Situs inversus totalis in an asymptomatic adolescent - importance of patient education: A case report
Authors: Hayashi Lauren C. , Acharya Ratna
Published: December 2023

BACKGROUND

Situs inversus totalis (SIT) may be an incidental finding in asymptomatic children. Patients may not understand the implications of this condition and the importance of relaying the diagnosis to their healthcare providers.

CASE SUMMARY

We report an asymptomatic seventeen-year-old adolescent with previously-diagnosed SIT who presented for a routine well-child visit. During history taking, he denied any past medical conditions, including cardiovascular conditions. Only when physical exam revealed point of maximal impulse and heart sounds on the right side, did he convey that he had been diagnosed with SIT incidentally at age of 12 years. He was not aware of associated conditions or the potential implications of his diagnosis, nor did he realize it is pertinent medical history to be relayed to healthcare providers. Chest X-ray confirmed dextrocardia and abdominal X-ray showed right-sided stomach. Abdomen sonogram showed left-sided liver and right-sided spleen. Echocardiogram showed normal valvular structure and function. A comprehensive discussion was provided to address the patient’s lack of understanding that SIT is a medical diagnosis with potential implications.

CONCLUSION

While SIT is rare and mostly asymptomatic, affected patients may not comprehend the importance of the diagnosis and its potential ramifications. Recognition of the patient’s lack of awareness allows the healthcare provider to educate the patient and hopefully can prevent potential medical and surgical complications.

Chest trauma is a significant public health concern, accounting for 15-20% of all trauma-related deaths. The purpose of this study was to examine chest injuries resulting from blunt trauma, with a focus on autopsies. The study aimed to evaluate the epidemiological characteristics of the victims, including their age, gender, and the type of trauma they experienced, as well as identify the leading causes of mortality in these cases. The study was conducted at the Department of Medicine at MTI, LRH, from March 2020 to March 2021 and examined 112 blunt trauma patients. The study collected comprehensive epidemiological data on the victims, including their age, gender, type of trauma, injuries, and other relevant case-related factors. A thorough form was created to record the historical and epidemiological data systematically. The study carefully examined every deceased person, including both external and internal injuries, as well as a detailed evaluation of the thoracic region's bones and joints. The average age of the victims was 31.7±5.41 years, with 16 (14.3%) in the age range of 1-20 years, 62 (55.5%) in the age range of 21-40 years, 18 (16.1%) in the age range of 41-60 years, and 16 (14.3%) in the age range of over 60 years. Of the 112 cases examined, 80 (71.4%) were related to road traffic accidents, 14 (12.5%) were falls from height, 12 (10.7%) were assaults, and 6 (5.4%) were miscellaneous incidents. Male victims constituted 92 (82.1%) of the cases, while female victims were 20 (17.9%). Motorcycles were the most common type of vehicle involved in road traffic accidents, accounting for 72 (64.3%) of the cases. In most cases, the survival rate was less than six hours, with 76 (67.9%) cases falling into this category. The primary causes of death were shock and bleeding, followed by suffocation and coma. In conclusion, the study found that road traffic accidents were the most common cause of chest injuries, likely due to the prevalence of automobiles. Shock and bleeding were the leading causes of death, followed by suffocation and unconsciousness. Most victims had a survival rate of less than six hours.

Air pollution constitutes a pressing worldwide public health issue, and Pakistan is the fourth most polluted country, where nearly 99% of its populace breathes in the air quality that exceeds the WHO criteria. Embracing WHO-endorsed strategies can help in extending life expectancy by five years. This investigation was designed to delve into the factors influencing self-care behaviors and practices regarding air pollution based on Health Belief Model among undergraduate students. Methods: A questionnaire based on the Health Belief Model was used to conduct a cross sectional study on undergraduate students from Rawalpindi, Pakistan about their self-care and protection practices against air pollution. The questionnaire had seven sections and was validated. Non-probability convenience sampling was used. SPSS 26, Spearman’s correlation, and linear regression were used for data analysis. Results: The study enrolled 292 university students, with 189 (64.7%) being male and 103 (35.3%) females, and a mean age of 21.07±1.896. Findings revealed that 22.6% of respondents exhibited satisfactory self-care behavior, while 77.4% exhibited suboptimal behavior. In terms of self-care preventive practices, 58.6% scored poorly, with only 41.4% demonstrating good practices. Conclusions: The study's outcomes demonstrated poor self-care and protection practices among the participants. Factors such as perceived severity, perceived benefits, self-efficacy, and cues to action significantly influenced preventive behaviors. Whereas, perceived susceptibility and barriers were found insignificant. These findings underscore a notable association between Health Belief Model constructs and students' adoption of preventive measures against air pollution.

Bleeding from ruptured arteriovenous fistulae (AVF) is a distressing complication resulting from multiple factors and can lead to life-threatening hemorrhage. Objective: To analyze factors that contribute to the development of a bleeding ruptured AVF which could enable us to make decision regarding line of management for saving these AVFs. Methods: This cross-sectional study was conducted at Department of Vascular Surgery, Sindh Institute of Urology and Transplant (SIUT), including 52 patients presenting with burst arteriovenous fistula during the time period of six months. Data collection was carried out using a pretested questionnaire which comprised of detailed history regarding pre-operative and per-operative factors related to burst fistula. Results: The mean age of the patients was 35.7 ± 19.6 years with gender distribution identified as male (51.9%) and female (48.1%). The major outcome of the study was salvageability of AVF which was observed to be 36.5% among the study cohort. We also analyzed association of AVF salvageavility with pre-operative and intraoperative factors which showed its significant association with risk factors such as fistula age (<40 or > 40 days), area of surrounding inflammation, overlying skin, bleeding AVF before initiation of hemodialysis from fistula, type of cannulation, site of bleeding from AVF and ligation/repair status of fistula. Conclusions: Understanding these significantly associated factors could contribute to the early detection and allow measures aimed at averting adverse outcomes, which can span from the loss of vascular access to severe health problems and even, in some cases, prove fatal.

Published: December 2023

Ce travail est consacré à la mise en évidence par simulation numérique des caractéristiques d’une flamme de diffusion turbulente avec co-courant d’air de méthane enrichie avec de l’hydrogène. La configuration adoptée est constituée d’un mélange de méthane et d’hydrogène dilué dans de l’azote. Elle est caractérisée par des rapports de densité et de vitesses élevés à l’injection. Pour les calculs, la turbulence est modélisée avec l’approche RSM (Reynolds Stress Model) et l’interaction chimie turbulence est représentée par le modèle EDC (Eddy Dissipation Concept). Les caractéristiques de la flamme (longueur, épaisseur, maximum de température, quantités de CO et CO2 produites) sont prédites avec une bonne précision. Dans la première section radiale de la zone proche de l’injection, les maximums de température et de la fraction massique de H2O sont calculés correctement. Par ailleurs, du fait de la présence de forts gradients de densité et de vitesses à l’injection, l’entraînement est sous-estimé et l’épanouissement radial des profils de température et des espèces chimiques est surestimé. Dans les autres sections, les résultats sont en bon accord avec les mesures.
Asymmetric SPWM used in inverter grid connected

Published: December 2023

The overall efficiency of grid-connected photovoltaic power generation systems depends on the efficiency of the DC-into-AC conversion. Therefore, a key consideration in the design and operation of inverters is how to achieve high efficiency with power output. This paper presents a concept of an inverter for grid connected photovoltaic arrays which can synchronise a sinusoidal current output with a voltage grid. Asymmetric PWM inverters can generate power at unity power factor, this approach, based on the active filter is proposed in this work. This method is used in order to correct the phase between the output current and the grid voltage and to maximize the system efficiency in design and control. The functional structure of this system is presented and simulated. Detailed analysis, Simulations results of output voltage and current waveform demonstrate the contribution of this approach to determinate the suitable control of the system. A digital design of a generator SPWM using VHDL is proposed and implemented on an Xilinx FPGA.

Authors: Tamene Youcef , Abboudi Said , Bougriou Cherif
Published: December 2023

On propose une étude numérique, par différences finies, du transfert de chaleur dans un mur multicouche (à deux ou trois couches) soumis à une condition de rayonnement solaire sur le côté extérieur et prenant en compte les échanges de chaleur par convection sur ses deux faces. L’exploitation du code numérique est développée sur des cas relatifs au problème posé dans l’habitat. Les résultats numériques sont présentés sur des exemples de matériaux utilisés dans le domaine du bâtiment dans des conditions réelles de fonctionnement (flux solaire, pertes convectives, etc…). On analyse également, l’influence, sur le transfert de chaleur, de quelques paramètres clés du système comme le choix des matériaux, l’optimisation de leur épaisseur et également la nature variable du flux solaire. Une proposition optimale sera dégagée de cette étude en fonction des objectifs recherchés.
Modeling of polycrystalline N+/P junction solar cell with columnar cylindrical grain
Authors: Trabelsi Abdessalem , Zouari Abdelaziz , Ben Arab Adel
Published: December 2023

Analytical expressions for short-circuit and dark current densities are derived for a polycrystalline N+/P junction solar cell. A new solution of the continuity equation for the minority carrier which is adaptable with the boundary conditions when the cell is either illuminated or in the obscurity is given. For the first time, a three-dimensional model is developed for a polysilicon solar cell with multi-cylindrical grains. For an elementary solar cell, the results show that the three types of recombination such as the bulk recombination, the surface recombination and the recombination at the grain boundaries have an important effect on the cell parameters; and in some cases, one of these forms of recombination dominates the others. In the case of multi-cylindrical grains, the results of our approach show a decrease of the photovoltaic parameters according to the grain number especially for a thick solar cell. In addition, the comparison between an elementary cylindrical grain solar cell and an elementary cubic grain one shows an enhancement of the photovoltaic parameters for the cylindrical model.

De plus en plus dans nos cités, la gestion des ordures ménagères et des déchets industriels pose des problèmes à multiples portées: environnementales, hygiéniques,... Le recours à la digestion anaérobie comme outil de traitement des déchets présente de nombreux avantages: il permet de produire une énergie renouvelable, le biogaz; évite les émissions de carbone dans l’atmosphère et la pollution de l’environnement en tant que tel; et enfin contribue au développement de l’agriculture (production d’engrais). Le présent travail consiste en l’étude de l’effet de l’ensemencement sur la digestion anaérobie des déchets ménagers de la ville d’Adrar à l’échelle du laboratoire en vue de produire du biogaz. Les résultats obtenus montrent clairement que l’effet de l’ensemencement sur la digestion anaérobie des déchets ménagers est très important pour la production de biogaz et la diminution de la charge organique du substrat.
