The document discusses the use of energy-based devices like lasers in treating sexually transmitted diseases (STDs). It provides an overview of different types of lasers and their applications in managing various STDs. Specifically, it describes how carbon dioxide lasers can be used to treat genital warts and condyloma acuminata through ablation and vaporization. Studies show carbon dioxide laser therapy is an effective treatment for STDs like genital warts, with benefits like being painless, allowing quick healing, and having low recurrence rates compared to other options. The document outlines the evolution of laser technology and its increasing use in dermatology and management of STDs over time.

Trends of Five Common Sexually Transmitted Infections
14. • New therapeutic strategies are urgently needed to overcome
drawbacks in the treatment of some infections, particularly sexually
transmitted infections (STI).
• Several treatment options are developed for eradication of STI, laser
therapy has been shown to be effective in a number of conditions
• Light amplification by stimulated emission of radiation (laser) is a
device that amplifies light and produces coherent light beams.
• The root of this technological innovation lies in physics research.
• The benefits of laser therapy are that it is often a painless procedure
and patients are able to heal quickly with lower infection levels and
low rates of recurrence and complications

19. Type of Lasers
Features of the carbon dioxide laser are:
• Wavelength in the far infrared range
(10,600 nm); in tissue, the energy of this
quality will be fully absorbed by the
watermolecules.
• This implies that the effect of the carbon
dioxide laser is very superficial with a
limited penetration of less than 0.1 mm.
1,2
• The first effect on the skin is coagulation
of the epidermis and uppermost dermis
(whitening): then blistering of the
epidermis (irradiance < 80 W/cm2) will
occur.

• These light beams are poorly absorbed
by the hard tissue and therefore do not
damage nearby hard tissue.
• By focussing the beam on the desired
area for incision, a highly precise focal
spot can be created. By adjusting the
focus of the beam, the intensity of the
laser light can be varied, which allows
cauterization of small blood vessels and
lymphatics to decrease post–operative
swellings and sealing of nerve endings to
reduce post-operative pain.
• Diode lasers are semiconductors that
change electrical energy into light energy
through the use of solid‐state elements,
such as aluminum and gallium.
• The light beam which is released by the
diode laser falls within the visible and
invisible range of near infrared waves
(with wavelengths varying between 800
and 980 nm) and is able to vaporize soft
tissue due to its high water content.

33. • The Holmium:YAG (Ho:YAG) laser is a highly
comprehensive tool, using the doping
element holmium as an active medium in a
yttrium-aluminium-garnet (YAG) crystal.
• It is a solid-state, pulsed laser designed for
emitting light at 2100 nm, which is invisible to
the human eye and is in the near-infrared
region of the electromagnetic spectrum.
• Considering that the holmium wavelength can
be transmitted down optical fibers, the
Ho:YAG laser has become a multi-purpose
tool in treatment options
• The optical absorption coefficient for water at
this wavelength is approximately 40 cm-1 so
that the holmium wavelength is absorbed
significantly by water.
• Since tissues are composed mainly of water,
the majority of the holmium energy is
absorbed superficially and this results in issue
cutting and coagulative hemostasis.

This study showed treatment with holmium laser is correlated
with highest clearance rate (92.2%) and lowest recurrence rate
(14.3%) than other applied treatments.
In conclusion, holmium laser is safe, and more effective, than
other methods.

The ND-YAG laser machines produce a good
coagulation at a depth of 4-6 mm. and may
therefore be of great value particularly in
the treatment of vascular inflammatory or
tumorous diseases of the skin such as KS or
botryomycoma.
• Due to the emitted wavelengths of
1,064, 532 and 355 nm, the energy is
absorbed partly by the water molecules
but also by melanin pigment and
hemoglobin.
• In accordance with the lower superficial
absorption rate compared to the carbon
dioxide laser, the energy transfer to the
deeper layers is higher This results in a
deeper tissue penetrance than with the
carbon dioxide laser.

41. • Exposure of the condylomata to the Nd-YAG laser beam resulted in an
immediate vaporization of the lesions with smoke formation.
• A biopsy performed immediately after the laser therapy showed
destruction of the entire epidermis extending through the upperdermis
to a total depth of l mm .
• These wounds were treated daily with sulfadiazine cream and healedin
threeweeks without leaving a visible scar.

42. • In this laser type,the primary tissue
chromophores are melanin pigment and
hemoglobin.
• Produces a blue-green light that has two
distinct bands at 488 nm and 518 nm
• Can be transmitted through water or
quarts fibers of 200 to 600 micron
diameter
• Hemoglobin and other deeply colored
pigments absorb their wavelengths and
are responsible for their use in vascular
and pigmented lesion
• Penetration into skin, typically 1 to 2mm, is
affected by the concentration of skin
pigments.
• It produce a moderate scatter 100 times that
of CO2 laser. This results in an excellent
hemostasis.
• Because of scatter, they have minimal cutting
ability. The depth of tissue injury is roughly
correlated with the laser power settings.

43. • Another antimicrobial PT strategy, water-
filtered infrared A combined with visible light
irradiation, has been shown to be effective
against genital Chlamydia trachomatis
bacterial infection, and an optical nano-
genosensor has been designed for the
diagnosis of trichomoniasis, a parasitic
Trichomonas vaginalis infection
• Phototherapy is a major therapeutic
approach based on the controlled
administration of light in the visible, near
infrared, or UV spectrum, with or without
the application of an external
photosensitizer.
• Despite the fact that Phototherapy has not
been explored to its full potential in the
control of STIs, it has already demonstrated
good clinical response rates and lower
recurrence rates in genital infections.

(B) The combination of water-filtered infrared A (wIRA) with visible light VIS (wIRA/VIS) is used for killing
intracellular and extracellular Chlamydia trachomatis strains in Vero and HeLa cell lines. Visible light

46. • Pulsed dye laser (PDL) has been commonly
used in the treatment for viral warts.
•Although the mechanism of action for PDL
treatment for warts is not fully known, it is
thought that this method is based on the
specific destruction of superficial dilated
capillaries in warts by selective
photothermolysis of oxyhemoglobin within the
microvasculature.
•The damage of virally-infected keratinocytes by
PDL may contribute to the treatment for warts
because the human papilloma virus is heat-
sensitive

• The application of 585-nm flashlamp-pumped pulsed
dye laser (FPDL) light represents a safe and simple
treatment option for its effectiveness being
comparable with that of conventional therapies
• The paring the keratotic component of warts with a
blade, to the extent that blood vessels are
seen without causing bleeding before PDL treatment,
is thought to provide deeper penetration of the laser
light
• Efficacy of PDL treatment for viral warts have shown
variable response rates as with other treatment
modalities.

49. • The Thulium laser has a stable
controllability of the tissue effect
because of the high absorbance of
energy in water.
• The light is generated as a continuous
wave
• The Thulium laser has a wavelength of
2.0 um, allowing the wavelength to
match the 1.92 um water absorption
peak in tissue.
• The high density of absorbed energy at
the tissue surface leads to instant
vaporization and limits the penetration
depth to 500-2,000 mm, depending on
the power settings, which is a
reasonable depth for sufficient
hemostasis with minimal thermal injury
to surrounding tissue.

55. Take Home Messages
Despite the range of treatment options available, energy based device has been able to achieve satisfactory
results in STDs
Further study should be conducted to identify the best therapeutic strategy in STDs.
Therefore energy based device can be considered as an alternative method for treating genital lesions in STDs,
with satisfactory results in terms of pain, aesthetic and minimal recurrence
It can be done in outpatient clinic with local anesthesia so can get ride from side effect of general anesthesia and postoperative pain. Good
dermatological outcomes aid to further improve patient satisfaction
