Eradication of 'ooHelicobacter pylori'ox : an objective assessment of current therapies

The purpose of the present review was to determine objectively the optimal treatment for the eradication of H. pylori amongst the currently used regimens. A comprehensive literature search provided a data-base relating to the following treatments: dual therapy with an anti-secretory drug plus either amoxycillin or clarithromycin; standard triple therapy, with or without additional anti-secretory drugs; proton pump inhibitor triple therapy; and H₂-receptor antagonist triple therapy. Emphasis was placed on intention-to-treat analyses of eradication rates using all of the available evidence. The criteria used to select the optimal treatment were efficacy (eradication rates), frequency of side-effects, simplicity of the regimen (number of tablets per day and duration of treatment) and cost. The analysis showed that proton pump inhibitor triple therapy (that is, a proton pump inhibitor plus any two of amoxycillin, clarithromycin or a nitroimidazole) was the preferred treatment for the eradication of H. pylori . In particular, the 1-week, low-dose regimen with omeprazole plus clarithromycin plus tinidazole produced the highest eradication rates (>90%) with the lowest frequency of side-effects and at only modest cost.     

Mentoring in inservice training for child care workers

A model for training the trainers of child care providers that employs Vygotsky's framework of the Zone of Proximal Development is described. This efficient training mechanism proposes mentoring relationships as a means to meet the developmental needs of experienced child care professionals and improve the quality of existing child care programs.The authors would like to thank Dr. Bille Thomas and the satellite resource center directors and staff members for their work on the project.     

APOE epsilon3 gene transfer attenuates brain damage after experimental stroke.

Apolipoprotein E (apoE, protein; APOE, gene) is the major lipid-transport protein in the brain and plays an important role in modulating the outcome and regenerative processes after acute brain injury. The aim of the present study was to determine if gene transfer of the epsilon3 form of APOE improves outcome in a murine model of transient focal cerebral ischaemia. Mice received an intrastriatal injection of vehicle, a second-generation adenoviral vector containing the green fluorescent protein gene (Ad-GFP) or a vector containing the APOE epsilon3 gene (Ad-APOE) 3 days before 60 mins focal ischaemia. Green fluorescent protein expression was observed in cells throughout the striatum and subcortical white matter indicating successful gene transfer and expression. ApoE levels in the brain were significantly increased after Ad-APOE compared with Ad-GFP or vehicle treatment. Ad-APOE treatment reduced the volume of ischaemic damage by 50% compared with Ad-GFP or vehicle treatment (13+/-3 versus 29+/-4 versus 27+/-5 mm(3)). The extent of postischaemic apoE immunoreactivity was enhanced in Ad-APOE compared with Ad-GFP or vehicle treated mice. These results show the ability of APOE gene transfer to markedly improve outcome after cerebral ischaemia and suggest that modulating apoE levels may be a potential strategy in human stroke therapy.     

Congential dislocation of the hip and adult low back pain: a report of three cases

Congenital dislocation of the hip (CDH) in an adult can accompany or cause mechanical low-back pain. This in turn, can create confusion in making the proper diagnosis. The mechanical alterations caused by CDH create an added strain to the lumbosacral spine. Manipulative treatment for back pain in these patients must not subject the dislocated hips to undue torque.     

Spinal dysraphism and cavovarus foot deformity: a case report

Neurological impairment secondary to spinal dysraphism most commonly presents as unilateral cavovarus foot in children. The deformity usually develops in the growing child around the age of five or six. The presence of a cavovarus foot of unknown origin in a child should lead to a complete neurological examination, including an assessment of the spine for spinal dysraphism. The early recognition of pathology may prevent severe neurological sequelae. A case of lipomyelomeningocele is presented to illustrate that cord damage in children with spinal dysraphism can present initially as a cavovarus foot.     

Acute intermittent porphyria and mental illness – a family study

All cases of acute intermittent porphyria (AIP) are believed to be caused by a mutation in the gene encoding for porphobilinogen deaminase, a rate-limiting enzyme in the haem synthetic pathway. This gene has been mapped to the long arm of chromosome 11, a region of the genome that has recently attracted considerable attention as a possible location for genes implicated in major mental disorder. This study was designed to show whether major mental illness co-segregated with acute intermittent porphyria in families where the two conditions are found. The study also investigated the relation between clinical mental symptoms and biochemical parameters of acute intermittent porphyria. The case records of 344 consecutive patients admitted to the Porphyrias Research Group in the Western Infirmary in Glasgow between 1950 and 1988 with acute intermittent porphyria were examined for evidence of psychiatric contact. Of 16 individuals identified, 12 were available for the study. Forty relatives of these 12 probands, including 9 who were asymptomatic carriers of AIP, were interviewed for lifetime history of mental illness and current symptoms. Comparisons were made between 4 groups of patients based on urinary porphyrin levels and erythrocyte enzyme activity; 1) manifest acute intermittent porphyria, 2) latent acute intermittent porphyria, 3) normal relatives and 4) total acute intermittent porphyria (latent and manifest combined). No association was found between AIP and schizophrenia or manic-depressive illness. Only one patient with schizophrenia was found in the sample of 344 case notes, and in 2 families bipolar illness was found but did not segregate with acute intermittent porphyria. The commonest psychiatric diagnosis in patients was generalized anxiety. In the total AIP group (latent and manifest), compared with normals, the rating scale measures of anxiety were significantly correlated with the level of porphyrin metabolites in the urine at the time of rating. This was true even in subjects with latent AIP, who were not at the time of testing aware that they were asymptomatic carriers of the illness. AIP should be considered in the differential diagnosis of generalized anxiety disorder.
