Mediating Effects of Social Support and Resilience on the Association between COVID-19-Related Stress and Mental Health in Korean Young Adults
Authors: Noh Dabok , Park Suin
Published: June 2022

Young adults were vulnerable to mental health issues during the COVID-19 pandemic. However, the underlying pathway by which COVID-19-related stress influences mental health outcomes among young adults remains unclear. This study aimed to examine the mediating effects of social support and resilience between COVID-19-related stress and mental health outcomes. A sample of 1000 Korean young adults was obtained via online survey. Participants completed self-report questionnaires assessing COVID-19-related stress, social support, resilience, depression, and anxiety. Overall, 48.1% and 23.4% of participants were classified as having depression and anxiety states, respectively. Path analysis using AMOS version 26.0 (IBM Corp., Armonk, NY, USA) showed that the direct effects of stress from social distancing difficulties on depression and anxiety were much greater than those of stress from fear of infection and anger toward others. In addition, there were significant indirect effects of social support and resilience in the relationship between stress related to difficulties due to social distancing and mental health outcomes. The mediating roles of social support and resilience suggest that interventions to increase these factors can be effective strategies to reduce the risks of depression and anxiety among young adults suffering from stress related to social distancing difficulties.

Published: June 2022

The aim of this study is to evaluate the anaerobic digestion and biogas production of plant biomass under high salinity by adopting a theoretical and technical approach for saline plant-biomass treatment. Two completely mixed lab-scale mesophilic reactors were operated for 480 days. In one of them, NaCl was added and the sodium ion concentration was maintained at 35.8 g-Na+·L−1, and the organic loading rate was 0.58-COD·L−1·d−1–1.5 g-COD·L−1·d−1; the other added Na2SO4–NaHCO3 and kept the sodium ion concentration at 27.6 g-Na+·L−1 and the organic loading rate at 0.2 g-COD·L−1·d−1–0.8 g-COD·L−1·d−1. The conversion efficiencies of the two systems (COD to methane) were 66% and 54%, respectively. Based on the sulfate-reduction reaction and the existing anaerobic digestion model, a kinetic model comprising 12 types of soluble substrates and 16 types of anaerobic microorganisms was developed. The model was used to simulate the process performance of a continuous anaerobic bioreactor with a mixed liquor suspended solids (MLSS) concentration of 10 g·L−1–40 g·L−1. The results showed that the NaCl system could receive the influent up to a loading rate of 0.16 kg-COD/kg-MLSS·d−1 without significant degradation of the methane conversion at 66%, while the Na2SO4–NaHCO3 system could receive more than 2 kg-COD·kg−1-MLSS·d−1, where 54% of the fed chemical oxygen demand (COD) was converted into methane and another 12% was observed to be sulfide.

Dementia was one of the conditions focused on in an EU (European Union) project called “PARADISE” (Psychosocial fActors Relevant to brAin DISorders in Europe) that later produced a measure called PARADISE 24, developed within the biopsychosocial model proposed in the International Classification of Functioning Disability and Health (ICF). The aims of this study are to validate PARADISE 24 on a wider sample of patients with mild to moderate dementia to expand PARADISE 24 by defining a more specific scale for dementia, by adding 18 questions specifically selected for dementia, which eventually should be reduced to 12. We enrolled 123 persons with dementia, recruited between July 2017 and July 2019 in home care and long-term care facilities, in Italy, and 80 participants were recruited in Warsaw between January and July 2012 as part of a previous cross-sectional study. The interviews with the patient and/or family were conducted by health professionals alone or as a team by using the Paradise data collection protocol. The psychometric analysis with the Rasch analysis has shown that PARADISE 24 and the selection of 18 additional condition-specific items can be expected to have good measurement properties to assess the functional state in persons with dementia.

Published: June 2022

Background: The purpose of this study was to measure physical activity (PA), sedentary behavior (SB), and hour-by-hour PA patterns with an accelerometer in a population-based sample of Finnish children and adolescents. Methods: A total of 3274 participants (3rd, 5th, 7th, 9th graders) from 176 schools wore a hip-worn triaxial accelerometer for seven days during waking hours. Mean amplitude deviation of the acceleration data was used to assess PA intensity that was converted to metabolic equivalents and categorized into light, moderate, and vigorous PA. Angle for posture estimation was used to measure SB and standing. Results: The majority of participants’ PA consisted of light PA, and they were sedentary for more than half of their waking hours. Children were more active than adolescents, and boys were more active than girls. Participants took, on average, 9890 steps daily, and one third met the PA recommendation. The participants were divided into tertiles based on daily steps to investigate the variation in PA patterns. Compared to the least active tertile, the most active tertile took twice as many steps on weekdays and nearly three times as many steps on the weekend. Conclusions: The majority of the participants were not active enough, and there was a great variation in PA levels and patterns, especially among the adolescents and on weekends.

Published: June 2022

Monte Carlo simulations can quantify various types of DNA damage to evaluate the biological effects of ionizing radiation at the nanometer scale. This work presents a study simulating the DNA target response after proton irradiation. A chromatin fiber model and new physics constructors with the ELastic Scattering of Electrons and Positrons by neutral Atoms (ELSEPA) model were used to describe the DNA geometry and the physical stage of water radiolysis with the Geant4-DNA toolkit, respectively. Three key parameters (the energy threshold model for strand breaks, the physics model and the maximum distance to distinguish DSB clusters) of scoring DNA damage were studied to investigate the impact on the uncertainties of DNA damage. On the basis of comparison of our results with experimental data and published findings, we were able to accurately predict the yield of various types of DNA damage. Our results indicated that the difference in physics constructor can cause up to 56.4% in the DNA double-strand break (DSB) yields. The DSB yields were quite sensitive to the energy threshold for strand breaks (SB) and the maximum distance to classify the DSB clusters, which were even more than 100 times and four times than the default configurations, respectively.
Physical, Hydric, Thermal and Mechanical Properties of Earth Renders Amended with Dolomitic Lime

Published: June 2022

The global objective of this work was to manufacture resistant and durable (water resistant) earth renders with good thermal insulation. For this purpose, a medium plastic clayey soil from Kôdéni (Burkina Faso), constituted by kaolinite (62 wt.%), quartz (31 wt.%), and goethite (2 wt.%), was mixed with dolomitic lime (up to 6 wt.%) to manufacture earth renders. The mineralogical, microstructural, and chemical characteristics of dolomitic lime, as well as the physical (linear shrinkage, apparent density, and accessible porosity), hydric (water absorption test by capillarity and spray test), thermal (thermal conductivity), and mechanical (abrasion resistance, flexural, and compressive strengths) properties of the earth renders were evaluated. From these studies, it appears that the addition of dolomitic lime induces the formation of calcium silicate (CSH) and magnesium silicate (MSH) hydrates. These CSH and MSH are mainly formed from the pozzolanic reaction between finely ground quartz and the weak silica of kaolinite in basic media. These formed hydrates improve the physical, hydric, thermal, and mechanical properties of earth renders. This improvement is due to the fact that the formed CSH and MSH stick to the isolated particles of the soil, making them more compact. In view of the good mechanical strength and water resistance, as well as the low thermal conductivity, the elaborated earth renders are suitable for habitats with dry climates, such as the Sahel.

El interés es abordar el derrotero del marco normativo electoral local a la luz de las disputas interpartidarias y los clivajes político-ideológicos de la época, aportando una mirada de mediano plazo sobre la percepción de la dirigencia radical-lencinista acerca de la democracia y sus mecanismos.
Izquierda y derecha peronista como categorías de análisis o los 34 días de disputa institucional en torno a la Universidad de Buenos Aires, 1974
Authors: Friedemann Sergio
Published: June 2022

El artículo contribuye al debate acerca de la pertinencia de las categorías de izquierda y derecha para abordar los conflictos intraperonistas de los 60/70 en Argentina. A través de fuentes orales y escritas, se analizan las disputas en torno a las políticas universitarias entre la Universidad de Buenos Aires y el Poder Ejecutivo Nacional a poco de comenzar el gobierno de Isabel Perón. Asimismo, se observan posiciones moderadas, centristas o con pretensión de equidistancia, concluyendo que izquierda y derecha peronista resultan categorías válidas como polos de un continuum más que como expresiones dicotómicas y excluyentes, aún en un contexto de polarización y competencia centrífuga.

Ser ou não ser armorial?
Authors: SANTOS Marília
Published: June 2022

Na segunda metade do século XX, Ariano Suassuna, e um grupo de artistas e intelectuais, lançou um movimento que tinha como objetivo desenvolver uma arte brasileira. De acordo com Suassuna, era necessário buscar a matéria-prima para a criação no interior do Nordeste do Brasil, em aboios dos vaqueiros, cantos das lavadeiras, ternos de pífanos, folhetos/cordéis, xilogravura, tapeçaria, notas rebatidas da rabeca, cantoria de viola. Com base na cultura popular nordestina e no barroco ibérico, mouro, nasceu o Movimento Armorial, que continua exercendo influência na cena cultural, intelectual e artística do Brasil. Esse artigo faz parte de uma pesquisa de mestrado em Música, já concluída. O objetivo é apresentar a história dos primeiros grupos armoriais e discorrer sobre grupos musicais atuais que têm possíveis influências armoriais: oQuadro, SaGRAMA e Quarteto Encore. Com isso pretendemos registrar e difundir esse conteúdo que, embora em estados como Pernambuco permaneça vivo e em transformação, influenciando os processos criativos musicais, é ainda pouco divulgado. E contribuir para a área da História, História da Música e Educação Musical. É uma pesquisa qualitativa, baseada em pesquisa bibliográfica, entrevistas e etnografia.

Mais especificamente, propõe-se que o espraiamento do jogo teve como importante agente motivador os circuitos futebolísticos constituídos por meio de encontros intermunicipais, nos quais, comitivas esportivas, compostas majoritariamente por membros proeminentes das localidades, passaram a cumprir o papel de promover redes de sociabilidades e de cooperação política entre os sócios e os municípios envolvidos com o jogo.
Back to the Basics: Curriculum Reform and Student Learning in Tanzania
Authors: Rodriguez-Segura Daniel , Mbiti Isaac
Published: June 2022

In 2015, the Tanzanian government implemented a curriculum reform that focused instruction in Grades 1 and 2 on the “3Rs”—reading, writing, and arithmetic. Consequently, almost 80 percent of the instructional time in these grades was mandated towards foundational literacy in Kiswahili and numeracy skills. Other subjects such as English were no longer taught. Using student-level panel data, we evaluate the effect of this policy on learning outcomes using a difference-in-differences approach which leverages the variation in the timing of implementation across grade levels and cohorts impacted by the policy. We find that the policy increased learning by around 0.20 standard deviations in Kiswahili and math test scores one year after the start of the reform. Timely teacher training on the new curriculum was associated with even larger effects. Evaluating longer term outcomes, we find suggestive evidence that the reform decreased the dropout rate of children up to four years later. However, this was also accompanied with lower average passing rates in the national Grade 4 examination due to compositional changes as low-performing students became less likely to dropout.

El trabajo de investigación aborda a las diversas empresas que están formalizadas en el régimen tributario MYPE cuya repercusión está en asegurar y afectar a los ingresos al tesoro público, por lo cual se tiene el objetivo de determinar cómo incide la pos-crisis del COVID 19 en la recaudación del impuesto a la renta de las micro y pequeñas empresas. Este análisis surgió a partir de la estimación de la propia SUNAT, antes de la pandemia se estimaba que en nuestro país se evadía alrededor del 50 % en tributos indirectos, un 30% en tributos directos. Para el procesamiento de la información obtenida en las encuestas, primero resaltando que es de tipo correlacional con un enfoque cuantitativo, de diseño no experimental transversal, debido a que la recopilación de información fue en un solo momento, posteriormente dando a conocer la situación de las recaudaciones desde la perspectiva de los contribuyentes, para tal estudio se escogió una muestra de tipo probabilístico estratificado de las empresas de la región de Puno, 300 empresas pertenecientes al régimen MYPE tributario como muestra. Obteniendo como resultado, en la cual la muestra que existe una mediana relación con r=0,619 que significa que tiene una resaltante importancia el impacto ocasionado de la pandemia en lo posterior concerniente a la presión tributaria. Así mismo existe una regular adaptación a la nueva realidad, el cual trae como consecuencias el bajo pago de los tributos donde r=0,343,además las empresas demuestran una regular aceptación del pago de tributos debido a la reducción económica y volatilidad empresarial y finalmente existe una relación positiva alta entre la post-crisis del COVID 19 y la presión tributaria con 0.704, con un nivel de significancia 0,00 menor a 0,05.

Published: June 2022

Ba0.7Sr0.3TiO3 (BST) films on Y-cut LiNbO3 substrates are investigated to realize wide-range tunable BST capacitors. The performances of the BST films are improved by the optimal magnetron sputtering conditions. It is found that the permittivity tunability of the BST capacitor reaches 300% under an applied voltage of 5 V. Moreover, the film has a high dielectric constant 2700 under an applied voltage of 0 V, and the Q value of the BST capacitor exceeds 3000. The results demonstrate that the BST film on the LiNbO3 substrate has potential as a wide-range tunable capacitor for tunable surface acoustic wave filters.
TESTING THE ENEMY RELEASE HYPOTHESIS IN THE INVASIVE FISH AMATITLANIA NIGROFASCIATA (PERCIFORMES: CICHLIDAE) IN MEXICO
Authors: Jiménez-Sánchez Alfredo , Sánchez-Nava Petra , Rodríguez-Romero Felipe , Flores-Nava Belem
Published: June 2022

The enemy release hypothesis (ERH) posits that invasive species are released from their natural enemies in their introduced range, which promotes their successful invasion. In this study, we tested the ERH in a population of the convict cichlid Amatitlania nigrofasciata , an invasive species in Mexico. The ERH predicts that the convict cichlid: a) is not infected by specialist helminth parasites in the introduced range; b) has lower infection parameter values, as measured through richness, prevalence, abundance and diversity of helminths, than a native species-the redside cichlid Cichlasoma istlanum ; and c) is not affected in its condition factor by the abundance of helminths it carries. The convict cichlid was infected by two (33%) specialist helminths relative to the six specialist helminths that infect the cichlid in its native range. The convict cichlid had lower helminth richness and diversity than the redside cichlid. However, the prevalence and abundance of the parasite species varied between the host fish. While the prevalence and abundance of the nematode Rhabdochona kidderi was higher in the redside cichlid, the prevalence and abundance of the trematode Uvulifer sp. was higher in the convict cichlid. The condition factor in both host fish was not correlated with helminth abundance. Our results do not agree with the prediction that the convict cichlid is completely released from specialist parasites, nor with the prediction that this invasive species has lower infection parameter values than the native redside cichlid. However, our results agree with the prediction that the abundance of parasite helminths do not affect the cichlid’s condition factor. More studies are necessary to determine the advantages that the convict cichlid could have in the introduced range when it is infected with a low richness and diversity of helminths.

The paradigm wars and the incompatibility thesis live on: Trends and adequacy in the use of mixed methods research in the Ghana Journal of Development Studies
Authors: Alatinga Kennedy , Abiiro Gilbert A. , Akudugu Jonas A
Published: June 2022

Despite the potential of mixed methods research (MMR) in providing a comprehensive picture of development issues, its pervasiveness and use in development studies is limited. This paper examines the use of MMR as reflected in contributions to the Ghana Journal of Development Studies (GJDS). Based on a rapid review and content analysis of 105 articles, published in the GJDS over the period 2010 to 2017, this paper illustrates there is an inadequate use of MMR among the community of researchers contributing articles to the GJDS. Specifically, only 16 percent of journal articles used MMR, whereas 52 percent and 32 percent used solely quantitative and qualitative approaches, respectively. The huge use of mono-methods and the paucity of MMR in the field of development studies suggest that the ‘paradigm wars’ and the ‘incompatibility thesis’ are not over. Eighty-six percent of articles that reportedly used MMR did not mention the purposes for employing it, explain the typologies of its designs used, the stages, or even the way the qualitative and quantitative data were integrated.

Published: June 2022

It’s known that the efficient operation of electrical appliances used in production significantly improves the quality and quantity of products. Competent control of technological processes is especially important for such a heavy industry as metallurgical production, where one of the most important issues is the optimal control system for electric motors of moving electrodes, which in turn ensures the required dynamics of arc power control and high productivity. The existing arc power control systems do not fully meet the basic requirements, such as insufficient sensitivity of the regulating parameter, speed and reliability of the electrode movement motor control system. The study of electric motor control systems is an important scientific and technical task in this regard. The optimization of the electric motor control system for moving the electrodes of an electric arc furnace based on the use of logic in control is discussed.

Published: June 2022

It is known that alcohol-containing (alcoholic) drinks are more aggressive than water-containing liquids, which is very important to consider when storing them in fired ceramics (dishes, containers), since such dishes should not let liquid through and should ensure long-term storage of the drink without changing its color and taste. Therefore, it is interesting to study the sedimentary silt of the Duruji River and use it to obtain lowtemperature, sintered pottery products that are resistant to water and alcoholic beverages. Obtaining masses of a new composition based on natural raw materials, silt from the Duruji River, was carried out by pouring into plaster molds, drying, firing in electric furnaces and determining water absorption. Based on the sludge of the Durudzhi River, lowquality (III, IV) kaolins of Ukrainian origin and refractory clays, low-temperature, artistic ceramic products with a sintered shard were obtained, characterized by low water absorption and resistance to alcoholic beverages.
About Some Oversite in Technical Terminology
Authors:   Georgian Technical University, Sutidze Liana
Published: June 2022

The struggle against the oversight in some technical terms translated in dictionaries still continues. Russian-Georgian part of the Technical Terminology was published in 1989, several years later after the Georgian- Russian part. Despite the difference in time, both parts seem identical with only few exceptions. The so-called nests are designated to fully show the practical usage of the given term in the technical sphere, with its correct grammatical and meaningful (functional) forms. However, the terms placed in the nests are often not substantively related. It should also be mentioned that these nests are quite voluminous and often require simplification, even at the expense of abbreviating terms and separating terms according to their subject-functional purpose and perception
Selection of Upper Level Reservoir Operating Modes, Taking Into Account the Efficient Operation of Lower Stream Hydropower Plants, on the Example of Rioni HPPs
Authors:   Georgian Technical University, Chokheli Khatia , Khelidze Grigol ,   Georgian Technical University
Published: June 2022

Efficient management of renewable energy sources, including water resources in the context of global warming and tightening environmental requirements, is the most important challenge of our time. Territorial and temporal redistribution of river runoff within the catchment area is essential for energy reservoirs. The regulation of the river runoff by the reservoir which ensures the operation of hydroelectric power plants located in the downstream with high energy performance is discussed. In particular, the selection of the operating modes of the Lajanuri reservoir (upper stage) is presented taking into account the efficient operation of the downstream HPPs (Gumati HPP I, Gumati HPP II, Rioni HPP). The calculations were made for the case of daily regulation of Lajanuri reservoir. At the same time, the one-stage (peak regime) and the two-stage (peak and base regimes) regulation types are discussed. The water balance equation was used for calculations. Based on the results of calculations, it is advisable to operate the Lajanur reservoir in a two-stage mode, which will increase the peak power of the HPP in a dry watery period at the increased power consumption.

Published: June 2022

Abstract—The utility of chipless RFID technology for the identification of 8 materials (7 plastic types and glass) in the recycling chain is examined. We first demonstrate how the frequency response of 8 Circular Ring Resonators (CRR), designed to operate in the 1.5 - 6 GHz band, are used to  encode 8 unique material IDs. Tagged items are then inserted one a time in front of a chipless RFID reader and speed and accuracy of material identification is determined. We demonstrate the ability to correctly identify material type with over 90% accuracy while being 3-16X faster than other methods reported in the literature. Techniques to further improve detection speed at the cost of accuracy are then presented. Finally, future directions of exploration are also discussed.

 Histotripsy is a non-invasive focused ultrasound therapy that uses controlled acoustic cavitation to mechanically disintegrate tissue. To date, there are no reports investigating histotripsy for the treatment of soft tissue sarcoma (STS). This study aimed to investigate the in vivo feasibility of ablating STS with histotripsy and to characterize the impact of partial histotripsy ablation on the acute immunologic response in canine patients with spontaneous STS. A custom 500 kHz histotripsy system was used to treat ten dogs with naturally occurring STS. Four to six days after histotripsy, tumors were surgically resected. Safety was determined by monitoring vital signs during treatment and post-treatment physical examinations, routine lab work, and owners’ reports. Ablation was characterized using radiologic and histopathologic analyses. Systemic immunological impact was evaluated by measuring changes in cytokine concentrations, and tumor microenvironment changes were evaluated by characterizing changes in infiltration with tumor-associated macrophages (TAMs) and tumor-infiltrating lymphocytes (TILs) using multiplex immunohistochemistry and differential gene expression. Results showed histotripsy ablation was achievable and well-tolerated in all ten dogs. Immunological results showed histotripsy induced pro-inflammatory changes in the tumor microenvironment. Overall, this study demonstrates histotripsy’s potential as a precise, non-invasive treatment for STS.
Capacitive Sensing for Magnetic Nanoparticles in Molecular Communication
Authors: Bartunik Max , Reichstein Johannes , Kirchner Jens
Published: June 2022

Molecular Communication provides a solution for scenarios where conventional technologies for data transmission are not feasible due to energy or size constraints. The development and characterisation of sensor devices for information particles as receivers is an essential step to realising Molecular Communication setups. In this work we will present a new device for sensing of magnetic nanoparticles using a capacitor to detect changes in permittivity. The sensor was evaluated regarding sensitivity and a data transmission scenario in a testbed and compared to an inductive sensor. The new sensor device has a significantly higher sensitivity than the reference sensor, allowing for the use of less information particles when transmitting data. However, the impulse response is wider as magnetic nanoparticles are held in the electromagnetic field of the receiver’s capacitor.

The aim of the work was to describe the epidemiological, clinical and therapeutic aspects of peritonitis by gastroduodenal perforation. Patients and methods: the study was retrospective, and descriptive from January 2010 to December 2013.It was carried out in the general surgery department of the hospital of Sikasso (Mali). Patients operated for gastric and/or duodenal perforation were included. The parameters studied were frequency, age, sex, clinical aspects, and treatment, postoperative. Results: The clinical records of 54 patients were collected. Gastroduodenal perforations accounted for 9.2% of digestive perforations. The mean age of the patients was 34.8 years, with a sex ratio =9.8 at the risk of men. The notion of taking non-steroidal anti-inflammatory drugs was found in 72.2%, an ingestion of plant decoction in 18.5%, a history of gastritis in 7.4%, a history of peptic ulcer in 8%. Abdominal pain was present in all patients; vomiting in 19 patients. The average duration of evolution of the symptomatology was 36 hours. On physical examination the most frequent signs were abdominal contracture in 96.2% of patients; a disappearance of prehepatic dullness in all patients. On digital rectal examination Douglas-fir was bulging and painful in 24 patients. X-ray of the abdomen without preparation found pneumoperitonea in 77.7% of patients. An excision, suture plus omentoplasty were performed in 52 patients. Surgical follow-ups were simple in 77.9% patients, with a morbidity of 12.9% and a mortality of 9.3%. Conclusion: Peritonitis by gastroduodenal perforation is a frequent pathology in our context. It can cause a high mortality. Early diagnosis and treatment could improve outcomes.

Fibromatosis colli is a rare, usually self-limiting condition caused by a benign tumor in the sternocleidomastoid muscle. The tumor occurs most often during infancy and can be clinically associated with torticollis. Accurate diagnosis of fibromatosis colli is important to avoid unnecessary invasive interventions. Ultrasound is considered the radiological examination of choice for diagnosis, as it is noninvasive, inexpensive, and has 100% sensitivity. We discuss the case of a one-month old child who presented with a head tilt and had ultrasound imaging that favore diagnosis of fibromatosis colli.

Introduction: In surgical wards, most of the patients of emergency admission present with abdominal complaints, for which laparotomy is indicated in many cases. Sometimes the diagnosis is obvious and can be done by taking a detailed history and careful clinical examination. Objective: To assess the clinical evaluation of non-traumatic emergency laparotomy, a study of 200 cases. Materials and Methods: It is a prospective study. Two hundred cases of nontraumatic emergency laparotomy patients were studied in Dhaka Medical College Hospital during the period of July 2007 to June 2008. Limited investigations dictated by the clinical conditions were done. Plain X-ray abdomen was the most frequently used investigation alone with blood count, serum amylase and ultrasonogram of abdomen. Clinical diagnosis was made depending on clinical findings and the results of investigations. Results: In total, 200 cases of non-traumatic emergency laparotomy, 139(69.5%) were male and 61(30.5%) were female. Among the 200 patients age of them ranged from 12 to 75 years. Most of them were in the age group of 10 to 50 years of age. In acute appendicitis, pain followed by vomiting in 83.33 of cases, whereas in perforation of duodenal ulcer this incidence was only 14.28%.Pain and fever predominates 51.5% followed by severe abdominal pain 47%.The most common diagnosis of this series was acute appendicitis (48%), followed by duodenal ulcer perforation (24%). Ileal perforation (96) and largegut obstruction (5.5%) occupied third and fourth position respectively. Above study shows that males are more affected by acute non traumatic abdominal diseases and undergone laparotomy. Diagnostic accuracy in respect of clinical diagnosis was highest in case of perforated peptic ulcer (91.07%). In case of acute appendicitis, it was 87.5%. In case of intestinal obstruction, it was 88.88%. Conclusion: The inconsistency between clinical diagnosis and peroperative findings can be minimized with more meticulous ....

Published: June 2022

Para-vertebral extramedullary hematopoiesis (PVEH) is defined as an ectopic development of hematopoietic tissue outside the bone marrow. It is a very rare condition, secondary to haematological disorders leading to chronic anemia. The present report describes two cases of chronic anemia patients with paraspinal medullary hematopoiesis and analyzes the clinical manifestations, imaging, pathology, diagnosis and treatment of EMH. In addition, a supplementary review of previously published cases is provided along with a review of the related literature. Computed tomography (CT) of the first case revealed paraspinal masses, and the largest was 6.2x8.0 cm in diameter. Likewise, MIRy of the second patient revealed multiple paraspinal masses in the bottom of the left thoracic cavity, and the largest was measured 10.1x10.5 cm. In conclusion, EMH is a compatible and rare disease, and should be distinguished from other neoplasms.

Published: June 2022

We report the case of a 23-year-old patient with congenital tri-ventricular hydrocephalus of incidental finding during a pretherapeutic workup requested by a comorbid social anxiety disorder with chronic headache and extremity tremor. Discussion: Although the clinical picture is suggestive of a panic disorder, some elements of the observation suggest that the psychiatric symptoms are secondary to the chronic hydrocephalus. These elements are discussed in the light of the existing literature on the links between psychiatric disorders and hydrocephalus and of neuroimaging studies finding ventricular enlargement in patients suffering from anxiety disorders. Conclusion: There are links between hydrocephalus and psychiatric manifestations. A better understanding of these links could shed light on the etiopathogeny of anxiety disorders.

Introduction: Blount disease is an asymmetrical disorder of proximal tibial growth that produces a three-dimensional deformity. Tibia vara is the main component of the deformity. There is general agreement that two clinical forms should be distinguished based on age, infantile and adolescent, with 10 years as the cut-off. Case: We present a case of 11 year old girl admitted to our radiology department with chronic bilateral gonalgia and genu varum evoluting for a year. The clinical examination reveals bilateral varus deformity of the proximal tibia, a palpable prominence or “beaking” of the proximal medial tibial epiphysis and metaphysic. The diagnosis of blount disease has been confirmed on standard radiography. Conclusion: Blount's disease remains a rare disease whose etiology is still unknown, seems to involve hereditary and environmental factors explaining its very particular distribution. Radiological investigations are helpful to the diagnosis by showing medial varus malalignment of the tibial metaphysis. Many angles have been described. A mongthem, the mostuseful are the mechanical tibio-femoral angle, metaphyseal-diaphyseal angle (MDA) of Levine and Drennan, and bony tibial slope.
