Abstract
There is experimental evidence that tumour invasiveness, progression and metastasis of most solid tumours are angiogenesis-dependent. The onset of the angiogenic tumour cell phenotype behaves as an independent event during malignancy, and the switch from a prevascular to a vascular phase may be achieved by several mechanisms. From experimental data it is reasonable to think that determination of angiogenic activity is a marker of tumour aggressiveness and metastasis in human solid tumours. In particular, determination of tumour angiogenesis seems to be a potential new marker for prognosis, to recognize low versus high risk patients. On the above basis, recently, several clinical studies have been done to correlate the degree of intratumoral vascularisation, detected by immunocytochemical methods, with metastasis and/or prognosis. Overall, the majority of these studies found a significant correlation between microvessel density of the primary tumour and presence of metastasis in the human rumours tested (breast, non-small cell lung, prostatic and head and neck cancers and skin melanoma). Much experience has been obtained for early-stage breast carcinoma. In this tumour, vascular index is emerging as a novel important prognostic tool, particularly useful in identifying high risk node-negative patients eligible for systemic adjuvant therapy. Because angiogenesis-inhibitor drugs are beginning to be used in clinical trials, the knowledge of the individual angiogenic activity of the tumours may be used in the future also as a marker to predict response to such a novel therapeutic approach. The methods to assess tumour vascularisation, clinical results, open questions and future perspectives are presented and discussed.

Abstract
The study was undertaken to determine the clinico-pathobiological characteristics in a series of 49 patients who developed metachronous breast carcinoma. Possible differences between the two tumours of conventional clinico-pathological features and of some biological markers such as DNA ploidy, c-erbB-2 oncoprotein overexpression and tumour angiogenesis were evaluated. The McNemar's test for independence showed that all the characteristics analyzed between the two tumours, in the same case, were not significantly different. After a median follow-up time of 69 months the overall survival of the series was 87.5% and the only significant prognostic factor for clinical outcome was peritumoural lymphatic vessel invasion (PLVI). The median second tumour-free interval was of 32 months ( 13 to 160 months) and none of the variables analyzed on the first primary was predictive of the timing of appearance of the second tumour. To assess the association between the characteristics of the first tumour and the odds of developing a metachronous carcinoma a case-control analysis was conducted. For each woman of the present series who developed bilateral cancer (case) a woman who had unilateral breast cancer (control) was matched for the length of the follow-up. A log-logistic regression model for matched sets was also performed to assess the risk of developing the second tumour. Applying multivariate analysis we found that progesterone receptor (PgR) status was the most important prognostic factor for the odds of bilateral tumour (odds ratio 0.22, p=0.013) followed by histological grade (odds ratio 0.20, p=0.063) and presence of PLVI (odds ratio 3.13, p=0.067). These findings suggest that the knowledge on the initial primary of PgR, grading and PLVI could be important to assess the individual risk of developing metachronous breast cancer. The determination of these factors could improve our ability to identify subsets of patients operated for breast cancer with different risks for bilateral tumour, allowing for a better selection of those patients who need intensive surveillance of their contralateral breast, and eligible for chemoprevention.

Abstract
The protocols for clinical evaluation and management of children with complex craniosynostoses are significantly different from those used in single suture forms. The time at which the various anatomical and functional anomalies observed in the affected subjects become clinically relevant varies from patient to patient, consequently requiring a tailored approach. The clinical course is variable and influenced by multiple factors, acting at different steps of the children growth. Intracranial hypertension is a major concern already in the first months of life; active cerebrospinal fluid (CSF) dynamics disorders, venous hypertension, and progressive craniocerebral disproportion are considered the main pathogenetic factors. Cranial vault and skull base sutures synostoses account for the frequently observed increased venous pressure. Skull base abnormalities lead to upper airways obstruction, which, on one side, might create significant upper airways obstructive problems and, on the other, contribute to the increase in the intracranial pressure. Secondary Chiari malformation is common and considered as a progressive disorder, mainly due to progressive craniocerebral disproportion, venous hypertension, and CSF dynamics disorders. Optic nerve and orbit-related eye-globe diseases are also a major concern. Papilledema is mostly related to increased intracranial pressure. The skull base synostotic process is the base of significant abnormalities of the orbital space, ending in the common feature of significant proptosis with the consequent risk of corneal ulcers. Aims of this paper are to analyze the physiopathogenetic mechanisms at the base of the clinical manifestations presented by children with complex craniosynostoses, and the therapeutic options currently available.

Abstract
PURPOSE The use of distraction osteogenesis is the first option in the treatment of craniofacial hypoplasia. Both internal craniofacial distractor devices (ICDD) and external craniofacial distractor devices (ECDD) can improve visual and respiratory functions in patients with craniofacial synostosis significantly. They also improve the cosmetic outcome. DISCUSSION We reviewed the pertinent literature concerning the use of ECDD in complex craniostenosis. Surgical data as well as quality of life notes were analyzed and compared with those reported for ICDD. CONCLUSION The advantage of ECDD compared with ICDD is the easier application and postoperative management as compared with ICDD, with comparable results for extent and quality of distraction osteogenesis. The disadvantage is the quality of life which most authors report is worse if compared to ICDD during the distraction osteogenesis period.

Abstract
PURPOSE This study aimed to evaluate our experience in treating cranio-maxillo-mandibular malformations with hypoplasia of the upper and middle third of the face. We wished to determine a new diagnostic path involving a new clinical questionnaire for obstructive sleep apnea (OSA) evaluation, which we have developed by merging existing tests, literature findings, and our clinical experience to obtain a high level of information with minimal cost. This questionnaire is an improvement of the other anamnestic tests in the literature. METHODS The study was carried out on 17 pediatric patients affected by syndromic craniofacial malformations and treated with surgical advancement of the middle third of the face, associated with or without upper third advancement, through osteodistraction. We used the obstructive airway child test (OACT) for clinical evaluation. The OACT is an OSA assessment test based on questions proposed to the patient's relatives. All patients underwent polysomnography for instrumental assessment of OSA. These patients were also required to have a computed tomography scan for surgical planning. At the start of the treatment, 11 patients had severe OSA, 4 patients had moderate OSA, and 2 patients had slight OSA. RESULTS At the end of the treatment, 6 patients had slight OSA and 11 patients had no OSA; these data were confirmed with OACT and polysomnography. CONCLUSIONS Based on our results, we suggest the following flowchart: OACT for OSA clinical evaluation; CT scan for evaluation of the volume of the rhinoropharyngeal air column, anatomical obstruction detection, and surgical planning; and polysomnography for diagnostic confirmation.

Abstract
Coloured bone cements have been introduced to make the removal of cement debris easier at the time of primary and revision joint replacement. We evaluated the physical, mechanical and pharmacological effects of adding methylene blue to bone cement with or without antibiotics (gentamicin, vancomycin or both). The addition of methylene blue to plain cement significantly decreased its mean setting time (570 seconds (sd 4) vs 775 seconds (sd 11), p = 0.01), mean compression strength (95.4 MPa (sd 3) vs 100.1 MPa (sd 6), p = 0.03), and mean bending strength (65.2 MPa (sd 5) vs 76.6 MPa (sd 4), p < 0.001) as well as its mean elastic modulus (2744 MPa (sd 97) vs 3281 MPa (sd 110), p < 0.001). The supplementation of the coloured cement with vancomycin and gentamicin decreased its mean bending resistance (55.7 MPa (sd 4) vs 65.2 MPa (sd 5), p < 0.001).The methylene blue significantly decreased the mean release of gentamicin alone (228.2 µg (sd 24) vs 385.5 µg (sd 26), p < 0.001) or in combination with vancomycin (498.5 µg (sd 70) vs 613 µg (sd 25), p = 0.018) from the bone cement. This study demonstrates several theoretical disadvantages of the antibiotic-loaded bone cement coloured with methylene blue.

Abstract
BACKGROUND Anterior cranial plagiocephaly, depending on the early hemicoronal suture fusion, is the most relevant form of plagiocephaly in terms of clinical implications. Its estimated incidence ranges between 0.4 and 1 per 1,000 live births. In the present report, we aim at validating the classification of Di Rocco and Velardi, proposing a scheme based on basicranium analysis using CT scans and its predictive value by evaluating the developmental characteristics of a population of adult subjects affected by anterior plagiocephaly who had underwent the surgical correction in the first months of life. MATERIALS AND METHODS The group of patients here considered was retrieved from among all patients operated upon for craniostenosis in the pediatric neurosurgery unit of Policlinico Gemelli in Rome between January 1, 1980 and December 31, 1989. The study group consisted of 13 patients, seven females and six males, affected by anterior synostotic plagiocephaly ranging in age between 20 and 32 years (mean 25.54 years). We also formed a group of unaffected patients in order to control for normal variability in the population. The subjects of the study group were evaluated using CT scan exams and cephalometric analyses were performed using three-dimensional reconstruction. DISCUSSION AND CONCLUSION In this study, we were able to associate a facial phenotype to confirm the predictive value of the classification proposed. It is highly probable that the different outcomes depend on the different degrees of involvement in the synostotic process by the various skull base sutures which were essentially unaffected by the surgical procedures.

Abstract
AIM To assess the activity and safety of non-pegylated liposomal doxorubicin (Myocet®) in combination with docetaxel and trastuzumab as first-line treatment of patients with HER-2/neu-positive metastatic breast cancer (MBC). PATIENTS AND METHODS The maximum tolerated dose of the combination was defined in the phase I part of the study. In the phase II part, 45 HER-2/neu-positive MBC patients were enrolled to receive 6-8 cycles of Myocet® 50 mg/m2 (day 1), docetaxel 30 mg/m2 (days 2 and 9) plus trastuzumab (day 2, 4 mg/kg followed by 2 mg/kg/week) every 21 d until unacceptable toxicity or progression occurred. Objective response (primary end-point) and treatment tolerability were assessed according to World Health Organisation criteria. Cardiotoxicity was defined as signs and/or symptoms of congestive heart failure and/or a decrease in left ventricular ejection fraction (LVEF). RESULTS The overall response rate was 55.6% (complete response 8.9%, partial response 46.7%), with a median time-to-progression of 10.9 months (C.I. 8.7-15.0). Median overall survival was not reached. The most frequent grade 3-4 adverse events were granulocytopaenia (60.0%), leukocytopenia (43.2%) and alopecia (35.6%). Grade 3-4 diarrhoea, pain, oral and skin toxicity (4.4%, each) and nausea/vomiting, thrombocytopenia and elevated alkaline phosphatase (2.2%, each) were also reported. In 2 patients LVEF fell to <50%, with a decrease from baseline>15%. LVEF median values remained stable from baseline to the end of the study (60%). CONCLUSIONS The combination of Myocet®, docetaxel and trastuzumab is safe and shows promising activity as first-line treatment of HER-2-positive MBC.

Abstract
There are few studies on maxillomandibular skeletal alterations. Twenty-one patients with unilateral coronal craniosynostosis were analysed and compared with controls. Landmarks analysed were: sella-nasion-point A and B angles, point A-nasion-point B angle, interincisal angle, angle of superior incisor axis on the sella-nasion plane, lower incisor to mandibular plane angle, Frankfort mandibular plane angle, zygomatic-frontal suture (Z), point on the most concave part of pyramidal apophysis of the upper maxilla (Mx), antegonial incisure (AG), upper (UMT) and lower (LMT) molar teeth. Differences were significant for class II dentoskeletal occlusion (p<0.0001), mandibular hyperdivergence (p<0.0001), lingualization of superior incisor (p<0.005), deviation of inferior interincisal contralateral line to the synostosis (p<0.0001) in the plagiocephalic population. Compared with contralateral counterpoints, Z (p<0.05), Mx (p<0.005) and UMT (p<0.0005) on the affected side were closer to the midline; AG (p<0.0005) and LMT (p<0.05) were further from it. On the frontal plane, Z, Mx, UMT, LMT and AG on the affected side were higher. Vertical and transversal contraction of the jaw of the synostotic side and laterodeviation of the mandibular interincisal line of the contralateral synostotic were clear. The altered position of the glenoid cavity, anteriorized in unilateral coronal craniosynostosis, could be the cause of mandibular dentoskeletal asymmetry.

Abstract
Oligodontia may compromise the harmonious development of the masticatory system. The quantity and quality of agenesis determines the type of approach and the complexity of rehabilitative therapy. We present a case of a patient affected by oligodontia and maxillo-mandibular skeletal alterations, corrected by orthodontic and orthognatic surgical treatment, assisted by prosthetic-presurgical rehabilitation of the lower arch. After surgery the occlusion was finally restored by a definitive prosthesis modeled on the presurgical one and supported by the same residual dental elements. Photographic and cephalometric analysis have shown the stability of the results at 20 years follow-up. The case presented shows that the final prosthesis on the residual teeth in patients affected by oligodontia may represent a possible alternative to implanto-prosthetic rehabilitation, presenting lower cost and requiring less time for definitive occlusal rehabilitation.

Abstract
Insulin-like growth factor binding proteins (IGFBPs) are a group of secreted proteins, which bind to IGF-I (and IGF-II) with high affinity and modulate the biological actions of IGFs. Abundant evidence points the importance of the IGF-I/IGFBP system on both cell growth and differentiation. A role for the IGF-I/IGFBP system in the regulation of normal human cartilage has been previously reported. In this context, recent studies suggest an emerging role for IGFBPs in the failure of cartilage during osteoarthritis (OA). Indeed, increased IGFBP levels have been reported in both the articular cartilage and synovial fluid from patients with OA. Overexpression of IGFBPs, by altering the bioavailability and function of IGFs, is likely to deliver IGFs-independent signals for chondrocyte survival. This, at least in part, might explain the degenerative changes of the cartilage in OA. Further studies are necessary to clarify the mechanisms that cause the overexpression of IGFBPs in patients with OA. Advances in our understanding of the relationship between osteoarthritis and the IGF-I/IGFBP system may lead to new treatment strategies for this degenerative disease.

Abstract
Bisphosphonate-related osteonecrosis of the jaw (BRONJ) consists of an exposure of the jaw bone that persists for over 8 weeks in patients with positive history for bisphosphonates. Symptomatology is characterized by dull and ceaseless pain, and in advanced stages, the exposure of necrotic bone is evident, which is frequently associated with purulent secretions and faetor oris. Despite many different studies on BRONJ, there are no general guidelines to treat this disease. In this work, the authors present their experience in BRONJ conservative therapy with spiramycin by comparing the results achieved with amoxicillin and clavulanic acid. From January 1, 2008 to June 30, 2008, our department received 25 patients who were affected by osteonecrosis secondary to bisphosphonates. Thirteen had taken bisphosphonates for osteoporosis and 12 for malignancies. We divided the 25 patients into two groups: those who had not received any treatment and those who had received treatment. The first group of 13 patients had been treated only with spiramycin (S). The results from this group were only evaluated to test the efficacy of spiramycin and were not considered in the study. The second group of 12 patients had not undergone any previous treatment. This group was further divided in two groups of 6 patients each; one group was treated with spiramycin and the other with amoxicillin and clavulanic acid (ACA). The following criteria were used to evaluate the results of the study: pain, sensibility deficits, purulent secretion and bone exposure. All group results were evaluated according to the criteria chosen, and positive results were achieved in both groups S and ACA, such as reduction or disappearance of pain, sensibility deficits and purulent secretion and healing of bone exposition, although spiramycin showed itself to be more effective than the combination of amoxicillin and clavulanic acid. Spiramycin is a macrolide antibiotic with a wide spectrum of activity against Streptococci, Pneumococci, Diplococci, Gonococci and Staphylococci, which are typical in BRONJ. No resistance was indicated. Administration of the antibiotics can be intravenous, intramuscular, rectal or oral, which remains the most frequently used since spiramycin elimination also occurs with saliva and the antibiotic reaches high concentrations in the oral cavity where BRONJ is situated. Good compliance to the spiramycin regimen was observed in all three groups, with a general improvement in all of the parameters considered. In only two cases did patients have to undergo surgical curettage. The results showed that spiramycin can be a first choice drug in the treatment of BRONJ, and it should be strongly considered for patients where previous antibiotic therapy did not prove to be effective.

Abstract
OBJECT Patients submitted to surgical advancement of the upper and middle facial third might have a relapse of the skeletal retraction after the removal of the distractor devices. Clinical signs related to this process are usually represented by exophthalmos, Obstructive sleep apnea syndrome (OSAS) or prognathism; however, the analytic definition of the relapse is very difficult , conventional cephalometric methods being influenced by the spatial movement of "N" (nasion) or "Or" (orbital) points. The authors present a new cephalometric technique that could be used as a more objective mean of follow-up evaluation of patients undergoing craniofacial advancement. MATERIALS AND METHODS The cephalometric analysis proposed is based on angles, lines, areas and distances between BaS (Basion-Sella) axis and other craniofacial landmark points. We have defined this cephalometric technique as "BaS Analysis". CONCLUSION The "BaS analysis" is not influenced by splanchnocranium movements in the space; for this reason, it can be considered a useful method for cephalometric analysis in the follow-up of patients with craniofacial malformations.
