Multilocular cystic renal cell carcinoma is a distinct subtype of renal cell carcinoma with its pathological characteristics and good prognosis. Multilocular renal cysts and renal cell carcinoma with cystic change are important differential diagnoses. We report a case of multilocular cystic renal cell carcinoma in a 37-year-old woman who came to the hospital because of the right renal mass. The removed right kidney showed a 6x4 cm well defined cystic mass in the lower pole. On cut section there were multiple cavities in the mass, filled with serosanguineous fluid and focal yellowish solid area. Microscopically, these cysts were lined by a single layer of flat or cuboidal cells consisted of clear cytoplasm with small central nuclei. In some portions of the tumor, the clear neoplastic cells formed sheets within the septa or walls of the cysts.

CD44, also known as the Hermes antigen, H-CAM, pgp-1 antigen, and extracellular matrix receptor ECM-III, is a widely distributed integral membrane protein that exists in a variety of forms with different molecular sizes ranging from 85kd to 160kd. A number of evidence implicates CD44 as a cell adhesion molecule with a possible role in tumor progression. To evaluate the possible roles of CD44 in the metastatic process of gastric carcinoma to the regional lymph nodes, we applicated immunohistochemical stains with the CD44H and CD44v6 primary antibodies onto the 2 groups of gastric adenocarcinomas. Each group was comprised of 22 primary tumors extending to the subserosa, and one group showed nodal metastasis, while the other group did not. Seventeen primary tumors (77%) out of the 22 cases with the nodal metastasis demonstrated positivity to the CD44v6, while only 9 primary tumors (41%) out of the 22 cases without nodal metastasis did. However CD44H immunoreactivity was demonstrated in tumor cells of all cases (100%) of both groups as well as in the normal cell components. These results suggest that CD44H form is not related to the metastasis to the regional lymph nodes of gastric carcinoma. However, the expression of CD44v6 seems to play a certain role in the metastatic process of the gastric carcinoma.

Hepatic actinomycosis is a rare condition, accounting for 15% and 5% of all abdominal and actinomycosis cases, respectively. Here, we describe a case of hepatic actinomycosis accompanied by immunoglobulin G4-related inflammatory pseudotumors. To the best of our knowledge, only two such cases have been reported to date. Here, we present the case of a 72-year-old male patient. Computed tomography and magnetic resonance imaging revealed a hepatic lesion that did not follow anatomical boundaries. The lesion showed arterial phase peripheral hyperenhancement, progressive enhancement of the central portion, sharply demarcated margins, and a radial stripe pattern. The final diagnosis for this hepatic lesion was hepatic actinomycosis accompanied by immunoglobulin G4-related inflammatory pseudotumor.

The syndrome of postural headache associated with low CSF pressure usually occurs after a dural puncture, myelography, or spinal anesthesia. However, it can also develop spontaneously or after minor trauma. Although the clinical and MRI findings of this syndrome are well described, radionuclide cisterno-graphic findings have not yet been clearly characterized. We report four patients presenting with postural headache associated with very low or unmeasurable CSF pressure. Three patients developed after minor trauma, while one developed spontaneously. Brain MRI revealed symmetric pachymeningeal enhancement in all four patients. Radionuclide cisternography demonstrated delayed migration of tracer to the cerebral convexity at 6 and 24 hours in three patients, and early soft tissue uptake suggestive of CSF leakage in one. We suggest that these radionuclide cisternographic findings are supportive evidences for the presence of intracranial hypotension and may provide useful information for appropriate treatment.

Juvenile granulosa cell tumor (JGCT) is one of the sex cord stromal tumors of the ovary ocurring in the first two decades of life. These tumors are different from adult granulosa cell tumor (AJCT) with regard to clinical and pathological fetures. Follicles are often irregular, Call-exner bodies are rare, and luteinization is frequent. The tumor may be solid, cystic, or both. The most common presenting symptoms are abnormal uterine bleeding and pain. Breast swelling, pain and tenderness may also be associated with unopposed estrogen secretion by granulosa cell tumors. The tumor should be removed as soon as the diagnosis is estabilished. The juvenile granulosa cell tumor has a good overall prognosis because fewer than 5% of these tumors in children are malignant.

Enteric duplications are uncommon congenital anomalies. Duplications of the stomach account for only 3.8% of gastrointestinal duplication. More particularly, duplications involving the pylorus are extremely rare. These are characterized by firm attachment to at least one point of the alimentary tract with a well developed coat of smooth muscle and mucous membrane. The most frequent presentation is an abdominal mass with vomiting, mainly discovered during the first year of life. We experienced a 24-day-old boy with non-bilous, non-projectile vomiting and palpable abdominal mass, clinically similar to hypertrophic pyloric stenosis. He was diagnosed as having gastropyloric duplication cyst by abdominal ultrasonography, upper gastrointestinal series and abdominal computerized tomography. Thus we report a newborn infant with gastric outlet obstruction secondary to a duplication of the pylorus which is a rare cause of gastric obstruction.

Angiocentric glioma was recently recognized as a distinct clinicopathological entity in the 2007 World Health Organization classification of tumors of the central nervous system. Typically, it presents with seizure in children and young adults. However, our patient did not have a history of seizure. Seizure did not occur up to 6 months after operation. Although it usually does not have calcification brain magnetic resonance imaging in our patient showed T1-hyperintense and T2-hypointense signals with calcification.

Purpose: Incontinence-associated dermatitis (IAD) is widespread and a common problem in healthcare settings, It is defined as irritation of the perineal skin due to contact with urine, feces, or both. It is one of the major risk factors for the development of pressure injuries are regarded as a quality indicator of nursing care.It is important to understand the knowledge and attitudes of nurses who are primarily responsible for providing appropriate nursing care that includes differentiation of IAD from other skin breakdowns, and appropriate management. Therefore, the purpose of this study was to determine the knowledge, attitudes, and performance of IAD among clinical nurses in Korea. Methods: Data about IAD knowledge, attitudes, and performance were collected from August to November 2022. 656 nurses from six hospitals participated in the study. Results: The mean scores of nurses’ knowledge, attitudes, and performance were 17.98±2.91, 76.34±7.85, and 91.53±16.18, respectively. Nurses' knowledge showed a positive correlation in both attitudes (r=0.27, p<.001) and performance (r=0.09, p=.02), and attitudes and performance (r=0.34, p<.001) also showed a positive correlation. Conclusion To improve the knowledge and performance of nurses, an educational program consisting only of incontinence-related dermatitis is needed, and case-based education and clinical skills education are needed to enhance the ability to differentiate from pressure injury.

Purpose: The purpose of this study was to understand and describe the meaning of the experience of male nurses working in Intensive Care Units (ICU). Methods: Data were collected through in-depth interviews with 8 male nurses. Data were collected from november 2019 to february 2020 and were analyzed using Colaizzi's method, a phenomenological approach. Results: 8 theme clusters, and 28 themes were identified. The 8 clusters were as follows; the feeling of burden in a busy and sensitive situation, the daily life facing life and death, female colleagues and patients who are still difficult to treat, a reliable and grateful male colleague, being proud of this role that a man can do, various experiences that improve me, constant effort to be recognized as a team member, and wavering and weighing in the career. Conclusion These results could help to expand understanding the role of male nurses working in the ICU and in other areas. In addition, the results provide basic data needed to improve mutual respect and relationships between male and female nurses. It is necessary to offer mentoring programs for male nurses to adapt to nursing field.
