Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed by radiological studies including simple chest radiography, ultrasonography, or computed tomography. Identifying the causes of pleural effusions by pleural fluid analysis is essential for proper treatments. This review article provides information on the diagnostic approaches of pleural effusions and further suggested ways to confirm their various etiologies, by using the most recent journals for references.

Although exfoliative colonic cytology for the diagnosis of colorectal cancer has been largely abandoned due to the widespread use of colonoscopy, some authors still insiston the usefulness of colon lavage fluid. We tried evaluating the diagnostic feasibility of colon lavage fluid cytology using an orally administered balanced electrolyte solution. We collected colon lavage fluids in 106 patients prior to colonoscopy and reviewed the slides. Cytologic examination revealed neoplastic cells in 7 of 16(44%) cases of endoscopically proven adenocarcinoma patients. Therefore, we thin cytologic study of colon lavage fluid may be considered as one of the noninvasive diagnostic tools in colorectal cancer.

Successful management of mental symptoms requires proper diagnostic tools and comprehensive treatment including psychotherapy, physical therapy and psychopharmacotherapy. For this purpose. valid and reliable diagnostic instruments need to be developed. and the data regarding various treatment methods in medical and psychiatric comorbid conditions should be available. Because mental symptoms originate from various aspects of biological, psychological and social factors. each aspect may have slightly different therapeutic goal. Alterations in pharmacokinetics and pharmacodynamics of medically ill and/or old patients may complicate the treatment outcomes. Best psychopharmacological treatment needs to be elaborated in various states. Mental symptoms of the medically ill patients may be treated more effectively with an eclectic approach.

Nasopharyngeal carcinoma (NPC) is a common tumor in southern China and south-eastern Asia. Effective strategies for the prevention or screening of NPC are limited. Exploring effective biomarkers for the early diagnosis and prognosis of NPC continues to be a rigorous challenge. Evidence is accumulating that DNA methylation alterations are involved in the initiation and progression of NPC. Over the past few decades, aberrant DNA methylation in single or multiple tumor suppressor genes (TSGs) in various biologic samples have been described in NPC, which potentially represents useful biomarkers. Recently, large-scale DNA methylation analysis by genome-wide methylation platform provides a new way to identify candidate DNA methylated markers of NPC. This review summarizes the published research on the diagnostic and prognostic potential biomarkers of DNA methylation for NPC and discusses the current knowledge on DNA methylation as a biomarker for the early detection and monitoring of progression of NPC.

Neuromyelitis optica (NMO) is considered to be a rarer autoimmune disease than multiple sclerosis. It is very difficult to make a diagnosis of MNO for doctors who are not familiar with its clinical features and diagnostic criteria. We report a case of a young female patient who had been suffering motor weakness and radiating pain in both upper extremities. Cervical MRI showed tumorous lesion in spinal cord and performed surgery to remove lesion. We could not find a tumor mass in operation field and final diagnosis was NMO. NMO must be included in the differential diagnosis of lesions to rescue the patient from invasive surgical interventions. More specific diagnostic tools may be necessary for early diagnosis and proper treatment.

22 Cases of traumatic diaphragmatic injuries treated at the Department of Thoracic and Cardiovascular Surgery in Chon-Buk National University Hospital from Jan. 1979 to Oct. 1988 were reviewed in this study. Of the 22 cases, 18 were male and 3 were female, a ratio of 4.5:1. This ratio revealed high incidence in male patient. The age distribution ranged from 2 to 60 years and mean age was 31 years. The modes of injury were as follows: 11 stab wound, 5 traffic accident, 2 fall down, 2 fighting injury, 1 compression wound by sand bag, and 1 slip down injury. Useful diagnostic tools were chest X-ray with or without radiopaque dye swallowing, which was the most commonly diagnostic, UGI series, and thoracoscope. Operations were performed in 22 cases, and 18 cases were through thoracotomy. The herniated organs through the ruptured diaphragm were stomach, omentum, liver, spleen, colon, and small bowel. There were associated injuries, and the most commonly associated was rib fracture. There was no postoperative death.

Tuberculosis is a disease with high morbidity and mortality in children worldwide. Despite significant improvements in diagnostic methods, scientific researches and clinical trials for new regimens of treatment or prevention in adult tuberculosis, childhood tuberculosis has been relatively neglected. Children are at high risk of severe disease, and reactivation of latent infection in adulthood perpetuates the epidemic. Therefore, a policy of tuberculosis control in childhood should be emphasized to improve control in the total population. To understand the new view of childhood tuberculosis, this article describes changes in the disease's national epidemiology, new diagnostic tools and treatment strategies, and multi-drug resistance.

This report presents a case of cervical pneumatocysts as an incidental finding on cone-beam computed tomography. Pneumatocysts are gas-containing lesions of unknown etiology. They usually present in the ilium or sacrum, adjacent to the sacroiliac joint. In the literature, 21 case reports have described cervical pneumatocysts. Cervical pneumatocysts should be differentiated from other lesions, such as osteomyelitis, osteonecrosis, and neoplasms, as well as post-traumatic and post-surgical cases. Computed tomography, cone-beam computed tomography, and magnetic resonance imaging are appropriate tools to diagnose cervical pneumatocysts.

Two influence diagnostic methods for the common mean model are proposed. First, an investigation of the influence of observations according to minor perturbations of the common mean model is made by adapting the local influence method which is based on the likelihood displacement. It is well known that the maximum likelihood estimates are in general sensitive to influential observations. Case-deletions can be a candidate for detecting influential observations. However, the maximum likelihood estimators are iteratively computed and therefore case-deletions involve an enormous amount of computations. An approximation by Newton's method to the maximum likelihood estimator obtained after a single observation was deleted can reduce much of computational burden, which will be treated in this work. A numerical example is given for illustration and it shows that the proposed diagnostic methods can be useful tools.
