Joel on Software

Joel on Software為Joel Spolsky的部落格,其主要的內容已出版成書,中文版為<約耳趣談軟體> 及<約耳續談軟體>,由悅知文化所出版。雖說是針對軟體產業的洞見,但對日常工作也是別有見地,尤其是在目前管理學及顧問公司當道的時代。

Parker and Palmer Score

Parker MJ, Palmer CR: A new mobility score for predicting mortality after hip fracture. J Bone Joint Surg [Br] 1993: 75-B:797-8.

Paker and Palmer score是用於評估近端股骨骨折術後一年後死亡機率的工具。

內含Mobility score 及Abbreviated mental test score兩部分,附上spreadsheet方便使用。





Mobility (Score is the total, 0 to 9):  3: No difficulty, 2: With an aid, 1: With help from another person, 0: Not at all

  • Able to get about the house
  • Able to get out of the house
  • Able to go shopping


Abbreviated mental test: 10個項目,正確得1分

  • Give the current time to the nearest hour
  • Remember an address and repeat it at the end of the test
  • State the current year
  • Name the institution to which you have been admitted

Intertrochanteric Fractures: 10 Tips to Improve Results

好文章分享:

Haidukewych GJ: Intertrochanteric Fractures: Ten Tips to Improve Results. The Journal of Bone and Joint Surgery (American). 2009;91:712-719.

Tip 1: Use the Tip-to-Apex Distance.
Tip 2: "No Lateral Wall, No Hip Screw"
  • Lateral wall指的是reverse oblique及transtrochanteric fractures
Tip 3: Know the Unstable Intertrochanteric Fracture Patterns, and Nail Them.
Tip 4: Beware of the Anterior Bow of the Femoral Shaft.
Tip 5: When Using a Trochanteric Entry Nail, Start Slightly Medial to the Exact Tip of the Greater Trochanter.
Tip 6: Do Not Ream an Unreduced Fracture.
Tip 7: Be Cautious About the Nail Insertion Trajectory, and Do Not Use a Hammer to Seat the Nail.
Tip 8: Avoid Varus Angulation fo the Proximal Fragment - Use the Relationship Between the Tip of the Trochanter and the Center of the Femoral Head.
Tip 9: When Nailing, Lock the Nail Distally if the Fracture Is Axially or Rotationally Unstable.
Tip 10: Avoid Fracture Distraction When Nailing.

統計、流病及EBM 5

CDC 的流病入門課程(pdf),可以自己慢慢地自修。

American College of Physicians (ACP)所出版的好書

    Lang TA, Secic M: How to report statistics in medicine: annotated guidelines for authors, editors, and reviewers. Second edition. 2006; Philadelphia: American College of Physicians.
  •         這本書教您如何報告醫學統計--值得擁有。缺點:未包括如何報告mixed model, GEE等較複雜方式。
    Lang的另一篇好文章:20個常見的統計錯誤
