PCBs and dioxins/furans in attic dust collected near former PCB production and secondary copper facilities in Sauget, IL

AbstractSamples of settled attic dust from fourteen buildings located within two miles of the Solutia W.G. Krummrich and Cerro Flow Products facilities in Sauget, Illinois were analyzed for PCBs and dioxins/furans using HRGC/HRMS. The facilities released vast quantities of PCBs and dioxins/furans into the environment over many decades. The concentrations and homologues present in the samples of attic dust and in samples of soil collected by U.S. EPA demonstrate atmospheric transport of PCBs and dioxins/furans from these manufacturing sites and local dumps contaminated with these pollutants. The results demonstrate that attic dust is a useful metric for assessing historical exposure to atmospheric emissions

Treating childhood intermittent distance exotropia: a qualitative study of decision making

BACKGROUND: Engaging patients (parents/families) in treatment decisions is increasingly recognised as important and beneficial. Yet where the evidence base for treatment options is limited, as with intermittent distance exotropia (X(T)), this presents a challenge for families and clinicians. The purpose of this study was to explore how decisions are made in the management and treatment of X(T) and what can be done to support decision-making for clinicians, parents and children. METHODS: This was a qualitative study using face to face interviews with consultant ophthalmologists and orthoptists, and parents of children with X(T). Interview data were analysed using the constant comparative method. RESULTS: The drivers for clinicians in treatment decision-making for X(T) were the proportion of time the strabismus is manifest and parents’ views. For parents, decisions were influenced by: fear of bullying and, to a lesser degree, concerns around the impact of the strabismus on their child’s vision. Uncertainty around the effectiveness of treatment options caused difficulties for some clinicians when communicating with parents. Parental understanding of the nature of X(T) and rationale for treatment often differed from that of the clinicians, and this affected their involvement in decision-making. Though there were good examples of shared decision-making and parent and child engagement some parents said the process felt rushed and they felt excluded. Parents reported that clinicians provided sufficient information in consultations but they had difficulties in retaining verbal information to convey to other family members. CONCLUSIONS: Overall parents were happy with the care their child received but there is scope for better parent and (where appropriate) child engagement in decision-making. There was an expressed need for written information about X(T) to reinforce what was given verbally in consultations and to share with other family members. Access could be via the hospital website, along with videos or blogs from parents and children who have undergone the various management options. A method of assisting clinicians to explain the treatment options, together with the uncertainties, in a clear and concise way could be of particular benefit to orthoptists who have the most regular contact with parents and children, and are more likely to suggest conservative treatments such as occlusion and minus lenses.

A rare cause of focal segmental glomerulosclerosis: Sarcoidosis

A 58-year-old female patient diagnosed as having sarcoidosis 23 years ago developed nephrotic syndrome. No pathology was found which could explain this, so it was attributed to her sarcoidosis. Renal biopsy showed global and segmental sclerosis. The occurrence of focal segmentary glomerulosclerosis in a case of sarcoidosis is rare. In systemic sarcoidosis it is thought that T-cell dysfunction may play a role in the pathogenesis of glomerulonephritis. When treatment is considered, corticosteroid therapy may be used according to the clinical status at diagnosis as well as on follow-up of the patient. Copyright (C) 2002 S. KargerAG, Basel
