ABSTRACT: Obesity is a complex, multifactorial condition in which excess body fat may put a person at health risk. National data indicate that the prevalence of obesity in the United States is increasing in children and adults. Reversing these trends requires changes in individual behavior and the elimination of societal barriers to healthy lifestyle choices. Basic treatment of overweight and obese patients requires a comprehensive approach involving diet and nutrition, regular physical activity, and behavioral change, with an emphasis on long-term weight management rather than short-term extreme weight reduction. Physicians and other health professionals have an important role in promoting preventive measures and encouraging positive lifestyle behaviors, as well as identifying and treating obesity-related comorbidities. Health professionals also have a role in counseling patients about safe and effective weight loss and weight maintenance programs. Recent evidence-based guidelines from the National Heart, Lung, and Blood Institute, as well as recommendations from the American Academy of Pediatrics, American Association of Clinical Endocrinologists/American College of Endocrinology, American Obesity Association, U.S. Clinical Preventive Services Task Force, Institute of Medicine, and World Health Organization can be consulted for information and guidance on the identification and management of overweight and obese patients.
Evaluation and Treatment of ADHD - Article
ABSTRACT: Symptoms of attention-deficit/hyperactivity disorder (ADHD) are present in as many as 9 percent of school-age children. ADHD-specific questionnaires can help determine whether children meet diagnostic criteria for the disorder. The recommended evaluation also includes documenting the type and severity of ADHD symptoms, verifying the presence of normal vision and hearing, screening for comorbid psychologic conditions, reviewing the child's developmental history and school performance, and applying objective measures of cognitive function. The stimulants methylphenidate and dextroamphetamine remain the pharmacologic agents of first choice for the management of ADHD. These agents are equally effective in improving the core symptoms of the disorder, but individual children may respond better to one stimulant medication than to another. Achievement of maximal benefit may require titration of the initial dosage and dosing before breakfast, before lunch and in the afternoon. The family physician should tailor the treatment plan to meet the unique needs of the child and family. Psychosocial, behavioral and educational strategies that enhance specific behaviors may improve educational and social functioning in the child with ADHD.
ABSTRACT: Attention-deficit/hyperactivity disorder (ADHD) is the most common psychiatric disorder of childhood and often persists into adulthood. ADHD is a neurophysiologic disorder defined in behavioral terms and associated with significant morbidity in the realms of social and academic success, and self-esteem. ADHD is often associated with comorbid psychiatric disorders and learning disabilities, which further impede the successful development of these persons. It is essential that family physicians be knowledgeable about the presentation and diagnosis of ADHD. Stimulant medications continue to be the mainstay of treatment, although many other medications (such as antidepressants and alpha blockers) are helpful adjuvants to therapy. Current recommendations for treatment include an individualized, multimodal approach involving parents, teachers, counselors and the school system. Treatment follow-up includes monitoring response to medications in various settings, as well as side effects. With time and interest, the family physician can develop the skills needed to treat this disorder.
Headaches in Children and Adolescents - Article
ABSTRACT: Headaches are common during childhood and become more common and increase in frequency during adolescence. The rational, cost-effective evaluation of children with headache begins with a careful history. The first step is to identify the temporal pattern of the headache--acute, acute-recurrent, chronic-progressive, chronic-nonprogressive, or mixed. The next step is a physical and neurologic examination focusing on the optic disc, eye movements, motor asymmetry, coordination, and reflexes. Neuroimaging is not routinely warranted in the evaluation of childhood headache and should be reserved for use in children with chronic-progressive patterns or abnormalities on neurologic examination. Once the headache diagnosis is established, management must be based on the frequency and severity of headache and the impact on the patient's lifestyle. Treatment of childhood migraine includes the intermittent use of oral analgesics and antiemetics and, occasionally, daily prophylactic agents. Often, the most important therapeutic intervention is confident reassurance about the absence of serious underlying neurologic disease.
ABSTRACT: Family physicians should take advantage of each contact with smokers to encourage and support smoking cessation. Once a patient is identified as a smoker, tools are available to assess readiness for change. Using motivational interviewing techniques, the physician can help the patient move from the precontemplation stage through the contemplation stage to the preparation stage, where plans are made for the initiation of nicotine replacement and/or bupropion therapy when indicated. Continued motivational techniques and support are needed in the action stage, when the patient stops smoking. Group or individual behavioral counseling can facilitate smoking cessation and improve quit rates. Combined use of behavioral and drug therapies can dramatically improve the patient's chance of quitting smoking. A plan should be in place for recycling the patient through the appropriate stages if relapse should occur.
Autism: A Medical Primer - Article
ABSTRACT: Autistic disorder, a pervasive developmental disorder resulting in social, language, or sensorimotor deficits, occurs in approximately seven of 10,000 persons. Early detection and intervention significantly improve outcome, with about one third of autistic persons achieving some degree of independent living. Indications for developmental evaluation include no babbling, pointing, or use of other gestures by 12 months of age, no single words by 16 months of age, no two-word spontaneous phrases by 24 months of age, and loss of previously learned language or social skills at any age. The differential diagnosis includes other psychiatric and pervasive developmental disorders, deafness, and profound hearing loss. Autism is frequently associated with fragile X syndrome and tuberous sclerosis, and may be caused by lead poisoning and metabolic disorders. Common comorbidities include mental retardation, seizure disorder, and psychiatric disorders such as depression and anxiety. Behavior modification programs are helpful and are usually administered by multidisciplinary teams, targeted medication is used to address behavior concerns. Many different treatment approaches can be used, some of which are unproven and have little scientific support. Parents may be encouraged to investigate national resources and local support networks.
Nocturnal Enuresis - Article
ABSTRACT: Nocturnal enuresis is a common problem that can be troubling for children and their families. Recent studies indicate that nocturnal enuresis is best regarded as a group of conditions with different etiologies. A genetic component is likely in many affected children. Research also indicates the possibility of two subtypes of patients with nocturnal enuresis: those with a functional bladder disorder and those with a maturational delay in nocturnal arginine vasopressin secretion. The evaluation of nocturnal enuresis requires a thorough history, a complete physical examination, and urinalysis. Treatment options include nonpharmacologic and pharmacologic measures. Continence training should be incorporated into the treatment regimen. Use of a bed-wetting alarm has the highest cure rate and the lowest relapse rate; however, some families may have difficulty with this treatment approach. Desmopressin and imipramine are the primary medications used to treat nocturnal enuresis, but both are associated with relatively high relapse rates.
ABSTRACT: Overweight in childhood and adolescence is an important public health issue because of its rapidly increasing prevalence and associated adverse medical and social consequences. Recent studies have estimated that 15 percent of children in the United States are at risk for overweight, and an additional 15 percent are overweight. Important predictors of overweight include age, sex, race/ethnicity, and parental weight status. Generally, school-based prevention programs are not successful in reducing the prevalence of obesity. Treatment interventions include behavioral therapy, reduction in sedentary behavior, and nutrition and physical activity education. These interventions are moderately successful but may not be generalized to the primary care setting. Family physicians should focus on identifying at-risk and overweight children and adolescents at an early stage and educating families about the health consequences of being overweight. Interventions should be tailored to the patient and involve the entire family.
ABSTRACT: Psychosis may pose a greater challenge than cognitive decline for patients with dementia and their caregivers. The nature and frequency of psychotic symptoms varies over the course of illness, but in most patients, these symptoms occur more often in the later stages of disease. Management of psychosis requires a comprehensive nonpharmacologic and pharmacologic approach, including an accurate assessment of symptoms, awareness of the environment in which they occur, and identification of precipitants and how they affect patients and their caregivers. Nonpharmacologic interventions include counseling the caregiver about the nonintentional nature of the psychotic features and offering coping strategies. Approaches for the patient involve behavior modification; appropriate use of sensory intervention; environmental safety; and maintenance of routines such as providing meals, exercise, and sleep on a consistent basis. Pharmacologic treatments should be governed by a "start low, go slow" philosophy; a monosequential approach is recommended, in which a single agent is titrated until the targeted behavior is reduced, side effects become intolerable, or the maximal dosage is achieved. Atypical antipsychotics have the greatest effectiveness and are best tolerated. Second-line medications include typical antipsychotics for short-term therapy; and, less often, anticonvulsants, acetylcholinesterase inhibitors, antidepressants, and anxiolytics. Goals of treatment should include symptom reduction and preservation of quality of life.
ABSTRACT: In response to the growing population of older patients with incontinence, pharmaceutical companies are developing new drugs to treat the condition. Before prescribing medications for incontinence, however, physicians should determine the nature and cause of the patient's incontinence. The evaluation should rule out reversible conditions, conditions requiring special evaluation, and overflow bladder. The best treatment for urge incontinence is behavior therapy in the form of pelvic floor muscle exercises. Medications, used as an adjunct to behavior therapy, can provide additional benefit. Many therapies are available for patients with stress incontinence, including pelvic floor muscle exercise, surgery, intravaginal support devices, pessaries, peri-urethral injections, magnetic chairs, and intraurethral inserts. No medication has been approved for the treatment of stress incontinence, although medications are under development.
