We report on a case of an 85-year old man with an unusual presentation of small bowel obstruction. A palpable mass on digital rectal examination was subsequently visualised endoscopically with the appearance of a haematoma. The presence of a rectal mass as a presenting sign for small bowel obstruction is highly unusual and unreported in the literature.

Myeloid sarcoma, also known as granulocytic sarcoma or chloroma is an unusual accumulation of malignant myeloid precursor cells in an extramedullary site, which disrupts the normal architecture of the involved tissue. It is known to occur more commonly in patients with acute myelogenous leukemia and less commonly in those with myelodysplastic syndrome and myeloproliferative neoplasm, such as chronic myelogenous leukemia. The most common sites of involvement include bone, skin and lymph nodes. However, rare cases have been reported in the gastrointestinal tract, genitourinary tract, or breast. Most commonly, a neoplastic extramedullary proliferation of myeloid precursors in a patient would have systemic involvement of a myeloid neoplasm, including in the bone marrow and peripheral blood. Infrequently, extramedullary disease may be the only site of involvement. It may also occur as a localized antecedent to more generalized disease or as a site of recurrence. Herein, we present the first case in the English literature of a patient presenting with an isolated site of myeloid sarcoma arising in the form of a colonic polyp which, after subsequent bone marrow biopsy, was found to be a harbinger of chronic myelogenous leukemia.

Pulverised coal injection started at BlueScope Steel’s Port Kembla blast furnaces in 2002. With significant economic advantages to reduce consumption of coking coal via increasing the quantity of pulverised coal injected to the blast furnaces, a three-dimensional numerical model of the blowpipe/tuyere/raceway has been developed. The model has been applied in various plant-specific investigations of blast parameters, and more recently in the development of alternate coal injection lance tip geometries. The designs with the highest potential for increasing coal burnout included swirl and high dispersive tip designs. The reduction in char load entering the furnace for the best performing alternate designs was due to an increase in coal dispersion compared with the conventional design. A full-scale trial of the swirl lance design was carried out at Port Kembla’s BF6 in mid-2008. The trial delivered promising results, with PCI rates maintained. This was despite unrelated changes to the coke ash content and the burden mix fed to the furnace, which would normally reduce furnace permeability.

World Journal of Cardiology 2011年第11期3卷 359-366页

AIM: To investigate the patient characteristics, relationship between the Logistic EuroSCORE (LES) and the observed outcomes in octogenarians who underwent surgical aortic valve replacement (AVR). METHODS: Two hundred and seventy three octogenarians underwent AVR between 1996 and 2008 at Bristol Royal Inf irmary. Demographics, acute outcomes,length of hospital stay and mortality were obtained. The LES was calculated to characterize the predicted operative risk. Two groups were def ined: LES ≥ 15 (n = 80) and LES < 15 (n = 193). RESULTS: In patients with LES ≥ 15, 30 d mortality was 14% (95% CI: 7%-23%) compared with 4% (95% CI: 2%-8%) in the LES < 15 group (P < 0.007). Despite the increase in number of operations from 1996 to 2008, the average LES did not change. Only 5% of patients had prior bypass surgery. The LES identifi ed a low risk quartile of patients with a very low mortality (4%, n = 8, P < 0.007) at 30 d. The overall surgical results for octogenarians were excellent. The low risk group had an excellent outcome and the high risk group had a poor outcome after surgical AVR. CONCLUSION: It may be better treated with transcatheter aortic valve implantation.
