In addition to numerical changes of lymphocytes and monocytes of patients with cancer of the cervix uteri and patients treated with radiation therapy for cancer of the cervix uteri, PHA, PPD, and intractaneous reaction of Candida antigen of them were discussed. The subjects were 31 cases of normal group, 158 cases of cancer of the cervix uteri, and 35 cases which received radiation therapy with a dose of 6,000 R. The number of leukocyte significantly decreased after irradiation with 1,000 R as compared with that before irradiation, but marked decrease was not recognized irrespective of an increase of irradiation dose thereafter. The ratio of lymphocyte to leukocyte significantly decrease after irradiation with 2,000 R, and there were many cases with the ratio of under 20%. The number of lymphocyte significantly decreases after irradiation with 1,000 R, but the decrease was not recognized after irradiation with 2,000 R. The ratio of monocyte to leukocyte significantly increased in the irradiated group with 2,000 R and 3,000 R. With respect to intracutaneous reaction, a lowering of the reaction was recognized in general, and the reaction to non-specific antigen remained strongly. (Tsunoda, M.)

reduction in cervical cancer mortality is the ultimate goal of the screening. Quality of death certificate reports has been improved over time, but they are still inaccurate, making it difficult to assess time trends in mortality. to evaluate the accuracy of the topographic coding of causes of death and to estimate the mortality time trend for cervical cancer through the method of incidence-based mortality (IBM) using cancer registry (CR) data. from the mortality registry (MR), we extracted data on deaths for cervix uteri cancer, corpus uteri cancer, and uterus cancer not otherwise specified (NOS) referred to residents in Reggio Emilia (Emilia-Romagna Region, Northern Italy) from 1997 to 2013. Deaths were checked with the CR to verify the topographical site of the primary tumour. Furthermore, by using CR data, we constructed a cohort of incident cervical cancer cases diagnosed between 1997 and 2009 with a 5-year follow-up. We calculated cause-specific IBM (excluding ovary) and IBM for all cause, crude and standardized, and annual percentage change (APC). out of 369 deaths for uterine cancer, 269 were reported in the RT: 32 for cervix uteri cancer, 76 for corpus uteri cancer, 161 for uterus cancer NOS. 28 of the 32 persons who died for cervical cancer were incidents for cervix uteri cancer. 63 of the 76 who died for corpus uteri cancer were incidents for corpus uteri cancer. Of the 161 who died of uterus cancer NOS, 80 were incidents for corpus uteri cancer, 45 for cervix uteri cancer, 28 for uterus cancer NOS, 5 for vagina cancer, and 3 for cancer of other non-specified organs. Applying these proportions of misclassification, we can estimate that the real number of cervical cancer deaths is 2.4 folds the number of cases reported in the MR as cervical cancer. IBM for all causes decreased significantly over the years (APC: -9.5; 95%CI -17.1;-1.1); cause-specific IBM decreases, but not significantly (APC: -5.1; 95%IC -16.1;+7.3). There is no improvement in survival (r

Radical hysterectomy with pelvic lymphadenectomy is the treatment of choice for early-stage cervical cancer. Wertheim's original technique has been often modified, mainly in the extent of parametrectomy. Okabayashi's technique is considered as the most radical variant regarding removal of the ventral parametrium and paracolpal tissues. Surgical outcome concerning recurrence and survival is good, but morbidity is high due to autonomic nerve damage. While the autonomic network has been studied extensively, the lymphatic system is less understood. This study describes the lymphatic drainage pathways of the cervix uteri and specifically the presence of lymphatics in the vesico-uterine ligament (VUL). A developmental series of 10 human female fetal pelves was studied. Paraffin embedded blocks were sliced in transverse sections of 8 or 10 μm. Analysis was performed by staining with antibodies against LYVE-1 (lymphatic endothelium), S100 (Schwann cells), alpha-Smooth Muscle Actin (smooth muscle cells) and CD68 (macrophages). The results were three-dimensionally represented. Two major pathways drained the cervix uteri: a supra-ureteral pathway, running in the cardinal ligament superior to the ureter, and a dorsal pathway, running in the utero-sacral ligament towards the rectal pillars. No lymph vessels draining the cervix uteri were detected in the VUL. In the paracolpal parametrium lymph vessels draining the upper vagina fused with those from the bladder. The VUL does not contain lymphatics from the cervix uteri. Hence, the favorable survival outcomes of the Okabayashi technique cannot be explained by radical removal of lymphatic pathways in the ventrocaudal parametrium. © 2013.

Investigations of sexual consciousness and sexual dysfunction after radiotherapy for cancer of the cervix uteri were performed on patients of middle and old ages by questionnaires and questioning by doctors, and the following results were obtained. 1. Before radiotherapy, sexual activity was most prominent in their twenties and thirties. However, patients who were in fifties when this study was performed had most active sexual lives during the ages from 35 to 50 years. 2. Frequencies of sexual intercourse decreased markedly just before radiotherapy, and many patients received radiotherapy when sexual activity fell. 3. 32% of the patients have not experienced sexual intercourse after radiotherapy. 4. Decreases in the sex urge, sexuality, vaginal discharge, and frequency of sexual intercourse after radiotherapy were recognized in 77%, 77%, 70%, and 93% respectively. 5. Patients who became unwilling to maintain sexual lives after radiotherapy because of fear about recurrence or aggravation of cancer were 38% by questionaires and 49% by questioning by doctors. 6. Pains on sexual intercourse were found in 69% by questionaires and 49% by questionning by doctors. Most pains occurred at penis insertion and was thought to be due to atrophy and inflammation of vagina and external genitalia in most cases. 7. Both vaginal damage and sexual dysfunction in patients with radiotherapy following surgery for cancer of the cervix uteri, in patients with radiotherapy alone for cancer of the cervix uteri, and in patients with radiotherapy following surgery for cancer of the ovary and corpus uteri were marked, modest and mild, respectively. 8. Vaginal damage score was higher in patients treated more than 5 years before than those less than 2 years ago, but there were no differences in sexual dysfunction score between both groups.

This report describes a girl with congenital pouch colon (CPC), uterus didelphys with septate vagina, and a cloacal anomaly. The girl underwent cloacal reconstruction at the age of 15 months. Subsequently, at puberty, the child had primary amenorrhea with severe cyclic abdominal pain due to endometriosis of both the uteruses and adnexal cysts with hematometra and hematosalpinx. Laparotomy with removal of both uteri and the left fallopian tube was performed. Both uteri had atresia of the cervix uteri. This report emphasizes the need for comprehensive evaluation and a long-term management strategy for associated gynecologic anomalies in girls with CPC, especially with regard to patency of the outflow tract.

Over the past decade, stem cell research has emerged as an area of major interest for its potential in regenerative medicine applications. This is in constant need of new cell sources to conceive regenerative medicine approaches for diseases that are still without therapy. Scientists drew the attention towards alternative sources such as foetal adnexa and fluid, as these sources possess many advantages: first of all, cells can be extracted from discarded foetal material and it is non-invasive and inexpensive for the patient; secondly, abundant stem cells can be obtained; and finally, these stem cell sources are free from ethical considerations. Cells derived from foetal adnexa and fluid preserve some of the characteristics of the primitive embryonic layers from which they originate. Many studies have demonstrated the differentiation potential in vitro and in vivo towards mesenchymal and non-mesenchymal cell types; in addition, the immune-modulatory properties make these cells a good candidate for allo- and xenotransplantation. Naturally occurring diseases in domestic animals can be more ideal as disease model of human genetic and acquired diseases and could help to define the potential therapeutic use efficiency and safety of stem cells therapies. This review offers an update on the state of the art of characterization of domestic animals' MSCs derived from foetal adnexa and fluid and on the latest findings in pre-clinical or clinical setting of the stem cell populations isolated from these sources. © 2015 Blackwell Verlag GmbH.

The new classification system of uterine anomalies from the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy defines T-shaped and tubular-shaped infantilis uteri as 'dysmorphic'. Such malformations have been proven to be associated with poor reproductive performance. A prospective observational study was conducted with 30 infertile women with dysmorphic uterus who underwent the novel Hysteroscopic Outpatient Metroplasty to Expand Dysmorphic Uteri (HOME-DU ) technique. Incisions are made on the uterine walls with a 5 Fr bipolar electrode. The procedure was conducted in outpatients under conscious sedation, using a 5-mm office hysteroscope. The technique was successful in all cases without complications. A net increase of uterine volume was found, as measured at hysteroscopy and three-dimensional transvaginal ultrasound (P dysmorphic uteri. Although the cohort was small, pregnancy and live births outcomes were favourable in this poor-prognosis group, implying desirable benefits, which should be compared with other techniques.

Full Text Available The objective of this study was to describe the anatomic and histologic features of the Sapajus sp. eye, comparing similarities and differences of humans and other species of non-human primates for biomedical research purposes. Computed tomography (CT of adnexa, eye and orbit live animal, as well as formolized pieces of the same structures of Sapajus sp. for anatomical and histological study were also performed. The anatomical description of the eye and adnexa was performed using the techniques of topographic dissection and exenteration. Histological fragments were fixated in buffered formalin 10%, processed by the routine paraffin inclusion technique, stained with hematoxylin-eosin and special stains. CT scan evaluation showed no differences between the live animal and the formolized head on identification of visual apparatus structures. Anatomic and histologic evaluation revealed rounded orbit, absence of the supraorbital foramen and frontal notch, little exposure of the sclera, with slight pigmentation of the exposed area and marked pigmentation at the sclerocorneal junction. Masson's Trichrome revealed the Meibomian glands, the corneal epithelium and Bowman's membrane; in the choroid, melanocytes and Bruch's membrane were observed; and in the retina, cones and rods as well as, optic nerve, the lamina cribrosa of the nerve fibers bundles. Toluidine blue highlighted the membranes: Bowman, Descemet and the endothelium; in the choroid: melanocytes; and in the retina: nuclear layers and retinal pigment epithelium. In view of the observed results Sapajus sp. is an important experimental model for research in the ophthalmology field, which has been shown due to the high similarity of its anatomical and histological structures with the human species.

Dysplastic Ichthyosis Uteri-like changes of the entire endometrium associated with a squamous cell carcinoma of the uterine cervix

Full Text Available Abstract Ichthyosis uteri is an exceedingly rare condition in which the entire surface of the endometrium is replaced by stratified squamous epithelium. Originally described as an endometrial response to iatrogenically-introduced caustic substances, similar changes have since been described in association with a variety of inflammatory conditions of the endometrium. We describe herein a heretofore undescribed example of a moderately differentiated squamous cell carcinoma of the uterine cervix associated with extensive ichthyosis uteri-like changes of the entire adjacent endometrium. Additionally, the squamous epithelium of the latter also showed multifocal changes diagnostic of a low-grade squamous intraepithelial lesion. The potential genesis of this composite of findings is discussed, as is the neoplastic potential of ichthyosis uteri. It is concluded that a squamous cell carcinoma of the cervix extended proximally into the endometrium, and that there was a colonization of a pre-existing ichthyosis uteri by associated human papillomavirus. The possibility of significant cervical pathology should be considered when plaques of squamous epithelium with low grade dysplastic changes are identified in an endometrial biopsy or curettage.

The relationship among the incidence, the time of occurrence, and radiation dose was studied in regard to hemorrhagic cystitis after radiotherapy for carcinoma of the cervix uteri. Of 1004 patients with carcinoma of the cervix uteri observed between 1961 and 1974, 28 (2.8%) had bladder hemorrhage seemingly due to radiation injury (0.7% were serious). Incidences varied every year. The radiation dose was increased from 4000 to 6000 rad after 1971. In addition to this external dose, because the depth-dose has also increased, the rate of bladder hemorrhage has become high. Seven patients with serious bladder hemorrhage were exposed to more than 5000 rad of 60 Co. Bladder hemorrhage occurred comparatively frequently in patients in whom two hila were irradiated. It usually occurred a few years after irradiation (about 1 year after initial rectal hemorrhage). It continued for approximately 1 year in 21 patients, for approximately 3 years in 4 patients, and for approximately 4 years in 3 patients. Adrenochrome (a hemostatic agent) and antiplasmin were used as therapeutic agents. Serious patients improved remarkably when a large amount of diluted formaline solution or conjugated estrogen was administered intravenously. (Namekawa, K.)

The results of radiotherapy of 374 cases of cancer of the cervix uteri, 163 cases of carcinoma of the endometrium, 24 cases of cancer of the cervival stump and 16 cases of sarkoma of the uterus carried out during the years 1967 to 1972 are shown. The absolute 5-year cure rates in our case material were 60,4 % for cancer of the cervix uteri and 73,0 % for carcinoma of the endometrium. In comparison with the treatment results reported in the years 1962 to 1966 an increase in radiotherapeutical efficiency was found, amounting to 8,8 % in case of cancer of the cervix uteri and 13,2 % in case of carcinoma of the endometrium. We also compared and analysed the different cure rates in case of primary irradiation (52,6 % resp. 55,8 %) as opposed to postoperative radiotherapy '76,9 % resp. 81,1 % cure rates). The frequency of radiation injuries and the rate of recurrence or metastases, as well as the incidence of concomitant diseases and complications have been reported and compared with those of other clinics.

2012-01-01

Full Text Available Extraskeletal myxoid chondrosarcoma is a rare soft-tissue sarcoma, mostly occurring in the proximal extremities and limb girdle. Majority of the patients are in fifth and sixth decades of life with male preponderance. We report here a case of primary extraskeletal myxoid chondrosarcoma of the uterine adnexa involving the broad ligament and fallopian tube synchronously without any evidence of uterine/ovarian involvement in a young multiparous female of 27 years. After the histopathological diagnosis, re-excision of the tumor bed with wide local margins was recommended. Since the tumor has an aggressive course, with propensity for late recurrence and metastases to lungs, the patient must be considered for long-term follow-up.

The principle of the therapy of carcinoma cervicis uteri in the Research Institute of Clinical and Experimental Oncology in Brno is the combination of betatron megavoltage irradiation and cobalt 60 irradiation with intracavital radium irradiation. On the basis of many years' study concerning the therapy and therapeutic results of this tumor accurate directions of total therapy were elaborated. Carcinoma is diagnosed and classified precisely according to valid international directions. In addition to basic examination, limb lymphography was introduced giving the strategy of irradiation when lymphatic system is involved and in early stages of the disease. By preliminary evaluation of the obtained data a certain improvement of therapeutic results is proven. About 15% more patients are alive till 5 years without any signs of the disease than in precedent years. In spite of a high dose summation given by the extent of megavoltage irradiation the number of postirradiation reaction, nor early late, is increased to much. Complex therapy of this tumor is performed by a team of physicians composed of gynecologist, radiologist, rentgendiagnosticist, pathologist, and radiation physicist. By increasing the number of cured patients and their return and enclosure into further working process the savings in state budget are achieved. The effectiveness of the carcinoma cervicis uteri therapy is therefore dependent not only on earlier diagnosis and modern irradiation technique, but also on the cooperation of a team of physicians who plan, perform and follow the therapy.

To report the outcomes of laparoscopic metroplasty in bicornuate and didelphic uteri. This observational study includes 26 women with double uterine cavities (22 bicornuate and 4 didelphic uteri) with history of recurrent pregnancy loss undergoing laparoscopic metroplasty, second-look laparoscopy and hysteroscopy between 2008 and 2013 in University and Private hospital (Shiraz, Iran). The feasibility of laparoscopic metroplasty, appropriateness of the uterine cavity upon second-look laparoscopy, pregnancy outcome and live birth rate (within at least 12 month follow-up) were evaluated. All patients had a unified and acceptable uterine cavity in second-look operation. Minimal pelvic adhesions in eight cases and subseptum of uterus in seven patients were detected which were removed by laparoscopy and resectoscopy, respectively. Out of 14 patients who could be followed for one year for pregnancy occurrence 12 patients had conception. Out of them nine term pregnancies with normal pregnancy and delivery outcomes were reported. These women delivered nine live neonates through the cesarean section. Three patients had pregnancy loss (2 early pregnancy losses and one with preterm delivery). Two patients decided to postpone conception due to personal reasons. Laparoscopic metroplasty by developing single uterine cavity with a suitable volume and minimal adhesion formation can be a substitute for laparotomy technique. However, more long-term studies should be done on larger sample size to confirm its positive effects on the pregnancy outcomes.

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008.

Cervix uteri. Strategy for the management of cancer of the cervix uteri

International Nuclear Information System (INIS)

Takahashi, S.

In our department external irradiation is given priority over intracavitary (radium) therapy for the treatment of carcinoma of the cervix uteri. Our policy is to irradiate the volume containing the primary lesion, parametrium and pelvic lymph nodes to a dose of 40.0 Gy in about 4 weeks for stages I and IIa, or 50.0 Gy over 5 weeks for stages IIb and III. For stages I and IIa, intracavitary radium therapy is additionally given to a dose of 28.0-30.0 Gy at ''point A'', 7-10 days after the external irradiation, by means of two fractions with an interval of 7-10 days. For stages IIb and III, further external irradiation is carried out to give an additional dose of 20.0 to 25.0 Gy to the cervix and parametrium over 2 weeks by means of radiation fields of reduced size. If the size of the tumour in stages IIb and III is considerably reduced after the initial dose of 50.0 Gy, and the dose to point A is 40.0 Gy, intracavitary therapy is carried out without the additional small field irradiation. The intracavitary therapy is given twice with an interval of 8 days. For stage IV without distant metastases the treatment policy is the same as that in stage III; for stage IV with distant metastases, only whole pelvis irradiation is performed, to a dose of 50.0 Gy over 5 weeks

Estrogen influences dolichyl phosphate distribution among glycolipid pools in mouse uteri

Carson, D.D.; Tang, J.; Hu, G.

1987-03-24

To determine the role that dolichyl phosphate availability plays in this induction, the authors studied the effects of estrogen priming on the content of dolichyl phosphate and the distribution of dolichyl phosphate among various glycolipids in uteri. Dolichol-linked saccharides were metabolically labeled to equilibrium with either (/sup 3/H)glucosamine or (/sup 3/H)mannose and extracted from primary explants of uterine tissue. The amount of dolichol-linked saccharide was calculated from the specific radioactivity determined for the corresponding sugar nucleotides extracted from the tissues. The major dolichol-linked saccharides identified were mannosylphosphoryldolichol (MPD), oligosaccharylpyrophosphorydolichol (OSL), and N,N'-diacetylchitobiosylpyrophosphoryldolichol (CBL). Estrogen increased the levels of MPD and OSL 4-fold; however, CBL levels did not change. After 3 days of treatment, the levels of these glycolipids were very similar to those in uteri from pregnant mice. The specific activity of GPD synthase was similar under all conditions studied. These studies provide the first determination of the levels of dolichol-linked saccharides in tissues and how these levels change during hormonal induction of glycoprotein assembly. Coupled with earlier studies, the present work demonstrates that among a number of key points of N-linked oligosaccharide assembly and transfer only synthesis of MPD increases coordinately with the increase observed in lipid- and protein-linked oligosaccharide assembly that occurs in vivo in response to estrogen. They suggest that control of MPD levels is an important regulatory aspect of N-linked glycoprotein assembly in this system.

This study evaluated the survival outcome, pattern of failure and prognostic factors in cervix uteri cancer patients. We reviewed the data of 60 patients with stages IB-IVA cancer who were treated between January 2004 and December 2010. Most patients (n = 50; 83%) had squamous cell carcinoma. Stage IIB was the most common presentation (n = 41; 68%). Forty-seven patients (78%) received Cisplatin concurrent with radiotherapy (CRT). The 2- and 4-year overall survival (OS) was 82% and 79%, respectively. Prolongation of the overall treatment time (OAT) for greater than 56 days, advanced stage and pretreatment hemoglobin (Hb) levels (cervix uteri cancer patients and the prognostic factors are comparable to those of previous reports. Orthogonal brachytherapy planning and vaginal infiltration negatively predicted relapse. © 2016 John Wiley & Sons Australia, Ltd.

The investigation has indicated the presence of adrenergic and cholinergic autonomic nerve terminals (ANT) in the tissues of squamous cell carcinomas of the cervix uteri in a tumor growth area and contralaterally. Heterogeneity of the local neuromediator background in the tumor growth area and contralaterally may be explained, by studying the specific features of the cell microenvironment of ANT.

The ''afterloading'' technique with use of Curietron (41 cases) or Selectron (43 cases) apparatus was applied in 83 cervix uteri carcinoma patients in phase 1b (79 cases) and 2a (4 cases). The Wertheim-Magis operation was performed after several weeks. Post-operative histologic investigation showed complete destruction of the tumour in 72% cases; persistent cancer cells in cervix uteri were stated in 11 patients (13%), while lymphatic node metastasis was seen in 14 patients (17%). Supplementary teleradiotherapy was performed in those cases. 39 patients (95%) of the 41 observed during 3 years survived without any cancer symptoms. No explicit relationship between dose administered to vaginal disc and cancer persistence frequency in the cervix uteri was stated. However, such relationship was stated for the dose in point A. In the group of 19 patients who received point A dose of the least 6000 rads, with average TDF value of 135, presence of cancer cells in cervix uteri was not stated in any of the cases. In 7 patients (17%) observed for over 3 years light and medium heavy postradiation complications were stated; in that 5 rectum side complications were stated in patients additionally irradiated from external fields, where the dose absorbed by rectum wall exceeded 8000 rads, with TDF - 150. No complications were observed when the dose was less than 5000 rads and TDF below 100. 16 refs., 1 fig. (author)

Cytologic findings of glandular lesions of the cervix uteri are often difficult to evaluate. We studied the usefulness of CINtec PLUS p16/Ki-67 double stain (mtm laboratories, Heidelberg, Germany) for the diagnosis of glandular lesions. The study included 47 abnormal results on liquid-based cytologic tests with a subsequent histologic diagnosis of adenocarcinoma in situ or with early invasion, and 16 samples with negative results on follow-up. All samples were stained with CINtec PLUS p16/Ki-67 double stain. Of the neoplastic samples, 7 were excluded because of insufficient residual cellularity or loss of neoplastic cells. Of the samples that were adequate, 92.5% were stained with CINtec PLUS, whereas 7.5% were judged inconclusive. All inconclusive cases were at least 3 years old. Of the 16 negative samples, 15 (93.8%) stained negative and only 1 (6.2%) showed several positive clusters of cells. Our study shows that CINtec PLUS is a robust and useful tool for the diagnosis of glandular lesions of the cervix uteri.

In two different experiments, the effects of hyperthyroidism on the histomorphometry and expression of Cdc47 and caspase-3 were evaluated in the uteri and placentas during gestation and postpartum. Fetal development was also evaluated during gestation. In the first experiment, 36 adult female Wistar rats were divided into two groups of 18 animals each: (1) hyperthyroid; and (2) euthyroid (control). Female rats were mated and killed at 7, 14 and 19 days of gestation. Uteri and placentas were weighed and subjected to histomorphometric and immunohistochemical evaluation to determine the expression of Cdc47 and caspase-3. Ovaries were also evaluated for weight and subjected to morphometric analysis. Fetuses were quantified and weighed individually. In the second experiment, 12 adult female Wistar rats were divided into two groups of six animals each: (1) hyperthyroid; and (2) euthyroid (control). Female rats were mated and killed 2 days postpartum. Uteri were evaluated in the same way as for the first experiment. Hyperthyroidism increased ovulation and conception rates without disturbing the size and viability of the fetuses. In the pregnant uteri, hyperthyroidism did not change the thickness of the layers or the expression of Cdc47 and caspase-3. However, in the placentas, hyperthyroidism increased the medium diameter of trophoblast cells, as well as the thickness and the expression of Cdc47 of spongiotrophoblast cells, at 14 days of gestation. During uterine involution, hyperthyroidism significantly increased the expression of Cdc47 and reduced the expression of caspase-3 in the uterine layers. In conclusion, hyperthyroidism increased the conception rate because of an ovulation gain, induced significant placental changes during pregnancy and, in the uterus, increased Cdc47 expression and decreased caspase-3 expression after parturition.

Pretumoral changes in the epithelium of the cervix uteri include cervical intraepithelial neoplasia (CIN). CIN III should be differentiated with regenerative changes during epidermization of endocervicoses. Epidermization is proliferation of undifferentiated reserve cells that differentiate towards the squamous epithelium, by superseding the ectopic endocervical glandular epithelium. This process was called immature squamous metaplasia (ISM). The objective of the investigation was to define the significance of different morphological signs in the differential diagnosis of CIN III and ISM. One hundred and twelve cervical, CIN III, and immature squamous metaplasia biopsies were selected for examination. The selected cervical specimens were divided into 2 groups according to the presence or absence of p16 and CK17 expression. The p16+, CK17- cases were taken as true CIN III and the pl 6-, CK17+ as a regenerative process. The basis for this investigation is the signs included by O.K. Khmelnitsky into an algorithm for the differential diagnosis of epidermizing pseudoerosion and intraepithelial cancer of the cervix uteri. The algorithm was reconsidered to objectify. The investigation established great differences in the number of significant mitoses in the study groups. A clear trend was found for differences in the number of acanthotic strands. A new differential diagnostic algorithm for CIN III and ISM, which included the number of significant mitoses and acanthotic strands and p16 and CK17 expression, was proposed.

We present a case of successful pregnancy after effective uterovaginal anastomosis in a 26-years-old patient with congenital atresia of the cervix uteri. She spontaneously achieved pregnancy after four years of uterovaginal anastomosis. Gestation was at the eighth lunar month and the delivery was done by cesarean section due to rapidly progressing fetal asphyxia. The patient gave birth to a live healthy male, weighing 1,950 g, with an Apgar score of 5 and 8 at 1 and 5 min, respectively. The postoperative course was uneventful, and leakage of lochia was normal.

Torsion of normal adnexa in a 31-year-old woman: A case report and literature review

Full Text Available It is known that a large ovarian cyst will likely cause torsion. However, normal adnexal torsion is rare and occurs in premenarchal girls in most cases. This is a case of a reproductive woman. A 31-year-old woman suffering from acute abdominal pain in the lower and right side consulted her gynecologist. The next day she had a computed tomography performed and was suspected of ovarian torsion. She did not have fever, nausea, or leukocytosis, but her abdominal pain persisted. Diagnostic laparoscopy was performed and showed torsion of the right fallopian tube, which was swollen and looked like a hydrosalpinx with a normal ovary. We did detorsion and excision of the right tube. However, pathological findings showed that the right tube was not a hydrosalpinx but was swollen due to blood stasis. We determined that this case was torsion of normal adnexa. In such cases, diagnostic laparoscopy is very effective.

Functional anatomy and immunological interactions of ocular surface and adnexa.

Science.gov (United States)

Paulsen, Friedrich

2008-01-01

This chapter gives an overview about the structures and physiology of the ocular surface and its adnexa and focuses in a second part on the possible meaning of eye-associated lymphoid tissue (EALT) in a context with the development of dry eye. Sections deal with (1) anatomy of the ocular surface, lacrimal gland, eyelid and nasolacrimal ducts. (2) The meaning and importance of the lacrimal functional unit and the function of the mucosal innate immune system are briefly summarized. (3) Finally, the occurrence and the possible function of EALT is discussed with regard to tolerance induction and dry eye. The epithelial surface of the eye and its specialized glandular infoldings produce the components of the tear film, which include water, protective antimicrobials, cytokines, lipids as well as mucins and trefoil factor family (TFF) peptides. Antimicrobials, mucins and TFF peptides perform a number of essential functions which, collectively, provide protection of the ocular surface. Their production changes in cases of dry eye. The development of EALT is a common feature frequently occurring in symptomatically normal conjunctiva and nasolacrimal ducts. The production of antimicrobials, mucins and TFF peptides can be linked with cell signaling, tear film rheology, and antimicrobial defense at the ocular surface. Changes in the production of such peptides and proteins in cases of dry eye support the assumption that these peptides and proteins are involved in the pathophysiological events that occur at the ocular surface and lacrimal apparatus. Whether special types of bacteria, viruses, or other factors, e.g., immune deviation, are responsible for the development of EALT in humans requires further investigation in prospective and experimental studies.

Purpose: Postoperative radiation is often indicated in the treatment of malignant epithelial tumors of the orbit and ocular adnexa. We present details of radiation technique and toxicity data after orbit-sparing surgery followed by adjuvant proton radiation therapy. Methods and Materials: Twenty patients underwent orbit-sparing surgery followed by proton therapy for newly diagnosed malignant epithelial tumors of the lacrimal gland (n=7), lacrimal sac/nasolacrimal duct (n=10), or eyelid (n=3). Tumor characteristics, treatment details, and visual outcomes were obtained from medical records. Acute and chronic toxicity were prospectively scored using Common Terminology Criteria for Adverse Events version 4.0. Results: The median radiation dose was 60 Gy(RBE) (relative biological effectiveness; [range 50-70 Gy]); 11 patients received concurrent chemotherapy. Dose to ipsilateral anterior optic structures was reduced in 13 patients by having them gaze away from the target during treatment. At a median follow-up time of 27.1 months (range 2.6-77.2 months), no patient had experienced local recurrence; 1 had regional and 1 had distant recurrence. Three patients developed chronic grade 3 epiphora, and 3 developed grade 3 exposure keratopathy. Four patients experienced a decrease in visual acuity from baseline but maintained vision sufficient to perform all activities of daily living without difficulty. Patients with grade ≥3 chronic ocular toxicity had higher maximum dose to the ipsilateral cornea (median 46.3 Gy[RBE], range 36.6-52.7 Gy[RBE] vs median 37.4 Gy[RBE], range 9.0-47.3 Gy(RBE); P=.017). Conclusions: Orbit-sparing surgery for epithelial tumors of the orbit and ocular adnexa followed by proton therapy successfully achieved disease control and was well tolerated. No patient required orbital exenteration or enucleation. Chronic grade 3 toxicity was associated with high maximum dose to the cornea. An eye-deviation technique can be used to limit the maximum

An analysis of the results of radiotherapy of 951 patients with cancer of the lower lip, larynx and cervix uteri on the basis of the concept of a single optimum curative dose (OCD 1 ) is presented. The best long-term results (in good health for 3 years and more) were obtained for T 1 Stage with summary focal doses that were equivalent to OCD 1 : 98% for the lowel lip, 95% for the larynx, and 93.9% for cervix uteri. It has been shown that OCD 1 estimated for identical tumor volumes (1 cm 3 ) taking account of the character of fractionation and dose rate for all known sites is practically the same - about 24 Gy. It has been demonstrated that to reach a maximum effect with the growth of tumor volume, the summary curative dose should be increased; however, of common knowledge is that under the conditions of γ-beam therapy by simple fractionation the summary focal doses cannot exceed 60-80 Gy. The above doses can result in a radical effect in tumor volumes not more than 5-6 cm 3 . This tumor volume is regarded as a maximum one for cure of malignant epithelial tumors. In large volume tumors one should rely upon palliative radiotherapeutic results [ru

Factors for a Successful Laparoscopic Hysterectomy in Very Large Uteri

Full Text Available Minimally invasive hysterectomy is a standard procedure. Different approaches, as laparoscopically assisted vaginal hysterectomy, vaginal hysterectomy, and subtotal and total laparoscopic hysterectomy, have been described and evaluated by various investigations as safe and cost-effective methods. In particular, in comparison to abdominal hysterectomy, the minimally invasive methods have undoubted advantages for the patients. The main reason for a primary abdominal hysterectomy or conversion to abdominal hysterectomy during a minimal invasive approach is the uterine size. We describe our course of action in the retrospective analysis of five cases of total minimal-access hysterectomy, combining the laparoscopic subtotal hysterectomy and the vaginal extirpation of the cervix in uterine myomatosis with a uterine weight of more than 1000 grams, and discuss the factors that limit the use of laparoscopy in the treatment of big uteri.

Analytic study of regional changes in carcinoma of the cervix uteri following linac irradiation, 3

International Nuclear Information System (INIS)

Yamashita, Michitaka

1977-01-01

To observe regional changes following Linac irradiation therapy for 15 patients with carcinoma of the cervix uteri, an electron microscopic study of the carcinomatous cells of a parabasal type was made, and the following conclusion was obtained. Early changes which were seen following 1000 R irradiation were an appearance of various lysosomes and a remarkable appearance of the Golgi's apparatus. Some other changes were noted in mitochondria, vesicles, and free ribosomes, while very slight changes in the nuclei. After 2000 R irradiation, the foregoing early changes and a tendency of cells separated became more distinctive. Following an irradiation of 3000 R, changes were noted in the nuclei, destruction of the nuclear membrane and agglutination of chromatin being prominent. Glycogen granules were also noted. After an irradiation of 4000-5000 R, the carcinomatous cells were necrotized and ill-defined. There were remarkable destructions of the nuclei and intracellular organellas. On the basis of the foregoing findings, it is considered that the effect of irradiation on the carcinomatous cells of a parabasal type in carcinoma of the cervix uteri appears as a change in the cytoplasm which is followed by the destructive change of the nuclei. A difference in the effect of irradiation was conspicuous in the changes of the lysosome. In remarkably effective cases, there occurred an early appearance and an early inactivation of the lysosome. However, in ineffective cases, those changes appeared after receiving 1000 R more irradiation. (Ueda, J.)

To investigate the distribution of lymphatic tissues and nerves in the supporting ligaments around the cervix uteri for their tomographical relationship, 9 adult female cadavers were used in this study. Following the incision of all supporting ligaments around the cervix, hematoxylin and esosin (H&E) and immunohistochemical staining of various sections of these ligaments was performed to enable the distribution of lymph tissues and autonomic nerves to be observed. Four lymph nodes were identified in three cadaver specimens. Three lymph nodes were present at a distance of 2.0 cm from the cervix in the cranial side of the cardinal ligaments (CLs), and one lymph node was located at a distance of 4.0 cm from the cervix in the cranial side of the uterosacral ligament (USL). The lymphatic vessels were dispersed in the CLs, scattered in the cervical side of the USLs, and occasionally distributed in the vesicouterine ligaments (VULs). In the CLs, parasympathetic nerves were located at the pelvic lateral wall and went downwards and medially into the cervix, while sympathetic fibers were located in the middle and lower parts of the ligaments. In the USLs, the autonomic nerves, which consisted primarily of sympathetic fibers, went downwards and laterally from the pelvic wall to the cervix. In the VULs, parasympathetic and sympathetic nerves were located in the inner sides of the vesical veins in the deep layers of the ligaments. It is concluded that there are few lymphatic tissues in the supporting ligaments around the cervix uteri, and that nerve‑sparing radical hysterectomy (NSRH) may be a safe method for the treatment of early‑stage cervical cancer.

Kasamatsu, Tatsuhiro

1977-01-01

Scheriproct suppository was used in 25 cases of radiation rectal hemorrhage induced after a little while from irradiation to the patients with cancer of the cervix uteri. As to the stage of cancer of the cervix uteri at the first administration of this drug, the first stage was 2 cases, the second stage, 10, and third stage, 13. The age of the patients ranged from 30 to 70 years old. The administration to severe cases was performed 1-2 times per a day, and, when severe cases were improved, the administration was performed once per a day. When the stage of disease was improved further, this drug was used only for hemorrhage. With respect to the degree of hemorrhage when the administration started, 17 cases did not induce anemia (+), and 8 cases needed to be administered iron (++). As a result of administration of this drug, 20 cases showed decrease of the amount of hemorrhage, 4 cases did not show any change, and one case showed aggravation. In 17 cases of (+), 14 cases showed decrease of hemorrhage, 2 cases showed no change, and one case showed aggravation. In 8 cases of (++), 6 cases showed decrease of hemorrhage, and 2 cases were unchanged. 11 cases showed decrease of hemorrhage within 3 months after the administration, 7 cases, within 3 to 6 months, 1 case, within 6 to 9 months, and 1 case, within 9 to 12 months. One case of aggravation changed from (+) to (++) after five months of the administration, but further aggravation was not recognized. (Kanao, N.)

Sonographic recognition of three cases of septate uteri diminishes failures of quinacrine sterilization.

Using sonography, the bicornate and septate uterus as causes of failure of quinacrine sterilization (QS) are explored. Whether QS can be effectively performed on women with a bicornate or septate uterus is a question answered by a presentation of three such cases. Three cases presented were part of a prospective nonrandomized study of QS in 205 women requesting sterilization at the Family Planning Clinic, School of Medicine of the Federal University of Minas Gerais, Belo Horizonte, Brazil. Sonography was performed on all patients before, during and after QS. Quinacrine was packaged as seven pellets in a modified Copper-T IUD inserter (Sipharm, Sisseln, Switzerland). Each woman received the first transcervical insertion of 252 mg of quinacrine during the follicular phase of the menstrual cycle, usually immediately after menses. One month later, a second insertion was similarly performed. Patients were advised to use an alternate method of birth control for 12 weeks to allow time for scarring of the oviducts. A blood pregnancy test was done before the QS procedure. The diagnosis of a septate or bicornuate uterus was made by sonography in three of the 205 patients in the study. It was obvious that quinacrine had to be inserted into the two horns of such an anomalous uterus if the dissolved drug was to enter both fallopian tubes. Quinacrine dissolved into "lakes of quinacrine," and sonographically could be seen at the top of the uterine fundus. For this clinical trial of 205 patients, there were 546 woman-years of follow-up, and the Pearl index was 0.73 per 100 woman-years (95% confidence limits: 0.02, 1.4). The bicornate or septate uterus can be a cause of failure of QS if undetected. Advantages of sonography prior to, during and after QS are apparent in the three patients with septate uteri. Sonography is advantageous when performing QS by demonstrating an anomaly of the uterus, which required separate insertions of quinacrine into each horn of a septate uterus and

Cancer of the cervix uteri (CCU) ranks third in the incidence of malignancies in women. The choice of CCU treatment mainly depends on the extent of the tumor process, i.e., the stage of the disease. Determining the stage of CCU is based on the clinical classification of the International Federation of Gynecology and Obstetrics (FIGO) (2009) and has a number of substantial limitations in evaluating parametrial invasion, tumor spread to the pelvic wall, and involvement of regional lymph nodes and in determining the true tumor sizes. Magnetic resonance imaging (MRI) is now the method of choice in staging invasive CCU. Multiparameter MRI will be able to enhance the efficiency of diagnosing microinvasive CCU as well (FIGO 2009), to plan surgical and/or chemoradiation treatment, to evaluate its efficiency, and to diagnose locally recurrent CCU.

Data on studying stomach motor function in patients with carvix uteri carcinoma of 2 and 3 stages in combined radiotherapy are given. The patients were examined before radiotherapy and directly after it as well as in 1-2 years using the X-ray method for 50 patients and electrogastrography for 68 patients. Revealed changes in stomach motor function, being considered as a response to irradiation, were manifested more often in decreasing motility, evacuatory function and bioelectric stomach activity. These functional changes result in disturbance of general state of patients, appearance of symptomatology of stomach dysfunction and serve as indications for the prescription of correcting therapy, which includes diet and preparations strengthening stomach motor activity

It is very difficult to identify stromal invasion when the glandular epithelium of the cervix uteri is involved. It is necessary to draw a clear distinction between its glandular structures and adenocarcinoma in situ, involving the preexisting crypts and invasive glands. An attempt was made to assess the possibilities of using as markers of invasion the following stromal proteins and adhesion molecules: CD44, E-cadherin, beta-catenin, tenascin, and laminin. Fifty-three cases of benign glandular changes, 66 cases of dysplasias and adenocarcinomas in situ, and 47 cases of invasive adenocarcinoma were examined. An immunohistochemical study was performed according to the standard protocol using the antibodies to CD44, laminin, tenascin, E-cadherin, and beta-catenin and a semiquantitative assessment of results was made. CD44 was found to be redistributed from the cells to the tumor stroma. CD44 was not detected in the stroma surrounding the intact glands, so were benign epithelial changes. In the tumor environment, there was, on the contrary, a reaction with CD44 in 74.5% of invasive adenocarcinomas cases (p 0.05). CD44 and tenascin are of great diagnostic value in examining invasive and microinvasive adenocarcinomas of the cervix uteri. E-cadherin and beta-catenin are of no diagnostic value in the study groups of pathological processes. Laminin is a potential marker of stromal invasion; however, its expression calls for further investigation.

Hysterectomy for enlarged uteri is a surgical challenge. Our aim was to compare perioperative outcomes, cosmesis, and postoperative quality of life following laparoscopic hysterectomy for large uteri using minilaparoscopic 3-mm versus conventional laparoscopic 5-mm instruments. We prospectively enrolled women with a uterus between 16 and 20 weeks of gestation at the preoperative examination. These patients underwent laparoscopic procedures using either 3-mm (minilaparoscopy group) or 5-mm (standard laparoscopy group) instruments. Five months after surgery, patients were called back to fill out the validated Italian translation of the Short Form 12-item Health Survey. Data about the cosmetic outcome of the procedure were also collected, using a Numeric Rating Scale (NRS) from 0 to 10. Seventy-eight women were included (27 in the 3-mm and 51 in the 5-mm groups). Perioperative characteristics were comparable between groups. The median uterus weight was 575 (range, 440-1050) g and 550 (400-1000) g in the 3-mm and 5-mm groups, respectively. No minilaparoscopic procedure was converted to standard 5-mm or to an open approach. One (2%) conversion to open abdominal surgery was needed in the conventional laparoscopy group. A better subjective cosmetic outcome was found in the 3-mm (NRS, 9.7 ± 0.4) versus the 5-mm (NRS, 8.9 ± 1.2) group (P=.01). Postoperative quality of life was comparable between groups. Minilaparoscopic hysterectomy is feasible, even in the case of an enlarged-size uterus. Moreover, it is associated with a better cosmetic outcome, compared with conventional laparoscopy.

In addition to B-28 relaxin (relaxin B) and B-32 relaxin, acid-acetone extracts of porcine ovaries contain relaxin C, which differs both chemically and biologically from the others. Relaxin C contains one proline residue and a single tryptophane residue; it is about half as active as relaxin B in the guinea pig assay, is active in the motility inhibition assay, but is essentially completely inactive in the mouse pubic ligament assay. Relaxin B has been shown to exhibit protein anabolic properties in rat uteri. To compare the effects of relaxins B and C on uterine protein synthesis, ovariectomized, estrogen-primed mice were given relaxin B or C (10-100 μgm/100 gm b.w. in 1% benzopurpurine 4B) and the uptake of 3 H-proline into uterine protein measured in vitro and in vivo 3-12 hours later. Both relaxins induced significant (40-100%) increases in proline incorporation rates. Maximal stimulation of soluble protein synthesis occurred 3 hr after administration of either relaxin; in contrast, peak uptake of proline into uterine collagen occurred after 6 hr. Stimulation of collagen synthesis was more pronounced as well as more prolonged than the synthesis of soluble protein. Larger doses of relaxin C (as compared to B) were required for continued enhancement of collagen synthesis

Radiolesions of the pelvic bones (excluding the femur) were observed in 29 patients after irradiation therapy for cervix uteri cancer. Three regions can be affected corresponding to the areas irradiated: the sacrum and internal part of the iliac wings, the pubis, and the cotyles. In most cases the lesions appeared after 1 to 4 years. Their radiological appearances are characteristic, the principal sign being irregular bone condensation in a demineralized bone, without true cavitation. The only lytic lesions observed were in the pubis. Calcification of soft tissues may occur and fractures are frequent. There is a slow progression of the lesions over long periods. Clinical, radiological, and progression signs differentiate radiolesions from other affections: metastases, invasion by contiguity, infections, and radio-induced sarcoma [fr

To assess the effects of radiotherapy on immune status, a wide range of assessments have been performed on patients with localized carcinoma of the cervix uteri undergoing and initially responding clinically to radical pelvic radiotherapy. neutrophil function was essentially unchanged by treatment. Absolute neutrophil and lymphocyte counts fell after treatment and remained depressed 3 and 12 months following treatment. The proportions of T and B cells dropped with treatment but recovered to near-presentation levels during the follow-up period even though absolute counts remained depressed. In vitro tests of cellular immunity were depressed by treatment and remained so 3 and 12 months following treatment whereas skin test responses remained normal throughout the assessments. Inhibitory plasma effects were observed in photohaemagglutinin lymphocyte transformation studies on 4 untreated patients; at follow-up these effects were not evident. A variable response in immune indices has therefore been observed in patients in remission after treatment of localized carcinoma cervix stressing the importance of assessing several aspects of immune function and implying that persistent depression of certain indices does not adversely affect the host tumor response. In two patients relapsing after apparently good initial response, all aspects of immunological assessment (except serum immunoglobulin levels and neutrophil function) deteriorated

Although the diagnostic criteria of in-situ and invasive adenocarcinomas of the cervix uteri are well established, the differentiation from benign mimics may be difficult and the morphologic features of the precursors of endocervical adenocarcinoma are still debated. In this study, we evaluated the usefulness of p16ink4a (p16), ProEX C, and Ki-67 for the diagnosis of endocervical adenocarcinoma and its precursors. Immunohistochemistry with p16, ProEX C, and Ki-67 was performed in 82 glandular lesions including 15 invasive adenocarcinomas, 29 adenocarcinomas in situ (AIS), 22 non-neoplastic samples, and 16 cases of glandular dysplasia (GD), which showed significant nuclear abnormalities but did not meet the diagnostic criteria for AIS. The immunohistochemical expression pattern was scored according to the percentage of the stained cells (0, 1+, 2+, and 3+ when 0% to 5%, 6% to 25%, 26% to 50%, and more than 50% of the cells were stained, respectively) and was evaluated for each antibody. p16 was at least focally expressed (1+ or more) in 14 of 15 invasive adenocarcinomas, in all AIS and in 7 negative samples. ProEX C and Ki-67 both scored 1+ or more in all adenocarcinomas and AIS and in 8 and 6 negative samples, respectively. Of the GD 15, 14, and 15 expressed p16, ProEX C, and Ki-67, respectively. The score differences between neoplastic and non-neoplastic samples were highly significant for each marker (Pcervix uteri and may also improve the diagnostic accuracy of endocervical GD. In particularly problematic cases, the combination of p16 and a proliferation marker can provide additional help for the interpretation of these lesions.

Cervical uterine epithelial cells maintain a physiological and pathogen-free milieu in the female mammalian reproductive tract and are involved in sperm-epithelium interaction. Easily accessible, differentiated model systems of the cervical epithelium are not yet available to elucidate the underlying molecular mechanisms within these highly specialized cells. Therefore, the aim of the study was to establish a cell culture of the porcine cervical epithelium representing in vivo-like properties of the tissue. We tested different isolation methods and culture conditions and validated purity of the cultured cells by immunohistochemistry against keratins. We could reproducibly culture pure epithelial cells from cervical tissue explants. Based on a morphology score and the WST-1 Proliferation Assay, we optimized the growth medium composition. Primary porcine cervical cells performed best in conditioned Ham's F-12, containing 10% FCS, EGF and insulin. After cultivation in an air-liquid interface for three weeks, the cells showed a discontinuously multilayered phenotype. Finally, differentiation was validated via immunohistochemistry against beta catenin. Mucopolysaccharide production could be shown via alcian blue staining. We provide the first suitable protocol to establish a differentiated porcine epithelial model of the cervix uteri, based on easily accessible cells using slaughterhouse material.

Purpose: A retrospective study was performed to investigate the relationship between spontaneous apoptosis and angiogenesis uterine cervix squamous cell carcinoma patients. The prognostic value of each (and both) of these biologic parameters was also tested. Methods and Materials: The pathologic materials of 40 cervical uteri squamous cell carcinoma patients were examined and immunohistochemically stained to determine the tumor angiogenesis (tumor microvascular score), using factor VIII-related antigen, and their tumor apoptotic index (AI), using the TdT-mediated dUTP nick end-labeling (TUNEL) method. Three patients were Stage I, 18 were Stage II, 15 were Stage III, and 4 were Stage IV (FIGO classification). All patients were treated with radical radiotherapy and all had follow-up for more than 2 years. Results: The mean AI was 15.1 ± 12.8, with a median of 8.3. The mean tumor microvascular score was 3 9.7 ± 14.4, with a median of 3 8. The patients' age and tumor grade did not seem to significantly affect the prognosis. On the other hand, AI and angiogenesis (tumor microvascular score) were of high prognostic significance. The 3-year disease-free survival (DFS) rate for the patients having AI above the median was 78% (confidence interval [CI] 69-87%), compared to 32% (CI 22-42%) for those having AI below the median. The DFS was 18% (CI 9-27%) for patients having an angiogenesis score above the median, while it was 86% (CI 78-94%) for those patients having a score below the median. Conclusion: Determination of both tumor microvascular score and AI can identify patients with the best prognosis of 100% DFS (with low angiogenesis score and high AI). Women with a high score and low AI had the worst prognosis (DFS = 3%, CI 1-5%). Moreover, high AI can compensate partially for the aggressive behavior of tumors showing a high rate of angiogenesis.

the paper presents a rare case of metachronous gastric metastasis of uterine cervix cancer, clinically manifested through severe pyloric stenosis. 49-year-old patient, operated on in January 2009, with uterine cervix cancer (Squamous cell carcinoma T2bN1M0), is hospitalized in August 2011 with pyloric stenosis: epigastric pains, abundant, stasis, late postprandial emesis, significant weight loss, stomach form visible upon abdomen inspection. Endoscopy: antral stenosis with intact gastric mucosa, and CT-scan: circumferential intramural gastric tumor, stomach dilated in the upper part, lack of cleavage between the tumor and the liver bed of the gall bladder. CEA increased to 13,78 (below 5), CA 19-9 slightly increased 29.9 (below 27). The case is considered as a second neoplasia and a D2 subtotal gastrectomy was performed, with 1 positive ganglion out of 27 on block with atypical hepatectomy of segments 4-5 for liver invasion, the final mounting being Y Roux. The histopathological examination shows a gastric metastasis of squamous carcinoma, of uterine cervix origin, the invaded perigastric ganglion having the same aspect of uterine cervix carcinoma. The post-surgery evolution was favorable, under chemo radiotherapy the patient being alive without relapse at 9 months post-surgery. In the literature there are 2 more cases of gastric metastasis of uterine cervix carcinoma, and 4 of uterine carcinoma without topographic indication, but without the histological documentation of the tumor filiation, without data related to resecability or follow-up, the case at hand being, from this perspective, the first documented resectable metachronous gastric metastasis from a cervix uteri carcinoma.

Full Text Available Human papillomavirus (HPV that is a main cause of cancer of the cervix uteri (CCU has immunogenic properties, i.e. an abilityto activate antiviral immunity responses as adaptive HPV-specific and innate ones. For this reason, despite multiple mechanisms generated by HPV to avoid immunity responses, the human body can eliminate the infection in most cases. At the same time, CCU results from the combined influence of many factors of different nature, among which the factors that impair the normal course of an immune response are of vital importance.This review describes the major factors and mechanisms, which promote the establishment of persistent HPV infection and the progression of dysplasia to cancer, on the one hand, and allow the tumor cells in CCU to restrict the body’s immune reactions, on the other Immune disorders induced by the virus and/or tumor cells are considered at both local and systemic levels. Particular emphasis is placed on the molecular mechanisms that can change the population composition and functional activity of leukocytes and the cytokine profile of cells and can form the tumor suppressor microenvironment.

Histological evaluation was made on regional changes in 60 cases of carcinoma of the cervix uteri following Linac therapy which was employed prior to any other therapy. Correlation between this result and the effect of irradiation on the primary lesion was evaluated. Changes in carcinomatous cells following Linac irradiation were remarkably found in swelling, vacuolation hyalinization and decrease of nuclear division of the cytoplasm, and in swelling, vacuolation, concentration, and clasmatosis of nuclei, and also in swelling of nucleus. Changes in the interstice were hyperplasia of the surrounding connective tissues which became remarkable as a dose of the irradiation increased. However, the changes in the interstice seemed to appear a little late after the changes in the carcinomatous cells occurred. The density of blood-vessel distribution remained high until the irradiation of 3000r, and it became lower following the irradiation of 3000r or more. Thickening of the blood-vessel wall and obstruction of the blood-vessel cavity were marked following the irradiation of 3000r. Infiltration of the lymphoid cells was most advanced following the irradiation of 3000r. When the effectiveness of irradiation and histological changes were compared, there was a highly significant difference (p<0.01) in swelling of nuclei between remarkably effective cases and ineffective cases following the irradiation of 1000r or 2000r. There were significant differences (p<0.05) in swelling of the cytoplasm following the irradiation of 1000r or 2000r, clasmatosis of the nuclei following the irradiation of 3000r, the density of blood-vessel distribution before the therapy and following the irradiation of 2000r, and infiltration of lymphoid cells following the irradiation of 1000 or 3000r between two.

To compare the operative data and early postoperative outcomes of total laparoscopic hysterectomy (TLH), laparoscopically assisted vaginal hysterectomy (LAVH) and vaginal hysterectomy (VH). One hundred and eight women requiring hysterectomy for enlarged myomatous uterus were randomly allocated into three treatment arms: TLH (n = 36); LAVH (n = 36); VH (n = 36). Randomization procedure was based on a computer-generated list. The primary outcome was the discharge time comparison. The secondary outcomes were operating time, blood loss, paralytic ileus time, intraoperative complications, postoperative pain, and early postoperative complications. The mean discharge time was shorter after VH than after LAVH and TLH (P = 0.001). Operating time significantly influenced the discharge time, considered as a dependent variable in general linear model analysis (P = 0.006). In contrast, blood loss did not influence the discharge time (P = 0.55).The mean operating time was significantly shorter in VH than in TLH and LAVH groups (P = 0.000).The intraoperative blood loss was greater during LAVH than during TLH and VH (P = 0.000).Paralytic ileus time was shorter after VH than after TLH and LAVH (P = 0.000). No intraoperative complications or conversion to laparotomy occurred. VH was the faster operative technique with smaller blood loss and shorter discharge time compared with the others two techniques. So, VH should be considered the preferred approach in patients with enlarged myomatous uteri. When VH is not feasible or salpingo-oophorectomy is required, LAVH or TLH should be considered as valid alternatives. It is necessary to continue prospective comparative studies between the various surgical options to identify the best approach for hysterectomy in each single woman.

This drug containing chlorinated berberine and Gennoshoko extract was administered to cases which suffered from diarrhea during external irradiation, and its effect on them were observed. Out of 35 cases of cancer of the cervix uteri from stage I to III, 20 cases in which watery diarrhea was induced over three times a day by external irradiation were given 12 tablets per a day in four divided doses for 7 days. In external irradiation a total of 3000 rads was irradiated in 200 rads per a day (1000 rads per a week) by the whole pelvic irradiation, and after that, irradiation was performed up to 6000 rads by shielding the center. Diarrhea was observed in 20 of 35 cases during external irradiation (57.1%). Diarrhea was recognized in 4 cases in the range from 1000 to 2000 rads (20%), in 13 cases in the range from 2000 to 3000 rads (65%), and 3 cases irradiated by shielding the center (15%). Response to this drug was effective within 3 days after the administration in 9 cases (45%), a little effective in 7 cases (35%), and ineffective in 4 cases (20%). There was a past history of hypertension in cases whose response was ineffective. In the clinical examination after the administration of this drug, abnormalities in kidney and liver functions were not recognized. From the above-mentioned results, it was suggested that this drug was effective on diarrhea which occurred during external irradiation. (Kanao, N.)

Although flow cytometry (FCM) is used to evaluate cell surface markers of various leucocyte populations quantitatively, little is known about the usefulness of FCM in lymphoproliferative disorders of the ocular adnexa. The aim of this study was to disclose results of FCM, which were compared among IgG4-related ophthalmic disease (IgG4-ROD), idiopathic orbital inflammation (IOI), and extranodal marginal zone B-cell lymphoma (EMZL). This is a retrospective observational study. Sixty-nine tumors comprising of 16 IgG4-ROD, 24 IOI, and 29 EMZL were enrolled in the study. All tumors, surgically excised, were diagnosed based on histopathology, immunoglobulin (Ig) heavy chain gene rearrangement, and FCM. In FCM, the percentage of T-cell markers (CD2, CD3, CD4, CD5, CD7, CD8), B-cell markers (CD10, CD19, CD20, CD23), NK cell marker (CD56) and cell surface kappa/lambda was searched based on medical records. Ig light chain restriction was evaluated from results in kappa/lambda deviation by FCM. The percentage of CD2, CD3, CD4, CD7, and CD10 was significantly higher in IgG4-ROD/IOI than EMZL (pIgG4-ROD/IOI (pIgG4-ROD and IOI.

This medicine was authorized by the National Drug Agency (ANM, Bucureşti) in 2001. To evaluate the effectiveness and the tolerance to Cervugid-ovules, a preparation that combines the polyvalent local antiinflammatory action of chloramphenicol, metronidazole and nystatin with the effect of hydrocortisone acetate, an unspecific anti-inflammatory agent; they all are embedded in a Lipex-403, semisynthetic fat. The evaluation of 500 patients ages between 15 and 85 years with genital infections, registered in the files of "Cl. II Obst. and Gynecology" of the Cuza-Vodă Hospital from Iaşi has been studied. We studied the subjective manifestations (local discomfort and pelvic pains, local burning and dryness,vulvovaginal itching and dyspareunia) and objective manifestations (vaginal and cervical secretion, the cytotest performed and colored though the Papanicolaou method and reported in the Bethesda system). Healing of the subjective symptoms in 98%, healing of the leukorrhea--as a main objective symptom--in 95%; The Bethesda system cytotest was one of the inflammatory type in the most of the cases and there wew found in 85 cases: 6 ASCUS, 41 LSIL, and 37 HSIL. The use of Cervugid had a healing response in most of the cases when used in acute and chronic cervico-vaginal inflammatory processes. Cervugid may be considered as an important agent in the treatment of the precancerous affections af the cervix uteri on the following reasons: zhe cure of the infections caused by chlamydia, involved in the etiology of cervical neoplasms, the cure of the HPV infection under episome form, classified in the Bethesda system within the ASCUS, AGUS or LSIL classes. When the cytotest was in the HSIL class, a conization in the LLETZ method was performed. Cervugid is conceived for those three main categories of pathogenic factors related to the etiology of cervico-vaginitis: microbia germs, protozoa and mycosis. In addition, it is active on chlamydia and mycoplasms, always sensitive to

Data relating to 244 patients with carcinoma of the cervix uteri treated by intensive radiotherapy are given. Radiation injury of bone was diagnosed in 12 cases (4.9 +/- 1.4 percent). After x-ray therapy alone they were found in five of 59 patients treated (8.5 +/- 3.6 percent), and after γ-ray therapy in one of 171 cases (0.6 +/- 0.6 percent). The minimal focal dose of x-ray therapy causing radiation injury to bone was 5,000 rads. With an increase in dose, the frequency of injuries also increased. Radiation injury was found after γ-ray therapy with an absorbed dose of 7,000 rads. The radiological features of radiation injury of bones after irradiation of malignant tumors of the pelvis are increasing osteoporosis and the appearance of foci of sclerosis and osteolysis. Necrotic areas of various sizes may be formed. A fracture of the neck of the femur may be prevented in some cases by taking precautionary measures. Healing of an injured part depends on the size of the dose given. Large doses completely suppressed the reparative powers of the bone. Unlike changes that are traumatic in nature, radiation fractures of the pelvic bones and the proximal part of the femur have a mild clinical course; sometimes the patients continue to use the lower limb, simply complaining of pain that may vary in severity. Metastasization of tumors of the uterus to the pelvic bones is possible but infrequent. Metastases are usually associated with increasing pain

To compare the performance of human papillomavirus DNA tests (samples collected by a healthcare professional and self-collected) and liquid-based cytology with conventional cytology in the detection of cervix uteri cancer and its precursor lesions. A cross-sectional study was carried out in 1777 women living in poor communities in Rio de Janeiro State, Brazil. Eligibility criteria included ages 25-59 years and not having had a Papanicolau test within at least 3 years prior to the study. Cytology (conventional or liquid-based) and human papillomavirus DNA (collected by a healthcare professional or self-collected) tests were performed using samples collected in a single visit. Women with abnormalities in at least one test and a systematic sample of 70 women with negative test results were referred to a colposcopic examination. Test readings were double-masked, and the outcome of interest was high-grade squamous intraepithelial lesion or worse. The pathology report was used as the gold standard. The prevalence of high-grade squamous intraepithelial lesion or worse was 2.0%. Human papillomavirus DNA test collected by a health professional alone or combined with conventional cytology had the highest sensitivity (91.4 and 97.1%, respectively). The highest specificity was found for conventional cytology (91.6%) and for a human papillomavirus DNA test collected by a healthcare professional (90.2%). On the basis of only test performance, the use of human papillomavirus DNA tests, alone or combined with cytology, would seem to be recommended. Its population-wide implementation, however, is conditional on a cost-effectiveness analysis.

A patient dose distribution was calculated by a 3D multi‐group SN particle transport code for intracavitary brachytherapy of the cervix uteri and compared to previously published Monte Carlo results. A Cs‐137 LDR intracavitary brachytherapy CT data set was chosen from our clinical database. MCNPX version 2.5.c, was used to calculate the dose distribution. A 3D multi‐group SN particle transport code, Attila version 6.1.1 was used to simulate the same patient. Each patient applicator was built in SolidWorks, a mechanical design package, and then assembled with a coordinate transformation and rotation for the patient. The SolidWorks exported applicator geometry was imported into Attila for calculation. Dose matrices were overlaid on the patient CT data set. Dose volume histograms and point doses were compared. The MCNPX calculation required 14.8 hours, whereas the Attila calculation required 22.2 minutes on a 1.8 GHz AMD Opteron CPU. Agreement between Attila and MCNPX dose calculations at the ICRU 38 points was within ±3%. Calculated doses to the 2 cc and 5 cc volumes of highest dose differed by not more than ±1.1% between the two codes. Dose and DVH overlays agreed well qualitatively. Attila can calculate dose accurately and efficiently for this Cs‐137 CT‐based patient geometry. Our data showed that a three‐group cross‐section set is adequate for Cs‐137 computations. Future work is aimed at implementing an optimized version of Attila for radiotherapy calculations. PACS number: 87.53.Jw

to investigate the expression of the membrane-bound matrix metalloproteinase MT1-MMP (MMP-14), its tissue inhibitor TIMP-2, and the proMMP-14 activator furin in the corpus uteri from the vaginal wall to the bottom of the uterine cavity in squamous cell carcinoma of the cervix (SCCC). Hysterectomy material was examined in patients with SCCC. Reverse transcriptase polymerase chain reaction (RT-PCR), immunohistochemistry (IHC), and enzyme assays were used. In SCCC, higher levels of MMP-14 expression were established in tumor cells, as evidenced by IHC (+3) and RT-PCR. IHC showed that the expression of MMP-14 was absent or insignificant in the normal uterine endometrial and myometrial tissues. However, that of MMP-14 mRNA was also found in the normal tissues to the bottom of the uterine cavity. Furin activity in the tumor was much higher than that in normal tissues. IHC indicated that TIMP-2 expression was low or absent in both the tumor and normal tissues. The expression of TIMP-2 mRNA was sufficiently obvious in both the tumor and normal tissues to the bottom of the uterine cavity. In SCCC, MMP-14 expression was substantially increased in tumors. The expression of MMP-14 and regulators of its activity is aimed at enhancing the tumor destructive (invasive) potential in the pericellular space and can occur (be induced) in the morphologically normal uterine tissue apparently with involvement of signaling through the epithelial-mesenchymal interaction. Data are important for understanding the role of MMP-14 in the development of a multistage process of carcinogenesis and may have prognostic value and an impact on therapeutic strategy for the patient.

To compare the effectiveness and acceptability of LNG-IUD with oral progesterone (norethisterone acetate; NETA) in achieving a reduction in volume of the myomas, hemoglobin levels, satisfaction of the women. This study includes randomized 30 women treated by LNG-IUD and randomized 30 women treated by oral norethisterone (NETA). All these participants in the study have received medical treatment and had been registered as patients in Istanbul Medeniyet University Göztepe Education and Research Hospital. Leiomyoma volumes and hemoglobin levels have been determined. In the third and sixth months, these measurements have been done again. We examined the adverse effects and the treatment continuity. For the statistical analysis of the findings NCSS [Number Cruncher Statistical System] 2007 & PASS 2008 program; student t, Mann Whitney U, Paired Samples t, Wilcoxon Signed Ranks, Ki-Kare, Fisher's Exact Ki-Kare tests have been used. After six months treatment, the reduction of bleeding determined by Visual Bleeding Score (VBS) in LNG-IUD group is 80% and in oral norethisteron group is 56%; in both groups leiomyoma volumes and hemoglobin levels were significantly high. LNG-IUD is a good alternative treatment to the oral progesterone in long term minimizing the hysterectomy for myoma uteri because of the good patient tolerance and easy usage.

Two cases of puerperal thrombophlebitis of the ovarian veins are described and the literature is reviewed. By means of computer tomography, it has become possible for the first time to make the diagnosis of this little-known and frequently missed condition by a non-invasive method. The patient is spared complicated angiographic procedures and possibly also surgery. The typical CT findings consist of: a) a thickened adnexa, b) a circular lesion extending from the adnexa to the hilum of the kidney, c) an obstructed ureter and c) an enlarged uterus. (orig.) [de

Full Text Available Today, the common term metabolic syndrome encompasses visceral (abdominal obesity, glucose intolerance, type 2 diabetes mellitus (DM, hypertension, and dyslipidemia. In Europe, the rate of obesity mong the women ranges from 6 to 36 %. In the USA, 65 % of the adult population is overweight and 30 % is obese. High estrogen production in adipose tissue in patients with obesity has been established to increase the risk of cancer of the corpus uteri (CCU by 4 times as compared to that in normal weight female patients. Furthermore, obese patients are at increased risk for DM that is also a risk factor for CCU. A rise in the number of obese patients leads to the population redistribution of gynecological cancer. The increasing number of patients with gynecological cancer is overweight. This patient group has an increased risk from surgery and anesthesia, a higher incidence of postoperative complications, and delayed recovery. Laparotomy increases the duration of hospital stay and the rate of wound complications. The frequency of urologic injuries in obese patients varies between 2 and 4 %. In this patient category, the rate of damage to the large vessels or bowels has also statistically significant differences. The literature highlights a number of complications specific to patients with obesity: trocar damage to anterior abdominal wall vessels, particularly to the inferior epigastric artery, urinary bladder, as well as trocar site hernia. The authors describe their experience in treating CCU patients with metabolic syndrome at the Department of Surgery for Female Reproductive System Tumors, N. N. Blokhin Russian Cancer Research Center. They demonstrate that laparoscopic extirpation of the uterus and its appendages can be performed in patients with third-degree obesity (weighing 174 kg in Stage I CCU. It should be noted that this weight was previously regarded as an absolute contraindication to surgical treatment. Today, the active

The effect of performing corrections on reported uterine cancer mortality data in the city of São Paulo

Full Text Available Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003, and area-level distribution based on three strategies: i using uncorrected death certificate information; ii correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively and corpus uteri (34.4 and 55.2% cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

1983-01-01

The study is concerned with immunologic status (cell-mediated and humoral immunity) as a factor influencing the choice of scheme of treatment for carcinoma of cervix uteri. The indexes of immunocompetence should be taken into account in planning the differential treatment of precancer and early forms of carcinoma of cervix uteri. Radiation treatment exerts an immunosuppressive effect. However, immunologic indexes are not affected considerably by laser destruction or surgery. Cryodestruction has a beneficial effect on cell-mediated immunity. Considering these effects as well as the long-term results of different orocedures of treatment, laser coagulation, cryogenic destruction or diathermoconization should be recommended for management of carcinoma in situ of cervix uteri, and extensive extirpation of the uterus, unattended by radiation, for Tla

Uteri are among the most common surgical pathology specimens. Assessment of the endometrium is often difficult because of pronounced tissue autolysis. This study describes a simple method to prevent endometrial autolysis and aid in interpretation of the endometrium. Sixty uteri were injected with formalin using a needle and syringe directed alongside a probe, which was inserted through the external cervical os into the endometrial cavity. Injection was performed on the same day as removal of the uterus. As controls, 60 uteri that were not injected with formalin were examined. The degree of endometrial autolysis was assessed on a four point scale (0-3), with a score of 0 representing no or minimal autolysis and a score of 3 representing extensive autolysis, such that histological interpretation of the endometrium was impossible. In the injected group, the number of cases with scores of 0, 1, 2, and 3 was 42, 13, four, and one, respectively. The corresponding values for the control group were 17, 23, eight, and 12, respectively. This was highly significant (p autolysis in uteri injected with formalin. The use of this simple procedure should be encouraged in hysterectomy specimens.

to carry out a quantitative analysis of diffusion-weighted magnetic resonance images (DWI) in cancer of the cervix uteri (CCU) and to estimate the possibility of using pretreatment measured diffusion coefficient (MDC) to predict chemoradiation therapy (CRT). The investigation prospectively enrolled 46 women with morphologically verified Stages IB-IVB CCU. All the women underwent diffusion-weighted magnetic resonance imaging of pelvic organs before and after treatment. A semiautomatic method was used to determine tumor signal intensity (SI) on DWI at b 1000 s/mm2 (SI b1000) and tumor MDC. The reproducibility of MDC measurements was assessed in 16 randomly selected women. The investigators compared the pretreatment quantitative DWI measures in complete and incomplete regression (CR and IR) groups and the presence and absence of tumor progression during a follow-up. An association of MDC with progression-free and overall survivals (PFS and OS) was determined in the patients. A semiautomatic tumor segmentation framework could determine the pretreatment quantitative DMI measures with minimal time spent and high reproducibility. The mean tumor MDC was 0.82 +/- 0.14 x 10(-3) mm2/s. CR and IR were established in 28 and 18 women, respectively. The MDC < or = 0.83 x 10(-3) mm2/s predicted CR with a sensitivity of 64.3% and a specificity of 77.8% (p=0.007). The median follow-up was 47 months (range, 3-82 months). With the MDC < or = 0.86 x 10(-3) mm2/s, 5-year PFS was 74.1% versus 42.1% with a higher MDC (p=0.023) and 5-year OS was 70.4 and 40.6%, respectively (p=0.021). The survival difference was insignificant in relation to the degree of tumor regression. The pretreatment IS at b1000 was of no prognostic value. The pretreatment tumor MDC may serve as a biomarker for predicting the efficiency of CRT for CCU.

common type (55%) of primary ocular adnexal lymphoma, but comprised only 19% of secondary tumors (p=0.002); follicle center lymphoma was second in frequency (22%) in primary cases but the most common lymphoma to secondarily involve the orbit (38%) (p=0.05). MALT lymphomas had a significantly higher frequency of localized disease at presentation (87%) than follicle center lymphoma (53%) (p=0.03). Moderate radiation doses resulted in 100% actuarial local control at 6 years and a 77% probability of remaining distant relapse free at 6 years in patients with localized disease. Patients with MALT lymphomas may have a lower relapse rate than those with follicle center lymphomas. Our data suggest that MALT lymphoma of the ocular adnexae is a localized tumor that may be curable with moderate doses of radiation therapy

Incidence of second primary cancers was evaluated in 7,127 women with invasive cancer of the cervix uteri, diagnosed between 1935 and 1978, and followed up to 38 years (average, 8.9 yr) in Connecticut. Among 5,997 women treated with radiation, 449 developed second primary cancers compared with 313 expected (relative risk . 1.4) on the basis of rates from the Connecticut Tumor Registry. Excess incidence was noticeable 15 years or more after radiotherapy and attributed mostly to cancers of sites in or near the radiation field, especially the bladder, kidneys, rectum, corpus uteri, and ovaries. No excess was found for these sites among the 1,130 nonirradiated women. The ratio of observed to expected cancers for these sites did not vary appreciably by age at irradiation. The data suggested that high-dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but, apparently, not leukemia, Hodgkin's disease, breast cancer, or colon cancer

A variação do nível hidrométrico dos rios influenciou na concentração de oxigênio dissolvido e pH. Essa variação foi um dos fatores determinantes na flutuação mensal da densidade das larvas. A diferença entre as lagoas, mostrada na análise DCA, deveu-se, principalmente, à variação da densidade de Odonata.Samples of aquatic macrophytes were collected on Guaraná (Eichhornia azurea and Patos (E. crassipes and E. azurea Lakes from March 1992 to February 1993. On Guaraná Lake the highest density and diversity were registered during the high water phase with dominance of Telebasis and Acanthagrion, while on Patos Lake, highest density and diversity were observed during the low water phase. The dominant taxa on Patos Lake were Telebasis, Acanthagrion, Neoneura (?,Coryphaeschna adnexa, Miathyria, Diastatops intensa and Erythemis. DCA and ANOVA differentiated Patos Lake mainly, because of the high abundance of C. adnexa, Miathyria, D. intensa and Erythemis which may be due to morphology of E. crassipes that shelters larger number of invertebrates. Water level variation of rivers influenced concentration of dissolved oxygen and pH. This variation was

Ophthalmomyiasis externa by Musca domestica in a case of orbital metastasis

Full Text Available Infestation of the living tissues of the eye, ocular adnexae or orbit by larvae of flies of the order Diptera is known as ophthalmomyiasis. Ophthalmomyiasis externa is a limited superficial infestation of external ocular structures such as conjunctiva and adnexae. A case of follicular carcinoma thyroid with orbital metastasis presenting as ophthalmomyiasis externa is reported. The patient presented with foul smelling ulcers of the medial and lateral orbital walls of the right eye extending into the lids and nose, teeming with maggots. Computerized Tomography (CT showed widespread bone destruction with extension into surrounding sinuses. Over 200 maggots were manually removed after immobilisation with turpentine oil instillation. Entomological examination showed it to be a case of accidental myiasis caused by the common housefly Musca domestica. The patient was managed conservatively and the ulcer cavities filled up with healthy granulation tissue. This case is presented on account of its rarity.

Type II endometrial carcinomas (ECs) are estrogen independent, poorly differentiated tumors that behave in an aggressive manner. As TP53 mutation and CDH1 inactivation occur in 80% of human endometrial type II carcinomas, we hypothesized that mouse uteri lacking both Trp53 and Cdh1 would exhibit a phenotype indicative of neoplastic transformation. Mice with conditional ablation of Cdh1 and Trp53 (Cdh1(d/d)Trp53(d/d)) clearly demonstrate architectural features characteristic of type II ECs, including focal areas of papillary differentiation, protruding cytoplasm into the lumen (hobnailing) and severe nuclear atypia at 6 months of age. Further, Cdh1(d/d)Trp53(d/d) tumors in 12-month-old mice were highly aggressive, and metastasized to nearby and distant organs within the peritoneal cavity, such as abdominal lymph nodes, mesentery and peri-intestinal adipose tissues, demonstrating that tumorigenesis in this model proceeds through the universally recognized morphological intermediates associated with type II endometrial neoplasia. We also observed abundant cell proliferation and complex angiogenesis in the uteri of Cdh1(d/d)Trp53(d/d) mice. Our microarray analysis found that most of the genes differentially regulated in the uteri of Cdh1(d/d)Trp53(d/d) mice were involved in inflammatory responses. CD163 and Arg1, markers for tumor-associated macrophages, were also detected and increased in the uteri of Cdh1(d/d)Trp53(d/d) mice, suggesting that an inflammatory tumor microenvironment with immune cell recruitment is augmenting tumor development in Cdh1(d/d)Trp53(d/d) uteri. Further, inflammatory mediators secreted from CDH1-negative, TP53 mutant endometrial cancer cells induced normal macrophages to express inflammatory-related genes through activation of nuclear factor-κB signaling. These results indicate that absence of CDH1 and TP53 in endometrial cells initiates chronic inflammation, promotes tumor microenvironment development following the recruitment of macrophages

Oestrogen-induced uterine fluid sodium (Na(+)) and bicarbonate (HCO3(-)) secretion may involve SLC4A4. We hypothesized that uterine SLC4A4 expression changes under different sex-steroid influence, therefore may account for the fluctuation in uterine fluid Na(+) and HCO3(-) content throughout the oestrous cycle. The aim of this study is to investigate the differential effects of sex-steroids and oestrous cycle phases on uterine SLC4A4 expression. Adult female WKY rats were ovariectomised and treated with different doses of 17β-oestradiol (E2) (0.2, 2, 20 and 50 μg/ml/day) or progesterone (P4) (4 mg/ml/day) for three consecutive days and 3 days treatment with 0.2 μg/ml/day E2 followed by another 3 days with P4 to mimic the hormonal changes in early pregnancy. Oestrous cycle phases in intact, non-ovariectomised rats were determined by vaginal smear. The animals were then sacrificed and uteri were removed for protein and mRNA expression analyses by Western blotting and Real Time PCR, respectively. SLC4A4 distribution was observed by immunohistochemistry. Treatment with increasing E2 doses resulted in a dose-dependent increase in SLC4A4 protein expression. High SLC4A4 protein and mRNA expression can be seen at estrus. SLC4A4 is distributed mainly at the apical as well as basolateral membranes of the luminal and glandular epithelia following E2 treatment and at Es. Meanwhile, SLC4A4 expression was reduced following P4 treatment and was low at diestrus. High SLC4A4 expression under estrogen dominance may contribute to the increase in uterine fluid Na(+) and HCO3(-) content, while its low expression under P4 dominance may result in vice versa.

ABSTRACT E-cadherin (CDH1) is a cell adhesion molecule that coordinates key morphogenetic processes regulating cell growth, cell proliferation, and apoptosis. Loss of CDH1 is a trademark of the cellular event epithelial to mesenchymal transition, which increases the metastatic potential of malignant cells. PTEN is a tumor-suppressor gene commonly mutated in many human cancers, including endometrial cancer. In the mouse uterus, ablation of Pten induces epithelial hyperplasia, leading to endometrial carcinomas. However, loss of Pten alone does not affect longevity until around 5 mo. Similarly, conditional ablation of Cdh1 alone does not predispose mice to cancer. In this study, we characterized the impact of dual Cdh1 and Pten ablation (Cdh1d/d Ptend/d) in the mouse uterus. We observed that Cdh1d/d Ptend/d mice died at Postnatal Days 15–19 with massive blood loss. Their uteri were abnormally structured with curly horns, disorganized epithelial structure, and increased cell proliferation. Co-immunostaining of KRT8 and ACTA2 showed invasion of epithelial cells into the myometrium. Further, the uteri of Cdh1d/d Ptend/d mice had prevalent vascularization in both the endometrium and myometrium. We also observed reduced expression of estrogen and progesterone receptors, loss of cell adherens, and tight junction molecules (CTNNB1 and claudin), as well as activation of AKT in the uteri of Cdh1d/d Ptend/d mice. However, complex hyperplasia was not found in the uteri of Cdh1d/d Ptend/d mice. Collectively, these findings suggest that ablation of Pten with Cdh1 in the uterus accelerates cellular invasiveness and angiogenesis and causes early death. PMID:23740945

2011-01-01

Full Text Available Of the approximately 80,000 new cases of all cancers detected every year in India, 10-15% are gynecological malignancies. As per population-based registries under the National Cancer Registry Program, the leading sites of cancer among women are the cervix uteri, breast, and oral cavity. About 50-60% of all cancers among women in India are mainly of the following four organs: cervix uteri, breast, corpus uteri, and ovaries. Over 70% of these women report for diagnostic and treatment services at an advanced stage of disease, resulting in poor survival and high mortality rates. Among all gynecological cancers, ovarian cancer is the deadliest one and, in 2/3 rd of the cases, is detected in an advanced stage. But, in India and in other developing countries, due to inadequate screening facilities for the preventable cancer cervix, this kills more women than any other cancer in females. Gynecology Oncologist as a sub-specialist has an immensely important role in curtailing the menace of gynecological malignancies by providing comprehensive preventive, curative, palliative and follow-up services, with the aim of assuring a good quality of life to women as a cornerstone of cancer management.

[Preventing complications due to dilatation by intracervical application of a prostaglandin-gel (author's transl)].

Mechanical injuries by dilatating the cervix uteri for artificial abortion may lead to intra- and postoperative complications; of these cervical insufficiency during subsequent pregnancy is of main importance. In order to prevent this complication 160 patients in the 8th to 18th week of pregnancy, who were going to have a legal abortion, were treated with a gel consisting of 3--5 mg Prostaglandin F2alpha which was applicated in the cervix uteri. In more than 90% of these cases a mechanical dilatation was not necessary afterwards. Generally the cervix uteri was softened and dilatated to Hegar 12. 32% of the patients had a spontaneous abortion. Therefore only a curettage without a dilatation had to be performed. Complications due to the application of the gel did not occur. The combined application of the gel with the extraamnial instillation of Prostaglandin for artificial abortion during the second trimenon reduced by half the period of indwelling of the intrauterine foley-catheter and therewith the risk of infection as well as the period of labour pains. Further possible ways of applicating the Prostaglandin gel in gynecology and obstetrics concern missed abortion, intrauterine death, and cervical dystocia during delivery.

Embryonic diapause is a reproductive strategy widespread in the animal kingdom. This phenomenon is defined by a temporary arrest in blastocyst growth and metabolic activity within a quiescent uterus without implantation until the environmental and maternal milieu become favorable for pregnancy to progress. We found that uterine Msx expression persists during diapause across species; their inactivation in the mouse uterus results in termination of diapause with the development of implantation-like responses (“pseudoimplantation”) that ultimately succumbed to resorption. To understand the cause of this failure, we compared proteome profiles between floxed and Msx-deleted uteri. In deleted uteri, several functional networks, including transcription/translation, ubiquitin-proteasome, inflammation, and endoplasmic reticulum stress, were dysregulated. Computational modeling predicted intersection of these pathways on an enhanced inflammatory signature. Further studies showed that this signature was reflected in increased phosphorylated IκB levels and nuclear NFκB in deleted uteri. This was associated with enhanced proteasome activity and endoplasmic reticulum stress. Interestingly, treatment with anti-inflammatory glucocorticoid (dexamethasone) reduced the inflammatory signature with improvement of the diapause phenotype. These findings highlight an unexpected role of uterine Msx in limiting aberrant inflammatory responses to maintain embryonic diapause. PMID:25931120

Persistent infection of human papillomavirus is known to cause cervical intraepithelial neoplasia or cancer in the cervix uteri and other HPV-associated cancers in different localization. Based on epidemiological and biological data, principally the high risk HPV is responsible for development of cervical these cancers. However, we have no information about the frequently distribution of different HPV types and what is the correlation between the HPV types and cytological diagnosis in cervical intraepithelial neoplasia (CIN). In this paper, we are going to present new data involving incidence and mortality of HPV-associated cancers during the period of 2009-2015 in Hungary. We are also going to investigate the correlation of cervical cytological diagnosis and HPV typing, and the preventive effect of HPV vaccination. The epidemiological data spring from the National Cancer Registry. HPV typing was performed by Linear Array HPV Genotyping Test. Simultaneous cytological diagnosis and HPV typing was carried out on 2048 cytological samples collected in period of 2009-2016. According to the epidemiologic data, the most frequently occurring HPV-associated cancer is the laryngeal carcinoma in man, and the cervical cancer in woman in Hungary. During the 2009-2015 time intervals, the frequency distribution of head and neck cancers was not changed in man, but the incidence of tongue root squamous cell carcinomas was gradually increasing in woman. We have defined the clinical significance of single and simultaneously multiple HPV infection and have investigated the correlation of the HPV frequency distribution and cytological diagnosis in CIN. It was found that in the cytological negativity of probably/possibly carcinogen pHR-HPV group classified by IACR was much more frequent as in HR-HPV group (56% versus 47%). The presence of simultaneous multiplex HPV infection betokens an increased cancer risk. According to the international publications, the ratio of HPV16 just twice as

What would be a potential impact of implementing the new ESHRE/European Society of Gynaecological Endoscopy (ESGE) female genital anomalies classification system on the management of women with previous diagnosis of arcuate uteri based on the modified American Society for Reproductive Medicine (ASRM) criteria? A significant number of women with previous diagnosis of arcuate uteri are reclassified as having partial septate uteri according to the new ESHRE/ESGE classification system which may increase the number of remedial surgical procedures. The ESHRE/ESGE classification system has defined measurement techniques, reference points and specific cut-offs to facilitate the differentiation between normal and septate uteri. These criteria have been arbitrarily defined and they rely on the measurement of uterine wall thickness and depth of distortion of uterine fundus. This was a retrospective cohort study. We searched our ultrasound clinic database from January 2011 to December 2014 to identify all women diagnosed with arcuate uterus on three-dimensional ultrasound according to the modified ASRM criteria. For each woman, the ultrasound images were stored in our clinical database and they were re-examined according to ESHRE/ESGE specifications. The presence and location of all acquired uterine anomalies, such as fibroids or adenomyosis was noted. We applied the two diagnostic approaches as specified by the ESHRE/ESGE classification: the main option (MO) and the alternative option (AO). We used the Kappa statistic to quantify the agreement between the two approaches. We also compared the number of previous miscarriages in women with normal and partial septate uteri according to the ESHRE/ESGE classification. Non-parametric Mann-Whitney and Kruskal-Wallis tests were used for the analyses and receiver-operating characteristic curves were constructed to assess the predictive values of the calculated uterine distortion indices for the detection of women at risk of suffering

Full Text Available The trigeminal nerve carries the sensory innervation of the eye and adnexa in three divisions: ophthalmic, maxillary, and mandibular. The sensory fibres of the eye and adnexa are found in the ophthalmic division – with the exception of a portion of the sensory input from the lower lid, which is carried by the maxillary division. Blocking the sensory fibres provides anaesthesia so that no pain is felt.The motor supply of the extraocular muscles and levator palpebrae superioris is carried by the oculomotor (III, trochlear (IV, and abducens (VI nerves. Paralysing these muscles by blocking their motor supply provides akinesia so that the eye does not move during surgery.The motor supply of the orbicularis oculi, which is responsible for the gentle and forcible closure of the eye, is carried by the facial nerve (VII. Blocking these fibres will provide better surgical exposure. It also reduces the risk of forcing out the ocular contents if the patient tries to close his eyelids forcibly after the surgeon opens the globe.

Results of 131 I-hippuran (0.74 MBq) nephrography and 99m Tc DMCA (55.6 MBq) scintigraphy of the kidneys in 204 women from 21 to 75 years of age are analyzed. All patients were examined before and after treatment (surgical, radiation, hormonal). It was found that combined radiotherapy of patients with cervix uteri cancer and surgical treatment of patients with corpus uteri cancer resulted in aggravation of the secretory and excretory renal disorders, as compared to the pre-treatment state. It was not until after the second year of treatment that normal renal function was reestablished. Radionuclide methods furnish the opportunity both for early detection of renal function disorders and for their dynamic control and treatment. 1 tab., 4 refs

Estrogen, progesterone, and genistein differentially regulate levels of expression of α-, β-, and γ-epithelial sodium channel (ENaC) and α-sodium potassium pump (Na⁺/K⁺-ATPase) in the uteri of sex steroid-deficient rats.

Estrogen, progesterone, and genistein could induce changes in uterine fluid volume and Na(+) concentration. Progesterone upregulates expression of epithelial sodium channel (ENaC) and Na(+)/K(+)-ATPase which contributed toward these changes. However, effects of estrogen and genistein were unknown. This study therefore investigated changes in expression of these proteins in the uterus under estrogen, progesterone, and genistein influences to further understand mechanisms underlying sex steroids and phytoestrogen effects on uterine fluid Na(+) regulation. In this study, uteri of ovariectomized female rats receiving 7-day treatment with genistein (25, 50, and 100 mg/kg/day), estrogen (0.8 × 10(-4) mg/kg/day), or progesterone (4 mg/kg/day) were harvested, and expression levels of α-, β-, and γ-ENaC proteins and messenger RNAs (mRNAs) and α-Na(+)/K(+)-ATPase protein were determined by Western blotting (proteins) and real-time polymerase chain reaction (mRNA). Meanwhile, distribution of α-, β-, and γ-ENaC and α-Na(+)/K(+)-ATPase proteins in the uterus was identified by immunohistochemistry. Our findings indicated that expression of α-, β-, and γ-ENaC proteins and mRNAs and α-Na(+)/K(+)-ATPase protein were enhanced under progesterone influence. Lower expressions were noted under estrogen and genistein influences compared to progesterone. Under estrogen, progesterone, and genistein influences, α- and β-ENaC were distributed at apical membrane and γ-ENaC was distributed at apical and basolateral membranes of uterine luminal epithelia. Under progesterone influence, α-Na(+)/K(+)-ATPase was highly expressed at basolateral membrane. In conclusion, high expression of α-, β-, and γ-ENaC and α-Na(+)/K(+)-ATPase under progesterone influence would contribute toward increased uterine fluid Na(+) reabsorption, whereas lesser expression of these proteins under estrogen and genistein influences would contribute toward lower reabsorption of uterine fluid Na

Can we rely on cancer mortality data? Checking the validity of cervical cancer mortality data for Slovenia

International Nuclear Information System (INIS)

Primic Zakelj, M.; Pompe Kirn, V.; Skrlec, F.; Selb, J.

2001-01-01

Background. Valid inference on cervical cancer mortality is very difficult since - on the basis of death certificates - it is not always possible to distinguish between cervix, corpus and unspecified uterine cancer deaths. Our aim was to estimate the extent to which cervical cancer as the official cause of death reflects the true mortality from cervical cancer in Slovenia. Material and methods. The data on 2245 deaths from cervix, corpus uteri, and uterus-unspecified cancers for the period 1985-1999 were linked to the Cancer Registry of Slovenia database from the mortality database of Slovenia. Results. Officially, in the period 1985-1999, there were 878 cervical cancer deaths. The comparison of these causes of death with the cancer sites registered in the Cancer Registry revealed that they include only 87.7% patients with a previous diagnosis of cervical cancer. Of 650 corpus uteri cancer deaths, 17. 1 % of patients were registered to have cervical cancer, and of 717 unspecified uterine cancer deaths, 31.4% were registered. Taking into account the correctly identified cervical cancer cases among cervical cancer deaths and misclassified cervical cancer deaths as corpus uteri and unspecified uterine, the corrected number of deaths would be 1106. Conclusions. When evaluating the impact of cervical cancer mortality from national mortality rates, the stated underestimation should be taken into account. However, this does not hold for some other cancers. (author)

Basic studies on the human uterus by magnetic resonance imaging

1990-01-01

This study was designed to analyze characteristic features of the human uterus by using a 0.5 Tesla super-conducting magnet. Relative square ratios of the endometrium and the junctional zone to the uterine body were measured during menstrual cycle with a computed image analyser. Nine healthy volunteers aged 21 to 30 years underwent magnetic resonance imaging (MRI) in the proliferative, secretory, and menstrual phases. Relaxation times of the endometrium, junctional zone, and myometrium were determined. The relative ratio of the endometrium to the uterine body was 13.8% in the proliferative phase, 17.9% in the secretory phase, and 8.0% in the menstrual phase. The ratio of the junctional zone decreased from 26.6% in the proliferative phase to 23.4% in the secretory phase, and increased to 35.0% in the menstrual phase. Relaxation times of the endometrium and junctional zone were the shortest in the menstrual phase. For the myometrium, T 1 values showed the same tendency. T 2 values were the shortest in the proliferative phase. MRI was also performed in 39 patients with hydatidiform (one), myoma uteri (11), adenomyosis uteri (one), carcinoma of the uterine body (3), and carcinoma of the uterine cervix (23). Myoma nodule without degeneration appeared at low intensity, and had the shortest T 1 and T 2 values. Myoma uteri with degeneration had an increased intensity and larger T 1 and T 2 values. Adenomyosis uteri showed a diffuse low intensity with high intensity spots. Malignant lesions of both the uterine body and cervix showed a high intensity on T 2 -weighted image and similar T 1 and T 2 values. These T 1 and T 2 values were, however, shorter than tissue of unmarried normal women. MRI was considered useful for the observation of menstrual cyclic and quantitative change in the human physiologic uterus, as well as for the differentiation of malignant from benign uterine diseases.

Full Text Available Abstract Introduction Peripheral primitive neuroectodermal tumor of the cervix uteri is extremely rare. Between 1987 and 2010, there were only nine cases reported in the English literature, with considerably different management policies. Case presentation A 45-year-old Iranian woman presented to our facility with a primitive neuroectodermal tumor of the cervix uteri. Her clinical stage IB2 tumor was treated successfully with chemotherapy. Our patient underwent radical hysterectomy. There was no trace of the tumor after four years of follow-up. Conclusions According to current knowledge, primitive neuroectodermal tumors belong to the Ewing's sarcoma family, and the improvement of treatment outcome in our patient was due to dose-intensive neoadjuvant chemotherapy, surgery and consolidation chemotherapy in accordance with the protocol for bony Ewing's sarcoma.

A diabetic patient developed necrolytic migratory erythema with extensive angioplasia and high molecular weight glucagon-like polypeptide. There was no associated neoplasm such as glucagonoma. Lesions in the skin were studied by standard optical microscopy and by radioautography after incorporation of tritiated thymidine. Alterations in the skin begin as focal necrosis in the epidermis and in epithelial structures of adnexa, followed by marked angioplasia and a superficial and deep perivascular dermatitis

Simultaneous Bilateral Tubal Pregnancy After In Vitro Fertilization and Embryo Transfer

Directory of Open Access Journals (Sweden)

Sunduz Ozlem Altinkaya

2008-09-01

Conclusion: The diagnosis of ectopic or heterotopic pregnancy should always be considered in patients undergoing IVF-ET because of its increased incidence with this technique compared with natural conception. Although the incidence of bilateral tubal pregnancy is not high, sonographers and surgeons should examine both adnexa when diagnosing an ectopic pregnancy, especially in IVF-ET patients. Early diagnosis is essential for the prevention of significant maternal morbidity and mortality.

Lindeberg, Heli; Burchmore, Richard J S; Kennedy, Malcolm W

2017-03-01

Uterine secretory proteins protect the uterus and conceptuses against infection, facilitate implantation, control cellular damage resulting from implantation, and supply pre-implantation embryos with nutrients. Unlike in humans, the early conceptus of the European polecat ( Mustela putorius ; ferret) grows and develops free in the uterus until implanting at about 12 days after mating. We found that the proteins appearing in polecat uteri changed dramatically with time leading to implantation. Several of these proteins have also been found in pregnant uteri of other eutherian mammals. However, we found a combination of two increasingly abundant proteins that have not been recorded before in pre-placentation uteri. First, the broad-spectrum proteinase inhibitor α 2 -macroglobulin rose to dominate the protein profile by the time of implantation. Its functions may be to limit damage caused by the release of proteinases during implantation or infection, and to control other processes around sites of implantation. Second, lipocalin-1 (also known as tear lipocalin) also increased substantially in concentration. This protein has not previously been recorded as a uterine secretion in pregnancy in any species. If polecat lipocalin-1 has similar biological properties to that of humans, then it may have a combined function in antimicrobial protection and transporting or scavenging lipids. The changes in the uterine secretory protein repertoire of European polecats is therefore unusual, and may be representative of pre-placentation supportive uterine secretions in mustelids (otters, weasels, badgers, mink, wolverines) in general.

Growth and viability of Aedes albopictus cell line in vitro after cesium-137 gamma irradiation

International Nuclear Information System (INIS)

Blakely, E.A.

1975-01-01

The radiosensitivity of the cultured mosquito cell line Aedes albopictus (Skuse) was investigated. Population growth was followed by total cell counts and by viable cell counts on aliquots of cultures exposed to various doses of gamma radiation during exponential growth. Viable cell determinations were based on the cellular exclusion of the dye, alcian blue, in a procedure adapted to the insect cells in culture. Viability determinations in the irradiated exponential cultures indicated that initially there was some increase in the gestation, suggesting that gonadal steroids may have unusual effects on uterine physiology and biochemistry in this species. Consequently, studies were undertaken to elucidate some of the basic responses of hamster uteri to estradiol benzoate and progesterone under conditions of protein malnutrition, actinomycin D administration and corticosterone injection. Furthermore, the effects of gonadal steroids on uteri of pregnant ovariectomized hamsters were studied

Peripheral Reproductive Organ Health and Melatonin: Ready for Prime Time

Directory of Open Access Journals (Sweden)

Russel J. Reiter

2013-04-01

Full Text Available Melatonin has a wide variety of beneficial actions at the level of the gonads and their adnexa. Some actions are mediated via its classic membrane melatonin receptors while others seem to be receptor-independent. This review summarizes many of the published reports which confirm that melatonin, which is produced in the ovary, aids in advancing follicular maturation and preserving the integrity of the ovum prior to and at the time of ovulation. Likewise, when ova are collected for in vitro fertilization-embryo transfer, treating them with melatonin improves implantation and pregnancy rates. Melatonin synthesis as well as its receptors have also been identified in the placenta. In this organ, melatonin seems to be of particular importance for the maintenance of the optimal turnover of cells in the villous trophoblast via its ability to regulate apoptosis. For male gametes, melatonin has also proven useful in protecting them from oxidative damage and preserving their viability. Incubation of ejaculated animal sperm improves their motility and prolongs their viability. For human sperm as well, melatonin is also a valuable agent for protecting them from free radical damage. In general, the direct actions of melatonin on the gonads and adnexa of mammals indicate it is an important agent for maintaining optimal reproductive physiology.

Objective: To discuss the feasibility and safety of uterine artery chemoembolization in the treatment of cervical pregnancy. Methods: During the period of Sep. 2005-Dec. 2007, uterine artery chemoemboliztion was performed in 12 patients with cervical pregnancy in the authors' hospital. Via bilateral uterine arteries 100 mg MTX and 80,000 U Gentamycin were infused separately, after that the bilateral uterine arteries were embolized with gelfoam. Cleaning of the uterus and the cervix uteri was carried out in 24 -72 h after the procedure. Results: The technical success rate of bilateral uterine artery chemoembolization was 100%. The blood loss was 50-100 ml (mean 65 ml) during the procedure of cleaning the uterus and the cervix uteri. No serious complications occurred. Conclusion: Uterine artery chemoembolization is an effective and safe treatment for cervical pregnancy, which can greatly avoid unnecessary uterectomy and preserve fertility function. (authors)

Derzko-Dzulynsky, Larissa

2017-11-01

IgG4-related disease is a multi-organ fibro-inflammatory disease with characteristic histopathology showing lymphoplasmacytic infiltration, increased IgG4+ plasma cells and elevated IgG4/IgG ratios (>40%). The lacrimal gland is the most common ocular site of involvement. Scleritis and intraocular involvement in IgG4-related ophthalmic disease (IgG4-ROD) have recently been reported. The purpose of this review is to describe orbital and intraocular IgG4-ROD with a focus on publications since 2016. Case reports of scleritis and uveitis in IgG4-ROD have been described since 2012. Systemic prednisone is recommended as the first-line treatment, but immunosuppressive therapy may be required for steroid-sparing or in steroid-resistant cases. High rates of systemic IgG4-RD involvement exist in patients with bilateral IgG4-ROD or if the lacrimal gland is involved. Rituximab is the most specific immune targeted therapy available with high rates of remission. IgG4-ROD is an emerging cause of scleritis and uveitis and should be considered in any patient with multisystem inflammatory disease. New targeted immune therapies may improve outcomes and lead to clinical remission.

Diagnostic laparoscopy with chromopertubation to identify the anomaly and subsequent bilateral supracervical hemihysterectomies. Incidence, pathogenesis, fertility implications, and treatment options for patients with congenital defects in the upper vagina, cervix, and uterus. Based on classic embryology, the lower vagina forms from the urogenital sinus while the upper vagina, cervix, and uterus form from the müllerian ducts. If a cervix is present, then the upper vagina and uterus are also usually present and should communicate. This anomaly cannot be fully explained by traditional embryologic developmental theory. It is likely that an insult occurred between 9 weeks, when the uterovaginal canal is formed, and 12 weeks, when the müllerian ducts fuse. Copyright © 2011 American Society for Reproductive Medicine.

Palaoro, Luis Alberto; Guerra, Fernando; Angeleri, Anabela; Palamas, Marta; Melba, Sardi-Segovia; Rocher, Adriana Esther

2012-01-01

Objectives: To establish the cytological criteria to identify the urothelial cells in cervical smears in order to avoid mistakes in the cytological diagnosis. Materials and Methods: Cervical smears from 34 post menopausal women with vesicovaginal fistulas, advanced bladder prolapse and genital erosive lichen planes (vulvar kraurosis) (Group 1) and transitional cell metaplasia of the cervix (TCM, Group 2) were stained with Papanicolaou technique. The cervical samples were taken during the routine annual examination for prevention of the uterine cancer. Results: The smears of cervix from Group 1 showed urothelial cells from the three layers of the transitional epithelium. The umbrella cells are the bigger ones with relatively large nuclei. Frequently, they are multinucleated with single or multiple nucleoli and a typical “frothy” cytoplasm (cytoplasmic vacuoles). The cells of the Group 2 showed nuclei with oval to spindled shapes, some tapered ends, less cytoplasm than squamous metaplastic cells, powdery chromatin, small nucleoli and nuclear grooves. Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs) due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL) cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper. PMID:22438615

Growing evidence shows a causal role of high-risk humane papillomavirus (HPV) infections in the development of head and neck cancer. A recent case report shows two patients suffering from tonsillar cancer without any risk factors apart from their work as gynecologists doing laser ablations and loop electrosurgical excision procedures (LEEP). The aim of the present investigation is to evaluate whether surgical plume resulting from routine LEEPs of HSIL of the cervix uteri might be contaminated with the DNA of high-risk HPV. The prospective pilot study is done at the Department of Gynecology and Obstetrics of the University of Lübeck, Germany. The primary outcome was defined as HPV subtype in resected cone and in surgical plume resulting from LEEPs of HSIL of the cervix uteri. Plume resulting from LEEPs was analyzed using a Whatman FTA Elute Indicating Card which was placed in the tube of an exhaust suction device used to remove the resulting aerosols. For detection of HPV and analysis of its subtype, the novel EUROArray HPV test was performed. Resected cones of LEEPs were evaluated separately for HPV subtypes. Four samples of surgical plume resulting from routine LEEPs indicated contamination with high-risk HPV and showed the same HPV subtype as identified in the resected cones. Surgical plume resulting from routine LEEPs for HSIL of the cervix uteri has the risk of contamination with high-risk HPV. Further investigations of infectiousness of surgical plume are necessary for evaluation of potential hazards to involved healthcare professionals.

The aim of this study was to assess the long-term reproductive outcome following abdominal myomectomy in women with very large fibroid uteri. It is a retrospective study of 90 subfertile women with the main outcome measure of live-birth rate following spontaneous and assisted conception. Mean age of the study population was 37 ± 5 years and mean uterine size was 21 ± 6 weeks. During follow-up (mean 50 ± 10 months), 28 (31%) pregnancies occurred; 18 spontaneous and 10 following IVF. The live-birth rate was 20% and the miscarriage rate was 32%. Multivariate analysis demonstrated that the chance of live birth was significantly reduced with increasing female age at the time of surgery (OR = 0.67, 95% CI 0.51-0.86, p = 0.002). The perioperative blood transfusion rate was 30% and the incidence of major complications was 6%. Fertility after abdominal myomectomy for very large fibroid uteri is possible, and its major determinant is female age at the time of surgery.

Embryonic diapause (delayed implantation) is a reproductive strategy widespread in the animal kingdom. Under this condition, embryos at the blastocyst stage become dormant simultaneously with uterine quiescence until environmental or physiological conditions are favorable for the survival of the mother and newborn. Under favorable conditions, activation of the blastocyst and uterus ensues with implantation and progression of pregnancy. Although endocrine factors are known to participate in this process, the underlying molecular mechanism coordinating this phenomenon is not clearly understood. We recently found that uterine muscle segment homeobox (Msx) transcription factors are critical for the initiation and maintenance of delayed implantation in mice. To better understand why Msx genes are critical for delayed implantation, we compared uterine proteomics profiles between littermate floxed (Msx1/Msx2f/f) mice and mice with uterine deletion of Msx genes (Msx1/Msx2d/d) under delayed conditions. In Msx1/Msx2d/d uteri, pathways including protein translation, ubiquitin-proteasome system, inflammation, chaperone-mediated protein folding, and endoplasmic reticulum (ER) stress were enriched, and computational modeling showed intersection of these pathways on inflammatory responses. Indeed, increases in the ubiquitin-proteasome system and inflammation conformed to proteotoxic and ER stress in Msx1/Msx2d/d uteri under delayed conditions. Interestingly, treatment with a proteasome inhibitor bortezomib further exacerbated ER stress in Msx1/Msx2d/d uteri with aggravated inflammatory response, deteriorating rate of blastocyst recovery and failure to sustain delayed implantation. This study highlights a previously unrecognized role for Msx in preventing proteotoxic stress and inflammatory responses to coordinate embryo dormancy and uterine quiescence during embryonic diapause.

In this study, therefore, the placenta and nonpregnant uterus of the Antarctic minke whale were observed morphologically and immunohistochemically. Placentas and nonpregnant uteri were collected from the 15th, 16th and 18th Japanese Whale Research Programme with Special Permit in the Antarctic (JARPA) and 1st JARPA II organized by the Institute of Cetacean Research in Tokyo, Japan. In the macro- and microscopic observations, the placenta of the Antarctic minke whale was a diffuse and epitheliochorial placenta. The chorion was interdigitated to the endometrium by primary, secondary and tertiary villi, which contained no specialized trophoblast cells such as binucleate cells, and the interdigitation became complicated with the progress of gestation. Furthermore, fetal and maternal blood vessels indented deeply into the trophoblast cells and endometrial epithelium respectively with fetal growth. The minke whale placenta showed a fold-like shape as opposed to a finger-like shape. In both nonpregnant and pregnant uteri, many uterine glands were distributed. The uterine glands in the superficial layer of the pregnant endometrium had a wide lumen and large epithelial cells as compared with those in the deep layer. On the other hand, in the nonpregnant endometrium, the uterine glands had a narrower lumen and smaller epithelial cells than in the pregnant endometrium. In immunohistochemical detection, immunoreactivity for P450scc was detected in most trophoblast cells, but not in nonpregnant uteri, suggesting that trophoblast epithelial cells synthesized and secreted the sex steroid hormones and/or their precursors to maintain the pregnancy in the Antarctic minke whale.

To study the potential endocrine disrupting effects of bifenthrin (BIF) by using uterotrophic assay and Hershberger assay. In uterotrophic assay, 60 female SD rats were randomly divided into 6 groups, 10 rats per group. Rats in bifenthrin-treated groups were given different doses of bifenthrin (1.47, 4.41 and 13.23 mg/kg BW by gavage for 3 consecutive days). Rats in negative control groups were given corn oil by gavage. Rats in ethinyl estradiol (EE) oral positive control groups were given EE 1.0 microg/kg BW by gavage. Rats in EE injected positive groups were given 0.6 microg/kg BW EE by subcutaneously injection while given corn oil by gavage. At necropsy, the wet and blotted uteri were weighed. The relative uteri weights were calculated, and the histology of uteri was observed. In Hershberger assay, 60 castrated male SD rats were randomly divided into 6 groups, with 10 rats in each group. Rats in BIF-treated groups were given different doses of BIF (1.4, 4.2 and 12.6 mg/kg BW) by gavage. Flutamide (3.0 mg/kg BW) were given to animals in the positive control group by gavage. Rats in the negative control group and testosterone propionate group were given corn oil by gavage for 10 consecutive days. Rats in all groups except the negative control group were also treated with testosterone propionate (TP, 0.2 mg/kg BW) by subcutaneous injection. At necropsy, ventral prostate (VP), seminal vesicle plus fluids and coagulating glands (SVCG), levator ani-bulbocavernosus muscle (LABC), paired Cowper's glands (COW) and the glands penis (GP), liver, kidneys, adrenals were weighed. Serum triiodothyronine (T3) and thyroxine (T4) were determined. In uterotrophic assay, compared with the negative control group, the mean relative wet weight and relative blotted weight of uterine were increased significantly in the female rats given by BIF at 13.23 mg/kg BW for 3 days (P < 0.05). BIF resulted in a significant increase of epithelial cell heights of uteri at 4.41 and 13.23 mg/kg BW

Leiomyoma of the ovary is a very rare benign tumor which is usually found incidentally on routine pelvic examination, or during surgery of autopsy. We report a case of ovarian leiomyoma in a 46-year-old woman in whom a lower abdominal mass was detected. A multiloculated and multiseptated mainly cystic mass in the left adnexa was revealed by computed tomography, and was thought to be an ovarian mucinous cystadenoma. Surgical pathology, however, demonstrated that the mass was a vascular leiomyoma originating from the left ovary. (author)

Full Text Available Introduction: Leiomyoma of the fallopian tube is extremely rare, and its version – leiomyoma cellulare (LC of the fallopian tube is absolutely unique. Aim of the study was to review literature reports on leiomyomas of the fallopian tubes, and to present cases of leiomyoma and LC of the fallopian tubes in the patients operated on in our ward. Material and methods : There were fewer than 100 cases of leiomyomas of the fallopian tubes discussed in the literature up to 1993. Case 1. Leiomyoma of the left fallopian tube was detected postoperatively in a 68-year-old patient, G.K., on histopathological examination after laparoscopic total hysterectomy with bilateral adnexa.Case 2. A 56-year-old patient, K.T., with LC of the fallopian tube was qualified for laparoscopy. At operation, the procedure was converted to microlaparotomy due to the tumor size. The adnexa on the right side with the tumor of the fallopian tube were excised, and the left fallopian tube was excised, too. Histopathological microscopy found leiomyoma cellulare partim epithelioides. Results: In the presented cases, the extent of operation was connected with the clinical picture, and in the case of LC of the right fallopian tube, with intraoperative histopathological findings. In both cases the postoperative course was uneventful. Conclusions : Diagnosis of leiomyoma and LC of the fallopian tube, like in the other organs of the female genital tract, is possible only due to results of histopathological microscopy.

Highlights: •We first examined the expression of Cxcl14 in MLAp and DB of uterus. •We found the uNK cells in MLAp and decidua express Cxcl14. •In Cxcl14 −/− placenta, we found significantly decreased uNK cells. •We first performed microarray to compare the gene expression in MLAp and DB. -- Abstract: The uterine natural killer cells (uNK cells) are the major immune cells in pregnant uterus and the number of uNK cells is dramatically increased during placentation and embryo development. The uNK cells are necessary for the immune tolerance, cytokine secretion and angiogenesis of placenta. Former studies indicated that the population expansion of uNK cells was accomplished through recruitment of NK cell precursors from the spleen and bone marrow, but not proliferation of NK cells. However, the necessary molecules within this process were little understood. Here in our study, we found the co-localized expression of Cxcl14 protein with uNK cells in E13.5 pregnant uterus. Moreover, we used Cxcl14 knockout mice to examine uNK cells in mesometrial lymphoid aggregate of pregnancy (MLAp) and decidua basalis (DB) of E13.5 pregnant uterus and found significantly decreased uNK cells in Cxcl14 −/− pregnant uteri compared with Cxcl14 +/− pregnant uteri. To further explorer the molecular change in MLAp and DB after Cxcl14 knockout, we isolated the MLAp and DB from Cxcl14 +/+ and Cxcl14 −/− pregnant uteri and performed microarray analysis. We found many genes were up and down regulated after Cxcl14 knockout. In conclusion, our results suggested the important function of Cxcl14 in uNK cells and the proper level of Cxcl14 protein were required to recruit NK cells to pregnant uterus

Mehl, N S; Srisuwatanasagul, S; Swangchan-Uthai, T; Sirivaidyapong, S; Khalid, M

2017-01-01

Effect of a GnRH-agonist (deslorelin) was studied on reproductive function and ovarian luteinizing hormone receptor (LHR) and follicle stimulating hormone receptor (FSHR) expression in prepubertal female cats that were either implanted with 4.7-mg deslorelin (implanted: n = 6) or not (controls: n = 18) or ovariohysterectomized at prepubertal age (prepubertal OVH: n = 6). Body weights, fecal estradiol, and sexual behavior of implanted and control cats were monitored for 48 weeks followed by collection of ovaries and uteri. Ovaries and uteri were collected from control cats at follicular, luteal, and inactive stage (n = 6/group) and from prepubertal OVH cats at prepubertal age. Ovaries and uteri were analyzed for anatomical/histological characteristics. Ovaries were also analyzed for LHR and FSHR expression. Statistical analysis showed higher (P ≤ 0.05) body weight in control than implanted cats only during 22nd to 26th weeks of the study. Estrus was observed in control cats only. Deslorelin reduced (P ≤ 0.05) ovarian weight and number of antral follicles but did not affect endometrial thickness and gland diameter. However, myometrial thickness of implanted cats was significantly lower than control cats at follicular and luteal stage. Ovarian LHR mRNA expression was lower (P ≤ 0.05) in implanted cats than control cats at follicular stage. FSHR mRNA and LHR protein expression did not differ among the three groups. FSHR protein expression was lower (P ≤ 0.05) in prepubertal OVH cats and was not affected by deslorelin. In conclusion, deslorelin suppresses reproductive function in prepubertal female cats for at least 48 weeks possibly through a change in the ovarian mRNA expression of LHR.

To study the involvement of seven types of bone marrow-derived cells (BMDCs) in the endometrial regeneration in mice after total body irradiation. Prospective experimental animal study. University research laboratories. β-Actin-green fluorescent protein (GFP) transgenic C57BL/6-Tg (CAG-EGFP) and C57BL/6J female mice. The BMDCs were isolated from CAG-EGFP mice: unfractionated bone marrow cells, hematopoietic progenitor cells, endothelial progenitor cells (EPCs), and mesenchymal stem cells (MSCs). In addition three murine GFP(+) cell lines were used: mouse Oct4 negative BMDC multipotent adult progenitor cells (mOct4(-)BM-MAPCs), BMDC hypoblast-like stem cells (mOct4(+) BM-HypoSCs), and MSCs. All cell types were injected through the tail vein of 9 Gy-irradiated C57BL/6J female mice. Flow cytometry, cell culture, bone marrow transplantation assays, histologic evaluation, immunohistochemistry, proliferation, apoptosis, and statistical analysis. After 12 weeks, histologic analysis revealed that uteri of mice with mOct4(-)BM-MAPCs and MSC line were significantly smaller than uteri of mice with uncultured BMDCs or mOct4(+) BM-HypoSCs. The percentage of engrafted GFP(+) cells ranged from 0.13%-4.78%. Expression of Ki-67 was lower in all uteri from BMDCs treated mice than in the control, whereas TUNEL(+) cells were increased in the EPCs and mOct4(+)BM-HypoSCs groups. Low number of some BMDCs can be found in regenerating endometrium, including stromal, endotelial, and epithelial compartments. Freshly isolated MSCs and EPCs together with mOct4(+) BM-HypoSCs induced the greatest degree of regeneration, whereas culture isolated MSCs and mOct4(-)BM-MAPCs transplantation may have an inhibitory effect on endometrial regeneration.

1978-01-01

Late radiation injuries of the intestine are frequent after radiation therapy of malignant tumours of female genitalia and some other tumours due to which the intestine gets into the irradiation field. On the basis of the analysis of 80 patients with late radiation injuries of intestine which developed at remote terms after radiation therapy of cervix uteri cancer and corpus uteri (65 patients) and other tumours, peculiarities of the clinical course and treatment of radiation enterocolitis, rectosigmoidites and rectites are discussed. In 39 patients these injuries were concomitant with late radiation injuries of the skin and subcutaneous soft tissues. The clinical course of radiation unjuries of the intestine was defined by the character of the pathological process in the intestine and was more sharply marked in patients suffering from radiation enterocolites. It was established that one of the pathogenetic mechanisms of late radiation injuries of the intestine was a disorder of the absorption function of the intestine. Local treatment of radiation injuries of the intestine should be combined with a general one the important component of which is a parenteral diet

Purpose: To define a male and female pelvic normal tissue contouring atlas for Radiation Therapy Oncology Group (RTOG) trials. Methods and Materials: One male pelvis computed tomography (CT) data set and one female pelvis CT data set were shared via the Image-Guided Therapy QA Center. A total of 16 radiation oncologists participated. The following organs at risk were contoured in both CT sets: anus, anorectum, rectum (gastrointestinal and genitourinary definitions), bowel NOS (not otherwise specified), small bowel, large bowel, and proximal femurs. The following were contoured in the male set only: bladder, prostate, seminal vesicles, and penile bulb. The following were contoured in the female set only: uterus, cervix, and ovaries. A computer program used the binomial distribution to generate 95% group consensus contours. These contours and definitions were then reviewed by the group and modified. Results: The panel achieved consensus definitions for pelvic normal tissue contouring in RTOG trials with these standardized names: Rectum, AnoRectum, SmallBowel, Colon, BowelBag, Bladder, UteroCervix, Adnexa{sub R}, Adnexa{sub L}, Prostate, SeminalVesc, PenileBulb, Femur{sub R}, and Femur{sub L}. Two additional normal structures whose purpose is to serve as targets in anal and rectal cancer were defined: AnoRectumSig and Mesorectum. Detailed target volume contouring guidelines and images are discussed. Conclusions: Consensus guidelines for pelvic normal tissue contouring were reached and are available as a CT image atlas on the RTOG Web site. This will allow uniformity in defining normal tissues for clinical trials delivering pelvic radiation and will facilitate future normal tissue complication research.

When is protection from impact needed for the face as well as the eyes in occupational environments?

Science.gov (United States)

Dain, Stephen J; Huang, Rose; Tiao, Aimee; Chou, B Ralph

2018-05-01

The most commonly identified reason for requiring or using occupational eye and face protection is for protection against flying objects. Standards vary on what risk may require protection of the eyes alone and what requires protection for the whole face. Information on the minimum energy transfer for face damage to occur is not well-established. The heads of pigs were used as the common model for human skin. A 6 mm steel ball projected at velocities between 45 and 135 m/s was directed at the face area. Examples of impacts were filmed with a high-speed camera and the resulting damage was rated visually on a scale from 1 (no visible damage) to 5 (penetrated the skin and embedded in the flesh). The results for the cheek area indicate that 85 m/s is the velocity above which damage is more likely to occur unless the skin near the lip is included. For damage to the lip area to be avoided, the velocity needs to be 60 m/s or less. The present data support a maximum impact velocity of 85 m/s, provided the thinner and more vulnerable skin of the lids and orbital adnexa is protected. If the coverage area does not extend to the orbital adnexa, then the absolute upper limit for the velocity is 60 m/s. At this stage, eye-only protection, as represented by the lowest level of impact test in the standards in the form of a drop ball test, is not in question. © 2017 Optometry Australia.

Blast injury face: An exemplified review of management

Facial injuries are extremely common due to increased incidence of vehicular and industrial trauma and warfare injuries. But isolated injury to the face due to low voltage cells exploding is rare. In blast injury, the force can cause massive soft tissue injury, along with injury to facial fractures and damage to adnexa. Facial injury is not life threatening unless associated with other injuries of the skull and airway. The major risks to airway in facial trauma are due to anatomic alteration of patient's airway through bony and soft tissue disruption and increased chances of aspiration. The past several decades have seen a rapid growth in the range of procedures available for reconstructive purposes. However, the essential preliminary management is a must and needs to be structured. The patient, a 10-year-old boy, was joining three pencil batteries in series and twisting the wire with his teeth when one battery exploded causing severe injuries to midface and mandibular region. After stabilization, the patient was taken up for surgery. A cap splint with zygomatic suspension was done for the maxilla, and wiring of residual mandibular segments with lining and skin cover provided by a deltopectoral flap was done. Reconstructive surgeries for reconstruction of the upper lip and maintenance of oral continence were planned for the future. The present case stresses the importance of educating the masses about unsafe handling of low voltage devices, management of airway, massive soft tissue injury, along with facial fractures and damage to adnexa.

The pouch of Douglas may become occupied by a variety of mass-like lesions, which may be challenging to providers who treat women. These lesions may initially be thought to arise from the uterus or adnexa. We conducted a literature review using a Medline search of the terms "Douglas' pouch," "pouch of Douglas," "cul-de-sac," and "rectouterine pouch." A review of the scope of pouch of Douglas lesions is presented to assist in developing a differential diagnosis if a patient with such a lesion is encountered. Copyright © 2016 AAGL.

Full Text Available Autoamputation of the appendix has rarely been described in the literature. We present a case of a pelvic mass, thought to be a dermoid cyst based on preoperative imaging. After surgical removal and pathological examination, the mass was found to be a chronic pelvic abscess containing the right adnexa as well as an autoamputated vermiform appendix. Differentiating between gynecologic and gastrointestinal disease preoperatively can be difficult and often a definitive diagnosis cannot be made until surgical exploration and pathological review. However, to our knowledge, this is the first described case of a chronic pelvic abscess containing an autoamputated vermiform appendix.

Four types of material have been used for the quality control of routine assays of estrogen receptors in human breast tumors. Pieces of hormone-dependent Nb rat mammary tumors gave a precision about 40%. Rat uteri and rat tumors pulverized at liquid nitrogen temperature and stored as powder yielded precision about 30%. Powdered and lyophilised human tumors appear the best with precision as good as 17%.

There was performed a comparative analysis of quantitative load and physical status of human papillomavirus (HPV) type 16 in groups of patients with cervical intraepithelial neoplasia (CIN)--25 people and cervical cancer (CC)--85 people. According to the analysis there were selected criteria appropriate to a combination of adverse factors that characterized HPV- infection and at the same time estimated both quantitative load and physical status of the virus: high viral load (> 6,5 lg copies of HPV DNA per 100000 cells) in episomal form or low load (< 6,5 lg copies of HPV DNA per 100000 cells) in integrated form of the virus. According to calculations a relative chance of appearing of CC in CIN patients with unfavorable combination of factors was 7,5 times higher than in other patients.

Bisphenol-A (BPA), dichrolodiphenyltrichloroethane (DDT) and vinclozolin were found able to induce abnormal uterine contraction. The mechanisms involved remains unclear. We hypothesized that the effect of these compounds were mediated via the uterotonin pathways. Therefore, in this study, effects of BPA, vinclozolin and DDT-only and in combination with uterotonins (PGF-2?, acetylcholine and oxytocin) on the force and pattern of uterine contraction were observed.

Palacios-Zertuche, Jorge Tadeo; Cardona-Huerta, Servando; Juárez-García, María Luisa; Valdés-Flores, Everardo; Muñoz-Maldonado, Gerardo Enrique

Desmoid tumours are one of the rarest tumours worldwide, with an estimated yearly incidence of 2-4 new cases per million people. They are soft tissue monoclonal neoplasms that originate from mesenchymal stem cells. It seems that the hormonal and immunological changes occurring during pregnancy may play a role in the severity and course of the disease. The case is presented on 28-year-old female in her fifth week of gestation, in whom an abdominal wall tumour was found attached to left adnexa and uterus while performing a prenatal ultrasound. The patient was followed up under clinical and ultrasonographic surveillance. When she presented with abnormal uterine activity at 38.2 weeks of gestation, she was admitted and obstetrics decided to perform a caesarean section. Tumour biopsy was taken during the procedure. Histopathology reported a desmoid fibromatosis. A contrast enhanced abdominal computed tomography scan was performed, showing a tumour of 26×20.5×18cm, with well-defined borders in contact with the uterus, left adnexa, bladder and abdominal wall, with no evidence of infiltration to adjacent structures. A laparotomy, with tumour resection, hysterectomy and left salpingo-oophorectomy, components separation techniques, polypropylene mesh insertion, and drainage was performed. The final histopathology report was desmoid fibromatosis. There is no evidence of recurrence after 6 months follow-up. Desmoid tumours are locally aggressive and surgical resection with clear margins is the basis for the treatment of this disease, using radiotherapy, chemotherapy and hormone therapy as an adjunct in the treatment.

2010-01-01

Objective: To analyze the clinical features and prognosis of patients with stage I E /II E nongastric mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: Between 2000 and 2006, 40 patients with previously untreated nongrastric MALT lymphoma were retrospectively reviewed. The primary site of lymphoma was the intestinal tract in 10 patients, the orbit in 9, the thyroid in 8, the lung in 5, the Waldeyer ring in 2, and the others organs in 6. At diagnosis, 27 patients had stage I E , and 13 had stage II E disease. Seventeen patients were treated with radiotherapy with or without chemotherapy, 18 with chemotherapy without radiotherapy, and 5 with surgery alone. The median age was 54 years. The ratio of male to female was 2: 1. Results: With a median follow-up of 58 months, the estimated 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 86% and 82%, respectively. The 5-year OS and PFS rates were 92% and 85% for stage I E , 76% and 82% for stage II E disease, respectively (χ 2 =3.66, P =0. 060; χ 2 =1.04, P=0. 300). The 5-year OS and PFS rates were both 100% for patients with MALT lymphoma of the orbit and ocular adnexa. None of the 17 patients with radiotherapy had locoregional relapse, whereas 3 of 23 (13%) patients without radiotherapy had locoregional relapse. Conclusions: Patients with stage I E nongastric MALT lymphoma have a favorable prognosis. Radiotherapy is still a standard care for early stage disease. The treatment outcome of patients with MALT lymphoma of the orbit and ocular adnexa is even better. (authors)

Hessen, Michelle; Akpek, Esen Karamursel

2014-01-01

Keratoconjunctivitis sicca, or dry eye, is a common ocular disease prompting millions of individuals to seek ophthalmological care. Regardless of the underlying etiology, dry eye has been shown to be associated with abnormalities in the pre-corneal tear film and subsequent inflammatory changes in the entire ocular surface including the adnexa, conjunctiva and cornea. Since the recognition of the role of inflammation in dry eye, a number of novel treatments have been investigated designed to inhibit various inflammatory pathways. Current medications that are used, including cyclosporine A, corticosteroids, tacrolimus, tetracycline derivatives and autologous serum, have been effective for management of dry eye and lead to measurable clinical improvement.

To characterize the anatomical features and clinical settings of Mayer-Rokitansky-Kuester-Hauser (MRKH) syndrome and correlate them with patterns of uterine involvement. Pelvic magnetic resonance images and medical records of 92 MRKH patients were retrospectively reviewed. Patients were subgrouped by uterine morphology: uterine agenesis, unilateral rudimentary uterus and bilateral rudimentary uteri. Uterine volume, presence of endometrium, location of ovary, endometriosis and pelvic pain were compared among groups. The mean uterine volume was 33.5 ml (17.5-90.0 ml) for unilateral uterine remnants, and 16.1 ml (3.5-21.5 ml) for bilateral uterine rudiments (p<0.01). The incidence of presence of endometrium (100% vs. 22%, p<0.001), haematometra (56% vs. 3%, p<0.001) and ovarian endometriosis (22% vs. 3%, p<0.01) was significantly increased in the group of unilateral rudimentary uteri as compared with the group of bilateral uterine remnants. Thirty-one patients (38%) showed ectopic ovaries. Pelvic pain was more common in individuals with unilateral rudimentary uterus than those who had no (56% vs. 5%, p<0.01) or bilateral uterine remnants (56% vs. 14%, p<0.05). MRKH patients with different patterns of uterine involvement may have differentiated anatomical features and clinical settings. (orig.)

Cell proliferation-associated tumour markers are considered to have a valuable clinical significance. The current study was designed to investigate changes in immunohistochemical (IH) expression of proliferating cell nuclear antigen PCNA in human malignant tumour tissue samples obtained before and after preoperative radiotherapy. Tumour tissue samples were obtained from 26 patients with rectal carcinoma, from 22 patients with carcinoma corporis uteri and from 82 patients with breast cancer. Tumour samples were processed for IH examination by using monoclonal antibodies (MoAbs) PC10 against PCNA. IH analysis of histological specimens of carcinoma corporis uteri and rectal carcinoma obtained before and after preoperative radiotherapy has revealed heterogeneity of biological response to irradiation. The great majority of tumour specimens after irradiation showed a high PCNA expression level in cell population. Only minority of tumour specimens (15-20%) exhibited reduced immunoreactivity with MoAbs PC10. PCNA positivity rate in breast cancer specimens obtained during surgery from 55 patients after preoperative radiotherapy in comparison to biomarker expression pattern in tumour specimens from 27 unirradiated patients (control group) was found to be tended to decrease. These in vivo findings are discussed in terms of radiation-induced cell death, followed after proliferation, and PCNA role in DNA repair. (author)

In the recent decades, laparoscopy has replaced open abdominal procedures in the setting of gynecologic surgery. Extraction of large specimens (e.g., large uteri or myomas) following operative laparoscopy is technically challenging. Technological attempts allow the removal of large and solid pelvic masses via small abdominal incisions (using instruments called morcellators), thus reducing unnecessary laparotomies and improving short-term patients' outcomes. However, morcellation of undiagnosed uterine malignancies may lead to worse survival outcomes. Therefore, the Food and Drug Administration (FDA) warns about the use of power morcellators, thus causing ongoing concerns on the applicability of minimally invasive approaches for myomectomy and the removal of large uteri. In the present review, we sought to assess pro and cons regarding minimally invasive morcellation. This review will discuss the effects of morcellation of undiagnosed uterine malignancies, focusing on possible techniques for preoperative detection of uterine sarcoma and for avoiding intra-abdominal dissemination of potentially malignant tissues. Further efforts are necessary in order to identify tools to make a more accurate and reliable preoperative diagnosis of uterine masses. However, on the light of the current evidence, intra-abdominal morcellation should be banned from clinical practice. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

CA 125 is a tumor-associated antigen. Its high levels are usually associated with ovarian malignancies, whereas smaller increases in the levels were associated with benign gynecologic conditions. The authors report a high level of CA 125 in a case of large ovarian endometrioma. A 45-year-old nulliparous Thai woman, presented with an increase of her abdominal girth for 7 months. Transabdominal ultrasonogram demonstrated a large ovarian cyst and multiple small leiomyoma uteri, and serum CA 125 level was 1,006 U/ml. The preoperative diagnosis was ovarian cancer with leiomyoma uteri. Exploratory laparotomy was performed. There were a large right ovarian endometrioma, small left ovarian endometrioma and multiple small leiomyoma. Total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed and histopathology confirmed the diagnosis of endometrioma and leiomyoma. The serum CA 125 level declined to non-detectable at the 4th week. She was well at discharge and throughout her 4th week follow-up period Although a very high level of CA 125 is associated with a malignant process, it can also be found in benign conditions such as a large endometrioma. The case emphasizes the association of high levels of CA 125 with benign gynecologic conditions.

Three cases with carcinoma colli uteri, in whom radiotherapy during the postoperative period was used, are described. Radionecrosis developed at various periods after the radiotherapy - in one of the cases on the wall of intestine and in the other two - on the wall of the rectum. Death occurred as a result of these complications in the three cases. These early radiation necrosis developed most probably in connection with an increased individual radiosensitivity. (author)

Full Text Available This study aimed to determine the changes in the biometry of the ovaries, of the uteri and its contents in the Maradi doe-goat during the three terms of pregnancy. Pregnant uteri from 28 female goats and their corresponding ovaries were used to study the biometric changes in the ovaries, gravid uteri, amniotic and allantoic fluids volumes, fetuses and plancentomes during the three terms of pregnancy. The results revealed that there was no significant variation in the ovarian weight during the three terms of pregnancy. However, there were significant variations in the ovarian length (left ovary 2.15 ± 0.16 cm; right ovary 2.10 ± 0.10 cm and width (left ovary 1.77 ± 0.19 cm; right ovary 1.60 ± 0.10 cm in the third term of pregnancy compared to the ovarian length and width in the first term of pregnancy. The uterine weight showed significant variation in the first term, second term   and in the third term of pregnancy. The uterine length of both horns also showed significant variations in the first term (left side 31.40 ± 1.79 cm; right side 28.22 ± 0.98 cm, second term (left side 51.58 ± 4.14 cm; right side 50.51 ± 3.62 cm and in the third term (left side 70.67 ± 1.76 cm; right side 80.38 ± 2.75 cm of pregnancy but only in the third term of pregnancy was a significant difference in the lengths of the left side uterine horn (70.67 ± 1.76 cm compared to the right side (80.38 ± 2.75 cm. The number of plancentomes was constant in both uterine horns throughout gestation; however the mean caruncular diameter increased progressively from the first term of gestation through the third term of pregnancy. The smallest and largest caruncles were observed on the ventral surfaces of the uterine horns, and the plancentomes were observed to be aligned in a linear manner along the longitudinal axis of the uterine horns. This study shows that there are differences in the biometrics of the ovary and uterus in Maradi goats compared to some other breed.

Amniotic fluid represents an abundant source of multipotent stem cells, referred as broadly multipotent given their differentiation potential and expression of pluripotency-related genes. However, the origin of this broadly multipotent cellular fraction is not fully understood. Several sources have been proposed so far, including embryonic and extraembryonic tissues. In this regard, the ovine developmental model uniquely allows for direct comparison of fetal fluid-derived cells from two separate fetal fluid cavities, the allantois and the amnion, over the entire duration of gestation. As allantoic fluid mainly collects fetal urine, cells originating from the efferent urinary tract can directly be compared with cells deriving from the extraembryonic amniotic tissues and the fetus. This study shows isolation of cells from the amniotic [ovine amniotic fluid cells (oAFCs)] and allantoic fluid [ovine allantoic fluid cells (oALCs)] in a strictly paired fashion with oAFCs and oALCs derived from the same fetus. Both cell types showed cellular phenotypes comparable to standard mesenchymal stem cells (MSCs), with trilineage differentiation potential, and expression of common ovine MSC markers. However, the expression of MSC markers per single cell was higher in oAFCs as measured by flow cytometry. oAFCs exhibited higher proliferative capacities and showed significantly higher expression of pluripotency-related genes OCT4, STAT3, NANOG, and REX1 by quantitative real-time polymerase chain reaction compared with paired oALCs. No significant decrease of pluripotency-related gene expression was noted over gestation, implying that cells with high differentiation potential may be isolated at the end of pregnancy. In conclusion, this study suggests that cells with highest stem cell characteristics may originate from the fetus itself or the amniotic fetal adnexa rather than from the efferent urinary tract or the allantoic fetal adnexa.

Purpose: Low-dose radiation has become increasingly used in the management of indolent non-Hodgkin lymphoma (NHL), but has not been studied specifically for cases of ocular adnexal involvement. The objective of this study is to investigate the effectiveness of low-dose radiation in the treatment of NHL of the ocular adnexa. Methods and Materials: We reviewed the records of 20 NHL patients with 27 sites of ocular adnexal involvement treated with low-dose radiation consisting of 2 successive fractions of 2 Gy at our institution between 2005 and 2011. The primary endpoint of this study is freedom from local relapse (FFLR). Results: At a median follow-up time of 26 months (range 7-92), the overall response rate for the 27 treated sites was 96%, with a complete response (CR) rate of 85% (n=23) and a partial response rate of 11% (n=3). Among all treated sites with CR, the 2-year FFLR was 100%, with no in-treatment field relapses. The 2-year freedom from regional relapse rate was 96% with 1 case of relapse within the ipsilateral orbit (outside of the treatment field). This patient underwent additional treatment with low-dose radiation of 4 Gy to the area of relapse achieving a CR and no evidence of disease at an additional 42 months of follow-up. Orbital radiation was well tolerated with only mild acute side effects (dry eye, conjunctivitis, transient periorbital edema) in 30% of treated sites without any reports of long-term toxicity. Conclusions: Low-dose radiation with 2 Gy × 2 is effective and well tolerated in the treatment of indolent NHL of the ocular adnexa with high response rates and durable local control with the option of reirradiation in the case of locoregional relapse.

To describe the epidemiology of illness at the Sochi 2014 Winter Paralympic Games. A total of 547 athletes from 45 countries were monitored daily for 12 days over the Sochi 2014 Winter Paralympic Games (6564 athlete days). Illness data were obtained daily from teams without their own medical support (13 teams, 37 athletes) and teams with their own medical support (32 teams, 510 athletes) through electronic data capturing systems. The total number of illnesses reported was 123, with an illness incidence rate (IR) of 18.7 per 1000 athlete days (95% CI 15.1% to 23.2%). The highest IR was reported for wheelchair curling (IR of 20.0 (95% CI 10.1% to 39.6%)). Illnesses in the respiratory system (IR of 5.6 (95% CI 3.8% to 8.0%)), eye and adnexa (IR of 2.7 (95% CI 1.7% to 4.4%)) and digestive system (IR of 2.4 (95% CI 1.4% to 4.2%)) were the most common. Older athletes (35-63 years) had a significantly higher IR than younger athletes (14-25 years, p=0.049). The results of this study indicate that Paralympic athletes report higher illness incidence rates compared to Olympic athletes at similar competitions. The highest rates of illness were reported for the respiratory and digestive systems, eye and adnexa, respectively. Thus, the results of this study form a basis for the identification of physiological systems at higher risk of illness, which can in turn inform illness prevention and management programmes with eventual policy change to promote athlete safety in future editions of the Winter Paralympic Games.

To examine the efficacy of YuanHu painkillers (YHP) as a treatment for primary dysmenorrhea and to reveal YHP's principle formula. A Wistar rat uterine contraction model was utilized in this study. Rats were given 0.698g/kg YHP, 0.07g/kg tetrahydropalmatine (THP; YHP's main component), 0.02g/kg imperatorin (IMP), or THP+IMP (0.07+0.02g/kg) as polypharmacy (PG) by gavage. H&E staining and histopathological examination of the uteri tissue samples were performed. We then detected superoxide dismutase (SOD) and malondialdehyde (MDA), nitric oxide (NO), as well as inducible nitric oxide synthase (iNOS), i-κB, nuclear factor-κB (NF-κB), and cyclooxygenase-2 (COX-2) indices. PG significantly inhibited the uterine contraction of the primary dysmenorrhea rat model (peffects on primary dysmenorrhea in rats and remarkably alleviated the severity of experimental primary dysmenorrhea. The combined strategy proved to be more effective than either THP or IMP alone and may have synergistic effects in combination in primary dysmenorrhea. Mechanisms that might account for the beneficial effects include abating oxidative stress, inhibiting over-inflammatory reaction, and alleviating the contraction of isolated rat uteri by inhibiting the influx of extracellular Ca(2+). Broad potential for future clinical practice is foreseeable. Copyright © 2013 Elsevier GmbH. All rights reserved.

Short term post-partum heat stress in dairy cows

1980-06-01

Since many dairy cows calve during late summer, the objective was to determine if heat stress immediately post-partum would (1) alter metabolism, thus, increasing susceptibility to metabolic disorders, (2) affect lactation and/or (3) affect reproduction. Forty four cows, calving during late summer, were paired with one member of each pair stressed (HS) for the first 10 post-partum days in a hot barn. Controls (CC) were kept in a cooled section of the barn. Plasma drawn weekly for 7 weeks was analyzed in an autoanalyzer for calcium, inor. phosphorus, protein, glucose and cholesterol and by radioimmunoassay for cortisol and progesterone. Ovaries and uteri were palpated weekly. Rectal temperatures were significant higher for HS during the first 10 post-partum days. No significant effects on plasma constituents were observed during the 10-day treatment period. For the 7-week period, glucose and cholesterol were lower in HS, as were cyclic peaks of progesterone and cortisol. Both calcium and inorganic phosphorus remained clinically low for the 7 weeks, but no treatment effects were seen. Uteri of HS involuted more rapidly than the CC. Treatment did not affect reproductive efficiency. Lactation milk yields did not differ, but milk fat percent was lower in HS. Heat stress immediately post-partum altered lipid metabolism, but the animal's compensatory mechanisms prevented reduction in milk production or reproductive efficiency.

The assisted reproductive technology was initially considered to be a treatment tool for infertile couples. However, as it was started in time to use the uteri of other women for the embryos of the other ones, the concept of surrogate maternity appeared.The surrogate maternity is practiced in three types. In the first type of surrogate maternity, the sperm of the spouse of the prospective mother is inseminated with the ovum of the surrogate mother. The second method is the in-vitro inseminati...

Type II endometrial carcinomas are estrogen independent, poorly differentiated tumors that behave in an aggressive manner. Since TP53 mutation and CDH1 inactivation occur in 80% of human endometrial type II carcinomas, we hypothesized that mouse uteri lacking both Trp53 and Cdh1 would exhibit a phenotype indicative of neoplastic transformation. Mice with conditional ablation of Cdh1 and Trp53 (Cdh1d/dTrp53d/d ) clearly demonstrate architectural features characteristic of type II endometrial c...

The phylogenetic distribution, anatomy and histology of the post-cloacal bones and adnexa of geckos.

Post-cloacal bones of gekkotans may be present as a single (medial) pair, two pairs (medial and lateral), or may be lacking. We, herein, demonstrate that the presence of a single medial pair is the ancestral condition for the Gekkota, that the lateral pair is of sporadic occurrence within and between families, except for the Eublepharidae where it is universal, and that absence is also of sporadic occurrence except for the Sphaerodactylidae where it is the ancestral condition. Adult male Tokay geckos (Gekko gecko) possess only the medial pair of bones, and these exhibit a regionally-specific expression of woven, fibrolamellar, and lamellar bone, and an enclosed medullary cavity. Females and small juvenile males lack bony elements but exhibit a conspicuous band of dense connective tissue located about the anterior and lateral margins of the cloacal sacs. As males grow and attain sexual maturity, the medial post-cloacal bones condense in this band of dense connective tissue, and are thus shown to be dermal ossifications, similar to osteoderms but with muscular associations (although this is also known for crocodylians). Based upon ontogenetic data we set forth a scenario to explain the loss of the medial post-cloacal bones in various lineages. Differential staining of the cloacal sacs failed to reveal any specialized glandular structures. Investigation of the post-cloacal spurs shows them to be associated with cellular connective tissue of a type similar to that found in the vicinity of the medial post-cloacal bones. This suggests that the lateral post-cloacal bones may also be dermal bones, but histological evidence is needed to corroborate this. © 2015 Wiley Periodicals, Inc.

The two neighboring southwestern states of India, Karnataka and Maharashtra, have high incidence of HIV/AIDS and are among the six most high prevalence HIV infected states. In Karnataka state, the northern districts of Bagalkot, Belgaum and Bijapur (the three Bs) and in Maharashtra state, the southern districts of Sangli, Satara, and Solapur (the three Ss) are the areas with the highest incidence of HIV/AIDS. We have evaluated the incidence of maternal to child transmission (MTCT) of HIV-1 infection in Belgaum District which is more than 500 kilometers distance by road from the campus in greater Bangalore (Karnataka State). We have obtained the prenatal CD4 counts of HIV infected pregnant mothers. We have also screened the HIV infected children in two orphanages (rehabilitation centres for HIV infected children) in Belgaum District. The clinical conditions of these infected children were assessed for their CD4 counts, anti-retroviral therapy (ART) intake status, outpatient illnesses and body composition. We have observed that there is an influence of the age factor on the CD4 counts of the HIV infected children. Further, in view of the role of our recently found involvement of sulfatide, 3-O- galactosylceramide, in inhibition of HIV-1 replication and enhancement of hematopoiesis which is otherwise inhibited due to such infection, we have discussed the possible role of sulfatides that biologically occur in the fetal adnexa (placentatrophoblasts /amnion/chorion-umbilical cord), in containing HIV infection as a potential safer alternative to the ART regimens currently approved to be clinically practiced. Lastly, we have discussed the complementary and alternative medicine (CAM) therapies such as evidence based yoga and ayurveda as add-on to ART in potential elimination of MTCT of HIV infection. Out of a total of 150 children delivered by HIV infected mothers, 13 children were found to be positive as determined by the dried blood smear (DBS) for virological testing

Small cell carcinoma of the ovary (SCCOHT) is a rare tumor typically affecting young women. It is a highly malignant tumor accompanied with poor prognosis, early relapse and low survival rates. The most significant prognostic factor is stage of the disease. Due to above mentioned factors there are no guidelines for therapy of this rare tumor. We present a case of 22-years-old patient initially treated with antibiotics under diagnosis of pelvic inflammatory disease. Due to persistent mass at left adnexa, she was indicated for diagnostic laparoscopy, converted to laparotomy and left adnexectomy with frozen section revealing unspecified malignant tumor of left ovary. A conservative operation was performed and, after diagnosis of SCCOHT was established, the patient was indicated for adjuvant chemotherapy.

Rupture of the extraocular muscle in the absence of significant injury to the eyeball and adnexa is uncommon. The authors report a case of blunt trauma of the eyeball associated with an inferior oblique muscle and an inferior rectus muscle rupture. A 55-year-old man slipped and fell down hitting his eye on an extended windshield wiper blade. Although he had treatment in the emergency room, he complained of diplopia in the primary position 1 day postoperatively. After noticing ruptures of the inferior oblique muscle and an inferior rectus muscle during exploratory surgery, the authors carefully repaired it. Diplopia in the primary position had disappeared within 1 month after the operation and by 6 months postoperatively. The movement of the eye had almost completely recovered.

Full Text Available Purpose. External ophthalmomyiasis (EO is caused by infesting larvae belonging to various species of flies. Most documented cases result from sheep (Oestrus ovis and Russian (Rhinoestrus purpureus botfly larvae, but we recently discovered a rare case of EO caused by flesh fly (Sarcophaga argyrostoma larvae. Here, we report the case of a patient with EO who had been hospitalized and sedated for 1 week because of unrelated pneumonia. Methods. Case report. Results. A total of 32 larvae were removed from the adnexae of both eyes. Larvae identification was confirmed through DNA analysis. Treatment with topical tobramycin resulted in complete resolution of EO. Conclusion. EO can be caused by S. argyrostoma, and the elderly and debilitated may require extra ocular protection against flies during sedation.

MRI (Magnetic Resonance Imaging) is useful facilitation to perform analysis of tissue structures with the gray scale. By use of super-conducting MRI with 0.5T resistive magnet, present study was designed to analyse characteristic features of the human uterus throughout menstrual cycle. Both T 1 and T 2 values of the endometrium, the junctional zone and the myometrium were estimated on total nine volunteers of nomal healthy women aged from 21 to 30 y.o. during menstrual cycle. MRI was taken in the mid ∼ late proliferative, the secretory, and the menstrual stage. Moreover, relative square ratio of the endometrium and the junctional zone to the corpus uteri were measured by computed image analyser (Lusex 500). Following results were obtained. 1) Both T 1 and T 2 values of the endometrium and the junctional zone were lowest in the menstrual phase. In the myometrium, T 1 values were shown as same tendency comparing with the above two layers but T 2 values were lowest in the proliferative phase and the menstrual one. 2) Proportional values of the endometrium to the corpus uteri increased from 13.8% in the proliferative phase to 17.9% in the secretory phase and decreased to 8.0% in the menstrual phase. While that in the junctional zone decreased from 26.6% to 23.4% in secretory phase and increased to 35.0% in the menstrual phase. (author)

Inherited mutations in BRCA1 and BRCA2 increase significantly the risk of developing breast and ovarian cancers, and they have been associated with increased risks of developing other types of cancer. Although screening programs have been implemented in order to detect cancers at the early stage, they resulted ineffective. To date, risk-reducing bilateral salpingo-oophorectomy represents the only procedure allowing reducing the incidence of ovarian cancer and increasing survival among BRCA1 and -2 mutation carriers. In the present review we will discuss the advantages and disadvantages related to the execution of prophylactic surgery, thus underlying possible beneficial and detrimental effects of this kind of surgery in premenopausal women. Additionally, we will investigate further therapeutic strategies aimed to reduce the risk of developing ovarian cancer, without affected patients' hormonal status.

Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.

Although zearalenone (ZEN; Sigma Chemicals, St Louis, Missouri) is a well-known mycotoxin with estrogenic activity, the toxic effects of ZEN during pregnancy are unknown. This study compared the effects of daily subcutaneous injections of ZEN (2, 4, or 8 mg/kg) with those of 17β-estradiol (E2; [Sigma Chemicals] 0.8, 1.6, or 3.2 μg/kg) in mice. Injections were administered on gestational days (GDs) 1 to 5, the period including implantation which is sensitive to hormonal balance. The effects of ZEN or E2 were evaluated by comparing the number of live fetuses, their weight, and absorbed conceptuses on GD 18, with those in vehicle-treated controls. In addition, implantation, embryos in the oviducts and those in uteri without implantation sites were investigated on GD 5. In mice treated with the highest dose of ZEN or E2, decidual responses and plasma progesterone concentrations were measured on GDs 5 and 6, respectively, and delayed implantation was investigated on GDs 9 and 14. The results showed that treatment with ZEN, in a manner similar to that seen for E2, led to obstruction of essential processes for establishing and maintaining pregnancy, such as embryo migration from oviducts to uteri, the decidual response, and activation of luteal function. Zearalenone also induced delayed implantation and loss of conceptuses and at low doses caused a retarded growth of the fetuses after normal implantation. It was therefore concluded that ZEN causes multiple estrogenic toxic actions when administered during early pregnancy in mice.

To document normal measurements (length, width, anteroposterior (AP) diameter) and proportions of the non-pregnant uterus according to age and gravidity. We hypothesized that uterine proportions conform to the classical 'golden ratio' (1.618). This was a retrospective study of ultrasonographic measurements of the length, width and AP diameter of non-pregnant uteri recorded in our database between 1 January 2000 and 31 July 2012. All patients for whom abnormal findings were reported were excluded and only the first set of measurements for each patient was retained for analysis. Loess (local regression) analysis was performed using age and gravidity as explanatory variables. Measurements of 5466 non-pregnant uteri were retrieved for analysis. The mean length was found to increase to 72 mm at the age of 40 and decrease to 42 mm at the age of 80 years. Gravidity was associated with greater uterine length, width and AP diameter. Mean length/width ratio was found to be 1.857 at birth, decreasing to 1.452 at the age of 91 years. At the age of 21 years, the mean ratio was found to be 1.618, i.e. equal to the golden ratio. Increasing gravidity was associated with lower mean length/width ratio. Uterine size in non-pregnant women varies in relation to age and gravidity. Mean length/width ratio conformed to the golden ratio at the age of 21, coinciding with peak fertility. Copyright © 2013 ISUOG. Published by John Wiley & Sons Ltd.

Anthropometric indices associated with childhood growth and height attained in adulthood, have been associated with an increased incidence of certain malignancies. To evaluate the cancer-height relationship, we carried out a study using international data, comparing various cancer rates with average adult height of women and men in different countries. An ecological analysis of the relationship between country-specific cancer incidence rates and average adult height was conducted for twenty-four anatomical cancer sites. Age-standardized rates were obtained from GLOBOCAN 2008. Average female (112 countries) and male (65 countries) heights were sourced and compiled primarily from national health surveys. Graphical and weighted regression analysis was conducted, taking into account BMI and controlling for the random effect of global regions. A significant positive association between a country's average adult height and the country's overall cancer rate was observed in both men and women. Site-specific cancer incidence for females was positively associated with height for most cancers: lung, kidney, colorectum, bladder, melanoma, brain and nervous system, breast, non-Hodgkin lymphoma, multiple myeloma, corpus uteri, ovary, and leukemia. A significant negative association was observed with cancer of the cervix uteri. In males, site-specific cancer incidence was positively associated with height for cancers of the brain and nervous system, kidney, colorectum, non-Hodgkin lymphoma, multiple myeloma, prostate, testicular, lip and oral cavity, and melanoma. Incidence of cancer was associated with tallness in the majority of anatomical/cancer sites investigated. The underlying biological mechanisms are unclear, but may include nutrition and early-life exposure to hormones, and may differ by anatomical site.

The herbal agent celandine is thought to have mainly spasmolytic effects, but in the uterus it is regarded as promoting contractions, which can offer promising and innovative options for optimizing artificial reproduction. The aim of the present study was to investigate the effect of celandine on the uterine muscle, using a perfusion model of swine uteri. Sixteen swine uteri were perfused with Krebs-Ringer solution. Celandine (Chelidonium, Paverysat; Johannes Bürger Ysatfabrik Ltd., Bad Harzburg, Germany) was administered at increasing dosages. Intrauterine pressure (IUP) was recorded using an intrauterine double-chip microcatheter (Urobar 8 DS-F, Raumedic, Rehau AG & Co., Rehau, Germany). Differences in pressure (ΔP) and area under the curve (ΔAUC) after drug administration in the uterine body and uterine horn in the various dilution series were noted. A paired Student's t-test was used to evaluate differences between groups, with significance set at P<0.05. A significant initial increase in uterine activity was visible at each dosage. Inhibition of uterine activity was seen over longer periods of 5 and 10 min, particularly for a medium-dose range of 1-2mg/ml. At a dosage of 2mg/ml in particular, celandine almost always led to significant values. Following intra-arterial administration in a swine uterus perfusion model, celandine initially causes a significant increase in contractility, which is followed over time by a relaxation phase. This suggests interesting hypotheses on whether Chelidonium majus might be used to promote targeted sperm transport. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

We have studied the propotions of displacements from fetal cerebral parts during simulated intrauterine pressure. Stillborn children from the death to the experiments last only some hours, were put in cephalic position in our birth model. The cavum uteri was simulated by a metal cylinder, in which we gave compressed air for simulating the labor. The pressure was held about 100 mm Hg. A rubber cuff was fixed on the metal cylinder and let an opening of 8 cm, simulating the cervix uteri. The model with the death infant in it was frozen and than the fetal head sectioned in slides of 1,5 cm in the right of the birth pressure axis. We found, that the gyri occipital were widened, opposite the gyri frontal were compressed. Parieto-occipital we found a venous blood congestion. The brain stem was kinked and displaced dorsal. In one case we carried out in the meantime an aniogram. The cerebral vessels became under the pressure elongated. This was reversible by decrease of the pressure. The limitation of such model studies are give in some facts. We do not know, how much the loosening of the skull, following the fetal death, leads to a more than normal shifting. We further do not know, which proportions of the displacements of the cerebral substance during labor from the fetus could be compensated. Our findings suggest, that it is possible, that cerebral blood flow will be altered by displacements of the cerebral masses during intrauterine pressure. But we have not exact informations about it.

However, gynecologists have been provided with interesting insights on its pathobiology, which are the basis for uterine-preserving therapies. The aim of this paper is to discuss the latest evidence on these mechanisms and its importance in the clinical practice. A comprehensive literature search was made in Pubmed, Medline, the Cochrane Library, Orbis plus and Google Scholar for articles related to the epidemiological, biological, and genetic bases. There is extensive evidence that genetic, epigenetic, hormonal, environmental, proinflamatory, angiogenetic, and growing factors are involved in the biology of myomatosis. Such factors are capable of activating and promoting inhibitory signaling pathways leading to initiation, development, and regression of myomata through changes in myometrial cells and myomata fibers, such as cellular proliferation, differentiation, apoptosis, angiogenesis, and changes in the surrounding environment. A good understanding of the pathobiologic mechanisms of myomatosis gives reasons to physicians to elect conservative or combined therapies, and allow affected women to receive an individualized management, according to age, reproduction desire, and clinical condition.

To determine the demographic pattern and clinical presentation of 23 infertile women with intraoperative diagnosis of adenomyosis followed by histopathologic confirmation. A review of 23 consecutive infertile women that underwent surgery due to preoperative misdiagnosis for uterine fibroids over a period of 5 years. The patients mean age was 37.3 years with age range of 26 to 47 years. Only five patients (21.7%) had delivered before. Eighteen patients (78.3%) had had abortion(s) in the past. Secondary infertility accounted for 78.3% and 21.7% had primary infertility. Past gynaecological procedures included dilatation and curettage or manual vacuum aspiration in 17 (73.9%) patients, previous adhesiolysis for uterine synaechiae in 3 (13.1%) patients and past history of myomectomy in 5 (21.7%) patients. Preoperative hysterosalpingogram showed only 2 patients (8.7%) with bilateral tubal patency and 17 patients (73.9%) had bilateral tubal blockage. Unilateral patency of the fallopian tube was observed in 4 (17.4%) patients. Amongst patients with bilateral tubal blockage, cornual blockages were mostly encountered in 15 (88.2%) of the 17 patients. The modes of clinical presentation were abdominopelvic mass 100%, dymenorrhoea 82.6%, menorrhagia 60.9%, dyspareunia 47.8% and metrorrhagia in 34.8% of cases. Intraoperatively adenomyosis encountered were diffuse adenomyosis in 13 (56.5%) patients, multiple focal adenomyosis in 7 (30.4%) patients and unifocal adenomyosis in 3 (13.1%) patients. Co-existing uterine fibroid were found in 17 (73.9%) of the 23 patients. Two patients (8.7%) had coexisting endometriosis. At surgery, significant pelvic adhesion was encountered in 7 (30.4%) patients. In infertile women, adenomyosis is significantly associated with proximal tubal occlusion and tends to co-exist with insignificant uterine fibroids. (author)

A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately. This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomized trials. In total, 35 scientific articles are included, involving 7,952 patients. The results were compared with those of a similar overview from 1996 including 34,024 patients. The conclusions reached can be summarized in these points: There are limited scientific data supporting that postoperative pelvic radiotherapy improves disease-free survival in early cervical cancer. No firm conclusion can be drawn. There is moderate scientific evidence that external beam radiotherapy combined with brachytherapy gives a similar disease-free and overall survival rate as radical hysterectomy in early cervical cancer. There is strong scientific evidence that concomitant radiochemotherapy improves disease-free and overall survival compared to radiotherapy alone in early cervical cancer. The NCI has recently published an announcement stating that cisplantin-based chemotherapy should be used concomitantly with radiotherapy in cervical cancer. No solid documentation for this statement can be found concerning locally advanced stages (>IIB). There is a strong scientific evidence that cisplatin-based chemotherapy given concomitantly with radiotherapy is superior to concomitant chemotherapy with hydroxyurea. There is no scientific evidence to show that neoadjuvant chemotherapy followed by radiotherapy improves disease-free or overall survival compared to radiotherapy alone in patients with localized cervical cancer. There is moderate scientific evidence that high-dose-rate brachytherapy gives the same local control rate as low-dose-rate brachytherapy but with fewer rectal complications.

Full Text Available Collagen density is one important factor in uterine prolapse. Several studies has shown that uterine prolapse patients have lower uterosacral ligament collagen density. The purpose of this study was to reveal the uterosacral ligament collagen density differences in patients with and without uterine prolapse. This case control study was an analitic comparative research of 16 uterine prolapse patients and 16 patients without uterine prolapse who underwent hysterectomy in Dr. Hasan Sadikin General Hospital Bandung and its networking hospitals during November–December 2008. Uterosacral ligament was sampled and then stained using HE and Masson’s trichrome staining. The significance of the result was analyzed using Mann-Whitney. The study found a significant correlation between collagen density and uterine prolapse, with the collagen density of uterine prolapse patients was lower (15.3% than patients without uterine prolapse (48.75%. The uterosacral ligament collagen density cut-off point in predicting women having uterine prolapse was ≤30%; with 93.8% sensitivity, 87.5% specificity, and 90.6% accuracy. The conclusion of this study is that uterosacral ligament collagen density in patients with uterine prolapse is lower (15.3% than patients without uterine prolapse (48.75%. The uterosacral ligament collagen density cut-off point in predicting a women having uterine prolapse is ≤30%.

Adenoid cystic carcinoma is a rare malignancy, usually found in the salivary glands, although this unusual tumor can be found at other sites of the body. In particular, regarding adenoid cystic carcinoma of the cervix (ACCC) most frequently reports are given for postmenopausal women. In this respect, our work is one among very few in the literature that considers a cytologic picture of this uncommon cervix carcinoma. The case of 74 year old patient with postmenopausal bleeding is described. Both Pap smear and air dried smear of the uterine cervix were analyzed. The cytologic findings revealed very few small clusters of abnormal glandular cells, as well as some amorphous eosinophilic globule-like material, with granulomatous and necrotic background. The latter includes a lot of histiocytes, multinucleated giant cells, large aggregates of epitheloid cells and lymphocytes. Histology revealed the diagnosis of ACCC. We emphasize the importance of careful screening of Pap smear that might be crucial in the case of suspicious clinical findings in postmenopausal women, when the possibility of ACCC has to be considered.

Rectal biopsy was done in 39 follow-up cases of squamous cell carcinoma of cervix treated with radiotherapy who clinically presented as cases of radiation proctitis. On histological examination, definite evidence of radiation injury was found in 23 cases. In rectal mucosa, radiation ulcers, broken epithelial lining, glandular atrophy, inflammatory cell infiltration, and edema of stroma were seen. Muscularis mucosa was either intact or partially broken. In submucosa, blood vessels showed endarteritis, plasma cell infiltration, fibrinoid necrosis, and hyalinization of vessel wall. In a few cases, hyalinization, edema, and vacuolation of muscle fibres were seen in muscle layer. In one case, squamous cell carcinoma of rectum was diagnosed. During follow-up examinations no complication due to rectal biopsy was observed.

Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.

Sarcoidosis is a chronic granulomatous disease that can affect multiple organs. The lungs, eyes, and skin are known to be highly affected organs in sarcoidosis. There have been reports based on random muscle biopsy that 32-80% of systemic sarcoidosis comprises noncaseating granulomas; however, muscle involvement in sarcoidosis is generally asymptomatic and has an unknown frequency. We describe a case of acute to subacute sarcoid myositis of the skeletal and extraocular muscles. Typical ophthalmic involvement (manifested by infiltration of the ocular adnexa, intraocular inflammation, or infiltration of the retrobulbar visual pathways) and extraocular sarcoid myositis (as with the present case) is infrequently reported. It is important to keep in mind the rare yet perhaps underestimated entity of sarcoid myositis, and to utilize muscle biopsy and imaging tests for appropriate diagnosis and management of patients with sarcoidosis.

Uterine epithelial cell proliferation and endometrial hyperplasia: evidence from a mouse model.

In the uterus, epithelial cell proliferation changes during the estrous cycle and pregnancy. Uncontrolled epithelial cell proliferation results in implantation failure and/or cancer development. Transforming growth factor-β (TGF-β) signaling is a fundamental regulator of diverse biological processes and is indispensable for multiple reproductive functions. However, the in vivo role of TGF-β signaling in uterine epithelial cells remains poorly defined. We have shown that in the uterus, conditional deletion of the Type 1 receptor for TGF-β (Tgfbr1) using anti-Müllerian hormone receptor type 2 (Amhr2) Cre leads to myometrial defects. Here, we describe enhanced epithelial cell proliferation by immunostaining of Ki67 in the uteri of these mice. The aberration culminated in endometrial hyperplasia in aged females. To exclude the potential influence of ovarian steroid hormones, the proliferative status of uterine epithelial cells was assessed following ovariectomy. Increased uterine epithelial cell proliferation was also revealed in ovariectomized Tgfbr1 Amhr2-Cre conditional knockout mice. We further demonstrated that transcript levels for fibroblast growth factor 10 (Fgf10) were markedly up-regulated in Tgfbr1 Amhr2-Cre conditional knockout uteri. Consistently, treatment of primary uterine stromal cells with TGF-β1 significantly reduced Fgf10 mRNA expression. Thus, our findings suggest a potential involvement of TGFBR1-mediated signaling in the regulation of uterine epithelial cell proliferation, and provide genetic evidence supporting the role of uterine epithelial cell proliferation in the pathogenesis of endometrial hyperplasia. © The Author 2014.

Using the longitudinal data of the Adult Health Study (AHS) cohort collected during 1958-86, we examined for the first time the relationship between exposure to ionizing radiation and the incidence of 19 selected nonmalignant disorders. Diagnoses of the diseases were based on general laboratory tests, physical examinations, and histories taken during the biennial AHS examinations. The outcomes were encoded as three-digit International Classification of Diseases codes in the AHS data base, which served as the basis for case ascertainment. Statistically significant excess risk was detected for myoma uteri, chronic hepatitis and liver cirrhosis, and thyroid disease, defined broadly as the presence of one or more of certain noncancerous thyroid conditions. The finding for myoma uteri might be additional evidence indicating that benign tumor growths are possible effects of radiation exposure. An age-at-exposure effect was detected in nonmalignant thyroid disease, with increased risk for those exposed at ages ≤ 20 yr, but not for older persons. Thus, the AHS data also suggest that the thyroid gland in young persons is more radiosensitive not only to the development of thyroid malignancies, as shown in the most recent LSS report on cancer incidence, but also possibly to the development of nonmalignant disorders. Our findings hold independent of the dose effects observed for thyroid malignancies. No significant dose-response relationships were detected in any of our cardiovascular disease endpoints. Our analysis also suggests that new occurrences of lens opacity during 1958-86 are not increased with radiation dose among the AHS participants. Our results emphasize the utility and importance of the AHS in searching for the effects of acute exposure to ionizing radiation in noncancer diseases. (J.P.N.)

Full Text Available Abstract Background In the mouse uterus, pregnancy is accompanied by changes in tachykinin and tachykinin receptor gene expression and in the uterotonic effects of endogenous tachykinins. In this study we have investigated whether changes in tachykinin expression and responses are a result of changes in ovarian steroid levels. Methods We quantified the mRNAs of tachykinins and tachykinin receptors in uteri from ovariectomized mice and studied their regulation in response to estrogen and progesterone using real-time quantitative RT-PCR. Early (3 h and late (24 h responses to estrogen were evaluated and the participation of the estrogen receptors (ER, ERalpha and ERbeta, was analyzed by treating mice with propylpyrazole triol, a selective ERalpha agonist, or diarylpropionitrile, a selective agonist of ERbeta. Results All genes encoding tachykinins (Tac1, Tac2 and Tac4 and tachykinin receptors (Tacr1, Tacr2 and Tacr3 were expressed in uteri from ovariectomized mice. Estrogen increased Tac1 and Tacr1 mRNA after 3 h and decreased Tac1 and Tac4 expression after 24 h. Tac2 and Tacr3 mRNA levels were decreased by estrogen at both 3 and 24 h. Most effects of estrogen were also observed in animals treated with propylpyrazole triol. Progesterone treatment increased the levels of Tac2. Conclusion These results show that the expression of tachykinins and their receptors in the mouse uterus is tightly and differentially regulated by ovarian steroids. Estrogen effects are mainly mediated by ERalpha supporting an essential role for this estrogen receptor in the regulation of the tachykinergic system in the mouse uterus.

Intrauterine adhesion (IUA) is a common uterine cavity disease characterized by the unsatisfactory regeneration of damaged endometria. Recently, stem cell transplantation has been proposed to promote the recovery process. Here we investigated whether human amniotic mesenchymal stromal cells (hAMSCs), a valuable resource for transplantation therapy, could improve endometrial regeneration in rodent IUA models. Forty female Sprague-Dawley rats were randomly assigned to five groups: normal, sham-operated, mechanical injury, hAMSC transplantation, and negative control group. One week after intervention and transplantation, histological analyses were performed, and immunofluorescent and immunohistochemical expression of cell-specific markers and messenger RNA expression of cytokines were measured. Thicker endometria, increased gland numbers and fewer fibrotic areas were found in the hAMSC transplantation group compared with the mechanical injury group. Engraftment of hAMSCs was detected by the presence of anti-human nuclear antigen-positive cells in the endometrial glands of the transplantation uteri. Transplantation of hAMSCs significantly decreased messenger RNA levels of pro-inflammatory cytokines (tumor necrosis factor-α and interleukin-1β), and increased those of anti-inflammatory cytokines (basic fibroblast growth factor, and interleukin-6) compared with the injured uterine horns. Immunohistochemical expression of endometrial epithelial cells was revealed in specimens after hAMSC transplantation, whereas it was absent in the mechanically injured uteri. hAMSC transplantation promotes endometrial regeneration after injury in IUA rat models, possibly due to immunomodulatory properties. These cells provide a more easily accessible source of stem cells for future research into the impact of cell transplantation on damaged endometria.

Primary primitive neuroectodermal tumors (PNETs) are rare and high-grade malignant tumors that mostly occur in children and young adults. The most common sites are the trunk, limbs, and retroperitoneum. Herein, we present a case of a PNET involving the cervix uteri in a 27-year-old woman. The lesion showed characteristic histologic features of a PNET and was positive for the immunohistochemical markers cluster of differentiation (CD) 99, vimentin, neuron-specific enolase, neural cell adhesion molecule 1 (CD56), and CD117 (c-kit), further defining the tumor while helping to confirm PNET. The clinical Stage IIIB tumor was treated with chemotherapy and radiotherapy. PMID:23836982

Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

Thickened uterine endometrium with abnormal uterine bleeding highly suggests endometrial hyperplasia or endometrial carcinoma. A case of 35-year-old nulliparous woman came to our department with endometrial mass manifesting as endometrial cancer. Transrectal ultrasonography and magnetic resonance imaging (MRI) showed an 8x6 cm multicystic, ill-defined mass compacted at the uterine endometrium, the anterior wall of the uterus, and 3x3 cm heterogenous mass at the left adnexa. The edometrial mass showed multiple septations with enhancement and low-signal intensity on T2-weighted images. After endometrial biopsy was done and simple hyperplasia without atypia was observed at the histopathologic finding, the patient underwent robot-assisted laparoscopy and diagnosed as adenomyoma at the frozen pathology. After adenomyomectomy, permanent pathologic analysis revealed the same result and she recovered without any complications and responded well to gonadotropin-releasing hormone (GnRH) agonist therapy.

Full Text Available Malignant transformation of endometriosis has been extensively described in the literature. However, extragonadal endometrioid adenocarcinoma, either de novo or arising from malignant transformation of endometriosis, is rare. The present case report describes a patient with endometrioid adenocarcinoma on the serous surface of the small intestine. A 25- year-old female with no history of endometriosis was referred to our hospital with an intrapelvic tumor. An internal examination, ultrasound, and magnetic resonance imaging revealed a round mass approximately 80 mm in diameter; however, identification of the affected organ was difficult. Because we could not rule out malignancy based on the non-specific radiologic findings, laparotomy was performed. A mass with ileal adhesions was detected intraoperatively. In addition, the uterus and bilateral adnexa appeared normal. The tumor was resected with part of the ileum. Histopathology confirmed a diagnosis of endometrioid adenocarcinoma originating from the serous surface of the small intestine.

Leprosy is a chronic granulomatous disease caused by the bacillus Mycobacterium leprae. It primarily affects the skin and peripheral nerves and is still endemic in various regions of the world. Clinical presentation depends on the patient's immune status at the time of infection and during the course of the disease. Leprosy is associated with disability and marginalization. Diagnosis is clinical and is made when the patient has at least 1 of the following cardinal signs specified by the World Health Organization: hypopigmented or erythematous macules with sensory loss; thickened peripheral nerves; or positive acid-fast skin smear or skin biopsy with loss of adnexa at affected sites. Leprosy is treated with a multidrug combination of rifampicin, clofazimine, and dapsone. Two main regimens are used depending on whether the patient has paucibacillary or multibacillary disease.

Full Text Available A post menopausal lady presented with lump lower abdomen and bleeding per vaginum. USG revealed diffuse enlargement of the uterus. On hysterectomy, a grossly enlarged uterus with cystic left ovary were found. Hysterectomy was done and uterus with bilateral adnexa submitted for histopathological examination. Microscopic examination of the body of uterus revealed sheets of small lymphoid cells were found to replace the endo- and myo-metrium. These cells have small nuclei with clumped chromatin, and no prominence of nucleoli. They are not forming lymphoid follicles or germinal centers. Similar lymphoid cells were also found in the left ovary admixed with ovarian stroma. On IHC these cells were found to be CD45, CD20, CD23 positive, and negative for CD3 , CK and SMA. The case is diagnosed as a primary small lymphocytic lymphoma of uterus with left ovarian spread.

Full Text Available Background. Complete androgen insensitivity syndrome is a rare syndrome in which the uterus is absent and testes rather than ovaries are present. Patients usually visit a gynecologist due to primary amenorrhea. Case. A forty-eight-year-old woman with lower abdominal pain and anamnesis of uterus agenesis was operated on due to bilateral cystic masses. A 5 × 3 × 1.2 cm left adnexal cyst revealed the presence of a serous cyst with a hypoplastic ductus deferens. A smaller cyst of the right adnexa revealed immature testis tissue with Leydig-cell hyperplasia. After karyotype and hormonal examinations, laparoscopic gonadectomy was performed. Conclusion. Attention should be paid in all cyst-removing operations in cases of uterus agenesis, due to the high incidence of malignancy. Not of less importance is the issue of informing the patient in the most appropriate way.

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Introduction: Cervical cancer can be successfully prevented by effective treatment. Aim: Analyse of success of cryotherapy in LSIL and ASCUS. Materials et methods: In retrospective study between January 2016 to March 2017, 3244 PAP test were analysed. 257 patients who had been diagnosed with LSIL and ASCUS from PAP smear were divided in two groups: women who had HPV positive, colposcopic positive and cytologic finding of LSIL or ASCUS treathed with cryotherapy and women with LSIL, ASCUS and negative colposcopy. χ2 test was used for statistical analysis of data. Results: Analysis of 3244 PAP smears showed negative for intraepithelial lesion or malignancy (NILM) in 90,10% (N-2923), and abnormal in 9,8% (N-321) of women. ASCUS was found in 4,8% (N-156) and ASC-H in 0,2% (N-6), LSIL in 3,1% (N-101), HSIL in 0,64% (N-21). The average age of patients with ASCUS lesion was 41 ± 12 years. After cryotherapy, HSIL had progression in 1,5% (N-1), persistence in 6,3% (N-4) and regression in 91,7% (N-58). Progression occured in 10,5% (N-4) of HSIL, persistence in 52,6% (N-20) and regression in 36,7% (N-14) in 38 women with LSIL lesion after repeated PAP test. Progression occured in 8% (N-10) of LSIL and 4% HSIL (N-5), persistence in 58% (N-72) and regression in 29,8% (N-37) in 124 women with ASCUS lesion after treatment and repeated PAP test. Difference in progression lesions in HSIL between women with cryotherapy (1,5%) and follow-up (10,5%) after LSIL is not significant, but progression to CIN II occured after cryotherapy. CIN III or cervical cancer was not found. Conclusion: Cryotherapy prevents progression of LSIL in HSIL and in cervical cancer. Because of that cryotherapy is successful method in prevention of cervical cancer. PMID:28974850

Cervical cancer can be successfully prevented by effective treatment. Analyse of success of cryotherapy in LSIL and ASCUS. In retrospective study between January 2016 to March 2017, 3244 PAP test were analysed. 257 patients who had been diagnosed with LSIL and ASCUS from PAP smear were divided in two groups: women who had HPV positive, colposcopic positive and cytologic finding of LSIL or ASCUS treathed with cryotherapy and women with LSIL, ASCUS and negative colposcopy. χ 2 test was used for statistical analysis of data. Analysis of 3244 PAP smears showed negative for intraepithelial lesion or malignancy (NILM) in 90,10% (N-2923), and abnormal in 9,8% (N-321) of women. ASCUS was found in 4,8% (N-156) and ASC-H in 0,2% (N-6), LSIL in 3,1% (N-101), HSIL in 0,64% (N-21). The average age of patients with ASCUS lesion was 41 ± 12 years.

There is a controversy regarding the effects of the analogues of the gonadotrophin-releasing hormone (GnRH) in radiotherapy. This has led us to study the possible radio-protection of the ovarian function of a GnRH agonist analogue (GnRHa), triptorelin, in adult, female rats (Rattus norvegicus sp.). The effects of the X-irradiation on the oocytes of ovarian primordial follicles, with and without GnRHa treatment, were compared, directly in the female rats (F 0 ) with reproductive parameters, and in the somatic cells of the resulting foetuses (F 1 ) with cytogenetical parameters. In order to do this, the ovaries and uteri from 82 females were extracted for the reproductive analysis and 236 foetuses were obtained for cytogenetical analysis. The cytogenetical study was based on the data from 22,151 metaphases analysed. The cytogenetical parameters analysed to assess the existence of chromosomal instability were the number of aberrant metaphases (2234) and the number (2854) and type of structural chromosomal aberrations, including gaps and breaks. Concerning the reproductive analysis of the ovaries and the uteri, the parameters analysed were the number of corpora lutea, implantations, implantation losses and foetuses. Triptorelin confers radio-protection of the ovaries in front of chromosomal instability, which is different, with respect to the single and fractioned dose. The cytogenetical analysis shows a general decrease in most of the parameters of the triptorelin-treated groups, with respect to their controls, and some of these differences were considered to be statistically significant. The reproductive analysis indicates that there is also radio-protection by the agonist, although minor to the cytogenetical one. Only some of the analysed parameters show a statistically significant decrease in the triptorelin-treated groups.

Premenopausal women undergoing adjuvant chemotherapy and/or radiotherapy for Breast Cancer (BC) treatment have significant bone loss. This high bone mineral density loss can lead to an increased risk of fractures. In this study, there were evaluated parameters involved in osteoporosis when rats were subjected to a chemotherapy regimen (TC) and/or irradiation (IR). Female Wistar rats were divided into 3 groups: control (G1), TC+IR (G2) and IR (G3). The animals were euthanized after 5 months at the end of treatment and their femurs were excised and dissected. Sections of 10 μm thick were used for μXRF analysis at the National Laboratory of Synchrotron Light. The uteri of these rats were collected and weighed. The obtained results showed that animals from G2 had a significant reduction (p<0.05) of uterine mass when compared to control. The qualitative analysis performed by μXRF showed that animals from G2 had iron in bone composition of the femurs. This same result was notobserved in animals from G1 and G3 groups. These results suggest that early menopause occurs and osteoporosis begins, probably because of the absence, or reduced, production of estrogen. The presence of iron in the G2 samples in indicates the process of osteoporosis, because according to literature, this ion is competitive with calcium ions. - Highlights: • Premenopausal women undergoing Breast Cancer treatment have significant bone mineral density loss. • Animals submitted to Breast Cancer treatment have their uteri mass decreased. • The µXRF can detect differences in Iron concentration patterns between rats treated, and not treated, with chemotherapy. • Breast Cancer treatment changes the concentration of estrogens, increasing the chances of developing osteoporosis

Twenty-two patients had been using Mirena® for 5 years but had not been submitted to endometrial resection prior to insertion of the device. Twenty-four patients were submitted to endometrial resection at the time of Mirena® insertion. The remaining 43 patients with adenomyosis had undergone no previous hormonal treatment and served as a control group. Cox-2 and aromatase expression were determined in the endometrium by immunohistochemistry.Results: Use of Mirena® for 5 years reduced aromatase expression in the endometrium; however, this reduction was significantly greater in the uteri previously submitted to endometrial resection. The reduction in Cox-2 expression was significant only in the uteri submitted to endometrial resection followed by the insertion of Mirena®.Conclusion: Endometrial resection followed by the insertion of Mirena® was associated with greater rates of amenorrhea in patients with adenomyosis, which in turn were associated with a more effective inhibition of aromatase and Cox-2 expression in the endometrium.Keywords: aromatase, Mirena®, adenomyosis, Cox-2, endometrium, levonorgestrel

Prostaglandins (PGs) are important regulators of reproductive processes including early embryonic development. We analyzed the most relevant PG in bovine uteri at different preimplantation pregnancy stages when compared with non-pregnant controls. Additionally, endometrium and trophoblast tissues were examined regarding specific enzymes and receptors involved in PG generation and function. Simmental heifers were artificially inseminated or received seminal plasma only. At days 12, 15, or 18, post-estrus uteri were flushed for PG determination by liquid chromatography-tandem mass spectrometry. Endometrium and trophoblast tissues were sampled for RNA extraction and quantitative real-time PCR analysis. At all days and points of time examined, the concentration of 6-keto PGF(1alpha) (stable metabolite of PGI(2)) was predominant followed by PGF(2alpha)>PGE(2)>PGD(2) approximately TXB(2) (stable metabolite of TXA(2)). At days 15 and 18, PG increased from overall low levels at day 12, with a much more pronounced increase during pregnancy. The PGF(2alpha)/PGE(2) ratio was not influenced by status. The highest PG concentration was measured at day 15 with 6-keto PGF(1alpha) (6.4 ng/ml) followed by PGF(2alpha) (1.1 ng/ml) and PGE(2) (0.3 ng/ml). Minor changes in endometrial PG biosynthesis enzymes occurred due to pregnancy. Trophoblasts revealed high transcript abundance of general and specific PG synthases contributing to uterine PG. As PGI(2) and PGF(2alpha) receptors were abundantly expressed by the trophoblast, abundant amounts of PGI(2) and PGF(2alpha) in the uterine lumen point towards an essential role of PG for the developing embryo. High amounts of PG other than PGE(2) in the preimplantation uterus may be essential rather than detrimental for successful reproduction.

Full Text Available The use of a combined therapy with low doses of estrogens plus antidepressants to treat depression associated to perimenopause could be advantageous. However the use of these combinations is controversial due to several factors, including the time of intervention in relation to menopause onset. This paper analyzes whether time post-OVX influences the antidepressant-like action of a combination of ethynyl-estradiol (EE2 and citalopram (CIT in the forced swim test (FST. Middle-aged (15 months old female Wistar rats were ovariectomized and after one or three weeks treated with EE2 (1.25, 2.5 or 5.0 µg/rat, s.c.; −48 h or CIT (1.25, 2.5, 5.0 or 10 mg/kg, i.p./3 injections in 24 h and tested in the FST. In a second experiment, after one or three weeks of OVX, rats received a combination of an ineffective dose of EE2 (1.25 µg/rat, s.c., −48 h plus CIT (2.5 mg/kg, i.p./3 injections in 24 h and subjected to the FST. Finally, the uteri were removed and weighted to obtain an index of the peripheral effects of EE2 administration. EE2 (2.5 or 5.0 µg/rat reduced immobility after one but not three weeks of OVX. In contrast, no CIT dose reduced immobility at one or three weeks after OVX. When EE2 (1.25 µg/rat was combined with CIT (2.5 mg/kg an antidepressant-like effect was observed at one but not three weeks post-OVX. The weight of the uteri augmented when EE2 was administrated three weeks after OVX. The data suggest that the time post-OVX is a crucial factor that contributes to observe the antidepressant-like effect of EE2 alone or in combination with CIT.

The right uterine horn of alpacas causes luteolysis in the right ovary, whereas the left horn causes luteolysis in both ovaries. Female reproductive tracts were studied in 32 adult llamas, 12 adult alpacas, and 21 mid-gestation female fetuses to determine if there is a dichotomy in the vascular anatomy between the 2 sides. Adult tracts were studied by either injection of colored latex into the veins and arteries followed by tissue clearing or by injection of colored fluids during transillumination. Fetal uteri were studied by transillumination. The angioarchitecture of the ovarian vascular pedicle was similar to that reported for ewes. There was no vessel comparable to the middle uterine artery, which is the largest uterine artery in the other farm species. A striking difference from the uterine vascular of other farm species was the presence of a major branch of the right uterine artery that crossed the cranial intercornual area to supply much of the left uterine horn. A corresponding major vein originated from the left horn, crossed the mid-line, and terminated as a branch of the right uterine vein. Thus, the vascular anatomy indicated that much venous blood from the left horn drained to the right side. This was confirmed by injection of colored fluid into a small venous branch at the tip of the left horn. The prominent cross-over vessels were observed in the fetal uteri, and the diameter of the left uterine fetal horn (6.7 +/- 0.6 mm) was greater (P blood from the left horn into an artery supplying the right ovary was not defined in this study. However, the results provide an anatomical basis for functional testing of the cross-over hypothesis and defining the area of venoarterial transfer in camelids.

The study uniquely described the clinical value of transabdominal ultrasonography for monitoring features characterizing the estrous cycle in female cheetahs (Acinonyx jubatus). The reproductive tracts of 21 female, nulliparous, and relatively aged (median: 11 and interquartile range: 9.25-14 years) captive cheetahs resident on two sites in Namibia were assessed by transabdominal ultrasound. Subsequently, the ovarian findings on ultrasound were compared with direct visualization while performing laparoscopic sterilization. A combination of these observations supported by concurrent sampling for vaginal cytology and serum progesterone concentrations defined the estrous status of individual animals. At one site, six cheetahs had been implanted with the GnRH agonist, deslorelin as a contraceptive at least once within the preceding 11 years. On ultrasound, 31 uterine horns and 35 ovaries with discernible structures on 28 (86%) were visualized in the 21 cheetahs. The uterine body was difficult to visualize because of its intrapelvic location. Eleven of 19 uteri (58%) visualized showed endometrial edema suggestive of estrogenization. The uteri of four cheetahs (19%) showed evidence of mild cystic endometrial hyperplasia. Paraovarian cysts were seen on ultrasound (n = 21) and laparoscopy (n = 26) in 16 (76.2%) and 18 (85.7%) cheetahs, respectively. Ovarian volumes obtained from ultrasonographically determined dimensions predicted cyclic activity. Laparoscopy showed that 19 ovaries had discernible follicular structures. In the study population, 10 (47.6%) cheetahs were in proestrus or estrus; none in the luteal phase; and 11 (52.4%) in anestrus. Transabdominal ultrasound, in combination with serum progesterone concentrations and vaginal cytology, was used with acceptable accuracy to assess cyclic ovarian activity in captive cheetahs. A considerable proportion of this aged population showed ovarian activity and the prevalence of paraovarian cysts was notable. A

Full Text Available Abstract Background Estrogen or phytoestrogens treatment has been suggested to improve cognitive function of the brain in postmenopausal women. However, there is lack of information on the mechanism of such treatment on the central nervous system. The present study aimed to determine the effects of estradiol and soy germ phytoestrogens on spatial memory performance in ovariectomized rats and to explore the underlying mechanisms affecting the central nervous system. Methods Ovariectomized Sprague-Dawley rats were fed a basic diet supplemented with soy germ phytoestrogens (0.4 g/kg or 1.6 g/kg or 17β-estradiol (0.15 g/kg for 12 weeks. At the end of the experiment, animals were evaluated for their spatial learning and memory performance by the Morris Water Maze task. The expressions of brain-derived neurotrophic factor (BDNF and synaptic formation proteins in the hippocampal tissue were estimated using RT-PCR and ELISA. Results It was found that rats supplemented with soy germ phytoestrogens or estradiol performed significantly better in spatial memory acquisition and retention when compared to the rats fed on the control diet. Estradiol or the high dose of phytoestrogens treatment significantly increased BDNF concentration and the mRNA levels for BDNF and its TrkB receptors as well as the synaptic formation proteins, synaptophysin, spinophilin, synapsin 1 and PSD-95, in the hippocampal tissue of the experimental animals. It was also found that phytoestrogens, in contrast to estradiol, did not show any significant effect on the vaginal and uteri. Conclusion Soy germ phytoestrogens, which may be a substitute of estradiol, improved spatial memory performance in ovariectomized rats without significant side-effects on the vaginal and uteri. The memory enhancement effect may relate to the increase in BDNF and the synaptic formation proteins expression in the hippocampus of the brain.

A clearcut definition of the transition from the cervix to the lower uterine segment is lacking. We therefore evaluated the location of the anatomic border between the cervix and the uterine corpus. Using both morphometry and immunohistochemisty, we examined the epithelial and stromal cell types in this transition zone. In 26 patients, longitudinal sections from the cervix uteri up to the fundus uteri were paraffin embedded and immunohistochemically stained for BCL2, keratin 5, Ki-67, CD10, and CD34. Examination of the slides resulted in the identification of a junctional zone in the cranial portion of the cervix, which is characterized by a usually abrupt morphologic and immunohistochemical transition from an endocervical-type mucinous epithelium to a ciliated tubal-like epithelium and a slow transition in stromal marker expression patterns. This epithelial transition was characterized by its intense keratin 5 and BCL2 staining with accompanying Ki-67 expression in the tubal-like epithelium, whereas the endocervical epithelium was largely negative for these markers. CD10 expression was usually quite intense directly around endocervical invaginations, but the remaining stroma was negative. Toward the endometrial cavity, expression increased and endometrial stroma displayed full thickness expression for CD10. CD34 showed a reverse pattern to CD10, with moderate expression in the endocervical stroma, which disappeared in the endometrial stoma. The immunohistochemical identification of this transition may allow a more objective determination of the extension of endometrial carcinoma into the cervix in cases that are morphologically problematic. Furthermore, as ciliated tubal-like epithelium is invariably found cranial to the uterine-cervix-isthmus junction, a diagnosis of tubal metaplasia should not be made in this region and tubal-like epithelium is not indicative of a metaplastic process.

Triazines are herbicides that are widely used worldwide, and we previously observed that the maternal exposure of mice to simazine (50 or 500 μg/kg) resulted in smaller ovaries and uteri of their female offspring. Here, we investigated the underlying mechanism that may account for the reproductive dysfunction induced by simazine. We found that following maternal exposure, simazine is transmitted to the offspring, as evidenced by its presence in the offspring ovaries. Analyses of the simazine-exposed offspring revealed that the expression of the relaxin hormone receptor, relaxin-family peptide receptor 1 (RXFP1), prominently decreased in their ovaries and uteri. In addition, downstream target genes of the relaxin pathway including nitric oxide (NO) synthase 2 (Nos2), Nos3, matrix metallopeptidase 9 (Mmp9), and vascular endothelial growth factor (Vegf) were downregulated in their ovaries. Moreover, AKT and extracellular signal-regulated kinases (ERK) levels and their phosphorylated active forms decreased in simazine-exposed ovaries. In vitro exposure of the human ovarian granulosa cells (KGN) and uterine endometrium cells (Hec-1A) to very low concentrations (0.001 to 1 nM) of triazines including atrazine, terbuthylazine, and propazine repressed NO production with a concurrent reduction in RXFP1, NOS2, and NOS3. The inhibitory action of triazines on NO release was dependent on RXFP1, phosphoinositol 3-kinase (PI3K)/AKT, and ERK. Radioligand-binding assay also confirmed that triazines competitively inhibited the binding of relaxin to its receptor. Therefore, the present study suggests that triazine herbicides act as endocrine disrupters by interfering with relaxin hormone signaling. Thus, further evaluation of their impact on human health is imperative. - Highlights: • Triazines downregulate critical molecules involved in the relaxin signaling pathway. • Triazines act as potent antagonists of binding of relaxin to its receptor. • Triazines disrupt nitric oxide

Full Text Available OBJECTIVES: Genistein is known to influence reproductive system development through its binding affinity for estrogen receptors. The present study aimed to further explore the effect of Genistein on the development of the reproductive system of experimental rats. METHODS: Eighteen post-weaning female Sprague Dawley rats were divided into the following groups: (i a control group that received vehicle (distilled water and Tween 80; (ii a group treated with 10 mg/kg body weight (BW of Genistein (Gen 10; and (iii a group treated with a higher dose of Genistein (Gen 100. The rats were treated daily for three weeks from postnatal day 22 (P22 to P42. After the animals were sacrificed, blood samples were collected, and the uteri and ovaries were harvested and subjected to light microscopy and immunohistochemical study. RESULTS: A reduction of the mean weekly BW gain and organ weights (uteri and ovaries were observed in the Gen 10 group compared to the control group; these findings were reversed in the Gen 100 group. Follicle stimulating hormone and estrogen levels were increased in the Gen 10 group and reduced in the Gen 100 group. Luteinizing hormone was reduced in both groups of Genistein-treated animals, and there was a significant difference between the Gen 10 and control groups (p<0.05. These findings were consistent with increased atretic follicular count, a decreased number of corpus luteum and down-regulation of estrogen receptors-a in the uterine tissues of the Genistein-treated animals compared to the control animals. CONCLUSION: Post-weaning exposure to Genistein could affect the development of the reproductive system of ovarian-intact experimental rats because of its action on the hypothalamic-pituitary-gonadal axis by regulating hormones and estrogen receptors.

Combined persistent mullerian duct syndrome, transverse testicular ectopia and mosaic klinefelter's syndrome

Persistent Mullerian Duct Syndrome (PMDS), a rare form of male pseudohermaphroditism, is characterized by the persistence of Mullerian duct structures (uterus, fallopian tubes and upper two-thirds of vagina) in otherwise normallyvirilized males (Karyotype 46XY). Patients suffering from PMDS present with cryptorchidism, inguinal hernia and infertility. Diagnosis is established when Mullerian duct structures are discovered either during ultrasonography for localization of undescended testis(s), during surgical exploration for cryptorchidism or herniorrhaphy (hernii uteri inguinalis). Presence of both testes on one side of the scrotum is known as Transverse Testicular Ectopia (TTE). Co-existence of PMDS and transverse testicular ectopia in a patient of mosaic Klinefelter's syndrome (Karyotype 46XY/47XXY) is a unique genetic association. (author)

Placenta percreta is an obstetric condition in which the placenta invades through the myometrium. This is the most severe form of placenta accreta and may result in spontaneous uterine rupture, a rare complication that threatens the life of both mother and fetus. In this case report, we describe a 32-year-old woman in her fourth pregnancy, diagnosed with repeated placenta accreta, which was eventually complicated by spontaneous uterine rupture at 24 weeks’ gestation. This patient had a history of abnormal placentation in prior pregnancies and previous uterine injuries. This case demonstrates a pattern of escalating placental invasiveness, and raises questions regarding the process of abnormal placentation and the manifestation of uterine rupture in scarred uteri.

Abstract Objective: Using endometrial secretion analysis, we assessed whether altered inflammatory cytokine levels can be detected in the uterine environment in asthma patients, thereby providing a possible cause of reduced fertility in asthmatics. Methods: Forty-four unexplained infertile women...... no effect on VEGF levels in uteri. Serum high sensitivity CRP was negatively correlated with VEGF in endometrial secretions. No other significant correlations were observed between peripheral blood values and markers found in utero. Conclusion: Asthma is associated with lower values of VEGF in uterine...... endometrial secretions, which might affect the receptiveness of the endometrium and thereby increase time to pregnancy. The effect appears to be associated with non-atopic asthma with general increased systemic inflammation....

Acute dacryocystitis: another clinical manifestation of sporotrichosis

Full Text Available Sporotrichosis associated with exposure to domestic cats is hyperendemic in Rio de Janeiro, Brazil. A review of the clinical records at our institute revealed four patients with clinical signs of dacryocystitis and a positive conjunctival culture for Sporothrix who were diagnosed with Sporothrix dacryocystitis. Three patients were children (< 13 years of age and one patient was an adult. Two patients reported contact with a cat that had sporotrichosis. Dacryocystitis was associated with nodular, ulcerated lesions on the face of one patient and with granulomatous conjunctivitis in two patients; however, this condition manifested as an isolated disease in another patient. All of the patients were cured of the fungal infections, but three patients had chronic dacryocystitis and one patient developed a cutaneous fistula. Sporotrichosis is usually a benign disease, but may cause severe complications when the eye and the adnexa are affected. Physicians, especially ophthalmologists in endemic areas, should be aware of the ophthalmological manifestations and complications of sporotrichosis.

Full Text Available Thelaziasis is an Arthropod-born disease of the eye and adnexa caused by Thelazia callipaeda, a nematode parasite transmitted by drosophilid flies to carnivores and humans. Because of its distribution mainly confined to South Asian countries and Russia, it is commonly known as Oriental Eye worm. It is often under-reported and not been given its due clinical importance. We report first case of human Thelaziasis from Hassan District, Karnataka. Five creamy-white, translucent worms were removed from the conjunctival sac of a 74-year-old male patient. Based on morphological characters, the worms were identified as nematodes belonging to the genus Thelazia and speciation was confirmed by CDC, Atlanta as callipaeda. Rarity of the disease and its ability to cause both extra and intraocular manifestations leading to ocular morbidity is the reason for presenting this case. From the available data, this is the first case report from Karnataka, India.

Biopsy is the technique of choice for the definitive diagnosis of endometrial carcinoma. Since lymphatic tumor spread has been demonstrated to depend on the degree of myometrial involvement, the definition of the latter with imaging techniques may significantly affect both pfognosis and therapy. We investigated, by means of MR imaging at 0.5 T, 14 patients with endometrial carcinoma, to assess both tumor stage and myometrial involvement. FIGO staging system was employed, and M parameter evaluated (M0= no myometrial involvement; M1involvement confined to the inner third; M2= Involvement confined to the middle third; M3= involvement of the whole myometrium). Another parameter was the characteristic high signal of the tumor on PD and T2W images. The patients were then operated and MR information was correlated with surgical findings. Overall diagnostic accuracy of MR imaging was 85.7% in tumor staging, and 92.2% in defining M parameter. Tumor spread into adnexa and into cervical canal was poorly demonstrated by MR imaging

Liu, Y; Hui, N

1994-04-01

From September 1992 to September 1993, 150 patients aged 15-68 years underwent laparoscopic gynecologic surgery. These patients included 63 patients with acute abdominal diseases (46 had ectopic pregnancy, 9 rupture of ovary, and 8 torsion of ovarian cyst), which consisted of 90% of total patients with acute abdomen in corresponding period, 63 patients with mass of adnexa, which made up 72% of total patients with ovarian tumors, and 24 patients with uterine diseases. We successfully performed laparoscopic salpingostomy, fallotomy, removal of ovarian cyst, oophorosalpingectomy, myomectomy and laparoscopy assisted vaginal hysterectomy (LAVH) with 2-4 puncture technic after general anesthesia. The largest ovarian tumor and the enlarged uterus were 14 and 16 cm in diameter respectively. Four patients had laparotomy because of severe pelvic adhesions and the laparotomy rate was about 2.6%. The procedure lasted 20-240 minutes and bleeding was less than 200ml. No major surgical complication was encountered.

Trichilemmal carcinoma (TC) is described as a very rare cancer of the skin adnexa. 1 2 Ninety per cent of the lesions present on the scalp. Prognostic factors in TC are limited to lymph node status and surgical margins, with no statistical significance observed for age or gender of the patient, size of tumour or locoregional recurrence. We present a 46-year-old black patient who developed TC during treatment for breast cancer. Postoperative histology of the scalp lesion excision confirmed no involved margins. At the three monthly appointment, the patient was reviewed and multiple, new scalp lesions were noted. A CT scan of the head, neck found multiple lesions on the scalp, limited to the soft tissue, not involving the outer table of the skull. There was bilateral invasion of the parotid glands. To the best of our knowledge, no syndromes or associations between breast cancer and adnexal skin tumours exist. 2016 BMJ Publishing Group Ltd.

2014-07-01

Torsion of uterine adnexa is an important cause of acute abdominal pain in females. The main organ which can cause torsion is the ovaries, but torsions of the fallopian tube, subserosal myoma, paratubal cyst, and even the uterine body have been reported. The incidence of isolated fallopian tubal torsion is very rare. Even more rarely, it can coil around nearby organs such as the utero-ovarian ligament, showing similar clinical manifestations with those of adnexal torsion. We experienced an extremely rare case of acute abdomen induced by ovarian congestion triggered by the fallopian tube accompanying a paratubal cyst coiling around the utero-ovarian ligament. The right paratubal cyst was misinterpreted as being part of a cystic component of the left ovary on preoperative sonographic examination, and the coiling of the right fallopian tube accompanying the paratubal cyst was misdiagnosed as torsion of the right ovary. We report this rare case with a brief literature review.

Santos, D.R.; Marziona, F.; Oyafuso, M.; Carvalho, M.I. de

1989-01-01

Cervico vaginal smears of women with uterine carcinoma treated with radiotherapy are analyzed in the present work. A series of such smears showed morphological changes suggestive of Chlamydia infection with the Papanicolaou stain. Confirmation of the presence of such agent was done using an avidin-biotin peroxidase technique. A higher prevalence of Chlamydia in the group of patients with carcinoma of the uterus treated with irradiation than in the population without ionizing treatment was verified. The presence of cells with radiotherapic changes infected by Chlamydia is a new finding in cytology. (author)

To study diagnostic and therapeutic strategies, outcomes, and follow-up in a large series of women with adenocarcinoma in situ (AIS) of the uterine cervix and investigate if human papillomavirus (HPV) typing among women with negative cytology reports would have helped with early AIS detection. Records of 132 AIS cases diagnosed between 1989 and 2012 were retrieved. Clinical and pathological data were reviewed and analyzed. Mean age at diagnosis was 37 years. Seventy-two percent (n = 95) of all patients were asymptomatic; diagnosis was established using cytology and biopsy. Primary treatment for 124 patents was cold knife cone or loop electrosurgical excision procedure (LEEP). Positive margins were found in 18% of those women treated with CKC versus 40% in those treated with LEEP. The mean follow-up time was 62 months (range, 2-217 months; median, 46 months). Three recurrences were found after conservative treatment in 86 patients. High-risk HPV (hrHPV) positivity was detected in 115 (96%) of 120 patients, with HPV-18 being the most commonly occurring subtype (51%). There is a small risk of relapse after conservative therapy with cold knife cone or LEEP when resection margins are negative in women with AIS. Patients should be given the options of hysterectomy or conservative therapy with strict follow-up.

Comparison of Dolphins' Body and Brain Measurements with Four Other Groups of Cetaceans Reveals Great Diversity.

2016-01-01

We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our data set ranged in body mass from about 40 to 6,750 kg and in brain mass from 0.4 to 9.3 kg. Dolphin body length ranged from 1.3 to 7.6 m. In our combined data set from the 4 other groups of cetaceans, body mass ranged from about 20 to 120,000 kg and brain mass from about 0.2 to 9.2 kg, while body length varied from 1.21 to 26.8 m. Not all cetaceans have large brains relative to their body size. A few dolphins near human body size have human-sized brains. On the other hand, the absolute brain mass of some other cetaceans is only one-sixth as large. We found that brain volume relative to body mass decreases from Delphinidae to a group of Phocoenidae and Monodontidae, to a group of other odontocetes, to Balaenopteroidea, and finally to Balaenidae. We also found the same general trend when we compared brain volume relative to body length, except that the Delphinidae and Phocoenidae-Monodontidae groups do not differ significantly. The Balaenidae have the smallest relative brain mass and the lowest cerebral cortex surface area. Brain parts also vary. Relative to body mass and to body length, dolphins also have the largest cerebellums. Cortex surface area is isometric with brain size when we exclude the Balaenidae. Our data show that the brains of Balaenidae are less convoluted than those of the other cetaceans measured. Large vascular networks inside the cranial vault may help to maintain brain temperature, and these nonbrain tissues increase in volume with body mass and with body length ranging from 8 to 65% of the endocranial volume. Because endocranial vascular networks and other adnexa, such as the tentorium cerebelli, vary so much in different species, brain size measures from endocasts of some extinct cetaceans may be overestimates. Our regression of body length on endocranial

Spectrum of rectal radiation lesions in cases of cancer cervix

International Nuclear Information System (INIS)

Srivastava, V.K.; Rohatgi, V.K.; Gupta, J.C.

1978-01-01

The study was carried out in 70 cases of carcinoma cervix uteri, showing varying degree of proctitis following radiotherapy treatment for cervical cancer. Grossly, the rectal mucosa showed oedema, congestion, granular proctitis, ulceration, and microscopically stromal connective tissue as well as epithelial changes. The stromal changes have been emphasised as useful diagnostic criteria of radiation reaction. The familarity of these changes is considered necessary because it is imperative to know categorically that a given lesion is entirely or in part due to radiation or due to extension of adjacent tumour in the cervix. Further, this issue is very important in management of cases of cancer cervix. The criteria of distinguishing the lesions in the rectal tissue have been laid down. (auth.)

An increase in breast cancer and tumors of reproductive organs was revealed both in a group of women from the regions which are subject to radiation control after the Chernobyl NPP accident and a wider group of Ukrainian female population non-restricted to the above region. Geographical distribution of morbidity is demonstrated. Both genetic and environmental factors are proved to play a part in the susceptibility to development of breast and corpus uteri cancers. The contribution of each of the above factors is assessed.Chromosomal instability was revealed in endometrium cancer patients, even more pronounced in the individuals with a tumor development history aggregated in families. The need for further investigation of development of cancer against genetic background is underlined

EFFICACY OF INTRAPERITONEAL INTERFERON-α ADMINISTRATION FOR TREATMENT OF ENDOMETRIOSIS IN RATS

Directory of Open Access Journals (Sweden)

R. V. Pavlov

2006-01-01

Full Text Available Abstract. The article presents the results of intraperitoneal administration of recombinant rat interferon-α to twenty Wistar rats with experimentally induced endometriosis. The following criteria of treatment efficiency were applied: presence of ectopic endometrium in transplanted segments of cornu uteri, proliferative activity of endometrioid cells, features of vascularization and leucocyte infiltration within endometrial foci. It was shown that local application of interferon-α caused regression of endometrioid epithelial heterotopias in 50 per cent of the cases. If endometrioid epithelium was retained, its proliferative activity did significantly drop under interferon-α application. In all transplants derived from rats treated with interferon-α, the degree of vascularization is reduced, accompanied by increased leucocytic infiltration (due to lymphocytes, along with decreased contents of macrophages within leucocytic infiltrates.

During the period between Jan. 1 1992 and Dec. 31, 1995 at the Second Department of Gynaecology and Obstetrics in Brno labour was induced in 1159 patients by extraamnial fractionated administration of PGE2 vaginal tablets. After assessment of the indication and the baseline examination (NST, amnioscopy, US biometry and cervical score) according to the CS to the patient the first dose of PGE2 was administered into the extraamnial space beyond the inner os uteri (CS 5-8:1.0 mg PGE2, CS > 8 : 0.5 mg PGE2). After two hours the patient was examined again and if regular uterine contractions had started or the finding on the os uteri was larger than 2 cm, the amniotic sac was disrupted. If not, another dose was administered. After two hours the patient was re-examined and if the os was larger than 2 cm, and there were regular uterine contractions, the amniotic sac was disrupted. If the changes did not take place, the induction was considered a failure. there were 1007 successful inductions (95.5%), the mean period from the onset of induction to the onset of uterine contractions was 180 mins.: 322 (29.5%). The mean period of the first stage of labour was 228 mins., stage II 10 mins., stage III 8 mins. Five times uterine hypertonus was recorded and a blood loss greater than 500 ml occurred in four patients. Forty-nine Caesarean sections were made (4.2%) and 51 (4.4%) forceps deliveries. The rate of epidural analgesia was 27 (2.3%). Revision of the uterine cavity was made in 39 patients (3.4%) and manual lysis of the placenta in 30 (2.6%). The Apgar score was inferior to 6 in 10 neonates (0.9%). The protocol of induction of labour described by the authors is effective and associated with a minimum of side-effects, safe for the mother and foetus, well tolerated by patients and cost-effective.

Estradiol stimulates glycogen synthesis whereas progesterone promotes glycogen catabolism in the uterus of the American mink (Neovison vison).

Science.gov (United States)

Bowman, Kole; Rose, Jack

2017-01-01

Glycogen synthesis by mink uterine glandular and luminal epithelia (GE and LE) is stimulated by estradiol (E 2 ) during estrus. Subsequently, the glycogen deposits are mobilized to near completion to meet the energy requirements of pre-embryonic development and implantation by as yet undetermined mechanisms. We hypothesized that progesterone (P 4 ) was responsible for catabolism of uterine glycogen reserves as one of its actions to ensure reproductive success. Mink were treated with E 2 , P 4 or vehicle (controls) for 3 days and uteri collected 24 h (E 2 , P 4 and vehicle) and 96 h (E 2 ) later. To evaluate E 2 priming, mink were treated with E 2 for 3 days, then P 4 for an additional 3 days (E 2 →P 4 ) and uteri collected 24 h later. Percent glycogen content of uterine epithelia was greater at E 2 + 96 h (GE = 5.71 ± 0.55; LE = 11.54 ± 2.32) than E 2 +24 h (GE = 3.63 ± 0.71; LE = 2.82 ± 1.03), and both were higher than controls (GE = 0.27 ± 0.15; LE = 0.54 ± 0.30; P glycogen content (GE = 0.61 ± 0.16; LE = 0.51 ± 0.13), to levels not different from controls, while concomitantly increasing catabolic enzyme (glycogen phosphorylase m and glucose-6-phosphatase) gene expression and amount of phospho-glycogen synthase protein (inactive) in uterine homogenates. Interestingly, E 2 →P 4 increased glycogen synthase 1 messenger RNA (mRNA) and hexokinase 1mRNA and protein. Our findings suggest to us that while E 2 promotes glycogen accumulation by the mink uterus during estrus and pregnancy, it is P 4 that induces uterine glycogen catabolism, releasing the glucose that is essential to support pre-embryonic survival and implantation. © 2016 Japanese Society of Animal Science.

Full Text Available Parag Suresh Mahajan, Nazeer Ahamad, Sheik Akbar Hussain Department of Radiology, Al-Khor Hospital, Hamad Medical Corporation, Doha, Qatar Abstract: An autoamputated wandering calcified ovary (AWCO is an extremely rare cause of abdominal calcification in the pediatric population. We present the magnetic resonance imaging (MRI features of AWCO in a child. To our knowledge, the MRI features of AWCO have not been previously described in the published literature. Our case report indicates that the MRI findings are characteristic in the diagnosis of an AWCO and can completely obviate the need for invasive procedures in this mostly benign disease. An AWCO should be considered in all cases of mobile calcific opacities on radiographs in female patients. We advise that MRI be conducted in all suspected cases of AWCO for accurate and noninvasive diagnosis, and regular follow-up should be performed with ultrasound. The findings in our case report have the potential to change the course of investigations and management in suspected cases.

2011-02-01

Full Text Available Abstract Malignant mixed Müllerian tumor is a rare malignancy of the genital tract and extremely uncommon in extragenital sites. This report describes a case of malignant mixed Müllerian tumor arising in the lower peritoneum of a 72-year-old female patient. The patient presented with ascites, lower abdominal mass and pleural effusion. The serum level of CA125 was elevated. At operation a diffuse carcinosis associated with tumor mass measuring 20 × 15 × 10 cm in the vesicouterine and Duglas' pouch were found. The uterus and the adnexa were unremarkable. Histopathology revealed a typical malignant mixed Müllerian tumor, heterologous type. The epithelial component was positive for cytokeratin 7 and vimentin whereas the mesenchymal component was positive for Vimentin, S100 and focally for CK7. The histogenesis of this tumor arising from the peritoneum is still speculative. Based on the previous reports and the immunohistochemical analysis of our case, we believe that this is a monoclonal tumor with carcinoma being the "precursor" element. Nevertheless, further molecular and genetic evidence is needed to support such a conclusion.

Metastatic adenocarcinoma of the cervix presenting as a choroidal mass: A case report and review of literature of cervical metastases to the eye

2015-01-01

Full Text Available Cervical cancer is the most common cancer among females in India. Cervical cancer usually spreads by local extension and through the lymphatic drainage to the lymph nodes. Hematogenous spread, the mechanism responsible for distant metastases, is rarely seen in cervical malignancies. In this communication, we report a case of a 45-year-old woman who presented with unilateral decrease in vision of 3 months duration. She was found to have a serous retinal detachment with underlying diffuse, subretinal yellowish-cream colored infiltrates in the right eye, suspicious of choroidal metastases. Systemic evaluation showed disseminated systemic metastases arising from a primary adenocarcinoma of the cervix. In this communication, we review all the documented cases of metastases to the eye and adnexa arising from cervical cancer and their clinical characteristics. Unilateral choroidal metastasis arising from an adenocarcinoma of the cervix is extremely rare with only one previous documented case. Although uncommon, choroidal metastasis may be the presenting feature of primary cervical malignancy. Furthermore, cervical malignancy must be ruled out in women who present with orbital or choroidal metastases arising from unknown primary.

Contrast-enhanced ultrasound and computed tomography findings of recurrent ovarian steroid cell tumor presenting with peritoneal seeding: A case report

2013-01-01

We present ultrasonography and computed tomography (CT) findings of a case of recurrent ovarian steroid cell tumor presenting with peritoneal seeding in a 45-year-old woman. On abdominal ultrasonography, there were multiple hypoechoic round masses in the peritoneal cavity including the perihepatic area. Contrast-enhanced ultrasonography showed intense homogenous enhancement on the arterial phase and delayed prolonged enhancement of the masses. CT revealed multiple peritoneal solid masses with strong enhancement. Five years ago, the patient had been diagnosed with a steroid cell tumor of the left ovary. At that time, the CT showed a well-enhancing, lobulating, large solid mass at the left adnexa. Imaging findings of the peritoneal masses suggested peritoneal seeding from the preexisting ovarian steroid cell tumor. For treatment of the metastatic lesions in the perihepatic area, ultrasonography-guided radiofrequency ablation (RFA) was performed, and debulking surgery for the peritoneal masses was done. Six months later, complete ablation of the perihepatic metastases by RFA and a marked decrease in the peritoneal metastases by surgery were found on the follow-up CT.

Molecular Pathogenesis of MALT Lymphoma

Directory of Open Access Journals (Sweden)

Katharina Troppan

2015-01-01

Full Text Available Approximately 8% of all non-Hodgkin lymphomas are extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MALT, also known as MALT lymphoma, which was first described in 1983 by Isaacson and Wright. MALT lymphomas arise at a wide range of different extranodal sites, with the highest frequency in the stomach, followed by lung, ocular adnexa, and thyroid, and with a low percentage in the small intestine. Interestingly, at least 3 different, apparently site-specific, chromosomal translocations and missense and frameshift mutations, all pathway-related genes affecting the NF-κB signal, have been implicated in the development and progression of MALT lymphoma. However, these genetic abnormalities alone are not sufficient for malignant transformation. There is now increasing evidence suggesting that the oncogenic product of translocation cooperates with immunological stimulation in oncogenesis, that is, the association with chronic bacterial infection or autoaggressive process. This review mainly discusses MALT lymphomas in terms of their genetic aberration and association with chronic infections and summarizes recent advances in their molecular pathogenesis.

The authors describe a 31 year-old female who presented emergently with abdominal pain and was found at CT to have complete genitourinary duplication including separate urinary bladders, uteri, cervices, and vaginas, and also duplication of the rectum. No etiology for abdominal pain was identified. The patient was referred to urology for further evaluation, and an intravenous urographic study was obtained, which confirmed complete lower urinary tract duplication. The patient presented emergently 9 months later during a subsequent pregnancy for further evaluation of abdominal pain. A second CT scan was ordered to rule out appendicitis. Findings consistent with cloacal duplication were again noted. There was also dilatation of the urinary collecting systems, more prominently on the right side. A Cesarean section was performed and confirmed total genitourinary and rectal duplication.

1987-01-01

When main ingredients of cleansers, alcohol sulfate (AS) and linear alkylbenzene sulfonate (LAS), were applied to the dorsal skin of pregnant JCL:ICR mice during preimplantation period, significant numbers of embryos collected from the oviducts and uteri on day 3 showed severe deformity or remained at the morula stage. Most of abnormal embryos were fragmented or remained at the 1-8 cell stages, and they were either dead or dying. Similar results were observed with commercially obtained kitchen detergent and hair shampoo. Fertilized eggs may be specifically sensitive to synthetic detergents. Very low doses of X-rays also induced significant yields of abnormal embryos. Major difference between X-rays and detergents was that X-ray-induced abnormality appeared at the morula or blastocyst stage, while detergent-induced one did at the earlier stages. (Auth.)

Purpose: To assess the outcome of patients treated with radical radiotherapy for cervical cancer who received an external beam boost, in place of intracavitary brachytherapy (ICT), after irradiation to the whole pelvis. Methods and Materials: Case notes were reviewed for all patients treated in this way in a single center between 1996 and 2004. Patient and tumor details, the reasons why ICT was not possible, and treatment outcome were documented. Results: Forty-four patients were identified. The mean age was 56.4 years (range, 26-88 years). Clinical International Federation of Gynecology and Obstetrics or radiologic stage for Stages I, II, III, and IV, respectively, was 16%, 48%, 27%, and 7%. A total radiation dose of 54-70 Gy was given (75% received ≥60 Gy). Reasons for ICT not being performed were technical limitations in 73%, comorbidity or isolation limitations in 23%, and patient choice in 4%. The median follow-up was 2.3 years. Recurrent disease was seen in 48%, with a median time to recurrence of 2.3 years. Central recurrence was seen in 16 of the 21 patients with recurrent disease. The 5-year overall survival rate was 49.3%. The 3-year cancer-specific survival rate by stage was 100%, 70%, and 42% for Stages I, II, and III, respectively. Late Grades 1 and 2 bowel, bladder, and vaginal toxicity were seen in 41%. Late Grade 3 toxicity was seen in 2%. Conclusion: An external beam boost is a reasonable option after external beam radiotherapy to the pelvis when it is not possible to perform ICT

A retrospective chart review and questionnaire study was undertaken to look at the long-term effects of radiation therapy in ovarian dysgerminoma patients. Forty-three patients and 55 controls responded to a questionnaire that detailed bowel, bladder, thyroid, menstrual, reproductive, sexual, and growth function. Statistically significant differences in the number of bowel movements were noticed when comparing patients with controls. The authors noticed no significant differences between cases and controls in bladder function. No thyroid disorders were attributable to mediastinal radiation therapy. Most patients with intact uteri bleed monthly on hormonal replacement. Three patients with a remaining ovary and uterus resumed menstrual function after substantial doses of abdominopelvic radiation therapy. No patients have conceived. The authors noticed a slight increase in dyspareunia in the treated group, but most patients were satisfied with their sexual function. One premenarchal patient exhibited a growth disorder

To determine the effect of abdominal and/or pelvic irradiation for gynecological malignancies on the later development of hyperthyroidism, 1,884 medical records of the patients diagnoses as carcinomas of cervix and corpus uteri, and of ovary were reviewed. Among 1,269 patients with radiation therapy, 5 patients developed hyperthyroidism after irradiation to the abdomen and/or pelvis. This is a statistically significant increase when compared with an epidemiological study. Radiation dose to the thyroid was estimated to be 30 to 200 rads. Two other patients who were irradiated to the nose or supraclavicular region in addition to the abdomen also developed hyperthyroidism. However, none of 581 patients without radiation therapy became hyperthyroid. The results indicate that radiation therapy for treatment of gynecological malignancy gives a significant radiation exposure with an increase in the incidence of subsequent hyperthyroidism

BACKGROUND: In 1975, estrogen only was found to be associated with an increased risk of endometrial cancer. In November 2015, NICE guidelines on hormone therapy were published that did not take this risk into account. AIM: This systematic literature review assesses the safety of estrogen plus...... progestin therapy according to the risk of endometrial cancer, while considering both regimen and type of progestin. METHODS: PubMed, EMBASE and the Cochrane Library were searched, resulting in the identification of 527 published articles on menopausal women with intact uteri treated with estrogen only......, estrogen plus progestin or tibolone for a minimum of one year. Risk of endometrial cancer was compared to placebo or never users and measured as relative risk, hazard or odds ratio. RESULTS: 28 studies were included. The observational literature found an increased risk among users of estrogen alone...

Full Text Available Objective. To compare the expression of G-protein-coupled estrogen receptor (GPER in the junctional zone and outer myometrium of the proliferative and secretory phases of women with and without adenomyosis. Methods. A total of 76 women were included in this study, 42 with adenomyosis (proliferative phase, n=23; secretory phases, n=19 and 34 controls (proliferative phase, n=16; secretory phases, n=18. Protein and total RNA were extracted from the junctional zone (JZ and outer myometrium (OM. GPER protein and mRNA expression levels were evaluated by the use of western blotting and real-time quantitative polymerase chain reaction (RT-qPCR. Results. The expression of GPER protein and mRNA in women with adenomyosis was significantly higher than that of control subjects, both in the junctional zone and in the outer myometrium and both in the proliferative and in the secretory phases. Conclusion. The significant and consistent increase in GPER expression in adenomyosis compared with control subjects, regardless of whether it was in the proliferative or secretory phases and regardless of whether it was in the JZ or OM, suggests that GPER plays an important role in the pathogenesis of the adenomyosis.

to verify the accuracy of uterine cervix cytology for HPV diagnosis, as compared to polymerase chain reaction (PCR) in samples of women with HIV. 158 patients who had undergone a first collection of material from the uterine cervix with Ayre's spatula for PCR were included in the study. Then, another collection with Ayre's spatula and brush for oncotic cytology was performed. Only 109 slides were reviewed, as 49 of them had already been destructed for have being filed for over two years. the prevalence of HPV was 11% in the cytological exam and 69.7% in the PCR. Age varied from 20 to 61 years old, median 35 years. The HIV contagious route was heterosexual in 91.8% of the cases, and 79.1% of the patients had had from one to five sexual partners along their lives. The most frequent complaint was pelvic mass (5.1%), and 75.3% of the women had looked for the service for a routine medical appointment. The categorical variable comparison was done through contingency tables, using the chi2 test with Yates's correction to compare the ratios. The Fisher's test was used when one of the expected rates was lower than five. In the comparison of diagnostic tests, sensitivity, specificity and similarity ratios have been calculated. Among the 76 patients with HPV, detected by PCR, only 12 had the diagnosis confirmed by cytology (sensitivity=15.8%), which on the other hand did not present any false-positive results (specificity=100%). Concerning the HPV presence, the cytological prediction for positive results was 100% and 33.3% for negative, when both results were compared. Among the 12 patients with HPV positive cytology, four (33.3%) presented cervical intraepithelial neoplasia (OR=56; positive similarity ratio=positive infinity; negative similarity ratio=0.83). As the cytology specificity is quite high, it is possible to rely on the positive result, which means that a positive result will surely indicate the presence of HPV. The low sensitivity of cytology does not qualify it as a survey exam for HPV detection in this female group.

Objective: To report an aggressive case of extranodal natural killer/T-cell lymphoma (NKTCL) of the ethmoid sinus presenting as orbital cellulitis Method: Case report Results: A 56-year-old male presented with right eye redness, reduced vision, and periorbital swelling for 5 weeks duration associated with a two-month history of blocked nose. The visual acuity of the right eye was 6/18. The eye was proptosed with periorbital oedema and conjunctival chemosis. The pupil was mid-dilated but there was no relative afferent pupillary defect. The fundus was normal. The extraocular movements were restricted in all directions of gaze. Nasal endoscopy revealed pansinusitis that corresponded with CT scan orbit and paranasal sinuses findings. Despite treatment, he showed no clinical improvement. Ethmoidal sinus biopsies performed revealed extranodal NKTCL. Further imaging showed involvement of the right orbital contents and its adnexa with intracranial extension into the right cavernous sinus and meninges over right temporal fossa. The patient underwent chemotherapy. However he succumbed to his illness two months after the diagnosis. Conclusion: Extranodal NKTCL is a great mimicker. This case demonstrated how an acute initial presentation of extranodal NKTCL can present as orbital cellulitis with pansinusitis. PMID:28194321

Odontogenic keratocyst (OKC) of the buccal mucosa, the diagnosis of which is based on subjective histologic evaluation, is a controversial entity of questionable existence. This report describes 2 rare cases of parakeratinized cyst arising from the buccal mucosa. Case 1 was a 60-year-old man with a 3-cm cyst and case 2 was a 16-year-old boy with a microcyst incidentally discovered on histology. Both lesions were essentially identical in histologic appearance and immunophenotype to intraosseous and gingival OKC, but they were clearly different from orthokeratinized odontogenic cysts and buccal mucosal epidermoid cysts. Step sections failed to reveal any kind of odontogenic tissue or skin adnexa in the cyst wall. These microscopic characteristics reflexively lead to the diagnosis of OKC, if the extragingival occurrence in the buccal mucosa cannot be considered. An alternative nonodontogenic origin includes a keratocyst of the skin, ie, an unusual mucosal presentation of cutaneous keratocyst. Because its true nature, either odontogenic or epidermal, cannot be conclusively proven at this time, we propose a more descriptive and noncommittal term, "mucosal keratocyst," for a particular cyst in a buccal location that is morphologically indistinguishable from OKC.

Primary leiomyoma of the ovary is a rare benign ovarian tumor that only seldom causes acute abdomen. A 35-year-old gravida 1, para 0 woman presented with a history of acute lower abdominal pain, and 10 weeks of amenorrhea. The patient's physical examination revealed abdominal tenderness, defense, and rebound. On ultrasonographic examination, a solid mass measuring 9.3 × 7.8 cm was detected adjacent to the uterine fundus. The mass was preoperatively diagnosed as a twisted pedunculated subserosal uterine myoma. Upon entering the pelvic cavity, the mass in the right adnexa appeared twisted clockwise. Therefore, a laparoscopic salpingo-oophorectomy was performed. The tumor was pathologically diagnosed as ovarian leiomyoma. The patient delivered a healthy girl at 40 1/7 weeks of pregnancy. Despite its low incidence, torsion of ovarian leiomyoma should be considered in the differential diagnosis of acute abdomen. Furthermore, laparoscopic exploration should be the preferred way of removing twisted ovarian leiomyoma, even during pregnancy. It seems that primary ovarian leiomyomata have a tendency to grow rapidly during early pregnancy. However, because of the low incidence of ovarian leiomyoma, the effects of estrogen and pregnancy on this condition remain unclear.

This study aimed to evaluate the impact on perioperative and medium-term oncologic outcomes of the implementation of laparoscopy into a preexisting oncologic setting. Data from consecutive 736 patients undergoing surgery for apparent early stage gynecological malignancies (endometrial, cervical, and adnexal cancers) between 2000 and 2011 were reviewed. Complications were graded per the Accordion classification. Survival outcomes within the first 5 years were analyzed using Kaplan-Meier method. Overall, 493 (67%), 162 (22%), and 81 (11%) had surgery for apparent early stage endometrial, cervical, and adnexal cancer. We assisted at an increase of the number of patients undergoing surgery via laparoscopy through the years (from 10% in the years 2000-2003 to 82% in years 2008-2011; P 0.05). The introduction of laparoscopy did not adversely affect medium-term (within 5 years) survival outcomes of patients undergoing surgery for apparent early stage cancers of the endometrium, uterine cervix, and adnexa (P > 0.05 log-rank test). The introduction of laparoscopy into a preexisting oncologic service allows an improvement of standard of care due to a gain in perioperative results, without detriments of medium-term oncologic outcomes.

Full Text Available Abstract Background To describe a rare manifestation of mantle cell lymphoma (MCL in conjunctiva, with clinical, hisologic, immunohistologic and genetic findings together with review of the Literature. Case presentation Most ocular adnexal lymphomas are extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT. A few cases of ocular adnexal mantle cell lymphomas have been reported in the literature. We present a case of mantle cell lymphoma presenting as right conjunctival mass of at least three months duration in a 64-year-old man. Histopathologic examination showed a proliferation of monomorphous small-to-medium-sized lymphoid cells with cleaved nuclei in the subconjunctiva. By immunohistochemistry, the infiltrate was positive for CD20, CD5, BCL-2, cyclin D1, and the transcription factor SOX11. Fluorescent in situ hybridization demonstrated the presence of IGH-CCND1 fusion indicating t(11;14. Conclusion A rigorous approach to initial diagnosis and staging of small cell lymphomas of the ocular adnexa is needed. The recognition of ocular MCL requires appropriate immunohistochemical staining and/or genetic confirmation to differentiate this rare form of presentation of MCL from other more frequent small cell lymphomas.

Definition of Sudden Infant Death and Sudden Intrauterine Unexpected Death Syndromes (SIDS and SIUDS with Regard to the Anatomo-Pathological Examination

2016-09-01

Full Text Available Crib death, or sudden infant death syndrome (SIDS, is the most frequent form of death in the first year of life, striking one baby in every 1,700–2,000. Yet despite advances in maternal-infant care, sudden intrauterine unexplained/unexpected death syndrome (SIUDS, has a six-eightfold greater incidence than that of SIDS. Frequent congenital abnormalities, likely morphological substrates for SIDS-SIUDS, were detected, mainly represented by alterations of the cardiac conduction system, such as accessory pathways and abnormal resorptive degeneration, and hypoplasia/agenesis of the vital brainstem structures. On the basis of these considerations, the new common definition of the SIDS-SIUDS complex is The sudden death of a fetus after the 25th gestational week or infant under one year of age which is unexpected by history and remains unexplained after a thorough case investigation, including examination of the death scene, performance of a general autopsy and examination of the fetal adnexa. Therefore, given that the general autopsy does not disclose any cause of death, a more in-depth histopathological analysis of the cardiac conduction system and autonomic nervous system by specialized pathologists will become necessary.

An i.p. injection of a solution of thallium acetate in deionized water at a dose of 32 mg/kg, in 24-h-old rats, produces morphological and biochemical alterations in both cartilaginous and osseous tissues. From the beginning, there are alterations in the cartilaginous cell as well as in chrondrine, osteoblasts, osseous tissue and bone marrow. Rats were sacrificed at 24, 48, and 72 h and also at 7 days. Two animals survived for 50 days. One showed total irreversible alopecia while the other one had partial alopecia with discrete recovery. Both showed a low weight and a size of 8 cm. Microscopically, degenerative changes were produced consisting of alteration and death of many cartilaginous cells, uneven metachromasia and the chondrine and decrease of the growth cartilage, scanty bone trabeculae with few osteoblasts. The bone marrow showed few myeloblasts and megakaryocytes. Progressive cellular damage throughout the 50 days of survival represents a response of the thallium ionic accumulation and recycling in cellular mitochondria of all the body's cells. This appeared in our study as irreversible and progressive osteochondral alterations with atrophy of the skin and its adnexa, hyalinization of elastic and collagenous fibers with intense interstitial edema.

Cancer is one of the major health problems worldwide. In this article, we present for the first time the cancer incidence trends, the distribution and the socioeconomic profile of incident cancer cases in Eastern Morocco over a period of eight years. Retrospective descriptive study of patients diagnosed with cancer at the Hassan II Regional Oncology Center (ROC) since it was created in October 2005 until December 2012. During the study period, the ROC was the only hospital specialized in cancer care in Eastern Morocco. A total of 7872 incident cases of cancer were registered in Eastern Morocco. Among these incident cases 5220 cases were women and 2652 were men, with a female to male ratio of 1.97. The mean age at diagnosis was 58 years for males and 52 for females and 94% of the patients aged over 30 years. For both sexes combined and for all cancer sites, breast cancer was the commonest followed by cervix uteri, colon-rectum, lung, nasopharynx, and stomach cancers. The most common cancer in women was breast cancer, followed respectively by cervix uteri cancer, colon-rectum cancer, ovary cancer, and stomach cancer. In men, the lung cancer ranked first, followed respectively by colon-rectum cancer, nasopharynx cancer, prostate cancer, and stomach cancer. For most cancers, crude incidence rates (CR) have increased significantly. The CR for all cancers combined has increased from 56.6 to 80.3 per 100,000 females and from 32.3 to 42.6 per 100,000 males during the study period. Patients profile analysis showed that 79% of cancer patients were from urban areas, 83% were unemployed and 85% had no health insurance. The distribution of cancers in Eastern Morocco is different from those observed in other regions of Morocco. Unlike most countries, women were much more affected with cancer than men in Eastern Morocco. More importantly, the rates of many cancers are rising. Therefore, our data justify the need to develop effective programs for cancer control and prevention in

Description of cervical cancer mortality in Belgium using Bayesian age-period-cohort models

Science.gov (United States)

2009-01-01

Objective To correct cervical cancer mortality rates for death cause certification problems in Belgium and to describe the corrected trends (1954-1997) using Bayesian models. Method Cervical cancer (cervix uteri (CVX), corpus uteri (CRP), not otherwise specified (NOS) uterus cancer and other very rare uterus cancer (OTH) mortality data were extracted from the WHO mortality database together with population data for Belgium and the Netherlands. Different ICD (International Classification of Diseases) were used over time for death cause certification. In the Netherlands, the proportion of not-otherwise specified uterine cancer deaths was small over large periods and therefore internal reallocation could be used to estimate the corrected rates cervical cancer mortality. In Belgium, the proportion of improperly defined uterus deaths was high. Therefore, the age-specific proportions of uterus cancer deaths that are probably of cervical origin for the Netherlands was applied to Belgian uterus cancer deaths to estimate the corrected number of cervix cancer deaths (corCVX). A Bayesian loglinear Poisson-regression model was performed to disentangle the separate effects of age, period and cohort. Results The corrected age standardized mortality rate (ASMR) decreased regularly from 9.2/100 000 in the mid 1950s to 2.5/100,000 in the late 1990s. Inclusion of age, period and cohort into the models were required to obtain an adequate fit. Cervical cancer mortality increases with age, declines over calendar period and varied irregularly by cohort. Conclusion Mortality increased with ageing and declined over time in most age-groups, but varied irregularly by birth cohort. In global, with some discrete exceptions, mortality decreased for successive generations up to the cohorts born in the 1930s. This decline stopped for cohorts born in the 1940s and thereafter. For the youngest cohorts, even a tendency of increasing risk of dying from cervical cancer could be observed, reflecting

Distinct spatiotemporal expression of serine proteases Prss23 and Prss35 in periimplantation mouse uterus and dispensable function of Prss35 in fertility.

Directory of Open Access Journals (Sweden)

Honglu Diao

Full Text Available PRSS23 and PRSS35 are homologous proteases originally identified in mouse ovaries. In the periimplantation mouse uterus, Prss23 was highly expressed in the preimplantation gestation day 3.5 (D3.5 uterine luminal epithelium (LE. It disappeared from the postimplantation LE and reappeared in the stromal compartment next to the myometrium on D6.5. It was undetectable in the embryo from D4.5 to D6.5 but highly expressed in the embryo on D7.5. Prss35 became detectable in the uterine stromal compartment surrounding the embryo on D4.5 and shifted towards the mesometrial side of the stromal compartment next to the embryo from D5.5 to D7.5. In the ovariectomized uterus, Prss23 was moderately and Prss35 was dramatically downregulated by progesterone and 17β-estradiol. Based on the expression of Prss35 in granulosa cells and corpus luteum of the ovary and the early pregnant uterus, we hypothesized that PRSS35 might play a role in female reproduction, especially in oocyte development, ovulation, implantation, and decidualization. This hypothesis was tested in Prss35((-/- mice, which proved otherwise. Between wild type (WT and Prss35((-/- mice, superovulation of immature females produced comparable numbers of cumulus-oocyte complexes; there were comparable numbers of implantation sites detected on D4.5 and D7.5; there were no obvious differences in the expression of implantation and decidualization marker genes in D4.5 or D7.5 uteri. Comparable mRNA expression levels of a few known protease-related genes in the WT and Prss35((-/- D4.5 uteri indicated no compensatory upregulation. Comparable litter sizes from WT × WT and Prss35((-/-× Prss35((-/- crosses suggested that Prss35 gene was unessential for fertility and embryo development. Prss35 gene has been linked to cleft lip/palate in humans. However, no obvious such defects were observed in Prss35((-/- mice. This study demonstrates the distinct expression of Prss23 and Prss35 in the periimplantation uterus

Endometrial stromal beta-catenin is required for steroid-dependent mesenchymal-epithelial cross talk and decidualization

2012-09-01

Full Text Available Abstract Background Beta-catenin is part of a protein complex associated with adherens junctions. When allowed to accumulate to sufficient levels in its dephosphorylated form, beta-catenin serves as a transcriptional co-activator associated with a number of signaling pathways, including steroid hormone signaling pathways. Methods To investigate the role of beta-catenin in progesterone (P4 signaling and female reproductive physiology, conditional ablation of Ctnnb1 from the endometrial mesenchymal (i.e. stromal and myometrial, but not epithelial, compartment was accomplished using the Amhr2-Cre mice. Experiments were conducted to assess the ability of mutant female mice to undergo pregnancy and pseudopregnancy by or through oil-induced decidualization. The ability of uteri from mutant female mice to respond to estrogen (E2 and P4 was also determined. Results Conditional deletion of Ctnnb1 from the mesenchymal compartment of the uterus resulted in infertility stemming, in part, from complete failure of the uterus to decidualize. E2-stimulated epithelial cell mitosis and edematization were not altered in mutant uteri indicating that the mesenchyme is capable of responding to E2. However, exposure of ovariectomized mutant female mice to a combined E2 and P4 hormone regimen consistent with early pregnancy revealed that mesenchymal beta-catenin is essential for indirectly opposing E2-induced epithelial proliferation by P4 and in some mice resulted in development of endometrial metaplasia. Lastly, beta-catenin is also required for the induced expression of genes that are known to play a fundamental role in decidualization such as Ihh, Ptch1, Gli1 and Muc1 Conclusions Three salient points derive from these studies. First, the findings demonstrate a mechanistic linkage between the P4 and beta-catenin signaling pathways. Second, they highlight an under appreciated role for the mesenchymal compartment in indirectly mediating P4 signaling to the epithelium

To describe the histologic distribution of elastin in the nonpregnant human uterus, uterine leiomyomas, adenomyosis and adenomyomas. Uteri were obtained from women undergoing hysterectomy for benign conditions, including 26 cases of uterine leiomyomas, 24 cases of adenomyosis, 18 adenomyomas and 6 cases of autopsy specimens. Specific histochemical staining techniques were employed in order to demonstrate the distribution of elastin. The distribution of elastin components in the uterus was markedly uneven and showed a decreasing gradient from outer to inner myometrium. No elastin was present within leiomyomas, adenomyomas or adenomyosis. The distribution of elastin may help explain the normal function of the myometrium in labor. It implies that the uneven distribution of elastin components and absence of elastin within leiomyomas, adenomyomas and adenomyosis could be of some clinical significance. The altered elastin distribution in disease states may help explain such symptoms as dysmenorrhea in uterine endometriosis.

Although radioisotopes of iodine have been used extensively as radiopharmaceutical labels, there are several advantages associated with the use of radiobromine as a label, due primarily to increased stability of bonds to the radiohalide and smaller steric perturbation resulting from substitution of the radiohalide. Methods of attaching radiobromine to receptor ligands with the potential of mapping estrogen receptors in mammary tumors and uteri were studied. Two ligands were studied extensively in vitro and in animal models; preliminary studies were also carried out in humans. To date, the only radioisotope of bromine used was bromine-77. In addition, a series of model compounds were labeled with bromine-77 using a recently described method for rapid bromination; the scope and limitations of this new rapid radiobromination technique were evaluated

A meta-analysis on uterine transplantation: Redefining the limits of reproductive surgery

Directory of Open Access Journals (Sweden)

Ana Flávia Garcia Silva

Full Text Available SUMMARY In September 2014, the first baby grown in a transplanted uterus was born, which represented an astonishing scientific progress that will mark the history of human reproduction. The recipient was a 32-year-old woman with Rokytanski syndrome who became pregnant after a successful embryo transfer and had an uneventful pregnancy, giving birth to a healthy newborn and marking the beginning of a new era. Patients who do not have a uterus or have a dysfunctional uterus now have the chance of dreaming with pregnancy and motherhood. Combining principles of solid organ transplantation and techniques of human reproduction, uterus transplantation is the first ephemeral transplant performed in order to promote reproductive potential of women and may be removed after successful pregnancy. Worldwide, 11 uterine transplantations were performed in patients. Of these, seven maintained their reproductive potential, with viable transplanted uteri and regular menstrual cycles.

Full Text Available The Brazilian endemic deep-water onefin skate (Gurgesiella dorsalifera is a rare small species recently described in the 80's. No biological information is available on this species and its extremely restricted geographic distribution has been used to classify it as a vulnerable species under IUCN red list criteria. Twenty four specimens (115 to 207 mm disc width were captured off southern Brazilian coast at the region of Cape Santa Marta Grande (State of Santa Catarina by deep-water otter trawl (430-524 m. The analysis of stomach contents revealed an apparent opportunistic predation on juveniles of Urophycis brasiliensis (IRI = 6944, with an average total length of 21 mm, followed by mysidaceans (IRI = 2938, unidentified teleosts (IRI = 1969, the copepod Bradyidius plinioi (IRI = 393, and decapod crustaceans (IRI = 297. One mature female with 207 mm DW had two egg cases in its uteri.

Since the safety warning from the US Food and Drug Administration on the use of power morcellators, minimally invasive procedures involving the removal of uterine myomas and large uteri are under scrutiny. Growing evidence suggests that morcellation of undiagnosed uterine malignancies is associated with worse survival outcomes of patients affected by uterine sarcoma. However, to date, only limited data regarding morcellation of low-grade uterine neoplasms are available. In the present article, we reported a case of a (morcellator) port-site implantation of a smooth muscle tumor that occurred 6 years after laparoscopic morcellation of a uterine smooth muscle tumor of uncertain potential. This case highlights the effects of intra-abdominal morcellation, even in low-grade uterine neoplasms. Caution should be used when determining techniques for tissue extraction; the potential adverse consequences of morcellation should be more fully explored. Copyright © 2016 AAGL.

Involvement of the Reck tumor suppressor protein in maternal and embryonic vascular remodeling in mice

Directory of Open Access Journals (Sweden)

Kitayama Hitoshi

2010-08-01

Full Text Available Abstract Background Developmental angiogenesis proceeds through multiple morphogenetic events including sprouting, intussusception, and pruning. Mice lacking the membrane-anchored metalloproteinase regulator Reck die in utero around embryonic day 10.5 with halted vascular development; however, the mechanisms by which this phenotype arises remain unclear. Results We found that Reck is abundantly expressed in the cells associated with blood vessels undergoing angiogenesis or remodelling in the uteri of pregnant female mice. Some of the Reck-positive vessels show morphological features consistent with non-sprouting angiogenesis. Treatment with a vector expressing a small hairpin RNA against Reck severely disrupts the formation of blood vessels with a compact, round lumen. Similar defects were found in the vasculature of Reck-deficient or Reck conditional knockout embryos. Conclusions Our findings implicate Reck in vascular remodeling, possibly through non-sprouting angiogenesis, in both maternal and embyornic tissues.

The incidence of obesity, increased weight gain and the popularity of high-fat \\/ high-sugar diets are seriously impacting upon the global population. Billions of individuals are affected, and although diet and lifestyle are of paramount importance to the development of adult obesity, compelling evidence is emerging which suggests that maternal obesity and related disorders may be passed on to the next generation by non-genetic means. The processes acting within the uteri of obese mothers may permanently predispose offspring to a diverse plethora of diseases ranging from obesity and diabetes to psychiatric disorders. This review aims to summarise some of the molecular mechanisms and active processes currently known about maternal obesity and its effect on foetal and neonatal physiology and metabolism. Complex and multifactorial networks of molecules are intertwined and culminate in a pathologically synergistic manner to cause disruption and disorganisation of foetal physiology. This altered phenotype may potentiate the cycle of intergenerational transmission of obesity and related disorders.

Full Text Available In November 2013, a woman with Herlyn-Werner-Wunderlich (HWW syndrome was diagnosed with a locally advanced left cervical adenocarcinoma. The patient’s malformation consisted of two uteri with two cervixes, a obstructed vagina, and a left renal agenesis. Classification FIGO: stage IIIa because of infiltration of the inferior third of the vagina wall. Locoregional management comprised an infrarenal lateral aortic lymphadenectomy followed by concomitant radio-chemotherapy to the pelvic (inguinal, pelvic, and infrarenal para aortic nodes volumes. A total of 50.4 Gy were delivered (1.8 Gy/fraction/day to the node (inguinal, pelvic, and aortic infrarenal and pelvic volume; a concomitant boost to the primary cervical tumor and macroscopic nodes to 59.92 Gy (2.14 Gy/fraction/day was performed. 20 Gy were delivered with intracavitary brachytherapy boost with mold technique and a pulsed-dose-rate technique due to the rarity of this uterine malformation. After 30 months of follow-up, there was no evidence of locoregional or distant recurrence.

280 women have been tested by FISH to detect an HPV 16/18-infection of the portio uteri. In a group of 133 women treated by conisation (all with a history of abnormal smear and colposcopy) 67 (50%) were positive for HPV 16/18 DNA before the operation. Follow up examinations of 20 cases with positive HPV 16/18 test before conisation, showed 6 and 12 months after operation only in 3 cases a persistence of HPV 16/18 infection. Only 5 (6.4%) of 78 women with a history of conisation and diagnosis CIN III some years ago were positive for HPV 16/18. In another group of 47 elderly women, treated by abrasio and with normal cervical histology, only 5 (10.6%) had a positive result in the HPV 16/18 FISH-test. 2 (10.6%) of 22 women with normal smear and colposcopy (control group) were positive for HPV 16/18.

Urman, B.; Gomel, V.; Jetha, N. (Department of Obstetrics and Gynecology, University of British Columbia, Vancouver (Canada))

1991-09-01

The aim of this study was to determine the effectiveness of hyaluronic acid solution in preventing intraperitoneal (IP) adhesions. The study design was prospective, randomized and blinded and involved 83 rats. Measured serosal injury was inflicted using a CO2 laser on the right uterine horn of the rat. Animals randomized to groups 1 and 2 received either 0.4% hyaluronic acid or its diluent phosphate-buffered saline (PBS) intraperitoneally before and after the injury. In groups 3 and 4, the same solutions were used only after the injury. Postoperative adhesions were assessed at second-look laparotomy. Histologic assessment of the fresh laser injury was carried out on uteri pretreated with hyaluronic acid, PBS, or nothing. Pretreatment with hyaluronic acid was associated with a significant reduction in postoperative adhesions and a significantly decreased crater depth. Hyaluronic acid appears to reduce postoperative IP adhesion formation by coating the serosal surfaces and decreasing the extent of initial tissue injury.

A cohort study designed to evaluate the carcinogenicity of treatment for Hodgkin's disease (HD) was begun in 1976. This report describes 1,553 patients diagnosed with HD in 1940-75 and presents an analysis of follow-up findings through 1976. Twenty-seven cancers (excluding basal cell and squamous cell carcinomas of skin, trichoepitheliomas, and in situ carcinomas of cervix uteri) were observed 1 year or more after diagnosis of HD, including 6 leukemias. The relative risk (RR) of leukemia in patients treated with intensive chemotherapy with or without radiotherapy relative to general population incidence rates was 140 (95% confidence limits: 50,300). In the subgroup treated with both intensive radiotherapy and intensive chemotherapy, the RR of leukemia was 270 (95% confidence limits: 56,800). No leukemia occurred after treatment with intensive radiotherapy without chemotherapy. For cancers other than leukemia and for non-HD lymphomas, RR was generally not significantly different from the null value one

Artemether, highly effective in multi-drug-resistant malaria is not routinely available for use in pregnancy due to the lack of adequate research data in animals and man. This study was therefore aimed at investigating some pregnancy-related effects of artemether. Artemether (1.5, 7.5 and 15 mg/kg i.p. daily for 7 days) did not produce changes in rat oestrous cycle. The drug did not prevent or prolong the rate of conception or parturition, cause pre-term delivery and affect litter size. Birth weight and growth rate of pups from artemether-pretreated dams were within the normal range. Artemether (48-480 microg/ml) had no agonist effect on the isolated uterine smooth muscles of both non-pregnant and pregnant rats and guinea pigs. However, the drug (24- 240 microg/ml) reduced oxytocin-induced contraction of uterine tissues concentration-dependently, particularly in pregnant uteri. Copyright (c) 2006 S. Karger AG, Basel.

the expression of SK3 in the uterus of rats stimulated with 17β-estradiol and progesterone in order to get an in depth understanding of the rat uterine SK3. Using immunohistochemistry SK3 was localized to the glandular and luminal endometrial lamina epitheliali. Furthermore, a weak signal was observed...... in the myometrium. Using Western blot the protein level of SK3 was found to increase in uteri from animals treated with 17β-estradiol, an effect that was not reflected at the mRNA level. The levels of mRNA for SK3 were significantly lower in the uterus of 17β-estradiol-treated animals than in the uterus...... of ovariectomized animals. We conclude that the SK channels are present in the endometrial epithelium, and possibly also in the myometrium of the rat uterus. Furthermore, the hormonal effect on SK3 caused by 17β-estradiol includes divergent regulation at mRNA and protein levels....

The aim of the present study was to demonstrate the possible transplacental transmission of 131 I labeled recombinant human erythropoietin ( 131 I-rh-EPO) in pregnant rats and its distribution through maternal and fetal organs. Six Wistar Albino Rats in their pregnancy of 18 days were used 131 I labeled recombinant human erythropoietin (specific activity = 2.4 μCi/IU) was injected into the tail vein of rats. After 30 minutes labeled erythropoietin infusion maternal stomach, kidney, lung, liver, brain and heart as well as fetus were removed. Then, the same organs were removed from each fetus. Measuring weight of maternal and fetal organs as well as placenta were followed by radioactivity count via Cd(Te) detector. 131 I labeled recombinant human erythropoietin was found to be able to pass rat placenta and its distribution order in fetal organs was similar to those of maternal organs. Besides, as measurements were performed closer to cornu uteri, uptakes were decreasing in every fetus and its corresponding placenta. (author)

Objective: To assess the efficacy and safety of emergency transcatheter arterial embolization in the management of intractable postpartum hemorrhage. Methods: Twenty-five patients with intractable postpartum hemorrhage were undertaken superselective catheterization into the bilateral internal iliac arteries or uterial arteries to find the causes and sites of bleeding through DSA and then followed by arterial embolization with gelfoam particles. Result: All of the 25 patients with obstetrical bleeding were successfully controlled by TAE, the procedure lasted for 25-60 min, (mean 42.5 ± 4.6 min); with both catheterization and bleeding halt successful rates of 100%. Comparison of hemoglobin and heartbeat before and after the procedure showed significance (t=29.49, P<0.01; t=16.51, P<0.01). The uterus showed reintegration on time and menstruation resumed in all patients. Conclusions: Emergency arterial embolization is a safe and effective means for control of intractable postpartum hemorrhage, providing less trauma and no severe complications, especially as an unique management for fetal postpartum hemorrhage.

The great majority of embryos generated by somatic cell nuclear transfer (SCNT) display defined abnormal phenotypes after implantation, such as an increased likelihood of death and abnormal placentation. To gain better insight into the underlying mechanisms, we analyzed genome-wide gene expression profiles of day 6.5 postimplantation mouse embryos cloned from three different cell types (cumulus cells, neonatal Sertoli cells and fibroblasts). The embryos retrieved from the uteri were separated into embryonic (epiblast) and extraembryonic (extraembryonic ectoderm and ectoplacental cone) tissues and were subjected to gene microarray analysis. Genotype- and sex-matched embryos produced by in vitro fertilization were used as controls. Principal component analysis revealed that whereas the gene expression patterns in the embryonic tissues varied according to the donor cell type, those in extraembryonic tissues were relatively consistent across all groups. Within each group, the embryonic tissues had more differentially expressed genes (DEGs) (>2-fold vs. controls) than did the extraembryonic tissues (Pcloning efficiency using SCNT. PMID:24146866

Full Text Available Uterus transplantation has been considered as an alternative management modality in the last few years for adoption or gestational surrogacy for women with absence of uterus due to congenital or acquired reasons. Surrogacy is legal in only a few countries because of ethical, social and legal issues. Up to date, a total of 11 uterus transplantation cases have been reported in which uteri were harvested from ten live donors and one donor with brain death. After unsuccessful attempt of first uterus transplantation, many studies have been conducted in animals and these experimental models enabled our knowledge to increase on this topic. First experimental studies were performed in rodents; later uterus transplantation was accomplished in sheep, pigs and rabbits. Recently, researches in non-human primates have led the experience regarding transplantation technique and success to improve. In this review, we reviewed the experimental animal researches in the area of uterus transplantation and recent experience in humans.

Neuroendocrine tumors (neuroendokrine Tumoren) are rare entities. They can be found in all organs and show substantial biologic heterogeneity depending on involved organ, clinical symptoms and histopathologic morphology. Involvement of organs like larynx, cervix uteri, ovary, gallbladder, liver or kidney is extensively rare. The majority of neuroendokrine Tumoren are found in gastrointestinal tract and lung and are classified as neuroendokrine Tumoren of foregut (stomach, duodenum, pancreas, lung), midgut (jejunum, ileum, appendix, right side of the colon) and hindgut (left side of the colon, rectum). The role of imaging is to localize and delineate the primary tumor and to detect metastases. In the diagnosis of neuroendokrine Tumoren radiologic techniques like computed tomography (CT) and magnetic resonance imaging (MRI) are applied. In certain cases nuclear medicine techniques like somatostatin receptor scintigraphy (SRS) and positron emission tomography (PET) using radioactively labelled somatostatin analogues are used. The present article reviews characteristic imaging findings of neuroendokrine Tumoren of the gastrointestinal tract. (orig.)

Mutations in the Norrie disease pseudoglioma gene (NDP) are known to cause X-linked recessive Norrie disease. In addition, NDP mutations have been found in other vasoproliferative retinopathies such as familial exudative vitreoretinopathy, retinopathy of prematurity, and Coats disease, suggesting a role for Norrin in vascular development. Here we report that female mice homozygous for the Norrie disease pseudoglioma homolog (Ndph) knockout allele exhibit almost complete infertility, while heterozygous females and hemizygous males are fertile. Histological examinations and RNA in situ hybridization analyses revealed defects in vascular development and decidualization in pregnant Ndph-/- females from embryonic day 7 (E7) onwards, resulting in embryonic loss. Using RT-PCR analyses we also demonstrate, for the first time, the expression of Ndph in mouse uteri and deciduae as well as the expression of NDP in human placenta. Taken together, these data provide strong evidence for Norrin playing an important role in female reproductive tissues. Copyright 2005 Wiley-Liss, Inc

2013-01-01

Full Text Available Objectives. This study observes therapeutic efficacy of uterine artery embolization combined with MTX infusion which terminates cesarean scar pregnancy (CSP and induces three factors which probably relate to failure. Methods. Twenty-three CSP patients were treated with combined uterine artery MTX infusion and embolization. Among them six patients with severe hemorrhage were immediately treated with interventional operation. Clinical effects were estimated by symptoms, serum -hCG, ultrasound, and MR. Results. Interventional treatments were technologically successful in 22 patients except one. Immediate hemostasis was achieved in all 6 patients with massive colporrhagia. No occurrence of infection and uterine necrosis was observed, but 12 women suffered abdominal pains. Nineteen patients’ uteri were preserved, whereas four underwent hysterectomy eventually. Conclusions. Transcatheter arterial chemoembolization is effective to treat high-risk CSP in preference to hysterectomy. To achieve more successful outcomes, three factors should be highlighted: adequate MTX dosage, appropriate embolic material, and complete embolization of target arteries that supply blood to embryo in the scar.

Sporotrichosis is a subcutaneous mycosis caused by Sporothrix sp., a dimorphic fungus. Although the cutaneous form is the most frequent form, the ocular presentation has been increasingly diagnosed in epidemic areas. We describe three cases of ocular sporotrichosis with the involvement of the ocular adnexa due to autoinoculation without trauma with successful antifungal treatment. Patient 1: A 68-year-old woman presented with granulomatous conjunctivitis of the right eye with an ulcerated nodule on the right temporal region for 5 months. Patient 2: A 46-year-old woman with conjunctival hyperemia of the left eye with associated periorbital edema and erythema for the past 4 months was referred to the Dermatology Department due to an ulcerated nodule on the left malar region. Patient 3: A 14-year-old boy presented to the emergency department with inferior palpebral edema with a 5-day evolution. Specimens were obtained from the lesions of the three patients, and the cultures were positive for Sporothrix sp. The three cases were diagnosed as ocular sporotrichosis and were successfully treated with itraconazole (200-400 mg/d). Two of the three patients developed sequelae such as conjunctival fibrosis and symblepharon. We emphasize the importance of the ophthalmologist being familiar with the diagnosis and management of this rare and frequently misdiagnosed form of sporotrichosis.

Malignant mixed Mullerian tumour is a rare gynaecological tumour commonly presenting with vaginal bleeding, abdominal pain or mass in the uterine cavity, cervix or vagina. The neoplasms are commonly seen in postmenopausal women although it has been observed in younger women. Ovaries and the corpus of the uterus are commonly involved, whereas involvement of the cervix and vagina is rare. A 37 year-old Tanzania lady para 7 with a previous history of two genital polypectomies presented with history of recurrent vaginal mass which was associated with abnormal vaginal bleeding and foul smelling discharge. Vaginal examination revealed a prolapsed uterus with giant fungating cervical mass which was ulcerated, friable, and bled easily on touch. Impression was grade three uterine prolapse with infected cervical polyp/cervical sarcoma. Excision of the tumour through trans-vaginal hysterectomy was performed, no lymphadenopathy was found, no adnexa abnormalities, and no involvement of the vaginal wall. Histological diagnosis of Malignant mixed Mullerian tumour of the cervix was made. Patient recovery was unremarkable; however she was lost to follow up. The patient's mass was initially suspected to be prolapsed uterus with decubitus ulcer but the histological results were of a malignant condition. Lack of clear management guidelines for some rare mixed tumours remains a challenge for clinicians in low resource settings.

Ovarian Torsion in the Third Trimester of Pregnancy Leading to Iatrogenic Preterm Delivery

Full Text Available Ovarian torsion in the third trimester of pregnancy leading to a midline laparotomy and caesarean section for the delivery of a preterm baby is an uncommon event. As the woman is likely to present with nonspecific symptoms of lower abdominal pain, nausea, and vomiting, ovarian torsion can often be misdiagnosed as appendicitis or preterm labour. Treatment and the opportunity to preserve the tube and ovary may consequently be delayed. We report the case of a multiparous woman who had undergone two previous caesarean sections at term, presenting at 35 weeks of gestation with a presumptive diagnosis of acute appendicitis. Ultrasonography described a cystic lesion 6 × 3 cm in the right adnexa, potentially a degenerating fibroid or a torted right ovary. MRI of the pelvis was unable to provide further clarity. The patient was managed by midline laparotomy and simultaneous detorsion of the ovarian pedicle and ovarian cystectomy together with caesarean section of a preterm infant. This report describes that prompt recognition and ensuring intraoperative access can achieve a successful maternal and fetal outcome in this rare and difficult scenario. Furthermore, we would like to emphasise that the risk for a pregnant woman and her newborn could be reduced by earlier diagnosis and management of ovarian masses (Krishnan et al., 2011.

Systematic screening for skin, hair, and nail abnormalities in a large-scale knockout mouse program.

John P Sundberg

Full Text Available The International Knockout Mouse Consortium was formed in 2007 to inactivate ("knockout" all protein-coding genes in the mouse genome in embryonic stem cells. Production and characterization of these mice, now underway, has generated and phenotyped 3,100 strains with knockout alleles. Skin and adnexa diseases are best defined at the gross clinical level and by histopathology. Representative retired breeders had skin collected from the back, abdomen, eyelids, muzzle, ears, tail, and lower limbs including the nails. To date, 169 novel mutant lines were reviewed and of these, only one was found to have a relatively minor sebaceous gland abnormality associated with follicular dystrophy. The B6N(Cg-Far2tm2b(KOMPWtsi/2J strain, had lesions affecting sebaceous glands with what appeared to be a secondary follicular dystrophy. A second line, B6N(Cg-Ppp1r9btm1.1(KOMPVlcg/J, had follicular dystrophy limited to many but not all mystacial vibrissae in heterozygous but not homozygous mutant mice, suggesting that this was a nonspecific background lesion. We discuss potential reasons for the low frequency of skin and adnexal phenotypes in mice from this project in comparison to those seen in human Mendelian diseases, and suggest alternative approaches to identification of human disease-relevant models.

Full Text Available Aim. To evaluate eye drop instillation technique and to explore its determinants in glaucoma patients. Methods. One hundred and thirteen patients diagnosed with glaucoma and self-administering topical antiglaucoma eye drops for at least 1 month were evaluated. All patients instilled artificial tear solution in one eye as they would do at home. The whole process was evaluated by two study staff. A comprehensive score system associated with eye drop instillation techniques was used to quantify the instillation technique and explore its determinants such as demographic and clinical characteristics. Results. Half of the patients (48.67% finished the administration of eye drop on first attempt.1.7 eye drops were squeezed out on average. 43 patients (37.17% got contact with ocular surface or adnexa. Only 19.7% patients had eye drop instillation techniques being defined as well. 11 patients (9.7% had prior instruction regarding using eye drops, while only 4 patients knew to occlude the tear duct by pressing the dacryocyst area. Older age and worse visual acuity were found to be independent risk factors for worse instillation technique. Conclusions. Eye drop instillation technique in glaucoma patients deserves great attention from eye care practitioners during their lifelong follow-up, especially those aged older and have worse visual acuity.

Full Text Available Objective: Retinoblastoma is the most common malignancy of the eye and ocular adnexa in the Philippines. It is curable when treated early, but delay in enucleation is common due to the parental refusal of surgery for varied reasons. The aim of this study is to identify the psychosocial barriers and facilitating factors for accepting versus refusing enucleation as treatment for retinoblastoma. Methods: This is a cross-sectional descriptive study utilizing structured interviews and a questionnaire. It was conducted at the Retinoblastoma Clinic of the Philippine General Hospital. A questionnaire using the Likert scale was constructed after performing key informant interviews and focus group discussions. It was pretested and revised before parents of patients with retinoblastoma were invited to participate in the study. Descriptive statistics, quantitative item analyses using inter-item correlations and item-total correlations was performed. Results: Factors that correlate with refusal to enucleate are the beliefs that cancer is a fatal illness, the fear of unacceptable esthetic outcome of the surgery, and the cost of treatment. Favorable factors include value of life, high regard for the opinion of medical practitioners, and appreciation of the efficacy of treatment. Conclusions: There are several favorable factors and barriers that health practitioners must consider in facilitating parental decision-making toward enucleation for retinoblastoma.

The purpose of this article is to help the practitioner ensure early diagnosis and response to emergencies in the first trimester by reviewing anatomy of the developing embryo, highlighting the sonographic appearance of common first-trimester emergencies, and discussing key management pathways for treating emergent cases. First-trimester fetal development is a stepwise process that can be challenging to evaluate in the emergency department (ED) setting. This is due, in part, to the complex anatomy of early pregnancy, subtlety of the sonographic findings, and the fact that fewer than half of patients with ectopic pregnancy present with the classic clinical findings of a positive pregnancy test, vaginal bleeding, pelvic pain, and tender adnexa. Ultrasound (US) has been the primary approach to diagnostic imaging of first-trimester emergencies, with magnetic resonance imaging (MRI) and computed tomography (CT) playing a supportive role in a small minority of cases. Familiarity with the sonographic findings diagnostic of and suspicious for early pregnancy failure, ectopic pregnancy, retained products of conception, gestational trophoblastic disease, failed intrauterine devices, and complications associated with assisted reproductive technology (ART) is critical for any emergency radiologist. Evaluation of first-trimester emergencies is challenging, and knowledge of key imaging findings and familiarity with management pathways are needed to ensure early diagnosis and response.

Dermatology in the Darwin anniversary. Part 1: Evolution of the integument.

Schempp, Christoph; Emde, Matthias; Wölfle, Ute

2009-09-01

The present review highlights the development of the integument and its adnexa from the primitive metazoans to man. The different stages of development represent independent, partially convergent evolutions rather than a continuous evolutionary line. The epidermis of the invertebrates (sponges, cnidaria, worms, echinoderms and arthropods) always consists of one layer of pluripotent cells. The barrier function of the integument at this level is achieved with physico-chemical barriers, toxin production, fortification of the epidermis in the form of a cuticula, a syncytium or a neodermis. The lower vertebrates (cyclostoma, fishes and amphibians) have a stratified epidermis harboring many secretory cells. In terrestrial amphibians the outermost cell layer of the epidermis is cornified, and the secretory cells are relocated in the dermis. Terminal differentiation and cornification of the epidermis in the birds and mammals result in a more uniform shape of the epithelium. Stem cells are now restricted to some basal regions of the epithelium. In the mammals the glands are located in the deeper layers of the skin. In contrast to other vertebrate integuments the human skin does not possess specialized structures such as feathers, scales or coats. However, waiving specialization allows for unique universality of the human skin compared to other vertebrates.

Full Text Available A 38-year-old female with systemic lupus erythematosus presented with abdominal pain, diarrhea and iron-deficient anemia. Computed tomogram showed a 2x4 cm inhomogeneous lesion of the right adnexa. An unusual mass was identified extending from the appendiceal orifice at colonoscopy, and an 8 cm tubular appendix, apparently prolapsed into the cecum, was identified at celiotomy. An appendectomy with cecectomy was performed. On cut section, mucin was extruded from the lumen of the appendix. A mucinous neoplasm of the appendix with mucinous dissection to the serosal surface was reported at the time of frozen section. No gross ovarian pathology or peritoneal implants were noted. Cystadenoma with associated mucocele formation was verified by permanent histology. Mucocele of the vermiform appendix is a rare condition associated with neoplastic transformation in approximately 75% of all cases. Benign mucinous cystadenoma of the appendix should be differentiated from cystadenocarcinoma by frozen section at the time of celiotomy to ensure appropriate treatment. While systemic lupus erythematosus can lead to cutaneous mucinosis, an association with mucinous cystadenoma of the appendix has not been previously reported. Surveillance for metachronous colonic neoplasms is warranted in patients diagnosed with a mucinous neoplasm of the appendix.

In a controlled field trial, 178 dairy cows with chronic endometritis and at least 21 days in lactation were randomly assigned to four different treatment groups: prostaglandin F2alpha intramuscularly (PG, 5 mg dinoprost (5 ml Dinolytic), n = 51), intrauterine antibiotics (AB; 400 mg ampicillin + 800 oxacillin (20 ml Totocillin), n = 49), intrauterine antiseptics (AS; 100 ml 4% Lotagen, n = 50); control (C, no initial treatment, n = 28). Before treatment, uterine swabs for bacteriologic examination and blood samples for determination of serum progesterone concentrations were collected. Two weeks following the first treatment, cows were reexamined. In case no clinical cure was diagnosed, treatment was repeated and control cows were treated for the first time with one of the three treatments mentioned above. The four treatment groups did not differ with respect to the clinical cure or reproductive performance. Therefore, factors that might have an influence on clinical cure and fertility were evaluated. With increasing duration of lactation, the clinical cure after a single treatment increased significantly over all treatment groups from 59.5% (treatment before day 42 postpartum) to 79.6% (treatment following day 42 postpartum) (P conception rate and a lower pregnancy index were obtained when the treatment was performed following day 42 postpartum (P size had a negative effect on clinical cure over all groups (first treatment clinical cure: 68.2% (small uteri) vs 44.4% (large uteri); P 0.05). Isolation of Arcanobacterium (A.) pyogenes negatively influenced first treatment clinical cure over all treatment groups (79.0% vs 31.5%) and within treatment groups (P conception increased compared with the other treatment groups, when A. pyogenes was detected. Isolation of unspecific bacteria and the presence or absence of a corpus luteum only had minor effects over all and within the PG, AS and C group. Within the AB group, presence of luteal tissue was connected with a

How long is the allowable warm ischemic time of the uterus and what morphological and biochemical changes are caused by uterine ischemia/reperfusion injury in cynomolgus macaques? Warm ischemia in the uterus of cynomolgus macaques is tolerated for up to 4 h and reperfusion after uterine ischemia caused no further morphological and biochemical changes. Uterus transplantation is a potential option for women with uterine factor infertility. The allowable warm ischemic time and ischemia/reperfusion injury of the uterus in humans and non-human primates is unknown. This experimental study included 18 female cynomolgus macaques with periodic menstruation. Animals were divided into six groups of three monkeys each: a control group and groups with uterine ischemia for 0.5, 1, 2, 4 and 8 h. Biopsies of uterine tissues were performed before blood flow blockage, after each blockage time, and after reperfusion for 3 h. Blood sampling was performed after each blockage time, and after reperfusion for 5, 15 and 30 min for measurement of biochemical data. Resumption of menstruation was monitored after the surgical procedure. Morphological, physiological and biochemical changes after ischemia and reperfusion were evaluated. Mild muscle degeneration and zonal degeneration were observed in all animals subjected to warm ischemia for 4 or 8 h, but there were no marked differences in the appearance of specimens immediately after ischemia and after reperfusion for 3 h in animals subjected to 4 or 8 h of warm ischemia. There were no significant changes in any biochemical parameters at any time point in each group. Periodical menstruation resumed in all animals with warm ischemia up to 4 h, but did not recover in animals with warm ischemia for 8 h with atrophic uteri. Warm ischemia in actual transplantation was not exactly mimicked in this study because uteri were not perfused, cooled, transplanted or reanastomosed with vessels. Results in non-human primates cannot always be extrapolated to

What is the role of the endocannabinoid system (eCS) on the lipopolysaccharide (LPS) effects on uterine explants from 7-day pregnant mice in a murine model of endotoxin-induced miscarriage? We found evidence for cannabinoid receptor type2 (CB2) involvement in LPS-induced increased prostaglandin-F2α (PGF2α) synthesis and diminished cyclic adenosine monophosphate (cAMP) intracellular content in uterine explants from early pregnant mice. Genital tract infections by Gram-negative bacteria are a common complication of human pregnancy that results in an increased risk of pregnancy loss. LPS, the main component of the Gram-negative bacterial wall, elicits a strong maternal inflammatory response that results in embryotoxicity and embryo resorption in a murine model endotoxin-induced early pregnancy loss. We have previously shown that the eCS mediates the embryotoxic effects of LPS, mainly via CB1 receptor activation. An in vitro study of mice uterine explants was performed to investigate the eCS in mediating the effects of LPS on PGF2α production and cAMP intracellular content. Eight to 12-week-old virgin female BALB/c or CD1 (wild-type [WT] or CB1-knockout [CB1-KO]) mice were paired with 8- to 12-week-old BALB/c or CD1 (WT or CB1-KO) males, respectively. On day 7 of pregnancy, BALB/c, CD1 WT or CD1 CB1-KO mice were euthanized, the uteri were excised, implantation sites were removed and the uterine tissues were separated from decidual and embryo tissues. Uterine explants were cultured and exposed for an appropriate amount of time to different pharmacological treatments. The tissues were then collected for cAMP assay and PGF2α content determination by radioimmunoassay. In vitro treatment of uteri explants from 7-day pregnant BALB/c or CD1 (WT or CB1-KO) mice with LPS induced an increased production of PGF2α (P Investigaciones Científicas y Técnicas (PIP 2012/0061).

Mercy Nyamewaa Asiedu

Full Text Available Cervical cancer screening usually requires use of a speculum to provide a clear view of the cervix. The speculum is one potential barrier to screening due to fear of pain, discomfort and embarrassment. The aim of this paper is to present and demonstrate the feasibility of a tampon-sized inserter and the POCkeT Colposcope, a miniature pen sized-colposcope, for comfortable, speculum-free and potentially self-colposcopy.We explored different designs using 3D computer-aided design (CAD software and performed mechanical testing simulations on each. Designs were rapid prototyped and tested using a custom vaginal phantom across a range of vaginal pressures and uterine tilts to select an optimal design. Two final designs were tested with fifteen volunteers to assess cervix visualization, comfort and usability compared to the speculum and the optimal design, the curved-tip inserter, was selected for testing in volunteers.We present a vaginal inserter as an alternative to the standard speculum for use with the POCkeT Colposcope. The device has a slim tubular body with a funnel-like curved tip measuring approximately 2.5 cm in diameter. The inserter has a channel through which a 2 megapixel (MP mini camera with LED illumination fits to enable image capture. Mechanical finite element testing simulations with an applied pressure of 15 cm H2O indicated a high factor of safety (90.9 for the inserter. Testing of the device with a custom vaginal phantom, across a range of supine vaginal pressures and uterine tilts (retroverted, anteverted and sideverted, demonstrated image capture with a visual area comparable to the speculum for a normal/axial positioned uteri and significantly better than the speculum for anteverted and sideverted uteri (p<0.00001. Volunteer studies with self-insertion and physician-assisted cervix image capture showed adequate cervix visualization for 83% of patients. In addition, questionnaire responses from volunteers indicated a 92

Full Text Available Trial of labor after cesarean section can be a choice on maternity with cesarean history. The successful trial of labor is then called vaginal birth after a cesarean (VBAC. The failure on VBAC is often caused by hypotonic uterine inertia. Oxytocin infusion augmentation is not a contraindication; it is a solution for increasing success on VBAC with requisite continuing observation. The aim of this research was to determine the successful differences of VBAC on hypotonic uterine inertia with and without oxytocin augmentation. This research was an experimental study on randomized clinical trial, using 40 patients with history of cesarean section at Dr. Hasan Sadikin Hospital and two satellite hospitals (Sumedang and Astana Anyar during March–May 2009 which fulfilled inclusion criteria divided into two groups; the group using oxytocin infusion and the group without oxytocin infusion. The patients’ characteristic, the success on VBAC and the maternal complication also neonatal condition were noted as encode. Chi-square test was used for statistical analysis. There was no statistical significant difference of success between the group used oxytocin infusion (80% and the group without using oxytocin infusion (60% with p>0.05 (p=0.168, but using confidence interval 95% showed the successful on VBAC with oxytocin infusion was greater 1.71 (0.72–4.06. The maternity and neonatal complication on two groups did not indicate a significant difference. In conclusion, using oxytocin infusion on hypotonic uterine inertia can increase the success on VBAC

the bladder must not be separated first, but instead, an assessment must be made to determine if the bladder trigone is involved. (4) Rectal cancer with invasion of the sacrum: sacral invasion below S3 can be resected. The proximal end of the rectum to the point where it joins the sacrum is freed, and the rectum is severed. A permanent colostomy is made at the proximal end, while a h-shaped incision is made in the sacrum. The sacrum is then resected along pre-determined resection lines. (5) Rectal cancer with invasion of the uterus, adnexa, vagina, or prostate and seminal vesicles: it is usually observed in low rectal cancer. For unilateral ovarian involvement, combined resection of the bilateral adnexa should be performed. For vaginal involvement, combined resection of the vagina should be performed. For prostatic involvement, partial resection of the prostate can be performed. In general, when facing relatively complicated advanced or locally advanced colorectal cancer, clinical surgeons must adopt a positive attitude and strive zealously against the odds. With the support of multi-disciplinary treatment, the option of surgery must not be hastily abandoned in order to increase the survival chances of patients.

Isolation and characterization of Wharton’s jelly-derived multipotent mesenchymal stromal cells obtained from bovine umbilical cord and maintained in a defined serum-free three-dimensional system

Full Text Available Abstract Background The possibility for isolating bovine mesenchymal multipotent cells (MSCs from fetal adnexa is an interesting prospect because of the potential for these cells to be used for biotechnological applications. Bone marrow and adipose tissue are the most common sources of MSCs derived from adult animals. However, little knowledge exists about the characteristics of these progenitors cells in the bovine species. Traditionally most cell cultures are developed in two dimensional (2D environments. In mammalian tissue, cells connect not only to each other, but also support structures called the extracellular matrix (ECM. The three-dimensional (3D cultures may play a potential role in cell biotechnology, especially in tissue therapy. In this study, bovine-derived umbilical cord Wharton’s jelly (UC-WJ cells were isolated, characterized and maintained under 3D-free serum condition as an alternative of stem cell source for future cell banking. Results Bovine-derived UC-WJ cells, collected individually from 5 different umbilical cords sources, were successfully cultured under serum-free conditions and were capable to support 60 consecutive passages using commercial Stemline® mesenchymal stem cells expansion medium. Moreover, the UC-WJ cells were differentiated into osteocytes, chondrocytes, adipocytes and neural-like cells and cultured separately. Additionally, the genes that are considered important embryonic, POU5F1 and ITSN1, and mesenchymal cell markers, CD105+, CD29+, CD73+ and CD90+ in MSCs were also expressed in five bovine-derived UC-WJ cultures. Morphology of proliferating cells typically appeared fibroblast-like spindle shape presenting the same viability and number. These characteristics were not affected during passages. There were 60 chromosomes at the metaphase, with acrocentric morphology and intense telomerase activity. Moreover, the proliferative capacity of T cells in response to a mitogen stimulus was suppressed when

Downregulation of the non-integrin laminin receptor reduces cellular viability by inducing apoptosis in lung and cervical cancer cells.

Directory of Open Access Journals (Sweden)

Kiashanee Moodley

Full Text Available The non-integrin laminin receptor, here designated the 37-kDa/67-kDa laminin receptor (LRP/LR, is involved in many physiologically relevant processes, as well as numerous pathological conditions. The overexpression of LRP/LR on various cancerous cell lines plays critical roles in tumour metastasis and angiogenesis. This study investigated whether LRP/LR is implicated in the maintenance of cellular viability in lung and cervical cancer cell lines. Here we show a significant reduction in cellular viability in the aforementioned cell lines as a result of the siRNA-mediated downregulation of LRP. This reduction in cellular viability is due to increased apoptotic processes, reflected by the loss of nuclear integrity and the significant increase in the activity of caspase-3. These results indicate that LRP/LR is involved in the maintenance of cellular viability in tumorigenic lung and cervix uteri cells through the blockage of apoptosis. Knockdown of LRP/LR by siRNA might represent an alternative therapeutic strategy for the treatment of lung and cervical cancer.

1980-01-01

Radiolabeling of mammalian spermatozoa with 131 I, 67 Ga, 111 In, and /sup 99m/Tc was investigated. Spermatozoa were labeled with /sup 99m/Tc for in vivo studies because of a high labeling yield (70 to 90%) combined with the lack of impairment of sperm motility. Ovariectomized sheep were brought into estrus by sequential administration of progesterone and estradiol cyprionate. Sheep were necropsied up to 6 hours after insemination with /sup 99m/Tc-labeled ram sperm and their reproductive tracts were resected and examined with a rectilinear scanner. Radioactivity was clearly observed in the fallopian tubes, with larger amounts in the vaginas, cervices, and uteri. In contrast, when /sup 99m/Tc-spermatozoa were replaced with /sup 99m/TcO 4 - , much less radioactivity remained in the reproductive tract at resection and this was evenly distributed. Some label left the /sup 99m/Tc-spermatozoa in vivo, but radioactivity remained on the cells long enough to consider attempting to monitor sperm transport in vivo in a suitable species

ABSTRACT Background: Cervix uteri cancer is the 4th most common cancer among women worldwide and the second most frequent cancer in women under 45 years old in Spain. We aimed to describe the burden of hospital admissions by malignant neoplasia (MN) and in situ carcinoma (ISC) of the cervix in Spain from 2003 to 2014, a 12-year period that included the first years after introduction of an HPV vaccination program. Methods: This epidemiological study reviewed data from the Ministry of Health National Surveillance System, which includes more than 98% of Spanish hospitals. Hospitalization rate, mortality rate, and case fatality rates were calculated per year and age group. Results: We found 74,933 hospitalizations due to MN and ISC of the cervix. The average age at hospitalization increased significantly during the study period. The average length of hospital stay decreased significantly (pcancer prevention measures, and changes in disease management. Further research is needed to confirm the cause. This information could contribute to further evaluations of the impact and cost effectiveness analysis of HPV vaccination in Spain. PMID:29206085

Amino acids (AAs) are crucial for the developing conceptus prior to implantation. To provide insights into the requirements of the bovine embryo, we determined the AA composition of the uterine fluid. At days 12, 15, and 18 post-estrus, the uteri of synchronized pregnant and non-pregnant Simmental heifers were flushed for the analysis of 41 AAs and their derivatives by liquid chromatography-tandem mass spectrometry. The ipsilateral endometrium was sampled for quantitative PCR. In addition to a pregnancy-dependent increase of the essential AAs (P<0.01), we detected elevated concentrations for most non-essential proteinogenic AAs. Histidine (His) and the expression of the His/peptide transporter solute carrier 15A3 (SLC15A3) were significantly increased at day 18 of pregnancy in vivo. In addition, SLC15A3 was predominantly stimulated by trophoblast-derived interferon-τ in stroma cells of an in vitro co-culture model of endometrial cells. Our results show an increased concentration of AAs most likely to optimally provide the elongating pre-attachment conceptus with nutrients.

A Gata2-Dependent Transcription Network Regulates Uterine Progesterone Responsiveness and Endometrial Function

Full Text Available Altered progesterone responsiveness leads to female infertility and cancer, but underlying mechanisms remain unclear. Mice with uterine-specific ablation of GATA binding protein 2 (Gata2 are infertile, showing failures in embryo implantation, endometrial decidualization, and uninhibited estrogen signaling. Gata2 deficiency results in reduced progesterone receptor (PGR expression and attenuated progesterone signaling, as evidenced by genome-wide expression profiling and chromatin immunoprecipitation. GATA2 not only occupies at and promotes expression of the Pgr gene but also regulates downstream progesterone responsive genes in conjunction with the PGR. Additionally, Gata2 knockout uteri exhibit abnormal luminal epithelia with ectopic TRP63 expressing squamous cells and a cancer-related molecular profile in a progesterone-independent manner. Lastly, we found a conserved GATA2-PGR regulatory network in both human and mice based on gene signature and path analyses using gene expression profiles of human endometrial tissues. In conclusion, uterine Gata2 regulates a key regulatory network of gene expression for progesterone signaling at the early pregnancy stage.

Female mice were injected, every 30 days for 5 months, with a long-acting formulation of microcapsules liberating 2.5 micrograms D-Trp-6-LHRH/day. The control group was injected with vehicle only. At 30 days after the last injection mice were killed, ovaries, uteri and adrenals were weighed and fixed in formalin for histological studies. LH and oestradiol concentrations were measured by RIA. In the D-Trp-6-LHRH-treated group, the weights of the ovaries and uterus (P less than 0.01 and P less than 0.05, respectively), and LH and oestradiol values (P less than 0.02 and P less than 0.01, respectively) were reduced compared to controls. Histologically, the ovaries contained a large number of degenerated, atretic follicles, and corpora lutea had almost completely disappeared. These results indicate, contrary to the prevailing opinion, that mice are sensitive to inhibitory effects of LHRH agonists and that a suppression of the pituitary-gonadal axis can be obtained with long-term administration of D-Trp-6-LHRH microcapsules.

In order to know if it is possible to objectively decide the extent of infiltration of female genital malignant tumors into parametrium by using 111 In-bleomycin scintigraphy, a fundamental and clinical investigation was made. The radiochemical purity and stability of 111 In-BLM were comparatively unchangeable. When this complex was kept at room temperature for a week, there was not more than 2% of the free 111 In. As to blood clearance, when the blood radioactivity of 111 In-BLM 5 minutes after the injection was counted as 100%, about 80% of the radioactivity was cleared from the blood in 48 hours. Over 50% of the radioactivity was excreted into the urine in 48 hours. Of 29 cases of female genital malignant tumors, 23 cases (79%) showed positive images. Therefore 111 In-BLM was found to be one of the suitable radiopharmaceuticals for the diagnosis of female genital malignant tumors. 111 In-BLM scintigraphy was of great use for deciding the extent of the invasion of carcinoma cervicis uteri into parametrium and for the search of metastasis.

Physical exercise is known to be a stressor stimulus that leads to reproductive disruption. The aim of this study was to evaluate the effect of forced swimming on the uterus and ovaries in mice. Adult mice (N=24) were divided into the following three groups: A, control; B, swimming in water (10 o C); and C, swimming in water (23 o C). Swimmers swam for 5 min daily for 5 consecutive days/ wk during 2 wks. An enzyme linked immunosorbent assay was used to determine serum estradiol, follicle stimulating hormone (FSH) and testosterone levels. Immunohistochemistry was performed to study apoptotic cells or estrogen receptor (ER) expression in uterine epithelial cells and ovaries. ANOVA was used for statistical analysis. Swimming in both groups reduced the serum FSH and estradiol levels (pForced swimming of 2 wks duration reduces the serum levels of FSH and estradiol without having effects on apoptosis in the ovaries or uteri of mice. Over a long period of time, forced swimming may have an adverse effect on fertility.

Full Text Available Abstract Background The aim of this study was to identify factors associated with cancer screening practices and with general attitudes toward cancer screening in a general population. Methods Mailed survey of 30–60 year old residents of Geneva, Switzerland, that included questions about screening for five cancers (breast, cervix uteri, prostate, colon, skin in the past 3 years, attitudes toward screening, health care use, preventive behaviours and socio-demographic characteristics. Cancer screening practice was dichotomised as having done at least one screening test in the past 3 years versus none. Results The survey response rate was 49.3% (2301/4670. More women than men had had at least one cancer screening test in the past 3 years (83.2% vs 34.5%, p Conclusion Attitudes play an important role in cancer screening practices among middle-aged adults in the general population, independent of demographic variables (age and sex that determine in part screening recommendations. Negative attitudes were the most frequent among men and the most socio-economically disadvantaged. The moderate participation rate raises the possibility of selection bias.

To determine whether central catecholaminergic pathways are involved in the neural contral of gonadotrophin secretion, they were interrupted at the hypothalamic level by microinjections of 6-hydroxydopamine (6-OHDA). The effects on ovulation, estral cycle and ovarian and uterine histology were studied. Microinjections of 50 mug of 6-OHDA hydrobromyde were made bilaterally into the anterolateral hypothalamus in a group of rats. Another group was injected with 25 mug of 6-OHDA, while a control group recieved an equivalent volume (5 mul) of saline with ascorbic acid. Animals injected with 50 mug of 6-OHDA showed blockade of ovulation, vaginal cytology characteristics of persistent estrous, polyfollicular ovaries and enlarged uteri with hypertrophic endometrial glands. In the group injected with 25 mug, similiar effects were demonstrated, but the number of affected animals was smaller than that in the 50 mug group. Control animals dit not show modifications, either in estral cycle or in ovarian and uterine histology. These results suggest that 6-OHDA injected into the anterolateral hypothalmus interferes with catecholaminergic pathways that participate in the neural control of ovulation.

Vaginal Cuff Dehiscence with Small Bowel Evisceration 14 Months after Total Abdominal Hysterectomy

Nida Jareemit, M.D.

2017-11-01

Full Text Available Introduction: Vaginal cuff dehiscence is a rare complication following hysterectomy. The condition coexisting with intraabdominal organ evisceration occurs even rarer. Nevertheless this should not be neglected owing to high morbidity and mortality. Case presentation: The reported case is a 48-year-old widow presenting with vaginal cuff dehiscence and small bowel evisceration after undergoing a total abdominal hysterectomy (TAH in the past 14 months due to myoma uteri. She denied having a history of sexual intercourse after the operation. The exposed bowel, 60 cm in length, appeared viable and no peritoneal sign was observed. There was a vaginal cuff defect approximately 3 cm in length. An exploratory laparotomy was then carried out. Eviscerated bowel was reduced back in the abdominal cavity and the vaginal cuff defect was repaired. No complications such as recurrent dehiscence were observed during one year follow-up. Conclusion: To minimize the incidence of vaginal cuff dehiscence after hysterectomy, surgical techniques should be of concern. Patient instructions, including delaying sexual intercourse and avoiding all possible causes of increased intra-abdominal pressure should be provided postoperatively.

Purpose: To demonstrate that margins of each pelvic chain may be derived by verifying the bony and soft tissue structures around abnormal nodes on computed tomography (CT) slices. Methods and Materials: Twenty consecutive patients (16 males, 4 females; mean age, 66 years; range, 43-80 years) with radiologic diagnosis of nodal involvement by histologically proved cervix carcinoma (two), rectum carcinoma (three), prostate carcinoma (four), lymphoma (five), penis carcinoma (one), corpus uteri carcinoma (one), bladder carcinoma (two), cutis tumor (one), and soft-tissue sarcoma (one) were retrospectively reviewed. One hundred CT scans showing 85 enlarged pelvic nodes were reviewed by two radiation oncologists (M.P., S.B.), and two radiologists (C.P., G.A.). Results: The more proximal structures to each enlarged node or group of nodes were thus recorded in a clockwise direction. Conclusion: According to their frequency and visibility, craniocaudal, anterior, lateral, posterior and medial margins of common iliac, external and internal iliac nodal chains, obturator and pudendal nodes, and deep and superficial inguinal nodes were derived from CT observations

We are currently faced with a progressive delay in the age at which women conceive for the first time. This raises the possibility of the appearance of gynecologic disorders that may affect fertility, including neoplasms of the ovary. Fertility-sparing surgery is defined as the preservation of ovarian tissue in one or both adnexa and/or the uterus. Borderline ovarian tumor should be treated with conservative surgery. Salpingo-oophorectomy, or even ovarian cystectomy, are the procedures of choice, with recurrence rates of 2-3% and up to 20% if a simple cystectomy is performed. Cystectomy is indicated in patients with bilateral borderline tumors or in patients with a residual ovary. Borderline tumors with invasive peritoneal implants behave as an invasive cancer in 10-30% of cases with a survival rate of 10-66% compared with 100% in borderline tumors without invasive implants. Prophylactic oophorectomy is recommended when desire of conception has been accomplished. Conservative surgery in invasive epithelial ovarian cancer is limited to Stage IA, grade 1 tumor, and in some highly selected grade 2 tumors of serous, mucinous or endometrioid type, well-encapsulated and free of adhesions. The standard oncological surgical procedure with preservation of the uterus and normal appearing ovary is recommended. This includes salpingo-oophorectomy, excision of any suspicious peritoneal lesion, multiple peritoneal biopsies, appendectomy (particularly in mucinous tumors), and pelvic and paraaortic lymphadenectomy.

Transvaginal(TV) sonography uses high-frequency transducer and allows access to the uterus and adnexa, provides better resolution and more accurate diagnosis of ectopic pregnancy. To determine the value and the utility of TV sonography for a suspected ectopic pregnancy, we studied 56 women during 4 months from January to April 1989. Of 56 patients 46 had an surgically confirmed ectopic pregnancy, 5 had not an ectopic pregnancy and 5 had not follow up. TV sonography provides definite sonographic diagnosis of ectopic pregnancy including an extrauterine gestational sac 34 cases(74%), extrauterine embryo 9 caes(19.7%), hematosalpinx 10 cases(21.7%). Overall adnexal mass was detected in 38 cases(82.6%) at initial TV sonography and in 44 cases(95.6%) at follow up TV sonography. Additional findings were uterine decidual reaction 19 cases(41.3%), pseudo G-sac 4 cases(8.7%), cul-de-sac fluid 42 cases(91.2%). Follow-up TV sonography showed newly developed or growing adnexal mass in 8 among 9 cases. False positive 5 cases were two ovarian cysts, one incomplete abortion, two parametrial thickening due to previous ectopic pregnancy and salpingectomy. TV sonography may improve the govality of patient management by early diagnosis and early surgical treatment, so may preserve fertility. In conclusion, we may suggest that TV sonography is an integral part of diagnostic modality in suspected ectopic pregnancy.

Autologous skin cell suspensions have been used for wound healing in patients with burns and against normal pigmentation in vitiligo. To separate cells and the extracellular matrix from skin tissue, most researchers use enzymatic digestion. Therefore, this process is difficult to perform during a routine surgical procedure. We aimed to prepare a suspension of noncultured autologous skin cells (NCSCs) using a tissue homogenizer as a new method instead of harsh biochemical reagents. The potential clinical applicability of NCSCs was analyzed using a nude-rat model of burn healing. After optimization of the homogenizer settings, cell viability ranged from 52 to 89%. Scanning electron microscopy showed evidence of keratinocyte-like cell morphology, and several growth factors, including epidermal growth factor and basic fibroblast growth factor, were present in the NCSCs. The rat model revealed that NCSCs accelerated skin regeneration. NCSCs could be generated using a tissue homogenizer for enhancement of wound healing in vivo. In the NCSC group of wounds, on day 7 of epithelialization, granulation was observed, whereas on day 14, there was a significant increase in skin adnexa regeneration as compared to the control group (PBS treatment; p study suggests that the proposed process is rapid and does not require the use of biochemical agents. Thus, we recommend a combination of surgical treatment with the new therapy for a burn as an effective method.

The aim of this paper is to explore the consequences of demographic ageing on healthcare demand in Slovenia for primary care, secondary care, hospital day-care treatments, and hospitalisations. In the paper, we develop a model for making projections of the total number of treatments using the age-group projection method with the scenario approach. The model allows the number of treatments to be observed with respect to medical services, age groups and main disease groups. The results are presented for the cross-section years 2015, 2025 and 2035. The smallest increase in the number of treatments occurs in primary care, a larger one for secondary care, and the largest for hospital day-care services and hospitalisations (up to 29.9%). The structure of demand will also change. Demand for healthcare services for children and infants will decrease while demand for diseases associated with older age groups will increase, particularly for diseases of the circulatory system, eye and adnexa, and diseases of the blood and blood-forming organs. The results presented in this paper can help improve understanding of similar processes in other countries for total healthcare demand and for changes in the structure of demand. The results show that the healthcare system in Slovenia will face a major additional burden in the next 20 years. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Tubo-ovarian actinomycosis.

1981-01-01

Full Text Available Actinomycotic infection of the female genital tract is rare. Actinomycosis is a chronic suppurative granulomatous infection that is characterized by formation of abscesses, multiple draining sinuses and appearance of tangled mycelial masses or granules in the discharges and tissue sections. 2 cases of tubo-ovarian actinomycosis are reported. The 1st case presented clinical with gastrointestinal symptoms and a ventral scar hernia following an operation for a non-healing abdominal wound 6 months earlier. The 2nd case sought medical attention for backache and leucorrhea of 4 years′ duration. Exploratory laparotomy in the 1st case revealed tubo-ovarian masses; the vermiform appendix was not traceable. The uterine cavity in the 2nd case harbored a wooden stick. Direct extension from established ileocacal actinomycosis was believed to involve the female genital adnexae in the past. Association of tubo-ovarian actinomycosis with the presence of a foreign body in the female genital tract has been reported sporadically in the literature, yet an increase in the incidence may be expected because of the frequent use of intrauterine contraceptive devices in recent times. It is suggested that in women presenting clinically with vague abdominal symptoms, backache and discharge, actinomycosis should be considered and ruled out with the help of cytologic and proper microbial culture methods. Once the diagnosis is established, the infection can be treated with good results with penicillin.

Since human papillomavirus (HPV) is the central causal factor in cervical cancer, understanding the epidemiology of this infection constitutes an important step towards development of strategies for prevention. Six hundred and fifty seven cervical samples were tested for HPV using PCR with consensus primers (MY09/MY11), by genotyping (restriction and sequencing analyses) and by cervical cytology, from women who attended a Health Examination Center of the French social security. Women with no cervical smear as well as women with cytological abnormalities within the last 3 years were recruited. HPV DNA was detected in 7.3% of the women (5.3% for high-risk, 2.4% for low-risk, and 0.5% for unknown risk types) including 6 (0.9%) mixed infections. Fifteen different genotypes were detected, of which genotypes 16 (22.2%), 58 (13.0%), 18 (11.1%), 30 (9.2%), and 33 (9.2%) were the most prevalent. In age group 17-25 years, we found the highest frequencies for both any (22.1%) and high-risk (14.7%) HPV, and prevalences gradually decreased with age. 5.2% of low-grade squamous intraepithelial lesion, 0.3% of high-grade squamous intraepithelial lesion, and 1.2% of atypical squamous cells of undetermined significance were found. The frequencies of high risk and all HPV types were significantly higher in squamous intraepithelial lesions than in those with normal and reactive/reparative changes (P < 0.0001). The prevalence of high-risk HPV in the atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion group (28.6%) was significantly higher than in the normal and reactive/reparative changes groups (3.4%) (P < 0.0001). HPV detection was associated with younger age, single marital and non-pregnant status (P < 0.0001), premenopausal status (P = 0.0004), and contraception (P = 0.0008). Marital status (OR 4.5; 95% CI = 2.3-9.0) and tobacco consumption (OR 3.0; 95% CI = 1.6-5.7) were predictive independent factors of HPV infection. The French system of Health Examination Centers might be of interest for following women regularly, especially those with a low socioeconomic status. Copyright 2004 Wiley-Liss, Inc.

The cancer stem cell (CSC) paradigm is one possible way to understand the genesis of cancer, and cervical cancer in particular. We quantified and enriched ALDH1(+) cells within cervical cancer cell lines and subsequently characterized their phenotypical and functional properties like invasion capacity and epithelial-mesenchymal transition (EMT). ALDH1 expression in spheroid-derived cells (SDC) and the parental monolayer-derived cell (MDC) line was compared by flow-cytometry. Invasion capability was evaluated by Matrigel assay and expression of EMT-related genes Twist 1, Twist 2, Snail 1, Snail 2, Vimentin and E-cadherin by real-time PCR. ALDH1 expression was significantly higher in SDC. ALDH1(+) cells showed increased colony-formation. SDC expressed lower levels of E-cadherin and elevated levels of Twist 1, Twist 2, Snail 1, Snail 2 and Vimentin compared to MDC. Cervical cancer cell lines harbor potential CSC, characterized by ALDH1 expression as well as properties like invasiveness, colony-forming ability, and EMT. CSC can be enriched by anchorage-independent culture techniques, which may be important for the investigation of their contribution to therapy resistance, tumor recurrence and metastasis.

To observe the effect of Cuichan Zhusheng Decoction (CZD) on cervical maturation factors. Ninety women with full-term pregnancy and indication for labor inducing were assigned to three groups equally. The treated group was treated by water decoction of CZD, one dose (300 mL) daily, taken orally in the morning 30 min before breakfast, for successive 3 days, the administration would be discontinued if uterine contraction occurred for over 3 times/hour in the course. The control group was treated with pitocin by adding 1 U into 500 mL 5% glucose for intravenous dripping in 6 h, once every day for 3 successive days. The blank group was treated by placebo of CZD, administrated in same way as that in the treated group. The length and width of cervix and diameter of neck tube in all the women were measured on the very day of medication and 72 h later or parturient time by vaginal B-ultrasonography, and the cervical maturation degree was scored referring to the clinical Bishop scale. In the experimental study, the cervical tension of pregnant rats was measured with an in vitro cervical tension-meter, rats' cervical tissues were taken for pathologic examination to observe its morphological change. The total effective rate for promoting cervical maturation was 96.67% in the treated group and 83.33% in the control group. It was significantly superior in the treated group to that in the control group and the blank group (Pcongestion with massive amount of inflammatory cells infiltration, increased matrix components, and many leucocyte and fibroblast in the stroma could be seen. CZD can change the morphorlogic structure of cervical tissue, decrease cervical tension, so as to promote the cervical maturation and induce labor.

Serous tubal intraepithelial carcinoma (STIC), the putative precursor of the majority of extrauterine high-grade serous carcinomas, has been reported in both high-risk women (those with a germline BRCA mutation, a personal history of breast carcinoma, and/or family history of breast or ovarian carcinoma) and average risk women from the general population. We reviewed grossly normal adnexal specimens from 388 consecutive, unselected women undergoing surgery, including those with germline BRCA mutation (37 patients), personal history of breast cancer or family history of breast/ovarian cancer (74 patients), endometrial cancer (175 patients), and a variety of other conditions (102 patients). Among 111 high-risk cases and 277 non-high-risk cases, 3 STICs were identified (0.8%), all in non-high-risk women (high risk vs. non-high risk: P=not significant). STIC was found in 2 women with nonserous endometrial carcinoma and 1 with complex atypical endometrial hyperplasia. Salpingoliths (mucosal calcifications), found in 9% of high-risk cases, and fimbrial adenofibromas in 9.9% of high-risk cases, were significantly more common in high-risk as compared with non-high-risk women (1.8% and 2.5%, respectively; PSTIC and endometrial hyperplasia and carcinoma, and clarify the frequency of non-neoplastic tubal findings in grossly normal fallopian tubes.

To investigate the sequential changes in signal intensity (SI) of normal and abnormal uteri, T1-weighted images were taken repeatedly after the injection of Gd-diethylenetriaminepentaacetic acid (DTPA). Six volunteers and 19 patients with known uterine body malignancy (18 carcinomas, one carcinosarcoma) were examined. The results in volunteers were as follows. In the secretory phase, SI of the endometrium was stronger in the late images than in the early ones, whereas in the proliferative phase, SI was stronger in the early images. SI of the myometrium decreased rapidly and there were no differences in SI between menstrual phases. In 17 of 18 endometrial carcinomas, the tumors showed hypointensity relative to the myometrium, and the contrast between the tumor and the myometrium was better in the early images. In the remaining two cases, the tumor showed hyperintensity and the contrast was better in the late images. After the injection of Gd-DTPA, the endometrium appeared differently according to the menstrual cycle in normal volunteers, and the appearance of uterine structures and endometrial malignant tumors changed sequentially. These findings must be kept in mind when evaluating uterine diseases by Gd-DTPA enhanced MRI. (author)

Intrauterine growth restriction (IUGR) remains a major problem in swine production since the associated low birth weight leads to high rates of pre-weaning morbidity and mortality plus permanent retardation of growth and development. Complex biological events-including genetics, epigenetics, maternal maturity, maternal nutrition, placenta efficiency, uterine capacity, and other environmental factors-can affect fetal growth and development during late gestation, as well as maturity of oocytes, duration of estrus, and both implantation and placentation of conceptuses in uteri of sows. Understanding the physiological changes related to initiation and progress of IUGR are, therefore, of great importance to formulate nutritional strategies that can mitigate IUGR in gilts and sows. Altering the nutritional status of sows prior to mating and during early-, mid-, and late-gestation may be effective at increasing the uniformity of oocytes and conceptuses, decreasing variation among conceptuses during elongation and implantation, and preventing increases in within-litter variation in fetal weights during late gestation. This review summarizes current progress on physiological alterations responsible for IUGR fetuses, as well as possible nutritional interventions to prevent the initiation and continuation of IUGR in gilts and sows. © 2017 Wiley Periodicals, Inc.

Full Text Available INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16 by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC, six cases were Keratinized Squamous Cell Carcinoma (KSCC and four cases were Adenocarcinoma (ADC. Immunohistochemistry study showed positivity in eleven cases (55%; seven cases (35% were non-keratinized squamous cell carcinoma; three cases (15% were keratinized squamous cell carcinoma and one case (5% belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC. The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinomas

Premenopausal women undergoing adjuvant chemotherapy and/or radiotherapy for Breast Cancer (BC) treatment have significant bone loss. This high bone mineral density loss can lead to an increased risk of fractures. In this study, there were evaluated parameters involved in osteoporosis when rats were subjected to a chemotherapy regimen (TC) and/or irradiation (IR). Female Wistar rats were divided into 3 groups: control (G1), TC+IR (G2) and IR (G3). The animals were euthanized after 5 months at the end of treatment and their femurs were excised and dissected. Sections of 10 μm thick were used for μXRF analysis at the National Laboratory of Synchrotron Light. The uteri of these rats were collected and weighed. The obtained results showed that animals from G2 had a significant reduction (pbone composition of the femurs. This same result was notobserved in animals from G1 and G3 groups. These results suggest that early menopause occurs and osteoporosis begins, probably because of the absence, or reduced, production of estrogen. The presence of iron in the G2 samples in indicates the process of osteoporosis, because according to literature, this ion is competitive with calcium ions.

Gestational trophoblastic neoplasm (GTN), choriocarcinoma in coexistence with primary cervical adenocarcinoma, is a rare event not easy to diagnose. Choriocarcinoma is a malignant form of GTN but curable if metastases do not appear early and spread fast. We presented choriocarcinoma in coexistence with primary cervical adenocarcinoma in a 48-year-old patient who had radical hysterectomy because of confirmed cervical carcinoma (Dg: Carcinomaporo vaginalis uteri FIGO st I B1). Histological findings confirmed cervical choriocarcinoma with extensive vascular invasion and apoptosis but GTN choriocarcinoma was finally confirmed after immunohystochemical examinations. Preoperative serum human gonadotropine (beta hCG) level stayed unknown. This patient did not have any pregnancy-like symptoms before the operation. The first beta hCG monitoring was done two months after the operation and found negative. According to the final diagnosis the decision of Consilium for Malignant Diseases was that this patient needed serum hCG monitoring as well as treatment with chemotherapy for high-risk GTN and consequent irradiation for adenocarcinoma. The early and proper diagnosis of nonmetastatic choriocarcinoma of nongestational origine in coexistence with cervical carcinoma is curable and can have good prognosis.

Induction of canine deciduoma in some reproductive stages with the different condition of corpora lutea.

Bitches were examined to see whether canine deciduoma could be induced at some reproductive stages with the different conditions of corpora lutea by inserting a silk suture into the uterine lumen. The bitches stimulated in the early and middle stages of diestrus or in unilateral pregnancy corresponding to these diestrous stages formed deciduoma at a high induction rate, however, no difference in the strength of decidual reaction between the pregnant and diestrous stages was recognized. On the other hand, no reaction could be seen in bitches in late diestrus, the late stage of unilateral pregnancy or the post partum repair phase in which stromal decidual cells similar to those of the rodentia can be seen. In already implanted uteri, however, no deciduoma was formed in the interplacental areas. Even though the corpora lutea were functional, new additional stimulations were not accepted at the interplacental area in which the uterine horn had already been influenced by fertilized ova. From these results, it was suggested that in the dog as well as the rodentia, the endometrium has to be under the influence of functional corpora lutea in order to form deciduoma.

The potential of magnetic resonance imaging (MRI) was evaluated in 21 female subjects: seven volunteers, 12 patients scanned for reasons unrelated to the lower genitourinary tract, and two patients referred with gynecologic disease. The uterus at several stages was examined; the premenarcheal uterus (one patient), the uterus of reproductive age (12 patients), the postmenopausal uterus (two patients), and in an 8 week pregnancy (one patient). The myometrium and cyclic endometrium in the reproductive age separated by a low-intensity line (probably stratum basale), which allows recognition of changes in thickness of the cyclic endometrium during the menstrual cycle. The corpus uteri can be distinguished from the cervix by the transitional zone of the isthmus. The anatomic relation of the uterus to bladder and rectum is easily outlined. The vagina can be distinguished from the cervix, and the anatomic display of the closely apposed bladder, vagina, and rectum is clear on axial and coronal images. The ovary is identified; the signal intensity from the ovary depends on the acquisition parameter used. Uterine leiomyoma, endometriosis, and dermoid cyst were depicted, but further experience is needed to ascertain the specificity of the findings

This is the most severe form of placenta accreta and may result in spontaneous uterine rupture, a rare complication that threatens the life of both mother and fetus. In this case report, we describe a 32-year-old woman in her fourth pregnancy, diagnosed with repeated placenta accreta, which was eventually complicated by spontaneous uterine rupture at 24 weeks’ gestation. This patient had a history of abnormal placentation in prior pregnancies and previous uterine injuries. This case demonstrates a pattern of escalating placental invasiveness, and raises questions regarding the process of abnormal placentation and the manifestation of uterine rupture in scarred uteri.

A simplified assay for the detection of progesterone receptors (PR) in human breast tissue is described. Tissue storage is at -20 deg. C rather than -70 deg. C and a centrifugation speed of 20,000 rpm avoids requirement of an ultracentrifuge. Cytosol preparations obtained from homogenized oestradiol benzoate primed wistar rat uteri performed satisfactorily as positive controls with stability of two months in liquid nitrogen. The use of iodinated tracer (progesterone 11 alpha glucuronide 125 I iodotyramine) proved disappointing in the progesterone receptor assay in contrast to 125 I oestradiol which worked well in a oestrogen receptor assay, previously developed. Hydroxyl-apatite was a better separating agent than dextran coated charcoal in both assays and yielded better sensitivity, particularly when protein concentrations were low. Five breast cancer specimens assayed yielded, by Scatchard analysis, Kd values between 12 to 22x10 -9 m|h, comparable to the positive controls. However, two of these had binding site capacity of less than 5 fmol/mg cytosol as compared to the three others and the positive controls where values ranged from 47-196 fmol/mg cytosol. 28 refs, 6 figs, 14 tabs

Polycystic ovary syndrome (PCOS), a complex endocrine disorder, is a leading cause of female infertility. An obvious reason for infertility in PCOS women is anovulation. However, success rate with high quality embryos selected by assisted reproduction techniques in PCOS patients still remain low with a high rate of early clinical pregnancy loss, suggesting a problem in uterine receptivity. Using a dehydroepiandrosterone-induced mouse model of PCOS, some potential causes of decreased fertility in PCOS patients were explored. In our study, ovulation problem also causes sterility in PCOS mice. After blastocysts from normal mice are transferred into uterine lumen of pseudopregnant PCOS mice, the rate of embryo implantation was reduced. In PCOS mouse uteri, the implantation-related genes are also dysregulated. Additionally, artificial decidualization is severely impaired in PCOS mice. The serum estrogen level is significantly higher in PCOS mice than vehicle control. The high level of estrogen and potentially impaired LIF-STAT3 pathway may lead to embryo implantation failure in PCOS mice. Although there are many studies about effects of PCOS on endometrium, both embryo transfer and artificial decidualization are applied to exclude the effects from ovulation and embryos in our study.

Ambros, R A; Kurman, R J

1993-10-01

Ulex europaeus agglutinin I (UEA-I), a lectin which specifically binds L-fucose, has been shown to extensively bind endometrial carcinoma cells but not benign endometrial glands. Patterns of UEA-I binding were examined in five cases of uteri containing proliferative endometrium, five cases of endometrial hyperplasia, and 54 cases of endometrioid (typical) carcinoma of the endometrium and correlated with the histologic features of the tumor and its behavior. Whereas proliferative endometrium showed luminal staining only, diffuse cytoplasmic staining was frequently seen in hyperplasia and carcinoma. Carcinomas with a high percentage of tumor cells staining with UEA-I tended to be high-grade with a greater tendency to deep myometrial and vascular invasion than tumors with little or no staining. By univariate survival analysis, the extent of UEA-I binding was found to correlate with patient survival. By multivariate analysis, however, survival correlated most closely with the presence of deep myometrial and vascular invasion, and UEA-I binding was not found to be an independent prognostic indicator. This study suggests that increased fucosylation of proteins in endometrioid cancer cells may play a role in myometrial and vascular invasion.

1993-01-01

The existence of high-affinity and low-capacity specific binding sites for luteinizing hormone/human chorionic gonadotropin (hCG) has been reported in porcine, rabbit and rat uteri. The authors have identified the hCG binding sites in the human endometrium collected from 35-42-year-old ovulatory and anovulatory women. The binding characteristics of hCG to endometrial tissue preparations from ovulatory and anovulatory women showed saturability with high affinity and low capacity. Scatchard plot analysis showed the dissociation constant of specific binding sites in the ovulatory women to be 3.5x10 -10 mol/l and in anovulatory women to be 3.1x10 -10 mol/l. The maximum binding capacity varied considerably between ovulatory and anovulatory endometrium. Among the divalent metal ions tested Zn 2+ effected a remarkable increase in [ 125 I]hCG binding to the endometrium, whereas Mn 2+ showed a marginal increase and other metal ions did not have any effect. Data obtained with human endometrium indicate an influence of the functional state of the ovary on [ 125 I]hCG binding to endometrium. 14 refs., 3 figs

Human papilloma virus in oral cancer.

Cervical cancer is the second most prevalent cancer among women, and it arises from cells that originate in the cervix uteri. Among several causes of cervical malignancies, infection with some types of human papilloma virus (HPV) is well known to be the greatest cervical cancer risk factor. Over 150 subtypes of HPV have been identified; more than 40 types of HPVs are typically transmitted through sexual contact and infect the anogenital region and oral cavity. The recently introduced vaccine for HPV infection is effective against certain subtypes of HPV that are associated with cervical cancer, genital warts, and some less common cancers, including oropharyngeal cancer. Two HPV vaccines, quadrivalent and bivalent types that use virus-like particles (VLPs), are currently used in the medical commercial market. While the value of HPV vaccination for oral cancer prevention is still controversial, some evidence supports the possibility that HPV vaccination may be effective in reducing the incidence of oral cancer. This paper reviews HPV-related pathogenesis in cancer, covering HPV structure and classification, trends in worldwide applications of HPV vaccines, effectiveness and complications of HPV vaccination, and the relationship of HPV with oral cancer prevalence.

The nucleoli in squamous cell carcinoma of cervix uteri with special reference to early changes of irradiation by metrical comparison

1976-01-01

The mean number of nucleoli in a cancer cell is 1.51, which is apparently larger in number than that in a normal cell (1.17), although there are slight differences in number by the histological types of cancer. Although there are slight differences in the location and shape of nucleoli between the histological types of cancer, they resembles those of normal cells in shape and location (the nucleoli are located in the center, and circular or circuloid in shape). The size of nucleoli is 1.58 times larger than that of normal cells both by histogram and by mean values. According to the histological classification, the nucleoli of keratinized large cells were more enlarged than those of undifferentiated small cells. As for the change in the number of nucleoli due to irradiation, the tendency to increase in number began to be noted with 500 rads irradiation, and becomes more remarkable with the increase of dose. Especially, it is observed more often in small cell carcinoma than large cell carcinoma. No remarkable change was observed in their location and shape with 1,000 or less rads. However, with about 2,000 rads nucleoli tended to be irregular in shape. There was a tendency of increasing in size with 2,000 rads, on histogram and mean values. Therefore, the change of nucleoli consists of the increase in number and swelling. This fact is important in radiation pathology as well as in the diagnosis of radiosensitivity. (N. Kanao)

Clinical endometritis is an important disease of dairy cattle and results in decreased reproductive performance. This disease is caused by contamination of the uterus with a broad spectrum of microorganisms after calving. In this study, staphylococcal isolates from the uterus of dairy cows with clinical endometritis were tested for their distribution of superantigen (SAg) genes and antimicrobial resistance. Between the 127 staphylococcal isolates collected in this study, 10 species were identified. The predominant strain identified was Staphylococcus aureus (n=53), followed by Staphylococcus saprophyticus (n=38) and Staphylococcus chromogenes (n=22). PCR analysis demonstrated that most isolates (63.0 per cent) harboured at least one SAg gene. The most commonly observed SAg gene and genotype was selj (38.6 per cent) and sec-selj-seln (24.0 per cent), respectively. Most isolates were resistant to penicillin (79.5 per cent), ampicillin (71.7 per cent), erythromycin (56.7 per cent), and tetracycline (52.0 per cent). PCR analysis demonstrated that the antimicrobial resistance determinants ermA, ermB, ermC, tetK, tetM and blaZ were detected in 0 per cent, 44.4 per cent, 51.4 per cent, 68.2 per cent, 13.6 per cent and 86.1 per cent of the erythromycin, tetracycline and β-lactam resistant isolates, respectively. There were 22 (17.3 per cent of all isolates) coagulase-negative staphylococci shown to be methicillin resistant. In the methicillin-resistant isolates, significant resistances to ampicillin, erythromycin and penicillin were observed (P<0.01). The results of this study demonstrate that staphylococci recovered from dairy cows with clinical endometritis contain an extensive and complex prevalence of SAg genes. Significant resistances to antibiotics were also seen, highlighting the need for the rational appliance of antibiotics in veterinary medicine. British Veterinary Association.

1983-01-01

When Selectron afterloading machines were introduced in the Christie Hospital the first aim was to reproduce, as closely as possible, the isodose distributions achieved with the traditional Manchester Radium System. This resulted in the establishment of standard pellet loading patterns, and standard treatment times, for programming the Selectron channels. However, the availability of whole-body CT scanning facilities provides a method of accurately locating the source positions with respect to the local anatomy and hence the possibility of dosage control based on doses to specific pelvic structures. Various computer programs have been written to extract source position data from the CT images, to allow the operator to propose pellet loading patterns and treatment times, and ultimately to display the resultant isodose distribution superposed on the cross-sectional scans. The effects on the dose distribution arising from changing the number of pellets, the pellet positions within the applicators, and the treatment times, are briefly discussed. (author)

Mycosis fungoides (MF) is an uncommon cutaneous neoplasm in dogs. Treatment options are limited. Total skin electron therapy (TSET) has been suggested as a possible therapy for canine MF. To describe the use of TSET as palliative treatment for MF in a dog. An adult dog, previously diagnosed with nonepidermolytic ichthyosis, was presented with generalized erythroderma, alopecia and erosions. Histopathology revealed a densely cellular, well-demarcated, unencapsulated infiltrate extending from the epidermis to the mid-dermis compatible with MF. The infiltrate exhibited epitheliotropism multifocally for the epidermis, infundibula and adnexa. Due to a lack of response to chemotherapy, TSET was elected. Six megavoltage electrons were delivered using a 21EX Varian linear accelerator. A dose of 6 Gy was delivered to the skin surface and a 100 cm skin to surface distance was used for dog setup. The treatment time for the cranial half treatment was 3 h. The treatment was divided in two sessions (cranial and caudal halves of the body) 15 days apart. Clinical and histopathological complete remission was achieved and the dog was kept in remission with no additional treatments for 19 months before relapse and development of Sézary syndrome. To the best of the authors' knowledge, this is the first case reporting the use of TSET for medically refractory canine MF with post treatment follow-up. This case suggests that the use of TSET may be an effective palliative treatment for canine MF. © 2017 ESVD and ACVD.

Ocular surface infections that include infections of conjunctiva, adnexa, and cornea have the potential risk of causing blindness within a given population. Empirical antibiotic therapy is usually initiated based on epidemiological data of common causative agents. Thus, the aims of this study were to determine the bacterial agents and their susceptibility patterns of isolates from ocular surface specimens in our hospital. This is a retrospective analysis and records of bacterial isolates from ocular surface specimens in Hospital Universiti Sains Malaysia from January 2001 to December 2010 were examined. Specimens were processed according to standard laboratory procedures. Antimicrobial susceptibility testing was conducted based on Clinical and Laboratory Standards Institute recommendations. Only single, nonrepetitive isolates were included in the analysis. A total of 1,267 isolates were obtained during the study period, which comprised Staphylococcus aureus (n = 299, 23.6%), Pseudomonas aeruginosa (n = 194, 15.3%), Streptococcus pneumoniae (n = 108, 8.5%), Haemophilus influenzae (n = 100, 7.9%), Haemophilus parainfluenzae (n = 84, 6.6%), and Enterobacter spp. (n = 81, 6.4%). Fungi contributed to 4.4% of the total isolates. The antimicrobial susceptibility testing demonstrated that gram-positive bacteria were generally resistant to gentamicin (19%-57%), whereas gram-negative bacteria were resistant to chloramphenicol (27%-58%). Based on the above results, knowledge of the initial Gram stain findings is imperative before the commencement of empirical antibiotic therapy. Therefore, a simple Gram staining for all eye specimens is highly recommended.

Common variable immunodeficiency (CVID) is a primary immunodeficiency manifesting as a reduction in the level of total immunoglobulin (Ig) G, a reduction in the level of either IgA or IgM, poor response to polysaccharide vaccine, and usually frequent infections. The association of CVID with an increased risk of malignancy, specifically lymphoma, is well known. A 63-year-old female with a past medical history significant for CVID presented with a 1-month history of dull, left eye pain with proptosis, hypoglobus, and left upper lid fullness without a discrete palpable mass. Magnetic resonance imaging (MRI) of the orbits revealed a diffuse infiltrating orbital mass superonasally with extension into the superior rectus muscle, medial rectus muscle, and optic nerve up to the orbital apex and ethmoid sinus. A superonasal orbital biopsy with a caruncular approach was performed and demonstrated a sparse lymphoid infiltrate that was suggestive for a large B-cell neoplasm. Positron emission tomography (PET) scan demonstrated a hypermetabolic right lymph node, anterior to the right submandibular gland, which was biopsied and histopathology confirmed diffuse large B-cell lymphoma (DLBCL). Our patient achieved a very good response to chemotherapy with minimal residual disease on PET scan at the end of treatment. She attained a complete remission after radiation therapy. In conclusion, patients with new orbital and adnexa masses in the setting of a primary immunodeficiency can have an aggressive malignancy such as DLBCL and early diagnosis and systemic treatment carries a good prognosis.

Ectopic pregnancy after two times tubal ligation: a case report

Full Text Available Background: Tubal sterilization is the permanent and effective contraception method. This can be performed at any time, but at least half are performed in conjunction with cesarean or vaginal delivery and are termed puerperal. The most complication after tubal ligation is ectopic pregnancy. Ectopic pregnancy is the leading cause of maternal death in first trimester.Case presentation: We present a 33 years old woman gravida5, para4, all normal vaginal delivery, presented with complaints of delayed menstrual period, pelvic pain and spotting. She underwent tubal ligation for two times. For the first time she had puerperal Pomeroy tubal sterilization after third child delivery. Intra uterine pregnancy occurred three years later. One day after vaginal delivery of fourth child, she underwent post partum tubal ligation with the Parkland method. Tubal pregnancy occurred nine months later. Physical examination identified acute abdomen. Pelvic ultrasound showed no gestational sac in uterine cavity. The sac with fetal pole was in right adnexa. Beta-HCG was 2840mIU/ml. She underwent laparotomy. Surgical management included salpingectomy with cornual resection in both sides. The surgery identified Ectopic pregnancy.Conclusion: Any symptoms of pregnancy in a woman after tubal ligation must be investigated; an ectopic pregnancy should be excluded. Ectopic pregnancy must be considered, in any woman with lower abdominal pain, missed period and vaginal bleed-ing. Conception after tubal sterilization can be explained by fistula formation and re-canalization of fallopian tube.

To investigate the epidemiology of eye injuries sustained by professional basketball players in the National Basketball Association (NBA). A prospective study involving all NBA athletes who sustained eye injuries between February 1, 1992, and June 20, 1993, was conducted. Twenty-seven NBA team athletic trainers, physicians, and ophthalmologists were provided data forms to complete for any player examined for an eye injury. Practice and game exposures during the preseason, regular season, playoffs, and championships were included. Of the 1092 injuries sustained by NBA players during the 17-month period, 59 (5.4%) involved the eye and adnexa. Eighteen (30.5%) of the injuries occurred while the player was in the act of rebounding, and 16 (27.1%) while the player was on offense. The most common diagnoses included 30 abrasions or lacerations to the eyelid (50.9%), 17 contusions (edema and/or ecchymosis) to the eyelid or periorbital region (28.8%), and seven corneal abrasions (11.9%). There were three orbital fractures (5.1%). Most injuries were caused by fingers (35.6%) or elbows (28.8%). Nine players (15.3%) missed subsequent games because of their injury. Fifty-seven players (96.6%) were not wearing protective eyewear at the time of injury. The incidence of eye injuries in NBA players during the 17-month period was 1.44 per 1000 game exposures. Frequent physical contact in professional basketball players leaves them at great risk for sustaining eye injuries. To prevent these injuries, protective eyewear is recommended.

2011-01-01

Junctions between different types of epithelia are hot spots for carcinogenesis, but the junction of the peritoneal mesothelium with the fallopian tubal epithelium, the tubal-peritoneal junction, has not been characterized earlier. A total of 613 junctional foci in 228 fallopian tube specimens from 182 patients who underwent surgery for a variety of indications, including 27 risk-reducing salpingo-oophorectomy specimens, were studied. Edema, congestion, and dilated lymphatic channels were commonly present. Transitional metaplasia was found at the junction in 20% of patients and mesothelial hyperplasia in 17%. Inflammation at the junction was seen predominantly in patients with salpingitis, torsion, or tubal pregnancy. Ovarian-type stroma was found at the junction in 5% of patients, and was found elsewhere in the tubal lamina propria in an additional 27% of patients. Findings in risk-reducing salpingo-oophorectomy specimens in women with BRCA mutations, a personal history of breast cancer, and/or a family history of breast/ovarian cancer were similar to those in controls. Transitional metaplasia specifically localizes to this junction, and is the probable source of Walthard cell nests. The recently highlighted significance of fimbrial tubal epithelium in the origin of serous ovarian carcinomas and a study suggesting that mucinous and Brenner tumors may arise from transitional-type epithelium in this location suggest that the tubal-peritoneal junction may play a role in the development of these tumors. This is the first comprehensive description of a hitherto unrecognized transitional zone in the adnexa.

Congenital or torsion-induced absence of Fallopian tubes. Two case reports.

1998-05-01

Unilateral absence of a uterine tube is an extremely rare finding, for which there are two possible etiopathogenic causes: in some cases it is due to haemorrhage filling of the cavity and its reabsorption as a result of asymptomatic torsion of the uterine tube during adult life, in pediatric age or even during intrauterine life; alternatively, the absence may be congenital, associated with developmental alterations of the mesonephric and paramesonephric ducts. The article presents two cases of fallopian tube absence: a congenital monolateral absence and a tubal torsion during pregnancy. The symptomatology of the torsion of the fallopian tube in pregnancy can be milder than in the classic description with peritoneal reaction and severe clinical alteration. The main risk factors for tubal torsion are: adhesions and inflammatory processes, ovarian cysts, usually of dermoid type, menstrual period, pregnancy, abnormal long mesosalpinx and/or mesovarium, pelvic congestion induced by constipation and disturbed venous blood flow from the adnexa. A congenital defect of the mesonephric duct is followed by a homolateral defect of the paramesonephric duct. The resulting anomaly is characterized by the absence of the uterine tube, uterus-tube angle, kidney and ureter. Partial or total unilateral defects of a paramesonephric duct are more common than aplasia of both ducts. Some authors have suggested that an inadequate blood supply during the descent into the pelvis of the caudal part of the paramesonephric duct might feasibly lead to incomplete tube development.

The unmasking of estradiol receptor in paraffin sections of Bouin's-fixed uterine tissue from ovariectomized gilts was attained with microwave treatment. Immunocytochemistry of the receptor was performed using a polyclonal or five monoclonal antibodies, two of which are commercially available, reacting with different domains of the protein and an amplified-peroxidase system for detection. With five of the antibodies, a predominance of nuclear staining was observed in cells of endometrial glands, while one monoclonal antibody (13H2), reacting with the receptor's domain E, showed a preference for the cytoplasmic receptor. In stroma, all antibodies detected more receptor in nuclei than in cytoplasm. In epithelium, the commercially available antibody H222, our monoclonals 13H2 and HT65, and the polyclonal antibody 402 demonstrated more receptor in cytoplasmic than in nuclear areas. In myometrium, the nuclei from longitudinal and ring muscles were definitely stained with the antibodies. We conclude that the accessibilities of the antibody epitopes of the receptor differ according to the functional uterine cell type.

1999-01-01

A significant decrease in the percentage of women showing contrasuppression of blood lymphocytes, as compared with control, was identified (p ≤ 0.1); it was particularly low at terminal stage (III - IV). Surgery and subsequent radiotherapy were followed by further inhibition, particularly in terminally-ill patients. Two or three years after treatment the numbers of patients in all stage groups, showing contrasuppression increased reaching the initial, i.e. lower than normal levels. However, contrasuppression induces rose to normal in patients immunized with tularemia live vaccine (p ≥ 0.05). This effect was observed in patients of all stage groups, immunized prior to treatment, on days 15 - 20 after immunization. Normal levels of contrasuppression were maintained during treatment and 2 - 3 years on. Both contrasuppression level and stage of tumor may serve as a criterion of gravity of disease and prognosis [ru

Objective: To study the effects of 13-cis-retinoic acid on the tamoxifen induced uterine histological changes in the rabbit. Study Design: Experimental - randomized controlled trial. Place and Duration of study: The study was conducted for 4 months at the department of Anatomy, Army Medical College and National Institute of Health in 2007. Material and Methods: The animals were randomly divided into three groups, a control group A, and two experimental groups B and C, consisting of thirty rabbits each. The experimental groups were treated with tamoxifen only and tamoxifen plus retinoic acid, respectively. The animals were sacrificed after three months. The uteri were then processed for paraffin embedding. Sections were then assessed for the luminal epithelial height, endometrial area and percentage of mitotic figures. Results: The results obtained were suggestive of uterine proliferation by tamoxifen. The adjuvant administration of 13-cis-retinoic acid produced a statistically significant (p = 0.002) inhibitory effect on the tamoxifen induced increase in the area of endometrium, whereas no significant suppressive effect of this drug has been observed on the other parameters when compared with Group B. Conclusion: 13-cis Retinoic acid has not shown a significant role in the reversal of tamoxifen induced changes in the uterine tissue after a short term administration of three months. (author)

Dimethyl sulfoxide (DMSO) is a widely used solvent and cryoprotectant that can cause impaired blood flow, reduction in intracranial pressure, tissue edema, inflammatory reactions, inhibition of vascular smooth muscle cell migration and proliferation, processes which can lead to atherosclerosis of the coronary, peripheral and cerebral circulation. Although the adverse effects are rare when DMSO is administered in clinically established concentrations, there is no safe antagonist for an overdose. In this work, we treated isolated spontaneous and calcium-induced contractile active rat uteri (Wistar, virgo intacta), with DMSO and fullerenol C{sub 60}(OH){sub 24} nanoparticle (FNP) in DMSO. FNP is a water-soluble derivative of fullerene C{sub 60}. Its size is a 1.1 nm in diameter and is a very promising candidate for a drug carrier in nanomedicine. FNP also displays free radical scavenging activity. DMSO decreased both spontaneous and calcium-induced contractions. In contrast, FNP only decreased spontaneous contraction. FNP decreased copper-zinc superoxide dismutase activity and prevented the DMSO-induced increase in glutathione reductase activity. Atomic force microscopy detected that FNP aggregated with calcium ions. Our results indicate that FNP has properties that make it a good candidate to be a modulator of DMSO activity which could minimize side effects of the latter.

Pooled ejaculates from six fertile boars were frozen under controlled conditions in Teflon FEP-film plastic bags (5 ml) and maxi-straws (2.5 ml) using 3% glycerol as cryoprotectant. The percentages of both post-thaw motility and normal apical ridges were significantly higher (P less than 0.001) for the bags (54.5 and 75%) than for the maxi-straws (40.1 and 59.4%) respectively. For evaluation of the in vivo fertilizing capacity of the frozen-thawed spermatozoa, 26 gilts were inseminated once 24 h after the first observation of standing reflex in their second oestrus, with 5 ml of semen (containing 5 billion spermatozoa) reconstituted in 80 ml of BTS from either bags or maxi-straws. Ova were recovered from the oviducts/uteri 2-4 days following insemination and examined for cleavage and sperm binding to the zona pellucida (ZP). Significantly higher rates (P less than 0.02) of fertilized ova were found in the bag-inseminated (75%) than in maxi-straw inseminated gilts (63%); and similarly their ova had significantly more spermatozoa in the ZP, irrespective of whether they were fertilized or nonfertilized. This study confirmed that the plastic bags are suitable and may be used for packaging single insemination doses of deep frozen boar semen for routine A.I. work.

To evaluate structural alterations in rat endometrium at preimplantation following treatment with aspirin beginning from proestrus by light microscopy, electron microscopy and immunohistochemical techniques. Twenty rats were divided into control (n = 10) and experimental (n = 10) groups. Experimental rats were treated with low-dose aspirin daily (2 mg/kg/day) during estrus, beginning from the proestrus phase, mated at end of cycle and treated with aspirin. Untreated pregnant rats were the control group. Rats in both groups were sacrificed at the 84th pregnancy hour; the uterus was rapidly removed and dissected free of surrounding adipose tissue. Uteri specimens from nonpregnant rats were transferred into fixative solution and processed for light, electron microscopic and immunohistochemical study. Light and electron microscopy of endometrium from control rats conformed to mid-diestrus phase; endometrial histology of the aspirin-treated group conformed to late diestrus phase. The endometrial layer was significantly thicker in the aspirin-treated group compared to the untreated control group (p <0.001). No significant difference was found in vessel number between groups. Staining with alphaV integrin was more dense in the aspirin-treated group. Based on histologic findings, we suggest low-dose aspirin has positive effects on preparing endometrium before implantation.

Ionizing radiations severely interfere with normal embryonic or fetal development, although period of late fetal development in mammals is considered to be the somewhat radioresistant. Here, an attempt is made to check the radiation induced developmental anomalies by vitamins during fetal development period. For this purpose, pregnant Swiss albino mice were exposed to 0.50 Gy gamma radiation during fetal growth period (day 14.25 post-coitus) in the presence (experimental) or absence (control) of vitamin B complex (20 mg/kg b.w.) till term. All dams were sacrificed on day 18 post-coitus and their uteri were examined to study reproductive status and anatomical abnormalities of each conceptus. About 48% pregnant females of the control group showed a complete embryonic resorption while in the experimental group the number of females showing resorption was only 33%. Resorption of embryos, fetal mortality and reduction in placental weight were significantly increased in mice irradiated in the absence of vitamin B complex. Various gross malformations including skeletal anomalies were significantly reduced in 18 days old fetuses given vitamin B complex therapy. Further, such fetuses had better ossification of skull and vertebrae. Sex-ratio of the fetuses, however, remained unaltered in both groups as compared to normal. (orig.)

Full Text Available Abstract Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII and the Slope Index of Inequalities (SII. All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003. Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

The authors conducted a case-control study designed to evaluate the association between radiotherapy for a first primary cancer and subsequent leukemia risk. Study subjects were selected from four tumor registries (California, Connecticut, Kansas, and Massachusetts). Cases were subjects with two primary concers; the second cancer was a leukemia diagnosed one year or more after the diagnosis of the first primary cancer. Control subjects were patients with single cancers. Two control subjects were chosen for each case matched for tumor registry, site of the first primary cancer, date of diagnosis of the first primary cancer, age, sex, and duration of survival after the first primary cancer. Separate analyses were carried out for chronic lymphatic leukemia (166 cases) and all other leukemias (232 cases). The relative risk of chronic lymphatic leukemia after radiotherapy was 0.7 and did not differ significantly from unity. For all other leukemias, relative risks were 1.6 after radiotherapy for first primary cancers of all sites, 2.4 after radiotherapy to trunk sites, 2.2 after radiotherapy for breast cancer, and 10.3 after radiotherapy for cancer of the corpus uteri. These relative risks for leukemias other than chronic lymphatic leukemia all differed significantly from unity

A 60-year-old female developed an adenocarcinoma at the site of double-barrel sigmoid colostomy. She underwent a total hysterectomy and the subsequent radiation therapy due to carcinoma uteri when she was 34 years old. She had rectal stenosis one year later and underwent sigmoid colostomy. She had been healthy thereafter, however, when she was 58 years old, she noticed an elevated lesion at the site of colostomy. Biopsy revealed well-differentiated adenocarcinoma, so surgery was recommended but she refused it. Two years later, the entire stoma became a carcinoma, which directly invaded the abdominal wall on MRI images. A bow-shaped skin incision was made and en bloc resection of the tumor, colostomy and the surrounding tissues was performed. Finally, descending colostomy in the left upper quadrant of the abdomen was reconstructed. Primary adenocarcinoma occurring at a double-barrel colostomy is very rare, and such a case may never have been reported, although there were some reports of carcinoma occurring at an end colostomy. Since the site of the present carcinoma was radiated, the radiation may contribute to this carcinogenesis, suspecting its late effect. Our surgical procedure enabled simultaneously operation of combined resection and intraabdominal manipulation, and the reconstruction site of the stoma was easily selected. (author)

Radiotherapy for malignant tumors is effective and established. However, there are many complications in radiotherapy. A typical complication is radiation enterocolitis. It is difficult to treat severe histological damage to the irradiated tissues. This paper reports our experience with 26 patients with radiation enterocolitis for whom surgical treatment was given during a period of 16 years in our surgical department. The most frequent original disease requiring irradiation was cancer of the cervix uteri (15 cases) which was followed by cancer of the urinary bladder (7 cases). All of these patients had received external 60 Co irradiation. The ileum was the most frequent site of the lesion, followed by the rectum, sigmoid and descending colon. The period between the end of irradiation and the onset of enterocolitis ranged from 2 months to 10 years, with an average of 28 months. The main symptoms were intestinal obstruction in the ileum, and melena and fistula in the rectum and sigmoid colon. Intestinal resection was performed in 10 patients, a bypass operation in 4, and colostomy in 12. As to types of intestinal suture in these cases, Gambee's single layer method was thought useful from our experience. Colostomy as surgical management of melena and fistula did not yield satisfactory results. (author)

The purpose of this study is to evaluate the destructive impact of the widely used nutritional flavouring agent, monosodium glutamate (MSG) and/or radiation stress on the female rats mothers and their developing embryos as judged by the maternal biochemical and embryological morphological and histopathological lesions induced. MSG is the sodium salt of glutamic acid, widely used as a food additive and flavour enhancer in modern nutrition. MSG (4 mg/rat) was daily administered subcutaneously to pregnant female rats from the 10 th to the 15 th gestational days during which they were subjected to intermittent radiation dose levels of 0.5 Gy increments delivered every other day up to a cumulative dose of 1.5 Gy whereas investigation has been carried out one day prior to parturition. MSG and radiation dual treatment resulted in increased maternal serum levels of lipid peroxides, total lipids, triglycerides, cholesterol and sodium together with decreased calcium concentrations. consequently, the developing embryos in the uteri, due to their increased sensitivity, showed various teratological and histological impairments . MSG and/or radiation induced effects were detected as growth retardation, malformations, intrauterine death and embryonic resorption. moreover, embryonic histological examination revealed ill-shaped vertebrae with degenerated osteogenic layer together with severely degenerated neurons

The aims of this study were to compare two different methods of quantifying the colour of the luminal surface of the equine endometrium and to relate the results to histopathological evidence of inflammation and fibrosis. The mucosal surfaces of 17 equine uteri obtained from an abattoir were assessed using a spectrophotometer and by computer-assisted analysis of photographs. Values were converted into L(*)a(*)b(*) colour space. Although there was significant correlation between the two methods of quantification, variations in 'brightness', 'red' and 'yellow' values were noted. Within a given uterus, measurements using the spectrophotometer did not differ significantly. Using photographic analysis, brightness differed between horns, although no differences in chromaticity were found. Histopathological classification of changes within endometria corresponded to measured differences in colour. Extensive fibrosis was associated with increased brightness and decreased chromaticity using both methods. Inflammation correlated with reduced chromaticity, when measured by spectrophotometry, and with reduced brightness and yellow values, when assessed photographically. For this technique to gain wider acceptance as a diagnostic tool, e.g. for the endoscopic evaluation of uterine mucosae in vivo, standardised illumination techniques will be required so that colours can be compared and interpreted accurately.

AIM: To evaluate the potential usefulness of transcatheter uterine artery embolization as a treatment for symptomatic adenomyosis in patients without uterine fibroids. MATERIALS AND METHODS: Uterine artery embolization using polyvinyl alcohol particles sized 250-710 mm was performed in 43 patients (mean; 40.3 years, range; 31-52 years) with dysmenorrhoea, menorrhagia, or bulk-related symptoms (pelvic heaviness, urinary frequency) due to adenomyosis without fibroids. All patients underwent pre-procedural and 3.5 months (range 1-8 months) follow-up magnetic resonance imaging (MRI) with contrast enhancement. Clinical symptoms were also assessed at the time of MRI before and after embolization. RESULTS: Significant improvement of dysmenorrhoea (95.2%) and menorrhagia (95.0%) was reported in most patients. Contrast-enhanced MRI revealed non-enhancing areas suggesting coagulation necrosis of adenomyosis in 31 patients (72.1%), decreased size without necrosis in 11 patients (25.6%), and no change in one patient (2.3%). The mean volume reduction of the uteri after uterine artery embolization was 32.5% (from 321.7{+-}142.9 to 216.7{+-}130.1 cm{sup 3}). CONCLUSION: Transcatheter uterine artery embolization is an effective therapy for the treatment of symptomatic pure adenomyosis, and may be a valuable alternative to hysterectomy.

Numerous antinuclear demonstrations reveal that the public is anxious about the potential health effects caused by nuclear power plants. The purpose of this study is to address the question "Is there a higher cancer incidence rate in the vicinity of nuclear power plants in Taiwan?" The Taiwan Cancer Registry database from 1979 to 2003 was used to compare the standardized incidence rate of the top four cancers with strong evidence for radiation risks between the "plant-vicinity" with those "non-plant-vicinity" groups. All cancer sites, five-leading cancers in Taiwan, and gender-specific cancers were also studied. We also adopted different observation time to compare the incidence rate of cancers between two groups to explore the impact of the observation period. The incidences of leukemia, thyroid, lung, and breast cancer were not significantly different between two groups, but cervix uteri cancer showed higher incidence rates in the plant-vicinity group. The incidence of cervical cancer was not consistently associated with the duration of plant operation, according to a multiyear period comparison. Although there was higher incidence in cervix cancer in the plant-vicinity group, our findings did not provide the crucial evidence that nuclear power plants were the causal factor for some cancers with strong evidence for radiation risks.

Principles of cobalt-60 teletherapy including an introduction to the compendium. Guidelines for the documentation of radiation treatment methods

International Nuclear Information System (INIS)

Cohen, M.

1984-01-01

A great deal of thought has been given in recent years to the documentation of individual patients and their diseases, especially since the computerization of registry sytems facilitates the storage and retrieval of large amounts of data, but the documentation of radiation treatment methods has received surprisingly little attention. The guidelines which follow are intended for use both internally (within radiotherapy centres) and externally when a treatment method is reported in the literature or transferred from one centre to another. The amount of detail reported externally will, of course, depend on the circumstances: for example, a published paper will usually mention only the most important of the radiation and physical parameters, but it is important for the department of origin to list all parameters in a separate document, available on request. These guidelines apply specifically to the documentation of treatment by external radiation beams, although many of the suggestions would also apply to treatment by small sealed sources (brachytherapy) and by unsealed radionuclides. Treatment techniques which involve a combination of external and internal sources (e.g. Ca. cervix uteri treatd by intracavitary sources plus external beam therapy) require particularly careful documentation to indicate the relationship bwtween dose distribution (in both space and time) achieved by the two modalities

Rabbit uterine epithelial cells: Co-culture with spermatozoa

Boice, M.L.

1988-01-01

A primary culture of rabbit uterine epithelial cells was established and their effects on sperm function were examined in vitro. Epithelial cells were isolated from uteri of estrous rabbits and cultured on floating collagen gels in phenol red-free medium supplemented with 5% fetal bovine serum. Light microscopy and keratin staining showed that the epithelial cell population established in culture had morphological characteristics similar to that seen in the intact endometrium. Cells were cultured with 3 H-leucine and uptake of label by cells and its incorporation into cellular and secretory proteins determined. When compared to cells cultured for 24-48 h, incorporation of label into cellular protein was lower at 72-96 h, but secretion increased. Estradiol 17-β did not affect label uptake or incorporation, but did enhance proliferation of cells as judged by total DNA content of the cell population. Analysis of proteins in media by sodium dodecyl sulfate polyacrylamide gel electrophoresis and fluorography suggested that epithelial and stromal cells synthesis proteins that may be secretory in nature during 72-96 h culture. Twenty-nine to thirty-one h after initiation of epithelial cultures, 1-2 x 10 6 sperm were co-incubated with cells and sperm viability, motility, loss of acrosome and fertilizing ability determined

Impaired progesterone (P4) signaling is linked to endometrial dysfunction and infertility in women with polycystic ovary syndrome (PCOS). Here, we report for the first time that elevated expression of progesterone receptor (PGR) isoforms A and B parallels increased estrogen receptor (ER) expression in PCOS-like rat uteri. The aberrant PGR-targeted gene expression in PCOS-like rats before and after implantation overlaps with dysregulated expression of Fkbp52 and Ncoa2 , two genes that contribute to the development of uterine P4 resistance. In vivo and in vitro studies of the effects of metformin on the regulation of the uterine P4 signaling pathway under PCOS conditions showed that metformin directly inhibits the expression of PGR and ER along with the regulation of several genes that are targeted dependently or independently of PGR-mediated uterine implantation. Functionally, metformin treatment corrected the abnormal expression of cell-specific PGR and ER and some PGR-target genes in PCOS-like rats with implantation. Additionally, we documented how metformin contributes to the regulation of the PGR-associated MAPK/ERK/p38 signaling pathway in the PCOS-like rat uterus. Our data provide novel insights into how metformin therapy regulates uterine P4 signaling molecules under PCOS conditions. © 2018 Society for Endocrinology.

Short-Term Isoflavone Intervention in the Treatment of Severe Vasomotor Symptoms after Surgical Menopause: A Case Report and Literature Review

Full Text Available Isoflavones are soy phytoestrogens that potentially exert various favorable effects in postmenopausal women, for example, alleviating vasomotor episodes, attenuating bone loss, and stimulating vaginal epithelial maturation. There has, however, been lack of consensus regarding those therapeutic effects. Most clinical studies of isoflavones have been conducted with women who had undergone natural menopause, but not those who had undergone surgical menopause. This study reports on a 51-year-old woman who presented with severe vasomotor episodes after undergoing a hysterectomy and a bilateral oophorectomy due to hypermenorrhea secondary to myoma uteri. She refused hormone therapy due to fear of adverse drug reactions so was treated with oral soy isoflavones (two capsules twice daily, equivalent to at least 100 mg daily dose for 8 weeks. The number and severity of hot flushes and her menopause-specific quality of life dramatically improved from baseline values. The serum bone resorption marker (beta C-telopeptide decreased markedly, while vaginal epithelial maturation improved slightly, suggesting the potential of isoflavones in attenuating bone loss and stimulating vaginal maturation. The intervention did not adversely affect the hormonal profile (FSH, LH, and estradiol and liver or renal functions. Thus, isoflavones could be an option for women experiencing severe vasomotor episodes after surgical menopause.

To assess the estrogenic activities of synthetic estrogen, synthetic phytoestrogen, Pueraria lobata and three distinct cultivars of Pueraria mirifica, a phytoestrogen-rich herb, a vaginal cytology assay in ovariectomized rats were used. Rats were ovariectomized and treated with DW, estradiol valerate (1 mg/kg BW), genistein (0.25-2.5 mg/kg BW), Pueraria lobata and Pueraria mirifica (10-1,000 mg/kg BW) for 14 days. The vaginal cytology was checked daily and the uteri were dissected and weighed at the end of treatment or post-treatment periods. The treatments of DW, genistein and Pueraria lobata did not influence the vaginal epithelium, but the injection of estradiol valerate induced a vaginal cornification from day-3 of treatment to day-14 of post-treatment period. The occurrence of vaginal cornification after treatment and the recovery after the cessation was dependent on dosages and cultivars of Pueraria mirifica. The increments of uterus weight in all rats agreed with the cornification of vaginal epithelium. Although both uterotropic and vaginal cytology assays can be used to assess the estrogenic activity of phytoestrogen-rich herb, however, using vaginal cytology assay has two advantages: (1) we do not need to kill the animals and (2) we can follow up the recovery after the cessation of treatment.

The Effects of Ibogaine on Uterine Smooth Muscle Contractions: Relation to the Activity of Antioxidant Enzymes

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Ibogaine is an indole alkaloid originally extracted from the root bark of the African rainforest shrub Tabernanthe iboga. It has been explored as a treatment for substance abuse because it interrupts drug addiction and relieves withdrawal symptoms. However, it has been shown that ibogaine treatment leads to a sharp and transient fall in cellular ATP level followed by an increase of cellular respiration and ROS production. Since contractile tissues are sensitive to changes in the levels of ATP and ROS, here we investigated an ibogaine-mediated link between altered redox homeostasis and uterine contractile activity. We found that low concentrations of ibogaine stimulated contractile activity in spontaneously active uteri, but incremental increase of doses inhibited it. Inhibitory concentrations of ibogaine led to decreased SOD1 and elevated GSH-Px activity, but doses that completely inhibited contractions increased CAT activity. Western blot analyses showed that changes in enzyme activities were not due to elevated enzyme protein concentrations but posttranslational modifications. Changes in antioxidant enzyme activities point to a vast concentration-dependent increase in H2O2 level. Knowing that extracellular ATP stimulates isolated uterus contractility, while H2O2 has an inhibitory effect, this concentration-dependent stimulation/inhibition could be linked to ibogaine-related alterations in ATP level and redox homeostasis.

Estrogenic activity was analysed by uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein and cholesterol level in uteri horn. Administration of extracts to the doses of 100 and 200 mg.kg-1 exhibits increase of uterine dry and wet weight, surrenal gland wet weight, vaginal opening, protein levels and decrease of level of cholesterol in uterine horn. The results suggest that, aqueous extracts of Holarrhena fl oribunda possesses estrogenic type effect. But when 100 and 200 mg.kg-1 of Holarrhena fl oribunda were given alone with 25 mg.kg-1 of estradiol 17-β, the estrogenic effect was slight. These results supposed that H. fl oribunda is a weak phytoestrogen and the aqueous extracts of the leaves behad as partial agonistic

The objective of the study was to investigate the angioarchitectonics and the functional morphology of the vessels of the cervix and to clarify the role of structural features of these vessels in preventing hemorrhaging in parturition during cervical dilatation. Cervixes uteri were obtained from corpses of 30 women of various ages and 5 ablated at labor. Series of histotopographical specimens of the cervixes were processed using histological and histochemical methods. Peculiar features of the angioarchitectonics, histotopography and structure of cervical vessels were encountered. Arteries penetrating the cervix are surrounded by tight muffs of anastomizing veins that are closely adjacent to the arteries. In other cases, the arteries are located within the lumen of veins--"vessels within vessels". Cervical arteries make up subendocervical convolutions. During pregnancy, smooth muscle "cushions" develop in the vessels. The cervix is pierced by a network of veins that divide the cervical tissue into separate stromal "lobules". This peculiar vascular architecture might be important structural basis of the vascular hemostatic mechanism in the neck of the uterus triggered by labor. It prevents vessel rupture, hemorrhaging and amniotic fluid and air embolism during cervical dilatation. The venous network that passes through the cervix makes it easy for the separate stromal "lobules" of the cervix to move relative to each other during cervical dilatation.

AIM: To evaluate the potential usefulness of transcatheter uterine artery embolization as a treatment for symptomatic adenomyosis in patients without uterine fibroids. MATERIALS AND METHODS: Uterine artery embolization using polyvinyl alcohol particles sized 250-710 mm was performed in 43 patients (mean; 40.3 years, range; 31-52 years) with dysmenorrhoea, menorrhagia, or bulk-related symptoms (pelvic heaviness, urinary frequency) due to adenomyosis without fibroids. All patients underwent pre-procedural and 3.5 months (range 1-8 months) follow-up magnetic resonance imaging (MRI) with contrast enhancement. Clinical symptoms were also assessed at the time of MRI before and after embolization. RESULTS: Significant improvement of dysmenorrhoea (95.2%) and menorrhagia (95.0%) was reported in most patients. Contrast-enhanced MRI revealed non-enhancing areas suggesting coagulation necrosis of adenomyosis in 31 patients (72.1%), decreased size without necrosis in 11 patients (25.6%), and no change in one patient (2.3%). The mean volume reduction of the uteri after uterine artery embolization was 32.5% (from 321.7±142.9 to 216.7±130.1 cm 3 ). CONCLUSION: Transcatheter uterine artery embolization is an effective therapy for the treatment of symptomatic pure adenomyosis, and may be a valuable alternative to hysterectomy

Full Text Available Purpose: The current classification of ocular trauma does not incorporate adnexal trauma, injuries that are attributable to a nonmechanical cause and destructive globe injuries. This study proposes a new classification system of ocular trauma which is broader-based to allow for the classification of a wider range of ocular injuries not covered by the current classification. Methods: A clinic-based cross-sectional study to validate the proposed classification. We analyzed 535 cases of ocular injury from January 1, 2012 to February 28, 2012 over a 4-year period in an eye hospital in central India using our proposed classification system and compared it with conventional classification. Results: The new classification system allowed for classification of all 535 cases of ocular injury. The conventional classification was only able to classify 364 of the 535 trauma cases. Injuries involving the adnexa, nonmechanical injuries and destructive globe injuries could not be classified by the conventional classification, thus missing about 33% of cases. Conclusions: Our classification system shows an improvement over existing ocular trauma classification as it allows for the classification of all type of ocular injuries and will allow for better and specific prognostication. This system has the potential to aid communication between physicians and result in better patient care. It can also provide a more authentic, wide spectrum of ocular injuries in correlation with etiology. By including adnexal injuries and nonmechanical injuries, we have been able to classify all 535 cases of trauma. Otherwise, about 30% of cases would have been excluded from the study.

High-grade serous carcinomas of ovarian, tubal, and peritoneal origin are together referred as pelvic serous carcinoma. The fallopian tubes, ovarian surface epithelium, and the tuboperitoneal junctional epithelium are all implicated in pelvic serous carcinogenesis. The aim of this study is to identify putative precursor lesions of serous carcinoma including secretory cell outgrowths (SCOUTs), serous tubal intraepithelial carcinoma (STIC), and p53 signatures and assign its probable site of origin. Prospective case-control study of consecutive specimen comprising 32 serous carcinomas and 31 controls (10 normal adnexa, 10 benign and 6 atypically proliferative surface epithelial tumors, and 5 other carcinomas). Sectioning and extensive examination of the fimbrial end (SEE-FIM) protocol along with immunohistochemistry for Bcl-2, p53, and Ki-67 was employed for evaluating invasive carcinoma and precursor lesions in cases versus controls. SCOUT, p53 signatures, and STIC were most frequent in the serous carcinomas. p53 signatures and STIC were always seen in the fimbrial end. STICs were exclusively present in serous carcinomas, more common in ipsilateral tubes of cases with dominant ovarian mass. Multifocal p53 signatures with STIC were seen in 7 (21.9%) cases. STIC was present with or without an invasive carcinoma in 25% and in 6.25% of cases of pelvic serous carcinomas, respectively. The junctional epithelia did not show any lesion in any group. SEE-FIM protocol is recommended for evaluation of sporadicpelvic (ovarian/tubal/peritoneal) serous carcinoma. Based on the presence of STIC or invasive carcinoma, nearly 60% of all pelvic serous carcinomas are of fallopian tubal origin.

Pelvic carcinosarcomas (PCSs) are rare aggressive biphasic tumors that localize in the ovary, fallopian tube, or peritoneum and present frequently as bilateral disease. We undertook a morphological, p53 immunohistochemical and TP53 gene mutational analysis study in a single institution cohort of 16 PCSs in order to investigate the nature of bilateral tumors and to shed light on their origin and pathogenesis. Of the 16 patients, 10 presented with bilateral disease, 6 with a carcinosarcoma in both adnexa, and the remaining cases with a carcinosarcoma in one adnexum and a carcinoma in the opposite. The carcinoma component showed high-grade serous features in 13/16 of cases (81 %). In 10 patients (63 %), a serous tubal intraepithelial carcinoma (STIC) was found, in one case bilateral, making a total of 11 STICs. STIC was found only in cases with a carcinoma component with high-grade serous features. All 10 bilateral tumors and all 11 PCS-associated STICs showed a similar p53 immunostaining pattern. At mutation analysis of the TP53 gene, all five bilateral PCS contained an identical mutation in both localizations. Furthermore, a TP53 mutation was found in 8 of 10 STICs, with an identical mutation in the associated PCS. The finding of similar p53 immunostaining in all bilateral cases and identical TP53 mutations in most PCS-associated STIC provides evidence for a clonal relation between these neoplastic lesions, supporting a metastatic nature of bilateral PCS and suggesting that they have an extraovarian origin in a STIC.

This study aimed to determine the role of electronic health record software in resident education by evaluating documentation of 30 elements extracted from the American Academy of Ophthalmology Dry Eye Syndrome Preferred Practice Pattern. The Kresge Eye Institute transitioned to using electronic health record software in June 2013. We evaluated the charts of 331 patients examined in the resident ophthalmology clinic between September 1, 2011, and March 31, 2014, for an initial evaluation for dry eye syndrome. We compared documentation rates for the 30 evidence-based elements between electronic health record chart note templates among the ophthalmology residents. Overall, significant changes in documentation occurred when transitioning to a new version of the electronic health record software with average compliance ranging from 67.4% to 73.6% (p Electronic Health Record A had high compliance (>90%) in 13 elements while Electronic Health Record B had high compliance (>90%) in 11 elements. The presence of dialog boxes was responsible for significant changes in documentation of adnexa, puncta, proptosis, skin examination, contact lens wear, and smoking exposure. Significant differences in documentation were correlated with electronic health record template design rather than individual resident or residents' year in training. Our results show that electronic health record template design influences documentation across all resident years. Decreased documentation likely results from "mouse click fatigue" as residents had to access multiple dialog boxes to complete documentation. These findings highlight the importance of EHR template design to improve resident documentation and integration of evidence-based medicine into their clinical notes.

This study analysed incidence, patient outcome, immunophenotype and prognostic factors of histological transformation (HT) from extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) to diffuse large B-cell lymphoma (DLBCL) in 467 patients (median age, 61 years). The primary sites of MALT lymphoma were the stomach (43%), ocular adnexa (25%), lung (8%), systemic (8%) and other tissues (16%). HT occurred in 8% of MALT lymphomas. Risk of HT by 15 years was 5%: 4% in limited-stage diseases (n = 385) and 16% in advanced-stage diseases (n = 56) (P = 0·02). The median time to HT was 48 months (range, 4-139). Five-year progression-free survival (PFS) and overall survival (OS) rates after HT were 80% and 94%, respectively. Immunohistochemical results of DLBCL were as follows: germinal centre B-cell (GCB)/non-GCB, 37%/63%; CD10, 9%; BCL6, 59%; MUM1, 38%; MYC, 42%; BCL2, 35%; Ki67 ≥ 90%, 23%; and CD5, 3%. The majority (75%, 9/12) of GCB-type DLBCLs exhibited CD10(-) , BCL6(+) and MUM1(-) immunophenotypes; the remainder had CD10(+) immunophenotypes. Multivariate analysis revealed that only advanced stage at HT was a significant adverse factor for PFS (P = 0·037). Thus, overall risk of HT was low and prognosis after HT was favourable; however, in advanced-stage cases, risk of HT was relatively high and prognosis was unfavourable. © 2016 John Wiley & Sons Ltd.

In most deaths caused by explosions, the fragment of explosive remained on the victim's body can provide valuable clues to forensic investigation. However, the examination of the skin and appendages at the scene of explosion, which may reveal clue to the identity of an individual, has not been extensively studied. Compared with visual appearance of the epidermis surface that affected by various wounds, skin adnexa embedded in the dermis has a more stable morphology as an inner biometric. Hair follicles are formed when a fetus is 5 months old and distributed fairly evenly throughout the body, with the exception of hairless palms and soles. Therefore, we focus on the distribution of hair follicles in order to infer information of age, gender, and race/ethnicity. Optical coherence tomography (OCT) is a novel forensic imaging method, which achieves non-destructive, high-resolution and most importantly cross-sectional imaging. In this study, we design and develop a custom-built spectral-domain three-dimensional (3D) OCT system with a portable handheld probe to detect and reconstruct the hair follicles in the facial skin. We test our system on the forehead and preauricular skin of 2 adult volunteers and demonstrate the high quality visualization of hair follicles beneath the epidermis. The diameter, orientation, density and shape of hair follicles can be extracted from the 3D volume data. The preliminary analysis suggests that these parameters vary from different part of body and have individual difference. Eventually, we believe 3D OCT is promising tool for the examination of hair follicles for forensic purpose.

To assess intraoperative blood splatter to the ocular surface and adnexa during oculofacial surgery. Four surgeons and multiple assistants at three separate locations wore a total of 331 protective eye shields during 131 surgeries. Postoperatively, a luminol blood detection system was used to identify blood splatter on the shields. In the event of positive blood splatter, the total number of blood spots was counted. Controls were used to verify the blood detection protocol. A postoperative questionnaire was given to all surgeons and assistants after each case, and they were asked whether intraoperative blood splatter was noticed. Blood was detected on 61% of eye shields and in a total of 80% of surgical cases. However, only 2% of blood splatters were recognized intraoperatively by the surgical participants. There was no significant difference in the splatter rate between surgeons (64%), assistants (60%), and surgical technicians (58%) (p = 0.69). Shields worn during full-thickness eyelid procedures, direct brow lifting, orbitotomy with bony window, and orbital fracture repairs were more likely to be splattered (p = 0.03), and there was a significant difference between splatter rates among different surgeons (range, 29-90%; p = 0.0004), suggesting that blood splatter rate may be both procedure dependent and surgeon dependent. Mucocutaneous and transconjunctival transmission of human immunodeficiency virus and viral hepatitis has been documented. These results suggest that oculofacial plastic surgeons should consider eye protection for patients with known blood-borne diseases and in cases where blood splatter is expected. This precautionary practice is supported by the high incidence (98%) of undetected, intraoperative blood splatter.

Intermittent torsion of a normal ovary in a child associated with use of a trampoline.

Ovarian torsion is rare in children. It usually occurs in the presence of ovarian or pelvic pathology. The course of symptoms is typically hours to days. Some authors have speculated that sudden acceleration/deceleration movements may precipitate torsion. The objective of this report is to describe a case of intermittent abdominal pain lasting nearly 6 months, which started when the child began playing regularly on a trampoline, and was ultimately diagnosed as intermittent ovarian torsion of an otherwise normal ovary. A 12-year-old girl presented to the Emergency Department (ED) with 2 h of abdominal pain and vomiting. She reported similar episodes over the previous 6 months. Initial ultrasound, obtained between episodes, was normal. Repeat ultrasound at ED presentation showed no blood flow to the left adnexa. Surgery confirmed the ovary to be twisted 1080 degrees and markedly edematous due to vascular engorgement. The family retrospectively identified the onset of the first episode as happening the same week the child had begun playing regularly on a trampoline. After surgery, she no longer played on the trampoline. At follow-up 22 months later, she had had no recurrence of her symptoms. Intermittent ovarian torsion should be considered as a rare cause of recurrent abdominal pain in children. The presence of blood flow with Doppler ultrasound during acute symptoms does not exclude the diagnosis. Clinicians might also ask about unusual physical activities because several authors have theorized that ovarian torsion could be precipitated by sudden acceleration/deceleration movements.

A 56-year-old G3P3 postmenopausal woman presented with a 5 month history of abnormal uterine bleeding and pelvic pain. A computed tomographic scan revealed a 5 cm right adnexal cystic mass in addition to a thickened, heterogenous endometrium and leiomyomatous uterus. A total laparascopic hysterectomy and bilateral salpingo-oophorectomy with omental and peritoneal biopsy were performed. Gross examination revealed a 12 week size uterus with small fibroids, normal bilateral atrophic ovaries, and a right paratubal cyst. A 4 cm vegetating mass was found in the right side of the uterine wall. Microscopically, the uterine mass was diagnosed as an endometrioid adenocarcinoma (EAC) FIGO 1 with 70% of myometrial invasion. The remaining endometrium showed a complex atypical hyperplasia. In addition, a 5 cm paratubal cystic mass was found that was separate from the uterus and the right adnexa. The cyst content was a chocolate brown fluid and the cyst wall was smooth with a single solid mass of 2 cm in size. The diagnosis of EAC, FIGO 1 was given. The remaining cyst lining showed endometriotic cyst and foci of endometriosis in the cyst wall. There was no lymphovascular invasion. The entire fallopian tube and ovaries were submitted and they were free of tumor. The patient was diagnosed with primary EAC of the paratubal cyst in addition to EAC of the uterine corpus (pT1b). A close follow-up was recommended. Because of our limited knowledge of carcinomas arising in the paratubal cyst, we will review the literature and discuss their clinical aspects, management, and behavior.

Purpose: To validate a Monte Carlo model and evaluate the dosimetric capabilities of a novel commercial CT/MR compatible Fletcher applicator for cervical cancer brachytherapy. Methods: MCNPX 2.7.0 was used to model the Fletcher CT/MR shielded applicator (FA) and 192Ir HDR source. Energy deposition was calculated with a track length estimator modified by an energy-dependent heating function. A high density polystyrene phantom was constructed with three film pockets for validation of the MCNPX model. Three planes of data were calculated with the MCNPX model corresponding to the three film planes in phantom. The planes were located 1 cm from the most anterior, posterior, and medial extents of the FA right ovoid. Unshielded distributions were calculated by modeling the shielded cells as air instead of the tungsten alloy. A third order polynomial fit to the OD to dose curve was used to convert OD of the three film planes to dose. Each film and MCNPX plane dose distribution was normalized to a point 2 cm from the center of the film plane and in a region of low dose gradient. MCNPX and film were overlaid and compared with a distance-to-agreement criterion of (±2%/±2mm). Shielded and unshielded distributions were overlaid and a percent shielded plot was created. Results: 85.2%, 97.1%, and 96.6% of the MCNPX points passed the (±2%/±2mm) criterion respectively for the anterior, lateral, and posterior film comparison planes. A majority of the points in the anterior plane that exceeded the DTA criterion were either along edges of where the film was cut or near the terminal edges of the film. The percent shielded matrices indicated that the maximum % shielding was 50%. Conclusion: These data confirm the validity of the FA Monte Carlo model. The FA ovoid can shield up to 50% of the dose in the anteroposterior direction

The history on the relationship of VPH infection and cervical cancer was examined. Findings were initially reported in Maracaibo(1971), later in Mexico(1973) and thereafter several studies on the ultrastructure and immunohistochemistry of VPH infection and its role on cervical cancer were described. The ultrastructural findings of viral particles of HPV and their proteins, as well as their role in the incorporation of the viral genome to the human cervical cells were also described. Glycoproteins on the surface of cervical cells were reviewed and their importance on HPV infection was related to p16, blood group antigens and early genetic changes in the cell cycle with loss of heterozigocity, all of which, stimulated by the high risk HPV infection lead to cervical cancer.

These findings suggest that regulatory cascades involving DLX5/6 might be at the origin of endometriosis symptoms such as chronic pelvic pain (CPP. We have shown that inactivation of Dlx5 and Dlx5/6 in the mouse uterus results in an endometrial phenotype reminiscent of endometriosis. Methods: We focused on genes that present a similar deregulation in endometriosis and in Dlx5/6-null mice in search of new endometriosis targets. Results: We confirmed a strong reduction of DLX5 expression in endometriosis implants. We identified a signature of 30 genes similarly deregulated in human endometriosis implants and in Dlx5/6-null mouse uteri, reinforcing the notion that the downregulation of Dlx5/6 is an early event in

The differential diagnosis is difficult and occasionally definite diagnosis cannot be established even after clinical and histopathological findings are taken together. We describe a case of a middle-aged man who presented with a 10-year history of voluminous eyelid swelling with concomitant late-onset atopic manifestations, namely bronchial asthma and allergic rhinitis with nasal polyps. After thorough clinical and laboratory investigation, including a biopsy of the eyelid, we classified the patient’s disease to a rare entity that has been relatively recently described: periocular xanthogranuloma associated with adult-onset asthma. In a review of the literature, no prospective trials concerning the treatment of this disease were found. The literature mainly contained case reports and case series in which corticosteroids and chemotherapy with alkylating agents have been reported to be beneficial. We treated our patient with a combination of oral corticosteroids and cyclophosphamide pulses and we observed substantial regression of the eyelid masses together with a normalization of systemic immunologic abnormalities.Keywords: periocular xanthogranuloma, adult-onset asthma, non-Langerhans histiocytoses, cyclophosphamide, methylprednisolone

Anhidrotic ectodermal dysplasia (AED) is an inherited syndrome, which originates mainly from genetic alteration of the ectodysplasin A (EDA) gene. It regularly affects the adnexa of the skin which results in a characteristic phenotype of the patients including hypo- or anhidrosis leading to severe disturbances in the regulation of body temperature. To prevent the development of the symptoms in early childhood promising therapeutic approaches are currently under clinical investigation. In this context, timely diagnosis of this genetic syndrome is crucial. The purpose of our study was the investigation of modern non-invasive imaging methods such as optical coherence tomography (OCT) and reflectance confocal microscopy (RCM) in the immediate diagnosis of AED. We examined a 3-year-old boy with the suspicion for an AED syndrome and his family members with RCM and OCT to document presence and characteristic features of sweat glands in comparison to non-affected individuals. The patient and the affected brother showed significantly reduced sweat glands in the imaging compared to the controls. The genetic analysis revealed a mutation of the EDA gene for hemizygosity previously associated with AED and the mother was revealed as the conductor of the genetic alteration. With the help of non-invasive imaging, we were able to detect sweat gland dysplasia in the affected family members without performing a biopsy which led us to the diagnosis of an AED. The application of modern dermatological imaging techniques might serve as valuable supplementary tools in the immediate, non-invasive diagnosis of genetic syndromes especially in newborns when early therapeutic approaches are planned. © 2015 European Academy of Dermatology and Venereology.

White-nose syndrome (WNS) has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesions that are the hallmark of the disease. The fungal infection is characterized by a white powdery growth on muzzle, ears and wing membranes. While WNS may threaten some species of North American bats with regional extinction, infection in hibernating bats in Europe seems not to be associated with significant mortality. We performed histopathological investigations on biopsy samples of 11 hibernating European bats, originating from 4 different countries, colonized by G. destructans. One additional bat was euthanized to allow thorough examination of multiple strips of its wing membranes. Molecular analyses of touch imprints, swabs and skin samples confirmed that fungal structures were G. destructans. Additionally, archived field notes on hibernacula monitoring data in the Harz Mountains, Germany, over an 11-year period (2000-2011) revealed multiple capture-recapture events of 8 banded bats repeatedly displaying characteristic fungal colonization. Skin lesions of G. destructans-affected hibernating European bats are intriguingly similar to the epidermal lesions described in North American bats. Nevertheless, deep invasion of fungal hyphae into the dermal connective tissue with resulting ulceration like in North American bats was not observed in the biopsy samples of European bats; all lesions found were restricted to the layers of the epidermis and its adnexae. Two bats had mild epidermal cupping erosions as described for North American bats. The possible mechanisms for any difference in outcomes of G. destructans infection in European and North American bats still need to be elucidated.

White-nose syndrome (WNS) is a cutaneous fungal disease of hibernating bats associated with a novel Geomyces sp. fungus. Currently, confirmation of WNS requires histopathologic examination. Invasion of living tissue distinguishes this fungal infection from those caused by conventional transmissible dermatophytes. Although fungal hyphae penetrate the connective tissue of glabrous skin and muzzle, there is typically no cellular inflammatory response in hibernating bats. Preferred tissue samples to diagnose this fungal infection are rostral muzzle with nose and wing membrane fixed in 10% neutral buffered formalin. To optimize detection, the muzzle is trimmed longitudinally, the wing membrane is rolled, and multiple cross-sections are embedded to increase the surface area examined. Periodic acid-Schiff stain is essential to discriminate the nonpigmented fungal hyphae and conidia. Fungal hyphae form cup-like epidermal erosions and ulcers in the wing membrane and pinna with involvement of underlying connective tissue. In addition, fungal hyphae are present in hair follicles and in sebaceous and apocrine glands of the muzzle with invasion of tissue surrounding adnexa. Fungal hyphae in tissues are branching and septate, but the diameter and shape of the hyphae may vary from parallel walls measuring 2 microm in diameter to irregular walls measuring 3-5 microm in diameter. When present on short aerial hyphae, curved conidia are approximately 2.5 microm wide and 7.5 microm in curved length. Conidia have a more deeply basophilic center, and one or both ends are usually blunt. Although WNS is a disease of hibernating bats, severe wing damage due to fungal hyphae may be seen in bats that have recently emerged from hibernation. These recently emerged bats also have a robust suppurative inflammatory response.

To compare the association between the Case Mix Group (CMG) code and length of stay (LOS) with the association between the type of procedure and LOS in patients admitted for gynaecology surgery. We examined the records of women admitted for surgery in CMG 579 (major uterine/adnexal procedure, no malignancy) or 577 (major surgery ovary/adnexa with malignancy) between April 1997 and March 1999. Factors thought to influence LOS included age, weight, American Society of Anesthesiologists (ASA) score, physician, day of the week on which surgery was performed, and procedure type. Procedures were divided into six categories, four for CMG 579 and two for CMG 577. Data were abstracted from the hospital information costing system (T2 system) and by retrospective chart review. Multivariable analysis was performed using linear regression with backwards elimination. There were 606 patients in CMG 579 and 101 patients in CMG 577, and the corresponding median LOS was four days (range 1-19) for CMG 579 and nine days (range 3-30) for CMG 577. Combined analysis of both CMGs 577 and 579 revealed the following factors as highly significant determinants of LOS: procedure, age, physician, and ASA score. Although confounded by procedure type, the CMG did not significantly account for differences in LOS in the model if procedure was considered. Pairwise comparisons of procedure categories were all found to be statistically significant, even when controlled for other important variables. The type of procedure better accounts for differences in LOS by describing six statistically distinct procedure groups rather than the traditional two CMGs. It is reasonable therefore to consider changing the current CMG codes for gynaecology to a classification based on the type of procedure.

Full Text Available Context: High-grade serous carcinomas of ovarian, tubal, and peritoneal origin are together referred as pelvic serous carcinoma. The fallopian tubes, ovarian surface epithelium, and the tuboperitoneal junctional epithelium are all implicated in pelvic serous carcinogenesis. Aims: The aim of this study is to identify putative precursor lesions of serous carcinoma including secretory cell outgrowths (SCOUTs, serous tubal intraepithelial carcinoma (STIC, and p53 signatures and assign its probable site of origin. Settings and Design: Prospective case-control study of consecutive specimen comprising 32 serous carcinomas and 31 controls (10 normal adnexa, 10 benign and 6 atypically proliferative surface epithelial tumors, and 5 other carcinomas. Subjects and Methods: Sectioning and extensive examination of the fimbrial end (SEE-FIM protocol along with immunohistochemistry for Bcl-2, p53, and Ki-67 was employed for evaluating invasive carcinoma and precursor lesions in cases versus controls. Results: SCOUT, p53 signatures, and STIC were most frequent in the serous carcinomas. p53 signatures and STIC were always seen in the fimbrial end. STICs were exclusively present in serous carcinomas, more common in ipsilateral tubes of cases with dominant ovarian mass. Multifocal p53 signatures with STIC were seen in 7 (21.9% cases. STIC was present with or without an invasive carcinoma in 25% and in 6.25% of cases of pelvic serous carcinomas, respectively. The junctional epithelia did not show any lesion in any group. Conclusions: SEE-FIM protocol is recommended for evaluation of sporadicpelvic (ovarian/tubal/peritoneal serous carcinoma. Based on the presence of STIC or invasive carcinoma, nearly 60% of all pelvic serous carcinomas are of fallopian tubal origin.

[The advantages of early midtrimester targeted fetal systematic organ screening for the detection of fetal anomalies--will a global change start in Israel?].

Despite more than three decades of universal popularity of fetal sonography as an integral part of pregnancy evaluation, there is still no unequivocal agreement regarding the optimal dating of fetal sonographic screening and the type of ultrasound (transvaginal vs abdominal). TransvaginaL systematic sonography at 14-17 weeks for fetal organ screening. The evaluation of over 72.000 early (14-17 weeks) and late (18-24 weeks) fetal ultrasonographic systematic organ screenings revealed that 96% of the malformations are detectable in the early screening with an incidence of 1:50 gestations. Only 4% of the fetal anomalies are diagnosed later in pregnancy. Over 99% of the fetal cardiac anomalies are detectable in the early screening and most of them appear in low risk gestations. Therefore, we suggest a new platform of fetal sonographic evaluation and follow-up: The extensive systematic fetal organ screening should be performed by an expert sonographer who has been trained in the detection of fetal malformations, at 14-17 weeks gestation. This examination should also include fetal cardiac echography Three additional ultrasound examinations are suggested during pregnancy: the first, performed by the patient's obstetrician at 6-7 weeks for the exclusion of ectopic pregnancy, confirmation of fetal viability, dating, assessment of chorionicity in multiple gestations, and visualization of maternal adnexae. The other two, at 22-26 and 32-34 weeks, require less training and should be performed by an obstetrician who has been qualified in the sonographic detection of fetal anomalies. The advantages of early midtrimester targeted fetal systematic organ screening for the detection of fetal anomalies may dictate a global change.

Full Text Available The present study evaluates potential hazardous of nickel (Ni+2 as NiCl2·6H2O to Swiss albino mice fetus. Ni was administered orally on body weight base from days 6 to 13 of gestation period. Based on LD50, Ni doses (46.125, 92.25, and 184.5 mg Ni/kg b.wt. were used. On day 18 of gestation, uteri of the sacrificed dams were examined. A dose-dependent decrease ( in the body weight of the pregnant females and fetuses during the gestation period was observed. Number of implant sites and placental weight at all the three dose levels was lower compared with their respective control groups. Average number of live fetuses/dams reduced significantly ( at 184.5 mg Ni/kg b.wt. with concomitant increase in the percentage of postimplantation death and percentage of resorbed, macerated, and dead fetuses, respectively. Exposure increased the fetal malformations, namely, hydrocephaly, open eyelids, microphthalmia, exophthalmia, club foot, umbilical hernia, and skeletal anomalies. Reduced ossification of nasal, frontal, parietal, intraparietal, and supraoccipital bones, absence/gap between the ribs, reduced/fused sternebrae, vertebral centra, and caudal vertebrae, reduced pelvic elements, absence of carpals, metacarpals, tarsals, metatarsals, and phalanges were distinct. This indicates vulnerability of the mice fetus to nickel during prenatal exposure.

Full Text Available Iron oxide nanoparticles (NPs are commonly utilized for biomedical, industrial, and commercial applications due to their unique properties and potential biocompatibility. However, little is known about how exposure to iron oxide NPs may affect susceptible populations such as pregnant women and developing fetuses. To examine the influence of NP surface-charge and dose on the developmental toxicity of iron oxide NPs, Crl:CD1(ICR (CD-1 mice were exposed to a single, low (10 mg/kg or high (100 mg/kg dose of positively-charged polyethyleneimine-Fe2O3-NPs (PEI-NPs, or negatively-charged poly(acrylic acid-Fe2O3-NPs (PAA-NPs during critical windows of organogenesis (gestation day (GD 8, 9, or 10. A low dose of NPs, regardless of charge, did not induce toxicity. However, a high exposure led to charge-dependent fetal loss as well as morphological alterations of the uteri (both charges and testes (positive only of surviving offspring. Positively-charged PEI-NPs given later in organogenesis resulted in a combination of short-term fetal loss (42% and long-term alterations in reproduction, including increased fetal loss for second generation matings (mice exposed in utero. Alternatively, negatively-charged PAA-NPs induced fetal loss (22% earlier in organogenesis to a lesser degree than PEI-NPs with only mild alterations in offspring uterine histology observed in the long-term.

The author observed morphological change in palate development of rat embryo after irradiation of x-ray on the one side of the duplex uterus. The time matings occurred between 6 p.m. and 8 a.m. and all female with copulation plugs at 8 a.m. were isolated and properly marked for evidence of copulation. The lower left abdomen of mothers were exposed to x-radiation on the 7 1/2th, 9 1/2th, 11 1/2th day of gestation, respectively 150, 250, 350, 500 rads. At 18 1/2th day of post-conception, the pregnant female were dissected and the contents of the two uteri examined. The translucent sample by Alizarin red S stain were prepared. The results were as follows; 1. The result that groups irradiated by 250 rads and 350 rads made marked difference in comparison with the control group suggests the x-ray to be an inducing factor of cleft palate. 2. At 11 1/2th day of gestation, incidence of cleft palate induced by x-irradiation was highest. 3. Mortality showed the highest frequency at 7 1/2th day of gestation, and tended to decrease according to increasing of age. 4. Morphology of cleft palate induced by x-irradiation showed similarity in comparison with those induced by other factors having been reported ever.

Kyoberine, a preparation made from berberine, was administered in 20 cases of malignant tumors (16 cases of cervical carcinoma, 2 cases of corpus uteri carcinoma, and 2 cases of ovarian carcinoma) in which diarrhea was an acute symptom resulting from Linac irradiation. Diarrhea occurred frequently in the patients who received 1600 - 2000 rad. In regard to the characteristics of the feces, this drug was remarkably effective in 25% of the patients and effective in 65% total effectiveness, 90%. In regard to the frequency of diarrhea, it was remarkably effective in 30% of the patients and effective in 60% total effectiveness, 90%. A comprehensive assessment of the effect on the characteristics of the feces and the frequency of diarrhea revealed the drug to be remarkably effective in 7 cases (35%) and effective in 11 (55%). After serial administration of the drug, recurrence of diarrhea was noted only in one case out of 18 in which the drug was effective. Examinations of body weight, peripheral blood, the liver, the kidneys, and electrolytes revealed no side effects. This drug had an excellent effect on diarrhea due to Linac irradiation. Because of its depressant action on peristaltic reflexes and its anti-inflammatory and anti-ulcerative actions, it is hoped that it can be used to prevent radiation injuries. (Ueda, J.)

Effects of antiestrogen on progestin binding in uterine cell types were determined and compared to those of estrogen. Effects on uterine morphology were also studied. Immature rats were treated with four daily sc injections of 100 micrograms hydroxytamoxifen [TAM(OH)], 5 micrograms estradiol (E2), or oil. On day 5 the rats were injected iv with 1 microgram of the synthetic progestin [ 3 H]Org 2058, and 1 h later uteri were excised, weighed, and processed for thaw-mount autoradiography. Treatment with TAM(OH) or E2 resulted in uterine weight gain, which was greater in animals treated with E2. E2 treatment resulted in cellular hypertrophy in all tissue compartments, especially in the luminal epithelium and myometrium, but TAM(OH) treatment resulted in hypertrophy of only the luminal epithelium. Treatment with TAM(OH) or E2 changed the pattern and intensity of nuclear binding of [ 3 H]Org 2058 from that in oil-treated controls. E2 increased progestin binding in stroma and myometrium and decreased it in luminal epithelium. TAM(OH), similarly, decreased progestin binding in the luminal epithelium and increased it, albeit less than E2, in the myometrium, but left it unchanged in the stroma. The results indicate that E2 and TAM(OH) differentially effect progestin binding among the uterine tissue compartments

In several Venezuelan public hospitals where cervix uteri tumours are treated by intracavitary radiotherapy, that use manual after loading Fletcher method, with Caesium 137 sources, the use of improper source holders, locally manufactured from pieces of drainage plastic tubing, which deteriorated and created a corrosive environment all around the sources, omission of manufacturer's recommendations regarding corrosion information, source storage, inspection and testing, violation of International Atomic Energy Agency Radiation Protection Procedures, and lack of proper regulatory control, resulted integrity damage to about sixty special form sources (ISO2919 C 63322), leakage of Cs-137 from a supposed insoluble refractory active content (caesium silicoaluminate), and contamination of applicators, floors and bedding. When the situation was detected by means removal contamination tests, after routine inspections, the sources were removed from the hospitals, decontaminated by means of immersion in 3% EDTA solution in ultrasonic bath, subjected to leaking assessment tests, and the ones that passed were placed in low cost stainless steel source holders, designed and built by the instituto Venezolano de Investigaciones Cientificas (IVIC) returned to the hospitals. The leaking sources were removed from use and considered radioactive waste. In order to avoid the occurrence of similar situations, all the importers of such sources are now required to send them to IVIC for testing and placement in proper source holders, before they are shipped to the hospitals.

To study the complications related to leiomyomatosis in pregnancy by clinical and ultrasonographic assessment. A retrospective study. All pregnancies admitted to the 2nd Institute of Gynecology and Obstetrics, Policlinico Umberto I, in the period between January 1992 to December 1993 were surveyed. Gestational age at the time of ultrasonographic neoplasm diagnosis was 25.1 +/- 13.4 weeks, 'we found no correlation between maternal age or parity affecting pregnancy outcome, Leiomyomatosis complicated pregnancy rate was 1.68%. Myomatosis was diagnosed clinically in 25 of 67 cases (37.3%). Regarding the location of the neoplasm, 59% was located in the corpus-uteri, 21% was considered a diffuse neoplasm and the 14% was located in the fundus. Threatened abortion was the most frequent complication (20%), abortion was the second (16.4%). We observed an increased abortion threat rate (p pregnancies complicated by myomatosis, and the indication for surgery was given either primarily or exclusively by the presence of myomatous formation in 19 cases (50%). Our study suggests that location of the leiomyoma in relation to the placenta is a higher risk factor than its size, and that there is a higher risk for threats of abortion and abortion rates in pregnancies complicated by leiomyomatosis. We recommend that every pregnant woman with a suspected myoma should be ultrasonographically scanned.

There has been some evidence that cervical cancer patients who were treated by radiotherapy, had an increased incidence of second primary cancers noticeable 15 years or more after the radiotherapy. The data suggested that high dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but not leukemia (Kleinerman et al., 1982, Morton 1973). The aim of the present work is to estimate the absorbed dose, due to radiotherapy treatment for cervival cancer, to various organs and tissues in the body. Monte Carlo calculations were performed to calculate the organ absorbed doses resulting from intracavitary sources such as ovoids and applicators filled or loaded with radium, Co-60 and Cs-137. For that purpose a routine which simulates an internal source was constructed and added to the existing Monte Carlo code (GSF-Bericht S-885, Kramer et al.). Calculations were also made for external beam therapy. Various anterior, posterior and lateral fields were applied, resulting from megavoltage, Co-60 and Cs-137 therapy machines. The calculated organ doses are tabulated in three different ways: as organ dose per air Kerma in the reference field, according to the recommendations of the International Commission on Radiation Units and Measurements (ICRU Report No 38, 1985); as organ dose per surface dose and as organ dose per tissue dose at Point B.

Full Text Available In the main experiment the total daily protein intake and quality (essential amino-acids was varied in 4 groups of mares. The incidence of oestrus in mares during the transitional period was unaffected by protein nutrition. Ovarian activity, as evaluated by follicular development and size of the ovaries, was affected. Mares that received low-quality protein (Groups 1 and 2 had a higher number of smaller follicles (<10 mm that developed during the transitional period compared to mares on a high-quality protein intake (Groups 3 and 4. The mares that received the high quality protein ovulated 2-3 weeks earlier in the breeding season in a synchronised period of 4-5 weeks compared to a period of 6-8 weeks in Groups 1 and 2. The duration of the subsequent oestrous cycles was not affected. There was no difference in the diameter of the largest follicle of mares between groups on the day before ovulation. In a separate experiment, 5 maiden Anglo-Arab mares, 4-5 years of age, were slaughtered at different stages during the anovulatory, transitional and ovulatory periods of the breeding cycle. The morphology of the ovaries and uteri of these mares was described and photographed for use as guidelines when comparing ovarian changes and follicular activity of mares.

Full Text Available Abstract Background Heat shock proteins (Hsps are a set of highly conserved proteins, Hsp105, has been suggested to play a role in reproduction. Methods Spatio-temporal expression of Hsp105 in rat uterus during peri-implantation period was examined by immunohistochemistry and Western blot, pseudopregnant uterus was used as control. Injection of antisense oligodeoxynucleotides to Hsp105 into pregnant rat uteri was carried out to look at effect of Hsp105 on embryo implantation. Results Expression of Hsp105 was mainly in the luminal epithelium on day 1 of pregnancy, and reached a peak level on day 5, whereas in stroma cells, adjacent to the implanting embryo, the strongest expression of Hsp105 was observed on day 6. The immunostaining profile in the uterus was consistent with that obtained by Western blot in the early pregnancy. In contrast, no obvious peak level of Hsp105 was observed in the uterus of pseudopregnant rat on day 5 or day 6. Furthermore, injection of antisense oligodeoxynucleotides to Hsp105 into the rat uterine horn on day 3 of pregnancy obviously suppressed the protein expression as expected and reduced number of the implanted embryos as compared with the control. Conclusion Temporal and spatial changes in Hsp105 expression in pregnant rat uterus may play a physiological role in regulating embryo implantation.

This was a descriptive cross-sectional study of 1836 Pap smears performed in patients over 15 years during several screening campaigns in Senegal conducted between June 2010 and June 2012. We analyzed epidemiological data, pathological smears, and the proposed management. In 69% of cases, the women were less than 45 years old. They were mostly multiparous and did not use contraceptive methods before. The smears were interpreted in 91.4% (n=1661) and were pathological in 5.2% of cases. They revealed mainly atypical squamous cells of undetermined significance, squamous intraepithelial low-grade lesions, and squamous intraepithelial high-grade lesions, respectively in 2.5% (n=46), 1.7% (n=30) and 1% (n=19) of cases. Multiparity, early marriages were the main risk factors. Patients with pathological smars had colposcopy with cryotherapy (23 cases), and colposcopy and biopsy (13 cases). A hysterectomy was performed in 4 cases. The pathological smear rate found in this study confirms the interest to continue cervical cancer screening with this practice. Strengthening of its geographical and financial access through a national prevention program will effectively help to lower cases of cervical cancer. Copyright © 2016 Elsevier Masson SAS.

Carcinogenesis was found in 150 of 25,692 patients who had received radiotherapy for benign diseases. Of primary diseases subjected to radiotherapy, skin diseases were the most. Carcinogenesis was found in 26 of 7,230 patients with skin diseases (0.36%) and 18 in 2286 patients with tuberculous cervical lymphadenitis (0.79%). The sites of carcinogenesis was the skin in 51 patients, the hypopharynx in 43, and the larynx in 18. Carcinogenesis was also found in 140 of 220,361 patients who had received radiotherapy for malignant tumors. As primary cancer, cancer of the cervix uteri was found in 59 of 48,662 patients, and breast cancer was found in 20 of 27,967 patients. As radiation-induced cancer, leukemia was found in 18 patients, soft tissue sarcoma in 18, skin cancer in 10, osteosarcoma in 6, cancer of the hypopharynx in 6, and cancer of the cervical esophagus in 6. It is necessary to differentiate cancer due to exposure to radiation from delayed recurrent cancer and double cancer. Irradiation fields should be restricted as small as possible in order to reduce carcinogenesis. As leukemia and carcinoma were found in a-bomb survivors exposed to very small dose of a-bomb radiation, carcinogenic mechanisms by chromosome aberrations, carcinogenic rates from a viewpoint of epidemiology, and other factors which influenced carcinogenesis are being investigated.

A well-balanced immunological interaction between mother and the semi-allogenic embryo is of particular importance. The objective of the present study was to analyse mechanisms of immune tolerance in bovine pregnancy during peri-implantation. Simmental heifers inseminated with either cryopreserved spermatozoa or seminal plasma were killed 12, 15 or 18 days after oestrus. Uteri were flushed for the recovery of conceptuses and the ipsilateral intercaruncular endometrium was sampled for gene expression analysis. Indoleamine 2,3-dioxygenase (IDO) mRNA, coding for the initial enzyme of the kynurenine pathway, was 18-fold (P < 0.001) more abundant in the endometrium of Day 18 pregnant v. non-pregnant animals. Tandem mass spectrometry revealed a decrease of endometrial l-tryptophan (P = 0.0008), but an increase of l-kynurenine concentration (P = 0.005) from Day 12 to Day 18, suggesting increasing IDO activity (P < 0.03). An in vitro coculture model of endometrial cells showed an induction of IDO expression following interferon-τ exposure primarily in stroma cells, which was confirmed by in situ hybridisation localising IDO mRNA mainly in deep stroma cells. Immunohistochemical analysis revealed fewer CD45-positive leucocytes in the zona basalis of pregnant animals. Elevated IDO activity may reduce the presence of leucocytes in the pregnant endometrium, providing a possible mechanism for protecting the semi-allogenic conceptus from maternal rejection.

Aim: To evaluate the efficacy and safety of uterine artery embolization for the management of secondary postpartum haemorrhage associated with placenta accreta. Materials and methods: Between January 2005 and August 2011, 45 women with placenta accreta, which was discovered during delivery, were managed conservatively in Peking Union Medical College Hospital. They did not experience severe bleeding during delivery. Ten patients (mean age 31 ± 6.4 years) developed secondary postpartum haemorrhage and underwent uterine artery embolization. The complications, control of haemorrhage, and outcome of the placenta left inside the uterus were retrospectively reviewed. Results: All patients underwent transcatheter embolization of bilateral uterine arteries. The median time between delivery and uterine artery embolization was 11 days (range 3–76 days). The technical success rate of embolization was 100%. Bleeding was controlled in all patients during follow-up (11 ± 6.9 months; range 3–24 months), and no further bleeding occurred. One patient developed lower-extremity deep venous thrombosis after uterine artery embolization, and no other major complications occurred. The placentae that were left inside the uteri gradually decreased in size during follow-up, except in one case. Nine patients resumed normal menstruation. One patient subsequently became pregnant and had an uneventful intrauterine pregnancy carried to term. Conclusion: Uterine artery embolization is safe and effective for the management of secondary postpartum haemorrhage associated with placenta accreta.

Developing a better understanding of the reproductive physiology and breeding condition peculiar to wild Japanese black bears (Ursus thibetanus japonicus) is crucial for estimation of their habitat distribution. The aim of this study was to clarify the changes in morphology of the genital organs, cellular proliferation in the endometrium and sex steroid hormone concentrations along with the reproductive cycle in Japanese black bears. Samples were collected from a total of 24 female Japanese black bears (1-15 presumptive years old) that were caught in the wild in Iwate prefecture during the period between August 1999 and September 2005. Twenty-two out of the 24 animals were hunted from May to October. The ovaries from the 24 animals and the uteri from 23 animals were observed macroscopically and histologically to examine the relationship between morphology of the genital organs and the month of the year the animal was caught. The staining pattern of proliferating cell nuclear antigen (PCNA) in the endometrium was characterised. Peripheral concentrations of oestradiol-17beta and progesterone were determined by radioimmunoassay. All the animals that had a corpus luteum (n=12) were captured from August to October. The thickness of the endometrium in the animals captured from August to October (n=16) was significantly greater than those in animals captured from May to July (n=5) (Pblack bears.

Eggs obtained from the uteri of female nematodes, genetically identified as Contracaecum multipapillatum s.l., found in a brown pelican (Pelecanus occidentalis) from Bahía de La Paz, Gulf of California, Mexico, were used to study the early developmental stages of this anisakid by scanning electron microscopy (SEM). Egg dimensions were approximately 54 × 45 μm measured by SEM. Observation of the eggs revealed an outer surface of fibrous appearance. The newly hatched larvae were ensheathed and highly motile. Observation with SEM showed that the sheaths of the larvae were striated and revealed an excretory pore and a cleft near the anterior end of the sheath, presumably to facilitate the opening of the sheath for the emergence of the larva. The hatched larvae were placed in nutritive culture medium, where they grew within their sheath, some exsheathing completely 2 weeks later. The surface patterns of the sheath and the cuticle of the exsheathed larvae were clearly different. Although they did not moult during culture, SEM revealed a morphology typical of third-stage larvae of Contracaecum from fish, as previously observed by optical microscopy. Thus, we suggest that newly hatched larvae from eggs of C. multipapillatum are third larval stage but with sheath of the second larval stage, as occuring in other anisakids.

Objective: to determine whether endometrial volume or power Doppler indices as measured by 3D ultrasound imaging can discriminate between benign and malignant endometrium in women with postmenopausal bleeding and endometrial thickness > 5 mm. Study design: Eighty-four patients with postmenopausal bleeding and endometrial thickness > 5 mm underwent 3D power Doppler ultrasound examination of the corpus uteri. The endometrial volume was calculated, along with the vascularisation index (VI), flow index and vascularisation flow index (VFI) in the endometrium. The gold standard was the histological diagnosis of the endometrium. Results: There were 56 benign and 28 malignant endometrial. Endometrial thickness and volume were significantly larger in malignant than in benign endometrial, and flow indices in the endometrium were Significantly higher. The area under the ROC curve (AUC) of endometrial thickness was 0.83, that of endometrial volume 0.73, and that of the best power Doppler variable FI 0.93. The best logistic regression model for predicting malignancy contained the variables endometrial thickness and FI. Its AUC was 0.93. Conclusion: the diagnostic performance of endometrial volume measured by 3d imaging with regard to discriminating between benign and malignant endometrium was not superior to that of endometrial thickness measured by 2D ultrasound examination, but 3D power Doppler flow indices are good diagnostic tool in predicting endometrial carcinoma

The analysis of the discovered and treated for eleven years 91 years 912 women with climacteric metrorrhagia from 68 towns with a population of 130 000 showed a percentage which was two to ten times greater concentration in one of the towns. The clinic, paraclinic and histology, as well as social, environmental, nutritional, sexual and other factors which were examined, did not clarify this fact. The authors directed their attention to the natural radioactivity. The concentration of radium 226 and potassium 40 were determined by the standard methods (IAAE-1966) using an apparatus for low concentrations in the samples of blood and urine of the patients as well as in water, soil and plant material from three regions with equal number of population but various ratio of the patients (10:6:4for metrorrhagia climacterica and 10:6:4 for myoma uteri). In the most contaminated region especially in the plant material (e.g. biological indicator) the level of natural radioactivity was almost two times higher at the upper limit of the natural radioactive amount. It could not be excluded that under certain circumstances (absolute estrogemy, young quickly transforming cells of the endometrium, etc.) within these limiits the examined radioactive elements could stimulate proliferative processes and to catalize enzymatic systems, participating in the etiopathogenesis of climacteric metrorrhagia.

In order to evaluate the participation of extrauterine cells in the formation of mouse antimesometrial decidua, [ 3 H]-thymidine was administered ip on days 1, 5 and 6 of pregnancy and the animals were killed 1 h afterwards. A second group of mice received four ip injections of [ 3 H]-thymidine at 6-h intervals on the 1st day of pregnancy and were killed on the 2nd, 5th or 6th day of pregnancy. A third group of virgin mice in estrus received [ 3 H]-thymidine ip four times at 6-h intervals and was killed 96 h after the first injection. Radioautographs of the uteri showed that few endometrial stomal cells were labelled on the 1st and 2nd day of pregnancy. Although many decidual cells incorporated thymidine on the 5th and 6th day of pregnancy in pulse-labelled animals, only few labelled decidual cells were found on the 5th and 6th day of pregnancy in animals that received several injections of thymidine on the 1st and 2nd day of pregnancy. These results indicate that the antimesometrial decidual cells that develop at the beginning of pregnancy are mostly of local origin. The short-term migration of extraneous cells into the uterus to participate in decidualization is not supported by these data. (author) [pt

Decidual tissue growth and regression in the guinea pig: regulation by uterine blood flow and relation to circulating progesterone concentrations.

The role of uterine blood flow (UBF) in the modulation of experimentally induced decidua formation was assessed in mature guinea pigs. The response to endometrial trauma, as indexed by uterine weight changes, was dependent upon the type of stimulus used, with deciduogenic effectiveness as follows: saline = oil = knife scratch less than scissor cut. Both the knife scratch and scissor cut techniques induced elevations in UBF compared with control values. Neither uterine weight nor UBF increased when trauma was applied to unresponsive uteri, indicating that inflammation was not the cause of uterine hyperemia. Uterine weight increased from basal levels on the day of trauma (i.e. day 5 of the estrous cycle) to a maximal weight between days 10 and 12 posttrauma. Maximal growth of the induced decidua occurred under conditions of elevated UBF. Subsequently, UBF declined between days 10 and 15 posttrauma, preceding the associate resorption of the induced decidua. During the period of decidua growth, serum progesterone levels were elevated compared with those in control animals. These data indicate that experimentally induced decidua formation in the guinea pig is associated with uterine hyperemia and increased corpus luteum activity, both of which are necessary for proper endometrial differentiation. It is hypothesized that these events mimic the uterine hyperemia associated with blastocyst implanplantation and early placentation in this species.

This paper presents the results of an investigation of Asoka Aristha, an indigenous medicine used in rural Sri Lanka for menstrual disorders. This investigation was part of a broader evaluation of ayurvedic drugs aimed at establishing the botanic identity of drug ingredients, establishing possible modes of action, and identifying the chemical constituents responsible for the drug effects. It is projected that the results of this research can be used to standardize ayurvedic drugs and optimize the quality and production procedures. Asoka Aristha, a fermented potion composed largely of Asoka bark, is produced on a large scale by the state-owned Ayurvedic Drugs Corporation. It has been indicated for women in cases of menorrhagia, metrorrhagia, leukorrhea, primary amenorrhea, general menstrual disorders, and skin disorders. 3 types of experiments are projected to evaluate the biologic activity of Asoka Aristha: measurement of the occurrence of cornification of the uterus epithelium in hypophysectomized rats after administration of the drug to determine the estrogenic mode of action, in vitro measurement of the direct uterine activity of the drug to determinme the oxytocic effect, and testing of the inhibiting properties of the drug in prostaglandin synthetase enzyme reactions in vitro. Experiments carried out on rat uteri so far seem to rule out the mechanism based on oxytocic action. It is urged that clinical trials on the therapeutic effect of Asoka Aristha be carried out in Sri Lanka.
