Introduction: Osteosarcoma is the most common primary malignant bone tumor in children. It is highly aggressive and has a poor prognosis. A late presentation modifies and makes difficult the management affecting the survival of children. We report the case of a large conventional osteosarcoma in a 13-year-old girl. Case Presentation: Adolescent girl admitted for painful swelling of the left shoulder with absolute functional impotence of the thoracic limb and severe anemia. The painful swelling was thought to have been caused by a minor trauma that had occurred six months previously. The patient’s general condition was poor, and she presented with a large, shiny, painful mass over the shoulder and upper 2/3 of the left arm, measuring 28 cm long by 28 cm wide and 57 cm in circumference, and a large fistulous axillary adenopathy. CT scan showed a tumour lesion of the left humerus with liver and lung metastases, raising suspicion of osteogenic osteosarcoma. The tumor was classified according to TNM staging: T2N1M1(a + b). Management was modified when uncontrolled bleeding developed. It consisted of an extended amputation of the left thoracic limb. Pathological analysis showed a high-grade conventional osteosarcoma. Quality improvement was obtained for thirty days, followed by the onset of dyspnea. The evolution was towards death at forty days post-operatively. Conclusion: Osteosarcoma is a highly aggressive cancer. Delayed treatment leads to a fatal outcome. Early diagnosis is one of the challenges to be met in order to improve survival.

Introduction: Intestinal obstruction is a common cause of abdominal surgery in the neonate. Diagnosis is straightforward using standard radiology, and surgical technique depends on the underlying anatomical lesion. Peritoneal dialysis (PD) is an effective, albeit invasive, therapy for neonatal renal failure. We report a case of neonatal obstruction with severe renal failure treated by PD to highlight our hospital practice and possible remedies in a context of limited resources. Case Presentation: This was a female neonate of moderate prematurity admitted on day 4 of life for management of a flat neonatal obstruction. Radiological diagnosis suggested small bowel atresia. Biological tests revealed severe renal failure with creatinine levels of 416 micromoles per liter and blood urea of 27.1 micromoles per liter. Management consisted of preoperative peritoneal dialysis for 48 hours followed by laparotomy. The intraoperative diagnosis was GROSFElD type IIIa digestive atresia. The postoperative course was favourable, transit was resumed on day 5 and the patient returned home on day 12. Progress at 3 months was satisfactory. Conclusion: neonatal intestinal obstruction with renal failure in premature infants is associated with a poor prognosis, even more so if there is a delay in treatment. Peritoneal dialysis seems to be a suitable alternative for this management in our working conditions with limited resources.

Phase evolution and magnetic properties of (Nd_o.95la_0.05)9.5-11Febal.M_2B10.5. where M=Cr, Ti, Nb, V, Mo, Zr, hf, Ta, Mn or W, melt spun ribbons have been investigated. Almost all the alloy ribbons. except for(Nd_0.95la_0.05)_9.5Fe_78M_2B_10.5(M=Mo and Mn),consist merely two magnetic phases, namely α-Fe and R_2Fe_14B, which display a better combination of _ih_c and magnetic energy product. Remanence (Br) and coercivity (i_h_c) values in the range of 8.0 to 9.1 kG and 9.5 to 18.9 kOe. respectively, can be achieved. Among compositions studied, the Ti and W-substitutions were found to be most effective in increasing the Br and i_h_c, respectively. For a fixed refractory metal substitution, namely, M=C_r, Ti or Nb, an increase in the total rare earth concentration resulted in nanocomposites of small grain sizes and a high volume fraction of the R_2Fe_14B phase, leading to an increase in the magnetic properties.

小麦剖流制粉技术(splitmilling),是将小麦研磨系统各道产出的不同粉流混合组配加工成多种面粉成品的制粉技术。这种制粉技术,对于生产原料只有一种小麦,而销售市场又存在多样专用粉需求的面粉厂,尤其具有实际应用价值。在中试制粉厂,进行了硬质红皮冬小麦的制粉试验。加工制得23种粉流,分析了每种粉流的物理和化学特性,以及面团流变特性。所有的粉流,按照适用生产面包、通心面条、蛋糕和饼干等各类食品特定要求的不同基料混合粉之常用性质,分流混合,组配成4类基质混合粉。随后,依据生产面包、通心面条、蛋糕和饼干的相应特性要求,试验4类基质混合粉各自不同的配比组合。测试各项的检测结果,运用响应面法(responsesurfacemethod)分析,并确定适用同时生产每种专用粉的最佳配比组合。最终的配比组合结果是,同时生产面包、通心面条、蛋糕和饼干4类专用粉,它们各自占产出全部面粉的百分率,分别为53.98%、23.02%、8.02%和14.98%。优化组配制得的这些专用粉,对照比较相应的商品面粉,验证了本项研究结果。
