Medical care from childhood to adulthood in type 1 and type 2 diabetes.

Diabetes mellitus comprises a heterogeneous group of diseases that have in common the development of macro- and microvascular complications. It is now possible to identify subjects at high risk of Type 1 or Type 2 diabetes, especially in the patient's family members. Preventive interventions are quickly becoming available, and can help delay the onset of the disease and thereby reduce complications in these subjects. Furthermore the correct etiological diagnosis of diabetes is fundamental in providing the best treatment for the patient. Maturity-onset diabetes of the young (MODY) syndrome should be suspected in cases of a subtle onset of diabetes and autosomal dominant inheritance. Mitochondrial DNA mutations should be considered when a diabetic patient also suffers from deafness or if there is a family history of this combination in the mother side of the family. Atypical diabetes has to be identified by the physician to avoid mistakes when the patient enters the non-insulin-dependent phase. In the case of Wolfram's syndrome a gene analysis for each family member should be performed to identify heterozygote subjects. Recently, many discoveries in genetics help us better understand the pathogenesis of the diseases and diagnose the monogenic form of diabetes more easily. If all family members are followed in the same center, clues from the family history are readily available for differential diagnosis and preventive interventions can be established more effectively.

[Neonatal diabetes, heterogeneous syndrome]. / Diabete neonatale, sindrome eterogenea.

Neonatal diabetes (ND) is a rare condition of hyperglycaemia which occurs, generally, within the first month of life, requires insulin therapy and lasts more than two weeks. The pathogenesis is uncertain and the different clinical variants are heterogeneous; both a "permanent" and a "transient" form of ND exist. We report the clinical history of three neonates (A.L., A.B. and V.I.) in which a tout-court diagnosis of ND was done; the follow-up allowed us to reevaluate the initial diagnoses and suppose different ethiopathogenic mechanisms. Clinical observations, insulin requirement and biochemical data obtained during the years of follow-up allowed to distinguish three different situations: a "permanent" ND (A.L.), a "transient-recurrent" ND (A.B.), and a Maturity Onset Diabetes of the Young (MODY) (V.I.).

Effectiveness of a prevention program for diabetic ketoacidosis in children. An 8-year study in schools and private practices.

OBJECTIVE: To shorten the period of carbohydrate intolerance preceding the diagnosis of IDDM in children. RESEARCH DESIGN AND METHODS: The incidence of diabetic ketoacidosis (DKA) was studied in newly diagnosed diabetic children aged 6-14 years, in the area of Parma, Italy, 8 years after an information program on DKA was introduced to teachers, students, parents, and pediatricians. Information was provided by displaying a poster with a few practical messages in 177 primary and secondary public schools. The pediatricians working in the same area were given equipment for the measurement of both glycosuria and blood glucose levels, as well as cards listing guidelines for the early diagnosis of diabetes, to be given to patients. A toll-free number was also provided. Clinical and laboratory features of 24 young diabetic patients diagnosed in the Parma area (group 1) were compared with those of 30 patients coming from two nearby areas in which no campaign for the prevention of DKA had been carried out (group 2). RESULTS: From 1 January 1991 to 31 December 1997, DKA was diagnosed in 3 children from group 1 (12.5%) and in 25 children from group 2 (83.0%) (chi 2 = 26.8; P = 0.0001). The three cases of DKA in group 1 were observed in 1991 (n = 1) and in 1992 (n = 2). No patients from the Parma area who had DKA were admitted to our unit after 1992. The duration of symptoms before diagnosis was 5.0 +/- 6.0 and 28.0 +/- 10.0 days (P < 0.0001), in groups 1 and 2, respectively, Metabolic derangements were less severe in patients of group 1 than in those of group 2. Hospitalization for the treatment of overt diabetes and for the teaching of self-management of the disease lasted 5.4 +/- 1.2 days in group 1 and 13.3 +/- 2.4 days in group 2 (P = 0.002). The total cost of the 8-year campaign was $23,470. CONCLUSIONS: The prevention program for DKA in diabetic children aged 6-14 years, carried out in the Parma area during the last 8 years, was successful. Thanks to this program, cumulative frequency of DKA in new-onset IDDM decreased from 78% during 1987-1991 to 12.5% during 1991-1997. None of the newly diagnosed diabetic children aged 6-14 years and from the Parma area were ever admitted to the hospital for DKA after 1992.

Metabolic control in children and adolescents with diabetes: experience of two Italian Regional Centers.

A survey on glycemic control in 201 diabetic children and adolescents, aged 0-18 years, was performed in two Italian Centers for Childhood Diabetes (Chieti and Parma). Mean HbA1c was 7.8+/-1.4 (range 4.8-13.3%; median 7.6%). With progression of diabetes duration, deterioration of glycemic control was observed (r=0.20; p< 0.002), more evident in girls than in boys, with peaks at 14 (8.9+/-2.0 vs 6.9+/-1.7%; p<0.05) and 16 years (9.5+/-1.4% vs 8.1+/-1.1; p<0.02). No differences were found in BMI values in boys or girls, or for insulin doses which were increased significantly in both sexes according to age (r= 0.33, p<0.04). The number of insulin injections did not influence glycemic control. Only one severe hypoglycemic episode was reported during the period of observation. This study demonstrates that modern management, continuous education and patient and family empowerment are effective in attaining excellent glycemic control without increasing the risk of hypoglycemia.

Ketoacidosis and hyperosmolarity as first symptoms of type 1 diabetes mellitus following ingestion of high-carbohydrate-containing fluids.

The concomitant occurrence of diabetic ketoacidosis and hyperosmolarity is reported in two children, as early symptoms of misdiagnosed type 1 diabetes mellitus. The precipitating factor for both severe metabolic abnormalities was the ingestion of a large amount of high-carbohydrate-containing fluids, a few days before admission. A similar situation has never been reported before in the literature. A successful therapeutic scheme is described.

The AGROBOT project.

The aim of this paper is to illustrate the AGROBOT project. This project was initiated to develop a complete robotic system for the production cycle of tomato plants in a greenhouse environment. The robot architecture is based on a vehicle carrying the picking arm (a six degrees of freedom anthropomorphic arm with a gripper/hand), the head with the two micro cameras (for the color stereoscopic vision system) and the VME rack for the complete control of the system. The head was purposely developed to permit complete visibility of the overall area. The vision system drives the head to point the path during navigation or to explore the plants looking for the work objects. The robot will be able to navigate between rows of plants, stop near each plant and identify the relevant objects (fruits or flowers) so as to be able to pick ripe tomatoes or spray anticryptogamic substances on flowers. Due to its flexible architecture, the system can be suited to operate on other kinds of cultivation or could be modified to perform other kinds of operations such as transplanting or packaging. Also the field of action could be different from greenhouses: changing from a wheeled locomotion system to a tracked system, the robot will be able to operate on particularly irregular surfaces. These features make this robotic system particularly adapted to replace human from tiring and harmful tasks or operating within adverse environment.

Robot-assisted microscope for neurosurgery.

We describe the implementation of a robotic arm connected to a neurosurgical operative microscope. A force feedback sensor drives the motors of the arm in response to the positioning of the microscope by the surgeon. Computer graphic techniques allow tracking of the current position of the microscope within the volumetric reconstruction of the brain. The integration of the prototype into the neurosurgical operating room is currently being evaluated. Preliminary comments on this experimental phase are offered.

[Vojta's seven postural reactions in the detection of neuromotor disorders in infants. Experience with 2382 subjects]. / Le sette reazioni posturali di Vojta come depistage delle alterazioni neuromotorie del lattante. Esperienza su 2.382 soggetti.

The Authors examined 2.382 babies who were between 4 and 6 weeks old using the seven postural reactions proposed by Vojta for neuromotor screening. They followed the progress of 2.295 (96,35%) babies up to the age of 1 year. 100% of the babies judged to be normal after the first visit were normal after a year. The Authors describe the evolution of the babies who were abnormal at the first visit, and clarify the results obtained with early physiotherapeutic treatment.
