Incidence, Timing, and Pattern of Atypical Recurrence after Minimally Invasive Surgery for Urothelial Carcinoma.

The management of urothelial carcinoma has evolved with the introduction of minimally invasive techniques such as laparoscopic or robotic procedures, challenging the traditional approach of open surgery, and giving rise to atypical recurrences (ARs). ARs include port-site metastasis and peritoneal carcinomatosis, yet discrepancies persist among authors regarding their precise classification. Incidence rates of ARs vary widely across studies, ranging from less than 1% to over 10% in both muscle-invasive bladder cancer (MIBC) and upper tract urothelial tumor (UTUC). Peritoneal metastases predominate as the most common ARs in patients with MIBC, while retroperitoneal metastases are prevalent in those with UTUC due to differing surgical approaches. The timing of AR presentation and survival outcomes closely mirror those of conventional recurrences, with which they are frequently associated. Pneumoperitoneum has progressively been regarded less as the cause of ARs, while surgical-related risk factors have gained prominence. Current major surgical-related causes include tumor spillage and urinary tract violation during surgery, avoidance of endo bag use for specimen extraction, and low surgical experience. Factors such as tumor stage, histological variants, and lympho-vascular invasion correlate with the risk of ARs, suggesting a close association with tumor biology. Further studies are required to better understand the incidence, risk factors, characteristics, and outcomes of ARs.

Trends and Costs of Minimally Invasive Surgery for Kidney Cancer in the US: A Population-based Study.

OBJECTIVE: To analyze temporal trends and costs associated with the use of minimally invasive surgery (MIS) for kidney cancer in the US over the past decade. To examine the impact of social determinants of health (SDOH) on perioperative outcomes. METHODS: The PearlDiver Mariner, a national database of insurance billing records, was queried for this retrospective observational cohort analysis. The MIS population was identified and stratified according to treatment modality, using International Classification of Diseases and current procedural terminology codes. SDOH were assessed using International Classification of Diseases codes. Negative binomial regression was used to evaluate the overall number of renal MIS and Cochran-Armitage tests to compare the utilization of different treatment modalities, over the study period. Multivariable logistic regression analysis identified predictors of perioperative complications. RESULTS: A total of 80,821 MIS for kidney cancer were included. Minimally invasive partial nephrectomy adoption as a fraction of total MIS increased significantly (slope of regression line, reg. = 0.026, P <.001). Minimally invasive radical nephrectomy ($26.9k ± 40.9k) and renal ablation ($18.9k ± 31.6k) were the most expensive and cheapest procedures, respectively. No statistically significant difference was observed in terms of number of complications (P = .06) and presence of SDOH (P = .07) among the treatment groups. At multivariable analysis, patients with SDOH undergoing minimally invasive radical nephrectomy had higher odds of perioperative complications, while renal ablation had a significantly lower probability of perioperative complications. CONCLUSION: This study describes the current management of kidney cancer in the US, offering a socioeconomic perspective on the impact of this disease in everyday clinical practice.

Genital monkeypox superimposed on co-incident sexually transmitted infections in AIDS patient; a case report.

Monkeypox outbreaks were, until recently, mostly confined to Africa but a currently expanding worldwide outbreak has recently been designated a global emergency by the World Health Organization. Genital manifestation is common and can be confused with sexually transmitted infection (STI), posing a diagnostic challenge. We herein report a case of genital monkeypox superimposed on multiple co-incident STIs in a HIV patient and describe characteristic clinical findings and management.

The monetary costs of pediatric upper urinary tract stone disease: Analysis in a contemporary United States cohort.

INTRODUCTION: The prevalence of upper urinary tract stone disease (USD) in the United States is rising among both adults and children. Studies on the contemporary economic burden of USD management in the pediatric population are lacking. OBJECTIVE: To comprehensively analyze the economic impact of USD in a contemporary United States pediatric cohort, and to evaluate drivers of cost. STUDY DESIGN: A retrospective cohort study of pediatric patients (aged 0-17), diagnosed with USD between 2011 and 2018 were identified from PearlDiver-Mariner, an all-payer claims database containing diagnostic, treatment and prescription data provided in all treatment settings. Relevant International Classification of Disease (ICD-9 and ICD-10) and Current Procedural Terminology (CPT) codes were used for identification, and only patients with claims recorded for at least one year before and after entry of a diagnosis code for USD were selected (N = 10,045). Patients were stratified into those undergoing operative vs. non-operative management and for each patient, total 1-year healthcare costs following USD diagnosis, including same day and non-same day encounters, were analyzed. Factors associated with increased spending, as well as economic trends were analyzed. RESULTS: Overall, 8498 (85%) patients were managed non-operatively, while 1547 (15%) underwent a total of 1880 procedural interventions. Total overall cost was $117.1 million, while median annual expenditure was $15.8 million. Proportion of spending for outpatient, inpatient and prescription services was 52%, 32% and 16%, respectively (Table). Outpatient management accounted for 67% of overall spending. The proportion of patients managed non-operatively increased significantly over time, in parallel with spending for non-operative care. Comorbidity burden, treatment year and geographic region were among predictors of costs. DISCUSSION: Our study is the first to report actual insurance reimbursements for pediatric USD management using actual reimbursement data, examined across all treatment settings. We found that majority of the costs were for outpatient services and for non-operative management, with a rising tendency toward non-operative management over time. Regional variation in expenditures was evident. Specific reasons underlying these observed patterns could not directly be discerned from our dataset, but merit further investigation. CONCLUSION: Non-operative and outpatient management for pediatric USD are increasingly common, resulting in parallel shifts in spending. Notably, 52% of overall spending was for outpatient care. These insights into the contemporary economic burden of pediatric USD could provide value in shaping future healthcare policy.
