A retrospective comparative study of outcome with surgical excision and repair versus nonsurgical and ablative treatments for basal cell carcinoma.

BACKGROUND: There are few studies on basal cell carcinoma (BCC) from India. Long-term follow-up is available in only one study and the aesthetic outcome of treatment has not been evaluated in Indian patients. AIMS: In this retrospective study on BCC, we compared treatment failure, recurrence rates and aesthetic outcomes on long-term follow-up between surgical excision and repair, and nonsurgical and ablative treatments. METHODS: Records of patients with BCC treated in the dermatologic surgery clinic over the past 10 years were analyzed. Patients with histopathologically confirmed BCC who could be contacted were evaluated for recurrence, treatment failure, overall satisfaction and aesthetic outcomes by global aesthetic improvement scale. RESULTS: Out of 98 patients, 72 were contactable. Four patients received both nonsurgical and ablative treatments and surgical excision and repair sequentially and were excluded. The mean age of patients was 57.9 ± 15.8 years (24-90 years) and the male: female ratio was 1.6:1. The most common site involved was the face (72.1%) followed by trunk and scalp, and the most common type of BCC was the pigmented superficial type (33.8%), followed by the pigmented noduloulcerative type (16.2%). There was no significant difference between the groups in the number of high-risk cases. The mean follow-up period was 37.1 ± 31.4 (range, 4-120) months. Fifty one patients were treated with surgical excision and repair, and 17 with nonsurgical and ablative treatments (9-imiquimod, 5-cryotherapy, 4-radiotherapy). Treatment failure was seen in 5 (7.4%) patients, all in the nonsurgical and ablative treatments group (P = 0.0006). Recurrence was seen in 2 (2.9%) patients, both in the surgical excision and repair group (P > 0.05). Mean patient satisfaction was significantly higher with surgical excision and repair, though there was no significant difference in the Global Aesthetic Improvement Scale between the groups. LIMITATIONS: The sample size was low. Only telephonic and pictorial assessments were done where the patient could not come for follow-up. CONCLUSIONS: Surgical excision and repair was associated with better outcomes than nonsurgical and ablative treatments. Treatment failures and adverse events were high with nonsurgical and ablative treatments. The recurrence rate was low.

Chromoblastomycosis in India: Review of 169 cases.

Chromoblastomycosis (CBM) is a chronic, progressive, cutaneous and subcutaneous fungal infection following the traumatic implantation of certain dematiaceous fungi. The disease has worldwide prevalence with predominant cases reported from humid tropical and subtropical regions of America, Asia, and Africa. Diagnosis is often delayed or misdirected either due to poor degree of clinical suspicions or clinical simulation of dermatological conditions. The infection is not uncommon in India and several case reports from the sub-Himalayan belt and western and eastern coasts of India have been published; however, very few have reviewed the cases. We reviewed 169 cases published in English literature from India during 1957 through May 2016, including 2 recent cases from our institute. A tremendous increase in the number of reported cases was noticed since 2012, since which, more than 50% of the cases had been published. A majority of the patients (74.1%) were involved in various agricultural activities directly or indirectly. The mean age at presentation was 43.3 years ± 16.0, with male to female ratio of 4.2:1. The duration of disease at the time of presentation varied from 20 days to 35 years. Any history of trauma was recalled only in 33.8% of the studied cases. The lower extremity was the most common site afflicted, followed by the upper extremity. The culture was positive in 80.3% of the cases with Fonsecaea pedrosoi, isolated as the most common fungal pathogen, followed by Cladophialophora carrionii. Although all the commercially available antifungals were prescribed in these cases, itraconazole and terbinafine were the most commonly used, either alone or in combination with other drugs/physical methods, with variable degrees of outcome. Combinations of different treatment modalities (chemotherapy and physical methods) yielded a cure rate of 86.3%. CBM is refractory to treatment and no single antifungal agent or regimen has demonstrated satisfactory results. Increased awareness with early clinical suspicion of the disease and adequate therapy are necessary to improve the outcome. However, depending upon the causative agent, disease severity, and the choice of antifungals, variable outcomes can be observed.

Intralesional injection of Mycobacterium w vaccine vs imiquimod, 5%, cream in patients with anogenital warts: a randomized clinical trial.

IMPORTANCE: Intralesional antigen therapy has been used in the treatment of anogenital warts (AGWs), but it has not been compared with existing therapies. Evidence of its efficacy is not strong. OBJECTIVE: To compare the efficacy and safety of intralesional Mycobacterium w (Mw) vaccine with that of imiquimod, 5%, cream in the treatment of AGWs, as well as changes in human papillomavirus (HPV)-6 and HPV-11 viral loads. DESIGN, SETTING, AND PARTICIPANTS: A double-blind randomized clinical trial was conducted in New Delhi, India, between February 2009 and July 2012 and included a 3-month follow-up. Of 159 patients with AGWs who were screened, 89 were randomized. INTERVENTIONS: Patients received either imiquimod, 5%, cream and an intralesional vehicle (imiquimod group: 44 patients) or vehicle cream and intralesional Mw vaccine (Mw group: 45 patients). MAIN OUTCOMES AND MEASURES: The primary end point was complete clinical remission of visible AGWs. Secondary measures included the percentage of reduction in the surface area of AGWs and viral load for HPV-6 and HPV-11. Viral load was measured by real-time quantitative polymerase chain reaction. RESULTS: In the intention-to-treat analysis, 59% (n = 26) of the patients in the imiquimod group and 67% (n = 30) of those in the Mw group had complete resolution (P = .52). Eighteen HPV genotypes, including high-risk genotypes, were detected, with no significant differences between the treatment groups (all P > .05). There was a significant decline in the mean viral loads of HPV-6 (from 0.011 × 108 to 0.00000154 × 108 copies/mg of tissue; P = .003) and HPV-11 (from 0.121 × 108 to 0.017 × 108 copies/mg of tissue; P = .03) after treatment in the Mw group but only in the viral load of HPV-6 (from 1.41 × 108 to 0.004 × 108 copies/mg of tissue; P = .01) in the imiquimod group. There was no recurrence of AGWs in patients with complete clearance at the 3-month follow-up and no serious adverse events. CONCLUSIONS AND RELEVANCE: Imiquimod, 5%, and the Mw vaccine were equally effective in achieving clinical and virologic clearance for HPV-6. A significant decline in the HPV-11 viral load was achieved only with the Mw vaccine. Efficacy and safety of intralesional Mw vaccine is comparable to that of imiquimod, 5%, in treatment of AGWs.

Drug utilization study in dermatology in a tertiary hospital in Delhi.

The present study was undertaken to describe patterns of dermatological drug utilization in a tertiary hospital in Delhi by measuring WHO delineated drug use indicators. Six hundred and six prescriptions of dermatology out-patients were analyzed and the data collected were used to evaluate the following drug use indicators: average number of drug per prescription, average consultation time, percentage of drugs prescribed by generic name, percentage of encounters with an antibiotic prescribed, percentage of encounters with an injection prescribed and percentage of drug prescribed from the essential drugs list or formulary. The average number of drugs per prescription +/- SD was found to be 2.6 +/- 1.2, average consultation time +/- SD was 4.4 +/- 2.6 minutes, percentage of drug prescribed by generic name was 6.98, percentage of encounters with an antibiotic and injection prescribed were 46.86 and 6.76 respectively and 23% of the total drugs prescribed were from Delhi State Essential Drugs Formulary.
