Abstract
Objective Angiogenic factor AGGF1 (angiogenic factor with G-patch and FHA [Forkhead-associated] domain 1) promotes angiogenesis as potently as VEGFA (vascular endothelial growth factor A) and regulates endothelial cell (EC) proliferation, migration, specification of multipotent hemangioblasts and venous ECs, hematopoiesis, and vascular development and causes vascular disease Klippel-Trenaunay syndrome when mutated. However, the receptor for AGGF1 and the underlying molecular mechanisms remain to be defined. Approach and Results Using functional blocking studies with neutralizing antibodies, we identified [alpha]5[beta]1 as the receptor for AGGF1 on ECs. AGGF1 interacts with [alpha]5[beta]1 and activates FAK (focal adhesion kinase), Src (proto-oncogene tyrosine-protein kinase), and AKT (protein kinase B). Functional analysis of 12 serial N-terminal deletions and 13 C-terminal deletions by every 50 amino acids mapped the angiogenic domain of AGGF1 to a domain between amino acids 604-613 (FQRDDAPAS). The angiogenic domain is required for EC adhesion and migration, capillary tube formation, and AKT activation. The deletion of the angiogenic domain eliminated the effects of AGGF1 on therapeutic angiogenesis and increased blood flow in a mouse model for peripheral artery disease. A 40-mer or 15-mer peptide containing the angiogenic domain blocks AGGF1 function, however, a 15-mer peptide containing a single amino acid mutation from -RDD- to -RGD- (a classical RGD integrin-binding motif) failed to block AGGF1 function. Conclusions We have identified integrin [alpha]5[beta]1 as an EC receptor for AGGF1 and a novel AGGF1-mediated signaling pathway of [alpha]5[beta]1-FAK-Src-AKT for angiogenesis. Our results identify an FQRDDAPAS angiogenic domain of AGGF1 crucial for its interaction with [alpha]5[beta]1 and signaling.

Abstract
BACKGROUND Klippel-Trenaunay Syndrome (KTS) is a genetic vascular malformation disorder which induces a variety of phenotypic expression in patients which differ in terms of severity/location. While previous studies have documented genitourinary (GU) complications in adult KTS patients, documentation of the scope and incidence of GU involvement in the pediatric population with imaging findings is currently limited. This study represents the largest KTS genitourinary review to date. OBJECTIVE To assess the incidence, scope, clinical findings and imaging characteristics of GU pathology in pediatric KTS patients. MATERIALS/METHODS Using a retrospective data analysis design, the charts and imaging studies of pediatric KTS patients were reviewed. All patients received care at a specialized vascular clinic within a multicenter tertiary care system. Variables studied included age, age at KTS diagnosis, gender, urologic involvement, and age of urologic complication. RESULTS 58 patients were identified. 33 were male and 25 were female. 10 patients had GU findings. Three of these patients had multifocal GU involvement (greater than 1 finding). Urologic manifestations were diverse with 9 distinct diagnoses involving 6 unique organs. Renal, vesical and scrotal pathologies were most common. Hematuria was the most common presenting symptom in 30% (3/10). Previously unreported findings (labial swelling, renal lymphatic cysts) were identified. The average age of KTS diagnosis was 4.9 years. The average age of documented GU complication and involvement was 7.6 years. CONCLUSION Significant GU complications due to KTS can occur in the pediatric population. Early clinical and imaging characterization of these conditions is important for management, family education and early intervention strategies.

Abstract
Individuals with acromegaloid physical appearance or tall stature may be referred to endocrinologists to exclude growth hormone (GH) excess. While some of these subjects could be healthy individuals with normal variants of growth or physical traits, others will have acromegaly or pituitary gigantism, which are, in general, straightforward diagnoses upon assessment of the GH/IGF-1 axis. However, some patients with physical features resembling acromegaly - usually affecting the face and extremities -, or gigantism - accelerated growth/tall stature - will have no abnormalities in the GH axis. This scenario is termed pseudoacromegaly, and its correct diagnosis can be challenging due to the rarity and variability of these conditions, as well as due to significant overlap in their characteristics. In this review we aim to provide a comprehensive overview of pseudoacromegaly conditions, highlighting their similarities and differences with acromegaly and pituitary gigantism, to aid physicians with the diagnosis of patients with pseudoacromegaly.

Abstract
3D image technology provides a very effective tool for evaluating, characterising, and drawing up the surgical treatment plan for potential orthognathic surgery patients. Patients with dysmorphic syndromes or incorrect jaw positions frequently show facial asymmetry. The objective of this cross-sectional survey is to evaluate facial asymmetry by means of three-dimensional computed tomography (CT) reconstructions. Twenty one consecutive patients were diagnosed using a CT scan. 3D reconstructions of the patients' skulls were made and then measurements taken of different craniometric landmarks and of the various structures presenting asymmetry. The gonion emerged as the most asymmetrical point in all subjects, and the anterior nasal spine showed least deviation. The t test produced statistically significant differences (p < 0.05) between symmetric and asymmetric patients at all landmarks. The lateral inclination of the mandibular ramus was shown to present the greatest asymmetrical deviation, followed by the frontal inclination of the mandibular ramus. The angulation of the mandibular ramus, on both frontal and lateral planes, determines apparent facial asymmetry, as well as conditioning the surgical treatment plan for patients with craniofacial asymmetry.

Abstract
We describe the orthodontic treatment of a patient with Klippel-Trenaunay-Weber syndrome (KTWS) who received orthodontic treatment that included rapid palatal expansion and orthognathic surgery. There is no report in the literature with this orthodontic treatment protocol, that was considered successful. The pros and cons of this approach as well as the risks involved are discussed.

Abstract
Klippel-Trenaunay-Weber syndrome is characterized by a triad of features, namely, vascular nevi, venous varicosities, and hyperplasia of hard and soft tissues in the affected area. Involvement of the orofacial region is uncommon, but nevertheless, a wide range of orofacial abnormalities may necessitate specialized dental and anesthesia management. We have documented the manifestations in 2 affected persons, outlined the nosology, reviewed the literature, and tabulated craniofacial anomalies and orodental complications. Special emphasis is given to the hematologic factors (bleeding tendencies) and vascular involvement (hemangiomata) which may significantly influence orodental management and anesthesia.
