Tibialis anterior muscle herniation is the most common type of skeletal muscle herniation of the lower legs. The treatment of muscle herniation relies on the patient's symptoms. For patients with chronic large fascial defects, fascial grafting with synthetic mesh can be considered. In this case of a patient who was exposed to excessive strain on his lower legs during a military training program, the use of a secure repair technique with synthetic mesh was required. This paper presents a case of tibialis anterior muscle herniation that was treated successfully with a monofilament knitted polypropylene mesh covered by the tibialis anterior fascia. The advantages of this technique include early rehabilitation and an early return to work. No significant difference in the clinical results compared to other methods were observed and there were no complications. The military training program appeared to have aggravated the patient's symptoms of tibialis anterior muscle herniation. On the other hand, larger scale study will be needed to determine if this program actually affects the clinical outcomes.

Although intramedullary nailing is mostly used in the management of fractures in the long bone shaft, plate fixation is still alternative option in periprosthetic or metaphyseal fractures. For the rigid fixation during plating, sometimes we need wiring. Many surgeons experience slippage of wire resulting in loss of rigid fixation because plate and wire is so slippery and the diameter of bone is changing by level especially in the metaphyseal area. Wiring plate(CHO plate) was designed to prevent slippage. This plate has transverse holes for wires between screw holes on traditionally used dynamic compression plate. Sixteen fractures of long bone shaft were fixed with wiring plate and 11 cases which were followed up for more than one year were evaluated. There were periprosthetic fractures(4 cases), spiral or butterfly fractures(4 cases) and fractures of poor bone quality(two cases of malignancy and one case of osteoporosis). Nine cases were successfully reduced and the healed without loss of fixation. In two cases, delayed union and nonunion were observed due to wire breakage with plate loosening. Preliminarily, wiring plate fixation can be used for the periprosthetic fracture and one of alternative option in butterfly or spiral fracture and fracture in osteoporotic bone or pathologic fracture.

BACKGROUND: Previous studies have indicated adenosine triphosphate (ATP) is as potent coronary vasodillator as adenosine (A). We designed this study to compare the vasomotion of coronary artery (CA) between the infusion of ATP and that of A (1). METHOD AND RESULTS: Ten patients with normal CA (6 male and 4 female) age ranging from 41 to 74 years (57+/-11) were studied at LAD and RCA for measurement of coronary flow reserve (CFR), time to maximum effect (Tmax), time to baseline (TBL) in CA during ATP and A infusion. Tmax was achieved earlier with ATP than A, and these results suggest that maximum vasodilation occurs faster with ATP. Side effect profile was similar in 2 patients with mild chest pain with ATP and A. CONCLUSION: Since it has appeared that vasodilatory effect of ATP was comparable to A which has been used in pharmacological stress test in many diagnostic modalities, ATP can be used safely in many clinical setting where A has been used.

BACKGROUND: Glucose intolerance and diabetes mellitus are frequently observed in chronic liver disease. However, the causal relationships between these two are difficult to prove. Chronic hepatitis B infection, which is prevalent in Korea, is thought to be a good model to study the natural history of abnormal glucose metabolism in chronic liver disease because many patients with chronic hepatitis B infection eventually progress to liver cirrhosis. METHODS: In order to evaluate glucose metabolism in chronic hepatitis B infection, we did intravenous glucose tolerance test in patients with chronic hepatitis B and age, sex and body mass index matched controls and compared the first phase insulin response and glucose disappearance rates between 2 groups. RESULTS: Patients with chronic hepatitis B showed lower glucose disappearance rate and higher plasma insulin and C-peptide area (0-10min after iv glucose) than controls. Patients with decreased glucose disappearance rate had higher AST level and decreased plasma C-peptide area (0-10min). CONCLUSION: Most of the patients with chronic hepatits B infection is associated with insulin resistance and compensatory increase in the first phase insulin secretion. Inadequate insulin secretion may contribute to decreased glucose disappearance rate in these patients.

As wireless network technology and various mobile communication equipments have widely used and rapidly developed, many research workers are studying about a measurable system for several medical data or bio-signals, such as electrocardiogram, pulse-oximetry and so forth, by wireless. And, even generic people who are in a good state of health as well as patients in the hospital, whose concern and care about healthcare has increased greatly, so many research workers are studying about Ubiquitous Healthcare of new technology. This technology will offer natural medical services freely in anywhere and in a quiet way, even if people can not go to hospital. Our research made a possibility to measure environment data in each infant incubator by using temperature and humidity sensor, prior to measure directly bio-signals of patients. Each sensor was composed of wireless network based on TinyOS, and that wireless network connected to Personal Digital Assistants(PDA). So we were studied about telemetry system by using wireless sensor network. It was researches about telemetry system to measure environment data in infant incubator before, by web-based RF modules. But they has problems that incubator's movement restriction by wire, wire net's limitation. We solved these problems by organizing wireless sensor network that connected together sensors and measurement devices. This wireless sensor network organization, based on TinyOS, is possible to receive sensor's data of long distance by a relay station and to save power. In future, this network will be basic of Ubiquitous Healthcare as well as medical information system in hospital.

OBJECTIVE: A sleep apnea is the most frequent symptom among sleep disorders. As the number of aged people are increasing, research activities are also increasing to monitor sleeping disorders of the elderly who lives alone. We proposed a new processing algorithm to measure the quantity of breaths accurately. METHODS: We improved the conventional center-of-mass method and further apply the projection profile method. RESULTS: In this study a system that can monitors respiration non-invasively and automatically, by identifying the movement of the chest and abdomen using image processing technique during sleep, was implemented. We can see breathing status in real time based on the acquired breathing waves. To verify the designed system, the values from the polysomnography were compared and analyzed to validate the system accuracy. As a result, the mean accuracy is 96%. CONCLUSION: We can simply monitor the sleep apnea with no sleep interferences.

BACKGROUND: Pneumococcus is the most common cause of acute otitis media, community acquired pneumonia and invasive bacterial diseases in children. Ninety serotypes have been identified, and the distribution differs according to geographic area and ages. The 7 valent pneumococcal protein conjugate vaccine is used widely. To evaluate the efficacy of the vaccine, it is essential to investigate the distribution of the pneumococcal serotypes. MATERIALS AND METHODS: The serotypes and antibiotic resistance of the pneumococcus isolated from 308 patients at Shinchon Severance hospital from September of 2001 to July of 2005 were analyzed. RESULTS: The pneumococcci were isolated mostly from sputum and blood, and ear discharge in the descending order. Serotyping was possible in 265 cases, and the distribution of serotypes were 19F (16.2%), 19A (12.8%), 23F (8.7%), 6B (7.9%), and 6A (7.2%). Fifty two cases were isolated from those patients less than 16 years of age and the distribution of serotypes was 19F, 19A, 23F, 14, 6B, 6A and 4. Resistance to penicillin was 64.6% in all cases and 67.3% in children. The more common serotype showed the higher rate of penicillin resistance. Multi-drug resistance was demonstrated in 64.7%. Forty three percent of the total identified serotypes were included in the 7 valent pneumococcal conjugate vaccine. And 61.5% of the serotypes identified in children were included in the vaccine. CONCLUSION: The 7 valent vaccine may be used effetively in Korea. But, further study is needed to address serotype switching after the use of the protein conjugated vaccine, which has been reported in other countries.
