Crohn's disease is a rare inflammatory bowel disease in Korea which requires a differential diagnosis with intestinal tuberculosis. In the early stages of Crohn's diseaae, the combiation of bowel wall edema and spasm produces intermittent obstructive manifestations, so the usual subjective symptoms were appeared long standing diarrhea, low grade fever and abdominal pain and distension. We recently experienced a case of Crohn's colitis with repeated bowel obstruction in female adult who underwent surgical resection.

PURPOSE: As cardiomyopathy is more prevalent and currently the leading cause of death in Duchenne muscular dystrophy (DMD), early detection of myocardial involvement is important. The purpose of this study was to analyze myocardial strain in DMD children, for the possibility of early detection of myocardial dysfunction. MATERIALS AND METHODS: We reviewed medical records of DMD patients who were >10 years of age (15.6±1.6 years, 12.5-18 years), from March 2013 to June 2014. Data of 24 DMD children who underwent echocardiography with three-layer specific myocardial strain were compared with 24 controls (age: 9.3±4.0 years, 5.5-17 years). RESULTS: Epicardial longitudinal strain was lower in DMD (DMD: -9.3±3.8%; control: -12.3±4.3%; p=0.012). Radial strain (DMD: 24.1±11.1%; control: 37.3±25.9%; p=0.027) and strain rate (SR) (DMD: 1.68±0.91; control: 2.42±0.84; p=0.006) on parasternal short axis view were lower in DMD. Circumferential strains in the endocardium (DMD: -17.5±4.7%; control: -24.2±5.3%; p<0.001), myocardium (DMD: -12.7±3.8%; control: -18.0±4.0%; p<0.001), and epicardium (DMD: -8.4±4.0%; control: -12.2±5.0%; p=0.006) were significantly decreased in DMD. Circumferential SRs were lower in the endocardial (DMD: -1.46±0.38; control: -1.78±0.27; p=0.002) and myocardial layers (DMD: 1.02±0.27; control: -1.28±0.22; p=0.001). CONCLUSION: In DMD patients, deteriorations in myocardial circumferential strain might be an indicator for predicting cardiomyopathy.

OBJECTIVES: Pyrethroid pesticides are among the most commonly using insecticides in South Korean households and have been the subject of considerable interest among public health professionals for their potential health effects. The objective of this study is to examine the level of urinary 3-phenoxybenzoic acid (3-PBA) among elementary students in South Korea. METHODS: We conducted a cross-sectional study to evaluate pyrethroid pesticide exposure levels by measuring the urinary metabolites of 3-PBA using a gas chromatography-mass spectrometry method in March 2011. Study participants were 70 Asan-area and Incheon-area elementary students. RESULTS: All respondents had values above the detection limit, and the geometric means of 3-PBA in all children were 1.85 μg/L and 1.46 μg/g creatinine. Children with the top 10% urinary levels of 3-PBA were more likely to be girls, under nine years of age, living in a rural area, and living in a residential type apartment. CONCLUSIONS: South Korean children have a higher concentration of urinary 3-PBA compared with those of other countries. Further research identifying exposure pathways and intervention efforts to reduce environmental pesticide use are needed in South Korea.

PURPOSE: The selection of systemic therapy for breast cancer is based on the expression pattern of biological prognostic markers. Neoadjuvant chemotherapy has been considered the standard care for locally advanced breast cancer. However, its effect on the expression of biological prognostic markers is controversial. The aim of this study was to determine whether neoadjuvant chemotherapy may alter these expression patterns in patients suffering with breast cancer. METHODS: We determined the protein expression levels of estrogen receptor (ER), progesterone receptor (PR), p53 and HER-2/neu in the preoperative core needle biopsies and the final surgical specimens from 15 patients who received neoadjuvant chemotherapy between January 2002 and June 2007. As a control group, we analyzed the samples from patients who did not receive neoadjuvant chemotherapy. RESULTS: The pathologic complete tumor response rate (pCR) of the neoadjuvant chemotherapy group was 6.7% (1/15). Of those patients who did not achieve a pCR (n=14), no significant differences in the biological prognostic markers expression were observed between the two groups. Alteration of the ER or PR status occurred in 42.8% (6/14) of the patients after neoadjuvant chemotherapy and in 14.3% (2/14) of the control patients, showing there was no significant difference between the two groups (P=0.210). The hormonal receptor status was changed in 3 cases (21.4%) after neoadjuvant chemotherapy. CONCLUSION: There were no significant differences for the changes in the expression of ER, PR, p53 and HER-2/neu from the preoperative core needle biopsy to the final surgical specimens between those patients who had received neoadjuvant chemotherapy and those patients who didn't. However, changes of the ER or PR status and the hormonal receptor status occurred in 42.8% and 21.4%, respectively, of the patients who underwent neoadjuvant chemotherapy. As these changes may impact treatment, we suggest that immunohistochemical assay is necessary before and after neoadjuvant chemotherapy in patients with breast cancer.

Cervical pregnancy is a rare and dangerous form of ectopic pregnancy in which the blastocyst implants within the cervical canal below the internal os of the uterine cervix. The characteristic clinical sign is a severe asymptomatic uterine bleeding in early pregnancy or during curettage. Most cervical pregnancies result in early spontaneous abortion, complicated by severe hemorrhage from the eroded blood vessels within the cervical tissue. Because of uncontrolled profuse vaginal bleeding, total hysterectomy has been the mostly necessitated to control life-threatening bleeding. Transvaginal sonography allows early diagnosis, and conservative treatment (two-time treatment : first treatement with systemic or intraamnionic methotrexate, secondly with curettage or ligature of the uterine arteries) improves the patient's fertility. Successful treatment is defined as elimination of the cervical pregnancy with preservation of the uterus. We report two cases of cervical pregnancy managed, successfully with methotrexate, leucovorin and curettage.
