The results of this study suggest that MRI does not increase microleakage of amalgam restorations.

Results

In teeth with amalgam filling, there were no significant differences of occlusal and gingival surface microleakage after MRI exposure. Occlusal and gingival surface microleakages were also similar with and without MRI in teeth with bonded amalgam filling.

Materials and Methods

Class II cavities (3 mm width × 1.5 mm depth) with gingival margins ending 1 mm below the cementoenamel junction (CEJ) were prepared in 40 permanent molar teeth. The teeth were randomly divided into four groups. Cavities in the first and second groups were restored with dentin adhesive and amalgam (bonded amalgam), and those in the third and fourth groups with amalgam only. MRI was performed with the teeth specimens from the first and third groups. All specimens were then thermocycled at 5° to 55° C with a 30-second dwell time for 1000 cycles. The samples were then immersed in 0.5% methylene blue dye for 24 hours and sectioned longitudinally. Dye penetration at the occlusal and gingival margins was quantified by 15× stereomicroscopy. IBM SPSS Statistics ver. 21.0 (IBM Corp., Released 2012., IBM SPSS Statistics for Windows, Armonk, NY: IBM Corp.) and MS-Excel 2007 programs were used for statistical analyses and calculations. “nparLD” module was used for F2_LD_F1 design analysis at R program. P<0.05 was considered statistically significant.

Objectives

The aim of this study is to compare the effect of magnetic resonance imaging (MRI) on microleakage of class II bonded amalgam versus classical amalgam restorations.

Background

The effect of MRI on microleakage of amalgam restorations is an important health issue that should be considered. If MRI application causes increase of microleakage, amalgam fillings should be reassessed after MRI and replaced if necessary.

Our study shows in terms of figures that measurements of features of the temporal bone made from spiral CT scan images and those directly obtained during surgery are similar to an adequate extent.

Results

Twenty cases were included. In the three measurements performed in this study, only the first parameter (distance between the canal and the sigmoid sinus) was significantly different between the direct measurement made during surgery and that obtained from CT scans. There was no significant difference in the measurements of the distance between the dome of the lateral semicircular canal and the bone cortex, and the distance between the external surface of the incus and the surface of the bone cortex.

Objectives

This study compared findings from computed tomography images with those observed directly during ear surgery.

Patients and Methods

Patients with various pathologies of the ear who needed surgery were referred to an imaging center for a spiral CT scan of the temporal bone. The following parameters were measured by a radiologist and also later recorded by the surgeon during surgery: 1) The distance between the postero-superior border of the outer ear canal and the sigmoid sinus; 2) The distance between the dome of the lateral semicircular canal and the mastoid cortex; and 3) The distance between the external surface of the incus and the mastoid cortex.

Background

Accurate radiological assessment of the anatomical features of the temporal bone is crucial to prevent damage to vital elements in this area during surgery. Knowing the approximate location of specific temporal bone related landmarks in advance is very important for planning surgery.

Of the 53 neck dissection specimens, histopathology showed metastases in 16 cases. The overall accuracy of USGFNA, US and palpation was 96%, 68% and 70%, respectively. The specificity of USGFNA was superior to palpation and US alone. USGFNA had the highest sensitivity, predictive value and accuracy in detecting cervical metastases compared with other performed tests.

Conclusion

In our study, USGFNA was superior to palpation and US in detecting metastasis in clinically negative necks. This method can be recommended as a diagnostic tool in preoperative assessment of patients without palpable metastasis, but further investigations are needed before this modality could be considered as an alternative to elective neck dissection.

Background

In head and neck cancer patients, diagnosis of metastatic cervical adenopathy is essential for treatment planning and prognosis assessment. Treatment of patients with head and neck cancer with clinically negative cervical lymph node (N0) remains controversial. While routine neck treatment would result in overtreatment in many patients, observation may delay the diagnosis and decrease the patients’ survival.

Patients and Methods

Forty-two patients with head and neck cancer who underwent US and USGFNA prior to elective neck dissection were studied. Histopathologic findings of the neck specimens were compared with each diagnostic technique.

Objectives

To gain insights into the unclear questions regarding the value of diagnostic modalities in patients with N0 neck, this study was designed to compare the diagnostic efficacy of palpation, ultrasonography (US) and ultrasound-guided fine needle aspiration (USGFNA) in detecting cervical lymph node metastasis.

Diffuse large B cell lymphoma is the most common type of non-Hodgkin's lymphoma, representing nearly one-third of all cases. Any organ can be involved, making a diagnostic biopsy imperative. When the lungs are the involved organs, it is called primary pulmonary lymphoma (PPL). Hereby, we present a case of primary pulmonary lymphoma (PPL) that demonstrated a single large mass on chest CT and had metastatic skin lesions. The diagnosis of PPL was performed by histopathology and immunohistochemistry staining of the transthoracic lung biopsy and skin lesion specimens. This case highlighted an unusual and subtle clinical presentation, and the importance of new onset pulmonary symptoms and a large lung mass on chest X-ray. Review of the literature on the patient`s radiographic presentation revealed various findings, the most common of which were single or multiple nodular lesions in one or two lungs. It highlighted the fact that this diagnosis should be considered in all cases with a lung mass and skin lesions.

Intraclass correlation coefficient for left and right showed good to high reliability for the cross sectional area of lumbar multifidi (0.74 and 0.88, respectively) as well as the anterior-posterior dimensions of lumbar multifidi (0.89 and 0.91, respectively) and transverse abdomini thickness (0.73 and 0.85, respectively).

Conclusions

Rehabilitative ultrasonography is a reliable and non-invasive instrument to measure muscle thickness. The method used in this study is a reliable way to measure lumbar stabilizing muscles.

Objectives

The purpose of this study was to test the reliability of ultrasonography to measure muscle dimensions and to present a reliable method for measuring transverse abdominis and lumbar multifidus as stabilizing muscles of the lumbar spine.

Patients and Methods

Fifteen healthy participants (18-55 year olds) were evaluated by a radiologist using Sono made in Canada. (ES500) with two probes (50mm linear 7.5 MHZ and 70 mm curvilinear 3.5 MHz). The muscle thickness of transverse abdominis and the anterior-posterior diameter and cross sectional area of the LMF were measured. To determine within and between days reliabilities, second and third measurements were repeated with half an hour and one week intervals, respectively.

Background

Lumbar paraspinal muscles play an important role in providing both mobility and stability during dynamic tasks. Among paraspinal muscles, transverse abdominis and lumbar multifidus have been of particular interest as active stabilizers of the lumbar spine. These muscles may become dysfunctional in chronic low back pain (CLBP). Low back injury can result in muscle inhibition and control loss that cannot recover spontaneously, and specific exercises are required to stimulate their recovery.

The relationship between CAC found on dental panoramic radiographs and two CVA risk factors--hypertension and MI-- was significant. Therefore, it seems that detection of CAC on panoramic images of dental patients must be considered by dentists.

Results

Among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. In total, 52 patients (26%) had hypertension and four people (2%) had a history of MI. Eleven individuals among patients suffering from hypertension (21.2%) and three individuals among patients with a history of MI (75%) demonstrated CAC on dental panoramic images .

Patients and Methods

Panoramic images of 200 patients that were all women above 50 years of age (a population suffering from vascular diseases) were investigated. All panoramic images were provided under similar conditions in terms of the type of panoramic radiograph equipment, type of applied films and the automatic film processor. Then, the patients answered questions about MI history and taking antihypertensive drugs. We also measured the blood pressure of patients in two separate surveys. Data analysis was performed by SPSS statistical program. We used Exact Fisher test and Chi-Square test at a significant level of less than 0.05 to study the effect of these variables on the occurrence of carotid artery calcification.

Background

Carotid artery calcification may be related to cerebrovascular accident, which may result in death or physical and mental disabilities in survivors.

Objectives

Our purpose is to study the association of carotid artery calcification (CAC) on dental panoramic radiographs and two risk factors of cerebrovascular accident (CVA) including hypertension and myocardial infarction (MI).

Conclusions

The relationship between CAC found on dental panoramic radiographs and two CVA risk factors--hypertension and MI-- was significant. Therefore, it seems that detection of CAC on panoramic images of dental patients must be considered by dentists.

Results

Among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. In total, 52 patients (26%) had hypertension and four people (2%) had a history of MI. Eleven individuals among patients suffering from hypertension (21.2%) and three individuals among patients with a history of MI (75%) demonstrated CAC on dental panoramic images .

Patients and Methods

Panoramic images of 200 patients that were all women above 50 years of age (a population suffering from vascular diseases) were investigated. All panoramic images were provided under similar conditions in terms of the type of panoramic radiograph equipment, type of applied films and the automatic film processor. Then, the patients answered questions about MI history and taking antihypertensive drugs. We also measured the blood pressure of patients in two separate surveys. Data analysis was performed by SPSS statistical program. We used Exact Fisher test and Chi-Square test at a significant level of less than 0.05 to study the effect of these variables on the occurrence of carotid artery calcification.

en 10.5812/iranjradiol.21010 Diagnostic Accuracy of Secondary Ultrasound Exam in Blunt Abdominal Trauma Diagnostic Accuracy of Secondary Ultrasound Exam in Blunt Abdominal Trauma research-article research-article Background

In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial.

Objectives

To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma.

Patients and Methods

We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients.

Results

Primary ultrasound was performed in 372 patients; 61of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams.

Conclusions

Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid.

en 10.5812/iranjradiol.16958 Outcome of Retinoblastoma Following Limited Sessions of Intra-Arterial Chemotherapy in Iran Outcome of Retinoblastoma Following Limited Sessions of Intra-Arterial Chemotherapy in Iran research-article research-article Conclusions

Intra-ophthalmic artery melphalan is an effective treatment for advanced cases of retinoblastoma, with a reasonable level of success. In the short follow up period of this study, it appears that the primary cases showed better results in the control of tumor.

Background

The management of retinoblastoma remains a challenge to the multidisciplinary team, particularly as treatment affects not only visual outcomes, but also ocular retention and morbidity. Management of retinoblastoma has evolved over the past two decades.

Objectives

To report the result of intra-ophthalmic artery chemotherapy (IAC) for the treatment of refractory and advanced retinoblastoma tumors.

Patients and Methods

All patients who had failed to respond adequately to previous treatments and six naive patients with advanced retinoblastoma, receiving IAC between 2009 and 2012, were included in this institutional interventional case series. The patients received 1-2 treatments of IAC given 4-8 weeks apart. Complete response was defined as regressed tumor and complete disappearance of seeding clinically and partial response was defined as partial regression of the tumor with live parts of the tumor and/or lessening of seeds, but not complete disappearance of them clinically.

Results

A total of 24 eyes of 24 patients were treated with IAC during the study period. The mean age at the time of IAC was 38.9 months (14-120 months), and the mean follow-up was 16.8 months (3-36 months) after IAC. Tumor control was achieved in 14 eyes (58.3%). Type 3 (combined fleshy and calcified remnants) was the most common type of regression (37.5%). Complications included vitreous hemorrhage in nine eyes (37.5%), arterial occlusion in two (8.3%), cyclitic membrane possibly secondary to ischemia and tractional retinal detachment in one patient (4.2%), chorioretinal atrophy in three (12.5%) patients, and neovascular glaucoma in one eye (4.2%). In eight (33.3%) patients, no complication happened. Globe salvage was achieved in 62.5% of the cases. The success rate for naive patients was 84%. Sixty-seven percent of the cases received transpupillary thermotherapy and cryotherapy before IAC.

Conclusions

Intra-ophthalmic artery melphalan is an effective treatment for advanced cases of retinoblastoma, with a reasonable level of success. In the short follow up period of this study, it appears that the primary cases showed better results in the control of tumor.
