Authors: Widodo Widodo
Published: April 2022

Kemajuan teknologi informasi dan komunikasi sudah semakin canggih dan cepat, sehingga mempengaruhi setiap aspek kehidupan manusia, tanpa disadari produk teknologi sudah menjadi kebutuhan sehari-hari, penggunaan televisi, telepon, fax, handphone, dan internet sudah bukan hal yang aneh dan baru khususnya di kota-kota besar. Permasalahan dalam penelitian ini ialah bagaimana penegakan hukum terhadap kejahatan penipuan melalui SMS dengan menerapkan Pasal 378 KUHP belum maksimal sesuai Putusan Nomor 639/Pid.B/2013/PN.Jkt.Sel) dan peran penyidik Polri dalam membuktikan kasus kejahatan penipuan melalui SMS dengan menerapkan Pasal 28 ayat (1) jo. Pasal 45 ayat (2) UU No. 11 Tahun 2008 tentang ITE. Penelitian ini bersifat deskriptif karena menggambarkan peraturan perundang-undangan yang berlaku dan dikaitkan dengan teori-teori hukum dalam praktik pelaksanaannya yang berkaitan dengan permasalahan akan diteliti. Hasilnya penindakan kasus penipuan dengan menggunakan media elektronik belum maksimal karena masih banyaknya aparat penegak hukum baik penyidik kepolisian, jaksa penuntut umum dan hakim pada tingkat persidangan yang hanya menerapkan persangkaan penipuan sebagaimana dimaksud dalam Pasal 378 KUHP, yang belum maksimal dan belum memenuhi rasa keadilan, sehingga seharusnya terhadap pelaku penipuan menggunakan SMS atau media elektronik dapat dijerat dengan menggunakan Pasal 28 ayat (1) jo. Pasal 45 UU No. 11 Tahun 2008 tentang ITE, sehingga pemidanaannya lebih maksimal dan memungkinkan kepada korbannya untuk mendapatkan ganti kerugian karena dalam pasal tersebut terdapat ancaman dengan denda hingga satu miliar rupiah.

FORECASTING SPATIALLY CORRELATED TARGETS: SIMULTANEOUS PREDICTION OF HOUSING MARKET ACTIVITY ACROSS MULTIPLE AREAS
Authors: Lee Changro
Published: April 2022

This study involved the development of an approach to forecast house prices and trading volumes across multiple areas simultaneously. Spatially correlated targets, such as house prices, can be predicted more accurately by leveraging the correlations across adjacent areas. A multi-output recurrent neural network, a deep learning algorithm specifically developed to analyze sequence data, was utilized to forecast the house prices and trading volumes in the four chosen study areas. The forecasting accuracy of future house prices in one of the four geographical areas clearly improved; this area was found to be a price-lagging area, and the forecasting accuracy of this area significantly increased by exploiting the information of a price-leading area. As for the prediction of trading volumes, the difference in performance between the multi-output recurrent neural network and conventional models was very small. The results of this study are expected to promote the use of deep learning to predict the housing market activity through a simultaneous forecasting framework.

We present multiband observations of an extremely dusty star-forming lensed galaxy (HERS1) at z = 2.553. High-resolution maps of HST/WFC3, SMA, and ALMA show a partial Einstein ring with a radius of ∼3″. The deeper HST observations also show the presence of a lensing arc feature associated with a second lens source, identified to be at the same redshift as the bright arc based on a detection of the [N ii] 205 μm emission line with ALMA. A detailed model of the lensing system is constructed using the high-resolution HST/WFC3 image, which allows us to study the source-plane properties and connect rest-frame optical emission with properties of the galaxy as seen in submillimeter and millimeter wavelengths. Corrected for lensing magnification, the spectral energy distribution fitting results yield an intrinsic star formation rate of about 1000 ± 260 M

A Rich Satellite Population of the NGC 4437 Group and Implications of a Magnitude Gap for Galaxy Group Assembly History
Authors: Kim Yoo Jung , Kang Jisu , Lee Myung Gyoon , Jang In Sung
Published: April 2022

Both observations and cosmological simulations have recently shown that there is a large scatter in the number of satellites of Milky Way (MW)–like galaxies. In this study, we investigate the relation between the satellite number and galaxy group assembly history using the r-band magnitude gap (Δm
12) between the brightest and second-brightest galaxies as an indicator. From 20 deg2 of the Hyper Suprime-Cam Subaru Strategic Program Wide layer, we identify 17 dwarf satellite candidates around NGC 4437, a spiral galaxy with about one-fourth of the MW stellar mass. We estimate their distances using the surface brightness fluctuation method. Then we confirm five candidates as members of the NGC 4437 group, resulting in a total of seven group members. Combining the NGC 4437 group (with Δm
12 = 2.5 mag) with other groups in the literature, we find a stratification of the satellite number by Δm
12 for a given host stellar mass. The satellite number for the given host stellar mass decreases as Δm
12 increases. The same trend is found in simulated galaxy groups in the TNG50 simulation of the IllustrisTNG project. We also find that the host galaxies in groups with a smaller Δm
12 (like NGC 4437) have assembled their halo mass more recently than those in larger gap groups, and that their stellar-to-halo mass ratios increase as Δm
12 increases. These results show that the large scatter in the satellite number is consistent with a large range of Δm
12, indicating diverse group assembly histories.
Fluorine Abundances in the Galactic Nuclear Star Cluster
Authors: Guerço Rafael , Ramírez Solange , Cunha Katia , Smith Verne V. , Prantzos Nikos , Sellgren Kris , Daflon Simone
Published: April 2022

Abundances of fluorine (19F), as well as isotopic ratios of 16O/17O, are derived in a sample of luminous young (∼107–108 yr) red giants in the Galactic center (with galactocentric distances ranging from 0.6–30 pc), using high-resolution infrared spectra and vibration-rotation lines of H19F near λ2.3 μm. Five of the six red giants are members of the Nuclear star cluster that orbits the central supermassive black hole. Previous investigations of the chemical evolution of 19F in Galactic thin and thick-disk stars have revealed that the nucleosynthetic origins of 19F may be rather complex, resulting from two, or more, astrophysical sites; fluorine abundances behave as a primary element with respect to Fe abundances for thick-disk stars and as a secondary element in thin-disk stars. The Galactic center red giants analyzed fall within the thin-disk relation of F with Fe, having near-solar, to slightly larger, abundances of Fe (〈[Fe/H]〉 = +0.08 ± 0.04), with a slight enhancement of the F/Fe abundance ratio (〈[F/Fe]〉 = +0.28 ± 0.17). In terms of their F and Fe abundances, the Galactic center stars follow the thin-disk population, which requires an efficient source of 19F that could be the winds from core-He burning Wolf–Rayet stars, or thermally pulsing AGB stars, or a combination of both. The observed increase of [F/Fe] with increasing [Fe/H] found in thin-disk and Galactic center stars is not predicted by any published chemical evolution models that are discussed, thus a quantitative understanding of yields from the various possible sources of 19F remains unknown.

Authors: Fithria Fithria , Wardani Elly , Usman Said , Maulida Rizkia , Darmawati Darmawati , Husna Cut
Published: April 2022

BACKGROUND: The Internet has been a part of life and the development of technology. Internet addiction is one of the problems among adolescents, especially in Indonesia. Family dysfunction is thought to be a factor causing Internet addiction in adolescents. Family cannot always supervise adolescents, and adolescents are required to have good self-control to avoid problematic gaming behavior and online game addiction. If not taken seriously, game addiction can interfere with the physical and mental health of adolescents.

AIM: This study aimed to identify the relationship between family functioning and Internet gaming disorder among adolescents in Aceh. Currently, Aceh is the only province in Indonesia implementing sharia (the Islamic law).

METHODS: This was a quantitative study with a descriptive correlational method. The samples of this study were 157 male senior high school students. This research was conducted from January to April 2021. Data were collected by a self-report questionnaire and analyzed using the logistic analysis to identify the correlation between family functioning and Internet gaming disorder.

RESULTS: The results showed that family functions such as communication functions (p = 0.034), affective engagement (p = 0.006), and behavioral control (p = 0.000) were significantly related to Internet gaming disorders in adolescents. This assumption is evidenced by the results of statistical tests that show a value (<0.05). While the problem-solving function (p = 0.916) and the general function (p = 0.606) obtained a significant value (>0.05) so it can be concluded both of these family functions were not related to Internet gaming disorder.

CONCLUSION: The family functions are significantly related to Internet gaming disorders in adolescents. Maximizing family functions is one solution to prevent Internet gaming disorders in adolescents.

Published: April 2022

BACKGROUND: One indicator of the health of infants and toddlers is an increase in body weight and length/height following age. This fact has attracted the attention of many parties trying to find solutions and innovations, including re-examining the local wisdom of Indonesian culture, which is believed to have been passed down from generation to generation to help increase the baby’s weight and length.

AIM: This study aims to determine the effectiveness of baby massage on increasing a baby’s weight and length in the work area of the Nosarara Community Health Center, Palu City.

METHODS: This type of research was a quasi-experimental research design with pre- and post-test control group design. The population in this study were all infants aged 0−11 months in the Nosarara Health Center’s working area, involving 60 infants; 30 were the intervention group for a month of massage and 30 were the control group. The sampling technique in this study used the purposive sampling method based on certain considerations. The statistical test used was parametric and the paired t-test.

RESULTS: The age of the mother in this study is mostly 28−30 years old, namely, 23.3% with an education level of Senior High School at 63.3% and the mother’s work is Mother’s work, which is 95%. Then, the age of most children aged 4−7 months, namely, 38.3%. There is a difference in children’s weight before and after the intervention where the initial weight is 5.8 kg–6.43 kg after 1 month of intervention. There are differences in the child’s body length before and after the intervention where the initial body length was 56.97 cm–60.03 cm after 1 month of intervention.

CONCLUSION: This study showed no significant difference in the increase in body weight and length of infants between the intervention and the control groups. The average increase of massaged infants was 600 g in weight and 3.01 cm in length. Those who were not massaged were 400 g in weight and 1.26 cm in length.

BACKGROUND: Anticoagulant therapy is recommendation for COVID-19 infection. However, the mechanical ventilation needed for COVID-19 is still high.

AIM: The aim of the study was to determine comparison therapeutic and prophylactic dose LMWH for mechanical necessity in COVID-19 infection.

METHODS: A systematic literature search articles online from studies published between 2020 and 2021 that met our inclusion criteria and were retrieved from scientific databases such as Cochrane, ProQuest, and PubMed. The primary measure was a composite bad outcome, which included mechanical ventilation, mortality. and bleeding risk.

RESULTS: There were 3432 patients from seven study included in this meta-analysis for necessity of mechanical ventilation in COVID-19 patients that used prophylactic and therapeutic anticoagulants. Prophylactic dose of anticoagulant showed no difference for the need for mechanical ventilation necessity for COVID-19 patients (RR = 0.54; 95% CI = 0.20–1.48; p = 0.23). However, prophylactic anticoagulant showed more safe for bleeding incidence (RR = 0.27; 95% CI = 0.18–0.39; p = <0.00001) and reduce mortality (RR = 0.52; 95% CI = 0.46-0.58; p = <0.00001).

CONCLUSION: LMWH anticoagulant dose not associated with reduce mechanical ventilation necessity but prophylactic dose prefers rather than therapeutic dose for reduce mortality and risk of bleeding.

Normal form coordinates for the Benjamin-Ono equation having expansions in terms of pseudo-differential operators
Authors: Kappeler Thomas , Montalto Riccardo
Published: April 2022

Near an arbitrary finite gap potential we construct real analytic, canonical coordinates for the Benjamin-Ono equation on the torus having the following two main properties: (1) up to a remainder term, which is smoothing to any given order, the coordinate transformation is a pseudo-differential operator of order 0 with principal part given by a modified Fourier transform (modification by a phase factor) and (2) the pullback of the Hamiltonian of the Benjamin-Ono is in normal form up to order three and the corresponding Hamiltonian vector field admits an expansion in terms of para-differential operators. Such coordinates are a key ingredient for studying the stability of finite gap solutions of the Benjamin-Ono equation under small, quasi-linear perturbations.
Distributed Bayesian posterior voting strategy for massive data
Authors: Li Xuerui , Kang Lican , Liu Yanyan , Wu Yuanshan
Published: April 2022

The emergence of massive data has driven recent interest in developing statistical learning and large-scale algorithms for analysis on distributed platforms. One of the widely used statistical approaches is split-and-conquer (SaC), which was originally performed by aggregating all local solutions through a simple average to reduce the computational burden caused by communication costs. Aiming at lower computation cost and satisfactorily acceptable accuracy, this paper extends SaC to Bayesian variable selection for ultra-high dimensional linear regression and builds BVSaC for aggregation. Suppose ultrahigh-dimensional data are stored in a distributed manner across multiple computing nodes, with each computing resource containing a disjoint subset of data. On each node machine, we perform variable selection and coefficient estimation through a hierarchical Bayes formulation. Then, a weighted majority voting method BVSaC is used to combine the local results to retain good performance. The proposed approach only requires a small portion of computation cost on each local dataset and therefore eases the computational burden, especially in Bayesian computation, meanwhile, pays a little cost to receive accuracy, which in turn increases the feasibility of analyzing extraordinarily large datasets. Simulations and a real-world example show that the proposed approach performed as well as the whole sample hierarchical Bayes method in terms of the accuracy of variable selection and estimation.

Disabled Military Veteran and Instructor
Authors: Howe William T.
Published: April 2022

In this chapter, the author details personal experiences of transitioning from the military to the college classroom and offers practical advice for interacting with both students and other faculty members in the academy. The author provides practical advice that veteran instructors could use in the classroom as well as when communicating with other faculty members. The author also proposes that those with disabilities be open with both students and faculty members when the disability may impact instructor performance so that accommodations can be made, or awareness can be raised to help the instructor be successful. Using poetry, much of which was written by war veterans, the author attempts to expose the civilian reader to the military mindset so they may have a better understanding of their colleagues and/or students who are military veterans. The author hopes this chapter can serve as a valuable reference to veterans and/or those with disabilities who seek to teach in the college classroom.

Authors: K. S. Archana , B. Sivakumar , Reddy K.V Siva Prasad , C. Arul Stephen , A. Vijayalakshmi , B. Ebenezer Abishek
Published: April 2022

Weed plants are unwanted plants growing in between host plants. There are more than 8000 weed species in the agriculture field. This is the global issue that leads to loss in both the quality and quantity of the product. So, attention has to be taken to avoid these losses and save manpower. In this chapter, the three procedures, segmentation, feature extraction, and classification, for weed plant identification are presented in detail. To separate the region of interest, threshold segmentation method was applied. Then the important features, shape, and textures were analysed with the help of GLCM method, which are discussed in this review. Finally, in the image classification method, modified support vector machine was used to separate the weed and host plants. Finally, this modified SVM was compared with CNN using performance analyses and produced high accuracy of 98.56% compared to existing systems. Hence, the farmers are expected to adopt these technologies to overcome the agricultural problems.

A straight explanation of internet of things denotes the standard internet protocol belonging to human-to-entities and entities-to-entities transmission. Similarly, corporeal entities implanted with RFID, sensor, and so forth permits the entity to interconnect. Comparably, if we see IoT security as more important than the practical problem, we need rules and virtuous security systems. There are several problems in internet of things which burst out of the solution (RIFD tag security, cellular security, grid communication security, seclusion guard, and data handling security). In this chapter, the authors analysed several challenges for secure IoT, security concerns in IoT, and which safeguard the IoT assets in devices and data in contradiction of hacking and stealing. The authors give scrutiny to the challenges integrated in WSN and IoT for ecosystem observing.

Published: April 2022

Education is an essential factor in the development of a nation. We should make it appropriate according to the changing scenario of the country. Learning is an opportunity to reflect upon the social, economic, cultural, and moral issues faced by human beings. Nowadays most of the institutions are working only for a degree, students and teachers are running after attaining or providing degrees, and not towards knowledge and wisdom. A good teacher can bring the entire world to the classroom. The overall scenario of higher education in India does not match the global quality standards. Education has to develop appropriately according to the time and changing scenarios of the world. It contributes to national development through specialized knowledge and skills. So, higher education has to come out of the static environment and become more dynamic and more futuristic. The solution to all the problems is providing quality education, and teachers are the main ingredients in giving quality education.

Authors: Litz David R. , Areepattamannil Shaljan , Parkman Scott H.
Published: April 2022

Research into the effects of out-of-school-time mathematics and science lessons on academic performance has thus far proved inconclusive. The relationship between the two requires investigation to elucidate the benefits of these lessons or lack thereof. Using data from the 2009 Program for International Student Assessment (PISA), this study examined the relationship between out-of-school-time mathematics and science lessons and academic performance among 15-year-olds in Hong Kong, China; Korea; Shanghai, China; and Singapore. In light of different cultural contexts, educational standards, and societal norms, and after accounting for gender and family socioeconomic status, which takes into consideration parents' occupational status, years of education, and home possessions, regression analyses revealed inconsistent results across these countries. The study concludes with the implications of the findings and scope for future research, underscoring the need for further investigation that addresses educational disparities in Asia and globally.
An Assessment of Self-Service Business Intelligence Tools for Students
Authors: Daradkeh Mohammad K.
Published: April 2022

While previous research has mainly focused on improving the technical capabilities of self-service business intelligence (SSBI) tools, very little is known about how students evaluate different self-service BI tools, especially if they have different levels of experience. The goal of this chapter is to understand how students' characteristics influence their evaluation of different self-service BI tools. In this chapter, the authors focus specifically on two important student characteristics: need for cognition (NFC) and innovative cognitive style (ICS). These end-user characteristics were incorporated into a research model developed based on the elaboration likelihood model (ELM). To test the model, a laboratory experiment was conducted with undergraduate students for data analysis and reporting tasks, and the resulting data were analyzed using the partial least squares (PLS) approach. The results showed that the effect of NFC and ICS on the evaluation of SSBI tools varied depending on students' experience and familiarity with the tool.

Published: April 2022

The objective of the research is to use machine learning techniques to evaluate and predict learners' sentiment toward specialty school. The current study used the Yelp website's reviews to obtain data on specialty schools after filtering. Following cleaning, the filtered summary sentences were rated as positive, neutral, or negative sentiments using the AFINN and VADER sentiment algorithms. In addition, to split learner ratings of specialty schools into three sentiment categories, the current study also used four supervised machine learning techniques. The majority of ratings for specialty schools were favorable, according to the findings of the present study. Furthermore, while all of the techniques (decision tree, K-neighbors classifier, logistic regression, and SVM) can accurately classify review text into sentiment class, and SVM outperforms in terms of high accuracy. Specialty educational institutes will be able to better understand learners' psychological sentiments based on the findings of the study, allowing them to improve and adjust their services.
Identifying Structure in Program-Level Competencies and Skills
Authors: Hayes Heather , Trajkovski Goran
Published: April 2022

Programs in an online competency-based higher education (OCBHE) institute will focus on a set of skills and competencies that form a theme throughout multiple courses, where one course builds upon another in terms of increasing the strength or depth of competency. Thus, for students within a given program or major, it is ideal for scores from course assessments with overlapping content to correlate and indicate higher-order skills or competencies. The purpose of this study was to use factor analysis to test the internal and structural validity of course-level performance assessment scores for a group of courses taken as part of a data analytics program in an OCBHE institution. Moreover, the presence of program-level competencies was investigated using hierarchical factor analysis for two groups: a faster, shorter course track and a slow, longer course track. Results supported validity at the course level as well as the presence of a higher-order factor (program-level competency) for the fast course track but not the slow track.
The Secret Lives of ePortfolios
Authors: Collins Samuel
Published: April 2022

This chapter looks at student ePortfolios as a potential resource for graduate careers through text network analysis. The chapter begins with a critical examination of the current state of applicant tracking systems (ATS) and the way they utilize ranking algorithms to reduce graduates to a bundle of fungible skills. As a complementary corrective to these systems, the essay suggests text network analysis of ePortfolios, arguing that this would be one way to hire graduates for the future by opening the possibility for latent networked skills and meanings to re-define jobs. Network applications allow for prospective employers to quickly analyze ePortfolio content and see potential connections and innovations. Moreover, a text network analysis would be one way to develop more team-based approaches that would focus less on the individual than on the way that graduates might combine with each other in innovative teams. ePortfolios emerge here as a way of bringing back complexity into what is fast becoming an entirely automated hiring process.
The Socioeconomic and Political Ramifications of Climate Migration in the 21st Century
Authors: Kaplan Mitchell Alan
Published: April 2022

As the environmental consequences of climate change continue to expand across international boundaries, many nations in the industrialized and developing world are struggling to find ways to cope with the onslaught of adverse social effects caused by this unprecedented phenomenon. Research spearheaded by environmental organizations such as the United Nations and other government-backed climate monitoring agencies suggests that the ecological disruptions caused by the dramatic shift in global weather patterns is one of the primary factors driving the escalation of mass migration and human population displacement in many parts of the civilized world. This chapter will examine the social, economic, and political issues associated with climate-induced migration in the United States and abroad. It will analyze how this phenomenon influences the development of climate policy capable of assisting vulnerable nations worldwide to implement strategic measures that will enable them to resolve the complex national security and border immigration issues associated with the climate crisis.

Authors: Demir Hacer Handan
Published: April 2022

Innovation activities, which have been on a rapid increase, impact countries' degrees of development. Countries that are able to produce and export advanced technology are one step ahead of other countries in terms of international competition. For this reason, exports of high-tech products and related determining factors have become an issue that needs to be addressed. The aim of this study is to examine the determinants of high technology product exports between 2010-2020 for the BRICS-T developing country group using panel regression analysis. As a result of the analysis, GDP and R&D were specified as the most influential variables on exports of high-tech products. A GDP variable of 29.1%, R&D variable 28.9%, FDI variable 16.5%, EMP variable 13.5%, and finally, an ICT variable of 12.8% positively affect high technology product exports in terms of statistics. For developing countries, it is important to improve policies that increase income as well as achieve higher levels of R&D.

Published: April 2022

Wear, plastic deformation, and mechanical fatigue of dies are the most common failures found during hot forming operations at elevated temperatures. The change in frictional behaviour also happens. The performance of the forming operation is affected. To ensure the quality of the end products and productivity, it has become very important to control the wear and friction of die materials. Surface treatment techniques with superior wear properties and good performance can enhance the life and functionality of dies. Plasma nitriding is the most rapidly developing technique for hot forming dies. It is a cost-effective technique and improves the mechanical properties of the die surfaces. This chapter explains the tribology of hot forming dies, the plasma nitriding technique, and the procedures to develop plasma nitriding on the die steels. Thereafter, the tribological behaviour of AISI H11 and AISI H13 plasma nitrided die steels has been reported. Plasma nitriding was found to be most promising and effective in reducing wear and friction at elevated temperatures.

Moving mechanical systems create a lot of friction; therefore, a lot of the energy produced is used to overcome it. It is vital to find unique ways to develop lubricants that allow for more effective control or decrease friction to reach a sustainable future. High friction, if not efficiently reduced or controlled, can result in higher wear losses and, as a result, shorter system life and lower reliability. Two-dimensional (2D) materials have distinct friction and wear properties from their three-dimensional (3D) counterparts. They can be used as additives in oils and composites to reduce stiction, friction, and wear, even though they are ultra-thin even with numerous layers. The role of these materials in superlubricity on surfaces prone to friction and wear is discussed in this chapter. These materials are solid two-dimensional lubricants that can address developing needs in mechanical systems in motion in current and emergent real-world applications.
Morphology and Functionalization of Metal Foils and Other Surfaces for Electrochemical Applications
Authors: Rozman Martin , Lukšič Miha
Published: April 2022

Electrochemical applications had their first major impact in the late 20th century with the development of improved energy storage and conversion systems such as lithium-ion batteries, organic-inorganic dye-sensitized solar cells, and even e-ink displays. Depending on the requirements, the electrodes can be made of different materials, such as metal or alloy sheets, foils, bars or conductive ceramics, conductive polymers, etc. In this chapter, methods for surface functionalization and characterization of metallic and non-metallic surfaces used as electrode substrates are presented. The focus is on the use of metal foils in lithium-ion batteries and especially in the novel architecture of optoelectronic devices – from electrochromic and photovoltaic devices to biosensors.

Published: April 2022

A diagnosis of congenital long QT interval syndrome based on history and electrocardiogram was made in a child in the absence of readily available genetic testing. A genotype 3 (LQT3) was suspected after exclusion of other variants as the child was non-responsive to beta-blocker and sodium channel blocker medication. As the child continues to show episodic bradycardia, polymorphic ventricular ectopy, and T-wave alternans, a single-chamber automated implantable cardioverter-defibrillator implantation was done successfully. This report highlights how the diagnosis of LQT3 was arrived at as well as the anesthetic challenges in the management of patients with LQTS.
Use of Fogarty catheter as bronchial blocker for lung isolation in children undergoing thoracic surgery
Authors: Behera Bikram K , Misra Satyajeet , Mohanty Manoj K , Tripathy Bikasha B
Published: April 2022

Background and Aim:

Various devices such as single lumen tubes, balloon-tipped bronchial blockers, and double-lumen tubes can be used for lung isolation in children, but no particular device is ideal. As such, there is a wide variation in lung isolation techniques employed by anaesthesiologists in this cohort of patients. This study aims to describe our experience with Fogarty catheters for lung isolation in children.

Methods:

This was a single centre, retrospective review of 15 children, below the age of 8 years, undergoing thoracic surgeries and requiring lung isolation. Demographic details, clinical parameters, complications during Fogarty catheter placement, number of attempts for placement, time taken for satisfactory lung isolation, and intraoperative complications were collected.

Results:

Successful lung isolation was achieved in all 15 children with Fogarty catheters of various sizes with the help of flexible bronchoscopy. Desaturation and bradycardia were the commonest complications seen during placement of the catheters but resolved with bag-mask ventilation. On average, 2 attempts were required for successful Fogarty placement. The mean time for successful lung isolation was 6.9 ± 1.3 minutes. The commonest intraoperative complication noted was desaturation, which resolved with an increase in FiO2and positive end expiratory pressure. 2 children had migration of the device proximally to the trachea causing airway obstruction. The devices were successfully repositioned in both cases.

Conclusion:

Fogarty catheters can be used for successful lung isolation in children less than 8 years of age, undergoing thoracic surgery.

Published: April 2022

Background:

Pulmonary regurgitation is imminent after transannular patch (TAP). We analyze the long-term performance of untreated autologous pericardium (UAP) as valve substitute at pulmonary position in patients requiring TAP.

Material and Methods:

This cross-sectional study include patients operated between 2007 and 2012 (n = 92). A sample of 19 patients was selected for this study which had a follow-up of more than 3 years. This includes patients with no TAP (n = 4) and with TAP and valve substitute, a monocusp (n = 11) or a tricuspid valve (n = 4) at neopulmonary annulus. Patients underwent echocardiography for assessment of right ventricle function and 18 fluoro-deoxyglucose PET CT scan for measurements of valve substitute at neopulmonary annulus. The target to blood ratio (TBR) of uptake of glucose by monocusp was measured at the cooptation edge of the neopulmonary valve.

Results:

The median age of the patients is 14 (9 – 37). RV function is preserved (TAPSE 18.9 (10.6 – 22.8)) at a mean follow-up of 4 years (3-9). The measurements of monocusp shows a shrinkage in height of the cusp by 35.5% (70% – 1.0%) and length by 7% (-44% - +104%). There was less shrinkage observed in patients below 15 years of age. The TBR of monocusp was 0.945 (0.17 – 3.35) with a strong correlation between the TBR values of aortic valve leaflet and monocusp leaflet of same patient.

Conclusion:

The UAP is functional and successful as a valve substitute at neo pulmonary annulus at long-term follow-up. It has resisted calcification and has shown uptake of glucose in physiological limits.

Published: April 2022

Infants with hypoplastic left heart are at increased risk of adverse events including mortality when they undergo procedures with general anesthesia in the inter-stage period after stage I Norwood. This is primarily caused by an imbalance between pulmonary and systemic blood flows augmented by decreased function of the single ventricle. These factors can be aggravated by general anesthesia, hence the increased risk. Many of these infants experience feeding dysfunction and require a gastrostomy to optimize nutrition. We report a case of open gastrostomy in an infant with Norwood physiology under spinal anesthesia with an excellent outcome .

Inflammatory pseudotumors (IPs) encompass a wide spectrum of pathological entities of varying nomenclatures such as plasma cell granuloma, xanthomatous pseudotumor, and hypertrophic pachymeningitis. Majority of them are of uncertain etiology. Such tumor-mimicking lesions have been described in the lungs, liver, peritoneum, and retroperitoneal spaces. Primary convexity meningeal occurrence without intracerebral extension or extracranial presence is uncommon. We present one such rare case of a 50-year-old woman having a convexity primary meningeal IP with a 4-year follow-up post-excision.

Radiology of IP may be nonspecific and pathological diagnosis is necessary in most cases to rule out meningeal neoplasms or infections, autoimmune/vasculitic, and other unusual mimics. Although surgical excision is warranted, complete resection may not be necessary if the frozen report is diagnostic. The differential diagnosis and treatment options are discussed further and a flowchart is provided depicting the meningeal tumor mimics.

Published: April 2022

Primary CNS lymphoma (PCNSL) is a rare variant of extranodal non-Hodgkin's lymphoma and accounts for 3%–5% of all primary brain tumors. Their intraventricular location is extremely rare with only a few cases on record so far. All the reported cases showed bilateral ventricular involvement. We report the first case of unilateral lateral ventricle PCNL in a 22-year-old female who presented with intractable vomiting and headaches. Computed tomography (CT) followed by magnetic resonance imaging (MRI) revealed lobulated altered signal intensity lesion in the left temporal horn of lateral ventricle with surrounding peritumoral edema causing midline shift. With these imaging features, the diagnosis of intraventricular meningioma was suggested. Microscopic examination of the excised mass revealed round-to-ovoid tumor cells with scant eosinophilic cytoplasm with large and hyperchromatic nuclei, prominent nucleoli, irregular nuclear membrane, and frequent mitotic figures. The tumor cells are positive for leukocyte common antigen, CD20, CD10, CD43; and were negative for CD3, synaptophysin, chromagranin, pan-cytokeratin (pan-CK), Epstein-Barr virus (EBV), and glial fibrillary acidic protein. The Ki-67 was very high (80%). With these histopathological and immunohistochemistry (IHC) findings, diagnosis of NHL of diffuse large B cell type was rendered.
