1.Instability Patterns of Normal Midcarpal and Radiocarpal Joint in the Sagittal Plane.
The Journal of the Korean Orthopaedic Association 1998;33(3):528-534
The midcarpal joint has inherent instability in the sagittal plane. Several instability patterns of midcarpal joint due to ligament insufficiency have been presented. We ohserved the normal midcarpal and radiocarpal behaviors of ligament laxity in the sagittal plane to investigate the significance of dorsal and palmar stress test which has been used for evaluation of the non-dissociative carpal instahilities. We performed the dorsal and palmar displacement stress test on fifty pairs of normal wrist joints under the flouroscopic views. The midcarpal joints were subluxed, more on dorsal stress, with variable degrees. Dorsal subluxations in females and third decades were more prominent than males and fourth decades. Three types of radiocarpal instability on dorsal stress test could be observed. We think that displacement stress test in the sagittal plane should be interpreted in consideration of normal instability patterns in the evaluation of ahnormal midcarpal and radiocarpal instabilities since there are variable patterns and degrees of ligament laxity in normal wrist joints.

OBJECTIVES: To estimate the prevalence of hypertension, rates of awareness, treatment modalities, and control of hypertension, and also to identify factors in rural Korea that are related to these aspects of hypertension. METHODS: A cross-sectional survey, including blood pressure(BP) measurements and interviews, investigating the variables in the health belief model was performed from August to November, 1999 on 1,426 (79.4%) study subjects out of 1,797 registered residents over 30 years old in Ibansong-Myun, Chinju City. A second survey was performed from January to March, 2000 on 376 (80.0%) subjects out of 470 hypertensive (or suspected hypertensive) subjects found in the first survey. Two BP readings were taken in each survey using a standard mercury sphygmomanometer. Hypertension was defined as either a BP reading < 140/90 mmHg in both surveys, or as subjects on oral hypertensive medication. RESULTS: Estimated hypertension prevalence was 24.9% for men, and 30.4% for women. Rates of hypertension awareness, treatment (the regular use of oral hypertensives), and control (reduction of BP to <140/90 mmHg) were 52.5%, 34.4%, and 12.9%, respectively. The factors related to lower hypertension awareness in the logistic regression analysis were male gender, farming occupation, and higher perceived barrier to medical treatment (those for whom visiting health professionals is a burden). CONCLUSIONS: To improve the low awareness, treatment, and control of hypertension, a more active and out-reaching hypertension control program, including routine BP measurements for every visitor to primary care facilities, is needed in rural Korea.

An absence or compromise of the medial collateral ligament that occurs after primary total knee arthroplasty is a challenging reconstructive problem. Treatment usually requires unlinked-constrained total knee arthroplasty. Revision with unlinked-constrained prostheses often causes more bone loss and transmits increased stress to the bone-cement and prosthesis-cement interfaces, which can increase the risk of aseptic loosening. However, there are no treatment options other than constrained prostheses. We present a 47-year-old female who suffered from medial instability that occurred after total knee arthroplasty, which was treated successfully by a medial collateral ligament reconstruction.

The purpose of this study was to evaluate the color stability of resin cements with accelerated test. Four dual curing resin cements: Panavia-F (KURARAY), Duolink (BISCO), Variolink-II (Ivoclar Vivadent), and RelyX Unicem (3M ESPE) and 1 self curing resin cement: Resiment CE (j. l. Blosser) were used in this study. In control group, Gradia Anterior (GC) composite resin and Tescera Dentin (Bisco) indirect composite were used. Ten disk shape specimens were made from each resin cement. The specimens were subjected to an accelerated aging process in a refrigerated bath circulator at 60degrees C for 15 and 30 days. Spectrophotometric analyses were made before and after 15 days and 30 days of accelerated aging time. The color characteristics (L*, a*, b*) and the color difference (DeltaE*) of the specimens before and after immersion were measured and computed. Regardless of type of the resin cements, L* value was decreased and a* value was increased, but there were no significant difference. But b* value was increased significantly (p < 0.05). Tescera inlay showed least color change (p < 0.05), but Gradia showed notable color change after 15 days. After 30 days on accelerated aging, DeltaE* value was increased (Panavia-F < Variolink-II < Resiment CE < Duolink < Unicem) (p < 0.05), but there were no significant difference among Panavia-F, Variolink-II, and Resiment CE groups. After 30 days of accelerated aging, DeltaE* value of all resin cements were greater than 3.0 and could be perceived by the human eye.

BACKGROUND: Patients with non-Q wave myocardial infarction tend to have smaller infarcts and less degree of ventricular function impairment initially, however, uncomplicated non-Q wave infarctions are known to be as serious as Q wave myocardal infarction due to residual myocardal ischemia and higher reinfarction rate. METHODS: Inorder to compare the clinical and coronary angiographic findings of Q wave infarction with those of non-Q wave infarction. 58 partients with acute myocardial infarction were reviewed retrospectively. Patients were classified into Q wave(n=45) and non-Q wave infarction(n=13) according to electrocardiographic findings. RESULTS: 1) There were no significant differences between the two groups in risk factors of coronary artery disease such as hypertension, hypercholesterolemia, smoking and diabets mellitus. 2) The peak myocardial enzyme levels of CPK, CPK-MB were significantly higher in the Q wave MI group, and the percentage of wall motion abnormality on two-dimensional echocardiography was significantly higher in Q wave MI than in the non-Q wave MI group. 3) The number of involved vessel, degree of stenosis and collateral circulation were not different but high degree of stenosis of infarct-related artery was more frequent in Q wave MI group. 4) There were no significant differences between the two groups in the incidence of arrhythmia and in-hospital mortality. CONCLUSION: There were some differences in clinical and angiographic findings, but in-hospital mortality was not significant different between two groups. Futher prospective studies should be performed to clarify the long term prognosis.

Approximately 13–20% of infants with milk allergies concurrently exhibit beef allergies. Here, we report a 24-month-old infant who exhibited both pork and beef allergies, concurrently with a milk allergy. The infant's laboratory test results were: 3.73 ISU-E (ISAC standardized unit for IgE) for cow milk β-lactoglobulin, 23.8 ISU-E for casein, 12.8 ISU-E for cow milk Bos d 6 of serum albumin, and 4.85 ISU-E for cat Fel d 2. This case report summarizes an infant patient diagnosed with a meat allergy that was associated with cow's milk allergy, using ImmunoCAP ISAC®. Not only ImmunoCAP ISAC® but also immunocap can be used to diagnose milk allergy and meat allergy at the same time, immunocap testing for component antigen is rare. ImmunoCAP ISAC® is used to diagnose these allergies in our case study, as it has advantage that only 1ml of blood is needed to run various component antigen tests.

Mycoplasma pneumoniae is the most common bacterial strain causing atypical pneumonia in children and adolencents. Although it is known to cause mild symptoms, it can also cause severe pulmonary or extrapulmonary complications in rare cases. Necrotizing pneumonia (NP) is often reported as a complication of Streptococcus pneumoniae and is very rarely caused by M. pneumoniae. We report a case in which a 5-year-old boy was diagnosed with lobar pneumonia with symptoms that aggravated even with macrolide antibiotic treatment. Anti-mycoplasma pneumoniae Ig-M test yielded high values, and direct polymerase chain reaction results were also positive. NP caused by M. pneumoniae was confirmed on computed tomography. After treatment involving tosufloxacin and systemic steroid, the lesion decreased in size and improved gradually when followed-up for more than 1 year. The patient did not have any predisposing or risk factors for NP.

Journal of the Korean Hip Society 2008;20(3):220-224
Femoral head fracture with posterior dislocation of the hip occurs relatively infrequently. Many treatment options exist for this condition. The fracture fragments of the femoral head can be internally fixed or removed depending on the severity of fracture comminution, fragment size, and location on the weight-bearing surface of the femoral head. In Pipkin type I and II fractures, the fragments are typically located anteriorly. Hence, it is important to strongly fix the fracture fragments to the femoral head rather than to excise them, in the interest of securing a better outcome. Even if the fragments are caudal to the fovea centralis, the discarding of large portions of the femoral head that are amenable to rigid fixation is not preferred. Three femoral head fractures were treated using Acutrak screws incorporated with a self-compression mechanism. We report the results and consider ways to use Acutrak screws.
