2.  Management of childhood diarrhoea by pharmacists and parents: is Britain lagging behind the Third World? 
BMJ : British Medical Journal  1991;302(6774):440-443.
OBJECTIVE--To investigate the role of community pharmacists in providing advice and treatment for children with diarrhoea; to investigate mothers' responses to diarrhoea in their children. DESIGN--Cross sectional questionnaire study of a random selection of community pharmacists and of mothers attending child health clinics. Pharmacists were interviewed and given a questionnaire and a separate group was visited by a researcher posing as a parent; mothers were interviewed at the clinic. SETTING--Newcastle upon Tyne. SUBJECTS--20 pharmacists were interviewed and visits by a researcher posing as a parent were carried out to 10 different pharmacists; 58 mothers were interviewed. MAIN OUTCOME MEASURES--Advice given by pharmacists was contrasted with standard advice on management of diarrhoea in children. RESULTS--Half of the pharmacists interviewed and 70% of pharmacists visited by a researcher posing as a parent recommended inappropriate treatment of childhood diarrhoea (such as antidiarrhoeal drugs and withholding breast milk), and only 30% at interview stated that they would ask for the age of the child. Mothers' knowledge of home treatment was inadequate. All pharmacists in the posed visits recommended a purchased treatment. CONCLUSION--Pharmacists are widely used by parents for consultation for children's ailments but their advice is not always appropriate; hence they should be given more consistent training in recognising and managing clinical problems. Medical advice on management of diarrhoea is also inconsistent and should be modified to conform to the guidelines of the World Health Organisation.

3.  Germline excision of the transposable element Tc1 in C. elegans. 
Nucleic Acids Research  1991;19(20):5669-5672.
We have examined eight germline revertants generated by the excision of Tc1 from a site within the unc-22 gene of Caenorhabditis elegans. A rich variety of rearrangements accompanied Tc1 excision at this site, including transposon 'footprints', deletions of sequences flanking the insertion site and direct nontandem duplications of flanking DNA. With only modest modification the double-strand gap repair model for transposition, recently proposed by Engles and coworkers (Cell 62: 515-525 1990), can explain even the most complex of these rearrangements. In light of this model rearrangements of the target site accompanying transposition/excision may not be the end result of imprecise excision of the element. Instead, these rearrangements may be the result of imprecise repair of the double-strand gap by the host replication and repair machinery. Sequences surrounding an insertion site influence the fidelity of gap repair by this machinery. This may lead to a number of possible resolutions of a double-strand gap as documented here for a Tc1 site in unc-22.
