Preservation of postural control of transient lower oesophageal sphincter relaxations in patients with reflux oesophagitis. (1/1553)

INTRODUCTION: In normal subjects, transient lower oesophageal sphincter relaxations (TLOSRs) and gas reflux during belching are suppressed in the supine position. Supine reflux, however, is a feature of reflux disease. AIMS: To investigate whether postural suppression of TLOSRs and gas reflux is impaired in patients with reflux disease. PATIENTS: Ten patients with erosive oesophagitis. METHODS: Oesophageal manometry was performed during gastric distension with 750 ml carbon dioxide. Measurements were made for 10 minutes before and after distension in both sitting and supine positions. RESULTS: In the sitting position gastric distension substantially increased the rate of gas reflux (median (interquartile range)), as evidenced by increases in oesophageal common cavities from 1 (0-1)/10 min to 7 (5-10)/10 min and TLOSRs from 1 (1-1.5)/10 min to 6 (2.5-8)/10 min. However, this effect was suppressed in the supine position in all but one patient (TLOSRs 0 (0)/10 min to 1 (0-4.5)/10 min, common cavities 0 (0)/10 min to 0.5 (0-2)/10 min). CONCLUSIONS: Postural suppression of TLOSRs and gas reflux is generally preserved in reflux disease.  (+info)

The effect of hiatus hernia on gastro-oesophageal junction pressure. (2/1553)

BACKGROUND: Hiatus hernia and lower oesophageal sphincter hypotension are often viewed as opposing hypotheses for gastro-oesophageal junction incompetence. AIMS: To examine the interaction between hiatus hernia and lower oesophageal sphincter hypotension. METHODS: In seven normal subjects and seven patients with hiatus hernia, the squamocolumnar junction and intragastric margin of the gastro-oesophageal junction were marked with endoscopically placed clips. Axial and radial characteristics of the gastro-oesophageal junction high pressure zone were mapped relative to the hiatus and clips during concurrent fluoroscopy and manometry. Responses to inspiration and abdominal compression were also analysed. RESULTS: In normal individuals the squamocolumnar junction was 0.5 cm below the hiatus and the gastro-oesophageal junction high pressure zone extended 1.1 cm distal to that. In those with hiatus hernia, the gastro-oesophageal junction high pressure zone had two discrete segments, one proximal to the squamocolumnar junction and one distal, attributable to the extrinsic compression within the hiatal canal. Inspiration and abdominal compression mainly augmented the distal one. Simulation of hernia reduction by algebraically summing the proximal segment pressures with the hiatal canal pressures restored normal maximal pressure, radial asymmetry, and dynamic responses of the gastro-oesophageal junction. CONCLUSIONS: Hiatus hernia reduces lower oesophageal sphincter pressure and alters its dynamic responsiveness by spatially separating pressure components derived from the intrinsic lower oesophageal sphincter and the extrinsic compression of the oesophagus within the hiatal canal.  (+info)

Erythromycin enhances early postoperative contractility of the denervated whole stomach as an esophageal substitute. (3/1553)

OBJECTIVE: To determine whether early postoperative administration of erythromycin accelerates the spontaneous motor recovery process after elevation of the denervated whole stomach up to the neck. SUMMARY BACKGROUND DATA: Spontaneous motor recovery after gastric denervation is a slow process that progressively takes place over years. METHODS: Erythromycin was administered as follows: continuous intravenous (i.v.) perfusion until postoperative day 10 in ten whole stomach (WS) patients at a dose of either 1 g (n = 5) or 2 g (n = 5) per day; oral intake at a dose of 1 g/day during 1.5 to 8 months after surgery in 11 WS patients, followed in 7 of them by discontinuation of the drug during 2 to 4 weeks. Gastric motility was assessed with intraluminal perfused catheters in these 21 patients, in 23 WS patients not receiving erythromycin, and in 11 healthy volunteers. A motility index was established by dividing the sum of the areas under the curves of >9 mmHg contractions by the time of recording. RESULTS: The motility index after IV or oral administration of erythromycin at and after surgery was significantly higher than that without erythromycin (i.v., 1 g: p = 0.0090; i.v., 2 g: p = 0.0090; oral, 1 g: p = 0.0017). It was similar to that in healthy volunteers (i.v., 1 g: p = 0.2818; oral, 1 g: p = 0.7179) and to that in WS patients with >3 years of follow-up who never received erythromycin (i.v., 1 g: p = 0.2206; oral, 1 g: p = 0.8326). The motility index after discontinuation of the drug was similar or superior to that recorded under medication in four patients who did not experience any modification of their alimentary comfort, whereas it dropped dramatically parallel to deterioration of the alimentary comfort in three patients. CONCLUSIONS: Early postoperative contractility of the denervated whole stomach pulled up to the neck under either i.v. or oral erythromycin is similar to that recovered spontaneously beyond 3 years of follow-up. In some patients, this booster effect persists after discontinuation of the drug.  (+info)

A manometric assessment of oesophagogastrostomy. (4/1553)

Intraluminal pressures were recorded in 14 patients who had undergone oesophagogastrectomy. Seven of these had a mid-thoracic and seven a high cervical oesophagogastrostomy. The incidence of postoperative reflux complications in each group was noted. No pressure gradient across the anastomosis was detected in any patient but the upper oesophageal sphincter was shown to be retained as a functioning unit in all cases. It is considered that the thoracic anastomosis provides no demonstrable barrier to reflux. In addition, a high cervical oesophagogastrostomy does not adversely affect the upper oesophageal sphincter. The wider application of this latter procedure may be associated with a decreased incidence of postoperative reflux complications.  (+info)

Effect of motilin on the lower oesophageal sphincter. (5/1553)

The effect of motilin on lower oesophageal sphincter (LES) pressure has been studied in unanesthetised specially trained dogs using an infusion manometric technique. Motilin produced significant rises in resting pressure and contractions of the LES after doses ranging from 0-009 mug/kg to 0-05 mug/kg. Doses greater than 0-05 mug/kg resulted in repetitive high amplitude contractions. Atropine 30 mug/kg completely abolished the effect of the lower doses of motilin. Higher doses of motilin in atropinised dogs still caused a small rise in baseline pressure and contractile activity still appeared. Hexamethonium 2 mg/kg resulted in both a diminished rise in LES pressure and the disappearance of contractions after motilin. Hexamethonium and atropine together completely abolished the LES response to motilin. We conclude that motilin increases LES pressure by acting on preganglionic cholinergic neurones to release acetylcholine which excites other cholinergic neurones supplying the circular muscle of the LES.  (+info)

Validation of a novel luminal flow velocimeter with video fluoroscopy and manometry in the human esophagus. (6/1553)

There is currently no ideal method for concurrently assessing intraluminal pressures and flows in humans with high temporal resolution. We have developed and assessed the performance of a novel fiber-optic laser-Doppler velocimeter, mounted in a multichannel manometric assembly. Velocimeter recordings were compared with concurrent fluoroscopy and manometry following 50 barium swallows in healthy subjects. During these swallows, the velocimeter sensor was situated in either the proximal (24 swallows) or the distal (26 swallows) esophagus. It signaled intraluminal flow following 46 of 50 swallows. A greater mean number of deflections were recorded in the distal compared with the proximal esophagus (4. 3 vs. 2.4, P = 0.001). The maximal flow velocity recorded did not differ between the proximal and distal esophagus (76.7 vs. 73.8 mm/s). No velocimeter signals commenced after fluoroscopic lumen occlusion. The velocimeter signals were closely temporally related to fluoroscopic barium flow. Upward catheter movement on swallowing sometimes appeared to cause a velocimeter signal. Manometrically "normal" swallows were no different from "abnormal" swallows in the number and velocity of deflections recorded by the velocimeter. This novel instrument measures intraluminal flow velocity and pressures concurrently, thus enabling direct study of pressure-flow relationships. Flow patterns differed between the proximal and distal esophagus.  (+info)

Cholinergic blockade inhibits gastro-oesophageal reflux and transient lower oesophageal sphincter relaxation through a central mechanism. (7/1553)

BACKGROUND: Atropine, an anticholinergic agent with central and peripheral actions, reduces gastro-oesophageal reflux (GOR) in normal subjects and patients with gastro-oesophageal reflux disease (GORD) by inhibiting the frequency of transient lower oesophageal sphincter relaxation (TLOSR). AIMS: To compare the effect of methscopolamine bromide (MSB), a peripherally acting anticholinergic agent, with atropine on the rate and mechanism of GOR in patients with GORD. METHODS: Oesophageal motility and pH were recorded for 120 minutes in 10 patients with GORD who were studied on three separate occasions. For the first two recording periods, either atropine (15 microg/kg bolus, 4 microg/kg/h infusion) or saline were infused intravenously. MSB (5 mg orally, four times daily) was given for three days prior to the third recording period. RESULTS: Atropine significantly reduced basal LOS pressure (12.6 (0.17) mm Hg to 7.9 (0.17) mm Hg), and the number of TLOSR (8.1 (0.56) to 2.8 (0. 55)) and reflux episodes (7.0 (0.63) to 2.0 (0.43)) (p<0.005 for all comparisons). MSB reduced basal LOS pressure (12.6 (0.17) to 8.7 (0. 15) mm Hg, p<0.005), but had no effect on the frequency of TLOSR (8. 1 (0.56) to 7.5 (0.59)) and reflux episodes (7.0 (0.63) to 4.9 (0. 60)) (p>0.05). CONCLUSION: In contrast to atropine, MSB has no effect on the rate of TLOSR or GOR in patients with GORD. Atropine induced inhibition of TLOSR and GOR is most likely mediated through a central cholinergic blockade.  (+info)

Perception of and adaptation to rectal isobaric distension in patients with faecal incontinence. (8/1553)

BACKGROUND: Perception of, and adaptation of the rectum to, distension probably play an important role in the maintenance of continence, but perception studies in faecal incontinence provide controversial conclusions possibly related to methodological biases. In order to better understand perception disorders, the aim of this study was to analyse anorectal adaptation to rectal isobaric distension in subjects with incontinence. PATIENTS/METHODS: Between June 95 and December 97, 97 consecutive patients (nine men and 88 women, mean (SEM) age 55 (1) years) suffering from incontinence were evaluated and compared with 15 healthy volunteers (four men and 11 women, mean age 48 (3) years). The patients were classified into three groups according to their perception status to rectal isobaric distensions (impaired, 22; normal, 61; enhanced, 14). Anal and rectal adaptations to increasing rectal pressure were analysed using a model of rectal isobaric distension. RESULTS: The four groups did not differ with respect to age, parity, or sex ratio. Magnitude of incontinence, prevalence of pelvic disorders, and sphincter defects were similar in the incontinent groups. When compared with healthy controls, anal pressure and rectal adaptation to distension were decreased in incontinent patients. When compared with incontinent patients with normal perception, patients with enhanced perception experienced similar rectal adaptation but had reduced anal pressure. In contrast, patients with impaired perception showed considerably decreased rectal adaptation but had similar anal pressure. CONCLUSION: Abnormal sensations during rectal distension are observed in one third of subjects suffering from incontinence. These abnormalities may reflect hyperreactivity or neuropathological damage of the rectal wall.  (+info)

The esophagus is the tube that conducts food from your mouth to stomach. Food propulsion is accomplished by muscles in the wall of the esophagus squeezing in a coordinated fashion. In some people, the muscles do not function properly, or may squeeze too hard. Patients often complain of difficulty swallowing. Manometry is a method by which muscle contraction can be measured. Esophageal manometry allows the muscles of the esophagus to be examined for coordination of contractions and pressure of squeeze.. The second important feature of esophageal manometry involves the connection between the esophagus and stomach. A small ring of muscle at the connection site called the lower esophageal sphincter can be too tight or too loose, contributing to heartburn, pain and other symptoms. Esophageal manometry allows measurement of this muscular ring.. ...
Editor,-We read with interest the recent paper by Kahrilas et al on the effect of hiatus hernia on gastro-oesophageal junction pressure (Gut1999;44:476-482). These authors used a novel technique that combined vector manometry, fluoroscopy, and endoscopic tagging of anatomical landmarks to map the differences in pressure profile between patients with and without hiatus hernia. Analysis of the vector profiles, taken at end expiration, revealed two distinct high pressure zones in each of the seven patients with hiatus hernia. These were thought to represent an axial separation of the internal and external components of the lower oesophageal sphincter (LOS). When these high pressure zones were repositioned to represent a simulated reduction of the hernia, the vector profile took on the appearance of a normal sphincter. This study drew some interesting conclusions regarding the effect of hiatal herniation on LOS pressure dynamics. We would like to raise two issues with the authors-the method of ...

BACKGROUND: With the advent of high-resolution manometry (HRM), a new diagnosis, jackhammer esophagus, was introduced. Little is known about this rare condition, and the relationship between symptoms and hypercontractility is not always straightforward. The aim of our study was to describe a large cohort of patients with jackhammer esophagus and to investigate whether manometric findings are associated with the presence of symptoms. METHODS: All patients from 06, 2014 until 12, 2015 seen at two tertiary centers with at least one hypercontractile swallow (distal contractile integral [DCI] ,8000 mm Hg/s/cm) on HRM were analyzed ...
What to expect before, during and after your child has antro-duodenal manometry at Cincinnati Children's Hospital Medical Center.
Statistical analysis was performed using SPSS (version 13.0 for Windows, Chicago, IL, USA). Data were expressed as the mean±standard deviation (SD). One-way analysis of variance (ANOVA) was used to assess statistical significance for age, body mass index (BMI), and esophageal manometry parameters according to HH, CLE, ZAP, and GEFV status. Age, BMI, and esophageal manometry parameters were compared among patients with or without HH, CLE, and RE, and among groups with different ZAP and GEFV grades, using unpaired t-tests. Differences in HH, CLE, and RE according to ZAP and GEFV grades and the relationship between ZAP and GEFV grades were assessed using the chi-square test for trend. Spearmans rank correlation coefficient was calculated to examine the correlation between GEFV and RE grades, ZAP and RE grades, and HH and RE grades. To evaluate the ability of the variables of interest to predict CLE and RE, a logistic regression analysis model was used. The LESP and DEA values were compared using ...
Esophageal manometric systems with water-filled catheters have been characterized by the use of model experiments. The examined parameters have been: catheter dimension, catheter compliance, catheter resistance, pump type, pump compliance, and perfusion flow. Accurate static pressure measurements have been obtained for perfused systems independently of the investigated parameters. The dynamic characteristics vary with catheter diameter and perfusion flow. For catheters with low diameter, a narrow bandwidth is obtained for the investigated perfusion flows. The results have been expressed in terms of an electric model of the measurement system. Perfusion pumps with low compliance are recommended to improve the dynamic properties of the measurement system.. ...
Nineteen new locations have been designated as Rent Pressure Zones from today, following reforms to the Residential Tenancies Act.
Highpressure systems are usually called Fair Weather Systems because the 7 types of weather in a highpressure zone are generally comfortable and clear. Keep in mind that high and low pressures mean the air is under higher or lower pressure relative to the surrounding air. A highpressure zone can have a reading of 960 millibars (). And a lowpressure zone can have a reading of 980 ... ...

Mental stress ischemia (MSI) is associated with poor prognosis for coronary artery disease (CAD) and is amenable to treatment, yet no easily administered test exists to diagnose it. Given the known increase in systemic vascular tone in response to stress, we studied the ability of peripheral arterial tonometry (PAT), a noninvasive functional measure of arterial tone, to predict those vulnerable to MSI. Seventy-seven patients with chronic stable CAD were subjected to mental stress with concomitant assessment of myocardial perfusion and pulse wave amplitude. Nuclear perfusion imaging was used to document MSI, and PAT was used to measure pulse wave and microarterial tone. A ratio of PAT measurements during stress to those before stress was used to characterize vascular responses. Serum catecholamines and endothelin-1 (ET-1) were simultaneously measured. Subjects who experienced MSI had a lower average PAT ratio than those who did not (0.76 ¡À 0.04 vs. 0.91 ¡À 0.05, P = 0.03). A receiver ...
Anal manometry is another test that is recommended. This is a small device like a thermometer with a balloon attached to the end. The device is inserted into the rectum and the balloon is inflated. This is usually not painful or uncomfortable. A machine is attached to the device. This machine reads the pressure readings taken from the balloon. Manometry is performed to assess the strength of the sphincter muscles, rectal muscles and the nerve functions of the rectum. In addition, the balloon may be inflated to different sizes to determine when the rectum feels full. If the balloon is relatively large and still no sensation of fullness appears there may be a problem with the rectal nerve complexes.. ...
Distinct contraction waves (CWs) exist above and below the transition zone (TZ) between the striated and smooth muscle oesophagus. We hypothesize that bolus transport is impaired in patients with abnormal spatio-temporal coordination and/or contractile pressure in the TZ. Concurrent high resolution manometry and digital fluoroscopy were performed in healthy subjects and patients with reflux oesophagitis; a condition associated with ineffective oesophageal contractility and clearance. A detailed analysis of space-time variations in bolus movement, intra-bolus and intra-luminal pressure was performed on 17 normal studies and nine studies in oesophagitis patients with impaired bolus transit using an interactive computer based system. Compared with normal controls, oesophagitis patients had greater spatial separation between the upper and lower CW tails [median 5.2 cm (range 4.4-5.6) vs 3.1 cm (2.2-3.7)], the average relative pressure within the TZ region (TZ strength) was lower [30.8 mmHg ...
GERD affects as many as 40% of Americans. Millions of pts could potentially be treated with PPI therapy expectantly without a definitive diagnosis. This study looked at actual cost in an integrated healthcare system to determine when GERD testing might become cost effective when pts are placed on high dose PPI therapy. The primary care network oversees 120K pts with as many as 50K have electronic medical record (EMR) data and integrated pharmacy data. 2331 were taking PPIs. 224 were taking at least double dose PPI therapy. Integrated payor data showed the actual cost to the payor side of the system for PPIs. Payor data was available for the actual cost of esophageal manometry, 48hr Bravo, upper endoscopy (EGD). From these data and historical data indicating incidence of negative workups (no GERD=stop PPIs) the breakeven point for GERD testing was calculated. Accounting for the time value of the money invested in early GERD testing, a negative evaluation rate of 31% (1), and the average cost ...

I had my gallbladder taken out in October of 2003. I regret the decision to this day....I was better for about 8 months and am now so nauseated everyday Im truly losing the will to live. Ive been to 2 major medical centers in Chicago and all the doctors just think Im making it up. I burp about 100-200 times a day and I dont even drink pop or anything other than tea and water. I have had just about every test in the world done (13 Barium CT scans, Ultrasounds, Gastric emptying, esophageal manometry, upper gi xrays, lower gi xrays). I have started acupuncture for this and it helps somewhat, but I cant bear the thought of going through the rest of my life feeling like I should carry a trash can with me everywhere I go. If anyone has any suggestions PLEASE let me know. My GI doctor basically told me a couple weeks ago that I have gone through every antinausea/gerd medication out there and there is nothing else he can do. Please help ...

N2 - Background Endothelial dysfunction is a key step in the initiation and progression of atherosclerosis and subsequent cardiovascular complications. We examined whether peripheral endothelial function, as assessed by fingertip reactive hyperemia-peripheral arterial tonometry (RH-PAT), can provide additional clinical value to traditional risk factors for cardiovascular diseases in predicting coronary artery disease (CAD). Methods We included 118 stable patients who were ...
Introduction: Drug-eluting stents (DESs) are replacing bare-metal stents (BMSs), but in-stent restenosis (ISR) remains a problem. Impaired endothelial function is a key event in the atherosclerosis process and a predictor of future cardiovascular events. Reactive hyperemia index (RHI) assessed by peripheral arterial tonometry (PAT) evaluates endothelial function noninvasively.. Hypothesis: We prospectively assessed the prognostic value of RHI in predicting ISR after percutaneous coronary intervention (PCI).. Methods: RHI was measured using Endo-PAT 2000 before PCI (initial RHI) and at follow-up angiography (F/U RHI) in 249 consecutive patients who had successful PCI. F/U angiography was performed at six and nine months after PCI with BMS and DES, respectively. ISR was defined as percent diameter stenosis ,50% at F/U angiography assessed by quantitative coronary angiography.. Results: At F/U, ISR was seen in 68 patients (27.3%). F/U ln(RHI) was significantly lower in patients with ISR than in ...
To determine if cholangiography has an effect on sphincter of Oddi (SO) activity, a prospective study was conducted. Twenty-five patients with suspected SO dysfunction underwent biliary SO manometry (SOM). According to the modified Geenen-Hogan criteria, 12 were classified as biliary type III, seven were biliary type II, and six had idiopathic pancreatitis. Patients were sedated with i.v. medications acknowledged as not affecting biliary basal sphincter pressures, including diazepam, droperidol, and meperidine. Conventional station pull-through manometry of the biliary part of the sphincter was performed before and after contrast injections of the biliary system. In this study group, the mean basal sphincter pressure was not significantly altered by contrast injection (52.9 ± 42.1 mm Hg before vs 55.1 ± 38.1 mm Hg after, p = 0.52). In addition, there was concordance (normal vs abnormal) between basal sphincter pressure before and basal sphincter pressure after contrast injection in 24 of ...
The standard transmastoid facial recess approach has become the popular technique for cochlear implantation. Although this approach has been used for implantation in patients with common cavity malformations, in patients with this anomaly and severe abnormalities of the middle ear, this approach may be technically difficult and makes the facial nerve vulnerable to injury. Using a direct approach to the common cavity through the mastoid cavity, we have successfully performed cochlear implantation in 1 patient with a common cavity malformation. This transmastoid labyrinthotomy approach to the common cavity is an effective and simple technique for placing the electrode array. It minimizes the risk to the facial nerve and may decrease postoperative cerebrospinal fluid leaks.. ...
Eligible patients will present chest pain and/or dysphagia related to the following hypercontractile esophageal motility disorders: distal esophageal spasm, jackhammer esophagus, nutcracker esophagus or type III achalasia with normalization of the integrated relaxation pressure after treatment, based on the Chicago classification of esophageal motility disorders for high resolution manometry (HRM). Upper gastrointestinal endoscopy and barium swallow will be performed before BTX injection to eliminate secondary disorders.. This is a prospective, randomized, double blind, controlled trial comparing BTX injection to sham procedure (absence of injection, the clinical team performing the follow-up will not be aware of the result of the randomization).. Drugs which could affect esophageal motility (nitrates and calcium channel blockers) will be stopped during the study.. Included patients will undergo esophageal endoscopic ultrasound examination (EEUS) and upper gastrointestinal endoscopy under ...
TY - JOUR. T1 - Ambulatory 24-hour double-probe ph monitoring; the importance of manometry. AU - Johnson, Paul E.. AU - Koufman, James A.. AU - Nowak, Lisa J.. AU - Belafsky, Peter C.. AU - Postma, Gregory N.. PY - 2001/11. Y1 - 2001/11. N2 - Objective Historically, manometry has been used for sphincter localization before ambulatory 24-hour double-probe pH monitoring to ensure accurate placement of the probes. Recently, direct-vision placement (DVP), using transnasal fiberoptic laryngoscopy (TFL), has been offered as an alternative technique. Presumably, DVP might be used to precisely place the proximal (pharyngeal) pH probe; however, using DVP, there appears to be no way to accurately position the distal (esophageal) probe. The purpose of this study was to evaluate the accuracy of DVP for pH probe placement using manometric measurement as the gold standard. Methods Thirty patients undergoing pH monitoring participated in this prospective study. Each subject underwent manometric examination of ...
The esophagus is lined by both circular and longitudinal muscles that terminate at a 2- to 4-cm circular muscle layer called the LES. The LES accounts for approximately 90% of the basal pressure at the gastroesophageal junction, and functions as an anti-reflux barrier. Esophageal peristalsis is a very synchronized action regulated by the vagus nerve that both stimulates and inhibits neurons in the esophageal myenteric plexus. The disruption of coordination between excitatory and inhibitory signals to myenteric neurons results in esophageal motility.. Hypomotility of the esophageal body ranges from low wave amplitude to complete peristaltic failure, and etiologies include rheumatologic (scleroderma, connective tissue disorders), endocrinologic (diabetes mellitus, hypothyroidism) and other diseases (alcoholism, amyloidosis).. The shared symptom of these disorders of hypomotility is gastroesophageal reflux disease (GERD). Food impaction and slow transit of pills may result in caustic esophageal ...
Jonas S Jensen, MD, Jan M Krzak, MD, Lars Stig Jorgensen, MD. Lillebaelt Hospital, Kolding, Denmark. Introduction: Examination of dysphagia in Danish surgical departments, rely primarily on upper gastrointestinal endoscopy. When no visible or histological cause can be detected, esophageal motility disorders are important differential diagnosis. In examining these disorders and in evaluating gastroesophageal reflux disorder (GERD), High Resolution Esophageal Manometry (HRM), provide valuable insights.. The purpose of this study was to examine referrals and final diagnosis from HRM in a surgical center specializing in esophageal disorders.. Methods and Procedures: All patients referred to HRM at our surgical center were included in the study and HRM was performed from September 2013 to June 2015. All patients had previously undergone upper gastrointestinal endoscopy at our center or the referring department. All procedures were performed using InSIGHT™ HRiM® and accompanying software (Sandhill ...
Methods 116 consecutive patients clinically diagnosed with AMI received evaluation of vascular endothelial function using PAT technique within 72 h of admission, reactive hyperaemia index (RHI) was calculated. By the cut point of normal RHI (1.67) patients were divided into the normal endothelial function group (RHI ,=1.67) and the endothelial dysfunction group (RHI,1.67), follow-up of MACE was conducted in both groups during hospitalisation (median value 8.0 days) and after discharge from hospital (243.8±68.3 days). MACE included cardiac death, recurrent acute myocardial infarction, recurrent unstable angina during hospitalisation, ischaemic stroke, elective PCI or CABG, and hospitalisation due to cardiovascular causes.. ...

Well, Jake had his Manometry test done at Childrens Floating on Tuesday, and with this test being the end of the road to find out why Jake is having these problems...we were VERY happy to FINALLY get some answers... Yes, that is right, They were able to find out what is wrong with our little man. Jake has some called Neuropathy, this is a widely used term for Nerve damage. His falls in the catagory if Autonomic Nerve damage, which effects the GI system. Which is why he is has the chronic vomit and diarrhea. At this point we do not have all the details of how serve the nerve damage is. The DR still needs to look at the tracings from the test and measure things. Unfortunately since he had this test after the fundoplication, we will not know if he had this problem prior to the fundoplication or not. Although we do know that by having the fundoplication, there is a good chance a nerve called the Vagus nerve was damaged during the operation, ( this is a long nerve that runs from the brain stem all ...
Lipoprotein phospholipase A2 (Lp-PLA2) is an emerging inflammatory marker with prognostic value. Reactive hyperemia peripheral arterial tonometry (RH-PAT) is a method to assess peripheral microvascular endothelial function and is linked to coronary microvascular endothelial dysfunction. We investigated the association of Lp-PLA2 with RH-PAT, coronary flow reserve (CFR), and carotid intimal media thickness in CAD patients. Methods: Using RH-PAT, digital pulse volume changes during reactive hyperemia were assessed in 43 patients with angiographically documented CAD. RH-PAT index, a measure of reactive hyperemia, was calculated as the ratio of the digital pulse volume during reactive hyperemia divided by that at baseline using the Endo-PAT apparatus. Coronary flow reserve (CFR) of the LAD after adenosine infusion was assessed using Doppler echocardiography.The mean intima-media thickness (IMT) in common carotids and carotid bulbs using ultrasound imaging was also measured According to the values of ...
PFT and HRCT scan parameters were compared between patients with severe esophageal motor dysfunction (aperistalsis and decreased low esophageal sphincter pressure), patients with moderate dysfunction (hypoperistalsis), and patients without dysfunction on manometry.. During the initial evaluation, patients with severe esophageal motor impairment exhibited significantly decreased median values of diffusing capacity for carbon monoxide (DLCO), at 68%. This was compared to those with moderate and without esophageal dysmotility (94% and 104%, respectively). They also exhibited a higher prevalence of evidence for ILD on HRCT scan (57%, 27%, and 18%, respectively). At 2 years follow-up, patients with severe esophageal motor disturbances, compared with those without, had faster deterioration of DLCO median values (-16% vs +1%). In addition, they had higher frequency of ILD on HRCT scan (70% vs 25%).. Author Isabelle Marie, of the Centre Hospitalier Universitaire de Rouen-Boisguillaume, said on behalf of ...
Background: Cerebrospinal fluid (CSF) pressure measurement is routinely performed via a conventional water column manometer. There is increasing interest in using a digital manometer in measuring CSF pressures. The aim of this study is to compare column and digital manometers, in addition to measuring time to acquire the pressure readings. Research design and methods: This prospective study included 27 patients who were referred for a fluoroscopically guided lumbar puncture. Opening pressure and closing pressure measurements were done with a digital manometer and then a traditional water column manometer. The time to obtain each pressure measurement was also recorded and compared. Results: Mean time to obtain pressure reading was significantly lower in the digital manometer group when compared to the water column manometer group (8.1 seconds vs. 42.2 seconds, P|0.05 for opening pressure and 8.92 seconds vs. 45.15 seconds, P|0.05 for closing pressure). Correlation between the opening pressure

Subjects will be exposed to short term hypoxia aiming for a target saturation of 80% while haemodynamic and ventilatory parameters are measured. They will breathe through a mouthpiece connected to special equipment which delivers different gas mixtures and enables the delivery of the hypoxic exposure. Heart rate, blood pressure, arterial stiffness ( via pulse wave analysis), and peripheral vasoconstriction (via peripheral arterial tonometry PAT) will be measured. Initially there will be a 10 minute baseline period followed by the 20 minute period of hypoxia and then a 10 minute recovery period. A proportion of subjects will then be studied after being commenced on treatment with continuous positive airway pressure (CPAP). ...
We also tested whether spices and herbs could reduce postprandial lipid oxidation and endothelial dysfunction in individuals with type 2 diabetes, a very common condition known to lead to endothelial dysfunction. Postprandial lipid oxidation refers to the susceptibility of lipids or fats to oxidation after eating a meal; it is an important area of research because humans eat throughout the day and seldom fast for long periods. Postprandial oxidation is associated with metabolic disturbances that contribute to inflammation and endothelial dysfunction.. Eighteen men with type 2 diabetes completed the protocol. They were assigned to eat in a random order a cooked hamburger seasoned with salt and a spice mix or a hamburger seasoned only with salt. The spice mix was the same as the one described previously. Urinary MDA excretion, urinary nitric oxide species (NOx) excretion, and peripheral arterial tonometry (PAT) were measured. (Nitric oxide plays a major role in maintaining vascular tone; increased ...
The theory? That her esophagus is deteriorating further and shes aspirating. That shes able to clear her lungs with with a cough, but shes keeping gunk at the level of her trachea. The ped wants us to go back to the GI, who has some tests he wants us to do, along with that 3D CT that nobody realized he ordered 18 months ago! Apparently there was a consultation with the cardiologist who suggested doing this scan to see if her heart could be compressing her esophagus. Once thats done, well be down at Mayo to talk to the specialists there who deal with Achalasia. Weve talked to them in the past, but the ped. thinks its time to do some real serious looking right now. Also, she said the testing that was done 18 months ago will probably all need to be re-done (sleep study w/ph probe, esophageal manometry, and another endoscopy. Well probably throw in a bronch at the same time as the endoscopy as well.) The fix for achalasia isnt a pretty one, so Im praying thats not the direction were ...

Esophageal manometry is a diagnostic test of the nerves and muscles in the esophagus (feeding pipe). The test uses a thin flexible plastic catheter (tube) inserted through the nostril, into the esophagus, and ending in the stomach. Sensors on the catheter measure how the muscles of the esophagus squeeze and relax, and the information is recorded to a computer.

The wireless motility-recording capsule, SmartPill, is an ingested one-time use electronic capsule that measures gastrointestinal luminal pressure, pH and temperature along the whole gastrointestinal tract. The pH profile and the pressure patterns define the time at which the capsule moves from the stomach to the duodenum and from the ileum to the caecum, whereas changes in temperature define the times of ingestion and expulsion. The recordings from the wireless motility capsule are sent from a radio transmitter in the capsule to a receiver carried around the waist. Wireless motility recordings have several advantages over imaging and manometry that have been used previously. Primarily the simplicity by which motility recordings are done, as well as the tolerability for the patient and limited need of assistance are valuable aspects. The wireless motility capsule provides standardized measures of transit with relevant normal values for the clinical work-up of patients with motility ...
So the Echo looked about the same so far the heart muscle itself isnt showing signs of hypertrophy (weakening. thickening) but my Cardiologist knows the L sided filling pressures are very abnormally high and thus creating severe L atrial enlargement. This could be the cause of the chest pain and shortness of breath and skipped beats/arrythmias but the aortic stenosis and very abnormal aortic and mitral valves as a whole with leaking and stenosis also factor in. He is ordering a cardiac perfusion test which they inject dye in and watch how this goes through the heart and muscle of the heart as the person exercises and this will tell him if the symptoms are from not enough blood and oxygen is getting to any part of the heart. The test will also tell us if there is diffuse coronary narrowing which he said is very different than CAD in a non-MPS person and in the literature has rarely been reported to cause symptoms but he still wants to make sure it isnt the cause/addition to our issues.
