1/13. Chronic subdural hematoma with vasogenic edema in the cerebral hemisphere--case report.An 80-year-old male with a history of hypertension presented with chronic subdural hematoma manifesting as progressive consciousness disturbance and left hemiparesis. T1-weighted and fluid attenuation inversion recovery (FLAIR) magnetic resonance imaging showed a fresh hematoma in the right subdural space with a midline shift of 15 mm. FLAIR and diffusion-weighted imaging showed a hyperintense area in the right paraventricular white matter compressed by the hematoma. Apparent diffusion coefficients (ADCs) corresponding to the hyperintense area in the central area of the affected cerebral hemisphere on FLAIR images were measured before and one month after the operation. The motion probing gradient was applied in the right-left direction to the body axis. Since the central area in the cerebrum includes nerve fibers perpendicular to the direction of the gradient, the measured ADC appeared to be anisotropic. Preoperative ADC in the right paraventricular white matter was anisotropic and greater than in age-matched normal subjects, so the edema was identified as the vasogenic type. The edema in the right paraventricular white matter resolved promptly with improvement of the midline shift and normalization of the ADC.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
2/13. Usefulness of magnetic resonance spectroscopy for diagnosis of hepatic encephalopathy in a patient with relapsing confusional syndrome.magnetic resonance spectroscopy allows the assessment of several metabolites in brain tissue. In patients with hepatic encephalopathy, this technique shows a rise in glutamine and a decrease in myoinositol in brain tissue. However, the role of magnetic resonance spectroscopy in the diagnosis of hepatic encephalopathy is not known. We report the case of a patient with a relapsing confusional syndrome who underwent magnetic resonance spectroscopy. Previously, hepatic encephalopathy was ruled out because of the negative results of a transjugular liver biopsy and normal hepatic venous pressure gradient. The results of magnetic resonance were characteristic of hepatic encephalopathy. Abdominal computed tomography demonstrated large portosystemic shunts associated with cirrhosis of the liver. This case shows that magnetic resonance spectroscopy is an useful technique for the diagnosis of hepatic encephalopathy in selected cases, such as those without clinical signs of cirrhosis and/or large portosystemic shunts.- - - - - - - - - - ranking = 1.3167541552582keywords = pressure (Clic here for more details about this article) |
3/13. Posterior leukoencephalopathy in a girl with acute haemorrhagic leukoencephalitis.In children, posterior leukoencephalopathy is frequently associated with hypertensive encephalopathy, anticancer chemotherapy, treatment with immunosuppressive drugs in patients with organ transplantation, transfusion or human immunodeficiency virus infection. Posterior leukoencephalopathy in these children appears as a complicating illness and resolves once precipitating factor (e.g. cancer chemotherapy) is removed. Here we are reporting a fatal case of acute haemorrhatic leukoencephalitis in a 13 year old girl, imaging abnormalities are also suggestive of posterior leukoencephalopathy. Posterior leukoencephalopathy in our patient possibly, is a part of post-infectious haemorrhagic leukoencephalitis, rather than because of ischaemia or cerebral oedema secondary either to abrupt increase in blood pressure or following administration of immunosuppressive drugs.- - - - - - - - - - ranking = 7.1195936455837keywords = blood pressure, pressure (Clic here for more details about this article) |
4/13. confusion as the presenting manifestation of vertebral osteomyelitis: a case report.A 44-year-old patient presented with increasing confusion. He was first diagnosed as having intermittent pressure hydrocephalus but a further evaluation showed CSF pleocytosis and hypoglycorrhachia. Five weeks later, his physical examination was unrevealing. Nuclear imaging techniques were conflicting, with negative gallium- and indium-labelled white blood cells scans but a Tc scan pointing towards a vertebral infection. A well-demarcated lesion in the T9 vertebral body, demonstrated by CT scan, confirmed the diagnosis of vertebral osteomyelitis. Although we were unable to recover the causative organism, antibiotic treatment for presumed staphylococcal osteomyelitis resulted in full recovery. This case indicates that vertebral osteomyelitis may cause significant meningeal inflammation even in the absence of epidural or subdural abscess. We recommend that in patients with meningitis without a clear etiology vertebral osteomyelitis should be considered and pursued with CT scannings of the vertebrae, a procedure that can yield positive findings even when other scanning modalities are negative.- - - - - - - - - - ranking = 1.3167541552582keywords = pressure (Clic here for more details about this article) |
5/13. A 73-year-old man with confusion, fever, and positive MPO-ANCA.A 73-year-old man was admitted to the hospital because of progressive lethargy and fever. He had a history of hypertension since the age of 40, and was diagnosed as having a testicular tumor at the age of 50. On admission, he looked pale and stuporous. Laboratory examination revealed microscopic hematuria. The erythrocyte sedimentation rate was 110 mm/hr, and the serum CRP was 14.3 mg/dl. The titer of myeloperoxidase-antineutrophilic cytoplasmic antibodies (MPO-ANCA) was higher than 1:1000. On the sixth hospital day, he required ventilatory assistance because of aspiration pneumonia and was connected to a respirator. He was treated with intravenous corticosteroids, to which he responded in the short term with resolution of the fever and decrease in the serum CRP level, however, the consciousness disturbance persisted and the fever recurred soon thereafter. He developed gross hematuria and the renal function deteriorated. He eventually died of renal failure and pulmonary hemorrhage. Although his clinical course and laboratory findings were consistent with those of microscopic polyangitis, the pathological diagnosis was crescentic glomerulonephritis with no evidence of vasculitis.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |

7/13. Type II diabetes: some problems in diagnosis and treatment.This case is a rather typical presentation of a patient with mild, type II diabetes. His case illustrates some of the pitfalls in the dietary management of diabetes, in treating the glucose abnormality and hypertension, and in diagnosing the mental obtundation that can occur in type II disease. This patient inverted question marks glucose abnormality can probably be treated adequately with a normal- or low-calorie diet that is appropriately high in carbohydrates and low in fats. His hypertension must be treated adequately, preferably with lower doses of diuretics or, if other drugs are necessary, one other than a beta-adrenergic blocking drug. Clearly, his cholesterol should be treated too, but the high-carbohydrate, low-fat diet now prescribed for diabetics will probably be adequate to reduce this risk factor for cardiovascular disease. Finally, the last major risk factor for cardiovascular disease, namely smoking, should unquestionably be removed.- - - - - - - - - - ranking = 2keywords = hypertension (Clic here for more details about this article) |
8/13. Percutaneous ultrasonic lithotripsy: choice of irrigant.Extravasation of glycine irrigant during percutaneous ultrasonic lithotripsy has caused a transurethral resection syndrome consisting of hypertension, confusion and hyponatremia. With a rabbit model this complication is recreated with the intraperitoneal instillation of 1.5 per cent glycine solution tagged with 14carbon-glycine. Significant quantitative absorption of glycine into blood and other organs is demonstrated. A review of the literature reveals few guidelines as to the choice of irrigant for intrarenal endoscopy. Since this procedure involves no electric current it is suggested that physiological saline rather than glycine be used for ultrasonic stone disintegration.- - - - - - - - - - ranking = 1keywords = hypertension (Clic here for more details about this article) |
9/13. Sexual intercourse as a precipitating factor of transient global amnesia.A Japanese female case of transient global amnesia (TGA), who developed an amnesic episode after sexual intercourse, is reported. The mechanism of how TGA in the present case is precipitated by sexual intercourse could be explained by the elevated blood pressure during sexual intercourse that drops rapidly, causing a temporal ischemia in the distribution of the basilar artery. Furthermore, the importance of sexual intercourse as a precipitating factor of TGA is stressed.- - - - - - - - - - ranking = 7.1195936455837keywords = blood pressure, pressure (Clic here for more details about this article) |
10/13. Early, fatal disseminated intravascular coagulation in a patient with 60 per cent burns.A 23-year-old, previously fit and healthy young man was admitted to the West Midlands Regional burns Unit at the Birmingham Accident Hospital, with 60 per cent body surface area burns and smoke inhalation. On arrival, he was briskly tachycardiac, hypotensive and disorientated. He was admitted to the intensive care unit, intubated and started on intermittent positive pressure ventilation. Despite prompt commencement of resuscitation and the infusion of enormous volumes of colloids, the patient remained oliguric. He soon developed severe haemorrhage from his gastrointestinal, urinary and respiratory tracts. He required several units of blood, but was persistently hypotensive. His condition deteriorated rapidly despite intensive supportive measures. He developed metabolic acidosis, refractory hypotension and died anuric, 20 h later. The post-mortem examination showed the presence of disseminated intravascular coagulation and adult respiratory distress syndrome.- - - - - - - - - - ranking = 1.3167541552582keywords = pressure (Clic here for more details about this article) |
