Lumbar disc herniation in children

Hernija diska lumbalne regije javlja se kod djece znatno rjeđe nego kod odraslih, a najčešće je zahvaćena razina L4-5. Naša bolesnica u dobi od 16 godina i 4 mjeseca hospitalizirana je zbog bolova u leđima i trnjenja u nogama unazad 2-3 godine. Pri neurološkom pregledu, tetivni refleksi su simetrični, a na nogama oslabljeni. Gruba mišićna snaga nogu je oslabljena. Lassequeov znak je obostrano pozitivan. Magnetskom rezonancom lumbosakralne kralježnice uočeno je suženje intvertebralnog prostora u segmentu L4-5, te fokalna dorzomedijalna protruzija intervertebralnog diska do 6 mm izvan koštanih okvira s kompresijom neuralnih struktura. Prisutan je i poremećaj senzibiliteta na nogama. Elektroneuromiografija pokazuje da se radi o kroničnoj neurogenoj leziji. Bolesnica je liječena konzervativno, uz djelomičnu regresiju tegoba. Hernija diska lumbalne kralježnice je entitet na koji je važno pomišljati i u dječjoj dobi, kako bi se pravovremeno provela odgovarajuća terapija i spriječile moguće komplikacije, te izbjegao invazivni način liječenja.Lumbar disc herniation occurs more likely in adults than in children, with the most common pathology site at L4-L5 lumbar level. Our patient was a 16 years and 4 months old girl with pain in her lumbar region and numbness in her legs that occurred two to three years ago. During the neurological examination, decreased, symmetrical tendon reflexes of the lower extremities were found. Muscle power in the legs was reduced with bilateral positive Lasseque’s sign. Magnetic resonance of lumbar spine showed narrowing of the intervertebral space at L4-L5 level with focal dorsomedial protrusion of the intervertebral disc within 6 mm outside of the bone frame and with neural structures compression. There was sensory impairment in the lower extremities. Electroneuromyography showed chronic neural lesion. The girl was treated conservatively, but with only partial response. Lumbar disc herniation is the entity that deserves more attention in children because early diagnosis provides adequate therapy and enables avoiding possible complications as well as invasive therapy

Forms of international movement of capital with special emphasis on the PPP and concessions

The state has always cooperated with the private sector in order to implement various activities in the best interest of public. The first models of public-private partnerships (PPP) appeared at the time of the Roman Empire in the context of public works in construction of public baths, markets and ports. Contemporary international movement of capital is a phenomenon that has existed for over a century. When discussing the PPP in modern day terms, the expansion of private involvement in the public sector starts in the 1970s and the 1980s of the previous century, in public infrastructure projects and in most developed economies. The primary purpose of these arrangements is to reduce expenditures in state budgets, but also to achieve faster and better execution of work, reduce risk and efficiently manage the projects. This paper will briefly present the evolution of PPPs and concessions, with an emphasis on understanding money and capital throughout the evolution of PPP, contemporary forms of movement of capital, as well as equity in terms of globalization. The subject of this paper are also examples of the important PPPs and concessions from the construction of the Suez Canal until today

Effects of Lactobacillus Reuteri Lozenges (Prodentis) as Adjunctive Therapeutic Agent in Non-Surgical Therapy of Periodontitis

Background/Aim: This study aimed to evaluate the effects of Lactobacillus reuteri lozenges as an adjunctive therapeutic agent in combination with scaling and root planing in a randomized, clinical trial of volunteers with periodontitis stage IV

Concentration of nitric oxide in patients’ saliva from various metal restorative activities in the oral cavity

Objective. Th e aim of this paper is to determine the concentration ofnitric oxide (NO) in the saliva of subjects resulting from the presence of various metal restorative activities in the oral cavity. Patients and methods. Th e research was conducted on 20 subjects (12 women and 8 men), aged 18-30, with no metal fillings in their oral cavity and 20 subjects (11 women and 9 men) aged 18-30 with prosthetic and conservative work in their oral cavities made of various metals. Th e pH of the saliva was established by means of an “Orion” type pH meter at an optimal temperature of 250C. Th e concentration of NO was determined by conversion of NO3-2 into NO2-2 with the help of elementary zinc and then by colorimetric testing of the NO2-2 concentration by means of the Griess reagent. Results. Our results established that the concentration of NO in patients with various metals (60.18±10.24) is 33.7% higher, which is statistically insignificant, in relation to the control group (45.01±6.28). Conclusion. Various metal restorative activities stemming from dentistry practice do not cause changes in the pH values of saliva and NO concentrations

Knowledge Assessment among the Fourth and Fifth Year Students on the Potentially Malignant Lesions of Oral Cavity

Background/Aim: Potentially malignant oral lesions (PMOL) are lesions that have an increased risk of malignant transformation concerning healthy oral mucosa. This research aimed to assess the knowledge of students of final years of study on the potentially malignant lesions of the oral cavity

Economics of Digital Transformation

The papers published in this monograph present best papers presented at the first conference of the Faculty of Economics and Bussiness of University of Rijeka organized on the topic of “Economics of digital transformation” from 2nd to 4th of May, 2018 in Opatija, Croatia (www.edt- conference.com). During the three days of the conference more than 50 researchers from European region contributed with their presentations. We are particularly proud on the results of our doctoral workshop where nine young researchers presented their research while five papers were published in the monograph. In this way we are building our future research capacities and expose young researchers to rigorous scientific challenge
