This is a follow up study on 124 cases of primary total hip arthroplasty with Harris-Galante porous-coated acetabular component with the line-to-line technique, performed at the Department of Orthopaedic Surgery, Pusan National University Hospital from January 1986 to February 1992. The follow-up ranged from 24 months to 92 months, the average being 53 months. The results were as follows; 1. At the last follow-up, a radiolucent line was found in 20 cases(16.1%), but the width was less than one millimeter. Among the 20 cases, the continuous radiolucent line was found in two cases(1.6%), the progressive radiolucent line in five cases(4.0%). 2. Areas of non-contact(initial gap) between the porous mesh of the acetabular component and the bone were seen on the immediate postoperative radiographs of 35 cases(28.2%) among 124 cases. A radiolucent line developed around 13 cases(34.2%) of the 35 cases that were associated with an initial gap, but a radiolucent line developed around only seven cases(7.8%) of the 89 cases(71.8%) not associated with such a gap. 3. At the last follow-up, a vertical migration was found in five cases(4.0%), an angulation change of the acetabular cup in two cases(1.6%), but a horizontal migration of the acetabular cup was not found. 4. There was no evidence of the disruption of the titanium porous mesh of the acetabular component, and loosening, bending or breakage of the screw for fixation of the acetabular cup. And there was no revision for acetabular loosening. In conclusion, because overall loosening rate was less than 5%, the results were very satisfactory. Considering an initial gap is a important factor of acetabular loosening, we think that it is important to make less initial gap during operation.

The tibial plateau fracture involving the articular surface clinically is a very important injury which often can cause disabilities of the knee joint. Open reduction and internal fixation have been proposed as the optimal treatment of patient with Schatzker's type VI tibial plateau fracture because of the decrease in the functional impairment of the knee joint by allowing early motion. But the injury to the soft tissue is usually severe, which may lead to wound complications after internal fixation. Also delayed union, nonunion, and infection after such operation is not a few. Recently some authors have studied about the external fixation or minimal internal fixation as the treatment for tibial plateau fracture. The purpose of the current study was to compare the results of two different operative methods. The authors analyzed 9 cases of Schatzker's type VI tibial plateau fracture surgically treated at the Pusan National University Hospital from March 1991 to August 1994. The follow-up period ranged from 1 year to 4 year 7 months. The results were obtained as follows. 1. Of the 9 cases, 7 were male and 2 were female, the major population were the 6th and 7th decades. 2. The most common cause of this injury was traffic accident in 7 cases(78%). 3. About the fracture pattern, the most commom type was intercondylar fracture type in 5 cases(56%), the next one lateral condyle fracture type in 4 cases (44%). 4. Common associated injuries were ipsilateral fibula fracture in 8 cases(89%) and ipsilateral femur fracture in 4 cases(44%). 5. Six cases were treated by open reduction and internal fixation, and 3 cases were treated by external fixator. 6. According to Poster's criteria, the results were “Acceptable” in 7 cases(89%), “Unacceptable” in 2 cases(11%).

BACKGROUND AND OBJECTIVE: The outcome of asthma treatment has traditionally been assessed by measuring the conventional clinical parameters such as symptoms, expiratory flow rates and needs for medications. But none of them tells us whether the patients are actually able to function properly in their lives. Only assessment of the quality of life (QOL) can reflect the parts of patients lives affected by the disease. However, there is no measure to assess the quality of life of patients with any chronic diseases in Korea yet. We developed the QOL Questionnaire for Korean Asthmatics and evaluated its measurement properties. METHOD: The questionnaire was composed of 18 items in four domains : i.e. activity limitation (6 items), symptoms (5 items), emotional function (3 items) and environmental stimuli (4 items). At our out-patient clinic, 32 adults with moderate to severe persistent bronchial asthma were enrolled. The study design consisted of 4 week unblinded single cohort with visits at 0 and 4 weeks, and the patients were asked to answer the questionnaire by self administration method at the two separate visits. Forced expiratory volume for 1 second (FEV1) and peak expiratory flow rate (PEFR) were recorded at each visit. According to the patients and physicians global assessment, the patients were divided into two groups, i.e. stable and changed (improved). The responsiveness, reproducibility and validity of the questionnaire were evaluated. RESULTS: The total QOL scores at the second visit in the changed group were significantly higher than those at the first visit. The score differences between the two visits in the changed group were higher than in the stable group. In the stable group, the responses to the questionnaire were reproducible. The QOL scores showed good longitudinal correlation with the expiratory flow rates, whereas FEV1 did not correlate with the QOL in cross-sectional analysis. CONCLUSION: The questionnaire proved to be reproducible, responsive and valid in the subjects. It could be recommended for the outcome evaluation of Korean asthmatics.

BACKGROUND: Superior migration of humeral head has been conventionally determined by measuring the acromiohumeral distance (AHD), We sought to devise a novel measurement system more reliably and accurately than AHD. We described a structural landmark called 'C-line'. In this study, we investigated the clinical usefulness of 'step-off of the C-line (SOC)' compared to that of AHD. METHODS: The C-line formed from the medial margin of the proximal humeral head continuing up to the inferior margin of the articular glenoid and then to the lateral border of the scapula. The superior migration of the humeral head triggered by a rotator cuff tear introduces a discontinuity in this C-line. We measured the distance of this discontinuity. We enrolled 144 patients who underwent a rotator cuff repair. We selected 58 controls who didn't have any cuff lesions apparent on magnetic resonance imaging. Using radiographs derived from standardized true anteroposterior views of the shoulder, we measured the SOC and the AHD. We used t-tests for statistical analyses. RESULTS: A rotator cuff tear was associated with an increase in SOC and a decrease in AHD. In control group, the mean SOC was 1.29 ± 1.71 mm and AHD was 9.71 ± 2.65 mm. In cuff tear group, the mean SOC was 3.15 ± 3.41 mm and AHD was 8.28 ± 1.76 mm. The mean SOCs of the patient group in relation to the mean SOC of the control group according to tear size, the SOCs of medium tear and lager groups showed statistically significant increase (p<0.05). CONCLUSIONS: The SOC may be a similarly effective to diagnose cuff tears of medium size and larger compared with AHD.

BACKGROUND: Oral allergy syndrome(OAS) is composed of it,ching sense and edema in oral cavity, lips, throat, pharynx, and larynx following eating some fresh fruits or vegetables. It has been known that most of patients with OAS are allergic to pollens. Common epitopes were found among pollens, fruits and vegetables. Although OAS is a common farm of food allergy in adults, this is the first epidemiologic study of OAS in Korea. MATERIAL AND METHOD: One hundred and fifty one patients who showed positive skin reaction to pollens were telephone-interviewed. Investigation of the prevalence and clinical manifestations of OAS was possible in 81 patients. RESULT: The prevalence of OAS among these patients was 34.6% (28/81). OAS was found in 24(48%) out of 50 patients sensitized to tree pollens, whereas 4(13%) of 31 grass or weed pollen-sensitized paients had OAS. Most common causative food was apple and all of 17 apple- OAS patients were sensitized to tree pollens. Peach was the second common food and 14 of 15 peach-OAS patients were sensitized to tree pollens. Besides oral symptoms, rhinitis, asthma, diarrhea, nausea, vomiting or generalized urticaria were accompanied in half of the OAS patients (14/28). Some patients showed OAS to some unique Korean foods such as dropwort, taro and Aster. CONCLUSION: OAS was very common in pollen-sensitized patients. Larger epidemiologic studies are needed to find unique Korean foods and their antigensm causing OAS.

BACKGROUND: Chronic cough is a common clinical problem to which various etiologies are attributable; postnasal drip, asthma, gastroesophageal reflux (GER) and chronic bronchitis, However, in some cases, no particular etiology can be confirmed. OBJECTIVE: This study was aimed to evaluate cough sensitivity and the clinical manifestations of patients with idiopathic chronic cough. MATERIALS AND METHODS: We recruited 70 non-smoking patients who had been coughing for more than 3 weeks without any history, symptoms or signs of rhinitis, sinusitis, typical asthma, GER or recent upper respiratory infection episodes. Nineteen healthy controls were also enrolled. Bronchial provocation tests with methacholine, capsaicin and distilled water (DW) were performed. RESULTS: Thirteen patients were positive to rnethacholine test (PC20 < 25mg/ml) and defined as cough variant asthma. The others are classified into idiopathic chronic cough. By capsaicin and DW challenge tests, idiopathic cough patients could be divided into two groups, i.e., increased cough sensitivity (ICS) and normal cough sensitivity (NCS) groups. DW- induced cough counts were negatively correlated with C7 (lowest capsaicin concentration inducing continuous 7 or more coughs) (r=-0.739, p<0.001). No difference was found in clinical features such as age, sex, atopy, or peripheral eosinophil counts between these two groups but cough counts per cough burst were significantly higher in the ICS group. CONCLUSION: The heterogeneity in cough sensitivity of idiopathic chronic cough patients may refiect different pathophysiologic mechanisms. It is unclear whether patients with NCS merely have habitual or psychogenic cough or not. These suggest that different therapentic strategies should be established on idiopathic chronic cough patients according to cough sensitivity.

Diffuse Idiopathic Skeletal Hyperostosis (DISH) is a skeletal disease characterized by ligamentous ossification of the anterolateral side of the spine. Paravertebral and ligamentous ossification appears to be an usual complication of hypoparathyroidism. Diabetes Mellitus has often been mentioned in associated with DISH. The patient was presented with back pain, stiffness and intermittent numbness of hands and feet. Spine X-ray showed extensive ligamentous ossification of the anterolateral side of the spine with normal disc space height. Sacroiliac joints are normal. Increased bone mineral density of the L-spine and femur neck was observed, as well. Hypocalcemia, hyperphophatemia and low intact parathyroid hormone level were detected. Postprandial sugar were elevated. HLA B27 was negative.
