Background: The impact of COVID-19 and long-term COVID-19 on gastrointestinal neoplasms remains underexplored. The current review investigates the potential link between these conditions and the role of gut microbiota in mediating oncogenic processes. Dysbiosis, characterized by alterations in gut microbial composition, may exacerbate inflammation and immune dysregulation, contributing to cancer development.Methods: A comprehensive literature review was conducted using databases including PubMed, Scopus, Embase, SciELO, and Web of Science. Inclusion criteria encompassed studies published between 2020 and 2024 that explored the intersection of COVID-19, long-term COVID-19, and gastrointestinal cancers. The articles were critically appraised for quality and relevance, and data were synthesized to elucidate common mechanisms and outcomes.Results: The review identifies several mechanisms by which gut microbiota may influence cancer risk in COVID-19 patients. Persistent inflammation, oxidative stress, and immune dysfunction observed in Long COVID were associated with dysbiosis. Specific microbial metabolites, such as secondary bile and short-chain fatty acids, were implicated in promoting tumorigenesis. Comparative analysis of studies suggests that SARS-CoV-2-induced dysbiosis may heighten susceptibility to gastrointestinal cancers, particularly in patients with prolonged post-infection symptoms.Conclusion: The findings underscore the need for further research to clarify the role of gut microbiota in cancer development among COVID-19 patients. These mechanisms could inform preventative strategies and therapeutic interventions, particularly for those experiencing COVID. The review highlights gaps in current knowledge and advocates for longitudinal studies to assess the long-term effects of COVID-19 on gastrointestinal health.

The overall incidence of meningitis in infants 0-90 days is low; however, it remains a serious cause of morbidity and mortality among affected patients. It is standard of care to perform lumbar punctures as part of the work-up of fever in the first four weeks of life and sick-looking babies up to the age of 90 days. This particular procedure is often refused by parents, and physicians are left to predict the possibility of meningitis based on blood culture results.The aim of this study is to determine whether it would be safe to rule out meningitis based on a negative blood culture in this age group.

Zoon’s vulvitis or plasma cell vulvitis (PCV) is a rare, benign inflammatory condition of the vulvar mucosa [1]. PCV can present with an asymptomatic lesion, or can cause discomfort, dyspareunia and pruritus [2]. In this way, PCV can mimic other lesions of the vulval mucosa, such as lichen planus.

The Anterolateral Ligament (ALL) [1,2] is a ligamentous structure of the knee whose definition as a ligament has been disputed in the past, however in the last decade more and more anatomical studies have concluded that its definition as a separate ligament is the most accurate. In this case report we present our findings from the dissection of a formalinized cadaver which we find are consistent with the anatomical characteristics of the anterolateral ligament and with that we aim to further its morphological definition.

Toxic epidermal necrolysis -the most serious variant of Steven Johnson Syndrome -arises as the result of cell-mediated cytotoxic reaction against keratinocytes. Most common inciting factors include drugs, and infections. On the other hand, Hemophagocytic lymphohistiocytosis (HLH), is a syndrome characterized by enormous immune response in the absence of down-regulation of activated immune cells resulting in cytokine storm causing severe tissue damage. Up to date, several cases of concomitance of Toxic Epidermal Necrolysis (TEN) and Hemophagocytic Lympohystiocytosis (HLH) in pediatric patients have been reported. Both situations can be fatal and pediatricians should be aware that these two clinical entities are not mutually exclusive, to the contrary they may coexist. We herein describe a case of Toxic Epidermal Necrolysis, complicated with Hemophagocytic Lymphohistiocytosis with Central Nervous System involvement due to EBV infection.

A 25-year-old man presented with fever and rash which progressed to extensive vesicular eruptions all over the body by the 4th day (Figure 1A).

Introduction: In the latest WHO classification of central nervous system tumors, Mitotic Index (MI) counted on Phosphohistone-H3 stained slides (pHH3-MI) has been suggested as a valid proliferative marker in various tumors including in the evaluation of meningioma grading.We aim to report our own experience in assessing the efficiency of the anti-pHH3 antibody as a grading tool for meningiomas.Methods: A retrospective study was conducted on a series of 40 meningiomas diagnosed from March 2020 to April 2021 at the Pathology Department of the Military Hospital of Tunis. We attempted immunohistochemistry and compared MI assessed on both pHH3 and HE-stained slides.Results: According to the HE-MI and pHH3-MI, the 40 cases of meningiomas were respectively divided into 35 versus 29 grade 1 cases, four versus eight grade 2 cases, and one versus three grade 3 cases. A highly significant correlation was found between pHH3-MI and HE-MI (p < 0.001). A significantly higher sensitivity in the pHH3 counting method was reported in our study. Discussion: we found, in accordance with the literature, that pHH3-MI is more reliable and accurate in mitotic counting, therefore exhibiting a high sensitivity in tumor grading, reported by an upgrade within 22,5% of the cases.Conclusion: PHH3-MI count facilitated a rapid reliable grading of meningiomas. However, molecular characteristics that could have a potentially significant impact on tumor progression should be the subject of further research.

Diseases - diabetes mellitus (especially type 1) and autoimmune diseases are incurable diseases. In type 1 diabetes, the beta cells of the tail of the pancreas die. It is in the beta cells of the tail of the pancreas that insulin is located, a hormone that maintains normal blood sugar levels in patients with type 1 diabetes. Until now, no methods have been known to restore dead pancreatic beta cells. Methods for restoring the lymphoid system in patients with autoimmune diseases were not known. With these diseases, the normal properties of the lymphoid system are lost. This review aims to present materials on the effective treatment (cure) of these diseases. For the treatment, the resonance therapy method was used, which has been known for at least 25 years and which has been modified in our work since 2016. The essence of our modification was that the author began to use 1. Not only low (previously known) but also high potencies of resonant drugs. 2. We have created a direction in resonance therapy, which is called “resonance of creation.” So far, only the direction is known as “resonance of destruction” is known, with the help of which oncological tissues, infectious processes, cysts, stones, etc. are treated - destroyed. With the help of the resonance of creation, various biological structures that have undergone degeneration and death are restored - the myelin sheath of the nerves in multiple sclerosis, nerve cells in Parkinson’s disease and Alzheimer’s disease, etc. With the help of the resonance of creation, the beta cells of the tail of the pancreas are restored in type 1 diabetes and restoration of the lymphoid system in autoimmune diseases. So, in patients with autoimmune diseases, organ preparations were tested: “lymph nodes”, “lymphocytes”. It turned out that in all patients with various autoimmune diseases, lymph nodes, and lymphocytes were tested as being in a degenerative state. There was not a single patient whose lymph nodes and lymphocytes were tested as normal. The task was to normalize the functional state of the lymph nodes and lymphocytes in our patients and thereby take an important step towards curing their autoimmune disease. To this end, it was necessary to increase the potency of the lymph nodes and lymphocytes in the same way as we did it in relation to the beta cells of the pancreas in patients with diabetes mellitus, in relation to the substantia nigra of the midbrain in patients with Parkinson’s disease and in relation to the myelin sheath. Nerves in multiple sclerosis. After testing organ preparations: “lymph nodes”, and “lymphocytes” in patients with autoimmune diseases, the potency was selected, which led to the fact that lymph nodes and lymphocytes were no longer tested as degenerated formations. It was this potency of lymph nodes and lymphocytes that was the basis for the treatment of patients. Thus, as a result of the treatment of diabetes mellitus (especially type 1) and autoimmune diseases by resonance therapy, these diseases become curable.

Introduction: Alternatively using gradient lower-body negative pressure (LBNP) and ergometer exercise (LBNP + ergo) under a flight schedule framework was explored to detect its orthostatic capacity maintenance effects in female subjects after 15 days of -6° head-down bed rest (HDBR). Methods: Twenty-two female university students were divided into a control group (n = 8), an LBNP group (n = 7), and an LBNP + ergo group (n = 7). Ergometer exercise consisted of an interval exercise protocol with 2 min intervals alternating between 41% and 70% VO2max. Gradient LBNP was decompressed in 10 mm Hg intervals to -40 mmHg every 5 min. intermittent ergometer exercise and LBNP were alternatively performed. Tilt test was performed 2 days before HDBR (R-2), on the day of HDBR termination (R+1), and 5 days after HDBR (R+5). Results: Fifty percent of the participants (11/22) did not pass the tilt test on R+1. The orthostatic tolerance time decreased from 20 to 16.1 ± 2.1 min in the control group, to 10.0 ± 2.7 min in the LBNP group (p = 0.01) and to 16.3 ± 2.0 min in the LBNP + ergo group. The HRs and BPs were at similar level among three groups during tilt test on different test days. Compared with the control group, the LBNP + ergo group had higher SV and CO percentage changes at R+1(p < 0.023) and R+5 (p < 0.00001) during the tilt test. Conclusion: LBNP combined with ergometer exercises fails to prevent orthostatic intolerance but it induced some positive hemodynamic changes during tilt test after 15 days HDBR.

The introduction of a new class of drugs known as direct acting antiviral (DAA) agents represents a revolution in the treatment of hepatitis C virus (HCV) in the general population, as these regimens are associated with higher sustained virological response (SVR) rates and fewer side effects. However, for patients with advanced chronic kidney disease suffering from HVC infection, treatment options including DAA remain limited. The aim of this study is to report our experience on Sofosbuvir (SOF) based regimen in the treatment of HCV in hemodialysis patients.In this observational study, we included all patients with chronic HCV infection on hemodialysis who were treated with SOF in our Hospital between April 2016 and March 2018. All patients were treated with a combination of 400 mg of SOF three times a week after hemodialysis and of 60 mg of Daclatasvir daily for a total of 12 to 24 weeks.A total of 20 hemodialysis patients were included in this study. 12 were females and the mean age was 52.1 ± 15.5 years. 11 patients were infected with HCV genotypes 1b. All patients achieved SVR. Clinical and biological tolerance was very good for all patients and none of them had to discontinue treatment because of side effects or developed hepatobiliary and cardiac toxicity. Two patients reported fatigue and another patient reported headaches. However, these symptoms were spontaneously resolved after the end of the treatment.In Morocco, despite the absence of new DAA combination treatment regimens which are not renally eliminated, our study concludes that SOF based treatment without Ribavirin or Peginterferon was effective and safe with minimal side effects. However, larger studies are still needed in order to validate these results.
