Journal of the Korean Radiological Society 1998;38(5):875-878
Intraabdominal desmopl small round cell tumor is a rare neoplasm predominant in adolescent or young adult male. The tumor is characterized by widespread growht along the peritoneal surfaces of the abdomen and pelvis,typical histologic features, and a specific immunohistochemical staining pattern. We report the clinical,radiologic, and pathologc findings of intraabdominal desmoplastic small round cell tumor.

Chromosomally derived sterility has long been recognized. A review of the literature of somatic chromosome investigations in infertile males has shown that 13.7% of azoospermic males and 4.6% of oligozoospermic males have an abnormal karyotype. In the first group, sex chromosome abnormalities predominate (mainly 47,XXY), whereas in the latter, autosome anomalies (i.e. Robertsonian and reciprocal translocations) are the most frequent. A similar review on meiotic studies revealed that meiotic chromosome anomalies can explain male infertility in 4.3-40.4% of patients. Recently, fluorescent in-situ hybridization studies on spermatozoa from infertile men were published; it was suggested that both X-Y pairing and pairing of the autosomes were impaired, resulting in spermatogenic disruption. It is estimated that there are 2,000 genes that regulate spermatogenesis, most of these being present on the autosomes, but there are approximately 30 genes on the Y chromosome. In general, autosomal genes that regulate spermatogenesis are concerned with regulation of metabolic processes in other cells in the body as well as in the cells of spermatogenesis, whereas Y genes are not essential for vital functions related to reproduction. To be able to provide proper counseling for those couples whose male infertility can now be treated by intracytoplasmic sperm injection, it is suggested that clinical investigations should include mitotic and meiotic studies, an analysis of the chromosome content of individual spermatozoa and a DNA analysis of blood and spermatozoa to detect partially deleted Y chromosome material. We have experienced a case of azoospermia associated with inversion of chromosome 1. So we report this case with a brief review of literatures.

Pulsatile secretion of GnRH from the hypothalamus is a prerequisite for both the initiation and maintenance of the reproductive axis in humans. Failure of this episodic GnRH secretion results in the clinical syndrome of hypogonadotropic hypogonadism. Deficient GnRH secretion may occur in isolation (idiopathic hypogonadotropic hypogonadism: IHH), in association with anosmia (Kallmann syndrome), or as a result of a variety of structural and functional lesions of the hypothalamic pituitary axis. The familial occurrence of hypogonadotropic hypogonadism associated with anosmia, color blindness, synkinesia, and mental defect is the classic Kallmann syndrome. Affected individuals respond readily to pulsatile administration of exogenous GnRH, and clearly this is the most physiologic approach to ovulation induction. For women not seeking pregnancy, replacement therapy with exogenous estrogen and progestin is indicated. We have experienced a case of Kallmann syndrome which was conceived by administration of gonadotropin. So we report this case with a brief review of literatures.

A balanced translocation in a parent may produce unbalanced gametes leading to abortions or defective liveborn children, or interval infertility. It also may give rise to a balanced gamete resulting in a balanced carrier, or it may produce a cytogenetically normal gamete. The incidence of balanced chromosomal translocations in couples with multiple abortions was reported as 0% to 31%. This wide variation is related to the heterogeneous criteria used for patient selection. Because parents with balanced chromosomal rearrangements and history of only repeated abortions have a significant chance with each pregnancy of having a child with normal or balanced karyotype, the usual criteria for investigation include at least two abortions or reproductive losses. There is no evidence from several reported series that increasing the number of losses to three or more leads to any change in the yield of chromosomal rearrangements detected.

7.Pathologic Characteristics and Differential Diagnosis of Hodgkin Lymphoma.
Korean Journal of Medicine 2011;81(5):543-553
Recent advances in the understanding of the biology of Hodgkin lymphoma have led to a new classification. Hodgkin lymphoma is now recognized as a B-cell disorder of germinal center or post-germinal center origin. In the WHO classification, Hodgkin lymphoma consists of two categories, namely, nodular lymphocyte predominant Hodgkin lymphoma and classical Hodgkin lymphoma. Classical Hodgkin lymphoma encompasses not only nodular sclerosis, mixed cellularity, and lymphocyte depletion subtypes, but also lymphocyte-rich subtype, among which, nodular sclerosis stands out as a distinct entity. A borderline neoplasm with features intermediate between Hodgkin lymphoma and diffuse large B-cell lymphoma has also been recognized.

8.Analysis of the relative importance of key factors in nursing workforce management for pandemic response in general hospitals and long-term care hospitals

Journal of Korean Academy of Nursing 2025;55(2):236-248
Purpose:
This study aimed to identify the key factors in nursing workforce management for pandemic response in general hospitals and long-term care hospitals and to analyze the relative importance of these factors.
Methods:
A validity test was conducted with experts to select four categories and 30 key factors related to nursing workforce management for pandemic response. Surveys were collected from 25 nursing managers in general hospitals and 21 nursing managers in long-term care hospitals, and the relative importance of the key factors was analyzed using the analytic hierarchy process method.
Results:
Differences were found between the two groups in the relative importance of nursing workforce management for pandemic response. Specifically, the highest-ranking category was “workforce recruitment and redeployment” for general hospitals, but “workforce support and protection” for long-term care hospitals. The most important factor regarding nursing workforce management was the “nurse-to-patient ratio” for both general and long-term care hospitals.
Conclusion
General and long-term care hospitals need to establish nursing workforce management strategies to effectively respond to pandemics with appropriate consideration of the relative importance and prioritization of key factors based on hospital characteristics.
