Objective: Giant invasive pituitary adenoma looks histologically benign, but these tumors have an aggressive clinical course. The authors review 10 cases and discuss the results obtained and the strategy to use for the management of giant invasive pituitary adenoma. Methods: Out of a series of 155 pituitary adenomas treated surgically between 1994 and 2002, ten patients with giant invasive pituitary adenoma were selected and their clinical problems, radiologic findings, extent and invasiveness, hormonal and histologic findings and surgical results were analyzed retrospectively. Results: There were 4 male and 6 female patients, with an average age of 47 years and an average follow-up period of 42 months. The average size of tumor was 50.7mm. These tumors revealed severe invasions into surrounding structures. 8 patients underwent transsphenoidal approach(TSA) operations, 1 patient with transcranial operation and 1 patient with combined TSA and transcranial operation. In all cases, subtotal resection was performed. The histologic findings were 2 prolactinomas and 3 hormonal non-function adenomas. The therapies administered after surgical removal consisted of conventional fractionated radiotherapy (2 patients), treatment with dopamine agonists to control hyperprolactinemia (2 patients), and treatment with hormone replacement (2 patients). Conclusion: Giant invasive pituitary adenomas are characterized by different forms of expansion and invasiveness and variable clinical problems. Because of their aggressive expansion and invasiveness, there are many different strategies which can be considered for their management. The authors obtain good results by choosing conservative surgical removal and multidisciplinary treatments with serial radiological and hormonal follow-up.

Radioiodide uptake in thyroid follicular epithelial cells, mediated by a plasma membrane transporter, sodium iodide symporter (NIS), provides a first step mechanism for thyroid cancer detection by radioiodide injection and effective radioiodide treatment for patients with invasive, recurrent, and/or metastatic thyroid cancers after total thyroidectomy. NIS gene transfer to tumor cells may significantly and specifically enhance internal radioactive accumulation of tumors following radioiodide administration, and result in better tumor control. NIS gene transfers have been successfully performed in a variety of tumor animal models by either plasmid-mediated transfection or virus (adenovirus or retrovirus)-mediated gene delivery. These animal models include nude mice xenografted with human melanoma, glioma, breast cancer or prostate cancer, rats with subcutaneous thyroid tumor implantation, as well as the rat intracranial glioma model. In these animal models, non-invasive imaging of in vivo tumors by gamma camera scintigraphy after radioiodide or technetium injection has been performed successfully, suggesting that the NIS can serve as an imaging reporter gene for gene therapy trials. In addition, the tumor killing effects of I-131, ReO4-188 and At-211 after NIS gene transfer have been demonstrated in in vitro clonogenic assays and in vivo radioiodide therapy studies, suggesting that NIS gene can also serve as a therapeutic agent when combined with radioiodide injection. Better NIS-mediated imaging and tumor treatment by radioiodide requires a more efficient and specific system of gene delivery with better retention of radioiodide in tumor. Results thus far are, however, promising, and suggest that NIS gene transfer followed by radioiodide treatment will allow non-invasive in vivo imaging to assess the outcome of gene therapy and provide a therapeutic strategy for a variety of human diseases.

Rupture of aortic is for the most part a terminal disorder and requires prompt and aggressive treatment. Most of the patients who develop this condition outside the hospital die before appropriate therapy can be instituted. Thus prompt treatment, sometimes innovative, resulted in a highly significant survival rate. We experionced 21 aortic rupture due to mycotic aneurysm and another 3 due to chest trauma. Operation was done in 11 cases, and mortality was 3 of 11 cases. In another 10 cases, operation was not performed and all of them were expired. We confirmed diagnosis using only non invasive technic as ultrasonogram and computed tomography and invasive technic like aniography was absolutely avoided. Preoperative management was aimed to lower blood pressure for the purpose of preventing srcondary bleeding, and operantions erer porformed promptly if possible.

In this paper, we present an intensive patient monitoring service through the Internet, which enables medical doctors to watch their patients in a remote site, to monitor their vital signs and to give them some advices for first-aid treatment. The service consists of three service objects: Monitoring Information Service(MIS), Vital Sign Monitoring Service(VSMS) and Multimedia Consulting (MCS). Through the MIS, medical doctors can get information about the patients currently under monitoring, including their names, ages, genders, symptoms, current main complaints and current locations. The VSMS enables medical doctors to monitor in real-time patients' vital signs such as electrocardiogram (ECG), respiration, temperature, blood oxygen saturation (SpO$_{2}$), invasive blood pressure (IBP), and non-invasive blood pressure (NIBP). It also generates alarms when the patients are likely to be in a critical situation. The MCS provides a real-time multimedia desktop conferencing facility for watching patients and instructing attendants to administer some first-aid treatment. We carried out some experiments according to two different scenarios. The intensive patient monitoring service was functioning well in a 100Base-T Ethernet LAN environment.

Background: Non-invasive painless signaling therapy (NPST) is an electro-cutaneous treatment that converts endogenous pain information into synthetic non-pain information. This study explored whether pain improvement by NPST in failed back surgery syndrome (FBSS) patients is related to cerebral modulation. Methods: Electroencephalography (EEG) analysis was performed in 11 patients with FBSS. Subjects received daily NPST for 5 days. Before the first treatment, patients completed the Brief Pain Inventory (BPI) and Beck Depression Inventory and underwent baseline EEG. After the final treatment, they responded again to the BPI, reported the percent pain improvement (PPI), and then underwent post-treatment EEG. If the PPI grade was zero, they were assigned to the ineffective group, while all others were assigned to the effective group. We used standardized low-resolution brain electromagnetic tomography (sLORETA) to explore the EEG current-source distribution (CSD) associated with pain improvement by NPST. Results: The 11 participants had a median age of 67.0 years, and 63.6% were female. The sLORETA images revealed a beta-2 CSD increment in 12 voxels of the right anterior cingulate gyrus (ACG) and the right medial frontal area. The point of maximal CSD changes was in the right ACG. The alpha band CSD increased in 2 voxels of the left transverse gyrus. Conclusions: Pain improvement by NPST in FBSS patients was associated with increased cerebral activity, mainly in the right ACG. The change in afferent information induced by NPST seems to be associated with cerebral pain perception.

Gunshot-induced chest trauma is exceedingly rare among civilians in South Korea due to strong firearm control policies. In contrast to military reports emphasizing the use of emergent open thoracotomy to increase chances of survival, most penetrating non-cardiac injuries in civilian settings are managed conservatively, such as through chest tube insertion, as they typically result from lower-energy bullets. However, early surgical intervention for penetrating gunshot wounds can help reduce delayed fatalities caused by septic complications from pneumonia or empyema. The advent of minimally invasive thoracic surgery has provided cost-effective and relatively non-invasive treatment options, aided in the prevention of potential complications from undrained hematomas, and facilitated functional recovery and reintegration into society. We successfully treated a patient with a penetrating gunshot wound to the chest using video-assisted thoracoscopic surgery.

Purpose: Several markers for eosinophilic inflammation have been proposed to predict response to asthma treatment. However, definitive criteria for treatment decisions have not yet been established. We investigate a potentially useful relatively non-invasive biomarker, eosinophil-derived neurotoxin (EDN), to predict favorable responses to budesonide or montelukast, common treatment for children with asthma. Methods: Young children (1 to 6 years old) were enrolled in this randomized, parallel, 2-group, open-label trial. Criteria for eligibility included: 1) being symptomatic during the run-in period; and 2) having a serum EDN (sEDN) level ${\geq}53ng/mL$, with positive specific immunoglobulin E to house dust mite. Eligible patients were randomly placed into 2 groups: the BIS group received budesonide inhalation suspension (BIS) 0.5 mg once daily; the MONT group received montelukast 4 mg once daily. Ineligible patients were invited to receive montelukast 4 mg once daily (OBS group). Treatment period was 12 weeks. Results: Asthma control days increased significantly in the BIS and MONT groups (P < 0.000) over the 12-week study period. There was no significant change in sEDN in the BIS group but there was a significant decrease in the MONT group (P < 0.000). Patients in the OBS group with high EDN levels (> 53 ng/mL) showed a significant decrease due to MONT treatment (P = 0.023). Rescue medication usage significantly decreased in the BIS and MONT groups (P < 0.000). Conclusions: EDN is a useful relatively non-invasive biomarker for predicting responses to montelukast and budesonide treatment of preschool children with beta2-agonist responsive recurrent wheeze and multiple-trigger wheeze (Trial registry at UMIN Clinical Trials Registry, UMIN000008335).

Objectives: Loss of lumbar lordosis causing pain and curvature of the vertebral skeleton to one side is a relatively uncommon disease. To our knowledge, successful treatment of loss of lumbar lordosis with any potentized homeopathic drug diluted above Avogadro's limit (that is, above a potency of 12C) has not been documented so far. In this communication, we intend to document a relatively rare case of loss of lumbar lordosis with osteophytic lippings, disc desiccation, and protrusion, causing a narrowing of secondary spinal canal and a bilateral neural foramina, leading to vertebral column curvature with acute pain in an adolescent boy. Methods: The patient had undergone treatment with orthodox Western medicines, but did not get any relief from, or cure of, the ailment; finally, surgery was recommended. The patient's family brought the patient to the Khuda-Bukhsh Homeopathic Benevolent Foundation where a charitable clinic is run every Friday with the active participation of four qualified homeopathic doctors. A holistic method of homeopathic treatment was adopted by taking into consideration all symptoms and selecting the proper remedy by consulting the homeopathic repertory, mainly of Kent. Results: The symptoms were effectively treated with different potencies of a single homeopathic drug, Calcarea phos. X-ray and magnetic resonance imaging (MRI) supported recovery and a change in the skeletal curvature that was accompanied by removal of pain and other acute symptoms of the ailment. Conclusion: Homeopathy can be a safe, much less expensive, non-invasive, and viable alternative for the treatment of such cases.

Objectives : The purpose of this study is to analyze an effect of medical Qigong therapy using Dong Chu Chim (DCC) which was invented by "Dongchu Han Medicine Institute", by measuring HRV. We compared effects of DCC with non-treatment, filiform acupuncture and filiform acupuncture with natural abdominal breathing. Methods : 1. The authors stimulated Nogung (PC8) of 26 normal adults by using DCC or filiform acupuncture in turn. 2. The natural abdominal breathing has been carried comfortably with consciousness in the lower abdomen. 3. HRV was measured for 5 minutes, three times (pre-treatment, during-treatment and post-treatment). Results and Conclusions : From this study, it seems that the stimulus of DCC, filiform acupuncture, filiform acupuncture with natural abdominal breathing can all affect the autonomic nervous system and control the balance of that. But there were not significant differences between these stimulus groups and the non-treatment group. Therefore, we suggest additional studies about the effect of DCC in the future.

대뇌혈류를 증가 시키는 수술은 뇌경색의 치료방법중 하나이다. 그러나 수술과 같은 침습적인 방법은 환자에게 수술 후유증 또는 부작용을 부담하게 한다. 이러한 침습적인 방법을 보완하기 위해 사람의 혈압을 이용해, 사지에 압박을 가하여 대뇌 혈류를 증가 시키는 비 침습적인 장치도 등장하였다. 그러나 속도와 정확성이 떨어지는 문제점이 제기되었다. 본 논문에서는, 정확한 측정과 측정하는 데에 걸리는 시간을 기존의 장치보다 개선하기 위해, Blood Oxygen Level Sensor를 이용하여, 양팔에 압력을 주면서 각 팔의 Perfusion Index를 측정하여, Perfusion Index가 일정 값 이하로 떨어지는 순간의 75% 압력을 팔에 가하고, 다리에는 팔에서 구해진 압력 값을 이용해 계산하여 얻은 압력을 가한다. 기존의 혈압 측정식 대뇌혈류증가 장치와 같이, 혈류량을 20%이상 증가시킬 수 있고, 또한 측정 시간도 단축한 결과를 얻어 뇌경색 환자에게 선택적으로 사용할 수 있다.
