Verruca vulgaris is a viral infection with high recurrence rates and is very difficult to treat. It occurs due to the ability of the virus to evade immune recognition. This immune evasion by the ...human papillomavirus (HPV) can be circumvented by injecting HPV antigens subcutaneously and inducing inflammation and a systemic immune response. Falkner technique is an approved technique for the treatment of warts. In this observational study, we analyzed the recovery rate among patients undergoing this technique as part of their routine treatment. The aim of this study is to study the clinical outcome of Falkner's needling technique that is being used for the treatment of verruca vulgaris.
Under local anaesthesia, only a single wart was vertically punctured using a 26-gauge needle up till the subcutis multiple times till bleeding was observed. No treatment was done for other warts. Patients were advised not to take any anti-inflammatory medications for pain and were observed for responses after 1 week as well as 1 and 3 months.
Of 41 patients included in this study, the total resolution of both the punctured and distant warts occurred in 28 patients (68.29%) and partial response in 7 patients (17.1%) by the end of 3 months. Interestingly, individual warts that were subjected to needling showed complete resolution in 35 patients (85.4%).
Falkner's needling method provides a high rate of complete resolution of multiple warts at both the needled and distant sites after a single treatment session of only a single lesion. This modality has a high cure rate, is easy to perform, requires minimal infrastructure support, is cost-effective, and can be undertaken at most peripheral settings with minimal training.
Purpose
– The purpose of this paper is to investigate a two dimensional problem in magneto-micropolar thermoelastic half-space with fractional order derivative in the presence of combined effects of ...hall current and rotation subjected to ramp-type heating.
Design/methodology/approach
– The fractional order theory of thermoelasticity with one relaxation time derived by Sherief et al. (2010) has been used to investigate the problem. Laplace and Fourier transform technique has been used to solve the resulting non-dimensional coupled field equations to obtain displacement, stress components and temperature distribution. A numerical inversion technique has been applied to obtain the solution in the physical domain.
Findings
– Numerical computed results of all the considered variables have been shown graphically to depict the combined effect of hall current and rotation. Some particular cases of interest are also deduced from the present study.
Originality/value
– Comparison are made in the presence and absence of hall current and rotation in a magneto-micropolar thermoelastic solid with fractional order derivative.
