    ABSTRACT: Schizophrenia as severe mental disorder is characterized by a disintegration of the process of thinking and of emotional responsiveness whereas the underlying mechanisms of schizophrenia are complex and still discussed. The objective of this study is to find out if patients with schizophrenia and their healthy first-degree relatives have abnormal autonomic nervous system (ANS) activity by measuring cardiac indices as QT variability index (QTVI). Moreover, it is useful to study if ANS dysfunction could play an important role in schizophrenia and if abnormal functioning could be retrieved by patients' healthy first degree relatives. Also, a parallel experiment monitored QTVI in healthy controls before, during and after a new complex stress test named Mannheim Multicomponent Stress Test (MMST). As QT variability analysis results were not significantly different during MMST versus normal state, we concluded that short-term stress has no fundamental impact on ECG morphology in healthy subjects. However, patients with schizophrenia revealed an increased QTVI that indicates structural changes of ECG morphology in those patients. These findings were obviously independent from the findings regarding to healthy subjects under stress and healthy subjects (basic measurement of 30min).

    ABSTRACT: A complex goal in biomedical information technology today is the design and implementation of telemedicine and e-health solutions, which provide (chronic) patients and elderly people services that can enhance their quality of life. We used wireless sensor network technology, low-power integrated embedded systems and wireless communications, which have enabled us the design of low-cost, miniature, precise and intelligent physiological sensor modules. These modules are capable of measuring, processing, communicating one or more physiological parameters, and can be integrated into a wireless personal area network (WPAN). We have designed, deployed, produced and tested both hardware and software medical sensors for WPAN, dedicated to vital signs acquisition, processing and transmitting, as well as the whole telemedical system for these physiologic parameters monitoring in real time. This paper is dedicated to the most complex Romanian telemedical pilot project, TELEMON, that has as goals the design and implementation of a system for automatic and complex telemonitoring, everywhere and every time, in (almost) real time, of the vital signs of persons with chronic illnesses, of elderly people, of those having high medical risk and of those living in isolated regions. The final objective of this pilot project is to enable personalized telemedical services, and to act as a basis for a public service for telemedical procedures in Romania and abroad.

    ABSTRACT: Therapeutic adherence represents the extent to which the patient's behavior follows medical recommendations. It is a complex process that strongly influences the quality of life of the each and everyone. We performed a retrospective study that included 126 very old patients (≥ 80 years old). Patients' data were recorded in a database that contained demographic and clinical data and information about patient's current medication. Information about therapeutical adherence was collected for each person by way of a questionnaire, which consisted in verifying their knowledge about their diet and medication and comparing it with information from past medical records or family members. We found several factors that influence adherence to treatment: living in the urban area, the number of pills prescribed by the general practitioner and a strong familial and financial support. Fighting non-adherence should rely upon two complementary directions: the multidisciplinary medical approach and the telemonitoring and e-health systems.

    ABSTRACT: Introduction Falls are frequently encountered in older people and often may be caused by orthostatic hypotension that has several etiologic factors. Objective of the research was to apply a postural exercise program in older patients aiming at reducing postural hypotension that was not due to side effects of medicines. Materials We included 416 patients, age range 65–85, divided into two age-matched groups, both presenting postural hypotension: Study Group - 195 subjects that followed specific postural exercises program and Control Group - 221 subjects without this program. Exercises were performed 15 minutes three times daily for one month. We excluded patients with cognitive impairment, on medication that could induce postural hypotension, with severe heart conditions, severe joint diseases and stroke sequelae that could interfere with program. Results At inclusion t-test for independent samples showed significant orthostatic reduction in Systolic blood pressure for both Study and Control Group: t= –4.370; statistical significance p<0.001; confidence level 95%; confidence interval: –8.2148 and –3.1886. After 30 days of postural exercises program we noticed a significant reduction in Systolic blood pressure difference between orthostatic and recumbent position in Study Group patients (t-test for paired samples: t= –3.270, p<0.005), but not in Control Group (t=1,526, p=0.171). Moreover, incidence of falls was significantly lower (p<0.001) in Study Group as compared to Control. Study Group subjects tolerated better standing and walking. Conclusion The program could act by re-training carotid sinus baroreceptors through a postural stimulation and this could reduce the risk of falls in older patients.

    ABSTRACT: Introduction We evaluated effects of diabetes mellitus on cognitive function in non-demented older patients. Methods We included 537 older patients with diabetes mellitus consequently admitted to our departments. Age range: 65 - 95 years, mean 80; 73% women, 27% men. Three age groups were considered: young-old (65-74 years), old-old (75-84 years), very-old (>84). We excluded patients with past medical history of stroke, dementia, depression (score of >/=8 on the Short version of Geriatric Depression Scale). Cognitive function was evaluated using MMSE, Clock-drawing Test, Five Words Test and Stroop Test (score >42 normal). HbA1c assessed long-term response to anti-diabetic treatment (>7% -abnormal). Results Irrespective of age-group, past medical history of diabetes mellitus >10 years correlated with higher prevalence of mild cognitive impairment (correlation coefficient r=0.86). Very-old group had better scores on cognitive tests, but maximum glucose levels were lower, possibly due to selection effect. Significant difference was noticed between scores on Five Words Test and Stroop Test in patients with HbA1c >10% as compared to those with HbA1c < 7% (p<0.005) irrespective of age-group and gender. Conclusions Poor control of diabetes mellitus is a significant risk factor for cognitive impairment in elderly. Moreover, diabetes mellitus itself makes these patients prone to cognitive impairment possibly due to macro- and microvascular complications of this metabolic disease. A systematic screening of cognitive function needs to be performed in elderly diabetics to establish an early diagnosis of cognitive impairment and start adequate and timed therapy to slow down progression of cognitive disorder. - DOI: http://dx.doi.org/10.1016/j.eurger.2012.07.360

    ABSTRACT: Right heart infective endocarditis in an elderly patient with no previous known risk factors is a very rare situation (even if subacute infective endocarditis has the same chance of occurrence at either a young person, or an elderly patient). We present the case of a 75-years old patient, with no previous cardiac history, addressed to our clinic with nonspecific septic symptoms associated with an edematous syndrome. The patient was treated for right heart valve infective endocarditis; a particularity may be the fact not all Duke criteria were respected. Iatrogeny was involved, our patient having administered a 7-day antibiotic treatment before hospital addressing. The therapeutic probe was positive: excellent evolution under treatment. Few cases of infective endocarditis of the tricuspid valve were reported worldwide, in which the source of infection was unknown in about 80% of cases. In two pediatric cases reported, tricuspid endocarditis was caused by Staphylococcus aureus septicemia following upper respiratory infection. This may also occur in adult cases. Further investigations should be carried out in the future to elucidate the source of infection. Isolated right-sided endocarditis should be included in the differential diagnosis of patients with febrile syndrome, respiratory symptoms and predisposing disease, even when they do not have a pacemaker and are not intravenous-drug users (IVDU).

    ABSTRACT: The 21st century's demographic and epidemiologic perspectives suggest an absolute and percentual increment of elderly population. In the same time the prevalence of heart insufficiency increases with advanced age, which transforms heart failure in a true challenge for health insurance system. This new dimension of the problem resides in the increment of heart insufficiency's prevalence and in the high costs of medical care of these patients. Heart failure's medical costs are high not only due to the necessity of compensating the cardiac function but also due to the necessity of treating the etiology, the risk factors and the co-morbidities with cardiac side effects. Elderly patients usually have a low therapeutic compliance and an important number of iatrogenic reactions mainly due to poly-medication, poly-pathology and cognitive and physical deficiencies, which need special measures of therapeutic education for the patient and family and medical survey, probably best in a nursing house; all these elements increase significantly the cost, which is almost double than the cost for cancer. The prophylaxis in heart insufficiency means an extremely efficient management of entire cardiac pathology in order to delay the moment of heart failure. In elderly patients, the treatment in heart insufficiency is difficult not due to hospital treatment of decompensation episodes but due to low therapeutic compliance at home. We need special programs to ensure medical education of the patient and the family/caregiver in order to avoid iatrogenic pathology and to ensure therapeutic efficiency.

    ABSTRACT: Discussions about the impact of iatrogeny over general health were avoided and neglected for a very long time. It was brought to medical interest due to recent studies concerning therapeutic compliance, patient's medical education and acute awareness of ethical implications of medical activities. Even if iatrogeny was always present in medicine, we realized but recently the dimensions and the necessity of a coherent and systematic approach of this problem. Iatrogenic pathology in elderly population has even a bigger impact due to conjugation of two major demographic phenomena: an absolute and percentage increase of elderly population parallel with an increase of prevalence of iatrogenic pathology with age. That's why iatrogeny in elderly becomes a major health problem, unfortunately often ignored, neglected and even obscured inspite of well-recognized impact over duration and quality of patient's life as well as over the cost of medical assistance.

    ABSTRACT: Neuropsychiatric systemic lupus erythematosus (NPSLE) has become a popular term designing all neurological and psychiatric complications in patients with systemic lupus erythematosus (SLE). It occurs in up to two thirds of all SLE patients and it covers a vast array of disorders ranging from peripheral neuropathy to stroke, psychosis, and dementia. Mechanisms associated with the pathogenesis of NPSLE include anti-neuronal antibodies, antiphospholipid antibody associated thrombosis, emboli from cardiac source and, rarely, vasculitis by immune complex depositions. Although the most common manifestations is cognitive dysfunction (50%), NPSLE may also present itself as peripheral neuropathy (15%), psychosis (10%), or other central nervous system abnormalities (stroke, organic brain syndrome, seizures). In lupus patients, one should always look for secondary causes of the neuropsychiatric manifestation, including infection, toxic metabolic abnormalities, and hypertension. We present two cases of SLE, which developed neuropsychiatric manifestations.

    ABSTRACT: Oxidative stress is the result of the imbalance between pro-oxidant and antioxidant factors. The participation of oxidative stress in atherosclerosis (ATS) is reflected by lipid peroxidation which is a process initiated and maintained by oxygen reactive species generated by the aterogenic cells themselves. The endothelial aggression in ATS is accompanied by endothelial dysfunction, which is due to the neutralization of nitric oxide by superoxid anion. The key role in the onset and the development of the ATS lesions belongs to oxidated LDL-cholesterol that influence at different levels and by several mechanisms the ATS process. The neutralization of the toxic effects of free radicals is due to the endo and exogen antioxidant systems. It appears that the individual antioxidant status is influenced by environmental factors as well as by a genetic determinant. The antioxidant therapy, which is controversial at the moment, represents an associated therapy in endothelial dysfunction from ATS.

    ABSTRACT: We present the case of a female patient with a chronic hypersideremic anemia associated with digestive and neurological symptoms, with a long time ignored toxic history. The diagnose was based on very high levels of lead in serum and urine, very high levels of D-aminolaevulinic acid in the urine, and the presence of basophilic stippling of erythrocytes in the smear of the patient. Lead intoxication was due to ingestion of home-made alcohol (domestic devices made from lead mixtures) and of yogurt preserved in lead-glazed mugs.
