Cytomegalovirus Retinitis in an Eye with Unilateral Retinoblastoma: A Case Report.

Introduction: Cytomegalovirus (CMV) retinitis in the setting of pediatric retinoblastoma is exceedingly unusual. Here, we present the first reported case of CMV retinitis in an enucleated eye with retinoblastoma after chemotherapy in the western hemisphere. Case Presentation: A 2-year-old Hispanic male without a family history of retinoblastoma presented with a 3-month history of right eye exotropia and squinting. Clinical examination revealed dense white vitreous opacities in the right eye. Ocular oncology evaluation unveiled an exudative retinal detachment with vitreous seeds, subretinal seeding, and a tumor emanating from the retina in the superonasal quadrant of the right eye. The patient was diagnosed with unilateral Group D retinoblastoma, and RB1 sequencing revealed a pathogenic variant with mosaicism. Treatment involved systemic chemotherapy, intravitreal chemotherapy, and cryotherapy. However, the patient developed a rhegmatogenous retinal detachment with diffuse vitreous hemorrhage and ultimately underwent right eye enucleation. Interestingly, histopathological analysis of the enucleated eye revealed concomitant CMV retinitis alongside retinoblastoma. After consultation with infectious disease, antiviral treatment was not initiated as the patient remained asymptomatic and maintained a recovered immune system. Repeat CMV PCR confirmed viral clearance. The patient received a prosthetic eye and continues to be monitored for retinoblastoma recurrence. Conclusion: Clinicians should be aware of the potential for CMV retinitis to develop in retinoblastoma patients receiving chemotherapy, which may complicate clinical decision-making and management. Timely identification of CMV retinitis in this setting may improve patient ocular outcomes and overall prognosis.

Molecular profiling of renal cell carcinoma presenting as iris metastasis.

Purpose: To describe a case of iris metastasis as the initial presentation of clear cell renal cell carcinoma, and to discuss molecular profiling of both the metastasis and primary kidney tumor. Observations: We report a patient with blurred vision who underwent ophthalmic examination and was found to have an iris mass, which was excised and diagnosed as a metastatic clear cell renal cell carcinoma by morphology and immunohistochemical analysis. As a result of the pathology findings, computed tomography imaging was performed, revealing a right kidney mass, which was also resected and shown to represent a high-grade carcinoma confined within the renal fascia without lymphovascular invasion. Molecular testing of the primary and metastatic tumors using a custom next-generation sequencing panel revealed similar mutational profiles but disclosed a TERT promoter mutation in the primary neoplasm, not present in the metastasis, suggesting seeding of an early lower grade neoplastic cell clone within the iris. Conclusions and importance: This report illustrates how pathological examination of a small iris lesion led to the discovery of a previously unknown systemic malignancy at a resectable stage. Molecular genetic profiling revealed that even lower grade clones within a high-grade neoplasm have metastatic potential.

Clinical Features and Multimodal Imaging in Atypical Posterior Uveitis Secondary to Bartonella Henselae Infection.

PURPOSE: To characterize an unusual presentation of infectious posterior uveitis using multimodal imaging, and discuss the clinical decision-making involved in diagnosis and treatment. METHODS: Wide-field fundus photography, swept-source optical coherence tomography (OCT), swept-source OCT angiography, fluorescein angiography, and indocyanine green angiography. RESULTS: This patient presented with cyclical fevers and blurry vision. Fundus examination revealed bilateral optic disc edema, macular intraretinal white spots and many scattered yellow-white chorioretinal lesions. Multimodal imaging characteristics suggested that many of these lesions represent choroidal granulomas. Extensive systemic workup was only notable for borderline elevated Bartonella henselae IgG titers (1:128), however convalescent IgG titers were elevated at 38 days (1:512) supporting the diagnosis of Bartonella chorioretinitis. CONCLUSION: Ocular manifestations of Bartonella henselae infection are varied and may include choroidal granulomas. Multimodal imaging characteristics may help identify etiologies of infectious uveitis. Convalescent titers are important when evaluating patients with suspected Bartonellosis, especially patients with atypical presentations.

How well did our students match? A peer-validated quantitative assessment of medical school match success: the match quality score.

Background: Assessment of an individual medical school's performance in the match is an important outcome of the educational program. Unfortunately, student rank lists are not public. A method to objectively gauge the quality of an institution's match regardless of student preference has not been described in the literature.Objective: This manuscript serves to determine the relative weights of included variables and derive a statistically valid Match Quality Score (MQS).Design: Between 2016 and 2018, student affairs experts derived from a national cohort validated the MQS by scoring factitious mini-match lists that covered three variables: student's Match Status, specialty Competitiveness, and residency program Reputation.Results: Of the variables assessed, only Match Status and Competitiveness were found to be significant. We derived the resulting coefficients for the Match Quality Score (MQS) as: [3.74A (# students successfully matched) + 2.34B (# students matching into their initial specialty in the SOAP process) + 1.77C (# students who secured a SOAP position in another specialty) + 0.26D (# students matching into a specialty where there are more applicants than spots)]/Total # students.Conclusions: The MQS is a potentially useful educational outcome measurement for US medical schools and may be considered as an outcome measure for continuous quality improvement to tailor future institutional changes to training, mentoring, and student-advising programs.
