Vacuum – assisted closure in neurosurgery as treatment option for purulent wounds after spinal implants procedures – short preliminary report

We present a short preliminary report about the use of vacuum - assisted closure in infected and purulent wounds treatment after neurosurgical spinal procedures. Our report is based on the currently treated patients and points out to other neurosurgeons this therapeutic possibility. We are currently treating two severely injured patients in bad functional state. These patients had severe spine injuries and were therefore treated surgically by decompression and fusion. Patient No. 1 had C5 burst fracture treated by anterior and posterior stabilization, while patient No. 2 had Th4 burst fracture treated with posterior transpedicular stabilization. The patients developed purulent surgical site infection. Revision and wounds irrigation were ineffective. Desire to leave titanium implants in patient’s spines (which is important for future rehabilitation), it was decided to use V.A.C® in wounds healing. We find that vacuum - assisted closure appears to be of significant benefit in such treatment. It is a good therapeutic option in the management of such patients; however, this issue requires more extensive research in the future

Extensive ossifications of falx cerebri – literature review based on own experience and case report

Extensive ossification of the falx cerebri occur rarely however are described in the world literature references. Ossifications may concern both cerebral falx and other dural structures: tentorium. They are most often incidental findings and occurrence frequency in the population is remains unclear. The authors of the study are reviewing references on this subject, based on a case of extensive falx ossification. Manuscript describes the case of incidental detected of extensive calcification of the anterior brain sickle in a patient after head injury. Computed tomography revealed no pathology, but extensive ossification of falx was described. The patient did not complain of any significant complaints or neurological symptoms. The described calcification constituted a median and sagittal bone or calcium plate separating the frontal lobes of the brain. Analyzing references did not identify such extensive ossification of falx cerebri in human, however dural ossifications are reported in the references

Early prosthetic rehabilitation of a juvenile patient with hereditary ectodermal dysplasia – a case report

Ectodermal dysplasia is the term used to describe a large and heterogenic group of congenital disorders. Ectodermal dysplasia affects at least two ectoderm-derived structures. The dental abnormalities associated with ectodermal dysplasia are hipodontia, oligodontia and even anodontia. Aim of the study. The authors describe a clinical case of 5-yearold boy with hereditary hidrotic ectodermal dysplasia. Materials and methods. The first stage in the clinical treatment of a young patient affected by ectodermal dysplasia is presented. Complete dentures were made. Conclusion. Early prosthetic rehabilitation of juvenile patients with ectodermal dysplasia is a very complex problem. Early rehabilitation and an interdisciplinary approach are essential for successful treatment

Effect of the Lateral Bone Augmentation Procedure in Correcting Peri-Implant Bone Dehiscence Defects: A 7-Years Retrospective Study

Guided bone regeneration (GBR) is a well-documented and widely-used dental surgical procedure for the treatment of various types of alveolar bone defects. The aim of the study was to evaluate the long-term effectiveness of the GBR procedure in correcting small peri-implant bone dehiscence using the xenogeneic deproteinized bovine bone mineral material and a xenogeneic native bilayer collagen membrane. The present study was designed as a retrospective study. Seventy-five bone-level tapered two-piece dental implants Conelog®, Camlog (Biotechnologies AG, Switzerland) were divided into two groups G1—no bone augmentation (no GBR)—44 implants and G2—bone augmentation (GBR)—31 implants. For both groups, the closed healing protocol with a primary wound closure was used. The incidence of peri-implantits was evaluated, the quantitative assessment of soft tissue thickness was performed using the ultrasound (USG) device, quantitative assessment of marginal bone loss (MBL) was done. The prevalence of peri-implantitis was 5.3%, with a three-fold increase in peri-implantitis comparing the groups without and with bone augmentation (G1 = 2.27%, G2 = 9.7%). The average keratinized gingiva thickness was 1.87 mm and did not differ significantly between groups. No statistically significant differences in MBL between G1 and G2 were found. When dividing patients by gender, no statistically significant differences were observed. When dividing patients by age groups, statistically significant differences were observed between the youngest and oldest groups of patients. Within the limitations of this study, it can be concluded that the use of xenogeneic bone and a xenogeneic collagen membrane in a GBR procedure can be recommended to correct small peri-implant bone dehiscence

An Experimental Anodized and Low-Pressure Oxygen Plasma-Treated Titanium Dental Implant Surface—Preliminary Report

Chemical composition and physical parameters of the implant surface, such as roughness, regulate the cellular response leading to implant bone osseointegration. Possible implant surface modifications include anodization or the plasma electrolytic oxidation (PEO) treatment process that produces a thick and dense oxide coating superior to normal anodic oxidation. Experimental modifications with Plasma Electrolytic Oxidation (PEO) titanium and titanium alloy Ti6Al4V plates and PEO additionally treated with low-pressure oxygen plasma (PEO-S) were used in this study to evaluate their physical and chemical properties. Cytotoxicity of experimental titanium samples as well as cell adhesion to their surface were assessed using normal human dermal fibroblasts (NHDF) or L929 cell line. Moreover, the surface roughness, fractal dimension analysis, and texture analysis were calculated. Samples after surface treatment have substantially improved properties compared to the reference SLA (sandblasted and acid-etched) surface. The surface roughness (Sa) was 0.59–2.38 µm, and none of the tested surfaces had cytotoxic effect on NHDF and L929 cell lines. A greater cell growth of NHDF was observed on the tested PEO and PEO-S samples compared to reference SLA sample titanium

Active sport tourism in tourism and recreation course curriculum in the Academy of Physical Education in Katowice

Background. English language literature on tourism perceives active sport tourism, event sport tourism and nostalgia sport tourism as three forms of sport tourism. The primary aim of active sport tourism is travelling to participate in different sport activities, i.e. to be physically active. Active sport tourism is further divided into qualified, extreme and adventure tourism. Active sport tourism can be practiced in different environments, i.e. on land or water, as well as in the air, in summer and winter, and in the form of one-day, weekend- or multi-day trips. The paper presents the place of active sport tourism in the tourism and recreation course curriculum in the Academy of Physical Education in Katowice. Material and methods.

Phytochemical Diversity in Rhizomes of Three <i>Reynoutria</i> Species and their Antioxidant Activity Correlations Elucidated by LC-ESI-MS/MS Analysis

The rhizome of Reynoutria japonica is a well-known traditional herb (Hu zhang) used in East Asia to treat various inflammatory diseases, infections, skin diseases, scald, and hyperlipidemia. It is also one of the richest natural sources of resveratrol. Although, it has been recently included in the European Pharmacopoeia, in Europe it is still an untapped resource. Some of the therapeutic effects are likely to be influenced by its antioxidant properties and this in turn is frequently associated with a high stilbene content. However, compounds other than stilbenes may add to the total antioxidant capacity. Hence, the aim of this research was to examine rhizomes of R. japonica and the less studied but morphologically similar species, R. sachalinensis and R. x bohemica for their phytochemical composition and antioxidant activity and to clarify the relationship between the antioxidant activity and the components by statistical methods. HPLC/UV/ESI-MS studies of three Reynoutria species revealed 171 compounds, comprising stilbenes, carbohydrates, procyanidins, flavan-3-ols, anthraquinones, phenylpropanoids, lignin oligomers, hydroxycinnamic acids, naphthalenes and their derivatives. Our studies confirmed the presence of procyanidins with high degree of polymerization, up to decamers, in the rhizomes of R. japonica and provides new data on the presence of these compounds in other Reynoutria species. A procyanidin trimer digallate was described for the first time in, the studied plants. Moreover, we tentatively identified dianthrone glycosides new for these species and previously unrecorded phenylpropanoid disaccharide esters and hydroxycinnamic acid derivatives. Furthermore, compounds tentatively annotated as lignin oligomers were observed for the first time in the studied species. The rhizomes of all Reynoutria species exhibited strong antioxidant activity. Statistical analysis demonstrated that proanthocyanidins should be considered as important contributors to the total antioxidant capacity
