A case of purulent pneumococcal pericarditis

Background

Purulent bacterial pericarditis is a rare and potentially fatal disease. The course may be fulminant, and the presentation may pose a diagnostic challenge.

Are Medicare's Nursing Home Compare Ratings Accurate Predictors of 90-Day Complications,Readmission, and Bundle Cost for Patients Undergoing Primary Total Joint Arthroplasty?

Background

Nursing Home Compare (NHC) ratings, created and maintained by Medicare, are used by both hospitals and consumers to aid in the skilled nursing facility (SNF) selection process. To date, no studies have linked NHC ratings to actual episode-based outcomes. The purpose of this study was to evaluate whether NHC ratings are valid predictors of 90-day complications, readmission, and bundle costs for patients discharged to an SNF after primary total joint arthroplasty (TJA).

Long-term followup of subclinical human papillomavirus infection treated with the carbon dioxide laser and intraurethral 5-fluorouracil: a treatment protocol

We evaluated 162 high risk male patients for the presence of subclinical anogenital human papillomavirus infection with magnified penile surface scanning. Infected patients were treated as outpatients with the carbon dioxide laser under local anesthesia. Of the patients 43 were followed for a mean of 8.7 months or 2.1 treatments after the initial treatment (range 3 to 30 months). A subset of 10 patients was followed for more than 20 months or 6.2 treatments. To date a 51% recurrence rate has been observed in the over-all population and a 50% recurrence rate was noted in the 20-month followup population. In a separate arm of this study a small number of patients (15) with deoxyribonucleic acid typed subclinical intraurethral disease plus subclinical skin lesions were treated with topical carbon dioxide laser therapy for the penile lesions and adjuvant intraurethral 5% 5-fluorouracil. Mean followup in the group was approximately 4 months. The addition of intraurethral therapy in this positive human papillomavirus reservoir group had no significant effect on the high rate of human papillomavirus recurrence.     

A pharmacokinetic comparison of the corn oil versus microemulsion gelcap formulation of cyclosporin used de novo after renal transplantation

The initial poor absorption of the corn oil-based, gel capsule oral formulation of cyclosporin (CyA) greatly limits its use for inception of immunosuppressive therapy. Insufficient drug concentrations during the early post-transplant period predispose to renal allograft rejection. The present study served to compare the time required to achieve therapeutic CyA concentrations after de novo administration of the corn oil-based gel capsule (CyA-GC; n = 11) versus the microemulsion (CyA-ME; n = 11) formulation of CyA. During the 1st month after renal transplantation, patients underwent serial pharmacokinetic profiling from which we obtained observed and dose-corrected values of several parameters. Although patients in neither the CyA-GC nor the CyA-ME group adequately absorbed the drug during days 0–2, from day 3 to 4 patients in the CyA-ME group showed significantly greater absorption than those in the CyA-GC group (P = 0.041). Patients in the CyA-ME group reached the 1st month target average concentration (C_av) values ( ≥ 550 ng/ml) earlier than those in the CyA-GC group and required significantly lower daily CyA doses (P = 0.018). We conclude that therapeutic CyA levels can be achieved more rapidly and with lower doses of the drug after de novo administration of CyA-ME than with CyA-GC.
