[Prognostic value of fetal thymidine kinase measurements in breast cancer].

Estimation of fetal Thymidine Kinase activity in primary tumors could be a useful parameter in the assessment of early relapses in patients with breast cancer. In a group of 39 women followed up for 42 months, the percentage of early relapses and their frequency was significantly higher in patients whose tumors had a high level of enzyme activity than in others.

[Pyonephrosis complicated by a pyogenic psoas abscess. Apropos of a case].

Psoas abscess of pyogenic origin developed secondary to renal infection in a patient with coralliform lithiasis, a favorable outcome being obtained after nephrectomy and drainage of abscess. Clinical diagnosis is difficult but ultrasound and CT scan imaging provide useful data. Other causes of pyogenic abscess are discussed, the most frequent origin being digestive disease.
