Although the etiology of nonsyndromic forms of craniosynostosis remains uncertain, recent experiments from our laboratory have demonstrated that fetal head constraint induces cranial suture fusion in mice through a process associated with altered patterns of transforming growth factor beta (TGF-beta) isoform expression. Other recent studies have highlighted(More)
The cytolethal distending toxin (Cdt) of Actinobacillus actinomycetemcomitans, a periodontal pathogen, is a newly described cytotoxin with immunosuppressive properties, capable of causing cell cycle arrest of lymphocytes. The objectives of this study were to investigate the occurrence of A. actinomycetemcomitans with the cdt genotype in the subgingival(More)
In view of both the delay in obtaining identification by conventional methods following blood-culture positivity in patients with candidaemia and the close relationship between species and fluconazole (FLC) susceptibility, early speciation of positive blood cultures has the potential to influence therapeutic decisions. The aim was to develop a rapid test to(More)
OBJECTIVES To evaluate the impact of selective fluconazole prophylaxis on incidence of invasive fungal infection and emergence of fluconazole resistance in neonatal intensive care. DESIGN Retrospective study of very low birthweight (VLBW) babies (<1500 g birth weight) admitted to a neonatal intensive care unit (NICU) in the period 1 year before and after(More)
Cohorting bronchiolitis patients infected with respiratory syncytial virus (RSV) and/or influenza viruses is paramount in preventing cross-infection of these viruses in hospital. Nested polymerase chain reaction (nPCR) was compared with immunofluorescence (IF) for the detection of RSV subtypes A and B in children with suspected bronchiolitis. Co-infection(More)
Although the introduction of automated blood culture systems has dramatically reduced laboratory personnel bench time, 48 to 72 h is still required for the identification of pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus (MSSA) and the accurate determination of antimicrobial sensitivities for prompt(More)
BACKGROUND respiratory adenoviruses are common, often resulting in serious sporadic and epidemic infections and impaired immunity can dramatically increase their severity. They are now thought capable of establishing latency. Diagnosis by culture is slow while direct antigen detection by immunofluorescence lacks sensitivity. Molecular diagnosis can be both(More)
OBJECTIVE To determine, within a representative population group of men and women, whether alteration of the lipid profile might underlie the reported association between Chlamydia pneumoniae and ischaemic heart disease. DESIGN AND SETTING Cross sectional survey in an area with a high incidence of ischaemic heart disease. SUBJECTS 400 randomly selected(More)
BACKGROUND The association of Chlamydia pneumoniae with atherosclerosis is controversial. We investigated the presence of C. pneumoniae and other Chlamydia spp. in atheromatous carotid artery tissue. METHODS Forty elective carotid endarterectomy patients were recruited (27 males, mean age 65 and 13 females mean age 68), 4 had bilateral carotid(More)
The impact of shedding of herpes simplex virus type 1 (HSV-1) on hospital survival of patients receiving assisted ventilation in an adult tertiary referral, acute trauma intensive care unit was assessed. The study was designed to address a clinical impression linking HSV-1 recovery with poor survival. Two hundred and forty-one males and 152 females were(More)
