Small steps: physical health promotion for people living with mental illness

Physical health promotion for people with mental illness is vital if the life expectancy of this population group is to be improved. While there is promising evidence of physical health promotion initiatives in the literature in this population group, it is unclear whether these have resulted in long-term gains and actually reduced morbidity and mortality. We aimed to identify which physical health promotion strategies and resources were most likely to resonate with people who have long-term mental health problems and live in the community. We facilitated three focus groups in metropolitan Perth with 27 participants who experienced long-term serious mental health problems for this qualitative study. Participants were clear about which health promotion resources and approaches they did or did not consider would engage them. Participants wanted health messages that were positive, clear and not too wordy. They tended to dislike pamphlets and preferred DVDs. They also preferred to participate in health promotion activities in groups. Participants were aware of the need to engage in health protective behaviours but were often overwhelmed by their mental health problems. Health promotion for this population group ought to capitalise on therapeutic alliances with staff and informal peer networks already established in drop-in centres and clubhouses.     

Lumbosacral plexopathy in gunshot wounds and motor vehicle accidents: comparison of electrophysiologic findings

OBJECTIVE: To characterize the differences between injuries to the lumbosacral (LS) plexus caused by gunshot wounds (GSW) and motor vehicle crashes (MVC) with regard to the location and extent of involvement. DESIGN: A retrospective review of electrophysiologic data from an electromyography laboratory of a county hospital. Nineteen patients with GSW and ten patients with MVC diagnosed by electromyography with an LS plexopathy were included in the study. Injuries were categorized by the number of anatomic quadrants of the LS plexus: upper anterior, upper posterior, lower anterior, and lower posterior. Comparison of upper vs. lower portions and bilaterality of LS plexus involvement was also made. Statistical analyses were performed with two-tailed Fisher's exact and general association tests. RESULTS: Lower portions of the plexus were involved more frequently in patients with MVC compared those observed in patients with GSW. Upper portions of the LS plexus were more involved compared with the lower portions in patients with GSW injuries. More sections of the plexus were involved in patients with MVC compared with those in patients with GSW. CONCLUSIONS: Compared with patients with MVC, patients with GSW had a greater chance of involvement of the upper portion of the plexus. The reverse was true for the lower portion. Hopefully this information will aid the electromyographer and rehabilitation team in the diagnosis and treatment of traumatic plexopathies caused by different etiologies.     

Heart disease and depression: don't ignore the relationship

Evidence is mounting that depression is a risk factor for the development of cardiovascular disease and portends a worse outcome in cardiac patients. Depression can be easily diagnosed and safely treated in cardiac patients, but it is undertreated.     

What is a safe waiting time for coronary artery bypass surgery?

To determine the factors that influenced doctors' prioritization and decisions on safe waiting time for coronary artery bypass surgery, 50 'paper patients', based on a random sample of cases who actually had surgery, were assessed by 33 clinicians. We used linear regression models to reflect the impact of clinical and non-clinical 'cues' on safe waiting time and priority decisions. The benefits of surgery tended to be over-estimated. For example, the average perceived gain in life expectancy for patients with left main-stem disease was 6.74 years. However, models incorporating only the perceptions of benefit as independent variables (i.e. the anticipated symptom reduction, MI risk reduction and life expectancy extension), had only modest explanatory power (mean R2 was 0.55 for safe waiting time, and 0.56 for priority decisions). Models which incorporated perceptions of benefit and the cases' clinical and non-clinical characteristics had generally much higher explanatory power (mean R2, 0.83 and 0.86, respectively). Lifestyle and demographic variables had much less impact on the doctors' judgements than the major clinical cues of angina severity and left main-stem stenosis. Demographic and lifestyle cues had different impacts on safe waiting time and priority for about 25% of doctors.      

Chagas' disease (American trypanosomiasis)

This series is based on the Infectious Diseases section of the web site Refugee Health ∼ Immigrant Health, available on the World Wide Web at http://www.baylor.edu/~Charles_Kemp/refugee_health.htm . The site was developed through a contract with the Texas Department of Health as part of an ongoing effort to improve the health of refugees and immigrants.     

Bearing exchange in the management of pseudotumours

Introduction

Soft tissue reactions following metal-on-metal (MoM) arthroplasty of the hip have been under considerable discussion. These reactions are seen following both hip resurfacing and MoM total hip arthroplasty (THA). The phenomenon may arise owing to shedding of metal particles in high wear states, hypersensitivity with normal metal wear rates or a combination of the two.

Methods

Three patients were identified who had developed a soft tissue reaction (pseudotumour) following MoM hip resurfacing procedures. The prostheses were revised to ceramic-on-ceramic (CoC) THA with only minimal debridement of the pseudotumour. Pre and postoperative magnetic resonance imaging was performed to assess the size of the lesions.

Results

Progressive and satisfactory resolution of the associated pseudotumours was identified following revision of the prostheses to CoC THA.

Conclusions

In the early stages of pseudotumour formation following MoM hip resurfacing, this potentially devastating condition can be managed adequately with revision to a CoC bearing THA with minimal soft tissue excision.     

Preliminary report: skeletal muscle cell lipid and oxygen supply

In a group of 12 normal-weight, normotensive, nondiabetic adult females, the intramyocellular lipid (IMCL) to creatine ratio of the soleus muscle was determined using localized (1)H-magnetic resonance spectroscopy ((1)H-MRS) and related to skeletal muscle blood (and oxygen) supply (as assessed by near infrared spectroscopy [NIRS] of the forearm). A significant positive association was found between IMCL content and reoxygenation rate of forearm muscle hemoglobin (Hb) after 1 minute of ischemic exercise (r = .70, P = .01). The relative efficiency of skeletal muscle oxygen supply may be a determining factor of IMCL content in skeletal muscle.

Combined robotic lobectomy and adrenalectomy for lung cancer and solitary adrenal metastasis

Background and Objectives:

Surgical resection of isolated adrenal metastasis in primary lung cancer is associated with improved survival. We report a combined robotic lobectomy and adrenalectomy for resection of a primary lung cancer and metastasis to the adrenal gland.

Methods:

A 69-year-old male with a significant smoking history and shortness of breath was found to have a 3-cm left upper lobe mass with an enlarged left adrenal gland measuring 1.5cm. The adrenal gland was biopsied confirming metastatic poorly differentiated carcinoma, likely lung cancer. Computed tomography, positron emission tomography, and mediastinoscopy revealed no evidence of disease outside the adrenal gland.

Results:

Following induction chemotherapy, the patient underwent combination robotic lobectomy, lymphadenectomy, and adrenalectomy while in the same lateral decubitus position. Thoracic and urologic oncology teams performed their respective portions of the operation. Overall operative time was 4 hours, and length of hospital stay was 3 days. Estimated blood loss was 150mL with no narcotic requirements beyond the first postoperative day. Final pathology revealed large cell carcinoma of the lung with metastasis to the adrenal. All surgical margins were negative.

Conclusions:

Combination robotic lobectomy and adrenalectomy is feasible and can be associated with a short convalescence, minimal pain, and an oncologically sound approach.
