Long-term Reproducibility of Respiratory Gas Exchange Measurements during Exercise in Patients: METHODS
28, Feb 2011Ritient Population Sixteen successive outpatients with chronic, stable, cardiac failure were selected on the basis of their having had, in addition to their first test that was not included in the analysis, at least four exercise tests during a period of time that exceeded three months. In addition, there had to be at least five [...]

Long-term Reproducibility of Respiratory Gas Exchange Measurements during Exercise in Patients
27, Feb 2011Present-day technology has greatly facilitated the monitoring of respiratory gas exchange in the clinical exercise laboratory and has provided an important adjunct to the evaluation of patients with stable heart failure. On-line, breath-by-breath measurements of oxygen uptake (Vo2), carbon dioxide production (VcOa), and minute ventilation (Ve) are now possible. The monitoring of these variables together [...]

A Case of Dermatitis Neglecta: DISCUSSION
26, Feb 2011Poskitt et al first described dermatitis neglecta (unwashed dermatosis) in 1995. They reported 3 cases of pigmented hyperkeratotic plaques on various sites, and these plaques were the result of avoiding washing the affected areas. Ruiz-Maldonado et al added two more cases of dermatitis neglecta in 1999, and the lesions resembled verrucous nevi around the areolas [...]

A Case of Dermatitis Neglecta: CASE REPORT
25, Feb 2011A 29-year-old man presented with an asymptomatic thick scaly plaque on the umbilicus (Fig. 1A). The lesion was incidentally found by the patient himself the day before he visited the clinic. He reported no history of any preceding eruption, injury to the skin or any family history of skin diseases. On the physical [...]

A Case of Dermatitis Neglecta
24, Feb 2011INTRODUCTION Dermatitis neglecta (unwashed dermatosis) was first described by Poskitt et al in 1995. They reported 3 cases of pigmented hyperkeratotic plaques on various sites, and these plaques were the result of avoiding washing the affected areas. All of the lesions were rapidly resolved with normal washing by gently wiping with an alcohol swab.

LPP, a disease of unknown etiology, manifests as hyperpigmented, dark brown, occasionally pruritic macules and/or papules. The course of the disease is characterized by exacerbations and remissions. It is known to be more chronic than classical LP is. With regard to the coexistence of classic LP in a number of LPP patients and the histopathological [...]
The first patient was a 49-year-old woman who presented complaining of violaceous reticulated patches and scattered rice grain-sized macules localized to the left inguinal area for several months (Fig. 1A). She had no subjective symptoms, such as pruritus or pain. She had not come into contact with any chemicals, animals, or plants, nor had she [...]
