Abstract
OBJECTIVE In this study we aimed to define clinical, radiologic and pathological specialties of patients who applied to General Surgery Department of Atatürk University Medical Faculty with granulomatous mastitis and show medical and surgical treatment results. With the help of this study we will be able to make our own clinical algorithm for diagnosis and treatment. MATERIALS AND METHODS We searched retrospectively addresses, phone numbers and clinical files of 93 patients whom diagnosed granulomatous mastitis between a decade of January 2001 - December 2010. We noted demographic specialties, ages, gender, medical family history, main complaints, physical findings, radiological and laboratory findings, medical treatments, postoperative complications and surgical procedures if they were operated; morbidity, recurrence and success ratios, complications after treatment for patients discussed above. RESULTS In this study we evaluated 93 patients, 91 females and 2 males, with granulomatous mastitis retrospectively who applied to General Surgery Department of Atatürk University Medical Faculty between January 2001 and December 2010. Mean age was 34.4 years. The diagnosis was confirmed by histopathologic examination of the lesions. Seventy three patients had idiopathic granulomatous lobular mastitis and 20 patients had specific granulomatous mastitis IGM (18 tuberculosis mastitis, 1 alveolar echinococcosis and 1 silk reaction). All the patients had surgical debridement or antibiotic, and anti-inflammatory treatment with results bad clinical response before applied our clinic. CONCLUSION Empiric antibiotic therapy and drainage of the breast lesions are not enough for complete remission of idiopathic granulomatous mastitis. The lesion must be excised completely. In selected patients, corticosteroid therapy can be useful. In the patients with tuberculous mastitis, abscess drainage and antituberculous therapy can be useful, but wide excision must be chosen for the patients with recurrent disease.

Abstract
BACKGROUND Cardiac arrest is a major life-threatening complication of subarachnoid hemorrhage (SAH). Although medullary cardiocirculatuar center injury and central sympathetic overactivity have been suspected of initiating coronary artery spasm-induced cardiac arrest, we aimed to elucidate the effects of vagal ischemia at the brainstem on coronary vasospasm and sudden death in SAH. METHODS Twenty-six rabbits were randomly divided into 3 groups. Control (n = 5); SHAM (n = 8), and SAH group (n = 13). Experimental SAH was applied by injecting homologous blood into the cisterna magna, and the SHAM group was injected with isotonic saline solution also in the cisterna magna., Twenty-one days after the injection, histopathologic changes of the neuron density of nodose ganglia, the vasospasm index values of the coronary arteries, and the electrocardiographic events were analyzed. RESULTS Increased vasospasm index of the coronary arteries and degenerated neuron density of nodose ganglion were significantly different between animals with SAH, control, and SHAM groups (P < 0.005). If neurons of the nodose ganglia are lesioned due to ischemic insult during SAH, the heart rhythm regulation by vagus afferent reflexes is disturbed. CONCLUSIONS We found that there is causal relationship between nodose ganglion degeneration and coronary vasospasm. Our finding could be the reason that many cardiac events occur in patients with SAH. Vagal pathway paralysis induced by indirect sympathetic overactivity may trigger coronary vasospasm and heart rhythm disturbances. Our findings will aid in the planning of future experimental studies and in determining the clinical relevance of such studies.

Abstract
BACKGROUND Breast cancer is the second most frequent cancer in the world. Although it is widely accepted that the etiology of breast cancer includes both genetic and environmental factors, the molecular mechanism of its development and progression remains poorly understood, and thus far, no specific signature of breast cancer gene expression has been reported to allow for patient-tailored therapy strategies. Hence, it is of great clinical value to further understand the molecular mechanisms underlying the progression of breast cancer and to identify effective early markers for the diagnosis and prognosis of the disease as well as novel therapeutic targets. MATERIALS AND METHODS This study was conducted on a total of 90 paraffin-embedded breast tumor samples. Immunohistochemical stains for astrocyte elevated gene-1 (AEG-1), basic-fibroblast growth factor (b-FGF), beta-catenin, Ki-67, tumor necrosis factor-α (TNF-α) were performed on tissue microarray using standard procedures. Each patient age, grade, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) status, size, lymphovascular invasion, metastasis of lymph node (LNM), nipple and ductal hyperplasia areas were assessed. RESULTS We observed significant relationship between the age and LNM or FGF (P = 0.018, 0.035, respectively). The relationship between histological and nuclear grade, LNM, ER, PR, HER-2 and prognostic parameters was evaluated in cases of ductal carcinomas (DC). There was a significant positive correlation between TNF-α, size, LNM (P ≤ 0.0001, 0.002, 0.005). We found that significant relationship between AEG-1 and TNF-α. There was a significant positive correlation between FGF and Ki-67 and negative correlation AEG-1. Although, FGF, TNF-α, AEG-1 staining in DC were observed higher than ductal intraepithelial neoplasms, this observation could not statistically (P ≥ 0.05). CONCLUSIONS The present work aims to investigate the relationship between the expression of AEG-1, b-FGF, beta-catenin, Ki-67, TNF-α other prognostic parameters in DC and ductal intraepithelial neoplasm. We found a relationship between these factors.

Abstract
Malignant glioma development after trauma is a rare occurrence. We report a glioblastoma multiforme case that developed after a depressed skull fracture. A 65-year-old man was admitted because of right sided hemiplegia, epilepsy and changes in consciousness due to a malignant glial tumor. He had been operated on for a left calvarial depression fracture caused by cerebral laceration thirty-five years before. Radiologic imaging revealed a large contrast-enhanced mass lesion at the left frontotemporoparietal junction under the depression site. The patient underwent urgent surgery, and radical excision of the mass was achieved. The histopathologic diagnosis was a high-grade glial tumor. Although the possibility of a pre-existing tumor rather than a trauma-induced tumor is very high, the presented case suggests that traumatic cerebral lesions may also be a predisposing factor for the development of malignant glial tumors.

Abstract
Malignant melanoma is a malignancy of pigment-producing cells (melanocytes) located predominantly in the skin. Nodal metastases are an adverse prognostic factor compromising long term patient survival. Therefore, accurate detection of regional nodal metastases is required for optimization of treatment. Computed tomography (CT) and magnetic resonance imaging (MRI) remain the primary imaging modalities for regional staging of malignant melanoma. However, both modalities rely on size-related and morphological criteria to differentiate between benign and malignant lymph nodes, decreasing the sensitivity for detection of small metastases. Surgery is the primary mode of therapy for localized cutaneous melanoma. Patients should be followed up for metastases after surgical removal. We report here a case of inguinal lymph node enlargement with a genital vesicular lesion with a history of surgery for malignant melanoma on her thigh two years ago. CT and diffusion weighted-MRI (DW-MRI) were applied for the lymph node identification. DW-MRI revealed malignant lymph nodes due to malignant melanoma metastases correlation with pathological findings.

Abstract
AIM To determine the utility of mast cell numbers and microvascular density (MVD) in evaluating acinar type of prostatic adenocarcinoma (PCa), and to ascertain a relationship between the number of mast cells with prognostic parameters (larger tumor volume, high Gleason score, lymphovascular, perineural, seminal vesicles invasion, metastatic lymph node). METHODS The study comprised 97 radical prostatectomy specimens. The paraffin sections were stained with anti-CD31, anti- CD34 and Toluidine Blue. The numbers of positive staining of cells and microvessels in 10 high-power fields were counted systematically. RESULTS A statistically significant relationship was found between MVDn and number of MC (r=0.218 and p=0. 032). There was no correlation between age and MC and MVD (p=0.406 and p=0.671, respectively). CONCLUSION A correlation between mast cell number and microvascular density cannot depend on tumor angiogenesis or this relationship can be an independent parameter. More comprehensive studies could reveal relationship with prognostic parameters.

Abstract
BACKGROUND Acute hydrocephalus (ventricular enlargement within 72 hours) is a common complication in patients with aneurysmal subarachnoid hemorrhage (SAH). Cerebrospinal fluid (CSF) secretion may be increased in the early phases of SAH, but it has not been proved definitively. We studied the histologic features of choroid plexus (CP) in the early and late phases of SAH. METHODS This study was conducted on 20 rabbits, with 5 rabbits in the control group, 5 rabbits in the sham group, and 10 rabbits in the SAH group. In the SAH group, five of the animals were decapitated after 2 days of cisternal blood injections, and the other five animals were decapitated after 14 days of injections. The CP of lateral ventricles were obtained from coronary sections of brains at the level of the temporal horns of the lateral ventricles. Sections were stained with hematoxylin and eosin and Masson trichrome for SAH-related damage and examined stereologically to discern water-filled vesicles, which were counted. Sections were compared statistically. RESULTS The mean numbers of water vesicles were different after SAH between the early decapitated group (group III) and the late decapitated group (group IV). The mean numbers of water vesicles were 2.80 (± 0.05) in the control group (group I), 2.76 (± 0.02) in the sham group (group II), 14.68 (± 0.06) in the early decapitated group (group III), and 4.78 (± 0.13) in the late decapitated group (group IV). Total number of fluid-filled vesicles of CP was also assessed stereologically; the total numbers were 840 (± 16) in group I, 828 (± 7) in group II, 4404 (± 19) in group III, and 1434 (± 41) in group IV. The numbers of water-filled cisterns were significantly increased in the early phases of SAH (P < 0.05). CONCLUSIONS In SAH with aneurysm rupture, increased CSF secretion seems to be triggered by hemorrhage in the early phase, but it is not possible in the late phase because of CP degeneration. In the early phase of hemorrhage, CSF secretion may be stimulated by the irritant receptor glossopharyngeal and vagal nerve endings, which innervate the healthy CP epithelium and arteries. Our findings may be accepted as being causative. It is likewise possible that CSF blockage per se leads to hydrocephalus, and the morphologic changes are sequelae that occur later in the course of disease. This is the first study to show the water vesicles of CP as a causative factor in the development of acute hydrocephalus after SAH.

Abstract
AIM We examined whether vasospasm of choroidal arteries (ChAs) may be resulted in ischemic injury in choroid plexus (CP) after subarachnoid hemorrhage (SAH). MATERIAL AND METHODS This study has been conducted on 30 rabbits. Eight, fourteen and eight of them were used as control, SAH and SHAM groups, respectively. The volumes of choroidal arteries were examined and measured by using the micrometric microscope barr. Ischemic morphological changes of the choroid plexus cells and villus were examined as follows: cellular shrinkage (1 point), cytoplasmic condensation (2 points), angulation (3 points) and villus desquamation (4 points) were considered as 1st, 2nd, 3rd, 4th degree downward choroid plexus degeneration criteria. Degeneration scores of 1 to 4 criteria were calculated by summing the exacerbated ones with the existing one. RESULTS Choroidal artery diameter&volume, and CP degeneration scores in three groups were evaluated: The mean volumes were 1.080 ± 0.650 mm³, 0.907 ± 0.330 mm³, 0.480 ± 0.175 mm³ and the degeneration scores of choroidal plexuses were scored as 0 and 1- 1, and 4- 3 and 10 in the control, SHAM and SAH groups respectively. A significant correlation between the degree of vasospasm and CP degeneration was found. CONCLUSION Vasospasm of choroidal arteries may be at a serious degree in cases with SAH incurs damages on choroid plexuses, and affects structures which play important roles in immune, endocrine, detoxifying, thermoregulatory, and secretory functions of the brain resulting in worsened prognosis.

Abstract
AIM The aim of this study was to determine the relationship between ischemic neurodegeneration, of the petrosal ganglion of the glossopharyngeal nerve, and BP fluctuations, after subarachnoid hemorrhage (SAH). MATERIAL AND METHODS Twenty-four rabbits had their blood pressure and heart rhythms studied daily over 20 days. Then, the histopathology of the petrosal ganglion was examined in all animals. Normal and apoptotic neuron density of the petrosal ganglion and blood pressure values were compared statistically. RESULTS Mean total volume of the petrosal ganglia was calculated as 0.9 ± 0.34/mm3. BP level of control group was 96.1 ± 2.1 mmHg; 116.5 ± 4 mmHg of mild hypertension (HT) group and 128.1 ± 3.6mmHg in the severe HT group. When the groups were compared to each other they were significantly different. The level of normal-apoptotic neuron in control group was 11,240 ± 802/mm³ -40 ± 6.3/mm³; 9730 ± 148.7/mm³ - 1560 ± 256.2/mm³ in the mild HT group and 6870 ± 378.8/mm³-4240 ± 628.2/mm³ in the severe HT group. When the groups were compared to each other there was significantly difference. CONCLUSION Blood pressure variability observed in this study may be explained by ischemic neurodegeneration of petrosal ganglia caused by SAH. The results of this study suggest that petrosal ganglion ischemia has potential implications for the development of hypertension. These findings suggest that new treatment strategies should be considered for the treatment of SAH.

Abstract
Angiomyofibroblastoma is a rare, benign and recently defined soft tissue tumor. It generally arises from superficial soft tissues, especially from mesenchymal cells in the subepithelial myxoid stromal zone of the vulvovaginal region. The tumor is usually positive for estrogen and progesterone receptor. We report a pregnant woman who developed vulvar angiomyofibroblastoma within 2 months. The tumor was negative for estrogen and progesterone receptor.

Abstract
BACKGROUND In this study, we investigated the effects of treatment with chronic antihypertensive drugs (clonidine, methyldopa, amlodipine, ramipril and rilmenidine) on oxidant-antioxidant parameters and toxic effects on DNA in rat uterus tissue. In addition, uterus tissues were examined histopathologically. MATERIALS AND METHODS A total of 36 albino Wistar rats were divided into the following six groups: 0.075 mg/kg clonidine group; 100 mg/kg methyldopa group; 2 mg/kg amlodipine group; 2.5 mg/kg ramipril group; 0.5 mg/kg rilmenidine group; and the healthy group. Rats underwent chronic drug administration for 30 days and at the end, biochemical and histopathological examinations were performed. All data were subjected to one-way ANOVA test. RESULTS We divided these drugs into the following three groups according to their effects on rat uteri: (I) mild negative effects (clonidine), (II) moderate negative effects (rilmenidine, methyldopa) and (III) drugs which had severe negative effects (amlodipine, ramipril). CONCLUSION These data may help with selection of antihypertensive drugs, in order to determine which drugs have the lowest toxicity in pregnant and non-pregnant (pre-pregnancy) women.

Abstract
BACKGROUND The spinal arteries are innervated by several systems that contribute to the control of spinal cord blood flow. The sensory fibers of upper cervical nerves have vasodilatatory effect on the anterior spinal arteries (ASA). Subarachnoid hemorrhage (SAH) causes severe vasospasm by various neurochemical mechanisms. We examined whether there is a relationship between the neuron density of the C3 dorsal root ganglion and the severity of ASA vasospasm in SAH. METHODS This study was conducted on 20 rabbits. Four of them were used as baseline group. Experimental SAH has been applied to all of 16 animals by injecting homologous blood into cisterna magna. After 20 days of injection, ASA and C3 dorsal root ganglia (C3DRG) were examined histopathologically. ASA volume values and normal and degenerated neuron densities of C3DRG were estimated stereologically and the results were analyzed statistically. RESULTS The mean ASA volume was 1.050±0.450 mm³, [corrected] and the mean neuronal density of C3DRG was 10,500 ± 850 in all animals. The mean volume value of ASA was 0.970±0.150 [corrected] mm³, and the normal neuron density of C3DRG fell to 8,600 ± 400/mm³ in slight vasospasm group. In severe vasospasm-developed animals, mean volume value of ASA was 0.540±0.90 [corrected]mm³ and the normal neuron density of C3DRG fell to 5,500 ± 360/mm³. An inverse relationship between the degenerated neuronal density of the C3DRG and ASA volume values may indicate the severity of ASA vasospasm. CONCLUSION The neuron density of C3DRG may be an important factor on the regulation of ASA volume values and the continuation of spinal cord blood flow. Low neuron density of C3DRG may be considered as an important factor in the pathogenesis of severe ASA vasospasm in SAH.

Abstract
INTRODUCTION Hemangioma is a relatively common benign proliferation of blood vessels that primarily develops during childhood. Two main forms of hemangioma recognized: capillary and cavernous. The capillary form presents as a flat area consisting of numerous small capillaries. Cavernous hemangioma appears as an elevated lesion of a deep red color, and consists of large dilated sinuses filled with blood. The purpose of the study was to report the case of a capillary hemangioma in a patient and to describe the successful treatment of this case. CASE PRESENTATION The patient was a 19-year-old female who presented herself to the Atatürk University, Faculty of Dentistry, Department of Periodontology, with the complaint of bleeding and slowly enlarging mass on the upper right molar region. The lesion was diagnosed as capillary hemangioma after clinical examination and biopsy. Treatment consisted of scaling, root planning and surgical excision. Four months after surgery healing was occurred and two years later area of the lesion appeared completely normal as clinically. CONCLUSIONS The surface is highly keratinized and no further growth was evidenced during the two year of follow-up. Early detection and biopsy is necessary to determine the clinical behavior of the tumor and potential dentoalveolar complications.

Abstract
Solid pseudopapillary tumors of the pancreas, known as Frantz tumors, are rare pancreatic tumors that occur predominantly in women, with very few cases reported in men. We present the case of a 27-year-old female patient who came to the emergency room with an intense upper abdominal pain associated with nausea and vomiting and a palpable mass in the left upper quadrant. She was initially diagnosed with a post-traumatic pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenic preservation; the histopathological report showed a pseudopapillary solid tumor of the pancreas without malignant cells. In this report, a case of rare solid-pseudopapillary tumor of the pancreas is described. Our objective was to report an infrequent case of pancreatic pseudopapillary tumor and to carry out a review of the literature.

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
OBJECTIVE Approximately 50% of human malignancies present with mutations in p53, which is the most common tumor suppressor gene involved with human malignancies. Bcl-2 is a protooncogene, and expression of its protein product is associated with a better prognosis in several malignancies. Ki-67 is a marker of cellular proliferation. The purpose of this study was to determine whether simultaneous detection of p53, bcl-2 and Ki-67 using immunohistochemical staining can be used as a diagnostic factor in the assessment of human ovarian epithelial tumors. MATERIALS AND METHODS The study was performed on formalin-fixed, paraffin-embedded tissue samples from 75 epithelial ovarian tumors, 15 serous cystadenomas, 15 mucinous cystadenomas, 5 borderline serous cystadenomas, 5 borderline mucinous cystadenomas, 15 serous cystadenocarcinomas, 15 mucinous cystadenocarcinomas and 5 endometrioid carcinomas. Immunohistochemical staining was performed using monoclonal antibodies against p53, bcl-2, and Ki-67(MIB1). RESULTS Anti-p53 reactivity was observed in 14 tumors, all of which were malignant tumors, and no reactivity was observed in borderline or benign tumors. Overexpression of bcl-2 was observed in 12 benign neoplasms (40%), 5 of which were borderline (50%), but was not observed in any of the malignant tumors. There was a statistically significantly higher level of Ki-67 LI positivity in the malignant tumors than in the benign and borderline tumors (p<0.005). CONCLUSION These data show significant differences in the expression of these markers in ovarian tumors and suggest a possible role for these tumor-associated genes as supplemental tools in diagnostic pathology. Furthermore, our findings support the redesignation of low malignant potential tumors (current nomenclature) to benign ovarian carcinoma.

Abstract
Spinal cavernous malformations are collections of abnormal blood vessels in the spinal cord. They are rare and frequently accompany cranial cavernous angiomas. They exhibit clinical features representing the region of the spine affected by the cavernous malformation. We present a 12-year-old boy with bilateral hypothermia predominantly in the left arm and motor weakness of the upper extremities, and lesser involvement of the lower extremities The case had normal cranial magnetic resonance imaging, but MRI of cervical region revealed an intramedullary cavernous haemangioma confirmed with histopathological examination. The lesion was totally excised and hypothermia completely improved within 2 weeks after operation. We suggested that hypothermia in the extremities may be added as a rare finding to the list of the clinical features in cervical myelopathy.

Abstract
In the present study, we aimed to evaluate the effects of dehydroepiandrosterone (DHEA) on apoptosis of testicular germ cells after repair of testicular torsion in rats. Twenty-four adult male Sprague-Dawley rats were randomly divided into four groups, with six rats in each group: sham operation, torsion/detorsion (T/D), T/D + vehicle, and T/D + DHEA. Three hours before detorsion, 50 mg kg(-1) DHEA was given intraperitoneally to T/D + DHEA group. In all groups, bilateral orchiectomies were performed and both testicles were histologically examined, with apoptosis detected using the in situ DNA fragmentation [terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL)] system, with morphological damage detected using a four-level grading scale in each specimen. The testes of the sham group showed a normal histology. In T/D and T/D + vehicle groups, apoptotic spermatogonia and spermatocyte number were significantly higher than in the sham group (P < 0.01 for all). The T/D + DHEA group showed a reduction in apoptotic spermatocyte and spermatogonia number in seminiferous epithelia compared with T/D group (P < 0.01 for both). Apoptotic cell number of contralateral testes did not reveal any significant differences among these groups (P > 0.05). Specimens from T/D and T/D + vehicle had a significantly greater histological injury than sham and T/D + DHEA groups in the ipsilateral testes (P < 0.01 for both). Therefore, the results suggest that DHEA may be a protective agent for preventing apoptosis caused by testicular torsion.

Abstract
This report details the clinical and histopathological characteristics and course of glandular tularemia, an uncommon but significant cause of cervical lymphadenopathy in two children. Tularemia should be considered in the differential diagnosis of cases with non-tuberculosis, suppurative cervical lymphadenopathy, particularly in those not responding to penicillin treatment.

Abstract
BACKGROUND Human alveolar echinococcosis (AE) is a potentially fatal, chronically progressive hepatic infestation that is characterized by a long asymptomatic period in which an invasive tumor-like lesion develops. Several studies have suggested that genetic susceptibility to AE may be linked to HLA class II alleles. We investigated the association between AE and antigen HLA-A, B, C, DR and DQ profiles of patients with hepatic AE (HAE) in the eastern part of Turkey. METHODS This case-controlled study was performed on 44 unrelated patients with HAE and 76 control subjects. The diagnosis was supported by clinical, radiological, and histopathological evidence. The association of class I and class II HLA antigens was examined in the patients with HAE and control subjects. RESULTS There was an increase in the antigen frequencies of HLA-DRB1*15, HLA-DQB1*02, 06, 07 in the HAE patientscompared with those in the control group (P < 0.05, P < 0.001, P < 0.01, P < 0.05, respectively). HLA-DQB1*02, 06, 07 were more frequent in patients with stages III and IV who were classified according to the PNM staging system. CONCLUSIONS The present study indicates that susceptibility to HAE in the Turkish population is essentially HLA class II and poorly class I mediated, with HLA-26, and DRB1*015, DQB1* 02, 06, 07 with more allele distribution in the patient group. Our results are not similar to those of other studies, but contribute to the discussions on the association of HLA class I and class II alleles with AE.

Abstract
PURPOSE We aimed to evaluate the effects of dehydroepiandrosterone (DHEA) on antioxidant enzyme activities, lipid peroxidation, and histopathologic changes in both testes after unilateral testicular torsion and detorsion. METHODS Twenty-four adult male Sprague-Dawley rats were randomly divided into 4 groups (n = 6 for each group): sham operation, torsion/detorsion (T/D), T/D + vehicle, and T/D + DHEA. Three hours before detorsion, 50 mg/kg DHEA was given intraperitoneally to the T/D + DHEA group. Testicular ischemia was achieved by twisting the left testis 720 degrees clockwise for 3 hours, and reperfusion was allowed for 24 hours after detorsion. In all groups, bilateral orchiectomies to determine the testicular tissue catalase (CAT) and superoxide dismutase activities and malondialdehyde (MDA) levels and histopathologic examination were performed. RESULTS Compared with those from the sham group, CAT activities in the ipsilateral testis obtained from the T/D group were significantly lower and MDA levels were significantly higher (P < .05 for all). Administration of DHEA prevented increases in MDA levels and decreases in CAT and superoxide dismutase activities when compared to the T/D group. Specimens from the T/D and the T/D + vehicle groups had a significantly greater histologic injury than the specimens from the sham and the T/D + DHEA groups had (P < .01 for both). CONCLUSIONS The results suggest that DHEA may be a protective agent for preventing biochemical and histopathologic changes related to oxidative stress in testicular injury caused by testis torsion.

Abstract
In many physiological bodily functions, and in the pathogenesis of inflammation, ions are exchanged between intracellular and extracellular areas. Amiodarone is a multiple ion channel (Ca++, Na+, K+) blocking drug, effective anti-arrhythmic drug, and phospholipase inhibitor. The aim of this study is to examine a role of polymorphonuclear leukocyte infiltration in amiodarone's anti-inflammatory effect on experimental paw inflammation. After rats had been assigned to groups, their normal right hind paw volumes were measured using a plethysmometer. Amiodarone (25, 50 and 100 mg/kg) and distilled water were administrated to the experimental and control groups, respectively, by ip route. Thirty minutes later, paw edema was induced in rats by subplantar injection of 0.1 ml of histamine (0.1%) to those paws. Subsequent volume readings for those paws were carried out at 30-min intervals. Results were expressed as percentages of change from the initial volumes. After the final measurements, the animals were killed by decapitation and their paw tissues were cut for pathological investigation. Amiodarone dose-dependently decreased the paw edema (25.05, 48.71 and 74.97%), and reduced polymorphonuclear leukocyte infiltration in the paw tissue (55.65, 69.76 and 84.58%). Our findings support the view that amiodarone dose-dependently exerts a powerful anti-inflammatory activity. This effect of amiodarone may be due to the activation of nitric oxide resulting from its calcium channel antagonistic effects, to the inhibition of phospholipase A2 and/or to a reduction in neutrophil movement and activation, which may reduce free radical production and proteolytic enzyme release.

Abstract
PURPOSE In this study we aimed to investigate the value of contrast enhanced dynamic MR imaging (DMI) in the diagnosis of nodular abdominal endometriosis. SUBJECTS AND METHODS Fourteen patients with surgically and pathologically proven endometriosis were examined with DMI. The patients were 22-54 years old (mean age 30.8 years). The dynamic MR studies of these patients were retrospectively reviewed by two radiologists who were aware of the clinical data. Nodular masses showing enhancement were evaluated for size, margins, and signal intensity on T1- and T2-weighted MR sequences. The protocol was tailored to selectively determine the diagnostic utility of signal intensity time course analysis for the behavior of nodular endometriosis and endometrial tissue, in DMI. Contrast-enhanced DMI was performed and the time-intensity curves of the lesions and the uterine endometrial tissue of each patient were compared. Mean enhancement values were calculated. Each DMI was evaluated for signal intensity value. RESULTS In 8 (57%) of 14 patients, we found endometriosis in the abdominal wall. All patients with abdominal wall endometriosis had pelvic surgical operation history. Diameter of nodular endometriosis determined in the abdominus muscle ranged between 3 and 40 mm. Of eight cases, five had only one lesion and three had multiple lesions. Remaining 6 (43%) cases had deep pelvic endometriosis located in the uterosacral ligaments (n = 3), rectosigmoid (n = 2), and rectovaginal septum (n = 1). Diameter of pelvic endometriosis ranged between 9 and 53 mm. Noncontrast mean signal intensity of endometriosis and endometrial tissue were 280 +/- 73 and 216 +/- 20, respectively. The mean values of both endometriosis and normal endometrial tissue were calculated for each patient examined with five-slice DMI. All of the curves showed significant correlation. The lesion showed significant enhancement in the course of time similar to the endometrial tissue in all patients. CONCLUSION Our study was inspired from the fact that endometriosis is the ectopic endometrial tissue and we thought that endometrial tissue and endometriomas should have similar vascularity. In this way imaging with MR, getting the time-intensity curves and experiencing the correlation between the endometriosis and endometrial tissue may support the diagnosis in the cases with suspected endometriosis. This first study shows that the ectopic nodular endometriosis can easily be identified with dynamic MRI. It may be used to differentiate nodular endometriosis from the other pathologic conditions of abdominal wall and pelvis.

Abstract
BACKGROUND A marginal ulcer developing after an initial operation for gastroduodenal ulcer is a serious threat to the patient, and a challenge to surgeons. Helicobacter pylori is the primary cause of peptic ulcer disease. However, its role in ulcer recurrence, especially of marginal ulcer (MU), after peptic ulcer surgery is unclear. This study aimed to determine any association between H. pylori infection and perforated MU by comparing the prevalence of H. pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) use in patients with perforated (PMU) and in those with nonperforated MU (NPMU). STUDY DESIGN The study retrospectively evaluated the records of 16 patients with PMU who underwent surgical treatment and 24 patients with NPMU who underwent medical treatment in Atatürk University, School of Medicine, Department of General Surgery and Gastroenterology, between January 1995 and December 2004. RESULTS The rate of H. pylori in the PMU group was significantly higher than that of the NPMU group (P < 0.01). There was a significant relationship between NSAID consumption and PMU compared with NPMU patients (P < 0.01). There was also a significant relationship between NSAID consumption and H. pylori and PMU (P < 0.01). CONCLUSION Eradication of H. pylori after the first PMU operation especially in cases with impaired hemodynamics, severe peritoneal contamination, and/or a diameter smaller than 1 cm and avoiding the use of NSAIDs will surely reduce the risk of relapsing ulcers.

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.

The incidence of intestinal tuberculosis (ITB) has been increasing in the West, due to the AIDS epidemic, transglobal immigration, IV drug abuse, an aging population, and an increase in the number of immunocompromised patients. Obstruction and perforation of the intestine are the most common and serious complications of ITB. Another complication, tuberculous liver abscess (TLA), is rare and usually associated with foci of infection in the lung or gastrointestinal tract. We report a case of a 17-year-old boy with Down syndrome who presented with multiple TLAs secondary to obstructive and multiple perforated ileal tuberculosis.

Abstract
Linear atrophoderma of Moulin has a distinctive disease pattern characterized by hyperpigmented atrophoderma and was described originally in 1992. It follows the line of Blaschko, and occurs without preceding inflammation, subsequent induration or scleroderma. The lesions usually develop during childhood or adolescence, and the prognosis is good. The diagnosis is made clinically and histopathologically. In our 18-year-old male patient, there were atrophic plaques unilaterally located on the trunk and arm, and white discoloration on all finger nails. Histopathological examination revealed epidermal atrophy together with disruption of collagen fibres.

Abstract
BACKGROUND Meningitis, termed as foreign material collection in the subarachnoid space, leads to various meningeal, cerebral and spinal cord pathologies. Meningitis still remains a problematic disease with severe complications in spite of advanced medical technology. AIMS In this study, we aimed to investigate the role of cisternal irrigation in the prevention of meningitis complications. SETTING AND STUDY DESIGN: Experimental study was done in the Social Security Hospital of Erzurum. Histopathological specimens were evaluated in the Pathology Department in the Ataturk University Research Hospital, Erzurum, Turkey. MATERIALS AND METHODS This study was conducted on twelve lambs. Experimental meningitis was achieved with streptococcus pneumonia. Two animals were not treated. Ten animals were given Cefotaxime (4 x 1g/day) for 20 days, and additionally half of these animals underwent cisternal irrigation. Then, all animals were sacrificed and brains were observed histopathologically. RESULTS Massive purulent CSF formation, hemorrhagic cortical lesions, vascular congestion, leptomeningeal and cortical adhesions and brain edema were observed in the non-irrigated group, but these findings were observed slightly or absent in the irrigated group. CONCLUSION Meningitis can affect all central neural tissues, consequently serious central nervous system lesions may develop. The irrigation procedure may decrease the percentage and severity of meningitis complications by way of the excretion of inflamed purulent collection from the subarachnoid spaces.

Abstract
BACKGROUND Monopolar electrocauterization (MEC) is widely used in spine surgery however electrical currents are hazardous for neural tissues, such as the spinal ganglia sited in the intervertebral foramina. We aimed to investigate the effects of MEC on spinal ganglia. METHOD Fifteen male hybrid rabbits were included in the study. Three of the animals were used to analyze the findings regarding spinal ganglia without operation. The remaining animals underwent L4-5 disc surgery. For intra-operative facet denervation MEC was used for half of the animals. After one month, all animals were sacrificed and L5 spinal ganglia were removed for histopathological examination. The number and morphological changes of neurons in spinal ganglia were examined. FINDINGS The mean number of live neurons was 22610 in non-operated rabbits; 21617 in the non-MEC group and 16692 in the MEC group. Neuronal degeneration was more prominent in the MEC group than in the non-MEC group. CONCLUSIONS MEC used during spine surgery may be injurious to spinal ganglia and should be used with caution.

Abstract
Patients who have vasculitis in pregnancy generally have a grim prognosis. Vasculitis occurring during pregnancy may have a more aggressive course and require more aggressive treatment than vasculitis occurring at other times. A 29-year-old woman who presented in the 16th week of her third intrauterine pregnancy was diagnosed as having active microscopic polyangiitis. Therapy consisting of high-dose methylprednisolone and cyclophosphamide was instituted, but the patient died of pulmonary infection due to methicillin-resistant Staphylococcus aureus.

Abstract
Female sex steroids may play a role in the proliferation of meningiomas, which usually have a high level of progesterone receptors (PgRs). We aimed to investigate the presence of PgRs and the Ki-67 labeling index (Ki-67 LI) in meningioma cases (N = 110) in relation to the severity of the disease. We studied PgR immunoreactivities and the Ki-67 LI in paraffin-embedded sections from meningiomas. Immunodetection of PgRs was conducted with peroxidase-antiperoxidase complex. Immunodetection of Ki-67 antigen was achieved by streptavidin-biotinperoxidase complex. Of 110 meningiomas, in 57 (52%) the immunostaining for PgRs was moderately to strongly positive (Group 1), in 23 (20%) weakly positive (Group 2), and in 30 (28%) negative (Group 3). The positive immunostaining rate for the PgR in the benign meningiomas (76%) was significantly higher than that in nonbenign tumors. The positive immunostaining rate for the PgR was significantly higher in women (81%) than men (55%). The results suggested that progesterone may play a role in the growth of meningiomas. Our results confirmed that the immunodetection of the PgR and Ki-67 antigens on the paraffin sections of meningiomas provides a valuable tool for estimating the biological behavior of meningiomas.

Abstract
Seventy-five cases of invasive ductal carcinoma (IDC) on whom axillary lymph node dissection and mastectomy were performed between 1996 and 2000 were reviewed histopathologically. The slides were stained immunohistologically with p53 and Bcl-2. In 40 cases we observed 53% Bcl-2 and 69% p53 positivity. There were correlations between p53 and tumour grade, and also between p53 and Bcl-2. We did not observe any connection between the main histopathological prognostic factors--lymph node metastasis, tumour size, tubule formation, pleomorphism--and p53/Bcl-2. In our study, IDC with a high mitotic index and poor differentiation showed mutant p53 positive staining. Expression of Bcl-2 is associated with low nuclear grade and absence of mutant p53. This study was designed to reveal the correlation between histopathological findings and the expression of p53/Bcl-2 on prognosis.
