- Abstract
The increasing use of mobile phones may have a number of physiological and psychological effects on human health. Many animal and human studies have reported various effects on the central nervous system and cognitive performance from of exposure to electromagnetic fields (EMF) emitted by mobile phones. The aim of the present study was to evaluate the effects of mobile phones on the morphology of the human brain and on cognitive performance using stereological and spectroscopic methods and neurocognitive tests. Sixty healthy female medical school students aged 18-25 years were divided into a low exposure group (30 subjects, <30 min daily use by the head) and high exposure group (30 subjects, >90 min daily use by the head). Magnetic resonance images (MRI) of the brain analysed on OsiriX 3.2.1 workstation. Neuropsychological tests were performed for each subject. In addition, three dominant specific metabolites were analysed, choline at 3.21 ppm, creatine at 3.04 ppm and N -acetyl aspartate at 2.02 ppm. Analysis of the spectroscopic results revealed no significant difference in specific metabolites between the groups (p > 0.05). There was also no significant difference in terms of hippocampal volume between the groups (p > 0.05). In contrast, the results of the stroop and digit span (backward) neurocognitive tests of high exposure group for evaluating attention were significantly poorer from low exposure group (p < 0.05). Based on these results, we conclude that a lack of attention and concentration may occur in subjects who talk on mobile phones for longer times, compared to those who use phones relatively less.

- Abstract
Psoas abscess associated with septic arthritis of the hip is unusual in infants. A 12-month-old infant presented with the complaints of fever, left hip pain and limp. Magnetic resonance imaging revealed left psoas abscess accompanied by septic arthritis of the hip. In this report, we present a case of psoas abscess with hip septic arthritis in an infant, and we describe the clinical and radiological findings and treatment of this case.

- Abstract
Objective: The aim of this study was to evaluate the characteristics of bone and soft tissue tumors operated on at the Department of Orthopedics and Traumatology at Ondokuz Mayıs University Faculty of Medicine Hospital between January 1987 and January 2012., Methods: This descriptive study retrospectively evaluated 1,925 patients hospitalized with a preliminary diagnosis of tumor. Patients were analyzed for age, gender, tumor incidence and localization. Three hundred and forty-nine patients found to have non-tumor causes. The 94 patients discharged at their own request or deceased during follow-up were not included in the tumor group., Results: Of the 1,482 (76.9%) patients diagnosed with tumor, 687 (46.4%) were bone tumors, 586 (39.5%) soft tissue tumors and 209 (14.1%) metastatic tumors. The most common benign bone tumor was osteochondroma (118; 25%), followed by enchondroma (68; 14.4%) and giant cell tumor (59; 12.5%), and the most common malignant bone tumor was osteosarcoma (58; 27%), followed by chondrosarcoma (36; 16.7%) and Ewing's sarcoma (33; 15.3%). The most common benign soft tissue tumor was cystic hygroma (96; 22%), followed by lipoma (75; 17.2%) and hemangioma (52; 11.9%), and the most common malignant soft tissue tumors were pleomorphic cell tumor (29; 19.3%) and liposarcoma (29; 19.3%), followed by pleomorphic undifferentiated sarcoma (21; 14%). Seventy (33.5%) of the metastatic tumors were of pulmonary origin, 36 (17.2%) were of breast origin and the primary site of the tumor was not clearly determined in 58 (27.8%) patients., Conclusion: The distribution of bone and soft tissue tumors appear to have certain characteristics but can show regional differences. We believe that the establishment of a larger series through the collection of these types of studies from centers in which bone and soft tissue tumor surgery is performed will provide important information on the epidemiological features of bone and soft tissue tumors.

- Abstract
Objectives: We retrospectively evaluated patients with intraosseous lipoma., Methods: The study included eight patients (5 males, 3 females; mean age 39 years; range 23 to 60 years) who were treated between 1997 and 2005 for intraosseous lipoma. Localizations of the lipomas were the calcaneus in six patients, proximal humerus in one patient, and proximal femur in one patient. The presenting complaints were heel pain in patients with calcaneal involvement, and shoulder pain associated with proximal humeral involvement. In one patient, detection of intraosseous lipoma in the left proximal femur was incidental during examination for right hip pain. According to the Milgram classification, five of the intraosseous lipomas were stage 1, while two calcaneal lesions and one femoral lesion were stage 2. Treatment consisted of excisional biopsy, curettage, and allografting under regional or general anesthesia. The diagnosis was confirmed histopathologically in all cases. The mean follow-up period was 28 months (range 9 to 110 months)., Results: Complaints of heel pain and shoulder pain resolved within four and five months, respectively. No infection or skin necrosis occurred at the wound site. No neurovascular complications developed during or after surgery. Radiological consolidation of the implanted bone allografts were complete by a mean of three months (range 2 to 4 months). No pathological fractures or recurrences were encountered., Conclusion: Treatment of intraosseous lipomas with curettage and grafting is effective in relieving pain and preventing possible pathological fractures.

- Abstract
Background: Autosomal dominant polycystic kidney disease (ADPKD) is a systemic hereditary disorder characterized by bilateral diffuse renal cysts. Extrarenal involvement is a well known manifestation of ADPKD. Data relating to the association between seminal vesicle cysts and ADPKD are limited. The aims of this study are to evaluate the frequency of seminal vesicle cysts in ADPKD and to assess the relationship between seminal vesicle cysts, with cysts in the liver and prostate, and creatininaemia., Methods: Forty five male patients (mean age 40 years, range 13-67) were included in the study. Each subject underwent a formal interview, physical examination; and abdominal and transrectal ultrasonography. Three patients were infertile, but one of the patients also had varicocele., Results: Seminal vesicle cysts were present in 27 (60%) patients. Liver and prostate cysts were present in 19 (42%) and five (11%) patients, respectively. There was a positive correlation between seminal vesicle cysts, cysts in the liver, and serum creatinine concentrations., Conclusion: Our conclusions are: (i) seminal vesicle cysts are not uncommon in ADPKD; (ii) ADPKD should be looked for in patients with seminal vesicle cysts, and (iii) the clinical significance of seminal vesicle cysts in ADPKD remains to be defined.

- Abstract
Fast spin-echo sequences was compared with conventional spin-echo sequences at 0.5 Tesla, in 130 patients who attended for routine brain MRI. Artefacts and contrast behaviour of anatomical structures and lesions were assessed visually and quantitatively by contrast-to-noise ratios. The difference between conventional spin-echo and fast spin-echo in contrast in intracerebral tumors and infarcts was not found to be significant statistically. Small amounts of haemosiderin and calcifications could not be seen on fast spin-echo images especially in T2 weighted. Flow artefacts were considerably reduced on fast spin-echo images. Motion artefact was considerably increased on dual-echo fast spin-echo sequences. There were no statistical differences between the results of the visual findings and between those of CNR values except for contrast between CSF and white matter and between haemoatoma and background in T2 sequences. Our results suggest that by virtue of the shorter acquisition time, diagnostic reliability and reduced flow artefact single-echo FSE sequences should be preferred to dual-echo CSE sequences in routine brain MRI at 0.5 Tesla.
