diabetes/cases Flashcards
Genetics and DM
- Type 1: 50% btw identical twins
- Type 2: 90% btw identical twins!
HLA association and DM
- Type 1: HLA-DQ/DR
- Type 2: none
Lipids in poorly controlled diabetes/insulin resistance
-HyperTGs with HDL depletion
Obesity and T2DM
- greatest RF
- increased plasma FFAs –> make muscle more insulin resistant
- FFAs increase liver production of glucose
Dx DM
any of the following:
- Two fasting glucoses > 125
- Single glucose >200 with Sx
- Increased glucose lvl on OGT
- HbA1c > 6.5%
Dawn phenomenon
-morning hyperglycemia due to nocturnal HG secretion
Somogyi effect
morning hyperglycemia due to rebound from nocturnal hypoglycemia
Workup morning hyperglycemia in DM
- check 3AM glucose
- if elevated, pt has dawn phenomenon and evening insulin should be increased
- if decreased, pt has Somogyi and evening insulin should be decreased
General Management Diabetes
- Goal HbA1c < 7
- ACEi or ARB if urine + for microalbuminuria (spot >3.5 female, >2.5 male)
- Refer to podiatry if high risk
- Statin if LDL >100
- ACEi or ARB if bp > 130/80
- Aspirin if >30yo
- Pneumococcal vaccine!
Screening in Diabetics
- HbA1c q3mos. Goal 100
- BP every visit. ACE or ARB if >130/80
microalbuminuria
- 30-300mg per 24 hrs
- spot urine Albumin/Cr >3.5 (female), >2.5 (male)
Sx of DM and pathogenesis
- Polyuria: glucose in renal tube is osmotically active
- Polydipsia: reaction to polyuria
- Fatigue: unknown
- Weight loss: anabolic effects of insulin
- Blurred vision: swelling of lens due to osmosis (glucose)
- Fungal infections: Candida likes sugar
- Distal Numbness/tingling. Mononeuropathy: microscopic vasculitis leading to axonal ischemia. Polyneuropathy: multifactorial
Glyburide, Glipizide, Glimepiride (class, MoA, Advantages, SEs)
- Sulfonylureas
- Bind to Katp on pancreas beta-cells, stimulating release of insulin.
- Effective and inexpensive.
- SEs: Hypoglycemia, weight gain
Metformin (MoA, Advantages, SEs)
- enhances glucose uptake (GLUT4) and insulin sensitivity (AMPK)–suppressing beta-ox and liver gluconeogenesis.
- May cause weight loss, does not cause hypoglycemia, reduces cardiac risk (lowers LDL)
- SEs: GI upset, lactic acidosis, metallic taste
- Contraindicated if serum creatinine >1.5!! (risk of lactic acidosis
Acarbose (MoA, Advantages, SEs)
- inhibits brush border alpha-glucosidase and pancreas alpha-amylase, reducing glucose absorption from gut
- Low risk, no significant toxicity
- SEs: GI: cramping, flatulence, diarrhea
Rosiglitazone, pioglitazone (class, MoA, Advantages, SEs)
- Thiazolinediones
- Activate PPARgamma: wide array of actions; decrease insulin resistance, inhibit VEGF, modify adipocyte differentiation, decrease some interleukins, decrease LDL synthesis
- Advantages: reduced insulin level
- SEs: hepatotoxicity (monitor LFTs!)
Exanatide, liraglutide (class, MoA, Advantages, SEs)
- Incretins (GLP-1) mimetics
- Act on pancreas to release insulin in response to meals, prevent glucagon release, promote satiety, reduce liver fat production
Pramlintide
- Amylin mimetic
- aids glucose absorption, slows gastric emptying, promotes satiety, limits glucagon

- if fail, start metformin
- if fail, add another agent
- if fail, start insulin
macrovascular complications DM
- mainly, atherosclerosis –> stroke, MI, CHF. Mechanism unknown but proably glycation of lipoproteins, increased PLT adhesion, decreased fibrinolysis
- Silent MIs common
- PVD
- macrovascular complications are what kill ppl. Unclear whether tight control prevents them (as in microvascular)
Diabetic nephropathy
- microvascular complication
- Path: Kimmelstiel-Wilson–hyaline deposition (Xmas balls) pathagnomonic. Can also have diffuse flomerular sclerosis (also in HTN) and isolated GBM thickening
- Microabluminuria/proteinuria. If occurs, must have tight glycemic control and BP control or can progress to ESRD.
- If you catch microalbuminuria early (dipstick is not sensitive enough!), can slow progression w ACEis
Diabetic retinopathy
- microvascular complication
- 75% prevalence after 20 yrs of diabetes. leading cause of blindness inUS
- nonproliferative: hemorrhages, exudates, microaneurysms, venous dilations on funduscopic exam. Usually asymptomatic until macular edema.
- Proliferative: neovascularization and scarring. Vitreal hemorrhage and retinal detachment can occur! Can lead to blindness! Tx w lazer photocoagluation
Diabetic neuropathy
- Peripheral: usually distal/symmetric (“stocking/glove”). Loss of sensation leads to ulcer formation and Charcot joints. Can have painful neuropathy (hypersensitivity to light touch) Tx with gabapentin, TCAs, pregabalin
- CN complications: 2/2 nerve infarctions. Often CNIII, IV, VI.
- Mononeuropathies: 2/2 infaction (media, ulnar, common peroneal) Lumbar plexopathy
- Autonomic neuropathy: impotence, neurogenic bladder, gastroparesis, constipation/diarrhea, postural hypotension
- Tx is complex. NSAIDs, TCAs,, gabapentin may be helpful. Metoclopramide and other promotility agents for gastroparesis
Diabetic third nerve palsy
eye pain, diplopia, ptosis, inability to adduct
-pupils are spared!
Diabetic foot
- Combination of ischemia and neuropathy
- neuropathy can mask PVD (claudication, rest pain)
- increased susceptibility to infection (cellulitis, candidiasis, pneumonia, osteomyelitis, polymicrobial ulcers)
- infected ulcers can –> osteomyelitis –> amputaiton
- Tx: regular foot care!

Reasonable weight loss goals (long and short term)
Reasonable long-term goal: A modest 5% to 10% reduction in body weight can produce significant benefits in health outcomes.
Reasonable short-term goal: Losing half a pound to a pound a week.
Pharm Tx obesity
- Orlistat: GI lipase inhibitor which decreases fat absorption, Side effects include gastrointestinal discomfort, fecal incontinence, and malabsorption of fat-soluble vitamins. Orlistat has been shown to result in modest (3-5 kg) weight loss when used in conjunction with calorie restriction and physical activity.
- Phenetermine: stimulant/appetite suppressant. Side effects include tachycardia, hypertension, restlessness, insomnia, and tremor. Because of the potential for addiction and withdrawal, phentermine is indicated only for short-term use.

Differentiating HF vs non-cardiac causes of dyspnea
Normal BNP effectively rules out CHF
Diastolic HF
- Sx of HF w/ preserved EF
- impaired LV filling
- more common in older women
Tx class II CHF
- ACEi – reduce mortality in systolic HF
- ARBs – improve mortality in systolic HF
- Digoxin – improves Sx and hospitalizations. Be careful in renal insufficiency pts
- Loop diuretics – central role. Caution in diastolic failure (worsen filling)
- BBs – central role in reducing mortality but can worsen HF initially. Don’t use in decompensated HF. titrate slowly.
- Eplerenone – improves mortality/hospitalization in Class II HF
Typical/Atypical agina chest pain

- Stress echo/Nuclear stress testing: more sensitive. Can jump to these in new-onset CHF
management of diastolic HF
- less well studied than systolic HF
- minimize fluid overload w diuretics (careful not to over-do…low preload can worsen ventricular filling.
- slow down HR (esp in Afib)

Examination for testicular torsion
- Cremasteric reflex absent sensitive but not specific
- Negative Prehn sign: pain relieved by lifting of testis (indicates epididymitis when positive.)
- Blue dot sign: with tenderness limited to upper pole of testis is suggestive of appendiceal torsion.
Hydrocele
cystic painless scrotal fluid collection
- most common cause of painless scrotal swelling
- positive transillumination
- generally asymptomatic and slow growing
varicocele
collection of dilated/tortuous veins in pampiniform plexus surround spermatic cord
- more common on left side (because left spermatic vein enters renal vein at 90 degrees)
- more common in adult men but can be seen in adolescents
- associated with infertility, but mechanisms unknown
- asymptomatic/dull ache/fullness
Testicular torsion
- testicle twists around vascular supply
- dangerous. Surgical window 4-12 hrs
- Symptoms: scrotal, inguinal, or lower abdominal pain which usually begins abruptly. The pain is severe, and the patient appears uncomfortable. It can occur several hours after vigorous physical activity or minor testicular trauma and there may be associated nausea and vomiting. There may be prior similar episodes that might suggest intermittent testicular torsion.
- Physical findings: swollen, tender scrotum and the cremasteric reflex is typically absent. Testicular torsion causes the orientation of the testis to change, causing a “transverse lie” although this may be difficult to appreciate in a very swollen and tender patient.
appendix testis torsion
- less dangerous than testicular torsion
- may be comfortable until examined (like epidydimitis)
- blue dot sign!
epididymitis
most frequent cause of sudden scrotal pain
-typically slowly progressive Sx over days
-It is caused by bacterial infection of the epididymis, typically from a urinary tract or sexually-transmitted infection.
-The patient may appear comfortable except when examined.
Severe swelling and exquisite pain are present on the involved side, often accompanied by high fever, rigors, and irritative voiding symptoms.
Patients may have had preceding symptoms suggestive of a urinary tract infection or sexually transmitted disease.
On exam, the scrotum is tender to palpation and edematous on the involved side. The cremasteric reflex is usually present, and the testis is in its normal location and position. Positive Prehn sign (pain relieved by lifting)
Causes of testicular torsion
- idiopathic
- congenital anomaly (bell clapper deformity)
- undescended testes (torsion often caused by development of a tumor)
- recent trauma/physical exercise
Dx Testicular torsion
- color doppler (faster and more available)
- Radionuclide scintography
Tx Testicular torsion
- manual detorsion. often impossible because of pain. If successful, must still do orchiopexy
- Surgical approach: testis unwound and inspected for viability. if not viable, should be removed and contralateral orchiopexy

Significant Hx features of ankle injury
A patient who seeks help immediately, and is non-weight bearing is more likely to have a severe injury than one who presents a few days after an incident and is fully weight bearing.
A history of previous ankle sprain is a common risk factor for ankle injury.
While hearing a snap or tear is diagnostically significant in an acute knee injury, it is not in an acute ankle injury.
Compartment syndrome
- life/limb threatening complication of trauma
- etiologies: fractures, crush injuries, burns, arterial injuries
- high index of suspition
- 6 P’s: Pain (esp disproportionate), Pallor, Pulselessness, Paresthesia (most reliable), Poikilothermia, paralysis
- Tx: fasciotomy decompression
DDx lateral ankle injury
- Lateral ankle sprain (most commonly anterior talofibular ligament)
- Peroneal tendon tear (esp repeat trauma)
- Fibular fracture – severe pain, deformity
- Talar dome fracture – may occur in conjunction w sprain and initial XRs may miss
- Subtalar dislocation – high energy injury involving talocalcaneal and taloavinicular joints. Pain, swelling deformity
Ankle XR per Ottowa rules
-Only indicated if Pain in the malleolar zone and either bony tenderness along the distal 6 cm of the posterior edge of either malleolus or inability to bear weight 4 steps immediately after the injury and in the emergency department.
PE ankle injury
- inversion test: laxity indicates injury of calcaneofibular ligament
- crossed leg test: Have the patient cross their legs with the injured leg resting at midcalf on the knee to detect high ankle sprains (syndesmotic injury between the tibia and fibula).
- anterior drawer test: laxity indicates anterior talofibular ligament tear
Tx ankle sprain
RICE + NSAIDs
- use semirigid support for compression
- stretching after first few days to improve ROM

- improves with supine position
lumbar spinal stenosis pain
-improves when supine
spondylolisthesis
- anterior displacement of vertebra or vertebral column in relation to vertebra below
- can occur at any age
- aching back and posterior thigh discomfort that increases with bending
Physical Exam Back Pain
- Standing: inspect curvature (bending). palpate for rope-like tension or bony tenderness. ROM: flex, extend, lateral. Gait (heel difficult –> L5 herniation. Toe difficult –> S1 herniation). Squat test (reduces stenosis pain)
- Seated: CVA tenderness, modified SLR test, Neuro exam
- Supine: Abdominal exam, Rectal exam (when alarm Sx), passive SLR, crossed leg raise, FABER test, pelvic compression, muscle atrophy
L3 herniation
decreased patellar tendon reflex, pain in lateral thigh and medial femoral condyle. trouble with extension of quads
L4 herniation
trouble dorsiflexing ankles and walking on heels
L5 herniation
decreased medial hamstring reflex, pain in lateral leg and dorum of foot, trouble with dorsiflextion of great toe and heel walk

gout vs pseudogout
gout = negative birefringence
psuedogout = positive birefringence
psuedogout is deposition of calcium pyrophosphate dihydrate crystals. most common in knee
Lachman’s test
analogous to ant drawer test. assesses stability of ACL
psoriatic arthritis
usually oligoarthritis or polyarthritis
-associated with psoriatic plaques. Must have psoriasis to make the diagnosis, but the arthritis can appear before lesions
First line choice for mild- to moderate- OA pain
- acetaminophen
- 2nd line: NSAIDs
steroid injections for OA
should be considered if there is knee inflammation
- no more than 3 per year
- long acting triamcinolone is preferred
most common SE of opiods
constipation
pain referred to shoulder
MI
lung cancer
cholecystitits
ruptured ectopic
Restricted active and passive movement on exam
more likely to be joint problem.
Adhesive capsulitis
common in pts with metabolic disease (diabetes, hypothyroid). contraction of joint capsule
rotator cuff tendinopathy exam
Positive Apley’s Scratch test leads one towards this diagnosis, but is not definitive.
Weakness and pain with empty can testing strongly suggests supraspinatus (i.e., rotator cuff) pathology. Whether this pathology is tendonitis or a tear is often a matter of degree.
Limited active ROM due to pain supports this diagnosis.
rotator cuff tear exam
Limited ROM with significant pain is a hallmark of the physical exam in the patient with a partial or complete rotator cuff tear. In a complete tear, the patient will likely not be able to raise his arm above his head.
significant weakness with strength testing on examination that would be present with any significant tear.
Young athletes tend to present with traumatic torn rotator cuff, whereas older people present with insidious onset because of the degenerative process that occurs.
biliary colic vs cholecystitis
Pathophysiology similar, but in cholecystitis, obstructing stone does not dislodge from cystic duct outlet. Pain is more severe and unremitting.
Fever and white count in cholecystitis.
Rare signs for acute pancreatitis
Grey-Turner’s sign: ecchymotic discoloration in the flank
• Cullen’s sign: ecchymotic discoloration in the periumbilical region

- TCAs (not FDA approved. Also work for fibromyalgia and tension HAs. contraindicated in conduction defects, MAOI)
- CCB (Verapamil) – not FDA approved. Contraindicated in AV Block)
Approach to chronic pain Tx
Set clear goals with patients. Rarely possible to completely relieve pain, so aim to achieve a level of pain the patient feels he/she can live with. Measure with functional goals and numeric assessment of pain level.
Use non-pharmacologic treatments such as biofeedback for chronic pelvic pain, physical therapy and cognitive behavioral therapy for chronic back pain.
When using medications, first select specifically targeted non-opiate therapies such as anti-epileptic drugs for neuropathic pain or anti-inflammatories for musculoskeletal pain.
When using opiates:
Use long-acting agents along with the other agents and use the lowest possible dose that improves patients’ function.
Use a pain medication agreement.
Criteria for controlled HAs
- fewer than two per week or eight per month
- relieved with lifestyle modification and acute Tx medicine
