Prevalence of pressure injury on the medical wards of public general hospitals in Kuwait: a national cross-sectional study.

BACKGROUND: Pressure injury is a severe problem that can significantly impact a patient's health, quality of life, and healthcare expenses. The prevalence of pressure injuries is a widely used clinical indicator of patient safety and quality of care. This study aims to address the research gap that exists on this topic in Kuwait by investigating the prevalence of pressure injuries and preventive measures on the medical wards of the country's public general hospitals. METHODS: A cross-sectional research design was adopted to measure the point prevalence of pressure injuries on 54 medical wards in the public general hospitals. Data, including variables pertaining to hospitals, patients, pressure injuries and preventive practices, were collected using an online form. The data were processed and analysed using Microsoft Excel and SPSS 23 (α level = 0.05). Analysis provided an overview of patient, pressure injury characteristics and preventive measures, and the relationships between the patient and pressure injury characteristics and the prevalence of pressure injuries. A model for predicting the determinants of pressure injury prevalence was constructed from a linear regression analysis. RESULTS: The mean national prevalence of pressure injury was 17.6% (95% CI: 11.3-23.8). Purely community-acquired pressure injuries represent the majority of pressure injuries nationally (58.1%). Regarding preventive measures, "pressure injury assessment on admission" has been provided to 65.5% of patients. Correlation analysis revealed that the only statistically significant correlation with the prevalence of hospital-acquired pressure injury was "pressure injury assessment on admission", which was strongly negative (ρ = -0.857). Therefore, this was the only variable included in the regression analysis as a predictor of pressure injury prevalence (Beta = 0.839). The results showed many statistically significant differences between hospitals with respect to the variables studied. CONCLUSIONS: The national pressure injury prevalence is high compared to the global rate. The higher percentage of purely community-acquired pressure injuries requires particular attention. Many risk factors for the development of pressure injuries are public health concerns, and effective mitigating strategies are needed. Further research is required to assess the knowledge, attitude, and behaviour of nurses with respect to pressure injuries, and to evaluate preventive and management practices.

[Experience in the use of plasma exposure with the use of NO-therapy in the treatment of chronic wounds of various etiologies]. / Opyt primeneniya plazmennogo vozdeistviya v sochetanii s NO-terapiei pri lechenii khronicheskikh ran raznoi etiologii.

Modern treatment of wounds of various etiologies is presented as a comprehensive approach, including correction of the general somatic condition and adequate local treatment in strict accordance with the stages of the wound process. In relation to the outpatient link, it is a local gentle management of wound defects with proper treatment of the wound surface and wound management under an adequate wound coating that meets various tasks at various stages of the inflammatory process. The inclusion in the therapy of chronic wounds of electro- and radio-frequency equipment with mandatory treatment with NO-streams has a positive effect on the regeneration processes. The inclusion in the therapy of chronic wounds of plasma torch treatment generated by electrosurgical high-frequency MEDSI devices followed by mandatory treatment with NO- flows by ALFANO device has a positive effect on the regeneration processes.

Pressure eye: In-bed contact pressure estimation via contact-less imaging.

Computer vision has achieved great success in interpreting semantic meanings from images, yet estimating underlying (non-visual) physical properties of an object is often limited to their bulk values rather than reconstructing a dense map. In this work, we present our pressure eye (PEye) approach to estimate contact pressure between a human body and the surface she is lying on with high resolution from vision signals directly. PEye approach could ultimately enable the prediction and early detection of pressure ulcers in bed-bound patients, that currently depends on the use of expensive pressure mats. Our PEye network is configured in a dual encoding shared decoding form to fuse visual cues and some relevant physical parameters in order to reconstruct high resolution pressure maps (PMs). We also present a pixel-wise resampling approach based on Naive Bayes assumption to further enhance the PM regression performance. A percentage of correct sensing (PCS) tailored for sensing estimation accuracy evaluation is also proposed which provides another perspective for performance evaluation under varying error tolerances. We tested our approach via a series of extensive experiments using multimodal sensing technologies to collect data from 102 subjects while lying on a bed. The individual's high resolution contact pressure data could be estimated from their RGB or long wavelength infrared (LWIR) images with 91.8% and 91.2% estimation accuracies in PCSefs0.1 criteria, superior to state-of-the-art methods in the related image regression/translation tasks.

An Integrated System of Braden Scale and Random Forest Using Real-Time Diagnoses to Predict When Hospital-Acquired Pressure Injuries (Bedsores) Occur.

BACKGROUND AND OBJECTIVES: Bedsores/Pressure Injuries (PIs) are the second most common diagnosis in healthcare system billing records in the United States and account for 60,000 deaths annually. Hospital-Acquired Pressure Injuries (HAPIs) are one classification of PIs and indicate injuries that occurred while the patient was cared for within the hospital. Until now, all studies have predicted who will develop HAPI using classic machine algorithms, which provides incomplete information for the clinical team. Knowing who will develop HAPI does not help differentiate at which point those predicted patients will develop HAPIs; no studies have investigated when HAPI develops for predicted at-risk patients. This research aims to develop a hybrid system of Random Forest (RF) and Braden Scale to predict HAPI time by considering the changes in patients' diagnoses from admission until HAPI occurrence. METHODS: Real-time diagnoses and risk factors were collected daily for 485 patients from admission until HAPI occurrence, which resulted in 4619 records. Then for each record, HAPI time was calculated from the day of diagnosis until HAPI occurrence. Recursive Feature Elimination (RFE) selected the best factors among the 60 factors. The dataset was separated into 80% training (10-fold cross-validation) and 20% testing. Grid Search (GS) with RF (GS-RF) was adopted to predict HAPI time using collected risk factors, including Braden Scale. Then, the proposed model was compared with the seven most common algorithms used to predict HAPI; each was replicated for 50 different experiments. RESULTS: GS-RF achieved the best Area Under the Curve (AUC) (91.20 ± 0.26) and Geometric Mean (G-mean) (91.17 ± 0.26) compared to the seven algorithms. RFE selected 43 factors. The most dominant interactable risk factors in predicting HAPI time were visiting ICU during hospitalization, Braden subscales, BMI, Stimuli Anesthesia, patient refusal to change position, and another lab diagnosis. CONCLUSION: Identifying when the patient is likely to develop HAPI can target early intervention when it is needed most and reduces unnecessary burden on patients and care teams when patients are at lower risk, which further individualizes the plan of care.

Machine Learning Techniques, Applications, and Potential Future Opportunities in Pressure Injuries (Bedsores) Management: A Systematic Review.

Pressure Injuries (PI) are one of the most common health conditions in the United States. Most acute or long-term care patients are at risk of developing PI. Machine Learning (ML) has been utilized to manage patients with PI, in which one systematic review describes how ML is used in PI management in 32 studies. This research, different from the previous systematic review, summarizes the previous contributions of ML in PI from January 2007 to July 2022, categorizes the studies according to medical specialties, analyzes gaps, and identifies opportunities for future research directions. PRISMA guidelines were adopted using the four most common databases (PubMed, Web of Science, Scopus, and Science Direct) and other resources, which result in 90 eligible studies. The reviewed articles are divided into three categories based on PI time of occurrence: before occurrence (48%); at time of occurrence (16%); and after occurrence (36%). Each category is further broken down into sub-fields based on medical specialties, which result in sixteen specialties. Each specialty is analyzed in terms of methods, inputs, and outputs. The most relevant and potentially useful applications and methods in PI management are outlined and discussed. This includes deep learning techniques and hybrid models, integration of existing risk assessment tools with ML that leads to a partnership between provider assessment and patients' Electronic Health Records (EHR).

An Integrated System of Multifaceted Machine Learning Models to Predict If and When Hospital-Acquired Pressure Injuries (Bedsores) Occur.

Hospital-Acquired Pressure Injury (HAPI), known as bedsore or decubitus ulcer, is one of the most common health conditions in the United States. Machine learning has been used to predict HAPI. This is insufficient information for the clinical team because knowing who would develop HAPI in the future does not help differentiate the severity of those predicted cases. This research develops an integrated system of multifaceted machine learning models to predict if and when HAPI occurs. Phase 1 integrates Genetic Algorithm with Cost-Sensitive Support Vector Machine (GA-CS-SVM) to handle the high imbalance HAPI dataset to predict if patients will develop HAPI. Phase 2 adopts Grid Search with SVM (GS-SVM) to predict when HAPI will occur for at-risk patients. This helps to prioritize who is at the highest risk and when that risk will be highest. The performance of the developed models is compared with state-of-the-art models in the literature. GA-CS-SVM achieved the best Area Under the Curve (AUC) (75.79 ± 0.58) and G-mean (75.73 ± 0.59), while GS-SVM achieved the best AUC (75.06) and G-mean (75.06). The research outcomes will help prioritize at-risk patients, allocate targeted resources and aid with better medical staff planning to provide intervention to those patients.

How effective is alternating pressure (active) air surfaces for preventing pressure ulcers? A Cochrane Review summary with commentary.

BACKGROUND: Pressure ulcers may develop in people with impaired mobility, sensation, or cognition. Alternating pressure (active) air beds, overlays and mattresses are commonly used to prevent pressure ulcers. OBJECTIVE: This Cochrane Review aimed to determine the effects of alternating pressure (active) air beds, overlays or mattresses compared with any support surface in preventing pressure ulcers. METHODS: The population addressed was people at risk of and with existing pressure ulcers. Studies comparing alternating pressure (active) air surfaces with any beds, overlays or mattresses were included. The outcomes studied were pressure ulcer incidence, patient support-surface-associated comfort, adverse events, health-related quality of life and cost-effectiveness. RESULTS: There were 32 studies with a total of 9058 participants. There is low certainty evidence that alternating pressure (active) air surfaces compared with foam surfaces may reduce the incidence of pressure ulcers. It is uncertain whether there is a difference in the proportion of people developing new pressure ulcers between alternating pressure (active) air surfaces and reactive water-filled, fibre, air, gel or standard hospital surfaces. CONCLUSION: The use of alternating pressure (active) air surfaces may reduce the incidence of pressure ulcers compared to foam surfaces. However, it is uncertain if it is superior to reactive air surfaces, water surfaces and fiber surfaces in preventing pressure ulcers.

Pressure Ulcers from the Medico-Legal Perspective: A Case Report and Literature Review.

INTRODUCTION: The identification of professional liability profiles related to the development of pressure injuries is a very thorny issue from a medico-legal perspective. This is because no matter how strict the applied prevention protocols applied may be, the development of such injuries is largely dependent on endogenous factors. This paper aims to investigate the medico-legal issues related to this topic through the exposition of one case of medico-legal litigation and a traditional review of the literature. METHODS: We performed a literature search using three databases (Pubmed, Scopus, and Web Of Science), restricting the search to the period between 2001 and 2021. We used "pressure ulcers" and "jurisprudence" as the main keywords. From an initial library of 236 articles, our selection resulted in 12 articles, which were included in the review. RESULTS: We identified the ever-increasing expectations of patients and the concept of automatic attribution of responsibility when a pressure ulcer develops as the primary reasons for the increase in litigation over the past 20 years. The related corrective measures are numerous: a strict adherence to guidelines, an adequate documentation of preventive measures, a risk assessment, family involvement, and a successful collaboration between physicians and government institutions. CONCLUSIONS: The biological complexity of the pathogenetic development of pressure ulcers makes the subject very delicate from the medico-legal point of view. In principle, it is possible to state that a very large proportion of such injuries are preventable, but that there remains a percentage of them that cannot be prevented. In such cases, only a proper documentary demonstration of the adequacy of preventive measures can exclude liability profiles.

A novel mathematical model including the wetness parameter as a variable for prevention of pressure ulcers.

Pressure ulcers are injuries caused by external conditions such as pressure, friction, shear, and humidity resulting from staying in the same position for a long time in bedridden patients. It is a serious problem worldwide when assessed in terms of hospital capacity, nursing staff employment and treatment costs. In this study, we developed a novel mathematical model based on one of our previous models to prevent pressure ulcers or delay injuries. The proposed model uses a human thermal model that includes skin temperature, hypothalamus temperature, regional perspiration coefficient, and unconsciously loss of water amount. Moreover, in our model, we defined a variable wetness parameter in addition to the parameters, pressure, temperature, and humidity. The proposed model is mathematically defined in detail and tested for a wide range of parameters to show the model's effectiveness in determining the pressure ulcer formation risk. The model is also compared with a model from the literature that based on only the general parameters, pressure, temperature, and humidity. The obtained results showed that the model determines the risk of the occurrence of the pressure ulcer more precisely than the compared one.

Bedsores Management: Efficiency Simulation of a New Mattress Design.

Bedsores, also known as pressure ulcers, are wounds caused by the applied external force (pressure) on body segments, thereby preventing blood supply from delivering the required elements to the skin tissue. Missing elements hinder the skin's ability to maintain its health. It poses a significant threat to patients that have limited mobility. A new patented mattress design and alternative suggested designs aimed to reduce pressure are investigated in this paper for their performance in decreasing pressure. A simulation using Ansys finite element analysis (FEA) is carried out for comparison. Three-dimensional models are designed and tested in the simulation for a mattress and human anthropometric segments (Torso and Hip). All designs are carried out in solidworks. Results show that the original design can redistribute the pressure and decrease it up to 17% less than the normal mattress. The original design shows better ability to decrease the absolute amount of pressure on the body. However, increasing the surface area of the movable parts results in less pressure applied to the body parts. Thus, this work suggests changing the surface area of the cubes from 25 to 100 cm2.

LimpiAD foam and the potential control of the pressure ulcers onset.

Pressure ulcers development is an undesirable event that often worsens the clinical condition of patients already affected by severe pathologies. Since the aetiology of this clinical complication is unclear yet, at current the primary approach to treat the problem is the adoption of suitable patients' assistance procedures. At the same time, the research focuses on finding medicaments or treatment strategies that could prevent the lesions and/or accelerate their healing. The international market's wide range of cosmetic/pharmaceuticals products is mainly topical preparations based on emollient agents to preserve or restore skin homeostasis. On the other hand, the skin microbiome's implication in the pressure ulcers occurrence is mainly unknown. Based on these assumptions, here we tested an innovative preparation, the LimpiAD foam, as a potential preventive strategy of pressure ulcers onset. The active component of this product is composed of hyaluronic acid conjugated with a bacterial cell wall fragment of C. acnes DSM 28251. For LimpiAD foam, we hypothesised a combined action of the two components on the skin tissue, an emollient effect due to the hyaluronic acid properties together with a modulatory effect on the skin microbiota carried out by the component of bacterial derivation. Our results supported the hypothesis and suggested a potential role of LimpiAD foam in pressure ulcers prevention.

Chitosan alginate nanoparticles as a platform for the treatment of diabetic and non-diabetic pressure ulcers: Formulation and in vitro/in vivo evaluation.

Chitosan and alginate are natural bioactive polymers with wound healing properties, in addition to chitosan's anti-bacterial properties. In this study, these two polymers were combined in a drug-free nanosystem with positive or negative surface charges, for the treatment of non-diabetic and diabetic pressure ulcers. Chitosan alginate nanoparticles (CA NPs) were prepared by a modified ionic gelation method. Interaction between the polymers and formation of the NPs were confirmed by Fourier-Transform infrared spectroscopy, differential scanning calorimetry and transmission electron microscopy. For in vivo study, selected CA NPs with optimum particle size, polydispersity index, positive and negative zeta potential, were evaluated for their pressure ulcers-healing effect using non-diabetic and diabetic rats. Rate of wound closure, histological examination and histomorphometric assessment were used to evaluate the CA NPs' wound healing potential. Positively and negatively charged CA NPs significantly enhanced wound closure rates, compared to control untreated group. Histological and histomorphometric analysis revealed higher quality and maturation of the formed granulation tissue, less inflammation and higher collagen content with positively charged CA NPs containing higher amount of chitosan. These results suggest that chitosan alginate nanoparticles offer a promising platform for diabetic and non-diabetic wound healing applications.

Frequency of repositioning for preventing pressure ulcers in patients hospitalized in ICU: protocol of a cluster randomized controlled trial.

BACKGROUND: Despite being considered preventable, ulcers due to pressure affect between 30 and 50% of patients at high and very high risk and susceptibility, especially those hospitalized under critical care. Despite a lack of evidence over the efficacy in prevention against ulcers due to pressure, hourly repositioning in critical care as an intervention is used with more or less frequency to alleviate pressure on patients' tissues. This brings up the objective of our study, which is to evaluate the efficacy in prevention of ulcers due to pressure acquired during hospitalization, specifically regarding two frequency levels of repositioning or manual posture switching in adults hospitalized in different intensive care units in different Colombian hospitals. METHODS: A nurse-applied cluster randomized controlled trial of parallel groups (two branches), in which 22 eligible ICUs (each consisting of 150 patients), will be randomized to a high-frequency level repositioning intervention or to a conventional care (control group). Patients will be followed until their exit from each cluster. The primary result of this study is originated by regarding pressure ulcers using clusters (number of first ulcers per patient, at the early stage of progression, first one acquired after admission for 1000 days). The secondary results include evaluating the risk index on the patients' level (Hazard ratio, 95% IC) and a description of repositioning complications. Two interim analyses will be performed through the course of this study. A statistical difference between the groups < 0.05 in the main outcome, the progression of ulcers due to pressure (best or worst outcome in the experimental group), will determine whether the study should be put to a halt/determine the termination of the study. CONCLUSION: This study is innovative in its use of clusters to advance knowledge of the impact of repositioning as a prevention strategy against the appearance of ulcers caused by pressure in critical care patients. The resulting recommendations of this study can be used for future clinical practice guidelines in prevention and safety for patients at risk. TRIAL REGISTRATION: PENFUP phase-2 was Registered in Clinicaltrials.gov ( NCT04604665 ) in October 2020.

Prone position pressure sores in the COVID-19 pandemic: The Madrid experience.

BACKGROUND: In the context of the COVID-19 pandemic, prone position (PP) has been frequently used in the intensive care units to improve the prognosis in patients with respiratory distress. However, turning patients to prone imply important complications such as pressure ulcers. The aim of this paper is to describe the prevalence and characteristics of prone-positioning pressure sores (PPPS) and analyze the related risk factors. METHODS: A case-control study was performed in Gregorio Maranon hospital in Madrid during the COVID-19 pandemic between April and May 2020. We enrolled 74 confirmed COVID-19 patients in critical care units with invasive mechanical ventilation who were treated with pronation therapy. There were 57 cases and 17 controls. Demographic data, pronation maneuver characteristics and PPPS features were analyzed. RESULTS: In the case group, a total number of 136 PPPS were recorded. The face was the most affected region (69%). Regarding the severity, stage II was the most frequent. The main variables associated with an increased risk of PPPS were the total number of days under pronation cycles, and PP maintained for more than 24 h. The prealbumin level at admission was significantly lower in the case group. All of the ulcers were treated with dressings. The most frequent acute complication was bleeding (5%). CONCLUSIONS: According to our study, PPPS are related to the characteristics of the maneuver and the previous nutritional state. The implementation of improved positioning protocols may enhance results in critical patient caring, to avoid the scars and social stigma that these injuries entail.

Engaging in the prevention of pressure injuries in spinal cord injury: A qualitative study of community-dwelling individuals' different styles of prevention in Switzerland.

Context: Spinal cord injury (SCI) is a complex chronic condition with multiple self-management requirements and a high prevalence of complications. Pressure injuries (PIs) are among the most common ones and represent a frequent reason for re-hospitalization. This study aimed to identify styles of prevention that individuals with SCI adopt to deal with the risk of developing PIs.Design: Qualitative explorative interview study. Data was collected through semi-structured interviews, which were transcribed verbatim and analyzed following the principles of thematic analysis.Setting: Switzerland.Participants: The participants were a purposive sample of community-dwelling Swiss residents with SCI for at least five years.Interventions: Not applicable.Outcome measures: Not applicable.Results: Although all participants (N = 20) showed at least a basic knowledge of prevention of PIs by describing some preventive measures, they had different prevention styles characterized by different behavioral patterns (i.e. complying with all recommended measures, performing only a selection of them or delegating them to others) and different beliefs and attitudes towards prevention.Conclusion: By identifying the style of prevention of an individual, it is possible to develop tailored interventions that have an impact on the factors which seem to play a role in determining the adoption of preventive behaviors (i.e. perceived susceptibility to PIs, attitudes towards prevention, and self-efficacy). Such interventions would constitute a concrete effort to support individuals with SCI during their self-management. Besides alleviating a frequent and disabling medical complication and contributing to an enhanced quality of life, these interventions might also help decrease healthcare costs.

Effect of health literacy of caregivers on survival rates of patients under palliative care.

AIM: In this study, we aimed to investigate the effect of health literacy of the patient caregiver on the care results of palliative care patients. METHODS: Two hundred and forty-two patients who were hospitalised in palliative care units of seven hospitals in the city in January 2018 were involved in the study. Mortality of the patients was checked 3 months later. A survey interrogating the sociodemographic characteristics of the patients and Turkish translation of Health Literacy Survey - European Union to measure the health literacy level of the caregivers were used. RESULTS: About 19.50% of the patient caregivers are in adequate (sufficient/perfect) HL group in term of general HL. Caregivers had difficulty to access information/knowledge of what to do in case of emergency. Prevalence of bedsore occurrence in patients whose caregiver has 'inadequate' HL is higher than patients whose caregiver has 'adequate' HL. Rate of 'inadequate HL' of the caregiver is higher in dead group. As the length of hospitalisation variable value increases 1 unit, risk of mortality decreases 2%. CONCLUSIONS: Health literacy levels of the individuals dealing with the care of palliative unit patients hospitalised in our region are low. Amelioration of health literacy of the caregivers will have a direct effect on patient health and prevention of complications. Improving health literacy must be a priority target for a more quality patient care and less complication. The issues that caregivers felt themselves insufficient should be addressed and necessary actions should be taken in the identified issues.

Comparison of Two Intervention Strategies on Prevention of Bedsores among the Bedridden Patients: A Quasi Experimental Community-based Trial.

BACKGROUND: More than 80% of bedridden patients develop bedsores in home care settings. Training of informal caregivers can significantly affect the quality of care to these patients. OBJECTIVE: The objective of this study is to compare the effectiveness of two caregiver training strategies on prevention of bedsores among bedridden patients. METHODS: The study was carried out in Chandigarh. The study center was at PGIMER, Chandigarh. Seventy-eight bedridden patients being taken care in their homes were identified. These were randomly allocated into two groups. Group A received Prevention Package I, i.e., self-instruction Manual (SIM), training, and counseling. Group B received Prevention Package 2, i.e., only SIM. All these patients were followed up periodically for 1 year. During each follow-up, patients were observed for bedsore development. Braden scale was used to assess the risk factors of bedsores. Katz scale was used to evaluate the level of functional dependence of patients. Descriptive statistics was used to analyze the data. RESULTS: The percentage reduction of number of patients at risk of bedsore development as per various domains of Braden Scale was more in Group A as compared to Group B on each successive visit. There was 100% improvement in mobility level in the patients who were totally dependent in both the groups. However, in moderately dependant patients, the improvement in mobility level was more (87%) in Group A as compared to Group B (75%). All the caregivers complied fully with instructions postintervention. CONCLUSION: Training of caregivers for the prevention of bedsores among the bedridden patients was effective in improving the practices of the caregivers and also in reducing the risk factors of bedsores. One-to-one training with SIM distribution yielded better results than the use of only SIM.

Clinical Study on Heat-sensitive Moxibustion in Preventing Bedsores after Ischemic Stroke / 上海针灸杂志

Objective To observe the clinical efficacy of heat-sensitive moxibustion in preventing bedsores after ischemic stroke. Method A hundred ischemic stroke patients were randomized into a treatment group and a control group, 50 cases each. The control group was intervened by ordinary nursing care, while the treatment group additionally received heat-sensitive moxibustion. Norton scale and hemodynamics [whole blood viscosity (low-shear, mid-shear and high-shear), hematocrit and erythrocyte sedimentation rate (ESR)] of the two groups were observed before and after the treatment, and the occurrences of bedsores in the two groups were compared. Result After the intervention, Norton scale and hemodynamic indexes were significantly changed in both groups (P<0.05). Norton scale and hemodynamic indexes in the treatment group were significantly different from those in the control group after the intervention (P<0.05). The occurrence rate of bedsores was 8.0％ in the treatment group versus 24.0％ in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Heat-sensitive moxibustion can effectively reduce the risk and occurrence of bedsores in ischemic stroke patients, and its mechanism is possibly related to the improvement of hemodynamics.

Bedsores successfully treated with topical phenytoin.

Phenytoin is normally used in epilepsy treatment. One of the side effect affecting a significative part of the treated patients is the gingival overgrowth. It could surely be a correlation between this stimulatory effect and the assessment of phenytoin in wound healing. In fact, some studies of the literature have shown that topical phenytoin promotes healing of traumatic wounds, burns and ulcers by decubitus or stasis (diabetic or venous) and we emphasize, in vitiligo, a particular attention into repigmentation. The related mechanism of action seems to be multifactorial. In the present paper topical phenytoin has been used as wound-healing agent in 19 documented cases of bedsores, divided in treated and placebo group. The used concentration of phenytoin was 5 mg/L dissolved in a water solution of 9 g NaCl /L (0.9% P/V of NaCl). Patches soaked with phenytoin solution were applied over the bedsores along 3 hours every 12 hours. Results showed that phenytoin treated patients healed their wounds significantly before (p<0.001) with respect to controls.

The Predictive Risk Factors for Bedsores of Terminal Cancer Patients Receiving Home-based Care

<p>Aim: To clarify the predictive risk factors for bedsores of terminal cancer patients receiving home-based care. Methods: A retrospective study was conducted involving 95 terminal cancer patients receiving home-based care, including people using services provided by home-visit care providers until death. Results: The numbers of patients with and without bedsores were 31 and 64, respectively. Bivariate analyses revealed that significant variables were the Ohura-Hotta scale (P=0.02), hyperactive delirium (P=0.005), contracture (P=0.008), and anemia (P=0.02). According to multivariable logistic analysis, significant variables were contracture (OR=16.55, P=0.0002) and hyperactive delirium (OR=4.22, P=0.008) as independent risk factors for bedsores. Discussion: For terminal cancer patients receiving home-based care, hyperactive delirium should also be considered as a predictive risk factor for bedsores.</p>
