The cystic hypersecretory duct carcinoma of the breast was first described in 1984 by Rosen and Scott and warrants separate discussion because of its unusual pathological features. It is morphologically distinguishable from juvenile (secretory) carcinoma and from mucinous (colloid) carcinoma or mucocele-like tumor. We present a case report of intraductal cystic hypersecretory carcinoma of the breast with hormone receptor and oncogene study. The histologic differential diagnosis, with an emphasis on benign lesions that may have a predominant cystic component, is also discussed.

IgG4-related systemic disease, including autoimmune pancreatitis, is a multi-organ disorder characterized by elevated serum immunoglobulin G4 (IgG4) concentration and IgG4-positive plasma cell infiltration. We report a case of a 66-year-old woman with IgG4-related hearing disorder, presenting with fluctuating mixed hearing loss with middle ear effusion. The serum IgG4 level was elevated and pathological examination revealed dense infiltration of IgG4-positive lymphocyte in the renal parenchyma, lung tissue and lacrimal gland. With intravenous methylprednisolone at a dose of 60 mg daily, improvement of hearing loss were observed. No recurrence was observed for 6 months with mainternance of prednisolone and methotrexate.

Diabetes is known to induce autonomic dysfunction and most experiments have been focused on the smooth muscle dysfunctions of the urinary bladder and corpus cavernosum in the genitourinary tract. The contractile response of the vas deferens is also decreased in diabetic rats and this effect may cause impairment of sperm transportation. However, few studies have been investigated the changes of contractility of the vas deferens in diabetic animals and little attention has been given to the differences between the contractilities of the prostatic and epididymal ends of the vas deferens in diabetic rats. In this study, the whole vas deferens was divided into two portions, prostatic and epididymal ends, and we examined the contractility of both segments to field stimulation at various frequencies from 4 to 64 Hz for 30 sec with pulses of 1 msec duration at 80 V in organ bath containing modified Tyrode's solution. Both initial twitch and the last contraction after 30 sec elicited by field stimulation were compared to clarify which component was more susceptible to field stimulation in control and diabetic rats. In the prostatic end, initial twitch was more impaired than the last contraction, which is believed that in diabetic rats, ATP(adenosine triphosphate) is more affected than NA(noradrenaline). In contrast, in the epididymal and the last contraction was more impaired than the initial twitch. In 64 Hz, initial twitch and the secondary contractions were not distinguished in the epididymal end of control rats, but in diabetic rats both phases were distinct. This means that the release of NA to field stimulation in the epididymal end is delayed in diabetic rats.

This study was conducted to estimate dietary choline intake of Koreans according to gender, age and region by using the data on per capita food intake in 1998 and 2001 and the data on choline contents of foods customarily eaten by Koreans. Sixty-four and 97 kinds of food items were used for the estimation of choline intake in 1998 and 2001, respectively. And these corresponded to approximately 90% of the total amount of food intake and energy intake. Based on these food items and choline content, per capita choline intake of Koreans was estimated to be 623.0 mg and 602.4 mg in 1998 and 2001 respectively : 687.2 mg and 659.1 mg in 1998 and 2001 for male : 560.2 mg and 551.0 mg in 1998 and 2001 for female. While the number of foods considered in estimation was higher in 2001 than 1998, choline intake was lower in 2001. The estimated per capita choline intake of male population was higher than that of female population by 108 - 127 mg, possibly due to the difference in total amount of food intake. The age group with the highest choline intake was different between 2 time points. Although adolescents of 13 - 19 years showed the highest intake (712.0 mg) in 1998, mid-aged adults of 30 - 49 years showed the highest choline intake (662.2 mg) followed by adolescents (645.7 mg) in 2001. In regional comparison, choline intake of the rural population (588.7 mg and 588.3 mg in 1998 and 2001 respectively) was lower than that of population in small to medium-size cities (625.1 mg and 603.9 mg) or in metropolitan cities (637.7 mg and 602.8 mg). This result revealed that per capita choline intake of the Korean population falls within the adequate range with some differences by age, sex and residing area.

To evaluate whether different qualifications of a cytologic diagnosis of "atypical squamous cells of undetermined significance(ASCUS)" predict a greater or lesser likelihood of tissue diagnosis of uterine cervix, we compared different cytologic qualifications of ASCUS with the tissue diagnosis. One hundred twenty-two con secutive Papanicolaou smears showing ASCUS in women who had undergone cervical biopsy within nearest 30 days were collected. The 122 smears were qualified as "favor reactive"(25%), "favor low grade squamous intraepithelial lesion (LSIL)"(24%), "favor squamous intraepithelial lesion(SIL)"(16%), "favor high grade squa mous intraepithelial lesion(HSIL)"(16%), and "not otherwise specified"(19%). Squamous intraepithelial or invasive lesion was pathologically confirmed by cervical biopsy in 13% of the "favor reactive", 27% in "favor LSIL", 70% in "favor SIL", 75% in "favor HSIL", and 35% in "not otherwise specified" smears. There were significant asso ciations between the favor reactive smear and the benign biopsy finding and between the favor SIL smear and the biopsy showing a squamous intraepithelial or more severe lesion. Nevertheless, most of favor LSIL smears exhibit reactive process in tissue biopsy. Conclusively, qualified ASCUS stratifies women into different risk groups for SIL. The cytopathologist should make the cytologic diagnosis of "ASCUS, favor LSIL" circumspectly.

Purpose: To report a case of recurrent optic neuritis with uveitis in a patient with myelin oligodendrocyte glycoprotein (MOG)- associated disease.Case summary: A 16-year-old female presented with left eye hyperemia, glare, and headache. The best corrected visual acuity was 1.2 in both eyes with a left relative afferent pupillary defect. Cells in the anterior chamber, optic disc edema, and subretinal fluid were present, and the distal optic nerve was enhanced on orbital magnetic resonance imaging. Although it improved with steroid treatment, it recurred 3 times in 9 months. At the second recurrence, her visual acuity was reduced to light perception, but she responded well to steroids. During the third recurrence, she visited our hospital for the first time and improved with steroid treatment. However, 18 months after treatment, optic neuritis, uveitis, and macular edema occurred, so oral steroids and eye drops were maintained. Serum anti-MOG antibody came out positive, and at the last visit, visual acuity of 1.2 in the left eye and visual function were maintained well. Conclusions MOG antibody disease (MOGAD) frequently recurs and invades various structures of the eye and various clinical manifestations have been reported. Therefore, if optic neuritis is accompanied by inflammation of the anterior chamber and retinal vessels, the possibility of MOGAD should be considered.

BACKGROUND/AIMS: Common bile duct stones are associated with the extent of dilation of the common bile duct as well as its angulation. Multidetector computed tomography (MD CT) has a good resolution for the definition of the anatomical features of the common bile duct. METHODS: The multiplanar reformation images of 398 patients that underwent multidetector CT for the diagnosis of disorders not related to the bile duct were examined. The diameter and angulation were categorized by gender and age. RESULTS: The average diameter and angulation of the common bile duct was 6.7 mm and 132.6degrees. There was a statistically significant correlation between age and the common bile duct diameter. The Pearson correlation analysis for age and diameter resulted in a value of 0.415 (p<0.001). And the common bile duct (CBD) diameter in people older than 51 years of age showed a significant difference compared to the subjects younger than 50 years of age (p<0.01). However, the degree of angulation has no correlation with age. CONCLUSIONS: We suggest that CBD diameters in patients more than 50 years of age can be more than 7 mm and be within normal limits.
