PURPOSE: Optic nerve head surface depression in patients with glaucoma has been previously reported. We quantitatively compared the mean optic disc cup surface depth between glaucoma-like disc (GLD) patients with large cup-to-disc ratios and primary open-angle glaucoma (POAG) patients. METHODS: A total of 40 eyes of 40 patients with GLD and 40 eyes of 40 patients with POAG were included in this study. All patients had an average cup-to-disc ratio of 0.7–0.8. The optic disc area, mean cup-to-disc ratio, and mean optic disc cup volume were measured using spectral domain optical coherence tomography (Cirrus™ HD-OCT; Carl Zeiss Meditec, Inc., Dublin, CA, USA). The mean optic disc cup surface depth was calculated using the formula: (mean optic disc cup volume/[optic disc area × mean cup-to-disc ratio2]) − 200 µm. RESULTS: The mean ages of patients were 61.18 ± 11.83 and 59.65 ± 11.69 years for the GLD and POAG groups, respectively. The average cup-to-disc ratios were 0.74 ± 0.03 and 0.75 ± 0.03 for the GLD and POAG groups, respectively, but no significant difference was observed between the two groups. The mean optic disc cup surface depths were 144.74 ± 82.78 µm and 199.53 ± 90.26 µm for the GLD and POAG groups, respectively, and the difference between the two groups was statistically significant (p = 0.006, t-test). CONCLUSIONS: POAG patients showed a significantly greater mean optic disc cup surface depth compared to GLD patients with a similar mean cup-to-disc ratio. Based on the results of spectral domain optical coherence tomography, confirming the mean optic disc cup surface depth is expected to provide additional information to distinguish GLD from POAG patients.

Preventive and therapeutic effects of egg yolk antibody, immunoglobulin Y (IgY), against canine parvovirus (CPV) was evaluated in 25 pups orally challenged with CPV-2a. Oral administration of IgY using powder, paste and coated paste delivery systems was compared. Each type of IgY was administered orally for 17 days from 3 days before challenge. The group of pups administered coated IgY showed mild symptoms such as a moderate decrease in total white blood cell count, no depression, vomiting and diarrhea when compared with other groups. The overall clinical score of the group of pups administered coated IgY was significantly lower than that of the challenge control group. However, mortality did not differ among groups because not all pups received symptomatic treatment. These results implied that oral treatment of coated IgY could improve therapeutic effects against CPV challenge if pups received symptomatic treatment.

The purpose of this study was to investigate the genetic features of canine coronavirus (CCV) strains detected in Korea. M gene sequences obtained for isolates from 22 dogs with enteritis over a 5-year period were evaluated. Sequence comparison revealed that the 22 Korean CCV strains had an 87.2 to 100% nucleotide homology. Comparing to the typical reference CCV strains (type II), the nucleotide sequence of Korean strains had homology ranged from 86.3% to 98.3% (89.1% to 99.2% for the amino acid sequence) and 87.7% to 97.8% (92.4% to 100% for the amino acid sequence) when compared to FCoV-like CCV strains (type I). Three amino acid variations in the M gene were characteristic for the Korean CCV strains. Phylogenetic analysis demonstrated that the 22 Korean CCV strains belonged to four typical CCV clusters (i.e., a unique Korean CCV cluster, a type II and transmissible gastroenteritis virus cluster, an intermediate cluster between type I and II, and a type I cluster). This study was the first to identify genetic differences of the M gene from Korean CCV strains and provided a platform for molecular identification of different Korean CCV strains.

PURPOSE: IBTR! 2.0 is a web-based nomogram that predicts the 10-year ipsilateral breast tumor recurrence (IBTR) rate after breast-conserving therapy. We validated this nomogram in Korean patients. METHODS: The nomogram was tested for 520 Korean patients, who underwent breast-conserving surgery followed by radiation therapy. Predicted and observed 10-year outcomes were compared for the entire cohort and for each group, predefined by nomogram-predicted risks: group 1, <3%; group 2, 3% to 5%; group 3, 5% to 10%; group 4, >10%. RESULTS: In overall patients, the overall 10 year predicted and observed estimates of IBTR were 5.22% and 5.70% (p=0.68). In group 1, (n=124), the predicted and observed estimates were 2.25% and 1.80% (p=0.73), in group 2 (n=177), 3.95% and 3.90% (p=0.97), in group 3 (n=181), 7.14% and 8.80% (p=0.42), and in group 4 (n=38), 11.66% and 14.90% (p=0.73), respectively. CONCLUSION: In a previous validation of this nomogram based on American patients, nomogram-predicted IBTR rates were overestimated in the high-risk subgroup. However, our results based on Korean patients showed that the observed IBTR was higher than the predicted estimates in groups 3 and 4. This difference may arise from ethnic differences, as well as from the methods used to detect IBTR and the healthcare environment. IBTR! 2.0 may be considered as an acceptable nomogram in Korean patients with low- to moderate-risk of in-breast recurrence. Before widespread use of this nomogram, the IBTR! 2.0 needs a larger validation study and continuous modification.

Toxic hepatitis has been reported as a major cause of acute hepatitis, but its potential induction by herbal remedies and/or health foods is usually neglected. We experienced a case of toxic hepatitis associated with Polygoni multiflori, a Chinese herb commonly known as Ho-Shou-Wu. A 54-year-old woman consumed Ho-Shou-Wu for 1 month, after which she experienced fatigue and overall weakness. A diagnosis of toxic hepatitis was made based on her clinical history, the findings for viral markers and other laboratory data, and ultrasonography. Her condition improved considerably after she stopped taking Ho-Shou-Wu. However, she resumed taking Ho-Shou-Wu immediately after discharge from hospital, which aggravated her symptoms and liver function. She was immediately readmitted and stopped taking Ho-Shou-Wu. Her relapse into hepatitis immediate after resuming consumption of the herb is strongly indicative of the validity of Koch's postulate in this case.

BACKGROUND/AIMS: This study compared the results of cyclooxygenase-2 (COX-2) expression in inflammatory bowel disease and tuberculous colitis as evident by immunochemical staining and real time polymerase chain reaction (PCR). METHODS: Patients with ulcerative colitis (n=18), Crohn's disease (n=7), tuberculous colitis (n=7) and 10 normal controls were included. Biopsied colonic mucosa was simultaneously used for immunohistochemical staining and real time PCR. RESULTS: Patients with inflammatory bowel disease and tuberculous colitis showed high COX-2 expression by both methods compared to the normal controls. In Crohn's disease patients, the real time PCR value correlated well staining grade; this correlation was not evident in ulcerative colitis patients. In real time PCR, grossly normal colonic mucosa in ulcerative colitis also showed higher expression of COX-2 than normal mucosa. CONCLUSIONS: Real time PCR value of COX-2 is more representative of inflammation state in inflammatory bowel disease than the value from immunohistochemical staining.

Holoprosencephaly is a developmental malformation complex of forebrain and midface which arises from incomplete cleavage of the embryonic forebrain. It is subdivided into alobar, semilobar and lobar types based on the degree of growth disturbance within the anterior wall of the telencephalon, particularly in the midline. Cyclopia is the most severe form of alobar holoprosencephaly presenting a single median eye and a blind-ending proboscis usually located above the eye. We report a case of alobar holoprosencephaly with cyclopia and proboscis in premature infant.

Coronary vessel anomaly is a rare disease, with an incidence of about 0.6-1.3% of patients receiving coronary angiography. The ischemia in coronary vessel anomalies is due in most cases to atherosclerosis or compression of the coronary artery by a great vessel, but occasionally spasm of a coronary vessel anomaly is responsible for the pathogenesis of chest pain and myocardial ischemia. A 64-year-old female presented with a one-year history of effort angina. The left circumflex artery originated from the proximal right coronary artery. There was no atherosclerotic lesion in the right and left coronary arteries, but a focal spasm in the right coronary artery by ergonovine. In a patient with chest pain and coronary artery anomaly, if there is no coronary atherosclerosis, abnormal course or compression, the spasm test of the coronary artery should be documented.
