Primitive hydatid disease of diaphragm is very rare. The preoperative diagnosis of this hydatid location represents a challenge for the radiologist. We reported a case of primitive hydatid cyst of the diaphragm not associated with other hydatid localizations which was diagnosed preoperatively. A 70 year-old woman with no previous medical history, complained of abdominal pain in the right upper quadrant for 7 months. The physical exam and the laboratory tests were unremarkable. Abdominal ultrasound showed multiloculated cystic lesion which appeared to be located in the hepatic dome suggestive of hydatid cyst of the liver...

The diaphragm is an unique skeletal muscle separating the thoracic and abdominal cavities with a primary function of enabling respiration. When abnormal, whether by congenital or acquired means, the consequences for patients can be severe. Abnormalities that affect the diaphragm are often first detected on chest radiographs as an alteration in position or shape. Cross-sectional imaging studies, primarily computed tomography (CT) and occasionally magnetic resonance imaging (MRI), can depict structural defects, intrinsic and adjacent pathology in greater detail...

BACKGROUND AND AIMS: During laparoscopic surgery, a capnoperitoneum is created to optimize the operating space for surgeons. One effect of this is abdominal pressure which alters the physiological thoraco-abdominal configuration and pushes the diaphragm and lungs cranially. Since the lung image acquired by electrical impedance tomography (EIT) depends on the conditions within the thorax and abdomen, it is crucial to know the diaphragm position to determine the effect of diaphragm shift on EIT thorax image...

BACKGROUND: The extensive use of neuromuscular blocking agents (NMBAs) during surgical procedures still leads to potential residual paralyzing effects in the postoperative period. Indeed, neuromuscular monitoring in an intra-operative setting is strongly advocated. Acetylcholinesterase inhibitors can reverse muscle block, but their short half-life may lead to residual curarization in the ward, especially when intermediate or long-acting NMBAs have been administered. Sugammadex is the first selective reversal drug for steroidal NMBAs; it has been shown to give full and rapid recovery of muscle strength, thus minimizing the occurrence of residual curarization...

The diaphragm is the primary muscle of respiration, and its weakness can lead to respiratory failure. Diaphragmatic palsy can be caused by various causes. Injury to the phrenic nerve during thoracic surgeries is the most common cause for diaphragmatic palsy. Depending on the cause, the symptoms of diaphragmatic palsies vary from completely asymptomatic to disabling dyspnea requiring mechanical ventilation. On pulmonary function tests, there will be a decrease in the maximum respiratory muscle power. Spirometry shows reduced lung functions and a significant drop of lung function in supine position is typical of diaphragmatic palsy...

Background: Weaning failure is a crucial hindrance in critically ill patients. Rapid shallow breathing index (RSBI), a well-known weaning index, has some limitations in predicting weaning outcomes. A new weaning index using point-of-care ultrasound with diaphragmic thickening fraction (DTF) has potential benefits for improving weaning success. The aim of this study was to evaluate the efficacy of a combination of DTF and RSBI for predicting successful weaning compared to RSBI alone. Methods: This prospective study enrolled patients from the medical intensive care unit or ward who were using mechanical ventilation and readied for weaning...

Non-specific low back pain (NS-LBP) is known to cause respiratory dysfunction. In this study, we investigated alterations in breathing, respiratory strength and endurance, core stability, diaphragm mobility, and chest expansion among patients with NS-LBP and healthy individuals. The specific aim of the study was to correlate between respiratory function and other variables among NS-LBP patients. Thirty four patients with NS-LBP were matched with 34 healthy participants before undergoing total faulty breathing scale, spirometer, respiratory pressure meter, chest expansion, ultrasound, and pressure biofeedback measurements...

Respiratory muscle weakness frequently occurs in patients with neuromuscular disease. Measuring respiratory function with standard pulmonary function tests provides information about the contribution of all respiratory muscles, the lungs and airways. Imaging potentially enables the study of different respiratory muscles, including the diaphragm, separately. In this review, we provide an overview of imaging techniques used to study respiratory muscles in neuromuscular disease. We identified 26 studies which included a total of 573 patients with neuromuscular disease...

RATIONALE: Congenital diaphragmatic hernia (CDH) associated congenital anomalies are present in about 25%. Congenital short esophagus (CSE) is a relatively rare condition. Both CDH and congenital intrathoracic stomach caused by CSE can be diagnosed in utero. However, CSE can be easily misdiagnosed in utero. PATIENT CONCERNS: We present a case of left CDH with CSE in a female neonate who was diagnosed at 24 weeks gestational age by antenatal ultrasound. DIAGNOSES: The neonate with CDH and congenital intrathoracic stomach due to CSE was confirmed by operation...

Diaphragm ultrasound (DUS) has been used to identify diaphragm dysfunction. However, its correlations with respiratory strength and lung function are unclear, even in healthy patients. A total of 64 healthy patients (30 males) had lung function and inspiratory strength (maximal inspiratory pressure and sniff nasal inspiratory pressure) measured. Gastric and oesophageal pressures were measured in a subgroup (n = 40). DUS was characterized by mobility (quiet breathing [QB] and deep breathing [DB]) and thickness (at functional residual capacity [ThFRC] and total lung capacity [ThTLC])...

BACKGROUND: Inspiratory muscle weakness is associated with the development of exercise intolerance in patients with heart failure (HF). Ultrasound assessment of the diaphragm is used to evaluate respiratory muscle function, but its application in patients with HF remains undefined. We examined the relationship of diaphragm function as assessed by ultrasonography with inspiratory muscle strength and exercise tolerance in HF. METHODS AND RESULTS: Seventy-seven patients hospitalized with HF were enrolled...

BACKGROUND: Ultrasound is a convenient tool to evaluate cardiac and diaphragm function. The ratio (E/Ea) of mitral Doppler inflow velocity to annular tissue Doppler wave velocity by transthoracic echocardiography (TTE) and diaphragmatic excursion (DE) by diaphragm ultrasound have been confirmed in predicting extubation outcomes independently, however their different roles in the weaning process have not been determined until now. METHODS: We designed a cohort study to preform diaphragm ultrasound and TTE before and after the spontaneous breathing trial (SBT) in difficult-to-wean patients...
