Read Full License Page 1/8 Abstract BackgroundHenoch-Schonlein purpura (HSP) is a common autoimmune vasculitis in childhood. Although the detailed etiology of HSP remains unknown, several triggers, especially for infectious agents, have been proved to be associated with HSP onset. Case presentation: In the present report, we describe an unusual patient who suffered from HSP and incomplete lupus erythematosus (ILE) on day 8 after scabies, mainly based on nonthrombocytopenic purpura, abdominal pain, medium proteinuria, positive antinuclear antibody (ANA) and skin scrapings. A course of pulse methylprednisolone (10mg/kg/day) was administered for 6 days, followed by oral prednisone (1mg/kg/day). On day 18, the purpuric rashes almost disappeared, whereas medium proteinuria still existed. In this circumstance, a renal biopsy was performed with the informed consent of the parents. According to the criteria proposed by the International Study of Kidney Disease in Children, this patient was classied as class IIIb. The immunouorescence microscopy revealed granular deposits of IgA, IgM and C3 in the glomerular mesangium.

  • PATIENT INFORMATION LEAFLET Genital Warts
    PATIENT INFORMATION LEAFLET E A D V Genital warts (Condylomata acuminata) task force “skin disease in pregnancy” The aim of this leaflet This leaflet has been written to help you understand more about genital warts. It will tell you what it is, what causes it, what can be done about it, and where you can find out more information about it. What are genital warts? Genital or more accurately anogenital warts are skin lesions of the genital, perineal and anal areas; the medical term is condylomata acuminata. What causes genital warts? Genital warts are an infectious disease caused by sexually transmitted viruses, the Human Papilloma Virus (HPV), types 6 and 11. The incubation period (time between infectious contact and showing clinical signs) can be as long as eight months. Most infections by HPV cause no symptoms and clear within 2 years. This means that you might not realize that you carry the virus, (and there is a chance that you may infect another person without knowing it). The virus can persist for months or years in the skin, with or without symptoms. If the warts reappear after clearing it is usually due to the original not a new infection. Infection can occur in up to 30% of women between 20 and 30 years of age; elderly women are less frequently affected. Are genital warts hereditary? No. What are the signs and symptoms of genital warts? The presence of external genital warts (at the outside of the ano-genital skin) is nearly always detected by the woman herself. You do not usually feel them but there may be some degree of itching.

  • Epidemiology, Diagnosis, and Treatment of Scabies in a Dermatology Office
    J Am Board Fam Med: first published as 10.3122/jabfm.2017.01.160190 on 6 January 2017. Downloaded from ORIGINAL RESEARCH Epidemiology, Diagnosis, and Treatment of Scabies in a Dermatology Office Kathryn L. Anderson, MD, and Lindsay C. Strowd, MD Background: Scabies is a neglected skin disease, and little is known about current incidence and treat- ment patterns in the United States. The purpose of this study was to examine demographic data, treat- ment types, success of treatment, and misdiagnosis rate of scabies in an outpatient dermatology clinic. Methods: A retrospective chart review of patients diagnosed with scabies within the past 5 years was performed. Results: A total of 459 charts were identified, with 428 meeting inclusion criteria. Demographic data, diagnostic method, treatment choice, misdiagnosis rate, treatment failure, and itching after scabies are also reported. Children were the largest age group diagnosed with scabies, at 38%. Males (54%) were diagnosed with scabies more than females. The majority of diagnoses were made by visualizing ova, feces, or mites on light microscopy (58%). At the time of diagnosis, 45% of patients had been misdiag- nosed by another provider. Topical permethrin was the most common treatment used (69%), followed by a combination of topical permethrin and oral ivermectin (23%), oral ivermectin (7%), and other treatments (1%). Conclusion: Our findings suggest that more accurate and faster diagnostic methods are needed to limit unnecessary treatment and expedite appropriate therapy for scabies. (J Am

This summary is intended as a source of clinical guidance. When more than one therapeutic regimen is recommended, the sequence is in alphabetical order unless the choices for therapy are prioritized based on efficacy, cost, or convenience. The recommended regimens should be used primarily; alternative regimens can be considered in instances of substantial drug allergy or other contraindications.

  • Scabies and Impetigo
    Scabies and Impetigo Marlyn Mary Mathew Background • Scabies is an intensely pruritic, highly contagious infestation of the skin • Originally, scabies was a term used by the Romans to denote any pruritic skin disease. • In the 17th century, Giovanni Cosimo Bonomo identified the mite as one cause of scabies. Causes • The causative agent for this disease is Sarcoptes scabiei. • The mites that cause scabies burrow into the skin and deposit their eggs, forming a burrow that looks like a pencil mark. • Eggs mature in 21 days. The itchy rash is an allergic response to the mite. Symptoms • Itching, especially at night. • Rashes, especially between the fingers. • Sores (abrasions) on the skin from scratching and digging. • Thin, pencil-mark lines on the skin. • Mites may be more widespread on a baby's skin, causing pimples over the trunk, or small blisters over the palms and soles. • In young children, the head, neck, shoulders, palms, and soles are involved. • In older children and adults, the hands, wrists, genitals, and abdomen are involved. Epidemiology • Scabies infestation occurs worldwide and is very common. • It has been estimated that worldwide, about 300 million cases occur each year. Human scabies has been reported for over 2,500 years. • In the U.S., it is seen frequently in the homeless population but occurs episodically in other populations of all socioeconomic groups as well. Pathophysiology • Direct skin-to-skin contact is the mode of transmission. • Scabies mites are very sensitive to their environment. They can only live off of a host body for 24-36 hours under most conditions.
