[Use of cognitive aids in pediatric emergency care : Interdisciplinary consensus statement]. / Anwendung kognitiver Hilfsmittel im Kindernotfall : Interdisziplinär konsentierte Stellungnahme.

Preclinical pediatric emergencies are rare events and are therefore often associated with stress and uncertainty for emergency medical service personnel. To ensure adequate treatment of pediatric patients a variety of different cognitive aids exist (e.g. books, apps, rulers, weight-adapted bag systems). Especially the size specifications of the medical equipment and the dosage of emergency medication are individually very different in children and are dependent on parameters, such as body height and weight. Therefore, cognitive aids often enable length measurement whereby it is possible to draw conclusions on body weight for calculating the child's medication dosage. These aids may help to avoid the wrong medication dose or the wrong therapy of children but uncritical and untrained usage of these aids carries a potential risk of mistakes. This recommendation gives an overview of the general requirements and different problems of cognitive aids and should help improve the general framework and the rational basis for the use and further development of cognitive aids in emergency medicine.

Effect of grinding intensity and feed physical form on in vitro adhesion of Salmonella Typhimurium and mannose residues in intestinal mucus receptors for salmonellae.

The hypothesis of this study was that feeding a fine, pelleted diet (FP) compared to a coarse meal diet (CM) results in a higher mannose content in the intestinal mucus of pigs and therefore an increased in vitro adhesion of Salmonella Typhimurium DT104 L to the mucus. The 2 diets were fed to a total of 24 weaned pigs for 6 wk after which mannose content in the mucus was evaluated histochemically using the α1-3-d-mannose-specific lectin Galanthus nivalis agglutinin. The crypt width was determined as an indirect measure for the amount of secreted mucus. Ileal and cecal tissue samples were incubated with approximately 7.77 × 10(7) cfu Salmonella Typhimurium and numbers of salmonellae adhering to the mucus and/or mucosa were determined by culture techniques. There was no effect of feed physical form on the in vitro adhesion of S. Typhimurium either in the ileum (7.1 ± 0.19 log(10) cfu/g tissue) or in the cecum (6.8 ± 0.26 log(10) cfu/g). The mannose content of the mucus also did not differ between the treatment groups. The crypts of the duodenum, jejunum, and cecum were wider (P < 0.05) after feeding the CM diet. This might be an indication for a higher mucus production in these pigs.

Changes in the process of care for Medicaid patients with schizophrenia in Utah's Prepaid Mental Health Plan.

OBJECTIVE: Changes in the process of psychiatric care received by Medicaid beneficiaries with schizophrenia were examined after the introduction of capitated payments for enrollees of some community mental health centers (CMHCs) under the Utah Prepaid Mental Health Plan. METHODS: Data from the medical records of 200 patients receiving care in CMHCs participating in the prepaid plan were compared with data from the records of 200 patients in nonparticipating CMHCs, which remained in a fee-for-service reimbursement arrangement. Using the Process of Care Review Form, trained abstracters gathered data characterizing general patient management, social support, medication management, and medical management before implementation of the plan in 1990 and for three follow-up years. Using regression techniques, differences in the adjusted changes between third-year follow-up and baseline were examined by treatment site. RESULTS: By year 3 at the CMHCs participating in the plan, psychotherapy visits decreased, the probability of a patient's terminating treatment or being lost to follow-up increased, the probability of having a case manager increased, the probability of a crisis visit decreased (but still exceeded that at the nonplan sites), and the probability of treatment for a month or longer with a suboptimal dosage of antipsychotic medication increased. Only modest changes in the process of care were observed at the nonplan CMHCs. CONCLUSIONS: Change in the process of psychiatric care was more evident at the sites participating in the plan, where traditional therapeutic encounters were de-emphasized in response to capitation. The array of changes raises questions about the vigor of care provided to a highly vulnerable group of patients.

An instrument to evaluate the process of psychiatric care in ambulatory settings.

As part of an evaluation of the Utah Prepaid Mental Health Plan, the Process of Care Review Form was developed to assess the quality of the process of psychiatric care provided by Utah's community mental health centers (CMHCs) to clients with schizophrenia. This article briefly reviews issues in the measurement of quality of care and describes the development and implementation of the form. The 67-item form was designed for use by a trained abstracter to gather data from CMHC medical records in six areas: general management of the patient, medication management, medical management, social support, psychiatric hospitalization, and psychiatric assessment. A 59-item version of the form that omits the section on psychiatric assessment has been used in three waves of data collection to document data spanning five years (1990-1994) in the evaluation of the process of psychiatric care in the Utah plan. It is currently being used longitudinally to examine differences between Utah CMHCs receiving capitated payments and those paid on a fee-for-service basis by Medicaid.

Cognitive slowing and working memory difficulties in chronic fatigue syndrome.

OBJECTIVE: Patients with chronic fatigue syndrome (CFS) commonly report problems with attention, memory, learning, and speed of cognitive processing. This study attempted to evaluate these complaints using objective test criteria. METHOD: A test battery composed of six tests assessing these cognitive functions was given on two consecutive days. Twenty CFS patients were compared with 20 healthy control subjects and 14 patients with a history of major depression or dysthymia matched by age, intelligence, education level, and sex. RESULTS: Compared with control subjects, CFS patients consistently scored lower on tests in which motor and cognitive processing speeds were a critical factor, eg, reaction-time tasks. They also had more difficulty on working-memory tests in which rapid cognitive processing speed is also an important factor. The effort made on the first day of testing did not result in a decline in cognitive function on the following day. CFS patients did not qualify as having affective disorder by several different diagnostic criteria. Nonetheless, CFS patients' test performances did not differ from patients with a history of major depression or dysthymia. CONCLUSIONS: It is concluded that, although CFS and major depression and dysthymia have distinct clinical features, these disorders have slowed motor and cognitive processing speed in common.

[Degradation of halothane, enflurane, and isoflurane by dry soda lime to give carbon monoxide]. / Zersetzung von Halothan, Enfluran und Isofluran an trockenem Atemkalk zu Kohlenmonoxid.

In the presence of completely dry soda lime volatile anaesthetics will decompose to carbon monoxide (CO). In an in vitro study, the absorbent (soda lime, ICI) was dried with a constant gas flow of 11/min oxygen for 120 h. The weight loss during the drying was 17.1%. Two vol% of halothane, enflurane or isoflurane in oxygen was administered with a constant flow of 0.51/min oxygen through the completely dry absorbent. Concentrations of gases were measured before and after the absorbent using mass spectrometry (MGA 1100, Perkin-Elmer) and an electrochemical NO monitor (Mini PAC CO, Dräger). The temperature inside the soda lime was monitored continuously. Shortly after adding the anaesthetic to the oxygen passing through the absorbent, carbon monoxide appeared in the outlet of the soda lime container. The measured peak concentrations varied around 450 ppm (halothane), 3500 ppm (enflurane) and 3800 ppm (isoflurane). The temperature inside the absorbent rose from the ambient temperature (19.8 degrees C) to a maximum of 52.1 degrees C during CO production and decreased when the CO production lowered after approximately 1 h (all anaesthetics). During CO production no measurable concentration of halothane left the absorber. After passing through the absorbent the concentrations of isoflurane and enflurane were slightly lower than the corresponding concentrations in the fresh gas measured before absorption.

An assessment of cognitive function and mood in chronic fatigue syndrome.

Data were gathered regarding the associates of chronic fatigue syndrome (CFS) with: (1) speed of cognitive processing, (2) motor speed, (3) ability to sustain attention, and (4) mood. Patients were given a brief neuropsychological test battery before and after double-blind treatment with terfenadine or placebo and completed a daily mood rating scale (Positive and Negative Affect Schedule) during the study. CFS patients exhibited slower cognitive processing and motor speed and lower positive affect, as compared to data reported from previous studies of healthy subjects and other patient groups; however, CFS patients did not exhibit deficits in sustained attention in comparison to other groups. The CFS patients' ability to attend to verbal versus figural stimuli and mood ratings were different from those reported in studies of patients with depression. Because of methodological limitations, these findings are preliminary, but they encourage further assessment of cognitive dysfunction and mood in CFS.

Psychiatric diagnosis and the surgical outcome of pancreas transplantation in patients with type I diabetes mellitus.

To examine the role of psychiatric diagnosis in the surgical outcome of pancreas transplantation, we studied candidates with type I diabetes mellitus. Eighty of 140 candidates underwent transplantation. Survival analysis found the extent of human leukocyte antigen-DR (HLA-DR) matching, two diagnoses, and patients' perceived support from first-degree relatives to be related to duration of full-graft function. Lifetime diagnoses of tobacco use disorder (P = 0.029) and alcohol abuse/dependence (P = 0.006) were associated with less favorable outcomes; perceived support was associated with positive outcomes (P = 0.048). Subsequent analysis suggested that the four variables independently and directly affect outcome.

Physical dependence on nicotine gum: effect of duration of use.

This study examined whether longer duration on nicotine gum promoted dependence on nicotine gum. Subjects (N = 128) answering an advertisement for smoking cessation research and wanting to quit smoking cigarettes were randomly assigned to 1- or 3-month duration of nicotine gum use. Assessments were made weekly for smoking status (with biochemical verification) and withdrawal symptoms during and at the end of treatment. Follow-up was conducted at 1, 6 and 12 months to provide exploratory data on treatment outcome. The results showed minimal nicotine gum withdrawal symptoms after gum cessation with virtually no difference in gum withdrawal between the 1- and 3-month groups. Withdrawal symptoms from the nicotine gum included difficulty with concentration, increased variability on a reaction time task, and decreased vigor. The results also showed that continuous use of the gum at 1 year was observed in 1.5% of subjects and estimated to be as high as 14%. Finally, the 3-month group experienced a 2-fold increase in abstinence compared to the 1-month group, although this difference was not statistically significant. We conclude that there is minimal physical dependence on nicotine gum.

Smokeless tobacco abstinence effects and nicotine gum dose.

There were two experiments on abstinence from smokeless tobacco. The purpose of the first experiment was to determine abstinence effects from smokeless tobacco. The purpose of the second experiment was to examine the effects of different doses of nicotine gum on smokeless tobacco abstinence effects. The subjects were male Copenhagen smokeless tobacco users who underwent 3 days of baseline measurement while continuing to use smokeless tobacco ad libitum, and 5 days of the experimental condition. In the first experiment, the subjects were assigned randomly to one of two groups and compared: continuous smokeless tobacco users (n = 10), and deprivation plus no nicotine gum (n = 10). In the second experiment, subjects were assigned randomly and in a double-blind fashion to one of three groups and compared: (1) deprivation plus 0 mg nicotine gum (n = 20); (2) deprivation plus 2 mg nicotine gum (n = 20); and (3) deprivation plus 4 mg nicotine gum (n = 20). The first experiment showed significant increases upon abstinence for the following variables: (1) craving; (2) difficulty concentrating; (3) restlessness; (4) excessive hunger; (5) eating; (6) reaction time; (7) variability of reaction time and (8) total withdrawal scores for both the self-rated and the observer-rated forms. The second experiment showed that nicotine gum failed to significantly reduce smokeless tobacco abstinence effects, although those with high cotinine levels may receive some benefit from nicotine gum.

A placebo-controlled, double-blind crossover study of fluoxetine in trichotillomania.

OBJECTIVE: It has been proposed by some investigators that trichotillomania, a disorder of chronic hair pulling, is a variant of obsessive-compulsive disorder, and some studies have suggested that the antiobessional agents clomipramine and fluoxetine are useful in treating this disorder. The authors investigated the efficacy of fluoxetine in the treatment of trichotillomania. METHOD: Twenty-one adult chronic hair pullers were recruited into an 18-week placebo-controlled, double-blind crossover study of fluoxetine, in doses up to 80 mg/day. The fluoxetine and placebo treatment phases consisted of 6-week trials of each agent separated by a 5-week washout period. Fifteen subjects (14 female and one male) completed the study; an additional female subject dropped out at 16 weeks after developing a drug reaction. RESULTS: No significant Drug by Period interactions were found in weekly subject ratings of hair pulling, weekly subject ratings of the urge to pull hair, weekly assessments of the number of hair-pulling episodes, or the estimated amount of hair pulled per week. CONCLUSIONS: The short-term efficacy of fluoxetine in the treatment of trichotillomania was not demonstrated in this study.

Situational factors and patterns associated with smokeless tobacco use.

Situational factors and topographic features associated with smokeless tobacco use were examined. Male smokeless tobacco users (N = 30) were asked to record the time, activity, and internal states associated with each dip of tobacco use over the course of 10 days. Additionally, these subjects were asked to record the activity and internal state they were experiencing every hour for a 15-hr waking period to obtain baseline rates of these events. Serum and saliva samples were obtained to measure cotinine concentrations. The activities significantly associated with smokeless tobacco use included after a meal, while driving, and while watching television. The internal states associated with smokeless tobacco use were feeling relaxed and depressed. Factor analysis of the events showed factors which are different from those found among cigarette smokers. Examination of the topographic measures of smokeless tobacco use showed that the total dip duration per day was 283.5 min, with a range of 79.7-757.1 min. This measure, along with duration of dipping time (time from onset to offset of smokeless tobacco use during the day), may be the best predictors of nicotine exposure.

Lifetime prevalence of psychiatric disorders in patients with alopecia areata.

Thirty-one patients with alopecia areata were administered a structured psychiatric interview (the Diagnostic Interview Schedule; DIS). Overall, 74% had one or more lifetime psychiatric diagnoses. Particularly noteworthy were the high lifetime prevalence rates of major depression (39%) and generalized anxiety disorder (39%). In addition, patients reported increased rates of psychiatric disorders in first-degree relatives: anxiety disorders (58%), affective disorders (35%), and substance use disorders (35%). Patients with patchy alopecia areata were more likely to have a diagnosis of generalized anxiety disorder. No relationships were found between major depression and any variable characterizing alopecia areata history. Possible interrelationships between psychiatric disorders and alopecia areata are discussed. The study suggests that patients with alopecia areata are at increased risk for psychiatric disorders, and calls attention to the need for psychiatric assessment in this population.

Depressed mood and other variables related to bone marrow transplantation survival in acute leukemia.

Routine psychiatric evaluations of 100 adult patients undergoing allogeneic bone marrow transplantation for acute leukemia were reviewed to examine the possible relationship of psychiatric and psychosocial factors to duration of survival following the procedure. Three variables were found to independently affect outcome: illness status (first remission vs. other status), presence of depressed mood, and the extent of perceived social support. Patients transplanted while in their first remission had significantly improved survival; patients with depressed mood, regardless of specific psychiatric diagnosis, had poorer outcomes; and patients with a high level of perceived social support had improved survival. The possible mechanisms by which these variables affect outcome are discussed.

Welfare status and psychosocial adjustment among 100 Hmong refugees.

Although the mental health of recently employed persons has been well studied, the mental health of welfare recipients is not well understood. Among our increasing refugee population, many receive welfare benefits at some point. The Hmong are among those who are highly represented among welfare recipients in several areas of the United States. Do psychiatrists have anything to contribute toward the resolution of high welfare rates? This question is especially relevant in refugee populations who are at increased risk for several psychiatric disorders, including depression, paranoia, and adjustment disorders. This study was undertaken among 100 Hmong refugees who had been in the United States for 8 years. Indices of mental health included two rating scales (the Zung Depression Scale and the SCL-90), five-axis DSM-III diagnoses, Hamilton Anxiety and Depression Scales, Global Assessment Scale, Brief Psychiatric Rating Scale, Inpatient Multidimensional Scale, and Mini-Mental State Exam. These indices were compared with current welfare status and the duration of time on welfare. Other comparisons with welfare included demographic characteristics, material possessions, acculturation characteristics, health and social problems, and nonoccupation avocations. Results indicate that welfare recipients show lower acculturation and elevated psychiatric symptom levels. Suggestions for ameliorating this situation are extrapolated from studies in the literature on chronically unemployed persons.

Adjustment disorders in medically ill inpatients referred for consultation in a university hospital.

The study examined medical records of 121 medical-surgical inpatients diagnosed with adjustment disorder by psychiatric consultants in a university hospital. Medical illness was the primary stressor, evoking the maladaptive reaction in 83 (68.6%) cases. These patients were largely free of preceding psychiatric problems, suffering protracted hospitalizations for advanced illnesses, particularly malignancy and diabetes; in contrast, the 38 (31.4%) patients whose adjustment disorder was precipitated by a stressor other than medical illness had established psychiatric histories and recurrent problems with relationships or finances. The data suggest that in the medically ill, identifying the primary stressor producing an adjustment disorder is more instructive than focusing upon "predominant" symptomatology and "subtypes."

Psychosocial adjustment of Hmong refugees during their first decade in the United States. A longitudinal study.

Over their first decade in the United States, 100 Hmong refugees were studied on three occasions. Data included demographic characteristics, acculturation skills, traditional affiliations and pastimes, material acquisitions, psychosocial problems, and self-rating scales. In addition to a description of the data changes, a multiple regression analysis was performed. Changes demonstrated considerable evidence of acculturation, psychiatric care seeking, and greatly reduced symptom levels for several symptom complexes. However, a large minority of subjects remain illiterate, unable to speak English, generally involved with other Hmong but not with the majority society, and/or have high symptom levels on self-rating scales. Regarding symptom changes, depression, somatization, phobia, and self-esteem symptoms improved the most with time and acculturation. On the contrary, anxiety, hostility, and paranoid symptoms changed little. Multiple regression analyses indicated that strong traditional ties (e.g., large household size, being an herbal healer), older age, marital problems, and medical complaints were most associated with high symptom levels.

Somatization among refugees: an epidemiologic study.

Somatization has been widely reported among refugee psychiatric patients since World War II, and some psychological theorists have viewed somatization as an alternative to depression. These and other theories were tested in a population survey of 97 Hmong refugees who had lived in the U.S. for several years. Four different measures of somatization were employed, including a 12-item self-rating scale, a single-item global rating based on the total interview, and somatic subscales of the two Hamilton interview-rating scales. These data demonstrate that somatization accompanies certain demographic characteristics that are associated with failure to acculturate. Somatization in this non-patient, refugee population was associated with treatment seeking and self-identified "medical problems" and with psychiatric symptoms and disorders, but not with objective evidence of medical disorder.
