Heat shock protein of 72 kDa (HSP70) has a role in the functional modulation of sex steroid hormone receptors and in p53-associated oncogenesis and inhibits apoptosis associated with bcl-2. However, the exact role of HSP70 in the development of endometrial adenocarcinoma has not been well established. The aim of this study is to evaluate the role of HSP70 in relation with ER, PR, p53 and bcl-2 expressions and apoptosis in benign and malignant endometrial lesions. Immunohistochemical studies for HSP70, ER, PR, p53, bcl-2 and TUNEL method for apoptosis were performed in 30 cases of adenocarcinoma and 30 cases of benign endometrial lesions consisted of each 10 cases of disordered proliferative endometrium (DP), simple or complex hyperplasia (HP), and atypical hyperplasia (AH). There were no significant differences of HSP70 and bcl-2 expression rates and apoptotic index (AI) between DP, HP, AH, and adenocarcinoma. p53 expression rate in adenocarcinoma was 36.7%, but no p53 expression was identified in DP, HP and AH (p<0.05). In adenocarcinoma, HSP70 expression rate was higher in ER and PR negative adenocarcinoma (p<0.05), and p53 expression rate was higher in nonendometrioid type and FIGO grade II and III (p<0.05), but no significant difference of bcl-2 expression rate according to the histological type and FIGO grade. AI was higher in nonendometrioid type (p<0.05). There was no correlation between HSP70, p53 and bcl-2 expressions, and no significant difference of AI according to HSP70, ER, PR, p53, and bcl-2 expressions. In conclusion, higher HSP70 expression rate in poorly differentiated and ER and PR negative adenocarcinoma suggests that HSP70 inhibits ER and PR expression and may be involved in the development of poorly differentiated endometrial adenocarcinoma.

Microvascular ultrasound (US) techniques are advanced Doppler techniques that provide high sensitivity and spatial resolution for detailed visualization of low-flow vessels. Microvascular US imaging can be applied to breast lesion evaluation with or without US contrast agents. Microvascular US imaging without a contrast agent uses a sophisticated wall filtering system to selectively obtain low-flow Doppler signals from overlapped artifacts. Microvascular US imaging with secondgeneration contrast agents amplifies flow signals and makes them last longer, which facilitates hemodynamic evaluation of breast lesions. In this review article, we will introduce various microvascular US techniques, explain their clinical applications in breast cancer diagnosis and radiologic-histopathologic correlation, and provide a summary of a recent radiogenomic study using microvascular US.

Systemic lupus erythematosus is a multisystemic autoimmune disease in which the kidneys are frequently involved. Clinical diagnosis of SLE is based on the criteria of American Rheumatism Association (ARA). A few cases who were classified as SLE by the ARA criteria but were antinuclear antibody (ANA)-negative have been reported. It was reported that critical factor in ANA positivity is the choice of substrate. It is generally accepted that the cultured cell of human origin, especially HEP-2 cell, is better than tissue section or animal cells. Thus, the ANA test is negative only in approximately 2M of SLE patients when human tissue culture cells are used as substrate. We report a 25-year-old man admitted to our hospital because of generalized edema. He was found to have active lupus nephritis(WHO class IV), photosensitivity and pancytopenia. The result of FANA test which used HEP-2 cell as substrate was repeatedly negative, but anti-ds DNA and anti-Ro antibody were positive.

Microalbuminuria is a marker of generalized endothelial dysfunction resulting from arterial stiffness or insulin resistance, and brachial-ankle pulse wave velocity (baPWV) is a good measure of arterial stiffness. We aimed to investigate whether elevated baPWV is independently associated with microalbuminuria. This study included 1,648 individuals aged over 40 who participated in the baseline Multi-Rural Cohort Study conducted in Korean rural communities between 2005 and 2006. Participants were classified into less than 30 mg/g as normoalbuminuria or 30-300 mg/g as microalbuminuriausing urinary albumin creatinine ratio (UACR). The median and Q1-Q3 baPWV values were significantly higher in the microalbuminuric group both in men (1,538, 1,370-1,777 cm/s vs. 1,776, 1,552-2,027 cm/s, P < 0.001) and women (1,461, 1,271-1,687 cm/s vs. 1,645, 1,473-1,915 cm/s, P < 0.001). BaPWV was independently associated with microalbuminuria in both genders after adjusting for pulse rate; fasting blood glucose; triglyceride; homeostatic model assessment insulin resistance (HOMA(IR)) and, history of hypertension and diabetes. Fasting blood sugar and HOMA(IR) were judged as having nothing to do with multicolinearity (r = 0.532, P < 0.001). Elevated baPWV was independently associated with microalbuminuria regardless of insulin resistance among rural subjects over 40 yr.

The purpose of this study was to investigate the operational characteristics of the contract-managed highschool foodservice and to analyze the factors to effect the menu price. The data was collected from 249 highschools in Seoul. The results are as follows; Those surveyed highschools were established as 1 national, 74 public, and 174 private institution. Highschools were classified as 176 academic, 66 vocational, and 7 specific purposed institution. Students were organized as 70 boys', 23 girls', and 41 coeducational highschools. Most highschool started contract-managed highschool foodservice from 1999 and the period of foodservice contract was most 3 years and the operation styles in food distribution were 96 classrooms, 105 dining halls and 17 classrooms combined dining halls. The scale of contract foodservice management companies was 63.1% small and medium and 36.9% large enterprises. The surveyed highschools had the average meal price 2,141 won per meal and they had 1,518 pupils on the register. The participating rate to the foodservice was 68.5%. The facilities investment cost of the contract foodservice management company was 179,204,230 won for private institutions and was 138,119,010 won for national&public institutions. The period of the contract was 3.22 years in private institutions, which was significantly higher than national&public institutions which showed 2.85 years. The commissary foodservice schools had higher facilities investment cost than conventional foodservice schools. Classrooms foodservice had higher participating foodservice rate than Dining halls. The investment cost for facilities showed high in order of girls', boys', and coeducational high schools, and the number on the register and the number participating in the foodservice showed high in order of boys', girls', and coeducational high schools. The number on the register showed the highest in academic and vocational schools, specific purposed institutions in sequence, and the number participating in the foodservice showed high in order of academic schools, specific purposed institutions and vocational. However, the participating foodservice rate showed high in specific purposed institution, academic and vocational schools in order, and the meal price, the investment cost for facilities showed high in specific purposed institution, academic and vocational schools in sequence. Regionally, the district south of Han river had the average meal price 2,266.13 won, which showed higher in the eastern part which had 2,033.33 won. The western part had the average investment cost for facilities of 233,331,060 won, and the central district 126,137,140 won. The number on the register showed 1845.68 in the eastern part and 1308.00 in Dong-Jak area, that had clear differences among areas. When the period of the contract went longer, the investment cost for facilities had a tendency to increase. The significant differences were existed among meal price, the investment cost for facilities, the number on the register, the number participating in the foodservice, and the participating foodservice rate. The investment cost for facilities had increased according to the number participating in the foodservice and the participating foodservice rate. And the large enterprises showed higher participating foodservice rate than the small and medium enterprises.

A 32-year-old multiparous woman (gravida 2, para 2) with a history of previous cesarean section had acute abdominal pain and collapsed at 21 weeks of gestation. Exploratory laparotomy was performed because of the patient's worsening condition; ultrasound examination results were suggestive of massive hemoperitoneum, and fetus in vertex presentation with bradycardia. Uterine rupture between the left lower segment and borderline of the cervix in the anterior wall with active bleeding was confirmed. An uncomplicated classical cesarean section was performed, but the fetus was stillborn due to preterm birth. Hysterectomy was performed after the cesarean section. The patient was admitted to intensive care units for 3 days and was discharged in 12 days following delivery. Placenta percreta at the anterior lower segment of the uterus was confirmed in the pathology report.

PURPOSE: We examined the success rate and adverse effects of ultrasound-guided axillary and supraclavicular approach brachial plexus block. METHODS: From December 2013 to February 2014, 580 cases of patients received ultrasound-guided axillary approach or supraclavicular approach brachial plexus block. All blocks were performed by one anesthesiologist under ultrasound visualization using 0.2% or 0.75% ropivacaine 1% lidocaine with epinephrine in 1:200,000 as the anesthetic mixture. RESULTS: Failure rate of ultrasound-guided brachial plexus block was 1.2% and 0.2% in axillary and supraclavicular approach, respectively. In supraclavicular approach brachial plexus block, Honer's syndrome was observed in 17.9%, chest discomfort in 14.9%, and arterial puncture in 1%. There was no adverse effect in axillary approach brachial plexus block. CONCLUSION: Ultrasound-guided brachial plexus block serves higher success rate and lower occurrence rate of adverse effect and makes it useful for hand and upper extremity surgery. Supraclavicular approach has relatively higher success rate and lower rate of adverse effect than axillary approach.

A 45-year-old man presented with muscle pain, skin nodules and persistent hypereosinophilia over a period of 4 months. Laboratory data excluded the diagnosis of trichinosis or any other parasite infection. The patient's course of the disease over the 9 months was compatible with idiopathic hypereosinophilic syndrome. In a muscle biopsy, eosinophilic and lymphoplasma cells are predominantly infiltrated. Authors report a case of rhabdomyolysis due to eosinophilic polymyositis in idiopathic hypereosinophilic syndrome.

Mature cystic teratoma of the ovary is the most common ovarian germ cell tumor and almost benign, but malignant transformation occurs in less than 2% of benign mature teratoma. Of the malignancies arising in teratomas, squamous cell carcinoma is the most common (70-80%). The presentation in stage I disease dose not differ from that of benign cystic teratoma. In the early stage, the treatment is possible through surgical intervention alone. We experienced a case of squamous cell carcinoma of the ovary arising in mature cystic teratoma, which is presented with a brief review of literature.
