  • 의료기관에서 사용되는 수액 모니터링 시스템은 원격으로 환자에게 투입된 수액량과 투여의 종료시점 정보를 제공하기 위해서 개발되었다. 수액 투입량을 측정하기 위해서는 수액 내부에서 외부로 나가는 정량을 무게로 혹은 유량을 측정센서로 측정할 수 있다. 여기에 적용되는 장치의 기준은 정확성, 경계성이다. 또한 소형으로 환자에게 수액 설치시 사용에 용이해야 한다. 의료기관에서는 측정값의 정확도가 높아야 하며, 경제적으로 저가의 장치를 요구하고 있다. 본 연구에서는 저가의 소형 무게 중심 로드셀 센서를 적용하였으며, 측정값의 정확도를 위해 자이로센서와 융합하여 외부 움직임에 의한 아트펙트를 줄이는 알고리즘을 적용하였다. 그 결과 측정의 오차를 줄일 수 있어 수액 모니터링 측정값의 정확도를 향상시키는 효과를 확인하였다.

  • Objective: To find that the patients who conducted home self-exercise in conjunction with intra-articular corticosteroid injection will have better improvement in subacromial subdeltoid (SASD) bursitis symptoms than those who received only an injection. Method: A prospective, nonrandomized, comparison study was conducted in outpatient rehabilitation clinic in a tertiary university hospital. Patients diagnosed with SASD bursitis with physical examination and ultrasound evaluation were included and received ultrasound guided injection (UGI). Patients were divided into two groups according to the compliance of self-exercise: UGI-exercise group and UGI only group. Visual analog scale (VAS) was checked before, at 3 weeks, 3 months, and 6 months after the UGI. A patient's global impression of change (PGIC) survey was made at 3 months after the UGI. Results: A total of 82 patients with SASD bursitis were included. At 3 weeks after the injection, the mean VAS for the UGI-exercise group was 2.6 ± 1.7 and for UGI only group was 1.9 ± 1.3 (p=0.030). At 3 months after the injection, the mean VAS for the UGI-exercise group was 4.0 ± 1.3 and for UGI only group was 5.4 ± 1.4 (p<0.001). Conclusion: We concluded that home-based self-exercise of the shoulder provides an additional benefit for pain alleviation possibly with prolonging the effect of injection in SASD bursitis.

  • Purpose: The purpose of this study is to demonstrate the usefulness of the high resolutional ultrasonographic features in patients with foreign body. Methods: From September 2007 to August 2009, we retrospectively reviewed high resolutional ultrasonogram using 5~12 MHz linear transducer of 13 patients presenting with inflammation after foreign body injection. They were referred for complications after foreign body injection. Injected foreign bodies were 4 silicone, 4 paraffin, 2 artecoll, and 3 unknown. We treated them with foreign body removal (7), foreign body removal and corrective plastic surgery (4), and conservative treatment with antibiotics and steroid injection (2). Results: High resolutional ultrasonography well demonstrated the existence of foreign body and it's overall size, location within the tissue layer, and vascularity. Comparison between preoperative and postoperative ultrasonographic findings was useful not only to evaluate the prognosis but also to plan the treatment. These ultrasonographic findings aided in precise assessment of the contour and location of the foreign body and led to an accurate surgery. We were able to acquire various information in order to set a detailed plan for the operation which in turn, led to a precise, successful surgery. After the treatment, complication did not occur in 12 patients, except 1 patient. But this patient was also treated after reoperation. Postoperative high resolutional ultrasonography shows almost foreign body removed and inflammation disappeared. Conclusion: Considering the usefulness of highresolution ultrasonography in foreign body injection, highresolution ultrasonography would be necessary for both the patient and the doctor. Preoperative and postoperative high resolutional ultrasonography is highly accurate, safe, inexpensive and easy. It can be a useful modality in foreign body after plastic surgery.

  • Objectives: Bruising is an important side effect of enoxaparin injection. Comfrey (Symphytum officinale) is used to treat different types of wounds, bone fractures, and bruising in traditional medicine in many countries for centuries. This study aimed to determine the effects of the Comfrey ointment on the bruise size and color following enoxaparin injection. Methods: This double-blind randomized clinical trial was conducted on 80 patients with acute coronary syndrome (ACS). The participants were randomly divided into two groups of 40, namely Comfrey and Placebo. Changes in bruise size and color in both groups were assessed daily before and after the intervention. Results: The Comfrey and Placebo groups were homogeneous in demographic and clinical variables. A downward trend was observed in the bruise size in both groups throughout the study. However, the bruise size was smaller in the Comfrey group than the Placebo group on day 2-5 of the intervention. Moreover, there was a significant difference in bruise color between the groups, with a shorter healing course in the Comfrey group. Conclusion: The Comfrey ointment accelerated the healing process of enoxaparin injection-induced bruising in patients with ACS. It is recommended as a safe and simple approach for these patients.

  • Prostaglandin E1(PGE1) is a potent vasodilator and is a useful drug for the treatment of occlusive peripheral vascular disease. It has been used systemically via intravenous route or regionally via intraarterial route. We tried intravenous regional administration of PGE1 for the treatment of a patient with occlusive arterial disease involving left fingers. During the 13th injection, the patient complained of severe pain at the injection site during the drug administration. Thereafter, the patient developed painful and severe swelling with blebs on his left hand. Systemic antibiotics were given together with stellate ganglion block of the affected left side. PGE1 was substituted to reserpine, which is subcutaneously injectable, for the second term treatment.

  • Allergen-specific immunotherapy (AIT) is presumed to modulate the natural course of allergic disease by inducing immune tolerance. However, conventional AITs, such as subcutaneous immunotherapy and sublingual immunotherapy, require long treatment durations and often provoke local or systemic hypersensitivity reactions. Therefore, only <5% of allergy patients receive AIT as second-line therapy. Novel administration routes, such as intralymphatic, intradermal and epicutaneous immunotherapies, and synthetic recombinant allergen preparations have been evaluated to overcome these limitations. We will review the updated views of diverse AIT methods, and discuss the limitations and opportunities of the AITs for the treatment of allergic diseases in humans.

  • Objectives The purpose of this study is to investigate the current acupuncture therapy of cerebral palsy. Methods We investigated the Chinese clinical papers which were published in the last 10 years(from 1999 to 2008). We found these papers from the oriental medical library in university and we also used the China National Knowledge Infrastructure(CNKI) through the internet and selected 32 papers for analyzing. Results Most papers were described the effect of acupuncture or acupoint-injection. This is more effective way to treat than the general rehabilitation treatment such as the physical therapy, the occupational therapy, and the speech therapy. Acupuncture or acupoint-injection has overall $80{\sim}100%$ of rehabilitation rate. The younger the children were, the longer the treatment period was, and the more successful in treatment. The acupuncture was often used with the general acupuncture and scalp acupuncture. Commonly used major acupuncture points were sishencong(四神聰), bohui(百會), zusanli(足三里), yundongqu(運動區), pinghengqu(平衡區), quchi(曲池), and sanyinjiao(三陰交). Commonly used main meridian pathways were bladder, governor vessel, gallbladder, large intestine, stomach, small intestine meridian. Head is the common site for acupuncture. The main acupoint-injection points were zusanli(足三里), dazhui(大椎), shenshu(腎兪), yamen(啞門), neiguan(內關), and fengchi(風池). For the injection, brain activator, ganglioside M1, cerebroprotein hydrolysate, cytidine diphosphate choline, Vit B1, Vit B12, the salviae root, the safflower were commonly used. Conclusions Acupuncture and acupoint-injection have been shown as an effective treatment on cerebral palsy. The acupuncture was used often the general acupuncture and scalp acupuncture all together. Commonly used main acupuncture points were sishencong, bohui, zusanli, yundongqu, pinghengqu, quchi, sanyinjiao.

  • Background: An epidural steroid injection (ESI) is usually used for the treatment of low back pain with radiculopathy. An ESI can be performed by two procedures: I) a lumbar or caudal epidural steroid injection and II) a transforaminal epidural steroid injection. Methods: Ninety-three patients, who had undergone transforaminal epidural steroid injection (Group II), and either a lumbar or caudal epidural steroid injection (Group I), were retrospectively studied. The authors assessed the pain, walking, standing improvement and side effects after each procedure, which were evaluated as being very good, good, fair or poor. Data were collected from the patients medical records and analyzed using the chi-squared test. P < 0.05 was considered significant. Results: There were no statistically significant differences in the pain, walking, standing improvement and side effects between the two groups. However, there was a statistically significant difference in the pain improvement following transforaminal epidural steroid injection in those not effectively responding to an initial lumbar or caudal epidural block in Group II. Conclusions: A transforaminal epidural steroid injection is a useful alternative to a lumbar or caudal epidural steroid injection for low back pain with radiculopathy.

  • The anti-tumorigenic effects of Toxoplasma gondii (RH) antigens were studied in a murine sarcoma-180 tumor model. To determine the anti-tumor effects, the reduction in tumor size and expression of CD31 (an angiogenesis marker in the tumor tissue) were examined after injection of BALB/c mice with T. gondii lysate antigen (TLA) or formalin-fixed, proliferation-inhibited, T. gondii tachyzoites. Tumors were successfully produced by an intradermal injection of sarcoma-180 cells with plain Matrigel in the mid-backs of mice. After injection with TLA or formalin-fixed T. gondii tachyzoites, the increase in tumor size and weight nearly stopped while tumor growth continued in control mice that were injected with PBS. CD31 expression in TLA-treated or formalin-fixed T. gondii-injected mice was lower than the control mice. Accordingly, the present study shows that the treatment of mice with formalin-fixed T. gondii or TLA in the murine sarcoma-180 tumor model results in a decrease of both tumor size and CD31 expression.
