Background: Since the global coronavirus disease 2019 (COVID-19) pandemic, nonpharmacological interventions (NPIs) such as extensive and comprehensive hand hygiene, mask-wearing, and social distancing have been implemented globally. This study aimed to investigate changes in respiratory viruses other than severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) that occurred following the implementation of these NPIs. Methods: From January 2018 to December 2021, influenza-like illness patient specimens and specimens from the Korea Influenza and Respiratory Viruses Surveillance System were analyzed at the Incheon Metropolitan City Institute of Public Health and Environment.Oropharyngeal or nasopharyngeal swab samples from respiratory infection patients were transferred in a virus transport medium at 4°C. After RNA or DNA extraction, respiratory virus-specific genes for human influenza virus (IFV), adenovirus (ADV), parainfluenza virus (PIV), respiratory syncytial virus (RSV), human rhinovirus (hRV), human coronavirus, human bocavirus, and human metapneumovirus were detected by individual real-time reverse transcription polymerase chain reaction. Results: A total 3,334 samples were collected. After NPI was implemented, the detection of respiratory viruses other than SARS-CoV-2 decreased overall. The yearly detection rate of respiratory viruses was decreased from 69.5% (399/574) in 2018 and 73.3% (505/689) in 2019 to 19.8% (206/1,043) in 2020 and 34.9% (365/1,028) in 2021. The epidemic was more prominent in respiratory viruses such as IFV and RSV, which were considered dominant viruses, especially those with viral envelopes. Among viruses that were not considered dominant, hRV showed no clear change before and after NPI, while PIV showed a rapid increase compared to the existing dominant viruses between October–December 2021, after the increase in the number of gatherings started at the end of September and the “Relaxing COVID19 and mitigation policy,” which was implemented on November 1. Conclusion NPI seems to have influenced the isolation and transmission of respiratory viruses in South Korea. In the future, additional studies focusing on the isolation and transmission patterns of respiratory viruses following NPI are needed.

OBJECTIVE: Nitric oxide has a short half-life and is easily oxidized by nitrite, we can indirectly find out its activity by measuring the nitric oxide synthase in cells. The purpose of this study is to confirm the differences in the expression modes of eNOS in uterine endometrium and myometrium between the patients of uterine leiomyoma and the control group. METHODS: We defined the patient group as perimenopausal women who were diagnosed with uterine leiomyoma and underwent total hysterectomy, and the control group as the women who had no lesions in uterus. All of them were classified into proliferative phase and secretory phase by the Noyes standards and compared by immunohistochemical stain for eNOS. RESULTS: There is no significant differences between the patients of uterine leiomyoma and the control group statistically (endometrium P=0.319, myometrium P=0.264). The expression of eNOS in the vascular endothelial cells of the endometrium did not show significant differences statistically by menstrual cycle (proliferative phage P=0.549, secretory phage P=0.240). The expression of eNOS in the myometrium also did not show significant differences by menstrual cycle or by group statistically (proliferative phage P=0.279, secretory phage P=0.224). CONCLUSIONS: In this study, the expression of endothelial nitric oxide synthase was higher in the patients of uterine leiomyoma than in the control group, and during the secretory phase in menstrual period, but there was no statistical significance. We suppose that we can get statistically significant results if we have many cases of subjects.

OBJECTIVE: The aim of our study is to evaluate the effect of uterine artery embolization as primary treatment for symptomatic uterine fibroid METHODS: From December 1999 to December 2004, 25 patients underwent uterine artery embolization for the treatment of uterine fibroid. The patients were followed up at regular intervals (at 1st, 3rd, 6th month and annual) for 3 years. The mean duration of follow-up was about 41 month (range; 41+/-15). During follow-up period, consecutive uterine and fibroid volume, and symptoms were checked. RESULTS: The uterine volumes were significantly reduced by 27% (P=0.0238) after 3month. And the fibroid volumes were significantly reduced by 59% (P=0.0070) after 1month. The uterine volumes were significantly reduced by 27% (P=0.0082) after 3 years. And the fibroid volumes were significantly reduced by 60% (P=0.0445) after 3 years. All women reported noticeable improvement of menorrhagia after complete of follow up. But, two of nine women who had symptoms of dysmenorrhea or lower abdominal pain, showed no changes in symptoms CONCLUSION: Uterine artery embolization appears to be effective in controlling symptoms, and substantially reducing uterine and fibroid volume with few complication after 3 years. However, long term follow-up will be necessary to establish the efficacy of this procedure.

Actinomyces species are gram-positive, non-acid fast anaerobic bacteria that exhibit branching, filamentous growth. More recently, It reported that female genital actinomycosis has been associated with the use of an intrauterine contraceptive device (IUD). We have experienced a case of pelvic and abdominal wall actinomycosis with mucinous cystadenoma in a 36-years-old woman using IUD and report it with brief review of literature.

OBJECTIVE: To evaluate the clinicopathological characteristics of mucinous borderline tumor associated with mature cystic teratoma and the origin of its cell type. METHODS: Five patients who were diagnosed as mucinous borderline tumor associated with mature cystic teratoma and treated in Samsung Cheil Hospital from January 1996 to September 2004 were analyzed. In addition MEDLINE, other data bases in English as well as in Korean revealed two more cases. We analyzed the result with patient's characteristics, preoperative symptoms, mass sizes, serum CA-125, operative procedure, stages, recurrence and survival period. Histological slides of the specimens were analysed for expression of cytokeratin (CK)-7 and cytokeratin (CK)-20 by immunohistochemical staining to know the origin of the cell. RESULTS: The mean age was 45 years (25-61 years). Preoperative symptoms were palpable abdominal mass, abdominal pain and urinary frequency. The mean level of CA-125 was 46.05 U/mL and the mean tumor size was 16.75 cm (8.8-22.0 cm). Post surgical FIGO staging was; stage Ia in 6 cases, stage Ic in 1 case. Four cases were CK7(-)/CK20(+), reflecting gastrointestinal origin, and also showed pattern of pseudomyxoma peritoneii. Mean survival period was 32.7 months (6-67 months) without evidence of recurrence, except one case. CONCLUSION: Our findings suggest that mucinous borderline tumor associated with mature cystic teratoma, is diagnosed at relatively young age and early stage, associated with good prognosis.

Multiple gestation accounts for 1 percent of all pregnancies. But, the morbidity of congenital anomaly is more than 2 times in contrast to singleton gestation. The major congenital anomaly was developed about 2 percent in the multiple gestation. Hydrocephalus and anencephaly, known central nervous system anomaly, were seen about 0.1% each other in singleton gestation. We have experienced a case of prenatally detected concomitant hydrocephalus and anencephaly in twin pregnancy which was diagnosed by ultrasonography at 16 weeks gestation. Thus, we report a case with brief review of the literature.

OBJECTIVE: The purpose of this prospective study was to determine the feasibility of sentinel lymph node (SN) identification and to evaluate the factors that influence the sentinel node detection rate in patients with cervical cancer of the uterus. METHODS: Forty three patients underwent intracervical injection of 1% isosulfan blue dye at the time of planned radical hysterectomy and lymphadenectomy between January 2003 and July 2003. With visual detection of blue nodes, SNs were identified and separately removed. And then all patients underwent complete pelvic lymph nodes dissection and/or para-aortic lymph nodes dissection. If frozen sections of the lymph nodes were negative, radical hysterectomy was performed. Tumor characteristics, surgical findings, specific locations of SN and final pathologic results were recorded and correlated with final pathologic results. RESULTS: The mean age of patients was 49.3 years (30-78). SNs were identified in 23 of 43 (53%) patients. About 48.7% of SNs were found in the external iliac region, 31.7% in the obturator region, 17.0% in the internal iliac region and 2.4% in the common iliac region. Metastatic nodes were detected in 11 of 43 (26%) patients. Among 23 patients whose SNs were detected, 5 patients had metastatic nodes while among 20 patients whose SNs were not detected, 8 patients had metastatic nodes. No false negative SN results were obtained. Successful SN detection was more likely performed in patients with preoperative conization (P=0.0156). However, age, stage, histologic type, operation type, and neoadjuvant chemotherapy did not show any significant differences in SN detection rate. CONCLUSION: The identification of the SN with isosulfan blue dye is feasible and safe. SN detection rate was high in patients with preoperative conization. But low detection rate should be further investigated.

The objective of this study is to describe the clinical outcomes of patients treated for cervical pregnancy with or without methotrexate (MTX) and to evaluate the effects of MTX in the treatment of cervical pregnancy. Between January 1993 and February 2000, 31 patients were diagnosed with cervical pregnancy. Twenty-two patients were treated with MTX chemotherapy and nine patients were treated with surgical procedures without MTX treatment. In the non-MTX treatment group, three patients underwent total abdominal hysterectomy, five required adjuvant procedures to control the bleeding during dilatation and curettage (D&C) and only one patient was treated with a simple D&C. In the MTX treatment group, fourteen (63.6%) patients were treated with only MTX and eight (36.4%) cases underwent concomitant procedures (simple curettage, curettage and Foley catheter tamponade, cer-vical cerclage, ligation of the descending branches of uterine arteries, or ligation of hypogastric arteries). The uterus was preserved in all cases and three women delivered healthy babies in their subsequent pregnancy. In conclusion, early diagnosis, appropriate MTX regimen in combination of necessary adjuvant conservative procedures could contribute to successful treatment with preservation of the uterus and future reproductive ability.

The purposes of this study were to investigate the current status of contracted hospital food services and to find out the difference in accordance with the number of beds in hospitals. Thirty six hospitals having more than 100beds in Seoul, Inchon and Kyungkido were the subjects of this study. Data was collected through surveys. The survey was conducted during March and April in 2002. The Questionnaires were mailed to the 36 directors of dietetic departments of the hospitals and 36 managers of contracting patient food services. Statistical analysis was completed using SPSS Win(11.0) for descriptive analysis and t-test. The results of the study are summerized as follows; I. Hospital perspective : The range covered by contract food service was 63.3% and 36.7% in hospital food services, and medical nutrition services. The patient and employee food services were in 83.3%, and patient food services were in 6.7%. The methods selecting contractors are general, limited, selected and competitive biddings, and private contracts. The responsibility for supervision of contract food services was the dietetic department (51.7%) in most cases. Hospitals having personnel responsible for contracting affairs were in 75.9% of the cases and 24.1% did not have personnel. The biggest reason for contracting was facilitation of personnel management. The most important criteria on selecting food services contractors was the professionality of the contractor. II. Contractor's perspective : The cost per meal in the year 2001 was composed of 1,905 won for food cost, 1,081 won for labor cost, 222 won for expenses, 114 won for VAT, 14 won for rent and 146 won for miscellaneous or controllable expense, representing 109 won loss per meal. The profit-and-loss contract cost is higher than the fee-contract cost. The ratios of food cost, labor cost and expenses are higher and the ratios of miscellaneous or controllable expense, VAT, rent and profit are lower in hospitals with more than 400 beds compared with those less than 400 beds. However, no significant differences are present between these two groups of hospitals. The actual contract period was 2.2 years upon initial contract and 1.2 years upon renewal. The initial investment cost was 53 million won and the cost of renovation and repair was 8.5 million won. Significant differences were present between two groups of hospitals. The conditions of employment and number of personnel hired by contractors for contract patient food services were significantly different according to the number of beds.
