Abstract
Raltitrexed (Tomudex) is proven effective in metastatic colorectal cancer. Between 1998-2000, 25 patients were included in a randomized phase II study comparing raltitrexed (13 patients) and the Nordic FLv regimen (12 patients). 23 patients were evaluable for response. The overall response rate was 2/12 (1 CR, 1 PR) in the raltitrexed arm and 1/11 (1 CR) in the Nordic FLv arm, respectively. There was no difference in overall survival (raltitrexed--14.7 months, Nordic FLv--15.4 months). 23 patients were evaluable for Quality of Life (QoL) analysis. 23/25 and 17/21 questionnaires (EORTC QLQ C-30) were returned at baseline and first evaluation. Raltitrexed tended to be the most toxic regimen, when looking at nausea and vomiting, appetite loss, diarrhea and global QoL. However, most patients (65%) recommended the raltitrexed treatment schedule. The total treatment cost was equal in both arms (about 6,800 EURO/patient) and the hospital/hospital hotel stay costs accounted for more than half of it.

Abstract
Because perioperative blood transfusions have been shown to have an impaired effect on survival in patients with colorectal cancer, we examined retrospectively the records of 882 patients who had undergone curative operations: 170 patients had distant metastases at the time of operation. Of the 499 patients with colonic cancer 332 (67%) had received perioperative blood transfusions. The corresponding figure for the 213 patients with rectal cancer was 190 (89%). Colonic tumors recurred in 45% of the patients who received blood transfusions and in 39% of those who did not. Corresponding figures for tumors in the rectum were 54% and 55%. When dividing the patients with colonic cancer into different subgroups according to Dukes' grade we found differences in survival rates. The poorer survival for transfused patients was, however, only significant for those with Dukes' A tumors (p less than 0.05). This difference disappeared when the influence of age was eliminated. The estimated risk ratio of recurrence and death was 1.23 with the 95% confidence interval (0.99, 1.53) when taking Dukes' grade, current age and localization into account. Blood transfusion should be avoided if possible until adequate prospective studies have been carried out.

Abstract
A prospective controlled randomized trial testing adjuvant postoperative combination chemotherapy (5-fluorouracil, lomustine (CCNU) and vincristine) versus no adjuvant therapy in patients operated on for Dukes' C colorectal cancer is reported. In total 334 patients aged less than 70 years were recruited: 205 patients with colonic and 99 with rectal cancer, but there were three protocol violations and these cases are excluded from further consideration. Twenty-seven patients had a limited resection of their cancer. After 5 years' follow-up there was no significant difference in the tumour-free survival rate or in the survival rate between the treated and control groups. Twenty-nine of the 147 patients who started chemotherapy discontinued this treatment because of side-effects, mainly from the gastrointestinal tract. In 30 patients treatment was discontinued because of recurrent disease. The conclusion is that systemic administration of combination chemotherapy for colorectal cancer after operation is not worthwhile in routine clinical practice.

Abstract
The recurrence of peptic ulcer disease after successful treatment with 400 mg cimetidine twice daily or 1 g sucralfate four times daily was investigated in a double-blind, 1-year follow-up study. Endoscopy was performed if ulcer symptoms recurred and 2-4 and 9-11 months after endoscopically confirmed healing of the initial ulcer. No anti-ulcer medication was permitted during the follow-up period. The recurrence rates were 71% in the cimetidine group (n = 143) and 68% in the sucralfate group (n = 115) (p greater than 0.3). The rate of asymptomatic ulcer relapse was 26% in the cimetidine and 23% in the sucralfate group (p greater than 0.4). The time to relapse did not differ between the treatment groups (p greater than 0.3). In the cimetidine group smokers had a higher 12-month recurrence rate than non-smokers, 83% compared with 58% (p less than 0.01). The corresponding figures in the sucralfate group were 76% and 57% (p = 0.057). The median time to recurrence in the cimetidine-treated group was 17 weeks among smokers, compared to 43 weeks among non-smokers (p less than 0.001). In the sucralfate-treated group the median time to recurrence was 23 weeks among smokers and 32 weeks among non-smokers (p greater than 0.3). Pre-study use of non-steroidal anti-inflammatory drugs and the time to healing of the initial ulcer did not influence the relapse rates in either of the treatment groups.

Abstract
A double-blind, randomized, multicenter study was performed to compare the effect of sucralfate (1 g qid) and cimetidine (400 mg bid) in the treatment of prepyloric ulcer. Altogether 142 patients (68 in the sucralfate and 74 in the cimetidine group) with endoscopically confirmed ulcer within 2 cm of the pylorus completed the study. Endoscopic follow up was performed after four weeks and, if the ulcer was not healed, after eight weeks of treatment. After four weeks, 65% of the ulcers in the sucralfate group were healed, compared to 70% in the cimetidine group. There was no significant difference between sucralfate and cimetidine at either time point. The 95% confidence interval for the difference in ulcer healing with sucralfate or cimetidine ranged from +4 to -19% at eight weeks. Said another way, with an observed difference of 7% (83% vs 90%), the 95% confidence limit ranged from 4% in favor of sucralfate to 19% in favor of cimetidine. Symptomatic relief, antacid intake, and side effects did not differ significantly between the two groups. The healing rate of prepyloric ulcer in this study is similar to that reported for duodenal ulcer after four and eight weeks when treated with sucralfate or cimetidine. Sucralfate is safe and as effective as cimetidine in the short-term treatment of prepyloric ulcer.

Abstract
A double-blind, randomized, multicenter study was performed to compare the effects of sucralfate and cimetidine for the short-term treatment of gastric and prepyloric ulcers. Ulcer healing was evaluated endoscopically at 4-week intervals up to 8 weeks in the PPU study and up to 12 weeks in the GU study. A total of 142 PPU and 134 GU patients completed the study. The overall healing rates after 8 weeks in the PPU study were 83% for the sucralfate group and 90% for the cimetidine group (NS), while the cumulative healing rates after 12 weeks in the GU study were 98% for the sucralfate group and 94% for the cimetidine group (NS). The confidence interval means that the 95% confidence limit ranges from 11% in favour of sucralfate to 2% in favour of cimetidine in the GU study and corresponding figures of 4% 19% in the PPU study. There were significantly more patients in the cimetidine group taking antacid tablets after 3 weeks in the GU study. Symptomatic relief did not differ significantly. Reported side effects and symptoms, pooled together with our duodenal ulcer study, were mostly non-specific and in some part related to the ulcer disease. In conclusion, sucralfate and cimetidine are both excellent healing agents for the short-term treatment of PPU and GU. Both give rapid and good symptomatic relief with no side effects of any importance.

Abstract
The concept of a very limited effective period for prophylactic antibiotic action was challenged in a prospective, controlled and randomized study featuring a simplified method for assessing the degree of contamination in the operative field during colorectal surgery. The 226 patients were given 1 g metronidazole IV on induction of anaesthesia and 12 h postoperatively. Following standardized saline irrigation of the abdominal cavity, a uriculture dipslide was dipped in the residual fluid just before abdominal closure. The dipslide was incubated for 18 h, and colony counts of coliforms and Staphylococcus aureus were made. The number of colony-forming units (CFU) was classified as 0, 1-4 or greater than or equal to 5 (n = 123, 33 and 70). The patients with CFU greater than or equal to 5 were randomized to receive cefuroxime (1.5 g IV/8 h for 2 days) or no more antibiotics. In the patients given only metronidazole, the incidence of postoperative infections rose with the colony counts (5.7, 9.1 and 41.2 per cent with CFU 0, 1-4 and greater than or equal to 5). Addition of cefuroxime reduced the 41.2 per cent infection rate to 8.3 per cent (P = 0.003). The method thus identified a high-risk group in which a short postoperative course of cefuroxime significantly lowered the rate of sepsis.

Abstract
A double blind randomised study was undertaken to compare sucralfate and cimetidine in short term treatment of gastric ulcer. The study included 149 patients with endoscopically confirmed gastric ulcerations. Patients with prepyloric ulcers 2 cm or less from the pyloric ring were not accepted for participation in the trial. Ulcer healing was assessed endoscopically at four week intervals. A total of 134 patients completed the study. The cumulative healing rates after 12 weeks were 98% for sucralfate and 94% for cimetidine treated patients. After four and eight weeks, the healing rates were 61% and 94% for sucralfate and 69% and 94% for the cimetidine-treated group respectively. No statistically significant differences in healing rates were seen. The 95% confidence interval was calculated for the difference between the ulcer healing rates of sucralfate and cimetidine. This interval was found to range between +11% and -2% after 12 weeks of treatment - that is, the healing efficacy of sucralfate was calculated to be at most 11% better or 2% worse than that of cimetidine. No significant differences in symptom relief, side effects or antacid intake were found.

Abstract
A multicenter randomized double-blind study was performed to compare a cytoprotective agent (sucralfate) and an acid-reducing agent (cimetidine) in the treatment of duodenal ulcer. Patients with acute ulcerations in the pyloric ring and duodenal bulb confirmed by endoscopy were included in the trial. All patients were examined after 4 and, if not cured, after 8 weeks. A total of 371 patients from 15 centers completed the trial. The patient groups were comparable. At 8 weeks 86% of 177 patients receiving sucralfate treatment were cured, compared with 92% of 194 receiving cimetidine (NS). The corresponding figures at 4 weeks were 71% (sucralfate) and 77% (cimetidine) (NS). The 95% confidence interval for the difference in ulcer healing efficacy of sucralfate compared with cimetidine at 8 weeks was -12% to +5%. Antacid intake and symptoms decreased rapidly in both groups. Three patients were withdrawn owing to side effects. It is concluded that sucralfate and cimetidine. representing two different approaches to ulcer therapy, are both very effective and compare well with regard to ulcer healing, symptom relief, and side effects in the short-term treatment of acute duodenal ulcer.

Abstract
Thirteen patients with primary hyperparathyroidism were treated for 4-8 weeks with the H2-blocker cimetidine at a daily dose of 1 g. The drug had no effect on the serum concentrations of calcium or parathyroid hormone, nor did any of the patients improve clinically during the period of treatment. The recently reported efficacy of cimetidine in primary hyperparathyroidism is strongly questioned by the present results.

Abstract
Plasma exchange was performed in 2 patients with classical rheumatoid arthritis, complicated in one case by necrotic vasculitis, and in the other by mononeuritis multiplex. Immediate improvement in the peripheral circulation was observed in both patients with subsequent healing of necroses and nerve function, respectively. The treatment was combined with low doses of corticosteroids and cytostatic agents. After 2 years, both patients were still receiving intermittent plasma exchanges, performed at 3-4 month intervals. A correlation between immediate circulatory improvement and lowered plasma viscosity by the plasma exchange was indicated.

Abstract
Elective splenectomies performed in children aged 0-14 during the period 1968 to 1977 have been reviewed. One hundred and twelve children were splenectomized during the period studied. The indication for splenectomy was usually a haematological disorder e.g. hereditary spherocytosis or idiopathic thrombocytopenia. As splenectomized children run the risk of developing overwhelming sepsis, inquiries have been sent to all children. Two cases of nonfatal pneumococcal septicaemia are reported. Although the incidence of septicaemia is low, spleensaving operations are to be preferred where possible. When splenectomy is performed, pneumococcal antibodies should be determined. If a low titre is found, polyvalent pneumococcal vaccine should be used.

Abstract
A previous study of patients with allergic contact dermatitis yielded results which supported the hypothesis that the presence of certain HLA antigens led to a predisposition to allergen-specific reactions and others to multiple contact sensitivity. The present study was performed to test this hypothesis. 129 patients sensitive to one allergen only (either chromium, nickel, formalin or balsam of Peru) and 83 patients sensitive to two or more allergens were HLA typed regarding the A and B loci. A series of 368 persons matched with regard to sex, age and place of residence were used as controls. A tendency towards an association between HLA B7 and contact allergy was observed. No other data confirming the hypothesis mentioned above were obtained. Among 37 patients who also had atopic diathesis a decreased frequency of HLA B7 was found.

Abstract
Plasma calcitonin was determined in 33 patients with breast carcinoma. Eight patients had bone metastases as revealed at scintigraphy and radiography. Only 3 of the 33 patients had elevated plasma calcitonin, 2 had osteolytic bone metastases. It is concluded that the determination of plasma calcitonin is of no value in the evaluation of patients with breast malignancy and it should not be referred to as a tumor marker.

Abstract
Plantar flexion strengths were studied in 30 right-handed males. Static and dynamic maximum plantar flexion torques were recorded, knees fully extended (0 degrees) and in 90 degrees flexion. In five of the subjects the soleus and gastrocnemius muscle structure were studied by light microscopy and enzyme histochemistry. Specimens were obtained by needle biopsy, usually bilaterally. Intraindividual declines of force were found to be a function of angular motion velocity. Static and dynamic torques correlated significantly. Peak torques were significantly greater (mean 15%) at the 0 degrees than at the 90 degrees knee angle and left maximum plantar flexion torques at 0 degrees were greater (mean 10%) than right. Mean morphometric data on the m. soleus suggested right-left symmetry, which could not be demonstrated for the m. gastrocnemius. Fibres with low stainability for myofibrillar ATPase (Type 1 fibres) had smaller diameters, but constituted the major part of the cross-sectional areas. In these five non-athletes no significant correlation between data on plantar flexion strength and morphometric data on triceps surae structure could be demonstrated. On the other hand, strength covariated with calf circumference.

Abstract
82 consecutive patients checked at the out-patient clinic of the Psychiatric Department of the Umeå University were typed for HL-A antigens. The patients belonged to the diagnostic subgroups: bipolar (manic-depressive) psychosis (n = 33), unipolar recurrent depressive psychosis (n = 29) and cycloid psychosis (n = 20) and all had been on lithium treatment for at least 6 months. By comparing the group of those who did not relapse on lithium therapy (n = 48) with the group of those who did relapse (n = 34) there was a significantly higher frequency of the HL-A A3 antigens among those who did relapse, and none of those who did not relapse were found to have the HL-A B18 antigens. The results suggest a possible interference between HL-A antigens and response to lithium treatment. However, a large number of antigens were tested and a small number of patients.

Abstract
HLA antigens were studied in 50 patients, 40 males, 10 females and two brothers of patients, all suffering from schizophrenic syndromes. The average duration of illness for the whole group was 18 +/- 1.5 years. The frequency of A10 antigen was increased in the schizophrenic patients as compared with 449 healthy individuals. None of the findings concerning HLA and schizophrenia reported in the literature could be verified in the present study. Two ill brothers comprised in the study proved to have the same HLA phenotype as their respective ill sibling. So far there is no conclusive evidence for association between any HLA antigen and 'schizophrenia'. Further investigations should be concerned with families and not with single patients.

Abstract
A total of 168 patients with different types of affective disorders were examined with respect to their HLA antigens. The frequency of the A10 antigen was found to be increased in the patients particularly in those with the unipolar type of disease. The frequency of the A1 antigen was decreased among unipolar patients. A decreased frequency of the B7 antigen was found in the total material of patients, and in particular in those with a bipolar type of disease. Our results were in disagreement with findings by other investigators. So far there is no conclusive evidence for association between any HLA antigen and affective disorders.
