Krabbe disease is a rare autosomal recessive disorder clinically characterized by retardation in motor development, prominent spasticity, seizures, and optic atrophy. Pathologically, there are many globoid cells in the white matter, in addition to the lack of myelin and the presence of severe gliosis. Hence Krabbe disease is known as globoid cell leukodystrophy. Biochemically, the primary enzymatic deficiency in Krabbe disease is galactocerebroside beta-galactosidase. Patients with Krabbe disease can be subdivided into the early-onset type and late-onset type, according to the onset of clinical manifestations. Most patients with early-onset type die before their second birthday. We describe a girl with Krabbe disease associated with uncontrolled seizures, which was confirmed with biochemical study and MRI. The clinical findings of this patient included hyperirritability, scissoring of the legs, flexion of arm, and clenching of the fists, and generalized tonic seizures. EEG showed hypsarrhythmia, and MRI demonstrated degenerative white matter changes in bilateral periventricular white matter, posterior rim of internal capsule, basal ganglia and brain stem on T2W1 and FLAIR image. The diagnosis was based on clinical features of progressive neurologic deterioration in conjunction with low galactocerebroside beta-galactosidase activity.

Methicillin-resistant coagulase-negative staphylococci (MRCNS) were isolated from the respiratory sites of chickens in 4 farms and slaughter house located in Chungnam provinces. Isolation of coagulase-negative staphylococci (CNS) was positive for 61 (26.6%) of the 229 chickens tested, and isolation of MRCNS was positive for 17 (27.9%) of the isolated CNS. A total of 17 MRCNS isolates were selected and subjected to identification. Of the 17 MRCNS isolates selected, 6 were identified as Staphylococcus cohnii, 2 as S. saprophyticus, 3 as S. simulans, 3 as S. lentus, 2 as S. carnosus, and 1 as S. xylosus. The MRCNS isolates were resistant to many beta-lactam antibiotics, and some isolates were also resistant to macrolide and aminoglycoside antibiotics. The mecA gene was detected in some isolates of each MRCNS strains. The mecA-positive isolates were classified into five staphylococcal cassette chromosome mec (SCCmec). SCCmec types I to IV were detected in isolates from chickens.

Purpose: Myotonic dystrophy, also known as dystrophia myotonica (DM), is an autosomal dominant disorder with 2 genetically distinct forms. DM type 1 (DM1) is the more common form and is caused by abnormal expansion of cytosine/thymine/guanine (CTG) repeats in the DM protein kinase (DMPK ) gene. Our study aimed to determine whether the age of onset is correlated with CTG repeat length in a population of pediatric patients with DM1. Methods: We retrospectively identified 30 pediatric patients with DM1 that underwent DMPK testing, of which the clinical data of 17 was sufficient. The cohort was divided into 2 subgroups based on the clinical phenotype (congenital-onset vs. late-onset) and number of CTG repeats (<1,000 vs. ${\geq}1,000$). Results: We found no significant difference between the age of onset and CTG repeat length in our pediatric patient population. Based on clinical subgrouping, we found that the congenital-onset subgroup was statistically different with respect to several variables, including prematurity, rate of admission to neonatal intensive care unit, need for respiratory support at birth, hypotonia, dysphagia, ventilator dependence, and functional status on last visit, compared to the late-onset subgroup. Based on genetic subgrouping, we found a single variable (poor feeding in neonate) that was significantly different in the large CTG subgroup than that in the small CTG subgroup. Conclusion: Clinical variables exhibiting statistically significant differences between the subgroups should be focused on prognosis and designing tailored management approaches for the patients; our findings will contribute to achieve this important goal for treating patients with DM1.

Objective : Spinal cord stimulation (SCS) is an effective treatment for chronic neuropathic pain. However, its clinical efficacy in regard to specific types of pain has not been well studied. The primary objective of this study was to retrospectively analyze the clinical outcomes of paddle-type SCS according to the type of neuropathic pain. Methods : Seventeen patients who underwent paddle-lead SCS at our hospital were examined. Clinical outcomes were evaluated pre- and postoperatively (3 months, 1 year, and last follow-up) using the Neuropathic Pain Symptom Inventory (NPSI). The NPSI categorizes pain as superficial, deep, paroxysmal, evoked, or dysesthesia and assess the duration of the pain (pain time score). Changes in NPSI scores were compared with change in Visual analogue scale (VAS) scores. Results : After SCS, the pain time score improved by 45% (independent t-test, p=0.0002) and the deep pain score improved by 58% (independent t-test, p=0.001). Improvements in the pain time score significantly correlated with improvements in the VAS score (r=0.667, p=0.003, Spearman correlation). Additionally, the morphine milligram equivalent value was markedly lower after vs. before surgery (~49 mg, pared t-test, p=0.002). No preoperative value was associated with clinical outcome. Conclusion : The NPSI is a useful tool for evaluating the therapeutic effects of SCS. Chronic use of a paddle-type spinal cord stimulation improved the deep pain and the pain time scores.

Background: This study evaluated the clinical and radiologic outcomes of onlay patch augmentation in rotator cuff repair for moderate-to-large tears in elderly patients. Methods: We reviewed 24 patients who underwent onlay augmentation with dermal allograft after arthroscopic rotator cuff repair from January 2017 to March 2020. Inclusion criteria were patients aged >65 years with tears >2.5 cm, who were followed for >12 months after surgery, and patients who could raise their arms above 90° preoperatively. American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, pain visual analog scale (VAS), and VAS for satisfaction were used as clinical outcomes. For the evaluation of cuff integrity, magnetic resonance imaging scans were performed every 3 months after surgery. The results were compared before and after surgery in all patients and between the retear and intact groups. Results: The average follow-up period was 16.38 months, and the mean age of patients was 71.05 years. All patients showed significant improvement in ASES score, Constant-Murley score, and pain VAS at the last evaluation. The average value of satisfaction VAS was 7.27/10. The retear rate was 25% (6/24) if Sugaya type 3 was categorized in the retear group, otherwise 16.7% (4/24), if Sugaya type 3 was categorized into the intact group. Irrespective of Sugaya type 3 being included in the retear group, there was no significant difference in outcome variables between the intact and retear groups during follow-up. Conclusions: In moderate-to-large rotator cuff tear in elderly patients, onlay patch augmentation improved clinical outcomes. Retear did not adversely affect clinical outcomes.

Objectives: The purpose of this study is to review the trend of chinese clinical studies of herbal treatment for infertility caused by Polycystic Ovary Syndrome (PCOS). Methods: We searched the clinical studies published from 1979 to 2013 through CAJ (Chinese Academic Journal) with keywords of "PCOS and 不孕" or "多囊卵 巢綜合證 and 不孕". We analyzed the intervention type of clinical studies. In addition, We researched randomized controlled trials (RCTs) published from 2009 to 2013, assessed the quality of RCTs using the Jadad Scale and reanalyzed the intervention type of RCTs. Results: One hundred and seventeen clinical studies were finally selected. Clinical studies of herbal treatment for infertility caused by PCOS increased remarkably after the 2000s in China. Combined herbal medicine and western medicine was used the most frequently. RCTs published from 2009 to 2013 were fifty. Average of Jadad score of RCTs was 1.2. Combined herbal medicine and western medicine was also the most frequently used as intervention in RCTs. Conclusions: Clinical studies on effect of combined herbal medicine and western medicine for infertility caused by PCOS were mostly published in China. But Quality of studies was generally low. Further research on effect of herbal treatment for infertility caused by PCOS is needed.

Purpose: This study aimed to determine a method to reduce stress in clinical practice by identifying how the empathy and self-regulation capacities of paramedic students influence their stress levels. Methods: Selected articles were statistically analyzed using SPSS 21.0. Data on 172 3rd-year and 4th-year paramedic students in Daejeon were used. The subject's general characteristics (sex, university education, the number of the medical training center, work type, satisfaction with college life, and satisfaction with their major) were analyzed according to empathy and self-regulation ability by t-test and ANOVA. Pearson's correlation coefficient was used for the correlation of empathy, self-regulation ability, and clinical practice stress. Hierarchical regression was used for factors influencing clinical practice. Results: Clinical practice stress levels were significantly different between general characteristics of sex (t=3.002, p=0.003), university education (t=2.815, p=0.006), the number of the medical training center (t=-2.998, p=0.003), work type (t=-2.998, p=0.003), satisfaction with college life (t=5.280, p=0.000), and satisfaction with major (t=5.132, p=0.000). Empathy (r=-.520, p<.001) and self-regulation ability (r=-.330, p<.001) significantly negatively correlated with major variables, and the major factor influencing clinical practice stress levels was empathy. Conclusion: Extension of education and various experiences for improving empathy and developing management programs should be performed to decrease clinical practice stress on paramedic students.

Purpose: The lateral orbital wall fractures have been previously classified by some authors. As there are some limitations in applying in their own classifications, we hope to present a refined classification system of the lateral orbital wall fracture and to identify the correlation between the specific type of the fracture and clinical diagnosis. Methods: The facial bone CT scans and medical records of 78 patients with the lateral orbital wall fractures were reviewed in a retrospective manner. The classification is based on the CT scan. In type I, the fracture and its segments are away from the lateral rectus muscle and in type II, they are next to or slightly pushing the muscle in axial CT scan. In type III, the fracture segments compress and displace the longitudinal axis of the muscle or the optic nerve in axial view of CT scan. Type IV fracture includes multiple fractures found around the orbital apex or optic canal in coronal view of CT scans of the type I and type II fractures. Results: The most common fracture pattern was type I(43.6%), followed by type IV(29.5%), type II(20.5%), and type III(6.4%). As diplopia and restriction of extraocular muscles were found in type I and II fractures, severe ophthalmic complications such as superior orbital fissure syndrome, orbital apex syndrome, and traumatic optic neuropathy were found in type III and IV fractures almost exclusively. Conclusion: We propose an easy classification system of the lateral orbital wall fracture which correlates closely with ophthalmic complications and may help to make further treatment plan. In Type III and IV fractures, severe ophthalmic complications may ensue in higher rates, so early diagnosis and treatment should be performed.

Purpose: This study considered the effects and proper treatments of mandibular condyle fractures by comparing clinical differences and complications according to analysis and treatment plan. Methods: From September 2007 to August 2010, patients who were diagnosed with condylar fracture and monitored for more than 3 months were selected. Cases were divided in a reductive manner and evaluated by type and period of intermaxillary fixation (IMF), status of occlusion and trismus according to the Spiessle/Schroll method. A total 50 patients were examined. Results: The number of the unilateral condyle fractures was 45 and 30 patients had multiple fractures. Type of fracture was categorized by the Spiessle/Schroll method. There were 21 patients with type I, 11 patients with type II, 3 patients with type 3, 10 patients with type V and 5 patients with type VI; there were no patients with a type IV fracture. 11 patients were operated on with open reduction. Among them, 9 patients were type II and 2 patients were type I. For type I patients, an intra-oral approach was conducted with an endoscope and trocar. For 3 of the type II patients, an retromandibular approach was conducted and for the rest of the type II patients, the same approach as type I was used. The periods of IMF were 2.36 weeks (mean) in open reduction group and 2.9 weeks (mean) in closed reduction group and the total mean period is 2.78 weeks. All patients had stable occlusion after removing the IMF. Trismus occurred in 1 patient for open reduction and 5 patients for closed reduction. Facial nerve palsy was observed in one patient postoperatively that resolved after 6 months. Conclusion: In this study, similar prognosis was shown after an open and closed reduction was conducted. Therefore, treatments need to be planned depending on the degree of condyle fracture and the amount of displacement. Additionally, the period of IMF could be shortened with open reduction.

Objectives The purpose of this study is to improve the accessibility of Korean medicine by standardizing managements, improving quality of medical services, and reducing medical costs in ankle sprain by develop clinical pathway (CP). Methods The development of CP in this study is based on clinical practice guideline (CPG) for ankle sprain, and aims to maximize the quality of treatment, such as reducing treatment time and medical costs, and increasing patient satisfaction through standardized pathway. The CP was revised after consultation and review by the advisory committee. The advisory committee is consisted of a stakeholder group applying the CP. Results In previous research studies, there were no Korean medicine CP studies on ankle sprain. Based on CPG for ankle sprain and analysis of medical records, 6 types of time task matrix type CP (for Korean medicine doctors, medical assistant, patients) and 4 types of algorithm type CP (for Korean medicine clinics, Korean medicine hospitals, and cooperative practicing hospitals, public medical centers) were derived as a result. Conclusions Ankle sprain CP is expected to not only increase patient satisfaction and maximize the quality of treatment, but also reduce the financial burden of health insurance by reducing medical costs.
