RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted healthcare service provision worldwide. There is limited information on changes in invasive cardiovascular services during the pandemic, particularly in Australia. AIM: We sought to assess temporal trends on the use of interventional cardiology and cardiac surgery services before and following the COVID-19 pandemic in Australia. METHODS: Medicare Benefits Schedule items data from the Australian Government Services Australia on outpatient and private hospital interventional cardiology procedures (coronary angiogram, percutaneous coronary intervention and transcatheter aortic valve implantation) and cardiac surgery procedures (coronary artery bypass grafting [CABG] and surgical valve replacement, repair and annuloplasty) were analysed from March 2019 to 2021. This was superimposed on monthly COVID-19 case data obtained from the Australian Department of Health and Aged Care epidemiology reports. RESULTS: A sustained reduction in CABG (-10.1%) and surgical valve intervention (-11.1%) was appreciated from March 2019-2020 to March 2020-2021, in the first year of the COVID-19 pandemic. During this period, an overall increase (+25.9%) in the use of transcatheter aortic valve implantation was observed. Following the initial period of mandated isolation in March-April 2020, a reduction in coronary angiography (-29.1%) and percutaneous coronary intervention (-19.5%) was observed in comparison to March-April 2019; however, this was largely attenuated over time. CONCLUSIONS: The COVID-19 pandemic has resulted in reductions in the use of interventional cardiology and cardiac surgery services, with cardiac surgery most affected. However, an increase in uptake of transcatheter aortic valve implantation has been observed during the pandemic. This may have implications for future planning and resource allocation in the aftermath of the pandemic.

Inflammatory linear verrucous epidermal nevus (ILVEN) is a rare type of epidermal nevus, commonly arising in childhood. We present a case of a 13-year-old female with Blaschkoid psoriasiform plaques extending from her left foot to the scalp, sparing the right side of the body. While treatment options historically show variable success, we trialed an IL-17a receptor inhibitor as studies have shown increased levels of IL-17 receptor expression in ILVEN keratinocytes. At both 3 and 6 months after treatment initiation there was found to be significant improvement. We propose brodalumab as an effective treatment option for widespread ILVEN.

Hypertension continues to be the leading modifiable risk factor for stroke, kidney disease and cardiovascular disease, and it also plays a key role in a significant proportion of preventable deaths globally. Ambulatory blood pressure monitoring (ABPM) is an underutilised tool that augments the accurate diagnosis of hypertension. Out-of-office blood pressure measurements such as ABPM, permits the diagnosis of white coat hypertension and masked hypertension as well as determining a patient's nocturnal dipping status. These common clinical phenotypes have relevance with regard to clinical outcomes and may impact management. Overall, the diagnosis and management of hypertension presents numerous challenges, requiring the complementary use of multimodal blood pressure monitoring. Familiarity with the use of ABPM is important in the optimal management of patients, particularly as it becomes more accessible with the recent introduction of a Medicare Benefits Schedule item number.

BACKGROUND: Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common subtypes of cutaneous T-cell lymphoma (CTCL). There is currently no cure for CTCL, and treatment is aimed at limiting disease progression. This study evaluated the efficacy and tolerability of alitretinoin in CTCL management. METHODS: A retrospective, multicenter study was conducted on CTCL patients treated with alitretinoin as a primary agent or in combination with standard therapies. RESULTS: Forty-eight patients with MF (n = 40) and SS (n = 8) with a median age of 59.7 years (±14.3) were eligible for study inclusion. Treatment response data were evaluated in 40 patients and safety in 42 patients. 40.0% of the patients had early-stage, 43.8% had advanced-stage CTCL, and in 16.7% of patients there was insufficient information for staging. 40.0% (16/40) of the patients achieved a complete or partial response, whereas 47.5% (19/40) achieved stable disease, 12.5% (5/40) had progressive disease, and there were no cases of disease relapses in responders. Both early and advanced stages of CTCL were responsive to alitretinoin as a primary or combined modality. Alitretinoin was well tolerated, and 64.3% (27/42) of patients did not report any side effects. The most commonly observed side effect was hypertriglyceridemia. CONCLUSIONS: This retrospective analysis supports the efficacy and safety of alitretinoin in clearing skin disease and preventing disease progression in CTCL as a monotherapy or in combination with standard therapies.

OBJECTIVES: Describe the incidence of cardiac complications in patients admitted to hospital with COVID-19 in Australia. DESIGN: Observational cohort study. SETTING: Twenty-one (21) Australian hospitals. PARTICIPANTS: Consecutive patients aged ≥18 years admitted to hospital with laboratory confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. MAIN OUTCOME MEASURES: Incidence of cardiac complications. RESULTS: Six-hundred-and-forty-four (644) hospitalised patients (62.5±20.1 yo, 51.1% male) with COVID-19 were enrolled in the study. Overall in-hospital mortality was 14.3%. Twenty (20) (3.6%) patients developed new atrial fibrillation or flutter during admission and 9 (1.6%) patients were diagnosed with new heart failure or cardiomyopathy. Three (3) (0.5%) patients developed high grade atrioventricular (AV) block. Two (2) (0.3%) patients were clinically diagnosed with pericarditis or myopericarditis. Among the 295 (45.8%) patients with at least one troponin measurement, 99 (33.6%) had a peak troponin above the upper limit of normal (ULN). In-hospital mortality was higher in patients with raised troponin (32.3% vs 6.1%, p<0.001). New onset atrial fibrillation or flutter (6.4% vs 1.0%, p=0.001) and troponin elevation above the ULN (50.3% vs 16.4%, p<0.001) were more common in patients 65 years and older. There was no significant difference in the rate of cardiac complications between males and females. CONCLUSIONS: Among patients with COVID-19 requiring hospitalisation in Australia, troponin elevation was common but clinical cardiac sequelae were uncommon. The incidence of atrial arrhythmias and troponin elevation was greatest in patients 65 years and older.

BACKGROUND:: Mohs micrographic surgery (MMS) is a surgical modality that achieves high cure rates of nonmelanoma skin cancers but is dependent on accurate histologic examination of surgical margins. Therefore, quality assurance is essential to ongoing assessment of histological margins. OBJECTIVES:: To prospectively determine the concordance rate between a Mohs surgeon (MS) and dermatopathologist (DP) with respect to tumour status (ie, present or absent) and tumour type. Secondary end points were to determine the relationship between discordant interpretations and slide quality and to assess the feasibility of using an electronic webform for data collection. METHODS:: Ten percent (10%) of the planned MMS cases between January 2015 and March 2016 were randomly selected by a histotechnologist at the start of each month. The MS and DP were blinded to the chosen cases, and slides were reviewed independently at the beginning of the following month. Data were collected using an online webform. A blinded third party determined if there were discrepancies in interpretation, and any discordant slides were reviewed together and a consensus was reached. RESULTS:: A total of 270 slides from 54 total cases were reviewed. The overall tumour status concordance rate was 93.6%. Cohen's κ was 0.86. Tumour type concordance was 98.9%. No discrepancy required a change in patient care. All discrepant slides were from cases that required multiple stages. CONCLUSIONS:: This is the first study looking at MS-DP concordance in Canada, and our findings support the MS acting as his or her own pathologist.

Lichen myxedematosus is an idiopathic, cutaneous mucinosis with 2 clinicopathologic subsets. There is the generalised papular and sclerodermoid form, more properly termed scleromyxedema, and the localised papular form. We report the first case, to our knowledge, of lichen myxedematosus in association with rheumatoid arthritis as well as a case in association with dermatomyositis. An up-to-date literature review on cutaneous mucinoses and connective tissue diseases, excluding the common association of primary and secondary mucinoses with systemic lupus erythematosus, was also performed.

BACKGROUND: The impact of age of red blood cells on health-related quality of life (HRQL) in patients who require chronic transfusions is not known. We assessed this using n-of-1 trials in patient populations where large randomized trials have not been done to date. STUDY DESIGN AND METHODS: Chronically transfusion-dependent adult patients were randomly assigned over time to four fresh (<7 days of storage) and four standard-issue (up to 42 days of storage) blood transfusions in prospective double-blinded multicrossover studies (n-of-1 trials). HRQL questionnaires were completed before and at 24 hours after each transfusion. Hemoglobin (Hb) levels were measured before each subsequent transfusion. RESULTS: Twenty transfusion-dependent patients were enrolled, of whom nine (five myelodysplastic syndromes, two myelofibrosis, one ß-thalassemia major, one Diamond-Blackfan anemia) completed at least six transfusions. Mean ages of fresh and standard-issue blood transfused were 4.0 and 23.2 days, respectively. There were no significant differences in the effect of standard and fresh blood on follow-up Hb levels or the eight HRQL dimensions assessed in all analyses. CONCLUSIONS: In chronically transfused patients, there were no significant differences in HRQL or Hb levels between fresh versus standard blood. While larger trials are needed, these results support current practices in hospital blood transfusion laboratories using a first-in, first-out model of blood utilization for these transfusion-dependent patients. Use of n-of-1 trials to determine the benefits of transfusions in single patients appears to be feasible.

OBJECTIVE: In this study we aimed to examine the characteristics of Mental Health Act (MHA) usage in the Emergency Department (ED) of an urban teaching hospital in Sydney. METHODS: All MHA certificates written on individuals in the ED over a 12-week period in 2013 were collected. The medical record of each individual was reviewed by a member of the research team using an audit tool developed for the study. Any uncertainty over individual cases was addressed through research team consensus. RESULTS: A total of 172 MHA certificates were collected; 67 were written by police, 45 by ambulance, 54 by medical officers and three by accredited persons. Three magistrate orders for assessment were also received. Seventy percent of police and 60% of ambulance MHA certificates did not result in admission. Over a third were revoked by ED physicians. Forty-five people (32.4%) who presented voluntarily were subsequently detained. CONCLUSIONS: Police and ambulance MHA certification was a poor predictor of admission. Least restrictive measures were predominantly the outcome. Delegating ED physicians with authorised medical officer status assisted in facilitating this process. Formalised education and training on the principles and practicalities of MHA legislation should be ongoing for all professionals involved.

Mycobacterium elephantis was first described when isolated from an elephant that succumbed to lung abscess. However, despite this namesake, it is not associated with animals and has been described most often as a probable colonizer rather than pathogen in humans with chronic lung disease. In this report, we describe the first case of lymphocutaneous infection from M. elephantis, likely as a result of cutaneous inoculation with contaminated soil. This offers further evidence to its capabilities as a pathogen. We provide a review of the limited prior reports of M. elephantis and outline the available in vitro data on efficacy of various antimycobacterial agents.
RESUMO
OBJECTIVE: To assess whether hypertension is an independent risk factor for mortality among patients hospitalised with COVID-19, and to evaluate the impact of ACE inhibitor and angiotensin receptor blocker (ARB) use on mortality in patients with a background of hypertension. METHOD: This observational cohort study included all index hospitalisations with laboratory-proven COVID-19 aged ≥18 years across 21 Australian hospitals. Patients with suspected, but not laboratory-proven COVID-19, were excluded. Registry data were analysed for in-hospital mortality in patients with comorbidities including hypertension, and baseline treatment with ACE inhibitors or ARBs. RESULTS: 546 consecutive patients (62.9±19.8 years old, 51.8% male) hospitalised with COVID-19 were enrolled. In the multivariable model, significant predictors of mortality were age (adjusted OR (aOR) 1.09, 95% CI 1.07 to 1.12, p<0.001), heart failure or cardiomyopathy (aOR 2.71, 95% CI 1.13 to 6.53, p=0.026), chronic kidney disease (aOR 2.33, 95% CI 1.02 to 5.32, p=0.044) and chronic obstructive pulmonary disease (aOR 2.27, 95% CI 1.06 to 4.85, p=0.035). Hypertension was the most prevalent comorbidity (49.5%) but was not independently associated with increased mortality (aOR 0.92, 95% CI 0.48 to 1.77, p=0.81). Among patients with hypertension, ACE inhibitor (aOR 1.37, 95% CI 0.61 to 3.08, p=0.61) and ARB (aOR 0.64, 95% CI 0.27 to 1.49, p=0.30) use was not associated with mortality. CONCLUSIONS: In patients hospitalised with COVID-19, pre-existing hypertension was the most prevalent comorbidity but was not independently associated with mortality. Similarly, the baseline use of ACE inhibitors or ARBs had no independent association with in-hospital mortality.

PURPOSE: Omalizumab is a recombinant humanized monoclonal antibody that inhibits the binding of immunoglobulin E (IgE) to the high-affinity IgE receptor (FceRI) on the surface of mast cells and basophils. Omalizumab has been approved for use in asthma, and new reports show promise in a variety of dermatologic diseases. Herein, we review the literature on omalizumab in dermatology and discuss the safety, efficacy and mechanisms of action for this emerging therapy. MATERIALS AND METHODS: PubMED, MEDLINE and Embase databases were searched for the period 1 January 1990 to 1 September 2016. Articles sourced were graded according to the Oxford Center for Evidence-Based Medicine Levels of Evidence Grades of Recommendation criteria. RESULTS: A total of 99 articles met our inclusion criteria. They included reports on the use of omalizumab in chronic spontaneous urticaria, atopic dermatitis, mastocytosis, hyper-IgE syndrome, bullous pemphigoid, Netherton syndrome, urticarial vasculitis, Churg-Strauss syndrome and toxic epidermal necrolysis. CONCLUSIONS: Omalizumab is effective in a variety of recalcitrant immune-mediated and autoimmune skin disorders. It is a safe and effective treatment for use in chronic idiopathic urticaria (Grade of recommendation: A). Randomized clinical trials with long-term follow-ups are warranted to firmly establish the role of omalizumab in the treatment of dermatologic disease.
