Present invention is a system of blood glucose monitoring and intensive insulin therapy in a ICU for strict maintenance of normoglycemia which reduces intensive care and hospital mortality and morbidity of critically ill adult patients. The findings of present study also reveal factors determining insulin doses needed to maintain normoglycemia as well as the impact of insulin dose versus blood glucose level on the observed outcome benefits have been established. The invention provides a control system that adapts the flow of the insulin infusion based on insulin requirement calculated by blood glucose levels and clinical parameters such as history of diabetes, Body Mass Index, blood glucose level on admission, reason of ICU admission, time in the ICU, type and severity of illness, caloric intake, obesity, drugs affecting insulin sensitivity). This automated insulin monitoring systems significantly reduces the workload and human resource management problems for intensive insulin therapy in patients in the ICU.

A knee prosthesis, methods of implanting the prosthesis, method of treating arthritis of the knee, and a kit therefore are provided. The prosthesis answers many of the limitations of current knee prosthetic devices by providing a two-component (or alternatively, an optional three-component) device, as either a single structure, or as separate pieces. One of the components is constructed of low friction material, while the second is composed of a weight-dissipating cushioning material; the optional third component is constructed of low friction material. The prosthesis is initially attached to surrounding soft tissue in the knee by biodegradable sutures; it is held permanently in place by fibrous ingrowth into a porous collagen rim in the cushioning component. Major improvements provided by the present invention over currently available prostheses include minimal incisions, minimal or no bone cuts, minimal overall dissection (these improvements lead to shorter hospital stays and rapid rehabilitation and fewer potential for side effects), less prosthetic wear, greater longevity, fewer activity restrictions, able to be used on young, large, active patients, ease of revision, ease of conversion into a total knee arthroplasty if needed.

A patient care management system for assisting a physician in monitoring drug use by a patient. The system receives drug dispensation data for a drug, on the basis of which the system determines drug supply availability data. The drug supply availability data is indicative of periods of time during which the drug was available in non-duplicate supply, or in oversupply, or in insufficient supply. The periods of time are displayed with respect to a common time base. Each degree of supply availability is visually displayed via a graphical user interface using, e.g., a color coded scheme, so as to be distinguishable by a user. This allows a physician to rapidly assess over-consumption or compliance problems. Plural drugs may be monitored on a single display screen. The system may also be adapted to allow an prescribing physician to assess refill compliance, hospitalization periods and prescription drug costs.

Minimal Invasive Spine Surgery (MISS) as a surgical approach is increasingly utilized because of the advantages it offers over conventional spine surgery. The smaller incision results in decreased tissue damage, less blood loss, decreased hospital stay & faster postoperative recovery. The drawbacks of MISS are the long learning curve of working through a smaller incision, longer length of surgery, & potential higher complication rate due to compromised visual field. These limitations can be overcome by more effectively using imaging and navigational devices. The pedicle device simplifies the hardest part of MISS instrumented fusion of conventional pedicle screw insertion by introducing a percutaneous temporary device to locate and create the channel for later conventional pedicle screw implantation using available imaging techniques. This results in faster conventional pedicle screw insertion with precision, thereby decreasing implantation error and minimizing soft tissue injury and blood loss, as well as neurological, vascular, and dural injuries and complications.
