Pharmacokinetic properties of single-dose primaquine in Papua New Guinean children: feasibility of abbreviated high-dose regimens for radical cure of vivax malaria. Tolerability and safety of primaquine in Papua New Guinean children 1 to 10 years of age. Evaluation of the safety and tolerability of a short higher-dose primaquine regimen for presumptive anti-relapse therapy in healthy subjects. Clinical trial of oral artesunate with or without high-dose primaquine for the treatment of vivax malaria in Thailand. It is widely distributed throughout the body and is detectable in cerebrospinal fuid, breast milk and the placenta (2). The initial metabolite, 3-hydroxyquinine, contributes approximately 10% of the antimalarial activity of the parent compound. Up to 20% of administered drug is excreted unchanged by the kidneys, and small amounts may appear in bile and saliva (34, 35). Pharmacokinetic parameters of quinine reported with currently recommended doses used for the treatment of patients with severe or uncomplicated malaria (range of mean or median values reported). Both the apparent volume of distribution and systemic clearance are reduced in proportion to disease severity, resulting in higher plasma quinine levels in patients with severe malaria. As a result, quinine accumulates with standard maintenance dosing regimens (10 mg salt/kg bw every 8 h), unless the patient starts to recover. As a consequence, if there is no clinical recovery within 48 h, the dosage is reduced by one third (to 10 mg salt/kg bw every 12 h). In patients who are in acute renal failure, quinine clearance is determined by the overall disease severity and hepatic function. In addition, plasma-protein binding, mainly to the acute-phase protein α1-acid glycoprotein, increases from about 80% in healthy subjects to around 90% in patients with malaria (36). The exposure of pregnant women to quinine was generally lower and elimination more rapid than that in non-pregnant patients (23, 28). The disposition of quinine changes with age, with slightly higher concentrations observed in children < 2 years (24). In children with protein energy malnutrition, clearance is signifcantly reduced, the elimination half-life is signifcantly longer but the maximum concentration signifcantly lower than in controls (20, 31, 32). Quinine pharmacokinetics, including total clearance normalized to ideal body weight, is not signifcantly altered in A obese patients; thus, the maintenance dose of quinine in these patients should 5 be based on ideal body weight rather than on total body weight (6, 33). Quinine clearance is signifcantly lower in elderly patients, posing a potential risk for drug accumulation and toxicity (26). Safety Adverse events Because of its narrow therapeutic index, quinine has frequent adverse effects (2, 6, 8, 28, 37). The side-effects commonly seen after administration of treatment doses are referred to as “cinchonism”. Mild forms are characterized by tinnitus, slight impairment of hearing, headache, nausea, dizziness, dysphoria and sometimes disturbed vision. More severe manifestations include vertigo, vomiting, abdominal pain, diarrhoea, marked auditory loss and visual symptoms, including loss of vision. An important side-effect of quinine is hyperinsulinaemic hypoglycaemia, which is particularly common in young children, pregnant women and elderly patients. Hypotension and cardiac arrest may occur if the drug is given too rapidly (such as in an intravenous bolus); intravenous formulations should therefore be given by infusion not exceeding a rate of 5 mg/kg bw per hour. Venous thrombosis may occur after intravenous administration, while pain, necrosis and abscess formation may occur with acidic intramuscular injections. Hypersensitivity reactions to quinine have also been reported, including urticaria, bronchospasm, fushing of the skin, fever, antibody-mediated thrombocytopenia, haemolytic anaemia and haemolytic–uraemic syndrome. Quinine has been used as an abortifacient, but there is no evidence that it causes abortion, premature labour or fetal abnormalities (28, 34). Quinine therefore remains the drug of choice during the frst trimester of pregnancy. It may also be used safely in the second and third trimesters of pregnancy, although poor compliance because of 7-day treatment course and low tolerability may compromise its effcacy, and there is a high rate of hyperinsulinaemic hypoglycaemia. Overdosage of quinine may cause oculotoxicity, including blindness from direct retinal toxicity, and cardiotoxicity, and can be fatal (38). Cardiotoxic effects include conduction disturbances, angina and hypotension leading to cardiac arrest. Treatment is largely supportive, with particular attention to maintenance of blood pressure, glucose and renal function and to treating any arrhythmias. Contraindications Quinine is contraindicated in patients with known hypersensitivity to quinine or any of the cinchona alkaloids. Caution Although caution should be exercised when administering quinine to patients who have heart rhythm disorders or heart disease, there is little evidence of cardiotoxicity in patients with malaria. Caution is also advised in treating patients with kidney or liver disease, as the drug may accumulate (10, 18, 19, 39–41).

Sengupta (2008) notes that medical tourism facilities allow increased rate of depreciation on life saving equipments generic 1mg coumadin visa blood pressure medication kidney pain, and also prime land at subsidised rates purchase cheapest coumadin blood pressure medication without food. In Malaysia order coumadin 5mg visa blood pressure medication kinds, the National Committee for Promotion of Medical and Health Tourism was formed by the Ministry of Health in 1998 discount coumadin online amex arterial. It developed a strategic plan and networked both domestically and overseas with relevant interests. Toyota (2011) suggests that the medical tourism markets of both Singapore and Dubai, alongside those of India, Thailand, and Malaysia should be considered as the ‗first wave‘ of Asian medical tourism. She points to the post-2008 expansion of both the Japanese and South Korean medical tourism markets as representing a second wave, one marked by increasing state involvement. In the Japanese case, the low numbers of trained doctors and high cost of treatment has severely constrained the growth of the medical tourism market (Hall, 2009, Toyota, 2011, p. Indeed, as Connell highlights, Japan has until recently been primarily thought of as a source country rather than a destination country in terms of medical tourism, with large numbers of Japanese citizens travelling abroad for healthcare (Connell, 2006, p. The Japanese government has recently outlined plans to reverse the outbound medical tourism trend, rolling out a new organisation with the sole aim of increasing inbound medical tourism. The rationale being that Japan cannot compete with the lower costs offered in such markets and thus should concentrate on the types of procedure where access and quality are the primary motivations for medical tourism rather than simply the cost (Hall, 2009). In contrast to Japan, the Korean government have matched their commitment to the expansion of the inbound medical tourism market with investment in a market to directly compete with other Asian countries. The high quality and low cost of treatment is also being used as part of a targeted campaign to encourage Korean expatriates and members of Korean communities in countries such as the United States and New Zealand (Lee et al. As with Asian countries, State involvement varies from country to country with a mixture of private and public facilities catering for medical tourism. In Poland, a popular destination for dental tourists and cosmetic tourists, medical tourism is facilitated through private companies, many of the clinics used are state-owned, serving Polish citizens alongside medical tourism. This reflects the Polish government‘s desire to capture the potential of medical tourism and marked by the creation of the Polish Medical Tourism Chamber of Commerce (Reisman, 2010, p. While many of the clinics offering treatment to medical tourists are undoubtedly private, the role of the Hungarian government should not be overlooked. Beyond national strategies there a range of ways that national policy can directly foster the domestic medical tourism industry. There are a range of organisational dimensions related to the quality and safety of medical treatment abroad. Many of these are not necessarily unique to medical tourism in that health care is replete with information asymmetries and potential threats to the quality and safety of patient care pathways, but these are intensified given the dimensions of ―distance‖ including legal jurisdiction. Ideally, a common regulatory platform and reporting system would serve as the basis of an assessment of comparative quality of care using a range of performance indicators as facilitated by international accreditation and certification. Presently, there is a lack of comparative quality and safety data, and knowledge of infection rates for overseas institutions and reporting of adverse events is lacking. Importantly, bodies like the World Health Organisation have yet to publish any firm guidance on this and there does not appear to be any immediate intention to do so. For some, a lack of transparency on quality is an impediment to a fully developed market in medical tourism (Ehrbeck et al. Availability of evidence about the quality of a particular surgeon or clinical team, some suggest, would encourage more people to pursue medical tourism (Unti, 2009). As with all medical treatments, an element of risk exists to the patient‘s health, which is supposedly outweighed by the potential benefits resulting from the treatment. What can be gleaned from the literature concerning risk and safety-related incidents for medical tourism is limited. Medical tourism adds a new dynamic to this element of risk, due to the overseas travel involved. Travelling when unwell can lead to further health complications, including the possibility of deep vein thrombosis (Crooks et al. Despite medical tourism involving air travel, there is no published evidence on travel risk resulting from medical tourism, for example on thrombosis. Relatively little is known about the experience and satisfaction of medical tourists. Patient clinical outcomes and satisfaction do not necessarily go together and satisfaction is not always the primary indicator for some treatments such as dental work. Similarly, with regard to cosmetic surgery there is evidence that a small percentage of patients may suffer from psychological body-related issues that make such judgements problematic (Grossbart and Sarwer, 2003). Conversely, Hanna et al (2009) note that for a sample of outsourced patients (rather than medical tourists) whilst the majority of patients operated upon abroad obtained comparable functional results with those expected locally, they were often dissatisfied with the overall experience. There is a gap 24 in understanding of patient expectations and how these may be raised by individuals paying a market-price and taking responsibility for choosing a provider. Evidence of clinical outcomes for medical tourist treatments is limited and reports are difficult to obtain and verify. Little is known about the relative clinical effectiveness and outcomes for particular treatments, institutions, clinicians and organisations. There is scant evidence on long or short-term follow- up of patients returning to their home countries following treatments at the range of destinations. That a positive treatment outcome should result is important, not least because the patient‘s local health care provider takes on the responsibility and funding for post-operative care including treatment for complications and to remedy side-effects (Cheung and Wilson, 2007). In the event of an adverse outcome, it should be known whether, and to what extent, the patient has recourse for redress. Patient follow-up by providers is rare; a study of 20 patients presenting at a German university hospital after overseas refractive surgery concluded that there was insufficient management of complications and a lack of post-operative care (Terzi et al. For ‗transplant tourism‘, Canales‘ (2006) study of kidney patients transplanted abroad found that there was a high incidence of serious post- operative infections (6 serious infections for 4 patients), although graft survival and function were concluded to be good – see also Geddes‘ follow-up of kidney patients who had travelled from Scotland to Pakistan for treatment (Geddes et al. In an audit of the pan-Thames region, 35 out of 65 consultants replied to requests about cosmetic surgery impacts (Birch et al. Sixty per cent of those replying had seen complications and the majority of these cases (66%) were emergencies that required inpatient admission. Australian research on professionals raises a similar issue (MacReady, 2007) and there are detailed case studies of detrimental outcomes from surgery abroad incurring significant public costs to rectify poor outcomes (Cheung and Wilson, 2007). In terms of dental treatment abroad there are some reported cases of complications having to be dealt with by the home health system. Barrowman et al (2010) report cases histories of five Australian travellers requiring attention by oral and maxillofacial surgeons because of dental implants. In sum, relatively little is known about readmission, morbidity and mortality following self- funded medical treatment abroad (see also Balaban and Marano, 2010). The overseas and private nature of delivery explains why there is such a dearth of information relating to clinical outcomes, post-operative complications, lapses in safety and poor professional practice (cf Alleman et al. It is ethical to ensure that patients are as well cared for as possible and, to this end, patients should receive appropriate advice and input at all stages of the caring process. When medical treatment is sought abroad, the normal continuum of care may be interrupted. It is useful to consider the cycle of care through all its possible stages, pre- or post- the period of hospital care. Canales‘ (2006) study of kidney transplants, for example, concludes there was inadequate communication of information – immunosuppressive regimens and preoperative information. The medical traveller is usually in hospital for only a few days or even weeks, and then may go on the vacation portion of their trip or return home, when complications, side-effects and post-operative care then become the responsibility of the healthcare system in the patients‘ home country.

Primary infection is characterised by: » glandular fever-type illness » maculopapular rash » small orogenital ulcers After primary infection patients have generalised lymphadenopathy and are usually asymptomatic for several years. Subsequently inflammatory skin conditions and an increased frequency of minor infections occur, followed by more severe infections (especially tuberculosis), weight loss or chronic diarrhoea. Examples of conditions in this category includes but is not limited to: Immune Thrombocytopenic Purpura and Thrombotic Thrombocytopenic Purpura. If efavirenz is contra-indicated nevirapine can be used, but the lead-in dose of nevirapine must be omitted. Note: Cotrimoxazole hypersensitivity is common and usually presents as a maculopapular rash. If there are systemic features or mucosal involvement associated with the use of cotrimoxazole, the medicine must be immediately and permanently stopped and the patient referred to hospital. Herpes simplex, histoplasmosis and mycobacteria may also present with major mucosal ulcers. If CrAg test is positive and the patient has any symptom of meningitis: Refer patient immediately for lumbar puncture. Secondary prophylaxis After completion of fluconazole 400 mg daily for 8 weeks: Fluconazole, oral, 200 mg daily for a minimum of 12 months. If stool shows Isospora belli: Cotrimoxazole, oral, 320/1600 mg (4 tablets) 12 hourly for 10 days. Treatment is not generally recommended because it is mostly of only cosmetic importance and therefore the risk of systemic therapy is not warranted. For prolonged pain occurring after shingles has healed (post herpetic neuralgia), or if pain not responding to paracetamol and tramadol: Amitriptyline, oral, 25 mg at night.

Failure to achieve adherence and understanding may lead to resistance and adversely affect the prognosis of the child. If medical contraindications are present refer to hospital for rapid review and planning. Social issues that must be addressed to ensure successful treatment These are extremely important for success and impact on adherence. Disclosure to another adult living in the same house is encouraged so that there is someone else who can assist with the child’s treatment. All efforts should be made to ensure that the social circumstances of vulnerable children (e. If ≥ 1 antiretroviral is missing from the medicine regimen, treatment should be stopped until they are all available again.
