Publication Comparative study of Methotrexate and Cyclosporine in the treatment of Psoriasis(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2010) Karn, D; Amatya, A; Khatri, RAbstract Background Psoriasis is a chronic skin disease characterized by sharply demarcated, erythematous squamous lesions, with an estimated worldwide prevalence of 0 to 11.8%. Methotrexate (MTX) and cyclosporine (CsA) are well known systemic therapies for moderate to severe chronic plague psoriasis. Objective The aim of this study is compare the efficacy of methotrexate and cyclosporine in the treatment of Psoriasis. Methods A prospective randomized study was conducting at the Dhulikhel Hospital, KUTH, Dhulikhel during November 2008 to July 2009 with the objective to compare the effectiveness, side effects and cost of MTX and CsA treatment in a context reflecting normal clinical practice. Results A total of 64 patients (33 receiving MTX and 31 receiving CsA) were enrolled. These patients were followed every week for first month and their PASI score and side effects were recorded at 0, 1st, 2nd and 3rd month interval. In the study, the mean (± S.E) PASI score at base line was 23.34 ± 1.12 for MTX and 21.25 ± 1.07 for CsA group. After 12 weeks of treatment the mean ± S.E PASI score found to be 5.37 ± 0.42 for MTX and 4.56 ± 0.41 for CsA group. The difference in the response between the groups acquired statistically not significance (p=0.160 > 0.05) meaning there is no difference in the effectiveness of MTX and CsA. Conclusions The efficacy, side effects, ease of administration (once weekly vs. twice daily treatment) and cost, it seems that treatment of psoriasis patient with systemic therapy using MTX is preferable than CsA even though, both have similar clinical efficacy.

Reported prevalence varies from 1/100,000 in Denmark to 1 in 30- 35,000 in northern England and Scotland.1 Darier’s disease has been reported from other parts of the world, however,there has been no reported cases in Nepal. It is an inherited autosomal dominat disease characterized by dark crusty lesions over the seborrheic areas of the skin. We are reporting a case of Darier’s disease in a Nepalese patient who developed skin leison’s over his face and body at the age of 12 years. We took skin punch biopsy from the leisons, which showed findings suggestive of Darier’s disease. Our case was treated with isotrerenoin and topical keratolytics. He responded with the given treatment within two weeks of therapy.Publication Emerging trends of nosocomial Citrobacter species surgical wound infection: concern for infection control(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2010) Thapa, B; Karn, D; Mahat, KAbstract Background Surgical wound infection is a common problem among patients who undergo operation. Several factors play important role in this infection process including endemic nosocomial infection without proper infection control measures. Objectives To study the occurrence of the pathogens in post-operative wound infections, their antibiotic resistance patterns, and comparison with published reports. Methods Various specimens obtained from the surgical wound during a period of four months were processed for bacteriological culture in the Department of Microbiology, Kathmandu Medical College, Kathmandu. Antibiotic susceptibility test was performed by Kirby-Bauer disk diffusion test for pathogens isolated. The relevant literatures were searched and compared with the present study. Results Among 79 culture positive cultures, Citrobacter sp. (n=23) was most frequently isolated from surgical wound infection. Twenty strains were multidrug resistant. In comparison with other studies, this study highlights the emergence multi-drug resistant Citrobacter sp. as a leading cause of surgical wound infection. E. coli, Staphylococcus aureus, Acinetobacter sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus sp., and Enterobacter sp. were also isolated from 19, 13, 10, 8, 2, 2, and 2 cultures, respectively. More than 50% of these pathogens were resistant to most of the β-lactam antibiotics tested and most of them were multi-drug resistant while these pathogens showed variable level of resistance to fluroquinolones and amino glycosides. Conclusion The frequent isolation of multi-drug resistant nosocomial strains of Citrobacter sp. in surgical wound infection is a remarkable trend. This pathogen and their resistant genes could be endemic to the institution and can cause difficult-to-treat infection if infection control committee is not revitalized and infection control strategies are not implemented. Key words Citrobacter sp.; Multi-drug resistant; surgical wound infection.Publication Prevalence of Skin Diseases in Kavre District, Nepal(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2010) Karn, D; Khatri, R; Timalsina, MAbstract Background Skin is the major interface of human to the environment . It is the major susceptible organ for any disease. Wide prevalence of skin diseases in the community is a well established fact. Objectve The aim of this study is to determine the prevalence of skin diseases among the general population of Kavre District,Nepal . Methods This is a hospital based, retrospective study done among all the patients visiting Dhulikhel Hospital, Kathmandu University Teaching Hospital, in Dhulikhel, Kavre during the year 2007-2008 AD. Data were obtained from the hospital out-patient records and analyzed. The total number of patients who visited the hospital were 74,279 (male-30,809 female- 43,470), out of which 7374 (9 .92 %), male 4155, female 3219, visited the Dermatology Department. Among this total study population now comparative study of the prevalence of skin diseases was performed based on sex, age and type of dermatological condition. Results The overall prevalence of skin diseases were 9.92% with slight higher rates seen among males ( 56.34 %) than females (43.65 %).Non-infective conditions , 6063 ( 82.22% ) outweighed infective conditions 1311 (17.78 %), commonest one being the pigmentary disorders (32.56 %) and in the age group 16-35 years old (31.23% ). Conclusion This study demonstrates that skin diseases are one of the most prevalent disease condition among the general population, representing a major public health problem. Keywords Prevalence; infective diseases; non-infective diseases.
