    Objective: To assess the effect of low-level laser therapy (LLLT) on morselized bone allograft incorporation.
    Material and Methods: Four rabbits were used as bone tissue donors. Morselized bone allografts and autografts were placed into the calvaria of 20 rabbits divided across four groups: two LLLT groups (allograft, autograft and blood clot) and two non-irradiated control groups (allograft, autograft and blood clot). Animals were euthanized at 35 days (n = 10) or 70 days (n = 10). LLLT consisted of spot laser irradiation (GaAlAs diode laser, ? = 830 nm, energy density 4 J/cm2) over four points on the skull, for a total of 16 J/cm2 per session and a total treatment dose of 128 J/cm2.
    Results: At 70 days, animals in the allograft + LLLT group had statistically significant differences in bone remodeling (p = 0.008) and vascularization (p = 0.032) as compared with the allograft control group. There were no statistically significant differences in bone incorporation in the allograft + LLLT and auto graft control groups.
    Conclusion: Light microscopy and scanning electron microscopy analysis showed a qualitatively and quantitatively positive effect of LLLT on the speed of osteogenesis after morselized bone allograft placement.

    Abstract: Hepatic Venous outflow obstruction can rarely but significantly occur following the ‘piggy back’ technique of vena caval reconstruction. There are various mechanisms that cause hepatic venous outflow obstruction. A ‘ball valve’ type of obstruction requires the liver to be elevated. This can be achieved by placing various devices under the liver. We present our experience of using the ‘Bakri tube’, a single bulb device designed for control of intra uterine bleeding, to elevate the liver and relieve hepatic venous outflow obstruction.

    Objectives/Hypothesis: To determine the utility of the new Restech pH-probe in diagnosis of laryngopharyngeal reflux by showing that patients with higher Reflux Symptom Indices and Reflux Finding Scores will have positive Restech studies.
    Study design: Retrospective study.
    Methods: The charts of all patients with suspected laryngopharyngeal reflux who presented between 1/2007 and 4/2008 to the Indiana University Clinic for Swallowing and Voice Disorders and underwent Restech evaluations were reviewed. Initial Reflux Symptom Indices and Reflux Finding Scores were recorded, as well as initial Restech findings. The association between abnormal Restech findings and elevated scores and indices were then determined, with student t-test used to determine statistical significance.
    Results: Twenty patients were included in the study. Of these, thirteen patients (65%) had positive pH events during Restech evaluation. Sixteen patients (80%) of patients had Reflex Symptom Index of 10 or greater. Eighteen patients (90%) had Reflux Finding Scores of 7 or greater. There was a trend toward a higher scores and indices in the patients (n=9) with the abnormal Restech results, but this difference did not reach significance when all patients were included. When those patients who had diffusely elevated review of systems (greater than 10 complaints) were excluded, those patients with abnormal Restech (n=6) had significantly higher scores and indices (p=0.047 and p=0.030, respectively) than those patients with normal studies (n=10).
    Conclusion: The Restech pH-probe may be a useful diagnostic tool for patients with laryngopharyngeal reflux in correlation with symptoms and examination findings.

    Abstract: Epididymal abscess, epididymo-orchitis, infected hydroceles, and testicular torsion are all rare in a neonate. The practice of exploring an acute scrotum in this patient population remains controversial. Here we describe a case of an unusual presentation of an epididymal abscess that mimics testicular torsion, in hopes of presenting the appropriate evaluation of torsion, and affirming the decision to surgically explore the acute scrotum of a neonate if suspicion remains present following appropriate work up.
