Red in the face: Approach to diagnosis of red rashes on the face.

BACKGROUND: A red rash on the face in an adult patient is a common presentation to general practice in Australia. Rashes on the face significantly affect quality of life because this is a cosmetically sensitive site. Ascertaining the correct diagnosis is therefore of utmost importance so that appropriate treatment can be initiated. OBJECTIVE: This article discusses the assessment of red rashes on the face in an adult patient. DISCUSSION: Diagnosing a red rash on the face requires assessment of symptomology, age of onset, rash morphology and 'clinical clues' that help delineate between differentials. Although the list of differential diagnoses is wide, many of the common diagnoses can be made clinically without the need for investigations. Investigations such as skin biopsy are useful if the diagnosis is unclear, if the rash is not responding to initial treatment and/or a referral to a dermatologist is being considered.

Approach to red, scaly eruptions in the older patient.

BACKGROUND: Older patients with a red scaly eruption often present first to a primary care practitioner. A thorough clinical assessment can help delineate between common causes and assist the clinician with the next steps in management. OBJECTIVE: This article discusses the assessment of acute- to subacute-onset erythematous and scaly plaques that are present on multiple body sites in a patient aged >65 years. DISCUSSION: The differential diagnosis of a red, scaly rash in an older patient includes atopic dermatitis, psoriasis, generalised drug eruption, tinea, scabies and non-bullous pemphigoid. Less common causes include subacute cutaneous lupus and mycosis fungoides. If the diagnosis is unclear after clinical assessment, a skin biopsy sent for histopathology, and/or direct immunofluorescence can be very useful. Management requires consideration of physical impairments, carer availability and cost.

Investigation of cancer incidence in ELSA-Brasil.

Low- and middle-income countries have high cancer-related mortality rates, and Brazil has one of the highest incidences of all cancers in South America. Since 2008, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) follows up 15,105 civil adult servants of college education and research institutions in six Brazilian capitals, collecting relevant information on risk factors for the incidence of cancer and other noncommunicable diseases. This study aimed to describe the methodology for surveillance and investigation of the incidence of primary cancers in ELSA-Brasil. The surveillance and investigation involve annual telephone interviews, data collection of medical registries (biopsy records, chemotherapy/radiotherapy reports, hospital records or death certificates/autopsy statements), eligibility and final classification, date and basis of diagnosis, tumor topography and histological type. The cumulative incidence of all types of cancer in ELSA-Brasil during the first five years of follow-up (2009-2013) was 2.27 %. The challenges encountered in the investigation process are related to the lack of data on the occurrence of distant metastasis and essential details regarding diagnoses. However, the quality control and the adequacy of the methods adopted enables the construction of a solid and pioneering database in the country, which will contribute to advance in research on the natural history of the most frequent types of cancer.

Kidney function decline associated with proton pump inhibitors: results from the ELSA-Brasil cohort.

OBJECTIVE: Investigate the longitudinal association of use and time of use of proton pump inhibitors (PPI) with incidence of chronic kidney disease (CKD) and kidney function change. METHODS: Prospective study with 13,909 participants from baseline (2008-2010) and second wave (2012-2014) of the ELSA-Brasil (mean interval between visits = 3.9 years (1.7-6.0)). Participants answered about use and time use of the PPI in the two weeks prior the interview. Renal function was assessed by glomerular filtration rate estimated by the Collaboration Equation for the Epidemiology of Chronic Kidney Disease. Values below 60ml/min/1.73 m² in wave 2 were considered incident CKD. Associations between PPI use and time of use at baseline and incident CKD and decline in renal function were estimated, respectively, by logistic regression and linear models with mixed effects, after adjusting for confounders. RESULTS: After adjustments, PPI users for more than six months had an increased risk of CKD compared to non-users. Compared to non-users, users PPIs for up to six months and above six months had greater decline in kidney function over time. CONCLUSION: This cohort of adults and elderly, after a mean interval of 3.9 years, PPI use and initial duration were associated with kidney function change between visits.

Erythema Multiforme Induced by a "Milker's Nodule" Pseudocowpox Infection: A Case Report and Review of Literature.

Milker's nodule is caused by the pseudocowpox virus following inoculation from infected cattle. We report the case of erythema multiforme induced by pseudocowpox infection in an 18-year-old female from regional Australia. While erythema multiforme has been described as a complication of orf, it is rare as a sequela of pseudocowpox infection. Greater clinical knowledge of this disease and potential complications aid in guiding appropriate management of this phenomenon.

Lack of association between proton pump inhibitor use and decline in cognitive performance in the ELSA-Brasil cohort.

OBJECTIVE: The study aims to investigate the longitudinal association of use and time of use of proton pump inhibitors (PPIs) with decreased performance in three cognitive tests. METHODS: Prospective cohort study included 7115 participants with mean age of 58.9 years at baseline (2008-2010) who participated in the second wave (2012-2014) of ELSA-Brasil (average interval between visits = 3.9 years (range: 1.7 to 6.0 years)). Cognitive performance was assessed by tests of memory, phonemic and semantic verbal fluency, and the trail making test, applied to both waves. Associations with the use and time of use of PPIs at baseline were investigated using linear models with mixed effects after adjusting for confounding factors. RESULTS: At baseline, 7.4% (529) of the participants used PPIs on a regular basis. After all adjustments, the interaction term use of PPI × age was not statistically significant for the cognitive tests evaluated, indicating that the use of PPI at baseline was not associated with a more accelerated decline in cognitive performance between waves. The interaction term PPI use × age was not statistically significant, in any of the categories of medication use time, any of the cognitive function tests evaluated, indicating that PPI use time is not associated with decrease in cognitive scores as the time interval between visits increases. CONCLUSION: In this cohort middle-aged and elderly adults, after average interval of 3.9 years (relatively short time to detect cognitive decline in a young cohort), the use and time of use of PPIs at the beginning of the study were not associated with a decline in cognitive performance in these tests between visits.

Association between ventilatory efficiency, oxygen uptake, and Glittre-ADL test results in patients with chronic heart failure: a preliminary study.

OBJECTIVE: The Glittre-ADL test (GA-T) is a functional capacity test that stands out for encompassing multiple tasks similar to activities of daily living. As ventilatory efficiency is one of the variables valued in the prognosis of chronic heart failure (CHF), this study aimed to evaluate associations between functional capacity and ventilatory variables in patients with CHF during the GA-T. RESULTS: Eight patients with CHF and New York Heart Association (NYHA) functional classification II-III underwent the GA-T coupled with metabolic gas analysis to obtain data by means of telemetry. The median total GA-T time was 00:04:39 (00:03:29-00:05:53). Borg dyspnoea scale scores before and after the GA-T were 2 (0-9) and 3 (1-10), respectively (P = 0.011). The relationship between the regression slope relating minute ventilation to carbon dioxide output (VE/VCO2 slope) was correlated with the total GA-T time (rs = 0.714, P = 0.047) and Borg dyspnoea score (rs = 0.761, P = 0.028). The other ventilatory variables showed no significant correlations. Our results suggest that the total GA-T time can be applied to estimate the ventilatory efficiency of patients with CHF. Future studies may use the GA-T in conjunction with other functional capacity tests to guide the treatment plan and evaluate the prognosis.

A Survey on Knowledge Gaps in Assessment and Management of Severe Drug Hypersensitivity Reactions: Multicenter Cross-Sectional Study of Australian Health Care Providers.

Severe drug hypersensitivity reactions (DHRs) are often encountered by health care professionals (HCPs). We evaluated knowledge of doctors and pharmacists in the assessment and management of severe DHRs using a structured questionnaire. A cross-sectional study was conducted in 4 metropolitan hospital networks in Melbourne, Australia. A 13-question, scenario-based multiple-choice questionnaire to assess specific knowledge domains in drug hypersensitivity syndrome recognition, causality attribution, cross-reactivity patterns, appropriate diagnostic tests, and therapy was administered to HCPs of various vocation and specialty groups. Data were analyzed according to profession, self-reported experience, and preparedness in managing severe DHRs. Two hundred thirty-eight participants (45.0% senior doctors, 24.4% junior doctors, and 30.7% pharmacists) across a range of subspecialties achieved an overall median score of 7 (IQR, 5-8)-overall 55.6% correct responses to all questions-with senior doctors outperforming junior doctors and pharmacists (P < .001). The best performance by all participants was in DHR syndrome recognition (60.9%), and the poorest was in diagnostics/therapy (52.0%). HCP group and experience level were significantly associated with better performance in the knowledge domains of cross-reactivity and diagnostics/therapy (P = .003 and < .001, respectively), but not in the domains of syndrome recognition and causality attribution (P > .05). Levels of self-reported preparedness in DHR management were not associated with performance rates in any of the knowledge domains. This study demonstrated significant knowledge gaps in the recognition and management of severe drug hypersensitivity reactions. Targeted multidisciplinary education of staff caring for these patients is needed to improve knowledge gaps.

Hypertension, Prehypertension, and Hypertension Control: Association With Decline in Cognitive Performance in the ELSA-Brasil Cohort.

Hypertension, particularly in middle age, has been associated with worse cognitive function, but evidence is inconclusive. This study investigated whether hypertension, prehypertension, age, and duration of diagnosis, as well as blood pressure control, are associated with a decline in cognitive performance in ELSA-Brasil participants. This longitudinal study included 7063 participants, mean age 58.9 years at baseline (2008-2010), who attended visit 2 (2012-2014). Cognitive performance was measured in both visits and evaluated by the standardized scores of the memory, verbal fluency, trail B tests, and global cognitive score. The associations were investigated using linear mixed models. Hypertension and prehypertension at baseline were associated with decline in global cognitive score; being hypertension associated with reduction in memory test; and prehypertension with reduction in fluency test. Hypertension diagnose ≥55 years was associated with lower global cognitive and memory test scores, and hypertension diagnose <55 years with lower memory test scores. Duration of hypertension diagnoses was not associated with any marker of cognitive function decline. Among treated individuals, blood pressure control at baseline was inversely associated with the decline in both global cognitive and memory test scores. In this relatively young cohort, hypertension, prehypertension, and blood pressure control were independent predictors of cognitive decline in distinct abilities. Our findings suggest that both lower and older age of hypertension, but not duration of diagnosis, were associated with cognitive decline in different abilities. In addition to hypertension, prehypertension and pressure control might be critical for the preservation of cognitive function.

Think before you shave: Factors influencing choice of biopsy technique for invasive melanoma and effect on definitive management.

BACKGROUND/OBJECTIVE: Partial biopsies are sometimes used for melanoma diagnosis with anticipated time and cost savings compared to excisional biopsy. However, their impact on subsequent melanoma management is unknown. Determine factors related to choice of partial over excisional biopsy to diagnose invasive melanoma and examine the effect of partial biopsies on definitive melanoma management. METHOD: Retrospective repeated cross-sectional population-based study through the Victorian Cancer Registry of diagnosed melanomas in 2005, 2010 and 2015. A random sample of 400 patients per year, stratified by tumour thickness, was selected. RESULTS: A total of 1200 patients had 833 excisional and 337 partial biopsies. Omission of suspected diagnosis on pathology requests affected 46% (532/1151) of all diagnostic biopsies. Diagnostic suspicion did not influence preference for partial over excisional biopsy [Odds Ratio (OR) 1.2, 95%CI 0.8-1.7; P = 0.40]. The partial:excisional biopsy usage ratio was higher in patients aged > 50 years than patients aged <50 years [relative risk ratios (RRR) 1.5; 95%CI 1.0 to 2.2; P = 0.03]. In 34% and 17% of tumours diagnosed with punch and shave, respectively, three procedures were required for definitive excision instead of two, compared with 5% of excisional biopsies When partial biopsy was used, patients were at greater risk of requiring three-staged excisions when controlled for age, anatomical site, melanoma subtype and thickness (RRR 6.7; 95%CI 4.4-10.1; P < 0.001). CONCLUSION: Diagnostic suspicion does not appear to be a major factor influencing choice of biopsy technique. Using partial biopsy to diagnose melanoma often leads to an extra procedure for definitive treatment compared with excisional biopsy.

The increasing use of shave biopsy for diagnosing invasive melanoma in Australia.

OBJECTIVE: To assess changes in the choice of skin biopsy technique for assessing invasive melanoma in Victoria, and to examine the impact of partial biopsy technique on the accuracy of tumour microstaging. DESIGN: Retrospective cross-sectional review of Victorian Cancer Registry data on invasive melanoma histologically diagnosed in Victoria during 2005, 2010, and 2015. SETTING, PARTICIPANTS: 400 patients randomly selected from each of the three years, stratified by final tumour thickness: 200 patients with thin melanoma (< 1.0 mm), 100 each with intermediate (1.0-4.0 mm) and thick melanoma (> 4.0 mm). MAIN OUTCOME MEASURES: Partial and excisional biopsies, as proportions of all skin biopsies; rates of tumour base transection and T-upstaging, and mean tumour thickness underestimation following partial biopsy. RESULTS: 833 excisional and 337 partial diagnostic biopsies were undertaken. The proportion of partial biopsies increased from 20% of patients in 2005 to 36% in 2015 (P < 0.001); the proportion of shave biopsies increased from 9% in 2005 to 20% in 2015 (P < 0.001), with increasing rates among dermatologists and general practitioners. Ninety-four of 175 shave biopsies (54%) transected the tumour base; wide local excision subsequently identified residual melanoma in 65 of these cases (69%). Twenty-one tumours diagnosed by shave biopsy (12%) were T-upstaged. With base-transected shave biopsies, tumour thickness was underestimated by a mean 2.36 mm for thick, 0.48 mm for intermediate, and 0.07 mm for thin melanomas. CONCLUSION: Partial biopsy, particularly shave biopsy, was increasingly used for diagnosing invasive melanoma between 2005 and 2015. Shave biopsy has a high rate of base transection, reducing the accuracy of tumour staging, which is crucial for planning appropriate therapy, including definitive surgery and adjuvant therapy.

Improving diagnostic accuracy for suspicious melanocytic skin lesions: New Australian melanoma clinical practice guidelines stress the importance of clinician/pathologist communication.

BACKGROUND: Incorrect or delayed diagnosis of melanoma may lead to inappropriate treatment, poor clinical outcomes, increased cost and medicolegal consequences. The provision of pertinent clinical information is essential for accurate pathological diagnosis of cutaneous melanocytic tumours. Failure to provide this information may contribute to poor outcomes. OBJECTIVE: The aim of this article is to highlight important clinical information that clinicians can provide to pathologists to facilitate accurate diagnosis of melanocytic tumours. DISCUSSION: Pertinent clinical information includes patient age, sex, tumour site, specimen orientation (if appropriate), history of the lesion, presence of any clinically or dermoscopically suspicious areas within the lesion (including apparent regression), access to any relevant clinical and/or dermoscopic photographs and prior pathology reports, melanoma history and risk factors, and history of concurrent or recent pregnancy. If the clinical features are not concordant with the pathology findings, the clinician and pathologist should discuss the case to identify the reason for incongruence.

Adverse Drug Reactions Reported by Healthcare Professionals: Reaction Characteristics and Time to Reporting.

We describe adverse drug reaction (ADR) reporting characteristics and factors contributing to length of time to report by healthcare professionals. This is a retrospective study of voluntary reports to an Australian healthcare ADR Review Committee over a 2-year period (2015-2016). Descriptive and univariate models were used for outcomes, employing standardized ADR definitions. Hospital pharmacists reported 84.8% of the 555 ADRs: 70.3% were hospital onset reactions, and 71.7% were at least of moderate severity. Immunologically mediated reactions were most commonly reported (409, 73.7%). The median time to submit an ADR report was 3 (interquartile range 1-10) days. Longer median times to reporting were associated with multiple implicated agents and delayed hypersensitivity reactions, especially severe cutaneous adverse reactions. A total of 650 medications were implicated that involved multiple agents in 165/555 (29.7%) reports. Antimicrobials were the most commonly implicated agents. Immunologically mediated reactions were most commonly associated with antimicrobials and radiocontrast agents (P < .0001, odds ratio [OR] 3.6, 95%CI 2.4-5.5, and P = .04, OR 4.2, 95%CI 1.2-18.2, respectively). Opioids and psychoactive medications were more commonly implicated in nonimmunological reported ADRs (P = .0002, OR 3.9, 95%CI 1.9-7.9, and P < .0001, OR 11.4, 95%CI 4.6-27.8, respectively). Due to the predominant reporting of immunologically mediated reactions, a targeted education program is being planned to improve identification and accuracy of ADR reports, with the overall aim of improved management to ensure quality service provision and patient safety.

Lack of association between depression and C-reactive protein level in the baseline of Longitudinal Study of Adult Health (ELSA-Brasil).

BACKGROUND: Depression has been linked to increased levels of inflammatory markers in clinical studies, but results from general population samples are inconsistent. We aimed to investigate whether depression was associated with serum CRP levels in a cross-sectional analysis of a large cohort from a middle-income country. METHODS: We analyzed baseline data from 14,821 participants (35-74 years) of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Current depression (last 7 days) was assessed by the Clinical Interview Schedule-Revised (CIS-R). Because individuals on antidepressants could be negative on CIS-R due to their therapeutic effect, the explanatory variable had three categories: (1) negative on CIS-R and not using antidepressant (reference); (2) negative on CIS-R but using antidepressant; (3) positive on CIS-R with/without antidepressant use. Associations with CRP were investigated by general linear model (GLM). RESULTS: After adjustments for confounders, neither current depression, nor antidepressant use was statistically associated with elevated CRP levels. Additionally, analyzes stratified by gender, type and severity of depression did not change the results. LIMITATIONS: The reference group in our analysis might include participants with a lifetime history of depression. Additionally, the exclusion of questions on weight fluctuation and appetite from the CIS-R applied in ELSA-Brasil may have slightly underestimated the prevalence of depression, as well as limited our ability to assess the presence of somatic symptoms. CONCLUSION: This study found no association between current depression, use of antidepressants, and serum CRP levels.

A Case of Cutaneous Inflammatory Myofibroblastic Tumor.

Inflammatory myofibroblastic tumor (IMT) rarely occurs as a primary cutaneous lesion. We report a case of cutaneous IMT in an 8-year-old girl presenting with an ulcerated nodule on the cheek. Although cutaneous IMT poses a diagnostic challenge because of its rarity, excision of the lesion is likely to be curative.

Near-peer education: a novel teaching program.

OBJECTIVE: This study aims to: 1) Evaluate whether a near-peer program improves perceived OSCE performance; 2) Identify factors motivating students to teach; 3) Evaluate role of near-peer teaching in medical education. METHODS: A near-peer OSCE teaching program was implemented at Monash University's Peninsula Clinical School over the 2013 academic year. Forty 3rd-year and thirty final-year medical students were recruited as near-peer learners and educators, respectively. A post-program questionnaire was completed by learners prior to summative OSCEs (n=31), followed by post-OSCE focus groups (n=10). Near-peer teachers were interviewed at the program's conclusion (n=10). Qualitative data was analysed for emerging themes to assess the perceived value of the program. RESULTS: Learners felt peer-led teaching was more relevant to assessment, at an appropriate level of difficulty and delivered in a less threatening environment than other methods of teaching. They valued consistent practice and felt confident approaching their summative OSCEs. Educators enjoyed the opportunity to develop their teaching skills, citing mutual benefit and gratitude to past peer-educators as strong motivators to teach others. CONCLUSIONS: Near-peer education, valued by near-peer learners and teachers alike, was a useful method to improve preparation and perceived performance in summative examinations. In particular, a novel year-long, student-run initiative was regarded as a valuable and feasible adjunct to faculty teaching.

Impact of different etiologies of bronchiectasis on the pulmonary function tests.

BACKGROUND: Bronchiectasis develops along the natural course of several respiratory and systemic conditions and induces significant changes in the morphofunctional structure of airways. Our objective was to assess the impact of various causes of bronchiectasis on clinical data, pulmonary function tests, and high-resolution computed tomography (HRCT). METHODS: The present report was a cross-sectional study that was conducted with 112 consecutive patients with bronchiectasis, who were allocated to five groups, as follows: sequelae of tuberculosis, history of non-tuberculosis infection, cystic fibrosis (CF), primary ciliary dyskinesia (PCD), and rheumatoid arthritis. All of the participants underwent spirometry, whole-body plethysmography, measurement of the diffusing capacity for carbon monoxide (DLco), and HRCT. RESULTS: The highest HRCT score was exhibited in patients with CF (6.03 ± 1.03). The values of forced expiratory volume in 1 second (FEV1) (52.2 ± 17.7%) and DLco (74.1 ± 15.2%) were lower in patients with sequelae of tuberculosis. The increase in the residual volume was more accentuated in the patients with CF (193.5 ± 39.5%) and PCD (189 ± 36.4%). By the multivariate analysis, the cause of FEV1 and bronchiectasis, HRCT score, and degree of dyspnea behaved as independent predictors of DLco. CONCLUSION: In individuals with bronchiectasis, the pulmonary function abnormalities are associated with the etiology of the underlying disease.
