PURPOSE Transdural herniation of the spinal cord is a rarely reported clinical entity, and many of the existing reports were published before the advent of MR imaging. We describe five current cases and compare them with findings in 25 cases reported in the literature to delineate the clinical and imaging spectra of transdural spinal cord herniation. (More)
The ability to determine the characteristics of peripheral nerve fiber size distributions would provide additional information to clinicians for the diagnosis of specific pathologies of the peripheral nervous system. Investigation of these conditions, using electro-diagnostic techniques, is advantageous in the sense that such techniques tend to be minimally(More)
PURPOSE To determine the clinical usefulness of MR imaging to screen for vascular compression of the lateral medulla, considered by some to be responsible for neurogenic hypertension. METHODS MR images and clinical records of 120 adults who had received brain MR imaging for any reason were divided into two groups: group 1 (n = 60) consisted of patients(More)
The case of a 52 year old woman with chronic severe refractory thrombocytopenia is presented. Over a three year period, her platelet count was persistently less than 20 x 10(9)/litre (normal range, 150-400). She required repeated hospital admission for management of bleeding and received multiple blood transfusions. She was given repeated courses of(More)
AIMS To test the hypothesis that the abnormal fibrous stroma of bone marrow found after treatment of disseminated neuroblastoma represents traumatic scarring. METHODS Twenty six restaging bone marrow biopsy specimens from 14 children with disseminated neuroblastoma were compared with 37 from 37 children with acute lymphoblastic leukaemia. They were(More)
We report the results of 20 consecutive laparoscopic splenectomies performed on haematology patients for a number of indications. Our series includes patients up to 77 years of age at the time of surgery and removal of spleens weighing up to 3530 g. The most significant benefit is the early rate of discharge post-operatively (median 2 d); however, there is(More)
In this paper we prove two results. The first is an extension of a result of Dirac which says that any set of n vertices of an n-connected graph lies in a cycle. We prove that if V ′ is a set of at most 2n vertices in an n-connected graph G, then G has, as a minor, a cycle using all of the vertices of V′. The second result says that if G is an n+1-connected(More)
