Since the first report by Tansini in 1896, the latissimus dorsi muscle free flap has been widely used for various types of soft tissue defect due to reliable anatomy with a sufficient diameter of neurovascular pedicle and a sizable muscle. However, for relatively small soft tissue defect, latissimus dorsi free flap offers several distinct disadvantages of donor site including loss of the posterior axillary fold and flattening of the posterolateral chest wall, weakness of upper arm strength in extension, adduction and internal rotation. We treated three patients having various types of soft tissue defect using segmental latissimus dorsi muscular free flap depending on its descending branch of thoracodorsal neurovascular pedicles. There were no serious complications during 18 months of mean follow-up. We concluded that this method has some advantages such as no weakness of strength of the upper arm including walking on crutches, preserving the posterior axillary fold, preventing winging of the scapula and increased chance of using a flow-through technique. Here we present our cases of reconstruction of soft tissue defect using segmental latissimus dorsi free flap with a review of the literature.

Natural cytotoxicity mediated by natural killer (NK) cells is believed to play an important role in host anticancer defense mechanisms. The aim of this study is to compare the number of NK cells in patients with colorectal cancer and hemorrhoids, and before and after surgery in patients with colorectal cancer. Twenty colorectal cancer patients and twenty hemorrhoid ones were studied. Venous blood samples were obtained preoperatively, and on the 7th, and 14th postoperative days. Mononuclear cells were isolated over Ficoll-Hypaque gradients, and T cells, B cells, and NK cells were measured with CD3 FITC (T cell), CD 19 PE (B cell), and CD56 FITC (NK cell) antibody, The number of T cell (/mm3) was 1224, 1280, and 1125 at preoperative, 7th, and 14th postoperative day in hemorrhoid patients and 1195, 901, and 1060 in colorectal cancer patients respectively. The number of B cell (/mm3) was 243, 160, and 250 in hemorrhoid patients and 147, 78, and 113 in colorectal cancer patients. The number NK cell (/mm3) was 148, 156, and 143 in hemorrhoid patients and 129, 85, and 128 in colorectal cancer patients. There was no difference among Dukes stages in the number of NK cells. In conclusion, the number of NK cells was not changed in colorectal cancer patients compared with hemorrhoid ones. Major operation changed the number of NK cells in colorectal cancer patients.

To define the basic sequential events of the healing process in normal fracture and evaluate the role of growth regulatory molecules and extracellular matrix components, the expression of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), type I and II collagen, and chemistry during the healing process of an experimental fracture of tibia in 41 adult rats for 7 weeks using ABC methods. The phases of inflammation, reparation, and remodeling followed each other in sequence. The inflammatory phase was characterized by hemorrhage, edema, and infiltration of inflammatory cells on the first day. During the reparative phase, the undifferentiated mesenchyme undergoes rapid chondrogenesis, followed by endochondral ossification and supplemented by appositional bone formation. At day 3, the expression of TGF-β and PDGF was noted in the undifferentiated mesenchymal cells and from day 5, these two growth factors were detected in the osteoblasts and extracellular matrix in areas of endochondral ossification and newly formed periosteal bone. From day 3, the expression of type I collagen and osteonectin was noted in the osteoblasts and extracellular matrix in both endochondral ossification and appositional bone growth as a marker of ossification. From day 3, type III collagen was mainly expressed in the plump mesenchymal cells showing chondroid differentiation and chondroid matrix as a marker of cartilaginous reparative phase. From day 14, these growth factors and extracellular matrix components were decreased in staining intensity and at the 5th week, the histology and immunostaining pattern were similar to the mature bone.

Traumatic brain injury (TBI) is one of the leading causes of death in the pediatric population in Korea. In addition, it can cause disability in children and adolescents, with physical and mental consequences. This causes a substantial burden on the health care system and occurs globally and not just in Korea. We searched and reviewed current data on the epidemiologic characteristics of pediatric TBI in Korea. Our review provides the recent epidemiological trend mainly focusing on incidence and mortality along with worldwide reported data. This review will be helpful to understand the global epidemiology of pediatric TBI and its differences between countries.

Gliomas are the most common pediatric tumors of the central nervous system. In this review, we discuss the clinical features, treatment paradigms, and evolving concepts related to two types of pediatric gliomas affecting two main locations: the optic pathway and thalamus. In particular, we discuss recently revised pathologic classification, which adopting molecular parameter. We believe that our review contribute to the readers' better understanding of pediatric glioma because pediatric glioma differs in many ways from adult glioma according to the newest advances in molecular characterization of this tumor. A better understanding of current and evolving issues in pediatric glioma is needed to ensure effective management decision.

BACKGROUND: To reduce the amount of homologous transfusion with its inherent problems of transmission of viral hepatitis, acquired immune deficiency syndrome and others, many institutions use comprehensive blood conservation methods (CBCM) in open heart and major aortic operations. The purpose of this study is to compare the amount and cost of homologous transfusion and the efficacy of coagulation between patients with or without CBCM adoption. METHODS: We prospectively assessed available CBCM of our institution in 20 patients, comparing the requirements of blood products, their cost and the efficacy of blood coagulation with those of another 20 patients similar in age, types of operation, operation difficulty and duration of bypass time retrospectively. RESULT: Fewer whole blood and platelet concentrates were transfused in patients with CBCM (p<0.05). There are no significant differences in the amount of used packed red blood cell and fresh frozen plasma between two groups. Partial thromboplastin time is significantly short in patient with CBCM (p<0.05). The prevalence of complications and mean extra-financial cost for using cellsaver, platelete pheresis and homologous blood products are low in patients with CBCM. CONCLUSIONS: The CBCM requires additional cost won but CBCM reduces the requirements of homologous blood effectively.
