Metronidazole in the Prophylaxis and treatment of Anaerobic Infection
The influence of prophylactic metronidazole on vaginal
carriage rates of anaerobes and the development of postoperative
anaerobic infection was studied in 104 women
who underwent abdominal hysterectomy. Metronidazole
prophylaxis in 54 patients led to a decrease in the anaerobe
vaginal carriage rate from 65% pre-operatively to
17% and 28% on the 3rd and 7th postoperative days respectively.
In the control group (50 patients) no significant
decrease in anaerobe yield was noted, corresponding percentages
being 72%, 64%, and 74%. Postoperative infection
occurred in 36 patients (28 controls; 8 on prophylactic
metronidazole). Wound swabs from all 8 patients in
the latter group yielded aerobes, and in 1 patient mixed
infection (aerobes/anaerobes) occurred. In 7 of these
patients (including the patient with mixed infection), the
infection resolved spontaneously, while the 8th patient
responded to therapy with metronidazole, kanamycin and
ampicillin. In the control patients, 21 cases of postoperative
wound infection and 4 of vault infection were seen;
wound swabs from patients in the former group yielded
aerobes in only 6 cases, and mixed growth of aerobes/
anaerobes in 10 cases. Postoperative wound/vault infections
in control patients cleared spontaneously in 18 cases
and responded to imidazole therapy, with or without ampicillin
and kanamycin, in 7 cases.Web of Scienc
Red Devonian trilobites with green eyes from Morocco and the silicification of the trilobite exoskeleton
Latest Emsian (Early Devonian) sediments at the famous mudâmoundâ and trilobiteâlocality Hamar Laghdad (Tafilalt,
Morocco) yielded some redâcoloured remains of phacopid trilobites. Closer examination revealed that the eyes of these phacopids are often greenish in colour. EDXâanalyses showed that the lenses retained their original calcitic composition, possibly greenish due to Feâimpurities, while most of the exoskeleton was silicified. The silicified parts contain elevated concentrations of iron which causes the red colour. This phenomenon is explained by the porosity of the exoskeleton in contrast to the homogeneous and massive construction of the lenses and their Mgâcontent. These incompletely silicified trilobites enabled a reconstruction of the silicification process in trilobites. Their diagenetic alteration probably occurred as a result of events associated with the Cretaceous transgression

Geography, pedagogy and politics
This Forum takes seriously the proposition that everything we do as geographers is potentially `relevant\u27 to the affairs of the wider society. Using expanded conceptions of `pedagogy\u27 and `politics\u27, the Forum suggests why and how we are always engaged in processes of shaping and steering this wider society, wittingly or not, and intentionally or not. In the minds of many of us, this shaping and steering only (or mostly) occurs through activities we assume to be self-evidently `relevant\u27 in intention or effect - like undertaking policy-relevant research. However, this Forum argues that it is misplaced to regard only a select group of our activities as socially consequential. Pulling together recent debates on `participatory\u27, `activist\u27 and `public\u27 geographies, the Forum offers arguments and examples that show readers the potential relevance of the whole range of diverse practices in which we professionally engage. The introduction and five subsequent contributions together suggest that we aim for a `joined-up\u27 conception of ourselves and our activities as professional geographers embedded in a wider society. As such, the Forum aims to make a distinctive contribution to ongoing discussions of how big-G academic geography relates to the plethora of small-g quotidian geographies - imagined and real - that are the stuff of our world
