The prevalence of dementia disorders, cobalamin and/or folate deficiency as well as gastritis increases with age. To investigate whether there is an association between these conditions, plasma homocysteine (Hcy), serum methylmalonic acid, serum cobalamin and blood folate concentrations were measured. Gastritis was indirectly diagnosed by measuring serum antibodies against H,K-ATPase, HELICOBACTER PYLORI and intrinsic factor, using enzyme-linked immunosorbent assays. The studied groups consisted of 47 patients with Alzheimer's disease (AD), 9 with AD pathology in combination with additive vascular lesions, 59 with vascular dementia, 8 who were cognitively impaired, and 101 control cases. Plasma Hcy concentrations were significantly elevated in the dementia groups, with the highest levels in patients with vascular pathology. We conclude that hyperhomocysteinemia is a common finding in patients with dementia disorders of different etiologies. The markers for gastritis did not contribute to an elucidation of a possible connection between this condition, dementia disorders, or cobalamin/folate deficiency.
BACKGROUND: Serious sepsis and major blunt trauma have adverse effects on body composition, physiological function and psychological state. The effect of severe acute pancreatitis on these groups of variables has not yet been reported. METHODS: We have studied the effect of predicted severe acute pancreatitis (admission APACHE II score > or = 6) on body fat and mid arm muscle circumference (assessed by dual-energy X-ray absorptiometry and anthropometry), respiratory function (measured by spirometry and vitalography), voluntary muscle function (measured by hand dynamometry) and psychological state (measured by use of the hospital anxiety and depression score and visual analogue scale for fatigue) on admission, and three and seven days thereafter. RESULTS: The median APACHE II score of the 15 patients (7 men) in this study was 10 (6-13). The patients showed significant improvement in respiratory function (FEV1 1.3, 1.6, 2.3 litres/s, p < 0.01; FVC 1.5, 2.0, 2.9 litres, p < 0.01; PEFR 304, 372, 409 litres/min, p = 0.01 but no change in voluntary muscle function (210, 205, 213 N, p = 0.41) over the 7-day study period. Psychological state improved in terms of fatigue (2.4, 4.2, 7.0, p < 0.01) and depression (6, 9, 4, p = 0.12) but not in anxiety (8, 6, 7, p = 0.07). Body fat measured by DEXA (17.3 kg on admission, 16.7 kg on day 7, p = 0.13) and the mid upper arm muscle circumference (262, 248, 251 mm, p = 0.10) did not change implying that energy and nitrogen balance over the 7-day study period was achieved. CONCLUSION: Predicted severe acute pancreatitis has an adverse effect on respiratory function and psychological state similar to that observed in serious sepsis. Improvement in these variables is apparent over 7 days of effective treatment. Further research is indicated to examine the effect of nutritional support on these variables.
A case of rupture of an intra-aortic balloon is reported. The rupture, noted 34 hours after insertion of the balloon, was caused by perforation by an atheromatous plaque. The patient exhibited no adverse effects from the episode.
Twenty children (mean age 3.25 years) with congenital cyanotic heart disease undergoing modified left Blalock-Taussig (BT) shunt were studied. The mean follow-up period was 9.5 months (range 6 months to 1 year). The shunt was performed for cyanotic spells in 15 (75%) and hypoplastic pulmonary arteries in 5 (25%) patients. There were no immediate or late complications. None had cyanotic spell after the shunt. The mean arterial oxygen saturation improved from 66.47 +/- 11.9 to 76.97 +/- 8.16% (p = 0.0003) and mean hematocrit decreased from 51.55 +/- 9.5 to 46.5 +/- 9.7 (p = 0.002) after the shunt. The left atrial systolic volume and left ventricular diastolic volume also increased significantly following the shunt (from 15.82 +/- 6.37 to 20.83 +/- 8.91 ml p = 0.006 and from 36.13 +/- 16.08 to 41.08 +/- 20.07 ml (p = 0.01) respectively. There was significant growth of main, right and left pulmonary arteries and pulmonary valve annulus after the procedure.
2 cases of unruptured aneurysm of the sinus of Valsalva are presented. Both the patients had involvement of the right sinus of Valsalva. One of the patients had associated systemic lupus erythematosus (SLE). Such an association has not been described in the literature. Clinical, echocardiographic and the angiographic features have been discussed and literature reviewed.
