Can Isolated Discordant Atrioventricular Connections Survive Without Interatrial or Interventricular Shunt?

Clinical presentation of isolated discordant atrioventricular connections is akin to transposition of the great arteries. In the absence of a significant intracardiac shunt, profound cyanosis is expected at birth. We report one such 5-month-old infant who had only mild cyanosis.

Large aortopulmonary collateral artery exclusively supplying the lower lobe of left lung in an infant with common arterial trunk with aortic dominance with confluent pulmonary arteries.

Introduction: Common arterial trunk with aortic dominance has well-developed bilateral pulmonary arterial arborization without any essential major aortopulmonary collateral arteries (MAPCAs), whereas "solitary" arterial trunk is characterized by collateral arterial supply to all bronchopulmonary segments and absent pulmonary arteries.

Case Report: We report a term female neonate with common arterial trunk with aortic dominance with confluent pulmonary arteries with a large MAPCA as the sole blood supply to the lower lobe of the left lung.

Results: Initial diagnostic workup missed this MAPCA from the descending thoracic aorta.

Echo Rounds: Partial Anomalous Systemic and Pulmonary Venous Return.

Anomalous drainage of a right-sided superior vena cava to the left atrium is a rare variant of systemic venous return anomalies. During the course of investigation for a heart murmur, an asymptomatic child was found to have a superior sinus venosus atrial septal defect with partial anomalous systemic and pulmonary venous drainage. Despite the right superior vena cava overriding the upper end of the atrial septum and draining into the left atrium, the child did not exhibit hypoxemia.

Childhood Obesity.

Childhood obesity is a pathologic process with multifactorial causes. The reasons range widely. Obesity leads to chronic health conditions, increasing morbidity.

Percutaneous Closure of Ventricular Septal Defects in 116 Patients: Experience with different devices.

Objectives: This study aimed to review the experience with percutaneous closure of ventricular septal defects (VSDs) at the National Heart Center (NHC) in Muscat, Oman.

Methods: This retrospective study was conducted from November 2008 to December 2017. Patients' electronic medical records were reviewed to identify their clinical, imaging and interventional data before and after the procedure and on the last follow-up.

Double outlet right atrium-A "bridge" across the bridging leaflets.

Introduction: Mal-alignment between the inter-atrial septum (IAS) and the inter-ventricular septum (IVS) during cardiac embryogenesis results in abnormal atrioventricular (AV) connections ranging from doubleoulet left atrium (DOLA) to double outlet right atrium (DORA)1.

Case Report: We report DORA resulting from partial override of the interatrial septum (IAS) across the cleft between the bridging leaflets of the left atrioventricular (AV) valve.

Results: Successful surgical management with preservation of the orifice is described, leading to an unusual type of double orifice left AV valve.

Mixed Methods Study of Patient and Primary Care Provider Perceptions of Chronic Pain Treatment.

Objective: A mixed-method study involving patient focus groups and survey of primary care providers (PCPs) sought to compare perspectives about chronic pain (CP) and its treatment. Our goal was to identify needs and barriers for facilitating patient-centered care.

Methods: Two focus groups of CP patients from a single academic medical center explored interactions with PCPs and their understandings, experiences, and expectations of CP treatment.

Eosinophilic Granuloma of the Mandible.

Eosinophilic granuloma (EG) is a rare histiocytic disorder resulting from clonal proliferation of Langerhans cells. Eosinophilic granuloma, the most benign of the three entities of Langerhans cell histiocytosis, may be multiple or solitary. This lesion can affect any bones but commonly involves the mandible when the jaws are affected.

Comparative Evaluation of Hydrophobic and Hydrophilic Resin-based Sealants: A Clinical Study.

Aim: The purpose of this study is to clinically evaluate and compare the retention and evidence of caries of three fissure sealants.

Materials And Methods: A total of 150 children, between 7 and 13 years of age, with fully erupted permanent molars, had sealants placed using a full-mouth design. Sealant retention was evaluated at 1, 3, 6, 9, and 12 months later.

Correlation Between Body Mass Index and Dental Caries Among Three- to 12-Year-Old Schoolchildren in India: A Cross-Sectional Study.

Introduction:  Diet is a deeply ingrained element of a person's life. Children's dietary habits are a significant contributor to obesity and dental caries. Dental caries during childhood continues to be a significant public health concern, while childhood obesity is increasingly being cited as a major public health problem.

Efonidipine-Induced Exanthematic Drug Eruption and Literature Review.

We report the case of an elderly woman who developed exanthematic drug eruption after administration of efonidipine. An 84-year-old woman presented to emergency department with complaints of generalized itching and erythema since 4 days. She was on human-soluble insulin since 11 years.

Intraosseous lipoma of the maxillary tuberosity: A rare entity with diagnostic challenge.

Lipoma is called the "universal tumor" or the "ubiquitous tumor" as it occurs anywhere in the body where fat is found. Intraosseous lipoma is a rare lesion that constitutes not more than 0.1% of bone tumors.

Volumetric analysis of hand, reciprocating and rotary instrumentation techniques in primary molars using spiral computed tomography: An comparative study.

Objective: This present study was conducted to analyze the volumetric change in the root canal space and instrumentation time between hand files, hand files in reciprocating motion, and three rotary files in primary molars.

Materials And Methods: One hundred primary mandibular molars were randomly allotted to one of the five groups. Instrumentation was done using Group I; nickel-titanium (Ni-Ti) hand file, Group II; Ni-Ti hand files in reciprocating motion, Group III; Race rotary files, Group IV; prodesign pediatric rotary files, and Group V; ProTaper rotary files.

An Uncommon Side Effect of a Commonly Used Antibiotic: Amoxicillin-Clavulanic Acid Induced Hepatitis.

Amoxicillin-Clavulanic acid continues to be one of the most commonly used antibiotic combinations. Hepatic injury due to this antibiotic is rare. We report a case of amoxicillin-clavulanic acid induced hepatitis causing painless jaundice to bring to attention this rare side effect of this commonly used antibiotic.

Induced Pectus Carinatum.

During the surgical repair of a truncus arteriosus with aortic arch interruption and pulmonary artery origin stenosis, a Contegra conduit was implanted as part of reconstruction of the pulmonary artery in a small infant. There was a mismatch between the conduit size and the patient that resulted in protrusion of the conduit between the sternal edges. To accommodate the conduit inside the thoracic cavity, traction was applied to the sternum that was gradually released over a period of time guided by transesophageal echocardiography-derived cardiac output data, as well as continuous hemodynamic parameters.

Computed Tomographic Evaluation of K3 Rotary and Stainless Steel K File Instrumentation in Primary Teeth.

Introduction: The intention of root canal preparation is to reduce infected content and create a root canal shape allowing for a well condensed root filling. Therefore, it is not necessary to remove excessive dentine for successful root canal preparation and concern must be taken not to over instrument as perforations can occur in the thin dentinal walls of primary molars.

Aim: This study was done to evaluate the time preparation, the risk of lateral perforation and dentine removal of the stainless steel K file and K3 rotary instrumentation in primary teeth.
