The Psychology of Atopic Dermatitis.

Atopic dermatitis (AD) is a common chronic inflammatory skin condition characterised by pruritus and recurrent eczematous patches and plaques. It impacts sleep and its visibility can lead to stigmatisation, low self-esteem, social withdrawal, reduced quality of life (QOL), and psychological burden. This study explores the relationship between AD and mental health, including possible causation pathways. A literature review was conducted in PubMed without using limiters. AD carries higher odds of suicidality and an increased risk of depression, anxiety, alexithymia, and obsessive-compulsive disorder (OCD) across all severities. While some studies report an association of AD with attention deficit hyperactivity disorder (ADHD), and possibly autism spectrum disorder (ASD), others do not. There is increasing evidence that AD contributes to chronic low-grade inflammation and cognitive impairment (CI). Causative factors for mental health complications of AD likely include both psychosocial and biological variables. AD is associated with higher levels of cutaneous and circulating proinflammatory cytokines; these can breach the blood-brain barrier and trigger central nervous system events, including oxidative stress, neurotransmitter breakdown, altered serotonin metabolism, and reduced neurogenesis in several brain regions. Excessive inflammation in AD may thus contribute to CI, depression, and suicidality. AD providers should be vigilant about mental health.

Burden of Disease and Unmet Needs in the Diagnosis and Management of Atopic Dermatitis in Diverse Skin Types in Australia.

Atopic dermatitis (AD) is a common, chronic, inflammatory skin disease affecting Australians of all ages, races, ethnicities, and social classes. Significant physical, psychosocial, and financial burdens to both individuals and Australian communities have been demonstrated. This narrative review highlights knowledge gaps for AD in Australian skin of colour. We searched PubMed, Wiley Online Library, and Cochrane Library databases for review articles, systematic reviews, and cross-sectional and observational studies relating to AD in Australia for skin of colour and for different ethnicities. Statistical data from the Australian Institute of Health and Welfare and the Australian Bureau of Statistics was collected. In recent years, there has been substantially increased awareness of and research into skin infections, such as scabies and impetigo, among various Australian subpopulations. Many such infections disproportionately affect First Nations Peoples. However, data for AD itself in these groups are limited. There is also little written regarding AD in recent, racially diverse immigrants with skin of colour. Areas for future research include AD epidemiology and AD phenotypes for First Nations Peoples and AD trajectories for non-Caucasian immigrants. We also note the evident disparity in both the level of understanding and the management standards of AD between urban and remote communities in Australia. This discrepancy relates to a relative lack of healthcare resources in marginalised communities. First Nations Peoples in particular experience socioeconomic disadvantage, have worse health outcomes, and experience healthcare inequality in Australia. Barriers to effective AD management must be identified and responsibly addressed for socioeconomically disadvantaged and remote-living communities to achieve healthcare equity.

Haemophagocytic lymphohistiocytosis as a complication of combination anti-PD-1 and anti-CTLA-4 checkpoint inhibitor immunotherapy for metastatic melanoma, and the outcome of rechallenge with single-agent anti-PD-1 immunotherapy.

A woman with metastatic melanoma was treated with immunotherapy induction with ipilimumab and nivolumab and radiotherapy to liver metastases. The patient deteriorated shortly thereafter, becoming febrile and hypotensive and requiring admission to the intensie care unit (ICU) for inotrope support. Failure to respond to antibiotics and a negative septic screen prompted further investigation, which ultimately led to a diagnosis of haemophagocytic lymphohistiocytosis (HLH). The patient improved on high dose steroids and was discharged home. Months later, in the context of progressive melanoma, the patient was re-challenged with nivolumab monotherapy and subsequently experienced recurrence of HLH, confirming the aetiology as being immunotherapy related. This case serves as a reminder to consider HLH where there are fevers of unknown origin in an unwell patient receiving immune checkpoint inhibitor therapy and also highlights immunotherapy as a potential cause for HLH, which has rarely been reported in the literature to date.

Rash morphology as a predictor of COVID-19 severity: A systematic review of the cutaneous manifestations of COVID-19.

Approximately 6% of those with COVID-19 will experience cutaneous manifestations. Examining data from this cohort could provide useful information to help with the management of COVID-19. To that end, we conducted a systematic review primarily to assess rash morphologies associated with COVID-19 and their relationship with disease severity. Secondary outcomes include demographics, distribution, dermatological symptoms, timeline, diagnostic method and medication history. The literature was searched for all patients with skin manifestations thought to be related to suspected or confirmed COVID-19. Patients with a history of dermatological, rheumatological or occupational skin disorders were excluded. Of the 2056 patients selected, the most common morphologies were chilblain-like lesions (54.2%), maculopapular (13.6%) and urticaria (8.3%). Chilblain-like lesions were more frequent in the younger population (mean age 21.5, standard deviation ± 10.8) and were strongly linked with milder disease, not requiring an admission (odds ratio [OR] 35.36 [95% confidence interval {CI} 23.58, 53.03]). Conversely, acro-ischaemia and livedo reticularis were associated with worse outcomes, including a need for ICU (OR 34.01 [95% CI 16.62, 69.57] and OR 5.57 [95% CI 3.02, 10.30], respectively) and mortality (OR 25.66 [95% CI 10.83, 60.79] and OR 10.71 [95% CI 4.76, 24.13], respectively). Acral lesions were the most common site (83.5%). 35.1% experienced pruritus, 16.4% had pain and 4.7% reported a burning sensation. 34.1% had asymptomatic lesions. Rash was the only symptom in 20.9% and occurred before or alongside systemic symptoms in 12.4%. 28.3% had a positive polymerase chain reaction nasopharyngeal swab and 5.4% had positive antibodies, while 21.9% tested negative and 45.1% were not tested. In conclusion, COVID-19 causes a variety of rashes, which may cause symptoms and add to morbidity. Rash type could be helpful in determining COVID-19 prognosis.

If your ears are burning we must be talking about red ear syndrome: A brief report.

Red Ear Syndrome is an uncommon disorder that can affect all age groups. It is frequently referred to Dermatology as it can present similarly to erythromelalgia. Although the exact pathophysiology is unknown, a common hypothesis suggests a shared pathophysiological background with migraine due to their well-known association. Currently, there are no established treatment guidelines. Delays in accurate diagnosis and commencing optimal treatment can significantly negatively impact on a patients quality of life. We discuss the clinical presentation and response to treatment of a case of Red Ear Syndrome in an 8-year-old boy.
