Topical anaesthetic effects on skin vasculature with potential implications for laser treatment.

Laser treatment of vascular lesions is affected by parameters including the diameter and depth of the vessels and flow within the vessels. Topical anaesthetics are in common use prior to laser treatment but may have effects on vessel parameters and, subsequently, the efficacy of laser treatment. Eleven patients with capillary vascular malformations were investigated for vessel diameter before and after elective application of a topical anaesthetic, Eutectic Mixture of Local Anaesthetics (EMLA) (AstraZeneca) or Ametop (S&N Health), prior to pulsed dye laser treatment.

Evidence of purinergic neurotransmission in isolated, intact horse sweat glands.

Background: Fluid secretion by sweat glands in response to heat and exercise is underpinned by increases in intracellular calcium. In horses, this is primarily via β2-adrenoceptors, but studies in equine sweat gland cell lines have indicated a possible role for purinergic agonists. Knowledge of equine sweating stimulus-secretion mechanisms in intact glands from healthy animals would allow future comparison to determine whether these mechanisms are affected in equine anhidrosis.

Older people's views on what they need to successfully adjust to life with a hearing aid.

This article reports a study exploring what older people believe would enable them to adjust to and gain maximum benefit from wearing a hearing aid. A mixed methods approach was employed during 2006 involving interviews with key stakeholders, a survey across three Scottish health board areas and focus groups. Nine key stakeholders from six national and local organisations were interviewed about the needs of older people being fitted with hearing aids.

The secretory clear cell of the eccrine sweat gland as the probable source of excess sweat production in hyperhidrosis.

Primary hyperhidrosis is characterized by excessive sweating in palmar, plantar and axillary body regions. Gland hypertrophy and the existence of a third type of sweat gland, the apoeccrine gland, with high fluid transporting capabilities have been suggested as possible causes. This study investigated whether sweat glands were hypertrophied in axillary hyperhidrotic patients and if mechanisms associated with fluid transport were found in all types of axillary sweat glands.

Physiological and immunocytochemical evidence that glutamatergic neurotransmission is involved in the activation of arm autotomy in the featherstar Antedon mediterranea (Echinodermata: Crinoidea).

The crinoid echinoderm Antedon mediterranea autotomises its arms at specialised skeletal joints known as syzygies that occur at regular intervals along the length of each arm. Detachment is achieved through the nervously mediated destabilisation of ligament fibres at a particular syzygy. The aim of this investigation was to identify neurotransmitters that are involved in the autotomy response.

Analyzing free-living physical activity of older adults in different environments using body-worn activity monitors.

This study measured objectively the postural physical activity of 4 groups of older adults (> or =65 yr). The participants (N = 70) comprised 3 patient groups--2 from rehabilitation wards (city n = 20, 81.8 +/- 6.

Interprofessional attitudes and perceptions: Results from a longitudinal controlled trial of pre-registration health and social care students in Scotland.

This study made use of a controlled longitudinal design to assess the impact on pre-registration health and social care students of an interprofessional intervention on the attitudes to and perceptions of interprofessional ideals. Evaluation, over four years, of Nursing, Occupational Therapy, Podiatry, Prosthetics and Orthotics, Physiotherapy and Radiography students was performed using the adapted versions of the Readiness for Interprofessional Learning Scale (RIPLS) and the Interdisciplinary Education Perception Scale (IEPS). Baseline samples of the control and experimental groups were 260 and 313 respectively.

A direct comparison of pulsed dye, alexandrite, KTP and Nd:YAG lasers and IPL in patients with previously treated capillary malformations.

Introduction: Several studies have reported laser treatment of Capillary Malformations (CMs) using systems other than pulsed dye lasers (PDL). Few, however, have compared different systems in the same patients. This study aimed to directly compare CM fading using five different systems.

Gait characteristics of subjects with chronic fatigue syndrome and controls at self-selected and matched velocities.

Background: Gait abnormalities have been reported in individuals with Chronic Fatigue Syndrome (CFS) however no studies exist to date investigating the kinematics of individuals with CFS in over-ground gait. The aim of this study was to compare the over-ground gait pattern (sagittal kinematics and temporal and spatial) of individuals with CFS and control subjects at their self-selected and at matched velocities.

Methods: Twelve individuals with CFS and 12 matched controls participated in the study.

The Interdisciplinary Education Perception Scale (IEPS): an alternative remodelled sub-scale structure and its reliability.

The original 4 sub-scale version of the Interdisciplinary Education Perception Scale (IEPS) was published by Luecht et al. (1990, Journal of Allied Health, 181 - 191). There appears however to be a lack of evidence of the stability of the original instrument and of the test-retest reliability of the items and sub-scales when used with undergraduates.

Recurrence of spider naevi following treatment with 585 nm pulsed dye laser.

During a 2-year period 201 patients underwent treatment for spider naevi with a 585nm pulsed dye laser at Canniesburn Hospital Laser Suite. Patients were treated with a either single or double pulse technique. Of these patients 191 (95%) had a successful result, with clearance in a mean of 1.

Staff attitudes towards working with drug users: development of the Drug Problems Perceptions Questionnaire.

Aim: To evaluate the psychometric properties of an adaptation of the Alcohol and Alcohol Problems Perceptions Questionnaire to measure the attitudes of staff to working with drug users (the DDPPQ).

Design: Postal survey: a questionnaire was mailed to participants on two occasions.

Setting: A large urban National Health Service (NHS) mental health service.

The test-retest reliability of a revised version of the Readiness for Interprofessional Learning Scale (RIPLS).

The original version of the Readiness for Interprofessional Learning Scale (RIPLS) was published by Parsell and Bligh in 1999. The only aspect of reliability considered by the authors was the internal consistency. A revised version for use with undergraduate students was published in 2005 (McFadyen et al.

The efficiency of an air filtration system in the hospital ward.

A study was conducted to ascertain the efficiency and effectiveness of an air filtration system (Electromedia Model 100C, Clean Air UK, UK) in the hospital ward. The sampling was conducted using a portable Surface Air Sampler (Cherwell Laboratories, Bicester, UK) in conjunction with settle plates. Samples were taken two days before and two days following activation of the filtration system and results compared.

The effect of varying pulse duration, wavelength, spot size, and fluence on the response of previously treated capillary vascular malformations to pulsed-dye laser treatment.

Modern lasers allow different parameters to be altered in an effort to gain further improvement in otherwise resistant capillary vascular malformations (CMs). The aim of this study was to examine the effect of changing the pulse duration, wavelength, spot size, and fluence on the color and capillary architecture of 585-nm pulsed-dye, laser-resistant CMs. Eighteen patients were assessed with a depth measurement videomicroscope (DMV) before and after 12 test patches with ScleroPlus and V-Beam lasers at specified parameters.

Influence of policies on nursing practice in long-term care environments for older people.

Aim: This paper reports a study exploring nurses' awareness of, access to and use of policies within long-term care environments for older people in Scotland.

Background: The provision of the highest quality of nursing care for older people with continuing care needs is facilitated through a number of strategic mechanisms. These encompass regulatory systems, national and local policies and care guidance.

Perception of risk: a study of A&E nurses and NHS managers.

This exploratory study investigates perceptions of two groups of NHS staff, of a range of risks, topical and relevant to accident and emergency (A&E). Literature suggests that the effectiveness of a risk management strategy is lessened if staff exposed to risk, and managers, have different perceptions of the nature and severity of the risk. A self-administered questionnaire was distributed to registered A&E nurses and to Trust managers at directorate level and above, working in five large inner-city NHS Trusts.

The use of an air filtration system in podiatry clinics.

A small-scale study was conducted to ascertain the efficiency and effectiveness of an air filtration system for use in podiatry/chiropody clinics (Electromedia Model 35F (A), Clean Air Ltd, Scotland, UK). Three clinics were identified, enabling comparison of data between podiatry clinics in the West of Scotland. The sampling was conducted using a portable Surface Air Sampler (Cherwell Laboratories, Bicester, UK).

The effect of exercise on gait and balance in patients with chronic fatigue syndrome.

This study investigated anecdotal reports of gait and balance abnormalities in subjects with Chronic Fatigue Syndrome (CFS) by examining the effects of a light exercise test on postural sway and various gait parameters. Tests were performed on 11 CFS patients and 11 age- and sex-matched sedentary controls. Results demonstrated that postural sway was not significantly different in both groups before or after the exercise test.

Risks of respiratory disease in the heavy clay industry.

Objectives: Little information is available on the quantitative risks of respiratory disease from quartz in airborne dust in the heavy clay industry. Available evidence suggested that these risks might be low, possibly because of the presence in the dust of other minerals, such as illite and kaolinite, which may reduce the harmful effects of quartz. The aims of the present cross sectional study were to determine among workers in the industry (a) their current and cumulative exposures to respirable mixed dust and quartz; (b) the frequencies of chest radiographic abnormalities and respiratory symptoms; (c) the relations between cumulative exposure to respirable dust and quartz, and risks of radiographic abnormality and respiratory symptoms.

Demonstration of delayed recovery from fatiguing exercise in chronic fatigue syndrome.

Patients with the chronic fatigue syndrome (CFS) complain consistently of delay in recovery of peripheral muscle function after exercise. The purpose of this study was to try to confirm this observation. A fatiguing exercise test was carried out on the quadriceps muscle group of ten patients and ten control subjects.

Relations between upper limb soft tissue disorders and repetitive movements at work.

To make a preliminary assessment of whether upper limb soft tissue disorders might be associated with activities at work, we have conducted a case-control study of subjects attending orthopedic clinics in three cities. All subjects between the ages of 16 and 65 years, in whom defined soft tissue conditions of the upper limb were diagnosed by the participating orthopedic surgeons, were invited to take part. Controls were subjects attending the same clinics within the same age range whose clinical diagnosis did not include disease of the upper limb, cervical or thoracic spine.

Development of the Regular Interlaboratory Counting Exchanges (RICE) scheme to include visual reference counts and samples from asbestos clearance operations.

The RICE proficiency testing scheme for asbestos fibre counting operated until 1992 with industrial samples and with reference counts produced by an image analyser (Magiscan). The visual counts produced in RICE by the participating laboratories have now been used to develop a reliable reference count for these industrial samples. Concurrently with the routine participation in RICE, laboratories also counted samples from asbestos clearance operations; these counts were used to develop suitable reference counts and performance limits for this type of sample.
