Abstract
OBJECTIVE To assess the insulin antibody (IA) response to human insulin (HI) therapy in women with gestational diabetes. RESEARCH DESIGN AND METHODS IAs were measured by a competitive radiobinding assay in 50 women with gestational diabetes before and during treatment with HI and after delivery. At delivery, 15 maternal-cord blood sample pairs were analyzed for IA. As a reference, we searched for IA in 25 new-onset type I diabetic patients, before and at 3, 6, and 12 months after insulin therapy. RESULTS Insulin autoantibodies (IAAs) were detected in 1 of 50 women with gestational diabetes and 4 of 16 type I diabetic patients (P < 0.05). At the end of pregnancy after 9.3 +/- 6.8 weeks on insulin therapy, 22 of 50 (44%) women with gestational diabetes became IA+ and 4 additional women were found to be positive 2 months postpartum. After 3 months on insulin, type I diabetic patients showed a higher rate of IA positivity (92%, P < 0.001). IA titers at the end of pregnancy were associated with the cumulative insulin dose (r = 0.29, P < 0.05). Postpartum, IA disappeared slowly in most IA+ women, but two women still showed IA 2 years after delivery Titers in cord blood were strongly related to those in maternal blood (r = 0.74, P < 0.01). The rate of adverse fetal outcome did not differ in IA and IA- mothers (27 vs. 40%, NS). CONCLUSIONS HI is immunogenic, and a short course of HI therapy induces IA in approximately 50% of women with gestational diabetes and 92% of type I diabetic patients. In women with gestational diabetes, insulin dose is slightly associated with IA titers. These IAs apparently cross the placenta. Fetal outcome does not differ according to the maternal IA status, and IAs disappear gradually after delivery but may remain positive for 2 years after delivery.

Abstract
The medical record is central to the management of patients. For people with a chronic disease their many records, held at different locations, often pose a problem. Electronic patient records have been discussed for a long time. This article reports on the paradigm of a portable computer-based patient record on a smart card. It describes the development of the chip card based medical information system for chronic diseases in ambulatory and hospital care. The system has been implemented, tested and evaluated. DIABCARD could demonstrate that for a speciality patient record the capacity and functionality of the existing card is sufficient. Finally, the perspectives of chip cards in health care are discussed.

Abstract
An intelligent decision support system for the analysis of home monitoring data and therapy planning in gestational diabetes is presented. The paper describes the integration of qualitative and quantitative reasoning modules within the DIABNET advisory system. The system kernel is a qualitative model of the physiological processes involved in the glucose metabolism of this type of diabetic patient. A causal probabilistic network (CPN) has been used to represent the qualitative model in order to manage uncertain and missing monitoring data. The DIABNET inputs are the patient's available ambulatory monitoring data, and the output is a dietary and insulin therapy adjustment that includes initiation of insulin therapy, quantitative insulin dose changes and qualitative diet and schedule modifications. Over periods of up to seven days, monitoring data are analysed by the CPN to detect any diet or insulin therapy items which may require modification. The qualitative insulin needs are translated into a quantitative proposal in line with the characteristics of the patient and the modification strategies usually used by doctors. The first evaluation of the system has been accomplished, the encouraging results of which are also presented.

Abstract
In order to further characterize women with islet cell antibodies (ICA) at the diagnosis of gestational diabetes (GDM), we aimed to compare titres and persistence as well as B-cell function with those of ICA+ first-degree relatives of Type 1 (insulin-dependent) diabetic subjects. Titres at detection of ICA were compared between 69 women with GDM and 53 relatives. Persistence of ICA positivity was investigated in 33 ICA+ gestational diabetic women and 39 relatives (mean follow-up: 13 months). Assessment of the acute insulin response, through an intravenous glucose tolerance test (IVGTT), was carried out in 9 ICA+ women with previous GDM and normal oral glucose tolerance, and their results were compared to those of a control group (9 women) and a group of 12 adult ICA+ relatives. In comparison with first-degree relatives, women with GDM had a higher ICA prevalence, especially with titres of < 20 JDF, and a similar persistence at follow-up. Women with ICA at diagnosis of GDM and normal oral glucose tolerance after pregnancy showed a decreased insulin response to glucose as compared to the control group. Results of the IVGTT closely paralleled those from adult ICA+ relatives. It is concluded that ICA+ gestational diabetic women share with ICA+ first-degree relatives of Type 1 diabetic subjects metabolic and immunologic disturbances.

Abstract
Polyarteritis nodosa (PAN) is a systemic necrotising vasculitis which affects middle calibre arteries and which has a tendency to form aneurysms. It may appear as one of a great variety of clinical forms depending on the vascular territory afflicted. Almost any organ may be involved although the lung is usually unaffected. Neurological manifestations are very frequent in this disease (global incidence being around 80%), especially at the peripheral nervous system level. Multiple mononeuritis is the most usual manifestation classically associated with this type of vasculitis, but it may also appear as distal sensorimotor polyneuropathy, this being its most infrequent form of presentation. The presence of nerve conduction blocks has also been recently described, usually associated with demyelinating processes. However peripheral nerve affectation in vasculitis has its origins in small ischaemic infarcts in the sensorimotor conduction fibres. It may well be that segmentary demyelination and axonal degeneration reflect different levels of ischaemic damage.

Abstract
DIABCARD provides the specification for the core of a Chip Card Based Medical Information System (CCMIS) for the treatment of patients with chronic diseases. It will provide an instrument for assessing health care services, improve the links between health care providers and set up communication between the different levels of health care. It will therefore improve the quality of care and thus the life of patients with chronic diseases. DIABCARD concentrates on diabetes at the moment, the concept of the diabetes chip card will, however, be extendable to other chronic diseases.

Abstract
This poster describes a system to analyze self-monitoring data of gestational diabetic patients, for obtaining an assessment of their metabolic control with the final goal of supporting decision-making in therapy adjustment. The system is able to manage incomplete data and to make temporal reasoning under uncertainty, the two most important constraints when analyzing ambulatory monitoring data. Two different formalism have been used to represent and manage the knowledge: a dynamic Bayesian network and a production system based on rules. The outcomes provided by the whole system are: information on possible patient transgressions of the prescribed treatment and recommendations of treatment adjustments.

Abstract
Twenty-four women with high circulating prolactin became pregnant on 39 occasions, of which 32 ended in delivery. Sixteen patients showed radiological evidence of pituitary tumour, 6 exhibited a normal CT and 2 had an empty sella. The pregnancies were induced in 4 patients after successful pituitary surgery, in 3 after surgery and medical treatment, and in the rest by bromocriptine (16) long-acting repeatable bromocriptine (1) and methergoline (1). No major complications related to hyperprolactinaemia or its treatment were observed during pregnancy in the patients or offspring. Prolactin after pregnancy was lower than before (basal 95 micrograms/l, after 1st pregnancy 38 micrograms/l P < 0.002, after 2nd pregnancy 24 micrograms/l P < 0.005 compared to basal prolactin); this prolactin reduction tended to be greater in the 9 multiparous patients, but did not attain statistical significance, probably because the number of multiparous patients was too small. A new empty sella developed after delivery in 4 women and persisted in another 2, all of which were medically treated; prolactin fell in all 6 cases normalizing in 3; 4 of these patients had undergone two or more pregnancies. The mean period of follow-up from the last pregnancy was 41.6 months (8-101). These data suggest that pregnancy may hasten a tendency to spontaneous improvement of hyperprolactinaemia, and multiparity may be beneficial in this way.

Abstract
Although gestational diabetes may have serious consequences for both mother and fetus, it is usually symptomless. The diagnosis can be missed unless all pregnant women are screened to determine those who need a full oral glucose tolerance test. When gestational diabetes is diagnosed, it is essential to (1) achieve euglycemia with diet and, if needed, insulin and (2) monitor for potential complications. Glucose tolerance must be reevaluated in the post-partum period and periodically thereafter to detect continuing intolerance or diabetes.

Abstract
BACKGROUND There is a certain degree of peripheral cell resistance to insulin in the physiopathology of gestational diabetes. These disturbances may persist following pregnancy giving place to secondary hyperinsulinism. Insulin exerts a trophic action on the ovary and favors the production of androgens. The aim of this study was to verify whether the patients diagnosed of gestational diabetes present androgenic alterations following pregnancy. The existence of a correlation between the values of insulin and androgens was analyzed. METHODS Fifty-one patients were studied. The study group (n = 297) was composed of patients diagnosed of gestational diabetes during their last week of pregnancy. The control group (n = 24) included patients with normal carbohydrate tolerance. The basal values of insulin, glucose, androstenedione, testosterone and SHBG were determined in a postmenstrual phase. RESULTS Insulin was found to be higher in the study group (78.1 +/- 32.9 pmol/1 vs 63.0 +/- 27.6 pmol/1) although the differences were not significant. The insulin/glucose ratio was significantly higher in the study group (18.1 +/- 8.0 vs 13.9 +/- 7.7; p less than 0.05). Basal insulin and the insulin/glucose ratio were comparable among the obese and non obese patients of both groups. The remaining parameters studied dit not present any significant differences. No significant associations were observed between the values of insulin and insulin/glucose with the androgenic hormonal parameters. CONCLUSIONS No elevated androgenic profile was observed in the women with previous gestational diabetes. The use of insulin and insulin/glucose values as indicators of insulin resistance did not demonstrate any correlation with the androgenic parameters.

Abstract
Serum fructosamine was measured in 569 samples of pregnant women without gestational diabetes. We defined abnormal fructosamine as mean + 2SD, and analysed its potential value to detect patients with gestational diabetes diagnosed with current screening criteria. We found serum fructosamine to be an insensitive parameter: Measured at the time of a positive 50 g glucose screening, SF would have detected 4/48 gestational diabetes.

Abstract
In experimental diabetes and after the administration of beta-hydroxybutyrate and non-esterified fatty acids (NEFA), an increase in circulating immunoreactive somatostatin (IRS) has been described. Both ketones and NEFA are raised in diabetic ketoacidosis. Therefore, we decided to investigate 10 patients in diabetic ketoacidosis by measuring, on admission and throughout the initial 24 hours of therapy, circulating levels of IRS, beta-hydroxybutyrate, acetoacetate, triglycerides, blood glucose, pH and NEFA. Fluids and insulin were administered IV following a previously established protocol. Nine patients showed abnormally high levels of circulating IRS. When compared with a group of controlled insulin-dependent diabetic patients, basal IRS was high (111 +/- 15 vs 28 +/- 3 pmol/l), and remained elevated for at least 24 h despite clear improvement of metabolic status. On admission we also found elevated levels of NEFA (1.04 +/- 0.2 mmol/l), triglycerides (4.7 +/- 1.1 mmol/l), beta-hydroxybutyrate (22.1 +/- 4mmol/l), and acetoacetate (4.8 +/- 1.1 mmol/l). A significant correlation was found initially between IRS and NEFA (p less than 0.01). We conclude that circulating IRS is high in most cases of diabetic ketoacidosis. The mechanism behind this hypersomatostatinaemia could be related to the abnormalities of lipid metabolism which occur in diabetic ketoacidosis.
