This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

OBJECTIVE: The object of this study was to compare the diagnostic accuracy of a sonographic morphologic scoting system, the serum CA-125 assay, and a combination of both in patients undergoing laparotomy for a clinically diagnosed adnexal mass. METHODS: In 129 consecutive patients, the morphology of the mass was evaluated and scored by the morphologic scoring system of Sassones using transabdominal or transvaginal sonography and blood samples were obtained for CA-125 assay before planning surgery, RESULTS: The sensitivity of the sonographic morphologic scoring system was 90.6%, the specificity 84.5%, the positive predictive value 65.9%, and the negative predictive value 96.5%, compared with 68.8, 77.3, 50.0, and 88.2% for CA-125 and 96.9, 66.0, 48.4, and 98.5% for the two tests combined, respectively. Only one case of serous borderline ovarian tumor was missed when the two tests were combined. The sensitivity and mean value of the serum CA-125 increased with the stage of ovarian cancer. CONCLUSION: The combination of sonographic findings with a serum CA-125 assay was more sensitive, but less specific, than sonography or the serum CA-125 assay alone in predicting the malignancy of an adnexal mass. The serum CA-125 level generally reflected the stage of the disease. We think that it is reasonable to check the serum CA-125 only in cases of ovarian malignancy diagnosed by sonography.

3.Chimeric Antigen Receptor-T Cell Therapy
Korean Journal of Medicine 2022;97(4):229-237
Chimeric antigen receptor (CAR) T-cell therapy constitutes a revolutionary advancement in personalized cancer treatment. During this treatment, a patient's own T cells are genetically engineered to express a synthetic receptor that binds a tumor antigen. CAR-T cells are then expanded for clinical use and infused back into the patient's body to attack cancer. CAR-T cells have produced remarkable clinical responses with B-cell malignancies. However, CAR-T cells therapy is not without problems. Barriers to effective CAR-T cells therapy include severe life-threatening toxicities and modest anti-tumor activity. In this review, we introduce the concept of CAR-T cells therapy, currently available CAR-T cells therapy options, and how to deal with adverse events.

The purpose of this study was to evaluate the effect of stroke on hypothalamic-pituitary axis using dexamethasone suppression test. The effects were evaluated according to age, sex, type, size, and lesion site of stroke. There tests were performed in 62 patients with stroke(cerebral infarction, 42 cases : intracerebral hemorrage, 20 cases) and 21 disabled controlled patients without intracranial diseases at Yeungnam University Hospital from June 1992 to June 1993. The results summarized as follows. 1. Cerebral infarction showed significantly higher frequency of DST non-suppression in stroke patients than control (p<0.05). 2. Patients with left hemisphere stroke showed more frequent abnormal neuroendocrine test results (p<0.01). 3. Patients with large infarction revealed strongly non-suppressed DST results(p<0.01). 4. Significantly higher basal cortisol level in patients with cerebral infarction was noted(p<0.01). 5. There are no statistical significance between DST results and sex, age, motor impairment, type of cerebral infarction.

BACKGROUND: Positive end expiratory pressure (PEEP) ventilation is well established as an integral part of the management of patients with the acute lung injury. PEEP is a key element in the treatment of hypoxemia resulting from pulmonary edema. Pulmonary capillary pressure (Pcap) is the most important factor influencing lung edema formation, and an understanding of how Pcap is altered by variations of PEEP or pulmonary arterial occlusion pressure (PAOP) is important to improve the treatment of acute lung injury patients. This study was performed to evaluate the effects of PEEP on the pulmonary capillary pressure in acute lung injury patients. METHODS: This was a prospective study of 11 acute lung injury patients. The effect of PEEP on pulmonary circulation at four different levels (0,4,8, and 12cm H2O) was analyzed. Pcap was estimated visually at bed side with Swan Ganz catheters. The pulmonary vasculature was analyzed by calculating the pressure difference at the arterial and venous parts of the circulation. RESULTS: As PEEP increased from 0 to 12 cm H2O, the mean puhnonary arterial pressure (PAP) and Pcap increased respectively from 22.7 ± 7.4 to 25.3 ± 7.3 mmHg and 15.3 ± 3.3 to 17.8 ±3.2 mmHg (p<0.05). Similarly, PAOP increased from 9.8 ± 2.1 to 12.8 ± 2.1 mmHg and the central venous pressure increased from 6.1 ± 1.6 to 9.3 1: 2.3 mmHg(p<0.05). However, the pressure gradient at the arterial (PAP-Pcap) and venous (Pcap-Pcwp) part of pulmonary circulation remained unchanged at all evaluated PEEP levels. CONCLUSION: Although Pcap increasoo gradually with increased PEEP, the pressure gradient at the arterial and venous part of the pulmonary vasculature remained unchanged at all evaluated PEEP levels in acute lung injury patients.

OBJECTIVE: This study was conducted to compare the outcome of cardiopulmonary resuscitation (CPR) with AutoPulse and LUCAS in out-of-hospital cardiac arrest patients. METHODS: Between July 2017 and March 2018, a total of 152 out-of-hospital cardiac arrest patients were included for analysis. Included patients were divided into an AutoPulse group and LUCAS group. Patient's age, sex, bystander CPR, witness arrest, initial shockable rhythm, time from arrest to CPR, pre-hospital CPR duration, in-hospital CPR duration, automatic external defibrillator operation by paramedic, intubation by paramedic, intravenous line access by paramedic and target temperature management were reviewed retrospectively. In addition, blood pH, lactate level, white blood cell (WBC) count, and delta neutrophil index (DNI) were analyzed. Additionally, return of spontaneous circulation (ROSC), hospital and intensive care unit (ICU) length of stay, complications from chest compressions, and cerebral performance category (CPC) scale at discharge were analyzed. RESULTS: No differences in initial shockable rhythm, patient characteristics, management for patients and CPR duration were observed between the two groups. ROSC were significantly higher in the LUCAS group than the AutoPulse group (17.9 vs. 34.7%, P=0.025). However, hospital and ICU length of stay, CPC scale at discharge as clinical outcome and pH, lactate level, WBC count, and DNI as laboratory outcomes were not significantly different between the AutoPulse group and LUCAS group. Although the case numbers were scarce, complications from chest compressions were not significantly different between the two groups. CONCLUSION: CPR using LUCAS showed better ROSC than CPR using AutoPulse. However, hospital and ICU length of stay and CPC scale at discharge did not differ between the two groups.

PURPOSE: To describe our experience concerning clinical features, methods of treatment and outcomes of separation of the symphysis pubis during childbirth. MATERIALS AND METHODS: We experienced 26 cases during a period of 6 years from March 1992 to January 1998. Retrospectively, we analysed 23 cases which could be followed up for more than a year, each with separation of the symphysis pubis associated with childbirth. Method of treatment was pelvic sling and absolute bed rest in 18 cases of 23 cases, the others were treated with bed rest and early mobilization. RESULTS: Clinical symptoms and physical findings were similar in all cases. The duration of symptom was from 3 weeks to a year (mean=3.2 months), the size of the gap on simple X-ray ranged from 6 mm to 28 mm (mean=16 mm) initially and from 3 mm to 11 mm (mean=4.7 mm) finally. Outcomes were good in all cases with conservative treatment, although final radiologic fingings were normalized, widening, sclerosis, erosion or osteophytes. CONCLUSION: Separation of the symphysis pubis during childbirth was treated well with conservative treatments, although variable radiologic findings were noted in final X-ray finding.

Individuals at ultra-high-risk (UHR) for psychosis have become a major focus for research designed to explore markers for early detection of and clinical intervention in schizophrenia. In particular, structural magnetic resonance imaging studies in UHR individuals have provided important insight into the neurobiological basis of psychosis and have shown the brain changes associated with clinical risk factors. In this review, we describe the structural brain abnormalities in magnetic resonance images in UHR individuals. The current accumulated data demonstrate that abnormalities in the prefrontal and temporal cortex and anterior cingulate cortex occur before illness onset. These regions are compatible with the regions of structural deficits found in schizophrenia and first-episode patients. In addition, the burgeoning evidence suggests that such structural abnormalities are potential markers for the transition to psychosis. However, most findings to date are limited because they are from cross-sectional rather than longitudinal studies. Recently, researchers have emphasized neurodevelopmental considerations with respect to brain structural alterations in UHR individuals. Future studies should be conducted to characterize the differences in the brain developmental trajectory between UHR individuals and healthy controls using a longitudinal design. These new studies should contribute to early detection and management as well as provide more predictive markers of later psychosis.

BACKGROUND AND OBJECTIVES: Although several Korean PB (phonetically balanced) word lists were proposed by many investigators, there is not yet a standard PB word list established in Korea. This study aims to study the actual condition of Korean PB word lists, to investigate the frequencies of Korean phonemes and to delineate the commonly used monosyllabic words among them. MATERIALS AND METHOD: The study materials were collected from 80 training hospitals in Korea. The frequencies of the initial consonants, vowels and final consonants in the collected lists were calculated with a computer program. Common monosyllabic words were summarized in a table according to their incidences in the lists. RESULTS: Thirteen lists were used in 80 training hospitals. Hahm's list was most commonly used. Most lists showed a similar trend in the phoneme frequencies. The most common monosyllabic words were /gang/, /nun/, and /don/. CONCLUSION: These results might be valuable information for the production of a new standard Korean PB word list.
