Background: The study aimed to determine the type of capsular insertion and the extent of capsular elongation in anterior shoulder instability by quantitatively evaluating their computed tomography arthrographic (CTA) findings, and to investigate the correlation of these parameters with surgical outcomes. Methods: We retrospectively reviewed 71 patients who underwent CTA and arthroscopic capsulolabral reconstruction for anterior shoulder instability between April 2004 and August 2008. The control group comprised 72 patients diagnosed as isolated type II superior labrum anterior to posterior (SLAP) lesion during the period. Among the 143 patients, 71 were examined with follow-up CTA at an average 13.8 months after surgery. It was measured the capsular length and cross-sectional area at two distinct capsular regions: the 4 and 5 o'clock position of the capsule. Results: With regards to the incidence of the type of anterior capsular insertion, type I was more common in the control group, whereas type III more common than in the instability group. Anterior capsular length and cross-sectional area were significantly greater in the instability group than in the control group. Among patients of the instability group, the number of dislocations and the presence of anterior labroligamentous periosteal sleeve avulsion lesion were significantly associated with anterior capsular redundancy. Postoperatively, recurrence was found in 3 patients (4.2%) and their postoperative capsular length and cross-sectional area were greater than those of patients without recurrence. Conclusions: Capsular insertion type and capsular redundancy derived through CTA may serve as important parameters for the management of anterior shoulder instability.

Lactobacillus mucosae is a natural resident of the gastrointestinal tract of humans and animals and a potential probiotic bacterium. To understand the global protein expression profile and metabolic features of L. mucosae LM1 in the early stationary phase, the QExactive^TM Hybrid Quadrupole-Orbitrap Mass Spectrometer was used. Characterization of the intracellular proteome identified 842 proteins, accounting for approximately 35% of the 2,404 protein-coding sequences in the complete genome of L. mucosae LM1. Proteome quantification using QExactive^TM Orbitrap MS detected 19 highly abundant proteins (> 1.0% of the intracellular proteome), including CysK (cysteine synthase, 5.41%) and EF-Tu (elongation factor Tu, 4.91%), which are involved in cell survival against environmental stresses. Metabolic pathway annotation of LM1 proteome using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database showed that half of the proteins expressed are important for basic metabolic and biosynthetic processes, and the other half might be structurally important or involved in basic cellular processes. In addition, glycogen biosynthesis was activated in the early stationary phase, which is important for energy storage and maintenance. The proteogenomic data presented in this study provide a suitable reference to understand the protein expression pattern of lactobacilli in standard conditions

Background: The subciliary approach is commonly used for reconstruction of orbital wall or zygomaticomaxillary fractures. However, this approach is associated with postoperative complications, especially lower eyelid malposition. We report the experience of managing postoperative lower eyelid malposition with triamcinolone acetonide. Methods: A retrospective review was performed for all traumatic facial fractures requiring surgery via the subciliary approach at Chosun University Hospital in 2014. For each patient meeting inclusion criteria, the medical chart was reviewed for demographic information and postoperative course, including the presence of postoperative eyelid malposition or scleral show. Results: The review identified 189 cases in which the subciliary approach was used, and postoperative lower eyelid malposition was found in 7 cases (3.7%). For these 7 patients, the mean therapeutic period (interval to correction of the malposition) was 10.5 weeks (range, 8 to 14 weeks). On average, patients received 3 injections of triamcinolone. In all cases, degrees of the malposition were improved, and none of the patients required an operative intervention to correct the malposition. Conclusion: Triamcinolone injection is an appropriate treatment modality for lower eyelid malposition after subciliary approach. Treatment duration is relatively short, requiring fewer than 4 outpatient clinic visits, with relatively earlier recovery compared to conservative "wait-and-see" management.

The study is based on a two-year research study titled 'A study on the Development of the Programs for Housing Policy to support Multi-family Housing Remodeling in Korea'. The primary purpose of this two-year study was to recommend governmental program initiatives for supporting multi-family housing remodeling activities in Korea. As a part of this research study, this article was written based on the results from the two surveys regarding multi-family housing remodeling in the United States and Korea, and a focus group with housing researchers affiliated to the Joint Center for Housing Studies. Major research findings are presented as follows: First, there have been various types of supportive programs for single- and multi-family housing remodeling in the United States. Those have focused on lower income families than middle income families. Compared with the programs in the United States, the apartment remodeling in Korea has been focusing on small population of the multi-family housing owners. Apartment remodeling in Korea needs supportive programs for rental housing remodeling and the housing remodeling for low-incomes. Second, there have been various types of remodeling activities made in multi-family housing properties in the United States. Size of remodeling project also varied. Their remodeling activities were based on the long-term repairing plans initiated by professional apartment management groups. For making our multi-family housing properties more sustainable, we also need to have the long-term repairing plans. Third, the apartment property remodeling has been regarded as a substitute of reconstruction of apartment properties. However, remodeling should be regarded as one of the most efficient ways to extend the life-cycle of apartment buildings. Thus, benefits and executive plans of apartment remodeling should be studied by a professional research center under our governmental responsibilities as done in the United States.

Purpose: The management of metal-induced field inhomogeneities is one of the major concerns of distortion-free magnetic resonance images near metallic implants. The recently proposed method called "Slice Encoding for Metal Artifact Correction (SEMAC)" is an effective spin echo pulse sequence of magnetic resonance imaging (MRI) near metallic implants. However, as SEMAC uses the noisy resolved data elements, SEMAC images can have a major problem for improving the signal-to-noise ratio (SNR) without compromising the correction of metal artifacts. To address that issue, this paper presents a novel reconstruction technique for providing an improvement of the SNR in SEMAC images without sacrificing the correction of metal artifacts. Materials and Methods: Low-rank approximation in each coil image is first performed to suppress the noise in the slice direction, because the signal is highly correlated between SEMAC-encoded slices. Secondly, SEMAC images are reconstructed by the best linear unbiased estimator (BLUE), also known as Gauss-Markov or weighted least squares. Noise levels and correlation in the receiver channels are considered for the sake of SNR optimization. To this end, since distorted excitation profiles are sparse, $l_1$ minimization performs well in recovering the sparse distorted excitation profiles and the sparse modeling of our approach offers excellent correction of metal-induced distortions. Results: Three images reconstructed using SEMAC, SEMAC with the conventional two-step noise reduction, and the proposed image denoising for metal MRI exploiting sparsity and low rank approximation algorithm were compared. The proposed algorithm outperformed two methods and produced 119% SNR better than SEMAC and 89% SNR better than SEMAC with the conventional two-step noise reduction. Conclusion: We successfully demonstrated that the proposed, novel algorithm for SEMAC, if compared with conventional de-noising methods, substantially improves SNR and reduces artifacts.

There are many reports of the surgical management for the craniofacial abnormalities arising from the irradiation of the head and face for treatment of childhood cancers. Since the mordern combined-modality theraphy for childhood cancers began in the late 1960s and the early 1970s, recent reports have described the occular, dental and maxillo-facial abnormalities after irradiation in long-term survivors of cancers of the head and face. The resultant deformities may be known to be difficult to reconstruct with surgical techniques. This paper describes the late reconstructive surgery for the unilateral orbital and malar hypoplasia after eyeball enucleation and irradiation during childhood to correct the facial asymmetry and expand the contracted orbital socket into the functional dimension for the retaining eyeball prosthesis with spherical implant. We reports the satisfactory preliminary results from the midfacial osteotomy through the supero-lateral orbital rim and malar bone and the antero-lateral repositioning with the autogenous bone grafting in 26 year-old female patient who will be planned to make the new eyeball prosthesis by the department of ophthalmology.

An early stage of general hospital in Korea was the quantitative growth period. Remodeling has been required to meet the increasing medical demands. To accept the change of paradigm and management operation method, remodeling occurred from the 20th century. Remodeling plans are difficult to define the direction of the detailed plan due to various factors in the beginning of the construction, Therefore, it is necessary to analyze the possibility and limitation of a feasible remodeling plan of general hospitals through the comparison of existing hospital before remodeling and after the remodeling takes effect. A comparison of the researched hospital's blue prints before and after the remodeling and recently built hospital's blue print, analyzed characteristic of the space variation by the remodeling. The purpose of research is to confirm a possibility and limitation of remodeling of general hospitals comparing with merits and faults of extension, reconstruction, and construction. In conclusion, the area of remodeling hospitals increase mostly medical department(ward, outpatient department, inpatient department) and subsidiary facilities, but the area of ward and inpatient department are less than the new hospitals. Especially, public area is greatly increased by the diversification of corridor function. Also, remodeling hospitals represent a limitation to plan departments in need of equipment-intensive space. To address this problem, expansion space is used mainly with inpatient department and existing space is placed mainly with low-impact department by equipment ; outpatient department, administration department.

Purpose: Plastic surgeons are responsible for the management of spinal cord injury patients with upper and lower extremity reconstruction, pressure sore, and wounds. Derailment of autonomic nervous systems caused by injury to the spinal cord may result in fatal autonomic dysreflexia. Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord lesion above the splanchnic outflow(T6). It is characterized by a sudden onset and severe increase in blood pressure and is potentially life threatening. The other classic symptoms are headache, chest pain, sweating, and bradycardia. In order to lower the blood pressure, it is important to remove the noxious stimulus for autonomic dysreflexia. If such symptoms last for more than 15 minutes despite conservative interventions, antihypertension drugs are recommended. Methods: In this case study, we report an autonomic dysreflexia case that developed in a 45 year-old tetraplegia patient with sacral pressure sore. When he got bladder irrigation, his blood pressure went up very high and his mentality became stuporous. He was sent to ICU for his blood pressure and mental care. ICU care made his vital sign stabilized and his mentality alert. Results: After the patient underwent proper treatment like inotropic agent, he was transferred to the general ward and his pressure sore on sacral area was coveraged with gluteus maximus myocutaneous advancement flap. Conclusion: If treatment is not effective, the patients have to undergo sudden, severe hypertension, which can cause stroke or death. To provide safe and effective care, plastic surgeons should be able to recognize and treat autonomic dysreflexia.

Purpose: Median cleft of upper lip is defined as any congenital vertical cleft through the midline of the upper lip. It is uncommon, its embryological pathogenesis remains unexplained to date. The authors hereby report a rare case of median cleft of the upper lip associated with enlarged frenulum and palatal mass. This case offers some understanding of the possible embryologic development of this anomaly. Methods: A 10-month-old boy born by normal vaginal delivery at full-term had a notch in the midline of the upper lip with widened philtrum along with enlarged median frenulum, alveolar cleft, and mass of the hard palate. We performed en bloc resection of the enlarged frenulum and palatal mass and cheiloplasty under general anesthesia. Results: Histological examination revealed that the frenulum and palatal mass was consisted of fibrous tissue with normal mucous membrane. The postoperative course was satisfactory. Conclusion: A rare case of median cleft of the upper lip with associated enlarged frenulum and palatal mass was presented with proper surgical management. The surgical technique includes marginal excision of the clefted epithelium and reconstruction of orbicularis oris muscle, in addition to en bloc resection of the palatal mass and frenulotomy.
