Skin problems after a tsunami

BACKGROUND: On December 26, 2004, the biggest earthquake for 40 years, measuring 9.0 on the Richter scale, triggered a tsunami that pounded the coastal areas of South Asia and East Africa. The effects of the tsunami on skin conditions have not been evaluated. OBJECTIVE: To determine the influence of the tsunami on skin conditions by evaluating the skin problems of patients presenting at hospitals after the tsunami. METHODS: Between 5 and 25 January 2005, two dermatologists evaluated patients who complained of skin problems at an outpatient clinic and emergency room of a general hospital in Banda Aceh, Aceh Province, Indonesia. RESULTS: The total number of patients that presented during the study period was 235 (131 males and 104 females), and they had a total of 265 skin problems. In terms of age distribution, most subjects were in their fourth decade (23.0%), followed by the third (22.6%) and fifth decade (16.6%). The most prevalent skin problems were infections-infestations (32.5%), followed by eczemas (29.8%) and traumatic skin disorders (29.4%). In males, traumatic skin disorders were most common. The great majority of infection-infestation cases involved superficial fungal infections. Contact dermatitis accounted for three-quarters of eczema cases, and mainly involved the arms (40.0%) and legs (27.1%). The majority of traumatic skin disorders were lacerations, punctures and penetrations, and the feet (44.7%) and hands (18.8%) were most frequently affected. CONCLUSIONS: Unhygienic conditions, exposure to a hazardous environment and contact with various objects during and after the tsunami probably increased the prevalence of infections-infestations, traumatic skin disorders and contact dermatitis. To prevent these problems and associated secondary bacterial infections, health-related education and early medical management are required.     

The influence of stimulus size on measured visual field extent in infants.

PURPOSE: To compare measured visual field extent for a 6 degrees stimulus (typical size used in studies of infants) with a 1.5 degrees stimulus (similar to the largest size used in Goldmann perimetry) in young infants. METHODS: A total of 120 infants (60 each at 3.5 months and 7 months of age) and 24 adults were tested monocularly with a kinetic perimetry procedure using a black double-arc perimeter. Each subject was tested with either a 6 degrees or 1.5 degrees white sphere, which was mounted on a black wand and moved smoothly toward the intersection of the perimeter arms at 3.4 degrees /s. Visual field extent along each perimeter arm was defined as the median of 2 to 3 measurements of the position of the leading edge of the stimulus when the subject made an eye movement toward the stimulus. RESULTS: The 6 degrees stimulus produced larger measured visual field extent than the 1.5 degrees stimulus in 3.5-month olds (temporal field only) and in 7-month olds (nasal and temporal field), but not in adults. CONCLUSIONS: Using the testing conditions of the present study, increasing stimulus size beyond the largest used in a Goldmann perimeter (approximately 2 degrees) increases measured visual field extent in young infants, but not in adults. This may relate to differences in peripheral summation areas or to differences in attentional factors between infants and adults.     

Learning to Observe Relationships and Coping

Milieu relationships provide the critical background presence to staff's attempts to motivate, regulate, and teach patients how to cope with stress. Forging a connection with hospitalized children and adolescents demands attention to how they respond to adults and engage with staff around milieu expectations. Assessment guides that deal with these issues are presented. Important aspects of children's relatedness are presented in the context of their working models of adults and the influence of these representations on their response to staff. Coping skills are explained with particular emphasis on behavioral coping strategies. Tied to the assessment process are interventions that emphasize staff's role in helping patients manage strong affects and avoid the use of nonproductive behavior regulation strategies.     

Effects of Ro 15-4513 on schedule-controlled responding of pigeons

The partial inverse benzodiazepine agonist Ro 15-4513 has been found to antagonize some of the behavioral and physiological effects of ethanol, but relatively little is known about the behavioral effects of the drug alone. In the present study, pigeons responding under a multiple fixed-ratio 25 interresponse-time-greater-than-6-sec schedule of food delivery were exposed acutely and chronically to Ro 15-4513. Acute administrations of the drug (1.0, 1.8, 3.2, and 5.4 mg/kg) reduced response rates under the fixed-ratio component at some doses, although two birds were more sensitive to the drug than the third subject. Response rates under the interresponse-time-greater-than-6-sec component were not affected by acute administrations of Ro 15-4513. When 5.4 mg/kg Ro 15-4513 was administered prior to 15 consecutive sessions, tolerance developed to the rate-reducing effects of the drug under the fixed-ratio component. These findings, in contrast to those of early investigations in which gross measures of behavior were employed, suggest that Ro 15-4513 is behaviorally active at relatively low doses.     

RN-BSN programs: associate degree and diploma nurses' perceptions of the benefits and barriers to returning to school.

The nursing profession is facing a serious shortage in all areas including BSN completion programs. The purpose of this study was to explore associate degree and diploma nurses' perceptions of the benefits and barriers to RN-BSN programs. In addition, factors that would facilitate degree completion in academia and work environments were examined.
