- Aims Gastroparesis is a common gastrointestinal complication in diabetes mellitus, whereas dysfunction in the other gastrointestinal organs has been less thoroughly investigated. Furthermore, it is not known whether there is any relationship between motility and dysmotility between these organs. The aim of this study was to examine whether diabetic patients with gastrointestinal symptoms also have motility disturbances in the oesophagus and stomach and, if so, whether there are any associations between these disturbances. Methods Thirty-one patients with diabetes mellitus who complained of gastrointestinal symptoms were asked to complete a questionnaire about their symptoms. They were further investigated with oesophageal manometry and gastric emptying scintigraphy. Results Fifty-eight per cent of the patients had abnormal oesophageal function, and 68% had delayed gastric emptying. Abdominal fullness was the only symptom that related to any dysfunction, and it was associated with delayed gastric emptying (P = 0.02). We did not find any relationship in motility or dysmotility between the oesophagus and the stomach. Conclusion Oesophageal dysmotility, as well as gastroparesis, are common in patients with diabetes who have gastrointestinal symptoms. It is important to investigate these patients further, to be able to reach an accurate diagnosis and instigate appropriate treatment. Our findings indicate that the oesophagus and the stomach function as separate organs and that pathology in one does not necessarily mean pathology in the other.

Effect of Barium Sulfate Contrast Medium on Rheology and Sensory Texture Attributes in a Model Food
- 2009
-
In: Acta Radiologica. - : SAGE Publications. - 0284-1851 .- 1600-0455. ; 50:2, s. 131-138
-
Journal article (peer-reviewed)abstract
- Background: The swallowing process can be visualized using videoradiography, by mixing food with contrast medium, e.g., barium sulfate (BaSO4), making it radiopaque. The sensory properties of foods may be affected by adding this medium. Purpose: To evaluate if and to what extent sensory and rheological characteristics of mango puree were altered by adding barium sulfate to the food. Material and Methods: This study evaluated four food samples based on mango puree, with no or added barium sulfate contrast medium (0%, 12.5%, 25.0%, and 37.5%), by a radiographic method, and measured sensory texture properties and rheological characteristics. The sensory evaluation was performed by an external trained panel using quantitative descriptive analysis. The ease of swallowing the foods was also evaluated. Results: The sensory texture properties of mango puree were significantly affected by the added barium in all evaluated attributes, as was the perception of particles. Moreover, ease of swallowing was significantly higher in the sample without added contrast medium. All samples decreased in extensional viscosity with increasing extension rate, i.e., all samples were tension thinning. Shear viscosity was not as dependent on the concentration of BaSO4 as extensional viscosity. Conclusion: Addition of barium sulfate to a model food of mango puree has a major impact on perceived sensory texture attributes as well as on rheological parameters.

Quantitative assessment of swallowing in healthy adults
- 1996
-
In: Dysphagia. - 1432-0460. ; 11:2, s. 110-116
-
Journal article (peer-reviewed)abstract
- Swallowing has hitherto been evaluated during physical examination, radiologic barium studies, manometry, and cervical auscultation. Radiography principally demonstrates qualitative aspects of oral and pharyngeal function, whereas quantitative aspects have primarily been documented by manometry. To evaluate swallowing quantitatively, without using invasive methods or radiation, we have applied a combined test of water drinking, i.e., the Repetitive Oral Suction Swallow test (ROSS). The test provides reliable measurements of suction pressure, bolus volume, timing of important events in oral and pharyngeal swallow, and respiration. The test is described and results from 292 healthy, non-dysphagic subjects are presented. We found a mean bolus volume of 25.6 +/- 8.5 ml during single swallow and 21.1 +/- 8.2 ml during stress (forced, repetitive swallow). During forced, repetitive swallow, the bolus volume was more strongly associated with suction time (r2 = 0.55) than with peak suction pressure (r2 = 0.04), indicating that suction time is more important than suction pressure in determining the bolus volume. The oral-pharyngeal transit time decreased: single swallow 0.56 +/- 0.36 sec, forced repetitive swallow 0.23 +/- 0.11 sec, as did the coefficient of variation (48% and 64%, respectively) indicating a more automatic neural process for pharyngeal function in forced, repetitive swallow. The postswallow respiration started with inspiration in 10% of studied individuals, but did not correlate with deviations in other variables in the test. Thus, postswallow inspiration must be considered as normal. The ROSS test offers a rapid and easy quantitative assessment of swallowing.

Journal article (peer-reviewed)abstract
- Aims/hypothesis Among diabetic patients, glucose homeostasis may be affected by abnormal gastrointestinal motility and autonomic neuropathy. This study analysed whether oesophageal dysmotility, delayed gastric emptying or autonomic neuropathy affect glucose homeostasis. Materials and methods Oesophageal manometry and gastric emptying scintigraphy were performed in 20 diabetic patients. Heart-rate variation during deep breathing (expiration/inspiration [E/I] ratio) and continuous subcutaneous glucose concentrations for a period of 72 h were also monitored in the same patients. Results Oesophageal dysmotility was found in eight of 14 patients. Eleven of 20 patients had delayed gastric emptying (abnormal gastric emptying half-time [T (50)]) and nine of 18 had an abnormal E/I ratio. Complaints of abdominal fullness were predictive of delayed gastric emptying. A low peristaltic speed of the oesophagus was associated with impaired T (50) (r (s) =-0.67; p=0.02). One hour after breakfast, subcutaneous glucose levels decreased in patients with delayed gastric emptying but continued to rise in those with normal emptying. Consequently, the median glucose level 2.5 h after breakfast was lower in the former (9.1 [4.2-12.5] vs 14.3 [11.2-17.7] mmol/l; p < 0.05). Glucose fluctuations during the 72 h were significantly higher in patients with an abnormal E/I ratio than in those with a normal E/I ratio (coefficient of variation: 41 [46-49] vs 28 [27-34]%; p=0.008). Conclusions/interpretation Abdominal fullness predicted delayed gastric emptying that was associated with diminished glucose uptake after breakfast. Low oesophageal peristaltic speed was associated with slow gastric emptying whereas parasympathetic neuropathy was associated with increased glucose variations.

Videomanometric aspects of pharyngeal constrictor activity
- 1996
-
In: Dysphagia. - 1432-0460. ; 11:2, s. 83-86
-
Journal article (peer-reviewed)abstract
- Pressure changes were registered with videomanometry (simultaneous manometry and barium swallow) in the pharynx and in the pharyngoesophageal segment (PES) during swallowing. A considerable longitudinal asymmetry was found. Peak pressure was highest in the PES, lower in the inferior constrictor area, and lowest at the level of the tongue base. The rate of pressure rise was highest at the level of the PES. The speed of propagation of the contraction wave was 13 (+/- 2) cm/sec. There was no correlation between the measured variables (i.e., peak pressure, rate of pressure rise, and speed of contracting wave). Our findings can partly be explained by different mechanical constraints at different levels of the pharynx but may also reflect the organization of neural control of swallowing in the brainstem. Knowledge of transducer position and orientation is essential for the evaluation of pharyngeal pressure during swallowing. Such knowledge is best achieved by performing manometry simultaneously with fluoroscopy, i.e., videomanometry.

CT Angiography Followed by Endovascular Intervention for Acute Superior Mesenteric Artery Occlusion does not Increase Risk of Contrast-Induced Renal Failure.
- 2010
-
In: European journal of vascular and endovascular surgery. - : Elsevier BV. - 1532-2165 .- 1078-5884. ; 39, s. 726-730
-
Journal article (peer-reviewed)abstract
- OBJECTIVES: Acute superior mesenteric artery (SMA) occlusion can be diagnosed in an early phase by computed tomography (CT) angiography, which is also a prerequisite for endovascular intervention. However, the issue of development of postoperative permanent renal failure due to contrast-induced nephropathy has not been evaluated. DESIGN: Retrospective MATERIALS: A total of 55 patients with acute SMA occlusion were retrieved from the in-hospital register during a 4-year period between 2005 and 2009. METHODS: Glomerular filtration rate was calculated as a simplified variant of Modification of Diet in Renal Disease Study Group (MDRD). RESULTS: Preoperative renal insufficiency was found in 52%; advanced state in one patient. Creatinine was lower (p = 0.018) at discharge (median: 71 mumol L(-1)), compared to admission (median: 76 mumol L(-1)), in the 32 survivors exposed to repeated iodinated contrast media (median: 54.7 g iodine). No patient died due to renal failure or needed dialysis after endovascular intervention. Endovascular intervention was associated with a higher survival rate (p = 0.001). CONCLUSION: Serious acute contrast-induced nephropathy was not found in patients diagnosed by CT angiography and treated by endovascular procedures for acute SMA occlusion. Elevated serum creatinine levels should not deter the clinician from ordering a CT angiography in patients with suspicion of acute SMA occlusion.

Journal article (peer-reviewed)abstract
- BACKGROUND: Reports on trends in incidence and mortality of acute superior mesenteric artery (SMA) occlusion and evaluation of prognostic factors in recent years are lacking. METHODS: Patients with acute SMA occlusion were identified through the in-patient and autopsy registry between 1970 and 1982 (n = 270), 1987 to 1996 (n = 135), and 2000 and 2006 (n = 100) in Malmö, Sweden. RESULTS: The overall incidence rate decreased from 8.6 to 5.4/100,000 person years and the autopsy rate from 87% to 25% over time. A higher serum creatinine level was associated with a lower probability of undergoing multi-detector row computed tomography with intravenous contrast (MDCTiv) (p = 0.006). Not performing a MDCTiv (odds ratio 4.0; 95% confidence interval [1.0-16.0]) remained as independent prognostic factor for in-hospital mortality. General and vascular surgeons collaborated in 25 out of 61 patients that underwent an intervention, of which 21 (84%) (p < 0.001) survived. CONCLUSIONS: A close collaboration between radiologists and general and vascular surgeons seems to be most important to lower the mortality in patients with acute SMA occlusion.

Epidemiology, risk and prognostic factors in mesenteric venous thrombosis.
- 2008
-
In: British Journal of Surgery. - : Oxford University Press (OUP). - 1365-2168 .- 0007-1323. ; Aug 21, s. 1245-1251
-
Journal article (peer-reviewed)abstract
- BACKGROUND:: Epidemiological reports on risk and prognostic factors in patients with mesenteric venous thrombosis (MVT) are scarce. METHODS:: Patients with MVT were identified through the inpatient and autopsy registry between 2000 and 2006 at Malmö University Hospital. RESULTS:: Fifty-one patients had MVT, diagnosed at autopsy in six. The highest incidence (11.3 per 100 000 person-years) was in the age category 70-79 years. Activated protein C resistance was present in 13 of 29 patients tested. D-dimer at admission was raised in all five patients tested. Multidetector row computed tomography (CT) in the portal venous phase was diagnostic in all 20 patients investigated, of whom 19 were managed conservatively. The median length of resected bowel in 12 patients who had surgery was 0.6 (range 0.1-2.2) m. The overall 30-day mortality rate was 20 per cent; intestinal infarction (P = 0.046), treatment on a non-surgical ward (P = 0.001) and CT not done (P = 0.022) were associated with increased mortality. Cancer was independently associated with long-term mortality: hazard ratio 4.03, 95 per cent confidence interval 1.03 to 15.85; P = 0.046. CONCLUSION:: Portal venous phase CT appeared sensitive in diagnosing MVT. As activated protein C resistance was a strong risk factor, lifelong anticoagulation should be considered.

Prospective Study on Diagnostic Performance of Color Doppler Ultrasound Using Trans-stenotic Mean Arterial Pressure Gradient as a Reference in Stented Superior Mesenteric Artery
- 2019
-
In: Annals of Vascular Surgery. - : Elsevier BV. - 0890-5096. ; 56, s. 294-302
-
Journal article (peer-reviewed)abstract
- Background: The aim of this study was to evaluate the diagnostic performance of color Doppler ultrasound (CDU) after stenting of superior mesenteric artery (SMA) stenosis using mean arterial pressure (MAP) gradients as a reference method. Methods: This is a prospective study. Thirty-one patients underwent 51 paired measurements of MAP gradients and CDU after endovascular intervention with endoprosthesis in the SMA for mesenteric atherosclerotic disease between March 2009 and July 2016. Results: Peak systolic velocities (PSVs; r = 0.44, P = 0.001) and end-diastolic velocities (EDVs; r = 0.59, P < 0.001) correlated with MAP gradients. The area under the receiver-operating characteristics curve for diagnosis of significant in-stent stenosis for different threshold values of PSV and EDV using MAP gradient of ≥10 mm Hg as reference was 0.75 and 0.80, respectively. Sensitivity and specificity for PSV >3.3 m/s were 43.5% (95% confidence interval [CI] 23.2–63.7) and 92.9% (95% CI 83.3–100.0), respectively. Sensitivity and specificity for EDV >0.50 m/s were 63.6% (95% CI 43.5–83.7) and 92.3% (95% CI 82.1–100.0), respectively. Specificity and positive predictive value were both 100% for combined PSV >3.0 m/s and EDV >0.5 m/s. Conclusions: PSV and EDV were equally useful in evaluation of significant SMA stent stenosis, when using trans-stenotic MAP gradient as reference. Finding of a significant stenosis on CDU should be considered as a true significant SMA stent stenosis.

Treatment of cricopharyngeal dysfunction: a comparative pilot study.
- 2015
-
In: BMC Research Notes. - : Springer Science and Business Media LLC. - 1756-0500. ; 8
-
Journal article (peer-reviewed)abstract
- Cricopharyngeal dysfunction is a narrowing at the level of the upper oesophageal sphincter caused by failed or incomplete sphincter opening as a result of lack of pharyngoesophageal coordination or reduction in the muscular compliance of the upper oesophageal sphincter. Oropharyngeal dysphagia is a typical symptom. Videomanometry allows direct comparison of pressure readings with dynamic anatomy during swallowing.

Journal article (peer-reviewed)abstract
- We performed ultrasonography on 32 athletes complaining of intense pain in a swollen and tender thigh or calf after a contusion or stretching trauma. The ultrasonogram was used to visualize the presence and size of a suspected hematoma. The findings included the following: 7 patients with a circumscribed, anechoic lesion compatible with a liquefied hematoma; 10 patients with a circumscribed lesion of mixed echogenicity compatible with areas of liquefied hematoma, coagulated blood, and edema; and 15 patients with a diffuse change in echogenicity of the whole muscle. The circumscribed liquefied, and mixed hematoma were more common after contusion trauma, while the diffuse type was more common after injury caused by stretching. Ultrasonography is useful in localizing the hematoma and in characterizing the different types. Differentiation is important in diagnosis and choice of treatment.

European society for swallowing disorders - European union geriatric medicine society white paper : Oropharyngeal dysphagia as a geriatric syndrome
- 2016
-
In: Clinical Interventions in Aging. - 1176-9092. ; 11, s. 1403-1428
-
Research review (peer-reviewed)abstract
- This position document has been developed by the Dysphagia Working Group, a committee of members from the European Society for Swallowing Disorders and the European Union Geriatric Medicine Society, and invited experts. It consists of 12 sections that cover all aspects of clinical management of oropharyngeal dysphagia (OD) related to geriatric medicine and discusses prevalence, quality of life, and legal and ethical issues, as well as health economics and social burden. OD constitutes impaired or uncomfortable transit of food or liquids from the oral cavity to the esophagus, and it is included in the World Health Organization’s classification of diseases. It can cause severe complications such as malnutrition, dehydration, respiratory infections, aspiration pneumonia, and increased readmissions, institutionalization, and morbimortality. OD is a prevalent and serious problem among all phenotypes of older patients as oropharyngeal swallow response is impaired in older people and can cause aspiration. Despite its prevalence and severity, OD is still underdiagnosed and untreated in many medical centers. There are several validated clinical and instrumental methods (videofluoroscopy and fiberoptic endoscopic evaluation of swallowing) to diagnose OD, and treatment is mainly based on compensatory measures, although new treatments to stimulate the oropharyngeal swallow response are under research. OD matches the definition of a geriatric syndrome as it is highly prevalent among older people, is caused by multiple factors, is associated with several comorbidities and poor prognosis, and needs a multidimensional approach to be treated. OD should be given more importance and attention and thus be included in all standard screening protocols, treated, and regularly monitored to prevent its main complications. More research is needed to develop and standardize new treatments and management protocols for older patients with OD, which is a challenging mission for our societies.

A population based screening of abdominal aortic aneurysms (AAA)
- 1991
-
In: European Journal of Vascular Surgery. - 0950-821X. ; 5:1, s. 53-57
-
Journal article (peer-reviewed)abstract
- The prevalence of abdominal aortic aneurysm (AAA) in a defined population of elderly men and its correlation to some risk factors were studied in the population cohort "men born in 1914 from Malmo". A total of 499 were invited to attend and 375 (75%) did so. The aorta could be visualised with ultrasound in 364 patients, 39 (10.7%) of whom had aneurysmal changes. The presence of an AAA was related to the findings at a general health examination undertaken 5 years previously. Tobacco and alcohol consumption, impaired lung function and a history of angina pectoris were related to the presence of an AAA. No relationship was found between an AAA and hypertension, hyperlipidaemia or hyperglycaemia. A decreased tissue elasticity as a common denominator for the lung function impairment and development of AAA is discussed.

Expansion pattern and risk of rupture of abdominal aortic aneurysms that were not operated on
- 1993
-
In: European Journal of Surgery. - 1102-4151. ; 159:9, s. 461-467
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: To analyse the outcome of selective management of patients with abdominal aortic aneurysms, the expansion patterns of the aneurysms, and the factors that influenced the rate of rupture. DESIGN: Retrospective study. SETTING: Malmo General Hospital, Lund University, Malmo, Sweden. SUBJECTS: 155 patients (96 men and 59 women) with abdominal aortic aneurysms who were not selected for operation for whatever reason were included in the study immediately after their first ultrasound scan. MAIN OUTCOME MEASURES: Mortality, expansion rate (mm/year) measured on ultrasound scan, and rate of rupture of aneurysm. RESULTS: Median aneurysmal diameter was 40 mm (range 20-80), and length (n = 106) 70 (range 28-140). The patients were followed up for a median of 3.4 years (range 0-10.2). A total of 107 patients died and in 21 the aneurysms ruptured (4 were operated on and survived). Thirteen patients were re-evaluated and operated on electively. Ultrasonography was repeated in 98 patients, the median expansion rates (mm/year) were 3.1 (diameter) and 1.9 (length). There was a significant linear relationship between initial size (diameter and length) and rate of expansion of diameter. The risk of rupture was greater in larger aneurysms that were expanding more quickly. The cumulative mortality was not affected by the 21 aneurysms that ruptured. CONCLUSION: Selective management of patients with aortic aneurysms is justified.

In: European Journal of Radiology. - 1872-7727. ; 10:3, s. 177-180
-
Journal article (peer-reviewed)abstract
- A retrospective study of 18 patients with femoral hernia assessed by herniography is presented. Although a palpable lump was present in 11 patients (61%), the diagnosis of a femoral hernia was not made before herniography. Surgical exploration was performed in 12 patients and a femoral hernia was found and repaired with beneficial outcome in 9 of them. In conclusion: herniography is of value for the diagnosis of a femoral hernia in patients with obscure groin pain.

- OBJECTIVE: To study the effect of postoperative thyroxine on the volume of the thyroid remnant after lobectomy for benign nontoxic goitre. DESIGN: Prospective, randomised study. SETTING: University hospital, Sweden. SUBJECTS: 50 consecutive patients who underwent lobectomy for benign non-toxic goitre. INTERVENTIONS: Patients were randomised postoperatively to take thyroxine 0.1 mg or placebo daily. MAIN OUTCOME MEASURES: The median volume of the remaining thyroid lobe measured by ultrasound. Serum concentrations of thyroxine, triiodothyronine (T3) and thyroid stimulating hormone (TSH) were measured preoperatively and 1, 3, 6, 12 months postoperatively. RESULTS: The median volume of the remaining lobe had increased significantly compared with preoperatively by 1 month postoperatively by 30% in the thyroxine group and 25% in the placebo group (p < 0.01). The difference between the groups was not significant. After the first month the volume did not change significantly. In the thyroxine group, the TSH concentration was unchanged and the thyroxine concentration increased significantly throughout the study. In the placebo group there was a significant increase in TSH concentration and a significant decrease in that of thyroxine at all follow-up examinations. CONCLUSIONS: There is a significant increase in the volume of the remaining thyroid 1 month after lobectomy that persisted throughout the first year. Thyroxine given in a dose that kept the serum TSH concentration at the same level as preoperatively did not seem to influence volume changes; consequently we consider that these are caused by factors other than TSH.

Grading scale of radiographic findings in the pubic bone and symphysis in athletes.
- 2003
-
In: Acta Radiologica. - : SAGE Publications. - 1600-0455 .- 0284-1851. ; 44:1, s. 79-83
-
Journal article (peer-reviewed)abstract
- Purpose: Radiographic abnormalities in the pubic bone and symphysis are often seen in athletes with groin pain. The aim was to create a grading scale of such radiologic changes. Material and Methods: Plain radiography of the pelvic ring including the pubic bone and the symphysis was performed in 20 male athletes, age 19-35, with long-standing uni- or bilateral groin pain. We used two control groups: Control group 1: 20 healthy age-matched men who had undergone radiologic examination of the pelvis due to trauma. Control group 2: 120 adults (66 men and 54 women) in 9 age groups between 15 and 90 years of age. These examinations were also evaluated for interobserver variance. Results and Conclusion: The grading scale was based on the type and the amount of the different changes, which were classified as follows: No bone changes (grade 0), slight bone changes (grade 1), intermediate changes (grade 2), and advanced changes (grade 3). The grading scale is easy to interpret and an otherwise troublesome communication between the radiologist and the physician was avoided. There was a high interobserver agreement with a high kappa value (0.8707). Male athletes with long-standing groin pain had abnormal bone changes in the symphysis significantly more frequently and more severely (p>0.001) than their age-matched references. In asymptomatic individuals such abnormalities increased in frequency with age both in men and women.

One-Year Follow-up After Open Abdomen Therapy With Vacuum-Assisted Wound Closure and Mesh-Mediated Fascial Traction
- 2013
-
In: World Journal of Surgery. - : Springer Science and Business Media LLC. - 0364-2313 .- 1432-2323. ; 37:9, s. 2031-2038
-
Journal article (peer-reviewed)abstract
- Open abdomen (OA) therapy frequently results in a giant planned ventral hernia. Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) enables delayed primary fascial closure in most patients, even after prolonged OA treatment. Our aim was to study the incidence of hernia and abdominal wall discomfort 1 year after abdominal closure. A prospective multicenter cohort study of 111 patients undergoing OA/VAWCM was performed during 2006-2009. Surviving patients underwent clinical examination, computed tomography (CT), and chart review at 1 year. Incisional and parastomal hernias and abdominal wall symptoms were noted. The median age for the 70 surviving patients was 68 years, 77 % of whom were male. Indications for OA were visceral pathology (n = 40), vascular pathology (n = 22), or trauma (n = 8). Median length of OA therapy was 14 days. Among 64 survivors who had delayed primary fascial closure, 23 (36 %) had a clinically detectable hernia and another 19 (30 %) had hernias that were detected on CT (n = 18) or at laparotomy (n = 1). Symptomatic hernias were found in 14 (22 %), 7 of them underwent repair. The median hernia widths in symptomatic and asymptomatic patients were 7.3 and 4.8 cm, respectively (p = 0.031) with median areas of 81.0 and 42.9 cm(2), respectively (p = 0.025). Of 31 patients with a stoma, 18 (58 %) had a parastomal hernia. Parastomal hernia (odds ratio 8.9; 95 % confidence interval 1.2-68.8) was the only independent factor associated with an incisional hernia. Incisional hernia incidence 1 year after OA therapy with VAWCM was high. Most hernias were small and asymptomatic, unlike the giant planned ventral hernias of the past.

- P>The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 predetermined swallowing and respiratory events and the surrounding respiratory phase pattern were studied in different body positions and during different respiratory drives. An increased respiratory drive was induced by breathing 5% CO2. The results demonstrated a highly repeatable and fixed temporal coordination of the swallowing pattern despite body position and respiratory drive. Previous studies have demonstrated a period of centrally controlled apnoea during swallowing. This apnoea period has a variable length, varying from 1 to 5 s. During increased respiratory drive, we could demonstrate a significantly shorter period of apnoea during swallowing, mainly due to an earlier resumption of respiration. The high temporal recordings in this study have revealed that swallowing during expiration is present basically in all healthy individuals. This swallowing respiratory pattern seems to be appropriate for a safe swallow. This knowledge will be used as a reference for future studies on how swallowing and respiratory coordination might be altered due to ageing and diseases.

- Background Gastrointestinal symptoms and changes in colonic transit time (CTT) are common in the population. Purpose To evaluate consecutive patients who had been examined for CTT, along with completion of a diary about laxative and drug use, lifestyle factors, and gastrointestinal symptoms, to identify possible associations with longer or prolonged CTT. Material and Methods A total of 610 consecutive patients had undergone the radiopaque marker method with an abdominal X-ray for clinical purposes. The patients had completed a diary regarding medical treatment, lifestyle factors, stool habits, and their perceived constipation and abdominal pain during the examination period. The associations between CTT and laxative use, lifestyle factors, stool habits, and symptoms were calculated by logistic regression. Results Women had longer CTT (2.5 [1.6–3.9] vs. 1.7 [1.1–3.0] days, P < 0.001), lower weekly stool frequency (6 [3–10] vs. 8 [5–12], P = 0.001), and perceived more constipation (P = 0.025) and abdominal pain (P = 0.001) than men. High coffee consumption (P = 0.045), bulk-forming (P = 0.007) and osmotic (P = 0.001) laxatives, and lower stool frequency, shaped stool, and perceived constipation (P for trend < 0.001) were associated with longer CTT. In total, 382 patients (63%) were treated with drugs affecting motility. In the 228 patients without drug treatment, longer CTT was associated with female sex and smoking, and lower frequency of symptoms and prolonged CTT were observed compared to patients using drugs. Tea, alcohol, and abdominal pain did not associate with CTT. Conclusions Female sex, coffee, smoking, drug use, infrequent stools, shaped stool, and perception of constipation are associated with longer or prolonged CTT.

- Purpose:To study survival in two groups of dysphagic patients - one group unable to elicit the pharyngeal stage of swallow (APS) and another group with pharyngeal swallow (WPS) - and to compare recommendations regarding nutrition and therapeutic strategies based on the therapeutic swallowing study. Material and Methods: In this retrospective study, the records of dysphagic patients who have undergone a therapeutic videoradiographic swallowing study (TVSS) were reviewed. Forty patients without pharyngeal swallow were matched for age and gender with 40 patients with pharyngeal swallow; altogether 80 patients were included in the study. Survival was registered at 3, 12, and 72 months after the TVSS. Results: In this study, the APS group had a significantly shorter survival time (P = 0.0030) compared to the WPS group when followed-up at 12 months. In the APS group, most patients (37.5% (15/40)) died within the 3 months after TVSS. At 72 months, 62.5% (25/40) of the patients in the APS group had died. In the WPS group, 5% (2/40) had died within 3 months and 47.4% (19/40) after 12 months. At 72 months, 52.5% (21/40) of the patients in the WPS group had died. Regarding nutritional and therapeutic recommendations based on TVSS, 34/40 in the APS group were recommended no oral intake. Eighteen naso-gastric tubes were placed directly after TVSS. The therapeutic strategies recommended were head-positioning, thermal tactile stimulation, and tongue exercises (in 8 patients). In the WPS group, all patients were recommended oral intake. Diet modification was recommended in 29 patients. The therapeutic strategies recommended were head-positioning, thermal tactile stimulation, tongue exercises, supraglottic swallow, and effortful swallow (in 24 patients). Conclusion: Patients unable to elicit the pharyngeal stage of swallow had a shorter survival time than patients with pharyngeal swallow, probably due to a more severe underlying disease. Tube feeding was more frequent in the APS group. Fewer therapeutic strategies were recommended compared to the WPS group. In the WPS group, diet modification was frequent. Several patients had different therapeutic strategies. At the end of the study, 8/40 patients (20%) in the APS group had recovered and regained the ability to elicit the pharyngeal stage of swallow. All eight had achieved active swallowing rehabilitation.
