Clinical Pathological and Immunohistochemical Correlations in Gastric Cancer.

Due to its high aggressiveness and polyclonal tumor state, stomach cancer is considered a severe health problem. In this study, we analyzed Her2 and Ki67 in correlation with patient data for the possibility of prognostic factors. The study included 48 cases of gastric tumors that had been surgically treated in a period of five years. The percentage was statistically significant for intestinal-type adenocarcinomas located in the medio-gastric region (p = 0.05); in the diffuse subtype, there were no Her2 positive samples, and in the mixed subtype only one out of three samples was Her2 positive. Our results confirm the existing data, and we can conclude that this link can be considered a prognostic factor in the progression and treatment effectiveness.

A Histological Evaluation of the Efficiency of Using Periprosthetic Autologous Fat to Prevent Capsular Contracture Compared to Other Known Methods-An Experimental Study.

BACKGROUND: Capsular contracture remains a common complication in silicone breast implantation. The etiology, formation mechanisms, predisposing and favoring factors are still subjects of research. This study aims to demonstrate the effectiveness of using autologous fat introduced periprosthetically in preventing capsular contracture compared to other known methods: antibiotics and corticosteroids. METHODS: A cohort of 80 Wistar rats was included in the study, divided into four subgroups. All subjects received a silicone implant, implanted in a pocket created along the abdominal midline. The first subgroup served as the control group, with subjects having the implant placed without any treatment. For the second and third subgroups, the implants were treated with an antibiotic solution and intramuscular injections of dexamethasone, respectively. The subjects in the last subgroup received centrifuged autologous fat introduced periprosthetically. RESULTS: The subgroup with autologous fat exhibited a significantly smaller capsule thickness, which was poorly represented, with a smooth surface. The use of autologous fat for treating silicone prosthesis was linked with the lack of acute inflammation around the prosthetic site. CONCLUSIONS: Autologous fat helps to minimize the "non-self" reaction, which results in the development of a periprosthetic capsule consisting of mature collagen fibers interspersed with adipocytes.

Laparoscopic Approach to Primary Splenic Cyst: Case Report and Review of the Literature.

Splenic cysts are rare benign lesions of the spleen, often asymptomatic and incidentally discovered during imaging studies. While many splenic cysts remain asymptomatic and do not require intervention, surgical management becomes essential in cases of symptomatic cysts, large cysts, or when malignancy cannot be ruled out. Laparoscopic surgery has emerged as a minimally invasive and effective approach for treating splenic cysts, offering advantages such as shorter hospital stays, reduced postoperative pain, and faster recovery. In this case report, we describe our experience with laparoscopic surgery for a symptomatic splenic cyst in a young patient.

Severe Intentional Corrosive (Nitric Acid) Acute Poisoning: A Case Report and Literature Review.

Despite being one of the most debilitating conditions encountered in the field of toxicology, there is a lack of neutralization measures for the toxins involved in acute corrosive poisoning, and this promotes progressive contact injury of deep tissues after poisoning has occurred. Multiple controversies still surround management strategies during the acute phase of poisoning and the long-term follow-up of the patient. Here, we report a severe case of intentional poisoning with nitric acid complicated by extensive injury of the upper digestive tract, multiple stricture formation, and complete dysphagia. Serial endoscopic dilation and insertion of a jejunostomy feeding tube were necessary, and underlying psychiatric illness negatively affected the outcome of the patient. We conclude that an interdisciplinary approach is necessary to properly reduce the extent of lesions and sequelae induced by corrosion. Early endoscopic mapping of injuries is of major importance to better predict the evolution and possible complications of poisoning. Interventional and reconstructive surgical procedures may significantly improve the life expectancy and quality of life of patients following intoxication with corrosive substances.

What Can We Find Behind a Parietal Abscess? Case Report.

We report a rare case of a 71-year-old female who presented to the First Clinic of Surgery from "Sf. Spiridon" Hospital Iasi, Romania with a mass in the left iliac fossa that started to discharge a feculent secretion five days prior to presentation. The patient had a history of constipation, several episodes of hematochezia associated with significant weight loss over the past 6 months. Following evaluation, a diagnosis of enter cutaneous fistula secondary to a locally advanced sigmoid cancer was made. The patient underwent semi-elective resection of the sigmoid tumor (measuring 20 cm) with 10 cm safe margins, and of the involved lymph nodes and abdominal wall. A termino-terminal colo-rectal anastomosis was performed. The patient was discharged the 10th postoperative day after an uneventful evolution for oncological evaluation. The authors presented this case in order to illustrate the challenges associated with diagnostic and therapeutic management of advanced colorectal cancer that has been discovered through a parietal abscess.

E-cadherin expression in primary colorectal cancer and metastatic lymph nodes.

Colorectal cancer (CRC) is one of the most prevalent malignancies and fourth cause of cancer death worldwide but the current TNM staging system together with clinicopathological characteristics are not sufficient to identify cases that have a poor prognosis. The aim of the current study was to compare E-cadherin expression in primary CRC and lymph node metastases with the one exhibited by normal colic mucosa and normal lymph nodes, and to evaluate its association with disease severity. The authors retrospectively analyzed 65 patients that underwent colectomy for CRC at the First Surgical Clinic, "Sf. Spiridon" Emergency Hospital from Iassy, Romania, over a 10 years period, from January 2004 to December 2013. In all cases, immunohistochemical staining against E-cadherin was performed on primary CRC and associated lymph nodes slices. Primary CRC presented a higher rate (64.62%) of abnormal E-cadherin expression (no staining, cytoplasmic or mixed staining) compared to normal colic mucosa (16.67%) (p<0.001). Both primary CRC and corresponding metastatic lymph nodes displayed a predominantly membranous expression (pure or mixed) of E-cadherin (67.69% and 89.23%, respectively). Well and moderately differentiated tumors displayed an increased E-cadherin expression (44 of 56 cases) compared to poorly differentiated tumors that lacked E-cadherin expression in six out of nine cases. In conclusion, E-cadherin expression abnormalities in CRC are rather qualitative than quantitative and E-cadherin is an important marker of tumor aggressiveness and spreading potential.

LIVER METASTASIS OF A GASTROINTESTINAL STROMAL TUMOR OF LARGE BOWEL: CASE REPORT.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal malignancies of the digestive tract. We present the case of a 61-year-old male patient liver metastasis of a GIST with primary location at the level of sigmoid colon. Like in the majority of cases, the symptomatology in this patient has long been faint and when it became manifest, it was nonspecific. Imagery wise, the computer tomography (CT) scan was the most efficient, showing the origin of the tumor from large bowel, its dimensions, as well as the relations with the other abdominal viscera and the liver metastasis. Surgery in this patient was en-bloc, according to the principles of GIST and for the metastasis he followed treatment with Imatinib. The histological aspect is characterized by a proliferation of spindle cells positive for CD117 and CD34. Despite complete microscopic resection, the exhibit of liver metastasis remains an important relapse factor.

Effectiveness of the immunochemical fecal test (FIT) for detection of advanced adenomas in colorectal carcinoma screening in an asymptomatic population.

AIM: The aim of the study was to evaluate the benefit of the immunochemical fecal blood test (FIT) for detection of advanced adenomas. MATERIAL AND METHODS: We have conducted a screening study on a average-risk cohort of subjects, aged 50 -74 years. We used a rapid quantitative FIT to perform the screening. Colonoscopy was recommended in all participants with positive FIT. We assessed the participation rate and analyzed advanced adenomas detected in the screening examinations. RESULTS: Our study enrolled 1111 asymptomatic participants. Immunochemical test results were positive in 72 subjects (6.5%). Colonoscopy was performed by 50/72 (69.4%) subjects. The detection rate for advanced adenomas was 2.2%. A total number of 28 advanced adenomas were detected in 24 subjects, meaning 1.2 advanced adenoma/subject. Analyzing the 3 characteristics of advanced adenomas, we observed in our study that 25/28 adenomas (89.3%) had sizes > or = 10 mm, 11/28 adenomas (39.3%) were tubulovillous/villous and 19/28 adenomas (67.9%) had high dysplasia. The majority of advanced adenomas were found in the left colon as compared to the right colon: 71.4% vs. 28.6%. p = 0.0008. CONCLUSIONS: In our study was obtained a 2.2% detection rate for advanced adenomas, most of them (71.4%) being located in the left colon. The dominant feature of advanced adenomas detected was the size > or = 10 mm (89.3% of cases).
