BACKGROUND When a patient experiences an event other than the one of interest in the study, usually the probability of experiencing the event of interest is altered. By contrast, disease-free survival time analysis by standard methods, such as the Kaplan-Meier method and the standard Cox model, does not distinguish different causes in the presence of(More)
BACKGROUND Sleep health questionnaires are often employed as a first assessment step for sleep pathology. The Epworth Sleepiness Scale (ESS) and the Pittsburgh Sleep Quality Index (PSQI) are two commonly employed questionnaire instruments. Aspects of sleep health may be measured differently depending on choice of instrument. OBJECTIVES In a patient(More)
BACKGROUND The underlying mechanism of atopic dermatitis (AD) exacerbated by Staphylococcus aureus has not been established. However, we demonstrated recently that the majority of S. aureus strains colonized in the skin of Korean AD patients carried genes encoding staphylococcal enterotoxin A (SEA) and/or toxic shock syndrome toxin-1 (TSST-1). OBJECTIVE(More)
Melamine-induced renal toxicity is associated with crystal formation in the kidney following exposure to melamine and cyanuric acid. However, metabolomic profiling of intact kidney tissue after chronic intake of melamine and cyanuric acid (M + CA) mixtures has rarely been studied. The present study investigated the melamine-induced renal toxicity by(More)
Melamine-induced nephrotoxicity is closely associated with crystal formation in the kidney caused by combined exposure to melamine (Mel) and cyanuric acid (CA). However, there are few dosage-finding studies for toxicological evaluation of chronic co-exposure to Mel and CA. The objective of this study was to investigate the possible mechanism by which a Mel(More)
OBJECTIVE To assess the impact of clinical and social factors unique to HIV-infected adults in Saskatoon, Saskatchewan, regarding the rate of CD4(+) count change, and to identify factors associated with a risk of CD4(+) count decline. METHODS A retrospective longitudinal cohort study from medical chart reviews at two clinics was conducted in Saskatoon.(More)
BACKGROUND Alopecia areata (AA) is an organ-specific autoimmune disease that typically occurs in young adults. AA in the elderly is relatively rare, thus little data have been reported. OBJECTIVE This study aimed to understand the clinical characteristics of AA in the elderly. METHODS We performed a 10-year retrospective study of AA in the elderly who(More)
Epidermal nevi (EN) are hamartomatous lesions derived from epidermal components originating from pluripotent cell mutations. They have been categorized according to their predominant component. The existence of >2 types of EN concurrently within a single area or within contiguous areas has been rarely reported. This report describes the case of simultaneous(More)
BACKGROUND There are various histological prognostic parameters of cutaneous malignant melanoma, including tumor thickness and ulceration. Tumor-infiltrating lymphocytes (TIL) are among these parameters and can be further classified into three categories: 'absent', 'non-brisk' and 'brisk'. Brisk TIL usually indicates better clinical prognosis. Microscopic(More)
