2.Continuous Brain-derived Neurotrophic Factor (BDNF) Infusion After Methylprednisolone Treatment in Severe Spinal Cord Injury.
Journal of Korean Medical Science 2004;19(1):113-122
Although methylprednisolone (MP) is the standard of care in acute spinal cord injury (SCI), its functional outcome varies in clinical situation. Recent report demonstrated that MP depresses the expression of growth-promoting neurotrophic factors after acute SCI. The present study was designed to investigate whether continuous infusion of brain-derived neurotrophic factor (BDNF) after MP treatment promotes functional recovery in severe SCI. Contusion injury was produced at the T10 vertebral level of the spinal cord in adult rats. The rats received MP intravenously immediately after the injury and BDNF was infused intrathecally using an osmotic mini-pump for six weeks. Immunohistochemical methods were used to detect ED-1, Growth associated protein-43 (GAP-43), neurofilament (NF), and choline acethyl transferase (ChAT) levels. BDNF did not alter the effect of MP on hematogenous inflammatory cellular infiltration. MP treatment with BDNF infusion resulted in greater axonal survival and regeneration compared to MP treatment alone, as indicated by increases in NF and GAP-43 gene expression. Adjunctive BDNF infusion resulted in better locomotor test scores using the Basso-Beattie-Bresnahan (BBB) test. This study demonstrated that continuous infusion of BDNF after initial MP treatment improved functional recovery after severe spinal cord injury without dampening the acute effect of MP.

4.An Analysis of Trends in Reports on Alternative Medicine in General Dailies.
Journal of Korean Society of Medical Informatics 2005;11(4):353-360
OBJECTIVE: This study analyze the standpoint of newspapers toward alternative medicine. METHODS: Through the content analysis of the articles selected by Korean Integrated News Database System(KINDS). With news items about alternative medicine in nine general dailies for six years between 1997 and 2002, this study was conducted to grasp the trend of the reports and provide investigation data to the alternative medicine communication. RESULTS: As social concerns about health drastically increase, many types of health information and common senses in medicine are recently pouring out through various media. Newspapers and TV are competitively presenting items and programs about health every day. Now anyone can approach information and common senses in medicine with ease if he or she wants. The problem is that reports and programs about health pouring out through each medium contain a great amount of wrong information that can have a bad influence on national health. If wrong information is delivered to the people, or medical consumers, through the mass media, they can suffer from very serious side-effects and aftereffects. If patients or caregivers misled by false information on health commit an error in judgement, they can make their disease worse or miss the proper moment for treatment and consequently meet an irrevocable misfortune. For this reason, they must be careful in dealing with information on health. CONCLUSION: In consideration of results, many type of health information are expected to grow in the future. Therefore it is important for information providers to maintain a sound policy which is scientific and objective in order to protect information consumers.

6.A Review on the RF Coil Designs and Trends for Ultra High Field Magnetic Resonance Imaging
Daniel HERNANDEZ ; Kyoung-Nam KIM
Investigative Magnetic Resonance Imaging 2020;24(3):95-122
In this article, we evaluated the performance of radiofrequency (RF) coils in terms of the signal-to-noise ratio (S/N) and homogeneity of magnetic resonance images when used for ultrahigh-frequency (UHF) 7T magnetic resonance imaging (MRI). Highquality MRI can be obtained when these two basic requirements are met. However, because of the dielectric effect, 7T magnetic resonance imaging still produces essentially a non-uniform magnetic flux (|B1 |) density distribution. In general, heterogeneous and homogeneous RF coils may be designed using electromagnetic (EM) modeling. Heterogeneous coils, which are surface coils, are used in consideration of scalability in the |B1 | region with a high S/N as multichannel loop coils rather than selecting a single loop. Loop coils are considered state of the art for their simplicity yet effective |B1 |-field distribution and intensity. In addition, combining multiple loop coils allows phase arrays (PA). PA coils have gained great interest for use in receiving signals because of parallel imaging (PI) techniques, such as sensitivity encoding (SENSE) and generalized autocalibrating partial parallel acquisition (GRAPPA), which drastically reduce the acquisition time. With the introduction of a parallel transmit coil (pTx) system, a form of transceiver loop arrays has also been proposed. In this article, we discussed the applications and proposed designs of loop coils. RF homogeneous coils for volume imaging include Alderman-Grant resonators, birdcage coils, saddle coils, traveling wave coils, transmission line arrays, composite right-/left-handed arrays, and fusion coils. In this article, we also discussed the basic operation, design, and applications of these coils.

Purpose:
To evaluate the surgical outcomes of a modified normogram for bilateral lateral rectus recession in the surgical management of intermittent exotropia, with a focus on achieving small overcorrection.
Methods:
A retrospective medical chart review of 242 patients who underwent surgery for intermittent exotropia between October 2014 and June 2020 was performed. Our modified normogram reducing amount of recession targeted for small postoperative overcorrection within 5 prism diopters (PD). Patients were observed for at least 3 years. Esodeviation was denoted by negative numbers and positive values indicated exodeviation. A satisfactory outcome was defined as if distant angle of deviation ranged between ≤10 PD of exotropia and ≤5 PD of esotropia. Recurrence was defined as an exodeviation of >10 PD at distance. Overcorrection was defined as an esodeviation of >5 PD at distance.
Results:
The mean preoperative deviation angles were 29.32 ± 3.92 PD at distance and 29.88 ± 4.41 PD at near. At postoperative day 1, the mean deviation angles at distance and near were –6.22 ± 1.44 and –6.22 ± 1.49 PD, respectively. Overcorrection within 6 PD of esodeviation was seen in 168 patients (69.42%), undercorrection with exophoria was noted in 11 patients (4.55%), and overcorrection by more than 6 PD of esodeviation was seen in 63 patients (26.03%) at postoperative day 1. The long-term success rate at postoperative 3 years was 77.27% (187 of 242), with a recurrence rate of 19.83% (48 of 242) and an overcorrection rate of 2.89% (7 of 242). A positive correlation between the angle of deviation at postoperative day 1 and 3 years was observed (r = 0.22, p = 0.001). The final success rate at the final examination after a mean follow-up of 38.60 ± 7.99 months was 83.06%.
Conclusions
Our modified normogram for bilateral lateral rectus recession in intermittent exotropia surgery resulted in successful surgical outcomes with small overcorrection, reducing the risk of consecutive esotropia due to excessive overcorrection.

The expression of both constitutive and inducible forms of nitric oxide synthase (NOS) was investigated by immunohistochemical staining of formalin-fixed paraffin-embedded sections in normal and Listeria monocytogenes-infected brains of goats. In normal control goats, a small number of neurons showed immunoreactivity of both iNOS and nNOS, and the number of iNOS-positive neurons was higher than the number of nNOS-positive neurons. In natural listeriosis, listeria antigens were easily immunostained in the inflammatory cells of microabscesses. In this lesion, the immunoreactivity of iNOS in neurons was more intense than the control, but nNOS was not. In microabscesses, nNOS was weakly visualized in macrophages and neutrophils, while iNOS was expressed in macrophages, but not in neutrophils. These findings suggest that normal caprine brain cells, including neurons, constitutively express iNOS and nNOS, and the expressions of these molecules is increased in Listeria monocytogenes infections. Furthermore, inflammatory cells, including macrophages, expressing both nNOS and iNOS may play important roles in the pathogenesis of bacterial meningoencephalitis in goat.

Proton pump inhibitors (PPIs) were clinically introduced more than 25 years ago and have since proven to be invaluable, safe, and effective agents for the management of a variety of acid-related disorders. Although all members in this class act in a similar fashion, inhibiting active parietal cell acid secretion, there are slight differences among PPIs relating to their pharmacokinetic properties, metabolism, and Food and Drug Administration (FDA)-approved clinical indications. Nevertheless, each is effective in managing gastroesophageal reflux disease and uncomplicated or complicated peptic ulcer disease. Despite their overall efficacy, PPIs do have some limitations related to their short plasma half-lives and requirement for meal-associated dosing, which can lead to breakthrough symptoms in some individuals, especially at night. Longer-acting PPIs and technology to prolong conventional PPI activity have been developed to specifically address these limitations and may improve clinical outcomes.

Daniel H KIM ; Judith A MUROVIC ; David G KLINE
Journal of Korean Neurosurgical Society 2004;36(3):177-185
This paper reviews the mechanisms of brachial plexus injury which includes the traumatic: stretch/contusions with or without avulsion, gunshot wounds(GSWs) and lacerations and the nontraumatic from tumors and the various etiologies of thoracic outlet syndrome(TOS). Another type of brachial plexus injury is that of obstetrical birth injury. The paper also reviews the anatomy of the brachial plexus and operative approaches with the anterior approach used in the majority of cases. The posterior subscapular approach with resection of the first rib is occasionally used for tumor resection, GSWs of the lower roots and trunk and the majority of patients with TOS. Surgical techniques and their indications in brachial plexus surgery are presented including nerve action potential(NAP) recording, neurolysis, end-to-end suture anastomosis repair and graft repair including split-repair. The mechanisms of brachial plexus injury are individually reviewed and results for each type of repair of same from the Louisiana State University Health Sciences Center(LSUHSC) experience with 1, 019 patients between 1968-1998 are summarized. There were 509 (49%) stretch/contusion injuries, which was the majority lesion followed in number by brachial plexus GSWs (12%) and lacerations (7%). Nontraumatic brachial plexus injuries included tumors (16%) and TOS (16%). Obstetrical brachial plexus injury though not included with the 1, 019 patients presented in a paper by Kim and Kline et al (J Neurosurg 98: 1005-1016, 2003) are presented and the LSUHSC experience with these are included as well.
