    Notes: Summary We have tested the suggestion that the reported increase, in hypoxic rats, in the number of lung endocrine cells immunoreactive for the regulatory peptide CGRP is caused by an accumulation of peptide within the cells which renders them more detectable, rather than by a real increase in proliferation. The incorporation of continuously infused 5′-bromodeoxyuridine (BrdU) into nuclei of CGRP-containing cells was studied by immunohistochemistry in the airway and respiratory epithelium of rats kept in a hypoxic (10% O2), normobaric conditions for 7 days and in normoxic, normobaric controls. Some CGRP-immunoreactive cells could also be labelled for BrdU. However, the ratio of the number of cells labelled with both CGRP and BrdU to the number of cells labelled with CGRP alone did not differ significantly between hypoxic and normoxic rats (7.1±0.7 and 6.1±1.2, respectively; mean±SEM; P=0.49). These data strongly suggest that CGRP-containing endocrine cells or their precursors do proliferate in adult rat lung, but that the proliferation is not increased significantly in hypoxia.

    Notes: Abstract Objective The effect of selective decontamination of the digestive tract (SDD) on Intensive Therapy Unit (ITU)-acquired enterococcal infection and colonization was studied. Changes in the predominant species isolated and resistance patterns to antimicrobial agents were also studied. Design Three groups were investigated: historical control (HC), contemporaneous control (CC) and patients receiving SDD (topical polymyxin, amphoterecin B and tobramycin throughout ITU stay with intravenous ceftazidime for the first 3 days only). Setting Adult general ITU with 7 beds. Patients Patients with a nasogastric tube in situ and who were likely to remain in ITU for 48 h or longer were recruited. Results Enterococcal infections occured in 3 of 84 HC patients and 2 of 91 CC patients. There were no unit-acquired enterococcal infections in the SDD group. There were 140 episodes of enterococcal colonization occurring in 112 patients, with significantly more in the SDD and CC groups (p〈0.05. There were no significant differences in antibiotic sensitivities between the three groups.Enterococcus faecalis was the most frequently isolated species. Conclusion SDD does not predispose to enterococcal infection but does encourage colonization in patients receiving the regimen and other patients in ITU at the same. There is a complex interaction of factors which influence faecal flora and the likelihood of patients becoming colonized or infected with enterococci.

    Notes: Summary Six patients experienced falling spells concurrent with the intake of antidepressant drugs in high doses or in moderate doses combined with other psychotropic drugs. The close temporal correlation between drug ingestion and the falling spells and their immediate termination after reduction or discontinuation of medication suggests that these drugs caused the falls. Further factors predisposing to the falling spells remain to be defined.
