PRP and its benefit as an adjunctive therapy with subcision and microneedling in atrophic scars: a comparative study.

Context: Scarring is a biological process of wound repair which leads to a difference in the normal structure and function of the skin and manifests as a depressed or raised area. Treatment of scars is challenging. A number of therapeutic approaches like surgical techniques and non-surgical techniques are performed to improve scarring. Aims and Objectives: The aim of this study was to compare the outcome of subcision followed by microneedling versus subcision followed by microneedling and topical platelet-rich plasma (PRP) in atrophic scars. Materials and Methods: A comparative prospective study was conducted at a tertiary care hospital in North India to compare the efficacy of subcision followed by microneedling versus subcision followed by microneedling and topical PRP. A total of 40 cases were taken and were randomly divided into two groups, A and B of 20 patients in each group. Topical PRP was applied as an additional therapy in Group B in the same sitting. Minimum three sittings were done in each patient at an interval of 4 weeks and results were assessed after 1 month of the third session. The statistical software used is Microsoft Excel and SPSS software program, version 24.0 for analysis of data and Microsoft Word to generate graphs and tables. Results: Improvement in scar grading was more in Group B as compared to Group A with statistically significant difference (P = 0.032). There was an improvement in scar grading from grade 4 scar to grade 2 in 15% and 30% patients of Groups A and B, respectively, with improvement in skin texture and pigmentation more in Group B. Conclusion: PRP proved to add to the improvement of grade of atrophic scars when combined with subcision and microneedling.

A Comparative Study of the Efficacy of Methotrexate versus Methotrexate with Apremilast in Moderate to Severe Chronic Plaque Psoriasis.

Background: Psoriasis is an inflammatory systemic disease with a chronic relapsing course. Methotrexate, a dihydrofolate reductase inhibitor, and Apremilast, an oral phosphodiesterase type 4 inhibitor, are currently the mainstay drugs in the treatment of psoriasis. Aims and Objectives: To compare the efficacy of Methotrexate with a combination of Methotrexate and Apremilast in treating chronic plaque psoriasis. Materials and Methods: The present study was a prospective comparative study conducted among 40 patients, aged above 18 years, with clinically diagnosed psoriasis attending Dermatology OPD of a tertiary care hospital in North India. The study utilised a pre-structured proforma to record a detailed demographic profile and clinical examination related to chronic plaque psoriasis. The patients were divided into two groups of 20 each. Group A was treated with oral Methotrexate, while Group B was treated with oral Apremilast and Methotrexate, and they were evaluated every 4 weeks for 12 weeks. Necessary investigations were done wherever indicated. Results: The male-to-female ratio was 1.35, and the majority (55.0%) of patients belonged to the age group of 31-50 years. 27.5% of patients had comorbidities like diabetes, hypertension, etc., The mean PASI score of group A at the first, second and third follow-ups was higher than that of group B. The reduction in mean PASI score was statistically significant in group B at successive follow-ups, with a percentage improvement of 89.4% at the end of 12 weeks. Conclusions: When comparing monotherapy with methotrexate and multidrug therapy with Methotrexate and Apremilast, multidrug therapy had better efficacy.

Dyskeratosis congenita- management and review of complications: a case report.

Among the inherited bone marrow failure disorders, dyskeratosis congenita is an X-linked inherited disorder arising as a consequence of short telomere and mutations in telomere biology. Production of the altered protein dyskerin, leads to vulnerable skin, nails, and teeth which lead to higher permeability for noxious agents which can induce carcinogenesis accounting for the classical triad of skin pigmentation, nail dystrophy and oral leukoplakia. This condition is fatal and patients succumb to aplastic anemia, malignancy or immunocompromised state. We present a young male with the classic clinical triad and avascular necrosis of both femoral heads, with no evidence of hematologic anomaly or any malignancy. He was managed for osteonecrosis with uncemented total hip arthroplasty for the symptomatic left hip. Our case represents a benign form of such a fatal and rare condition, which if detected and managed early can result in improved quality of life for the patient suffering from this disorder. This patient is under our meticulous follow-up for the last 2 years in order to determine any late development of complications before being labelled as a variant of this syndrome.

Comparative evaluation of topical calcipotriol versus coal tar and salicylic acid ointment in chronic plaque psoriasis.

BACKGROUND: Calcipotriol is a newer topical treatment option available for plaque psoriasis and coal tar being one of the oldest treatment and still in use. AIMS: To evaluate and compare the differences in terms of efficacy, safety and relapse with Calcipotriol 0.005% (50 mcg/gm) and 6% coal tar and 3% salicylic ointment in patients with Plaque psoriasis. SETTING and DESIGNS: Study conducted on 60 patients of plaque psoriasis, who attended the skin OPD in our hospital. METHODS: The patients with mild to moderate plaque psoriasis were selected. 60 patients were enrolled for the study after obtaining informed consent. Subjects were asked to apply Calcipotriol 0.005% (50 mcg/gm) (Heximar Win care) twice a day on the right side plaques and on left side plaques, Petroleum jelly (Vaseline) in the morning and 6% coal tar and 3% salicylic ointment (Protar® Percos) at nighttime. PASI score was used to assess the reponse to therapy at 2nd, 4th, 6th and 8th week. After treatment subjects were observed for 6 weeks for any relapse. STATISTICAL ANALYSIS: It was done by paired t-test and independent sample t-test. CONCLUSIONS: The results showed that statistically significant difference was seen in the mean percentage reduction of PASI score between both the groups, at all the assessment visits, 2, 4, 6, and 8 weeks, the mean percentage reduction at 2 weeks for calcipotriol being 21±12.06 and for coal tar being 13.44±11.19 (P=0.000), at 4 weeks for calcipotriol was 40±16.71 and for coal tar 25±99 (P=0.000), at 6 weeks for calcipotriol was 53.99+-22.43 and for coal tar 41±21.23 (P=0.002), at 8 weeks for calcipotriol was 62.73±24.04 and for coal tar was 51.53±23.27 (P=0.11). Relapse was seen in 5/60 (8.3%) of patients on calcipotriol treated side and 9/60 (15%) of patients with coal tar treated side. Thus it can be concluded that calcipotriol cream is more efficacious when compared with coal tar and does have a quick response. It is well tolerated and acceptable cosmetically.

Study on epidemiology of cutaneous amyloidosis in northern India and effectiveness of dimethylsulphoxide in cutaneous amyloidosis.

CONTEXT: Amyloidosis, which is characterized by the extracellular deposition of a proteinaceous substance, is usually associated with considerable tissue dysfunction. However, the etiology of the disease remains uncertain and the treatment disappointing. AIM: 1. To know the epidemiology of cutaneous amyloidosis 2. To evaluate the effect of dimethylsulphoxide on cutaneous amyloidosis. SETTINGS AND DESIGN: Data was collected from patients attending the Outpatient Department (OPD) over a period of one year. MATERIAL AND METHODS: Patients were screened on the basis of signs and symptoms and then confirmed histologically. A total of 62 patients who were suspected to be suffering from amyloidosis on the basis of clinical signs and symptoms and 38 patients who were further confirmed histopathologically underwent the treatment. STATISTICAL ANALYSIS USED: Chi-square test was used for testing the significance of proportions. RESULTS: 63.15 percent of the patients had macular amyloidosis and the interscapular area was the most common area involved (52.63%). Pruritus, pigmentation, and papules responded excellently to dimethylsulphoxide after one month of treatment. CONCLUSIONS: Cutaneous amyloidosis is a disease found in middle-aged persons, with a female preponderance, and dimethylsulphoxide seems to be an effective therapy.

Micropathological changes in the sub-epidermal zone of normal appearing skin in leprosy.

Leprosy is a chronic inflammatory disease caused by Mycobacterium leprae, which affects not only the peripheral nerves and skin but also various internal viscera through the hematogenous spread, especially in lepromatous cases. The micropathological changes in epidermis, nerves and skin appendages from lesioned skin reported by various authors but reports of involvement of apparently normal sites are few. We investigated skin biopsy material taken from 130 patients with clinically diagnosed leprosy. Biopsies were taken at least 10 cm away from site of lesion. Hematoxylin and Eosin staining and Harada's modified Allochrome method for acid-fast bacilli were applied for histological investigations. The pattern of leprosy among the patients were indeterminate in 53 cases (40.8%), tuberculoid in 29 cases (22.3%), borderline tuberculoid in 14 cases (10.8%), borderline leprosy in ten cases (7.7%), borderline lepromatous in nine cases (6.9%) and lepromatous leprosy in 15 cases (11.5%). The changes were seen in sub-epidermal zone of normal appearing skin in all type of leprosy, but involvement was greater at the lepromatous end of the spectrum compared to tuberculoid end. Acid-fast bacillus (AFB) was seen in subepidermal zone of normal appearing site. Presence of AFB is significant as far as dissemination and transmission of disease is concerned.

Histopathological changes in the arrector pili muscle of normal appearing skin in leprosy patients.

BACKGROUND: Leprosy is a chronic inflammatory disease caused by Mycobacterium leprae, which affects not only the peripheral nerves and skin, but also various internal viscera through hematogenous spread, especially in lepromatous cases. Histology in its own way plays a vital role, not only in classifying the established lesion, but also in confirming the clinical diagnosis. During the latent period of subclinical involvement, the apparently normal looking skin might also be undergoing some pathological changes. METHODS: We investigated skin biopsy material taken from 60 patients with clinically diagnosed leprosy at Subharti Hospital, Subharti Medical College, Meerut, India. Hematoxylin and eosin staining and Harada's modified allochrome method for acid-fast bacilli were applied for histological investigations. RESULTS: The pattern of leprosy among the patients was indeterminate in 25 cases (41.7%), tuberculoid in 14 (23.3%), borderline tuberculoid in six (10%), borderline leprosy in four (6.7%), borderline lepromatous in four (6.7%), and lepromatous leprosy in seven (11.7%). Changes were seen in the arrector pili muscle of normal appearing skin in all types of leprosy, but involvement was greater at the lepromatous end of the spectrum compared to the tuberculoid end. CONCLUSIONS: Results of this study revealed definitive histological changes in the arrector pili muscle in normal appearing skin. The presence of AFB is significant as far as dissemination and transmission of the disease is concerned.
