Burning Mouth Syndrome The main symptom of burning mouth syndrome is a burning sensation involving the tongue, lips, gums, palate, throat or widespread areas of the whole mouth. People with the syndrome may describe the sensation in the affected areas as hot or scalded, as if they had been burned with a hot liquid. Burning Mouth Syndrome Dry mouth Sore mouth A tingling or numb sensation in your mouth or on the tip of your tongue A bitter or metallic taste Causes Dry mouth (xerostomia). Nutritional deficiencies Allergies. Psychological factors. Nerve disturbance or damage (neuropathy). Treatments Potentially efficacious medicines include: * tricyclic antidepressants (like amitriptyline - brand name, Elavil) * benzodiazepines (like clonazepam - brand name, Klonopin; or *chlordiazepoxide brand name - Librium) * even anticonvulsants have proven effective in some cases. BMS: Treatment Tricyclic antidepressants Amitriptyline (Elavil)10 to 150 mg per day 10 mg at bedtime; increase dosage by 10 mg every 4 to 7 days until oral burning is relieved or side effects occur BMS: Treatment Benzodiazepines Clonazepam (Klonopin)0.25 to 2 mg per day0.25 mg at bedtime; increase dosage by 0.25 mg every 4 to 7 days until oral burning is relieved or side effects occur; as dosage increases, medication is taken as full dose or in three divided doses BMS: Treatment Anticonvulsants Gabapentin (Neurontin) 300 to 1,600 mg per day100 mg at bedtime; increase dosage by 100 mg every 4 to 7 days until oral burning is relieved or side effects occur; as dosage increases, medication is taken in three divided doses C Candidiasis Oral thrush and other Candida infections occur when your immune system is weakened by disease or drugs such as prednisone, or when antibiotics disturb the natural balance of microorganisms in the body. Predisposing factors for infection Infancy or old age Serious underlying disease, such as cancer or infection with HIV Dry mouth due to disease of the salivary glands or medications e.g. antihistamines, diuretics Dentures (especially if they are not regularly cleaned or fit badly) Predisposing factors for infection Smoking Injury to the mouth Nutritional deficiency e.g. iron &/or B-vitamin deficiency Inhaled corticosteroids used to treat asthma e.g. beclometasone, budesonide, fluticasone. Drink water after inhalation to reduce this complication Clinical features Acute pseudomembranous candidiasis. There are white patches on gums, tongue & inside the mouth that can be peeled off leaving a raw area. Acute atrophic candidiasis. There are smooth red shiny patches on the tongue. The mouth is very sore. Chronic atrophic candidiasis. This is common in those with dentures. The underlying mucosa is red and swollen. Clinical features Angular

Prakash vijayan Email: [email protected] Abstract: Keratocystic odontogenic tumor (KCOT) formerly known as odontogenic keratocyst (OKC), is considered a benign unicystic or multicystic intraosseous neoplasm and one of the most aggressive odontogenic lesions presenting relatively high recurrence rate and a tendency to invade adjacent tissue. On the other hand Dentigerous cyst (DC) is one of the most common odontogenic cysts of the jaws and rarely recurs. They were very similar in clinical and radiographic characteristics. In our case a pathological report following incisional biopsy turned out to be dentigerous cyst and later as Keratocystic odontogenic tumour following total excision. The treatment was chosen in order to prevent any pathological fracture. A recurrence was noticed after 2 months following which the lesion was surgically enucleated. At 2-years of follow-up, patient showed no recurrence. Keywords: Dentigerous cyst, Keratocystic odontogenic tumour (KCOT), Recurrence, Enucleation INTRODUCTION Keratocystic odontogenic tumour (KCOT) is a CASE REPORT rare developmental, epithelial and benign cyst of the A 17-year-old patient reported to the OP with a jaws of odontogenic origin with high recurrence rates.

  • 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.

  • Senescence and Apoptosis in Carcinogenesis of Cervical Squamous Carcinoma
    Modern Pathology (2007) 20, 961–966 & 2007 USCAP, Inc All rights reserved 0893-3952/07 $30.00 www.modernpathology.org Senescence and apoptosis in carcinogenesis of cervical squamous carcinoma Wei Feng1, Jianguo Xiao1, Zhihong Zhang2, Daniel G Rosen2, Robert E Brown1, Jinsong Liu2 and Xiuzhen Duan1 1Department of Pathology, The University of Texas Medical School at Houston, Houston, TX, USA and 2Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA Senescence and apoptosis are two key mechanisms that protect against cancer development. Many cell cycle regulators, such as p14ARF, p15INK4b and p16INK4a, are important in G1 cell cycle arrest and oncogene-induced senescence. The bcl-2 protein is one of the key components that control apoptosis, while the p53 protein plays key roles in both mechanisms. The genes of these key regulator proteins are often mutated or deleted in various malignancies. It is unknown how senescence and apoptosis are regulated in one of the most common tumors of the female genital tract, cervical squamous cell carcinoma (SCC). In this study the, expression of senescence, apoptosis and proliferation markers in normal cervical epithelium, cervical intraepithelial neoplasia (CIN) and SCC are characterized via immunohistochemical staining for p14ARF, p15INK4b, p16INK4a, bcl-2, p53 and Ki-67 in tissue microarray blocks containing 20 samples each of normal cervix, moderate-to-severe cervical dysplasia (CIN II–III) and invasive SCC. Samples are derived from 60 total cases of cervical biopsies and cervical conizations. Results showed that the proliferation marker, Ki-67, is markedly increased, and the senescence markers, p15INK4b, p16INK4a and p14ARF are overexpressed in both dysplasia and carcinoma.

  • Clinical Practice Statements-Oral Contact Allergy
    Clinical Practice Statements-Oral Contact Allergy Subject: Oral Contact Allergy The American Academy of Oral Medicine (AAOM) affirms that oral contact allergy (OCA) is an oral mucosal response that may be associated with materials and substances found in oral hygiene products, common food items, and topically applied agents. The AAOM also affirms that patients with suspected OCA should be referred to the appropriate dental and/or medical health care provider(s) for comprehensive evaluation and management of the condition. Replacement and/or substitution of dental materials should be considered only if (1) a reasonable temporal association has been established between the suspected triggering material and development of clinical signs and/or symptoms, (2) clinical examination supports an association between the suspected triggering material and objective clinical findings, and (3) diagnostic testing (e.g., dermatologic patch testing, skin-prick testing) confirms a hypersensitivity reaction to the suspected offending material. Originators: Dr. Eric T. Stoopler, DMD, FDS RCSEd, FDS RCSEng, Dr. Scott S. De Rossi, DMD. This Clinical Practice Statement was developed as an educational tool based on expert consensus of the American Academy of Oral Medicine (AAOM) leadership. Readers are encouraged to consider the recommendations in the context of their specific clinical situation, and consult, when appropriate, other sources of clinical, scientific, or regulatory information prior to making a treatment decision. Originator: Dr. Eric T. Stoopler, DMD, FDS RCSEd, FDS RCSEng, Dr. Scott S.

  • 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.
