Objectives
To determine the prevalence of eczema among children in New Zealand.
Methods
Population-based retrospective observational study utilising national pharmaceutical dispensing records for topical corticosteroids and emollients for all New Zealand children aged 0–14 years from 1st January 2006 to 31st December 2019. Data are reported using descriptive statistics, with comparisons between ethnicities and socioeconomic quintiles undertaken with rate ratios.
Results
Based on dispensing data, the prevalence of eczema for New Zealand children aged 0–14 years in 2018 was 14.0% (95% CI 14.0%–14.1%), with prevalence decreasing in older age groups (children aged <1 year 26.0% (25.6%–26.4%); children aged 10–14 years 8.8% (8.7%–8.9%)). Prevalence was higher in Pacific children (23.6% (23.3%–24.0%)), but slightly lower in Māori children (13.2% (13.0%–13.3%)).
Conclusion
Eczema is a common condition affecting a considerable proportion of children in New Zealand. This study provides nationwide paediatric prevalence data for New Zealand, and highlights the increased burden of eczema in Pacific children. Inequity in dispensing of topical corticosteroids is postulated to explain the reduced rates found for Māori children compared to previous studies. These results support the need for further research to determine factors contributing to differing eczema prevalence rates in New Zealand.
目标：确定新西兰儿童湿疹的发病率：确定新西兰儿童湿疹患病率：基于人群的回顾性观察研究，利用2006年1月1日至2019年12月31日期间所有0-14岁新西兰儿童的局部皮质类固醇激素和润肤剂的国家药品配发记录。数据采用描述性统计方法进行报告，种族和社会经济五分位数之间采用比率进行比较：根据配药数据，2018年新西兰0-14岁儿童的湿疹患病率为14.0%（95% CI 14.0%-14.1%），患病率在较大年龄组中有所下降（0-14岁儿童的患病率为14.0%-14.1%）：湿疹是一种影响新西兰相当一部分儿童的常见疾病。这项研究提供了新西兰全国范围内的儿科发病率数据，并强调了太平洋地区儿童湿疹负担加重的问题。据推测，与以往的研究相比，毛利儿童的湿疹发病率较低的原因是局部皮质类固醇激素配药不公平。这些结果支持了进一步研究的必要性，以确定导致新西兰湿疹患病率不同的因素。

<p>Vulvovaginal lichen planus (VLP) is a chronic inflammatory dermatosis of the vulva with or without vaginal involvement.

DIV and VLP can pose significant diagnostic challenges as both have a wide range of clinical manifestations and histopathological findings, which often overlap.

外阴阴道扁平苔藓（VLP）是一种慢性外阴炎症性皮肤病，可累及或不累及阴道。由于形态学和组织病理学结果的差异，其诊断可能具有挑战性。1 DIV是一种不常见的非感染性外阴阴道炎，以疼痛、排便困难、瘙痒和白色或绿色非致病性分泌物为特征。1 DIV 是一种不常见的非感染性外阴阴道炎，其特征是疼痛、排便困难、瘙痒和白色或绿色非排泄性分泌物，但与 VLP 不同的是，它不是一种瘢痕性疾病。2 在此，我们介绍了一组病例，这些妇女最初被诊断为 DIV，但对通常非常有效的外用克林霉素治疗无效（表 1）。据我们所知，这是自1988年以来报告的唯一一个类似DIV的VLP患者病例系列。DIV和VLP会给诊断带来巨大挑战，因为这两种疾病的临床表现和组织病理学检查结果多种多样，而且往往相互重叠。在组织学上，这两种疾病都会出现苔藓样浸润，而观察到的变化往往被报告为 "非特异性"。5、6 检查时通常会观察到红斑、瘀点或点状糜烂。2、3 同时，在 VLP 中通常观察不到脓性分泌物。DIV 不会导致瘢痕形成，而 VLP 通常表现为釉面红斑、糜烂和角化过度，如果不及时治疗，常常会导致瘢痕形成、外阴结构缺失和阴道狭窄。在我们的病例系列中，所有患者均可观察到瘀斑。这表明，虽然瘀斑在 VLP 中并不常见，8 但这些瘀斑可能是模仿 DIV 的 VLP 的一个小亚型。此外，与病例 3 一样，口腔粘膜受累也可能为 VLP 诊断提供额外线索。耐药性也应促使临床医生考虑其他诊断，因为 DIV 通常对局部抗生素治疗反应迅速，尤其是 2% 的克林霉素。Bradford 等人的一项研究比较了 101 例 DIV 和 75 例 VLP。2 大多数 DIV 患者（94%）对阴道内使用 4-6 周 2% 的克林霉素有反应，其中 35% 需要维持治疗。在 Sobel 等人对 130 名 DIV 患者进行的另一项为期 12 年的研究中，86% 的患者在开始使用 2% 的克林霉素或 10%的氢化可的松乳膏 3 周内症状明显改善。在 Bradford 等人的研究中，半数以上的 DIV 患者（56%）报告了历史诱因，而 VLP 组仅为 15%（p < 0.0001）2。在本系列病例中，有两名患者疑似患有慢性外阴阴道念珠菌病（CVVC）。一名患者在发病前曾因服用拉莫三嗪而出现伴有嗜酸性粒细胞增多和全身症状的药物反应（DRESS）。我们的患者中只有一人能够通过外用皮质类固醇得到控制，其他人都需要系统治疗。对于已确诊为 DIV 并表现出抗药性的患者，应考虑 VLP 的替代诊断。其他身体部位（如口腔粘膜）受累也有助于 VLP 的诊断。所有患者均同意将其病例纳入本报告并在期刊上发表。本报告中包含的患者照片已征得患者同意。

In comparison with TNF-α inhibitors, anti-IL-17A agents are considered to have a lower risk of active tuberculosis (TB) or latent TB infection (LTBI) reactivation.
Methods
In this study, we aimed to evaluate the TB infection status and serial QuantiFERON-TB-Gold in tube test (QFT) results of psoriasis patients using IL-17 inhibitors (secukinumab [SEC] and ixekizumab [IXE]) in a real-world setting from a tuberculosis-endemic country. Patients who used an anti-IL-17 agent for at least 3 months in our follow-up were included in the study. Patients' clinical and demographic features, baseline QFT results and latest QFT results (if any), and TB infection status were noted from the past medical records.
Results
A total of 717 patients, of whom 333 (46.4%) were female, were included in the study. The cumulative exposure time to an anti-IL-17 agent was 14,147 patient-months, 9743 patient-months for SEC and 4404 patient-months for IXE. Also, 459 (SEC = 305/IXE = 154) patients used an anti-IL-17 agent for ≥ 12 months. Of these, 125 had positive baseline QFT results. In all, 334 had negative baseline QFT results. The latest QFT result of 309 was also negative (persistent seronegative group). During follow-up, the QFT results of 10 patients changed from negative to positive (positive seroconversion group). Seven of them were using SEC and three were using IXE, respectively. No case of active TB infection was detected.
Conclusion
In our study, the positive seroconversion rate of 10/334 seems high, but this did not translate to active disease. However, closer monitoring may be required, especially in patients with advanced age, the presence of PsA, long disease duration and long anti-IL-17 treatment duration.

Background/Objectives
Caucasian and Asian patients with hidradenitis suppurativa demonstrate significant differences with regard to age, gender and body mass index. Demographic characteristics are known to influence the efficacy and drug survival of hidradenitis suppurativa therapeutics including biologic therapies. What remains unknown is the impact of ethnicity upon the efficacy of therapeutics once demographic and disease characteristics have been taken into account. This is an important question given the expansion of biologic therapies for HS into the global patient community.
Methods
We assessed 170 patients from a single HS specialist centre in Australia stratified by patient-identified ethnicity including those identifying as either Caucasian or Asian.
Results
Asian patients demonstrated lower BMI, higher rates of smoking and greater odds of Hurley stage 3 disease with tunnels than Caucasian patients in line with the reported literature. There was no significant difference between percentage of individuals achieving HiSCR50 or IHS4-55 at Week 16. Significant differences were seen in median time to secondary loss of response, and Kaplan–Meier curve analysis showed a significant difference between curves when stratified by patient-reported ethnicity. Cox regression analysis demonstrated after accounting for age, gender, BMI, smoking and Hurley stage, the significance of ethnicity in influencing time to secondary loss of response disappears.
Conclusions
Caucasian or Asian ethnicity does not influence response to adalimumab treatment on patients with hidradenitis suppurativa.

Royal Darwin Hospital (RDH) is the sole public dermatology service in the Northern Territory (NT). Prescription of biologic therapies (BT) in the NT is uniquely challenging, with remote populations carrying a high tropical disease burden. The aim of this audit is to examine the demographics and outcomes of patients on BT for dermatologic conditions.
Methods
Retrospective case note review of patients receiving BT through the RDH Dermatology department between August 2021 and October 2023. Data analysed were demographics, location, dermatological diagnosis and serology status.
Results
In this audit, 115 patients were included. Age range of 13–91 years, mean of 51.1 years (±14.7), 52 (45.2%) patients were female and 8 (7.8%) identified as First Nations Australian. A large geographical area was serviced, with a primary address between 1 and 1496 km from RDH. Eighteen patients (15.7%) have discontinued BT completely. There was a statistically significant relationship between cessation of BT and increased distance of primary residence from RDH (p < 0.0007). Eighteen patients (15.7%) required management of infections identified in opportunistic infection screening. These infections were strongyloidiasis, tuberculosis, melioidosis and hepatitis B.
Conclusions
There is significant anxiety surrounding BT and tropical infections, including in returning travellers in southern Australian states. There has been particular interest in strongyloidiasis infection, as dupilumab acts on the Th2 immunity mechanism critical to parasitic infection response. This audit exhibits the unique experience of dermatological care in a tropical setting, demonstrating how BT can be used safely and how, when identified, these tropical infections can be successfully managed.

Beta-blockers have been established as a treatment of infantile haemangiomas (IH) since its serendipitous discovery for use in IH in 2008. However, data on the safety of these beta-blockers for use in IH in preterm infants are scarce. A retrospective study was performed to review the safety of oral propranolol and topical timolol in the treatment of IH in a cohort of preterm infants treated at our tertiary paediatric hospital. It was observed that there was an increased risk of adverse events amongst the preterm infants with chronic lung disease, retinopathy of prematurity and gastroesophageal reflux, when treated with oral propranolol.
自 2008 年偶然发现β-受体阻滞剂可用于治疗婴儿血管瘤（IH）以来，β-受体阻滞剂已被确定为治疗婴儿血管瘤的一种方法。然而，有关这些β-受体阻滞剂用于早产儿血管瘤安全性的数据却很少。我们开展了一项回顾性研究，对在我们的三级儿科医院接受治疗的早产儿队列中口服普萘洛尔和外用噻吗洛尔治疗 IH 的安全性进行了回顾。研究发现，在使用口服普萘洛尔治疗时，患有慢性肺病、早产儿视网膜病变和胃食管反流的早产儿发生不良事件的风险增加。

Dermatologists' burnout is a growing phenomenon. During the last years, an important role on medical stress is played by the ever-increasing use of common technological devices (smartphones, smartwatches, PCs and tablets). The aim of the study was to investigate whether digital technology use causes burnout among Italian dermatologists, using a survey conducted among a group of Italian dermatologists. The final sample contained 194 responses valid for analysis. A positive and significant relationship between technostress, assessed through Technostress Inventory and burnout, assessed through Maslach Burnout Inventory, among Italian dermatologists was found. Our data seems suggesting a close relationship between technostress and dermatologist burnout.
