The study aimed to investigate the effects of micro-osteoperforations (MOPs) on the mandibular bone volume/tissue volume (BV/TV) ratio changes and the rate of orthodontic tooth movement using cone-beam computed tomography images. Another objective was to evaluate the effects of MOP frequency intervals (4weeks, 8weeks, and 12weeks) on the BV/TV ratio and rate of tooth movement.

In 24 participants, 140-200g of force was applied for mandibular canine retraction. Three MOPs were made according to the scheduled intervals of the 3 different groups group 1 (MOP 4weeks), group 2 (MOP 8weeks), and group 3 (MOP 12weeks) directly at the mandibular buccal cortical bone of extracted first premolars sites. Cone-beam computed tomography scans were obtained at the 12th week after MOP application. Computed tomography Analyzer software (version 1.11.0.0; Skyscan, Kontich, Belgium) was used to compute the trabecular alveolar BV/TV ratio.

A significant difference was observed in the rate of canine movement between control and MOP. Paired t test analysis showed a significant difference (P=0.001) in the mean BV/TV ratio between control and MOP sides in all the frequency intervals groups. However, the difference was significant only in group 1 (P=0.014). A strong negative correlation (r=-0.86) was observed between the rate of canine tooth movement and the BV/TV ratio at the MOP side for group 1 and all frequency intervals together (r=-0.42).

The rate of orthodontic tooth movement can be accelerated by the MOP technique with frequently repeated MOPs throughout the treatment.

Physical examination for peritonsillar abscess (PTA) has limited sensitivity. Traditional management involves blind needle aspiration, which has a false negative rate of 10-24%. A randomized controlled trial by Costantino etal. demonstrated that point-of-care ultrasound (POCUS) improves PTA management.

Compare the use and impact of POCUS between patient cohorts prior to and after the trial by Costantino etal.

Retrospective cohort study of adult patients diagnosed with PTA. KRX-0401 clinical trial Cohort 1 presented to the emergency department (ED) January 2007-December 2008. Cohort 2 presented between January 2013 and December 2014. Data were separated into those with POCUS vs. without ultrasound (NUS). Primary endpoint was POCUS utilization. Secondary endpoints were successful aspiration, otolaryngology (ear, nose, and throat [ENT]) consultation, computed tomography (CT) imaging, unscheduled return visits, and length of stay (LOS). The Fisher's exact and t-tests analyzed data.

Cohort 1 enrolled 48 patients, vs. 114 patients for cohort 2. Twelve patients in cohort 1 had a POCUS (25%) vs 89 in cohort 2 (78%) (p<0.0001; odds ratio [OR] 0.09 (95% confidence interval [CI] 0.04-0.20). Emergency physician (EP) successful aspiration 89.1% POCUS vs. 24.5% NUS (p<0.0001; OR 25 [95% CI 10-59]). Combined EP/ENT successful aspiration 99.0% POCUS vs. 80.3% NUS (p<0.0001; OR 24 [95% CI 3-193]). ENT consultation12.9% POCUS vs. 65.6% NUS (p<0.0001; OR 0.07 [95% CI 0.03-0.17]). CT usage 23.8% POCUS vs. 37.7% NUS (p=0.07; OR 0.51 [95% CI 0.25-1.02]). Return visits 3.96% POCUS vs. 18.0% NUS (p=0.004; OR 0.18 [95% CI 0.05-0.61]).

POCUS use has increased for PTA treatment, improves aspiration, and decreases consultations, CTs, return visits, and LOS.

Trauma providers seek to accurately assess the risk of patients with abdominal seat belt sign (ASBS). As hospital costs continue to rise, identification of strategies to safely discharge emergency department (ED) patients has become crucial.

The purpose of this study is to 1) describe a large cohort of patients by type of ASBS and 2) determine the value of computed tomography (CT) of the abdomen and pelvis as a screening tool to rule out intra-abdominal injury (IAI) and support discharge of stable patients.

We conducted a retrospective case series of all patients presenting to our urban, Level I trauma center from 2013-2015. We studied motor vehicle collision patients who presented with ASBS. We further classified individuals into ASBS groups Abrasion, Ecchymosis, Abrasion+Ecchymosis, or Unknown ASBS to examine differences between groups.

In one of the largest described cohorts, the ASBS remained associated with IAI, most commonly, solid organ injury. Of 425 patients, 36.1% had some IAI on CT, but only 13.6% required laparotomy. Categorizing the type of skin injury in ASBS, we found that both abrasion and ecchymosis were associated with IAI. Initial CT performed with 100% sensitivity.

This study shows that ED trauma patients with significant seat belt abrasion or contusion can have IAI. With the very high sensitivity of modern abdominal CT scanners, clinicians could consider safe ED discharge of stable ASBS patients while providing strong return precautions. Our large cohort strengthens the evidence on decision-making in ASBS patients to ensure outcomes and use of health care resources.

Rhinoscleroma (RS) is a chronic granulomatous disease of URT caused by Klebsiella Rinoescleromatis. RS is considered endemic in Egypt. The nasal mucosa represents the primary region of occurrence. The disease can potentially spread to involve the larynx and trachea causing dysphonia, stridor, and airway obstruction.

To describe various nasal and laryngeal presentations of RS in our endemic area, to correlate between these findings and to alert physicians to suspect RS in any case of unexplained nasal or laryngeal lesion.

The study included 100 patients admitted in our otorhinolaryngolgy department (Minia University, Minia, Egypt). Patients presented with various manifestations of Rhino-pharyngo-laryngo scleroma. Diagnosis based on clinical, bacteriological, and pathological examination.

Patients had typical nasal stages of RS, however; only 12 % of patients had the typical described laryngeal presentations (ie, subglottic narrowing and subglottic membrane). Other patients presented with atypical laryngeal presentations (eg, unhealthy vocal folds, ventricular fold hypertrophy, and suproglottic sticky greenish discharge).
