Gallstones are small, pebble-like substances that develop in the
gallbladder. The gallbladder is a small, pear-shaped sac located below
your liver in the right upper abdomen. Gallstones form when liquid
stored in the gallbladder hardens into pieces of stone-like material.
The liquid—called bile—helps the body digest fats. Bile is made in the
liver, then stored in the gallbladder until the body needs it. The
gallbladder contracts and pushes the bile into a tube—called the common
bile duct—that carries it to the small intestine, where it helps with
digestion.
Bile contains water, cholesterol, fats, bile salts, proteins, and
bilirubin—a waste product.
Bile salts break up fat, and bilirubin gives bile and stool a
yellowish-brown color. If the liquid bile contains too much cholesterol,
bile salts, or bilirubin, it can harden into gallstones.
The two types of gallstones are cholesterol stones and pigment
stones. Cholesterol stones are usually yellow-green and are made
primarily of hardened cholesterol. They account for about 80 percent of
gallstones. Pigment stones are small, dark stones made of bilirubin.
Gallstones can be as small as a grain of sand or as large as a golf
ball. The gallbladder can develop just one large stone, hundreds of tiny
stones, or a combination of the two.
Pyelonephritis
It is the inflammation of the kidney & upper urinary tract that usually results from the bacterial infection of the bladder.
Pyelonephritis can be classified in several different catagories:
-acute pyelonephritis
-chronic pyelonephritis
-xanthogranulomatous pyelonephritis

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

3. Gallstones
• Gallstone disease, or cholelithiasis, is one of the most
common surgical problems worldwide.
• Gallstones are abnormal, inorganic masses formed in the
gallbladder and, less commonly, in the common bile or
hepatic ducts
• They are a frequent cause of abdominal pain and dyspepsia
• Although gallstones can form anywhere in the biliary tree,
the most common point of origin is within the gallbladder.
4. Who is at risk for
gallstones?• Gender: Gallstones form more commonly
in women than men.
• Age: Gallstone prevalence increases with
age.
• Obesity: Obese individuals are more likely
to form gallstones than thin individuals.
• Pregnancy: Women who have been
pregnant are more likely to form
gallstones than women who have not
been pregnant. Pregnancy increases the
risk for cholesterol gallstones because
during pregnancy, bile contains more
cholesterol, and the gallbladder does not
contract normally.
5. Who is at risk for
gallstones?
• Birth control pills and hormone therapy:
The increased levels of hormones caused
by either treatment mimics pregnancy.
• Rapid weight loss: Rapid weight loss by
whatever means-very low calorie diets or
obesity surgery-causes cholesterol
gallstones in up to 50% of individuals.
Many of the gallstones will disappear
after the weight is lost, but many do not.
Moreover, until they are gone, they may
cause problems.
• Increased blood triglycerides: Gallstones
occur more frequently in individuals with
elevated blood triglyceride levels.
6. Types of
Gallstones• Mixed (80%)
• Pure cholesterol (10%)
• Pigmented (10%)
• Black stones (contain Ca
bilirubinate, a/w cirrhosis and
hemolysis)
• Brown stones (a/w biliary tract
infection)
7. Pathogenesis
•Bile = bile salts, phospholipids, cholesterol
•Also bilirubin which is conjugated before excretion
•Gallstones due to imbalance rendering cholesterol &
calcium salts insoluble
•Pathogenesis involves 3 stages:
•1. cholesterol supersaturation in bile
•2. crystal nucleation
•3. stone growth
8.
9. Definitions
Symptomatic
cholelithiasis
Wax/waning postprandial epigastric/RUQ pain due to transient
cystic duct obstruction by stone, no fever/WBC, normal LFT
Acute
cholecystitis
Acute GB inflammation due to cystic duct obstruction. Persistent
RUQ pain +/- fever, ↑WBC, ↑LFT, +Murphy’s = inspiratory arrest
Chronic
cholecystitis
Recurrent bouts of colic/acute chol’y leading to chronic
GB wall inflamm/fibrosis. No fever/WBC.
Acalculous
cholecystitis
GB inflammation due to biliary stasis(5% of time) and not
stones(95%). Seen in critically ill pts
Choledocho-
lithiasis
Gallstone in the common bile duct (primary means
originated there, secondary = from GB)
Cholangitis Infection within bile ducts usu due to obstrux of CBD. Charcot triad: RUQ
pain, jaundice, fever (seen in 70% of pts), can lead to septic shock
10. CAUSE OF GALLSTONE
•Prolonged fasting (5-10 days) can result in
the formation of biliary sludge
(microlithiasis) which resolves by itself when
feeding is reestablished - but it can lead to
biliary symptoms or gallstone formation
11. Stages and classification
I. Initial stage or “prestone”
- Viscous, nonhomogeneous bile
- Bile sludge with formation of microstones
II. Formation of stones
- Localization:
in gallbladder, in common bile duct, in hepatic ducts
- Amount: single, plural
- Composition: cholesterol, pigment, mixed
- Clinical forms: asymptomatic (latent) and manifesting or symptomatic
Pain form with typical bile colics
Dyspeptic form
Masked form
III. Stage of chronic, recurrent cholecystitis with concremental
IV. Stage of complications
12. Predisposing factors for gallstone
formation• Cholesterol and mixed stones
Demographic and genetic factors – familial disposition; hereditary aspects;
greater prevalence in Northern Europe and North America, lower – in Asia
Obesity – increased biliary secretion of cholesterol
Weight loss – mobilization of tissue cholesterol leads to increased biliary
cholesterol secretion while enterohepatic circulation of bile acids is decreased
Female sex hormones
• Estrogens stimulate hepatic lipoproteins receptors, increase uptake of dietary
cholesterol, and increase biliary cholesterol secretion
• Natural and synthetic estrogens lead to decrease bile salt secretion and
decreased conversion of cholesterol to cholesterol esters
Ileal disease or resection – malabsorbtion of bile acids leads to decreased bile
acids pool and decreased biliary secretion of bile salts
Increasing age – increased biliary secretion of cholesterol, decreased size of bile
acid pool, biliary secretion of bile salts, and gallbladder motility
13. Predisposing factors for gallstone
formationGallbladder hypomotility leading to stasis and formation of sludge
• Fasting
• Pregnancy
• Drugs: octreotide
• Prolonged parenteral nutrition
Clofibrate therapy - increased biliary secretion of cholesterol
Decreased bile acid secretion
• Primary bilary cirrhosis
• Chronic intrahepatic cholestasis
Miscellaneous
High-calorie, high-fat diet
• Pigment stones
Demographic/genetic factors: Asia, rural settings
Chronic hemolysis
Alcoholic cirrhosis
Chronic biliary tract infections, parasite infestation
Increasing age
14. Pathogenic mechanisms
• Lithogenecity of bile in form of:
• ↑Cholesterol + normal bile acids and lecithin
• ↓Bile acids + normal cholesterol and lecithin
• ↑Cholesterol + ↓bile acids + normal lecithin
High concentration of bile acids may cause aseptic inflammation of gallbladder
• Dysfuction of bile ducts and gallbladder – disturbances of gallbladder and sphincters synchronism
• Dysfunction of gallbladder
• Dysfunction of Oddi’ sphincter
• Reflux of pancreatic juice into the gallbladder with the development of enzymatic
cholecyctitis
Reasons for motor dystunction are:
Neurotic conditions which cause asynchronism
Excessive intake of fatty and fried food lead to spasm of Oddi’ and Lutkens’ sphincters
Long termed use of spasmolytics causes hypokinesia and atonia of Oddi’ sphincter that in
term lead to the reflux of duodenal contents into bile ducts
Peptic ulcer disease with localization in the bulb
• Genetic predisposition
• Occupational hazards (vibration, sedentary life)
15. Pathogenic mechanisms
• Infection:
Bacteria: Escherichia coli, Staphylococcus, Enterococcus, Klebsiella,
Clostridium, Proteus
Viruses of hepatitis
Parasite infestation in gallbladder and duodenum (amoebiasis,
opisthorchiasis, fascioliasis, clonorchiasis, lambliasis) may activate infection in
gallbladder
• The route for bile contamination:
Hematogenous from portal vein or hepatic artery
Lymphogenous
Ascending from intestine
• The source for bile contamination – all focal chronic infection (tonsillitis, sinusitis,
etc)
• Decreased immunoreactivity
16. SYNDROMES• Pain syndrome
• Dyspeptic syndrome:
• Gastric
• Intestinal
• Inflammatory syndrome (during exacerbation)
• Cholestatic syndrome (in obstruction of common bile duct)
• Dyslipidemia
• Complications:
• Cholangitis
• Mechanical obstruction of bile ducts (choledocholithiasis)
• Galbladder perforation and bile peritonitis
• Empyema of gallbladder
• Gallbladder hydrops
• Pericholecystitis
17. Complications of
cholelithiasis• The physical examination might indicate complications of
cholelithiasis.
• Passage of gallstones from the gallbladder into the common bile duct can
result in a complete or partial obstruction of the common bile duct.
• Frequently, this manifests as jaundice.
• In all races, jaundice is detected most reliably by examination of the sclera in
natural for yellow discoloration
• Pancreatitis, another complication of gallstone disease, presents with more
diffuse abdominal pain, including pain in the epigastrium and left upper
quadrant of the abdomen.
• Cholecystitis means inflammation of the gallbladder. Like biliary colic, it too is
caused by sudden obstruction of the ducts by a gallstone, usually the cystic
duct
• Cholangitis is a condition in which bile in the common, hepatic, and
intrahepatic ducts becomes infected
18. Complications of cholelithiasis
• Severe hemorrhagic pancreatitis occurs in 15% patients and carries a high
mortality rate because of multisystem organ failure.
• In a few patients, the hemorrhagic pancreatic process and retroperitoneal
bleeding induce discoloration around the umbilicus (Cullen sign) or the
flank (Grey-Turner sign).
• Charcot triad
• (right upper quadrant pain, fever, and jaundice)
• associated with common bile duct obstruction and cholangitis
• Additional symptoms:
• alterations in mental status and hypotension, indicate Raynaud
pentad, a harbinger of worsening, ascending cholangitis.
• Sharco symptoms: pain in the right upper abdomen, high fever,
jaundice.
19. Complications of
cholelithiasis• Gangrene of the gallbladder is a condition in which the inflammation
of cholecystitis cuts off the supply of blood to the gallbladder.
• Without blood, the tissues forming the wall of the gallbladder die,
and this makes the wall very weak.
• The weakness combined with infection often leads to rupture of the
gallbladder.
• The infection then may spread throughout the abdomen, though
often the rupture is confined to a small area around the gallbladder (a
confined perforation).
20. Clinical manifestation:
complaints and anamnesis
• Pain syndrome depends on the stage of the disease:
• In gallstones – biliary colic. Characterized by sudden onset of severe pain
with duration from 30 min to 5 h, subsiding gradually or rapidly, localized in
right hypochondria or epigastria, radiated in right scapula, right part of the
chest, clavicula May be precipitated by fatty food, by consumption of a large
meal following a period of prolonged fasting
• In dyskinetic stage – dull, mild pain in right hypochondria, epigastric fullness,
related to emotional stresses
• Gastric dyspeptic syndrome: nausea and vomit with bile that don’t improve
condition, heartburn, belching, bitter taste, regurgitation with bile, loss of
appetite
• Intestinal dyspeptic syndrome: steatorrhea, meteorism
• Inflammatory: fever, chills
• Cholestatic syndrome: skin etching
21. Clinical manifestation: physical
findings
•Pain syndrome:
•Superficial palpation demonstrates tenderness in
right hypochondria, muscle rigidity
•Deep palpation shows tenderness in the point of
gallbladder, positive Ortner, Murphy, frenicus, Kehr
symptoms
•Cholestasis: jaundice, skin pigmentation, xanthoma,
xanthelasma
•Inflammation: fever, skin hyperestesia in right
hypochondria and under the right scapula
22. Clinical manifestation: Laboratory
findings• For patients with uncomplicated cholelithiasis, blood work results
usually are normal.
• However, labs can detect complications of gallstone disease;
complications might alter the course of treatment.
• CBC
• chemistry panel, including electrolytes, liver enzymes, and bilirubin.
• Choledocholithiasis can manifest with only elevation of serum
alkaline phosphatase or bilirubin.
• Nearly 50% of patients with symptomatic gallstone disease will
have abnormal transaminases
• Serum lipase and amylase levels are helpful in cases of diagnostic
uncertainty or suspected concurrent pancreatitis
23. Clinical manifestation: Imaging
Studies• X-rays
• Approximately 15% of gallstones are radiopaque and can be visualized on plain x-ray.
• A porcelain gallbladder (heavily calcified) should be removed surgically because of
increased risk of gallbladder cancer.
• Other causes of abdominal pain diagnosed with the assistance of x-rays include
perforated viscus, bowel obstruction, calcific pancreatitis, and renal stones.
• Ultrasound (US) is the most sensitive and specific test for the detection of
gallstones.
• US provides information about the size of the common bile duct and hepatic
duct and the status of liver parenchyma and the pancreas.
• Thickening of the gallbladder wall and the presence of pericholecystic fluid
are radiographic signs of acute cholecystitis
• CT scanning often is used in workup of abdominal pain without specific
localizing signs or symptoms.
• CT scanning is not a first-line study for detection of gallstones because of
greater cost and the invasive nature of the test.
• When present, gallstones usually are observed on CT scan.
25. Spectrum of Gallstone
Disease
• Symptomatic cholelithiasis
can be a herald to:
• an attack of acute
cholecystitis
• or ongoing chronic
cholecystitis
• May also resolve
Cholelithiasis
Asymptomatic
cholelithiasis
Symptomatic
cholelithiasis
Chronic
calculous
cholecystitis
Acute
calculous
cholecystitis
26. Treatment•Removal of the gallbladder laparoscopic
cholecystectomy is the treatment of choice for
symptomatic gallbladder disease
•Only gallstones that cause symptoms or complications
require treatment
•There is generally no reason for prophylactic
cholecystectomy in an asymptomatic person unless
•the gallbladder is calcified
•gallstones are > 3cm in diameter
27. Laparoscopic
Cholecystectomy• MiniLap graspers used in laparoscopic cholecystectomy to grasp
dome of gallbladder and dome of infundibulum.
• Single Incision Laparoscopic Cholecystectomy
• Single Incision Laparoscopic Cholecystectomy with Two Umbilical
Trocars
• Two Port Laparoscopic Cholecystectomy
• Laparoscopic Appendectomy
• Laparoscopic Right Colectomy
• Laparoscopic Sigmoid Colectomy
• Single Incision Colectomy
• Laparoscopic Nissen
