Multipoint Schur algorithm and orthogonal rational functions: convergence properties, I
Classical Schur analysis is intimately connected to the theory of orthogonal
polynomials on the circle [Simon, 2005]. We investigate here the connection
between multipoint Schur analysis and orthogonal rational functions.
Specifically, we study the convergence of the Wall rational functions via the
development of a rational analogue to the Szeg\H o theory, in the case where
the interpolation points may accumulate on the unit circle. This leads us to
generalize results from [Khrushchev,2001], [Bultheel et al., 1999], and yields
asymptotics of a novel type.Comment: a preliminary version, 39 pages; some changes in the Introduction,

Renal involvement in the acquired immunodeficiency syndrome: Presentation, clinical course, and therapy
Acute renal failure developing during the clinical course of the acquired immunodeficiency syndrome (AIDS) has been related to complications of sepsis, nephrotoxic antibiotics, and recently to the development of glomerular lesions. Of 114 AIDS patients admitted to our hospital between January 1985 and June 1986, 11 patients (9.6%) developed acute renal failure. None of these 11 patients had a history of intravenous drug abuse or hypertension. All patients were male with an average age 35 years old, 81% were black, and all were bisexual or homosexual. Renal failure was attributed to AIDS-related focal glomerulosclerosis (five cases), prerenal azotemia (one case), acute interstitial nephritis (one case), and acute tubular necrosis (four cases). Approximately 15 weeks elapsed from the onset of renal failure to end-stage kidney disease. Only one of five patients survived more than six months after beginning dialysis. Acute renal failure is an important complication of AIDS with glomerular involvement detected in 45% of patients

Steroid-free immunosuppression after renal transplantation
Concerns about the side effects of chronic steroid therapy have prompted increasing interest in steroid-free immunosuppression for renal transplant recipients who are maintained on cyclosporine-based regimens. Studies to date suggest that at least 50% of cyclosporine-treated patients can be managed without steroid therapy. Reported benefits of avoiding or withdrawing steroid therapy have included improvements in hyperlipidemia, hypertension, and glucose intolerance and accelerated growth in children. Whether these effects will increase patient or allograft survival remains to be proved. Furthermore, the benefits of steroid-free immunosuppression must be weighed against the risk of precipitating allograft rejection. Although the elimination of steroids clearly increases the short-term risk of acute rejection, further studies are needed to determine the effects of steroid-free immunosuppression on long-term allograft function and to identify clinical or immunologic factors that can predict a successful outcome after the elimination of steroids
