RESUMO
Algerian hospitals have experienced a dramatic increase in methicillin-resistant Staphylococcus aureus (MRSA) prevalence in recent years. To investigate this phenomenon, we have determined molecular characteristics of 61 methicillin-resistant or -susceptible strains isolated between 2003 and 2007 in Oran Hospital. Susceptible isolates were related to diverse genetic backgrounds, of which clone with sequence type (ST) 8 accounted for most of the samples. Resistance to methicillin was almost limited to two international spreading clones; the most frequent, ST80, contained isolates producing Panton-Valentine leukocidine, with SCCmec type IV. The increase of MRSA prevalence observed in Western Algeria, in outpatients as well as in hospitalized patients, is linked to dissemination of ST80 strains usually considered as community-acquired MRSA.

Pylephlebitis or septic portal thrombophlebitis is a rare but serious condition which may occur following intra-abdominal sepsis from any source. Sigmoid diverticulitis is one of the most common sources. Modern imaging modalities, particularly CT, have increased the recognition of this condition. Standard treatment consists of anticoagulation plus antibiotic therapy to cover anaerobic and gram negative organisms. The duration of anticoagulation therapy remains controversial. Sigmoid colectomy may be required in cases of perforated diverticulitis or failure of medical therapy.

Urinary tuberculosis is frequent in Algeria. The discovery of the disease become difficult when one of the three criterium of the diagnostic does not allow a diagnosis of certitude. The authors reported the case of a 44 years-old patient admitted to hospital for tuberculous meningitis recovery from left nephrectomy for urinary lithiasis. The histology does not find specific lesions. Then, no antituberculous treatment is prescribed. The patient has developed renal and meningitis tuberculosis associated with urinary lithiasis. Koch's bacillus is found in the urine. The evolution under medical treatment was excellent. The urinary lithiasis has hided tuberculosis and the discovery of the disease was late.
