Synergy of amoxycillin combined with clavulanate and YTR 830 in experimental infections in mice.

YTR 830, a new beta-lactamase inhibitor, is synergistic with amoxycillin in vitro against a number of beta-lactamase-producing organisms. The combination of amoxycillin-YTR 830 was compared to amoxycillin-clavulanate in the treatment of experimental Staphylococcus aureus, Citrobacter freundii and Proteus mirabilis infections in mice. Both combinations were synergistic with amoxycillin against all three test organisms. The amoxycillin-clavulanate combination was superior against S. aureus and C. freundii while amoxycillin-YTR 830 was more effective against P. mirabilis. The difference in efficacy between the two drug combinations appears to relate to the degree of protection afforded the animals by the beta-lactamase inhibitor alone. YTR 830 is a promising new agent and should undergo further investigation.

[Xanthogranulomatous pyelonephritis: presentation of an unusual case].

INTRODUCTION: Xanthogranulomatous pyelonephritis is a morphologically and clinically unique manifestation of chronic pyelonephritis with the formation of pus or granulomas. The most frequent predisposing factors for the development of xanthogranulomatous pyelonephritis are urinary obstruction (e. g., stones, tumors, congenital anomalies and functional impairment) and infection of the collecting system. CASE REPORT: We describe a 2-year-old female patient with unclear abdominal complaints, diarrhea, malaise, loss of appetite, weight loss, pale skin color, and recurrent and undulating fever in the presence of known left nephrolithiasis. Based on the clinical examination and imaging, above all, CT, the presumptive diagnosis of xanthogranulomatous pyelonephritis of the left kidney was made. A left lumbar nephrectomy was performed and histology confirmed the diagnosis. CONCLUSION: Xanthogranulomatous pyelonephritis is a relatively rare entity that is associated with obstruction (e. g., stones) and infection of the urinary tract. Its rarity and resultant unfamiliarity often delay diagnosis and therapy, which in turn affect the prognosis. Furthermore, this entity can be mistaken for renal tumors (renal cell carcinoma and Wilms tumor), but nowadays this should be mostly eliminated with the advances in the imaging methods.

Alteration of perirenal fat secondary to diffuse retroperitoneal infiltration.

Inflammatory effusions and diffuse neoplasia in the fatty retroperitoneal space, which can alter the perirenal fat, can be recognized radiographically because of density differences. The opacity of fluid and tumor accentuates the remaining fat which conforms to the renal contour. This perirenal fatty border appears as a lucent strip when the perirenal fat is not violated and as abnormal perirenal streakiness when the perirenal fat is infiltrated by fluid or tumor. Six cases are described.

[Primary bacterial aortitis].

Primary bacterial aortitis represents a rare disease with a high lethality. From June 1997 to April 1999 5 patients with an abdominal aortic infection were treated by resection of the infected aorta and in-situ reconstruction or by extra-anatomic bypass. There was no treatment in one case because of the infaust prognosis. 3 patients survived, one with a paraparesis as a result of spinal ischemia. On the basis of our patients the pathogenesis, clinical symptoms with diagnosis and the therapeutic options are discussed.

[Vena cava superior syndrome in total parenteral nutrition. Vena cava superior thrombosis caused by a central venous catheter].

Two patients developed superior vena cava syndrome following total parenteral nutrition through a central venous catheter. Infection may have contributed to the development of the superior vena cava thromboses. In one patient a "sleeve thrombus" probably caused multiple pulmonary embolisms after the catheter was withdrawn. The other patient had a mural thrombosis with complete occlusion of the superior vena cava. The author emphasizes the importance of early diagnosis and correct treatment in order to reduce the high mortality rate due to this serious complication to central venous catheters.
