Outcome of Grade I and II Hamstring Injuries in Intercollegiate Athletes: A Novel Rehabilitation Protocol.

Background: Hamstring muscle strains represent a common and disabling athletic injury with variable recurrence rates and prolonged recovery times.

Objectives: To present the outcomes of a novel rehabilitation protocol for the treatment of proximal hamstring strains in an intercollegiate sporting population and to determine any significant differences in the rate of reinjury and time to return to sport based on patient and injury characteristics.

Study Design: Retrospective case series.

Quadriceps contusions: clinical results of immediate immobilization in 120 degrees of knee flexion.

Objective: Quadriceps contusions often result in significant time loss and the possibility of myositis ossificans. The objective of this descriptive case series was to document the results of an initial treatment regimen instituted within 10 minutes from the time of the injury.

Design: This study was a prospective case series of 47 midshipmen who sustained quadriceps contusions between August 1987 and December 2005 and who were treated identically and followed by serial examinations until the return to unrestricted full athletic activities.

Alpha-spectrins are major ubiquitinated proteins in rat hippocampal neurons and components of ubiquitinated inclusions in neurodegenerative disorders.

We have demonstrated that alpha-spectrins (alphaSpISigma* and alphaSpIISigma1) are major ubiquitinated proteins in terminally differentiated hippocampal neurons in culture. Western blotting experiments, using alphaSpISigma1, alphaSpIISigma1, and ubiquitin antibodies and lysates of 11-day-old cultured rat hippocampal neurons, have demonstrated that a single band comigrating with alphaSpISigma* and alphaSpIISigma1 in a 5% polyacrylamide sodium dodecyl sulfate gel is recognized by ubiquitin antibodies when (125)I-protein A is used for detection. Immunofluorescence staining of the 7- and 12 -day-old rat hippocampal neuron cultures using ubiquitin, alphaSpISigma1, and alphaSpIISigma1 antibodies demonstrated that all of these antibodies label neurons but not the astrocytes in the cultures.

Treatment of simple elbow dislocation using an immediate motion protocol.

The results of treatment after closed reduction of elbow dislocation vary. Twenty consecutive patients with closed posterior elbow dislocations were treated prospectively on a rapid motion, nonimmobilized functional regimen. This treatment protocol emphasizes immediate active range of motion under close supervision.

Pre- and postnatal development of the catecholamine innervation of the hypoglossal nucleus in the rat: an immunocytochemical study.

The pre- and postnatal development of the catecholamine (CA) innervation to the hypoglossal nucleus (nXII) in the rat was investigated immunocytochemically with antisera to tyrosine hydroxylase (TH). Immunoreactive profiles positive for TH were first identified in nXII on gestational day (GD) 16. By GD 18, the adult-like distribution pattern was evident, characterized by the preferential targeting of the ventromedial region of nXII, but this pattern was not consistently found in all fetuses until GD 19.
