During the period of 4 years from May, 1981 to April, 1985, 71 cases of obstructing subinfundibular muscular bundles of the right ventricle in congential cardiovascular anomalies were diagnosed by cariac catheterization and angiography at Hanyang University. The finding of right ventricular angiogram and degree of the right ventricular outflow obstruction, clinical data, electrocardiographic data and hemodynamic data were correlated irrespectively. The summary of this article is as follows. 1) The age of patients was ranged from 1 to 22 years old with a mean age of 8 years old. There were 39 males and 32 females with M:F ratio of 1.2:1. The incidence of obstructing subinfundibular muscular bundles of the right ventricle in congenital cardiovascular anomalies was higher with increasing age. 2) The associated cardic anomalies were as follows: 40 cases (56%) of isolated ventricular septal defect(VSD), 13(18%) of tetralogy of Fallot physiology, 7(10%) of patent ductus arteriosus(PDA), 3(4%) of pulmonary stenosis, 1 aortic stenosis, 1 double outlet of right ventricle(DORV), 1 trilogy, 1 ostium secundum defect, etc. The incidence of VSD with or without other associated cardiovascular anomalies was 56 cases(79%) out of 71 cases. 3) Maximum systolic pressure gradient between proximal and distal chamber of the right ventricle were under 25 mmHg in 32 cases, between 25 and 50 mmHg in 13 and above 50 mmHg in 26. Pressure gradients of all 7 cases with PDA were under 25 mmHg. 4) Correlative assesment of angiographic manifestation(2 indicies:Diameter of right ventricular outflow tract(systolic phase)/diameter of tricuspid valvular annulus(diastolic phase)=OT/TV, Diameter of right ventricular outflow tract(systolic phase)/Length of right ventricular diaphragmatic surface(systolic phase)=OT/RV) according to pressure gradient, OT/Tv and OT/RV values were lower the increasing pressure gradient, between proximal and distal chamber of the right ventricle. These were reverse correlations but coefficients of correlation(r) were-0.49and -0.48. Therefore, the degree of right ventricular outflow obstruction could be predicted, using 2 indices of right ventricular angiogram in individual cases, but could not be calculated accurately. 5) This indicated that pressuer gradient was also affected by technical errors, variable cardic anomalies, development of sinusoid, age and the other factors. 6) We assumed that non-invasive Doppler echocardiography could be useful in making the diagnosis and follow up of the patient with obstructing subinfundibular muscle bundles in right ventricle.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.

OBJECTIVES: In order to devise the combination module transmitting bio signal and signal data remotely, as defect of wirewireless combination module was complemented by designing a single combination of wireless module and power supply module, a single system was implemented. METHODS: Currently in case of wireless transmission, it had various problems causing by some factors such as buildings, obstruction, and entanglement of wires and so on. In order to overcome problems of wireless transmission, a single combination module design was researched, which transmits vital signal and sign data using basic electric line installed in the inner building or between others. Even though it was also possible of wireless communication and the internet, in case of a power supply without them, it could be possible to transfer data to underground or top ground in the inner building without any special communication line. RESULTS: Bio signal data was transmitted through a power supply line, a noise problem occurred would be solved by the designed noise filter. The filter showed that noise was cut off about more than 90%. It was also confirmed that the used ECG signals was stably received on transmission experiment. An internal PCB antenna could make the system be wireless communication without the disclosure of an antenna. CONCLUSIONS: In this study, in order to implement a useful system transmitting bio signal and data through wire and wireless management for combination design of wireless module and electrical line module, bio signal transmission system was implemented by design of noise break filter circuit to reduce power noise and PCB internal antenna design.

Non-alcoholic fatty liver disease (NAFLD) is emerging as a world-wide health problem and is currently recognized as a hepatic manifestation of metabolic syndrome. It is an umbrella term to describe a wide range of diseases from simple steatosis to non-alcoholic hepatosteatosis (NASH) and NSAH-related liver cirrhosis. NAFLD is mainly associated with insulin resistance which allows increased free fatty acid (FFA) flux to the liver by increasing lipolysis from adipose tissue, triggering macrophage/immune activation, decreasing skeletal muscle glucose uptake, and increasing de novo lipogenesis. Increased FFA pool in the liver, in turn, increases lipotoxic intermediates, such as ceramides, diacylglycerols, and lysophosphatidylcholines, which are responsible for mitochondrial dysfunction and endoplasmic reticulum stress, resulting in inflammation of the liver. When inflammation is severe enough to affect stellate cells, hepatic fibrosis can be induced.

OBJECTIVE: To know whether nerve conduction study (NCS) could predict later development of carpal tunnel syndrome (CTS) in asymptomatic hands of the patients with unilateral CTS. METHOD: Thirty four patients with unilateral CTS were studied. Subjects were divided into groups with or without the delay of latency, based on the results of initial NCS of asymptomatic hands. After follow up for more than 6 months clinically and electrodiagnostically, the development of CTS in initially asymptomatic hands was compared between groups. RESULTS: At follow up, CTS was diagnosed in 83% of the subjects in the group with motor latency delay at first study, while it was diagnosed in 32% of the subjects in the group without motor latency delay. In the group with sensory latency delay at first study, CTS was diagnosed in 78% of subjects at follow up, whereas only 19% of the subjects developed CTS in the group without sensory latency delay. The incidence of CTS at follow up was significantly higher in the group with motor or sensory latency delay at first study. CONCLUSION: In unilateral CTS, latency delay in motor or sensory NCS of asymptomatic hands may suggest a greater risk of later development of CTS.

OBJECTIVE: To evaluate the benefit of digital infrared thermography imaging (DITI) and three-phase bone scintigraphy (TPBS) for detecting the post-hemiplegic complex regional pain syndrome (CRPS). METHOD: DITI and TPBS were done in 26 patients with post-hemiplegic CRPS clinically and 14 hemiplegic patients without CRPS as controls. Positive findings were interpreted when the affected hands were 1.0degrees C higher than those of unaffected hands in DITI system and pathological uptake in the regions of interest (hands without fingers-carpal bones, metacarpal bones and metacarpopharyngeal joints) in delayed phase of the TPBS. RESULTS: The sensitivities of DITI and TPBS to detect CRPS were the same to each other as 46.2%, and specificities were 85.7% and 100% respectively. Nineteen of 26 patients (sensitivity=73.1%) were interpreted as abnormal when at least one test showed a positive finding. As a result, an increased diagnostic strength was achieved. CONCLUSION: These findings suggest that the combination of TPBS and DITI can improve the diagnostic strength of post- hemiplegic CRPS.

PURPOSE: The purpose of this study is to evaluate the clinical and radiological results of the trochanteric flip osteotomy in cases of femoral head fractures. MATERIALS AND METHODS: Between May 2000 and January 2012, we evaluated 14 cases of femoral head fractures treated by trochanteric flip osteotomy in combination with the Kocher-Langenbeck approach after a minimum follow-up of one year. There were 13 men and one woman and the average follow-up period was 36.4 months. The clinical results were evaluated according to Merle d'Aubigne-Postel scores and the Thompson-Epstein scoring scale and the radiological results were evaluated according to time to union of fractures and osteotomy site. We also evaluated the incidence of complications. RESULTS: At the last follow-up, mean Merle d'Aubigne-Postel score was 16.4 and 11 cases out of 14 patients presented with good to excellent, two cases presented with fair, and one case presented with a poor clinical result according to the Thompson-Epstein scoring scale. Radiologically all cases achieved union of fractures and osteotomy site and the mean time to union of the osteotomy site was 7.9 weeks. Complications included one case of heterotopic ossification which did not disturb hip function, two cases of avascular necrosis of the femoral head, and one case of post-traumatic osteoarthritis. CONCLUSION: The trochanteric flip osteotomy in the case of a femoral head fracture showed good clinical and radiological results through good visualization and accurate reduction of the fracture site. However, conduct of further studies including larger number of patients is needed in order to evaluate the incidence of complications such as avascular necrosis of the femoral head.

Peripartum cardiomyopahty(PPCM) is an uncommon myocardial disease arising in the last month of pregnancy or within 5 months after delivery, in the absence of obvious cause and without prior evidence of heart disease. The risk of recurrence of PPCM is considered low when left ventricular size and function return to normal. But we experienced a case of peripartum cardiomyopathy recurred in subsequent pregnancy despite the return to normal heart size and function. This case was summarized here with a brief review of the related literatures.

OBJECTIVE: To compare the slip reduction rate and clinical outcomes between unilateral conventional transforaminal lumbar interbody fusion (conventional TLIF) and unilateral minimal invasive TLIF (minimal TLIF) with pedicle screw fixation for treatment of one level low-grade symptomatic isthmic spondylolisthesis. METHODS: Between February 2008 and April 2012, 25 patients with low-grade isthmic spondylolisthesis underwent conventional TLIF (12 patients) and minimal TLIF (13 patients) in single university hospital by a single surgeon. Lateral radiographs of lumbar spine were taken 12 months after surgery to analyze the degree of slip reduction and the clinical outcome. All measurements were performed by a single observer. RESULTS: The demographic data between conventional TLIF and minimal TLIF were not different. Slip percentage was reduced from 15.00% to 8.33% in conventional TLIF, and from 14.15% to 9.62% in minimal TLIF. In both groups, slip percentage was significantly improved postoperatively (p=0.002), but no significant intergroup differences of slip percentage in preoperative and postoperative were found. The reduction rate also not different between conventional TLIF (45.41+/-28.80%) and minimal TLIF (32.91+/-32.12%, p=0.318). CONCLUSION: Conventional TLIF and minimal TLIF with pedicle screw fixation showed good slip reduction in patients with one level low-grade symptomatic isthmic spondylolisthesis. The slip percentage and reduction rate were similar in the conventional TLIF and minimal TLIF.
