Generalized granuloma annulare is a rare skin disease presenting generalized eruption with a distinctive histologic picture. The age of onset of generalized granuloma annulare differs from that of localized granuloma annulare. Most of the patients with generalized granuloma annulare were in the fifth to seventh decades and cases of generalized granuloma annulare in infancy or in early childhood have been rarely reported. We herein report two cases of generalized granuloma annulare in 45- and 18-month-old boys, who is the youngest patient yet reported in the Korean literature. The histopathologic findings were compatible with granuloma annulare and all lesions completely involuted in two months after administration of topical or systemic corticosteroids.

Bonding of brackets is one of the essential factors for successful orthodontic treatment, so bond strength of orthodontic adhesives are very important. The purposes of this research were to compare shear bond strength of various orthodontic adhesives and to evaluate failure sites. One-hundred twenty extracted human first premolars were prepared for bonding and premolar brackets were bonded to prepared enamel surfaces with Super C Ortho, Mono- Lok2, Transbond, and Super C Ortho after applying Fluorobond. After bonding of brackets, teeth specimens were divided into 3 groups. In group 1 specimens were stored at humidor 37degrees C in 1 hour, in group 2 specimens were stored at humidor 37degrees C in 24 hours, thermocycled 10 times and in group 3 specimens were stored at humidor 37degrees C in 24 hours, thermocycled 1800 times. Then the universal testing machine Instron 6022, Instron Co., U.S.A. was used to test the shear bond strength of brackets to enamel. After debonding, brackets and enamel surfaces were examined under stereoscopic microscope to determine the failure sites. The results were as follows: 1. Shear bond strength was significantly highest of using Super C Ortho after applying Fluorobond and Super C Ortho In group 1, was highest of using Super C Ortho in group 2, and was highest of using Mono- Lok2 in group 3. 2. According to time and temperature change, in using Super C Ortho the group 2 had significantly highest strength and group 3 had lowest strength, in using Mono-Lok2 the group 2 and had higher strength than group 1 and in using Super C Ortho after applying Fluorobond shear bond strength decreased constantly. 3. The failure sites were tooth-resin interface in Super C Ortho after applying Fluorobond, Mono Lok2 and Transbond and were at almost same ratio bracket base-resin interface and tooth-resin interface in Super C Orth.

Small cell neuroendocrine carcinoma is a high-grade and poorly differentiated tumor typically presenting as primary pulmonary neoplasm. Extrapulmonary small cell carcinoma is rare. Primary small cell neuroendocrine carcinoma of the breast (SCNCB) is extremely rare, with an incidence of less than 0.1% of all breast cancers. Herein, we report imaging features of SCNCB incidentally diagnosed in a 58-year-old woman along with a literature review. The tumor was observed to be a round and circumscribed mass with rim enhancement, heterogeneous intra-tumoral enhancement, and peritumoral edema on MRI. The patient underwent breast-conserving surgery with adjuvant chemotherapy and radiation therapy. No tumor recurrence was observed during the 2-year follow-up visits after surgery.

Purpose: The study was aimed to examine components and provider’s characteristics of non-pharmacological intervention that affect delirium prevention in elderly inpatients. Additional effects on delirium prevention based on identified characteristics were explored. Methods: Studies were searched by using seven electronic databases and examined through Preferred Reporting Items Systematic Review and Meta-Analysis (PRISMA) flow diagram. The Risk of Bias (ROB) and the Risk of Bias Assessment tool for Non-randomized Study (RoBANS) were used to evaluate the quality of each included study. Results: Seven studies were selected for the systematic review. Most of the selected studies had a low risk of bias. Interventions of each study and delirium outcome were heterogeneous. Each multi-component non-pharmacological intervention consisted on average of five interventions. Giving orientation and promoting early mobilization were included in every study. Interventions that included giving orientation, promoting early mobilization, and supporting nutrition significantly decreased delirium incidence. Moreover, when health care providers who have an intimate relationship with patients provided non-pharmacological interventions, delirium incidence has significantly decreased. Conclusion Non-pharmacological intervention, such as giving orientation, promoting early mobilization, should be included to prevent delirium for elderly inpatients. It is important to include healthcare providers who have an intimate relationship or regular contact with patients in order to decrease delirium incidence.

OBJECTIVE: To analyze 543 cases of amniocentesis with indications, cytogenetic results. METHOD: This study includes 543 cases cytogenetic study results which amniocentesis to detect fetal chromosomal abnormality in the Cytogenetic Laboratory at Eun Hospital in Kwang-Ju from August 1996 to December 2000, as gestational ages, indications of amniocentesis, maternal age distributions, chromosome aberrations with cytogenetic results. The cytogenetic results of chromosome aberration was identified by parents inheritance and de novo karyotypes as parents periperal blood cytogenetic study. RESULTS: Amniocentesis performed mostly from 15 weeks to 20 weeks of gestaional ages. Requested indication of amniocentesis presents abnormal maternal serum screening (37%), infertility (23%) and maternal old age (> or =35) (17%). Chromosome aberration according to amniocentesis indication was suspected fetal anomaly by ultrasonogram (8.6%), previous family history (5.7%). Chormosome aberration following maternal ages, more 40 years old women were found highly 7.9%. The frequency of chromosome aberration was 5.5% but de novo chromosome aberration was 2.2%. Numerical aberration was overall new karyotypes (1.3%). Structural aberration was inheritance karyotypes (3.3%) and de novo karyotypes (0.9%). CONCLUSION: Amniocentesis is a effective diagnostic tools in fetal chromosome aberration. Indication of fetal chromosomal anormality by ultrasonography and advanced maternal ages is an important diagnostic method with chromosome aberrations. Prenatal fetal chromosome aberrations included inheritance and de novo karyotypes. Especially, identification of de novo chromosome aberrations may predict fetal anomaly and counsel the fetus for pregnant parents.

Purpose: High-risk pregnancy, resulting in major complications, such as abortion, gestational hypertension, and preterm labor, are on the rise, requiring intervention. Increased concentration of particulate matter that is 10 μg per cubic meter or less in diameter (PM10) due to increased air pollution and industrialization has recently been noted as a risk factor for health problems, and prior studies have reported that PM10 is related to abortion, gestational hypertension, and preterm labor. Methods: This study used data from the Korean medical panel between 2008 and 2016 to identify 879 women with normal pregnancies and 301 women diagnosed with high-risk pregnancies. The association between high-risk pregnancy and PM10 was analyzed using the annual average regional concentration during the same period by the Korea Environment Corporation. Results: At 35 years of age or older, the risk of abortion (p<0.001; 95% confidence interval [CI], 1.43–2.71) and preterm labor increased (p<0.05; 95% CI, 0.33–0.90). Married pregnant women were at a high risk of preterm labor (p<0.05; 95% CI, 0.25–0.98), and the prevalence of gestational hypertension was high in the metropolitan area (p<0.05; 95% CI, 12.09–25.93). On comparing the average annual concentration of particulate matter according to the level of atmospheric ventilation of the Korea Environment Corporation using a cutoff of ≤50 μg/m3, the probability of preterm labor was 2.2 times higher in groups exposed to particulate matter concentration of ≥50 μg/m3 (p<0.01; 95% CI, 1.49–3.25). Conclusion PM10 was related to preterm labor, and the risk of preterm labor was high if the average annual concentration of PM10 in the individual’s residential area exceeded 50 μg/m3.

PURPOSE: The purpose of this study was to investigate clinical features and culture-positive rates according to the involved lung in adolescent pulmonary tuberculosis (TB). METHODS: We retrospectively reviewed the medical records of adolescents who ranged in age from 10 to 20 years and who had been hospitalized with a diagnosis of TB at Kwangju Christian Hospital from 2000 to 2008. RESULTS: Sixty-six patients were identified with pulmonary TB: median age 16.82 years; 48.5% males. Among them, 90.9% of patients were between 15 and 20 years of age. Most patients presented with multiple symptoms, and the most common included cough (74.2%), sputum (60.6%), fever (39.5%), and night sweating (18.2%). Sputum samples were smear-positive in 28 (42.4%), culture-positive in 40 (60.6%), and PCR-positive in 46 (69.7%). The most common radiological patterns included cavitation in 18 (27.3%), pleural effusion in 18 (27.3%), lymphadenopathy in 10 (15.2%), and tuberculoma in 5 (7.6%). The prevalence of smear, culture, and PCR positive rates increased as the number of involved lobes increased (P<0.05, P<0.01, P<0.05). The median treatment duration was 7 months. Twelve patients (18.2%) had lower lung field TB (Group A) and forty-four patients (66.7%) had other areas involving TB, except for Group A (Group B), and ten patients (15.1%) had only TB pleurisy (Group C). The difference of clinical characteristics and culture rates between group A and group B was not significant. CONCLUSION: Pulmonary TB toward late adolescence is increasing. We need to pay more attention to lower lung field TB, which is difficult to detect with specific radiographic findings.

A 42-year-old man presented with severe pancytopenia and uncontrolled epistaxis. The diagnosis of SLE was made and the pancytopenia was found to be due to myelofibrosis. The pulse therapy with methylprednisolone and maintenance therapy with prednisolone reversed both pancytopenia and myelofibrosis. Although myelofibrosis has been described in SLE, this coexistence must be very rare since there has been only 19 cases showing this combination. We report a case of SLE with myelofibrosis which was reversed by the treatment with glucocorticoid.
