    ABSTRACT: To determine the frequency of BI-RADS category 3 nonpalpable masses detected using only sonography (US) and the malignancy rate among these lesions. Second, to validate a proposed short-term follow-up regimen based on long-term observational results. This prospective cohort study was conducted between September 2003 and April 2010. We conducted a 2-year short-term follow-up protocol composed of five US examinations at 3-month intervals for the first 6 months, and at 6-month intervals for the next 18 months, followed with age-appropriate screenings. Biopsy was recommended for the masses increasing in size and with changing imaging features. The frequency of category 3 nonpalpable masses detected only on US in 11,373 consecutive women was 5.3%. Of 562 lesions found in 451 women, 394 (70.1%) remained stable during the short-term and subsequent follow-up. Seventy-four (13.1%) masses showed interval regression and 79 (14.0%) showed interval progression. The malignancy rate was 0.3% (2 of 562), with about 85% of interval changes occurring within the first 2 years. The negative predictive value of US in the detection of cancer was 99.6% (95% CI, 98.7-99.9). The mean follow-up time was 65.5 ± 8.7 months. The frequency of BI-RADS 3 nonpalpable masses detected using sonography alone was 5.3%. During follow-up, the majority of interval changes occurred within the first 2 years. Because these masses have a very low malignancy rate, a 2-year follow-up instead of immediate biopsy is an appropriate option.

    ABSTRACT: The purpose of this study was to determine the anatomic relation of the neural structures posteriorly crossing the ankle by use of classical ankle arthroscopy posterior portals and hindfoot endoscopy portals. The effect of ankle and hindfoot motions on portal-nerve distance was also determined. This study included 20 feet and ankles in 20 adult volunteers who had no complaints regarding their ankle joints. To obtain 6 fixed positions of the ankle and hindfoot (neutral-neutral, neutral-varus, neutral-valgus, dorsiflexion-neutral, dorsiflexion-varus, and dorsiflexion-valgus) during magnetic resonance imaging examination, feet were positioned in a polycaprolactone splint that was shaped before examination. Magnetic resonance imaging examinations were performed at all 6 positions, and the shortest distance between the sural and posterior tibial nerves to the portals was measured at 2 different levels. The mean distance between the posterior tibial nerve and the posteromedial portal was 16.5 +/- 5.6 mm and that between the sural nerve and the posterolateral portal was 13.1 +/- 3 mm at the hindfoot portal level. At the level of the posterior ankle arthroscopy portal, the mean distance from the posterior tibial nerve to the posteromedial portal line was 13.3 +/- 4.6 mm and that from the sural nerve to the posterolateral portal line was 9.7 +/- 2.9 mm. The differences in distances were statistically significant (P < .001) according to the paired t test. We determined that the sural nerve approached the posterolateral portal in the dorsiflexion-varus (P = .026), dorsiflexion-valgus (P = .014), dorsiflexion-neutral (P < .001), and neutral-varus (P = .035) positions, and all differences were statistically significant. We found that the posterior medial and lateral portals created at the level of the tip of the fibula as described by van Dijk et al. while the foot was in a neutral-neutral position provided the greatest margin of safety. We found no advantage of placing the ankle and hindfoot in different positions to avoid neurologic complications. These findings suggest that neurovascular structures draw away from the posterior portals of ankle arthroscopy distally; by lowering the level of portals toward the tip of the fibula and positioning the foot at neutral, arthroscopic surgeons will decrease the risk of iatrogenic lesions.

    ABSTRACT: Accelerated atherosclerosis is the major cause of mortality in patients on chronic haemodialysis (HD). Increased oxidative stress might be the major factor leading to high cardiovascular mortality rate in HD patients. The aim of our study was to clarify effects of uraemia and dialysis on oxidative stress parameters and explore the relation between oxidative stress markers and carotid artery intima-media thickness (CIMT) as an indicator of atherosclerosis. Twenty chronic HD patients, 20 predialytic uraemic patients and 20 healthy subjects were included in the study. Serum thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCO) and nitrite/nitrate levels were determined as oxidative stress markers. Serum vitamin E, plasma sulfhydryl (P-SH), erythrocyte glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities were measured as antioxidants. CIMT was assessed by carotid artery ultrasonography. Both chronic HD and predialytic uraemic patients had enhanced oxidative stress indicated by higher levels of nitrite/nitrate, TBARS and PCO, and lower levels of P-SH, SOD, CAT and GPx compared to controls. HD patients had significantly higher CIMT and nitrite/nitrate while significantly lower P-SH,vitamin E, SOD, CAT and GPx compared to predialytic uraemic patients. There was a significant positive correlation between CIMT and TBARS (r = 0.38, P = 0.003) and nitrite/nitrate levels (r = 0.41, P = 0.001), while there was a significant negative correlation between CIMT and SOD (r = -0.35, P = 0.01), CAT (r = -0.65, P < 0.001) and P-SH levels (r = -0.50, P < 0.001). A linear regression analysis showed that TBARS were still significantly and positively correlated with CIMT (P = 0.001), while CAT and P-SH were significantly and negatively correlated with CIMT (P = 0.002 and P = 0.048, respectively). HD exacerbates oxidative stress and disturbances in antioxidant enzymes in uraemic patients. We propose that serum TBARS and nitrite/nitrate can be used as positive determinants, while erythrocyte SOD, CAT and P-SH may be used as negative determinants of atherosclerosis assessed by CIMT in uraemic and HD patients.

    ABSTRACT: Oxidative stress is a new risk factor for atherosclerosis. Increased oxidative stress in hemodialysis (HD) patients may arise from uremia-associated metabolic/humoral abnormalities and bioincompatibility of dialysis. Patients with diabetes mellitus (DM) may be subject to an additional risk. Respective influences of uremia, diabetes, and HD duration in accelerated atherosclerosis and oxidative stress have not been clarified yet. The study was performed on 24 nondiabetic HD patients, 23 diabetic HD patients, 20 stages 3 to 4 chronic kidney disease patients, and 21 diabetic patients without overt nephropathy. Carotid intima-media thickness, a surrogate of atherosclerosis, was measured by high-resolution B-mode ultrasonography. Oxidant status was determined by lipid peroxidation as expressed by malondialdehyde (MDA); antioxidant status was determined by superoxide dismutase, catalase, glutathione peroxidase, reduced intracellular glutathione, and plasma thiol. Intima-media thickness (IMT) was higher in patients undergoing HD but not different between nondiabetic HD patients and diabetic HD patients. No correlation was found between the duration of HD and intima-media thickness. Antioxidants were generally lower in HD patients. Intima-media thickness was positively correlated with MDA and negatively correlated with plasma thiol. Among other risk factors, only age was correlated with intima-media thickness. Increased carotid IMT in HD patients is independent of duration of HD or diabetes status. Age and MDA are the significant predictors of carotid IMT. Increased oxidative stress due to impaired antioxidant mechanisms, particularly reduced plasma thiol redox potential, may account for accelerated atherosclerosis in high-risk patients with chronic kidney failure and/or DM.

    ABSTRACT: Both diabetes and hemodialysis (HD) are associated with increased oxidative stress. The aim of this study was to clarify the effect of maintenance HD on oxidative stress parameters in diabetic patients and to explore any relation between carotid artery intima-media thickness (CIMT) and oxidative stress markers. Twenty Type 2 diabetic patients undergoing chronic maintenance HD, 20 type 2 diabetic patients with normal renal function, and 20 age- and sex-matched healthy subjects were included. Serum thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCO), and nitrite/nitrate levels were determined as oxidative stress markers. Serum vitamin E, plasma sulfhydryl (P-SH), erythrocyte glutathione (GSH) levels, and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities were measured as antioxidants. CIMT was assessed by carotid artery ultrasonography. Both diabetic patient groups had enhanced oxidative stress indicated by higher levels of TBARS, PCO, and nitrate/nitrite and lower activities of SOD, CAT, and GPx compared to controls. Diabetic patients undergoing HD had significantly higher CIMT (P=.001) and higher levels of nitrite/nitrate (P=.05), PCO (P=.03), and GSH (P=.04) but significantly lower levels of P-SH (P<.001), serum vitamin E (P=.04), SOD (P=.02), CAT (P=.001), and GPx (P=.006) compared to diabetic patients with normal renal functions. There were significant negative correlations between CIMT and SOD (r=-0.50, P<.001), CAT (r=-0.41, P=.003), and P-SH levels (r=-0.51, P<.001) and significant positive correlation between CIMT and nitrite/nitrate levels (r=0.41, P=.003) and TBARS (r=0.35, P=.02). Linear regression analysis showed TBARS was significantly and positively correlated with CIMT (P=.04), while SOD and P-SH were significantly and negatively correlated with CIMT (P=.05 and P=.02, respectively). Hemodialysis exacerbates oxidative stress and disturbances in antioxidant enzymes in diabetic patients. Serum nitrite/nitrate and TBARS can be used as positive determinants, while erythrocyte SOD, CAT activities, and P-SH level can be used as negative determinants of atherosclerosis assessed by CIMT in diabetic patients.

    ABSTRACT: OBJECTIVE: The purpose of our study was to describe the initial and long-term imaging findings in hepatobiliary fascioliasis. CONCLUSION: Most patients with fascioliasis have typical hepatobiliary imaging findings. It is important to know that residual fibrotic or necrotic foci may remain for years after cure. Long-term complications are rare in fascioliasis, and malignancy or cirrhosis related to the disease has not been observed.

    ABSTRACT: To evaluate the long-term results of percutaneous imaging-guided treatment of hydatid liver cysts. Sixty patients with 77 hydatid liver cysts underwent percutaneous treatment with ultrasonography (US) or computed tomography (CT) guidance. Absolute alcohol and hypertonic saline were used for sclerosing the cysts after aspiration. Prophylactic albendazole treatment was given before and after the procedures. Follow-up US and CT were obtained periodically, and changes in cyst morphology were recorded. Minimum follow-up period for the patients included in this study was 12 months. Serological correlation was also available for a group of patients. The outcome of the procedures were categorized into five groups based on morphological changes observed by imaging. Procedures were regarded as successful in 80% and unsuccessful in 20% of patients. Failures most often occurred with type III cysts; less than half (39%) of the total type III cysts had a successful outcome. On the other hand, all type I cysts ended up with cure. Anaphylaxis, pneumotorax and severe pain interrupting the procedures were also among the reasons of failure. Percutaneous aspiration, injection and reaspiration (PAIR) of types I and II hydatid liver cysts is effective and safe in the long-term. Surgery should no longer be regarded as the first choice treatment in all hydatid liver cysts but should be reserved for type III and certain active type IV cysts.

    ABSTRACT: PURPOSE Recently percutaneous dilatational tracheostomy(PDT) has become an important interventional procedure which is performed in prolonged ventilated patients in Intensive Care Units (ICU). The purpose of this study is to evaluate the utility of pre-incisional ultrasound (US) control of the neck to avoid complications and to reveal the advantages of performing PTD under sonography guidiance. METHOD AND MATERIALS In 6 months period, 96 ICU patients underwent PDT were included and we devided the patients into two groups at random. In group A (n=44, mean age 56 years) US control of the puncture area and the adjacent anatomical structures was made. Possible causes of complications such as short neck, altered tracheal anatomy, subcutaneous vascularity, thyroid nodules, endotracheal tube’s cuff level, highly localized innominate artery were determined. With US imaging, endotracheal tube’s cuff drawn back to a safe level to avoid perforation and seeking needle's insertion point was checked according to the midline and tracheal rings. If misplacement was detected, the puncture level was changed. In group B (n=52, mean age 59 years), the procedure was completed without US examination. Physical landmarks used to locate the insertion level. RESULTS In group A, first insertion level was corrected in 16 patients according to the US control. In five cases US aided puncture was prefered initially by clinician be cause of suboptimal conditions (short neck, massive goitre etc). The acute complications were; minimal hemorage in 3 patients and cuff perforation of endotracheal tube in 1 patient. In group B, acute complications were; major bleeding in 2 patiens (compressed wound-dressing and cotherization were used to control bleeding), minimal hemorage in 5 patients and cuff perforation of endotracheal tube in 5 patient. CONCLUSION Bedside PDT can be safer and more effective method by the use of ultrasound pre- and peroperatively. In this study, there is no significance statistical diffarance between the complication results but it’s suggested to enlarge the series. Acute complications of PDT can be reduced with US guidiance especially when the physical landmarks are insufficient to carry out the technique.

    ABSTRACT: Visceral larva migrans (VLM) most commonly occurs as a febrile disease of childhood particularly affecting children between 1 and 7 years of age. Pulmonary, dermatological, hepatic, lymphatic, cardiac, rheumatological and neurological manifestations may occur. VLM seems to be a rare disease in adults. We report the imaging findings of a woman with hepatic toxocariasis. Ultrasonography showed a solitary hepatic lesion measuring 4 x 3 cm, displaying a hypoechoic-heterogeneous pattern with ill-defined borders and distal acoustic enhancement, located in the right sub-diaphragmatic area. Two enlarged periportal lymph nodes and moderately dilated intrahepatic biliary ducts were also noted. The probability of toxocariasis was discussed, based on sonographic and biopsy findings, and the final diagnosis was confirmed by a specific ELISA test. In summary, a clinical picture of cholestasis initially resembling hepatitis or malignancy should be further evaluated by imaging techniques, and the ultrasound examiner should be familiar with the possible findings of hepatic toxocariasis, which consist of focal ill-defined hepatic lesions, hepato-splenomegaly, biliary dilatation, sludge and periportal lymph node enlargement.

    ABSTRACT: The aim of this cross-sectional study was to estimate the prevalence and risk factors of symptomatic knee and distal interphalangeal (DIP) joint osteoarthritis (OA) in the elderly (> or =50 years of age) urban population of Antalya, Turkey. According to the 1997 national census, Antalya's population was 508,840. By random cluster sampling, 655 individuals aged 50 years or more were interviewed face-to-face and subjected to structured interviews regarding knee pain, worsening pain on exertion, and the gelling phenomenon. They were also asked about performing namaz (a fundamental act of worship in Islam performed five times a day), smoking, type of residence, type of toilet, work style, and duration of walking per day. They were also questioned about swelling in DIP joints. In the case of suspicion of knee OA, the individuals were invited to the hospital for further evaluation by physical examination and direct roentgenogram. The diagnosis of knee OA was based on clinical or clinical and radiographic findings. The prevalence of symptomatic knee OA was determined as 14.8% in the population aged 50 years or over. Advanced age, female sex, namaz, and type of residence were found to be associated with knee OA. The rate of symptomatic knee OA was significantly lower in smokers and those walking more than 2 h per day. Female sex was also strongly associated with OA DIP joints. OA of DIP joints was found significantly associated with symptomatic knee OA. The latter is a major health problem in the elderly population, especially in about one fourth of women aged 50 years or over. These data suggest that advanced age, female sex, and type of residence are risk factors.

    ABSTRACT: To compare the effectivity of low (0.35 T) and high (1.5 T) field magnetic resonance imaging units in detecting meniscal tears. Forty-eight knee MR imaging examinations performed in low field MR unit and 76 examinations performed in high field unit were retrospectively evaluated. MR results were compared with arthroscopy findings in all patients. For medial meniscus tears, sensitivity, specificity and accuracy values were 93.7%, 87.5% and 91.6%, respectively in the low field unit. For lateral meniscus tears, these values were 87.5%, 95.0% and 93.7%, respectively. In the high field unit (1.5 T), sensitivity, specificity and accuracy for the detection of medial meniscus tears were 96.6%, 88.2% and 94.7%, respectively. For lateral meniscus tears, these values were 71.4%, 98.5% and 96.0%, respectively. There was no statistically significant difference between high and low field units in the detection of medial and lateral meniscus tears. We think that low field MR units are as effective as high field units in the evaluation of meniscus tears.

    ABSTRACT: To investigate whether informing patients about mammographic compression changed the anxiety and pain that they experience during mammography. Five hundred and one patients were enrolled in the study. Two hundred and fifty seven (51.3%) were informed before the procedure by written forms explaining the necessity of compression. The remaining 244 (48.7%) didn't get any pre-procedural information. All participants completed demographic form and Spielberger's State Anxiety Inventory while they were waiting for mammography. They marked the level of pain due to compression on a 100-mm visual analog scale (VAS) after the procedure. Chi square, Pearson's correlation and Student's t tests were used for statistical analyses. We didn't find any significant difference between the anxiety scores of the informed (41.4+/-7.9) and uninformed (40.9+/-7.7) women, but the pain level was significantly lower in the informed group (16.5+/-22.4) than in the uninformed group (24.5+/-28.1). There was no statistically significant relationship between the anxiety and pain levels. Women who had recently felt tense and nervous or had a fear of breast cancer diagnosis had higher anxiety levels. Our data shows that informing patients about examination decreases the level of pain due to mammographic compression, but does not alter the anxiety level. The main cause of anxiety appears to be the fear of a malignant diagnosis. Any intervention to decrease this fear may increase the compliance rates for screening mammography.

    ABSTRACT: Our objective was to describe MR imaging findings of liver lesions in human fascioliasis. The MR imaging of the liver was performed in 29 patients with fascioliasis. Seventeen patients were women and 12 were men, with a mean age of 47.5 years (age range 17-75 years). Hepatic lesions were grouped into five types based on their signal characteristics. Three patients had normal imaging findings. One or more lesions were observed in the other 26 patients. The lesion types and the frequency of appearances were as follows: hyperintensity of the liver capsule on T2-weighted images (n=16, 55.2%); ill-defined slightly hyperintense areas on T2-weighted images (n=18, 62.1%); lesions which were hypointense on T1-weighted and hyperintense on T2-weighted images (n=10, 34.5%); hypointense on T1-weighted images and centrally hypo- or hyperintense, surrounded by peripherally less hyperintense area on T2-weighted images (n=4, 13.8%); and hypointense foci or ill-defined hypointense areas on T1- and T2-weighted images (n=10, 34.5%). We describe the MR imaging features of the disease. Our findings may help the differential diagnosis in which fascioliasis should be added to the list.

    ABSTRACT: To evaluate orbital blood flow velocities with Doppler sonography in patients with acute unilateral optic neuritis. Orbital Doppler sonography was performed in 20 patients with acute unilateral optic neuritis. Optic neuritis was diagnosed by a neurologist on the basis of clinical presentation, presence of decreased visual acuity, and assessment of visual evoked potentials. The peak systolic and end diastolic velocities and the resistive index were measured in the ophthalmic and central retinal arteries of both orbits. The values obtained from affected and unaffected orbits were compared by using the paired t test. The peak systolic and end diastolic velocities in the ophthalmic artery were significantly increased in the affected orbits (for peak systolic velocity P <.001, for end diastolic velocity P <.05). Resistive indexes in the ophthalmic arteries did not differ (P >.05). The difference between the peak systolic and end diastolic velocities and resistive indexes in the central retinal arteries of affected and normal eyes was not statistically significant (P >.05). Peak systolic and end diastolic velocities in the ophthalmic artery are increased in patients with acute optic neuritis.

    ABSTRACT: To investigate blood flow velocity changes, pulsatility and resistivity index values of orbital vessels in Behçet's disease with or without ocular involvement (groups I and II) and healthy volunteers (group III). Twenty-five eyes in the first group, 24 eyes in the second group and 24 eyes in the third group were examined by using color Doppler imaging. Peak systolic and end-diastolic blood flow velocity measurements, pulsatility and resistivity index values were measured in ophthalmic, central retinal, nasal and temporal ciliary arteries and the central retinal vein. The end-diastolic blood flow velocity measurements in all arteries were significantly higher in groups II and III than in group I, but resistivity and pulsatility indexes of all arteries were higher in group I than the other two groups. There was no significant difference in blood flow velocity of the central retinal vein in the three groups. Detection of increased vascular resistance of orbital vessels may predict the diagnosis of ocular involvement in Behçet's disease.

    ABSTRACT: The purpose of this study is to describe the ultrasonographic (US), computed tomographic (CT), and magnetic resonance imaging (MRI) findings in fascioliasis and to emphasize the impact of radiology in diagnosis. Radiologic findings in 23 consecutive patients with fascioliasis were prospectively recorded. All patients had at least one US and CT examination, and 10 of them were studied by MRI. All diagnoses were confirmed by serologic methods. In the first three cases, initial diagnosis was reached by microscopic demonstration of the parasites' eggs in bile obtained by US-guided gallbladder aspiration. In the hepatic phase of fascioliasis, multiple, confluent, linear, tractlike, hypodense, nonenhancing hepatic lesions were detected by CT. On US, the parasites could be clearly identified in the gallbladder or common bile duct as floating and nonshadowing echogenic particles. MRI showed the lesions as hypo- or isointense on T1-weighted images and as hyperintense on T2-weighted images. CT findings in the hepatic phase and US findings in the biliary phase are characteristic of fascioliasis. Because clinical and laboratory findings of fascioliasis may easily be confused with several diseases, radiologists should be familiar with the specific radiologic findings of the disease to shorten the usual long-lasting diagnostic process.

    ABSTRACT: To evaluate the efficacy of ultrasound (US) guided percutaneous sclerotherapy in the pediatric population, 14 hydatid liver cysts (HLC) in eight male patients whose ages ranged between 6 and 16 years (mean 9.9 years) were treated. The maximum diameter was 110 mm. Albendazole was administered orally to all patients for 1 week before percutaneous treatment and for 3-6 months after the procedure to prevent dissemination of the disease. Cyst puncture was performed with 20 G Chiba needles using US guidance. More than one-half of the estimated cyst volume was aspirated, then 20% hypertonic saline (7 cysts) or sterile 96% alcohol (7 cysts) equivalent to one-third of the estimated cyst volume was injected into the cavity and left for 5-15 min. Finally, all the fluid in the cavity was reaspirated. Catheterization was not performed. Follow-up US examinations were performed every month during the first 6 months and every 3 months thereafter. The follow-up period ranged between 6 and 51 months (mean 15 months). No major complications were seen during or after the procedures. Two cysts in two patients completely disappeared. Volumes of the 11 cysts in five patients who were followed for 6-21 months were markedly reduced (22%-64% of the initial volume) and thick septations and solid debris-like structures were seen within the cyst cavities. There was no significant change in 1 cyst. US-guided percutaneous sclerotherapy is thus a safe and effective treatment of HLC in children.

    ABSTRACT: Our purpose was to determine the association between sonographically detected subacromial/subdeltoid (SA/SD) bursal and biceps tendon sheath effusions and arthrographically proven rotator cuff tears. Shoulder sonography reports and sonograms of 105 shoulders in 102 patients who also underwent arthrography were retrospectively reviewed for the presence of fluid within the biceps tendon sheath and SA/SD bursa. Reports and sonograms for 151 asymptomatic shoulders were also reviewed. Biceps tendon sheath effusion and/or bursal fluid were detected in 50 (48%) of 105 shoulders. Fifty-one patients had rotator cuff tears; 28 of them had effusions at 1 or both sites. The sensitivity, specificity, and positive predictive value (PPV) of biceps tendon sheath effusions for diagnosing rotator cuff tear were 35%, 74%, and 56%, respectively. For SA/SD bursal effusions, the sensitivity, specificity, and PPV were 8%, 94%, and 57%, respectively. For combined biceps tendon sheath and bursal effusions, the sensitivity, specificity, and PPV were 12%, 91%, and 54%, respectively. There was no statistically significant association between rotator cuff tears and effusions in the biceps tendon sheath, SA/SD bursa, or both. Among the 151 asymptomatic shoulders, 12 (7.9%) had biceps tendon sheath fluid, 5 (3.3%) had SA/SD bursal effusion, and 2 (1.3%) had both biceps tendon sheath and bursal effusions. The sonographic detection of intraarticular fluid, SA/SD bursal fluid, or both has a low sensitivity and PPV in the diagnosis of rotator cuff tears. Isolated intra-articular and/or SA/SD bursal effusions are not reliable signs of rotator cuff tear.
