This study was performed to observe the therapeutic effects of interferon-gamma(IFN-gamma) and gamma-globulin(gamma-globulin) in experimental Pneumocystis carinii pneumonia of immune suppressed mice. After 9 weeks, trimethoprim-sulfamethoxazole(TMP-SMZ; 10-50 mg/mouse/day), mouse IFN-gamma(5 x 10(4) units/mouse/day) and mouse gamma-globulin(20 mg/mouse/day) were administered to the mice for 3 weeks by the experimental group. The therapeutic efficacy was evaluated by body weights, histopathologic and electron microscopic findings of the lungs, and number of P. carinii cysts by Gomori's methenamine silver stain. Body weights of the mice were significantly increased in the group of combination therapy of TMP-SMZ with IFN-gamma or gamma-globulin, and in the group of TMP-SMZ treatment (p < 0.05), however, little effect was found in the group of gamma-globulin alone. Histopathologic findings of P. carinii pneumonia were much improved in the group of combination therapy of TMP-SMZ with IFN-gamma. Treatment with either TMP-SMZ or IFN-gamma significantly reduced the number of cysts in the P. carinii pneumonia, but gamma-globulin alone was ineffective. In electron microscopic findings of P. carinii pneumonia, the number of trophozoites and cysts were reduced by treatment with either TMP-SMZ or IFN-gamma, and most of the cysts were empty or containing one or two intracystic bodies. The present results suggested, that combination therapy of TMP-SMZ with IFN-gamma had synergistic effects in treatment of P. carinii pneumonia in experimental mice.

2.Comparison of Clinical Outcomes between Rebound Hyperthermia and Non-Rebound Hypertherma Groups in Postcardiac Arrest Syndrome Patients Undergoing Targeted Temperature Management
Journal of Korean Critical Care Nursing 2023;16(3):99-108
Purpose:
: This retrospective study aims to provide basic data for intervention to improve clinical outcomes and identify the characteristics of the rebound hyperthermia (RHG) and non-rebound hyperthermia (NRHG) groups by checking body temperature in patients with post-cardiac arrest syndrome.Method : The study involved 118 patients who completed target temperature management (TTM) in an acute-care unit. Data were analyzed for frequency, percentages, mean, standard deviation, median, and quartiles, and compared using the chi-squared test and Mann–Whitney U-test.
Results:
: Rebound hyperthermia (RH) was observed in 74 (62.7%) patients, predominantly male (69.5%), with an average age of 64.54 ± 15.98, and a body mass index of 23.22 ± 4.75kg/m2 (overweight). Hypertension (50%) was the most common co-morbidity, followed by diabetes and heart disease (33.1%). Neuron-specific enolase levels were higher in the NRHG 24, 48, and 72 hours after recovery of spontaneous circulation (p = .037, p< .001, p= .008). The APHCHE Ⅳ was also higher in the NRHG (p< .001). RH occurred 25.49 (7.28–52.96) hours after TTM completion, lasting for 2 (1–3) hours. Temperature reduction strategies included notifying doctors, administering antipyretics, and nursing intervention, with the latter being the most common at 94.6%. Half of the subjects in the RHG and 77.3% in the NRHG fell into cerebral performance categories 3, 4, and 5 (p= .003).
Conclusion
: RH is more likely a body mechanism related to CPR and TTM than a result of pathogenic infection. Therefore, we require an active intervention for hyperthermia, and a patient-specific nursing intervention protocol.

Group occupational health service programme started in 1990 is one of the measures to cope with limited human and financial resources in occupational health. The programme has expanded rapidly to include 52 institutions, private as well as public, all over the country. In spite of its potential impact on health of employees and practice of occupational health in small and medium sized industries, comprehensive evaluation in terms of quality has not been tried. This study has aims to develop the criteria to assess the quality of newly developed group occupational health service programme, and to investigate the quality of institutions, and finally to develop policies for the quality improvement. 1) Criteria development : By defining occupational health services, in particular for small and medium sized industries, as one of the primary health care, followings are included as core elements of qualitative occupational health programme ; accessibility, continuity, comprehensiveness, technical quality, intersectoral collaboration, emphasis on preventive services, community participation, and adequacy. Again each element is divided into five major components of national health system infrastructure developed by the World Health Organization ; development of health resources, organized arrangement of resources, delivery of health care, economic support, and management. In turn, each component is categorized into three aspects of quality assessment, structure, process and outcome. Expert panel selected several criteria for each category to evaluate the programme. Criteria were modified according to each group of interviewees, to produce two sets of questionnaire, one for chief operating officer and another for nurses in the institutions, and the chief operating officer and workers in the workplace. 2) Subject : Of all 52 institutions, 25 voluntarily participated in the survey. At individual institution, chief operating officer and practicing nurses were interviewed in depth. After intensive education for interviewees, every interview was performed with standardized guideline and questionnaire. The quality of the 'Group occupational health service programme' was found to be lower than expected. Especially In continuity, comprehensiveness, technical quality, community participation and adequacy, lower quality in structural aspect was commonly identified throughout all the institutions. Quality in terms of accessibility and continuity highly varied among institutions. To improve quality of the programme, more comprehensive and systematic programme such as accreditation has to be introduced. In addition, human resources, governmental fund and information systems for individual workers are to be developed. As a long range plan, integration of occupational health services into the national health systems and pooling of financial resources and planned allocation should be considered.

Congenital adrenal hyperplasia (CAH) during pregnancy is a rare condition. Only a few cases have been reported in the literature. CAH patients has lower pregnancy rate compared to normal women. A 27-year-old nulliparous woman, a diagnosed case of 21-hydroxylase deficient simple virilising form of classic CAH visited. She got pregnant spontaneously without any trial of assisted reproductive technology. At the age of 12, she underwent clitoral resection and vaginoplasty. She took dexamethasone or prednisolone after operation. She delivered healthy singleton female baby by cesarean section. Four years later, she delivered healthy singleton female baby by repeat cesarean section. Two female babies have shown normal external genitalia. Here, we report a case of successful pregnancy and delivery in a patient with CAH.

OBJECTIVE: Methicillin resistant Staphylococcus aureus (MRSA) is the most common cause of postoperative infection in instrumented fusion surgery. Although MRSA is well-known cause of nosocomial infection, emerging evidence supports that there could be MRSA infection from community. This study evaluated the nasal colonization rate of MRSA among healthy adults within the age range of spinal fusion surgery in Korea. METHODS: Nasal swabs were collected from 99 participants who visited health promotion center. A structured questionnaire regarding healthcare-associated MRSA risk factors was collected simultaneously. Staphylococcus aureus was confirmed by latex agglutination. The resistance to methicillin was identified by oxacillin screening test. RESULTS: Of the 99 participants, 12 (12.1%) had S. aureus isolates. The nasal carriage rate of methicillin susceptible S. aureus (MSSA) was 9 (9.1%). MRSA was identified in 3 participants (3.0%). CONCLUSION: Among the age range of possible spinal fusion surgery, nasal colonization study revealed substantial rate of preoperative MRSA carriers even in healthy adults. A postoperative MRSA infection should not be exclusively considered to be due to surgery-related contamination.

PURPOSE: We report a case of intravitreal bevacizumab injection for the treatment of choroidal neovascularization in morning glory syndrome. CASE SUMMARY: A 51-year-old male visited our hospital for a 1.5-year visual disturbance in his right eye. The patient's best-corrected visual acuity was 0.1 in the right eye. After fundus examination, we found characteristic findings of morning glory syndrome with submacular hemorrhage and serous retinal detachment in the right eye. Optical coherence tomography, fluorescein angiography and indocyanine green angiography were performed for evaluation. Retinoschisis, subretinal fluid, and choroidal neovascularization were detected, and thus bevacizumab was injected in the right eye. After intravitreal bevacizumab injection, retinoschisis was improved, and subretinal fluid was decreased. However, retinal pigment epithelial detachment was newly detected, and serous retinal detachment persisted. After 2 months, a second bevacizumab injection was performed. After these intravitreal bevacizumab injections at 1 and 2 months, visual acuity was 0.4 and 0.6, respectively. Visual acuity improved to 1.0 after 3 months. Visual acuity was maintained for at least 6 months with no relapse of choroidal neovascularization. CONCLUSIONS: The choroidal neovascularization in morning glory syndrome was effectively treated with intravitreal bevacizumab injections.

A 59-year-old female patient with rheumatoid arthritis showed hypokalemic metabolic alkalosis, normotensive hyperreninemic hyperaldosteronism and high urinary prostaglandin level. She was thought to have Bartter's syndrome. But, her kidney biopsy specimen showed chronic interstitial nephritis. She have used acetaminophen containing analgesics for recent three years. So we thought her disease was caused by drug. But, in this case, clinical manifestations are correspond with Bartter's syndrome and we have witnessed a successful respond to kalium replacement, angiotensin converting enzyme inhibitor, prostaglandin inhibitor and spironolactone administration.

It is known that there appear some nonspecific and delicate changes in neuropsychiatric aspect on the workers when they are exposed for a long period to low concentrated organic solvents in the work places. Therefore, it give rise to the necessity of developing a program for the health supervisor stationed in the work place to supervise these neurobehavioral health affection. In addition to the questionnaire posed to the workers exposed to organic solvents, the study team conducted NCTB(Neurobehavioral Core Test Battery) respectively on an exposed group and a non-exposed group to organic solvents. The study team compared the results and decided whether or not to apply the results to the evaluation program of health affection. The study team divided 132 workers in 6 car repairing factories and 2 textile printing factories into exposed group and non-exposed group, pairing them off into 66 research objects according to their age, sex, and job. Neurobehavioral test was conducted on 6 items, except the POMS test, of NCTB developed by the World Health 0rganization (WHO) . The study team conducted examinations of working environment on the exposed and non-exposed groups of each work place. The analysis of the collected materials for examinations were conducted with GC-MS. The concentration of the mix-ture in the air, relative to their respective threshold limit values (TLV) was calculated according to the formula of the ACGIH and the Korean threshold limits. The results indicated that for two of eight factories samples the recommended concentration limits for mixtures was exceeded. Of the six tests, the'digit span forward','digit span backward'and'digit symbol' produced conspicuous statistical differences between the two groups (p<0.1) as a result of compairing the test values by means of paired t-test. The results of respective analysis of the car repairing factories and textile printing factories revealed that the textile printing factories had greater differences between the exposed and the non-exposed than in the car repairing factories. It is presumably because the textile printing workers are continuously exposed to the organic solvents during working hours, whereas the car repairing workers are exposed only when they are doing painting works. The NCTB is assessed very useful in examining the neurobehavioral health affection under the exposure to organic solvents, and, therefore, the study team expects that the NCTB will play an important part in the course of developing a health program for the workers exposed to organic solvents.

PURPOSE: To assess the clinical outcomes in idiopathic epiretinal membrane (ERM) patients after vitrectomy and ERM removal with or without additional indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling. METHODS: The medical records of 43 patients with an idiopathic ERM that underwent vitrectomy and ERM removal between July 2007 and April 2010 were reviewed. The patients were divided into two groups: triamcinolone-assisted simple ERM peeling only (group A, n = 23) and triamcinolone-assisted ERM peeling followed by ICG staining and peeling of the remaining internal ILM (group B, n = 20). RESULTS: No difference was found between the two groups in terms of visual acuity, macular thickness, P1 amplitude or implicit time on multifocal-electroretinogram (mfERG) at six and 12 months postoperatively. In group B, ICG staining after ERM peeling demonstrated that the ILM had been removed together with the ERM in 12 eyes (60%), and all 12 eyes showed punctate retinal hemorrhages during ERM peeling. There was no recurrence of an ERM in either group. CONCLUSIONS: Additional procedures involving ICG staining and ILM peeling during ERM surgery do not appear to have an additive effect on the clinical outcomes in terms of visual acuity, retinal function based on mfERG, or recurrence rate.

Human hairs have been known to be easily contaminated with microorganisms. This study was performed in order to measure what bacterial species and how much microorganisms contaminate human hairs in specific place. Virgin human hairs were left at 6 positions in inside corner and beside window in a laboratory for 7 days. The number of viable bacterial cells, which were determined by most probable number method, contaminating the human hairs was measured at a maximum of 10(6)/g hair and a minimum of 10(3)/g hair in inside corner and maximum of 10(6)/g hair and a minimum of 10(3)/g hair beside window. The bacterial cells-contaminating human hairs were observed via fluorescence light microscopy after 4',6-diamino-2-phenylindole (DAPI) staining. The bacterial community contaminating human hairs was analyzed via the thermal gradient gel electrophoresis (TGGE) technique, based on the diversity of the 16S-rDNA variable region. In total, approximately 20 bacterial species were detected from 12 groups of hair samples. In this study, general experimental methods-fluorescence staining, TGGE and MPN-were combined to develop new method for observation and estimation of bacteria contaminating human hairs.
