Drug addiction is a complex condition characterized by intense and, at times, uncontrollable drug craving, along with the desire to compulsively seek and use drugs that persists even in the face of devastating consequences. While the path to drug addiction begins with the voluntary act of taking drugs, over time, the ability of a person to choose not to do so becomes compromised and seeking and consuming the drug becomes compulsive. This behavior results largely from the effects of prolonged drug exposure on brain functioning. Addiction is a brain disease that affects multiple brain circuits, including those involved in reward and motivation, learning and memory and inhibitory control over behavior. Some individuals are more susceptible to becoming an addict, depending on genetic makeup, age of exposure to drugs, other environmental influences and the interplay of all these factors. Addiction is often more than just compulsive drug consumption and can have far reaching consequences. For example, drug abuse and addiction increase the risk of a person to have a variety of other mental and physical illnesses related to a drug abuse. People may suffer the toxic effects of the drugs themselves. Additionally, a wide range of dysfunctional behaviors may result from drug abuse and interfere with normal functioning within a family, the workplace and the community. Because drug abuse and addiction have so many dimensions and disrupt so many aspects of the life of an individual, treatment is not simple. Effective treatment programs typically incorporate many components, each directed to a particular aspect of the illness and its consequences. Addiction treatment must help the individual stop using drugs, maintain a lifestyle free of drugs and achieve productive functioning in the family, at work and in society. Because addiction is typically a chronic disease, people cannot simply stop using drugs for a few days and halt addiction. Most patients require long term or repeated episodes of care to achieve the ultimate goal of sustained abstinence and recovery of quality of life. Research and clinical practices demonstrate the value of continued care in treating addiction, with researchers studying a variety of approaches in both residential and community settings. The future holds new research results on the influence of genetics and environment on gene function and expression, which will herald the development of personalized treatment interventions. Clinicians will integrate this information with current evidence that supports the most effective drug abuse and addiction treatments and implementation.

Effective Treatment Principles

Addiction is a complex but treatable condition that affects brain function and behavior. The abuse of drugs alters the structure and function of the brain, resulting in changes that persist long after drug use. This may explain why drug abusers are at risk for relapse even after long periods of abstinence and despite the potentially devastating consequences. No single treatment is appropriate for every user in recovery. Matching treatment settings, interventions and services to the particular problems and needs of a patient is critical to achieving success in returning to productive functioning in the family, workplace and society. Treatment needs to be readily available. Because individuals addicted to drugs may be uncertain about entering treatment, it is critical to take advantage of available services the moment people are ready for treatment. Patients can be lost if treatment is not immediately available or readily accessible. As with other chronic conditions, the earlier the user seeks treatment, the greater the likelihood of positive outcomes. Effective treatment addresses the multiple needs of the individual, not just drug abuse. To be effective, treatment must address the drug abuse and any associated medical, psychological, social, vocational and legal problems. It is also important that treatment be appropriate to the age, gender, ethnicity and culture of the user. It is critical that the user remain in treatment for an adequate recovery period. The appropriate duration for an individual depends on the type and degree of problems and needs. Research indicates that most addicted individuals need at least three months in treatment to significantly reduce or stop drug use. Studies also suggest that the best recovery outcomes occur with longer durations of treatment. Recovery from drug addiction is a long process and frequently requires multiple episodes of treatment. As with other chronic illnesses, relapses to drug abuse can occur and signifies that treatment should be reinstated or adjusted. Because individuals often leave treatment prematurely, programs should include strategies to engage and keep patients in treatment. The most commonly used forms of drug abuse treatment are counseling in individual and or groups and other behavioral therapies. Behavioral therapies vary in focus and may involve addressing a the motivation of a user to change, providing incentives for abstinence, building skills to resist drug use, replacing activities involving drugs with constructive and rewarding activities, improving problem solving skills and facilitating better interpersonal relationships. Participation in group therapy and other peer support programs during and following treatment can help maintain abstinence from drugs. Medications can be an important element of treatment for many patients, especially when combined with counseling and other behavioral therapies. For example, methadone and buprenorphine are effective in helping individuals addicted to heroin or other opioids stabilize and reduce illicit drug use. Naltrexone is also an effective medication for some individuals addicted to opioids and some patients with alcohol dependence. Other medications for alcohol dependence include acamprosate, disulfiram and topiramate. For persons addicted to nicotine, a nicotine replacement product such as patches, gum or lozenges or an oral medication such as bupropion or varenicline can be an effective component of treatment when part of a comprehensive behavioral rehab program. Doctors must modify and monitor the treatments and services for each patient to ensure that the rehabilitation meets the changing needs of the addict in recovery. A patient may require varying combinations of services and treatment components during the course of treatment and recovery. In addition to counseling or psychotherapy, a patient may require medication, medical services, family therapy, parenting instruction, vocational rehabilitation and or social and legal services. For many patients, a continuing care approach provides the best results, with the treatment intensity varying according to changing needs. Many individuals addicted to drugs also have other mental disorders. Because drug abuse and addiction, which are both mental disorders, often occur together with additional mental illnesses, doctors should carefully assess patients that present with one condition for the other. When these problems occur together, treatment should address both by the use of medication. Medically assisted detoxification is only the first stage of addiction treatment and by itself does little to change the effects of drug abuse. Although medically assisted detoxification can safely manage the acute physical symptoms of withdrawal and, for some, can pave the way for effective addiction treatment in the end, detoxification alone is rarely sufficient to help addicted individuals achieve a new lifestyle of abstinence. Thus, patients should be encouraged to continue drug treatment following detoxification. Motivational enhancement and incentive strategies, begun at initial patient intake, can improve treatment engagement. Specialists must continually monitor drug use during treatment, as patients can lapse during treatment. Another powerful motivator to get clean is if patients know that doctors monitor the drug intake of each patient. Monitoring also provides an early indication of a return to drug use, signaling the possible need to adjust the treatment plan of an individual to better meet changing needs. Drug abuse treatment can facilitate adherence to other medical treatments. Patients may be reluctant to accept screening for HIV and other infectious conditions. Specialists should encourage and support HIV screening and inform patients that highly active antiretroviral therapy can be effective in combating HIV. Treatments vary, depending on the type of drug and the characteristics of the patient. The best programs provide a combination of therapies and other services.

Acne Vulgaris

Changes in the pilosebaceous units (skin structures consisting of a hair follicle and the associated subcutaneous gland) result in acne vulgaris. Severe acne is inflammatory, but acne can also manifest in non-inflammatory forms. Acne lesions are pimples, spots or zits. Acne is most common during adolescence, affecting more than affecting more than 85 percent of teenagers, and frequently continues into adulthood. For most people, acne diminishes over time and tends to disappear, or at the very least decrease after the early twenties. There is, however, no way to predict how long acne can take to disappear entirely, and some individuals continue to suffer well into their thirties, forties and beyond. Most commonly, the face and upper neck regions are affected, but there may be acne on the chest, back and shoulders as well. Acne may appear on the upper arms, but lesions found there are often keratosis pilaris, not acne. Typical acne lesions are comedones, inflammatory papules, pustules and nodules. Some of the large nodules are cysts and nodulocystic describes severe cases of inflammatory acne.
