In addition to general charceteristics of tibial fracture, segmental tibial fracture is commonly combined with extensive soft tissue injury, comminution and displacement with poor blood supply in its middle segment. According to recent reports, intramedullary nailing was regarded as the excellent method in the management of this kind of fracture. Twenty-one cases were treated at the department of Orthopaedic Surgery, National Medical Center from January 1980 to December 1987 and following results were obtained; 1. Most common type of fracture was Type I (38.1%). Almost all the fractures were accompanied by open wounds(85.7%) and GIIIB open wounds were 12 cases(57.1%). 2. A verage union time was 31.8 weeks(union rate, 76.2%) and showed marked difference between closed fracture(20.2 weeks) and GIIIB open one(38.6 weeks). 3. Better results were seen in 8 cases of intramedullary nailing(average union time, 24.2 weeks), while all the plating method showed non-union in 3 cases of open wound.

PURPOSE: Mycoplasma pneumoniae pneumonia (MP) is associated with the exacerbation, timing, and onset of asthma. The goal of this study was to elucidate the impact of MP on eosinophil-related hyper-reactive amplification in atopic children. METHODS: We studied 48 patients with MP (26 atopic, 22 non-atopic), between 3 and 12 years of age. Serial changes in blood eosinophil counts, serum interleukin-5 (IL-5), and serum eosinophil cationic protein (ECP) levels were measured in atopic and non-atopic children with MP upon admission, recovery, and at 2 months post-recovery. Serum IL-5 and ECP levels were measured by enzyme-linked immunosorbent assays; eosinophil counts were measured using an autoanalyzer. RESULTS: Serial changes in serum IL-5, ECP, and total eosinophil counts were significantly higher in atopic patients, relative to non-atopic controls (P< or =0.001). Serum IL-5 and ECP levels were significantly higher in atopic patients at all three time points tested, while eosinophil counts were higher in the clinical recovery and follow-up phases, but not in the acute phase. Furthermore, among atopic patients, serum ECP levels were significantly higher in the recovery and follow-up phases than in the acute phase. CONCLUSIONS: The present study demonstrated significant differences in eosinophil counts, serum IL-5, and serum ECP levels between atopic and non-atopic children with MP at admission, recovery, and 2 months after clinical recovery. These outcomes are suggestive of eosinophil-related hyperreactivity in atopic children, with this status maintained for at least 2 months after MP.

The purpose of the present study was to investigate the relationship of dental crowding to tooth size and arch dimension in Korean subjects. Two groups of dental casts with Class I molar relationship, were selected on the basis of crowding. One group, consisting of 82 pairs of study cast (29 males and 53 females), exhibited at least 7 millimeters of crowding in each arch. A second group, consisting of 82 sets of study cast (37 males and 45 females), exhibited normal occlusion with little or no crowding. Mesiodistal tooth diameters, and buccal and lingual dental arch widths were measured and compared between the crowding and normal occlusion groups. Significant differences were observed between the two groups not only in arch widths but also in tooth sizes. The results of the present study suggest that both etraction and expansion can be used as a treatment approach for the crowding cases.

Subcapsular renal hematoma without a history of trauma is uncommon, which has been reported with the association of underlying renal tumor, vascular or inflammatory disease. Recently, subcapsular renal hematoma has been reported to be a rare complication of acute pyelonephritis. If abdominal pain is acutely aggravated or hematocrit is rapidly decreased in the patient of acute pyelonephritis, subcapsular renal hematoma as a complication of acute pyelonephritis should be considered and confirmed by subsequent imaging studies. We report two cases of subcapsular renal hematoma as a complication of acute pyelonephritis.

A study was carried out to figure the cases and to observe the endemic status of clonorchiasis and metagonimiasis in endemic areas in Korea. Total 13,373 inhabitants living in 40 villages along 7 main rivers and 9 small streams were subjected to stool examination. They were selected randomly among the riverside population. Their specimens were examined both by cellphane thick smear method and Stoll's egg countung technique. This study was performed during the period from May 1979 to April 1980. The results obtained are as follows: The egg positive rate of any kind of helminths was 58.7% out of 13,373 examned cases, and the egg positive rates by each helminth were; Clonorchis sinensis 21.5%, Metagonimus yokogaqai 4.8%, large type Metagonimus eggs 0.4%, Ascaris lumbricoides 22.9%, Trichuris trichiura 35.2%, hookworm 0.2%, Taenia sp. 0.5%, Hymenolepis nana 0.07%, Paragonimus westermani 2 cases, Fasciola sp. 4 cases, Echinostoma sp. 1 case and Hymenolepis diminuta 1 case respectively. Many endemic foci of clonorchiasis were revealed along the 7 major rivers. The egg positive rates of each river basin differed from each other significantly; Nagdonggang 40.2%, Yeongsangang 30.8%, Seomjingang 17.3%, Hangang 15.7%, Tamjingang 15.9%, Geumgang 12.0% and Mangyeonggang 8.0%. The cases of clonorchiasis were estimated in range 830,000 to 890,000 in riverside areas of the 7 rivers. By grading the infection intensity, 64.7% was in Grade I(EPG 0-900), 28.6% in Grade II (EPG 1000-9,900), 5.5% in Grade III (EPG 10,000-29,900) and 1.3% in Grade IV (EPG over 30,000). The proportion of the cases in Grade III and IV was 6.8% among positive cases. Therefore 60,000 cases at least were regarded to suffer from it clinically. Males of 30-60 years of age showed higher positive rate and heavier burden of infection. This makes clonorchiasis more important socially because the patients lose their social productivity. A few endemic foci of metagonimiasis were detected newly by egg detection; Samcheong 28.5% egg positive rate, Uljin 21.3%, Yeuongdeog 46.3%, Milyang 6.7%, Yeongil 9.2% and Geoje 18.2%. The mean EPG values were in range of 320-7, 120 by the focus. The egg positive rate and proportion of EPG Grade varied greatly by the area, and mean proportion of the positive cases were 69.7% in Grade I, 24.1% in Grade II, 5.0% in Grade III and 1.2% in Grade IV. Males of 30-60 years were infected in higher rate also. The large sized eggs of Metagonimus were found also in upper basin of Hangang and Geumgang mainly. They were regarded as eggs of M. takahashii which is mediated by the cyprinid fishes. Its significance should be studied further. Clonorchiasis and metagonimiasis should be realized as important public health problems in Korea by their wide distribution, high prevalence rate and heavy infection intensity. Comprehensive measures against them are needed urgently.

BACKGROUND AND OBJECTIVES: No-reflow is an important phenomenon for limiting the prognosis of patients following primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Coronary stenting is the current standard procedure for primary PCI in AMI. However, stenting is suspected to cause more microembolization, and no-reflow phenomenon. This study was performed to elucidate the risk factors for the no-reflow phenomenon following primary PCI with stenting, in patients with AMI. SUBJCETS AND METHODS: The clinical, angiographic and procedure related parameters were reviewed in patients with AMI that had undergone primary PCI, with stent implantation, within 12 h of the onset of chest pain, at Seoul National University Hospital, Yonsei University Hospital Cardiovascular Center and Chungbuk National University Hospital (n=183). RESULTS: 29 patients (16%) showed no-reflow phenomenon (final TIMI flow grade less than 3). Conventional risk factors for coronary artery disease were not significant risk factors for the no-reflow phenomenon. In a univariate analysis, a high initial CK-MB level (>50 IU) (8.45% vs. 21.9%, p=0.04), low left ventricular ejection fraction (LV EF) (<50%) (19% vs. 5%, p=0.03) and long pre-dilatation balloon inflation time (>30 sec) (31% vs. 15%, p=0.04) were significant risk factors of the no-reflow phenomenon. A low LV EF and long pre-dilatation balloon inflation time were significant risk factors in a multivariate analysis. CONCLUSION: LV dysfunction at presentation and a long pre-dilatation balloon inflation time were independent risk factors for the no-reflow phenomenon following primary PCI with stenting for AMI. Preventive measures against the no-reflow phenomenon should be considered in patients with these risk factors.
