Necl 4 and RNase 5 Are Important Biomarkers for Gastric and Colon Adenocarcinomas.

BACKGROUND There is a need to identify new prognostic factors that may be used in addition to the known risk factors in gastrointestinal adenocarcinomas. In this study, we aimed to determine the expression of Necl 4 and RNase 5 biomarkers in gastric and colon adenocarcinomas, as well as the prognostic efficacy of these biomarkers in gastric and colon adenocarcinomas. MATERIAL AND METHODS Ninety-two cases resected due to stomach and colon adenocarcinoma were included in the study. The expression of Necl 4 and RNase 5 biomarkers was evaluated by immunohistochemical staining of the stomach and colon normal mucosa and adenocarcinoma areas. RESULTS In colon adenocarcinomas, there was a significant association between Necl 4 and lymphovascular invasion, vascular invasion, and perineural invasion (p<0.05). There was a significant association between RNase 5 and histological differentiation in colon adenocarcinomas (p<0.05). There was no association between RNase 5 and Necl 4 in gastric or colon adenocarcinomas. CONCLUSIONS Necl 4 may have prognostic value in colon adenocarcinomas, but it is difficult to ascertain in gastric adenocarcinomas.

Application of fasciocutaneous V-Y advancement flap in primary and recurrent sacrococcygeal pilonidal sinus disease.

BACKGROUND: Pilonidal sinus disease is a common disease of young adults, which most frequently occurs in the sacrococcygeal region on the skin's midline. Various procedures, ranging from simple incision and curettage to complex flaps for natal cleft obliteration, have been described in the literature. MATERIAL/METHODS: We aimed to present the dermographic characters, post-operative complications, length of stay in hospital, time of return to daily activities, and recurrence rates of the patients in which we applied sinus excision and fasciocutaneous V-Y advancement flap due to primary complicated or recurrent sacrococcygeal pilonidal sinus disease. RESULTS: Patients with primary complicated and recurrent pilonidal sinus received a fasciocutaneous V-Y advancement flap in the general surgery service of our hospital. Eleven patients had recurrent disease. Thirty-seven patients received a unilateral V-Y flap and 8 patients received a bilateral V-Y flap. None of the patients had post-operative flap necrosis or wound opening. Two of the patients had a self-draining simple seroma and 3 of the patients had delayed wound healing in the perianal region of the incision, which was treated with dressing. The mean time required to return to daily activities was 7 days, and return to work took 17 days. In the mean 25-month follow-ups of the patients, no recurrences were detected. CONCLUSIONS: We think that fasciocutaneous V-Y advancement flap is an easily learned and practicable method that reduces the recurrences in the patients with primary complicated and recurrent pilonidal sinus, length of stay in hospital, and time to return to daily activities and work in the post-operative period.

The effect of Liv-52 on liver ischemia reperfusion damage in rats.

BACKGROUND: Liver ischemia reperfusion (I/R) damage which is frequently seen in clinical hepatobiliary surgeries has no effective treatment for it. Liv-52, known to have hepatoprotective effects, is a natural antioxidant drug licensed by the Ministry of Health of India. The aim of our study is to investigate the effect of Liv-52 on liver damage induced by I/R in rats. METHODS: Albino Wistar male rats were divided into three groups; liver I/R (IR), 20 mg/kg Liv-52 + liver ischemia reperfusion (LIR) and sham operation applied to control group (HG). Liv-52 was administered to the LIR group (n = 6) 1 h prior to I/R application and distilled water was given orally to IR (n = 6) and HG (n = 6) groups as a solvent. Ischemia was determined as 1 h, and reperfusion was identified as 6 h in animals. RESULTS: Increased levels of alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase, malondialdehyde, myeloperoxidase, and decreased levels of superoxide dismutase, and glutathione related enzymes caused by I/R application have been converged to healthy group level with Liv-52 treatment and the damage in liver tissue has been improved histopathologically. CONCLUSIONS: Liv-52 may be beneficial for preventing liver I/R damage in pre-surgery application.

Effect of taxifolin on oxidative gastric injury induced by celiac artery ligation in rats.

PURPOSE: To examine the effect of taxifolin on I/R induced gastric injury in rats using biochemical and histopatholohical methods. METHODS: Eighteen albino Wistar male rats equally grouped as; gastric I/R (I/R), 50 mg/kg taxifolin + gastric I/R (TAX+ I/R) and sham operation applied (SHAM). Ischemia induced for 1 hour, and reperfusion induced for 3 hours. RESULTS: Oxidant parameters like, Malondialdehyde (MDA) and Hydroxyguanine (8-OHdG) were higher, whereas total glutathione (tGSH) was lower in the I/R group according to SHAM group, histopathological findings such as marked destruction, edema, and proliferated dilated congested blood vessels were observed severely in the I/R group, whereas there was not any pathological finding except mild dilated congested blood vessels in the TAX+ I/R group. CONCLUSION: The taxifolin can be clinically beneficial in the treatment of gastric injury due to I/R procedure.

The effect of metyrosine on oxidative gastric damage induced by ischemia/reperfusion in rats. Biochemical and histopathological evaluation.

PURPOSE: To investigate the effect of metyrosine against I/R induced gastric damage in rats. METHODS: Eighteen albino Wistar male rats were divided into groups; gastric I/R (GIR), 50 mg/kg metyrosine+gastric I/R (MGIR), and sham (SG) groups. 50 mg/kg metyrosine was given to the MGIR group, and distilled water was given to the GIR and SG groups by the oral gavage. After 30 minutes, 25 mg/kg thiopental sodium was injected intraperitoneally. Ischemia was achieved for 1 hour by clamping the celiac artery of the MGIR and GIR groups, then reperfusion was achieved for 3 hours. After that, animals were killed with 50 mg/kg thiopental. Biochemical and histopathological examinations performed on the gastric tissues. RESULTS: Metyrosine decreased the MDA and MPO and the increased the tGSH and SOD. In addition, it reduced inflammation by suppressing the decrease of COX-1 and the increase of COX-2. Histopathologically, metyrosine decreased symptoms caused by I/R such as mucosal necrosis, hemorrhage, edema, PMNL infiltration, and dilated congested blood vessels. CONCLUSIONS: Metyrosine prevented the I/R induced oxidative stress in the gastric tissue. Metyrosine may be beneficial for gastric I/R injury.

Aggressive papillary adenocarcinoma on atypical localization: A unique case report.

INTRODUCTION: Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland tumor that is found on the fingers, toes, and the digits. To date, <100 cases have been reported in the literature. Apart from 1 case reported in the thigh, all of them were on digital or nondigital acral skin. CASE PRESENTATION: A 67-year-old Caucasian woman was admitted to the hospital due to a mass on the scalp. This lesion was present for almost a year. It was a semimobile cyctic mass that elevated the scalp. There was no change in the skin color. Its dimensions were 1.5 × 1 × 0.6 cm. The laboratory, clinic, and radiologic findings (head x-ray) of the patient were normal. It was evaluated as a benign lesion such as lipoma or epidermal cyst by a surgeon due to a small semimobile mass and no erosion of the skull. It was excised by a local surgery excision. The result of the pathologic examination was aggressive papillary adenocarcinoma. This diagnosis is synonymous with ADPA. CONCLUSION: In our case, localization was scalp. This localization is the first for this tumor in the literature. In addition, another atypical localization of this tumor (ADPA) is thigh in the literature. This case was presented due to both the rare and atypical localizations. That is why, in our opinion, revision of "digital" term in ADPA is necessary due to seem in atypical localizations like thigh and scalp.

A Rare Case of Isolated Cystic Hydatid of Thyroid Gland.

Hydatid cysts are most frequently localized within the liver and lungs, although they can also be found in highly vascularized tissues such as the brain, muscle, heart, pancreas, adrenal, and thyroid glands.A 65-year-old female patient was admitted to our clinic with complaints of a progressively growing mass that was compressing the surrounding tissues and causing respiratory distress. The pathological result was obtained as cytic hydatid.In patients with diagnosed hydatid cysts in the liver, systemic evaluation is necessary to rule out involvement of other organs. Among patients presenting with growths located in the neck, primary hydatid cyst of the thyroid gland must be considered in endemic regions.

Gossypiboma Mimicking a Mesenchymal Tumor: A Report of a Rare Case.

BACKGROUND: Gossypiboma is the term for a surgical complication resulting from foreign materials such as a surgical sponge or gauze that was accidentally left inside a patient's body. CASE REPORT: Here, we report the case of a 62-year-old woman with gossypiboma. She underwent surgery due to an abdominal mass that was preoperatively considered a tumor. Intra-postoperatively, it was diagnosed as gossypiboma. CONCLUSIONS: For the prevention of gossypiboma during the pre-operative and post-operative periods, counting sponges and surgical equipment must be done very carefully. If there is any doubt postoperatively, direct abdominal imaging may be helpful.

Giant Cutaneous Leiomyosarcoma Originating From the Abdominal Wall: A Case Report.

BACKGROUND: Leiomyosarcoma, a rare type of tumor, accounts for 5-10% of all soft tissue tumors. CASE REPORT: A 44-year-old male patient was admitted to the emergency service of our medical faculty with the complaints of fatigue and abdominal mass. CONCLUSIONS: The pathology result was leiomyosarcoma. Leiomyosarcoma of the skin is rare and our case is the largest such lesion reported in the literature.

Rare tumors of the gallbladder: Clear cell carcinoma.

INTRODUCTION: Gallbladder cancer is a rare tumor in the gastrointestinal tract has poor prognosis, low survival and is difficult to diagnose. The most common type of gallbladder cancer is adenocarcinoma, and the incidence of clear cell carcinoma is low. Mostly, it is difficult to determine whether the isolated tumor is a primary tumor in the gallbladder or a metastatic tumor from another region. Before accepting a clear cell carcinoma as a primary gallbladder tumor, the kidneys and other possible secondary focuses are clinically considered in terms of metastases. PRESENTATION OF CASE: Here, we present a rarely seen case of gallbladder clear cell carcinoma, which was diagnosed by pathological examination after the surgery. DISCUSSION: Prior to establishing that clear cell carcinoma is a primary gallbladder cancer, it is appropriate to clinically investigate possible secondary focuses, in particular the kidneys in terms of metastasis. CONCLUSION: Our goal in presenting this case was to emphasize the importance of taking an accurate medical history in patients with clear cell carcinoma, a rarely seen gallbladder cancer.

Incarceration of the hepatic lobe in incisional hernia: A case report.

INTRODUCTION: Incisional hernias are abnormal peritoneal outward pouch-like protrusions that develop due to defects that arise as a result of the disruption of the fascia's continuity after abdominal surgery. PRESENTATION OF CASE: A 77-year-old female patient presented to the emergency department of our hospital with complaints of abdominal swelling, abdominal pain, nausea and vomiting. The patient was recommended for surgery. It was decided that the primary fascia closure and onlay patch was the most appropriate approach. DISCUSSION: When the defect in the abdominal wall grows, the functionality of the related abdominal wall is disrupted thereby eliminating the dynamic structure of the abdominal wall. Incisional hernias lead to a significant number of job losses and morbidity and negatively affect quality of life. Moreover, the formations in the hernia pouch might lead to higher risk of strangulation and dysfunction. CONCLUSION: Subcutaneous herniation of the left lobe of the liver passing through the abdominal wall is a very rare condition.
