We recently treated an infant with abnormal calcification in the soft tissues of the wrist and hand caused by an intravenous injection of calcium gluconate for treatment of neonatal hypocalcemia. The cause of the soft tissue calcifications was quite puzzling, if the incident of calcium gluconate extravasation had been overlooked, because the lesions mimicked for cellulitis or abscesses and treated as such. All radiographic evidence of calcification gradually resorbed by conservative management.

Magnetic resonance imaging(MRI) is accepted as a useful tool for the diagnosis of injury of the knee recently. The anterior cruciate ligament tear is accompanied by the damage of the osseous and soft tissue of the knee. The occult osseous lesion is found on magnetic resonance imaging as bone density change that is not found on the simple radiograph. From Jan. 1992 to Apr. 1994, magnetic resonance imaging was performed on 44 patients with acute anterior cruciate ligament tears. MRI was done within 6 weeks of the index anterior cruciate ligament injury. The criteria of decreased signal intensity on the Tl weighted image and increased signal intensity on the T2 weighted image was applied for the incidence assessment of the occult osseous lesion. After arthroscopy with or without ACL reconstruction, follow-up simple radiograph was checked every 3 months. Occult osseous lesions were documented in 32(73%) of the 44 patients. Of the 32 patients with bony lesion, 81% had lesions of the lateral compartment. Lateral femoral condyle was involved in 15 cases(46.9%), and lateral tibial plateau in 22 cases (68.8%). Follow-up X-ray revealed no joint deperession in all of the 32 patients with the occult osseous lesion. This result suggests that there is a high correlation between the occult osseous lesion of lateral compartment of the knee on magnetic resonance imaging and anterior cruciate ligament tear. The presence of the occult osseous lesion in the patient with acute anterior cruciate ligament tear did not affect rehabilitation and weight bearing.

PURPOSE: This study investigated the influence of patent ductus arteriosus (PDA) and its treatment on incidence and progression of retinopathy of prematurity (ROP). METHODS: The authors retrospectively reviewed the medical records of 408 infants who underwent screening examinations for ROP at the Neonatal Intensive Care Unit of our hospital. RESULTS: The total incidence of ROP was 23.5% (96 out of 408) and the patients that needed treatment were 7.4% (30 out of 408). The mean birth weight and gestational age was 1406.1 grams and 30.67 weeks in patients without ROP, and 979.8 grams and 27.46 weeks in patients with ROP, respectively. In both total and very low birth weight (VLBW) patients, the incidence of ROP was higher in the PDA group than the non-PDA group, but the PDA group was an independent risk factor only in the VLBW group (p = 0.033). The incidence of threshold disease was not significantly different between the PDA and control groups (p = 0.757). There was no significant difference of incidence of ROP and threshold disease among the 3 treatment groups for PDA. CONCLUSIONS: In VLBW patients, the presence of PDA increased the risk of ROP and its progression, thus more attention is needed for PDA patients. However, there was no significant difference in ROP incidence and progression according to different PDA treatment methods.

BACKGROUND/AIMS: There is uncertainty about how to measure outcomes reported by patients in gastroesophageal reflux disease (GERD). This study was conducted to develop an instrument and to determine of the definition of respondent for a patient reported outcomes to assess the efficacy of a treatment used for GERD treatment. METHODS: A structural process has developed a self-evaluation questionnaire for GERD (SEQ-GERD); health-related quality of life questionnaire for GERD (GERD-QOL) was translated through cross-cultural validation. Two-week reproducibility was evaluated and construct validity was assessed by correlating the SEQ-GERD with the Patient Assessment of Gastrointestinal Disorders (PAGI-SYM), the reflux disease questionnaire (RDQ), and GERD-QOL. Changes in SEQ-GERD scores were compared to assess the discriminative validity following 4 weeks of proton pump inhibitor administration. RESULTS: A total of 83 Korean patients were included (mean age 46 ± 14 years, females 61.4%). The internal consistency of the 19-item SEQ-GERD was good (alpha = 0.60–0.94) and the test–retest reliability was high (intra-class correlation coefficient = 0.67–0.95). The SEQ-GERD highly correlated with the GERD domain of the PAGI-SYM (correlation coefficient r = 0.894, P < 0.001), the RDQ-GERD (r = 0.877, P < 0.001), and GERD-QOL (r =−0.536, P < 0.05). SEQ-GERD scores significantly varied according to the overall treatment effectiveness scale of drug responsiveness and significantly decreased after drug treatment (mean differences according to the overall treatment effectiveness scale, P = 0.020). CONCLUSION: This study supports that SEQ-GERD is reliable and valid, and can be used to evaluate the treatment response in patients with GERD.

Diagnosing pseudoaneurysms of the popliteal artery is usually straightforward in physical examinations and imaging findings. However, when a pseudoaneurysm shows a soft tissue mass with adjacent osseous change, it can mimic a bone tumor or a soft tissue sarcoma. We present a case of a 65-year-old man who had a pseudoaneurysm of the popliteal artery showing soft tissue mass and insinuating into the intramedullary cavity of the tibia. This presented case emphasizes the importance of considering pseudoaneurysms in the differential diagnosis of an apparent soft tissue mass with pressure erosion in adjacent bone.

We evaluated the usefulness of preoperative computed tomography (CT) in 26 patients with transitional cell carcinoma (TCC) of the renal pelvis or ureter. Also we had comparative analysis between CT and conventional urography in diagnosis. The conventional imaging methods such as excretory urography and retrograde pyelography are helpful in localizing the lesions but usually cannot detect extension into the peripelvic and/or periureteral fat or metastasis to the lymph nodes. Of 17 patients who were thought localized by CT, 16 were localized in the mucosa or muscle layer and 1 was invasive to periureteral or peripelvic tissue pathologically. Of 8 patients who were thought invasive to periureteral or peripelvic tissue by CT, 5 were identical and 3 were metastatic to lymph nodes pathologically In conclusion, preoperative CT is thought to be useful tool for the diagnosis and staging in TCC of the pelvis or ureter and the sensitivity and specificity of CT were higher in localized diseases than in advanced diseases.

BACKGROUND: Recent technological developments have introduced a new method to identifying M. tuberculosis complex DNA in clinical samples directly. The direct amplification test (DAT) is approved for identifying M. tuberculosis complex in respiratory specimens that are smear-positive for acid-fast bacilli (AFB). When there is a discrepancy between the AFB smear and DAT, no information on their clinical utility is currently available. In this study, the diagnostic reliability of DAT was investigated in suspected pulmonary tuberculosis patients whose sputum AFB smear was negative. METHODS: From June 1, 1998 through May 30, 1999, 909 patients with presumed active pulmonary tuberculosis were enrolled. A sputum AFB stain, culture, DAT and /or biopsy were performed. using the criteria of clinical tuberculosis or confirmed tuberculosis, the positive predictive value of DAT in diagnosing pulmonary tuberculosis was investigated. RESULTS: The positive predictive value of DAT was 82.1% by the clinically active tuberculosis criteria. However, it decreased to 61.5% when diagnosis was restricted to only to culture positive or biopsy proven cases. The false positive rate of DAT was 18.0%. CONCLUSION: The DAT is a valuable diagnostic method in suspected patients whose sputum AFB is was negative.

The Objective of this research was to construct the multimedia database system that was necessary for the education of the practitioners and the students. To establish this system, there were technical problems as follows: 1) The processing of the images, 2) The rapid processing of the information with the computer network, 3) The development of diagnosis tools, 4) The technique to establish the database system, 5)The link between the database system and the internet, and 6) The method to educate through many cases. The analysis for diagnosis and treatment planning were provided as two parts : model analysis and cephalometric analysis. As a model analysis, arch length discrepancy and Bolton tooth ratio were provided for the part of patient information. Cephalometric analyses were provided in the part of initial diagnosis. The Cephalometric analysis ver 2.0 and the PowerCeph pro 3.3.5 were used to show Tweed, Steiner and Jarabak analysis. In the main part, Kim's analysis and some measurements were added. In the post-treatment or retention part, we show the superimposition of the cephalometrics with which you can find the effectiveness of the various orthodontic treatment.
