      Tierney, Emma; Kirthi, Shivashini; Ramsay, Bart; Ahmad, Kashif (JAAD Case Reports, 2019-03-01)
      Drug-induced lupus erythematosus (DILE) is a lupus-like syndrome temporally related to continuous drug exposure. DILE can be divided into systemic lupus erythematosus (SLE), subacute cutaneous lupus erythematosus (SCLE) and chronic cutaneous lupus.1 Hydrochlorothiazide was the first drug associated with SCLE in 1985,2 but at least 100 other agents have since been reported to induce/exacerbate SCLE, with terbinafine, tumor necrosis factor (TNF)-α inhibitors, antiepileptics, and proton pump inhibitors, the most frequently associated medications. We present a case of ustekinumab-induced SCLE in a patient being treated for psoriasis.
    • Pulmonary aspiration in preschool children with cystic fibrosis.

      Clarke, D; Gorman, I; Ringholz, F; McDermott, M; Cox, D W; Greally, P; Linnane, B; Mc Nally, P (Respiratory Research, 2018-12-17)
      Pulmonary aspiration of gastric refluxate (PAGR) has been demonstrated in association with pulmonary inflammation in school aged children with Cystic Fibrosis (CF). We sought to determine if similar findings were present in preschool children. Pepsin was measured in Broncho-alveolar lavage (BAL) fluid collected from clinically stable preschool children with CF and controls. Elevated pepsin levels were found in a subgroup of children with CF, but this was not found to be associated with pulmonary infection, pulmonary inflammation or respiratory or gastrointestinal symptoms.
    • Erectile Dysfunction and Ischaemic Heart Disease.

      Ibrahim, Abdalla; Ali, Mohamed; Kiernan, Thomas J; Stack, Austin G (European Cardiology Review, 2018-12-01)
      Erectile dysfunction (ED) is a common disorder that affects the quality of life of many patients. It is prevalent in more than half of males aged over 60 years. Increasing evidence suggests that ED is predominantly a vascular disorder. Endothelial dysfunction seems to be the common pathological process causing ED. Many common risk factors for atherosclerosis such as diabetes, hypertension, smoking, obesity and hyperlipidaemia are prevalent in patients with ED and so management of these common cardiovascular risk factors can potentially prevent ED. Phosphodiesterase type 5 inhibitors provide short-term change of haemodynamic factors to help initiate and maintain penile erection. They have been shown to be an effective and safe treatment strategy for ED in patients with heart disease, including those with ischaemic heart disease and hypertension.

    • Annular Rupture During Transcatheter Aortic Valve Implantation: Predictors, Management and Outcomes.

      Coughlan, J J; Kiernan, Thomas; Mylotte, Darren; Arnous, Samer (International Cardiology Review, 2018-09-01)
      Transcatheter aortic valve implantation (TAVI) is the treatment of choice in patients with symptomatic severe aortic stenosis who are either inoperable or at high risk for conventional surgical aortic valve replacement. Recent data have also shown favourable outcomes in patients deemed to be at intermediate operative risk, which expands the application of this novel technology. Despite its success, TAVI has been associated with rare life-threatening complications. Of these, aortic annular rupture is considered to be the most devastating. Advances in pre-procedural screening and patient selection have reduced the incidence of annular rupture. When this complication occurs, early recognition and prompt management are essential. This article is intended to provide a comprehensive review of the predictors, management and clinical outcomes of aortic annular rupture.
    • Temporal trends in acute kidney injury across health care settings in the Irish health system: a cohort study.

      Stack, Austin G; Li, Xia; Kaballo, Mohamed; Elsayed, Mohamed E; Johnson, Howard; Murray, Patrick T; Saran, Rajiv; Browne, Leonard D (Nephrology, dialysis, transplantation, 2018-08-07)
      Complete ascertainment of the true rates of acute kidney injury (AKI) and emerging trends are essential for planning of preventive strategies within health systems. We conducted a retrospective cohort study from 2005 to 2014 using data from regional laboratory information systems to determine incidence rates of AKI and severity Stages 1-3 in the Irish health system. Multivariable models were developed to explore annual trends and the contributions of demographic factors, clinical measures, geographic factors and location of medical supervision expressed as adjusted odds ratios (ORs) and 95% confidence intervals (CIs). From 2005 to 2014, incidence rates of AKI increased from 6.1% (5.8-6.3) to 13.2% (12.7-13.8) per 100 patient-years in men and from 5.0% (4.8-5.2) to 11.5% (11.0-12.0) in women, P < 0.001. Stage 1 AKI accounted for the greatest growth in incidence, from 4.4% (95% CI 4.3-4.6) in 2005 to 10.1% (95% CI 9.8-10.5) in 2014 (P < 0.001 for trend). Compared with 2005, patients in 2014 were more likely to experience AKI [OR 4.53 (95% CI 4.02-5.1) for Stage 1, OR 5.22 (4.16-6.55) for Stage 2 and OR 4.11 (3.05-5.54) for Stage 3], adjusting for changing demographic and clinical profiles. Incidence rates of AKI increased in all locations of medical supervision during the period of observation, but were greatest for inpatient [OR 19.11 (95% CI 17.69-20.64)] and emergency room settings [OR 5.97 (95% CI 5.56-6.42)] compared with a general practice setting (referent). Incidence rates of AKI have increased substantially in the Irish health system, which were not accounted for by changing demographic patterns, clinical profiles or location of medical supervision.

    • Prevalence and correlates of central venous catheter use among haemodialysis patients in the Irish health system - a national study.

      Hussein, Wael F; Mohammed, Husham; Browne, Leonard; Plant, Liam; Stack, Austin G (BMC Nephrology, 2018-04-02)
      Central venous catheters (CVC) are associated with substantial morbidity and mortality among patients undergoing haemodialysis (HD), yet they are frequently used as the primary vascular access for many patients on HD. The goal of this study was to determine the prevalence and variation in CVC use across centres in the Irish health system. Data from the National Kidney Disease Clinical Patient Management System (KDCPMS) was used to determine CVC use and patterns across centres. Data on demographic characteristics, primary cause of end-stage kidney disease (ESKD), comorbid conditions, laboratory values and centre affiliation were extracted for adult HD patients (n = 1, 196) who were on dialysis for at least three months up to end of December 2016. Correlates of CVC use were explored using multivariable logistic regression. Overall prevalence of CVC use was 54% and varied significantly across clinical sites from 43% to 73%, P < 0.001. In multivariate analysis, the likelihood of CVC use was lower with increasing dialysis vintage, OR 0.40 (0.26-0.60) for 4 years vs 1 year vintage, rising serum albumin, OR 0.73 (0.59-0.90) per 5 g/L), and with cystic disease as a cause of ESKD, OR 0.38 (95% CI 0.21-0.6). In contrast, catheter use was greater for women than men, OR 1.77 (1.34-2.34) and for 2 out of 10 regional dialysis centres, OR 1.98 (1.02-3.84) and OR 2.86 (1.67-4.90) respectively compared to referent group). Catheters are the predominant type of vascular access in patients undergoing HD in the Irish health system. Substantial centre variation exists which is not explained by patient-level characteristics.
    • Saving Blood and Reducing Costs: Updating Blood Transfusion Practice in Lower Limb Arthroplasty

    • A Comparison of Perceived and Measured Paternal Weight and BMI, and Relationship to Weight and BMI of his Children

      Power, RF; Power, B; O’Gorman, CS (Irish Medical Journal, 2018-02)
      Nineteen percent of 9 years old Irish children are overweight; seven percent are obese. Our aims were: to examine whether differences exist between paternal self-reported and measured height, weight and BMI in a population representative sample; and to explore paternal perceptions of their own weight status. Measures of height and weight for fathers and for their children from the National Longitudinal Study of Children Growing Up in Ireland were obtained using validated methods. Three quarters of fathers (6,263 of 8,568 study children) with a mean age of 42 years (SD 5.04) responded. The mean difference between self-reported and measured weight was -1.03kg (SD=4.52), indicating that weight was underestimated. Obese fathers were more likely to have an obese son (9.4% compared to 5.3% for the full cohort) and an obese daughter (12.4% compared to 7.7%). These data suggest that there is a strong relationship between fathers' weights and his childrens’ weights. A leading factor in the development of childhood obesity is parental obesity. Targeting overweight and obesity in the child should occur simultaneously with tackling overweight and obesity in the parents; in this study, the fathers
    • Temporal trends in hyperuricaemia in the Irish health system from 2006-2014: A cohort study.

      Kumar A U, Arun; Browne, Leonard D; Li, Xia; Adeeb, Fahd; Perez-Ruiz, Fernando; Fraser, Alexander D; Stack, Austin G; University Hospital Limerick (PLOS ONE, 2018-01-01)
      Elevated serum uric acid (sUA) concentrations are common in the general population and are associated with chronic metabolic conditions and adverse clinical outcomes. We evaluated secular trends in the burden of hyperuricaemia from 2006-2014 within the Irish health system. Data from the National Kidney Disease Surveillance Programme was used to determine the prevalence of elevated sUA in adults, age > 18 years, within the Irish health system. Hyperuricaemia was defined as sUA > 416.4 μmol/L in men and > 339.06 μmol/L in women, and prevalence was calculated as the proportion of patients per year with mean sUA levels above sex-specific thresholds. Temporal trends in prevalence were compared from 2006 to 2014 while general estimating equations (GEE) explored variation across calendar years expressed as odds ratios (OR) and 95% Confidence intervals (CI). From 2006 to 2014, prevalence of hyperuricaemia increased from 19.7% to 25.0% in men and from 20.5% to 24.1% in women, P<0.001. The corresponding sUA concentrations increased significantly from 314.6 (93.9) in 2006 to 325.6 (96.2) in 2014, P<0.001. Age-specific prevalence increased in all groups from 2006 to 2014, and the magnitude of increase was similar for each age category. Adjusting for baseline demographic characteristics and illness indicators, the likelihood of hyperuricemia was greatest for patients in 2014; OR 1.45 (1.26-1.65) for men and OR 1.47 (1.29-1.67) in women vs 2006 (referent). Factors associated with hyperuricaemia included: worsening kidney function, elevated white cell count, raised serum phosphate and calcium levels, elevated total protein and higher haemoglobin concentrations, all P<0.001. The burden of hyperuricaemia is substantial in the Irish health system and has increased in frequency over the past decade. Advancing age, poorer kidney function, measures of nutrition and inflammation, and regional variation all contribute to increasing prevalence, but these do not fully explain emerging trends.
    • Hemorrhagic lesion on the chest wall after trauma.

      Roche, Lisa; Wall, Dmitri; Hackett, Catriona (JAAD case reports, 2018-01)
      A 59-year-old woman presented with a burning, rapidly progressive mass on the midchest, occurring after a fall, 4 months prior. Examination found a large well-circumscribed mass over the lower xiphisternum (Figs 1 and 2). Results of baseline investigations were normal apart from mildly elevated liver function values. A computerized tomography scan confirmed a 6.4- x 4.9-cm lobulated soft tissue heterogeneous-density mass located in the subcutaneous fat with ill-defined borders and no obvious infiltration of the chest wall. A single focal abnormality was noted in the liver. Several incision/drainage procedures were complicated by difficulty achieving hemostasis. Ellipse incisional biopsy was performed (Figs 3 and 4).
    • Determination of the Lung Clearance Index (LCI) in a Paediatric Cystic Fibrosis Cohort

      Mulligan, M; Collins, L; Dunne, CP; Keane, L; Linnane, B (Irish Medical Journal, 2017-10)
      The pathogenesis of CF lung disease may start in infancy. Therefore, it is important to monitor the early stages of its progress. The Exhalyzer D is the first commercially available device designed to measure lung ventilation inhomogeneity at any age. This study was conducted to assess the performance and feasibility of using the Exhalyzer D in a paediatric CF clinic. A total of 91 subjects were recruited (23 controls, and 68 patients with CF). The majority of CF patients (79%) and controls (78%) completed at least two successful washouts. A strong linear correlation was noted between LCI and FEV1. Children with CF under six years of age struggled to perform the washout in a technically correct manner. A clear learning effect was observed, with improved technique and shorter testing times on repeated visits.
    • An unusual case of recurrent chest infections.

      Dahab, Taqua; Saleem, Shahzaib; Gumani, Dikshaini; Casserly, Brian; Sharkey, Claire; Laghi, Frank; Newmarch, William (2017-08)
      This case presentation relates to a 53 year old male, cachectic in appearance, who presented with progressively worsening dyspnoea, cough, intermittent haemoptysis and a history of nasal dryness ongoing over five months. The patient had received multiple courses of oral antibiotics for suspected community acquired pneumonia with no significant improvement. He was referred to our Respiratory Department for further evaluation of his symptoms. His HRCT showed right middle lobe consolidation with central cavitations. Furthermore, the transbronchial biopsy had been performed and the cytological examination revealed lipid laden macrophage with interstitial inflammatory changes. With return to the patient over the counter drug history, he described the frequent use of petroleum jelly to alleviate the symptoms of nasal dryness. This is the first report case of exogenous lipoid pneumonia presented with haemoptysis and cavitations in the HRCT.
    • Comparing cardiovascular risk factors, disease and treatment in participants with rheumatoid arthritis and without arthritis in a population based study

      O’Driscoll, N; Kennedy, N; Anjum, S; Fraser, A; Hannigan, A (Irish Medical Journal, 2017-05)
      Rheumatoid Arthritis (RA) is associated with a significant increase in mortality compared to the general population, with cardiovascular disease (CVD) the leading cause of death. The aim of this study is to compare the prevalence and treatment of modifiable CV risk factors and history of CVD in those with RA and those without arthritis in Ireland. Data from the Irish Longitudinal Study on Ageing (TILDA), a population-representative cohort study of people in Ireland aged 50 or over, was used. Participants with RA (n=457) were twice as likely to be obese (OR 2.02, 95% CI 1.99 to 2.06) compared to those without arthritis (n=4,063). Participants with RA were also more likely to be physically inactive (OR 1.73, 95% CI 1.69 to 1.76) and taking antihypertensive medication than those without arthritis. Exercise can have a beneficial impact on CVD and specific interventions to increase physical activity in those with RA may be warranted
