Our results show that VEGF-C provides the preferred alternative for growth factor therapy of lymphedema when compared to VEGF-C156S, due to the superior lymphangiogenic response and minor blood vessel effects. Furthermore, these observations suggest that activation of both VEGFR-2 and VEGFR-3 might be needed for efficient lymphangiogenesis.

Objective: To study the safety and tolerability of Lymfactin R treatment combined with microvascular lymph node transfer surgery in patients with upper limb lymphedema. Background: Upper limb lymphedema is a common clinical challenge after breast cancer surgery and/or radiotherapy. Lymfactin R is an adenovirus type 5-based gene therapy involving expression of human vascular endothelial growth factor C (VEGF-C) in the damaged tissue. It aims to correct deficient lymphatic flow by promoting the growth and repair of lymphatic vessels.

Introduction: Maxillary advancement may affect speech in cleft patients. The aim of this study was to evaluate whether preoperative velopharyngeal (VP) function and cleft type can predict VP function after a Le Fort I maxillary osteotomy. Materials and methods: One hundred consecutive nonsyndromic cleft patients (54 females, 64 males) who underwent Le Fort I osteotomies were retrospectively evaluated. Pre-and postoperative VP function was assessed perceptually and instrumentally by a Nasometer. A five-point scale was used to rate velopharyngeal insufficiency symptoms (VPI 0e4). To assess reliability, 30 video recordings were reevaluated. Results: Preoperatively, 89% of patients had normal or insignificant VPI (0e1), and only 3% had moderate VPI (3). Postoperatively, 77% of patients had VPI values of 0e1 and 14% had moderate to severe VPI values (VPI 3e4). A positive correlation was found between pre-and postoperative VPI scores, whereas the cleft type did not affect speech results. Patients with a preoperatively normal VPI (0) were not at risk for postoperative velopharyngeal incompetence. Conclusions: There was an overall significant negative change in speech after a Le Fort I osteotomy. Atrisk patients presented with borderline (1) or more severe VPI (2 and 3) preoperatively.

Background Upper limb lymphedema is a common problem after axillary lymph node dissection. Lymphatic drainage can be improved by microvascular lymph node transfer, whereas liposuction can be used to reduce arm volume and excess of adipose tissue. We present the results of chronic lymphedema patients who have undergone lymph node transfer and liposuction simultaneously in 1 operation and compare the results with patients who have undergone lymph node transfer without liposuction. Methods During May 2007 to February 2015, 20 postmastectomy patients and 1 Hodgkin's lymphoma patient presenting with chronic nonpitting lymphedema (age between 37 and 74 years, average 56.7 years) were operated using the combined technique and 27 postmastectomy patients presenting with early-stage lymphedema (age between 31 and 68 years, average age 50.2 years) were operated using only the lymph node transfer. Compression therapy was started immediately after the operation and the patients used compression 24 h/d at least 6 months postoperatively. Changes in clinical parameters (number of erysipelas infections, pain), arm volume, transport indexes calculated form lymphoscintigraphy images, and daily usage of compression garments were compared preoperatively and postoperatively and between groups (combined technique vs lymph node transfer). The study was a retrospective observational study. Results In the combined technique group, the average arm volume excess decreased postoperatively 87.7%, and in 7 of 10 patients, the edema volume did not increase even without compression. Seventeen of 21 patients were able to reduce the use of compression garment. Lymphoscintigraphy results were improved in 12 of 15 patients and the improvement was significantly greater in the combined technique group than in the lymph node transfer group (P = 0.01). The number of erysipelas infections was decreased in 7 of 10 patients and the decrease was significantly greater in the combined technique group than in the lymph node transfer group (P = 0.02). In the lymph node transfer group, the average excess volume decreased postoperatively 27.5%. Fourteen of 27 patients were able to reduce the use of compression garments. Lymphoscintigraphy results were improved in 8 of 19 patients, and the number of erysipelas infections was decreased in 1 of 3 patients. Conclusions Liposuction can safely be performed with lymph node transfer in 1 operation to achieve optimal results in patients with chronic lymphedema. The combined technique provides immediate volume reduction and further regenerative effects on the lymphatic circulation. The significantly greater reduction in lymphoscintigraphy values and erysipelas infections suggests that the combined technique might be better for late-stage lymphedema patients than lymph node transfer alone.

Black Bone (BB) magnetic resonance imaging (MRI) is a nonionizing imaging method and a recent alternative to computed tomography (CT) in the examination of cranial deformities. The purpose of this study was to compare BB-MRI and routine 3D-CT in the preoperative evaluation of patients with craniosynostosis. Methods: At our center, we have routinely performed preoperative CT of the skull and brain MRI for patients with clinical suspicion of craniosynostosis. We recently changed our MRI protocol into one that includes sequences for the evaluation of both brain anatomy and skull bone and sutures by BB-MRI. A semi-automatic skull segmentation algorithm was developed to facilitate visualization. Both BB-MRI and 3D-CT were performed on 9 patients with clinical craniosynostosis, and the images were evaluated by two craniofacial surgeons, one pediatric neurosurgeon, and two neuroradiologists. Results: We obtained informative 3D images using BB-MRI. Six (6/9) patients had scaphocephaly, 1 (1/9) patient had unicoronal synostosis, and 2 (2/9) patients had lambdoid synostosis. The affected synostotic sutures could be identified both by BB-MRI and by 3D-CT in all patients. Intra-rater and inter-rater reliability for rating the calvarial sutures was high. However, the reliability for rating the intracranial impressions was low by both imaging methods.

The differential diagnostics between the common positional posterior plagiocephaly and relatively rare lambdoid synostosis is important due to the differences in their treatment plan and clinical management. However, the clinical criteria for the diagnosis of lambdoid synostosis are not clear since there is a considerable overlap in the features of positional posterior plagiocephaly and unilateral lambdoid synostosis. To systematically evaluate the clinical findings in these 2 patient groups, we quantitatively compared the characteristics of endocranial skull base and ectocranial calvarium in 3D computed tomography, in 9 children (mean age 2.9 years) with unilateral lambdoid synostosis and 9 children with positional posterior plagiocephaly. The groups were sex and age matched. Our results show that the skull bases in the lambdoid synostosis are posteriorly shorter and more twisted than in positional posterior plagiocephaly. Anterior twisting was mild in both skull types. Our study confirmed earlier suggested diagnostic feature: prominent ipsilateral mastoidal bossing downward and laterally in all lambdoid skulls. In positional posterior plagiocephaly the bossing was typically not detected. Interestingly, there was a great variation in the position of the ipsilateral ear and external auditory meatus in both patient groups. Thus, neither antero-posterior nor vertical position of ear is a reliable differential diagnostic feature between lambdoid synostosis or positional posterior plagiocephaly.
