Mortality in the surgical intensive care unit (SICU) and hospital was significantly different across the age groups and rose with age. However, the modest 11.1 per cent SICU mortality rate in centenarians along with their length of stay (LOS) statistics indicate that these patients fare relatively well in surgical intensive care.

We conclude that there was no symptomatic hypoglycemia, and glucose profiles returned to a similar baseline level in those whose TPN was abruptly stopped when compared with those in the tapered group. These data demonstrate that patients receiving TPN can have parenteral nutrition abruptly stopped without the development of significant hypoglycemia.

Overall perioperative mortality was 9.4 per cent (3 of 32). Twenty-two surgeries (69%) were performed on an emergency basis, and all three deaths were in this group (13.6%). Overall morbidity rate was 57 per cent. Mean intensive care unit stay was 4.8 days. Most patients were discharged home. Our findings support the perioperative safety of elective general surgery in nonagenarians (0% mortality and 20% morbidity). We also found an acceptable risk (13.6% mortality and 68% morbidity) for emergency procedures despite significant comorbid conditions. Most of the patients had acceptable functional outcomes.

Regional anesthesia required lower doses of antihypertensive medication in the early postoperative period when compared with general anesthesia. The doses of vasoactive medications used had no significant impact on the complication rate. Regional anesthesia allowed for shorter stay in both the intensive care unit and total hospital stay.

CONCLUSIONS: Patient survival of in vivo split liver transplantation (SLT). is not significantly different from that of whole-organ orthotopic liver transplantation. The variables affecting outcome of in vivo SLT are similar to those in whole-organ transplantation. in vivo SLT should be widely applied to expand a severely depleted donor pool.

ABSTRACT: SUMMARY BACKGROUND DATA: Ischemic preconditioning is a short period of ischemia followed by a brief period of reperfusion before a sustained ischemic insult.<snip> CONCLUSIONS: Ischemic preconditioning is a simple and effective modality protecting the liver against subsequent prolonged periods of ischemia. This strategy may be a more attractive technique than intermittent inflow occlusion, which is associated with increased blood loss during each period of reperfusion.

There was an improvement in pain relief in the intrathecal morphine group, with significantly lower median VAS pain scores on movement at 4 h (0 (median 0-1.5) vs 5 (1.25-7.75) P < 0.01), 12 h (2 (1-5) vs 6 (3-8) P < 0.01) and 24 h (3 (1-5) vs 5 (3-7) P < 0.05) postoperatively, despite using significantly less patient-controlled morphine (20 mg (10.25-26.25) vs 38.5 mg (27-51) P < 0.01) in the first 24 h. Although marked disturbances in respiratory pattern were observed in both groups, none of the patients in the study had severe hypoxaemia (SpO2 < 85% > 6 min h-1) and there was no significant difference in the incidence of mild (SpO2 < 94% > 12 min h-1) or moderate (SpO2 < 90% > 12 min h-1) hypoxaemia or in the incidence of episodes of apnoea or hypopnoea in the two groups.

ABSTRACT: Location of the tip of a central venous catheter (CVC) within the pericardium has been associated with potentially lethal cardiac tamponade. Because the pericardium cannot be seen on chest x-ray (CXR), an alternative radiographic marker is needed for correct placement of CVCs. The anatomy of the region was studied in 34 cadavers. The carina was a mean (SEM) distance of 0.4 (0.1) cm above the pericardial sac as it transverses the superior vena cava (SVC). In no case was the carina located below the pericardial sac. The carina is a reliable, simple anatomical landmark for the correct placement of CVCs. In almost all cases, the carina is radiologically visible even in poor quality, portable CXRs. CVC tips should be located in the SVC above the level of the carina in order to avoid cardiac tamponade.

CONCLUSIONS-Prolonged CPR is frequently associated with increases of Prostate-specific antigen (PSA), acid phosphatase (AP), and prostatic acid phosphatase (PAP)serum levels. Therefore, PSA cannot be used for diagnosis of adenocarcinoma of the prostate during the first weeks after CPR. Further evaluation of these parameters as additional prognostic markers after CPR is warranted.

CONCLUSIONS: The present study demonstrates that during long-term therapy, carvedilol improves cardiac performance to a greater extent than metoprolol when administered to patients with heart failure in the doses shown to be effective in clinical trials. These differences were likely related to a greater antiadrenergic activity of carvedilol.

ABSTRACT: BACKGROUND: The quantity and intensity of physical activity required for the primary prevention of coronary heart disease (CHD) remain unclear. Therefore, we examined the association of the quantity and intensity of physical activity with CHD risk and the impact of other coronary risk factors. METHODS AND RESULTS: We followed 12 516 middle-aged and older men (mean age 57.7 years, range 39 to 88 years) from 1977 through 1993. Physical activity was assessed at baseline in kilojoules per week (4.2 kJ=1 kcal) from blocks walked, flights climbed, and participation in sports or recreational activities. During follow-up, 2,135 cases of incident CHD, including myocardial infarction, angina pectoris, revascularization, and coronary death, occurred. Compared with men expending <2,100 kJ/wk, men expending 2,100 to 4,199, 4,200 to 8,399, 8,400 to 12,599, and >/=12,600 kJ/wk had multivariate relative risks of 0.90, 0.81, 0.80, and 0.81, respectively (P: for trend=0.003). When we considered the independent effects of specific physical activity components, only total sports or recreational activities (P: for trend=0.042) and vigorous activities (P: for trend=0.02) were inversely associated with the risk of CHD. These associations did not differ within subgroups of men defined by coronary risk factors. Finally, among men with multiple coronary risk factors, those expending >/=4,200 kJ/wk had reduced CHD risk compared with men expending <4,200 kJ/wk. CONCLUSIONS: Total physical activity and vigorous activities showed the strongest reductions in CHD risk. Moderate and light activities, which may be less precisely measured, showed nonsignificant inverse associations. The association between physical activity and a reduced risk of CHD also extends to men with multiple coronary risk factors.

CONCLUSIONS: These data clearly indicate that physical activity is associated with decreased coronary heart disease (CHD) risk. Furthermore, they lend some support to recent recommendations that allow for the accumulation of shorter sessions of physical activity, as opposed to requiring 1 longer, continuous session of exercise. This may provide some impetus for those sedentary to become more active.

CONCLUSIONS: Intra-abdominal hypertension (IAH) occurs commonly in major burn patients, and abdominal compartment syndrome (ACS) is seen regularly in patients with more than 70% body surface area burns. We recommend bladder pressure measurements after infusion of more than 0.25 L/kg during the acute resuscitation phase and for peak inspiratory pressures greater than 40 cm H2O. Whereas ACS warrants surgical decompression of the abdominal cavity, IAH usually responds to conservative therapy.

ABSTRACT: BACKGROUND: Causalgia is a rare disease in civilian practice, and most reports regarding causalgia in the literature are from major extended wars. To increase awareness of this syndrome, our wartime experience with this disease is presented. CONCLUSION: Causalgia is essentially a war casualty disease. The condition is associated with burning pain, hyperesthesia, and symptoms of sympathetic overactivity. Sympathectomy is effective and the treatment of choice, particularly for patients who respond temporarily to sympathetic blocks.
MB: Why does it occur mainly in military medicine.

CONCLUSION: Children treated at PTC or ATC AQ have significantly better outcome compared with those treated at ATC. Severely injured children (Injury Severity Score > 15) with head, spleen, or liver injuries had the best overall outcome when treated at PTC. This difference in outcome may be attributable to the approach to operative and nonoperative management of head, liver, and spleen injuries at PTC.

ABSTRACT: An urgent blood drive in which active duty military field surgical hospital personnel volunteered to donate whole blood was conducted, and administration of warm, whole blood prevented the exsanguination of a normothermic coagulopathic patient who had received a massive transfusion. In austere care settings in which full blood banking capability may not be available, physicians should consider that exsanguinating hemorrhage can potentially be controlled surgically, but nonsurgical bleeding requires specific replacement therapy, and whole blood may be the best selection for repleting deficiencies of components that are otherwise unavailable.

RESULTS: The incidence of deep prevent venous thromboembolism (VT) and pulmonary embolism reported in different studies varies widely. The pooled rates are 11.8% for deep venous thrombosis and 1.5% for pulmonary embolism. Only a few randomized controlled trials have evaluated the methods of VT prophylaxis among trauma patients, and combining their data is difficult because of different designs and preventive methods used. The quality of most studies is low. Meta-analysis shows no evidence that low-dose heparin, mechanical prophylaxis, or low-molecular-weight heparin are more effective than no prophylaxis or each other. However, the 95% confidence intervals of many of the comparisons are wide; therefore, a clinically important difference may exist. CONCLUSION: The trauma literature on prevent venous thromboembolism (VT) prophylaxis provides inconsistent data. There is no evidence that any existing method of VT prophylaxis is clearly superior to the other methods or even to no prophylaxis. Our results cast serious doubt on the existing policies on VT prophylaxis, and we call for a large, high-quality, multicenter trial that can provide definitive answers.
MB: How depressing!

CONCLUSION: Spinal injuries, spinal cord injuries, and age are risk factors for development of deep venous thrombosis (DVT). Prophylactic placement of vena caval filters (VCF) in selected trauma patients may decrease the incidence of pulmonary embolism. Future research with well-designed studies is required to provide definitive answers.

ABSTRACT: OBJECTIVES: A recent review of problem-based learning's effect on knowledge and clinical skills updated findings reported in 1993. The author argues that effect sizes (ES) seen with PBL have not lived up to expectations (0.8-1.0) and the theoretical basis for PBL, contextual learning theory, is weak. RESULTS: Effect sizes of 0.8-1.0 would require some students to move from the bottom quartile to the top half of the class or more. The average ES reported in the literature was 0.50 and many commonly used and accepted medical procedures and therapies are based upon studies with ESs below 0.50. CONCLUSIONS: Effect sizes of 0.8-1.0 are an unreasonable expectation from PBL because, firstly, the degree of changes that would be required of individuals would be excessive, secondly, leading up to medical school, students are groomed and selected for success in a traditional curriculum, expecting them to do better in a PBL curriculum than a traditional curriculum is an unreasonable expectation, and, thirdly, the average study reported in the literature and many commonly used and accepted medical procedures and therapies are based upon studies having lesser ESs. Information-processing theory, Cooperative learning, Self-determination theory and Control theory are suggested as providing better theoretical support for PBL than Contextual learning theory. Even if knowledge acquisition and clinical skills are not improved by PBL, the enhanced work environment for students and faculty that has been consistently found with PBL is a worthwhile goal.
MB: Sounds as though the exercise has been a waste of time, effort and money.

ABSTRACT: CONTEXT: Research on the factors affecting progress in medical schools has typically focused on mainstream (non-Indigenous Australian, non-international) students in traditional, didactic programmes. These results may not be applicable to students, particularly those from culturally diverse backgrounds, undertaking problem-based learning courses. OBJECTIVE: This study used qualitative methodology to explore and compare factors affecting progress for mainstream Australian students (non-Indigenous Australian, non-international) and international students (full fee-paying students who had relocated countries to study) in a problem-based learning medical course. Intervention strategies were devised on the basis of the participants' experiences. METHODS: Six focus group discussions were conducted (three with mainstream Australian and three with international participants). Transcripts of these discussions were coded and analysed independently by two researchers and discussed until consensus was attained. RESULTS: Participants identified both positive and negative experiences related to the course structure, which were consistent with previous findings. The participants' experiences demonstrated a relationship between sense of 'belongingness' to the medical school community, participation in learning opportunities and progress through the course. CONCLUSIONS: The results suggest that interventions aimed at reducing barriers to progress need to promote students' confidence, motivation and subsequent participation in course learning opportunities. These results have application to other problem-based learning courses particularly those which face the challenge of providing an optimal learning environment for students from diverse backgrounds.
MB: This sounds pretty holeless too.

RESULTS: 258 people enrolled in the program, and 118 had complete data for two years of treatment. In these 118, blood pressures fell significantly, while ACR and GFR stabilised. Rates of the combined endpoints of renal failure and natural death per 100 person-years were 2.9 for the treatment group (95% CI, 1.7-4.6) and 4.8 for the control group (95% CI, 3.3-7.0). After adjustment for baseline ACR category, the relative risk of the treatment group versus the control group for these combined endpoints was 0.47 (95% CI, 0.25-0.86; P = 0.013). Treatment benefit was especially marked in people with overt albuminuria or hypertension and in non-diabetic people. The estimates of benefit were supported by a fall in community rates of death and renal failure. CONCLUSIONS: Aboriginal people can participate enthusiastically in chronic disease management, with rapid, dramatic improvement in clinical profiles and mortality. Similar programs should be introduced urgently into other Aboriginal communities nationwide.

ARTICLE TITLE: Should there be more teaching of critical thinking in Australian general practice?

ABSTRACT: For clinicians such as GPs, critical thinking includes critical appraisal of scientific evidence and the context of their clinical practice, and critical introspection. Largely due to a lack of rigorous research, there is no evidence that teaching critical thinking or appraisal, at undergraduate or postgraduate levels, improves GPs' clinical performance or their patients' health. Before conducting such research, a systematic review of the available literature (largely in education and psychology) is warranted to assess the efficacy of teaching critical thinking in non-medical environments. Critical thinking is being taught in Australian medical schools and will be introduced in the RACGP Training Program. However, it will be a while before this will have an impact in GPs' surgeries. The challenge will be to design an attractive CME program relevant to GPs while simultaneously evaluating its efficacy.
MB: They say you need a 'built in crap detector'. This probably should be applied to attempts at producing this in students.

ABSTRACT: OBJECTIVE: To examine the relationship between alcohol intake and survival in elderly people. DESIGN AND SETTING: A prospective study over 116 months of non-institutionalised subjects living in Dubbo, a rural town (population, 34,000) in New South Wales. PARTICIPANTS: 1235 men and 1570 women aged 60 years and over who were first examined in 1988-89. MAIN OUTCOME MEASURES: All-causes mortality; gross cost of alcohol per life-year gained. RESULTS: Death occurred in 450 men and 392 women. Intake of alcohol was generally moderate (i.e., less than 14 drinks/week). Any intake of alcohol was associated with reduced mortality in men up to 75 years and in women over 64 years. In a proportional hazards model, the hazard ratio for mortality in men taking any alcohol was 0.63 (95% CI, 0.47-0.84) and in women was 0.75 (95% CI, 0.60-0.94). Cardiovascular deaths in men were reduced from 20/100 (95% CI, 14-26) to 11/100 (95% CI, 9-13) and in women from 16/100 (95% CI, 13-19) to 8/100 (95% CI, 6-10). The reduction in mortality occurred in men and women taking only 1-7 drinks/week--hazard ratios, 0.68 (95% CI, 0.49-0.94) and 0.78 (95% CI, 0.61-0.99), respectively, with a similar protective effect from intake of beer or other forms of alcohol. After almost 10 years' follow-up, men taking any alcohol lived on average 7.6 months longer, and women on average 2.7 months longer, compared with non-drinkers. The gross cost for alcohol per life-year gained if consuming 1-7 drinks/week was $5700 in men, and $19,000 in women. CONCLUSIONS: Moderate alcohol intake in the elderly appears to be associated with significantly longer survival in men 60-74 years and in all elderly women.

.Moderate to severe attacks of MS are best treated with intravenous infusions of high-dose methylprednisolone. Interferon beta reduces the frequency of attacks and the progression of disability in relapsing-remitting MS. Symptomatic therapy is important in the management of spasticity, pain, urinary problems and the other symptoms or complications of MS.

The most compelling published data are in unstable angina and non-Q-wave myocardial infarction (MI). LMWHs are at least as effective as unfractionated heparin in terms of the composite endpoint of death and MI. Conclusive benefits of LMWH use to prevent restenosis after stent insertion or percutaneous transluminal coronary angioplasty have not been established. The data in MI and atrial fibrillation are still preliminary, but encouraging.
