Abstract: Introduction: Disseminated non-tuberculosis mycobacterial infections are associated with a defect of the cellular immune response. They have been mainly reported in AIDS patients. Cases related to the presence of anti-interferon-γ autoantibodies are rare. Case report: We report a non HIV-infected 45-year-old Thai woman, with a past medical history of Graves’ disease. She presented with recurrent disseminated and severe non-tuberculous mycobacterial infections that were related to the production of anti-interferon-γ autoantibody. The diagnosis was suspected in the presence of a negative interferon-γ release assay (IGRA) including with the positive control, and evidenced by the identification of specific antibodies. Conclusion: Anti-interferon-γ autoantibody production is a rare cause of non tuberculous mycobacterial infection. Such a mechanism should be suspected in non HIV-infected patients and especially in those having an Asiatic ethnicity or an associated immune disorder. A negative IGRA (including with the positive control) is a reliable diagnostic tool and should be completed with the identification of specific autoantibodies. [Copyright &y& Elsevier]

Abstract: Purpose: Psoas abscess is a rare disease in developed countries. Its diagnosis is difficult and any delay could lead to a worsen prognosis. The aim of this study is to determine the best diagnostic and therapeutic practices. Methods: A retrospective study of psoas abscess that occurred during six months was performed. Results: Six cases of secondary psoas abscess are reported. They were associated with spondylodiscitis in three cases, arthritis and gynaecologic infection in the three remaining cases. Anatomic diagnosis was performed by tomodensitometry. Microbiologic diagnosis was obtained by blood culture or direct puncture of the abscess. Antibiotics were associated with percutaneous drainage in two cases, with simple puncture in one case, and with surgery in one case. A local improvement w observed in all cases. The oldest patients presented the worst complications which were not directly caused by the abscess. Conclusion: ● Physicians must be aware of psoas abscess because of their increasing incidence. ● Despite the fact that digestive pathologies are the main cause of secondary psoas abscess, bone infections, particularly spine infections, should be taken into consideration. ● Tomodensitometry guided puncture or percutaneous drainage are of diagnostic and therapeutic interest. ● Infectious samples must be taken before starting antibiotics, which have to be efficient against Gram negative bacillus, anaerobes and Staphylococcus aureus. ● Surgery must be quickly performed when the primary infection localisation need it, in case of voluminous abscess or when antibiotics and drainage are inefficient.

- Abstract
Introduction: Periarteritis nodosa can be associated with streptococcal infections in children. We report two cases of adult cutaneous periarteritis nodosa that disappeared after the treatment of dental infection., Exegesis: A 23-year-old woman presented with necrotic ulceration on the legs for 6 months, with a histology of necrotizing vasculitis. Many sites of dental infections could be noted. Immunological data were negative and so were serologies of hepatitis. Corticosteroid therapy failed. The teeth removal with antibiotic therapy allowed the disappearance of cutaneous lesions in a month. A 26-year-old woman was hospitalized for growing thin, fever, diffuse arthralgia and myalgia and cutaneous nodules on the legs with necrotizing vasculitis on dermal vessels at histological analysis. The biology showed no pecularity. Radiography of the teeth showed many dental infection sites. The removal of six teeth with antibiotic therapy led to the disappearance of vasculitis in 6 weeks., Conclusion: The search for an infectious problem is important when vasculitis is diagnosed, in particular periarteritis nodosa. The treatment of dental infection could occasionally mean avoiding immunosuppressive therapy in certain cases.
