This diagnostic study evaluates the sensitivity and specificity of point-of-care ultrasonography performed by emergency medical practitioners in identifying retinal detachment, vitreous hemorrhage, and vitreous detachment among patients with ocular symptoms who present to the emergency department.

Between August 15 and September 15, 1980, an outbreak of infections due to adenovirus type 7b occurred at Children's Hospital and Health Center, San Diego, California. During that time, four of six patients infected with adenovirus type 7b died. All patients with hospital-acquired disease had underlying respiratory compromise. Cultures, adenoviral serology tests, and histories were obtained from 383 (93%) of the 410 hospital employees. All 11 people from whom adenovirus type 7 was cultured were nurses working in a unit with an infected patient. Seven other employees with negative cultures had a fourfold or greater rise in their adenoviral complement fixation titers. This outbreak demonstrates that adenovirus type 7 infections are capable of causing serious and potentially fatal disease in hospitalized patients and suggests that individuals with underlying respiratory diseases are especially at risk.

Growing evidence suggests that only a fraction of prostate cancers detected clinically are potentially lethal. An important clinical issue is identifying men with indolent cancer who might be spared aggressive therapies with associated morbidities. Previously, using microarray analysis we defined 3 molecular subtypes of prostate cancer with different gene-expression patterns. One, subtype-1, displayed features consistent with more indolent behavior, where an immunohistochemical marker (AZGP1) for subtype-1 predicted favorable outcome after radical prostatectomy. Here we characterize a second candidate tissue biomarker, hCAP-D3, expressed in subtype-1 prostate tumors. hCAP-D3 expression, assayed by RNA in situ hybridization on a tissue microarray comprising 225 cases, was associated with decreased tumor recurrence after radical prostatectomy (P=0.004), independent of pathologic tumor stage, Gleason grade, and preoperative prostate-specific antigen levels. Simultaneous assessment of hCAP-D3 and AZGP1 expression in this tumor set improved outcome prediction. We have previously demonstrated that hCAP-D3 is induced by androgen in prostate cells. Extending this finding, Gene Set Enrichment Analysis revealed enrichment of androgen-responsive genes in subtype-1 tumors (P=0.019). Our findings identify hCAP-D3 as a new biomarker for subtype-1 tumors that improves prognostication, and reveal androgen signaling as an important biologic feature of this potentially clinically favorable molecular subtype.

The results indicate that participation in MIAU leads to a decrease in stigmatization of mental illness and a greater sense of compassion among UCSF medical students. This finding is consistent with previous research suggesting social and cognitive congruence among peers and peer-teachers can result in meaningful learning experiences. MIAU may represent a sustainable model to supplement current systems to promote well-being of medical trainees.

Background Many point-of-care ultrasound devices are now “pocket-sized” or handheld, allowing easy transport during travel and facilitating use in crowded spaces or in austere low-resource settings. Concerns remain about their durability, image quality, and clinical utility in those environments. Method Five emergency physicians with training in point-of-care ultrasound employed the Butterfly iQ, a novel handheld ultrasound device, in routine clinical care in a busy, high-acuity African emergency department over a period of 10 weeks. We retrospectively evaluated the performance of the Butterfly iQ from the perspectives of both the clinicians using the device and expert ultrasound faculty reviewing the images. Results We found advantages of the Butterfly iQ in a high-acuity African emergency department include its use of a single probe for multiple functions, small size, ease of transport, relatively low cost, and good image quality in most functions. Disadvantages include large probe footprint, lower, though still adequate, cardiac imaging quality, frequent overheating, and reliance on internet-based cloud storage, but these were surmountable. We also report a wide variety of patient presentations, pathology, and procedures to which the device was used. Conclusion We conclude the Butterfly iQ is an effective, though imperfect, point-of-care ultrasound device in a low-resource emergency setting. We will continue to employ the device in clinical emergency care and teaching in this setting.
