PurposeMultidisciplinary tumor boards (MTBs) have become commonplace. The use, attendance, and function of MTBs need continued assessment and improvement.MethodsWe prospectively recorded and assessed all cases presented at MTBs between October 2013 and December 2014. Data were collected before and during each MTB. Data were analyzed using SPSS for Windows version 23 (SPSS, Chicago, IL).ResultsFive hundred three cases were presented: 234 cases (46%) at GI cancer MTBs, 149 cases (29.6%) at breast cancer MTBs, 69 cases (13.7%) at thoracic/head and neck cancer MTBs, and 51 cases (10.7%) at neuro-oncology MTBs. A total of 86.7% of MTB cases were presented to make plans for management. Plans for upfront management were made in 67% of the breast cancer cases, 63% of GI cases, 59% of thoracic/head and neck cases, and 49% of neuro-oncology cases. Three hundred ninety-four cases (78.3%) were presented by medical oncologists, whereas only 74 cases (14.7%) were presented by surgeons, and 10 cases (2%) were presented by radiation oncologists. The majority of MTBs, with the exception of the neurosurgery MTBs, were led by medical oncologists. Surgeons presented the least number of cases but attended the most, and their contributions to discussions and decision making were essential.ConclusionMTBs enhance the multidisciplinary management of patients with cancer. Upfront multidisciplinary decision making should be considered as an indicator of benefit from MTBs, in addition to changes in management plans made at MTBs. Increasing the contributions of surgeons to MTBs should include bringing more of their own cases for discussion.
Objectives. The aim of this study is to demonstrate the various imaging appearances of stromal fibrosis on mammography, ultrasound, and magnetic resonance imaging (MRI). Material and Methods. This study included 75 female patients who presented to the American University of Beirut Medical Center between January 2010 and October 2015 for breast imaging. 66 (88%) patients obtained a mammogram, 71 (95%) had an ultrasound, and 6 (8%) had an MRI. Patients included had stromal fibrosis proven on biopsy. Results. The most common finding on mammogram was calcifications which was present in 14 (21%) patients, while on ultrasound it was a mass which was present in 61 (86%) patients. A mass was detected on MRI in 2 (33.5%) patients. Most lesions detected had benign findings such as masses with circumscribed margins. We had a follow-up for 53 (71%) patients with an average follow-up interval of 28.5 months (range: 5 – 70). Increase in size of the index lesion was noted in only 2 patients; upon rebiopsy, pathology results read stromal fibrosis for one lesion and fibroadenoma for the other. The remaining lesions were either stable or decreased in size. The higher detection rate of a mass on ultrasound was statistically significant (p<0.001) in comparison to that of mammography. Conclusion. Stromal fibrosis can have various presentations on imaging from benign to suspicious for malignancy features. In the case of accurate targeted biopsy, when stromal fibrosis is diagnosed, the result can be considered concordant. Therefore, such lesions can be followed up by imaging to document stability and confirm benignity.
A hyperechoic breast lesion must not always be assumed to be benign. Instead, a full sonographic assessment according to the American College of Radiology Breast Imaging Reporting and Data System descriptors is needed for correct characterization and avoidance of misdiagnosis.
Loss of reduction remains an important problem after treatment of distal radius fractures, whatever the type of bone fixation. We assessed retrospectively the rate of secondary displacement after external fixation of distal radius fractures in order to identify possible risk factors for instability. We reviewed the pre-operative and serial post-operative radiographs of a retrospective series of 35 distal radius fractures treated by bridging external fixation. When classified according to the Société Française d'Orthopédie et Traumatologie (SOFCOT) criteria, the rate of secondary displacement was 48.5%. At final follow up, the reduction was anatomical in 12% and acceptable in 83%. There was malunion in 5%. The loss of reduction concerned primarily the distal radius palmar tilt and was moderate. No correlation was found with age, gender, type of fracture, degree of initial displacement, associated ulnar fracture, or seniority of the treating surgeon.
The teaching role of radiology residents has seldom been evaluated, and little is known about how teaching skills of radiology residents evolve throughout their training in the absence of formal teaching guidance. Our objective is to identify residents' characteristics correlating with better teaching and compare teaching characteristics of junior and senior residents. Method: All seven medical schools in Lebanon were involved in this multi-centric study. A self-assessment questionnaire was sent to sixty-nine radiology residents and filled anonymously. Fifty-seven (83 %) responses were received and represent the study population. Data analysis was based on factors correlating with overall teaching effectiveness. A comparison of senior and junior residents' responses was also performed. Results: Overall teaching effectiveness correlated with better knowledge, technical skills, clinical judgment, communication skills, identification and correction of learning problems, and importantly providing and receiving feedback. Senior residents rated themselves significantly better than juniors in "knowledge related to radiology" and in "technical skills" but not in "overall teaching effectiveness". Seniors did not agree on the statement "medical students make my clinical responsibilities easier". Although not reaching statistical significance, seniors showed a trend towards improving teaching skills. Conclusions: Overall teaching effectiveness is correlated with the adoption of proper skills and techniques. Despite the lack of formal teaching guidance, senior radiology residents are improving their techniques as teachers but still face difficulties in several domains.
HR detected primary breast lesions and metastatic LNs missed on SR, which led to change in staging and management. In addition, HR images provided higher SUVmax, which enabled a more comfortable localization, especially when SR presented borderline values. Finally, HR images decreased the number of gray zone lesions, especially in axillary LN detection.
Anatomical variations of the digestive system arteries are important due to their clinical significance. However, anomalies in the inferior mesenteric artery (IMA) are the least common compared with the celiac trunk and superior mesenteric artery. This report describes the case of a 67-year-old man with an extremely rare variant in which the IMA arises from the left common iliac artery, and the ipsilateral external iliac artery has a corkscrew pattern. These findings were depicted during computed tomography angiography of the abdomen and pelvis. This case is the first report of such a variation associated with a left external iliac artery turning into a double loop before forming the femoral artery. The embryological and clinical significance of such an anomaly are discussed.
