Content of zinc, iron and their absorption inhibitors in Nicaraguan common beans (Phaseolus vulgaris L.).

Common bean (Phaseolus vulgaris L.), the staple crop of Nicaragua, provides protein and nonhaem iron, but inhibitors such as phytate may prevent absorption of iron and zinc by the consumer. Warehouses in Nicaragua do not have controlled atmospheres, so beans are exposed to high temperatures and humidities that may accelerate quality loss. To evaluate the impact of 6months of storage on quality, four national accessions of common bean were submitted to two treatments, a conventional warehouse with uncontrolled temperature and humidity, and accelerated ageing at 40°C and 75% RH. Iron content was 61-81mg/kg of which 3-4% was bioavailable, and zinc content was 21-25mg/kg, of which 10-12% was bioavailable. Bioavailability generally increased in storage, significantly so in year-old INTA Linea 628 in accelerated ageing. The concentration of phytate was 8.6-9.6mg/g and it contained 54-63% of the total phosphorus. Improvement in bioavailability of divalent cations is needed.

Treatment of pain in acutely burned children.

The child with burns suffers severe pain at the time of the burn and during subsequent treatment and rehabilitation. Pain has adverse physiological and emotional effects, and research suggests that pain management is an important factor in better outcomes. There is increasing understanding of the private experience of pain, and how children benefit from honest preparation for procedures. Developmentally appropriate and culturally sensitive pain assessment, pain relief, and reevaluation have improved, becoming essential in treatment. Pharmacological treatment is primary, strengthened by new concepts from neurobiology, clinical science, and the introduction of more effective drugs with fewer adverse side effects and less toxicity. Empirical evaluation of various hypnotic, cognitive, behavioral, and sensory treatment methods is advancing. Multidisciplinary assessment helps to integrate psychological and pharmacological pain-relieving interventions to reduce emotional and mental stress, and family stress as well. Optimal care encourages burn teams to integrate pain guidelines into protocols and critical pathways for improved care.

Ten-year research review of physical injuries.

OBJECTIVE: To review the past 10 years of research relevant to psychiatry on injuries in children and adolescents. METHOD: A literature search of databases for "wounds and injuries, excluding head injuries," was done with Medline and PsycINFO, yielding 589 and 299 citations, respectively. Further searching identified additional studies. RESULTS: Progress is occurring in prevention, pain management, acute care, psychiatric treatment, and outcomes. The emotional and behavioral effects of injuries contribute to morbidity and mortality. Psychiatric assessment, crisis intervention, psychotherapy, psychopharmacological treatment, and interventions for families are now priorities. Research offers new interventions for pain, delirium, posttraumatic stress disorder, depression, prior maltreatment, substance abuse, disruptive behavior, and end-of-life care. High-risk subgroups are infants, adolescents, maltreated children, suicide attempters, and substance abusers. Staff training improves quality of care and reduces staff stress. CONCLUSIONS: Despite the high priority that injuries receive in pediatric research and treatment, psychiatric aspects are neglected. There is a need for assessment and for planning of psychotherapeutic, psychopharmacological, and multimodal treatments, based on severity of injury, comorbid psychopathology, bodily location(s), and prognosis. Psychiatric collaboration with emergency, trauma, and rehabilitation teams enhances medical care. Research should focus on alleviating pain, early psychiatric case identification, and treatment of children, adolescents, and their families, to prevent further injuries and reduce disability.

Relationship between acute morphine and the course of PTSD in children with burns.

OBJECTIVE: To investigate the relationship between the dose of morphine administered during a child's hospitalization for an acute burn and the course of posttraumatic stress disorder (PTSD) symptoms over the 6-month period following discharge from the hospital. METHOD: Twenty-four children admitted to the hospital for an acute burn were assessed twice with the Child PTSD Reaction Index: while in the hospital and 6 months after discharge. The Colored Analogue Pain Scale was also administered during the hospitalization. All patients received morphine while in the hospital. The mean dose of morphine (mg/kg/day) was calculated for each subject through chart review. RESULTS: The Pearson product moment correlation revealed a significant association between the dose of morphine received while in the hospital and a 6-month reduction in PTSD symptoms. Children receiving higher doses of morphine had a greater reduction in PTSD symptoms over 6 months. CONCLUSIONS: This study suggests the possibility that acute treatment with morphine can secondarily prevent PTSD. This result is discussed in terms of the possible effect of morphine on fear conditioning and the consolidation of traumatic memory.

Management of background pain and anxiety in critically burned children requiring protracted mechanical ventilation.

Optimal control of pain and anxiety is an elusive but important goal in children with protracted critical illness. This review represents an effort to document the doses of background medication required to achieve this goal in a group of children managed under a pain and anxiety protocol that adjusts background infusions to comfort. The course of children with wounds involving at least 10% of the body surface and coincident respiratory failure requiring mechanical ventilation for more than 7 days managed 1 Jan 97 to 31 Dec 98 was reviewed. A pain and anxiety protocol was used, including background infusions of morphine and midazolam adjusted to comfort. These 28 children had a mean (+/- standard deviation) age of 5.3 +/- 4.6 years, wound size of 48.3 +/- 28.4%, and were intubated for 25.0 +/- 23.9 days. Neuromuscular blocking drugs were administered for 65 of 447 (14.5%) ventilator days. To maintain comfort, drugs were required at doses substantially above standard dosing schemes. The highest daily background infusion of morphine sulfate averaged 0.40 mg/kg/hr +/- 0.24 mg/kg/hr (usual starting dose was 0.05 to 0.1 mg/kg/hr) and was reached 14.1 +/- 12.8 days after admission. The highest daily background infusion of midazolam averaged 0.15 +/- 0.07 mg/kg/hr (usual starting dose was 0.04 mg/kg/hr) and was reached 14.0 +/- 3.8 days after admission. Morphine infusions at extubation averaged 0.22 +/- 0.17 mg/kg/hr and midazolam infusions 0.10 +/- 0.12 mg/kg/hr. All children survived to discharge and there was no perceived morbidity related to these high doses of medication. Children with serious burns and respiratory failure will require high doses of background opiates and benzodiazepines to remain comfortable, because they develop drug tolerance during protracted critical illness. Infusions can be continued at a reduced dose through extubation, do not result in addiction or other apparent morbidity if adjusted to desired level of comfort, and may contribute to a reduced incidence of treatment-related stress disorders.

Treatment-resistant pain and distress during pediatric burn-dressing changes.

Recent research has suggested some efficacy for the use of hypnosis in the control of pain and distress in a pediatric population undergoing painful medical procedures. Here, we study a sample (N=23) of pediatric subjects undergoing burn-dressing changes and receiving either an imagery-based or control (social-support) treatment. Subjects' levels of distress were assessed with the Observational Scale of Behavioral Distress. Results indicated that distress behaviors in this population can be measured reliably using this scale. However, no support was found for the main hypothesis that imagery treatment would be superior to control treatment in the alleviation of distress, nor were these treatments effective in comparison to baseline conditions. We discuss the formidable problem that burn and dressing-change pain presents, as well as the reasons why this treatment attempt might have failed to have the predicted effects. We also discuss important developmental considerations regarding the adequate assessment of pain and distress.

A rapid antibody-based test for Sec-2, a marker for the short arm of chromosome 2 of rye (2RS).

A simple monoclonal antibody-based screening test has been developed for the presence of translocations of the short arm of chromosome 2 of rye (2RS) with wheat chromosome 2B. 2RS encodes a set of about three polypeptides known as Mr 75 000 gamma-secalins. Use of the antibody test for these secalins enabled screening of several hundred seeds per day. The antibody could readily distinguish 2BL-2RS translocations and 2R substitutions from 1BL-1RS translocations or nontranslocation wheats. Use of the antibody in analysis of segregating progeny for Sec-2 in several wheat backgrounds was successful. Results with a selection of the seed population were checked using protein gel electrophoresis, with 100% correct confirmation. Key words : rye, wheat, seed proteins, translocation, diagnostic test.

Parent participation during burn debridement in relation to behavioral distress.

The data on the benefits of parent participation during pediatric medical procedures are mixed. Although a wealth of clinical experience and survey data strongly recommend parent participation in a child's medical care, the mere presence of a parent, particularly during medical procedures, may be insufficient to decrease behavioral distress. This study examined a sample of children aged 3 through 12 undergoing three successive burn dressing changes. For some sessions, parents were present, and for others, they were not. A valid and reliable measure of behavioral distress was taken, as was an informal measure of the level of parent participation. Results indicated no differences between mothers and fathers in the level or the nature of participation, little change in the level of participation across time, and higher levels of physical comforting than verbal comforting. Results also indicated higher levels of behavioral distress in subjects when parents were present versus when absent, which extends previous findings. Results are discussed in terms of the literature on parent and child preferences for parent involvement and parent coaching programs.

Midazolam infusion in pediatric patients with burns who are undergoing mechanical ventilation.

Adequate sedation is an integral component of mechanical ventilation. To document the safety and efficacy of midazolam infusion in pediatric patients with burns who were undergoing mechanical ventilation, a retrospective review was done of all patients requiring mechanical ventilation over a 22-month period. Twenty-four acutely burned pediatric patients required mechanical ventilation. The average age was 6.4 years (range 7 months to 12 years), and the average burn size was 50% of the body surface (range 40% to 95%). Midazolam infusion was initiated at an average dose of 0.045 mg/kg/hr (range 0.01 to 0.09 mg/kg/hr). The maximum dose administered averaged 0.11 mg/kg/hr (range 0.04 to 0.35 mg/kg/hr). The duration of infusion averaged 16.5 days (range 4 to 56 days). All patients received simultaneous infusions of morphine sulfate. Midazolam infusion was titrated to achieve a diminished narcotic requirement, decreased anxiety, and better tolerance of dressing changes. No hypotension or problems weaning from mechanical ventilation were seen. Two (8.3%) children experienced reversible neurologic abnormalities attributed to midazolam infusion but made full neurologic recoveries. In conclusion, our experience with midazolam infusion in pediatric patients with burns who were undergoing mechanical ventilation is favorable and supports its continued use.

Primary nursing: psychological implications.

Even with the decreasing lengths of stay, primary nurses and their patients become attached. These issues of "involvement" can be sources of stress and can complicate primary nursing. Recognizing psychological issues leads to greater job satisfaction and professional identity.

Posttraumatic stress disorder in mothers of children and adolescents with burns.

This is the first study of of posttraumatic stress symptoms in parents (24 mothers and one father) of children with burns. The purpose of the study was to determine what factors relate to parental posttraumatic stress disorder (PTSD). Because the sample is all mothers, except for one father, the conclusions are about mothers. Through use of the Structured Clinical Interview for DSM-III-R, symptoms were determined as occurring from the time of the burn injury until 1 month before the interview (past), 1 month before the interview only (present), or from the date of the burn trauma up to and including 1 month before the interview (past and present). By Structural Clinical Interview criteria, 52% of the mothers had past PTSD, with four (31%) of those mothers having present PTSD symptoms. Eleven mothers and the one father reported neither past nor present PTSD. Multiple regression analysis revealed that larger burns were more strongly related to present PTSD symptoms than were proximity, social support, or perceived stress. Additional findings indicated that mothers with more than one child burned and those mothers who were burned themselves met diagnostic criteria for PTSD. Implications are that posttraumatic stress symptoms can be disruptive to a mother feeling capable of caring for her child with burns after the injury. Individual and group therapy during and after a child's hospitalization may be useful for mothers to reduce stress and to develop better coping skills.

A case of functional urinary retention: the use of family play therapy.

This case presents a technique for doing family therapy in families with young children. In family play therapy, the entire family plays together, allowing full participation of even the youngest children in the therapeutic process. Standard family therapy interventions in the latter part of each session make use of family interaction patterns and unconscious processes revealed during the earlier play. In the case presented here, the technique was successfully applied to a family with a 3-year-old son who had functional urinary retention. This case also provided an opportunity for interdisciplinary collaboration between the separate Child and Family Services at a major teaching hospital.

Depression in children after recovery from severe burns.

This outcome study of children and adolescents with severe burns (ages 7 to 19 years) reports that unrecognized depression is common during their lifetimes. Thirty children who had severe burns (range, 5% to 95% body surface area) were assessed for depression at a mean of 9 years after burn injury. This article presents an analysis of depression items from the Diagnostic Interview for Children and Adolescents, which was used in face-to-face interviews to assess child psychiatric disorders with diagnostic criteria from the American Psychiatric Association's Diagnostic and Statistical Manual--Third Edition. At the time that the interviews took place, only one child had symptoms of major depression and only three children had symptoms of dysthymic disorder. However, eight children had a lifetime history of major depression; two of them had been abused by burning and two had been physically or sexually abused. Four had made suicide attempts: one suicide attempt was the cause of the burn injury and three attempts were made after burn injury. Thirteen children had had suicidal thoughts, and their parents were often unaware of this. Other types of affective disorders were prevalent. There was no statistically significant association between depression and burn size or disfigurement. Although burn-related factors were associated with some depressive episodes, other biologic and social risk factors were also very important. The authors conclude that referral for diagnostic services and psychotherapy, and for some, treatment with antidepressant medication, is often a necessary part of medical services for children with burns.

Psychiatric outcome of burned children and adolescents.

Recent medical and surgical advances allow many severely burned patients to survive who formally would have died. Assessment of psychiatric outcomes with these patients may provide ways of measuring effects of acute burn care methods on later quality of life, specify more accurately their emotional needs during rehabilitation, and stimulate further research. Thirty children, aged 7 to 19, with severe burns are compared with 30 nonburned subjects matched for age, sex, SES, and parents' marital status according to DSM-III criteria. The burned children had significantly higher levels of overanxious disorder, phobias, and enuresis, but they had the same rates of present depressive disorders.

A diagnostic outcome study of children and adolescents with severe burns.

The results of a diagnostic outcome study of children and adolescents with severe burns are presented. The positive research findings include evidence of present and lifetime full and partial anxiety and depressive disorders and statistically significant within-sample, burn-related, and demographic differences. The negative findings are less depression and post-traumatic stress disorder by DSM-III criteria than expected, the presence of a subgroup of severely burned children who appeared to be functioning well with only a few or no diagnoses, and absence of significant differences on many variables on within-group comparisons. Based on these data, periodic psychiatric evaluation or reevaluation and specifically targeted followup treatment are indicated for many burned children, adolescents, and their families.

Psychiatric benefits and insurance regulation in Massachusetts: a national model?

The Massachusetts Mandatory Mental Health Insurance Act requires all health insurance plans in the state to cover mental illness. Because of their concerns that this law might be taken as a national model, the authors describe the problems encountered in implementing it and the conflicts between the insurance carriers and psychiatry. The authors attribute the problems to some insurance carriers' failure to deal directly with organized psychiatry in obtaining screening guidelines, the absence of psychiatrists on the carriers' central committees, and psychiatrists' generally indifferent and hostile attitudes toward the carriers. The authors describe recent improvements and recommendations based on 10 years of experience.
