Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…

Reliability of the Dynamic Gait Index (Finnish version) in individuals with neurological disorders

2012

To produce a Finnish version of the Dynamic Gait Index (DGI) and establish its reliability in people with neurological disorders affecting balance.A consecutive sample of 33 participants in inter-rater and 30 participants in intra-rater sample were tested. The DGI was administered in two testing sessions 1-2 h apart. Reliability was assessed with the intra-class correlation coefficient (ICC), Bland-Altman 95% limits of agreement, coefficient of reproducibility (CR), and standard error of the mean (SEM).The instructions from the original DGI were preserved during the translation process with no need for cultural adaptations. The relative reliability of the total scores proved to be high in i…

Symptomatic remission in schizophrenia patients: relationship with social functioning, quality of life, and neurocognitive performance.

2011

Abstract Purpose To investigate whether symptomatic remission relates to better outcomes in schizophrenia. Methods Seventy-six schizophrenia patients were assessed using measures of cross-sectional symptomatic remission, social functioning, subjective quality of life (QoL), and cognition. Results Most patients (53; 69.7%) were not in remission. Remitted patients presented significantly better social functioning, better self-reported QoL, insight, and lower levels of depressive symptoms. They also showed a non-significant trend for better executive function, processing speed and verbal memory. Conclusions Symptomatic remission may be a good indicator of better clinical status, social functio…

Comparing the results of a cholesterol and saturated fat screener when using two different scores.

2003

Screener are useful instruments for categorising individuals according to their nutrient intake. To accurately classify the individuals it is important to correctly analyse the screener. Therefore we compared a simple and a weighed score of a cholesterol and saturated fat (SF) screener with the cholesterol and SF intake, respectively, calculated from an extensive food frequency questionnaire. The validation results did not change when a weighed score was used instead of the simple one, indicating that a simple score does not introduce a higher amount of misclassification.

Measurement of inflammatory mediators of eosinophils and lymphocytes in blood in acute asthma: serum levels of ECP influence the bronchodilator respo…

2002

The aim of this study was to assess the relevance of immunoinflammatory markers on the response to short acting β<sub>2</sub>-agonist in acute asthma exacerbation. Thus, we measured serum eosinophil cationic protein (ECP) levels and sIL-2R at acute exacerbation in 52 adult patients with atopic asthma, and assessed forced expiratory volume in 1 s (FEV<sub>1</sub>) before and after the administration of aerosolized salbutamol. After a cumulative dose of salbutamol causing a 10% improvement in FEV<sub>1</sub> from baseline [CD10, i.e. cumulative doses of salbutamol (800 µg) causing an improvement in FEV<sub>1</sub> from baseline to 10%] the patie…

Long-term follow-up of patients with iron deficiency anemia after a close endoscopic examination of the upper and lower gastrointestinal tract.

2000

Background In patients with Iron Deficiency Anemia (IDA) occult gastrointestinal bleeding is generally investigated by bidirectional endoscopy. The aim of our study was to examine the long-term follow-up of patients with IDA where the sources of bleeding couldn't be detected despite close endoscopic and radiologic examination of the GI tract. Methods Based on the endoscopic data base we examined consecutive patients who were referred for gastrointestinal endoscopy due to IDA with a negative endoscopic (upper GI endoscopy and colonoscopy) evaluation. Further diagnostic work up (repeated endoscopy of the upper and lower GI tract by an experienced investigator, small bowel enteroclysis, push e…

Symptom-Triggered versus Standard Chlormethiazole Treatment of Inpatient Alcohol Withdrawal: Clinical Implications from a Chart Analysis

2003

To evaluate clinical effectiveness and safety of 2 different detoxification treatment protocols, a chart analysis of hospital inpatients consecutively admitted for alcohol withdrawal during one year was undertaken. Records of 33 patients receiving symptom-triggered treatment (using a modified version of the revised Clinical Institute Withdrawal Assessment for Alcohol Scale) were compared with those of patients treated by applying a fixed-dose regimen (n = 32). Patients (45.3 ± 9.8 years, 21% female) of both groups were comparable regarding illness severity, epidemiologic parameters as well as complications during the observed treatment period. Under symptom-triggered therapy, chlormethiazol…

The effect of acupuncture on oral microcirculation in healthy volunteers: an exploratory study.

2009

Background Acupuncture is a therapeutic technique currently used in the treatment of many pathologies. The aim of this study is to evaluate the potential effect of acupuncture on “in vivo” variations in oral microcirculation in healthy subjects. Methods An exploratory study was conducted on 40 healthy subjects: 20 cases (mean 55.90, SD 16.04) and 20 controls (mean 51, SD 11.91). Videocapillaroscopy was used to detect variations in oral microcirculation. This method permits an accurate and non-invasive in vivo study of the capillaries of the oral mucous. The site selected for this pilot study is the lower lip since it is the simplest to investigate and is more readily accessible. Assessments…

Adenylyl cyclase activity is increased in younger, but decreased in older, alcoholic patients after detoxification.

2000

Acute and chronic administration of ethanol leads to alterations of the adenylyl cyclase (AC) signal transduction pathway. This study examined whether the formation of cAMP by AC in lymphocytes correlates with age in alcoholic patients and in healthy controls. Blood was drawn for preparation of lymphocyte membranes and for determination of basal, GTPgammaS-stimulated, and forskolin-stimulated AC activity from 68 actively drinking alcoholic patients (age, mean +/- SD: 45 +/- 10; range: 26-69 years) after ethanol detoxification. The patients' AC activity correlated negatively with age. In contrast, no effect of age was observed in the healthy controls (age, mean +/- SD: 42 +/- 11; range: 24-6…

Associations between intracranial pressure, intraocular pressure and mean arterial pressure in patients with traumatic and non-traumatic brain injuri…

2008

Introduction: Anatomical proximity of the eye and the intracranial space is a fact but the existence of physiological and pathophysiological relationships between them is elusive. The objective of this study was to explore anatomical and pathophysiological interactions between the eye and the intracranial space and to assess clinical utility of intraocular pressure measurement in estimation of intracranial pressure in patients with brain injuries and to discover how haemodynamic instability could influence these interactions. Controversy surrounds the recent literature concerning this problem and the consensus has not been achieved. Materials and methods: We evaluated the correlation betwee…
