Coteries may be used to construct permission based distributed mutual exclusion algorithms. One such algorithm is Maekawa's p N algorithm in which the co-terie is constructed based on nite projective planes. This paper presents a token based mutual exclusion algorithm which uses data structures similar to coter-ies, called quorum agreements. The performance… (More)

A 4-year-old girl presented with non-bilious vomiting and loss of appetite and weight. At laparotomy, a non-communicating pyloroduodenal duplication cyst was present. Subtotal excision of the cyst and cauterization of the mucosal lining of the common wall was performed. The post-operative recovery was uneventful.
BACKGROUND Direct immunofluorescence (DIF) is the gold standard in the diagnosis of immunobullous diseases. However, it cannot reliably differentiate various subtypes of subepidermal immune- bullous diseases (SIBD). Salt split technique (SST) could be used under such circumstances to differentiate them. There is paucity of reports in the Indian literature… (More)
Epidermolysis bullosa acquisita (EBA) is an acquired subepidermal bullous disorder characterized by autoantibodies against Type VII collagen. It usually affects adults; childhood EBA is rare. We describe a 10-year-old girl presenting with recurrent tense blisters predominantly on legs, dorsa of hands and feet accompanied by oral erosions since the age of 5… (More)
Alopecia areata (AA) over scalp is known to present in various shapes and extents of hair loss. Typically it presents as circumscribed patches of alopecia with underlying skin remaining normal. We describe a rare variant of AA presenting in linear band-like form. Only four cases of linear alopecia have been reported in medical literature till today, all… (More)
