OBJECTIVES: Diaphragmatic paralysis, a known cause of dyspnoea, can drastically reduce breathing efficiency, diminishing quality of life. We report our 3.5-year experience with 22 consecutive patients who underwent transabdominal, robot-assisted diaphragmatic plication for diaphragmatic paralysis. METHODS: We retrospectively reviewed 22 consecutive patients who underwent this procedure by a single surgeon from 5 September 2012 to 12 May 2016. The primary outcome measure was change in dyspnoea severity, which was measured with the 5-point Medical Research Council dyspnoea scale (a score of 5 indicates breathlessness so severe, the individual is homebound)...

Thirty patients aged 11 to 21 years presenting in an adolescent medicine clinic received a one-time stress management intervention. The intervention included psychoeducation on the effect stress has on the body and the positive benefits of exercise, diaphragmatic breathing, and progressive muscle relaxation. The intervention also included use of a biofeedback game to aid in relaxation. Analyses revealed an association between higher levels of internalizing symptoms and perceived stress. A clinically significant decrease in subjective distress was endorsed at post-intervention...

OBJECTIVES: First ribs bear information about thorax morphology and are usually well preserved, compared to other ribs, in bone/fossil samples. Several studies have addressed ontogeny of the first rib by studying changes in bone microanatomy and rib morphology separately, but no studies have combined both approaches to study how internal and external changes covary during ontogeny. The aim of this project is to fill this gap in our knowledge. MATERIALS AND METHODS: We applied 3D geometric morphometrics of sliding semilandmarks to 14 first ribs of Homo sapiens to quantify rib curvature and mid-shaft cross-section outline...

Although women experience greater ventilatory constraints and have a higher work of breathing during exercise, they are less susceptible to diaphragm fatigue compared to men. The mechanisms for diaphragmatic fatigue resistance in women is unknown but may be related to sex differences in respiratory muscle recruitment. Accordingly, the purpose of this study was to determine if electromyography (EMG) of the diaphragm (EMGdi) and extra-diaphragmatic inspiratory muscles differ between sexes during exercise. Forty subjects (21M:19F) completed a constant load cycling test at 85% of maximum work rate until exhaustion, while instrumented with an oesophageal electrode catheter to measure EMGdi and surface electrodes to measure EMG of the sternocleidomastoid (EMGscm) and scalene (EMGsca) muscles...

The present study was designed to investigate the diaphragm and intercostal muscle activity following unilateral mid-cervical spinal cord contusion in rats. Electromyogram (EMG) activity of the bilateral diaphragm and T2 intercostal muscle was measured in anesthetized and spontaneously breathing rats. Unilateral mid-cervical contusion caused an immediate reduction in inspiratory bursting in the bilateral diaphragm and intercostal muscles. From 3 days to 8 weeks post-contusion, the contused animals displayed significantly lower tidal volume than uninjured animals, regardless of the time point after injury...

Hernia of Morgagni is the most rare of the four types of congenital diaphragmatic hernia (2 % - 3 % of all cases). In adults, it commonly presents with non-specific symptoms. In severe cases patients complain about shortness of breath and in lung function analysis a restrictive pattern can be observed. This paper presents a rare case of a massive diaphragmatic hernia of the right thorax which remained undiagnosed over many years and gives an up-to-date overview of the literature. The transabdominal approach using laparoscopic repair is favored in adults especially in non-acute cases...

Kun-Ze Lee, Elisa J Gonzalez-Rothi
Unilateral C2 spinal cord hemisection (C2Hx) interrupts bulbospinal respiratory pathways innervating ipsilateral phrenic motoneurons, resulting in cessation of ipsilateral diaphragm motor output. Plasticity within the spinal neural circuitry controlling the diaphragm can induce partial recovery of phrenic bursting which correlates with the time-dependent return of spinal serotonin (5-HT) immunoreactivity in the vicinity of phrenic motoneurons. The 5-HT2A receptor subtype is present on phrenic motoneurons and its expression is up-regulated after cervical spinal cord injury; however the functional role of these receptors following injury has not been clearly defined...

INTRODUCTION: Spinal cord injuries in new born infants following a traumatic delivery or umbilical cord catheterisation due to thromboembolism are well known. Cases with atraumatic acute onset of neonatal paraplegia have also been described in preterm babies or babies born small for gestational age with a stormy postnatal course related to ischaemic aetiology. We describe a rare case of infarction of the spinal cord from a predominant haemorrhagic aetiology. CASE PRESENTATION: A term female baby, first child of unrelated parents, was born by normal vaginal delivery...

Slow diaphragmatic breathing is one of the therapeutic methods used in behavioral therapy for panic disorder. In practice, we have noticed that some of these patients could not perform diaphragmatic breathing and their percent vital capacity was initially reduced but could be recovered through breathing training. We conducted a comparative study with healthy controls to investigate the relationship between diaphragmatic breathing ability and percent vital capacity in patients with panic disorder. Our findings suggest that percent vital capacity in patients with impaired diaphragmatic breathing was significantly reduced compared with those with normal diaphragmatic breathing and that diaphragmatic breathing could be restored by breathing training...

A growing number of empirical studies have revealed that diaphragmatic breathing may trigger body relaxation responses and benefit both physical and mental health. However, the specific benefits of diaphragmatic breathing on mental health remain largely unknown. The present study aimed to investigate the effect of diaphragmatic breathing on cognition, affect, and cortisol responses to stress. Forty participants were randomly assigned to either a breathing intervention group (BIG) or a control group (CG). The BIG received intensive training for 20 sessions, implemented over 8 weeks, employing a real-time feedback device, and an average respiratory rate of 4 breaths/min, while the CG did not receive this treatment...

[Purpose] The purpose of this study was to examine effects of diaphragm breathing exercise applied on the basis overload principle on respiratory function. [Subjects and Methods] The subjects of this study were 35 normal adults. They were randomly assigned to two group; the maneuver-diaphragm exercise group and self-diaphragm exercise group. The respiratory function was evaluated using the CardioTouch 3000S (BIONET, Korea) as a pulmometry device. [Results] The maneuver-diaphragm exercise was more effective on functional vital capacity and forced expiratory volume at one second when compared to the self-diaphragm exercise...

OBJECTIVE: Our objective in this study was to extend diaphragmatic pacing therapy to include paraplegic patients with high cervical spinal cord injuries between C3 and C5. INTRODUCTION: Diaphragmatic pacing has been used in patients experiencing ventilator-dependent respiratory failure due to spinal cord injury as a means to reduce or eliminate the need for mechanical ventilation. However, this technique relies on intact phrenic nerve function. Recently, phrenic nerve reconstruction with intercostal nerve grafting has expanded the indications for diaphragmatic pacing...
