Introduction: The aim of our study was to investigate renal lithiasis in the urology department of UHC Gabriel Touré. Materials and Methods: This was a prospective and descriptive study from 1 July 2016 to 30 June 2017 (12 months). All patients were included in our study in whom at least one renal lithiasis larger than 4 mm was diagnosed on imaging and whose management was carried out in the urology department of UHC Gabriel Touré. Results: During the study period, we recorded 23 cases of renal lithiasis out of 49 cases of urinary lithiasis, i.e. 47% of cases. The age group 31 to 40 years was the most represented with 26.1% with an average age of 36 years and extremes ranging from 6 to 62 years. The sex ratio was 1.6 in favour of men. Shopkeepers were the most represented group, accounting for 34.8% of cases. The most common risk factors were meat (87%), milk (65.2%) and fish (52.2%). The main reason for consultation was lumbar pain, with 18 cases (78.3%). Caliciolithiasis of the kidney was the most common, accounting for 65.2% of cases. The right kidney was more affected with 69.6% of cases. Nephrolithotomy was performed in 65.2% of patients, pyelolithotomy in 30.5% and nephrectomy in 4.3% (1 case). Conclusion: Urinary lithiasis is a pathology whose frequency is constantly increasing in both industrialised and developing countries due to changes in socio-economic levels. It affects young adults, especially males.
Exceptional Location of a Pleomorphic Leiosarcoma: Clinical Case
Authors: Kessab Amine , Traibi Akram , Boudhas Adil , Atoini Fouad , Sinaa Mohamed
Published: July 2024

Pleomorphic leiomyosarcoma is a rare entity that is part of the pleomorphic sarcomas with a complex genome with a high metastatic capacity and a usually poor prognosis. The most common location remains the lower extremities but other sites have been reported in the literature, particularly in the chest wall. Leiomyosarcoma (LMS) is an exceptionally rare tumor in the chest wall. Classical LMS may exhibit focal areas of pleomorphic cells; however, the coexistence of a large pleomorphic component allows the tumor to be designated as pleomorphic leiomyosarcoma (PLMS). The first cases of pleomorphic leiomyosarcoma were reported in the literature by Brooks in 1985. The pleomorphic component of these tumors is often heterologous with either cartilaginous differentiation; bony or rhabdomyosarcomatous. Since pleomorphic myogenic sarcomas, including high-grade leiomyosarcomas and rhabdomyosarcomas, have a poorer prognosis hence the importance of an accurate and valid histological diagnosis. The thoracic location of a leiomyosarcoma remains exceptional or even extremely rare and management requires multidisciplinary consultation involving the surgeon; the oncologist and the radiotherapist with additional molecular study to properly detect genetic anomalies in order to consider possible targeted therapy.

Published: July 2024

Non-traumatic hip pain in adolescents presents a significant diagnostic challenge. We report the case of a 19-year-old female patient treated for idiopathic juvenile osteoporosis with zoledronic acid, presenting with chronic inflammatory right hip pain that responded well to NSAIDs, associated with back and buttock pain. The inflammatory markers, including CRP and ESR, were negative. The pelvic radiography was normal, though thoracolumbar spine radiography revealed scoliosis. Consequently, MRI of the sacroiliac joints was performed to search for sacroiliitis but revealed a 5 mm nidus with reactive sclerosis, suggestive of an osteoid osteoma. The natural progression of the patient's pain showed spontaneous regression within one year.

Myasthenia gravis (MG) is an autoimmune disorder affecting the neuromuscular junction caused by a B-cell-mediated, T-cell-dependent immunologic attack at the end plate of the postsynaptic membrane. Attack on muscle acetylcholine receptors (AChR) of the postsynaptic membrane due to the AChR, muscle-specific tyrosine kinase, or lipoprotein receptor-related peptide 4 antibodies lead to symptoms of painless, fluctuating weakness of muscle groups and often begins with ocular signs and symptoms. Coronavirus disease 2019 (COVID-19) is an acute respiratory disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus closely related to SARS-CoV. Serious neurologic complications are infrequent and diverse with reported cases of stroke, encephalitis/meningitis, Guillain-Barré syndrome, acute disseminated encephalomyelitis, ataxia, and unspecified limb weakness. MG is a rarely reported sequela of COVID-19 infection. To date, there are 15 reported cases of post-COVID-19 MG. In this article, we present a case of post-COVID-19 MG and a concise review of other reported cases. An 83-year-old Caucasian male with a medical history of atrial fibrillation status post-ablation and non-ischemic cardiomyopathy was initially admitted for COVID-19 pneumonia. He was treated with remdesivir, convalescent plasma, and supplemental oxygen therapy but did not require invasive mechanical intubation. One month after discharge, he started experiencing fatigue with muscle weakness and progressive dyspnea. He progressed to develop dysphonia, especially at the end of the day. After extensive workup, he was diagnosed with MG with a positive antibody against the AChR. The chronological events of developing slowly worsening muscular weakness after recovering from COVID-19 infection and positive AChR antibody led to the diagnosis of post-COVID-19 new-onset MG. Post-COVID-19 fatigue, long-term use of steroids, and intensive care unit-related physical deconditioning ....

Objective.
To study virulence genes in E. faecium and E. faecalis isolated from the blood cultures of patients with hematological diseases.

Materials and Methods.
Virulence genes were studied in E. faecium and E. faecalis strains isolated from blood culture from hematological patients in four Russian hospitals (2002–2020). Susceptibility to vancomycin was determined by broth microdilution method (CLSI, 2022). Virulence genes (esp, hyl, asa1, cylA and gelE) in E. faecium and E. faecalis as well as vancomycin resistance genes (vanA, vanB and vanD) in Enterococcus spp. were detected by multiplex PCR.

Results.
A total of 551 Enterococcus spp. strains were studied, of them 440 (79.9%) were E. faecium and 111 (20.1%) E. faecalis. Resistance to vancomycin was detected in 86 (19.5%) E. faecium, of them 62 (72.1%) carried vanA and 24 (27.9%) vanB genes. One (1.1%) of 111 E. faecalis was vancomycinintermediate (MIC 16 μg/ml) with vanD gene. Virulence genes were detected in 86.2% of Enterococcus spp., significantly more often among E. faecalis (95.5%) compared to E. faecium (83.9%, p = 0.003). The predominant genes in E. faecium were esp (70.2%) and hyl (52.1%), the detection of the asa1, cylA and gelE genes was minimal. Other genes dominated in E. faecalis: gelE (66.7%), asa1 (65.8%), cylA (36.9%). Statistically significant differences between E. faecium and E. faecalis were determined for all studied virulence genes (p < 0.0001). A combination of three or more virulence genes was detected significantly more often among E. faecalis in comparison with E. faecium (45% vs. 2.5%, p < 0.0001), whereas the presence of one gene or their absence prevailed in E. faecium (40.2% vs. 17.1%, p < 0.0001; 16.1% vs. 4.5%, p = 0.003, respectively). When comparing the two study periods (2002–2010 and 2011–2020), E. faecalis showed a significant increase in the proportion of strains with a combination of three or more virulence genes from 33.3% to 55% (p = 0.03), in E. faecium – with one virulence gene (from 31.7% to 46.3%, p = 0.002) and no genes (from 6.6% to 23%, p < 0.0001).

Conclusions.
Differences in the frequency of detection of virulence genes and their spectrum have been identified between E. faecium and E. faecalis strains. Virulence genes are significantly more often detected in E. faecalis with a predominance of combinations of three or more genes.

Towards a Theory of Collective Care as Pedagogy in Higher Education
Authors: Legassic Cory
Published: July 2024

This piece offers a conceptual framework for collective care as pedagogy in higher education, and a proposition of how to theorize its orientations within anticolonial and feminist work on affect in education. First, I spotlight work that helps to define collective care. Next, I call on the concept of affective individualism as a way to describe what is: the taken-for-granted affective governmentality (Zembylas, 2021) that shapes how we often come together in our classrooms. Finally, I ground collective care as pedagogy as the building of affective solidarity, an affective conceptual framework for what could be, grounded in the feminist work of Clare Hemmings (2012).

this paper considers the main stages of the development of complex-functional digital IP-blocks as part of ultra-large integrated circuits (ULSI) and systems on chip (SoC). Formulated the main advantages and disadvantages of the integrated circuits (IC) design concept using standard cells and IP-blocks are outlined, and the main objectives of the application of this concept. The place of IP-blocks in the SoC design route is determined, on basis of which the hierarchy of priority of some stages of the design of custom IP-blocks is highlighted. Some aspects of standardization in design at the model level are considered in order to avoid conflict situations when placing and connecting cells. The composition of the final topological, circuit design and description files is analyzed, which is necessary and sufficient for the delivery of the developed block to the customer, and its subsequent application in the design route. The methods of protecting commercial information when transferring topology files to enterprises producing IC crystals are given. Software capabilities (verification, synthesis of digital automata, topology design using automation tools) in the design of IP-blocks were described within the framework of the functionality of software tools provided by Cadence, Mentor Graphics, Synopsis. The relevant actions of the IP-block customer after receiving the necessary modeling, topology, description and documentation files are briefly touched
