Clinical Skills and Approaches 
An approach to Abdominal Trauma
Abdominal Trauma Abdominal trauma can be broadly classified into: Both of these have different approach of management. In case of any trauma, you need to go serially as per ATLS guidelines, i.e., the primary survey followed by the secondary survey. For quick recap, primary survey includes: Note: according to ATLS,…

Femoral Hernia : Mnemonic
Mnemonic: FEMORAL Females (4 times more common) Elderly McEvedey operation (incision above inguinal ligament – preferred in emergency intervention due to easy access to compromised bowel for any resection if required) Obstruction/incarceration/strangulation risk is higher (rigid walls of femoral ring) Richter’s hernia – most common location Above inguinal ligament –…

Gastric Acid Secretion Made Easy
Steps for gastric acid secretion by parietal cells 1. H+ and HCO3- are produced from CO2 and H2O. 2. H+ is secreted into the lumen by H+/K+ ATPase pump. 3. HCO3- moves out of the cell, across the basolateral membrane via antiport with Cl-. 4. Cl- diffuses passively into the…

Adenoma-Carcinoma Sequence in Colorectal Cancer : Mnemonic
Adenoma-carcinoma sequence is a stepwise development of normal epithelium to carcinoma due to accumulation of mutations over a number of years leading to activation of oncogenes and loss of tumor suppressor genes. One of the pathways follows adenoma–carcinoma sequence, that is, normal → adenoma → carcinoma. The other is pertaining…
