Abstract
Surface modification of textile fabrics and leathers is very versatile and allows the products quality improvement. In this work, cotton and leather substrates were pre-treated with cold atmospheric pressure plasma (CAPP) and further coated with TiO2-SiO2-reduced graphene oxide composites in dispersion form. By using a Taguchi scheme, this research evaluated the effect of three significant parameters, i.e., the pre-treatment with CAPP, organic dispersion coating and TiO2-SiO2-reduced graphene oxide (TS/GR) composites, that may affect the morpho-structural properties and photocatalytic activity of modified cotton and leather surfaces. The characteristics of cotton/leather surfaces were evaluated by morphological, structural, optical and self-cleaning ability using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM/EDX), X-ray powder diffraction (XRD), attenuated total reflection-Fourier Transform Infrared spectroscopy (ATR-FTIR) and UV-Vis spectroscopy. The self-cleaning performance of the obtained cotton and leather samples was evaluated by photocatalytic discoloration of berry juice surface stains under UV light irradiation for 12 h. The successfulness of coating formulations was proven by the SEM analysis and UV-Vis spectroscopy. The XRD patterns and ATR-FTIR spectra revealed the cellulose and collagen structures as dominant components of cotton and leather substrates. The CAPP treatment did not damage the cotton and leather structures. The photocatalytic results highlighted the potential of TiO2-SiO2-reduced graphene oxide composites in organic dispersion media, as coating formulations, for further use in the fabrication of innovative self-cleaning photocatalytic cotton and leather products.

Abstract
Easy and cost-efficient modifications of titanium dioxide nanoparticles that improve their efficiency in the visible light domain represent a continuous and challenging research topic. In addition, the effect of graphene on the overall photocatalytic process is still debated. Consequently, herein, we prepared a series of TiO2 nanoparticle-based composites with different copper oxide mass content (1–3%) and co-doped with graphene of different oxidation degrees. Different characterization techniques were used to analyze the structural and physico-chemical properties of the obtained composites: Scanning Electron Microscopy (SEM)/Transmission Electron Microscopy (TEM)/Energy-dispersive X-ray spectroscopy (EDX) analysis, X-ray powder diffraction (XRD), Fourier-transformed infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The photocatalytic performance was evaluated by the degradation of methylene blue under both UVA and visible light irradiation. The nanocomposites show very good photocatalytic activity independent of the presence of reduced graphene oxide, due to the Cu2O/CuO-TiO2 heterojunctions. This finding has been confirmed by the very efficient visible-light-driven degradation of amoxicillin and ciprofloxacin.

Abstract
INTRODUCTION A comparative clinical study has been conducted on patients involved using lateral intersomatic arthrodesis for the treatment of adjacent segment disease using titanium and PEEK intersomatic devices. MATERIAL AND METHODS Clinical (EVA and oswestry disability index ODI) and radiological (alignment and fusion), complications (major and minor) and quality of life (EQ5D) of 32 patients intervened from September 2015 to September 2018 have been analyzed and compared, with an average follow-up of 25 months (46-18). The average age in surgery was 66 years (39-89) and 68% of patients were women. RESULTS The most common segment involved was L3-L4 (62%) right retroperitoneal approach 86%. Lumbar EVA improved from 6.2 ± 2.12 to 4.1 ± 1.71 (p = 0.028). The LEG EVA descended from 5.3 ± 2.26 to 1.9 ± 1.58 (p = 0.02). The ODI scales improved from 50.2 ± 18.9 to 33.3 ± 10.2 (p = 0.025) and the EQ5D went from 0.52 to 0.73 (p = 0.039) with no statistically significant differences between the groups (ODI p = 0.18, EQ5D p = 0.293). Radiologically increased intervertebral height, lumbar and segmental lordosis, decreased Cobb's angle and the overall melting rate was 84.3% (88% Ti/82% PEEK), with no differences between the groups. CONCLUSION Lateral lumbar interbody fusion is an effective method for treating adjacent segment disease with clinical-radiological results and literature-like complications. No differences have been found between Ti and PEEK implants.

Abstract
The irreducible dislocation of the hallux interphalangeal joint is an infrequent condition and only a few cases have been described. It presents as dorsal dislocation with interposition of the sesamoid bone, which has the possibility of being radiologically undetectable. We present the case of a 29 year-old patient who, after a sports trauma sustained a hallux interphalangeal dislocation that went unnoticed for eight days. Since, closed reduction was not possible, as occurred in several cases reported in the literature, open reduction was performed through a dorsal incision. Based on a bibliographic review, it is possible to state that there are several treatment options and multiple approaches, and that these lesions usually have a good prognosis.

Abstract
BACKGROUND Hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) can affect children, with the mechanism proposed being inhibition of the cyclooxygenase enzyme-1 (COX-1). In these patients nonchemically related NSAIDs, including COX-2 inhibitors, can induce the reaction, hampering treatment of fever and inflammatory processes. OBJECTIVES To analyse retrospectively tolerance to etoricoxib, a selective COX-2 inhibitor, and to meloxicam, a preferential COX-2 inhibitor, in children with hypersensitivity to NSAIDs. METHODS Clinical records of children (aged 1-14 years) diagnosed with hypersensitivity reactions to NSAIDs from January 2006 to January 2013 were included. The diagnosis was confirmed by oral drug provocation test (DPT) with the culprit NSAIDs and acetylsalicylic acid (ASA). Tolerance to paracetamol, etoricoxib and meloxicam was also evaluated. RESULTS The study included 41 children with a positive DPT with ASA and the culprit NSAID. DPT with paracetamol and etoricoxib was negative in all children, although two (4.9%) children developed a reaction after the administration of meloxicam. CONCLUSIONS These data indicate that both etoricoxib and meloxicam are good alternatives for treatment in older children with hypersensitivity to NSAIDs.

Abstract
INTRODUCTION The idea of establishing an examination that accredits the training of the specialists in orthopaedic surgery at the end of their educational period as residents is subject to controversy. With the aim of encouraging the development of this examination, the present members of the National Commission of the Specialty of Orthopaedics (CNE) have reviewed the results obtained in previous examination. MATERIALS AND METHODS The results of the voluntary final exam for Orthopaedics residents, and of the surveys of participant opinions for the years 2006 to 2011 are presented. RESULTS The total number of participants was 231, growing from 19 in 2005, to 71 in 2011. The overall mean score in the period reviewed (2006-2011) was 6.72 out of 10 points. In these 6 years, 9 participants failed (4.25%). The mean score for the test was 7.57. The overall mean score of the oral exam was 6.57. The worst results were obtained in the general knowledge section of the oral examination. Nobody has ever failed the section on reconstruction of the lower extremity. The upper extremity section in the oral examination achieves the best average results. DISCUSSION The examination has established its place in the structure of orthopaedic resident training in our country, even without making it official by the Administration. We must positively acknowledge those candidates who chose to take the examination and be evaluated by their peers in order to prove their qualification and distinction. This recognition will be the best encouragement for future generations.

Abstract
Carney's triad is defined by the coexistence of at least two of three rare disorders, including gastric epithelioid leiomyosarcoma (malignant leiomyoblastoma), pulmonary chondroma, and paraganglioma, most often extra-adrenal and functioning. We report a new case in a 10-year-old girl. The paraganglioma, although nonfunctioning, was detected after it was searched for, as Carney's triad was suspected. Unrelated seems the development of breast fibroadenomas in the same patient. Whenever a patient with one component of the triad is encountered, the possibility of this syndrome should be considered and the other two components sought.
