Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.

Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.

Background: He's team have recently developed a new Coronary Artery Tree description and Lesion EvaluaTion (CatLet) angiographic scoring system, which is capable of accounting for the variability in coronary anatomy, and risk-stratifying patients with coronary artery disease. Preliminary studies have demonstrated its superiority over the the Synergy between percutaneous coronary intervention with Taxus and Cardiac Surgery (SYNTAX) score with respect to outcome predictions for acute myocardial infarction (AMI) patients. However, there are fewer studies on the prognostic in chronic coronary artery disease(CAD).

Background: The pathogenesis of chronic obstructive pulmonary disease (COPD) is not fully understood. This work aimed to demonstrate the role of serum free light chains (sFLC) in the pulmonary inflammatory response of COPD patients and its relationship with serum inflammatory cytokine (IC) levels.

Methods: Eighty subjects were enrolled, including 40 COPD patients (COPD group) and 40 healthy controls (control group).

Background: To investigate the changes of b2-microglobulin and electrolyte in different stages of chronic obstructive pulmonary disease (COPD) and the value of evaluating prognosis.

Methods: A retrospective study was undertaken on 120 patients diagnosed with COPD and treated at our respiratory department between February 1, 2020, and January 31, 2023. These patients were classified into three groups based on the GOLD classification: mild (FEV1 > 81%), moderate (51% < FEV1 ≤ 80%), and severe (FEV1 ≤ 50%).

Superior vena cava obstruction following pericardial effusion absorption in the presence of a pericardial teratoma: a case report.

J Cardiothorac Surg

January 2025

Department of Cardiac Surgery, Children's Hospital Affiliated Shandong University Jinan Children's Hospital, No. 23976, Jingshi Road, Huaiyin District, Jinan City, Shandong Province, China.

Intrapericardial teratoma is a rare tumor that usually presents in neonates or during infancy because of the associated high degree of pericardial effusion, cardiac compression and severe respiratory distress. In this paper, we report a rare case of intrapericardial teratoma that was incidentally discovered in an infant with superior vena cava obstruction following pericardial effusion absorption. Echocardiography and thoracic computed tomography angiography revealed that the intrapericardial mass obviously suppressed the superior vena cava.
