Persistent sciatic artery is a rare congenital vascular anomaly that presents with various clinical features, management planning depends on the aneurysmal changes, symptoms, and anatomical features of PSA and SFA. Asymptomatic cases can be managed with observation, while for more complicated cases, surgical or endovascular intervention is needed.

Parvovirus B-19 (B19-PV) infection is usually a self-limiting illness that occurs in children, although there have been reported cases affecting older people and presenting with a wide range of symptoms, especially neurological ones. The diagnosis can be tricky and can cost time; therefore, knowledge of this infectious etiology and how it manifests can aid physicians in prompt and timely diagnosis, as time is vital in such cases in order to preserve organ functions and prevent life-threatening complications. Herein, we report Parvovirus B19-associated clinical features and workup in a series of five patients with laboratory-confirmed B19-PV from 2024 to 2025, which, to our knowledge, is the first case series in the West Bank of Palestine. The mean age of our population was 60.5 years, with a sex ratio (male: female) of 3:2, though of note, males were all above 60 and all females were under 50, mainly presenting with neurological manifestations.

Background: New-onset atrial fibrillation (NOAF) complicates acute myocardial infarction (AMI) and worsens prognosis. Systemic inflammation may contribute, but the value of admission inflammatory biomarkers is uncertain.Methods: Following PRISMA 2020 (PROSPERO CRD420261470060), we searched six databases from inception to 26 September 2026 for observational studies comparing admission neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), or high-sensitivity CRP (hs-CRP) between AMI patients with and without NOAF. Risk of bias was assessed with QUIPS and certainty of evidence with GRADE. We used random-effects models, prediction intervals, leave-one-out sensitivity analyses, and Doi plots with the LFK index.Results: Sixteen studies (12,509 patients; 1,103 with NOAF) were included. NOAF was associated with higher NLR (MD 1.78, 95% CI 0.44 to 3.11; I² 70.6%), CRP (MD 4.17, 1.42 to 6.91; I² 53.8%), and hs-CRP (SMD 0.84, 0.47 to 1.20; I² 88.6%). PLR did not differ significantly (three studies; MD 57.19, 95% CI −13.38 to 127.77). CRP and hs-CRP remained significant in every leave-one-out analysis, whereas NLR lost significance after omitting one study (p = 0.055). All prediction intervals crossed no effect. Funnel plots, Doi plots, and LFK indices (2.46 to 7.25) indicated asymmetry. Certainty of evidence was very low for all biomarkers.Conclusion: Higher admission NLR, CRP, and hs-CRP are associated with NOAF after AMI, but the evidence is very low certainty and PLR findings are inconclusive. These markers cannot yet identify individual high-risk patients; prospective studies with standardized sampling, continuous rhythm monitoring, and adjusted analyses are needed.

Trichohepatoenteric syndrome (THES) is a rare, autosomal recessive disorder characterized by early‐onset diarrhea, woolly hair, and facial dysmorphism and variable multisystem involvement. Herein, we report a 17‐year‐old male with a genetically confirmed THES who presented with worsening diarrhea, fatigability, weight loss, and epigastric pain following intestinal amebiasis. His disease course was notable for extraintestinal and inflammatory manifestations, including chronic recurrent multifocal osteomyelitis, syringomyelia, and inflammatory bowel disease–such as enteropathy, highlighting a broad phenotype. The patient had intractable diarrhea since the age of 2, positive antiendomysial antibodies with no histologic confirmation, and a poor response to standard inflammatory bowel disease therapy. This case highlights the potential role of infectious triggers in precipitating disease flares in THES and demonstrates the diagnostic challenges posed by overlapping clinical and serological features with other autoimmune and inflammatory conditions. Our study broadens the clinical spectrum of THES and emphasizes the importance of detecting infection‐related exacerbations and extraintestinal symptoms in adolescent survivors.

Negative pressure pulmonary hemorrhage (NPPH) is a rare but serious complication following upper airway obstruction, often due to forceful inspiratory efforts. We report a case of a 25-year-old diabetic male who developed sudden hemoptysis and dyspnea after routine varicocelectomy. The patient had likely bitten the endotracheal tube during extubation, causing transient airway obstruction. Imaging showed bilateral pulmonary infiltrates consistent with alveolar hemorrhage. Other causes were excluded, and supportive treatment led to full recovery. This case underscores the importance of recognizing NPPH early in the postoperative period to prevent misdiagnosis and ensure prompt, effective management.

Background: Renal angiomyolipomas (AMLs) are benign renal tumors arising from perivascular epithelioid cells and are often associated with tuberous sclerosis complex. Renal epithelioid angiomyolipoma (EAML) is a rare variant of AML, characterized by the predominance of epithelioid cells with malignant potential. Although EAML is typically seen in adults, especially females, its occurrence in children is extremely rare and can be difficult to distinguish from other renal tumors. Case Presentation: We report a case of an 8-year-old girl with a right renal mass that initially was suspected to be a Wilms tumor based on imaging results and was treated with Wilms-directed chemotherapy without response. Histopathological investigations after a radical nephrectomy revealed an EAML composed primarily of epithelioid cells. Immunohistochemistry confirmed the diagnosis with positive results for HMB45 and Melan-A, highlighting the importance of histopathological and immunohistochemical evaluation in pediatric renal masses with atypical clinical behavior. Conclusion: Renal epithelioid angiomyolipoma should be considered in pediatric renal masses with atypical imaging features or poor response to Wilms tumor chemotherapy. Accurate diagnosis relies on histopathological and immunohistochemical evaluation, which helps guide appropriate surgical management and postoperative surveillance due to the tumor’s variable malignant potential.
