Feel It, See It, Get It: Is Internal Medicine Residents' Use of Ultrasound in Lumbar Puncture Associated With Higher Success Rate?

Introduction:  Multiple emergency medicine and anesthesiology research studies suggest that ultrasound (US) is potentially useful in assisting with needle insertion in a lumbar puncture (LP). However, little is known about its value when utilized by internal medicine (IM) residents. The objective of this study is to examine whether the use of ultrasound in LPs performed by internal medicine residents is associated with a higher success rate than the traditional palpation method.

Combined Endosonographic Mediastinal Lymph Node Staging in Positron Emission Tomography and Computed Tomography Node-Negative Non-Small-Cell Lung Cancer in High-Risk Patients.

Positron emission tomography (PET) with computed tomography (CT) is routinely utilized to investigate lymph node (LN) metastases in non-small-cell lung cancer. However, it is less sensitive in normal-sized LNs. This study was performed in order to define the prevalence of mediastinal LN metastases discovered on combined endosonography by endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS) fine needle aspiration in patients with a radiologically normal mediastinum.

Breast cancer survival among South Asian women in California (United States).

Background: Very little is known about cancer survival patterns among the growing South Asian community in the United States.

Methods: Breast cancer survival patterns were evaluated among South Asians using California Cancer Registry data from 1988 to 1998, and breast cancer survival among South Asians was compared to non-Hispanic Whites and other Asian subgroups. The analysis included all female, invasive, histologically confirmed breast cancer cases diagnosed from 1988 to 1998.

Cancer incidence in the south Asian population of California, 1988-2000.

Background: Although South Asians (SA) form a large majority of the Asian population of U.S., very little is known about cancer in this immigrant population.
