功能失调性子宫出血诊断

答案

参考答案:

(一)无排卵型功能失调性子宫出血

1.临床表现:临床最常见的症状是子宫不规则出血,特点是月经周期紊乱,经期长短不一,出血量时多时少,甚至大量出血。

2.下列检查有助诊断

①基础体温测定(BBT):为单相改变。

②B超:可见小卵泡发育,无卵泡成熟及排卵;或可见子宫内膜增厚而无器质性改变。

③诊断性刮宫:具有血,排除内膜病变的作用,须全面刮宫。

④子宫镜检查:止血后3~7日内进行。

⑤宫颈黏液结晶检查:经前见羊齿植物叶状结晶。

⑥ * * 脱落细胞涂片检查:表现为中、高度雌激素影响。

⑦激素测定:可测定血孕酮或尿孕二醇。

(二)排卵型功能失调性子宫出血不孕或早孕时流产患者,测基础体温呈双相,但基础体温高温相期小于11日;子宫内膜活检显示分泌反应落后至少2日者。这样的患者即可诊断为黄体功能不足。

临床表现为经期延长,基础体温双相型,但高温相期第6~7日后基础体温呈缓慢下降,月经第5日诊断性刮宫发现子宫内膜仍能见到呈分泌反应的内膜,且与出血期及增生期内膜并存。这样的患者可诊断为子宫内膜不规则脱落。

Climate change,pollution,overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze.India’s Ganges and Africa’s Nile.WWF said on Tuesday.At the global launch of its report “World’s Top 10 Rivers at Risk”,the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic(水生的)life.

“If these rivers die,millions will lose their livelihoods,biodiversity(生物多样性)will be destroyed on a massive scale,there will be less fresh water and agriculture,resulting in less food security,”said.Rayi Singh,secretary—general of WWF—India.The report launched ahead of “World Water Day” today,also cited the Rio Grande in the United States,the Mekong and Indus in Asia,Europe’s Danube, La Plata in South America and Australia’s Murray—Darling as in need of greater protection.

Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up.Dams have destroyed habitats and cut rivers off from their flood plains.while climate change could affect the seasonal water flows that feed them,the report said.Fish populations,the top source of protein and overall life support for hundreds of thousands of communities worldwide,are also being threatened, it found..The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization,damming and huge influxes(流入)of sediment(积淀)from land conversion.

Climate change,including higher temperatures,also means serious consequences for fishery productivity,water supply and political security in Africa’s arid Nile basin.Tributaries(支流)flowing into the Ganges are drying up because of irrigation,WWF said.
