you rarely see primary spontaneous pneumothorax in adult, most of adults
with spontaneous pneumo is from some sort of underlying lung disease, today
is sunday so the chance of seeing a CT surgeon today at this hour is not
very good, but i could ask them sometime this week,
from all i could remember, spontaneous pneumothorax in adults is categorized
into primary vs secondary,
in secondary SP, patients often had underlying lung disease such as
emphysema(so one of the blebs popped), previous TB |

http://en.wikipedia.org/wiki/Mutation#Causes
Four classes of mutations are (1) spontaneous mutations (molecular decay), (
2) mutations due to error prone replication by-pass of naturally occurring
DNA damage (also called error prone translesion synthesis), (3) errors
introduced during DNA repair, and (4) induced mutations caused by mutagens.

those patients would have spontaneous pneumothorax, if there is blebs he
said then it's worth to check alpha-1 antitrypsin level, also said your
husband should not go diving, mountain climbing(like skiing in colorado),
and should not travel by air,
asked a CT surgeon today, he said your husband would need repeat surgery,

高歌，现任北京航空航天大学能源动力学院动力工程及工程热物理学科一级责任教授，
航空发动机气动热力国防重点实验室副主任，长期从事动力工程、工程热物理及流体力
学领域的教学与科研工作，并在基础科研和多学科的应用技术领域取得了一系列国际领
先水平的创新性科研成果。
他在1984年发明的"沙丘驻涡火焰稳定器"，获国家发明一等奖，钱学森同志称之为"一
项长中国人志气的重要发明"。该成果广泛应用于我国多种军用航空发动机中，取得了
数以亿元计的经济效益，至今仍保有先进水平。本刊记者于今年10月采访了高歌教授，
了解到了他近期从事的一些前沿科研工作的最新进展，尤其是他对龙卷风的研究及其工
程应用价值，让人耳目一新。
高歌教授在采访中提到，传统的航空发动机技术虽然还在不停地改进提高之中，但
受到原理和材料工艺上的限制，已经逐渐逼近了性能发... 阅读全帖 |

发帖数: 106 | 50 我第一次也是5周左右自然流产 （spontaneous miscarriage)。要不是我们是有计划的
，所以测了一下，否则就以为是例假晚来了。其实有大约25％的人第一次都有过流产，

宝宝很好，没有任何问题。不过还有一点需要提的就是，如果夫妻双方都健康，没有特
