[Plasmacytosis and dengue fever: an underestimated abnormality?].

Introduction: A significant peripheral blood plasmacytosis is a rare finding associated with viral infections. We reported five consecutive cases of dengue virus infection, with circulating plasma cells.

Case Reports: Three women and two men, aged 26 to 75 years, had returned from French West Indies less than one week before the onset of the symptoms (mean: 2.

[Retroperitoneal pseudotumor related to native brucellosis in France].

Despite their rarity, some causes of retroperitoneal granulomatous tumor must be kept in mind. We report a 41-year-old man who presented with a right psoas mass. No spondylitis was associated.

[Non-tuberculous systemic granulomatosis mimicking sarcoidosis but related to a specific etiology. Study of 67 cases].

Purpose: Systemic granulomatosis (SG) are frequently encountered in internal medicine. Despite a large list of aetiologies, the investigations remain often negative leading to the diagnosis of atypical sarcoidosis. The spectrum of the causes, as well as evolution of these SG is not clearly delineated in the literature.

[Tuberculoma and tuberculous meningeal-radiculitis with paradoxical progression during treatment].

Introduction: Neuromeningeal tuberculosis of deleterious, paradoxical, progression despite appropriate antibiotic therapy is rare.

Observation: An immunocompetent woman exhibited an immediately disseminated form of tuberculosis with progressive neurological involvement associating expanding intracranial tuberculomas and meningeal-radiculitis despite adapted anti-tuberculosis quadritherapy.

Discussion: During anti-tuberculosis therapy clinical worsening is rare, particularly when 2 different manifestations are associated and the worsening occurs in an immunocompetent patient.

[Acute aseptic meningitis in adults. Retrospective study of 32 cases].

Objective: The objective of this study was to analyze the characteristics of a series of acute aseptic meningitis (AAM) (defined by sterile cerebrospinal fluid (CSF) with more than 10 leucocytes per mm3 and a neutrophilic polynuclear-rich formula). We analysed the initial management, the reasons for antibiotic and/or antiviral treatment, the aetiologies, the need for lumbar puncture and the progression..

[Paraneoplasic pandysautonomia with anti-Hu antibodies: a presentation of pulmonary adenocarcinoma identified by PET scanning].

A 74-year-old man developed pandysautonomia with severe orthostatic hypotension. Search for a paraneoplastic etiology was confirmed with the positivity of anti-Hu antibodies. [18] Fluorodeoxyglucose positron emission tomography (PET) enabled recognition of a lung adenocarcinoma.

[Intestinal pneumatosis. Right colon cystic form with linear aspect on scan].

Introduction: Digestive pneumatosis corresponds to the presence of air in a wall of digestive tract. It is common to oppose primary cystic-type pneumatosis, involving the left colon, with linear-type pneumatosis that may affect the whole of the digestive tract.

Observation: In a 41 year-old man presenting with Sharp's syndrome, abdominal pain occurred revealing an isolated right colon pneumatosis.

[Acute renal failure during severe malaria: physiopathology and therapeutic management. Apropos of 2 cases].

Renal failure secondary to acute tubular necrosis is a common complication of severe Plasmodium falciparum malaria. The purpose of this report is to describe two cases of severe malaria featuring acute renal failure observed in young patients who had failed to comply with chemoprophylaxis. Occurrence of renal failure was delayed four to seven days in relation to the beginning of the malaria attack.
