The author analysed foreign body in the airway, divided into two groups vegetable foreign body group(VFBG) and non-vegetable foreign body group(N-VFBG), according to the nature, in 88 patients aged from 5 months to 15 years who were diagnosed and treated under ventilating bronchos-copy at Department of Pediatrics and Otolaryngology, Pusan National University Hospital from 1980 to 1990. Of the 88 patients analysed, 13 were followed for review, which comprised clinical assessment, chest radiography, and perfusion lung scan. The follwing results were obtained. 1) The highest incidence was seen in the age group of 1 to 3 years old especially in VFBG, bur no difference in incidence among each age group was observed in N-VFBG, The ratio of incidence between male to female was 2:1 ein total and, in N-VFBG, the incidence of male 8 times higher than female. 2) A wide variety of foreign bodies was recovered, with peanut being by far the most common (50%) and the ratio of incidence between VFBG and N-VFBG was 6 to 4. 3) The time interval of less than 24 hours between aspiration and admission was most frequently seen in 38% and of more than 3 weeks in 11%. The time interval in VFBG and the group with left bronchial lodging was longer than of N-VFBG and the group with right bronchial lodging, each respectively but no statistical difference was observed. The time interval in the group with bronchial lodging was significantly longer than of the group with laryngeal and tracheal lodging. 4) Frequent symptoms and signs were coughing, dyspnea, fever, decreased air entry, coarse breathing sound and rales. In total, clinical manifestations were more common in VFBG, especially in the incidence of fever, decreased air entry, coarse breathing sound and rhonchi. 5) The roentgenographic findings on admission were emphysema, pneumonia and atelectasis in the order of frequency. The incidence of emphysema and complex roentgenographic findings were more common in VFBG whereas in N-VFBG radioopaque foreign body normal roentgenographic findings were more common. 6) The prevalence of bronchial lodging was over 70% regardless of age group. No difference of predilection was observed between right and left bronchial lodging before 7 years old, but after 7 years old right bronchial lodging was significantly seen. 7) The longer the time lag before admission after aspiration, the longer the duration of hospitalization was in VFBG but with no statistical significance. However, no correlation between time lag and the duration o hospitalization was observed in N-VFBG. The group with bronchial lodging had significantly longer duration of hospitalization compare to that of the group with laryngeal and tracheal lodging, The group with left bronchial lodging had longer duration of hospitalization compare to that of the group with right bronchial lodging but with no statical significance. 8) Of the 13 cases reviewed, one had abnormal lung perfusion scan in spite of normal clinical assessment and chest X-ray, who was treated on 20 days days after aspiration of peanut in the right bronchus.

The bone is the dynamic living tissue which is always maintained bone mineral content by bone resorption and formation. It has been well known that the bone mineral content is decreased very slowly with aging. It is very difficult to diagnose the osteopenia because it is almost subclinical. Another important problem in the osteopenia is the fracture occurring spontaneously. The quantitative method of bone mineral mass provide an information to diagnose the osteopenia and predict the risk of spontaneous fracture. Various methods have been used to access the degree of bone atrophy but have not been routinely available for clinical application in the hospital. The microdensitometric method is a noninvasive, easy, accurate, and objective one to monitor the degree of changes in the skeletal mass quantitatively. So, we measured the 7 indices at the middle site of the 2nd metacarpal bone with a microdensitometer and computer on an X-ray film of the hands and studied the correlations between the age and indices of those under 30 and over 30 yrs old in healthy and fracture groups. The results were obtained as follows : 1. There was a significant high correlation between age and indices in healthy and fracture groups. 2. The measurement of age by microdensitometric method was highly correlated with the chronological age. 3. Comparing both groups, There was a significant correlation of D (P<0.001), MCI(P<0.01), and d (P<0.01) over 30 yrs in male and GSmin (P<0.001) and ΣGS/D (P<0.01) over 30 yrs in female. 4. In fracture group, 1) The index of bone width(D) was slightly larger than in the healthy group. 2) The metacarpal index(MCI) was lower than in the healthy group. 3) The index of medulla width(d) was wider than in the healthy group. 4) The density index of cortex(GSmax) was smaller than in the healthy group. 5) The density index of cortex and medulla(GSmin) was smaller than in the healthy group. 6) There was no considerable difference in ΣGS/D between healthy and fracture groups. 7) The densitometric pattern was more aggrevated than in the healthy group.

Lymphomatoid papulosis is a chronic disease of cutaneous atypical lymphoid infiltration characterized clinically by involuting and recurring papules, plaques, and sometimes nodules. A 51-year-old man presented with a single, coin sized, nontender, erythematous nodule on the left thigh of a 2-week duration. There was a history of recurrence and spontaneous healing of similar asymptomatic eruptions five to six times over 20 years. A biopsy specimen showed a dense, wedge-shaped dermal infiltrate that was patchy and perivascular. The cellular infiltrate was polymorphous and consisted of large atypical cells, small lymphocytes, eosinophils and neutrophils. The large atypical cells were strongly CD30(Ki-1) positive. We report a case of lymphomatoid papulosis unusually presenting as a single nodular eruption, in which the differential diagnosis between lymphomatoid papulosis and CD30(Ki-1)positive large cell lymphoma is exceedingly difficult.

Lipodystrophia centrifugalis abdominalis infantilis, an typical form of progressive lipodystrophy, is a disease mainly decribed in japanese infants. We report a case of lipodystrophia centrifugalis abdominals infantilis in Korean infant. The patient is a 2 year-old-girl with a coin sized well defined depressed lesion with surrounding redness and scaly changes in the right inguinal region. The skin from the depressed lesion revealed changes similar to those originally described by Imamura et al.

We herein report a case of gout, who was a 45-year-old man and had had multiple various-sized papules or tophi on the helices of ears, hands, elbows, knees, ankles and feet for 10 years. Histopathologic findings of the large tophus of right knee revealed the typical pattern of gout with needle-shaped urate crystal. The phenomenon of iransepidermal elimination was observed in serial sections of histologic speeirnerls, The nsrrow transepidermal channel, lined by pseudoepitheliomstous lips bilaterally, was Eilled with the cellular debris and urate crystal fragments and cornmunicated direotly with the upper dermis. Presumably, transepidermal elirnination in gouty tophus may be the phenomenon whieh could be found rnore commonly than the scarcity of literature.

PURPOSE: To evaluate the clinical efficacy of amniotic membrane transplantation and limbal-conjunctival autograft for patients with recurrent pterygium or pseudopterygium, the results of 15 eyes of 14 patients were analyzed. METHODS: Total 10 cases of recurrent pterygium and 5 cases of pseudopterygium were surgically managed during June 1998 to July 2000. After excision of pterygium, amniotic membrane was attached on the bare sclera and limbal-conjunctival autograft was transplanted over the amniotic membrane. Mean follow-up period was 47.2 week and all patients were examined for recurrence, which was graded from G0(no vessel) to G3(fibrotic tissue invading the limbus). RESULTS: 12 out of 15 cases(rate 80%) showed no recurrence(grade 0). 1 case of grade 2 recurrence and 2 cases of grade 3(total 3 cases) were observed(rate 20%). Reoperation was performed on 2 cases of grade 3 recurrence. There was no further recurrence necessitating additional reoperation. 1 case of limbal graft was detached and removed. The operation time of this more prolonged than the other procedures, but there were no significant complications. CONCLUSION: Amniotic membrane and limbal-conjunctival autograft for patients with recurrent pterygium or pseudopterygium reconstructed complete ocular surface with less recurrence. Therefore, we recommend this surgical approach as a safe and effective method for the treatment of complicated cases of pterygium.

Purpose: In this study, we investigated whether the antigenic changes of the virus-like particles (VLPs) are affected by the temperature during storage. Materials and Methods: After exposing the recombinant influenza VLPs to various temperatures for a period, antigenic changes were examined through in vitro hemagglutination receptor binding assay and in vivo mouse experiments. Results: Influenza VLPs were exposed at three different temperatures of low, middle, and high on a thermo-hygrostat. High temperature exposed influenza VLPs were showed significantly reduced HA activity and immunogenicity after mouse single immunization over time compared low and middle. When the VLPs exposed to the high temperature were inoculated once in the mice, it was found that the immunogenicity was significantly reduced compared to the VLPs exposed to the low temperature. However, these differences were almost neglected when mice were inoculated twice even with VLPs exposed to high temperatures. Conclusion This study suggests that similar protective effects can be expected by controlling the number of vaccination and storage conditions, although the antigenic change in the VLP vaccines occurred when exposed to high temperature.
