Rhodococcus equi Sepsis in a Renal Transplant Recipient: A Case Study.

Rhodococcus equi is an unusual cause of infection in humans, but has emerged as an opportunistic pathogen among immunocompromised patients. Primary pulmonary involvement is the most common clinical presentation, although the spectrum of disease is broad. Diagnosing R.

Missense mutation and hexanucleotide duplication in the PAX2 gene in two unrelated families with renal-coloboma syndrome (MIM 120330).

We present a family with autosomal-dominant inheritance of renal insufficiency caused by renal hypoplasia in six individuals. In all affected individuals, signs of optic disk dysplasia were detected, but most patients were asymptomatic. A heterozygous missense mutation in the PAX2 gene causing a Gly75 to Ser substitution was present in all affected individuals.

Single dose pharmacokinetics of lamivudine in subjects with impaired renal function and the effect of haemodialysis.

Aims: The purpose of this study was to investigate the pharmacokinetics of a single oral dose of lamivudine administered to subjects with renal impairment and to determine whether lamivudine was dialysable in subjects with severe renal impairment undergoing haemodialysis.

Methods: Twenty-nine subjects were enrolled, nine with normal renal function (creatinine clearance (CL(CR)) 82-117 ml min(-1)), eight with moderately impaired renal function (CL(CR) 25-49 ml min(-1)), six with severe impairment (CL(CR) 13-19 ml min(-1)) and six with severe impairment who were also receiving haemodialysis. After an overnight fast, nondialysis subjects received a single oral dose of lamivudine.

High diagnostic performance of CT scan for analgesic nephropathy in patients with incipient to severe renal failure.

Recently, well performing diagnostic criteria for analgesic nephropathy in end-stage renal failure (ESRF) patients were defined by the demonstration of a bilateral decrease in renal volume combined with either bumpy contours or papillary calcifications. In this study, the diagnostic value of computed tomography (CT) scan was compared to the previously used renal imaging techniques (sonography and conventional tomography). In a first study, a cohort of 40 analgesic abusers (defined as daily use of analgesic mixtures during at least 5 years) and 40 controls, all ESRF patients without a clear renal diagnosis, were investigated with sonography, tomography and CT scan without injection of iodinated contrast material, to search for the imaging signs of analgesic nephropathy.
