When a letter from a therapist doesn’t satisfy WPATH SOC

Saturday, December 12th, 2009

Dear Laurie,

Read the letter and this is the classic example of how a letter of endorsement should not be written. This type of letter is in fact seen when a therapist feels a certain obligation to say something but in fact has deep seated reservations about making any written commitment. This is akin to a “letter of recommendation”  for an employee.   Miss so and so worked in my office from June 1st 1999 to September 5, 2001. (Start, period, end of letter).

This is a more a letter of detachment.

The standards for how a letter should be written if the Dr. is interested are posted on WPATH.   To wit:

 

The Mental Health Professional’s Documentation Letter for Hormone Therapy or Surgery

Should Succinctly Specify:

1. The patient’s general identifying characteristics;

2. The initial and evolving gender, sexual, and other psychiatric diagnoses;

3. The duration of their professional relationship including the type of psychotherapy or

evaluation that the patient underwent;

4. The eligibility criteria that have been met and the mental health professional’s rationale

for hormone therapy or surgery;

5. The degree to which the patient has followed the Standards of Care to date and the

likelihood of future compliance;

6. Whether the author of the report is part of a gender team;

7. That the sender welcomes a phone call to verify the fact that the mental health professional actually wrote the letter as described in this document.  

The organization and completeness of these letters provide the hormone-prescribing physician and the surgeon an important degree of assurance that mental health professional is knowledgeable and competent concerning gender identity disorders.

More or less in the first paragraph the therapist should introduce him/herself by virtue of their background and training and societal memberships. Next the therapist should endorse the client for transgender surgery (”I recommend, I endorse, or Miss so and so would be a good candidate for transgender surgery, etc”).

Next suicidal ideation or attempts (yes or no) should be mentioned, as well as any drug abuse history or ethanol dependency (yes or no).

Lastly the therapist should invite the recipient to call their office for further discussion should questions arise.

Look at Dr. Mora’s letter hopefully and you will see the difference.

Sincerely,

Harold M. Reed, M.D.

Tissue Engineering Advance: Implications For FtM Phalloplasty

Linköping, Sweden. Scientists can now create cartilage, bones and the internal walls of blood vessels by using common connective tissue cells from human skin. Researchers in reconstructive plastic surgery at Linköping Universitet successfully manipulated these tissue cells to take on different shapes depending on the medium used for cultivation.

This is a practical example of an autologous biological process, where cells, tissues or even proteins can be reimplanted in the same individual who donated the materials in the first place. Candidate materials for autografts ordinarily include a variety of natural donor sites, including bone, bone marrow, cartilage, and skin biopsy.

There are obvious implications for generating new and improved techniques for Sex Reassignment Surgery (SRS), including phalloplasty, a continuing issue for F2M patients (cf. sidebar).

Phalloplasty is the construction or repair of a penis. In natal males, it can involve modification of an existing penis to correct the effects of an injury or to achieve cosmetic goals. Dr. Harold Gillies performed the first phalloplasty for FtM sex reassignment on Michael Dillon in 1946, a story documented in The First Man-Made Man by Pagan Kennedy.

In general, the sex organs of natal males and females evolve from the same human tissue. For instance, the glans penis is made of the same basic material as the clitoral glans (i.e., they are homologous). Likewise, the male corpora cavernosa are homologous to the clitoral body. Among other examples are the pairings of corpus spongiosum/vestibular bulbs (beneath the labia minora) and the foreskin/clitoral hood. The scrotum is homologous to the labia minora/majora.

Because of these homologous relationships, the combination of hormone therapy and surgical intervention offers opportunities for effective transformation. Over the long term, natural tissue replacement in the body (under hormonal supervision) enhances the outcome.

Basic surgical procedures are similar ro those used on natal males (except in extreme cases). The labia are united to form a scrotum capable of housing prosthetic testicles. However, the urethra must be lengthened since it ends near the vaginal opening, a source of many (if not most) surgical complications.

Sexual penetration is possible following the replacement of the erectile tissue with an erectile prosthesis. Ordinarily, this is done as a separate surgery to reduce risks and promote healing.

Historically, phalloplasty techniques included grafts from the arm, leg, abdomen or musculocutaneous latissimus dorsi, replanting abdominal muscle, or relocating fatty tissue from the abdomen.Another important technique has been the insertion of living bone (long-term follow-up studies in Germany and Turkey show that stiffness is maintained without late complications.

A more contemporary option is metoidioplasty involves enlarging the preexistent clitoris by hormone replacement therapy and fashioning a small penis that can be enlarged using other techniques.

Surgical techniques for FtM patients have advanced since the first phalloplasty, but much remains to be done. This situation is changing with new research efforts and the arrival of practical techniques derived from bioengineered tissue cultures.
Bone, cartilage and blood vessels are important components in reconstructive surgery, when damaged or missing tissue needs to be recreated. Minor fractures can heal spontaneously but for major bone damage and cartilage injuries there is the need to transplant tissue from other parts of the patient’s body.

The studies are the first in the world with results that show connective tissue cells from human skin transformed into other so called phenotypes and creating other types of tissue. Previously, researcher have attempted to grow autologous tissue from stem cells, such as those present in bone marrow. These cells, however, can be difficult to harvest, cultivate and store.

Connective tissue cells from human skin have great comparative advantages. A small biopsy is often sufficient to collect a useful number of cells.

Gunnar Kratz is a Professor of Experimental Plastic Surgery and team leader for the research group. “This means that it will be much easier to produce autologous tissue, which is tissue created from the patient’s own body”, he says. The results of the group’s research are now published in three simultaneous scientific articles. [C1-3]

According to Kratz, connective tissue cells “… are the `weed’ cells of the body, very easy to collect and cultivate into the cell type required. They are also very suitable to use to create a personal cell bank.”

Working with colleagues, Kratz has developed a technique to grow bone-like, cartilage-like and endothelial-like cells from connective tissue cells. Endothelial cells are the building blocks for the inner walls of blood vessels and line the entire circulatory system, reducing the turbulence of blood flow and allowing further pumping of blood fluids.

The new technique has been used to create whole tissue in gelatine scaffolds. Currently, preparations are underway to transplant these complete tissue pieces into laboratory animals.

In the their studies, the researchers collected connective tissue cells from healthy skin left over from breast and stomach plastic surgery and used fat stem cells to provide a comparison. To ensure that the transformation was not a result of the fusion of different cells, connective tissue cells from one cloned cell were also used.

The cell cultures were cultivated in four different environments optimised for
bone,

cartilage,

fat and

endothelium.
After two to four weeks the connective tissue cells had produced cartilage and bone mass to a greater extent than the fat stem cells had. The cells showed
several functions normally only present in the genuine (or conventionally ocurring) cell type.

capabilities as building material for three dimensional tissues, to create capillary networks, and other functions important to regenerative medicine.
“The dream is to be able to manipulate connective tissue cells in the human body to develop into specific cell types, for example to create bone cells for broken bones”, says Kratz. And much more.

Summary

The creation of tissue-engineered cartilage and bone, using cells from an easily available source seeded on a suitable biomaterial, may have a vast impact on regenerative medicine. While various types of adult stem cells have shown promising results, their use is accompanied by difficulties associated with harvest and culture. The proposed inherent plasticity of dermally derived human fibroblasts may render them useful in tissue-engineering applications. In the present study, human dermal fibroblasts cultured on macroporous gelatine microcarriers encapsulated in platelet-rich plasma into three-dimensional constructs were differentiated towards chondrogenic and osteogenic phenotypes using specific induction media. The effect of flow-induced shear stress on osteogenic differentiation of fibroblasts was also evaluated. The generated tissue constructs were analysed after 4, 8 and 12 weeks using routine and immunohistochemical stainings as well as an enzyme activity assay. The chondrogenic-induced tissue constructs were composed of glycosaminoglycan-rich extracellular matrix, which stained positive for aggrecan. The osteogenic-induced tissue constructs were composed of mineralised extracellular matrix containing osteocalcin and osteonectin, with cells showing an increased alkaline phosphatase activity. Increased osteogenic differentiation was seen when applying flow-induced shear stress to the culture. Un-induced fibroblast controls did not form cartilage- or bone-like tissues. Our findings suggest that primary human dermal fibroblasts can be used to form cartilage- and bone-like tissues in vitro when cultured in specific induction media.

Depth now or later, Mr. Right

Sunday, December 6th, 2009

Can depth be added later on.  Now feel very asexual.

 Rundle

 

Our “party line” to all patients unless they insist, is go for depth as part of the original plan when you have vaginoplasty. This means if you need a scrotal graft, by all means this is the perfect time to do that. But you do have a responsibility to dilate to maintain depth and width, and even build upon that.

I have seen many patients acquire an additional 2 inches simply by using stents for 15 minutes with gentle pressure 5 or more times a day.

You never know when Mr. Right will come along and turn your latency upside down and re kindle all the loving and bonding mechanisms that nature has given you. They were there from the outset
but just dormant and maybe uneven suppressed for one reason or another. Yes, I also believe that female preference is a mentally acceptable expression, as does the American Psychiatric Association, however, this way you are ready.
