The mechanisms that lead to the production of sensory hair cells during regeneration have been investigated by using 2 different procedures to ablate preexisting hair cells in individual neuromast sensory epithelia of the lateral line in the tails of salamanders, then monitoring the responses of surviving cells. In one series of experiments, fluorescent excitation was used to cause the phototox...
SIR,-Following the recent report by Drs P J Toghill and R G Wilcox (28 February, p 502) we would like to recount a similar case in this hospital The patient was a 54-year-old housewife who developed aplastic anaemia of undetermined aetiology. As in the case reported, she had been using a new hair dye prior to this. This contained para-toluene diamine sulphate. She showed no response to predniso...

Encapsulation of chemicals in liposomes and microneedling are currently used techniques to enhance the penetration of several substances through skin and hair. In this study, we apply a liposomal melanin-fluorescein compound to an ex vivo model of human skin, using a new electrical microneedling device (Nanopore turbo roller). The product was applied by hand massage (A) or with the assistance o...
Hair cells of the lateral line system in fish may differ in their susceptibility to damage by aminoglycoside antibiotics. Gentamicin has been reported to damage hair cells within canal neuromasts, but not those within superficial neuromasts. This finding, based on SEM imaging, indicates a distinction in the physiology of hair cells between the two classes of neuromast. Studies concerned with th...
A 22-year-old female presented to us after consuming hair dye with features of angio-neurotic edema, asphyxia and irregular pulse. Serial ECGs revealed presence of ST segment elevation and T wave inversion in anterior chest leads. Strongly positive c-troponin-T test further confirmed the myocardial damage. This is a rare manifestation of para-phenylene diamine poisoning mentioned in literature....
A 54-year old female with no history of atopy or previous dermatitis, working as an assistant nurse at the department of cardiology since many years, was referred to the department of occupational dermatology. The reason for referral was relapsing dermatitis with carbuncles progressing over a period of 3 years. Since the first episode the patient had had relapses of carbuncles on the ears, shin...
Despite considerable research, the issue of hair dyes and bladder cancer is still open to discussion. In January 2013, we searched in PubMed/EMBASE to identify observational studies investigating the association between personal use of hair dyes and bladder cancer incidence/mortality. Pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) were calculated using random-effec...
