Long-term follow-up of high-dose treatment with autologous haematopoietic progenitor cell support in 693 patients with follicular lymphoma: an EBMT registry study.

To evaluate the outcome of a large series of patients who received high-dose treatment (HDT) for follicular lymphoma (FL), 693 patients undergoing HDT (total-body irradiation (TBI)-containing regimen: 58%; autologous bone marrow (BM)/peripheral blood progenitor cells (PBPCs): 378/285 patients) were included in the study. A total of 375 patients (54%) developed recurrent lymphoma, 10-year progression-free survival (PFS) being 31%. On multivariate analysis, younger age (P=0.003) and HDT in first complete remission (CR1) (P<0.001) correlated with longer PFS. With a median follow-up of 10.3 years, 330 patients died. Ten-year overall survival (OS) from HDT was 52%. Shorter OS was associated on multivariate analysis with older age (P<0.001), chemoresistant disease (P<0.001), BM+PBPC as source of stem cells (P=0.007) and TBI-containing regimens (P=0.004). Thirty-nine patients developed secondary myelodysplastic syndrome/acute myeloid leukaemia (MDS/AML), in 34 cases having received TBI as the conditioning regimen. The 5-year non-relapse mortality (NRM) was 9%. On multivariate analysis, older age (P<0.001), refractory disease (P<0.001) and TBI (P=0.04) were associated with a higher NRM. This long follow-up study shows a plateau in the PFS curve, suggesting that a selected group of patients might be cured with HDT. On the downside, TBI-containing regimens are associated with a negative impact on survival.     

北京市社区妇女人乳头瘤病毒感染率及其对HPV和疫苗认知情况的调查分析

[目的]评估北京市社区妇女人乳头瘤病毒（HPV）的感染率;调查社区人群对HPV的认知情况以及对HPV疫苗接种的态度。[方法]采用横断面调查方法,对北京市展览路社区15￣54岁女性进行HPV认知和流行病学问卷调查,并留取了宫颈脱落细胞或会阴部标本进行HPV DNA检测。[结果]1013名女性接受了问卷调查,832例HPV DNA检测结果纳入了统计学分析。HPV总检出率为15.38%,高、低危型HPV感染率分别为13.34%和3.25%,同时感染高、低危型HPV的检出率为1.20%。1013名调查对象中有30.7%听说过HPV,其中51.78%知道HPV感染与宫颈癌有关;HPV的知晓率与年龄和教育程度有关（P〈0.05）;经过简单宣教后,75.91%愿意接种HPV疫苗。[结论]北京市社区妇女HPV现患率较高,对HPV的知晓率也较高。开展公众健康教育,提高人群的认识水平是疫苗计划获得成功的关键因素。     

Immunity to hepatitis B, poliomyelitis and measles in fully vaccinated Aboriginal and Torres Strait Island children

Objective: To determine the immunity to hepatitis B, poliomyelitis and measles in fully vaccinated Aboriginal and Torres Strait Island children in north Queensland.
Methodology: A cross-sectional survey of immunity in a sample of children; 101 fully vaccinated Aboriginal and Torres Strait Island children, with a median age of 24.5 months, from 10 communities in North Queensland participated in this study. The main outcome measures were the prevalence of adequate antibody levels against hepatitis B, poliomyelitis and measles.
Results: Only 54% (95% Cl 44–63%) of the children had adequate immunity (10 m iu/mL) to hepatitis B, and one child had been infected despite vaccination. Although all the children (95% Cl 96–100%) had adequate immunity (i.e. neutralizing antibodies at a dilution of 1:8) to poliovirus 2, only 93% (95% Cl 86–96%) and 60% (95% Cl 50–69%) had adequate immunity to polioviruses 1 and 3, respectively. Nearly all (96%; 95% Cl 90–98%) of the children had adequate immunity (i.e. detectable IgG antibody) to measles.
Conclusions: Although a relatively low proportion of the children had adequate antibody levels against hepatitis B the clinical significance of this observation is uncertain. Further studies are needed to determine whether fully vaccinated Torres Strait Island children have been adequately protected and whether they require a booster dose of hepatitis B vaccine. A substantial proportion of fully vaccinated Aboriginal and Torres Strait Island children are inadequately protected against poliomyelitis, and therefore any such child with acute flaccid paralysis should be investigated fully for poliomyelitis. Vaccinated Aboriginal and Torres Strait Island children are well protected against measles, as are other Australian children.     

Traumatic flap displacement after LASIK

CASE REPORT: We present a case of traumatic displacement of corneal flap in the superior temporal quadrant 13 days after LASIK. The flap was repositioned after gentle irrigation of BSS, cleaned the interface and then drying the flap to verify its stability. In the next day the flap was adhered, clear cornea,smooth and visual acuity without correction was 1.00. DISCUSSION: We should try immediately to reposition the flap after traumatic displacement, as in this case.     

Proliferative ischaemic retinopathy in a case of systemic lupus erythematosus and antiphospholipidic syndrome

PURPOSE/METHODS: We report a 34-year-old woman with sytemic lupus erythematosus (S.L.E.) and antiphospholipidic syndrome which presented severe ischaemic retinopathy and neovascular proliferation. RESULTS/CONCLUSIONS: We achieved no progression of the disease and stabilization of visual acuity with panphotocoagulation. We recommend periodic ophtalmologic exams because of the scarce symptomatology.
