BACKGROUND: Selective lumbar nerve root block (SNRB) is generally accepted as an effective treatment method for back pain with sciatica. However, it requires devices producing radioactive materials such as C-arm fluoroscopy. This study evaluated the usefulness of the longitudinal view of transverse process and needles for medial branch block as landmarks under ultrasonography. METHODS: We performed selective nerve root block for 96 nerve roots in 61 patients under the guidance of ultrasound. A curved probe was used to identify the facet joints and transverse processes. Identifying the lumbar nerve roots under the skin surface and ultrasound landmarks, the cephalad and caudal medial branch blocks were undertaken under the transverse view of sonogram first. A needle for nerve root block was inserted between the two transverse processes under longitudinal view, while estimating the depth with the needle for medial branch block. We then injected 1.0 mL of contrast medium and checked the distribution of the nerve root with C-arm fluoroscopy to evaluate the accuracy. The visual analog scale (VAS) was used to access the clinical results. RESULTS: Seven SNRBs were performed for the L2 nerve root, 15 for L3, 49 for L4, and 25 for L5, respectively. Eighty-six SNRBs (89.5%) showed successful positioning of the needles. We failed in the following cases: 1 case for the L2 nerve root; 2 for L3; 3 for L4; and 4 for L5. The failed needles were positioned at wrong leveled segments in 4 cases and inappropriate place in 6 cases. VAS was improved from 7.6 +/- 0.6 to 3.5 +/- 1.3 after the procedure. CONCLUSIONS: For SNRB in lumbar spine, the transverse processes under longitudinal view as the ultrasound landmark and the needles of medial branch block to the facet joint can be a promising guidance.

The incidence of pediatric-onset inflammatory bowel disease (IBD) is on the rise, accounting for up to 25% of IBD cases. Pediatric IBD often has extensive bowel involvement with aggressive and rapidly progressing behavior compared to adult IBD. Because IBD has a high morbidity rate and can have a lifelong impact, successful transition from pediatric to adult care is important to maintain the continuity of care. Furthermore, successful transition facilitates appropriate development and psychosocial well-being among patients, as well as comprehensive and harmonious healthcare delivery amongst stakeholders. However, there are various obstacles related to patients, family, providers, and organizations that interfere with successful transition. Successful transition requires a flexible and tailored plan that is made according to the patient's developmental abilities and situation. This plan should be established through periodic interviews with the patient and family and through close collaboration with other care providers. Through a stepwise approach to the transition process, patients' knowledge and self-management skills can be improved. After preparation for the transition is completed and the obstacles are overcome, patients can be gradually moved to adult care. Finally, successful transition can increase patients' adherence to therapy, maintain the appropriate health status, improve patients' self-management, and promote self-reliance among patients.

Internet addiction (IA) has become a widespread and problematic phenomenon as smart devices pervade society. Moreover, internet gaming disorder leads to increases in social expenditures for both individuals and nations alike. Although the prevention and treatment of IA are getting more important, the diagnosis of IA remains problematic. Understanding the neurobiological mechanism of behavioral addictions is essential for the development of specific and effective treatments. Although there are many databases related to other addictions, a database for IA has not been developed yet. In addition, bioinformatics databases, especially genetic databases, require a high level of security and should be designed based on medical information standards. In this respect, our study proposes the OAuth standard protocol for database access authorization. The proposed IA Bioinformatics (IABio) database system is based on internet user authentication, which is a guideline for medical information standards, and uses OAuth 2.0 for access control technology. This study designed and developed the system requirements and configuration. The OAuth 2.0 protocol is expected to establish the security of personal medical information and be applied to genomic research on IA.

This report summarizes the 2019 survey results of the external quality assessment (EQA) scheme for the Transfusion Medicine Program (TMP) in Korea. Proficiency testing materials were prepared at the Asan Medical Center for the biannual distribution to participating laboratories. The average accuracy rates and number of participants (in parenthesis) for ten survey items were as follows: ABO typing, 99.4%–99.9% (N=875); RhD typing, 99.8%–100% (N=864); crossmatching, 90.8%–99.6% (N=760); ABO subtyping, 98.2% and 100% (N=58); Rh CcEe antigen testing, both 100% (N=55); weak D test, 97.9%–100% (N=232); antibody screening, 99.7%– 100% (N=316); direct antiglobulin test (DAT) using a polyspecific reagent, 99.6%–100% (N=273); DAT using an immunoglobulin-G monospecific reagent, both 100.0% (N=67); DAT using a C3d monospecific reagent, 95.6%–98.5% (N=67); antibody identification, 87.9%–99.2% (N=132); and ABO Ab titration, 85.7%–100% (N=134). The number of participants showed an average increase of 14% across the ten survey items, with the ABO antibody titration showing the highest increase at 83.6%. While results were generally excellent, antibody identification and ABO antibody titration results showed room for improvement. The 2019 EQA scheme for TMP has contributed to the improvement and maintenance of the participating laboratories to the program.

A case of fungemia caused by Cyberlindera fabianii was reported in the September issue of Annals of Clinical Microbiology. The C. fabianii that causes rare invasive infection can easily be misidentified as Candida utilis by Vitek-2 YST ID (bioMerieux, USA) and as Candida pelliculosa by API kit (bioMerieux, USA) with high probability. Recently, we also experienced a case of fungemia caused by C. fabianii that was misidentified as C. pelliculosa using API 20C Aux (bioMerieux, USA). As molecular identification is becoming more widespread, cases of C. fabianii infection are expected to be more frequently identified.

Background: Various types of external breast tissue expanders have been found to be effective for aesthetic breast augmentation. However, their use has been limited when compared with implant-based breast augmentation due to the burdensome nature of their application. This article reports the possibility that external breast tissue expanders may be applied safely and effectively with higher pressure and shorter application time. Methods: The participants comprised patients who desired breast augmentation using the EVERA-RAPHA device between January 2020 and March 2020. A double-blinded prospective study was conducted on two groups of eight patients each, with either 60 mmHg or 100 mmHg of pressure applied. Standardized photographs were taken and blinded measurements of volume and circumference were made. The Mann-Whitney and paired t-tests were conducted. Results: Sixteen patients were evaluated after 1 month of treatment. The women in groups 1 and 2 (60 mmHg and 100 mmHg, respectively) used EVERA-RAPHA for 15.400± 0.704 and 15.300±0.477 minutes per day, respectively. The mean volume increases in groups 1 and 2 were 39.000±42.526 cc and 27.700±20.260 cc, respectively. No patients dropped out of the study. All patients reported that the device was tolerable. Mild bruising was found in 62.5% of the patients in group 2. Conclusions Breast augmentation using external tissue expanders can be a safe, effective, and practical option. Pressures of 60 mmHg or 100 mmHg can be safely applied for a shorter duration. Larger studies are needed to further confirm our findings.

OBJECTIVES: The purpose of this study was to quantitatively assess the degree of myasthenia gravis (MG) affecting mental health through the results of multiphasic military personality inventory in late adolescence. METHODS: We collected and analyzed the results of the military personality inventory for healthy controls and MG patients among the 19-year-old men who visited the Military Manpower Administration from February 2007 to January 2010. Military personality inventory invented for Korean military test has similar system to Minnesota multiphasic personality inventory. RESULTS: Among validity scales, each score of faking good, faking bad and infrequency subscales showed no difference between healthy control and MG groups, respectively (t=−0.51, p=0.607 ; t=0.11, p=0.913 ; t=1.41, p=0.158). Among neurosis scales, the score of somatization subscale was higher (t=2.29, p=0.023) in MG group. Among psychopath scales, the score of schizophrenia subscale was lower in MG group (t=−2.38, p=0.018). CONCLUSIONS According to MPI results, we can confirm that MG patients in late adolescence may be more concerned with their somatic symptoms than the control group, and that they may be more likely to abide by the regulation and be conventional in their behavior than the control group.
