OBJECTIVES: To compare the complications associated with age and technique groups in patients undergoing pectus excavatum (PE) repair. METHODS: The data of 994 patients who underwent PE repair from March 2011 to December 2015 were retrospectively reviewed. Mean age was 9.59 years (range 31 months-55 years), and 756 patients were men (76.1%). The age groups were defined as follows: Group 1, <5 years; Group 2, 5-9 years; Group 3, 10-14 years; Group 4, 15-17 years; Group 5, 18-19 years; Group 6, 20

OBJECTIVES: Lung cancer treatment in patients with chronic lung diseases is challenging because postoperative care is difficult and surgical outcomes are poorer than in patients with healthy lungs. This study aimed to examine postsurgical outcomes of patients with comorbid lung diseases treated for lung cancer. METHODS: This retrospective study enrolled 1526 patients who underwent curative surgical resection for non-small-cell lung cancer at a single centre between October 2008 and April 2017. B

In LUAD, low JAK2 expression linked to the presence of STAS might serve as an unfavorable prognostic factor. A relationship between JAK2 and CD8+ T cells suggests that STAS is indirectly related to the anticancer immune response. These results may contribute to the design of future experimental research and drug development programs for LUAD with STAS.

Background Determining brain atrophy is crucial for the diagnosis of neurodegenerative diseases. Despite detailed brain atrophy assessments using three-dimensional (3D) T1-weighted magnetic resonance imaging, their practical utility is limited by cost and time. This study introduces deep learning algorithms for quantifying brain atrophy using a more accessible two-dimensional (2D) T1, aiming to achieve cost-effective differentiation of dementia of the Alzheimer’s type (DAT) from cognitively unim

therapy like pirfenidone in idiopathic pulmonary fibrosis or postoperative prophylactic non-invasive ventilation or other measures to reduce postoperative pulmonary complications and acute respiratory failure were used is missing.

NSCLC lesions 3 cm or smaller that abut adjacent structures present higher rates of various risk factors than non-abutting lesions, necessitating evaluation of tumor invasion into adjacent structures and lymph node metastasis. In isolation, however, the presence of tumor abutment without visceral pleural invasion does not constitute a risk factor.

Abstract Background If a clinician encounters a foreign body in thoracic esophagus, flexible endoscopy is the first treatment modality that comes up in mind. But if the foreign body is too huge to pass the upper esophageal sphincter or stuck in esophageal wall, removal is not easy and could result in iatrogenic injury. Furthermore, esophageal perforation is clinically fatal situation and mandates prompt surgical intervention. Here, we report our successful single step treatment of esophageal per

Sacrococcygeal teratoma is the most common tumor in the fetus and neonates. It is often diagnosed by ultrasonography (USG) in the prenatal period. Recently, fetal MRI may be helpful in assessing the exact tumor size, content, and intra-abdominal extent to optimize prenatal and postnatal management. We describe a case of sacrococcygeal teratoma (type II) diagnosed by prenatal USG and fetal MRI which was treated surgically with good result. A pregnant woman with 32 + 3 weeks of gestation was trans
