Blood zinc, copper and magnesium in aging. A study in healthy home-living elderly.

BACKGROUND: Blood concentrations of copper, zinc and magnesium were determined in healthy elderly to assess whether aging interferes with mineral and micronutrient status. EXPERIMENTAL DESIGN: case series. SETTING: Internal Medicine and Geriatrics ambulatories in a University Hospital in Pisa, a city of Central Italy. PARTICIPANTS: 143 healthy outpatients of both sexes, who underwent a cardiological examination. INTERVENTION: no treatment and intervention were performed. MEASURES: copper (Cu), zinc (Zn) and magnesium--both intraerythrocytic (iMg) and extracellular (eMg)--were measured. RESULTS: The concentrations of Cu and eMg were found significantly higher in the elderly: Cu 117.5 +/- 17.0 micrograms/dl in the elderly vs 102.5 +/- 19.6 micrograms/dl in the younger (p < 0.001); eMg 1.8 +/- 0.2 in the elderly vs 1.7 +/- 0.2 mEq/l in the younger (p < 0.05). On the other hand, the levels of Zn and iMg did not differ in the two groups: Zn 113.3 +/- 14.9 micrograms/dl in the elderly vs 118.0 +/- 17.3 micrograms/dl in the younger, p = n.s.; iMg 4.3 +/- 0.4 mEq/l in the elderly vs 4.2 +/- 0.4 mEq/l in the younger, p = n.s. No correlation was found between age and single elements. CONCLUSIONS: These results suggest that the healthy free-living elderly have an adequate mineral intake. Nutrient supplements may by useful in the elderly with chronic diseases, comorbidities, and polypharmacy to prevent further age dysfunctions.

Takayasu's arteritis on steroid therapy. Seven years follow-up.

The authors report a 7 year follow-up of Takayasu's arteritis (TA) type III, group 1, in a young Italian woman. At diagnosis, at the age of 25, the echotomographic and angiographic studies showed narrow subclavian arteries, narrow abdominal aorta (diameter of 0.6-0.8 cm) below the renal arteries, stenotic left common carotid and renal arteries, and occluded upper mesenteric artery. With steroid therapy, (prednisone 50 mg/day per os), the erythrocyte sedimentation rate (ESR) normalized within 12 days. With a maintenance dosage of 7.5 mg/day per os, the patient achieved remission as documented by the absence of symptoms, the persistent normalization of ESR, and the improving of the diameter of the abdominal aorta (1.3-1.4 cm). On steroid therapy, the patient had a normal pregnancy and delivered a healthy baby girl. The disease has been stable for seven years. Recently, diabetes mellitus occurred and it has been treated with insulin therapy. The rising of ESR after tapering of steroid therapy (prednisone 5 mg per os on alternate days) suggests an alternative treatment with a cytotoxic agent.

Tortuosity, kinking, and coiling of the carotid artery: expression of atherosclerosis or aging?

The etiology of carotid abnormalities is both congenital than acquired. The aim of this study was to clarify the role of aging and atherosclerosis in the acquired cases, and the role of these abnormalities in hemodynamic alterations and neurologic symptoms. Over a 1-year period the authors studied all the subjects undergoing carotid examination by continuous-wave and color-coded Doppler sonography at an Angiology Unit. They evaluated neurologic symptoms; risk factors for atherosclerosis; number, sites, and kinds of carotid abnormalities; atherosclerotic lesions; stenosis; hemodynamic alterations of the carotid; and other localizations of atherosclerotic diseases. There were 469 subjects: 272 (58%) with abnormalities (group 1) and 197 (42%) without abnormalities (group 2). The total number of abnormalities was 479 (104 tortuosities, 262 kinkings, and 113 coilings). The abnormalities were more prevalent in the elderly (P<0.001) and in women (P<0.001). In group 1 they found significant prevalences of hyperlipemia (P<0.001), hypertension (P<0.01), chronic cigarette smoking (P<0.01), and ischemic heart disease (P<0.05). Carotid atherosclerotic lesions were more prevalent in group 1 than in group 2 (P<0.001); among the patients with atherosclerotic carotid lesions, those in group 1 were older than those in group 2 (P<0.001). Tortuosity seemed to be associated with fewer hemodynamic alterations. The authors conclude that atherosclerosis, hypertension, and aging may play an important role in producing carotid abnormalities. The aging seemed more important than atherosclerosis. Only a prospective study of patients with carotid abnormalities and no atherosclerotic lesion will clarify the role of hemodynamics and neurologic symptomatology.

[5-Aminosalicylic acid in the prevention of recurrences of Crohn's disease]. / 5-Aminosalicylsäure in der Rezidivprophylaxe des Morbus Crohn.

AIM OF STUDY: To evaluate the efficacy of 5-aminosalicylic acid (5-ASA) in preventing recurrences of Crohn's disease. PATIENTS AND METHODS: Between January 1988 and December 1989 a total of 60 patients (37 men, 23 women, mean age 34.8 years) were selected in whom the diagnosis of Crohn's disease had been known for at least 2 years. A further criterion for inclusion was remission for at least one year in patients who had been operated or for one month in the nonoperated ones. Furthermore, the latter must have had at least one recurrence during the last year. They were in turn assigned to be treated with 5-ASA (2.4 g daily by mouth) or not treated (control). The activity and localization of Crohn's disease were defined according to the "Crohn's disease activity index" (CDAI) and the "laboratory index" (LI), as well as by endoscopy and (or) radiology. The patients were examined every 6 months for 4 years. A recurrence was diagnosed if the CDAI was more than 150 or had increased to at least 60 points above the initial value and the LI was above 100. RESULTS: 29 recurrences were noted, 72.4% within the first 2 years. 15 recurrences (46.9%) were in the treated patients and 14 (58.3%) among the untreated controls. The Kaplan-Meier curve (statistical comparison of the probability of recurrence) showed no significant difference between the two groups (P = 0.23): the recurrence rate was the same in the two groups, among the patients with or without previous operation and for different primary localizations. There were no notable side effects. CONCLUSION: Treatment with 5-ASA was not found to influence the likelihood of recurrence. Age, duration of the disease, primary localization and previous operation were not prognostic factors.

[Malignant peritoneal mesothelioma: its relation to asbestos]. / Il mesotelioma maligno peritoneale: la relazione con l'asbesto.

Chronic exposure to asbestos can induce malignant peritoneal mesothelioma (PMM) without pulmonary or pleural involvement (PIMM). The localization to the peritoneum depends on the different susceptibility of the two mesotheliums and, perhaps, on the length of asbestos fibers which can facilitate their direct translocation.

[Falls and fractures in the elderly. Causes and consequences]. / Cadute e fratture nell'anziano. Cause e consequenze.

OBJECTIVE: To evaluate the causes of non-pathologic traumatic fractures in the elderly and their consequences on quality of life. DESIGN: A prospective trial. FOLLOW-UP: 12 months for the inpatients and 3 months for the outpatients. SETTING: Basal assessment in orthopaedic hospital; follow-up in geriatric unit. PATIENTS: Both inpatients and outpatients, 65 years and over, both sexes, both living in a nursing home and in their own home, admitted to an orthopaedic hospital because of a fall, with diagnosis of a subsequent fracture. Criteria of exclusion: patients with pathologic fracture. 121 patients were enrolled, 108 had a complete follow-up. SURVEYS: Health and functional status prior to the fracture, causes and concomitant causes of the fall, site of the fracture, complications and functional disabilities. RESULTS: The most frequent cause of fracture is an accidental fall, especially in younger elderly, other causes being acute cardiovascular and neurological diseases. Fractures occur more frequently in females. The most serious injuries affect frailer subjects, with advanced age, neurologic and multiple chronic diseases. Fracture of femur is the most frequent fracture and it has the highest risk complications, functional disabilities and death. CONCLUSIONS: Because of the high frequency of accidental falls, the authors emphasize the necessity of primary prevention, especially the removal of architectural barriers both at home and in public environment.

[Dilated cardiomyopathy and visceral anomalies in myotonic dystrophy]. / Cardiomiopatia dilatativa ed anomalie viscerali nella distrofia miotonica.

In dystrophia myotonica clinical evidence of cardiac involvement usually appears several years after the onset of neuromuscular symptoms. In more than 90% of cases there is damage to the specialized cardiac tissues and in about 7% of cases there are alterations to the myocardium. We report a case characterized by early and spread deterioration of the pump function developing into refractory congestive heart failure. The contemporary involvement of the smooth muscle of gallbladder and colon confirms the hypothesis that dystrophia myotonica is a pan-muscle disease.
