Evaluation of prosthetic mesh closure in semiopen-abdomen patients

Abstract Background. To avoid the adverse consequences of abdominal compartment syndrome and to reduce the high mortality the celiotomy wound in patients with abdominal sepsis was closed without tension using prosthetic mesh. This produces a semiopen situation that permits staged reinterventions together with the functional reconstitution of the continuity of the abdominal wall. Material and Methods. Twenty-five patients with intra-abdominal sepsis of various causes were evaluated retrospectively to assess the results of semiopen management of the septic abdomen and reoperations on demand in severe peritonitis. All of the patients were in a state of neglected peritonitis, and had at least one failing organ system. The Mannheim Peritonitis Index (MPI) scoring system was used for stratification of abdominal sepsis. Results. The mean MPI score of 25 patients was 24, ranging 10 to 33. Eight (32%) patients were reexplored (MPI=21). There were overall 9 (36%) complications in patients with mean MPI score of 23. Six (24%) mesh-related complications (infection and enterocutaneous fistulas) developed (MPI=19). The mean MPI score of patients without complications was 24. Four (16%) patients died with index MPI score of 26 due to fulminant hepatitis, myocardial infarction, and multiple organ failure. The admission period averaged 63 days. Conclusions. In 25 critically ill patients with abdominal sepsis the mortality was lower than expected, relative to heterogeneous data from the literature; also, major complications occurred less frequently although the mean MPI score was high. The authors conclude that this approach is a reliable contribution to the complex treatment of these patients. Electronic Publication     

肠外营养与生长激素联合应用对外科大手术术后患者蛋白代谢的影响

目的观察肠外营养与生长激素联合应用对大手术术后患者蛋白代谢的影响。方法将拟实施外科大手术(四类以上手术)熏APACHE-Ⅱ评分>7分的患者30例,入院后随机分为3组熏A组穴n=10雪押肠外营养治疗与生长激素穴金磊赛增雪联合治疗组(PN+GH)鸦B组穴n=10雪押肠外营养治疗组(PN)鸦C组穴n=10雪押正常补液组。其中A组在术后第2天开始给予生长激素皮下肌注,连续7d。结果术后8d内,B、C组患者均处于负氮平衡状态,血清白蛋白与胰岛素样生长因子-Ⅰ(IGF-Ⅰ)维持较低水平,A组在术后5d机体开始恢复氮平衡,血清白蛋白与IGF-Ⅰ水平逐渐上升,A组与B、C组比较差异有显著性(P<0.05)。结论较大的外科手术打击后,单纯给予常规的肠外营养要素不能被机体有效的利用,GH能够提高机体对肠外营养要素的利用率,促进机体蛋白合成。     

The effect of alternate-day low dose prednisolone on bone age in children with steroid dependent nephrotic syndrome

Radius, ulna, short bones (RUS), carpal (CARP) bone age (BA), tibial corticodiaphyseal (C/D) ratio and trabecular aspect were assessed in 19 children with steroid dependent nephrotic syndrome and 15 age matched healthy children. Both RUS and CARP BA were significantly lower than in the controls. Trabecular aspect and tibial C/D ratio did not show any statistical significance. There was a positive correlation between HSDS and RUS BA delay (r=−0.476, p<0.05); CARP BA delay and RUS BA delay (r=0.563, p<0.01) and RUS BA and CARP BA (r=0.891, p<0.001). In conclusion, RUS and CARP BA are both retarded and positively correlated in steroid dependent nephrotic children.     

Testicular torsion: Evaluation of contralateral testicular histology

Infertility may occur in patients with unilateral testicular torsion whose contralateral testis is intact. Depending on this observation, the physicians have begun to examine the contralateral testis. In the present prospective study we aimed to examine the histopathologic alterations occurring in the contralateral testicle with time. Sixty adult male albino rats were included in the programme, and following experimental torsion the histopathologic findings, especially those in the contralateral testis, were evaluated after 4–12 weeks. Long-term and high degree torsion of the testicle led to varying degrees of deterioration in the germinal epithelium and interstitial cells of the contralateral testicle. Histopathologic alterations were reversed in 12 weeks. Tubular diameter and testicular volume also decreased in accordance with the histopathologic alteration. In our opinion, orchiectomy following torsion of one testicle will limit potential histopathologic alterations in the contralateral testicle.     

Percutaneous radiofrequency rhizotomy of lumbar spinal facets: The results of 46 cases

The results of percutaneous radiofrequency rhizotomy of lumbar spinal facets in 46 patients followed at least three months (mean 15 months) are reported and compared with those reported previously. Satisfactory pain relief three months after the procedure was achieved in 36.4 percent of patients without operations and in 41.7 percent of patients with operations other than fusion.No patient had previously undergone fusion.Treatment of low-back pain by using radio-frequency thermocoagulation of spinal facets is a simple, safe, and well-tolerated procedure. It can be used to relief of pain in spite of decreasing rates of success within the follow-up period.     

脂多糖和同型半胱氨酸对人脐静脉内皮细胞单核细胞趋化蛋白1 mRNA表达的影响

目的探讨脂多糖和同型半胱氨酸是否诱导培养的人脐静脉内皮细胞表达单核细胞趋化蛋白1(MCP-1) mRNA及其机制.方法将生长至汇合的人脐静脉内皮细胞分为对照组、脂多糖组,脂多糖+SB203580组,同型半胱氨酸组,同型半胱氨酸+SB203580组,脂多糖+同型半胱氨酸组.采用斑点杂交和RT-PCR检测其MCP-1 mRNA的表达.用免疫细胞化学法检测对照组、脂多糖组和同型半胱氨酸组P38蛋白激酶蛋白的表达.结果培养的人脐静脉内皮细胞能表达较低水平的MCP-1 mRNA.斑点杂交和RT-PCR均显示各实验组的MCP-1 mRNA明显高于对照组.免疫细胞化学显示,P38蛋白激酶蛋白在对照组的细胞核阳性表达率为9.6%,当人脐静脉内皮细胞暴露于脂多糖或同型半胱氨酸后,细胞核阳性表达率升至46.7%或57.7%.结论脂多糖和同型半胱氨酸能诱导人脐静脉内皮细胞表达单核细胞趋化蛋白1 mRNA,P38蛋白激酶可能参与了该过程.     

Osseous destruction and rupture of the extensor tendon caused by sarcoidosis of the finger.
