[The families of diabetic children: a 2-year follow-up].

A great amount of clinical and experimental evidence has been accumulated on the role of immunological early events in the development of type 1 diabetes mellitus. In order to try to make a precocious diagnosis of type 1 diabetes mellitus, the Authors have studied all the components of the family in a group of diabetic children. This study is a part of a collaborative International Study called IFS (International Family Study). The Authors describe the scheme of this project in detail. During this study the Authors made a very early diagnosis of diabetes in a child, brother of another diabetic boy. The importance of this approach to the diabetic disease is discussed.

Plasma renin activity (PRA) in type I diabetes mellitus: PRA and metabolic control in diabetes.

Plasma renin activity (PRA) and aldosterone were evaluated in 39 diabetic children and adolescents and in 39 healthy subjects. The mean values of PRA in the diabetics were higher than in controls not only basal (means +/- SD: 2.7 +/- 1.1 vs. 1.3 +/- 0.6 ng/ml/h) but also after physical exercise (5.2 +/- 3.84 vs. 2.8 +/- 0.7 ng/ml/h). Aldosterone was similar in diabetics and controls (basal: 18.1 +/- 6.6 vs. 16.9 +/- 5.1 pmol/l; after physical exercise: 5.3 +/- 14.1 vs. 39.9 +/- 7.1 pmol/l). There was a significant correlation between HbA1c and PRA after exercise (p less than 0.01). The diabetic children were subdivided into 3 groups according to their stable HbA1c values (group A: less than 8.5%; group B: 8.5-10.9%; group C: greater than 11.0%). A group of diabetics (group C) were re-evaluated after a long period of a good metabolic control. The values of PRA were decreased and similar to the controls (PRA basal values: 1.7 +/- 1.9 ng/ml/h; after exercise: 3.2 +/- 2.9 ng/ml/h). Our study suggests that PRA abnormalities present in diabetic patients can be reversible if a good metabolic control is achieved.

[Epidemiology of measles and its complications in Italy. Personal experience with a hospital case load].

The authors relate and comment on the results of admission for measles in the Hospitals of Chieti and Pescara, in the period between 1974 and 1983. The authors have studied the number of admissions and their duration; moreover, they have evaluated the relationship with the pediatric population of the considered area. They point out the importance of the complications of measles to determine the admission's length to Hospital.

[Osteoarticular tuberculosis without pulmonary involvement. Description of 2 pediatric cases].

Tuberculosis of bone and joint is becoming uncommon in childhood, overall in absence of clinical and radiologic pulmonary findings. The Authors describe two cases: the first one had typical radiologic picture of the hand localization; the second one had tibial localization. Both the children had none clinical and radiographic findings of pulmonary tuberculosis. Chemiotherapical treatment and bed rest led to complete recovery, without anatomic and functional sequelae.

[Electrolytic changes in febrile convulsions].

The authors valued some metabolic parameters (sodium, potassium, calcium, blood levels of glucose, proteins, nitrogen, creatinine) in 159 children with febrile convulsions and compared the results with those of a group of children with fever (50 subjects) and of a group of health, fever free children (50 subjects). In the patients with febrile convulsions serum levels of sodium, calcium and osmolarity resulted significantly lower than those obtained in both control groups. The electrolytic modification (overall hyponatremia, probably due to a SIADH) may have a role in short-term relapses of febrile convulsions. Hyponatremia is present also in some children with high fever, without seizures; it may be that hyponatremia, in predisposed subjects, lower the threshold of neuromuscular excitability.

Education, knowledge and metabolic control in children with type 1 diabetes.

We studied thirty diabetic patients and we evaluated their knowledge of main topics of diabetes mellitus. The level of the knowledge was evaluated by multiple choice questionnaires. On the basis of score obtained the patients were divided into two groups: Group A, with high knowledge level, Group B, with low knowledge level. All the patients were followed-up for a 12 months period after a careful education. At the end of follow-up, we compared the Group A patients with another group of 14 diabetic children, who have followed an educational programme from the diagnosis of the disease (Group C). We assessed the knowledge score and the principal metabolic parameters in the three groups of patients; during the follow-up, we found a significant increase of these parameters in Group A and B patients, more evident in Group A patients. At the end of follow-up, the Group C patients showed a higher knowledge score and metabolic parameters than the Group A children. This study shows that education of disease is important for the increase of metabolic parameters and its usefulness is higher if is carried out from the onset of the disease.

[Family history and risk of insulin-dependent diabetes mellitus: a population-based case-control study].

Insulin-dependent diabetes mellitus (IDDM) is a worldwide occurrence disease of childhood with genetic, environmental and familial risk factors. Our study aims to evaluate family history as a determinant of IDDM. In a population-based case-control study informations on all incident IDDM cases, age 0-14, diagnosed between January 1st 1990 and December 31st 1996 were taken from the IDDM population-based register of the Abruzzo Region. The control group was taken from the lists of children attending family paediatricians. The family history data collection for IDDM and non insulin-dependent diabetes (NIDDM) were obtained by a questionnaire, administered to parents. Risk of IDDM associated with familiarity in first and second degree relatives was estimated using conditional regression analysis. Our results show that the risk of developing IDDM is increased by positive family history (OR = 3.99; 95% c.i. 1.56-10.23). The risk of IDDM for children whose fathers or brothers are affected by IDDM is respectively 11 and 20 times higher than for children with no family history. Family history for NIDDM does not influence the risk.
