TRACE and Yohkoh Observations of High-Temperature Plasma in a Two-Ribbon Limb Flare.

The ability of the Transition Region and Coronal Explorer (TRACE) to image solar plasma over a wide range of temperatures (Te approximately 104-107 K) at high spatial resolution (0&farcs;5 pixels) makes it a unique instrument for observing solar flares. We present TRACE and Yohkoh observations of an M2.4 two-ribbon flare that began on 1999 July 25 at about 13:08 UT. We observe impulsive footpoint brightenings that are followed by the formation of high-temperature plasma (Te greater, similar10 MK) in the corona. After an interval of about 1300 s, cooler loops (Te<2 MK) form below the hot plasma. Thus, the evolution of the event supports the qualitative aspects of the standard reconnection model of solar flares. The TRACE and Yohkoh data show that the bulk of the flare emission is at or below 10 MK. The TRACE data are also consistent with the Yohkoh observations of hotter plasma (Te approximately 15-20 MK) existing at the top of the arcade. The cooling time inferred from these observations is consistent with a hybrid cooling time based on thermal conduction and radiative cooling.

Congenital cutaneous candidiasis associated with respiratory distress and elevation of liver function tests: a case report and review of the literature.

We describe congenital cutaneous candidiasis (CCC) in a term newborn. The mother had candidal vaginitis 1 week before delivery. At birth, the infant had a generalized, intensely erythematous, papulovesicular eruption, respiratory distress and elevation of liver function tests. The child responded well to intravenous amphotericin B plus topical and oral nystatin. There have been 13 previously reported cases of CCC in infants weighing more than 1500 gm who had evidence of systemic infection. Two deaths were attributed to candidal pneumonia and sepsis. The majority of infants with CCC have infection localized to the skin, but if there is any evidence of respiratory distress or signs of sepsis the possibility of systemic candidiasis and the need for parenteral antifungal therapy must be considered.

Public health nutrition practices to prevent low birth weight in eight southeastern states.

This study was conducted to identify current public health nutrition practices for the prevention and treatment of low-birth-weight (LBW) infants in eight southeastern states. Nutrition personnel (n = 1,054) were mailed a 51-item questionnaire with three parts that sought information on the respondents' professional backgrounds and employment status and on practice and standards of care for women before and during pregnancy and of LBW infants. Results based on a 62% response rate indicated 73% had worked in public health nutrition for 2 to 9 years, 56% were direct care providers, and 51% had bachelor's degrees. Only 40% of respondents indicated that their agencies had prepregnancy nutrition intervention protocols, whereas 89% indicated that they had high-risk pregnancy screening protocols and 91% indicated that they had high-risk treatment protocols. More than 91% indicated that their treatment protocols included guidelines for weight gain, preparation of nutrition care plans, and assessment of dietary and biochemical factors, health behavior, and obstetric history. Only 73% indicated inclusion of assessment of educational level. Nutritionists saw high-risk pregnant women (or those at risk for preterm labor) slightly more frequently during pregnancy than they saw low-risk women; however, the range (0.9 to 3.8 vs 0.5 to 2.3) and average (2.0 vs 1.2) number of visits for both groups differed only slightly. Nutritionists counseled women and charted in the medical record more frequently than they used nutrition care plans. To reduce LBW, nutritionists should implement treatment protocols and monitor high-risk women closely. The relationship between pre-pregnancy nutrition interventions and birth weight should be investigated.
