ABSTRACT: The symptomatic effects of drug abuse are a result of alterations in the functioning of the following neurotransmitters or their receptors: acetylcholine, dopamine, gamma-aminobutyric acid, norepinephrine, opioids and serotonin. Anticholinergic drugs antagonize acetylcholine receptors. Dissociative drugs affect all transmitter sites. Opiates act on both opioid and adrenergic receptor sites. Psychedelic drugs stimulate serotonin release, and sedative-hypnotic drugs potentiate the gamma-aminobutyric acid receptor. Specific signs and symptoms are associated with the neurotransmitters and receptors affected by each drug class. By recognizing symptomatic changes related to particular neurotransmitters and their receptors, family physicians can accurately determine the drug class and intervene appropriately to counteract drug-induced effects.
ACOG Addresses Psychosocial Screening in Pregnant Women - Practice Guidelines
ABSTRACT: School-aged children (kindergarten through early adolescence) are establishing patterns of behavior that may last a lifetime; therefore, it is important to counsel these patients about healthy lifestyle practices during well-child examinations. Children and families should be advised to eat a diet high in fruits, vegetables, whole grains, low-fat or nonfat dairy products, beans, fish, and lean meats, while limiting sugar, fast food, and highly processed foods. Children should engage in at least 60 minutes per day of moderate to vigorous physical activity, and screen time (e.g., television, computer, video games) should be limited to no more than one to two hours of quality programming daily. Most school-aged children require 11 hours of sleep per night. Decreased sleep is associated with behavioral issues, decreased concentration at school, and obesity. Children should brush their teeth twice per day with a toothpaste containing fluoride. Unintentional injury is the leading cause of death in this age group in the United States, and families should be counseled on traffic, water, sports, and firearm safety. Because high-risk behaviors may start in early adolescence, many experts recommend screening for tobacco, alcohol, and drug use beginning at 11 years of age. Sexually active adolescents should be counseled on protecting against sexually transmitted infections, and should be screened for these infections if indicated.
ABSTRACT: Serious health problems, risky behavior, and poor health habits persist among adolescents despite access to medical care. Most adolescents do not seek advice about preventing leading causes of morbidity and mortality in their age group, and physicians often do not find ways to provide it. Although helping adolescents prevent unintended pregnancy, sexually transmitted infections, unintentional injuries, depression, suicide, and other problems is a community-wide effort, primary care physicians are well situated to discuss risks and offer interventions. Evidence supports routinely screening for obesity and depression, offering testing for human immunodeficiency virus infection, and screening for other sexually transmitted infections in some adolescents. Evidence validating the effectiveness of physician counseling about unintended pregnancy, gang violence, and substance abuse is scant. However, physicians should use empathic, personal messages to communicate with adolescents about these issues until studies prove the benefits of more specific methods. Effective communication with adolescents requires seeing the patient alone, tailoring the discussion to the individual patient, and understanding the role of the parents and of confidentiality.
ABSTRACT: Substance misuse is common among patients in primary care settings. Although it has a substantial health impact, physicians report low levels of preparedness to identify and assist patients with substance use disorders. An effective approach to office-based treatment includes a coherent framework for identifying and managing substance use disorders and specific strategies to promote behavior change. Brief validated screening tools allow rapid and efficient identification of problematic drug use, including prescription medication misuse. After a positive screening, a brief assessment should be performed to stratify patients into three categories: hazardous use, substance abuse, or substance dependence. Patients with hazardous use benefit from brief counseling by a physician. For patients with substance abuse, brief counseling is also indicated, with the addition of more intensive ongoing follow-up and reevaluation. In patients with substance dependence, best practices include a combination of counseling, referral to specialty treatment, and pharmacotherapy (e.g., drug tapering, naltrexone, buprenorphine, methadone). Comorbid mental illness and intimate partner violence are common in patients with substance use disorders. The use of a motivational rather than a confrontational communication style during screening, counseling, and treatment is important to improve patient outcomes.
