Managing atopic dermatitis with systemic therapies in adults and adolescents: An Australian/New Zealand narrative

Publisher: Wiley

Date: 16-09-2019

DOI: 10.1111/AJD.13141

Abstract: With the rapid development of new, targeted therapies for the treatment of moderate/severe atopic dermatitis, it is opportune to review the available conventional systemic agents. We assess the published evidence for systemic therapies for atopic dermatitis and amalgamate this with real-world experience. Discussions are centred on when systemic therapy should be considered, which drug(s), what dose, how to sequence or combine these therapies, how long they should be continued for and what is considered success.

Acute Severe Hepatitis of Unknown Etiology in Children: A Mini-Review

Publisher: MDPI AG

Date: 27-05-2022

DOI: 10.20944/PREPRINTS202205.0370.V1

Abstract: The emergence of acute, severe non hepA& ndash E hepatitis of unknown etiology (ASHUE) has attracted global concern owing to the very young age of the patients and its unknown etiology. Although this condition has been linked to several possible causes, including viral infection, drugs, and/or toxin exposure, the exact cause remains unknown this makes treatment recommendations very difficult. In this review, we summarize recent updates on the clinical manifestations, complemented with laboratory results, case numbers with the global distribution and other epidemiological characteristics, and the possible etiologies. We also provide the proposed actions that could be undertaken to control and prevent further spread of this hepatitis. Since many etiological and pathological aspects of the acute non hepA& ndash E hepatitis remain unclear, further research is needed to minimize the severe impact of this disease.

Discoid (nummular) eczema in the paediatric setting - An Australian/New Zealand narrative.

Publisher: Wiley

Date: 04-09-2022

DOI: 10.1111/AJD.13915

Abstract: Discoid (nummular) eczema is a common and distinctive eczema variant, which has not been studied in depth. Although the principles of management are similar to that of classic atopic dermatitis, distinctions are made due to its unique presentation and persistent clinical course in children. Australian and New Zealand dermatologists with an interest in paediatric eczema developed a consensus narrative to assist clinicians in diagnosing and treating this subtype of eczema. Identifying triggers, potent topical corticosteroids under occlusion, skin barrier support and management of pruritus are first-line therapies, however, many eventually require systemic immunomodulatory agents.

Psoriasis and cancer. An Australian/New Zealand narrative

Publisher: Wiley

Date: 10-07-2018

DOI: 10.1111/AJD.12889

Abstract: Patients with psoriasis have an increased risk of cancer, which may be due to impaired immune surveillance, immune modulatory treatments, chronic inflammation and/or co-risk factors such as obesity. The increase in treatment-independent solid cancers, including urinary/bladder cancers, oropharynx/larynx, liver/gallbladder and colon/rectal cancers, seem to be linked to alcohol and smoking. Lung cancer and nonmelanoma skin cancer are also increased in patients with psoriasis. The risk of nonmelanoma skin cancer increases with age and severity of psoriasis. It is also higher in men, particularly for squamous cell carcinoma, which may reflect previous exposure to PUVA and/or ciclosporin. The risk of cutaneous T-cell lymphoma is substantially higher in patients with moderate-to-severe psoriasis. Biologic therapies are independently associated with a slight increase risk of cancer, but this is less than ciclosporin, with the risk confounded by disease severity and other co-risk factors. The risk of cancer from low-dose methotrexate is likely minimal. In contrast, acitretin is likely protective against a variety of solid and haematological malignancies. The data on small molecule therapies such as apremilast are too immature for comment, although no signal has yet been identified. The decision whether to stop psoriasis immune modulatory treatments following a diagnosis of cancer, and when to resume, needs to be considered in the context of the patients' specific cancer. However, there is no absolute need to stop any treatment other than possibly ciclosporin, unless there is a concern over an increased risk of serious infection or drug-drug interaction with cancer-directed therapies, including radiotherapy.

Management of chronic hand and foot eczema. An Australia/New Zealand Clinical narrative

Publisher: Wiley

Date: 10-08-2020

DOI: 10.1111/AJD.13418

Abstract: Chronic hand/foot eczemas are common, but treatment is often challenging, with widespread dissatisfaction over current available options. Detailed history is important, particularly with regard to potential exposure to irritants and allergens. Patch testing should be regarded as a standard investigation. In idual treatment outcomes and targets, including systemic therapy, should be discussed early with patients, restoring function being the primary goal, with clearing the skin a secondary outcome. Each new treatment, where appropriate, should be considered additive or overlapping to any previous therapy. Management extends beyond mere pharmacological or physical treatment, and requires an encompassing approach including removal or avoidance of causative factors, behavioural changes and social support. To date, there is little evidence to guide sequences or combinations of therapies. Moderately symptomatic patients (e.g. DLQI ≥ 10) should be started on a potent/super‐potent topical corticosteroid applied once or twice per day for 4 weeks, with tapering to twice weekly application. If response is inadequate, consider phototherapy, and then a 12‐week trial of a retinoid (alitretinoin or acitretin). Second line systemic treatments include methotrexate, ciclosporin and azathioprine. For patients presenting with severe symptomatic disease (DLQI ≥ 15), consider predniso(lo)ne 0.5–1.0 mg/kg/day (or ciclosporin 3 – 5 mg/kg/day) for 4–6 weeks with tapering, and then treating as for moderate disease as above. In non‐responders, botulinum toxin and/or iontophoresis, if associated with hyperhidrosis, may sometimes help. Some patients only respond to long‐term systemic corticosteroids. The data on sequencing of newer agents, such as dupilumab or JAK inhibitors, are immature.

Acceptance and willingness to purchase a hypothetical COVID-19 vaccine in a region under Shariah law: A cross-sectional study in Aceh, Indonesia

Publisher: Narra T

Date: 08-2022

DOI: 10.52225/NARRA.V2I2.85

Abstract: Vaccines are urgently needed to control the coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to determine the acceptance of and willingness to purchase a hypothetical COVID-19 vaccine in the general population of Aceh, a holistic Shariah law implementation province in Indonesia. An online cross-sectional study was conducted using a quota s ling technique between 1 to 24 September 2021. To determine hypothetical vaccine acceptance, respondents were asked if they were willing to accept vaccines with combinations of either 50% or 95% effectiveness and either 5% or 20% risk of adverse effects. Willingness to purchase was assessed by asking whether the participants would pay for such vaccines at certain price points. Logistic regression analysis was used to assess the associated determinants. Out of 377 respondents included in the final analysis, 86.5% were willing to accept a COVID-19 vaccine with 95% effectiveness and 5% adverse effects. The acceptance rate dropped to 45.1% if the risk of adverse effects was 20%. Vaccines with 50% effectiveness and 5% adverse effects were acceptable to 42.2% but the acceptance went down to 17.2% if the risk of adverse effects increased to 20%. Multivariate analysis found that men were twice as likely to accept a vaccine with 95% effectiveness and 5% adverse effects compared to females (aOR: 2.01 95% CI 1.05–3.86). We found that 156/377 (41.3%) of respondents were willing to purchase a COVID-19 vaccine and of these participants 71.1% were willing to pay between Indonesian Rupiah (IDR) 50,000–150,000 (US$ 3.33–10.00). In conclusion, the acceptance rate of a hypothetical COVID-19 vaccine varied based on effectiveness and the risk of adverse effects.

In situ and invasive melanoma in a high-risk, New Zealand, population: A population-based study

Publisher: Wiley

Date: 26-07-2019

DOI: 10.1111/AJD.12884

Abstract: Few population-based studies assess both invasive and in situ melanoma. We document all patients with a first biopsied melanoma in a general population in New Zealand (NZ). All residents in a defined area of New Zealand with a biopsy showing a new primary invasive or in situ melanoma from 2010 to 2012 were identified, 974 patients analysis used multivariate methods. Age-standardised incidence rates were 34.3 in females (F) and 41.4 in males (M) for invasive, 20.9 F and 27.6 M for in situ, and 55.2 F and 69.0 M for total melanoma. More in situ melanoma occurred in older patients and on the head and neck. Geometric mean Breslow thickness for invasive was 0.78 mm F and 0.85 mm M, with thicker lesions at ages over 60 and on the lower limb there was no significant relationship with sex, distance from care or social deprivation assessed from residential address. Nodular melanomas (15%) were more frequent in older and male patients, and on the limbs, and were thicker. The estimated cumulative risk for melanoma is 4.4% F and 4.6% M by age 70. The body site distribution and sex differences were consistent with sun exposure patterns. Estimated incidence of melanoma in New Zealand in 2018 is 2500 invasive and 1700 in situ cases. Assessing both in situ and invasive melanoma expands the clinical picture, better estimating health care demand and costs. Results suggest that in situ disease is a more slowly growing lesion than the early phase of invasive disease. The features of thicker or nodular melanoma show priorities for prevention and early detection.

Very low‐dose isotretinoin in mild to moderate papulopustular rosacea; a retrospective review of 52 patients

Publisher: Wiley

Date: 20-07-2018

DOI: 10.1111/AJD.12522

Abstract: Rosacea is a chronic inflammatory disorder that affects up to 10% of the population. Standard treatments include topical azelaic acid and metronidazole or systemic tetracyclines. Isotretinoin has generally been restricted to severe disease, often at a dose of 0.5-1.0 mg/kg/day. Retrospective review of open-label isotretinoin (initial dose 20 mg/day, with dose adjustments according to response), in patients with mild to moderate papulopustular rosacea. Altogether 52 patients (33 women), mean age 48 years (range 18-86) were treated with isotretinoin over a 5-year period. All patients were commenced on 20-mg isotretinoin/day which was reduced to 10-20 mg once to five times a week (equivalent to 5 mg/day) in 67%, but increased in 15% (who all had additional acne) to 30-40 mg/day. In terms of dose/kg/day, 29% received ≤ 0.1 mg/kg/day, 46% received 0.11-0.25 mg/kg/day and 10% received > 0.5 mg/kg/day. Treatment was continued for 57 weeks (range 9-223). Six patients (12%) did not attend follow up. Of the remainder, in 91% (42/46) the rosacea had cleared or was excellent. One patient stopped isotretinoin because of its adverse effects. Two-fifths (44%) suffered no adverse effect. The most common side-effect was cheilitis in half (52%), which was mild in all but one patient. Very low-dose isotretinoin (e.g., 10-20 mg once to five times a week, equivalent to 5 mg/day) is an effective treatment for mild to moderate papulopustular rosacea and is well tolerated.

Consensus statement for the treatment of infantile haemangiomas with propranolol.

Publisher: Wiley

Date: 03-2017

DOI: 10.1111/AJD.12600

Abstract: Although most infantile haemangiomas do not require treatment due to a natural history of spontaneous involution, some require early intervention. The Australasian Vascular Anomalies Network and the Australasian Paediatric Dermatology Network have developed a consensus statement for the treatment of infantile haemangiomas with oral propranolol. Infants with haemangiomas that are life threatening, at risk of ulceration, or at risk of causing a significant functional impairment, psychological impact or physical deformity should be treated early with oral propranolol. Oral propranolol is safe and effective and in most healthy infants oral propranolol can be started in an outpatient setting.

Virtual lesion clinic – Evaluation of a teledermatology triage system for referrals for suspected melanoma

Publisher: Wiley

Date: 27-12-2021

DOI: 10.1111/AJD.13777

Abstract: The Virtual Lesion Clinic (VLC) of Waitematā District Health Board (WDHB) improves melanoma assessment and treatment using teledermatology. The VLC is reserved for pigmented lesions referred as suspected melanoma from primary care but indeterminate at the initial triage. To assess the efficacy of the VLC diagnosis of melanoma. A retrospective audit of suspected melanoma referrals (1 January 2012 to 31 December 2016) was conducted. Lesions were referred to the VLC if diagnostic uncertainty remained at the initial triage. VLC patients attended MoleMap imaging centres, a dermatologist reviewed history and images remotely and suggested a diagnosis and management plan. Post VLC provisional diagnosis of melanoma, all lesions subsequently excised were reviewed. A positive predictive value (PPV) was calculated using concordance between VLC diagnosis of melanoma and histopathological diagnosis of melanoma. Number needed to excise (NNE) for melanoma was derived, as well as an invasive to in‐situ melanoma ratio (IM:MIS) and false negative rate (FNR). The VLC received 1874 referrals for 3546 lesions during the 5‐year study period. Six hundred and seventy‐nine lesions were recommended excision/biopsy or specialist face‐to‐face assessment, and 504 lesions were subsequently excised. The PPV was 62%, NNE 1.62 and IM:MIS 0.76 for lesions suspected to be melanoma at VLC assessment. The VLC had a melanoma‐specific FNR of 7%. The VLC is effective in early diagnosis of melanoma with a high positive predictive value, low number needed to excise and low false negative rate amongst lesions referred as suspected melanoma.

A baseline patch test series for New Zealand.

Publisher: Wiley

Date: 22-07-2021

DOI: 10.1111/AJD.13673

Abstract: Patch testing is the gold standard diagnostic test for allergic contact dermatitis and needs to be relevant to the region and the population being tested. The aim of this study was to develop a specific New Zealand baseline series (NZBS). We performed a retrospective case note review of patients attending four regional patch test centres between 2008 and 2020. Demographic and diagnostic information was collected for each patient along with results of patch testing. Using the results of this review, a group of 11 dermatologists with an interest in contact dermatitis agreed on a core group of allergens for inclusion in an NZBS, based on the frequency of positive reactions and allergens of interest. The remaining potential allergens were ranked by each dermatologist using an online questionnaire, with inclusion in the final NZBS by consensus. Results from 2402 patients (67% female, mean age 44 years) from Auckland, Wellington, Palmerston North and Christchurch were collated. The 10 most frequent positive (relevant and non-relevant) allergens were nickel sulfate (22.0%), fragrance mix I (8.6%), cobalt chloride (7.3%), Myroxylon pereirae (5.6%), colophonium (5.1%), p-phenylenediamine (4.9%), methylisothiazolinone/methylchloroisothiazolinone (4.1%), fragrance mix II (3.9%), potassium dichromate (3.5%) and methylisothiazolinone (3.4%). Based on these results, a core series of 30 allergens was developed, with an additional 30 allergens added to form the extended series (total 60 allergens). The baseline series of patch test allergens for routine use in New Zealand (NZBS) is based on national patch test data and expert consensus.

Psoriasis in those planning a family, pregnant or breast-feeding. The Australasian Psoriasis Collaboration.

Publisher: Wiley

Date: 23-05-2017

DOI: 10.1111/AJD.12641

Abstract: The Australasian Psoriasis Collaboration has reviewed the evidence for managing moderate to severe psoriasis in those who are pregnant or are breast-feeding, or planning a family. The severity of the psoriasis, associated comorbidities and specific anti-psoriasis treatment, along with other exposures, can have a deleterious effect on pregnancy outcomes. Psoriasis itself increases the risk of preterm and low birthweight babies, along with spontaneous and induced abortions, but no specific birth defects have been otherwise demonstrated. The baseline risk for a live born baby to have a major birth defect is 3%, and significant neuro-developmental problem is 5%. In Australia, pregnant women with psoriasis are more likely to be overweight or obese, depressed, or smoke in their first trimester, and are also less likely to take prenatal vitamins or supplements. Preconception counselling to improve maternal, pregnancy and baby health is therefore strongly encouraged. The topical and systemic therapies commonly used in psoriasis are each discussed separately, with regards to pregnancy exposure, breast-feeding and effects on male fertility and mutagenicity. The systemic therapies included are acitretin, adalimumab, apremilast, certolizumab, ciclosporin, etanercept, infliximab, ixekizumab, methotrexate, NBUVB, prednisone, PUVA, secukinumab and ustekinumab. The topical therapies include dithranol (anthralin), calcipotriol, coal tar, corticosteroids (weak, potent and super-potent), moisturisers, salicylic acid, tacrolimus, and tazarotene. As a general recommendation, effective drugs that have been widely used for years are preferable to newer alternatives with less foetal safety data. It is equally important to evaluate the risks of not treating, as severe untreated disease may negatively impact both mother and the foetus.

Dermoscopic 'Chaos and Clues' in the diagnosis of melanoma in situ.

DOI: 10.1111/AJD.12740

Abstract: To describe the dermoscopic features of melanoma in situ using the Chaos and Clues method. Histologically proven primary melanoma in situ (MIS) diagnosed through a specialist teledermoscopy clinic were reviewed by three dermatologists. By consensus they agreed on the global dermoscopic pattern, colours, presence of chaos (asymmetry of colour and structure and more than one pattern), and each of the nine clues described for malignancy. One hundred MIS in 92 patients of European ethnicity (45 males) were assessed. Mean age was 67.3 years (range 20-95). The mean dimensions of the lesions were 11.1 × 12.0 mm (range 2.5-31.3 × 2.3-32.3 mm). Using pattern analysis, 82% of the lesions had three or more patterns (multicomponent) and the rest had 2 patterns. Colours included light brown (100%), dark brown (98%) and grey (75%). All MIS demonstrated chaos. The most prevalent clues were thick lines (88%), eccentric structureless areas (88%), and grey or blue structures (75%). Dermoscopy can be very helpful in the early diagnosis of melanoma and MIS. The Chaos and Clues method is simple to use. Its unambiguous descriptors can be successfully used to describe MIS. The presence of chaos and clues to malignancy (including thick lines, eccentric structureless areas, and blue/grey structures) should raise a red flag and lead to referral or excision.

Abstract: Since it was first approved for use in 1982, isotretinoin has revolutionized the management of acne vulgaris. Despite almost four decades of widespread use, uncertainty still exists regarding the manner in which it is best prescribed. In this review, we provide an update on the pharmacokinetics, mechanism of action, contraindications, interactions, and appropriate dosing schedule of isotretinoin in the treatment of acne. We also discuss the safety of performing concurrent dermatological procedures in patients taking isotretinoin.

Abstract: Infectious threats to humans are continuously emerging. The 2022 worldwide monkeypox outbreak is the latest of these threats with the virus rapidly spreading to 106 countries by the end of September 2022. The burden of the ongoing monkeypox outbreak is manifested by 68,000 cumulative confirmed cases and 26 deaths. Although monkeypox is usually a self-limited disease, patients can suffer from extremely painful skin lesions and complications can occur with reported mortalities. The antigenic similarity between the smallpox virus (variola virus) and monkeypox virus can be utilized to prevent monkeypox using smallpox vaccines treatment is also based on antivirals initially designed to treat smallpox. However, further studies are needed to fully decipher the immune response to monkeypox virus and the immune evasion mechanisms. In this review we provide an up-to-date discussion of the current state of knowledge regarding monkeypox virus with a special focus on innate immune response, immune evasion mechanisms and vaccination against the virus.

Abstract: The recent monkeypox or mpox outbreak has been a global concern. The present study evaluated the global research outputs, research trends, and topics of published research on monkeypox using a bibliometric approach. The Scopus database was searched for terms associated with "monkeypox" or "monkey pox" up until 19 November 2022. Maps and bibliometric indicators of the retrieved documents were shown and analyzed. A total of 1,422 documents were obtained from Scopus. Other than monkeypox, the most commonly used terms included epidemic, disease outbreaks, smallpox vaccine, and orthopoxvirus. In total, 90.3% of the documents were published between 2002 and 2022. The United States, the United Kingdom, and India were the top three countries in terms of productivity. Most of the institutions were from the United States. The International Journal of Surgery, the Journal of Medical Virology, and the Travel Medicine and Infectious Disease are some of the top journals currently publishing research on monkeypox. Tecovirimat, coronavirus disease 2019 (COVID-19), homosexuality, and pandemic are emerging topics related to monkeypox.

SARS‐CoV‐2 (COVID‐19) vaccination in dermatology patients on immunomodulatory and biologic agents: Recommendations from the Australasian Medical Dermatology Group

Publisher: Wiley

Date: 30-03-2021

DOI: 10.1111/AJD.13593

Abstract: As the phase III COVID‐19 vaccine trials excluded patients on immunosuppressive treatments, or patients with significant autoimmunity, the Australasian Medical Dermatology Group make the following preliminary recommendations around COVID‐19 vaccination in dermatology patients on immunomodulatory and/or biologic agents. Vaccination against COVID‐19 is strongly encouraged for all patients on immunomodulatory drugs and/or biologic agents. There are currently insufficient data to recommend one COVID‐19 vaccine or vaccine type (mRNA, recombinant, inactivated virus) over another. No specific additional risk in patients on immunomodulatory or biologic therapies has so far been identified. Data on vaccine efficacy in patients on immunomodulatory or biologic therapies are missing, so standard vaccination protocols are recommended until otherwise advised.

Nonpharmaceutical interventions reduce the incidence and mortality of COVID‐19: A study based on the survey from the International COVID‐19 Research Network (ICRN)

Publisher: Wiley

Date: 30-01-2023

DOI: 10.1002/JMV.28354

Abstract: The recently emerged novel coronavirus, “severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2),” caused a highly contagious disease called coronavirus disease 2019 (COVID‐19). It has severely damaged the world's most developed countries and has turned into a major threat for low‐ and middle‐income countries. Since its emergence in late 2019, medical interventions have been substantial, and most countries relied on public health measures collectively known as nonpharmaceutical interventions (NPIs). We aimed to centralize the accumulative knowledge of NPIs against COVID‐19 for each country under one worldwide consortium. International COVID‐19 Research Network collaborators developed a cross‐sectional online survey to assess the implications of NPIs and sanitary supply on the incidence and mortality of COVID‐19. The survey was conducted between January 1 and February 1, 2021, and participants from 92 countries/territories completed it. The association between NPIs, sanitation supplies, and incidence and mortality were examined by multivariate regression, with the log‐transformed value of population as an offset value. The majority of countries/territories applied several preventive strategies, including social distancing (100.0%), quarantine (100.0%), isolation (98.9%), and school closure (97.8%). In idual‐level preventive measures such as personal hygiene (100.0%) and wearing facial masks (94.6% at hospitals 93.5% at mass transportation 91.3% in mass gathering facilities) were also frequently applied. Quarantine at a designated place was negatively associated with incidence and mortality compared to home quarantine. Isolation at a designated place was also associated with reduced mortality compared to home isolation. Recommendations to use sanitizer for personal hygiene reduced incidence compared to the recommendation to use soap. Deprivation of masks was associated with increased incidence. Higher incidence and mortality were found in countries/territories with higher economic levels. Mask deprivation was pervasive regardless of economic level. NPIs against COVID‐19 such as using sanitizer, quarantine, and isolation can decrease the incidence and mortality of COVID‐19.

Psoriasis and infection. A clinical practice narrative

Publisher: Wiley

Date: 05-08-2018

DOI: 10.1111/AJD.12895

Abstract: The Australasian Psoriasis Collaboration has developed a clinical practice narrative with respect to the relationship between psoriasis, its treatment and infection. The cutaneous microbiome of patients with psoriasis is different to those without psoriasis, although the significance of this is unclear. Whilst a wide range of microorganisms has been associated with psoriasis (including β-haemolytic streptococci, Staphylococcus aureus, Porphyromonas gingivalis, Candida albicans, Chlamydia psittaci, human immunodeficiency virus and hepatitis C virus), there is limited evidence that antimicrobial therapy is of direct benefit in preventing flares of psoriasis. Psoriasis is independently associated with an increased risk of serious infection, but the absolute risk is low. The risk of serious infections is further increased with immune-modulatory treatments. The decision whether to, and when to, stop or resume immune-modulatory treatment after a serious infection has occurred depends on risk assessment for that patient, taking into account the infection being treated, the risk of recurrent infection, any interventions that can modify the risk and the need for psoriasis control. Live vaccines (e.g. MMR, varicella, zoster and yellow fever) are generally contraindicated in patients with psoriasis on immune-modulatory agents, but this depends on the degree of immune suppression and in idual risk factors. Wound healing in psoriasis is normal. Treatment with infliximab, adalimumab, etanercept, methotrexate and ciclosporin can safely be continued through low-risk surgical procedures. For moderate- and high-risk surgeries, a case-by-case approach should be taken based on the patient's in idual risk factors and comorbidities.

Bullous pemphigoid: Its incidence, mortality and clinical outcome in New Zealand.

Publisher: Wiley

Date: 24-03-2022

DOI: 10.1111/AJD.13822

Abstract: Bullous pemphigoid (BP) is an uncommon autoimmune bullous disorder, with significant morbidity and mortality. Mortality may be as high as 23.5% in the first year after diagnosis. Clear epidemiologic data across Australasia are lacking. A retrospective, multi-centred cohort study was designed to determine the incidence and mortality of bullous pemphigoid in New Zealand. Data from all histopathologically diagnosed patients with bullous pemphigoid between 2009 and 2015 from the Auckland region were obtained. Demographics, clinical characteristics and outcome 3 years from diagnosis (until 31 December 2018) were collected. Demographic data were compared against a denominator year-matched New Zealand Census population. One hundred sixty-one patients had confirmed bullous pemphigoid, with an incidence rate of 3.03/100 000 person-years [95% CI 2.58-3.54] 70% were of European ethnicity 12.4% were Pacific peoples 11.2% were Asian and 6.8% were Māori. 45.3% had associated cognitive impairment and/or stroke. In the 3-year follow-up, 25% had treatment complications mostly from prednisone therapy. The mortality rate was 40%, highest in the first year of diagnosis, with age at diagnosis a predictor. The incidence and mortality rates are comparable to the UK/Northern Europe. Knowledge of the epidemiology of bullous pemphigoid in New Zealand and within an international settling informs the provision of future care and treatments.

Abstract: The COVID‐19 pandemic has disrupted the practice of medicine. Dermatologic laser and energy‐based device (EBD) treatments carry a potential risk for the transmission of SARS‐CoV‐2 both for the patient and the practitioner. These risks include close practitioner to patient proximity, the treatment of higher viral load areas such as the face, the potential for infective bioparticles being carried by generated plumes and aerosols, and the direct contact between device, practitioner and patient. SARS‐CoV‐2 is a highly infective respiratory pathogen transmitted by respiratory droplets, respiratory/mucosal secretions, medically generated aerosols and via its transfer from contaminated fomites. This requires a review of the appropriateness of infection control protocols in regard to dermatologic laser and energy‐based device treatments. A critical evaluation of patient skin preparation including skin asepsis, device disinfection, laser and electrosurgical plume management and PPE in regard to SARS‐CoV‐2 was performed. The adherence to a high standard of skin preparation and asepsis, device disinfection, laser and electrosurgical plume and aerosol management and appropriate PPE should help mitigate or reduce some of the inherent treatment risks. Head and neck treatments along with aerosol and laser plume generating treatments likely carry greater risk. COVID‐19 needs to be considered in the clinic set‐up along with the planning, treatment and post‐treatment care of patients utilising EBD procedures. Some of these treatment precautions are COVID‐19 specific however, most represent adherence to good infectious disease and established laser and EBD safety precautions.
