Protocol for an open randomised controlled trial investigating Fibrin Glue in Skin grafts for Skin cancer (FiGSS).

INTRODUCTION: Skin cancer is a common disease in the tropics, and oncological resection typically requires reconstruction with skin grafts. Fibrin glue, initially established as a haemostatic agent, has been studied extensively as an adhesive for skin grafts in burns. This study aims to investigate the use of fibrin as an adhesive for split skin grafts in skin cancers. METHODS AND ANALYSIS: The study design is a prospective randomised controlled trial with the aim of investigating the impact of two different methods of split skin graft fixation. The intervention of fibrin glue will be compared with the control of staples or sutures. The trial will be conducted at two sites, a public hospital and a private hospital in Townsville, Australia, over a 24-month period with 334 participants to be recruited. Consecutive patients presenting for skin excisions and grafting will be eligible to participate in this study. Randomisation will be on the level of the patient. The primary outcome is graft take based on wound healing at 1 month. Secondary outcomes will be pain on dressing changes and operative time. ETHICS AND DISSEMINATION: The study has been approved by The Townsville University Hospital Human Research Ethics Committee. Findings will be disseminated in conference presentations and journals and through online electronic media. TRIAL REGISTRATION NUMBER: ACTRN12618000484246.

Metastatic Merkel cell carcinoma and malignant melanoma in a single sentinel lymph node.

Merkel cell carcinoma (MCC) and malignant melanoma are aggressive skin cancers that usually arise in sun-exposed parts of the body. This report describes an 85-year-old man who underwent a wide local excision and sentinel lymph node biopsy for primary MCC and was subsequently found to have metastatic MCC and malignant melanoma within the left inguinal sentinel lymph node. Dual diagnoses of aggressive cutaneous carcinomas, although rare, may become more common in regions of high ultraviolet exposure and an ageing population. Currently, there are no guidelines for treating synchronous MCC and melanoma, however, immunotherapy with PD-1 inhibitors and anti-CTLA-4 receptor antagonists have shown therapeutic effect against these two cancers and should be considered in treatment planning.

Effectiveness of fibrin glue in skin graft survival: A systematic review and meta-analysis.

BACKGROUND: The objective of this study is to assess the current literature on the effectiveness of fibrin glue on survival of skin grafts. Fibrin glue is a possible alternative to secure skin grafts instead of traditional methods (i.e. sutures or staples). METHODS: Data Sources: MEDLINE, Scopus, Embase, Informit, CINAHL and the Cochrane Central Register of Controlled Trials, no limit on the earliest date of publication. STUDY ELIGIBILITY CRITERIA: Randomised, non-randomised controlled trials and cohort studies. PARTICIPANTS: and Interventions: Participants were patients with skin grafting/skin transplantation. The intervention was fibrin glue in any form (bovine, human pooled plasma or autologous) and comparator any form of affixing skin grafts (e.g. sutures or staples).Study Appraisal and Synthesis Methods: Studies were appraised using the Cochrane risk of bias tool and assessed for clinical heterogeneity. Effect sizes were calculated and illustrated with forest plots. RESULTS: 190 publications were narrowed to 15 relevant publications, of which eight were pooled in meta-analysis. The outcomes examined were: graft survival by percentage; graft survival reported as events; post-operative incidence of haematoma or seroma; pain reported after dressing changes via a visual analogue scale; length of stay in days (Glass's delta 2 was 0.48 95% CI 0.09, 0.97); and surgical time in minutes. Only length of stay showed a difference between groups and it favoured fibrin glue. CONCLUSIONS: While there may be benefits to the use of fibrin glue in skin graft patients, it is difficult to conclude this from the current evidence. Limitations were significant heterogeneity in outcomes measured and exclusion off non-English papers.

A case report of incidental ectopic pancreatic tissue during laparoscopic appendicectomy.

INTRODUCTION: Ectopic or heterotopic pancreas is a congenital disorder defined as abnormally located pancreatic tissue found outside the pancreatic frame. It is a rare entity that occasionally causes symptoms depending on its location. PRESENTATION OF CASE: We present the case of an incidental finding of proximal jejunal ectopic pancreas in a middle-aged woman presenting with appendicitis. DISCUSSION AND CONCLUSION: Although rare it is necessary to be aware that jejunal ectopic pancreas can lead to jejunojejunal intussusception. Although diagnostic tools are emerging, pre operative diagnosis is difficult and resection is the management of choice of the incidentally found lesion.

Prospective study of patterns of surgical management in adults with primary cutaneous melanoma at high risk of spread, in Queensland, Australia.

BACKGROUND: Knowledge of variation in diagnosis and surgery in high-risk primary melanoma patients is limited. We assessed frequency and determinants of diagnostic procedures, wide local excision (WLE) and sentinel lymph node biopsy (SLNB). METHODS: People in Queensland newly diagnosed with melanoma, clinical stage 1b or 2, were recruited prospectively. Patient information was collected from questionnaires and pathology records. Differences in surgical procedures in relation to host and tumor characteristics were assessed. RESULTS: In 787 participants, primary melanoma was diagnosed by surgical excision (74%), shave (14%), punch (12%) or incisional (1%) biopsy. General practitioners (GPs) diagnosed 80%. Diagnostic procedure differed by remoteness of residence, health sector, treating doctor's specialty and melanoma site and thickness. 766 patients had WLE, 86% by surgeons. Of 134 residual melanomas, 13 (10%) were ≤ 1 mm at diagnosis but > 1 mm at WLE, mostly after shave biopsy. SLNB was performed in 261 (33%) patients. SLNB was more common in those under 50, in remoter locations or treated by GP initially, and less common with head and neck melanoma. CONCLUSION: Diagnostic and surgical procedures for primary melanoma vary substantially and partial biopsy can influence initial tumor microstaging. Patient, tumor and doctor characteristics influence SLNB practice.

Primary cutaneous mucoepidermoid carcinoma: a case study with a review of the literature.

Mucoepidermoid carcinoma (MEC) of the skin is a rare neoplasm with few cases reported in the medical literature. We report a case of MEC of the skin in a 76-year-old man who presented with an infiltrative multinodular lesion on his right cheek. Histological description showed a multilobulated nodulocystic tumor extending throughout the dermis exhibiting glandular and squamoid differentiation. Cribiform nests of epidermoid cells contained glandular spaces with mucin. The nuclei were mildly atypical and contained scattered mitotic figures. A small focus of perineural invasion was evident within the tumor not extending beyond the deep margin with no lymphovascular invasion. There was no overlying intraepidermal carcinoma. Immunohistochemical analysis revealed staining for EMA, PanCK, and p63 whereas CK7, CK20, and CEA were negative. It is important to differentiate primary cutaneous MEC from cutaneous adenosquamous carcinoma, direct extension from an underlying primary salivary gland MEC, or metastasis of MEC from another site. We conclude that primary MEC of the skin is a low-grade neoplasm that should be differentiated from adenosquamous carcinoma. Immunohistochemical staining for p63 has proven to be helpful in differentiating primary epidermal or adnexal tumours and metastatic neoplasms to the skin.

Supportive care needs, anxiety, depression and quality of life amongst newly diagnosed patients with localised invasive cutaneous melanoma in Queensland, Australia.

OBJECTIVE: The aim of this paper is to determine levels of supportive care needs, anxiety, depression and symptoms amongst patients newly diagnosed with localised invasive primary melanoma and if these varied amongst patients who had a sentinel lymph node biopsy (SLNB). We also considered quality of life compared with general population norms. METHODS: Patients newly diagnosed with clinical stage IB-II invasive melanoma were ascertained through Queensland hospitals, specialist clinics and pathology laboratories. Validated surveys measured 46 need items (Supportive Care Needs Survey-Short Form + melanoma subscale), anxiety and depression (Hospital Anxiety and Depression Scale) and quality of life and symptoms (Functional Assessment of Cancer Therapy-Melanoma). Regression models compared outcomes according to whether or not participants had a SLNB. RESULTS: We surveyed 386 patients, 155 before and 231 after wide local excision, of whom 46% reported ≥1 moderate-level or high-level unmet need. The three highest needs were for help with fears about cancer spreading (17%), information about risk of recurrence (17%) and outcomes when spread occurred (16%). Those who had a SLNB were more likely to report a moderate or high unmet need for help with uncertainty about the future or with lymphoedema (p < 0.05). Overall, 32% of participants had anxiety and 15% had depression regardless of performance of SLNB. Melanoma-specific symptoms were worse in SLNB patients (p = 0.03). Compared with the general population, emotional well-being was lower amongst melanoma patients. CONCLUSIONS: A substantial proportion of newly diagnosed patients with localised invasive melanoma need further melanoma-specific information and support with psychological concerns. Patients who have a SLNB clear of disease may need help with symptoms after surgery.

Lower limb linear morphoea in a pregnant woman with known Graves' disease and cytomegalovirus immunoglobulin M positivity.

We report a case of linear morphoea in a 21-year-old woman with known Graves' disease who was also cytomegalovirus (CMV) IgM-positive and in her early first trimester of pregnancy. The histopathology showed hyalinisation of the dermis with perivascular superficial and deep lymphocytic infiltrates extending into the septae of the subcutis and impinging on adjacent lobules; there was also fibrosis of the subcutis. Magnetic resonance imaging showed T2 high intensity of the subcutaneous tissue and intermuscular planes of the thigh and leg. It is well known that morphoea can follow pregnancy and thyroid disease and that CMV is postulated to contribute in some patients. This case highlights a combination of risk factors for this disease that have not been reported collectively in the literature to our knowledge.

Cutaneous melanoma in the elderly.

The aim of this review was to analyze the difficulties in diagnosing and treating elderly patients with cutaneous melanoma. It focused on the main causes for late diagnosis and relatively poor prognosis in these patients. Early detection of melanoma is vital to reduce mortality in these patients and surgery is often curative. Adequate treatment of elderly patients with melanoma requires knowledge of the clinical features and histopathology of the disease, and the therapeutic options. This review also examined the main surgical procedures for primary melanoma and regional lymph node staging, and the curative and palliative procedures indicated for those elderly patients with advanced disease. It is expected that several molecular genetic factors will soon provide further prognostic information of possible benefit for elderly patients with melanoma.

Modification of lymphoscintigraphic sentinel node identification before and after excisional biopsy of primary cutaneous melanoma.

The aim of this study was to determine whether excision biopsy and primary closure of primary cutaneous melanoma modifies lymphatic drainage and accuracy of sentinel node biopsy. Thirty patients with 31 cutaneous melanomas were prospectively enrolled to undergo lymphoscintigraphy (LS) before and after excision biopsy. Tc-human serum albumin nanocolloid was first injected intradermally around the primary tumor and subsequently, after excision biopsy, adjacent to the scar. Sentinel nodes were identified by preoperative LS and the gamma-probe. Patent Blue V dye was injected intraoperatively before sentinel node biopsy. Intraoperative sentinel node identification was 100%. In 23 of 31 cases, both LSs were concordant in terms of nodal basins visualized. Two patients had a basin downstaged and six patients had a basin upstaged by the second LS. Only 50% of LS hot nodes stained blue (42 of 84). In 24 of 31 cases, the sentinel node was negative for metastases. Seven patients underwent complete lymph node dissection because of sentinel node positivity. Only one patient had metastases also to a non-sentinel node. After a median follow-up of 30 months lymph node metastases have not been observed in the eight discordant cases. This study shows that sentinel node identification and biopsy after lymphatic mapping is accurate after excision biopsy of primary cutaneous melanoma. Excision biopsy may, however, modify lymphatic drainage and a narrow excision margin should be performed if melanoma is suspected.
