- 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.

- 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.

- 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.

- 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.

- The distribution of peptide-containing nerve fibers in the pharyngeal region of rabbits was studied by immunocytochemistry. Neuropeptide Y (NPY)-containing fibers were numerous around blood vessels and moderate in number among bundles of striated muscle fibers. A few NPY-containing fibers were seen around seromucous glands and beneath the epithelium. Nerve fibers containing vasoactive intestinal peptide (VIP) were numerous around seromucous glands and moderate in number around blood vessels, bundles of muscle, and in the subepithelial layer. A few nerve fibers containing substance P (SP) were seen around blood vessels, seromucous glands, among bundles of muscle, and in the subepithelial layer. Nerve fibers containing calcitonin gene-related peptide (CGRP) were numerous. They were distributed close to blood vessels, among bundles of muscle, in the subepithelial layer, and within the epithelium. A conspicuous finding was the occurrence of CGRP within motor end plates of striated muscle.

- Background: Staging of rectal cancer with MRI has major impact on treatment choice and may be of importance in new cancer management strategies such as “wait-and-see” policy. Purpose: To assess the reproducibility of a software package recently developed at our department to measure volumes, apparent diffusion coefficient, and the skewness of apparent diffusion coefficient in lymph nodes and tumors in rectal cancer patients before and after chemoradiation treatment. Material and Methods: This study included 20 consecutive patients with biopsy-verified rectal cancer, in whom MRI staging had been performed both before and after chemoradiation treatment. The diffusion-weighted images were transferred to the software. The volume, apparent diffusion coefficient, and skewness were determined for 93 lymph nodes and 40 tumors. The volumes were compared with manual measurements of the volume of the same lymph nodes and tumors. Results: The agreement in semi-automatic measurements of lymph nodes was very good (ICC = 0.99), and in tumors good (ICC = 0.88). The agreement in manual measurements of lymph nodes was very good (ICC = 0.95) when all lymph nodes were included, but low (ICC = 0.52) if three outliers were excluded. Bland–Altman plots showed clear agreement between manual and semi-automatic measurements in the lymph nodes, but not in measurements of tumors. The values of apparent diffusion coefficient and skewness in tumors differed before and after treatment but did not differ in lymph nodes as a group. Conclusion: The software package showed a high degree of reproducibility in measurements on lymph nodes but requires further development to improve the reproducibility of tumor measurements.
