Immunochemical analysis of iron transporters and M2 macrophages in ovarian endometrioma and clear cell adenocarcinoma.

The association between iron ions and endometriosis-associated ovarian cancer (EAOC) has been previously investigated to elucidate EAOC carcinogenesis; however, the dynamics of iron deposition in the endometrial epithelium and endometrial stroma of ovarian endometrioma (OE) remains unknown. The present study aimed to determine the expression of iron transporters on the cell surface and the distribution of tumor-associated macrophages (TAMs) englobed with iron in the endometrial stroma. The current retrospective study investigated 20 OE and 18 ovarian clear cell adenocarcinoma (CCC) samples, using Perls Prussian blue staining and immunohistochemistry of iron transporters, including divalent metal transporter 1 (DMT1), transferrin receptor (TfR) and ferroportin (FPN). Additionally, samples were stained for CD68, CD11c, CD163 and CD206, and double-immunostained for iron and CD163 to define the distribution of macrophages. Iron transporters were identified on the endometrial epithelium of OE and CCC tumor cells, and TAMs were englobed with iron in the endometrial stroma of OE and CCC. Histological findings revealed DMT1 upregulation in OE and CCC, whereas lower TfR and FPN expression was observed in OE than in CCC. M2 macrophages were englobed with iron ions in the deep layers of the OE and CCC stroma. The endometrial epithelium located in the endometrial stroma of one patient with OE and the endometrial epithelium adjacent to CCC in two patients with CCC stained positive for the tumor proliferation marker Ki67. Epithelium infiltrating the stroma of OE may become the origin of cancer under the influence of M2 macrophages englobed with iron. These findings provide new perspectives on the malignant transformation of OE into EAOC and its possibility as a precancerous index.

[The consciousness survey and the effect of educational intervention of Advance Care Planning (ACP) including post-mortem to elderly residents living in old New Town of big city].

AIM: Awareness reform aims to enable survival in an aging society, and ultimately, improve healthcare. An ideal way to achieve this is by implementing Advance directive (Ad) and Advance Care Planning (ACP), which do not usually include postmortem events. This study aims to create opportunities for Ad and ACP to include the postmortem period as a trigger for this awareness reform. METHODS: We conducted an Ad/ACP enlightenment lecture, and a questionnaire survey pre- and post-lecture for the elderly in old New Town, which is known for its aging society. The questionnaire comprised 38 multiple-choice questions covering 6 themes assuming an advanced state of dementia. RESULTS: There were 35 participants (7 men and 22 women) aged 40-89 years. Several people left during the lecture, making it difficult to capture the precise transformation effect with regard to changing of mind. However, the effect of enlightenment was identified as a result of the consciousness survey. A statistically significant change in consciousness occurred in response to social contribution after death. Furthermore, notably more people wanted emergency transportation compared to those wanting resuscitation and extension of life. CONCLUSIONS: The medical treatment desired might vary over time. Even the desire for life extension may differ significantly among individuals. This survey indicated a divergent view between the general public and medical staff, regarding a series of medical actions. We must persistently promote opportunities for enlightenment in cooperation with the general public (i.e., the communities and families we serve).

Managing vulvovaginal hematoma by arterial embolization as first-line hemostatic therapy.

OBJECTIVE: A puerperal vulvovaginal hematoma may continue to grow after a surgical procedure and may require blood transfusion. Thus, we selected arterial embolization for hemostasis as the first-line management in two cases of large vulvovaginal hematoma. MATERIALS AND METHODS: Case 1 was a 32-year-old pregnant woman. After delivery, a 10-cm vulvar hematoma developed. An enhanced computed tomography (CT) scan revealed active bleeding. Arterial embolization was performed and complete hemostasis was obtained. Case 2 was a 34-year-old woman with a recurring hematoma after delivery. An enhanced CT scan revealed extravasation in the hematoma. Gelatin sponges were applied and complete hemostasis was obtained. In both cases, arterial embolization was successful without requiring blood transfusions. RESULTS AND CONCLUSION: We successfully managed two cases of puerperal vulvovaginal hematoma by arterial embolization based on the evaluation of an enhanced CT scan. In conclusion, we suggest arterial embolization to be a viable option for first-line treatment in the management of vulvovaginal hematomas.

Increase in the cervical length after the loop electrosurgical excision procedure for grade III cervical intraepithelial neoplasia.

This study aimed to determine whether the cervical length increases over a period of six months, after the loop electrosurgical excision procedure (LEEP) for grade III cervical intraepithelial neoplasia (CIN), and to identify the factors associated with an increase in the cervical length. We retrospectively reviewed the medical records of 183 patients who underwent the LEEP between April 2011 and March 2014, at the Department of Gynaecology, Kyosai Hospital. Transvaginal ultrasonography was performed at two, three and six months after the LEEP, and the mean increase in the cervical length between two and three months, two and six months, and three and six months were 2.07, 5.23 and 2.92 mm, respectively. The increase in the cervical length was not associated with age, gravidity, parity and the width of CIN. In conclusion, the cervical length may increase gradually over a period of six months after the LEEP.

Delayed diagnosis of single compartment muscle contusion after radical hysterectomy in the lithotomy position: A case report.

INTRODUCTION: Muscle contusions usually occur as a result of blunt trauma, which damages the muscle fibers and connective tissue without breaking the skin. Rapid bleeding can cause an increase in pressure that requires surgical intervention, commonly referred to as compartment syndrome. Here, we report a case with delayed diagnosis of single compartment muscle contusion in which compartment syndrome did not develop. PRESENTATION OF CASE: A 50-year-old woman underwent radical hysterectomy. She complained of edema and tenderness in the lower left leg on postoperative day 6. The serum creatine phosphokinase level was slightly elevated at 177 IU/L (normal range: 6-142 IU/L). T2-weighted magnetic resonance imaging revealed swelling of the muscle in the deep posterior compartment of the lower left leg, edematous fascia, and subcutaneous adipose tissue. She recovered naturally without other complications. DISCUSSION: In the lithotomy position during surgery, muscle contusion might occur, without general symptoms. CONCLUSION: Magnetic resonance imaging is useful for diagnosis. For patients who complain of edema and tenderness in the lower leg after surgery in the lithotomy position, muscle contusions should be considered.

Expectant management of a case of uterine arteriovenous malformation with an ovarian artery aneurysm.

Uterine arteriovenous malformations are rare and their true prevalence is unknown. Selective arterial embolization is used as first-line therapy for acute severe vaginal hemorrhage associated with uterine arteriovenous malformations. However, some patients with no vaginal bleeding have been treated conservatively, so the optimal treatment modality for arteriovenous malformations is unclear. We describe a 58-year-old woman with uterine arteriovenous malformation and an ovarian artery aneurysm who was successfully treated with an expectant management approach along with an assessment of age, symptoms, and imaging findings.

Microbiota analysis of Caspian Sea yogurt, a ropy fermented milk circulated in Japan.

We analyzed the microbiota of domestic ropy fermented milk, Caspian Sea yogurt (or 'kasupikai yohguruto' in Japanese), circulated in Japan. We collected six varieties from five localities. Lactococcus (L) lactis ssp. cremoris was isolated from all samples as the dominant strain at levels of 10(8)-10(9) CFU/g. We show this strain produces an extracellular polysaccharide (EPS) that causes the unique characteristic viscosity of the product. From analysis of the RAPD pattern of 60 bacterial isolates from the six samples, we found that 59 strains from a total of 60 isolates were identical and produced this viscosity. Furthermore, PFGE analysis of representative strains from each sample indicated that the isolates could be classified into four subgroups. This suggests these L. lactis ssp. cremoris strains found in Caspian Sea yogurt may have been slightly mutated during subculture in Japan. In addition, Lactobacillus (L.) sakei ssp. sakei were isolated from three samples; L. plantarum, Gluconoacetobacter sacchari and Acetobacter aceti were isolated from two samples; and L. paracasei, L. kefiri, Leuconostoc (Leu.) mesenteroides were isolated from one sample.

The long-term efficacy of Helicobacter pylori eradication therapy in patients with idiopathic thrombocytopenic purpura.

BACKGROUND AND AIM: A beneficial effect of Helicobacter pylori (H. pylori) eradication in patients with H. pylori-positive idiopathic thrombocytopenic purpura (ITP) has been reported by several investigators; however, it was not clear whether the recovered platelet count after H. pylori eradication was maintained for a long period. METHOD: Thirty-eight ITP patients who were examined for H. pylori infection were assessed. H. pylori-positive patients received a standard antibiotic therapy for H. pylori eradication. We investigated the long-term effect of H. pylori eradication on platelet recovery in patients with H. pylori-positive ITP. RESULTS: Of the 38 ITP patients, 26 (68.4%) were positive for H. pylori. The response rate of platelet recovery was 56.5% (13/23 patients). Twelve patients showed complete response (CR) and one showed partial response (PR). The mean platelet counts 6 months after eradication significantly increased from 31 x 10(9)/L to 129 x 10(9)/L in 23 H. pylori-eradicated patients (P < 0.001). The median platelet counts of responders 1, 2, 3, and 4 years after eradication were 168 x 10(9)/L (n = 10), 193 x 10(9)/L (n = 9), 168 x 10(9)/L (n = 7), and 243 x 10(9)/L (n = 4) after a mean follow-up of 25.8 months. CONCLUSION: Eradication therapy for H. pylori-positive patients with ITP was effective and a favorable effect was maintained for long periods.

Oral administration of freeze-dried kefir reduces intestinal permeation of and oral sensitization to ovalbumin in mice.

An increase in plasma ovalbumin concentrations after intragastric administration of ovalbumin was suppressed by concomitant freeze-dried kefir in BALB/c mice. Serum levels of ovalbumin-specific immunoglobulin G and proliferation of splenic mononuclear cells in mice immunized orally with ovalbumin were suppressed by feeding freeze-dried kefir. We propose that kefir reduces intestinal permeation of food antigen, which contributes to suppression of oral sensitization.
