Compared Burden of Psoriasis, Atopic Dermatitis, Hidradenitis Suppurativa, and Chronic Urticaria: Baseline Characteristics of the Patients Included in the OMCCI Cohort - A French, Prospective Multicenter Study of Chronic Inflammatory Dermatoses.

Introduction: Chronic inflammatory dermatoses (CIDs) can significantly affect patients' lives. The Observatory of Chronic Inflammatory Skin Diseases (OMCCI) cohort was initiated to quantify the impact and disease evolution of four CID over 4 years' follow-up; at least 1,000 patients per CID are planned to be enrolled. The objective of this study was to present baseline characteristics of patients included in the OMCCI cohort between December 2020 and September 2022.

[Vancomycin-induced DRESS syndrome: a case report].

DRESS syndrome is a severe adverse drug-induced reaction, characterized by generalized skin rash associated with hypereosinophilia, lymphocytosis and internal organ involvement. Antiepileptics, sulfamides and allopurinol are the most frequently reported drugs; vancomycin is less common. We report a case of vancomycin-induced DRESS syndrome in a 69-year-old male patient.

[Primary effusion lymphoma in two kidney transplant recipients].

Background: Primary effusion lymphoma (PEL) is a highly malignant non-Hodgkin lymphoma associated with Kaposi's sarcoma-associated herpesvirus/human herpesvirus-8 infection (KSHV/HHV-8). It is chiefly seen in HIV patients and is rare in transplant recipients, possibly going unrecognized.

Observation: We describe two male kidney transplant recipients, aged 47 and 51 years, followed for Kaposi's sarcoma in skin, lymph nodes, gastrointestinal (GI) tract and lung whose disease was poorly controlled by sirolimus and chemotherapy.
