Broiler resilience to colibacillosis is affected by incubation temperature and post-hatch feeding strategy.

Colibacillosis is a poultry disease that negatively affects welfare and causes economic losses. Treatment with antibiotics raises concerns on antimicrobial resistance. Consequently, alternative approaches to enhance poultry resilience are needed. Access to feed and water directly after hatch (early feeding) may enhance resilience at later ages. Additionally, a high eggshell temperature (EST) during mid incubation may improve chick quality at hatch, supporting potential positive effects of early feeding. Effects of EST [37.8°C (control) or 38.9°C (higher)] during mid-incubation (embryo days 7-14) and feeding strategy (early feeding or 48 h delayed feeding) were tested in a 2 × 2 factorial arrangement. At hatch, Ì´ 1,800 broilers were divided over 36 pens and grown for 6 wk. At d 8 post hatch, avian pathogenic E. coli (APEC) was inoculated intratracheally as model to investigate broiler resilience against respiratory diseases. Incidence and severity of colibacillosis, local infection, and systemic infection were assessed at 6 moments between 3 h and 7 d postinoculation. Broilers were weighed daily during 13 d postinoculation and weekly thereafter. At higher EST, early feeding resulted in higher incidence of systemic infection compared to delayed feeding whereas at control EST, systemic infection was not different between feeding strategies. Regardless of EST, early compared to delayed feeding resulted in lower incidence of local infection, fewer BW deviations, and higher growth until d 35. In conclusion, early feeding could be considered as a strategy to enhance broiler resilience, but only when EST is not too high.

Irreversible lower limb ischaemia following ligation of the inferior mesenteric artery in the surgical treatment of rectal cancer.

Rectal cancer and cardiovascular disease are both commoner in the elderly and may coexist. In some severe arteriopaths the blood supply to the lower limbs may be a collateral circulation from the inferior mesenteric artery. Patients with aorto-iliac occlusion or severe stenosis may have collaterals from the inferior mesenteric artery to the lower limb blood vessels. Ligation of the inferior mesenteric artery in treating rectal cancer can result in irreversible ischaemia as outlined in this report. Routine palpation of the femoral pulses and awareness of collateral circulation may avoid the disastrous consequences seen in the two cases described.

Experience of pancreaticoduodenectomy in a district general hospital

AIMS: Long-term survival after surgery for pancreatic cancer remains very low and it is particularly important that minimal surgery-related morbidity and mortality rates are achieved. It has been stated that centres performing small numbers of proximal pancreaticoduodenectomies are likely to have high morbidity and mortality rates. The results of pancreatic surgery in a district general hospital are reported. METHODS: This was a retrospective analysis of all pancreaticoduodenectomies over 4 years. RESULTS: Twenty-one selected patients underwent proximal pancreaticoduodenectomy and two patients total pancreatectomy over a 4-year period from 1995 to 1999. The operations were performed by two surgeons with a special interest in upper gastrointestinal surgery. The median age was 62 (38-83) years. There were 14 men and nine women. Fifteen patients had adenocarcinoma of the head of the pancreas, five had ampullary carcinoma, one duodenal carcinoma and there was one case of chronic pancreatitis. Six patients had pylorus-preserving pancreaticoduodenectomy (PPPD) and 15 had a standard Whipple procedure. The median stay in hospital was 20 (13-26) days. Two patients had a pancreatic leak, one of whom developed an intra-abdominal abscess which was treated successfully by percutaneous drainage. Six patients experienced delayed gastric emptying, two of whom had PPPD. Both the 30-day and in-hospital mortality rates were zero. The median number of lymph nodes dissected was 12 and in 11 patients no nodal metastasis was found. CONCLUSIONS: It is possible to perform pancreatic surgery in a district general hospital and achieve results that are comparable to those of specialist centres.
