Highly cohesive, form-stable cohesive gel implants were introduced in 1993. This resulted in a paradigm shift in breast augmentation surgery. With the introduction of shaped textured implants, surgeon started to think in terms of shape and dimensions rather than volume and cup size. Basically most aspects of such breast augmentations are different. The way of selecting implants is different. Patient preoperative markings, surgical techniques, postoperative recommendations and results also differ. These are not mere new types of implant, but they represent a new concept in breast augmentation surgery. Surgeons who believe that form stable implants behave in the same way as non-form stable implants will tend to plan, select implants and perform surgery in traditional ways. Unfortunately, they are bound to encounter significantly more complications and problems. These implants are recently available in Korea since 2012 and will provide patients and surgeons with the ability of enhanced outcome and results if used properly; however there needs to be a transition from round cohesive gel implant thought process to a more comprehensive approach for the typical Korean plastic surgeon.

2.Visualization of Soft Tissue Venous Malformations of Head and Neck with 4D Flow Magnetic Resonance Imaging.
Neurointervention 2017;12(2):110-115
Evaluation of hemodynamics in venous malformation (VM) in the head and neck area is done by direct puncture venography before alcohol sclerotherapy, but it is difficult due to a variable degree of filling in from the artery and filling out into the draining vein. We present our preliminary experience of 4D MRI to evaluate VM hemodynamics. Four patients with venous malformation in the maxillofacial area underwent both 4D MRI and direct puncture venography before alcohol sclerotherapy. To find out appropriate velocity encoding (VENC) for VM, we applied 5-50 cm/sec VENC. Significant high-flow foci demonstrated by phase changes in magnitude images were compared with lesion types shown on a direct puncture venogram. Detection of flow in VM was possible in magnitude images or phase-difference images when VENC was set to less than 30 cm/sec. Appropriate VENC for VM was regarded as less than 5 cm/sec. High-flow areas in the dilated venous sac demonstrated focal spots or linear band-like areas on phase changes of 4D MRI. Appropriate VENC application was mandatory to detect flow in VM. Flow information on 4D MRI provided flow information in VM which was not detected on a direct puncture venogram in the compartmentalized lesion and thus can make alcohol sclerotherapy safer.

Essential thrombocythemia in childhood is a rare clonal myeloproliferative disorder in the multipotent stem cell origin and is associated with an increased risk of thrombohemorrhagic complications. The one of diagnostic criteria is a platelet count of more than 600,000/mm3. We diagnosed this disease in 8 year old boy incidentally and treated with hydroxyurea. We report a case of essential thrombocythemia to summarize the current trends in the diagnosis and management with a brief review of related literatures.

Purpose:
This study assessed the alignment between Korean medical schools’ mission statements (MSs) and Korean Doctor’s Role (KDR) domains, considering school characteristics.
Methods:
We analyzed the South Korean medical school’s MS characteristics using a mixed-methods approach. Quantitative analysis preprocessed MS text data to identify concept words, while qualitative content analysis categorized information into predefined KDR domains and extracted themes from other parts.
Results:
At the KDR domain level, “social accountability” was the most frequent, followed by “education and research” and “patient care,” while “professionalism” had the least frequency. At the competency level, the most frequent domains were “involvement in public and global health initiatives,” while “self-regulation based on professional leadership” and “professionalism and self-management” were not present.
Conclusion
The study found that the majority of MSs had a homogeneous pattern and included traditional themes. Medical schools should evaluate and incorporate missing elements in their MSs to reflect the institution’s own purpose and current societal needs.

Cranial-nerve disorders can be caused by a wide spectrum of diseases, including congenital, inflammatory, and tumorous diseases, and are often encountered in practice. However, the imaging of cranial-nerve disorders is challenging, and understanding the anatomical differences of each region is essential for conducting the best protocols and for detecting subtle changes in cranial nerves during magnetic resonance imaging (MRI) examinations. In this review we discuss which MRI techniques are best for observing normal and pathologic appearance, according to the different regions of the cranial nerves.

Protein-energy malnutrition, PEM, and increased hs-CRP level are considered to be associated with increased risk of cardiovascular disease (CVD) in hemodialysis (HD) patients. This is commonly referred to as the vicious circle of malnutrition-inflammation-atherosclerosis cardiovascular disease (MIA syndrome) in chronic kidney disease (CKD). Low protein intake can decrease the serum level of albumin and increase inflammational markers; further, both low serum albumin and high hs-CRP are independent risk factors for all-cause mortality in HD patients. The aim of this study is comparing the serum levels of albumin and hs-CRP in HD patients according to the protein intake levels. The total number of subjects was 60 hemodialysis patients; they were grouped by dietary protein intake: low protein intake group (LPI, protein intake < 1.0 g/kg IBW, 11 men and 19 women) and adequate protein intake group (API, protein intake > or = 1.0 g/kg IBW, 12 men and 18 women). Blood biochemical parameters, nutrient intake, and dietary behaviors were compared between the LPI and API groups. The LPI group showed a significantly lower serum level of albumin and higher serum level of hs-CRP than the API group (p < 0.05). The LPI group showed a significantly lower intake of most nutrients than the API group (p < 0.05). Index of Nutritional Quality of most nutrients of the LPI and API groups were lower than 1.0. Dietary protein intake was positively correlated with the serum level of albumin (r = 0.306, p < 0.05) and negatively correlated with the serum level of hs-CRP (r = -0.435, p < 0.01). The serum level of hs-CRP was negatively correlated with that of albumin (r = -0.393, p < 0.01). According to these result, serum albumin and hs-CRP in HD patients were influenced by the protein intake levels. To prevent MIA syndrome, it is necessary to improve nutritional status, especially in protein and energy.

PURPOSE: To evaluate the effect of gadoxetic acid on the measurement of the stiffness value of MR elastography (MRE) used to evaluate hepatic fibrosis (HF). MATERIALS AND METHODS: MRE was obtained in 32 patients with clinically suspected chronic liver disease, both before and after injection of gadoxetic acid. Two independent reviewers measured the stiffness values of the liver parenchyma on elastograms. The mean liver stiffness values were compared in the pre- and post-contrast MREs using the paired t-test. Intra-rater and inter-rater correlation was assessed using the intraclass correlation coefficient (ICC). The accuracy, sensitivity, and specificity of both pre- and post-contrast MREs was evaluated for the diagnosis of significant HF (> or = F2) using cut off value of 3.1 kPa. RESULTS: There were no significant differences in the stiffness values of the liver parenchyma on pre- and post-contrast MREs (p = 0.15 and 0.38 for each reader, respectively). Regarding intra-rater correlation, excellent agreement was noted on rater 1(ICC = 0.998) and rater 2 (ICC = 0.996). Excellent correlation regarding the measured stiffness values was noted on both pre- and post-contrast MREs (ICC = 0.988 for pre-contrast, ICC = 0.993 for post-contrast). The accuracy, sensitivity, and specificity of the pre- and post-contrast MREs for differentiating significant HF (> or = F2) from < or = F1 were same as 71%, 60%, and 100%, respectively. CONCLUSION: As there was no significant difference in the stiffness measurements seen on MREs before and after administration of gadoxetic acids, it is therefore acceptable to perform MRE after contrast injection in order to evaluate HF.

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.
