OBJECTIVE: Our objective was to determine specialist physicians' attitudes and practices regarding disclosure of pre-referral errors. SUMMARY BACKGROUND DATA: Physicians are encouraged to disclose their own errors to patients. However, no clear professional norms exist regarding disclosure when physicians discover errors in diagnosis or treatment that occurred at other institutions before referral. METHODS: We conducted semistructured interviews of cancer specialists from 2 National Cancer Institute-designated Cancer Centers...

Celiprolol is a β-blocker with a unique pharmacologic profile: it is a β1-andrenoceptor antagonist with partial β2 agonist activity. Given this combination of effects, celiprolol may be better described as a elective adrenoreceptor modulator. It has antihypertensive and antianginal properties and is indicated for those uses in various countries around the world. In the United States, however, the proposed indication for this drug will be for the treatment of vascular type Ehlers-Danlos syndrome, a rare connective tissue isorder haracterized by fragile arterial structure and an increased risk of life-threatening vascular complications...

The aim of the present study was to establish an in vitro Kleefstra syndrome (KS) disease model using the human induced pluripotent stem cell (hiPSC) technology. Previously, an autism spectrum disorder (ASD) patient with Kleefstra syndrome (KS-ASD) carrying a deleterious premature termination codon mutation in the EHMT1 gene was identified. Patient specific hiPSCs generated from peripheral blood mononuclear cells of the KS-ASD patient were differentiated into post-mitotic cortical neurons. Lower levels of EHMT1 mRNA as well as protein expression were confirmed in these cells...

Hypothalamic hypocretin (orexin) peptides mediate arousal, attention, and reward processing. Fibers containing orexins project to brain structures that govern motivated behavior, including the ventral tegmental area (VTA). A number of psychiatric conditions, including attention deficit hyperactivity disorder (ADHD) and substance use disorders, are characterized by deficits in impulse control, however the relationship between orexin and impulsive behavior is incompletely characterized. The effects of systemic or centrally administered orexin receptor (OXR) antagonists on measures of impulsive-like behavior in rats were evaluated using the five-choice serial reaction time task (5-CSRTT) and delay discounting procedures...

BACKGROUND: Regulation of calcium is mediated by parathyroid hormone (PTH) and 1.25-dihydroxyvitamine D3. The calcium-sensing receptor (CaSR) regulates PTH release by a negative feedback system. Gain-of-function mutations in the CaSR gene reset the calcium-PTH axis, leading to hypocalcaemia. PATIENTS AND METHODS: We analysed a family with hypocalcaemia. The proband was a 47-year-old man (index, patient I1), who presented with paraesthesias in both limbs. He has two sons (patient II1 a nd I I2)...

The management of pediatric airway pathology can be challenging and requires a dedicated team, consisting of thoracic surgeons, phoniatricians, logopedics, pediatricians and anesthetists. It necessitates a tailored treatment approach for each individual patient in order to address the minor variances that exist between cases. The majority of pediatric airway problems are a sequela of prematurity and prolonged post-partal intubation/tracheostomy. Surgical repair is often complicated by additional malformation or severe comorbidities...

Intrauterine growth restriction (IUGR) is when fetuses and newborn infants have not reached their true growth potential as genetically defined. Fetuses with IUGR develop in a less than ideal environment that leads to epigenetic changes and marks infants' metabolism for the rest of their lives. Epigenetic changes affect insulin-like growth factor-1 (IGF-1) levels and lead to insulin resistance and ultimately to a metabolic syndrome. The metabolic syndrome is a constellation of illnesses that raise one's risk for type 2 diabetes mellitus, coronary artery disease, and ischemic heart disease, including hypertension, dyslipidemia, central obesity, insulin resistance, and inflammation...

The management of craniosynostosis, especially in the setting of craniofacial syndromes, is ideally done in a multidisciplinary clinic with a team focused toward comprehensive care. Craniosynostosis is a congenital disorder of the cranium, caused by the premature fusion of one or more cranial sutures. This fusion results in abnormal cranial growth due to the inability of the involved sutures to accommodate the growing brain. Skull growth occurs only at the patent sutures, resulting in an abnormal head shape...

Four different cruciform sample designs, based on the work of Abu-Farha et al., were studied in this paper. Key features of this design are a recessed pocket with fillet and re-entrant corners. These samples were shown via digital image correlation to achieve widely differing strain values inside and outside the pocket. From the results of these tests, there are two competing failure mechanisms in the sample. The pocket region is affected by stress concentrations caused by the fillet, and re-entrant notches lead to strain limited constraints similar to diffuse and localized necks in uniaxial samples...

Pathological angiogenesis in the eye is an important feature in the pathophysiology of many vision-threatening diseases, including retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration, as well as corneal diseases with abnormal angiogenesis. Development of reproducible and reliable animal models of ocular angiogenesis has advanced our understanding of both the normal development and the pathobiology of ocular neovascularization. These models have also proven to be valuable experimental tools with which to easily evaluate potential antiangiogenic therapies beyond eye research...

REVIEW
Janis M Dionne, Joseph T Flynn
Blood pressure is considered a vital sign, as values too low or too high can be related with serious morbidity and mortality. In neonates, normal blood pressure values undergo rapid changes, especially in premature infants, making the recognition of abnormal blood pressures more challenging. Severe hypertension can occur in neonates and infants and is a medical emergency, often manifesting with congestive heart failure or other life-threatening complications. The cause or risk factors for the hypertension can usually be identified and may guide management...

This report describes a paediatric patient presenting with haemodynamically stable non-sustained ventricular tachycardia 1 day after minor blunt chest trauma. Initial laboratory studies, chest X-ray and echocardiography were normal; however, cardiac MRI revealed precordial haematoma, myocardial contusion and small pericardial effusion. Throughout her hospital course, she remained asymptomatic aside from frequent couplets and triplets of premature ventricular contractions. Ectopy was controlled with oral verapamil...

Inhibition of amyloid fibril formation by a lens protein namely human γD-crystallin (HGD) under stressful conditions was targeted by using some small molecules like direct red 80 (DR), orange G (OG) and rhodamine B (RH). The protein itself was found to form matured fibrils after 48hours of incubation at pH 3.0 at 37°C. Various fluorescence based assays (thioflavinT assay, ANS binding assay, intrinsic Trp fluorescence determination), circular dichroism and microscopic imaging techniques were used in the inhibition studies...

Hearing loss is the most common form of sensory impairment in humans, affecting 5.3% worldwide population. In industrial countries, age-related hearing loss is a major health problem affecting one-third of individuals over 65years old. However, the physiological and molecular changes involved in this senescence process remain unclear. In this study, we determined the influence of age on auditory brainstem response (ABR) and the distortion product otoacoustic emissions (DPOAE) in the premature senescence mouse model SAMP8 for five months...
