  • Management of Saliva and Drooling Excessive Saliva and Drooling Affects up to 50% of People with Parkinson’S (PD)
    Management of Saliva and Drooling Excessive saliva and drooling affects up to 50% of people with Parkinson’s (PD). Drooling can be embarrassing and can limit social interactions for the person with PD. Saliva and Drooling Parkinson Information Parkinson It can also be an important symptom of swallowing difficulty, which can increase the risk of choking on saliva. People with Parkinson’s disease do not swallow automatically due to rigidity and impaired mobility of the muscles of the palate, throat and esophagus. Saliva pools in the mouth and can potentially become a hazard since swallowing into the lungs carries the risk of pneumonia. If you have poor posture, saliva collects in the front of the mouth, resulting in drooling. Cause and symptoms Decreased control of saliva is most often caused by changes in the ability to swallow, rather than from producing too much saliva. A common cause of drooling for people with PD is the weakening and/or loss of motor control of the muscles involved in swallowing. You may experience one or more of the following symptoms: • Decreased ability to keep your mouth closed at rest, known as the “open mouth posture” • Difficulty keeping lips closed • Lack of awareness of the saliva in your mouth • Wetness at the sides of your mouth • A wet sounding voice • Drooling with posture changes • Coughing and/or choking Evaluation and treatment Speak with your physician about all symptoms that may not be related to PD. If you are experiencing drooling or choking on your saliva, you may require a swallowing evaluation by a Speech Language Pathologist.

  • Recognizing Benign and Malignant Skin Conditions by Claudia Joy Wingo
    Protecting Our Shell: Recognizing Benign and Malignant Skin Conditions By Claudia Joy Wingo Learning Outcomes: Participants who attend this presentation should have: • Learned basic terminology, pathophysiology and methods of diagnosis for a variety of skin lesions. • Gained a basic understanding on the difference of appearance between benign and malignant skin lesions. • Acquired specific herbal protocols in reference to skin conditions and lesions. Skin cancer is the most common form of cancer in the United States with more than 2 million cases diagnosed each year. The large majority of these are slow growing, non-melanoma skin cancers (NMSC) but early detection is important to prevent lesion infiltration, disfigurement and possible loss of function as well as recognition of the rarer but more dangerous melanoma lesions (Mahon SM, 2011). As herbalists, naturopaths and integrative health practitioners we pride ourselves on client-centered care, taking the time to do a thorough and extensive client intake. In this role, it is important that we have the basic skills to recognize and distinguish a variety of skin conditions including cutaneous skin lesions. This pictorial presentation seeks to educate herbal and integrative health practitioners on the appearance of both benign and malignant skin lesions and possible herbal recommendations for the prior. We will briefly cover skin physiology and pathophysiology, methods of clinical diagnosis, associated risk factors and identifying features of a variety of common skin lesions. This in turn, will aid the practitioner in knowing when to refer the client on. Herbal protocols for support and prevention of recurrence as well as case studies will be covered.

    Tuesday – June 18, 2013 8:30 am – 11:30 am Poster Abstracts – Tuesday, June 18, 2013 #1 ORAL LESIONS AS THE PRESENTING MANIFESTATION OF CROHN'S DISEASE V Woo, E Herschaft, J Wang U of Nevada, Las Vegas Crohn’s disease (CD) is an immune-mediated disorder of the gastrointestinal tract which together with ulcerative colitis, comprise the two major types of inflammatory bowel disease (IBD). The underlying etiology has been attributed to defects in mucosal immunity and the intestinal epithelial barrier in a genetically susceptible host, resulting in an inappropriate inflammatory response to intestinal microbes. The lesions of CD can affect any region of the alimentary tract as well as extraintestinal sites such as the skin, joints and eyes. The most common presenting symptoms are periumbilical pain and diarrhea associated with fevers, malaise and anemia. Oral involvement has been termed oral CD and may manifest as lip swelling, cobblestoned mucosa, mucogingivitis and linear ulcerations and fissures. Oral lesions may precede gastrointestinal involvement and can serve as early markers of CD. We describe a 6-year-old male who presented for evaluation of multifocal gingival erythema and swellings. His medical history was unremarkable for gastrointestinal disorders or distress. Histopathologic examination showed multiple well-formed granulomas that were negative for special stains and foreign body material. A diagnosis of granulomatous gingivitis was rendered. The patient was advised to seek consultation with a pediatric gastroenterologist and following colonoscopy, was diagnosed with early stage CD. Timely recognition of the oral manifestations of CD is critical because only a minority of patients will continue to exhibit CD-specific oral lesions at follow-up.

A recent study from this laboratory used microsatellite analysis to evaluate OLP for loss of heterozygosity (LOH) at loci on three chromosomal arms (3p, 9p, and 17p) (Am J Path 1997;Vol151:Page323-Page327). Loss on these arms is a common event in oral epithelial dysplasia and has been associated with risk of progression of oral leukoplakia to cancer. The data showed that, although dysplastic epithelium demonstrated a high frequency of LOH (40% for mild dysplasia), a significantly lower frequency of LOH was noted in OLP (6%), which is even lower than that in hyperplasia (14%).

  • Pediatric Oral Pathology. Soft Tissue and Periodontal Conditions
    PEDIATRIC ORAL HEALTH 0031-3955100 $15.00 + .OO PEDIATRIC ORAL PATHOLOGY Soft Tissue and Periodontal Conditions Jayne E. Delaney, DDS, MSD, and Martha Ann Keels, DDS, PhD Parents often are concerned with “lumps and bumps” that appear in the mouths of children. Pediatricians should be able to distinguish the normal clinical appearance of the intraoral tissues in children from gingivitis, periodontal abnormalities, and oral lesions. Recognizing early primary tooth mobility or early primary tooth loss is critical because these dental findings may be indicative of a severe underlying medical illness. Diagnostic criteria and .treatment recommendations are reviewed for many commonly encountered oral conditions. INTRAORAL SOFT-TISSUE ABNORMALITIES Congenital Lesions Ankyloglossia Ankyloglossia, or “tongue-tied,” is a common congenital condition characterized by an abnormally short lingual frenum and the inability to extend the tongue. The frenum may lengthen with growth to produce normal function. If the extent of the ankyloglossia is severe, speech may be affected, mandating speech therapy or surgical correction. If a child is able to extend his or her tongue sufficiently far to moisten the lower lip, then a frenectomy usually is not indicated (Fig. 1).

  • Spectrum of PEX1 and PEX6 Variants in Heimler Syndrome
    European Journal of Human Genetics (2016) 24, 1565–1571 Official Journal of The European Society of Human Genetics www.nature.com/ejhg ARTICLE Spectrum of PEX1 and PEX6 variants in Heimler syndrome Claire EL Smith1, James A Poulter1, Alex V Levin2,3,4, Jenina E Capasso4, Susan Price5, Tamar Ben-Yosef6, Reuven Sharony7, William G Newman8,9, Roger C Shore10, Steven J Brookes10, Alan J Mighell1,11,12 and Chris F Inglehearn*,1,12 Heimler syndrome (HS) consists of recessively inherited sensorineural hearing loss, amelogenesis imperfecta (AI) and nail abnormalities, with or without visual defects. Recently HS was shown to result from hypomorphic mutations in PEX1 or PEX6,both previously implicated in Zellweger Syndrome Spectrum Disorders (ZSSD). ZSSD are a group of conditions consisting of craniofacial and neurological abnormalities, sensory defects and multi-organ dysfunction. The finding of HS-causing mutations in PEX1 and PEX6 shows that HS represents the mild end of the ZSSD spectrum, though these conditions were previously thought to be distinct nosological entities. Here, we present six further HS families, five with PEX6 variants and one with PEX1 variants, and show the patterns of Pex1, Pex14 and Pex6 immunoreactivity in the mouse retina. While Ratbi et al. found more HS-causing mutations in PEX1 than in PEX6, as is the case for ZSSD, in this cohort PEX6 variants predominate, suggesting both genes play a significant role in HS. The PEX6 variant c.1802G4A, p.(R601Q), reported previously in compound heterozygous state in one HS and three ZSSD cases, was found in compound heterozygous state in three HS families.
