    Despite recent developments in cleft surgery, management of primary unilateral cleft lip nose deformity has not yet been established. In this article, our treatment of nose deformity in an infant with unilateral cleft lip and palate (UCLP) by presurgical nasoalveolar molding (NAM) followed by primary cleft lip and nose repair is described.
    The authors performed relatively radical treatment of unilateral cleft nose deformity by repositioning the lower lateral nasal cartilage after dissecting it from the skin and/or lining through a nostril rim incision in the 1990s. Although outcomes achieved by the above procedures were acceptable, it was difficult to handle an infant's fragile cartilage even with open dissection. Recently, we adopted NAM for successful presurgical alignment of alveolar bone and correction of nasal deformity by medial and upward advancement of the nasolabial components to reposition the nasalis muscle and orbicularis oris muscle. These procedures result in more consistent postoperative outcomes.
    To assess the results of our treatment for UCLP nose deformity, the nasal forms of fifteen patients with complete UCLP (correction group) who were treated and followed for more than 1 year (1-5 years) were compared to those of 15 patients who did not undergo primary rhinoplasty (no correction group). All subjects of the correction group underwent presurgical orthopedic treatment with NAM, followed by lip repair using Cronin's triangular flap method with medial-upward advancement of nasolabial components with vestibular expansion using the cleft margin flap. Postoperative nasal forms including nostril height and width ratio, ratio of the height of the top of the alar groove, and curvature of the appropriate circle of the nasal alar groove were evaluated using color photos. Comparison of postoperative nasal forms demonstrated that the nostril height and width ratio and the height of the top of the alar groove in the correction group were significantly superior compared to those in the no correction group.
    Our management of cleft lip nose provides a good nasal form with minimum invasion in patients with UCLP. Long-term follow-up will be necessary to clarify effects on the growth of nasal tissues reconstructed in infancy. Furthermore, additional improvements in the technique of presurgical molding of deformed facial bones will be required in order to ensure a stable postoperative result.

    In the treatment of cleft lip and palate, factors such as the timing, method and sequence of lip and palatal closure, as well as the surgeon's skill are thought to markedly influence future maxillofacial development and speech function. Various treatments have been proposed, and many studies have been conducted to assess their usefulness, but no general consensus has been reached. Moreover, scientific studies have not necessarily been conducted to assess outcomes of all treatments.
    The present article deals with the outline of the six-center comparative study of treatment outcomes in Japanese patients with complete unilateral cleft lip and palate (Japancleft Project 2002-2005) and describes the need for, and benefits of collaborative, inter-center outcomes research to establish efficient and effective management for cleft lip and palate based on scientific findings.

    The present paper describes a global analysis of the numbers of manuscripts and presentations at international congresses in the fields of oral and maxillofacial surgery, oral pathology, and oral oncology. The following 4 international journals were selected: International Journal of Oral and Maxillofacial Surgery (IJOMS) , Oral Oncology (OO) , Journal of Oral Pathology and Medicine (JOPM) , and Oral Diseases (OD) during the past 10 years.
    1 ) The highest number of accepted papers in the 4 journals was from Japan, followed by the UK.
    2) Many participants at international congresses came from the organizing country and surrounding countries. Most guest lecturers or keynote speakers came from the UK, Germany, USA, and other European countries.
    3 ) Contributions to journals and congresses from developing countries have gradually increased, particularly from the People's Republic of China.
    4 ) Research and clinical activities in Japan based on the 4 international journals were at global levels; however, the numbers of selected guest or keynote speakers were insufficient.
    We should bring up talented persons with the global power of atttraction in this field.

    Platinum and fluorouracil (5-FU) chemotherapy is a common treatment for patients with oral cancer. Interstitial pneumonia has rarely been reported as a side effect of chemotherapy. We describe a case of interstitial pneumonia caused by nedaplatin and 5-FU treatment in a 63-year-old man with double cancer of the tongue and the lung. Two days after chemotherapy, blood tests revealed an elevation of C-reactive protein (CRP, 15.1 mg/dl). A chest X-ray film and computed tomography showed diffuse patchy shadows in both lung fields. Despite treatment with antibiotics, the CRP increased to 28.6 mg/dl, and the shadows became more pronounced by the fourth day. Drug-induced interstitial pneumonia was suspected. The patient was treated with steroids, and the shadows on his chest X-ray film improved. Twenty-seven days after chemotherapy, the patient received a partial tongue resection. We should pay much attention to the occurrence of the interstitial pneumonia caused by chemotherapy with platinum and fluorouracil, especially in patients with pulmonary diseases because they are at high risk. Early diagnosis and treatment are very important.

    We report a rare case of a foreign body reaching the neck following a stab wound in the oral floor. An 11-month-old infant stabbed the oral floor of his mouth with a pencil when he fell down from a bed. Under general anesthesia, we extirpated the object without severe postoperative complications. Chest X-ray films and computed tomography were useful for confirming the location of the tip of the pencil. The length of the pencil according to his mother differed from that from that on the images. This case suggested that information from the preoperative images was important for us.

    We describe a case of subclinical Sjögren's syndrome associated with systemic lupus erythematosus that was diagnosed because of preceding skin lesions observed during treatment for oral lichen planus.
    A 49-year-old woman had received treatment for oral lichen planus at a nearby dentist since April 2007. However, the patient was referred to our office in February 2008 after an unsuccessful course of treatment. Symptoms of xerostomia were not present during the initial visit. Erythema of the skin around the left inner canthus, present for about 20 years, increased and desquamation also occurred at about the same time. In addition, the fingers of both hands became erythematous. Therefore, we referred the patient to our dermatology department in June 2008. A skin biopsy showed infiltration of lymphocytes around the sudoriferous ducts, and a hematological examination was positive for anti-SS-A/Ro antibody. On the basis of a labial gland biopsy conducted in our office and the results of a Schirmer test and fluorochrome test conducted in our ophthalmology department, Sjögren's syndrome was diagnosed. About 1 year after presentation, the patient had systemic lupus erythematosus, and nephrosis syndrome developed.

    In the WHO classification of soft tissue tumors, solitary fibrous tumor (SFT) belongs to fibroblastic/myofibroblastic tumors with intermediate malignancy (rarely metastasizing). Although this tumor occurs mainly in the pleura, extrapleuratic tumors have been reported in ubiquitous sites, including the oral cavity, with a predisposition to the buccal region.
    We report a rare SFT arising in the upper lip. A 70-year-old man presented with a painless mass. MR images showed a homogeneously enhanced neoplasm. The tumor was resected surgically and exhibited the histopathological features of SFT. It consisted of collagen-forming, CD34-positive fibroblastic spindle cells in a haphazard arrangement, accompanied by a prominent hemangiopericytoma-like branching vascular pattern.
    Although there was no evidence of local recurrence or metastasis 1 year after sugery, long-term follow-up is mandatory because of the unpredictable behavior of SFT.
