We describe a case of hyperbaric oxygen therapy (HBOt) as an adjunct to treatment of a crush injury to the hand. A 34-year-old male paramedic was involved in a motor vehicle accident and admitted for diagnosis and surgical treatment. He sustained a crush injury to his right hand and presented with significant muscle damage, including multiple fractures and dislocations, an avulsion injury of the flexor tendons, and amputation of the distal phalanx of the little finger. He underwent reconstructive surgery and received HBOt over the following days. In the following 2 months, he lost the distal and middle phalanges of the little finger and recovered hand function. Posttraumatic compartment syndrome responds well to HBOt, which reduces edema and contributes to angiogenesis, as well as promoting the cascade of healing events. High-energy trauma causes massive cell destruction, and the blood supply is usually not sufficient to meet the oxygen demands of viable tissues. Hyperbaric oxygenation by diffusion through interstitial and cellular fluids increases tissue oxygenation to levels sufficient for the host's responses to injury to work and helps control the delayed inflammatory reaction. HBOt used as an adjunct to surgical treatment resulted in early healing and rehabilitation, accelerating functional recovery. The results suggest that adjunctive HBOt can be beneficial for the treatment of crush injuries of the hand, resulting in better functional outcomes and helping to avoid unnecessary amputations.

This study applied Data Envelopment Analysis to a set of Korean Public Corporation Medical Centers and Japanese Municipal Hospitals to compare their relative human resource efficiencies. Based on the data provided on the inputs and outputs, the analysis showed Japanese municipal hospitals were relatively efficient than Korean hospitals. The result of analysing BCC model shows 5 hospitals in Japan and 7 in Korea with an efficiency rating of less than 1 as considered relatively inefficient. For the inefficient hospitals the manner in which inefficient hospitals may be made efficient were indicated by the managerial strategies based on dual variables. A subsequent analysis of Wilcoxon rank-sum test revealed that the medical revenue per medical expense, labor cost per value added revenue were statistically significant between efficient and inefficient Korean hospitals and medical revenue per medical expense, labor cost per value added revenue, bed occupancy rate, average length of stay, rate of personnel expenses per medical revenue were statistically significant between efficient and inefficient Japanese hospitals.

Purpose: The purpose of the study is to suggest the main functions and implications of public hospitals to effectively respond to the future epidemic crisis based on analyzing the accessibility to designated Coronavirus Disease 2019 (COVID-19) medical institutions of Seoul and examining the main features of the quarantine of Seoul municipal hospitals. Method: To analyze the response and function of Seoul municipal hospitals, we reviewed the Infectious Disease Control and Prevention ACT, 258 articles of Seoul Metropolitan Government press releases from January to the end of April, 48 articles of Seoul Metropolitan Government's daily newsletters, 2019 Health Bureau Budget report. We also referred to internal data of Seoul Children's Hospital, Seoul Seobuk Hospital, and Seoul Eunpyeong Hospital during the same period. Besides, the accessibility to medical institutions was analyzed by using the COVID-19 data which was announced daily basis. Results: The accessibility of COVID-19 patients living in the Southeastern part of Seoul to a medical institutions was 16.2km on a distance basis, and it was the lowest accessibility among four regions of Seoul since it took about 40 minutes by car. On the other hand, patients living in the Northeast part had the highest accessibility, as the access to medical institutions was 10.7km and 27 minutes by car. Also, the main functions of the municipal hospital of Seoul against COVID-19 were to shift the public hospital function to COVID-19 patients only hospitals, to perform the epidemiological investigation by medical doctors, and to support the operation of self-isolation facilities, community treatment centers and triage rooms of community health centers. Conclusion: Through the experience of COVID-19, we suggested that the functions of public hospitals will be reorganized as the reinforcement of infectious disease treatment and mental health for quarantined patients, cooperation with private hospitals, supporting for strengthening community health capacity and preparation for another epidemic.

Liver cancer is one of leading digestive malignancies with high morbidity and mortality. There is an urgent need for the development of novel therapies for this deadly disease. It has been proven that asparagus polysaccharide, one of the most active derivates from the traditional medicine asparagus, possesses notable antitumor properties. However, little is known about the efficacy of asparagus polysaccharide as an adjuvant for liver cancer chemotherapy. Herein, we reported that asparagus polysaccharide and its embolic agent form, asparagus gum, significantly inhibited liver tumor growth with transcatheter arterial chemoembolization (TACE) therapy in an orthotopic hepatocellular carcinoma (HCC) tumor model, while significantly inhibiting angiogenesis and promoting tumor cell apoptosis. Moreover, asparagine gelatinous possessed immunomodulatory functions and showed little toxicity to the host. These results highlight the chemotherapeutic potential of asparagus polysaccharide and warrant a future focus on development as novel chemotherapeutic agent for liver cancer TACE therapy.

The aim of this study was to investigate the role of kinesin superfamily member 15 (KIF15) in nasopharyngeal carcinogenesis (NPC) and explore its underlying mechanisms. We employed various assays, including the CCK-8 assay, flow cytometry, the Transwell and scratch assay, Western blotting, and nude mice transplantation tumor, to investigate the impact of KIF15 on NPC. Our findings demonstrate that KIF15 plays a critical role in the proliferation, apoptosis, migration, and invasion of NPC cells. Furthermore, we discovered that silencing KIF15 inhibits cell proliferation, migration, and invasion while promoting apoptosis, and that KIF15's effect on NPC cell growth is mediated through the PI3K/AKT and P53 signaling pathways. Additionally, we showed that KIF15 promotes nasopharyngeal cancer cell growth in vivo. Our study sheds light on the significance of KIF15 in NPC by revealing that KIF15 knockdown inhibits NPC cell growth through the regulation of AKT-related signaling pathways. These findings suggest that KIF15 represents a promising therapeutic target for the prevention and treatment of NPC.

연구 배경 : 폐결핵은 아직도 노인들에게 있어서 높은 유병률을 보이며 심각한 임상문제로 남아 있다. 그러나 노인 폐결핵은 젊은 연령 군에 비해서 증상이 비전형적이고 약제에 대한 부작용이 많아서 조기 진단 및 치료가 어려운 경우가 많다. 본 연구는 노인 폐결핵의 진단 및 치료에 있어서의 임상 양상이 젊은 연령 군과 비교하여 차이가 있는지 알아보기 위해 시행되었다. 연구 방법 : 1991년 11월에서 1997년 1월까지 서울 시립 보라매병원에서 폐결핵으로 진단, 치료받은 65세 미만인 젊은 연령 군 125명과 65셰 이상인 노인 군 70명올 대상으로 의무기록을 후향적으로 분석하였다. 결 과 : 노인 폐결핵 환자들은 젊은 연령 군에 비하여 식욕 감소(12% vs 31.4%), 전신 쇠약감(20.0% vs 54.3%), 호흡곤란(21.6% vs. 37.1%), 의식 변화(0.8% vs. 15.7%) 등의 비전형적인 증상으로 내원한 경우가 유의하게 많았다. 반변에 젊은 연령인 군에서는 노인 군에 비하여 객혈(32.8% vs. 10.0%), 발열(58.4% vs. 35.7%)의 빈도가 높았다. 기저질환에 있어 노인 군은 젊은 연령 군에 비하여 심혈관 질환과 만성폐쇄성 폐질환의 빈도가 유의하게 높았다. 흉부 X-선 소견 상 폐결핵 병변의 위치는 양군간에 차이가 없었으나 병변의 모양은 노인 군에서 폐렴이나 폐암으로 오인되는 경우가 많았다(8.8% vs. 30.0 %, p<0.05). 양군 간에 객담 항산균 포말 및 배양 검사상 차이는 없었으며, 치료에 대한 반응이나 치료 중 이탈률에도 차이가 없었다. 노인 군에서 젊은 연령 군에 비하여 약제 부작용이 많았고(13.6% vs. 45.7%, p<0.05), 치료 도중 약제 변경도 노인 군에서 많았다(4.9% vs. 25.7%, p<0.05). 젊은 연령 군 125명 중 1명, 노인 군 70명 중 6명이 결핵으로 인해 사망하였다. 결 론 : 노인 폐결핵은 임상적, 방사선학적으로 비전형적인 소견을 보이는 경우가 있으므로 노인에서 폐결핵이 의심될 때는 즉시 객담 도말 및 배양 검사를 시행해야 한다. 노인 폐결핵 환자는 약재 부작용이 사망률도 높았으나 치료에 대한 반응은 대체로 좋고 반응도 빨랐다.

Objective: To determine whether pituitary adenomas can be diagnosed by identifying protein biomarkers in the serum. Methods: We compared serum proteins from 65 pituitary adenoma patients and 90 healthy donors using proteomic fingerprint technology combining magnetic beads with matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS). Results: A total of 42 M/Z peaks were identified as related to pituitary adenoma (P<0.01). A diagnostic model established based on three biomarkers (3382.0, 4601.9, 9191.2) showed that the sensitivity of diagnosing pituitary adenoma was 90.0% and the specificity was 88.3%. The model was further tested by blind analysis showing that the sensitivity was 88.0% and the specificity was 83.3%. Conclusions: These results suggest that proteomic fingerprint technology can be used to identify pituitary adenoma biomarkers and the model based on three biomarkers (3382.0, 4601.9, 9191.2) provides a powerful and reliable method for diagnosing pituitary adenoma.

Objective: To investigate bladder and intestinal function recovery and quality of sexual life after laparoscopic nerve-sparing radical hysterectomy (LNRH) for treatment of early invasive cervical carcinoma. Methods: Subjects included patients who underwent radical hysterectomy by laparotomy who were randomly assigned to 2 groups: 30 patients who underwent LNRH and 35 classical laparoscopic radical hysterectomy (LRH). We assessed the patients general clinical information, surgical characteristics, pathological findings, and adjuvant therapies. A urodynamic study was used to assess bladder function. Intestinal function recovery and quality of sexual life were evaluated by questionnaire. Results: No significant differences were found in age, surgery characteristics, pathological findings, adjuvant therapies, and main adverse effects between the 2 groups. The mean duration of the postoperative catheterization (DPC) in group LNRH was shorter than that in group LRH (P < 0.001). The maximum flow rate, maximum cystometric capacity, maximum detrusor pressure and urinary complications in group LNRH were better than those in group LRH. The quality of sexual life evaluated according to the female sexual function index (FSFI) was better in group LNRH than in those who underwent LRH. The intestinal function of patients in group LNRH also recovered better compared with patients in group LRH.
