There is room for debate in appropriate diagnosis and treatment due to physiological and anatomical differences in pediatric facial bone fractures from that of adult's. The objectives of this article is to analyze for our clinical cases and to suggest the appropriate management of facial bone fracture in children. The study included 56 children who had treatment for the craniofacial fractures form March, 1990 to February, 1998. Their ages ranged from 3 to 15. There were 38 males and 18 females. Physical examination, simple x-rays, ultrasonograms and routine CT scans were used for diagnosis. Materials were classified into 28 nasal bone fractures, 4 nasoethmoidal fractures, 6 orbital fractures, 8 mandible fractures, and 10 zygoma fractures. Patients were treated with conservative treatment in 9 cases, with closed reduction in 28 cases and open reduction only, and 14 patients with open reduction and internal fixation using microplates and screws. 3 patients needed autogenous calvarial bone graft. Plates and screws were removed in postoperative 3-6 months. All patients had successful union of fractured bones without no specific complications, and normal bony growths were noticed during the 7 years follow up. We conclude that surgeons should be careful in diagnosis and management for the pediatric facial fracture due to anatomical variations and differences in fracture aspects. First, it is mandatory for surgeous to get accurate diagnosis and identify children's fracture and displacement through routine CT check up along with physical examination. Second, it is important to perform the minimally invasive technique or conservative treatment for the children with mild displacement so that it reduces the incidence of growth retardation which may be caused by extensive operation. However, application of rigid fixation is necessary in case of extensive bony displacement or bony defects because of poor coorporation in postoperative care. Third, plates and screws which were used for the internal fixation should be removed at 3-6 months after the surgery. Fourth, if bone graft is needed, it is better to use autogenous graft than allogeneous graft. Fifth, care for dentition and follow up for growth are necessary for growing children.

Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre-and post- procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drain efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were lower than than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we though that it will be very helpful to the treatment of patients as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

Fractures of the upper end of the humerus are common and account for 4% to 5% of all fractures. They occur more frequently in older patients. In older patient the fracture often results from a minor fall and can be extremely disabling and their management often demands experienced surgical skill and judgement. Fortunately, in 80% of upper humeral fractures none of the four major segment is significantly displaced. These lesions are amenable to simple treatment by early function exercises. In 15% to 20% of upper humeral fractures one or more of the major segment is displaced. They are often unstable, may not be reduced by closed method. Many different methods of open reduction and internal fixation has been used and are still employed. These include wire loops, screw, staples, plates, intramedullary nail, but adequate internal fixation was not easily achieved due to the osteoporosis, displacement and shape of fragment. We treated 8 cases of surgical neck fractures by Rush pin and tension band wiring method. We consider this method as effective, simple and rigid fixation technique to attempt early exercise and to restore normal range of motion.

Authors analyzed the findings of findings of chest radiographs and high-resolution CT(HRCT) of chronic mercury vapor poisoning in 12 patients who were diagnosed by previous working history for mercury-thermometer and high level of mercury in blood and urine. The purpose of this paper is to introduce the HRCT findings of chronic mercury vapor poisoning. Duration of mercury exposure was ranged from 10 to 41 months(mean, 21.8 months). Estimated value of serum mercury was ranged from 3.6 to 8.7µg/dl(mean, 5.3 µg/dl: normal value is less than 0.5µg/dl). Estimated value of mercury in urine was ranged from 104 to 482µg/1(mean, 291.4µg/1: normal value is less than 20µg/1). Chest radiographs showed positive findings such as ground-glass opacities and peribronchial cuffings in only 2 out of 12 patients, but HRCT showed positive findings such as ground-glass opacities in 8 patients, peribronchial cuffings in 7 patients, centrilobular abnormalities in 5 patients, interface sign in 4 patients, interlobular septal thickening with intralobular lines in 2 patients and lobular consolidation in one patient. In conclusion, chest HRCT is superior to chest radiograph to show the pulmonary manifestation of chronic mercury vapor poisoning. In patients with chronic mercury vapor poisoning, HRCT findings of centrilobular distributed ground-glass opacities and peribronchial cuffinges are characteristic.

This study was purosed to investigate maternal and fetal clinical parameters effecting on maternal serum alpha-fetoprotein(MSAFP) levels at late normal singleton pregnancies. The subjects of this study were 171 pregnant women with gestational age of 36 to 42 weeks, and didn`t have any medical or gynecologic diseases. They delivered fetuses within three days after blood test of MSAFP. MSAFP levels were measured by enzyme-immunoassay. The analysed clinical parameters included fetal sex, fetal weight, gestatioal age, maternal age, gravidity, parity, maternal weight and maternal total weight gain during pregnancy. The results were as follows: At uncomplicated late pregnancies, 1. Male fetus bearers had higher MSAFP(mean: 191.8 ng/ml, SD: 80.8 ng/ml, n=79) than female-fetus bearers(mean 153.6 ng/ml, SD 73.0 ng/ml, n=92)(p=0.0014). 2. Multiparas had higher MSAFP(mean: 192.7 ng/ml, SD: 77.9 ng/ml, n=80) than nulliparas(mean: 152.3 ng/ml, SD 75.1 ng/ml, n=91)(p=0.0007). 3. MSAFP did not have correlation with maternal age, maternal weight, maternal total wight gain during pregnancy, gestational age, fetal weight. According to the above results, fetal sex and parity are the factors that influences MSAFP levels at uncomplicated late pregnancies. So MSAFP values should be interpreted with cautions.

Condyloma acuminatum, a benign disease caused by a filtrable virus, occurs predominantly in the perianal andgenital areas. The lesions are noninvasive but are subject to recurrence. In rare instances, a more aggresive formof this disease, known as "giant condlyloma acuminatum" or "Buschke-Lownestein tumor", occures. In this form,infiltration of the lesion into surrounding structures takes place. This tumor has been reported to occurprincipally in the genitourinary tract. The authors experienced a cases of giant condyloma acuminatum originatingfrom rectum in 67 years old male patient which recurred 3 months after electrofulguration.

PURPOSE:To identify the main toxic gas released from salted radish in rice bran(Dan-Mu-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. MATERIALS AND METHODS: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. RESULTS: The radiographic examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headspace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. CONCLUSION: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.
