Factors affecting illness in the developing world: Chronic disease, mental health and traditional medicine cures
Abstract
This is a case report of a 24-year-old Ethiopian woman with a medical history of hepatosplenic schistosomiasis. She suffers from chronic liver failure and portal hypertension. She has been hospitalised for ‘hysteria’ in the past but did not receive follow-up, outpatient treatment or psychiatric evaluation. After discontinuing her medications and leaving her family to use holy water, a religious medicine used by many Ethiopians, she was found at a nearby monastery. She was non-communicative and difficult to arouse. The patient was rushed to nearby University of Gondar Hospital where she received treatment for hepatic encephalopathy and spontaneous bacterial peritonitis. Her illness is the result of neglected tropical disease, reliance on traditional medicine as opposed to biomedical services and the poor state of psychiatric care in the developing world.
... Developing world countries expose substantial heterogeneity in historical legacy of their healthcare establishments, provision and financing. Epidemiological transition in morbidity and mortality structure is probably the most notable common challenge (Douthit and Astatk, 2016). The burden of infectious diseases, nutritional disorders, and traumatism is gradually being replaced by chronic NCDs. ...
... In many resource-limited settings, access to standard medical care for neurologic disorders is limited to a few larger cities. Patients in rural areas often receive care first from traditional healers rather than trained medical professionals [2•, 11,16,17]. Traditional healers offer patients several advantages over Western-style medical care, including accessibility, affordability, relatively greater individual attention, and treatments that are considered culturally appropriate and acceptable [11, 18••]. In the best-case scenario, traditional healers may offer helpful advice for patients and can reduce crowding and congestion. ...
Purpose of Review
The goal of this review is to provide a succinct summary of issues related to the practice of child neurology in resource-limited settings. Questions addressed in this review include the comparative epidemiology of neurologic disorders affecting children in low-resource settings, changes in epidemiology over time, challenges posed by neurologic disorders in these settings, and health system-based solutions to those challenges.
Recent Findings
A number of recent epidemiological studies including the Global Burden of Disease studies have elucidated key differences in the epidemiology of neurologic disorders in low-resource setting. Neurologic disorders account for a substantial portion of the burden of disease in both high-resource and low-resource settings, but the relative prevalence of specific disorders are substantially different between these settings.
Summary
There has been a trend over the last 25 years towards a relative decrease in the prevalence of neurologic disorders secondary to communicable disorders in resource-limited settings, with a relative increase in the prevalence of noncommunicable neurologic disorders. However, the burden of neurologic disorders secondary to infectious causes and malnutrition in resource-limited settings remains substantial. Barriers to optimizing neurologic care in resource-limited settings include (1) absence of financial resources and government commitment; (2) concentration of most resources in urban areas; (3) challenges of integration of neurologic care into primary care settings; (4) scarcity of neurologic expertise; and (5) stigma associated with neurologic disorders.
Background
There is little practical guidance on how contextually relevant mental healthcare plans (MHCPs) can be developed in low-resource settings.
Aims
To describe how theory of change (ToC) was used to plan the development and evaluation of MHCPs as part of the PRogramme for Improving Mental health carE (PRIME).
Method
ToC development occurred in three stages: (a) development of a cross-country ToC by 15 PRIME consortium members; (b) development of country-specific ToCs in 13 workshops with a median of 15 (interquartile range 13–22) stakeholders per workshop; and (c) review and refinement of the cross-country ToC by 18 PRIME consortium members.
Results
One cross-country and five district ToCs were developed that outlined the steps required to improve outcomes for people with mental disorders in PRIME districts.
Conclusions
ToC is a valuable participatory method that can be used to develop MHCPs and plan their evaluation.
Background
Little is known about the service and system interventions required for successful integration of mental healthcare into primary care across diverse low- and middle-income countries (LMIC).
Aims
To examine the commonalities, variations and evidence gaps in district-level mental healthcare plans (MHCPs) developed in Ethiopia, India, Nepal, Uganda and South Africa for the PRogramme for Improving Mental health carE (PRIME).
Method
A comparative analysis of MHCP components and human resource requirements.
Results
A core set of MHCP goals was seen across all countries. The MHCPs components to achieve those goals varied, with most similarity in countries within the same resource bracket (low income v. middle income). Human resources for advanced psychosocial interventions were only available in the existing health service in the best-resourced PRIME country.
Conclusions
Application of a standardised methodological approach to MHCP across five LMIC allowed identification of core and site-specific interventions needed for implementation.
Schistosomiasis is a neglected tropical disease that ranks second only to malaria in terms of human suffering in the tropics and subtropics. Five species are known to infect man and there are currently over 240 million people infected worldwide. The cornerstone of control to date has been mass drug administration with 40 mg/kg of praziquantel but there are problems with this approach. Human and bovine vaccines are in various stages of development. Integrated control, targeting the life cycle, is the only approach that will lead to sustainability and future elimination.
Non-communicable diseases dominate the public health arena in China, yet neglected tropical diseases (NTDs) are still widespread and create a substantial burden. We review the geographical distribution, prevalence, and epidemic characteristics of NTDs identified in China caused by helminths, protozoa, bacteria, and viruses. Lymphatic filariasis was eliminated in 2007, but schistosomiasis still affects up to 5% of local village residents in some endemic counties with around 300 000 people infected. China harbours more than 90% of the world's burden of alveolar echinococcosis and food-borne zoonoses are emerging. In 2010, the overall prevalence of soil-transmitted helminth infections caused by Ascaris lumbricoides, Trichuris trichiura, and hookworm was 11·4%, with 6·8% of these infections caused by A lumbricoides. Corresponding figures for food-borne trematodiasis, echinococcosis, and cysticercosis are more than 5%. Dengue, leishmaniasis, leprosy, rabies, and trachoma exist in many areas and should not be overlooked. Transmission of vector-borne diseases can be interrupted; nevertheless, epidemics occur in remote areas, creating a challenge for surveillance and control. Rigorous surveillance, followed by immediate and integrated response packages tailored to specific social and ecological systems, is essential for progress towards the elimination of NTDs in China.
The use of herbal medicinal products and supplements has increased tremendously over the past three decades with not less than 80% of people worldwide relying on them for some part of primary healthcare. Although therapies involving these agents have shown promising potential with the efficacy of a good number of herbal products clearly established, many of them remain untested and their use are either poorly monitored or not even monitored at all. The consequence of this is an inadequate knowledge of their mode of action, potential adverse reactions, contraindications, and interactions with existing orthodox pharmaceuticals and functional foods to promote both safe and rational use of these agents. Since safety continues to be a major issue with the use of herbal remedies, it becomes imperative, therefore, that relevant regulatory authorities put in place appropriate measures to protect public health by ensuring that all herbal medicines are safe and of suitable quality. This review discusses toxicity-related issues and major safety concerns arising from the use of herbal medicinal products and also highlights some important challenges associated with effective monitoring of their safety.
Schistosomiasis is an endemic disease in Egypt caused by the trematode Schistosoma which has different species. Hepatic schistosomiasis represents the best known form of chronic disease with a wide range of clinical manifestations. The pathogenesis of schistosomiasis is related to the host cellular immune response. This leads to granuloma formation and neo angiogenesis with subsequent periportal fibrosis manifested as portal hypertension, splenomegaly and esophageal varices. Intestinal schistosomiasis is another well identified form of chronic schistosomal affection. Egg deposition and granuloma formation eventually leads to acute then chronic schistosomal colitis and is commonly associated with polyp formation. It frequently presents as abdominal pain, diarrhea, tenesmus and anal pain. Definite diagnosis of schistosomiasis disease depends on microscopy and egg identification. Marked progress regarding serologic diagnosis occurred with development of recent PCR techniques that can confirm schistosomal affection at any stage. Many antischistosomal drugs have been described for treatment, praziquantel being the most safe and efficient drug. Still ongoing studies try to develop effective vaccines with identification of many target antigens. Preventive programs are highly needed to control the disease morbidity and to break the cycle of transmission.
Background and Objective. Schistosomiasis is highly prevalent in tropics and causes morbidity and mortality in developing countries including Ethiopia. This study is aimed to assess the current status of S. mansoni infections and associated risk factors among students in Gorgora town, Northwest Ethiopia. Method. A cross-sectional study was conducted from October 2010 to November 2010 at Gorgora, Northwest Ethiopia. All students (579) present during the study period were enrolled. Pretested questionnaires were used to collect sociodemographic data and predisposing factors. Stool examination was performed using wet mount and Kato-Katz techniques. Data were entered and analysed using SPSS version 20.0 statistical software. Result. Among 579 students enrolled, 291 (50.3%) were positive for one or more intestinal parasites. Prevalence of S. mansoni was found to be 20.6% with mean intensity of infection (125 eggs per gram of feces). Lack of awareness and water contact habits such as frequent swimming in the open water source, agricultural activities on bare foot, and washing clothes were also associated with high risk of S. mansoni infection. Conclusion. Even though there seems to be a decline in the prevalence of S. mansoni infections in the study area, the problem still persists and affects students significantly. Therefore, therapeutic intervention and health education are needed.
The study aimed to investigate the types of mental illnesses treated by traditional healers, and their methods of identifying and treating mental illnesses in their patients.
In urban informal settlements of Kibera, Kangemi and Kawangware in Nairobi, Kenya, we used opportunistic sampling until the required number of traditional healers was reached, trying as much as possible to represent the different communities of Kenya. Focus group discussions were held with traditional healers in each site and later an in-depth interview was conducted with each traditional healer. An in-depth interview with each patient of the traditional healer was conducted and thereafter the MINIPLUS was administered to check the mental illness diagnoses arrived at or missed by the traditional healers. Quantitative analysis was performed using SPSS while focus group discussions and in-depth interviews were analysed for emerging themes.
Traditional healers are consulted for mental disorders by members of the community. They are able to recognize some mental disorders, particularly those relating to psychosis. However, they are limited especially for common mental disorders.
There is a need to educate healers on how to recognize different types of mental disorders and make referrals when patients are not responding to their treatments.
Background
Neglected tropical diseases (NTDs) are a group of chronic parasitic diseases and related conditions that are the most common diseases among the 2·7 billion people globally living on less than US$2 per day. In response to the growing challenge of NTDs, Ethiopia is preparing to launch a NTD Master Plan. The purpose of this review is to underscore the burden of NTDs in Ethiopia, highlight the state of current interventions, and suggest ways forward.
Results
This review indicates that NTDs are significant public health problems in Ethiopia. From the analysis reported here, Ethiopia stands out for having the largest number of NTD cases following Nigeria and the Democratic Republic of Congo. Ethiopia is estimated to have the highest burden of trachoma, podoconiosis and cutaneous leishmaniasis in sub-Saharan Africa (SSA), the second highest burden in terms of ascariasis, leprosy and visceral leishmaniasis, and the third highest burden of hookworm. Infections such as schistosomiasis, trichuriasis, lymphatic filariasis and rabies are also common. A third of Ethiopians are infected with ascariasis, one quarter is infected with trichuriasis and one in eight Ethiopians lives with hookworm or is infected with trachoma. However, despite these high burdens of infection, the control of most NTDs in Ethiopia is in its infancy. In terms of NTD control achievements, Ethiopia reached the leprosy elimination target of 1 case/10,000 population in 1999. No cases of human African trypanosomiasis have been reported since 1984. Guinea worm eradication is in its final phase. The Onchocerciasis Control Program has been making steady progress since 2001. A national blindness survey was conducted in 2006 and the trachoma program has kicked off in some regions. Lymphatic Filariasis, podoconiosis and rabies mapping are underway.
Conclusion
Ethiopia bears a significant burden of NTDs compared to other SSA countries. To achieve success in integrated control of NTDs, integrated mapping, rapid scale up of interventions and operational research into co implementation of intervention packages will be crucial.
Prior to the introduction of cosmopolitan medicine, traditional medicine used to be the dominant medical system available to millions of people in Africa in both rural and urban communities. However, the arrival of the Europeans marked a significant turning point in the history of this age-long tradition and culture. This paper examines the trends and challenges of traditional medicine in Africa. The impact of colonialism on African traditional medicine is also examined. Although the paper is on Africa, references are drawn around the world to buttress the growing demand for traditional medicine. The paper concludes that to minimise the current distrust between modern and traditional doctors and to achieve the objective of regulation, standardisation and cooperation, both traditional and modern doctors must acknowledge their areas of strengths and weaknesses from which they operate and be genuinely concerned about the difficult but necessary task of being human.
We suggest that the optimal approach to building capacity in global mental health care will require partnerships between professional resources in high-income countries and promising health-related institutions in low- and middle-income countries. The result of these partnerships will be sustainable academic relationships that can educate a new generation of in-country primary care physicians and, eventually, specialized health professionals. Research capabilities will be an essential educational component to inform policy and practice, and to ensure careful outcome measurements of training and of intervention, prevention, and promotion strategies. The goal of these academic centers of excellence will be to develop quality, in-country clinical and research professionals, and to build a productive environment for these professionals to advance their careers locally. In sum, this article discusses human capacity building in global mental health, provides recommendations for training, and offers examples of recent initiatives.
This study was aimed at investigating the distribution of a Cercopithifilaria sp. sensu Otranto et al., 2011 with dermal microfilariae recently identified in a dog from Sicily (Italy). A large epidemiological survey was conducted by examining skin samples (n = 917) and ticks (n = 890) collected from dogs at different time points in Italy, central Spain and eastern Greece.
The overall prevalence of Cercopithifilaria sp. in the sampled animal populations was 13.9% and 10.5% by microscopy of skin sediments and by PCR on skin samples, respectively. Up to 21.6% and 45.5% of dogs in Spain were positive by microscopical examination and by PCR. Cumulative incidence rates ranging from 7.7% to 13.9% were estimated in dogs from two sites in Italy. A low level of agreement between the two diagnostic tests (microscopical examination and PCR) was recorded in sites where samples were processed in parallel. Infestation rate as determined by tick dissection (from 5.2% to 16.7%) was higher than that detected by PCR (from 0% to 3.9%); tick infestation was significantly associated with Cercopithifilaria sp. infestation in dogs from two out of four sites. Developing larvae found in ticks were morphometrically studied and as many as 1469 larvae were found in a single tick.
Our data suggest that, in addition to the most common species of filarioids known to infest dogs (i.e., Dirofilaria immitis, Dirofilaria repens and Acanthocheilonema reconditum), Cercopithifilaria sp. with dermal microfilariae should be considered due to its widespread distribution in southern Europe and high frequency in tick-exposed dogs.
The WHO estimates that more than 80% of African populations attend traditional healers for health reasons and that 40%-60% of these have some kind of mental illness. However, little is known about the profiles and outcome of this traditional approach to treatment.
The purpose of this study was to describe the profiles and outcome of traditional healing practices for severe mental illnesses in Jinja and Iganga districts in the Busoga region of Eastern Uganda.
Four studies were conducted. Study I used focus group discussions (FGDs) with case vignettes with local community members and traditional healers to explore the lay concepts of psychosis. Studies II and III concerned a cross-sectional survey of patients above 18 years at the traditional healer's shrines and study IV was made on a prospective cohort of patients diagnosed with psychosis in study III. Manual content analysis was used in study I; quantitative data in studies II, III, and IV were analyzed at univariate, bivariate, and multivariate levels to determine the association between psychological distress and socio-demographic factors; for study IV, factors associated with outcome were analyzed. One-way ANOVA for independent samples was the analysis used in Study IV.
The community gave indigenous names to psychoses (mania, schizophrenia, and psychotic depression) and had multiple explanatory models for them. Thus multiple solutions for these problems were sought. Of the 387 respondents, the prevalence of psychological distress was 65.1%, where 60.2% had diagnosable current mental illness, and 16.3% had had one disorder in their lifetime. Over 80% of patients with psychosis used both biomedical and traditional healing systems. Those who combined these two systems seemed to have a better outcome. All the symptom scales showed a percentage reduction of more than 20% at the 3- and 6-month follow-ups.
Traditional healers shoulder a large burden of care of patients with mental health problems. This calls for all those who share the goal of improving the mental health of individuals to engage with traditional healers.
Little is known about the prevalence and severity of DSM-IV mental disorders treated by traditional healers in Uganda.
To describe the prevalence and severity of DSM-IV disorders handled by traditional healers in Jinja and Iganga districts, Eastern Uganda.
Between January and March 2008, Face-to-Face Interviews were conducted with 400 patients attending traditional healers' shrines for mental health problems, using Self Rating Questionnaire 25 (SRQ-25) for screening, the Mini International Neuropsychiatric Interview (MINI-Plus) for specific DSM-IV diagnosis and the Global Assessment of Functioning (GAF) for severity of illness. Descriptive data analysis and frequency estimates were performed using SPSS version 15.0 for Windows. Pearson's chi-square tests and odds ratios were used to explore the relationship between severity and combined use of biomedical services and traditional healing.
Of 387 respondents, 60.2% had diagnosable current mental illness and 16.3% had had one disorder in their lifetime. Of the diagnosable current mental illnesses, 29.7% were Psychosis; 5.4% Major depressive episode; 5.6% Anxiety disorders; 3.6% mixed Anxiety-Depression; and 3.9% Suicidality. In terms of severity, 37.7% of the current mental illnesses were severe, 35.1% moderate and 13.2% mild. Patients with moderate to severe symptoms were more likely to use both biomedical services and traditional healers. Conclusion: These findings suggest that a considerable number of patients with DSM-IV diagnosable mental disorders attend traditional healing shrines; the majority had moderate to severe symptoms. Mental health professionals therefore need to come up with ways to co-operate with traditional healers, e.g. as officially designated Traditional Mental Attendants (TMA), for the benefit of their patients.
Alternative and indigenous systems of medicine are popular amongst the poorer sections of society in the developing world. Their use in the developed world has also increased in recent times. The source and composition of these medicines vary in different parts of the world, but herbs and other botanicals are central to these systems. Largely outside the ambit of regulatory control, herbal remedies are prepared by quasi-trained herbalists and not tested for safety. Toxicity can occur when a herb with unknown toxicity is consumed, incorrect identification leads to substitution of an innocuous herb with a toxic one, preparations are contaminated with toxic non-herbal compounds or when a herb potentiates the nephrotoxic effect of a conventional therapy. Renal injury has been reported in association with several herbs. The best-known herb-induced chronic kidney disease (CKD) is aristolochic acid nephropathy. The condition is characterized by progressive interstitial nephritis, with a proportion of patients developing urothelial malignancies. The toxic compound is aristolochic acid (AA); AA-DNA adducts have been identified in the renal and urothelial tissues. Recent evidence suggests that AA also contributes to the development of Balkan endemic nephropathy. The role of herbs has been postulated in the development of CKD in other parts of the developing world, especially amongst the rural population. Public awareness and regulation of use of herbal medicines are required to eradicate this entity from the community.
Recent studies on traditional medicine (TM) have begun to change perspectives on TM effects and its role in the health of various populations. The safety and effectiveness of some TMs have been studied, paving the way to better collaboration between modern and traditional systems. Traditional medicines still remain a largely untapped health resource: they are not only sources of new leads for drug discoveries, but can also provide lessons and novel approaches that may have direct public-health and economic impact. To optimize such impact, several interventions have been suggested, including recognition of TM's economic and medical worth at academic and health policy levels; establishing working relationships with those prescribing TM; providing evidence for safety and effectiveness of local TM through appropriate studies with malaria patients; spreading results for clinical recommendations and health policy development; implementing and evaluating results of new health policies that officially integrate TM.

Many people with schizophrenia experience stigma caused by other people's knowledge, attitudes, and behaviour; this can lead to impoverishment, social marginalisation, and low quality of life. We aimed to describe the nature, direction, and severity of anticipated and experienced discrimination reported by people with schizophrenia.
We did a cross-sectional survey in 27 countries, in centres affiliated to the INDIGO Research Network, by use of face-to-face interviews with 732 participants with schizophrenia. Discrimination was measured with the newly validated discrimination and stigma scale (DISC), which produces three subscores: positive experienced discrimination; negative experienced discrimination; and anticipated discrimination.
Negative discrimination was experienced by 344 (47%) of 729 participants in making or keeping friends, by 315 (43%) of 728 from family members, by 209 (29%) of 724 in finding a job, 215 (29%) of 730 in keeping a job, and by 196 (27%) of 724 in intimate or sexual relationships. Positive experienced discrimination was rare. Anticipated discrimination affected 469 (64%) in applying for work, training, or education and 402 (55%) looking for a close relationship; 526 (72%) felt the need to conceal their diagnosis. Over a third of participants anticipated discrimination for job seeking and close personal relationships when no discrimination was experienced.
Rates of both anticipated and experienced discrimination are consistently high across countries among people with mental illness. Measures such as disability discrimination laws might, therefore, not be effective without interventions to improve self-esteem of people with mental illness.
Although therapeutic itineraries have been studied in a variety of contexts, little research has investigated care-seekers' quests for traditional medical treatments outside their own ethnic boundaries. The present study investigated 19 Igbo women seeking traditional cures from Ibibio indigenous healers in Akwa Ibom State, Nigeria. Emerging data show that these Igbo women were uptaking Ibibio indigenous treatments primarily for health conditions that have failed to respond to initial treatments in their places of origin, were stigmatized at their own places of origin, or and were thought to have resulted from supernatural causes. Care-seeking outside patients' ethnic borders was thus both a quest for a more effective treatment and a strategy for concealing therapeutic progress or and the nature of illness from the patients' places of origin. Findings underscore the critical role of culture and place in health-seeking behaviour and the need for health care services to be responsive to the complex nature of cultural organization involving care-seekers' and the critical ways this plays out in, flows into, and is negotiated through particular places during therapeutic quests.
Controlling seven tropical infections in Africa would cost just 40 cents per person per year, and would permanently benefit hundreds of millions of people.
Global and regional projections of mortality and burden of disease by cause for the years 2000, 2010, and 2030 were published by Murray and Lopez in 1996 as part of the Global Burden of Disease project. These projections, which are based on 1990 data, continue to be widely quoted, although they are substantially outdated; in particular, they substantially underestimated the spread of HIV/AIDS. To address the widespread demand for information on likely future trends in global health, and thereby to support international health policy and priority setting, we have prepared new projections of mortality and burden of disease to 2030 starting from World Health Organization estimates of mortality and burden of disease for 2002. This paper describes the methods, assumptions, input data, and results.
Relatively simple models were used to project future health trends under three scenarios-baseline, optimistic, and pessimistic-based largely on projections of economic and social development, and using the historically observed relationships of these with cause-specific mortality rates. Data inputs have been updated to take account of the greater availability of death registration data and the latest available projections for HIV/AIDS, income, human capital, tobacco smoking, body mass index, and other inputs. In all three scenarios there is a dramatic shift in the distribution of deaths from younger to older ages and from communicable, maternal, perinatal, and nutritional causes to noncommunicable disease causes. The risk of death for children younger than 5 y is projected to fall by nearly 50% in the baseline scenario between 2002 and 2030. The proportion of deaths due to noncommunicable disease is projected to rise from 59% in 2002 to 69% in 2030. Global HIV/AIDS deaths are projected to rise from 2.8 million in 2002 to 6.5 million in 2030 under the baseline scenario, which assumes coverage with antiretroviral drugs reaches 80% by 2012. Under the optimistic scenario, which also assumes increased prevention activity, HIV/AIDS deaths are projected to drop to 3.7 million in 2030. Total tobacco-attributable deaths are projected to rise from 5.4 million in 2005 to 6.4 million in 2015 and 8.3 million in 2030 under our baseline scenario. Tobacco is projected to kill 50% more people in 2015 than HIV/AIDS, and to be responsible for 10% of all deaths globally. The three leading causes of burden of disease in 2030 are projected to include HIV/AIDS, unipolar depressive disorders, and ischaemic heart disease in the baseline and pessimistic scenarios. Road traffic accidents are the fourth leading cause in the baseline scenario, and the third leading cause ahead of ischaemic heart disease in the optimistic scenario. Under the baseline scenario, HIV/AIDS becomes the leading cause of burden of disease in middle- and low-income countries by 2015.
These projections represent a set of three visions of the future for population health, based on certain explicit assumptions. Despite the wide uncertainty ranges around future projections, they enable us to appreciate better the implications for health and health policy of currently observed trends, and the likely impact of fairly certain future trends, such as the ageing of the population, the continued spread of HIV/AIDS in many regions, and the continuation of the epidemiological transition in developing countries. The results depend strongly on the assumption that future mortality trends in poor countries will have a relationship to economic and social development similar to those that have occurred in the higher-income countries.
In addition to malaria, tuberculosis, and human immunodeficiency virus infection, several other infectious diseases are associated with substantial morbidity and mortality. In particular, 13 tropical diseases infect billions of people and cause disabilities such as blindness and heart failure, especially in persons who live in impoverished conditions. This review article describes approaches to the global control of these diseases.
To summarize new knowledge on the range of disease due to chronic schistosomiasis and examine the debilitating burden of both light and heavy infection; to outline goals of disease prevention, including current age-targeted strategies and more extended programmes aimed at preventing transmission.
A systematic search of 2004-2007 papers via PUBMED and related databases using 'schistosom' and disability- or treatment-related subject headings. Reports were independently reviewed for inclusion.
Sixty-eight papers met review objectives. These suggest new evidence for a causative link between schistosome infection, antiparasite inflammation, and risk for anaemia, growth stunting and undernutrition in affected populations, as well as exacerbation of co-infections and impairment of cognitive development and work capacity. Formal quality-of-life assessment defines a significant 9.5-24% disability with the most aggressive schistosome species, Schistosoma japonicum.
Schistosomiasis represents a serious but under-recognized disease burden for many developing countries. Infection (and not intensity of infection) should be considered the defining feature of morbidity formation. Links between infection and long-term disabilities reduce the chances of combating rural poverty. Changes in our appreciation of schistosomiasis-related disease burden means it is no longer appropriate to leave infected persons untreated, and newer approaches to control should focus on preventing transmission.

WHEN THE WORLD HEALTH ORGANIZATION (WHO) EUROPEAN MINISterial Conference on Mental Health endorsed the statement "No health without mental health" in 2005,(1) it spoke to the intrinsic - and indispensable - role of mental health care in health care writ large. Yet mental health has long been treated in ways that reflect the opposite of that sentiment. This historical divide - in practice and in policy - between physical health and mental health has in turn perpetuated large gaps in resources across economic, social, and scientific domains. The upshot is a global tragedy: a legacy of the neglect and marginalization of mental health.(2) The scale of the global impact of mental illness is substantial, with mental illness constituting an estimated 7.4% of the world's measurable burden of disease.(3) The lack of access to mental health services of good quality is profound in populations with limited resources, for whom numerous social hazards exacerbate vulnerability to poor health. The human toll of mental disorders is further compounded by collateral adverse effects on health and social well-being, including exposure to stigma and human rights abuses, forestallment of educational and social opportunities, and entry into a pernicious cycle of social disenfranchisement and poverty.(4,5) Advances in efforts to alleviate the human and social costs of mental disorders have been both too slow and too few.
Summary pointsSchistosomiasis, or bilharzia, is a common intravascular infection caused by parasitic Schistosoma trematode wormsIt is prevalent in Africa, the Middle East, South America, and AsiaAcute schistosomiasis, or Katayama syndrome, can present as fever, malaise, myalgia, fatigue, non-productive cough, diarrhoea (with or without blood), haematuria (S haematobium), and right upper quadrant painChronic and advanced disease results from the host’s immune response to schistosome eggs deposited in tissues and the granulomatous reaction evoked by the antigens they secreteS mansoni, S japonicum, S intercalatum, and S mekongi cause intestinal disease; S haematobium causes urinary diseaseNeuroschistosomiasis is arguably the most severe clinical syndrome associated with schistosome infectionMicroscopic examination of excreta (stool, urine) is the gold standard diagnostic test but requires the adult worms to be producing eggs; serological tests can diagnose less advanced infectionsPraziquantel 60 mg/kg in three doses over one day (S japonicum and S.mekongi); and 40 mg/kg in doses over one day (S mansoni, S haematobium, S intercalatum) remains the treatment of choice although others are being investigatedPreventive chemotherapy is with a single oral dose of praziquantel 40 mg/kg Schistosomiasis, or bilharzia, is a common intravascular infection caused by parasitic Schistosoma trematode worms.1 2 A systematic review and meta-analysis published in 2006 estimated that more than 200 million people are infected across Africa, Asia, and South America, and close to 800 million are at risk of infection.3 Meta-analyses have estimated that the current disease burden may exceed 70 million disability adjusted life years.4 5 The disease is also associated with anaemia, chronic pain, diarrhoea, exercise intolerance, and undernutrition, and female urogenital schistosomiasis may be a risk factor for HIV infection.4 w1 5 Figure 1⇓ shows the proposed pathway of schistosomiasis associated disease and disability …
Objective:
Stigma plays a major role in the persistent suffering, disability and economic loss associated with mental illnesses. There is an urgent need to find effective strategies to increase awareness about mental illnesses and reduce stigma and discrimination. This study surveys the existing anti-stigma programmes in South Africa.
Method:
The World Health Organization's Assessment Instrument for Mental Health Systems Version 2.2 and semi-structured interviews were used to collect data on mental health education programmes in South Africa.
Results:
Numerous anti-stigma campaigns are in place in both government and non-government organizations across the country. All nine provinces have had public campaigns between 2000 and 2005, targeting various groups such as the general public, youth, different ethnic groups, health care professionals, teachers and politicians. Some schools are setting up education and prevention programmes and various forms of media and art are being utilized to educate and discourage stigma and discrimination. Mental health care users are increasingly getting involved through media and talks in a wide range of settings. Yet very few of such activities are systematically evaluated for the effectiveness and very few are being published in peer-review journals or in reports where experiences and lessons can be shared and potentially applied elsewhere.
Conclusion:
A pool of evidence for anti-stigma and awareness-raising strategies currently exists that could potentially make a scientific contribution and inform policy in South Africa as well as in other countries.
Schistosoma mansoni infection invariably results in liver fibrosis of the host. This fibrosis may be represented by small focal areas of chronic inflammation and excess extracellular matrix deposited in periovular granulomas, distributed in variable numbers at the periphery of the portal vein system. This is the outcome of 90% of the infected population in endemic areas. Conversely, a minority of infected individuals develop extensive disease with numerous granulomas along the entire extension of the portal spaces. This latter situation is mainly dependent on special hemodynamic changes created by a heavy worm load, with the subsequent production of numerous eggs and represents a severe form of a peculiar chronic hepatopathy. Thus, host-parasite interactions in schistosomiasis help us to understand a number of important features of liver fibrosis: its initiation and regulation, the significance of accompanying vascular changes, the dynamics of fibrosis formation and regression with antiparasitic treatment; host genetic and immunological contributions, and the pathophysiology of portal hypertension.
WHO and Health Action International (HAI) have developed a standardised method for surveying medicine prices, availability, affordability, and price components in low-income and middle-income countries. Here, we present a secondary analysis of medicine availability in 45 national and subnational surveys done using the WHO/HAI methodology.
Data from 45 WHO/HAI surveys in 36 countries were adjusted for inflation or deflation and purchasing power parity. International reference prices from open international procurements for generic products were used as comparators. Results are presented for 15 medicines included in at least 80% of surveys and four individual medicines.
Average public sector availability of generic medicines ranged from 29.4% to 54.4% across WHO regions. Median government procurement prices for 15 generic medicines were 1.11 times corresponding international reference prices, although purchasing efficiency ranged from 0.09 to 5.37 times international reference prices. Low procurement prices did not always translate into low patient prices. Private sector patients paid 9-25 times international reference prices for lowest-priced generic products and over 20 times international reference prices for originator products across WHO regions. Treatments for acute and chronic illness were largely unaffordable in many countries. In the private sector, wholesale mark-ups ranged from 2% to 380%, whereas retail mark-ups ranged from 10% to 552%. In countries where value added tax was applied to medicines, the amount charged varied from 4% to 15%.
Overall, public and private sector prices for originator and generic medicines were substantially higher than would be expected if purchasing and distribution were efficient and mark-ups were reasonable. Policy options such as promoting generic medicines and alternative financing mechanisms are needed to increase availability, reduce prices, and improve affordability.
Although native faith healers are found in all parts of Pakistan, where they practice in harmony with the cultural value system, their practice is poorly understood. This study investigated the prevalence, classification and treatment of mental disorders among attenders at faith healers.
The work of faith healers with 139 attenders was observed and recorded. The mental status of attenders was assessed using a two-stage design: screening using the General Health Questionnaire followed by diagnostic interview using the Psychiatric Assessment Schedule.
The classification used by faith healers is based on the mystic cause of disorders: saya (27%), jinn possession (16%) or churail (14%). Sixty-one percent of attenders were given a research diagnosis of mental disorder: major depressive episode (24%), generalized anxiety disorder (15%) or epilepsy (9%). There was little agreement between the faith healers' classification and DSM-IIIR diagnosis. Faith healers use powerful techniques of suggestion and cultural psychotherapeutic procedures.
Faith healers are a major source of care for people with mental health problems in Pakistan, particularly for women and those with little education. Further research should assess methods of collaboration that will permit people with mental health problems to access effective and culturally appropriate treatment.
Traditional healers provide a popular and accessible service across the African continent. Little is known of the characteristics or mental health status of those using these services.
To determine and compare the prevalence of common mental disorder among, and the characteristics of, those attending primary health care clinics (PHCs) and traditional healer centres (THCs) in Dar-es-Salaam.
The Clinical Interview Schedule-Revised was used to determine the prevalence of mental disorders in 178 patients from PHCs and 176 from THCs, aged 16-65 years.
The prevalence of common mental disorders among THC patients (48%) was double that of PHC patients (24%). Being older, Christian, better educated, and divorced, separated or widowed were independently associated with THC attendance. None of these factors explained the excess of mental disorder among THC attenders.
The high prevalence of mental disorders among THC attenders may reflect the failure of primary health care services adequately to detect and treat these common and disabling disorders. Traditional healers should be involved in planning comprehensive mental health care.
To measure time to initial presentation and assess factors influencing the decision to seek medical attention, we interviewed 243 patients undergoing sputum examination for the diagnosis of tuberculosis (TB) at a rural health centre near Awassa, Ethiopia. A structured questionnaire was used. Median (mean+SD) patient delay was 4.3 (9.8+12.4) weeks. Delays over 4 weeks were significantly associated with rural residence, transport time over 2 h, overnight travel, transport cost exceeding US $1.40, having sold personal assets prior to the visit, and use of traditional medicine. The majority of patients cited economic or logistical barriers to health care when asked directly about causes of delay. Case-finding strategies for TB must be sensitive to patient delay and health systems must become more accessible in rural areas.
