Abstract
Objective Hemifacial microsomia is a congenital abnormality that causes three-dimensional facial asymmetry, affection of the dental occlusion, and failure of growth of the midface in the growing child. This report outlines orthopedically induced condylar growth in a patient with hemifacial microsomia. Patient A 7-year-old girl with hemifacial microsomia, complete absence of the left mandibular condyle, and severe facial asymmetry was treated orthopedically in an early stage by means of a functional appliance. Functional therapy was instituted to stretch the deficient soft tissues to guide and promote skeletal growth and stimulate the affected areas. The treatment was completed with fixed appliances. Results The effect of the therapy was an excessive change in condylar growth in the affected side. Facial asymmetry was corrected and a symmetric mouth opening was established. Conclusions The treatment of patients with hemifacial microsomia should be initiated early enough so that the stimulus could in some degree normalize the deficient tissues and induce bone apposition, and in some cases surgical intervention could be avoided.

Abstract
UNLABELLED It has been proposed that bisphosphonates cause osteonecrosis of the jaws through impairment of the monocyte population function and proliferation. Such changes have been confirmed in jaw tissues, ex vivo. In this clinical study, we report for the first time a similar pattern of changes in peripheral blood monocytes. INTRODUCTION The aim of this study is to examine the effect of zolendronic acid administration in the peripheral blood white cell population, seeking a plausible pathophysiological link between bisphosphonates and osteonecrosis of the jaw. METHODS Twenty-four breast cancer patients, under zolendronic acid treatment for bone metastasis, were included. Peripheral blood samples were obtained prior to and 48 h following zolendronic acid administration. Flow cytometry gated at leukocyte, monocyte, and the granulocyte populations for the CD4/CD8/CD3, CD3/CD16+56/CD45/CD19, CD14/CD123, and CD14/23 stainings were performed. RESULTS We were able to record a number of changes in the white cell populations after 48 h of zolendronic acid administration. Most importantly, in the monocyte populations, we were able to detect statistically significant increased populations of CD14+/CD23+ (p = 0.038), CD14+/CD23- (p = 0.028), CD14+/CD123+ (p = 0.070, trend), and CD14+/CD123- (p = 0.043). In contrast, statistically significant decreased populations of CD14-/CD23+ (p = 0.037) and CD14-/CD123+ (p = 0.003) were detected. CONCLUSIONS Our results provide evidence supporting the hypothesis that bisphosphonate administration modifies the monocyte-mediated immune response. An increase of CD14+ peripheral blood monocyte (PBMC) populations along with a decrease of CD14- PBMC populations has been recorded. The latter finding is in accordance with limited-currently existing-evidence and warrants further elucidation.

Abstract
OBJECTIVE To detect immunohistochemically the N-cadherin expression in different types of benign and malignant salivary gland tumors in an attempt to note any possible correlation to their development, stage and invasive properties. MATERIALS AND METHODS N-cadherin expression was examined in tissue specimens from 49 salivary gland tumors including: pleomorphic adenomas (4), Warthin's tumors (10), and myoepitheliomas (4) (benign tumors), as well as adenoid cystic carcinomas (14), mucoepidermoid carcinomas (4), polymorphous low-grade adenocarcinomas (6), and adenocarcinomas not otherwise specified (5) (malignant tumors). Twelve specimens of normal salivary glands were used as control. The perineural invasion and stage of malignant salivary gland tumors were evaluated. Immunohistochemical procedure was performed automatically using the Bond Polymer Refine Detection Kit. RESULTS N-cadherin expression was not found in normal salivary glands. In benign salivary gland tumors, N-cadherin along membranes of neoplastic cells as well as in centrocytes of lymphoid germinal centers was seen in 1 and 4 cases of Warthin's tumors, respectively. Varied degree of N-cadherin expression was found in 13 (45%) cases of malignant salivary gland tumors. N-cadherin expression was significantly correlated with perineural invasion (χ(2) = 11.7, p < 0.0001), but not with stage of malignant salivary gland tumors. CONCLUSION N-cadherin expression was observed in malignant salivary gland tumors and could be an indicator of potentially aggressive behavior. N-cadherin expression by tumor cells could be attributed to perineural invasion.

Abstract
Starting from early stages of craniofacial development, the leading role of vasculature, in particular endothelial progenitor cells, becomes apparent. They are probably the cells that synthesize the appropriate bone morphogenetic protein (BMP), that precedes neural crest cell migration and determines their final destination and skeletal development. During postnatal osteosynthesis in the mandible, angiogenesis similarly goes before osteosynthesis, regulates this process with the production of BMP-2 and serves as a scaffold for osteoblasts. This growth factor is involved in bone metabolism and bone injury repair. The dependence of bone from vasculature, is better understood when looking to osseous changes that result from vasculopathies and arteritides, like in diabetes mellitus and polyarteritis nodosa respectively, that affect the mandible more frequently than previously suspected. These changes are not only the result of a dysregulation of osteoblasts and osteoclasts, but of a complex network of factors that affect the vasculature, like VEGF and hypoxia. Abnormal vasculature results in qualitatively degradated bone, with an atypical architecture or even in bone necrosis. The dynamic interplay between vasculature and bone of the mandible, with the vasculature endothelium playing an initiating and regulatory role in osteosynthesis, supports the hypothesis of an angiogenic origin of bone. This hypothesis, helps in understanding of bone pathology, like avascular necrosis and of the impact of interventions and medications that affect vasculature, on bone metabolism.

Abstract
BACKGROUND Targeted cancer therapy is a new approach for the treatment of cancer. It involves a specific molecular target, mainly a receptor that serves as a target for monoclonal antibodies or tyrosine kinase inhibitors. Side-effects of these new regimens are described to be mild, compared to those of classical chemotherapy. There is a lack in the documentation and understanding of oral complications related to molecularly targeted drugs. METHODS In this review, we tried to make a systematic review of the databases Pubmed and Scopus, using "targeted cancer therapy" and "oral", or "mucositis", or "stomatitis", or "bleeding", or "hemorrhage" as search terms. Specific drug name searches were not conducted. The search yielded 97 results. Only articles related to EGFR and VEGFR inhibition were selected. Finally 13 articles met the criteria. RESULTS are discussed and possible pathogenetic mechanisms for the complications of targeted cancer therapy regimens are presented. RESULTS It appears that the most serious side-effect is mucositis/stomatitis that may affect the whole gastrointestinal tract. It rarely results in treatment discontinuation. Reduced saliva secretion, xerostomia and dysphagia can be severe with some regimens and interfere with food uptake. Osteonecrosis, wound healing impairment, spontaneous gingival bleeding and dysgeusia were also reported. CONCLUSIONS Considering these data it is obvious that symptoms related to cancer treatment should be considered in the context of the holistic management of patients. Oral complications should not be ignored but recorded during physical examination, because they may significantly impair daily activities and patients' quality of life.

Abstract
The lip is estimated to be the most frequent location for carcinoma of the oral cavity. It occurs more frequently in men, especially those with a history of exposure to sunlight. Despite the usually effective management, regional and occasionally distant metastases do occur, especially in advanced stages. In this retrospective analysis of patients with labial carcinoma presenting with distant bone metastases in 1995-2003, the extremely limited number of patients did not allow for multivariate data analysis. From a cohort of 415 patients presenting with lip lesions, 186 cases were diagnosed as carcinoma and managed accordingly. Four patients (2.14%) showed distant bone metastases, one with concurrent axillary node metastasis. Patient demographics, tumour characteristics, case management and survival were evaluated. The distant metastasis patients were of clinical stages II-IV; initial management was wide local excision with reconstruction for all cases, with one undergoing concurrent neck dissection and one adjuvant radiotherapy. Time for distant bone metastasis was 9-21 months, subsequent survival 3-14 months and overall survival 13-35 months. Distant metastases from labial carcinoma are rare, not exceeding 2%. Metastasis to bone and axillary lymph nodes is exceptionally rare and can be attributed to either inadequate initial management or aggressive tumour behaviour.

Abstract
Cancer of the anterior faucial pillar-retromolar trigone is an uncommon head and neck tumor, which has historically been shown to be associated with poor prognosis. In this retrospective study, we reviewed our experience with primary surgery followed by postoperative radiation therapy in order to determine the impact of our treatment protocols on patients' outcome. Between January 1994 and December 1998, 31 patients with histologically proven squamous cell carcinoma (SCC) of the anterior faucial pillar-retromolar trigone were treated in our department. Surgical excision of the primary lesion and ipsilateral neck dissection were performed in all patients. Reconstruction was accomplished using masseter muscle flap or tongue flap. Postoperatively, most patients (90%) received radiation therapy (51-58 Gy) to the primary side and neck. Adjuvant chemotherapy was offered if histologic signs of aggressive behavior were identified. Four out of 31 patients were initially seen at stage I or II and 27 patients at stage III or IV of the disease. Metastatic disease was demonstrated in 78% of ipsilateral neck nodes. Occult metastases were found in 64% of clinically N0 necks. The 3-year loco-regional recurrence rates were 44.8%. SCC of retromolar trigone is considered as an aggressive and insidious tumor. The reconstruction of the deficit of the anterior faucial pillar-retromolar area with masseter muscle flap is a reliable, safe and absolutely functional method.

Abstract
Removal of deep-lobe parotid tumours from the parapharyngeal space is often difficult because of limited surgical access and the critical vascular and neurologic structures nearby. Mandibulotomy, when necessary, is useful for improving wider visibility and control of the vascular bundle and facial nerve, but may cause damage to the inferior dental and lingual nerves. The double mandibular osteotomy with coronoidectomy gives excellent access and avoids damage to these nerves.

Abstract
PURPOSE General consensus has been reached on extracting mandibular third molars when they are involved in pathologic processes. However, early extraction is advisable in cases of eruption disturbances of the mandibular second molar, before or during orthodontic treatment. METHODS Thirty-two patients with early extraction of the mandibular third molar before or during orthodontic treatment were examined. RESULTS In these cases either the presence of the third molar presented an obstacle in the eruption path of the second, or third molar germ removal was considered beneficial to the course of orthodontic treatment. CONCLUSIONS Early extraction of the mandibular third molar facilitates the eruption of the second molar, especially in cases where evidence of crowding and lack of space in the posterior mandibular region exist. Orthodontic treatment may, in some cases, aggravate eruption disturbances of the second molar.

Abstract
Metastases to the jaws and oral soft tissues are rare. A case of breast angiosarcoma metastatic to the mandible and the gingiva, bilaterally in the premolar area is presented. The clinical, histological features and the management of the metastatic oral lesions are reported. Our case emphasises the possibility that in patients with history of breast angiosarcoma, oral inflammatory-like lesions may be an indication of a metastatic deposit.

Abstract
Bleeding from the external auditory canal following head trauma is not unusual. It can be caused by a posterior dislocation of the mandibular condyle associated with a fracture of the tympanic bone. Although posterior dislocation is uncommon, it is the second most frequent complication after antero-medial displacement of the condyle. We report four cases of tympanic plate fracture and present CT images demonstrating the range of injuries seen.

Abstract
Although the sphenoid sinuses can be identified in sections of the fetus at 4 months, at birth the sinus remains small and is little more than an evagination of the sphenoethmoid recess. After the 3rd year, invasion of the sphenoid bone is more rapid, and by the age of 7, the sinus has extended posteriorly to the level of the sella turcica. By the age of 12, the sphenoid pneumatization reaches its final form and a size equivalent to the adult, although further enlargement into the basisphenoid may occur in the adult. Agenesis of paranasal sinuses is an uncommon clinical sign and refers mainly to the frontal and secondarily to the maxillary sinuses. Agenesis of sphenoid sinuses is a very rare phenomenon in the literature. We present a 32-year-old male patient with agenesis of sphenoid sinuses that was studied by CT.

Abstract
UNLABELLED A case of a 5-year-old girl is described whose clinical features included postnatal growth retardation, microcephaly and characteristic facial appearance. These are recognized as the main features of the Dubowitz syndrome. Apart from these features, our patient had recurrent infections of the sinopulmonary tract, high serum IgE levels, defective chemotaxis of polymorphonuclear cells and defective antibody response, findings characterizing the hyper-IgE syndrome. The co-existence of these two syndromes is rare and we suggest that this is the first such case in the literature. CONCLUSION Patients with the Dubowitz syndrome will Dubowitz syndrome will require long-term follow up because there is a considerable risk for the syndrome to co-exist with primary immunodeficiency or for malignancies to develop.

Abstract
This study was designed to examine the pathogenesis of bromodeoxyuridine-induced (BrdU) clefts of the secondary palate in mice. Intraperitoneal injections of BrdU (500 mg/kg body weight) were given on days 11 and 12 to some pregnant mice and on days 12 and 13, and days 11, 12 and 13 to others. Evaluation of craniofacial relations and palate development in BrdU-treated mice revealed inhibition of vertical development of the palatal shelves, mandibular hypoplasia which led to failure of downward displacement of the tongue and the creation of an obstacle to reorientation of the palatal shelves. The results of this study demonstrate a strong correlation between induction of cleft palate and the presence of structural alterations in the mandible, and the mechanism of BrdU-induced cleft palate resembles the defect in the Pierre Robin anomaly.

Abstract
Chronic idiopathic hyperphosphatasemia, or juvenile Paget disease is a very rare syndrome that is characterized by fragile bones, bowing deformities, shortness of stature, large head, premature loss of teeth, radiographic evidence of expanded osteoporotic long bones with coarse trabeculations, and widened bones of the skull. Increased levels of serum alkaline phosphatase and increased levels of urinary total hydroxyproline are notable. We present a case of juvenile Paget disease that was associated with a history of precocious puberty. The patient had odontogenic osteomyelitis of the mandible that was treated by drainage, surgical debridement and antibiotic therapy.

Abstract
Transverse sphenoidal fractures may be associated with a variety of skull base injuries and neural deficits. Among those nerve injuries, oculomotor palsies and particularly sixth cranial nerve palsy, are quite common. Blows on the side of the head in the squamous temporal region may run across the floor of the middle cranial fossa through the greater wing of the sphenoid in the transverse cranial axis. We report three cases of patients who had sustained craniofacial injury which included a transverse fracture of the middle cranial fossa through the sphenoid sinus, extending to the petrous apex and producing abducent, facial, and eighth nerve dysfunction. Spontaneous recovery from diplopia occurred in all cases within 4 months. The management of the patients and the patterns of transverse cranial base fractures and their associated clinical features are discussed.

Abstract
Sagittal or vertical fractures of the mandibular condyle and chip fractures of the medial part of the condylar head are very rare entities and their identification is difficult with conventional radiographs. We report a case of a unilateral bifid mandibular condyle which resulted following a sagittal condylar fracture. This was associated with a chip fracture of the medial part of the condylar head on the contralateral side. These types of condylar fracture do not require any surgical treatment, but early mobilization is indicated.

We report a growth retarded, male child with exomphalos, bilateral direct inguinal hernias, unilateral renal agenesis, congenital heart defect, costovertebral dysplasia, microcephaly, ventricular septal defect, and paroxysmal supraventricular tachycardia associated with Wolff-Parkinson-White syndrome. The natural history of that syndrome is poorly understood and provisional suggestion of a new syndrome will depend on further similar observations.
