Iodine-induced thyrotoxicosis after ingestion of kelp-containing tea

Complementary medication is en vogue and an increasing number of patients consume herbal medicine without reporting their use to physicians. We report a case of iodine-induced hyperthyroidism due to the ingestion of a kelp-containing tea. A 39-year-old woman with multinodular goiter presented with typical signs of hyperthyroidism, which was confirmed by endocrine tests. She was not exposed to iodinated radiocontrast media and did not take medications containing iodine, such as amiodarone. However, a detailed medical history revealed that she had been treated for a period of 4 weeks by a Chinese alternative practitioner with a herbal tea containing kelp because of her enlarged thyroid. The consumption of the tea was discontinued and an antithyroid drug therapy was initiated. Physicians should advise patients with underlying thyroid disease to avoid all complementary or alternative medications containing iodine.

Raised thyroid stimulating hormone associated with kelp intake in British vegan men

To explore the hypothesis that the iodine intake of vegans might be inadequate, thyroid stimulating hormone concentrations were measured in plasma samples from 101 British men, of whom 48 were vegans and 53 were omnivores. The geometric mean thyroid stimulating hormone concentration, adjusted for age and body mass index, was 47% higher in the vegans than in the omnivores (P= 0.001). Five vegans but none of the omnivores had a thyroid stimulating hormone concentration above the reference upper limit of 5 mU/1 (P=0.022). High concentrations of thyroid stimulating hormone are usually indicative of marginal iodine status, but can also result from excessive iodine intake. The three vegans with the highest values of thyroid stimulating hormone reported regular use of kelp tablets or kelp powder. None of the other vegans, and none of the omnivores, reported taking kelp. After exclusion of the three vegans who took kelp, the remaining vegans had an adjusted geometric mean thyroid stimulating hormone concentration 29% higher than that of the omnivores (P=0.012). It was concluded that use of kelp can be associated with raised thyroid stimulating hormone, and that the iodine status of vegans who do not use kelp requires further investigation.

The Effect of Sewage on Two Bioindicators at Port Stephens, New South Wales, Australia

The effect of secondary treated sewage discharged from a recently commissioned extended ocean outfall at Boulder Bay, New South Wales, Australia on two bioindicators (oysters and kelp) was examined. Sydney rock oysters, Saccostrea commercialis Iredale and Roughley, were deployed at the study outfall location and control locations for three months after which time they were retrieved and analysed for trace metal and organochlorine concentrations. This process was repeated every six months on a total of eight sampling times, three times before and five times after the commissioning of the extended ocean outfall. The abundance and recruitment of adult and juvenile kelp plants, Ecklonia radiata were also investigated. At the outfall and control locations counts were made for a total of three periods, one before and two after the commissioning of the outfall. Within each period kelp abundance was determined on three random occasions. Univariate statistics were used to test the hypothesis of an outfall effect over and above variation between the control locations. Only three organochlorines (technical chlordane and the DDT metabolites DDE and DDD) were detected in oysters across the entire sampling period. Due to the low frequency or low mean concentrations of organochlorines an impact versus control comparison was not feasible for this study. Mean concentrations of trace metals in oysters were highly variable across all sampling periods. No obvious changes in the contaminant concentrations were noticed over time. Statistical comparisons of the data collected before and after commissioning of the extended ocean outfall revealed no short-term differences in trace metal concentrations between outfall and control locations. Analysis of variance results for both adult and juvenile kelp abundance revealed no outfall effect over and above the variation found at control locations. Student Newman-Keuls tests, however, revealed a significantly higher abundance of both adult and juvenile kelp plants immediately after the commissioning of the outfall. The value of these bioindicators for detecting impacts at small secondary treated outfalls is discussed.     

海藻酸钠微球与碘化油介入栓塞治疗转移性肝癌的临床研究

目的 比较海藻酸钠微球与碘化油化疗栓塞治疗转移性肝癌的临床疗效。方法 回顾性收集分析研究2013年1月至2014年6月的在我院通过两种不同介入模式治疗的转移性肝癌患者43例,随机分为两组:海藻酸钠微球栓塞组及碘化油栓塞组。分别对两组患者治疗前及介入术后4周左右肿瘤大小的改变情况以及栓塞术后并发症发生率,术后生存率进行比较。结果 两组患者术后4周复查CT或MRI显示,海藻酸钠微球组总有效率(CR+PR)为50%,获益率(CR+PR+NC)为90%;碘化油组患者总有效率(CR+PR)为39.1%,获益率(CR+PR+NC)为82.6%;通过术后影像表现,两组患者肿瘤的大小有变化的有19人,其中KMG组10例(50%),对照组9例(39.1%)。两组比较,有统计学意义(P0.05)。随访1年结束后,海藻酸钠微球组患者术后9个月及12个月生存期分别为100%和95%,对照组为100%和91.3%,两组累积生存率差异无统计学意义(P0.05)。结论 海藻酸钠微球组介入术后复查AFP及肿瘤大小的测定,以及治疗后患者生存率均优于单纯碘化油栓塞剂的治疗效果,海藻酸钠微球经肝动脉化疗栓塞是安全、有效的一种介入治疗手段,所以具有良好的应用前景以及重要的临床使用价值。
