ABSTRACT
INTRODUCTION: Periungual, palmar, and plantar warts are difficult to treat with poor treatment response. Intralesional (IL) bleomycin has shown promising results for their treatment in a few reports. However, we need further evidence before opting it for treating difficult sites and resistant warts. Hence, we conducted this study to assess the efficacy and safety of IL bleomycin for the treatment of resistant palmoplantar and periungual warts. METHODS: In this retrospective study, we included all patients who were given IL bleomycin for warts over a year. Maximum three sittings of bleomycin (1 mg/ml) were given monthly, and they were followed up for 3 months after the procedure. The response was categorized as complete, near-complete, significant, moderate, mild, and no clearance for 100%, 75-99%, 50-74%, 25-49%, 1-25%, and 0% clearance, respectively. RESULTS: Out of 29 patients, follow-up details were available only in 19 patients (53 warts). The mean duration was 2.5 ± 1.47 years. The number of past interventions ranged from 2-4. Wart clearance after the first intervention was complete in 36.84%, near-complete in 26.31%, significant in 26.31%, and moderate in 10.53%. Wart clearance after the last intervention was complete in 89.47% and near-complete in 10.52% of patients. However, during 3 months of follow-up after the last injection, 15.78% had a recurrence. None of them had severe local and systemic side effects. CONCLUSIONS: IL bleomycin could be a better treatment option for the treatment of resistant and difficult warts. However, we observed a higher recurrence rate even in a shorter follow-up. Hence, we need further studies with larger samples.
ABSTRACT
Post-kala-azar dermal leishmaniasis (PKDL) is a skin manifestation of visceral leishmaniasis (VL) which develops after apparent cure in some patients. PKDL is considered as the potential reservoir for the VL infection. Molecular epidemiological characterization of L. donovani isolates obtained from VL and PKDL isolates is essentially required in order to understand the transmission dynamics of the VL infection. To date, genetic variation among the VL and PKDL L. donovani isolates was not fully elucidated. Therefore, 14 clinical isolates from VL and 4 clinical isolates from PKDL were speciated by hsp70 and rDNA genes. Further characterization of L. donovani by haspB PCR demonstrates two different genotypes. All PKDL isolates have the same genetic structure. kDNA PCR-RFLP assay revealed 18 different genotypes; however, structural analysis showed the two distinct kDNA genotype population (k = 2). The kDNA fingerprint patterns of parasites from hilly districts were clustered separately from low-land districts. Therefore, further study with a large number of samples is urgently required for systematic characterization of the clinical isolates to track the molecular epidemiology of the Leishmania donovani causing VL and the role of PKDL as a reservoir.
ABSTRACT
INTRODUCTION: Post-kala-azar dermal leishmaniasis (PKDL) is a cutaneous complication appearing after treatment of visceral leishmaniasis, and PKDL patients are considered infectious to sand flies and may therefore play a role in the transmission of VL. We estimated the risk and risk factors of PKDL in patients with past VL treatment in south-eastern Nepal. METHODS: Between February and May 2010 we traced all patients who had received VL treatment during 2000-2009 in five high-endemic districts and screened them for PKDL-like skin lesions. Suspected cases were referred to a tertiary care hospital for confirmation by parasitology (slit skin smear (SSS)) and/or histopathology. We calculated the risk of PKDL using Kaplan-Meier survival curves and exact logistic regression for risk factors. RESULTS: Out of 680 past-treated VL patients, 37(5.4%) presented active skin lesions suspect of PKDL during the survey. Thirty-three of them underwent dermatological assessment, and 16 (2.4%) were ascertained as probable (2) or confirmed (14) PKDL. Survival analysis showed a 1.4% risk of PKDL within 2 years of VL treatment. All 16 had been previously treated with sodium stibogluconate (SSG) for their VL. In 5, treatment had not been completed (≤ 21 injections). Skin lesions developed after a median time interval of 23 months [interquartile range (IQR) 16-40]. We found a higher PKDL rate (29.4%) in those inadequately treated compared to those who received a full SSG course (2.0%). In the logistic regression model, unsupervised treatment [odds ratio (OR) = 8.58, 95% CI 1.21-374.77], and inadequate SSG treatment for VL in the past (OR = 11.68, 95% CI 2.71-45.47) were significantly associated with PKDL. CONCLUSION: The occurrence of PKDL after VL treatment in Nepal is low compared to neighboring countries. Supervised and adequate treatment of VL seems essential to reduce the risk of PKDL development and active surveillance for PKDL is needed.

Leprosy and visceral leishmanias are endemic in Nepal and are both major public health problems. Two patients of visceral leishmaniasis developed leprosy during the course of the disease. Leprosy and visceral leishmaniasis share a similar immunological spectrum and can occur concomitantly in endemic regions.

A 14-month-old boy presented with generalised vesicular eruption involving the face, trunk and extremities accompanied by high grade fever. He had associated redness and purulent discharge from both eyes. Examination revealed erosions on the tongue, soft palate and genitalia with haemorrhagic crusts on the lips and nasal orifices. All laboratory investigations were within normal limits except leucocytosis. Chest x-ray showed left middle zone pneumonitis. Treatment was by paracetamol, antibiotics and oral acyclovir. Desquamation started from the eighth day. Our purpose in reporting this case is to highlight the fact that varicella can be atypical with distal involvement and can present as SJS-TEN overlap syndrome.

Stevens-Johnson syndrome (SJS) is a severe, episodic, acute, mucocutaneous hypersensitivity reaction often caused by drugs. We herewith report a case of SJS with idiopathic thrombocytopenic purpura (ITP) that did not respond to daily oral prednisolone therapy. When treated with dexamethasone pulse therapy, the response was found to be very good. Therefore, we concluded that dexamethasone pulse therapy can be a good and an effective alternative therapy for treatment of such patients. However, to establish its role, further trials in more patients are needed.
