Authors:   ,   Andrews University, Wensell Egil
Published: June 2023

Problem. The first Seventh-day Adventist educational institution in South America was River Plate College, Entre Rios, Argentina, founded in 1898. After eighty-three years the school has grown considerably and has developed into a full-fledged college. Until now there has been no comprehensive written history of this school. This lack has been a problem for the college in the past. Method. This study utilized the documentary-historical method of research. Important information regarding River Plate College contained in books, periodical articles, school bulletins, board minutes, school reports, correspondence, and other documents pertaining to the history, development, and operation o£ the college are utilized. Conclusions. The conclusions reached in this study are as follows: 1. River Plate College was established in order to solve a deep spiritual need of the early Adventist believers of Argentina. They desired their children to receive a Christian education, to be fully converted, and to become workers in the Seventh-day Adventist church. 2. River Plate College was established by Adventist believers residing in Argentina with donations given by themselves. 3. An important characteristic of River Plate College was the spiritual atmosphere that permeated all the activities of the school. The example given by the teachers' lives was large the means by which students learned to be Christians. Until 1950, 70.43 percent of the college's graduates entered church work. 4. Innovations that River Plate College introduced in the Argentine educational system Include (1) a school curriculum in which education was provided through both manual labor and academic means, and (2) coeducation as a means to promote better development of the social aspect of the students' personalities. 5. A knowledge of the history of River Plate College could well be a source of inspiration for young Christians as they seek to know more of the faith, self-denial, and dedication of Adventist believers connected with the early days of River Plate College.

S ciljem kognitivnoaktivnog uključivanja studenata, u proces poučavanja studentima koji su na početku visokoškolskog obrazovanja pružena je vršnjačka podrška u stjecanju predmetno specifičnog znanja konceptualnom mapom. Istraživanje se provelo akademske 2021./2022. i 2022./2023. godine s ukupno pedeset studenata prijediplomskog sveučilišnog studija Biologija Odjela za biologiju Sveučilišta u Osijeku. Studenti (budući učitelji/nastavnici Prirode, Biologije i Kemije), koji su bili u ulozi onih koji poučavaju, osmisli su i proveli u prvoj fazi istraživanja nastavu u kojoj su se izmjenjivale različite studentske aktivnosti, a koje ujedno podržavaju uočavanje i izdvajanje ključnih pojmova i veza među njima što je neophodno za dostizanje znanja na višim kognitivnim razinama. Istu nastavu su potom programirali te na taj način prilagodili online učenju. U drugoj fazi istraživanja sa studentima se provela inicijalna pisana provjera znanja te su potom upućeni na samostalno online učenje nakon kojeg je uslijedila završna pisana provjera. Usporedbom inicijalne i završne pisane provjere znanja utvrdila se učinkovitost vršnjačke podrške tijekom samostalnog online učenja. Rezultati ukazuju da su studenti postigli bolju riješenost u pitanjima svih testiranih kognitivnih razina u završnoj pisanoj provjeri znanja u odnosu na inicijalnu.
Estrategias para la comprensión lectora: Una revisión de estudios en Latinoamérica
Authors: Armijos Uzho Angie , Paucar Guayara Carmen , Quintero Barberi Jesús
Published: June 2023

La comprensión lectora es uno de los retos más importantes en la educación latinoamericana, debido a que un número considerable de estudiantes presenta dificultades en la lectura, el análisis y la discusión de textos académicos. En la mayoría de casos se ha evidenciado una deficiente aplicación de estrategias metodológicas para que el alumnado logre adecuadamente comprender y sintetizar la información. Actualmente, los jóvenes realizan las lecturas principalmente porque el docente lo solicita como un requisito evaluativo de alguna actividad, pero no como una práctica de interés general que fomenta la comprensión, la deducción y posteriormente la construcción de saberes con un aprendizaje significativo. En tal sentido, la metodología de esta investigación se centró en analizar, a través de un enfoque cualitativo, veinte artículos científicos almacenados en la base de datos de Redalyc por medio de una revisión sistemática en la que se pretenden determinar las estrategias más innovadoras y tecnológicas, como el arborigrama, el parafraseo, las infografías, las historietas, los organizadores gráficos en línea y la música, como elementos atractivos que permitan a los docentes incentivar a los jóvenes para que obtengan un hábito de lectura aprovechando sus dispositivos móviles, y a los estudiantes, lograr una comprensión lectora adecuada.

Locating Undocumented Migrant Populations: A Case Study Using Statistical Data of Cork City of Sanctuary, Ireland
Authors: Budhoo Jessica
Published: June 2023

Perilous countries often produce citizens who will risk becoming undocumented in a foreign country in order to seek safety. However, the term undocumented migrant includes many sub- categories such as trafficked individuals, students who have outstayed their visas or those who unintentionally transitioned from legal migrant to undocumented migrant. Cork City of Sanctuary was created to protect all communities including documented and undocumented migrants living in Cork City Ireland. Government and social service institutions that have been established for migrants are only beneficial if they are spatially accessible to highly-vulnerable migrant populations. This study utilized interview data, a Principal Component Analysis and a K-Means Cluster analysis to create a highly-vulnerable migrant population segmentation of Cork City of Sanctuary. As a result, the study found that creating segmentations of highly-vulnerable migrant populations Cork City was possible however, the available statistical data was limiting considering migrants have many sub-categories in which government census data does not capture, there was a lack in variety within the various census variables, and available open source data does not provide statistical information on undocumented and documented migrants collected from sanctuary colleges/university or sanctuary hospitals within Cork City of Sanctuary. 
A More Intimate Ecology: Reframing the Relationship between the Researcher and the Research(ed)
Authors: Estien Cesar
Published: June 2023

Ecology is vast and varied, not just in academic subfields but in how individuals equip themselves with it. In this work, I am trying to access a more intentional and intimate ecology by inserting queer theory to rupture Western scientific training that has created a structured ecology that often prevents researchers from fully engaging with the ecosphere. In this article, I move beyond scientific understandings of human and nonhuman animal relationships to reimagine ecology as a more intimate field. I argue that complete insertion in, rather than removal from, science creates a stronger approach that facilitates a deeper connection with study organisms and non-human beings. I then use this connection to analyze (1) a core concept in ecology, human-wildlife conflict, as a constructed concept and (2) the urban coyote as a Queer ecological being that may be used to understand the experience of a marginalized and oppressed body in academia. This work rethinks what ecology could be to traditional ecologists by demonstrating how an urban ecologist explores human-non-human connections and interactions through the lens of queer theory.
The Study of Opening and Closing of Conversations in Oral English Textbooks
Authors: Zhou Hanru , Yu Qinglan
Published: June 2023

Language communication ability refers to the ability to use language in society. The acquisition of this ability by second language learners mostly relies on textbook dialogues adapted from real-life conversations. Therefore, whether scripted textbook conversations can help improve second language learners’ language communication ability should be taken seriously by the academic circle. This paper has analyzed all the conversational texts in the book Functioning in an Intercultural Community, using book1 and book2 as corpus and finds that there are deficiencies in the opening and closing of the conversation in the textbook. This study suggests that textbook compilers should improve the completeness, diversity, and colloquialism of the beginning and end of conversations, and teachers appropriately extend the form of the opening and closing of the conversation during the teaching process.

Мета. Метою статті є виявлення й опис лінгвостилістичних маркерів розмовності в художній оповіді Олександра Вільчинського. Методи дослідження. Для реалізації мети використано такі методи та прийоми, як: описовий, семантико-стилістичний, контекстуально-інтерпретаційний, прийом кількісних підрахунків. Результати. Письменник як мовна особистість формувався на території Західної, Центральної та Південної України, що й зумовило певний склад ареалізмів у його словнику, зокрема діалектизмів та розмовно-просторічних слів. Шляхом аналізу мови його повістей «Криївка», «У степу під Авдіївкою», романів «Дерева на дахах» та «Інші двері» виявлено, що стилетвірною ознакою художньої оповіді митця є стилізація розмовності з метою відтворення живого мовлення українців. Висновки. Виразними маркерами розмовності художньої оповіді О. Вільчинського є широке вживання у його прозі таких ареалізмів, як територіальні діалектизми і розмовно-просторічна лексика. У повісті «Криївка», романах «Дерева на дахах», «Інші двері» активно функціонує діалектна лексика галицько-буковинської та волинської груп говорів на позначення осіб, одягу, взуття, побутових речей, властивостей предметів, певних дій та процесів тощо. Ці ареальні компоненти літературної мови відтворюють побут, звичаї та особливості мовлення жителів Західної України. Для стилізації соціолінгвальних умов Сходу України у повісті «У степу під Авдіївкою» письменник уводить у художню оповідь елементи суржику. Розмовно-просторічна лексика здебільшого представляє рідну для митця Тернопільщину та інші області Західної України. Найбільш частотними є іменники та дієслова, що репрезентують такі лексико-семантичні групи: назви осіб, одягу та взуття, продуктів харчування, транспорту, воєнної техніки та боєприпасів (у повісті «У степу під Авдіївкою»), процесів та дій тощо.

Published: June 2023

White spot syndrome virus (WSSV) merupakan salah satu penyakit infeksi virus yang dapat menyebabkan tingginya mortalitas pada budidaya udang vaname. Udang (±19 g) dipelihara dalam 9 kontainer dengan kepadatan masing-masing 10 ekor/kontainer dan diberi pakan 3% dari bobot biomassa setiap hari. Udang dikelompokkan menjadi tiga perlakuan dengan masing-masing 3 ulangan yaitu pakan tanpa suplementasi alginat sebagai kontrol, suplementasi pakan natrium alginat Sargassum sp. dengan dosis 1 g/kg pakan + vitamin C 0,2 g/kg pakan, dan suplementasi pakan natrium alginat Sargassum sp. dengan dosis 2 g/kg pakan. Setelah 14 hari diberi perlakuan, udang diinjeksikan filtrat white spot syndrome virus dan phosphate buffer saline (PBS) dengan perbandingan 1:1 untuk uji tantang. Parameter yang diamati meliputi kelangsungan hidup, relative percent survival (RPS), mean time to death (MTD), tingkah laku dan gejala klinis udang, histologi hepatopankreas, identifikasi white spot syndrome virus dengan PCR, dan kualitas air. Hasil penelitian menunjukkan bahwa suplementasi natrium alginat Sargassum sp. melindungi udang terhadap white spot syndrome virus 14,80 jam lebih lama dalam kelangsungan hidup dibandingkan dengan kelompok kontrol. Namun suplementasi natrium alginat Sargassum sp. dari perairan Lampung belum mampu melindungi udang terhadap white spot syndrome virus setelah 72 jam terinfeksi.

Matras Beach is one of the beach in the Bangka Belitung Archipelago used as a tourist destination. The coastline is the line that separates land and sea which can change every year. The aims of this study are to determine the change and rate of shoreline change before (2000-2010) and after the breakwater (2010-2020), and its impact on beach tourism at Matras Beach. The method used in this research is the digitization method and the Digital Shoreline Analysis System. The results showed that from 2000 to 2010, before the Matras Beach breakwater, there was a maximum increase of 34.23 m at a rate of 3.42 m/year and a maximum reduction of -35.10 m at a rate of -3.51 m/year, while after the breakwater in 2010-2020 Matras Beach experienced a maximum increase of 72.79 m at a rate of 7.28 m/year and a maximum reduction of -81.72 m at a rate of -8.17 m/year. This change resulted in 3.64 ha of abrasion and 1.50 ha of accretion before the breakwater and 8.48 ha of abrasion and 4.20 ha of accretion after the breakwater. This abrasion has a negative impact on beach tourism on Matras Beach because it will damage vegetation and buildings on the coast.

Published: June 2023

Oilfield-produced water treatment using raw Kapok fiber (RKF) and a modified surface of Kapok fiber followed by an ultrafiltration membrane was conducted to reduce total dissolved solids (TDS), phenol, and barium. Variables considered in the experiment were contact times (30, 60, 90 min.), the flow rate of samples (5, 6, and 7 L/min), and trans-membrane pressure of ultrafiltration membrane (0.25, 0.35, and 0.50 bar). Raw Kapok fiber and modified surface Kapok fiber were used to investigate the effect of Kapok fiber on total dissolved solids, phenol, and barium removals from produced water. The results showed that raw KF decreased the TDS, phenol, and barium by 51.81%, 62.63%, and 54.20%, respectively. Treatment of raw Kapok fiber column filtrate using ultrafiltration membranes (UF) showed the removal of TDS, barium, and phenol achieved 73.15%, 42.44%, and 79.45%, respectively, at a flow rate of 5 L/min, TMP of 0.25 bar, and contact time of 90 min. Modifying the Kapok fiber surface using sodium hydroxide solution (5 wt%) and hot water (98.5 °C) reduced the TDS, phenol, and barium to 57.32%, 65.83%, and 79.08%, respectively. Further, at the same operating condition, the modified surface of Kapok fiber followed by UF decreased 94.31% TDS, 84.20% phenol, and 56.23% barium, respectively. The results show that modification of the Kapok fiber surface followed by UF can be used to remove the TDS, phenol, and barium from produced water.

Authors: Hannarong Juthamas , Tocharoenchok Teerapong
Published: June 2023

Objective: Our aim was to report on the long-term outcomes of patients who underwent RV-PA conduit placement at our institute.
Materials and Methods: We retrospectively reviewed 407 RV-PA conduit placements from January 1997 to December 2018. The primary outcomes were freedom from and risk factor(s) for conduit re-operation. The secondary outcomes were survival, freedom from conduit dysfunction and conduit-related catheter intervention.
Results: Of all the included patients, 209 were male (51.4%) and the median age at the operation was nine years (IQR 6, 18 years). The most commonly used conduit types were bovine jugular vein conduit (125, 30.7%), pulmonary homograft (122, 30.0%), and aortic homograft (76, 18.7%). The median follow-up time was 5.1 years (IQR 0.9, 9.2 years). The overall survival was 92.2% at 5 years. Freedom from re-operation was 95.4% and 84.2%,  at 5 and 10 years. Factors related to conduit reoperation were age at operation less than 1 year, diagnosis rather than pulmonary atresia or stenosis, conduit size less than 18 mm, and conduit z-score greater than 3 (all p<0.01). In multivariate analysis, a significant contributing factor for re-operation was small conduit size (13 mm or smaller; HR 6.87 (95%CI 2.36, 20.01); p<0.001, 14–17 mm; HR 3.20 (95%CI 1.28, 8.00); p=0.013). Freedom from conduit dysfunction was 84.4% and 61.6% at 5 and 10 years. Freedom from conduit intervention was 94.4% and 89.3% at 5 and 10 years.
Conclusion: Our study showed that patients had excellent survival with acceptable freedom from re-operation despite deteriorated conduit function. Small conduit size is associated with re-operation.

Authors: Ruangtrakool Ravit , Krajangjit Piyaporn
Published: June 2023

Objective: The purpose of this study was to examine factors affecting early complications following transanal endorectal pull-through (TERPT) in  patients with Hirschprung’s disease.
Materials and Methods: Retrospective chart reviews of  patients with Hirschsprung’s disease who underwent TERPT/ abdominal assisted TERPT at Siriraj Hospital between January 2009 and  December 2019 was carried out. .
Results: The overall complication rate was 26% (43/163). The complications were as follows:  14 cases of anastomotic strictures (32.6%), five cases of abscess at anastomosis (11.6%), and three cases of anastomotic leakages (7.0%). In regards to preoperative bowel preparation,  when comparing  those with and those without post-operative complications, the amount of NSS for rectal irrigation (ml/Kg), duration required (days), and duration of changed diet (days) were the same. Colostomy prior to a  pull-through operation could not prevent post-operative complications following endorectal pull-through (p = 1.000). The incidences of early complications following TERPT and  abdominal assisted TERPT was  the same (p = 0.344). Abdominal assisted TERPT had a higher incidence (4%) of anastomotic leakages whereas TERPT had a higher rate of anastomosis strictures (12%) compared to o abdominal assisted TERPT (5%). The higher the transitional zone, the higher the complication rate. Anastomotic leakages, the most serious complication, rarely occurred following TERPT in the  low transitional zone.
Conclusion: There was no significant risk factor associated with early surgical complications following TERPT. Abdominal assisted TERPT should be selected properly according to the  level of transitional zone. The complications correlate with whether a perfect pull-through operation could be performed or not.
Unresolved laboratory issues of the heterozygous state of β-thalassemia: a literature review
Authors: Thilakarathne Shyamali , Jayaweera Udayanga P , Premawardhena Anuja
Published: June 2023

Although considered a mild clinical condition, many laboratory issues of the carrier state of beta-thalassaemia remain unresolved. Accurate laboratory screening of beta-thalassaemia traits is crucial for preventing the birth of a beta-thalassaemia major child. Identification of carriers in the laboratory is affected by factors that influence red cell indices and HbA2 quantification. Silent mutations and co-inheriting genetic and non-genetic factors affect red cell indices which decreases the effectiveness of the conventional approach. Similarly, the type of beta mutation, co-inheriting genetic and non-genetic factors, and technical aspects, including the analytical method used and variations in the HbA2 cutoff values, affect the HbA2 results leading to further confusion. However, the combination of MCV, MCH and haemoglobin analysis increases the diagnostic accuracy. Diagnostic problems arising from non-genetic factors can be eliminated by carefully screening the patient’s clinical history. Still, issues due to certain genetic factors, such as Krüppel-like factor 1 gene mutations and alpha triplication remain unresolved. Each laboratory should determine the populationspecific reference ranges and be wary of machine-related variations of HbA2 levels, the prevalence of silent mutations in the community.

Immunosuppressive treatment (IST) and hematopoietic cell transplant (HCT) are standard therapies for severe aplastic anemia (SAA). We report on conditional survival and standardized mortality ratios (SMR), which compare the mortality risk with the general population adjusted for age, gender, and race/ethnicity, in patients with SAA alive for at least 12 months after treatment with IST or HCT between 2000 and 2018. Given changes to treatment regimens and differences in length of follow-up, two treatment periods were defined a priori: 2000-2010 and 2011-2018. The SMR of patients treated during the period 2000-2010 and who survived one year were 3.50 (95% confidence interval [CI]: 2.62-4.58), 4.12 (95% CI: 3.20-5.21), and 8.62 (95% CI: 6.88-10.67) after IST, matched related donor HCT, and alternative donor HCT, respectively. For the period 2011-2018, the corresponding SMR were 2.89 (95% CI: 1.54-4.94), 3.12 (95% CI: 1.90-4.82), and 4.75 (95% CI: 3.45-6.38), respectively. For IST patients, their mortality risk decreased over time, and became comparable to the general population by five years. For patients who underwent HCT during 2000-2010 and 2011-2018, their mortality risk became comparable to the general population after ten years and after five years, respectively. Thus, 1-year survivors after IST or HCT can expect their longevity beyond five years to be comparable to that of the general US population.

Published: June 2023

Background: The most important global cause of mortality is suicide.Global suicide rates have increased 60% in the last 45 years. Unnatural death is one of the indications of social and mental health in a society.It is often neglected by researcher, health professionals, health policy makers and the medical profession.Unnatural death by suicide relates to multiple factors eg. low socio-economic condition, dowry system, lack of education, failure of love, poverty etc. Shooting, hanging and stabbing are a hard way of committing suicide and typically a male choice.Poisoning and drowning are soft way of committing suicide and typically a female choice. This article was aimed to find out the pattern and demography of suicidal death.

Materials and method: To find out the pattern of suicidal death, a retrospective data was collected from the records of Forensic Medicine Department in Sir Salimullah Medical College, Dhaka for the period of 1 year from January 2021 to December 2021.

Objective: The objective of this study was to find out pattern and demography of suicidal death, its distribution according to age, sex, common method used by victims and in this way try to identify the causative factors and develop the preventive measures that are essential to reduce suicidal death.

Results: The commonest methods of committing suicide were found hanging which was 60.3%, followed by poisoning 26%, burn 1.34%. Most of the victims (25%) were from the age group 1-15 years. Out of 328 cases 170 (52%) were male and 158 (48%) were female. Among them 196 (59.8%) were married and 132 (40.2%) were unmarried. Most common poison was Organo Phosphorus Compound (OPC).

Conclusion: To reduce the number of suicide a well designed and comprehensive program is needed which will identify the causative factors and which might help in prevention of suicide.

Published: June 2023

Background: Oral pyogenic granuloma is a soft-tissue lesion of the oral mucosa. This lesion has a tendency to recur after surgical excision.

Materials and Methods: A total of 35 patients underwent surgical excision of pyogenic granuloma in the period from January 2019 to June 2022. Two surgical techniques were used to remove pyogenic granuloma: simple excision with root planing and modified excision with deep curettage.

Results: Females (54%) were slightly more predominant than males (46%). The upper and lower jaws were almost equally affected by the lesion with more predilection toward the posterior region. The size of the lesion ranged from 0.5 to 3 cm in diameter with slow-growing rate. Rural residents were more affected (57%) than urban people. The lesion appears clinically as a small red mass with sessile base, and these clinical features were similar in pregnant and nonpregnant women. The recurrence rate was 14.8% and seen only in patients treated by simple excision. Histopathological feature was consistent with inflammatory hyperplastic lesion, and there was no radiographic evidence of bone resorption associated with the lesion.

Conclusion: Modified excision with deep curettage prevents the recurrence of the lesion after 1-year follow-up.

Authors: Chowdhury Sabrina Farida , Bilquise Regina , Rahman Ashiqur , Tasmia Gul E Noor , Rabby Md Atiqul Islam , Hossen Mahbuba
Published: June 2023

COVID-19 pandemic has brought about many challenges in dental practice for dental professionals and their team. The route of transmission of the virus and the nature of dental service has put dental professionals at risk of being exposed and infected by the virus and at the same time making dentistry itself a part of the infectious chain of COVID-19. The World Health Organization (WHO) has advised dental professionals across the world to limit dental practice to emergency cases only and postpone all non-essential dental services. According to Bangladesh Dental Society, about 10,000 practicing dentists and near about 20,000 supporting staff are involved in dental health practice in the country. There are about 4,000 dental clinics only in Dhaka city. A dental practice guideline has been developed by Bangladesh Dental Society to employ by dental professionals during COVID-19 pandemic. However, we feel that efforts to explore the real scenario of proper safety precaution and maintenance of public health measures in COVID-19 is less evident in the manuals in the context of public health and patient safety in Bangladesh. Hence, we proposed this review paper through an extensive literature and guidelines search to explore the risks of COVID-19 transmission inside dental settings, explore recommended safety protocols to minimize those risks and address the challenges associated with resuming regular dental and oral health practice.

Authors: Islam Md Shoriful , Haq KM Reza Ul , Siddiqui Asif Imran , Tabassum Refat , Lodi Russel Ahmed Khan
Published: June 2023

Background: Baker's cyst is usually degenerative in origin, infective etiology is rare and tubercular origin is exceptional. Tuberculosis (TB) of the musculoskeletal system is an uncommon infection caused by tuberculous bacilli and constitutes 1% - 5% of all forms of TB. About 30% of skeletal TB involves the joints, the knee being the 3rd most commonly affected after the spine and the hip. Knee tuberculosis commonly presents as synovitis or arthritis. We are presenting a case of a young female with clinico-radiological features suggestive of Baker's cyst. Complete excision of Baker's cyst and histopathology was done. Histopathological examination revealed multiple epitheloid granulomas pointing toward a tubercular etiology. Standard ATT protocol with rehabilitation was followed. The patient was asymptomatic at 1st year with complete resolution of symptoms and full range of motion. This case highlights the need to maintain high index of suspicion in cases hailing from endemic region with unusual intra-operative findings; also, the importance of routine histopathological examination.

Controlled Hypotension for Functional Endoscopic Sinus Surgery: A Comparative study between Dexmedetomidine versus Esmolol
Authors: Shaheen Md Shafiul Alam , Sardar Kawsar , Chowdhury AKM Nurnobi , Mondal Subrata Kumar , Ahmed Raju , Alam SM Shafiqul
Published: June 2023

Background: Functional endoscopic sinus surgery (FESS) requires effective control of bleeding forbetter visibility of the operating field and reduced risk of injury to the optic nerve or the internal carotidartery. Controlled hypotension is a technique used to limit intraoperative blood loss to provide the bestpossible field for surgery.
Objectives: Our study is undertaken to evaluate the efficacy of dexmedetomidine as a hypotensive agentin comparison to esmolol in Functional Endoscopic Sinus Surgery (FESS).
Method: Sixty (60) patients 20 – 50 years of age, ASA I/II scheduled for FESS were equally randomlyassigned to two equal groups of 30 patients each. Patients of group D received dexmedetomidine 1μg/kgover 10 min before induction of anesthesia followed by 0.4 – 0.8 μg/kg/hr infusion during maintenanceand group E received esmolol loading dose 1mg/kg was infused over one min followed by 0.4 – 0.8 mg/kg/hr infusion during maintenance to maintain mean arterial blood pressure (MAP) between (55 – 65mmHg). The surgical field was assessed using Average Category Scale and average blood loss wascalculated. Hemodynamic variables (MAP, HR); intraoperative fentanyl consumption and total recoveryfrom anesthesia (Aldrete’s score e”9) were recorded. Sedation score was determined at 10, 20, 30, 40 & 60min after tracheal extubation and time to first analgesic demand was also recorded.
Results: In both group D and group E reached the desired MAP (55 – 65 mmHg) with no intergroupdifference in MAP or HR. Mean intraoperative fentanyl consumption was significantly lower in group Dthan group E. Recovery time to achieved Aldrete’s score e”9 were significantly lower in group E comparedwith group D. The sedation score were significantly lower in group E compared with group D at 10minutes, 20 minutes and 30 minutes postoperatively. Time to first analgesic demand was significantlylonger in group D.
Conclusion: The result of this study showed that both dexmedetomidine and esmolol can be used asagents for controlled hypotension and are effective in providing ideal surgical field during FESS. Butdexmedetomidine offers the advantage of inherent analgesic, sedative and anesthetic sparing effect.

Authors: Kalam Farzana , Hussain Pervez Altaf , Ahmed Masud , Masum Abdullah
Published: June 2023

Introduction: Traditionally Procedural Sedation and Analgesia (PSA) is provided by various drugsand its combinations with mixed effect regarding safety and efficacy.
Objective: The aim of the study was to compare the combination of Ketamine & Propofol (Ketofol) andKetamine-Diazepam for PSA in day case surgery.
Materials & Methods: This prospective study was carried out in CMH Dhaka on sixty patients equallydivided in two groups between the period of May 2015 to September 2015. Group I patients receivedInjection Ketamine 1mg/kg & Injection Propofol 1mg/kg combination while group II patients receivedInjection Ketamine 2mg/kg & Injection Diazepam 0.2mg/kg combination. Clinical parameters like pulserate, non invasive blood pressure (NIBP), percentage saturation of oxygen (SpO2) were monitored, recordedand analyzed. Recovery was assessed by Aldred Recovery Score (ARS) and compared between groups.
Results: Rise of heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP) were statisticallysignificant in group II patients when compared to group I both during the procedure & recovery but riseof mean arterial pressure (MAP) was significant only during procedure. The recovery time in group IIpatients (24.7 ± 3.6 min) was significantly higher (29.7 ± 4.1 min) than group I patients. Side effects likeexcessive bronchial secretion and postoperative agitation were also significantly lesser in Ketofol group.
Conclusion: Ketofol provides safer and more effective sedation and analgesia than Ketamine andDiazepam combination.

Efficacy of Magnesium Sulphate to Prevent Arterial Pressure Increases During Laparoscopic Cholecystectomy
Authors: Hoq Naimul , Maruf Abdullah Al
Published: June 2023

Background: Carbon dioxide pneumoperitoneum (PP) for laparoscopic surgery increases arterialpressure and systemic vascular resistance, these vasopressor responses are likely to be due to increasedrelease of catecholamine. Magnesium is well known to inhibit catecholamine release and attenuatevasopressin stimulated vasoconstriction.
Objectives: This study has been undertaken with a view to find out the efficacy of magnesium sulphateto prevent arterial pressure increases associated with carbon dioxide pneumoperitoneum (PP) in patientsundergoing laparoscopic cholecystectomy.
Methods: Sixty patients, of either sex, 18 60 years of age, undergoing elective laparoscopic cholecystectomywere randomly allocated in one of the two group’s containing 30 patients each. Magnesium SulphateGroup “M” received magnesium sulphate 30 mg/kg intravenously as a bolus beforecarbon dioxidepneumoperitoneum (PP).A control Group “C” received same volume of normal salinebefore carbon dioxidepneumoperitoneum (PP).
Results: Mean arterial pressure was significantly less throughout the period ofpneumoperitoneum inpatients of Group M. Intravenous labetalol was required in 46.66% (14out of 30) of the patients in groupC to control intraoperative hypertension and it was clinicallysignificant in comparison to group M.
Conclusion: Our study concluded that intravenous Magnesium Sulphate administered before carbondioxide pneumoperitoneum (PP) attenuates arterial pressure increases during laparoscopiccholecystectomy effectively and provides better hemodynamic stability.
