Authors: ЕРМАКОВ А.В. , КОЛОМЕНСКИЙ К.Ю. , СОКОЛОВ Н.А.
Published: March 2022

Переход к цифровой экономике порождает новые задачи по модернизации телекоммуникационной системы. Фундаментом этой системы служат сети электросвязи, использующие проводные (wireline) и беспроводные (wireless) технологии, конгломерат которых можно для краткости обозначить нотацией W+W. Практическая реализация концепции W+W позволяет решить ряд актуальных задач по формированию современной телекоммуникационной системы. В статье обсуждается решение двух задач, связанных с повышением надежности телекоммуникационной системы и ускорением процесса реализации новых требований, присущих тем предприятиям, которые прямо или косвенно относятся к субъектам цифровой экономики.

The transition to a digital economy creates new challenges for the modernization of the telecommunication system. These systems are based on telecommunication networks using wireline and wireless technologies, the conglomerate of which can be designated for brevity with the notation W+W. The practical implementation of the W+W concept makes it possible to solve several urgent problems in the formation of a modern telecommunications system. The solutions of two problems are discussed. They are devoted to improving the reliability of the telecommunication system and accelerating the process of implementing the new requirements inherent in those enterprises that are directly or indirectly related to the subjects of the digital economy.

Published: March 2022

В статье приведены данные, полученные на основании анализа литературных источников, посвященных особенностям эпидемиологии, клинических проявлений, диагностики и лечения сифилиса у ВИЧ-инфицированных лиц. Установлено, что инфекции взаимно повышают вероятность передачи и влияют на особенности протекания друг друга. Частота сифилиса среди ВИЧ-инфицированных значительно выше. В большинстве случаев течение сифилиса, его диагностика и ответ на лечение у ВИЧ-инфицированных не имеют особенностей. Однако возможно быстрое прогрессирование заболевания с коротким инкубационным периодом, ранним развитием и наслоением друг на друга симптомов различных стадий. При первичном периоде чаще развиваются множественные, язвенные, крупные, глубокие, плохо заживающие шанкры, псевдотуморозные узлы. Заболевание может сразу начинаться с проявлений вторичного периода, когда чаще возникают симптоматические формы, встречаются проявления злокачественного сифилиса, высыпания атипичного вида, имитирующие различные дерматозы. Третичный сифилис развивается раньше, наслаивается на проявления вторичного периода. Больше вероятность развития нейросифилиса, некоторых висцеральных поражений. При серодиагностике следует учитывать большую вероятность как ложноположительных, так и ложноотрицательных реакций, их поздней позитивности, персистирования, развития серорезистентности. Лечение сифилиса у ВИЧ-инфицированных проводится по стандартным схемам, хотя возможны неудачи и рецидивы.

The article contains information obtained as a result of literature sources analysis related to peculiarities of epidemiology, clinical manifestations, diagnostics and therapy of syphilis in HIV- infected individuals. It was established that two infections mutually increase the probability if transmission and influence the peculiarities of one another’s course. Prevalence of syphilis is significantly higher among HIV-infected persons. Course, diagnostics and treatment response of syphilis in HIV-infected in the majority of cases has no peculiarities. Rapid progression of syphilis after short incubation, early development and overlap of symptoms of different stages is possible though. During primary period multiple, ulcerative, large, profound, slowly resolving chancres and pseudotumorous nodes occur more frequently. Syphilis may initially begin as secondary stage, when cutaneous and mucosal symptoms appear more frequently, can be observed malignant syphilis,atypical lesions that mimic different dermatoses. Tertiary syphilis appears earlier, overlaps the secondary manifestations. Increased prevalence of neurosyphilis and some of visceral manifestations is characteristic. During serological diagnostic one shall take into account an increased probability of false-negative and false-positive reactions, their late positivity, probability of persistence, serofast development. Treatment of syphilis in HIV-infected is carried out accordingly to standard guidelines, but failures and relapses are possible too.

Authors: Санчес Е.А.
Published: March 2022

В статье представлен опыт применения внутридермальных инъекций ботулинического токсина типа А (препарата aboBTX-A) для коррекции первичного локального гипергидроза в нестандартных для этого метода областях (субмаммарной, паховой, ягодичной, лобной, височной и др.).В основу метода положено свойство ботулинического токсина типа А блокировать транспорт ацетилхолина, уровень которого определяет выраженность потоотделения.Гипергидроз (ГГ) – это одна из социально значимых дерматологических проблем. Тяжелыми формами ГГ страдает от 1 до 5% населения Земли, среди них большую часть составляет молодежь. Принципиально новый подход к лечению ГГ стал возможен после появления препаратов ботулинического токсина типа А, внутридермальное введение которых блокирует транспорт ацетилхолина, являющегося медиатором симпатической нейротрансмиссии потовых желез. Как следствие, временно уменьшается или полностью прекращается потоотделение. Положительные результаты применения ботулотоксина типа А (БТА) aboBTX-A для лечения аксиллярного гипергидроза позволили сделать предположение об эффективности ботулинотерапии ГГ других участков тела с повышенным потоотделением, приводящим к дискомфорту и дерматологическим заболеваниям. Для изучения этого вопроса были проведены клинические наблюдения.

The article presents the experience of using intra-dermal injections of botulinum toxin type A (aboBTX-A) for the correction of primary local hyperhidrosis in non-standard areas for this method (submammary, inguinal, gluteal, frontal, temporal, etc.).The method is based on the feature of botulinum toxin type A to block the transport of acetylcholine, the level of which determines the severity of sweating.Hyperhidrosis (HH) is one of the socially significant dermatological problems. Severe forms of HH suffer from 1% to 5% of the World’s population, most of them are young people. A fundamentally new approach to the treatment of HH became possible after the appearance of botulinum toxin type A drugs, which intradermal administration blocks the transport of acetylcholine, which is amediator of sympathetic neurotransmission of the sweat glands. As a result, sweating is temporarily reduced or completely stopped.Positive results of the use of botulinum toxin type A (BTA) aboBTX-A for the treatment of axillary hyperhidrosis allowed us to make an assumption about the effectiveness of botulinum therapy for other areas of the body with increased sweating, leading to discomfort and dermatological diseases. To study this issue, clinical observations were made.

Published: March 2022

Palembang is famous for the Musi River with a length of 460 km. The area along the river border is vulnerable to the impact of floods, this is the same thing that occurs in the Gandus District, which is mostly located on the banks of the Musi River. Analysis of the flood water level profile along the banks of the Musi River, which is affected by the tides is needed to find out how big the impact of flooding in the study area is. It aims to determine the type of tide, the amount of flow discharge, and simulation of river water level. Primary data was taken using a current meter to determine the speed of river flow. Some of the secondary data needed are river channel topographic data, rainfall data for 10 years, channel cross-section data and Musi River level data. The analysis was carried out in the form of a simulation of flood water level with the help of the HEC-RAS 5.0.7 program. The tidal type of the Musi River is based on the results of the study in the form of Diurnal Tide, with a watershed area of 2.2 km2 in Gandus District, the runoff discharge is 280.34 m3/s. The simulation results with the help of the HEC-RAS program obtained an average runoff height on the Musi River border of 2.7 m. The high runoff from the simulation can have a negative impact on the surrounding community, so there needs to be serious handling for flood control.

Published: March 2022

Successful supply chains manage product flows, information and funds to provide a high level of product availability to the customer. The fundamental challenge today is for supply chains to achieve coordination despite multiple ownership and increasing product variety. The objective then is to coordinate business processes from manufacturers, suppliers, transportation, warehouses, distributors, and partners to the customer in such a way that lower costs, shorter production times and product and service quality adapted to customer requirements are achieved. In the present work, a system is created that evaluates the behavior of the supply chain based on quality. To carry it out, focus groups and exploratory factor analysis with varimax rotation are used to compile the main components of quality management in the SCQM supply chain and the set of dependent variables associated with the determining factors. The results show the most valuable key factors and this is an instrument that allows their evaluation. In the development of the research, the review of impact literature is carried out, methods, techniques and tools such as interviews, document review, work with experts, brainstorming, descriptive analysis and exploratory factor analysis, diagrams or control graphs are used.

Penelitian ini dilakukan untuk mengukur tingkat kompetensi literasi digital orang tua murid satuan pendidikan PAUD di Kabupaten Subang. Pendekatan dan metode pelaksanaan penelitian adalah mixed-method, Sekaligus melakukan benchmark terhadap penelitan sejenis sebelumnya mengenai literasi digital orang tua dan pembelajaran daring di tingkat PAUD pada masa normal baru. Hasil penelitian mengungkapkan informasi dari 30 PAUD yang menjadi responden dan mewakili 30 kecamatan yang ada di Kabupaten Subang. Berdasarkan hasil survei diketahui proses pembelajaran daring untuk tingkat PAUD mayoritas belum dilaksanakan menggunakan platform pembelajaran digital, tapi masih menggunakan komunikasi berbasiskan pesan menggunakan media SMS/ WA. Pembelajaran menggunakan platform digital seperti Zoom sudah dicoba oleh beberapa sekolah PAUD namun terkendala rendahnya literasi digital dan sedikitnya waktu yang dimiliki oleh orang tua murid untuk mendampingi anaknya. Hal ini menunjukkan fakta bahwa meskipun hampir semua orang tua sudah biasa menggunakan dan berkomunikasi secara digital menggunakan telefon genggam atau gadget, tapi tidak paham dalam pemanfaatannya untuk pembelajaran. Berdasarkan hasil penelitian tersebut, maka kebijakan dan panduan literasi digital yang akan direkomendasikan harus menitikberatkan pada peningkatan pengetahuan dan kemampuan orang tua dalam mengakses sistem pembelajaran digital, guna mendukung keberhasilan program dan kegiatan pembelajaran, khususnya yang dilaksanakan secara daring akibat masih merebaknya pandemi Covid-19
Early signs of disorders of cardiovascular biomechanics
Authors: Garanin Andrei A.
Published: March 2022

Aim a comprehensive study of disorders of the biomechanics of blood circulation for early diagnostics of atherosclerosis.
Material and methods. The study included 120 people having one of the following risk factors for cardiovascular diseases: smoking, hypertension, Type 1 or Type 2 diabetes. All subjects underwent computer-assisted rheopulmonography, rheovasography, apexcardiography, and direct sphygmography of the major arteries. The functioning of the heart, the arterial wall, the vascular bed of the pulmonary and systemic circulation was evaluated.
Results. Smoking patients mainly had violations of the pulmonary circulation hemodynamics and the biomechanics of the arterial wall of the peripheral arteries due, obviously, to direct damage by nicotine. In patients with arterial hypertension, there was an increase in the work of the myocardium, obviously as a result of the formation of a hyperkinetic type of blood circulation in this disease. Patients with type 1 and type 2 diabetes mellitus were characterized primarily by the development of systolic-diastolic vascular dysfunction, which may be a predictor of the development of angiopathies in the future. In addition, the study of the kinetics of the major arteries revealed violations of the biomechanics of the wall of all vessels under study with risk factors for atherosclerosis. At the same time, it should be noted that more pronounced changes were found in the distal arteries of the muscular type than in the arteries of the muscular-elastic type, which is obviously associated with hemodynamic overloads experienced by peripheral vessels, both as a result of the hydraulic shock that occurs with hyperkinetic type of blood circulation, and the effect of hydrodynamic forces on the vessel wall under the influence of gravity.
Conclusion. Each factor contributes to the development of disorders of cardiovascular biomechanics and hemodynamics. It is necessary to consider changes in the biomechanics of the heart and vascular bed as early manifestations of the circulatory system malfunction with present risk factors for cardiovascular diseases.

Authors: Gataullin Ilgiz G. , Savinova Aigul R.
Published: March 2022

The article presents a clinical observation of a patient with ovarian cancer, stage IIIA according to FIGO (International Federation of Obstetrics and Gynecology), after completing the first-line combination therapy for whom we determined the risk of recurrence using a special software.
The early prediction of the ovarian cancer relapse was based on calculated ARRNO index (Assessment of Risk of Relapse of Neoplasm of Ovary). As initial data the following characteristics were inserted into the program: disease stage according to FIGO, tumor differentiation stage (Grade), hystotype, state of residual tissue on ultrasound examination after the treatment, levels of СА-125 before the treatment, levels of НЕ-4 after the treatment. The ARRNO software calculated the individual risk of relapse in 3 limits: low (0 - 0,39), moderate (0,40 - 0,85) and high (0,86 - 1,0).
Conclusion. The special software for assessing the risk of relapse of ovarian neoplasm proved to be simple to operate and allowed to predict the relapse with high probability.
A new method for adapting the acetabulum for installation of customized implants
Authors: Varfolomeev Denis I.
Published: March 2022

Aim to assess the accuracy and duration of acetabulum adaptation when using the developed method of installing the acetabular components of the hip joint endoprosthesis.
Material and methods. A method and a special device for its implementation have been developed for adapting of the acetabulum with defects. An experimental study was conducted on 3D printed plastic models of pelvic bones of patients with acetabulum defects of type 2A-3B according to the Paprosky classification. In the main group, pelvic bones were treated using the developed method. The control group used Zimmer (USA) hip endoprosthesis kit cutters as well as standard surgical instruments. The accuracy of the pelvic bone treatment was evaluated by the volume of liquid silicone that was poured into the space between the endoprosthesis component and the pelvic bone. The duration of preparation of the acetabulum for cup implantation was assessed using a stopwatch.
Results. The mean duration of pelvic bone preparation for cup implantation did not differ significantly between the groups (p = 0.7). The average volume of solidified silicone in the space between the cup and the pelvic bone model in the main group was significantly less than in the control group (p = 0.02). This indicates a high accuracy of the acetabulum adaptation. Acetabulum wall damage in control group occurred in 5 cases.
Conclusion. The proposed method and the device for its implementation allow you to prepare the pelvic bone for implantation of a customized cup with high accuracy. Its application can simplify the complex revision operations and reduce their invasiveness.

Determination of Way Points Position on Sequencing Leg for Point Merge System
Authors:   PhD Alumni, Department of Air Traffic Control, Faculty of Aeronautics and Astronautics, Eskisehir Technical University, Eskisehir, Turkey, OREN Dr. Alper
Published: March 2022

This paper aims to propose a novel approach to determination of way points position on sequencing leg for point merge system. This research uses the Base of Aircraft Data to analyze the flight efficiency. Although it is not a general rule, it can be said that there is a tendency in practice to design the waypoints in the sequencing leg at equal distances from each other. In general, essentially equidistant waypoints are designed to facilitate the adaptation of airspace users (both pilots and air traffic controllers). However, it does not seem possible to say that this tendency always gives the most appropriate and optimal results in terms of flight efficiency. A scenario that includes four different cases was ideated and was resolved to discover the potential benefits and/or drawbacks of equidistant and non-equidistant interspace of waypoints. The comparison results of equidistant and non-equidistant interspace show that the average reduction of 9,5 percent of total flight time; 12,5 percent of total flight distance in favor one of a non-equidistant interspace, which is Case-4. Moreover, the Case-4 could be a promising solution for sequencing aircraft conveniently in terms of a first come first service (FCFS) rule.

Opportunistic AP Selection in Cell-Free Massive MIMO-OFDM Systems
Authors: Jiang Wei , Schotten Hans Dieter
Published: March 2022

Exploiting the degree of freedom in the frequency domain and the near-far effect among different access points (APs), this paper proposes an opportunistic transmission scheme in cell-free massive MIMO-OFDM systems. The key idea is to orthogonally assign subcarriers among different users, so that there is only one user on each subcarrier. Then, a user is only served by its near APs through opportunistic selection, while the far APs are deactivated to avoid wasting power over their channels with severe propagation losses. Moreover, the number of active APs per subcarrier becomes small due to the opportunistic selection, making the use of downlink pilots and coherent detection feasible. As corroborated by numerical results, the proposed scheme can bring a significant performance boost in terms of both power efficiency and spectral efficiency.

Published: March 2022

In addition to threatening human lives, the recent COVID-19 pandemic has also highlighted how misinformation is plaguing our online social networks. However, privacy and ethical concerns reduce data sharing by stakeholders, impeding data-driven misinformation detection. Current data encryption techniques---providing privacy guarantees on data---cannot be naively extended to inferring text inputs with Deep Learning (DL) models mainly due to inherent non-polynomial operations (which are not encryption-compatible), error introduced by approximate polynomial activations (because they are only valid for a limited range of input values), and error accumulated over stacked encrypted operations of DL classifiers. In this paper, we propose encrypted federated learning (EFL) framework for text-based misinformation detection as a (secure and privacy-aware cloud) service, where classifiers are securely trained in FL framework---which ensures the privacy of training data holders---and later inference is performed on homomorphically encrypted data---which ensures the privacy of clients' data. We evaluate three classifier architectures---Logistic Regression (LR), Multilayer Perceptron (MLP), and the novel encryption-compatible self-attention network (SAN) proposed in this paper---on two publicly available text-based misinformation detection datasets. To reduce the error induced by polynomial activations, we, formally and empirically, show the efficacy of L2 regularization while training the classifier. To regulate the error accumulated due to cascaded operations over encrypted data, we advocate the use of sigmoid activation with formal proofs and empirically validate our claims. In our case, by simply replacing ReLU activation with sigmoid, we were able to reduce the output error by 1750 times in the best case to 43.75 times in the worst case.
TENSORESISTOR-BASED TELEMETRIC STRAIN-GAUGE LENS-LESS DETECTORS AS SPECIALIZED LABS-ON-A-CHIP FOR SOIL MECHANICS AND FOUNDATION MONITORING
Authors: Orekhov Theodor , Gradov Oleg V
Published: March 2022

A current trend in the development of the applied
measuring techniques is the design of integrated analytical systems on a chip,
in particular, labs on a chip based on various physical principles of the
substance analysis. Recently, the term "lab-on-a-chip" implied
analytical microsystems, requiring macro-scopic readers for the data obtained,
which strongly limited the possibilities of their introduction into the field
studies and routine analytical measure-ments. However, a progress in the design
of telemetric labs on a chip, in-cluding those capable of broadcasting the
analytical signal to the receivers with positional sensitivity provided by the
use of the labeled counting cham-bers, made it possible to use such devices
beyond the scientific laboratories: in the field practice or in monitoring of
the natural systems and artificial structures. This can be applied not only to
the chemical and biological field measurements, but also to the mechanics, in
particular, to geomechanics or soil mechanics. This work briefly considers the
results obtained in the Rus-sian laboratory of the second author during the
period up to 2011-2013, which have not been published earlier due to the
know-how restrictions.

Introduction. The novel coronavirus infection COVID-19 is a major public health problem worldwide. Several publications show the presence of gastrointestinal (GI) symptoms (nausea, vomiting, and diarrhea) in addition to respiratory disorders.The aim of this study was the monitoring of RNA of COVID-19 pathogen, coronavirus SARS-CoV-2 (Coronaviridae: Coronavirinae: Betacoronavirus; Sarbecovirus) in children hospitalized with acute intestinal infection (AII), with following molecular-genetic characterization of detected strains.Material and methods. Fecal samples of children with AII hospitalized in infectious hospital of Nizhny Novgorod (Russia) in the period from 01.07.2020 to 31.10.2021 were used as material for the study. Viral RNA detection was performed by real-time polymerase chain reaction (RT-PCR). The nucleotide sequence of S-protein gene fragment was determined by Sanger sequencing.Results and discussion. SARS-CoV-2 genetic material was detected in 45 out of 2476 fecal samples. The maximum number of samples containing RNA of the virus occurred in November 2020 (detection rate of 12.2%). In 20.0% of cases, SARS-CoV-2 RNA was detected in combination with rota-, noro-, and adenoviruses. 28 nucleotide sequences of S-protein gene fragment complementary DNA (cDNA) were determined. Phylogenetic analysis showed that the studied SARS-CoV-2 strains belonged to two variants. Analysis of the S-protein amino acid sequence of the strains studied showed the absence of the N501Y mutation in the 2020 samples, which is a marker for variants with a high epidemic potential, called variants of concern (VOC) according to the World Health Organization (WHO) definition (lines Alpha B.1.1.7, Beta B.1.351, Gamma P.1). Delta line variant B.1.617.2 was identified in two samples isolated in September 2021.Conclusion. The detection of SARS-CoV-2 RNA in the fecal samples of children with AII, suggesting that the fecal-oral mechanism of pathogen transmission may exist, determines the necessity to optimize its monitoring and to develop an algorithm of actions with patients with signs of AII under the conditions of a novel coronavirus infection pandemic.

Published: March 2022

The aim of the present study was to develop and validate a HPLC method for assaying candesartan cilexetil (CAND) in powder preparations prepared from Blopress® Tablets 2 mg. A chromatographic system comprising a YMC AM12S05-1506WT column, the mobile phase of CH3CN:H2O:HClO4:NaClO4=700:300:1:5 (V/V/V/W), a flow rate of 1 mL/min, and a UV detector set at 254 nm was used. The retention time of CAND was approximately 8.8 min. A regression analysis revealed that the calibration curve of the method was linear in the range of 0.10 to 80 µg/mL. Intra-day precision and accuracy ranged between 0.1 and 1.6% and between -0.4 and 20.9%. The accuracy value at 0.10 µg/mL was 20.9%. Inter-day precision and accuracy ranged between 0.2 and 3.0% and between -0.3 and 20.6%. The accuracy value at 0.10 µg/mL was 20.6%. In both cases, accuracy values at 0.10 µg/mL were out of the range of -10% to 10%. Therefore, the limit of quantification was established to be 0.10 µg/mL. The content of Blopress® Tablets 2 mg was 99.20 ± 0.81% (mean ± SD, n=3). The ratios of CAND in powder removed from the mortar, remaining on the mortar and pestle surface, and scattered on the paper to total recovery were 85.48 ± 3.50, 14.27 ± 3.53, and 0.30 ± 0.02%, respectively.

Published: March 2022

Schnyder crystalline corneal dystrophy (SCCD) is a rare hereditary corneal pathology, the clinical forms of which can be varied. It is classically characterized by the presence of central corneal disc or ring opacities, with or without the presence of crystals, and sometimes the association with a peripheral corneal arch or the limbic belt of Vogt. Its pathogenesis is linked to an abnormality in lipid metabolism with accumulation of lipids (phospholipids or cholesterol) in the cornea. We report the case of a 30-year-old patient, with no particular history, presenting a progressive decrease in visual acuity linked to central corneal opacities, in disc form following an accumulation of iridescent crystals in the central portion of the stroma, with a peripheral lipid arc all evolving for 15 years, and we describe its aspects in anterior segment optical coherence tomography and in vivo confocal microscopy. The purpose of our case is to recall the clinical and biological characteristics of Schnyder crystalline corneal dystrophy, and to underline the risk of occurrence of diffuse vascular damage secondary to a lipid disorder favoring cardiovascular accidents. Ophthalmologists should be aware of the ocular and general signs of Schnyder's dystrophy in order to preserve functional visual and vital cardiovascular prognosis.

Objective: The study was carried out to produce the short-term prognosis of decompensated Liver Disease through the Child-Pugh scoring system and as the complications of cirrhosis and to find out the eligible Percentage of patients for liver transplantation suffering from advanced liver disease. Methodology: This cross-sectional prospective shady was conducted in two best institutes of Bangladesh (DMCH and RSMMU) from January to June 2010. The target population for this study was patients with chronic liver disease in the decompensated state. The patient was selected by meticulous history and clinical examination, including stigmata of chronic liver disease and decompensation, especially ascites, edema, hematemesis melaena, and hepatic encephalopathy. The ultrasonography evidence of coarse echogenicity and Albumin: Globulin ratio alteration was recorded as chronic liver disease evidence. Investigation such as serum bilirubin serum albumin, prothrombin time, ultrasonography of the whole abdomen, the viral market was done in all cases. If the patients are compensated states or decompensated signs explained by any other illness were excluded from the enrollment, 50 patients were randomly selected, and the child Pugh scoring was done within 24 hours of hospitalization. The study physician followed the patients daily up to discharge or death, whichever comes first. Result: In this study, the maximum age incidence among the decompensated CLD patients was between 46-55 years (36%), and the male-female ratio was 4.55:1. Among 50 patients, 64% of patients fall in the Child-Pugh class C group, 28% fall in the class B group, and only 8% fall in the class A group. In the first three months of the study period, death occurred in 37.5% in class C₂ 14.28% in class B and 0% in class A. Overall, death occurred in 14 patients out of 50 patients (28%). In total, 46 patients out of 50 have Esophageal varix. The most frequent presenting symptoms in different Child-Pugh classes are .....
Tracking Atrial Fibrillation by 24-Hour Holter ECG in Ischemic Stroke of Unclear Origin, an Experience of the Cardiology Department of the University Hospital of Marrakesh

Background: Stroke is a worldwide growing health problem; a significant proportion of acute ischemic strokes occur as the first manifestation of atrial fibrillation. We sought to evaluate the performance of 24-hour rhythm monitoring in detecting paroxysmal atrial fibrillation. Methods: This was a cross-sectional study conducted at the University Hospital of Marrakech, in 174 selected patients with ischemic stroke without clear etiology at baseline subjected to ambulatory Holter monitoring. Results: The overall detection rate for atrial fibrillation was 4.1%, allowing the initiation of anticoagulant therapy in selected patients. Nevertheless, although some degree of success in detecting AF in a short period of monitoring was achieved, it is believed that the prevalence of AF is still underestimated by this screening modality. Conclusion: Tracking atrial fibrillation is a fundamental element in the secondary prevention of stroke; the development of new digital technologies now makes the possibility of long-term heart rhythm monitoring accessible. Numerous ECG recording solutions have been scientifically proven reliable, some are already recommended for the detection of cardiac arrhythmias. The choice of the screening method must be tailored to each individual case.

Introduction: Miliary tuberculosis is an increasingly rare form (2% to 8%), defined by the hematogenous or lymphatic dissemination of the tubercle bacillus from a pulmonary or extra-pulmonary focus but which remains serious and can lead to acute respiratory failure due lesional pulmonary edema. Patients and Methods: This is a retrospective study of 101 cases of miliary tuberculosis hospitalized between January 1989 and July 2019 in the pneumology department of “20 Aout” in Casablanca. Results: The average age is 43 years with a predominance of men (64%), the history of tuberculosis is found in 8 cases and tuberculosis contagion in 10 cases. The common symptom in all cases (100%) is an alteration of the general condition, fever is present in 76% of cases, dry cough is found in 75.5% of cases and dyspnea is found in 38.3% of cases. Among the causes of immunosuppression, we noted: 3 cases of neoplasia, 5 cases of diabetes, 5 cases of pregnancy and 4 cases of system diseases. The chest X-ray (frontal view) found an aspect of pulmonary miliaria in all cases associated with pleurisy in 18 cases, an excavated opacity in 3 cases and pneumothorax in 1 case. Tuberculin intradermal reaction (tIDR) was positive in 35 cases. Antibacillary treatment was started urgently in all cases. The outcome was good in the majority of cases with 10 deaths. Further work-up allowed confirmation of the diagnosis either by direct isolation of the koch bacillus or by biopsy in 47.52% of cases.

Gastrointestinal stromal tumor is, by definition, a mesenchymal tumor that develops at the expense of the digestive tract. Quite rare, represents 0.1-3% of gastrointestinal malignancies. These tumors are more commonly located in the stomach or small intestine than elsewhere in the abdomen. They are derived from Cajal cells or a precursor thereof, and are typically of the CD117 / KIT + (95%) and DOG-1 + (95%) phenotype. They very frequently exhibit activating mutations of the genes encoding the KIT or PDGFRA tyrosine kinase receptors. They can occur at any age, but mainly in middle-aged and elderly people. We report the case of a 59-year-old patient with a history of femoroiliac thrombosis treated by implantation of a prosthesis in 2018 with long-term antiplatelet therapy, morbid obesity operated on in 2020, the procedure consisted of Sleeve gastrectomy, hyperparathyroidism on a single lower left adenoma, resected with good control of PTH postoperatively. The patient was known to have a gastric lesion that could not be resected during the sleeve gastrectomy. Monitoring showed stability in size of the gastric lesion on endoscopic control, hence the decision to perform a surgical exploration with an intraoperative endoscopy before deciding on the nature of the procedure to be performed on the gastric stump. The procedure consisted of an atypical resection of the tumor with satisfactory endoscopic intraoperative control. The patient progressed well postoperatively, discharge on analgesics at day 3 postoperative.

Background: Prolapse of lumbar intervertebral discs (PLID) is one of the major causes of morbidity in the arena of orthopedics. Back pain or sciatica which is associated with PLID is now very common among adult population. More cautious assessment must be done to treat such patients. As a treatment method, discectomy is being used widely in treating primary and recurrent prolapse of lumbar intervertebral discs. We have very few research-oriented data regarding the effectiveness of discectomy in treating PLID. Aim of the study: The aim of this study was to assess the effectiveness of discectomy in treating PLID. Methods: This was a prospective observational study which was conducted in the department of Orthopedics, Holy Family Red Crescent Hospital Dhaka Bangladesh during the period from January to December 2019. Purposive sampling method was used in selecting study subjects. Written informed consents were taken from all the participants before data collection. In total 76 patients were included in the study as study population. All data were processed, analyzed and disseminated by using MS Office and SPSS version 23 as per necessity. Results: Among all the participants, the male-female ratio was 1.8%1. The majority portion of patients, 47% was aged between 30-39 years. Among half of total patients (n=38) radicular pain was found. Besides this, 25 had low back pain and the rest 13 patients had lower extremity numbness. Among majority of the participants, left side was involved. Besides this, among 39% patients right side and among 7% bilateral side was involved. As the final outcome regarding the severity of pain it was found that, after surgery among 93% patients occasional back pain was associated and 7% patients were fully free from pain. Conclusion: Discectomy method may be considered as an effective treatment procedure in treating patients with prolapse of lumbar intervertebral discs. But proper assessment of PLID and its situation is a vital part before ......

Published: March 2022

Tuberculosis is a significant health problem in developing countries. Splenic tuberculosis usually occurs as a part of miliary tuberculosis but isolated splenic tuberculosis is very rare. We are reporting the case of a 63 years old immunocompetent female who presented to us with complains of dull aching pain in left hypochondrium and left flank for three months and fever for two months. Laboratory data provided no diagnostic information. Abdominal ultrasonography revealed massive splenomegaly. As spleen was massively enlarged and there was risk of rupture, splenectomy was carried out. From histopathological examination final diagnosis of splenic tuberculosis was made.
