Clinical evaluation of needle-free electronic pneumatic hyaluronic acid injection treatment for facial atrophic acne scars: A prospective, randomized comparative trial.

Acne scars are common but difficult to treat, and an effective new treatment strategy is desired. This prospective, split-face randomized controlled trial was designed to compare the safety and efficacy of needle-free electronic pneumatic hyaluronic acid injection (EPI-HA) treatment for acne scars. Thirty Japanese subjects with moderate to severe facial atrophic acne scars underwent EPI-HA treatment on a randomized side of their face.

Analysis of cytokine profiles in sera of single and multiple infantile hemangioma.

Infantile hemangiomas (IH) are benign vascular tumors that are common in infancy. They vary in growth, size, location, and depth, and although most lesions are relatively small, approximately one fifth of patients have multiple lesions. Risk factors for IH include female sex, low birth weight, multiple gestation, preterm birth, progesterone therapy, and family history, but the mechanism that causes multiple lesions is unclear.

Effects of low-dose Aloe sterol supplementation on skin moisture, collagen score and objective or subjective symptoms: 12-week, double-blind, randomized controlled trial.

Daily oral intake of 40 μg Aloe sterol was shown in a double-blind clinical trial to significantly increase skin barrier function, moisture and elasticity. Ultrasonographic results also suggested that the intake of Aloe sterol increases collagen content in the dermis. Here, we evaluate the effects of a much smaller dose of Aloe sterol, approximately half that used previously, on skin functions in more detail.

Expression profiles of genes involved in poor prognosis of epithelial ovarian carcinoma: a review.

Background: Epithelial ovarian cancer (EOC) is the commonest cause of gynecological cancer-related mortality. Although the prognosis for patients with advanced cancer is poor, there is a wide range of outcomes for individual patients.

Objective: The aim of this study was to review molecular factors predictive of poor prognosis of women with EOC by reviewing microarray research identifying gene expression profiles.

Theoretical model of treatment strategies for clear cell carcinoma of the ovary: focus on perspectives.

Objectives: Among epithelial ovarian cancer (EOC), clear cell carcinomas (CCC) differ from the other histologic types with respect to their clinical characteristics, carcinogenesis and prognosis. The aim of this review is to summarize the current knowledge and future perspective on the new therapeutic targets and treatment strategies for CCC.

Materials And Methods: The present article reviews the English language literature for preclinical and clinical trials and promising molecular targets on CCC of the ovary, based on the gene expression profiling studies.

Molecular pathogenesis of endometriosis-associated clear cell carcinoma of the ovary (review).

Epithelial ovarian cancer (EOC) is the leading cause of death in women with gynecological malignancies. Among EOC, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) differ from the other histological types with respect to their clinical characteristics and carcinogenesis. Both tumor types are often associated with endometriosis.

The role of hepatocyte nuclear factor-1beta in the pathogenesis of clear cell carcinoma of the ovary.

Problem: Clear cell carcinoma (CCC) of the ovary has a number of features distinguishing it from other epithelial ovarian carcinomas (EOC) because of its characteristic histology and biology, frequent concurrence with endometriotic lesion, and highly chemoresistant nature resulting in an extremely poor prognosis. The incidence of CCC has been steadily increasing in Japan. They comprise approximately 20% of all EOC.

A neonate with umbilical arteriovenous malformation showing hemorrhagic shock from massive umbilical hemorrhage.

We describe herein the case of a 3-day-old male neonate with umbilical arteriovenous malformation showing umbilical hemorrhage. The patient was born after 38 weeks and 3 days of gestation with a birth weight of 2784 g. Sudden massive umbilical hemorrhage occurred on day 3.

The role of iron in the pathogenesis of endometriosis.

Background: Endometriosis may cause symptoms including chronic pelvic pain and infertility, and increases susceptibility to the development of ovarian cancer. Genomic studies have started to delineate the wide array of mediators involved in the development of endometriosis. Understanding the mechanisms of endometriosis development and elucidating its pathogenesis and pathophysiology are intrinsic to prevention and the search for effective therapies.

Clinicopathologic features of ovarian cancer in patients with ovarian endometrioma.

Objective: The purpose of this study was to describe the clinicopathologic features of malignant transformation in patients with ovarian endometrioma, their treatment and outcome in the Kinki region, Japan.

Patients And Methods: Patients meeting Sampson and Scott's criteria for cancer associated with endometriosis were identified by chart review and pathology reports. This retrospective survey describes 18 women with a history of ovarian endometrioma.

Iron-dependent oxidative stress as a pathogenesis for preterm birth.

Problem: Preterm birth (PTB) is an oxidative stress-related disease that lacks effective therapies partly because of the poor understanding of disease pathogenesis. The aim of this manuscript was to review molecular pathways that could be responsible for the pathogenesis of PTB. Genomic and proteomic studies have started to delineate the wide array of mediators involved in this disorder.

Two cases of pregnant women with ovarian endometrioma mimicking a malignant ovarian tumor.

The detection of an ovarian mass during pregnancy is often a diagnostic challenge. We describe 2 cases of ovarian endometrioma during pregnancy with marked mural nodules on the cyst wall. The sonographic and MR imaging findings mimicked ovarian cancer.

Molecular structure and function analysis of bikunin on down-regulation of tumor necrosis factor-alpha expression in activated neutrophils.

Objective: We performed a detailed molecular analysis of bikunin-mediated anti-inflammation (suppressive effect of cytokine release, MAP kinase activation, and nuclear translocation of NF-kB) using a truncated form of bikunin.

Materials And Methods: We obtained bikunin derivatives that contained O-glycoside-linked N-terminal glycopeptide (Bik-m1), N-glycoside-linked C-terminal tandem Kunitz domains (Bik-m2), bikunin lacking O-glycoside (Bik-c), asialo bikunin (Bik-a), bikunin lacking N-glycoside (Bik-n), and purified C-terminal Kunitz domain II (kII) of bikunin (HI-8). Enzyme-linked immunosorbent assay and Western blot were carried out to measure secreted TNF-alpha and MAP kinase activation.

Giant abdominal tumor of the ovary.

A giant abdominal tumor can exert a mass effect on surrounding structures. We report here a 34-year-old single female who presented with an increased abdominal girth and was subsequently found to have a giant abdominal mass. Large volume aspiration (85 L) at a slow rate (1 L/min) was initially performed before surgical resection to prevent the development of severe clinical hypotension after large volume aspiration.

Peritoneal disseminated recurrence and lung metastasis after surgery for stage IA uterine papillary serous carcinoma of the endometrium: a case report.

Case Report: We describe a case of synchronous peritoneal dissemination and multiple lung metastases after surgery for stage IA primary uterine papillary serous carcinoma (UPSC) of the endometrium, revealed by an uncontrollable retention of ascites.

Results And Discussion: She was initially treated with a hysterectomy, bilateral salpingo-oophorectomy and pelvic lymphadenectomy after initial presentation. Tumor recurrence, diagnosed 12 months later, has been treated with six cycles of Paclitaxel 175 mg/m(2) and Carboplatin [area under the curve 5 (Calvert Formula)] every 3 weeks and showed an advantage of this regimen.

Bikunin suppresses expression of pro-inflammatory cytokines induced by lipopolysaccharide in neutrophils.

Activated neutrophils contribute to the development of preterm delivery. Because of its ability to suppress inflammation, bikunin, a Kunitz-type protease inhibitor, is currently in clinical trials. To investigate the molecular mechanism of this inhibition, we analyzed the effect of bikunin on pro-inflammatory cytokine production and nuclear factor-kappaB (NF-kappaB) activation in mouse neutrophils stimulated by lipopolysaccharide (LPS), an inflammatory inducer.

Ovarian endometrioma--risks factors of ovarian cancer development.

Objective: Our prospective studies in Japan have found an increased ovarian cancer incidence in women with ovarian endometrioma (standardized incidence ratio, 8.95; 95% confidence intervals, 4.12-5.

Aging impairs the protective effect of magnesium supplementation on hypertension in spontaneously hypertensive rats.

Preeclampsia is a hypertensive disorder that is unique to pregnancy. Magnesium (Mg2+) supplementation is a potential new therapy to ameliorate development of hypertension. The aim of this work was to compare the effects of Mg2+ supplementation on systolic blood pressure (SBP) in young and aged rats.

Prevalence of ovarian cancer among women with a CA125 level of 35 U/ml or less.

Background: The optimal upper limit of the normal range for CA125 in ovarian cancer screening is unknown. We investigated the prevalence of ovarian cancer among women in the Shizuoka Cohort Study on Ovarian Cancer Screening (SCSOCS) trial who had an abnormal ultrasound (US) and a CA125 level of 35 U/ml or less.

Methods: Of 48,027 women enrolled in the SCSOCS trial, 40,801 women never had a CA125 level of more than 35 U/ml, and underwent transvaginal US.

Late onset of pulmonary embolism caused by lymphocyst following pelvic lymphadenectomy.

Herein is reported a case of late-onset pulmonary embolism following pelvic surgery, despite prophylactic measures in the perioperative period. Twenty-six days after hysterectomy and pelvic lymphadenectomy for endometrial carcinoma, an 83-year-old woman developed a pulmonary embolism. This was caused by pelvic lymphocyst, which, in turn, led to chronic compression of the right external iliac vein.

An acromegalic woman first diagnosed in pregnancy.

Background: Reports of pregnancy in acromegalic women are uncommon, numbering less than 100, in which a case of acromegaly first diagnosed in pregnancy is rare.

Case: A 40-year-old woman in 19-week gestation was presented with a 10-week history of photophobia and visual disturbance. Elevated growth hormone (GH) levels in the serum, an inadequate suppression of GH secretion with glucose administration and a mass image in the pituitary fossa confirmed the diagnosis of acromegaly.
