Purpose: The determine the usefulness of urinalysis in monitoring patients with distal ureterolithiasis.
Materials And Methods: Patients with microhematuria who were found to have a distal ureteral stone and who were candidates for conservative management were enrolled in the study. Patients were typically seen in clinic at 1 to 2 weeks after initial diagnosis and reassessed. A urinalysis, including office dipstick and automated laboratory analysis using the IQ 200 IRIS analyzer, were performed. The absence or presence of microhematuria was determined and compared with results of repeated unenhanced helical CT of the abdomen and pelvis to determine the sensitivity, specificity, and positive and negative predictive values of urinalysis.
Results: Twenty-nine patients were enrolled in this prospective study. The mean age of the patients was 43.5 years. The sex distribution was predominantly male, with 72% men and 28% women. Ultimately, 18 patients are included in our analysis with the remainder either lost to follow-up or excluded because of protocol violation. Average distal stone size was 4.1 mm (range 2.0-6.5 mm). Stones were evenly distributed between the right and the left ureters, with 50% on either side. Mean time to follow-up was 18 days with a range of 2 to 63 days. The sensitivity of urinalysis was determined to be 40% (8%-72%) while the specificity was 63% (28%-98%). The predictive value of a positive test was 57% (19%-95%) and the predictive value of a negative test was 55 % (25%-85%). The confidence interval for each of these parameters is inclusive of the value of 50%, indicating that urinalysis is no better than randomness in predicting presence or absence of a stone by CT.
Conclusions: The absence or presence of microhematuria does not accurately predict whether a distal ureteral stone has passed or is still present. In those patients who need or want to know whether a stone is still present, unless a stone is strained, we suggest repeated CT imaging.

We describe a 54-year-old man with type 2 diabetes mellitus, ischemic myopathy, pulmonary hypertension, and end-stage renal disease who was admitted for heart failure and listed for a dual cardiac-renal transplantation. Extensive calcification in the iliac arteries prevented clamping. Proximal endovascular balloon control of the left iliac artery was achieved using contralateral access; distal control was established by passing a Fogarty catheter distally through an iliac arteriotomy, later used for anastomosis of the cadaveric conduit.

Introduction: Advanced penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy with a poor prognosis and an unmet need for biomarkers. We performed a retrospective evaluation of real-world efficacy, safety outcomes, and baseline inflammatory biomarkers in patients with advanced pSCC treated with immune checkpoint inhibitors (ICIs).
Methods: We performed a retrospective review of patients with advanced pSCC who received ICIs from 2012 to 2023 at the Winship Cancer Institute of Emory University in Atlanta, GA.
Eruptive pseudoangiomatosis (EP) is a rare cutaneous condition that usually resolves spontaneously within a few days and is more frequently seen in the pediatric age group. It is characterized by the sudden onset of asymptomatic small erythematous hemangioma-like papules encircled by a pale halo. The precise pathogenesis is unknown; however, multiple environmental triggers have been reported.

Jaffe-Campanacci syndrome (JCS) is a rare disorder characterized by multiple non-ossifying fibromas (NOFs), café-au-lait spots, and other features such as mental retardation and cryptorchidism. It is often clinically and genetically similar to neurofibromatosis type 1 (NF1), complicating diagnosis. This report presents a 17-year-old male with right knee pain, café-au-lait spots, and axillary freckling.

Osteosarcoma (OS) is the most common malignant bone tumor affecting adolescents and young adults and it usually occurs in the long bones of the extremities. The detection of cancer-related genetic alterations has a growing effect in guiding diagnosis, prognosis and targeted therapies. However, little is known about the molecular aspects involved in the etiology and progression of OS, which limits options for targeted therapies.
