Abnormal Uterine Bleed Notes

 pathologynuggets.blogsspot.com notes on AUB.


Abnormal uterine bleeding can be either Heavy menstrual bleed or Intermenstrual bleeding.

In heavy menstrual bleeding, there is excessive or prolonged bleeding during periods. It occurs during regular menstrual cycles. 
In contrast, bleeding occurs irregularly between menstrual cycles, in intermenstrual bleeding. 

If A is one cycle and B is the next menstrual cycle, in HMB, heavy bleeding or an increased amount of bleed occurs in these regular cycles, while in intermenstrual bleeding, the bleeding occurs, in between, these cycles.
Other types of abnormal bleeding include post-coital bleed and postmenopausal bleeding.


AUB mnemonic 

One of the classification systems for AUB  is the mnemonic PALM COEIN.


Among these, PALM represents structural causes, and COEIN represents non-structural causes.

PALM stands for polyp, adenomyosis, leiomyoma, and malignancy
Similarly, COEIN stands for coagulopathy, ovulatory cause, endometrial, iatrogenic, or cause not classified. 

Based on the age group of the patient, abnormal uterine bleeding has different causes.
In premenopausal, some of the causes include foreign body, sexual abuse, precocious puberty, and sarcoma botryoid.
Similarly, in women of reproductive age, causes can be related to pregnancy. Thus, a beta HCG test is commonly ordered in these patients. 
In postmenopausal females, the most common cause of abnormal uterine bleeding is atrophic vaginitis. It occurs due to loss of estrogen after menopause, resulting in drying and atrophy of vaginal dermal tissue. In these patients, endometrial carcinoma should be ruled out with endometrial biopsy.


Review Questions:

Question 1. COEIN in the PALM COEIN system of classification of abnormal uterine bleeding represents structural causes. (True/False) ..................

Question 2. Which investigation is indicated in post-menopausal bleeding?

Question 3. What do you mean by dysmenorrhea? ...........

Video lesson on abnormal uterine bleeding:




Answers: 

1. False. PALM represents structural causes.
2. Endometrial biopsy
3. Dysmenorrhea is defined as "painful bleeding." Some of the causes of dysmenorrhea include endometriosis, adenomyosis, PID, cervical stenosis, etc.

Different types of Heart Murmurs with Sound

ⒸPathologynuggets. Notes to review for medical students, residents, and doctors  Hello! welcome to our new blog post on cardiac murmurs. In this blog post about heart murmurs, we review the most common types of heart murmurs. Murmur is the sound of blood flowing abnormally through the heart valves and most often signs of valve disorders. If you are new to the blog, don't forget to show your support by like and subscribe. Read till the end of the blog for some bonus tips! Now let's continue our review. Normal heart sounds consist of sounds S1 and S2. S1 represents closure of mitral valve and tricuspid valves at the beginning of systole. S2 represents the closure of aortic and pulmonic valves at beginning of diastole. Thus, the interval between s1 and s2 represents systole, and in this interval systolic murmurs are heard Similarly, diastolic murmurs are heard at the interval between s2 and s1. So, what are the most common types of heart murmurs? For easy understanding, we can di...

Approach to Types of Vasculitis -- Easy review notes of Large, Medium, Small vessel and other Vasculitides

  ⒸPathologynuggets. Notes to review for medical students, residents, and doctors. Vasculitides are autoimmuine disorders characterized by inflammation of blood vessels. Most of them are chronic systemic disorders that affect the multiple systems and should be considered in differential diagnoses of any multisystem illness. Vasculitis can be divided into large vessel, medium vessel or small vessel vasculitis based on the size of the vessels involved. Large Vessel Vasculitis ‌Giant cell arterities or Temporal arteritis Takayasu arterities Medium Vessel Vasculitis ‌Polyarterities Nodosa Kawasaki Disease Small Vessel Vasculitis ‌Granulomatosis with Polyangitis(GPA) ‌Microscopic polyangitis (MPA) ‌Eosinophilic Granulomatosis with Polyangitis (EGPA)               **  Small vessel vasculitides GPA, MPA and EGPA are also known as ANCA                        ...

Heart Rate Calculation : ECG interpretation quick review

 pathologynuggets.blogspot.com 2023 ECG interpretation is an important skill for any healthcare professional. How to calculate the Heart rate? Several methods can be employed to ascertain the heart rate.  One straightforward and expedient approach involves  Identifying a QRS complex aligned with a prominent vertical grid line. followed by counting the number of large squares to the subsequent QRS complex. Dividing 300 by this count provides the heart rate.  Example: In the presented ECG, there are 2 large squares between QRS complexes, resulting in a calculated heart rate of 150 beats per minute. Note: This method only works if the paper speed is set to standard i.e. 25mm/second. At the standard speed of 25mm/s,      each large square = 0.2 second     each small square = 0.04 second Similarly, this method only works if the heart rhythm is regular. You can find how to assess heart rhythm and calculate heart rate for abnormal rhythm in this ar...
