Point-of-Care Ultrasound for the Assessment of Digital Clubbing

  Digital clubbing, a resultant finding from the proliferation of connective tissue in the terminal portion of fingers or toes, has long been recognized as a sign for a number of underlying infectious, inflammatory, malignant, and vascular conditions.1 A profile angle >176° and a hyponychial angle >192° support the diagnosis of clubbing.1Quantification of these angles can […]

The lower panel demonstrates the lesion in the supraclavicular area on conventional ultrasonography. Encapsulated cystic lesion with hyperechogenic areas inside being in constant movement. The upper panel shows largely decreased elasticity of the peripheral part of the lesion on sonoelastographic examination.

Subcutaneous Lesion in an Oncologic Patient

A 40-year-old Caucasian woman presented to our university hospital after she noticed a mass in the right supraclavicular area. The lump was easily palpable, sized 1-1.5 cm, firm, and rather immovable, with surrounding edema (Figure 1). She had noticed the lesion approximately 2 weeks earlier, and during that time the mass was gradually enlarging. Her personal […]

Primary Care Management of Skin Abscesses Guided by Ultrasound

Primary care providers often manage skin abscesses in the outpatient setting. Estimating the size and depth of an abscess, and distinguishing abscess from cellulitis by clinical examination can be challenging due to surrounding firm tissue induration. Definitive treatment of abscess requires incision and drainage, and the approach chosen may be altered by abscess size, depth, […]

Should a Hand-carried Ultrasound Machine Become Standard Equipment for Every Internist?

It has been many decades since any new piece of equipment found its way into the internist’s black bag. The stethoscope, neurologic hammer, otoscope, and ophthalmoscope have been there for approximately 200 years. Recently, however, there has been a flurry of investigative work involving a new diagnostic tool with considerable potential for everyday use in […]

Hand-carried Ultrasound Performed by Hospitalists: Does It Improve the Cardiac Physical Examination?

Adding hand-carried ultrasound information to the physician’s physical examination increases the accuracy of hospitalists’ assessment of left ventricular dysfunction, cardiomegaly, and pericardial effusion, but fails to improve assessment of valvular heart disease. Abstract Objective The traditional physical examination of the heart is relatively inaccurate. There is little information regarding whether cardiac hand-carried ultrasound performed by […]
