Module 3 Flashcards
1
Q
Cholecystitis is
A
an acute inflammation of the gallbladder wall, which is usually the result of an impacted calculus within the cystic duct, causing inflammation proximal to the obstruction.
2
Q
Cholecystitis without gallstones, acalculous cholecystitis, is
A
a very serious disease with high morbidity and mortality rates. It usually occurs in patients who are already critically ill because of trauma, burns, surgery, or sepsis and who have had no oral intake or have been supplemented with hyperalimentation. Patients present with severe pain and tenderness in the epigastrium or right upper quadrant (RUQ) of the abdomen accompanied by nausea, vomiting, fever, and leukocytosis.
3
Q
percentage of pt with cholelithiasis that don’t require tx
A
50%
4
Q
The risk of requiring a cholecystectomy increases with
A
age as a consequence of complications secondary to the lithiasis.
5
Q
most common gallstone
A
cholesterol, account for 75%
6
Q
six Fs
A
fat, female, forty (age 40 years), flatulent, fertile, and fat-intolerant
7
Q
After age 50, the gender distribution of cholelithiasis is
A
equal.
8
Q
Pregnancy also predisposes women to cholelithiasis, presumably because of
A
the increased abdominal pressure and increased cholesterol levels during the third trimester.
9
Q
The gallbladder is of primary importance in the development of gallstones because it
A
provides an arena for bile stasis and allows time for the slow crystallization of cholesterol
10
Q
Biliary cholesterol is increased by ingestion of
A
estrogen and oral contraceptives, multiparity, and inflammatory terminal ileal disease, which decreases the bile acid pool.
11
Q
black pigment gallstones
A
Black-pigmented stones are formed within the gallbladder and are commonly associated with hemolytic diseases, cirrhosis, long-term parenteral hyperalimentation. Black-pigmented stones are more fragile and seem to crush more easily than cholesterol stones.
12
Q
brown pigmented gallstones
A
Brown pigmented stones are composed of alternating layers of calcium bilirubinate and calcium fatty acids. Chronic bacterial infections are believed to be partly responsible for the formation of brown pigmented stones because the enzymes the bacteria produce predispose the patient to this type of stone formation. Brown stones are typically found within the intrahepatic ducts and are rarely found within the gallbladder.
13

Q
The most common complications of acute cholecystitis are
A
empyema and perforation.
22
Q
Acute pancreatitis is defined as a
A
cute inflammation of the pancreas and the surrounding tissues resulting from the release of pancreatic enzymes. These enzymes cause a chemical burn in the retroperitoneal spaces, which leads to systemic toxicity.
23
Q
80% of all hospital admissions for acute pancreatitis are the result of
A
biliary tract disease (passing of a gallstone) or alcoholism
24
Q
Mild acute pancreatitis normally
A
improves within 48 to 72 hours and does not involve other organ systems. There is minimal interstitial edema, with only occasional microscopic acinar cell necrosis.
25
Severe, acute pancreatitis is often
associated with complications and multisystem organ failure. It can be a life-threatening condition, and the patient may require monitoring in the intensive care unit (ICU).
26
acute pancreatitis subjective
abrupt onset of deep epigastric pain, persists hours- days
radiate straight thru back
aggravated by coughing, lying supine, improves when seated lying forward
pt appears ill
27
acute pancreatitis objective
epigastric severe tenderness, guarding, no rigidity
decreased bowel sounds
elevated HR
low inspiratory effort
high BP
28
The diagnosis of pancreatitis is made on the basis of 3 things
the presence of abdominal pain, elevated serum amylase and/or lipase levels, and imaging findings consistent with acute pancreatitis
29
the gold standard for acute pancreatitis diagnosis is an
elevated serum amylase level (up to three times the normal value);
30
other lab abnormal acute pancreatitis
WBC btw 12-15
high Hct
decreased Ca
high CRP (esp with pancreatic necrosis)
elevated liver enzymes
31
ranson's criteria for assessing severity of pancreatitis
At admission or at time of diagnosis:
1. Age older than 55 years
2. White blood cell count greater than 16,000/mcL
3. Blood glucose greater than 200 mg/dL
4. Base deficit greater than 4 mEq/L
5. Serum lactate dehydrogenase (LDH) greater than 350 IU/L
6. Aspartate transamine (AST) greater than 250 U/L
severe if 3 met
32

33
tx severe pancreatitis
typically in ICU
fast 2-4 weeks, TPN
6-8 L/day IV
correct glucose only if over 250
34
Chronic pancreatitis is defined as
a slowly progressive inflammatory process that results in irreversible fibrosis of the pancreas with destruction and atrophy of the exocrine and endocrine glandular tissue.
35
Chronic relapsing pancreatitis is defined as
acute attacks that occur in the setting of chronic pancreatitis and are usually precipitated by a specific event such as binge drinking or the passage of a stone.
36
causes of chronic pancreatitis
alcoholism
autoimmune dx
genetic mutation
high triglycerides
severe malnutrition
37
tropical chronic pancreatitis
The tropical, or nutritional, form of chronic pancreatitis is almost exclusively found in tropical countries. In these countries, the disease begins in early childhood and results in death in early adulthood because of complications. This type of pancreatitis also involves large intraductal calculi and a high susceptibility to pancreatic cancer. Malnutrition has a significant role, but it is not the sole cause because many areas with comparable malnutrition do not have equal prevalence of the disease. Key features of tropical pancreatitis include abdominal pain, maldigestion leading to steatorrhea, and diabetes.
38
Pancreatic insufficiency can be confirmed by the
bentiromide (nitroblue tetrazolium–para-aminobenzoic acid [NBT-PABA]) test
39
Cirrhosis is result of
hepatocellular injury involving the entire liver, resulting in fibrosis, nodular regeneration, and distorted hepatic architecture. Cirrhosis is considered permanent and irreversible.
40
In the Western Hemisphere, cirrhosis is a
leading cause of death in individuals older than age 40.
41
There are three consequences of alcohol abuse:
fatty liver, alcoholic hepatitis, and alcoholic cirrhosis.
42
fatty liver
fatty liver is a reversible condition where large vacuoles of triglycerides accumulate in the hepatocytes. The accumulation of fat in the liver causes an inflammatory reaction in the liver called steatohepatitis and is a precursor of cirrhosis.
43
most common type of cirrhosis in USA
alcoholic
44
Primary biliary cirrhosis (PBC) is a
disease that almost exclusively affects women aged 40 to 60. It is an autoimmune disease that causes destruction of the intrahepatic bile ducts, resulting in cholestasis. Autoimmune disorders such as scleroderma, Raynaud’s syndrome, autoimmune thyroid disease, celiac disease, and Sjögren’s syndrome have been linked to the development of PBC.
45
Primary sclerosing cholangitis (PSC) is
most common in men aged 20 to 40 and is associated with inflammatory bowel disease (75%), as well as with the histocompatibility antigens HLA-B8, HLA-DR3, and HLA-DR4
46
other causes of cirrhosis
wilson's dx
hemochromatosis
47
Micronodular (Laennec’s) cirrhosis is
characterized by regenerative nodules that are 1 cm in diameter or less, no bigger than normal liver lobules.
normally caused by alcoholic cirrhosis
48
Macronodular cirrhosis is characterized by .
larger nodules (diameters of 5 cm), which may be multinodular with varying size nodules and may contain central veins. These nodules are surrounded by broad fibrous bands of varying thickness, which correspond to the postnecrotic type of cirrhosis associated with chronic hepatitis

64
In general, infertility is caused by one of four conditions:
the inability to produce healthy gametes (sperm or eggs);
the failure of healthy gametes to come into close physical proximity, thus preventing fertilization;
the inability of the fertilized egg to attach to the uterine lining successfully; and the inability of a woman to carry a pregnancy to term postimplantation.

If symptoms related to the luteal phase lead to economic or social dysfunction (e.g., work absenteeism, decreased work productivity, relationship problems) and have occurred for at least three consecutive cycles, a diagnosis of PMS can be made
80
PMDD diagnosis criteria
women must have experienced symptoms during most of the menstrual cycles that occurred in the preceding year, and the symptoms must have caused significant distress and interfered with usual activities and quality of life. core symptoms: mood swings, sudden sadness, anger, irritability, depressed mood, tension, and anxiety

Endometriosis is
a painful, chronic disease characterized by the presence and proliferation of abnormally located endometrial tissue, which responds to hormonal changes in the woman’s body. Abnormally located endometrial tissue has been found outside the uterus, usually in the abdomen, on the ovaries, fallopian tubes, and the ligaments that support the uterus, as well as in the area between the vagina and rectum, on the outer surface of the uterus, and in the lining of the pelvic cavity. Other sites for these endometrial growths may include the bladder, bowel, vagina, cervix, vulva, and in abdominal surgical scars. Rarely, endometrial tissue may be located in the lung, arm, thigh, brain, or other non–reproductive tract locations
