Hip Int 2018 Nov;28(2_suppl):35-42

3 IRCCS Istituto Ortopedico Galeazzi, Hip Department, Milan, Italy.

Introduction:: Failures due to adverse reaction to metal debris (ARMD) have become an area of common focus among surgeons performing hip replacements. Several authors have reported data on the prevalence of these masses, in both symptomatic and asymptomatic patients after either large-diameter head metal-on-metal (MoM) total hip arthroplasty (THA) or hip resurfacing arthroplasty, with a large variability of rate. To our knowledge, few data are reported on the association of this lesion with the use of small-head diameter MoM. Read More

Skin tests are important in children with β-lactam hypersensitivity, but may be reduced in number.

Pediatr Allergy Immunol 2019 Feb 7. Epub 2019 Feb 7.

Allergy Unit, Département de Pneumologie et Addictologie, Hôpital Arnaud de Villeneuve, CHU de Montpellier, Univ Montpellier, France.

There is no perfect agreement on how to perform an allergy work-up in suspected beta-lactam (BL) allergic children, since skin test (ST)-induced pain is often a limitation. The aim of the study was to assess the possibility of reducing the number of ST in children when performing a complete allergy work-up for BL hypersensitivity reactions. A retrospective analysis of all patients referring to the Allergy Unit of the University Hospital of Montpellier (France) with positive responses in immediate- and non-immediate-reading ST to a BL over a 16-years period was performed, to determine the positive predictive value (PPV) of ST.

The Inflammatory Effects of Breast Implant Particulate Shedding: Comparison With Orthopedic Implants.

Aesthet Surg J 2019 Jan;39(Supplement_1):S36-S48

Department of Orthopedic Surgery, Rush University Medical Center, Chicago, IL.

Currently, there is a dearth of information regarding the degree of particle shedding from breast implants (BIs) and what are the general biological consequences of BI debris. Thus, it is unclear to what degree BI debris compromises the long-term biological performance of BIs. For orthopedic implants, it is well established that the severity of biological reactivity to implant debris governs long-term clinical performance. Read More

Operational immune tolerance towards transplanted allogeneic pancreatic islets in mice and a non-human primate.

Diabetologia 2019 Jan 31. Epub 2019 Jan 31.

Diabetes Research Institute and Cell Transplant Center, University of Miami Miller School of Medicine, 1450 NW 10th Ave, Miami, FL, 33136, USA.

Aims/hypothesis: Patients with autoimmune type 1 diabetes transplanted with pancreatic islets to their liver experience significant improvement in quality of life through better control of blood sugar and enhanced awareness of hypoglycaemia. However, long-term survival and efficacy of the intrahepatic islet transplant are limited owing to liver-specific complications, such as immediate blood-mediated immune reaction, hypoxia, a highly enzymatic and inflammatory environment and locally elevated levels of drugs including immunosuppressive agents, all of which are injurious to islets. This has spurred a search for new islet transplant sites and for innovative ways to achieve long-term graft survival and efficacy without life-long systemic immunosuppression and its complications.

Rotavirus Double Infection Model to Study Preventive Dietary Interventions.

Nutrients 2019 Jan 10;11(1). Epub 2019 Jan 10.

Departament de Bioquímica i Fisiologia, Facultat de Farmàcia i Ciències de l'Alimentació, University of Barcelona (UB), Av. Joan XXIII 27-31, 08028 Barcelona, Spain.

Rotaviruses are the main cause of acute diarrhea among young children worldwide with an increased frequency of reinfection. Several life style factors, such as dietary components, may influence such processes by affecting the outcome of the first rotavirus infection and therefore having a beneficial impact on the anti-rotavirus immune responses during any subsequent reinfections. The aim of this research was to develop a double-infection model in rat that mimics real-life clinical scenarios and would be useful in testing whether nutritional compounds can modulate the rotavirus-associated disease and immune response.

Nat Commun 2019 01 8;10(1):87. Epub 2019 Jan 8.

The Wellcome Trust and Cancer Research UK Gurdon Institute and Department of Biochemistry, University of Cambridge, Tennis Court Road, Cambridge, CB2 1QN, UK.

Mutations in the ATM tumor suppressor gene confer hypersensitivity to DNA-damaging chemotherapeutic agents. To explore genetic resistance mechanisms, we performed genome-wide CRISPR-Cas9 screens in cells treated with the DNA topoisomerase I inhibitor topotecan. Thus, we here establish that inactivating terminal components of the non-homologous end-joining (NHEJ) machinery or of the BRCA1-A complex specifically confer topotecan resistance to ATM-deficient cells.

The role of biologics in the treatment of chronic granuloma annulare.

Int J Dermatol 2019 Jan 7. Epub 2019 Jan 7.

David Geffen School of Medicine at University of California, Los Angeles, CA, USA.

Background: Granuloma annulare (GA), a benign inflammatory skin disease, is considered a Th1-type delayed hypersensitivity reaction. Localized GA is likely to resolve spontaneously, whereas disseminated GA (DGA) may persist for decades and can be resistant to treatment. Biologics including TNF-α inhibitors have been proposed and utilized as salvage therapy for GA and other related diseases, interstitial granulomatous dermatitis (IGD), and actinic granuloma (AG).

Direct oral amoxicillin challenge without preliminary skin testing in adult patients with allergy and at low risk with reported penicillin allergy.

Allergy Asthma Proc 2019 Jan;40(1):57-61

Department of Internal Medicine, Emory University, Atlanta, Georgia.

Ten percent of hospitalized patients report penicillin allergy; however, recent studies indicate that ∼98% of these patients are not acutely hypersensitive. Unconfirmed penicillin allergy poses public health risks, and an evaluation of penicillin allergy labels is recommended to improve antibiotic stewardship. Although the most widely accepted protocol is penicillin skin testing, followed by oral amoxicillin challenge, time constraints and resources may preclude this. Read More

Treatment with methyl-β-cyclodextrin prevents mechanical allodynia in resiniferatoxin neuropathy in a mouse model.

Biol Open 2019 Jan 14;8(1). Epub 2019 Jan 14.

Department of Anatomy, School of Medicine, College of Medicine, Kaohsiung Medical University, Kaohsiung 80708, Taiwan

Specialized microdomains which have cholesterol-rich membrane regions contain transient receptor potential vanilloid subtype 1 (TRPV1) are involved in pain development. Our previous studies have demonstrated that the depletion of prostatic acid phosphatase (PAP) - a membrane-bound ectonucleotidase -- and disordered adenosine signaling reduce the antinociceptive effect. The role of membrane integrity in the PAP-mediated antinociceptive effect in small-fiber neuropathy remains unclear, especially with respect to whether TRPV1 and PAP are colocalized in the same microdomain which is responsible for PAP-mediated antinociception.

Controversies in drug allergy: Testing for delayed reactions.

J Allergy Clin Immunol 2019 Jan 17;143(1):66-73. Epub 2018 Dec 17.

Dermatology and Allergy Department, Tenon Hospital, Medecine Sorbonne University, Paris, France; Assistance publique-hopitaux de Paris, Paris, France.

Controversies exist with regard to in vivo approaches to delayed immunologically mediated adverse drug reactions, such as exanthem (maculopapular eruption), drug reaction with eosinophilia and systemic symptoms, acute generalized exanthematous pustulosis, Stevens-Johnson syndrome/toxic epidermal necrolysis, and fixed drug eruptions. In particular, widespread differences exist between regions and practice on the availability and use of intradermal and patch testing, the standard drug concentrations used, the use of additional drugs in intradermal and patch testing to help determine cross-reactivity, the timing of testing in relation to the occurrence of the adverse drug reaction, the use of testing in specific phenotypes, and the use of oral challenge in conjunction with delayed intradermal and patch testing to ascertain drug tolerance. It was noted that there have been advances in the science of delayed T cell-mediated reactions that have shed light on immunopathogenesis and provided a mechanism of preprescription screening in the case of HLA-B*57:01 and abacavir hypersensitivity and HLA-B*15:02 and carbamazepine Stevens-Johnson syndrome/toxic epidermal necrolysis in Southeast Asian subjects.

Systemic Treatments for Allergic Contact Dermatitis.

Dermatitis 2019 Jan/Feb;30(1):46-53

Department of Dermatology, Loma Linda University, CA.

Allergic contact dermatitis is a common disease within the family of delayed-type hypersensitivity reactions. In more severe cases of allergic contact dermatitis, topical steroids may prove insufficient, and systemic therapeutic agents are often used. Even when systemic therapies such as cyclosporine lead to improvement, withdrawal of these agents is challenging and can lead to undesirable morbidities. Read More
