OBJECTIVE: Some vaginal procedures may be safer, easier and more successful if they could be done under direct sonographic vision of the object. METHODS: All the procedures were done under the guidance of transrectal sonography. Suction curettage, after using curved plastic Karman's cannula, additional curettage was done only when there was probable remaining conceptal tissue seen on sonography. If additional curettage was needed curved metal cannula made in the same form as plastic Karman's cannula is used first and then usual metal curette if the former did not work. A high frequency cautery unit was used for myolysis. Insertion of the flexible curved cautery tip into the myoma mass was done through the uterine cavity and coagulation of the myoma tissue was performed. Myoma biopsies were done with thin loop high frequency cautery tip through laparoscopy and the vagina. RESULTS: Suction curettage in 156 cases of early pregnancy and 2 cases of previous cesarean incision site pregnancy, D&C in 11 cases, chorionic villus sampling in 13 cases, polypectomy in 1 case, myolysis in 1 case and myoma biopsy in 2 cases were done. CONCLUSION: Performing some vaginal procedures under the guidance of transrectal sonography may be better.

Correct discrimination of the first and the second twin is important. Case: (1) The first fetus, whose amnionic cavity was closest to the cervix at 19 weeks, even though its body was higher than the second fetus, was found to be closer to the cervix by 23 gestational weeks than its twin. (2) The result of the chromosomal study of dichorionic twins at 17 gestational weeks was male with 9 inversion of the presumed first, and female with trisomy 21 of the presumed second. AT 19 gestational weeks, the sex and order of the two were found to be reversed at sonography for selective termination. In diamnionic twins, the fetus in the amnionic sac closest to the cervix is nominated as the first.

Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.

A 33-year-old-woman with twin pregnancy underwent genetic amniocentesis in our hospital at 16 weeks of gestation. Fetal chromosomal analysis showed 46,XY,inv(9) and 47,XX,+21. The affected twin was terminated by ultrasonographically guided intracardiac injection of 3 ml potassium chloride solution at 19 weeks of gestation. A healthy 2570 g male infant was born by cesarean section with Apgar scores of 8 and 9 at one and five minutes, respectively.

PURPOSE: We evaluated the surgical outcomes and complications of new pediatric intraocular lens in congenital cataract. METHODS: A retrospective study was carried out on 29 eyes of 22 patients diagnosed with congenital cataract that underwent optic capture following lens emulsification. New pediatric intraocular lens (LJC 575A, Lucid Korea, Seoul, Korea) implantation into the bag was performed with posterior capsulorrhexis and anterior vitrectomy. RESULTS: After follow-up of 17.79+/-7.08 months, 15 eyes showed a visual acuity of 0.5 or above, and 10 (71.4%) of the 14 eyes showed a visual acuity of 20/470 or above. As for complications, posterior synechia developed in 8 eyes, exudative membrane was found in 3 eyes, iris capture by IOL haptic was found in 1 eye, and slight opacification of posterior capsule was identified in 1 eye. CONCLUSIONS: Use of new 8 mm pediatric intraocular lens in congenital cataract may be considered selectively.

The purpose of this study was to determine the level of cardiopulmonary resuscitation (CPR) training among Korean older adults in a community and the factors associated with CPR training. Methods: A total of 51,939 elders were selected and analyzed using the 2022 Community Health Survey. The collected data were analysed using the Rao-Scott test and logistic regression via the SAS 9.4 program. Results: A total of 7.3% of older adults received CPR training. Factors influencing CPR training were age (odds ratio [OR]=4.76, 95% confidence interval [CI]=2.55~8.90), level of education (OR=2.43, 95% CI=1.77~3.33), region (OR=1.16, 95% CI=1.05~1.27), working (OR=3.68, 95% CI=3.33~4.07), and subjective health status (OR=1.57, 95% CI=1.37~1.79). Conclusion: Based on the results of this study, there is a need to explore various ways to improve CPR training for community older adults who are vulnerable to emergency situations.

BACKGROUND: Histological analysis of tuberculosis shows a spectrum of findings, from well formed granulmatous inflammation with few bacilli in patient with normal immune response to M. tuberculosis to poorly formed granulomatous inflammation with many bacilli in patient with defective immune response. To evaluate the degree of immune response to M. tuberculosis, we studied the histologic features, including the presence of acid fast bacilli(AFB) in lymph node of patients with cervical tuberculous lymphadenitis, and compared them with clinical characteristics. METHODS: We reviewed the histologic features of 33 cases of cervical tuberculous lymphadenitis and processed the excised nodes for auramine-rhodamine staining to detect AFB. The AFB positivity in tissue was compared with the histologic features(degree of granuloma formation, presence of caseation necrosis, presence of neutrophilic infiltration) and clinical characteristics (lymph node size, duration of symptom, presence of local symptom or radiologic evidence of pulmonary tuberculosis). RESULTS: 1) The mean age at diagnosis was 42.4 years, and male to female ratio was 1 : 45. 2) Histologically, all cases showed well formed granuloma and variable degrees of caseation necrosis, and 39% of the cases showed neutrophilic infiltration in the granulomatous inflammation. 3) AFB were confirmed in 52% of the cases, and they were found extracellularly and at the periphery of caseation necrosis. 4) There was no association between AFB Positivity and histological features or clinical characteristics. CONCLUSION: Cervical tuberculous lymphadenitis showed well formed granulomatous inflammation with caseation necrosis, and there was no association between AFB positivity in the tissue and histological or clinical characteristics.

OBJECTIVE: The purposes of this study were to compare the working memory span between mild cognitive impairment (MCI) and Alzheimer's disease (AD) in the Korean elderly population and to evaluate the effectiveness of the working memory span tests. METHODS: 32 normal controls (NC), 26 patients with MCI and 28 AD patients at a mild stage were participated in this study. We used newly devised working memory span tests (Word span test and Dot matrix) according to the components of working memory ;central executive, phonological loop, and visuospatial sketchpad. And the results were compared with the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K). To evaluate the effectiveness of the working memory tests and CERAD-K to screen MCI and AD, receiver operating characteristic curves were plotted. RESULTS: All subsets of the two working memory span tests showed significant decline in verbal and visuospatial working memory in AD. But there was no significant difference between NC and MCI. Compared to CERAD-K, the two working memory tests showed good effectiveness to discriminate AD. CONCLUSION: This study showed that working memory span tests could be effective diagnosing tools for detecting AD. But for the MCI, the working memory impairment was not prominent than episodic memory impairment. This is supposed to result from the various kinds of working memory components, especially the episodic buffer.

BCL-2 interacting cell death suppressor (BIS), which is ubiquitously expressed, has important roles in various cellular processes, such as apoptosis, the cellular stress response, migration and invasion and protein quality control. In particular, BIS is highly expressed in skeletal and cardiac muscles, and BIS gene mutations result in human myopathy. In this study, we show that mRNA and protein levels of BIS were markedly increased during skeletal myogenesis in C2C12 cells and mouse satellite cells. BIS knockdown did not prevent the early stage of skeletal myogenesis, but did induce muscle atrophy and a decrease in the diameter of myotubes. BIS knockdown significantly suppressed the expression level of myosin heavy chain (MyHC) without changing the expression levels of myogenic marker proteins, such as Mgn, Cav-3 and MG53. In addition, BIS endogenously interacted with MyHC, and BIS knockdown induced MyHC ubiquitination and degradation. From these data, we conclude that molecular association of MyHC and BIS is necessary for MyHC stabilization in skeletal muscle.
