Given two trees (a target T and a pattern P ) and a natural number w, window embedded subtree problems consist in deciding whether P occurs as an embedded subtree of T and/or finding the number of size (at most) w windows of T which contain pattern P as an embedded subtree. P is an embedded subtree of T if P can be obtained by deleting some nodes from T (if a node v is deleted, all edges adjace...

Diarrhoea after renal transplantation is not an uncommon problem [1]. We present the case of a 61-year-old renal transplant recipient on mycophenolate mofetil (MMF) and steroids who presented with chronic diarrhoea and substantial weight loss. The diarrhoea was ascribed to MMF and the patient was converted to enteric-coated mycophenolic sodium (EC-MPS), without effect. Comprehensive workup reve...

We report a case of epidermal inclusion cyst in a 32-year-old male. This was a complication of circumcision that was neglected over years to form stones and urethrocutaneous fistula. Complete excision of the cyst and repair of the fistula were performed successfully. Histopathological examination confirmed our diagnosis.

The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of rare disorders that share many similarities. In addition to sporadic inclusion body myositis (IBM), these include dermatomyositis, polymyositis, and autoimmune necrotizing myopathy. IBM is the most common IIM after age 50 years. Muscle histopathology shows endomysial inflammatory exudates surrounding and invading nonnecr...

Cytomegalovirus infection was believed for sixty years to be caused by an infectious agent. However, the virus causation of cytomegalovirus infection was not established until 1956 when Smith isolated inclusion-producing virus from the salivary gland of a seven month old infant dying of adrenal carcinoma and from renal tissue of a second infant dying of cytomegalic inclusion disease. Before thi...

Applying two definitions of the union of IF-events, P. Grzegorzewski gave two generalizations of the inclusion-exclusion principle for IF-events.In this paper we prove an inclusion-exclusion principle for IF-states based on a method which can also be used to prove Grzegorzewski's inclusion-exclusion principle for probabilities on IF-events.Finally, we give some applications of this principle by...
