Early diagnosis and treatment of heterotopic ossification (HO) is essential to the prevention of complications. It is difficult to diagnose HO in its initial phase because non-specific clinical manifestations, laboratory findings and imaging findings of immature HO may mimic other diseases such as cellulitis, osteomyelitis, thrombophlebitis, deep vein thrombosis and local infection with abscess. We experienced two cases of HO, which were misdiagnosed as pyomyositis at first by clinical signs and MRI findings indicating the deep infection; the extensive intramuscular ossification appeared later on. We observed an increase of C-reactive protein and creatine kinase followed by the elevation of alkaline phosphatase with abnormal triphasic bone scan. The trajectory of these biomarkers was analyzed to get more insight into the early stages of HO along with the imaging findings. Although our cases cannot be generalized as typical of immature HO, they clearly demonstrate that the change of specific biomarkers with a careful history taking and physical examination should be noted to detect HO as early as possible while avoiding confusion with other mimicking conditions.

To observe the prognostic influences of the cardiac rehabilitation (CR) program in Korean acute myocardial infarction (AMI) patients during the first year after an occurrence of the disease.
A total of 141 AMI patients who underwent percutaneous coronary intervention (PCI) were recruited consecutively for this study and divided into the CR group and the control group. The CR group completed the phase 2 CR program in the hospital for a period of 6-8 weeks and maintained self-exercise in their community by exercise prescription for a year after AMI. We performed a prospective comparison of the patients' demographic data, high sensitive C-reactive protein (hs-CRP) level after the 4-month CR program, and the rate of recurrence (AMI, re-hospitalization, positive coronary angiogram, needed revascularization procedure, or death) between the two groups.
Compared to the control group (0.33±0.48 mg/dl), the hs-CRP level was lower in the CR group (0.18±0.32 mg/dl) after 4 months of exercise. The recurrence rate was lower (10%, 7/69) in the CR group, compared to the control group (24%, 17/72, p<0.05). The number of disease-free days was larger in the CR group (354±38.34), compared to the control group (316±99.96, p<0.05). In a comparison of statistical methods used for testing the equality of two survivor distributions, the CR group showed a lower recurrence rate than the control group (p<0.05).
Participation in the CR program designed for AMI patients who underwent PCI-induced normalization of the serum hs-CRP level and lowering of the recurrence rate by 14% during the first year.

Objective: To evaluate effects of gabapentin in post-stroke reflex sympathetic dystrophy (RSD).
Method: To 20 RSD patients after stroke, gabapentin was administrated. We started medication with 300 mg per day and increased dosage by 300 mg per two days up to maximum 900∼1,200 mg. We evaluated RSD symptom severities with hand pain, hand swelling and shoulder pain before gabapentin administration. Severity of each symptoms was graded and scored (0: no pain/swelling, 1: mild, 2: moderate, 3: severe). Severities of RSD symptoms were reevaluated on every dose increasing and on 1 week, 2 weeks and 4 weeks later after administrating maximum dosage. We defined as no effect group didn't have any improvement in symptom severity score in comparison with baseline score. Medications other than gabapentin were administrated in no effect group.
Results: Among 19 subjects whom we could follow-up, 4 subjects were defined as no effect group. 15 (78.9%) subjects showed improvement in symptom severity score. Statistically significant symptom improvements were observed after 4 weeks in comparison with baseline in hand pain and shoulder pain (p=0.000). From gabapentin 300∼600 mg dosage, hand and shoulder pain showed significant pain decrease. Improvement of hand edema was observed after 4 weeks, but it was statistically insignificant.
Conclusion: We conclude the gabapentin is effective for RSD pain, however further control study is required. (Korean Acad Rehab Med 2002; 26: 502-507)
