Introduction: Cytomegalovirus (CMV) infection is present in a latent state in 70–90% of the immunocompetent population, and its reactivation might be triggered by inflammatory conditions such as post-COVID multisystem inflammatory syndrome (MIS-C) or by immunosuppression induced by steroids. The aim of this paper was to highlight the unexpected complications associated with SARS-CoV-2 infection that require a complex clinical approach for accurate diagnosis. Materials and Methods: We present the case of a 4-year-old male patient who, during an initially favorable course of PIMS, experienced symptoms of respiratory failure. Results: The patient initially presented with clinical and paraclinical signs of PIMS with cardiac involvement, for which high-dose corticosteroid therapy was initiated, followed by gradual tapering, along with immunoglobulins, anticoagulants, antiplatelet agents, and symptomatic treatment. After 10 days of favorable progress, the patient's general condition deteriorated, showing tachypnea, desaturation, and a ground-glass appearance on thoracic CT. Negative inflammatory markers and favorable cardiac lesion evolution ruled out MIS-C relapse. The presence of anti-CMV IgM antibodies and viral DNA in the blood confirmed acute CMV infection, likely triggered by prior severe-acute-respiratory-syndrome-related coronavirus 2 (SARS-CoV-2) infection and secondary immunosuppression due to steroids. Non-specific immunomodulatory treatment was initiated but led to worsening of pulmonary lesions, prompting the initiation of specific antiviral treatment with ganciclovir, resulting in rapid clinical and imaging improvement. Conclusions: CMV infection can be reactivated by immunosuppression induced by corticosteroid therapy for MIS-C and may require specific etiological treatment. [ABSTRACT FROM AUTHOR]

The paper presents the essential theoretical elements related to the construction and operation of numerical control machines, starting from a study of the theoretical aspects related to the design of a CNC typewriter. The block diagrams of the machine, the interconnections between the component blocks and the operation of the whole system are highlighted. The paper also describes the implementation of the typewriter. It starts from a detailed diagram of the wiring and connections between the component elements, up to the presentation and commentary of how to create the program for the microcontroller used. Finally, the testing and operation of this CNC is detailed, from the design of the drawing to its actual realization, with the help of the designed and implemented assembly. CNC systems allow the repetitive production of the same parts, exactly the same and without deviations. Unlike a human operator who cannot execute two identical parts, the repeatability achieved by machines with numerical controls is clearly superior, so the reproducibility component is ensured.

The objective of this paper is to develop the control system for driving a mobile robot using the Arduino board, controlled by an ESP 32 logic processor, named SPIDER4LEGS. In order to be used in the oil and gas industry, for example for the internal inspection of oil product transport pipelines, the four-legged spider type robot version was chosen, especially due to the special mobility it offers. The created control system must ensure the control of the movement of the kinematic couplings in the construction of the legs, the monitoring and maintenance of stability as well as the establishment of the optimal stepping sequences. The control system is simple and it use the Wi-Fi communication, because it is the best way to transfer data between the robot and the operator, offering a lot of advantages. [ABSTRACT FROM AUTHOR]

Introduction: Influenza virus infection remains a significant global health concern, primarily affecting the respiratory system. However, emerging evidence suggests its potential to trigger systemic complications, including myocarditis, a condition characterized by inflammation of the heart muscle. Although myocarditis stemming from influenza is uncommon, it poses a significant clinical burden due to its varied presentations and potential for severe consequences. Case Report: We report the case of a six years old girl, admitted in our clinic for respiratory infection with influenza A virus complicated by myocarditis, intrainfectious myositis, acute dehydration syndrome, minimal pericarditis and thrombocytopenia. The onset was 5 days prior to admission fever, vomiting, and headache. Following a negative combined viral antigen test, symptomatic treatment was initiate at home. During the course of the illness, fever and vomiting improved, but the patient developed fatigue, diarrheic stools, and muscle pain in the lower limbs. A combined SARS-CoV-2, influenza, and RSV test returned positive for influenza A, while the laboratory tests indicated elevated cardiac enzymes and liver transaminases, raising suspicion of myocardial involvement. Following emergency cardiology consultation and specialized investigations (ECG: heart rate 100 bpm, flattened T waves in DIII, aVF, V3, negative T waves in V1, V3; echocardiography: apparently good global contractility, minor tricuspid insufficiency), the patient was admitted to the Pediatrics clinic for further investigations, monitoring, and specialized treatment. On 1stday of admission, a cardiology reevaluation recommended the initiation of treatment with spironolactone, along with symptomatic treatment (liver protectors, and rehydration solutions). The patient's evolution was favorable, and she was discharged with recommendations to continue the treatment with spironolactone treatment for 30 days followed by cardiology reassessment and vaccination according to the national schedule, including influenza vaccination for the 2024/2025 season. Discussions : Influenza is a common respiratory infection with the potential for severe complications. Acute respiratory infection with influenza A virus complicated by myocarditis currently does not affect cardiac function but requires cardiac monitoring. Early recognition, prompt diagnosis, and appropriate management are essential to prevent complications and reduce morbidity and mortality associated with influenza infection. Vaccination and other preventive measures play a critical role in mitigating the impact of influenza and its complications on public health. Conclusions: This case underscores the need for heightened awareness among healthcare providers regarding the diverse clinical presentations of influenza-related complications, facilitating early diagnosis and targeted interventions to mitigate morbidity and mortality associated with myocarditis in the pediatrics population.

The purpose of this paper is to present the results of the authors' research focused to obtain an improved behavior of a forklift truck by modifying its electrical control diagram. Detailed knowledge about every part of the electrical installation and identification of the typical frequent failures can lead to reduced repairing time intervals. The authors propose to use a protection contactor equipped with a diode in direct mode connection placed in its supplying circuit. Thus, in reverse supply, the contactor practically does not engage and therefore the circuits are protected. The power circuit of the protection contactor includes all the supply voltage modules except for the traction, steering and hydraulic modules which are supplied by the main contactor controlled by the central unit only when the latter is 48V supplied. So, whenever the voltage supply is accidentally reversed, the protection contactor is open, providing full protection to all the modules. [ABSTRACT FROM AUTHOR]

In the field of optical fibers, which is today continuously growing, the research efforts are directed in two main directions: the first is finding materials with superior characteristics and the second - closely related - the development of performant technologies and plants, capable of achieving the desired quality at more accesible costs. Advances in this area are determined by the construction and improvement of tunable laser diodes, optical fibers with low dispersion losses, optical integrated circuits for high speed connection technologies and external modulators; all of these allow the transmission over distances of tens of kilometers of information flows over 11 Gbit/sec using bi-directional on two optical fibers or a single fiber using the multiplexing technique by wavelength.

Introduction: Stroke is a rare pathology in pediatrics, which due to the progress in imagistic techniques is more and more frequently diagnosed. It can be either ischemic or hemorrhagic, the ischemic one being more frequent in child, with multiple causes and different risk factors. The early diagnosis is essential for the proper treatment. The aim is to present a rare pathology in infant that requires a prompt, multidisciplinary approach for the diagnosis and emergency treatment. Material and method: We present the case of a 7-month-old male infant admitted in our clinic due to a sudden right hemiparesis and central facial one. Results: The 7-month-old patient, without family or personal pathological history, presented the onset of the disease approximately 27 hours before the admission with clonic manifestations of the right superior limb and oral commissure, followed by the development of a right hemiparesis and a central facial one. The imagistic investigations pointed out a cortical ischemic injury, affecting 2 thirds of the left cerebral hemisphere, with the lack of opacification in the left medium cerebral artery, establishing the diagnosis of ischemic stroke. We identified the following risk factors: arteriovenous malformation (hypoplasia of the left internal carotid artery), anti-phospholipidic syndrome, thrombophilia and dyslipidemia. Under neurologic supportive therapy, anticoagulant, vasodilator, depletive and anticonvulsant treatment, the patient's evolution was favorable, starting the physical recovery after 3 weeks from the onset. Conclusions: The diagnosis of stroke must be considered at any age, and the identification of the risk factors is essential for these patients' management that require multidisciplinary approach.

Introduction: According to NASPGHAN, intestinal pseudo-obstruction is a severe condition characterized by episodes and signs of intestinal obstruction, including radiological signs of intestinal dilatation, in the absence of fixed lesions that obstructs the intestinal lumen. Purpose of this paper is to present a case of a rare and heterogeneous clinical syndrome with a relapsing and remitting pattern that appears idioaptic (as a consequence of visceral myopathy or neuropathy) or in non-intestinal disorders. Material and method: We present the case of a 12-year-old female child known for genetic syndrome, cachexia, sequelae encephalopathy, neuropsychomotor retard, cheilognatopalatoschizis resolved surgically, which in the last 2 years experienced abdominal meteorism episodes with severe constipation. She was admitted in our clinic with acute abdominal meteorism, abdominal pain, constipation. Results: Abdominal radiography detects generalized marked colon gas and abdominal CT evokes aeroenteria, the ascending colon with a minimal content of faecal matter with thin walls, 220/110 mm in diameter, with compressive effect on parenchymal organs. In spite of medical treatment and therapeutic maneuvers, the abdomen continues to distend, there is intense abdominal pain, absence of faecal matter, with ineffective defecation effort, so it intervenes surgically by practicing colostomy, with no evidence of an intraoperative mechanical obstacle, death occurring within 48 hours of the intervention. Conclusions: A child with neurological conditions, known for accentuated meteorism episodes and bowel movements disorders, presents severe form of intestinal motility disorder, manifested as a fatal pseudo-occlusive intestinal syndrome.

Introduction. Approximately 12 million children die every year in developing countries and one third of these deaths are caused by pneumonias. The assessment of radiological changes in dynamics owns a major role in establishing the diagnosis of staphylococcal pneumonia. The aim of this paper was to underline the diagnostic and treatment difficulties in a child with staphylococcal pneumonia. Case report. We present the case of a 2 years and 6-month-old male patient admitted in our clinic for hyperpyrexia, productive cough, rhinorrhea and anorexia. The clinical exam at admission pointed out influenced general status, pale ailing face, pallor, fever, productive cough, rhinorrhea, diminished breath sound on the right side, oxygen saturation 97% and anorexia, while de blood tests revealed severe leukocytosis with neutrophilia, anemia, and severely increased inflammatory biomarkers. The chest X-ray showed an opacity within the right inferior lobe. The blood culture was negative. We initiated symptomatic and antibiotic treatment (Ceftriaxone), but due to the unfavorable evolution, the control chest X-ray showed a consolidation area within the right inferior lobe and secluded basal pleural effusion as well as on the right lateral side. We performed also a chest computed tomography (CT), noticing a pneumonic process within two segments of the inferior right lobe, several grouped pneumatocele below the pleura, associating within both lungs areas of lobular hyperinflation. Thus, we raised the suspicion of staphylococcal pneumonia, and we initiated Vancomycin by vein, with favorable evolution. Conclusions. Staphylococcal pneumonia is a well-defined and described pathology in the literature, but still remains a contemporary pathology imposing multiple difficulties related to the diagnosis and management in pediatric patients.

One of the major causes leading to increased antibiotic resistance is excess antimicrobial consumption. We have analysed the correlation between antibiotic use and frequency of carbapenem-resistant Pseudomonas aeruginosa (CRPA) strains in the general intensive care unit of a university hospital Antibiotic use was expressed as number DDD (daily defined doses)/100 occupied hospital bed-days (BD). CRPA incidence rates were determined by number of unique isolates reported to 100,000 BD. The average use of antibiotics between January and August 2008 was 174 DDD/100 BD. The first four most frequently prescribed antibiotics were as follows: first and second generation cephalosporins (47 DDD/100 BD), carbapenemns (29 DDD/100 BD), fluoroquinolones (26 DDD/100 BD) and glycopeptids (20 DDD/100 BD). Average monthly incidence rate of CRPA was 546/100,000 BD (319-773/100,000 BD. CI 95%). There was a correlation between CRPA incidence rate and carbapenem plus fluoroquinolone use (Pearson coefficient of correlation r = 0.7, p < 0.05). Our data showed that the evolution of CRPA incidence rates was related to carbapenem and fluoroquinolone use.
