Orthodontic Management of a Growing Patient With a Skeletal Class III Malocclusion and an Anterior Open Bite: A Case Report.

Class III malocclusion presents many challenges due to its varying elements of imbalance in skeletal, dental, and soft tissues. This necessitates a comprehensive treatment plan, including growth modification during the pre-pubertal growth phase, and long-term retention to reduce the chances of orthognathic surgery later. The components of Class III malocclusion include maxillary retrognathism, mandibular prognathism, or, in some cases, a combination of both.

Delaying Intraoral Radiographs during the COVID-19 Pandemic: A Conundrum.

Background: The COVID-19 pandemic has made dentists very assiduous about cross-infection during dental treatment, thereby delaying dental radiographs for treatment. However, patients needing dental emergency treatment in the ongoing pandemic require relevant intra/extraoral dental radiography for adequate diagnosis and treatment planning.

Methods: This article is aimed at adding to the hot debate: Is delay for intraoral radiographs justified or a possible proxy? As a narrative review, it provides an insight into the reasons for delaying intra-oral dental radiographs during in the pandemic and options of the nontraditional radiographic techniques available until the pandemic subsides.

Comparing bite force in untreated and orthodontically treated non- extraction cases with MBT appliance and self ligation technique using T-scan.

Aim: Aim of this cross sectional study was to compare the bite force and the individual tooth load among three groups of patients: cases finished with the Self ligation appliance (Damon-Q®, 0.022"X0.028" prescription) cases finished with the MBT (McLaughlin, Bennett and Trevisi) appliance system (0.

Mortality Prediction Using SaO/FiO Ratio Based on eICU Database Analysis.

Purpose: PaO to FiO ratio (P/F) is used to assess the degree of hypoxemia adjusted for oxygen requirements. The Berlin definition of Acute Respiratory Distress Syndrome (ARDS) includes P/F as a diagnostic criterion. P/F is invasive and cost-prohibitive for resource-limited settings.

Effect of Craniofacial Morphology on Pharyngeal Airway Volume Measured Using Cone-Beam Computed Tomography (CBCT)-A Retrospective Pilot Study.

Background: The present study aimed to determine the correlation between pharyngeal airway volume and craniofacial morphology through cone-beam computed tomography (CBCT). Additionally, the study analyzed the influence of gender on pharyngeal airway volume. (2) Methods: 80 CBCT scans of 40 male and 40 female patients (mean age: 15.

In vitro selected GUAA tetraloop-binding receptors with structural plasticity and evolvability towards natural RNA structural modules.

GNRA tetraloop-binding receptor interactions are key components in the macromolecular assembly of a variety of functional RNAs. In nature, there is an apparent bias for GAAA/11nt receptor and GYRA/helix interactions, with the former interaction being thermodynamically more stable than the latter. While past in vitro selections allowed isolation of novel GGAA and GUGA receptors, we report herein an in vitro selection that revealed several novel classes of specific GUAA receptors with binding affinities comparable to those from natural GAAA/11nt interactions.

Dentistry during and after COVID-19 Pandemic: Pediatric Considerations.

Unlabelled: This article is a rumination on the outbreak of the dreaded coronavirus disease-2019 (COVID-19) pandemic which has engulfed both the developed and the developing countries, thereby causing widespread global public health concerns and threats to human lives. Although countries have made varied efforts, the pestilence is escalating due to the high infectivity. It is highly likely that dental professionals in upcoming days will come across COVID-19 patients and SARS-CoV-2 carriers, and hence must ensure a tactful handling of such patients to prevent its nosocomial spread.

Appropriate orthodontic appliances during the COVID-19 pandemic: A scoping review.

Introduction: The esoteric Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection or COVID-19 has been an unusual plummet in dental/orthodontic practice. Based on current recommendations for various amendments in an orthodontic practice, this scoping review aims to identify orthodontic appliances that are most appropriate to us during this on-going pandemic.

Methods: Electronic databases (PubMed, Scopus, Web of Science, Science Direct, and Google Scholar) were searched up until August 11, 2020.

Cytokine levels in gingival crevicular fluid samples of patients wearing clear aligners.

Objective: The aim of this study was to assess & compare the changes in cytokine levels in GCF samples of patients wearing clear aligners.

Methods: GCF samples of 10 patients undergoing orthodontic treatment, for correction of lower anterior crowding with clear aligners, were collected on day 0, 1, 3, 7 and 21 using periopaper strips. The upper arch was taken as the control site.

Pressure Regulated Volume Control (PRVC): Set it and forget it?

Pressure-regulated volume control (PRVC) is a mode of ventilation in which the ventilator attempts to achieve set tidal volume at lowest possible airway pressure. This mode of ventilation is being commonly used as the initial mode of ventilation in many intensive care units. We describe two cases where this adaptive mode of ventilation became maladaptive leading to patient-ventilator dyssynchrony.

Comparative Assessment of Clinical and Predicted Treatment Outcomes of Clear Aligner Treatment: An in Vivo Study.

Objective: The objective of this clinical study was to assess the predicted software models and clinical models and to compare the stage models of both the groups so as to evaluate the efficacy of tooth movement with clear aligner.

Methods: The sample size included 10 cases with mild anterior crowding treated with aligner therapy. The predicted software models were superimposed on the clinical stereolithography (STL) models at various stages by using the MeshLab software.

Common Cognitive Biases in Nephrology Critical Care: A Plea for Metacognition.

The intensive care unit (ICU) is an incredibly complex environment, and ICU rounds are mentally taxing. The cognitive biases that tend to arise in mentally taxing environments such as the ICU pose a risk to patients. This review discusses 10 common cognitive biases and logical fallacies using examples in Nephrology Critical Care.

The Use of Portal Vein Pulsatility to Differentiate Hypervolemic and Hypovolemic Hyponatremia.

Hypotonic hyponatremia is a common electrolyte disorder defined by a blood serum sodium value of less than 136 meq/L. A challenge in managing hyponatremia is accurately determining the etiology for the free water excess as management can markedly differ. Accurate diagnosis of the etiology of hypotonic hyponatremia requires precision in the determination of extracellular volume status.

Retrospective analysis of inferior vena cava collapsibility with point of care ultrasound and urine sodium and FENa in patients with early stage acute kidney injury.

Early stage acute kidney injury (AKI) is an independent risk factor for an increase in mortality. Accurate assessment of volume status is a major challenge during the early stages of acute renal injury. Determining volume status based on the history and physical exam lacks accuracy.

Pneumatosis of the esophagus and intestines with portal venous air: a rare presentation.

Pneumatosis intestinalis is a radiographic finding that represents a spectrum of conditions ranging from benign disease to abdominal sepsis and death. Along with portal venous gas, it is generally considered an ominous sign prompting emergency operative intervention. We report a rare case showing that nonoperative therapy can be considered in a seriously ill patient with esophageal, gastric and portal venous air.

Splenic infarct in a patient with Infectious Mononucleosis: a rare presentation.

We report a case of a 25-year-old obese, currently smoking, female diagnosed with EBV infectious mononucleosis. The patient complained of sudden onset abdominal pain with progressively increasing intensity in the left upper quadrant. Abdominal CT scan showed a wedge infarct of the spleen.

Multi-organ failure, weeks after being exposed to murky water - rule out leptospirosis.

Leptospirosis is a rare zoonotic disease which occurs in people exposed to contaminated water or/and animal urine. We report two cases of moderate to severe leptospirosis. The first case was a healthy middle-aged biology professor who recently visited his family in Jamaica and presented with multi-organ failure.

Point-of-care ultrasonography as a training milestone for internal medicine residents: the time is now.

Point-of-care (POC) ultrasonography is considered fundamental in emergency medicine training and recently has become a milestone in critical care fellowship programs as well. Currently, there is no such standard requirement for internal medicine residency programs in the United States. We present a new case and briefly review another case at our institution - a community hospital - in which internal medicine house staff trained in ultrasonography were able to uncover unexpected and critical diagnoses that significantly changed patient care and outcomes.

Over-diuresis or cardiac tamponade? An unusual case of acute kidney injury and early closure.

An 84-year-old man with hypertension and a history of deep venous thrombosis (on warfarin) was admitted with shortness of breath presumed to be due to congestive heart failure. Echocardiogram performed the following day showed a low-normal ejection fraction with signs of elevated right-sided pressures but was otherwise normal. He improved with diuretic therapy but after a few days was found to be hypotensive with a concomitant rise in creatinine with decreased urine output.

An Erupted Dilated Odontoma: A Rare Presentation.

A dilated odontoma is an extremely rare developmental anomaly represented as a dilatation of the crown and root as a consequence of a deep, enamel-lined invagination and is considered a severe variant of dens invaginatus. An oval shape of the tooth lacking morphological characteristics of a crown or root implies that the invagination happened in the initial stages of morphodifferentiation. Spontaneous eruption of an odontoma is a rare occurrence and the occurrence of a dilated odontoma in a supernumerary tooth is even rarer with only a few case reports documented in the English literature.

Hereditary angioedema presenting as irritable bowel syndrome: a case of early closure.

Abdominal pain is one of the most common reasons for outpatient and emergency department visits. We present one such case of early closure in a 32-year-old male with recurrent abdominal pain who was diagnosed with irritable bowel syndrome (IBS). Family history was suspicious for hereditary angioedema (HAE).
