Abstract
We report on a de novo desmoid tumor of the posterior mediastinum with transdiaphragmatic extension in a 40-year-old man. The tumor was inoperable because of its location and the invasion of adjacent structures. Although extremely rare, desmoid tumors of the posterior mediastinum should be considered in the differential diagnosis of posterior mediastinal masses.

Abstract
AIMS AND BACKGROUND This study was performed to determine the treatment outcomes and patterns of failure following external beam therapy in patients with pathological stage I-II endometrial carcinoma. STUDY DESIGN Eighty-three patients with stage I-II endometrial carcinoma surgically staged who were found to have high risk factors and who received postoperative radiation therapy are the subject of this report. High risk factors were: histologic grade II-III, depth of myometrial invasion (DMI) > or =1/2, stage II, poor prognostic histology (clear cell, papillary serous cell) and lymphovascular invasion. RESULTS Recurrences were observed in six patients. The recurrences were located in the vagina (1), lung (2), liver (1), and paraaortic lymph nodes (1). Five of the six recurrences were stage IC and II. The overall survival (OS), cause-specific survival (CSS) and disease-free survival (DFS) at five years were 82.9%, 85.0% and 81.3%, respectively. DMI, grade, age and cervical stromal invasion had a significant impact on CSS. CONCLUSION Adjuvant radiotherapy decreases the rate of relapse in pathologically staged high-risk stage I-II endometrial carcinoma patients. After reviewing the other studies on this subject we conclude that vaginal cuff brachytherapy alone could be used in stage IA grade III and stage IB grade I-II patients because the recurrence rate is low; pelvic radiotherapy + vaginal cuff brachytherapy should be used for stage IC-II disease. Distant metastases occurred in five of our patients and represent a significant type of failure.

Abstract
Aims and Background The orbit is an uncommon primary site for non-Hodgkin's lymphomas (NHL), and it accounts for less than 1% of all sites of primary presentations. We report the experience of the Department of Radiation Oncology at Ankara University Faculty of Medicine with radiation therapy in treatment of patients with stage I primary orbital NHL. Methods From February 1978 through August 1993, 14 patients with stage I primary orbital NHL were treated with radiation therapy. According to the Working Formulation classification, 8 patients had low-grade and 6 had intermediate-grade lymphomas. The most commonly used radiation therapy technique was a single anterior field with a Cobalt-60 unit, delivering 40 Gy in 2 Gy daily fractions. Two patients with intermediate-grade lymphomas received the CHOP regimen following radiation therapy. Results Follow-up ranged from 0.8 to 18.3 years (median, 10.3 years). Local control was achieved in all patients. Two patients with low-grade lymphomas relapsed locally and were successfully salvaged with radiation therapy. Three patients with intermediate-grade lymphomas failed systemically. Salvage therapy consisted of combination chemotherapy for 2 of them but was unsuccessful. Overall survival probabilities at 2, 5 and 10 years were 78.6%, 61.1% and 52.4%, respectively, for the entire group of 14 patients. Overall, cause-specific and disease-free survival probabilities were higher for patients with low-grade lymphomas than for those with intermediate-grade lymphomas (P = 0.03, P = 0.03 and P = 0.06, respectively). Cataracts were observed in 9 and lacrimal disorders in 4 patients. Conclusions The study suggests that among stage I primary orbital NHL, low-grade lymphomas could be treated with radiation therapy alone, whereas combination chemotherapy could accompany radiation therapy for intermediate-grade lymphomas.

Abstract
BACKGROUD Pancreatic cancer is the fourth leading cause of cancer death in the United States and leads to an estimated 227,000 deaths per year worldwide. Palliative and curative treatments are used for pancreatic cancer by laparoscopic or open techniques. The role of laparoscopy in pancreatic cancer is evaluated in this study. MATERIAL AND METHODS Electronic databases, such as PubMed/MEDLINE and Google Scholar were searched to identify reports of trials for laparoscopic pancreatic surgery. Articles written in English including the maximum number of patients published -between 2010 and 2014 were included. RESULTS Recent reports on laparoscopic surgery of the pancreas are encouraging and support the advantages of laparoscopy. Although large series have been reported for benign pancreatic -tumors treated with laparoscopic procedures, only limited data are available for malignant lesions. Most of these studies are retrospective, but the results encourage laparoscopic procedures. CONCLUSION Over the last decade laparoscopic pancreatic surgery has emerged as an alternative to open surgery with many advantages. There are limited data on about laparoscopic approach for the treatment of malignant lesions. The results are in favor of laparoscopy.

Abstract
AIM Food allergy is a common problem in children and adults. The aim of this study was to determine the frequency of cow's milk and egg allergy based on skin prick test and oral food challenge results METHODS We recruited 614 children aged 1 month-2 years in from different areas of Sanliurfa. An interview was conducted with each parents and family demographic, and prenatal-antenatal-postnatal information was recorded, then skin prick test was applied to the children for egg white, egg yolk and cow's milk. Cases that are required, sIgE levels for cow's milk, egg white and egg yolk were measured and food challenge tests were applied. RESULTS Cow's milk and egg allergy was determined in 1 case (0.16%) and 8 cases (1.30%) respectively from the results of the tests applied. Six cases (0.97%) were accepted as sensitive to egg white and egg yolk. Within the factors which were questioned, (only the egg allergy evaluation was made without the cow's milk allergy case) of those with parental consanguinity was determined at a statistically significantly high level (OR=5.8, 95% CI: 1.2-27.2, P=0.01). CONCLUSION The prevalence of cow's milk allergy in Sanliurfa is the lowest reported prevalence rate to date in children under 2 years of age. When infants develop a food allergy, this takes the form of egg allergy. Within the several factors evaluated to explain this situation, a significant relationship was determined only with parental consanguinity. However, as reported above, to date there is no genetic or epidemiological study to explain this situation.

Abstract
Central-line-associated bloodstream infection (CLABSI) is one of the most important problems in intensive care units (ICUs) worldwide. A bundle of CLABSI care measures was introduced at a 13-bed medical/surgical ICU in Kocaeli, Turkey in January 2010. Compliance rates with the bundle were measured at the beginning of the third quarter of 2010 until June 2013 and compared with CLABSI rates. During the post-intervention period, of 2196 ICU patients, 732 lines placed for 4366 line-days were monitored. Feedback to staff reinforced a culture of patient safety in the ICU. Infection rates remained zero for 38 months after the implementation. There was a strong negative correlation between bundle compliance rate and CLABSI rates. With the implementation of the central-line bundle of care, together with emphasis on high compliance with all its components and a culture of patient safety, it was possible to achieve and maintain a zero rate of CLABSI in this ICU.

Abstract
BACKGROUND Diabetes is the most common cause of renal failure. In patients with type I diabetes and renal failure,dialysis and insulin therapy can prevent a clinical context that causes rapid death, but they are insufficient to prevent longterm complications. Pancreas and islet cell transplantation inpatients with type I diabetes are the only curative treatment and have recently become more common. METHODS Between December 2006 and August 2010 a total of 10 patients underwent pancreas transplantation. The patient's data were analysed retrospectively. RESULTS 10 patients and their data were included in this study. Six patients were male and 4 patients were female. All patients are still alive, with functional grafts. CONCLUSIONS Pancreas transplantation is the most effective treatment for patients with type I DM. This paper discusses the feasibility of this process and presents the experience of Ankara University in pancreas transplantation.

Abstract
BACKGROUND single-port laparoscopic surgery has gained popularity over the last decade. This technique is used for several surgical procedures. This paper documents a new and cheaper access method known as "surgical glove port" or "homemade single-port", and describes our initial experience with 25 cases. METHOD Eleven cholecystectomies, eight totally extraperitoneal inguinal hernia repairs, three splenectomies, two gastric wedge resections, and one anti-reflux procedure were performed. RESULTS Twenty-four procedures out of twenty-five were completed without conversion to open or multiple port techniques. An individual patient who had both cholelithiasis and gastrointestinal stromal tumor underwent both cholecystectomy and gastric wedge resection in the same session with surgical glove port technique. In another case two additional 5-mm incisions were made for hemostasis. The additional operation was required and performed by using surgical glove port for a hiatal hernia repair case, because of postoperative hemorrhage. CONCLUSION Single-port laparoscopic surgery is an applicable technique for plenty of surgical procedures. Also, surgical glove port is a newer technique and some initial experience shave already published all over the world. Surgical glove port has advantages such as cost-effectiveness, easy and safe port implantation and specimen extraction. SGP can also be used for treating post-operative complications.

Abstract
AIM This study aimed to evaluate the neuropeptide Y values of patients with subacute sclerosing panencephalitis. MATERIALS AND METHODS The study comprised 38 patients diagnosed with subacute sclerosing panencephalitis at our clinic, who were being routinely followed-up, together with a control group of 36. Using the Risk and Haddad classification for clinical staging, 16 patients were determined as Stage II and 22 patients as Stage III. Neuropeptide Y values were measured by Enzyme Immunoassay methods. RESULTS The neuropeptide Y values of the all patients with subacute sclerosing panencephalitis were found to be significantly high compared to the control group (p<0.01). The neuropeptide Y values of the Stage III group were found to be significantly high compared to the Stage II and control groups (p<0.05). The neuropeptide Y values of the Stage II group were not determined to be significant compared to the control group (p≤0.05). CONCLUSIONS Neuropeptide Y can be considered a useful parameter to confirm diagnosis at advanced stages and to establish differences between stages in patients with subacute sclerosing panencephalitis.

Abstract
BACKGROUND/PURPOSE Surgical compresses used for retraction during major abdominal and pelvic procedures lead to postoperative adhesion formation resulting from damage to the visceral peritoneum. This study investigates whether polyvinyl chloride (PVC) covers cause less postsurgical adhesion and inflammation than surgical compresses in an animal model. METHODS Female Wistar albino rats (n = 160) were divided into three groups (compress, PVC cover and control), which were then divided into 16 subgroups (n = 10/group). All animals underwent midline laparotomy and cecal abrasion. A metal retractor, which applies a constant force, was then placed on the small intestine for 2 h. In the control group, no material was placed under the retractor, whereas a surgical compress or PVC cover was placed in the experimental animals. Full-thickness small intestinal biopsies were obtained and examined by light and electron microscopy. The following parameters were evaluated: congestion, mesothelial proliferation, leukocyte migration and collagenization. Adhesions were scored according to the Nair, Knightly and Mazuji scoring systems. RESULTS All inflammation scores were significantly higher in the compress group than in the other two groups. However, no significant difference was observed between the PVC cover and control groups. Adhesions were more frequent in the compress group than in the other two groups, regardless of the scoring system used. CONCLUSIONS Surgical compresses used in abdominal and pelvic surgeries cause inflammation and adhesion. Contrary to surgical compresses, PVC covers do not cause inflammation and adhesion, which may considerably reduce adhesion-related complications in abdominopelvic surgeries.

Abstract
BACKGROUND Organ transplantation from deceased donors is still far below the need. Because of this deficiency, liver transplantations are performed mostly from live donors in many transplant centers in our country. Living-donor liver transplantation (LDLT) has evolved dramatically over the past decade. The aim of this study was to present our clinical experience with living-donor hepatectomy. METHODS We retrospectively analyzed all patients who underwent donor hepatectomy between March 2000 and September 2010. We reviewed demographic data, operation type, operation and cold ischemia times, duration of hospital stay, and postoperative complications. RESULTS During the study period, 140 living donors underwent operations for liver transplantation. We performed 108 right hepatectomies, 17 left hepatectomies, and 15 left lateral hepatectomies. The mean age of the donors was 30.8 years. There was no operative or postoperative mortality. Overall morbidity rate was 13.57% (n = 19). Nine patients had biliary leakages, 4 biliomas; 2 urinary tract infections, and 1 each inferior vena caval injury, pneumonia, portal vein thrombosis, and acute tubular necrosis. Reoperation was not required in any of these patients. CONCLUSIONS Living-donor liver transplantation is a valuable alternative for patients awaiting a cadaver organ. Live-donor hepatectomy can be performed with low morbidity. The greatest disadvantage of this procedure is the risk of the surgical operation for the individual who will experience no medical benefit from this procedure.

Abstract
Pancreatic tail adenocarcinoma is both a diagnostic and therapeutic challenge. Despite technical and therapeutic advances, the prognosis remains dismal; the average survival time after diagnosis is characteristically only five to eight months. Both splenic infarction and abscess are very rare complications of pancreatic cancer. In this case of splenic infarction, the possible source of emboli should be carefully investigated. In addition, splenic abscess must be suspected in patients with splenic infarction, especially if the infectious signs persist despite appropriate treatment. Rapid diagnosis and treatment are essential as its course can prove fatal. The patient presented herein had a splenic infarct and abscess as complications of pancreatic tail carcinoma. The treatment of choice was splenectomy and distal pancreatectomy with resection of involved organs. The variability in clinical presentation and imaging studies warrants consideration of this entity in the differential diagnosis of many splenic and pancreatic lesions.

Abstract
The authors assessed the clinical efficacy, tolerability and safety of acitretin in a patient with ichthyosis. A newborn infant with ichthyosis who presented at birth with collodion baby appearance, was treated with acitretin. A moderate response to acitretin therapy (1 mg/kg/day) administered for 6 months was observed, with improvement in cutaneous lesions. Clinical improvement was achieved shortly after treatment. The treatment resulted in a satisfactory improvement in the skin condition of the case. The tolerance to the drug was good. Side effects were not observed. The oral acitretin treatment is efficient in severe congenital ichthyosis.

Abstract
Cystadenocarcinoma of the liver is a rare neoplasm that originates from hepatobiliary epithelium. Primary location of this tumor is generally intrahepatic and most cases are in the right hepatic lobe. Herein we present a case of intrahepatic cystadenocarcinoma in a 53-year-old man who had been followed up for 8 years as hydatic cyst disease of the liver. He was admitted to our hospital with jaundice and loss of appetite. Ultrasound and computed tomography showed a cystic lesion that looked like type II cyst hidatic. Thereafter magnetic resonance imaging revealed a cystic lesion associated with biliary tree. On diagnostic laparotomy peritoneal infiltrations were observed and pathologic examination revealed a biliary cystadenocarcinoma and peritonitis carcinomatosa was diagnosed. Unfortunately correct diagnosis was extremely late and no curative management was possible.

Abstract
AIM When there is excess inflammation, fibrosis and portal hypertension around gall bladder or in presence of Mirizzi syndrome, bile ducts and hepatic artery may be possibly damaged during dissection of Calot triangle. In this study, we examined safety and efficiency of partial cholecystectomy operation which we perform when dissection of Calot triangle is challenging. METHOD AND MATERIAL Eighteen patients who were undergone partial cholecystectomy in our clinic between 1996 and 2008 were retrospectively evaluated. Mean age of patients was 66 years (range: 55-88 years) and ratio of male/female was 2/1 (12 men, 6 women). Fourteen patients were undergone general anesthesia, whereas 4 patients were operated under epidural anesthesia. Partial cholecystectomies were performed by right subcostal incision in 16 patients and by right paramedian incision in 2 patients. RESULTS No intra-operative or early post-operative mortality was found among patients. Post-operative subhepatic abscess occurred in one patient (5.5%) and superficial wound site infection occurred in 4 patients (22,2%). Controlled bile fistula occurred in early post-operative period in two patients (11.1%) and fistula spontaneously closed without requiring additional surgical procedure. Escherichia coli were most common microorganism found in bile culture. Mean hospitalization period of patients was 8 days (range: 15-14 days) and mean follow-up period was 80 months (8-150 months). During follow up, hepatobiliary ultrasonography could be re-performed in 8 patients and no new stone formation was observed. In 7 patients, it was understood verbally that no postoperative gastrointestinal symptoms were present. CONCLUSION Where dissection of Calot triangle is changeling, partial cholecystectomy can be safely and efficiently performed.

Abstract
Dandy-Walker malformation is an anomaly characterized by dysgenesis of the foramina of Magendie and Lushka in the upper 4(th) ventricle, hypoplasia of the cerebellar vermis and agenesis of the corpus callosum. Encephalocele is diagnosed from the calvarium defect, cerebrospinal fluid (CSF) and herniation of the meninges. It is the rarest neural tube defect. A 7 x 9 cm encephalocele was found on physical examination of a 6-day old baby boy patient. From cranial magnetic resonance, it was seen that the posterior fossa was enlarged with cysts and there was agenesis of the vermis. A connection was established between the ventricle and the development of cysts on the posterior fossa. These findings were evaluated as significant from the aspect of Dandy-Walker malformation. The extension of the bone defect in the left occipital area towards the posterior, and the cranio-caudal diameter reaching 9 cm was seen to be in accordance with encephalocele. It is rare for Dandy-Walker syndrome to occur together with occipital encephalocele. The authors present a case of Dandy-Walker syndrome together with occipital encephalocele.

Abstract
PURPOSE To report herein our results of tension-free repair of large incisional hernia with polypropylene mesh using a modification of the method that was described by Usher. METHOD Two hundred ninety-one patients who were operated on between January 1994 and December 2004 were studied. Two hundred thirty-two patients were female (79.7%), and 59 were male (20.3%). The average follow-up period was 55 months. The patients were evaluated for infection, recurrences, hematoma and seroma formation, sinuses and enterocutaneous fistula formation. RESULTS Infection was observed in eight patients (2.7%). Graft removal due to infection was encountered only in two patients (0.6%). Recurrence was observed in six patients (2.1%). Two patients (0.6%) developed hematoma while another two developed seroma. No patient developed enterocutaneous fistula. CONCLUSION By using our modified technique we can decrease the expected complications after tension-free repair of large incisional hernias.

Abstract
This study investigated the factors influencing the effectiveness of 7.5% polyvidone iodine as a surgical antiseptic. The study involved 100 operating staff (75 doctors and 25 nurses) from hospital surgical teams. Fingertips of both hands of the subjects were pressed on to agar culture before and after washing and after completion of surgery. Handwashing lasting for more than 3 min led to a significant decrease in the number of colonies compared with handwashing lasting for less than 3 min. Moreover, the number of colonies was significantly higher when surgery lasted for longer than 95 min. However, the handwashing style (with or without brushing) was not found to have a significant effect on the outcome of the disinfection procedure in terms of bacterial colonization. Subjects who had colonization of their hands after surgery were found to have significantly higher colony counts before handwashing compared with those who did not have any colonization on their hands after surgery. The results of this study revealed that in order to attain effective disinfection with polyvidone iodine, the duration of handwashing should be at least 3 min. The risk of recolonization increases when the duration of surgery exceeds 95 min.

Abstract
This study was carried out to determine the prevalence and distribution of tropical theileriosis in cattle in eastern Turkey by microscopical, serological and molecular methods. A total of 1561 whole blood, 1505 serum and 1483 blood smear samples were collected from cattle of various breeds and ages in 11 towns of Eastern Turkey. Theileria annulata piroplasm DNA extracted from cattle blood was amplified by polymerase chain reaction (PCR) using species-specific primers. Serum antibodies against T. annulata were investigated by indirect fluorescence antibody test (IFAT). Blood smears were examined for Theileria piroplasms by microscopical examination (ME). In the examination of DNA extracted from 1561 blood samples, an amplicon with the size of 721bp was obtained in 37.8% (590/1561) of these samples. Serum antibodies against T. annulata and piroplasm of Theileria spp. were detected in 34.9% (526/1505) and 19.7% (293/1483) of the samples, respectively. The differences between ME and PCR results and between ME and IFAT results were statistically significant (P < 0.05). In contrast, there was no significant difference between the PCR and IFAT results. A total of 179 ticks (136 female; 43 male) belonging to Hyalomma spp. were collected from cattle from three towns. Ticks were identified to be Hyalomma anatolicum anatolicum on the basis of morphological features.

Abstract
An epidemiological survey for Theileria annulata infection was conducted in 12 selected villages around Ankara in Central Anatolia, Turkey, during the period April 1990 to January 1993. During the survey, 198 cattle of 30 local breeds, 84 Holstein-Friesian x local breeds and 84 Holstein-Friesian breed were examined for antibodies to T. annulata and the presence of the vector ticks. Four species of Hyalomma ticks were identified: Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavtum, Hyalomma detritum and Hyalomma marginatum marginatum. Salivary gland staining indicated that infected adult ticks of all four species were present and, therefore, were implicated in the transmission of tropical theileriosis in the field. Generally, the Hyalomma infestation rate was low, with the heaviest infestations occurring on the older animals. Young adults and calves had very low infestation rates. Most ticks seen on cattle were adults, very few nymphs were found. The blood smear and serological examination of the 198 cattle conducted in March, before the start of the first disease season, showed that the prevalence of piroplasmosis was 11.1% (22 out of 198) and the seroprevalence of T. annulata was 10.6% (21 out of 198). Forty-three animals were then excluded from the study because they were seropositive and/or harboured piroplasms. Ninety-two seronegative animals showed piroplasmosis (92 out of 155) and 34 seronegative animals became seropositive for T. annulata (34 out of 155) during the three disease seasons. One animal became clinically ill with tropical theileriosis and required treatment. The incidence of cattle showing piroplasmosis and disease in the total study sample was 50.7% and 0.5% per disease season, respectively. The seroconversion rate of new infection with T. annulata in the total study was 14.3% per animal season. The number of cattle showing piroplasmosis was much greater than the number of seropositive cattle, which may indicate the presence of another species of Theileria. The two different management systems encountered in the study were considered to have influenced the tick infestation levels.

Abstract
Wound infection after a surgical procedure is one of the main problems affecting the success of an operation. The prepuce is used in hypospadias surgery and in tissue defects in reconstructive surgery. The objective of this study is to determine the efficacy of povidone-iodine and surgical soap in preputial skin preparation. Ninety-four healthy children were divided into three groups. After obtaining preputial skin swabs, an application of povidone-iodine 10% was made and skin swabs were obtained after two and five minutes in group 1. An additional application of povidone-iodine after two minutes was made in group 2 and swabs taken. Group 3 received a local scrub with surgical soap and an application of povidone-iodine. Results showed that, despite painting with povidone-iodine and/or local cleaning with surgical soap, it is not possible totally to eradicate the micro-organisms in the prepuce. Surgical soap decreases the colony count, which can lead to increased effectiveness of povidone-iodine after painting. We recommend preoperative local cleaning with surgical soap before surgical painting.

Abstract
In this comparative study unfed nymphs of four Hyalomma tick species (Hyalomma anatolicum anatolicum, Hyalomma anatolicum excavatum, Hyalomma detritum and Hyalomma marginatum marginatum) were allowed to engorge on calves experimentally infected with Theileria annulata. The infection prevalence in the salivary glands of the adult female and male ticks of each Hyalomma species used in the study were assessed. The infection prevalence with T. annulata was high and did not vary markedly in the four Hyalomma tick species. The mean number of infected acini per tick in female and male ticks was different with female ticks having higher numbers of infected acini than the male ticks. The sex difference was more significant between H.a. anatolicum and H.a. excavatum than between H. detritum and H.m. marginatum. This study clarifies the roles of four Hyalomma tick species, and their sex, in the development of T. annulata.

Abstract
PURPOSE The present study reviews the experience in treatment of 447 patients with nasopharyngeal carcinomas, analyzing patient, tumor and treatment characteristics determining outcome. MATERIALS AND METHODS There were 322 males and 125 females, their ages ranging from 7 to 85 years (median, 45 years). Two-hundred and seventy-two patients had World Health Organization (WHO) type 3 carcinomas, 123 patients had T4 tumors and 320 patients had metastatic cervical lymph nodes. Three-hundred and eight patients were treated with radiation therapy alone and 139 patients with chemotherapy in combination with radiation therapy. Cumulative radiation dose to primary tumor ranged from 50 to 76Gy (median, 70Gy) and radiation dose to metastatic cervical lymph nodes ranged from 46 to 74Gy (median, 66Gy). RESULTS Follow-up ranged from 0.1 to 19.5 years (mean, 7.6 years). Local complete response was achieved in 357 patients. In multivariate analysis, T-classification, cumulative radiation dose to primary tumor and treatment with chemotherapy in combination with radiation therapy predicted local response. Nodal complete response was achieved in 272 patients. In multivariate analysis, N-classification and radiation dose to metastatic cervical lymph nodes predicted nodal response. Local failure was observed in 70 patients, nodal failure in 35 patients and systemic failure in 114 patients. Overall survival, disease-free survival and disease-specific survival were 33, 32 and 37%, respectively, at 10 years. In multivariate analysis, age, T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted overall survival whereas T-classification, N-classification, radiation dose and treatment with chemotherapy in combination with radiation therapy predicted both disease-free survival and disease-specific survival. CONCLUSIONS Radiation therapy alone appears to be an adequate and viable treatment for patients with early-stage nasopharyngeal carcinomas, whereas treatment with chemotherapy in combination with radiation therapy appears to improve outcome for patients with advanced-stage nasopharyngeal carcinomas.

Abstract
Radiation therapy in combination with chemotherapy in the management of locoregionally advanced nasopharyngeal carcinomas is evaluated in an attempt to improve locoregional response, reduce locoregional failure and reduce systemic failure. The current study was designed to investigate radiation therapy and concurrent cisplatin in this context. From 1992 through 1997, 70 patients with locoregionally advanced nasopharyngeal carcinomas were treated with radiation therapy and concurrent cisplatin. External beam radiation dose was 60 Gy for T1, T2 and T3 tumors, 70 Gy for T4 tumors and 70 Gy for metastatic cervical lymph nodes. An intracavitary brachytherapy boost (10 Gy) was applied for T1, T2 and T3 tumors. Cisplatin (30 mg/m2) was administered weekly during external beam radiation therapy. Locoregional complete response was achieved in 63 patients, locoregional failure was observed in 4 patients and systemic failure was observed in 15. N-stage predicted systemic failure. Overall survival, locoregional failure-free survival and systemic failure-free survival were 63%, 79% and 75%, respectively, at three years. Grade 3 acute skin toxicity was observed in 2 patients, Grade 3 acute mucous membrane toxicity was observed in 6 and Grade 3 acute hematological toxicity was observed in 2 patients. Despite improved locoregional response, reduced locoregional failure and improved survival with radiation therapy and concurrent cisplatin, systemic failure remains prevalent for locoregionally advanced nasopharyngeal carcinomas.

Abstract
Forty-four patients with head and neck malignancies were included in a prospective, randomized, double-blind, placebo-controlled study for evaluation of sucralfate in prevention of oral mucositis induced by radiation therapy. Patients were randomized to receive oral suspensions of either sucralfate (n = 23) or placebo (n = 21) in six daily doses of 1 g. The primary tumors were treated with portals covering at least one-third of the oral mucosa to a minimum dose of 60 Gy. Drug therapy was not associated with significant adverse effects and compliance was satisfactory. Daily inspection of the oral mucosa and questionnaires for oral mucositis-related items demonstrated reduction in oral mucositis scores and oral pain scores and biopsies obtained from the buccal mucosa demonstrated reduction in evidence of altered vascular calibration, altered vascular permeability and leukocyte emigration with sucralfate. Clinical and histopathological demonstration of reduction in oral mucositis with sucralfate suggests that sucralfate might be recommended in the prevention of oral mucositis induced by radiation therapy in patients with head and neck malignancies.

Abstract
Twenty-one patients with recurrent carcinomas of the head and neck with metastatic cervical lymph nodes were treated with radiation therapy, cisplatin and hyperthermia in combination, in an attempt to investigate any potential contribution in terms of safety, response, duration of palliation and quality of life. Patients not initially treated with radiation therapy were treated with a median dose of 70 Gy and patients initially treated with radiation therapy with a median dose of 30Gy. The median number of weekly cisplatin courses was five and the median number of twice weekly local external ultrasound hyperthermia sessions was five. Average T90, Average T50 and Average T10 were 39.9 +/- 1.2 degrees C, 42.4 +/- 1.3 degrees C and 44.5 +/- 0.8 degrees C, respectively, and Average CEM 43 degrees C T90, Average CEM 43 degrees C T50 and Average CEM 43 degrees C T10 were 7.8+/-9.6min, 22.6 +/- 18.8min and 39.3 +/- 25.1min, respectively. Mean follow-up was 1 year. Nodal complete response was achieved in eight patients and palliation of presenting symptoms in 19. Overall survival was 39% at 1 year. Grade 3 acute skin toxicity was observed in one patient and Grade 3 acute haematological toxicity in one. Radiation therapy, cisplatin and hyperthermia in combination appear to be safe and might improve response, prolong duration of palliation and reinstate quality of life in patients with recurrent carcinomas of the head and neck with metastatic cervical lymph nodes.

Abstract
PURPOSE This study investigated the prognostic significance of age, stage, tumor size, pelvic lymph node metastasis (PLM), surgical margin invasion, overall radiotherapy time (ORT), and interval between radiotherapy and surgery (IRS) in stage IB-IIA cervical carcinoma. METHOD AND MATERIALS 100 patients treated with radical hysterectomy and postoperative radiotherapy were evaluated retrospectively. RESULTS The 5-yr overall survival (OS), disease-free survival (DFS), and pelvic control rate (PC) were 83.6%, 82.8%, and 91.8%, respectively. PLM (p=0.008), IRS (p=0.01), ORT (p=0.007), and tumor size (p=0.028) were found to be significant on PC. PLM (p=0.04), ORT (p=0.04), and IRS (p=0.001) were significant on OS. PLM was significant (p=0.04) and IRS was marginally significant (p=0.06) on DFS. After multivariate analysis, PLM was significant on OS, DFS and PC. Recurrences were seen in 14 patients. CONCLUSION According to this study PLM, IRS, and ORT are the most important prognostic factors. Recurrences outside the radiation volume leads to treatment failure.

Abstract
Patients with inoperable carcinoma of the cervix treated with external plus high dose rate brachytherapy (HDRB), between 1988 and 1995 were evaluated retrospectively. According to stage, 5 year survival rates were 67.3% in stage IIb and 52.6% in stage III (P = 0001) and disease free survival (DFS) rates were 54.0% in stage IIb and 43.9% in stage III (P = 0.01). The following parameters were studied: age; stage; external beam dose; brachytherapy dose; total dose to point A; tumor mass; tumor response rate; bilateral or unilateral invasion of parametria in stage IIb; and bilateral or unilateral invasion of pelvic wall in stage IIIb; and the existence of hydronephrosis. The only significant parameter of 5 year survival and local control was tumor mass (P = 0.003).

Abstract
Fifty-three patients with carcinomas of the head and neck with N2 or N3 metastatic cervical lymph nodes were treated with radiation therapy (median, 70 Gy), cisplatin (median, 6 weekly courses) and hyperthermia (median, 6 twice weekly sessions). Local complete response was achieved in 82% and nodal complete response in 85% of patients. Overall survival was 51% and disease-free survival was 54% at 2 years. Toxicity was acceptable. Radiation therapy, cisplatin and hyperthermia in combination prove to be effective and safe in management of these patients.

Abstract
BACKGROUND This study reviews the authors' experience from 1979 through 1996 in the management and outcome of 56 patients with nasopharyngeal carcinoma who were under 20 years of age. PROCEDURE There were 33 males and 23 females, their ages ranging from 7 to 19 years (median: 16 years). Forty patients had World Health Organization type III carcinomas, 16 had T4 tumors, 41 had metastatic cervical lymph nodes, and 50 were at stage III or stage IV. Thirty-two patients were treated with radiation therapy alone and 24 with the addition of chemotherapy. Cumulative radiation dose to the primary tumor ranged from 18 to 70 Gy (median: 66 Gy) and radiation dose to metastatic cervical lymph nodes ranged from 18 to 70 Gy (median: 66 Gy). RESULTS Follow-up ranged from 0.1 to 16.8 years (mean: 9 years). Locoregional tumoral complete response was achieved in 49 patients. Locoregional tumoral failure was observed in 12 patients and systemic failure in 11. Overall, locoregional failure-free, metastases-free, and disease-free survival rates at 5 years were 49%, 62%, 79%, and 47%, respectively, for the entire group of patients, 42%, 61%, 72%, and 42%, respectively, for patients treated with radiation therapy alone, and 58%, 63%, 87%, and 54%, respectively, for patients treated with the addition of chemotherapy. Advanced T-stage and lower radiation doses worsened locoregional failure-free survival, whereas advanced N-stage and exclusion of chemotherapy worsened metastases-free survival. CONCLUSIONS In children and adolescents with nasopharyngeal carcinoma, radiation therapy alone results in an improved locoregional tumoral response rate and a reduced locoregional tumoral failure rate at higher radiation doses, while the addition of chemotherapy results in a reduced systemic failure rate.

Abstract
BACKGROUND AND PURPOSE Optic pathway and chiasmatic-hypothalamic gliomas are rare childhood tumors. This study presents the experience in management of these tumors with radiation therapy. MATERIALS AND METHODS Thirty-three children with the diagnosis of optic pathway and chiasmatic-hypothalamic gliomas were treated with radiation therapy from 1973 through 1994 in the Department of Radiation Oncology at Ankara University Faculty of Medicine. Twenty-four children had optic pathway gliomas and nine had chiasmatic-hypothalamic gliomas. Evidence of neurofibromatosis was present in six children. Subtotal resection was performed in 22 children and a biopsy in seven. The most common prescription for total tumor dose was 50 Gy, delivered in 2 Gy daily fractions. Follow-up ranged from 0.5 to 16.1 years (mean, 13.6 years). RESULTS Overall, progression-free and cause-specific survival probabilities for the entire group were 93%, 82% and 93%, respectively, at 5 years and 79%, 77% and 88%, respectively, at 10 years. Differences in overall, progression-free and cause-specific survival probabilities between optic pathway and chiasmatic-hypothalamic gliomas were not statistically significant. Absence of evidence of neurofibromatosis correlated with significantly better progression-free and cause-specific survival probabilities. CONCLUSION Radiation therapy is effective in stabilization or improvement of vision and prevention of tumor progression in both optic pathway and chiasmatic-hypothalamic gliomas.

Abstract
Medical reports of 1293 patients with squamous cell carcinoma (SCC) of the head and neck were retrospectively evaluated. The patients were classified according to their age, sex, primary tumour localization and tumoral stage. There were 1181 males (91.3 per cent) and 112 females (8.7 per cent), with a male to female ratio of 10.5:1. The peak incidences for all primary tumour localizations were observed in the fifth decade. Most common primary tumour localizations were the larynx (71.1 per cent), the nasopharynx (10.1 per cent) and the oral cavity (8.8 per cent). Of all patients in whom staging was complete, 43.1 per cent presented at early and 56.9 per cent at advanced stages. The proportion of patients presenting with metastatic neck nodes was 34.4 per cent and the incidence of metastatic neck nodes increased with increasing T stage. The supraglottic region was the most common primary site among all laryngeal SCC, with a supraglottic to glottic SCC ratio of 1.5:1. Glottic SCC presented at earlier stages compared to supraglottic SCC. The incidence of nodal metastases increased with increasing T stage for SCC of the larynx, the oral cavity and the oropharynx.

Abstract
A serological survey using Indirect Fluorescent Antibody Test (IFAT) for Babesia ovis infection of sheep has been carried out in different geographical regions of Turkey. The results indicated that 71.6% of 141 sheep in Black Sea region, 70.9% of 93 sheep in central Anatolia, 80.2% of 96 sheep in Aegean region and 55.7% of 122 sheep in eastern Anatolia were seropositive. This means that B. ovis infection is endemic throughout Turkey. In addition, occurrence of B. ovis, B. motasi, Theileria hirci, T. recondita and Anaplasma ovis infections in sheep and goats has been reported previously in Turkey as well. However further studies are needed to obtain more information about the agents to keep the infection under control.

Abstract
From September 1989 to February 1993, 11 patients with localized adenocarcinoma of the prostate were treated with pelvic external-beam radiation therapy followed by high dose rate (HDR) transurethral brachytherapy as a boost dose. External-beam radiation therapy was administered through opposed pelvic fields using a 60Co teletherapy unit to a tumor dose of 46-50 Gy in 23-25 fractions and followed by three fractions of transurethral brachytherapy, delivered using a 60Co HDR remote afterloading equipment. The treatment time was calculated using the prostatic capsule as the reference point. The dose calculated to be delivered to the capsule was 5 Gy/fraction, making a total of 15 Gy. The follow-up period ranged from 11 to 65 months, with a median follow-up time of 30 months. Local control was achieved in all patients. The prostate-specific antigen levels were normalized within 3 months of radiotherapy in 9 patients and within 3-6 months in the remaining 2. Transurethral brachytherapy appears to be a simple and feasible form of brachytherapy. Preliminary local control and radiotherapy-related morbidity rates are comparable to those of other forms of brachytherapy. Further follow-up is required for assessment of long-term local control and delayed radiotherapy-related morbidity.
