Module 1 Flashcards
1
Q
most common skin condition in USA
A
acne vulgaris
2
Q
Acne vulgaris has the highest incidence among individuals aged
A
12 to 25 years, with incidence peaking at 15 years of age.
3
Q
closed comedones
A
(“whiteheads”
4
Q
open comedones
A
blackheads
5
Q
Although androgen excess may lead to acne formation
A
, most individuals with acne do not overproduce androgens. However, their pilosebaceous glands are likely hypersensitive to these hormones and more prone to retention hyperkeratosis
6
Q
mild acne
A
, lesions are primarily noninflammatory comedones with occasional small papules.
face, chest, neck
7
Q
moderate acne
A
, lesions are mainly inflammatory lesions such as papules and pustules. The papules range in size from a few millimeters to one-half centimeter. The color of the acne papules in light-skinned patients ranges from light pink to bright red.
8
Q
Scarring is more likely with
A
larger and deeper pustules
9
Q
severe acne
A
severe acne, or nodulocystic acne, lesions are mainly nodules and cysts. This form of acne always results in scar formation
more common in males
10
Q
acne conglobat
A
a is severe cystic acne in which nodules, cysts, and abscesses develop; lesions are predominantly located on the trunk area instead of the face. Females with acne conglobata should be evaluated for polycystic ovary syndrome (PCOS)
11
Q
acne fulminan
A
s is rare and is seen in young adolescent males. This condition is characterized by acute onset of multiple painful, ulcerated acne lesions, along with systemic symptoms such as fever, chills, malaise, and generalized joint and muscle aches.
12
Q
rosacea
A
Rosacea, previously termed “acne rosacea,” should be ruled out. Rosacea is more common in adults and older patients and is located more centrally on the face, cheeks, chin, and nose. Comedones are never found in rosacea. There is a tendency for easy flushing in response to alcohol or heat. Telangiectasias (dilations of small groups of superficial blood vessels) may be present at the skin surface. Rosacea can be accompanied by eye complaints such as excessive dryness and irritation, and it is more common in patients of Irish, Scottish, or English descent.
13
Q
hot tub folliculitis
A
“hot tub folliculitis” (folliculitis lesions caused by Staphylococci), which appears within 1 to 4 days after hot tub use, due to insufficient temperature and inadequate chlorination of the water. Patients will complain of small red pustules that are occasionally pruritic. Folliculitis is located on the areas of the body that were immersed in the water, such as the lower torso, buttocks, and legs.
14
Q
primary goal of acne treatment
A
is to prevent and/or minimize scarring and permanent pigmentation changes

22
Q
Rosacea is characterized by flare-ups that include three cutaneous components
A
the first component is vascular in nature, with persistent erythema that primarily involves the central face
he second component is cutaneous and involves the development of recurrent acneiform, erythematous papules and pustules around the central face. The third component consists of connective tissue hyperplasia around the central face with discrete sebaceous gland hyperplasia, consisting of persistent yellow papules particularly around the nose
23
Q
rosacea tx
A
metronidazole cream, may take 6-8 weeks to work
ABX if flare (tetracycline, minocycline, doxycycline)
24
Q
Seborrheic keratosis
A
is one of the most common noncancerous skin growths seen in older adults. It is characterized by benign, warty-appearing growths that are usually found on the trunk, but they may also be seen on the hands and face. They develop in both sun-exposed and sun-protected areas
25
Seborrheic keratosis tx
does not require tx
removal if symptomatic
26
ABCDEs of malignant melanoma.
A = asymmetry
B = border irregularity
C = color change
D = diameter larger than a pencil eraser (greater than 6 mm)
E = an evolving lesion (changing over time); may also be used for elevated, as in a raised lesion
27
Actinic keratosis (AK
), also called solar keratosis and senile keratosis, is the most common precancerous skin lesion found in lighter-skinned (white) patients. They are found on sun-exposed areas of skin that have been damaged by cumulative sun exposure
rough or scaly rash
removal indicated
28
All melanomas should be tested for mutations in
BRAF, a gene involved in cell growth signaling,
29
Basal cell carcinoma
(BCC) is a malignant tumor of the skin that originates in the basal cells of the epidermis. It is a slow-growing and locally invasive tumor that rarely metastasizes. It represents the beginning of a continuum of skin cancers in both severity and mortality.
30
Squamous cell carcinoma
(SCC), a malignant tumor originating from keratinocytes, can invade the dermis and occasionally metastasize to distant sites.
31
more common of the two nonmelanomatous skin cancers and the most common type of skin cancer overall
basal cell
32
The most important risk factor for both BCC and SCC is
chronic accumulated sun exposure
33
A typical patient with nonmelanomatous skin carcinoma is an adult or elderly patient who presents with
complaints of a spot or a bump that is getting larger or a sore that is not healing. Often the lesion appears as a thick, rough patch that may bleed if scratched or scraped.
34
surgery has the highest cure rate for both BCC and SCC.
Mohs microsurgery
35
Refractory errors include
myopia, hyperopia, astigmatism, and presbyopia
36
what is responsible for central visual acuity
macula of retina, most important portion of retina for distinguishing visual details
37
Light ray convergence in front of the retina causes
myopia, or near-sightedness
38
If light rays converge posterior to the retina, the patient is
hyperopic, or farsighted.
39
if light rays focus on two separate lines rather than a single point, the patient has .
astigmatism
40
refractive error presentation
change in vision, headache
gradual onset
not typically accompanied by pain
worsened visual acuity
41
the lens of eye cannot
shed unviable cells
42
3 types of cataracts
nuclear- significant near sightedness
cortical- no significant impairment to vision
posterior- haze, severe glare in bright light, associated with steroid use, faster progression
43
Age-related cataracts tend to be
bilateral in nature and may manifest as blurred or distorted vision, with complaints of a glare when driving at night or in bright light
44
Glaucoma is defined as
a group of diseases characterized by progressive damage to the optic nerve, resulting in optic nerve atrophy and blindness, most typically associated with elevated intraocular pressure
45
most common glaucoma
open angle, is characterized as a chronic form of the disorder that, before loss of peripheral visual fields, is asymptomatic. It has an excellent prognosis if treated early and appropriately
46
angle closure glaucoma
most often associated with acute episodes of significant eye pain, redness, and acute visual loss, which, if untreated, may rapidly lead to permanent blindness.

56
leading cause of new cases of legal blindness among Americans aged 20 to 64
diabetic retinopathy
57
Almost all patients with diabetes will develop background diabetic retinopathy after they have had diabetes for at least .
20 years
58
background diabetic retinopathy fundoscopic exam
, microaneurysms, intraretinal hemorrhage, macular edema, and lipid deposits may be apparent.
59
The only pharmacologic agent that has been found to slow the progression of diabetic retinopathy is
lisinopril, an angiotensin-converting enzyme inhibitor.
60
the leading cause of blindness in patients older than 60 years
macular degeneration
61
dry macular degeneration
characterized by slow, progressive atrophy and degeneration of the retina
62
wet macular degeneration
new blood vessels develop under the retina in the macula, causing a sudden distortion or loss of central vision
63
Vision that corrects with the pinhole test implies an
uncorrected refractive error.
64
hyperthyroidism
includes a heterogeneous group of conditions characterized by the excessive secretion and synthesis of one or both of the thyroid hormones thyroxine (T4) and triiodothyronine (T3).
65
hyperthyroidism more common in
women than men (8:1)
20-40 yr olds
66
Graves' dx
by far the most common cause of spontaneous hyperthyroidism in the United States. An autoimmune disorder characterized by autoreactive, agonistic antibodies to the thyroid-stimulating hormone (TSH) receptor,
most common hyperthyroid during pregnancy
67
Subacute thyroiditis
most common cause of thyrotoxicosis
Characterized by glandular inflammation and follicular cell destruction, it is thought to be of viral etiology, frequently occurring following an acute viral infection.
68
hyperthyroid clinical presentation
anxiety, nervousness, diaphoresis, fatigue, heat intolerance, palpitations, weight loss, and insomnia. In situations in which the thyroid tissue has become enlarged, the patient may complain of fullness or pressure in the neck. Additional symptoms include weakness, exercise intolerance, tremors, lower extremity edema, weight loss in the presence of an increased appetite, menstrual irregularities, frequent bowel movements or diarrhea, and exertional dyspnea.

persistent inappropriate hypercortisolemia.
pituitary adenomas secrete excessive amounts of ACTH. The hypersecretion is random, episodic, and does not follow the usual circadian rhythm of ACTH secretion in terms of amplitude and duration
85
most frequent cause of Cushing’s syndrome,
however, is prolonged administration of exogenous glucocorticoid hormones—an iatrogenic etiology that is ACTH-independent
86

91
DM type I
a metabolic disorder characterized by severe insulin deficiency resulting from beta cell destruction, which produces hyperglycemia due to the altered metabolism of lipids, carbohydrates, and proteins.
92
immune mediated DM (type 1A)
caused by autoimmune destruction of insulin-producing pancreatic beta islet cells. The triggering factor in the development of type 1 DM is thought to be an infection or toxic insult in persons with a genetic predisposition. The most commonly identified infectious agents are congenital rubella
90% of cases
93
The classic symptoms of type 1 DM are
polyuria (increased urination), polydipsia (increased fluid intake due to excessive thirst), nocturnal enuresis, polyphagia with paradoxical weight loss (due to reduced glucose metabolism, despite increased consumption), visual changes (especially blurred vision), and eventual fatigue, weakness, and anorexia
repeated or complicated infections
94
diagnosis of DM
* Glycosylated hemoglobin (A1C) of 6.5% or higher
* Symptoms of diabetes (e.g., polyuria, polydipsia, weight loss) plus a random plasma glucose level of 200 mg/dL or higher
* Fasting plasma glucose level of 126 mg/dL or higher (following 8 hours of no caloric intake)
* Two-hour plasma glucose level of 200 mg/dL or higher during an oral glucose tolerance test (OGTT) with a 75-g glucose load
first 3- confirm with repeat testing
95
glucose level goal for DM before meals
80-130
96
glucose level goal for DM 2h after meal
180 or less
97
Optimal SMBG for patients with type 1 DM is
three to four times a day—before each meal and before bedtime
98
hypoglycemia symptoms
diaphoresis, tachycardia, hunger, shakiness, altered mentation (ranging from an inability to concentrate to frank coma), slurred speech, and seizure
<70 BS
99
appropriate foods for hypoglycemia tx
1/2 cup of fruit juice
6 oz regular soda
1 cup milk
glucose tabs
check blood sugar 15m after tx
100
Somogyi effect
, for example, is a unique combination in which a diabetic patient develops hypoglycemia during the night with rebound hyperglycemia in the morning
101
type 1 DM exercise guidelines
* Check blood glucose before, every 30 to 60 minutes during, and after exercise.
* Avoid exercise if fasting glucose is more than 250 mg/dL and ketosis is present or if the glucose level is more than 300 mg/dL, regardless of whether ketosis is present.
* Consume additional carbohydrate if the glucose level is less than 100 mg/dL and as needed to avoid hypoglycemia.
* Identify when changes in insulin dose or food intake are necessary.
102
type 2 DM
abnormal secretion of insulin, resistance to the action of insulin in the target tissues, and/or an inadequate response at the level of the insulin receptor. Type 2 DM reduces life expectancy because of complications that are affected by the duration of DM, the degree of blood glucose control, and other cardiovascular risk factors such as smoking and hypertension.
103
Type 2 DM is associated with two physiological abnormalities:
insulin resistance and impaired insulin secretion by the beta islet cells of the pancrea
104
If weight loss is indicated for type II DM
, a moderate caloric restriction of 500 to 750 calories less than the patient’s average daily intake, as calculated from a detailed food history (which can be tracked with a food diary), can be instituted.
105
DM exercise recommendations
150 min/week of moderate-intense physical exercise
at least 3 days/week
106
biguanide
metformin
works by suppressing excessive hepatic glucose production and by increasing glucose utilization in peripheral tissues
contra: kidney dx
500mg/day with meal x1 week, then bid
107
Sulfonylureas
glucotrol
work by stimulating pancreatic insulin secretion; thus, pancreatic beta cells must still be producing insulin in order for sulfonylureas to be effective, as they do not reduce insulin resistance
higher risk of hypoglycemia
lowest possible dose with once daily at breakfast
108
thiazolidinediones
actos
work by sensitizing peripheral tissues to insulin by activating the nuclear glitazone receptor (also known as peroxisome proliferator-activated receptor-γ), which lowers serum glucose levels without increasing pancreatic insulin secretion
caution if risk for fracture
109
DPP4-I
Januvia
prolong and enhance the activity of incretins, which suppresses glucagon secretion and modestly reduces A1C by 0.5% to 0.8
nasopharyngitis, abdominal pain
110
GLP1 analogues
Victoza
enhance insulin secretion in a glucose-dependent manner in response to food intake. GLP1 analogues also improve insulin sensitivity, increase beta cell mass, and decrease glucagon secretion.
111
SGLT2
Invokana
block the activity of SGLT proteins in the renal proximal tubule, thereby reducing glucose reuptake and increasing the secretion of glucose in the urine. The medication is given once daily. Patients often lose weight due to the loss of sugar through the kidney
increase risk of UTI
