Background: Missed injury of the diaphragm may result in hernia formation, enteric strangulation, and death. Compounding the problem, diaphragmatic injuries are rare and difficult to diagnose with standard imaging. As such, for patients with high suspicion of injury, operative exploration remains the gold standard for diagnosis. Read More

Background: The present study aimed to characterize the behavior of 3 components of respiratory muscle function during mechanical ventilation weaning in children to better understand the respective impact of a spontaneous breathing trial on ventilatory mechanical action (esophageal pressure [P], ventilatory demand (electrical activity of the diaphragm [EA]), and oxygen consumption.
Methods: This was a prospective single-center study. All children ≥ 1 months and <18 y old who were intubated and on mechanical ventilation, and who were hospitalized in the pediatric ICU were eligible. Read More

We report performing a successful arterial switch operation on a full-term male infant with transposition of the great arteries and intact ventricular septum associated with a congenital diaphragmatic hernia. The patient developed severe persistent pulmonary hypertension after successful repair of a left congenital diaphragmatic hernia that restricted pulmonary blood flow into the hypoplastic left lung, and subsequent unilateral pulmonary congestion of the unaffected right lung occurred because of the hemodynamics generated by the transposition of the great arteries. Intravenous epoprostenol with nitric oxide inhalation and mechanical hypoventilation effectively controlled pulmonary vascular resistance before the arterial switch operation was performed. Read More

Oculopharyngeal muscular dystrophy (OPMD) is an uncommon autosomal dominant disorder that has been characterized by slow progression. Neuromuscular disease is one of several etiologies of pulmonary volume restriction from extrinsic or parenchymatous causes and can lead to pulmonary hypertension and right-sided heart failure, which is consistent with cor pulmonale. Here we describe a case of an OPMD patient with cor pulmonale that was reversed using mechanically-assisted ventilation. Read More

Introduction: Persistent pulmonary hypertension (PPH) is a major cause of morbidity and mortality in newborns with congenital diaphragmatic hernia (CDH). PPH is characterized by increased vascular resistance and smooth muscle cell (SMC) proliferation, leading to obstructive changes in the pulmonary vasculature. Nitric oxide (NO), generated by endothelial NO synthase (eNOS), is an important regulator of vascular tone and plays a key role in pulmonary vasodilatation. Read More

Introduction: Although pain facial assessment is routinely performed in term and preterm newborns by the use of facial expression-based tools such as the Neonatal Facial Coding System, the assessment of pain during the intrauterine life has not been extensively explored.
Objective: Describe for the first time, an experimental model to assess and quantify responses due to acute pain in fetuses undergoing anaesthesia for intrauterine surgery recorded by high-resolution 4D ultrasound machines.

Abdominal pain with elevated transaminases from inferior vena cava (IVC) obstruction is a relatively common reason for referral and further workup by a hepatologist. The differential for the cause of IVC obstruction is extensive, and the most common etiologies include clotting disorders or recent trauma. In some situations the common etiologies have been ruled out, and the underlying process for the patient's symptoms is still not explained. Read More

Congenital diaphragmatic hernia (CDH) is a severe birth defect that is often accompanied by other congenital anomalies. Previous exome sequencing studies for CDH have supported a role of de novo damaging variants but did not identify any recurrently mutated genes. To investigate further the genetics of CDH, we analyzed de novo coding variants in 362 proband-parent trios including 271 new trios reported in this study. Read More

Purpose Of Review: Diaphragm dysfunction is common in mechanically ventilated patients and predisposes them to prolonged ventilator dependence and poor clinical outcomes. Mechanical ventilation is a major cause of diaphragm dysfunction in these patients, raising the possibility that diaphragm dysfunction might be prevented if mechanical ventilation can be optimized to avoid diaphragm injury - a concept referred to as diaphragm-protective ventilation. This review surveys the evidence supporting the concept of diaphragm-protective ventilation and introduces potential routes and challenges to pursuing this strategy. Read More

Glucocorticosteroids are the most efficacious anti-inflammatory agents and the gold standard treatment in Duchenne muscular dystrophy (DMD). However, their chronic use may lead to severe side effects. We evaluated the use of a novel injectable steroidal nano-drug in mdx mouse model of DMD by comparing the efficacy of nano-liposomes remotely loaded with the steroid prodrug, methylprednisolone hemisuccinate (MPS) with the same steroid as-is, in short (4-weeks) and long-term (58-weeks) treatments.

Amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting motor neurons, is characterized by rapid decline of motor function and ultimately respiratory failure. As motor neuron death occurs late in the disease, therapeutics that prevent the initial disassembly of the neuromuscular junction may offer optimal functional benefit and delay disease progression. To test this hypothesis, we treated the SOD1 mouse model of ALS with an agonist antibody to muscle specific kinase (MuSK), a receptor tyrosine kinase required for the formation and maintenance of the neuromuscular junction.

Diaphragmatic eventration in old age is a rare phenomenon. Typically, it is thought to originate as a result of failure of development of the muscles of the diaphragm. Less commonly, it can occur secondary to acquired conditions resulting from spinal cord or phrenic nerve injury and is only detected incidentally when the patient presents with dyspnea, chest infection, or cardiac compression symptoms.

Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction.

Recent improvements in fetal therapies and perinatal care and the multidisciplinary involvement in fetal medicine have increased the demand for more accurate prenatal diagnosis. Fetal Magnetic Resonance Imaging (MRI) is a complementary imaging technique for the assessment of thoraco-abdominal anomalies for which Ultrasonography (US) is not conclusive. It is indicated in selected situations to precise the prognosis in diaphragmatic hernia, to characterise the nature and extension of a pulmonary malformation, to locate a bowel atresia or to better depict an abdominal cystic lesion or tumoural extension.

The diaphragm is the main breathing muscle and contraction of the diaphragm is vital for ventilation so any disease that interferes with diaphragmatic innervation, contractile muscle function, or mechanical coupling to the chest wall can cause diaphragm dysfunction. Diaphragm dysfunction is associated with dyspnoea, intolerance to exercise, sleep disturbances, hypersomnia, with a potential impact on survival. Diagnosis of diaphragm dysfunction is based on static and dynamic imaging tests (especially ultrasound) and pulmonary function and phrenic nerve stimulation tests. Read More

This article presents a multi-modality tracking and navigation system achieved by merging optical tracking and ultrasound imaging into a novel navigation software to help in surgical pre-planning and real-time target setting and guidance. Fetal surgeries require extensive experience in coordination of hand-eye-ultrasound-surgical equipment, knowledge, and precise assessment of relative anatomy. While there are navigation systems available for similar constrained working spaces in arthroscopic and cardiovascular procedures, fetal minimally invasive surgery does not yet have a dedicated navigation platform capable of supporting robotic instruments that can be adapted to the set of unique procedures.

Release of neurotransmitters from synaptic vesicles begins with a narrow fusion pore, the structure of which remains unresolved. To obtain a structural model of the fusion pore, we performed coarse-grained molecular dynamics simulations of fusion between a nanodisc and a planar bilayer bridged by four partially unzipped SNARE complexes. The simulations revealed that zipping of SNARE complexes pulls the polar C-terminal residues of the synaptobrevin 2 and syntaxin 1A transmembrane domains to form a hydrophilic core between the two distal leaflets, inducing fusion pore formation.
