Specification and guideline for technical aspects and scanning parameter settings of neonatal lung ultrasound examination.

Lung ultrasound (LUS) is now widely used in the diagnosis and monitor of neonatal lung diseases. Nevertheless, in the published literatures, the LUS images may display a significant variation in technical execution, while scanning parameters may influence diagnostic accuracy. The inter- and intra-observer reliabilities of ultrasound exam have been extensively studied in general and in LUS.

Application of modified closed biopsy in rabbit model of VX2-transplanted bone tumor.

Background: This study was aimed to explore the application value of modified closed biopsy technique in puncture biopsy of rabbit VX2 transplanted bone tumor model.

Methods: VX2 tumor was transplanted into the bilateral tibia of 30 rabbits through the tibial plateau to make the model of VX2 transplanted bone tumor. Seven days after modeling, the proximal tibia biopsy was performed under the guidance of X-ray, and the biopsy specimen was examined pathologically.

International Expert Consensus and Recommendations for Neonatal Pneumothorax Ultrasound Diagnosis and Ultrasound-guided Thoracentesis Procedure.

Pneumothorax (PTX) represents accumulation of the air in the pleural space. A large or tension pneumothorax can collapse the lung and cause hemodynamic compromise, a life-threatening disorder. Traditionally, neonatal pneumothorax diagnosis has been based on clinical images, auscultation, transillumination, and chest X-ray findings.

Protocol and Guidelines for Point-of-Care Lung Ultrasound in Diagnosing Neonatal Pulmonary Diseases Based on International Expert Consensus.

Ultrasound is a safe bedside imaging tool that obviates the use of ionizing radiation diagnostic procedures. Due to its convenience, the lung ultrasound has received increasing attention from neonatal physicians. Nevertheless, clear reference standards and guideline limits are needed for accurate application of this diagnostic modality.

A ligand-based and enediyne-energized bispecific fusion protein targeting epidermal growth factor receptor and insulin-like growth factor-1 receptor shows potent antitumor efficacy against esophageal cancer.

Recent studies have revealed that the epidermal growth factor receptor (EGFR) and insulin-like growth factor-1 receptor (IGF-1R) are overexpressed in various types of human tumors and are attractive targets for anticancer drugs. In the present study, the expression of EGFR and IGF-1R in esophageal squamous cell carcinoma (ESCC) and adjacent normal tissues in a tissue microarray was firstly detected by immunohistochemical staining. In addition, their co-overexpression was observed in 48 out of 75 (64%) patients.

A bispecific enediyne-energized fusion protein targeting both epidermal growth factor receptor and insulin-like growth factor 1 receptor showing enhanced antitumor efficacy against non-small cell lung cancer.

Epidermal growth factor receptor (EGFR) and insulin-like growth factor 1 receptor (IGF-1R) both overexpressed on non-small cell lung cancer (NSCLC) and are known cooperatively to promote tumor progression and drug resistance. This study was to construct a novel bispecific fusion protein EGF-IGF-LDP-AE consisting of EGFR and IGF-IR specific ligands (EGF and IGF-1) and lidamycin, an enediyne antibiotic with potent antitumor activity, and investigate its antitumor efficacy against NSCLC. Binding and internalization assays showed that EGF-IGF-LDP protein could bind to NSCLC cells with high affinity and then internalized into cells with higher efficiency than that of monospecific proteins.

Lung ultrasonography to diagnose meconium aspiration syndrome of the newborn.

Objective To investigate the diagnostic value of lung ultrasonography for neonatal meconium aspiration syndrome (MAS). Methods This prospective observational study enrolled patients diagnosed with MAS based on medical history, clinical manifestations and chest X-ray and control newborns without MAS. During ultrasonography, each lung was divided into three regions (front, lateral, and back), using anterior and posterior axillary lines as the boundary.

The significance and the necessity of routinely performing lung ultrasound in the neonatal intensive care units.

Various lung diseases are the most common conditions and the leading cause of hospital admission and death in newborns. Historically, the diagnosis and differential diagnosis of lung diseases primarily relied on conventional chest X-ray and computed tomography (CT) scans, however, chest X-ray and CT scans suffer from obvious limitations, while lung ultrasound has many kinds of advantages for the diagnosis and differential diagnosis of lung diseases. The significance and the necessity of lung ultrasound in the diagnosis of neonatal lung diseases will be introduced in this paper.

The Role of Lung Ultrasound in Diagnosis of Respiratory Distress Syndrome in Newborn Infants.

Background: Respiratory distress syndrome (RDS) is one of the most common causes of neonatal respiratory failure and mortality. The risk of developing RDS decreases with both increasing gestational age and birth weight.

Objectives: The aim of this study was to evaluate the value of lung ultrasound in the diagnosis of respiratory distress syndrome (RDS) in newborn infants.

The role of lung ultrasound in diagnosis of respiratory distress syndrome in newborn infants.

Objective: The aim of this study was to evaluate the value of lung ultrasound in the diagnosis of respiratory distress syndrome (RDS) in newborn infants.

Methods: From March 2012 to May 2013, 100 newborn infants were divided into two groups: RDS group (50 cases) and control group (50 cases). According to the findings of chest x-ray, there were 10 cases of grade II RDS, 15 grade III cases, and 25 grade IV cases in RDS group.

[Lung ultrasonography for the diagnosis of neonatal respiratory distress syndrome: a pilot study].

Objective: The diagnosis of respiratory distress syndrome (RDS) is usually based on clinical manifestations, arterial blood gas analysis and chest x-ray. Lung ultrasounds are typically not included in the diagnostic work-up of neonatal RDS. Recently, ultrasounds have been used extensively and successfully in the diagnosis of many kinds of lung diseases, but few studies have addressed neonatal RDS.

The pattern and early diagnostic value of Doppler ultrasound for neonatal hypoxic-ischemic encephalopathy.

This article investigates the value of early diagnosis and prognostic evaluation of Doppler ultrasound for neonatal hypoxic-ischemic encephalopathy (HIE). Study population included 40 term neonates with HIE and 30 healthy controls. Color Doppler ultrasound was performed at the bedside within 24 h after birth.
