Abstract
Background: New chemotherapeutics are urgently required to treat Candida infections caused by drug-resistant strains. Methods: The effects of 16 1,10-phenanthroline (phen)/1,10-phenanthroline-5,6-dione/dicarboxylate complexed with Mn(II), Cu(II) and Ag(I) were evaluated against ten different Candida species. Results: Proliferation of Candida albicans, Candida dubliniensis, Candida famata, Candida glabrata, Candida guilliermondii, Candida kefyr, Candida krusei, Candida lusitaniae, Candida parapsilosis and Candida tropicalis was inhibited by three of six Cu(II) (MICs 1.52-21.55 μM), three of three Ag(I) (MICs 0.11-12.74 μM) and seven of seven Mn(II) (MICs 0.40-38.06 μM) complexes. Among these [Mn2(oda)(phen)4(H2O)2][Mn2(oda)(phen)4(oda)2].4H2O, where oda = octanedioic acid, exhibited effective growth inhibition (MICs 0.4-3.25 μM), favorable activity indexes, low toxicity against Vero cells and good/excellent selectivity indexes (46.88-375). Conclusion: [Mn2(oda)(phen)4(H2O)2][Mn2(oda)(phen)4(oda)2].4H2O represents a promising chemotherapeutic option for emerging, medically relevant and drug-resistant Candida species.

Abstract
Background: Scedosporium/Lomentospora species are human pathogens that are resistant to almost all antifungals currently available in clinical practice. Methods: The effects of 16 1,10-phenanthroline (phen)/1,10-phenanthroline-5,6-dione/dicarboxylate chelates containing Cu(II), Mn(II) and Ag(I) against Scedosporium apiospermum, Scedosporium minutisporum, Scedosporium aurantiacum and Lomentospora prolificans were evaluated. Results: To different degrees, all of the test chelates inhibited the viability of planktonic conidial cells, displaying MICs ranging from 0.029 to 72.08 μM. Generally, Mn(II)-containing chelates were the least toxic to lung epithelial cells, particularly [Mn2(oda)(phen)4(H2O)2][Mn2(oda)(phen)4(oda)2].4H2O (MICs: 1.62-3.25 μM: selectivity indexes >64). Moreover, this manganese-based chelate reduced the biofilm biomass formation and diminished the mature biofilm viability. Conclusion: [Mn2(oda)(phen)4(H2O)2][Mn2(oda)(phen)4(oda)2].4H2O opens a new chemotherapeutic avenue for the deactivation of these emergent, multidrug-resistant filamentous fungi.

Abstract
Foodborne diseases are common illnesses caused by the consumption of food contaminated with microorganisms, such as viruses, fungi, bacteria, and protozoa. Every year, 600 million people become ill and 420,000 people die as a result of consuming contaminated food. Therefore, food safety is an important issue. In this study, samples of homemade spiced mayonnaise and self-serve acai sold in the city of Araguaína, Tocantins, Brazil were analyzed for microbiological contaminants. Acai was collected from 10 stores, one sample from each store, and tested for mold, yeast, and coliforms, as well as coliform identification and total and thermotolerant coliform counts. Mayonnaise was collected from 20 snack bars, one sample from each. These samples were inoculated on MacConkey and Salmonella Shigella agar plates, and the plates were analyzed for growth. Salmonella spp. were detected in some Mayonnaise samples, and coliforms were detected in all acai samples; 60% of samples had thermotolerant coliforms, and only 40% were within the limits established by ANVISA. The collected samples of mayonnaise and acai were contaminated with molds and yeasts above the established limit of 103 CFU/g. Thus, the analyzed mayonnaise and acai samples were contaminated and unfit for consumption, demonstrating the importance of hygienic-sanitary measures in food handling.

Abstract
Cryptosporidium spp. has been recognized as an important pathogen. As bivalve mollusks are noted as potential sources of several pathogens due to their consumption as foodstuffs, the aim of this study was to investigate the occurrence of Cryptosporidium spp. oocysts in Perna perna mussels and in seawater samples from a mussel farm in Southeastern Brazil, where mussels are grown directly in the sea, attached to ropes. Oocysts were observed by microscopy and confirmed by an enzyme-linked immunosorbent assay. Oocysts were present in mussel gills and GI tracts, as well as in the seawater. Of the 100 females, 10% and 11% showed contaminated GI tracts and gills, respectively, while this rate was lower in males, at 5% and 8.9%. Oocysts were present in higher amounts in the GI tract compared to gills and water. Contamination of the study area is apparent, leading to public health risks. More in-depth studies are needed, including molecular investigations, to identify Cryptosporidium species in mussels, as well as the implementation of monitoring actions in animals destined for human consumption.

Abstract
OBJECTIVES To evaluate the clinical and radiological presentations of papillary breast lesions and to evaluate the performance of core needle breast biopsy in papillary lesions. MATERIAL AND METHODS We retrospectively studied 55 papillary breast lesions in 46 patients aged 28 to 87 years diagnosed using core needle biopsy in the period 1994-2005. We reviewed the clinical and radiological presentations of the lesions, the findings at histological study after percutaneous biopsy, and the correlation of these findings with those of the surgical biopsy (44 cases) and/or radiological follow-up (42 cases). RESULTS The most common mammographic presentation was circumscribed or ill-defined, single or multiple nodules. Ill-defined lesions were significantly associated with malignancy (p < 0.05). The results of the percutaneous biopsy were: benign papillary lesion (n = 32), papillary lesion with atypia (n = 9), and malignant papillary lesion (n = 14). The diagnostic accuracy of core needle biopsy calculated from the 44 cases with surgical confirmation was: sensitivity 63%, specificity 100%, predictive positive value 100%, predictive negative value 73%, and rate of underestimation 25%. During follow-up, increased lesion size or the appearance of new lesions was seen in four patients. CONCLUSIONS The diagnosis can be suspected in cases of postmenopausal patients with multiple circumscribed or ill-defined, solid or mixed lesions at ultrasound study. Although the finding of an invasive malignant papillary lesion after percutaneous biopsy enables treatment to be planned, in the remaining situations (benign papillary lesion, with atypia, or carcinoma in situ) underestimation is common and the lesion should be surgically excised. Vacuum-assisted biopsy systems might improve these results.

Abstract
OBJECTIVES To use two rapid human immunodeficiency virus (HIV) tests at labor, measure test acceptance and performance, and measure HIV prevalence in these women. METHODS Between February and October 2000, two rapid tests (Determine; Abbott, Chicago, IL, U.S.A. and Double Check; Orgenics, Yavne, Israel) were used in three public maternities in Rio de Janeiro, Brazil. Enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) analysis confirmed positive and discordant results. RESULTS Of the 858 patients who were enrolled, the mean gestational age was 36 weeks (median = 39, mode = 40) and 17 (2%) refused testing. Of the 841 patients tested, 13 were positive by both tests, which represents a 1.5% prevalence (95% confidence interval: 0.7%-2.3%); all were confirmed by ELISA and WB analysis. Seven samples gave discordant results by the rapid tests; of these, six were ELISA-negative/WB-negative and one was ELISA-negative/WB-indeterminate. The positive predictive value for samples that were positive by both rapid tests simultaneously was 100%. CONCLUSIONS Two rapid HIV tests used at labor were well accepted (98%). When the combined results of the two rapid tests (but not a single rapid test) were analyzed, this strategy was as efficient as the standard ELISA and WB HIV strategy for correctly classifying individuals.

Abstract
The aim of this study was to examine the evidence, and consider the differential diagnosis, for tuberculosis (TB) in juvenile individuals from early 20th century documented skeletons. There are 66 male and female juvenile individuals in the Coimbra Identified Skeletal Collection (CISC) with an age at death ranging from 7-21 years. The individuals died between 1904-1936 in different areas of Coimbra, Portugal. Eighteen of these individuals died from TB affecting different parts of the body. Thirteen (72.2%) showed skeletal lesions that may be related to this infection. Of the 48 individuals with a non-tuberculous cause of death, only 2 (4.2%) had skeletal changes that could be attributed to TB. The distribution of skeletal manifestations caused by the types of TB under study, based on macroscopic and radiological findings, is described and discussed. In addition, the medical records from 6 tuberculous individuals who died in Coimbra University Hospital (CUH) were analysed, and the information, including their diet and access to treatment, is presented. This work, based on data arising before antibiotics became available for treatment, can contribute to the future diagnosis of TB in non-documented skeletal material, and will facilitate a more reliable diagnosis of TB in juvenile individuals.

Abstract
INTRODUCTION AND AIMS Homocysteinemia is an independent risk factor of coronary artery disease and of myocardial infarction. In the present study we intend to relate fasting homocystein levels to prognosis after a myocardial infarction. METHODS From 1990 to 1992, we studied fasting homocysteinemia levels on a group of 112 patients aged under 56 years that had suffered a myocardial infarction between 3 and 12 months before. We obtained, the patients names, addresses, phone numbers and physicians' name. Seven years later (on average) we collected data regarding the patients evolution, consulting medical records, their physicians or by personal contact. We evaluated complications, namely mortality, vascular morbidity, such as unstable angina, re-infarction, stroke, and the need for invasive procedures (catheterism, PTCA, CABG). According to previous studies of the group, we used a cut-point of 10.10 mumol/L to define patients with normal or pathological levels of homocysteinemia. We excluded all patients that took vitamin B supplements, co-factors of HC metabolism, during this follow-up. RESULTS We were able to obtain data on 110 patients. Patients with normal HC levels (n = 62) presented less global complications (26 versus 72%, p < 0.0001), non significant tendency to have lower mortality (1.6 versus 6%), had lower morbidity (14 versus 36%, p < 0.01) and lower invasive procedure need (18 versus 48%, p < 0.001). In the group with pathological homocystein levels (n = 48), those with higher homocystein levels presented a higher degree of complications. CONCLUSIONS In this population with myocardial infarction under 56 years of age, a high homocysteinemia level is an important prognostic factor. This study suggests that we can improve the prognosis and decrease the complications after myocardial infarction by lowering elevated homocystein levels.

Abstract
Apoptosis is a well-known specific process of cell death that normally occurs in physiological situations such as tissue or organ development and involution. During tumor growth there is a balance between proliferation and cell death which involves apoptotic mechanisms. In the present study genomic DNAs from 120 breast tumor biopsies were analyzed by agarose gel electrophoresis and none of them presented the fragmentation pattern characteristic of the apoptosis process. However, 33% of the 105 breast cancer patients clearly showed the apoptotic pattern when DNA from blood cells was analyzed. None of the DNAs from healthy volunteer blood cells showed any trace of apoptosis. Since the breast cancer patients were not receiving chemo- or hormone therapy, the possible relationship between blood cortisol levels and the apoptotic pattern found in patient blood cells was investigated. Using a chemoluminescence immunodetection assay, similar cortisol levels were observed in breast cancer patient sera presenting or not apoptotic blood cells and in healthy volunteer sera. Analysis of the clinical data obtained from 60 of these patients showed that patients bearing tumors of smaller size (under 20 mm) were more susceptible to the apoptotic effect in blood cells. According to the Elston grade, it was observed that 7 of 12 patients with grade III tumors (58%) presented apoptotic peripheral blood cells, in contrast to 10 of 48 patients with grade I and grade II tumors. These observations may reflect the immunosuppression characteristic of some breast cancer patients, which may contribute to tumor growth. Therefore, further studies are necessary to elucidate the factor(s) involved in such massive blood cell death.

Abstract
INTRODUCTION Previous cross-sectional studies have shown a high prevalence of chronic disease and disability among the elderly. Given Brazil's rapid aging process and the obvious consequences of the growing number of old people with chronic diseases and associated disabilities for the provision of health services, a need was felt for a study that would overcome the limitations of cross-sectional data and shed some light on the main factors determining whether a person will live longer and free of disabling diseases, the so-called successful aging. The methodology of the first follow-up study of elderly residents in Brazil is presented. METHOD The profile of the initial cohort is compared with previous cross-sectional data and an in-depth analysis of nonresponse is carried out in order to assess the validity of future longitudinal analysis. The EPIDOSO ('Epidemiologia do Idoso') Study conducted a two-year follow-up of 1,667 elderly people (65+), living in S. Paulo. The study consisted of two waves, each consisting of household, clinical, and biochemical surveys. RESULTS AND CONCLUSIONS In general, the initial cohort showed a similar profile to previous cross-sectional samples in S. Paulo. There was a majority of women, mostly widows, living in multigenerational households, and a high prevalence of chronic illnesses, psychiatric disturbances, and physical disabilities. Despite all the difficulties inherent in follow-up studies, there was a fairly low rate of nonresponse to the household survey after two years, which did not actually affect the representation of the cohort at the final household assessment, making unbiased longitudinal analysis possible. Concerning the clinical and blood sampling surveys, the respondents tended to be younger and less disabled than the nonrespondents, limiting the use of the clinical and laboratory data to longitudinal analysis aimed at a healthier cohort. It is worth mentioning that gender, education, family support, and socioeconomic status were not important determinants of nonresponse, as is often the case.

Abstract
The authors present the case of a 52-year-old male patient with severe coronary artery disease, submitted to percutaneous transluminal coronary angioplasty on a type C right coronary artery lesion. The use of a platelet glycoprotein receptor IIb-IIIa inhibitor, Abciximab, led to severe thrombocytopenia, treated only with platelet concentrate transfusions and with complete recovery. We also review the principal characteristics of the drug, its main indications and side effects. Severe thrombocytopenia has rarely been described in the literature.

Abstract
Preventive measures are the most powerful measures to treat manifestations of ischemic cardiopathy. Secondary prevention of myocardial infarction involves the following intervention areas: a) Limitation of adverse physiological and emotional consequences of the acute illness; b) Identification of the patients particularly exposed to the risk of new episodes of ischemic cardiopathy or to their consequences, namely reinfarction and sudden death; c) Institution of therapeutic attitudes, surgical or medical, that can prolong life and can oppose functional deterioration and prevent symptoms; d) Institution of measures that can oppose the progression of the initial disease that is, in almost all cases, atherosclerosis. Measures that can oppose the progression of cardiac disease and its consequences after an episode of myocardial infarction, and measures that can oppose the evolution of atherosclerosis are described in this article. The measures that can influence the risk factors after an episode of myocardial infarction are briefly commented: characteristics related to life style and physical exercise; smoking habits; plasmatic lipid levels; high blood pressure; and therapeutic substitution with estrogens after menopause. Pharmacological interventions in secondary prevention of myocardial infarction are described, namely with the following groups of substances: beta-adrenergic blocking agents; platelet active agents; anticoagulants; and angiotensin-converting enzyme inhibitors.

Abstract
OBJECTIVES Analysis of the characteristics of acute myocardial infarction in female patients admitted to a coronary care unit during a 10 year period. DESIGN Retrospective analysis of computerized data collected during a 10-year period in every patient with acute myocardial infarction admitted between 1986 and 1995. SETTING A coronary care unit of a central hospital. PATIENTS AND METHODS Data on 2439 patients were analyzed in what concerns gender, age and hospital mortality. In the restricted group of 655 patients admitted between 1993 and 1995 the prevalence of the following risk factors was assessed: arterial hypertension, dyslipidemia, smoking and diabetes mellitus. RESULTS During a 10-year period, 1918 male (M) and 521 female (F) patients were admitted, originating a 3.5 to 1 M:F ratio. The M:F relation decreased from decade to decade from 11:1 in patients under 50 years old to 1.8:1 in patients over 70 years old. Hospital mortality was 25.9% in female patients and 12.0% in male patients (p < 0.001). Mortality was similar in males and females until 60 years of age; significant differences were found only in the seventh decade of life (25% in females vs. 12% in males, p < 0.001) and in patients over 70 years old (36% in females vs. 24% in males, p < 0.005). Hypertension was significantly move prevalent in females (66% in females vs 46% in males, p < 0.001) as well as diabetes mellitus (31% in females vs. 20% in males). Similarly, a previous history of dyslipidemia was more frequently found in females than in males, but the difference was not significant (24% vs. 19%, respectively). On the contrary, smoking was significantly less frequent in female patients (11% in female patients vs. 44% in male patients, p < 0.001). CONCLUSIONS The probability of the occurrence of acute myocardial infarction is very low in premenopausal women. The M:F ratio decreases with aging. The risk of death progressively increases with age, and it is significantly higher in females in relation to males after the age of 60 years. Women, besides being older, have a higher prevalence of coronary artery disease risk factors, namely hypertension, diabetes mellitus and dyslipidemia.

Abstract
The aim of this study was to evaluate the efficacy of an iron prophylactic supplementation program, in three health centers of Santo André, in São Paulo state. The prevalence of anemia was identified in a control group consisting of 201 children of 1 year old. The intervention group consisted of 308 children younger than 3 months, but 55% of them gave up during the survey. The mothers were instructed to give them daily prophylactic doses of iron sulfate (6 mg of iron/day) when they were 4 or 6 months old, according to the kind of breast-feeding. The mothers were also instructed about feeding and anemia and its risk to children's health. When the children were 12 months old, the diagnosis of anemia was made through dosage of hemoglobin concentration and the results were compared with those of the control group. It was verified that the 2 groups presented similar prevalences. It is important to realize that children with low frequency of visits to the health centers had prevalence of anemia significantly higher than those with high frequency. Some factors that possibly contributed to the result of the intervention are discussed.

Abstract
We describe the use of probit analysis to estimate breastfeeding indicators from current status epidemiological data. A health centre-based sample of 2411 children aged 0-1 year was investigated in Santo Andre, a large town in the Metropolitan Area of Sao Paulo, southeastern Brazil. Mothers were interviewed during routine pediatric consultations and asked about their current infant feeding practices. Probit regressions were calculated by a public-domain microcomputer programme written by one of us. The median duration of total (i.e. exclusive plus partial) breastfeeding in this children's sample, estimated as 108.8 days (95 per cent confidence interval: 95.5-123.2 days), is close to that recently reported in the city of Sao Paulo and nearby towns. However, the median duration of exclusive breastfeeding (28.9 days, 95 per cent CI: 17.9-38.3 days) is rather short when compared to recent estimates from this same region. Despite the nationwide efforts for promotion of exclusive breastfeeding, only 14 per cent (95 per cent CI: 12.3-17 per cent) of the infants were still being exclusively breastfed by 120 days of age. Therefore, a key feature of breastfeeding practices in this population sample, namely, the early introduction of supplementary foods, was identified by using simplified methods of data collection and analysis. This communication suggests that probit analysis of current status data may be further explored as a method for rapid epidemiologic assessment of breastfeeding practices.

Abstract
Ingestion of organophosphate (OP) compounds usually results in severe poisoning. We undertook a retrospective study of 52 consecutive patients admitted with severe OP poisoning to determine the value of serum cholinesterase (SChE) in monitoring clinical course. Considering survivors and non-survivors, we evaluate clinical and laboratory baseline characteristics, severity scores (APACHE II, SAPS II), atropine rate (mg/h), SChE evolution at 24, 72 and 120 h and final SChE (SChE at the day of discharge or death). Mortality in the ICU was 28.9% (n = 15). In both groups SChE showed a trend to increase. In survivors, SChE recovery was statistically significant for SChE 24h-SChE 72 h, SChE 24 h-SChE 120 h and SChE initial-SChE 120 h (p = 0.008, p = 0.00003, p = 0.0002 respectively). In this group a simultaneous decrease in atropine requirements was registered. In non-survivors, the rate of atropine remained unchanged up to 120 h. Three groups could be defined in non-survivors according to their final SChE and day of death. Non-survivors-1 (death in the first 24h; 2 patients) and non-survivors-2 (death after the first 24 h; 5 patients) had a final SChE below 10% of normal SChE activity and statistically different from survivors' final SChE. Non-survivors-3 (8 patients) had a final SChE similar to the survivors and death was due to sepsis and multiple organ failure (MOF). We conclude that SChE is useful in OP poisoning diagnosis and also in monitoring clinical course. SChE recovery above 10% of normal seems to correlate with good prognosis. Sepsis and MOF were important determinants of mortality.

Abstract
In the present study, the authors evaluate the haemodynamic effects of continuous captopril therapy during one-year after a first anterior myocardial infarction (MI). Haemodynamic measurements are made during the first 48 hours after de MI and repeated one year later. Patients are divided in two groups: The first group had therapy with acetylsalicylic acid (ASA) and isosorbide dinitrate (ISDNI) and the second group had therapy with ASA, ISDNI and captopril. From their results the authors conclude that captopril helps peripheral resistances elevations, and that this is one of the mechanisms by which it can have a favourable effect after an anterior MI.

Abstract
The authors describe the diagnostic and therapeutic management of 55 patients with the diagnosis of unstable angina admitted at a medical intensive care unit. According to Braunwald classification, 52 patients had primary angina and the remaining three had post-infarction angina. Risk stratification was based on non invasive procedures such as 2D echocardiogram and exercise test after clinical stabilization. Coronary angiography was performed in all patients. Most of the patients needed revascularization: 62% by percutaneous transluminal coronary angioplasty (PTCA) and 13% were submitted to coronary artery by-pass graft (CABG). None of the patients died during hospitalization.

Abstract
There was been some controversy about non-Q wave myocardial infarction, its evolution and prognosis. The most recent studies showed that, in spite of the low immediate mortality in non-Q wave myocardial infarction, the long-term risk of ischaemia, reinfarction or sudden death is equal or even greater than in the Q-Wave myocardial infarction. In order to define an adequate ischaemic risk stratification strategy in the post non-Q wave myocardial infarction without complications, the authors studied 21 patients who were submitted to treadmill exercise test and coronary angiography within 30 days after the acute event. Of the 17 patients with positive stress testing, 14 showed significant relationship between ischaemic area detected in the stress testing and the anatomic localization and severity of the lesions in the coronary angiography (chi 2 = 14,875; p < 0.006). Revascularization therapy (PTCA or bypass surgery) was very high in this group of patients (47.6%). From the date obtained the authors conclude that it is not necessary to use invasive studies in every patient that has suffered from non-Q wave myocardial infarction without complications, since the stress testing showed high sensitivity (94.4%), specificity (75%) and high predictive value (100%) in the ischaemic risk stratification.

Abstract
OBJECTIVE Brief description of a clinical information system and its application to 2334 cases of acute myocardial infarction. DESIGN To evaluate the influence on intra-hospital prognosis of 22 clinical characteristics observed in patients on the acute phase of myocardial infarction admitted to a coronary care unit. SETTING Coronary care unit. PATIENTS 2334 cases of myocardial infarction admitted sequentially to a coronary care unit. MATERIAL AND METHODS A locally developed computerized information system was used. Software was organized in a modular way in order to turn available simplicity, flexibility and expandibility which are requisites of an automatic information system operating in a coronary unit. Following characteristics were evaluated: age and sex; previous myocardial infarction, angina, hypertension, diabetes, tabagism and hyperlipidemia; electrocardiographic localization of the infarction; ventricular dysfunction as evaluated by Killip classes; supraventricular and ventricular dysrhythmias; auriculo ventricular and intraventricular blocks; epistenocardic pericarditis; intra-hospital extension of the infarction; transient episode of hypertension and post-infarction angina. Statistical association between these characteristics and intra-hospital mortality was evaluated. Statistical significance was considered with a p less than 0.05. RESULTS Statistical significant differences were found between surviving and non-surviving patients in the following characteristics: age and sex; previous history of myocardial infarction, angina and diabetes; Killip classes distribution; electrocardiographic localization of the infarction; intra-hospital extension of the infarction; auriculoventricular block, left and right bundle branch block; supraventricular and ventricular dysrhythmias. Patients with a previous history of tabagism and hyperlipidemia had a lesser mortality and were younger than the patients without these characteristics. Patients with transient episodes of hypertension and epistenocardic pericarditis had a lesser hospital mortality. CONCLUSIONS Local development of a computerized information system turned available clinical information of 2334 patients sequentially admitted to a coronary care unit. A worse intra-hospital prognosis was present in the following groups of patients: older patients and females; patients with a previous history of infarction, angina and diabetes; anterior myocardial infarction, left ventricular dysfunction as evaluated by Killip classes, ventricular and supraventricular dysrhythmias, auriculoventricular and intraventricular blocks, transient episodes of hypertension and extension of the infarction. Patients with a previous history of tabagism and hyperlipidemia had a lesser mortality; however, there patients were younger than other. Patients with transient episodes of hypertension on first hours of infarction and those who had epistenocardic pericarditis had a lesser mortality.

MATERIAL AND METHODS Making use of a computerized information system the following characteristics f the patients were prospectively studied: age, sex, previous history of myocardial infarction, angor, diabetes, hypertension and tabacism, presence of left ventricular dysfunction electrocardiographic localization of the infarction, presence of angor in the acute phase of the infarction, epistenocardic pericarditis, hypertensive reaction, hypotension, sinus tachycardia, sinus bradycardia, supraventricular disrhythmias, ventricular disrhythmias, A-V block, complete right bundle branch block, complete left bundle block and peak of CPK values. Univariate analysis was made between each one of these characteristics and hospitalar and one year mortalities. RESULTS Statistically significant differences were obtained in the hospitalar mortality in the following characteristics: age (p less than 0.001), sex (p less than 0.03), previous history of diabetes (p less than 0.05) and tabagism (p less than 0.005), left ventricular disfunction (p less than 0.0005), hypotension (p less than 0.005), sinus tachycardia (p less than 0.0005), sinus bradycardia (p less than 0.024), A. V. block (p less than 0.004), and peak of CPK (p less than 0.05). Statistically significant differences were found in one year mortality in the following characteristics: age (p less than 0.001), left ventricular disfunction (p less than 0.02), sinus tachycardia (p = 0.0116) and peak of CPK (p less than 0.05). CONCLUSION Influence in the hospitalar mortality was demonstrated by the following characteristics of the patients with myocardial infarction: age, sex, previous history of diabetes and tabagism, left ventricular disfunction, infarct size expressed by the peak values of CPK, sinus tachycardia, sinus bradycardia, hypotensive reaction in the acute phase of the myocardial infarction and A-V block. Mortality in the late phase infarction was influenced by age, left ventricular dysfunction, sinus tachycardia and peak values of CPK.

Abstract
Surgical mortality rates were reviewed for the four-year period 1970-1973, in a series of 2,186 operations. The majority of these operations were performed in patients aged 70 or older; of these, 116 were performed in patients of the 90+ age group. Predictably, the surgical mortality in the older groups was higher than in the younger groups. However, the overall mortality for patients aged 70 or older was 4.9 per cent as compared with 8 to 21 per cent for series reported in the literature. Gastrointestinal, biliary, and chest procedures carried a much higher mortality than did the other major categories. Minor surgical operations in the elderly should be approached with caution since they may be associated with a significant mortality rate. Nevertheless, elderly patients should not be denied surgical intervention, major or minor, on the basis of age alone when the operation can make their remaining years more comfortable.
