Background: Isolated complex perianal fistulas, without luminal evidence of inflammatory bowel disease in the gastrointestinal tract, pose diagnostic and treatment dilemmas for gastroenterologists and colorectal surgeons. For patients who develop recurrent complex fistulas, a presumptive diagnosis of Crohn's disease may be made. It is unclear whether these cases of isolated perianal disease in the absence of luminal inflammation truly represent isolated severe cryptoglandular fistulas or rather an early presentation of Crohn's disease.

Introduction: Rupture of the flexor carpi radialis (FCR) tendon is a rare phenomenon that is often described in the setting of rheumatoid arthritis or following trauma. Pseudotendon formation is seen commonly among extensor tendons of the antebrachium, typically as a sequelae of traumatic injury, spontaneous rupture in rheumatism, or postoperatively. Less frequent is the presence of pseudotendon in flexor tendons of the forearm.

Pediatric dermatology patients with intellectual and developmental disabilities (IDD) and comorbid cutaneous conditions often face barriers to effective healthcare due to differences in communication preferences and sensitivities to environmental factors. The clinical intake process serves as a potential intervention point to help better understand and meet patients' needs. Strengths-based assessment and considerations around identity-first versus person-first language are tools that can improve the clinical intake process in pediatric dermatology.

Methemoglobinemia is a rare, yet life-threatening disorder that occurs due to an accumulation of methemoglobin in the blood. The clinical presentation often includes dyspnea, cyanosis, and hypoxemia that shows little improvement with the administration of supplemental oxygen. The US Food and Drug Administration (FDA) warns against the administration of benzocaine to those younger than 2 years of age and urges manufacturers to add a statement regarding the possible development of methemoglobinemia to the packaging of any products containing this ingredient.

Article Synopsis
  • There is growing interest in using point of care ultrasound (POCUS) as a teaching tool in medical courses, particularly for cardiac anatomy and physiology; however, few studies have explored team-based learning (TBL) approaches for this topic.
  • This study introduced a novel TBL exercise called Team-Based Learning - Ultrasound (TBL-US) for first-year medical students, comprising phases such as preparation, team readiness, image acquisition, and knowledge assessment, facilitated by trained second-year students.
  • Results showed significant improvements in students’ knowledge of cardiac POCUS and cardiovascular content, with enhanced final exam scores for TBL-US participants compared to non-participants, indicating that this method effectively supports learning in preclinical medical education.

Purpose: To summarize advances in research on the epidemiology, pathogenesis, diagnosis, and treatment of Kawasaki Disease (KD), a systemic inflammatory illness of unknown etiology that affects children globally.

Recent Findings: The epidemiology of KD was affected by the COVID-19 pandemic and advances in molecular immunology and machine learning have enabled research into its pathogenesis. There is ongoing research into agents that can be used to intensify initial treatment and accumulating evidence supporting the use of certain rescue regimens for refractory disease over others.

Identification of a Novel Mesenchymal Stem Cell-Related Signature for Predicting the Prognosis and Therapeutic Responses of Bladder Cancer.

Stem Cells Int

November 2024

Institute of Urology, Key Laboratory of Gansu Province for Urological Diseases, Gansu Urological Clinical Center, Lanzhou University Second Hospital, Lanzhou 730030, China.

Article Synopsis
  • Mesenchymal stem cells (MSCs) show a specific tendency to move towards tumors, impacting cancer growth, treatment resistance, and immune response, prompting research into MSC-related biomarkers for better predicting bladder cancer outcomes.
  • This study used data from TCGA and GSE31684 to identify genes linked to MSCs and created a risk assessment model through advanced statistical analysis techniques.
  • The final prognostic model highlighted five key genes and classified bladder cancer patients into risk categories, revealing that high MSC-risk patients faced worse outcomes and lower responsiveness to immunotherapy and specific chemotherapy drugs compared to low MSC-risk patients.

Background: Mirvetuximab soravtansine-gynx (MIRV) is a first-in-class, folate receptor alpha (FRα)-targeting antibody-drug conjugate with United States Food and Drug Administration approval for FRα-positive platinum-resistant ovarian cancer. PICCOLO is a phase II, global, open-label, single-arm trial of MIRV as third-line or greater (≥3L) treatment in patients with FRα-positive (≥75% of cells with ≥2+ staining intensity) recurrent platinum-sensitive ovarian cancer (PSOC).

Patients And Methods: Participants received MIRV (6 mg/kg adjusted ideal body weight every 3 weeks) until progressive disease (PD), unacceptable toxicity, withdrawal of consent, or death.

Placental mesenchymal dysplasia (PMD), rare vascular and connective tissue placental anomaly can be associated with fetal intrauterine growth restriction (IUGR), stillbirth, Beckwith-Wiedemann syndrome (BWS), some chromosomal abnormalities, or phenotypically and genetically normal fetuses [1]. We reviewed a PMD case from our institution characterized by a previously undescribed chromosomal abnormality along with an unreported histopathologic finding.

Purpose: To predict survival and tumor recurrence following image-guided thermal ablation (IGTA) of lung tumors segmented using a deep learning approach.

Methods And Materials: A total of 113 patients who underwent IGTA for primary and metastatic lung tumors at a single institution between January 1, 2004 and July 14, 2022 were retrospectively identified. A pretrained U-Net model was applied to the dataset of pre- and post-procedure CT scans to segment lung zones.

Intravascular lithotripsy (IVL) is fast becoming the vessel preparation tool of choice given its excellent safety profile and associated positive outcomes. In this review, we aim to summarize the most recent trial data as it applies to IVL's utility within the various peripheral arterial beds, including facilitation of large bore vascular access, and elaborate on future directions of this innovative therapy.

Article Synopsis
  • Plasmodium vivax is increasingly problematic in tropical regions, particularly where Plasmodium falciparum is declining, due to its ability to cause relapse infections that hinder treatment efforts.
  • Researchers developed four specialized molecular inversion probe (MIP) genotyping panels targeting key genetic variations in P. vivax, aiming to better understand its population structure and resistance mechanisms.
  • Analysis using these panels on 866 infections in the Peruvian Amazon revealed significant findings, including transmission networks, gene mutations related to drug resistance, and potential vaccine targets, suggesting these tools can enhance research and control of P. vivax globally.

Introduction Pediatric to adult health care transition (HCT) is critical to maintaining the health and wellness of patients, and pediatric and adult providers often do not feel prepared to shepherd patients through this process. Methods  We designed an HCT curriculum consisting of nine podcasts paired with existing ambulatory experiential learning opportunities for internal medicine-pediatric residents (n=6). Before and after the curriculum we evaluated resident HCT self-assessment and resident performance working with a standardized patient (SP) and standardized parent in a novel objective structured clinical examination (OSCE) station designed to assess HCT skills.
