Chest Radiography and Echocardiography Predictors of Early Hemodialysis Catheter Dysfunction  [PDF]
Kirsteen Burton, Jeremy O'Brien, Dheeraj Rajan
Open Journal of Radiology (OJRad) , 2012, DOI: 10.4236/ojrad.2012.23011
Abstract: Purpose: To determine whether radiographic heart morphology and echocardiography findings were associated with early central venous catheter (CVC) failure in hemodialysis patients. Materials & Methods: All hemodialysis catheter insertions between 1996-2007 were captured in a combined nephrology radiology database. Factors were identified that may be associated with early catheter failure. Factors examined included: echocardiography findings, radiographic evidence of flattened heart border, boot-shaped heart and left ventricular hypertrophy as well as patient comorbidities and peri-procedural characteristics. Results: Of the 132 CVC failures in 132 patients, 67 (50.8%) occurred within 30 days of insertion. Early CVC failure was more likely to occur in patients who had insertions from the left side (?2, p = 0.020) and with catheter tip position outside the cavoatrial junction (?2, p = 0.040). CVC failure rates also differed by year of placement (?2, p < 0.01), if the patient had evidence of left ventricular hypertrophy (?2, p = 0.030), left systolic dysfunction (?2, p = 0.030), and hypokinetic right wall mechanics (?2, p < 0.01). Conclusion: Radiographic findings of left ventricular hypertrophy and echocardiography findings of left systolic dysfunction were found to be associated with early failure.
Smartphone Applications for the Radiologist  [PDF]
Hasanein Al-Hasani, Hamid Abboudi, Tishi Ninan, Behnam Shaygi, Carl Roobottom
Open Journal of Radiology (OJRad) , 2013, DOI: 10.4236/ojrad.2013.34037
Abstract:

Smart phone applications (apps) for radiologists are on the rise. Not only do they assist the radiologist in reference to information but they can also aid in their day-to-day functioning too most notably through image viewing apps known as Digital Imaging and Communications in Medicine (DICOM) viewers. These kinds of apps signal a transition towards an increasingly mobile medical environment in what could be an exciting but cautious time for radiologists as these apps are not without their own concerns. In this review we provide basic information on how to create an app, highlight the current state of play of pivotal radiology apps and discuss the legal issues surrounding them.

Radiological Monitoring of Hip Replacements in Sickle Cell Disease Patients: Report of 31 Cases  [PDF]
Zouzou Ange Eric, Gnaoulé Debato Tina, Kouassi Bonfils, N’dja Ange Patrick, Kanga Alexis, Vanga Marius, Konan Alexis, Gbazi Gogoua Casimir
Open Journal of Orthopedics (OJO) , 2016, DOI: 10.4236/ojo.2016.610039
Abstract: Aim: The objective of the study was to report the progressive complications of hip joint disease in a population of sickle cell. Materials and Methods: A descriptive and retrospective study from 2002 to 2008: A case of 31 sickle cell subjects having presented an advanced osteonecrosis of the femoral head. All the patients benefited from an arthroplasty in adulthood with a radiographic monitoring in immediate post operative before and after one year. The sickle cell subjects were compared to a non sickle cell control group of 37 patients according to the same criteria. The analysis had included considerations of the environment and the position of the prosthetic parts, as well as additional modifications. The types of complications and the moment at which they occur were indexed and analyzed using a statistical test of FISHER with a threshold of significance level p < 0.05. Results: The average age of sickle cell patients was 35 years and non sickle cell disease sufferers, 51, with a male predominance. Indications for surgery were dominated by coxarthroses, 31 cases (100%) in sickle cell disease sufferers and 17 cases (46%) among the control group. All our patients underwent a radiological control in the immediate postoperative. They were fewer between 6 months and 1 year (19%). The immediate complications were dominated by fractures 2 cases in non sickle cell disease sufferers. The complications before one year were marked by a predominance of dislocation, 3 cases in the non sickle cell population against 2 cases in sickle cell population. The loosening were the most observed complications in both populations after a year and more (5 cases in sickle cell disease sufferers and 6 cases in non sickle cell disease sufferers). Conclusion: The evolutionary complications of joint replacements in sickle cell subjects are not more frequent than in non sickle cell subjects.

Foramen Magnum Orientation and Its Association with Cervical Lordosis: A Model for Reconstructing Cervical Curvature in Archeological and Extinct Hominin Specimens  [PDF]
Ella Been, Sara Shefi, Lisa Raviv Zilka, Michalle Soudack
Advances in Anthropology (AA) , 2014, DOI: 10.4236/aa.2014.43017
Abstract:

The cranial base is located at a critical intersection between the vertebral spine, the brain, the respiratory system and the mastication apparatus. Therefore it can provide an insight into the evolution of the head and neck in functional and phylogenetic contexts. However, the relationship between cranial base anatomy and cervical spine alignment has not been explored deeply. Therefore the aim of this research is to study the relationship between the orientation of the foramen magnum and the degree of cervical lordosis. Based on this relationship we developed six models which enable reconstruction of the cervical lordosis angle in archeological material and in extinct hominins. 74 adult lateral cervical radiographs were examined. The orientation of the foramen magnum and the angle of the cervical lordosis were measured on each radiograph. Foramen magnum orientation positively correlates with cervical lordosis angles: moderate to high correlation was found between foramen magnum orientation and the total cervical lordosis (0.716 < r < 0.612); moderate correlation was also found between foramen magnum orientation and the upper cervical lordosis (0.626 < r < 0.562); and only weak correlation was found with the lower cervical lordosis (0.306 < r < 0.101). Assuming that the positive correlation between foramen magnum orientation and cervical lordosis can be applied to all bipedal hominins, cranial base morphology can provide an insight to the degree of the cervical lordosis of archeological material and of extinct hominin.

Multifocal Chest Wall Hamartoma: A Rare Congenital Anomaly  [PDF]
Abhilasha Jain, Sharad Jain, Jayesh Patel, Anil Vasoya, Swati Gaba
Open Journal of Radiology (OJRad) , 2017, DOI: 10.4236/ojrad.2017.74031
Abstract: Chest wall hamartoma is a very rare tumour with benign course and distinct clinical, radiological, and histopathological characteristics. The lesion develops during foetal life and is present at or shortly after birth. It should be kept in differential diagnosis of complex chest wall masses diagnosed during antenatal ultrasound. CT thorax is useful for appreciation of detailed anatomy, characterization of the congenital abnormality and for surgical planning. Histopathology is used for the confirmation. Accurate diagnosis of mesenchymal hamartoma is important since many chest wall masses in children are malignant. We report a rare case of multifocal chest wall hamartoma in an infant who presented with multiple bilateral complex chest wall masses in which characteristic radiological and histopathological features led to the diagnosis of hamartoma, which was successfully treated with surgery.
