An elimination-absorber monitoring system addresses diaper-monitoring problems with a unique, low cost, multi-layer disposable sensor structure that absorbs small volumes of urine, yet allows most urine volume to flow unimpeded through it, and into the diaper below. When connected with a reusable, miniature monitor/indicator unit, the sensor presents a clear and on-going change of measurement condition upon experiencing a rapid influx into the diaper of a significant volume of urine, and/or upon a significant reduction in the available absorbency of the diaper's top surface. The sensor additionally provides recessed, protected elements for similarly presenting a clear and on-going change in measurement condition upon experiencing the presence of fecal matter. Further provided is the monitor unit employing narrow, widely-spaced, fast rise-time, fast transition-time pulses for conductivity measurement and alarm activation. The monitor and sensor are interconnected and attached to a diaper by particularly effective and unique means, and the monitor is equipped with a highly intuitive and convenient control interface, as well as improved assemblies for the transmission of audible and visual alarm indications. Also described is a convenient test-strip device which, when connected to the monitor/alarm unit of the system, can selectively simulate either a soiled or unsoiled elimination-absorber/sensor for test, caregiver-training or demonstration purposes.

The present invention provides methods of treatment of patients suffering from the complications of blood sugar disorders: diabetic peripheral neuropathy and diabetic nephropathy by administration of IGF-1 via protein therapy or gene therapy. It relates to methods of treating an individual having a diabetic disorder or a hyperglycemic disorder, comprising administering to the individual an effective amount of a DNA vector expressing IGF-1Eb or IGF-1Ec in vivo or an effective amount of at the IGF-1Eb or IGF-1Ec protein in the early hyperalgesia stage or in patients that have advanced to the hyposensitivity stage. Treatment at the early hyperalgesia stage prevents subsequent hyposensitivity with increases or maintenance of sensory nerve function. IGF-1Eb or IGF-1Ec treatment also increases muscle mass and improves overall mobility, which indicates a treatment-related improvement in motor function. Treatment with IGF-1Eb or IGF-1Ec at the hyposensitivity stage reverses hyposensitivity and improves muscle mass and overall health. Systemic IGF-1 provides a therapeutic modality for treating hyposensitivity associated with DPN. In addition, IGF-1Eb or IGF-1Ec provides a therapeutic modality for treating diabetic nephropathy. IGF-1Eb or IGF-1Ec improves renal function as evidenced by a modulation in serum albumin concentration and a reduction in urine volume and protein levels. IGF-1Eb or IGF-1Ec also reduces diabetic glomerulosclerosis.
