Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

Percutaneous cordotomy is a useful method for cancer pain management. Candidates for cervical cordotomy include those patients with unilateral cancer pain below the shoulder, with a life expectancy of less than 1 year, who can not be adequately treated by other less invasive methods. However, various complications can occur following a cordotomy, with the most serious being respiratory dysfunction. Herein, we report a case of transient respiratory dysfunction following a percutaneous cervical cordotomy.

Coccygodynia is a pain syndrome resulting from trauma, fractures, infection and tumor, and is usually amenable to conservative treatment. We present one case of coccygodynia that developed 2 days after percutaneous cordotomy done for pain control of cervix cancer unresponsive to conservative treatment which subsequently was treated with a caudal injection of lidocaine and triamcinolone. Caudal epidural steroid injection is less invasive and has less potential for complication than the neurosurgical interruption of the pain pathway.

Buerger's disease is a chronic occlusive arterial disease in which a non-arteriosclerotic lesion involves medium-sized arteries, veins, and nerves of the distal leg or arm. Sympathetic interruption is indicated to improve blood flow to the involved extremity, although sympathetic blockade can provide temporally relief of vasospasm and pain. Chemical or surgical sympathectomy has been performed for this purpose and intravenous regional sympathetic block(IRSB) is an alternative. Guanethidine or reserpine has been administered for IRSB. Intraarterial or intravenous systemic administration of prostaglandin E1(PGE1) has been recommended for the treatment of Buerger's disease. We used PGE1 for intravenous regional administration as an IRSB with results as good as that of intraarterial injection. The advantages of the method include that it is less expensive than systemic administration, less invasive than intra-arterial injection, and simple in technical application.

In spite of appropriate treatment of peri-implantitis, the peri-implant bone loss was keep going, the clinician should remove the osseointegrated implant. the conventional methods are like a extraction of natural teeth, and use of trephine drills. In these days, many exclusive instruments are invented by implant companies. these instruments can make easy, least invasive, less traumatic removal of osseointegrated implants. In generally peri-implant bone loss progress steadily less sign and symptoms that the patient do not want to remove their implants. However, the failure of dental implant is big burden to clinicians and also patients. In the dental implant treatment, there is no 'failure' but only is 'replacement' or 'change'.

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.

Of several techniques for closure of the patent ductus arteriosus, the less invasive surgical ranscatheter closure without thoracotomy(the Porstmann's procedure) may have a place between the Rashkind procedure and thoracotomy. We describe here a 68 year old woman with calcified patent ductus arteriosus which was successfully closed by the Porstmann's procedure.

Surgical resection is the most effective treatment in operable lung cancers. However, less invasive local treatments are being applicated to the patients having high surgical risk due to their poor general condition. Cryosurgery is known to be highly effective and safe in the treatment of liver and prostate cancers and it is also being applicated in the treatment of lung cancers, especially with the excision of tracheal mass and lung parenchymal cancers. In our hospital, we have tried a less Invasive method, the cryotherapy, to a patient who had a newly developed lung cancer at his right lower lobe after he had been treated with right upper lobe resection and left upper lobe resection due to bilateral lung cancels. After the treatment, he is being followed up at our out patient department for 2 years. Here, we present the method and result that have been applicated in this case.

Purpose: The digital artery perforator flap was recently introduced and has been proven to be useful for reconstruction of various finger defects. Short operative time, less invasive surgery, and reliable flap circulation are the major advantages of this flap. The authors presented the clinical cases of the digital artery perforator flap and compared them with the distant flaps within a hand (thenar and hypothenar flaps) to reveal their differences. Methods: From May of 2006 to February of 2009, the authors performed reconstructions of finger defects with the digital artery perforator flaps in 10 patients as with the distant flaps within hand in 9 patients (7 thenar and 2 hypothenar flaps). In these two groups of the patients, flap size, use of skin graft, length of stay in hospital, healing time, complications were reviewed retrospectively and compared with statistical analysis (Student's t-test). Results: All flaps survived completely. The mean size of the perforator flap was $0.9{\times}1.9\;cm$ and the mean distant flap within a hand was $1.9{\times}2.0\;cm$. The use of skin graft was reduced in the perforator group because the donor site of the flap was closed primarily. The hospitalization period and healing time also reduced significantly in the perforator group. Minor complications (partial flap loss) were noted in small percentages in both groups but resolved with conservative management. Mean follow-up period was about 6 weeks. Conclusion: The digital artery perforator flap was smaller than the distant flap but its reconstruction of finger defects was reliable and comparable to the conventional distant flaps within a hand. This flap would be not only an alternative method but very useful in the management of various finger defects, because of ease of operative technique, less invasive surgery, decreased need of skin graft, and shorter period of hospitalization and healing time.

The analysis of cow body parameters is important to provide some useful information fur cow management and cow evaluation. Present methods give many stresses to cows because they are invasive and constrain cow postures during measurement of body parameters. This study was conducted to develop the stereo vision system fur non-invasive analysis of cow body features. Body feature parameters of 16 heads at two farms(A, B) were measured using scales and nineteen stereo images of them with walking postures were captured under outdoor illumination. In this study, the camera calibration and inverse perspective transformation technique was established fer the stereo vision system. Two calibration results were presented for farm A and fm B, respectively because setup distances from camera to cow were 510 cm at farm A and 630cm at farm B. Calibration error values fer the stereo vision system were within 2 cm for farm A and less than 4.9 cm for farm B. Eleven feature points of cow body were extracted on stereo images interactively and five assistant points were determined by computer program. 3D world coordinates for these 15 points were calculated by computer program and also used for calculation of cow body parameters such as withers height. pelvic arch height. body length. slope body length. chest depth and chest width. Measured errors for body parameters were less than 10% for most cows. For a few cow. measured errors for slope body length and chest width were more than 10% due to searching errors fer their feature points at inside-body positions. Equation for chest girth estimated by chest depth and chest width was presented. Maximum of estimated error fur chest girth was within 10% of real values and mean value of estimated error was 8.2cm. The analysis of cow body parameters using stereo vision system were successful although body shape on the binocular stereo image was distorted due to cow movements.
