BackgroundThe supply of controlled drugs is limited in the Far East, despite the prevalence of health disorders that warrant their prescription. Reasons for this include strict regulatory frameworks, limited financial resources, lack of appropriate training amongst the medical profession and fear of addiction in both general practitioners and the wider population. Consequently, the weak opioid tramadol has become the analgesic most frequently used in the region to treat moderate to severe pain.MethodsTo obtain a clearer picture of the current role and clinical use of tramadol in Southeast Asia, pain specialists from 7 countries in the region were invited to participate in a survey, using a questionnaire to gather information about their individual use and experience of this analgesic.ResultsFifteen completed questionnaires were returned and the responses analyzed. Tramadol is used to manage acute and chronic pain caused by a wide range of conditions. Almost all the specialists treat moderate cancer pain with tramadol, and every one considers it to be significant or highly significant in the treatment of moderate to severe non-cancer pain. The reasons for choosing tramadol include efficacy, safety and tolerability, ready availability, reasonable cost, multiple formulations and patient compliance. Its safety profile makes tramadol particularly appropriate for use in elderly patients, outpatients, and for long-term treatment. The respondents strongly agreed that tighter regulation of tramadol would reduce its medical availability and adversely affect the quality of pain management. In some countries, there would no longer be any appropriate medication for cancer pain or the long-term treatment of chronic pain.ConclusionsIn Southeast Asia, tramadol plays an important part in the pharmacological management of moderate to severe pain, and may be the only available treatment option. If it were to become a controlled substance, the standard of pain management in the region would decline.
By injection of eosin dye with latex into 45 cadaveric fingers we were able to demonstrate: (1) a distinct digital pulp arch formed by the ulnar and radial digital arteries over the mid-point of the terminal phalanx in 93% of digits; (2) variations in size of the proper digital arteries to each digit; (3) numerous branches from the pulp arch to the tip of each digit and (4) a constant pattern of dorsal veins over the terminal segment in 89% of digits.
Chronic pain is a complex problem that eludes precise definition and can be clinically difficult to diagnose and challenging to treat. In the Asia-Pacific region, prevalence estimates that chronic pain ranges from 12% to 45% of the population, with musculoskeletal, rheumatic or osteoarthritis pain making up the majority of the disease burden. Implementation of current management guidelines into routine clinical practice has been challenging and as a result, patients with musculoskeletal pain are often poorly managed. For these reasons, a multidisciplinary Chronic Pain Advisory Board of leading physicians from various Asian countries was convened to explore ways to improve treatment and compliance, especially among patients with osteoarthritis and rheumatoid arthritis. We have identified a number of unmet therapeutic needs and prioritized initiatives with the potential to contribute toward a more integrated approach to chronic pain management. Key priorities included using evidence-based interventions as recommended by current guidelines, particularly those aspects pertinent to addressing treatment priorities in Asia (e.g., patient compliance), and the incorporation of cyclooxygenase-2 inhibitors and non-steroid anti-inflammation drugs into the management algorithms for osteoarthritis and rheumatoid arthritis. Treatment must be individualized for each patient based on efficacy, side-effect profile and drug accessibility. Further studies are required to examine head-to-head comparisons among analgesics, combinations of analgesics and long-term efficacy outcomes. Our increasing understanding of the problem combined with the promise of new therapy options offers hope for improved management of musculoskeletal pain in Asian countries.
Approximately 80% of the world's population lives in countries with little or no access to pain management. These countries also have 74% of the world's deaths from cancer and human immunodeficiency virus. Appropriate use of oral opioids can control 80%-90% of cancer pain. However, only 6.7% of the world's medical opioids are available in these low-resource countries. With the Lancet Commission on Global Surgery calling for a significant expansion of surgical services, postoperative pain management will need to be an increasing focus of our attention. There are multiple barriers to providing effective pain management. These include the type and funding of the health care system, the size and educational level of the workforce, the ease of access to effective medications, and the expectations and knowledge base of the community. Some barriers can be addressed by education at the undergraduate level, postgraduate level, and community level. Others will require continued advocacy at government level. Only when we tackle these problems will the considerable neglect of access to effective pain treatment in low- and middle-income countries be lessened.
Background and PurposeNeuropathic pain (NeuP) associated with traumatic brachial plexus injury (BPI) can be severe, persistent, and resistant to treatment. Moreover, comorbidity associated with NeuP may worsen the pain and quality of life. This study compared persistent NeuP after BPI between patients with and without co-morbid conditions (psychiatric dysfunction and other painful conditions) and tramadol usage as a second-line agent in combination with an antiepileptic and/or antidepressant during a 2-year follow-up.MethodsThe medical records of patients diagnosed with BPI referred to a pain center between 2006 and 2010 were reviewed for 2 years retrospectively. Data regarding patient demographics, injury and surgical profiles, characteristics of NeuP and its severity, and treatment received were compared between patients with and without manifesting co-morbid conditions. The NeuP and pain intensity assessments were based on the DN4 questionnaire and a numerical rating scale, respectively.ResultsOf the 45 patients studied, 24 patients presented with one of the following co-morbid conditions: myofascial pain (21%), psychiatric disorder (17%), phantom limb pain (4%), complex regional pain syndrome (21%), and insomnia (37%). Tramadol was required by 20 patients with co-morbidity and, 9 patients without co-morbidity (p<0.001). The mean pain score after 2 years was higher in patients with co-morbidity than in those without co-morbidity (p<0.05).ConclusionsPersistent pain following BPI was more common in patients manifesting other painful conditions or psychiatric co-morbidity. A higher proportion of the patients in the co-morbid group required tramadol as a second-line of agent for pain relief.
The causes and consequences of a Co-60 radiation accident in Samutprakarn Province, Thailand, were scrutinized to learn lessons aimed at preventing future radiation accidents. "Orphan sources" may end up in scrapyards. An out-of-use Co-60 medical teletherapy source, left unattended in a disused parking area belonging to a Medical Dealer, was stolen and sold to a scrap dealer in Samutprakarn Province at the end of January 2000. Because of its valuable appearance, a number of workers in the scrap trade who were not aware of radiation hazards managed to dismantle all parts. The Co-60 source was removed and left unshielded among pieces of scrap metal in the yard of the scrap shop. Some workers immediately became sick. Eighteen days later when they went to a local hospital their symptoms were recognized as radiation sickness and the incident was reported to the Office of Atomic Energy for Peace (OAEP) in Thailand. The unshielded source, with an estimated activity of 15.7 TBq (425 Ci), was retrieved soon after by an emergency team and placed in safe storage at the OAEP premises. Ten victims developed radiation sickness symptoms, of which three died soon after the accident. The accident alarmed the public, and has raised national concerns. The accident is similar in some ways to the 1987 radiation accident at Goiania, Brazil, involving a Cs-137 radiotherapy source. If not properly disposed of orphan radiation sources can lead to serious injury or even death. The accident highlights the need for security of spent high activity sources and the importance of regulatory controls.
