Infestation of the human by the parasitic scabies mite, Sarcoptes scabiei var hominis, is discussed in this chapter on scabies. The life cycle of the mite is outlined, and the epidemiology and modes of transmission are discussed. The clinical presentations of classical scabies, crusted scabies, scabies in someone with HIV, and scabies incognito are all explained in turn. Diagnosis is discussed and first-line management with permethrin, with malathion as a second-line alternative, are explained. The accompanying practical advice on how to use the treatments that should be given to patients is detailed. The treatment of crusted scabies, considerations in pregnancy/breastfeeding, and emerging resistance are mentioned.

Abstract Background Iron deficiency anaemia in pregnancy (IDAP) affects 11–18% of Australian pregnancies and is associated with adverse perinatal outcomes. National prescribing data suggests the use of intravenous iron in pregnancy is increasingly common. This study aimed to: 1) Establish the current patterns of intravenous iron use by Fellows of the Royal Australian and New Zealand College of Obstetricians (FRANZCOG) when treating iron deficiency and IDAP including immediately postpartum and; 2) Assess FRANZCOG opinions regarding potential trial of intravenous iron for first-line treatment of IDAP. Methods An online survey of RANZCOG Fellows practicing obstetrics was distributed in September 2018. Results were analysed descriptively and responses compared by clinician demographics using Chi-squared testing. Results Of 484 respondents (21% of FRANZCOG), 457 were currently practicing obstetrics. Most prescribed intravenous iron in pregnancy (96%) and/or postpartum (85%). Most intravenous iron was prescribed for IDAP (98%) rather than iron deficiency without anaemia (53%), and for IDAP most commonly second-line to failed oral iron supplementation and first-line in special circumstances (59%). Intravenous iron prescribing was associated with shorter time since FRANZCOG completion (p = 0.01), public hospital practice (p = 0.008) and higher hospital birth numbers (p = 0.01). Most respondents (90%) would consider a randomised controlled trial of first-line intravenous iron for IDAP, although views on appropriate thresholds differed. Conclusions Almost all respondents prescribed intravenous iron for IDAP, and while mostly used for second-line treatment over half sometimes used it first-line. With accelerating intravenous iron use, further research is required into its optimal use in pregnancy, recognizing important clinical outcomes and cost effectiveness.

Crusted Scabies

ABSTRACT Scabies, a parasitic skin infestation by the burrowing “itch” mite Sarcoptes scabiei, causes significant health problems for children and adults worldwide. Crusted scabies is a particularly severe form of scabies in which mites multiply into the millions, causing extensive skin crusting. The symptoms and signs of scabies suggest host immunity to the scabies mite, but the specific resistant response in humans remains largely uncharacterized. We used 4 scabies mite recombinant proteins with sequence homology to extensively studied house dust mite allergens to investigate a differential immune response between ordinary scabies and the debilitating crusted form of the disease. Subjects with either disease form showed serum IgE against recombinant S. scabiei cysteine and serine proteases and apolipoprotein, whereas naive subjects showed minimal IgE reactivity. Significantly (P < 0.05) greater serum IgE and IgG4 binding to mite apolipoprotein occurred in subjects with crusted scabies than in those with ordinary scabies. Both subject groups showed strong proliferative responses (peripheral blood mononuclear cells) to the scabies antigens, but the crusted scabies group showed increased secretion of the Th2 cytokines interleukin 5 (IL-5) and IL-13 and decreased Th1 cytokine gamma interferon (IFN-γ) in response to the active cysteine protease. These data confirm that a nonprotective allergic response occurs in the crusted disease form and demonstrate that clinical severity is associated with differences in the type and magnitude of the antibody and cellular responses to scabies proteins. A quantitative IgE inhibition assay identified IgE immunoreactivity of scabies mite antigens distinct from that of house dust mite antigens, which is potentially important for specific scabies diagnosis and therapy.

Abstract. This contribution consists of a critical review of the literature about the articulation of two traditionally separated theoretical fields: social representations and commitment. Besides consulting various works and communications, a bibliographic search was carried out (between February and December, 2016) on various databases using the keywords “commitment” and “social representation,” in the singular and in the plural, in French and in English. Articles published in English or in French, that explicitly made reference to both terms, were included. The relations between commitment and social representations are approached according to two approaches or complementary lines. The first line follows the role of commitment in the representational dynamics: how can commitment transform the representations? This articulation gathers most of the work on the topic. The second line envisages the social representations as determinants of commitment procedures: how can these representations influence the effects of commitment procedures? This literature review will identify unexploited tracks, as well as research perspectives for both areas of research.

Bislang steht für Patienten mit metastasiertem kastrationsresistentem Prostatakarzinom (mCRPC), die auf die Standard-First-line-Chemotherapie mit Docetaxel nicht mehr adäquat ansprechen, keine Evidenz-basierte Therapieoption zur Verfügung. Große Hoffnungen verbinden sich daher mit Cabazitaxel, einer neuen Substanz, die diesen Patienten noch einmal die Chance auf eine Überlebenszeitverlängerung bietet. In den USA ist Cabazitaxel bereits für die Second-line-Behandlung beim mCRPC nach Docetaxel-Versagen zugelassen. In Europa ist die Zulassung für diese Indikation bean-tragt.

Endothelial Growth Factor

A large proportion of patients with metastatic colorectal cancer (mCRC) experience disease progression after first-line treatment with chemotherapy and bevacizumab, an anti-angiogenic agent, as a result of acquired resistance. However, blocking angiogenesis by targeted therapy towards the vascular endothelial growth factor (VEGF) pathway still forms an essential part of the second-line treatment strategy. Although three approved evidence-based choices for angiogenic agents (continuing treatment with bevacizumab, ramucirumab and aflibercept) are currently available in the second line, making the most effective choice is challenging due to the lack of studies directly comparing these agents. Moreover, despite huge investigational efforts, no predictive biomarker for anti-angiogenic cancer therapies could be identified so far.

Significant Difference

Background: Pre-treated patients with first-line treatment can be offered a second treatment with the aim of improving their poor clinical prognosis. The therapy of metastatic colorectal cancer (CRC) patients who did not respond to first-line therapy has limited treatment options. Recently, many studies have paid much attention to the efficacy of bevacizumab as an adjuvant treatment for metastatic colorectal cancer. Objectives: We aimed to evaluate the efficacy and toxicity of bevacizumab plus chemotherapy compared with bevacizumab-naive based chemotherapy as second-line treatment in people with metastatic CRC. Methods: Electronic databases were searched for eligible studies updated to March 2018. Randomized-controlled trials comparing addition of bevacizumab to chemotherapy without bevacizumab in MCRC patients were included, of which, the main interesting results were the efficacy and safety profiles of the addition of bevacizumab in patients with MCRC as second-line therapy. Result: Five trials were eligible in the meta-analysis. Patients who received the combined bevacizumab and chemotherapy treatment in MCRC as second-line therapy showed a longer overall survival (OS) (OR=0.80,95%CI=0.72-0.89, P<0.0001) and progression-free survival (PFS) (OR=0.69,95%CI=0.61-0.77, P<0.00001). In addition, there was no significant difference in objective response rate (ORR) (RR=1.36,95%CI=0.82-2.24, P=0.23) or severe adverse event (SAE) (RR=1.02,95%CI=0.88-1.19, P=0.78) between bevacizumab-based chemotherapy and bevacizumabnaive based chemotherapy. Conclusion: Our results suggest that the addition of bevacizumab to the chemotherapy therapy could be an efficient and safe treatment option for patients with metastatic colorectal cancer as second-line therapy and without increasing the risk of an adverse event.

Abstract Background Immediate hypersensitivity reaction to ursodiol is rare and there is no previously published protocol on ursodiol desensitization. Case presentation A 59-year-old woman with primary biliary cholangitis (PBC) developed an immediate hypersensitivity reaction to ursodiol—the first-line treatment for PBC. When she switched to a second-line treatment, her PBC continued to progress. As such, she completed a novel 12-step desensitization protocol to oral ursodiol. She experienced recurrent pruritus after each dose following desensitization, which subsided after a month of being on daily ursodiol. Conclusion Immediate hypersensitivity reaction to ursodiol is uncommon. Our case demonstrated that this novel desensitization protocol to ursodiol could be safely implemented when alternative options are not available or have proven inferior in efficacy.
