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.

Trichosporon pullulans has recently been recognized as a human pathogen. Given its rarity, however, few reports describe infection attributable to this fungal pathogen. In immunocompromised hosts, T. pullulans infection is associated with significant mortality. For the first time in Korea, we report a case of T. pullulans infection in a non.neutropenic patient. A 70.year.old woman was diagnosed with metastatic colon cancer. She did not undergo chemotherapy and received only supportive care and intravenous nutrition via the subclavian vein. Sixteen days after admission, a fever developed. Three sets of blood culture and a catheter tip culture were carried out and T. pullulans grew in all cultures. Although she was treated with amphotericin B deoxycholate and catheter removal, she died on hospital day 40 due to persistent fungemia.

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.

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.
