Use of Metatarsophalangeal Joint Dorsal Subluxation in the Diagnosis of Plantar Plate Rupture.

A dorsal drawer exam, also known as a modified Lachman's test, is a common clinical test for plantar plate insufficiency. This disorder presents as a dislocated metatarsophalangeal joint. The aim of this cadaveric case study was to quantify the degree of the plantar plate pathology necessary to correlate with a positive Lachman's test.

Utility of the APACHE IV, PPI, and combined APACHE IV with PPI for predicting overall and disease-specific ICU and ACU mortality.

Background: The Acute Physiology and Chronic Health Evaluation (APACHE) IV and Palliative Performance Index (PPI) are scales commonly used to assess prognosis in intensive care units (ICUs) and acute care units (ACUs).

Objective: To compare the utility of APACHE IV, PPI, and combined APACHE IV with PPI for predicting overall and disease-specific mortality.

Design: This is a prospective cohort study using admission data during the first 24 hours.
