It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

The clincopathologic features of microcystic adnexal carcinoma are presented. Microcystic adnexal carcinoma is a recently described, very rare neoplasm characterized by a locally aggressive growth pattern, and as far as we know, only two reports on the microcystic adnexal carcinoma have been published in the Korean literature. Recently we experienced two cases of microcystic adnexal carcimoma occurred in a 32-year-old male and 27-year-old female patient. They had 2.5 x 2.0 x 2.0 cm and 1.2 x 0.9 x 0.9 cm sized, slowly growing mass in the glabella and below the lower lip, respectively. The immunohistochemical staining for CEA antigen stains the glandular structures but not pilar structures. So we thinked that this tumor would be originated from primitive adnexal cells differentiating into both pilar and eccrine structures.

Journal of the Korean Neurological Association 1998;16(4):425-431
BACKGROUND & PURPOSE: The aim of our study is to evaluate the stroke pattern, the correlation of collateralization with cerebral perfusion and stroke severity, and the utility of transcranial Doppler(TCD) to detect collateral pathways in patients with internal carotid artery(ICA) occlusion in the neck. METHODS: Thirty-six patients(28 men and 8 women, mean age of 59.6 ? 12.9 years) with ICA occlusion confirmed by transfemoral cerebral angiography(25 patients) or magnetic resonance angiography(MRA, 11 patients) were studied retrospectively. They had no potential cardiac source of stroke. We evaluated the pattern of cerebral infarcts by magnetic resonance imaging, and the number and the patency of collateral vessels, and the degree of perfusion through collaterals by cerebral angiography. The collateral vessels detected by TCD and MRA were compared with those by cerebral angiography. RESULTS: We found territorial infarcts in 23 patients(64%) and borderzone infarcts in 15(42%). Territorial infarcts(p<0.0001) and borderzone infarcts(p=0.02) occurred more in the ipsilateral hemisphere to the occluded ICA. The prevalence of small subcortical infarcts did not differ between hemispheres. Collateralizations through leptomeningeal anastomosis(p<0.01) and ophthalmic artery(OA, p<0.05) were associated with angiographically reduced cerebral perfusion. Collateralization through OA was also associated with severe symptomatic group(p<0.05); and collateralization through anterior or posterior communicating artery was associated with mild symptomatic group with marginal statistical significance(p=0.097). The number of collateral vessels was associated with neither the degree of perfusion nor the stroke severity. The sensitivity and specificity of TCD to detect collateralization through anterior communicating artery were 100% and 78%, through posterior communicating artery, 67% and 75%, and through OA, 67% and 63%, respectively. CONCLUSION: Cerebral infarcts related to a proximal ICA occlusion are more likely to be ipsilateral territorial or borderzone. The type of collateralization is more important factor for cerebral perfusion and stroke severity than the number of collateral vessels. TCD is a reliable tool for the evaluation of the collateral vessels in the patients with ICA occlusion.

BACKGROUND: Churg-Strauss syndrome (CSS) is characterized by disseminated vasculitis with multi-organ involve-ment. The purpose of this study was to determine the frequency and the types of neurologic involvement in a series of patients with CSS. METHODS: We reviewed the medical records of 16 patients (seven men and nine women, age = 41.9 (18.6) with CSS who were examined at Seoul National University Hospital. The diagnosis of CSS was based on the presence of asthma, peripheral eosinophilia (more than 10% eosinophiles), and histopathological or clinical findings of vasculitis. RESULTS: Of the 16 patients, 12 (75%) had neurologic involvement. Nine (56%) had neurologic symptoms as initial presentations of CSS. Peripheral neuropathy was detected in nine patients (56%) ; six had multiple mononeu-ropathy, and three had distal symmetric polyneuropathy. Three patients (19%) had cerebral infarctions; in two of them, a delayed diagnosis of CSS caused the recurrence of ischemic stroke. Corticosteroid therapy combined with immuno-suppressive agents usually yielded improvement or stabilization of symptoms. CONCLUSIONS: Neurologic involvement is common in CSS, usually manifesting as peripheral neuropathy. Neurologic symptoms are important initial manifesta-tions at the time of diagnosis of CSS. Furthermore, cerebral involvement is not uncommon; thus any neurologic symp-toms in patients with asthma or eosinophilia prompts an aggressive diagnostic approach to CSS.

BACKGROUND: It is well known that renal TGFbeta expression is related to the development of diabetic nephropathy. Alpha-lipoic acid (ALA), a potent antioxidant and cofactor of mitochondrial respiratory enzymes, can improve the insulin resistance and the vascular endothelial dysfunction, and suppresses the development of diabetic vascular complications. This study was undertaken to investigate whether ALA could reduce urinary protein excretion and renal TGFbeta protein expression in obese type 2 diabetes mellitus animal model, Otsuka Long-Evans Tokushima Fatty (OLETF) rat. METHODS: Obese 30 male OLETF rats were randomly divided to 3 groups at the age of 30 weeks. The rats in the Control group fed normal rat chow while the rats in the ALA group were fed with rat chow containing ALA (0.5% of food weight). Ten rats in the Pair-fed group were fed with normal rat chow, but were given the same amount of food as consumed by the ALA group. During 5 weeks of ALA feeding, food intake and body weight were checked in metabolic chamber. Blood glucose levels, HbA1c and urinary protein excretion were measured at 30 weeks and 35 weeks of age, and renal TGFbeta protein expression at 35 weeks of age was measured by Western blot and represented by relative unit (RU). Immunohistochemical staining for TGFbeta protein in renal tissue was also examined at 35 weeks of age. RESULTS: Food intake, body weight, blood glucose levels, HbA1c and urinary protein excretion among the Control, ALA and Pair-fed groups at 30 weeks of age were not different. At 35 weeks of age, food intake was significantly decreased in the ALA group than the Control group (Control group vs. ALA group, 27.7 +/- 1.1 g/day vs. 22.4 +/- 1.4 g/day, P < 0.001), and body weight was significantly decreased in the ALA group than the Control and Pair-fed groups (Control group: 694.4 +/- 10.3 g, ALA group: 600.4 +/- 7.4 g, Pair-fed group: 685.4 +/- 11.6 g, P < 0.001). Blood glucose levels were significantly decreased in the ALA group than the Control and Pair-fed groups (Control group: 157.7 +/- 4.6 mg/dL, ALA group: 130.7 +/- 4.8 mg/dL, Pair-fed group: 153.7 +/- 3.3 mg/dL, P < 0.001) although blood glucose levels from 30 weeks to 34 weeks of age and HbA1c at 35 weeks of age were not different among the groups. Urinary protein excretion and renal TGFbeta protein expression were significantly decreased in the ALA group than the Control and Pair-fed groups (urinary protein excretion, Control group: 5.033 +/- 0.254 mg/mgCr, ALA group: 3.633 +/- 0.303 mg/mgCr, Pair-fed group: 4.977 +/- 0.339 mg/mgCr, P < 0.001; renal TGFbeta protein expression, Control group: 7.09 +/- 0.17 RU, ALA group: 4.14 +/- 0.26 RU, Pair-fed group: 7.00 +/- 0.29 RU, P < 0.001). In the ALA group at 35 weeks of age, urinary protein excretion and renal TGFbeta protein expression were positively related in the Control, ALA and Pair-fed groups (Control group, r = 0.847, P = 0.002; ALA group, r = 0.954, P < 0.001; Pair-fed group, r = 0.858, P = 0.002). TGFbeta staining in glomeruli was observed in all groups but was decreased in the ALA group at 35 weeks of age. CONCLUSION: These results suggest that ALA may prevent the increase of food intake, body weight, blood glucose, urinary protein excretion and renal TGFbeta protein expression in obese type 2 diabetic rat model. The effect of ALA on diabetic nephropathy presented as proteinuria and renal TGFbeta expression in diabetic patients needs to be further clarified.

This study was conducted to investigate the effect of breastfeeding education experience on knowledge, control beliefs, and future intention toward breastfeeding to consider the needs of breastfeeding education program of university students. The breastfeeding knowledge, control beliefs and related habits of 445 male and female college students were evaluated between September 1, 2011 to April 30, 2012. Data were collected from self-administered questionnaires and analyzed using SPSS for Window V.17.0. chi2-test, t-test and ANOVA were used for the calculation of differences between groups. The percentage of students who intended to breastfeed their baby was 80.7% (male: 73.6%, female: 84.2%). Only 21.6% of students experienced breastfeeding education. Students planned to get information related to breastfeeding from their mothers (32.4%), breastfeeding experts (23.8%) and Medical doctors & nurses (10.6%). breastfeeding education group showed higher knowledge level (14.46 vs 10.56) and control beliefs (3.48 vs 3.16) to breastfeeding than non-education group (p < 0.001). General attitude toward breastfeeding was similar between groups; the specific intention to breastfeed for 6 months was higher in the education group (83.3% vs 58.2%) (p < 0.01). Percentage of students who gave correct answers to knowledge questions related to breastfeeding was also higher in the breastfeeding education group than non-education group (72.3% vs 52.8%). Among 20 questions, only 2 questions showed no significant differences between the groups. These findings suggested that breastfeeding education was effective in encouraging or improving breastfeeding practices.
