Laparoscopic surgery has become popular in the past few decades, owing to less postoperative pain, fast recovery, and better cosmetic outcomes. The laparoscopic approach has been employed in pediatric surgery for the same reasons. After the first attempts of single incision laparoscopic appendectomy in pediatrics in 1998, single incision laparoscopic surgery (SILS) has recently been proven to be safe and feasible for the pediatric population. However, limitations have been reported for SILS, such as the wide learning curve, compared to standard laparoscopic surgery, and the restricted number of hospitals with surgical training programs including SILS. In this study, we intend to present our initial experiences with SILS in children, and to describe the technique, instruments used, and outcomes. This is a retrospective study of 71 pediatric patients who underwent SILS, at a tertiary medical center, between September, 2012 and August, 2013. Electronic medical records were reviewed for demographics, type of procedure, operation time, use of additional ports, conversion to open surgery, complications and hospital stay. Additional ports were inserted in 4 cases, for the purpose of traction. Postoperative complications were noted in 13 cases, which were mostly related to wound inflammation or formation of granulation tissue. According to our analyses, patients with complications had significantly longer use and more frequent use of pain killers. Notwithstanding the small sample size, many of the procedures performed in pediatric patients seem to be possible with SILS.

Bronchogenic cysts, though known as a relatively common malformation of the mediastinum, were rarely discussed in Korean literatures. Since the surgical removal of asymptomatic lesions was adopted as the reasonable therapeutic principle, the incidence of bronchogenic cysts were found to be higher than previously expected. Two cases of bronchogenic cysts operated on in The Dept. of Thoracic Surgery, Korea University Woo Sok Hospital were reported and related literatures were reviewed. Case 1. 5 year old boy with chief complaints of bulging cystic mass on left supraclavicular region during straining or coughing since his age of 2 was admitted, and cystogram with Lipiodol revealed hen-egg sized mass in the left antero-superior mediastinum without any communication with bronchus or esophagus. Cyst was successfully removed under general anesthesia thru left supraclavicular incision, and pathological examination of the cyst revealed thin cystic wall lined with stratified columnar epithelium and it`s content was milky white mucoid fluid devoid of any bacterial growth. Case 2. 15 year old school girl has been noted slowly growing walnut-sized mass on anterolateral side of the neck for 4 months without any subjective symptom except cosmetic problem... Mass was aspirated to find milky white mucoid fluid in some loculation and yellowish turbid fluid in other part due to chronic infection. Cystic tumor was removed under local anesthesia, which was loculated in between the trachea and esophagus without any communication, and pathological diagnosis of the cyst was bronchogenic cyst with columnar epithelial cell lining with moderate chronic inflammatory cell infiltrations. Postoperative conditions of the two cases were all excellent with normal life.

Medical school students learn a lot about medical knowledge and clinical experience in the classroom. Teaching is a main focus in medical schools; therefore, it is necessary to identify the characteristics of good teaching. The aim of this study is to analyze the characteristics of high-quality education in medical schools. In this study, in-depth interviews were conducted over two weeks on twelve fourth-year medical students. Participants were asked to define high-quality education, list the general ways in which high-quality classes are delivered, mention cases where they have experienced high-quality teaching, and describe the attitude required of students to make high-quality education possible. The results showed that students want to be taught in an interactive way on the core content needed in an actual clinical setting for the goal of cultivating primary care physicians. They want their education to include not only medical knowledge, but also liberal art subjects such as politics, economics, sociology, culture and ethics education to help instill a sound value system. In particular, students stressed the importance of instructors delivering appropriate post-evaluation feedback, and they also emphasized that learner mindset and attitude is important in supporting high-quality teaching in class. This paper also summarizes the elements of high-quality teaching in terms of educational goals, content, and method, and examines cases of instructors who have delivered high-quality classes.

In recent years, as interest in maintaining beauty and a youthful appearance has grown, filler procedures such as soft tissue augmentation have become more popular. These fillers are sometimes seen as radiopaque shadows on radiographic images, either due to the fillers themselves or because of secondary reactions; such findings may present a diagnostic challenge to dentists. The present report describes 3 cases of dermal fillers observed in panoramic and cone-beam computed tomographic (CBCT) images. All 3 elderly female patients had filler injected into their cheeks and chin area for cosmetic purposes decades ago. On panoramic images, multiple symmetric radiopacities were observed in the facial area; on CBCT, these calcifications were seen in the subcutaneous tissue in various shapes and with varying density. In conclusion, dentists should be aware of the imaging characteristics of dermal filler, and should be able to differentiate dermal filler from other pathological findings.

Despite the fact that benign skin lesions can undergo malignant transformation, the necessity and timing of the surgical resection have yet to be established. In this study, we analyse three cases of benign-appearing skin lesions, which were found to be carcinomatous on histologic examination and review the literature regarding the importance of prophylactic removal of benign-appearing skin lesion. The first and second cases were female patients wishing for cosmetic surgery. The first patient had a benign-appearing lesion on dorsum nasi, and the second patient had an inconspicuous lesion right along the right nasolabial fold. The third patient was a middle-aged male with a pigmented lesion on the left cheek, who presented to the clinic only after having met the operating surgeon through an acquaintance outside the hospital setting. All of the lesions were suspected to be of benign nature and were excised for cosmesis only. However, histologic examination of these lesions showed that the first two tumors were basal cell carcinoma with the last tumor being squamouse cell carcinoma. Thus, it is considered that removal of benign like skin lesion will result in good prognosis of patients scheduled to undergo other surgery.

Viscarin is a tradename given to viscosifying carrageenans manufactured by FMC BioPolymer. The suitability of Vis car ins as rheology agents in mild cleansing applications has been investigated. Rheological properties, foam volume and clarity were measured to determine the impact of including 1 % Viscarin on 10% solutions of the following surfactants: acylglutamate, cocoamidopropyl betaine, PEG-80 laurate, sodium lauryl sulphate and sodium lauryol sarcosinate. Viscosity, pseudoplasticity and thixotropy of Viscarin/surfactant solutions varied with surfactant type. In all cases, the addition of Viscarin substantially increased viscosity. For example, at a shear rate of 1 sol, all surfactant solutions had viscosities <0.1 Pa s while viscosities of Viscarin/surfactant solutions ranged from 10 to 60 Pa s. By comparison, a solution of 1 % Viscarin had a viscosity of 0.3 Pa s. Clarity of surfactant solutions decreased in all cases on the addition of Viscarin. However, it was found that by including a mild solubilizing surfactant, such as PEG 40 hydrogenated castor oil, crystal clarity could be maintained in Viscarin/surfactant solutions. Viscarin increased the foam volume of sodium lauryolsarcosinate solutions from 10 ml to 220 ml and had no impact on the foam volume of the other surfactants tested. These results were used to formulate a clear, ultra-mild foaming cleansing gel based on sodium lauryol sarcosinate and Viscarin without the need for a secondary, foam-boasting surfactant. A mild shampoo was also formulated. Both products have excellent skin-feel and are capable of suspending bubbles and solid inclusions.

Chronic progressive external ophthalmoplegia (CPEO) is a complex slowly progressive mitochondrial disorder characterized by extraocular muscle weakness with or without multisystem involvement. The mainstay of therapy in a patient with CPEO is supportive. However, in moderate cases, surgery might be indicated including surgeries for ptosis and strabismus. In this article, we report a Saudi patient with CPEO due to compound heterozygous variants in the DNA polymerase gamma (POLG) gene c.2246T>C p.(Phe749Ser) and c.1735C>T p.(Arg579Trp), which are classified as pathogenic. Proper diagnosis with genetic testing confirmation is important to guide the management and counsel the patient about the prognosis and the management options. The patient was successfully managed with bilateral frontalis sling and illustrates the importance of surgical intervention to improve vision and cosmetic appearance in patients with CPEO. We emphasize the importance of multidisciplinary care in the management of cases of mitochondriopathy, especially CPEO.

Purpose: Among the various surgical methods used for the effective treatment of cystic lesion in the jaws historically, decompression procedure has some of superior prognosis compare to direct enucleation. In order to propose the efficacy of decompression we performed this retrospective study to compare decompression procedure with one-stage enucleation in clinical results and prognosis. Patients and Methods: We reviewed 175 patients who had been histopathologically diagnosed cystic lesions from 1996 to 2000 in our department. Patients who had been received decompression alone or secondary enucleation after decompression were 31 cases, and enucleation alone were 144 cases. The age and sex of the patients, the area, size, and histological type of the lesions, and detailed operation and complications including recurrence were investigated. The minimal follow-up period was 2 years. Results: In 31cases of decompression, male patients were 22cases(71%) similar to male predilection(62.3%) in total 175 cases. Cystic lesions were developed evenly in all age groups totally. Decompression was mainly performed in teenagers but enucleation was used in elder decades. In decompression cases the lesions were located in mandibular posterior, maxillary posterior, mandibular anterior, and maxillary anterior in order, which had some differences in total and enucleation cases. In enucleation cases, less than 3cm in size was 77.1% but larger than 3cm was 93.5% in decompression cases. Histopathologically, dentigerous cysts(54.8%), unicystic ameloblastomas(16.1%), and odontogenic keratocysts(12.9%) were seen in decompression cases and no recurrence or metaplasia and infection was observed. On the other hand, permanent tooth loss, numbness, recurrence, and so on were accompanied after enucleation. Conclusion: Although decompression procedure has disadvantages such as many of visiting times and slow recovery of the surgical defect, decompression is the best choice of treatment for large cystic lesions of the jaws, because it prevents functional and cosmetic defect, allows bone regeneration, and makes easy secondary enucleation.
