Comparative study of the efficacy and safety of two grafting procedures (an automated epidermal harvesting system and non-cultured epidermal cell suspension) in the treatment of stable vitiligo.

Background The non-cultured epidermal cell suspension method is a well-established but tedious grafting modality in the management of stable vitiligo. Recently a more user-friendly automated epidermal harvesting system has been introduced. Aim This was a pilot study to compare the efficacy and safety outcomes of the above two grafting procedures. Study design The study was a single-blinded split-body randomised controlled trial. After scientific and ethical clearance, the trial was registered with CTRI (CTRI/2018/05/014225). Thirty consenting patients of stable vitiligo with 60 near-symmetrical patches were recruited. Block randomisation was done using computer-generated randomisation software and each patch was allocated either of the two grafting modalities. Efficacy was assessed by the Physician Global Assessment Scale on serial images and pain by the Numerical Rating Pain Scale. Results and conclusion The non-cultured epidermal cell suspension was found to be an overall statistically superior technique to the automated epidermal harvesting system in terms of efficacy (re-pigmentation). Both donor and recipient site complications were significantly less with the automated epidermal harvesting system grafting and this method had the distinct advantage of being a painless and easy technique with minimal recovery time. A novel observation was that a good colour match and near-complete re-pigmentation occurred in patients with a darker skin colour with both techniques. Limitations The main limitation of our study was the small sample size. Also, the size of the treated patches was limited such that they could be covered by the 5 × 5 cm size of the automated epidermal harvesting system blade. However, a larger area can be covered with multiple sessions.

A dissimulate presentation of histoid Hansen's disease in the form of erythema nodosum leprosum.

Hansen's disease is a chronic infectious granulomatous disease with varied clinical presentation. Histoid Hansen's disease is an important emerging lepromatous subset of Hansen's disease known to mimic varied dermatoses. Occurrence of reactions, especially erythema nodosum leprosum (ENL), is rare in this form of leprosy. We report a case of Histoid Hansen's disease with initial presentation of ENL while undergoing management for infertility.

Acute scrotum: Hansen's disease versus filariasis.

Hansen's disease is caused by Mycobacterium leprae. The disease is known to involve the visceral organs including the testis apart from the skin and nerves in the lepromatous pole of leprosy due to widespread hematogenous dissemination of lepra bacilli. Furthermore, there can be testicular pain during the type 2 reaction in Hansen's disease. Filariasis is a disease caused by the parasitic nematode, Wuchereria bancrofti. This infection most commonly results in lymphedema and secondary vaginal hydrocele with an associated epididymo-orchitis. Acute epididymo-orchitis is either seen in the acute phase or as a part of secondary bacterial infections. The particular interest of this paper is to report the case of Hansen's disease who presented with testicular pain and posed a diagnostic dilemma when his pain did not respond to the standard mode of treatment and an alternate rare diagnosis was sought. This case report also emphasizes the need of reconsideration of diagnosis when the patient is not responding to standard therapy.
