Evaluation of depression in patients with alzheimer's disease according to the location of medical care

The objective of the study was to assess the severity of depression and to assess the level of self-sufficiency of patients with Alzheimer's disease, with particular emphasis on the place of residence and level of education. The study covered 90 people diagnosed with Alzheimer's disease. All respondents were persons over 65?years of age and residents of cities with a population over one-hundred thousand. The research method based on this work is the author's own questionnaire, the Zung Self-Rating Depression Scale (ZSDS) about depression and the Karnofsky Performance Scale Index (KPSI) for assessment of a patient's self-sufficiency. Regardless of residence, patients with Alzheimer's disease displayed signs of mild or moderate depression (100% in social welfare homes and hospital patients and 60% in those with caregivers at home). Patients with Alzheimer's disease have an unsatisfactory salary in social-economic terms. In those with Alzheimer's disease, quality of life is best for those in family homes under the care of their immediate family. People with a vocational education were the largest group of people diagnosed with Alzheimer's. Patients at home and in the hospital had a higher level of physical activity, but most patients in the hospital needed regular medical care, as did patients in social welfare homes.     

Bullous pemphigoid: Etiology,pathogenesis, and inducing factors: Facts and controversies

The term pemphigoids includes a group of autoimmune bullous diseases characterized by subepidermal blistering. Bullous pemphigoid (BP) is not only the most common disorder within the pemphigoid group, but also represents the most frequent autoimmune blistering disease in general.     

Chronic liver disease in transfusion-dependent thalassaemia: hepatitis B virus marker studies.

The systematic screening of 253 children with transfusion-dependent homozygous beta-thalassaemia revealed a high incidence of hepatitis B virus markers. The highest frequencies of hepatitis B surface antigen (HBsAg) and antibody to hepatitis B core antigen (anti-HBc) were found in the group of patients with the smallest number of transfusions, while the highest frequency of antibody to hepatitis B surface antigen (anti-HBs) was detected in the patients who had had the largest number of transfusions. Follow-up of these patients showed (a) a high incidence of acute hepatitis B, which was mainly subclinical; (b) normal hepatitis B surface antigen clearance and normal antibody to hepatitis B surface development; and (c) a high frequency of increased transaminase values for over six months. In all the subjects with persistently high transaminase, histological examination revealed chronic persistent hepatitis or chronic active hepatitis. Apart from two cases of chronic active hepatitis with no B virus markers, and two cases of chronic persistent hepatitis with HBsAg and anti-HBc in the serum, all these subjects were anti-HBs positive but HGsAg and anti-HBc negative.     

Growth hormone receptor polymorphism and the effects of pegvisomant in acromegaly

Background    Sensitivity to pegvisomant therapy is highly variable in patients with acromegaly but determinants of this variability are still unknown. Lack of exon 3 (d3-) of the growth hormone (GH) receptor (GHR) has been associated with increased biological activity of GH. Objective    To assess whether the presence of d3-GHR haplotype may have a role in predicting dose regimen and response to pegvisomant in acromegaly. Design    Case series. Setting    Institutional referral center at a tertiary care hospital. Patients    Ninenteen acromegalic patients with active disease after unsuccessful neurosurgery and somatostatin analog therapy. Measurements    before and 1, 3, 6 and 12 months after treatment with pegvisomant, IGF-I; GH receptor genotype, determined from peripheral blood by polymerase chain reaction. All patients started treatment with pegvisomant at 10 mg/daily and then increased the dose, according to a fixed schedule, during a 12-month follow-up until normalization of IGF-I levels. Results    d3-GHR patients required a significant lower dose of pegvisomant and shorter treatment time to normalize IGF-I. Conclusion    the GHR genotype could be useful in predicting dose and individual response to pegvisomant in acromegaly.     

Predictors of persistence of functional mitral regurgitation after cardiac resynchronization therapy: Review of literature

Functional mitral regurgitation is a common finding among heart failure patients with ischemic and non-ischemic dilated cardiomyopathies. The presence of moderate or severe mitral regurgitation is associated with higher morbidity and mortality. Heart failure patients meeting electrocardiogram and left ventricle function criteria are good candidates for cardiac resynchronization therapy, which may reduce the degree of functional mitral regurgitation in the short and long term, specifically targeting myocardial dyssynchrony and inducing left ventricle reverse remodeling. In this article, we analyze data from the literature about predictors of mitral regurgitation improvement after cardiac resynchronization therapy implantation.     

Corticosteroid-sparing effect of intravenous immunoglobulin therapy in patients with pemphigus vulgaris

BACKGROUND: Pemphigus vulgaris (PV) is a rare, potentially fatal autoimmune mucocutaneous blistering disease. The prolonged use of systemic corticosteroids, though clinically effective in high doses, can result in multiple debilitating adverse effects. Immunosuppressive agents, used as adjuvants and as corticosteroid-sparing agents, are not effective in all patients and are contraindicated in some. Therefore, alternative treatment modalities are needed to provide effective control of PV in such patients. OBJECTIVE: To demonstrate the corticosteroid-sparing effect of intravenous immunoglobulin (IVIg) therapy in patients with moderate to severe PV. DESIGN: A retrospective analysis in a cohort of 15 patients with moderate to severe PV who were treated with IVIg therapy. All 15 patients were corticosteroid dependent, and the use of other systemic conventional immunosuppressive agents was contraindicated. The patients were followed up over a mean period of 6.2 years. SETTING: Ambulatory tertiary medical care facility of a university-affiliated hospital. INTERVENTION: All 15 patients received an IVIg dose of 1 to 2 mg/kg per cycle. MAIN OUTCOME MEASURES: The following information was documented in each of the 15 patients before and after the initiation of IVIg therapy: total dosage and total duration of prednisone therapy and number of relapses. Also, the highest dosage and adverse effects of prednisone therapy, as well as the total duration of observation, were recorded. RESULTS: All 15 patients had a satisfactory clinical response to IVIg therapy. The use of systemic prednisone was gradually discontinued over a mean period of 4.3 months. A statistically significant difference was noted in the total dose of prednisone (P =.004), total duration of prednisone therapy (P =.003), and number of relapses (P<.001) before and after the initiation of IVIg therapy. CONCLUSIONS: Intravenous immunoglobulin therapy has a demonstrable corticosteroid-sparing effect. It is a safe and effective alternative treatment modality in patients with PV who are dependent on systemic corticosteroids or who develop significant adverse effects as a result of their use.     

The Nephropathy of Experimental Hepatosplenic Schistosomiasis

The glomerular lesions induced in 10 chimpanzees infected with variable numbers of Schistosoma japonicum cercariae were studied by means of light and electron microscopy and fluorescent antibody technic. Ten animals served as controls; 5 were uninfected and 5 were only lightly infected. The animals were observed for periods ranging from 3 to 17 months, and by the time of sacrifice, all had developed advanced liver fibrosis. In general, the degree of glomerular injury was related to infection intensity and degree and duration of portal liver fibrosis. Some animals had terminal BUN elevation and slight proteinuria. By light and electron microscopy, in the initial stages, only part of the glomeruli were involved and exhibited mesangial matrix expansion and mesangial cell proliferation with intracellular hyaline droplets. At later stages, a larger number of glomeruli were affected and exhibited diffuse hypercellularity, glomerular basement thickening, mesangial sclerosis and less often, focal necrosis, crescent formation, synechiae and global hyalinization. In addition, there were discrete electron-dense deposits localized in the mesangial area in some glomeruli. Immunofluorescent studies utilizing antisera to chimpanzee γ-globulin and complement (C3) and to human properdin disclosed only faint deposits of C3, apparently in mesangial areas. The association of hepatosplenic schistosomiasis and nephropathy, the possible role of schistosomal antigen and the mechanism(s) of such glomerular injuries are reviewed and compared with the disease in humans and other host species infected with Schistosoma.     

A pilot study of capsule endoscopy after a standard meal for the detection and grading of oesophageal varices in cirrhotic patients

Background

Capsule endoscopy has been proposed as an alternative to fibreoptic endoscopy for oesophageal varices evaluation in cirrhotics. However, it shows only moderate sensitivity compared to fibreoptic endoscopy.

Aim

To compare post-meal capsule endoscopy to fibreoptic endoscopy, based on the hypothesis that meal-induced increase of portal pressure can enhance its sensitivity.

Methods

Twenty-five patients were submitted to fibreoptic endoscopy and, after a standard meal, capsule endoscopy.

Results

Post-meal capsule endoscopy detected varices in the 18 patients in whom fibreoptic endoscopy detected varices plus 3 more subjects (sensitivity 100%, specificity 70%); large varices in the 4 patients in whom fibreoptic endoscopy graded varices as large, plus 5 more subjects; red markers in the 5 patients in whom fibreoptic endoscopy detected red markers, plus 3 more subjects. High-risk varices were identified in 11 patients by post-meal capsule endoscopy and in 10 by fibreoptic endoscopy (sensitivity 100%, specificity 93.8%).

Conclusions

Post-meal capsule endoscopy identified more varices, large varices and red markers than fibreoptic endoscopy. The two methods detected similar proportions of high-risk varices. These data suggest that a standard meal can enhance the sensitivity of capsule endoscopy in the detection and grading of oesophageal varices in cirrhotics.
