Tracheobronchial aspergillosis is an unusual form of invasive aspergillosis characterized by noninvasive or only superficially invasive tracheobronchitis with a propensity for dissemination. We report a two-year-old male who suddenly died of respiratory failure. Postmortem examination revealed a pseudomembrane covering the mucosa of larynx, trachea and bronchial tree of both lungs. This pseudomembrane was composed predominantly of Aspergillus hyphae. There was transmural necrotizing bronchitis with fungal invasion to the narrow zone of peribronchial tissue, and dissemination to the stomach and kidney. This form of pulmonary aspergillosis had not been reported in this country.

PURPOSE: High flow rate (FR) and pressure limit (PL) strategy with time-cycled pressure-limited (TCPL) ventilator is employed routinely in the neonates. Theoretical basis of this strategy is the two-compartment theory that the lung with acute respiratory failure consists of units with different compliance and resistance. But such constant pressure strategy has the risk of ventilator induced lung injury. We compared the ventilatory indices and clinical outcomes of two different strategies, high FR-constant pressure and low FR-constant FR in the ventilator care of the neonates with acute respiratory failure. METHODS: For the neonates born in our hospital and treated with mechanical ventilation from March to August in 1997, two different ventilator strategies were employed randomly with flow control ventilator. In the high-FR group, the FR was fixed at 10 L/ min and the PL was adjusted according to the arterial blood gas analysis (ABGA) results. In the low-FR group, the FR was adjusted to 10 mL/kg of tidal volume. Sixty neonates were enrolled, 32 in high-FR and 28 in low-FR group. Ventilatory indices and clinical outcomes were statistically cornpared in the two groups. RESULTS: Perinatal factors were not different in the two groups. Initial ventilator settings, ABGA results and ventilatory indices were not different. The tidal volume, fraction of inspired oxygen, peak inspired pressure and oxygenation index were higher and dynamic compliance was lower in the high-FR group compared to the low-FR group after 3 to 72 hours of ventilator care. In clinical outcomes, incidences of pulmonary interstitial emphysema, pneumothorax and chronic lung disease were significantly lower in the low-FR group. CONCLUSION: Low-FR with constant FR strategy resulted in better clinical outcomes in the ventilator care of neonates. We conclude that constant FR strategy prevents damage of the better compliant lung units and decreases the incidence of acute and chronic complications of ventilator care.

The distal tibial physes begins its closure about 18 months prior to complete cessation of the tibial growth, closing first in its midportion, then medially, and finally, laterally. So the patterns of the ankle fracture during this period would be different from those of the adult or the children before this period. During the six year period from 1983 to 1988 at the department of orthopedic surgery, college of medi-cine, Hallym University, we found and analysed 54 adolescent patients with the ankle fracture which developed before the closure of the distal tibial growth plate, which were followed up more than 1 year. The results were as follows 1. During the 6 year period of this study, the adolescent ankle fracture comprise 4.4% (54 cases) of all the ankle fractures(1158 cases). Injury occurred more often in male than in female(44 versus 10). The mean age was 13.7 years. 2. The most common cause of injury was traffic accident being in 26 cases(48.1%), the next was slip down accident in 11 cases, and the third was sports activity in 10 cases. 3. The incidence of the adoescent ankle fractures using the Salter-Harris classification revealed 20 (37%) type II, 7 (13%) type III, 5 (9.3%) type IV, and 4 (7.4%) type I and that using the Dias and Tachdjian classification revealed 14 (25.9%) Supination-Inversion, 10 (18.5%) Supination-External rotation, 7 (12.7%) Pronation-Eversion-External rotation, and 1 (1.9%) no adjustable fracture. There were 9 (16.7%) Tillaux and 9 (16.7%) triplane fractures, which were belonged to both classifications 4. The treatments performed were closed reduction and cast immobilization for 28 cases (51.9 %), open reduction and internal fixation for 20 cases (37%), and closed reduction and percutaneous pinning for 6 cases. 5. There were complications experienced in 9 cases, which were 3 premature epiphyseal closure, 3 joint surface incongruity, 2 angular deformity, and 1 leg shortening. 6. For the prevention of the complication, the treatment of the adolecsent ankle fracture should be treated like as adult fracture.

OBJECTIVE: To report one case of cubital tunnel syndrome due to repetitive work METHOD: The authors examined a worker who complained of severe muscle atrophy between the right thumb and index finger, claw deformity and numbness of the 5th finger. We evaluated him with physical examination, neurophysiologic studies (nerve conduction study, NCV; electromygraphy, EMG), plain Xray and magnetic resonance image(MRI) at the right elbow. We also investigated his occupational history, and analyzed his work motions, using rapid upper limb assessment (RULA) of the work cycle at his previous work site. RESULT: The patient had been a ship welder for 17 years, followed by 6 years of dismantling boxes and loading/unloading materials. The latter job required inappropriate elbow posture such as repetitive flexion and extension. The NCV study revealed slow conduction velocity of the right ulnar motor and sensory nerve, decreased action potential of the right hand intrinsic muscles and flexor carpi ulnaris. The simple X-ray film showed normal finding, but MRI showed a finding compatible with cubital tunnel syndrome combined with enlargement of the right ulnar nerve at right elbow, 0.6cm intraarticular loose body and medial aspect of the medial epicondyle of the right distal humerus. CONCLUSION: We confirmed the diagnosis of cubital tunnel syndrome that was related to his packing job which had demanded repetitive flexion and extension of elbow joint. At the time of writing, surgery was being considered as appropriate treatment.

Hemoglobin(Hb), zinc protoporphyrin(ZPP) and blood lead(PbB) levels were determined for 1,851 blood samples collected from healthy urban population to establish reliable baselines for Hb, ZPP and PbB levels by age and sex. ZPP values were analyzed with a Hmatofluorometer and PbB determinations were concurrently carried out using flameless atomic absorption spectrophotometry. The blood sampling period was about 6 months from May, 1991 and the summarized results were as follows; 1. The mean value of Hb in male female were 14.55+/-1.81 g/dl and 12.61+/-1.81 g/dl respectively and there was statistically significant difference(p<0.05). 2. The mean value of ZPP in pre-schoolchildren was 37.49+/-13.31 microgram/dl for male, 35.77+/-11.85 microgram/dl for female and that of ZPP in after 7 years groups was 31.91+/-8.23 microgram/dl for male, 30.11+/-9.11 microgram/dl for female and there was statistically significant difference(p<0.05). 3. The mean value of PbB in pre-schoolchildren was 25.10+/-5.21 microgram/dl for male, 24.45+/-4.18 microgram/dl for female and that of PbB in after 7 years groups was 24.28+/-3.00 microgram/dl for male, 21.99+/-5.05 microgram/dl for female and there was statistically significant difference(p<0.05).

Wilms' tumor is one of the most common primary malignant tumors of the kidney during infancy and childhood and is known to be originated from the primitive cells of metanephric blastema. It presents difficulties when encountered in deciding the presence of anaplasia or in differentiating it from other renal tumors of childhood with different biologic behavior because of its diverse histologic patterns and varying degrees of differentiation. Evaluation of clinical and histopathologic features in terms of prognostication was done of 32 cases of Wilms' tumor which were surgically resected and diagnosed in the period from January 1979 through June 1992. Immunohistochemical reaction for cytokeratin, vimentin, actin and desmin was also analysed on all cases of Wilms' tumor in conjunction with clear cell sarcoma of the kidney(CCSK), malignant rhabdoid tumor of the kidney(MRTK) and congenital mesoblastic nephroma(CMN) to assess the validity of immunohistochemistry in differentiating Wilms' tumor from these renal tumors. Twenty four(75%) cases were diagnosed before the age of 5 and 40.7% were under 2 years old. Mixed type was most common(62.5%), followed by epithelial, blastemal and stromal predominant type in descending order of frequency. Anaplasia was observed in 3 cases(9.4%), two of which were epithelial predominant type and one blastemal predominant type. Treatment modality and presence of anaplasia were significantly correlated with 5 year survival rate of patients. Immunohistochemical stain revealed that all epithelial component of Wilms' tumor were positive for cytokeratin and 56.3% of Wilms' tumor had blastemal component which were positive for both cytokeratin and vimentin. Twenty cases(62.5%) of Wilms' tumor had blastemal component which were positive for cytokeratin with a proportion of more than 5% of reactive cells. Stromal component of Wilms' tumor generally did not show differentiation into the specialized type of tissue and all revealed positive reactions for vimentin among which some revealed positive reactions for actin. Only 3 out of 6 cases with rhabdomyoblastic differentiation were positive for desmin. CCSK, MRTK and CMN which have different biologic behavior and treatment modality compared to Wilm's tumor showed positivity only for vimentin and/or actin. In summary, treatment modality and presence of anaplasia are significantly correlated with patients' survival and the immunohistochemical stain for cytokeratin is very helpful in confirming the presence of blastemal component and useful in the differential diagnosis of Wilms' tumor from other kinds of pediatric renal tumors.
