Survival and outcomes have improved considerably among patients with juvenile dermatomyositis (JDM) in the west. However, mortality continues to be high in the developing world. There is paucity of literature on this aspect of JDM from developing countries. We reviewed case files of all patients with JDM registered in the Pediatric Rheumatology Clinic, Advanced Pediatrics Centre at the Post Graduate Institute of Medical Education and Research, Chandigarh, during the period 1993–2013. Seventy-six children were diagnosed to have inflammatory myopathy during this period. Of these, 63 had JDM, 3 had polymyositis while 10 had an overlap syndrome. We had reported 2 deaths out of 33 (8.3 %) patients with JDM in 2004, and over the last 9 years, we have encountered five more deaths in this group, thereby accounting for a mortality rate of 11.1 % (7/63) over two decades of follow-up. In these five children now being described, the mean duration between onset of symptoms and institution of appropriate therapy was 9.2 months. Four children (80 %) had severe muscle weakness needing nasogastric tubes at the onset, three (60 %) had cutaneous ulcers and three (60 %) had superadded infections. Two children (40 %) had gastrointestinal vasculitis and one of these developed an intestinal perforation. Three patients (60 %) had progressive pulmonary disease and air leak was identified in two of them. Although the prognosis for survival in JDM has steadily improved, in our experience the disease remains a serious illness and still carries significant mortality in the context of a developing country. 相似文献

OBJECTIVE: This study was designed to evaluate iodine deficiency status in children 6-12 years in the west coast (Aegean Region) of Turkey after 5 years of mandatory iodine prophylaxis. A total of 2300 children from 72 populations (rural and urban area) were evaluated with urinary iodine excretion and thyroid volume. DESIGN: Cross-sectional, observational study designed and performed according to surveillance methods for iodine deficiency disease (IDD) prevalence recommended by WHO/UNICEF/ICCIDD. SUBJECTS: The study population consisted of 2300 school children age ranging from 6 to 12 years. The children were selected by multiple stage randomization from 91 primary schools of 76 zones (91 clusters). Information about the use of iodized salt was obtained from the families. MEASUREMENTS: Data on the following were collected: birth date, sex, weight, height, thyroid size by palpation and ultrasonography; and urinary iodine by isotope dilution analysis method. Thyroid volumes above 97th percentile according to the WHO/ICCIDD by age and body surface area (BSA) were accepted as goitre. RESULTS: Iodized salt consumption was 51.7%. The prevalence of goitre determined by palpation was 12.1% and by ultrasound based on BSA and age were 9.8% and 5.5%, respectively. Median urinary iodine was 53 (2-142) microg/l. CONCLUSION: Mild to severe degree of iodine deficiency was detected in the west coast of Turkey. 相似文献

福州市区全民食盐加碘前后甲状腺功能亢进发病率动态分析 总被引:2,自引:2,他引:2
目的 评价全民食盐加碘对甲状腺疾病的影响。方法 观察福州市某大医院1990-1999年在采取全民食盐加碘干预措施前后甲状腺功能亢进(甲亢)等甲状腺疾病的发病率变化。结果 食盐加碘当年甲亢和桥本氏病发病率分别为531.0和238.3/10万人,比加碘前每年157.7和6.0/10万人有明显上升,1997年甲亢发病率达到高峰,1998年两者发病率逐年下降,1999年下降至加碘前水平;加碘后人群甲亢和桥本氏病发病的相对危险度也呈类似的变化规律;1995年8月食盐加碘前甲亢发病率306.37/10万人就已明显高于1994年的157.7/10万人。结论 近几年甲亢和桥本氏病发病率上升的原因比较复杂,甲亢发病率本身就存在上升趋势,个别病例可能与补碘有关,且目前甲亢和桥本氏病发病率都恢复至加碘前水平,因此视有碘摄入量对人群是安全的。 相似文献

Background
Epidemiology of peptic ulcer disease (PUD) in India differs from that in the West. It may have undergone a change with recent improvement in hygiene and availability of potent antisecretory and ulcerogenic drugs. We therefore tried to assess time-trends in the frequency of PUD over the past two decades.Methods
Records of patients with uninvestigated dyspepsia and no alarm symptoms who had undergone upper gastrointestinal endoscopy at our institution during the years 1988 (n?=?2,358), 1992 (n?=?2,240), 1996 (n?=?5,261), 2000 (n?=?7,051), 2004 (n?=?5,767) and 2008 (n?=?7,539) were retrospectively reviewed. The frequencies of duodenal and gastric ulcer disease in these groups were compared.Results
Of the 30,216 patients (age:41.7±12.7 years, 34?% females) during the six study periods, 2,360 (7.8?%) had PUD. The frequencies of both duodenal ulcer and gastric ulcer showed a decline from 1988 to 2008, i.e. from 12?% to 2.9?% and 4.5?% to 2.7?%, respectively (p-value <0.001 for trend for each). The decline was more marked for duodenal ulcer, and the ratio of duodenal to gastric ulcer declined from 2.7 in 1988 to 1.1 in 2008.Conclusions
The epidemiology of PUD in India may have changed in the past two decades with the incidence of duodenal ulcer declining more rapidly than that of gastric ulcer. 相似文献16.

There is growing evidence of considerable burden of morbidity and mortality due to infectious diseases and undernutrition in school children. This study describes the nutritional status and parasitic infections of school children in two areas of rural Sri Lanka. All children in four primary schools in the Moneragala district of Sri Lanka were included in the study. The height and weight of children were measured and anthropometric indices calculated. Stool and blood samples were examined for evidence of intestinal helminthiasis, malaria and anaemia. A greater proportion of boys than girls were underweight, wasted and stunted. Over 80% of the children were anaemic but did not apparently have iron deficiency anaemia according to their blood picture. The prevalence of parasitic infections such as hookworm and Plasmodium spp that may contribute to anaemia was low. 相似文献

Several recently published investigations showed a significant improvement in the iodine supply of the German population, but so far Germany is still considered an iodine deficient country. However most of the studies presented do not meet the epidemiological criteria established by WHO, UNICEF and ICCIDD and may therefore suffer from a selection bias with respect to goiter prevalence estimates. School children, owing to their easy recruitment, representativeness of different socio-economic classes and high vulnerability of Iodine deficiency disorders (IDD), are one of the best target groups for surveillance of IDD. In this field study a total of 591 children were investigated. The total sample included 268 females and 323 males aged 7-17 years. The following data were collected: thyroid size by ultrasound, urinary iodine concentration in a first-morning spot urine, weight, height, sex and age. The median urinary iodine concentration of the children was 183 microg/L. The proportion of samples with concentrations below 100 microg/L or below 50 microg/L was 15.4% and 4.3% respectively. Urine samples with high iodine concentrations were also found amounting to 17.3%. Almost all families (97%) declared to use iodized kitchen salt and 19.6% of all children are taking regularly iodine tablets. Application of the WHO/ICCIDD thyroid volume references to the German children resulted in a goiter prevalence of 0.2%, using either age/sex-specific or body surface area (BSA)/sex-specific cut-off values. Comparison with the P97 values of the original normative data of Gutekunst and Martin-Teichert however gives a goiter prevalence of 3% as expected. The thyroid volumes of the children in our study appear comparable with those reported recently for iodine sufficient children from Switzerland and for iodine replete Berlin children and for children with sufficient iodine supply in the region of Leipzig, so that Germany probably has no longer to be considered an iodine deficient country. Our own study and the most recently published studies on iodine replete children give rise to the supposition that the WHO/ICCIDD recommended thyroid volume references are too high. 相似文献

Hepatitis due to hepatitis B virus reactivation after cytotoxic or immunosuppressive therapy is a serious cause of liver-related
morbidity and mortality. With the characterization of the underlying pathogenesis, much progress in the management of this
important clinical problem has been made in the past 2 decades. By year 2008, it is mandatory to screen for hepatitis B surface
antigen status before initiating intensive chemotherapy or immunosuppressive therapy. All those who are hepatitis B surface
antigen positive should be started on preemptive nucleos(t)ide analogues. However, there remains important issues, such as
the type and duration of nucleos(t)ide analogue therapy, which need to be understood. As not all hepatitis B surface antigen-positive
patients will suffer from HBV reactivation, it is therefore useful to identify risk factors related to HBV reactivation so
that patients will not be treated unnecessarily with nucleos(t)ide analogues. To date, a high baseline level of viral replication,
as reflected by high serum HBV DNA level, positive serum hepatitis B e antigen, and a high intrahepatic covalently closed
circular DNA level, is the most important predictor for HBV reactivation. Recently, there has been an increased awareness
of reactivation of occult hepatitis B virus, especially in hepatitis B virus endemic area, such as the Asia-Pacific region.
Careful epidemiological study will be needed to clarify the impact of occult hepatitis B infection in patients treated with
cytotoxic or immunosuppressive therapy. 相似文献
