RESUMO

We sought to establish guidelines for hygiene care in newborns based on a systematic review of the literature and grading of evidence using the Groupe de Réflexion et d'Evaluation de l'Environement des Nouveau-nés (GREEN) methodology. We examined 45 articles and 4 reports from safety agencies. These studies recommend a tub bath (rather than a sponge bath) for full-term infants and a swaddle bath for preterm newborns. They also recommend against daily cleansing of preterm infants. The literature emphasized that hygiene care must consider the clinical state of the newborn, including the level of awareness and behavioral responses. Hospitalized newborns treated with topical agents may also experience high exposure to potentially harmful excipients of interest. Caregivers should therefore be aware of the excipients present in the different products they use. In high-resource countries, the available data do not support the use of protective topical agents for preterm infants.Conclusions: We recommend individualization of hygiene care for newborns. There is increasing concern regarding the safety of excipients in topical agents that are used in neonatology. A multidisciplinary approach should be used to identify an approach that requires lower levels of excipients and alternative excipients. What is known: • Hygiene care is one of the most basic and widespread types of care received by healthy and sick newborns worldwide. • There is no current guideline on hygiene for preterm or hospitalized term newborn. What is new: • The French Group of Reflection and Evaluation of the environment of Newborns (GREEN) provided here guidelines based on the current body of evidence. • Caregivers should be aware of the many issues related to hygiene care of newborns including newborns' behavioral responses to hygiene care, exposition to excipients of interest, and the potential risk of protective topical agents in a preterm infant. provided here guidelines based on the current body of evidence. • Caregivers should be aware of the many issues related to hygiene care of newborns including newborns' possible behavioral responses to hygiene care, exposition to excipients of interest and the potential risk of protective topical agents in a preterm infant.

RESUMO

BACKGROUND: Patent ductus arteriosus is a common complication of prematurity that frequently requires surgical or medical treatment. The benefit of prophylactic treatment by indometacin, a cyclo-oxygenase inhibitor, remains uncertain compared with curative treatment. This benefit could be improved with ibuprofen, another cyclo-oxygenase inhibitor with fewer adverse effects than indometacin on renal, mesenteric, and cerebral perfusion. We aimed to compare prophylactic and curative ibuprofen in the treatment of this abnormality in very premature infants. METHODS: We did a randomised controlled trial in infants younger than 28 weeks of gestation, who were randomly assigned to receive either three doses of ibuprofen or placebo within 6 h of birth. After day 3, symptomatic patent ductus arteriosus was treated first by open curative ibuprofen, then back-up indometacin, surgery, or both. The primary endpoint was need for surgical ligation. Analysis was per protocol. FINDINGS: The study was stopped prematurely after 135 enrollments because of three cases of severe pulmonary hypertension in the prophylactic group. 65 infants received prophylactic ibuprofen, and 66 received placebo. Prophylaxis reduced the need for surgical ligation from six (9%) to zero (p=0.03), and decreased the rate of severe intraventricular haemorrhage from 15 (23%) to seven (11%) (p=0.10). However, survival was not improved (47 [71%] placebo vs 47 [72%] treatment, p=1.00), because of high frequency of adverse respiratory, renal, and digestive events. INTERPRETATION: In premature infants, prophylactic ibuprofen reduces the need for surgical ligation of patent ductus arteriosus, but does not reduce mortality or morbidity. Therefore, it should not be preferred to early curative ibuprofen.

RESUMO

OBJECTIVE: This research assessed whether the outcome of schizoaffective disorder is more similar to that of schizophrenia or that of affective disorders. METHOD: The authors conducted a prospective follow-up study of 101 schizoaffective, schizophrenic, bipolar manic, and depressed patients assessed at three times: during hospitalization and 2 and 4-5 years later. The follow-up test battery involved detailed assessment of social functioning, work performance, symptoms, posthospital treatment, and rehospitalization. RESULTS: Outcome for schizoaffective patients 4-5 years after hospitalization differed significantly from that for patients with unipolar depression. However, the differences between schizoaffective and bipolar manic patients were more equivocal. Unlike the patients with bipolar disorder, only a limited number of patients with schizoaffective disorder showed complete recovery in all areas throughout the year preceding the 2-year follow-up and the year preceding the 4- to 5-year follow-up. The differences in outcome between schizoaffective and schizophrenic patients were also mixed. These two groups showed some similarities in outcome, but there were fewer schizoaffective than schizophrenic patients with uniformly poor outcome in all areas. CONCLUSIONS: Overall, schizoaffective patients showed some similarities to both schizophrenic and bipolar manic patients. Schizoaffective patients had somewhat better overall posthospital functioning than patients with schizophrenia, somewhat poorer functioning than bipolar manic patients, and significantly poorer functioning than patients with unipolar depression. The data suggest that when mood-incongruent, schizophrenic-like psychotic symptoms are present in the acute phase, they predict considerable difficulty in outcome, even when affective syndromes are also present, as in schizoaffective disorder. It is likely that schizoaffective disorder is not just a simple variety of affective disorder.

RESUMO

The authors assessed cyclothymic mood swings and psychosocial adjustment in 38 unipolar depressed, 27 bipolar, 35 schizophrenic, and 27 other psychiatric patients 4 years after hospital discharge and in 153 normal control subjects. The patients were significantly more cyclothymic at follow-up than the control subjects, but there were no differences in cyclothymia between the diagnostic groups. Cyclothymic patients showed significantly poorer posthospital functioning than noncyclothymic patients. These findings raise questions concerning the scope of the hypothesized cyclothymic-bipolar spectrum. Minor mood swings in a variety of patients with poor posthospital adjustment may reflect persistent vulnerability to psychopathology.

RESUMO

Rats were made obese by VMH knife-cuts and then a 5 or 10 cm segment of terminal ileum was transposed to the duodenum. After surgery, the food moved from the stomach into upper duodenum and then traveled through the transposed ileal segment to lower duodenum and continued down the remaining normal digestive tract. Ileal transposition caused a significant reduction in food intake and a substantial loss of body weight. There was no difference in weight loss with 5 and 10 cm ileal transpositions in obese rats, but weight loss was much less in lean rats. Weight loss was accompanied by a considerable loss in dissectable body fat and an increase in the actual weight of the pancreas and small intestine. These changes are probably caused by the unusual stimulation of a short segment of terminal ileum with undigested food and pancreatic enzymes and may have been mediated by the release of ileal hormones. Changes in plasma levels of metabolites, intracellular enzymes, and protein are presented and the importance of this surgery for the treatment of human obesity is evaluated.

RESUMO

Recent open clinical trials have found the selective serotonin reuptake inhibitor (SSRI) fluoxetine to be beneficial in the treatment of posttraumatic stress disorder (PTSD) symptoms. We have reported previously that the binding of a newer SSRI, paroxetine, to blood platelets is decreased in PTSD patients compared to normal control subjects. In the current study, pretreatment platelet paroxetine binding data were analyzed for ten Vietnam combat veterans who were treated clinically with fluoxetine for PTSD, diagnosed on the basis of the Structured Clinical Interview for DSM-III-R. Specific binding of 3H-paroxetine is reported in terms of the dissociation constant (Kd) and the maximum density of binding sites (Bmax). Based on our previous findings we hypothesized that decreased platelet 3H-paroxetine binding would be associated with positive therapeutic response to subsequent treatment with fluoxetine. Global clinical improvement ratings, conducted blind to the biochemical data, were used to separate patients into five maximal responders and five partial responders. The results indicated that maximal responders had lower pretreatment Kd values (p = .016) and a trend toward lower pretreatment Bmax values (p = .075) than the partial responders. These preliminary findings may warrant further study of platelet SSRI binding as a possible predictor of SSRI treatment response in PTSD patients.

RESUMO

We have previously reported that binding to blood platelets of paroxetine, a selective serotonin (5-HT) reuptake inhibitor which binds to 5-HT uptake sites, is decreased in patients with posttraumatic stress disorder (PTSD). Specifically, we found a lower number of platelet 3H-paroxetine binding sites (Bmax) and a lower dissociation constant (Kd) for 3H-paroxetine binding in combat veterans with PTSD compared to normal control subjects. In the current study we assessed the relationship of platelet 3H-paroxetine binding to clinical features in 41 Vietnam combat veterans with SCID-diagnosed PTSD. The results indicated that Bmax of platelet 3H-paroxetine binding was negatively correlated with both state and trait anxiety, as well as with depressive and overall PTSD symptoms. However, there was no evidence that platelet 3H-paroxetine binding differed as a function of comorbid psychiatric diagnoses including major depression, other anxiety disorders, and substance abuse in these patients.

RESUMO

Platelet serotonin (5-HT) uptake, as determined by 3H-paroxetine (PA) binding, was studied in 20 Post-traumatic Stress Disorder (PTSD) patients and 20 normal controls. Kd (an inverse measure of affinity of 3H-PA binding to uptake sites) and Bmax (maximum number of 3H-PA binding sites) of 3H-PA binding were significantly decreased in PTSD patients as compared to normal controls. However, there was no difference in Kd or Bmax between PTSD patients with and without a diagnosis of major depression. The Bmax of 3H-PA binding was negatively correlated with state dependent anxiety score whereas Kd was positively correlated with the Mississippi Scale for Combat-Related PTSD score. The role of serotonergic processes in the psychobiology of PTSD is discussed.

RESUMO

The present study was designed to investigate the relationships between expression, perception, and experience of emotion in schizophrenic patients with and without affective blunting. Cognitive processing speed, emotional perception, and emotional experience were assessed in 25 schizophrenic patients grouped according to scores on a measure of overt emotional expression (Rating Scale for Emotional Blunting). Results showed dissociation of emotional expression from emotional perception and emotional experience. Blunted schizophrenic patients were no more impaired in the perception of emotion (Profile of Nonverbal Sensitivity) than non-blunted schizophrenic patients. In addition, groups did not differ in intensity of emotional experience as quantified on the self-report of arousal state (Positive and Negative Affect Scales). Accuracy of perception and reported experience of emotion did not differ between groups as a function of emotional valence. Cognitive processing speed (Symbol Digit Modalities Test; SDMT) was related to blunting score and to perception accuracy, although the SDMT did not differ between groups. Results are discussed in terms of a neuropathological basis for impairment of emotional expression.

RESUMO

Brain maps were recorded on a patient with a multiple personality disorder (10 alternate personalities). Maps were recorded with eyes open and eyes closed during 2 different sessions, 2 months apart. Maps from each alternate personality were compared to those of the basic personality "S", some maps were similar and some were different, especially with eyes open. Findings that were replicated in the second session showed differences from 4 personalities, especially in theta and beta 2 frequencies on the left temporal and right posterior regions. A rank ordering of the differences in the brain maps of the alternate personalities from S were similar to the rank ordering of the differences in personality characteristics, as judged by the psychiatrist dealing with this patient. Maps from S acting like some of her personalities or from a professional actress portraying the different personalities did not reveal significant differences. Some of these findings are consistent with those in the literature, and the importance of detecting artifact in the raw EEG recording is emphasized.

RESUMO

OBJECTIVE: Recent legislation in several states providing for civil commitment and preventive detention of sexually violent persons has stirred legal, clinical, and public policy controversies. The mandate for psychiatric evaluation and treatment has an impact on public mental health systems, requiring clinicians and public administrators to direct attention to treatment options. It is a common view that no treatments work for disorders involving sexual aggression. The authors examine this assumption by reviewing research on the effectiveness of treatment for adult male sex offenders. METHODS: MEDLINE was searched for key reviews and papers published during the years 1970 through 1998 that presented outcome data for sex offenders in treatment programs, individual case reports, and other clinically and theoretically important information. RESULTS: Although rigorous research designs are difficult to achieve, studies comparing treated and untreated sex offenders have been done. Measurement of outcome is flawed, with recidivism rates underestimating actual recurrence of the pathological behavior. Outcome research suggests a reduction in recidivism of 30 percent over seven years, with comparable effectiveness for hormonal and cognitive-behavioral treatments. Institutionally based treatment is associated with poorer outcome than outpatient treatment, and the nature of the offender's criminal record is an important prognostic factor. CONCLUSIONS: Although treatment does not eliminate sexual crime, research supports the view that treatment can decrease sex offense and protect potential victims. However, given the limitations in scientific knowledge and accuracy of outcome data, as well as the potential high human costs of prognostic uncertainty, any commitment to a social project substituting treatment for imprisonment of sexual aggressors must be accompanied by vigorous research.

RESUMO

OBJECTIVE: Clozapine has been shown to be a cost-effective treatment for refractory psychosis among patients started on the medication in a hospital setting. The study examined service utilization and costs associated with clozapine treatment initiated in an outpatient clinic. METHODS: Subjects (N=28) included adult patients with a diagnosis of schizophrenia or schizoaffective disorder who began their clozapine treatment at an urban community mental health center. Subjects' charts were reviewed for information on service utilization in the year before and after starting clozapine, using an intent-to-treat approach. Hospitalization information was cross-checked against the Illinois Department of Human Services database. Costs were computed for hospitalization, medication, community outpatient services, and housing. RESULTS: Subjects' mean rate of hospitalization was reduced by more than half during the clozapine treatment year, and the mean number of days in the hospital decreased by more than two-thirds, from 23.5 days to 7.6 days. Mean hospitalization costs were reduced by more than half. Mean annual costs of medication rose from $648 in the year before clozapine treatment to $6,760 during the clozapine treatment year. Cost increases for medication, community services, and housing led to a marginal increase in the total cost of treatment. CONCLUSIONS: Patients initiating clozapine treatment on an outpatient basis showed a pattern of decreased hospitalization during the first year on clozapine. The cost savings associated with decreased hospitalization substantially, though not fully, offset the increased expense of clozapine during the first year of community-based treatment.

RESUMO

Using computerized pharmacy, laboratory, and hospitalization data from a large state psychiatric hospital system, this study examined physician responses to laboratory studies obtained in the course of therapeutic drug monitoring. Computerized monitoring modules based on physician-developed guidelines identified out-of-range laboratory values and searched for appropriate corresponding physician responses within clinically driven, mathematically adjusted time frames. Valproate monitoring in four metropolitan hospitals showed that appropriate physician responses were associated with shorter hospital stays for patients and were predictive of length of stay in a multiple regression analysis (p<.001). After physicians received didactic feedback, the percentage of appropriate responses to low serum valproate levels increased.

RESUMO

OBJECTIVE: The authors describe a self-assessment training program for multidisciplinary mental health teams that was developed in a public multihospital system, the process of implementing the training at a state psychiatric hospital, and a measurement instrument, the Scale for Leadership Assessment and Team Evaluation (SLATE), which they have used for self-assessment of multidisciplinary teams and which is currently being studied. They assessed whether changes in team self-assessments could be seen after the training program. METHODS: A total of 102 mental health professionals from 12 inpatient units representing the disciplines of psychiatry, psychology, nursing, social work, and occupational and activity therapy completed the SLATE before and after participation in a training program that consisted primarily of team self-assessment in the context of treatment planning sessions. The training program included structured feedback, didactics, consultation, and videotaping of sessions. Aggregate data were used to compare mean item scores for the SLATE overall and for its four subscales (team, psychiatrist, participation, and treatment plan) at baseline and after the training. RESULTS: Scores increased significantly for the overall SLATE and for all four subscales, indicating improved team functioning in the areas addressed. The increase in mean score was greatest for the subscale that assessed the leadership of the psychiatrist. CONCLUSIONS: Treatment planning sessions can be used successfully by multidisciplinary mental health teams to examine team functioning in various areas in a self-assessment model. Participation in a training program that included videotaping of sessions, consultation, and structured attention to team functioning was associated with improved ratings of team functioning.

RESUMO

Given current assumptions about the biology of neural organization, some connectionists believe that it may not be possible to accurately model the brain's neural architecture. We have identified five restrictive neurobiological dogmas that we believe have limited the exploration of more fundamental correlations between computational and biological neural networks. We postulate that: 1) the dendritic tree serves as a synapse storage device rather than a simple summation device; 2) connection strength between neurons depends on the number and location of synapses of similar weight, not on synapses of variable weights; 3) axonal sprouting occurs regularly in adult organisms; 4) the postsynaptic genome directly controls the presynaptic cell via mRNA, rather than indirectly by the expression of NCAMs, reverse neurotransmitters, etc.; 5) dendritic spines serve a trophic function by controlling development of new sprouts via a process we term retroduction. We entertain an alternative formulation of a computational neural element that is fully consistent with modern neuroscience research. We then show how our model neuron can learn under Hebbian conditions, and extend the model to explain non-Hebbian, one-trial learning. This work is significant because by stretching the theoretical boundaries of modern neuroscience, we show how connectionists can potentially create new, more biologically-based neural elements which, when, interconnected into networks, exhibit not only properties of existing backpropagation networks, but other physiological properties as well.

RESUMO

While blood pressure measurement methods in infants are well established, hypertension, a rare disease in this population, may still be revealed by heart failure. Kidney diseases are the most common causes of hypertension, prompting the search for a renovascular cause to start appropriate treatment. We report on 2 cases of late diagnosis of hypertension in infants, with hypertensive cardiomyopathy, one in the context of autosomal recessive polycystic kidney disease and the other in the context of renal artery stenosis with hemodynamic disorder, hypertensive encephalopathy and neurological sequelae. In both cases, the equilibrium of blood pressure was difficult to achieve in the acute phase. Renal ultrasound is fundamental for diagnosis. The potential complications related to hypertension require early diagnosis, emphasizing the importance of measuring blood pressure during a routine consultation in infants.
