Magnetic Resonance image(MRI) is used as the diagnostic modality for evaluation of suspected intramedullary tumors and differential diagnosis of these tumors at the spinal cord. We experienced intramedullary astrocytoma of cerviced cord with large syrinx and multiple peritumoral cysts consisted of subacute and chronic hemorrhage at the margin and within the syrinx and cysts on MRI.

Objective: To investigate the dental phenotypes and treatment modalities (TxMod) in Korean patients with Parry–Romberg syndrome (PRS) using longitudinal data. Methods: The samples consisted of 10 PRS patients, who were treated and/or followed-up at Seoul National University Dental Hospital between 1998 and 2019. Using a novel PRS severity index based on the numbers of the atrophy-involved area and asymmetry-involved item, we classified them into mild (n = 3), moderate (n = 2), and severe (n = 5). Dental phenotypes, including congenitally missing tooth (Con-Missing-Tooth), microdontia, tooth with short root (Short-Root), tooth with dilacerated root, and delayed eruption/impacted tooth, were investigated along with Tx-Mod. Results: The side of occurrence of all dental phenotypes showed 100% concordance with the side of PRS involvement. The most two common dental phenotypes were Con-MissingTooth and Short-Root (n = 29 and n = 17 in six patients). The sums of the average number of Con-Missing-Tooth and Short-Root increased from mild PRS to moderate PRS and severe PRS cases (1.0, 6.0, and 6.2). In terms of TxMod, growth observation due to mild atrophy, fixed orthodontic treatment, and grafting were used for mild PRS cases. Tx-Mod for moderate PRS cases involved growth observation for surgery due to an early age at the initial visit. For severe PRS cases, diverse Tx-Mod combinations including unilateral functional appliance, fixed orthodontic treatment, growth observation, grafting, and orthognathic surgery were used. Conclusions The novel PRS severity index may be useful to provide primary data for individualized diagnosis and treatment planning for PRS patients.

There are two pathogenic models of renovascular hypertension (RVH) originating from renal artery stenosis. We noted a case of a boy who had severe hypertension with atrophic left kidney, hypertrophic right kidney, a segmental stricture of the abdominal aorta, and total occlusion of the right renal artery. Due to the atrophic change of the contralateral, unclipped left kidney, this patient presented with various clinical manifestations related to both models of pathogenesis of RVH occurring at the same time. We conclude that this patient presented with the middle stage of the two RVH pathogenetic models, so called the 'one-clip, one and half-kidney model.'

BACKGROUND: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. METHODS: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. RESULTS: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. CONCLUSION: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and relationship with depression and social disability. METHODS: Study subjects consisted of 35 panic disorder patients diagnosed with the criteria of DSM-IV. Data were collected through Sixteen Personality Factor Questionnaire, Ehwa Diagnostic Test of Defense Mechanism, Beck Depression Inventory and Sheehan Disability Scale. Statistics employed for the analyses were Pearson correlation and independent sample t-test. RESULTS: In personality factors and defense mechanisms, there were no definitely abnormal range of scores. But, among personality factors, tension/anxiety factor scored high and unstableness/stableness, shyness/boldness and praxernia/atunia were in low range of score. In defense mechanism, somaticzation and acting-out scored high and humor, suppression, altruism, avoidance and rationalization scored low. The mean BDI score was 18.25+/-9.97. The mean score of SDS were 4.88+/-3.11 in work category and 4.57+/-2.92 in social/leasure category. Male patients were significantly correlated with guit-proneness and atuia in personality factor and passive- aggressiveness, projection, denial and show-off in defense mechanism, compared with female patients (p<0.05). The patients' age was correlated with low intelligence in persolity factor and dissociation and anticipation in defense mechanism. It was negatively correlated with show-off (p<0.05). The BDI score was correlated with low intelligence, superego, unstableness, self-conflict, high superego and atunia in personality factor and dissociation and somatization in defense mechanism (p<0.05). There was a significant relationship between BDI score and SDS work category (p<0.05). CONCLUSION: Panic disorder patients show high score of tension/anxiety factor and they frequently use neurotic defense style like somatization. The depressive symptom, which depends on symptom severity, appears to have influence on work category and to cause social disability.

OBJECTIVES: The purpose of this study was to evaluate the characteristics of personality factor and defense mechanism and to compare the difference between non-offensive and offensive types of social phobia patients. METHODS: Study subjects consisted of 28 social phobia patients diagnosed with the criteria of DSM-IV. Data were collected through Sixteen Personality Factor Questionnaire and Ehwa Diagnostic Test of Defense Mechanism. We employed was the independent sample t-test for the analysis. RESULT: Among the personality factor, the shyness/boldness factor scored lower than normal in social phobia patients. Humor drfense scored lower than normal among defense mechanisms. There was no significant correlation between non-offensive and offensive types of social phobia in personality factors and defense mechanisms. CONCLUSIONS: Social phobia patients were shier and less frequently used humor defense than the ordinary people. There was no significant correlation between non-offensive and offensive types of social phobia patients in personality factors and defense mechanisms.

The present study investigated the urinary tract toxicity of melamine alone or in combination with cyanuric acid in rats. Male rats were orally administered melamine alone (800 mg/kg) or melamine plus cyanuric acid (50 mg/kg each) for 3 consecutive days. Although melamine treatment did not show any significant difference in body weight, kidney or urinary bladder weight, serum blood urea nitrogen (BUN) or creatinine levels, it caused a decrease in urinary pH and mild histopathological alterations in the kidney and urinary bladder. In contrast, co-administration of melamine and cyanuric acid induced a decrease in body weight, an increase in kidneys and urinary bladder weights, and an elevation in serum BUN and creatinine levels, which were not observed in animals treated with melamine alone. Histopathological examination showed that the incidence and severity of histopathological lesions in the kidney and urinary bladder were much higher than those in the melamine group. Urinalysis revealed an increase in urine occult blood, leukocytes and protein and a decrease in urinary pH. These results indicate that concomitant administration of cyanuric acid synergistically potentiated the urinary tract toxicity induced by melamine in rats. In this study, we first demonstrated the synergistic toxic effects of melamine in combination with cyanuric acid on urinary bladder and urinalysis in rats.

Neutropenic enterocolitis is a serious complication of chemotherapy for malignancies such as acute leukemia or lymphoma. The acute inflammatory disease may involve the terminal ileum, cecum and ascending colon. Although conservative care is recommended as the primary treatment modality, surgical intervention is essential for intestinal perforations, abscesses, or bleeding. We experienced a case of neutropenic enterocolitis with a liver abscess in a young leukemia patient. A 13-year-old boy with acute myelogenous leukemia had completed two cycles of chemotherapy (Arabinoside 300 mg, Dactinomycin 40 mg, VP-16 150 mg, 6- mercaptopurin 60 mg, dexametasone 3 mg). Ten days after completing the second cycle he had abdominal pain, low abdominal tenderness and a high fever. The WBC count in the peripheral blood was 210 cell/mm3. A CT scan demonstrated wall thickening of the terminal ileum and ascending colon, as well as 5 cm, and 6 cm sized homogeneous low-density areas in both hepatic lobes. A presumptive diagnosis was neutropenic enterocolitis with a liver abscess. The patient was managed conservatively with fluid resuscitation, a bowel rest, and broad-spectrum antibiotics. Twenty-five days later his abdominal pain was abruptly aggravated. The CT scan and Chest X-ray demonstrated free air in the peritoneal cavity. An emergency laparotomy was performed under a diagnosis of peritonitis with an intestinal perforation. The laparotomy show that, there were perforations at the pylorus of the stomach, and full thickness necrosis at multiple segments of the small bowel. Primary closure of the stomach, a segmental resection and an end-to-end anastomosis of the small bowel, and ileostomy were performed. However, postoperative leakage developed at the stomach. The patient recovered with supportive management. The patient had a third chemotherapy series 3 months after surgery. Three days after completing the third cycle, the patient developed peritonitis. A pyloric re-perforation of the stomach was observed on the laparotomy. Postoperative leakage developed after the primary closure of the stomach. The patient died of sepsis 54 days later. Therefore, intensive monitoring and close collaboration between the hematologist and the surgeon is essential for patients with neutropenic enterocolitis. Postoperative complications are quite common and can be fatal in patients with neutropenic enterocolitis that develops after chemotherapy.
