RESUMO
Bifid mandibular condyle (BMC) is an uncommon morphological variant of the mandibular condyle. Although authors have proposed various etiologies for BMC, no consensus has emerged. In addition, varying findings have been reported regarding the epidemiological parameters of BMC (e.g., prevalence, gender ratio, and age), possibly due to its low incidence. BMC is occasionally associated with symptoms of the temporomandibular joint, such as ankylosis, pain, and trismus; however, it is difficult to detect this condition on conventional radiographs. This study reports a case of BMC with radiographic findings, and reviews the literature on the epidemiology of BMC.

Wernicke's encephalopathy is a fatal neurological disease caused by thiamine deficiency. Many reports indicate that Wernicke's encephalopathy is caused by malnutrition. We report the case of a 79-year-old female patient who had a left masticator space and parapharyngeal space abscess who was diagnosed with Wernicke's encephalopathy. She reported problems while eating due to the presence of the abscess, but the true quantities of food she was ingesting were never assessed. Clinicians have a responsibility to provide adequate nutritional support by ensuring that patients receive adequate nutrition. Clinicians should also keep in mind that Wernicke's encephalopathy may occur in patients who experienced prolonged periods of malnutrition.

Clinical features of masticator-space abscess (MSA) are very similar to those of parotitis or temporomandibular disorder (TMD), making early differential diagnosis difficult. Local causes of MSA include nerve block anesthesia, infection after tooth extraction, and trauma to the temporomandibular joint (TMJ); the systemic cause is immunodeficiency. Odontogenic causes account for most etiologies, but there are also unusual causes of MSA. A 66-year-old male patient visited the emergency room (ER) presenting with left-side TMJ pain three days after receiving an acupressure massage. He was tentatively diagnosed with conventional post-trauma TMD and discharged with medication. However, the patient returned to the ER with increased pain. At this time, his TMD diagnosis was confirmed. He made a third visit to the ER during which facial computed tomographic (CT) images were taken. CT readings identified an abscess or hematoma in the left masticator space. After hospitalizing the patient, needle aspiration confirmed pus in the infratemporal and temporal fossa. Antibiotics were administered, and the abscess was drained through an incision made by the attending physician. The patient's symptoms decreased, and he was discharged.

Synovial sarcoma (SS) is a malignant soft tissue tumor comprising 5-10% of all soft tissue sarcomas. This tumor normally occurs in the paraarticular regions of the extremities but is rare in head and neck sites. SS is sometimes difficult to diagnose because it can mimic benign lesions both clinically and radiologically. This paper presents a rare case of a SS of the buccal space of a 25-year old man. The histology examination and immunohistochemistry of the mass led to a diagnosis of synovial sarcoma. The patient was treated primarily with a surgical resection, followed by radiotherapy and chemotherapy. The follow up examination 17-months after surgery showed no signs of tumor relapse or metastasis.

Bisphosphonates are widely used to treat osteoporosis, hypercalcemia of malignant tumor. Despite their clinical benefit, bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a newly documented complication to patients receiving these drugs and first recognized by Marx in 2003. Thus, consideration of prevention and needs regarding unequivocal treatment regimen have emerged. Recently, several authors emphasized reports on appropriate clinical availability of surgical approach. It serves to concern about guideline for surgical and conservative treatment modalities. So, it is the purpose of this paper to review the current literatures about treatment regimens of BRONJ.

OBJECTIVE: In organotypic culture of immortalized human oral keratinocytes (IHOK), the change of the growth and differentiation was investigated according to the fibroblast type and the involvement of mitogen-activated protein (MAP) kinase. MATERIALS & METHODS: IHOK was cultured three dimensionally with gingival fibroblast (GF), dermal fibroblast (DF) and immortalized gingival fibroblast (IGF). We characterized biologic properties of three dimensionally reconstructed IHOK by histological, immunohistochemical, and Western blot analysis. We also investigated whether MAP kinase pathway was involved in epithelial-mesenchymal interaction by Western blot analysis. RESULTS: The best condition of three dimensionally cultured IHOK was the dermal equivalent consisting of type I collagen and IGF. IGF increased the expression of more proliferating cell nuclear antigen (PCNA), involucrin than GF and DF in response to co-culture with IHOK. Extracellularly regulated kinase (ERK) pathway was activated in organotypic co-culture with IGF. CONCLUSION: The organotypic co-culture of IHOK with dermal equivalent consisting of type I collagen and IGF resulted in excellent morphologic and immunohistochemical characteristics and involved ERK pathway. The epithelial-mesenchymal interaction was activated according to the fibroblast type.
