Fungal infection has been observed with increasing frequency in recent years because the use of combinations of broad spectrum antibiotics, immunosuppressive agents, and antineoplastic agents is increasing and the survival rate of premature baby is increasing. We experienced a 3 month old male infant with anuria due to bilateral ureteropelvic fungus balls. He was born at 31 weeks gestation period and had been treated with broad spectrum antibiotics for 5 weeks after birth. We removed fungus balls surgically and made nephrostomy bilaterally. And then irrigation of amphotericn B through nephrostomy and systemic amphotercin B injection had performed for 3 weeks. Thereafter fungus balls completely disappeared.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

BACKGROUND: Unilateral lung hyperinflation develops in lungs with asymmetric compliance, which can lead to vital instability. The aim of this study was to investigate the respiratory dynamics and the effect of airway diameter on the distribution of tidal volume during mechanical ventilation in a lung model with asymmetric compliance. METHODS: Three groups of lung models were designed to simulate lungs with a symmetric and asymmetric compliance. The lung model was composed of two test lungs, lung1 and lung2. The static compliance of lung1 in C15, C60, and C120 groups was manipulated to be 15, 60, and 120 ml/cmH₂O, respectively. Meanwhile, the static compliance of lung2 was fixed at 60 ml/cmH₂O. Respiratory variables were measured above (proximal measurement) and below (distal measurement) the model trachea. The lung model was mechanically ventilated, and the airway internal diameter (ID) was changed from 3 to 8 mm in 1-mm increments. RESULTS: The mean ± standard deviation ratio of volumes distributed to each lung (VL1/VL2) in airway ID 3, 4, 5, 6, 7, and 8 were in order, 0.10 ± 0.05, 0.11 ± 0.03, 0.12 ± 0.02, 0.12 ± 0.02, 0.12 ± 0.02, and 0.12 ± 0.02 in the C15 group; 1.05 ± 0.16, 1.01 ± 0.09, 1.00 ± 0.07, 0.97 ± 0.09, 0.96 ± 0.06, and 0.97 ± 0.08 in the C60 group; and 1.46 ± 0.18, 3.06 ± 0.41, 3.72 ± 0.37, 3.78 ± 0.47, 3.77 ± 0.45, and 3.78 ± 0.60 in the C120 group. The positive end-expiratory pressure (PEEP) of lung1 was significantly increased at airway ID 3 mm (1.65 cmH₂O) in the C15 group; at ID 3, 4, and 5 mm (2.21, 1.06, and 0.95 cmH₂O) in the C60 group; and ID 3, 4, and 5 mm (2.92, 1.84, and 1.41 cmH₂O) in the C120 group, compared to ID 8 mm (P < 0.05). CONCLUSIONS: In the C15 and C120 groups, the tidal volume was unevenly distributed to both lungs in a positive relationship with lung compliance. In the C120 group, the uneven distribution of tidal volume was improved when the airway ID was equal to or less than 4 mm, but a significant increase of PEEP was observed.

Objectives: During the coronavirus disease 2019 (COVID-19) pandemic, the prevalence of anxiety and depression in the general population was higher than before the pandemic. Identifying subjects at high risk for mental disorders may be necessary for effective mental health intervention. This study examines the prevalence of anxiety, depression, and anger and the related factors in the general population living in Daegu City one year after the COVID-19 pandemic. Methods: This study collected data on sociodemographic variables, the need for mental health intervention, Generalized Anxiety Disorder Assessment, Patient Health Questionnaire-9, and State-Trait Anger Expression Inventory state anger from 1,000 subjects. This study performed independent samples t-test, one-way ANOVA, post hoc analysis, chi-square tests, and binary logistic regression analyses to examine the relationship between sociodemographic variables including the need for mental health intervention and depression, anxiety, and anger. Results: The prevalence rates of depression, anxiety, and anger were 22.4%, 31.3%, and 42.3%. The need for mental health intervention was associated with the prevalence of depression, anxiety, and anger (p<0.001). Additionally, the risk of depression, anxiety, and anger was higher in the group with the need for mental health intervention compared to those without the need (odds ratio [95% confidence interval]; anxiety, 3.270 [2.337–4.575], p<0.001; depression, 4.475 [3.284– 6.097], p<0.001; anger, 4.225 [3.121-5.718], p<0.001). Conclusions One year after the COVID-19 pandemic, the prevalence of anxiety, depression, and anger in the general population of Daegu City was high. The subject’s perceived need for mental health intervention is associated with the prevalence of anxiety, depression, and anger and helps identify subjects requiring additional mental health intervention.

The clinical value of the pre-(165 pts) and post-operative(149 pts) serum levels of carcinoembryogenic antigen(CEA) in 190 patients(pts) with colorectal cancer was investigated, who had a curative surgery and an abnormally elevated levels of CEA (> or=5 ng/ml) at Department of General Surgery, Chonbuk National University Hospital during 1989 to 1996. The results are as follows: 1) The preoperative positive rates of CEA level were 49(29.7%) of 165 patients, so preoperative CEA level measurement was no usefulness for screening test of colorectal cancer. The incidence of preoperatively elevated CEA levels in Dukes stages A, B, C, and D were 0, 28.6, 32.8 and 42.9% respectively, There was significant association between increased proportion of patients with preopertive serum CEA(> OR = 5 ng/ml) and the progressive stages of colorectal cancers(P<0.05). 2) There was no significant association between the frequency of abnormal CEA level and histologic differentiation of tumor. 3) The recurrence rate was 16.4% and 30.6% in patients with preoperative CEA < 5 ng/ml and > OR =5 ng/ml, respectively(p<0.05). 4) In patients with recurrence, the lymph node positive group(70.6%) was larger than the negative(29.4%)(p<0.05), and preoperative positive rate of CEA value was 44%. 5) The recurrence rate in Dukes stages A, Bl, B2, Cl, C2, and D were 0, 8.7, 12.7, 16.7, 32.3, and 90.0% respectively(p<0.01). 6) There was no significant association between the frequency of abnormal CEA level and location of tumor. 7) The recurrence rate was 12.3% and 65.7% in patients with postoperative CEA < 5 ng/ml and > OR = 5 ng/ml, respectively(p<0.01). 8) In patients with metastasis, postoperative positive rate of CEA level was 63%(p< 0.01).

STUDY DESIGN: Clinical and radiographic results of spine fracutre treated with pedicle screws and hooks were reviewed. OBJECTIVES: Evaluate the efficacy of tile pedicle screw and hook for thoracolumar bursting fracture. SUMMARY OF LITERATURE REVIEW: Despite of the mechanical advantage of the pedicle screw, the metal failure in short segment fusion has been reported. A biomechanical study showed additional laminar hook increased rotational strength. MATERIALS AND METHODS: Between 1994 and 1996, seventeen patients who had a Denis type B bursting fracture of the thoracolumbar spine were treated by posterior instrumentation with pedicle screws and laminar hooks and auterior interbody fusion after partial corpectomy. They have been followed for an average of 13.4 months. RESULTS: At last follow-up, radiographs showed successful fusion of the injured spinal segment in all patient. The subsidence of grafts which were used In anterior interbody fusion was an average of 0.76mm. There was a loss of 2.6 degrees on average in the correction of the kyphosis. No patients had screw breakage or loosening. CONCLUSIONS: We concluded that posterior fixation with screws and hooks, anterior decompression by partial corpectomy, and strut-grafting in patient who had a Denis type B bursting frafture of the thoracolumbar spine yielded good radiographic and functional results.
