Abstract
PURPOSE Early childhood epilepsy presents a significant challenge, with approximately 30 % of individuals experiencing treatment failure. This study aimed to identify predictors of medical intractability in children with epilepsy onset during the first two years of life, excluding infantile epileptic spasm syndrome. METHODS A total of 323 children were retrospectively evaluated. The analyses included a review of medical records for demographic, laboratory, radiological, and electroencephalographic (EEG) findings. Children were diagnosed with drug-resistant epilepsy (DRE) according to the ILAE diagnostic criteria. Twenty-one potential prognostic predictors were examined in relation to medical intractability. RESULTS Among the 323 children (56.7 % male), 119 (36.8 %) had unknown epilepsy, 131 (40.6 %) had structural epilepsy, 53 (16.4 %) had genetic epilepsy, and 20 (6.2 %) had metabolic epilepsy. Over a median follow-up of 68 months, 55.4 % of the children achieved ≥6 months of seizure freedom, 33.1 % developed DRE, and the remaining 11.5 % had rare ongoing seizures but did not meet the criteria for DRE because they were only treated with one antiseizure medication at the last follow-up. Univariate logistic regression analyses identified ten risk factors significantly associated with DRE. Multivariate logistic regression analyses revealed that the presence of developmental delay at epilepsy onset (p = 0.000; OR 7.890; 95 %CI 2.713 to 22.945), history of status epilepticus (p = 0.000; OR 8.247; 95 %CI 3.619 to 18.793), number of antiseizure medications (ASMs) at the sixth month of diagnosis (p = 0.000; OR 20.585; 95 %CI 8.993 to 47.117), and initial EEG findings (p = 0.046; OR 2.366; 95 %CI 1.015 to 5.518) were predictors of medical intractability. Nineteen (5.9 %) children died during follow-up for various reasons, including progressive neurogenetic or neurodegenerative disorders. CONCLUSION Developmental delay at epilepsy onset, a history of status epilepticus, the use of two or more ASMs in the sixth month of diagnosis, and abnormal initial EEG findings were associated with medical intractability.

Abstract
OBJECTIVE The purpose of this prospective study was to determine the conditions under which intra-articular injection therapy may be superior to nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with sacroiliac joint pain in the outpatient setting at our hospital. PATIENTS AND METHODS Patients with sacroiliac pain were divided into two groups: NSAID and the sacroiliac injection group. The NSAID group received 25 mg of indometacin orally once a day and 750 mg of naproxen orally once a day. In the sacroiliac injection group, 5 mg of betamethasone were injected into the sacroiliac joint. The patients' history of lumbar surgery, whether they had sacroiliitis, and the duration of pain were recorded. The patients' VAS (Visual analogue scale) scores at week 1 and month 1 were evaluated. RESULTS VAS scores were decreased after the first week and first month in the sacroiliac injection group compared to the NSAID group (p<0.001). Sacroiliac steroid injection was found to be superior to NSAIDs in reducing VAS scores in patients with sacroiliitis, a history of lumbar surgery, and pain lasting more than 30 days (p<0.001). In patients without sacroiliitis, without a history of lumbar surgery, and with less than 30 days of pain, no difference was observed between the groups in reducing VAS scores at the end of the first month. CONCLUSIONS In patients with sacroiliac joint pain, sacroiliac joint injection is superior to NSAIDs in pain relief in patients with pain for more than 30 days, those with MRI-diagnosed sacroiliitis, and those who have undergone lumbar surgery.

Abstract
OBJECTIVE Stereotactic radiosurgery is a therapeutic modality for cavernomas that is associated with certain adverse effects, such as perilesional edema. In this study, we aimed to estimate the presentation of perilesional edema using imaging techniques, considering its location, proximity to major venous and arterial structures, size, depth, and eloquent location. PATIENTS AND METHODS The radiographic evaluation included their sizes, localization of the lobes, whether they were in the deep or superficial regions, eloquent areas, and their proximity to the major arteries and venous sinuses. RESULTS As the size increased, the time to edema increased at the same rate (r=0.972, p=0.001). We determined that the duration of edema increases as it attaches to the great venous structures, and edema occurs over a longer time (r=-0.761, p=0.001). Cavernomas >13 mm had a high probability of causing edema (p=0.0014). Edema occurred with a high probability in patients with an arterial distance <5.69 mm and a venous/arterial distance ratio >8.93 (specificity 100%, selectivity 98.2%). CONCLUSIONS When recommending stereostatic radiosurgery treatment, the possibility of edema formation should be calculated based on the location, size, and proximity of the cavernoma to the vascular structures, and the choice of treatment should be made accordingly.

Abstract
OBJECTIVE Physical therapy and rehabilitation may improve low back pain and quality of life after lumbar disc herniation. However, there is no agreement on its optimal start time and rehabilitative methods. This study evaluates the effects of early and late rehabilitation on low back pain and quality of life following unilateral microdiscectomy. PATIENTS AND METHODS A total of 204 patients who underwent surgery for lumbar disc herniation were included and subsequently randomized into five groups: 1. No exercise, 2. The 2nd-week walking group, 3. 1st-month walking group, 4. 2nd-week waist exercise, 5. 1st-month waist exercise. Visual analog scale (VAS) and Oswestry Disability Index (ODI) were assessed at the 1st week, 1st, 3rd, and 6th, and 12th-month follow-up after surgery. RESULTS 1st-month VAS scores were analyzed, and a significant difference was found between the VAS scores of the 2nd-week walk (3.60±0.78) and 2nd-week waist exercise (3.38±0.67) groups and the other groups (p<0.001). 3rd-month VAS results were analyzed, and the VAS scores of the 1st-month walk group (2.67±0.48) were significantly higher than those of the 2nd-week walk group (1.73±0.45) (p<0.001). A significant difference was observed between the no-exercise group (2.93±0.91) and the other groups according to the 12-month VAS scores, with the VAS scores of the no-exercise group being significantly higher than the other groups (p<0.001). There was a significant difference between the ODI scores of both the 2nd-week walk (38±8.55) and the 2nd-week waist (33.8±6.61) exercise groups and the other groups according to the 1st-month ODI scores (p<0.001). A significant difference was observed between the no-exercise group (35.2±8.25) and the other groups according to the 12-month ODI scores, and the ODI scores of the no-exercise group were significantly higher than the other groups (p<0.001). CONCLUSIONS Regular exercise is highly recommended for long-term pain relief, as well as for achieving a speedy recovery after surgery, which is crucial to maintaining a high quality of life and preventing loss of earning potential. We believe that early implementation of exercises is ideal, but even if initiated later, standard back exercises can still expedite rehabilitation.

Abstract
OBJECTIVE The neutrophil-to-lymphocyte ratio (NLR) is used for the prognosis of diseases characterized by inflammatory processes. This study aims to discuss the long-term outcomes and NLR in pediatric traumatic brain injury cases. PATIENTS AND METHODS This study investigated traumatic brain injury patients younger than 18 years. Patients were grouped into 5 groups according to their Glasgow outcome scores (GOS). Initial admission Glasgow coma scale (GCS) values, neurological examinations, pupil conditions, cardiopulmonary resuscitation (CPR) administration, and seizure occurrence were recorded. Neutrophil counts and lymphocyte counts, derived from complete blood count (CBC) values taken during the patient's first 8 hours of admission, were used to calculate the NLR value. RESULTS A total of 150 patients, 54 (36%) females and 96 (64%) males, were assessed in the study. The most frequent accident type was falling from a height [84 patients (56%)]. The GCS, CPR, pupillary reflex, anisocoria, surgical procedure, and neutrophil counts were significantly different between the GOS scores. There was no statistically significant difference between the GOS and the NLR (p=0.400). There was a significant difference in NLR value according to CPR, seizures, and brain injury type (p<0.05). CONCLUSIONS NLR values are not correlated with 1-year outcome scores in pediatric traumatic brain injury patients, unlike proven parameters such as initial GCS scores and neurological status.

Abstract
Epithelioid hemangioendothelioma is a rare mesenchymal tumor of vascular endothelial origin. Non-soft tissue epithelioid hemangioendothelioma can also be seen in different organs. Although chemotherapy has been used in some patients, complete surgical removal of the tumor tissue has proven to be the most durable solution. A 15-year-old female patient was admitted to our institution with right arm and neck pain. The patient complained of numbness and weakness in the right hand. Computerized tomography indicated an expansile lesion exhibiting osteolytic features located predominantly on the right side of the corpus, pedicle, lamina, and lateral processes of the C7-T1 vertebra. The patient underwent a surgical procedure involving the application of a bilateral C4-5-6 lateral mass screw, left C7-T1 pedicle screw, and bilateral T2-3 pedicle screw and fusion. The complete residual neoplasm was surgically removed during the procedure. Due to the rarity of epithelioid hemangioendothelioma, the existing literature on this topic is confined to case reports, supplemented by a small number of retrospective descriptive case series that aimed to improve our understanding of the clinical, pathological, and molecular features of the condition, as well as to guide potential treatment strategies.

Abstract
BACKGROUND/AIM Compound or open depressed fractures (CDF) is one of the urgent operations of neurosurgery, as it can result in complications of infection. This study is reported to investigate the effect of topical vancomycin powder to the infection rates in the compound depressed skull fractures which have been operated on. MATERIALS AND METHODS This present study was conducted on 46 cases with compound depressed skull fractures which have been operated on. Cases were divided into two groups according to the use of subgaleal topical vancomycin powder during the operation. The preoperative and postoperative CRP levels, localization of the fracture, hospitalization time, operation length, dural injury, pneumocephalus, and mortality rates have been examined. RESULTS In cases with dural injury and pneumocephalus, a statistically significant relationship was found between the use of topical vancomycin powder and the frequency of post-op infection (p < 0.001). It was observed that the incidence of postoperative infection was significantly higher in 12 (85.7%) cases with pneumocephalus and dural injury when vancomycin powder was not used. Also, it was observed that the post-operative infection level was significantly higher in fractures in the frontal and parietal regions without vancomycin powder(p < 0.05). CONCLUSIONS The use of subgaleal topical vancomycin powder is an option to reduce the infection rates and mortality, especially in the cases of compound depressed fractures, which is considered as a dirty wound and prone to infection. It is especially recommended in the presence of dural injury and pneumocephalus.

Abstract
OBJECTIVE In this randomized and prospective research, we aimed to relieve surgical and muscle-related pain early after lumbar disc operations with caudal preemptive analgesia. MATERIALS AND METHODS A total of 120 patients with single-level lumbar disc herniation were included in this study. The caudal epidural injection was performed for all patients 20 min before surgery. The patients were divided into three groups. Non-steroidal anti-inflammatory drugs or tramadol use were recorded. Pre-operative and post-operative pain was interpreted through a visual analog scale. RESULTS There was a difference between the groups in all post-operative measurements (p < 0.05), between Group 1 and Group 3, and between Group 2 and Group 3. A statistical significance has been achieved between the groups at the 1st h, 2nd h, 4th h, and 24th h (p < 0.05). The difference between the pain intensities of the patients at the 24th h and the 1st week was statistically significant in Groups 1 and 2 (p < 0.05). Evaluation of the effects of medical treatments reduced the severity of back pain and foot pain. CONCLUSION The preemptive bupivacaine or in combination with methylprednisolone caudal injection is an effective and safe method to reduce post-operative pain and ameliorate functional capacity for the treatment of lumbar disc herniation.

Abstract
Background This study aimed to investigate the effects of omega-3 fatty acid use on sepsis and mortality in patients treated for COVİD-19 disease in the intensive care unit (ICU) based on clinical and laboratory results. Aim To determine the effect of omega-3 fatty acid use on sepsis and mortality in patients with COVİD-19. Patients and Methods A total of 80 patients with confirmed COVİD-19 infection who were hospitalized in the ICU of Ankara City Hospital, received (n = 40) or did not receive (n = 40) omega-3 fatty acid dietary supplementation, were included in this single-center, retrospective study. The clinical and laboratory data of eligible patients were extracted from the hospital records. Results The mean age was 65.5 (13.6). The mean length of stay in the intensive care unit was 11.5 (6.3) days. Mortality and sepsis development rates were similar in the groups. The frequency of patients who received pulse steroid therapy was higher in the group of patients who did not receive omega-3 (P < 0.05). Hypertension was more common in the patient group receiving omega-3 supplements (P < 0.05). Mean procalcitonin and interleukin-6 (IL-6) levels were significantly lower in patients who received omega-3 supplements compared to those who did not receive supplements (P < 0.001 and P < 0.05). Mean prothrombin time (PT) was shorter in patients receiving omega-3 supplementation (P < 0.05). Conclusions Study results obtained in this study indicate that providing omega-3 fatty acid supplements may be beneficial to patients with severe COVİD-19, however further research with large-scale randomized controlled trials is necessary.

Abstract
BACKGROUND/AIM Sleep deprivation may lead to individual and social insufficiency associated with many physiological and psychological pathologies. This study is reported to investigate sleep quality and the relationship between treatment modalities of lumbar disc herniation, which is the most common cause of chronic lower back pain and sciatica. MATERIALS AND METHODS This present study was conducted on 249 cases with chronic lower back pain and sciatica caused by a single- level lumbar disc herniation diagnosed after lumbar MRI (Magnetic Resonance Imaging) between June 2017 and September 2019. Cases were divided into three groups according to the treatment modalities: early surgical treatment (n:80), extended conservative treatment (n:142), and medical treatment only (n:27). VAS (Visual Analog Scale) and PSQI (Pittsburgh Sleep Quality Index) data before the treatment and 6 months after the treatment were statistically analyzed. RESULTS It was determined that post-treatment VAS and PSQI scores were significantly reduced in all cases, regardless of the differences in treatment modalities (p < 0.05). In the early surgical treatment group, VAS score was improved by 69% and PSQI score was improved by 63.8%. These values were 28.5% and 38.6% in the extended conservative treatment. However, VAS score was increased by 27% in the patients who received only medical treatment. Statistical analysis of the treatment modalities showed that early surgical treatment was superior to the other treatment modalities (p < 0.05). CONCLUSIONS It was determined that early surgical treatment of lumbar disc herniation was superior to other treatment methods in terms of maintaining the sleep quality impairments associated with deterioration in sleep quality.

Abstract
Background Despite successful septoplasty surgery, some patients still complain of nasal obstruction (NO). Aim Our aim in the present study is to determine whether preoperative computed tomographic (CT) parameters have prognostic significance for the success of septoplasty. Material and Methods Retrospective data from 61 patients in a secondary care hospital who had undergone septoplasty met the inclusion and exclusion criteria. The effects of demographic and preoperative CT parameters (internal nasal valve [INV], external nasal valve area, angle of septal deviation, choana area, aperture pyriformis area, high septal deviation [HSD], transverse diameter of midnose, anterior/posterior deviation, concha and meatus diameter [superior, middle, inferior]) were studied in relation to the change in NOSE scores and the success of surgery. Results Of the 61 patients studied, 31 were male (51%) aged 18-55 years with a mean age ± SD (26.59 ± 9.41). It was found that the changes in NOSE scores were significantly different from each other (P < 0.01). Male gender, trauma history, moderate septal deviation, HSD, mucosal pathology, posterior deviation, bullous turbinate (right and left middle, right superior), and in the absence of allergy, paradoxical turbinate (right and left middle and superior), S-shaped deviation were found to have a significant correlation in the change of NOSE scores (P < 0.05). Age and internal valve differed with respect to outcome (P < 0.05). Variables in multiple linear regresion models of all parameters were found to be insignificant (P < 0.05). Conclusion Preoperative CT parameters are informative, but do not predict the postoperative success of septoplasty.

Abstract
Intratumoral hemorrhage/apoplexy in clival chordomas is extremely uncommon, with only 16 reported cases. The average age of patients was 46.2 years and slightly more than half were men. In cases published before 1990, all patients died from their disease without any intervention. Since then, 11 patients have undergone resection by a variety of approaches and there have been no deaths. The diagnosis of skull base chordomas relies on a combination of clinical presentation and radiographic features related to the location and invasion of the tumor. Chordomas presenting with sudden-onset symptoms should alarm the surgeon of a possible hemorrhage. As an illustration of this presentation, we describe a 58-year-old woman who presented with acute-onset headache and cranial nerve deficits. Computed tomography and magnetic resonance imaging demonstrated a hemorrhagic clival lesion with cavernous sinus extension. The patient underwent transsphenoidal resection of the lesion that resulted in the resolution of her symptoms. Histopathological evaluation of the lesion was consistent with chordoma with acute hemorrhagic components. Although intratumoral hemorrhage is rarely detected in chordomas, it should be considered a differential diagnosis of such lesions because prompt recognition and treatment are critical for patient survival.

Abstract
Context Estimation of intensive care unit (ICU) length of stay time (LOS) may be challenging, and pro-inflammatory cytokines can be used as a marker for this purpose. Objective The current study aimed to investigate the association between pro-inflammatory cytokine levels and LOS in hyperglycemic patients admitted to adult ICU. Design This is a prospective observational study. Subjects and Methods All adult ICU patients with a blood glucose level higher than 250 mg/dL, during the study period were included. Hospitalization day demographics were recorded, and plasma IL-6, IL1-ß, and TNF-α concentrations were measured. Results A total of 74 patients were enrolled in the study. Diabetic ketoacidosis (DKA) was positive in 31 patients, and the remaining 43 were in the non-DKA (NDKA) group. There was no difference between the two groups in terms of age, gender, LOS, hemoglobin, hematocrit, lactate levels, and platelets count. IL-6, IL-1ß, and TNF-α levels did not show any difference between DKA and NDKA groups (p=0.784, 0.413, and 0.288, respectively). There was a positive correlation between IL-6 levels and LOS (n=74, Pearson correlation=0.330; p=0.004). Conclusions Among pro-inflammatory cytokines, IL-6 showed a better performance for the prediction of LOS than IL-1ß, TNF-α, and CRP.

Abstract
AIM This study aims to compare the protective effects of ambrisentan, a selective endothelin typeA receptor antagonist, and bosentan, a dual endothelin typeA/B receptor antagonist, on experimental renal ischemia reperfusion injury. METHOD The study sample consisted of 21 female rats, which were divided into 3 groups: Control, Ambrisentan and Bosentan. For the ischemia-reperfusion injury model, left‑kidney nephrectomy was performed after sacrificing the animals. In the immunohistochemical examination, caspase-3 was examined, and then the apoptotic index was determined. In the biochemical examination, the activities of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase, and the levels of nitrite (NOx), TNF-α, and IL-1β were determined. RESULTS There were statistically significant differences between the groups in terms of total injury score grade in range of 0‒3 (p=0.001).The glomerular and tubular apoptotic indices were higher in the control group as compared to those of the ambrisentan and bosentan groups (p=0.001).There were no statistically significant differences in terms of SOD, CAT, GPx, MDA, IL-1β and TNF-α measurements among the groups (p>0.05). CONCLUSIONS In the experimentally created renal ischemia reperfusion model, both ambrisentan and bosentan increased the NOx level, decreased the apoptosis, and protected the kidney from renal ischemia reperfusion injury. However, no significant superiority was found between ambrisentan and bosentan in terms of their protective effects (Tab. 3, Fig. 2, Ref. 31).

Abstract
MATERIALS AND METHODS We present a 41-year old male patient who was admitted to our clinic with epileptic seizures, headaches and hemiparesis 14 months after SRS treatment for a left fronto-parietal Spetzler-Martin Grade III arteriovenous malformation (AVM). On his first-year follow-up perilesional edema was observed for which the patient received steroid treatment, but the patient did not show any benefit from it. In the cases of steroid resistant perilesional edemas, bevacizumab can be used for reducing symptoms and even radiological perilesional edema as well. RESULTS In our case, we have seen the effect of bevacizumab for symptomatic perilesional edema in a AVM patient after SRS treatment after radiological / neurological recovery. Our patient's headaches decreased rapidly after 2 days after treatment and was able to mobilize himself after 2 months but total resolution of symptoms and radiological findings observed after 1,5 years. CONCLUSIONS The duration and optimum dose of bevacizumab therapy needed to further investigation. Our study showed that bevacizumab was a long-term and effective treatment option for the cases with peritumoral edema resistant to glucocorticoid treatment, where the patient had conditions such as severe headache and neurological deficits.

Calvarial bone defects in ovariectomised rats treated with mesenchymal stem cells and demineralised freeze-dried bone allografts. Folia Morphol (Warsz) 2020; 79:720-735. [PMID: 31930468 DOI: 10.5603/fm.a2020.0001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 12/13/2019] [Accepted: 12/14/2019] [Indexed: 11/25/2022]
Abstract
BACKGROUND The aim of the study was to investigate the ability of a combination of bone marrow mesenchymal stem cells (BM-MSCs) with and without demineralised freeze-dried bone allografts (DFDBAs) to induce bone regeneration in calvarial defects in ovariectomised rats. MATERIALS AND METHODS Critical size defects were filled with a combination of DFDBAs and BM-MSCs or BM-MSCs alone. Eight weeks after calvarial surgery, the rats were sacrificed. The samples were analysed histologically and immunohistochemically. RESULTS No difference was observed in vascularisation between groups C1 (animals with cranial defect only, control group) and O1 (animals with cranial defect only, ovariectomy group). Intramembranous ossification was observed at a limited level in groups C2 (animals with cranial defect with MSCs, control group) and O2 (animals with cranial defect with MSCs, ovariectomy group) compared to C1 and O1. In group C3 (animals with DFDBAs with MSCs, control group), the fibrous structures of the matrix became compact as a result of a bone graft having been placed in the cavity, but in group O3 (animals with DFDBAs with MSCs, ovariectomy group), the fibrous tissue was poorly distributed between the bone grafts for the most parts. CONCLUSIONS We conclude that the insertion of BM-MSCs enhances bone healing; however, the DFDBA/BM-MSC combination has little effect on overcoming impaired bone formation in ovariectomised rats.

Abstract
BACKGROUND Internal auditory canal (IAC) lipomas are rare intracranial lesions. Consequently, preoperative imaging is essential in differentiating IAC lipomas from more common tumors such as vestibular schwannomas. The hallmark of lipomas on magnetic resonance imaging (MRI) is hyperintensity on T1-weighted images that suppresses on fat-suppressed sequences and does not enhance with gadolinium administration. CASE DESCRIPTION The present case describes a 53-year-old woman who was misdiagnosed with a vestibular schwannoma because of the lack of appropriate MRI sequences. CONCLUSIONS This case demonstrates the importance of ensuring that both fat-suppressed and non-fat-suppressed T1-weighted pregadolinium images are obtained in the diagnostic process of IAC lesions. It is therefore recommended that imaging centers ensure that such sequences are included in their MRI protocols.

Abstract
OBJECTIVE We aimed to evaluate the relationship between neutrophil lymphocyte ratio and the most common bacterial urinary tract infections after transplantation. We also assessed the frequency of bacterial infections, e.g. Escherichia coli, Klebsiella, and Enterococcus in the urinary tract, and determined the important factors affecting neutrophil/lymphocyte ratio (N/L). METHODS We compared the percentage of neutrophils (NE%), percentage of lymphocytes (Lym%), and N/L, along with blood urea nitrogen (BUN), creatinine, and white blood cells (WBC) in all patients before and after renal transplantation. RESULTS The Lym% and WBC significantly increased after surgery while N/L%, BUN, and creatinine levels were significantly decreased. Postoperative infections were evaluated by measuring WBC, NE%, Lym%, N/L%, serum urea and creatinine levels, and no significant differences were seen compared to the preoperative values. Univariate analysis also did not show any significant differences between pre- and post-operative parameters. However, a significant difference in N/L% ratio was seen between the E. coli infected and uninfected recipients. CONCLUSIONS Any significant difference in NE%, Lym%, and N/L%, BUN, creatinine, and WBC parameters among infected and non-infected renal transplant patients were not found. The steps should be taken to prevent pre-transplantation infection and patients should be continuously monitored for infections post-transplantation (Tab. 6, Fig. 1, Ref. 24).

Abstract
Ewing's sarcoma (EWS) is the second most common primary bone tumor seen in children and adolescents, first being osteosarcoma. Skull lesions are seen in 6 to 9% of cases. The tumor tends to reside most frequently on frontal and parietal bones. In the literature, majority of papers on calvarial EWS present cases with intracranial involvement; extracranial extension is reported in only eight cases. The case that we are presenting in this report is a 23-year-old male patient with multiple infiltrations in femur, costal bones, and calvarium which had been diagnosed radiologically and histopathologically as EWS. The calvarial metastasis had reached a very huge size with dimensions of approximately 7.5 × 7.5 × 9.5 cm and was successfully excised totally. Twelve months of follow-up revealed no recurrence in the surgical site showing that total removal of giant cranial EWS may improve morbidity of these patients.

Abstract
Aim Using AutoCAD, we examined the microleakage of dye at the edges of primary-teeth restorations using three glass ionomer-based restorative materials. Materials and Methods A total of 30 extracted noncarious primary molars were used. Class V cavities were adjusted on the buccal surfaces. The teeth were randomly divided into three groups of 10 teeth each as follows: Group A (Ketac Molar), Group B (Photac Fil), and Group C (Dyract XP). All specimens were stored for 24 h at 37°C in distilled water. The teeth were thermocycled 1000 times between 5°C ± 2°C and 55°C ± 2°C before immersion in 0.5% basic fuchsin for 24 h. Two mesiodistal cuts of each tooth were photographed under a stereomicroscope equipped with a digital camera. The dye-infiltrated surface area was measured. Statistical evaluations were performed by the Kolmogorov-Smirnov test, Levene test, one-way analysis of variance, and Tukey's honestly significant difference test. Results The mean microleakage ratio differed significantly among the groups (P < 0.05). Group C exhibited a significantly smaller area (P < 0.001) than the other groups. Group A had a nonsignificantly higher mean microleakage value than Group B (P > 0.05). Conclusions Polyacid-modified composite resin may be a useful restorative material in primary teeth in terms of minimizing microleakage.

Abstract
The aim of this study was to determine the changes in body mass index (BMI) of patients after renal transplantation regarding causes like steroid use, lower necessity for dietary restrictions, and changes in eating habits. Ninety-seven patients were enrolled in this retrospective study; they had undergone cadaver or living donor renal transplantation between 2011 and 2013. Demographic features of patients, height, weight, and BMI were evaluated before and 6 and 12 months after surgery. The patients were grouped as malnutritioned, normal, overweight, and obese. Statistical analyses were performed using the SPSS 11.0 statistics program. Mean age of patients was 39.1 ± 10.7 years. Twenty-six (26.8%) were female and 71 (73.1%) were male. Mean BMI before surgery was 22.52 ± 3.97 kg/m(2). Six months post-transplantation the mean BMI was 24.40 ± 4.1 kg/m(2) and after 12 months it was 25.56 ± 4.14 kg/m(2) (P < .05). Also, 68% of patients showed improvement 12 months after surgery; they were in the preoperative malnutrition group. There is a significant increase in the BMI of patients in the first year who undergo renal transplantation, and the reason is multifactorial. BMI is relevant to diabetes, hypertension, and allograft nephropathy. BMI should be carefully considered in the follow-up of patients who have undergone renal transplantation, and early nutritional changes with dietary and exercise programs should be performed in overweight cases.

Abstract
BACKGROUND AND OBJECTIVE Epidemiologic and clinical studies have indicated that diabetes is a risk factor for periodontal disease progression. The aim of the present study was to evaluate the morphological changes of gingiva in streptozotocin diabetic rats. MATERIAL AND METHODS 30 male Wistar rats that weighed 250-300 g were used in this study. The animals were randomly divided into 2 groups, one with streptozotocin-induced diabetes and another one with healthy (non-diabetic) animals. All rats were sacrificed after 21 days, and their maxillary first molars with surrounding tissues were observed morphological analyses. RESULTS In this study, it was observed that the epithelial thickness was greater in the diabetes group, compared to the control group. The statistical comparison of the diabetes and control groups for the thickness of each of the layers of the epithelium demonstrated that the thickness of the keratinized (corneum), granular and basal layers had significantly increased in the diabetic animals. Furthermore, the diabetes group displayed a decrease in the height of the connective tissue papillae, which was found to be statistically insignificant. Another important finding detected in the diabetes group was the congestion of the gingival capillaries, which showed that blood circulation is impaired in diabetes cases. CONCLUSION On the basis of the results obtained in this study, it was concluded that streptozotocin-induced diabetes may increase predisposition to periodontal disease by causing morphological changes in the periodontal tissues.

Abstract
INTRODUCTION Renal transplantation is the optimum treatment to improve the quality and length of life in end-stage renal disease. The aim of this study is to evaluate patients who underwent renal transplantation in our transplantation center and to present our clinical experience. METHODS Living donor and cadaveric renal transplants performed in the Transplantation Center of Sanko University Medical School between 2011 and 2014 were evaluated retrospectively. In our study, important parameters, such as delayed graft function, early and late phase infections and urologic complications after the operation, results of renal transplants with marginal donors with high creatinine levels, and increase in posttransplant body mass index were evaluated regarding to the living donor and cadaveric renal transplants performed in our transplantation center. RESULTS We included 136 patients were (92 males [68%] and 44 females [32%]), with an average age of 38.9 ± 9.8 years (range, 17-67). There were 63 living donor renal transplantations (43%) and 73 cadaveric renal transplantations (57%). The youngest cadaveric donor was 3 years old, and the oldest was 86. Fifteen of the cadaveric donors had blood creatinine levels around 1.5 g/dL. The highest level of creatinine from cadaveric donors was 5.1 g/dL. CONCLUSIONS Living donor renal transplantations have higher success rate than cadaveric renal transplantations. Ureteroneocystostomy and native ureteropyelostomy seem to be safe and efficient treatment methods for ureteral complications. High creatinine levels in marginal donors do not affect graft function in early stages.

Abstract
OBJECTIVE This study aimed to assess the prevalence of traumatic injuries of the primary incisors in preschool children from 2 to 5 years old in South-Eastern Anatolia, Turkey. Additionally, the relationship between traumatic dental injuries, parents' education level, family income, size of incisal overjet and the presence of anterior open bite were examined. BASIC RESEARCH DESIGN A cross-sectional survey CLINICAL SETTINGS Data were collected through oral examinations and structured interviews, and included socio-economic indicators. PARTICIPANTS A total of 727 children of both genders were included in the study. 122 of these children were aged 2; 183 aged 3; 178 aged 4 and 186 aged 5. RESULTS The prevalence of dental injuries was 8.0% (n = 58). The highest frequency of trauma in the primary teeth was observed at the age of 4. Boys experienced more dental injuries than girls, 12.2% and 4.0%, respectively. The most common crown fracture was in enamel only (57%) followed by crown fracture of enamel and dentin (19%). CONCLUSION The prevalence of dental injuries in Turkish preschool children was very low. The children with incisal overjet greater than 5mm and anterior open bite experienced more dental injuries in primary teeth than their counterparts with normal occlusion. Socio-economic indicators were not statistically significantly associated with the occurrence of traumatic dental injuries.

Abstract
Tortuous vasculature is a common reason for failure to stabilize a guiding catheter in an appropriate position and is associated with a higher incidence of vascular complications. In such a case, the guiding catheter often buckles into the aorta during an attempt to place the balloon or stent. In this report, we used the buddy wire technique to support the guiding catheter, and we passed through the vertebral artery origin stenosis with the help of a microcatheter-microguidewire combination which enabled stent deployment. We kept the buddy wire through the guiding catheter throughout the procedure and the 6F guiding catheter allowed passages of both buddy wire and stent system.

Abstract
OBJECTIVE To report an unusual case of Kimura's disease associated with intracranial hemorrhage, the first such report in the literature. CASE REPORT A 38-year-old man presented with chronic neurological disorders and a 10-year history of left cervical soft tissue swellings. Magnetic resonance imaging (MRI) of the cranium showed a subacute/chronic hematoma in the left occipitotemporal lobe and a chronic infarct in the right parietal lobe. Cervical computed tomography (CT) and MRI showed multiple masses on the left side of the neck and parotid gland. Histopathologic examination revealed lymphocyte and eosinophil infiltration, proliferation of hyalinated blood vessels, and interstitial fibrosis. Steroid therapy (2 mg/kg per day) was started and the lesions regressed partially. The masses and some enlarged regional lymph nodes were resected. CONCLUSIONS Intracranial hemorrhage can either be a coincidental finding or complication of Kimura's disease. MRI and CT are effective modalities in radiologic diagnosis of this condition.

Abstract
BACKGROUND Polyethylene fibre-reinforced composites (FRCs) have been under development for some time. However, there is a lack of data on the clinical performance of these restorations. The purpose of this descriptive study was to evaluate the clinical performance of endodontically treated anterior teeth restored using polyethylene FRCs. METHODS Eighty-seven endodontically treated anterior teeth in 65 patients were restored with polyethylene FRCs. The restorations were placed by three operators. The patients were recalled for examinations every year for up to three years. The restorations were evaluated using modified Ryge and USPHS criteria. RESULTS A statistical analysis showed no significant difference in marginal irregularity, marginal discolouration, surface texture, wear/anatomic form, fracture and retention, radiographic appearance, or debonding between the baseline and three-year results. CONCLUSIONS Based on our three-year examination results, polyethylene FRC restorations appear to be clinically successful.

Abstract
The objective of this study was to investigate the effects of ascorbic acid on the toxicity of cypermethrin's on histopathological lesions in tissues and protein, glycogen levels in Oreochromis niloticus. Nile tilapia was exposed to 0.22 and 0.44 μg/l cypermethrin+control diet, 0.22 and 0.44 μg/l cypermethrin+ascorbic acid supplemented diet for 20 days. The fish were allowed recuperation period of 15 days in pesticide-free water and fed with ascorbic acid suplementation diet. In light microscopic investigation, histopathological lesions were observed in the gill, liver and kidney. The severity of lesions accreted depending on increased pesticide concentration and control diet. Some of the lesions were reversible or at least were less pronounced after recuperation period. Protein levels decreased in some groups after treatment period according to control groups (p<0.05). The highest depletions in liver, muscle and gill protein levels were found in 0.44 μg/l cypermethrin+ascorbic acid supplemented diet group (62.23%), in 0.22 μg/l cypermethrin+control diet group (53.12%) and in 0.44 μg/l cypermethrin+control diet group (61.87%) after 10 days, respectively. These levels increased at the end of the recuperation period. The highest depletion in liver glycogen levels was found in 0.22 μg/l cypermethrin+control diet group (50.50%) after 10 days (p<0.05). At the end of recuperation period, there was no difference between the groups (except 0.22 μg/l cypermethrin+ascorbic acid supplemented diet group) and controls. The decrease of muscle glycogen, except 0.22 μg/l cypermethrin+ascorbic acid supplemented diet group, was recorded at the end of 10 and 20 days. In the recuperation period, an increase was observed at all groups. These results revealed that the histopathology, protein and glycogen can work as good indicators of stress of a toxicant on fish. Ascorbic acid serves fish as an antitoxic agent against pesticide toxicity.

Abstract
The aim of this study was to investigate the possible effects of the reproductive status and seasonal variations on the serum chemistry and vitamin status and their relationships with the thyroid hormones in Sakiz-Awassi crossbreed sheep. The sheep (n = 34) were divided into two groups. The first group (n = 22) was mated; the second group (n = 12) was not mated. Their serum samples were collected four times a year at the each season and under reproductive status. The periods are 1, early pregnancy (October); 2, late pregnancy (January); 3, lactation (April); and 4, dry season (July). The results of this study indicated that (1) total protein (TP), globulin, cholesterol, creatinine, uric acid and T4/T3 vary with reproductive status but not seasonal variations; (2) alanine aminotransferase, T4, fT4 concentrations in serum vary only with reproductive status; (3) the urea, creatine kinase, lactate dehydrogenase, alkaline phosphatase, aspartate aminotransferase, amylase, albumin, triglyceride, VLDL, Vit A-E, T3 and fT3 concentration could vary with both reproductive status and seasonal variations; (4) the glucose, gamma-glutamyl transpeptidase, folate concentrations were altered neither season of the year nor the reproductive status; (5) a single reference interval for folate, gamma-glutamyl transpeptidase (GGT), glucose, TP, globulin, cholesterol, creatinine, uric acid and T4/T3 can be used for both mated and non-mated sheep because of no differences were found due to the reproductive status. Taking the results together suggests that reproductive status and seasonal variations have to be taken into consideration for a correct interpretation of the serum chemistry values of sheep. Nutritional supplements are required for sheep during certain periods to avoid a decline of their performance, which would then represent consequent economic, loses.

Abstract
INTRODUCTION Gangrenous cholecystitis is a serious complication of acute cholecystitis. Male gender, older age, leukocytosis, cardio-vascular diseases and diabetes were reported as factors that increase the risk of gangrenous cholecystitis. The aim our study was to determine variables affecting morbidity and mortality as well as to define the independent risk factors in Gangrenous Cholecystitis. METHODS Fifty three patients who had been treated for Gangrenous Cholecystitis were reviewed. The variables are defined as follows: age, gender, systemic diseases, Mannheim Peritonitis index, aspartate aminotransferase, alanine aminotransferase, white blood cell count and type of surgery. In order to determine the independent risk factors that might affect morbidity and mortality in Gangrenous Cholecystitis, we made use of multivariate logistic regression analysis. RESULTS The independent risk factors affecting on morbidity were age (P = 0.037), existing systemic disease (P = 0.047) and > or = 29 Mannheim Peritonitis index (P = 0.008), and the independent risk factors affecting on mortality were age (P = 0.046), white blood cell count (P = 0.035). Pre-operative and post-operative third day aspartate amino-transferase and alanine aminotransferase average values were compared, there was a significant difference (P < 0.0001, P < 0.0001 respectively). CONCLUSIONS We found that older age, > or = 29 Mannheim Peritonitis index and existence of systemic diseases were independent risk factors affecting morbidity. Older age and lower of white blood cell count were independent risk factors affecting mortality. We believe that further comprehensive studies, involving prospective, multi-center and a large number of patients, are needed.

Abstract
Gliomatosis cerebri is a rare entity with non-specific clinical and conventional magnetic resonance imaging (MRI) findings; accurate diagnosis is a differential diagnostic challenge. MR spectroscopy has recently been introduced as a useful diagnostic tool for detection of this entity. We present a gliomatosis cerebri case in which we made the radiological diagnosis using the MR spectroscopy findings; the diagnosis was confirmed by subsequent biopsy and histopathologic evaluation. Multivoxel spectroscopy (CSI, PRESS, 1500/135) shows a marked increase in Cho/NAA (6.6), normal to mild increase in Cho/Cr (1.2), and marked decrease in NAA/Cr (0.2) compared with the normally appearing contralateral side (Cho/NAA: 0.8, Cho/Cr: 0.9, NAA/Cr: 1.2).
