PURPOSE: The purpose of this study is to examine the clinical applicability of stress radiography in patients presenting with shoulder instability. MATERIALS AND METHODS: Fifty-six patients diagnosed with shoulder instability and 20 healthy volunteers participated in the study. Degree of displacement of the humeral head as measured on stress radiography using a Telos GA-IIE device was compared with the results of the physical examinations. Four types of stress radiography were captured while applying 15 daN of force anteriorly (AER0 and AER60) and posteriorly (PER0 and PER60) at two different positions: (1) 90° of abduction combined with 0° of external rotation, and (2) 90° of abduction combined with 60° of external rotation. RESULTS: The degree of displacement of affected shoulders of 44 patients showed significantly larger displacement than normal shoulders (p<0.05), and the comparison between 56 affected shoulders of the patients and 40 normal shoulders of the volunteers showed significantly larger displacement only in PER0 and PER60 of the patients (p<0.05). Among the four radiographs of affected shoulders, AER60 showed significantly less displacement (p=0.046). The anterior drawer test under anesthesia of 16 patients who underwent surgery for anterior instability showed positive correlation with AER0 (Spearman's rho=0.56, p<0.024). Significantly larger anterior displacement of the load and shift test was observed in the subgroup with anterior displacement more than 3 mm (p=0.028), and higher positive frequency of the Kim's test was observed in the subgroup with posterior displacement more than 3 mm (p=0.005). CONCLUSION: Stress radiography using a Telos GA-IIE device could discriminate the affected shoulder. Although it could not replace individual physical examinations, the degree of displacement correlates with some physical examinations for shoulder instability.

PURPOSE: A phase II study of vinorelbine and ifosfamide combination chemotherapy in patients with advanced or recurrent non-small cell lung cancer (NSCLC) was conducted to assess response rate, response duration, and toxicites. MATERIALS AND METHODS: Patients with advanced NSCLC who had no prior systemic chemotherapy were eligible. They have no central nervous system metastasis and recurrent or progressive disease after surgery or radiotherapy. Each cycle consisted of vinorelbine 25 mg/m' i.v. days 1 & 8, and ifosfamide 2 g/m i.v. days 1, 2 & 3 with Mesna and treatments were repeated every 21 days. RESULTS: Forty patients with advanced or recurrent NSCLC were treated at multi center between March, 1997 and March, 1998. Six patients were not evaluable because five patients refused therapy after the first course and one patient was protocol violation. Of 34 evaluable patients, objective responses were seen in 11 (32.4%) patients (CR 0%, PR 32.4%). The median duration of response was 16.4 weeks. The median overall survival was 9.5 months. The toicities of this regimen were acceptable without treatment related toxic death. CONCLUSION: We concluded that combination regimen of vinorelbine and ifosfamide was effective and tolerable in the treatment of advanced non-small cell lung cancer.

Objective: This study was designed to verify the effectiveness of capnography and ultrasound for confirmation of the location of the nasogastric tube (NGT) in the emergency room (ER). Methods: In this prospective single-blinded study, carried out on 137 patients over 19 years of age, the NGT location was confirmed by capnography in 63 patients and by ultrasound in 74 patients. The capnography and ultrasound scans were performed in random order, while auscultation was performed and chest X-rays were taken for all patients. Capnography was performed by checking the end-tidal carbon dioxide (ETCO2) level and the wave form after inserting the NGT. An ultrasound scan was conducted on the neck, gastroesophageal junction and stomach. The X-ray results were interpreted by a doctor who had not inserted the NGT. Results: The sensitivity and specificity of auscultation were 98.43% and 10%, respectively. After 30 cm of NGT was inserted ETCO2 was measured through the capnography, and was found to be ranging from 0-23. When the capnography showed an ETCO2 value of less than 4, the tube was considered to be inserted in the stomach. In such a case, the specificity was 100%, but the sensitivity was only 46.43%. The sensitivity and specificity of the ultrasound were 92.96% and 66.67%, respectively. In addition, the positive predictive value was confirmed to be 100% and 98.51% when using capnography and ultrasound, respectively. Conclusion When the NGT is inserted in the ER, it is possible to use ultrasound and capnography for confirmation of its location. However, in some patients, when neither method can confirm the location, a chest X-ray will still be needed.

Inflammatory acquired Blaschko-linear dermatoses (IABLD) are a continuous concept involving diseases such as lichen striatus, blaschkitis, and atopic dermatitis. However, atopic dermatitis that showed increase in severity along Blaschko lines is rarely reported on its own. Herein, we report a rare case of atopic dermatitis with secondary prurigo nodularis along Blaschko lines, which may be valuable in broadening the concept of IABLD. A 28-year-old male presented with multiple, pruritic, brownish nodules on the left lower extremity along Blaschko lines for 3 to 4 years. The patient had atopic dermatitis since childhood. Histopathologic findings revealed compact orthohyperkeratosis, hypergranulosis, spongiosis, and irregular acanthosis in the epidermis. Fibrosis with vertically arranged collagen fibers and perivascular lymphohistiocytic infiltration were shown in the upper dermis. We diagnosed the case as secondary prurigo nodularis along Blaschko lines, accompanied by the preceding atopic dermatitis. We hypothesized that the patient’s underlying atopic dermatitis increased in severity along Blaschko lines, and prurigo nodularis occurred due to frequent scratching. The lesions improved with topical methylprednisolone cream, oral antihistamines and intralesional triamcinolone injection.

Objective: Bacteremia is a common cause of increased morbidity and mortality in elderly patients, but early diagnosis and identification are complex. The neutrophil-to-lymphocyte count ratio (NLR) is suggested as a useful indicator for diagnosing bloodstream infections. This study evaluated whether the NLR at admission is associated with bloodstream infections in older patients admitted to the emergency department. Methods: A retrospective, multicenter analysis was performed on patients admitted to the emergency department from November 2016 to February 2017. We included patients aged 65 years and older who visited the emergency department with medical problems. Baseline NLR values were measured upon admission to the emergency department. The primary outcome was a positive blood culture. Results: A total of 1,815 patients were included in this study. The median age was 77.25±7.38 years, and bacteremia was identified in 290 older patients (15.9%). The NLR was significantly higher in the bacteremia group (15.95±22.03) than in the non-bacteremia group (8.76±8.74, P<0.001). In the multivariate logistic regression analysis, the NLR was associated with bacteremia after adjusting for confounding factors as continuous variables (odds ratio [OR], 1.033; 95% confidence interval [CI], 1.009-1.057) and categorical variables (NLR ≥10; OR, 2.018; 95% CI, 1.246-3.268). The area under the curve of the NLR was determined to be 0.667 (95% CI, 0.639-0.694). Conclusion These results indicate that the NLR at admission to the emergency department is associated with bloodstream infections. Early suspicion of bacteremia, by determining the initial NLR value, will help treat bacteremia in elderly patients.

Systemic capillary leak syndrome (SCLS) is an unusual entity characterized by hypovolemic shock, hemoconcentration, and hypo-albuminemia associated with paraproteinemia as a result of marked capillary hyperpermeability. Complications of this syndrome can include compartment syndromes, pulmonary edema, thrombosis, and acute kidney injury. This paper reports a case of severe SCLS accompanied by acute tubular necrosis caused by hypoperfusion and myoglobinuria secondary to rhabdomyolysis, which resulted in chronic kidney disease that necessitated hemodialysis. However, there have been rare data of residual end-organ damage after acute attacks in Korea. Therefore, this paper reports a case of complicated SCLS enough to hemodialysis and that developed into chronic kidney disease.
