A Comparative Study on Therapeutic Efficacy of Autologous Platelet-rich Plasma, Autologous Platelet-rich Fibrin Matrix, Recombinant Human Epidermal Growth Factor, and Collagen Particles in Nonhealing Leg Ulcers.

Background: Nonhealing leg ulcers are challenging to manage and cause significant patient morbidity. To promote healing, newer techniques focus on delivering/enhancing dermal matrix components. Aim: The aim of this study was to compare the therapeutic efficacy of autologous platelet-rich plasma (PRP), autologous platelet-rich fibrin matrix (PRFM), recombinant human epidermal growth factor (rhEGF), and collagen particles in treating nonhealing leg ulcers. Materials and Methods: Open, randomized prospective study was conducted in a single tertiary center over 2 years where after fulfilling the criteria, randomization was done into four groups. Group A: Autologous PRP (double spin, manual method, weekly); Group B: Autologous PRFM (weekly); Group C: rhEGF (daily application); and Group D: Collagen particles (weekly) along with cleansing, debris removal, and wound dressing. Treatment endpoints were complete healing/6 months of treatment, whichever was earlier. Follow-up was done two weekly by clinical assessment, photographs, and measurement of the ulcer area. Epi info 7 software was used for statistical analysis. Results: A total of 48 patients completed the study, 12 in each group, with mean age: 42.37 ± 4.56 years and male-to-female ratio 2.6:1. Underlying etiology was varicosities (43.75%), traumatic (25%), diabetes (22.91%), and leprosy (8.34%). At baseline, all groups were comparable in terms of patient and ulcer characteristics. Complete healing was seen in 79.17% at the end of 12 weeks: 91.67% of patients from Groups A and B each, and 66.67% from Groups C and D each. The mean time to complete healing was 6.9 ± 2.5 weeks, the least in Group B (4.73 ± 2.3 weeks). Differences between excellent (≥75%) ulcer healing across all groups were statistically significant at the end of 8 weeks where Group B showed maximum improvement. No major adverse events were seen. Conclusion: PRFM resulted in relatively faster ulcer healing compared with other modalities.

Presentation of Hansen's disease as Lucio phenomenon in an Indian male.

Lucio phenomenon is a reactional state described in patients with Lucio leprosy and in a few cases of lepromatous leprosy; it is rarely seen outside Mexico and Central America. We report a case of 35-year old labourer who presented with clinical features classical of Lucio phenomenon without any pre-existing cutaneous nodules or infiltrative lesions of either Lucio or lepromatous leprosy. This case report demonstrates the need to consider Lucio phenomenon in patients presenting with clinical features of medium vessel vasculitis even in areas not endemic for Lucio leprosy.

Leprosy Scenario in Ahmedabad District (Gujarat).

BACKGROUND: In India, leprosy still continues to be one of the major public health problems and demands a continuous awareness for its eradication. The reduction of the load of infection is the cornerstone of leprosy control. AIMS: The aim of the present study was to enumerate the epidemiology of leprosy in the Ahmedabad district of Gujarat. METHODS: Three hundred new cases of leprosy (multidrug therapy cases) and patients who had completed antileprosy treatment and developed new signs and symptoms after that during the period from June 2010 to December 2012 were included in the study. A detailed history, clinical examination, and relevant tests were done. RESULTS: Out of a total of 300 patients, male-to-female ratio was 2.1:1. Family history was positive in 4.3% of patients. Lepromatous leprosy was seen in 27.3%, pure neuritic leprosy occurred in 12 (3.9%), and smear positivity was seen in (44.6%). Thirty (10%) patients developed type 1 reaction and 32 (10.6%) patients had type 2 reaction. Nearly 1.3% of the cases were relapsing cases. LIMITATIONS: The study had geographical limitation and the study did not cater the whole population but only the cases who reported to the hospital. Hence, the social stigma factor associated with leprosy could not be annulled. CONCLUSIONS: Leprosy still prevails and adequate knowledge and clinical skills, sensitive diagnostic tools and proper supply of medicines from the medical end and early reporting of symptoms, compliance regarding medicine intake, and social awareness to null social stigma associated with it from the patient's end may bring the country as a whole to the target of leprosy elimination.

A study of autologous melanocyte transfer in treatment of stable vitiligo.

BACKGROUND: Replenishing melanocytes selectively in vitiliginous macules by autologous melanocytes is a promising treatment. With expertise in culturing melanocytes, it has now become possible to treat larger recipient areas with smaller skin samples. AIM: To study the extent of repigmentation after autologous melanocyte transplantation in patients with stable vitiligo. METHODS: The melanocytes were harvested as an autologous melanocyte rich cell suspension from a donor split thickness graft. Melanocyte culture was performed in selected cases where the melanocyte cell count was insufficient to meet the requirement of the recipient area. These cells were then transplanted to the recipient area that had been superficially dermabraded. RESULTS: An excellent response was seen in 52.17% cases with the autologous melanocyte rich cell suspension (AMRCS) technique and in 50% with the melanocyte culture (MC) technique. CONCLUSION: Autologous melanocyte transplantation can be an effective form of surgical treatment in stable but recalcitrant lesions of vitiligo.
