Development of melanoma clinical quality indicators for the Australian melanoma clinical outcomes registry (MelCOR): A modified Delphi study.

BACKGROUND: Clinical quality registries aim to identify significant variations in care and provide anonymised feedback to institutions to improve patient outcomes. Thirty-six Australian organisations with an interest in melanoma, raised funds through three consecutive Melanoma Marches, organised by Melanoma Institute Australia, to create a national Melanoma Clinical Outcomes Registry (MelCOR). This study aimed to formally develop valid clinical quality indicators for the diagnosis and early management of cutaneous melanoma as an important step in creating the registry. METHODS: Potential clinical quality indicators were identified by examining the literature, including Australian and international melanoma guidelines, and by consulting with key melanoma and registry opinion leaders. A modified two-round Delphi survey method was used, with participants invited from relevant health professions routinely managing melanoma as well as relevant consumer organisations. RESULTS: Nineteen participants completed at least one round of the Delphi process. 12 of 13 proposed clinical quality indictors met the validity criteria. The clinical quality indicators included acceptable biopsy method, appropriate excision margins, standardised pathology reporting, indications for sentinel lymph node biopsy, and involvement of multidisciplinary care and referrals. CONCLUSION: This study provides a multi-stakeholder consensus for important clinical quality indicators that define optimal practice that will now be used in the Australian Melanoma Clinical Outcomes Registry (MelCOR).

The management of dysplastic naevi: a survey of Australian dermatologists.

BACKGROUND/OBJECTIVES: The management of dysplastic naevi based on histopathological grading is a contentious issue. Comprehensive management guidelines are lacking and the approach taken varies between clinicians. The authors sought to understand how Australian dermatologists approach the management of biopsy-proven dysplastic naevi, and the impact of grading of dysplasia upon this management. METHODS: In total, 547 Fellows of the Australasian College of Dermatologists were surveyed and 218 responses were collected (40% response rate). RESULTS: Although all dermatologists surveyed would re-excise an incompletely removed severely dysplastic naevus, opinion was divided over whether to treat such a lesion as an in situ melanoma or a dysplastic naevus, with 55% of respondents using a 5-mm margin and the remainder opting for narrow margin re-excision. When the same lesion was reported to be clear of margins by 1 mm after biopsy and the clinical suspicion for melanoma was high, 44% would re-excise with a 5-mm margin. CONCLUSIONS: The approach of Australian dermatologists to the management of dysplastic naevi varies between clinicians, reflecting the problems raised by the validity of histopathological grading.

Unstable solar lentigo: A defined separate entity.

An unstable solar lentigo is a solar lentigo with areas of melanocytic hyperplasia not extending past the margin of the lesion. They are discrete, macular, pigmented lesions arising on sun-damaged skin and a subset of typical solar lentigos. Clinically they differ from usual solar lentigines in often being solitary or larger and darker than adjacent solar lentigines. These lesions are of clinical importance as they can arise in close proximity to lentigo maligna and in a single lesion there can be demonstrated changes of solar lentigo, unstable solar lentigo and lentigo maligna. These observations led us to conjecture that unstable solar lentigos could be a precursor lesion to lentigo maligna. In this article we examine the possibility that lentigo maligna can arise within a solar lentigo through an intermediate lesion, the unstable solar lentigo. We propose that the histopathological recognition of this entity will allow for future research into its behaviour and thus management. We review difficulties in the diagnosis of single cell predominant melanocytic proliferations and the concept of unstable lentigo in view of the literature and clinical experience supporting the proposal of its recognition as a separate entity.

Tele-Derm National: A decade of teledermatology in rural and remote Australia.

OBJECTIVE: To identify the current scope of Tele-Derm, the types of dermatological complaints experienced in the rural primary care setting, and to assess the quality of patient clinical information provided to the consultant dermatologist. DESIGN: Retrospective case analysis. SETTING: Tele-Derm National is an initiative of the Australian College of Rural and Remote Medicine and has been providing online educational and consultational services in dermatology to doctors Australia-wide for over a decade. PARTICIPANTS: Patient cases that were submitted to Tele-Derm for specialist dermatologist advice. INTERVENTIONS: Audit of submitted cases. MAIN OUTCOME MEASURES: The types of patient presentations and reason for submission for specialist opinion were analysed. The quality of clinical information provided was also evaluated. RESULTS: A total of 406 cases submitted over 2012-2013 were analysed. Most patients were from the outpatient setting with 'rash' or dermatitis (66%). Almost one-third of patients were paediatric cases. The average time from submission to dermatologist reply was 5.5 hours. Clinical photos were provided in 83% of cases and 73% of these were assessed as being of good quality. Management advice was provided in 77% of cases, of which reference to the case-based learning modules on Tele-Derm was made in 21% of cases. Patient outcome was largely unknown (83%). CONCLUSION: This study identified some of the common dermatological complaints presenting to rural and remote primary care doctors in Australia. The unique addition of professional development in Tele-Derm can be used as an adjunct to advice provided to the rural doctors seeking advice for patient management.

Assessment of subcomponents of executive functioning in ecologically valid settings: the goal processing scale.

OBJECTIVES: To validate a new functional assessment tool, the Goal Processing Scale (GPS), and to apply it for testing for sources of dysfunction in patients with acquired brain injury. Determining which component processes of executive functioning underlie poor performance in complex, low-structure settings would be valuable for the assessment of deficits and for evaluating the effectiveness of treatments. PARTICIPANTS: Nineteen individuals with chronic acquired brain injury (mean age = 41.4 years; chronicity: 6 months to 39 years). MAIN MEASURES: Two functional assessment tasks: (1) GPS, which evaluates functional performance in the context of achieving a goal in a "real-world" setting, with rating scales measuring overall performance and 8 subdomains of executive functioning; (2) Multiple Errands Test, an unstructured assessment of ability to adhere to rules and complete multiple "real-world" tasks in a short time; and (3) a neuropsychological battery. RESULTS: Intraclass correlation coefficients for 2 independent raters ranged from 0.75 to 0.98 for the GPS overall composite score and the subdomain scores. Performance on GPS overall and several subdomain scores correlated with performance on the Multiple Errands Test. Working memory and learning/memory neuropsychological measures predicted functional performance as measured using the GPS. DISCUSSION: The GPS shows high interrater reliability, suggesting convergent validity with an established functional performance measure, and produces useful information regarding strengths and weaknesses in different subdomains of executive functioning. Working memory and learning/memory appear to be key determinants of goal-directed functioning for these individuals with brain injury.

Patch testing for allergic contact dermatitis to cigarettes: smoked/unsmoked components and formaldehyde factors.

A patient with hand dermatitis reported that switching her smoking hand resulted in reduced symptoms. When allergy to cigarettes is suspected the literature supports standard allergy testing as well as testing the individual components of cigarettes. Initial standard patch testing revealed an allergy to formaldehyde and the formaldehyde releasing agent, quaternium-15. The patient did not react to her usual roll-your-own cigarette components but reacted to the smoked filter paper of a particular brand of cigarette she frequently borrowed from a friend. Possible explanations include either a variation of ingredients between cigarettes that alters the formaldehyde concentration or another unidentified allergen in the branded cigarette causing allergic contact dermatitis.

Dermatological reactions to ophthalmic preparations: more than meets the eye.

Ophthalmic preparations are commonly used medications that have been implicated in causing a variety of dermatological reactions. These reactions include toxic epidermal necrolysis, anaphylaxis, fixed drug eruption, lichenoid drug reaction and local and systemic contact dermatitis. This article reviews the dermatological and systemic reactions associated with ophthalmic preparation use and highlights the need for a thorough medication history to be done for all patients presenting with a suspected drug reaction.

Guide to shave procedures in general practice.

BACKGROUND: General practitioners manage a significant proportion of inflammatory and neoplastic skin conditions on a daily basis. Various surgical techniques can be employed to aid in diagnosis, including punch biopsies, shave biopsy, shave excision, incisional biopsy, curettage and formal excision with closure. Requiring minimal equipment, shave procedures are quick to perform, produce good cosmetic outcomes and minimise costs. OBJECTIVE: Our aim is to discuss shave procedures in detail and highlight the difference between shave biopsies and shave excisions, as well as the role they each have in diagnosing an array of benign, inflammatory and malignant skin conditions, including melanocytic lesions. DISCUSSION: Shave procedures performed on suitable lesions by trained practitioners can be used for sampling or removing suspect lesions. Where the intent is complete removal, margin involvement is rare given good lesion selection and technique.

Toxic epidermal necrolysis caused by over the counter eyedrops.

We present a case of a 15-year-old boy who developed toxic epidermal necrolysis (TEN) from sulfacetamide eyedrops. He presented with conjunctival injection and an erythematous rash that rapidly progressed to epidermal necrosis of over 30% of his body. A skin biopsy revealed an acute lichenoid reaction pattern consistent with TEN. After 22 days in hospital, he was left with significant scarring to his eyes, mouth and anogenital areas. An extensive search for an infective aetiology was negative. Previously exposed to bactrim tablets, he used Bleph-10 eyedrops 3 days before admission to hospital. The patient had a strong family history of sulphur allergy. The onset of TEN after topical administration of medication has been reported rarely in the literature. This case highlights the need for a thorough medication history that includes topical preparations.

Early melanoma with halo eczema (Meyerson's phenomenon).

We present a case of a 49-year-old man who presented with a solitary atypical pigmented lesion with a surrounding halo of dermatitis. Dermoscopy showed a pigment network at the periphery with areas of scar-like depigmentation, negative pigment network and erythema. The lesion was treated preoperatively with a potent topical corticosteroid resulting in a reduction of inflammation. Histology showed an early Clark level 1 melanoma arising within a severely dysplastic compound melanocytic naevus. There was an adjacent perivascular chronic inflammatory cell infiltrate with occasional eosinophils. Minimal, though definite spongiosis with parakeratosis was also present. The scar was subsequently re-excised achieving appropriate excision margins for melanoma in situ. Six months later, there was recurrence of dermatitis at the scar with no evidence of recurrent melanoma. To our knowledge, melanoma with Meyerson phenomenon has not been reported in the literature. This case highlights that all lesions should be evaluated on clinical and dermoscopic grounds regardless of the presence or absence of eczema. Our case adds yet another entity that may display Meyerson phenomenon and consequently a halo of eczema cannot be considered a reassuring sign when evaluating melanocytic lesions.

A guide to curettage and cautery in the management of skin lesions.

BACKGROUND: Curettage and cautery is a procedure used for treatment of low-risk skin malignancies and pre-cancerous lesions. Given good lesion selection and technique, high cure rates and good cosmesis are routine for this quick, simple and cost-effective operation. OBJECTIVE: The purpose of this article is to review and summarise the steps in managing carefully selected cutaneous lesions with curettage and cautery. DISCUSSION: This article will address lesion selection, technique, efficacy, complications and how to incorporate curettage into daily practice.

Pathologically oriented descriptive study of male genital circumcisions across medical and surgical specialties.

BACKGROUND: Circumcision is one of the most frequently performed procedure by clinicians, yet its role and indication in clinical practice lacks consensus and remains unclear. We sought to evaluate a collection of male circumcisions to determine the range of indications, histopathological diagnoses, and type of clinicians associated with circumcision. METHODS: We performed a retrospective descriptive cohort study of male patients who received a circumcision reported by one major dermatopathology laboratory between January 2017 and December 2018. Data were extracted from the histological report of the pathologist for each case. Patient age, type of clinician, clinical notes, and histopathological diagnosis were evaluated. RESULTS: "/> A total of 406 circumcisions were identified. The median age for circumcision was 36 (IQR 16-61). Boys less than 18 years of age made up 24% (98/406). Histological diagnoses included normal (43/406, 11%), nonspecific inflammation (82/406, 20%), inflammatory conditions (264/406, 65%), infections (9/406, 2.2%), benign neoplasms (5/406, 1.0%), and scar tissue (3/406, 0.7%). The most common diagnosis was balanitis xerotica obliterans (226/406, 56%). Rarely, genital infections and neoplastic lesions were identified. Circumcisions were performed by urologists (289/406, 71.2%), general practitioners (76/406, 18.7%), general surgeons (32/406, 8%), pediatric surgeons (5/406, 1%), and dermatologists (4/406, 1%). The main indications for circumcision were phimosis (110/202, 54%), suspected lichen sclerosus (28/202, 14%), and balanitis (15/202, 7%). CONCLUSION: Circumcision was performed for a broad range of genital dermatoses across various medical and surgical specialties. Few studies have described these observations. We discuss the common pathological conditions leading to circumcision and its role in diagnosis and treatment.

Recognising skin manifestations of rheumatological disease.

BACKGROUND: An understanding of skin conditions associated with rheumatic diseases ensures accurate diagnosis and management. Cutaneous manifestations of rheumatological disease are legion. OBJECTIVE: The aim of this article is to increase clinician familiarity with the dermatological manifestations of rheumatic conditions to enable accurate diagnosis and effective management. DISCUSSION: This article will address the skin manifestations of lupus erythematosus, rheumatoid arthritis, psoriatic arthritis, dermatomyositis and scleroderma, including their implications in diagnosis, prognosis and treatment.

Genital premalignant and malignant diseases: a retrospective study of male genital skin biopsies.

BACKGROUND: Genital skin malignancies are a rare entity encountered by clinicians that may result in significant morbidity and mortality. Lack of familiarity or expertise in this area among clinicians can delay appropriate management of these conditions and may result in disease progression. METHODS: We performed a retrospective descriptive cohort study of male patients who received a genital skin biopsy reported by one major dermatopathology laboratory between January 2017 and December 2018 with a histological diagnosis of a premalignant or malignant condition. Patient age, type of clinician, clinical notes, genital site, type of biopsy performed, and histopathological diagnosis were evaluated. RESULTS: Of the 1525 male genital skin biopsies available for analysis, 5% (74/1525) were premalignant or malignant diseases. These included penile intraepithelial neoplasia (PeIN) (42/74, 57%), followed by invasive squamous cell carcinoma (SCC) (11/74, 15%), Bowenoid papulosis (BP) (9/74, 12%), basal cell carcinoma (8/74, 11%), malignant melanoma (2/74, 2.7%), extramammary Paget's (1/74, 1.4%), and metastatic cutaneous deposits (1/74, 1.4%). PeIN and BP most commonly affected the penile shaft ([18/42] 43% and [4/9] 44%, respectively), invasive SCCs most commonly affected the glans penis (4/11, 36%), and all BCCs (8/8, 100%) were located on the scrotum. Invasive SCCs were most biopsied by urologists, BP was most biopsied by dermatologists, and PeINs and BCCs were most biopsied by general practitioners. CONCLUSIONS: A variety of genital malignancy types were found in males. A greater understanding of male genital premalignant and malignant conditions may help guide education and further research in this area.
