Evaluation of Knowledge, Disease Severity and Quality of Life of Patients with Psoriasis

Background@#Psoriasis vulgaris is a chronic immune-mediated inflammatory multi-system disease characterised by keratinocyte hyperproliferation. Data regarding patients’ disease severity, knowledge and quality of life (QOL) is important to optimize treatment strategies for psoriasis. This study aims to evaluate and investigate the relationship between disease severity, knowledge and QOL of patients with psoriasis. @*Methods@#A cross-sectional multicentre study utilizing a socio-demographic data collection form, Psoriasis Knowledge Assessment Questionnaire (PKAQ), Dermatology Life Quality Index (DLQI) and Psoriasis Area and Severity Index (PASI was conducted. Correlations between PKAQ, DLQI and PASI were analysed using Spearman’s test. @*Results@#A total of 114 subjects participated in this study. Majority of them had mild psoriasis (n=73, 64%) based on PASI. The mean score of PKAQ was fourteen out of a total possible score of twenty-five, whereas the DLQI had a non-parametric distribution with a median (interquartile range) of 7 (10). Most subjects (32.5%) stated that psoriasis had a ‘moderate effect’ on their QOL, while only 3.5% said that it had an ‘extremely large effect’ on their QOL. There was a statistically significant correlation between PASI and DLQI (rs = 0.264, p = 0.004), with higher PASI scores corresponding to higher DLQI scores. No statistically significant correlation was found between DLQI and PKAQ (rs = -0.048, p= 0.612), and between PASI and PKAQ (rs = 0.058, p= 0.542).@*Conclusion@#Impairment of QOL was positively associated with severity of psoriasis. However, there was no significant relationship between knowledge and quality of life, as well as between knowledge and psoriasis severity.

Ethnopharmacological treatment of Cough in Piran, Malakand, Pakistan / Tratamiento etnofarmacológico de la tos en Piran, Malakand, Pakistán

The current study was designed to investigate the traditional recipes used to treat cough in Tehsil Piran, Malakand, Pakistan. These recipes were explored and quantitively analyzed for the first time. A total of 30 species of the plants, 6 animal products and one salt were reported to be used by the community to treat cough. Punica granatum L. and Olea ferruginea Royle dominated with Use value (UV) of 0.84 and Origanum vulgare L. with least use value of 0.1. The frequency citation (FC) of the Papaver somniferum L. is higher (98) while the lowest one is Verbascum thapsus L. (0.13). The large number of traditional recipes used for cough in this area shows that primary health care is still amalgamated in this culture. In future studies, these recipes may be further exploited as a base for modern medicine.

Cypermethrin-induced Repeated-dose Immuno-toxicity in Oryctolagus Cuniculus: An Investigation into Pathology of Spleen and Blood

Background: Cypermethrin is a pyrethroid insecticide widely used in agriculture and medicines. Its toxicity effects on spleen and blood in male and female rabbits is studied in this research. Methods: Age- and weight-matched does/females (n=24) and bucks/males (n=24) of Japanese White rabbits were subjected to intraperitoneal cypermethrin administration @50, 100 and 150 mg.kg-1 b.wt. in groups B, C and D, respectively.  The experimental rabbit does and bucks were tested for hematology alterations after each of 5 CY-treatments, at days 1, 8, 15, 22 and 29.  One rabbit doe and one rabbit buck were sacrificed fortnightly (days 15, 29, 43, 57 and 71) to obtain spleen for histological studies. Results: CY-treated rabbit bucks developed anemia, leukopenia, neutropenia, monocytosis, eosinophilia and basocytopenia mostly in dose and time dependent manner.  In contrast, rabbit does show transient but significant leukocytosis, neutropenia, lymphopenia, monocytosis, eosinophilia and basophilia only in high dose group.  Moreover, spleen histology revealed congestion, depletion of white pulp with increased red pulp and hemosiderin deposition in CY treated rabbit bucks, but not rabbit does. Conclusions: This study concludes that immuno-toxicity by cypermethrin insecticide is not similar in male and female subjects.

Marker Assisted Molecular Investigation of Kappa-Casein Gene in Bos Indicus Sindhi Genetic Group Using HINFI Restriction Enzyme

Background: Present research aimed to determine molecular genotype of kappa-casein gene in female Red Sindhi cattle. This gene has great influence on the technologically advanced milk properties. Methods: Blood specimens (n=50) from females of this cattle breed at a well-managed farm in Sindh-Pakistan were collected and commercial kit was employed for DNA extraction. Genotype determination of κ-casein gene and alleles was done through PCR-RFLP technique by using primer; PCR products were digested upon HINFI restriction enzyme. The digested fragments were analyzed by electrophoresis on agarose gel using ethidium bromide to increase visibility. The bands were examined under ultra violet-light to study polymorphic locus on DNA fragments. Results: Digestion upon HINFI restriction enzyme of 350bp fragment indicated three patterns. The 1st (homozygote genotype BB), 2nd (homozygote genotype AA) and 3rd (heterozygote genotype AB) patterns yielded major fragment(s) of 1) 266bp, 2) 134bp and 132bp and 3) 134bp, 132bp and 266bp, respectively. Each of the three patterns yielded one minor fragment of 84bp. The genotype frequency for homozygote AA and the allelic frequency of allele A were higher than the same for homozygote genotype BB and the allelic frequency of allele B, respectively. Conclusions: An accurate profile of genetic make-up and alternate forms of κ-casein genes in Sindhi cattle is likely to help researchers, policy makers, immunologists, dietitians, neonatologists, community physicians and managerial as well as production level officials to exploit it to full potential.

Insecticidal Exposure may be the Cause of Progression of Immune Disorders and Inflammatory Diseases through Dys-regulation of Cytokines

Industrial revolution has dangerously increased the load of environmental or environmentally induced diseases. Recently, the insecticides (a class of pesticides killing various insects) have become one of the most important environmental pollutants. This Review discusses the association of insecticides, cytokines dys-regulation and the development of immuno-regulatory disorders and chronic inflammatory conditions. In spite of abundant reviewing and reporting of various immuno-inflammatory diseases individually, efforts lack to understand the central pathological mechanism underlying these diseases collectively. The cytokines are extensively involved in inter-cellular communications; they are regarded attractive markers for risk stratification or patient prognosis. In this Review, an understanding has been generated about the role of various receptors, genes and signaling pathways etc. in the trianglular link of cytokines, immuno-inflammatory diseases and insecticides. Such role, in a number of instances, had been those of (1) a receptor tyrosine kinase designated as c-kit or SCF receptor and (2) NFκB, the most excellently described transcription factor. The conclusion of the Review is that insecticides are linked with increasing susceptibility to various diseases especially any type of chronic inflammation through cytokine dys-regulation. Moreover, insecticidal toxicity can cause deviations in certain parameters of diagnosis. So insecticide applicators must be stressed to ensure only recommended doses and formulations of insecticides if really necessary.
