Human papillomavirus infection in females with normal cervical cytology: Genotyping and phylogenetic analysis among women in Punjab, Pakistan.

Int J Infect Dis 2018 Jan 11;66:83-89. Epub 2017 Nov 11.

Sheikh Zayed Medical Hospital, Rahim Yar Khan, Pakistan.

Background: Globally, cervical cancer is the fourth most common cancer in women and the seventh most common cancer overall, accounting for an estimated 300 000 annual deaths. Human papillomavirus (HPV) is the second most common cause of cervical cancer worldwide. HPV screening is not a common practice in Pakistan. The aim of this study was to determine the prevalence of HPV and HPV types in women with a normal cytology of the cervix living in the upper and lower regions of Punjab, Pakistan, and to analyze the risk factors for HPV in this region.

Methods: PCR analysis was performed for 1011 female patients with a normal cytology of the cervix from various districts of Punjab Province, Pakistan. Risk factors for the acquisition of HPV were studied. High-risk HPV types (HPV16 and HPV18) were detected using the Abbott Real Time HR HPV test. To determine the genotype, partial L1 region sequences of HPV-positive samples were subjected to sequencing using MY/09/MY11 primers, and a phylogenetic tree was constructed using CLC software.

Results: The study found a 4.74% prevalence of HPV, with the most frequent HPV type found being the low-risk HPV6 (in 25% of infected individuals), followed by HPV55 (22.9%), HPV11 (20.8%), and high-risk types HPV45 (12.5%), HPV33 (8.33%), HPV18 (6.25%), and HPV16 (4.16%). Phylogenetic analysis of all HPV types in this study showed 80-99% nucleotide identity with types related to the same species. The sequences were clustered with China, India, Mexico, Iran, Slovenia, and Germany, showing the diversity in origin of the various genotypes prevalent in Pakistan.

Conclusions: 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.

The Croydon Assessment of Learning Study: prevalence and educational identification of mild mental retardation.

J Child Psychol Psychiatry 2006 Aug;47(8):828-39

Department of Child & Adolescent Psychiatry, King's College London, Institute of Psychiatry, London, UK.

Background: Mild mental retardation is an enduring and impairing condition. Its prevalence has varied widely across different studies from .5 to over 8%, with higher rates in completely ascertained samples. The current study estimates the prevalence of low IQ in the mental retardation range (intellectual disability) in a population sample and examines the factors that relate to educational identification.

Method: A total of 2,730 children in school years 8 and 9 attending local authority schools were assessed in school with the group-administered Cognitive Abilities Test (CAT). A sample of 304 pupils at high, moderate and low risk of mild mental retardation was selected for in-depth study. This included the individually measured full-scale IQ (WISC-III(UK)), the Wechsler Quicktest of attainments, the Strengths and Difficulties Questionnaire from parents and teachers and an abbreviated version of the Social Communication Questionnaire.

Results: Of those selected for the in-depth study, 204 (67%) participated, with a greater proportion from the low risk group. A range of prevalence estimates were calculated using different imputation methods and assumptions about individuals not screened. Rates of pupils with WISC IQ < 70 varied from 5.8% to 10.6%. There were no significant gender differences. In contrast to the high prevalence estimates using the WISC, the proportion of pupils scoring in the lowest stanine on the CAT was as expected. Only 15% of those with IQ < 70 had a statement of special educational needs or attended a school for moderate learning difficulties. Behaviour, particularly social communication problems, predicted educational identification.

Conclusions: The current study produced a high estimate of the prevalence of mild intellectual disability based on the WISC but not on the CAT. The findings highlight that the majority of mild intellectual disability in the UK would not be detected using registers. Cases that are detected by registers are more behaviourally disturbed than others.
