Irreversible Respiratory Failure in a Full-Term Infant with Features of Pulmonary Interstitial Glycogenosis as Well as Bronchopulmonary Dysplasia. - AJP reports
Pulmonary interstitial glycogenosis (PIG) is a rare interstitial lung disease in the newborns. We report on the clinical presentation and pathological findings of a full-term male infant with pulmonary hypertension requiring extracorporeal membrane oxygenation (ECMO). An open lung biopsy demonstrated interstitial changes resembling pulmonary interstitial glycogenosis as well as bronchopulmonary dysplasia (BPD), without convincing evidence of maturational arrest, infection, alveolar proteinosis, or alveolar capillary dysplasia. The boy was treated with glucocorticoids and, after a few days, was weaned from ECMO. A few hours later, the patient died due to acute severe pulmonary hypertension with acute right ventricular failure. The etiology and underlying pathogenic mechanisms of PIG are unknown. The clinical outcomes are quite varied. Deaths have been reported when PIG exists with abnormal lung development and pulmonary vascular growth and congenital heart disease. No mortality has been reported in PIG together with BPD in full-term infants. In this article, we reported on a full-term infant with interstitial changes resembling PIG and BPD who expired despite no convincing evidence of an anatomical maturational arrest or congenital heart disease.
Rare variants in the neurotrophin signaling pathway implicated in schizophrenia risk. - Schizophrenia research
Multiple lines of evidence corroborate impaired signaling pathways as relevant to the underpinnings of schizophrenia. There has been an interest in neurotrophins, since they are crucial mediators of neurodevelopment and in synaptic connectivity in the adult brain. Neurotrophins and their receptors demonstrate aberrant expression patterns in cortical areas for schizophrenia cases in comparison to control subjects. There is little known about the contribution of neurotrophin genes in psychiatric disorders. To begin to address this issue, we conducted high-coverage targeted exome capture in a subset of neurotrophin genes in 48 comprehensively characterized cases with schizophrenia-related psychosis. We herein report rare missense polymorphisms and novel missense mutations in neurotrophin receptor signaling pathway genes. Furthermore, we observed that several genes have a higher propensity to harbor missense coding variants than others. Based on this initial analysis we suggest that rare variants and missense mutations in neurotrophin genes might represent genetic contributions involved across psychiatric disorders.Copyright Â© 2015 Elsevier B.V.

Effectiveness of high fidelity video-assisted real-time simulation: a comparison of three training methods for acute pediatric emergencies. - International journal of pediatrics
Background. Video-assisted real-time simulation (VARS) offers the possibility of developing competence in acute medicine in a realistic and safe environment. We investigated the effectiveness of the VARS model and compared it with educational methods like Problem-Based Learning (PBL) and Pediatric Advanced Life Support (PALS). Methods. 45 fourth-year medical students were randomized for three educational methods. Level of knowledge and self-efficacy were measured before and after intervention. Clinical performance was measured by a blinded observer using a video checklist of prescripted scenarios on a high-fidelity simulator. Results. Knowledge test and self-efficacy scores improved significantly (P < 0.001) without differences between educational groups. The VARS group showed significantly (P < 0.05) higher scores on both postintervention scenarios concerning structure and time. Conclusion. VARS training is an effective educational method teaching pediatric acute care skills in the undergraduate curriculum. When compared to PBL and PALS training, VARS training appears to be superior in enhancing short-term clinical performance.
Solitary fibrous tumour of the infratemporal fossa. - The Journal of laryngology and otology
Solitary fibrous tumour was first described as a pleural tumour. It has been reported in a number of extrapleural sites including the head and neck. We present the first case of solitary fibrous tumour of the infratemporal fossa described in the English literature. Complete excision was achieved using the orbitozygomatic infratemporal craniotomy approach.
Solitary infantile myofibromatosis of axis. A case report. - Spine
Lytic lesions of the cervical spine are rare and may be caused by infection or tumors. The authors report a rare case of solitary infantile myofibromatosis presenting as a lytic lesion of the second cervical vertebral body (C2) and odontoid, causing atlanto-axial instability.
