Authors: Alzyoud Sukaina , Boukerdenna Hala , Abbadi Ahmad , Weglicki Linda S.
Published: May 2021

BACKGROUND: Article 11 of WHO-FCTC strategies emphasize the need for countries to include health warnings on packages of tobacco products. This study aims to assess Jordanian people, aged 13 years and above knowledge and beliefs about the inclusion of health warning labels on waterpipe tobacco packages.

METHODS: A descriptive cross-sectional approach was conducted among youth and adults aged 13 years and above. The sample was recruited from public schools, universities, and a governmental public service agency. Data collection was done through an electronic survey using Tablets.

RESULTS: A total of 1067 participated in the study, with ages ranging between 13– 63 years old with a mean (20.9, SD= ± 6.1). Study participants mainly consisted of students making (86.7%) of the total sample. These students were in secondary education school (19.3%) or attending university (67.4%). Findings indicated that participants tobacco smoking status were non-smokers, single type smoker, dual smoker, and triple smokers (67.8%, 21.6%, 6.8%, and 3.7% respectively). In comparison the prevalence of smoking single tobacco type, dual smoking, and triple smokers tobacco products was statistically higher among males than females (11.1%-10.6%, 5.1%-1.8%, and 3.1%-0.7% respectively). Eighty-seven percent knew that waterpipe smoking is harmful and would support the inclusion of health warnings on the tobacco packet. Thirty percent indicated that the inclusion of health warnings will greatly improve their knowledge of the harmful effects of tobacco smoking.

CONCLUSION: The current study shows that participants believe including health warnings on waterpipe tobacco package would help smokers to think about quitting.

Authors: Jakubowski Krzysztof
Published: May 2021

A fire alarm system (FAS) is one of the most important safety facilities used in any building, and include CCTV and intrusion and panic alarms. Pursuant to the Polish Regulation of the Minister of the Interior and Administration of 07/06/2010, FASs are required in specific civil structures. FASs are directly responsible for the protection of the life and health of humans and animals, and indi-rectly for property at the protected sites. In considering the fire hazards and scenarios, a FAS should be characterized with sufficient reliability. Every FAS is subject to specific requirements in terms of reliability and continuity of performance at the stages of monitoring, FAS failure, and fire. This work is an analysis of the reliability requirements for FAS. Keywords: fire alarm system, reliability requirements, structures.
Su-22 and MiG-29 aircraft as air-launch platforms for space rockets
Authors: Olejnik Aleksander , Zalewski Piotr
Published: May 2021

The work is an announcement on the current state of the research project implementation. The study presents the results of an analysis of the project’s research area. On this basis, the two-stage micro-satellite launch system was selected. The system, a space-kit is based on an adopted combat aircraft carrying a satellite-laden rocket that is fired at the maximum altitude. As a potential transport platform, two withdrawn supersonic aircraft were selected: the MiG-29 and the Su-22. A dedicated mission-laden rocket is to be carried under the fuselage. Preliminary analyses have shown that the aircraft indicated with the proposed mission profile will successfully carry out the task of launching a hypothetical rocket with a payload of at least 10 kg into low earth orbit. This confirmed the merits of the basic thesis of the research project. For the analysis of the aeromechanical properties of the kit, both 3D digital models for computer simulations and physical models scaled for tunnel tests were developed. Laser scanners were used to map aircraft geometry, and measurements were made on Su-22 and MiG-29 aircraft in the aviation laboratory of the Military University of Technology. Using three-dimensional scaled models generated in a CAD environment, physical solid models were printed for wind tunnel investigations. Preliminary computer simulations conducted in the ANSYS Fluent system did not point out any negative impact of the rocket on aerodynamic characteristics and stability of the both carrier aircraft. Keywords: air-launch satellite system, air-launch platform, microsatellite.

Authors: Karadža-Lapić Ljerka , Pikivaca Tamara , Pervan Petra , Jović Zlatović Josipa , Delin Sanja , Prkačin Ingrid
Published: May 2021

Objective. Angioedema (AE) is a potentially life-threatening event. We investigated the etiology of AE, with the emphasis on bradykinininduced angioedema treatment in emergency medicine.

Methods. The retrospective study included 237 patients with AE, who were examined and treated in two hospitals (group A and B) in Croatia from 2009 to 2016. The location and duration of AE, data about chronic diseases and treatment, potential causative agents (food, drugs, insect bites and chemicals), physical examination data and the subsequent treatment were analyzed.

Results. There was no statistical difference regarding age or comorbidities but there was a statistically significant difference in etiology between the groups (Chi-square, P=0.03). Renin-angiotensin-aldosterone system (RAAS) blocker induced AE was the main cause of emergency attendance in group A (37.5%) and among the leading causes in group B (18.8%). Bradykinin-induced AE (hereditary angioedema (HAE) and RAAS-AE) were the leading causes in a total of 75 (31.5%) patients. RAAS-AE was treated with glucocorticoids and antihistamines. HAE attacks in both groups (2/7 patients, 1.5/6%) were treated with specific therapy. Other causes of AE in groups A/B were insect bites (15/23 patients, 13.5/20%), use of antibiotics/analgetics (11/17 patients, 9/15%), gastroesophageal reflux disease (10/11 patients, 8/9%), neoplasms (5/6 patients, 4/5%) and idiopatic (32/31 patients, 26.5/26%). 21% of patients were hospitalized.

Conclusion. Bradykinin-mediated AE was the main cause of emergency attendance associated with AE. Advances in the treatment of HAE, with case reports of patients with RAAS-AE treated with C1 esterase inhibitor concentrate or bradykinin receptor antagonist, may prove to be a new, reliable and efficacious therapy option.

Objective of the paper is to present lung cancer as preventable disease based on epidemiological, molecular and genomic data. Lung cancer is the most deadly malignancy around the world, both in male and female population. Vast majority of lung cancers (close to 90%) are directly caused by cigarette smoking, and thus present one of the most preventable deadly disease in humanity. Analysis of history of cigarette consumption and rise of lung cancer as world epidemics. Review of efforts to fight tobacco epidemics and how it influences incidence and prevalence of the lung cancer. Investigation of the effects of cigarette smoking on health and economic status of Bosnia and Hercegovina. Tobacco epidemics and lung cancer can be prevented. Goal is to exterminate cigarette smoking. That can be achieved only concerted effort by members of family, patients themselves, physicians, researchers, non-governmental organizations, political figures and society as a whole.

Conclusion. In country like Bosnia and Herzegovina first step is to inform society about devastating effects of cigarette smoking. Best practices already exist and initial goal should be to start using them.
The English Sweating Sickness: Out of Sight, Out of Mind?
Authors: Heyman Paul , Cochez Christel , Hukić Mirsada
Published: May 2021

In this paper we aim to add additional knowledge regarding the occurrence, origin and epidemiological features of the English sweating sickness. The English sweating sickness raged in five devastating epidemics with mortality rates between 30 and 50% between 1485 and 1551 throughout England, and on one occasion also affected mainland Europe, in 1529. The Picardy sweat, generally considered as the English sweating sickness’ lesser deadly successor, flared up in France in 1718 and caused 196 localized outbreaks with varying severity all over France and neighboring countries up to 1861. The English sweating sickness has been the subject of numerous attempts to define its origin, but so far all efforts have failed due to lack of material, DNA or RNA, that - using modern techniques and knowledge - could shed light on its cause. Although the time frame in which the English sweating sickness occurred and the geographical spread of the outbreaks is generally known, we will demonstrate here that there was more to it than meets the eye. We found reports of cases of sweating sickness in years before, after and between the 1485, 1508, 1517, 1529 and 1551 epidemics, as well as reports of sweating sickness in Italy and Spain.

Conclusion. In spite of the fact that the English sweating sickness apparently has not caused casualties for a more than a century now, we suggest that -given the right circumstances- the possibility of re-emergence might still exist. The fact that up until today we have no indication concerning the causal pathogen of the English sweating sickness is certainly not re-assuring.
Lung Cancer Genomics
Authors: Parikh Ankur R.
Published: May 2021

The landscape of lung cancer treatment is rapidly evolving with the use of genomic testing which helps identify specific mutations or resistance mutations for these heterogenous tumors. Advanced lung cancer has a very poor prognosis but identifying other treatment options based on genomic profiling of the tumor can lead to improved outcomes. Evidence of benefit for genomic testing in lung cancer has now resulted in this test becoming part of national guidelines. There are challenges with genomic testing which need to be understood as well as understanding how to apply test results. These results can help identify treatment options or may serve as predictors to respond to specific therapies.

Conclusion. In the current era of precision medicine, it is imperative clinicians be familiar with genomic testing and be able to offer it to their cancer patients, specifically those with advanced lung cancer.

Objective. Lysozyme is a natural antimicrobial and immunomodulatory enzyme, which is produced as a host response to infectious agents. The objective of this study was to compare the efficacy and safety of lysozyme-based versus benzydamine and chlorhexidinebased oral spray in patients with an acute tonsillopharyngitis associated with a common cold.

Patients and Methods. A prospective twoarm pilot study (lysozyme/cetylpyridinium/lidocaine spray versus: benzydamine spray—arm 1; chlorhexidine/lidocaine spray—arm 2) was conducted in the primary health care unit. Efficacy was evaluated by the patient’s self-assessment of pain, difficulty in swallowing and the throat swelling, by using the visual analog scale (VAS) at baseline and three follow-up visits. Safety was evaluated by the assessment of the frequency and severity of adverse effects.

Results. Lysozyme-based spray reduced pain faster than benzydamine-based spray and slower than chlorhexidine-based spray. Lysozyme-based and chlorhexidinebased sprays similarly reduced difficulty in swallowing, but were faster than benzydamine-based spray. Similar effects on the reduction of throat swelling were seen in all treated groups. All tested products showed proper safety and were well tolerated, with no serious adverse events reported.

Conclusions. The lysozyme-based oral spray was shown to be effective and safe in the reduction of pain, difficulty in swallowing and throat swelling in patients with acute tonsillopharyngitis associated with a common cold. Lysozyme-based oral spray (containing natural compound with advantages of influencing immune system and preventing recurrences) had similar activity to benzydamine and chlorhexidine-based oral antiseptic sprays.

Authors: Esparza Melissa , Wild Jason R. , Minnock Christopher , Mohty Kurt M. , Truchan Lisa M. , Taljanovic Mihra S.
Published: May 2021

Objective. To determine the effectiveness of diagnostic ultrasound (US) at evaluating the condition of the radial nerve in the setting of humeral shaft fractures.

Materials and Methods. An observational study was performed of 18 patients with radial nerve palsy associated with humeral shaft fractures who underwent US examination to assess the condition of the radial nerve.

Results. Six patients with humeral shaft fractures treated nonoperatively in a functional brace had US findings consistent with contusion or stretch radial nerve injury. Twelve patients ultimately underwent surgery either because US showed an entrapped or lacerated radial nerve, or for other operative indications. There was a 92% concordance (11/12 patients) between US and intraoperative findings with regards to the condition and location of the radial nerve, with the remaining case being complicated by delayed surgical treatment secondary to patient factors.

Conclusion. Our study demonstrates that US is an effective diagnostic tool in evaluating radial nerve injuries in the setting of humeral shaft fractures and can aid in clinical decision making by differentiating between patients with nerve laceration or entrapment who may benefit from surgery from those with neurapraxia managed nonoperatively.

Authors: Tarkowski Eric M. , Omar Imran M. , Blount Kevin J. , Gryzlo Stephen M.
Published: May 2021

Objective. Acute inferior subscapularis myotendinous junction injuries are occasionally seen in overhead throwing athletes, and can present with posterior shoulder pain.

Case Reports. Four professional baseball pitchers presented with acute onset of posterior shoulder pain while pitching. After thorough, routine physical examination of the shoulder by the referring orthopaedic surgeon magnetic resonance imaging (MRI) was performed within 7-10 days of the onset of presenting symptoms and interpreted in consensus by 2 fellowshiptrained musculoskeletal radiologists with 9 and 5 years of experience and a musculoskeletal radiology fellow. The patients were then treated conservatively for subscapularis musculotendinous injuries and clinically assessed for symptom resolution before they were allowed to return to play.

Conclusion. Inferior subscapularis myotendinous junction injuries should be included in the differential diagnosis of baseball pitchers with posterior shoulder pain.
Systemic and Inhaled Corticosteroids, with or without Beta Agonists, as Adjuvant Therapy in Community Acquired Pneumonia
Authors: Helgeson Scott A. , Levitt Joseph E. , Festic Emir
Published: May 2021

The aim is to provide a narrative review of the role of corticosteroids, with and without inhaled beta agonist, in communityacquired pneumonia. Community and health-care associated pneumonia remain leading causes of morbidity and mortality despite appropriate antibiotic therapy. The pneumonia-associated adverse outcomes are not only related to the infectious organism, but also to a dysfunctional host-immune response resulting in overwhelming inflammation. Use of systemic corticosteroids as adjuvant therapy in pneumonia remains controversial. Multiple randomized clinical trials evaluating corticosteroids in patients with community acquired pneumonia have found discrepant results in terms of benefits and adverse effects. Inhaled delivery of corticosteroids offer the potential advantage of providing therapeutic benefits directly to the lung, with minimal to no adverse systemic effects.

Conclusion. Although meta-analyses suggest potential benefits in a select group of patients with more severe pneumonia, the ideal timing, dose, route of delivery, duration, and patient selection remain to be established. A smaller body of literature suggests benefit of inhaled corticosteroids, with or without inhaled beta agonists, but future large scale clinical trials are needed to establish clinical benefit with inhaled delivery.

Authors: Chrysikos Dimosthenis , Athanasopoulos Andreas , Georgakopoulos Panagiotis , Antonopoulos Ioannis , Samolis Alexandros , Troupis Theodore
Published: May 2021

Objective. The aim of our paper is to depict an anatomical variation of the brachial plexus, concerning a communicating branch between the median and the musculocutaneous nerve and its clinical significance. Anatomical variations of the brachial plexus and especially those of the musculocutaneous nerve are quite common. Awareness of these variations is of paramount importance in clinical practice, mainly in achieving best results in minimal invasive or surgical procedures.

Case Report. After dissection in upper extremities in a 89-year-old male cadaver, a communicating branch between the median and the musculocutaneous nerve was found. This communicating branch was formed before the musculocutaneous nerve perforated the coracobrachialis muscle. It also derived from the level of the ansa medianis and its course was of an approximately 2cm length.

Conclusion. The clinical significance of our study is the entrapment of the musculocutaneous nerve that may cause clinical findings similar to those of the carpal tunnel syndrome.

Published: May 2021

Objective. Tumors of the brain and spine make up about 20% of all childhood cancers; they are the second most common form of childhood cancer after leukemia. Brain tumors are the most common solid tumor in children. Symptoms depend on a variety of factors, including location of the tumor, age of child, and rate of tumor growth. The aim of study was to present our experience with the diagnosis and treatment of brain tumors in children.

Patients and Methods. The aim of this study is to analyze clinicopathological characteristics, treatments, complications, and outcomes in children with brain tumors. This study is a retrospective analysis of 27 consecutive patients younger than 16 years and hospitalized for surgical treatment of brain tumors. Intracranial hypertension, neurological status, radiological computerized tomography (CT) or magnetic resonance imaging (MRI) findings, tumor localization, type of resection, hydrocephalus treatment, histopathology, complications, and outcome were analyzed.

Results. Twenty-seven surgeries were performed in patients for brain tumors. There were 9 females and 18 males. The average patient age was 7.8 years. There were 11 (40%) children with astrocytoma; of these, there were 9 (82%) pilocytic astrocytomas and 2 (18%) ordinary histopathological subtypes of high-grade tumors.

Conclusion. As with any cancer, prognosis and long-term survival vary greatly from child to child. Prompt medical attention and aggressive therapy are important for the best prognosis. Continuous follow-up care is essential for a child diagnosed with a brain tumor.

Published: May 2021

Objective. Our main objectives were to analyze and determine the safety, risk of post-operative complications, and surgical outcome of the endoscopic endonasal approach to the clival region.

Methods. From May 2011 to May 2019, we operated on 19 patients using the endoscopic endonasal approach to the clival region. Their pathologies were diverse: pituitary macroadenoma, craniopharyngioma, metastasis, and a prepontine neurenteric cyst. The first operations were supervised by an experienced center using telementoring. We explained our surgical technique and analyzed the patients’ data, which were included in our study.

Results. We managed to achieve complete removal of the pathological process in 14 patients. There were no deaths in the perioperative and early post-operative period. The most common complication was a cerebrospinal fluid leak, which was successfully managed in all of the cases. There were no deaths or significant morbidities in the post-operative period.

Conclusion. An endoscopic transnasal approach to the clival region is safe and effective. It provides better visualization of that region compared to other transcranial approaches. The risk of post-operative complications is significantly lower with the help of modern reconstructive techniques. CSF leak is the most frequent complication.
Peripheral Nerve Tumors as an Ongoing Challenge in Neuro-oncology: An Overview of Their Biological and Technical Nuances
Authors: Matić Siniša , Lepić Milan , Kovačević Vojin , Grujić Jovan , Vitošević Filip , Savić Andrija , Rasulić Lukas
Published: May 2021

This paper aims to provide an overview of recent advances in the diagnosis and treatment of peripheral nerve tumors (PNTs) with regard to biological and technological nuances, and to highlight some recommendations for achieving better outcomes in the treatment of patients suffering from PNT. PNTs are probably the most challenging entity in the field of peripheral nervous system surgery. The goal of removing a nerve tumor while also preserving nerve function at the same time is often complicated, regardless of the surgeon’s experience. Still, in most cases, high-quality results can be achieved upon carefully planned surgery. Clinical presentation, diagnosis, and indications for a specific type of treatment of PNTs still remain a topic of debate. Recent technological advances have led to an exponential improvement in the field with utilization of intraoperative ultrasound, neurostimulation devices, and intraoperative electrophysiological monitoring, along with the development of modern surgical techniques, whereby a multidisciplinary and individually shaped approach is necessary.

Conclusion. These advances, however, still remain limited, and recent research is focused on the development of biological therapy. Biologically targeted therapies will emerge when there is a better understanding of the genetic and molecular mechanisms driving the development and growth of PNTs.

Authors: Cazic Dejan , Marosevic Goran
Published: May 2021

Objective. The aim of this study was to investigate adverse effects, progression free survival (PFS), one-year local control (LC) and one-year overall survival (OS) of patients with liver oligometastases treated with stereotactic body radiotherapy (SBRT), and whether there was a significant difference in these parameters in patients with primary colorectal cancer compared to other tumor localizations.

 Patients and Methods. Patients were simulated using four-dimensional computed tomography (4DCT). Using volumetric modulated arc therapy (VMAT) technique, SBRT was performed on 16 patients with <3 liver metastases. The prescribed dose was 60 Gy in 8 fractions (BED 105 Gy). Cone beam CT (CBCT) was used for image guidance before each frac­tion with online correction.

Results. There were no adverse effects. Median PFS for all patients, patients with primary colorectal cancer, and patients with primary non-colorectal cancer was 11 months (SE 2.1), 16 months (SE 2.8), 6 months (SE 2.4), re­spectively. There was no significant difference in the PFS for these two observed groups (P=0.09). The one-year LC was 62.5%. Patients with primary colorectal cancer had one-year LC of 87.5%, while the group of patients with primary non-colorectal cancer had one-year LC of 37.5% (P=0.063). The total one-year OS was 87.5%. In the group of patients with primary colorectal cancer, the one-year OS was 100%, while in the group of patients with primary non-colorectal cancer, the one-year OS was 75% (P=0.317).

Conclusion. SBRT with 8 × 7.5 Gy can be safely delivered and is effective method of treating liver oligometastases.

Authors: Kopanaki Evangelia , Piagkou Maria , Demesticha Theano , Anastassiou Emmanouil , Skandalakis Panagiotis
Published: May 2021

Objective. The aim of the present preliminary study was to assess whether the sternomental distance ratio (SMDR) could be suitable as a predictor of difficult laryngoscopy, in both normal surgical patients and patients scheduled to undergo thyroid tumor surgery.

Methods. Two hundred and twenty-one consecutive adult patients (among them 122 patients with presumed normal airways and 33 patients with thyroid tumors), scheduled to undergo elective surgery under general anesthesia, were included in this study. Physical and airway characteristics, SMDR, difficult laryngoscopy (using Cormack-Lehane scale) and any kind of assisted intubation were assessed.

Results. Decreased SMDR demonstrated a strong correlation with difficult laryn­goscopy in both thyroid tumor (Kendall’s tau-b -0.578 (P=0.004) and normal patients -0.362 (P<0.001). Difficult laryngoscopy was 0 at SMDR>1.9 and 33% at SMDR <1.55 (P<0.001). The higher the SMDR was, the better the glottic view obtained.

Conclu­sions. Α SMDR>1.9 indicates an easy laryngoscopy, whereas SMDR <1.55 indicates a difficult one in both thyroid tumor and normal patients. SMDR is an objective test to assess difficult airway in thyroid surgery.

Authors: Grivas Grigoris , Lagousi Theano , Mandilara Georgia
Published: May 2021

Objective. This study aimed to describe Salmonella epidemiology and antimicrobial resistance in Greek children over the pe­riod of 2011-2017.

Materials and Methods. A 7-year retrospective study (2011-2017) was performed, based on data recorded by the National Reference Centre for Salmonella, among children aged ≤14 years. Epidemiological data, serovar distribution and antimicrobial resistance patterns were recorded.

Results. Overall, 2347 Salmonella isolates were collected (27 typhoid-paratyphoid). Salmonellosis cases increased by almost 2-fold in 2017 compared to 2011. The highest rates were reported in August, with infants being the most vulnerable group (17.9%). The majority of isolates were identified in stool samples (91%). Boys slightly outnumbered girls (~1.05:1). Salmonella Enteritidis was the most prevalent serovar (28.5%), followed by Salmo­nella Typhimurium (12.2%) and Salmonella monophasic Typhimurium (10.4%). Non-typhoid isolates displayed low resistance rates to 3rd generation cephalosporins (1%) and ciprofloxacin (0.3%), while the corresponding resistance of typhoid isolates was 10% and 5% respectively. An increasing trend of Salmonella monophasic Typhimurium was recorded, associated with high rates of multidrug resistance, reaching a percentage of 97.8% in 2017.

Conclusions. Salmonellosis epidemiology in Greek chil­dren is comparable to previously published European data. Antimicrobial resistance rates to 3rd-generation cephalosporins and ciprofloxacin for non-typhoid and typhoid-paratyphoid remain low. Notably, there is an increasing prevalence of Salmonella monophasic Typhimurium isolates, associated with multiple antimicrobial resistance.

Published: May 2021

Grande parte dos dados de pesquisa tratados por biólogos estão em planilhas eletrônicas, que são fáceis de implementar como entidades isoladas, mas são inapropriadas para integração com outras fontes de dados ou para consultas avançadas. Várias iniciativas buscam a interpretação e explicitação de esquemas implícitos em planilhas para subsidiar seu mapeamento para padrões abertos de interoperabilidade. Entretanto, tal processo é dissociado do contexto de criação da planilha. Neste artigo apresentamos uma estratégia para a caracterização de planilhas, centrada no contexto de sua criação, e investigamos como ela pode ser usada para aprimorar a interpretação e explicitação automatizadas de esquemas no domínio de uso da Biologia.

TSeg – A Text Segmenter for Corpus Annotation
Authors: Rodrigues Felipe , Semolini Richard , Roman Norton Trevisan , Monteiro Ana Maria
Published: May 2021

This paper describes TSeg – a Java application that allows for both manual and automatic segmentation of a source text into basic units of annotation. TSeg provides a straightforward way to approach this task through a clear point-and-click interface. Once finished the text segmentation, the application outputs an XML file that may be used as input to a more problem specific annotation software. Hence, TSeg moves the identification of basic units of annotation out of the task of annotating these units, making it possible for both problems to be analysed in isolation, thereby reducing the cognitive load on the user and preventing potential damages to the overall outcome of the annotation process.
