1.Incidence of the chlamydial conjunctivitis in the newborn period.
Yeungnam University Journal of Medicine 1989;6(2):23-28
After application of silver nitrate on every newborn, the incidence of gonococcal conjunctivitis was markedly decreased. But recently neonatal conjunctivitis due to chlamydial infection is increasing, so clinical observation was made on 26 newborn infants who showed eye discharge from June 1st to August 31st 1989. The results were as follows. 1. The incidence of chlamydial infection among neonatal conjunctivitis was 34.6%. 2. The most common age at diagnosis was 6-15days of life and there was no secual preponderance. 3. There was no significant difference on clinical symptoms between chlamydial conjunctivitis and other conjunctivitis. 4. Of 26 infants examined, 16 cases revealed no growth on routine bacterial culture. Of the organism cultured, P. aeruginosa was the most common agent (19.2%) and followed by S. aureus (11.5%) and S. epidermidis (7.6%). In one case of chlamydial conjunctivitis, there was concurrent S. aureus infections. 5. On this study, Giemsa stain did not give significant diagnostic aid of chlamydial conjunctivitis.

Development of drug resistance in tumors during treatment is a major factor limiting the clinical use of anticancer agents. When tumor cells acquire resistance to anticancer drug, they show cross-resistance to other antitumor agents. In the present study, SNU-1 cell was induced adriamycin 10-7 drug resistance, SNU-1/ADR, in vitro culture system. We got the doubling time and number for viability test during 96 hours by MTT assay. To investigate the cross resistance of various anticancer drugs in human stomach cancer cell SNU-1 and SNU-1/ADR, We compared IC50 (drug concentration of 50% reduction) and the relative resistance (RR). SNU-1/ADR was expressed multidrug resistant with vinblastine (RR;>31.62), vincristine (RR;29.50), dactinomycin (RR;21.37), epirubicin (RR;17.78), daunorubicin (RR;14.12), adriamycin (RR;7.76), and etoposide (RR;4.46), and other drugs, 5-fluorouracil, cisplatin, cyclophosphamide, methotrexate, and calarubicin, have not cross resistant with adriamycin. There was double minute chromosome in SNU-1/ADR by karyotyping although this change was not seen in SUN-1.

The clincopathologic features of microcystic adnexal carcinoma are presented. Microcystic adnexal carcinoma is a recently described, very rare neoplasm characterized by a locally aggressive growth pattern, and as far as we know, only two reports on the microcystic adnexal carcinoma have been published in the Korean literature. Recently we experienced two cases of microcystic adnexal carcimoma occurred in a 32-year-old male and 27-year-old female patient. They had 2.5 x 2.0 x 2.0 cm and 1.2 x 0.9 x 0.9 cm sized, slowly growing mass in the glabella and below the lower lip, respectively. The immunohistochemical staining for CEA antigen stains the glandular structures but not pilar structures. So we thinked that this tumor would be originated from primitive adnexal cells differentiating into both pilar and eccrine structures.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) continues to be a major cause of nosocomial infection and a molecular typing is necessary for proper epidemiologic investigations of sources and moles of spread in an outbreak. An nosocomial outbreak of MRSA in a neonatal intensive care unit at Ewha Womans University Mokdong Hospital was suspected. To investigate the clonality of isolates and control the spread of nosocomial outbreak, we performed plasmid restriction analysis of MRSA isolates from patients and medical staffs. METHODS: We studied 7 MRSA strains (umbilicus 4, blood 1, urine 1 and pus 1) from patients in a neonatal intensive care unit and the MRSA strains from nares and hands surveillance cultures of 26 medical staffs (4 medical doctors and 22 nurses). All MRSA strains were tested for antimicrobial susceptibility and plasmic analysis after EcoRI restriction. We analyzed the plasmid patterns of MRSA isolated from patients and compared with those from medical staffs. RESULTS: Ten MRSA strains (from 7 nares and 3 hands) were isolated from surveillance cultures of 26 medical staffs. Seven out of 10 MRSA strains from medical staffs revealed identical pattern of antibiogram which was the same pattern in all 7 MRSA strains from seven patients. Plasmid restriction patterns were classified 6 groups from A to F showing 2-10 bands. Six out of 7 MRSA strains from the patients showed group A(A1 5, A31) and 5 out of 10 MRSA strains from the medical staffs showed group A(A1 1, A21, A32, A41) and remainders showed different plasmid restriction analysis patterns. CONCLUSIONS: These results suggest that plasmid restriction analysis is a rapid, inexpensive, and good discriminating molecular typing of MRSA outbreak and is useful for the epidemiologic investigation of MRSA outbreaks in the clinical laboratory.

6.Career Path Education System at the College of Medicine, The Catholic University of Korea
Korean Medical Education Review 2024;26(1):19-26
This study examines a systematic and effective approach to career guidance in medical education, with a particular focus on the 6-year integrated career guidance education framework implemented at the College of Medicine, The Catholic University of Korea. Based on the “New SLICE” educational development principles, this framework comprehensively addresses the needs of medical students in career planning and development. It is structured into three phases: understanding yourself, exploring options, and choosing a specialty. The first phase, understanding yourself, helps students to recognize their strengths, weaknesses, aptitudes, and potentials, thereby setting the direction for future career choices. This phase includes various psychological tests and Self-Development and Portfolio courses. The second phase, exploring options, enables students to engage in related activities such as research and practical training, providing direct and indirect experiences across various fields. This phase offers courses including Medical Field Experience, Career Guidance through the Learning Community & Advisory Professors, and Student Participation in Professor Research Projects. The final phase, choosing a specialty, involves students making decisions based on in-depth self-assessment and exploration of majors, with a capstone project being a significant component. Maximizing the efficiency of career decision-making requires integration between the basic medical curriculum and postgraduate education. Including the period up to residency entrance in the framework is necessary for effective career guidance education.

PURPOSE: The purpose of this study was to describe the ultrasonographic features and assess the diagnosticvalue of sonography in the evaluation of children with Henoch-Schonlein purpura. MATERIALS AND METHODS: BetweenOctober 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography,which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in thethickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites wereevaluated. RESULTS: In 42 cases(63%), sonographic findings were positive, and indicated mesentericlymphadenopathy(n=21), small bowel wall thickening(n=20), and ascites(n=17). Thickened bowels were demonstrated atthe ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum andjejunum in two ; thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10mm(mean :6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesentericlymphadenopathy or ascites, and correlated well with improved abdominal symptoms. CONCLUSION: Abdominalultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesenteric lymphadenopathyand ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation ofHenoch-Schonlein purpura.

Digital therapeutics is an evidence-based intervention using high-quality software, with the sole purpose of treatment. As many healthcare systems are encountering high demands of quality outcomes, the need for digital therapeutics is gradually increasing in the clinical field. We conducted review of the implications of digital therapeutics in the treatment of neurological deficits for stroke patients. The implications of digital therapeutics have been discussed in four domains: cognition, speech and aphasia, motor, and vision. It was evident that different forms of digital therapeutics such as online platforms, virtual reality trainings, and iPad applications have been investigated in many trials to test its feasibility in clinical use. Although digital therapeutics may deliver high-quality solutions to healthcare services, the medicalization of digital therapeutics is accompanied with many limitations. Clinically validated digital therapeutics should be developed to prove its efficacy in stroke rehabilitation.

BACKGROUND AND PURPOSE: Little is known about the relationships between provoking risk factors, prognosis, and optimal duration of anticoagulation in patients with cerebral venous thrombosis (CVT), especially in Asians. We aimed to investigate whether the prognosis and required duration of anticoagulation in CVT patients differ according to the provoking risk factors. METHODS: Prospectively recorded data from a tertiary medical center in South Korea were retrospectively reviewed. CVTs were categorized into three groups: unprovoked, those with possibly resolved provoking factors (PR), and those with persistent provoking factors (PP). The baseline characteristics, treatment, and prognosis of patients in these three groups were analyzed. RESULTS: From 2000 to 2015, 61 patients presented with CVT: 19 (31.1%) unprovoked, 11 (18.0%) with PR, and 31 (50.9%) with PP. The patients in our cohort had a slight female predominance and lower frequency of oral contraceptive use compared to Western cohorts. Median follow-up and duration of anticoagulation were 35 and 8 months, respectively. Despite the similarities in baseline characteristics, deaths (n=3; P=0.256) and recurrences (n=7; P=0.020) were observed only in the PP group. The median intervals to death and recurrence were 9 and 13 months, respectively. Death was associated with underlying disease activity, not with CVT progression. Recurrences in the PP group were associated with lack of anticoagulation (P=0.012). CONCLUSIONS: Although the prognosis of CVT is generally benign in Koreans, recurrence and death were observed in patients with persistent risk factors, suggesting their need for long-term treatment with anticoagulants.
