Objectives..
Identify and discuss new and re-emerging diseases,
specifically focusing on their cutaneous
presentations, using current events as the template
Discuss the impact of antibiotic overuse on these
particular diseases
Heighten knowledge base regarding HIV and how it
manifests cutaneously
Provide a refresher on melanoma recognition
Top Five Emerging Diseases for 2017
Leishmaniasis
Rift Valley Fever
Mosquito - virus
Mayaro
Mosquito - virus
Oropouche
Sandfly - parasite
Mosquito - virus
Elizabethkingia
Mosquito - bacteria
CHIKUNGUNYA
“To become contorted”
Due to severe joint pain which may be chronic
High fever
Headaches
2-12 days after bite
Rash – viral exanthem – 73% of patients
Asymptomatic in most; mildly pruritic in others
Appears 3-5 days after the onset of fever
Diagnosed by ELISA
IgG and IgM antibodies
Highest 3-5 weeks after onset
Other cutaneous findings…
Desquamation of the palms
Peno-scrotal and perianal ulcerations – 24%
Punched out
2-5 weeks after fever
Aphthous like ulcers on the tongue, palate, lips, etc
Lymphedema
2-3 weeks after onset
Vasculitic and EN like lesions
Exacerbation of previous cutaneous diagnoses
Dengue….
“Notifiable” since 1990
Fever in the presence of one or more of the following
Nausea/vomiting
Rash
Headache/retro-orbital pain/arthralgia/myalgia
Leukopenia
Persistent abdominal pain
Hepatomegaly
Pleural/pericardial effusions
Increased hematocrit with decreased platelets
Dengue…
DENV 1, 2, 3 and 4
Estimated: 40% of world’s population at risk
Mosquitos with virus are currently found in
Florida
Louisiana
New Mexico
Arizona
Texas
California
Utah
And…as far north as Illinois and New York
Treatment
Supportive….
Cautious not to fluid overload in DHF
Aedes
Aegypti
Mosquitoes
Microcephaly
What about…
Reports of
Sexual
Transmission
ZIKA?
Guillian
Barre
Signs and Symptoms…
1 in 5 infected become ill
Flu like symptoms: fever, headache, myalgia,
macolupapular pruritic rash, nonpurulent conjunctivitis
Incubation period is about one week
Zika can survive in sperm for up to 6 months
Can affect the fetus if exposed anytime during
pregnancy – highest risk prior to 18 weeks gestation
Labs
First week: RT-PCR for Zika
Second week: IgM and IgG
After two weeks: urine RT-PCR
How is it different?
Zika vs Chikungunyna
No arthritis
No facial rash
No vesicles/bullae on genitalia
Zika vs Dengue
No high fever
No shock
No hemorrhagic manifestations
Chagas..
5% mortality rate
Myocarditis
Thromboembolism
Encephalitis
Chronic Cardiac
RBBB; cardiomyopathy; third degree atrioventricular
block; CHF
Chronic GI due to persistent T cruzi infestation
Megaesophagus
Megacolon
Psoriasis
Most common autoimmune disorder in US
7.5 million Americans (2% of population)
New Treatments

PO
Rash..
Lyme Disease and STARI
Erythema Migrans
Anaplasmosis –
rarely presents
Tularemia
Ulcer at site and regional lymphadenopathy with a rash
Rocky Mountain Spotted Fever
Babesiosis
10% do not develop a rash
Small, pink macules on arms, legs, trunk; eventually petechial
lesions
Maculopapular to petechial; splinter hemorrhages; ecchymosis
Ehrlichiosis
Rarely presents with rash
Erythrodermic or similar to RMSF
Conjunctivitis is common
Treatment??

and Quinine
Ehrlichiosis
Tick Borne Spotted Fever
Doxy
Doxy
Treatment options with history of
attached tick….
All people
People with higher risk due to attachment of tick
longer than 36 hours
All people who develop erythema migrans or other
signs and symptoms of tick-borne infection
All people who seroconvert from negative to
positive for serum antibodies
Outcomes…
Prevent exposure to vector
Routine use of antibiotics and serological testing IS NOT
recommended
Single dose doxycycline can be used if tick is attached longer
than 36 hours and if doxy can be started within 72 hours of
tick removal
Local infection rates in ticks is >20%
Adults: 200 mg dose
Children > 8 yo: 4mg/kg but not more than 200 mg
Pts should be monitored for 30 days for signs and symptoms
of tick-borne infections and treated accordingly

other organisms

Pyogenes
Nares cultures – 77.8% resistance in
staph. aureus
Gonorrhea
246,000 drug resistant infections
188,600 to TCN
11,480 to Cefixime
3,280 to Ceftriaxone
2,460 to Zithromax

CDC Antibiotic Stewardship
Take an “antibiotic time
out” – reassessing
antibiotics after 48-72
hours
All orders should have:
Dose, duration and
indications
Get cultures before
starting antibiotics
It has been estimated
that nearly half all
prescriptions written
are “unnecessary”
Maine
Vaccination Rates
Measles complications
1:10 children develop perm. hearing loss
1:20 children develop pneumonia ~ the most common cause
of death in children with measles
1:1000 develop enchephalitis
2:1000 die
Rare~ Subacute Sclerosing Panenchephalitis (SSPE)
Develops 7-10 years after the measles infection
Involves the CNS
Fatal
11:100,000
Supernumerary Nipples

1 in 100 men
1 in 50 women
Symptoms of breast cancer can be found in extra nipples; but
not linked to increased risk

Cause ~ not completely understood
“Autoimmune disorder”
Absence of functional or recognizable melanocytes
Destroyed by T cells
Presence of circulating antibodies
Vitamin deficiency??
Maybe – an over reactive response to protect against MM
0.5-2% of population
More females than males?
Not statistical – more females present
Average age of onset: 20 years old
Treatments??
TCS
Tacrolimus 0.3-1% ointment
Vitamin supplements? (C, Folic Acid, B12)
Depigmentation with hydroquinone 20% -
Monobenzone – only FDA approved tx
Surgical: punch minigrafting
Melgain??
New Treatments??
Interferon gamma pathway (IFN-y)
Specifically CXCL10 chemokines
Biologics in Phase 1
Xeljanz (tofacitinib citrate)– used to treat RA
Afamelanotid and Narrowband UVB
Melanocyte stimulating hormone
Developed by the University of Arizona
1873 Medical records reviewed
20% had at least one comorbid diagnosis
Alopecia areata
Addison disease
Autoimmune gastritis
IBD
Pernicious anemia
Psoriasis
RA
Systemic lupus
31 fold increase in frequency of alopecia areata than general population
Also found association with: Guillain-Barre, myasthenia gravis, linear morphea,
discoid lupus and Sjogren syndrome
Malignant Melanoma
Third most common, but most deadly
Estimated 76,380 new cases will be diagnosed in 2016
2017: 87,110 new cases
10,130 people will die/ one person every 57 mins
2017: 9,730 deaths
Of the 7 most common cancers in the US, MM is the only one
that continues to increase in incidence
Cause: sun, tanning bed, genetics (Jimmy Carter)
Men Vs Women
Men
Majority of MM cases are
white men over the age of
50
60% of MM deaths
5th
most common cancer in
men
Women
39 and under have a higher
chance of developing MM
than any other cancer
Leading cause of death in
women 25-30 yrs old
7th most common cancer in
women
Ethnicity
60-75% of MM arise on areas of less pigment in people
of color: palms; soles; nail beds and mucous membranes
MM is uncommon in people of color ~ approximately
1:100,000
Late stage diagnoses are more prevalent among people
of color ~ therefore MM is more likely to be fatal
Kids and Melanoma
MD Anderson
500 children nationwide diagnosed with MM yearly
John Hopkins study
Children more likely than adults to have metastasis
to sentinel lymph node
Children with metastasis : 25%
Adults with metastasis: 14%
New Statistics - Kids
90% of pediatric cases: 10 – 19 years old
6.5% occur in non-Caucasians – higher than adult
statistics
Diagnosis and treatment is delayed in 40% of pediatric
melanoma cases
Second most common form of cancer: ages 15-29
Let’s talk tanning beds..
First commercialized in US in 1978
But…Coco Chanel brought the tan into vogue after
a trip to the French Riviera in 1929
In 1978– 500,000 cases of skin cancer yearly
Now – 3.5 million yearly (melanoma and
nonmelanoma)
20 mins of tanning bed = damage of 3-5 hours of
natural sun
Ohio HB 131 Sec:4713.50
Passed the House summer 2014
Tanning bed regulations
Over 18: must obtain consent from individual
Between 16- 18 years old: must obtain consent from
parent – good for 90 days; parent must remain on
premises; no more than 45 sessions in 90 day period
Prohibited for children under 16 years of age
Jimmy Carter’s treatment..
Keytruda (Pembrolizumab)
Side effects - few
Monoclonal antibody
Rapid FDA approval in 2014
30 min infusion Q 3 weeks
Based on weight; cancer, etc
Itching; cough; nausea; anemia; rash; fatigue, constipation,
arthralgia, diarrhea, etc
Effectiveness?
Only 1/3 respond
Those who do…respond quickly with immediate shrinking of
tumors
