Standardizing the classification of skin tears: validity and reliability testing of the International Skin Tear Advisory Panel Classification System in 44 countries.

BACKGROUND: Skin tears are acute wounds that are frequently misdiagnosed and under-reported. A standardized and globally adopted skin tear classification system with supporting evidence for diagnostic validity and reliability is required to allow assessment and reporting in a consistent way. OBJECTIVES: To measure the validity and reliability of the International Skin Tear Advisory Panel (ISTAP) Classification System internationally. METHODS: A multicountry study was set up to validate the content of the ISTAP Classification System through expert consultation in a two-round Delphi procedure involving 17 experts from 11 countries. An online survey including 24 skin tear photographs was conducted in a convenience sample of 1601 healthcare professionals from 44 countries to measure diagnostic accuracy, agreement, inter-rater reliability and intrarater reliability of the instrument. RESULTS: A definition for the concept of a 'skin flap' in the area of skin tears was developed and added to the initial ISTAP Classification System consisting of three skin tear types. The overall agreement with the reference standard was 0·79 [95% confidence interval (CI) 0·79-0·80] and sensitivity ranged from 0·74 (95% CI 0·73-0·75) to 0·88 (95% CI 0·87-0·88). The inter-rater reliability was 0·57 (95% CI 0·57-0·57). The Cohen's Kappa measuring intrarater reliability was 0·74 (95% CI 0·73-0·75). CONCLUSIONS: The ISTAP Classification System is supported by evidence for validity and reliability. The ISTAP Classification System should be used for systematic assessment and reporting of skin tears in clinical practice and research globally. What's already known about this topic? Skin tears are common acute wounds that are misdiagnosed and under-reported too often. A skin tear classification system is needed to standardize documentation and description for clinical practice, audit and research. What does this study add? The International Skin Tear Advisory Panel Classification System was psychometrically tested in 1601 healthcare professionals from 44 countries. Diagnostic accuracy was high when differentiating between type 1, 2 and 3 skin tears using a set of validated photographs.

[Pressures ulcers, basis of prevention and treatment in the elderly]. / Personne âgée et escarres: prévention et traitement.

Pressure sore is a frequent and painful pathology in the elderly. Upon hospitalization, risk assessment and prevention must be systematic. Pressure ulcer treatment will combine prevention principles, local debridement and moisture control. The interdisciplinary interventions of other health professionals (such as occupational therapist, physiotherapist, dieticians) can be crucial. Last but not least: for wound treatment to be a success, the patient must be considered in his globality.

Cutaneous lumbosacral Herpes simplex virus among patients hospitalized for an advanced disease.

BACKGROUND: Cutaneous Herpes simplex virus (HSV) infections are regularly observed in lumbosacral areas, and many are refractory to appropriate initial diagnosis and management. OBJECTIVE: We aimed to evaluate the incidence of lumbosacral HSV among advanced disease patients, to estimate their survival index from HSV onset, and to describe their clinical and virological characteristics. METHODS: A prospective, descriptive study was conducted in a palliative and continuous care centre, collecting patients with suspected cutaneous HSV lesions in the lumbosacral area. RESULTS: From 2008 to 2010, 24 patients were included: 19 had HSV-2 confirmed by at least one laboratory test. Incidence of HSV-2 was 2.67% (1.73-4.33%, 95% CI). No age, gender or survival differences were observed compared to the global population in the centre. Most lesions were detected early as vesicles (14/24) or small ulcers. Sensitivity was good for all diagnostic methods (62.5% for immunofluorescence and 79.2% for culture and/or PCR). Outcome was favourable under classical antiherpetic drugs and topical antiseptic dressing. CONCLUSIONS: Cutaneous lumbosacral HSV remains uncommon in patients hospitalized with advanced diseases. Most of these patients suffer from pressure ulcers or other dermatitis; we advocate increased attention of this diagnosis to avoid skin complications and added pain.

[Expansion of the sphere of crisis: the question of the intrusiveness of the disease]. / Extension du domaine de la crise: la question de l'intrusion de la maladie.

The passage to ambulatory care of a patient with a long hospital stay due to a wrenching disease is not something obvious. The doctor and the care staff will have to take up the challenge of dealing with an important amount of care. The quality of life of the patient and his caregivers is influenced by the neuropsychiatric disorders, the illness intrusiveness and the depression that come along with them. The chronic disease intruding causes a crisis in their lives. In order to better evaluate these factors we are using the Illness Intrusiveness Rating Scale developed by Devins. This article addresses the high complexity of clinical situations handled in an environment of rehabilitation care with the support of the consultants, nurses and doctors, of the liaison psychiatry.

Plantar pressure distribution in Type 2 diabetic patients without peripheral neuropathy and peripheral vascular disease.

AIMS: To evaluate the distribution of plantar pressure during walking on a level gradient in patients with Type 2 diabetes mellitus without any microvascular and macrovascular complications and to compare them with non-diabetic control subjects. METHODS: A group of 15 patients with Type 2 diabetes mellitus without either peripheral neuropathy or peripheral vascular disease (PVD), as well as without both diabetic retinopathy and nephropathy, was compared with a group of 15 non-diabetic subjects matched for age, sex, body weight and height. The plantar pressure and duration of plantar pressure were measured on big toe, 1st, 3rd and 5th metatarsal heads, and on the heel of both feet by Force Sensing Resistors sensors. The static contact plantar surface was measured by method of Harris footprints. RESULTS: The diabetic group showed a significant increase in peak plantar pressure at the level of the big toe [right foot 205 +/- 94 vs. 101 +/- 39 kPa (mean +/- SD), P = 0.01; left foot 165 +/- 61 vs. 104 +/- 43 kPa, P = 0.05] and 5th metatarsal head (right foot 160 +/- 68 vs. 97 +/- 32 kPa, P = 0.05; left foot 174 +/- 65 vs. 91 +/- 42 kPa, P = 0.02) with a significantly prolonged duration of plantar pressure at each step. Under the heel, the peak plantar pressure was significantly lower in the diabetic group (right foot 187 +/- 54 vs. 321 +/- 91 kPa, P = 0.05; left foot 184 +/- 63 vs. 298 +/- 110 kPa, P = 0.05). No significant differences were noted under 1st and 3rd metatarsal heads. The contact plantar surface was significantly reduced in the diabetic group compared with control subjects (right foot 118.2 +/- 10.8 vs. 141.5 +/- 12.7 cm2, P = 0.05; left foot 127.5 +/- 8.7 vs. 140.0 +/- 11.1 cm2, P = 0.05). CONCLUSIONS: We observed an anterior displacement of weight-bearing during walking on a level gradient as well as a reduced static contact plantar surface in diabetic patients without evidence of any complications compared with the non-diabetic control group. This could be a premature sign of peripheral neuropathy, which is not evaluated on clinical examination or quantitative sensory testing used in clinics.

Is time since hip fracture influencing the discrimination between fractured and nonfractured subjects as assessed at the calcaneum by three technologically different quantitative ultrasound devices?

Because quantitative ultrasound (QUS) instruments from different manufacturers have significant technical differences, it is difficult to assess whether all of them can discriminate similarly between osteoporotic fractures and age-matched controls. Thus, to avoid any bias, reliable comparative assessment of the QUS devices should be carried out on the same population. Few studies have fulfilled this condition. Another source of variability in cross-sectional studies in which fractured and nonfractured subjects are compared is the time since osteoporotic fracture. Our study evaluated the ability of three calcaneal QUS devices to discriminate patients with osteoporotic hip fracture from control subjects, using the same population. In addition, a subset of patients was re-measured about 9 months after the hip replacement surgery to check how the time since fracture affects the discriminatory ability of the different QUS devices. Fifty postmenopausal hip-fractured patients and 46 postmenopausal age-matched controls were included in this study and measured on three QUS devices, as well as 50 young healthy controls to calculate the T-score. Odds ratio results showed that a decrease in UBIS trade mark BUA of 1 SD was associated with a significant increase in fracture risk (odds ratio adjusted = 2.30) comparable with Sahara broadband ultrasound attenuation (BUA) (OR adj. = 2.30), and Achilles BUA (OR adj. = 3.5). However, given the large overlap between the 95% intervals of each OR and for the areas under ROC curves, no significant difference was found between them. In the subset of 15 hip-fractured subjects, no significant differences were found between ultrasound parameters of the first visit and 9 months after except for the heel width (soft tissue variation). Odds ratio and areas under the curve (AUC) tend to increase from visit 1 to 2 for the BUA and decrease substantially for the SOS for all but the Lunar Achilles+. Nonsignificant correlation was found between the absolute difference of the ultrasound parameters measured at the two visits and the time since fracture, except for the Sahara SOS (r = 0.45; P < 0.04). In conclusion, no significant differences between QUS technologies were observed in their positive and significant ability to discriminate hip-fractured patient from controls. However, this statement is shadowed when taking into account the time since fracture which seems to negatively influence results obtained on dry versus wet QUS systems. As a result, it is advisable that such parameters would be taken into account when designing a study aimed to demonstrate the discriminatory ability of heel ultrasound between normal and hip-fractured patients.

Symptoms of recurrent intrathecal baclofen withdrawal resulting from drug delivery failure: a case report.

A 24-yr-old, completely (T8) paraplegic male patient presenting with severe spasticity had a drug administration device implanted in April 1991 for continuous intrathecal administration of baclofen. After a period of remarkable improvement in both the spasticity level and his quality of life, the patient experienced several short-lasting episodes of increased spasticity, with severe spasms. Among the possible causes of these deleterious episodes were microcrystalluria, obstipation, a decubitus ulcer, a foreign body in the buttocks, drug tolerance to baclofen, electromagnetic interference, and erroneous filling and programing of the pump. The catheter was the most common source of intrathecal baclofen withdrawal symptoms and had to be changed four times in 5 yr. Intrathecal baclofen administered through an implantable drug administration device is a highly effective but complex and expensive procedure that requires careful patient selection and close monitoring by highly qualified and well-trained health professional. Withdrawal symptoms may be related to noncompliance on the part of the patient, erroneous filling or programing of the pump, depletion of the battery, random component failure, concomitant illness, drug tolerance, or advancement of the disease itself. When failure of the device is suspected, substitution with oral baclofen is recommended until a full work-up is performed to determine the defect.

Percutaneous endoscopic gastrostomy in neurological rehabilitation: a report of six cases.

PURPOSE: This study reports the cases of six patients with severe chronic neurological disability and swallowing difficulties due to traumatic brain injury (TBI), anoxia and multiple sclerosis (MS). METHOD: The patients required nutritional supplement through percutaneous endoscopic gastrostomy (PEG). RESULTS: Their clinical follow-up showed a decrease of intercurrent medical complications, especially pressure sores. In addition, an improvement of oropharyngeal function was observed in some patients, also accompanied by slightly better basic psychomotor functions such as vigilance, sustained attention and tone or motor control. However, not every patient did improve with this procedure. The two MS patients benefited most, while the improvement was less homogenous in the three TBI patients. CONCLUSIONS: The advantages of PEG over nasogastric tube on oropharyngeal function can be related to the absence of pharyngeal irritation and its role in overall recovery could be due to an increase in social activities, a control of infections, a better rehabilitation schedule and a long-term effect on brain function due to better nutritional support.

Early modifications of biochemical markers of bone metabolism in spinal cord injury patients. A preliminary study.

Spinal cord injury is associated with the development of a rapid and severe osteoporosis which might reflect uncoupling between bone formation and resorption. A prospective study was made in 6 spinal cord injury patients followed up to 2-3 months after onset with various markers of a) bone formation: osteocalcin and C-terminal peptide of type I procollagen, b) bone resorption: pyridinolines and C-terminal telopeptide of type I collagen, c) connective tissue metabolism: amino-terminal propeptide of type III collagen (PIIINP). Preliminary results show that early after onset, bone formation was depressed as compared to dramatically increased bone resorption. Low bone formation rate lasted two weeks before it began to raise, while bone resorption showed a continuous tendency to increase. The dramatic increase in PIIINP levels might represent some attempt of bone to repair. This paper describes the evolution of various biochemical markers of bone and connective tissue metabolism after onset of paralysis and critically reviews the use of those markers in patients with spinal cord injury.
