Germline mutations in the succinate dehydrogenase (SDHA, SDHB, SDHC, SDHD, SDHAF2) or Von Hippel-Lindau (VHL) genes cause hereditary paraganglioma/pheochromocytoma. While SDHB (1p36) and VHL (3p25) are associated with autosomal dominant disease, SDHD (11q23) and SDHAF2 (11q13) show a remarkable parent-of-origin effect whereby tumor formation is almost completely dependent on paternal transmission of the mutant allele. Loss of the entire maternal copy of chromosome 11 occurs frequently in SDHD-linked tumors, and has been suggested to be the basis for this typical inheritance pattern...

Outer membrane protein F (OmpF) is an abundant trimeric general diffusion porin that plays a central role in the transport of antibiotics and colicins across the outer membrane of E. coli. Individual OmpF trimers in planar lipid bilayers (PLB) show one of two current-voltage asymmetries, implying that insertion occurs with either the periplasmic or the extracellular end first. A method for establishing the orientation of OmpF in PLB was developed based on the targeted covalent modification, with membrane-impermeant reagents, of peripheral cysteine residues introduced near the periplasmic or the extracellular entrance...

This study of a prospective and cross-sectional nature compared the motor and cognitive development of HIV-exposed and unexposed infants in their first 18months of age. 40 infants exposed to HIV and antiretroviral therapy (Experimental Group - EG) and 40 unexposed infants (Control Group - CG) participated in the study. They were divided into four age groups of 4, 8, 12 and 18months old, with 10 infants from EG and 10 from CG in each group. The infants were evaluated once on motor and cognitive development by the Bayley Scale of Infant and Toddler Development...

BACKGROUND: Tolerating higher partial pressures of carbon dioxide (PCO2) in mechanically ventilated extremely low birthweight infants to reduce ventilator-induced lung injury may have long-term neurodevelopmental side effects. This study analyses the results of neurodevelopmental follow-up of infants enrolled in a randomised multicentre trial. METHODS: Infants (n=359) between 400 and 1000 g birth weight and 23 0/7-28 6/7 weeks gestational age who required endotracheal intubation and mechanical ventilation within 24 hours of birth were randomly assigned to high PCO2 or to a control group with mildly elevated PCO2 targets...

The objective of this study was to evaluate the association between in utero exposure to fluoride (F) and Mental and Psychomotor Development (MDI and PDI) evaluated through the Bayley Scale of Infant Development II (BSDI-II) in infants. The sample included 65 mother-infant pairs. Environmental exposure to F was quantified in tap and bottled water samples and F in maternal urine was the biological exposure indicator; samples were collected during the 1st, 2nd and 3rd trimester of pregnancy. The mean values of F in tap water for the 1st, 2nd and 3rd trimester were 2...

Two articles in this issue of the Hastings Center Report explore two sides of the same problematic coin. In "The Limits of Surrogates' Moral Authority and Physician Professionalism," Jeffrey Berger discusses the moral problem of a surrogate refusing a treatment, palliative sedation, on behalf of a patient whose suffering is refractory to intensive palliative efforts provided by a multidisciplinary team. In "After the DNR: Surrogates Who Persist in Requesting Cardiopulmonary Resuscitation," Ellen Robinson and her colleagues analyze data from a study of cases in which physicians wished not to perform cardiopulmonary resuscitation on patients whom they thought it would harm...

We examine disparities in early child cognitive and receptive-expressive skills by ethnic ancestry among infants aged 3-24 months from Brazil and Argentina. We employ unique data on the neurodevelopment of children who were seeking routine well-child care at a set of pediatric clinics in these countries. The sample included children who had normal birth outcomes and no major health complications, allowing us to focus on variation in neurodevelopment among children without major physical health limitations. The physicians attending the pediatric clinics were trained in administering the Bayley Infant Neurodevelopmental Screener, a standardized instrument used to screen an infant's risk of neurodevelopmental problems on various domains of abilities...

OBJECTIVE: Few data about the development of infants born to women with bipolar disorder have been published. We hypothesized that infants of women with bipolar disorder (by DSM-IV criteria) treated with psychotropics (BD+) or untreated with psychotropics (BD-) would demonstrate poorer cognitive and behavioral development than infants of controls. On the basis of previous studies, we expected that psychotropic-exposed infants of women in the BD+ group would have poorer neuromotor performance during infancy...

Deregulated extracellular signal-regulated kinase (ERK) signaling drives cancer growth. Normally, ERK activity is self-limiting by the rapid inactivation of upstream kinases and delayed induction of dual-specificity MAP kinase phosphatases (MKPs/DUSPs). However, interactions between these feedback mechanisms are unclear. Here we show that, although the MKP DUSP5 both inactivates and anchors ERK in the nucleus, it paradoxically increases and prolongs cytoplasmic ERK activity. The latter effect is caused, at least in part, by the relief of ERK-mediated RAF inhibition...

INTRODUCTION: Patients with primary melanoma of the scalp have been reported to have worse disease-related outcomes compared with other anatomical regions. There are few studies in the literature specifically addressing recurrence patterns and treatment outcomes for primary scalp melanoma as a discrete anatomical sub-region. We sought to identify key features adversely influencing disease control and survival and to clarify the role of resection plane, margin, and method of reconstruction in the management of this disease process...

Importance: Advances in surgical techniques, the advent of intensity-modulated radiotherapy (IMRT), and the use of concurrent chemotherapy in oral squamous cell carcinoma (OSCC) have led to improvement of locoregional control (LRC), but not distant control (DC). Moreover, the development of distant metastases (DM) in OSCC has a dismal prognosis. Objective: To determine the characteristics and risk factors of DM following postoperative IMRT in OSCC, and to identify the clinicopathological features that could be associated with distant-only failure (DOF)...

Phelan-McDermid syndrome is a rare genetic disorder caused by the terminal or interstitial deletion of the chromosome 22q13.3. Patients with this syndrome usually have global developmental delay, hypotonia, and speech delays. Several putative genes such as the SHANK3, RAB, RABL2B, and IB2 are responsible for the neurological features. This study describes the clinical features and outcomes of Korean patients with Phelan-McDermid syndrome. Two patients showing global developmental delay, hypotonia, and speech delay were diagnosed with Phelan-McDermid syndrome via chromosome analysis, fluorescent in situ hybridization, and multiplex ligation-dependent probe amplification analysis...

There has been a considerable drive to encourage a wide range of professional groups to incorporate alcohol screening (or identification) and brief advice (IBA) into their everyday practice. This article aims to examine the role of training in promoting IBA delivery in contexts outside primary care and other health settings. The data are drawn mainly from a structured online survey supplemented by illustrative material from nine qualitative interviews and insights from an expert workshop. Findings support the results from other research that issues relating to role relevance and role security continue to act as barriers to professional change...

Deformational plagiocephaly (DP) in infants has been associated with developmental delay that can last until adolescence. Despite this association and a 5-fold increase in incidence of DP over the past 2 decades, there are currently no guidelines regarding screening for developmental delay or identification of which infants with DP are at the greatest risk of delay. A prospective, nonrandomized study was performed. Infants diagnosed with DP who had no prior intervention were eligible for enrollment. Cranial deformity was measured by cross-cranial measurements using calipers, and developmental delay was measured using the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III)...
