OBJECTIVE: To analyze the clinical characteristics of obese infertile women. MATERIAL AND METHOD: Height, weight, body mass index, menstrual pattern, glucose, insulin, glucose / insulin ratio, dehydroepiandrosterone sulfate (DHEA-S), testosterone, free testosterone and plasminogen activator inhibitor (PAI-1) of 15 obese infertile women were tested. RESULTS: Of 15 obese infertile women, the number of diabetes mellitus, hyperinsulinemia, and insulin resistance was 2 (13%), 2 (13%), 2 (13%), respectively. The incidence of increased DHEA-S, testosterone, and free testosterone was 7 (47%), 1 (7%), 6 (40%), respectively. Notably, all patients showed increased PAI-1. CONCLUSIONS: Obesity is associated with infertility as well as many kinds of health problems. Obesity is closely related to insulin resistance and it also causes hyperandrogenism. Increased PAI-1 is one of the important causes of thrombophilia. Consequently, in the workup of obese infertile patient, many aspects of health problems should be considered.

We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.

The classic clinical manifestations of acute suppurative cholangitis were first described by Charcot in 1877 as a triad of fever(and chill),jaundice and right upper quadrant pain. In 1959,Reynolds and Dargan characterized acute suppurative cholangitis as a distinct clinical entity manifested by a clinical pentad of Charcot,s three signs plus shock and central nervous system depression.We have clinical analysis of acute suppurative cholangitis,218 cases who were admitted in Chonnam Hospital from Jan.1989 to Dec.1995.All cases were treated conservatively initially,and then delayed operation was performed when the patients were improved from the septic condition by cholangitis.

CD44 is a hyaluronic acid receptor that exists as a standard 90-kd form (CD44H) as well as several CD44 variants isoforms are produced through alternative splicing. Alternatively spliced variants of the CD44 molecule have been found to be associated with invasive and metastatic potential of cancer cells and poor prognosis in several types of carcinoma. The purpose of the present study is to define the expression of CD44H and CD44v6 in ovarian tumors and to investigate whether the expression of these molecules is associated with adverse prognosis. We evaluated the expression of CD44 isoforms in 58 ovarian tumors by means of immunohistochemistry, and correlated between CD44 expression and the histologic types, tumor grade, peritoneal implants, pseudomyxoma peritonei and FIGO stage. While the CD44H was commonly expressed in ovarian tumors, the CD44v6 was expressed in a minor proportion of serous tumors in comparison with frequent expression of v6 isoform in mucinous tumors. The CD44H expression was significantly higher in stage I/II than in stage III. However, there was no correlation between the expression of CD44 and the presence of peritoneal implants or pseudomyxoma peritonei. These results suggest that CD44H could play an important role in the adhesive function in the lower stage of the ovarian tumor and reduced expression in the higher stage might be related to the metastasis and widespread invasion of ovarian carcinoma cells.

Purpose: To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea. Methods: Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment. Results: After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients. Conclusions AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.

Purpose: We evaluated the clinical manifestations of, and risk factors for, infectious keratitis in patients with ocular graft-versus-host disease (GVHD). Methods: A total of 11 patients who developed infectious keratitis after a diagnosis of ocular GVHD between January 2015 and December 2020, and 36 who did not (the control group), were included in this retrospective study. We recorded sex, age, any underlying disease, any other organ affected by systemic GVHD, systemic immunosuppressant use, follow-up duration, clinical manifestations, the severity of ocular GVHD prior to infection, the size of the epithelial defect, the depth of infiltration, hypopyon status, and the results of microbiological tests. Systemic and ocular indices (including systemic GVHD status) were compared using the chi-squared test. Risk factors for infection were identified. Results: Of the corneal indices, the presence of corneal filaments, the extent of corneal neovascularization, and the number of corneal epithelial defects were significantly higher in the infected group (p = 0.023, p = 0.004, and p = 0.001, respectively). GVHD severity was also significantly higher in that group (p < 0.001). The presence of corneal filaments, corneal neovascularization, and corneal epithelial defects prior to infection correlated significantly with the risk of infection (p = 0.046, p = 0.010, and p = 0.003, respectively). Multivariate analysis identified corneal epithelial defects as a significant risk factor for infection (p = 0.029). Conclusions In patients with ocular GVHD, corneal epithelial defects, corneal neovascularization, and corneal filaments prior to infection were associated with the development of infection. In particular, corneal epithelial defects before infection was a significant risk factor for infection.

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.
