A case of Bowen disease (BD) presenting as longitudinal melanonychia (LM) on the right third fingernail of a 25-year-old African American man is described. Findings from the histopathologic examination revealed full-thickness epidermal atypia, hypergranulosis, and koilocytic changes. Human papillomavirus (HPV) type 56 was identified by polymerase chain reaction. To the best of our knowledge, we...
Familial arteriovenous malformations (AVM) in the brain is a very rare disease. It is defined as its occurrence in two or more relatives (up to third-degree relatives) in a family without any associated disorders, such as hereditary hemorrhagic telangiectasia. We encountered a Japanese family with brain AVM in which four affected members in four successive generations were observed. One DNA sam...
onychomycosis: a rare presentation of fungal urinary tract infection in an extremely preterm neonate
onychomycosis refers to nail infections, caused by fungi including yeasts and non-dermatophyte moulds. one or several toenails or fingernails (seldom all) may be involved in this condition. many cases of fingernail onychomycosis are due to yeasts. fungal infection has emerged as an important cause of neonatal infection, associated with significant morbidity and mortality, especially in very low...
Injuries to oral soft-tissues can occur due to accidental, iatrogenic, and factitious traumas. Traumatic lesions, whether chemical, physical, or thermal in nature, are among the most common in the mouth. A type of physical injury to the gingival tissues is self-inflicted. Sometimes the lesions are termed gingivitis artefacta. Self-inflicted gingival injuries in children and adolescents can occu...
Results of a feasibility study for the use of the Q-band EPR measurements of fingernails are presented. Details of the first protocol developed for Q-band (34 GHz) EPR dose measurements in fingernails and preliminary results of a dosimetry study in comparison with the commonly-used X-band (9 GHz) are reported. It was found that 1e5 mg sample mass was sufficient for EPR measurements in fingernai...
Electron paramagnetic resonance (EPR) is a promising biodosimetric method, and fingernails are sensitive biomaterials to ionizing radiation. Therefore, kinetic energy released per unit mass (kerma) can be estimated by measuring the level of free radicals within fingernails, using EPR. However, to date this dosimetry has been deficient and insufficiently accurate. In the sampling processes and m...
UNLABELLED Widespread hyperalgesia is well documented among adult patients with irritable bowel syndrome (IBS), but little is known about pain sensitivity among adolescents with IBS. We examined pain sensitivity in 961 adolescents from the general population (mean age 16.1 years), including pain threshold and tolerance measurements of heat (forearm) and pressure pain (fingernail and shoulder) a...
With its population of over 1.3 billion persons, China offers abundant opportunities to discover causes of disease. However, few rigorous population-based case-control studies have as yet been conducted in mainland China. We conducted a population-based case-control study of nasopharyngeal carcinoma in Guangdong Province and Guangxi Autonomous Region. We collected questionnaires and biospecimen...
Results A total of 88 subjects were examined (45men and 43 women); the average age were 41 years old. Abnormal appearing nails were present in 48 cases. Mycologic evidence of onychomycosis were present in 42 cases. The clinical presentation of onychomycosis was: distal and lateral subungual onychomycosis (47%); white superficial onychomycosis (5%); proximal subungual onychomycosis (21%); total ...
