Abstract
OBJECTIVE This study aims to evaluate the accuracy of preoperative 18F-FDG PET CT in detecting axillary lymph node (ALN) metastases in patients with breast cancer. PATIENTS AND METHODS A retrospective analysis was performed on the medical records of 114 patients who underwent PET CT for breast cancer between January 2017 and January 2020. Clinicopathological features and the relationship between lymph node metastasis were evaluated. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated based on the PET CT findings compared to histopathological results. RESULTS Among the 67 patients included in this study, 29 were identified as having no axillary involvement, while 38 showed axillary involvement according to preoperative PET CT. Of the 34 patients with histopathologically confirmed metastatic lymph nodes, 28 had PET CT-detected axillary involvement, while 6 did not. Similarly, among the 33 patients without histopathological evidence of lymph node metastasis, 23 had no axillary involvement according to PET CT, while 10 showed axillary involvement. The calculated values were as follows: sensitivity = 82.4% (67-92%), specificity = 69.7% (53-83%), positive predictive value = 73.7% (62-83%), negative predictive value = 79.3% (64%-89%), and accuracy = 76.1% (64-86%). CONCLUSIONS The results suggest that preoperative 18F-FDG PET CT, particularly p SUVmax, can serve as an independent prognostic factor for ALN metastasis in breast cancer patients. Therefore, it may be beneficial for preoperative risk stratification and personalized treatment planning.

Abstract
Successful cryopreservation requires the addition of cryoprotective agents (CPAs). The addition of permeating CPAs, such as glycerol, is associated with some risk to the cells and tissues. These risks are both related to the CPA themselves (CPA toxicity) and to the volume response of the cell (osmotic damage). To minimize the potential for damage during cryopreservation, mathematical models are often employed to understand the interactions between protocols and cell volume responses. In the literature, this volume response is usually captured using ideal and dilute approximations of chemical potential and osmolality, an approach that has been called into question for cells in high concentrations of CPAs. To address this, the relevance of non-ideal and non-dilute models has been explored in a number of cell types in the presence of permeating CPAs. However, it has not been explored in erythrocytes, which have a cytosolic hemoglobin content of more than 20% by volume and are cryopreserved in 40% glycerol. Because hemoglobin has been suggested to be a highly non-ideal solute, if the non-ideal and non-dilute transport model is relevant to any cells, it should be relevant to erythrocytes. Here we investigate the use, and accuracy, of both the dilute and non-dilute models in predicting cell volume changes during CPA equilibration in erythrocytes, and demonstrate that using published values for the non-ideal and non-dilute model, applied to erythrocytes, leads to model predictions inconsistent with experimental data, whereas dilute approximations align well with experimental data.

Abstract
Aims and Background Soft tissue sarcomas (STS) of the retroperitoneum are rare tumors. Surgery remains the principal modality of therapy in the management of primary and recurrent retroperitoneal STS. However, little is known about the effect of regional chemotherapy using hyperthermic total abdominal perfusion (HTAP). We analyzed independent prognostic variables in 33 patients with STS in the retroperitoneum admitted from November 1990 through December 1996. Methods and Study Design Data regarding patients’ age, gender, tumor size, histological tumor type, tumor location, type of operation (primary or secondary surgery), extent of surgical management (marginal or extended), use of HTAP, tumor grade, and tumor stage according to the TNM classification were examined by univariate and multivariate analyses. Results All 33 patients underwent complete resections (marginal or extended). Eleven of them received locoregional chemotherapy by HTAP. The overall cumulative 5-year survival rates in patients with stage IIA and advanced disease were 82% and 22%, respectively (log-rank test, P <0.01). Using Cox's proportional hazard model, tumor stage, use of HTAP and type of operation were found to have significant influence on overall survival (P <0.05). Conclusions Our results showed that complete resection along with HTAP chemotherapy may improve survival in patients with retroperitoneal STS. These phase II data could be used to support the initiation of a phase III trial to test HTAP in patients submitted to complete resection of retroperitoneal STS.

Abstract
BACKGROUND Pneumothorax is defined as air in pleural space. The etiology of spontaneous pneumothorax (SP) is still under investigation and, despite many studies, remains uncertain. The aim of this study was to investigate the effects of the lunar cycle and daily weather changes on SP development. METHODS The data of patients admitted to our clinic with SP were analysed retrospectively. The daily atmospheric pressure, relative ratio of humidity and temperature in degrees Celsius of each day were obtained. The mean values for each day, from the first to the 29th day, of the synodic lunar cycle (SLC) were calculated for the five-year study period. The attacks were allocated to the appropriate day of an ideal 29-day SLC, irrespective of the calendar date. RESULTS A total of 131 patients who were admitted to our hospital with SP (130 males and 1 female with an average age of 32.4±12.2) were included in this study. The number of patients with SP showed a statistically significant correlation with mean atmospheric pressure (p=0.005), relative humidity (p=0.007) and outdoor temperature (p=0.02) but not with the SLC. CONCLUSIONS SP is significantly influenced by weather-related factors. Changes in atmospheric pressure, humidity and outdoor temperature had obvious effects on the development of SP. However, the SLC had no effect on SP.

Abstract
The glutathione metabolism contains crucial antioxidant molecules to defend the organisms against oxidants. Thus, the aim of this study was to investigate the response of the glutathione metabolism in the liver of freshwater fish Oreochromis niloticus exposed to metals (Cu, Cd, Cr, Pb, Zn) in different periods. Fish were exposed to metals (as 1 μg/mL) individually for 1, 7, and 14 days and subsequently antioxidant enzymes (glutathione peroxidase, GPX; glutathione reductase, GR and glutathione S-transferase, GST) and glutathione levels (total glutathione, tGSH; reduced glutathione, rGSH; oxidized glutathione, GSSG and GSH/GSSG ratios) in the liver were measured. There was no fish mortality during the experiments, except Cu exposure. The antioxidant enzymes responded differently to metal exposures depending on metal types and exposure durations. GPX activity increased only after Cd exposure, while GST activity increased following 7 days of all metal exposures. However, GR activity did not alter in most cases. Total GSH and GSH/GSSG levels generally decreased, especially after 7 days. Data showed that metal exposures significantly altered the response of antioxidant system parameters, particularly at day 7 and some recovery occurred after 14 days. This study suggests that the response of antioxidant system could help to predict metal toxicity in the aquatic environments and be useful as an "early warning tool" in natural monitoring studies.

Abstract
The size of a fish is an important factor in its physiology, and metal uptake is affected by animal physiology. In this study, small and large tilapias (Oreochromis niloticus) differing approximately twofold in length and fivefold in weight were compared for their antioxidant response. Both groups were exposed to Cu or Cr (1.0 μg/mL) in a freshwater (-80 mg CaCO3/L, conductivity 1.77 mS/cm) using 2 exposure protocols (20 μM for 48 h and 10 μM for 6 days). Following the exposures, the antioxidant enzyme activities (superoxide dismutase, SOD; catalase, CAT; glutathione peroxidase, GPX; glutathione reductase, GR and glutathione S-transferase, GST) and glutathione (GSH) levels were measured in the liver of fish. Results showed that small fish was affected from exposure conditions much more than large ones as their antioxidant parameters significantly decreased even in controls. Metal exposures of small fish caused significant increases in SOD and CAT activity in acute Cu or Cr exposures. Subchronic Cr exposure of small fish also caused significant increases in CAT, GPx and GST activities, while there was no significant change in Cu-exposed ones. Large fish, however, showed different antioxidant responses as their levels mostly decreased. This study demonstrated that the response of antioxidant system in the liver of tilapia varied in relation to fish sizes and emphasized using different size groups in environmental monitoring and also in evaluation of fish biomarkers.

Abstract
BACKGROUND Morgagni hernias are rare and constitute less than 2% of all diaphragmatic hernias. Treatment is primarily surgical and transthoracic or transabdominal route approach methods are amenable. In this study, we compared the results of our Morgagni hernia cases, which underwent either transabdominal or transthoracic method of surgery. METHODS We retrospectively analyzed the records of 20 patients we operated on for Morgagni hernias between 1997 and 2011 in our clinic. Age, sex, presenting symptoms, lesion location, diagnoses, applied surgical method, duration of the hospital stay, morbidity and mortality rates were reviewed. Six of the cases were (30%) approached via thoracotomy and 14 (70%) were laparotomy. The hernial sac was resected in all cases. Diaphragmatic defects were repaired using nonabsorbable sutures in all cases except in one case where prolen mesh used. RESULTS Thirteen cases (65%) were female and seven (35%) were male. Mean age was 44.1 +/- 25.3 years (1-73 years). Hernias were located on the right side in 18 cases, the left side in one, and bilaterally located in one case. Herniated organs were: omentum in 19 (95%), transverse colon in 18 (90%), small bowel in 4 (20%), stomach in 3 (15%), and left lobe of the liver in one (5%) case. No complication was observed in patients who underwent laparotomy, and wound infection occurred in one patient who underwent thoracotomy. Hospital stays in thoracotomy and laparotomy groups are 7 and 6.2 days, respectively. There were no mortalities observed. There was no recurrence during the follow-up of 36.4 months (10-116 months). CONCLUSION Our findings showed that both surgical methods have similar and satisfactory results. Although transthoracic approach was preferred in previous cases, the transabdominal approach was preferred in later ones because we assumed that the later procedure is less invasive for the patient. We prefer and propose the abdominal approach for the surgical management of Morgagni hernias.

Abstract
BACKGROUND Hydatid cyst disease is a major health problem in developing countries and it usually settles in the lungs in children. This study aimed to present pre-school children with lung hydatid cysts cases that underwent surgical treatment. METHODS The authors retrospectively investigated 42 consecutive pre-school patients who were diagnosed and surgical treated for hydatid cysts in their clinic between January 1998 and December 2011. RESULTS Seventeen (40.5%) patients were female and 25 (59.5%) patients were male. The average age of the patients was 5.2 +/- 1.3 (between 2-7 years). The most common symptoms were cough (74%), chest pain (26.2%), and fever (26.2%). Twenty-eight cases had cysts in only one lung; in five cases, the cysts were in a single lung and the liver, in six cases, in bilateral lungs and liver, and in three cases, in bilateral lungs. The average cyst diameter was 6.2 +/- 2.4 (2-12) cm. In five cases, there were combined interventions to the right lung and liver cysts with a transdiaphragmatic approach. Nine patients with bilateral hydatid cysts underwent operations. Muscle protector thoracotomies were performed in eight cases. Cystotomy and capitonnage were applied to all lung cysts. One patient underwent a bronchoscopy for postoperative atelectasis. In one case, postoperative fever was observed. There was no postoperative mortality. Postoperative average hospital stay was 7.2 +/- 2.1 (3-13) days. CONCLUSION Surgery is the definitive treatment for lung hydatid cysts. The most important way to protect against the adverse effects of a thoracotomy is to eliminate the routes of transmission.

Abstract
Pulmonary artery sling (PAS) is a rare congenital anomaly frequently accompanied by focal or long-segment tracheal stenosis. We presented a 34-year-old female patient with severe long-segment tracheal stenosis associated with PAS which was assessed with Multi Slice Computed Tomography (MSCT) consisting of axial, three dimensional and virtual bronchoscopic images of the airway. This case report discussed the management of her difficult airway condition during surgical cholecystectomy and thyroidectomy by using proseal- LMA and I-gel, respectively (Fig. 4, Ref. 10).

Abstract
Anthropogenic activities can increase the salinity of freshwaters and this may cause stress for fish and affect metal bioavailability. Oxidative stress biomarkers are of great interest due to their responses to environmental stressors which provide valuable data for biological monitoring of aquatic pollution. Thus, the individual and combined effects of salinity and metals (Cr, Pb) were investigated in the liver of freshwater fish Oreochromis niloticus in the present study. Fish were exposed to salinity (2 and 8 ppt) alone and salinity+metal (1 μg/mL Pb and Cr) combination exposures for 0, 1, 7 and 14 days and subsequently antioxidant enzymes (superoxide dismutase, SOD; glutathione peroxidase, GPX; glutathione reductase, GR and glutathione S-transferase, GST) activities and glutathione (GSH) levels in the liver were measured. Data showed that all the parameters varied in relation to metal species, exposure durations and salinity levels. Profound alterations on the measured parameters were detected at the lower salinity compared to the higher one. Salinity increase effectively stimulated the antioxidant parameters. The effects of salinity and metals on the measured parameters increased as the exposure duration prolonged. SOD was the most affected antioxidant parameter from both salinity and metals. Because metal and salinity stresses affect fish antioxidant system, this work suggests that the chemistry of freshwaters should be taken into account in natural monitoring for metal contamination in the field.

Abstract
AIM Mediastinal cysts are rare, forming 12-18% of all primary mediastinal tumors. The purpose of this study is to evaluate type, clinical properties, treatment modalities, and results of mediastinal cystic neoplasm in the light of available literature. PATIENTS AND METHODS We retrospectively investigated 29 patients who were diagnosed and surgically treated for mediastinal cysts in our clinic between January 1996 and May 2011. RESULTS Sixteen (55.2%) patients were male and 13 (44.8%) were female. The average age of the patients was 36.5 +/- 22.1 (17-77 years old). The mediastinal cysts comprised 11 (37.9%) bronchogenic cysts; seven (24.1%) hydatid cysts; four (13.8%) benign cystic teratomas; three (10.3%) pericardial cysts; one (5.3%) thymic cyst; one (5.3%) cyst of the thoracic duct; one (5.3%) enteric cyst; and one (5.3%) lymphangioma. Approach methods were thoracotomy in 18 (62.1%) cases; video-assisted thoracoscopicsurgery (VATS) in seven (24.1%) cases; median sternotomy in three (10.3%) cases; and anterior mediastinotomy in one case. Postoperative observations during the follow-up period showed chylothorax in one patient; pleural effusion in one patient; and the recurrence of a bronchogenic cyst in one patient five years after the operation. Postoperative mortality did not occur in any case. The average postoperative hospitalization period was 7.3 days (2-14 days). CONCLUSION A surgical approach to mediastinal cysts offers histological analysis, pathological diagnosis, curative treatment, and prevention from complications.

Abstract
PURPOSE In individuals with malignant disease, many qualitative and quantitative hormonal changes have been detected. Although there are many studies showing that there is a relationship between thyroid hormone disorders and certain tumours, no study investigating the association between oesophageal cancer and thyroid diseases has been reported. The present study was designed to evaluate whether there is a relationship between oesophageal cancer and thyroid hormones. METHODS In a prospective study conducted between December 2006 and February 2008, thyroid functions were studied in a group of 102 sequential patients with oesophageal cancer and a control group of 160 sequential patients without oesophageal cancer, presenting to the Thoracic Surgery Department of Ataturk University. Age, gender, tumour location and histological type in patients with oesophageal cancer were recorded. RESULTS Of 102 patients with oesophageal cancer, 21 (20.58%) had hyperthyroidism, 2 (1.96%) had hypothyroidism and 6 (5.88%) exhibited nodular/multinodular goitre on ultrasonography and computed tomography. In the control group, 8 patients (5.0%) had hyperthyroidism, 4 (2.5%) had hypothyroidism and 7 (4.38%) showed nodular/multinodular goitre. In patients with oesophageal cancer, the incidence of hyperthyroidism was found to be significantly higher compared to the control group (p < 0.001). CONCLUSION Data show that there may be an important relationship between oesophageal cancer and hyperthyroidism. We believe that thyroid hormone levels should be measured in all cases of oesophageal cancer. In further prospective and experimental studies, the physiopathology of this relationship can be fully explained.

Abstract
Most patients with esophageal carcinoma present in the advanced stage die from tumor invasion and widespread metastases. Because radical regimens are not appropriate for the majority of patients, and their expected survivals are as short as to be measured by months, the main aim of therapy is palliation with minimum morbidity and mortality. Among the palliative modalities are surgery, external radiotherapy or brachytherapy, dilatation, laser, photodynamic therapy, bipolar electrocoagulation tumor probe, and chemical ablation. The placement of self-expandable metallic stents is another method that improves dysphagia for these patients. In this study, the aim was to evaluate retrospectively the effectiveness of metallic stents deployed because of inoperable malignant esophageal stenosis and esophagotracheal fistulas. The results of 170 patients with 202 stents administered because of inoperable malignant esophageal stenosis and esophagorespiratory fistula between January 2000 and October 2008 at the Ataturk University, Department of Thoracic Surgery, were investigated. Despite epidemiological and clinical data, information regarding relief of dysphagia and quality of life were also examined. One hundred seventy patients with stents were between 28 and 91 years old (mean age 63.7 years+/-11.4 years). Ninety-seven were male and 73 were female. Stent indications were advanced tumors with distant metastasis (82 cases, 48.2%), unresectable tumors (51 cases, 30%), patients who cannot tolerate surgery or chemoradiotherapy (18 cases, 10.5%), local recurrence after primary therapy (1 case, 0.5%), esophagorespiratory fistulas from tumor or therapy (14 cases, 8.2%), and refusal of surgery (4 cases, 2.3%). Dysphagia scores evaluated by a modified Takita's grading system improved from 3.4 before the procedure to 2.6 afterward. The overall complication rate without chest pain was 31.7% (occurring in 64 cases). Mean survival was 177.7 days+/-59.3 days (2-993 days). Quality-of-life scores (The European Organization of Research and Treatment of Cancer QLQ C30) improved from 73+/-10.3 (57-85) to 112+/-12.6 (90-125). In therapy of malignant esophageal obstructions, metallic stents provide a significant improvement in dysphagia and require less frequent re-intervention according to other methods of dysphagia palliation such as dilatation, laser, and photodynamic therapy, nearly completely relieve esophagotracheal fistulas and improve quality of life to an important degree.

Abstract
Bronchogenic cysts are the most common form of congenital cystic lesions in the mediastinum. Of all cases with bronchogenic cysts, 1/3 are symptomatic. The symptoms vary depending on the location and compression of the adjacent structures of the cyst. Some mediastinal bronchogenic cysts can cause severe respiratory distress due to airway and vascular compression. We herein present a case with a bronchogenic cyst that required venoplasty to the superior vena cava (SVC) due to total occlusion of the SVC.

Abstract
Muco-epidermoid carcinomas (MECs) are typically located in the salivary, lacrimal and tracheobronchial glands. However, they can also be present in the oesophagus. Primary MECs of the oesophagus account for 0.05% to 2.2% of all cases of primary oesophageal cancer. Treatment for this tumour has primarily been surgical resection. In this report we present the surgical and pathological findings of a primary MEC of the oesophagus in an 82-year-old woman and review the management options for this tumour.

Abstract
Esophageal perforations are surgical emergencies associated with high morbidity and mortality rates. No single strategy has been sufficient to deal with the majority of situations. We aim to postulate a therapeutic algorithm for this complication based on 20 years of experience and also on data from published literature. We performed a retrospective clinical review of 44 patients treated for esophageal perforation at our hospital between January 1989 and May 2008. We reviewed the characteristics of these patients, including age, gender, accompanying diseases, etiology of perforation, diagnosis, location, time interval between perforation and diagnosis, treatment of the perforation, morbidity, hospital mortality, and duration of hospitalization. Perforation occurred in the cervical esophagus in 14 patients (31.8%), thoracic esophagus in 18 patients (40.9%), and abdominal esophagus in 12 patients (27.3%). Management of the esophageal perforation included primary closure in 23 patients (52.3%), resection in 7 patients (15.9%), and nonsurgical therapy in 14 patients (31.8%). In the surgically treated group, the mortality rate was 3 of 30 patients (10%), and 2 of 14 patients (14.3%) in the conservatively managed group. Four of the 14 nonsurgical patients were inserted with covered self-expandable stents. The specific treatment of an esophageal perforation should be selected according to each individual patient. To date, the most effective treatment would appear to be operative management. With improvements in endoscopic procedures, the morbidity and mortality rates of esophageal perforations are significantly decreased. We suggest that minimally invasive techniques for the repair of esophageal perforations will be very important in the future treatment of this condition.

Abstract
Ethyl pyruvate is a simple derivative in Ca(+2)- and K(+)-containing balanced salt solution of pyruvate to avoid the problems associated with the instability of pyruvate in solution. It has been shown to ameliorate the effects of ischemia-reperfusion (I/R) injury in many organs. It has also been shown that I/R injury delays the healing of colonic anastomosis. In this study, the effect of ethyl pyruvate on the healing of colon anastomosis and anastomotic strength after I/R injury was investigated. Anastomosis of the colon was performed in 32 adult male Wistar albino rats divided into 4 groups of 8 individuals: (1) sham-operated control group (group 1); (2) 30 minutes of intestinal I/R by superior mesenteric artery occlusion (group 2); (3) I/R+ ethyl pyruvate (group 3), ethyl pyruvate was administered as a 50-mg/kg/d single dose; and (4) I/R+ ethyl pyruvate (group 4), ethyl pyruvate administration was repeatedly (every 6 hours) at the same dose (50 mg/kg). On the fifth postoperative day, animals were killed. Perianastomotic tissue hydroxyproline contents and anastomotic bursting pressures were measured in all groups. When the anastomotic bursting pressures and tissue hydroxyproline contents were compared, it was found that they were decreased in group 2 when compared with groups 1, 3, and 4 (P < .05). Both anastomotic bursting pressure (P = .005) and hydroxyproline content (P < .001) levels were found to be significantly increased with ethyl pyruvate administration when compared with group 2. When ethyl pyruvate administration doses were compared, a significant difference was not observed (P > .05). Ethyl pyruvate significantly prevents the delaying effect of I/R injury on anastomotic strength and healing independent from doses of administration.

Abstract
Esophagogastric anastomotic leaks are the most feared surgical complications following resection of esophageal cancers. We aimed to develop a therapeutic algorithm for this complication characterized by high morbidity and mortality using our 20 years of experience and the published literature. A total of 354 patients who had undergone an esophagectomy and esophagogastric anastomosis due to esophageal carcinoma were evaluated retrospectively. The incidence for anastomotic leak was 15.5% (n = 90) in the cervical region and 4.2% (n = 264) in the thoracic region (mean: 7.1%). Cervical anastomotic leaks were detected after a mean period of 7.2 days following the procedure. Fourteen patients with cervical leaks were treated conservatively. Four out of 14 patients (28.6%) died due to sepsis and multi-organ failure related to fistula. Thoracic anastomotic leaks were detected after a mean period of 4.7 days following the procedure. Emergency reoperation, resection and reconstruction procedures were performed in one patient. Self-expanding metallic coated stents were placed at the anastomosis region in two patients. A more conservative approach was employed in other patients with thoracic anastomotic leaks. Six of them (46.2%) died due to fistula. General mortality rate was 37.0%, and the duration of hospitalization was 40.0 days for patients with anastomotic leaks. Cervical anastomotic leaks are more common than thoracic anastomotic leaks, but most of them are successfully treated with conservative approaches. Thoracic anastomotic leaks that in the past were related to high mortality rates despite conservative or surgical procedures might be successfully treated nowadays with the use of self-expanding metallic coated stents.

Abstract
PURPOSE Although one of the most common genetic polymorphisms that predispose to venous thromboembolism (VTE) is factor V 1691 G-A (Factor V Leiden; FVL), the effect of this polymorphism on the development of VTE in cancer patients is unclear. We have therefore performed a meta-analysis to estimate the risk of VTE associated with FVL among cancer patients. MATERIALS AND METHODS Relevant studies published before May 2006 were retrieved from Pubmed/Medline. We selected studies comparing the prevalence of FVL in cancer patients with VTE with cancer patients without VTE. Both fixed and random effect models were used. P-values and odds ratios (ORs) with 95% confidence intervals (95% CI) were calculated by Fisher's exact test. RESULTS Pooled results from 9 studies, comprising 397 cancer patients with VTE and 678 cancer patients without VTE revealed that the prevalence of FVL was higher among cancer patients with VTE (7.3%) than those without VTE (4.6%) (chi(2) = 34.633 > chi(2) (18; 0.05) =28.869) (p=0.013). It was also found that mean effect size of FVL was 0.22 (95% CI 0.051-0.4892). Using the homogeneity test, there was evidence of statistical heterogeneity (Q(hom)= 46.334> chi(2) (8; 0.05) =15.507) (p=0.0000). CONCLUSION Although the published studies were small and the meta-analysis demonstrated an association of FVL with cancer-related thrombosis, testing for FVL can be routinely used as part of clinical thrombophilia assessment in cancer patients from the regions with high incidence of FVL.

Abstract
Bronchogenic cysts are rare congenital cystic lesions mostly located in the middle and superior mediastinum. Esophageal bronchogenic cysts are extremely rare. We review here 23 cases reported in English in the literature to date of intramural esophageal bronchogenic cyst and their features, including our patient. Although they are extremely rare, intramural esophageal bronchogenic cysts should be kept in mind in the differential diagnosis of benign esophageal lesions. With accurate diagnosis and treatment the prognosis is excellent and serious complications may be prevented.

Abstract
Clinical hyperthyroidism is found in approximately 5% of women with a hydatidiform mole, as human chorionic gonadotropin secreted by molar tissue is structurally similar to thyroid-stimulating hormone. A hydatidiform mole occasionally presents with a co-existing viable fetus. Surgical evacuation may be indicated for significant hemorrhage or preeclampsia. Perioperative management in the presence of hyperthyroidism may be complicated by a thyroid storm. We report a case of total intravenous anesthesia with propofol and remifentanil, combined with an esmolol infusion, to control sympathetic hyperactivity during surgery.

Abstract
The presence of supernumerary breast (or polymastia) is not uncommon; however, reports of fibroadenoma in supernumerary breast tissue are rare. The present article reports a case of fibroadenoma developing in the supernumerary breast located below the normal left pectoral breast in a 26-year-old woman. Clinical and ultrasonographic examination of both pectoral breasts revealed no abnormalities but a mass was found in the third breast. The patient underwent resection of the supernumerary breast and the histopathological examination showed an intracanalicular type of fibroadenoma within the breast tissue.

Abstract
BACKGROUND Laser-assisted hair removal is a variably uncomfortable and painful procedure. OBJECTIVE The aim of this study was to investigate the efficacy of piroxicam gel on pain control and subsequent inflammation in Nd:YAG 1064 nm laser hair removal in women volunteers. METHODS Fifty women volunteers were enrolled in this prospective, randomised, placebo-controlled study over a 6-month period. Subjects were randomly assigned to receive piroxicam gel as Group P or saline as a control group. Topical analgesic and saline were applied to the treatment sites for 45 minutes. The pain scores (VAS) and side effects were recorded before the hair removal, during the hair removal, at the end of the hair removal, and after 1 hour, 2 hours and 24 hours after the hair removal. RESULTS Subject characteristics and treatment settings in Nd:YAG 1064 nm laser were similar in both groups. The pain scores (VAS) were significantly lower in the Group P than those of the control group during the hair removal (p < 0.001). Inflammatory side effects such as erythema, edema, and folliculitis, were more frequent in the control group than those of Group P during the procedure (p < 0.001). CONCLUSION This study showed that piroxicam gel provided adequate pain relief after Nd:YAG 1064 nm laser hair removal in women volunteers. Piroxicam gel was associated with lesser inflammatory side effects when compared to placebo because of its anti-inflammatory effect after the procedure.

Abstract
Tumour markers are used for diagnosis, staging, evaluation of response to treatment, prognosis and detection of recurrences in clinical oncology. In this study, we aim to investigate the levels of insulin-like growth factor (IGF)-I and IGF-binding protein (IGFBP)-III in cases with oesophageal carcinoma. We investigated their possible use as tumour markers and their relation to other tumour markers. Forty patients who were diagnosed as having oesophageal carcinoma by histopathological evaluation of endoscopic biopsies between January 2003 and July 2004 and 40 healthy people as the control group were included in the study. The serum levels of tumour markers including IGF-I, IGFBP-III, carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 were measured in both groups. Data were compared statistically, and the importance of IGF-I and IGFBP-III levels were investigated in cases with oesophageal carcinoma. IGF-I levels were significantly higher in patients with oesophageal carcinoma when compared with the control group (p < 0.05), whereas IGFBP-III levels were significantly lower (p < 0.05). The increase in CEA levels was not statistically significant when compared with the control group. The increase in CA 19-9 levels was statistically significant when compared with the control group (p < 0.05). No correlation was detected between levels of IGF-I and IGFBP-III and levels of CEA and CA 19-9. We suggest that the serum IGF-I level may be used as a tumour marker in oesophageal carcinoma. A low level of serum IGFBP-III is also significant in cases with oesophageal carcinoma. We believe that drugs which inhibit IGF-I function or which stimulate the function of IGFBP-III may open new horizons in extra-surgical modalities for the treatment of oesophageal cancer.

Abstract
Primary and metastatic malignancies of the sternum are uncommon. Secondary lesions to the sternum occur more commonly in patients with lung and breast cancer, and only a few cases of sternal metastasis arising from a follicular thyroid carcinoma have been reported in the literature. Rarely, metastases to the sternum present in the guise of primary sternal tumours may be treated surgically with that diagnosis in mind. We describe a case of a sternal mass treated by radical surgery, which ultimately proved to be a solitary metastasis from a follicular carcinoma of the thyroid, appearing 13 years after total thyroidectomy and radioactive iodine therapy. Late metastatic thyroid carcinoma to the sternum should be kept in mind in the differential diagnosis of sternal lesions. For patients with thyroid carcinoma and sternal metastasis, we recommend surgical resection of the metastasis, not only as a curative or palliative measure but also to maximise the effect of subsequent radioiodine treatment.

Abstract
PURPOSE The plasminogen activator inhibitor-1 (PAI-1) plays an important role in the development of tumor invasion and metastasis. The 4G allele of 4G/5G insertion / deletion polymorphism located in the promoter region 675 bp upstream from the transcription start sequence of PAI-1 gene is responsible for the higher plasma PAI-1 level. The aim of the present study was to evaluate the association between PAI-1 gene 4G / 5G polymorphism and breast cancer. MATERIALS AND METHODS Two groups were investigated: the first group(group 1)was composed of 34 patients with breast cancer, the second group (group 2) consisted of 90 unrelated healthy women without history of malignancy. Genomic DNA isolation was performed from peripheral venous blood by standard phenol-chloroform extraction and polymerase chain reaction of the PAI-1 4G/5G polymorphism was performed. RESULTS The prevalence of 4G/4G or 4G/5G genotype in group 1 and 2 was 97.1% and 78.8%, respectively. The distribution of the PAI-1 4G/5G genotypes was significantly different between the two groups (p<0.05). CONCLUSIONS We suggest that this polymorphism may contribute to an inherited predisposition to the development of breast cancer, however further studies with larger series from diverse ethnic populations are needed to confirm our results.

Abstract
BACKGROUND The aim of this study was to compare three patient-controlled analgesia (PCA) techniques for pain relief after acromioplasty. These techniques included use of subacromial ropivacaine, subacromial fentanyl or i.v. fentanyl. METHODS Forty-eight patients scheduled for open acromioplasty surgery were prospectively randomized to receive ropivacaine 0.2% (Group R) or fentanyl 4 microg ml(-1) (Group F) for subacromial analgesia, or fentanyl 4 microg ml(-1) (Group C) for i.v. analgesia. All patients received background infusion at a rate of 5 ml h(-1) plus a PCA bolus dose of 3 ml with a lockout time of 20 min. In addition, rescue analgesia with tramadol 50-100 mg i.v. was available on demand. Pain relief was regularly assessed using a visual analogue scale (0-10 cm) and side-effects were noted. RESULTS The postoperative pain scores at 2, 4, 6 and 12 h after the start of PCA were higher in Group F compared with Group R and Group C (P<0.001), However, the pain scores at the other time points were similar between the three groups. Pain scores, incremental dose requested and received, total volume of analgesic solution infused and rescue tramadol were similar between Group R and Group C. Specific side-effects were similar in the three groups. CONCLUSION The PCA techniques using subacromial ropivacaine or fentanyl i.v. provided similar and adequate pain relief and minimal side-effects after open acromioplasty surgery. The PCA using subacromial fentanyl was not as effective as either subacromial ropivacaine or i.v. fentanyl.
