Pulmonary paragonimiasis continues to be a diagnostically challenging parasitic disease, despite a drastically decreased prevalence in South Korea during the past decade. Pulmonary paragonimiasis is characterized by fever, chest pain, and chronic cough with hemoptysis. Numerous radiographic and computed tomographic findings including the presence of pneumothorax, pleural effusion, and parenchymal lesions such as nodular or infiltrative opacities have been reported. The clinical and radiological manifestations of paragonimiasis can resemble those of lung cancer, tuberculosis or a metastatic malignancy. Furthermore, this disease can mimic lung cancer as seen on $^{18}F$-fluorodeoxyglucose positron emission tomography (FDG-PET). We report a case of pulmonary paragonimiasis in a 48-year old man that presented with a solitary pulmonary nodule and was suspected as a lung cancer based on FDG-PET imaging.

Background: Atelectasis is an important prognostic factor that can cause pleuritic chest pain, coughing or dyspnea, and even may be a cause of death. In this study, we aimed to investigate the potential impact of atelectasis and PET parameters on survival and the relation between atelectasis and PET parameters. Materials and Methods: The study consisted of patients with lung cancer with or without atelectasis who underwent $^{18}F$-FDG PET/CT examination before receiving any treatment. $^{18}F$-FDG PET/CT derived parameters including tumor size, SUVmax, SUVmean, MTV, total lesion glycosis (TLG), SUV mean of atelectasis area, atelectasis volume, and histological and TNM stage were considered as potential prognostic factors for overall survival. Results: Fifty consecutive lung cancer patients (22 patients with atelectasis and 28 patients without atelectasis, median age of 65 years) were evaluated in the present study. There was no relationship between tumor size and presence or absence of atelectasis, nor between presence/absence of atelectasis and TLG of primary tumors. The overall one-year survival rate was 83% and median survival was 20 months (n=22) in the presence of atelectasis; the overall one-year survival rate was 65.7% (n=28) and median survival was 16 months (p=0.138) in the absence of atelectasis. With respect to PFS; the one-year survival rate of AT+ patients was 81.8% and median survival was 19 months; the one-year survival rate of AT-patients was 64.3% and median survival was 16 months (p=0.159). According to univariate analysis, MTV, TLG and tumor size were significant risk factors for PFS and OS (p<0.05). However, SUVmax was not a significant factor for PFS and OS (p>0.05). Conclusions: The present study suggested that total lesion glycolysis and metabolic tumor volume were important predictors of survival in lung cancer patients, in contrast to SUVmax. In addition, having a segmental lung atelectasis seems not to be a significant factor on survival.

Insufficiency fractures of the sacrum are relatively common and cause severe low back and buttock pain. Percutaneous vertebroplasty is effective for treating vertebral compression fractures. We present a case of percutaneous sacroplasty for the treatment of low back and buttock pain in a sacral insufficiency fracture. A 79-year-old male with non-small lung cancer presented with severe low back and buttock pain after series of radiation treatments. Preoperative MRI showed both a sacral ala and S2 metastatic insufficiency fracture. An epidural port was inserted for continuous morphine infusion and sacral nerve root blocks were performed. However, his pain did not diminish and we attempted percutaneous sacroplasty. Both sides of the sacroplasty were done with a fluoroscopy-guided technique with 1.7 ml and 2.3 ml of bone cement injected into the right and left sacral ala. Pain relief was significant and the patient was able to sit down 1 day after the procedure.

Over the past few years, video-assisted thoracic surgery [VATS] has been used increasingly for intrathoracic pathologic problems as a less invasive operative techniques. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. Using video-assisted operative thoracoscopy, we performed consecutive 150 operations on 148 patients during the initial 2 years of our experience from July 1992 with the following indications: pneumothorax [n=53], hyperhidrosis [n=29], mediastinal mass [n=23], pleural disease [n=13], diffuse parenchymal or interstitial lung disease [n=12], benign pulmonary nodule [n=7], metastatic lung mass [n=3], primary lung cancer [n=3], bronchiectasis [n=2], malignant pericardial effusion [n=2], endobronchial tuberculosis [n=1], esophageal achalasia [n=1], and pulmonary parenchymal foreign body [n=1]. There were no death, and overall complicaton rate was 24.0%[n=36]. The most prevalent complication was persistent air leakage [longer than 5 days] in 14 cases [9.3%]. Persistent pleural effusion [longer than 5 days] occurred in 6 cases [4.0%]. Six patients were converted to an open thoracotomy because of inability to control the operative bleeding [n=3], failed adhesiolysis in bronchiectasis [n=2], and radical excision of an lung cancer [n=1]. Pneumothorax recurred in 3 cases[2.0%]. Other complications were Horner`s syndrome, diaphragm tears, temporary phrenic nerve palsy, hoarseness, subsegmental atelectasis, transient respiratory difficulty, and esophageal mucosal tear. The advantages of this minimally traumatizing operative technique lie in improved visualization, decreased pain, shortened hospital stay, and less postoperative morbidity. The indications of VATS has been extended increasingly to intrathoracic pathologies, but its role in the managements of primary lung cancer and esophageal disease remains to be defined.

In this case, we report a case of Soeumin rectal cancer patient who was mistreated with herb medication. This patient was 72 years old female diagnosed rectal cancer stage IV with multiple liver, lung, and LN metastases. She administered our cancer center in Sep. 2011 for cancer treatment, we diagnosed this patient as Taeyangin at first, and treated with Mihuedungsikjang-tang. After 1 week, she complained upper abdominal discomfort, severe abdominal pain, nausea and sweating. Considering several symptoms and conditions, the change of symptoms seemed to a adverse events caused by mistreatment. We re-diagnosed this patient as Soeumin, and treated with Soeumin herbal medication, Baekhaoleejung-tang(白何烏理中湯) and Hyangsayangyi-tang(香砂養胃湯). Several symptoms including abdominal pain were improved 2 weeks later. Therefore, we report this case as a reference that Soeumin misdiagnosed as Taeyangin and the improvement of adverse symptoms.

Objective : A new point of view on the chronic back pain proposed which is, named neuropathic back pain[NBP]. Some proposed a certain pain scale as an useful diagnostic tool. Before scientific verification, some doctors prescribed a new anticonvulsant for the NBP. We investigated diagnostic tools for NBP by a review of the literature. Methods : A comprehensive computer search of the English literature concerning neuropathic low back pain was performed using the key words such as neuropathic back pain and diagnosis in the PubMed. Results : In 1998, the term NBP was first used in a patient with lung cancer. In the English literature, there were two diagnostic methods for the NBP, Neuropathic pain scale[NPS] and a pharmacological test. NPS is a pain questionnaire, which depends on the patients' subjective reports on the given questions, such as 'how hot is your pain feel'. By the pharmacological test, NBP was defined as 50% or more decrease of pain on intravenous lidocaine and on local anesthetic epidurally. It also depends on the patients' subjective response to the therapy. Conclusion : There were still no reliable objective diagnostic criteria for the NBP. It seems to be better to reserve the new anticonvulsants for the NBP till scientific approval.

Vertical axillary muscle sparing thoracotomy is newly appeared and excellent alternative method of standard posterolateral thoracotomy.It has many advantages compared to standard posterolateral thoracotomy , less postoperative pain, well preserved thoracic muscle strength, full range of motion of the shoulder girdle and attractive cosmetic results. We performed vertical axillary muscle sparing thoracotomy in 36 patients from November 1993 to July 1994. The ages of the patients ranged from 6 months to 71 years[mean 45.1 years , and the patients consisted of 20 males and 16 females.The preoperative diagnosis were as follows : lung cancer in 17 patients, tbc destroyed lung in 7, bronchiectasis in 3, bullous emphysema in 3 and the others are mediastinal tumor, bronchogenic cyst, lung abscess, empyema, esophageal diverticulum, and CCAM [congenital cystic adenomatoid malformation . The operative procedures were as follows : lobectomy and bilobectomy in 16 patients, segmentectomy in 4, wedge resection in 3, penumonectomy in 7, and the others were open biopsy, lobectomy with diaphragm excision, sleeve right upper lobectomy, decortication, mediastinal mass excision, and esophageal diverticulectomy. We had 6 complications : postoperative bleeding in 2 cases, operative wound infection, arrrhythmia[atrial fibrillation , Horner`s syndrome, hoarseness. The subcutaneous seroma occurred in 4 cases but did not require drainage and relieved within 4 weeks spontaneously. We concluded that vertical axillary muscle sparing thoracotomy could be done in most of all thoracic surgery with safety. Comparing to standard posterolateral thoracotomy vertical axillary muscle sparing thoracotomy has many advantages such as less postoperative pain, well preserved muscle strengths and good cosmetic results.

A gastrointestinal metastasis from lung cancer is rare and is quite often found during an autopsy. A 58-year-old man was admitted with left upper back pain and a mass in the left upper lobe on the chest radiograph. The transbronchial lung biopsy revealed an adenocarcinoma of the lung. A gastroduodenoscopy was carried out to evaluate the indigestion and epigastric discomfort. The duodenofibroscopy revealed bulging mucosa on the minor papilla of the duodenum. A metastasis to the duodenum from an adenocarcinoma of the lung was diagnosed by a duodenofibroscopic biopsy of the bulging lesion. We report this rare case of an adenocarcinoma of lung with a metastasis to the duodenum.

A radiation recall reaction refers to an inflammatory reaction at previous irradiated areas subsequent to the administration of a variety of pharmacological agents. The skin is the major site of radiation recall reactons with the muscle and internal organs being less commonly affected. These reactions usually occur days to weeks after exposure to the causative agents. We report a case of gemcitabine-induced radiation recall dermato-myositis the developed in a female patient with a metastatic non-small cell lung cancer. She had received a palliative radiation therapy of 3900 cGy to the metastatic lesion on the femur shaft prior to chemotherapy. The pain, swelling and erythema of the left thigh resolved after the cessation of gemcitabine and the use of a systemic steroid.

Objective : Primary treatment of spinal metastasis has been external beam radiotherapy. Recent advance of technology enables radiosurgery to be extended to extracranial lesions. The purpose of this study was to determine the clinical effectiveness and safety of stereotactic radiosurgery using Cyberknife in spinal metastasis. Methods : From June, 2002 to December, 2007, 129 patients with 167 spinal metastases were treated with Cyberknife. Most of the patients (94%) presented with pain and nine patients suffered from motor deficits. Twelve patients were asymptomatic. Fifty-three patients (32%) had previous radiation therapy. Using Cyberknife, 16-39 Gy in 1-5 fractions were delivered to spinal metastatic lesions. Radiation dose was not different regarding the tumor pathology or tumor volume. Results : After six months follow-up, patient evaluation was possible in 108 lesions. Among them, significant pain relief was seen in 98 lesions (91%). Radiological data were obtained in 83 lesions. The mass size was decreased or stable in 75 lesions and increased in eight lesions. Radiological control failure cases were hepatocellular carcinoma (5 cases), lung cancer (1 case), breast cancer (1 case) and renal cell carcinoma (1 case). Treatment-related radiation injury was not detected. Conclusion : Cyberknife radiosurgery is clinically effective and safe for spinal metastases. It is true even in previously irradiated patients. Compared to conventional radiation therapy, Cyberknife shows higher pain control rate and its treatment process is more convenient for patients. Thus, it can be regarded as a primary treatment modality for spinal metastases.
