A house-to-house, cross-sectional, population study of epilepsy on 24,130 individuals of all ages from southern Pakistan indicates an age-specific prevalence rate of 9.99 in 1,000 (14.8 in 1,000 in rural and 7.4 in 1,000 in urban areas) for recurrent, nonfebrile "active" epilepsy in Pakistan. Mean onset of epilepsy was 13.3 years, and 74.3% epileptic persons were aged < 19 years at onset of the disorder. The most common seizure type was tonicclonic in 77% [primary generalized tonic-clonic (GTC) in 59% and secondarily generalized in 18%], simple partial (SPS) in 5%, complex partial (CPS) in 6%, generalized absence in 1%, tonic in 3%, and myoclonic in 3% cases. Multiple seizures types in the same person were evident in 9.6% of only the generalized group. A putative cause could be suggested in 38.4% of cases: 32% had a positive family history of epilepsy, most common among siblings. Common perceived precipitants included fever in 29.2% and emotional disturbances in 16.6%. Only 3% of epileptic persons believed that their illness was due to super-natural causes. Treatment status was very poor, with only 2% rural and 27% urban epileptic persons receiving antiepileptic drugs (AEDs) at the time of the survey. We discuss the logistic and management problems of population-based epidemiologic studies in developing countries.

Summary: Purpose: To determine comparative prevalence rates, demographics, phenomenology, seizure classification, presumptive etiology, treatment status, and selected socioanthropological aspects of epilepsy in Pakistan and Turkey.

Summary: 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.

The synthesis and transportation proteins of the Vi capsular polysaccharide of Salmonella enterica serovar Typhi (serovar Typhi) are encoded by the viaB operon, which resides on a 134-kb pathogenicity island known as SPI-7. In recent years, Vi-negative strains of serovar Typhi have been reported in regions where typhoid fever is endemic. However, because Vi negativity can arise during in vitro passage, the clinical significance of Vi-negative serovar Typhi is not clear. To investigate the loss of Vi expression at the genetic level, 60 stored strains of serovar Typhi from the Faisalabad region of Pakistan were analyzed by PCR for the presence of SPI-7 and two genes essential for Vi production: tviA and tviB. Nine of the sixty strains analyzed (15%) tested negative for both tviA and tviB; only two of these strains lacked SPI-7. In order to investigate whether this phenomenon occurred in vivo, blood samples from patients with the clinical symptoms of typhoid fever were also investigated. Of 48 blood samples tested, 42 tested positive by fliC PCR for serovar Typhi; 4 of these were negative for tviA and tviB. Three of these samples tested positive for SPI-7. These results demonstrate that viaB-negative, SPI-7-positive serovar Typhi is naturally occurring and can be detected by PCR in the peripheral blood of typhoid patients in this region. The method described here can be used to monitor the incidence of Vi-negative serovar Typhi in regions where the Vi vaccine is used.

In this population with a normal cervical cytology, the prevalence of high-risk HPV types was very low. The major prevalent HPV genotype in Punjab Province of Pakistan was the low-risk HPV type 6, followed by HPV type 55. Sequencing of the partial L1 region suggested that the region was highly conserved in all reported sequences. This study highlights the need to conduct robust epidemiological studies in the region and to develop regular HPV screening so that the situation does not reach an alarming stage resulting in cervical cancer.
