Development of Biosignal Telemonitoring System Based on HL7 and MFER Standard / 대한의료정보학회지

OBJECTIVE: We developed a biosignal telemonitoring system which is based on HL7 and MFER standard. METHODS: For the communication of waveform data (ECG, EEG etc.) we adopted MFER(Medical waveform description Format Encoding Rules) standard and HL7(Health Level 7). MFER is a standard for encoding waveform biosignal such as ECG, EEG and so on. HL7 is a standard for electronic data communication between two different information systems. RESULTS: The telemornitoring system consists of an HL7 interface gateway and a central repository. The HL7 interface gateway has three modules of an MFER analyzer, an HL7 message generator, and a file sender. The central repository is a central database combined with an HL7 archiver. CONCLUSION: Through this study we might conclude that the proposed system can be a promising model for telemonitoring system in healthcare environment.

Histological and Histochemical Follow-up of the Resurfaced Heel Pad, Reconstructed by Free Flaps / 대한정형외과학회잡지

The development of the microvascular surgery revolutionalized the reconstructive surgery of the lower ext tremity. Especially, the defects of the heel and sole, the weight bearing area, were quite difficult and complicate to reconstruct by conventional methods. Many papers reported successful resurfacing the heel pad by free cutaneous or myocutaneous flaps. However, only few reports were conceming the late results of the reconstructed free flaps. The authors studied the histological and histochemical changes of the free flaps under the weight bearing stress in 10 cases. 1. The authors reconstructed 10 cases of the heel pad defects by dorsalis pedis free Aaps (5 cases) and latissimus dorsi myocutaneous flaps(5 cases). 2. Before transfer, the homy layer was very thin(about 0.16–0.2 mm) and had an arrangement of basket-weave pattem in both flaps. Until one year after transfer, this layer was wom out (0.02–0.08mm) However, after one year, this layer became thick (0.05–0.7 mm) and the arrangement was compact in both free flaps. 3. The granular and prickle cell layers were also increased in thickness after one year. 4. In the suprabasilar area, friction blisters were observed before one year, especially in latissimus dorsi myocutaneous flap. However, they slowly disappeared after one year and then the epidermis was stabilized. 5. In the dermis, the contents of the amyloid and acid mucopolysaccharides were increased up to the level of those of the normal heel pad in both flaps. 6. As a conclusion, the transferred free flaps were in distress before one year. But after one year, they began to adapt well histologically and histochemically to the weight bearing stress.

A Clinical Study of Trochanteric Fracture / 대한정형외과학회잡지

Trochanteric fractures frequently occur in elderly patients and are associated with other fractures due to increase in severity of accidents. Because of complications in elderly patients, trochanteric fractures are treated with open reduction and internal fixation with increasing frequency. The authors treated 41 cases of trochanteric fractures of the femur in the year 1977 through 1980 at the Department of Orthopedic Surgery, Jeonbug National University. The resuts were as follows: 1. Of 41 cases, 35 cases were males and 6 cases females. In males most occurred at 60's and in females at 70's. 2. The most common cause of the fracture was slipping or fall down. 3. In Tronzo classification, the type I was most commmon. 4. 5 cases were treated conservatively and 36 cases with open reduction and internal fixation. 5. The mean duration of bony union was 16.4 weeks and no differences were noticed in the cases treated with open reduction and internal fixation. 6. Satisfactory results were obtained in 91.7% of operative treatment and in 80% of non-operative treatment. 7. From these results, it was concluded that operative treatment of trochanteric fracture had more advantages of improvement of function and less complication than those of non-operative treatment.
