We performed a 1-year study to determine whether intermittent short courses of the microemulsion formulation of cyclosporin (Neoral) could effectively control plaque psoriasis and whether tapering or abrupt cessation of cyclosporin therapy would influence time to relapse. Four hundred patients with plaque psoriasis were included in this open, multicentre, randomized study. All patients commenced cyclosporin at a dose of 2.5 mg/kg daily. Cyclosporin dosage could be increased to a maximum of 5 mg/kg daily. Treatment was continued until clearance of psoriasis or for a maximum of 12 weeks. Patients were then randomly assigned either to stop cyclosporin abruptly or to have the dose reduced by 1 mg/kg daily each week until cessation. On relapse, patients were given another course of cyclosporin. Patients were followed for at least 1 year, during which they could receive as many treatment courses as necessary. The number of patients who required one, two, three and four treatment courses was 400, 259, 117 and 26, respectively. The median time to relapse after the end of the first treatment period was 109 days in the group of patients randomized to stop cyclosporin abruptly and 113 days in patients randomized to taper off cyclosporin (P = 0.038). More than 30% of patients had not relapsed 6 months after having stopped treatment. After each treatment course, the Kaplan-Meier probability of achieving 75% or more reduction in disease area by day 84 of treatment was 83%, 76%, 73% and 66%, respectively. Mean serum creatinine concentration and blood pressure did not show any clinically significant changes over time. Our results show that intermittent short-course therapy with Neoral, when used in conjunction with topical therapy, is well tolerated and provides effective control of plaque psoriasis for 1 year. Tapering off cyclosporin on treatment cessation induces a slight delay in psoriasis relapse.
A 5-year prospective study was performed to monitor liver function tests (LFTs) in patients receiving total parenteral nutrition (TPN). A gradual and progressive rise was seen in the plasma concentration of bilirubin, aspartate transaminase, and alkaline phosphatase. The rate of rise was not increased in patients with LFT abnormalities before the start of TPN. Half of the patients had an episode of sepsis during TPN, but overall abnormal LFTs did not appear more common in these patients than in those without obvious sepsis. Patients with malignant disease, those requiring long-term TPN, and those requiring a nonstandard TPN regimen were more likely to develop raised LFTs.
Evidence exists to suggest a detrimental effect of blood transfusion on survival after resection for malignant disease. Immune suppression due to transfusion has been implicated, though this remains unproven. We have conducted a retrospective study of 69 patients (38 transfused, 31 not transfused) with squamous carcinoma of the larynx to assess the effect of blood transfusion on survival after laryngectomy. Patients were compared for age, sex, smoking habit, tumour site and stage, grade of operating surgeon, preoperative haemoglobin, tumour nucleolar organizer region status, and operation time. The minimum follow-up was 5 years. In the transfused group 21/38 died as a result of their malignant disease and only 4/31 in the untransfused group. This difference was highly significant (P less than 0.001, chi-squared test) and using a multivariate analysis the only variable associated with a decreased survival time was whether a blood transfusion had been received. We conclude that peri-operative blood transfusion is associated with decreased survival after laryngectomy. However, whether this association is causal remains unproven.
Summary
A case of small bowel obstruction caused by an enterolith from a jejunal diverticulum is reported. As such diverticula are usually asymptomatic, the diagnosis was not entertained pre-operatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
