Honestly, I have never noticed Curcumin on any of my patients’ lists of pharmaceuticals or supplements, but I will be certain to look for it now. Curcumin is the fat-soluble molecule that gives turmeric its yellow pigment, and it is best absorbed with the addition of black pepper extract. Patients often complain non-steroidal anti-inflammatory medicines (NSAIDs) tear apart their stomachs, so newer studies showing positive results with the use of an herb sound promising, even for pelvic health.
A 2015 study by Kim et al. researched the inhibitory effect of curcumin on benign prostatic hyperplasia induced by testosterone in a rat model. Benign prostatic hyperplasia (BPH) is common among men and has a negative impact on the urinary tract of older males. Steroid 5-alpha reductase converts testosterone into dihydrotestosterone (DHT), and this increases as men age and may have negative effects on the prostate gland. Because of the side effects of conventional drugs (like finasteride) to inhibit steroid 5-alpha reductase, the authors wanted to determine if curcumin could play a protective role in BPH. They divided 8 rats into 4 groups after removal of testicles: 1) normal, 2) BPH testosterone induced subcutaneously, 3) daily curcumin (50mg/kg orally), and 4) daily finasteride (1mg/kg orally). The group receiving curcumin had significantly lower prostate weight and volume than the testosterone induced BPH group, and curcumin decreased the expression of growth factors in prostate tissue. The authors conclude curcumin may be a useful herb in inhibiting the development of BPH with fewer side effects than conventional drugs.
In the urology realm, Cosentino et al.2016 explored the anti-inflammatory effects of a product called Killox®, a supplement with curcumin, resveratrol, N-acetylcysteine (NAC) and zinc. When benign prostatic hyperplasia (BPH) is not treated with drugs, a surgical intervention can be executed called a transurethral resection of the prostate (TURP); or, for bladder cancers, a transurethral resection of the bladder (TURB) can be performed. Either surgery generally requires administration of NSAIDs post-operatively for inflammation, urinary burning, or bladder spasms or to prevent later complications such as urethral stricture or sclerosis of the bladder neck. This open controlled trial involved Killox® tablet administration to 40 TURP patients twice a day for 20 days, to 10 TURB patients twice a day for 10 days and to 30 BPH patients who were not suited for surgical intervention once a day for 60 days. The control group received nothing for 1 week post-surgery, and 52.5% of TURP and 40% of TURB patients required NSAIDs to treat burning and inflammation the following 7 days. None of the Killox® treatment groups had post-operative or late complications except one, and none suffered epigastric pain like those using NSAIDs. The authors concluded Killox® had significant positive anti-inflammatory and analgesic effects on the patients and could be used as a safe alternative to NSAIDs by physicians.
Although “just” an herb, the use of curcumin should be supervised by a healthcare professional who understands proper dosage and any possible contraindications for a particular individual. The curcumin needs to be in a form that can be easily digested and used effectively by the body. Ultimately, it is exciting to learn about an alternative to gut-wrenching NSAIDs, making curcumin a noteworthy anti-inflammatory option for patients.
Nutrition plays an important part in patient wellness and rehabilitation. There are many reasons to consider diet when designing treatment regimens and you can learn all about them in Megan Pribyl's Nutrition Perspectives for the Pelvic Rehab Therapist course. Your next chance to take this course is March 31 - April 1, 2017 in White Plains, NY. Don't miss out!

We are all familiar with the old saying, “You are what you eat.” A functional medicine lecture I attended recently at the Cleveland Clinic explained how chronic pain can be a result of how the body fails to process the foods we eat. Patients who just don’t seem to get better despite our skilled intervention make us wonder if something systemic is fueling inflammation. Even symptoms of vulvodynia, an idiopathic dysfunction affecting 4-16% of women, have been shown to correlate to diet.
In a single case study of a 28 year old female athlete in Integrative Medicine (Drummond et al., 2016), vulvodynia and irritable bowel syndrome (IBS) were addressed with an elimination diet. After being treated by a pelvic floor specialist for 7 months for vulvodynia, the patient was referred out for a nutrition consultation. Physical therapy was continued during the vegetarian elimination diet. In the patient’s first follow up 2 weeks after starting eliminating meat, dairy, soy, grains, peanuts, corn, sugar/artificial sweeteners, she no longer had vulvodynia. The nutrition specialist had her add specific foods every 2 weeks and watched for symptoms. Soy, goat dairy, and gluten all caused flare ups of her vulvodynia throughout the process. Eliminating those items and supplementing with magnesium, vitamin D3, probiotics, vitamin B12, and omega-3 allowed the patient to be symptom free of both vulvodynia and IBS for 6 months post-treatment.
On the more scientific end of research, Vicki Ratner published a commentary called “Mast cell activitation syndrome” in 2015. She described how mast cells appear close to blood vessels and nerves, and they release inflammatory mediators when degranulated; however, mast cell activation syndrome (MCAS) involves mast cells that do not get degranulated properly and affect specific organs like the bladder. She proposed measuring the number of mast cells and inflammatory mediators in urine for more expedient diagnosis of interstitial cystisis and bladder pain syndrome.
Sigrid Regauer’s correspondence to Ratner’s article followed in 2016 relating MCAS to bladder pain syndrome (BPS), interstitial cystitis (IC), and vulvodynia. He described vulvodynia as a pain syndrome with excessive mast cells and sensory nerve hyperinnervation, often found with BPS and IC. The vulvodynia patients had mast cell hyperplasia, most of which were degranulated, and 70% of the patients had comorbidities due to mast cell activation such as food allergies, histamine intolerance, infections, and fibromyalgia.
Considering the association between mast cells and acute inflammatory responses and how mast cells release proinflammatory mediators, it makes sense that dysfunctions such as vulvodynia as well as IC and BPS can result from an excessive amount and dysfunctional granulation of mast cells. Enhanced activation of mast cells causes histamine release, stimulating peripheral pain neurotransmitters (Fariello & Moldwin 2015). If medication and therapy do not solve a patient’s pain, perhaps eliminating the consumption of inflammatory foods could positively affect the body on a cellular level and relieve irritating symptoms of vulvodynia. Pardon the parody, but patients on the brink of being “insane in the brain” from vulvodynia will likely try anything to resolve being “inflamed in the membrane.”

Appropriate sun exposure and/or daily supplements provide our bodies with sufficient amounts of Vitamin D. I would venture to guess almost every one of the patients I treated in Seattle had a deficiency of Vitamin D if they were not taking a supplement. Running outside year round has always kept my skin slightly tan and my levels of Vitamin D healthy; however, when I was pregnant in the Pacific Northwest, I had to supplement my diet with Vitamin D, which was a first for this East Coast beach girl. The benefit of Vitamin D has spread beyond just bone health, with studies showing its impact on pelvic floor function.
Parker-Autry et al., (2012) published a study discerning the Vitamin D levels in women who already presented with pelvic floor dysfunction versus “normal” gynecological patients. The retrospective study involved a chart review of 394 women who completed the Colorectal Anal Distress Inventory (CRADI)-8 and the Incontinence Impact Questionnaire (IIQ-7). These women all had a total serum 25-hydroxy Vitamin D [25(OH)D] drawn within one year of their gynecological visit. The authors defined a serum 25(OH)D of <15ng/ml as Vitamin D deficient, between 15-29ng/ml as Vitamin D insufficient, and >30ng/ml as Vitamin D sufficient. In the pelvic floor disorder group comprised of 268 women, 51% were found Vitamin D insufficient, 13% of whom were deficient. The CRADI-8 and IIQ-7 scores were noted as higher among the Vitamin D insufficient women. Overall, the mean 25(OH)D levels in the women without pelvic floor issues were higher than those who presented with pelvic floor disorder symptoms.
Another case-control study in 2014 by Parker-Autry et al., focused on the association between Vitamin D deficiency and fecal incontinence. They considered 31 women with fecal incontinence versus a control group of 81 women without any pelvic floor symptoms, looking at serum Vitamin D levels. The women with fecal incontinence had a mean serum Vitamin D level of 29.2±12.3 ng/ml (insufficient/deficient), while the control group had a higher mean level of 35±14.1 ng/ml (sufficient). The women completed the Modified Manchester Health Questionnaire and the Fecal Incontinence Severity Index, and women with deficient Vitamin D scored higher on the questionnaire, indicating fecal incontinence as a burden on quality of life. The severity scores were higher for Vitamin D deficient women, but there was not a statistically significant difference between the groups. Once again, the pelvic floor disorder and Vitamin D deficiency correlation prevailed in this study.
An even more recent study looked at postmenopausal women and Vitamin D deficiency (Navaneethan et al., 2015). This prospective case control study involved 120 postmenopausal women, 51 of whom had pelvic floor disorders. The serum 25-hydroxy Vitamin D levels were obtained, and the results revealed a deficiency in those women with pelvic floor dysfunction. Vitamin D levels were found to be significantly lower in women who were 5 years or more into menopause. Overall, Vitamin D was deemed a worthy factor to consider in the pelvic floor disorder population as well as in postmenopausal women.
Taking time to talk to patients about their lifestyle, daily supplements, and diet can often shed light on their ability to benefit from our treatments. If a Vitamin D deficiency sounds possible, discuss current research with them and suggest they get their serum Vitamin D levels checked. Don’t underestimate the power of a little sunshine – it just might have a positive impact on pelvic floor health.

The American Society of Clinical Oncology convened their 2016 annual meeting over the weekend, and several of the presentations suggest new methods of preventing breast cancer recurrence.
Breast cancer patients who are treated with aromatase inhibitor therapy are generally prescribed the the estrogen drugs for a five year course. A new study has suggested that by doubling the length of hormone therapy, the recurrence rate for breast cancer survivors drops by 34%. The study included 1,918 women who underwent five years of hormone therapy with the drug letrozole. After five years, half of the group switched to a placebo while the other half were given an additional five year treatment.
The Univerisity of Pennsylvania School of Medicine has published results from two recent studies which document the effects of Metformin, a drug commonly used to treat type 2 diabetes, on breast cancer and endometrial hyperplasia. The study tracked outcomes for 1,215 patients who were diagnosed and surgically treated for breast cancer. Patients who began to use metformin after their diagnosis were found to have a 50% higher survivability rate than those who did not use metformin.
The timing of metformin use is extremely important when it comes to breast cancer survivability rates. The study also found that patients who used metformin prior to their diagnosis were more than twice as likely to die than those who never used the drug.
A study has indicated that a diet rich in vegetables, fish, and olive oil may decrease the odds of a breast cancer survivor experiencing a relapse or recurrence of their cancer. The study tracked 300 women with early-stage cancer and found that those who ate a normal diet were more likely to experience a breast cancer recurrence. The findings build upon previous research which indicated that a Mediterranean diet, and especially extra virgin olive oil, could reduce breast cancer risk by 68%.

When a 472 pound gentleman recently arrived for an evaluation for low back pain, he came to the clinic for me to help him, not deride him about his weight (which he complained all his doctors have already done). He claimed he had lost 120 pounds but gained back 50, and his low back was extremely painful with transitional movements and daily function. Undoubtedly, this man’s body was a battlefield for inflammation, and no matter how much manual therapy or exercise I implemented, nutrition education seemed vital. Instead of just chatting about baseball or the weather, competently sharing what we’ve studied and learned in continuing education courses is warranted in our practice.
In a 2016 review Klek reveals the most current evidence regarding Omega-3 Fatty Acids in nutrition delivered intravenously. Although physical therapists do not decide the ingredients for patients’ parenteral nutrition, the article thoroughly explains the essential benefits of fatty acids. Aside from being important structural components of cell membranes and precursors of prostaglandins and cholesterol, fatty acids regulate gene expression and adjust pathways of cells regarding inflammation and cell-mediated immune responses. Ultimately, fatty acids modulate metabolic processes in the body, whether locally, in a particular region, or at remote sites. Omega-3 fatty acids have been shown to inhibit synthesis of triglycerides by the liver, prevent cardiovascular disease, reduce cancerous cell growth, and even affect the development of rheumatoid arthritis and Chrohn’s disease. This article not only sheds light on parenteral nutrition for post-surgical, oncology, critically ill, and even pediatric patients but also educates the healthcare professional on the impact fatty acids have on the patients we treat.
In 2015, Haghiac et al. performed a randomized double-blind controlled clinical trial to determine if Omega-3 fatty acid supplementation could reduce inflammation in pregnant woman who are obese. Although the study began with 36 subjects in each group, only 24 women in the experimental group receiving 4 capsules a day of Omega-3 fatty acid (total of 2000mg) and 25 of the women taking 4 placebo capsules a day completed the supplementation over the 25 weeks up until delivery. The authors referenced the findings that low grade inflammation becomes exacerbated in obese pregnant women. While an excess of Omega-6 fatty acids practically promotes inflammation via eicosanoid (hormone) production, a healthy balance of Omega-3 fatty acids lessens inflammatory and immunosuppressive eicosanoid production. This study demonstrated an improvement in inflammation in the women who took the Omega-3 fatty acid as evidenced by a decrease in the expression of inflammatory genes in adipose tissue and placenta as well as reduced plasma C-reactive protein (CRP) at delivery.
Being able to control or reduce inflammation on a cellular level through nutrition could promote an exciting cycle of positive events for obese patients. Decreased inflammation in the body could decrease pain, which could allow and even promote increased activity and likely boost metabolism to equip them to battle obesity. The “Nutrition Perspectives for the Pelvic Rehab Therapist” course should spark the interest of any therapist wanting to guide patients not only on movement and function but also on the appropriate nutrition that best facilitates the body’s ability to heal and perform.

In Megan Pribyl’s course on Nutrition Perspectives for the Pelvic Rehab Therapist, she discusses a wide variety of useful topics specific to nutrition and pelvic health. In her lecture on “Nutritional Homeostasis”, Megan counsels against missing an underlying eating disorder when working with a patient who has bowel issues. Work by Abraham and Kellow (2013) is cited, and in their article published in BMC Gastroenterology, the authors concur that many patients who have functional gastrointestinal complaints may also have disordered eating. How then, can we tell these patients apart, and get patients the most appropriate care? First let’s look at their research.
Patients who were admitted to a specialty unit for those with eating disorders in Australia were studied and were found to have conditions such as anorexia nervosa, bulimia nervosa, polycystic ovarian syndrome, treated celiac disease, and treated bipolar depression. All of the 185 patients completed the Rome II Modular Questionnaire to identify symptoms consistent with functional gastrointestinal (GI) dysfunction. They also completed the Eating and Exercise Examination which collected data about behaviors including objective binge eating, self-induced vomiting, laxative use and excessive exercise.
Esophageal discomfort (heartburn and chest pain of non cardiac origin) was associated with excess exercise (more than 5 days/week). Self-induced vomiting was identified primarily in the patients diagnosed with bulimia. One interesting finding the researchers noted is that for patients who have disorder eating, pelvic floor symptoms that are not associated with functional constipation are a prominent feature. This data begs the question, how can we best screen for disordered eating in patients who present with bowel dysfunction that otherwise may fit with the symptoms and presentation of patients who do not have disordered eating?
Our first step may be to include important conditions and symptoms on our written or computer-based intake forms. Is “disordered eating” or bulimia, anorexia-nervosa included on your intake forms for patients? What about symptoms like heartburn, laxative use, or vomiting? (As an important aside, I always remember being surprised by a patient who had urinary incontinence when she told me that she leaked with vomiting. She had gone through a gastric bypass surgery and would vomit several times per week as a reaction to difficulty digesting food. There may be a few good reason therefore to include vomiting on a checklist.) As pelvic rehab providers, we can understand how frequent vomiting may lead to dehydration, intrabdominal and intrapelvic pressure, potential pelvic floor dysfunction, or how disordered eating may lead to other bowel dysfunctions such as constipation and/or fecal incontinence. If we also hold space for eating issues to be a concern, we may find that asking some valuable questions provides more information.

Many therapists start their career feeling a bit intimidated to work with women who are pregnant. A common and understandable concern is that something the therapist will do during examination or treatment may harm the patient. While there are certainly things to avoid when working with a patient who is pregnant there are also many therapeutic strategies that can help a woman thrive during her pregnancy and beyond. When women have pre-existing issues such as a disease or physical challenge, or when she develops an illness during pregnancy, the therapist needs to rely upon more knowledge- this knowledge is something she rarely learns in school, but more likely in continuing education environments. A recent article asked the question “are women getting sicker, and are there more high-risk pregnancies now than ever before?”
Researchers studied trends in maternal morbidity and mortality in the United States in order to answer this question, and the answer is a definitive “yes”. Several studies describe increases in the rates of maternal morbidity, with issues such as cardiac and pulmonary complications, and the severe blood pressure fluctuations associated with eclampsia. Gestational diabetes, and postpartum rates for hemorrhage, perineal lacerations, and maternal infections have also risen. Part of the reason for more women carrying pregnancies more successfully or longer when they are ill may be contributed to newer treatments for conditions such as diabetes, yet this does not explain entirely the increase in maternal morbidity. Increased cesarean births, longer labors with epidural anesthesia, pre-pregnancy obesity, rates of multifetal pregnancies, and the rising age of mothers are other factors to be considered.
The more we know as health care providers about how maternal morbidity affects our rehabilitation efforts, the more we can contribute to a woman’s pregnancy and postpartum health. If you would like to learn more about caring for women during pregnancy and during the postpartum period, Herman & Wallace offers the Pregnancy and Postpartum Series.

Food, at its basic level, provides us with nutrition and sustenance to perform our daily activities. Populations in tune with nature’s cycles of food tend to eat what is available locally based on climate and growth seasons. When societies move beyond simply eating food for energy, but also for flavor, pleasure, and even status, the face of nutrition changes. Whereas some diseases come from a lack of nutrition, many diseases we are faced with in the United States also come from an overabundance of food, with too many calories or too much sugar making up common causes of lack of health. The knowledge within the field of disordered eating is vast, and patients struggling with disordered eating may be fortunate enough to work with a specialist to help recover healthier habits. Even without a diagnosis of disordered eating, many us can identify with unhealthy eating habits, often guided by stress, fatigue, or emotions.
Prior research has studied how we access willpower under different conditions of cognitive stress. In part of this research, participants were given a number to recall (either 2 digits or 7 digits) and then while walking to another location were offered a snack of either fruit salad or chocolate cake. The authors found that the participants who had to recall a 7 digit number more often chose the chocolate cake, leading the researchers to theorize about the role of higher-level processing and making choices. (Shiv et al., 1999) While we may be aware of a tendency to overeat (or make poorer food choices) during times of stress, fatigue, or emotional distress, changing the habits can be very challenging.
Resources that discuss improving our eating choices in the face of “emotional eating” offers many alternatives, or ways to soothe ourselves without eating. In her books about this topic, clinical psychologist Susan Albers offers advice that may be helpful for our own habit building and for offering basic advice for our patients who struggle with the issue. (While offering advice to patients about healthy eating and habits is within our scope of practice, if a patient has need for a referral to a counselor, psychologist, or nutritionist, we can coordinate such a referral with the patient’s primary care provider.) In her book titled “50 More Ways to Soothe Yourself Without Food: Mindfulness Strategies to Cope with Stress and End Emotional Eating”, Dr. Albers offers many strategies for altering our habits. Some of these ideas include using acupressure points, breathing, rituals, self-massage, yoga, writing, dancing, art, tea, or sex to defer ourselves from poor eating habits. While eating can be enjoyable and pleasurable, when our patients are struggling with over-eating or eating foods that don’t support nutritional or healing goals, having a discussion about these issues may be useful.

If you celebrated the Thanksgiving holiday by enjoying food with family or friends, you may be lamenting the sheer amount of food you ate, or the calories that you took in. Did you know that chewing your food well can not only affect how much you eat, but also how much nutrition you derive from food? In a meta-analysis by Miquel-Kergoat et al. on the affects of chewing on several variables, researchers found that chewing affects hunger, caloric intake, and even has an impact on gut hormones. Ten papers that covered thirteen trials were included in the meta-analysis. From these trials, the following data are reported:
Research about eating behavior theories are highlighted in this paper, and include a discussion of the variety of factors, both internal and external, that control eating. Chewing is described as providing “…motor feedback to the brain related to mechanical effort…” that may influence how full a person feels when eating foods that are chewed. On the contrary, foods and beverages that do not require much chewing may be associated with overconsumption due to the lack of chewing required. (This makes sense when considering sugar-laden, high-calorie beverages.) Additionally, chewing food mixes important digestive enzymes and breaks down the food properly in the mouth, making the process of digestion further along the digestive tract more efficient. Another study by Cassady et al. which assessed differences in hunger when chewing almonds 25 versus 40 times reported that increased chewing led to decreased hunger and increased satiety when compared to chewing only 25 times.
The theory presented, yet not concluded, in this paper is that chewing may affect gut hormones and thereby decrease self-reported hunger and decrease food intake. For various reasons, including deriving more nutrition from our food, avoiding overconsumption, or making the process of digestion more efficient, focusing more on the act of chewing our food can have beneficial affects.

Inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease (CD), according to Lan et al., are characterized by chronic inflammation in intestinal mucosa. There is little information available based on human studies that links nutritional support with inflammatory bowel disease. The authors of this article analyzed the available information about supplements that appear beneficial in healing the gut mucosa.
The intestinal epithelium acts as a selective barrier, and inflammatory bowel disease can disrupt this important barrier, affecting absorption, mucus production, and enteroendocrine secretion. Intestinal wound healing, according to the linked article, is “dependent on the precise balance of several processes including migration, proliferation, differentiation, and apoptosis of the epithelial cells.” Although there are few human clinical studies (more are animal and cell model studies) there is evidence that both macronutrient and micronutrient deficiencies may exist in patients who have inflammatory bowel disease. Patients may have malnutrition of proteins, of minerals and vitamins. Following are some points from the article:
The authors conclude that the exact mechanisms by which the various dietary compounds contribute to bowel healing is still unknown. Furthermore, the ability to make clear dietary recommendations is limited by the lack of clinical studies. At a minimum, this information can alert the pelvic rehab provider to discuss the potential benefits of nutrition on bowel health with patients. Many of us are quite comfortable giving advice about drinking appropriate amounts and types of fluid, or eating more whole and less processed foods. We can take our nutritional education a step further by encouraging a patient to discuss healing supplements with a provider and/or nutritionist to best support the healing bowel.
