[Prothrombotic and prethrombotic markers in obese diabetic and non-diabetic subjects].

The Authors studied the behaviour of some prothrombotic (fibrinogen, factor VII, antithrombin III and tissue plasminogen activator) and prethrombotic (beta thromboglobulin, D-dimer) markers in a group of obese subjects in relation to various physiopathological parameters. The series consist of 93 obese subjects (29 m, 64 f, mean age 55 +/- 6 yrs, BMI 33 +/- 1), of whom 62 suffering from type 2 diabetes in good metabolic control obtained by oral hypoglycemic (42 cases) or insulin (20 cases) treatment. For each subject the Authors determined the plasmatic levels of glucose, total cholesterol, triglycerides (enzymatic method, Boehringer kits), fibrinogen (coagulometric method, Organon kit), factor VII (chromogenic method, IL kit), antithrombin III (chromogenic method, IL kit), tissue plasminogen, beta thromboglobulin and D-dimer (ELISA method, Boehringer kits). The results were examined in relation to sex, age, overweight degree, waist/thigh ratio, total cholesterol, triglycerides and, for diabetics, to the therapeutical treatment. The fibrinogen plasma levels proved statistically (0.05) increased proportionally to the overweight degree (BMI over 35), cholesterol levels (over 250 mg%) and age (51-65 yrs); factor VII showed a significant increase (0.05) related to the cholesterol levels, the overweight degree and, surprisingly, to female sex; as regards antithrombin III, its sharp reduction was related with ageing and with the "gynoid type" waist/thigh ratio; tissue plasminogen activator showed a statistically significant reduction (0.05) in the group with older age (over 65 yrs); the beta thromboglobulin levels were obviously increased (0.05) in the hypercholesterolemic and hypertriglyceridemic subjects (over 250 mg%), the D-dimer values increased proportionally with age (0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

[Fibrinogen and antithrombin III in obese subjects].

The study aimed to evaluate the behaviour of two pre-thrombotic markers (hyperfibrinogenemia and hypoanti-thrombinemia) in obesity which is considered a factor of atherogenous risk. Ninety-three obese subjects were included in the study (29 M, 64 F, mean age 55 +/- 6, BMI 33 +/- 1), including 62 Type 2 diabetics. The following were assayed in each subject: glucose, total cholesterol, triglycerides (enzymatic method), fibrinogen (coagulometric method) and anti-thrombin III (chromogenic method). Results were assessed in relation to sex, age (0-50, 51-65, over 65), BMI (upto 30, 31-35, over 35), waist/hip ratio (upto 0.95, 0.96-1.02, over 1.02), cholesterolemia (upto 200, 201-250, over 250 mg%) and triglyceridemia (upto 150, 151-200, over 200 mg%). A significant increase (0.05) in fibrinogenemia was observed in the subjects aged between 51-65, with BMI above 35, with an intermediate waist/hip ratio (0.96-1.02) and with cholesterolemia over 250 mg%; reduced values of anti-thrombin III were found in subjects over 65 years old and with the lowest waist-hip ratio (upto 0.95); no significant data were obtained for the other parameters and for the correlation between fibrinogen and anti-thrombin III. The pro-thrombotic importance of hyperfibrinogenemia is underlined in obese subjects; this is proportional to age, to the degree of overweight and levels of cholesterolemia, even if equivocal results emerge with regard to the "android" variety. The reduction of anti-thrombin III is correlated to senility and, surprisingly, to the gynoid-type waist/hip ratio.(ABSTRACT TRUNCATED AT 250 WORDS)

[Poland syndrome. Clinical and structural considerations].

The Authors reported 4 cases of Poland Syndrome. In one of these was possible to perform a skin and muscle biopsy. The clinical aspects of the patients, compared with those observed in the literature are reported. The disease is a malformative syndrome, and the histological features of skin and muscle appeared not structurally affected.

[Transverse hemimelia of the lower right limb associated with sysmetrical malformations of the hands in a newborn infant].

The authors report a newborn infant affected by terminal transverse hemimelia of the right lower limb, associated with symmetric malformations of the hands, simulating the "amniotic bands syndrome". The symmetric hand anomalies and the presence of slight malformations of the left lower limb lead us to think that the etiology of this case is genetic, probably related to a new mutation.

[The newborn infant of the diabetic mother: the clinical findings in 431 subjects].

431 newborns of diabetic mothers (NDM) were studied between the years 1980 and 1990. They were divided into two groups: a first group of 227 patients born from mother with gestational diabetes mellitus; a second group of 204 patients born from mother with pregestational diabetes mellitus. The first and the second group were subdivided into two subgroups: the A, referring to the period 1980-85, and the B, referring to the period 1986-90. Subgroups B were characterized by a better metabolic control of pregnancies. Our protocol consisted of anamnestic study, clinical, metabolic, instrumental examinations and clinical follow-up for a period ranging from 1 to 10 years. The study of our data suggests that embryo-feto-neonatal mortality doesn't show significantly difference between the first and the second group and between subgroups A and B. The percentage of preterm infants was significantly more elevated in the second group, the percentage of full-term newborns was significantly higher in the first group. The incidence of cesarean sections was significantly higher in subgroups B. Mean birthweight was more elevated in the first group and the incidence of macrosomia was higher in subgroups A. The incidence of asphyxia, hypotonia, seizures, transient cardiomegaly, transient hypoglycaemia and hypocalcemia, was higher in subgroups A, without significant difference between the first and the second group. Congenital anomalies were heterogeneous and there were no significant difference between the first and the second group. Only the incidence of congenital cardiopathies was significantly more elevated in the second group. At follow-up neurologic sequelae were mainly characterized by behavioural anomalies.
