Many modern storage systems adopt erasure coding to provide data availability guarantees with low redundancy. Log-based storage is often used to append new data rather than overwrite existing data so as to achieve high update efficiency, but introduces significant I/O overhead during recovery due to reassembling updates from data and parity chunks.

OBJECTIVE To estimate the incidence and determine the characteristic features of venous thromboembolism in the Hong Kong Chinese population. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. SUBJECTS AND METHODS Data were collected during a period of four years (1997-2000). Patients with duplex doppler ultrasonography or(More)
Cytogenetic information on T-cell large granular lymphocyte leukaemia (T-LGL; large granular lymphocytosis) is limited. We report two cases of T-LGL with unusual karyotypic aberrations. The first case showed a novel inv(7)(p15q22) as the sole chromosomal abnormality, while the second case showed an inv(14)(q11q32) with evidence of clonal evolution. The(More)
OBJECTIVES To determine the incidence of multiple myeloma in the Eastern District of Hong Kong Island, the degree of renal impairment at presentation, and its relationship with haematological and biochemical parameters and survival. DESIGN Retrospective study. SUBJECTS AND METHODS Patients with myeloma who were admitted to a regional hospital in Hong(More)
Trisomy 3 has been reported to be associated with marginal zone B-cell lymphoma. However, its occurrence and significance in other B-cell chronic lymphoproliferative disorders has not been fully defined. We report five cases of B-cell chronic lymphoproliferative disorders showing gain of chromosome 3 or 3q. The patients were elderly males who presented with(More)
A prospective study of Chinese patients with megaloblastic anaemia was conducted at the Pamela Youde Nethersole Eastern Hospital from 1 May 1994 to 31 August 1997. Megaloblastic anaemia was diagnosed in 57 patients, 52 of whom were eligible for further evaluation. The median age of these 52 patients was 73.5 years and the male to female ratio was 1.08:1.(More)
Candida arthritis in patients with a haematological malignancy is rare. We report a case of Candida tropicalis arthritis of the knee that occurred in a patient with acute lymphoblastic leukaemia during the recovery phase of post-chemotherapy neutropenia. Although the Candida tropicalis isolates from synovial fluid and synovial tissue were sensitive to(More)
We describe a case of acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) and trisomy 21 as an additional change in a patient who died at relapse after achieving complete remission (CR) for the duration of 20 months. A survey of 42 cases of APL with cytogenetic study performed at our institutionover the past 10 years showed 12 cases (28.6%) having(More)
