PURPOSE: Data on the efficacy of olanzapine in patients receiving moderately emetogenic chemotherapy (MEC) are limited. This study aimed to evaluate and compare the efficacy of olanzapine versus placebo in controlling nausea and vomiting in patients receiving MEC. MATERIALS AND METHODS: We conducted a randomized, double-blind, placebo-controlled study to determine whether olanzapine can reduce the frequency of chemotherapy-induced nausea and vomiting (CINV) and improve the quality of life (QOL) in patients receiving palonosetron and dexamethasone as prophylaxis for MEC-induced nausea and vomiting. The primary end point was complete response for the acute phase (0-24 hours after chemotherapy). The secondary end points were complete response for the delayed (24-120 hours) and overall phase (0-120 hours), proportion of significant nausea (visual analogue scale ≥ 25 mm), use ofrescue medications, and effect on QOL. RESULTS: Fifty-six patients were randomized to the olanzapine (n=29) and placebo (n=27) groups. Complete response rates were not significantly different between the olanzapine and placebo groups in the acute (96.5% vs. 88.0%, p=0.326), delayed (69.0% vs. 48.0%, p=0.118), and overall phases (69.0% vs. 48.0%, p=0.118). However, the percentage of patients with significant nausea (17.2% vs. 44.0%, p=0.032) and the use of rescue medications (0.03±0.19 vs. 1.88±2.88, p=0.002) were lower in the olanzapine group than in the placebo. Furthermore, the olanzapine group demonstrated better QOL (p=0.015). CONCLUSION: Olanzapine combined with palonosetron and dexamethasone significantly improved QOL and vomiting control among previously untreated patients receiving MEC, although the efficacy was limited to the reduction of the frequency of CINV.

OBJECTIVES: Since pain in cancer patients is an important factor that greatly affects the quality of life and prognosis, many attempts have been actively made to reduce the pain. Despite continuous effort on reducing pain after Endoscopic submucosal dissection (ESD), research has not been done on psychological factors as much as on biological factors affecting pain. The objective of this study is to investigate the psychological factors affecting postoperative pain in gastric tumor patients who underwent gastric ESD. METHODS: 91 gastric tumor patients who visited National Health Service Ilsan Hospital in Korean between May 2015 and June 2016, and received ESD were evaluated. Baseline characteristics including sociodemographic factors, anxiety, depression, and resilience were evaluated before the procedure. Multivariate logistic regression was done to analyze factors affecting postoperative pain. RESULTS: The group with high postoperative pain showed lower alcohol consumption and higher depressive symptom scores than the group with low postoperative pain. Also, the group with high postoperative pain showed lower total resilience score with lower subtotal scores in self-control and positive item. Multivariate logistic regression analysis of the postoperative pain showed that patients with lower score in self-control of resilience [odd ratio (OR), 0.911 ; 95% CI, 0.854–0.971, p=0.004) reported more pain after ESD. CONCLUSIONS: This study showed that patients with lower self-control ability of resilience felt more pain after ESD. Among the psychological factors evaluated in this study, resilience of an individual seems to have effect on pain.

“Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” is the 3rd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 2nd edition published in 2014. Forty-two specialists in stroke rehabilitation from 21 universities and 4 rehabilitation hospitals and 4 consultants participated in this update. The purpose of this CPG is to provide optimum practical guidelines for stroke rehabilitation teams to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. The recent two CPGs from Canada (2015) and USA (2016) and articles that were published following the 2nd edition were used to develop this 3rd edition of CPG for stroke rehabilitation in Korea. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.

Achalasia is a primary esophageal motility disorder characterized by functional obstruction of the distal esophagus and subsequent dilation of the proximal esophagus. The most common symptoms in children and adolescents are vomiting, progressive dysphagia, weight loss, recurrent pneumonia, nocturnal cough, and chest pain. A girl who had been diagnosed with asthma poorly responsive to inhaled steroids until age 17, presented at the hospital with cough, sputum, and fever. Finally, she was diagnosed with achalasia and underwent esophageal balloon dilatation, which relieved her GI and pulmonary symptoms. We report this case with a literature review.

PURPOSE: Recent literature has shown that lymph node ratio is superior to the absolute number of metastatic lymph nodes in predicting the prognosis in several malignances other than colorectal cancer. The aim of this study was to evaluate the prognostic significance of the lymph node ratio (LNR) in patients with stage III colorectal cancer. METHODS: We included 186 stage III colorectal cancer patients who underwent a curative resection over a 10-year period in one hospital. The cutoff point of LNR was chosen as 0.07 because there was significant survival difference at that LNR. The Kaplan-Meier and the Cox proportional hazard models were used to evaluate the prognostic effect according to LNR. RESULTS: There was statistically significant longer overall survival in the group of LNR > 0.07 than in the group of LNR < or = 7 (P = 0.008). Especially, there was a survival difference for the N1 patients group (LN < 4) according to LNR (5-year survival of N1 patients was lower in the group of LNR > 0.07, P = 0.025), but there was no survival difference for the N2 group (4 > or = LN) according to LNR. The multivariate analysis showed that the LNR is an independent prognostic factor. CONCLUSIONS: LNR can be considered as a more accurate and potent modality for prognostic stratifications in patients with stage III colorectal cancer.

Chemical pneumonitis is defined as lung irritation caused by inhalation of substances toxic to the lungs. Acute chemical pneumonitis causes swelling of the lung tissue, movement of fluid into the air spaces in the lung, and a decreased ability to absorb oxygen and eliminate carbon dioxide. Teflon (polytetrafluoroethylene) is a commonly used synthetic fiber or insulator. To our knowledge, chemical pneumonitis and acute respiratory failure induced by Teflon inhalation has not been previously reported in Korea. We experienced a 44-year-old patient who had a cough and dyspnea that were aggravated 10 h after smoking tobacco wet by Teflon for 5 min at his workplace. Upon arrival at the emergency room, his blood pressure was low and his arterial blood gas analysis revealed hypoxemia. A chest radiograph showed diffuse haziness on both mid- to-lower lung fields. Following treatment by conservative therapy, including oxygen supply and steroid use, his condition was relatively good and his chest radiograph normalized.

Pulmonary tuberculosis has intermediate prevalence in Korea. It is known that tuberculosis infection predominantly involves the upper lobes, based on the fact that multiplication of Mycobacterium tuberculosis is favored in areas with decreased pulmonary blood flow, impaired lymphatic drainage, and high oxygen tension. We report this case of a 40-year-old man who was brought to our hospital with hemoptysis and dyspnea. Prior to admission, the patient had been in a bedridden state for 15 years due to an injury of the cervical spine 4~5. A 3-Dimensional computed tomography showed predominantly longitudinal distribution of centrilobular nodules along the anterior chest wall, in the left lung. MTB-PCR and AFB culture of bronchial washing fluid revealed pulmonary tuberculosis. This case shows that long-standing supine posture and decreased motion of the anterior chest wall may change the distribution of preferential infection site of Mycobacterium tuberculosis in the lung, resulting in a ventral predominance of tuberculosis infection in the quadriplegic patient.

Papillary thyroid carcinoma is the most prevalent type of thyroid cancer. Metastasis of this carcinoma commonly occurs in the lung and has been reported to present 5 to 30 years after the initial diagnosis of thyroid cancer. Pleural effusion can mask this metastatic spread. In patients with pleural effusion, laboratory measurement of the adenosine deaminase (ADA) level in the pleural fluid can be effective in identifying and ranking pulmonary metastasis in the differential diagnosis. A 70-year-old female patient visited our hospital with dyspnea. She presented with a considerable amount of pleural effusion. A pleural biopsy was performed and the Ziehl-Neelsen stains revealed a few acid-fast bacilli, but the ADA level in the pleural fluid was 2.4 IU/L. After drainage of the pleural effusions, we discovered pulmonary nodules by computed tomography (CT), which were later diagnosed through histologic examination as pulmonary metastasis from papillary thyroid carcinoma. We report this case.

PURPOSE: To assess the usefulness of the Hounsfield number, measured by a non-contrast enhanced pelvic CT, after a uterine artery embolization as an index of the successful outcome of a uterine fibroid embolization (UFE). MATERIALS AND METHODS: The study subjects included 15 women (age range: 28-49 years, mean age: 36.4 years) diagnosed with symptomatic uterine myomas and seen from March 2003 to August 2005. A non-contrast enhanced pelvic CT scan was performed six hours after a uterine artery embolization. The global and maximal CT numbers were measured for each myoma. In addition, a pelvic MRI was performed to measure the volume of each myoma prior to and 6 months after the UFE. The relationship between fibroid volume reduction and the global CT number were prospectively analysed. RESULTS: The mean global CT number was 91.25 HU in Group I and 40.8 HU in Group II. Further, the mean fibroid volume reduction rate was 73% in Group I and 10% in Group II (p < 0.05). CONCLUSION: The global CT number measured by a non-contrast enhanced pelvic CT is a useful predictive factor of a successful uterine fibroid embolization.
