Therapeutic injections in Pakistan: from the patients' perspective.

OBJECTIVE: To investigate the behaviour, knowledge of risks, and attitudes towards injections among patients at a clinic in Karachi. METHODS: In March 1995, trained staff administered a structured questionnaire to 198 consecutive new adult patients attending a university clinic in Karachi, Pakistan. RESULTS: Half (97:49%) of the patients received injections at their last visit to a health care provider. 3.5% had received 10 or more injections in the last year. 64% felt that injections were more powerful and were willing to pay more for them than for pills. 84% preferred pills or advice over injections if told they were equally effective, 83% believed that a used needle could transmit a fatal disease, and 86% believed that it is usually possible to get better without an injection. 91% reported that the doctor always recommends an injection; few patients (9%) ever asked for one. Injections were given without much regard for the chief complaint of the patient. Sonic needles (n = 21) for the injection came from bowls of water: of those from closed packets (n = 116), 68 were 'cleaned' by wiping ot placing them in water. 91% of patients (180) knew at least one risk of reuse of needles. Patients who knew three or more risks of using unclean needles were 0.14 times as likely to have had more than five injections per year in the last 5 years hut only if the patients had s or more years of education. CONCLUSION: Patients receive injections from doctors in Pakistan frequently, indiscriminately and often without proper safety precautions. They are aware of both positive and negative aspects of injections but are likely to do what the doctor suggests. Interventions to reduce risky overuse of injections should focus on patients' general education and knowledge of the risks of injections to empower them to choose healthier therapies.

Onychomycosis in Lahore, Pakistan.

BACKGROUND: Onychomycosis, a common nail disorder, is caused by yeasts, dermatophytes, and nondermatophyte molds. These fungi give rise to diverse clinical presentations. The present study aimed to isolate the causative pathogens and to determine the various clinical patterns of onychomycosis in the population in Lahore, Pakistan. PATIENTS: In 100 clinically suspected cases, the diagnosis was confirmed by mycologic culture. Different clinical patterns were noted and correlated with causative pathogens. RESULTS: Seventy-two women (mean age, 32.6 +/- 14.8 years) and 28 men (mean age, 40.6 +/- 15.8 years) were studied. Fingernails were involved in 50%, toenails in 23%, and both fingernails and toenails in 27% of patients. The various clinical types noted were distolateral subungual onychomycosis (47%), candidal onychomycosis (36%), total dystrophic onychomycosis (12%), superficial white onychomycosis (3%), and proximal subungual onychomycosis (2%). Candida was the most common pathogen (46%), followed by dermatophytes (43%) (Trichophyton rubrum (31%), T. violaceum (5%), T. mentagrophytes (4%), T. tonsurans (2%), and Epidermophyton floccosum (1%) and nondermatophyte molds (11%) (Fusarium (4%), Scopulariopsis brevicaulis (2%), Aspergillus (2%), Acremonium (1%), Scytalidium dimidiatum (1%), and Alternaria (1%). CONCLUSIONS: Onychomycosis is more common in women of 20-40 years of age. Distolateral subungual onychomycosis and candidal onychomycosis are the most common clinical presentations, and Candida and T. rubrum are the major pathogens in Pakistan.

Clinical and epidemiological observations of cutaneous tuberculosis in Larkana, Pakistan.

BACKGROUND: Cutaneous tuberculosis is widespread in Pakistan but has not been fully documented. This study was conducted to determine the clinical pattern, nature and existence of the disease in Larkana, Sindh province, Pakistan. METHODS: We are reporting 153 cases of patients with cutaneous tuberculosis who visited our department from 1996 to 1999. All cases were diagnosed at the clinic, and the biopsies were examined for histopathological evidence. The patients received three antituberculous treatments during a 9 month course. RESULTS: Clinically, 63 (41.2%) cases of lupus vulgaris, 54 (35.3%) of scrofuloderma, 29 (19.59%) of lupus verrucosa cutis, six (3.92%) of tuberculosis cutis orificialis and one (0.64%) case of disseminated cutaneous tuberculosis were observed in our department from 1996 to 1999. All patients were aged between 3 and 50 years and had experienced the present complaints for 1 to 12 years. Sixty-nine (45.1%) cases were children aged under 10 years, 50 cases (37.25%) were aged between 10 and 20 years, and 27 cases (17.65%) were aged over 20 years. There was no considerable ratio difference of the disease between male and female patients. Histopathologically, all the specimens showed chronic granulomatous changes; the majority was infiltrated with epitheloid cells, langhans giant cells, plasma cells and other inflammatory cells, such as lymphocytes, eosinophils and neutrophils in ulcerated lesions. Increased numbers of mast cells were seen in upper and lower dermis in two-thirds of the specimens. Caseating necrosis was visible in half of the specimens while Ziehl-Neelsen stain was negative in all the sections. CONCLUSIONS: The observed number of patients was moderately large, thus indicating a high incidence of cutaneous tuberculosis in Larkana. Lupus vulgaris, a form of cutaneous tuberculosis, was widespread in this area and prevalent in adults, while scrofuloderma was prevalent in children. Moreover, the existing rate of the disease was higher in children aged under 10 years and lower in adults. This indicates that children are more prone to this disease than adults.

Defining the cultural milieu for implementing faculty practice in Pakistan.

Faculty practice can promote a collaborative partnership mutually beneficial to both nursing education and service. However, little is known about its implementation in developing countries. The purpose of this study was to explore the potential for introducing faculty practice within the cultural milieu of Karachi, Pakistan. Focus groups of nursing faculty, staff and students were conducted in various settings: government, semigovernment and private institutions to elicit the data. Data analysis revealed that a more comprehensive definition of faculty practice is needed that will provide the foundation for a culturally acceptable model of faculty practice in Pakistan. Hierarchy dominates the current cultural milieu and must be addressed before faculty practice can be implemented.

Negotiating the informed-consent process in developing countries: a comparison of Swaziland and Pakistan.

Protecting the rights of research participants when conducting studies within an international context presents many challenges. The purpose of this article was to compare and contrast the process of obtaining informed consent in two very different countries - Swaziland and Pakistan. Major aspects of the informed-consent process presented included identification of gatekeepers, seeking permission from officials, negotiating with these officials and Institutional Review Board (IRB) committees in regard to the type of data to be collected, and explaining informed consent to participants in the field. Data for this article is based upon qualitative research of collaboration between nurses and healers in Swaziland and from a variety of studies completed in Pakistan. These studies demonstrate the inadequacy and complexity of applying western-based concepts of informed consent to developing countries.

Paraspiralatus sakeri n. g., n. sp. (Nematoda: Spiruroidea, Spirocercidae) from saker falcons, Falco cherrug in Saudi Arabia and the first report of larvae from the subcutaneous tissues of houbara bustards, Chlamydotis undulata macqueeni in Pakistan.

A new nematode genus and species, Paraspiralatus sakeri, is described from the stomach of a wild-caught, female saker falcon in Saudi Arabia. This spirurid differs from the nearest genus and species Spiralatus baeri Chabaud, Brygoo & Durette, 1963 in the shape of the pseudolabia, shape of the buccal capsule and absence of a large cephalic vesicle. In addition, third stage spirurid larvae were recovered for the first time from subcutaneous tissues of two houbara bustards. These had died in the Rahim Yar Khan Rehabilitation Center (Houbara Foundation International, Lahore, Pakistan) in Pakistan and were examined at the National Avian Research Center in the United Arab Emirates. The morphology of the larvae and host pathology are described. Comparative studies with the adult spirurids from the saker falcon showed each to have similar cephalic and pharyngeal morphological features to the adults described indicating they are probably the same species. Spirurid nematodes of the suborder Spirurina normally have an arthropod intermediate host. In view of the host, the site from which the larvae were recovered and the fact that this is a rare occurrence, the houbara bustard is considered to be a paratenic host.

Impact of health service provision on mothers and infants in a rural village in North West Frontier Province, Pakistan.

OBJECTIVE: The objective of this paper is to examine the impact of the Health Service Research Project of the Pakistan Medical Research Council (PMRC) on mothers and infants in Budhni village, North West Frontier Province (NWFP), Pakistan. METHODS: Information from the PMRC records on the socioeconomic and demographic situation over the last 10 years and anthropometric measurements made on all infants from 1986-96 were collected and analysed. RESULTS: The demographic data showed a number of changes, namely a reduction in birth rate and improvements in perinatal, neonatal, infant and child mortality rates. Literacy in the village was poor (27 and 39% literate in 1986 and 1996, respectively) and female literacy showed no improvement (14%). Improvements in sanitation and in the water supply introduced by the PMRC had limited success, as clean water was subsequently contaminated by unclean hands and utensils, and 50% of the population continued to use open fields for sanitation. In 1986 only 27% of children 0-5 years were vaccinated, but by 1996, 96% of children had completed polio, diphtheria/pertussis/tetanus (DPT) and bacille Calmette-Guérin (BCG) vaccination programmes and 95% of women of child-bearing age were vaccinated against tetanus. Protection against tetanus reduced neonatal deaths and from 1993 onwards there have been no further cases. Anthropometric data for the period 1986-96 for infants (0-24 months) showed that at birth the majority of infants were close to the 50th National Centre for Health Statistics (NCHS) centile for weight and length, and only 5% of birth-weights were less than 2.5 kg. Growth charts showed faltering in length and weight and by 24-months length in both boys and girls was below the 3rd NCHS centile and weights were just above. CONCLUSIONS: Reductions in child mortality have occurred over the period 1986-96. However, the slow progress in adopting hygienic practices, despite health education, and the low literacy rates, particularly in women, may hamper continued improvement.

Population dynamics of some Pakistan mosquitoes: the impact of residual organophosphate insecticide spray on anopheline relative abundance.

Two rounds of residual organophosphate house spray regionally eradicated susceptible endophilic resting anophelines (Anopheles culicifacies, An. stephensi and An. subpictus) from rural villages in Punjab province, Pakistan. Partially exophilic resting species (An. annularis and An. pulcherrimus) also were eliminated from resting within the village, but persisted in bovid bait collections throughout the spray period. The abundance of the partially exophilic resting species returned to prespray levels shortly after insecticide efficacy declined (five to six weeks post-spray), while repopulation of the villages by the endophilic resting species required from 12 to 26 months. Malathion resistance developed rapidly in An. stephensi and resulted in treatment failures two years after this compound was first used for anopheline control in Pakistan.

Patterns of health-care utilization and morbidity in a rural community near Lahore, Pakistan.

Patterns of health-care utilization and of morbidity were investigated in a demographically defined community: the 1400 inhabitants of a rural village near Lahore, Pakistan. The data collected, by semi-monthly clinic surveys from February 1982 to January 1983, showed that 42% of the study population sought health care during the year-long study period, between one and 10 (mean 2.1) times each. Females attended the clinics twice as often as males. The 1193 person-visits that were recorded at the field clinics yielded a total of 1354 cases of various diseases. The cumulative number of clinic-visits per person fitted a negative binomial distribution, indicating that health problems were concentrated in a small portion of the population. When the patients were classified according to the International Classification of Diseases, the most common disease category was that of the respiratory system (27.6%), followed by infectious and parasitic diseases (18.7%), diseases of the skin (13.7%) and those of the nervous system and sense organs (10.9%). Classification of the cases by single disease condition indicated that diarrhoea, helminthiasis, malaria, anaemia, conjunctivitis, bronchitis, coryza, pharyngitis, tonsillitis, dyspepsia and pyoderma were the most common diseases. In view of the fact that infectious diseases continue to be a major public health problem in rural Pakistan, the need for a sound health policy that is primarily focused on preventive medicine, especially health education, is apparent.

Insights from community-based research on child pneumonia in Pakistan.

Although pneumonia is a major cause of death in Pakistan, little is known about community beliefs and practices surrounding the disease. In this study, 35 mothers and four self-trained allopathic practitioners were interviewed in Karachi squatter settlements and rural Punjab. The findings indicate that maternal ideas about chest anatomy and the cause of pneumonia (principally "coldness") are very different from biomedical concepts. Further, mothers judge fast breathing impressionistically and tend to attribute it to fever alone. Nevertheless, they know that it is abnormal and most also link chest indrawing with pneumonia. Only mothers lacking other options take their children to government health facilities. Instead, most turn to private (frequently unlicensed) practitioners, although observation shows that such individuals are unable to diagnose pneumonia correctly and that they build their practices around the indiscriminate use of antibiotics. The study demonstrates that the target of ARI education in Pakistan should extend beyond government doctors to mothers and private practitioners as well.

The pioneers of rural Pakistan: the Lady Health Visitors.

Since 1978, when the World Health Organization and the United Nations International Children's Emergency Fund called for urgent action by all governments to provide appropriate health care for the underprivileged, the world community has attempted to implement primary health care strategies. Pakistan, with a population of 118 million people, is one of those countries where the rural population and the underprivileged groups in the katchi-abadis (squatter settlements) of the urban areas lack appropriate and accessible health services. This article highlights the community experiences of a remarkable group of young Muslim women, the Lady Health Visitors (LHVs) of the Aga Khan Health Services, who deliver primary health care services to disadvantaged women and children in the northern mountainous areas and rural villages of Pakistan. The LHVs are the first contact with the health care system that these underprivileged women experience. The LHVs cure, care, teach, and train traditional birth attendants. In addition, they perform health promotion and document their findings. To provide their maternal and child health services, the LHVs travel by foot through miles of rough terrain to settlements and villages. Prenatal and postnatal care, anemia, diarrhea, and malnutrition are among the major health care problems of these rural women and their children under 5 years of age.

Prevalence and causes of blindness and low vision in a rural setting in Pakistan.

PURPOSE: To determine the prevalence and causes of blindness and visual impairment in people 40 years of age and older in Budni, Peshawar, Pakistan. METHODS: A population-based cross-sectional study was carried out involving 1,106 men and women 40 years of age and older in a rural area in Pakistan's North West Frontier Province (NWFP). All subjects with a presenting visual acuity < 6/18 in either eye were referred to a centralized clinic for a standardized eye examination that included refraction and dilated fundal examination. The main outcome was blindness (presenting visual acuity < 3/60 in the better eye) and low vision (presenting VA < 6/18-3/60 in the better eye). RESULTS: Of 1,106 people examined, 21 (1.9%; 95% CI: 1.1-2.7%) were blind, while another 27 (2.4%) and 62 (5.5%) subjects had severe visual impairment (< 6/60-3/60) and visual impairment (< 6/18-6/60), respectively. Women, as compared to men, had a higher prevalence of visual impairment and severe visual impairment; but they had a lower prevalence of blindness (1.6 vs. 2.2%); however, the difference was not statistically significant (0.6%; 95% CI: -0.9-2.1%). Similarly farmers had the highest prevalence of blindness. The leading cause of blindness and low vision was cataract, which accounted for 14 of 21 (66.6%) cases of blindness and 49 of 89 (55.5%) cases of low vision. The second leading cause of blindness was uncorrected aphakia. CONCLUSION: Much of the blindness was due to unoperated cataract and uncorrected aphakia. Thus, there is an urgent need to develop ways in which cataract surgical output could be increased, and glasses provided to those who need them.

Glaucoma admissions and surgery in public sector tertiary care hospitals in pakistan: results of a national study.

PURPOSE: To assess the annual number of glaucoma operations and admissions in the public sector tertiary care hospitals in Pakistan. METHODS: Eye departments in all 18 public tertiary care centers in the country were requested to provide data on the number of glaucoma operations and admissions during 1998. Of these, 13 hospitals agreed to participate. Eye departments' log books or patients' records were used to collect data retrospectively on the total number of eye admissions, the total number of glaucoma admissions, the type of glaucoma, and the total number and type of glaucoma operations. RESULTS: Glaucoma accounted for 8.1% (1,942/23,931) of all eye admissions. Open-angle glaucoma was responsible for 37.6% or 731 glaucoma admissions followed by secondary glaucoma (35.0%) and angle-closure glaucoma (18.2%). During 1998, 1,407 glaucoma-related operations were performed in the selected hospitals. The mean (+/-SD) and the median number of operations performed were 108.2 (+/-59.6) and 112 (range: 17-206), respectively. Trabeculectomies accounted for 1,043 (74.1 %) of all procedures. Their number ranged from 16 to 170 (median: 84) in the selected hospitals. CONCLUSIONS: We believe that the annual number of glaucoma operations performed in the public tertiary care hospitals in Pakistan is far less than required. In-depth research is therefore needed to explain if this is because of gaps in service provision or a genuine shift to medical management of glaucoma on an outpatient basis.

Clinical and microbiological diagnosis of trachoma in children living in rural areas in the district of Attock, Punjab, Pakistan.

BACKGROUND: Trachoma is a sight-threatening process triggered by infection of the conjunctiva with Chlamydiae. When this infection becomes chronic and is associated with poverty it triggers trachoma, the prime cause of infectious blindness in the world. Since the 1958 report indicating that the highest incidence of trachoma in Pakistan was found in the province of Punjab, no new trials have been published. In the present study, we assessed the prevalence of trachoma in 3968 children living in 11 rural villages in the district of Attock, Punjab, Pakistan. The children with trachoma were sampled to detect C. trachomatis by PCR. METHODS: Children in rural villages in the district of Attock were examined for trachoma in February 2004. Samples were obtained by scraping, and DNA was extracted (MagnaPure-LC Robot) and amplified to detect C. trachomatis (Amplicor-Roche). The quality of sampling was assessed by quantifying the number of cells by real-time PCR. RESULTS: The prevalence of trachoma was 3.7% (0 to 6.2%). PCR was positive in 20% of samples from trachomatous children and the number of cells was always > 100/sample. The income levels, illiteracy, use of latrines, water supply, and the presence of animals close to dwellings were similar in all the villages. In Sujjenda, the prevalence was doubled in the warmest season. CONCLUSIONS: Trachoma was diagnosed in 3.7% of the children aged < 10 years. The low rates for positive PCR may be due to loss of the plasmid, the involvement of other Chlamydiae, or their absence in chronic infections. The results obtained here underestimate the prevalence of trachoma because most of the mothers (and babies) were not tested in the district of Attock.

Men and reproductive health in rural Pakistan: the case for increased male participation.

OBJECTIVES: In Pakistan, the role of men has always been considered to dominate in the decision-making process pertaining to women's fertility and birth spacing. This study was done to explore men's knowledge, perceptions and behavior on various reproductive health issues. METHODS: A cross-sectional survey was carried out among 180 married adult males in 12 rural districts of Pakistan in 2000. The study was qualitative, utilizing tools such as in-depth and key-informant interviews. RESULTS: The findings pointed out gaps in knowledge and misconceptions among men on a range of reproductive health issues and stress the need for health education. The findings suggest that strategies such as couple counseling, door-to-door campaigns by village-based male family planning workers and small group meetings could be effective. This study indicates a pressing need for incorporating effective intervention strategies, both at the community and the clinic level, backed with efficient counseling, motivation, and provision of services with appropriate education of males in rural areas. CONCLUSION: The findings suggest that investment into promotion of healthy fertility control practices among men will be effective in the near future, as they are interested in acquiring new knowledge and are willing to become partners.

Y-chromosomal DNA variation in Pakistan.

Eighteen binary polymorphisms and 16 multiallelic, short-tandem-repeat (STR) loci from the nonrecombining portion of the human Y chromosome were typed in 718 male subjects belonging to 12 ethnic groups of Pakistan. These identified 11 stable haplogroups and 503 combination binary marker/STR haplotypes. Haplogroup frequencies were generally similar to those in neighboring geographical areas, and the Pakistani populations speaking a language isolate (the Burushos), a Dravidian language (the Brahui), or a Sino-Tibetan language (the Balti) resembled the Indo-European-speaking majority. Nevertheless, median-joining networks of haplotypes revealed considerable substructuring of Y variation within Pakistan, with many populations showing distinct clusters of haplotypes. These patterns can be accounted for by a common pool of Y lineages, with substantial isolation between populations and drift in the smaller ones. Few comparative genetic or historical data are available for most populations, but the results can be compared with oral traditions about origins. The Y data support the well-established origin of the Parsis in Iran, the suggested descent of the Hazaras from Genghis Khan's army, and the origin of the Negroid Makrani in Africa, but do not support traditions of Tibetan, Syrian, Greek, or Jewish origins for other populations.

Postexposure treatment of rabies in Pakistan.

To evaluate compliance with current World Health Organization (WHO) guidelines for postexposure treatment (PET) of rabies, we interviewed all animal bite victims seeking treatment on the same day of each week from 28 December 1994 through 18 January 1995 at the Civil Hospital of Karachi (Pakistan), a major referral center. Of the 143 patients studied, 109 (76%) sustained bleeding transdermal bites (WHO category III). Overall, wounds were not washed with soap or an antiseptic in 69% of victims. All victims received 5% sheep brain-derived vaccine, and only three of the 109 victims with category III bites received rabies immune globulin. PET of rabies in Karachi was deficient by all WHO standards. Although there is a great urgency to improve PET, it will remain a costly and inefficient method of controlling rabies. Reduction of rabies reservoirs is required to decrease human deaths due to rabies in Pakistan and other developing countries in which canine rabies is endemic.

Antibiotic strategies for developing countries: experience with acute respiratory tract infections in Pakistan.

The Pakistan program for control of acute respiratory tract infections (ARIs) adopted the standard ARI-case-management strategy of the World Health Organization and recommended co-trimoxazole for the management of nonsevere pneumonia. Reports in that country of high in vitro antimicrobial resistance of Streptococcus pneumoniae and Haemophilus influenzae to co-trimoxazole prompted the program to reevaluate its treatment policy. Two community-based studies during 1991-1993 showed in vivo efficacy of co-trimoxazole in 92% and 91% of children with nonsevere pneumonia. A third double-blind trial showed co-trimoxazole and oral amoxicillin to be equally effective in vivo in cases of nonsevere pneumonia, despite high in vitro resistance. Country-wide surveillance from 1991 to 1994 revealed 78.3%-79.9% in vitro resistance to co-trimoxazole among S. pneumoniae isolates and 59.5%-61.0% among H. influenzae isolates. Co-trimoxazole is still recommended by the Pakistan ARI control program. The fact that amoxicillin is three times more expensive and must be administered more frequently is a big impediment to recommending it as a first-line drug for nonsevere pneumonia.
