A total of 150women with singleton pregnancies who were delivered between 37 and 42weeks gestation had ultrasound scans on elective cesarean section day. The biparietal diameter(BPD), head circumference(HC), abdominal circumference(AC) and femur length(FL) were measured in all cases. Equations of estimated fetal body weight(BWT) for Korean term fetuses using AC alone, BPD/AC, AC/FL, HC/AC/FL, BPD/AC/FL, BPD/HC/AC/FL were made by stepwise multiple regression analysis and were compared with foreign equations such as Campbell(AC), Shepard(BPD/AC), Hadlock I(AC/FL), Hadlock II(HC/AC/FL), Hadlock III(BPD/AC/FL), and Hadlock IV(BPD/HC/AC/FL). The results were as follows. 1. The equations of BWT by sonographic measurement were Equation1 (AC) logeBWT=6.105936+0.005957X(AC) (R=0.876) Equation2 (BPD,AC)logeBWT=6.53614548+0.00004963X(ACXBPD) (R=0.929) Equation3 (AC,FL) logeBWT=6.25336442+0.00751602X(FL)+0.00005155X(ACXFL) (R=0.950) Equation4(HC,AC,FL) logeBWT=6.39631346+0.00004823X(ACXFL)+0.00002023X(FLXHC) (R=0.953) Equation5(BPD,AC,FL) logeBWT=5.99934074+0.00871394X(BPD)+0.00005132X(ACXFL) (R=0.960) 2. When BPD, AC and FL were measured, the addition of HC didn,t affected to accuracy of EFW 3. The best results of all equations were obtained with our equation 5(Mean error=2.36gm, Mean absolute error=96.39gm, Mean deviation + SD(%)=0.07+0.37) and among foreign equations, the best results were with Hadlock III equation(Mean error=18.35gm, Mean absolute error=107.82gm, Mean deviation + SD(%)=-0.46+0.42) 4. The equations using AC/FL (our equation 3, Hadlock I) are more accurate than those using BPD/AC (our equatione 2, Shepard) when utilizing two parameters. Therefore, equation using AC/FL is recommended when the BPD is unobtainable at term or labor 5. The percentage of cases in which the EFW was within +5% and +200gm of the actual birth weight was highest at our equation 5 for 82% and 89%, Hadlock IV equation for 79%, 88%. 6. Our equations had relatively an equal tendency to under- and overestimate fetal weight, but foreign equations, especially Campbell and Hadlock II equations tended to underestimate. 7. Analysing according to actual birth weight, our all equations gave the most accurate estimates of fetal weigh for birth weight group between 3000-3499gm, but for birth weight group above 3500gm, that was not. At birthweight group above 3500gm, the equations depend on femur length are more accurate than the equations independ on fumr length.

OBJECTIVES : The present study aimed to compare anxiety sensitivity among anxiety disorder groups, and to examine the relationships between lower-order factors of anxiety sensitivity and each anxiety disorder. METHODS : Three hundred and twenty four normal control subjects and 212 patients with anxiety disorders were enrolled in this study. All subjects completed a psychometric assessment package including the Korean Anxiety Sensitivity Index-Revised (ASI-R) test. Statistical analysis of the two groups was performed using the Mann-Whitney U test, and comparison of anxiety sensitivity amongthe anxiety-disorder groups (panic disorder-PD, general anxiety disorder-GAD, social phobia- SP, obsessive-compulsive disorder-OCD) was investigated using Kruskal-Wallis test. RESULTS : All anxiety disorder groups showed higher total scores of the ASI-R than did the normal control group (Z=-13.724, p<.001), and the mean total score of the ASI-R in the panic disorder group was the highest among the anxiety disorder groups. The mean score of each lower-order factor of the ASI-R in each anxiety disorder group was higher than that of the normal control group and there were statistically significant differences in fear of cardiovascular symptoms (PD,GAD>SP,OCD), fear of respiratory symptoms (PD>GAD, SP,OCD), and fear of publicly observable anxiety reactions (SP>PD,OCD) among the anxiety disorder groups. CONCLUSION : These results suggest that anxiety sensitivity reflects vulnerability to anxiety disorders, and that lower-order factors of the ASI-R may help in the differential diagnosis of anxiety disorders.

A 10-month-old male patient was seen with a nodular lesion on his left upper arm which developed several months after BCG vaccination. Physical examination revealed a bean sized, irregular surfaced, erythematous pustular nodule on the left upper arm at a place different from the vaccination site. Histopathologic examination of the nodule on the left upper arm showed tubercles composed of mononuclear cells, epithelioid cells and langhans type giant cells in the dermis. Caseation necrosis within the typical tubercles was noted. Prominent improvement of the lesion was observed 4 months after oral medication with isoniazid and rifampicin.

BACKGROUND AND PURPOSE: Previous studies have reported conflicting results about the prevalence of seizures in Alzheimer's disease (AD). There are few epidemiological studies on this topic in Asia. Thus, the objective of this study was to examine demographic and clinical characteristics as well as incidence for seizures in AD patients compared to non-AD patients in a prospective, longitudinal, community-based cohort with a long follow-up. METHODS: Data were collected from National Health Insurance Service-National Elderly Cohort (NHIS-elderly) Database to define patients with AD from 2004–2006 using Korean Classification Diseases codes G30 and F00. We performed a 1:5 case-control propensity score matching based on age, sex, and household income. We conducted Cox proportional hazards regression analysis to estimate the risk of epilepsy in AD patients. RESULTS: In the cohort study, patients with AD had higher risk for epilepsy than those without AD, with hazard ratio of 2.773 (95% confidence interval [CI], 2.515–3.057). This study also showed that male gender and comorbidities such as hypertension, hyperlipidemia, diabetes, and chronic kidney disease increased the risk of developing epilepsy. Patients with AD had 1.527 (95% CI, 1.375–1.695) times higher mortality rate than those in the control group. CONCLUSIONS: AD patients have significantly higher risk of developing epilepsy than non-AD patients.

Kounis syndrome is an acute coronary syndrome concurrently occurs with allergic or hypersensitivity reactions. In patient with this syndrome, inflammatory mediators released due to an allergic reaction implicate to induce coronary artery spasm and atheromatous plaque rupture. We describe a patient with coronary artery disease who developed acute perioperative myocardial infarction leading to cardiac arrest after the anaphylactic reaction to cisatracurium, which led to a suspicion of Kounis syndrome. Anesthesiologists should be aware that anaphylaxis or allergic reactions can progress to acute coronary syndrome, thereby significantly change the course of the disease.

PURPOSE: The purposes of this study were to evaluate the marginal and internal gaps, and the potential clinical applications of three different methods of dental prostheses fabrication, and to compare the prostheses prepared using the silicone replica technique (SRT) and those prepared using the three-dimensional superimposition analysis (3DSA). MATERIALS AND METHODS: Five Pekkton, lithium disilicate, and zirconia crowns were each manufactured and tested using both the SRT and the two-dimensional section of the 3DSA. The data were analyzed with the nonparametric version of a two-way analysis of variance using rank-transformed values and the Tukey's post-hoc test (α = .05). RESULTS: Significant differences were observed between the fabrication methods in the marginal gap (P < .010), deep chamfer (P < .001), axial wall (P < .001), and occlusal area (P < .001). A significant difference in the occlusal area was found between the two measurement methods (P < .030), whereas no significant differences were found in the marginal gap (P > .350), deep chamfer (P > .719), and axial wall (P > .150). As the 3DSA method is three-dimensional, it allows for the measurement of arbitrary points. CONCLUSION: All of the three fabrication methods are valid for measuring clinical objectives because they produced prostheses within the clinically acceptable range. Furthermore, a three-dimensional superimposition analysis verification method such as the silicone replica technique is also applicable in clinical settings.

Fibroelastolytic papulosis is proposed as the diagnostic term for cases previously identified as pseudoxanthoma elasticum-like papillary dermal elastolysis and white fibrous papulosis of the neck. Clinical presentation of fibroelastolytic papulosis is asymptomatic to mildly pruritic whitish-yellow papules that may coalesce into cobblestone- patterned plaques resembling pseudoxanthoma elasticum. Histology is characterized by normal, decreased, or absent elastic fibers in the papillary dermis sometimes accompanied by a thickening of collagen fibers. We report a 60-year-old woman with flesh to yellowish colored papules with cobblestone appearance, which were histologically consistent with fibroelastolytic papulosis.

Bowen's disease is an in situ squamous cell carcinoma. It usually occurs as a solitary lesion, but it sometimes occurs as multiple lesions. There are many therapeutic options for Bowen's disease. Among the therapies, some methods could be used for multiple lesions. However, the choice of treatment is important because the healing and success rates may vary according to the body site. A 60-year-old female patient presented with multiple erythematous plaques. The diagnosis of multiple Bowen's disease was based on the clinical and histologic features. There were too many suspicious lesions for one local treatment, so we treated the lesions with 5% imiquimod cream and oral acitretin. The imiquimod cream was applied every other day for 33 weeks and oral acitretin was prescribed for 13 weeks. After this treatment, most of the lesions were improved. The follow up biopsy showed only scar tissue. This case demonstrates that a combination of imiquimod cream and oral acitretin might be an alternative treatment option for multiple Bowen's disease lesions.

Pyogenic granuloma is a common angiomatous proliferation of the skin. It usually occurs in children and young adults and it develops spontaneously or traumatically. Although some cases of multiple pyogenic granulomas secondary to burn or vascular malformation have been reported in the literature, any case of spontaneous multiple pyogenic granulomas has not yet been reported in Korea. In this report, we present a case of multiple pyogenic granulomas that developed spontaneously on the scalp. A 47-year-old man presented with a 2 month history of multiple erythematous papules on his scalp. He had no other accompanying abnormality or history of trauma on the scalp. Among the papules, one lesion was evaluated. Histologically, the lesion consisted of a polypoid mass of angiomatous tissue that protruded above the surrounding tissue and intact flattened epidermis covered the entire lesion. After biopsy, the remaining lesions were treated by electrocautery. There have been no recurrences at 2 years' follow up.
