Premature Greying of Hair (Premature Canities): A Concern for Parent and Child

Journal of Pigmentary Disorders (2017)

PK Nigam P. K. Nigam

Hair goes grey with chronological aging. Premature hair greying may have significant adverse effects on the appearance, self-esteem, and socio-cultural acceptance of the affected individual. The exact aetiopathogenetic mechanism causing premature greying is still not clear and much speculative. Premature canities may appear alone as an autosomal dominant trait or it may occur in association with certain other disorders. The genes Pax3 and MITE play an important role in melanocyte stem cell maintenance and differentiation. Defective melanosomal transfer to the cortical keratinocytes or melanin incontinence due to melanocyte degeneration is also believed to contribute to greying. Despite the extensive molecular research being carried out to understand the pathogenesis of canities, treatment options still remain far from satisfactory and no effective therapy is available. Premature greying is a feature in a number of well recognised syndromes. A number of other conditions have also been observed to be associated with premature greying of hair.

Relation between psoriasis and psoriatic arthritis: A study of 40 patients

National Journal of Clinical Orthopaedics (2018)

Hardik Sethi P. K. Nigam

Introduction: Psoriasis is a chronic, immune-mediated, systemic disorder with a worldwide prevalence of 0.9–8.5%. Psoriatic arthritis is a seronegative, chronic, inflammatory arthropathy often associated with psoriasis. Objective: To study the relation between Psoriasis and Psoriatic Arthritis. Methodology: Study Area: New Civil Hospital Surat. Sample Size: 40. Results: Out of 40 patients there were 25 males (62.5%) and 15 females (37.5%). Arthropathic changes in males were found in 8 (20%) cases and in 4 (10%) cases in females. Conclusion: It is concluded from the above study that nearly 30 % of patients having Psoriasis also suffer from Psoriatic Arthritis associated with different joint involvement of hands, feet, Sacroiliac Joints, Knee, Cervical spine and Hip joints.

Genetic Analysis of Resistance to Linseed Wilt

Indian Journal of Genetics and Plant Breeding (The) (1988)

S. C. Goray H. K. Khosla Y. M. Upadhyaya P. K. Nigam S. L. Naik

Six Unseed (Linum usitatissimum Linn.) types, 3 resistant, R-5S2, R-556 and G-194, and 3 susceptible, IPI-6, R-17 and G-440, to wilt were subjected to a diallel crossing involving 15 crosses. Out of these, three crosses, IPI-6 × R-17, IPI-6 × G-440 and R-17 × G-440, were with both the susceptible parents; nine crosses, 1PM × R-552, IPM × R-556, IPI-6 × G-194, R-17 × R-552, R-17 × R-556, R-17 × G-194, G-440 × R-552, G-440 × R-556 and G-440 × G-194, involved a single resistant parent; and three crosses, Jt-552 × R-556, R-552 × G-194 and R-556 × G-194, with both resistant parents. Genes governing resistance were worked out by χ2 test. A monogenic, digenic and trigenic pattern of gene action was recorded for the resistance to linseed wilt (Fusarium oxysporium) in the crosses studied.
