  • A. Syphilis Is a Systemic, Sexually Transmitted Disease (STD) Caused by the Treponema Pallidum Bacterium
    Oklahoma State Department of Health 03-2018 Revised SYPHILIS I. DEFINITION: A. Syphilis is a systemic, sexually transmitted disease (STD) caused by the Treponema pallidum bacterium. B. It can cause long-term complications if not treated correctly. Symptoms in adults are divided into stages. These stages are described below in the Clinical Features. Syphilis has been called ‘the great imitator’ because it has so many possible symptoms, many of which look like symptoms from other diseases. The painless syphilis chancre that clients get after they are first infected can be confused for an ingrown hair, zipper cut, or other seemingly harmless bump. Many times the client does not know they had a sore. The non-itchy body rash that develops during the second stage of syphilis can show up on the palms of the client’s hands and soles of their feet, all over the body, or in just a few places. The rash is usually bilateral, meaning it appears equally on both sides of the body. C. The three means of syphilis transmission are: 1. Person to person via vaginal, anal, or oral sex through direct contact with a syphilis chancre. 2. Person to person during foreplay, even when there is no penetrative sex (much less common). 3. Pregnant mother with syphilis to fetus - very serious complications may occur (fetal demise, long bone deformities, “saddle nose”). II. CLINICAL FEATURES: If left untreated, the disease progresses through several stages during which the infected person may or may not be symptomatic. The DIS and ‘Syphilis Diagnosis and Treatment Algorithm’ (Appendix 1) can assist with staging.

  • Fundamentals of Dermatology Describing Rashes and Lesions
    Dermatology for the Non-Dermatologist May 30 – June 3, 2018 - 1 - Fundamentals of Dermatology Describing Rashes and Lesions History remains ESSENTIAL to establish diagnosis – duration, treatments, prior history of skin conditions, drug use, systemic illness, etc., etc. Historical characteristics of lesions and rashes are also key elements of the description. Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin. Typically appears erythematous,

    VM-149 Koi Herpesvirus Disease (KHVD)1 Kathleen H. Hartman, Roy P.E. Yanong, Deborah B. Pouder, B. Denise Petty, Ruth Francis-Floyd, Allen C. Riggs, and Thomas B. Waltzek2 Introduction Koi herpesvirus (KHV) is a highly contagious virus that causes significant morbidity and mortality in common carp (Cyprinus carpio) varieties (Hedrick et al. 2000, Haenen et al. 2004). Common carp is raised as a foodfish in many countries and has also been selectively bred for the ornamental fish industry where it is known as koi. The first recognized case of KHV occurred in the United Kingdom in 1996 (Haenen et al. 2004). Since then other cases have been confirmed in almost all countries that culture koi and/ or common carp with the exception of Australia (Hedrick et al. 2000; Haenen et al. 2004, Pokorova et al. 2005). This information sheet is intended to inform veterinarians, biologists, fish producers and hobbyists about KHV disease. What Is KHV? Figure 1. Koi with mottled gills and sunken eyes due to koi Koi herpesvirus (also known as Cyprinid herpesvirus 3; herpesvirus disease. Credit: Deborah B. Pouder, University of Florida CyHV3) is classified as a double-stranded DNA virus herpesvirus, based on virus morphology and genetics, and belonging to the family Alloherpesviridae (which includes is closely related to carp pox virus (Cyprinid herpesvirus fish herpesviruses). The work of Waltzek and colleagues 1; CyHV1) and goldfish hematopoietic necrosis virus (Waltzek et al. 2005, 2009) revealed that KHV is indeed a (Cyprinid herpesvirus 2; CyHV2).

Natural History of Genital Warts: • A low risk HPV infection is usually not a serious or long term health concern and does not cause cancer. • Genital warts are almost always spread to others through direct, genital, skin to skin contact. • >91% of people with a history of a genital HPV infection that have a healthy immune system, will clear the virus or suppress the virus into a non detectable, dormant state. • If no visible wart is seen within 2 years it is considered a resolved infection unlikely to reappear or be spread to an uninfected partner.

  • Pediatric Viral Exanthema: a Review Article
    J Pediatr Rev. 2017 July; 5(2):e9487. doi: 10.5812/jpr.9487. Published online 2017 April 15. Review Article Pediatric Viral Exanthema: A Review Article Mohammed Jafar Saffar,1 Ghasem Rahmatpour Rokni,2,* and Mohammad Raeasian3 1Infectious Disease Research Center with Focus on Nosocomial Infection, Mazandaran University of Medical Sciences, Sari, IR Iran 2Department of Dermatology, Mazandaran University of Medical Sciences, Sari, IR Iran 3General Practitioner, Mazandaran University of Medical Sciences, Sari, IR Iran *Corresponding author: Dr Ghasem Rahmatpour Rokni, MD, Pasdaran Boulevard, Bo Ali Sina Hospital, Sari, Mazandaran Province, IR Iran. Tel: +98-9125443956, E-mail: [email protected] Received 2016 October 25; Revised 2017 March 07; Accepted 2017 March 13. Abstract Context: Many diseases caused by viral agents are associated with fever and cutaneous manifestations. Viral exanthema is a widespread nonspecific skin rash, commonly characterized by generalized eruption of erythematous macules and papular lesions. Although these rashes are mostly benign and self-limited, some may be serious and life-threatening. Differentiation between severe and benign types is clinically important and life-saving. Evidence Acquisition: In this narrative review, electronic databases, including Google Scholar, Science Direct, PubMed (including Medline), Web of Science, Scientific Information Database, and Scopus, were searched. We conducted a narrative review of papers published on pediatric viral exanthema during 2000 - 2016. The used keywords included “viral exanthema”, “fever”, and “skin rash”. Articles on skin rash, caused by drug reactions or nonviral exanthema, were excluded. Results: Different viral agents can cause different types of skin reactions. Cutaneous manifestations and skin rashes can be cate- gorized, based on the form of the rash (macular, papular, vesicular, blistery, petechial, and purpuric) or the general term, which denotes illnesses such as measles-like morbilliform rash, rubella or rubelliform rash, and scarlatiniform rash, a scarlet-fever like infection.

  • HPV Induced Proliferative Verrucous Leukoplakia : Case Report
    International J. of Healthcare and Biomedical Research, Volume: 2, Issue: 4, July 2014, Pages 58-62 Case Report: HPV induced Proliferative verrucous Leukoplakia : Case Report Dr Gopal Sharma, Dr Deepa Das , Dr Prachi Naik , Dr Jaya Mukherjee Oral Medicine and Radiology Department, YMT Dental College and Hospital, Mumbai. India Corresponding author: Dr Jaya Mukherjee Abstract: Proliferative verrucous leukoplakia (PVL) is a recently delineated entity that is defined as a diffuse, white and smooth or papillary or wart like area of the oral mucosa caused by varying degrees of epithelial hyperplasia. 1 The synonymous term is oral florid papillomatosis. Ismail mullah a 32yr old man reported to Ymt Dental College and Hospital with a chief complaint of a white growth protruding out of the mouth since 1 yr. Patient also reported of esthetic concern and reduced mouth opening due to the growth. The patient first noticed a small white growth 1 year back in the lower left region of the mouth. The patient ignored the growth since it was small and painless. PVL has different features in these populations. Treatment recommendation includes multiple techniques such as CO2 laser surgery, surgery with radiotherapy, cryotherapy, retinoid, systemic vitamin A, bleomycin and photodynamic therapy. 12 Whether PVL progresses especially rapidly in Asian or Indian populations requires further investigation. Thehealth of these patients, especially their immune status,warrants examination for its contribution to the aetiology of PVL.

  • Diagnostic Discussion
    Diagnostic Discussion Diagnostic Discussion By Drs. Indraneel Bhattacharyya and Nadim Islam A 44-year-old female was referred to Dr. Daniel Lauer, a periodontist in Palm Beach Gardens, Fla., for evaluation of a mildly symptomatic lesion on the palate (Fig. 1) by her dentist, Dr. Jimmy Chen, also of Palm Beach Gardens. The patient reported a his- tory of food-related trauma to her palate four to six weeks before the lesion appeared. She complained of mild irritation in the area, especially on food con- sumption. Her medical history was non-contributory and she reports no prior history of similar lesions. Fig. 1 She is a non-smoker. The lesion appeared slightly “bumpy” on the surface and was slightly reddish- to flesh-colored. It measured approximately 1 x 0.4 cm and was roughly rectangular in shape. Slight ery- thema was noted around the lesion. The lesion was entirely excised and submitted to the University of Florida College of Dentistry Oral Pathology Biopsy Service. The biopsy showed a papillary proliferation of epithelium with significantly thickened keratin with elongated rete ridges and foamy cells in the connec- tive tissue (Fig. 2). Question: Which of the following is the most likely diagnosis? A. Verrucous Leukoplakia B. Verruca Vulgaris C. Condyloma Acuminatum (venereal wart) D. Focal Epithelial Hyperplasia (Heck’s Disease) E.

  • Wart Treatment
    Wart Treatment Skin Warts Common skin warts (also called cutaneous warts) are raised round or oval growths. A wart may be lighter or darker than the skin around it. Some warts may have tiny black dots in them, often called seeds. The dots are small, clotted blood vessels. Warts may occur alone or in larger groups that merge and form patches. You can become infected with the virus that causes warts buy touching another person’s wart. The virus is more likely to infect skin that is injured or softened by water, but it can infect healthy skin as well. It can take up to six months after exposure to the virus for a wart to appear. Who gets skin warts? Skin warts are most common in children and young adults. People who have chronic skin conditions, such as eczema, many have more extensive warts or warts that are difficult to control. Where do warts occur? Skin Warts can occur in the following locations: Common skin warts, also call verruca vulgaris, can occur on any area skin, but are often seen on the fingers, hands knees, and elbows. When common warts are located around the fingernails, they are call periungual warts. Plantar warts are found on the soles of the feet. Flat warts are most commonly found on the back of the hands face, and lower legs. Skin Wart Diagnosis: Skin warts can usually be diagnosed based upon how they look. Skin biopsy or other testing is not usually necessary. Skin Wart Treatment: Treatment of warts depends upon where the wart is located and how much it bothers you.
