OBJECTIVE To investigate the applicability of ultrasound imaging of the diaphragm in interstitial lung disease (ILD). METHODS Using ultrasound, we compared ILD patients and healthy volunteers (controls) in terms of diaphragmatic mobility during quiet and deep breathing; diaphragm thickness at functional residual capacity (FRC) and at total lung capacity (TLC); and the thickening fraction (TF,...

Background: Diaphragmatic excursion during spontaneous ventilation (SV) in normal supine volunteers is greatest in the dependent regions (bottom). During positive pressure ventilation (PPV) after anesthesia and neuromuscular blockade and depending on tidal volume, the nondependent region (top) undergoes the greatest excursion, or the diaphragm moves uniformly. The purpose of this study was to c...

CONTEXT Mandibular movements (MM) are considered as reliable reporters of respiratory effort (RE) during sleep and sleep disordered breathing (SDB), but MM accuracy has never been validated against the gold standard diaphragmatic electromyography (EMG-d). OBJECTIVES To assess the degree of agreement between MM and EMG-d signals during different sleep stages and abnormal respiratory events. ...

Thoracobiliary fistula is a rare complication of hydatid cyst of the liver especially in the calcified form. Surgery is the only medical option. The treatment consists of radical surgical procedures in the majority of the patients. Conservative surgical treatments are performed with high mortality rate. Herein, we will describe two patients of calcified hydatid cysts of the liver whose conditio...

introduction: diaphragmatic hernia could be caused by congenital disorders, blunt trauma or penetrating injuries. the diagnosis of traumatic diaphragmatic hernia is normally neglected during the first presentation leading to late complications and considerably increased mortality and morbidity among the patients. materials and methods: in this retrospective, descriptive study, we reviewed the m...

Respiratory muscle-associated stretch has been implicated in normal lung development (fetal breathing movements) and postpneumonectomy lung growth. To test the hypothesis that mechanical stretch from diaphragmatic contraction contributes to lung growth, we performed left phrenic nerve transections (PNT) in mice with and without ipsilateral pneumonectomy. PNT was demonstrated by asymmetric costa...

Thoracoabdominal breathing movements are a complex source of postural disturbance, but there are contradictory reports in the literature with inspiration described as having either a backward or a forward disturbing effect. To elucidate the mechanisms underlying this phenomenon, the present study studied the postural disturbance caused by isolated contractions of the diaphragm. Eight male and f...

BACKGROUND Pleural effusion adversely affects the pressuregenerating capacity of the diaphragm. It uncouples the lung and chest wall, which may result in diaphragmatic dysfunction. Information on the effects of effusion drainage on diaphragmatic function is limited, but several studies report relief of dyspnoea after drainage, which was attributed to improved diaphragmatic mechanics, even if th...

OBJECTIVES Compare the surgical morbidity of diaphragmatic peritonectomy versus full thickness diaphragmatic resection with pleurectomy at radical debulking. DESIGN Prospective cohort study at the Oxford University Hospital. METHODS All debulking with diaphragmatic peritonectomy and/or full thickness resection with pleurectomy in the period from April 2009 to March 2012 were part of the stu...

OBJECTIVE To evaluate diaphragmatic motion via M-mode ultrasonography and to correlate it with pulmonary function in stroke patients. METHODS This was a preliminary study comprised of ten stroke patients and sixteen healthy volunteers. The M-mode ultrasonographic probe was positioned in the subcostal anterior region of the abdomen for transverse scanning of the diaphragm during quiet breathin...
