By: John O. Issis, MD with Medical West
As healthcare providers, It is among our goals to consistently look for opportunities to improve our methods of care for our patients. Because of the day and age we live in, we are always exploring, evaluating, acquiring, and implementing the latest technologies. The team at Medical West and I are excited to share with you one of the latest technologies we use to improve the quality and efficiency of care for our patients.
I am proud to be able to say that we at Medical West were the first hospital in the state of Alabama to use the Spy Elite System in our procedures. The Spy Elite System is a real-time in-operating room technique that enhances the visualization of tissue perfusion. This allows our surgeons to see the performance of blood flow during procedures. In short, we can see where blood is flowing, and where it is not.
Particularly useful during procedures such as mastectomies, breast reconstruction, amputations, head and neck reconstruction, and others - the Spy Elite System allows us surgeons to see the real-time blood perfusion in damaged or replacement tissue - we can look inside and spy on where the blood is flowing.
During an operation, if I would like to have perfusion data, the images can be generated quickly - sometimes in as little as one minute.
The information provided by the Spy Elite System complements my in-operation judgment and decision-making. By adding only as much as five minutes time to a procedure, the Spy Elite System gives me and my partner surgeons the information we need in order to reduce complications and reducing your chance of a return to the operating room.
The Spy Elite System has been a great addition to our operations here, and we make our procedural plans with the Spy in mind.
It's another way our team at Medical West Hospital utilizes advancing technologies to improve and provide the best quality care possible.
Best, Dr. Issis -

Osteoarthritis & Viscosupplementation
I've been asked multiple times by multiple patients if I do, "those chicken injections?" I tell them yes, but we've come a long way from those first injections. The debate over viscosupplementation or Hyaluronic Acid (HA) injections has taken some interesting turns over the last several months.
Hyaluronic Acid is one of the many treatments for osteoarthritis (OA). The exact cause of osteoarthritis is still being researched, but we know the end result is loss of cartilage, "thinner" joint fluid, and the dreaded "bone on bone" X-ray report. There is no way to reverse the process and any "treatments" are only temporary. Most are used as a bridge to a knee replacement. However, for some people, that bridge is all they've got and we'll talk more about that later. Other treatments for OA include lifestyle modifications (rest, avoidance of the irritating activity, etc.), exercise, physical therapy, bracing, medications (NSAIDs, narcotics, etc.), weight loss, and corticosteroid injections. You'll notice that lifestyle modifications and exercise seem to be mutually exclusive. They are not, but it highlights the spectrum of treatments for OA and that there is not a good consensus on treatment.
Here is a little background on HA. Some of the first commercially available products were derived from rooster combs. Some products are still made from an avian source and some are made synthetically from a bacterial culture. Regardless of how it is made, the theory behind HA is two- fold. First, it is to bath the joint in HA in hopes that receptors in the cartilage will "remember" what joint fluid should be and begin making more appropriate joint fluid. Second, it will provide some lubrication to the joint until the medication can take effect. The "gel" is injected directly into the joint (ultrasound guidance can be used, but that is a topic for another blog). This can be done in a single injection or up to 5 weekly injections. Results can be seen immediately, but may take a few weeks to take effect. Maximum benefit is usually seen by 6 weeks and typically lasts around 6 months. The decision as to which product to use and the number of injections is made on an individual basis by the physician and the patient.
Recently, there was a change in the 2013 recommendation guidelines for OA of the knee by the American Academy of Orthopedic Surgeons (AAOS) from inconclusive to strongly against HA injections. The full OA guidelines can be found here (http://www.aaos.org/research/guidelines/TreatmentofOsteoarthritisoftheKneeGuideline.pdf). The recommendation regarding HA is #9. I, along with many in my field of primary care sports medicine, am concerned with these changes. Why is this a concern? It all comes down to reimbursement or the lack there of. There is no denying that the cost of HA injections is high (again a topic for another entry). Insurance companies base their reimbursements on guidelines and recommendation of respected academies and societies, especially when considering an expensive treatment option. We are starting to hear and see some rebuttals to the AAOS. Most notably by the Arthroscopy Association of North America (AANA), American College of Rheumatology (ARC), and Osteoarthritis Research Society International (OARSI), which have returned "uncertain" guidelines. They have all been critical of the methodology used by the AAOS in its meta analysis. A recent article by Dr. Bannuru, a leading expert in meta analysis, pointed out numerous flaws in how AAOS “missed the mark” in developing the recommendations.
The short version of my concerns with this recommendation is as follows. The most glaring is that safety profile is not taken into account, especially when discussing HA vs NSAIDs or Tramadol. HA injections have a very minimal side effect profile and have been routinely found to be safe. NSAIDs, which are currently the gold standard for treatment, or Tramadol, have a well-known side effect profile including bleeding, GI, kidney, and cardiovascular risks. Cost also has to be taken in to consideration when making the argument in HA vs NSAIDS. If you look solely at administration cost, NSAIDs will win out. However, if using NSAIDs as a long term treatment, I believe the cost of complications both monetarily and in quality of living will favor HA. That being said, you can make the argument that NSAIDs should only be used as a bridge to knee replacement. My response would be, "what about the patients that cannot have surgery due to other comorbidities?" This is a patient population that usually already has issues with renal, GI, and cardiovascular disease. A lot of them cannot take NSAIDs, cannot exercise because their joints hurt, and corticosteroids have a worse side effect profile. HA injections can be very useful in this subset of patients. On the other end of the surgery spectrum are young patients with OA. We know that joint replacements will last approximately 15 to 20 years. Ask any orthopedic surgeon and they will tell you that replacing a joint replacement is no fun. If possible, I try to "bridge" patients until their early to mid 60s before having a joint replacement. I cringe at putting a 40 year old on NSAIDs for 20+ years. Yes, the younger patient will do better with weight loss, exercise, and PT, but they usually get better results from HA injections as well.
Second, there are multiple factors to interpret when looking at the effects of HA injections including type of medicine, age, overall health, progression of the disease, and metabolism of the HA. This fact makes it very difficult to make a single overarching statement regarding the utility of viscosupplementation. There are multiple types of HA injection, high, low, and mixed molecular weight preparations. The AAOS guidelines document identified that the efficacy of high molecular weight preparations were significantly better. However, in the recommendation, AAOS did not differentiate among the products. In fact, AAOS included some HA preparations that are not approved for use by the FDA. When looking at the remaining variable factors patient selection will cover age, health, progression of the disease, and metabolism of the medication. The AAOS guidelines do not mention patient selection. Three of the four are easily identifiable and obviously the younger, healthier, and less disease a person has, the better they will respond to any intervention. Metabolism is very difficult to predict. Some patients will be "responders" and some will be "non responders". Unfortunately, at this time the only way to identify this is trial and error, but research is being conducted.
In conclusion, I feel that the 2013 AAOS guidelines are flawed. At worst, an "inconclusive" or "uncertain" recommendation could have been made. At best, multiple recommendations for high vs. low molecular weight HA and proper patient selection could be made. Viscosupplementation is a viable treatment option. It has an outstanding safety profile and can be used in conjunction with other conservative measures. It can be used as either a bridge to knee replacement surgery or for long term treatment. Further research needs to be done to address efficacy and metabolism. In the meantime, we need to do what we can for our patients with OA and that should include the option for hyaluronic acid injections.

Pediatric Allergy and Immunology
By: Dr. Prescott Atkinson_ Director of Pediatric Allergy and Immunology at Children’s of Alabama and a Professor of Pediatrics at UAB
Twenty or thirty years ago, few medicines other than
antihistamines were available to treat allergies. Now, we have a vast and
growing array of pills, sprays, inhalers and injections that provide
increasingly effective treatment for a wide variety of allergic and immunologic
illnesses.
At Children’s of Alabama, physicians in Pediatric Allergy and
Immunology see children with allergic diseases ranging from simple hay fever to
complex, potentially life-threatening conditions such as asthma and anaphylaxis,
a severe reaction that can occur following exposure to stinging insects, foods
or drugs such as penicillin. For instance, we treat chronic or acute hives, and
we treat swelling disorders, particularly hereditary angioedema, which is
marked by terrible, sometimes life-threatening swelling that can cause airway
obstruction.
We also treat children with atopic
dermatitis (allergic eczema) and we assist in the diagnosis and management of
food allergies, which are often seen in children with atopic dermatitis. Together with our pediatric gastroenterologists
at Children’s, we are currently helping diagnose and treat patients with a
severe inflammatory condition of the esophagus called eosinophilic esophagitis
(EoE) that is associated with atopic dermatitis and food allergy. The condition
isn’t as rare as you might think - there are hundreds of these patients in Alabama. EoE is much like eczema of the esophagus. It
is an allergic inflammatory process that causes pain, vomiting and more significantly,
scarring of the esophagus so patients develop strictures or narrowing. This can
cause food to get impacted in the esophagus and lead to a trip to the emergency
room.
There’s much we don’t know about eosinophilic esophagitis.
It is clearly related to hyper-sensitivity or allergy, often to foods. When the
tissue is put under a microscope, it looks a lot like eczema. It’s not a pure
allergic problem, but it has an allergic component. Cow’s milk is often the
culprit.
We have many medications and techniques we can use to treat
all these allergic illnesses. For example, we can provide immunotherapy shots
to reduce a patient’s sensitivity to common aeroallergens such as pollen, house
dust mites and animal dander and to insect stings. The treatment of severe
insect sting allergy of the type that causes anaphylaxis with immunotherapy has
been proven to work in numerous scientific studies, but many people, including those
in the local medical community, are not aware of this important treatment
option.
We’re getting more knowledgeable about how the immune system
works, and many new biologic medical products are now coming onto the market.
The first of these biologics to be approved by the FDA, a monoclonal antibody
called omalizumab, or Xolair, is used in patients with allergic asthma. It’s
moderately effective at blocking the allergic reaction. Unfortunately, it’s
costly, so it’s not something to take for conditions like hay fever, but it
becomes a cost-effective option for patients who have allergic asthma that is
putting them in the hospital every other month.
Often, patients come to us with suspected food allergies,
and right now all we can do is provide them with the right diagnostic testing
and then give advice on how to best avoid their specific allergens – there
aren’t any shots or specific treatments available. Food allergies have proven
extremely difficult to treat, but that may be changing. Research is advancing
into protocols to desensitize patients with these allergies. These treatment
protocols are still being developed but if and when they become approved for
use in dedicated centers, I’d certainly like our clinic to be one of those. For
example, one of the latest studies shows that patients with severe peanut
allergies may never get to the point where they can eat a bag of peanuts, but
they may be able to safely eat a single peanut, which is sufficient to keep
them from having a severe allergic reaction from an accidental exposure.
Of course, all these new treatments require a high degree of
specialized skill. Our specialists are certified by the American Board of
Allergy and Immunology. That means spending at least two years in a
subspecialty program with a highly defined and monitored training curriculum to
learn how to practice clinical allergy and immunology. This rigorous training
is capped by a difficult examination. All graduates since 1990 have been
required to participate in maintenance of certification to ensure continuing
expertise with new medical discoveries.
For more information about our program or allergies in
general, visit www.childrensal.org/allergyimmunology.
We have excellent content on the site specifically designed for children, teens
and parents.
Dr. Prescott Atkinson
is Director of Pediatric Allergy and Immunology at Children’s of Alabama and a
Professor of Pediatrics at UAB. He is board certified in pediatrics, as well as
pediatric allergy and immunology. He received his MD/PhD from Emory University
in 1987, completed his pediatric residency at Georgetown University, and
completed a fellowship in allergy and immunology at the National Institutes of
Health in 1992. He joined the faculty at UAB that year.

Weight Loss Surgery – Standing out from the Crowd
By: Sue Bunnell, RN and Clinical Manager of the Princeton Comprehensive Bariatric Center
I came to Princeton Baptist Medical Center in March of
2010. But it was a homecoming for
me. I had been part of the Baptist
family since 1998-2005. I was asked to
help transform our Surgeon’s vision into 4 walls, and this is our story.
TO
ACCOMPLISH OUR MISSION, Princeton Baptist Health System’s Bariatric Team will:
- Strive to ensure that each patient
is fully informed, fully prepared and their expectations have been met
- Provide a safe and comfortable
environment for each and every patient that is cared for within our
facility
- Be committed to treating all
patients with the utmost respect and dignity
- Offer preoperative and
postoperative nutritional and exercise counseling
- Facilitate support group meetings
twice per month
- Provide a complete and
comprehensive educational experience to patients wishing to learn about
the surgical treatment of morbid obesity and out program
- Provide a comprehensive surgical
experience for patients who choose to proceed with Roux-en-Y, adjustable
gastric banding or sleeve Gastrectomy
- Develop an after-care program to
assist the weight loss surgery patient throughout their journey
Now, let me tell you about the structure, or what you will
see. We are a 6200 square foot area,
custom designed for the person of size.
When you first enter our Center, you will notice, things are different
here. I will echo that, with a hearty, “Yes,
they certainly are”.
As you begin your look around, you will notice the size
appropriate chairs. These are a custom
designed product. The changes from the intended
creation were recommendations by our patients to enhance comfort.
You will also notice randomly spaced seating throughout our
facility. This is from the valet parking
area to our auditorium. We want you to
be comfortable in knowing that we understand that you may struggle walking long
distances at a time. The
hallways are adequate for a power chair and a care partner to enter
together. We are here for you, and ready
to accommodate your needs!
Speaking of hallways, we have one with a special title. It is the “Because I can” wall. We ask patients to bring in photos of various
things that represent non-scale victories.
Quality of life is so much more than a number on a scale or “high school
skinny”. It is all about moving off of
the side lines and into the game.
The next area of interest is our gym. It provides an intimate area with 6 machines
(all weight rated at minimum of 450 pounds), medicine balls, hand weights and
kettle bells. One of our machines can be
configured to accommodate a wheel chair.
Our gym area is very private. All
of our pre-operative patients will receive an orientation class to the exercise
equipment. The goal is to help our
patients’ feel comfortable enough in the gym environment to transition into a
public gym. We want to help cultivate a
lifelong love of exercise.
Toward the back of the facility, we have a wonderful area
designed just for socializing. There are
several intimate seating areas for friends to gather. Public computers are part of this area even
though we have free Wi-Fi. The
educational experience is so important to our patients whether they are seeking
to learn more about surgical options or connect with other patients. We want to support them through all steps of
their journey.
The largest area in our facility is the 1700 square foot
auditorium. This room ROCKS! Literally, as we have surround- sound, LCD
projector, big screen, etc. We are even
equipment with an air-conditioning unit specific to this meeting room. We are fully equipment to educate. We can
seat a little over 100 people for meetings.
We conduct seminar for the patient seeking information about surgery,
support group, educational classes as well as Zumba, Yoga and Walking class all
within these four walls. A big favorite
is the portable cook top that is located in the front of the room. We have a kitchen on wheels! We provide a cooking demonstration with lunch
the third Friday of each month. It has
been very well received by our surgery patients as well as other visitors to
the Center. Mr. John Naro, Executive
Chef, for Princeton hospital is the guest speaker for this event.
We have a bimonthly support group led by our very own
Certified Life Coach, Stefanie Dutton.
She works very hard to keep the topics fresh and original. She has various guest speakers come to share
information. She provides printed
educational material for future reference.
We have just introduced a Recovery Program. This program has been specifically written
for those who have had weight loss surgery and have experience inadequate
weight loss, or weight regain. We
provide compassionate care, in a nonjudgemental surrounding. We help you work through the issues, set
goals, and start making changes to find success. This is also multidisciplinary with monthly
classes, use of the gym and a $40.00/month fee.
OK – I have been speaking in great length about those
interested in the surgical weight loss options.
We here at the Comprehensive Bariatric Center understand that surgical
intervention is not the choice for everyone.
We also support a medical weight management program. It is a multidisciplinary approach with
monthly meetings, usage of the gym, and support group. There is a $40.00/month fee attached to this
program.
This same program can be utilized to accommodate the 7 month
physician monitored weight loss requirement that is required by some
insurance. We coordinate your care with
your primary care physician and the surgeons’ office.
Moving to a more personal note, I am a weight loss surgery
patient. I had RNY 9 years ago. My highest weight was 293 pounds. I was on 13 prescription medications for
various health conditions. Currently I
am sporting a 145 pound weight loss, and all of my health conditions are in
remission. So, when I tell you that I
know the feelings of anxiety, fear, frustration, hopelessness and pain
associated with obesity, please be assured that I really know.
God Bless,
Sue

Living with Psoriasis
By: Dr. James Krell with Total Skin and Beauty Dermatology Center
Psoriasis can start at any age, but the most common age of onset is in the mid-20s. The cause of psoriasis is unknown, but about 30% of patients have inherited it from one of their relatives. The most common type of psoriasis is plaque psoriasis, but a frequent type of psoriasis is called guttate psoriasis and occurs in young people (often under the age of 20) as a result of a strep infection.
Psoriasis is frequently associated with itching and can often affect daily life activities such as walking (especially when it is on the feet), standing or sitting for long periods of time, sleeping and even one’s sexual life.
There is also a strong association with depression, and about 30% of patients with psoriasis have a type of arthritis called psoriatic arthritis that is associated with pain and swelling of the feet, fingers, wrists and back. It is also associated with stiffness in the morning.
Recent studies have shown that psoriasis is associated with a higher risk of cardiovascular disease. This data comes from several sources, but the main source is the large database in the United Kingdom.
The cardiovascular risk is highest in patients who are young and have severe psoriasis. Nonetheless, the risk exists in all patients with psoriasis. Dermatologists continue to ask the question as to whether treating the psoriasis reduces the cardiovascular risk in those patients.
A study of 2,400 patients in Denmark published in 2012 begins to answer that question. In the study, the authors found that patients who were treated with biologic medications (Enbrel, Humira, Stelara) and Methotrexate had a lower incidence of stroke, heart attack and death.
We recommend that all patients with psoriasis have a primary care doctor who can look at their cardiovascular health on a regular basis. We suggest reducing cardiovascular risk factors when possible. In particular, we suggest weight loss and that patients not smoke.
At Total Skin & Beauty, we treat psoriasis aggressively in our practice with phototherapy, topical therapy, laser therapy, oral medications and new biologic injectable medications to get most patients’ disease under good control.
Dr. Krell is considered to be a national expert on psoriasis and has lectured extensively in the United States and internationally on this frustrating disease.

Glaucoma – the “sneak thief” of sight
By: Leo
Semes, OD _ Professor, UAB School of Optometry.
You may have seen recent headlines about
glaucoma awareness. Prevent Blindness
America, whose mission is to educate the public about causes of blindness,
glaucoma being the second-leading cause in the USA, has this resource. (http://optometrytimes.modernmedicine.com/optometrytimes/news/prevent-blindness-declares-january-national-glaucoma-awareness-month; accessed
January 8, 2014). Diagnosis of glaucoma
often is delayed due to the fact that is typically symptomless for vision loss
until significant damage had occurred, hence the awareness campaign
In a larger sense, the World
Glaucoma Association is campaigning globally the World Glaucoma Week 2014, “BIG
– beat invisible glaucoma.” Celebrated
March 9-15 this year, this clever slogan is a reminder to all that glaucoma is
often a symptomless and painless disorder that can lead to blindness. I should know, my mother was diagnosed early
in life with glaucoma, treated and yet lost vision to the disease. Contemporary management of glaucoma has
improved over that past generation and consists of reducing the No. 1 risk
factor – elevated intraocular pressure (IOP).
In fact, the FDA has approved a number of very efficacious topically
applied drops to lower IOP.
Administration is typically once to three times per day which enhances
compliance on the part of the patient as well minimizes side effects.
A positive family history has been
linked to an increased risk of developing glaucoma, along with a number of
additional factors. Studies from the
early 1990s indicated that roughly one-half of glaucoma is undiagnosed. While the prevalence of glaucoma is somewhere
in the neighborhood of 4%, the proportion undiagnosed represents a large number
at risk for vision loss. Unfortunately,
while diagnostic strategies have advanced to uncover early damage over the past
three decades, the undiagnosed percentages remain.
A comprehensive eye examination
includes measurement of IOP. In
addition, suspicion of early damage by observation of characteristic features
of damage or vision loss can prompt definitive testing to confirm or rule out a
diagnosis. Definitive testing includes
direct observation and digital imaging of the optic nerve and retinal nerve
fiber layer as well as a visual field test that measures sensitivity of the
retina and can identify early functional loss.
If glaucoma is identified, new treatment options have shown significant
progress in reducing the likelihood of blindness over a lifetime. So, if you have a family member diagnosed
with glaucoma, see your eye care professional.
UAB Eye Care (205 975-2020) offers comprehensive eye examinations that
include screening for glaucoma as well advanced testing and treatment options
if glaucoma is identified.

Changes to Implementation of Pain Management Provider Registration
by: Kelli Robinson (Kelli is a dual member of both the Health Care Law Consulting Group and the Labor & Employment practice at Sirote.)
On January 17, 2014, the Board announced a modification in its implementation of registration for providers of pain management services. As reported earlier, pain management services are those medical services that involve the prescription of controlled substances in order to treat chronic non-malignant pain by a physician who treats pain. The Board defines the provision of pain management services as:
- A physician practice which advertises or holds itself out to the public as a provider of pain management services; OR
- A physician practice which dispenses opioids; OR
- A physician practice with greater than 50% of the patients being provided pain management; OR
- A physician practice in which any of the providers of pain management services are rated in the top 10% of practitioners who prescribe controlled substances in Alabama, as determined by the Alabama Prescription Drug Monitoring Database on an annual basis.
Until further notice, however, the Board is not requiring the top 10% prescribers to register as providers of pain management services.
All other requirements remain in effect; consequently, physicians must still register with the Board if they are engaged in:- A physician practice which advertises or holds itself out to the public as a provider of pain management services; OR
- A physician practice which dispenses opioids; OR
- A physician practice with greater than 50% of the patients being provided pain management.
The Board also reminds physicians that the requirements for registration are for physicians treating chronic, non-malignant pain, not for physicians who treat acute pain or malignancy-related pain. Additionally, the Board’s registration requirements do not apply to a licensed hospice program or any physician providing pain management services for that program, or to any facility maintained or operated by the United States government.
To help physicians determine whether registration as a provider of pain management services is required, the Board recently published the following questions on its web site:
- Do you treat chronic non-malignant pain? If your answer is NO, you do not need to register as a provider of pain management services. If your answer is YES, please proceed to the following question.
- Do you advertise or hold yourself out as providing treatment for patients with chronic non-malignant pain? If your answer is YES, you should register as a provider of pain management services. If your answer is NO, please proceed to the following question.
- Does the ultimate user (patient) physically leave your medical practice with an opioid? If your answer is YES, you should register as a provider of pain management services. If your answer is NO, please proceed to the following question.
- Do you treat more than fifty percent (50%) of your patients for chronic non-malignant pain? If your answer is YES, you should register as a provider of pain management services.

New Technologies in the In Vitro Fertilization (IVF) Lab
Fortunately, improvements in Assisted Reproductive
Technology for fertility care occur constantly.
In this article we update providers and patients on an important
development which offers the ability to screen the embryo for genetic diseases
carried by the parents and to screen for chromosomal abnormalities in the
embryo.
This will ultimately decrease the miscarriage rate and
increase the chance to have a healthy baby through IVF or Egg Donation. Additionally, 2 new instruments are presented
which allow us to offer improved pregnancy outcomes with IVF and Egg Donor.
Preimplantation
Genetic Screening (PGS) and Diagnosis (PGD) – change in biopsy and transfer
procedures
1.
What
is the difference in Preimplantation Genetic Screening and Preimplantation
Genetic Diagnosis?
Preimplantation Genetic Screening (PGS) and
Diagnosis (PGD) are both used to perform genetic testing on biopsied cells
taken from embryos during an IVF cycle. During PGS, embryos are screened for changes
in chromosome numbers, whether a translocation/inversion or aneuploidy. All 23 pairs of chromosomes may be screened
at one time.
With PGD, embryos may be tested and
diagnosed for a specific disease such as Cystic Fibrosis, Tay-Sachs, or Spinal
Muscular Atrophy. Most genetic diseases
that have been identified by a study of the parents for a gene mutation can be
tested for with PGD.
2.
How
has the procedure changed?
Previously a blastomere was biopsied from a
6 – 8 cell cleavage stage embryo on day 3 of culture and the blastomere was sent
to a diagnostic lab. Results were
received, and 1 - 2 normal embryo(s) were transferred to the patient’s uterus
on day 5 of culture at the blastocyst stage.
Currently, several cells are biopsied from
the 100 or more cell embryos at the blastocyst stage on day 5 of culture. The blastocyst is then cryopreserved with
vitrification and stored until results are received.
The patient then undergoes a frozen embryo
transfer (FET) cycle at her convenience where the normal embryo(s) is warmed
and transferred in an attempt at pregnancy.
3.
What
are the advantages to the new procedure?
Since the blastocyst has many more cells
than the cleavage stage embryo, multiple cells are removed and processed as
compared to 1, sometimes 2, blastomeres.
A larger amount of cells for diagnosis means more accurate results.
Mosaicism is reportedly lower at the
blastocyst stage as compared to the cleavage stage embryo, thereby increasing
the chance that results are representative of the rest of the blastocyst.
Even though each blastomere of a cleavage
stage embryo is totipotent, cells biopsied from the blastocyst are
trophectoderm cells, which are extra-embryonic
tissue, thus the inner cell mass of the blastocyst is not manipulated –
it is this tissue that becomes the baby.
A laser is needed to perform the biopsy on
the trophectoderm cells and is used to prepare the embryo on day 3 of culture. The
laser is much easier to use than the previous methods using mechanical and
chemical means.
Performing the embryo transfer in a non-stimulated
FET cycle may be advantageous as compared to the stimulated IVF cycle.
A higher percentage of patients will
potentially receive a single embryo transfer leading to fewer high-risk
pregnancies.
4.
Will
PGS or PGD increase a woman’s chances of pregnancy?
The chance for delivery of a healthy baby
will be increased with the use of PGD, and will vary with the use of PGS with
each unique situation.
5.
What
does a couple need to know before PGS or PGD is performed?
A couple should make an appointment with
their fertility specialist to discuss PGS or PGD. The process for PGD is more involved than
PGS.
With PGD, a formal consultation with a
genetics counselor is indicated and a customized genetic marker will be
designed by the diagnostic lab prior to the IVF/PGD cycle. A marker is not required for PGS testing.
Should you have questions about PGS or PGD,
please call the ART Fertility Program of Alabama’s scheduling department at
205-870-9784 to schedule an appointment with a physician.
New incubator systems
1.
What
is an incubator?
The incubator is one of, if not the, most
important piece of equipment in the IVF Lab.
The incubator provides a stable environment for the developing embryo
during IVF procedures.
In order to optimize embryo growth and clinical outcome, the incubator functions to control temperature, gas concentrations and humidity, as well as reduce environmental stresses.
2.
How
does the new G185 differ from a typical incubator?
The G185 is smaller and has individual chambers for each patient. Water is not required as the incubator functions without humidity. Gas cylinders are easily connected providing the carbon
dioxide and low oxygen environment
desired. Each chamber contains a
stainless steel plate heated to 37⁰ centigrade.
This creates a compartmentalized system.
1.
Does
the G185 provide a better environment for embryos?
Maintaining the embryos in a more
compartmentalized system provides a better environment by limiting exposure of
embryos to the room environment when entering the chamber and quicker recovery
of temperature, gas concentration and pH.
2.
Will
Art Fertility’s patients benefit from this G185?
Due to the better temperature and gas
stability, along with the compartmentalized, low oxygen environment of the
G185, ART Fertility’s patients will benefit from this new technology.
Thus far we have seen an increase in embryo
quality leading to more embryos available for transfer and vitrification and a
trend towards an increase in pregnancy rates.
New Laser – Saturn
5 by Research Instruments
1.
What
is a laser?
The Saturn Laser uses a high-powered
ablation laser and a visible pilot laser transmitted through fibre optics. The Saturn has sub-micron accuracy with a
computer controlled laser. An Exclusion
ZoneTM ensures safety of the cells by establishing an area of lowest
laser pulse near critical areas.
2.
What
is the laser used for in the IVF Laboratory?
The Saturn Laser is used to introduce an
opening in the zona pellucida (ZP), the outside covering of the embryo. This procedure is referred to as Laser
Assisted Hatching or LAH in lab terms.
LAH may be indicated during an IVF cycle
for the following: advanced maternal age, recurrent implantation failure,
elevated FSH or P4, poor embryo quality including embryos with thick ZP, and
frozen-thawed embryos or oocytes.
Spontaneous hatching of the embryo from the
ZP is a necessary event prior to implantation of the embryo in the uterus.
Creating an opening in the embryo’s ZP is thought to facilitate implantation
for those embryos considered to have trouble implanting due to hardening of the
ZP or lack of spontaneous hatching.
Another use of the laser is to collapse the blastocyst, the 5
or 6 day old embryo, prior to cryopreservation by vitrification. The blastocyst
is characterized by an inner cell mass, the trophectoderm cells, and the fluid
filled blastocoel cavity. By lasering the junction between two trophectoderm
cells, the blastocoel cavity will collapse, causing the fluid to leave the
cavity.
Vitrification has been found to be more successful after
removal of fluid from the blastocyst.
Research has indicated an increase in blastocyst implantation following
laser collapse of the blastocyst prior to vitrification.

What
benefits have you seen from this new technology?
Results with the Saturn Laser thus far in
our program have shown a trend towards a higher implantation and/or ongoing
pregnancy rate when LAH and/or collapsing is utilized.

How
will ART Fertility’s patients benefit from this new laser?
The improvement in implantation and
pregnancy results should allow patients a higher chance to have a baby with
IVF.
At
ART Fertility of Alabama, we are excited about these new additions to our
laboratory. These new developments in Assisted Reproductive Technology for
fertility care will increase the chances to have a healthy baby through IVF or
Egg Donation, and we are thrilled to offer this to our patients.
