The clinical stage of groin lymph nodes and pathological findings of penectomy specimens allowed us to generate a nomogram to predict the probability of metastatic lymph node involvement in patients with squamous cell carcinoma of the penis. The statistical model showed an excellent ability to identify the patients with lymph node metastases and good calibration.

In this article we propose 2 models to predict the 5-year cancer specific survival probabilities of patients with squamous cell carcinoma of the penis. Both models showed good discriminating power and calibration in predicting patient 5-year cancer specific survival. These nomograms could improve the quality of prognostic data provided to patients and support physicians in planning treatment.

Objective Rheumatology is among the least compensated specialties in medicine today. This is a significant problem for clinical rheumatologists in academic medicine who are often expected to earn their salaries through clinical practice alone. Additionally, academic rheumatologists usually cannot generate revenue through office laboratory monitoring, radiographs, or bone densitometry to supplement their income (i.e., downstream income). The purpose of our study was to examine revenue generated from downstream income to a university by a clinical‐academic rheumatologist. Methods Consecutive outpatients (n = 127) seen predominately by one academic rheumatologist over one month of clinic were followed for 18 months. The total physician compensation for patient visits was calculated and compared with the revenue generated from laboratory tests, radiologic studies, consultations, and specific rheumatologic treatments and procedures performed or ordered. Medicare reimbursement rates for 2003 were used as compensation standards for all charges. Results Physician office visit billing generated $36,297 from 730 office visits. The total amount of downstream income from these office visits was $363,813 ($47,386 from laboratory tests, $35,582 from radiologic studies, $8,159 from rheumatologic procedures, $261,584 from rheumatologic infusions, and $11,101 from initial consultations). Therefore, $10.02 of downstream revenue was generated for every $1.00 of office visit compensation applied to the academic rheumatologist's salary. Conclusion Although academic rheumatologists struggle to bill their salaries through seeing more patients, they are clearly a bargain for a university hospital because they generate >$10.00 for every $1.00 they receive for an office visit.

The natural history of post-extracorporeal shock wave lithotripsy residual stone fragments (clearance, growth and aggregation) is incompletely known, even though they are believed to constitute a risk in terms of new stone formation and persistent infection of the urinary tract. We addressed this issue and the hypothesis that alkaline citrate therapy improves residual stone fragment clearance in a 12-month followup study. There were 40 sterile calcium and 30 struvite stone patients with residual fragments after extracorporeal shock wave lithotripsy (diameter less than 5 mm.) consecutively enrolled and randomly assigned to a citrate therapy (6 to 8 gm. per day) or control (hygienic measures only) group. Infection stone patients also received adequate antibiotic therapy throughout the study. Among the patients in the untreated sterile group 21% and 32% were stone-free at 6 and 12 months, respectively. In the infection group these figures were 27% and 40%, respectively. Among the untreated sterile calcium stone patients in whom clearance was not achieved a high percentage experienced residual fragment growth or reaggregation. Citrate therapy significantly improved the stone clearance rate in the sterile (at 6 and 12 months 65% and 74% were stone-free, respectively) and infection (71% and 86%, respectively) stone patients, and prevented residual fragment growth or reaggregation in subjects in whom clearance was not achieved. The data show that growth and persistence are common in the natural history of residual stone fragments. Citrate ameliorated the outcome of these residual fragments by reducing the growth or agglomeration, and by increasing the clearance rate in calcium oxalate and in infection stone patients.

These guidelines are intended to assist physicians and patients in the decision-making process regarding the management of LUTS/BPH, and support the process of continuous improvement of the quality of care and services to patients.
