RESUMO
OBJECTIVE: To compare and assess the effect of red beetroot extract and ozonated olive oil on wound healing in rats. STUDY DESIGN: Experimental study. Place and Duration of the Study: Department of Experimental Animal Research Laboratory, Faculty of Medicine, Aydin Adnan Menderes University, from June to July 2021. METHODOLOGY: Twenty-one, female Wistar albino rats were divided into 3 groups; red beetroot extract group (RBG, n=7), ozonated olive oil group (OOG, n=7), and physiological saline group (CG). Three round wound areas of similar shapes were produced on the back areas. Skin incisions with a diameter of 15 mm were made in rats with a scalpel under anaesthesia protocol. Beetroot extract was applied to RBG, ozonated olive oil to OOG, and saline to CG, once a day for 21 days. Tissue samples were taken from the wounds on the 3rd, 10th, and 21st day of the study, and a histopathological examination (Hematoxylin eosin staining) was performed for haemorrhage, congestion, necrosis, inflammation and fibrosis levels. Wound healing was also determined macroscopically by photography on same days. Serum oxidant (TOS, µmol H2O2 equivalents/L), antioxidant status (TAS, mmol trolox equivalents/L), serum total thiol (µmol/L), serum native thiol (µmol/L) and paraoxonase (PON, U/L) were determined from blood samples on the 21st day. RESULTS: Lower inflammation and higher blood antioxidant levels were determined in the RGB and OOG groups compared to the CG. A better wound healing on histology was observed in the OOG group compared to RGB. CONCLUSION: Red beetroot extract and ozonated olive oil enhanced wound healing in female rats. Ozonated olive oil had more effective wound-healing effect than beetroot extract. KEY WORDS: Wound healing, Ozonated olive oil, Red beetroot extract, Antioxidant effect.

OBJECTIVE: We tried to reveal how the normal appearing white matter (NAWM) was affected in patients with glioblastoma treated with chemo-radiotherapy (CRT) in the period following the treatment, by multiparametric MRI. MATERIALS AND METHODS: 43 multiparametric MRI examinations of 17 patients with glioblastoma treated with CRT were examined. A total of six different series or maps were analyzed in the examinations: Apparent Diffusion Coefficient (ADC) and Fractional Anisotropy (FA) maps, Gradient Echo (GRE) sequence, Dynamic susceptibility contrast (DSC) and Arterial spin labeling (ASL) perfusion sequences. Each sequence in each examination was examined in detail with 14 Region of Interest (ROI) measurements. The obtained values were proportioned to the contralateral NAWM values and the results were recorded as normalized values. Time dependent changes of normalized values were statistically analyzed. RESULTS: The most prominent changes in follow-up imaging occurred in the perilesional region. In perilesional NAWM, we found a decrease in normalized FA (nFA), rCBV (nrCBV), rCBF (nrCBF), ASL (nASL)values (p < 0.005) in the first 3 months after treatment, followed by a plateau and an increase approaching pretreatment values, although it did not reach. Similar but milder findings were present in other NAWM areas. In perilesional NAWM, nrCBV values were found to be positively high correlated with nrCBF and nASL, and negatively high correlated with nADC values (r: 0.963, 0.736, - 0.973, respectively). We also found high correlations between the mean values of nrCBV, nrCBF, nASL in other NAWM areas (r: 0.891, 0.864, respectively). DISCUSSION: We showed that both DSC and ASL perfusion values decreased correlatively in the first 3 months and showed a plateau after 1 year in patients with glioblastoma treated with CRT, unlike the literature. Although it was not as evident as perfusion MRI, it was observed that the ADC values also showed a plateau pattern following the increase in the first 3 months. Further studies are needed to explain late pathophysiological changes. Because of the high correlation, our results support ASL perfusion instead of contrast enhanced perfusion methods.

According to International Classification of Headache Disorders (ICHD-III Beta version) headache attributed to hypoxia and/or hypercapnia is classified under the 4 title: 10.1.1 High altitude headache, 10.1.2 Airplane travel associated headache, 10.1.3 Diving headache and 10.1.4 Sleep apnoea headache. Headache associated with airplane travel is encountered infrequently in our clinical practice and firstly reported in 2004 as a case in the literature. The pathophysiology of headache associated with airplane travel is not yet clear. We presented this case in the aspect of the patient having both airplane travel and high altitude headaches and seen giant Virchow-Robin spaces in cranial MRI and disappearence of pain with a preventive treatment.

Purpose: There is an annual incidence of 50,000 glioma cases in Europe. The optimal treatment strategy is highly personalised, depending on tumour type, grade, spatial localization, and the degree of tissue infiltration. In research settings, advanced magnetic resonance imaging (MRI) has shown great promise as a tool to inform personalised treatment decisions. However, the use of advanced MRI in clinical practice remains scarce due to the downstream effects of siloed glioma imaging research with limited representation of MRI specialists in established consortia; and the associated lack of available tools and expertise in clinical settings. These shortcomings delay the translation of scientific breakthroughs into novel treatment strategy. As a response we have developed the network "Glioma MR Imaging 2.0" (GliMR) which we present in this article. Methods: GliMR aims to build a pan-European and multidisciplinary network of experts and accelerate the use of advanced MRI in glioma beyond the current "state-of-the-art" in glioma imaging. The Action Glioma MR Imaging 2.0 (GliMR) was granted funding by the European Cooperation in Science and Technology (COST) in June 2019. Results: GliMR's first grant period ran from September 2019 to April 2020, during which several meetings were held and projects were initiated, such as reviewing the current knowledge on advanced MRI; developing a General Data Protection Regulation (GDPR) compliant consent form; and setting up the website. Conclusion: The Action overcomes the pre-existing limitations of glioma research and is funded until September 2023. New members will be accepted during its entire duration.
RESUMO
INTRODUCTION: Pituitary insufficiency (PI) needs further research to optimize treatment. Growth hormone deficiency (GHD) is a subtype of PI. The purpose of the present study is to investigate the possible relationship between GHD and the anatomical position of the pons as revealed by magnetic resonance imaging (MRI) in the pediatric age group. In the current study, we developed a novel and simple index using MRI that could provide an alternative to other indexes in the classical literature. PATIENTS AND METHODS: Brain MRI and clinical data of 48 children with suspected PI (22 females, 26 males; mean age 11.6 ± 2.2 years) were examined retrospectively. To estimate the location of the pons, the ratio of pons height over the axis between the dorsum sellae and the fourth ventricular hill in the sagittal plane (A) to the total height of the pons (B) was calculated (A/B). It was termed the pons ratio (PR). The PRs of children with or without a diagnosis of GHD were then compared statistically. RESULTS: Fifteen children were diagnosed with GHD and treated with growth hormone (GH), whereas the remaining 33 were reported normal. The mean PRs of the children diagnosed with GHD and given GH treatment (0.31 ± 0.07, range: 0.18-0.42) differed significantly from those without PI (0.26 ± 0.06, range: 0.17-0.44; P = 0.018). CONCLUSION: There appears to be an association between GHD and decreased PR in children receiving GH treatment. Spatial measurements of posterior fossa in radiological examinations may provide additional information that is helpful in the diagnosis of suspected cases of GHD.

INTRODUCTION: Atraumatic spontaneous rupture of the spleen is an uncommon but fatal condition that may coexist with other disease. Our case was presented with obvious CT findings of a spontaneous rupture of the spleen. PRESENTATION OF THE CASE: A 75-year-old woman admitted to the emergency service with abdominal pain. Although there was no evident splenomegaly in the abdominal CT examination, the patient was diagnosed with diffuse large B-cell lymphoma, and densities in harmony with the free air were detected in the spleen and the abdomen. DISCUSSION: It is clear that a healthy spleen does not rupture without marked trauma; hence, a doctor must carefully investigate the underlying pathology. Splenomegaly, the infiltration of the spleen and the capsule and consequently a splenic infarct and hemorrhage were set forth as the causes of the rupture of the spleen in lymphomas. However, our case had no splenomegaly or splenic involvement of lymphoma in the pathological examination. Even in the absence of splenomegaly, rupture may develop for such reasons as inflammation and embolism. Splenic infarcts are also in the developmental mechanism. CONCLUSION: Although atraumatic rupture of the spleen is not prevalent, it is a case which must be considered in an acute abdominal pain as it has highly fatal outcomes without CT exam.
RESUMO
The synovial and ganglion cysts originating from the facet joint have been named under the name of the Juxtafacet cyst by the several researchers. They put forward that the synovial cyst originated from the synovial joint. But, they failed to clarify the pathophysiology of the formation of the ganglion cyst. In this case report, we reported a 67-year-old male patient was referred to the emergency from another center with the complaint of a left leg pain and weakness in the left foot and patient was treated with microchirurgical technique. His patological examination was evaluated a ganglion cyst. We have discussed and explained the pathophysiology of the formation of a ganglion cyst derivered from a synovial cyst. And separately, we have presented the spinal cysts by grouping them under a new classification called a cystic formation of the soft tissue attachments of the mobile spine as well as dividing them into sub-groups.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiologic entity characterized by headache, seizures, visual changes, altered mental status, and focal neurologic signs. Typically, PRES involves the parietooccipital lobes; however, it can involve atypical localizations such as frontal lobe, basal ganglia, thalamus, brainstem, and gray matter. Sudden increases in blood pressure and associated renal failure are probably the most frequently encountered etiologies in the literature. Recurrence of PRES is not common. In this article, we present recurrent atypical PRES in a hypertensive child with end-stage renal disease on a peritoneal dialysis program as a rare case and we discuss recurrence. Infections and sudden increase in blood pressure were observed as the causes of recurrent PRES in our patient. The reversibility of PRES depends on immediate diagnosis and therapy; therefore, it should be kept in mind in the differential diagnosis of seizures or coma in chronic kidney disease patients.

Osteopetrosis is an uncommon congenital disorder characterized by defective osteoclastic resorption of bone that results in increased bone density. Clinical symptoms include anemia, hepatosplenomegaly, and cranial nerve and/or brainstem compression and hydrocephalus due to foraminal narrowing in the skull. The authors present an unusual case of a patient with autosomal recessive osteopetrosis associated with extensive calcification of the dura mater covering the brain as well as obstructive hydrocephalus. Ventriculoperitoneal shunt treatment was complicated by persistent overdrainage. It is suggested that chronic progressive triventricular hydrocephalus developed as a result of acquired aqueductal stenosis caused by extensive calcification of the tentorium cerebelli and calvarial hyperostosis. To the best of the authors' knowledge, this has not been described in the literature.

BACKGROUND: Pituitary apoplexy is a rare and life-threatening complication occurring in 0.6-10.5% of all cases of pituitary adenomas. Although the association between pituitary apoplexy and visual dysfunction has been recognized for a long time, the optimal management of this problem still remains controversial. The purpose of this overview was to present the surgical experience by analyzing the literature on the management of pituitary apoplexy for better treatment of these cases. MATERIALS AND METHOD: To establish a new guideline for the surgical treatment of this entity, publications reported during the last century and databases containing medical literature were analyzed. In addition, an illustrative case with pituitary apoplexy presenting with complaints of sudden onset severe headache associated with nausea, vomiting, and a sudden loss of vision was described. In fact, the experience in our complicated patient prompted us to review the available literature on the management of pituitary apoplexy to date. CONCLUSIONS: Based on an overview of 186 cases of apoplectic pituitary adenoma presenting with monocular or binocular blindness, we highlight the importance of correct diagnosis and an early, but not necessarily emergency, surgery within the first week of admission to optimize visual outcome of such patients. The illustrative case further exemplifies the value of close interaction between members of the management team for optimal outcome.

RATIONALE AND OBJECTIVES: Distinguishing recurrent glial tumor from radiation necrosis can be challenging. The purpose of this pilot study was to preliminarily compare unenhanced arterial spin-labeled (ASL) imaging, dynamic susceptibility contrast-enhanced cerebral blood volume (DSCE-CBV) magnetic resonance imaging, and positron emission tomographic (PET) imaging in distinguishing predominant glioma recurrence or progression from predominant radiation necrosis in postoperative patients treated with proton-beam therapy. METHODS: Patients with grade II to IV glioma previously treated with surgery and proton-beam therapy were enrolled on the basis of new enhancing nodules or masses with primary differential diagnoses of predominant tumor recurrence or progression versus radiation necrosis. ASL, DSCE-CBV, and PET examinations were assessed by visual qualitative and quantitative analysis for the detection of predominant tumor recurrence. Imaging results were correlated with a clinical-pathologic reference standard. RESULTS: Thirty patients were studied, resulting in 33 ASL, 32 DSCE-CBV, and 26 PET examinations. On the basis of visual inspection, the sensitivities of PET, ASL, and DSCE-CBV examinations for detecting high-grade tumor foci were 81%, 88%, and 86%, respectively. The highest sensitivity values for quantitative ASL imaging were obtained using a normalized cutoff ratio of 1.3, resulting in sensitivity of 94% for ASL imaging and 71% for DSCE-CBV imaging. When predominant high-grade tumors with superimposed regions of predominant mixed radiation necrosis were excluded, DSCE-CBV sensitivity improved to 90%, but ASL sensitivity remained unchanged. CONCLUSIONS: Compared with DSCE-CBV imaging, ASL imaging may more accurately distinguish predominant recurrent high-grade glioma from radiation necrosis, especially in regions with mixed radiation necrosis, for which DSCE-CBV imaging may underestimate true blood volume because of leakage artifacts.

The aim of this study was to determine the course of the median nerve and its adjacent structures in the carpal canals of 8 healthy dogs by using high-frequency transducers. Before performing ultrasonography, the transverse and posteroanterior diameters as well as the perimeter of the carpus were measured at just proximal to the side of the carpal pad. The anatomical structures were then determined at two levels of the carpal canal, which were named the proximal and distal levels, on the transverse sonograms. The cross-sectional areas, perimeters and the transverse and posteroanterior diameters of the median nerve were measured at these levels. Although all the measurements were larger at the proximal level, significant differences between the proximal and distal levels were determined for the cross-sectional area, the perimeter and the transverse diameter of the median nerve. On the transverse sonogram, the deep digital flexor tendon was seen in almost the center of the carpal canal like a comma shape and also it had a small concavity on the caudal side. The superficial digital flexor tendon was seen as an ovoid shape on the transverse sonograms and it was located nearly at the posterior side of the carpal canal. Both tendons were seen as intermediate-grade echogenic structures. The median artery was located inside of the concavity of the deep digital flexor tendon. Also, the median nerve was seen at the posteromedial side of the median artery. As a result of this study, the cross-sectional areas of the median nerve ranged between 1.01-2.68 mm(2) at the proximal level and between 0.93-1.91 mm(2) at the distal level.

OBJECTIVE: We compared the accuracy and tolerability of intravenous contrast enhanced spiral computed tomography colonography (CTC) and optical colonoscopy (OC) for the detection of colorectal neoplasia in symptomatic patients for colorectal neoplasia. METHODS: A prospective study was performed in 48 patients with symptomatic patients with increased risk for colorectal cancer. Spiral CTC was performed in supine and prone positions after colonic cleansing. The axial, 2D MPR and virtual endoluminal views were analyzed. Results of spiral CTC were compared with OC which was done within 15 days. The psychometric tolerance test was asked to be performed for both CTC and colonoscopy after the procedure. RESULTS: Ten lesions in 9 of 48 patients were found in CTC and confirmed with OC. Two masses and eight polyps, consisted of 1 tubulovillous, 1 tubular, 2 villous adenoma, 4 adenomatous polyp, 4 adenocarcinoma, were identified. Lesion prevalence was 21%. Sensitivity, specificity, accuracy, positive and negative predictive values were found 100%, 87%, 89%, 67% and 100%, respectively. Psychometric tolerance test showed that CTC significantly more comfortable comparing with OC (p=0.00). CTC was the preferred method in 37% while OC was preferred in 6% of patients. In both techniques, the most unpleasant part was bowel cleansing. CONCLUSION: Contrast enhanced CTC is a highly accurate method in detecting colorectal lesions. Since the technique was found to be more comfortable and less time consuming compare to OE, it may be preferable in management of symptomatic patients with increased risk for colorectal cancer.

PURPOSE: The evaluation of orbital blood flow parameters in patients with unilateral pseudoexfoliation syndrome (XFS) and in age-sex-matched control subjects using color Doppler imaging. METHODS: This prospective, comparative case series included 33 unilateral XFS patients and 33 age-sex-matched control subjects. Color Doppler imaging was used to evaluate the XFS-affected (Group 1) and -unaffected (Group 2) eyes that were matched with the corresponding side (Groups 3 and 4) of control subjects. All subjects were given a complete ophthalmological examination. A masked radiologist obtained the peak systolic velocity (PSV) and end diastolic velocity (EDV) of ophthalmic (OA), central retinal (CRA), nasal posterior ciliary (NPCA) and temporal posterior ciliary arteries (TPCA) as well as mean velocity of central retinal vein (CRV). Resistivity indices (RI) were calculated. RESULTS: Analysis of peak systolic and end diastolic velocity (PSV, EDV) and RI between Groups 1-2 and 3-4 did not show any significant difference. Comparing Groups 1-3 (corresponding eyes of pseudoexfoliation-affected and control subjects) and Groups 2-4 (corresponding eyes of pseudoexfoliation-unaffected and control subjects) revealed significantly low values for OA, PSV and EDV in both eyes of the XFS patients. The OA RI value in Group 1 was found to be significantly higher than that in Group 3 with the cut-off value of 0.72. CONCLUSION: These findings suggest that ophthalmic artery hemodynamic parameters change in both eyes of unilateral XFS patients, illustrating out the systemic nature of the disease. We conclude that XFS decreases OA blood flow velocities and increases vascular resistance through progressive build-up.

The goal of this cross-sectional observational study was to determine the incidence of pineal gland calcification (PGC), to investigate the interaction of PGC and aging, and to compare the incidence of PGC among the populations living in Turkey. In a prospective study the rate of PGC on CT scans of 1376 individuals in six referral centers from different regions of Turkey was investigated, with emphasis on effects of climatological parameters and aging on PGC. It was found that the incidence of PGC increased rapidly after first decade and the increase remains gradual thereafter, higher in males than in females for all age groups. There was a significant difference for incidence and degree of PGC between different clinics and between both sexes (p<0.001). In addition, there was a significant difference for the degree of PGC between the clinics in low altitude group and those in high altitude group (p<0.001 for each). Logistic regression analysis revealed that age, sex, altitude and intensity of sunlight exposure significantly affected the risk of PGC (odds ratios (OR) 1.335, 95% confidence intervals (CI) 1.261-1.414, p<0.001; OR 1.900, 95% CI 1.486-2.428, p<0.001; OR 0.715, 95% CI 0.517-0.990, p<0.05; OR 0.997, 95% CI 0.994-0.999, p<0.01, respectively). Furthermore, by multiple linear regression analysis, high altitude and increased intensity of sunlight exposure were found to affect the degree of PGC (beta=0.003, p<0.001). It is concluded that there is a close relationship between PGC and the aforementioned parameters, supporting a link between the development of PGC and these. This study provides some reference data for new clinical studies on the putative role of pineal gland in future.
RESUMO
BACKGROUND: Involvement of the brain by Aspergillus fumigatus, named as invasive aspergillosis, is extremely rare. Definitive diagnosis needs isolation of the fungus from the tissue specimens and its culture. The disease is very resistant to treatment and quickly becomes fatal despite antifungal chemotherapy with AmB preparations, the drugs of choice for the infection. CASE DESCRIPTION: We hereby present a unique case of fungal granuloma of the brain due to A fumigatus, which was cured successfully by intensive antifungal treatment, along with a brief literature review. CONCLUSIONS: Although it is rare, we draw the attention to the fact that early diagnostic procedures with rapid confirmation of Aspergillus infection and an early initiation of therapy are pivotal for a benign clinical course in such cases. A complete regression of the disease could be achieved with medical therapy alone with conventional AmB or liposomal AmB combined with oral itraconazole even if a total surgical excision of the lesions could not be performed in complicated cases, as in our patient.

PURPOSE: To determine the quality of radiographs, which have been referred from 40 different institutions for consultation, to discuss the causes of wasted resources, and to present possible solutions. MATERIALS AND METHODS: Five experienced radiology instructors determined the types of radiological examinations referred for consultation (conventional radiography, mammography, computed tomography and magnetic resonance imaging), the institutions at which they were performed (university or state hospital, private health center), and assessed the coverage area, field of vision (FOV), and dosage of x-ray. They also investigated problems in film processing, defects in sequence-printing windows, checked window levels, and checked the amount and timing of contrast material used. According to these criteria, the reviewers subjectively classified each radiograph as: 1. Poor, examination should be completely repeated, 2. Fair, examination should be partially repeated, 3. Good, accepted as adequate, no need for an additional examination, 4. Excellent, examination was as it should be. RESULTS: We reviewed 120 radiological examinations from 40 different institutions in 4 reference centers. Frequency of problems determined for each category was as follows: coverage area 32.5% (39/120), FOV 16% (14/86), X-ray dosage 16% (15/94), film processing 31% (37/120), sequence or window 65% (53/81), window level 44% (36/81); contrast material 51% (25/49), timing of contrast material 61% (30/49). Only 22% of the examinations were classified as excellent, whereas 47% required complete or partial repetition. CONCLUSION: Approximately half of the radiological examinations in our sampling required partial or complete repetition. Health, ethical, and economic aspects of the problem necessitates the prompt application of measures to establish radiological quality control and standardization procedures.

Angioleiomyoma is an uncommon type of leiomyoma of the uterus that originates from smooth muscle cells and contains thick-walled vessels. A 45-year-old woman with the complaint of lower abdominal pain was admitted to the hospital. In the operation a ruptured, bleeding uterine tumor was seen. She underwent total hysterectomy and bilateral salpingo-oophorectomy. On pathologic examination of the specimen, the tumor was diagnosed as angioleiomyoma. Here, an unusual clinical presentation of uterine angioleiomyoma was reported.

The aim of our study was to assess the blood concentrations of some trace elements and melatonin (MLT) in patients with intervertebral disc herniation (IDH) and to investigate the interaction of histological and biochemical degeneration findings with aging. The present study was carried out on 13 subjects (8 women and 5 men) diagnosed with IDH. They were divided into three groups according to their ages. Nighttime serum MLT, zinc (Zn), and magnesium (Mg) levels were determined in all patients. In addition, computed tomography (CT) scan of the brain and magnetic resonance imaging examination of the lumbar spine were obtained in this study. The Zn level and Zn/Mg ratio showed a decline in patients with IDH with aging, whereas the serum Mg level and tissue hydroxyproline content increased. A positive correlation between serum Zn and MLT concentrations was found (r=0.104, p=0.734). In addition, there was a positive correlation between serum Zn level and Zn/Mg ratio (r=0.835 and p<0.01), and a negative correlation between serum Mg level and Zn/Mg ratio (r=-0.571, p<0.05). On CT study, both volume percentage of calcified pineal gland and density of calcification were found to increase progressively with advancing age. The results of semiquantitative evaluation of disc tissues of patients with IDH for histological degeneration findings showed that 66.7% of discs treated had slight degeneration in younger age group, but 75.0% and 100% of discs had moderate or marked degeneration in older age groups. Our data indicated that there is a close relationship between MLT and Zn or Mg levels in the serum samples of patients with IDH, and the levels of these elements might be affected by the presence of degeneration process and serum MLT level, or vice versa.
