  a.htm
• Pingueculae are yellowish, slightly raised
  lesions that form on the surface of the white
  part of your eye (sclera) close to the edge of
  the cornea. They are typically found in the open
  space between your eyelids (palpebral fissure),
  which also happens to be the area exposed to the
  sun
• Pterygia are wedge- or wing-shaped growths of
  benign fibrous tissue with blood vessels
  (fibrovascular), typically located on the surface
  of the sclera. In extreme cases, pterygia may
  grow onto the eye's cornea and interfere with
  vision.

EARS

• Otitis Externa- a painful inflammation of the
  membranous lining of the auditory canal and/or
  contiguous structures.
• Refers to acute and chronic inflammatory process
• It may be diffuse or localized
• Is largely benign and self-limiting
• Invasive otitis externa is potentially life
  threatening
• Malignant OE-- now know as Necrotizing OE

4
EARS

• OE continued
• Epidemiology
• 2-3 of family practice office visit
• 10-20 more common in the summer months
• Patho- inflammation is most commonly caused by
  microbial infection. Colonization of the
  external ear is prevented immune and anatomic
  mechanisms

5
EARS

• OE patho continued
• Squamous epithelia of the canal constantly
  slough, while hair follicles sweep laterally,
  cleaning and act as a barrier. The canal
  maintains an acidic pH and repels moisture and
  the presence of normal flora inhibit the
  overgrowth of virulent bacteria. If any of this
  is broken compromised there may be colonization
  by bacteria

6
EARS

• OE patho continued
• Bacteria
• Pseudomonas aeruginosa is most common of diffuse
  infections and most cases of invasive OE
• Staphylococcus aureus typically causes a
  localized infection from a hair follicle
• Streptococcus pyogenes associated with local
  infection presenting as folliculitis
• Polymicrobial infection found in up to 1/3 of
  cases of diffuse disease

7
EARS

• OE patho continued
• Other causes of OE
• Fungal agents
• Aspergillus niger- usually local infection, but
  can cause invasive infection
• Pityrosporum
• Candida albicans
• Hyperkeratotic processes
• Eczema, psoriasis, seborrheic, or contact
  dermatitis

8
EARS

• OE
• Necrotizing Otis externa is the most severe
  infectious form of OE
• Bacterial infection extends from the skin of
  canal into soft tissue or bone
• Cranial nerves may be involved
• Pseudomonas is most common
• May have bad outcomes!

9
EAR

• OE
• Presenting complaints
• severe ear pain (otalgia) of sudden or acute
  onset
• Pain worse at night
• Worse with pulling on the pinna or earlobe or
  pushing on tragus
• Severe cases- pain with chewing
• May have purulent discharge may be noted
• Chronic OM
• May present with dryness and itching

10
EAR

• OE
• Physical findings
• Tenderness with palpation
• Otoscopic exam- canal appears swollen and red
  with drainage with bacterial infections
• Diffuse cases present with complete involvement
• Localized cases present with focal lesion
• Pseudomonas produces a copious green exudate
• Staphylococcal produces yellow crusting in
  purulent exudate
• Fungal infections presents as a fluffy, white or
  black malodorous growth
• Except in invasive disease there is no
  lymphadenopathy
• TMJ pain indicates invasive disease

11
EAR

• OE
• Diagnostic testing
• Rarely needed
• Cultures may be done of discharge if indicated in
  healthy patients
• CT or MRI may be needed if suspect invasive
  disease

12
EARS

• Dental disease
• Trigeminal or glossopharyngeal neuralgia
• Parotitis
• Impetigo
• Herpes zoster

13
EARS

• Management and Treatments of OE
• Pain meds
• Heat or ice
• Keep dry- no swimming ECT for 7 days
• Treatment for basic OE
• Irrigation if indicated
• Pain drops
• Antibiotic drops
• Ciprodex, Floxin Cortisporin
• Do not use neomycin-known to cause skin reactions
  and ototoxicity
• May need a wick if very swollen

14
EARS

• Otitis media with effusion OME involves the
  transudation of plasma from middle ear blood
  vessels leading to chronic fluid this can be
  chronic
• Acute Otitis Media-AOM is infection in the middle
  ear

15
EARS

• OM (both acute and with effusion)
• Epidemiology
• Accounts for 2-3 of all family practice office
  visits. Number of visits increases in the
  winter. More common in colder weather and in
  children.
• Contributing factors include allergies,
  rhinitis, pharyngitis due to swelling of upper
  airway membranes. Most common factor is upper
  airway infections (colds), caused by many
  different viruses.
• Influenza, RSV, pneumovirus, adenovirus

16
EARS

• AOM
• Patho-bacterial infection (or viral) by
  nasopharyngeal microorganisms follows eustachian
  tube dysfunction in which the isthmus becomes
  obstructed. Inflammation results in response to
  the bacterial products such as endotoxins,
  creating infection behind the tympanic membrane
  in the middle ear

17
EARS

• Patho continued for AOM in adults
• Streptococcus most common
• Haemophilus influenzae second most common
• Moraxella catarrhalis- third
• Viral up to 50
• Staphylococcus aureus- less common
• Streptococcus pyogenes- less common
• Mycoplasma rare
• Chlamydia pneumoniae- rare

18
EARS

• OME
• Patho- caused by collection of plasma fluid from
  engorged blood vessels resulting from the loss of
  Eustachian tube patency, either from swelling of
  the lining or direct blockage, may reflect part
  of the natural history of a resolved AOM
• Pathogens
• Streptococcus pneumoniae, haemophilus influenzae,
  Moraxella catarrhalis are most common. Less
  common are streptococcus pyogenes and aureus
• Up to ½ are viral

19

  therapeutics lectures on OM

20
EARS

• AOM- symptoms
• Deep pain, fever, sometimes decreased hearing,
  discharge with a perf, sometimes dizziness or
  ringing in the ear
• Recurrent AOM means there is clearing of the
  infection between episodes
• Chronic OME- presents with history of repeated
  bouts of AOM followed by effusion with hearing
  loss being the biggest concern

21
EARS

• Objective findings
• OME- mucous membranes of nose and mouth
  red/swollen, with recent history of URI. TM may
  be dull, may see fluid bubbles
• AOM- yellow-orange, maybe fiery red and bulging
  with an area of yellow noted. Bone landmarks and
  cone of light are not seen. Grayish/white
  collection of tissue on or behind the TM may be a
  cholesteatoma. There may be adenopathy of the
  preauricular and/posterior cervical. With an
  infected ear and pain at the mastoid bone- more
  work up may be needed

22
EARS

• Diagnostic Tests
• Tests are rarely needed. Should use pneumatic
  otoscopy. Tympanogram may be helpful measuring
  otitis with effusion. Cultures are rarely done,
  but are helpful. X-ray or CT of sinuses or of
  mastoid area maybe indicated. CBC with severe
  illness maybe indicated. Hearing tests are
  needed in some cases or at follow-up

23
EARS

• Differentials for OM
• OE
• Barotrauma
• TMJ
• Mastoiditis (always coincides with AOM)
• Cerumen impaction
• Parotitis

24
EARS

• Otitis Management/Follow-up
• AOM
• If over 2 years old, watchful waiting for three
  days
• If present longer than three days treat for most
  common organism
• Amoxil is first line
• Recheck children in 2-3 weeks, and adults if pain
  or other symptoms return
• OME
• Watchful waiting is indicated, recheck every 4-6
  weeks for 3-4 months
• Steroids are sometimes used for 7 days
• Nasal steroids used more often for 3 months
• Rarely an antibiotic is tried

25
EARS

• Select based on the likely pathogen
• AMOXIL FAILURE b/c hflu/mcat instead of s.pneumo
  OR highly resistant
  s.pneumo
• High dose Amoxil ? failure? Augmentin-gt failure-gt
  Ceftriaxone (50 mg/kg /d) x3 consecutive days
  IM/IV
• Alternatives cefdinir/Omnicef,
  cefpodoxime/Vantin, or cefuroxime/Ceftin.
  (BLactam no better aga Spneumo)
• If AOM persists, tympanocentesis should be
  recommended to make a bacteriologic diagnosis.

26
Rhinitis

• Rhinitis or coryza inflammation of the nasal
  mucosa with congestion, rhinorrhea, sneezing,
  pruritus, post nasal drip
• Allergic
• Seasonal or perennial
• Nonallergic
• Infectious, irritant related, vasomotor,
  hormone-related, associated with medication, or
  atrophic
• May be chronic or acute
• Most common types
• Viral
• Perennial (hay fever)

27

• Epidemiology/Causes
• Actual prevalence is undocumented, but is very
  common
• Occurs at least as much as the common cold
• Estimated 40-50 million American adults suffer
• Seasonal allergic rhinitis parallels pollen
  production fall/spring
• Allergic occurs in all age groups
• Most common in adults 30-40 years
• Non allergic rhinitis may be acute or chronic
• Chronic maybe associated with bacterial sinusitis

28
Rhinitis

• Epidemiology/Causes
• Atrophic rhinitis affects older adults, but
  symptoms may begin in the teens
• VIRAL URIs are more frequent in families with
  young children
• Exposure to offending allergens is the main risk
  factor of allergic rhinitis
• Vasomotor rhinitis is aggravated by low humidity,
  sudden temperature or pressure change, cold air,
  strong odors, stress, smoke
• Certain drugs may precipitate rhinitis- ACE,
  beta-adrenergic antagonists, some
  anti-inflammatory agents, even asa

29
Rhinitis

• Rhinitis Patho
• Viral
• Viral replication in the nasopharynx with varying
  degrees of nasotracheal inflammation. Associated
  with viral upper respiratory tract infection
  (COLD)
• Etiologic agents
• Rhinovirus, influenza, parainfluenza, respiratory
  syncytial, coronavirus, adenovirus, echovirus,
  coxsackievirus
• Most rhinosinusitis is viral
• Bacterial super-infection rarely occurs

30
Rhinitis

• Rhinitis Patho continued
• Allergic rhinitis
• results from immunoglobulin E (IgE) mediated type
  I hypersensitivity to airborne irritants
  affecting the eyes, nose, sinuses, throat, and
  bronchi
• IgE antibodies bind to eosinophils and basophils
  in the bloodstream and the mucosal mast cells.
  These leukocytes degranulate, releasing chemo
  inflammatory substances including histamine,
  leukotrienes, prostaglandin's, slow-reacting
  substance of anaphylaxis, and erythrocyte
  chemotactic factor, resulting in increased
  vasodilatation, capillary permeability, mucus
  production, smooth muscle contraction and
  eosinophilia- wow that sounds BAD
• May also be caused by food allergies

31
Rhinitis

• Rhinitis Patho continued
• Vasomotor rhinitis is chronic, noninfectious
  process of unknown etiology without accompanying
  eosinophilia, characterized by periods of
  abnormal autonomic responsiveness and vascular
  engorgement unrelated so specific allergens
• Causes include- hormonal changes, medication
  overuse, bacterial infection-which can cause
  atrophic rhinitis

32
Rhinitis

• Rhinitis symptoms
• Viral-malaise, HA, substernal tightness, rare
  fever, sneezing and coughing
• Allergic-itching of all upper air way mucosa,
  watery eyes, sore throat, sneezing, coughing
• Vasomotor-watery nasal discharge, nasal speech,
  mouth breathing, nasal obstruction that switches
  sides

33
Rhinitis

• Rhinitis objective findings
• Viral- nasal mucosa appears erythematous, throat
  will appear erythematous and edematous, external
  nose may appear erythematous, with a crease
  across the nose (allergic salute). May have
  swollen turbinates and tonsils. On palpation, the
  nasal mucosa appear friable.
• With a secondary bacterial infection the
  discharge may be green/yellow in adults only!!
  Color is children does not matter!!

34
Rhinitis

• Allergic mucosa are pale, boggy (swollen) and
  may look bluish. Yellowish, gray or red mucosa
  may also be seen. Polyps of various colors may
  be seen with chronic perennial rhinitis.
  Conjunctivae are inflamed with palpebral
  conjunctiva and cobble-stoned in appearance.
  Dark circles under the eyes (allergic shiners)
  may be seen. Wrinkles across the bridge of the
  nose may be seen.

35

42
Sinusitis

• Sinusitis is an inflammation of the mucous
  membranes of one or more of the paranasal
  sinuses frontal, sphenoid, posterior ethmoid,
  anterior ethmoid, and maxillary
• Acute-abrupt onset of infection and
  post-therapeutic resolution lasting no more than
  four weeks
• Subacute with a purulent nasal discharge persist
  despite therapy, lasting 4-12 weeks
• Chronic, with episodes of prolonged inflammation
  with repeated or inadequately treated acute
  infection lasting greater than 12 consecutive
  weeks

43
Sinusitis

• Epidemiology and causes
• Frequency of colds accounts for the frequent
  occurrence of sinusitis. About 0.5 of all
  colds are complicated by bacterial infection of
  one or more of the paranasal sinuses
• Acute bacterial sinusitis accounts for 16 million
  visits a year
• Chronic sinusitis is the most common chronic
  disease in the US

44
Sinusitis

• Sinusitis Patho
• Vast majority of acute sinusitis are caused by
  the same viruses found in URIs
• Viral rhinosinusitis is most common
• Which is the most common cause for acute
  bacterial sinusitis, from complications in about
  2
• Sneezing sends fluid from the nares and nasal
  cavity into the sinuses which is a great place
  for microbial replication
• The only reliable way of identifying causative
  organisms in acute sinusitis is direct sinus
  aspiration

45

November 30, 2009 A review article published in
the November 15 issue of American Family Physician

• Nasal irrigation using liquid saline may be
  helpful to manage symptoms of chronic
  rhinosinusitis that persist for 12 weeks or
  longer, and this is the most common indication
  for saline nasal irrigation. In 1 study included
  in a Cochrane review, daily use of 2 liquid
  saline, but not spray saline, in addition to
  routine care was associated with a 64 reduction
  in overall symptom severity vs routine care
  alone. These patients also had significant
  improvement in disease-specific quality of life
  at 6 months and at 18 months.

52
Sinusitis

• Sinusitis follow up
• Varies per provider
• With increase symptoms recheck
• If no better in 5-7 days recheck

• Visual changes, cellulites, severe fever,
  aphasia, palsy, seizures, altered mental status,
  osteomyelitis, swelling, meningitis, empyema,
  abscess

53
Sinusitis

• Sinusitis patient education
• Should focus on the worsening of symptoms
• Avoid all contributing factors
• Smoke, allergens, antihistamine
• Increase fluids!

54
Pharyngitis

• Pharyngitis and tonsillitis are generalized
  inflammatory process of both infectious and non
  infectious etiology
• Most cases are viral and self-limiting
• Most cases of pharyngitis are contagious
• All cases of tonsillitis are contagious

55
Pharyngitis

• Epidemiology
• 8 of all office visits
• Viral more common in cold weather
• GABHS increases from 10 in fall to 40 in winter
• Causes
• Herpangina, EBV, URI, postnasal drip, sinusitis,
  chronic illnesses, leukemia, stress, alcohol,
  gonorrhea, syphilis, herpes, diphtheria, candida,
  tobacco, marijuana

56
Pharyngitis

• Patho
• 40 of cases have no know cause
• URI is 30-50
• Influenza, coxsackievirus, enterovirus, RSV,
  Rhinoviruses, CMV, EBV, HIV
• Bacterial typically cause exudates
• Which is 20 of sore throats
• GABHS is 10-20 of adult cases and could lead to
  the most serious complications like heart
  disease, and rheumatic
• 80 serotypes of streptococcus
• Most significant stain based on the M protein
  which is antiphagocytic, and if a patient becomes
  immune to this bacteria, it provides protection
  for future infections of this type

57
Pharyngitis

• Patho continued
• Streptococcus pyogenes strains are more virulent
  with more renal disease side effects
• Streptococcus exotoxins can cause bacteremia,
  deep tissue cellulitis, toxic shock

  bronchitis

58
Pharyngitis

• Patho continued
• Non-infectious causes of pharyngitis
• Trauma, allergies, collagen vascular disease,
  autoimmune blistering disease, chemical/drug
  damage, severe dehydration.
• Patho of Tonsillitis is usually an infectious
  disorder, with swelling and exudates with the
  same causes, but GABHS is common

59
Pharyngitis

• Subjective findings

• Cough and congestion are rarely present
• Allergic pharyngitis does not present with fever
• Mono has a gradual onset of low grade fever and
  fatigue
• Influenza will have abrupt onset with headache
  and body pain also, then followed by a cough.

61
Pharyngitis

• Objective for pharyngitis
• Inflamed throat, erythematous
• Conjunctivitis is associated with adenovirus
• Exudates and large tonsils occur rarely with
  viral illness
• EBV may present with exudate and swollen PCN and
  increase spleen and liver size
• Strep produces a white exudate or Forchheimer
  spots (palatal petechia), they may also have a
  sandpaper rash on their body and/or Pastia's
  lines
• Sometimes called scarlatina or scarlet fever
• C diphtheria has a grayish pseudomembrane over
  the mucosa of the pharynx
• Tonsillitis has swollen posterior lymph glands on
  either side of the jaw

62
Pharyngitis

• Testing
• Not needed often, due to the self-limited nature
  of these illnesses
• Best test is a rapid strep test with a back up
  throat swab culture
• To justify a rapid test the patient should have
  two or three of the following
• Fever over 100.5, tonsillar exudes or Forchheimer
  spots( palatal petechia), tender anterior
  cervical lymphadenopathy, absence of cough
• Patients meeting four of these may be treated
  empirically
• Is better to document with a quick strep antigen
  test!!
• Throat swab is gold standard test
• Anti-streptolysin (or ASO) for blood detection of
  strep

63
Pharyngitis

• Testing continued
• Viral throat swab cultures are used to detect
  herpes virus as well other viral infections
• Tzanck smear of a exudate is used to detect HSV,
  and herpes zoster

Temporomandibular Joint (TMJ) Disease

• TMJ is a collective term that refers to disorders
  affecting the masticatory musculature and
  associated structures. Sometimes know as
  temporomandibular disorder. TMD is a cluster or
  related disorder that have many features in
  common.
• The most common is pain in the muscles of
  mastication, the preauricular and the TMJ
• Is a sub classification of musculoskeletal
  disorder

69
Temporomandibular Joint (TMJ) Disease

• Epidemiology
• 75 of people have at least one sign of joint
  dysfunction and 33 have at least one symptom,
  like face pain
• Only about 5 are in need of treatment
• Differentiate contributing factors
• Predisposing factors- increase the risk
• Initiating factors- cause the onset
• Perpetuating factors- interfere with healing

70
Temporomandibular Joint (TMJ) Disease

• Have you had jaw joint problems before
• Does your jaw ever get stuck
• Is opening your mouth difficult or cause you pain
• With ringing in the ear does opening or closing
  you mouth change the sound

  technique
• Start with the mouth closed then open

73
Temporomandibular Joint (TMJ) Disease

• Testing
• Ruling out other underlying conditions
• CBC, CMP, ESR, rheumatoid factor, TSH, X-RAY
• Diagnosis may be made by history and exam
• Refer to
• Dentist, otolaryngologist, oral surgeon
• They may order CT which gives the best picture of
  the osseous structures, or MRI to show arthritic
  changes or disk displacement

74
Temporomandibular Joint (TMJ) Disease

• Differential diagnosis
• Must sort out the list of contributing factors
  and potential symptoms
• Accurate DX is essential
• Disorders of the intra-cranial structures should
  be ruled out
• New or changes in symptoms must be assessed
• I.e. weight loss, ataxia, fever, seizures,
  paralysis, vertigo

75
Temporomandibular Joint (TMJ) Disease

• Differentials continued
• Sinusitis, arthritis, glaucoma, lyme disease, OM,
  OE, temporal arteritis, neuralgia, mastoiditis,
  abscess, migraine, anxiety, depression,
  hematoma-- to name a few

76
Temporomandibular Joint (TMJ) Disease

• Management
• Involves understanding and treating the whole
  patient
• Goals for management- reduction of pain,
  restorations of acceptable function
• Initial TX designed to be palliative and promote
  healing, with self-help techniques and
  pharmacotherapy
• Adjustment of diet
• Education and alteration of oral habits (gum
  chewing)
• ICE/ HEAT
• PT
• Medications such as pain meds, anti-inflammatory
  meds, injection of trigger points
• Most care will be given by the specialist

77
TMJ

• Follow up and referral
• Refer to a specialist is best idea for real TMJ
  disease

78
TB

• TB
• Testing
• Tuberculin skin test remains the standard test
  for determining infection with Mycobacteria
