ABSTRACT
OBJECTIVES: Nasoalveolar molding (NAM) was developed to facilitate easier treatment and better outcomes for cleft lip and palate (CLP) patients. The aim of this study was to investigate the parental burden and possible intercultural differences of this treatment modality, which is often argued to burden parents to an extraordinary amount. MATERIALS AND METHODS: Standardized questionnaires (available in English, Mandarin, and German) with 15 non-specific and 14 NAM-specific items to be retrospectively answered by Likert scales by parents of unilateral CLP patients with completed NAM treatment. RESULTS: The parents of 117 patients from two treatment centers in Taiwan and Germany were included. A very high level of overall satisfaction was found in both countries with significant intercultural differences in prenatal parent information, feeding problems, dealing with 3rd party's perception, and experienced personal effort. CONCLUSION: NAM is an effective treatment tool for children's CLP deformities and their caregivers in overcoming the feeling of helplessness. Intercultural differences may be due to infrastructural reasons, cultural attitudes and habits, or different public medical education. CLINICAL RELEVANCE: In addition to facilitating easier surgical treatment, NAM can be seen as a powerful coping strategy for parents dealing with a CLP deformity of their child and does not seem to burden them extraordinarily.

INTRODUCTION: The oral squamous cell carcinoma (OSCC) is a leading cause of death in human malignancies. The aim of this study is to integrate the CAM Assay as a reliable and good working in vivo model for the evaluation of OSCC tumor samples and its growth into the clinical work flow. MATERIAL AND METHODS: Fresh human Tumor samples (OSCCs) 1×1âcm in size were cut into 350-450µm thick slices by a Vibratome and put on the prepared CAM model.After growth of the tumor tissue on the CAM, we started with topical induction of proinflammatory cytokines (TNFα) and growth factors (TGFß). After further growth of the tumor on the assay, we explanted the tumor tissue and first performed microscopic and then immunohistochemical examinations. E-cadherin and vimentin were used as Epithelial-to-mesenchymal transition (EMT) -makers and the histologic preparations were evaluated histomorphometrically. The results were correlated with clinical parameters of the patients. RESULTS: Under TNFα, the small tumors (T1 / T2) show higher E-cadherin expression than larger tumors (T3 / T4). The vimentin expression under TNFα behaved in the opposite direction, at T1 / T2 the expression decreased in T3 / T4 increased. Furthermore, an increased E-cadherin expression in N0 and diminished E-cadherin expression in N1 / N2b patients could be detected depending on the N-stage of the patients. Vimentin, on the other hand, was reduced in the N0 group and expressed more frequently in the N1 / N2b group. TGFß induction also led to increased expression of vimentin in the T3 / T4 tumors and N1 / N2b stages. CONCLUSION: By integrating a CAM assay into the clinical workflow, tumors with preserved tumor architecture can be cultured and subjected to histological and molecular biology studies. Effects on biological behavior are recognizable and demonstrable in this model. The key markers E-cadherin and vimentin alone are not sufficient to represent the complexity of the EMT in this model. Further molecular biology and signaling pathway analyzes are necessary.

Wide awake local anesthesia no tourniquet (WALANT) hand surgery is a rapidly growing in popularity. WALANT has been used by hand surgeons when operating on bones, tendons, ligaments, nerve entrapments. We offer a case report of the first case in the literature describing WALANT technique when performing trapeziometacarpal joint arthroplasty with prosthesis implantation. We offer technical points on how to perform this procedure and the advantages that are associated with using WALANT for prosthesis arthroplasty.
