SGA grades
A, B, C
SGA A

SGA B
Mild/moderately malnourished, decreased food intake, 5-10% weight loss without stabilization or gain, some symptoms, mild moderate loss of fat or muscle
SGA C
Severely malnourished, severe deficit in food/nutrient intake, >10% weight loss which is ongoing, significant symptoms, severe functional deficit
Cachexia
Underlying disorder and loss of muscle and fat with limited improvement with optimal nutrient intake
Sarcopenia
Underlying disorder (aging) and evidence of reduced muscle and strength and no or limited improvement with optimal nutrient intake
Upper border of liver can be found at the
6th ICS, percuss from nipple to this spot and listen for change from resonant lung to dull liver, keep going until dullness changes to tympanic (lower border)
Liver span
6-12cm
Percuss for the spleen
Last intercostal space, anterior axillary line
Dullness at castells point (splenomegaly)
Percuss at the last intercostal space, anterior axillary line, ask patient to take a deep breath and hold it. A change from tympanic to dull during deep inspiration is a positive sign for splenomegaly.
T4 dermatome can be palpated at the level of
The nipples
Murphys sign detects
Cholecystitis
Murphys sign is when
Pt breathes out with pressure under the right costal margin at mid clavicular line. Patient catching breath is positive
McBurneys point helps detect
Appendicitis
McBurney’s point is done by
Palpating 2/3 from umbilicus to asis, pain is +
DDx elevated serum lipase
Acute pancreatitis, PUD, gastritis, celiac, small bowel obstruction, bowel ischemia
Common causes of acute pancreatitis
Gallstones, alcohol, post ERCP
Should someone with acute pancreatitis get an ERCP
No, it can make things worse. Only considered if theres also biliary obstruction and cholangitis
Phenyleprine is a
Vasopressor
Pancreatitis with necrosis and sepsis should be treated
NOT in the OR, only supportively in the ICU. Put off de ride ent for as long as possible.
Bilious vomiting suggests
Intestinal obstruction
Clinical presentation of ileus
Slow, with N/V, lyte imbalance, a dull ache, abdo distension
Clinical presentation of small bowel obstruction
Onset sudden, N/V, lyte imbalance, pain is crampy/colicky, and there is likely abdo distention
Prolonged postoperative ileus is
The delayed return of bowel function more than 72 hours after surgery
Treatment for prolonged postoperative ileus is
Conservative with bowel rest and serial examinations, as it is typically self resolving
Terrys nails can be indicative of
Cirrhosis
Leukonychia can be indicative of
Low albumin
Discolouration of the abdomen can be a sign of
Retroperitoneal bleeding
Signs of ascites
Distension, bulging flanks
Caput medusae indicative of
Portal hypertension
Percussion of a healthy abdo sounds
Tympanic
Dullness to abdo percussion indicates
A mass, or ascites
Auscultate for abdo bruits where
Midline above the belly button
Which quadrant is the appendix in
RLQ
Structural causes of dysphagia (3)
Neoplasm, peptic stricture, mucosal web (shatzki ring)
Treatment of Schatzki ring (steakhouse syndrome)
Disruption of the ring and acid suppressive therapy
Birds beak sign is indicative of
Achalasia
Treating achalasia
Relax the LES with CCBs, nitrates, dilation, botulin injection, surgery
Reynauds, GERD, and dysphagia is likely
Scleroderma
Treating eosinophilic esophagitis
Corticosteroids and or dilatation
Drug classes for GERD (3)
Antacids, H2 blockers, PPIs
Barrett’s esophagus is
Replacement of squamous mucosa with intestinal mucosa
Barrett’s esophagus is a precursor to
Esophageal adenocarcinoma
Main cause of peptic ulcer disease is
H Pylori
H pylori mode of transmission
Fecal oral
Symptoms of Zenker diverticulum
Older patients with dysphagia, halitosis, and regurgitation of undigested food
Etiology of travellers diarrhea longer than 2 weeks
Parasitic
Leading cause of travellers diarrhea
E. coli
Greasy and prolonged travellers diarrhea
Giardia
Patients with severe Crohn’s disease are medically managed with what kind of drugs
Biologic theory, immunomodulators
The only major modifiable risk factor in Crohn’s disease is
Smoking
Abdominal X-rays demonstrating distended loops of bowel with air fluid levels
Small bowel obstruction
hepatocellular pattern of liver injury shows
Increased AST and ALT
Treating autoimmune hepatitis
Predinisone with or without azathioprine
How can you confirm the diagnosis of autoimmune hepatitis?
Positive serology or hypergammaglobulinemia
What lab changes might you see in alcoholic hepatitis?
GGT, AST, ALT. ALT/AST>2 is especially suspicious
Arrhythmic flapping tremor of the fully extended hand is called
Asterixis
Alcohol induced persisting amnestic disorder is called
Korsakoff’s psychosis
Chronic deficiency in thiamine is seen in
Alcoholism
Three meds approved by FDA to help alcoholism
Disulfiram, naltrexone, and acomprosate
Obesity starts at BMI
30
Top three anti nauseants to know and try
Prochlorperazine, dimenhydrinate, metoclopramide
Elevated triglyceride level is defined as
250mg/dL or greater
An LDL is considered elevated when higher than
130 mg/dL
All patients started on HMG-CoA inhibitors (statins) should have what measured
Plasma lipids and liver function tests
Normal total cholesterol
Equal or less than 5.2
Normal LDL
Less than 3.4
Treat hyper cholesterolemia if LDL is greater than
130
What heart sound is often heard in those with CHF?
S4 gallop
Antimitochondrial antibody has high sensitivity and specificity for
Primary biliary cholangitis (PBC)
Elevated antinuclear antibodies and anti smooth muscle antibodies with fluctuating hepatocellular injury indicates
Autoimmune hepatitis
First line treatment for autoimmune hepatitis is
Oral glucocorticoids
Medications that can cause intrahepatic cholestasis include
Macrolide antibiotics, anabolic steroids, and oral contraceptives
Diagnosing primary biliary cholangitis is confirmed with
Serum anti mitochondrial antibody titers
