The authors analysed 340 cases of the ocular injuries among 7633 out and in-patients who visited to the clinic of P.N.U. hospital during 5 years, from Jan. 1964 to Dec. 1968. Followings were discussed. 1. We found that 4.6% of all cases attending our eyes clinic was victims of ocular injuries. 2. The sex incidence showed that 78.9% of such ocular injuries occured in male and 21.1% in female. 3. The incidence was prevalent in young adult 21-30 years of age, and their large number of cases were injured from blowing and industrial accidents, while in children under 10 years of age sharp-pointed toys were more frequent causes. 4. The subconjunctival hemorrhage was the most frequent disturbance of ocular injuries and then came traumatic cataract and corneal foreign bodies in that order. 5. The prognosis of ocular injuries was generally poor, especially, poor, especially in the perforating and penetrating wound of the whether the foreign body was retained or not.

PURPOSE: We evaluated the clinical characteristics of lower respiratory infections of preterm children with bronchopulmonary dysplasia (BPD) and compared them between those with and without lower respiratory infections that of preterm patients without BPD. METHODS: This study enrolled preterm patients under 2 years old, who admitted with acute lower respiratory infection from March 2014 to May 2016. The patients were divided into 2 groups according to BPD, and we retrospectively reviewed their medical records. RESULTS: A total of 71 patients (106 cases) were enrolled; the BPD group consisited of 29 patients (54 cases) and the control group 42 patients (52 cases). Compared to the patients in the control group, those in the BPD group were older (P=0.001), had lower gestational age and birth weight (P<0.001), and showed more frequent readmission in hospital (P=0.017). The most common causative virus was human rhinovirus (hRV) in the BPD group, whereas respiratory syncytial virus (RSV) in the control group. The patients in the BPD group showed a higher incidence of tachypnea, decreased aeration, and chest retraction (P<0.001, P=0.009, and P=0.026, respectively), a higher respiratory symptom score (P=0.011), a longer duration of cough and wheezy sounds (P=0.004 and P=0.009, respectively), and higher incidence and longer duration of treatment with oxygen, and mechanical ventilator support (P=0.016 and P=0.017, respectively) than those in the control group. In the BPD group, the patients with RSV showed a higher incidence of tachypnea and rales (P=0.033 and P=0.033, respectively) than those with hRV. CONCLUSION: The preterm children with BPD may have more severe clinical manifestations than those without.

We followed prospectively some hospital-delivered mothers to identify characteristics of those not initiated breast-feeding and predictors of breast-feeding discontinuation in monthly telephone interviews. Recruits were composed of 482 mothers who delivered their babies at one university hospital and one OB/GYN clinic in september to November 1991. Breast-feeding discontinuation was defined as switch to 100% formula lasting more than one week regardless of solid foods. Average age of the study subjects was 27.3 years of age(standard deviation 3.2). Multiple logistic regression analysis indicated native place, occupation, method of delivery and method of feeding considered to be better for maternal health were statistically significant(p<0.1) between initiators and non-initiators of breast feeding. In starting cohort(N=242) of those initiated breast-feeding, that median of breast-feeding discontinuation were 5 months and 25th and 75th percentiles were 3 and 9 months respectively. I Cox's proportional hazard model, mothers with 10~13 years of education were 2.63 times (95% confidence interval, CI 1.50~4.60 ) more likely to discontinue than those with less than 9 years of education and those with more than 13 years of education were 3.55 time (95% CI 1.99~6.33). Compared with house wife, mothers with part-time jobs were 1.99 times (95% CI 0.86~4.57) more likely to discontinue and those with employed full-time were 1.55 times (95% CI 0.96~2.51). These results suggest that the predictors of initiation and discontinuation of breast-feeding may be different and different target populations should be selected to promote initiation and to prevent discontinuation of breast-feeding according to the period after birth.

OBJECTIVE: We have developed an instant messenger system that supports transmitting 3D medical image objects for telediagnostic use. METHODS: We used thresholding and down-scaling technique to build down-scaled 3D object with 80 sliced Digital Imaging and Communication in Medicine(DICOM) images. And, we also construct instant messenger for medical data transfer and general communication. We measured total image size and transmission time which were decreased when applied peer to peer connection using instant messenger for medicine. RESULTS: Our study showed that total DICOM image size was decreased around 1% and transmission time was also decreased by 1.59% when we use proposed system. CONCLUSION: Proposed methods have a potential to be a useful tool in ubiquitous health network system. Also, we expect the synergy effect is increased by developing 3D object technique and security solutions.

Objectives : Recently, several attempts have been made to use repeated transcranial magnetic stimulation (rTMS) with various stimulation frequencies as a novel treatment for patients with obsessive-compulsive disorder (OCD). However, findings about the efficacy of rTMS in treating OCD have been inconsistent. In the present study, we evaluated the clinical effect and safety of low frequency rTMS on the right dorsolateral prefrontal cortex in the treatment of refractory OCD. METHODS : Twenty-four patients with treatment-refractory OCD received a daily treatment of 20 minutes low frequency rTMS (1 Hz) to the right dorsolateral prefrontal cortex with power of 100% of motor threshold, for 15 days. Clinical status was evaluated using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Hamilton Anxiety Scale (HAMA), and Clinical Global Impression (CGI) at baseline, at the end of the rTMS treatment (3 weeks), and 4 weeks after finishing the rTMS treatment course. RESULTS : After 3 weeks treatment with low frequency rTMS, Y-BOCS, HAMA and CGI-S scores were significantly decreased. CONCLUSION : The present study found that low-frequency rTMS on the right prefrontal cortex for 3 weeks showed significant therapeutic effects in patients with OCD. Further controlled trials are indicated to assess the efficacy of rTMS in the treatment of OCD.

Background/Aims: Sequential monotherapy is recommended for anthracycline-and taxane-resistant metastatic breast cancer (MBC), but combination chemotherapy is considered in patients with visceral crisis. Cisplatin-doublet chemotherapy is a combination regimen for MBC, but prolonged treatment is challenging because of toxicity. We analyzed the role of single-agent maintenance chemotherapy after cisplatin-doublet chemotherapy for MBC. Methods: From January 2011 to December 2017, 96 anthracycline- and taxane-resistant MBC patients were retrospectively reviewed, and 49 patients with a sustained clinical benefit during the initial 6 cycles of cisplatin-doublet chemotherapy were enrolled for study. Patients were treated with gemcitabine-cisplatin (gemcitabine, 1,250 mg/m2, intravenously [IV], days 1 to 8; cisplatin 60 mg/m2, IV, day 1) or capecitabine-cisplatin (capecitabine 2,500 mg/m2, orally, days 1 to 14; cisplatin 60 mg/m2, IV, day 1) during the induction period. After 6 cycles, 16 patients were switched to single-maintenance treatment (gemcitabine or capecitabine) and the doublet regimen was continued in 24 patients. Survival outcomes (progression-free survival [PFS] and overall survival [OS]) were analyzed. Results: Among the 49 patients who showed a clinical benefit during cisplatin-doublet therapy, 24 were maintained on the doublet regimen, 16 were switched to single-maintenance treatment, and chemotherapy was suspended until disease progression in nine patients. The single-maintenance chemotherapy group showed superior survival than the chemotherapy holiday and doublet regimen groups (median PFS 15.43 months vs. 8.37 and 10.67 months, respectively, p = 0.008; median OS 43.67 months vs. 22.17 and 22.33 months, respectively, p = 0.014). Conclusions Patients showing a clinical benefit during 6 cisplatin-doublet chemotherapy cycles may have a sustained survival benefit from single-maintenance chemotherapy.

Emergency department (ED) triage systems are used to classify the severity and urgency of emergency patients, and Korean medical institutions use the Korean Triage and Acuity Scale (KTAS). During the COVID-19 pandemic, appropriate treatment for emergency patients was delayed due to various circumstances, such as overcrowding of EDs, lack of medical workforce resources, and increased workload on medical staff. The purpose of this study was to evaluate the accuracy of the KTAS in predicting the urgency of emergency patients during the COVID-19 pandemic. Methods This study retrospectively reviewed patients who were treated in the ED during the pandemic period from January 2020 to June 2021. Patients were divided into COVID-19–screening negative (SN) and COVID-19–screening positive (SP) groups. We compared the predictability of the KTAS for urgent patients between the two groups. Results From a total of 107,480 patients, 62,776 patients (58.4%) were included in the SN group and 44,704 (41.6%) were included in the SP group. The odds ratios for severity variables at each KTAS level revealed a more evident discriminatory power of the KTAS for severity variables in the SN group (P<0.001). The predictability of the KTAS for severity variables was higher in the SN group than in the SP group (area under the curve, P<0.001). Conclusion During the pandemic, the KTAS had low accuracy in predicting patients in critical condition in the ED. Therefore, in future pandemic periods, supplementation of the current ED triage system should be considered in order to accurately classify the severity of patients.
