Non infective bullous lesions: a diagnostic challenge in a minimally equipped centre- based solely on microscopic findings.
Vesicobullous lesions of skin may occur in different forms of dermatosis, which include various inflammatory, infective, autoimmune, drug induced as well as genetic conditions. Autoimmune bullous lesions, may be fatal if not treated with appropriate agents. Bearing in mind, the morbidity of these diseases, it is important to establish a firm diagnosis. ⋯ Further subtyping was done based on additional histopathological features and clinical correlation. All the patients responded appropriately to the treatment and the results correlated well with the immunofluorescence done in a few cases. This study lays emphasis upon the histopathology and clinical features keeping in consideration of the lack of ancillary techniques in many centres especially in the developing world.

Biofilm formation of Candida Spp. isolated from the vagina and antibiofilm activities of lactic acid bacteria on the these Candida Isolates.
In this study, it was aimed to investigate the effects of bacterial cells and cell-free filtrates of Lactobacillus acidophilus 8MR7 and Lactobacillus paracasei subspecies paracasei 10MR8 on the biofilm formation of 3 Candida tropicalis, 3 C. glabrata and 12 C. albicans isolated from the vagina and identified their virulence factors. ⋯ These isolates promise hope as potential bacteria that can be used for anti-adhesion purposes in health-care materials.

Bio fabrication of gold nanoparticles and their combination with chemotherapy and ultrasound for effective treatment of tumors.
Chemotherapy is one of the important medical option for the cancer therapy, but still new combination of therapeutic treatment methods are needed to achieve efficient anti tumor activity. In this work, Pueraria lobata leaf extract was utilized as a bio reductant for the fabrication of the Gold nanoparticles (Au-NPs) by an ecological approach without using any harmful chemical. This work also evaluates whether the combined effect of chemotherapy along with Au-NPs and Ultrasound (US) is effective over the tumors or not. ⋯ In conclusion, Pueraria lobata leaf extract mediated synthesis of Au-NPs by an eco-friendly approach was reported in this work. The plant biomolecules of the extract were involved in the reduction and capping of the Au-NPs formed. The major conclusion is that addition of Au-NPs with chemotherapy and ultrasound has shown more effective anti-tumor activity.

Comparative StudyAnalysis of clinical and virologic features in Hepatitis B e Antigen (HbeAg)-negative and HbeAg-positive Egyptian chronic hepatitis B patients.
HBeAg-negative chronic hepatitis B infection has a divergent clinical course from that of HBeAg-positive infection. ⋯ HBeAg-negative patients compared with HBeAg-positive patients had older age, lower ALT and serum HBVDNA levels, but more incidence of HCC.
