The most common benign disorder, fibrocystic change, affects 40–50% of premenopausal women It is a unified term for several proliferative, but nonneoplastic parenchymal alterations, which are usually bilateral and multifocal (Tavassoli 1992). The histologic pattern in each case is varying and may include pure fibrocystic lesions (duct ectasia, cysts, fibrosis, adenosis, ductal epithelial proliferation), focal fibrosis, ductal and lobular epithelial hyperplasia (also atypical) and microcystic and fibrous mastopathy due to involutional change...

Overactive Bladder
by Akanksha - 2266 reads, based on 5 votes
Overactive bladder (OAB) includes symptoms of urgency, frequency and urge incontinence.
Incidence:
Approximately 55% of individuals with OAB are women and 45% are men.
The prevalence of the condition increases with advancing age.
Pathophysiology:
The prime effector of continence is the synergic relaxation of the bladder wall muscle (detrusor) and contraction of bladder neck and pelvic floor muscles.
The sympathetic nerve fibres originating from the T11 to L 2 segments of the spinal cord, which innervate smooth-muscle fibres around the bladder neck and proximal urethra, cause these fibres to contract, allowing the bladder to fill.
As the bladder fills, sensory stretch re...

COMMON PERIOPERATIVE ACQUIRED COAGULOPATHIES
by - 1540 reads, based on 1 vote
Hepatic Dysfunction: Coagulopathy w/liver disease usually multifactorial in etiology since liver synthesizes all procoagulant proteins but factor VIII & vWF. Abnormalities include thrombocytopenia, deficiencies of vitamin K-dependent & non-dependent coag factors, disseminated intravascular coagulation (DIC), & impaired clearance of activated fibrinolytic enzymes. PT most useful test in detecting coagulopathy secondary to liver disease. FFP is replacement of choice for severe hemorrhage because it contains all coag factors synthesized by liver. Vitamin K should always be given to pts w/suspected coagulopathy secondary to liver disease.

Couinaud's nomenclature
by tegs - 3463 reads, based on 2 votes
A recent question in AIPGE 2004 on this baffling term makes it a contentious topic. Lets learn a bit about it. Here is the question and the tutorial follows it:
AIPGE 2004
The Couinaud's segmental nomenclature is based on the position of the:
1. Hepatic veins and portal vein
2. Hepatic veins and biliary ducts
3. Portal vein and biliary ducts
4. Portal vein and hepatic artery
The answer is '1. Hepatic veins and portal vein' although some people can argue about option 2 also. Still the differences in opinion are open to discussion at aipge.previouspapers.com
Couinaud's nomenclature is a surgically relevant system of hepatic segmental anatomy, which defines the liver segments by t...
