BACKGROUND/AIMS To evaluate the psychometric properties of the Hong Kong Montreal Cognitive Assessment (HK-MoCA) in patients with cerebral small vessel disease (SVD). METHODS 40 SVD patients and 40 matched controls were recruited. Concurrent and criterion validity, inter-rater and test-retest reliability, internal consistency of the HK-MoCA were examined(More)
This prospective study aimed to evaluate the diagnostic utilities of neutrophil CD64 expression for the identification of early-onset clinical infection and pneumonia in term infants and to define the optimal cutoff value so that it may act as a reference with which future studies can be compared. Term newborns in whom infection was suspected when they were(More)
Very low birth weight (VLBW) infants with suspected late-onset infection requiring sepsis screening were enrolled in a prospective study to evaluate the diagnostic utilities of a comprehensive panel of key chemokines and cytokines, both individually and in combination, to identify diagnostic markers for early recognition of bacterial sepsis and necrotizing(More)
Despite extensive research into poststroke depression (PSD), the role played by lesion location in the pathogenesis of PSD remains uncertain. The aim of this study was to estimate the magnetic resonance imaging (MRI) correlates of PSD in Chinese patients with first or recurrent stroke. A total of 591 patients with acute ischemic stroke admitted to the acute(More)
AIMS Twenty-six cases of granulomatous mastitis were examined to determine the common histological and clinical features and the possible association with micro-organisms. METHODS A retrospective review of the clinical and histological features of these cases was undertaken, including granuloma, inflammatory cell infiltrate, multinucleated giant cells,(More)
The purpose of this paper is to compare volume- and boundary-based morphometry methods by applying them in the statistical analysis of 2-D shapes. The methods discussed in the first category include voxel-, deformation-, and tensor-based morphometry. The active shape model is demonstrated as an example of the second category of methods. The test data are(More)
Neurocutaneous melanosis is a rare congenital syndrome characterized by large or multiple congenital melanocytic nevi and benign or malignant pigment cell tumors of the leptomeninges. The prognosis is extremely poor for symptomatic patients, even in the absence of malignant melanoma. We present serial MR imaging findings in the brain and spine of a child(More)
BACKGROUND AND PURPOSE Cerebral microbleeds (CMB) are common in stroke survivors and the community-dwelling elderly. The clinical significance of CMB in the development of depression after a stroke is unknown. This study examined the association between poststroke depression (PSD) and CMB. METHODS A cohort of 235 patients with acute lacunar stroke(More)
Oesophageal haemangiomas are rare, benign, vascular tumours that have characteristic features on computed tomography and magnetic resonance imaging. This enables radiologists to suggest the correct diagnosis without the need for invasive biopsy. Diagnostic characteristics include phleboliths seen on computed tomography, and intense homogeneous enhancement(More)
OBJECTIVE Proton MR spectroscopy is a recently described technique with high sensitivity and specificity for differentiating breast carcinoma from benign lesions. We evaluated the possible relationship between spectroscopy results and the tumor proliferative index, angiogenesis, and HER2/neu oncogene overexpression. SUBJECTS AND METHODS. We prospectively(More)
