Nicotine-replacement therapy: A proven treatment for smoking cessation

Smoking is a major cause of cardiovascular diseases, respiratory diseases and cancer. Despite the high prevalence of smokers worldwide, smokers are often neglected and not offered effective assistance with quitting their habits. In order to overcome this public health burden, effective treatment is needed to help smokers stop smoking. Among the pharmacological treatments available, nicotine-replacement therapy (NRT), when prescribed in combination with behavioural support, has been proven to be effective in helping a wide range of smokers to quit. NRT helps smokers during the withdrawal process by replacing a proportion of the nicotine formerly obtained from cigarettes. NRT is available in many formulations. The commonly prescribed formulations are nicotine gum, nicotine patches, nicotine inhaler and nicotine nasal spray. The choice of which NRT to prescribe depends on the patient’s condition, established guidelines and protocols and availability. This article aims to review the role of NRT in smoking cessation

A case of cutaneous larva migrans acquired from soiled toilet floors in urban Kuala Lumpur

Despite being a common skin dermatosis in the tropics, physicians in the tropics may miss the diagnosis of cutaneous larva migrans for other pruritic skin manifestation. This is especially in those who live in urban housing with no history of travel. Cutaneous larva migrans, an intensely pruritic skin pathology is mainly contracted by people with history of beach holiday or contact with moist soft sand which had been contaminated with dog or cat faeces. This article reports a patient who presented with intensely itchy papular spots over the dorsum of his foot after walking barefooted in an urban toilet soiled with cat faeces. The patient had initially seen an urban general practitioner who diagnosed the papular skin lesion as an allergic reaction, and prescribed antihistamines. The patient subsequently developed creeping skin lesions and was seen by the author who prescribed albendazole 400 mg twice daily for three days. The patient reported reduction in itching after two days of albendazole treatment and a follow up at ten days revealed a healed infection

Itraconazole-induced Torsade de Pointes in a patient receiving methadone substitution therapy

Issues. Methadone, a pharmacological agent used to treat heroin dependence is relatively safe, but may cause cardiac arrhythmias in the concurrent presence of other risk factors. Approach and Key Findings. This case report highlights the risk of Torsade de Pointes, a life-threatening cardiac arrhythmia, in a heroin-dependent patient receiving methadone substitution therapy who was prescribed itraconazole for vaginal thrush. The patient presented to the accident and emergency department for chest discomfort and an episode of syncope following two doses of itraconazole (200 mg). Electrocardiogram monitoring at the accident and emergency department showed prolonged rate-corrected QT interval leading to Torsade de Pointes. The patient was admitted for cardiac monitoring, and electrocardiogram returned to normal upon discontinuation of methadone. Implication. This cardiac arrhythmia was most likely as a result of a drug interaction between methadone and itraconazole because the patient presented with no other risk factors. Conclusion. Given the benefits of methadone as a substitution treatment for heroin-dependent individuals, the association between methadone and cardiac arrhythmias is of great concern. Physicians treating heroin-dependent patients on methadone substitution therapy should therefore be cautious of the potential risk of drug interactions that may lead to fatal cardiac arrhythmias

Heroin addiction: the past and future

Substance misuse, in particular heroin addiction contributes to health and social problems. Although effective medical treatment was available, earlier efforts confined the treatment of heroin addicts to in-house rehabilitation which required them to be estranged from the community and their families for 2 years. The in-house rehabilitative programme, implemented for at least three decades has produced low abstinence rates. On the other hand, being ‘away’ meant that many heroin addicts faced employment problems and family relationship difficulties upon completing the in-house rehabilitation. However, recently, the concerted efforts by various government and non-government organisations, and the acknowledgement that heroin addiction is a medical illness has resulted in a revamp to approaching treatment of heroin addiction. At present, methadone substitution programmes have been offered as part of treatment programme for heroin addicts in Malaysia. This new programme has been shown to be effective in treating heroin addiction and would need support and cooperation from all groups involved

Illicit ketamine induced frequency of micturition in a young Malay woman

Issues. The growing use of illicit ketamine among young adults poses a public health concern in Malaysia. In contrast to medical use of ketamine, illicit use has been reported to produce adverse effects on the urinary tract and, in particular the bladder. Approach and Key Findings. This case report describes a young Malay woman who developed severe bladder symptoms (urinary frequency) after consuming illicit ketamine. A history of illicit ketamine use was initially missed, and she was consequently diagnosed and treated for a urinary tract infection. Her symptoms persisted despite several courses of antibiotics. The patient was subsequently referred to an urologist where cystoscopic examination and biopsy of the bladder found changes consistent with interstitial cystitis. This was despite the absence of haematuria. Renal function was normal. Implication. The patient's ketamine use was the most likely cause for the urinary symptoms and bladder changes. Conclusion. Illicit ketamine use may lead to severe urinary tract problems that can be irreversible even after ketamine has ceased. Early diagnosis is critical although difficult when ketamine use is not divulged during the consultation with the physician. Physician consideration of this new clinical entity is important, particularly in cases where the symptoms do not resolve with usual treatment

A Fifty-year challenge in managing drug addiction in Malaysia

The history of substance abuse in Malaysia can be divided into pre- and post-independent era. In pre-independence, the main drug of abuse was opium which was initially consumed by immigrants from China who were introduced by the British colonialist to work in \ud Malaya. The post-independence era began in the 1960s when young adults were inß uenced by the “Hippy” subculture. At this time, consumption patterns changed where more Malays were involved in drug abuse compared to other ethnic groups (1, 2). \ud By the early 1980s, the prevalence of drug addiction increased and this increasing trend made the Malaysian government consider heroin addiction as a national threat. The national anti-drug task force was formed to control trafÞ cking and to rehabilitate addicts who \ud were involved in heroin addiction (3). Legislation was introduced where mandatory death sentence was implemented for those who smuggled more than 15 grams of heroin. Drug addicts found to be positive for heroin were forced to undergo compulsory \ud rehabilitation for two years (4). Nationwide, up to 28 government drug rehabilitation centres were established, and at any particular period, each centre accommodated up to 500 inmates. Approximately RM50 million a year was spent to run these centres (5). The centres were initially managed on a total abstinence philosophy; however this approach produced poor results. The latest survey showed that 85% of drug addicts relapsed after completing their rehabilitation at these centres (4, 6). In view of the poor results, substitute treatment with methadone was introduced recently to these centres (7).One of the visions of the Malaysian government was to create a drug addiction free nation by the year 2015. However, the increasing number of drug addicts has caused a surge in demand for rehabilitation centres, resulting in the inability of these centres to cope. For example, the number of drug addicts increased by 1% from year 2001 to 2002, but the number of drug addicts detected in year 2003 was 36,996, a 16% jump from the previous year (31,893). Furthermore, the National Drug Agency reported that 45% of the cases were repeat addicts. As for distribution of new cases, by ethnic group the Malays constituted 71%, Chinese 10.6% and Indian 8.2%. The majority (70%) were in the socially and economically most productive age group (20-39 years) and almost 98% of the addicts who occupied these rehabilitation centres were male. Currently, the number of drug users in the country is estimated to be 250,000 but the number is predicted to reach half a million by year 2015 (3, 8-10). The resulting economic,human resource and social loss is not quantiÞ able as the vacuum left by these people in various employment sectors are currently being Þ lled by migrant workers. Thus, it is evident that the increasing trend in drug addiction poses a threat to the future of the nation (1, 6, 9)

Organ transplants: ethical, social, and religious issues in a multicultural society

"Recent advances in the fields of organ donation and organ transplant have introduced new hope for the treatment of serious diseases. However, this promise has been accompanied by several issues. The most common issue raised is ethical implications, but in a multicultural society like Malaysia, additional concerns arise pertaining to social and religious issues. These concerns needs to be addressed as attitudes toward and acceptability of organ donation varies according to social, culture, and religion. The diverse cultural, religious, and traditional concepts pertaining to organ donation may hamper its acceptability and cause a lack of willingness to donate organs. The purpose of this article is to briefly explore the ethical issues involved in organ transplant and the various religious opinions on organ donation. It is hoped that this knowledge and understanding may benefit both health care providers and patients in a multicultural society like Malaysia." [author's abstracts

The transition to harm reduction: Understanding the role of non-governmental organisations in Malaysia

Background: The transition of drug policy from prohibition to harm reduction has never been easy. The deeply entrenched belief in prohibition shared by policy makers and religious leaders provided little room for alternatives, and change came only slowly. The non-governmental organisations (NGOs) in Malaysia played a pivotal role in effecting such a change. Understanding how they did so may be instructive for other similarly placed countries. Methods: Data collected via reviews of published secondary sources, media reports and in-depth interviews with pioneers of harm reduction drawn from NGOs, medical practitioners and the police were analysed to construct the paper. Results: The policy change was the outcome of competition between three groups in the drug policy subsystem - the state, the Muslim religious lobby and the NGOs. Developments such as the poor outcomes from the prohibition programmes and the outbreak of HIV/AIDS did not change policy but did lead to a rethink of core beliefs in the state alliance and spawned a state-NGO partnership. The subsequent failure to meet the Millennium Development Goal with respect to HIV/AIDS in 2005 - was seen as a failure of the Health Ministry which then led the final charge for a policy change arguing that a health crisis was imminent. The NGOs played a pivotal role in this process by educating their partners in the state coalition, by drawing academics and medical practitioners into advocacy and by engaging the religious lobby (albeit with varying success). They were also frontline players in implementing harm reduction programmes and successfully deflected criticisms from unconvinced Islamic groups away from the state. Conclusion: Given their central role in the needle-syringe exchange programme, the NGOs are well positioned to convince injecting drug users to opt for voluntary medical treatment. This can potentially reduce both the harm from drug use and the prevalence of it. (C) 2011 Elsevier B.V. All rights reserved.

Salivary nicotine and cotinine concentrations in unstimulated and stimulated saliva

Salivary nicotine and salivary cotinine is widely used in clinical and epidemiological studies to validate smoking cessation. However, the reported collection for salivary nicotine and salivary cotinine vary by technique and duration. This study investigated the influence of salivary collection by unstimulation and stimulation technique of the concentration of salivary nicotine and salivary cotinine. It was found that unstimulated technique produced the highest salivary nicotine concentration, whereas stimulated technique produced the highest salivary cotinine concentration. The results of this study suggest that it is important to standardise salivary nicotine and cotinine collection technique.
