PURPOSE: To compare the results of mitomycin C trabeculectomy and Ahmed valve implant surgery for neovascular glaucoma (NVG). METHODS: We reviewed the medical records of 58 patients (66 eyes) with NVG who had undergone mitomycin C trabeculectomy or Ahmed valve implant surgery in the previous 5 years. Trabeculectomy (A group) was performed in 27 eyes of 24 patients and valve implant surgery (B group) in 39 eyes of 34 patients. Intraocular pressure (IOP), visual acuity, complications and the rate of surgical success of the two groups were compared. IOP under 21 mmHg without medication was considered as complete success (CS), under 21 mmHg with medication as qualified success (QS), and IOP over 22 mmHg despite medication as failure (F). RESULTS: IOP at postoperative 2 months was lower in the trabeculectomy group than in the drainage implant surgery group (16.4 +/- 11.3 mmHg, 20.9 +/- 8.7 mmHg, P=.087), but at 12 months, there was no statistically significant difference (18.4 +/- 11.5 mmHg, 17.0 +/- 6.4 mmHg, P=.608). Visual acuity also showed no significant difference. The respective rate of success between A and B groups was 66.7% and 38.5% (CS), 25.9% and 33.3% (QS), and 7.4% and 28.2% (F), at postoperative 2 months, and 47.8% and 42.3% (CS), 30.4% and 46.2% (QS), and 21.7% and 11.5% (F), at 12 months. The most common postoperative complication was hyphema in both groups, while other complications were shallow anterior chamber, valve problems, etc. CONCLUSIONS: The type of surgery had no significant effect on the success rate of neovascular glaucoma treatment at postoperative 12 months.

We report a case of a 44 year old femele with unilateral aldosterone-proudcing adrenal adenoma characterized by hypertension, plasma aldosterone excess, and low plasma renin, commonly but not invariably with hypokalemia. She also had asymmetric septal hypertrophy of left ventricle established with two-dimensional echocardiography. The electrocardiogram showed inverted T wave and prominent U wave with high QRS voltage on precordial leads. In the case of this patient, we are not sure whether asymmetric septal hypertrophy was caused by secondary hypertension and chronic aldosterone excess of primary aldosteronism, or hypertrophic cardiomyopathy per se, so further long=term follow-up is required to determine it. Following the successful unilateral adrenalectomy, however, the systemic pressure fell down to the normal level and electrolyte abnormalities were corrected immediaterly within a few days and the modest regression in septal hypertrophy was noted in one year, suggesting that the promary aldosteronism contributes to the development or porgression of asymmetric septal hepertrophy.

Recently, nonsuicidal self-injury (NSSI) has been increasing considerably in school counseling. According to the Youth Counseling and Welfare Development Institute, the number of counseling support for NSSI adolescent in 2018 was more than three times higher than the previous year, and the average time when NSSI behavior first appeared was 12.43 years old. As such, adolesnect NSSI continues to increase in recent years, and the age is also gradually decreasing. Nevertheless, research on the motives and characteristics of NSSI among domestic adolescents is still insufficient. This may be attributed to the difficulty of conducting research because self-injury behavior is secretly performed. However, it is also true that this reality has another limitation in the school field, which urgently requires counseling intervention and prevention of students' mental health problems. In addition, counseling for self-injury in the school scene is the biggest cause of exhaustion for counselors because they are under very great stress to cope with repeated self-harm in the dual role of counselors and teachers in school situations. Therefore, this study examines the causes and characteristics of involuntary self-injury through previous research analysis, and examines various difficulties experienced as a school counselor, as well as the effective intervention method of non suicidal self-injury in school counseling.

Granulocytic sarcoma is a localized tumor that's composed of immature cells of the granulocytic series. The tumor may be involved anywhere in the body, but we present here a rare case that involved the gastrointestinal tract (and especially the stomach). Granulocytic sarcoma may represent the initial manifestation of blast transformation or it may herald the onset of acute leukemia from myelodysplastic syndrome. We report here on a case of gastric granulocytic sarcoma in a patient with transformed acute leukemia from myelodysplastic syndrome. A 56-year-old male who was suffering with myelodysplastic syndrome (RARS) for 5 years presented with upper abdominal pain. Gastrofiberoscopy revealed an elevated lesion with central erosion at the posterior wall of the gastric upper body, which histologically proved to be a granulocytic sarcoma. The peripheral blood smear and bone marrow examination showed acute myeloid leukemia.

There is concerns about the perceived decline in the knowledge of gross anatomy of the medical students and postgraduate trainees. It is partly caused by the introduction of integrated medical curriculum and the shortage of basic medical science program and the extension of clinical clerkship consequently. There is widespread variability in the teaching style and anatomical curricular content at the medical school in Korea. Despite these changes in the anatomical education, there have been few attempts to assess the opinions of senior clinical teachers on the state of anatomical knowledge of students and the place of anatomy teaching within the curriculum. We sought the views of the clinical teachers on the adequacy of the anatomical knowledge of current students and recent graduates of 5 medical schools in Pusan and Gyeongsang-Nam do areas. Most of the clinical teachers were of the opinion that current medical students have an insufficient anatomical knowledge. They indicated the causes of decline were the clinical irrelevant anatomical teaching content and weakness of identity of anatomy by the introduction of the integrated medical education program. There was widespread support for both the concepts of spreading anatomy teaching throughout the medical course, and an optional, clinically related final year student project in the anatomy.

PURPOSE: We evaluated the feasibility of extracting pure left ventricular blood pool and myocardial time-activity curves (TACs) and of generating factor images from human dynamic N-13 ammonia PET using factor analysis. The myocardial blood flow (MBF) estimates obtained with factor analysis were compared with those obtained with the user drawn region-of-interest (ROI) method. MATERIALS AND METHODS: Stress and rest N-13 ammonia cardiac PET imaging was acquired for 23 min in 5 patients with coronary artery disease using GE Advance tomograph. Factor analysis generated physiological TACs and factor images using the normalized TACs from each dixel. Four steps were involved in this algorithm: (a) data preprocessing; (b) principal component analysis; (c) oblique rotation with positivity constraints; (d) factor image computation. Area under curves and MBF estimated using the two compartment N-13 ammonia model were used to validate the accuracy of the factor analysis generated physiological TACs. The MBF estimated by factor analysis was compared to the values estimated by using the ROI method. RESULTS: MBF values obtained by factor analysis were linearly correlated with MBF obtained by the ROI method (slope=0.84, r=0.91). Left ventricular blood pool TACs obtained by the two methods agreed well (Area under curve ratio: 1.02 (0~1 min), 0.98 (0~2 min), 0.86 (1~2 min)). CONCLUSION:: The RESULTS of this study demonstrates that MBF can be measured accurately and noninvasively with dynamic N-13 ammonia PET imaging and factor analysis. This method is simple and accurate, and can measure MBF without blood sampling, ROI definition or spillover correction. KW: N-13 ammonia, PET, Myocardial blood flow, Factor analysis

The facial patterns were expressed by the interrelation of variable factors such as heredity, function and environment. Such variable factors have an effect on the growth and development of maxillofacial bones. The malocclusions with skeletal discrepancies are caused by abnormal forms, sizes and positions of cranial base, maxilla and mandible. For the proper diagnosis and treatment planning, the analysis of such structures is necessary. Lateral cephalograms of 54 adults with class III malocclusion patients (test group) and 61 adults with normal occlusion (control group) were analyzed. Anteroposterior relations and sizes of cranial base, maxilla, mandible were estimated to compare with those of normal ones. In test group, the anterior cranial base length was within normal range, but posterior cranial base, maxilla and mandibular body were longer than those in control group, significantly. Based on the cranial base, the location of maxilla in test group was normal, but the location of mandible was more anterior than that in control. Based on the maxilla, the location of mandible was more anterior in test group than that in control. Both mandibular body and ramus anteroposterior lengths in test group were larger than those in control. Both mandibular plane angle and upper gonial angle were within normal range, but lower gonial angle was significantly high in test group.

PURPOSE : Marrow edema and fatty degeneration of the hip joint bones could be initial and late signs inip joint and its bone diseases respectively, which might be differentiated from age-related marrow conversion pattern. So authors have investigated normal marrow conversion pattern of the femur and acetabulum around the hip joints. MATERIALS AND METHODS : Three coronal MR images of 288 hip joint bones in 144 subjects, aged 2 days to 76 years divided to 8 groups every 10 years, were retrospectively analysed for the location and appearance of the converted yellow marrow. The converted yellow marrow were divided to head, neck, and trochanter in the proximal femur and below and above 50% in acetabulum of the hip. RESULTS : The most common type of marrow conversion is the converted yellow marrow in the entire proximal femur and below 50% of acetabulum of the hip. We observed the start of marrow conversion in just before and after 2 years old and stopped at just before and after 20 years old. CONCLUSION : The understanding of age-related marrow conversion pattern of the hip joint bones would provide some information for differentiation from pathologic condition of them such as edema, fatty degeneration, metastasis, or leukemia.

PURPOSE: We assessed the correlation between ocular abnormalities and the degree of intraocular pressure (IOP) in the DBA/2J (D2) transgenic mice which were proven to have pigmentary dispersion syndrome and developing glaucoma. METHODS: Nine-months-old D2 mice were examined with biomicroscopy under anesthesia and measured for IOP by Tono-Pen, Hematoxylin and eosin staining was performed on the eye sections of the mice to analyze differences between the low-grade IOP group and the high-grade IOP group. RESULTS: Ocular abnormalities including iris pigment loss, iris transillumination, iris stromal atrophy, anterior synechia, thinning of the retina, and ganglion cell loss were found; all of which appeared to be pressure- dependent. CONCLUSIONS: These results corroborate that both IOP and age might be considered for studies using D2 mice, and suggest that D2 mice are a useful glaucoma model to study the mechanisms of retinal ganglion cell death and to evaluate strategies for neuroprotection.
