The rapid frozen section method is a means of intraoperative pathological diagnosis, first introduced by Welch in 1891 and developed as a diagnostic tool by Cullen, Wilson, MacCarty et al. This method serves useful purposes, such as determining the malignancy or benignancy of a suspected lesion, determining the adequacy of a biopsy of a suspected lesion, confirming the presence or absence of metatasis, and identifying small structures. But it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations and the accuracy of the frozen section method and the materials studied was total cases of frozen section during recent 5 years. The ovarall accuracy of the frozen section diagnosis of 1,603 cases was 96.2% with 0.3% of false positive, 3.5% of false negative and 2.8% of incorrect histological diagnoses or grading errors the tissues submitted for frozen section were lymph node, breast, gastrointestinal tract and soft tissue in decreasing order of frequency. The false positive cases were four in number, while the false negative cases were 53, one third of which were the misdiagnoses of the presence of ganglion cells in Hirschsprung's disease.

We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

Myxoma is a rare nonepithelial neoplasm of the larynx frequently misdiagnosed as a large vocal polyp due to its slow-growing nature. Myxoma is a benign but often infiltrating neoplasm of uncertain mesenchymal cell origin, characterized by irregular round, spindle or stellate cells within a matrix containing abundant mucoid material, scant vascularity and a variable meshwork of reticulum and collagen. We report one case of myxoma with life-threatening dyspnea requiring tracheotomy.

Malignancy may cause variable musculoskeletal symptoms which resemble connective tissue disorder. This symptoms as a fine sign of hidden neoplasm can precede the diagnosis of underlying malignancy. But only one case of stomach cancer associated with cancer arthritis was reported in the world. This fact is very interesting in Asia which has high prevalence of stomach cancer. We experienced one case of gastric adenocarcinoma with oligoarthritis involving both knee and right elbow. A 48-year-old man was diagnosed stomach cancer by gastric endoscope and biopsy. After then, he complained pain, tenderness, heating sensation, swelling of both knee and right elbow with high fever. Both knee MRI showed abundant synovial effusion and soft tissue edema. Full dose of nonsteroidal anti-inflammatory drug was not effective to control fever and arthritis. But fever and arthritis were gone after resection of tumor.

With the increasing use of PD as a replacement therapy in chronic renal failure, the number of complications related to PD also has increased. One of these is hydrothorax associated with pleuroperitoneal communications. Diagnosis is based upon confirming that the fluid in pleural space is dialysate. The chemical characteristics of the pleural fluid can help diagnose dialysate in pleural space. One can use dialysate mixed with dye (methylene blue, indigo). Peritoneographies with contrast and radionucleotides are safe, accurate, and reliable methods of diagnosing peritoneal defects. While these substances do not damage the peritoneum, their diffusion is low. We report 2 cases of hydrothorax associated with pleuroperitoneal communications in CAPD patients. We employed CT peritoneography and peritoneoscintigraphy to diagnose the hydrothorax associated with pleuroperitoneal leak.

A case of multiple myeloma with massive pleural effusion is reported. A 53 year-old previous known multiple myeloma patient vistited our hospital complaining of cough with sputum. Radiologic study revealed multiple osteolytic bony lesions and left side pleural effusion. The effusion were bloody exudates containing numerous atypical plasma cells. The tumor cells showed pleomorphism, eccentric nuclei, prominent nucleoli, perinuclear halo, multincleation, and chromatin patterns of occasional cart-wheel appearance. The cytological examination of pleural fluid established the malignant nature of the effusion with multiple myeloma.

OBJECTIVES: The Korea Health Promotion Foundation has performed the None-Smoking Project using the Quit-Smoking Clinics in all health care centers. The success rate of quitting smoking in the Quit-Smoking Clinics have run over 40% in the self-reports. The aim of this study was to assess the success rate of quitting smoking using the nicotine and cotinine concentrations in saliva and to find out the factors that influence the success of quitting smoking. METHODS: The author collected the data of 122 participants from the Quit-Smoking Clinic in the city of Daejeon and the data 13 nonsmokers as control after their written consent in 2009-2010. Following the initial visit, the unstimulated saliva samples were collcted at the visits after 2 weeks, 2 months, 4 months and 6. The concentrations of nicotine, cotinine, and OH-cotinine were analyzed using the High Performance Liquid Chromatography. The cutoff for the cotinine concentration that distinguished the smokers from nonsmokers was set at 10 ng/ml. RESULTS: The baseline participants who visited the clinic were 84 paritcipants after 2 weeks, 65 after 2 months, 40 after 4 months, and 22 after 6 months. The median concentrations of cotinine (P=0.017) and OH-cotinine (P<0.001) decreased over time. The success rates of quitting smoking were calculated at 32.1% after 2 weeks, 41.5% after 2 months, 42.5% after 4 months, and 50.0% after 6 months, in the participants who returned to the clinic. The Cotinine level after 2 weeks correlated high-positively to the concentration of that over time (r>0.7). The amount of smoking in a day, the period of smoking, and the total amount of smoking did not correlate to the success of quitting smoking as measured in the cotinine level. CONCLUSIONS: In spite of the limitation of the high drop out rate in the participants, it was suggested that the active intervention at 2 weeks could make the success rate of quitting smoking higher, as the cotinine level at 2 weeks correlated to the concentrations after that point very positively.
