The following statements are CORRECT regarding Helicobacter pylori gastritis EXCEPT:
• H. pylori are found in 90% of chronic gastritis
• H. pylori are usually seen as cocci in pairs
• The presence of H. pylori increases acid secretion resulting to peptic ulcer disease. Its presence also
confers increased risk of gastric cancer
• Its incidence of infection correlates with sanitation and hygiene
H. pylori are usually seen as cocci in pairs
This type of pepsinogens are present in the urine.
pepsinogen A
These FBS levels taken on two occasions are suggestive of diabetes mellitus.
- 7.0 mmol/L
- 126 mg/dL & 100mg/dL only
- 100mg/dL
- 126 mg/dL
- 100mg/dL & 7.0 mmol/L only
- Any of the above
- 7.0 mmol/L
- 126 mg/dL
By “ fasting” for FBS, it means no caloric intake for at least:
8 hours
A patient came complaining of passing out a watery, sour-smelling stool this morning He suspected it was the
milk that he drank earlier. After challenging him to drink another glass of milk, which Stool Analysis result,
using Clinitest Tablet, will most confirm his suspicion?
0.25 g/dL
The concentration of these gastrin forms quadruples following a meal, altering the results of the assay.
- mini gastrin & medium gastrin only
- big gastrin & little gastrin only
- big gastrin & medium gastrin only
- None of the above
- big gastrin & mini gastrin only
None
Which of the following features of the organism has linked H. pylori infection to gastric cancer?
- Cytotoxin-associated gene A
- Flagella
- Adhesins
- none of the above
- All of the above
- Urease
Cytotoxin-associated gene A
The Pathogenesis of this Diabetes involves destruction of B-cells of the Pancreas by the patient’s own
immune system:
choice # 1 - Type 1 Diabetes choice # 2 - Type 1.5 Diabetes choice # 3 - Type 2 Diabetes • All of the above • None of the above • choice # 1 & choice # 2 only • choice # 2 & choice # 3 only
Choices 1 and 2.
An important consequence of this condition is the accumulation of the by-product galactilol which contributes
to cataract formation:
- none of the above
- glucosemia
- fructosemia
- galactosemia
- glycogenemia
galactosemia
This does NOT lead to Fasting hypoglycemia:
- exaggerated insulin release
- insulinomas
- Neuroglycopenic decreased rate of glucose production by the liver
- All of the above
- large consumption of ethanol
- none of the above
none
During starvation, all possible pathways are utilized by the body in this order just to ensure that the level of
glucose in the circulation is within normal range:
- degradation of stored triglycerides, glycogenolysis, gluconeogenesis, proteolysis spared
- proteolysis spared, glycogenolysis, gluconeogenesis, degradation of stored triglycerides
- glycogenolysis, gluconeogenesis, degradation of stored triglycerides, proteolysis spared
- none of the above
- glycogenolysis, degradation of stored triglycerides, proteolysis spared, gluconeogenesis
glycogenolysis, gluconeogenesis, degradation of stored triglycerides, proteolysis spared
This test can be used to check gastric HCL acid secretion:
serum pepsinogen levels & gastric pH
The currently mainstay in the diagnostic testing for H. pylori include the following:
- biopsy tissue sampling
- urea breath tests
- fecal antigen detection
- CAG-A gene detection
- Serum antibodies
- fecal antigen detection & CAG-A gene detection only
- none of the above
- biopsy tissue sampling, urea breath tests & fecal antigen detection only
- all of the above
- CAG-A gene detection & Serum antibodies only
ALL
The most common causative agent for Antibiotic-associated diarrhea
Clostridium difficile
How long is the maximum glucose level usually reached after a meal?
- choice #1 - 1 hour - true
- choice #2 - 1 1/2 hours
- choice # 3 - 2 hours
Choice 1 and 2
This level of C-peptide also suggests hyperinsulinism which is characterized by severe hypoglycemia: • >9.1 ng/mL • none of the above • >1.9 ng/mL • >1.5 ng/mL • > 5.1 ng/mL
> 1.9 ng/mL
Normally, the glucose values throughout the day is
- choice #1 - 45-130 mg/dL
- choice #2 - 2.5-7.2 mmol/L
- choice #3 - 50-110mg/dl
choice #1 & choice #2 only
Trace the probable pathogenesis of Acute Pancreatitis by arranging in order the following events:
1) local fat necrosis Injuring myofibroblasts. stellate cells, & leukocytes
2) Leaky microvasculature leading to vascular insufficiency & ischemia
3) pro-inflammatory cytokines released
4) Increased obstructed intraductal pressure
5) accumulation of active lipase

Intraoperative testing for gastrin has the following benefits over serum testing:
• patients with gastrinomas cannot tolerate serum testing
• gastrin has a short half-life & a drop in its levels post-resection is indicative of cure
• All of the above
• gastrinomas can be multiple & maybe located surgically & gastrin has a short half-life & a drop in its levels
post-resection is indicative of cure only
