Axial loading and posture cues in contraction of transversus abdominis and multifidus with exercise
2020
AbstractAstronauts are at increased risk of spine injury. With a view to developing training approaches for the muscles of the spine in microgravity, this study examined the effects of axial loading and postural cues on the contraction of transversus abdominis and lumbar multifidus in supine lying using a novel exercise device (GravityFit). Thirty (18 males and 12 females) endurance-trained runners without a history of spinal pain aged 33–55 years were recruited. Magnetic resonance imaging (MRI) was performed under one rest and five exercise conditions, which involved variations in axial loading and postural cues. Whole volume of the abdominal and lumbar paraspinal muscles was imaged and tr…
Double-Balloon Enteroscopy: Preliminary Experience in Patients with Obscure Gastrointestinal Bleeding or Chronic Abdominal Pain
2003
Background and Study Aims: Even in the era of capsule endoscopy, diseases of the small bowel are sometimes difficult to diagnose, and endoscopic treatment is not possible without surgical laparotomy. The new method of carrying out enteroscopy using a double-balloon technique allows not only diagnostic but also therapeutic endoscopic interventions for lesions in the small bowel. Preliminary experience with this new method is reported here. Patients and Methods: Between the end of March 2003 and August 2003, eight patients (four women, four men; mean age 59 ± 23 years, range 20 - 90) with chronic gastrointestinal bleeding or abdominal pain, or both, underwent enteroscopy using the double-bal…
Impact of fluoroscopy on oral double-balloon enteroscopy: results of a randomized trial in 156 patients
2010
Background and study aims The routine utility of fluoroscopy during double-balloon enteroscopy (DBE) via the oral route has been not prospectively evaluated. Up to now, there have been no prospective randomized trials to assess whether fluoroscopy improves outcomes. The aim of this study was to assess the value of fluoroscopy during oral DBE. Patients and methods A total of 156 patients (88 men, 56.4 %) of mean (standard deviation [SD]) age 56 (19) years were randomly assigned to undergo oral DBE either with or without fluoroscopy. The majority of the patients had obscure gastrointestinal bleeding (n = 96, 62 %). The primary target criteria for the study were postpyloric insertion depth and…
Testing a model of physical activity and obesity tracking from youth to adulthood: the cardiovascular risk in young Finns study
2006
To test a potential model of the relationship between physical activity and obesity from youth to adulthood.Longitudinal study data from the cardiovascular risk in young Finns study.A total of 1319 boys (n=626) and girls (n=693) aged 9, 12, 15 and 18 years were randomly selected from five university towns and their rural surroundings in 1980. They were followed up for 21 years. In 2001 they were 30, 33, 36 and 39 years old.Physical activity was assessed by a short questionnaire at two measurement points. Obesity was measured by body mass index (BMI) and sum of skinfolds in 1980 and BMI and waist circumference in 2001.Structural equation analysis (LISREL) indicated that the prevalence of abd…
Histological findings in direct inguinal hernia
2013
Abstract BACKGROUND: The study is focused on recognizing the histological changes of the structures close to and around the hernia opening in patients having direct inguinal hernia. METHODS: In 15 patients with primary bilateral direct inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, tissue specimens from the abdominal wall surrounding a direct hernia border were excised for histological examination. These findings in patients with direct inguinal hernia were compared with tissue specimens excised from the fossa inguinalis media of cadavers without hernia. RESULTS: Significant degenerative modifications such as fibrohyaline degeneration and fatty substitution of…
Identification of a Unique Helicobacter Species by 16S rRNA Gene Analysis in an Abdominal Abscess from a Patient with X-Linked Hypogammaglobulinemia
2000
ABSTRACT A unique Helicobacter species, MZ640285, was isolated from a patient with X-linked hypogammaglobulinemia suffering from recurrent abdominal abscesses and was identified by 16S rRNA gene sequence analysis. In the phylogenetic tree, the isolate fell into a cluster which included Flexispira rappini , Helicobacter bilis , and Helicobacter sp. strain Mainz. Helicobacters are being increasingly recognized as pathogens in immunocompromised hosts. These fastidious bacteria are not easily cultured in the routine diagnostic laboratory, and this is the first report of their identification by 16S rRNA gene sequencing performed directly from a clinical specimen.
Epidemiological and clinical features of norovirus gastroenteritis in outbreaks: a population-based study
2009
AbstractNoroviruses are the most frequent cause of acute gastroenteritis in the community. In Catalonia, it is not clear how this type of viral gastroenteritis is evolving, and the objective of this prospective population-based study was to describe the incidence and epidemiological and clinical features of outbreaks of acute gastroenteritis due to norovirus in Catalonia between October 2004 and October 2005. Incidence rates were calculated using the estimated population of Catalonia in 2005. For each outbreak, the mode of transmission, the number of persons affected, demographic variables, clinical presentation, the date and time of onset of symptoms and the duration of symptoms, physician…
Endoscopic Neurosurgery and Endoscope-assisted Microneurosurgery for the Treatment of Intracranial Cysts
1998
Objective Different endoscopic techniques have been introduced into neurosurgery, but accepted terminology and definitions are still missing. We propose a terminology based on whether the endoscope is used alone or in conjunction with an operating microscope and on whether the route of surgical manipulations is through or outside the endoscope. Accordingly, procedures are categorized into endoscopic neurosurgery (EN), endoscope-assisted microneurosurgery (EAM), and endoscope-controlled microneurosurgery (ECM). Methods We treated 36 patients with intracranial arachnoid cysts (ACs) and intraventricular cysts endoscopically. The patients ranged in age from 4 months to 69 years (mean age, 31 yr…
Follow-up after transanal endoscopic microsurgery or transanal excision of large benign rectal polyps
1998
Methods: Between January 1986 and December 1995, 238 patients with benign rectal polyps under-went either transanal endoscopic microsurgery (n = 226) or transanal excision (n = 12) at the Clinic of General and Abdominal Surgery, Johannes Gutenberg-University, Mainz. Results: Mean polyp size was 4.2 cm; 89.1% of polyps measured more than 2 cm in diameter. In 89.1% of cases, histological analysis revealed polyps containing tubulovillous or villous adenomas. Synchronous colonic polyps were detected in 12.5% of patients. Follow-up data are available on 222 patients (94%). At follow-up examination, 169 of the 193 surviving patients (87.6%) were recurrence free. Seven of 193 patients (3.6%) had d…
Functional pain in hospitalised and school children
2012
Aim. Aim of the study was to recognise the role of psychological disagreement in children and adolescents suffering from functional pain. Methods. Two groups of children, adolescents and their parents were interviewed: group H (hospitalized patients), group S (students, at school). Suitable investigations excluded organic lesions. The following data were analysed: 1) presence of pain in relation with: i) sex and age; ii) relation with parents, brothers, other relatives, schoolfellows; 2) efficacy of possible treatments. Results. Group H: 194 patients, median age 10 years; 134 referred pain: 62 out of 92 males and 72 out of 102 females; location of pain: abdomen, limbs, head, back. Family di…
