Case report of eventration of diaphragm due to an unknown febrile illness causing phrenic nerve palsy and other multiple nerve palsies.

ABSTRACT: Introduction:Diaphragmatic eventration can be congenital or acquired. Diagnosis is delayed due to no symptoms or very mild ones and is generally done by imaging modalities. This condition is managed by plication of the affected part of diaphragm by various surgical approaches. Presentation of case:A forty seven years lady presented with one year long history of abdominal pain, bloating and fullness after meals who was being treated in line of peptic acid disorder. She had developed bilateral foot drop after typhoid fever at seventeen years of age. Clinical examination and imaging with chest x-ray, chest ultrasound and computed tomography scan suggested eventration of left hemidiaphragm. Plication of eventration of left hemidiaphragm was done via mini thoracotomy of the left thorax. There were no postoperative complications and she was discharged on the sixth postoperative day. Discussion:Acquired eventration of diaphragm is commonly due to traumatic phrenic nerve palsy but rarely can be associated with a history of infection causing nerve palsies. Thoracic ultrasound is an emerging modality for diagnosis supporting X-rays and CT Scans. Plication of eventration with minimally invasive techniques has less number of hospital stay and less pain compared to open approaches. Conclusion:Non-traumatic diaphragmatic eventration due to acquired phrenic nerve palsy following an unknown febrile illness is a rare case to be reported in Nepal. The aim of treatment is expansion of intra-thoracic space which is done by plication of the diaphragm.

Project description:Recent studies have shown that brief periods of mechanical ventilation in animals and humans can lead to ventilator-induced diaphragmatic dysfunction, which includes muscle atrophy, reduced force development, and impaired mitochondrial function. Studies in animal models have shown that short periods of increased diaphragm activity during mechanical ventilation support can attenuate ventilator-induced diaphragmatic dysfunction but corresponding human data are lacking. The purpose of this study was to examine the effect of intermittent diaphragm contractions during cardiothoracic surgery, including controlled mechanical ventilation, on mitochondrial respiration in the human diaphragm.Within subjects repeated measures study.Operating room in an academic health center.Five subjects undergoing elective cardiothoracic surgery.In patients (age 65.6 ± 6.3 yr) undergoing cardiothoracic surgery, one phrenic nerve was stimulated hourly (30 pulses/min, 1.5 msec duration, 17.0 ± 4.4 mA) during the surgery. Subjects received 3.4 ± 0.6 stimulation bouts during surgery. Thirty minutes following the last stimulation bout, samples of diaphragm muscle were obtained from the anterolateral costal regions of the stimulated and inactive hemidiaphragms.Mitochondrial respiration was measured in permeabilized muscle fibers with high-resolution respirometry. State III mitochondrial respiration rates (pmol O2/s/mg wet weight) were 15.05 ± 3.92 and 11.42 ± 2.66 for the stimulated and unstimulated samples, respectively (p < 0.05). State IV mitochondrial respiration rates were 3.59 ± 1.25 and 2.11 ± 0.97 in the stimulated samples and controls samples, respectively (p < 0.05).These are the first data examining the effect of intermittent contractions on mitochondrial respiration rates in the human diaphragm following surgery/mechanical ventilation. Our results indicate that very brief periods (duty cycle ~1.7%) of activity can improve mitochondrial function in the human diaphragm following surgery/mechanical ventilation.
