- 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.

- Dysphagia is a common symptom in stroke patients, and malnutrition is prevalent among these patients. Thus far, nutritional effects of dysphagic treatment have not been evaluated. The aim of the present report was to study the effects of swallowing techniques on nutritional and anthropometric variables. A survey with follow-up was performed at the Departments of Geriatric Medicine and Neurology, Malmo University Hospital, Sweden. Thirty-eight stroke patients, 53-89 years of age, with subjective complaints of dysphagia and oral/pharyngeal dysfunction according to videofluoroscopic barium swallowing examination (VSBE), were given swallowing treatment. The treatment included oral motor exercise, different swallowing techniques, positioning, and diet modification. Plasma protein levels, body composition, VSBE, and a viso-analogical scale for subjective complaints were repeated before and after treatment. At baseline, 94% of cases had signs of penetration and 50-72% had plasma protein levels below recommended levels. Treatment reduced the degree of oral dysfunction, (dissociation) and pharyngeal dysfunction (penetration and constrictor paresis). Sixty percent of cases showed an improved overall VSBE score, and improved levels of albumin and total iron-binding capacity were restricted to this group. In cases with unchanged or decreased VSBE score, body weight was reduced and a negative correlation to total iron-binding capacity was noted (r = -0.60, p < 0.05). Changes of subjective complaints did not correlate with swallowing function or nutritional improvements. Swallowing treatment improves swallowing function, and improved swallowing function is associated with improvements in nutritional parameters. Subjective complaints is not sufficient to evaluate the clinical course, and nutritional parameters should be monitored in patients with oral or pharyngeal dysfunction.

- BACKGROUND: Screening for inflammatory small bowel disease has hereto relied on barium examination, usually performed after duodenal intubation. A noninvasive technique for imaging of the small bowel in such patients would be preferable. METHODS: A total of 59 patients were included in the study. A small bowel barium examination (SBE) was performed after duodenal intubation using a barium and air double-contrast technique. Ultrasound (US) of the right lower quadrant was performed with a 3.5- or 5-MHz transducer. The patients fasted overnight. RESULTS: In 37 of 39 patients with a normal SBE, US was also normal. In 20 patients, SBE showed lesions compatible with Crohn disease and in 18 of these the US study showed thickening of the bowel wall. One of these patients later tested positive for Yersinia enterocolitica. There were two false-positive and two false-negative US examinations. For detection of inflammatory disease of the small bowel, US was calculated to have a sensitivity of 0.95, specificity of 0.93, accuracy of 0.93, predictive value of a positive test was 0.90, and a predictive value of a negative test was 0.95. CONCLUSIONS: US, therefore, seems to be a reliable method in the workup of patients suspected of having inflammatory small bowel disease. Thereby, US probably can select patients for SBF.

- OBJECTIVE: To find out the prevalence of symptomatic non-palpable groin hernias in women under 40 years old with undiagnosed chronic groin pain. DESIGN: Retrospective analysis. SETTING: University hospital, Sweden. SUBJECTS: 116 women 14-39 years old (mean 27) with chronic undiagnosed groin pain who underwent herniography 1977-1994. INTERVENTIONS: Intraperitoneal injection of 80 ml iodine contrast medium (200 mg I/ml) RESULTS: Hernias were found in 28 patients (24%): 17 in the right groin alone, 6 in the left groin alone and 5 bilaterally. 19 patients had hernias on the symptomatic side only. 17 patients had indirect inguinal hernias and 7 had direct inguinal hernias (which are claimed to be extremely rare in women). CONCLUSION: A hernia is a relatively common finding during herniography in young women with groin pain.

Tidskriftsartikel (refereegranskat)abstract
- This is a prospective study of 100 consecutive stroke patients. Within 24 h after stroke onset they were asked specifically about swallowing complaints and subjected to a clinical examination including neurologic examination, Mini-Mental test, and Barthel score. Dysphagic patients were examined with the repetitive oral suction swallow test (the ROSS test) for quantitative evaluation of oral and pharyngeal function at 24 h, after 1 week, and after 1 month. At 6 months, the patients were interviewed about persistent dysphagia. Seventy-two patients could respond reliably at 24 h after the stroke onset and 14 of these complained of dysphagia. Non-evaluable patients were either unconscious, aphasic, or demented. The presence of dysphagia was not influenced by age or other risk factors for stroke. Facial paresis, but no other clinical findings, were associated with dysphagia. Dysphagia 24 h after stroke increased the risk of pneumonia but did not influence the length of hospital stay, the manner of discharge from hospital, or the mortality. The initial ROSS test, during which the seated patient ingests water through a straw, was abnormal in all dysphagic stroke patients. One-third of the patients were unable to perform the test completely. Above all, dysfunction was disclosed during forced, repetitive swallow. All phases of the ingestion cycle were prolonged whereas the suction pressures, bolus volumes, and swallowing capacities were low. Abnormalities of quantitative swallowing variables decreased with time whereas the prevalences of swallowing incoordination and abnormal feeding-respiratory pattern became more frequent. After 6 months, 7 patients had persistent dysphagia. Five of these were initially non-evaluable because of unconsciousness, aphasia, or dementia.

Oral function test for monitoring suction and swallowing in the neurologic patient
- 1995

Ingår i: Dysphagia. - 1432-0460. ; 10:2, s. 93-100

Tidskriftsartikel (refereegranskat)abstract
- Disturbances in swallowing are common in neurologic disease but difficult to evaluate in the clinical setting. Fundamental variables such as bolus volume, swallow capacity (volume ingested over time), and the relation between ingestion and time for important events in oral and pharyngeal swallowing have not been sufficiently studied. We therefore employed a composite method for monitoring oral and pharyngeal swallowing function: the test of Repetitive Oral Suction Swallow (the ROSS test). The technical details are described as well as preliminary results from a pilot study of 20 healthy subjects and 5 patients with neurologic swallowing impairment. The correlation with respect to time sequences for major events in bolus ingestion and oral processing as monitored by the ROSS test and by videoradiography is explained. With this simple and rapid bedside test, the immediate and long-time result of therapeutic interventions in dysphagic patients may be monitored.

- Recent technological advances in manometry, including solid state transducers and computerized analysis, allows for reliable interpretation of intraluminal pharyngeal pressures. Simultaneous videoradiography (barium swallow) provides fluoroscopic control of the manometric sensors (videomanometry), thereby eliminating the uncertainty of sensor dislocation during laryngeal elevation. This is the first study describing normal manometric parameters in videomanometry during barium swallow. Seven manometric parameters and six videoradiographic parameters were analyzed. We included 25 nondysphagic volunteers with normal videoradiographic parameters in the study. The examination was performed in an upright physiologic position during 10-ml barium and dry swallows. Mean resting pressure in the upper esophageal sphincter was 89.6 +/- 32.6 (+/- 2 SD) mmHg. Mean residual pressure during relaxation of the upper esophageal sphincter was 7.2 +/- 8.0 (+/- 2 SD) mmHg during barium swallow and 3.8 +/- 6.2 (+/- 2 SD) mmHg during dry swallow. The mean duration of upper esophageal sphincter relaxation was 601 +/- 248 (+/- 2 SD) msec. The mean peristaltic contraction of the upper esophageal sphincter was 253.8 +/- 142.8 (+/- 2 SD) mmHg. Fourteen (56%) of the 25 had a measurable intrabolus pressure (mean 33.2 +/- 17.3 mmHg) at the level of the inferior pharyngeal constrictor. A specific finding was discovered when the epiglottis tilts down hitting the manometric sensor. This epiglottic tilt was identified in 7 subjects (28%) and caused pressures of around 600 mmHg. A standardized manometric technique is important in videomanometry, and normal values as described in this study are essential in clinical use.

Ingår i: Dysphagia. - 1432-0460. ; 10:1, s. 44-48

Tidskriftsartikel (refereegranskat)abstract
- The pathogenetic mechanisms causing esophageal dysmotility is not well understood. We examined 13 patients with solid bolus dysphagia in a radiologic barium study including the swallowing of a 14-mm tablet. In all 13 patients the tablet was caught in the proximal or midesophagus. In 8 patients, the entrapment was associated with symptoms (Group 1) whereas in 5 patients (Group 2), no symptoms were reported. All 13 patients together with a control group of 56 healthy, nondysphagic subjects were tested for autonomic nerve function. Autonomic nerve function tests included registration of electrocardiographic R-R interval variation during deep breathing test (E/I ratio), a test of parasympathetic, vagal, nerve function. The results showed that the E/I ratio was significantly lower in patients with symptoms of bolus-specific esophageal dysmotility (-2,19 [1.76]) (median [interquartile range]) compared with patients without symptoms (0.05 [2, 87], p = 0.0192) and controls (-0.25 [1.26], p = 0.0009). In conclusion, symptomatic bolus-specific esophageal dysmotility is associated with vagal nerve dysfunction.
