To clarify the relationship between long-term prognosis of patients with stroke and their MRI findings, 103 patients with initial cerebral thrombosis, who survived more than three months after the ictus, were studied for five years. The mean age of 98 patients (T group), who were followed up completely, was 73.1 years-old and 65 were men. The age-matched controls consisted of two groups: 65 subjects, who had hypertension and/or diabetes without a history of stroke (R group), and 85 subjects, who had any hypertension, diabetes and stroke (N group). MRI findings were divided into six categories: 1) types of causative lesion, 2) grades of periventricular hyperintensity (none, rims/caps, patchy, diffuse PVH), 3) number of spotty lesions, 4) presence of silent infarction. 5) ventricular dilatation, and 6) extents of brain atrophy. Types of causative lesion were subdivided into 3 subtypes; infarction of the perforating artery territory (P type), infarction of the cortical artery territory (C type), and brainstem infarction (B type). The presence of vascular risks and dementia, and the extent of activity of daily living (ADL) were assessed. The P, C, and B types were identified by MRI in 46, 36, and 16 of the T group, respectively. Motor impairment, dementia, and an ADL status of complete dependence at discharge were also seen in 84, 44, and 22, respectively. In the T group, 33 patients died during five years, which resulted in a cumulative mortality rate of 33.7% and an annual mortality rate of 8.2%. Based on log-rank analysis, the survival rate of the T group revealed was significantly lower than those of the R and N groups. The recurrent rate in the T group (annual stroke recurrence rate was 4.0%) was higher than in the R and N groups, but stroke recurrence was not the cause of death and two thirds of deaths were due to aspiration pneumonia and/or asphyxia. Cox hazard regression analysis for death due to respiratory diseases showed that the hazard ratios of infarction, patchy PVH, and more than 4 spotty lesions were 8.87 (p < .001), 0.31 (p = .058), and 0.44 (p = .098), respectively. Compared to the survival group, rates of complete dependence in ADL, dementia, and brain atrophy were significantly higher in the death group with low incidences of the P type and patchy PVH, which indicated small vessel disease. These findings suggested that in patients with cerebral thrombosis, even in the chronic phase, care should be taken to prevent pneumonia and/or asphyxia due to bulbar palsy. Furthermore, no MRI findings were distinct predictors of long-term prognosis, although infarction based on the small vessel disease had rather good outcome in terms of respiratory disease.

Retention of teeth into advanced age makes caries and periodontitis lifelong concerns. Dental caries occurs when acidic metabolites of oral streptococci dissolve enamel and dentin. Dissolution progresses to cavitation and, if untreated, to bacterial invasion of dental pulp, whereby oral bacteria access the bloodstream. Oral organisms have been linked to infections of the endocardium, meninges, mediastinum, vertebrae, hepatobiliary system, and prosthetic joints. Periodontitis is a pathogen-specific, lytic inflammatory reaction to dental plaque that degrades the tooth attachment. Periodontal disease is more severe and less readily controlled in people with diabetes; impaired glycemic control may exacerbate host response. Aspiration of oropharyngeal (including periodontal) pathogens is the dominant cause of nursing home-acquired pneumonia; factors reflecting poor oral health strongly correlate with increased risk of developing aspiration pneumonia. Bloodborne periodontopathic organisms may play a role in atherosclerosis. Daily oral hygiene practice and receipt of regular dental care are cost-effective means for minimizing morbidity of oral infections and their nonoral sequelae.

The third most common stroke complication is infection. We studied the rates of aspiration pneumonia and urinary tract infection (UTI), their risk factors and their effect on outcome in the 1455 Glycine Antagonist (Gavestinel) in Neuroprotection (GAIN) International patients with ischaemic stroke. Forward stepwise logistic regression and Cox proportional hazards modelling identified baseline factors that predicted events and the independent effect of events up to day 7 on poor stroke outcome at 3 months in patients alive at day 7, after correcting for prognostic factors. Higher baseline National Institute of Health Stroke Scale (NIHSS) and age, male gender, history of diabetes and stroke subtype predicted pneumonia, which occurred in 13.6% of patients. Female gender and higher baseline NIHSS and age predicted UTI, which occurred in 17.2% of patients. Pneumonia was associated with poor outcome by mortality (hazard ratio, 2.2; 95% confidence interval, 1.5-3.3), Barthel index (<60) (odds ratio, 3.8; 2.2-6.7), NIHSS (4.9; 1.7-14) and Rankin scale (>/=2) (3.4; 1.4-8.3). UTI was associated with Barthel index (1.9; 1.2-2.9), NIHSS (2.2; 1.2-4.0) and Rankin scale (3.1; 1.6-4.9). Pneumonia and UTI are independently associated with stroke poor outcome. Patients with identified risk factors must be closely monitored for infection.

A 95-year-old woman complained of sudden onset of disturbance of consciousness and right hemiparesis on April 20, 2003 and was admitted on the next day. She was drowsy and showed moderate right motor and sensory hemiparesis. The blood laboratory tests showed slight inflammatory reaction. A low density area was found in the left basal ganglia by brain CT, which was also coincided with the high signal region in T2, FLAIR and diffusion-MR images. The MRA of the intracerebral arteries presented no remarkable abnormality. The hemiparesis and impaired consciousness improved partially in the following week. However, she did not fully recover, since aspiration pneumonia and mild generalized inflammation continued. Percutaneous gastrostomy and intravenous hyperalimentation were started to improve her nutrition. The moderate inflammatory state persisted for several weeks. Her blood pressure suddenly fell and she died on June 12. Autopsy showed a mildly brownish and necrotic lesion from the left caudate to the putamen through the internal capsule. There was no liquefaction. On the microscopic examination, the necrosis surrounded by small vessels was consisted of numerous neutrophils and macrophages with pseudohypha and blastospore of candida. Small fragments of fungus were phagocytosed by macrophages. Small abscesses and necrotic foci due to candidiasis were observed in the bladder, kidneys, lungs, myocardium and thyroid gland. In this case, cerebral candidiasis probably occurred via hematogenous dissemination from a primary focus in the urinary tract. The intracerebral arteries revealed rather mild atherosclerotic changes and there was no occlusion by thromboembolism. Intracerebral lesion was diagnosed as candidiasis and there was no cerebral infarction by thromboembolism. If the infection occurred after cerebral infarction, there should not be any inflammatory reaction in the center of necrotic area. There have been few reports of cerebral candidal infection in patients without diabetes mellitus or immunosuppressive conditions. None of them had been diagnosed before death. Caution should be exercised for the presence of systemic candidiasis in elderly patients who are bedridden and with continuous low grade inflammatory reactions.

Anti-glutamic acid decarboxylase antibody is associated with the development of progressive cerebellar ataxia and slowly progressive insulin-dependent diabetes mellitus. Previously, the neurophysiological characteristics of IgG in the cerebrospinal fluid of a patient with anti-glutamic acid decarboxylase antibody-associated progressive cerebellar ataxia and slowly progressive insulin-dependent diabetes mellitus were reported. Using a voltage-gated whole-cell recording technique, it was observed that the IgG in the cerebrospinal fluid of the patient selectively suppressed the inhibitory postsynaptic currents in the Purkinje cells. The patient died from aspiration pneumonia. Postmortem examination showed almost complete depletion of the Purkinje cells with Bergmann gliosis. Therefore, the main cause of cerebellar ataxia observed in this case may be attributed to the near-complete depletion of the Purkinje cells. In this paper, the pathomechanisms underlying Purkinje cell damage are discussed.

The object of this review is to provide the definitions and criteria for diabetic ketoacidosis (DKA) and the hyperglycemic hyperosmolar state (HHS), and convey current knowledge of the causes of permanent disability or mortality from complications of these conditions, of the risk factors for DKA and HHS, and of early indicators and contemporary treatment of suspected cerebral edema. The frequency of DKA at onset of type 1 diabetes mellitus (DM1) varies from 10-70%, depending on availability of health care and frequency of diabetes. At the onset of type 2 diabetes (DM2), DKA occurs in 5-52%. One study reported HHS in approximately 4% of new patients with DM2. Recurrent DKA rates are equally dependent on variability in medical services and socio-economic circumstances, and are estimated to be eight episodes per 100 patient years, with 20% of patients accounting for 80% of the episodes. Mortality for each episode of DKA internationally varies from 0.15-0.31%, with idiopathic cerebral edema accounting for two-thirds or more of this mortality. Other causes of death or disability include untreated DKA or HHS, hypokalemia, hypophosphatemia, hypoglycemia, other intracerebral complications, peripheral venous thrombosis, mucormycosis, rhabdomyolysis, acute pancreatitis, acute renal failure, sepsis, aspiration pneumonia, and other pulmonary complications. Population-based studies from the UK, Australia, the USA, and Canada report cerebral edema incidence in DKA of 0.5-2.0%. Published information does not support the notion that treatment factors are causal in cerebral edema. Younger age, greater severity of acidosis, degree of hypocapnia, and severity of dehydration have been suggested as risk factors in several studies. Bimodal distribution of the time of onset of cerebral edema and wide variation in brain imaging findings suggest the variability and likely multiple causation of the clinical picture. Functional brain scanning has indicated that DKA is accompanied by increased cerebral blood flow suggesting that the predominant mechanism of edema formation is a vasogenic process. A method of monitoring for diagnostic and major and minor signs of cerebral edema has been proposed and tested which indicates that intervention will be required in five individuals to provide early intervention for a single case of cerebral edema. The preferred intervention of mannitol infusion has typically been accompanied by intubation and hyperventilation, but recent evidence indicates outcome is adversely affected by aggressive hyperventilation. The prevention of DKA and HHS at the onset of diabetes mellitus requires a high degree of awareness and suspicion by primary care providers; prevention of recurrent DKA necessitates a diligent team effort.

Dysphagia occurs frequently after a stroke. It is a major problem as patients are at risk of malnutrition and aspiration pneumonia. We aimed to identify the risk factors for and outcome of dysphagia over the first one month after an acute ischaemic stroke. Patients with acute first-ever ischaemic stroke admitted to the medical ward of Hospital Universiti Kebangsaan Malaysia (HUKM) between July 2004 and December 2004 were prospectively examined. Observation was done using pre-defined criteria. Demographic data, risk factors, and type of stroke were recorded on admission. The assessment of dysphagia was made using standardized clinical methods. All patients were followed up for three months. One hundred and thirty four patients were recruited in the study. Fifty-five patients (41%) had dysphagia at presentation. This number was reduced to 29 (21.6%) patients at one month. Logistic regression analysis revealed that age of more than 75 years [OR 5.20 (95% CI 1.89 - 14.30)], diabetes mellitus [OR 2.91 (95% CI 1.07 - 7.91)] and MCA infarct [OR 2.48 (95% CI 1.01-6.14)] independently predicts the occurrence of dysphagia after an acute stroke. Dysphagia at presentation was found to be an independent predictor of mortality at one-month [OR 5.28 (95% CI 1.51-18.45)] post ischaemic infarct. Dysphagia occurred commonly in ischaemic stroke. Advance age, diabetes mellitus and large infarcts were independently associated with the presence of dysphagia. Early stroke mortality can be independently predicted by the presence of dysphagia.

Activating mutations in the Kir6.2 subunit of the adenosine triphosphate-sensitive potassium (KATP) channel is a cause of neonatal diabetes associated with various neurological disorders that include developmental delay, epilepsy, and neonatal diabetes (known together as DEND syndrome). This article reports a girl who developed infantile spasms and early onset diabetes mellitus at the age of 3 months and revealed DEND syndrome with a heterozygous activating mutation in Kir6.2. Infantile spasms with hypsarrhythmia on the electroencephalogram were severe and refractory to steroids. Steroids combined with oral sulfonylurea, a drug that closes the ATP-sensitive potassium channel by an independent mechanism, allowed partial and transitory control of the epilepsy. However, the child still exhibited severe encephalopathy and died of aspiration pneumonia. The role of oral sulfonylurea as an anticonvulsant in DEND syndrome associated with Kir6.2 mutation is discussed.

Obesity is the most common metabolic disease in the world and its prevalence has been increasing over several decades. The World Health Organization (WHO) predicts that, by 2015, around 700 million adults will be obese (at least 10% of the projected global population). This will be a huge health and economic burden with associated increases in diabetes, cardiovascular and musculoskeletal disease, and malignancy. While there has been little focus on the impact of obesity on respiratory disease, there are clear effects on pulmonary function and inflammation which will increase the prevalence and morbidity of lung disease. There is an inverse relationship between body mass index and forced expiratory volume in 1 s. Increases in body weight lead to worsening of pulmonary function. The reasons for this include the mechanical effects of truncal obesity and the metabolic effects of adipose tissue. Obesity is linked to a wide range of respiratory conditions including chronic obstructive pulmonary disease, asthma, obstructive sleep apnoea, pulmonary embolic disease and aspiration pneumonia. It is important for those providing care for people with respiratory disease to appreciate the impact of obesity and to provide appropriate advice for weight reduction. Healthcare planners should consider the impact of obesity for future resources in respiratory care.

Pharmacological treatment of dementia addresses two main clinical features of the disease: cognitive deterioration with predominantly memory loss and behavioural and psychological symptoms (BPSD). While cholinesterase inhibitors are recommended in an attempt to delay memory loss and disability, what should be considered the most appropriate pharmacological treatment for BPSD has remained questionable. Antipsychotic medications, conventional and atypical agents, have been increasingly utilized in clinical practice but only a small number of clinical studies have investigated their relative cost-benefit ratio. This review focuses on the safety of atypical and conventional antipsychotics when used in patients with BPSD. Overall, atypical and conventional antipsychotics are associated with a similarly increased risk for all-cause mortality and cerebrovascular events. Relative to atypical agents users, patients being treated with conventional antipsychotics have an increased incidence of cardiac arrhythmias and extrapyramidal symptoms. Conversely, users of atypical antipsychotics are exposed to an increased risk of venous thromboembolism and aspiration pneumonia. Also, metabolic effects (i.e. increased risk of diabetes, weight gain) have consistently been documented in clinical studies with atypical antipsychotics, although this effect tends to be attenuated with advancing age and in elderly patients with dementia. Antipsychotics, both conventional and atypical, should be used with caution only when nonpharmacologic approaches have failed to adequately control BPSD. More effective interventions are necessary to improve postmarket drug safety in vulnerable populations.
