Title: Review of Systems II

Review of Systems II
  • Gastrointestinal, Hepatic, Neurologic Systems,

GI System
  • Peptic Ulcer Disease
  • Inflammatory bowel disease
  • Pseudomembranous colitis

GI System
  • The Dentists must
  • Monitor patient symptoms
  • Be aware of drugs that interact with GI
    medications or aggravate the medical condition
  • Be familiar with oral patterns of medical disease

GI System
  • Peptic Ulcer Disease
  • Affects about 15 of the population
  • Occurs in patients 30-50 yrs of age
  • Etiology Aggressive factors
  • H. pylori
  • Acid hypersecretion
  • Cigarette smoking
  • Use of NSAIDS
  • Psychological physical stress

GI System
  • Peptic Ulcer Disease
  • Etiology Defensive factors
  • Mucous gel
  • Bicarbonate
  • Prostaglandins
  • Mucosal blood flow
  • Signs Symptoms
  • Epigastric pain-longstanding described as
    burning, gnawing

GI System
  • Treatment
  • Antisecretory drug in combination with
  • Dental concerns
  • Systemic antibiotics for peptic ulcer disease may
    result in fungal overgrowth (candidiasis) in the
    oral cavity
  • Vascular malformations of the lip
  • Enamel erosion (as in bulemia)

GI System Dental Management
  • Review medications for NSAIDS, oral
    anticoagulants, ASA, ETOH which can cause GI
  • If active disease refer to physician
  • Care in monitoring drug therapy
  • Avoid prescribing ASA, NSAIDS
  • Selecting an analgesic
  • Consider patient risk factors for GI bleeding
    provide lowest dose for effect

GI System Dental Management
  • Care in monitoring drug therapy
  • Acid blocking drugs (cimetidine) decrease the
    metabolism of certain dental drugs
  • Diazepam
  • Lidocaine
  • Tricyclic antidepressants
  • May require dosage adjustment

Inflammatory Bowel Disease
  • 2 Disease entities
  • Crohns Disease
  • Transmural process-affecting entire bowel wall
    may produce ulcerations at any point of the
    alimentary canal
  • Ulcerative colitis
  • Mucosal disease limited to the large intestine
    and rectum
  • Inflammatory diseases of unknown etiology

Inflammatory Bowel Disease
  • Ulcerative colitis
  • Attacks of diarrhea
  • Rectal bleeding
  • Abdominal cramps
  • Crohns Disease
  • Diarrhea
  • Abdominal pain
  • Anorexia
  • Fever, malaise
  • Arthritis
  • Weight loss

Dental Implications IBD
  • Aphthous-like lesions affect 20 of Ulcerative
    Colitis pts
  • In Crohns disease, may be atypical mucosal
    ulcerations diffuse swelling of the lips

Pseudomembranous Colitis
  • Severe fatal form of colitis due to overgrowth
    of Clostridium difficile
  • Potent enterotoxins induce colitis
  • Can be caused by broad spectrum antibiotics which
    wipe out competitive anaerobic gut bacteria

Pseudomembranous Colitis Dental concerns
  • Certain systemic antibiotics are associated w/
    risk of pseudomembranous colitis in elderly,
    debilitated patients
  • Lincomycin, clindamycin, ampicillin,
  • No reports of pseudomembranous colitis exist
    following short term use of clindamycin for AHA
    propylactic regimen

Liver Disease
  • Liver plays important role in metabolism
  • Secretion of bile - fat absorption
  • Conversion of glucose to glycogen
  • Excretion of bilirubin
  • Liver abnormalities can lead to impaired
    metabolism of
  • Amino acids, ammonia, protein, carbohydrates,
  • Liver provides synthesis of coagulation factors
    drug metabolism

Signs of Liver Disease
Jaundice Yellow skin conjunctiva
Tender, swollen liver Accumulation of fluids cirrhosis
Peripheral edema Accumulation of fluid due to blockage in the portal circulation
Ascites Accumulation of fluid in abdomen due to blocked portal circulation
Hepatic encephalopathy Confusion, coma due to accumulation of waste
Spider angiomas Arteriovenous anastomoses (face, neck, upper thorax)
Signs of Liver Disease
Palmar erythema Blotchy erythema caused by vasodilation
Bilirubinemia Impaired conjugation of bilirubin
Inc. enzyme levels ALT, AST, Alk. Phos, GGTP from damaged hepatocytes
Prolonged Prothrombin Time Insufficient coagulation factors /or vitamin K deficiency
Liver Disease
  • Alcoholic liver disease
  • Fatty infiltrate of liver
  • Alcoholic hepatitis
  • cirrhosis
  • Hepatitis
  • Inflammation of the liver from infectious or
    non-infectious process

Alcoholic liver disease
  • Due to large, chronic alcohol consumption
  • Patient likely to be malnourished, folic acid
    deficiency, B 12, anemia, decreased immune
  • Can lead to hepatic failure
  • Malnutrition
  • Weight loss
  • Protein deficiency including coagulation factors
    (bleeding tendency)
  • Impaired urea synthesis, glucose metabolism
  • Endocrine disturbances
  • Encephalopathy
  • Renal failure
  • Portal hypertension
  • jaundice

Alcoholic liver disease Systemic
complications Oral complications
  • Unexplained injuries
  • Memory deficits
  • Slurred speech
  • Spider angiomas
  • Jaundice
  • Ascites
  • Peripheral edema
  • Ecchymoses, bleeding
  • Social problems
  • POH
  • Oral neglect

  • Candidiasis
  • Gingival bleeding
  • Oral cancer
  • Petechiae, ecchymoses
  • Xerostomia
  • Parotid gland enlargmt
  • Attrition
  • bruxism

Painless enlargement of parotid
Alcoholic liver disease
  • Dental Implications
  • Liver enzyme induction CNS effects of alcohol
    can require increased amounts of local anesthetic
    or additional anxiolytic procedure be used.
  • May require additional time at appt
  • Care in using drugs that are metabolized by liver

Alcoholic liver disease
  • Dental Implications
  • Impaired gustatory function
  • Nutritional deficiencies glossitis,
    loss of tongue papillae
  • Vitamin K deficiency, bleeding problems may
    impact surgery
  • Risk for oral cancer
  • Routine soft tissue examination each 6 months

Alcoholic liver disease
  • Dental Implications Summary
  • Look for
  • Bleeding tendencies
  • Unpredictable drug metabolism of certain drugs
  • Risk or spread of infection
  • Laboratory tests that may be helpful in
    diagnosing liver disease
  • CBC differential, AST ALT, bleeding time,
    thrombin time, prothrombin time

Dental Drugs Metabolized in Liver
  • Most LA are safe in liver disease if used in
    appropriate amounts
  • Analgesics
  • Aspirin
  • Acetaminophen
  • Codeine
  • Demerol
  • Ibuprofen
  • limit dose if severe liver dx, or if bleeding
  • limit dose if severe liver dx, encephalopathy,
    or taken w/ alcohol

Dental Drugs Metabolized in Liver
  • Antibiotics
  • Ampicillin
  • Tetracycline
  • Metronidazole
  • Vancomycin
  • avoid if severe liver disease present

  • Acute viral hepatitis is most common form of
    infectious hepatitis
  • Types A, B, C, D, E
  • Viruses behave differently

Agent Transmission Carrier of cases
HAV Fecal-oral No 47
HBV Parenteral sexual, perinatal Yes 27
HCV Parenteral sexual, perinatal Yes 36,000 cases/yr
HDV Parenteral sexual, perinatal Yes 7,500 cases/yr
HEV Fecal-oral No 1-5
Hepatitis A
  • Transmission occurs by fecal contamination of
    food water
  • Sources
  • Contaminated wells, restaurants, raw shellfish
  • Occurs primarily in children and young adults
  • Mild in severity

Hepatitis B
  • Transmission is primarily by percutaneous and
    permucosal exposures
  • Transfusion of infective blood, needle sharing,
    tatooing, body piercing
  • Indirect percutaneous through small cuts in the
  • Absorption of infective serum through mucosal
    surfaces (mouth, eye)
  • Absorption of infective secretion (saliva, semen)
  • Transfer via inanimate surfaces/vectors

Hepatitis B
  • Lifetime risk is low, but certain groups are at
    higher risk
  • Dental personnel, health care workers
  • Refugees from certain countries
  • Hemodialysis patients,
  • drug users
  • Homosexual males
  • Heterosexuals with multiple partners
  • Recipients of blood transfusions
  • Can develop chronic hepatitis, hepatocellular

Hepatitis C
  • Similar to HBV in characteristics
  • 60-90 of cases involve transmission via blood
    or blood products
  • 70 90 of adults with disease become chronic
  • 25 die from the disease
  • Risk of future development of hepatocellular
  • No vaccine

Signs Symptoms of Hepatitis
  • 3 phases of acute illness
  • Prodromal
  • Abdominal pain, anorexia, nausea, vomiting,
    fatigue, myalgia, malaise, fever
  • Icteric phase
  • Jaundice, GI symptoms may increase, hepatomegaly,
  • Convalescent phase
  • Symptoms disappear, but hepatomegaly, abnormal
    liver function tests may persist
  • Recovery months

Dental Management of Hepatitis Patients
  • Id patients who are carriers HBV, HCV, HDV
    important yet difficult
  • Id who may have active disease or history
  • physician consultation
  • Treat all patients as if they are potentially
  • Use universal precautions/vaccinated

Dental Management of Hepatitis Patients
  • No dental treatment other than urgent/emergency
    care for pts with active hepatitis unless patient
    is clinically biochemically recovered
  • If surgery need evaluation of coagulation
  • Your medical history may not tell you the
    complete story

Neurologic Disease
  • Epilepsy
  • Cerebral Vascular Accident
  • Transient Ischemic Attacks
  • Headaches
  • Paralysis

  • Group of disorders with chronic, recurrent,
    paroxysmal changes in neurologic function caused
    by abnormal/spontaneous electrical activity in
    the brain.
  • May be convulsive or involve changes emotional,
    cognitive, sensory status
  • Most common in children who often outgrow them

  • Head trauma
  • Developmental abnormalities
  • Hypoglycemia
  • Neoplasm
  • Febrile illness
  • Often unknown

Signs Symptoms
  • Tonic-Clonic convulsions
  • Aura occurs in 1/3 of patients
  • Patient looses consciousness, generalized muscle
    rigidity, pupil dilation, breathing may stop,
    beating movements of head, arms, incontinence
    then muscle relaxation and return to
  • May have stupor, headache, confusion, depression

Medical Management
  • Long-term drug management
  • Phenytoin (dilantin)
  • Carbamzepine (tegretol)
  • Valproic acid
  • All elevate seizure threshold of motor cortex
  • Surgical interventions
  • Last resort tx in severe cases

Dental Management
  • First step Identify the patient
  • History and ask questions
  • Seizure history
  • Type of seizures
  • Age at onset
  • Medications
  • Frequency of physician visits
  • Degree of control
  • Frequency of seizures
  • Date of last seizure
  • Any know precipitating factors
  • Injuries

Dental Management
  • Most patients are able to be controlled w
  • History level of seizure activity may suggest
    non-compliance w drug therapy
  • Or change in condition
  • Both of which require physician consultation

Dental Management
  • Drugs used in the treatment of seizure disorders
    may have a narrow therapeutic range
  • Drugs may cause an oral side-effect gingival
    hyperplasia (42 )
  • Check drug interactions seizure tx drugs have
    important interactions
  • Be prepared to manage grand mal seizure

Gingival Hyperplasia
Dental Management
  • Be prepared to manage grand mal seizure
  • Ligated mouth prop
  • Ask the patient to inform you if have aura
  • Manage the seizure
  • Clear area
  • Turn the patient to the side to avoid aspiration
  • Do not use padded tongue blade
  • Passively restrain

Dental Management
  • After the seizure
  • Examine for traumatic injuries
  • Discontinue treatment
  • Arrange for patient transport

Cerebral Vascular Accident
  • Serious/fatal sudden interruption of oxygenated
    blood to the brain which leads to focal necrosis
    of brain tissue
  • 3rd most common cause of death in US

Cerebral Vascular Accident
  • If a patient survives it is likely that they
    would have a disability
  • 10 recover with no disability
  • 50 have mild residual disability
  • 15-30 are disabled and require special services
  • 10-20 require institutionalization
  • Return to function is unpredictable, takes place
    slowly over months

Transient Ischemic Attack
  • Reversible temporary interruption in blood supply
    to localized areas of the brain
  • May precede CVA
  • Lasts few minutes to 24 hrs
  • Patients may have muscle weakness, numbness,
    tingling of face and extremities

Dental Management of CVA Pt
  • Deferment of elective dental treatment for 6
    months post stroke
  • Risk of re-stroking (14 within one year)
  • Some patients are put on preventive anticoagulant
    therapy require monitoring of status prior to
    surgical procedures
  • Coumadin
  • Patients may also take anti-platelet drugs

Dental Management of CVA Pt
  • Short mid-morning appointments
  • Reduce stress
  • Assist in transfer
  • Dont over-estimate patients ability
  • Communications skills needed
  • Monitor BP
  • Patients have feelings of grief, loss
    depression, so think compassionately

Dental Management of CVA Pt
  • If patients have physical limitations
  • Oral hygiene may be difficult
  • Consider adjuncts for oral care
  • Electric sonic toothbrushes
  • Therapeutic gels/rinses
  • Plan restorations with ease of cleansability

Parkinsons Disease
  • Progressive neurodegenerative disease of neurons
    that produce dopamine
  • Results in motor disturbances
  • Tremor, stiffness, shuffling gait, diminished
    facial expression
  • Affects about 1 million US individuals
  • Men slightly more affected than women

Parkinsons Disease
  • Etiology unknown
  • Associated factors
  • Mutation in chromosome 4
  • Stroke
  • Brain tumor

Clinical Features of Parkinsons Dx
Dental Management
  • Primary goals
  • Minimizing adverse effects of muscle rigidity,
  • Avoiding drug interactions
  • Care to avoid falls from the dental chair due to
    orthostatic hypotension
  • Protect the airway! Due not lay patient supine
    when placing restorations

Drugs used to treat Parkinsons Dx
  • Anticholinergic Artane, Cogentin
  • Dopamine Precursor Levodopa/Carbidopa
  • Dopamine Agonist Parlodel, Permax
  • Catechol-O-methyltransferase Inhibitors
  • - Tasmar, Comtan
  • Monoamine Oxidase B Inhibitor Selegiline
  • Neurotransmitter inhibitor Amantadine

Joint Disease
Joint Disease
  • Years of wear tear, complication of chronic
    rheumatoid arthritis articular
    joint destruction
  • Joint must be replaced with synthetic materials
  • Question Are patients with prosthetic joints at
    risk for PJI (Prosthetic Joint Infections) with
    dental procedures that cause bleeding?
  • Controversy remains--- Where is the evidence?

Joint Disease
  • Literature Review 281 isolates from 6 studies
    of PJI cause by hematogenous spread
  • 66 PJI caused by staphyloccus
  • 4.9 PJI caused by viridans strep
  • 2.1 PJI caused by peptostrep
  • Vast majority of PJI are caused by wound
    infections or skin infections

Joint Disease
  • 1997 ADA/AAOS advisory statement
  • Scientific evidence does not support the need for
    antibiotic prophylaxis for dental procedures to
    prevent PJI
  • Antibiotic premedication NOT indicated for pts
    with pins, plates, screws for most patients
    with prosthetic joint replacement

Joint Disease
  • Antibiotic premedication is recommended for
  • High risk patients with prosthetic joints
  • Immunocompromised Patients
  • Rheumatoid arthritis, Systemic lupus, drug or
    radiation induced immunosuppression nursing
    home residents
  • Other patients
  • Insulin-dependent (type I) diabetics
  • First 2 yrs following joint replacement
  • Previous prosthetic joint infections
  • Malnourishment
  • Hemophilia

Recommended Regimens
  • Patients not allergic to Penicillin
  • Cephalexin, Cephadine or Amoxicillin
  • 2.0 grams orally 1 hour before dental procedure
  • Not allergic to Penicillin unable to take oral
  • Cefazolin 1m0 gram or ampicillin 2.0 grams IM or
    IV 1 hour before dental procedure

Recommended Regimens
  • Patients allergic to Penicillin
  • 600 mg Clindamycin orally 1 hour before the
    dental procedure
  • Patients allergic to penicillin unable to take
    oral mediation
  • 600 mg Clindamycin IV 1 hour before dental

Dental Considerations
  • If pt. has RA TMJ involvement occurs in 45-75
    of patients
  • Extensive dental treatment or long appointments
  • Patient may have difficulty with maintaining oral
  • Consider adjunctive aids to oral care
  • Prevention is key

Systemic Lupus Erythematosus
  • SLE (arthritis is most common manifestation)
  • Autoimmune disease of unknown etiology
  • Genetic immune abnormalities with triggers
  • Stress, infectious agents, diet, toxins, drugs,
  • Immune complexes deposited in variety of organs
    kidney, lung, brain, GI tract, lymphatics, eye

Butterfly facial rash of SLE
Dental Management of SLE
  • Physician consultation
  • Drug considerations/drug side-effects
  • Patients may have low white blood cell count
    (leukopenia) which may have infection potential,
    especially if patient is on corticosteroids or
    cytotoxic medications
  • Abnormal bleeding thrombocytopenia
  • Patients may have cardiac valvular disorders

Dental Management of SLE
  • Patients may have oral lesions, ulcerations
    resemble lichen planus or leukoplakia
  • Xerostomia, hyposalivation, dysgeusia, glossodynia
