Sternal cleft is a rare congenital malformation resulting from a fusion failure of the sternum and often patients have no clinical signs at birth. The defect is usually divided into partial or complete forms and is often accompanied by other anomalies. We herein report a case of upper sternal cleft that was repaired in the neonatal period by primary closure after partial thymectomy. The patient was discharged 9 days after the operation with good condition and normal respiratory movements. Sternal cleft is a rare case, with little more than 100 cases published worldwide.

Although symptomatic Mickel's Diverticulum (MD) in infants is rare, we report a case of perforated (MD) at birth in a full term male with signs of peritoneal irritation. Because of the rareness of perforated (MD) in infants, predicting the preoperative diagnosis is so difficult, but it doesn't affect the prognosis.

Objectives: To investigate the effects of syringaldehyde (SA) on the antioxidant and oxidant system in spinal cord ischemia (SCI)., Methods: These study and experiments were conducted at Medical Research Center, Çanakkale Onsekiz Mart University, Çanakkale, Turkey, between 2014-2018. Eighteen New Zealand White adult male rabbits were randomly divided into 3 groups (n=6). Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), myeloperoxidase (MPO) activities, and malondialdehyde (MDA) levels were measured in the spinal cord tissues. Degenerated neurons, hemorrhage and in ammatory cell migration in the spinal cord were investigated histopathologically. Expressions of neuronal nitric oxide synthase (nNOS), caspase-3, and nuclear factor-κB (NF-κB) were evaluated immunohistochemically. Clinically, it was evaluated with modified Tarlov score., Results: Biochemically, there was an expected decrease in SOD, CAT, and GPx enzyme activities in ischemia groups, there was also an increase in MPO activity at the same time. When the enzyme activities spinal cord ischemia/ reperfusion (SCI/R)+SA, control and SCI/R groups were compared, the difference was found to be statistically significant (p less than 0.05). Glutathione peroxidase enzyme activity levels were very low in ischemia group compared to the significant increase in the SA group (p less than 0.05). Histopathologically, when SCI/R and SCI/R+SA groups were compared, there were statistically significant differences in the number of degenerative neurons and amount of hemorrhage; this comparison shows the significance of treatment in terms of inflammatory cell migration (p less than 0.05). The expressions of nNOS, caspase-3, and NF-κB were found significantly increased in SCI/R group compared to the control group (p less than 0.05). Syringaldehyde treatment decreased nNOS, caspase-3, and NF-κB expressions immunohistochemically. Clinical evaluation showed improvement in the SA-treated group., Conclusion: Syringaldehyde therapy administered for protective purposes may reduce oxidative stress, degenerative changes and in ammatory cell migration in the ischemic spinal cord.Saudi Med J 2020; Vol. 41 (4): 341-350doi: 10.15537/smj.2020.4.24993 How to cite this article:Malçok UA,  Aras AB, Şehitoğlu MH, Akman T, Yüksel Y.

Objectives: The objective of the study is to understand the impact of adjuvant radiotherapy (RT) and prognostic factors for patients diagnosed with uterine carcinosarcoma., Materials and Methods: The records of 31 patients receiving adjuvant RT between the dates of September 2003-January 2013 in our clinic were evaluated retrospectively. Surgery was performed in 27 (87%) patients as staging laparotomy, for 4 patients as total abdominal hysterectomy and bilateral salpingo-oophorectomy. Pelvic external beam radiotherapy (EBRT) was 4500-5040 cGy in 25-28 fractions. In addition, 23 patients received brachytherapy following EBRT, 12 patients received adjuvant, and 1 patient received neoadjuvant chemotherapy (CT)., Results: The median age was 63 (between 30 and 78). The stage distribution of the patients was as follows: Stage I, 20 (64%); Stage II, 7 (23%), and Stage III, 4 (13%) patients. Five-year locoregional control (LRC) rate was 100%, disease-free survival (DFS) and overall survival (OS) rates were 65.5% and 66.2%, respectively. Stage I or II patients have a tendency for better 5-year OS and DFS rates than Stage III patients (73.1% vs. 42.9% and 72.7% vs. 42.9%; P = 0.065 and 0.051). Regarding lymph node dissection was performed or not, 5-year OS (64.7% vs. 75.0%) was not statistically different between groups (P = 0.77). Five-year OS and DFS rates were 69.2% and 61.5% for patients receiving CT (adjuvant or neoadjuvant) versus 63.7% and 68.8% for patients not receiving CT; P = 0.63 and P = 0.89, respectively. Based on the analysis of peritoneal washings, 5-year OS was 0% for patients with malignant or suspicious cytology whereas 89% for patients with benign cytology (P = 0.000). A negative correlation was observed between mitotic count of sarcomatous component and DFS time (rs = -0.812 and P = 0.05)., Conclusions: Surgery and adjuvant RT seem beneficial for excellent LRC rate. However, survival rates are low due to distant metastases. Thus, there is a great need for better systemic therapies., Competing Interests: None

Aim: In the relevant literature, there is no experimental study that investigated the axon protective effects of syringic acid- a polyphenol compound- with an anti-oxidant capacity on ischemia/reperfusion injury., Material and Methods: The rats were randomly divided into four groups: Control group (no medication or surgical procedure), Sham group, Syringic acid group, and Methyprednisolone (MP) Group. Ischemia was achieved by abdominal aorta clamping and all animals were sacrificed 24 hours after ischemia. Harvested sciatic nerve segments were investigated histopathologically and for tissue biochemistry., Results: Ischemic fiber degeneration scores were found significantly lower in syringic acid and MP groups than sham group. Additionally, apoptosis-related cysteine peptidase caspase-3 immunostaining scores were lower in syringic acid and MP groups. Biochemically, superoxide dismutase and nuclear respiratory factor 1 values were significantly higher in syringic acid group compared to those of control and sham groups while malondialdehyde levels were significantly lower in the syringic acid group., Conclusion: Syringic acid reduces oxidative stress and axonal degeneration in rat sciatic nerve after ischemia/reperfusion injury. Therefore, syringic acid may play a role in the treatment of peripheral nerve injuries due to ischemia/reperfusion.

Aim: The purpose of this study was to evaluate the possible protective/therapeutic effects of aloe vera (AV) on ischemia-reperfusion injury (I/R) of spinal cord in rats., Materials and Methods: A total of 28 Wistar Albino rats were divided into four random groups of equal number (n = 7). Group I (control) had no medication or surgery; Group II underwent spinal cord ischemia and was given no medication; Group III was administered AV by gastric gavage for 30 days as pre-treatment; Group IV was administered single dose intraperitoneal methylprednisolone (MP) after the ischemia. Nuclear respiratory factor-1 (NRF1), malondialdehyde (MDA) and superoxide dismutase (SOD) levels were evaluated. Tissue samples were examined histopathologically and neuronal nitric oxide synthase (nNOS) and nuclear factor-kappa B (NF-κB) protein expressions were assessed by immunohistochemical staining., Results: NRF1 and SOD levels of ischemia group were found to be lower compared to the other groups. MDA levels significantly increased after I/R. Treatment with AV and MP resulted in reduced MDA levels and also alleviated hemorrhage, edema, inflammatory cell migration and neurons were partially protected from ischemic injury. When AV treatment was compared with MP, there was no statistical difference between them in terms of reduction of neuronal damage. I/R injury increased NF-κB and nNOS expressions. AV and MP treatments decreased NF-κB and nNOS expressions., Conclusions: It was observed that aloe vera attenuated neuronal damage histopathologically and biochemically as pretreatment. Further studies may provide more evidence to determine the additional role of aloe vera in spinal cord ischemia reperfusion injury.

Purpose: Vulvar cancer is a relatively uncommon type of gynecologic cancer. The aim of this study is to analyze the treatment results and prognostic factors of vulvar cancer., Methods: Forty-four vulvar cancer patients treated between 2000 and 2011 at the Department of Radiation Oncology, Ege University Faculty of Medicine, were retrospectively reviewed. External radiotherapy (RT) was applied with 6-18 MV linear accelerators with 1.8 Gy daily fractions with a median total dose of 50.4 Gy (45-59.4 Gy) for postoperative cases and 64.8 Gy (range 54-66 Gy) for definitive cases. Statistical analyses were performed with SPSS 13.0., Results: Among 44 patients with a median age of 68 years (range 28-86), 14 (31.8%) were treated with curative and 30 (68.2%) were treated with postoperative RT or radiochemotherapy (RCT). According to International Federation of Gynecology and Obstetrics staging, 11 (25%) had stage IB, 10 (22.7%) had stage II, 6 (13.6%) had stage IIIA, 5 (11.4%) had stage IIIB, and 12 (27.3%) had stage IVA disease. Within a median of 24 months (range 6-135) of follow-up, 11 (27.3%) patients had local recurrence, 8 had regional recurrence, 2 had both local and regional recurrence, and 6 had distant metastases. Five-year locoregional, disease-free, and overall survival rates were 45%, 40%, and 54%, respectively. Older age, poor tumor differentiation, positive surgical margin, and lymphovascular space invasion were found to be important prognostic factors for disease-related outcomes., Conclusions: Prognosis of vulvar cancer remains poor even with a multidisciplinary approach. Molecular prognostic factors need to be defined for individualized treatment options to achieve better treatment results.

Purpose: Aloe vera is compound which has strong antioxidant and anti-inflammatory effects. We investigated the neuroprotective role of aloe vera treatment in rats with experimental sciatic nerve ischemia/reperfusion injury., Methods: Twenty-eight male Wistar Albino rats were divided equally into 4 groups. Groups; Control group (no surgical procedure or medication), sciatic nerve ischemia/reperfusion group, sciatic nerve ischemia/reperfusion+aloe vera group and sciatic nerve ischemia/reperfusion+methylprednisolone group. Ischemia was performed by clamping the infrarenal abdominal aorta. 24 hours after ischemia, all animals were sacrificed. Sciatic nerve tissues were also examined histopathologically and biochemically., Results: Ischemic fiber degeneration significantly decreased in the pre-treated with aloe vera and treated with methylprednisolone groups, especially in the pre-treated with aloe vera group, compared to the sciatic nerve ischemia/reperfusion group (p<0.05). A significant decrease in MDA, an increase in NRF1 level and SOD activity were observed in the groups which obtained from the AV and MP groups when compared to the sciatic nerve ischemia/reperfusion group. When all results were analysed it was seen that the aloe vera group was not statistically different compared to the MP group (p>0.05)., Conclusions: Aloe vera is effective neuroprotective against sciatic nerve ischemia/reperfusion injury via antioxidant and anti-inflammatory properties. Also aloe vera was found to be as effective as MP., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Aim: The objective of this study was to investigate the effect of using 2 different surgical techniques (curette or high-speed drill) in anterior cervical discectomy surgery on the healing of cases., Material and Methods: Fifty-four operated cervical disc hernia cases were retrospectively examined in 2 groups. Discectomy and osteophytectomy were carried out in Group A by using a high-speed drill, while a curette was used for group B. Preoperative and postoperative computerized tomography and direct radiography were performed. Cervical disc height, cervical and segmental lordotic angles were calculated. The visual analogue scale and Odom's criteria were used in the assessment of pain and clinical healing. The fusion ratio of both groups was compared. The Mann-Whitney U test was used to compare data from the groups., Results: Satisfactory results were obtained in the groups where high-speed drill and curette were used. Independently from the surgical technique, pain scores were significantly reduced in both groups after surgery. No radiologically significant differences were identified between the two groups within the postoperative period., Conclusion: Either high-speed drill or curette can be chosen for the osteophytectomy and discectomy stages of anterior cervical discectomy operations.

Aim: The aim of this study is to compare the different types of fusion materials known as PEEK cages used during anterior cervical discectomy (ACD) surgery., Material and Methods: A total of 67 patients were operated and evaluated retrospectively under two groups (group A: 35 PEEK cage patients, group B: 32 bladed PEEK cage patients) between 2009 and 2013. Preoperative and postoperative (postoperative first day, postoperative 1st, 3rd and 12-24th mo) images were obtained. The cervical disc heights, cervical and segmental lordotic angles of the operated levels were calculated. Pain assessment was performed and fusion rates were also compared. Mann-Whitney U test was applied to compare the outcomes., Results: The pain scores (especially for arm pain) were decreased significantly in both groups after surgery regardless of the type of operation technique (P < 0.05). There were no significant differences between both groups at the disc height measurements of operated levels in postoperative periods (P > 0.05). In addition to these; there was no significant difference between both groups of segmental and cervical lordodic angles in postoperative periods (P > 0.05). There was no statistically significant difference between the fusion rates and pain scores of both groups (P > 0.05)., Conclusion: The PEEK cage and bladed PEEK cages can be used safely to obtain fusion after ACD.

Aim: The intervertebral disc starts to degenerate when a human being begins to stand and learn to walk. It is known that many extrinsic, intrinsic and genetic factors play a role in disc degeneration. In this study, we examined whether the matrix metalloproteinase 11 might be associated with intervertebral disc degeneration., Material and Methods: Fifty-six patients with lumbar disc herniations who were operated at Göztepe Education and Research Hospital, Neurosurgery Clinic between September 2008 and December 2009 were prospectively reviewed. History and complaints were obtained from the case reports. Neuroradiological evaluation was performed with magnetic resonance imaging. Surgical findings of cases were reported in the operation notes. Microscopic posterior hemipartial laminectomy and discectomy were performed in all cases. Degenerated herniated disc material of all cases extracted during surgery was evaluated with immunohistochemical staining in Marmara University, Institute of Neurological Sciences, Pathology Laboratory., Results: Comparing the immunohistochemical staining of cases who were 50 years or younger and cases who were over 50 years old, statistical significance was determined., Conclusion: Matrix metalloproteinase 11 has a role in degenerating intervertebral disc disease, but it is not the only factor. Matrix metalloproteinase 11 might be a genetic factor in young-middle aged patients.

The aim of the study was to determine the effect of coumaric acid on sciatic nerve ischemia/reperfusion (SNI) injury in rats. The rats were randomly divided into four groups: control group (no medication or surgical procedure), SNI group, SNI + coumaric acid (CA) group, and SNI + methylprednisolone (MP) group. Ischemia was achieved by abdominal aorta clamping, and all animals were sacrificed 24 h after ischemia. Harvested sciatic nerve segments were investigated histopathologically and for tissue biochemistry. A significant decrease in MDA, an increase in NRF1 levels, and increase in SOD activity were observed in the groups which received coumaric acid and methylprednisolone when compared to the corresponding untreated group (p < 0.05). Ischemic fiber degeneration significantly reduced in the SNI + CA and SNI + MP groups, especially in the SNI + MP group, compared to the SNI group (p < 0.05). Beta amyloid protein expressions were significantly decreased in the SNI + CA group compared to the SNI group (p < 0.05). Our study revealed that coumaric acid treatment after ischemia/reperfusion in rat sciatic nerves reduced oxidative stress and axonal degeneration. Therefore, coumaric acid may play a role in the treatment of peripheral nerve injuries due to ischemia/reperfusion.

Acute arterial occlusions via different vascular pathologies are the main causes of spinal cord ischemia. We investigated neuroprotective effects of syringic acid on spinal cord ischemia injury in rats. Rats were divided into four groups: (I) sham-operated control rats, (II) spinal cord ischemia group, (III) spinal cord ischemia group performed syringic acid, and (IV) spinal cord ischemia group performed methylprednisolone intraperitoneally. Spinal cord ischemia was performed by the infrarenal aorta cross-clamping model. The spinal cord was removed after the procedure. The biochemical and histopathological changes were observed within the samples. Functional assessment was performed for neurological deficit scores. A significant decrease was seen in malondialdehyde levels in group III as compared to group II (P < 0.05). Besides these, nuclear respiratory factor-1 and superoxide dismutase activity of group III were significantly higher than group II (P < 0.05). In histopathological samples, when group III was compared with group II, there was a significant decrease in numbers of apoptotic neurons (P < 0.05). In immunohistochemical staining, BECN1 and caspase-3-immunopositive neurons were significantly decreased in group III compared with group II (P < 0.05). The neurological deficit scores of group III were significantly higher than group II at twenty-fourth hour of ischemia (P < 0.05). Our study revealed that syringic acid pretreatment in spinal cord ischemia/reperfusion reduced oxidative stress and neuronal degeneration as a neuroprotective agent. Ultrastructural studies are required for syringic acid to be developed as a promising therapeutic agent to be utilized for human spinal cord ischemia in the future.

The main causes of spinal cord ischemia are a variety of vascular pathologies causing acute arterial occlusions. We investigated neuroprotective effects of coumaric acid on spinal cord ischemia injury in rats. Rats were divided randomly into four groups of eight animals as follows: control, ischemia, ischemia + coumaric acid, and ischemia + methylprednisolone. In the control group, only a laparotomy was performed. In all other groups, the spinal cord ischemia was performed by the infrarenal aorta cross-clamping model. Levels of malondialdehyde and nuclear respiratory factor 1 were analyzed, as were the activity of superoxide dismutase. Histopathological and immunohistochemical evaluations were performed. Neurological evaluation was performed with the Tarlov scoring system. The ischemia + coumaric acid group was compared with the ischemia group, and a significant decrease in malondialdehyde and levels was observed. Nuclear respiratory factor 1 level and superoxide dismutase activity of the ischemia + coumaric acid group were significantly higher than in the ischemia group. In histopathological samples, the ischemia + coumaric acid group is compared with the ischemia group, and there was a significant increase in numbers of normal neurons. In immunohistochemical staining, hypoxia-inducible factor-1α and NF-kappa B immunopositive neurons were significantly decreased in the ischemia + coumaric acid group compared with that in the ischemia group. The neurological deficit scores of the ischemia + coumaric acid group were significantly higher than the ischemia group at 24 h. Our results revealed for the first time that coumaric acid exhibits meaningful neuroprotective activity following ischemia-reperfusion injury of the spinal cord.

Cerebral ischemia is still one of the most important topics in neurosciences. Our study aimed to investigate the neuroprotective and anti-oxidant effects of glycyrrhizic acid on focal cerebral ischemia in rats. Twenty-four rats were divided equally into three groups. A middle cerebral artery occlusion model was performed in this study where sham and glycyrrhizic acid were administered intraperitoneally following middle cerebral artery occlusion. Group I was evaluated as control. Malondialdehyde (MDA), superoxide dismutase (SOD), and nuclear respiratory factor-1 (NRF1) levels were analyzed biochemically on the right cerebral hemisphere, while ischemic histopathological studies were completed to investigate the anti-oxidant status. Biochemical results showed that SOD and NRF1 levels were significantly increased in the glycyrrhizic acid group compared with the sham group while MDA levels were significantly decreased. On histopathological examination, cerebral edema, vacuolization, degeneration, and destruction of neurons were decreased in the glycyrrhizic acid group compared with the sham group. Cerebral ischemia was attenuated by glycyrrhizic acid administration. These observations indicate that glycyrrhizic acid may have potential as a therapeutic agent in cerebral ischemia by preventing oxidative stress.

Many studies of brain ischemia have shown the role played by massive ischemia-induced production of reactive oxygen species, the main mechanism of neuronal death. However, currently, there is no treatment choice to prevent cell death triggered by reactive oxygen species. In our study, we researched the effects of tannic acid, an antioxidant, on the ischemic tissue of rats with induced middle cerebral artery occlusion. The animals were divided into three groups of eight animals. The sham group were only administered 10 % ethanol intraperitoneally, the second group had middle cerebral artery occlusion induced and were given 10 % ethanol intraperitoneally, while the third group had middle cerebral artery occlusion with 10 mg/kg dose tannic acid dissolved in 10 % ethanol administered within half an hour intraperitoneally. The rats were sacrificed 24 h later, and brain tissue was examined biochemically and histopathologically. Biochemical evaluation of brain tissue found that comparing the ischemic group with no treatment with the tannic acid-treated ischemia group; the superoxide dismutase (SOD) levels were higher, malondialdehyde (MDA) levels were lower, and nuclear respiratory factor-1 (NRF-1) was higher in the tannic acid-treated group. Histopathological examination showed that the histopathological results of the tannic acid group were better than the group not given tannic acid. Biochemical and histopathological results showed that tannic acid administration had an antioxidant effect on the negative effects of ischemia in brain tissue.

Background: In recent years, white blood cells (WBCs) and their subtypes have been studied in relation to inflammation. The aim of our study was to assess the relationship between neutrophil-lymphocyte ratio (NLR) and ankylosing spondylitis (AS)., Materials and Methods: We enrolled a total of 177 patients, 96 AS and 81 healthy controls. Complete blood count, WBC, neutrophil and lymphocyte levels were measured, and the NLR was calculated. In the assessment of AS, we used the erythrocyte sedimentation rate, C-reactive protein (CRP), the Bath Ankylosing Spondylitis Disease Activity Index, and the Bath Ankylosing Spondylitis Functional Index., Results: In the present study, 96 AS and 81 healthy individuals were enrolled. The mean age was 43.8 ± 12.9 and 46.5 ± 11.2 years, respectively. Mean disease duration of AS patients was 6.9 ± 5.6 years (median = 5, min-max = 1-25). The patients with AS had a higher NLR than the control individuals (mean NLR, 2.24 ± 1.23 and 1.73 ± 0.70, respectively, P < 0.001). A statistically significant positive correlation was observed between NLR and CRP (r = 0.322, P = 0.01). The patients receiving antitumor necrosis factor α therapy had a lower NLR than the patients receiving nonsteroidal anti-inflammatory drug therapy (mean NLR, 1.71 ± 0.62 and 2.41 ± 1.33, respectively, P = 0.02)., Conclusion: NLR may be seen as a useful marker for demonstrating inflammation together with acute phase reactants such as CRP and in evaluating the effectiveness of anti-TNF-α therapy., (© 2014 Wiley Periodicals, Inc.)

[Purpose] The aim this study was to assess the relation between bone mineral density (BMD) and mean platelet volume (MPV) in ankylosing spondylitis (AS) patients, and evaluate the diagnostic role of the diffusion-weighted magnetic resonance imaging (MRI). [Subjects and Methods] Fifty patients diagnosed with AS were divided into two groups on the basis of BMD, a normal group (n=30) and an osteopenic (n=20) group. [Results] Duration of disease in the group with a normal BMD was 10.3±7.0 years, while it was 16.7±12.2 years in the osteopenia group. MPV was high in the osteopenia group, while no significant differences were observed between the groups in terms of apparent diffusion coefficient (ADC) and platelet distribution width (PDW). There was a positive correlation between MPV and duration of disease. Correlations between ADC value and the lumbar T score, femoral neck T score, and duration of disease were insignificant. A negative correlation was observed between BMD and disease duration. [Conclusion] Diffusion-weighted imaging provides valuable results in osteoporosis but is not a suitable technique for evaluating BMD in patients with AS because of the local and systemic inflammatory effects in the musculoskeletal system. The common pathophysiology of atherosclerosis and osteoporosis plays an important role in the negative correlation observed between MPV and BMD in patients with AS.

Objectives: Stroke poses a crucial risk for mortality and morbidity. Our study aimed to investigate the effect of p-coumaric acid on focal cerebral ischemia in rats., Material and Methods: Rats were randomly divided into four groups, namely Group I (control rats), Group II (ischemia rats), Group III (6 hr ischemia + p-coumaric acid rats) and Group IV (24 hr ischemia + p-coumaric acid rats). Cerebral ischemia was induced via intraluminal monofilament occlusion model. In all groups, the brain was removed after the procedure and rats were sacrificed. Malondialdehyde, superoxide dismutase and nuclear respiratory factor-1 were measured in the ischemic hemisphere. The histopathological changes were observed in the right hemisphere within the samples. Functional assessment was performed for neurological deficit scores., Results: Following the treatment, biochemical factors changed significantly. Histopathologically, it was shown that p-coumaric acid decreased the oxidative damage. The neurological deficit scores of p-coumaric acid-treated rats were significantly improved after cerebral ischemia., Conclusion: Our results showed that p-coumaric acid is a neuroprotective agent on account of its strong anti-oxidant and anti-apoptotic features. Moreover, p-coumaric acid decreased the focal ischemia. Extra effort should be made to introduce p-coumaric acid as a promising therapeutic agent to be utilized for treatment of human cerebral ischemia in the future.

Stroke is still a major cause of death and permanent neurological disability. As humic acids are well-known antioxidant molecules, the purpose of this study was to investigate the potential neuroprotective effects of humic acid in a focal cerebral ischemia model. Twenty-four rats were divided equally into three groups. A middle cerebral artery occlusion model was performed in this study where control (group II) and humic acid (group III) were administered intraperitoneally following an ischemic experimental procedure. Group I was evaluated as sham. Malondialdehyde (MDA), superoxide dismutase (SOD), and nuclear respiratory factor-1 (NRF-1) levels were analyzed biochemically on the right side of the ischemic cerebral hemisphere, while ischemic histopathological studies were completed on the left side to investigate the antioxidant status. Biochemical results showed that SOD and NRF-1 levels were significantly increased in the humic acid group (III) compared with the control group (II) while MDA levels were significantly decreased. On histopathological examination, cerebral edema, vacuolization, degeneration, and destruction of neural elements were decreased in the humic acid group (III) compared with the control group (II). Cerebral ischemia was attenuated by humic acid administration. These observations indicate that humic acid may have potential as a therapeutic agent in cerebral ischemia by preventing oxidative stress.

Purpose: To assess the relation between ankylosing spondylitis (AS) and degenerative disc disease emerging in association with various intrinsic and extrinsic factors and to evaluate the correlation between degree of degeneration in intervertebral discs and apparent diffusion coefficient (ADC) values., Methods: Thirty-five patients with AS and a control group of 35 patients were included in the study. Three hundred fifty intervertebral discs were assessed in terms of degeneration by analyzing signal intensities and morphologies on T2 weighted series of a 1.5 Tesla magnetic resonance scanner. ADC values were determined in diffusion weighted images (DWI) using a "b value of 500 s/mm(2)". Patients in the AS and control groups were compared in terms of intervertebral disc degeneration, and association between degree of degeneration and ADC values was analyzed., Results: The mean of total degeneration degrees for five lumbar intervertebral discs was significantly higher in the patients with AS compared to the control group (16.77±4.67 vs 13.00±4.08, respectively; P=0.001). When intervertebral discs were analyzed separately, disc degeneration was again significantly higher in patients with AS compared to the control group, with the exception of L5-S1. Age, cholesterol level, triglyceride level, duration of disease and BASFI index were significantly associated with degree of degeneration in patients with AS. A negative correlation was determined between disc degeneration and ADC value., Conclusion: AS is a risk factor for degenerative disc disease due to its systemic effects, the fact it leads to posture impairment and its inflammatory effects on the vertebrae. A decrease in ADC values is observed as degeneration worsens in degenerative disc disease.

Brain ischemia and treatment are one of the important topics in neurological science. Free oxygen radicals and inflammation formed after ischemia are accepted as the most important causes of damage. Currently, there are studies on many chemopreventive agents to prevent cerebral ischemia damage. Our aim is to research the preventive effect of the active ingredient in genistein, previously unstudied, on oxidative damage in cerebral ischemia. Rats were randomly divided into three groups: control group (no medication or surgical procedure), ischemia group, and artery ischemia+genistein group, sacrificed at 24 h after ischemia. The harvested brain tissue from the right hemisphere was investigated histopathologically and for tissue biochemistry. Superoxide dismutase and nuclear respiratory factor 1 values decreased after ischemia and they increased after genistein treatment, while increased malondialdehyde levels after ischemia reduced after treatment. Apoptosis-related cysteine peptidase caspase-3 and caspase-9 values increased after ischemia, but reduced after treatment. Our study revealed that genistein treatment in cerebral ischemia reduced oxidative stress and neuronal degeneration. We believe that genistein treatment may be an alternative treatment method.

Diagnosis, treatment, and surgery for lumbar disc herniations have existed for over a century. However, during the last three decades, there have been many new developments in imaging techniques, surgical procedures, physical medicine, and rehabilitation. In light of this, the most effective and appropriate treatment is controversial. Spontaneous regression of sequestrated, extruded, or protruded disc herniation has often been reported in the literature, although it is still a rare phenomenon. After a thorough review of the literature, we did not find any case report about this phenomenon after weight loss. In this report, though, we present a recent case about spontaneous regression of extruded disc herniation following weight loss.

Daidzein, a plant extract, has antioxidant activity. It is hypothesized, in this study, that daidzein exhibits neuroprotective effects on cerebral ischemia. Rat models of middle cerebral artery occlusion were intraperitoneally administered daidzein. Biochemical and immunohistochemical tests showed that superoxide dismutase and nuclear respiratory factor 1 expression levels in the brain tissue decreased after ischemia and they increased obviously after daidzein administration; malondialdehyde level and apoptosis-related cysteine peptidase caspase-3 and caspase-9 immunoreactivity in the brain tissue increased after ischemia and they decreased obviously after daidzein administration. Hematoxylin-eosin staining and luxol fast blue staining results showed that intraperitoneal administration of daidzein markedly alleviated neuronal damage in the ischemic brain tissue. These findings suggest that daidzein exhibits neuroprotective effects on ischemic brain tissue by decreasing oxygen free radical production, which validates the aforementioned hypothesis.

Aim: Anterior transodontoid screw fixation technique is generally chosen for the management of type II odontoid fractures. The nonunion of type II odontoid fractures is still a major problem especially in elderly and osteoporotic patients. Eleven osteoporotic type II odontoid fracured patients were presented in this article., Material and Methods: We have divided 11 patients in two groups as classical and Ozer's technique. We have also compared (radiologically and clinically) the classical anterior transodontoid screw fixation (group II: 6 cases) and Ozer's transodontoid screw fixation technique (group I: 5 cases) retrospectively., Results: There was no difference regaring the clinical features of the groups. However, the radiological results showed 100% fusion for Ozer's screw fixation technique and 83% fusion for the classical screw fixation technique., Conclusion: In conclusion, we suggest that Ozer's technique may help to increase the fusion capacity for osteoporotic type II odontoid fractures.

Background/aim: Brain ischemia and treatment are important topics in neurological science. Free oxygen radicals and inflammation formed after ischemia are accepted as the most significant causes of damage. Currently there are studies on many chemopreventive agents to prevent cerebral ischemia damage. Our aim is to research the preventive effect of the active ingredient in syringic acid, previously unstudied, on oxidative damage in cerebral ischemia., Materials and Methods: The rats were randomly divided into 4 groups: control group (no medication or surgical procedure), sham group (artery occlusion), artery occlusion + syringic acid group sacrificed at 6 h, and artery occlusion + syringic acid group sacrificed at 24 h. Obtained brain tissue from the right hemisphere was investigated histopathologically and for tissue biochemistry., Results: Superoxide dismutase and nuclear respiratory factor 1 values decreased after ischemia and they increased after syringic acid treatment, while increased malondialdehyde levels after ischemia were reduced after treatment. Caspase-3 and caspase-9 values increased after ischemia and decreased after treatment; this reduction was more pronounced at 24 h., Conclusion: Our study revealed that syringic acid treatment in cerebral ischemia reduced oxidative stress and neuronal degeneration. In the light of the biochemical and histopathologic results of the present study, we think that syringic acid treatment may be an alternative treatment method.

Objective: Many cancer patients treated with radiotherapy suffer severe side effects during and after their treatment. The aim of this study was to investigate the effects of irradiation and the addition of Nigella sativa oil (NSO) on the oxidant/antioxidant system in the liver tissue of irradiated rats., Methods: A total of 24 Sprague-Dawley rats were randomly distributed into three groups of equal numbers. The control group received neither NSO nor irradiation but received 1-ml saline orally. The irradiation group (IR) received total head 5 gray (Gy) of gamma irradiation as a single dose, plus 1-ml saline orally. The IR plus NSO group received both total head 5 Gy of gamma irradiation as a single dose and 1 g/kg/day NSO orally through an orogastric tube starting one hour before irradiation and continuing for 10 days., Results: While liver tissue total oxidant status (TOS), lipid hydroperoxide (LOOH) level, and oxidative stress index (OSI) were significantly increased in the IR group compared to the control group, total antioxidant status (TAS), sulfhydryl (-SH) levels, and PON activity were significantly decreased. Cp activity in the IR plus NSO and IR groups was higher than in the control group. ARYL activity in the IR plus NSO supplemented group was higher than that in other groups., Conclusions: NSO reduces oxidative stress markers and has antioxidant effects, which also augments the antioxidant capacity in the liver tissue of rats.

Purpose: To investigate the neuroprotective effects of Sulindac on the hippocampal complex after global cerebral ischemia/reperfusion (I/R) injury in rats., Methods: Thirty one Sprague-Dawley rats were used, distributed into group I (sham) n:7 were used as control. For group II (n:8), III (n:8) and IV (n:8) rats, cerebral ischemia was performed via the occlusion of bilateral internal carotid artery for 45 minutes and continued with reperfusion process. 0.3 mL/kg/h 0.9 % sodium chloride was infused intraperitoneally to the Group II rats before ischemia, 5μg/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group III rats before ischemia and 5μg/kg/h/0.3 ml sulindac was infused intraperitoneally to the Group IV rats after ischemia and before reperfusion process. The levels of MDA, GSH and MPO activity were measured in the left hippocampus tissue. The hippocampal tissue of all group members were taken for histopathological study., Results: The MDA and MPO levels increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05). Beside these, the GSH levels decreased from group I (control) to group II (I/R) (P<0.05) and increased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05).The number of apoptotic neurons increased from group I (control) to group II (I/R) (P<0.05) and decreased from group II (I/R) to group III (presulindac + I/R) and IV (postsulindac + I/R) (P<0.05)., Conclusion: The Sulindac may have neuroprotective effects on ischemic neural tissue to prevent the reperfusion injury after ischemia.

Vascular complications after lumbar discectomy are rarely seen. We present a unique and potentially life-threatening postoperative complication from this procedure. A 27-year-old man was admitted to our emergency vascular unit 1 day after a lumbar discectomy, during which a scalpel blade fragmented and a part was lost. Radiological images of the patient were performed and a broken scalpel blade was located anterior to the sacrum. An anterior laparotomy was performed which identified a mass within the left iliac vein that migrated suddenly to the inferior vena cava. An emergency angiography was performed, by which time the scalpel blade had ascended to the right-sided inferior pulmonary artery. It was subsequently removed via a right lateral thoracotomy.

Purpose: To investigate the clinical features, prognostic factors, and treatment outcome in early-stage cervical carcinoma patients treated with postoperative radiotherapy (RT)/radiochemotherapy (RCT)., Methods: The records of 256 Stage IB and II cervical cancer patients treated with postoperative RT/RCT from 1992-2007 were retrospectively reviewed. Median age of the patients was 47 (range: 25-78). Two hundred one (78.6%) patients had squamous cell carcinoma and 29 (11.3%) had adenocarcinoma. One hundred and eighty-seven (73.0%) had FIGO Stage IB and 69 (27%) had Stage II disease. Concomitant cisplatin-based chemotherapy was administered to 47 (18.4%) patients. Metastatic lymph node ratio (MLNR), defined as number of metastatic lymph nodes divided by the number of dissected lymph nodes, was 0 in 142 (55.5%) patients, from 1% to 10% in 27 (10.5%) and > 10% in 31 (12.1%) patients., Results: Median follow-up duration was 60.5 months (range: 6-202 months). Five-year locoregional control (LRC), disease-free survival (DFS), disease specific survival (DSS) and overall survival (OS) rates were 90.8%, 83.4%, 91.2%, and 85%, respectively. In multivariate analysis; bulky tumor (> 4 cm) was shown as an important prognostic factor for LRC, DFS and DSS. Pretreatment hemoglobin level (< 10 g/dl) was associated with lower OS rate. Endometrial involvement was associated with lower LRC and DFS. Treatment break > 14 days showed significance for DFS and DSS. MLNR was found as a valuable prognostic factor for all endpoints (LRC, DFS, DSS and OS). The rate of grade 3-4 late toxicity was 3.6% and 2%, respectively., Conclusion: Postoperative RT/RCT is an effective treatment modality for early-stage cervical cancer patients with unfavorable features and provides satisfactory local control and survival rates with low morbidity.

Aims and Background: To compare the antioxidant status of cervical cancer patients with healthy controls and to assess the antioxidant levels before and after radiotherapy or radiochemotherapy., Methods and Study Design: Antioxidant levels (glutathione, glutathione peroxidase, superoxide dismutase, and malondialdehyde) were measured in 35 patients with cervical cancer and 35 age-matched healthy controls. Blood samples were collected twice (before and after treatment) from cervical cancer patients and once from healthy control subjects., Results: In the patient group, pre-radiotherapy glutathione and glutathione peroxidase levels were significantly lower (P <0.01 and P <0.0001, respectively) than the control group. Pre-radiotherapy levels of superoxide dismutase were significantly higher in cancer patients (P <0.01). In general, no difference was observed between pre- and post-radiotherapy antioxidant levels in cancer patients. However, when post-radiotherapy glutathione levels were analyzed, patients who did not respond to treatment had significantly higher levels than those who did respond (P <0.01)., Conclusions: Levels of antioxidants significantly differed between the patients with cervical cancer and the controls, and no change in antioxidant levels was observed after treatment. Moreover, further studies evaluating the predictive value of glutathione levels on treatment response are warranted.

Purpose: To test the validity and reliability of The European Organization for Research and Treatment of Cancer (EORTC) core (QLQ-C30) and breast cancer module (QLQ-BR23) for Turkish breast cancer patients., Patients and Methods: A total of 127 patients treated with radiotherapy (RT) enrolled to this prospective study. EORTC QLQ-C30 and QLQ-BR23 modules applied to patients before initiation of RT and at follow-up period. Statistical analyses were performed by SPSS 13.0., Results: Questionnaires' were found reliable and valid for Turkish breast cancer patients. Six of the 8 multi-item scales of QLQ-C30 had a high reliability (Cronbach's ? >0.7); where physical functioning and pain scores were less reliable (Cronbach's ? of 0.66 and 0.68 respectively). In the QLQ-BR23, 3 of 5 multi-item scales were reliable; less reliable were breast and arm symptoms scale (Cronbach's ? of 0.65 and 0.61 respectively). In our analysis the most determinative subscales of QLQ-C30 on global health was emotional functioning followed by fatigue, role functioning and appetite loss (respectively p=0.002, p=0.01; p=0.03 and p=0.08). Among QLQ-BR23 scales systemic therapy SIDE effects, future perspective and upset by hair loss subscales had high impact on global health status (respectively p=0.006; p=0.01 and p=0.03)., Conclusions: The Turkish version of EORTC QLQ-C30 and QLQ-BR23 modules are reliable and valid tools to assess quality of life of Turkish breast cancer patients.

Ovarian cancer which is the most common cause of death among all gynecological malignancies tends to metastasize through peritoneal cavity. Skin metastasis, however, is a very rare clinical entity and related with poor prognosis. We report a 43-year-old patient with recurrent ovarian cancer presented with extensive abdominal skin metastasis approximately 6 years after the initial diagnosis. Patient was treated with radiotherapy with electrons to a total dose of 37.5 Gy given in 2.5 Gy per fraction per day. Skin metastasis showed good response to radiotherapy, and the patient has been alive for 7 months after radiotherapy with no recurrences on abdominal skin. Radiotherapy might be considered as an efficient palliative treatment option for the skin metastasis of ovarian cancer.

Burnout is an important occupational problem for health care workers. We aimed to assess the burnout levels among oncology employees and to evaluate the sociodemographic and occupational factors contributing to burnout levels. The Maslach Burnout Inventory, which is designed to measure the three stages of burnout-emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA), was used. The study sample consisted of 90 participants with a median age of 34 (range 23-56). The mean levels of burnout in EE, DP and PA stages were 23.80 +/- 10.98, 5.21 +/- 4.99, and 36.23 +/- 8.05, respectively, for the entire sample. Among the 90 participants, 42, 20, and 35.6% of the employees had high levels of burnout in the EE, DP, and PA substage, respectively. Sociodemographic and occupational factors associated with higher levels of burnout included age of less than 35, being unmarried, being childless, >40 work hours per week, working on night shifts, and <10 years experience in the medicine/oncology field. Within all oncology clinics, medical oncology employees had the highest levels of burnout. Furthermore, employees who are not pleased with working in oncology field, who would like to change their specialty if they have an opportunity, and whose family and social lives have been negatively affected by their work experienced higher levels of burnout. Burnout syndrome may influence physical and mental health of the employee and affects the quality of health care as well. Therefore, several individual or organizational efforts should be considered for dealing with burnout.

Purpose: To evaluate the necessity and direct cost effectiveness of screening and staging procedures in breast cancer patients having ≥4 positive axillary lymph nodes and to identify further possible biopathological risk factors associated with increased risk of metastasis., Methods: We reviewed the demographic and clinicopathological data from the medical records of 1897 newly diagnosed breast cancer patients. Patients having ≥4 positive axillary lymph nodes after primary surgery for breast cancer and who had staging examinations for metastasis were eligible. The impact of staging procedures (thoracoabdominal CT, bone scan etc.) for detecting metastasis, decision of adjuvant treatment and direct costs were analyzed in 329 patients with operable breast cancer., Results: Thirty-five (10.6%) patients were found with metastasis at diagnosis. Seven (20.0%) among them had multiple metastases. Eighteen (51.4%) had lung, 17 (48.6%) bone, and 7 (20.0%) liver metastasis. Twenty-one (60.0%) patients needed further radiological investigation for metastasis confirmation. Treatment decision was changed in 27 (77.1%) patients. No statistically significant risk factor was identified among the metastatic patients by means of conventional demographic and biopathological parameters. The cost of screening was lower when compared to the cost of treatment without any screening procedure., Conclusion: Since the conventional clinicopathological data seems not sufficient to define the risk of developing metastasis in breast cancer patients with ≥4 axillary lymph node involvement, all of them should undergo full staging examinations until new parameters based on genomic level are defined. Staging procedures need modification for high risk breast cancer patients.

Purpose: To determine the prognostic factors related to local control and survival in 257 patients with uterine cervical cancer treated with definitive radiotherapy (RT)., Materials and Methods: The medical records of 257 patients treated with definitive RT from January 1987 to December 1998 were reviewed retrospectively. Pretreatment and treatment parameters were analyzed to determine their prognostic value onlocal control and survival. Survival analyses were performed using the Kaplan-Meier method. The log-rank test was used for univariate analyses and the Cox regression model was used for multivariate analyses., Results: Median age was 55 (range 25-82). Squamous cell carcinoma was the most common histologic type (89.1%). The distribution per FIGO Stage was IIA: 13.2%; IIB: 54.9%; IIIA: 3.9%; IIIB: 19.8%; IVA: 8.2%. Ninety-eight patients (38.1%) were treated with external RT alone; 134 (52.1%) received both external RT and intracavitary brachytherapy; 21 (8.2%) received external RT and chemotherapy and four (1.6%) received external RT, intracavitary brachytherapy and chemotherapy. Median follow-up duration was 50 months (range 24-155 months). The failure rate was 51.8% with 26.5% of patients having only local failure, 16.7% only distant failure and 8.6% both local and distant failure. Five-year local progression-free, disease-free and overall survival rates were 58.1%, 44% and 63.7%, respectively. In univariate analysis the prognostic factors identified for local progression-free survival were histology (p = 0.008), FIGO stage (p < 0.001), initial hemoglobin (Hgb) level (p = 0.001), total radiation dose (p = 0.039), use of brachytherapy (p = 0.001) and of chemotherapy (p = 0.037) and enlarged paraaortic nodes (p = 0.016). In multivariate analysis the prognostic factors were FIGO stage (p = 0.014), initial Hgb level (p = 0.040), and use of brachytherapy (p = 0.013). The prognostic factors identified for disease-free survival were histology (p = 0.011), FIGO stage (p < 0.001), initial Hgb level (p < 0.001), use of brachytherapy (p = 0.001) and of chemotherapy (p = 0.014) in univariate analysis; and FIGO stage (p < 0.001), initial Hgb level (p = 0.017), total tumor dose (p = 0.034), use of brachytherapy (p = 0.006) and of chemotherapy (p = 0.021) in multivariate analysis. Factors influencing overall survival were FIGO stage (p < 0.001), initial Hgb level (p = 0.006), overall treatment time (p = 0.028), total tumor dose (p = 0.007), use of brachytherapy (p < 0.001), enlarged paraaortic (p < 0.001) and pelvic nodes (p = 0.004) in univariate analysis; and FIGO stage (p < 0.001), overall treatment time (p = 0.031), enlarged paraaortic (p = 0.007) and pelvic lymph nodes (p = 0.043) in multivariate analysis., Conclusion: Definitive RT is an effective treatment for patients with uterine cervical cancer. There are many prognostic factors influencing treatment outcome. Brachytherapy and chemotherapy must be added in appropriate patients to improve the outcome. Future prospective trials should be undertaken to confirm the validity of these factors and to individualize the treatment strategy for every patient.

Between March 1992 and February 1993, hyperfractionated radiotherapy (HRT) (1.2 Gy.fraction-1, twice a day, total dosage of 69.6 Gy) and simultaneous cisplatin (70 mg.m-2, 3rd and 23rd days of HRT) and etoposide (70 mg.m-2, 1-3rd and 20-23rd days of HRT) were applied to 27 patients with inoperable non-small cell lung cancer (NSCLC). Their Karnofsky performance statuses were 70-90%, and mean age was 52 (36-63). Two cases were stage II (one of the patients refused the operation and the other was medically inoperable because of insufficient ventilation), eight were stage IIIA and 17 were stage IIIB. No severe life-threatening grade IV acute toxicity findings were observed. Generally, acute side-effects were transient and did not require discontinuation of treatment. Tumour responses were as follows: complete response in six cases (23%); partial response in 19 cases (70%); and stable disease in two (7%). When complete response rates were compared according to stage, histological type, age group and weight loss, no statistically significant difference was found. Median overall and disease-free survival times were 14 months (95% confidence interval) (95% CI) 11-17 months and 10 months (95% CI 7-13 months), respectively. Twelve and 24 months overall and disease-free survival rates were 56 and 30%, and 36 and 24% respectively. No statistically significant difference was found in overall survival rates among epidermoid and nonepidermoid types, while the difference in disease-free survival was statistically significant. The acute and late complications of our HRT and simultaneous chemotherapy protocol were tolerable and the survival rates were encouraging.
