The chiral title compound, C(21)H(20)N(4)O(2), crystallizes as a racemic mixture. In the crystal, mol-ecules form centrosymmetric π-overlapping dimers [inter-planar distance = 3.338 (6) Å], which are further connected along the a axis forming centrosymmetric dimers via O-H⋯N hydrogen bonds.

The distribution of iron accumulation differs between these two forms; therefore, they can be distinguished by using imaging methods in the majority of cases. Magnetic resonance (MR) imaging is the most sensitive and specific imaging modality in the diagnosis of hemochromatosis.
View Article and Find Full Text PDFA comparative study was made of the utilization of cardiovascular drugs in a long-term-care facility for the aged for 1987 and 1992 during which the age and sex distributions and incidence of usage were similar. There were statistically significant declines in the usage of diuretics and potassium supplementation, digoxin, antihypertensives, antiarrhythmics, and beta blockers and a rise in the use of calcium-channel blockers. There was a slight fall in the use of antianginal drugs.

While postural hypotension was present in almost 20% of ambulatory patients of this long-term institution, associated symptoms were infrequent. A comparison of the groups with and without a history of falls in the prior year revealed no relationship to the presence of postural hypotension and no relationship to a number of medications which have been reported to be associated with orthostatic hypotension. Blood pressure readings should be obtained at 1,3 and 5 min after assuming the erect position as significant falls in blood pressure were found at each interval.

The total number of patients in the series was 43. Comparisons were made between those patients transferred to a general acute-care hospital and those who remained at the facility.

All patients had been offered influenza vaccine before the outbreak; 181 chose to be vaccinated and 124 refused vaccination but agreed to participate in the study. Among those with serologic evidence of influenza infection, respiratory illness was significantly more common in the unvaccinated group (six of 14 vs one of 22).

A survey indicated that 59% of the residents were immunized before the outbreak. The outbreak was observed to begin in November, peak in February, and disappear in April.

Autopsies are performed much less frequently in the elderly than in younger patients. Little information exists as to causes of death in the institutionalized elderly. The clinical diagnostic error rate documented by autopsy studies ranges from 6% to 68%.

The effectiveness of immunization against influenza in elderly persons is uncertain. A retrospective cohort study in a New York City nursing home examined the occurrence of pneumonia and its related mortality over three consecutive influenza seasons (Nov 1 through April 30, 1979 to 1980, 1980 to 1981, and 1981 to 1982). Nearly one half of approximately 450 residents (mean age, 84 years) accepted immunization each year.

The prognostic significance of risk factors for ischemic and hypertensive heart disease in the aged differs in many respects from that in younger persons. In old age, most risk factors for ischemic heart disease such as an elevated level of total serum cholesterol, cigarette smoking, obesity, Type A personality and abnormal glucose tolerance have a less adverse effect on morbidity and mortality from ischemic heart disease, while an elevated level of high density lipoprotein, and moderation in the use of alcohol each have a favorable effect. A high level of low-density lipoprotein cholesterol exerts an adverse effect.

Histologic and immunologic examination as well as clinical course confirmed the diagnosis of bullous pemphigoid. the possibility of an allergic or drug-induced disease was considered because of her initial clinical and laboratory findings.

In a study to determine the nature and frequency of cardiac side effects during long-term administration of tricyclic antidepressant drugs in usual dosages in the aged, 32 geriatric patients were followed for an average of 36.6 weeks. Ten of them received amitriptyline in a daily dosage of 20-75 mg for 53 weeks (average); in 2, electrocardiographic side effects developed, viz, inversion of the T waves or evidence of acute coronary insufficiency.

In order to pursue the question of excess mortality due to chronic brain syndrome (CBS), 330 residents of a home for the aged were independently evaluated prior to admission by psychiatrists and by general physicians. Five years later, their medical records were searched to determine: 1) age on admission, 2) diagnosis of CBS on admission, 3) physical status on admission, and 4) if death had occurred, the age at death and the cause of death. Women outnumbered men by 3:1.

In an institution for the aged, 25 residents (average age, 85) in whom pacemakers had been implanted for an average of 53 months were compared to 18 residents of the same age and sex who had a slow heart rate. A semistructured interview was given to determine mental status, affective condition, perceived health, and other concerns.
View Article and Find Full Text PDFThe electrocardiogram is a valuable aid in diagnosing and treating heart disease in the elderly and in determining the prognois. In general, mortality is lower in old persons with ECG abnormalities than in younger ones, and some changes are not considered abnormal. P wave notching, slurring, and loss of amplitude are too common to be of diagnostic significance, and T wave inversions and S-T segment depressions have too many causes to be specific.
