This diagnostic challenge and low clinical recognition can delay targeted treatment, increasing morbidity and mortality. Although there have been advances in understanding porphyrias' biochemical pathways, improved diagnostic approaches are still needed, especially in acute care. This study examined diagnostic and clinical patterns of acute hepatic porphyria at a quaternary care hospital in Bogotá, Colombia, to support earlier detection and management.Materials and MethodsThis descriptive, observational, retrospective study reviewed patients diagnosed with acute hepatic porphyria at the Internal Medicine service of a Bogotá hospital from 2013 to 2023. Patients with confirmed diagnoses recorded in the hospital database were included. Data collected covered demographic characteristics, clinical presentation, diagnostic markers, and treatment. Key outcome measures were time to diagnosis, recurrence frequency, and hospitalization duration.ResultsTen patients were included, 80% of whom were female, with a median age of 32 years. Diagnosis was confirmed by urine porphobilinogen tests. All patients reported abdominal pain during attacks; 90% had tachycardia and paresis/weakness of extremities. Attack durations ranged from 4 to 11 days, with 90% treated with hemin. Median hospital stay was 18 days. Drug use and infections were common precipitants, and 40% of female patients had premenstrual-associated attacks.ConclusionsThis study provides a clinical profile of acute hepatic porphyria in a Colombian hospital, highlighting neurovisceral symptoms and female predominance. Findings suggest the need for early diagnostic protocols to prevent treatment delays, although larger studies are required to confirm these findings across different settings.</p>","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 3","pages":"3000605251325183"},"PeriodicalIF":1.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11930460/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Basic patient information and perioperative variables were evaluated as risk factors for meningitis. Univariate and multivariate analyses were performed to identify the risk factors for postoperative meningitis.ResultsOverall, 47 (5.0%) of the 937 patients were infected with postoperative meningitis. Univariate analysis revealed that albumin level (<3.5 mg/dL; p = 0.017), preoperative hospitalization (median: 4 days; interquartile range: 2-6 days; p = 0.034), tumor location (skull base; p < 0.001), surgery duration (>3 h; p < 0.001), and bleeding volume during operation (≥400 mL; p < 0.001) were significantly associated with postoperative meningitis following resection of meningioma. The average postoperative hospital stay in the postoperative meningitis group was 14 days, whereas it was 6 days in the nonpostoperative meningitis group (p < 0.001). Furthermore, multivariate analysis showed that tumor location (skull base; p = 0.004; odds ratio = 2.914; 95% confidence interval: 1.395-6.091), surgery duration (>3 h; p = 0.006; odds ratio = 3.024; 95% confidence interval: 1.370-6.674), and bleeding volume during operation (p = 0.034; odds ratio = 2.057; 95% confidence interval: 1.056-4.006) were independent risk factors for postoperative meningitis following resection of meningioma.ConclusionTumor location (skull base), longer surgery duration (>3 h), and higher bleeding volume during operation (≥400 mL) were independent risk factors for postoperative meningitis following resection of meningioma. Moreover, postoperative meningitis was associated with a prolonged hospital stay. These findings can help identify patients with meningioma in need of special intervention to prevent postoperative meningitis and can help surgeons preoperatively identify the risk of postoperative meningitis for meningioma.</p>","PeriodicalId":16129,"journal":{"name":"Journal of International Medical Research","volume":"53 3","pages":"3000605251327527"},"PeriodicalIF":1.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11951431/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143719834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although not always a concern, pregnancy-related vaginal bleeding may detrimentally impact maternal and fetal health, and can arise at any stage during the pregnancy, usually linked with preterm labor, miscarriage, placental abnormalities, or implantation bleeding. As vaginal bleeding may compromise newborn health outcomes, for example, leading to low birth weight and neonatal intensive care unit (NICU) hospitalizations, it is imperative to understand the etiology of the bleed and effectively manage the patient's condition.
