The high incidence antigert Jr" was first identified in 1970 by Stroup and Macllroy. Anti-Jr~ was immune antibodies developed by transfusion or pregnancy and occasionally cause hemolytic disease of the newborn and transfusion reaction, but these usually mild. We are reporting the first case of anti-Jra in Korea, which was identified in pregnant woman with transfusion history. The 35 year old pregnant woman(G6P4L1D3A1) admitted to treat for incompetent internal os of cervix on department of Obstetrics and Gynecology. Prenatal irregular antibody screening was negative. One unit of RBC was transfused at 21 gestational weeks for correction of anemia. One week later, irregular antibody was detected in her serum. The antibody reacted best by indirect antiglobulin test and panagglutinated all identified cells. The titer was 1 : 8. The antibody was identified as anti-Jr by Dr. Osaka Red Cross Center. Her phenotype of Jra was Jr(a-), but there was no Jr(a-) person in her family. She might have anti-Jra in her serum with undetectable level due to multiple pregnancies. In this case, the development of anti-Jr was stimulated by one unit of RBC transfusion with anamnestic reaction. The titer of anti-Jr was gradually reduced during pregnant period. She delivered at 37 gestational weeks by cesarian section. The baby was clinically well at birth and typed as Jr(a+).

We experienced a female neonate with congenital nephrotic syndrome (CNS) associated with congenital diaphragmatic hernia (CDH). Because of the rare combination of two conditions, we report this case with literature review. CDH was found immediately after birth and emergency operation was done for hernia repair. But on the next day, generalized edema and oliguria(0.59 mL/kg/hour) was found and her blood chemistry showed hypoalbuminemia (1.6 g/dL), increased BUN (27.7 mg/dL) and serum creatinine( 1.8 mg/dL) along with heavy proteinuria (4+). We started albumin infusion with a bolus of intravenous furosemide. We suspected the neonate had congenital nephrotic syndrome and her 24hr urine protein was 1,816 mg/day. In spite of immunosuppressive therapy, the nephrotic syndrome and renal failure progressed. We started peritoneal dialysis on the day of life 22 but it was not satisfactory. She was complicated by intracranial hemorrhage and multi-organ failure and expired at 34 days of age. Kidney necropsy was performed which showed diffuse mesangial sclerosis (DMS). Her chromosome study revealed 46, XX and her gene study revealed a heterozygous missense mutation, Arg366His, in Wilms tumor suppressor gene (WT1). This case deserves attention on account of the 4th case of CNS with CDH revealing the Arg366His mutation in the WT1 gene andG the 1st case of early onset renal failure without male pseudohermaphroditism and Wilms tumor with CNS, CDH and the Arg366His mutation in the WT1 gene. So, this report gives support to the hypothesis that Arg366His mutation in the WT1 gene can result in CNS and CDH.

PURPOSE: To evaluate the mammographic and clinical features of bilateral breast cancer. MATERIALS AND METHODS: We retrospectively reviewed clinical records (n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. RESULTS: Of the 23 cases of bilateral breast cancer, 8 (34.8%) were synchronous and 15 (65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59 (mean 43) years; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of themetachronous pairs was 9.1 years. In 11 of 23 cases (48%), tumors were located in the same quadrant, and in the other 12 cases (52%), they were in different quadrant. At mammography, five of 15 metachronous cancers (33%) were similar in appearance and 10 pairs (67%) were different. In 4 of 23 cases (17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23 (57%), cancer in the second breast was at this same stage. CONCLUSION: In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

Backgound: The aim of this study was to compare the levels of perception of and compliance with handwashing between the groups of direct patient contact and indirect contact in a tertiary-care university hospital. METHODS: A cross-sectional study was conducted in a university hospital with 4,500 employees. A questionnaire, containing questions on demographic data and the perception of and compliance with handwashing, was distributed to and collected from a total of 1,087 employees from June 25 to July 10, 2005. RESULTS: The study subjects washed their hands an average of 11.2 times (range, 1-100) per day: nurses washed their hands more frequently than others. The average duration of handwashing by employees was 18.8 seconds. Those in the direct patient contact group scored significantly higher points than did those in the indirect contact group in both perception (P<.021) of and compliance (P<.001) with handwashing. CONCLUSION: Education for handwashing is needed direction employees who have indirect contact with patients to improve their compliance with handwashing.

This study was performed to assess the radiopacity of a variety of canal filling and retrograde root-end filling materials according to the specification concerning root canal obturation materials. Ten materials including Gutta-percha pellets, amalgam, Fuji II LC, Dyract(R) AP, Super EBA(R), IRM(R), AH 26(R), Sealapex(TM), Tubli-Seal(TM) and dentin were evaluated in this study. In the first part, densitometric reading of an each step of aluminum step wedge on occlusal film were performed at 60 kVp (0.2, 0.3, 0.4 s), 70 kVp (0.2, 0.3, 0.33 s) to decide appropriate voltage and exposure time. In the second part, ten specimens which are 5 mm in diameter and 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm in thickness, were fabricated from each material studied. The specimens were radiographed simultaneously with an aluminum step wedge under decided condition (60 kVp, 0.2 s). The mean radiographic density values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained. 1. Among the various conditions including 0.2 s, 0.3 s, 0.4 s at 60 kVp and 0.2 s, 0.3 s, 0.33 s at 70 kVp, the appropriate voltage and exposure time that meet the requirement of density from 0.5 to 2.0 was 0.2 s at 60 kVp. 2. All of the materials in this study had greater radiopacity than the minimun level recommended by ISO No. 4049 standards. 3. Most of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards except for Fuji II LC and Dyract. It suggests that all experimental canal filling and retrograde root-end filling materials have a sufficient radiopacity that meet the requirement concerning root canal obturation materials except for Fuji II LC and Dyract.

PURPOSE: To evaluate the usefulness of routine mammography in the detection of local recurrence of breast cancer after mastectomy. MATERIALS AND METHODS: The clinical and mammographic records of 45 patients whounderwent modified mastectomy due to breast cancer were prospectively reviewed. The methods of mastectomy wereAuchincloss (n=36), Patey (n=8) and simple resection (n=1). RESULTS:s Among the 45 patients, five palpable lesionswere detected on physical examination: two of the five were confirmed as tumor recurrence; on mammography, anodule with microcalcifications and low-density lesion was seen, but the other three were benign. In 40 patientsthe results of palpation were negative and during follow-up (mean, 10.9 months ) no newly developed lesions wereseen. On mammography, ten of 45(22.2%) patients showed abnormalities, namely local skin thickening(n=4,40%),increased density in subcutaneous tissue(n=2,20%), nodules(n=2,20%), benign calcification(n=1,10%) and focallow-density lesion(n=1,10%), but only one case with a nodule was confirmed to be recurrence. CONCLUSION: Routinemammography of a mastectomy site was not useful for the differentiation of palpable lesions.

Nasal dermoid cysts are rare neoplasms, which are diagnosed frequently in childhood. These lesions are derived from both ectoderm and mesoderm, and have keratinizing epithelium with skin appendages. A fistula, pit, or mass is the common clinical presentation. The diagnosis is primarily based on the medical history, physical examination, clinical symptoms, and radiologic findings. Complete surgical excision is the treatment of choice. A 15-year-old boy presented with a fistula on the nasal vestibule, which existed from birth. Fistulography revealed a contrast-filling fistulous tract and cyst in the caudal portion of the nasal septum. The lesion was removed surgically and pathology confirmed the diagnosis of dermoid cyst. We report, with a review of the literature, a rare case of dermoid cyst that occurred from the nasal septum.

PURPOSE: To compare the efficacy of inflammatory markers, the Laboratory-score, and a new laboratory combined model for predicting serious bacterial infection (SBI) in young febrile children.METHODS: The presence of SBI was reviewed in previously healthy children aged 3 years or younger with fever (> 38℃) who visited the emergency department from 2017 through 2018. Areas under the curves (AUCs) of the receiver operating characteristic curve for SBI were compared with individual inflammatory markers (white blood cells [WBC] count, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], procalcitonin [PCT], and urine WBC count), the Laboratory-score, and a laboratory combined model. The latter model was developed using logistic regression analysis including ESR, CRP, and PCT.RESULTS: Of the 203 enrolled children, SBI was diagnosed in 58 (28.6%). For SBI prediction, the Laboratory-score showed 51.7% sensitivity (95% confidence interval [CI], 38.2%–65.0%) and 83.5% specificity (95% CI, 76.4%–89.1%). The AUC of the Laboratory-score (0.76) was significantly superior to the values of all individual inflammatory markers (WBC, 0.59 [P = 0.032]; ESR, 0.69; and CRP, 0.74 [P < 0.001]) except that of PCT (0.77, [P < 0.001]). The AUC of the laboratory combined model (0.80) was superior to that of the Laboratory-score (0.76) (P < 0.001).CONCLUSION: In this study, the new laboratory combined model showed good predictability for SBI. This finding suggests the usefulness of combining ESR, CRP, and PCT in predicting SBI.
