[Psoas abscesses reviewed].

Psoas abscesses are rare. In the absence of specific symptoms and signs, their diagnosis was usually difficult. Medical imaging advances have helped in their diagnosis and treatment.

Multicenter pilot survey of resistant bacteria in the Mediterranean area.

With the aim of testing the feasibility of a multiresistant bacteria (MRB) surveillance methodology and evaluating the level of antimicrobial resistance and dissemination of resistant pathogens in the Mediterranean area, a pilot study was carried out in nine university hospitals in Algeria, Tunisia and France. The results indicate that third-generation cephalosporin-resistant Enterobacteriaceae comprise the major MRB in Algerian and Tunisian hospitals. In France, the highest incidence rates were found for methicillin-resistant Staphylococcus aureus, while in Tunisian hospitals, imipenem-resistant Acinetobacter baumannii seems to be a particularly prevalent organism.

Clinical and laboratory features of murine typhus in central Tunisia: a report of seven cases.

Introduction: Murine or endemic typhus, caused by Rickettsia typhi, has been reported in all continents. In the 1970s, no cases of murine typhus were diagnosed in Tunisia.

Methods: The clinico-epidemiological characteristics of seven cases of murine typhus diagnosed at our hospitals since 1993 are reported.

[Pyogenic splenic abscesses. A review of 8 cases].

Purpose: Pyogenic splenic abscess is un uncommon and potentially life-threatening disease. Due to inconspicuous and nonspecific clinical picture, it remains a diagnostic challenge. Medical imaging progresses are helpful for diagnosis and treatment.

[Infectious urgencies in an emergency medical service].

The aim of this study is to evaluate the frequency of infectious urgencies and the quality of their management in an emergency medical service. During the period of study, 21737 consultants are recorded, from which 2011 for an infectious urgency (9,25%), pharyngitis with rhinitis excluded. 692 patients are hospitalized and 1074 receive ambulatory antibiotics.

Posterior segment manifestations of Rickettsia conorii infection.

Purpose: To characterize and analyze the posterior segment manifestations of Mediterranean spotted fever (MSF), an infectious disease caused by Rickettsia conorii.

Design: Prospective, noncomparative case series.

Participants: Thirty patients (60 eyes) with serologically proven MSF at the acute stage.

[Sweet's syndrome].

Sweet's syndrome or acute febrile neutrophilic dermatosis is relatively frequent. It can be isolated or associated to other diseases, particularly, inflammatory or autoimmune diseases, lymphoproliferative or malignant disorders. In this retrospective study, we report 10 cases of Sweet's syndrome recorded over a 42 months period.

[Lyme disease in Tunisia, results of a clinical and serological study (1992-1996)].

Lyme disease was suspected in 271 patients seeking hospital care between 1992 and 1996. The sera of all these patients were tested by ELISA for antibodies against Borrelia burgdorferi. Twenty-nine cases of Lyme disease were identified, each involving neurological and articular problems.

[Septicemia caused by A, B, C and G groups of beta-hemolytic streptococci].

During a five and a half years' period, 805 strains of beta-haemolytic groups A, B, C and G streptococci were isolated. Among these, 28 were responsible for bacteremia; 57 percent group B and 32 percent group A. All strains were susceptible to beta-lactam antibiotics; 4 strains were resistant to macrolides.
