Article Abstract

Introduction: Venous malformations are the most common congenital vascular anomaly, accounting for 65 % of all congenital vascular abnormalities. This study aims to investigate the correlation between genetic polymorphisms of and the risk of developing venous malformations.

Methods: We collected samples and clinical data from a Chinese pediatric population (1113 patients and 1158 controls). Using real-time quantitative PCR, we performed TaqMan genotyping on rs591291 C > T and rs3200401 C > T polymorphisms and further analyzed the data through statistical methods.

Results: Sequencing results and analysis indicate that the rs591291 C > T and rs3200401 C > T polymorphisms are not significantly correlated with the risk of venous malformation. When combined both genotypes also present no statistic difference in increased risk of developing these anomalies (odds ratio = 0.90, 95 % confidence interval = 0.72-1.13,  = 0.354). Stratified analysis of different subtypes of venous malformations revealed that there was no statistic difference in the selected polymorphisms of across these subtypes.

Conclusion: Our findings suggested that rs591291 C > T and rs3200401 C > T polymorphisms were not correlated to the risk of venous malformation in the Chinese pediatric population.

Aim Of The Study: To present a case series of four pediatric patients with PDPV, each with a different clinical presentation and surgical management.

Methods: We retrospectively reviewed four cases of PDPV managed at our institution. Two cases were associated with extrahepatic biliary atresia (EHBA) and discovered incidentally during surgery.

Background: Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant disorder characterized by abnormal vascular formations across multiple organ systems, including the brain. While arteriovenous malformations (AVMs) are well recognized in HHT, non-AVM cerebrovascular malformations remain underreported and poorly understood manifestations of the disease.

Methods: A systematic review was conducted using multiple databases, applying a two-step screening process to exclude studies with insufficient, irrelevant, or incomplete data.

Widespread fragmentation shells in combat operations with frequent multiple damage to organs and systems force to use all available diagnostic methods for treating severe injuries including lesion of great vessels of extremities. One of the consequences of these lesions is arteriovenous fistula (AVF). The last one may be asymptomatic at first.

Background: Turner syndrome (TS), also known as congenital ovarian hypoplasia, is one of the most common sex chromosome diseases in women. It is caused by the complete or partial deletion or structural change of one X chromosome in all or part of somatic cells. A rare case of karyotype Turner syndrome is reported.

Background: Although some studies have indicated that CDK4/6 inhibitors are beneficial for the progression-free survival (PFS) and overall survival (OS) in breast cancer, evidence regarding the assessment of clinical response remains insufficient. Therefore, this study aims not only to evaluate the efficacy and safety of CDK4/6 inhibitors combined with endocrine therapy in HR(+)/HER2(-) metastatic breast cancer, but also to analyze the objective response rate (ORR) and clinical benefit rate (CBR), providing comprehensive clinical outcome insights.

Materials And Methods: A literature search was performed in PubMed, Embase, Cochrane Library, and ClinicalTrials.
