Background: Few studies have investigated unspecified or idiopathic pain associated with COIVD-19. This study aimed to provide the incidence rates of unspecified pain and idiopathic pain in patients with COVID-19 for 90 days after COVID-19 diagnosis. Methods: A propensity score matched cohort was used, including all patients with COVID-19 in South Korea, and analyzed their electronic medical records. The control group consisted of those who had not had tests for COVID-19 at all. Unspecified pain diagnoses consisted of diagnoses related to pain included in the ICD-10 Chapter XVIII. Idiopathic pain disorders included fibromyalgia, temporomandibular joint disorders, headaches, chronic prostatitis, complex regional pain syndrome, atypical facial pain, irritable bowel syndrome, and interstitial cystitis. Results: After matching, the number of participants in each group was 7,911. For most unspecified pain, the incidences were higher in the COVID-19 group (11.7%; 95% confidence interval [CI], 11.0-12.5) than in the control group (6.5%; 95% CI, 6.0-7.1). For idiopathic pain, only the headaches had a significantly higher incidence in the COVID-19 group (6.6%; 95% CI, 6.1-7.2) than in the control group (3.7%; 95% CI, 3.3-4.1). However, using a different control group that included only patients who visited a hospital at least once for any reasons, the incidences of most unspecified and idiopathic pain were higher in the control group than in the COVID-19 group. Conclusions: Patients with COVID-19 might be at a higher risk of experiencing unspecified pain in the acute phase or after recovery compared with individuals who had not had tests for COVID-19.

Incidences of major feline viral diseases provide basic information for preventing viral disease in cats. Despite the growing interest in feline viral diseases, sero-surveillances have been lacking. In this study, we analyzed the diagnoses of feline viral diseases and conducted a sero surveillance of feline panleukopenia virus (FPV), feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), and feline infectious peritonitis virus (FIPV) in Korean cats. Of the 204 confirmed cases since 2015, the numbers of diagnoses for FPV, FIPV, FCV, feline influenza virus, and FHV-1 were 156, 32, 12, 3, and 1 case, respectively. In total, 200 sera, collected between 2019 and 2021, were screened for the presence of antibodies against FPV, 2 FCVs, FHV-1, and FIPV using a hemagglutination inhibition test and a virus-neutralizing assay (VNA). The overall seropositive rates in cats tested for FPV, the 2 FCVs, FHV-1, and FIPV were 92.5%. 42.0%, 37.0%, 52.0%, and 14.0%, respectively. A low correlation (r = 0.466) was detected between the VNA titers of 2 FCV strains. The highest incidence and seropositive rate of FPV reveal that FPV is circulating in Korean cats. The low r-value between 2 FCVs suggests that a new feline vaccine containing the 2 kinds of FCVs is required.

Formaldehyde use is associated with serious health risks, which can affect medical personnel and technicians. Therefore, we investigated the efficacy of an alternative fixative, with respect to two types of formalin fixatives, by hematoxylin and eosin (H&E) staining, periodic acid Schiff (PAS) staining, immunohistochemical (IHC) staining, and RNA extraction. For H&E staining, the circular nucleus was stained dark blue by the basic dye hematoxylin and the cytoplasm was stained red by the acid dye eosin in all three fixative samples. No difference was found in the Duksan General Science (DGS), Sigma-Aldrich, and Core-Fix fixative samples (Corebiotech) used to fix kidney tissue, after PAS staining. IHC staining showed that CD4 was significantly increased in the lippolysaccharide (LPS)-treated group compared to the control group (vehicle), confirming the changes in specific molecules. The quantity and quality of RNA from tissues fixed in the three types of fixatives were evaluated. The average concentration of RNA was 106 ng/µL and average purity at A 260/280 ratio was 1.7~2.0, regardless of fixative used. For quality of protein, glyceraldehyde 3-phosphate dehydrogenase (GAPDH) protein was confirmed by Western blotting. In conclusion, Core-Fix can be used as a fixative for pathological tissues, in histological and molecular diagnoses.

Purpose: This study was conducted to evaluate the record completeness of the nursing process in the Electronic Nursing Record(ENR) in a university hospital. Methods: We compared nursing statements documented in 2004 with those from the year 2007, given the fact that the ENR system had been utilized since 2004. The ENRs of 35 gastrectomy patients in each year were selected for evaluation. The selected data were 11,822 nursing statements in 2004 and 27,870 in 2007. Results: The number of nursing records which documented the whole nursing process completely was 4,010 (48.3%) in 2007, whereas 513 (5.9%) in 2004 (p<.001). The number of incomplete records in 2004 was 8,142 (94.1%), while 4,300 (51.7%) in 2007 (p<.001). The number of nursing diagnoses was 846 in 2004 and 4,313 in 2007, which increased in number more than 5 times. The most frequently used diagnoses were 'pain', 'risk for infection' and 'risk for ileus' in both years. Conclusion: There was a significant increase in the record completeness on nursing process in 2007 compared to the records in 2004. The reasons for this increase are attributed to nurse training for encouraging to complete recording and nursing record auditing.

목적: 미만성 간질성 폐질환은 공통의 임상 양상, 방사선 소견, 폐기능 장애 소견을 갖는, 무수히 많은 원인 질환들로 구성되어 있어 개흉폐생검 등의 조직학적 진단이 표준으로 받아들여지고 있지만 관혈적 진단 방법이라는 단점이 있다. 고해상도 전산화단층촬영은 해상력을 높이고 음영의 중첩 효과를 최소화함으로써 폐간질의 미세한 변화까지 관찰할 수 있게 하겨 미만성 간질성 폐질환의 진단에 매우 유용한 진단 방법이다. 저자들은 이런 고해상도 전산화단층촬영을 한 환자에서 개흉폐생검을 시행하여 진단 및 치료에 어느 정도의 추가 이익을 얻을 수 있었는지 알아보고자 하였다. 방법: 1988년 3월부터 1994년 7월까지 미만성 간질성 폐질환의 진단적 목적으로 개흉폐생검을 시행한 30예의 환자들을 대상으로 후향적으로 고해상도 전산화단층촬영의 진단과 개흉폐생검외 진단 결과를 비교하고 각 환자들의 치료 방침을 조사하였다. 결과: 고해상도 전산화단층촬영은 28예에서 시행되었는데 이 중 22예(78.6%)에서 특이적 진단이 가능하였고 22예 중 20예에서는 개흉폐생검에 의해 같은 진단으로 확진되었다. 나머지 2예 중 1예는 개흉폐생검 결과가 비특이적이었다. 개흉폐생검은 전체 30예 중 25예(83.3%)에서 특이적 진단을 하였다. 또한 고해상도 전산화단층촬영으로 특이 진단이 불가능하였다. 6예 중 5 예(83.3%)에서 특이적 진단을 하였다. 전체 30예 중 단지 2예에서만 치료 방침의 결정적인 변화가 있었다. 결론: 미만성 간질성 폐질환 환자에서 고해상도 전산화단층촬영이 특이적 진단을 강력히 시사하는 경우에 개흉폐생검의 펼요성 여부에 대해서는 재검토가 필요할 것으로 생각된다.

Purpose: This study was performed to investigate the clinical usefulness of teleradiology in general dental practice. Materials and Methods: Two hundred and seventy five cases were submitted for inquiry to the case presentation board of the website of The Korean Academy of Oral and Maxillofacial Radiology for a 5 year periods. The diagnosis results of those cases were analyzed according to the disease classification, the correlation with the patient's chief complaint, the necessity of additional examinations or treatments, the image modalities, and the number of dentists inquiring. Results: Differential diagnoses of normal anatomic structures were the most frequently submitted cases, covering 15.6% of all cases. Among 275 cases, 164 cases required no additional treatments or examinations. Panoramic radiographs were the most frequently submitted images, accounting for 248 inquiries. The 275 cases were submitted by 96 dentists. Fifty-two dentists wrote one inquiry, and 44 inquired 2 or more times. The average inquiry number of the latter group was 5.0 cases. Conclusion: A teleradiology system in general dental practice could be helpful in the differential diagnosis of common lesions and reduce unnecessary costs.
