IV3000 semi-occlusive dressing use in simple and complex fingertip injuries: efficacy and affordability.

OBJECTIVE: This study aimed to explore the efficacy of the IV3000 semi-occlusive, transparent adhesive film dressing in the non-surgical management of simple as well as more complex fingertip injuries. METHOD: In this qualitative study, patients with fingertip injuries were prospectively recruited and treated conservatively with the dressing between 2015 and 2017. Inclusion criteria included any fingertip injury with tissue loss and patient consent for non-surgical treatment consistent with the study protocol. Exclusion criteria included injuries needing surgical intervention for tendon injury or exposure, joint dislocations, distal phalangeal fractures requiring fixation, bone exposure, isolated nail bed lacerations and any patients eligible for surgical repair who did not wish to be managed conservatively. RESULTS: A total of 64 patients took part in the study. The patients treated with the dressing were asked to rate functional outcome, of whom 40 (62.5%) patients reported the outcome as 'excellent', 19 (29.7%) as 'satisfactory', five (7.8%) as 'indifferent' and none (0%) as 'unsatisfactory'. A reduced pulp volume at completion of healing was felt by 21 (32.8%) patients, but all patients were 'satisfied' with the aesthetic appearance of their fingertips at final clinical review. Average healing time was 4.5 weeks across the group, with the average time for return to work being just under one week. We estimate a 60% reduction in cost with the conservative versus the surgical management option. CONCLUSION: This study showed that, for participants, the IV3000 dressing was an affordable and effective option for the conservative treatment of simple fingertip injuries and in the management of more complex fingertip injuries.

Rare case of multiple and perforating pilomatrixomas in a young girl with lymphovascular malformation reveals a potential new disease association.

This report details the case of a girl of primary school age who was referred to our plastic surgery department with an ulcerating lesion on the nape of her neck. A firm mass was palpable in the underlying subcutaneous tissue. This lesion was accompanied by two smaller firm nodules: one in the adjacent tissue and another in the left preauricular region. Ultrasound and MRI demonstrated multiple calcified nodules confined to the subcutaneous tissue. An incisional biopsy of the ulcerating lesion confirmed a diagnosis of perforating pilomatrixoma; the lesion was subsequently excised, with no sign of recurrence at 3-month follow-up. The patient had a history of lymphovascular malformation (LVM) and a paternal history of Gardner's syndrome. Pilomatrixoma and Gardner's syndrome have a well-documented association in existing literature; aberrant Wnt/beta-catenin signalling is common to both. Recent laboratory studies suggest this pathway is also implicated in the pathogenesis of LVM.

Attitudes, Influences and Perceptions towards Plastic Surgery amongst Medical Students.

INTRODUCTION: Plastic surgery is a dynamic and evolving field but remains poorly understood due to lack of knowledge, media misconceptions and recent changes to medical undergraduate curricula. To address issues around student interest and recruitment into the speciality, it is imperative to understand the factors influencing medical students and future clinicians. AIMS: To examine influences, interest and perceptions of plastic surgery amongst Scottish medical students and explore methods to increase undergraduate engagement. METHOD: Cross-sectional survey distributed online via Scottish undergraduate medical school offices comprising 6 domains: demographics; career interest; perceptions, interests and influences in plastic surgery; curriculum and trainer views; understanding the role of a plastic surgeon; and undergraduate engagement. RESULTS: A total of 193 students responded with no statistically significant relationship between year group, gender, and interest in plastic surgery. Phrases most strongly identified with plastic surgery included private practice, reconstruction and cosmetics. Placements, teaching staff and workshops/courses were found to influence perception of plastic surgery. Fortunately, only 6% of students encountered antagonism towards plastic surgery encompassing themes of negative stereotypes of surgeons and connotations surrounding cosmetic surgery. Importantly, many students were largely unaware of the range of common procedures undertaken by plastic surgeons. To overcome this lack of awareness and generate greater interest, students suggested greater plastics exposure, consultant-led teaching and workshops showcasing the specialty. CONCLUSION: Medical students want varied, stimulating and flexible careers - something which plastic surgery can provide. However it seems the understanding of the scope of plastic surgery is poorly understood amongs future trainees. To increase uptake and interest, negative perceptions need to be addressed and greater engagement is required from medical school upwards.

Ruptured Achilles tendons show increased lectin stainability.

PURPOSE: To ascertain whether lectins could be a useful tool for investigation of the extracellular matrix of degenerated and normal tendons. METHODS: Hematoxylin-eosin-stained slides were assessed blindly using a semiquantitative grading scale for fiber structure, fiber arrangement, rounding of the nuclei, regional variations in cellularity, increased vascularity, decreased collagen stainability, hyalinization, and glycosaminoglycan, with a pathology score giving up to three marks per each of the above variables, with 0 being normal and 3 being maximally abnormal. For lectin staining with Aleuria aurantia, Canavalia ensiformis, Galanthus nivalis, Phaseolus vulgaris, Arachis hypogea, Sambucus nigra, and Triticum vulgaris, assessment of staining on a scale from 0 (no staining) to 5 (strong staining) was performed blindly. RESULTS: The mean pathology sum score of ruptured tendons (N = 14; average age 46.5 yr, range 29-61) was significantly greater than the mean pathology score of the control tendons of Achilles tendons from individuals with no known tendon pathology (N = 16; average age 62.5 yr, range 49-73) (pathology score: 18.5 +/- 3.2 vs 6.1 +/- 2.3). Four of the seven lectins used exhibited significantly positive results. CONCLUSIONS: Ruptured tendons were histologically significantly more degenerated than control tendons. Ruptured tendons showed different lectin staining properties than nonruptured ones. This difference may have resulted from posttranslational changes in the extracellular matrix producing alterations in the biochemistry of the tendon, which might interfere with the interaction with the lateral sugar residues of the collagen molecules or cause steric blockade.

Chondral metaplasia in calcific insertional tendinopathy of the Achilles tendon.

OBJECTIVE: To ascertain whether tendon samples harvested from patients with calcific insertional Achilles tendinopathy showed features of failed healing response, and whether abnormal quantities of type II collagen had been produced in that area by these tenocytes. DESIGN: Comparative laboratory study. DESIGN: University teaching hospitals. PATIENTS: Tendon samples were harvested from eight otherwise healthy male individuals (average age 47.5+/-8.4 years, range 38 to 60) who were operated for calcific insertional Achilles tendinopathy and from nine male patients who died of cardiovascular events (mean age 63.1+/-10.9 years) while in hospital. INTERVENTIONS: Open surgery for calcific insertional Achilles tendinopathy. MAIN OUTCOME MEASURE: Semi-quantitative histochemical, immunohistochemical, and immunocytochemical methods to ascertain whether tendinopathic tendons were morphologically different from control tendons, and whether abnormal types of collagen were produced. RESULTS: Tenocytes from tendons from patients with calcific insertional Achilles tendinopathy exhibit chondral metaplasia, and produce abnormally high quantities of collagen type II and III. CONCLUSIONS: The altered production of collagen may be one reason for the histopathological alterations described in the present study. Areas of calcific insertional Achilles tendinopathy have been subjected to abnormal loads. These tendons may be less resistant to tensile forces. Further studies should investigate why some tendons undergo these changes.
