A case of longitudinally extensive transverse myelitis following vaccination against Covid-19.

Background: Longitudinally extensive transverse myelitis (LETM) is a rare subtype of transverse myelitis (TM) that potentially results in relevant disability. Apart from association to neuromyelitis optica and other chronic demyelinating diseases of the central nervous system, many other aetiologies are known. Particularly systemic infections and vaccination are considered potential triggers for immune mediated inflammation of the spinal cord.

CD47 is expressed at normal levels in patients with autoimmune haemolytic anaemia and/or immune thrombocytopenia.

CD47 deficiency results in lethal autoimmune haemolytic anaemia (AIHA) and mild spontaneous thrombocytopenia in non-obese diabetic mice. It is unknown whether CD47 has an impact on AIHA of the warm type or autoimmune thrombocytopenia (ITP) in humans. Healthy blood donors (n= 11), patients with AIHA (n= 13), patients with ITP (n= 18) and one patient with Rh(null) phenotype were investigated.

Priority setting in a Canadian surgical department: a case study using program budgeting and marginal analysis.

Introduction: A key mandate of Canadian regional health authorities is to set priorities and allocate resources within a limited finding envelope. The objective in this study was to determine how resources within a surgical program in a Canadian rural hospital might be reallocated to better meet the needs of the local community.

Methods: Early in 2001, at the Canmore General Hospital, Canmore, Alta.
