We encountered two patients with congenital multiple plaquelike glomus tumors. These lesions were present at birth and enlarged with body growth, attaining a diameter of up to 13 cm. The diagnosis was confirmed by histologic and electron-microscopic examination, which revealed the typical changes of glomus tumors. Immunocytochemistry findings demonstrated the tumor cells to be vimentin- and alpha-smooth muscle-actin-positive and desmin-negative. On ultrastructural examination, typical dense bodies and attachment plaques were easily found within the tumor cells. Glomus cells were coated by a thick basal lamina.
Dimorphism of Pityrosporum orbiculare was induced in an artificial culture medium which consisted of 0.05 M glycine in 0.03-0.06 M ammonium phosphate buffer (pH 5.6), salts, glucose, and Tween-80. Of the strains tested, 78 to 85% produced hyphal elements from up to 8.5% of yeast cells. Morphologic features of P. orbiculare in culture were examined by scanning electron microscopy and compared with the appearance of fungus from clinical lesions of tinea versicolor. Morphologically, the fungi obtained in vivo and in vitro were identical.
Objectives: Describe State-of-the-Art in practice and research in caregiving with individuals, specifically, Veterans with traumatic brain injury (TBI) and the implications for current practice and future research. Sources: Professional literature and personal experience of review panel. Main Outcomes: Unpaid caregiving for individuals with TBI is most often provided by a spouse, parent or other blood relative; the majority of caregivers are women. Although caregiving can be rewarding, it also may create financial burden and psychological stress. Depression among family caregivers occurs four times more frequently than in the general population. Positive coping can help reduce the impact of stress, and Department of Veterans Affairs (VA) programmes are available to ease financial burden. Group interventions show promise in reinforcing and improving positive coping for both family caregivers and Veterans with TBI. Conclusions: Identifying the specific needs of caregivers and families of Veterans with TBI and other traumatic injuries, including post-traumatic stress syndrome (PTSD), will require further longitudinal research. Currently available group interventions and programmes appear to benefit injured Veterans and their family caregivers financially and psychologically. Increased understanding of characteristics of quality family caregiving and its long term costs and benefits is likely to lead to additional improvements in these interventions and programmes.ARTICLE HISTORY

In our series, chloromethoxy propyl mercuric acetate is a likely formaldehyde releaser (it also contains a mercuric ion) and 2-[(hydroxymethyl)amino ]ethanol is likely to yield both formaldehyde and ethanolamine in the presence of water and, in particular, under mildly acidic conditions.
