Large Symptomatic Inguinoscrotal Seroma Occurred Early after Laparoscopic Total Extraperitoneal Hernia Repair (TEP): a Case Report and Literature Review.

Inguinoscrotal hernia (ISH) is an entity for which treatment is under debate. Open surgery is the standard approach, but the laparoscopic technique has a great outcome when used by experienced surgeons. Seroma is one of the complications following laparoscopic hernia repair for these scrotal hernias, which is due to the large hernia sac, usually transected, leaving in place a remnant of the sac. Conservative measures can be applied for the treatment of seroma; however, in symptomatic cases, puncture and aspiration of fluid are recommended. Sometimes, these seromas can reach a large size and require surgery to remove the remnant sac. Herein, we report the case of a 49-year-old male with a large seroma that occurred four days after the laparoscopic approach - total extraperitoneal repair (TEP) for inguinoscrotal hernia. Conservative measures failed, and because the symptoms were not alleviated, reintervention was opted for. The distal sac was excised and the patient recovered uneventfully. The six-month follow-up did not show any recurrence of the hernia or seroma. We emphasize the importance of sac management in large ISH cases and discuss seromas after laparoscopic hernia repair in such instances.

Solid Phase Oligo-DNA Extraction from Complex Medium Using an Aminated Graphene/Nitrocellulose Membrane Hybrid.

A hybrid material, consisting of commercially available nitrocellulose (NC) membrane non-covalently modified with amino-polyethylene glycol functionalized reduced graphene oxide (NH2-PEG-rGO) nanoparticles, was successfully synthesized for oligonucleotide extraction. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the modification of the NC membrane, revealing characteristic peaks of both compounds, i.e., NC and NH2-PEG-rGO. Scanning Electron Microscopy (SEM) exhibited morphological changes in the NC/NH2-PEG-rGO hybrid membrane, marked by the introduction of NH2-PEG-rGO particles, resulting in a distinctly smothered surface compared to the porous surface of the NC control membrane. Wettability assays revealed hydrophobic behavior for the NC/NH2-PEG-rGO hybrid membrane, with a water contact angle exceeding 90°, contrasting with the hydrophilic behavior characterized by a 16.7° contact angle in the NC membrane. The performance of the NC/NH2-PEG-rGO hybrid membrane was evaluated for the extraction of ssDNA with fewer than 50 nucleotides from solutions containing various ionic species (MnCl2, MgCl2, and MnCl2/MgCl2). The NC/NH2-PEG-rGO hybrid membrane exhibited optimal performance when incubated in MgCl2, presenting the highest fluorescence emission at 525 relative fluorescence units (r.f.u.). This corresponds to the extraction of approximately 610 pg (≈13%) of the total oligo-DNA, underscoring the efficacy of the pristine material, which extracts 286 pg (≈6%) of oligo-DNA in complex solutions.

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.

Assessment of the aortic tunica media histological changes in relation with the cause of death.

AIM: The authors set out to evaluate the correlations between three of the main morphological aortic parameters (elastic fibers - FE, collagen fibers - FCOL, and smooth muscle fibers - FM) and the cause of death. MATERIALS AND METHODS: Study groups included 25 cases died of a vascular disease (V_P), 37 cases died of a non-vascular disease (NV_P) and 28 cases died of a violent/suspect non-pathological cause of death (V_Dth), the latter group representing also the control group. Four aortic cross-sections (base, arch, thoracic, and abdominal regions) were collected during autopsy from the selected cases, fixed in 10% buffered formalin and first of all photographed together with a calibrating ruler. Then, they were embedded in paraffin, sectioned off at 4 µm and stained with Hematoxylin-Eosin (HE) and Orcein. The obtained histological slides were transformed into virtual slides. Fibrillary components amounts were using a custom-made software, developed in MATLAB (MathWorks, USA). Statistical tools used were Pearson's correlation test, t-test (two-sample assuming equal variances) and one-way analysis of variance (ANOVA) test. RESULTS AND DISCUSSIONS: The amounts of the three fibrillary components of the aortic tunica media had a synchronous variation in all aortic regions in each of the three groups, excepting FCOL in the group of patients died from vascular pathology, which presented only a trend of synchronous variation along the aorta. FE had their lowest values and FCOL had their highest values in patients died from vascular pathology. FCOL had always higher levels than FE in people died from any pathological condition, vascular or non-vascular. FM had always at least two times lower level than that of the other types of fibers, regardless of whether the person died due to a pathological condition or not. CONCLUSIONS: The different pathological conditions causing death are influencing the fibrillary composition of aortic tunica media. Further studies are required to reveal other changes in the morphology of aortic wall in particular and vascular wall in general that could be related with different pathological conditions affecting the entire organism.

Spindle Cell Rhabdomyosarcoma of the Inguinal Region Mimicking a Complicated Hernia in the Adult-An Unexpected Finding.

Rhabdomyosarcoma is a rare tumor that is diagnosed mostly in children and adolescents, rarely in adults, representing 2-5% of all soft tissue sarcomas. It has four subtypes that are recognized: embryonal (50%), alveolar (20%), pleomorphic (20%), and spindle cell/sclerosing (10%). The diagnosis of rhabdomyosarcoma is based on the histological detection of rhabdomyoblasts and the expression of muscle-related biomarkers. Spindle cell/sclerosing rhabdomyosarcoma consists morphologically of fusiform cells with vesicular chromatin arranged in a storiform pattern or long fascicles, with occasional rhabdomyoblasts. Also, dense, collagenous, sclerotic stroma may be seen more commonly in adults. We present a rare case of an adult who presented to the hospital with a tumor in the left inguinal area, was first diagnosed with a left strangulated inguinal hernia and was operated on as an emergency, although the diagnosis was ultimately a spindle cell rhabdomyosarcoma of the inguinal region.

Right Transcephalic Ventriculo-Subclavian Shunt in the Surgical Treatment of Hydrocephalus-An Original Procedure for Drainage of Cerebrospinal Fluid into the Venous System.

The objectives of this article are to present an original surgical procedure for the temporary or definitive resolution of hydrocephalus, in the case of repeated failure of standard treatment techniques, and to present a case that was resolved using this surgical technique. MATERIALS AND METHODS: We present the case of a 20-year-old male patient with congenital hydrocephalus who underwent a number of 39 shunt revisions, given the repetitive dysfunctions of various techniques (ventriculo-peritoneal shunt, ventriculo-cardiac shunt). The patient was evaluated with the ventricular catheter externalized at the distal end and it was necessary to find an emergency surgical solution, considering the imminent risk of meningitis. The patient was also associated with the diagnosis of acute lithiasic cholecystitis. RESULTS AND DISCUSSIONS: The final chosen solution, right ventriculo-venous drainage using the cephalic vein, was a temporary surgical solution, but there are signs that this procedure can provide long-term ventricular drainage. CONCLUSIONS: Transcephalic ventriculo-subclavian drainage represents an alternative technical option, which can be used when established options become ineffective.

Colorectal Cancer-The "Parent" of Low Bowel Obstruction.

Introduction: Despite the improvement of early diagnosis methods for multiple pathological entities belonging to the digestive tract, bowel obstruction determined by multiple etiologies represents an important percentage of surgical emergencies. General data: Although sometimes obstructive episodes are possible in the early stages of colorectal cancer, the most commonly installed intestinal obstruction has the significance of an advanced evolutionary stage of neoplastic disease. Development of Obstructive Mechanism: The spontaneous evolution of colorectal cancer is always burdened by complications. The most common complication is low bowel obstruction, found in approximately 20% of the cases of colorectal cancer, and it can occur either relatively abruptly, or is preceded by initially discrete premonitory symptoms, non-specific (until advanced evolutionary stages) and generally neglected or incorrectly interpreted. Success in the complex treatment of a low neoplastic obstruction is conditioned by a complete diagnosis, adequate pre-operative preparation, a surgical act adapted to the case (in one, two or three successive stages), and dynamic postoperative care. The moment of surgery should be chosen with great care and is the result of the experience of the anesthetic-surgical team. The operative act must be adapted to the case and has as its main objective the resolution of intestinal obstruction and only in a secondary way the resolution of the generating disease. Conclusions: The therapeutic measures adopted (medical-surgical) must have a dynamic character in accordance with the particular situation of the patient. Except for certain or probably benign etiologies, the possibility of colorectal neoplasia should always be considered, in low obstructions, regardless of the patient's age.

Particular aspects of treating rectal cancer: The watch and wait approach.

Background: Rectal cancer is one of the most common malignant pathologies worldwide. Currently, the standard treatment of this pathology consists of radio-chemotherapy followed by low anterior resection with total mesorectal excision or abdominoperineal proctectomy for medium/low rectal cancer. Objectives: In recent years, another treatment strategy has been proposed, stemming from the finding that up to 40% of patients receiving neoadjuvant treatment had a complete pathological response. This method, also referred to as the watch and wait approach, implies delaying surgery and following a rigorous protocol for patients who have developed a complete response to neoadjuvant treatment with a good oncologic outcome. The objective of this study was to highlight the merits of this approach in selected patients. Case Reports: In this study, we present two patients with low-rectal tumors who developed complete response post neoadjuvant therapy and for whom the watch and wait protocol has been applied over the past 4 years. Conclusion: Although the watch and wait protocol appears to be a feasible option in the management of patients with a complete clinical and pathological response post neoadjuvant therapy, more prospective studies and randomized trials comparing this approach with standard surgical treatment are required before establishing it as the standard of care for distal rectal cancer. Therefore, establishing universal criteria for the selection and assessment of the patients with a complete clinical response following neoadjuvant treatment is required.

Surgical Outcome in Bilateral Inguinal Hernia Repair: Laparoscopic Total Extraperitoneal Approach (TEP) as Best Approach?

Introduction: Bilateral inguinal hernia is a distinct entity in the inguinal hernia category. Open and minimally invasive techniques for the treatment of bilateral inguinal hernia have been previously described. If resources and surgeon expertise are available, guidelines recommend laparoscopic repair for this entity. Methods:We analyzed data from 83 patients who underwent laparoscopic inguinal hernia repair (total extraperitoneal repair - TEP) of 158 hernias (146 inguinal hernias and 12 other types). Patients had bilateral symptomatic hernias. Results:Male predominance, with a mean age of 56.7 years, was noted. Lateral hernias (according to EHS classification) were prevalent (71.08%). In the majority of cases (77.11%), meshes made up of a custom polypropylene monofilament mesh were used, followed by Bard 3D Max mesh and Ultralight mesh. Regarding postoperative complications, seroma was the most frequently encountered one in our series (7.23%), followed by urinary retention and 'feeling' of mesh (2.41%). Hydrocele, wound hematoma, cord hematoma and chronic pain were seen in 1.20% of patients. No wound infections were observed. The average operative time was 97.77 minutes (SD=17.08); when associated surgery was present, it prolonged the operative time, and we found statistical significance (p=0.002). Similarly, the presence of recurrent hernia extended the operative time, which was found to be statistically significant (p=0.003). The conversion rate in our data was 2.41%. Drainage, which was performed in 13 patients (15.66%), decreased the incidence of complications, especially seroma (p=0.026). The mean length of hospital stay was 2.93 days (SD=1.81), with most of the patients having been discharged on the second postoperative day (37.35%). Only one recurrence was identified (1.20%). Conclusion:The laparoscopic approach for bilateral inguinal hernia treatment is feasible and has been proven to be advantageous. Our study emphasizes that the TEP procedure has low rates of complications, conversion and recurrence; hence, we recommend bilateral hernia repair.

Surgical Approach to Bilateral Inguinal Hernia. A Case-Control Study.

Introduction: Bilateral inguinal hernia can be safely repaired simultaneously, open or minimally invasive, in an elective sce-nario. The choice of surgical approach depends on the patient's status, hernia characteristics, surgeons and patient preferences. Whether age criteria should be considered when selecting between the two approaches is still a matter of debate. Considering that there is no consensus regarding the best repair in bilateral inguinal herniorrhaphy, the aim of the study is to perform an analysis regarding elective surgical approach of patients with bilateral inguinal hernias. Material and Methods: To study the relationship between exposure to an open versus laparoscopic approach in patients with bilateral inguinal hernia, we conducted a case-control study. In our retrospective analysis, cases (23 patients) were the open-approach hernia repair, and controls (82 patients) were laparoscopic hernia repair. We analyzed two sets of variables: first, related to patient characteristics (age 65 years, BMI 30 kg/m2, smoking habit, HTA status, COPD status, DM status, use of anticoagulants, presence of neoplastic status) and second, variables related to hernia features (inguinoscrotal hernia, recurrent hernia and complicated hernia). Results: The mean age for cases was 73.26 (Ã+-12.99) years and that of controls, was 56.48 (Ã+-15.15) years. Univariate analysis demonstrated four variables with statistical significance: age 65 years, inguinoscrotal hernia, neo-plastic status, and anticoagulant use. When introduced into the multivariate analysis, we noted that only two variables, age 65 years (OR=4.183, 95% CI [1.289, 13.572], p=0.017) and use of anticoagulants (OR=38.876, 95% CI [1.305, 1158.011], p=0.035) reached statistical significance. Conclusion: This study demonstrates that when we refer to bilateral inguinal hernia repair, patients aged 65 years are at risk of having an open procedure at least fourfold more than patients aged 65 years. In addition, the use of anticoagulants increases the risk of open hernia repair 38 times more than that of minimally invasive repair for the same age group. Interestingly, in our study, hernia characteristics were not found to be associated with open hernia repair and age 65 years. In our study we found that age 65 years is associated with electing open hernia repair over minimally invasive repair, which can be linked to age-related risk factors. Further re-search is needed to investigate the impact of age and age-related risk factors on surgical outcomes of bilateral inguinal hernia repair.

Intestinal Stomas in Abdominal Surgery: Etiological Circumstances, Indications, High Gravity Factors and Complications.

This is a retrospective study of 264 intestinal stomas performed in the surgical unit of the Emergency Clinical Hospital "Bagdasar Arseni", Bucharest, within a 7-year period (2015-2021) aiming to evaluate their evolutive complications, risk factors, management and prevention strategies. Material and method. Colostomies: 218 (82.57%) cases, ileostomies 46 (17.43%) cases. Temporary stomas (103 cases or 39.02%) were isolated stomas of discharge in 45 cases and associated with other colorectal procedures in 58 cases. Postoperative complications included general systemic complications in 60 (22.72%) cases and local complications specific to stomas in 84 (31.81%) cases and common to abdominal surgery in 94 (35.60%) cases, which were solved by reoperation in 51 cases, with a reintervention rate of 19.31%. Stoma closures were performed in 34 (33.0%) of the 103 patients with temporary stomas. Of these, 26 (25.24%) patients died in the early postoperative period (< 30 days), the remaining 60 patients refused reintervention or were lost to follow-up. Conclusions. Faecal diversion still represents a therapeutic option for a wide range of benign or malignant digestive or extra-digestive abdominal diseases performed in emergency or scheduled surgeries, mostly for colorectal cancer and its complications.

Remodeling of the aortic wall layers with ageing.

AIM: The authors aimed to evaluate the correlations between the variation of two of the main morphological parameters of the aortic wall (intima and media thicknesses) and ageing. MATERIALS AND METHODS: Aortic cross sections (base region, cross region, thoracic region, and abdominal region) were collected from 90 cases of all ages died and autopsied in the hospital. Tissue samples were processed using the classical histopathological technique (formalin fixation and paraffin embedding) and stained with Orcein and Goldner's trichrome. The obtained histological slides were transformed into virtual slides. Intima and media thicknesses were determined on virtual slides using a custom-made software, developed in MATLAB (MathWorks, USA). RESULTS AND DISCUSSIONS: The intima layer underwent an obvious and continuous process of thickening both from the aortic base region to its terminal (abdominal) region and from young ages to old age. The processes were similar in men and women but almost always more pronounced in men than in women. The media layer underwent a thickness reduction process from the aortic base to the terminal (abdominal) region whereas with age, the thickness of the layer increased. This divergent profile of evolution was similar in both men and women but with some variations depending on either topography or ageing. CONCLUSIONS: Each of the main layers of the aortic wall revealed dynamic individual evolutionary profiles related to age, gender and topography along the aortic path. Studies must be continued in a more detailed, standardized and integrated way.

Epithelioid hemangioendothelioma - an unexpected diagnosis of a mediastinal tumor with extensive local thrombosis.

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor and the mediastinal localization is amongst the most infrequent. We present the case of a 37-year-old woman with a history of resected left thyroid tumor that presented to our department for evaluation of a left supraclavicular palpable mass in close contact with local vascular structures, and with heterogeneous contrast enhancement as described by computed tomography (CT) and magnetic resonance imaging (MRI). Considering the history of the patient, the presumptive diagnosis of thyroid tumor recurrence was established, and the patient was referred to surgical department. During procedure, we encountered important bleeding from a ruptured jugular vein branch, which we assumed to be a newly formed tumor blood vessel. After surgery (48 hours postoperatively), the patient developed important local thrombosis that encompassed the left internal jugular vein, left subclavian vein and the left brachiocephalic trunk that partially subsided after anticoagulant therapy. The histological examination revealed the presence of a vascular tumor proliferation of epithelioid endothelial cells that was characteristic of an EHE confirmed later on the immunohistochemical studies as Yes-associated protein 1-transcription factor E3 (YAP1-TFE3) subtype. In addition to the case report, some relevant information from the scarce literature data about mediastinal EHE were reviewed here.

A review of NTRK fusions in cancer.

The family of the neurotrophic tropomyosin kinase receptors (NTRK or TRK) is a part of the transmembrane tyrosine kinases responsible for neuronal development. The members of this receptor family are TRKA, TRKB and TRKC and they are encoded by the genes NTRK1, NTRK2 and NTRK3. Alterations of NTRK genes can induce carcinogenesis both in neurogenic and non-neurogenic cells. The prevalence of NTRK gene fusion is under 1% in solid tumors, but is highly encountered in rare tumors. The presence of NTRK 1 gene fusion is associated, in some types of neoplasia, with a favorable evolution, but the presence of NTRK 2 may be associated with a poor prognosis. The identification of cancer patients harboring NTRK gene fusions is constantly growing, especially with the advent of NTRK inhibitors. This has promisingly provided a rationale for personalized therapeutics that improved outcomes in settings with this signature.

Meropenem antibiotic therapy in acute secondary peritonitis, therapeutic effects superior to other therapies - experimental clinical and histopathological study in the laboratory animal.

AIM: A perforated peptic ulcer is the most common cause of peritonitis through the perforation of the digestive tube, which occurs in a percentage between 2% and 14% of patients diagnosed with peptic ulcer and being associated with a 10% to 30% mortality rate. MATERIALS AND METHODS: Considering the above, we imagined a study, using laboratory animals, in which we produced gastric perforations, then followed their evolution without antibiotic treatment and under antibiotic therapy with Cefuroxime 25 mg∕kg∕24 hours intravenously or Meropenem 40 mg∕kg∕24 hours intravenously, following the tissue changes both macroscopically and microscopically. RESULTS: The study revealed a mortality of 36.6%, most deaths (81.82%) occurred in the first 24 hours after the perforation, all subjects belonging to the group that did not receive antibiotic treatment and the group treated with Cefuroxime. From a clinical point of view (evaluation of the general condition), macroscopically and microscopically, a better evolution of the subjects who received antibiotic therapy can be observed, compared to those who did not receive antibiotic therapy, thus in the case of subjects who received antibiotic therapy, the absence or the presence of a small amount of intraperitoneal fluid, which has a serocitrine appearance, as well as the absence of macroscopic changes at the level of unaffected intraperitoneal organs, can be observed. Microscopically, it can be seen that in the subjects treated with Meropenem, changes in the parietal peritoneum were minimal. CONCLUSIONS: Antibiotic therapy with Meropenem in acute peritonitis has a survival rate comparable to peritoneal lavage and source control.

Diagnostic and Therapeutic Particularities in Abdominal Trauma Associated with Spinal Cord Injuries - Review of the Literature.

Post-traumatic morbid associations may evolve by themselves, or can interact, with effects of adding or potentiating gravity. Sometimes cumulative or potentiating effects are associated with clinical and paraclinical confusing manifestations induced by one of the components of the lesion complex, or by mutually aggravating effects. It is also the case of vertebromedular traumas associated with other post-traumatic lesions, where the neurological signal is distorted, and may induce particularities of associated lesions. Posttraumatic spinal shock, autonomic dysreflexia and motor, sensory and autonomous after effects, bring distortions of the neurogenic signal, which will significantly affect other traumatized territories, generating clinical manifestations and atypical reaction elements. The prototype of this post-traumatic morbid association is represented by the lesion complex vertebromedular trauma - abdominal trauma.

Anatomical remodeling of the aortic wall in relation with the cause of death.

AIM: The authors set out to evaluate the correlations between three of the main morphological aortic parameters (aortic diameter, intima, and media thickness) and the cause of death. MATERIALS AND METHODS: Study group included 28 people died of a cardiovascular (CV) disease and 62 people died of a noncardiovascular (NCV) disease. Four aortic cross-sections (base, cross, thoracic, abdominal) were collected during autopsy from the selected cases, fixed in 10% buffered formalin and photographed together with a calibrating ruler. Then, they were processed using the classical histopathological (HP) technique (formalin fixation and paraffin embedding), stained with Hematoxylin-Eosin (HE) and Orcein, and the obtained histological slides were transformed into virtual slides. Aortic diameters were determined on calibrated photos using a custom-made software, developed in MATLAB (MathWorks, USA). Intima and media thicknesses were determined on virtual slides using a dedicated image analysis software. RESULTS AND DISCUSSIONS: The most frequent CV causes of death were the ischemic heart diseases and the most frequent NCV causes of death were the inflammatory diseases. Aortic diameter decreased from the aortic origin till the aortic end, with larger values in women than in men and in CV diseases than in NCV diseases. The difference in the remodeling of the aortic diameter between the two groups is smaller towards the abdominal region. Intima thickness increased from the aortic origin till the aortic end and was larger especially in women died of CV diseases, whereas in men there were some shifts at the extremities of the aorta. The difference in the remodeling of the intimal thickness between the two groups is extremely variable. Media was thicker in almost all of its segments in CV group than in NCV. It was a divergent evolution of the correlation degree trends in the two groups. CONCLUSIONS: The three morphological parameters of the aorta (diameter, intima, and media thicknesses) are more or less influenced by the pathological status that caused patient's death by the patient's sex and by the topographic region where the measurement was made.

Assessment of the aortic wall histological changes with ageing.

AIM: The authors aimed to quantitatively assess the variation with age of three of the main components of the aortic wall, namely elastic fibers (FE) and collagen fibers [FC(COL)], and smooth muscle cells (SMCs). MATERIALS AND METHODS: Four aortic cross sections (base, cross, thoracic, abdominal) were collected during autopsy from 90 cases of all ages, processed using the classical histopathological (HP) technique (formalin fixation and paraffin embedding) and stained with Orcein and Goldner's trichrome. The obtained histological slides were transformed into virtual slides. Quantitative measurements of the three components were made on identical regions of interest (ROIs) selected from two-paired slides stained with the above-mentioned techniques using custom-made software, developed in MATLAB (MathWorks, USA). RESULTS AND DISCUSSIONS: FE revealed an obvious decreasing general trend with age, present at all four levels of investigation. Smooth muscle fibers (FM) density showed almost no variation with age regardless of the level at which the measurement was made. FC(COL) density had an obvious increasing trend with age, expressed in all four aortic regions FE densities and FM densities were higher in men than in women, while FC(COL) densities were higher in women than in men in three of the aortic regions excepting, in all cases, the cross region. CONCLUSIONS: There were differences between men and women concerning the composition of aortic wall cellular and extracellular compartments. FE and FC(COL) dominated the age-related remodeling process of the aortic wall. The process evolved in the same way in all regions of the aorta. Studies need to be continued to define more clearly this complex process of vascular wall remodeling with aging.

Posttraumatic Injury Polymorphism - The Experience of an Emergency Surgical Department During 5 Years.

Introduction: Traumatic injuries are a major public health problem, being one of the main causes of death, the subsequent decline in the quality of life of the patients involved, as well as the costs of hospitalization in the health system. Material and Method: We conducted a 5-year retrospective study on 798 hospitalized patients with traumatic injuries, by collecting a series of general, clinical, imaging and biological parameters. Results: The results showed a higher proportion of male patients, the main lesion mechanism being represented by road accidents, followed by falls from another level. The most common traumatic intraabdominal parenchymal lesions were splenic, followed by hepatic and renal lesions. In addition to intraabdominal trauma, the lesion balance also included thoracic, spinal cord, head and limb injuries. A total of 288 patients underwent emergency surgery, but there were also cases of delayed surgical procedures or reoperations. We had 67 deceased patients. Conclusions: Trauma is a major public health problem, both socially and economically, being responsible for a significant number of deaths, but also in terms of the significant number of hospitalizations and the subsequent impact on the quality of life of those involved.
