Effective use of action-oriented studies in Pakistan.

Little formal research has been done in special education and rehabilitation in Pakistan because of a lack of basic groundwork and trained researchers. However, the absence of formal structures permits innovative approaches. Several low-cost, action-oriented participatory studies have been carried out at the Mental Health Centre, Peshawar. These have ranged from community survey exercises to more complex studies of attitudes towards disability, childhood developmental skills, trends in polio paralysis and casual educational integration. The studies were undertaken in collaboration with education and welfare authorities. Formal and informal channels were used to disseminate the study findings widely in Pakistan and many other countries, and to generate an on-going movement for policy development and service provision. This article summarizes results from some of these studies. It also considers problems associated with the dissemination of special education and rehabilitation research findings in developing countries like Pakistan.

Genetic divergence of poliovirus strains isolated in the Karachi region of Pakistan.

Seventy-seven wild poliovirus strains isolated from poliomyelitis cases in the Civil Hospital of Karachi in Pakistan in 1989-1993 were selected for partial sequence analysis covering the VP1/2A junction region of the viral genome to study the genetic relationships and epidemiological links between strains. Viral RNA was partially amplified by RT-PCR and sequenced by a solid phase method. Computer analysis revealed genetic divergence of the strains within each serotype. Most of the nucleotide differences between strains were silent: only a few specific amino acid substitutions were seen in the sequenced region. Three genotypes of poliovirus type 1 and two of poliovirus type 3 were co-circulating, while type 2 strains were represented by a single genotype. Representatives of all the genotypes present have been found among previously or concurrently characterized stains isolated elsewhere, but direct epidemiological links were found only in the case of serotype 1. Many of the epidemics caused by poliovirus type 1 in other countries were genetically linked to Pakistan. This study clearly shows the endemic circulation and wide variation of all three poliovirus serotypes in southern Pakistan and indicates the need for more effective vaccination programmes to prevent the further spread of these wild viruses.

Adult anopheline ecology and malaria transmission in irrigated areas of South Punjab, Pakistan.

Surface irrigation in the Punjab province of Pakistan has been carried out on a large scale since the development of the Indus Basin Irrigation System in the late 19th century. The objective of our study was to understand how the population dynamics of adult anopheline mosquitoes (Diptera: Culicidae) could be related to malaria transmission in rural areas with intensive irrigation and a history of malaria epidemics. In this paper we present our observations from three villages located along an irrigation canal in South Punjab. The study was carried out from 1 April 1999 to 31 March 2000. Mosquitoes were collected from bedrooms using the pyrethroid spraycatch method and from vegetation and animal sheds using backpack aspirators. Overall, Anopheles subpictus Grassi sensu lato predominated (55.6%), followed by An. stephensi Liston s.l. (41.4%), An. culicifacies Giles s.l. (2.0%), An. pulcherrimus Theobald (1.0%) and An. peditaeniatus Leicester (0.1%). Most mosquitoes (98.8%) were collected from indoor resting-sites whereas collections from potential resting-sites outdoors accounted for only 1.2% of total anopheline densities, confirming the endophilic behaviour of anophelines in Pakistan. Anopheles stephensi, An. culicifacies and An. subpictus populations peaked in August, September and October, respectively. High temperatures and low rainfall negatively affected seasonal abundance in our area. There were interesting differences in anopheline fauna between villages, with An. culicifacies occurring almost exclusively in the village at the head of the irrigation canal, where waterlogged and irrigated fields prevailed. Monthly house-to-house fever surveys showed that malaria transmission remained low with an overall slide positivity rate of 2.4% and all cases were due to infection with Plasmodium vivax. The most plausible explanation for low transmission in our study area seems to be the low density of Pakistan's primary malaria vector, An. culicifacies. The role of other species such as An. stephensi is not clear. Our observations indicate that, in South Punjab, irrigation-related sites support the breeding of anopheline mosquitoes, including the vectors of malaria. As our study was carried out during a year with exceptionally hot and dry climatic conditions, densities and longevity of mosquitoes would probably be higher in other years and could result in more significant malaria transmission than we observed. To assess the overall importance of irrigation-related sites in the epidemiology of malaria in the Punjab, more studies are needed to compare irrigated and non-irrigated areas.

Nursing as a career choice for women in Pakistan.

This paper reports on semi-structured interviews with 114 Pakistani nurses. This sample comes from a larger long-term study examining the impact of advanced training in Canada on the lives and careers of nurses and lady health visitors from Pakistan. The data reported here were drawn from the first interview with all nurses, and focuses on how and why they chose a career in nursing. Demographically, the respondents (Rs) were more urban and more highly educated than the average Pakistani woman. Compared to the national population, Ismailis and Christians were over-represented and non-Ismaili Muslims under-represented in our sample. Although these ratios are also true of Pakistan's nursing population, the bias has been exaggerated by the convenience nature of our sample drawn primarily from the Aga Khan University Medical Centre. Most Rs found out about nursing through a relative or friend who was also a nurse. Eighty per cent of Rs (n = 92) reported having made the decision to pursue nursing by themselves, illustrating the increasing ability of women to control their own lives in this traditionally patriarchal society. 'Professionalism' was the predominant reason why Rs (or others) decided on nursing, followed by 'Altruism'. These findings are compared to other studies on the career choice of nurses done in non-Islamic societies. Over 90% of Rs reported receiving support from at least one friend or relative for their decision to enter nursing. Nonetheless, over half (58%) also reported that someone, most often a male relative, had opposed their career choice. Our results are discussed in terms of the status of women and nursing in Pakistan.

Molecular analysis of HLA allele frequencies and haplotypes in Baloch of Iran compared with related populations of Pakistan.

The extreme polymorphism in different loci of the human leukocyte antigen (HLA) system has been used as an invaluable tool for anthropological studies. Determination of HLA allele and haplotype frequencies in different ethnic groups is useful for population genetic analyses and the study of genetic relationships among them. In the present study, molecular analysis of HLA-A, -B, -C, -DQA1, -DQB1, and -DRB1 genes has been used to assign HLA allele and haplotype frequencies in 100 unrelated healthy individuals from the Baloch ethnic group of Iran. The results were compared with Baloch and other ethnic groups in the neighboring Pakistan. The results of this study showed that the most frequent HLA class I alleles were A*02011 (20.2%), B*4006 (11.1%), and C*04011 (28.6%). The most common HLA class II alleles were DQA1*0101/2 (42.5%), DQB1*0201 (32%), and DRB1*0301 (29%). Three-locus haplotype analysis revealed that A*11011-B*4006-C*15021 (5.8%) and DQA1*0501-DQB1*0201-DRB1*0301 (22.1%) were the most common HLA class I and II haplotypes, respectively, in this population. Neighbor-joining tree based on DA genetic distances and correspondence analysis according to HLA-A, -B, -DQB1, and -DRB1 allele frequencies showed that Baloch of Iran are genetically very close to Baloch and Brahui of Pakistan. This may reflect an admixture of Brahui and Baloch ethnic groups of Pakistan in the Balochistan province of Iran.

Hepatitis C virus (HCV) genotypes and chronic liver disease in Pakistan.

UNLABELLED: Hepatitis C virus (HCV) is classified into different types depending on nucleotide sequence variability. Detailed information on the distribution of various HCV genotypes in some geographical areas is available but little is known about Pakistan. In this study, a 5' non-coding region (NCR)-based restriction fragment length polymorphism (RFLP) genotyping assay was used to investigate the genotype distribution in a large series of HCV-infected patients in Karachi, Pakistan. Serum samples from 74 hepatitis B surface antigen (HBsAg)-negative patients with a clinical diagnosis of chronic liver disease (60 patients) and hepatocellular carcinoma (HCC) (14 patients) were assayed for anti-HCV antibody by second generation enzyme immunoassay and 48 were confirmed anti-HCV-positive (33 males, 15 females). Other causes of chronic liver disease (e.g. haemochromatosis, Wilson's disease and immune-mediated injury) were ruled out. Liver biopsy was done in 27/48 anti-HCV-positive patients and in all HCC patients. Genotypes were determined for 45/48 anti-HCV-positive study patients; 39/45 (87%) were type 3; four (9%) were type 1; one was type 2; and one was type 5. Past blood transfusion was the main identifiable risk factor found in 10 patients, all type 3. Seven of the 14 HCC patients were anti-HCV positive, (six were type 3). Most patients with hepatitis C presented with established cirrhosis and complications of portal hypertension and liver failure. IN CONCLUSION: (i) genotype 3 is the most common isolate in HCV-associated chronic liver disease in Pakistan; (ii) a significant proportion of HBsAg-negative cirrhotics are non-B, non-C in aetiology; and (iii) half of the patients with HCC have serological evidence of HCV infection.

Introduction and development of NCP using ICNP in Pakistan.

BACKGROUND: Traditionally, nursing care has been described as performing nursing tasks and often focused on nurses carrying out doctors' orders. In many countries of the world, including Pakistan, nurses do not document care in a standardized manner. Because of this limitation many health administrators, policy makers, and consumers make inadequate assumptions about nursing work, often regarding nurses as any other 'health care technician' who can be easily replaced by more economical health care workers. PURPOSE: To overcome this problem, standardized documentation is being introduced into the Aga Khan University School of Nursing and hospital, Aga Khan Health Services, Public Health School in Karachi, and government colleges of nursing, using the International Classification for Nursing Practice (ICNP). The purpose of this paper is to highlight the process of introducing and developing standardized nursing care plans (NCP) using ICNP in Pakistan. PROCESS: The process for introducing ICNP consists of four components, including administrative planning, development, teaching and training, and testing. Subsets of the ICNP for (i) maternity: antenatal, postnatal and natal care; and (ii) cardiology were developed using standardized NCPs. The subsets were developed by nurse experts and introduced at the testing sites. The testing will be conducted as a pilot project. Findings from the pilot will be used to continue and expand standardized nursing documentation using the ICNP across Pakistan. CONCLUSION: Through this project, nurses, midwives and lady health visitors (midwives, vaccinator and health educators) will test standardization of documentation and begin to evaluate efficiency and effectiveness of clinical practice.

Epilepsy in Pakistan: stigma and psychosocial problems. A population-based epidemiologic study.

PURPOSE: To assess the stigmatization and psychosocial problems of persons with epilepsy in Pakistan. METHODS: A population-based, cross-sectional epidemiologic study of 241 persons with epilepsy identified from an at-risk population of 24,130 individuals (64.7% from urban and 35.3% from rural areas). Of these patients, 77% suffered from recurrent non-febrile generalized convulsions. We evaluated degree of stigmatizations (i.e., avoidance by friends, neighbors, and others), and the effect of epilepsy on other psychosocial aspects (e.g., marriage), and also the relationships between gender and level of education of the patients, and stigmatization. RESULTS: Patients with epilepsy in Pakistan do not appear to be highly stigmatized, but their education and grades are affected by the disorder. They have difficulty performing activities of daily living and find it hard to make decisions about whether to marry or to have children. Women believed that they were more dangerous to others, received less help from their families, and, more frequently than men, encouraged others to avoid them. Women were also more likely than men to express the belief that people with epilepsy should not marry, but in fact, women more frequently married as compared men-a fact influenced by social and cultural pressures, including pressure from family, because it is nearly always the responsibility of the parents to arrange the marriage of a daughter. Influence of education indicates that people with epilepsy who have higher education, as compared with those with less education, had fewer children, were less often avoided by their classmates and neighbors, had fewer problems with plans for education, less frequently encouraged others to avoid them, were more frequently married, and believed that they were more dangerous to others. Most people believed that their conditions had a physical basis; only 3.1% attributed their epilepsy to supernatural causes. CONCLUSIONS: Stigmatization regarding epilepsy has not been proven to be an important feature in the culture of Pakistan because none of the observations are statistically significant as per P-value.

Parasuicide in Pakistan: experience at a university hospital.

There have been few reports of parasuicide from Pakistan, where the act is considered to be a criminal offence and the Islamic religion strongly disapproves of it. In order to address the problem, a retrospective case report analysis of all index cases of parasuicide presenting over a period of 3.5 years to a university hospital in Karachi, Pakistan, was undertaken. Our results showed that most of the subjects were young adults, with married women representing the single largest group. Self-poisoning with medication was the most common method, and benzodiazepines the most frequently used drug. Interpersonal conflict with the opposite sex was the most common precipitating cause. In Pakistani culture, marriage appears to be a significant source of stress for women. Reports based on official police records do not reflect the true picture of the problem in Pakistan.

Risk factors, prevalence, and treatment of anxiety and depressive disorders in Pakistan: systematic review.

OBJECTIVES: To assess the available evidence on the prevalence, aetiology, treatment, and prevention of anxiety and depressive disorders in Pakistan. DESIGN: Systematic review of published literature. STUDIES REVIEWED: 20 studies, of which 17 gave prevalence estimates and 11 discussed risk factors. MAIN OUTCOME MEASURES: Prevalence of anxiety and depressive disorders, risk factors, effects of treatment. RESULTS: Factors positively associated with anxiety and depressive disorders were female sex, middle age, low level of education, financial difficulty, being a housewife, and relationship problems. Arguments with husbands and relational problems with in-laws were positively associated in 3/11 studies. Those who had close confiding relationships were less likely to have anxiety and depressive disorders. Mean overall prevalence of anxiety and depressive disorders in the community population was 34% (range 29-66% for women and 10-33% for men). There were no rigorously controlled trials of treatments for these disorders. CONCLUSIONS: Available evidence suggests a major social cause for anxiety and depressive disorders in Pakistan. This evidence is limited because of methodological problems, so caution must be exercised in generalising this to the whole of the population of Pakistan.

Motor vehicle crashes in Pakistan: the emerging epidemic.

SETTING: Motor vehicle injuries are increasingly being recognized as a growing public health issue in the developing world. Pakistan is a developing country in South Asia where motor vehicle use has increased since independence in 1947. OBJECTIVE: This paper explores the magnitude and impact of injuries from motor vehicle crashes in Pakistan. METHODS: An exhaustive review of published and gray literature, together with a detailed analysis of government data from 1956. RESULTS: The data indicate a persistent increase in the numbers of motor vehicle crashes, injuries, and fatalities. Changes in the reporting of rates are important to note in evaluating the data. Commercial vehicles contribute disproportionately to these motor vehicle injuries. CONCLUSIONS: There is a need to further the recognition of injuries as a public health issue in this country. Specific exploration of the epidemiological data; intersectoral collaboration between health, law, police and transport; and the development of appropriate information systems, will contribute to an appropriate response by Pakistan.

Sibling orders of schizophrenic patients in Austria and Pakistan.

The influence of siblings on the socialization of the individual has been recognized as a fact by both psychology and sociology. The significance of sibling order for the outbreak of psychiatric diseases on the other hand is still discussed controversially. In our study, we compared the expected values and the positions actually found in the sibling order of 379 (233 males, 146 females) Austrian and 144 (101 males, 43 females) Pakistani patients diagnosed with schizophrenia according to DSM-IV (295). The position in the sibling order had no influence on the outbreak of schizophrenia in Austria; with Austrian schizophrenics, the results found were very near to the expected values. In Pakistan on the other hand, the eldest brothers from families with 2-4 siblings had a significantly higher risk of falling ill. The investigation of the composition of the sibships of schizophrenic patients also showed a high overrepresentation of men in the firstborn position in Pakistan. These facts seem to exercise influences that may either protect against the outbreak or encourage it. The differences found agree well with the fact that in Pakistan, both the gender of a child and the position in the sibling order entail different ways of treatment and different scopes of responsibility. Socialization in Austria on the other hand, at least in the recent decades, has become very uniform for both sexes, regardless of the sibling position.

Epidemiology and clinical profile of HIV/AIDS in Pakistan.

This study reviews available data on HIV/AIDS in Pakistan and is the first to analyse a clinical series of HIV-infected patients thus giving a wider perspective of the epidemic in Pakistan. A retrospective analysis of all medical records of patients with HIV/AIDS since 1986 was conducted in March 1998 at a Karachi hospital. There were 67 patients. Twenty-two were overseas (Middle East) contract workers. None were sex workers or drug users. Fifty-four had travelled or lived abroad. High risk sexual behaviour was reported in 35 patients of whom 26 men reported contact with commercial sex workers, mostly in the Middle East (21). The most common AIDS indicator condition was chronic diarrhoea. HIV in Pakistan is currently a disease of those Pakistanis (and their sexual partners) who have travelled abroad, overseas contract workers and those who, prior to 1989, were transfused abroad or received imported blood products.

Knowledge of modifiable risk factors of heart disease among patients with acute myocardial infarction in Karachi, Pakistan: a cross sectional study.

BACKGROUND: Knowledge is an important pre-requisite for implementing both primary as well as secondary preventive strategies for cardiovascular disease (CVD). There are no estimates of the level of knowledge of risk factor of heart disease in patients with CVD. We estimated the level of knowledge of modifiable risk factors and determined the factors associated with good level of knowledge among patients presenting with their first acute myocardial infarction (AMI) in a tertiary care hospital in Karachi, Pakistan. METHODS: A hospital based cross-sectional study was conducted at the National Institute of Cardiovascular Disease, a major tertiary care hospital in Karachi Pakistan. Patients admitted with their first AMI were eligible to participate. Standard questionnaire was used to interview 720 subjects. Knowledge of four modifiable risk factors of heart disease: fatty food consumption, smoking, obesity and exercise were assessed. The participants knowing three out of four risk factors were regarded as having a good level of knowledge. A multiple logistic regression model was constructed to identify the determinants of good level of knowledge. RESULTS: The mean age (SD) was 54 (11.66) years. A mere 42% of our study population had a good level of knowledge. In multiple logistic regression analysis, independent predictors of "good" level of knowledge were (odds ratio [95% confidence interval]) more than ten years of schooling were 2.5 [1.30, 4.80] (verses no schooling at all) and nuclear family system (verses extended family system) 2.54 [1.65, 3.89]. In addition, Sindhi ethnicity OR [3.03], higher level of exercise OR [2.76] and non user of tobacco OR [2.53] were also predictors of good level of knowledge. CONCLUSION: Our findings highlight the lack of good level of knowledge of modifiable risk factors for heart disease among subjects admitted with AMI in Pakistan. There is urgent need for aggressive and targeted educational strategies in the Pakistani population.

HIV-1 subtype A infection in a community of intravenous drug users in Pakistan.

BACKGROUND: Data on the subtypes of HIV in a population help in predicting the potential foci of epidemic, tracking the routes of infection and following the patterns of the virus' genetic divergence. Globally, the most prevalent HIV infection is the HIV-1 subtype C. In Asia, predominant subtypes of HIV-1 are B, C, and CRF-01AE. During the last few years, HIV prevalence in Pakistan has taken the form of a concentrated epidemic in at least two high risk groups, namely, Intravenous Drug Users (IDUs) and Male Sex Workers (MSWs). Factors that have facilitated the proliferation of HIV infection include transmission through a large number of repatriates and needle-sharing intravenous drug users, unscreened blood transfusions, and sexual illiteracy. The HIV subtypes infecting Pakistani populations have not been explored to date. In this study, we analyzed HIV-1 subtypes from in a high-risk community of IDUs in Karachi, the largest city of Pakistan. METHODS: Samples were collected from 34 IDUs after their informed consent. In addition, the study subjects were administered a questionnaire regarding their sexual behavior and travel history. For HIV analysis, DNA was extracted from the samples and analyzed for HIV types and subtypes using subtype-specific primers in a nested polymerase chain reaction (PCR). The results from this PCR were further confirmed using the Heteroduplex Mobility Assay (HMA). RESULTS: We found HIV-1 subtype A in all the 34 samples analyzed. A few of the study subjects were found to have a history of travel and stay in the United Arab Emirates. The same subjects also admitted to having contact with commercial sex workers during their stay abroad. CONCLUSION: Our study therefore shows clade A HIV-1 to be prevalent among the IDUs in Karachi. As the prevalence of HIV in Pakistan continues to rise, more work needs to be done to track the infection, and to analyze the strains of HIV spreading through the country.

Cardiovascular health knowledge and behavior in patient attendants at four tertiary care hospitals in Pakistan--a cause for concern.

BACKGROUND: Knowledge about coronary heart disease (CHD) and its risk factors is an important pre-requisite for an individual to implement behavioral changes leading towards CHD prevention. There is scant data on the status of knowledge about CHD in the general population of Pakistan. The objective of this study was to assess knowledge of CHD in a broad Pakistani population and identify the factors associated with knowledge. METHODS: Cross sectional study was carried out at four tertiary care hospitals in Pakistan using convenience sampling. Standard questionnaire was used to interview 792 patient attendants (persons accompanying patients). Knowledge was computed as a continuous variable based on correct answers to fifteen questions. Multivariable linear regression was conducted to determine the factors independently associated with knowledge. RESULTS: The mean age was 38.1 (+/- 13) years. 27.1% had received no formal education. The median knowledge score was 3.0 out of a possible maximum of 15. Only 14% were able to correctly describe CHD as a condition involving limitation in blood flow to the heart. Majority of respondents could identify only up to two risk factors for CHD. Most commonly identified risk factors were stress (43.4%), dietary fat (39.1%), smoking (31.9%) and lack of exercise (17.4%). About 20% were not able to identify even a single risk factor for CHD. Factors significantly associated with knowledge included age (p = 0.023), income (p < 0.001), education level (p < 0.001), residence (p < 0.001), a family history of CHD (p < 0.001) and a past history of diabetes (p = 0.004). Preventive practices were significantly lacking; 35%, 65.3% and 84.6% had never undergone assessment of blood pressure, glucose or cholesterol respectively. Only a minority felt that they would modify their diet, stop smoking or start exercising if a family member was to develop CHD. CONCLUSION: This is the first study assessing the state of CHD knowledge in a relatively diverse non-patient population in Pakistan. There are striking gaps in knowledge about CHD, its risk factors and symptoms. These translate to inadequate preventive behavior patterns. Educational programs are urgently required to improve the level of understanding of CHD in the Pakistani population.

High-risk sexual behaviours among drug users in Pakistan: implications for prevention of STDs and HIV/AIDS.

Our objective was to describe HIV/STD risk behaviours and awareness among a community-based sample of drug users in Pakistan. Drug users contacted through street outreach by a non-governmental organization in Quetta, Peshawar and Rawalpindi underwent interviewer-administered questionnaires. Descriptive statistics were used to characterize sexual behaviours by city, marital status and the use of injection drugs. Logistic regression was used to identify correlates of ever having an STD. Of 608 drug users studied, all but one was male; median age was 32 years and 45% had no formal education. Half were married, of whom 25% were living with their wives. Sexual behaviours were reported as follows: 14% had sex with other males, 28% reported sex with both males and females, 49% had paid money to have sex and only 10% had ever used condoms. One-fifth reported having had an STD and about 40% reported having suffered from either one or more STD-related symptoms. Only 41% had heard about HIV/AIDS, of whom 17% knew that HIV/AIDS could be transmitted through sexual contact. In conclusion, high-risk sexual behaviours are prevalent among male drug users in Pakistan, and awareness of transmission risks is low. These data attest to the urgent need for effective and specific interventions in Pakistan to prevent transmission of HIV and STDs among drug users and their sex partners.

Emergence of quinolone-resistant Neisseria gonorrhoeae in Pakistan.

Quinolone-resistant Neisseria gonorrhoeae (QRNG) have not been reported from Pakistan to date. This is the first report of the presence of QRNG in Pakistan. The study was performed at a tertiary care hospital laboratory in Karachi, Pakistan. Antimicrobial susceptibility data on all N. gonorrhoeae isolated between 1992 and 2002 were retrieved and analysed. Minimum inhibitory concentrations (MICs) of QRNG isolated in year 2002 were performed, and clinical information was collected. QRNG was first noted in 1999 and its proportion increased to 42% in 2002. MICs of the 12 isolates tested in 2002 showed a high level of resistance to ofloxacin with MIC of more than 4 microg/mL. Clinical information from patients with QRNG showed treatment failure. Emergence of QRNG in developing countries is alarming as there is no proper surveillance of increase in resistance. We strongly urge the need of detection and documentation of the resistant gonococcal isolates, as in vitro resistance is associated with clinical failure.
