Post-transplant Lymphoproliferative Disorder--a case of late-onset T-cell lymphoma after failed renal transplant.

Post-transplant lymphoproliferative disease (PTLD) is a rare but life-threatening complication after solid organ transplantation. The risk of PTLD varies with recipient age, serostatus of the donor and the recipient for Epstein-Barr virus, type of organ transplanted, and intensity of immunosuppression. The risk of PTLD is highest in the early post-transplant period, but the cumulative risk increases with time. We report a case of PTLD occurring 17 years after renal transplantation in a 59-year-old woman.

Reliability of AOFAS diabetic foot questionnaire in Charcot arthropathy: stability, internal consistency, and measurable difference.

BACKGROUND: The development of Charcot changes is known to be associated with a high rate of recurrent ulceration and amputation. Unfortunately, the effect of Charcot arthropathy on quality of life in diabetic patients has not been systematically studied because of a lack of a disease-specific instrument. The purpose of this study was to develop and test an instrument to evaluate the health-related quality of life of diabetic foot disease. METHODS: Subjects diagnosed with Charcot arthropathy completed a patient self-administered questionnaire, and clinicians completed an accompanying observational survey. The patient self-administered questionnaire was organized into five general sections: demographics, general health, diabetes-related symptoms, comorbidities, and satisfaction. The scales measured the effect in six health domains: 1) general health, 2) care, 3) worry, 4) sleep, 5) emotion, and 6) physicality. The psychometric properties of the scales were evaluated and the summary scores for the Short-Form Health Survey (SF-36) were compared to published norms for other major medical illnesses. RESULTS: Of the 89 enrolled patients, 57 who completed the questionnaire on enrollment returned a second completed form at 3-month followup. Over the 3-month followup period most of the patients showed an improvement in the Eichenholtz staging. The internal consistency of most was moderate to high and, in general, the scale scores were stable over 3 months. However, several of the scales suffered from low-ceiling or high-floor effects. Patients with Charcot arthropathy had a much lower physical component score on enrollment than the reported norms for other disease conditions, including diabetes. CONCLUSIONS: Quality of life represents an important set of outcomes when evaluating the effectiveness of treatment for patients with Charcot arthropathy. This study represents an initial attempt to develop a standardized survey for use with this patient population. Further studies need to be done with larger groups of patients to refine the tool and to begin the validation process. The instrument developed could be used for comparing treatment strategies for Charcot arthropathy.

Isolated pleural effusion as a presentation of high cardiac output heart failure in a hemodialysis patient.

Congestive heart failure is a well-recognized complication of hemodialysis arteriovenous fistula. Symptoms of dyspnea are usually associated with signs of congestive heart failure including pulmonary edema, pleural effusions, lower extremity edema, and liver enlargement, to name a few. We present a case of a gentleman with end-stage renal disease on chronic hemodialysis, which developed acute bilateral transudative pleural effusions in the absence of other signs of systemic venous congestion, associated with pulmonary venous congestion. We also discuss the pathogenesis and role of hemodialysis in management of this patient.

Decompensated high-output congestive heart failure in a patient with AVF and the role of right heart catheterization: a case study.

A 70-year-old Caucasian male presented 8 months postcadaveric renal transplant with slowly progressive shortness of breath, abdominal distention, and cough for a duration of a few days. Thorough evaluation found him to have severe pulmonary hypertension (PH) on echocardiogram with decompensated high-output congestive heart failure. A right heart catheterization was done, which confirmed elevated right-sided pressures and high cardiac output. The mean pulmonary artery pressure, on a Swan-Ganz catheter, improved from 37 to 30 mmHg on partial manual occlusion of his still functioning hemodialysis arteriovenous fistula. Subsequently, the patient underwent ligation of the fistula and this led to gradual improvement in his symptoms. Follow-up right heart catheterization and echocardiogram showed marked improvement and normalization of right heart pressures. We recommend that patients with arteriovenous fistula should undergo close monitoring for development of early signs and symptoms of congestive heart failure and screening for PH by echocardiography post-kidney transplant. Right heart catheterization should be considered if screening is positive. Risk and benefit of fistula closure should be weighed in face of reduced survival from PH in dialysis patients and closure should be considered in post-transplant patients.

Pulmonary Arteriovenous Malformation (AVM) Causing Tension Hemothorax in a Pregnant Woman Requiring Emergent Cesarean Delivery.

Pulmonary arteriovenous malformations (PAVMs), although most commonly congenital, are usually detected later in life. We present a case of a 25-year-old woman with no previous history of AVM or telangiectasia, who presented with life-threatening hypoxia, hypotension, and pleuritic chest pain in 36th week of gestation. Chest tube placement revealed 4 liters of blood. Patient was subsequently found to have bleeding pulmonary AVM as the source of hemothorax. Successful embolisation of the bleeding vessel followed by thoracoscopic evacuation of the organized clot relieved the hypoxia. Further screening for AVM revealed large splenic AVM for which patient underwent splenectomy in the coming months.

Impact of hospital and surgeon volume on in-hospital mortality from radical cystectomy: data from the health care utilization project.

PURPOSE: We determined the influence of hospital and surgeon volume on various outcome parameters after radical cystectomy for bladder cancer. MATERIALS AND METHODS: All inpatient discharges after radical cystectomy for bladder cancer (1988 to 1999) from the Health Care Utilization Project-Nationwide Inpatient Sample were included in the analysis. Hospital and individual surgeon volume of discharges per year were separated into terciles. Outcome measures were in-hospital mortality, length of stay (LOS), and inflation adjusted charge per admission. Mortality was compared among hospital volume levels using the Mantel-Haenszel chi-square test while the LOS and charges were compared using ANOVA. Multivariate linear and logistic regression analyses were used to adjust for confounding factors. All the analyses were also performed in 3 different age strata (younger than 50 years, 50 to 69 years and 70 years or more). RESULTS: There were 13,964 patients who underwent radical cystectomy. Overall in-hospital mortality was 408 of 13,964 (2.9%), average LOS was 14 days (+/- SD 10.28) and average charges were 47,146 dollars (+/- SD 45,263 dollars). In-hospital mortality was significantly associated with higher volume particularly for patients older than 50 years. Surgeon volume did not influence in-hospital mortality except for patients in the 50 to 69-year-old age group. Results of multivariate regression analysis demonstrated hospital volume was a significant predictor of in-hospital mortality but this effect was lost when controlling for surgeon volume. LOS was significantly higher for low volume surgeons. High volume hospitals had lower average total charges compared with the low and moderate volume hospitals. CONCLUSIONS: Hospital and surgeon volume have a significant impact on in-hospital mortality and LOS after radical cystectomy. Radical cystectomy performed at a higher volume center may result in lower charges and shorter hospital stay while decreasing the likelihood of in-hospital mortality.

Impact of malpractice caps on use and outcomes of radical cystectomy for bladder cancer: data from the surveillance, epidemiology, and end results program.

PURPOSE: The impact of malpractice awards on insurance premiums and health care delivery generates much concern. To our knowledge no data exist regarding the impact of caps, or upper limits, on awards for noneconomic damages (also termed pain and suffering) on health care delivery patterns or outcomes. We investigated the effect of caps on the use of and outcomes following aggressive surgical treatment (radical cystectomy) in patients with bladder cancer. MATERIALS AND METHODS: We performed a retrospective cohort study of patients with bladder cancer who underwent radical cystectomy, identified from the Surveillance, Epidemiology, and End Results (SEER) Program database. Cystectomy rates and post-cystectomy disease specific survival were compared between SEER regions with and without a cap, while controlling for other variables. RESULTS: A significantly greater proportion of patients with stages III and IV bladder cancer underwent cystectomy in SEER regions with a cap. Cap status was a significant predictor of survival from bladder cancer. CONCLUSIONS: Radical cystectomy for bladder cancer is performed more often even for advanced bladder cancer in geographic regions with a cap with a positive impact on survival. The institution of caps may have beneficial effects on patterns of health care beyond that of merely decreasing insurance premium costs.

Association between volume and charges for most frequently performed ambulatory and nonambulatory surgery for bladder cancer. Is more cheaper?

PURPOSE: We investigated the relationship between provider volume and charges for transurethral bladder tumor resection (TURBT) and radical cystectomy in patients with bladder cancer. MATERIALS AND METHODS: The National Inpatient Sample (1988 to 1999) of the Health Care Utilization Project, and State Ambulatory Surgery Databases for Wisconsin and Florida (2000 data set) were used for analysis. All patients with bladder cancer who had undergone radical cystectomy or TURBT as the principal procedure were identified. Hospitals and surgeons were categorized into terciles of volume based on the average number performed per year. The average hospital charge per discharge/procedure corrected to 2000 levels was calculated. One-way ANOVA with the Bonferroni correction was used to compare charges between different volume levels. RESULTS: A total of 13,498 patients who underwent radical cystectomy and 5,954 who underwent TURBT were included in the analysis. Charges for radical cystectomy were 5,648 USD lower at high volume hospitals than at low volume hospitals (p <0.001). High volume surgeons were 2,976 USD less expensive than low volume surgeons (p =0.054). For TURBT total hospital charges at high volume hospitals were 1,013 USD more than at low volume hospitals (p <0.0001), while average total hospital charges for procedures performed by high volume surgeons were 919 USD less compared to low volume surgeons (p <0.0001). CONCLUSIONS: High risk inpatient procedures for bladder cancer such as cystectomy, which are more influenced by systems of care, are less expensive to perform at high volume centers. Lower risk ambulatory procedures for bladder cancer, such as TURBT, which are not influenced by systems of care, may be more cost efficiently performed by high volume surgeons at low volume centers.
