Although disease progression can involve the lung parenchyma, pulmonary carcinomatous lymphangitis is an exceptionally rare manifestation. Up until the date of this publication, evidence in literature is limited, highlighting the rarity of this pattern of dissemination and the importance of its timely recognition.Clinical case: A 72-year-old man with initial macroscopic hematuria, who was diagnosed with nested variant of urothelial carcinoma with infiltration of the lamina propria. Despite transurethral resection of the tumor and subsequent systemic treatment with platinum-based chemotherapy, the patient experienced rapid disease progression, which was characterized by pelvic and mediastinal lymph node infiltration, pulmonary lymphangitic dissemination, bilateral hydronephrosis, and thrombosis of the right internal jugular vein, as well as the left common iliac, external iliac, and femoral veins.Conclusions: This report documents a case of muscle invader nested variant of urothelial carcinoma, whose evolution was complicated by pulmonary carcinomatous lymphangitis, an extremely rare manifestation. Early recognition of this variant is essential to guide the diagnostic and therapeutic approach in patients with high-risk histological variants.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"64 5","pages":"e7099"},"PeriodicalIF":0.0,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13614675/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effect measures are essential tools for quantifying the true magnitude of an intervention and assessing its clinical impact. However, limited understanding of these measures among healthcare professionals often hinders the effective translation of evidence into everyday practice. This article's objective is to provide a clear and didactic overview of the principal effect measures used in clinical research, emphasizing their relevance to evidence-based medicine. Key concepts such as the p-value, confidence intervals, relative risk, absolute risk reduction, and number needed to treat are summarized. The p-value reflects statistical significance, but it does not convey the magnitude or clinical importance of an effect. Confidence intervals, on the other hand, offer information about the precision and direction of the estimated effect. Relative risk facilitates the comparison of probabilities between groups, while absolute risk reduction and number needed to treat provide more tangible measures for clinical application. The adequate interpretation of these concepts is a cornerstone of evidence-based medicine, it enables clinicians to critically appraise research findings, and make patient-centered decisions, thereby narrowing the gap between scientific evidence and clinical practice.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"64 5","pages":"e6907"},"PeriodicalIF":0.0,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13600739/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149027293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This plan aims to strengthen IMSS operational capacities and to reorient processes and services in order to provide an appropriate response to the specific needs of this population group, thereby improving medical care for older beneficiaries. GeriatrIMSS is based on 4 fundamental pillars: prevention (PREVENIMSS), comprehensive geriatric care, education, and research. Through this strategy, IMSS positions itself at the international forefront of older adult care, addressing the main health challenges faced by this population and providing preventive, comprehensive, and interdisciplinary care.

The clinical spectrum ranges from asymptomatic presentation to pulmonary hypertension and heart failure in the neonatal period.Clinical case: 2-month-old breastfed infant with anomalous origin of the right pulmonary artery from the ascending aorta, initially suspected due to the presence of a cardiac murmur and a positive cardiac screening. Echocardiography and computed tomography angiography confirmed the diagnosis, showing no stenosis of the anomalous branch and no significant pulmonary hypertension as estimated by non-invasive methods. Surgical reimplantation was performed with anastomotic enlargement using bovine pericardium. The postoperative course was complicated by transient respiratory issues, with a favorable clinical outcome.Conclusions: This case supports the usefulness of echocardiography and computed tomography angiography as tools for accurate anatomical diagnosis and based on each individual case for planning treatment.

Certain dermoscopic features allow differentiation from other pigmented lesions and assessment of its evolution. We report a case of CMN with melanocytic distribution limited to hair follicles, associating dermoscopic findings with reflectance confocal microscopy (RCM).Case report: A 2 year and 7 month old male patient with no relevant medical history presented with a 10 × 7 mm melanocytic macule on the left posterior lumbar region, present since birth. Dermoscopy revealed a central gray-blue area with dark brown globules distributed perifollicularly and radially from the follicular ostium, forming a \"sky full of stars\" pattern. RCM showed melanocytic proliferation at the dermoepidermal junction, organized in dense aggregates and nests, with a mixed mesh and globular pattern.Conclusions: Perifollicular aggregates observed on dermoscopy correspond to melanin deposits within follicular openings. The \"sky full of stars\" pattern, which has been rarely described, may be associated with melanocytes confined to the infundibulum and noncontiguous hair follicles. It is important to differentiate this pattern from the globular pattern, which indicates melanocytic activity.
