- Abstract
Among Oceania's population of 35 million people, the greatest number living in poverty currently live in Papua New Guinea (PNG), Fiji, Vanuatu, and the Solomon Islands. These impoverished populations are at high risk for selected NTDs, including Necator americanus hookworm infection, strongyloidiasis, lymphatic filariasis (LF), balantidiasis, yaws, trachoma, leprosy, and scabies, in addition to outbreaks of dengue and other arboviral infections including Japanese encephalitis virus infection. PNG stands out for having the largest number of cases and highest prevalence for most of these NTDs. However, Australia's Aboriginal population also suffers from a range of significant NTDs. Through the Pacific Programme to Eliminate Lymphatic Filariasis, enormous strides have been made in eliminating LF in Oceania through programs of mass drug administration (MDA), although LF remains widespread in PNG. There are opportunities to scale up MDA for PNG's major NTDs, which could be accomplished through an integrated package that combines albendazole, ivermectin, diethylcarbamazine, and azithromycin, in a program of national control. Australia's Aboriginal population may benefit from appropriately integrated MDA into primary health care systems. Several emerging viral NTDs remain important threats to the region.

- Abstract
Background: A regional trauma registry (RTR) collects injury data from multiple hospitals in a given region; however, the differences among RTRs have not yet been thoroughly investigated., Aim: The objective of this study was to identify RTRs worldwide and describe the structural differences, inclusion criteria and demographics among RTRs, as well as to investigate the effect of the inclusion criteria on patient demographics., Materials and Methods: We included state, national and multinational trauma registries in this study. We searched for RTRs using the MEDLINE database and a general Internet search engine. We abstracted the funding sources, AIS versions, data submission methods, inclusion criteria and patient demographics of each RTR. We selected the following three outcome measures for comparison: the number of case registrations per year per hospital, proportion of cases with an Injury Severity Score (ISS)>15 and crude mortality rate. We compared the outcome measures for RTRs that included 'an ISS>15', 'an admission to the Intensive Care Unit (ICU)' or 'a transferred patient for higher care' with those of RTRs that did not., Results: We identified 17 RTRs (11 national, 4 state and 2 multinational). Government funding was the most common funding source. The RTRs most frequently used the AIS 98 or AIS 2008. Web-based data submission was the most common. A significantly increased crude mortality rate was seen with 'an admission to the ICU' and 'an ISS>15'., Conclusion: We identified 17 RTRs, analysed the differences among RTRs and investigated the effect of the inclusion criteria on patient demographics. These findings may be useful when improving or developing RTRs., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

- Abstract
The Asia Oceania region contributes to more than 50% of cervical cancer cases worldwide. Yet cervical cancer is one of few cancers that can be prevented through comprehensive screening for precancerous lesions, with their subsequent treatment. Screening with cervical cytology, a very old technology, has reduced cervical cancer mortality and incidence when applied in comprehensive programs with high coverage and high quality assurance. However, of those countries within this region that have set up such programs, many have been opportunistic, had poor coverage, or inadequate treatment facilities for lesions found. Consequently, they have not seen large reductions in cancer incidence or mortality. Some have therefore adopted visual inspection by acetic acid (VIA) and Lugol's iodine (VILI) or human papillomavirus (HPV) DNA assays for screening. With two safe, immunogenic and efficacious prophylactic vaccines licensed, the way forward to reduction of cervical cancer to becoming uncommon is within reach. Where governments have supported high coverage public-health vaccination programs, reductions in disease burden with shortest incubation (genital warts, high-grade abnormalities) are already being reported. One of the biggest impediments is the cost of vaccines that are affordable to resource-poor countries. Other challenges include, infrastructure for delivery of vaccines, plus general acceptance of vaccination by the community., (©2012 AACR)

- Abstract
Context: Wide variation exists internationally for prostate cancer (PCa) rates due to differences in detection practices, treatment, and lifestyle and genetic factors., Objective: We present contemporary variations in PCa incidence and mortality patterns across five continents using the most recent data from the International Agency for Research on Cancer., Evidence Acquisition: PCa incidence and mortality estimates for 2008 from GLOBOCAN are presented. We also examine recent trends in PCa incidence rates for 40 countries and mortality rates for 53 countries from 1985 and onward via join-point analyses using an augmented version of Cancer Incidence in Five Continents and the World Health Organization mortality database., Evidence Synthesis: Estimated PCa incidence rates remain most elevated in the highest resource counties worldwide including North America, Oceania, and western and northern Europe. Mortality rates tend to be higher in less developed regions of the world including parts of South America, the Caribbean, and sub-Saharan Africa. Increasing PCa incidence rates during the most recent decade were observed in 32 of the 40 countries examined, whereas trends tended to stabilize in 8 countries. In contrast, PCa mortality rates decreased in 27 of the 53 countries under study, whereas rates increased in 16 and remained stable in 10 countries., Conclusions: PCa incidence rates increased in nearly all countries considered in this analysis except in a few high-income countries. In contrast, the increase in PCa mortality rates mainly occurred in lower resource settings, with declines largely confined to high-resource countries., (Copyright © 2012 European Association of Urology.

- Abstract
The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure defined blood pressure (BP) levels of 120 to 139/80 to 89 mm Hg as prehypertension and those of ≥ 140/90 mm Hg as hypertension. Hypertension can be divided into 3 categories, isolated diastolic (IDH; systolic BP <140 mm Hg and diastolic BP ≥ 90 mmHg), isolated systolic (systolic BP ≥ 140 mm Hg and diastolic BP <90 mmHg), and systolic-diastolic hypertension (systolic BP ≥ 140 mm Hg and diastolic BP ≥ 90 mmHg). Although there is clear evidence that isolated systolic hypertension and systolic-diastolic hypertension increase the risks of future vascular events, there remains uncertainty about the effects of IDH. The objective was to determine the effects of prehypertension and hypertension subtypes (IDH, isolated systolic hypertension, and systolic-diastolic hypertension) on the risks of cardiovascular disease (CVD) in the Asia-Pacific Region. The Asia Pacific Cohort Studies Collaboration is an individual participant data overview of cohort studies in the region. This analysis included a total of 346570 participants from 36 cohort studies. Outcomes were fatal and nonfatal CVD. The relationship between BP categories and CVD was explored using a Cox proportional hazards model adjusted for age, cholesterol, and smoking and stratified by sex and study. Compared with normal BP (<120/80 mmHg), hazard ratios (95% CIs) for CVD were 1.41 (1.31-1.53) for prehypertension, 1.81 (1.61-2.04) for IDH, 2.18 (2.00-2.37) for isolated systolic hypertension, and 3.42 (3.17-3.70) for systolic-diastolic hypertension. Separately significant effects of prehypertension and hypertension subtypes were also observed for coronary heart disease, ischemic stroke, and hemorrhagic stroke. In the Asia-Pacific region, prehypertension and all hypertension subtypes, including IDH, thus clearly predicted increased risks of CVD.

- Abstract
Background: Global, regional, and national estimates of prevalence of and tends in infertility are needed to target prevention and treatment efforts. By applying a consistent algorithm to demographic and reproductive surveys available from developed and developing countries, we estimate infertility prevalence and trends, 1990 to 2010, by country and region., Methods and Findings: We accessed and analyzed household survey data from 277 demographic and reproductive health surveys using a consistent algorithm to calculate infertility. We used a demographic infertility measure with live birth as the outcome and a 5-y exposure period based on union status, contraceptive use, and desire for a child. We corrected for biases arising from the use of incomplete information on past union status and contraceptive use. We used a Bayesian hierarchical model to estimate prevalence of and trends in infertility in 190 countries and territories. In 2010, among women 20-44 y of age who were exposed to the risk of pregnancy, 1.9% (95% uncertainty interval 1.7%, 2.2%) were unable to attain a live birth (primary infertility). Out of women who had had at least one live birth and were exposed to the risk of pregnancy, 10.5% (9.5%, 11.7%) were unable to have another child (secondary infertility). Infertility prevalence was highest in South Asia, Sub-Saharan Africa, North Africa/Middle East, and Central/Eastern Europe and Central Asia. Levels of infertility in 2010 were similar to those in 1990 in most world regions, apart from declines in primary and secondary infertility in Sub-Saharan Africa and primary infertility in South Asia (posterior probability [pp] ≥0.99). Although there were no statistically significant changes in the prevalence of infertility in most regions amongst women who were exposed to the risk of pregnancy, reduced child-seeking behavior resulted in a reduction of primary infertility among all women from 1.6% to 1.5% (pp=0.90) and a reduction of secondary infertility among all women from 3.9% to 3.0% (pp>0.99) from 1990 to 2010. Due to population growth, however, the absolute number of couples affected by infertility increased from 42.0 million (39.6 million, 44.8 million) in 1990 to 48.5 million (45.0 million, 52.6 million) in 2010. Limitations of the study include gaps in survey data for some countries and the use of proxies to determine exposure to pregnancy., Conclusions: We analyzed demographic and reproductive household survey data to reveal global patterns and trends in infertility. Independent from population growth and worldwide declines in the preferred number of children, we found little evidence of changes in infertility over two decades, apart from in the regions of Sub-Saharan Africa and South Asia. Further research is needed to identify the etiological causes of these patterns and trends.

- Abstract
Objective: To quantify the prevalence and trends of stunting among children using the WHO growth standards., Design: Five hundred and seventy-six nationally representative surveys, including anthropometric data, were analysed. Stunting was defined as the proportion of children below -2sd from the WHO length- or height-for-age standards median. Linear mixed-effects modelling was used to estimate rates and numbers of affected children from 1990 to 2010, and projections to 2020., Setting: One hundred and forty-eight developed and developing countries., Subjects: Boys and girls from birth to 60 months., Results: In 2010, it is estimated that 171 million children (167 million in developing countries) were stunted. Globally, childhood stunting decreased from 39·7 (95 % CI 38·1, 41·4) % in 1990 to 26·7 (95 % CI 24·8, 28·7) % in 2010. This trend is expected to reach 21·8 (95 % CI 19·8, 23·8) %, or 142 million, in 2020. While in Africa stunting has stagnated since 1990 at about 40 % and little improvement is anticipated, Asia showed a dramatic decrease from 49 % in 1990 to 28 % in 2010, nearly halving the number of stunted children from 190 million to 100 million. It is anticipated that this trend will continue and that in 2020 Asia and Africa will have similar numbers of stunted children (68 million and 64 million, respectively). Rates are much lower (14 % or 7 million in 2010) in Latin America., Conclusions: Despite an overall decrease in developing countries, stunting remains a major public health problem in many of them. The data summarize progress achieved in the last two decades and help identify regions needing effective interventions.

- Abstract
The prevalence of atopic eczema has been found to have increased greatly in some parts of the world. Building on a systematic review of global disease trends in asthma, our objective was to study trends in incidence and prevalence of atopic eczema. Disease trends are important for health service planning and for generating hypotheses regarding the aetiology of chronic disorders. We conducted a systematic search for high quality reports of cohort, repeated cross-sectional and routine healthcare database-based studies in seven electronic databases. Studies were required to report on at least two measures of the incidence and/or prevalence of atopic eczema between 1990 and 2010 and needed to use comparable methods at all assessment points. We retrieved 2,464 citations, from which we included 69 reports. Assessing global trends was complicated by the use of a range of outcome measures across studies and possible changes in diagnostic criteria over time. Notwithstanding these difficulties, there was evidence suggesting that the prevalence of atopic eczema was increasing in Africa, eastern Asia, western Europe and parts of northern Europe (i.e. the UK). No clear trends were identified in other regions. There was inadequate study coverage worldwide, particularly for repeated measures of atopic eczema incidence. Further epidemiological work is needed to investigate trends in what is now one of the most common long-term disorders globally. A range of relevant measures of incidence and prevalence, careful use of definitions and description of diagnostic criteria, improved study design, more comprehensive reporting and appropriate interpretation of these data are all essential to ensure that this important field of epidemiological enquiry progresses in a scientifically robust manner.

- Abstract
The aim of this paper is to describe the burden of breast cancer in the world, as the now most common cancer in women in the globe. Here a descriptive pattern based on information available in IARC and WHO databases describing estimated age-specific incidence is presented, both for incidence and mortality. The newer treatment modalities and screening programs have been developed to alleviate the burden of this disease, but much more needs to be done in the developing countries for the impact to reach outside of the developed nations.

- Abstract
Chronic pancreatitis (CP) is a disabling condition worldwide that presents as pain, maldigestion, and diabetes. It is usually perceived as alcohol related, or classified as idiopathic otherwise. However, this is true only for Western countries. Asian CP comprises not only alcohol-related CP but also tropical pancreatitis (TP). Tropical pancreatitis is a unique entity commonly found in South Asia. It shares similar presentations with other CPs for pain and maldigestion. However, its diabetes is more ketosis resistant. Non-surgical approach like endoscopic therapy plus extracoporeal shock wave lithotripsy provides better outcome for TP than other CPs, because of its less strictured pancreatic duct that is more amenable to endoscopic stone clearance. Diagnosis of CP in Asia mainly relies on image studies such as ultrasonography ± computed tomography (CT) scan, and non-invasive tests on fecal chymotrypsin, serum trypsin, and serum pancreatic isoamylase. Endoscopic ultrasonography and intestinal tubing tests are used mainly in some research centers. Autoimmune pancreatitis (AIP) is another CP originated from Asia in large series and subsequently being recognized in the West. AIP patients seldom present with maldigestion until the disease progresses to a very late stage and this occurs in less than one third of patients. In contrast, AIP is usually presented as pseudotumor of the pancreatic head, causing obstructive jaundice. Immunoglobulin G4 level is typically elevated in AIP and can be used as a marker for responsiveness. Without a need of surgery, steroids are the standard treatment. Those who relapse and are resistant to steroids should be placed on long-term immunosuppressive agents., (© 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.)

- Abstract
Chronic pancreatitis (CP) is a disease characterized by irreversible destruction and fibrosis of the parenchyma, leading to pancreatic exocrine insufficiency. In developed countries, the etiology for 60% to 70% of CP amongst male patients is alcohol and 25% are classified as idiopathic chronic pancreatitis (ICP). The genetic predisposition to CP could be an inappropriate activation of trypsinogen in the pancreas. Two common haplotypes, c.101A>G (p.N34S) and c.-215G>A, and four intronic alterations of the serine protease inhibitor Kazal type 1 (SPINK1) gene have been found to increase the risk for CP in the Asia Pacific region. Hence, SPINK1 is thought to be a candidate gene for pancreatitis. A loss-of-function alteration in chymotrypsinogen C (CTRC) gene has been shown to be associated with tropical calcific pancreatitis (TCP). Cathepsin B (CTSB) is also found to be associated with TCP. However mutations in cationic and anionic trypsinogen gene do not play an important role in causing CP in Asia Pacific region., (© 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.)

- Abstract
Purpose of Review: The burden of chronic obstructive pulmonary disease (COPD) is rapidly growing in the Asia-Pacific region. There is the need for region-specific research and analysis of the epidemiology of COPD to raise awareness of the disease and highlight its causes. Such information is essential to for the development of effective national health policies to ensure evidence-based deployment of finite healthcare resources in the prevention and management of COPD., Recent Findings: Recent population-based epidemiological studies have confirmed previous assumptions that COPD in the Asia-Pacific region is as prevalent as in the mature economies of the western world. The greatest numbers of deaths and hospitalizations from COPD are concentrated in this populous region of the world. The patterns in trends in mortality and hospitalization in the past 10 years in Asia-Pacific countries show a spectrum from the 'mature' to the 'evolving' and are likely related to the combined effects of cigarette smoking and nonsmoking risk factors. Gross underdiagnosis of COPD and underutilization of spirometry further contribute to burden and are barriers to appropriate and timely management of COPD., Summary: COPD is a common disease with a large disease burden throughout the Asia-Pacific region. Effective public health preventive measures coupled with timely case detection are needed for the reversal of trends and the reduction of disease burden.

- Abstract
Background: Imported malaria has been an increasing problem in Italy in the last three decades of the 1900s, representing the main risk for travelers visiting tropical and sub-tropical countries where malaria is endemic. Even though the total number of imported cases has been declining since 2000, malaria still represents the most frequent notifiable imported disease in Italy. The present study analyzes all the malaria cases reported in Italy in 2000-2006 in order to assess the trend of incidence over the time and reviewing the risk factors for travelers visiting malaria endemic countries., Methods: All 2000-2006 case report forms were analyzed. The incidence of malaria in Italian travelers was calculated by continent and by countries most visited, using data provided by the Ministry of Transportation., Results: Out of the 5219 malaria cases reported and confirmed in the study period five were autochthonous and 5214 imported, 1518 of which occurred in Italian citizen and 3696 in foreigners. Between 2000 and 2006 imported malaria cases fell from 977 to 630 respectively, with a total reduction of about 36%. Most of the cases were contracted in Africa (93%) and Plasmodium falciparum was the etiological agent in 83% of the cases, with an annual average fatality rate of about 0.5%. The average of the crude incidence rate (CIR) among Italians was calculated by continent for both global cases (gCIR) and for P. falciparum cases (pfCIR) resulting of 1.2/1000 and 0.9 for Africa, 0.08/1000 and 0.02 for Asia, 0.03/1000 and 0.003 for Central and South America, respectively. The gCIR by continent slightly but decreased constantly over the study period., Discussion: The different factors which may influence the risk of contracting malaria for travelers visiting endemic countries and the strategy to reduce completely the number of fatal cases were considered and discussed., (Copyright 2010 Elsevier Ltd.

This is the first article in a series of three articles on cocaine-related cardiac arrhythmias, following on from the 2008 British Pharmacological Society Winter Meeting Clinical Section Symposium entitled 'Cocaine induced cardiac arrhythmias - from ion channel to clinical treatment'. We will summarize the epidemiology of cocaine use across the world and in particular will focus on UK, Europe and US use prevalence data. We will discuss the acute cardiac and non-cardiac toxicity associated with cocaine and highlight the lack of data on the true UK prevalence of acute cocaine toxicity and on the incidence of cocaine-related cardiac arrhythmias.

- Abstract
Nasopharyngeal cancer (NPC) is endemic in Southern China, with Guandong province and Hong Kong reporting some of the highest incidences in the world. The journal Science has called it a "Cantonese cancer". We propose that in fact NPC is a cancer that originated in the Bai Yue ("proto Tai Kadai" or "proto Austronesian" or "proto Zhuang") peoples and was transmitted to the Han Chinese in southern China through intermarriage. However, the work by John Ho raised the profile of NPC, and because of the high incidence of NPC in Hong Kong and Guangzhou, NPC became known as a Cantonese cancer. We searched historical articles, articles cited in PubMed, Google, monographs, books and Internet articles relating to genetics of the peoples with high populations of NPC. The migration history of these various peoples was extensively researched, and where possible, their genetic fingerprint identified to corroborate with historical accounts. Genetic and anthropological evidence suggest there are a lot of similarities between the Bai Yue and the aboriginal peoples of Borneo and Northeast India; between Inuit of Greenland, Austronesian Mayalo Polynesians of Southeast Asia and Polynesians of Oceania, suggesting some common ancestry. Genetic studies also suggest the present Cantonese, Minnans and Hakkas are probably an admixture of northern Han and southern Bai Yue. All these populations have a high incidence of NPC. Very early contact between southern Chinese and peoples of East Africa and Arabia can also account for the intermediate incidence of NPC in these regions.

- Abstract
Background and Objective: Countries in the Asia-Pacific region have experienced an increase in the prevalence of asthma, and they have been actively involved in asthma research recently. This study aimed to analyze asthma research from Asia-Pacific in the last decade by bibliometric method., Method: Asthma articles from Asia-Pacific countries published between 1998 and 2007 were retrieved from PubMed by searching MeSH for "asthma.", Results: Most of published asthma articles in Asia-Pacific are from affluent countries in northeast Asia and Oceania. Australia and Japan have been the regional powerhouses since they contributed more than half of regional articles on asthma. Asthma publications from emerging economies in Asia such as South Korea, Taiwan, Hong Kong, and Singapore, have dramatically increased in the last decade in terms of quantity and quality aspects and were considerable sources of basic and translational research in the region. Mainland China and India have significantly increased their research capacity as well, but quality needs to be improved. Asthma publications from New Zealand and Australia, countries with the highest asthma prevalence rates in the world, yielded highest citation counts per articles and were published in journals with high impact factor. Asthma research parameters per million population correlate well with gross domestic product per capita. Almost half (41%) of total articles were produced from only 25 institutions in the region and almost half of them (47%) were published in 20 journals., Conclusions: Asthma research in Asia-Pacific were mainly conducted in countries in Oceania and Northeast Asia and research performance strongly correlated with the nation's wealth. Interesting asthma research projects in the region were recommended.

- Abstract
There are few structured data available to assess the risks associated with pandemic influenza A(H1N1)v infection according to ethnic groups. In countries of the Americas and the Pacific where these data are available, the attack rates are higher in indigenous populations, who also appear to be at approximately three to six-fold higher risk of developing severe disease and of dying. These observations may be associated with documented risk factors for severe disease and death associated with pandemic H1N1 influenza infection (especially the generally higher prevalence of diabetes, obesity, asthma, chronic obstructive pulmonary disease and pregnancy in indigenous populations). More speculative factors include those associated with the risk of infection (e.g. family size, crowding and poverty), differences in access to health services and, perhaps, genetic factors. Whatever the causes, this increased vulnerability of indigenous populations justify specific immediate actions in the control of the current pandemic including primary prevention (intensified hygiene promotion, chemoprophylaxis and vaccination) and secondary prevention (improved access to services and early treatment following symptoms onset) of severe pandemic H1N1 influenza infection.

- Abstract
Primary oral melanoma (POM) is a rare form of melanoma, generally diagnosed at a late stage and has poor prognosis. Epidemiological information has scarcely been reported in the literature over the past 40 years. Analyzing the Cancer Incidence in Five Continents volume IX (CI5-IX) database we found a total of 124,436 oral cavity cancers reported from all population-based cancer registries and 319 cases of POM reported by 67 cancer registries. To our knowledge this is the largest number of POM cases analyzed and accounts for 0.26% of all oral cavity cancers. ASR(W) for POM do not exceed 0.01 per 100,000 persons-year in all regions. The most common anatomic sites were palate (47%) and gum (27.6%) and a detailed oral mucosa examination and biopsies of nodular or macular lesions in these sites, especially on elderly patients, is advised to be routinely performed.
