PURPOSE/METHODS: Interface opacities were detected in a patient who underwent uncomplicated myopic keratomileusis. RESULTS AND DISCUSSION: Nocardia asteroides keratitis was confirmed by microbiologic work-up and guided the correct treatment. The eye recovered 20/60 spectacle-corrected visual acuity and had a residual stromal scar.
Clinic report case of a kidney-transplanted female who, after one year of normal functioning, developed xantogranulomatous pyelonephritis in the renal allograft. Clinical presentation was mesorenal tumoration causing pyelocaliecstasis, which coincided with a progressive decline of renal function due to interstitial rejection. Diagnosis by eco-doppler imaging, CAT, arteriography, renogram and descending pyelography were non-specific in relation to the process benignant or malignant nature. Surgical examination with obtention of biopsy was not conclusive with regard to diagnosis and so, during a second surgery, transplanctectomy was chosen. The histological examination showed that the expansive process of the allograft corresponded to a case of xantogranulomatous pyelonephritis. After reviewing the existing literature, only 4 cases were found reporting this rare condition in a renal allograft.
The authors analyze the randomized use of three ankle arthrodesis techniques. Indications for this procedure, which are pain, instability, deformity and articular degeneration, are common to the three groups. In group I the Gatellier-Adams technique was used by transfibular approach. In group II the Kenneth-Johnson technique was adopted, using Calandruccio external fixator. The same surgical procedure was adopted in group III, using crossed canulated screws as fixation device. The specific advantages and disadvantages of each method are discussed. The criteria for evaluation of the results are the final roentgenographic position of the foot and the achievement of union. The critical analysis conclude that the major indications for group I technique are cases of "in situ" arthrodesis, for group II infected cases and for group III cases with severe malalignment.
