1.  Healing enhancement of chronic venous stasis ulcers utilizing H-WAVE® device therapy: a case series 
Cases Journal  2010;3:54.
Introduction
Approximately 15% (more than 2 million individuals, based on these estimates) of all people with diabetes will develop a lower-extremity ulcer during the course of the disease. Ultimately, between 14% and 20% of patients with lower-extremity diabetic ulcers will require amputation of the affected limb. Analysis of the 1995 Medicare claims revealed that lower-extremity ulcer care accounted for $1.45 billion in Medicare costs. Therapies that promote rapid and complete healing and reduce the need for expensive surgical procedures would impact these costs substantially. One such example is the electrotherapeutic modality utilizing the H-Wave® device therapy and program.
It has been recently shown in acute animal experiments that the H-Wave® device stimulation induces a nitric oxide-dependent increase in microcirculation of the rat Cremaster skeletal muscle. Moreover, chronic H-wave® device stimulation of rat hind limbs not only increases blood flow but induces measured angiogenesis. Coupling these findings strongly suggests that H-Wave® device stimulation promotes rapid and complete healing without need of expensive surgical procedures.
Case presentation
We decided to do a preliminary evaluation of the H-Wave® device therapy and program in three seriously afflicted diabetic patients. Patient 1 had chronic venous stasis for 6 years. Patient 2 had chronic recurrent leg ulcerations. Patient 3 had a chronic venous stasis ulcer for 2 years. All were dispensed a home H-Wave® unit. Patient 1 had no other treatment, patient 2 had H-Wave® therapy along with traditional compressive therapy, and patient 3 had no other therapy.
For patient 1, following treatment the ulcer completely healed with the H-Wave® device and program after 3 months. For patient 2, by one month complete ulcer closure occurred. Patient 3 had a completely healed ulcer after 9 months.
Conclusions
While most diabetic ulcers can be treated successfully on an outpatient basis, a significant proportion will persist and become infected. Based on this preliminary case series investigation we found that three patients prescribed H-Wave® home treatment demonstrate accelerated healing with excellent results. While these results are encouraging, additional large scale investigation is warranted before any interpretation is given to these interesting outcomes.

2.  Age-related increases in parathyroid hormone may be antecedent to both osteoporosis and dementia 
Background
Numerous studies have reported that age-induced increased parathyroid hormone plasma levels are associated with cognitive decline and dementia. Little is known about the correlation that may exist between neurological processing speed, cognition and bone density in cases of hyperparathyroidism. Thus, we decided to determine if parathyroid hormone levels correlate to processing speed and/or bone density.
Methods
The recruited subjects that met the inclusion criteria (n = 92, age-matched, age 18-90 years, mean = 58.85, SD = 15.47) were evaluated for plasma parathyroid hormone levels and these levels were statistically correlated with event-related P300 potentials. Groups were compared for age, bone density and P300 latency. One-tailed tests were used to ascertain the statistical significance of the correlations. The study groups were categorized and analyzed for differences of parathyroid hormone levels: parathyroid hormone levels <30 (n = 30, mean = 22.7 ± 5.6 SD) and PTH levels >30 (n = 62, mean = 62.4 ± 28.3 SD, p ≤ 02).
Results
Patients with parathyroid hormone levels <30 showed statistically significantly less P300 latency (P300 = 332.7 ± 4.8 SE) relative to those with parathyroid hormone levels >30, which demonstrated greater P300 latency (P300 = 345.7 ± 3.6 SE, p = .02). Participants with parathyroid hormone values <30 (n = 26) were found to have statistically significantly higher bone density (M = -1.25 ± .31 SE) than those with parathyroid hormone values >30 (n = 48, M = -1.85 ± .19 SE, p = .04).
Conclusion
Our findings of a statistically lower bone density and prolonged P300 in patients with high parathyroid hormone levels may suggest that increased parathyroid hormone levels coupled with prolonged P300 latency may become putative biological markers of both dementia and osteoporosis and warrant intensive investigation.
