RESUMO
The objective of this paper is to evaluate the association between physical disability in multiple sclerosis (MS) patients, the thickness of the retinal nerve fibre layer (RNFL) and corpus callosum volumes, as expressed by the corpus callosum index (CCI). This study was based on a cohort of 212 MS patients and 52 healthy control subjects, who were age and gender matched. The MS patients included 144 women and 177 relapsing-remitting MS (RRMS) patients. Peripapillary and volumetric optical coherence tomography (OCT) scans of the macula were performed using spectral-domain OCT technology. All magnetic resonance imaging (MRI) scans were performed using 1.5-T systems. CCI and RNFL were lower in MS than healthy control subjects (0.341 versus 0.386, p < 0.01 and 92.1 versus 105.0, p < 0.01). In addition, CCI correlated with RNFL (r = 0.464, p < 0.01). This was also true for the subgroup of patients with no history of optic neuritis (ON). There is a correlation between the thickness of the RNFL and CCI values in MS patients with no history of ON, which suggests that OCT might be a suitable marker for neurodegeneration in MS clinical trials.

A solitary fibrous tumour (SFT) is a rare mesenchymal tumour that frequently originates in the mesothelium-covered surfaces, such as the pleura and peritoneum. It may develop in various body parts, including the head and neck. These tumours may arise in several different patterns, which results in difficulties in diagnosing them. This case is a solitary tumour developing from the palatine tonsil in a 17-year-old male patient; it is the second case in the literature. The tumour has the histopathological characteristics of a patternless pattern, a slight pleomorphism, and a composition of hypercellular and hypocellular sites. Immunohistochemically, the tumour cells showed a strong positive staining with CD34, Bcl-2, and vimentin. No recurrence developed in the patient's approximately 18-month-long follow-up period.

BACKGROUND: Diagnostic performance of Diffusion-Weighted magnetic resonance Imaging (DWI) and Multi-Detector Computed Tomography (MDCT) for TNM (Tumor, Lymph node, Metastasis) staging of gastric cancer was compared. PATIENTS AND METHODS: We used axial T2-weighted images and DWI (b-0,400 and b-800 s/mm2) protocol on 51 pre-operative patients who had been diagnosed with gastric cancer. We also conducted MDCT examinations on them. We looked for a signal increase in the series of DWI images. The depth of tumor invasion in the stomach wall (tumor (T) staging), the involvement of lymph nodes (nodal (N) staging), and the presence or absence of metastases (metastatic staging) in DWI and CT images according to the TNM staging system were evaluated. In each diagnosis of the tumors, sensitivity, specificity, positive and negative accuracy rates of DWI and MDCT examinations were found through a comparison with the results of the surgical pathology, which is the gold standard method. In addition to the compatibilities of each examination with surgical pathology, kappa statistics were used. RESULTS: Sensitivity and specificity of DWI and MDCT in lymph node staging were as follows: N1: DWI: 75.0%, 84.6%; MDCT: 66.7%, 82%;N2: DWI: 79.3%, 77.3%; MDCT: 69.0%, 68.2%; N3: DWI: 60.0%, 97.6%; MDCT: 50.0%, 90.2%. The diagnostic tool DWI seemed more compatible with the gold standard method (surgical pathology), especially in the staging of lymph node, when compared to MDCT. On the other hand, in T staging, the results of DWI and MDCT were better than the gold standard when the T stage increased. However, DWI did not demonstrate superiority to MDCT. The sensitivity and specificity of both imaging techniques for detecting distant metastasis were 100%. CONCLUSIONS: The diagnostic accuracy of DWI for TNM staging in gastric cancer before surgery is at a comparable level with MDCT and adding DWI to routine protocol of evaluating lymph nodes metastasis might increase diagnostic accuracy.
RESUMO
BACKGROUND: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder characterized by intermittent hypoxia. Non-alcoholic fatty liver disease is the most common cause of chronic liver disease worldwide. We aimed to evaluate the relationship between OSA and fatty liver. MATERIAL/METHODS: We enrolled 176 subjects to this study who underwent polysomnography (PSG) for suspected OSA. The control group included 42 simple snoring subjects. PSG, biochemical tests, and ultrasonographic examination were performed all subjects. RESULTS: The simple snoring and mild, moderate, and severe OSA groups included 18/42 (42.86%), 33/52 (63.5%), 27/34 (79.4%), and 28/48 (79.2%) subjects with hepatosteatosis, respectively. There were significant differences in hepatosteatosis and hepatosteatosis grade between the simple snoring and the moderate and severe OSA groups. Logistic regression analysis showed that BMI and average desaturation were independently and significantly related to hepatic steatosis. CONCLUSIONS: Our study shows that BMI and the average desaturation contribute to non-alcoholic fatty liver in subjects with OSA. In this regard, sleep apnea may trigger metabolic mitochondrial energy associated processes thereby altering lipid metabolism and obesity as well.

BACKGROUND Because loss of cervical lordosis leads to disrupted biomechanics, the natural lordotic curvature is considered to be an ideal posture for the cervical spine. The vertebral arteries proceed in the transverse foramen of each cervical vertebra. Considering that the vertebral arteries travel in close anatomical relationship to the cervical spine, we speculated that the loss of cervical lordosis may affect vertebral artery hemodynamics. The aim of this study was to compare the vertebral artery values between subjects with and without loss of cervical lordosis. MATERIAL AND METHODS Thirty patients with loss of cervical lordosis and 30 controls matched for age, sex, and body mass index were included in the study. Sixty vertebral arteries in patients with loss of cervical lordosis and 60 in controls without loss of cervical lordosis were evaluated by Doppler ultrasonography. Vertebral artery hemodynamics, including lumen diameter, flow volume, peak systolic velocity, end-diastolic velocity, and resistive index, were measured, and determined values were statistically compared between the patient and the control groups. RESULTS The means of diameter (p=0.003), flow volume (p=0.002), and peak systolic velocity (p=0.014) in patients were significantly lower as compared to controls. However, there was no significant difference between the 2 groups in terms of the end-diastolic velocity (p=0.276) and resistive index (p=0.536) parameters. CONCLUSIONS The present study revealed a significant association between loss of cervical lordosis and decreased vertebral artery hemodynamics, including diameter, flow volume, and peak systolic velocity. Further studies are required to confirm these findings and to investigate their possible clinical implications.

OBJECTIVES: The aim of this study was to detect the level of stiffness of parathyroid adenomas and to distinguish them from benign and malignant thyroid nodules using ultrasound elastography with acoustic radiation force impulse imaging. METHODS: Twenty-one patients with parathyroid adenomas and 71 patients with thyroid nodules were evaluated by acoustic radiation force impulse imaging in this study. Acoustic radiation force impulse elastograms were obtained after evaluation of the thyroid nodules, which were predicted to undergo fine-needle aspiration biopsy, and patients with a diagnosis of hyperparathyroidism, which was identified by sonography at the same time. RESULTS: An analysis of mean shear wave velocity (SWV) values for parathyroid adenomas and thyroid nodules showed that parathyroid adenomas had significantly higher stiffness levels compared to benign thyroid nodules (mean SWV ± SD, 3.09 ± 0.75 versus 2.20 ± 0.39 m/s; P < .001) and lower stiffness levels compared to malignant thyroid nodules (mean SWV, 3.09 ± 0.75 versus 3.59 ± 0.43 m/s; P < .001). CONCLUSIONS: Acoustic radiation force impulse imaging has high sensitivity and specificity for differentiating parathyroid adenomas from benign and malignant thyroid nodules. As an adjunctive tool, it can help distinguish parathyroid adenomas from thyroid nodules, including posteriorly located nodules.

BACKGRUND: Hemolytic uremic syndrome is a disease characterized by hemolytic anemia, thrombocytopenia and acute renal failure with multiple organ involvement. Central nervous system involvement is detected in 20-50% of the patients and this leads to increased morbidity and mortality. CASE REPORT: We report the neuroimaging findings in a four-month-old male with hemolytic uremic syndrome. The cerebral cortex and white matter showed mild signal intensity on T2-weighted images. The diffusion weighted imaging demonstrated restricted diffusion in the cerebral cortex and white matter with corresponding low signal intensity on the apparent diffusion coefficient maps representing cytotoxic edema. These findings ended in multicystic leukoencephalomalacia. CONCLUSIONS: In hemolytic uremic syndrome with brain involvement symptoms develop due to the different level of actions of factors and thus MRI protocol towards cerebral parenchyma should include DWI, especially in pediatric patients.
RESUMO
PURPOSE: To evaluate anterior hepatic grooves (AHGs) associated with hepato-diaphragmatic mesocolic indentations (Chilaiditi sign) and to delineate the incidence and potential clinical significance of this association. METHODS: Between November 2011 and June 2014, abdominal computed tomography examinations of 2,314 patients with varied indications were retrospectively reviewed. Patients were surveyed consecutively for the Chilaiditi sign and syndrome, and cases with grooves at the antero-inferior hepatic surface enclosing the adjacent mesocolic indents were determined. The incidence of AHGs and their predominance by gender and age were determined. The potential clinical significance of AHGs associated with Chilaiditi syndrome and their possible effect on liver volume were assessed. RESULTS: The incidences of AHGs were similar between genders (p = .461 and p = .646) and age (p = .113 and .621, respectively) among total cohort and patients with Chilaiditi sign, respectively. There was no significant correlation between AHGs and Chilaiditi syndrome (p = .506); no efficacies of AHGs to liver volume were assessed (p = .413). CONCLUSIONS: The AHGs are rare adaptive changes in shape of the liver without a significant effect on liver volume. This overlooked phenomenon is likely derived from the Chilaiditi sign, but has no significant correlation with Chilaiditi syndrome. Future studies with extended series are encouraged to reveal the possible significance of this phenomenon based on concerned surgical interventions.

BACKGROUND: Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly. We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic. This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic. CASE REPORT: A man at the age of 34 years with blunt trauma dating back to 1.5 month was admitted to the emergency department of a hospital with hematemesis and epigastric tenderness. He also had a duodenal ulcer, blood in the gastric lumen and a large pseudoaneurysm that developed from the left hepatic artery. Soon after the diagnosis, the patient worsened and underwent distal gastrectomy and cholecystectomy that included removing the bleeding aneurysm. CONCLUSIONS: Ruptured hepatic artery pseudoaneurysm stands as a deadly condition which has to be diagnosed and managed as soon as possible. Physicians need to take aneurysms of abdominal arteries into consideration after routine diagnostic practises as long as the cause of gastrointestinal haemorrhage is unidentified.
RESUMO
BACKGROUND: Arachnoid cysts are congenital, benign and intra-arachnoidal lesions. A great majority of arachnoid cysts are congenital. However, to a lesser extent, they are known to develop after head trauma and brain inflammatory diseases. Arachnoid cysts are mostly asymptomatic and they can develop anywhere in the brain along the arachnoid membrane. CASE REPORT: Arachnoid cysts form 1% of the non-traumatic lesions which occupy a place and it is thought to be a congenital lesion developed as a result of meningeal development abnormalities or a lesion acquired after trauma and infection. There is a male dominance at a rate of 3/1 in arachnoid cysts which locate mostly in the middle fossa. Our patient was a 2-years-old boy. CONCLUSIONS: As a conclusion, spontaneous subdural hygroma is a rare complication of the arachnoid cysts. Surgical intervention could be required in acute cases.

Actinomycosis is a rare, chronic, suppurative and granulomatous disease caused by Actinomyces israelii, which is a filamentous, anaerobic, gram-positive, saprophytic organism in the oral cavity. Diagnosis of actinomycosis depends on positive culture or identification of Actinomyces colonies and sulfur granules in histological specimens. In our case, a mass had been growing in the mandible for eight months. The mass appeared to be malignant, both clinically and radiologically. A histopathological examination of the mandible revealed actinomycosis. It should be noted that actinomycosis can mimic a malignancy, and for differential diagnosis, bone biopsy or fine-needle aspiration should be performed pre-operatively.

PURPOSE: To investigate the feasibility of acoustic radiation force impulse imaging in differentiation of endometriomas and hemorrhagic ovarian cysts. MATERIALS AND METHODS: We evaluated 84 ovarian cysts with high internal echogenicity diagnosed in 70 consecutive women. We excluded simple cysts and hemorrhagic cysts containing septations or mural nodules with detectable flow on Doppler ultrasonography. We obtained the elastographic shear wave velocity (SWV) value of the cysts that could be endometriomas or hemorrhagic ovarian cysts. RESULTS: Among the 78 ovarian cysts in 70 women without any septation or mural nodule, there were 42 endometriomas and 36 hemorrhagic ovarian cysts. Analysis of median SWV values of the ovarian cysts showed that the endometriomas had considerably higher levels of stiffness compared to the hemorrhagic ovarian cysts [median SWV 4.20 ± 0.42 vs 2.54 ± 1.04 m/s, p < 0.001]. A SWV cutoff value greater than 3.81 m/s yielded sensitivity and specificity values of 82.1 and 79.2 % respectively, for differentiation of endometriomas from hemorrhagic ovarian cysts. CONCLUSION: Sonoelastography is a novel imaging technique that enables us to evaluate the stiffness of adnexal lesions. The accurate discrimination of endometriomas and hemorrhagic ovarian cysts is important for avoiding unnecessary surgical procedures. ARFI imaging has a high sensitivity and specificity for distinguishing endometrioma from hemorrhagic ovarian cysts.

We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a nonfunctioning left adrenal mass in a 25-year-old woman with continuous pain in the left flank. Preoperative biochemical testing confirmed that the mass was nonfunctional. Bronchogenic cysts are mostly benign congenital abnormalities that originate from the remnants of the primitive foregut and typically occur in the lung. Subdiaphragmatic and especially, retroperitoneal locations are rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Diagnosis must be definitively confirmed by histology.

A 23-year-old man with Dyke-Davidoff-Masson syndrome (DDMS) was admitted to the hospital with increasing frequency of epileptic seizures. Physical examination revealed mental retardation, left facial asymmetry, and left-sided spastic hemiparesis. Dysdiadochokinesia on the left upper limb was detected, and there was no dysmetria. MRI confirmed the well-known radiological features of DDMS. PET/CT demonstrated cerebral and contralateral cerebellar hypometabolism. We present DDMS with crossed cerebellar diaschisis, which was demonstrated by PET/CT.

Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

AIMS: To evaluate the feasibility of quantitative analysis of muscle stiffness by Acoustic Radiation Forced Impulse (ARFI) elastography over a course of graduate isometric voluntary contractions. MATERIAL AND METHODS: The stiffness of the bilateral biceps muscle of 13 healthy volunteers was measured in real time by ARFI elastography, while the forearm was in neutral-extended position, 90 degree self-flexed positions and 90 degree self-flexed position, with altered weights ranging from 1 to 8 kg placed on flattened palmar surfaces consecutively. The determined increases in biceps muscle stiffness were measured for both arms and correlated with the loadings weights adopted at progressive trial stages. RESULTS: The mean shear wave velocity (SWV) values of biceps muscles in a neutral position, in 90 degree flex position and 90 degree flex position with 1 to 8 kg weights on palmar surfaces were 2.162+/-0.302 m/sec, 3.382+/-0.581 m/sec, and 3.897+/-0.585 to 5.562+/-0.587 m/sec, respectively. Significant correlations between the muscle SWV values and related palmar weights and between the SWV values of right and left sides at different trial stages were identified (r=0.951 and r=0.954, respectively). A mutual propagation path of deep regions to entire areas was described to account for the distribution of increase in stiffness with increases in palmar weights. The confidence of method regarding inter-observer difference was confirmed by the correlation analyses of the results (r=0.998). CONCLUSIONS: ARFI elastography is a feasible imaging modality for quantifying the stiffness of isometrically voluntarily contracting muscles.

PURPOSE: The purpose of our study was to assess the efficiency of diffusion-weighted magnetic resonance imaging (DW-MRI) and the quantification of apparent diffusion coefficient (ADC) values in differentiating colorectal carcinoma from colonic inflammatory bowel disease (IBD) in cases with isolated colonic wall lesions and uncertain clinical and radiologic diagnostic criteria. METHODS: The study comprised 58 patients with segmental or focal isolated colonic wall thickening. All lacked satisfactory clinical-radiological findings for etiology determination. The mean ADC values of the thickened colonic walls were retrospectively compared with final histopathologic diagnoses. Receiver operating characteristic (ROC) curve analysis was used to determine the ADC cutoff value for differentiation. RESULTS: Mean ADC value in the colorectal carcinoma group was significantly lower than that in the IBD group: n = 27, 1.02 ± 0.26 × 10(-3) mm(2)/s; and n = 31, 1.53 ± 0.19 × 10(-3) mm(2)/s, respectively (P < 0.001). Cutoff ADC value for differentiating colorectal carcinoma from IBD was calculated as 1.39 × 10(-3) mm(2)/s, with 83.9 % sensitivity and 85.2 % specificity. CONCLUSION: ADC measurement of the involved colonic wall segments with DW-MRI has the potential to differentiate isolated colonic IBD from colorectal carcinoma in cases in which clinical-radiologic findings are insufficient for a definitive diagnosis.

Blank cartridge guns are devices that discharge sound and gas, but no bullet or shot. These devices are very similar to real guns in the form of their external design and the sound generated during their firing. Although it is widely held in society that these devices are harmless, reports from Turkey and the world have shown that these guns are not entirely innocent. Herein, we present a 26-year-old male with a head injury due to gunshot from a blank cartridge. The purpose of this presentation is to emphasize that these devices are not harmless, contrary to common public opinion.
