    Notes: Twenty-four wheat cultivars and breeding lines were screened for isolate-specific resistance to septoria tritici blotch (STB) caused by 12 isolates of Mycosphaerella graminicola. New isolate-specific resistances that could be used in wheat breeding were identified. Major sources of resistance to STB used in world breeding programmes for decades, such as Kavkaz-K4500, Veranopolis, Catbird and TE9111, have several isolate-specific resistances. This suggests that ‘pyramiding’ several resistance genes in one cultivar may be an effective and durable strategy for breeding for resistance to STB in wheat. Several cultivars, including Arina, Milan and Senat, had high levels of partial resistance to most isolates tested as well as isolate-specific resistances. Resistance to isolate IPO323 was common, present in all but one of the major sources of resistance tested. This suggests that resistance to IPO323 may be an indicator of varietal resistance to STB in the field.

    Notes: Background  Surgery for undescended testes is recommended before the age of 2 years. However, boys are still undergoing surgery for undescended testes at a much later age than recommended.Methods  An initial audit reviewed all orchidopexies performed at Northampton General Hospital between 1992 and 1994. This demonstrated that only 19% of boys had surgery by the age of 2 years, and the key reason for late surgery was late referral. Guidelines for referral of undescended testes were established in which referral to a surgeon was advised following the 8-month child health surveillance check if undescended testis was suspected. This would enable surgery before the age of 2 years. Audit results were disseminated and we implemented a package of measures based on evidence based change management techniques. These included written advice to general practitioners (GPs), a parent information leaflet and an amended personal child health record advising timing of referral. A reminder to the GP to refer following the 8-month check was generated using computer recall from the Child Health System records. Guideline implementation was monitored by annual audit and feedback.Results  The baseline audit for the years 1992–94 found a median age at surgery of 4 years. Implementation of the new policies in 1998 resulted in a reduction in median age at surgery to 2.0 years in the 12 months ending September 2001.Conclusions  While concern about the age at orchidopexy has been highlighted in many previous studies, this is the first to show that improvement in the age at orchidopexy can be achieved. Implementing locally agreed guidelines with written information to GPs and parents combined with computerized recall from Child Health System records achieved the target within 3 years. Similar systems could be implemented nationally at minimal cost.

    Notes: The effect of increased flow on movement and microhabitat use of Atlantic salmon Salmo salar parr in winter was investigated using radiotelemetry. To simulate hydropeaking operations, flow was increased four-fold from 1·3 m3 s−1 to 5·2 m3 s−1 for 24 h periods. Flow did not affect fish habitat use or displacement and had little effect on fish activity within diel periods. During high flow periods in late winter, fish reduced night-time activity. Stranding rates during flow reduction were also very low (only one fish).
