PURPOSE: To compare the changes in strabismus angle and deviation between two groups: a bilateral lateral rectus recession (Group 1) and a unilateral lateral rectus recession in exotropia (Group 2). METHODS: A retrospective survey was conducted on 198 patients who had received exotropia surgery in our ophthalmology clinic from September 2003 to April 2007. A total of 116 patients were in Group 1, and 82 patients were in Group 2. RESULTS: The average deviations of the first postoperative month and the first postoperative year were -1.96 D +/- 4.75, 2.5 D +/- 7.82 for Group 1 and 0.77 D +/- 2.87, 5.94 D +/- 3.38 for Group 2. Revealing statistical significance between the 2 Groups: Group 1 had 30 failure cases (25.9%) and their 1 postoperative year average deviation was 5.42 D +/- 13.97, while Group 2 showed 24 failure cases (29.3%) and their 1-postoperative-year average deviation was 13.0-79 +/- 3.04. Group 1 had less strabismus angle and a greater standard deviation than Group 2, as Group 1 had more overcorrection. Among the 30 failure cases of Group 1, 9 were overcorrected and 21 were undercorrected, but all 24 failure cases in Group 2 were undercorrected. CONCLUSIONS: The strabismus angle after lateral rectus recession showed a wider variation and a larger difference in bilateral lateral rectus recession than in the unilateral lateral rectus recession.

PURPOSE: In South Korean ferry disaster in 2014, the captain abandoned the ship with passengers including high school students still aboard. We noticed the resemblance of abandoning the ship with passengers still aboard the ferry (named the Sewol) and the ship Patna, which was full of pilgrims, in Joseph Conrad's novel "Lord Jim." The aim of this study is to see how medical students think about the role of a medical doctor as a captain of a ship by analyzing book reports on Conrad's "Lord Jim." METHODS: Participants included 49 third-year medical students. Their book reports were analyzed. RESULTS: If placed in the same situation as the character of Jim, 24 students of the 49 respondents answered that they would stay with the passengers, while 18 students indicated they would escape from the ship with the crew. Most of the students thought the role of a doctor in the medical field was like that of a 'captain.' The medical students reported that they wanted to be a doctor who is responsible for his or her patients, highly moral, warm-hearted, honest, and with high self-esteem. CONCLUSION: In conclusion, we found that "Lord Jim" induced the virtue of 'responsibility' from the medical students. Consequently, "Lord Jim" could be good teaching material for medical humanities.

Despite widespread use of antibiotics and surgical procedures for treating peritonsillar abscess (PTA), symptoms of severe inflammation such as pain and trismus during treatment result in patient dissatisfaction. The goal of this study was to perform a systematic review and meta-analysis of the efficacy of systemic steroids on the clinical course of PTA. Two reviewers independently searched the databases (MEDLINE, Scopus, and the Cochrane Database) from inception to December 2014. Studies comparing systemic administration of steroids (steroid group) with placebo (placebo group), where the outcomes of interest were pain, body temperature, hospitalization, and oral intake during the posttreatment period, were included. Baseline study characteristics, study quality data, numbers of patients in the steroid and control groups, and outcomes were extracted. Sufficient data for meta-analysis were retrieved for 3 trials with a total of 153 patients. Pain-related parameters (patient-reported scores and trismus), body temperature, and dysphagia during the first 24 hours after treatment were significantly improved in the steroid group compared with placebo group. The discharge rate during the first 5 days of the posttreatment period was significantly higher in the steroid group than the control group. However, although more patients in the steroid group returned to normal activities and dietary intake at 24 hours after treatment, the differences between the groups were not significant and disappeared after 48 hours. In the treatment of PTA, systemic administration of steroids with antibiotics could reduce pain-related symptoms, as well as provide a benefit with respect to the clinical course. However, further trials with well-designed research methodologies should be conducted to confirm our results.

Masclura tricuspidata, also called as Cudrania tricuspidata, is one of the most common Moraceae family plants in East Asia. Its trivial name follows mulberry due to the similar morphology. Investigation of the bioactive constituents of M. tricuspidata leaves yielded a new xanthone derivative along with twenty known compounds through various chromatographic techniques. A new compound was defined as mascluraxanthone (3), a prenylated xanthone glucoside on the basis of 1D and 2D NMR and MS data. Twenty known compounds were identified as four xanthone derivatives (1-2 and 4-5), two flavans (6-7), six flavanol derivatives (8-13), a flavonone (14) and seven flavonol derivatives (15-21). Among the isolated compounds, flavanol and flavonoid derivatives with 3′,4′-OH groups showed antioxidant and anti-tyrosinase activities. Conclusively, the leaves of M.tricuspidata are rich in aromatic compounds including xanthones and flavonoids. In addition, these constituents showed antioxidant and anti-tyrosinase potentials, which might be useful for oxidative stress related diseases.

OBJECTIVES: Several lines of evidence suggest the serotonergic dysfunction involved in the biological susceptibility of suicide. Tryptophan hydroxylase (TPH), the rate-limiting enzyme in the biosynthesis of serotonin, plays a vital role in serotonin metabolism. In a case-control study, we investigated whether the TPH gene was a susceptible factor for suicidal behavior in depressive patients. METHODS: The subjects were 218 depressed patients who attempted suicide and visited emergency rooms in multi-medical centers. One hundred thirty hospitalized non-suicidal depressed patients and the 161 normal controls were matched with the suicidal group. Individuals in all 3 groups were evaluated independently by a Structured Clinical Interview for the purpose of establishing a DSM-IV criteria diagnosis (SCID). The severity of depressive symptoms was evaluated using Hamilton depression rating scale (HDRS). RESULTS: There was no significant difference in genotype distributions and allele frequencies of TPH intron 7 A218C polymorphisms among 3 groups. Furthermore, no significant difference in genotype counts and allele frequencies of the polymorphisms was found among lethal suicidal depressed patients, non-suicidal depressed patients and the normal controls. CONCLUSION: This study suggests that the A218C polymorphism of the TPH gene is unlikely to have a major effect on the susceptibility of suicidal behaviors in depressive patients.

BACKGROUND AND OBJECTIVES: Although human papillomavirus (HPV) infection has been recognized as having an important role in the pathogenesis of head and neck squamous cell carcinoma (HNSCC), there is no simple and reliable screening test of HPV infection in HNSCC to date. In the present study, we investigated the usability of p16 immunohistochemical staining as a screening test for HPV infection in HNSCC. SUBJECTS AND METHOD: Paraffin blocks were obtained from 45 tonsil SCC patients, who underwent surgery as an initial treatment between 1995 and 2004. Paraffin blocks were also obtained from 20 normal controls. Expression of p16 was investigated immunohistochemically and these results were compared with results of HPV genotyping and the real-time polymerase chain reaction (PCR) assay of viral oncoprotein to validate p16 staining as a reliable diagnostic tool of HPV infection. RESULTS: The expression of p16 was found to be significantly different between tonsil SCC (32/45, 71.1%) and normal control tissues (0/20, 0%)(p<0.05). Among the 45 patients, HPV genotyping and real-time PCR assay were performed in 21 of the 32 p16 (+) patients and in 6 patients of the 13 p16 (-) patients. HPV-16 was detected in 18 (85.7%) out of the 21 p16 (+) patients and in 2 (33.3%) out of the 6 p16 (-) patients. The p16 expression and HPV-16 status was significantly correlated (p<0.05). The two patients who had HPV-16 infection but did not have p16 expression showed an episomal infection or very low viral copy number each. CONCLUSION: The p16 expression may be an useful marker of HPV infection in HNSCC and may be used as a screening test for HPV infection in HNSCC.
