From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

OBJECTIVE: We previously described that Diva is highly expressed in matured metaphase II (MII) oocytes compared to immature germinal vesicle (GV) oocytes in mouse.1 We report here that the expression of Diva transcript as well as protein is oocyte-specific. To elucidate its physiological role in oocyte, the binding partner(s) of Diva has been identified by using immunoprecipitation (IP) followed by Mass Spectrometry. METHODS: NIH/3T3 cells were transiently transfected for 24 h with either empty vector for control or FLAG-tagged mouse Diva construct, and IP was performed with anti-FLAG antibody. The immuno-isolated complexes were resolved by SDS-PAGE on a 12% gel followed by Coomassie Blue staining. For in-gel digestion, 15 bands of interest were excised manually and digested with trypsin. All mass spectra were acquired at a positive reflector mode by a 4700 Proteomics Analyzer (Applied Biosystems, Framingham, MA). Proteins were identified by searching the NCBI nonredundant database using MASCOT Peptide Mass Fingerprint software (Matrixscience, London). RESULTS: Diva-associated complexes were formed in FLAG-tagged mouse Diva-overexpressed NIH/3T3 cells via IP using anti-FLAG-conjugated beads. Among the excised 15 bands, actin and actin-binding proteins such as tropomyosin, tropomodulin 3, and alpha-actinin were identified. Binding between Diva and actin or tropomyosin was confirmed by IP followed by Western blot analysis. Both bindings were also detected endogenously in mouse ovaries, indicating that Diva works with actin and tropomyosin. CONCLUSIONS: This is the first report that immuno-isolated Diva-associated complexes are related to actin filament of the cytoskeletal system. When we consider the association of Diva with actin and tropomyosin, oocyte-specific Diva may play a role in modulating the cytoskeletal system during oocyte maturation.

BACKGROUND: Thromboembolism is the major complication in patients with the insertion of cardiac prosthetic valves. The purpose of this study is evaluate the risk factors about the formation of left atrial thrombi after cardiac valve replacement. METHOD: Transesophageal(TEE) and transthoracic echocardiography(TTE) were done to evaluate postoperative cardiac condition in 98 patients with cardiac prosthetic valves from Jan. 1991 to Oct 1991. Several clinical and echocardiographic parameters were analyzied to evaluate the relationship with the formation of left atrial thrombi. RESULT: In univariate analysis, important factors related to the formation of left atrial thrombi are type of operation (p=0.027), postoperative left ventricular function(p=0.003), preoperative(p=0.037) and postoperative systolic ventricular size(p=0.024). However, in multivariate analysis postoperative left ventricular size(p=0.017), presence of previous thrombi(p=0.014), preoperative left atrial size(p=0.014) and postoperative left atrial size(p=0.014) are significant factors. CONCLUSION: Patients with high risk and low risk for the formation of left atrial thrombi after valve replacement can be identified by readily available clinical and echocardiographic variables.

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality. It is well known that androgen and sex hormone-binding globulin(SHBG) in women were associated with risk factors for cardiovascular disease such as obesity, central fat accumulation and atherogenic lipid profile. High resolution B-mode ultrasonography can visualize directly both luminal and vessel wall characteristics, and ultrasonic measurement of carotid intima-medial thickness(IMT) can be used to investigate the atherosclerosis of coronary, cerebral and peripheral arteries. The aim of this study was to evaluate the relationship between the serum dehydroepiandrosterone sulfate(DHEA-S) and SHBG, and body fat distribution pattern, cardiovascular risk factor and carotid atherosclerosis in women. METHODS: Blood pressure, fasting serum glucose, insulin, lipid profile, SHBG and DHEA-S were measured. Body fat distribution pattern was assessed by waist to hip ratio, waist to thigh ratio and subscapular to triceps skin fold thickness ratio, faf mass measured by bioelectric impedance analyzer, subcutaneous fat area, visceral fat area, and visceral to subcutaneous fat area ratio(VSR) at the level of umbilicus using the computed tomography. The IMT of the carotid artery was measured by high resolution B mode ultrasound as a marker of atherosclerosis. RESULTS: 1) There was no significant difference of age-adjusted values of carotid IMT among subjects with NGT(0.426+/-0.09mm), IGT(0.46+/-10.09mm) and NIDDM(0.453+/-0.11mm). 2) In postrnenopausal women, carotid IMT was greater(0.484+/-0.11mm, p=0.05) than premenopausal women(0.426+/-0.08mm), but it was not significant after age adjustment. Serum SHBG and DHEA-S levels in postmenopausal women were significantly lower(p<0.05) than premenopausal women, but they were not significant after age adjustment. 3) Carotid IMT was significantly correlated with age(r=0.37, p<0.01), fasting serum glucose (r=0.32, p<0.01), total cholesterol(r= 0.25, p<0.05), LDL-cholesterol(r=0.26, p<0.05), visceral fat area(r=0.35, p<0.01) and VSR(r=0.31, p<0.05). 4) By the stepwise multiple regression analysis, carotid IMT was positively and significantly associated with age(p<0.01) and serum DHEA-S concentration(p<0.05) in dent of age, body mass index, waist to hip ratio, fasting serum glucose. CONCLUSION: Carotid IMT was associated with age and serum DHEA-S concentration in women without cardiovascular disease. Therefore, serum DHEA-S may be one of risk factors for cardiovascular disease in women. However, we could not conclude its cause-result relationship because of cross sectional nature of our study, and prospective study will be needed.

PURPOSE: The purpose of this study was to test the reliability and validity of an instrument that measures spiritual needs of families of terminal cancer patients. METHODS: This methodological study was processed as follows: 1) The preliminary 26 items were developed based a conceptual framework of spiritual needs of families of patients with cancer. 2) The content was validated by an expert panel (Three nursing professors and five hospice nursing specialists). 3) The instrument was validated by a survey (n=111). 4) Twenty-six items were selected and used for the final version of the scale. RESULTS: Three factors were extracted through factor analysis: ‘relationship with God/Acceptance of dying’, ‘recovery of relationship/hope and peace’, and ‘meaning and purpose of life’. These factors explained 61.088% of the total variance. Cronbach's alpha and Guttman split-half coefficient of the 26 items were 0.944 and 0.826 respectively. CONCLUSION: This scale was identified as a valid and reliable tool. Therefore, the scale is useful in assessing spiritual needs of families of terminal cancer patients in the field of hospice and palliative care.

6.Comparison of the Spiritual Needs of Terminal Cancer Patients and Their Primary Family Caregivers
Korean Journal of Hospice and Palliative Care 2020;23(2):55-70
Purpose:
This study was conducted to examine differences in Spiritual Interests Related to Illness Tool (SpIRIT) scores and the degree of spiritual needs (SNs) between patients with terminal cancer and their primary family caregivers and to compare spiritual needs between them.
Methods:
The study participants were inpatients with terminal cancer and their primary family caregivers at 40 national hospice centers. The final analysis included 120 SpIRIT surveys from patients and 115 from family members, and 99 SNs questionnaires from patients and 111 from family members. Data analysis was conducted using descriptive statistics, the t-test, one-way analysis of variance, and Pearson correlation coefficients.
Results:
There were no significant between-group differences in SpIRIT scores or SNs. The SpIRIT sub-dimensions that ranked high for both patients and primary family caregivers were “maintaining positive perspective”, “loving others”, and “finding meaning”. The SNs sub-dimensions were ranked identically in both groups, in the order of “love and connection”, “hope and peace”, “meaning and purpose”, respectively. In both groups, the recognition of the importance of spiritual matters and religion were major factors influencing SpIRIT scores and SNs.
Conclusion
The SpIRIT scores and degree of SNs of patients with terminal cancer and their primary family caregivers were found to be very closely related, and the needs for coherence and meaning were greater than religious needs. When providing spiritual care for patients with terminal illness, family members should also be considered, and their prioritization of spiritual needs and the importance of spiritual matters and religion shall be taken into account.

Purpose:
This study aimed to examine the differences in COVID-19 work-related characteristics, workload, anxiety, stress, and burnout between nurses working in the COVID-19 designated units and those in the general units caring for both COVID-19 and non-COVID-19 patients and to identify factors related to burnout in these two nurse groups.
Methods:
The study was conducted using data from 192 nurses in the COVID-19 designated units and 340 nurses in the general units from two general hospitals. The data were collected using self-report, structured questionnaires.Independent t-test, chi-squared test, and logistic regression analysis were performed.
Results:
There were no significant differences observed in workload and burnout between the two groups. For nurses in the general units, workload, stress, adequacy of the number of patients assigned, and the experience of temporary, floating staff were significant factors associated with burnout, while only clinical experience in the current unit was a significant factor among those in the COVID-19 units.
Conclusion
Findings indicate significant differences in factors related to burnout between the two nurse groups. Thus, substantial support and strategies tailored to the working environments of each nursing unit are required to prevent burnout among nurses caring for COVID-19 patients.

PURPOSE:
To evaluate Metal Artifact Reduction for Orthopedic Implants (O-MAR, Philips Healthcare) technique compared with standard filtered back projection (SFBP) technique on post-operative hip CT regarding image noise reduction and detection of post-operative complications.
MATERIALS AND METHODS:
Fifty-six hip CT scans after hip replacement with SFBP technique and O-MAR application were retrospectively reviewed. Region of interests (ROIs) were drawn at levels wherein acetabular cup and femoral head were largest at anterior and posterior acetabula, gluteus maximus muscle, subcutaneous fat adjacent to gluteus maximus muscle, and in area adjacent to prosthesis stem wherein lesser trochanter is largest. Hounsfield units (HU) were measured to evaluate artifact quantitatively; mean and standard deviations (SDs) calculated and compared. Periprosthetic complications were evaluated, and visibility rated between two reconstruction techniques; 1-SFBP better, 2–SFBP same as O-MAR, 3–O-MAR better.
RESULTS:
Average HU was significantly lower in O-MAR at posterior acetabulum, gluteus maximus muscle, and subcutaneous fat (p < 0.05). SD for HU was significantly lower in O-MAR at all ROIs (p < 0.05). Mean visibility of periprosthetic complications was 2.0, so equivalent.
CONCLUSION
Reconstruction with O-MAR technique in post-operative hip CT scans after hip replacement yielded statistically significant decrease in image noise. However, visibility of periprosthetic complications was not impacted by reconstruction technique.

Herpes simplex esophagitis can occur in those with normal immune function, but is more often seen in those who are immunocompromised. In one series, 5 percent of post-kidney transplant recipients had herpes esophagitis. We experienced a case of herpes simplex esophagitis, following renal transplantation in a 9 year old male. He complained of epigastric pain, nausea and blood-tinged vomiting. Endoscopic examination showed volcano ulcer, mucosal friability and multiple confluent ulcers covered by whitish exudates on elevated margin in the middle and lower esophagus. Microscopic findings revealed multinucleated giant cells, margination of chromatin, intense nonspecific inflammation and strong positive for herpes simplex virus immunohistochemical staining. Esophageal lesions and symptoms improved after acyclovir therapy.
