BACKGROUND AND OBJECTIVES: Raman spectroscopy is a vibrational spectroscopic technique capable of providing details on the chemical composition, molecular structure and molecular interactions in cells and tissues. Its application of distinguishing normal and cancer tissue has been studied in a variety of sites, such as the cervix, lung, larynx and skin. The purpose was to explore spectral changes between normal and cancer tissue in the larynx using Raman spectroscopy to assess the feasibility of using Raman spectroscopy for the early diagnosis of laryngeal cancer. MATERIALS AND METHOD: Laryngeal tissue specimens (13 adjacent normal and 13 cancer tissues) were obtained from patients who underwent total laryngetomy or supracricoid laryngectomy with squamous cell carcinoma of the larynx. The specimens were stored -70 degrees C until use. These specimens were defrosted at room temperature. The Raman spectra from laryngeal tissue specimens could be obtained at 300 mW and 250 scan during 15 minutes of the signal acquisition time using FT-Raman spectroscopy (Bruker Co., Karsruhe, Germany). RESULTS: Raman spectra were different significantly between cancer and adjacent normal tissues of the larynx at 1446 cm-1, 1240 cm-1, 1335 cm-1, and 1655 cm-1 (p=0.007, 0.2, 0.2, 0.3, respectively). The difference of 1446 cm-1 means the change of CH2 bending mode in protein and lipid of malignant tissue. The change of 1335 cm-1 means a decrease in CH3CH2 to a wagging mode of collagen and polynucleotide chain of malignant tissue. The difference of 1240 and 1655 means a decrease in the alpha-helix conformation of collagen. CONCLUSION: This study demonstrates the differences of Raman units between laryngeal cancer and adjacent normal tissue using Raman spectroscopy. In future, Raman spectroscopy may become a useful tool of guided biopsy for accurate pathologic diagnosis and assessment of the adequacy of resection margins.

The computed tomographic (CT) and clinical findings in 9 patients with serologically confirmed Japanese encephalitis were reviewed. In 6 patients with prominent pyramidal and extrapyramidal symptoms and signs, the main CT finding was low density areas in the thalamus, internal capsule, basal ganglia, and midbrain. Low density areas were compatible with the anatomical distribution of pathologic lesions in Japanese encephalitis. Diffuse low density in the periventricular white matter was evident in 5 of 6 cases, with ventricular compression in 2 cases, between the 1st and 7th day of illness. There was enlargement of the third and lateral ventricles and cortical sulci dilatation in 3 cases on or after the 21st day of illness. In once CT scan obtained on the 10th day of illness, diffuse low density in the periventricular white matter was observed with enlargement of lateral ventricles and cortical sulci dilatation. Gyral enhancement was noted in 3 of 4 cases within 4 days after the onset of symptoms. There was a limited correlation between the clinical and CT findings.

PURPOSE: The awareness of hereditary breast and ovarian cancer (HBOC) and BRCA testing is increasing in Korea. Compared to the sizable research on HBOC knowledge among breast cancer women, studies in the ovarian cancer population are limited. This paper aimed to investigate the level of knowledge of hereditary ovarian cancer and anxiety in women diagnosed with serous ovarian cancer in Korea and determine differences in the knowledge and anxiety according to whether genetic testing was undertaken and whether BRCA1 or BRCA2 mutations were present.METHODS: Using a descriptive research design, a cross-sectional survey was conducted on 100 women diagnosed with serous ovarian cancer at N hospital in Gyeonggi-do, Korea, from July to November 2018. The collected data were analyzed by descriptive statistics, independent t-tests, one-way analysis of variance, and Pearson's correlation coefficient using the SPSS 21.0 program.RESULTS: The hereditary ovarian cancer-related knowledge score was mid-level (mean score 8.90±3.29 out of a total of 17), as was the state anxiety level was mid-level (mean score 47.96±3.26 out of possible score range of 20–80). Genetic knowledge of hereditary ovarian cancer was associated with age, education, occupation, genetic counseling, and BRCA mutations. There were no statistically significant factors related to anxiety and there were no statistically significant correlations between knowledge level and anxiety.CONCLUSION: More comprehensive education on gene-related cancer is needed for ovarian cancer patients, especially for items with low knowledge scores. A genetic counseling protocol should be developed to allow more patients to alleviate their anxiety through genetic counseling.

Authors reviewed clinical recordings of 102 patients who were diagnosed as Guillain-Barre syndrome from 1979 to 1983 at Seoul National University Hospital. Among them, eighty-five cases were selected for the clinical study of Guillain-Barre syndrome through application of strict diagnostic criteria. And the following results were obtained. 1) There was a male preponderance (2.5:1) and an apparent predilection for the first and the second decades in this series. 2) Seasonal predilection was in summer and fall over five years. As judged from the uneven monthly incidence rate in each year, some epidemic tendency is likely to be in Guillain-Barre syndrome. 3) Sixty cases (71%) of this series had a history of antecedental events. The onset of neuritic symptoms occurred within one week from the preceding events in twenty-nine cases and one to two weeks in twenty cases. 4) The neuritic symptoms started from lower limbs in fifty cases (59%), upper limbs in eighteen (21%), cranial nerve distribution in six (7%) and developed nearly simultaneously in eleven (13%). 5) Most of the disabilities of the patients were devided into flaccid paralysis of limbs, cranial nerve dysfunction, autonomic dysfunction, respiratory difficulty and sensory abnormalities (paresthesia and myalgia). Autonomic dysfunction was observed in nine cases (11%), respiratory difficulty in thirty-one (37%), sensory abnormality in thirty-two (38%), and cranial nerve dysfunction in forty-seven (55%). 6) Authors devided the crainal nerve dysfunction into facial diplegia which was the most frequent form, bulbar palsy the next, masticatory muscle weakness the third, and ocular paresis the least. 7) There were two cases of Fisher syndrome (2.4%), three cases of polyneuritis cranialis (3.5%), and two cases of recurrence (2.4%) in this series. 8) Two cases (2.4%) died of respiratroy and bulbar dysfunction. Five cases (6%) had residual disability in motor function till six months follow-up.
