RESUMO

Although many studies have been conducted to explore the relationship between mast cells (MC) and angiogenesis, comparison of this relationship with tumor necrosis has not been investigated to the best of our knowledge. Therefore, the relationship between MC and neovascularization in stomach, lung and ovarian malignant epithelial tumors (165 cases) in necrotizing or non-necrotizing cases was explored in this study. We immunohistochemically studied anti-mast cell tryptase antibody for MC and anti-CD34 antibody for vascular structures. MCs in the intra- tumoral and peritumoral fields, as well as vascular structures with luminal and monocellular appearances in the intratumoral field, were counted in each sample. Ten magnification fields were analyzed for each sample. In stomach and lung cases, the non-necrotizing group exhibited a greater number of MC and vascular structures in total. In ovarian cases, more MCs were counted overall in the necrotizing group, but there were fewer vascular structures. The increase in the number of MC and vascular structures in lungs and stomach in the non-necrotizing group supports the theory that MCs are involved in tumor progression. Necrosis, which can be induced on the basis of restricted neovascularization through inhibition of MCs in lung and stomach tumors, may be a treatment method.

RESUMO

Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction. In this study, we aimed to present our clinical experience in the treatment of five patients with SMAS, which is a rare clinical condition requiring surgery. Patients and methods The retrospective study included five patients who were treated due to SMAS at our clinic between January 2010 and January 2014. Results All the patients were underweight, with a mean BMI of 15.73 (14-16). The clinical symptoms included epigastric pain after food intake, large volume bilious emesis, early satiety, failure to gain weight, indigestion, esophageal reflux, sense of fullness, and persistent weight loss. SMAS was diagnosed using barium meal studies, upper gastrointestinal endoscopy, abdominal ultrasonography, and CT angiography. Four patients underwent duodenojejunostomy and one patient was managed with gastrojejunostomy. No complication was observed during the postoperative period, and all the patients achieved significant improvement in symptoms. Conclusion SMAS is a rare cause of UGS obstruction, and the diagnosis of SMAS is often delayed. SMAS should be suspected in the differential diagnosis of the patients with unsubstantiated symptoms of persistent nausea, emesis, and significant weight loss.

RESUMO

PURPOSE: To investigate the therapeutic effects of ellagic acid on L-arginin induced acute pancreatitis in rats. METHODS: Thirty-two were split into four groups. Group 1 (control) rats were performed only laparotomy, no drugs were administered. Group 2 (control+EA) rats were administered 85mg/kg EA orally. Rats were sacrificed by cardiac puncture 24 hours after the administration. Group3 (AP) 24 hours after intraperitoneal L-arginine administration, rats were sacrificed by cardiac puncture. Group 4 (EA)-(AP): 85mg/kg EA was administered orally after the L-arginine administration. 24 hours later, rats were sacrificed by cardiac puncture. Serum TNF-α, IL-1ß, IL-6, total oxidative status (TOS), total antioxidant capacity (TAC), amylase levels were determined in all groups. RESULTS: Group 3 (AP) rats showed significantly raised TOS level as compared to Group1 (control) rats (p<0.001). Following the EA therapy, a decrease in TOS was observed in Group 4 (AP+EA). TAC levels were significantly raised in the Group 4 (AP+EA) compared to the Group 3 (AP) (p=0.003). Group 3 (AP) showed significantly increased TNF-α, IL-1ß and IL-6 serum levels as compared to Group 4 (AP+EA). Histopathological changes were supported our result. CONCLUSION: The healing effects of ellagic acid on inflammatory and oxidative stress were confirmed by histopathological and biochemical evaluations of the pancreatic tissue.

RESUMO

OBJECTIVE: The most common procedure to prevent seroma formation, a common complication after breast and axillary surgery, is to use prophylactic surgical drains. Ongoing discussions continue regarding the ideal time for removing drains after surgical procedures. In this study, we aimed to investigate factors that affect drain indwelling time (DIT). MATERIALS AND METHODS: From 2014 to 2015, a total of 91 consecutive patients with breast cancer were included in the study. The demographic characteristics of the patients, treatment methods, histopathologic features of the tumor, size of removed breast tissue (BS), tumor size (TS), number of totally removed lymph nodes (TLN), and metastatic lymph nodes (MLN), whether they had neoadjuvant chemotherapy, and the DIT were retrospectively recorded from the hospital database. RESULTS: The mean age of the patients was 48.9 years, and the mean DIT was 4.8 days. The mean size of breast removed was 17.3 cm and tumor size was 4.7 cm, and the mean number of metastatic lymph nodes was 3.3, and mean total number of lymph nodes was 14.1. Patients who had neoadjuvant chemotherahpy had longer DIT. There was a positive correlation between the BS, TS, TLN, MLN, length of hospital stay, and DIT. Linear regresion analysis revealed that the BS, TLN, and history of neoadjuvant chemotherahpy were independent risk factors for DIT. CONCLUSION: DIT primarily depends on BS, TLN, and history of neoadjuvant chemotherahpy. A policy for the management of removing drains to prevent seroma formation should thus be individualized.

RESUMO

OBJECTIVE: Due to a lack of sufficient data, the treatment protocols for male breast cancer are usually the same as those used for female breast cancer. The aim of the current study was to present our clinical experience with male breast cancer. MATERIALS AND METHODS: The records of 37 patients who were treated for male breast cancer in our hospital between 2004 and 2014 were reviewed retrospectively. The data of patients were recorded and analyzed. RESULTS: The mean age of the patients was 63.03±12.36 years. Thirty-three patients (89.2%) had invasive ductal carcinoma, two (5.4%) had ductal carcinoma in situ, and two had invasive lobular carcinoma (5.4%). The most common molecular subtype was luminal A (17 cases, 45.9%). Twenty-nine patients with male breast cancer underwent mastectomy and two underwent breast conserving surgery. Axillary lymph node dissection was performed in 25 patients. The most common surgical procedure was modified radical mastectomy. Distant metastases were present in 17 (45.9%) patients. Overall, the 5-year survival was 60%. The 5-year survival was 100% for those with stage 0-I disease, 87% for stage II, and 42% for stage III. The 3-year survival was 14% for stage IV. CONCLUSION: Patients with male breast cancer presented at an older age, a later stage, and with earlier metastasis. Early metastasis and death increases with increasing stage. Poor prognosis correlates with late admission. Data from different centers should be compiled and reviewed in order to determine a specific treatment protocol for male breast cancer; each paper published reveals new data.

RESUMO

AIMS: Minimally invasive parathyroidectomy (MIP) has become the first line of treatment for primary hyperparathyroidism caused by solitary parathyroid adenoma. In order to increase the sensitivity of high-resolution ultrasonography (hUS), surgeon performed ultrasonography (SUS) has been increasingly used preoperatively. However, a radiologist and surgeon performing ultrasonography (RSUS) has not been a usual practice. In this study, we aimed to evaluate the clinical contribution of RSUS on MIP. MATERIAL AND METHODS: From 2012 to 2014, a total of 30 consecutive patients (4 male, 26 female, mean age 48.87+/-14.52 years) with solitary parathyroid adenoma, were included in the study. All patients underwent preoperative hUS and Technetium-99m sestamibi scintigraphy. In patients, demographic characteristics, diagnostic tools used, levels of biochemical parameters, duration of operation, and length of hospital stay were recorded. RESULTS: Adenomas were successfully localized by US in all patients and the surgical approach was determined according to this localization. Parathyroidectomy with MIP was successfully performed under local anesthesia in all patients. Mean operation time was 19.87+/-3.35 min. Postoperative PTH and calcium values were significantly decreased. All patients were discharged from the hospital in the same day. None of the patients had complications such as recurrent laryngeal nerve injury, hematoma, or injury to nearby organs. None of the patients had drains placed. CONCLUSIONS: Adenoma is well localized by US and thus, MIP can be completed under local anesthesia. US provides a very important clinical contribution to the success of MIP. In addition to these, RSUS helps in determining the location of the incision and the shortest way to achieve the lesion; therefore, it provides a small incision and shortens duration of the operation with a minimal dissection.

RESUMO

Our objective for this study was to discuss the usability of mean platelet volume, which is associated with numerous vascular pathologies, in the early diagnosis of acute mesenteric ischemia. Acute mesenteric ischemia is an uncommon, life-threatening clinical condition mostly seen in the elderly. Early diagnosis of acute mesenteric ischemia and correction of blood circulation before necrosis occurs are important factors affecting prognosis. A total of 95 patients who underwent emergency surgery for acute mesenteric ischemia and 90 healthy volunteers as control group were included in this study. Age, gender, hemoglobin values, white blood cell counts, mean platelet volume, and platelet counts are recorded for evaluation. The mean platelet volume values were significantly higher in patients with acute mesenteric ischemia than in the controls (9.4 ± 1.1 fL and 7.4 ± 1.4 fL, respectively; P < 0.001). Receiver-operating characteristic analysis demonstrated a cutoff value of mean platelet volume as 8.1 fL (area under the curve, 0.862), a sensitivity of 83.2%, and a specificity of 80%. As a result, in the patients who are admitted to the hospital with acute nonspecific abdominal pain and suspected of having acute mesenteric ischemia, high mean platelet volume values in routine hemograms support the diagnosis of acute mesenteric ischemia.

RESUMO

We aimed to present our clinical experience with FG treatment. Fournier's gangrene (FG) is a rare but serious disease characterized by progressive necrosis in the genitourinary and perineal region. The retrospective study included 43 patients. Patients were divided into 2 groups as survivors and nonsurvivors. Included in the analysis were data pertaining to demographics, predisposing factors, comorbidities, results of bacteriologic analyses, number of debridements, duration of treatment, FG Severity Index (FGSI) score, fecal diversion methods (trephine ostomy or Flexi-Seal Fecal Management System-FMS), and dressing methods (wet or negative aspiration system). In the nonsurvivor group, urea, WBC, and age were significantly higher, whereas albumin, hematocrit, platelet count, and length of hospital stay (LOHS) were significantly lower compared to the survivor group. Mean FGSI was lower in survivors in comparison with nonsurvivors (5.00 ± 1.86 and 10.00 ± 1.27, respectively; P < 0.001). We conclude that FGSI is an important predictor in the prognosis of FG. Vacuum-assisted closure (VAC) should be performed in compliant patients in order to enhance patient comfort by reducing pain and the number of dressings. Fecal diversion should be performed as needed, preferably by using FMS. The trephine ostomy should be the method of choice in cases where an ostomy is necessary.

RESUMO

In this study, we aimed to compare the effects of dexpanthenol and N-acetylcysteine on wound healing. The wound healing process is a multifaceted sequence of activities associated with tissue restoration process. A number of investigations and clinical studies have been performed to determine new approaches for the improvement of wound healing. A total of 30 rats were divided into 3 equal groups. A linear 2-cm incision was made in the rats' skin. No treatment was administered in the first (control) group. Dexpanthenol cream was administered to the rats in the second group and 3% N-acetylcysteine cream was administered to the rats in the third group. The wound areas of all of the rats were measured on certain days. On the 21st day, all wounds were excised and histologically evaluated. The epithelialization and granulation rates between the groups were revealed to be similar in microscopic evaluations. Although the fibrosis was remarkable in the control group as compared with the other groups, it was similar in N-acetylcysteine and dexpanthenol groups. Angiogenesis rate was remarkable in the N-acetylcysteine group compared with the others. In multiple-comparison analysis, Dexpanthenol and N-acetylcysteine groups had similar results in terms of wound healing rates (P < 0.05), which were both higher than in the control group (P > 0.05). The efficacy of N-acetylcysteine in wound healing is comparable to dexpanthenol, and both substances can be used to improve wound healing.

RESUMO

INTRODUCTION: We aimed to analyze the approaches to the diagnosis and treatment of patients with fascioliasis in light of current literature. METHODOLOGY: Thirty-nine patients with fascioliasis admitted to the Surgery Clinic of Dicle Medical Faculty (Turkey) were included in this study. The demographic, clinical, diagnostic, treatment and outcome data were analyzed retrospectively. RESULTS: Abdominal pain (n = 37; 95%) and eosinophilia (n = 31; 79%) were the most common findings. Twenty-seven patients were diagnosed by clinical and radiological findings. Patients were treated with triclabendazole. Thirty-six (92.4%) of the patients improved after medical treatment. CONCLUSIONS: The presence of typical clinical, laboratory and radiological findings is sufficient for diagnosis. Triclabendazole administration is often an effective treatment, with improvements occurring over the course of a few months.
