In dermatology, they open a new therapeutic field for autoimmune disorders.Objective: To evaluate the mechanisms of action and therapeutic applications of CAR-T cells in autoimmune dermatological diseases, exploring the challenges and future perspectives for their clinical application.Material and methods: A thorough review was conducted in PubMed of preclinical and clinical studies on the application of CAR-T in dermatological diseases, selecting articles from the last 5 years with a focus on autoimmune diseases.Results: The potential of CAR-T cells in autoimmune dermatological diseases is highlighted, such as in pemphigus vulgaris, where CAR-T cells targeting pathogenic anti-Dsg3 B cells have shown efficacy. In cutaneous lupus erythematosus, CAR-T cells directed at CD19 have achieved significant clinical remissions. Additionally, applications in psoriasis and melanoma are explored, although efficacy is limited by adverse factors.Conclusions: CAR-T therapy represents a promising option for the management of refractory dermatological diseases, with favorable results in preclinical and clinical models. However, its clinical implementation faces challenges such as optimizing safety and reducing off-target effects. Future research should focus on next-generation CARs and clinical trials that validate their efficacy and safety profile in dermatology.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6626"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12054643/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143995845","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}

Commonly, cases are asymptomatic and often misdiagnosed as gastrointestinal stromal tumors (GIST) or gastric leiomyomas.Clinical case: A 34-year-old female presented to the clinic for a gastric sleeve for obesity. Preoperatively, there was a GIST misdiagnosis. A CT scan showed a 16 mm gastric tumor in the lesser curvature adjacent to segment III of the liver. Endoscopic ultrasound showed a lesion arising from the muscularis mucosa. The biopsy was positive for spindle cells. The patient underwent a laparoscopic resection and Roux-en-Y gastric bypass. The pathology report showed S100-positive spindle cells compatible with gastric schwannoma.Conclusions: Like our case, gastric schwannomas are usually asymptomatic and arise in middle-aged women. However, their submucosal location in imaging studies, even endoscopic ultrasound, often leads to misdiagnosis. Postoperative pathology and immunohistochemical examinations are critical for final diagnosis and distinguishing features of other malignant stromal cell tumors. Care must be taken in cases with prominent lymph nodes on diagnostic laparoscopy.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6338"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12052381/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144056211","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}

Cases were women with labor that culminated in an emergency cesarean section and controls were women who had a normal vaginal delivery. Clinical history was questioned, and a complete physical examination was performed.

There were differences between groups in maternal weight, obesity, primiparity, uterine activity, history of premature rupture of membranes (PROM), cervical dilatation and effacement (p < 0.05). Factors associated with the risk of cesarean delivery were maternal obesity, primiparity, PROM, dilatation < 6 cm, and effacement < 50% (OR ≥ 3.3).

Digestive bleeding has a multiple etiology; specifically, bleeding from the small intestine accounts for 5 to 10% of gastrointestinal hemorrhages, of which between 0.06% and 5% of cases are caused by diverticula of the small intestine. Most cases are asymptomatic; however, the symptomatic form is highly variable and can present with multiple complications, such as massive bleeding. Therefore, the objective of this study was to explore the approach to jejunal diverticular disease (JDD) with gastrointestinal bleeding.Clinical case: A 48-year-old male patient presented with massive digestive bleeding of unknown origin, initially treated with angiography and embolization, with a satisfactory outcome. However, six days after discharge, the patient experienced new massive bleeding that required an urgent exploratory laparotomy, during which jejunal diverticular disease (JDD) of the small intestine was identified.Conclusions: Diverticula of the small intestine are usually asymptomatic, and complications are rare; however, they can affect the patient's survival. Therefore, an appropriate approach, accurate and timely diagnosis, and a multidisciplinary management strategy are required to offer the best therapeutic options for the patient.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6421"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12057642/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144060080","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}

Recently, evidence has suggested a strong association between EBV and multiple sclerosis (MS). Although EBV infection is common, only a minority of carriers develop MS, indicating the influence of genetic and environmental factors in the pathogenesis. This article reviews the molecular mechanisms through which EBV might influence the development of MS. One mechanism discussed is molecular mimicry, where the similarity between EBV viral antigens and central nervous system proteins could induce a cross-reactive autoimmune response. Additionally, the mechanisms by which EBV evades the immune response are reviewed, including the expression of proteins such as EBNA1 and EBNA2, which interfere with the function of T and NK cells. Genetic factors, such as the HLA-DRB1*15:01 allele, a principal risk factor for MS, are also reviewed. This allele acts as a co-receptor facilitating the infection of B cells by EBV, which could explain the increased susceptibility to MS in individuals with this allele. Furthermore, EBV may alter the epigenetic regulation of genes associated with MS, affecting the expression of key genes in immune response and inflammation. Finally, immunotherapies targeting EBV, such as those based on cytotoxic T lymphocytes, are discussed.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":"63 2","pages":"e6391"},"PeriodicalIF":0.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12054642/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144045586","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}

They were classified into invasive and non-invasive according to Knosp and Hardy classifications by MRI and according to hormonal immunohistochemistry as positive or negative.Results: 50 cases fulfilled the inclusion criteria. 28 adenomas (56%) with positive hormonal immunohistochemistry and 22 adenomas (46%) with negative hormonal immunohistochemistry.
