The use of 3D laparoscopic partial nephrectomy has emerged as a cornerstone in the surgical arsenal for addressing renal tumors, particularly in managing challenging cases characterized by deeply seated tumors embedded within the renal parenchyma. In these intricate scenarios, the utilization of intraoperative ultrasound (IOUS) acquires paramount importance, serving as an indispensable tool for guiding and meticulously monitoring the surgical process in real time. To further explore the efficacy of IOUS-guided techniques, we conducted a retrospective study comparing outcomes in patients who underwent partial nephrectomy with IOUS guidance (n = 60) between 2020 and 2022 with a cohort from 2018 to 2019 without IOUS guidance (n = 25). Our comprehensive analysis encompassed various post-operative parameters, including the duration until food resumption, analgesia requirements, and length of the hospital stay. While these parameters exhibited comparable outcomes between the two groups, notable distinctions emerged in the intraoperative metrics. The IOUS-guided cohort demonstrated significantly reduced blood loss, a shorter median operative duration, and diminished ischemia time (p = 0.001). These compelling findings underscore the undeniable benefits of IOUS-guided techniques in not only facilitating the attainment of negative surgical margins but also in enhancing procedural safety and precision, thereby contributing to improved patient outcomes in the management of renal tumors.

The cutaneous manifestations of coronavirus disease 2019 (COVID-19) have been covered insufficiently in the literature. Thirty-nine patients admitted to the study hospital with confirmed COVID-19 who experienced various skin manifestations during hospitalization or in the convalescence period, were analysed retrospectively. Thirty-nine patients with COVID-19, admitted to the study hospital between 23 March and 12 September 2020, had intra-infectious rash or lesions of cutaneous vasculitis during convalescence. The most common cutaneous manifestations of COVID-19 were erythematous and erythematous papular rash. Twenty-seven of the 39 patients had anosmia (69.2%), 26 patients had ageusia (66.7%), 34 patients had pneumonia (87.2%) and 24 patients had intra-infectious enterocolitis (61.5%). Skin biopsies were rarely performed in these patients. This article reports the results of biopsies performed in two patients, showing histopathological and immunohistochemical changes in erythematous rash and erythema multiforme-like lesions. Both skin biopsies revealed early fibrous remodelling of the dermis, suggesting similarity with changes that occur in the lungs and other tissues in patients with COVID-19. Correlations between skin lesions and anosmia, ageusia and enteritis in patients with COVID-19 do not seem to be accidental, but are associated with a similar response to ACE2 receptor expression in these tissues.

Myocardial injury in patients with SARS-CoV-2 infection may be attributed to the presence of the virus at the cellular level, however, it may also be secondary to other diseases, playing an essential role in the evolution of the disease. We evaluated 16 patients who died because of SARS-CoV-2 infection and analyzed the group from both clinical and pathological points of view. All autopsies were conducted in the Sibiu County morgue, taking into consideration all the national protocols for COVID-19 patients. Of the 16 autopsies we performed, two were complete, including an extensive examination of the cranial cavity. In our study, the cardiac injury was primarily cumulative. Chronic cardiac injuries included fatty infiltration of the myocardium in five cases, fibrosis in 11 cases, and coronary atherosclerosis in two cases. Among the cases with evidence of acute cardiovascular injuries, inflammatory lymphocytic infiltrate was observed in nine cases, subepicardial or visceral pericardial neutrophil-rich vascular congestion in five cases, and venous thrombosis in three cases. Acute ischemia or myocytic distress was identified by vacuolar degeneration in four cases; areas of undulated and/or fragmented myocardial fibers, with eosinophilia and nuclear pyknosis with or without enucleation of the myocytes in nine cases; and in one case, we observed a large area of myocardial necrosis. Immunohistochemical criteria confirmed the presence of the SARS-CoV-2 antigen at the level of the myocardium in only two cases. Comorbidities existing prior to SARS-CoV-2 infection associated with systemic and local inflammatory, thrombotic, hypoxic, or immunological phenomena influence the development of cardiac lesions, leading to death.

Background: Malignant tumors represent a significant pathology with a profound global impact on the medical system. The fight against cancer represents a significant challenge, with multidisciplinary teams identifying numerous areas requiring improvement to enhance the prognosis. Facilitating the patient’s journey from diagnosis to treatment represents one such area of concern. One area of research interest is the use of various biomarkers to accurately predict the outcome of these patients. A substantial body of research has been conducted over the years examining the relationship between C-reactive protein (CRP) and malignant tumors. The existing literature suggests that combining imaging diagnostic modalities with biomarkers, such as CRP, may enhance diagnostic accuracy. Methods: A systematic review was conducted on the PubMed and Web of Science platforms with the objective of documenting the interrelationship between CRP value and tumor grading for malignant tumors. After the application of the exclusion and inclusion criteria, 17 studies were identified, published between 2002 and 2024, comprising a total of 9727 patients. Results: These studies indicate this interrelationship for soft tissue sarcomas and for renal, colorectal, esophageal, pancreatic, brain, bronchopulmonary, ovarian, and mesenchymal tumors. Conclusions: Elevated CRP levels are correlated with higher grading, thereby underscoring the potential utility of this biomarker in clinical prognostication.

Background/Objectives: Colorectal cancer (CRC) is a major global health concern with rising incidence and mortality. MicroRNAs (miRNAs) play key roles in tumor progression, invasion, and metastasis. This study aimed to analyze the expression of miR-101-3p, miR-106a-5p, and miR-326 in CRC patients and assess their association with tumor grading and tissue invasion. Methods: A total of 40 CRC patients were included in the study. miRNA expression levels were measured using quantitative reverse transcription PCR (qRT-PCR). Statistical analyses, including regression models, were performed to evaluate correlations between miRNA expression, tumor grade, and invasion patterns. Results: MiR-101-3p was significantly downregulated in advanced tumors, while miR-106a-5p expression peaked in Grade 2 CRC. MiR-326 expression was associated with organ metastasis. Regression models confirmed complex interaction patterns among these miRNAs, suggesting their potential role in CRC progression. Conclusions: These findings indicate that miR-101-3p, miR-106a-5p, and miR-326 are associated with CRC severity and invasion. Their expression patterns suggest potential utility as biomarkers for early detection and targeted therapies. Further studies with larger cohorts are needed to validate these results and explore their clinical applications.
