Puerperal streptococcal toxic shock syndrome treated with recombinant human activated protein C and intravenous immunoglobulin.

Group A streptococcal sepsis is an uncommon management challenge and has a potentially fulminate course. We present the case of a 25-year-old woman who, within 24h of spontaneous vaginal delivery at 32 weeks of gestation, developed signs of systemic infection and multi-organ failure requiring admission to the intensive care unit. Recombinant human activated protein C and intravenous immunoglobulin were used; subsequently heparin-induced thrombocytopenia and pulmonary embolus also required treatment.

Changes in transthoracic impedance during sequential biphasic defibrillation.

Introduction: Sequential monophasic defibrillation reduces transthoracic impedance (TTI) and progressively increases current flow for any given energy level. The effect of sequential biphasic shocks on TTI is unknown. We therefore studied patients undergoing elective cardioversion using a biphasic waveform to establish whether this is a phenomenon seen in the clinical setting.

Plasma concentrations and sedation scores after nebulized and intranasal midazolam in healthy volunteers.

Background: An efficacious, reliable, and non-invasive route of administration for midazolam, a drug used for sedation and pre-anaesthetic medication, would have obvious advantages. This study compares two potential methods of administering midazolam by the nasal and nebulized routes.

Methods: Midazolam (0.

Unexpectedly high incidence of indigenous acute hepatitis E within South Hampshire: time for routine testing?

Hepatitis E indigenous to developed countries (hepatitis EIDC) is a form of hepatitis E in persons with no travel history to highly endemic areas. It has been recognized recently as an emerging clinical entity in a significant number of economically developed countries including UK. However, it is still perceived as a rare disease and routine laboratory testing for hepatitis E is not performed.

Infliximab delays but does not avoid the need for surgery in treatment-resistant pediatric Crohn' disease.

The aim of this study was to review the impact of infliximab therapy on children with treatment-resistant Crohn's disease. Treatment resistance was defined as clinically active disease despite >4 months of immunosuppressive therapy. The outcome variables were time to first remission, duration of remission and the need for surgery.

Zellweger syndrome resulting from maternal isodisomy of chromosome 1.

Zellweger syndrome (ZS) is an autosomal recessive peroxisomal disorder that results from mutations in one of the peroxisome biogenesis (PEX) genes. This is the first patient reported with uniparental disomy (UPD) resulting in ZS, in this case maternal isodisomy of chromosome 1 involving reduction to homoallelism of a frameshift mutation within PEX 10. Other reported cases of UPD1, and evidence for the imprinting of genes on chromosome 1, are reviewed.

Anaphylaxis to foods.

Three crucial areas of the management of anaphylaxis due to food allergy are discussed: making a diagnosis, deciding who needs a self-injectable adrenaline device and spotting the novel allergen. Managing children and teenagers with anaphylaxis is challenging due to the lack of available evidence that specific addresses these issue. The available evidence is presented and discussed.

An analytical technique to recover the third dimension in planar imaging of inhaled aerosols--2 estimation of the deposition per airway generation.

An analytical algorithm has been recently described for converting planar scintigraphic images of aerosol distributions in the lungs to an equivalent three-dimensional (3D) representation. The recovery of the volumetric information has opened up to planar imaging the possibility of measuring aerosol deposition per airway generation. This paper investigates the accuracy and precision of the generation analysis achievable with planar imaging using simulation.

An evaluation of the value of group education in recently diagnosed diabetes mellitus.

Diabetic patients have a 12% to 25% lifetime risk of developing foot complications leading to significant morbidity and mortality. The objective of this study was to assess the effectiveness of group education in improving patient awareness of foot care. The authors evaluated the effect of group size and areas in which knowledge seemed to be most affected.

Analytical technique to recover the third dimension in planar imaging of inhaled aerosols: (1) impact on spatial quantification.

An analytical algorithm is described for converting planar scintigraphic images of aerosol distributions in the lungs to an equivalent three-dimensional (3D) representation. The recovery of volumetric information should benefit regional quantification. The technique has been validated using simulated planar images of eleven known aerosol distributions in ten realistic lungs.

'Setting new standards for acute care' the society for acute medicine international conference, 1-2 october 2007.

The Scottish Exhibition and Conference Centre provided the venue for the first truly International meeting of the Society for Acute Medicine in early October. Almost 600 delegates were treated to some unseasonal Glasgow sunshine and traditional Scottish hospitality, as they enjoyed the varied programme put together by Mike Jones, Derek Bell and Liz Myers. The long distance that the Society has travelled in the past 7 years to reach this size was emphasised repeatedly over the two days; in his inaugural address to the society as incoming President, Dr Rhid Dowdle told us that SAM is now playing in a much bigger league than ever before, but cautioned that the speciality still has a way to go to reach the 'top division'.

Late relapse of metastatic non-seminomatous testicular germ cell tumours.

Although the majority of men presenting with non-seminomatous germ cell tumours (NSGCT) are cured, late relapse (occurring more than 2 years after obtaining a complete response to treatment) is increasingly recognized. The typical patterns of disease spread have been well-documented, but the findings at late relapse are more variable and less well-described. We discuss the phenomenon of late relapse, the characteristics of teratoma differentiated (TD), and the issue of long-term imaging surveillance of patients with NSGCT.

Perioperative fluid therapy in children: a survey of current prescribing practice.

Background: Fluid therapy in children may be associated with iatrogenic hyponatraemia. We surveyed anaesthetists' current fluid prescribing practice during the perioperative period, departmental fluid protocols and awareness of the concerns of the Royal College of Paediatrics and Child Health (RCPCH) about the use of dextrose 4%/saline 0.18% in children.

Quantification of [123I]FP-CIT SPECT brain images: an accurate technique for measurement of the specific binding ratio.

Purpose: A technique is described for accurate quantification of the specific binding ratio (SBR) in [(123)I]FP-CIT SPECT brain images.

Methods: Using a region of interest (ROI) approach, the SBR is derived from a measure of total striatal counts that takes into account the partial volume effect. Operator intervention is limited to the placement of the striatal ROIs, a task facilitated by the use of geometrical template regions.

Post-shock myocardial stunning: a prospective randomised double-blind comparison of monophasic and biphasic waveforms.

Introduction: Compared with monophasic defibrillation, biphasic defibrillation is associated with less myocardial stunning and earlier activation of sodium channels. We therefore hypothesised that earlier sodium channel activation would result in earlier restoration of the first sinus beat following elective DC cardioversion.

Methods: Adults undergoing elective DC cardioversion were randomised to receive either monophasic or biphasic escalating transthoracic shocks.

Thresholds of allergenic proteins in foods.

Threshold doses or Estimated Eliciting Doses (EEDs) represent an important new field of research in food allergy. Clinicians and regulators have embraced some toxicological concepts such as LOAEL and NOAEL and applied them to an area of significant clinical uncertainty and interest. The impact of intrinsic human factors (e.

Kabuki syndrome: new ocular findings but no evidence of 8p22-p23.1 duplications in a clinically defined cohort.

The underlying cause of the multiple congenital anomalies/mental retardation syndrome Kabuki syndrome (KS, OMIM 147920) has not yet been established. We identified seven patients who fulfilled the classical clinical criteria for this syndrome and undertook a detailed clinical, ophthalomological and molecular cytogenetic review. Three of the seven patients had previously undetected ocular anomalies including myopia, ptosis, strabismus and tilted discs.

External defibrillation in the left lateral position--a comparison of manual paddles with self-adhesive pads.

Introduction: Firm paddle force during defibrillation lowers transthoracic impedance (TTI) and increases transmyocardial current, increasing the chances of successful cardioversion. Current protocols recommend that if defibrillation using the anterior-apical (AA) paddle position fails, the anterior-posterior (AP) position should be used. This generally requires the patient to be placed in the left lateral position with the operator leaning over the patient.

Virilisation in a case of transitional cell carcinoma of the ovary.

A 52 year old woman presented with a five month history of emotional changes, voice changes, and of abdominal discomfort. Clinical, biochemical, and radiological examinations showed evidence of virilisation, raised testosterone, and a complex ovarian mass. Microscopy of the resection specimen showed the tumour to be a transitional cell carcinoma of the ovary with luteinisation and hyperplasia of the intervening stromal cells.

The views of children and their families on being in hospital.

This study aimed to elicit the separate views of children, young people and carers after a period in hospital as an inpatient. Questionnaires were administered to 130 children and their families discharged after a period as hospital inpatients in January 2003. Anonymized data were returned from 50 families.
