Purpose : Adenoviruses(Ad) have been shown to play an important role in the etiology of severely acute respiratory diseases, particulary in infants and young children, and the occurrence of fatal outcome and chronic pulmonary sequelae in association with adenoviral infection has been a cause of great interest and concern. This report presents the resul of a retrospective analysis on 30 cases of lower respiratory infection from which adenovirus was isolated. Patients & Methods : The 30 patients in this study represent all detected cases of adenovial infection out of 240 children who were admitted to Sang Sung Medical Center between February to June 1996 showing signs and symptoms of lower respiratory tract infection. The diagnosis of adenovirus infection was based on microscopic visualization of typical cytopathic effect in HEp-2 tissue culture and used monoclonal Ab with nasopharyngeal aspiration. Results : The male/female ratio was 2:1 and the majority of age range was below 36months. Clinical diagnoses in all 30 patients were pneumonia(n=21), bronchitis and Bronchiolitis(n=5) and ARDS(n=4). We recieved the most of patients in the month of May. The chief complaints were fever(93.3%) and cough(80%) and extrapulmonary symptoms were diarrhea(n=5), seizure(n=4), abdominal pain(n=1). The mean duration of fever was $11.95{\pm}6.54$days. Physical examination on admission were crackles(73.3%), coarse breathing sounds(60%), hepatosplenomegaly(33.3%), decreased brething sounds(30%). In WBC counts, 8cases were below $4000/mm^3$ and 14 cases were above $10,000/mm^3$. In platelets counts, 4cases were below $150,000/mm^3$ and 10 cases were above $450,000/mm^3$. 21 cases were above 1 in CRP. GOT and GPT were abnormal in some cases. Chest X-ray revealed diffuse pulmonary infiltration(n=15), pleural effusion(n=6), consolidation(n=4) and hyperaeration(n=3). Seven patients were treated at the peditric intensive care unit with respiratory support and high dose of gammaglobulin. However, one patients died even through he was treated with NO ventilation and high frequency ventilation. Conclusion : Those with adenoviral pneumonia and respiratory infection having long fever duration and symptoms like bacterial pneumonia must be carefully differentiated in order to provide proper treatement and preventive measures due to possible fatal outcome.

This research is a field investigation to collect basic information about the safe and efficient use of physical restraint in hospitals and for the ultimate minimization of restraint use. The objects of this study were sixty-four patients. They were restrained physically. Add their 32 family members, 24 nurses of two university hospitals in Seoul were also involved in the study. From April 16, to May 27, 1999. Research data were collected throughout the observation and interview process. Also, the data was analyzed using frequencies and field study notes that were invented by researchers. Results of this study were as follows: 1. According to the sex and age distinction; male's restraint use was 75%, female's was 25% and pre-schoolage children 39.1%, middle age 26.5%, and senior citizens 20.3%. According to the disease distinction; neuro-system was 35.9%, respiratory system was 21.9%. In the Ward, 40.6% of ICU patients were restrained and 39.0% of pediatric ward children were also to restraint. 70.3% of patients were restrained under 5days, while 10.9% were restrained 10days. 2. Types of physical restraints were wrist restraint (45.21%), arm board (35.62%), leg restraint (8.22%), chest restraint (6.85%), elbow restraint (2.74%) and mitten restraint (1.37%). 3. The percentage was 3.5%, which was in 64 restrained out of 1828 hospitalized people. At 1st investigation, the ratio was 3.5%, the 2nd was 3.0% and the 3rd was 3.9%. 4. The reasons of using the physical restraint were 'to protect implements' (72.84%), 'to protect patients' (18.52%), 'to protect an operative site' (8.64%). 5. The result of the patients; family and nurses' response analysis was: 'It seems to be safe', 'It uses properly', 'It is convenient for relatives and nurses', 'It is helpful to treatment', 'Objective think it is not restraint' were 79.9%. 'It is discomfort and stuffy', 'The implement is ineffective' were 21.1%. However in interview of the patients who can do verbally communication, 6 of 7 was responded that 'It is stuffy and uncomfortable'. 6. When restraint is used, the main decision is usually made by the nurses 42.2% of the time. The statistics read as thus: nurses and the physician in charge 31.3%, nurses and family 12.5%, physician's order 7.8%, only family 6.2%. Although the record of restraint was only 15.6% so that only 10 cases out of all the 26 ICU patients restrained. This study shows that physical restraints which of infringe independent-right of patients, are used without using criterion, explaining the agreement. Also, subjective decision of physician, nurses, and family make the decision of using restraint. So development of practice manuals and rules for restraint implementation is urgent.

Essential metals have been known to interact with non-essential toxic metals in the aspects of absorption, transport and deposition in the body. Iron deficiency has been reported to increase lead and/or cadmium absorption. The relation between iron and lead has been understood well in children but not in adults. Two hundred seventy adults (118 males and 152 females) were recruited from 3 different residental areas (rural, coastal and urban) to investigate the effects of environmental lead exposure on body iron status. The subjects were interviewed for life-style and diet of the last 24 hours, and measured for blood lead and body iron. The lead concentration in the whole blood was determined by a flameless method using an atomic absorption spectrophotometry. The body iron was evaluated with values of hemoglobin, hematocrit, RBCs, serum total iron, unsaturated iron binding capacity, total iron binding capacity and ferritin. The mean concentration of blood lead in adult was $3.31{\mu}g/dL$. The concentration was higher in male ($3.97{\mu}g/dL$) than in female ($2.86{\mu}g/dL$). The blood lead was influenced by residental area, life-style, smoking and drinking, occupation and diet habit of subjects, but not by age. A positive correlation was observed between the blood lead level and the serum iron or ferritin. These results suggest that environmental lead exposure in Korean adult may not be higher than other developed and developing countries. It is further indicated that blood lead in adult could be influenced by life-style, and environmental and genetic factors but no inverse relation with body iron as shown in children.

The incidence of Adenovirus(AV) pneumonia in children is estimated at 8%. Long-term complications reported with type 7 include hyperleucent lung syndrome, bronchiolitis obliterans and may require several months to recover. We reviewed 8 case of AV pnemonia confirmed by AV culture and sero-diagnosis among selected 19 AV pneumonia suspicious cases who were admitted to the Sanggye Paik Hospital of Inje University due to clinical pneumonia from May to July 1996. From 19 children, nasal aspirates or trachial aspirates were collected: viral agents were detected by virus isolation and virus antigen was detected by indirect immunofluorescent staining. Serologic diagnosis for type-specific AV antibody was done by neutralisation test. The results are as follows: 1) Age of the patients ranged from 6 months to 47 months with a mean of $24{\pm}9$ months. 6 were male and 2 were female(M:F= 3:1). 2) Monthly distribution showed 4 cases on June, 2 cases on May and July, respectively. 3) The mean duration of admission was 20.4 days and mean duration of fever was 11.3 days 4) Peripheral leukocyte counts were elevated in 4 cases(50%) and findings of shift to left were showed in 4 cases(50%) and serum aminotransferase activities were elevated in 6 case(75%). 5) Radiologic findings include linear and streaky infiltration(1/8 cases), patchy and lobar consolidation (7/8 cases), pleural effusion(2/8 cases) and hyperleucency was seen in 3/8 cases at time of admission and increased to 6/8 cases on hospital discharge. 6) The AV serotypes were type 7, type 3, and type 1. 7) Oxygen supply was done in 4 cases(50%) and all 8 patients include 2 cases of type 7 treated with artificial ventilator were survived. In conclusion, the serotypes of AV pneumonia outbreaks in early summer of 1996 were type 7, 3, 1 and, as showed severe clinical course, continued follow up surveillance is necessary to the long term pulmonary complications.

An epidemiological survey on Metagonimus yokogawai infection was performed in the eastern coast area of Kangwon province. Formalin-ether concentration technique and Stoll's dilution egg counting method were employed to figure out the prevalence and intensity of M. yokogawai infection and eating habits of inhabitants with raw freshwater fish. The results are summarized as follows: 1. The prevalence rate of M. yokogawai infection was 6.6% among a total of 2, 357 examinees; 8.6% (115 out of 1, 345) in male and 4.0% (40 out of 1, 012) in female. 2. The prevalence rates were different by the streams where the examinees were residing: 17.8% along the area of Ohsip-cheon (stream), 11.8% along Maeup-cheon, 1.7% along Hwasang-cheon, 1.3% along Yeongok-cheon, 0.9% along Namdae-cheon, 0.9% along Sa-cheon and 0% in the other streams (Yongchon-cheon, Kangnung Namdae-cheon and Jusoo.cheon) in decreasing order. 3. By social strata, the positive rate was 8.0% (122 out of 1, 521) in general inhabitants and 3.9% (33 out of 836) in school children. 4. By the intensity of infection by means of EPG counts in feces; the light infection (less than 400/EPG) was 74.1%, moderate infection (401-1, 000/EPG) 17.3% and heavy infection (more than 1, 001/EPG) 8.6%. 5. Twelves out of 50 sweetfish (Plecoglossus altivelis) (24%) caught from the streams in eastern coast of Kangwon-Do were infected with metacercariae of M. yokogawai, and the number of larvae detected were 70.7 per 6sh in average. The metacercarial infection rates in fish were also different by the streams; 100% in Ohsip-cheon of Samcheok-Gun, 14.3% in Sa-cheon, 16.7% in Yeongokcheon of Myeongju-Gun and 0% in Namdae-cheon of Yangyang-Gun, respectively. 6. Six hundred ninety live (695) out of 1, 396 inhabitants and school children (49.8%) were experienced in eating raw freshwater fishes (Plecoglossus altivezis, Triboledon hakonensis, Coreoperca sp., Morose sp., Carassius sp. & Cyprinus sp. and Zacco platypus). The data were assayed with the questionnaire collected from the examinees. In summarizing the above results, it is known that the Ohsip-cheon area of Samcheok-Gun is highly infected region, and the other areas of Kangnung Namdae-cheon, Yeongok-cheon and Yangyang Namdae-cheon are very lowly infected or non-infected regions for M yokogawai infection.

Purpose : Vesicoureteral reflux(VUR) is the major risk factor of urinary tract infection(UTI) in children and may result in serious complications such as renal scarring and chronic renal failure. The purpose of this study was to evaluate the relationship between VUR and renal scar formation, the usefulness and correlation of various imaging studies in reflux nephropathy, and the spontaneous resolution of VUR. Methods : We retrospectively reviewed 106 patients with VUR with no accompanying urogenital anomalies in the Department of Pediatrics, Bundang CHA Hospital during the period from Jan. 1996 to Mar. 2005. Ultrasonography and $^{99m}Tc$-dimercaptosuccinic acid(DMSA) scan were performed in the acute period of UTI. Voiding cystourethrography(VCUG) was performed 1 to 3 weeks after treatment with UTI. Follow-up DMSA scan was performed 4 to 6 months after treatment and a follow-up VCUG was performed every 12 months. Results : The mean age at detection of VUR was $13.8{\pm}22.2$ months and the male to female ratio was 2:1. The incidence of renal scarring showed a tendency of direct correlation between severity of VUR(P<0.001) and abnormal findings of renal ultrasonography(P<0.01). 63.2%(24 of 38 renal units) of renal parenchymal defects present in the first DMSA scan disappeared on follow-up DMSA scans. Follow-up DMSA scans detected renal scars in 7(14%) of 50 renal units with ultrasonographically normal kidneys. Meanwhile, ultrasonography did not show parenchymal defects in 7(36.8%) of 19 renal units where renal scarring was demonstrated on a follow-up DMSA scan. The spontaneous resolution rate of VUR was higher(75%) in cases with low grade(I to III) VUR(P<0.01). Conclusions : The presence and severity of VUR and abnormal findings of renal ultrasonography significantly correlated with renal scar formation. DMSA scan was useful in the diagnosis of renal defects. Meanwhile renal ultrasonography was an inadequate method for evaluating renal parenchymal damage. Therefore, follow-up DMSA scans should be performed to detect renal scars even in children with low-grade VUR and normal renal ultrasonography.

Purpose: Meckel's diverticulum (MD) has various clinical manifestations, and diagnosis or selectection of proper diagnostic tools is not easy. This study was conducted in order to assess the clinical differences of MD diagnosed by scintigraphic and non-scintigraphic methods and to find the proper diagnostic tools. Methods: We conducted a retrospective review ofthe clinical, surgical, radiologic, and pathologic findings of 34 children with symptomatic MD, who were admitted to Gachon University Gil Medical Center, Inha University Hospital, and The Catholic University of Korea, Incheon St. Mary's Hospital between January 2000 and December 2012. The patients were evaluated according to scintigraphic (12 cases; group 1) and non-scintigraphic (22 cases; group 2) diagnosis. Results: The male to female ratio was 7.5: 1. The most frequent chief complaint was lower gastrointestinal (GI) bleeding in group 1 and nonspecific abdominal pain in group 2, respectively. The most frequent pre-operative diagnosis was MD in both groups. Red blood cell (RBC) index was significantly lower in group 1. MD was located at 7 cm to 85 cm from the ileocecal valve. Four patients in group 1 had ectopic gastric tissues causing lower GI bleeding. The most frequent treatment modality was diverticulectomy in group 1 and ileal resection in group 2, respectively. Conclusion: To diagnose MD might be delayed unless proper diagnostic tools are considered. It is important to understand indications of scintigraphic and non-scintigraphic methods according to clinical and hematologic features of MD. Scintigraphy would be weighed in patients with anemia as well as GI symptoms.
