Fast micrographia: An unusual but distinctive sign

An unusual "empty delta sign".

A 34 year old man developed fever, right ear pain, and diffuse pulsatile headache 10 days prior to admission. Five days later he noticed difficulty in walking, instability, and intention tremor. Neurological examination showed a wide base gait, stance instability, slurred speech, bilateral horizontal nystagmus, intention tremor, four limb dysmetria, and dysdiadochokinesia. There were no signs o...

To devote to Micrographia a standard review would be similar to an argument as to ...

The dromedary sign--an unusual capnograph tracing.

ABNORMAL capnographs are not unusual in clinical anesthesia. These typically result from uneven ventilation in patients with lung disease. Previous reports also have noted abnormal capnograph tracings resulting from loose connections between the end-tidal carbon dioxide sample line and the gas analyzer or other leaks in the system. The resulting biphasic waveform has been described as a long lo...

"Sentinel lines"--an unusual sign of lower lobe contraction.

Of the various densities occurring in the lower zones of the standard postero-anterior chest radiograph, one sign has been ignored. Coarse linear densities at the bases may be due to adjacent lower lobe contraction. The cause is related to bending or kinking of the lower zone bronchi, usually the superior and inferior branches of the lingular bronchi. The densities are probably due to mucus-fil...
