RESUMEN

Fire or combustion occurring during laparotomy is an uncommon and potentially hazardous event that can be precipitated by the use of surgical energy devices in the presence of enteric gases or exogenous materials present in the abdomen such as alcohol. Oxygen necessary for a combustive event can be increased in the setting of a proximal enteric injury and with higher concentrations of inspired oxygen during anaesthesia. We report on a case of combustion on entry to the abdomen using monopolar diathermy during exploratory laparotomy for gastric antral perforation in the presence of alcohol and enteric gases.

RESUMEN

INTRODUCTION: Acute mesenteric venous thrombosis is a rare but potentially fatal condition with superior mesenteric vein being the most common site of thrombosis development [1]. It is more common in patients with underlying disorders which cause disruptions to Virchow's Triad of hypercoagulability, stasis and endothelial injury. The disease is often associated with intestinal ischemia in its acute form, further complicating its management. PRESENTATION OF CASE: We present a case of acute superior mesenteric venous thrombosis resulting in jejunal ischemia in a 60-year-old Caucasian male with possible ulcerative colitis. A computed tomography (CT) scan demonstrated features of intestinal infarction. However, the patient was stable after initial resuscitation with a non-peritonitic abdomen and was subsequently managed with conservative measures. DISCUSSION: We have illustrated a case of a patient with acute mesenteric venous thrombosis with potential bowel compromise. Despite concerning CT features, the patient was clinically stable and responded to conservative management. We hope to emphasise that although radiology plays a crucial role in modern medicine, it is important to make therapeutic decisions based on clinical findings. CONCLUSION: Acute mesenteric venous thrombosis is a complex entity. It requires a multidisciplinary team approach to plan for the most appropriate treatment strategy suitable for each patient as all options are associated with significant risks. The underlying cause should be established as this will determine any long-term management necessary to prevent recurrence.

RESUMEN

OBJECTIVES: Determine whether words contained in unsolicited patient complaints differentiate physicians with and without neurocognitive disorders (NCD). METHODS: We conducted a nested case-control study using data from 144 healthcare organizations that participate in the Patient Advocacy Reporting System program. Cases (physicians with probable or possible NCD) and two comparison groups of 60 physicians each (matched for age/sex and site/number of unsolicited patient complaints) were identified from 33,814 physicians practicing at study sites. We compared the frequency of words in patient complaints related to an NCD diagnostic domain between cases and our two comparison groups. RESULTS: Individual words were all statistically more likely to appear in patient complaints for cases (73% of cases had at least one such word) compared to age/sex matched (8%, p < 0.001 using Pearson's χ2 test, χ2 = 30.21, df = 1) and site/complaint matched comparisons (18%, p < 0.001 using Pearson's χ2 test, χ2 = 17.51, df = 1). Cases were significantly more likely to have at least one complaint with any word describing NCD than the two comparison groups combined (conditional logistic model adjusted odds ratio 20.0 [95% confidence interval 4.9-81.7]). CONCLUSIONS: Analysis of words in unsolicited patient complaints found that descriptions of interactions with physicians with NCD were significantly more likely to include words from one of the diagnostic domains for NCD than were two different comparison groups. Further research is needed to understand whether patients might provide information for healthcare organizations interested in identifying professionals with evidence of cognitive impairment.

RESUMEN

BACKGROUND: Despite increasing efforts in perioperative management, postoperative iron deficiency anaemia persists, and few data are available about the management of this condition. In this study, we aimed to determine whether giving postoperative intravenous iron (in the form of ferric carboxymaltose) improved iron stores, haemoglobin concentrations, and outcomes following surgery. METHODS: We did a prospective, open-label, randomised, controlled study of patients at two centres (a general hospital and a private health-care centre) in Tasmania, Australia, undergoing elective surgery with functional iron deficiency anaemia (haemoglobin 70-120 g/L and ferritin ≤100 µg/L or iron saturation ≤20%), measured at day 1 postoperatively. Consecutive routine elective surgical patients who were having major orthopaedic surgery, abdominal, and genitourinary surgery, and other surgeries were recruited. Via computer-generated randomisation, patients were randomly assigned (1:1) to either a single dose of intravenous 1000 mg ferric carboxymaltose (intervention group) or standard care, consisting of observation (control group). The primary endpoints were changes in haemoglobin concentrations and iron stores at 4 weeks postoperatively, and the number of transfused units of blood required postoperatively until discharge. Analyses were done on an intention-to-treat basis. This trial is registered with the Australian New Zealand Clinical Trials Registry and the WHO International Clinical Trials Registry platform (number ACTRN12614001261606). FINDINGS: Between Dec 17, 2014, and May 7, 2015, we recruited 201 eligible patients, assigning 103 to intravenous ferric carboxymaltose and 98 to standard care only. Baseline mean haemoglobin was 105·5 g/L (SD 13·8) in the standard care group versus 106·2 g/L (11·9) in the ferric carboxymaltose group, improving at 4 weeks to 121·5 g/L (SD 14·5) in the standard group and 130·1 g/L (11·3) in the ferric carboxymaltose group (mean difference of 7·84 g/L, 95% CI 3·79-11·9; p<0·0001 in favour of the ferric carboxymaltose group). Significant improvements in serum iron (5·36 µmol/L, 95% CI 3·62-7·09; p<0·0001), iron saturation (11·40%, 95% CI 8·33-14·50; p<0·0001), and serum ferritin concentrations (468 µg/L, 95% CI 355-582; p<0·0001) were also noted in the ferric carboxymaltose group at 4 weeks compared with standard care, although no differences were noted in transferrin concentrations (0·06 g/L, 95% CI -0·97 to 1·09; p=0·62). Fewer transfused blood units were given in the ferric carboxymaltose group (to one of 103 patients [<1%]) than in the standard care group (to five of 98 patients [5%]; incidence rate ratio 0·10; 95% CI 0·01-0·85; p=0·035). No adverse events were observed with ferric carboxymaltose treatment. INTERPRETATION: Postoperative intravenous ferric carboxymaltose is a feasible and pragmatic management approach in surgical patients with functional iron deficiency anaemia. Our study suggests that patient blood management guidelines should be updated, incorporating the use of postoperative intravenous iron infusion to optimise patient outcomes. Further trials to assess our approach are warranted. FUNDING: Launceston General Hospital, Launceston, TAS, Australia, in affiliation with the University of Tasmania, TAS, Australia.
