AI Article Synopsis
- PJRT is a rare congenital arrhythmia mainly found in infants and children, often leading to dilated cardiomyopathy (DCM) during pregnancy.
- Some infants may show a normal heart rate, making diagnosis difficult.
- In one case, a neonate diagnosed with DCM prenatally had PJRT confirmed after birth, and treatment with digoxin and amiodarone successfully restored normal heart function by 16 months.
Article Abstract
Permanent junctional reciprocating tachycardia (PJRT) is a rare form of congenital arrhythmia occurring predominantly in infants and children. Prenatal presentation is frequently characterized by incessant tachycardia leading to dilated cardiomyopathy (DCM). Some patients can have a normal heart rate which leads to a delayed diagnosis. We report a case of a neonate who was presented prenatally with DCM, fetal hydrops, and no signs of fetal arrhythmia. Diagnosis of PJRT was established after delivery with characteristic electrocardiographic patterns. Successful conversion to sinus rhythm with digoxin and amiodarone was achieved three months later. At 16 months of age, both echocardiography and electrocardiography were normal.

Relative contributions of genetic and environmental factors to palatal morphology: a longitudinal twin study.

Article Synopsis
- The study investigated how genetics and environment affect changes in palatal (roof of the mouth) shape during tooth development.
- Using 3D digital models of dental casts from 228 twin pairs, researchers measured different dimensions of the palate at various dental stages and analyzed the data with genetic modeling techniques.
- Results showed that while most palatal dimensions increased over time, genetic factors played a significant role, especially in the posterior region, and non-shared environmental factors were also important throughout development.
Vestibular epilepsy: clinical and electroencephalographic characteristics with the proposed diagnostic criteria.

Background: Focal seizures may encompass vestibular sensations in their symptomatology. When these manifestations occur in isolation or constitute the predominant symptom, they prompt consideration for diagnosing recurrent paroxysmal vertigo. However, the characterization of "vestibular epilepsy" remains debated and underexplored.

BACKGROUND Cardiac tumors are divided into 2 categories: primary, originating from the heart, and metastatic, which spread to the heart from a different location, with metastatic tumors representing the vast majority. Cardiac tumors, depending on the size and location, can predispose patients to arrhythmic or hemodynamic complications. We present a patient with a history of B-cell lymphoma (DLBCL) in remission for 3 years who developed acute onset congestive heart failure and complete heart block secondary to DLBCL invasion of the myocardium.

Isolated abducens nerve palsy (IANP), caused by secondary communicating hydrocephalus, has been rarely documented; in addition, its mechanism and appropriate treatment are not understood well. This study presents a case of bilateral IANP with hydrocephalus in a 62-year-old man who was successfully treated with cerebrospinal fluid (CSF) diversion to correct an enlarged retroclival space during the follow-up of recurrent brain tumor in the right parieto-occipital lobe. The patient was treated with three resections, temozolomide, and irradiation before developing IANP.

Despite offering several potential benefits over standard prosthetic aortic valve replacement, the use of the pulmonary autograft has been limited to date due to concerns over the risk of pulmonary autograft expansion and the need for reintervention. Several techniques using materials with biomimetic potential have been developed to reduce this complication. The incidence, risk factors, and pathophysiology of pulmonary autograft dilatation are discussed in this article.
