MATERIALS AND METHODS: An African statue belonging to the African Yoruba culture has been analysed. RESULTS: Members of Ogboni Society in Yoruba culture used this statues to represent a real subject and to communicate between the living and dead. CONCLUSION: The statue reported seems to represent a case of real goiter.

Update on the safety profile of certolizumab pegol in rheumatoid arthritis: an integrated analysis from clinical trials.

OBJECTIVE: To report the long-term safety data of certolizumab pegol (CZP) in rheumatoid arthritis (RA) accumulated as of 30 November 2011. DESIGN: Data from 10 completed randomised controlled trials (RCT) of CZP in RA and several open-label extensions (OLE) were pooled across all doses. Reported adverse events (AE) occurred between the first dose and 84 days after the last dose. All deaths, serious infectious events (SIE) and malignancies were reviewed by external experts, classified according to predefined rules, and validated by an external steering committee. Incidence rates (IR) and event rates (ER) per 100 patient-years (PY) are presented. RESULTS: 4049 RA patients who received CZP were included in the safety pooling; total exposure 9277 PY, mean exposure 2.1 years (range 0.04-7.6). SIE, most frequently pneumonia (IR 0.73/100 PY), were the most common serious AE, occurring more frequently in CZP compared to placebo-treated patients in RCT (IR 5.61/100 PY vs 1.35/100 PY, odds ratio (OR) 4.35, 95% CI 0.65 to 29.30). SIE rates were lower in the CZP-treated population including OLE (ER 4.33/100 PY). 44 patients developed tuberculosis (IR 0.47/100 PY), 39 from high endemic regions. 58 deaths occurred in CZP-exposed patients (IR 0.63/100 PY) and 70 developed malignancies excluding non-melanoma skin cancer (IR 0.76/100 PY), including five lymphomas (IR 0.05/100 PY). CONCLUSIONS: No new or unexpected safety signals associated with CZP emerged in this updated long-term safety analysis. While SIE rates were higher for CZP than for placebo in RCT, the rate decreased with continued exposure to CZP. These rates are consistent with data previously reported for CZP and other tumour necrosis factor inhibitors.

Opportunistic infections and biologic therapies in immune-mediated inflammatory diseases: consensus recommendations for infection reporting during clinical trials and postmarketing surveillance.

No consensus has previously been formed regarding the types and presentations of infectious pathogens to be considered as 'opportunistic infections' (OIs) within the setting of biologic therapy. We systematically reviewed published literature reporting OIs in the setting of biologic therapy for inflammatory diseases. The review sought to describe the OI definitions used within these studies and the types of OIs reported. These findings informed a consensus committee (infectious diseases and rheumatology specialists) in deliberations regarding the development of a candidate list of infections that should be considered as OIs in the setting of biologic therapy. We reviewed 368 clinical trials (randomised controlled/long-term extension), 195 observational studies and numerous case reports/series. Only 11 observational studies defined OIs within their methods; no consistent OI definition was identified across studies. Across all study formats, the most numerous OIs reported were granulomatous infections. The consensus group developed a working definition for OIs as 'indicator' infections, defined as specific pathogens or presentations of pathogens that 'indicate' the likelihood of an alteration in host immunity in the setting of biologic therapy. Using this framework, consensus was reached upon a list of OIs and case-definitions for their reporting during clinical trials and other studies. Prior studies of OIs in the setting of biologic therapy have used inconsistent definitions. The consensus committee reached agreement upon an OI definition, developed case definitions for reporting of each pathogen, and recommended these be used in future studies to facilitate comparison of infection risk between biologic therapies.

Repeated change-of-direction test for collegiate male soccer players.

AIM: The aim of the study was to investigate the applicability of a repeated change-of-direction (RCoD) test for NCAA Division-I male soccer players. METHODS: The RCoD test consisted of 5 diagonal direction changes per repetition with a soccer ball to be struck at the end. Each player performed 15 repetitions with approximately 10 seconds to jog back between repetitions. Data were collected in two sessions. In the first session, 13 players were examined for heart rate responses and blood lactate concentrations. In the second session, 22 players were examined for the test's ability to discriminate the primary from secondary players (78.0±16.1 and 10.4±13.3 minutes per match, respectively). RESULTS: Heart rate data were available only from 9 players due to artifacts. The peak heart rate (200.2±6.6 beats∙min-1: 99.9±3.0% maximum) and blood lactate concentration (14.8±2.4 mmol∙L-1 immediately after) resulted in approximately 3.5 and 6.4-fold increases from the resting values, respectively. These values appear comparable to those during intense periods of soccer matches. In addition, the average repetition time of the test was found to discriminate the primary (4.85±0.23 s) from the secondary players (5.10±0.24 s) (P=0.02). CONCLUSION: The RCoD test appears to induce physiological responses similar to intense periods of soccer matches with respect to heart rate and blood lactate concentration. Players with better average repetition times tend to be those who play major minutes.

High-dose chemotherapy in relapsed or refractory Hodgkin lymphoma patients: a reappraisal of prognostic factors.

High-dose chemotherapy (HDCT) has a consolidated role in the treatment of patients with refractory or relapsed Hodgkin lymphoma (HL). We report clinical results of 97 HL patients who underwent HDCT for refractory (62 patients) or relapsed (35 patients) diseases in Istituto Europeo di Oncologia, from 1995 to 2009. Treatment included high-dose carmustine, etoposide, cytarabine and melphalan in 84 patients and high-dose idarubicin and melphalan in 13 patients with subsequent peripheral hemopoietic stem cells transplant. Outcomes were evaluated in terms of progression-free survival (PFS) and overall survival (OS). In order to identify prognostic factors for outcome, a multivariate analysis for age, sex, disease status (refractory/relapsed), disease stage, B symptoms, presence of extranodal involvement, bulky disease, elevated lactate dehydrogenase, number of previous chemotherapy lines, remission status before transplant, 18F-fluoro-deoxy-d-glucose positron emission tomography ((18) FDG-PET) status before and after transplant was done. A clinical response was achieved in 91% of patients, with complete remissions in 76/97 patients. With a median follow-up of 45 months (range 1-164 months), 5-year PFS and OS were 64% and 71%, respectively. Remission status after induction therapy, 18F-fluoro-deoxy-d-glucose positron emission tomography status before and after transplant were the most important prognostic factors for PFS and OS in univariate or multivariate analyses. HDCT is able to induce a high remission rate and a prolonged PFS in more than 50% of the patients with refractory and relapsed HL.

The Intersection of COVID-19 and Autoimmunity: What is Our Current Understanding?

Viral infections have historically had a complex relationship with autoimmune diseases. For patients with preexisting autoimmune disorders, often complicated by immunosuppressive therapies, there are numerous potential effects of COVID-19, a disease of complex immunobiology, including the potential for an altered natural history of COVID-19 when infected. In addition, individuals without recognized autoimmune disease may be vulnerable to virally induced autoimmunity in the forms of autoantibody formation, as well as the development of clinical immune-mediated inflammatory diseases. Until quite recently in the pandemic, this relationship between COVID-19 and autoimmune diseases has been relatively underexplored; yet such investigation offers potential insights into immunopathogenesis as well as for the development of new immune-based therapeutics. Our review examines this relationship through exploration of a series of questions with relevance to both immunopathogenic mechanisms as well as some clinical implications.

Primary follicular and marginal-zone lymphoma of the breast: clinical features, prognostic factors and outcome: a study by the International Extranodal Lymphoma Study Group.

BACKGROUND: Primary breast lymphoma (PBL) of low-grade histology is a rare disease. This multicentric retrospective study was carried out to determine clinical features, prognosis and relapse. PATIENTS AND METHODS: Patients with histologically proven, previously untreated follicular or marginal-zone PBL (MZL PBL) diagnosed from 1980 to 2003 were included in the study. Major end points were progression-free survival (PFS), overall survival (OS) and potential prognostic factors. RESULTS: We collected data on 60 cases of PBL [36 follicular and 24 marginal-zone lymphoma (MZL)]. Stage was I(E) or II(E) in 57 patients and IVE in three patients due to bilateral breast involvement. Surgery, chemotherapy and radiotherapy (RT), alone or in combination, were used as first-line treatments in 67%, 42% and 52% of patients, respectively. Overall response rate was 98%, with a 93% complete response rate. Five-year PFS were 56% for MZL and 49% for follicular PBL (P = 0.62). Relapses were mostly in distant sites (18 of 23 cases); no patients relapsed within RT fields. CONCLUSIONS: Our data showed an indolent behaviour of MZL PBL, comparable to other primary extranodal MZL. Conversely, patients with follicular PBL had inferior PFS and OS when compared with limited-stage nodal follicular non-Hodgkin's lymphomas, suggesting an adverse prognostic role of primary breast localisation in this histological subgroup.

Joint practice guidelines for radionuclide lymphoscintigraphy for sentinel node localization in oral/oropharyngeal squamous cell carcinoma.

Involvement of the cervical lymph nodes is the most important prognostic factor for patients with oral/oropharyngeal squamous cell carcinoma (OSCC), and the decision of whether to electively treat patients with clinically negative necks remains a controversial topic. Sentinel node biopsy (SNB) provides a minimally invasive method for determining the disease status of the cervical node basin, without the need for a formal neck dissection. This technique potentially improves the accuracy of histologic nodal staging and avoids overtreating three-quarters of this patient population, minimizing associated morbidity. The technique has been validated for patients with OSCC, and larger-scale studies are in progress to determine its exact role in the management of this patient population. This document is designed to outline the current best practice guidelines for the provision of SNB in patients with early-stage OSCC, and to provide a framework for the currently evolving recommendations for its use. Preparation of this guideline was carried out by a multidisciplinary surgical/nuclear medicine/pathology expert panel under the joint auspices of the European Association of Nuclear Medicine (EANM) Oncology Committee and the Sentinel European Node Trial (SENT) Committee.

Progressive multifocal leucoencephalopathy in the rheumatic diseases: assessing the risks of biological immunosuppressive therapies.

Progressive multifocal leucoencephalopathy (PML) is a rare and often fatal opportunistic infection that has been well reported in patients with rheumatic diseases. The contributions of predisposing factors such as underlying disease and immunosuppressive drug selection are incompletely understood but it would appear that patients with systemic lupus erythematosus may be at highest risk. Natalizumab, a biological agent approved for multiple sclerosis and Crohn's disease has the clearest pattern of small but definite risk. Although the risk due to rituximab is difficult to assess given the multiple confounders, continued vigilance is warranted. Rheumatologists need to become familiar with PML and feel able to help patients make shared and informed decisions about the risks when starting treatment with immunosuppressive therapies. In particular, rheumatologists need to be vigilant and pursue the diagnosis of PML in all patients with unexplained neurological signs or symptoms with clinical and MRI findings compatible with the diagnosis.

Tumour-like mass lesion: an under-recognised presentation of primary angiitis of the central nervous system.

OBJECTIVE: To describe the occurrence of mass lesions (ML) in primary angiitis of the central nervous system (PACNS) and assess the utility of diagnostic testing and treatment. METHODS: We examined the case records of the Cleveland Clinic (CC), Massachusetts General Hospital (MGH), and the English language medical literature, for biopsy-proven PACNS cases presenting as a solitary ML. Relevant clinical variables were extracted and analysed with JMP software. RESULTS: We identified a total of 38 ML: eight of 202 (4.0%) patients with CC/MGH and 30 of 535 (5.6%) patients with PACNS identified from the medical literature. A higher percentage (13 of 45; 29%) was seen in the amyloid-related angiitis subset. Poorer outcomes were reported in the amyloid group, with five deaths. Of the non-amyloid group, better outcomes were seen in the group treated with corticosteroids and cyclophosphamide as compared with the group treated with corticosteroids alone. CONCLUSIONS: Although rare, PACNS should be considered in the differential diagnosis of ML; greater awareness of this manifestation may facilitate more prompt diagnosis and treatment. Biopsy evidence of angiitis is required for diagnosis; specimens should routinely be stained for amyloid. While excision of the lesion may be curative, aggressive immunosuppressive therapy is associated with favourable outcomes and may obviate the need for surgery.

Locoregionally advanced nasopharyngeal carcinoma: induction chemotherapy with cisplatin and 5-fluorouracil followed by radiotherapy and concurrent cisplatin: a phase II study.

BACKGROUND: Chemoradiotherapy is the current standard of care for locoregionally advanced nasopharyngeal carcinoma. The purpose of this study was to assess the feasibility and efficacy of induction chemotherapy (CHT) followed by concomitant chemoradiotherapy in this patient population. PATIENTS AND METHODS: In this single-arm, phase II study, patients with locoregionally advanced nasopharyngeal carcinoma were treated with 3 cycles of induction CHT with cisplatin (100 mg/m(2) on day 1) and 5-fluorouracil (1,000 mg/m(2) continuous infusion on days 1-4) followed by 3 cycles of cisplatin (100 mg/m(2) on days 1, 22 and 43) and concurrent radiotherapy up to 70 Gy. The primary endpoint was objective response. RESULTS: Thirty-four patients were enrolled, and all completed both induction treatment and subsequent chemoradiotherapy. Objective response rates were 79.4% (95% CI 62.1-91.3) and 85.3% (95% CI 68.9-95.0) after induction CHT and chemoradiation, respectively. Treatment was well tolerated and toxicity was manageable. At a median follow-up of 29 months, 3-year overall survival and progression-free survival rates are 80.0% (95% CI 0.64-0.95) and 54.0% (95% CI 0.36-0.73), respectively. CONCLUSIONS: Induction CHT with cisplatin and 5-fluorouracil followed by concomitant chemoradiotherapy is a feasible and active regimen for patients with stage IIB-IVB nasopharyngeal carcinoma. This regimen resulted in excellent locoregional disease control and overall survival.

Arteriovenous malformation of the brain mimicking primary central nervous system vasculitis.

In the diagnosis of primary central nervous system (CNS) vasculitis, it is crucial to rule out clinical, angiographic, and pathological mimics. We report a case of arteriovenous malformation (AVM) mimicking primary CNS vasculitis. A young male presented with intracerebral haemorrhage and no other clinical, laboratory, or angiographic features suggesting vasculitis. Cerebral biopsy showed perivascular inflammation and slight infiltration of the muscular layer of cerebral vessels by chronic inflammatory cells close to the haemorrhagic areas. These findings led to a diagnosis of CNS vasculitis. The patient was initially treated with corticosteroids, but 10 months after the discovery and surgical repair of the AVM, the patient is not receiving any immunosuppressant and has not developed any features of cerebral or systemic vasculitis.

ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies: an infectious diseases perspective (Soluble immune effector molecules [II]: agents targeting interleukins, immunoglobulins and complement factors).

BACKGROUND: The present review is part of the ESCMID Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biological therapies. AIMS: To review, from an Infectious Diseases perspective, the safety profile of agents targeting interleukins, immunoglobulins and complement factors and to suggest preventive recommendations. SOURCES: Computer-based MEDLINE searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT: Patients receiving interleukin-1 (IL-1) -targeted (anakinra, canakinumab or rilonacept) or IL-5-targeted (mepolizumab) agents have a moderate risk of infection and no specific prevention strategies are recommended. The use of IL-6/IL-6 receptor-targeted agents (tocilizumab and siltuximab) is associated with a risk increase similar to that observed with anti-tumour necrosis factor-α agents. IL-12/23-targeted agents (ustekinumab) do not seem to pose a meaningful risk of infection, although screening for latent tuberculosis infection may be considered and antiviral prophylaxis should be given to hepatitis B surface antigen-positive patients. Therapy with IL-17-targeted agents (secukinumab, brodalumab and ixekizumab) may result in the development of mild-to-moderate mucocutaneous candidiasis. Pre-treatment screening for Strongyloides stercoralis and other geohelminths should be considered in patients who come from areas where these are endemic who are receiving IgE-targeted agents (omalizumab). C5-targeted agents (eculizumab) are associated with a markedly increased risk of infection due to encapsulated bacteria, particularly Neisseria spp. Meningococcal vaccination and chemoprophylaxis must be administered 2-4 weeks before initiating eculizumab. Patients with high-risk behaviours and their partners should also be screened for gonococcal infection. IMPLICATIONS: Preventive strategies are particularly encouraged to minimize the occurrence of neisserial infection associated with eculizumab.

Alteration of peripheral markers of copper homeostasis in Alzheimer's disease patients: implications in aetiology and therapy.

Alzheimer's disease represents a growing health problem because of the ongoing increase in life expectancy. Therefore understanding the molecular alterations responsible for neurodegeneration has become imperative in order to develop efficient strategies for the therapy. Mounting evidence suggests that the essential metal ion copper is intriguingly connected with the established molecular markers of Alzheimer's disease and that copper homeostasis is disturbed in affected individuals, leading to oxidative stress and neurodegeneration. This review summarizes the mechanisms of copper trafficking in cells and describes the relationship between copper, the amyloid precursor protein and beta-amyloid. Since one of the main goals of the research on Alzheimer's disease is the identification of blood markers to aid diagnosis and monitor the effects of therapeutic approaches, the results obtained in a series of studies on copper in the blood of Alzheimer's disease patients recently carried out in our laboratories are described.

Cytology and molecular mechanisms of drug-induced gingival hypertrophy: a rewiew.

INTRODUCTION: Gingival hypertrophy is a frequent condition associated to the increased number of patients taking some categories of drugs. The goal of this work is to emphasize the importance of diagnosis to set a proper therapy. MATERIAL AND METHODS: The plaque accumulation in patients having a poor oral hygiene damages the periodontium and requires the application of strict professional and home hygiene protocols. RESULTS AND CONCLUSION: The drug-induced gingival proliferation knowledge is essential in order to succeed in working with the internist and in planning a precise therapy, without interfering with the metabolism of drugs, often necessary and irreplaceable for patients' health.

Rheumatic immune-related adverse events of checkpoint therapy for cancer: case series of a new nosological entity.

Immunotherapy of cancer with checkpoint inhibitors has been associated with a spectrum of autoimmune and systemic inflammatory reactions known as immune-related adverse events (irAEs). Rheumatic irAEs are infrequently reported and extensively described. Here, we report our experience over an 18-month period with 15 patients evaluated in the rheumatology department for rheumatic irAEs. We identified 13 patients without pre-existing autoimmune disease (AID) who subsequently developed rheumatic irAEs, and two with established AID referred pre-emptively. irAEs encountered included: inflammatory arthritis, sicca syndrome, polymyalgia rheumatica-like symptoms and myositis. All cases required glucocorticoids, and three required a biological agent. Rheumatic irAEs led to temporary or permanent cessation of immunotherapy in all but five patients. One patient with pre-existing AID experienced a flare after starting immunotherapy. Our findings underscore that rheumatic irAEs are complex, at times require additional immunosuppressive therapy, and may influence ongoing immunotherapy regimens for the primary disease. Similar irAEs will be increasingly seen as checkpoint inhibitors adopted as standard of care in the community.
