The exercise ECG gives a valuable indirect evidence of insufficient myocardial perfusion during stress, but it has been impossible with ECG data alone to localize the site or sites of partial or complete arterial occlusion. The coronary angiography has proved to be valvuable as a technique for identifying anatomical lesions. However, arteriography alone dose not provide evaluation of the underlying myocardium. The two tests are complementary, one supplying indirect physiologic data and the other providing anatomical licalization of obstruction. The author reviewd 58 patients out of 86 patients who performed treadmill test and coronary angiography at the cardiac laboratory of Yonsei University Severance Hospital from January, 1981 through December, 1983. The following results were obtained. 1) Among the 58 patients in this study, 33 had negative exercise test and 25 had positive test. 2) Among the 14 patients who ended exercise test due to chest pain,2patients had negative exercise test. Coronary angiography on all the 14 patients showed significalt coronary artery stenosis. 3) With this multigraded treadmill test, the sensitivity was 68.8% and spedccificity was 88.7%. 4) The appreance of ischemic change during the early stage of exercise, the deeper ST segment depression and the downsloping ST segment have the higest specificity as indicators of coronary artery disease. 5) Four patients showed ST segment elevation in the exercise ECG, and their coronary angiogram showed 1-vessel disease in 1 patientts, 2-vessel dosease in 2 and 3-vessel disease in 3. All of them had multiple stenosis or complete obstruction of the left anterior descending artery on coronary angiogram and ventricualar dyskinesia on the left ventriculogram.

Journal of the Korean Association of Oral and Maxillofacial Surgeons 2019;45(6):351-356
Maxillary sinus floor augmentation (MSFA) is an essential procedure for implant installation in the posterior maxillary area with vertical alveolar bone deficiency. For the past several decades, MSFA has been refined in terms of surgical methods along with technical progress, accumulation of clinical studies, and development of graft materials and surgical instruments. Although some complications in MSFA are inevitable in clinical situations, management of those complications in MSFA has been well established thanks to many clinicians and researchers. Nevertheless, some rare complications may arise and can result in fatal results. Therefore, clinicians should be well aware of such rare situations and complications associated with MSFA. In this review, the authors present several rare complications regarding MSFA, along with corresponding management strategies through a thorough review of the literature.

C1q nephropathy is an immune complex glomerulonephritis defined by the presence of mesangial C1q deposits in immunofluorescence microscopy and electron dense deposits on electron microscopy. It was described as a distinct disease entity in 1985 by Jennette and Hipp. Thirty four cases were reported in the literature but there has been no pediatric case reported in Korea yet. It commonly presents with steroid-resistent nephrotic syndrome in older children and young adults, and occasionally nephritic-nephrotic syndrome or rapidly progressive glomerulonephritis. We report a case of C1q nephropathy in a 23-month-old girl with steroid-dependent nephrotic syndrome.

BACKGROUND: Although traumatic implantation of epidermis into the dermis has been suggested as a possible mechanism of formation of palmoplantar epidermal cysts, most cases develop without a trauma history. Recently, human papillomavirus (HPV) was detected in palmoplantar epidermal cysts in some reports. OBJECTIVE: The purpose of this study was to find out the presence of HPV in palmoplantar epidermal Cysts. METHODS: Seven cases of palmoplantar epidermal cysts were studied using clinical, histopathological, and immunohistochemical examinations. They were also examined by the polymerase chain reaction (PCR) method with general primers and HPV 60 type specific primers. RESULTS: On histological examination, all three characteristic findings, that is, intracytoplasmic eosinophilic bodies in the cyst wall, parakeratosis within the cyst cavity, and the vacuolar structures, were not observed. Immnunohistochemical staining was negative for the papillomavirus common antigen. HPV DNA was not detected in these cases by PCR. CONCLUSION: We could not detect any evidence of HPV infection in our cases of palmoplantar epidermal cysts. It is suggested that either our cases could have developed through a different pathogenesis or our study was done after the disappearance of HPV.

Background:
Various types of miniplates have been developed and used for the reduction of facial bone fractures. We introduced Yang’s Keyhole (YK) plate, and reported on its short-term stability. The purpose of this study was to evaluate the long-term stability of the YK plate, as a follow-up study, by examining the patients who had used the YK plate among the patients with the reduction of mandible fractures and who visited for plate removal.
Methods:
We reviewed the medical records of 16 patients who underwent mandibular fracture fixation using a YK plate (group I) and 17 patients who underwent mandibular fracture fixation using a conventional plate (group II). Assessment was then made on malunion, occlusal stability, discomfort during the application, and clinical symptoms.
Results:
From January 2015 to December 2017, a total of 36 patients underwent mandibular fracture surgery using a YK plate. A total of 16 patients received plate removal. Among them, 15 were male and 1 female. The average age was 26 years. The applied surgical sites were the 12 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of YK plate was an average of 335 days. During the same period, 45 people underwent surgery on the conventional plate. A total of 17 patients received plate removal. Among them, 15 were male and 2 females. The average age was 36 years. The applied surgical sites were the 8 on mandibular angle, 4 on mandibular symphysis, and 2 on subcondyle. The application period of the conventional plate was an average of 349 days. No malocclusion occurred at the time of removal, and occlusion was stable. No patient complained of joint disease or discomfort.
Conclusion
The YK plate system, in which the screw was first inserted and the plate was applied, for clinical convenience did not cause any particular problem and no significant difference from the conventional plate.

PURPOSE: Suprapubic bladder aspiration(SBA) of urine is the most reliable method to obtain urine avoiding contamination in non-toilet trained infants. Ultrasonography is a useful tool for guiding the anatomic location as well as for direct visualization during procedure. We evaluated the success rate and complication of ultrasound(US) assisted SBA. METHODS: Sixty infants who visited Ewha Womans University Mokdong Hospital, with suspected urinary tract infection were randomly divided into the US assisted (n=32) and blind SBA(control, n=28) group. In US assisted SBA group, the anteroposterior(AP), transverse, and sagittal diameters and the volume of the bladder were measured. In the blind SBA group, urine was blindly aspirated when the urinary bladder was palpated at the suprapubic area. The rate of successful urine aspiration, the number of attempts until successful aspiration, aspirated urine volume were compared between the two groups. RESULTS: The success rate was 100%(32/32) in the US assisted group, which was significantly higher than 85.7%(24/28) of the control group (P<0.05). The aspirated urine volume in the US assisted group was 7.4+/-3.7 mL, which was significantly higher than 4.5+/-3.4 mL of the control group (P<0.05). The diameters and volume of bladder in successful aspiration were 2.1+/-0.7 cm in AP diameter, 3.1+/-0.6 cm in transverse diameter, 4.2+/-1.0 cm in sagittal diameter and 15.2+/-10.4 mL in volume, which were significantly higher than those (1.7+/-0.3 cm, 1.8+/-0.7 cm, 2.4+/-0.6 cm, 3.9+/-2.5) of the control group (P<0.05). The correlations between the AP(r=0.78), transverse (r=0.72), sagittal(r=0.91) diameter and bladder volume were significant (P<0.05). SBA was 100% successful in the AP diameter >3 cm, transverse diameter >4 cm, depth >4 cm and bladder volume >5 mL. CONCLUSION: US assistance can significantly improve the success rate of SBA in infant with suspected urinary tract infection.

OBJECTIVE: The Korean Medication Algorithm for the Treatment of Schizophrenia was developed by the extensive review and questionnaires. To evaluate the impact of a history of antipsychotic treatments on clinical response and algorithm application, using the data derived from the feasibility study of the Medication Algorithm for patients with schizophrenia. METHOD: Outcomes of treatment with the Medication Algorithm for 108 schizophrenics up to 4 months are presented. Measures of changes included clinical symptoms, functioning, and side effects. Comparison was done between patients with and without a history of antipsychotic treatments. RESULTS: 100 individuals (with a history=71 ; without a history=29) were analyzed for the comparison. Most of subjects without a history of antipsychotic treatments were administered on risperidone in the initial treatment. When compared with the subjects with a treatment history, the subjects without a history showed better treatment effects on clinical symptoms at the first evaluation. At 4-month, there were similar effects between the two groups except negative symptoms, in which the group with a history showed significantly more improvement than without a history. There were no significant differences in assessment of subjective opinion and well-being to drugs and quality of life, and objective evaluation of drug side effects. Among the subjects with a history, the ones starting with stage 1 showed higher positive symptoms, anxiety scores, and briefer duration of antipsychotic exposure than the ones starting with stage 2 or more advanced. CONCLUSION: This study suggests that despite some limitation, an antipsychotic treatment history may have an impact on application of medication algorithm and these data will be helpful for revision of the Medication Algorithm for the Treatment of Schizophrenia.
