ReviewPharmacotherapies for alcohol abuse. Withdrawal and treatment.
Pharmacologic management of alcoholism is only one part of the management of both alcohol dependence and withdrawal, which also includes the provision of a calm, quiet environment; reassurance; ongoing reassessment; attention to fluid and electrolyte disorders; treatment of coexisting addictions and common medical, surgical, and psychiatric comorbidities; and referral for ongoing psychosocial and medical treatment. For further discussion of these topics, the reader is referred to previously published sources. A survey of alcoholism treatment programs revealed that although benzodiazepines were the most commonly used drugs, standardized monitoring of patients' withdrawal severity was not common practice, and a significant minority of clinicians were using a variety of other drugs, some not known to prevent or treat the complications of withdrawal. ⋯ For alcohol withdrawal, however, although treatment regimens have only recently been refined, evidence for effective treatment of symptoms and prevention of complications with benzodiazepines has been available for decades. Within the last decade, effective treatments, including naltrexone, have been shown to reduce alcohol intake in alcohol-dependent persons. Given the prevalence and cost of alcohol-related problems, all effective therapies (including pharmacologic treatments) should be considered to treat alcohol abuse and dependence.

Familiarity with nonpharmacologic approaches to substance abuse treatment is critical for medical practitioners to act effectively to prevent the progression of substance use to medically harmful use, abuse, or dependence; to identify patients with substance use disorders and motivation behavioral changes; and to maximize the likelihood of successful treatment. At their most basic level, these nonpharmacologic approaches involve components of practice that are requisite to the successful management of any medical disorder: fostering an empathic, supportive relationship; routinely evaluating the system or problem area; providing accurate medical information about diagnosis, natural history, and treatment; and following up on identified problems to improve compliance, evaluate the impact of treatment, and modify treatment as indicated. Because of the nature of substance use disorders, their impact on multiple areas of functioning, and the conditioned craving that occurs following repeated substance use, nonpharmacologic treatments can improve outcome, even when effective pharmacologic treatments are also employed. ⋯ Medical practitioners must be able to educate patients about the need for more intensive specialty treatment and about what treatment entails. Medical practitioners must also be able to engage in informed discussions with substance abuse treatment specialists about the specific treatment recommendations made for a patient and the rationale for them. Medical practitioners who are informed about the treatment plans, rationale for treatment, and patient progress can play critical roles in encouraging patients to persist with the often difficult process of treatment.

ReviewPathogenesis and treatment of the antiphospholipid antibody syndrome.
Antiphospholipid antibody syndrome (APS) is one of the most important causes of thrombophilia, presenting most often as venous or arterial thrombosis, recurrent pregnancy loss, or thrombocytopenia. Both the lupus anticoagulant and anticardiolipin antibody are associated with APS. The mechanism of the prothrombotic state is not understood, but may involve beta-2 glycoprotein 1 (a naturally occurring anticoagulant), platelet aggregation, the protein C pathway, or endothelial cell function. The current treatment recommendation, after a venous or arterial thrombosis, is high-intensity, long-term warfarin therapy.

Cognitive-behavioral approaches appear to offer a viable alternative for the management of arthritis pain. Controlled studies have documented the efficacy of CBT protocols for managing pain in individuals having OA and RA. ⋯ A number of clinical and research issues need attention if CBT is to be incorporated into rheumatology practice settings. These issues include identifying the most important components of CBT, developing strategies for matching CBT interventions to patients' readiness for behavior change, testing the efficacy of different therapy formats (e.g., individual versus group), broadening the scope of CBT to address issues other than pain, and insurance reimbursement.

Chronicity and destructive potential are characteristic features of the inflammatory response in the synovial membrane typical for RA. The dominant paradigm has proposed that an exogenous antigen, likely an infectious organism, targets the synovia and elicits a chronic immune response. Support for this disease model has come from describing the cellular components of the inflammatory lesions, which are composed of macrophages, T cells, and B cells. ⋯ A sequence polymorphism in the HLA-DR B1 gene appears to be a strong genetic risk factor in several ethnic groups. Correlation of clinical presentation of RA and the inheritance of the RA risk gene suggests that the gene product is not necessary in disease initiation but functions by modulating disease pattern and severity. The next decade in RA research will be dedicated toward unraveling how genetic determinants can introduce pathology (e.g., how HLA genes can function as progre
