Retroperitoneum is often the site of occurrence of schwannoma, but reports on schwanoma of the adrenal gland is exceptional and only 4 cases have been documented in the literature. This report is to add one such case occurred in a 53 year-old male who had anorexia, nausea and indigestion for one month. Whole body bone scan and abdominal CT scan revealed a 10 cm sized solid mass at upper pole of the left kidney. Under the impression of renal cell carcinoma, an operation was performed. The tumor was well encapsulated and appeared not to involve the kidney. The cut surfaces were light yellow and seemed to be composed of several hard lobules with areas of mucoid, cystic and calcific changes. No adrenal gland was identified grossly. But microscopically, the tumor was found to be partly surrounded by a small portion of adrenal cortical tissue. Histologically the tumor was a typical schwannoma with Verocay bodies, although modified in some extents by mucoid degeneration, cystic change, hyaline change and focal calcification. It is worthwhile to remember that the retroperitoneal schwannoma commonly had a huge size, sometimes involving the adjacent structures.

PURPOSE: The aim of this study was to evaluate whether T1-201 reinjection distinguishes viable from non-viable myocardium in patients with reverse redistribution after acute myocardial infarction. MATERIALS AND METHODS: We studied 42 patients with acute myocardial infarction (age, 55+/-12 years). Eighteen (43%) out of 42 showed reverse redistribution on dipyridamole stress-4 hour redistribution T1-201 single photon emission computed tomography (SPECT). T1-201 reinjection was performed at 24 hours. Reverse redistribution was defined as worsening of perfusion defect at 4 hour delayed scan. All patients underwent follow-up echocardiography in 4 months to assess regional wall motion improvement. T1-201 uptake on reinjection images were analyzed for the prediction of myocardial wall motion improvement. RESULTS: Of 36 segments with reverse redistribution, 17 segments showed normal wall motion on echocardiography, while 19 segments showed all motion abnormalities. Of 19 the segments with reverse redistribution, 11 (58%) showed enhanced uptake after 24 hour reinjection. Myocardial wall motion was improved in 10 of 11 segments (90%) with enhanced uptake on reinjection. Wall motion improvement was not seen in 5 of 8 segments (63%) without enhanced thallium uptake. When myocardial viability was assessed by the uptake on reinjection image, nine of 10 segments (90%) with normal or mildly decreased uptake showed improved wall motion. Wall motion was not improved in 5 of 9 segments (56%) with severely decreased uptake. CONCLUSION: In patients with acute myocardial ifarction, T1-201 reinjection imaging on myocardial segments with reverse redistribution has a high positive predictive value in the assessment of myocardial viability.

The number of Kupffer cells was evaluated in hepatocellular carcinomas, including 18 primary lesions, 3 tumor emboli within the portal vein radicles and 4 metastatic lesions and in non-neoplastic liver adjacent to the primary lesions, to persue the origin of Kupffer cells dwelling in hepatocellular carcinoma. Hepatocellular carcinomas of the sinusoidal(trabecular) type were carefully selected, and excluded were those carcinomas which showed inflammation or other changes evoking inflammation. The immunohistochemical stains for CD 68 and lysozyme were done to identify Kupffer cells and to draw the mean Kupffer cell number per high power microscopic field of each lesion. Kupffer cell was most numerous in primary lesions followed by tumor emboli and still fewer in metastatic lesions. The Kupffer cell number in the primary lesions of hepatocellular carcinoma was in turn smaller than that of the adjacent non-neoplastic liver. The results suggest that, during the early neoplastic transformation, sinusoids of the non-neoplastic liver could creep into the carcinomatous tissue accompanying Kupffer cells.

Purpose: This study aimed to understand the keywords and major topics of the educational goals and objectives of nursing educational institutions in South Korea. Methods: From May 10 to May 20, 2022, the educational goals and objectives of all 201 nursing educational institutions in South Korea were collected. Using the NetMiner program, degree and degree centrality, semantic structure, and topic modeling were analyzed. Results: The top keywords and semantic structures of educational goals included ‘respect for human (life)-spirit-science-based on, global-competency-professional nurse-nursing personnel-training, professional-science-knowledge-skills, and patients-therapeutic care-relationship.’ The educational goals’ major topics were clients well-being based on science and respect for human life, a practicing nurse with capabilities and spirit, fostering a nursing personnel with creativity and professionalism, and training of global nurses. The top keywords and semantic structures of the educational objectives included ‘holistic care-nursing-research-action-capability, critical thinking-health-problem solving-capability, and efficiency-communication-collaboration-capability.’ The educational objectives’ major topics were ‘nursing professionalism, communication and problem-solving capability; a change of healthcare environments and a progress of nursing practices; fostering professional nurses with creativity and global capability; and clients’ health and nursing practice.’ Conclusion Educational goals in nursing presented specific nursing values and concepts, such as respect for human life, therapeutic care relationships, and the promotion of well-being. Educational objectives in nursing presented the competencies of nurses as defined by the Korean Accreditation Board of Nursing Education (KABONE). Recently, the KABONE announced new program outcomes and competencies, which will require the revision of educational goals. To achieve those educational objectives, it is suggested that the expected level of competencies be clearly defined for nursing graduates.

We report a 37 year-old-female patient with papillary thyroid cancer treated by surgery who demonstrated residual thyroid and bilateral breast uptake on a diagnostic I-131 whole body scan. She had an extrathyroidal extension needing I-131 ablative therapy. Her galactorrhea was investigated and treated with low doses of bromocriptine prior to I-131 therapy. Her galactorrhea was due to the decreased secretion of PIF induced by empty sella.

To provide ideas for the recognition of neonatal and infantile liver diseases caused by cytomegalovirus(CMV) infection, histopathological examinations were made on hepatic tissues obtained by biopsy or autopsy from 23 patients. All patients were sero-positive for IgM anti CMV and had no other known or suggested etiologic factors for their liver disease. There were five different types of liver diseases: 8 cases of giant cell hepatitis(34.8%), 4 cases of biliary atresia(17.4%), 5 cases of biliary atresia with changes of neonatal hepatitis(21.7%), 4 cases of diffuse hepatic fibrosis(17.4%) and 2 cases of hepatic necrosis with CMV inclusion(8.7%). The diffuse hepatic fibrosis involved both the hepatic lobules and portal areas without evidences of regeneration. This type of liver disease appeared to be a chronic progressive illness that began during the first week of life, and in 3 of 4 cases, the liver biopsy was dong at 5 to 9 months after birth. The two patients showing CMV inclusion in their liver were premature of debilitated, and died within I month after birth. Diffuse hepatic necrosis as well as the cytomegalic change of bile duct epithelium was characteristic. The findings suggest that the pattern of CMV liver disease depends on the major site of hepatic injury, the status of status of patient's defense mechanism and the chronicity of illness.
