ABSTRACT

INTRODUCTION: The purpose of the article is to present the results of the research aimed at establishing the current situation in the health care system in Slovenia and verifying whether the possibility and support exist for the introduction of a freelance medical specialist. METHODS: We conducted a survey among physicians and health care managers. The sample framework covered the total population of physicians and health care managers in Slovenia; surveys were completed by 318 physicians and 52 health care managers. RESULTS: The results of the quantitative research analysis provided an essential basis for and feedback information about possible areas for improving the current state of the health care system. The conclusions of semistructured interviews also considerably contributed to the elaboration of the freelance medical specialist proposal. CONCLUSION: The findings of the research point out the need for changes in the Slovenian health care system and the support of the research participants in the implementation of the freelance medical specialist proposal. In the participants' opinions, the possibility of introducing freelance medical specialists would change the work organisation, particularly in terms of additional formalised possibilities for practising in the medical profession, which would further contribute to the overall improvement of the health care system.

ABSTRACT

Development of drug-loaded wound dressings is often performed without systematic consideration of the changing wound environment that can influence such materials' performance. Among the crucial changes are the wound pH and temperature, which have an immense effect on the drug release. Detailed release studies based on the consideration of these changing properties provide an important aspect of the in vitro performance testing of novel wound dressing materials. A sodium carboxymethyl cellulose-based wound dressing, with the incorporated non-steroidal anti-inflammatory drug diclofenac, was developed and characterised in regard to its physico-chemical, structural and morphological properties. Further, the influence of pH and temperature were studied on the drug release. Finally, the biocompatibility of the wound dressing towards human skin cells was tested. Incorporation of diclofenac did not alter important properties (water retention value, air permeability) of the host material. Changes in the pH and temperature were shown to influence the release performance and have to be accounted for in the evaluation of such dressings. Furthermore, the knowledge about the potential changes of these parameters in the wound bed could be used potentially to predict, and potentially even to control the drug release from the developed wound dressing. The prepared wound dressing was also proven biocompatible towards human skin cells, making it interesting for potential future use in the clinics.

ABSTRACT

- The aim of the study was to evaluate the efficacy and safety of the new method of platelet-rich plasma activation in the form of platelet gel, used in the treatment of non-healing chronic lower leg ulcers. The study was prospectively randomized, double blind and placebo controlled. We treated 60 patients (42 males and 18 females, mean age 69.43 years, SD 14.74) with chronic lower leg ulcers of different etiologies. Thirty patients were treated with allogeneic platelet gel and 30 with hydrogel. Both groups were comparable for duration of ulcer and its size. Treatment was repeated once a week for three consecutive weeks and then the last examination was scheduled at 6 months of the first platelet gel application. The t-test was used to analyze independent samples. Healing of chronic wounds with platelet gel was statistically significantly more effective compared to the treatment with hydrogel (p<0.05). At 6 months of platelet gel application, the mean wound area in the experimental group decreased to 35.01% (SD 53.69) of the initial wound size. In the control group, the wound area decreased to 89.95% (SD 71.82) of the initial wound size (p=0.001). The circumference of the wounds diminished to 54.62% (SD 39.85) of the initial value in the experimental group, compared to 91.28% (SD 29.32) in the control group (p<0.001). Allogeneic platelet gel prepared by the new method used in this study was found to be a good treatment option for non-healing chronic wounds when other methods are ineffective.

ABSTRACT

Chronic wounds, especially in diabetic patients, represent a challenging health issue. Since standard treatment protocols often do not provide satisfactory results, additional treatment methods-like phototherapy using low-level light therapy-are being investigated. The aim of our study was to evaluate the effect of phototherapy with light-emitting diodes on chronic wound treatment in diabetic and non-diabetic patients. Since a sufficient blood supply is mandatory for wound healing, the evaluation of microcirculation in the healthy skin at a wound's edge was the main outcome measure. Forty non-diabetic patients and 39 diabetics with lower limb chronic wounds who were referred to the University Medical Center Ljubljana between October 2012 and June 2014 were randomized to the treated and control groups. The treated group received phototherapy with LED 2.4 J/cm2 (wavelengths 625, 660, 850 nm) three times a week for 8 weeks, and the control group received phototherapy with broadband 580-900 nm and power density 0.72 J/cm2. Microcirculation was measured using laser Doppler. A significant increase in blood flow was noted in the treated group of diabetic and non-diabetic patients (p = 0.040 and p = 0.033), while there was no difference in the control groups. Additional Falanga wound bed score evaluation showed a significant improvement in both treated groups as compared to the control group. According to our results, phototherapy with LED was shown to be an effective additional treatment method for chronic wounds in diabetic and non-diabetic patients.

ABSTRACT

BACKGROUND: Calcaneal fractures are relatively rare and difficult to treat. Treatment options vary based on the type of fracture and the surgeon's experiences. In recent years, surgical procedures have increasingly been used due to the better long-term results. We present a case where guided tissue regeneration was performed in a calcaneal fracture that needed primary subtalar arthrodesis. We used the principles of guided tissue regeneration from oral surgery to perform primary subtalar arthrodesis and minimize the risk of non-union. We used a heterologous collagen membrane, which acts as a mechanical barrier and protects the bone graft from the invasion of unwanted cells that could lead to non-union. The collagenous membrane also has osteoconductive properties and is therefore able to increase the osteoblast proliferation rate. CASE PRESENTATION: A 62-year-old Caucasian woman sustained multiple fractures of her lower limbs and spine after a fall from a ladder. Her left calcaneus had a comminuted multifragmental fracture (Sanders type IV) with severe destruction of the cartilage of her subtalar joint and depression of the Böhler's angle. Therefore, we performed primary arthrodesis of her subtalar joint with elevation of the Böhler's angle using a 7.3 mm titanium screw, a heterologous cortico-cancellous collagenated pre-hydrated bone mix, a heterologous cancellous collagenated bone wedge, and a heterologous collagen membrane (Tecnoss®, Italy). The graft was fully incorporated 12 weeks after the procedure and a year and a half later our patient walks without limping. We present a new use of guided tissue regeneration with heterologous materials that can be used to treat extensive bone defects after bone injuries. CONCLUSIONS: We believe that guided tissue regeneration using heterologous materials, including a heterologous collagen membrane that presents a mechanical barrier between soft tissues and bone as well as a stimulative component that enhances bone formation, could be more often used in bone surgery.

ABSTRACT

Staphylococcus aureus is among the most important human pathogens. It is associated with different infections and is a major cause of skin and soft tissue infections (SSTIs). The aim of our study was to compare S. aureus isolates associated with SSTIs with isolates obtained from healthy carriers in the Central Slovenia region in terms of antimicrobial susceptibility, genetic diversity by clonal complex (CC)/sequence type, spa type, and by toxin gene profiling. In total, 274 S. aureus isolates were collected prospectively by culturing wound samples from 461 SSTI patients and nasal samples from 451 healthy carriers. We have demonstrated high heterogeneity in terms of CCs and spa type in both groups of isolates. The main clone among SSTI strains was Panton-Valentine leukocidin gene (pvl) positive CC121, whereas the main clone among carrier strains was CC45 carrying a large range of toxin genes. The main spa type in both groups was t091. Pvl was more frequently present in SSTI strains (31.2% SSTI vs 3.6% carrier strains) and staphylococcal enterotoxin C was more frequently present in carrier strains (1.6% SSTI vs 17.0% carrier strains). We have also demonstrated that methicillin-resistant S. aureus was a rare cause (2.8%) of SSTIs in our region.

ABSTRACT

The loss of tissue is still one of the most challenging problems in healthcare. Efficient laboratory expansion of skin tissue to reproduce the skins barrier function can make the difference between life and death for patients with extensive full-thickness burns, chronic wounds, or genetic disorders such as bullous conditions. This engineering has been initiated based on the acute need in the 1980s and today, tissue-engineered skin is the reality. The human skin equivalents are available not only as models for permeation and toxicity screening, but are frequently applied in vivo as clinical skin substitutes. This review aims to introduce the most important recent development in the extensive field of tissue engineering and to describe already approved, commercially available skin substitutes in clinical use.

ABSTRACT

INTRODUCTION: Total extrusion and loss of the talus is a rare injury with a wide choice of appropriate treatment, but rarely resulting in a fully functional recovery. We report on an uncommon case, both for the severity of the injury and for the uncommon treatment due to the patient's rejection of secondary surgery. CASE PRESENTATION: We treated a 16-year-old Caucasian man with the most extreme variant of a totally extruded and lost talus, accompanied with complex injury of the soft tissues of the ankle and foot. The treatment included urgent microvascular foot reimplantation, microvascular muscle free flap transfer, and temporary fixation. This kind of injury should typically be treated by tibiocalcaneal arthrodesis. However, this was not performed, as after the successful early stages of the treatment he strongly objected to another surgery due to his fully functional status and the successful therapeutic results of our early treatment. CONCLUSIONS: The injury described in this case study would ordinarily be treated by amputation, but due to the well-executed treatment in the early stages after the injury, the outcome was satisfying. Surprisingly and against our expectations, the late results of the treatment were successful even without arthrodesis. He is now 37 years old and has a functional foot 21 years after the injury.

ABSTRACT

Chronic and acute infected wounds can pose a major clinical problem because of associated complications and slow healing. In addition to classic preparations for wound treatment, an array of modern dressings for chronic wound care are currently available on the market. These dressings are intended for the wounds due to intralesional physiological, pathophysiological and pathological causes and which failed to heal as expected upon the use of standard procedures. Classic materials such as gauze and bandage are now considered obsolete and of just historical relevance because modern materials employed in wound treatment, such as moisture, warmth and appropriate pH are known to ensure optimal conditions for wound healing. Modern wound dressings absorb wound discharge, reduce bacterial contamination, while protecting wound surrounding from secondary infection and preventing transfer of infection from the surrounding area onto the wound surface. The use of modern wound dressings is only justified when the cause of wound development has been established or chronic wound due to the underlying disease has been diagnosed. Wound dressing is chosen according to wound characteristics and by experience. We believe that the main advantages of modern wound dressings versus classic materials include more efficient wound cleaning, simpler placement of the dressing, reduced pain to touch, decreased sticking to the wound surface, and increased capacity of absorbing wound exudate. Modern wound dressings accelerate the formation of granulation tissue, reduce the length of possible hospital stay and facilitate personnel work. Thus, the overall cost of treatment is reduced, although the price of modern wound dressings is higher than that of classic materials. All types of modern wound dressings, their characteristics and indications for use are described.
