Groin Hernia Repair during the COVID-19 Pandemic-A Romanian Nationwide Analysis.

Background and Objectives: Groin hernia repair surgery (GHRS) is among the most common elective interventions. The aim of this three-year nationwide study on GHRS is to provide a thorough analysis of the impact that the COVID-19 pandemic had on the Romanian Health System in regard to elective procedures. Materials and Methods: 46,795 groin hernia cases obtained between 2019 and 2021 from the DRG database using ICD-10 diagnostic codes. The data were collected from all 261 GHRS performing hospitals nationwide, including 227 public hospitals (PbH) and 34 private hospitals (PvH). The 42 variables taken into account were processed using Microsoft Excel 2021, applying Chi square, F-Test Two-Sample for variances, and Two Sample t-Test. The significance threshold considered was p < 0.001. Results: Of the grand total of cases, 96.2% were inguinal hernias, 86.8% were performed on men, 15.2% were laparoscopic procedures, and 6.88% were in PvH. Overall, due to the pandemic, the total number of GHRS decreased with 44.45% in 2020 and with 29.72% in 2021 compared to pre-pandemic year 2019. April 2020 shows the steepest decrease in GHRS (91 procedures nationwide). In the private sector, there was an opposite trend with increases in the number of cases by 12.21% and a 70.22% in both pandemic years. The mean admission period (MAP) for all procedures was 5.5 days. There was a significant difference between PbH and PvH (5.75 vs. 2.8 days, p < 0.0001). During the pandemic, the MAP in PbH decreased (6.02 in 2019, 5.82 in 2020 and 5.3 in 2021), remaining stable for PvH (2.9 days in 2019, 2.85 days in 2020 and 2.74 days in 2021). Conclusions: The COVID-19 pandemic significantly reduced the overall number of GHRS performed in Romania in 2020 and 2021, compared to 2019. However, the private sector thrived with an actual increase in the number of cases. There was a significant lower MAP in the PvH compared to PbH throughout the three-year period.

Preliminary study of some of the main intratumor stroma components in gastric carcinomas.

AIM: The relationship between stromal compartment and tumor behavior in gastric carcinomas is still poorly understood and defined. Therefore, the authors started, with this preliminary study, an analysis of stromal compartment morphology and behavior in tumors arising from gastric mucosa epithelium. MATERIALS AND METHODS: The study group included 75 patients operated for gastric carcinoma. Five parameters describing tumor morphology and behavior and eight parameters describing tumor stroma (TS) morphology were assessed. Histopathological examination included six serial sections of formalin-fixed, paraffin-embedded tumor tissue samples, stained with three classical stains and three antibodies to reveal the different parameters. For data comparison, Pearson's correlation test and the chi-squared (χ²) correlation test were used. RESULTS: Studied tumors were, usually, infiltrating, undifferentiated∕diffuse type, invasive in subserous spaces and with a Ki67 index higher than 20%. Collagen fibers dominated the stromal components, with a predominance of mature type and an average fibrillary index of 2.7. The whole amount of stromal components accounted for around one quarter of the tumor area. Mature collagen fibers were in opposite correlation with their immature counterpart, and both were in opposite correlation with smooth muscle fibers and expressed an opposite trend of correlation with components of vascular compartment. The whole amount of stromal components had divergent behavior with the components of vascular compartment. The latter expressed generally an opposite trend of correlation with individual fibrillary stromal components. We found only isolated relationships statistically significant between stromal components and tumor characteristics. CONCLUSIONS: TS is in a continuous remodeling process in relation to the evolution of tumor parenchyma, tumors less differentiated proving to have an immature stroma, with newly formed collagen fibers and higher vascular density. Further studies are required.

Preoperative Immunocite-Derived Ratios Predict Surgical Complications Better when Artificial Neural Networks Are Used for Analysis-A Pilot Comparative Study.

We aimed to comparatively assess the prognostic preoperative value of the main peripheral blood components and their ratios-the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR)-to the use of artificial-neural-network analysis in determining undesired postoperative outcomes in colorectal cancer patients. Our retrospective study included 281 patients undergoing elective radical surgery for colorectal cancer in the last seven years. The preoperative values of SII, NLR, LMR, and PLR were analyzed in relation to postoperative complications, with a special emphasis on their ability to accurately predict the occurrence of anastomotic leak. A feed-forward fully connected multilayer perceptron network (MLP) was trained and tested alongside conventional statistical tools to assess the predictive value of the abovementioned blood markers in terms of sensitivity and specificity. Statistically significant differences and moderate correlation levels were observed for SII and NLR in predicting the anastomotic leak rate and degree of postoperative complications. No correlations were found between the LMR and PLR or the abovementioned outcomes. The MLP network analysis showed superior prediction value in terms of both sensitivity (0.78 ± 0.07; 0.74 ± 0.04; 0.71 ± 0.13) and specificity (0.81 ± 0.11; 0.69 ± 0.03; 0.9 ± 0.04) for all the given tasks. Preoperative SII and NLR appear to be modest prognostic factors for anastomotic leakage and overall morbidity. Using an artificial neural network offers superior prognostic results in the preoperative risk assessment for overall morbidity and anastomotic leak rate.

Could there be an interplay between periodontal changes and pancreatic malignancies?

The term "periodontal disease" refers to a group of chronic inflammatory illnesses caused by specific microorganisms from subgingival biofilm, that affect the tooth-supporting tissues. Recent research has also shown that periodontal infection plays a role in aggravating systemic disease states at distal sites, reinforcing the significance of the oral cavity for general health. Additionally, it has been suggested that gastroenterological malignancies may be promoted by hematogenous, enteral or lymphatic translocation of periopathogens. In the past 25 years, the global burden of pancreatic cancer (PC) has more than doubled, making it one of the major causes of cancer-related mortality. Periodontitis has been linked to at least 50% increased risk of PC and it could be considered a risk factor for this malignancy. A recent study performed on 59000 African American women with a follow up of 21 years showed that participants who had poor dental health had higher chances of PC. The findings, according to researchers, might be related to the inflammation that some oral bacteria trigger. Regarding the mortality of PC, periodontitis considerably raises the chance of dying from PC. Microbiome alterations in the gut, oral cavity and pancreatic tissues of PC patients occur when compared to healthy flora, demonstrating a link between PC and microecology. Inflammation may also contribute to PC development, although the underlying pathway is not yet known. The function of the microbiome in PC risk has drawn more focus over the last decade. Future risk of PC has been linked to the oral microbiome, specifically increased levels of Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans and decreased relative abundance of Leptotrichia and Fusobacteria, suggesting that it may have an impact on the inflammatory condition by expanding, altering, and regulating the commensal microbiome. Patients who received periodontal treatment had significantly decreased incidence rate ratios for PC. By analyzing patterns in the microbiome composition throughout PC development and establishing strategies to enhance the cancer-associated microbial system, we can increase the efficacy of therapy and eventually find an application for the microbial system. The development of immunogenomics and gut micro-genomics in the life sciences will result in a significant advancement in our understanding of how microbial systems and immunotherapy interact, and it may also have intriguing therapeutic implications for extending the lifetime of PC patients.

Management of Littre Hernia-Case Report and Systematic Review of Case Reports.

Littre hernia is a rare type of hernia in which a Meckel diverticulum is found in the hernia sac. Given the rare nature of this disease, little data on demographics and surgical management exists. In this article, we provide a case report of a strangulated inguinal Littre hernia and perform a systematic review of the literature. The PubMed database was searched on 5 March 2022, and all cases of Littre hernia in adults that had English abstracts or full-text were analyzed. Our primary objective was to evaluate the surgical management and outcomes of this particular type of hernia, and our secondary objectives were to assess demographic characteristics, presentation particularities, and recurrence rates. We identified 89 articles with 98 cases, including our own. Results show a high prevalence of complications described intraoperatively, with strangulation being present in up to 38.46% of patients. The laparoscopic approach was utilized in patients with femoral, inguinal, and umbilical hernias. The most commonly performed type of resection was MD resection, followed by bowel resection, while a minority of cases (5.48%) remained unresected. Mesh repair was more frequently performed in patients with MD resection. A mortality rate of 8.7% in patients who underwent bowel resection was found. A relatively high number of reports of ectopic tissue (21.21%), ulceration (12.12%), and tumors (9.09%) were found. The average follow-up was 19.5 ± 10.29 months, with no hernia recurrence. In conclusion, most cases are admitted in an emergency setting, and intestinal obstruction is frequently associated. A minimally invasive approach can be an option even for complicated hernias. MD resection or bowel resection is usually employed, depending on the extent of ischemic lesions. Patients undergoing bowel resection may be prone to worse outcomes.

The Need for Oral Hygiene Care and Periodontal Status among Hospitalized Gastric Cancer Patients.

Poor oral hygiene leads to the accumulation of dental plaque, thus contributing to the initiation of periodontal disease (PD). Local infections can lead to systemic inflammatory responses, which are essential mediators for the evolution of systemic conditions or cancer tumorigenesis. Often, patients hospitalized with life-threatening and incapacitating disorders such as gastric cancer (GC) might lose interest in keeping their mouth healthy. This study evaluates oral hygiene, periodontal status, and the need for oral care and medical personnel to assist in achieving it in patients hospitalized with GC. This study was carried out on 25 patients with a diagnosis of GC, divided into two groups (GP-14 patients from the Gastroenterology Department, and SP-11 patients from the 1st Department of Surgery). Patients were examined on the day of admission (T0), the day of the medical procedure of endoscopy or surgery (T1), and the day of discharge (T2), recording the number of absent teeth, dental plaque (PI), bleeding on probing (BOP), probing depths (PPD), frequency of toothbrushing, and if the oral hygiene had been self-performed or assisted. Data were subjected to statistical analysis. Our results showed that, in both the GP and the SP group, there were strong and statistically significant correlations between PI and BOP measured on the last day of hospitalization and the period of hospitalization after the medical procedure. Longer hospital stays and the presence of surgery were risk factors for changing toothbrushing frequency. Results also highlight the need for a dentist to diagnose and eventually treat periodontal disease before and after hospitalization, and for a trained nurse who should help take care of the patient's oral hygiene during hospitalization.

Clinical-morphological profiles of esophageal carcinoma's main types.

AIM: The purpose of the study was to define and then to compare particularly the morphological profiles of the main morphological types of esophageal carcinoma (EC). PATIENTS, MATERIALS AND METHODS: The studied group included 46 operated EC patients. Few parameters were clinical (gender and age). The rest of them described both gross and histological features of the entire group and of the two main histological types of carcinoma (lesion' site, lateral extension, lesion dimensions, gross aspect, and histological type, and tumor grade, and stage). Stratification scales of cases were defined according to each parameter in order to compare the data and a statistical apparatus [Student's t-test and χ² (chi-squared) test] was used. RESULTS: The studied tumors were encountered mostly in mature adult and elderly men, usually in the lower segments of the esophagus. Many of them had between five and ten cm in the long diameter and produced stenosis. Most of them had infiltrating appearance combined often with protruding or∕and ulcerated aspects. Usually, the tumors were poorly differentiated and in stage III. The two main histological types of EC showed different morphological profiles. Data from the literature revealed sometimes wide ranges of variation for the studied morphological parameters. Our results were within these ranges of variation. CONCLUSIONS: ECs proved to be aggressive and late diagnosed tumors in general, with distinct morphological and behavioral profiles for the two main histological types. Comparisons with literature data confirmed many of our observations regarding the clinical and morphological aspects of both ECs as a whole and its histological types.

Indication of total parathyroidectomy for an Epstein syndrome patient with end-stage renal disease.

Epstein syndrome is an extremely rare genetic disorder characterized by the association of nephritis, deafness and megathrombocytopenia. We present the case of a 21-year-old patient diagnosed with Epstein syndrome and hyperparathyroidism secondary to chronic kidney disease. The main particularity of this case resides in the association between megathrombocytopenia and secondary hyperparathyroidism requiring surgery, which could lead to a series of concerns regarding the intra- and postoperative hemorrhagic risk of the procedure. Nevertheless, both the surgical procedure and the postoperative recovery were uneventful, suggesting that the lower threshold for preoperative thrombocyte count in megathrombocytopenia should be specifically considered on an individual case analysis.

Histopathological diagnosis and its correlations with anatomoclinical features, surgical approach and postoperative prognosis in sacral tumors.

INTRODUCTION: Sacral tumors encompass numerous histopathological types. They represent an uncommon pathology and, when diagnosed, they are often in advanced stage of the disease, becoming a therapeutic challenge. The correct treatment of a sacral tumor should be established by a multidisciplinary team that will assess the exact anatomical, imagistic and histopathological characteristic of the tumors thus choosing an optimal surgical approach while taking into consideration the risk of recurrence. MATERIAL AND METHODS: We conducted a retrospective analysis of both primitive and metastatic sacral tumors in "Bagdasar-Arseni" Emergency Hospital, Bucharest, Romania, for a period of 10 years, studying demographic data, clinical signs, anatomical and histopathological features as well as surgical approach and postoperative prognosis. RESULTS: Sacral tumors were diagnosed with a peak incidence in the age group 60-69 years, being more frequent in women. Primitive sacral tumor was predominant and, in this subgroup, chordoma was the most frequent. Metastatic tumors appeared in older subjects. None of the histopathological types associated a preferred topography of the resection or increased resectability. Posterior surgical approach was chosen in most cases, total resection being a hard goal to accomplish due to the invasion of vascular and nervous structures. Bleeding was the most frequently reported incident, carcinomas recording the highest blood loss amongst primitive tumors. Overall prognosis was clearly favorable for subjects diagnosed with primitive sacral tumors. CONCLUSIONS: Interpreting imaging data in a clinical context, paying attention to histopathological examination and knowing each histological type characteristics is mandatory in choosing the surgical approach thus obtaining the best postoperative outcome possible.

Brachiobasilic arteriovenous fistula with transpositionof the basilic vein: a multicenter study.

BACKGROUND/AIM: The aim of this paper was to present our 3-year multicenter experience in creating a vascular access using the basilic vein. The third choice in creating vascular access is the brachiobasilic arteriovenous fistula (AVFs) with transposition of the basilic vein. MATERIALS AND METHODS: During 2010-2012, out of a total of 874 AVFs that were performed in our two centers, 54 were brachiobasilic fistulas (6.71%), performed on 54 patients. All surgical procedures were performed by two surgical teams, one for each center. There were no significant differences regarding the patients' age, sex, and comorbidities between the two centers. RESULTS: We reported a total of six postoperative complications (11.10%): two wound infections, two arm edemas, one hematoma, and one bleeding (due to a collateral ligature slippage), which required surgical intervention the same day. None of the other complications required another surgery. The first year patency rate was 89.79% (four fistulas failed due to thrombosis and one due to perforation) and the second year patency rate was 62.12%. CONCLUSION: The brachiobasilic AVF with transposition of the basilic vein, according to the latest guidelines, remains a well-documented and feasible third option in creating vascular access with better results than graft fistulas.

Diffuse large B-cell lymphoma and polycythemia vera discovered at the onset - a rare association and its possible importance in lymphoma prognosis.

UNLABELLED: Diffuse large B-cell lymphoma (DLBCL) represent the most frequently non-Hodgkin's lymphoma (NHL) (over 30%), especially in developing countries. Many associations of NHL with another neoplasia were described following chemotherapy or radiotherapy regimens. The coexistence of DLBCL with myeloproliferative neoplasms (MPNs) JAK2V617F positive at the onset was very rare reported in the literature. We describe a clinical case of a 52-year-old man who presented both diagnoses at the onset - DLBCL and MPN - polycythemia vera (PV) type. The patient was treated with two CHOP cycles (Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisolone) followed by six R-CHOP (Rituximab-CHOP) cycles, together with a platelet-reducing agent, achieving remission for 20 months, followed by a relapse which is under treatment. The clonally expansion of an abnormal pluripotent hematopoetic stem cell could be responsible for both, PV and DLBCL. However, recent reports suggested the possible involvement of two different clones. The clinical significance and the role of JAK2 mutation in the evolution of patients with NHLs, including DLBCL are still unknown. Further genetic and clinical studies have to point out common gene mutations for the two diseases and their connection with the diseases behavior under the treatment. CONCLUSIONS: The coexistence of NHLs and especially DLBCLs and MPNs JAK2 positive is very rare. Although DLBCL alone has good prognosis, other prognostic factors should be checked when it is associated with PV. The presence of JAK2V617F seems to be a candidate but whose role in DLBCL evolution, natural or under treatment has to be cleared up.

Comparative study of clinical-morphological profiles of different types of gastric carcinoma.

AIM: Gastric carcinoma shows considerable variation in the histological pattern and degree of differentiation. The aim of the study was to assess especially the morphological differences between gastric carcinomas revealing one morphological feature and those including two morphological features. MATERIALS AND METHODS: Two groups of patients were selected: Group 1, including 43 patients with tumors revealing only one architectural pattern, and Group 2, including 16 patients with two architectural patterns within the tumor. In addition to gender and age, the main morphological parameters were: lesion location and macroscopic appearance on the surgical excision sample and microscopic appearance of the surgical excision sample, assessed for architectural pattern, secretory properties and prognosis based on histological features, degree of tumor extension and the degree of tumor aggressiveness, using a wide range of histological and immunohistochemical stainings. All data were compared between the two groups using statistical tests. RESULTS AND DISCUSSION: Significant differences were observed between the values and distributions of morphological parameters in the two groups and were discussed comparatively. CONCLUSIONS: Tumors with two dominant histological aspects present simultaneously are a reality that cannot be argued but whose morphological and biological profile needs to be completed and validated.
