ABSTRACT
The utilization of complementary and alternative medicine has increased tremendously in the last two decades. Herbal products, homeopathic medicines, and dietary supplements are extremely popular and are available without a prescription (which likely contributes to their popularity). Despite their "natural" characteristics, these remedies have the potential to cause bleeding in patients who undergo surgery. The high use of these supplements among cosmetic surgery patients, coupled with increasing reports of hematomas associated with herbal and homeopathic medicines, prompted the authors to conduct a comprehensive review focused on bleeding risks of such products in an effort to raise awareness among plastic surgeons. This review focuses on 19 herbs, three herbal formulas, two herbal teas, and several other supplements that can cause bleeding perioperatively and postoperatively. In addition to being aware of such adverse effects, plastic surgeons must adequately screen all patients and educate them on the possible dangers associated with these treatments.

BACKGROUND: As the incidence of H1N1 increases, the lay public may turn to the Internet for information about natural supplements for prevention and treatment. OBJECTIVE: Our objective was to identify and characterize websites that provide information about herbal and natural supplements with information about H1N1 and to examine trends in the public's behavior in searching for information about supplement use in preventing or treating H1N1. METHODS: This was a retrospective observational infodemiology study of indexed websites and Internet search activity over the period January 1, 2009, through November 15, 2009. The setting is the Internet as indexed by Google with aggregated Internet user data. The main outcome measures were the frequency of "hits" or webpages containing terms relating to natural supplements co-occurring with H1N1/swine flu, terms relating to natural supplements co-occurring with H1N1/swine flu proportional to all terms relating to natural supplements, webpage rank, webpage entropy, and temporal trend in search activity. RESULTS: A large number of websites support information about supplements and H1N1. The supplement with the highest proportion of H1N1/swine flu information was a homeopathic remedy known as Oscillococcinum that has no known side effects; supplements with the next highest proportions have known side effects and interactions. Webpages with both supplement and H1N1/swine flu information were less likely to be medically curated or authoritative. Search activity for supplements was temporally related to H1N1/swine flu-related news reports and events. CONCLUSIONS: The prevalence of nonauthoritative webpages with information about supplements in the context of H1N1/swine flu and the increasing number of searches for these pages suggest that the public is interested in alternatives to traditional prevention and treatment of H1N1. The quality of this information is often questionable and clinicians should be cognizant that patients may be at risk of adverse events associated with the use of supplements for H1N1.

GOALS: To examine a wide range of sociodemographic and clinical characteristics as potential predictors of complementary and alternative medicine (CAM) use among chronic liver disease (CLD) patients, with a focus on CAM therapies with the greatest potential for hepatotoxicity and interactions with conventional treatments. BACKGROUND: There is some evidence that patients with CLD commonly use CAM to address general and CLD-specific health concerns. STUDY: Patients enrolled in a population-based surveillance study of persons newly diagnosed with CLD between 1999 and 2001 were asked about current use of CAM specifically for CLD. Sociodemographic and clinical information was obtained from interviews and medical records. Predictors of CAM use were examined using univariate and multivariate logistic regression analysis. RESULTS: Of the 1040 participants, 284 (27.3%) reported current use of at least 1 of 3 CAM therapies of interest. Vitamins or other dietary supplements were the most commonly used therapy, reported by 188 (18.1%) patients. This was followed by herbal medicine (175 patients, 16.8%) and homeopathy (16 patients, 1.5%). Several characteristics were found to be independent correlates of CAM use: higher education and family income, certain CLD etiologies (alcohol, hepatitis C, hepatitis C and alcohol, and hepatitis B), and prior hospitalization for CLD. CONCLUSIONS: Use of CAM therapies that have the potential to interact with conventional treatments for CLD was quite common among this population-based sample of patients with CLD. There is a need for patient and practitioner education and communication regarding CAM use in the context of CLD.

BACKGROUND: Dietary supplements and homeopathic medicines are largely used in children as complementary and alternative medicine (CAM) to treat different health conditions. Safety of CAM is unknown when they are marketed. This study analysed suspected CAM-related adverse reaction (AR) in pediatric population. METHODS: The Italian Phytovigilance system was searched for reports of suspected AR related to CAM use in children (0-18 years) from 2002 to 2018. AR reports were evaluated and information about patient's demographic characteristics, suspected CAM, conventional medications, and ARs were collected. In particular, we evaluated whether patient's and CAM characteristics, and concomitant drugs could be potential predictors of ARs seriousness. RESULTS: We evaluated 206 pediatric CAM-related AR reports, of which 69 were serious. Patients were mostly treated with only one CAM (nâ¯=â¯193), and 39% of AR reports were related to products containing 2-5 components. Most reported ARs were related to dietary supplements (57.18%), and skin and subcutaneous tissue disorders (40.29%) were the most involved System Organ Class. CAM-related AR reported as serious were higher in subjects exposed to homeopathic medicines (ROR 3.13 [1.88-5.22]), to CAM in presence of concomitant medications (ROR 1.77 [1.01-3.10]), to CAM containing 2-4 components (ROR 2.18 [1.13-4.22]), and to more than three concomitant CAM (ROR 7.81 [1.97-32.69]). CONCLUSION: We provide new insights on factors that might increase the risk of serious AR associated with CAM use in children: products containing more than two components and simultaneously administered with conventional medications can represent a potential risk in children.

Dietary supplements are commonly used by patients as part of their medical care plan. Often clinicians may not be aware of their use, because patients do not always consider these to be medications. All clinicians need to continually ask patients about their use of dietary supplements when collecting a medication history. Dietary supplements and prescription medications often share similar enzymatic pathways for their metabolism. These interactions may lead to severe adverse reactions. This article reviews available evidence for a variety of dietary supplements in select disease categories.

Since 1991, the Medical Toxicology Unit (MTU) at Guys' Hospital, London, has been assessing the toxicological problems associated with the use of traditional and herbal remedies and dietary supplements. This assessment was carried out by evaluating reports to the National Poisons Information Service (London) [NPIS(L)] which provides emergency information to medical professionals. Relevant telephone enquiries to NPIS(L) were identified. Further case details were obtained by follow-up questionnaire, clinical consultation, toxicological analysis of samples from patients and/or products and botanical identification of plant material. Of 1297 symptomatic enquiries evaluated there was a possible/confirmed association in 785 cases. Case series have been identified which substantiate previous reports, including liver problems following the use of Chinese herbal medicine for skin disorders, allergic reactions to royal jelly and propolis and heavy metal poisoning caused by remedies from the Indian subcontinent. Although the overall risk to public health appears to be low, certain groups of traditional remedies have been associated with a number of potentially serious adverse effects. Considering the extent of use of herbal remedies and food supplements a comprehensive surveillance system for monitoring the adverse health effects of these products is essential. Surveillance of a large population is needed for the complex task of identifying the uncommon and unpredictable adverse effects which are potentially serious. In the UK, the Medicines Control Agency responded to the MTU report by recognising the need for vigilance and by incorporating adverse reactions reporting on unlicensed herbal remedies into their drug reaction monitoring function. As a further step to safeguard the patients/consumers an effective single regulatory system is required which would ensure the safety and quality of all herbal remedies and food supplements available in the UK.

Products of unknown safety and efficacy were once referred to as "quackery," and the US Food and Drug Administration (FDA) was empowered to protect public health by preventing their sale and forcing them from the market. However, in 1994, the Dietary Supplement Health and Education Act legitimized their sale as "dietary supplements." Sales increased dramatically, and many Americans now use herbals, homeopathics, and other so-called supplements. The Food and Drug Administration cannot act against them until patients have already been harmed, a dangerous situation. Furthermore, no governmental agency has the authority to force the manufacturers to furnish proof of efficacy. It is vital for physicians to warn their patients that they should use these unproven products only with great caution, and must never discontinue legitimate medical therapy in lieu of unproven products.

Concerns about the safety of oestrogen-based hormone replacement therapy after publication of the Women's Health Initiative study and Million Women Study has led to women turning to alternative therapies, erroneously believing that they are safer and 'more natural'. Evidence from randomized trials that alternative and complementary therapies improve menopausal symptoms or have the same benefits as conventional pharmacopoeia is poor. There are no recognized international criteria for the design of clinical trials of alternative therapies as there are for standard medicines and medical devices for endpoints of treatment and safety evaluations. Studies may have limitations such as design, sample size and duration. There is a wide range of different preparations, making comparison difficult. The evidence regarding botanicals, homeopathy, steroids, vitamin supplements, dietary changes and functional foods, and physical interventions are discussed in this chapter. Standard pharmacopoeia such as clonidine, selective serotonin re-uptake inhibitors and progestogens are also examined.

Alternative medicine is a heterogeneous group of treatments which has become increasingly popular in cancer patients in the Western world in recent years. We describe a 77-year-old female with chronic lymphocytic leukemia, who developed severe hyponatremia during treatment with alternative medicine given by a general practitioner over a 3-year-period. From a hematological point of view, there was no need for this expensive treatment as the disease was stable with a normal hemoglobin and thrombocyte count and no B-symptoms. The case illustrates a need for better control of the alternative practitioners and for the adverse reactions to their treatments by the National Health Service.
