Background Foreground
A 25 year-old female has been recently diagnosed with classical Hodgkin’s lymphoma (nodular sclerosing subtype). Staging reveals that she is a stage IIA with a 4.5 cm nodal mass in her neck and mediastinal nodes. Her hematologist recommends combined modality therapy (chemotherapy/radiation therapy). The patient has done some reading about therapy and is worried about the long term effects of radiation especially the risk of breast cancer.
Background Foreground
What is the pathophysiology of Hodgkin’s lymphoma?
Background Foreground
For a 25 year old female with stage IIA Hodgkin’s lymphoma, is combined modality therapy superior to chemotherapy alone?
Background Foreground
A 35 year-old patients presents to the ER with a right leg swelling x 3 days. The patient recently returned from a business trip in Malasia and therefore you suspect a deep vein thrombosis (DVT). It is the weekend and so the patient receives a CT angiogram that does not reveal any pulmonary embolism and the venous portion of the study does not reveal any above or below knee clots. That said, you are still convinced that the patient may have a lower limb DVT and so you ask for a lower limb doppler which requires the radiologist to come into the hospital in the middle of the night to perform the study. The radiologist is reluctant to come as the venous phase of the CT angiogram was negative.
Background Foreground
What diagnostic tests are performed for a DVT?
Background Foreground
Which of the following is more sensitive for detecting lower limb DVTs (both above and below knees): venous dopplers or CT angiograms?
