BACKGROUND: Currently establishment of public pharmaceutical companies became an issue for securing stable supply of national essential drugs in order to respond appropriately to national public health crisis. Pharmacy students as future pharmacists need to be interested in drug related issues under the discussion in our society. This study aimed to investigate perceptions of pharmacy students on the national drug supply strategy through public pharmaceutical companies. METHODS: A 20-items questionnaire designed for this study was used. Pharmacy students nationwide were enrolled in July 2017. They responded to questions through on-line survey program. Data were analyzed descriptively. RESULTS: 160 students from 26 pharmacy schools participated. 5th and 6th grade students accounted for two-thirds, and one third aspired future jobs in pharmaceutical industry. Among responders, 71.3% was unaware of current national essential drugs, 52.5% did not know the Rare and Essential Drug Center, and 91.9% was unaware of the legislation on the supply and management of essential drugs. 82.5% favored the establishment of public pharmaceutical companies. 80.6% agreed that government should intervene in pharmaceutical market for ensuring drug accessibilities, 73.8% agreed that public pharmaceutical companies make possible to reach a goal of stable supply of pharmaceuticals, and 85.1% agreed that active compulsory license by public pharmaceutical companies is necessary. CONCLUSION: We found that pharmacy students recognized the need for governmental control to achieve social values of pharmaceuticals. More attention and participation of the pharmacy students as well as pharmacists in the process of national debate on public pharmaceutical companies are expected.

A hand-arm vibration syndrome, local vibration illness, occurs in some workers who use hand held vibration tools. It consists of white fingers, diffusely distributed finger neuropathy, pain in the hand and arm, and a small excess risk of osteoarthritis. This study is aimed to identify effective methods to confirm local vibration illness among various health exams, which are mentioned in worker's special health exam regulation. In addition, this study is aimed to quantitatively assess the daily vibration exposure level as a major determinant of vibration illness. The subjects, 46 vibration workers, were selected according to the results of the first special health exam about vibration hazards at shipbuilding industry in 1997. They all had experiences of work related blanching of fingers. Fifteen controls, who had no vibration exposure at all, were also recruited to compare their test results with the results of vibration workers. We adopted 1 subjective and 6 objective tests to evaluate the effectiveness and feasibility for confirming local vibration illness. These tests were history taking of subjective symptoms according to the Stockholm classification, checking blood pressure of finger, checking grasp power, checking finger skin temperature, nail-bed pressing test, vibration perceptional threshold test, and skin prick test for pain perception. Among these, checking skin temperature, nail-bed pressing test, and vibration perception test included cold water provocations. We also estimated some vibration exposure levels of hand held vibration tools by using previously published data from one automobile company. In conclusion, history taking of subjective symptoms according to the Stockholm classification, nail-bed pressing test, and vibration perceptional threshold test were discovered to be effective to diagnose local vibration illness. Furthermore, vibration perceptional threshold on right fingers showed a dose-response relationship to daily vibration exposure levels. The parameter beta was 0.0005(+/-0.0002), and statistically significant by REM (random effects model).

Although CNS involvement of paragonimiasis is not frequently encountered, it has been reported in 10-25% of clinical cases of all paragonimiasis. It causes various symptoms and signs including epilepsy, headache, hemiparesis, visual field defect or other neurologic deficits. Infestation usually occurs by ingestion of freshwater crabs or crayfish infected with Paragonimus metacercariae. We report three patients with chronic cerebral paragonimiasis, which were diagnosed by history, neurologic examination, radiological and serological evaluations, Two of them had history of ingestion of freshwater crabs or crayfish in childhood. Only one patient showed a positive enzyme-linked immunosorbent assay reaction for Paragonimus specific antibody in serum and CSF. Their clinical manifestations were seizure, headache, and visual field defect. In their plain skull X-rays, congregated round oval calcifications were recognized. Brain computed tomography of patients revealed pathognomonic findings of multiple, variable sized, round, calcified lesions surrounded by low density areas together with cortical atrophy in occipital, parietal, and temporal lobes.

Objective:
Biliary decompression through bile drainage is a key treatment for common bile duct obstruction with cholangitis. However, the effectiveness of early interventions has not been studied sufficiently in Korea. This study investigated the effectiveness of fast-track biliary decompression.
Methods:
A group of patients diagnosed with common bile duct obstruction with cholangitis between January 1, 2014, and December 31, 2019, was reviewed retrospectively. We divided them into two groups: before and after the implementation of fast-track biliary decompression. The following items were analyzed in the two groups: time to intervention, number of hospital days, length of stay in the emergency department, and intensive care unit (ICU) admission.
Results:
Between January 1, 2014, and December 31, 2019, 418 patients were admitted for common bile duct obstruction, and a total of 369 patients were included in this study. Of these, 168 patients visited the hospital prior to implementation of the treatment, and 201 patients visited after implementation. The time to intervention was 6.1 (4.2-11.0) hours in the fast-track group, which was about 9 hours shorter than the other group (P<0.001). There was no statistical difference in the number of hospital days, emergency department length of stay, and ICU admissions (P=0.535, P=0.034, P=0.322).
Conclusion
The time to intervention was shortened significantly in the fast-track group. However, we did not observe a significant improvement in patient prognosis. It may be possible that the procedure time may need to be shortened for a better prognosis. This should be investigated in future studies.

BACKGROUND: Endoventricular circular patch plasty (EVCPP)was introduced as an effective reconstructive procedure for ventricular aneurysm and diffuse dilated cardiomyopathy after myocardial infarction.We report the 4-year results of EVCPP in Seoul National University Hospital, the experiences of anesthesia and intensive care for EVCPP in patients with ischemic cardiomyopathy. METHODS: EVCPP has been performed on 31 patients (22 men and 9 women wit h a mean age of 62 years)during 4 years from March 1998 to March 2002.Six patients (19%)were NYHA cl ass II,24 pat i ent s were cl ass III,and 1 pat i ent was cl ass I V.Preoperative and postoperative left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV),ejection fraction (EF)were determined and compared.Transesoghageal echocardiograghy (TEE)was used to measure the distance between aortic annulus and ventricular aneurysm during EVCPP.Milrinone combined with beta -adrenergics was infused during separation from cardiopulmonary bypass (CPB) and in the intensive care unit. RESULTS: Three patients (10%)needed an intra-aortic balloon pump to wean from CPB and one patient (3%)died in the hospital.Out of 30 survivors,29 patients returned to NYHA class I or II and one patient to class III.Out of 30 patients who underwent echocardiographic study before and after EVCPP,EF increased from 34 +/-9%to 38 +/-10%,and LVEDV and LVESV decreased from 139 +/-43 ml to 94 +/-20 ml and from 90 +/-34 ml to 59 +/-17 ml,respectively. CONCLUSIONS: EVCPP is effective to exclude the akinetic left ventricular segment,thus improving left ventricular function and clinical status of patients with ischemic cardiomyopathy.However, studies concerning postoperative intensive care are warranted to reduce the postoperative complications and morbidity.

A slowly growing, non-chromogenic mycobacterial strain was isolated from sputum and bronchial lavage fluid samples of a patient presenting with productive cough, blood-tinged sputum, low-grade fever, and weakness. A positive acid-fast bacilli sputum smear result prompted the initiation of an anti-tuberculosis regimen. Multiplex real-time PCR showed a negative result for Mycobacterium tuberculosis complex and a positive result for nontuberculous mycobacteria. The DNA chip test confirmed this organism as a member of the genus Mycobacterium, but could not specify the species. Interestingly, the mycolic acid patterns obtained by HPLC nearly overlapped with those of M. simulans. The sequences of the Mycobacterium 16S rRNA gene and 16S-23S internal transcribed spacer region were unique and were found to have 100% similarity with those of M. riyadhense. After a review of the literature, we report this case as the first Korean case of M. riyadhense lung infection.

BACKGROUND: Examination of peripheral blood smear (PBS) is the gold standard for the diagnosis of malaria; however, its diagnostic utility will be dependent on the examiner's microscopic experience, the quality of the smear, and the degree of parasitemia. Therefore, it is essential to have available a rapid and simple test that is as sensitive and specific as PBS, at a small-middle range medical center, a health care center, and a military hospital in a malaria endemic area. METHODS: Malaria antigen and antibody tests were performed on 120 febrile patients who were requested for complete blood count (CBC) and PBS at two military hospitals from May 2004 to August 2005. RESULTS: Of the 45 patients who were diagnosed with malaria by examination of peripheral blood smears, 42 were positive on both malaria antigen and antibody tests, and 2 were positive on either antigen or antibody test. Only 1 patient was negative on the both test. Furthermore, all 75 patients with negative microscopic examinations also had negative malaria antigen and antibody tests. CONCLUSIONS: The results of this study show that a rapid differential diagnosis of malaria can be made by performing malaria antigen and antibody tests on febrile patients at hospitals in malaria endemic areas. Moreover, the test is simple and convenient enough to be performed without any special equipment or experience.

Purpose:
Trocar-site burns occurring during laparoscopic surgery have been reported in various cases, and several efforts to reduce them are underway. This study aimed to analyze the effect of capacitive coupling on trocar site by observing electrical and histological changes for electrical skin burn injury.
Methods:
To measure the electrical changes relating to capacitive coupling, the temperature, current, voltage, and impedance around the trocar were measured when an open circuit and a closed circuit were formed using insulation intact instruments and repeated after insulation failure. After the experiment, the tissue around the trocar was collected, and microscopic examination was performed.
Results:
When open circuits were formed with the intact insulation, the impedance was significantly reduced compared to the cases of closed circuits (142.0 Ω vs. 109.3 Ω, p = 0.040). When the power was 30 W and there was insulation failure, no significant difference was measured between the open circuit and the closed circuit (147.7 Ω vs. 130.7 Ω, p = 0.103). Collagen hyalinization, nuclear fragmentation, and coagulation necrosis suggesting burns were observed in the skin biopsy at the trocar insertion site.
Conclusion
This study demonstrated that even with a plastic trocar and electrosurgical instruments that have intact insulation, if an open circuit is formed, capacitive coupling increases, and trocar-site burn can occur. When using electrocautery, careful manipulation must be taken to avoid creating an open circuit to prevent capacitive coupling related to electrical skin burn.

Laboratory Medicine Online 2020;10(2):152-159
Background:
The Laboratory Medicine Foundation (LMF) checklists explain the accreditation requirements of the program and reflect quality standards like those of the Clinical Laboratory Standards Institute (CLSI) or quality system essentials (QSE) of the World Health Organization (WHO). In this study, we have analyzed how the LMF checklists correlate with the 12 QSE elements of the WHO.
Methods:
The LMF checklists for laboratory management (LM) (version 2019) were classified into the 12 specific QSE elements by five laboratory physicians. Each checklist item was classified into specific element if four or more participants agreed, and into overlapping elements when two or more of them agreed for two different items. Any changes in checklist items and chapter structuring of the checklist since 2009 were investigated.
Results:
The LM checklists consisted of 183 checklist items, including 20 (10.9%) classified into overlapping QSE elements. The QSE element with the highest number of items was the facilities and safety (62, 33.9%), followed by the personnel (22, 12.0%), and the process control (17, 9.3%). In contrast, QSE elements with the lowest number of items were the customer service (4, 2.2%) and process improvement (4, 2.2%). Items belonging to the customer service and the organization elements have increased since 2017.
Conclusions
The LMF checklists reflect current quality goals for clinical laboratories and play a leading role in the laboratory's quality improvement. The results of our study will be of help in potentiating the quality leader role of LMF checklists, and international harmonization of our laboratory accreditation program.
