Tourette's Syndrome - Article
ABSTRACT: Tourette's syndrome is a movement disorder most commonly seen in school-age children. The incidence peaks around preadolescence with one half of cases resolving in early adulthood. Tourette's syndrome is the most common cause of tics, which are involuntary or semivoluntary, sudden, brief, intermittent, repetitive movements (motor tics) or sounds (phonic tics). It is often associated with psychiatric comorbidities, mainly attention-deficit/hyperactivity disorder and obsessive-compulsive disorder. Given its diverse presentation, Tourette's syndrome can mimic many hyperkinetic disorders, making the diagnosis challenging at times. The etiology of this syndrome is thought to be related to basal ganglia dysfunction. Treatment can be behavioral, pharmacologic, or surgical, and is dictated by the most incapacitating symptoms. Alpha2-adrenergic agonists are the first line of pharmacologic therapy, but dopamine-receptor-blocking drugs are required for multiple, complex tics. Dopamine-receptor-blocking drugs are associated with potential side effects including sedation, weight gain, acute dystonic reactions, and tardive dyskinesia. Appropriate diagnosis and treatment can substantially improve quality of life and psychosocial functioning in affected children.
Oppositional Defiant Disorder - Article
ABSTRACT: Oppositional defiant disorder is defined by the Diagnostic and Statistical Manual of Mental Disorders, 4th ed., as a recurrent pattern of developmentally inappropriate, negativistic, defiant, and disobedient behavior toward authority figures. This behavior often appears in the preschool years, but initially it can be difficult to distinguish from developmentally appropriate, albeit troublesome, behavior. Children who develop a stable pattern of oppositional behavior during their preschool years are likely to go on to have oppositional defiant disorder during their elementary school years. Children with oppositional defiant disorder have substantially strained relationships with their parents, teachers, and peers, and have high rates of coexisting conditions such as attention-deficit/hyperactivity disorder and mood disorders. Children with oppositional defiant disorder are at greater risk of developing conduct disorder and antisocial personality disorder during adulthood. Psychological intervention with both parents and child can substantially improve short- and long-term outcomes. Research supports the effectiveness of parent training and collaborative problem solving. Collaborative problem solving is a psychological intervention that aims to develop a child's skills in tolerating frustration, being flexible, and avoiding emotional overreaction. When oppositional defiant disorder coexists with attention-deficit/hyperactivity disorder, stimulant therapy can reduce the symptoms of both disorders.
Fatigue: An Overview - Article
ABSTRACT: Fatigue, a common presenting symptom in primary care, negatively impacts work performance, family life, and social relationships. The differential diagnosis of fatigue includes lifestyle issues, physical conditions, mental disorders, and treatment side effects. Fatigue can be classified as secondary to other medical conditions, physiologic, or chronic. The history and physical examination should focus on identifying common secondary causes (e.g., medications, anemia, pregnancy) and life-threatening problems, such as cancer. Results of laboratory studies affect management in only 5 percent of patients, and if initial results are normal, repeat testing is generally not indicated. Treatment of all types of fatigue should include a structured plan for regular physical activity that consists of stretching and aerobic exercise, such as walking. Caffeine and modafinil may be useful for episodic situations requiring alertness. Short naps are proven performance enhancers. Selective serotonin reuptake inhibitors, such as fluoxetine, paroxetine, or sertraline, may improve energy in patients with depression. Patients with chronic fatigue may respond to cognitive behavior therapy. Scheduling regular follow-up visits, rather than sporadic urgent appointments, is recommended for effective long-term management.
ABSTRACT: Delirium is common in hospitalized older patients and may be a symptom of a medical emergency, such as hypoxia or hypoglycemia. It is characterized by an acute change in cognition and attention, although the symptoms may be subtle and usually fluctuate throughout the day. This heterogeneous syndrome requires prompt recognition and evaluation, because the underlying medical condition may be life threatening. Risk factors for delirium include visual impairment, previous cognitive impairment, severe illness, and an elevated blood urea nitrogen/serum creatinine ratio. Interventions that have been shown to reduce the incidence of delirium in at-risk hospitalized patients include repeated reorientation of the patient to person and place, promotion of good sleep hygiene, early mobilization, correction of dehydration, and the minimization of unnecessary noise and stimuli. The treatment of delirium centers on the identification and management of the medical condition that triggered the delirious state. Nonpharmacologic interventions may be beneficial, but antipsychotic agents may be needed when the cause is nonspecific and other interventions do not sufficiently control symptoms such as severe agitation or psychosis. Although delirium is a temporary condition, it may persist for several months in the most vulnerable patients. Patient outcomes at one year include a higher mortality rate and a lower level of functioning compared with age-matched control patients.
Effectiveness of Brief Alcohol Interventions in Primary Care - Cochrane for Clinicians
ABSTRACT: Symptoms of childhood attention-deficit/hyperactivity disorder affect cognitive, academic, behavioral, emotional, social, and developmental functioning. Attention-deficit/hyperactivity disorder is the most commonly diagnosed neurodevelopmental disorder in children and adolescents. An estimated 2 to 16 percent of school-aged children have been diagnosed with the disorder. The prevalence of attention-deficit/hyperactivity disorder in the primary care setting is similar to that in the general community, depending on the diagnostic criteria and population studied. The causality of attention-deficit/hyperactivity disorder is relatively unknown. Most recent studies focus on the role of dopamine; norepinephrine; and, most recently, serotonin neurotransmitters. The disorder is classified into three general subtypes: predominantly hyperactive-impulsive, predominantly inattentive, and combined. Screening tools and rating scales have been devised to assist with the diagnosis. Appropriate treatment can dramatically improve the function and quality of life of the patient and family. Pharmacologic treatment includes stimulants, such as methylphenidate and mixed amphetamine salts, or nonstimulants, such as atomoxetine. Behavioral approaches, particularly those that reward desirable behavior, are also effective. A combination of pharmacologic and behavioral therapies is recommended.
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.
Evaluation and Treatment of Enuresis - Article
ABSTRACT: Enuresis is defined as repeated, spontaneous voiding of urine during sleep in a child five years or older. It affects 5 to 7 million children in the United States. Primary nocturnal enuresis is caused by a disparity between bladder capacity and nocturnal urine production and failure of the child to awaken in response to a full bladder. Less commonly, enuresis is secondary to a medical, psychological, or behavioral problem. A diagnosis usually can be made with a history focusing on enuresis and a physical examination followed by urinalysis. Imaging and urodynamic studies generally are not needed unless specifically indicated (e.g., to exclude suspected neurologic or urologic disease). Primary nocturnal enuresis almost always resolves spontaneously over time. Treatment should be delayed until the child is able and willing to adhere to the treatment program; medications are rarely indicated in children younger than seven years. If the condition is not distressing to the child, treatment is not needed. However, parents should be reassured about their child's physical and emotional health and counseled about eliminating guilt, shame, and punishment. Enuresis alarms are effective in children with primary nocturnal enuresis and should be considered for older, motivated children from cooperative families when behavioral measures are unsuccessful. Desmopressin is most effective in children with nocturnal polyuria and normal bladder capacity. Patients respond to desmopressin more quickly than to alarm systems. Combined treatment is effective for resistant cases.
