BACKGROUND/AIMS: We aimed to verify the prognostic factors of stage II rectal cancer and the effect of radiation therapy on the survival and local recurrence rate. METHODS: This study was undertaken in 202 patients who underwent curative resection of rectal cancer and confirmed to be stage II between July 1989 and December 1996. Univariate and multivariate (Cox's model) analyses of survival were employed to identify prognostic factors. Statistical significance was assigned by p value of <0.05. RESULTS: Overall recurrence occurred in 32 patients. Four patterns of recurrence were observed: hematogenous recurrence in 17 patients, local recurrence in 11, peritoneal seeding in two and simultaneous hematogenous and local recurrence in two cases. Overall 5-year survival rate was 85.6% and 5 year disease free survival rate was 82.8%. There was no significant difference in local recurrence rate and survival according to radiation therapy or location of cancer. In multivariate analysis, the number of harvested lymph node was only a prognostic factor. CONCLUSIONS: The number of harvested lymph nodes has prognostic value in stage II rectal cancer. Postoperative radiation therapy should be considered for stage II rectal cancer with poor prognostic factors although radiation did not decrease local recurrence rate in present study.

The present study was conducted to examine the morphology and antigenicity of Photobacterium damselae subsp. piscicida by culturing the bacterium in vivo in the peritoneal cavity of sea bass (Dicentrarchus labrax) within dialysis bags with either a low molecular weight (LMW) cut-off of 25 kDa or a high molecular weight (HMW) cut-off of 300 kDa. Differences were observed in the growth rate between the bacteria cultured in vivo or in vitro. Bacteria cultured in vivo were smaller and produced a capsular layer, which was more prominent in bacteria cultured in the HMW bag. Antigenicity was examined by Western blot analysis using sera from sea bass injected with live Ph. d. subsp. piscicida. The sera recognised bands at 45 and 20 kDa in bacteria cultured in vivo in the LMW bag. Bacteria cultured in vivo in the HMW bag did not express the 45 kDa band when whole cell extracts were examined, although the antigen was present in their extracellular products. In addition, these bacteria had a band at 18 kDa rather than 20 kDa. Differences in glycoprotein were also evident between bacteria cultured in vitro and in vivo. Bacteria cultured in vitro in LMW and HMW bags displayed a single 26 kDa band. Bacteria cultured in the LMW bag in vivo displayed bands at 26 and 27 kDa, while bacteria cultured in vivo in the HMW bag possessed only the 27 kDa band. These bands may represent sialic acid. The significance of the changes observed in the bacterium's structure and antigenicity when cultured in vivo is discussed.

In order to evaluate the comparison of corneal astigmatism after keratoplasty with 3 kinds of suture techniques, penetrating keratoplasty was performed in 25 patients(25 eyes) with different suture techniques, single continuous(group I, N=7), interrupted(II, N=7), and combined sutures(III, N=11) with 10-0 nylon. In group I, suture control was made from postoperative 1 month and selective suture removal was done in group II and III. The corneal astimatism was analyzed prospectively with corneal topography more than 1 year in all except 2 patients. The amout of corneal astigmatism in group I, II and III at postoperatie 1 month was 2.12D, 3.14D and 3.08D respectively (P>0.05, Kruskal-Willis test) and showed marked reduction upon postoperative 3 months. At postoperative 1 year, corneal astigmatism of each group was 2,62D, 1.49D and 2,18D respectively(P>0.05). The corneal astigmatism between keratoconus and other corneal disorders was not statistically ignificant. Interrupted suture induced least corneal astigmatism after keratoplasty compared to other suture methods even if there was no statistical significance.

Mesenteric lymphangioma was first recognized when an autopsy case was recorded in 1507 by Benevieni. It has been known clinically rare disease and probably a congenital developmental abnormality due to failure of drainage of peripheral primary lymphatic spaces. We experienced a case of abnormal rotation in intestine by mesenteric lymphangioma in a 8 years old male who showed vomiting and abdominal pain. A brief review of related literatures is also presented.

The antigenicity of Photobacterium damselae (Ph. d.)subsp. piscicida, cultured in four different growth media[tryptone soya broth (TSB), glucose-rich medium (GRM),iron-depleted TSB (TSB+IR-), and iron-depleted GRM(GRM+IR-)] was compared by enzyme-linked immuno-sorbent assay (ELISA) and Western blot analysis usingsera obtained from sea bass (Dicentrarchus labrax) raisedagainst live or heat-killed Ph. d. subsp. piscicida. Theantigenic expression of Ph. d. subsp. piscicida was found todiffer depending on the culture medium used. A significantlyhigher antibody response was obtained with iron-depletedbacteria by ELISA compared with non-iron depletedbacteria obtained from the sera of sea bass raised againstlive Ph. d. subsp. piscicida. The sera from sea bass raisedagainst live bacteria showed a band at 22kDa in bacteriacultured in TSB+IR- or GRM+IR- when bacteria thathad been freshly isolated from fish were used for thescreening, while bands at 24 and 47kDa were observedwith bacteria cultured in TSB or GRM. When bacteriawere passaged several times on tryptic soya agar prior toculturing in the four different media, only bands at 24 and47kDa were recognized, regardless of the medium used toculture the bacteria. It would appear that the molecularweight of Ph. d. subsp. piscicida antigens change in thepresence of iron restriction, and sera from sea bassinfected with live bacteria are able to detect epitopes onthe antigens after this shift in molecular weight.

Background: This study aimed to identify the initial diagnostic characteristics and treatment status of children with submucous cleft palate (SMCP) and to examine the relationship between the timing of surgical correction and the degree of articulation and resonance improvement. Methods: This retrospective study included 72 children diagnosed with SMCP between 2008 and 2016. The evaluation criteria were the age of the initial visit, total number of visits, age at the end of treatment, speech problems, resonance problems, and speech therapy. Results: Children with SMCP first visited the hospital at an average age of 34.32 months, and speech problems were identified at an average age of 48.53 months. Out of 72 children, 46 underwent surgery at an average age of 49.74 months. Four of these children required secondary surgery at an average age of 83.5 months. Among the children who underwent surgery before 3 years of age, 70% exhibited articulation improvements, with mild-to-moderate hypernasality. Articulation improvements showed no statistically significant differences according to age at the time of surgery. However, children who underwent surgery before 4 years had a better hypernasality rating than those who underwent surgery after 4 years of age. Conclusions Children with SMCP tend to undergo delayed treatment because the anatomical symptoms in some children with SMCP are unclear, and surgical interventions are considered only after speech problems are clarified. Starting interventions as early as possible reduces the likelihood of receiving secondary surgery and speech therapy, while increasing expectations for positive speech function at the end.

OBJECTIVE: The purpose of this study was to compare the efficacy and safety of escitalopram, paroxetine and venlafaxine in Korean patients with major depressive disorder (MDD). METHODS: A total of 449 Korean MDD patients were recruited in a six-week, randomized, rater-blinded, active-controlled trial and were evenly randomized to paroxetine, venlafaxine, or escitalopram treatment. RESULTS: When comparing the mean difference for the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Hamilton Depression Rating Scale (HDRS) total scores during six weeks, paroxetine (−6.4±0.4, and −5.4±0.4, respectively) was found to be significantly superior to escitalopram (−3.7±0.5 and −3.1±0.4, respectively). Venlafaxine had a significantly lower MADRS total score (−5.4±0.4) than escitalopram. When adjusting baseline variables, the response, according to the MADRS and HDRS scores, in the paroxetine group was greater than that for the escitalopram group (odds ratio [OR]=2.43, 95% confidence interval [CI]=1.42–4.16 for MADRS; and OR=2.32, 95% CI=1.35–3.97 for HDRS) and the venlafaxine group (OR=1.94, 95% CI=1.17–3.21 for MADRS; and OR=1.71, 95% CI=1.03–2.83 for HDRS). Despite that the overall tolerability was high and similar among the three groups, a total of 268 subjects (59.7%) prematurely discontinued treatment, representing the main limitation of the present study. CONCLUSION: Although a low study completion rate limits generalizability, our findings suggest that paroxetine might be superior to escitalopram in Korean MDD patients. Further studies should be conducted to draw a definite conclusion.

OBJECTIVE: It has been recognized that cold knife conization has higher incidence of postoperative hemorrhage and many techniques have been developed in an attempt to control hemorrhage. The aim of this study was to evaluate complications of Sturmdorf's suture in cold knife conization and to investigate various measures employed to reduce blood loss. METHODS: The results of 85 patients who had cold knife conization for diagnosis or treatment of cervical intraepithelial neoplasia (CIN) from August, 1997 to July, 2003 were reviewed. RESULTS: Among 85 patients, 83 patients (97.7%) had negative cut margins on conization specimen while 2 patients (2.3%) positive cut margins. 54 patients received no further treatment after cold knife conization and complications occurred in 9 patients (16.7%). Postoperative hemorrhage requiring additional hemostatic procedures occurred in 7 patients (13%), of which 6 patients were rehospitalized and 1 patient was managed at outpatient clinic with gauze packing only. Among 6 rehospitalized patients, hysterectomy was done in 2 patients and electrocoagulation in 1 patient. Packed red cell was transfused in 1 patient and 2 patients were managed with gauze packing only. Postoperative infection was found in 2 patients (3.7%). No other significant complications were noted. CONCLUSION: Cold knife conization using Sturmdorf's suture could be done to get much more accurate results of biopsy with relatively mild complication in magement of CIN, although several days? admission is needed and the other alternative methods seem to be more convenient.

Recently reports on toxocariasis are increasing by serodiagnosis in Korea. A previously healthy 17-yr-old boy complained of headache, fever, dyspnea, and anorexia. He showed symptoms and signs of eosinophilic meningitis with involvement of the lungs and liver. Specific IgG antibody to Toxocara canis larval antigen was positive in serum and cerebrospinal fluid by ELISA. He took raw ostrich liver with his parents 4 weeks before the symptom onset. His parents were seropositive for T. canis antigen but had no symptoms or signs suggesting toxocariasis. This is the first report of toxocariasis in a family due to ingestion of raw ostrich liver in Korea.
