Mucoid presentation of acute enterocolitis in children: a hospital-based case-control study

A hospital-based case-control study was carried out to clarify the characteristics of mucoid presentation of acute enterocolitis in children. One hundred sixty-eight cases of acute mucoid enterocolitis (study population) were compared with 200 cases of watery diarrhoea and 118 cases of blood dysentery (control groups) on the basis of clinical characteristics and findings on stool examination. Study and control groups were comparable with respect to age, body weight and nutritional status. There was no significant difference in clinical characteristics (duration of diarrhoea, stool frequency, presence of vomiting, fever and dehydration) between patients suffering from mucoid enterocolitis and blood dysentery. However, watery diarrhoea patients had significantly high frequencies of vomiting (p = 0.00001) and dehydration (p     

Utilization of screening mammography: comparison of different physician specialties

Data obtained on 426 consecutive patients referred to a breast center by 122 physicians, including family practitioners, general surgeons, and other specialists, showed that the obstetricians-gynecologists referred the greatest average number of patients per physician, with more than 50% of these referrals for screening mammography. Internists referred fewer patients by nearly a factor of ten, with only one-third of these patients referred for screening mammography. Internists may be the weakest link in the utilization of screening mammography.     

Familial amyloidotic patients' experience of the disease and of liver transplantation

Liver transplantation is a new treatment for familial amyloidotic polyneuropathy (FAP). No qualitative study examining these patients' experiences of the disease and the treatment has been published. The purpose of this study was to explore and describe the experience of the disease and the liver transplantation from the FAP patient's perspective. In-depth interviews with 11 liver transplant FAP patients were performed. The process of the FAP disease and a liver transplantation was found to involve the following categories: going downhill, defence and denial, a chance of surviving, the decision — no choice, waiting powerless and uncertain, the first few steps after surgery, freed from the death sentence, still disabled, mastering up strength to recover, and the need for support and help.     

肝移植患者术后白蛋白的应用

目的:低白蛋白血症是肝移植患者的常见并发症,也是患者预后的重要影响因素。肝移植术后选择合理的白蛋白应用方案将有益于提高肝移植患者术后近远期疗效。方法:选择2000-10/2005-06于北京大学第三医院行肝移植并且随访时间大于6个月的患者80例,对治疗方案均知情同意。医院自2003年8月开始改变了肝移植术后白蛋白的输入方案:①方案改变之前患者即白蛋白输入方案未改变组(n=50),术后早期常规输入白蛋白剂量大于60g/d。②方案改变之后患者即白蛋白输入方案改变组(n=30),适当减少术后早期白蛋白输入的常规剂量至0￣20g/d。统计分析两组患者的一般情况、术后白蛋白使用情况、预后情况及住院费用。另外,对于两组中术后存在低白蛋白相关严重并发症的患者进行进一步的比较分析。结果:80例患者全部进入结果分析。①两组患者术前及术中一般情况差异无显著性意义(P>0.05)。②白蛋白输入方案改变组术后早期白蛋白的使用量及其费用/总住院费用比例显著低于白蛋白输入方案未改变组(P<0.01)。但两组患者术后第3天肝功能情况、白蛋白水平、早期并发症发生率、早期死亡率、半年生存率及呼吸机时间等情况差异均无显著性意义(P>0.05)。③两组中术后出现低白蛋白相关严重并发症患者术后第3天肝功能情况、白蛋白水平、早期死亡率、半年生存率及呼吸机应用时间等情况差异均无显著性意义(P>0.05)。结论:肝移植术后过多输入白蛋白不能改善患者预后;适当减少术后白蛋白的常规输入剂量,同时根据血白蛋白水平及并发症情况随时调整白蛋白的输入量能够减少白蛋白的用量,对患者预后因素亦无明显影响。     

Autoantibodies against bactericidal/permeability-increasing protein in patients with cystic fibrosis

Cystic fibrosis (CF), a genetic disorder, is characterized by chronic pulmonary infection/inflammation which leads to respiratory failure. The presence of anti-neutrophil cytoplasmic autoantibodies (ANCA) has previously been observed in the sera of patients with CF. In view of the known relationship of ANCA with primary vasculitis and of their putative pathogenetic role in these disorders, we studied the presence, specificity and isotype of ANCA and their clinical associations in 66 adult CF patients. None of the 66 CF samples had autoantibodies to the major ANCA antigens, proteinase 3 or myeloperoxidase. However, 60/66 (91%) CF samples contained IgG and 55/66 (83%) IgA, autoantibodies to bactericidal/permeability increasing protein (BPI), a recently characterized ANCA specificity. All the IgA anti-BPI-positive samples were also IgG anti-BPI-positive. The autoantibody specificity was confirmed by inhibition assay and immunoblotting of CF sera against a neutrophil granule preparation. Furthermore, in this cross-sectional study, anti-BPI levels were inversely correlated with the observed reductions in FEV1 and FVC (IgA anti-BPI and FEV1: r = 0.508, <it>p</it> &lt; 0.0001), and both IgG and IgA anti-BPI levels were higher in CF patients with secondary vasculitis (<it>n</it> = 6) than in those without (<it>p</it> &lt; 0.05). ANCA with specificity for BPI were present in the majority of CF sera in this study and autoimmune processes may be associated with the development of pulmonary injury in CF.
