Civil defence in the United Kingdom

What must be avoided in the nuclear age is wishful thinking. Wishful thinking occurs in an atmosphere of maximum terror (as in Mutual Assured Destruction), and where there is little opportunity for reality testing (as in the East‐West communication barrier). In the small, densely populated island of Britain, the size of today's growing nuclear threat will create responses where delusional thinking can easily dominate. A belief in effective civil defence may induce a sense of false security which may in turn direct attention from the fundamental problem of East‐West mistrust.     

Global thinking,local action

This article examines the risk of proliferation of nuclear weapons to several Third World countries, exemplified by recent events in Iraq, and the possibility of rapid acquisition of a nuclear weapons capability in developed countries. It considers the role of the International Atomic Energy Agency and the United Nations in preventing proliferation and calls for wider powers for the latter. The role of the civil nuclear power industry and of reprocessing of nuclear fuel to produce plutonium is stressed, with emphasis on the part played by nuclear power in Japan and the THORP reprocessing plant at Sellafield.     

Cough Frequency in a Group of Males

An epidemiologic study by questionnaire was undertaken in Great Britain and the United States, to provide data on diabetes mellitus in Down’s syndrome. Among 20,362 patients with Down’s syndrome, 88 living diabetics were found.

A high prevalence of diabetes in the population with Down’s syndrome, particularly In the younger age groups, was noted. In these age groups the prevalence of diabetes in the population with Down’s syndrome exceeded that of the general population by factors 6.8, 3.3, and 3.0. Insufficient data exist to determine the exact statistical significance of these ratios. Further investigation is necessary. Nevertheless, a definitive association between Down’s Syndrome and diabetes mellitus is suggested. The role of prediabetes, autoimmunity and genetics in this association is discussed.     

Intravenous lidocaine does not reduce length of hospital stay following abdominal hysterectomy

Purpose

Intravenous lidocaine given both intraoperatively and postoperatively decreases pain scores, reduces opioid consumption, and promotes faster return of bowel function following abdominal surgery. The purpose of this trial was to determine if intravenous lidocaine limited to the intraoperative period reduces length of hospital stay and improves functional recovery following abdominal hysterectomy.

Methods

Following Research Ethics Board approval and informed consent, women of American Society of Anesthesiologists’ class I and II undergoing abdominal hysterectomy were assigned randomly to lidocaine and control groups. Lidocaine subjects received an intravenous bolus of 1.5 mg·kg^?1 followed by an infusion of 3 mg·kg^?1·hr^?1, while control subjects received matching placebo. Patients, anesthesiologists, and study personnel were blinded, and anesthesia and multimodal perioperative analgesia were standardized. The primary outcome of this trial was discharge from hospital on or before the second postoperative day (POD2). Additional criteria were assessed for secondary outcomes, i.e., discharge fitness on POD2, length of hospital stay, opioid use, numeric rating scores for pain, quality of recovery, and recovery of bowel function.

Results

Ninety of the 93 women who were recruited completed the study protocol. The characteristics of the patients in both groups were similar—lidocaine group (n = 44) and control group (n = 46)—and no difference was noted between groups in the numbers of women discharged from hospital on POD2 (10 lidocaine, 15 control; P = 0.295). Days to discharge fitness (P = 0.666) and length of hospital stay (P = 0.456) were also similar. Differences in opioid consumption, pain scores, and recovery were neither clinically nor statistically significant.

Conclusion

Intraoperative administration of intravenous lidocaine did not reduce hospital stay or improve objective measures of analgesia and recovery following abdominal hysterectomy. This trial was registered at ClinicalTrials.gov (NCT00382499).     

Revisiting Traditional Risk Factors for Rejection and Graft Loss After Kidney Transplantation

Single‐antigen bead (SAB) testing permits reassessment of immunologic risk for kidney transplantation. Traditionally, high panel reactive antibody (PRA), retransplant and deceased donor (DD) grafts have been associated with increased risk. We hypothesized that this risk was likely mediated by (unrecognized) donor‐specific antibody (DSA). We grouped 587 kidney transplants using clinical history and single‐antigen bead (SAB) testing of day of transplant serum as (1) unsensitized; PRA = 0 (n = 178), (2) third‐party sensitized; no DSA (n = 363) or (3) donor sensitized; with DSA (n = 46), and studied rejection rates, death‐censored graft survival (DCGS) and risk factors for rejection. Antibody‐mediated rejection (AMR) rates were increased with DSA (p < 0.0001), but not with panel reactive antibody (PRA) in the absence of DSA. Cell‐mediated rejection (CMR) rates were increased with DSA (p < 0.005); with a trend to increased rates when PRA>0 in the absence of DSA (p = 0.08). Multivariate analyses showed risk factors for AMR were DSA, worse HLA matching, and female gender; for CMR: DSA, PRA>0 and worse HLA matching. AMR and CMR were associated with decreased DCGS. The presence of DSA is an important predictor of rejection risk, in contrast to traditional risk factors. Further development of immunosuppressive protocols will be facilitated by stratification of rejection risk by donor sensitization.
