RESEARCH OBJECTIVES

Background

Although a number of focal pain syndromes of the urogenital area have been
well described, they remain underrecognized and poorly understood. 
Vulvodynia, one of the types of focal pain syndromes in the female, is a
complex, multifactorial, underdiagnosed clinical syndrome of unexplained
vulvar pain, sexual dysfunction and psychological disability.  An earlier
controversy surrounding this group of disorders ranged from opinions
questioning their existence to suggestions that they were of a purely
psychosomatic origin. More recently, this has been largely counterbalanced by
an extensive recent literature attesting to the organic nature of these
disorders.  At present, neither the prevalence nor the etiology of this
enigmatic condition is accurately known.  A specific secondary cause can
usually be diagnosed in only a small minority of the patients experiencing the
symptoms of vulvodynia. Only empirical treatment options are available at
present.  While cures are uncommon, some measure of pain relief can be
achieved in nearly all patients using a multidisciplinary approach involving
pain medications, local treatment regimens, physical therapy and psychological
support.  Medical management usually employs medication protocols designed to
treat neuropathic pain and has been under-investigated to date.  Pain
management techniques such as biofeedback and behavior therapy have been
reported in some instances to provide positive outcomes.  Surgery involving
invasive and often irreversible therapeutic procedures has been stated,
arguably, to be the treatment option with the highest success rate for certain
subtypes of vulvodynia.

Vulvar pain syndrome (vulvodynia, burning vulvar syndrome) was first described
as a syndrome at the end of the last century.  Although more than a hundred
years have passed in the interim, the cause(s) of the disorder remain(s)
undiscovered.  Several subtypes of vulvodynia have, however, now been
recognized and identification of the distinct subset of patients presenting
with vulvodynia has been stated to be a prerequisite for its successful
management.  The most common subtypes recognized are vulvar vestibulitis
syndrome, cyclic vulvovaginitis,and dysesthetic vulvodynia.  Vulvar
vestibulitis, thought to be the major subtype of vulvodynia, has been found in
some studies to be present in as many as 15% of patients in a general clinical
practice.  Vulvar vestibulitis syndrome (VVS) characterized by severe, chronic
pain on vestibular touch or attempted vaginal entry is thought to be the most
frequent cause of dyspareunia in premenopausal women.  Other frequently
misdiagnosed vulvar or vaginal conditions which can also cause vulvodynia are
vulvar papillomatosis, cytolytic vaginosis, lactobacillosis, and desquamative
inflammatory vaginitis.  In addition, many vulvar dermatoses can cause acute
or chronic vulvar itching or pain, and are a frequent confounding problem in
the differential diagnosis of vulvodynia.  While studies have been reported
that describe the histological abnormalities observed in patients with vulvar
vestibulitis as the result of a chronic inflammatory reaction of the mucosa of
the vulvar vestibule, the cause of the latter remains unclear.  Reports
proposing a clinical role of urinary oxalates as nonspecific irritants,
contact allergy, candidiasis or human papilloma virus (HPV) infection in women
presenting with vulvodynia remain without consensus and are controversial.

Scope

Systematic epidemiologic, etiologic, and therapeutic studies of vulvodynia
should be undertaken to better define its prevalence, establish diagnostic
criteria for discriminating between its major and minor subtypes, elucidate
its underlying pathophysiology, clarify its mechanism of pain and develop
improved clinical therapy options designed to either cure it or alleviate its
symptoms.

Examples of hypothesis-driven research approaches that are encouraged include,
but are not limited to:

o  Conducting experimental preclinical or clinical studies in animals and/or
humans, respectively, designed to evaluate the presence and extent of abnormal
neurophysiological mechanisms that underlie inappropriate sensory and motor
pathway activities associated with vulvar pain.

o  Determining the role of neurogenic inflammation in vulvodynia, including
vulvar vestibulitis.

o  Evaluating whether there is widespread or regional autonomic dysfunction in
patients presenting with vulvar pain.

o  Developing chronicity and inclusion/exclusion features/factors as criteria
for refining the definition for and diagnosis of vulvodynia and its subtypes.
A rigorous definition will permit uniform study design leading to
comparability at the national and/or international levels of study.

o  Carrying out population-based epidemiology studies to define the prevalence
of vulvar vestibulitis and other subtypes of vulvodynia. Conducting case
controlled epidemiological studies to determine if a group at high risk of
vulvodynia can be identified for prospective or interventional studies.
Accomplishing population-based epidemiology studies that include psychological
measures useful in defining the psycho-social component of vulvodynia.

o  Conducting well-controlled clinical studies of therapeutic protocols for
treating vulvodynia in a well-defined population with rigorous
inclusion/exclusion enrollment criteria. Studies might include multi-
disciplinary therapeutic trial designs involving medication, aerobic exercise,
and cognitive behavioral therapy. For vulvar vestibulitis only, the use of
surgical procedures for treating this disorder might be explored,  especially
with regard to both the roles of pre- and post- surgical interventions and
surgical therapy outcomes.

o  Defining the vaginal microflora in patients with vulvodynia, including the
role of past or present candidiasis, bacterial vaginosis, trichomoniasis,
gonorrhea, chlamydia, Herpes Simplex Virus (HSV) and/or Human Papilloma Virus
(HPV) colonization or infection.

INCLUSION OF WOMEN AND MINORITIES IN RESEARCH INVOLVING HUMAN SUBJECTS

It is the policy of the NIH that women and members of minority groups and
their subpopulations must be included in all NIH supported biomedical and
behavioral research projects involving human subjects, unless a clear and
compelling rationale and justification is provided that inclusion is
inappropriate with respect to the health of the subjects or the purpose of the
research.  This policy results from the NIH Revitalization Act of 1993
(Section 492B of Public Law 103-43).

All investigators proposing research involving human subjects should read the
"NIH Guidelines For Inclusion of Women and Minorities as Subjects in Clinical
Research," which have been published in the Federal Register of March 28, 1994
(FR 59 14508-14513) and in the NIH Guide for Grants and Contracts, Volume 23,
Number 11, March 18,1994.

Investigators also may obtain copies of the policy from the program staff
listed under INQUIRIES. Program staff may also provide additional relevant
information concerning the policy.

NIH POLICY AND GUIDELINES ON THE INCLUSION OF CHILDREN AS PARTICIPANTS IN
RESEARCH INVOLVING HUMAN SUBJECTS

It is the policy of NIH that children (i.e., individuals under the age of 21)
must be included in all human subjects research, conducted or supported by the
NIH, unless there are clear and compelling scientific and ethical reasons not
to include them.  This policy applies to all initial (Type 1) applications
submitted for receipt dates after October 1, 1998.

All investigators proposing research involving human subjects should read the
"NIH Policy and Guidelines on the Inclusion of Children as Participants in
Research Involving Human Subjects" that was published in the NIH Guide for
Grants and Contracts, March 6, 1998, and is available at the following URL

REVIEW CONSIDERATIONS

Applications will be assigned on the basis of established Public Health
Service referral guidelines.  Applications will be reviewed for scientific and
technical merit by study sections of the Center for Scientific Review (CSR),
in accordance with the standard NIH peer review procedures.  As part of the
initial merit review, all applications will receive a written critique and
undergo a process in which only those applications deemed to have the highest
scientific merit, generally the top half of applications under review, will be
discussed, assigned a priority score, and receive a second level review by the
appropriate national advisory council or board.

Review Criteria

The goals of NIH-supported research are to advance our understanding of
biological systems, improve the control of disease, and enhance health.  The
reviewers will comment on the following aspects of the application in their
written critiques in order to judge the likelihood that the proposed research
will have a substantial impact on the pursuit of these goals.  Each of these
criteria will be addressed and considered by the reviewers in assigning the
overall score weighting them as appropriate for each application.  Note that
the application does not need to be strong in all categories to be judged
likely to have a major scientific impact and thus deserve a high priority
score.  For example, an investigator may propose to carry out important work
that by its nature is not innovative but is essential to move a field forward.

1.  Significance.  Does this study address an important problem? If the aims
of the application are achieved, how will scientific knowledge be advanced? 
What will be the effect of these studies on the concepts or methods that drive
this field?

2.  Approach.  Are the conceptual framework, design, methods, and analyses
adequately developed, well-integrated, and appropriate to the aims of the
project?  Does the applicant acknowledge potential problem areas and consider
alternative tactics?

3.  Innovation. Does the project employ novel concepts, approaches or methods? 
Are the aims original and innovative? Does the project challenge existing
paradigms or develop new methodologies or technologies?

4.  Investigator. Is the investigator appropriately trained and well suited to
carry out this work?  Is the work proposed appropriate to the experience level
of the principal investigator and other researchers (if any)?

5.  Environment. Does the scientific environment in which the work will be
done contribute to the probability of success?  Do the proposed experiments
take advantage of unique features of the scientific environment or employ
useful collaborative arrangements? Is there evidence of institutional support?

The initial review group will also examine: the appropriateness of the
proposed project budget and duration; the adequacy of plans to include (or
justifications for not including) both genders, minorities and their
subgroups, and children as appropriate for the scientific goals of the
research and plans for the recruitment and retention of subjects; the
provisions for the protection of human and animal subjects; and the safety of
the research environment.

AWARD CRITERIA

Applications will compete for available funds with all other approved
applications. The following will be considered in making funding decisions:
Quality of the proposed project as determined by peer review, availability of
funds, and program priority.
