The purpose of this study is to review epidemiological and clinical characteristics of diverticular disease of the colan in Korea and to discuss the difference of the findings from those in other countries. Reviewing all thebarium enema films taken at the Seoul National University Hospital retrospectively for the last 8 years. that is, from January 1, 1980 to December 31, 1987, we observed the annual and overall incidence of the disease, the number and location of the diverticula, and the presenting symptoms of the cases. The results are summarized as follows: 1) Out of the patients examined, 237 cases had one or more diverticula in the colon, the overall incidence being 1.32%, 2) The annual incidence increased progressively for the last 8 years, from 0.25% in 1980 to 2.53% in 1987. 3) The mean age of the patients at the time of diagnosis was 51 years. The male to female ratio was 2.5. 4) The diverticula were located on the right side in 81.0% of the cases, on the left side in 10.6%, and on both sides in 8.4%. 5) In 82 cases (34.6%) single diverticulum was found, whereas 34 cases (14.3%) had more than 10 diverticula. 6) The most frequent symptoms for taking barium enema were abdominal discomfort and pain (34. 2%) and changes in bowel habits (33.8%}, whereas 45 casea (19.0%) had the examination just for a routine health check. In conclusiion, the diverticular disease of the colon is still uncommon in Korea as compared with in western countries, and the right colon type is far more freqtaent than the left colon type. However in recent years the incidence increases quite rapidly and the left colon type is getting more common.

BACKGROUND: Head injury is one of the most common causes of emergency department visits and hospital admission in the pediatric populations, and most injuries are mild. In mild head injury, grading of severity and decision of hospital admission are difficult in the emergency department. Recent studies have suggested that patients with a normal head CT scan and neurologic exam following head injury can be safely discharged from the emergency department. However, previous studies have relied on incomplete patient follow-up and been limited for the most part to adult population. So we performed this study to assess clinical course and the incidence of significant CNS sequelae in children with a normal head CT scan and no focal neurologic sign after mild head injuries during hospital admission and follow-up for 1 month. METHODS: We reviewal the records of children(n=209) admitted to the department of emergency medicine with closed head injuries from Jan. 1, 1996 to Dec. 31, 1996, who's initial Glasgow Coma Scale was 13 to 15, and have no focal neurologic sign and a normal head CT scan. RESULT: 209 patients were studied with a mean age of 6.8(range 3 months to 15years), and 66.5% were male. The most common mechanisms of injury were pedestrian T.A(50.2%) and fall(11.5%). Patients had a mean Glasgow coma scale of 14.8 and mean Abbreviated Injury Score of 1.3. Patients had clinical symptoms of headache(49.3%), vomiting(44.5%), loss of consciousness(LOC)(29.6%), amnesia(10.0%), sleepiness(8.6%), irritability(8.6%), confusion(2.9%) and seizure(1.9%). The mean duration of admission was 4.3 days(range: 6 hours-20 days) and the mean duration of symptom was 36.4 hours. No child developed significant CNS sequelae during hospital admission. However, during hospital admission, aye children(all were preschooler) had psychologic complication ; one child developed post-traumatic stress disorder requiring psychologic treatment for 3 months. Three children developed enuresis and two children developed night terror. During 1 month fallow-up, one child developed a symptomatic hemorrhagic contusion 5 days after the head injury, not requiring neurosurgical treatment. CONCLUSION: Among children with an initial Glasgow Coma Scale of 13 to 15, a normal head CT scan and no focal neurologic sign after mild head injuries, delayed intracranial sequelae are extremely uncommon. So these patient may be discharged home with parental supervision and education for dose observation.

Many patients whose chief complaint is headache caused by accident such as traffic accident, falling, or assaults visit to emergency center. Majority of these patients has mild or moderate symptoms, and there is no need to treat surgically. However, the fact that head injury can cause SIADH(syndrome of inappropriate secretion of antidiuretic hormone) is likely to be overseen. Acute hyponatremia might have been associated with death or permanent brain damage. Hyponatremia is best handled by early recognition and correction of a downward trend in the serum sodium. Unfortunately, this is often difficult in the head-injured patient, where hyponatremia may occur fairly rapidly and is confused by symptoms of head injury. when moderate to severe hyponatremia occurs, it is important to determine its etiology and expeditiously initiate corrective action. There has not been any reported case of the occurrence of symptomatic SIADH after mild head injury in Korea yet. The authors report the experience of three cases of symptomatic SIADH after mild head injury with review of the literatures.

In order to identify the correlations between clinical results and quantitative data of gait analysis, we analyzed the results of 20 cases of total knee joint replacement arthroplasty in 15 patients with degenerative arthritis. We also evaluated the gait analysis of ten age-matched healthy candidates as a control group. Mean follow-up periods were 30 months. Clinical results included post-operative HSS (Hospital for Special Surgery) knee rating scores and the changes of the tibiofemoral angles. The three dimensional gait analysis included clinical assessment, video-taping, three dimensional kinematics and kinetics. The three dimensional kinematics were obtained using a 5 camera VICON system, and the three dimensional kinetic data was collected using two AMTI force plates. There was no statistical difference in linear parameters between the patient and control group. In patients group, however, double support time decreased as the HSS score increased, and range of knee motion and maximum knee flexion increased in accordance with the increase of pain score. Kinematic data of the patients group revealed that some parameters, such as knee flexion during loading response, knee flexion in swing phase, and knee varus during swing phase, were decreased. On the other hand, internal rotation of the knee from initial contact to initial swing was increased when compared with that of control group. There was no significant correlation between the degrees of tibiofemoral angle and coronal plane moment in the patients group. In three cases which showed mild varus instability post-operatively, knee flexion during loading response decreased and valgus moment in midstance increased as compared with the cases without instability. We believe that three dimensional gait analysis will be a good modality for evaluation of the results after total knee arthroplasty. With further accumulation of long term. follow-up data of gait analysis, we might be able to predict the long term results of total knee arthroplasty including possibility of loosening.

BACKGROUND: Puffer fish can be the source of lethal flood poisoning in humans. Tetrodotoxin(TTX) poisonings are not infrequency seen in Korea, but there are few clinical reports. So we reviewed the patients of TTX poisoning and analyzed the clinical characteristics of patients. METHODS: A retrospective study was performed of 40 patients who visited Chung Ang Gil Hospital from Jan. 1, 1995 to May. 31, 1998 with a diagnosis of TTX poisoning by a review of patients' medical records and telephone inquiries, The diagnosis of TTX poisoning was made by causal links between consumption of puffer fish and the development of typical symptoms of tetrodotoxication. The clinical severity of the patients in this study was classified according to the classification of Fukuda. RESULTS: Mean age of the patients was 40 years. The highest incidence was in the 4th decade in 21 patients(52.5%). The ratio of male to female was 3.44:1, Seasonal distribution excluding cases in 1998 was 12 patients in spring, 6 in summer, 5 in autumn and 12 in winter. The mean interval between consumption and symptom onset was 137 minutes. Common initial symptoms were circumoral numbness(32 patients) and paresthesia of extremities(24 patients). Various symptoms were developed after ingestion of puffer flesh such as neuromuscular(39 patients), cardiovascular/pulmonary (23 patients) and gastrointestinal (16 patients) system. Mean recovery time from the onset of symptom was 22.00 hours. All were treated with symptomatic and supportive measures and recovered completely without sequelae. In 2 cases ventilatory supports were applied for 18.5 hours and 31.5 hours respectively.

The P19 embryonal carcinoma cell line is a useful model cells for studies on cardiac differentiation. However, its low efficacy of differentiation hampers its usefulness. We investigated the effect of 5-azacytidine (5-aza) on P19 cells to differentiate into a high-efficacy cardiomyocytes. Embryoid-body-like structures were formed after 6 days with 1 micrometer of 5-aza in a P19 cell monolayer culture, beating cell clusters first observed on day 12, and, the production of beating cell clusters increased by 80.1% (29 of 36-wells) after 18 days. In comparison, the spontaneous beating cells was 33.3% (12 of 36-wells) for the untreated control cells. In response to 1 micrometer of 5-aza, P19 cells expressed bone morphogenetic protein-2 (BMP-2), BMP-4, Bmpr1a and Smad1 at day 6 or 9, and also cardiac markers such as GATA-4, Nkx2.5, cardiac troponin I, and desmin were up-regulated in a time-dependent manner after induction of BMP signaling molecules. Immunocytochemistry revealed the expression of smooth muscle a-actin, sarcomeric a-actinin, cardiac myosin heavy chain, cardiac troponin T and desmin, respectively. The proportion of sarcomeric a-actinin positive cells accounted for 6.48% on day 15 after 5-aza exposure as measured by flow cytometry. This study has demonstrated that 5-aza induces differentiation of P19 cells into cardiomyocytes in a confluent monolayer culture in the absence of prior embryoid formation and dimethyl sulfoxide exposure, depending in part on alteration of BMP signaling molecules. These results suggest that 5-aza treatment could be used as a new method for cardiac differentiation in P19 cells.

Recent studies have shown that side population (SP) cells, isolated from adult myocardium, represent a distinct cardiac progenitor cell population that exhibits functional cardiomyogenic differentiation. However, information on the intrinsic characteristics and endothelial potential, of cardiac SP cells, is limited. The present study was designed to investigate whether cardiac SP cells exhibit endothelial differentiation potential. The cardiac SP cells more highly expressed the early cardiac transcription factors as well as endothelial cell markers compared to the bone marrow-SP cells. After treatment with VEGF, for 28 days, cardiac SP cells were able to differentiate into endothelial cells expressing von Willebrand factor as determined by immunocytochemistry. Furthermore, expression of endothelial cell markers increased several-fold in VEGF-treated cardiac SP cells compared to the control group when assessed by real-time PCR. We also confirmed that cardiac SP cells provided a significantly augmented ratio of ischemic/normal blood flow, in the cardiac SP cell-transplanted group compared with saline-treated controls on postoperative days 7, 14, 21 and 28, in a murine model. These results show that cardiac SP cells may contribute to regeneration of injured heart tissues partly by transdifferentiation into angiogenic lineages.

Purpose: Totally implantable venous access ports (TIVAPs) can be used long-term for safe administration of intravenous drugs. TIVAP complications include catheter-related infections, venous thrombosis, extravasation, TIVAP migration, and pain. The relationship between the timing of the first chemotherapy administration after port implantation and complications is controversial. This study aimed to investigate the safety of immediate use of TIVAPs and the associated risk factors for complications. Methods: Between January 2016 and December 2018, 305 patients (median age, 53 years; 256 women) who underwent TIVAP placement at our institution were included. Chemotherapy was administered within 2 days of implantation. A retrospective analysis of patients’ clinical data was performed to investigate catheter days and complications of TIVAPs. Results: Overall, 305 patients were evaluated over 57,324 catheter days (median, 168 catheter days; interquartile range, 105). The median interval between placement and first use of TIVAPs was 0.98 days. The overall morbidity rate was 2.95%. Nine complications occurred in nine patients, including TIVAP-related infection (4), pain (2), port occlusion (1), thrombosis (1), and scar disunion (1), of which five required port removal (1.64%). The median number of catheter days before complications occurred was 61 (range, 10–457 days; interquartile range, 51). No complications occurred within 7 days of implantation. Body mass index was an independent risk factor for TIVAP-related complications in the Cox proportional hazards model (multivariable analysis: hazard ratio, 1.221; 95% confidence interval, 1.054–1.414; P = 0.008). Conclusion This study suggests the safe long-term use of TIVAPs following their immediate chemotherapy administration within 2 days of implantation.
