Risk factors, microbiological findings and outcomes of necrotizing fasciitis in New Zealand: a retrospective chart review

Background
The incidence and mortality from necrotizing fasciitis (NF) are increasing in New Zealand (NZ). Triggered by a media report that traditional Samoan tattooing was causing NF, we conducted a chart review to investigate the role of this and other predisposing and precipitating factors and to document NF microbiology, complications and interventions in NZ.

Methods
We conducted a retrospective review of 299 hospital charts of patients discharged with NF diagnosis codes in eight hospitals in NZ between 2000 and 2006. We documented and compared by ethnicity the prevalence of predisposing and precipitating conditions, bacteria isolated, complications and interventions used.

Results
Out of 299 charts, 247 fulfilled the case definition. NF was most common in elderly males. Diabetes was the most frequent co-morbid condition, followed by obesity. Nearly a quarter of patients were taking non-steroidal anti-inflammatory drugs (NSAID). Traditional Samoan tattooing was an uncommon cause. Streptococcus pyogenes and Staphylococcus aureus were the two commonly isolated bacteria. Methicillin-resistant Staphylococcus aureus was implicated in a relatively small number of cases. Shock, renal failure, coagulation abnormality and multi-organ dysfunction were common complications. More than 90% of patients underwent surgical debridement, 56% were admitted to an intensive care unit (ICU) and slightly less than half of all patients had blood product transfusion. One in six NF cases had amputations and 23.5% died.

Conclusion
This chart review found that the highest proportion of NF cases was elderly males with co-morbidities, particularly diabetes and obesity. Tattooing was an uncommon precipitating event. The role of NSAID needs further exploration. NF is a serious disease with severe complications, high case fatality and considerable use of health care resources.

Ethically defensible decision-making in health care: challenges to traditional practice

The concept of paternalism is deeply entrenched in health care. Decision-making about health care can be extremely difficult at times, and many competing interests may influence the outcomes. However, ethically defensible practice aligns itself with acknowledging the patient's prima facie right to be treated as an autonomous individual. This includes the patient's right to make informed decisions or to decide that other(s), such as the close family, should make decisions on his or her behalf. (author abstract)

Euthanasia and assisted suicide : a liberal approach versus the traditional moral view

Within the context of the debate over the recent suspended sentence given to John Stuart Godfrey by Underwood J in the Supreme Court of Tasmania for assisting his elderly mother with her suicide, this article examines some of the more popular arguments for and against the moral acceptability of euthanasia and assisted suicide. This article considers the arguments put forward on the “difference principle” by Rachels and Nesbitt before critically examining the liberal approach to the euthanasia issue as proposed by Kuhse. It is argued that whilst Kuhse is correct to reject the difference principle, she does so for the wrong reasons. The penultimate section of the article provides an overview of the traditional moral view against killing. The final part assesses whether the arguments put forward by proponents of the liberal approach are capable of overcoming this view.

Ranah minang: the changing conception of a traditional minangkabau homeland

The Minangkabau people of West Sumatra, Indonesia, view the physical world as having two distinct components, Ranah Minang (which is itself further divided) and the rantau. Ranah Minang is the traditional, ancient homeland of the group, while the rantau is everything beyond the boundaries of their ancestral lands. This distinction is institutionalised in the folklore of the group and serves as a characterizing dichotomy in their worldview. Even today, when the outlines of the ancestral home are indistinct and the region has been overlaid with the modern administrative structure of modern Indonesia, the distinction between Ranah Minang and the rantau remains strong in societal perceptions and occurs repeatedly, not just in traditional folklore, but in modern expressions of traditional culture. This paper will describe the spatial division of territory in Minangkabau culture as it exists in the folklore of the group and will discuss the ways in which this traditional perception is manifested in modern society. Further, it will discuss the changing nature of the conception of Ranah Minang with respect to the physical landscape as well as to the institutions and structures of society.

Randomized controlled trial comparing traditional with two "mobile" epdural techniques

Background: The authors recently showed that “mobile” epidural analgesia, using low-dose local anesthetic–opioid mixtures, reduces the impact of epidural analgesia on instrumental vaginal delivery, relative to a traditional technique. The main prespecified assessment of pain relief efficacy, women’s postpartum estimates of labor pain after epidural insertion, did not differ. The detailed analgesic efficacy and the anesthetic characteristics of the techniques are reported here.
Methods: A total of 1,054 nulliparous women were randomized, in labor, to receive boluses of 10 ml 0.25% bupivacaine (traditional), combined spinal–epidural (CSE) analgesia, or lowdose infusion (LDI), the latter groups utilizing 0.1% bupivacaine with 2 g/ml fentanyl. Visual analog scale pain assessments were collected throughout labor and delivery and 24 h later. Details of the conduct of epidural analgesia, drug utilization, and requirement
for anesthesiologist reattendance were recorded.
Results: A total of 353 women were randomized to receive traditional epidural analgesia, 351 received CSE, and 350 received LDI. CSE was associated with a more rapid onset of analgesia, lower median visual analog scale pain scores than traditional in the first hour after epidural insertion, and a significant reduction in bupivacaine dose given during labor. Pain scores reported by women receiving LDI were similar to those in the traditional group throughout labor and delivery. Anesthesiologist reattendance was low but greater with each mobile technique.
Conclusions: Relative to traditional epidural analgesia, LDI is at least as effective and CSE provided better pain relief in the early stages after insertion. The proven efficacy of mobile epidurals and their beneficial impact on delivery mode make them the preferred techniques for epidural pain relief in labor.

Adoption of the world wide web by traditional Australian media organisations

The aim of this paper is it to identify whether Australian media companies moved online with a clear business model in mind or in an ad-hoc manner. In-depth interviews were conducted with four Internet media managers from two large Australian media organisations. All four had been involved in Web publishing from its early stages and had extensive knowledge of the development of Web publishing in the industry. The interviews focused on the period around the mid 1990’s when the early development of the organisations’ websites took place. We also review an analytical approach of examining narratives from research interviews developed by Davidson (Davidson 1997) and Mishler (Mishler1986a, 1986b).

Eccentric decline squat protocol offers superior results at 12 months compared with traditional eccentric protocol for patellar tendinopathy in volleyball players

Background: Conservative treatment of patellar tendinopathy has been minimally investigated. Effective validated treatment protocols are required.

Objectives: To investigate the immediate (12 weeks) and long term (12 months) efficacy of two eccentric exercise programmes for the treatment of patellar tendinopathy.

Methods: This was a prospective randomised controlled trial of 17 elite volleyball players with clinically diagnosed and imaging confirmed patellar tendinopathy. Participants were randomly assigned to one of two treatment groups: a decline group and a step group. The decline group were required to perform single leg squats on a 25° decline board, exercising into tendon pain and progressing their exercises with load. The step group performed single leg squats on a 10 cm step, exercising without tendon pain and progressing their exercises with speed then load. All participants completed a 12 week intervention programme during their preseason. Outcome measures used were the Victorian Institute of Sport Assessment (VISA) score for knee function and 100 mm visual analogue scale (VAS) for tendon pain with activity. Measures were taken throughout the intervention period and at 12 months.

Results: Both groups had improved significantly from baseline at 12 weeks and 12 months. Analysis of the likelihood of a 20 point improvement in VISA score at 12 months revealed a greater likelihood of clinical improvements in the decline group than the step group. VAS scores at 12 months did not differ between the groups.

Conclusions: Both exercise protocols improved pain and sporting function in volleyball players over 12 months. This study indicates that the decline squat protocol offers greater clinical gains during a rehabilitation programme for patellar tendinopathy in athletes who continue to train and play with pain.

Effect of low-dose mobile versus traditional epidural techniques on mode of delivery: a randomised controlled trial

Background

Epidural analgesia is the most effective labour pain relief but is associated with increased rates of instrumental vaginal delivery and other effects, which might be related to the poor motor function associated with traditional epidural. New techniques that preserve motor function could reduce obstetric intervention. We did a randomised controlled trial to compare low-dose combined spinal epidural and low-dose infusion (mobile) techniques with traditional epidural technique.
Methods

Between Feb 1, 1999, and April 30, 2000, we randomly assigned 1054 nulliparous women requesting epidural pain relief to traditional (n=353), low-dose combined spinal epidural (n=351), or low-dose infusion epidural (n=350). Primary outcome was mode of delivery, and secondary outcomes were progress of labour, efficacy of procedure, and effect on neonates. We obtained data during labour and interviewed women postnatally.
Findings

The normal vaginal delivery rate was 35·1% in the traditional epidural group, 42·7% in the low-dose combined spinal group (odds ratio 1·38 [95% CI 1·01–1·89]; p=0·04); and 42·9% in the low-dose infusion group (1·39 [1·01–1·90]; p=0·04). These differences were accounted for by a reduction in instrumental vaginal delivery. Overall, 5 min APGAR scores of 7 or less were more frequent with low-dose technique. High-level resuscitation was more frequent in the low-dose infusion group.
