The superior shoulder suspensory complex is composed of glenoid fossa, coracoid process, coracoclavicular ligament, distal clavicle, acromioclavicular ligament, acromion. Traumatic double disruptions of this complex lose its suspensory action on the shoulder joint and result in functional loss and deformity. Careful radiologic evaluation and appropriate management are required for injuries to this complex. Ipsilateral fractures of clavicle and scapula create unstable anatomic situation on shoulder joint. Conservative treatment usually fails to achieve good functional recovery due to rotator cuff weakness, nonunion, delayed union, malunion and neurovascular injury. Authors studied the result of operative treatment of ipsilateral clavicle and scapular fractures to prevent such complications. Seven cases were treated with open reduction and internal fixations of clavicle alone or clavicle and scapula simultaneously and followed up for nineteen months(twelve months - thirty-eight months). All but one patient showed good or excellent functional result according to the scoring system of Rowe. Poor result was developed in the case which had brain injury. Rigid fixations of clavicle alone or clavicle and scapular fractures both can achieve stable reduction of the fractures and prevent sequelae. We concluded that operative treatment of ipsilateral fractures of clavicle and scapula is safe and yields predictable good results.

Breast feeding can play a very important role in the development of strong, healthy children. Many studies over the years have shown that breast milk provides defense against common ailments of childhood such as otitis media, gastrointestinal distress, and atopic diseases (allergies). For these reasons the American Academy of Pediatrics recommends breast feeding for at least the first twelve months of an infant's life. Goals of the Health People 2010 Initiative include that at least 75% of mothers will be breast feeding upon discharge from the hospital and at least 50% will be still nursing at six months post-partum. Currently, about 60% of new mothers initiate breast feeding and about 26% are still breast feeding at six months. However, research has shown that breast feeding trends are below these averages in rural areas of the United States. This may be due in part to lack of breast feeding knowledge and teaching in rural areas. Rural hospitals and birthing centers have not initiated many of the breast feeding promotional programs, such as the Baby Friendly Hospital Initiative and Best Start, that have been successful in improving breast feeding trends in urban areas. Often new mothers who live in rural areas do not have access to a lactation consultant to help them with proper follow up. This paper will examine these concerns and propose recommendations to improve breast feeding in rural areas.

Objective : The maintenance of the correction of kyphotic deformity is one of the difficult problem in tuberculous spondylitis after anterior debriment and fusion with tricortical bone graft. The goal of this study is to find out the efficacy of titanium mesh cage impacted with autogenous bone chip in tuberculous spondylitis treated with anterior intervertebral fusion. Materials and Method : Twelve patients were treated with anterior intervertebral fusion using titanium mesh cage for tuberculous spondylitis from January 1996 to June 1999. We analized the changes in the correction of kyphotic deformity, changes of ESR and CRP, fusion state and recurrence after anterior intervertebral fusion with titanium mesh cage. Results : Clinical symptoms were improved in all twelve patients without any neurologic complications. The mean kyphotic angle corrected was 7.3 degrees immediately after operation, but the loss of correction of kyphotic angle was 2.2 degrees after 3 months and 2.6 degrees after 6 months. We found that the loss of correction of kyphotic deformity occurred mainly within the first 3 months after surgery. Only one patient, suffered from acute hepatic failure after first operation and had an insufficient anti-tuberculous medication therapy, showed recurrence of tuberculous spondylitis after 6 months. The patient underwent a second operation with posterior fixation procedure with good outcome. The changes of ESR and CRP were not specifically important factor to reveal recurrence of tuberculosis of the spine in our series. Conclusion : The surgical procedure of tuberculous spondylitis using titanium mesh cage with bone chip seems to be an effective procedure to minimize loss of the correction of kyphotic deformity without any aggravating inflammatory change and recurrence with titanium mesh cage, when sufficient debridement and anti-tuberculous chemotherapy are achieved.

Purpose: This study was designed to determine the influencing factors and clinical course of pathologically proven cases of radiation-induced brain injury (RIBI). Materials and Methods: The pathologic records of twelve patients were reviewed; these patients underwent surgery following radiotherapy due to disease progression found by follow-up imaging. However, they were finally diagnosed with RIBI. All patients had been treated with 3-dimensional conventional fractionated radiotherapy and/or radiosurgery for primary or metastatic brain tumors with or without chemotherapy. The histological distribution was as follows: two falx meningioma, six glioblastoma multiform (GBM), two anaplastic oligodendroglioma, one low grade oligodendroglioma, and one small cell lung cancer with brain metastasis. Results: Radiation necrosis was noted in eight patients and the remaining four were diagnosed with radiation change. Gender (p = 0.061) and biologically equivalent dose $(BED)_3$ (p = 0.084) were the only marginally influencing factors of radiation necrosis. Median time to RIBI was 7.3 months (range, 0.5 to 61 months). Three prolonged survivors with GBM were observed. In the subgroup analysis of high grade gliomas, RIBI that developed <6 months after radiotherapy was associated with inferior overall survival rates compared to cases of RIBI that occurred ${\geq}6$ months (p = 0.085). Conclusion: Our study demonstrated that RIBI could occur in early periods after conventional fractionated brain radiotherapy within normal tolerable dose ranges. Studies with a larger number of patients are required to identify the strong influencing factors for RIBI development.

The purpose of this study was to evaluate the changes of interproximal bone density by means of videodensitometer and to examine the clinical applicability of videodentitometer to assess the periodontal disease activity.Twelve interproximal sites, with periodontal pockets deeper than 5mm and vertical loss of bone on standard dental radiograph, were treated by subgingival curettage. The papilla bleeding index, the plaque index, the degree of mobility, the depth of pockets, and the level of attachment were measured. Standardized reproducible radiographs were taken by using the occlusal stent with parallelling film holder. The density of the interdental bone was measured on the radiographs by a videodensitometer at three levels: the most 'superficial' level; the 'deep' level, arbitrarily 1.5mm below: and the 'apical' level, where no bony changes were to be expected. The clinical parameter and the radiographical change were measured at initial, and 1 month, 3 months, and 6 months after treatment.The results were as follows :1. The papilla bleeding index and the degree of mobility decreased significantly until 3 months after subgingival curettage and showed the Same level in the remaining experimental periods. 2. The pocket depth mainly decreased due to the gingival recession until 1 month after treatment, but to the attachment gain after 1 month. 3. The density of the interdental bone did not show a significance increase until 1 month after treatment, but showed a steady increase throughout the 6 months of observation. 4. The close relationships were shown between the decrease in pocket depth and the gain of attachment and the improvement of bone density at 6 months after treatment.

Objectives : Vocal fold augmentation using injectable material is an easy and simple operation. This study is to evaluate the histology of minced and injected autologous auricular cartilage and fat graft in the augmentation of unilateral vocal fold paralysis using a canine model for two years. Study Design : A prospective study with the contralateral side of the larynx used as the control Methods : Twelve dogs were operated. At first, a piece of auricular cartilage was harvested from ear and minced into tiny chips with a scalpel and scissors. And also, a piece of fat tissue was harvested from inguinal area and minced into tiny chips with a scalpel and scissors. The minced cartilage and fat-paste (0.2ml) was injected using a pressure syringe into the paralyzed thyroarytenoid muscle under direct laryngoscopy. Two animals were sacrificed at 3 days, three at 3 weeks. two at 3 months. one at 6 months, one at 12 months, three at 24 months. Each dog underwent laryngectomy and serial coronal sections of paraffin blocks from the posterior part of the vocal fold were made. Result : There was no significant complication perioperatively and during follow-up. There was acute inflammatory findings in the graft at 3 days and 3 weeks. Only a very small proportion of the injected cartilage was absorbed due to the degenerative change and the overall volume was preserved even when the cells died out. The injected cartilage remained in the larynx until 24 months. Conclusion : The autologous cartilage implant using auricular cartilage was the ideal vocal cord augmentative material for the treatment of glottic incompetence.

There are many chapters in "The Yellow Emperor's Internal Classics(黃帝內經)" regarding systemizing months, seasons, meridians, the internal organs(藏府), and parts of body, However it is very confusing because in every chapter, they have different standards. In "Maek'ae(脈解)" of "Plain Questions(素問)", months are related to three $\breve{U}$m and three Yang(三陰三陽). In "Kuoh'imnon(九鍼論)" of "Miraculous Pivot(靈樞)", parts of body are related to seasons and days. In "$\breve{U}$myanggyeirwol(陰陽繫日月)" of "Miraculous Pivot(靈樞)", 12 meridians are related to the Heavenly Streams & Earthly Branches(干支). In "Chinyogy$\breve{o}$ngjongnon(診要經終論)" of "Plain Questions(素問)", the internal organs(藏府) and the head are related to months. In "K$\breve{u}$mgwejin$\breve{o}$llon(金匱眞言論)" of "Plain Questions(素問)", parts of body are related to four seasons. Following statements can be concluded when analyzed with the theory of y$\breve{o}$k(易). 1. Both in "The Yellow Emperor's Internal Classics(黃帝內經)" and "Chuyok(周易)", $\breve{U}$m and Yang are thought as the basis of everything and every change that occur in this universe is by the fluctuation of Yin and Yang. This rule is also applied to our body. 2. "Maek'ae(脈解)" of "Plain Questions(素問)" is related to the theory of twelve principal divinatory symbols and "Kuoh'imnon(九鍼論)" of "Miraculous Pivot(靈樞)" is closely related to the theory of eight divinatory saymbols-direction.

Purpose: To investigate the frequency, presentation, management, and outcome of cytomegalovirus (CMV) infection in pediatric patients who underwent renal transplantation. Methods: We performed a retrospective chart review of 70 patients under the age of 18, who underwent renal transplantation between January 1990 and November 2014. A diagnosis of CMV infection was based on serology, molecular assays, antigenemia assays, and culture. CMV infection was defined as detection of virus and CMV disease was diagnosed when clinical signs and symptoms were present. Results: The number of patients with CMV infection was 18 (25.7% of renal transplant recipients). Twelve were male (66.7%), and the $mean{\pm}standard$ deviation (SD) age at infection was $13.3{\pm}3.9$ years. Median time of infection after renal transplantation was 4 months (range 1.0-31.0 months). Pretransplantation CMV status in the infected group was as follows: donor (D)+/recipient (R)+, 11 (61.1%); D+/R-, 7 (38.9%); D-/R+, 0; and D-/R- 0. Nine patients had CMV disease with fever, leukopenia, thrombocytopenia, or organ involvement such as enteritis, hepatitis, and pneumonitis. The age of disease occurrence was $13.1{\pm}3.9$ years and the median time to disease onset after renal transplantation was 8 months (range 1.0-31.0). Immunosuppressive agents were reduced or discontinued in 14 patients (77.8%), antiviral agents were used in 11 patients (61.1%), and all patients with CMV infection were controlled. Conclusions: A quarter of the patients had CMV infection about 4 months after renal transplantation. CMV infection was successfully treated with reduction of immunosuppressants or with antiviral agents.

From August 1982 to December 1991, 58 consecutive infants with tetralogy of Fallot underwent primary repair. Age ranged from 22 days to twelve months [n=58, 8.7$\pm$2.7 months] and body weight from 3.1 to 13 kilograms [n=58, 7.8$\pm$1.7 kilograms]. Qne infant had absence of the pulmonary valve; one had Ebstein`s anomaly and one had supramitral ring. Thirty-two patients [56%] experienced anoxic spell. Preoperative pulmonary artery indices were measured in 38 cases, ranging 126-552mm2/M2BSA[n=38, 251$\pm$79mm2/M2BSA]. All infants required a right ventricular outflow tract patch; in 41, the patch extended across the pulmonary valve annulus, in 13 of them, monocusps were constructed. All had patch closure of ventricular septal defect. Two infants had REV operation for avoiding injury to the canal branch of the right coronary artery which cross the right ventricular out flow tract. Post repair PRV/LV were measured at operating room in 40 cases, which revealed mean value of 0.49$\pm$0.12 [range: 0.25-0.74]. The hospital mortality was 10.3% [6 patients], and causes of deaths were right heart failure due to sustained right ventricular hypertension[4] and right ventricular outflow tract obstruction, intractablesuraventricular tachyarrhythmia[1], hypoxia[1] due to residual right to left shunt across the atrial septal defect in patient associated with Ebstein`s anomaly. All infants were doing well at follow-up from 1 to 101 months[20.6 months /patient, 1, 072 patient-month] Serial postoperative echocardiograms revealed no residual ventricular septal defects and estimated RVOT gradients between 0 and 40 mmHg except 3 cases [50, 50, 60 mmHg]. There were no late deaths and late ventricular arrhythmias or congestive heart failure. Redo operations were done in 2 cases because of residual right ventricular outflow tract obstruction. This experience with infants with tetralogy of Fallot suggests that, if mortality is tolerable, eletive repair of tetralogy of Fallot could be reasonably undertaken during the first year of life, and even better results could be anticipated along with improvement of methods of myocardial protection and postoperative care.

The quality of Korean doenjang, which was traditionally made for this study, was monitored for physicochemical properties, antioxidant capacity, and sensory properties at six months intervals for three years. The collected data were comprehensively analyzed using the k-means clustering via principal component analysis (PCA) to determine the optimal intake duration and sensory factors associated with acceptance. Doenjang samples were classified with every year interval based on PCA, and then the classified doenjang samples were further grouped into cluster one, two, and three based on the k-means clustering. In Cluster three, doenjang that was aged for thirty and thirty-six months, respectively, showed high total phenolic content, antioxidant capacity, superoxide dismutase like activity, and 2,2-diphenyl-1-picryl-hydrazyl radical scavenging capacity. Interestingly, along with acceptance, the levels of free amino acids and organic acids were higher in Cluster 3. The sensory factors found to be associated with acceptance included umami taste and brown color. In conclusion, this study proposes the intake of doenjang aged for thirty months based on its antioxidant activity and sensory properties although doenjang is usually ready after twelve months of aging.
