The emergence of oseltamivir-resistant pandemic influenza A (H1N1) 2009 virus amongst hospitalised immunocompromised patients in Scotland, November-December, 2009.

To investigate the frequency of oseltamivir resistance in circulating strains of the 2009 influenza A(H1N1) pandemic virus in Scotland, 1,802 samples from 1,608 infected hospitalised patients were screened by the H275Y discriminatory RT-PCR. Among these, we identified 10 patients who developed the H275Y mutation. All of them were immunocompromised and were under treatment or had been treated previously with oseltamivir.

Specialist team retrieval of head injured patients: fact, fiction, or formula?

Objective: This feasibility study aimed to determine the maximum theoretical distance the Edinburgh Paediatric Retrieval Team (EPRT) could travel to retrieve head injured children without additional delay in reaching definitive care.

Design: A prospective audit was conducted over 2 years to determine the current practice for paediatric head injury transfers (stabilisation, referral, and transfer time) undertaken by primary hospital staff, and the performance (mobilisation and travel time) of the EPRT. A novel formula was devised and used to determine the theoretical maximum radius within which the EPRT could reach a referring hospital during their stabilisation of head injured patients.

The effect of nitrous oxide on cerebral blood flow velocity in children anaesthetised with sevoflurane.

To determine the effects of nitrous oxide on middle cerebral artery blood flow velocity (CBFV) during sevoflurane anaesthesia in children, CBFV was measured using transcranial Doppler sonography in 16 ASA I or II children. Anaesthesia consisted of 1.0 MAC sevoflurane in 30% oxygen with intermittent positive pressure ventilation maintaining FEco2 at 38 mmHg (5.

The effect of sevoflurane on cerebral blood flow velocity in children.

Background: Sevoflurane is a suitable agent for neuroanesthesia in adult patients. In children, cerebrovascular carbon dioxide reactivity is maintained during hypo- and normocapnia under sevoflurane anesthesia. To determine the effects of sevoflurane on middle cerebral artery blood flow velocity (Vmca) in neurologically normal children, Vmca was measured both at different MAC values and at one MAC over a specified time period, using transcranial Doppler sonography.

Cerebrovascular carbon dioxide reactivity in children anaesthetized with sevoflurane.

Background: To determine the effects of sevoflurane on cerebrovascular carbon dioxide reactivity (CCO2R), middle cerebral artery blood flow velocity (CBFV) was measured at different levels of PE'CO2 by transcranial Doppler sonography in 16 ASA I or II children, aged 18 months to 7 yr undergoing elective urological surgery.

Methods: Anaesthesia comprised 1.0 MAC sevoflurane and air in 30% oxygen delivered through an Ayre's T piece by intermittent positive-pressure ventilation, and a caudal epidural block with 0.

Laparoscopic fundoplication in children: anaesthetic experience of 51 cases.

We report the anaesthetic management and outcomes of our first 51 laparoscopic fundoplications. Case records of the 50 patients (one redo), median age 6 years (5 months to 20 years), were reviewed. Median duration of anaesthesia was 120 (60-300) min.

Effects of oxidant air pollutants on western pine beetle (Coleoptera: Scolytidae) populations in southern California.

The attack rates, brood survival, and emergence rates of the western pine beetle, Dendroctonus brevicomis LeConte, and incidence of entomophagus associates, were compared between photochemical oxidant damaged, and apparently healthy, ponderosa pine trees, Pinus ponderosa Dougl. ex Laws in the San Bernardino Forest in Southern California. The results from this study suggest that oxidant-damaged trees attacked by western pine beetle produced about the same total brood with lower initial attacks when compared with healthier trees, whereas the numbers of predators and parasitoids were higher in the healthier trees.

Partial purification and characterisation of the human skin fibroblast androgen receptor: detection of abnormal receptor complexes in cells from patients with androgen insensitivity syndromes.

After incubation of hGSF with [3H]5 alpha-dihydrotestosterone, 17 beta-hydroxy-7 alpha, 17 alpha-dimethyl-4-estrene-3-one, or 17 beta-hydroxy-17 alpha-methyl-4,9,11-estrien-3-one, androgen-receptor complexes were extracted with 0.5 M KCl and precipitated by 35% ammonium sulphate. Receptor complexes from control hGSF sedimented at approximately 4S on linear 5-20% sucrose gradients.
