The introduction of resection prostheses paved the way for the development of limb-sparing surgery in patients with primary or metastatic bone tumours. After some time, the developing possibilities of treatment of extensive bone defects allowed for the use of resection prostheses as an emergency procedure in patients undergoing revision surgery due to hip implant loosening. The aim of this paper is to compare treatment outcomes in patients receiving the Modular Universal Tumour and Revision System (MUTARS) resection prosthesis during arthroplasty performed for different indications: treatment of a tumour metastasis and revision surgery in cases of implant loosening. Material and methods. A total of 34 MUTARS femoral resection prostheses were implanted in 34 patients at the Cracow Centre of Rehabilitation and Orthopaedics between December 2008 and January 2016. The procedure was indicated due to the presence of a tumour metastasis (in 13 cases) or due to implant looseni...

W dużej liczbie przypadków nieuchronnie znajdują się pacjenci, u których mimo pierwotnego charakteru zabiegu niezbędne jest uzupełnienie ubytków kostnych panewki stawu biodrowego. Stosowane w tych przypadkach przeszczepy kostne auto-i alogenne oraz pierścienie oporowe wymagają długiego odciążania, aby umożliwić wgojenie przeszczepów. Częściowo wady tej pozbawione są wypełnienia wykonane z porowatego tytanu. Celem pracy jest przedstawienie naszych wyników zastosowania uzupełnień z porowatego tytanu w aloplastykach pierwotnych. Materiał i metody. Do badania włączono grupę 23 chorych (18 kobiet i 5 mężczyzn), którym w latach 2010-2015 w Krakowskim Centrum Rehabilitacji i Ortopedii w czasie pierwotnej aloplastyki stawu biodrowego wszczepiono implant z porowatego tytanu. Wyniki. W średnim okresie obserwacji zanotowano poprawę w zmodyfikowanej i tradycyjnej skali Harris'a oraz redukcję dolegliwości bólowych w skali VAS. Nie zanotowano obluzowania ani infekcji implantu. Zastosowanie porowatego tytanu pozwoliło zmniejszyć liczbę koniecznych do użycia przeszczepów kostnych. Wnioski. 1.Uzupełnienie ubytków panewki implantami z porowatego tytanu może być stosowane w aloplastykach pierwotnych stawu biodrowego z dobrym wynikiem klinicznym i radiologicznym. 2. Zastosowanie uzupełnień z porowatego tytanu pozwala zmniejszyć liczbę przeszczepów kostnych niezbędnych do uzupełnienia ubytków panewki i pozwala na natychmiastowe, częściowe obciążanie kończyny. Słowa kluczowe: porowaty tytan, całkowita aloplastyka stawu biodrowego, ubytek panewki SUMMARY Background. Total hip arthroplasty is an increasingly common procedure. The large number of cases inevitably includes patients who require filling of their acetabular defect even in their primary surgery. The use of a utogenous grafts and allografts as well as resistance rings requires patients to avoid loading the limb for a long time to enable implant integration. This disadvantage may be partially eliminated by using trabecular titanium implants. The aim of this paper is to present the outcomes of the use of trabecular titanium implants in primary hip arthroplasty. Material and methods. The study embraced 23 patients (18 women and 5 men) whose primary hip arthroplasty was performed in the Cracow Centre of Rehabilitation and Orthopaedics in the period 2010-2015 and involved placement of a trabecular titanium implant. Results. Medium-term follow-up revealed improvement according to the modified and traditional Harris Hip Score and reduction in pain according to VAS. Loosening of the implant or infection were not recorded. The use of trabecular titanium allowed for reducing the amount of bone grafts used. Conclusions. 1. Reconstruction of acetabular defects with trabecular titanium implants may be used in primary hip arthroplasty to produce good clinical and radiographic outcomes. 2. The use of trabecular titanium implants allows for reducing the amount of bone grafts necessary to fill the acetabular defect and enables immediate partial loading of the limb.

We studied whether potent vasodilators hydrogen sulfide (H2S) and carbon monoxide (CO) can protect against alendronate-induced gastric lesions in rats exposed to mild stress. Three series (A, B, and C) of Wistar rats received alendronate (150-700 mg/kg i.g., series A) with or without NaHS (5 mg/kg), H2S donor or CORM-2 (5 mg/kg) releasing CO administered i.g. 30 min before alendronate administration (series B) in rats exposed for 3 days before alendronate administration to mild stress (series C). The area of gastric lesions was assessed by planimetry, the gastric blood flow (GBF) was determined by H2-gas clearance technique, and H2S production via CSE/CBS/3-MST activity and the gastric expression of HO-1, HO-2, HIF-1α, NF-κB, iNOS, COX-2, IL-1β, TNF-α, GPx-1 and SOD-2 were analyzed by qPCR or Western blot.

Previous studies including those from our laboratory have revealed that their gastroprotective effect results from cooperation with other factors responsible for protection of the gastric mucosa, including prostaglandin (PG) synthesis pathway, nitric oxide (NO) and the sensory afferent fibres releasing the vasoactive neurotransmitters. The aim of the present study was to determine whether ghrelin, orexin-A (OX-A) or nesfatin-1 with their protective effect on the gastric mucosa, also can modify the healing of chronic gastric ulcers. Furthermore, an attempt was made to explain participation of these peptides in healing processes of chronic gastric ulcers with comorbid conditions for the human beings resulted from diabetes mellitus. In our study, a model of gastri...

Advanced haemophilic arthropathy is a possible complication in patients with congenital bleeding disor­ders. This study aimed to assess treatment outcomes after primary total knee arthroplasty in this group of patients. Material and methods. A total of 60 primary total knee arthroplasties were performed in the period 2011-2014. The study ultimately included 40 knee replacements in 35 patients. The average follow-up period was 19.4 months (max. 32, min. 12), with patients followed up for a period shorter than 12 months excluded from the study. The average age of the patients was 36.7 years (min. 27, max. 72). Types of inherited bleeding disor­ders among the study population were as fol­lows: 82% with haemophilia A, 15% with haemophilia B and 1% with Von Willebrand disease. Pain intensity was assessed before the surgery and at a 12-month follow-up visit using VAS. The patients completed the OKS and WOMAC question­naires before the surgery and at the 12-month follow-up visi...

Intestinal microbiota can potentially cause damage to the mucosa either directly by releasing toxins or indirectly by causing a detrimental immune response. Probiotic bacteria have been defined as live microorganisms, which when consumed in adequate amounts, confer a health benefit for the host. In recent years, the therapeutic and preventive application of probiotics for several gastrointestinal and liver disorders has received increasing attention. Probiotics appear to be beneficial for premature infants who suffer necrotizing enterocolitis. The effectiveness of certain probiotics as treatment for infectious and antibioticassociated diarrhea in adults and for allergic disorders in children has been supported by clinical studies; however, the potential mechanism( s) remains to be studied. Experimental studies and clinical trials for probiotic treatment of inflammatory bowel diseases (IBD) have yielded conflicting results. Daily intake of selected probiotics was effective in the prevention of ulcerative colitis and the attenuation of the active onset of Crohn's disease or ulcerative colitis but others failed to show a beneficial effect. The combination of Lactobacillus, Bifidobacterium, Saccharomyces boulardi and the treatment with Escherichia coli Nissle were found beneficial in inducing and maintaining remission of disease activity of gut inflammation and moderately severe ulcerative colitis. Probiotic bacteria were considered in some studies as a safe adjuvant when added to triple eradication therapy against the symptoms induced by the major gastric pathogen, Helicobacter pylori. This review attempted to overview these new exciting advances in the role of these microbes in the pathogenesis, management and treatment of gastrointestinal disorders.
