Which of the following statement regarding cholecystitis is FALSE?The stones may lie dormant or become lodged in the cystic or common bile duct, causing pain and cholecystitis.Cholecystitis is the inflammation of the gallbladder, however if the stones block the common bile duct, it can cause pathophysiology of the liver as well, due to insufficient drainage of the bile from the liver. The stone usually developed in the gallbladder and lodged in the duct, unlikely to fill up the whole gallbladder. During an acute attack of cholecystitis, the gallbladder is oedematous and hyperaemic, and may be distended with bile or pus

A woman with a history of gallstones complains of pain in the rib cage and constant nausea. What condition is she probably suffering from? A. cirrhosis B. appendicitis C. cholecystitis D. Xerostomia

Bile is required if the fats within the digestive tract are to be fully digested. A) True B) False

True or false: Any food that gets digested has to pass through the liver, the gall bladder and the pancreasFalseTrue

Which of the following statement(s) is/are correct regarding Courvoisier's law?I. Chronic cholecystitis is generally associated with an enlarged, palpable gallbladderII. In the presence of jaundice, a palpable gallbladder should alert the examiner of the possibility of biliary obstruction secondary to carcinoma of the head of the pancreasIII. Biliary obstruction secondary to gallstones is generally associated with a (non-enlarged) fibrotic gallbladder from coexisting chronic cholecystitisIV. Billary obstruction secondary to carcinoma of the head of the pancreas will generally not result in jaundice

Kidney stones are a common ailment affecting approximately 10% of adults in the United States.  They form when solutes precipitate out of solution as crystals in the urinary tract, and they can cause severe pain in the side, back, abdomen, and groin.  Individuals who have been previously diagnosed with kidney stones have an increased probability of developing new stones relative to unaffected individuals.  Different measures may help prevent the formation of different kinds of stones, so analysis of the composition of stones that have been passed or removed can aid in preventing recurrence.  Stones can be ground into fine powders, dissolved in a small amount of solvent, and analyzed by infrared (IR) spectroscopy, as shown in Figure 1.Figure 1  Schematic of kidney stone analysis by IR spectroscopyIR analysis of kidney stones from 50 individuals revealed the percentage of stones that contain each component, shown in Table 1 along with solubility data.Table 1  Kidney Stone Composition ParametersSome studies indicate that potassium citrate, taken orally, may prevent the formation of calcium oxalate crystals, the most abundant component of kidney stones.  Oxalic acid, shown in Figure 2, is significantly more soluble than calcium oxalate.Figure 2  Structure of oxalic acid and its associated anions with increasing pHPotassium citrate alkalinizes the urine, potentially causing a decrease in oxalate solubility and the formation of more crystals.  However, potassium citrate can also react with calcium oxalate according to the unbalanced equation shown in Reaction 1:CaC2O4 + K3(C6H5O7) → Ca3(C6H5O7)2 + K2C2O4Reaction 1Calcium citrate and potassium oxalate are both hundreds of times more soluble than calcium oxalate, so the presence of citrate and potassium ions can help maintain calcium and oxalate ions in solution.  This effect may be sufficient to overcome the decreased solubility that occurs at higher pH levels.Adapted from Primiano A, Persichilli S, Gambaro G, et al.
