Endovascular Coil Embolization of a Large Ruptured Splenic Artery Aneurysm: A Case Report.

This case report aims to elucidate the current practices and efficacy of endovascular repair in managing splenic artery aneurysms (SAAs), particularly focusing on a case of a large, partially ruptured SAA. A 66-year-old female presented with severe abdominal pain and was later diagnosed with a 53mm saccular, degenerative SAA showing signs of partial rupture. The patient underwent successful endovascular repair using a combination of interlocking detachable coils and fibered coils. Despite the initial success, a follow-up CT angiogram revealed residual issues, necessitating additional embolization. The patient recovered well, with subsequent follow-ups indicating complete aneurysm closure and no complications. The successful management of this case aligns with current trends in SAA treatment, emphasizing the shift towards endovascular repair methods. This approach, highlighted in the literature, offers a minimally invasive alternative to open surgery, with lower morbidity and mortality rates. This case underscores the importance of individualized treatment planning and vigilant follow-up, particularly in light of the potential need for secondary interventions. This report contributes to the growing body of evidence supporting endovascular repair as a safe and effective treatment for SAAs, advocating for continued research into long-term outcomes and the development of advanced endovascular technologies.

A Successful Endovascular Treatment of Massive Hematuria Caused by Aorto-Ureteric Fistula: A Report of a Rare Case.

Fistula formation between the urinary tract and the arterial system is very rare, and usually involves the ureter and the adjacent iliac vessels. Communication of the ureter with the aorta has been described a few times worldwide, and most of them had a fatal outcome. In our case, a 79-year-old man had a history of total cystectomy for malignancy and diversion of both ureters to a single site in the right hypogastrium with the left one crossing over the aorta. He was admitted elsewhere several times for intermittent hematuria, and four months ago the diagnosis of communication of the left ureter with a mycotic aortic pseudoaneurysm was made. He was then referred to an interventional radiologist who sealed the communication. He was admitted to our hospital four months later in a state of hypovolemic shock and massive hematuria. In lack of information, it seemed to us that he had been treated with endovascular aneurysm repair (EVAR) for uretero-aortic communication, and was experiencing a regression because of endoleak formation. We attempted to treat him as type I endoleak with a proximal extension, and upon failure, with distal extensions, but finally we had to 'build' the entire previous graft from the inside to achieve hemodynamic stability. Our patient remained stable, without endoleak on the post-intervention computed tomography angiography (CTA). Post-operatively, we discovered that the initial operation was the formation of a bifurcated graft with multiple bare stents and coil embolization through them. This was done in an attempt to avoid material infection by the mycotic aneurysm. This is an example of a case where 'things got rough' in a lack of information on patients' medical records. Maybe the time has come to adopt the concept of implanting microchips into humans which would enable doctors to access their medical records. This will only serve as a tool for the benefit of the suffering patients, especially when we are dealing with life-threatening situations with no time to be lost.

The Neutrophil-to-Lymphocyte Ratio as a Biomarker in Cutaneous Oncology: A Systematic Review of Evidence beyond Malignant Melanoma.

With the ongoing progress of basic research along with the introduction of new pharmaceutical options spanning almost all therapeutic areas, the need for biomarkers that will be implemented into the personalized medical approach is higher than ever. Their use can be incorporated into clinical practice and can be applied to the classification of disorders and the evaluation of disease severity but also to the monitoring of the progress of therapeutic/pharmaceutical interventions. This systematic review collects the findings of hematologic biomarkers in various cutaneous malignancies, excluding malignant melanoma, to support their potential use in the prognosis but also in the assessment of therapeutic strategies for the specific category of skin disorders.

Extracellular Vesicles as Novel Diagnostic and Therapeutic Agents for Non-Melanoma Skin Cancer: A Systematic Review.

Standard non-melanoma skin cancer (NMSC) treatment involves surgery, recently combined with chemotherapy or immunotherapy in cases of advanced tumors. EVs, including exosomes, are integral to carcinogenesis, and are found in NMSC releasing mediators impacting tumor progression. Nevertheless, the precise intercellular signaling role of NMSC-derived EVs remains unclear. This review aims to elucidate their potential role in NMSC diagnosis and treatment. This systematic review encompassed literature searches in electronic databases from inception to September 2023, based on certain inclusion and exclusion criteria, addressing NMSC-derived EVs, their molecular cargo, and their implications in the diagnosis, prognosis, and treatment of NMSC. Key components were identified. Extracellular vesicle (EV) proteins and RNA have emerged as diagnostic biomarkers in EV-based liquid biopsy. Circular RNA CYP24A1, known for its molecular stability, holds promise as a diagnostic biomarker. Long noncoding RNAs (lincRNA-PICSAR) and Desmoglein 2 (DSg2) are linked to drug resistance, serving as prognostic biomarkers. EV mediators are being actively investigated for their potential role as drug delivery agents. In conclusion, this systematic review showed that NMSC-derived EVs display promise as therapeutic targets and diagnostic biomarkers. Further research is imperative to fully comprehend EV mechanisms and explore their potential in cancer diagnosis and treatment.

Visceral Artery Revascularization With the "Roof-Top" Approach: An Alternative Technique With Great Exposure of the Suprarenal Aorta.

Due to the extensive collateral arterial network, symptomatic chronic mesenteric ischemia is a relatively uncommon condition and is associated with severe atherosclerotic disease of all major visceral arteries. Open surgical repair has been commonly used to restore blood supply to the visceral arteries, and the "roof-top" approach has been advocated as an alternative technique to traditional midline incision, mainly because of the great exposure of the suprarenal aorta that it offers. Roof-top approach, in other words, bilateral subcostal incision, is a totally abdominal approach to the suprarenal aorta, and as the title says, it is like a roof-top on the abdominal wall. We present a case of a female patient with intestinal angina that was deemed unsuitable for endovascular repair (ER) and was treated with open surgical repair utilizing the "roof-top" approach.

Intraoperative Flow Cytometry for the Rapid Diagnosis and Validation of Surgical Clearance of Non-Melanoma Skin Cancer: A Prospective Clinical Feasibility Study.

Non-melanoma skin cancer (NMSC) is the most prevalent cancer in humans, with a high global incidence. We present a prospective clinical feasibility study on the use of intraoperative flow cytometry (iFC) for the instant diagnosis of NMSC and its complete surgical clearance. Flow cytometry, a laser-based technique, quantifies cell features, which has applications in cancer research. This study aim is to explore the potential applicability of iFC in detecting and characterizing NMSC and its surgical margins. In total, 30 patients who underwent diagnosis for NMSC were recruited. The method demonstrated high sensitivity (95.2%) and specificity (87.1%), with an accuracy of 91.1%, as confirmed with a receiver operating characteristic curve analysis. The results also indicated that most tumors were diploid, with two cases being hypoploid. The average G0/G1 fractions for normal and tumor tissue samples were 96.03 ± 0.30% and 88.03 ± 1.29%, respectively, with the tumor index escalating from 3.89 ± 0.30% to 11.95 ± 1.29% in cancerous cells. These findings underscore iFC's capability for precise intraoperative NMSC characterization and margin evaluation, promising enhanced complete tumor excision rates. Given the technique's successful application in various other malignancies, its implementation in NMSC diagnosis and treatment holds significant promise and warrants further research in clinical trials.

Acute Upper Extremity Ischaemia as a Result of Muscular Hypertrophy: The Popeye Syndrome.

Arterial entrapment syndrome (AES) at the elbow level is very rare. In cases of acute upper extremity ischaemia presenting in middle-aged patients with evident muscular hypertrophy, AES should always be included in the differential diagnosis. A thorough clinical examination should always follow, particularly when symptoms appear after reported strenuous upper extremity activity, and emergent surgical decompression is mandatory to avoid thrombotic complications in the affected arm in the future.

The Association of Vitamin D with Non-Melanoma Skin Cancer Risk: An Umbrella Review of Systematic Reviews and Meta-Analyses.

Background and Objectives: Previous studies revealed the anti-angiogenic, antiproliferative, and anti-inflammatory effects of Vitamin D (VitD) on cancer cells. Although this body of evidence supported the correlation of high VitD levels with reduced incidence rates for various malignancies, contradictory results were reported regarding non-melanoma skin cancer (NMSC). The aim of this overview was to summarize the available evidence from the existing pool of systematic reviews and meta-analyses, focusing on VitD serum status, dietary intake, and VitD receptor (VDR) polymorphisms in correlation to NMSC incidence. Materials and Methods: A literature search in electronic databases was conducted from inception to January 2023. The inclusion criteria were systematic reviews and meta-analyses published in peer-reviewed journals, evaluating VitD serum levels, dietary and/or supplementary intake, or VDR gene polymorphisms, and reporting data on NMSC. Results: A total of 10 studies were included in the data analysis models. A positive association between VitD serum levels and NMSC is highlighted. However, dietary/supplementation of VitD does not exhibit a likewise strong linkage to NMSC. Despite the contradictory findings, VDR polymorphisms may play a crucial role in the intricate NMSC pathogenesis. Conclusions: This umbrella review shows that high VitD levels are associated with increased NMSC incidence, potentially due to its direct correlation with increased sun exposure. Further research on VDR polymorphisms is suggested to explore their true effect size on NMSC risk.

Concomitant Reconstruction of Multiple Scalp Defects With One Rotational Flap.

The cornerstones of scalp reconstruction are provisions of adequate skin paired with a satisfactory cosmetic outcome without hairline distortion. Several techniques have been described over the years to reconstruct sizable defects. Currently, an individualized approach, based on the patient's medical status and needs, the defect characteristics, and the local tissue quality and availability, should be considered for an optimal outcome. The reconstruction of multiple scalp defects, by means of a well-planned rotational flap, is proposed as a viable option with many advantages. It enables concurrent reconstruction of the defects, obviates further surgical incisions, and elaborates surgical maneuvers, minimizing operative time and complications risk. A satisfactory esthetic outcome can be achieved.

Towards non-invasive monitoring of non-melanoma skin cancer using spatially offset Raman spectroscopy.

BCC (basal cell carcinoma) and SCC (squamous cell carcinoma) account for the vast majority of cases of non-melanoma skin cancer (NMSC). The gold standard for the diagnosis remains biopsy, which, however, is an invasive and time-consuming procedure. In this study, we employed spatially offset Raman spectroscopy (SORS), a non-invasive approach, allowing the assessment of deeper skin tissue levels and collection of Raman photons with a bias towards the different layers of epidermis, where the non-melanoma cancers are initially formed and expand. Ex vivo Raman measurements were acquired from 22 skin biopsies using conventional back-scattering and a defocused modality (with and without a spatial offset). The spectral data were assessed against corresponding histopathological data to determine potential prognostic factors for lesion detection. The results revealed a positive correlation of protein and lipid content with the SCC and BCC types, respectively. By further correlating with patient data, multiple factor analysis (MFA) demonstrated a strong clustering of variables based on sex and age in all modalities. Specifically for the defocused modality (zero and 2 mm offset), further clustering occurred based on pathology. This study demonstrates the utility of the SORS technology in NMSC diagnosis prior to histopathological examination on the same tissue.

Pleomorphic dermal sarcoma: it might be rare but it exists.

Pleomorphic dermal sarcoma (PDS) is a rare mesenchymal tissue tumor. Its differential diagnosis from similar tumors, such as low differentiated squamous cell carcinoma, fibrosarcoma, desmoplastic melanoma, atypical fibroxanthoma (AFX), may be difficult, as they have similar clinical and histological presentation. We present a case of an 83-year-old man exhibiting an exophytic scalp lesion. Excision of the lesion was performed, ensuring clear surgical margins and pathologic examination revealed an invasive pleomorphic dermal sarcoma. This case highlights a rare case of a large pleomorphic dermal sarcoma, and it discusses the histological, molecular features, its differential diagnosis and management of PDS.

Image Perceptual Similarity Metrics for the Assessment of Basal Cell Carcinoma.

Efficient management of basal cell carcinomas (BCC) requires reliable assessments of both tumors and post-treatment scars. We aimed to estimate image similarity metrics that account for BCC's perceptual color and texture deviation from perilesional skin. In total, 176 clinical photographs of BCC were assessed by six physicians using a visual deviation scale. Internal consistency and inter-rater agreement were estimated using Cronbach's α, weighted Gwet's AC2, and quadratic Cohen's kappa. The mean visual scores were used to validate a range of similarity metrics employing different color spaces, distances, and image embeddings from a pre-trained VGG16 neural network. The calculated similarities were transformed into discrete values using ordinal logistic regression models. The Bray-Curtis distance in the YIQ color model and rectified embeddings from the 'fc6' layer minimized the mean squared error and demonstrated strong performance in representing perceptual similarities. Box plot analysis and the Wilcoxon rank-sum test were used to visualize and compare the levels of agreement, conducted on a random validation round between the two groups: 'Human-System' and 'Human-Human.' The proposed metrics were comparable in terms of internal consistency and agreement with human raters. The findings suggest that the proposed metrics offer a robust and cost-effective approach to monitoring BCC treatment outcomes in clinical settings.

Antibiotic Prophylaxis in Reduction Mammaplasty: A Network Meta-Analysis.

BACKGROUND: Mounting evidence suggests that breast reduction surgery displays higher rates of surgical site infections (SSI) than initially presumed. Objective of this network meta-analysis is to evaluate the effectiveness of different antibiotic regimens in the prophylaxis from surgical site infections and delayed wound healing (DWH) following breast reduction. METHODS: A network meta-analysis was conducted using a predetermined protocol after searching the electronic databases MEDLINE, Scopus, the Cochrane Library and US National Institutes of Health Ongoing Trials Register from inception to July 2022. The included studies had to examine breast reduction in females with at least 1-month follow-up, receiving antibiotics in an intervention arm compared to a control arm. The quality of studies was assessed using the Cochrane risk of bias tool. A frequentist Mantel-Haenszel approach was adopted for the reported SSI rates while an inverse variance random effects model was used for the DWH rates. RESULTS: A total of 10 studies was included in the analysis involving 1331 patients. All but one study controlled for major risk factors, and no differences were observed in patients' baseline characteristics. Antibiotic administration significantly reduced the SSI rate after breast reduction, with the prolonged antibiotic regimen being the most efficacious (odds ratio [OR]: 0.36 [95%CI: 0.15-0.85]). No statistically significant reduction in delayed wound healing rate was revealed among the regimens. CONCLUSIONS: Antibiotics mitigate the SSI rate after breast reduction. This meta-analysis provides an evidence-based strategy to optimize antibiotic administration. Further research is needed though to examine antibiotic prophylaxis on delayed wound healing.

The 'Facelift' Flap Revisited.

The reconstruction of facial defects focuses on the preservation of function without compromising facial symmetry and esthetics. The aim of the study is to describe and evaluate a revised 'facelift' flap technique to reconstruct large defects of the cheek, temple, frontotemporal area, and zygomatic arch. A prospective, observational study of facial defect reconstruction by means of a 'facelift' flap was conducted from January 2019 to January 2022. The revised 'facelift' flap technique, based on the defect location and characteristics, is described. The postoperative outcomes and patient satisfaction were evaluated. The flap was applied to 34 patients with defect diameters ranging from 3 cm to 9 cm. The mean operation time was 67±17 minutes and the mean hospital stay was 1 day. No major postoperative complications were encountered; reoperation was not needed. High patient satisfaction rates were reported (9.6±0.5). The revised facelift flap is a reliable and safe method for the reconstruction of large defects of the cheek, temple, frontotemporal area, and zygomatic arch, based on local tissue availability that ensures satisfactory esthetic outcomes with undetectable scars.

The Efficacy of Wide-Awake Local Anesthesia No Tourniquet (WALANT) in Common Plastic Surgery Operations Performed on the Upper Limbs: A Case-Control Study.

BACKGROUND: The wide-awake local anesthesia no tourniquet (WALANT) technique is commonly used in elective hand surgery, whereas its application in plastic surgery is still limited. The aim of the study is to evaluate the feasibility and efficacy of WALANT in common plastic surgery operations performed on the upper limbs. METHODS: Patients who underwent those operations under WALANT were matched and compared with patients who had general or regional anesthesia without infiltration of a local anesthetic solution. All operations were performed by the same surgeon. Data from 98 operations were collected and analyzed for the total operation time, operation theatre time and complication and patient satisfaction rates. RESULTS: All operations under WALANT, mainly skin tumor excision and flap repair or skin grafting and burn escharectomy with or without skin grafting, were completed successfully. No statistical difference in total operation time and complication rates was revealed. Statistical significance favoring WALANT was identified regarding the mean operation theatre time and patient satisfaction. CONCLUSIONS: WALANT is an effective method for common plastic surgery operations performed on the upper limbs that is associated with better operation theatre occupancy and high patient satisfaction rates.
