Second‐look endoscopy with thermal coagulation or injections for peptic ulcer bleeding: A meta‐analysis

Background and Aims: In the management of peptic ulcer bleeding, the benefits of second‐look endoscopic treatment with thermal coagulation or injections in controlling recurrent bleeding is unsure. This study set out to compare efficacy of routine second‐look endoscopy with treatment using either thermal coagulation or injections versus single endoscopy by pooling data from published work. Methods: Full publications in the English‐language published work as well as abstracts in major international conferences were searched over the past 10 years, and six trials fulfilling the search criteria were found. Outcome measurements included: (i) recurrent bleeding; (ii) requirement of surgical intervention; and (iii) mortality. We examined heterogeneity of trials and pooled the effects by meta‐analysis. The quality of studies was graded according to the prospective randomization, methods of patient allocation, the list of exclusion criteria, outcome definitions and the predefined salvage procedures for uncontrolled bleeding. Results: Among 998 patients recruited in these five randomized trials, 119 received routine second‐look endoscopy with thermal coagulation, and 374 received second‐look with endoscopic injection and 505 had single endoscopic therapy. Less recurrent bleeding was reported after thermal coagulation (4.2%) than single endoscopy (15.7%) (relative risk [RR] = 0.29; 95% confidence interval [CI] = 0.11–0.73), but no reduction was reported for the requirement of surgical intervention and all‐cause mortality. Injection therapy did not reduce re‐bleeding (17.6%) when compared to single endoscopy (20.8%; RR = 0.85; 95% CI = 0.63–1.14), requirement for surgery and mortality. Conclusion: Routine second‐look endoscopy with thermal coagulation, but not injection therapy, reduced recurrent peptic ulcer bleeding. There is no proven benefit in reducing surgical intervention and overall mortality.     

Hepatic derangement following N‐Acetylcysteine enemas in an infant with cystic fibrosis

We discuss an infant with MI secondary to cystic fibrosis, who was managed surgically by a double barrel ileostomy for mid – small bowel atresia and developed severe faecal impaction in the post – operative period. The faecal impaction was treated successfully with oral NAC and 0.2% NAC contrast enemas. The patient's liver function tests revealed a dramatic increase in transaminases and bilirubin contemporaneous with the administration of the enemas. The levels showed a spontaneous improvement after discontinuation. This is only the second reported case of hepatotoxicity secondary to NAC enemas in the literature. While our experience offers modest support for the use of NAC, its efficacy is not yet proven and paediatric surgeons using NAC in the enema form need to closely monitor liver function contemporaneous with this agent's administration and adjust their treatment accordingly.     

Urinary albumin excretion rate and puberty in non-diabetic children and adolescents

Slightly elevated urinary albumin excretion rate (microalbuminuria) is a marker of early diabetic nephropathy, but it is unclear if the established definition of microalbuminuria (20–200 μg/min) is correct for children and adolescents. We investigated the albumin excretion rate, albumin/creatinine ratio and urinary albumin concentration in 150 healthy schoolchildren and adolescents to (a) obtain a reference value for albumin excretion rate, (b) relate albumin excretion to pubertal stages and (c) evaluate albumin/creatinine ratio and morning albumin concentration as screening methods for elevatcd albumin excretion rate. Albumin concentration was measured by immunoturbidimetry in timed overnight urine samples. The albumin excretion showed a skewed distribution (geometric mean 3.2 μg/min, 95 percentile 15.1 μg/min). In girls, a peak in the albumin excretion rate was found at the pubertal stage 4 (Tanner) and in boys at stage 5. Albumin/creatinine ratio of 2.5 mg/mmol as a scrccning level for elevatcd albumin cxcrction (15 μg/min) showed a high positivc (0.88) and negative (0.99) predictive value.     

Aging: a body of resistance

The present paper explores the language of aging used, often unthinkingly, by nurses and policy makers. Terms so often used when describing aging, such as "frailty" and "dependence", are used in a way that implies a common knowledge, a point of convergence. It will be argued, using data gathered from research, that these terms often are a point of departure and that they may not signify a common understanding at all. From a postmodern perspective, it will be argued that it is at this point that common knowledge comes up against corporeal or embodied knowledge. In conclusion, the author will argue for a clinical encounter in which intersubjective meanings can be elucidated.

Interpeduncular fossa sign: CT criterion of subarachnoid hemorrhage

A retrospective study of 100 cerebral computed tomography scans interpreted as displaying subarachnoid hemorrhage was undertaken to determine the frequency of blood in the interpeduncular fossa as a useful radiographic sign. The results indicate that the interpeduncular fossa sign is second only to blood in the Sylvian fissure-circular sulcus area as a reliable indicator of subarachnoid hemorrhage on CT scans.
