Diet and coronary arterial disease: a statistical study.

Statistical analysis comparing mortality rates from coronary arterial disease with food consumption in 21 countries belonging to the Organisation of Economic Cooperation and Development is presented. In a preliminary process correlation coefficients are calculated for coronary mortality and all food items appearing in statistics collected for food consumption as well as for some combinations of food items. The highest correlations obtain with oats, milk proteins (other than the protein content of cheese), milk fats and sugar. These items are investigated in greater detail with respect to mortality from coronary arterial disease in males and females in various age groups and for various time intervals between the dates of mortality and statistics for food consumption. Correlations tend to increase in the older age groups and with longer time intervals. The highest correlation coefficient found is 0.94 for deaths due to coronary arterial disease for males in the 65-74 age group with the combined consumption of oats and milk proteins.

[Analysis of in vivo and in vitro radioisotopic tests for studying hypothyroidism. Statistical study of parameters coming from routine investigations in normal subjects and hypothyroid patients].

This report analyses quantitative data collected during spontaneous examination in normal subjects and in hypothyroid subjects, attempting to determine what figures obtained in this way can provide in the diagnosis of this disease. 125I tests in vitro today play a very important role and suffice der detection provided radio-immunoassay is carried out, whether the latter concerns iodine hormones or the thyreotropic pituitary hormone and provided the diagnosis is not confirmed by one single examination. The 131I kinetic test helps in classification of the hypothyroidism. Naturally, only further tests will permit us to determine certain causes (thyroid scan, Querido's test, TRF test, anionic competition, immunological study, etc.). Chemical estimations of stable iodine (127I) no longer have any place in this routine assessment, except that the total iodine is essential to interpret the kinetics in vivo.

Comprehension skill levels and prevalence of maladaptive behaviors in autistic and mentally retarded children. A statistical study.

A statistical study on the comparison of the comprehension skill levels between the group with and the group without each maladaptive behavior of nine items was done for autistic and mentally retarded children. Results indicated that the group of the autistic children with hyperactivity or withdrawal had slightly, not significantly, lower comprehension skill levels than the group of those without each of these maladaptive behaviors. On the other hand, the correlation between the prevalence of hyperactivity or withdrawal and lower comprehension skill levels was seen more clearly, with statistically significant differences, rather among the mentally retarded children.

Human DNA TATA boxes and transcription initiation sites. A statistical study.

A statistical study of "TATA", or Hogness, boxes and transcription initiation sites in human DNA protein-coding genes is presented. The range over which the two signal sequences extend is assessed, and their information content is evaluated. The results are compared with those obtained from "general eukaryotic" samples (including sequences from various eukaryotic species and viruses). Statistically significant differences are found for both signals, and are especially noticeable for transcription initiation sites. The possibility that the latter may contain sufficient information to resolve the remaining ambiguity in the position of the transcription start point once a TATA box has been located is explored.

[Pediatric orthognathic surgery (Statistical study)].

A statistical study covering five years (1983-1987) of work by the Pediatric Orthognatic Surgery Clinic at pediatric hospitals in the Centro Médico Nacional and La Raza, Instituto Nacional del Seguro Social. The bases and rationale followed by the clinic to correct dentofacial deformities in patients under 15 are described, along with services involved and surgical procedures followed in 90 pediatric patients, as compared with 165 adult patients operated within that same period, favorably confirming the hypothesis propounded in practice.

[Are orodental infectious foci responsible for bacterial pneumopathies? A statistical study].

A statistical study compared a group of 38 patients with clinically and bacteriologically confirmed bacterial pneumonia with a control group of 33 subjects. Results facted to demonstrate any significant role for buccodental infection in the genesis of bronchopulmonary infections capable of inciting stomatologists to adopt drastic measures with respect to mortified teeth within the framework of pulmonary disease.

Comparative detection of pancreatic body--tail enlargement using the supine translateral and axial pancreatic views: a prospective statistical study.

A prospective statistical study of 429 patients was undertaken to determine if the axial pancreatic view would improve detection of pancreatic body-tail enlargement. This view is produced by directing a roentgen-ray beam along the axis of the pancreatic body-tail cylinder. On this view and on the supine translateral view, a pancreatic body-tail space can be identified as a subdivision of the retrogastric space. When the pancreatic body-tail enlarges, this space selectively enlarges. The percentage change of this space is particularly impressive on the axial pancreatic view, where 10 of 12 pancreatic body-tail neoplasms were detected with only a 1.8 per cent false positive rate.

[Patterns in the recurrence and transformation of alcoholic psychoses developing against a pathologic background (clinico-statistical study)].

A clinical and statistical study has covered 689 patients with alcoholic psychoses developing against the pathologic background. The study of the correlation between the form of attacks and the type of the disease course has demonstrated some highly probable variants of relapse development and transformation of the clinical forms of alcoholic psychoses in subsequent bouts. Two variants of the course of alcoholic psychoses have been identified. In the first variant psychoses show no tendency to recur and transform while the second one is associated with their relapses and transformation. These findings make it possible to infer that the presence of pathologic background is a factor of risk and to outline on this basis the measures to prevent the development and relapse of alcoholic psychoses.

[Calcifying and non-calcifying chronic pancreatitis. A statistical study (author's transl)].

A statistical study aimed at the determination of any possible differences between calcifying and non-calcifying chronic pancreatitis. It would seem that whilst there are differences from a histopathological and biological standpoint, these differences disappear completely as far as postoperative course is concerned. Curiously enough, the long term prognosis was the same regardless of the type of pancreatitis.

[Surgery of idiopathic epiretinal macular membranes. A retrospective statistical study of the functional result. Apropos of 42 treated cases].

Presentation of 42 glial idiopathic epiretinal macular membranes, surgically removed. Complications are rare. The functional improvement is greater if the operation is carried out when the visual acuity is low but the final result is better if eyes are operated when the visual acuity is still good. The main difficulties are the impossibility to detach the membrane, and the iatrogenic tears, which often need an internal tamponade by intraocular silicone oil.

Statistical studies on the prognosis of anorexia nervosa.

Statistical studies on the prognosis of anorexia nervosa were carried out by our research group. Subjects were 224 cases from 36 university hospitals throughout Japan. A questionnaire was mailed to each of the 224 patients in cooperation with their doctors. The outcome of 143 of the 224 cases was judged by their doctors as 'good' in 47 cases, 'intermediate' in 69 cases and 'poor' in 19 cases. 8 of the patients had died. The prognosis of typical cases was much poorer than that of atypical cases.

[Clinical aspects of myocardial infarction in elderly people. Statistical study of 203 cases (author's transl)].

A statistical study was done on two groups of patients. The first group included 128 subjects of less than 65 years of age. The second group comprised 75 subjects aged 65 years or older. The purpose of the study was to identify the most relevant clinical aspects of myocardial infarction in older aged patients. The following variables were taken into consideration: sexual distribution, predisposing factors, causative factors, initial symptoms, site of infarction, physical and instrumental indications, cardiac and extracardiac complications, immobilization time, recovery time, residual aspects at patient discharge, mortality and tyme and type of death. The analysis was performed using both non parametric X2 test and correlating some variables with age independently of the subdivision of cases in groups, according to the method of multiple step-wise and simple regression. In the older age group the most significant statistical data was: the major incidence of infarcts was in women; the prevalence of predisposing factors such as hypertension and diabetes; the most frequent presentation of initial atypical symptoms; the most elevated incidence of hemodynamic complications and the highest mortality.
