The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.

Verumontanum mucosal gland hyperplasia (VMGH) is a relatively common benign proliferative lesion which was first described by Gagucas et al in 1995. VMGH is usually found in radical prostatectomy or transurethral resection specimens and rarely in needle biopsy specimens. The histologic feature of VMGH is characterized by well-circumscribed proliferation of small glands and thus VMGH may mimic low grade adenocarcinoma. We report a case of VMGH from a 61-year-old man. The lesion coexisted with prostatic adenocarcinoma on radical prostatectomy specimen. The lesion was a well circumscribed microacinar proliferation which was present between the openings of ejaculatory ducts. The acini consisted of two cell layers with inner secretory cuboidal epithelium and outer basal cell. Typically, the lumen contained many corpora amylacea. Nuclear pleomorphism, prominent nucleolus, or mitotic figure was not identified. Because of small gland proliferation of VMGH, this lesion can be confused with other small gland proliferative lesions, such as low grade adenocarcinoma, atypical adenomatous hyperplasia, basal cell hyperplasia, mesonephric hyperplasia, and nephrogenic adenoma. To avoid misdiagnosis of VMGH as carcinoma, one should be familiar with this lesion.

Subgenus classification of Acanthamoeba remains uncertain. Twenty-three reference strains of Acanthamoeba including 18 (neo)type-strains were subjected for classification at the subgenus level by riboprinting. PCR/RFLP analysis of 18S rRNA gene (rDNA). On the dendrogram reconstructed on the basis of riboprint analyses, two type-strains (A. astronyxis and A. tubiashi) of morphological group 1 diverged early from the other strains and were quite distinct from each other. Four type-strains of morphological group 3, A. culbertsoni, A. palestinensis, A. healyi were considered taxonomically valid, but A. pustulosa was regarded as an invalid synonym of A. palestinensis. Strains of morphological group 2 were classified into 6 subgroups. Among them, A. griffini which has an intron in its 18S rDNA was the most divergent from the remaining strains. Acanthamoeba castellanii Castellani, A. quina Vil3, A. lugdunensis L3a, A. polyphaga Jones, A. triangularis SH621, and A. castellanii Ma strains belonged to a subgroup, A. castellanii complex. However, A. quina and A. lugdunensis were regarded as synonyms of A. castellanii. The Chang strain could be regarded as A. hatchetti. Acanthamoeba mauritaniensis, A. divionensis, A. paradivionensis could be considered as synonyms of A. rhysodes. Neff strain was regarded as A. polyphaga rather than as A. castellanii. It is likely that riboprinting can be applied for rapid identification of Acanthamoeba isolated from the clinical specimens and environments.

Diabetic muscle infarction (DMI) is an uncommon complication in patients with diabetes and it tends to be underdiagnosed, or misdiagnosed, clinically. Recently, we experienced a case of recurrent diabetic muscle infarction that was unusual in that the patient was younger than other patients. The patient was a 21-year-old woman with a 9-year history of maturity-onset diabetes of the young (MODY) who was referred to our department complaining of pain and edema in her right thigh. Magnetic resonance imaging (MRI) showed an increased T2-weighted signal and edema in the affected muscle. The final diagnosis was DMI. However, when the patient had partially recovered and was receiving supportive care, she had a second attack on the other side of the same leg during her hospitalization, in spite of her blood glucose level being strictly controlled. We report the clinical characteristics and imaging findings of this patient with recurrent DMI.

PURPOSE: This study was conducted in order to develop morning bread using powdered citrus peels and to examine the effect of its several biological activities for 12 weeks in overweight adults (BMI ≧ 23) living in dormitories of Chonbuk National University. METHODS: Control bread was prepared using the same formula except for replacing the wheat flour with 3% citrus peel powder. Subjects were classified according to two groups: Intake group of 3% citrus peel powder fortified morning bread (n = 30) and general morning bread (n = 30). RESULTS: The results of our study showed no significant effects of citrus peel powdered morning bread on anthropometric indices and biochemical characteristics among overweight adults. Despite the slight reduction in total-cholesterol, LDL-cholesterol, GOT, and GPT (p < 0.05), no significant differences in changes of these values were observed between the two groups. CONCLUSION: The short duration of our intervention might have resulted in the lack of any significant effect. Therefore, conduct of further studies with longer duration is warranted in order that the results from this study can be utilized as a basis for the development of food products with citrus peel powder.

BACKGROUND AND OBJECTIVES: The objective of this study was to evaluate the long-term clinical outcomes and the incidence of permanent pacemaker implantation after catheter ablation in patients with of atrial fibrillation (AF) and sinus node dysfunction (SND).METHODS: Among 3,068 total consecutive patients who underwent AF catheter ablation (AFCA), this study included 222 (9.5%; men 53.2%, 63.7±9.2 years of age, 81.5% paroxysmal AF) with underlying SND and a regular rhythm follow-up. We analyzed the rhythm outcomes, changes in the mean heart rate or heart rate variability, and permanent pacemaker implantation rate.RESULTS: During 47.5±28.8 months of follow-up, 25 (11.3%) patients received pacemaker implantations due to symptomatic SND. More than half (56.0%, 14/25) underwent a pacemaker implantation within 3 months of the AFCA, and the annual pacemaker implantation rate was 2.0% afterwards. Both the early (68.0% vs. 31.0%, p<0.001) and clinical AF recurrence (68.0% vs. 32.5%, p=0.001) rates and continuous antiarrhythmic drug use after 3 months (44.0% vs. 24.4%, p=0.036) were significantly higher in patients requiring pacemaker implantations than those that did not. An anterior linear ablation (odds ratio [OR], 9.37 [3.03–28.9]; p<0.001) and the E/Em (OR, 1.15 [1.02–1.28]; p=0.018) were independently associated with permanent pacemaker implantations after AFCA in patients with AF and SND.CONCLUSIONS: After AFCA in patients with AF and SND, 1 of 9 patients needed a pacemaker implantation and half needed implantations within 3 months. The AF recurrence rate was significantly higher in those who required pacemaker implantations after the AFCA.
