OBJECTIVE: To evaluate the cardiovascular response during head-out water immersion, underwater treadmill gait, and land treadmill gait in stroke patients. METHODS: Ten stroke patients were recruited for underwater and land treadmill gait sessions. Each session was 40 minutes long; 5 minutes for standing rest on land, 5 minutes for standing rest in water or on treadmill, 20 minutes for treadmill walking in water or on land, 5 minutes for standing rest in water or on treadmill, and 5 minutes for standing rest on land. Blood pressure (BP) and heart rate (HR) were measured during each session. In order to estimate the cardiovascular workload and myocardial oxygen demand, the rate pressure product (RPP) value was calculated by multiplying systolic BP (SBP) by HR. RESULTS: SBP, DBP, mean BP (mBP), and RPP decreased significantly after water immersion, but HR was unchanged. During underwater and land treadmill gait, SBP, mBP, DBP, RPP, and HR increased. However, the mean maximum increases in BP, HR and RPP of underwater treadmill walking were significantly lower than that of land treadmill walking. CONCLUSION: Stroke patients showed different cardiovascular responses during water immersion and underwater gait as opposed to standing and treadmill-walking on land. Water immersion and aquatic treadmill gait may reduce the workload of the cardiovascular system. This study suggested that underwater treadmill may be a safe and useful option for cardiovascular fitness and early ambulation in stroke rehabilitation.

OBJECTIVE: To investigate the effect of low-frequency repetitive transcranial magnetic stimulation (rTMS) and neuromuscular electrical stimulation (NMES) on post-stroke dysphagia. METHODS: Subacute (<3 months), unilateral hemispheric stroke patients with dysphagia were randomly assigned to the conventional dysphagia therapy (CDT), rTMS, or NMES groups. In rTMS group, rTMS was performed at 100% resting motor threshold with 1 Hz frequency for 20 minutes per session (5 days per week for 2 weeks). In NMES group, electrical stimulation was applied to the anterior neck for 30 minutes per session (5 days per week for 2 weeks). All three groups were given conventional dysphagia therapy for 4 weeks. We evaluated the functional dysphagia scale (FDS), pharyngeal transit time (PTT), the penetration-aspiration scale (PAS), and the American Speech-Language Hearing Association National Outcomes Measurement System (ASHA NOMS) swallowing scale at baseline, after 2 weeks, and after 4 weeks. RESULTS: Forty-seven patients completed the study; 15 in the CDT group, 14 in the rTMS group, and 18 in the NMES group. Mean changes in FDS and PAS for liquid during first 2 weeks in the rTMS and NMES groups were significantly higher than those in the CDT group, but no significant differences were found between the rTMS and NMES group. No significant difference in mean changes of FDS and PAS for semi-solid, PTT, and ASHA NOMS was observed among the three groups. CONCLUSION: These results indicated that both low-frequency rTMS and NMES could induce early recovery from dysphagia; therefore, they both could be useful therapeutic options for dysphagic stroke patients.

The purpose of this study was to determine shoulder pain and shoulder ultrasonographic findings in poliomyelitis Wheelchair Basketball (WB) players. Three physicians performed physical examinations and interviewed WB players about their shoulder pain by using Wheelchair User's Shoulder Pain Index (WUSPI), Performance-Corrected WUSPI (PC-WUSPI), and Shoulder Pain and Disability Index (SPADI). One physician performed shoulder ultrasonography on WB players. All confirmed their International Wheelchair Basketball Federation (IWBF) classifications through Korean Wheelchair Basketball Federation (KWBF). Seventeen men and 6 women players were enrolled in the study, with 46 shoulders evaluated. Nine players had unilateral lower extremity weakness and 14 players were bilateral weakness. Six players used wheelchair for daily living, and 17 players used wheelchair only when playing WB. They were 44.35+/-5.42 years old on average. They had played WB for 11.09+/-9.49 years and trained 8.69+/-3.83 hours a week. PC-WUSPI was significantly correlated with age (p=0.014). There were no significant differences between time spent playing WB, training time for WB, types of poliomyelitis involvement, their use of wheelchair, and WUSPI, PC-WUSPI and SPADI. Tendon tear prevalence was significantly different with training time for WB (p=0.021). Most common abnormal shoulder ultrasonographic findings were subscapularis and supraspinatus tendinopathy. Tendinopathy and tendon tear prevalence did not differ significantly with age, time spent playing WB, types of poliomyelitis, and the use of wheelchair. High prevalence of shoulder pain and rotator cuff pathology were found by physical and ultrasonographic examination in the poliomyelitis wheelchair basketball players. Rotator cuff injury prevention program are needed for prevent shoulder pain and rotator cuff pathology.

PURPOSE: Clinical features of Pancreatic Neuroendocrine Tumors (PETs) vary according to the hormone secreted and to the heredity of the tumors. Malignant PETs are common among nonfunctioning PETs (NFTs) whereas the majority of functioning PETs (FTs) are benign. Our goal was to determine the clinical features and prognosis of PETs stratified by the WHO classification scheme and AJCC-UICC 7TH TNM staging. METHODS: We selected for study 30 patients with PETs, including one case of nesidiolastosis, who presented at our clinic between April 1992 and June 2010. Clinicopathological features were studied retrospectively. PETs were classified as benign, uncertain malignant, well differentiated carcinoma, or poorly differentiated carcinomas by the WHO classification. For statistical analysis, Student's t-test, the Chi-square test, and the Kaplan-Meier method were utilized. RESULTS: Nine cases were FTs and twenty one cases were NFTs. The average size of the FTs was smaller than that of the NFTs (1.71 vs 4.33, p=0.04). The head of the pancreas was most commonly involved (33.3% of FTs; 47.6% of NFTs) but the locations of the tumors were not different. Insulinoma was the most common (66.7%, 6/9) among FTs. The incidence of malignant tumors was 33.3% and 55.0% among, respectively, FTs and NFTs. The 5-year disease-free survival rate of patients with benign PETs (FTs and NFTs), and of patients with functioning well-differentiated carcinomas was 100%. However, the 5-year disease-free survival rates of patients with nonfunctioning well- and poorly-differentiated carcinomas were 66.7% and 0%. CONCLUSION: Among patients with Pancreatic Neuroendocrine Tumors, malignant tumors are more common among NFTs than FTs. Poorly-differentiated carcinomas have a worse prognosis while all FTs regardless of their WHO classification fail to show any disease recurrence.

The proportion of male factor infertility due to quantitative and qualitative sperm disorders is approximately 50-60% in infertile couples. In IVF-ET, lower or failed fertilization of oocytes usually results from subnormal count of total motile sperms, but this may occur in infertile couples even with normal sperm count. It has been suggested that some functional defects in sperms are responsible for lower or failed fertilization. Routine semen analysis based on numerical background has limits for the assessment of fertilization capacity of sperm in infertile males, and the andrologic test for the prediction of fertilization capacity must be objective, repeatable, quick, economic, and easily applicable for the clinical settings. The purposes of this study were to develop the analysis method of strict morphology of sperm using the strict criteria as a simple, inexpensive and useful test of sperm fertilization capacity, to establish the normal fertile range and the cut-off value of strict morphology, and to evaluate the validity of strict morphology as a prognostic indicator of fertilization capacity in IVF-ET. In establishing the effectiveness of strict morphology of sperm, ROC curve was used. Among the various thresholds for the prediction of fertilizing ability, normal morphologic value 10.0 corresponding to the value with higher sensitivity and lesser false positive rates was determined as a cut-off value. Using this cut-off point, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of strict morphology for the prediction of fertilization capacity was 73.9%, 81.0%, 80.6%, and 72.7%, respectively. To evaluate the clinical validity of strict morphology as a prognostic indicator of fertilization capacity, this cut-off point was applied to 133 patients undergoing IVF-ET. For the prediction of fertilization rate >30% in IVF-ET, the sensitivity, specificity, PPV, and NPV was 77.3%, 77.8%, 87.2%, and 63.6%, respectively. In conclusion, the strict morphology of sperm is one of the most simple and useful test for the assessment of fertilization capacity of sperm and the prediction of IVF-ET outcomes in infertile couples.

PURPOSE: Female lung cancers have different clinical features and therapeutic results as compared to those of male lung cancers. The aim of this study was to analyze the differences of Korean men and women with lung cancer. MATERIALS AND METHODS: We re-analyzed the results of a national survey of lung cancer conducted by the Korean Association for the Study of Lung Cancer in 2005. RESULTS: Of the 8,788 patients, 2,124 (24.2%) were female. The mean age at the diagnosis was 62.5 years for the females and 64.8 years for the males and the difference was significant (p<0.001). An age <50 years was more frequent for the women than for the men (16.2% vs. 7.9%, respectively; p=0.001). The stages between genders were different for the patients with non-small cell carcinoma (NSCLC) (p<0.001), but not for the patients with small cell carcinoma. The overall survival time was longer for woman than that for the man (p<0.001). However, the male patients had longer survival for the smokers with adenocarcinoma and the smokers with squamous cell carcinoma. The never smoker female patients had a better survival time than did the smoking female patients, but the male patient' survival was not influenced by the smoking status. The stage-specific survival rates were better for the women at all stages of NSCLC (p<0.001). The women who received chemotherapy had a longer survival time did the men who received chemotherapy (p<0.001). CONCLUSION: Women with lung cancer were relatively overrepresented among the younger patients and they smoked less intensively, raising the question of gender- specific differences in the carcinogenesis of lung cancer. Over-representation of adenocarcinoma was observed in the women regardless of their smoking status. Women with lung cancer had a better prognosis than men; however, the smoking females showed the worst prognosis. Gender and the smoking status are clearly important factors in the therapeutic approach to lung cancer.

PURPOSE : Lung Cancer has been the leading cause of cancer deaths in South Korea since the year 2000, and its incidence continues to rise. Here we report the result of national survey of lung cancer conducted by Korean association for the study of lung cancer (KASLC). MATERIALS AND METHODS : A total of 8,788 lung cancer patients diagnosed in 2005 were registered using a web based case report form issued to hospitals equipped with more than 400 beds. RESULTS : The age distribution ranged from 11 to 105 years (64.7+/-0.7 years), 75.8% (6,664) of the patients were male and 28.9% of patients were never smokers. Subjective symptoms at the time of diagnosis included coughing (3,350 patients), dyspnea (2,105), chest pain (1,067), hemoptysis (805), weight loss (789), general weakness (498) and hoarseness (190), while 12% (1,015) of patients had no subjective symptoms. Of the carcinomas grouped into non-small cell lung carcinoma (NSCLC), adenocarcinoma including bronchoalveolar cell carcinoma (1.3%) was the most frequent (36.1%) histopathologic type, followed by squamous cell lung carcinoma (32.1%), large cell carcinoma (1.5%), unclassified non-small cell carcinoma (13.2%) and others (3.7%). In addition, 13.5% of all of the patients were afflicted with small cell lung carcinoma (SCLC). The stage at diagnosis was IA (7.3%), IB (10.2%), IIA (1.3%), IIB (6.1%), IIIA (12.8%), IIIB (21.6%), and IV (40.6%) in the NSCLC group. In SCLC group, 44.6% of the patients were in the limited stage, while 55.4% of the patients were in the extensive stage. The initial treatments included surgery (22.1%), radiation therapy (7.8%), chemo-radiation therapy (5.4%) and chemotherapy (38%), however, 26.6% of the patients were transferred or recorded to have supportive care only. Therefore we compared the outcomes of the Treatment Group (TG, 73.4%) and the Supportive Group (SG, 26.6%). The median survival time (MST) in months (m) was 28 (95% confidence interval 26.5~29.5 m). Multivariate analysis indicated that the independent prognostic factors for NSCLC were age, gender, ECOG PS score, stage, histopathologic type, and treatment or supportive care. In the SCLC group, age, PS score, stage, treatment or supportive care were significant prognostic factors. The TG group showed significantly superior survival when compared to the SG group, even in patients with stage IV disease and in patients that were >75 years old. CONCLUSION : Adenocarcinoma was found to be the most frequent histopathologic type, and active treatments were found to improve the survival of patients with lung cancer, even when they were in advanced stages or elderly

Background:
Because the etiologies of bronchiectasis and related diseases vary significantly among different regions and ethnicities, this study aimed to develop a diagnostic bundle for bronchiectasis in South Korea.
Methods:
A modified Delphi method was used to develop expert consensus statements on a diagnostic bundle for bronchiectasis in South Korea. Initial statements proposed by a core panel, based on international bronchiectasis guidelines, were discussed in an online meeting and two email surveys by a panel of experts (≥70% agreement).
Results:
The study involved 21 expert participants, and 30 statements regarding a diagnostic bundle for bronchiectasis were classified as recommended, conditional, or not recommended. The consensus statements of the expert panel were as follows: A standardized diagnostic bundle is useful in clinical practice; diagnostic tests for specific diseases, including immunodeficiency and allergic bronchopulmonary aspergillosis, are necessary when clinically suspected; initial diagnostic tests, including sputum microbiology and spirometry, are essential in all patients with bronchiectasis, and patients suspected with rare causes such as primary ciliary dyskinesia should be referred to specialized centers.
Conclusion
Based on this Delphi survey, expert consensus statements were generated including specific diagnostic, laboratory, microbiological, and pulmonary function tests required to manage patients with bronchiectasis in South Korea.
