A rare adverse event of a right-sided pneumectomy with an elevated hemidiaphragm is right-to-left shunting through a patent foramen ovale. In this case report we describe our experience with plication of the right hemidiaphragm with instantaneous hemodynamic results and pain relief, followed by secondary closure of the foramen ovale.

OBJECTIVES: To assess whether horizontal versus vertical bolster orientation affects kidney position during prone percutaneous nephrolithotomy as this could impact the need for supracostal access and therefore the likelihood of pleural injury. METHODS: In a prospective trial, ten subjects with 20 renal units underwent magnetic resonance imaging in prone position with standard cylindrical bolsters oriented vertically and then horizontally. Vertical bolsters were placed along the lateral aspect of the chest...

REVIEW
Hamish Philpott, Rami Sweis
PURPOSE OF REVIEW: This review aims to discuss the putative relationship between hiatus hernia and dysphagia. RECENT FINDINGS: Proposed mechanisms of dysphagia in patients with hiatus hernia are usually difficult to identify, but recent advances in technology (high-resolution manometry with or without concomitant impedance, ambulatory pH with impedance, videofluoroscopy, and the endoluminal functional lumen imaging probe (EndoFLIP)) and methodology (inclusion of swallows of various consistencies and volumes or shifting position during the manometry protocol) can help induce symptoms and identify the underlying disorder...

Regulated intracellular proteostasis, controlled in part by proteolysis, is essential in maintaining the integrity of podocytes and the glomerular filtration barrier of the kidney. We applied a novel proteomics technology that enables proteome-wide identification, mapping, and quantification of protein N-termini to comprehensively characterize cleaved podocyte proteins in the glomerulus in vivo We found evidence that defined proteolytic cleavage results in various proteoforms of important podocyte proteins, including those of podocin, nephrin, neph1, α-actinin-4, and vimentin...

RATIONALE: Splenosis is the development of one or more heterotopic splenic tissue autoimplants following rupture of the spleen and remains mostly asymptomatic. PATIENT CONCERNS: We report a case of a 50-year old post-traumatic splenectomized man admitted for a left side community acquired pneumonia resistant to antibiotics. DIAGNOSES: The diagnosis of intrathoracic ectopic spleen was suspected because of the history of spleen trauma with diaphragm rupture and the absence of Howell-Jolly bodies...

INTRODUCTION: High-tension electricity can cause devastating injuries that may result in abdominal wall loss, visceral damage, and sometimes major threat to life. The visceral organ may be exposed after debridement and require flap cover, but the tensile strength of abdominal wall may be lack even if flap transplanted. METHODS: From April 2007 through May 2015, 5 patients with severe abdominal electrical injury were treated at our hospital. Exploratory laparotomy was performed based on their clinical manifestations and debridement findings of abdominal wall at early stage, and decision regarding technique for reconstruction of abdominal wall was based on an assessment of the location and extent of the defect...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

BACKGROUND/AIMS: Diabetic nephropathy (DN) is a microangiopathic disease characterized by excessive urinary albumin excretion, which occurs in 30% of patients with diabetes mellitus. It is the second leading cause of end-stage renal diseases in China. Nuclear factor-kappa B (NF-κB) is reported to be closely correlated with the inflammation underlying diabetes-associated renal damage. Crocin, a plant-derived compound, has antioxidant properties that may inhibit NF-κB. METHODS: In the present study, we used a conditionally immortalized mouse podocyte cell line to explore whether crocin could effectively block albuminuria...

Mammalian podocytes, the key determinants of the kidney's filtration barrier, differentiate from columnar epithelial cells and several key determinants of apical-basal polarity in the conventional epithelia have been shown to regulate podocyte morphogenesis and function. However, little is known about the role of Crumbs, a conserved polarity regulator in many epithelia, for slit-diaphragm formation and podocyte function. In this study, we used Drosophila nephrocytes as model system for mammalian podocytes and identified a conserved function of Crumbs proteins for cellular morphogenesis, nephrocyte diaphragm assembly/maintenance, and endocytosis...

Fibromuscular dysplasia (FMD) commonly affects the renal and cervical arteries but has been described to affect other vascular beds as well. The prevalence of and clinical characteristics associated with multisite FMD (string-of-beds or focal stenoses affecting at least 2 vascular beds) are not known. In the prospective ARCADIA registry (Assessment of Renal and Cervical Artery Dysplasia), symptomatic patients with renal artery (RA) FMD underwent tomographic- or magnetic resonance-angiography from the aortic arch to the intracranial arteries and those with cervical FMD from the diaphragm to the pelvis...

A passive surface acoustic wave (SAW) pressure sensor was developed for real-time pressure monitoring in downhole application. The passive pressure sensor consists of a SAW resonator, which is attached to a circular metal diaphragm used as a pressure transducer. While the membrane deflects as a function of pressure applied, the frequency response changes due to the variation of the SAW propagation parameters. The sensitivity and linearity of the SAW pressure sensor were measured to be 8.3 kHz/bar and 0.999, respectively...

BACKGROUND: In this single-center study, we sought to determine the frequency of phrenic nerve injury leading to diaphragm paresis (DP) in children following open cardiac surgery over the last 10 years, and to identify possible variables that predict the need for plication and associated clinical outcomes. METHODS: Patients diagnosed with DP were identified from departmental databases and a review of clinical diaphragm ultrasound images. A cohort was analyzed for predictors of diaphragm plication and associations with clinical outcomes...

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...

This study developed an in vitro diaphragm motion reproduction system (IVDMRS) based on noninvasive and real-time ultrasound imaging to track the internal displacement of the human diaphragm and diaphragm phantoms with a respiration simulation system (RSS). An ultrasound image tracking algorithm (UITA) was used to retrieve the displacement data of the tracking target and reproduce the diaphragm motion in real time using a red laser to irradiate the diaphragm phantom in vitro. This study also recorded the respiration patterns in 10 volunteers...

A 78-year-old man presented to the accident and emergency department with acute abdominal pain. A CT scan done to investigate the pain showed an intra-abdominal abscess medial to the caecum and an incidental exophytic lesion in the gall bladder. This was excised during surgery and sent for histological examination. Histology showed a ciliated foregut cyst of the gall bladder. A literature review revealed that this was the 13th case worldwide, as ciliated foregut cysts are usually found either above the diaphragm or in the liver...

Bronchogenic cysts are congenital lesions developing during early embryogenesis. The intradiaphragmatic location is extremely rare. We present a giant bronchogenic cyst arising from the left crus of diaphragm. Based on our literature review results, intradiaphragmatic bronchogenic cysts have the following characteristics: 1) they are more common in female patients; 2) the patients are usually asymptomatic, or present with symptoms of chest pain, abdominal pain, and hiccups; 3) the cysts located in the left diaphragm are more than those in the right diaphragm, most of which are located in the area of the left diaphragm crus...

Paul H Sugarbaker
Malignant pleural mesothelioma is a disease characterized by persistent and progressive disease within the hemithorax. However, after aggressive local-regional treatment using surgery, regional chemotherapy, radiation therapy, and systemic chemotherapy, metastases outside of the pleural space may become the chief obstacle to long-term survival. One possible direction of cancer dissemination is direct extension through the hemidiaphragm into the peritoneal space by the disease itself or as a result of diaphragm resection...

Congenital diaphragmatic hernia (CDH) usually presents in the neonatal period, and about 10% of reported cases occur in adults. The most common type is Bochdalek's hernia, which occurs through a defect in the posterolateral portion of the diaphragm with an estimated prevalence of 1 in 2500 live births. CDH in adults presents with gastrointestinal or respiratory symptoms, which can be acute or intermittent. We report a case of CDH diagnosed in a 55-year-old man, who presented with acute onset of chest pain and dyspnea with insignificant past history...
