BACKGROUND The utility of poststroke cognitive status, namely dementia, cognitive impairment no dementia (CIND), mild cognitive impairment (MCI), and no cognitive impairment (NCI), in predicting dementia has been previously examined. However, no studies to date have compared the ability of subtypes of MCI and CIND to predict dementia in a poststroke(More)
BACKGROUND/AIMS Bronchogenic cysts are congenital lesions of foregut origin, usually found in intrapulmonary or mediastinal locations. However, an esophageal bronchogenic cyst is an uncommon occurrence. The definitive diagnosis is based on histological findings after extirpation of the cyst. Surgical excision of bronchogenic cysts is considered appropriate(More)
Among 407 New England Medical Center Posterior Circulation Registry (NEMC-PCR) patients, 59% had strokes without transient ischemic attacks (TIAs), 24% had TIAs before strokes, and 16% had only posterior circulation TIAs. Embolism was the commonest stroke mechanism accounting for 40% of cases (24% cardiac origin, 14% arterial origin, 2% had potential(More)
Spontaneous massive haemothorax is rare. We describe a healthy 44 year old woman who experience sudden onset chest pain while sleeping. Chest radiograph revealed massive right pleural effusion. Progressive dyspnoea, cold sweating, and tachycardia developed later. A tube thoracostomy was performed immediately and massive haemothorax was noted. An emergency(More)
BACKGROUND AND PURPOSE Arterial stiffness and metabolic syndrome (MetS) are risk factors for ischaemic stroke. We studied the association of arterial stiffness, measured by carotid-femoral pulse wave velocity (PWV) and MetS amongst ischaemic stroke patients. We also investigated the role of inflammation measured by serum erythrocyte sedimentation rate (ESR)(More)
OBJECTIVES Retinal microvasculature changes are associated with vascular events including stroke in healthy populations. It is not known whether retinal microvascular changes predict recurrent vascular events after ischemic stroke. We examined the relationship between retinal microvascular signs and subsequent vascular events in a prospective cohort of 652(More)
Among 407 New England Medical Center Posterior Circulation Registry (NEMC-PCR) patients, the extracranial (ECVA) and intracranial vertebral arteries (ICVA) were the commonest sites of severe occlusive disease followed by the basilar artery (BA). Severe occlusive lesions were found in >1 large artery in 148 patients; 134 had unilateral or bilateral severe(More)
BACKGROUND We assessed whether the standard uptake of 18-fluorodeoxyglucose (18-FDG) in non-small cell lung cancers (NSCLC) differed between stage I and non-stage I tumors. METHODS We reviewed 163 patients with NSCLC who underwent surgical lymph node dissection after tumor resection in 2002-2003. Patients with clinical stage I NSCLC who were investigated(More)
BACKGROUND AND PURPOSE An underlying vascular etiology underpins vascular dementia (VaD) and possibly Alzheimer's disease (AD). Intracranial large artery disease (ICLAD) is a common site of disease among ethnic Asians, and carries a poor prognosis. We studied the prevalence of ICLAD among ethnic Asian patients with AD and VaD. METHODS We recruited(More)
OBJECTIVES This study assessed the maximum standard uptake value of positron emission tomography-computed tomography in patients of pulmonary adenocarcinoma with bronchioloalveolar carcinoma features and whether SUVmax correlates with pathological status, lymph node metastasis, and prognosis. METHODS We retrospectively reviewed 674 patients diagnosed with(More)
