Protopathic stimulant use among children with symptoms of ADHD

The purpose of the current study was to examine protopathic stimulant use among children with the symptoms of ADHD but do not have a diagnosis of ADHD. Protopathic or prodromal stimulant use refers to the use of stimulants by children with the symptoms of ADHD prior to a diagnosis of ADHD. In the current study, we examined children with the symptoms of ADHD who received stimulant treatment across time and with respect to several background variables. Our results indicate that these children who receive stimulant treatment without a diagnosis of ADHD are significantly more like to be eventually diagnosed with ADHD than not. Results also indicate that these children who receive stimulant treatment but do not yet have a diagnosis of ADHD are significantly more likely to have insurance that does not pay for diagnostic procedures. These results are discussed in view of treatment.     

Early detection of depression by primary care physicians.

The overall prevalence of depression is from 3.5% to 27%. The burden of suffering is high and includes death through suicide. In most cases treatment is effective, but important episodes of depression are being missed. To determine whether a brief, systematic assessment for the early detection of depression should be part of the periodic health examination we searched MEDLINE and the Science Citation Index for randomized controlled trials that evaluated the effectiveness of early detection of depression with a questionnaire. Seven instruments met our quality criteria; the Beck Depression Inventory, the Center for Epidemiologic Studies Depression Scale, the Zung Self-Assessment Depression Scale, the General Health Questionnaire, the Hopkins Symptom Checklist, the Mental Health Inventory and the Hospital Anxiety and Depression Scale. The four randomized controlled trials failed to provide adequate evidence of the benefit of routine screening. Early detection is difficult because of depression''s natural history, the role of symptoms, the cultural diversity of Canada and how detection instruments have been developed. Depression deserves careful attention from primary care physicians; however, further research and development is required before the widespread routine use of any detection test can be recommended.     

Invited Review Anticholinesterases: dramatic aspects of their use and misuse

While the lore of anticholinesterases (antiChEs), particularly physostigmine and its natural source, the Calabar bean, is a subject of ethnomedicine and predates our scientific era, the pharmacological development of physostigmine analogues and related agents and of the antiChEs of the organophosphorus (OP) type, is a matter of the last two centuries; this development has reached an exponential character in the last fifty years.This explosion relates to certain uses and misuses of these drugs and this aspect of antiChEs is the main focus of this article. Firstly, there is the matter of Senile Dementia of Alzheime’s Type (SDAT); while there are several clinical applications of antiChEs, their employment in the treatment of SDAT is the last and most intense foray in their medical history and this article will focus on the uses and misuses of antiChEs in this area[ Secondly, the applied use of antiChEs as insecticides which coincided with the historical development of OP antiChEs was and is, of major significance for the agricultural economy of both advanced and underdeveloped countries, as this employment may mean the difference between life and starvation. However, there are notable dangers with this application of OP drugs, as will be emphasized in this article. Thirdly, there is the significant and tragic development of the OP drugs as warfare agents and tools for terrorists and rogue states and this article will discuss the several types of toxicity of OP agents and their mechanisms, the enigma of the Persian Gulf War Syndrome being particularly stressed. Altogether, the immense range of antiChE topics includes areas of great basic interest and of practical applications that are of significant benefit to mankind as well as of potential danger. © 1998 Elsevier Science Ltd.

Quality and safety of medication use in primary care: consensus validation of a new set of explicit medication assessment criteria and prioritisation of topics for improvement

Background  

Addressing the problem of preventable drug related morbidity (PDRM) in primary care is a challenge for health care systems internationally. The increasing implementation of clinical information systems in the UK and internationally provide new opportunities to systematically identify patients at risk of PDRM for targeted medication review. The objectives of this study were (1) to develop a set of explicit medication assessment criteria to identify patients with sub-optimally effective or high-risk medication use from electronic medical records and (2) to identify medication use topics that are perceived by UK primary care clinicians to be priorities for quality and safety improvement initiatives.     

Facilitating care of patients with HIV infection by hospital and primary care teams.

To complement the role of primary care teams working with patients with HIV disease and AIDS within greater London and to ease the load on the special hospital units a home support team was developed. It comprises six specialist nurses, a general practitioner trained medical officer, and a receptionist and is funded from regional and district sources and charities. A nurse is available for out of hours and emergency weekend calls, with support from the patient''s general practitioner or the attached medical officer. During the first 18 months 249 patients were seen; the mean duration of care was five months. Nearly a third (18/50, 30%) of patients who were terminally ill died at home. The team''s activities included practical nursing care, emotional support for carers and patients, and advice and guidance to primary care teams. Problems in providing care in patients'' homes included issues relating to confidentiality and 24 hour cover. With the increasing incidence of HIV infection the home support team may be a useful model for care of large numbers of patients with symptomatic HIV disease, especially in large urban areas.     

When is a patient's use of primary care services unwarranted? Some answers from physicians.

To explore physicians'' perceptions of what constitutes unwarranted use of their services, examples of patient-initiated encounters considered unwarranted were contributed by physicians and categorized as requests for unnecessary services, inappropriately timed encounters or inconsiderate requests. A random sample of family and general practitioners in Ontario was surveyed with a questionnaire derived from these examples. Although there was no unanimity, examples of missed appointments, requests for further, unnecessary investigations, consultations or admissions to hospital, duplication of services, visits prompted by a desire to obtain free samples of over-the-counter drugs, some out-of-hours calls, and visits of healthy workers to obtain notes regarding fitness for work were seen as unwarranted by 70% or more of the respondents.     

Understanding the expanding role of primary care physicians (PCPs) to primary psychiatric care physicians (PPCPs): enhancing the assessment and treatment of psychiatric conditions

Aim In the current healthcare system primary care physicians (PCPs) have, in effect, become the primary psychiatric care physicians (PPCPs) for many of their patients. Being the PPCP in an already busy and stressful medical industry presents additional time management and treatment challenges to successfully manage patients' medical and psychiatric needs. The aim of the study was to ascertain PCPs' psychiatric assessment and treatment practices and to determine the extent to which PCPs have a need for using a structured psychiatric assessment tool.Method We sent 300 PCPs a survey to examine their psychiatric assessment and treatment practices. A one-page questionnaire was used to inquire about PCPs' psychiatric care practice habits including types of conditions treated, psychiatric medications prescribed, assessment methods used, interest in using a structured assessment tool and referral sources used. Sixty-eight usable surveys (23%) were returned.Results PCPs identify approximately one-third of their patients as mental health patients. They are treating a wide range of psychiatric conditions and prescribing a variety of psychiatric medications. The vast majority are using traditional clinical interviewing as their primary method of psychiatric assessment. However, the majority were willing to use a structured psychiatric assessment tool.Conclusion PCPs are serving a useful role in providing psychiatric treatment to many of their patients. Using a more structured psychiatric assessment method in practice could ultimately strengthen the assessment and treatment of psychiatric conditions in primary care settings.     

Placebo medication use in patient care: a survey of medical interns

The use of placebo medication, long recognized by clinicians, often has serious practical implications, such as patient deception. Past evidence has suggested that resident physicians tend to misuse placebo medication. Interns from two consecutive years of a residency program were surveyed anonymously to assess their knowledge and use of placebos. Of the 74 interns surveyed, 44 (59%) were familiar with placebo use in patient care. Fifty percent of these interns familiar with placebo use had learned about placebos from another physician. All interns who had learned about placebos during their internships had learned from another physician, whereas interns who had gained their knowledge of placebos as medical students were as likely to have learned from the medical literature as they were to have learned from a physician (P = 0.027). Interns aware of placebo use were more likely to consider placebo administration for suspected, factitious pain (P = 0.022). The present study uncovered no relationship between interns' estimations of placebo efficacy and the utility they attributed to placebos in assessing a complaint of pain. This suggests that conceptual inconsistencies underlie their use of placebos. Interns often learn of placebos as medical students and are influenced by physician-mentors. Placebo use in patient care is an area of attention for medical educators.     

Oral health behaviour and socio-demographic profile of subjects with Alzheimer's disease as reported by their family caregivers

Objective: To evaluate the oral health care provided to subjects with Alzheimer's disease (AD) as reported by their family caregivers. Method: Structured interviews were performed with 56 Alzheimer caregivers from the Group of relatives and friends of subjects with AD of the Hospital de Clínicas de Porto Alegre. Spearman and Pearson correlations were performed. Results: The mean age of the subjects with AD was 76.09 (±7.76) years, 53.6% were female and 58.9% were in the advanced stage of AD. The mean number of teeth present was 11.66 (±10.94), and oral hygiene was performed 2.21 (±1.04) times/day. The provision of oral health care to subjects with AD was carried out by caregivers in 85.7%. Oral hygiene was provided by the caregivers to the subjects with AD with the aid of a toothbrush and/or gauze embedded with non‐fluoridated mouthwash in the majority of the cases. Complete dental prostheses were cleaned with the aid of mouthwashes instead of denture brushes by 44% of the subjects/caregivers. There was a significant association between the number of teeth in the subjects with AD and the number of oral hygiene procedures performed per day and current smoking. Conclusion: Oral health care planning for subjects with AD should take into account caregivers’ perceptions and knowledge about oral health and hygiene as caregivers represent the primary providers to these patients when the disease progresses from early to more advanced stages.     

Atomoxetine Effects on Executive Function as Measured by the BRIEF-A in Young Adults with ADHD: A Randomized,Double-Blind,Placebo-Controlled Study

Objective

To evaluate the effect of atomoxetine treatment on executive functions in young adults with attention-deficit/hyperactivity disorder (ADHD).

Methods

In this Phase 4, multi-center, double-blind, placebo-controlled trial, young adults (18–30 years) with ADHD were randomized to receive atomoxetine (20–50 mg BID, N = 220) or placebo (N = 225) for 12 weeks. The Behavior Rating Inventory of Executive Function-Adult (BRIEF-A) consists of 75 self-report items within 9 nonoverlapping clinical scales measuring various aspects of executive functioning. Mean changes from baseline to 12-week endpoint on the BRIEF-A were analyzed using an ANCOVA model (terms: baseline score, treatment, and investigator).

Results

At baseline, there were no significant treatment group differences in the percentage of patients with BRIEF-A composite or index T-scores ≥60 (p>.5), with over 92% of patients having composite scores ≥60 (≥60 deemed clinically meaningful for these analyses). At endpoint, statistically significantly greater mean reductions were seen in the atomoxetine versus placebo group for the BRIEF-A Global Executive Composite (GEC), Behavioral Regulation Index (BRI), and Metacognitive Index (MI) scores, as well as the Inhibit, Self-Monitor, Working Memory, Plan/Organize and Task Monitor subscale scores (p<.05), with decreases in scores signifying improvements in executive functioning. Changes in the BRIEF-A Initiate (p = .051), Organization of Materials (p = .051), Shift (p = .090), and Emotional Control (p = .219) subscale scores were not statistically significant. In addition, the validity scales: Inconsistency (p = .644), Infrequency (p = .097), and Negativity (p = .456) were not statistically significant, showing scale validity.

Conclusion

Statistically significantly greater improvement in executive function was observed in young adults with ADHD in the atomoxetine versus placebo group as measured by changes in the BRIEF-A scales.

Vietnamese diabetic patients and their physicians: what ethnography can teach us

Objectives To describe the cultural context of type 2 diabetes mellitus among Vietnamese immigrants in the United States, including people''s ideas about cause and proper treatment; and to suggest ways in which better control of the disease can be achieved in this population. Design The method was ethnographic. A native speaker used a structured interview guide to talk with 38 Vietnamese patients, and family members of 2 other patients, being treated for type 2 diabetes. In addition, 8 Vietnamese health providers—5 physicians, 2 nurses, and an herbalist—were interviewed. Setting A low-income area of southern California populated by a large number of Vietnamese. Participants Forty patients being treated for type 2 diabetes and 8 health practitioners. Results Three quarters of the patients had not achieved good control of their diabetes. Ideas about the cause and proper treatment of the disease were culturally shaped. Many patients used eastern (herbal) medicine and described a strong aversion to insulin injections. Patients stopped taking their oral medications when using eastern medicine, and a quarter lowered their dose whenever they felt “out of balance.” Almost two thirds had used traditional home remedies for diabetes. Two had received nonstandard medical care from neighborhood physicians trained in Viet Nam; 1 of these patients died during the study. Conclusion The Vietnamese community and physicians serving that community need culturally appropriate education about type 2 diabetes and modern therapy for the disease.Close to 800,000 Vietnamese immigrants were living in the United States in 2000.¹ Nationally, mortality related to type 2 diabetes mellitus is higher for Asians and Pacific Islanders than for non-Hispanic whites,^2,3 and there is evidence that many Vietnamese are unfamiliar with the clinical manifestations of the disease. For example, a telephone survey of 426 Vietnamese in Houston, Texas, found that 60% did not recognize any signs or symptoms of diabetes when important symptoms such as increased urinary frequency were read to them.⁴For Vietnamese immigrants, lack of past contact with diabetic patients may be a factor in their unfamiliarity with the disease. Type 2 diabetes is relatively uncommon in Viet Nam, where it is called tieu duong—literally, “urinate sugar.” (In rural areas of the country, people have traditionally diagnosed it by seeing ants attracted to the urine.) In the United States, however, its prevalence is increasing in Vietnamese as in other ethnic groups, perhaps because Vietnamese immigrants have adopted a higher-calorie diet and more sedentary lifestyle that puts people at risk of developing obesity, a major risk factor for the disease. One primary care physician in San Jose, California, reported that half of his Vietnamese patients had type 2 diabetes (Dr Alfonso Bañuelos Jr, oral communication, July 2000).Our study was carried out in Orange County, California, home to the largest number of Vietnamese (nearly 140,000) outside of Viet Nam.⁵(p33) As in national data, county figures show higher diabetes-related morbidity and mortality among Asians and Pacific Islanders than among non-Hispanic whites.⁶ In July 2000, we investigated factors underlying this increased risk. Through preliminary inquiries, we had learned that knowledge of diabetes—especially early symptoms such as thirst—was minimal in the local Vietnamese community.     

The use and misuse of public information by foraging red crossbills

Group foragers may assess patch quality more efficiently bypaying attention to the sampling behavior of group members foragingin the same patch (i.e., using "public information"). To determinewhether red crossbills (Loxia curvirostra) use public informationto aid their patch departure decisions, we conducted experimentsthat compared the sampling behavior of crossbills foraging ona two-patch system (one patch was always empty, one patch containingseeds) when alone, in pairs, and in flocks of three. When foragingalone, crossbills departed from empty patches in a way thatwas qualitatively consistent with energy maximization. We foundevidence for the use of public information when crossbills werepaired with two flock mates, but not when paired with one flockmate. When foraging with two flock mates, crossbills sampledapproximately half the number of cones on the empty patch beforedeparting as compared to when solitary. Furthermore, as expected ifpublic information is used, the variance in both the numberof cones and time spent on the empty patch decreased when crossbillsforaged with two flock mates as compared to when alone. Althoughhigh frequencies of scrounging reduce the availability of publicinformation, scrounging is usually uncommon in crossbills, apparentlybecause they exploit divisible patches. Consequently, publicinformation is likely to be important to crossbills in the wild.We also show that feeding performance is greatly diminishedwhen the feeding performances of flock mates differ. This providesa mechanism that will favor assortative grouping by phenotypewhen phenotypes affect feeding performance, which may in turnpromote speciation in some groups of animals.     

Skills training groups for men with ADHD in compulsory care due to substance use disorder: a feasibility study

Dialectical behavior therapy (DBT)-based skills training has been developed and previously evaluated for adults with ADHD in a psychiatric outpatient context. The aim of the present study was to evaluate the feasibility of DBT-based skills training as a voluntary intervention for men with ADHD in compulsory care due to severe substance abuse. Forty sufficiently detoxified men with ADHD in compulsory care due to life-threatening substance use disorder (SUD) were included in DBT-based skills training groups. Self- and staff-rating scales were administered before and after the treatment. The refusal rate was 42.9 %. Of those who started the DBT-based skills training, 70 % completed the treatment (attendance at ≥75 % of the sessions). The treatment acceptability was good. Both ADHD and psychiatric symptoms decreased from pre- to post-intervention in self-ratings, but not in staff ratings. The patients reported improved general well-being. The correlation between self- and staff ratings was poor. Motivation for voluntary nonpharmacological treatment was low in a compulsory care context. However, the results indicate that a DBT-based skills training program for adults with ADHD may be feasible for some patients with ADHD in combination with SUD in compulsory care, provided that considerable resources are allocated with adjustments to the target group and compulsory care context.     

Palliative care: views of patients and their families.

OBJECTIVE--To investigate the current problems and needs of terminally ill cancer patients and their family members, and to discover their views of hospital, community, and support team services. DESIGN--Prospective study of patients and families by questionnaire interviews in the patients'' homes. SETTING--Inner London and north Kent (London suburbs). SUBJECTS--65 Patients, each with a member of their family or a career. MAIN OUTCOME MEASURES--Ratings of eight current problems and ratings and comments on three services-hospital doctors and nurses, general practitioners and district nurses, and the support team staff-obtained after a minimum of two weeks'' care from palliative care support teams. RESULTS--Effect of anxiety on the patient''s nearest career. and symptom control were rated as the most severe current problems by both patients and families; a few patients and families identified other severe problems. Families'' ratings of pain control, symptom control, and effect of anxiety on the patient were significantly worse than the patients'' ratings (p less than 0.05). Support teams received the most praise, being rated by 58 (89%) patients and 59 (91%) of family members as good as excellent. General practitioners and district nurses were rated good or excellent by 46 (71%) patients and 46 (71%) family members, but six (9%) in each group rated the service as poor or very bad, and ratings in the inner London district were significantly worse than those in the outer London district. Hospital doctors and nurses were rated good or excellent by 22 (34%) patients and 35 (54%) of family members, and 14 (22%) patients and 15 (23%) family members rated this service as poor or very bad. Negative comments referred to communication (especially at diagnosis), coordination of services, the attitude of the doctor, delays in diagnosis, and difficulties in getting doctors to visit at home. Family members were more satisfied with the services than were patients. CONCLUSIONS--Palliative care needs to include both the patient and family because the needs of the family may exceed those of the patient. Support teams and some hospital and community doctors and nurses met the perceived needs of dying patients and families, but better education and organisation of services are needed.
