27. The aesthetic items scale:A tool for the evaluation of aesthetic outcome after breast reconstruction

Author

Abstract

Background: Valid tools to assess aesthetic outcomes after breast reconstructive surgery are scarce. Previously a professional aesthetic assessment scale was introduced, the Aesthetic Items Scale (AIS). We aim to determine if this method is a valid and reliable tool to assess aesthetic outcome after breast reconstructive surgery. Methods: The study population was consenting women who underwent prophylactic mastectomy with subsequent implant-based breast reconstruction. The aesthetic outcome with regard to breast volume, shape, symmetry, scars, and nipple areola complex was rated on a 5-point scale using standardized photographs to give a summed total score. Photographs were evaluated by the patient, 5 plastic surgeons, and 3 mammography nurses. An overall rating of aesthetic outcome on a 1-10 scale was given separately. We determined the intraclass correlation coefficient and assessed interobserver agreement. To assess validity, we calculated the correlation between total score and overall rating of aesthetic outcome. Results: Interobserver reliability was highest between plastic surgeons for the subitem and overall scores and ranged between 0.56 and 0.82. The summed score of the AIS correlates strongly with the overall rating in professionals but not in patients. Conclusions: The AIS is a valid and reliable method for evaluating aesthetic outcome of breast reconstruction by plastic surgeons. The results indicate that patients judge aesthetic outcome differently, taking into account factors that are not represented in the AIS. Professionals can use this method to evaluate surgical results, but other measurements are needed to map satisfaction of the patient with her breasts.

31. Hyperosmolarity and hypoxia induce chondrogenesis of adipose-derived stem cells in a collagen type 2 hydrogel

Author

Abstract

Apart from soluble growth factors, various other biophysicochemical cues are known to promote chondrogenesis. Under physiological conditions, cartilage in the joint comprises a hyperosmotic and hypoxic environment. Therefore, in this study, we examined the inductive effects of hyperosmotic and/or hypoxic conditions on adipose stem cells (ASCs) and compared them with conventional TGFβ1-induction. After encapsulation in collagen type II hydrogels and specific induction, ASCs were assessed for viability, proliferation, morphology and chondrogenic differentiation potential. Viability was similar under all conditions, with low proliferative activity. After 4days, hypoxia and/or hyperosmolarity did not affect round cell morphology, while cells were mainly stretched in the TGFβ1-induced group. At 21days, the TGFß1-treated group had aggregated into a cell nodule. Hyperosmolarity mimicked this aggregation to a lesser extent, whereas cells under hypoxia stretched out after 21days, with a combined effect in the hypoxic/hyperosmotic group. Both individual and combined hyperosmotic and/or hypoxic conditions significantly upregulated SOX5, SOX9, COMP and Link-p gene expression compared with the non-induced group, and to similar levels as the TGFβ1-induced group. GAG synthesis in both hydrogel and medium was increased under hypoxic conditions, whereas hyperosmolarity decreased GAG formation in the hydrogels, but increased GAG formation in the medium. We conclude that in a joint mimicking the three-dimensional (3D) micro-environment, a combination of hyperosmolarity and hypoxia is able to induce chondrogenesis to the same extent as TGFβ1. This might lead to an interesting alternative when considering short-term triggering in a one-step surgical procedure for the treatment of cartilaginous defects.

34. Rupture of a flexor pollicis longus tendon in Scheie's syndrome. Case report

Abstract

We describe a case of Scheie's syndrome with a closed rupture of the flexor pollicis longus tendon, probably caused by a combination of extrinsic and intrinsic tendon changes. Early detection of carpal tunnel syndrome in all patients who have some form of mucopolysaccharidosis in which this is a universal occurrence (such as Scheie's syndrome), is recommended. Release of the carpal tunnel prevents long term complications, as described in this case report.

46. Interobserver reliability of the Mallet score

Author

Sluijs, Johannes A. van der, Doorn-Loogman, Mirjam H. van, Ritt, Marco J.P.F., and Wuisman, Paul I.J.M.

Abstract

The interobserver reliability of the Mallet score for active shoulder function was assessed by three experienced observers in a group of 30 children with an obstetric brachial plexus lesion (mean age 7.1 years, range 4.5–10 years). Interobserver reliability, measured using weighted κ, was good. Kappa varied between 0.37 and 0.84 and differed between the different aspects of the Mallet score and different pairs of observers. In decreasing order, mean weighted κwas 0.75 for abduction, 0.73 for hand to neck, 0.67 for hand to spine, 0.6 for external rotation and 0.53 for hand to mouth.
