Warts Diagnosis and Treatment



Warts Diagnosis and Treatment
By:Rick Lin, DO MPH
Texas Division of KCOM Dermatology Residency Program

Background Information
* Warts are small harmless lesions of the skin
* caused by a virus: the human papilloma virus.
* The appearance of warts can differ based on the type of wart and where it is located on the body.
* Warts are common in children. Most cases occur between ages 12-16 years.
* Up to 30% of warts disappear by themselves within 6 months. Most will disappear without any treatment within 3 years.
* Warts are caused by the DNA-containing human papillomavirus (HPV). There are at least 63 genetically different types of HPVs.
* The virus enters the skin after direct contact with recently shed viruses kept alive in warm, moist environments such as a locker room, or by direct contact with an infected person.
* The entry site is often an area of recent injury. The incubation time—from when the virus is contracted until a wart appears—can be 1-8 months.
* Contrary to popular mythology, touching a frog will not give you warts.

Types of warts
* Common warts (verrucae vulgaris): These common warts typically develop on the hand, especially around the nail. They are gray to flesh colored, raised from the skin surface, and covered with rough, hornlike projections.
* Plantar warts (verrucae plantaris): Plantar warts, by definition, occur on the plantar surface, or bottom, of the foot.
* They usually occur in high pressure areas such as the heel and the metatarsal heads (just behind the toes).
* They usually grow into the skin, not outward like common warts.
* This growing into the skin makes them more difficult to treat.
* Flat warts (verrucae plana): Flat warts are most commonly seen on the face, the back of the hands, and lower legs.
* They usually appear as small individual bumps about 1/4 inch across.
* Flat warts may spread rapidly on the face and lower legs from the activities involved in shaving.

Histopathology
* Verruca vulgaris (common wart) is caused by varous strains of human papilloma virus (HPV 1, 2, 4, 7, 26-29).
* Macroscopically verruca vulgaris may present as hard, rough surfaced papule
2 – 20 mm (solitary or multiple).
* Microscopically, this is an exophytic, symmetric, papillomatous lesion with large keratohyaline granules and characteristic inturning of the rete ridges.

Histopathology
* Parakeratotic columnar tiers of stratum corneum overlie the papillomatous surface.
* Small amounts of hemorrhage may be present within the columns of parakeratosis.
* Other characteristic features include koilocytosis, hypergranulosis and presence of multinucleated cells.

Treatment
* Home care is effective in making the wart or warts go away. No matter what technique you use, warts will disappear 60-70% of the time.
* Techniques may be done with and without medication.
* The ultimate goal of the medical therapies (not the surgical treatments) is to get your body to recognize the wart as something foreign and to destroy it, much like the body destroys a cold virus.

Adhesive tape therapy
* Place several layers of waterproof adhesive tape over the wart region (even duct tape).
* Do not remove the tape for 6-1/2 days. Then take off the tape and open the area to the air for 12 hours.
* Reapply tape for another 6-1/2 days.
* The tape works best in the region around the fingernail.
* Tape works because the air-tight, moist environment under the tape does not allow the virus to grow and reproduce

Salicylic acid therapy
* Salicylic acid is available by many different trade names at the drug store.
o Dual Film
o Wart-Off
o Dr. Scholl’s Wart Medication
o Medi-Plast
* It comes either as a liquid to paint on the wart or as a plaster to be cut out and placed on the wart tissue.
* The area with the wart should be soaked in warm water for 5-10 minutes.
* The wart should then be pared down with a razor. A simple razor works fine for this, then throw it away.
* Do not shave far enough to make the wart bleed.
* Apply the salicylic acid preparation to the wart tissue.
* Do not apply it to other skin because of salicylic acid's potential to injure normal tissue.
* Follow directions on the package for how long to apply the acid.

Cryosurgery
* Liquid nitrogen or cryotherapy is used to deep freeze the wart tissue.
* With liquid nitrogen applied to the wart, the water in the cells expands, thus exploding the infected tissue.
* The exploded cells can no longer hide the human papillomavirus from the body's immune system.
* The immune system then works to destroy the virus particles.
* Periungual area may scar if cryotherapy with liquid nitrogen is used improperly.
* Scarring could lead to permanent nail disfiguration.

Laser Therapy
* Laser therapy: Lasers are simply very intense light sources.
* This light has an enormous amount of energy that heats the tissue enough that it vaporizes.

Shave Removal
* Shave removal and electrodessication of the base may be necessary when other treatment methods fail.
* This would involve numbing the region around the wart and shaving the wart flat with the surface and light electrodessication of the base.

Prognosis:
* Most warts will disappear without treatment anywhere from 6 months to 3 years.
* Warts may recur after treatment and require additional treatments.
Prevention:
* Avoid touching warts on others or touching them on yourself (refrain from rubbing a warty finger across your face).
* Children needs to avoid biting or chewing warts.
* Wear shower shoes in the gym locker room to lower your risk of picking up the virus that causes plantar warts from the moist environment.

When to Refer
* If you feel uncomfortable treating warts.
* Warts that are resistant to your treatment
* Unsure of diagnosis

Female Genital Cutting



Female Genital Cutting
By:Safa Magid

Female Genital Cutting(FGC)
* Also known as: female circumcision & female genital mutilation
* Female circumcision is the term preferred by cultures who practice this custom

FGC -Definition
* Procedure involving partial or total removal of the external female genitalia or other injury to the female genital organs whether for cultural, religious, or other non-therapeutic reasons.

WHO Classification of FGC
* Type 1: Excision of prepuce w/ or w/o excision of all of the clitoris
* Type 2: Clitoridectomy and partial or total excision of labia minora
* Type 3: Infibulation, includes removing all or part of ext. genitalia and re-approximation of remnant labia majora, leaving a small interoitus for passage of urine and menstrual blood

* Type 1 and Type 2 are the most common forms
* Type 1 and Type 2 account for 80% of the cases
* Infibulation accounts for 15% of the cases

FGC
* Currently ~ 130 million women and girls have had the procedure
* An estimated 2 million girls worldwide are at risk per year

FGC in the US

* Data from 2000 census suggests:
228,000 women and girls are with or at risk for FGC in the United States
* CA, NY, and MD have the most female immigrants and refugees from countries where FGC is prevalent.
* Occurs mostly in 28 sub-Saharan African countries
* FGC is practiced by Christians, Muslims, and adherents to traditional African religions
* Also practiced in Middle East and Asia

Origins and History
* Origins remain unclear
* FGC practiced in Pre-Islamic Arabia, ancient Rome, and Tsarist Russia
* Female circumcision was discovered in ancient Egyptian mummies in 200 B.C.
* Practiced in the United States until the 1970’s to tx hysteria, lesbianism, and erotomania

FGC and Religion
* Christianity:
FGC is not an obligatory religious requirement
* Islam:
FGC is not an obligatory religious requirement

FGC-Procedure
* Performed between the ages of 5-10, or prior to marriage
* Performed by a member of community who is not a healthcare worker
* Often performed w/o anesthesia
* However in metropolitan areas the use of anesthesia is more common

FGC Procedure
* Performed w/o surgical instruments. Razor blades or other instruments which may or may not be sterile are used
* Depending on socio-economic factors FGC may also be performed in a health care facility by qualified health personnel
* WHO is opposed to medicalization of all types of female genital mutilation.
* Reasons currently practiced:
o Rite of passage to womanhood
o Maintains chastity
o Ensure marriageablity
o Belief that it improves hygiene
o Social pressure to adhere to custom
o Belief that it is a religious requirement

Complications
* Prevalence of complications is unknown
* Rate of complications increase with severity of procedure( i.e. women with type III have > complications that women w/type I)
* A study of 120 Somalian women suggests rate of complications are inversely proportional to the age of the child when FGC was performed
* Women who had FGC btwn the ages of 5-8, had more complications than their 9-12 y.o counterparts
* Long and short term complications
* Some women with FGC do not experience complications

Short term complications
* Hemorrhage
* Severe pain
* Shock
* Infection
* Urine retention
* Ulceration of genital region injury to adjacent tissue
* HIV?-Possibly transmitted due to use of unsterilized equipment

Long Term Complications
* Cysts and abscesses
* Post-partum fistulaes: vesico-vaginal
* Keloid scar formation
* Damage to the urethra resulting in urinary incontinence
* Dyspareunia and sexual dysfunction
* Infertility
* Difficulties with labor.

Case Report

* 16 y.o female presents w/severe dysmenorrhea
* PE revealed the absence of a clitoris and fused labia majora with a 1cm opening
* Physicians initially thought pt had corrective surgery for ambiguous genitalia
* Later determined that while visiting Africa with her mother she had FGC performed
* Perinealography revealed:
o Filling of the vagina,urethra, and bladder simulating a urogenital sinus.
o Dilated vagina suggested obstruction
Perinealography

Case Report
* Defibulation procedure was performed
* The patients symptoms of dysmenorrhea eventually resolved

FGC and Obstetric outcomes
* WHO Study

FGC & Length of maternal hospital stay
* FGC and length of maternal hospital stay
o FGC Type I- RR: 1.15
o FGC Type II-RR:1.51
o FGC Type III-RR:1.98

FGC and Mental Health
* Anxiety
* Depression
* PTSD
* Feeling of incompleteness

Defibulation
* Corrective procedure
* Involves division of the fused labia majora with suturing of each labia for hemostasis
* Thus the infibulated scar, which is a flap obstructing the introitus and urethra, is removed
* WHO Indications for defibulation:
* Urinary retention
* Recurrent UTI’s or kidney infections
* Dysmenorrhea
* Dyspareunia or apareunia
* Prior to coitus
* Prior to labor
* It is also reasonable that defibulation can be performed to alleviate any mental health consequences for women who do not meet the WHO indications

Approach to patients with FGC
* Some physicians remain unfamiliar w/FGC & have expressed their shock during PE
* Some women report being reprimanded by physicians for having the procedure done
* Despite the fact the majority had FGC while they were children and were not given a choice

Patients perspective of FGC
* Many pts w/FGC who have immigrated to the West do not feel as if they abused
* Some feel that FGC was done “for them” and not an attack against them

Patients perspective of FGC
* 1st generation pts born in the West who had FGC while traveling abroad often have very different views than their foreign born counterparts
* HC workers may need to modify their approach depending on the pts perspective

Legality of FGC
* U. S. passed a law in March 1997:
* Made performing any medically unnecessary surgery on the genitalia of a girl younger than 18 years of age a federal crime.
* Reinfibulation was not included as a federal crime, so it may be performed with absorbable sutures in a running fashion if a woman chooses the procedure


Resources for pts and HC providers
* African’s Women’s Health Center
o Established in 1999 by Dr. Nawal Nour a Sudanese-American OB/GYN
o Goal of clinic is to provide culturally appropriate holistic care to African women who are refugees who may or may not have undergone FGC
o Defibulation is performed at this clinic

Resources for pts and HC providers
* WHO
* Website with information about FGC
* Includes fact sheet about FGC and guidelines for healthcare workers
* http://www.who.int/topics/female_genital_mutilation/en/
* http://www.who.int/reproductive-health/publications/rhr_01_18_fgm_policy_guidelines/index.html

Dedicated to all of my sisters who have had FGC.
To those who have suffered physical or mental consequences, I am inspired by your courage and strength.
