RESUMEN
BACKGROUND: The evidence base underlying clinical practice in children's general surgery is poor and high-quality collaborative clinical research is required to address current treatment uncertainties. The aim of this study was, through a consensus process, to identify research priorities for clinical research in this field amongst surgeons who treat children. METHODS: Questions were invited in a scoping survey amongst general surgeons and specialist paediatric surgeons. These were refined by the study team and subsequently prioritized in a two-stage modified Delphi process. RESULTS: In the scoping survey, a total of 226 questions covering a broad scope of children's elective and emergency general surgery were submitted by 76 different clinicians. These were refined to 71 research questions for prioritization. A total of 168 clinicians took part in stage one of the prioritization process, and 157 in stage two. A 'top 10' list of priority research questions was generated for both elective and emergency general surgery of childhood. These cover a range of conditions and concepts, including inguinal hernia, undescended testis, appendicitis, abdominal trauma and enhanced recovery pathways. CONCLUSION: Through consensus amongst surgeons who treat children, 10 priority research questions for each of the elective and emergency fields have been identified. These should provide a basis for the development of high-quality multicentre research projects to address these questions, and ultimately improve outcomes for children requiring surgical care.

A retrospective analysis of 1366 cervical polyps showed that none had malignant features and 67% were removed from asymptomatic women. A policy removing only cervical polyps from symptomatic women or those with abnormal cervical cytology and limiting histological examination to these polyps would result in significant savings and reduce the small risk of morbidity associated with polypectomy.

BACKGROUND: Strategies for the surgical management of necrotising enterocolitis are various and controversial. OBJECTIVE: To characterise variation in surgical management of this disease across the United Kingdom. METHODS: Postal survey of 104 consultant paediatric surgeons with a 77% response rate. RESULTS: Duration of antibiotic treatment (median 10 days, range 6-14), time until the start of enteral feeding (median 10 days, range 4-21), and absolute indications for surgery all vary between surgeons. Peritoneal drainage is used by 95% of surgeons. Forty two percent use it in neonates of all weights, whereas 36% restrict its use to those <1000 g. Peritoneal drainage is used for stabilisation by 95% and as definitive treatment by 58%. At laparotomy, operative procedures include diverting jejunostomy, resection and stoma, resection with primary anastomosis, and "clip and drop". All procedures are used in infants of all weights except resection and primary anastomosis, which is used predominantly in larger infants (55% in <1000 g; 77% in >1000g; p=0.005). Infants may be considered too unwell for peritoneal drainage by 11% of surgeons compared with 90% for laparotomy (p<0.0001). CONCLUSIONS: There is considerable variation in surgical strategies for necrotising enterocolitis. Peritoneal drainage is used by most surgeons, with controversial indications and expectations. The use of resection and primary anastomosis is influenced by the weight of the neonate.

Imposex, the phenomenon in which induced male sex characteristics are superimposed on normal females, still occurs widely in the gastropod Thais orbita from Port Philip Bay, and its incidence is greatest in areas that have high boating and shipping activities. Compared to 1992, both the extent and severity of imposex has reduced. By inference, this means that pollution by tributyltin (TBT) in Port Phillip Bay has decreased and that the bans limiting its use to vessels greater than 25 m in length, in place since 1989, have been effective. However, TBT pollution is still an issue at locations that are adjacent to major ports, such as the Port of Melbourne, where TBT from large ships and ship maintenance activities continues to pollute fish habitats. It is anticipated that the incidence of imposex, and therefore TBT pollution, will continue to decrease in Port Phillip Bay as long as the bans currently in place continue to be observed. If the trends observed in the present study continue, then it is unlikely, with the notable exception of commercial ports, that TBT will pose a threat to the health of fish habitats in Port Phillip Bay.

The effect of sodium meclofenamate on the binding of [3H]prostaglandin E2 [( 3H]PGE2) to membranes from human myometrium was investigated. Meclofenamate inhibited the binding of [3H]PGE2 to high-affinity (dissociation constant 1.5 nmol/l) sites in a reversible dose-dependent manner (inhibition constant 11 mumol/l). The mechanism of inhibition was mainly competitive, but at high doses of meclofenamate (greater than or equal to 100 mumol/l) there was loss of PGE receptor sites. Of several PG synthesis inhibitors tested, only meclofenamate and, to a lesser extent, mefenamic acid had a significant inhibitory effect. PGE2 stimulated cyclic AMP generation in slices of human myometrium and this was inhibited by meclofenamate in a dose-dependent manner (50% inhibition occurred at 9 mumol/l). Again, this effect was specific for meclofenamate and fitted a competitive mechanism at doses in the range 1-10 mumol/l and a non-competitive mechanism at higher doses. The data show that meclofenamate, in addition to its traditional role as a PG synthesis inhibitor, affects directly PGE receptor binding and activation.

OBJECTIVE: To investigate the nature of work related to the menopause in general practice. DESIGN: Questionnaire study over six months among general practitioners after each consultation with a woman aged 40-69 at which issues related to the climacteric had been discussed. SETTING: 9 General practices in the Oxford area. SUBJECTS: 416 Women who had 572 consultations. MAIN OUTCOME MEASURES: Age, menopausal state, and first or subsequent consultation. Symptoms were classified together with the treatment and the outcome of the consultation. RESULTS: The consultation rate varied greatly between practices, the overall rate being 4.4%. There were many premenopausal women and women in their 60s presenting; women with hysterectomies presented more often--36% (37/103) of women with hysterectomies had more than one consultation compared with 26% (38/144) for premenopausal women and 24% (38/155) for postmenopausal women. 409 women had symptoms and 218 were prescribed oestrogen treatment. 156 of the consultations involved discussion and advice only. Only four women were referred to a local specialist clinic. CONCLUSION: There is a low overall use of hormone replacement therapy in the general postmenopausal population despite the recent media coverage of its benefits in the prevention of osteoporosis and subsequent fractures.
