RESUMO
Introduction: The COVID-19 pandemic has had an influence on the number of patients presenting to the emergency department (ED) with surgical conditions. Aim: To evaluate the number of patients presenting with acute appendicitis (AA) and the percentage of complicated appendicitis before and after the COVID-19 disease outbreak. Material and methods: This is a retrospective study based on the data of all patients presenting with AA to the ED of a tertiary COVID referral university hospital in Greece. We analysed the number of patients treated with AA, patient characteristics, and the proportion of patients with complicated appendicitis, and we compared the 2 groups of patients treated 12 months before and 12 months after COVID-19 onset in Greece. Results: A total of 152 patients were included in this study. There was a significant decrease in the number of patients presenting with AA after COVID-19 onset in Greece. Respectively, 91 and 61 patients were subjected to appendectomy 12 months before and after COVID-19 onset. Comparing the 2 groups of patients, there was a statistically significant increase in the operation time (p = 0.01) after COVID-19 onset, whereas the percentage of complicated appendicitis, the duration of symptoms before presenting to the ED (< 24 h, > 24 h), and the type of operation (laparoscopic, open, converted) did not differ significantly between the 2 groups of patients. Conclusions: The number of patients presenting to the ED with AA decreased after COVID-19 onset, most likely because patients hesitated to seek help in a COVID-19 referral hospital.
RESUMO
Introduction: Pancreaticoduodenectomy is a major procedure. Delayed gastric emptying (DGE) is a frequent postoperative complication that is attributed to several factors. Aim: To investigate the probable association between perineural infiltrations and DGE, and the effects on overall survival. Material and methods: A total of 123 patients who underwent pancreaticoduodenectomy were enrolled in the study. Factors like the presence of perineural infiltrations and post-operative DGE along with age, gender, presence of postoperative fistula, and grade of fistula and postoperative haemorrhage were analysed, and survival analyses were conducted. Results: The presence of perineural infiltrations is statistically associated with DGE occurrence (p = 0.01). Moreover, the occurrence of DGE is statistically associated with male gender (p = 0.001), worse grade of postoperative fistula (p < 0.01), and the presence of postoperative haemorrhage (p = 0.03). There was no statistical association between the presence of perineural infiltrations and the other factors. Cox regression and Kaplan-Meier survival analyses showed that increased overall survival is associated with low age (p = 0.018 and p = 0.028, respectively), absence of perineural infiltrations (p = 0.005 and p = 0.003, respectively), better grade of postoperative fistula (p < 0.001), and absence of postoperative haemorrhage (p < 0.001). Multivariate analysis showed that independent prognostic factors for survival prognosis are perineural infiltrations, age, the presence of postoperative pancreatic fistula, and the presence of postoperative haemorrhage. Conclusions: This is the first study that proves a statistically significant association between the presence of perineural infiltrations and the occurrence of DGE. Moreover, perineural infiltrations are an important independent prognostic factor for overall survival, along with other clinical factors.
RESUMO
Parathyroidectomy for primary hyperparathyroidism (PHPT) could have poor outcomes, even with accurate preoperative localization of the adenomas, because their intraoperative localization can be challenging. Freehand single photon emission computed tomography (fhSPECT) is a new technique for radio-guided intraoperative navigation. Its use during parathyroidectomy could be useful and such data are limited. We herein present our experience on the feasibility of fhSPECT for intraoperative detection of abnormal parathyroid glands. We retrospectively reviewed the clinical data of 55 patients (30-77 years old) with PHPT due to parathyroid adenomas, that were subjected to parathyroidectomy from 12/2017 to 7/2022. In average, 111 ± 74 MBq of Tc-99 m Sestamibi were injected intravenously, approximately 2 h before the operation and fhSPECT was used to generate 3D images during parathyroidectomy. Measurements of PTH and calcium levels were performed preoperatively, postoperatively and 4-6 months after the procedure. FhSPECT successfully identified the parathyroid adenoma in all the patients. It took 3 min (median time) for fhSPECT to detect at least one radioactive spot in all patients. The mean duration of the operation was 66.6 ± 7.3 min. Forty-nine patients out of 55 had solitary and 6/55 had multiple adenomas, whereas 6/55 had ectopic abnormal parathyroid glands. None of the patients had persistent hyperparathyroidism during follow-up. To the best of our knowledge, this is the largest series of patients with PHPT that underwent fhSPECT assisted parathyroidectomy. Our data suggest that this navigation system is helpful in identifying parathyroid adenomas intraoperatively.
RESUMO
INTRODUCTION AND HYPOTHESIS: Despite exercise being the standard approach to diastasis recti abdominis (DRA) rehabilitation, there is no consensus on the most effective exercise routine and adjunct modalities for reducing DRA and improving functional parameters. The present study is aimed at investigating evidence for DRA rehabilitation in postpartum women, as well as knowledge gaps and areas for future research. METHODS: For this scoping review a systematic search was conducted in MEDLINE, AMED, CINAHL, Embase, ScienceDirect, Scopus, and PEDro up to November 2022. Selection criteria included studies investigating exercise therapy interventions both with and without adjunct modalities for postpartum DRA. Sample characteristics, diagnostic criteria, program design, and outcome measures were recorded. Critical appraisal of clinical trials was performed using PEDro classification. RESULTS: Twenty-eight studies were included: 14 clinical trials, 3 case series, and 11 observational studies. DRA exercises that focused on deep and superficial muscles, pelvic floor muscles, respiratory maneuvers, functional exercises, or alternative interventions (yoga, suspension training, hypopressive exercise) and adjunct modalities showed promising results in reducing the inter-recti distance and related dysfunction. However, there was great variability in diagnostic criteria and methods, DRA severity, time post-birth, and exercise program design. CONCLUSIONS: Reviewed studies provide valuable insights into exercise therapy, but it is important to recognize their limitations, as variability in diagnostic criteria, sample characteristics, and exercise program design hinder the generalizability of the findings. Further high-quality research is needed to strengthen the evidence in this area and provide reliable recommendations for clinical practice.

BACKGROUND/AIM: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with dismal prognosis. Genomic instability due to defects in cell-cycle regulation/mitosis or deficient DNA-damage repair is a major driver of PDAC progression with clinical relevance. Deregulation of licensing of DNA replication leads to DNA damage and genomic instability, predisposing cells to malignant transformation. While overexpression of DNA replication-licensing factors has been reported in several human cancer types, their role in PDAC remains largely unknown. We aimed here to examine the expression and prognostic significance of the DNA replication-licensing factors chromatin licensing and DNA replication factor 1 (CDT1), cell-division cycle 6 (CDC6), minichromosome maintenance complex component 7 (MCM7) and also of the ubiquitin ligase regulator of CDT1, cullin 4A (CUL4A), in PDAC. MATERIALS AND METHODS: Expression levels of CUL4, CDT1, CDC6 and MCM7 were evaluated by immunohistochemistry in 76 formalin-fixed paraffin-embedded specimens of PDAC patients in relation to DNA-damage response marker H2AX, clinicopathological parameters and survival. We also conducted bioinformatics analysis of data from online available databases to corroborate our findings. RESULTS: CUL4A and DNA replication-licensing factors were overexpressed in patients with PDAC and expression of CDT1 positively correlated with H2AX. Expression of CUL4A and CDT1 positively correlated with lymph node metastasis. Importantly, elevated CUL4A expression was associated with reduced overall survival and was an independent indicator of poor prognosis on multivariate analysis. CONCLUSION: Our findings implicate CUL4A, CDT1, CDC6 and MCM7 in PDAC progression and identify CUL4A as an independent prognostic factor for this disease.

Sentinel lymph node biopsy (SLNB) has become the standard of care for clinically node-negative breast cancer and has recently been shown by clinical trials to be also feasible for clinically node-positive patients treated with primary systemic therapy. The dual technique using both radioisotope (RI) and blue dye (BD) as tracers for the identification of sentinel lymph nodes is considered the gold standard. However, allergic reactions to blue dye as well as logistics issues related to the use of radioactive agents, have led to research on new sentinel lymph node (SLN) tracers and to the development and introduction of novel techniques in the clinical practice. Indocyanine green (ICG) is a water-soluble dye with fluorescent properties in the near-infrared (NIR) spectrum. ICG has been shown to be safe and effective as a tracer during SLNB for breast cancer and accumulating evidence suggests that ICG is superior to BD and at least comparable to RI alone and to RI combined with BD. Thus, ICG was recently proposed as a reliable SLN tracer in some breast cancer clinical practice guidelines. Nevertheless, there is lack of consensus regarding the optimal role of ICG for SLN mapping. Specifically, it is yet to be determined whether ICG should be used in addition to BD and/or RI, or if ICG could potentially replace these long-established traditional SLN tracers. This article is an updated overview of somerecent studies that compared ICG with BD and/or RI regarding their accuracy and effectiveness during SLNB for breast cancer.
RESUMO
Epithelial-mesenchymal transition (EMT), a transdifferentiation program whereby epithelial cells acquire mesenchymal phenotype, is essential during embryonic development. EMT has also been implicated in cancer progression by conferring migratory and metastatic potential, as well as cell plasticity and stem cell like traits, to cancer cells. Metaplastic breast carcinoma (MBC) is a rare aggressive type of breast cancer characterized by the presence of heterologous elements, typically by the existence of epithelial and mesenchymal components. Phyllodes tumors (PTs) are uncommon fibroepithelial neoplasms consisting of epithelial and mesenchymal elements. Although various hypotheses have been proposed on the pathogenesis of these biphasic tumors, there is growing evidence supporting the theory that PTs and MBC could both correlate with cancer related EMT. This review summarizes the existing literature on the emerging role of EMT in the pathogenesis of MBC and PTs. Both malignant PTs and MBC are characterized by poor prognosis. Therefore, several anti-EMT targeting strategies such as blocking upstream signaling pathways, targeting the molecular drivers of EMT and targeting mesenchymal cells and the extracellular matrix, could potentially represent a promising therapeutic approach for patients suffering from these aggressive neoplasms.

Over the last decades, the field of medicine has witnessed significant progress in artificial intelligence (AI), the Internet of Medical Things (IoMT), and deep learning (DL) systems. Otorhinolaryngology, and imaging in its various subspecialties, has not remained untouched by this transformative trend. As the medical landscape evolves, the integration of these technologies becomes imperative in augmenting patient care, fostering innovation, and actively participating in the ever-evolving synergy between computer vision techniques in otorhinolaryngology and AI. To that end, we conducted a thorough search on MEDLINE for papers published until June 2023, utilizing the keywords 'otorhinolaryngology', 'imaging', 'computer vision', 'artificial intelligence', and 'deep learning', and at the same time conducted manual searching in the references section of the articles included in our manuscript. Our search culminated in the retrieval of 121 related articles, which were subsequently subdivided into the following categories: imaging in head and neck, otology, and rhinology. Our objective is to provide a comprehensive introduction to this burgeoning field, tailored for both experienced specialists and aspiring residents in the domain of deep learning algorithms in imaging techniques in otorhinolaryngology.
RESUMO
BACKGROUND: Despite recent advances in epithelial ovarian carcinoma (EOC) treatment, its recurrence and mortality rates have not improved significantly. DNA hypermethylation has generally been associated with an ominous prognosis and chemotherapy resistance, but the role of DNA methyltransferases (DNMTs) in EOC remains to be investigated. METHODS: In the current study, we systematically retrieved gene expression data from patients with EOC and studied the immunohistochemical expression of DNMTs in 108 primary and 26 relapsed tumors. RESULTS: Our results showed that the DNMT1, DNMT3A, DNMT3B and DNMT3L RNA levels were higher and the DNMT2 level was lower in tumors compared to non-neoplastic tissue, and DNMT3A and DNMT2 expression decreased from Stage-II to Stage-IV carcinomas. The proteomic data also suggested that the DNMT1 and DNMT3A levels were increased in the tumors. Similarly, the DNMT1, DNMT3A and DNMT3L protein levels were overexpressed and DNMT2 expression was reduced in high-grade carcinomas compared to non-neoplastic tissue and low-grade tumors. Moreover, DNMT1 and DNMT3L were increased in relapsed tumors compared to their primaries. The DNMT3A, DNMT1 and DNMT3B mRNA levels were correlated with overall survival. CONCLUSIONS: Our study demonstrates that DNMT1 and DNMT3L are upregulated in primary high-grade EOC and further increase in relapses, whereas DNMT3A is upregulated only in the earlier stages of cancer progression. DNMT2 downregulation highlights the presumed tumor-suppressor activity of this gene in ovarian carcinoma.
RESUMO
Metastasis is a cancer-related systemic disease and is responsible for the greatest mortality rate among cancer patients. Interestingly, the interaction between the immune system and cancer cells seems to play a key role in metastasis formation in the target organ. However, this complex network is only partially understood. We previously found that IL-22 produced by tissue resident iNKT17 cells promotes cancer cell extravasation, the early step of metastasis. Based on these data, we aimed here to decipher the role of IL-22 in the last step of metastasis formation. We found that IL-22 levels were increased in established metastatic sites in both human and mouse. We also found that Th22 cells were the key source of IL-22 in established metastasis sites, and that deletion of IL-22 in CD4+ T cells was protective in liver metastasis formation. Accordingly, the administration of a murine IL-22 neutralizing antibody in the establishment of metastasis formation significantly reduced the metastatic burden in a mouse model. Mechanistically, IL-22-producing Th22 cells promoted angiogenesis in established metastasis sites. In conclusion, our findings highlight that IL-22 is equally as important in contributing to metastasis formation at late metastatic stages, and thus, identify it as a novel therapeutic target in established metastasis.

Aim Thyroidectomy is the most common operation in the field of endocrine surgery. The aim of this study was to compare the use of LigaSure vessel (LS) and harmonic scalpel (HS) in 1653 total thyroidectomies between January 2008 and March of 2023, with regards to analysis of surgical bleeding complications duration the hospital stay and operative surgical time. Methods It is a retrospective analysis of a prospectively maintained database. Patients have been categorized into two groups: Group A included 718 patients from January 2008 to May 2013 when LS was used, and the Group B included 935 patients from June 2013 to March 2023 when HS was used. Results From the total of 14 postoperative bleeding cases that occurred in patients of Group A, only in 4 of them it was necessary to have a reoperation. The other 10 cases involved minor haemorrhages, while from the total of 6 postoperative bleeding cases that happened to patients of Group B, there were 4 cases that needed a reoperation (p-value >0.05) and 2 patients with minor haemorrhages. The postoperative evaluation of minor bleedings revealed statistically significant differences between the two groups (p-value < 0.05). The average hospital stay was similar in the two groups. Conclusion Both devices exhibit identical safety profiles in thyroidectomies specifically regarding major bleeding complications that require reoperation. Additionally, HS was found to be more effective at achieving haemostasis, especially in the subgroup of patients with thyroid carcinoma. The results of the present study may be useful for high-volume centres performing numerous thyroidectomies every day.
RESUMO
Background: The immune system plays a pivotal role in cancer progression. Interleukin 22 binding protein (IL-22BP), a natural antagonist of the cytokine interleukin 22 (IL-22) has been shown to control the progression of colorectal cancer (CRC). However, the role of IL-22BP in the process of metastasis formation remains unknown. Methods: We used two different murine in vivo metastasis models using the MC38 and LLC cancer cell lines and studied lung and liver metastasis formation after intracaecal or intrasplenic injection of cancer cells. Furthermore, IL22BP expression was measured in a clinical cohort of CRC patients and correlated with metastatic tumor stages. Results: Our data indicate that low levels of IL-22BP are associated with advanced (metastatic) tumor stages in colorectal cancer. Using two different murine in vivo models we show that IL-22BP indeed controls the progression of liver but not lung metastasis in mice. Conclusions: We here demonstrate a crucial role of IL-22BP in controlling metastasis progression. Thus, IL-22 might represent a future therapeutic target against the progression of metastatic CRC.
RESUMO
Patients with end-stage renal disease in Greece are facing long waiting times to receive a kidney transplant from a deceased donor. Living kidney donation offers a valuable alternative that provides optimal outcomes and significantly expands the donor pool but still remains relatively underutilised. Developments around the world in the field of kidney transplantation mandate a change in current practice to include additional options for living donation through paired exchange, antibody-incompatible transplantation and other strategies, following careful consideration of the cultural and ethical factors involved in these complex clinical decisions. An increase in living donation rates may be achieved in several ways, including targeted campaigning to overcome potential barriers. Educating clinicians on transplantation will prove as equally important as informing patients and prospective donors but requires training and resources. Adoption of established practices and implementation of new strategies must be tailored to the needs of the Greek donor and recipient population. Local beliefs about donation, perception of associated risk and other social characteristics must be considered in the design of future strategies. Facilitating living donation in a safe environment with appropriate donor and recipient education will form the solid foundation of a new era of kidney transplantation in Greece.
RESUMO
Hepatocellular carcinoma (HCC) ranks among the five most common cancer entities worldwide and leads to hundred-thousands of deaths every year. Despite some groundbreaking therapeutical revelations during the last years, the overall prognosis remains poor. Although the immune system fights malignant transformations with a robust anti-tumor response, certain immune mediators have also been shown to promote cancer development. For example, interleukin (IL)-22 has been associated with HCC progression and worsened prognosis in multiple studies. However, the underlying mechanisms of the pathological role of IL-22-signaling as well as the role of its natural antagonist IL-22 binding protein (IL-22BP) in HCC remain elusive. Here, we corroborate the pathogenic role of IL-22 in HCC by taking advantage of two mouse models. Moreover, we observed a protective role of IL-22BP during liver carcinogenesis. While IL-22 was mainly produced by CD4+ T cells in HCC, IL-22BP was abundantly expressed by neutrophils during liver carcinogenesis. Hepatocytes could be identified as a major target of this pathological IL-22-signaling. Moreover, abrogation of IL-22 signaling in hepatocytes in IL22ra1flox/flox × AlbCre+ mice reduced STEAP4 expression-a known oncogene-in HCC in vivo. Likewise, STEAP4 expression correlated with IL22 levels in human HCC samples, but not in healthy liver specimens. In conclusion, these data encourage the development of therapeutical approaches that target the IL-22-IL-22BP axis in HCC.
RESUMO
Portal vein thrombosis is a common complication associated with malignancies such as hepatocellular carcinoma, with a dismal and negative impact on prognosis. A thorough literature search in Pubmed and Google Scholar, under the terms 'hepatocellular carcinoma AND portal vein thrombosis', regarding the surgical management of portal vein thrombosis was conducted by the authors, and the associated results are presented in this narrative review. Precise classification of portal vein thrombosis and identification of subgroups of patients that will benefit from surgery is of paramount importance. Evolution of novel surgical techniques in liver resection and associated low morbidity and mortality rates in specialized hepatobiliary centres worldwide have been linked with promising results from the adoption of surgical management in these patients, when compared to systemic chemotherapy or arterial chemoembolization management that has traditionally been followed in such cases.
RESUMO
INTRODUCTION/OBJECTIVE: Thyroid carcinoma (TC) accounts for one percent of all carcinomas, with a higher incidence in women. Although there is controversy on the selection of the best surgical treatment for differentiated TC, total thyroidectomy (TT) and subtotal thyroidectomy (STT) are still the two main surgical procedures. The aim of the present study was to evaluate the early complication rates of thyroidectomy in patients undergoing thyroid surgery at a tertiary hospital in Greece. Methods: A total of 306 patients with differentiated TC who underwent thyroid surgery were enrolled retrospectively. Patients were divided into two groups. Group A included 214 patients undergoing TT, whereas 92 patients (group B) underwent STT. Demographic details of patients, operating time, and early complications (hypoparathyroidism, hematoma, infection, temporary recurrent laryngeal nerve palsy) were noted. Results: There was no significant difference in the sex, age, and mean operating time between the two groups (P=0.47, P=0.55, and P=0.09, respectively). Either hematoma or wound infection occurred in 3 (1.4%) or 4 (1.87%) of the patients undergoing TT compared to two (2.17%) or three (3.26%) of the patients undergoing STT (P=0.63 and P=0.46, respectively). In addition, either hypoparathyroidism or temporary recurrent laryngeal nerve palsy was observed in 34 (15.89%) or 13 (6.07%) of the patients undergoing TT compared with eleven (11.96%) or nine (9.78%) of the patients undergoing STT (P=0.37 and P=0.25, respectively). Conclusions: The current study demonstrates that total thyroidectomy can be safely performed in patients with differentiated thyroid carcinoma without increasing the risk of early complications.

The perineal colostomy is a reconstruction method performed after abdominoperineal resection for rectal malignancy. In this technique, the permanent colostomy is not placed in the left quadrant of the abdomen, but in the perineum. According to the literature, this technique provides many advantages such as a higher degree of satisfaction and greater quality of life to patients. Although this method could be a good option in selected patients, physicians should always be aware of the disadvantages of perineal colostomy.
RESUMO
AIM: Hepatocellular carcinoma (HCC) is a common cause a cancer-related death. Focal adhesions (FAs) represent multiprotein complexes at integrin-mediated cell-extracellular matrix adhesion sites that orchestrate vital cellular functions. The heterotrimeric ILK-PINCH-PARVB (IPP) complex, RSU1, a PINCH binding protein and CTEN, a member of the tensin family of proteins exert a critical role in FAs, where they regulate important cancer related functions such as cell adhesion, migration, proliferation and survival. Previous studies implicate these FA proteins in liver pathophysiology but their detailed role in human HCC is not fully understood. Here in we investigated expression and function of IPP, RSU1 and CTEN in human HCC. METHODS: The expression of focal adhesion proteins was studied in human HCC by immunohistochemistry in relation to clinicopathological parameters, previous studied genomic instability markers and patient's survival. Effects on cell proliferation and FA proteins expression upon ILK inhibition and RSU1 silencing were also investigated in HCC in vitro. RESULTS: IPP complex and CTEN proteins are overexpressed while RSU1 expression is decreased in human HCC. CTEN expression correlates with reduced patients' survival while RSU1 represents an independent favorable prognostic indicator in human HCC. Nuclear ILK expression correlates with markers of genomic instability. Pharmacological targeting of ILK suppresses, while RSU1 silencing promotes cell growth of HCC cells in vitro, while in both experimental conditions expression and/or localization of focal adhesion proteins is deregulated. CONCLUSION: Our results suggest that FA signaling is implicated in hepatocellular carcinogenesis with prognostic significance. RSU1 seems to exert tumor suppressive functions in HCC and represents a novel favorable prognostic indicator.

Aim To present the experience from collective data regarding patients with retroperitoneal sarcomas that have been operated in and followed up by the University General Hospital of Patras in Rion, Greece, between 2009 and 2020. Methods A retrospective analysis of adult patients treated at our hospital with a diagnosis of primary retroperitoneal sarcoma who underwent tumour resection. Results Data from 29 patients were analysed. The mean age at diagnosis was 56.1 years; 55.2% of patients were male (n=16). Liposarcomas (on histology) were identified in 19 (65.5%) patients, leiomyosarcoma six (20.7%), and other histologic subtypes in four (13.8%) patients. Tumours >5cm were presented in 27 (93.1%) patients. Negative margins were attained in 13 (44.8%) of all patients who underwent surgical resection. Five (17.2%) patients received neoadjuvant radiation, four (13.8%) postoperative radiation, and three (10.3%) patients received both chemotherapy and radiation prior to surgery with the rest of the patients being treated with surgical excision alone. A 3-year follow-up was successful in 21 (72.4%) patients; five (23.8%) patients died. In total, 16 (55.2%) patients were found to have a local recurrence, with no significant difference in patients' age, gender, tumour size, histology, negative surgical margin (Ro) resection, neoadjuvant chemotherapy, or radiation therapy. There was a significant difference in the 3-year survival rate between patients having positive or negative surgical margins (p=0.027). Conclusion The higher 3-year survival rate in patients with retroperitoneal sarcomas when achieving Ro resection warrant further investigation with a larger sample size across different institutions.
