ABSTRACT
Peripheral artery disease (PAD) affects millions of people worldwide, presenting with varying symptom severity, including chronic total occlusion of arteries, and occasionally, limb amputation. There are various interventions, such as atherectomy and the use of drug-coated balloons and stents, which have been developed to revascularize affected ischemic regions. However, each interventional approach must be individualized due to a patient's unique underlying conditions. Comorbid conditions, especially diabetes, play a significant role in PAD, as poorly controlled diabetes can accelerate PAD progression. For this reason, an early and accurate diagnosis of PAD is crucial, especially when symptoms may present dissimilar to classic PAD symptoms, often leading to misdiagnosis. The presented cases highlight the tailored interventions to revascularize arteries in patients with diabetic foot wounds utilizing catheters, stents, guidewires, and balloons, made possible after early angiogram. These interventions have been promising in treating PAD patients, and highlight the need for early diagnosis and timely and customized interventions to prevent limb amputation and mitigate potential complications.
ABSTRACT
We report the case of a 64-year-old adult male with a rapidly recurring metastatic lung carcinoma in the right atrium of the heart. Advanced-stage lung carcinomas can metastasize to other organs such as the heart, bones, brain, liver, adrenal glands, and lymphatic system, although actual rates of metastasis to the heart are relatively quite low. This patient was diagnosed with a right atrial mass that was determined through pathology to be a result of an existing non-small cell lung carcinoma. This mass, despite resection, reappeared two weeks later at the same location and with a similar size to the previous metastatic tumor. This case highlights the importance of closely monitoring sites of resected tumors for potential regrowth and complications.
ABSTRACT
PURPOSE: Prostate Imaging-Reporting and Data System (PI-RADS) assists in evaluating lesions on multiparametric magnetic resonance imaging (mpMRI), but there are still ongoing efforts in improving the predictive value for the presence of clinically significant PCa (csPCa) with a Gleason grade group ≥ 2 on Fusion-Biopsy. This pilot study intends to propose an easily implementable method for augmenting predictability of csPCa for PI-RADS. METHODS: A cohort of 151 consecutive patients underwent mpMRI Fusion and random US Biopsy as a result of having at least one PI-RADS lesion grade 3-5 between January 1, 2019 and December 31, 2022. A single radiologist reads all films in this study applying PI-RADS V2. RESULTS: Of the 151 consecutive patients, 49 had a highest lesion of PI-RADS 3, 82 had a highest lesion of PI-RADS 4, and 20 had a highest lesion of PI-RADS 5. For each respective group, 12, 42, and 18 patients had proven csPCa. Two predictive models for csPCa were created by employing a logistical regression with parameters readily available to providers. The models had an AUC of 0.8133 and 0.8206, indicating promising effective models. CONCLUSION: PI-RADS classification has relevant predictability problems for grades 3 and 4. By applying the presented risk calculators, patients with PI-RADS 3 and 4 are better stratified, and thus, a significant number of patients can be spared biopsies with potential complications, such as infection and bleeding. The presented predictive models may be a valuable diagnostic tool, adding additional information in the clinical decision-making process for biopsies.

We find minimal literature and lack of consensus among burn practitioners over how to resuscitate thermally injured patients with pre-existing liver disease. Our objective was to assess burn severity in patients with a previous history of liver disease. We attempted to stratify resuscitation therapy utilised, using it as an indicator of burn shock severity. We hypothesized that as severity of liver disease increased, more fluid therapy is needed. We retrospectively studied adult patients with a total body surface area (TBSA) of burn greater than or equal to 20% (n = 314). We determined the severity of liver disease by calculating admission Model for End-Stage Liver Disease (MELD) scores and measured resuscitation adequacy via urine output within the first 24 h. We performed stepwise, multivariable linear regression with backward selection to test our hypothesis with α = 0.05 defined a priori. After controlling for important confounders including age, TBSA, baseline serum albumin, total crystalloids, colloids, blood products, diuretics, and steroids given in first 24 h, we found a statistically significant reduction in urine output as MELD score increased (p < 0.000). In our study, severity of liver disease correlated with declining urine output during first 24-hour resuscitation more so than burn size or burn depth. While resuscitation is standardized for all patients, lack of urine output with increased liver disease suggests a new strategy is of benefit. This may involve investigation of alternate markers of adequacy of resuscitation, or developing modified resuscitation protocols for use in patients with liver disease. More investigation is necessary into how resuscitation protocols may best be modified.

Key Clinical Message: Lymphadenopathy following recent immunization is usually regional. Generalized lymphadenopathy should arouse suspicion for alternative underlying pathology. Prostate adenocarcinoma should be considered in the differential diagnosis for malignancy in an elderly male patient. Metastatic prostate adenocarcinoma can have good prognostic outcomes if treatment is started promptly, even in the setting of widespread disease. Abstract: Generalized lymphadenopathy is commonly attributed to infectious causes or malignancy, often lymphoproliferative disorders. We present a rare case of metastatic prostate cancer diagnosed after initially presenting as generalized lymphadenopathy following a coronavirus disease 2019 (COVID) booster vaccination. A 70-year-old Hispanic male presented with left lower quadrant abdominal pain, nausea, headache, myalgia, severe constipation, and a right-sided neck swelling that had been increasing in size since the day of his vaccination. Computed tomography (CT) scans of soft tissue neck, chest, abdomen, and pelvis with contrast showed extensive lymphadenopathy. Ultrasound-guided biopsy results of the enlarged right supraclavicular node and prostate revealed histopathology consistent with that of prostate acinar adenocarcinoma. He started on bicalutamide for 4 weeks, transitioned to gonadotropin releasing hormone analogue (leuprolide) injections every 3 months and oral androgen receptor signaling inhibitor (abiraterone with prednisone daily). PSA level declined from 121 ng/mL at diagnosis to 1.3 ng/mL after 3 months of therapy, and repeat imaging showed marked improvement in the size of his mediastinal, retroperitoneal, and pelvic lymphadenopathy. To the best of our knowledge, this is the first case reported of a COVID vaccine booster uncovering lymphadenopathy leading to the diagnosis of metastatic prostate cancer.
