Assessment of various factors influencing esophageal pressure measurement
1980
Die intraluminale Manometrie wird zunehmend fur die Diagnose osophagealer Motilitatsstorungen eingesetzt. Die klinische Validitat der Methode hangt jedoch entscheidend von einer exakten Standardisierung der Methodik, des Untersuchungsablaufes und der Kenntnis der Einflusgrosen auf das Mesergebnis ab. Im ersten Teil dieser Studie wurde der Einflus verschiedener methodischer Faktoren auf das Ergebnis der Osophagusdruckmessung in Modellversuchen, bei 44 gesunden Probanden und bei 74 Patienten mit axialer Hiatushernie mit einem elektromagnetischen Mikrotransducer untersucht. Signifikante Unterschiede der Meswerte fanden sich in Abhangigkeit von der Sensorposition im oberen Osophagussphinkter (p…
Laparoscopic treatment for esophageal achalasia: experience at a single center
2013
Background. Achalasia is a not frequent esophageal disorder cha- racterized by the absence of esophageal peristalsis and incomplete re- laxation of the lower esophageal sphincter (LES). Its cause is unknown. The aim of treatment is to improve the symptoms. We report the results of the treatment of this condition achieved in one center. Patients and methods. We conducted a retrospective study of pa- tients with esophageal achalasia. In the period 2010-2012 we observed 64 patients, of whom 19 were referred for medical treatment. Three of Introduction Achalasia is a not frequent esophageal motor disor- der that affects both the body of the esophagus and the lower esophageal sphincter (LES). It…
Single-Nucleotide Polymorphism Array-Based Characterization of Ring Chromosome 18
2012
Objective To study genotype–phenotype correlation of ring chromosome 18 [r(18)] in 9 patients with 46,XN karyotype. Study design In 9 patients with a de novo 46,XN,r(18) karyotype (7 females, 2 males), we performed high-resolution single-nucleotide polymorphism array analysis (Illumina Human Omni1-QuadV1 array in 6 patients, Affymetrix 6.0 array in 3 patients), investigation of parental origin, and genotype–phenotype correlation. Results No breakpoint was recurrent. Single metaphases with loss of the ring, double rings, or secondarily rearranged rings were found in some cases, but true mosaicism was present in none of these cases. In 3 patients, additional duplications in 18p (of 1.4 Mb, 2 …
Predicting Professional Quality of Life and Life Satisfaction in Spanish Nurses: A Cross-Sectional Study
2020
Background: Dealing with suffering, grief, and death on a daily basis, together with the particular working conditions, may produce high levels of burnout in nurses, and hinder their well-being. The purpose of this research is to study the effect of self-care and self-compassion on nurses&rsquo
Identifying associations between diabetes and acute respiratory distress syndrome in patients with acute hypoxemic respiratory failure: an analysis o…
2018
Background: Diabetes mellitus is a common co-existing disease in the critically ill. Diabetes mellitus may reduce the risk of acute respiratory distress syndrome (ARDS), but data from previous studies are conflicting. The objective of this study was to evaluate associations between pre-existing diabetes mellitus and ARDS in critically ill patients with acute hypoxemic respiratory failure (AHRF). Methods: An ancillary analysis of a global, multi-centre prospective observational study (LUNG SAFE) was undertaken. LUNG SAFE evaluated all patients admitted to an intensive care unit (ICU) over a 4-week period, that required mechanical ventilation and met AHRF criteria. Patients who had their AHRF…
Assessment of Pulmonary Mechanics and Gastric Inflation Pressure During Mask Ventilation
1995
AbstractIntroduction:Mask ventilation is a procedure routinely used in emergency medicine. Potential hazards are inadequate alveolar ventilation and inflation of the stomach with air, leading to subsequent regurgitation and aspiration. The aim of this study was to measure lung function and gastric inflation pressures during mask ventilation.Methods:For this purpose, 31 patients scheduled for routine urological procedures were studied during induction of anesthesia. Lung function was assessed by recording respiratory flow and pressure directly at the face mask. Gastric inflation was observed with a microphone taped to the epigastric area.Results:Gastric inflation occurred in 22 of the 31 pat…
Endoluminal therapy of GERD with a new endoscopic suturing device
2005
Background Endoscopic, endoluminal therapy might be an alternative treatment option in light of the costs of proton pump inhibitor therapy and possible complications after laparoscopic surgery. The aim of the current study was to assess the efficacy and the safety of a new endoluminal suture device (ESD) in pig models and humans. Secondly, 3 and 6 months' follow-ups were performed, and possible complications and their management were evaluated. Methods In the preclinical phase of the study, suturing procedures were practiced and evaluated in 8 pig models (Erlanger Endo Trainer). In the clinical phase, 20 patients with mild esophagitis, small or no hiatal hernia, and signs of abnormal acid e…
Muscle tone in different joint positions and at submaximal isometric torque levels
2007
The aim was to evaluate the tone and electric activity of the quadriceps muscle at rest and different torque levels. The second aim was to study whether thickness of soft tissues and change in the joint position would affect muscle tone. Eighteen healthy subjects participated. Computerized muscle tonometer (CMT) and surface electromyography (sEMG) measurements were performed: seated, first at rest with leg straight and then with the knee at 60 degrees . Thereafter measurements were obtained at levels of 80, 60, 40 and 20% of the maximum isometric torque at the same knee angle. Thickness of skin, subcutis and muscle was measured by ultrasound. The CMT values taken were the depth the indenter…
The Value of Scoring Achalasia: A Comparison of Current Systems and the Impact on Treatment–The Surgeon's Viewpoint
2007
Heller myotomy in patients with achalasia promises better long-term success than pneumatic dilation, especially in younger patients, and therefore has evolved as the primary treatment option. The aim of this study was to evaluate the impact of different disease-specific severity scores on achalasia treatment. Fifty consecutive patients undergoing pneumatic dilation (n = 25) or myotomy (n = 25) were assessed pre- and postinterventionally by clinical evaluation using the Eckardt Score, the Vantrappen Classification, and the Adams's Stages, as well as by radiologic and manometric studies and by subjective evaluation. The Eckardt Score and the Vantrappen Classification correlated significantly…
Achalasia—an unnecessary long way to diagnosis
2015
Although achalasia presents with typical symptoms such as dysphagia, regurgitation, weight loss, and atypical chest pain, the time until first diagnosis often takes years and is frustrating for patients and nevertheless associated with high costs for the healthcare system. A total of 563 patients were interviewed with confirmed diagnosis of achalasia regarding their symptoms leading to diagnosis along with past clinical examinations and treatments. Included were patients who had undergone their medical investigations in Germany. Overall, 527 study subjects were included (male 46%, female 54%, mean age at time of interview 51 ± 14.8 years). Dysphagia was present in 86.7%, regurgitation in 82…
