Child injury intensive monitoring system.

A system for the acquisition and recording of child injuries is described. This computer-based system is designed for implementation in three stages. Each successive stage covers wider geographical areas and provides more comprehensive facilities.Stage 1 collects basic identification information on injured children. It provides an intensive monitoring service which alerts the agencies properly concerned with child abuse to repeated or suspicious injury cases. Misleading or suppressed information increases rather than limits the precision of diagnosis. More comprehensive details of those children thought to be at risk are collected when stage 2 is introduced. The printed results of the processing of these details are circulated to certain authorized users, and they are organized for rapid information retrieval. A central office which receives a weekly copy of this cross-referenced file provides a 24-hour information service.In stage 3 a register containing fully structured, standardized case reports will be established. We believe that this system ensures medical confidentiality and respects the rights of parents and children.

Hypoglycaemia after pancreas transplantation: usefulness of a continuous glucose monitoring system.

BACKGROUND: After pancreas transplantation (PTx) some patients report occasional symptoms of hypoglycaemia and at times, serious hypoglycaemia. Continuous blood glucose monitoring (CBGM) allows determination of the daily glucose profile and detection of unrecognized hypoglycaemia. The aims of our study were to determine the incidence of hypoglycaemia in PTx and evaluate whether the use of CBGM helps to detect unrecognized nocturnal hypoglycaemia. PATIENTS AND METHODS: We studied 12 patients (six males) with normal functioning PTx and kidney transplantation for more than 3 yr, with systemic drainage of endocrine secretion and stable immunosuppression. A 24-h CBGM using a microdialysis technique (GlucoDay, A. Menarini Diagnostics, Florence, Italy) was performed in all the patients. RESULTS: Three patients had asymptomatic recorded glucose levels below 3.3 nmol/L during the nocturnal period (01:00-07:00 hours) with the glucose levels during these episodes being 2.6, 2.5 and 2.5 nmol/L, and the duration of nocturnal hypoglycaemia being 27, 62 and 93 min, respectively, rising spontaneously without intervention. Patients with hypoglycaemia presented lower glycosylated haemoglobin levels when compared with those not presenting hypoglycaemic episodes, although basal glucose and insulin levels and insulin antibody titres were similar. In one of the three patients presenting hypoglycaemia CBGM was re-evaluated after including an extra snack at bedtime, with subsequent normalization of the blood glucose profile being observed. CONCLUSION: Unrecognized nocturnal hypoglycaemia is relatively frequent in patients with PTx and 24-h CBMG may be useful to detect these episodes.

A cotside microcomputer monitoring system for use in the neonatal intensive care unit.

A dedicated cotside microcomputer unit is described. It is designed to collect and to display graphically all continuously recorded variables from an infant in a neonatal intensive care unit. The data are collected from existing monitoring equipment and the graphical displays demonstrate both short and long term trends in data. In addition, the system allows data collected intermittently to be entered on a simple keyboard and to be displayed on plots that are time-correlated with the on-line data displays. A permanent record of the monitoring interval may be generated and the facility for closed-loop control of the partial pressure of arterial oxygen is being developed for integration into the system.

Newly developed circulating blood volume-monitoring system and its clinical application for measuring changes in blood volume during hemofiltration.

Blood and ultrafiltrate electrical resistivities were continuously monitored during hemofiltration. By substituting these values into a previously developed equation that was modified by the authors, the hematocrit value was determined; and blood volume change was obtained from the change in this value. The following facts were discovered as the result of monitoring the blood volume change during treatment: When the body position was changed from the reclining to the sitting position, the blood volume decreased by 4.2 +/- 0.3%. With the body water removal rate kept constant, the body position recumbent, and the subject fasted, the blood volume gradually decreased. However, when the position was changed from reclining to sitting for food intake and once more returned to the supine position after the meal, the blood volume was greatly affected by the change in position and the food intake.

Ambulatory electrocardiograms obtained by Holter monitoring system in patients with permanent demand pacemakers.

Ventricular inhibited demand pacemakers (VVI) were implanted in 27 patients with complete A-V block and pacemaker arrhythmias were analyzed by Holter system ambulatory electrocardiograms and conventional electrocardiograms. With Holter ECG, 13 patients showed myopotential inhibition, 5 patients had sensing failure and premature ventricular contractions (PVC) were observed in all patients. On the contrary, myopotential inhibition and sensing failure were not detected by conventional ECG and the detection rate of PVC was only 30%. The transient recovery of A-V conduction was observed in 14 of 27 patients with Holter ECG, but was not detected by conventional ECG. The Holter system ambulatory electrocardiogram clearly demonstrated the complex cardiac arrhythmias. Therefore, it is useful for monitoring arrhythmias caused by VVI pacemakers.

The influence of artificial cutoff on a monitoring system and the water quality of the Keelung River.

The purpose of this study was to design a water quality monitoring network for the Keelung River in order to evaluate the effects of artificial cutoff across two bend channels. A steady-state water quality model was used to simulate the BOD and DO curves. The Kriging theory was applied to select the optimal locations for a water quality monitoring network. The sampling frequency was determined by the coefficients of variation of water quality and by considering the significance level and confidence interval. After calibration and verification of the water quality model, the model was applied and the simulation results indicated that the values of DO in the new channel would be higher than those of the old channel reaches. The critical point of the oxygen sag curve would shift to the mouth of river under O75 low-flow conditions, and the BOD values in the new channel would also slightly increase. The results further indicated that more monitoring stations would be needed in the downstream reaches.

Trophic and growth-regulating mechanisms in the central nervous system monitored by intracerebral neural transplants.

In vitro studies have demonstrated the presence of nerve growth factor (NGF) and other neurotrophic factors in the mammalian central nervous system (CNS). This paper reviews a series of experiments in which the intracerebral neural grafting technique was used to monitor the in vivo expression of such neurotrophic factors and the changes induced by denervating lesions, with the hippocampal formation as a model. Neonatal or adult sympathetic ganglionic neurons, and fetal septal cholinergic neurons, were grafted into or adjacent to the hippocampal formation in adult rats, and the effect of removal of the major afferent inputs (i.e. the septal, commissural or entorhinal inputs) on neuronal survival and fibre outgrowth was assessed histochemically or biochemically. Damage to the septohippocampal (partly cholinergic) pathway had a dramatic effect on survival and fibre outgrowth from neonatal and adult sympathetic ganglionic neurons, and increased the survival of both cholinergic and noncholinergic neurons in the fetal septal grafts. These effects were specific for lesions of the septohippocampal system (fimbria-fornix transection or medial septal lesions), and were not seen after transection of the entorhinal perforant path or the commissural system. It is proposed that neurotrophic factors in the hippocampal formation are under some type of regulation from the afferent inputs, and that removal of the septal afferents, in particular, will increase the availability of NGF or an NGF-like factor from the denervated target. This mechanism may play a normal role in the induction and regulation or regeneration and compensatory collateral sprouting from the remaining afferents in partially denervated brain regions.
