  • Arsenicosis Presenting with Cutaneous Squamous Cell Carcinoma: a Case Report
    CASE REPORT Arsenicosis Presenting with Cutaneous Squamous Cell Carcinoma: A Case Report Marie Len A. Camaclang,1 Eileen Liesl A. Cubillan2 and Claudine Yap-Silva2 1Section of Dermatology, Department of Medicine, Philippine General Hospital, University of the Philippines Manila 2Section of Dermatology, Department of Medicine, College of Medicine and Philippine General Hospital, University of the Philippines Manila ABSTRACT A 29-year-old male with eleven-year history of hyperkeratotic papules and speckled pigmentation developed cutaneous squamous cell carcinoma. Arsenicosis was confirmed by elevated hair arsenic level, and histopathologic findings of arsenical keratosis and one lesion showing carcinoma-in-situ. Chronic arsenic exposure has been found to activate inflammatory and carcinogenic pathways leading to development of pre-malignant and malignant lesions. A multi-disciplinary approach involving healthcare specialists and environmentalists is crucial in source control and management of long-term complications. Key Words: arsenic, arsenic poisoning, arsenicosis, skin cancer, squamous cell carcinoma INTRODUCTION Arsenic is a potential human carcinogen of public health concern. Exposure may be via inhalation of arsenic dusts, direct contact with arsenites, or ingestion of contaminated water, the latter being the most common route.1 Chemical contamination of groundwater may come from natural sources such as geochemical processes (e.g. volcanic activities), as well as the result of human activities including mining wastes, landfills,

ABSTRACT Eosinophilic Cellulitis is also known as Wells syndrome is uncommon dermatitis, characterized by the infiltration of eosinophils in the dermis. The exact etiology of the disease is unknown. Clinically, it is highly varied but commonly the presentation is pruritic erythematous plaque. We report a case of one and half years old healthy boy who developed itchy bullae on the dorsum of his hand with multiple erythematous papules over his extremities that started immediately after his vaccines. Histopathological examination of the lesion showed infiltrate eosinophils with typical flame figures. The case was successfully treated with corticosteroid course.

  • Pustular Psoriasis in Children- a Review
    Vol. 10, No. 1, 2012 Review Article Pustular Psoriasis in Children- a Review Malathi M 1, Thappa DM 2 1Senior Resident, 2Professor and Head, Department of Dermatology and STD, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry-605006, India Abstract Pustular psoriasis is a rare form of psoriasis in the pediatric population with the acute generalized and annular variants being the most common. There are two groups of pustular psoriasis one with a history of psoriasis vulgaris and the other without a history of psoriasis vulgaris which differ in various aspects including the age at onset and triggering factors. Several triggering factors have been implicated in generalized pustular psoriasis, the removal or treatment of which can allow the process to settle, which include upper respiratory tract and urinary tract infections, abrupt cessation of oral steroids and cyclosporine, sunburn, tar therapy, hypocalcemia and vaccination. But, generalized pustular psoriasis may present with potential life threatening complications warranting aggressive approach with various treatment modalities like retinoids, methotrexate, cyclosporine, dapsone and biologics which are frequently being used in children. However, the management issues in the pediatric age group are challenging pertaining to a host of precipitating factors, limited clinical experience with the optimal use of these agents in children, long term safety profile of these agents in the long run in children and the lack of long term follow up studies.

However, recent human activities have resulted in even greater arsenic exposures and the potential increase for chronic arsenic poisoning on a worldwide basis. This is especially the case in China, Taiwan, Thailand, Mexico, Chile, and India. The sources of arsenic expo- José A. Centeno, Ph.D. sure vary from burning of arsenic-rich coal (China) and mining activities (Malaysia, Japan) to the ingestion of arsenic-contami- nated drinking water (Taiwan, Philippines, Mexico, Chile). The groundwater arsenic contamination in Bangladesh and the West Bengal Delta of India has received the greatest international attention due to the large number of people potentially exposed and the high prevalence of arsenic-induced diseases.

  • The Management of Psoriasis in Adults
    DORSET MEDICINES ADVISORY GROUP THE MANAGEMENT OF PSORIASIS IN ADULTS Psoriasis is a common, genetically determined, inflammatory and proliferative disorder of the skin, the most characteristic lesions consisting of chronic, sharply demarcated, dull-red, scaly plaques, particularly on the extensor prominences and in the scalp. Self-care advice Many people's psoriasis symptoms start or become worse because of a certain event, known as a trigger. Common triggers include: • an injury to skin such as a cut, scrape, insect bite or sunburn (this is known as the Koebner response) • drinking excessive amounts of alcohol • smoking • stress • hormonal changes, particularly in women (for example during puberty and the menopause) • certain medicines such as lithium, some antimalarial medicines, anti-inflammatory medicines including ibuprofen, ACE inhibitors (used to treat high blood pressure) and beta blockers (used to treat congestive heart failure) • throat infections - in some people, usually children and young adults, a form of psoriasis called guttate psoriasis (which causes smaller pink patches, often without a lot of scaling) develops after a streptococcal throat infection, although most people who have streptococcal throat infections do not develop psoriasis • other immune disorders, such as HIV, which cause psoriasis to flare up or to appear for the first time Advice for patients can be found here Management pathway For people with any type of psoriasis assess: • disease severity • the impact of disease on physical, psychological and social wellbeing • whether they have psoriatic arthritis • the presence of comorbidities. • Consider using the Dermatology quality of life assessment: www.pcds.org.uk/p/quality-of-life Assess the severity and impact of any type of psoriasis: • at first presentation • before referral for specialist advice and at each referral point in the treatment pathway • to evaluate the efficacy of interventions.

ABSTRACT The high recurrence rates of colorectal cancer have been associated with a small population of cancer stem cells (CSCs) that are resistant to the standard chemotherapeutic drug, 5-fluorouracil (5FU). Thymoquinone (TQ) has shown promising antitumor properties on numerous cancer systems both in vitro and in vivo; however, its effect on colorectal CSCs is poorly established. Here, we investigated TQ’s potential to target CSCs in a three-dimensional (3D) sphere-formation assay enriched for a population of colorectal cancer stem/progenitor cells.
