aspergillus during chemotherapy.These findings suggest that oral hygiene plays an important role in the development of oral aspergillosis in adult leukemia patients.

A case of eosinophilic granuloma of the soft tissue arising in the palate of a 65-year-old man is reported. It was an elastic hard lesion measuring about 10mm in diameter. The lesion was removed under a clinical diagnosis of fibroma. Histologically, the lesion was diagnosed as an eosinophilic granuloma of the soft tissue.Ultrastructurally, viruses similar to the herpes virus group, with a diameter of 100nm, were observed in the cytoplasm of histiocytes. These cells were positive for HSV (Herpes Simplex Virus)-Type I antibody on immunostaining. The findings indicate that the lesion was caused by Type I allergy due to HSV Type I infection.

Glandular odontogenic cyst (GOC) is a rare jawbone cyst of odontogenic origin, first described by Gardner et al. in 1988. GOC is characterized by typical histopathological features, a gradual increase in size, and a high rate of local recurrence if not adequately treated. We report a case of GOC occurring in the anterior region of the mandible. The patient was a 62-year-old woman who presented with swelling of the anterior region of the mandible. Panoramic radiography indicated a multilocular radiolucent lesion in the anterior region of the mandible. Enucleation of the cyst was performed. Postoperative healing was satisfactory, and no recurrence has been noted on long-term observation. We reviewed 41 cases of GOC that had beenreported previously. Among these cases, 35 were located in the mandible and only 6 in the maxilla. The male: female ratio was 1.28 (23: 18), and the mean age was 47.8 years. Radiographically, among a total of 37 cases, 18 were unilocular and 19 were multilocular. The overall recurrence rate was 19.5%.

A glandular odontogenic cyst (GOC) is a rare odontogenic cyst, classified as a new developmentalodontogenic cyst by the WHO in 1992. It frequently arises in the anterior region of the mandible. Histopathologically, GOC is lined by epithelium of varying thickness, which contains mucous cells and vacuolations. Some casesshow clinically invasive growth, leading to a high rate of recurrence despite surgical excision. Some studies haveestimated that the overall recurrence rate is 27%.We report a case of GOC arising in the right mandibular third molar region. The patient was a 34-year-old man.Surgical excision was performed. One year 4 months after the operation, the prognosis was good, with no signs of recurrence.

Glandular odontogenic cyst (GOC) was first proposed by Gardner et al in 1988 as an infrequent developmental epithelial cyst occurring in jaw bones. We describe our experience with a case of GOC arising in the mandible and report the clinical course. The patient was 52-year-old woman with clearly bordered multilocular radiolucent lesions in bothsides of the mandibular premolar region. These cysts were extirpated, and the specimens were studied by routine pathological examination and immunohistochemical staining with cytokeratins. The diagnosis was established to be GOC. The cyst recurred 3.5 years after surgery, and reoperation was performed.

Glandular odontogenic cyst (GOC), first described in 1988 by Gardner et. al, is a comparatively rare jawbone cyst of odontogenic origin, which shares some features with both botryroid odontogenic cysts and mucous-producing salivary gland tumors. Although GOC has a high rate of recurrence, cases of recurrence have not been reported in the Japanese literature.This paper describes a case of GOC arising in the mandible of a 58-year-old man. The cyst recurred 12 years after primary treatment. Diagnosis and treatment of the lesion are discussed.

We report a case of glandular odontogenic cyst (GOC) arising in the mandible. The patient was a 55-year-old woman who presented with a painful swelling of the right premolar region of the mandible.Roentgenographic examination revealed a multilocular radiolucent lesion from the right first molar across themidline to the left second premolar region. The clinical diagnosis was a mandibular cyst. Enucleation of the cystand extraction of the teeth were performed with the patient under general anesthesia. Histological examinationshowed a multicystic lesion partially lined by non-keratinized epithelium with focal plaque-like thickening. Thesurface epithelium included eosinophilic cuboidal and ciliated cells. Cyst-like spaces and glandular structureswere also observed within the epithelium. Epithelial islands were also seen in connective tissue of the cyst.Immunohistochemically, epithelial cells were strongly positive for cytokeratin (CK) 13 and 19, but almost negativefor CK18. The histological diagnosis was GOC. The postoperative course was satisfactory, and no recurrencehas been noted 4 years 6 months after the operation.

In 1962, Kempe first described a clinical picture of children who have received physical abuse from their parents or foster parents as a battered child syndrome.We recently experienced a case of the battered child syndrome with oral candidiasis and mandibular fracture. A female infant of 1 year and 1 month post partum was referred to our hospital because of malnutrition and multiple unexplained trauma. Radiological studies revealed subdural hematoma and mandibular fracture, while the intraoral examination revealed extensive pseudomembrane and severe stomatitis.The patient was suspected of battered child syndrome and hospitalized so as to isolate from her mother. General management subsequently performed including chemotherapy, fluid therapy, blood transfusion and supply of nutrients saved the patient from death.

Paralysis of the mental nerve is one of the principal complications of surgery of the mandibular canal and mental foramen region. The position of mental foramen can be clearly depicted on CT scans. The mental foramen is bilaterally located at the mandibular premolar region and appears as a dimple on the bone surface. However, several reports have described an accessory mental foramen (AMF). We examined CT pictures taken from patients with implants for missing mandibular teeth to detect variations of the AMF. The results were follows: 1) AMFs were present in 28 patients (24.6 %). 2) Unilateral AMFs were found in 24 patients, and bilateral AMFs in 4 patients. 3) Among patients with unilateral AMFs, 21 had AMFs with one foramen, and 3 had AMFs with two foramens. Among patients with bilateral AMFs, 2 patients had one foramen on each side, and 2 had two foramens on one side. 4) The position of AMF relative to that of the mental foramen was as follows: 18 foramens were superior mesial, 8 were superior distal, 6 were inferior mesial, and 5 were inferior distal.These results suggest that one quarter of patients with missing mandibular teeth may have AMFs around the mental foramen.

In the present study, inorganic pyrophosphate (PPi), Mg, alkaline-phosphate activity (Al-pase), Ca, Pi and total protein in submandibular and parotid saliva were measured in 19 sialolithiasis and 61 age-matched control subjects in order to understand the possilbe etiologic factor (s) or disposition of this disease. The results can be summarized as follows:1. Saliva constituents in control subjects1) The concentrations of PPi and Mg, which are known to be potent inhibitors of calcium phosphate crystal formation, were significantly low in the submandibular gland as compared to those in the parotid. Since available clinical and statistical data on this kind of investigation so far performed show that sialolithiasis occurs most commonly in the submandibular gland, the lower inhibitory activity in this gland might be responsible for the formation of calculus.2) The concentrations of PPi, Ca and Pi in the submandibular saliva increased with age, while no distinct relationship was demonstrated between the concentrations of PPi, Ca and Pi and age. This finding seems not coincident with the clinical observation that sialolitiasis occurs most frequently in the second, third and fourth decades of life.3) As for saliva constituents, no significant difference was observed between males and females. This finding well coincided with the clinical observation that no sex difference exists in the incidence of sialolithiasis.2. Saliva constituents in patients with sialolithiasis1) With regards to all parameters examined, there was no significant difference between saliva constituents from non-diseased submandibular glands of sialolithiatic patients and those from normal subjects. This suggests that the submandibular gland in the non-diseased side functions normally even in patients with sialolithiasis.2) The diseased submandibular glands had significantly lower concentrations of Mg and Ca as compared to normal glands, which may indicate that some local disturbancees occur in the diseased submandibular glands from patients with sialolithiasis.3) The Al-pase activity in the diseased submandibular saliva from patients with sialolithiasis was considerably higher than non-diseased submandibular saliva from sialolithiasis and control subjects, In addition, the concentration of PPi showed a negative correlation to the Al-pase activity (r=0.822, P<0.05). It is assumed tha PPi may rapidly decomposed by high Al-pase activity, ultimately leading to crystal formation together with low Mg levels in the affected submandibular glands.

To clarify both the mechanism of parapharyngeal involvement of head and neck cancers and the clinical usefulness of parapharyngeal dissection, the routes of lymphatic flow from the oral cavity and oropharynx to the parapharyngeal space were studied using activated carbon particles CH40.The following results were obtained:1. Lymphatic flow from the posterior portion of the oral cavity and that from the oropharynx reach the parapharyngeal space through lymphatic channels in the submucosa.2. Among 6 routes of direct parapharyngeal spread of head and neck cancers, the anteromedial inferior, anteromedial superior, medial central, and anterolateral routes were found to have direction-specific routes of lymphatic flow. The flow of the former 3 routes is high, and that of the later route is low. These routes of lymphatic flow were considered to be responsible for the frequent spread of cancers into the parapharyngeal space by direct extension.3. Lymphatic flow to the parapharyngeal space drains not only into the node of Kuttner but also into the parapharyngeal and retropharyngeal nodes through lymphatic vessels in the parapharyngeal space.4. Anatomically, these findings suggest that parapharyngeal dissection is very useful in the management of cancers that involve the parapharyngeal space.
