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

Pancreatic Carcinoma Summary Notes

  ⒸPathologynuggets.blogspot.com Notes to review for medical students, residents, and doctors. Risk Factors: Diabetes mellitus, Chronic pancreatitis, Hereditary Pancreatitis, Cigarette Smoking Courvoisier Sign of Pancreatic Cancer: Pancreatic cancer has jaundice which is painless, and gallbladder is palpable below right costal margin. Trousseau Sign of Pancreatic Carcinoma: It is associated with recurrent migratory thrombophlebitis. Other findings suggestive of this cancer are: weight loss, anorexia, dull abdominal pain which is worse at night. Other important associations include new onset Diabetes Mellitus  and non-bacterial thrombotic endocarditis . Diagnosis: Imaging by Ultrasonography or CT scan is test of choice. CT Scan shows "double-duct sign". Definitive diagnosis is by biopsy and histologic examination. If these tests are inconclusive, Endoscopic ultrasound or ERCP with brushings/biopsy for histopathology can be done. Role of CA 19-9 in pancreatic cancer: It does

Diffuse Axonal Injury --- A quick review of high yield points

Diffuse axonal injury is a type of brain injury caused by trauma in cases of sudden acceleration-deceleration. It is commonly seen in cases of high-speed vehicle accidents.  Which areas of the brain are affected by this type of injury? It mostly affects the areas where brain matter density difference is maximum. Therefore, the most commonly affected areas are gray-white junctions. It affects white matter nerve fiber tracts in these regions. Clinical Findings: Although the findings can vary from insignificant to comatose state, most cases are classified as severe with a GCS score of less than 8. Symptoms include  headache,  dizziness,  nausea, vomiting,  loss of consciousness, etc File :  Compare SWI and GRE Trauma.png Source: Karen Tong Author: SBarnes CC  Attribution-Share Alike 3.0 Unported Diagnosis: Diffuse axonal injury is diagnosed clinically. The clinical findings in these patients are out of proportion to CT Imaging findings. The patient is unconscious and may even go into a ve
