Furthermore there is no possibility that the Occupational Diseases Committee will recommend recognition of the claim cheap 50mg imuran with visa spasms on left side of abdomen. This is because the solider has not experienced any exposures that solely or mainly caused his mental illness cheap imuran 50mg on-line spasms spinal cord injury. The prison service and the police Example 6: Recognition after work as a prison officer A prison officer was for several years employed in a prison where the work became more and more stressful cheap imuran 50mg visa quick spasms in lower abdomen, i. It appeared from the medical specialists certificate that the diagnosis was posttraumatic stress disorder. The prison officer was for quite some time exposed to severe threats and other violent, mentally stressful incidents in his work as a prison officer, being in contact with psychologically very stressful prisoners. Furthermore he had developed symptoms consistent with posttraumatic stress disorder. Example 7: Recognition after work as a prison officer The injured person had for many years worked as a prison officer, i. Subsequently he was employed in a prison where he was exposed to violence, hand grenade attacks and shooting with automatic weapons. The injured person was exposed to threats of violence and actual violence as well as exceptionally severe mental stresses. He subsequently developed symptoms consistent with posttraumatic stress disorder, and there is good correlation between the mental disease and the exposures in the workplace. The police officer, as part of his work in the police force, was called out to a number of incidents involving violent deaths as well as a fatal shooting incident. Example 9: Claim turned down work as a prison officer A 50-year-old man had worked for 20 years as a prison officer. In this employment he was exposed to daily conflicts with the inmates, was threatened with broken glass and knives, and was kicked in the face in connection with an arrest. Well over 4 years after leaving the job he had symptoms of a mental disease with nightmares and emotional complaints. The medical specialist established symptoms of a moderate traumatic stress condition. The claim does not qualify for recognition on the basis of the list, and there are no grounds for submission of the claim to the Committee. The prison officer had psychologically very stressful experiences from his work, but only developed mental symptoms 4 years after cessation of work. Therefore there is no good time correlation between the exposure and the development of the disease. Healthcare work Example 10: Recognition after work as a home help A home help had for some years worked with a female patient who was paralysed on one side. The patients spouse behaved very aggressively and threateningly in the home helps presence, hit and kicked at objects and knocked a fist into the wall, right above the head of the home help. The medical specialists certificate stated the diagnosis of posttraumatic stress disorder. In her work, the home help experienced instances of a very threatening and aggressive behaviour on the part of a clients husband. Against the background of the description of the incidents it must seem likely that she had reason to feel sincerely and personally threatened. Furthermore she had developed symptoms of posttraumatic stress disorder in relevant time correlation with the exposure. Example 11: Recognition after work in an institution for the mentally handicapped A young woman was for some years employed in a 24-hour institution for the mentally handicapped and had for one year been exposed to four violent assaults where she was kicked and beaten. The woman was exposed to several violent assaults in the workplace, being kicked and beaten. Example 12: Claim turned down exposure to complaints (nurse) A nurse who was employed in municipal home care received complaints from relatives in connection with supervision of an elderly man. In that connection she was called in to a meeting with management and received a reproof. Nor was it any exceptionally threatening or catastrophic exposure that might have led to a posttraumatic stress disorder. Therefore the claim does not meet the requirements to diagnosis or relevant exposure. At the same time it must be deemed to be futile to submit the claim to the Occupational Diseases Committee. Example 13: Claim turned down work in a psychiatric hospital and nursing home (healthcare assistant) A healthcare assistant working permanent night shifts in a psychiatric hospital and a psychiatric nursing home developed, according to the medical specialists assessment, symptoms of a posttraumatic stress disorder. The exposure was depicted in general terms, and neither the healthcare assistant nor others were able to give an account of concrete and specific, mentally stressful episodes or courses of events where she had been directly involved or exposed. The claim does not qualify for recognition on the basis of the list as, according to the assessment made by the National Board of Industrial Injuries, it was not a posttraumatic stress disorder. There is no description of any concrete and relevant, exceptionally threatening or catastrophic exposures that might lead to the disease. Education Example 14: Recognition after work as a teacher to children with development problems A teacher was employed in a school where the children had development problems and learning disabilities. He was a personal teacher to a big autistic boy with recurrent extroverted and aggressive behaviour. The boy had repeatedly hit the teacher, who furthermore was exposed to various accusations from the parents. It appeared from the medical specialists report that he had developed symptoms of mental illness. In connection with the work the teacher had been exposed to repeated incidents of violence from a big, extroverted, autistic boy as well as accusations from the parents. The case furthermore became the object of media coverage, and the injured persons name was publicised. In correlation with this he developed clear symptoms of posttraumatic stress disorder. Serious sexual accusations or offences Example 15: Recognition after judgement and later acquittal of paedophilia charges (unqualified pedagogue) A young man worked, for two separate periods, as an unqualified pedagogue in a kindergarten. Towards the end of the employment he was accused of sexually abusing some of the children and the matter was reported to the police. He was charged with sexually offending several children in the kindergarten as well as a child in another institution. In the course of events he was exposed to a mob rule attitude and received several anonymous threats. The local City Court found him guilty of some of the charges and sentenced him to one year in prison. The unqualified pedagogue was exposed to accusations of sexually offending children and was later charged and sentenced by the local City court.

But there was no significant difference between triple 50% stenosis and single 75% stenosis. All procedures were performed in accordance with the Dericularclaration of Helsinki of the World Medical Association. By using these values and functions, this complicated strain rate profile can be read and applied to clinical use. The systems we used were consisted of : Vivid 7 Dimension digital ultrasound system, Version 7. Table-1 In animal experiment, segmental systolic function Z rose and diastolic function Peak E and Peak E/E time fell in single 50% coronary artery stenosis. Both of systolic and diastolic segmental functions are deteriorated from a single 50% coronary artery stenosis significantrly. They are deteriorating significantly as the number of lesions of 50% stenosis increases. But no significant difference is observed between lesions of triple 50% stenosis and single 75% stenosis. Discussion Reduction of coronary artery blood flow starts from 50% stenosis, thogh flow reserve starts reducing (2) from 75% stenosis. The results also remind us the invasive coronary artery intervention should be done to regain normal left ventricular segmental wall function quickly and positively, but not only to relieve chest pain.

Endothelin-1 levels are increased in patients with heart disease,particularly in acute myocardial infarction or congestive heart diseases,as well as in renal dysfunction. During heart failure,endothelin-1 levels have been demonstrated to increase in parallel with the functional capacity and severity of the disease. The relationship between endothelin-1 and left ventricular systolic function was evaluated. Patients and methods This prospective observational study involved patients with chronic congestive heart failure who were admitted to the Department of Internal Medicine of,Kochi General Rehabilitation Hospital. Forty patients (17 men and 23 women,aged 6498 years)with chronic congestive heart failure were evaluated. Exclusion criteria included acute myocardial infarction,unstable angina,and renal dysfunction ( serum creatinine> 1. Relationships between the variables were evaluated by Spearmanss correlation analysis and p values<0. However,endothelin-1 levels did not correlated with left ventricular end-diastolic volume, left ventricular end-systolic volume, or left ventricular ejection fraction (Fig. This is probably why endothelin-1 levels were not correlated with left ventricular ejection fraction(Fig. In cases of heart failure with preserved ejection fraction,endothelin-1 levels were elevated. Therefore it appears that endothelin-1 levels did not correlated with left ventricular ejection fraction because approximately half of the patients in this study were of heart failure with preserved ejection fraction. It is suggested that endothelin-1,in particular plays an important role in chronic congestive heart failure with preserved ejection fraction(2). Trends in prevalence and outcome of heart failure with preserved ejection fraction. Almazov Cardiac remodeling has clinical significance in coronary heart disease patients. Resent years some studies have revealed new mechanisms of left ventricular hypertrophy and systolic dysfunction. M-mode and two-dimensional echocardiogram was performed (Vivid7, General Electric).

Riyadh, Saudi Arabia 2 Prof of Anesthesia & Pain Management Unit, Dept of Pharmacology, Univ. Riyadh, Saudi Arabia Summary In patients with ischemic heart disease, impairment of left ventricular diastolic function commonly 1 occurs before systolic dysfunction [ ]. Diastolic dysfunction presents as a range of severity from mild, with little clinical effect, to severe. This form of cardiac failure remains under recognized in the postoperative 2 setting, as the clinical features are similar to systolic cardiac failure allowing for a misdiagnosis [ ]. It is therefore important to make the distinction between these two forms of heart failure as their management is different. The diagnostic criteria for diastolic heart 4 failure in the postoperative heart have been described [ ]. Diastolic heart failure can complicate the postoperative course therefore, its recognition is crucial for appropriate care. The usual method of assessing cardiac failure by the relationship between ventricular filling pressure and stroke volume does not distinguish between systolic and diastolic heart failure. According to the European criteria, a normal cardiac index in 9 the face of pulmonary edema suggests diastolic heart failure [ ]. The chief points to help in the diagnosis of diastolic heart failure in the postoperative heart are: 1. Every effort should be made to identify patients who had or are at risk to develop diastolic heart failure. Chronically uncontrolled hypertension is the most common predisposing factor for diastolic heart failure should be sought 14 and aggressively treated prior to surgery[ ].
