RESUMEN
Eruptive pseudoangiomatosis is a rare viral exanthem characterized by acute onset of hemangiomata-like lesions, however, histological findings are distinct from that of true angiomas. This entity has been reported from Europe, North America, Japan, and Korea till date. Here, we report 12 cases of eruptive pseudoangiomatosis from a tertiary care hospital in Punjab.

RESUMEN
The present study reports the purification of a lectin from Colocasia esculenta (L.) Schott corms and evaluation of its anti-insect potential towards Bactrocera cucurbitae (Coquilett). The lectin was found to be specific towards N-acetyl-D-lactosamine (LacNac), a disaccharide and asialofetuin, a desialylated serum glycoprotein in hemagglutination inhibition assay. Asialofetuin was used as a ligand to purify Colocasia esculenta agglutinin (CEA) by affinity chromatography. The purity of CEA was ascertained by the presence of a single band in reducing SDS-PAGE at pH 8.3. The affinity purified CEA was employed in artificial diet bioassay of second instar larvae (64-72 hr old) of the B. cucurbitae at concentrations ranging between 10-160 µg ml-1. The lectin significantly (p<0.01) decreased the percent pupation and emergence with respect to control. Effect on various enzymes was studied by employing LC50 (51.6 µg ml-1) CEA in the artificial diet bioassay of second instar larvae. All the enzymes tested namely esterases, phosphatases (acid and alkaline), superoxide dismutases, catalase and glutathione-S-transferase showed a significant (p<0.01, p<0.05) increase in their enzyme and specific activities. These results showed that CEA affected normal growth and development and presented stress to the larvae, activating their detoxification and anti-oxidant systems. Thus, the lectin seems to be a useful candidate for the control measures of B. cucurbitae under the integrated pest management (IPM) system.
RESUMEN
Background and Aims: Skin and mucocutaneous disorders are common in HIV infection and may be the earliest manifestation of the disease. The spectrum of these disorders is wide and may vary in different regions due to varying prevalence of various microbial agents. Therefore, we studied the seroprevalence of HIV infection in patients presenting with skin and mucocutaneous disorders and clinical and regional epidemiological profile of seropositive patients. Methods: Eleven hundred and seventy patients having any type of skin or mucocutaneous disorders were screened for HIV infection (NACO guidelines) after recording their clinical and epidemiological profile. Results: Of the 1170 patients screened, 38 (3.24%) were found to be positive for HIV 1 and none for HIV 2 antibodies. Seropositive patients belonged to the age group of 9 to 48 years, with a male:female ratio of 0.9:1. Heterosexuality was the most common mode of transmission (86.8%). A wide range of infectious and noninfectious lesions were observed and herpes zoster was the most common infectious disease (31.5%) followed by mucocutaneous candidiasis (26.3%). The most common noninfectious manifestation was seborrhoeic dermatitis (18.4%) followed by pruritic papular eruptions (7.9%). Conclusion: High prevalence and wide variety of skin and mucocutaneous disorders in HIV-positive patients highlight the importance of better vigilance and early suspicion of HIV infection in such patients.
