Abstract

BACKGROUND. The relationship between the maxillary sinus floor and the roots of the teeth in the upper arch is essential, especially in the correct diagnosis and treatment of odontogenic maxillary sinusitis. The aim of this study was to determine exactly this distance and to observe the most common teeth situated closely to the maxillary sinus.

MATERIAL AND METHODS. The study was performed in 2020, in the ENT Department of “Sfanta Maria” Hospital, and was made based on computed tomography (CT) scans of the sinuses from the clinic’s archive. The image analysis was performed with a radiologic software. For each tooth, from both right and left upper hemiarcade, the distance between the dental root and the bony floor of the maxillary sinus was measured and the average distances were compared.

RESULTS. Among the present teeth analysed, those with the closest distance were the 1st M (95.15% on the right side and 96.23% on the left side), then the second molars (96.08% on the right side and 90% on the left side). The 2nd and 3rd PM had a similar percentage of the sinusal approach, which varied between 82% and 86%.

CONCLUSION. Knowing these dento-sinusal relationships, there is a win-win situation for both the ENT doctor and the dentist. The paraclinical examination necessary for the analysis of the dento-alveolo-sinusal relation and of the afferent pathology is the imaging one, of choice being the CT and CBCT scans.

Abstract
At the present time, a great attention is paid to the ecological innovation, which represents innovation characterization to any ecological change with a positive impact on consumers. Such innovations increase the comfort for consumers and concurrently they represent more effective, more economic, ecological, healthier and safer solutions. Ecological innovation represents any innovation aimed at significant and visible progress towards the goal of sustainable development. This is done by reducing the impact on the environment or achieving a more efficient and responsible use of natural resources, including energy and Zero waste. The aim this paper is evaluation to the perception of Zero waste in the context of ecological innovations in Slovakia. The research is carried out using the Kano model. The results point to the importance of addressing the issue of ZeroWaste, encouraging friends to buy in non-packaging stores and creating a stimulation of advertising to buy products in a non-packaging store. Other attributes of the given issue are perceived by Slovak respondents in the opposite way or have no influence on them. Therefore, it is important to provide sufficient information on this issue and to educate the population in order to increase their interest in this issue and to start behaving responsibly towards waste management.

Abstract
Vehicular queue length measurement is an important parameter to detect the traffic congestion, which is resulted from several issues such as traffic lights, accidents, and poor roads infrastructures. In this paper, a system in real-time is proposed to detect and measure the vehicular queue length at intersections. The proposed system consists of two main steps: the first step is the detection of queue by using frames differencing method to detect the motion in the target areas. If there is no a motion, then the second step is implemented to detect the vehicles in these areas by using Single Shot Multibox Detector (SSD) algorithm. If there are vehicles, that means the queue exists and the measurement process begins. Some modifications are applied on SSD algorithm to fit with in our system and to improve the accuracy of the vehicle detection process. The system is applied on videos obtained by stationary cameras. The experiments demonstrate that this system is able to accurately detect and measure the vehicular queue length.

Published: March 2021

Transient absorption measurements were conducted on pristine and on monoexciton saturatedCsPbBr3 nanocrystals varying in size within the regime of strong quantum confinement. Oncethe difference spectra were translated to absolute transient changes in absorption cross section,a single exciton is shown to completely bleach the band edge absorption peak, and induce anew absorption roughly two times weaker ~100 meV to the blue. Difference spectra obtainedduring Auger recombination of biexcitons demonstrate that addition of a second exciton, ratherthan double the effect of a first, bleaches the blue induced absorption band without producingnet stimulated emission at the band edge. Accompanied by high time resolution transientabsorption spectra pumping at the lowest exciton band, these results identify the blue inducedabsorption as the second transition to 1Se1Sh which is shifted in energy due to unusually strongand promptly rising biexciton repulsion.

The green biological route has been employed to convert macro-sized zinc and copper metal complexes into nano-sized metal complexes. These bioactive metal complexes were synthesized by template condensation process in the chemistry laboratory. The newly synthesized biologically active complexes were converted into nano range from phytochemical aqueous extract of Macrotyloma uniflorum (horse gram). Biologically converted nano complexes have been characterized by physicochemical as well as spectroscopic techniques such as UV-visible spectrophotometer and FTIR. The reduced Cu and Zn metal nanoparticles were analyzed with SEM for shape and size, which showed most of the nanoparticles, were nearly spherical with nano range size. To estimate the potentiality of newly manufactured copper and zinc nanoparticles in vitro and in in vivo studies, i.e. antifungal and antibacterial and anti-cancer activities were performed. The biogenic nanoparticles of Cu and Zn were evaluated for their activity on cancer A-549 cell lines by standard MTT assay for metabolically active mitochondria and cell viability. Further flow cytometric studies showed Cu, and Zn nano complexes had inhibition efficacy of cancer cells compared to normal cells. This study elevates that biosynthesized Cu & Zn nano complexes can be an alternative for the treatment of cancer.

Authors: Castro Franco Bibiana Edivey , Carmona Parra Jaime Alberto 
Published: March 2021

Artículo de Revisión sobre las masculinidades, desde los abordajes conceptuales e investigativos inscritos en la perspectiva de género y desarrollados en latinoamericana. El texto muestra que en América Latina se ha ido constituyendo un bagaje conceptual propio, en torno a caracterizaciones diversas de las masculinidades y las posibilidades de profundización de los estudios de los hombres y las masculinidades, están correlacionados con la complejidad del concepto, continuamente en proceso de transformación, donde diversas disciplinas de las ciencias humanas y sociales convergen, desestabilizando las categorías de hombre y masculinidades, como hechos naturales, normatizados universalmente y anquilosados desde la ética. Se identifican rutas para orientar y llevar a cabo acciones a favor de la equidad de género. Reconociéndose, que estas acciones pueden apoyar a contribuir al desarrollo del estudio y gestión de las masculinidades, especialmente en las universidades en pro de relaciones justas e igualitarias.

Published: March 2021

Introducción. El avance de la cirugía torácica abierta a cirugía torácica asistida por vídeo por tres puertos, y sus posteriores efectos en la recuperación de los pacientes, conllevó al desarrollo de la técnica por un solo puerto, que ha mostrado beneficios en el postoperatorio. El objetivo de este estudio fue comparar los resultados postquirúrgicos de los pacientes sometidos a pleurectomía parietal y decorticación pulmonar toracoscópica asistida por video monopuerto y los obtenidos por toracotomía convencional, en una clínica de cuarto nivel, entre 2016 y 2019.
Métodos. Estudio descriptivo, en el que se incluyeron 79 pacientes llevados a pleurectomía parietal y decorticación pulmonar por toracoscopia asistida por vídeo monopuerto y 25 pacientes operados por toracotomía convencional. Se evaluaron variables sociodemográficas, clínicas y postoperatorias. Se utilizaron las pruebas de Chi2 o de Fisher y las pruebas t de Student y Mann Whitney.
Resultados. La mediana de edad fue menor en el grupo de pacientes operados por toracotomía convencional (28 años, RIC: 26–48, p=0,0005). No hubo diferencia en los tiempos quirúrgicos. Se encontró menor intensidad del dolor y disminución en los días con tubo de tórax, uso de antibióticos, días de UCI y días de estancia hospitalaria en el grupo de pacientes operados por toracoscopia asistida por vídeo monopuerto (p<0,05). ><0,05).
Discusión. Este estudio refuerza la tendencia de mejores resultados postquirúrgicos, menos días de uso del tubo de tórax, uso de antibióticos, necesidad de UCI y días de estancia hospitalaria general con la técnica asistida por vídeo monopuerto comparado con la toracotomía abierta convencional.
Obstetrics Outcomes: A Comparison between Birthing Center and Conventional Labor Ward
Authors: Kafle Deepak Raj 
Published: March 2021

Introduction: Birthing Centers (BC) are increasingly accepted worldwide as an alternate low cost place of birth. The concept is especially relevant for developing countries with limited resources and constraints regarding availability of specialists and hospital beds. The various studies have concluded that when proper risk analyses are conducted and referral rules followed, there is no evidence of increased maternal or perinatal risk at BC compared to standard hospital deliveries.
Materials and Methods: This was a prospective, observational and comparative hospital based study done at Paropakar Maternity and Women’s Hospital (PMWH),Kathmandu. The study was conducted on pregnant women without any known risk factors for complications who were admitted in BC and labor ward (LW) for delivery. Details on mode of delivery, genital tract status, Postpartum hemorrhage (PPH) and neonatal outcomes were collected. Descriptive data analysis was done using SPSS.
Results: Out of 5132 deliveries, 25.3% had no known risk factor and hence were eligible for study; no statistically significant difference was observed between BC & LW in relation to mode of delivery, perineal trauma, PPH and neonatal outcomes; however, practice of episiotomy was significantly less frequent in BC.
Conclusion: When proper risk analyses are conducted and referral rules followed, there is no evidence of adverse obstetrics outcome at BC as compared to standard hospital deliveries. Triaging of low risk pregnancy to a BC is a viable strategy, especially in a resource poor country. This lessens the burden in standard maternity unit so that specialists will be able to provide a quality care to high risk pregnancies.

Published: March 2021

Introduction: Endodontics is specialty field, but the majority of endodontic treatment in Pokhara is provided by the general dental practitioners. The aim of this study was to assess the practice of endodontic treatment protocols among general dental practitioners in Pokhara, Nepal.
Materials and Methods: A cross sectional questionnaire based study was conducted among all the general dental practitioners working in various government, private hospital and clinic of Pokhara. Information about the materials and techniques used in endodontic treatment was collected and descriptive statistical analysis was done.
Results: Out of 89 respondents, only 82 completely filled the questionnaires which were included in the study. Most general dental practitioners (96.34%) regularly treat single rooted endodontic cases. Only 10.97% occasionally use rubber dam during endodontic treatment. Most general dental practitioners (96.34%) used radiographic technique for working length determination. Ninety two percent used stainless steel hand files and step back was the choice of technique by 90.24%. Sodium hypochlorite irrigation and calcium hydroxide intra canal medicaments were used by 93.9% and 98.78% of general dental practitioners respectively. 75.6% used zinc oxide eugenol as root canal sealer and 95.12% obturated root canals with lateral compaction technique. The common complication encountered was mid treatment pain. They seem to overuse antibiotics in cases requiring endodontic therapy. Only 52.43% used autoclave for sterilization of endodontic files. About 92.68% felt the need of further endodontic training and 74.39% preferred post graduate program.
Conclusion: This study indicates that many general dental practitioners of Pokhara are not following well acknowledged endodontic quality guidelines; hence there is a need for further endodontic training.

Authors: Lisnyy I I , Klimchuk L V 
Published: March 2021

Objective: to evaluate the intensity of early postoperative pain after a single preoperative administration of gabapentin during surgical interventions in oncourology.
Materials and methods: patients were randomized into two groups of 25 people each: group 1 (Gr. 1) received gabapentin at a dose of 300 mg for premedication at night, and group 2 (Gr. 2), in which patients did not receive gabapentin. The need for propofol during anesthesia, the need for fentanyl during anesthesia, and the intensity of pain at 2, 4, 6, 12 and 24 hours after surgery were assessed on the VAS scale at rest and during movement.
Results of the study: it was shown that in patients who received gabapentin at a dose of 300 mg for premedication, the need for propofol and fentanyl was significantly lower when compared with patients who did not receive gabapentin, p = 0.0001. The intensity of postoperative pain syndrome in patients in Gr. 1 was significantly lower only when assessed at rest, while no statistically significant differences were found in the quality of pain relief during movement.
Conclusions: the use of gabapentin at a dose of 300 mg for premedication significantly reduces the intensity of postoperative pain at rest, but not during movement, and also reduces the need for propofol and fentanyl during surgery.

Published: March 2021

Background: ultrasound (US)-guided Quadratus Lumborum Block (QLB) is an effective technique in providing analgesia for abdominal surgery. This study was designed to evaluate the efficacy of a US-guided Quadratus Lumborum Block (QLB) compare it with a caudal block in children after acute appendicitis.
Patients and methods. Forty eight (48) ASA 1–2, 1–5-year-old children scheduled for elective acute appendicites were studied. All patients received general anesthesia; sevoflurane was used for induction and maintenance of anesthesia and laryngeal mask airway (LMA) was used to secure the airway. After securing an intravenous cannula, patients were randomized to a US-guided Quadratus Lumborum Block (QLB) (n = 24) (group Q) using 0.5 ml/kg of 0.25 % bupivacaine, injected on the same side of surgery, and group C received a caudal block using 1 ml/kg of 0.2 % bupivacaine (n = 24). Surgery was allowed 15 min after administration of the block. Block failure was considered in case of gross movement or more than 20 % change in heart rate and/or ABP persisting more than 1 min after skin incision. Any adverse events were recorded. After surgery, patients remained for 4 h in the recovery room. Postoperative analgesia was evaluated using Children and Infants Postoperative Pain Scale (CHIPPS). An anesthesiologist, who was not part of the study team, evaluated the need for rescue analgesia in the intraoperative and postoperative period and a recovery nurse collected the data. If the CHIPPS score was greater than 4, a rescue analgesia of 20 mg/kg acetaminophen was administered.
Results. No difference was found in hemodynamics in both groups. Also, intraoperative fentanyl consumption was not different and no rescue analgesia was required in the postanesthesia care unit.
Conclusion. US-guided Quadratus Lumborum Block (QLB) is as effective as caudal block in providing immediate postoperative analgesia in acute appendicitis.
