[Olmesartan therapy and enteropathy: About two cases and review of the literature].

Introduction: Olmesartan is an angiotensin II receptor blocker, used to treat arterial hypertension. Severe digestive manifestations have been associated with olmesartan, including sprue-like enteropathy and lymphocytic colitis.

Observations: We report two cases of sprue-like enteropathy associated with olmesartan, leading to malabsorption syndrome related to villous atrophy.

Minimising the risk of Mycobacterium chimaera infection during cardiopulmonary bypass by the removal of heater-cooler units from the operating room.

Introduction: Mycobacterium chimaera ( M. chimaera) is a recently characterised bacterium that can cause life-threatening infections in small numbers of patients who undergo cardiopulmonary bypass during cardiac surgery. The likely mode of transmission is thought to occur through aerosolisation from contaminated water reservoirs.

[Facial diplegia as the presenting feature of Lyme disease].

Introduction: Diagnosis of neuroborreliosis may be difficult. Neuroborreliosis mainly results in lymphocytic meningitis and in meningoradiculitis (67-83% of cases).

Case Report: We report the case of a patient who developed a sudden facial diplegia, revealing neuroborreliosis proved by positive blood and cerebrospinal fluid serology.

[Acute reactive arthritis after intravesical instillation of bacillus Calmette-Guérin. Two case reports and literature review].

Introduction: Intravesical bacillus Calmette-Guérin (BCG) therapy-associated articular complications are uncommon, occurring in only 0.5 to 1% of the patients.

Observations: We report two patients who were given intravesical BCG therapy for superficial bladder cancer.

[Muscle lymphoma: a case report].

Skeletal muscle involvement is uncommon in lymphoma, occurring in less than 1.5% of patients. We report the original case of a 61-year-old man who presented with pseudotumoral muscle lesions of the lower limbs, revealing non-Hodgkin T-cell lymphoma.

Ascites as the first manifestation of polyarteritis nodosa.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that affects numerous organs, particularly the digestive tract (33-52% of cases). However, isolated ascites has rarely been described in patients with PAN. We observed a patient who had developed ascites revealing PAN, and because of suspected malignancy laparotomy and abdominal surgery were performed, including systematic total abdominal hysterectomy, bilateral salpingo-oophrectomy, submesocolic omontectomy and appendicectomy.

[Spontaneous splenic hematoma: trauma injury or drug reaction or both?].

Introduction: Spontaneous splenic hematomas are uncommon and frequently associated with infectious, hematologic, or neoplastic diseases. Presentation is typically acute but progressive forms have been described.

Case: We report the case of a 45-year-old man consulting for abdominal pain that was found to be due to a spontaneous splenic hematoma.

Intravascular large B-Cell lymphoma with bone marrow involvement and superior sagittal sinus thrombosis: report of a case successfully treated with a CHOP/rituximab combination regimen.

Intravascular large B-cell lymphoma (ILBCL) is a rare subtype of diffuse large B-cell lymphoma (as currently recognized by the World Health Organization classification) and is characterized by proliferation of mature B-cells within the lumina of small and medium vessels. We report on a 66-year-old man who presented with a fever of undetermined origin, a splenomegaly, and an elevated lactate dehydrogenase level. The diagnosis of ILBCL was established by a bone marrow biopsy that showed CD20+ tumor cells confined within the lumina of sinuses.

[Tuberculosis peritonitis: an always present disease. About 4 new cases].

Introduction: Tuberculous peritonitis, a major problem in developing country, occurs preferentially in immigrant population and in patients with acquired immune deficiency syndrome (AIDS). Although rare in France, it did not disappear and epidemiological, clinical and therapeutic approach deserve to be reminded.

Exegesis: We reported 4 patients (immigrants in two cases), occurred in caucasian and African persons (one with AIDS).

Multiple cerebral abscesses as a complication of Mycobacterium fortuitum infection.

Mycobacterium fortuitum is a rapidly growing, nontuberculous mycobacteria that has rarely been associated with central nervous system impairment. We describe the case of a patient who developed multiple cerebral abscesses revealing Mycobacterium fortuitum infection. Brain biopsy specimens showed suppurative, noncaseating, granulomatous inflammation consisting of epithelioid histiocytes and multinucleated giant cells.

[Cutaneous aseptic abscesses, manifestations of neutrophilic diseases].

Background: Neutrophilic skin disease includes several entities: Sweet syndrome, pyoderma gangrenosum, erythema elevatum diutium, Sneddon-Wilkinson sub-keratous pustulosis, and neutrophilic eccrine hidradenitis. We report two cases of aseptic abscesses which correspond to the deepest anatomoclinical form of neutrophilic dermatosis.

Case Reports: A 28-year-old man was hospitalized for fever and abdominal pain with bloody diarrhea in relation with Crohn's disease.

[Does hepatitis c virus-related autoimmune thyroiditis exist? Reflections on a controlled study of 58 consecutive subjects].

Purpose: Interferon alpha treatment for virus C hepatitis may be responsible for autoimmune thyroiditis. Relationships between thyroiditis and virus C infection are still debated. The aim of this study was to evaluate the existence of this association.
