Limb salvage operations for osteosarcoma of the extremity usually consist of wide excision and skeletal reconstruction. Most osteosarcoma patients are anemic prior to the surgery as majority of them undergo preoperative neo-adjuvant chemotherapy; thus, it is necessary to treat anemia before and after the surgery since limb salvage operation tends to accompany significant blood loss. Despite the fact that blood transfusion has bad influence on prognosis, complication, and postoperative outcome of cancer patients, it is still considered as a standard management to fix anemia for limb salvage operations. We would like to present a case report in which the authors succeeded in performing limb salvage operations on patients with distal femur osteosarcoma without transfusion.

PURPOSE: We have evaluated changes of body composition for patients that underwent a radical gastrectomy for stomach cancer by the use of available bioelectrical impedance analysis during the first year following surgery. We plan to utilize these findings in nutritional and physiological studies. MATERIALS AND METHODS: We evaluated clinical changes in body composition in patients using the bioelectrical impedance method (Inbody 4.0, Biospace, Korea), between November 2003 to November 2004. A total of 98 patients agreed to enroll in this study among all of the patients that underwent a radical gastrectomy. RESULTS: The average weight decreased by 6.7%, and 9.4%, within the first and 6 months after surgery, respectively (P<0.01). The fat free mass (FFM) dropped by 4.9% within the first month and there were no more changes after this period (P<0.01). The fat mass (FM) and visceral fat area (VFA) decreased 24.3% and 14.1% within the first 6 months (P<0.01), respectively. The reduction effects for female patients were greater than for male patients for weight, FFM and VFA (P<0.05). The edema index was higher in patients with stage III-IV disease than in patients with stage I-II disease (P<0.05). There were significant differences for Billroth I and BillrothI II patients as compared to patients that underwent an esophagojejunostomy for a reduction of the FM, as measured in the in the 12th month after surgery (27.6%, 22.1%, and 41.2%, respectively; P<0.05). CONCLUSION: Since nutritional supplementation and an improvement in body weight loss after a radical gastrectomy is significantly related with quality of life, nutritional and physiological studies should be greatly considered. In this study, bioelectrical impedance analysis was very useful in analyzing the diminution of body composition and we hope this study on the nutritional and physiological aspects related to a radical gastrectomy will be useful for later studies.

Background: We aimed to investigate the annual incidence of trauma and stress-related mental disorder including acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) using the National Health Insurance Service Database. In addition, we estimated direct medical cost of ASD and PTSD in Korea. Methods: To examine the incidence, we selected patients who had at least one medical claim containing a 10th revision of the International Statistical Classification of Diseases and Related Health Problems code for ASD (F43.0) and PTSD (F43.1) and had not been diagnosed in the previous 360 days, from 2010 to 2017. We estimated annual incidence and the number of newly diagnosed patients of ASD and PTSD. Annual prevalence and direct medical cost of ASD and PTSD were also estimated. Results: The number of newly diagnosed cases of ASD and PTSD from 2011 to 2017 totaled 38,298 and 21,402, respectively. The mean annual incidence of ASD ranged from 8.4 to 13.7 per 100,000 population and that of PTSD ranged from 4.2 to 8.3 per 100,000 population, respectively. The incidence of ASD was found more in females and was highest among the 70–79 years of age group and the self-employed individuals group. The incidence of PTSD was also more common in the female group. However, the incidence of PTSD was highest in the 60–69 years of age group and in the medical aid beneficiaries group. The annual estimated medical cost per person of ASD ranged from 104 to 149 US dollars (USD). In addition, that of PTSD ranged from 310 to 426 USD. Conclusion From 2011 to 2017, the annual incidence and direct medical cost of ASD and PTSD in Korea were increased. Proper information on ASD and PTSD will not only allows us to accumulate more knowledge about these disorders themselves but also lead to more appropriate therapeutic interventions by improving the ability to cope with these trauma related psychiatric sequelae.

Paragonimiasis is a parasitic infection that occurs following the ingestion of infectious Paragonimus metacercariae from crabs or crayfish. Pulmonary paragonimiasis is the most common clinical manifestation of this infection, but several ectopic paragonimiasis cases have also been reported. Among them, cases of subcutaneous paragonimiasis are rare, especially in children. We report a case of subcutaneous paragonimiasis of the right abdominal wall with pleural effusion with hepatic involvement and without abnormal pulmonary infiltration in a boy aged 2 years and 5 months. He had eaten soybean sauce-soaked freshwater crabs (kejang) 6 months prior to complaining of right abdominal wall distension. On evaluation, right pleural effusion without abnormal pulmonary infiltration was detected, as well as blood eosinophilia, an elevated serum IgE level, pleural fluid eosinophilia and a positive enzyme-linked immunosorbent assay that detected P. westermani antibody in the serum. Thoracentesis, praziquantel administration, and excision of subcutaneous lesions were performed. After treatment, the eosinophil count and serum IgE level were decreased, and the subcutaneous lesions did not recur. The frequency of paragonimiasis has decreased recently, but it is still prevalent in Korea. Paragonimiasis should be suspected if pleural fluid eosinophilia is associated with blood hypereosinophilia and a high level of serum IgE; however clinicians should obtain a thorough history of travel and food habits.

A lung hernia, defined as the protrusion of pulmonary tissue and pleural membranes through a defect in the thoracic wall, is a rare event. It can be congenital or acquired, and cervical, thoracic, or diaphragmatic in location. We report the rare occurrence of a congenital atraumatic lung herniation through the azygoesophageal recess. An 8 -month-old male infant, who was born at 3 5 weeks gestation, had a chronic cough. Chest radiography showed haziness at the right lower lobe of the lung (RLL). Chest computed tomography (CT) revealed herniation of the RLL through the azygoesophageal recess. If persistent unilateral haziness is observed on chest radiography, the possibility of lung herniation should be considered.

This technique in the conscious volunteers to study the neuromuscular blockade was described in which two different muscle relaxants of ED95X10(-1) in 20ml 0.9% saline were injected simultaneously into one arm and the contralateral arm below the occlusion site of circulation with tourniquet, and then two different neuromuscular blockades were compared following tourniquet released after 80% twitch depression. The benefits of this technique were obtained as following; 1) Simplicity, saving and safety from easily to set up and using low dose of muscle relaxant. 2) Expected results from pure effects of muscle relaxant without any drug interactions. 3) Time shortening of experimental study. 4) Saving time and experiments from simultaneously comparison of control with study group in one experiment. 5) The study of pure receptor binding with muscle relaxant, since a presumed plasma concentration of muscle relaxants is near or actually zero after release of the tourniquet when fresh blood had flushed the limb. Conclusively bilateral isolated forearm technique is elegant method to study the biophase binding interacted of relaxants and cholinerceptor.

Homer protein was identified based on its rapid induction in rat hippocampal granule cell neurons following excitatory synaptic activity. Although the presence of the Homer gene in the peripheral tissues has been observed in previous reports, the physiological function of the Homer protein in these tissues has not been noted. In this experiment, a Homer-2a cDNA fragment was successfully amplified by RTPCR in the involuting phase of human hemangioma but not in the human vascular malformation and normal vessel. After isolation of full Homer cDNA in a mouse liver cDNA library, E1-deleted recombinant adenovirus expressing the Homer protein (Adv.CMV.mHomer-2a) was constructed to determine its physiological function in peripheral tissues. Adv.CMV.mHomer2a, but not Adv.CMV.LacZ (recombinant adenovirus expressing beta-galactosidase), strongly inhibited the growth rate of HUVECs (human umbilical vein endothelial cells) probably via inducing apoptosis determined by acridine orange/ethidium bromide (AO/EB) staining methods. This study suggests that the Homer gene is present in human specimens in the involuting phase of hemangioma, and it might be involved in the growth control.

PURPOSE: To determine the clinical efficacy of percutaneous vertebroplasty in cases of painful and medically intractable osteoporotic vertebral compression fracture. MATERIALS AND METHODS: Ninety-eight patients (20 men and 78 women; mean age, 69 years) underwent 122 per-cutaneous vertebroplasty procedures for the treatment of osteoporotic vertical compression fracture. For the evaluation of bone mass, bone densitometry was performed in 45 patients, and to assess the recent evolution of the fracture, all 98 underwent MRI. Percutaneous vertebroplasty involves percutaneous transpedicular puncture of the involved vertebrae followed by the injection of a Polymethylmethacrylate(PMMA)-Barium mixture into the vertebral body. To assess leakage of the mixture into the epidural tissue, neural foramina, venous plexus and paravertebral tissue, we then immediately obtained a computerized tomographic (CT) scan, assessing the clinical efficacy of the procedure on the basis of time required for pain relief (defined as more than 60% reduction of initial pain), and time required for ambulation without significant pain. RESULTS: Percutaneous vertebroplasty was successful in all patients. Pain relief was accomplished within 1-5(mean, 1.8) days and early ambulation without significant pain was possible within 2 -15 (mean, 3.3) days. Post-procedural CT scanning revealed leakage of the PMMA-barium mixture into Paravertebral tissue(n=41), the paravertebral venous plexus (n=34) and epidural tissue (n=4). No neural foraminal leakage was identified, and no procedure-related complication requiring surgical treatment occurred. CONCLUSION: Percutaneous vertebroplasty is an effective new interventional procedure for the treatment of osteoporotic vertebral compression fracture. It relieves pain, provides early mobilization, and strengthens involved vertebral bodies.
