    This paper presents the successful use of a non-surgical, transcervical uterine lavage technique for the treatment of uterine infection-induced infertility in three female large cats. We developed a non-surgical uterine lavage technique, which allowed repeated flushing of the uterine lumen and installation of therapeutic antibiotics. The entire procedure was performed under general anaesthesia (duration of anesthesia ranged from 40 to 70 min). It was successfully applied in a Sumatran tiger (Panthera tigris sumatrae), a Corbett tiger (Panthera tigris corbetti) and an Amur leopard (Panthera pardus orientalis). The tigers were treated only once, whereas the leopard received four uterine treatments, due to re-infection after mating. Decisions to conduct uterine treatments were based on detection of uterine fluid during previous transrectal ultrasound examinations. The catheter was guided into the vagina, with the aid of an endoscope, passing the urethra, and then into the uterus, with the aid of transrectal ultrasonography. Both uterine horns were separately flushed with approximately 300 mL of cell medium M199, followed by an antibiotic infusion. Upon ultrasonographic re-examination, the topical uterine treatments resulted in an apparent decline in the inflammatory and/or degenerative processes. The Corbett tiger had the most severe uterine alterations, in addition to an aseptic pyometra. As a result, she was treated 1 month prior to ovariohysterectomy (in order to reduce the surgical risk). The Sumatran tiger was artificially inseminated twice after hormone-induced estrus, and the Amur leopard expressed a spontaneous estrus and re-initiated mating behaviour. PMID:16530816

    In the mare, the low-volume uterine lavage technique allows for bacterial sampling of the entire uterine lumen and is usually performed after obtaining the traditional double-guarded endometrial swab for aerobic culture and cytology and before procurement of an endometrial biopsy sample during a breeding soundness examination. The purpose of this study was to explore the potential effects of the low-volume lavage on the endometrial biopsy classification and polymorphonuclear cell (PMNs) infiltration in the context of a breeding soundness examination. Fourteen light horse mares of mixed breed, age 7 to 21 years, with known reproductive history, were included in the study, matched by age and reproductive history, and then divided into treatment and control groups. Transrectal palpation and ultrasonography, endometrial swabbing, and the first endometrial biopsy were performed in all mares. Low-volume uterine lavage was performed in the treatment group but not the control group. After either the lavage or a 15-minute rest, a second endometrial biopsy was obtained from both the control and treatment groups. Endometrial swabs and effluent from the low-volume lavages were submitted for aerobic culture and sensitivity. Biopsy samples were fixed in Bouin's solution for 24 hours, processed, stained with hematoxylin and eosin, and then viewed under bright light microscopy. Additional staining with anti-neutrophil elastase antibody (ab68672) was performed for indirect immunohistochemistry. All samples were interpreted by a blinded observer. When the first (pre-uterine lavage) and second (post-uterine lavage) biopsies were compared using a mixed-effects logistic regression, there was no difference in endometrial biopsy classification (P = 0.74), presence of PMNs in blood vessels (P = 0.728), or infiltration of PMNs in the tissue (P = 0.934) between the treatment and control groups. In this study, the low-volume uterine lavage did not affect the endometrial biopsy

    Subclinical endometritis affects approximately 30% of lactating dairy cows, causing significant economic losses to the dairy industry. Yet, there is no efficient treatment available for this condition. The present study examines the effect of uterine lavage in clinically normal cows with sterile saline solution at 30 days in milk (DIM) on the percentage of polymorphonuclear cells (PMNs) detected with endometrial cytology as an indicator of subclinical endometritis. It was hypothesized uterine lavage would be a technique to reduce the number of PMNs in the uterus, and hence be beneficial for cows affected by subclinical endometritis. Cytology samples were taken by low-volume flushing from 50 Holstein Friesian cows on 30 and 40 DIM. On Day 30, cows were clinically examined and randomly assigned into a treatment and control group. In the treatment group, the cytology sampling on Day 30 was immediately followed by uterine lavage with 500-600 mL of sterile physiological saline (35-40°C). Cytology sampling was repeated in all cows at 40 DIM. Lactation numbers >2, peripheral progesterone concentrations >1 ng/mL and uterine lavage at 30 DIM all were significantly associated with lesser PMN percentages at 40 DIM (P=0.0041; 0.0187 and 0.0043, respectively). Uterine lavage might, therefore, be a useful and practical method to decrease the number of PMNs in the uterus of cattle. Results from the current study can be used as preliminary data for designing in depth therapeutic protocols for treatment of subclinical endometritis in cattle. PMID:25956200

    Endometritis constitutes a major problem in the management of broodmares; hence, diagnostic tests with a high sensitivity and specificity are highly appreciated. The aim of this study was to compare the results from endometrial, cytologic, and bacteriologic examinations obtained by a newly developed, double-guarded, flushing technique versus standard diagnostic tests, the double-guarded swab and biopsy. The described double-guarded flush technique requires the use of a disposable uterine flushing tube, a sanitary sleeve, a sterile steel speculum, and a 250 mL fluid bag. Endometrial biopsies, swabs, and low-volume lavage samples were obtained from 34 research mares at six different time points in four estrous cycles and were evaluated cytologically and bacteriologically. Endometrial biopsies from the first cycle (n = 34) were examined for the presence of polymorphonuclear neutrophils (PMNs) in the stratum compactum and stratum spongiosum and used as a gold standard for calculation of diagnostic sensitivity and specificity. In all samples, Escherichia coli was most frequently isolated (lavage, 30%; swab, 21%; and biopsy, 12%) followed by β-hemolytic streptococci (lavage, 11%; swab, 8%; and biopsy, 7%). Positive cytology was less likely to occur when E coli was isolated from the diagnostic tests compared with the growth of β-hemolytic streptococci. Isolation of pathogens from uterine samples was highly associated with the presence of PMNs in the stratum compactum and straum spongiosum on histology. Using the presence of PMNs in the tissue specimens as the gold standard for diagnosing endometritis, the sensitivity of low-volume lavage culture was 0.75 and the specificity was 0.72. In conclusion, the double-guarded, low-volume, lavage technique was a rapid and accurate method for diagnosing mares with endometritis, and the risk of false-positive samples is considered to be minimal compared with other flushing techniques described.

    Purpose Type II ovarian cancer (OC) and endometrial cancer (EC) are generally diagnosed at an advanced stage, translating into a poor survival rate. There is increasing evidence that Müllerian duct cancers may exfoliate cells. We have established an approach for lavage of the uterine cavity to detect shed cancer cells. Patients and Methods Lavage of the uterine cavity was used to obtain samples from 65 patients, including 30 with OC, five with EC, three with other malignancies, and 27 with benign lesions involving gynecologic organs. These samples, as well as corresponding tumor tissue, were examined for the presence of somatic mutations using massively parallel sequencing (next-generation sequencing) and, in a subset, singleplex analysis. Results The lavage technique could be applied successfully, and sufficient amounts of DNA were obtained in all patients. Mutations, mainly in TP53, were identified in 18 (60%) of 30 lavage samples of patients with OC using next-generation sequencing. Singleplex analysis of mutations previously determined in corresponding tumor tissue led to further identification of six patients. Taken together, in 24 (80%) of 30 patients with OC, specific mutations could be identified. This also included one patient with occult OC. All five analyzed lavage specimens from patients with EC harbored mutations. Eight (29.6%) of 27 patients with benign lesions tested positive for mutations, six (75%) as a result of mutations in the KRAS gene. Conclusion This study proved that tumor cells from ovarian neoplasms are shed and can be collected via lavage of the uterine cavity. Detection of OC and EC and even clinically occult OC was achieved, making it a potential tool of significant promise for early diagnosis. PMID:26552420

    The objective of the present study was to evaluate the beneficial effect of hCG injected immediately after mating in Arabian barren mares treated with uterine lavage and oxytocin. Arabian barren mares (n=36) with PMIE were subjected to detailed clinical examinations including palpation per rectum, vaginoscopy, and cytological examination. After mating the 36 mares were randomly divided into four groups. The mares in group 1 (n=10) were immediately after breeding injected with hCG 3,000 IU IM. Uterine lavage with 1L of N-saline containing 4 million IU of crystalline penicillin and 4 g of streptomycin sulphate was performed 4h after breeding. Then mares received two injections of oxytocin 40 IU IM 2h apart after 6h of mating. Mares in group 2 (n=10) treated with uterine lavage and oxytocin as group 1. While mares in group 3 (n=10) received uterine lavage only. A control group (n=6) as group 4 did not received any treatment. The results of clinical examination indicated that 69.4% of PMIE mares were harboring severe endometritis and 30.6% with a moderate form of endometritis. Significant (P<0.01) increase in lymphocytes were founded in barren mares included in this study. Higher pregnancy rate (P<0.01) was founded in Arabian barren mares 80% injected with hCG immediately after breeding and uterine lavage and oxytocin. No significant difference was found in mares received uterine lavage and oxytocin and uterine lavage only. In a conclusion, administration of hCG immediately after mating and intrauterine lavage containing antibiotics performed 4h and two injections of oxytocin 40 IU IM 2h apart after 6h of mating had improved fertility of Arabian barren mares.

    The aim of this study was to determine the presence of Tritrichomonas foetus in two dairy herds on the Altiplano Cundiboyacense. Twenty-one low-volume uterine lavages from cows with a history of reproductive problems in two dairy herds located in the municipality of Sibaté (Cundinamarca) and Ventaquemada (Boyacá) were evaluated. In the first herd, 10 cows were sampled and in the second, 11 cows, based on three inclusion criteria. The uterine lavages were obtained through infusion of physiological saline solution into the uterine body. The samples were centrifuged and seeded in Tritrichomonas basal medium for 10-15 days at 37 ºC. The protozoa were evaluated on the day of sampling and 10 and 15 days after incubation by means of direct viewing under a dark-field microscope. Positive samples were stained with Wright and Lugol to identify the morphological characteristics. This study showed that T. foetus was present in 61.8% of the animals sampled. The determination that T. foetus was present in 61.8% of the samples analyzed is a significant finding given that in the herds evaluated, this agent had not previously been diagnosed. PMID:23070427

    Productivity rates directly depend on the fertility of a herd, which in turn can be influenced by many factors. Semen deposited in the female reproductive tract is foreign to the body and, in response to this invasion, produces an inflammatory reaction, which is characterized by rapid infusion of polymorphonuclear (PMN) cells. Techniques to obtain an endometrial sample are usually invasive and can mask the true inflammatory response. Ultrasound is a noninvasive technique and can contribute to the diagnosis of postartificial insemination (AI) inflammatory response in cattle. The present study was divided into two experiments. The aim of experiment 1 was to compare two methods of endometrial cytology collection, uterine cytobrush (UC) and uterine lavage (UL), and their effects on uterine hemodynamics that provide information about blood flow. The two methods were evaluated by Doppler ultrasound using the spectral and color modes. For that purpose, 19 Nellore cows were synchronized for timed AI and subjected to UC (n = 9) or UL (n = 10). The techniques were performed 4 hours after AI. The results showed that both techniques allow collection of a good quality sample and with enough PMN cells to perform counting. More PMN cells were obtained by UL than UC. There was no difference in uterine blood flow between the UC and UL groups in any of the periods evaluated (34 hours before and 4, 24, and 48 hours after collection of uterine sample). On the basis of results of experiment 1, the effect of UL on fertility was studied in experiment 2. A total of 128 Nellore cows were synchronized for TAI; 35 cows were subjected to endometrial cytology by UL 4 hours after AI, and 93 were not submitted to any procedure (control). Pregnancy diagnosis was performed by transrectal ultrasound 30 days after AI. Pregnancy rates did not differ between UL (54.29%) and control (56.99%) groups. The results of this study showed that UL allows the collection of more representative cells of

    Aim. To describe a new technique of uterine manipulation in laparoscopic management of pelvic cancers. Material and Methods. We used a novel uterine hitch technique in 23 patients from May 2008 to October 2008. These patients underwent pelvic oncologic surgery including laparoscopic radical hysterectomy (n = 7), laparoscopic anterior resection (n = 4), laparoscopic abdominoperineal resection (n = 3), laparoscopic posterior exenteration (n = 4), or laparoscopic anterior exenteration (n = 5). The uterus was hitched to the anterior abdominal.wall by either a single suture in the fundus or by sutures through the round ligaments. Results. The uterine hitch technique was successfully accomplished in all procedures. It was performed in less than 5 minutes in all cases. It obviated the need for vaginal manipulation. An extra port for retraction could be avoided. There were no intraoperative complications. Conclusion. A practical, cheap and reproducible method for uterine manipulation, during pelvic oncologic surgery is described. It improves the stability of the uterus and also obviates the need for keeping an additional assistant for vaginal manipulation in any of the procedures. PMID:22091356

  10. Uterine Closure in Cesarean Delivery: A New Technique

    Fear of scar rupture is one of risks involved in a post caesarean pregnancy. This had led to an increased rate of repeat cesarean delivery in today's times. Closure of the uterine incision is a key step in cesarean section, and it is imperative that an optimal surgical technique be employed for closing a uterine scar. This technique should be able to withstand the stress of subsequent labor. In the existing techniques of uterine closure, single or double layer, correct approximation of the cut margins, that is, decidua-to-decidua, myometrium to myometrium, serosa to serosa is not guaranteed. Also, there are high chances of inter surgeon variability. It was felt that if a suturing technique which ensures correct approximation of all the layers mentioned above with nil or minimal possibility of inter operator variability existed, there will not be any thinning of lower segment caesarean section (LSCS). Further, a scarred uterus repaired in this manner will be able to withstand the stress of labor in future. We hereby report a new technique for uterine closure devised by us, which incorporates a continuous modified mattress suture technique as a modification of the existing surgical technique of uterine closure.

    Uterine fibroids occur in approximately 50% of women over the age of 40 years, and an estimated 50% of those are symptomatic. Menorrhagia is the most common symptom and the primary indication for treatment, although bulk symptoms often occur and can be treated. Pharmacotherapy is typically inadequate unless it can be expected to successfully bridge to menopause or allow for a less-invasive intervention. However, hormonal therapies have risks. Hysterectomy is still the most commonly performed procedure for symptomatic fibroids and has the lowest rate of reintervention (compared with myomectomy or uterine artery embolization [UAE]), but rates of more serious complications are higher and patient satisfaction and ability to return to normal activities may also be less favorable. Myomectomy is not necessarily less morbid than hysterectomy and may have a greater failure rate than UAE. Techniques and devices vary with little standardization, and operator experience is crucial to success. The largest studies of UAE show very low rates of serious complications and rapid recovery. UAE significantly improves symptoms related to uterine fibroids in 85%-90% of patients. Herein, this article will discuss the nature of fibroids and their diagnosis, pharmacotherapy, surgical treatment, and nonsurgical interventional treatment, including UAE and magnetic resonance-guided focused ultrasound.

    Pediatric patients with pulmonary alveolar proteinosis require whole lung lavage to clear the accumulation of lipoproteinaceous material within the alveoli, to maintain respiratory function. Anesthesia for this presents a challenge due to preexisting respiratory failure, and the small diameter and length of the pediatric airway, which is often unable to accommodate existing one-lung isolation and ventilation equipment. Novel techniques to facilitate lung lavage on seven occasions are described and placed in the context of the existing literature to date. PMID:25664978

    Abstract Peritoneal lavage and dialysis is an approach to treat necrotizing acute pancreatitis as it removes dialyzable toxins and reduces severe metabolic disturbances. Successful catheter implantation is important for delivering adequate peritoneal lavage and dialysis. The aim of the present study was to describe a new modified percutaneous technique for the placement of peritoneal dialysis catheters and assess the effectiveness and safety of peritoneal lavage and dialysis used for treatment of necrotizing acute pancreatitis. We conducted a retrospective data review of 35 patients of necrotizing acute pancreatitis from January 2010 to December 2014 in Jilin City Central Hospital and The First Affiliated Hospital of ZheJiang University. In total, 18 patients underwent peritoneal lavage and dialysis after inserting catheters by our new technique (group A), whereas 17 patients underwent ultrasound-guided percutaneous catheter drainage (group B). By analyzing the patients’ data, the drainage days and mean number of hours between the debut of the symptoms and the hospital admission were lower in group A (P < 0.05, P < 0.05, respectively). The complication rate of 5.6 and 17.6%, respectively (P = 0.261), and a mortality rate of 16.7 and 5.9% for each group, respectively (P = 0.316). Likewise, hospitalization time was similar for the group A: 31 ± 25.3 days compared with 42.8 ± 29.4 days in the group B (P = 0.211). Peritoneal lavage and dialysis can be used in necrotizing acute pancreatitis, and our new modified percutaneous technique offers the same complication and mortality rate as ultrasound-guided drainage but with a shorter drainage days.

    The quality of the primary care of Gustilo-Anderson (GA) type IIIB and IIIC extremity injuries is crucial to the success of the limb salvage procedure. This article provides a compilation of consistent, but often controversially discussed aspects of initial debridement, modern techniques of lavage and wound closure, in addition to current issues on the application of antibiotics and antiseptics, based on our own experiences and the latest literature. The following points should be stressed. Severe extremity injuries with gross contamination (GA IIIA, B, and C) will still be associated with an infection rate of up to 60 %. The initial debridement should be performed as soon as an experienced trauma surgeon is available. Tissue that is definitely avital will have to be removed, whereas traumatized but potentially surviving tissue will have to be re-evaluated during a second-look operation after 36-48 h. Given a high enough level of contamination, biofilms will form after as few as 6 h. The perioperative antibiotic prophylaxis has to be initiated early and should be continued for at least 24 h (GA I/II) or up to 5 days (GA III). In cases of bacterial contamination, wound irrigation will be useful with additives such as polyhexanide, octenidine or superoxidized water. Rinsing of the wound should be performed with 3-9 L and only slight manual pressure (no jet lavage). The definitive primary closure of a wound should be achieved in the initial operation, but only in the case of certain "decontamination" and overall vitality of the wound (GA I and II). In the presence of high-grade injuries, a temporary vacuum sealing technique can be used until the earliest possible definitive plastic surgical wound closure. PMID:27160730

    Endometritis is the most important cause of infertility in barren mares. The quick method of endometrial cytology (EC) has a relatively high reliability in diagnosing endometrial inflammation in the mare. For reliable cytological results, a collection technique that yields many well-preserved cells representative of a large uterine surface area without causing harm to the reproductive tract is required. The aim of the study was to compare three usually employed techniques for collection of endometrial and inflammatory cells (guarded cotton swab, uterine lavage, and cytobrush) in chronically infertile mares. Twenty Standardbred mares were used. In each mare, samples for EC were collected, first by a cotton swab (DGS), then by a cytobrush (CB), and finally by low volume flush (LVF). The slides were stained using the Diff Quick stain. The following parameters were assessed for each tested technique: background content of the slides; quality of the cells harvested; total cellularity; neutrophils; ratio PMN/uterine epithelial cells; inflammatory cells; vaginal epithelium cells. Categorical variables were compared using contingency tables and Pearson Chi-square tests, whereas continuous variables were compared using one-way analysis of variance (ANOVA); P<0.05 was considered significant. Samplings by DGS and CB resulted easy and quick to perform via a single operator in all cases. LVF was performed easily, but required the presence of 2-3 players and took more time. The background content of the slides prepared by DGS appeared proteinaceous, slides prepared by LVF appeared contaminated by red blood cells or debris, whereas slides prepared by CB appeared clear. All smears showed a good total cellularity. The CB yielded significantly more cells (P<0.0001) than DGS and LVF. The DGS produced significant more cells than LVF (P<0.0001). The DGS produced significantly more (P=0.003) intact cells than CB and LVF. Distorted cells were significantly (P=0.001) more frequent in

    The diagnosis and management of pneumonia are limited by the use of culture-based techniques of microbial identification, which may fail to identify unculturable, fastidious, and metabolically active viable but unculturable bacteria. Novel high-throughput culture-independent techniques hold promise but have not been systematically compared to conventional culture. We analyzed 46 clinically obtained bronchoalveolar lavage (BAL) fluid specimens from symptomatic and asymptomatic lung transplant recipients both by culture (using a clinical microbiology laboratory protocol) and by bacterial 16S rRNA gene pyrosequencing. Bacteria were identified in 44 of 46 (95.7%) BAL fluid specimens by culture-independent sequencing, significantly more than the number of specimens in which bacteria were detected (37 of 46, 80.4%, P ≤ 0.05) or "pathogen" species reported (18 of 46, 39.1%, P ≤ 0.0001) via culture. Identification of bacteria by culture was positively associated with culture-independent indices of infection (total bacterial DNA burden and low bacterial community diversity) (P ≤ 0.01). In BAL fluid specimens with no culture growth, the amount of bacterial DNA was greater than that in reagent and rinse controls, and communities were markedly dominated by select Gammaproteobacteria, notably Escherichia species and Pseudomonas fluorescens. Culture growth above the threshold of 10(4) CFU/ml was correlated with increased bacterial DNA burden (P < 0.01), decreased community diversity (P < 0.05), and increased relative abundance of Pseudomonas aeruginosa (P < 0.001). We present two case studies in which culture-independent techniques identified a respiratory pathogen missed by culture and clarified whether a cultured "oral flora" species represented a state of acute infection. In summary, we found that bacterial culture of BAL fluid is largely effective in discriminating acute infection from its absence and identified some specific limitations of BAL fluid culture in the

Culture growth above the threshold of 104 CFU/ml was correlated with increased bacterial DNA burden (P < 0.01), decreased community diversity (P < 0.05), and increased relative abundance of Pseudomonas aeruginosa (P < 0.001). We present two case studies in which culture-independent techniques identified a respiratory pathogen missed by culture and clarified whether a cultured “oral flora” species represented a state of acute infection. In summary, we found that bacterial culture of BAL fluid is largely effective in discriminating acute infection from its absence and identified some specific limitations of BAL fluid culture in

    The article serves to review the literature on the human uterine cervix based on a new distension technology named functional luminal imaging probe. This technology was originally developed to study the biomechanical competence of the gastro-esophageal junction where it provides a geometric profile of the lumen during distension, which can be related to sensory data. We searched and reviewed publications on cervical distention from 2002. The functional luminal imaging probe technology has been used for studying the mechanical and mechano-sensory properties of the cervix in non-pregnant women. In early pregnant women and in term pregnant women, the technique provides geometric measurements from the whole cervical canal during distension, which changes dramatically during pregnancy. Furthermore, it has been demonstrated that the technique predicts the outcome of labor induction better than the Bishop score does. The functional luminal imaging probe technology has potential as a research tool as well as for clinical use in gynecology and obstetrics. PMID:26946059

  1. Novel agents and treatment techniques to enhance radiotherapeutic outcomes in carcinoma of the uterine cervix

    PubMed Central

    2016-01-01

    Background Survival of patients with locally advanced carcinoma cervix (LACC) using the current standard of concurrent chemo-radiotherapy (CCRT) has reached a plateau over the last two decades. Loco-regional failure in first two years of treatment completion and distant metastasis in the subsequent years has put the survival curves at a halt. Strategies of induction and adjuvant chemotherapy have yielded little as has any advancement in techniques of delivery of radiation therapy. This article aims at discussing the current existing literature as well as promising novel strategies to enhance radiotherapeutic outcomes in carcinoma of the uterine cervix. Methods The review of English literature included phase I-III trials evaluating either a novel agent, novel application/modifications of an existing treatment regimen or an innovative treatment technique. The studies have been divided in to subsections with summary of most important findings at the end of each section. Results Despite CCRT being the ‘gold standard’ treatment, several issues like optimum drug combination, schedule of drug delivery, combination with molecular targeted agents etc. remain undefined. Taxane, topoisomerase and gemcitabine based regimen needs to be further explored and compared with cisplatin based CCRT regimen. Several approaches like local delivery of cytotoxic agents, use of nano-medicine with CCRT are appearing on horizon with promises for the future. Therapies need to be designed based on the human papillomavirus titers of the patients and incorporation of radiosensitizers as an effective way of palliation with short course of radiotherapy may further enhance the radiotherapeutic outcomes. Conclusions The results of the studies with novel agents and treatment techniques appear promising. Further research in this arena including incorporation of cost-effectiveness analysis and quality of life issues in future trial designs are warranted. PMID:26904571

    Postpartum haemorrhage is a leading cause of global maternal mortality and morbidity, accounting for 25-30% of all maternal deaths, and 75-90% of these casualties result from uterine atony. Uterine compressive sutures are a well established measure for control of haemorrhage following atonic postpartum haemorrhage, when medical and nonmedical interventions fail. Here, we are reporting a case of secondary infertility in a 24-year-old lady who had undergone an elective caesarean section for central placenta previa in her first pregnancy. She had massive postpartum haemorrhage, for which B-Lynch suture and vessel ligation were done. Subsequently, she failed to conceive for 4 years. This was because of severe pelvic adhesions and uterine deformation which were found intraoperatively, as a consequence of previous use of B-Lynch suture. As no definitive treatment could be offered to her, we suggested her to go for adoption. PMID:24959485

    Background: Uterine arteriovenous malformation is a rare but potential life-threatening source of bleeding. A high index of suspicion and accurate diagnosis of the condition in a timely manor are essential because instrumentation that is often used for other sources of uterine bleeding can be lead to massive hemorrhage. Case: We describe here a case of uterine arteriovenous malformation. A 32-year-old woman presented abnormal vaginal bleeding following the induced abortion. A diagnosis of uterine arteriovenous malformation made on the basis of Doppler ultrasonraphy was confirmed through pelvic angiography. The embolization of bilateral uterine arteries was performed successfully. Conclusion: Uterine arteriovenous malformation should be suspected in patient with abnormal vaginal bleeding, especially who had the past medical history incluing cesarean section, induced abortion, or Dillation and Curethage and so on. Although angiography remains the gold standard, Doppler ultrasonography is also a good noninvasive technique. The transcatheter uterine artery embolization offers a safe and effective treatment PMID:24639742

    Uterine fibroids are a major cause of morbidity in women of a reproductive age (and sometimes even after menopause). There are several factors that are attributed to underlie the development and incidence of these common tumors, but this further corroborates their relatively unknown etiology. The most likely presentation of fibroids is by their effect on the woman’s menstrual cycle or pelvic pressure symptoms. Leiomyosarcoma is a very rare entity that should be suspected in postmenopausal women with fibroid growth (and no concurrent hormone replacement therapy). The gold standard diagnostic modality for uterine fibroids appears to be gray-scale ultrasonography, with magnetic resonance imaging being a close second option in complex clinical circumstances. The management of uterine fibroids can be approached medically, surgically, and even by minimal access techniques. The recent introduction of selective progesterone receptor modulators (SPRMs) and aromatase inhibitors has added more armamentarium to the medical options of treatment. Uterine artery embolization (UAE) has now been well-recognized as a uterine-sparing (fertility-preserving) method of treating fibroids. More recently, the introduction of ultrasound waves (MRgFUS) or radiofrequency (VizAblate™ and Acessa™) for uterine fibroid ablation has added to the options of minimal access treatment. More definite surgery in the form of myomectomy or hysterectomy can be performed via the minimal access or open route methods. Our article seeks to review the already established information on uterine fibroids with added emphasis on contemporary knowledge. PMID:24511243

    Bronchoalveolar lavage (BAL) is a simple but valuable and typically performed technique commonly used for studying the pathogenesis of lung diseases such as asthma and COPD. Cell counts can be combined with new methods for examining inflammatory responses, such as ELISA, Flow cytometric analysis, immunohistochemistry, quantitative polymerase chain reaction, and HPLC to assess cellular expression for inflammatory cytokines and growth factor. Here we describe a basic procedure to collect BAL fluid and digest lung tissue for assessing a number of pulmonary components.

    Persistence of free fluid in the uterine lumen of bitches with endometrial hyperplasia appears to be diagnostic for mating-induced endometritis and is associated with reduced chances of pregnancy. This study investigated the possibility that reduced fertility might be associated with an effect of uterine fluid on sperm. Uterine lavage fluid was collected pre- and post-insemination from normal bitches without ultrasonographically-detectable luminal fluid (n=4), and previously non-pregnant bitches with endometrial hyperplasia and luminal fluid (n=4). Concentrations of polymorphonuclear neutrophils (PMNs) were measured and the effect of the fluid on the attachment of spermatozoa to the uterine epithelium was studied using medium (M) 199 as a control. To elucidate whether any effect was accounted for by the presence of PMNs, attachment was also measured in M199 with PMNs added at the concentration found in lavage fluid. Pre-insemination lavage fluid from both groups contained low concentrations of PMNs which increased post-insemination; the increase was larger for bitches with uterine fluid. Compared with M199 controls, lavage fluid reduced the attachment of spermatozoa; fluid from bitches with endometrial hyperplasia and uterine fluid had a greater effect than normal bitches, and post-insemination fluid had a greater effect than pre-insemination fluid. Spermatozoal attachment was reduced by a similar magnitude for M199 with added PMNs, although post-insemination fluid from bitches with endometrial hyperplasia reduced attachment more than M199 with added PMNs. Poor fertility in bitches with uterine luminal fluid might be partially associated with impaired attachment of spermatozoa to uterine epithelium, mediated principally, but not solely, by PMN influx into the uterine lumen.

    This study's objective was to test the new drainage apparatus called enclosed passive infraversion lavage-drainage system (EPILDS) in the treatment of bile leakage and pancreatic fistula Post Pancreatoduodenectomys. The EPILDS device has a design of a siphon. The inlet bag that contains the rinse liquid is put lower than the abdominal lacuna to be washed but higher than the outlet bag. The hydrostatic pressure difference between the inlet and outlet bags constitutes the driving force of the flow. The three-way cock valves are installed in the inlet and outlet tubes to facilitate the washing of occluded tubes. Two side by side Penrose drainage tubes were placed during the operation. One tube passed through the posterior side of pancreatico-jejunal and biliary-jejunal anastomoses, right paracolic gutter, and exited through an opening made in the right lower abdomen. Second tube came from the smaller sac, went through the anterior side of pancreatico-jejunal and biliary-jejunal anastomoses, and exited through an opening made in the left upper abdomen. Using this system, we successfully treated two patients. Both inlet and outlet volumes were observed to verify that the outlet exceeds the inlet volume. In conclusion, EPILDS has a simple and practical design. It changes the active washing process into a passive one, in which the input is controlled by the exiting fluid. This is the effective and safe system for treatment of severe bile leakage and pancreatic fistula at the early postoperative stage. PMID:24006154

    Uterine factor infertility is either due to congenital malformation or acquired. Most women with uterine factor infertility have no chance to become genetic mothers, except by the use of gestational surrogacy. The logical but radical approach for treatment would be replacement of the unfunctional or absent uterus. Uterine transplantation could allow these women to become both genetic and gestational mothers. The present work reviews the existing literature on the history and recent development around this topic. We also briefly describe a newly developed model for heterotopic uterine transplantation in the mouse, in which pregnancies have been accomplished. Some specific issues that are required to be solved prior any further attempts to transplant the uterus in humans are also addressed. PMID:12860325

    Quantification of the differential cell count and total number of cells recovered from the lower respiratory tract by bronchoalveolar lavage is a valuable technique for evaluating the alveolitis of patients with inflammatory disorders of the lower respiratory tract. The most commonly used technique for the evaluation of cells recovered by lavage has been to concentrate cells by centrifugation and then to determine total cell number using a hemocytometer and differential cell count from a Wright-Glemsa-stained cytocentrifuge preparation. However, we have noted that the percentage of small cells present in the original cell suspension recovered by lavage is greater than the percentage of lymphocytes identified on cytocentrifuge preparations. Therefore, we developed procedures for determining differential cell counts on lavage cells collected on Millipore filters and stained with hematoxylin-eosin (filter preparations) and compared the results of differential cell counts performed on filter preparations with those obtained using cytocentrifuge preparations. When cells recovered by lavage were collected on filter preparations, accurate differential cell counts were obtained, as confirmed by performing differential cell counts on cell mixtures of known composition, and by comparing differential cell counts obtained using filter preparations stained with hematoxylin-eosin with those obtained using filter preparations stained with a peroxidase cytochemical stain. The morphology of cells displayed on filter preparations was excellent, and interobserver variability in quantitating cell types recovered by lavage was less than 3%.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6385789

    Introduction Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery. Aim This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis. Material and methods We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7%) patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique); 21 (30%) patients underwent peritoneal laparoscopic lavage; 4 (5.7%) patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6%) patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy. Results The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients). In the LPL group the morbidity rate was 33.3%. Conclusions Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage. PMID:27458487

    Purpose To evaluate the effect of bowel interposition on assessing procedure feasibility, and the usefulness and limiting conditions of bowel displacement techniques in magnetic resonance imaging-guided high-intensity focused ultrasound (MR-HIFU) ablation of uterine fibroids. Materials and Methods Institutional review board approved this study. A total of 375 screening MR exams and 206 MR-HIFU ablations for symptomatic uterine fibroids performed between August 2010 and March 2015 were retrospectively analyzed. The effect of bowel interposition on procedure feasibility was assessed by comparing pass rates in periods before and after adopting a unique bowel displacement technique (bladder filling, rectal filling and subsequent bladder emptying; BRB maneuver). Risk factors for BRB failure were evaluated using logistic regression analysis. Results Overall pass rates of pre- and post-BRB periods were 59.0% (98/166) and 71.7% (150/209), and in bowel-interposed cases they were 14.6% (7/48) and 76.4% (55/72), respectively. BRB maneuver was technically successful in 81.7% (49/60). Through-the-bladder sonication was effective in eight of eleven BRB failure cases, thus MR-HIFU could be initiated in 95.0% (57/60). A small uterus on treatment day was the only significant risk factor for BRB failure (B = 0.111, P = 0.017). Conclusion The BRB maneuver greatly reduces the fraction of patients deemed ineligible for MR-HIFU ablation of uterine fibroids due to interposed bowels, although care is needed when the uterus is small.

    1985-01-01

    Bronchoalveolar lavage has emerged as a useful technique for the study of pulmonary interstitial disorders. Several types of information are provided by the evaluation of lavage fluid. First, the identification of cellular constituents helps to separate inflammatory processes in which lymphocytes predominate (for example, sarcoidosis, hypersensitivity pneumonitis, and berylliosis) from those in which neutrophils or macrophages predominate (for example, idiopathic pulmonary fibrosis and histiocytosis X). Second, the cells removed during lavage can be studied for their immune properties and function; tested with specific antigens, in diseases such as berylliosis and hypersensitivity pneumonitis; and examined for the presence of unique surface antigens with monoclonal antibodies (for example, histiocytosis X). Third, in conjunction with scanning electron microscopy and electron probe analysis, lavage makes possible the identification of inorganic particles in alveolar macrophages of patients with pneumoconiotic lung disease. Finally, although lavage is still an investigative procedure for most pulmonary disorders, it has an established role in the diagnosis of opportunistic infections in the immunocompromised patient.

    PurposeTo evaluate a modified superior hypogastric nerve block (SHNB) to reduce pain after uterine artery embolization (UAE) compared to epidural anesthesia.Materials and methodsIn this retrospective study, the amount of opiate drugs needed after UAE was compared between SHNB and epidural anesthesia. Eighty one consecutive women (mean age: 43.67 years) were in the SHNB group and 27 consecutive women (mean age: 43.48 years) treated earlier at the same institution in the epidural anesthesia group. UAE was performed from a unilateral femoral artery approach using a 4F catheter. 500–700 or 700–900 μm trisacryl gelatine microspheres were used as embolic agents. The SHNB was performed by advancing a 21G from the abdominal wall below the umbilicus to the anterior portion of the 5th vertebral body. For optimal guidance a cranio-caudal tilt of 5°–15° was used. On a lateral view the correct contrast distribution in front of the vertebral body is confirmed. Then 20 ml local anesthesia (ropivacain 0.75 %) is injected. In case of an asymmetric right–left distribution the needle was repositioned.ResultsAll SHNB were successful without severe complications. The mean time for the SHNB was 4 min 38 s (2 min 38 s–9 min 27 s). The needle was repositioned in average 0.87 times. The opiate dose for the SHNB group was 19.33 ± 22.17 mg which was significantly lower. The average time to receive an opiate drug after SHNB was 4 h 41 min.ConclusionThe SHNB is a safe and minimally time-consuming way to reduce pain after UAE especially within the first 4 h.

    Introduction The minilaparotomy is considered to be a safe and effective alternative to laparoscopy and abdominal laparotomy in myomectomy cases. Aim To perform a retrospective analysis of pre-surgical assessment, surgical course and post-operational parameters in women wishing to preserve their uterus and fertility who underwent myomectomy by minilaparotomy in the Department of Gynecology and Gynecological Oncology at the Polish Mother's Memorial Hospital – Research Institute in Lodz in the years 2008–2014. Material and methods A total of 76 patients were qualified for minilaparotomy due to a benign gynecological pathology. Only 21 patients with uterine fibroids who wanted to preserve their uterus and fertility were appropriate for this study. Patients’ records were analyzed in terms of: epidemiological history, surgical course, postoperative stay and pathological data. All studied patients were asked in 2014 about conception and pregnancy after minilaparotomy. Results The median age was 35.7 years. The median patient body mass index (BMI) was 24 kg/m2. The average decrease of hemoglobin was 1.5 g/dl. The size of the myoma was between 1.5 and 15 cm. There were no serious post-surgical complications. The size of the myoma did not correlate significantly with operation time, BMI or blood loss. There was no statistically significant dependence between operation time and average hematocrit and hemoglobin decrease. In our group 7 patients who had undergone myomectomy tried to achieve conception. Four of them succeeded in pregnancy and gave birth to healthy infants. Conclusions Myomectomy performed via minilaparotomy is a safe procedure for patients willing to preserve their uterus and fertility, and it combines some advantages of both laparotomy and laparoscopy.

    Uterine fibroids (also known as leiomyomas or myomas) are common clonal neoplasms of the uterus. Fibroids have both smooth muscle and fibroblast components, in addition to a substantial amount of fibrous extracellular matrix, which all contribute to the pathogenetic process. Fibroids are extremely heterogeneous in their pathophysiology, size, location and clinical symptomatology. They are also a part of a range of disease in which some variants have facets of malignant behaviour but overall are benign. Risk for fibroids is associated with race; black women have a higher risk of developing fibroids earlier in life than their white counterparts and also develop more-severe forms of the disease. Clinically, fibroids account for one-third to half of all hysterectomies and are associated with substantial morbidity and health care costs for women of reproductive age. Indeed, current treatments are primarily surgical and interventional; approximately three-quarters of all fibroid treatments are hysterectomies. However, clinical innovations are emerging in the use of progesterone receptor modulators as a medical therapy. New information is rapidly accumulating about the genetic subgroups that lead to fibroid formation, which might aid further understanding of the clinical heterogeneity of this disease and lead to individualized treatments. This information is a crucial development given the current lack of high-quality evidence on which to base therapeutic decisions. PMID:27335259

    Four women with symptomatic uterine fibroids were treated by uterine artery embolization (UAE). In all cases both uterine arteries were embolized via a single femoral puncture with polyvinyl alcohol using a selective catheter technique. In three cases, the ovarian artery was not visible on the initial angiogram before embolization, but appeared after the second uterine artery had been treated. In one case of clinical failure following UAE, a repeat angiogram demonstrated filling of the fibroids from the ovarian artery. Anastomoses between uterine and ovarian arteries may cause problems for radiologists performing UAE and are a potential cause of treatment failure.

    Laparoscopic lavage and drainage is a novel approach for managing patients with Hinchey III diverticulitis. However, this less invasive technique has important limitations, which are highlighted in this systematic review. We performed a PubMed search and identified 6 individual series reporting the results of this procedure. An analysis was performed regarding treatment-related morbidity, success rates, and subsequent elective sigmoid resection. Data was available for 287 patients only, of which 213 (74%) were actually presenting with Hinchey III diverticulitis. Reported success rate in this group was 94%, with 3% mortality. Causes of failure were: (1) ongoing sepsis; (2) fecal fistula formation; and (3) perforated sigmoid cancer. Although few patients developed recurrent diverticulitis in follow-up, 106 patients (37%) eventually underwent elective sigmoid resection. Our data indicate that laparoscopic lavage and drainage may benefit a highly selected group of Hinchey III patients. It is unclear whether laparoscopic lavage and drainage should be considered a curative procedure or just a damage control operation. Failure to identify patients with either: (1) feculent peritonitis (Hinchey IV); (2) persistent perforation; or (3) perforated sigmoid cancer, are causes of concern, and will limit the application of this technique.

MC Indoe vaginoplasty is universally acceptable and widely practiced procedure for neocolposis reconstruction. Simultaneous reconstruction of vagina with simultaneous continued uterine drainage presents surgical challenge. We offer a simple solution of creating a vaginal mould using a 10 ml disposable syringe, which enables graft application of neovaginal cavity with simultaneous protected uterine drainage per vaginum. Total 10 patients were included in this study of which 4 needed uterine drainage procedure in addition to neovaginal creation. All the patients fared well, there were no problems regarding graft loss or vaginal mould extrusion etc. Fabrication of mould for graft enables easy dressing changes with out disturbing the skin graft. This innovation offers a simple easily reproducible and cheap way of fabricating vaginal mould for McIndoe vaginoplasty. It is especially useful for neovaginal graft application and simultaneous uterine drainage. PMID:27274126

    New abdominal and vaginal hysterectomy techniques, such as classic intrafascial serrated edged macro-morcellator (SEMM) hysterectomy (CISH), by pelviscopy/laparoscopy or laparotomy, and intrafascial vaginal hysterectomy (IVH), are both essentially supravaginal techniques. It has been claimed that they give a prophylaxis against cervical stump carcinoma by coring out the cervix with the SEMM. We set out to answer two questions: 1) How can vaginosonography help to choose an adequate SEMM diameter so that the cervical mucosa and transformation zone are completely removed, and 2) How often do cervical glands remain after the coring out procedure? We were able to show a good correlation between sonographic and histological morphology by giant and serial sections. In 253 CISH operations, resection of both endocervix and transformation zone was complete in 92.9%. Dysplasias were always removed completely; only 18 cervical cores exhibited healthy glands (retention cysts) in the resection margin. Therefore, CISH procedures should be able to prevent most of the cervical stump carcinomata that follow traditional supravaginal hysterectomy, but only long-term follow-up will give the final proof.

    Uterine fibroids (leiomyomas) are benign smooth muscle tumors of the uterus. Fibroids can develop anywhere within the muscular wall. Leiomyomas may be associated with infertility. Laparoscopic myomectomy is often used to remove symptomatic intramural or subserosal fibroids. Advantages of the procedure include short recovery time and minimal perioperative morbidity. At the same time, the multilayer suture technique is more complicated during laparoscopy. A rare but serious complication of laparoscopic myomectomies is uterine rupture. A brief review of the literature and a clinical example of a 33-year-old woman with history of infertility, laparoscopic myomectomies and uterine rupture followed by peripartum hemorrhage is presented. The treatment of leiomyomas is a challenge not only because of possible recurrence but also due to long-term consequences following successful myomectomy. Management of patients with uterine scars should include careful planning of the route of delivery, as the risk of rupture may be increased. PMID:26976991

    The most probable reason for persistent postbreeding endometritis in mares is weak myometrial contractility. The influence of oxytocin (OT; an ecbolic agent) and flunixin meglumine (FLU; a prostaglandin inhibitor serving as a model for mares with decreased uterine contractility) on uterine response to artificial insemination (AI) was studied in mares with no history of reproductive failure. The mares were treated intravenously with 10 mL saline (Group C, n=10) or 0.01 IU/kg OT (Group OT, n=10) 2, 4, 8, and 25 h after AI. Group FLU (n=11) was treated with 1.1mg/kg FLU 2h after AI and with saline thereafter. The mares received the same treatments in the first and third cycles but were sampled either at 8 or 25 h. The amount of intrauterine fluid (IUF) and edema and the number of uterine contractions were recorded before AI and 10 min after the treatments using transrectal ultrasonography. At 8h after AI, the mares were treated with human chorionic gonadotropin, and, after 8-h or 25-h scans, a 500-mL uterine lavage and a biopsy were performed. Ovulation was confirmed at 48 h and pregnancy 14 to 17 d after AI. No manipulations were done during the second estrus. At 8h after AI, Group FLU had more polymorphonuclear leukocytes (PMNs) in the uterine lavage fluid than did Group OT (P<0.05), but uterine contractions did not differ significantly. At 25 h, the PMN concentrations were low in all groups. Group OT rarely showed IUF. The uterine biopsy specimens of Group FLU showed less inflammation of the stroma but more PMNs in the uterine lumen 8h after AI than that of the control group (P<0.05). The pregnancy rates did not differ between the groups (63% C, 53% OT, and 50% FLU). Oxytocin rapidly and effectively removed IUF and PMNs after AI and thereby shortened the duration of postbreeding inflammation. PMID:19783032

    Uterine leiomyomata are the direct cause of a significant health-care burden for women, their families, and society as a whole. Because of the long experience with the mode of treatment, surgical myomectomy remains the gold standard for treating reproductive-age women; however, in the recent years, the wide evolution of less invasive approaches led to a change in the options used by the clinician to treat symptomatic fibroids. Minimally invasive procedures such as uterine artery embolization (UAE) are increasingly used to treat symptomatic fibroids. Other alternative treatments are becoming more diffuse, such as magnetic resonance-guided high-frequency focused ultrasound surgery (MRgFUS), cryomyolysis, vaginal occlusion, and laparoscopic closure of the uterine arteries. Both advantages and limitations of these techniques under development must be taken into account, but this wider range of choices is being increasingly considered for a tailored treatment. This article aims to enable health-care providers with the tools to provide the latest evidence-based care in the minimally invasive or noninvasive management of this common problem. PMID:26711881

    The uterine inversion is a rare and severe puerperal complication. Uncontrolled cord traction and uterine expression are the common causes described. We report a case of uterine inversion stage III caused by poor management of the third stage of labor. It was about a 20 years old primigravida referred in our unit for postpartum hemorrhage due to uterine atony. After manual reduction of the uterus, the use of intra uterine balloon tamponade helped to stop the hemorrhage. The uterine inversion is a rare complication that may cause maternel death. The diagnosis is clinical and its management must be immediate to avoid maternal complications. PMID:26977239

    Uterine cirsoid aneurysm is uncommon. It is important to make a diagnosis of this disease preoperatively, because repeated curettages may induce life-threatening massive genital bleeding. We present a case of a 51-year-old woman with uterine cirsoid aneurysm in whom MRI and MRA were very useful for the preoperative diagnosis. The radiologic appearances on ultrasonography, CT, conventional SE MRI, MRA, dynamic MRI, and pelvic angiography are presented. Conventional SE T1-weighted and T2-weighted images demonstrated multiple flow voids in the uterus and bilateral adnexal regions. MRA demonstrated a cluster of distinct, tortuous, and coiled vascular channels in the pelvis. MRA could obtain images almost equal to angiography and was considered to be an excellent noninvasive imaging technique for the diagnosis of uterine cirsoid aneurysm. 28 refs., 7 figs

    Minimally invasive surgery, specifically robotic surgery, became a common technique used by gynecological surgeons over the last decade. The realization of the first human uterine transplantation commenced new perspectives in the treatment of uterine agenesia or infertility in women with history of hysterectomy at a young age. Robot-assisted technique may enhance the safety of the procedure by facilitating the microvascular anastomosis, vaginal anastomosis, and ligaments’ fixation. This study proposes the formation of a multicenter collaboration group to organize a protocol with the aim to clarify the possible role of robotic surgery in uterine transplantation. PMID:26401113

    Lipomatous tumors of the uterus are unusual, benign neoplasms seen in postmenopausal women. Although many of the mixed-type cases such as lipoleiomyoma and fibrolipoma have been reported, pure uterine lipomas are extremely rare. In the literature, a few cases with pure uterine lipoma have been reported. We first present the advanced magnetic resonance findings of pure uterine lipoma, followed by those of ultrasonography (US) and computed tomography (CT). We markedly detected lipid peaks on the magnetic resonance spectroscopy (MRS) and the apparent diffusion coefficient value to be 0.00 due to chemical-shift effects with diffusion-weighted imaging (DWI). Although pelvic lipomatous tumors can be diagnosed with US and CT, in some cases, further workup may be required to localize the lesion. MRI may yield more valuable data for differential diagnosis. MRS and DWI findings provide additional clues on the nature of the lesion. PMID:17905250

    Vascular lesions of the uterus are rare; most reported in the literature are arteriovenous malformations (AVMs). Uterine AVMs can be congenital or acquired. In recent years, there has been an increasing number of reports of acquired vascular lesions of the uterus following pregnancy, abortion, cesarean delivery, and curettage. It can be seen from these reports that there is confusion concerning the terminology of uterine vascular lesions. There is also a lack of diagnostic criteria and management guidelines, which has led to an increased number of unnecessary invasive procedures (eg, angiography, uterine artery embolization, hysterectomy for abnormal vaginal bleeding). This article familiarizes readers with various vascular lesions of the uterus and their management. PMID:24340126

    Symptomatic fibroids are a common indication for hysterectomy or myomectomy. Although rare, unexpected gynecologic malignancies in presumed fibroids have been documented. In cases where tissue retrieval is performed through morcellation, there is increasing concern that intra-abdominal dispersion of occult uterine malignancies may lead to peritoneal dissemination and worse outcomes. We examined the available literature to determine the prevalence of all uterine cancers in women undergoing hysterectomy or myomectomy for benign uterine disease, with attention to the risk of morcellating occult uterine sarcomas. We also reviewed the available tools for preoperative discrimination between benign and malignant uterine disease. PMID:26645385

    We provide a review of proteomic techniques used to characterize the bronchoalveolar lavage fluid (BALF) proteome of normal healthy subjects. Bronchoalveolar lavage (BAL) is the most common technique for sampling the components of the alveolar space. The proteomic techniques used to study normal BALF include protein separation by 2D gel electrophoresis whereby proteins were identified by comparison to a reference gel as well as high pressure liquid chromatography (HPLC)-tandem mass spectrometry technique, also known as shotgun proteomics. We summarize recent progress using shotgun MS technologies to define the normal BALF proteome. Surprisingly, we find that despite advances in shotgun proteomic technologies over the course of the last ten years, which have resulted in greater numbers of proteins being identified, the functional landscape of normal BALF proteome was similarly described by all methods examined.

    Dysfunctional uterine bleeding is most commonly associated with chronic anovulation. Early diagnosis of anovulation is important; the induction of regular withdrawal periods using a progestin such as Provera prevents the development of endometrial hyperplasia with the subsequent inevitable occurrence of a heavy, frightening vaginal bleed. The etiology of dysfunctional uterine bleeding occurring during ovulatory cycles is unknown and all medical therapies at present are necessarily experimental. Hysterectomy is probably the treatment of choice for women who have finished their childbearing career and in whom persisting menorrhagia during ovulatory cycles results in anemia. PMID:21283453

    Ranging from aplastic uterus (including Mayer-Rokitansky-Kuster-Hauser syndrome) to incomplete septate uterus, uterine malformations as a group are relatively frequent in the general population. Specific causes remain largely unknown. Although most occurrences ostensibly seem sporadic, familial recurrences have been observed, which strongly implicate genetic factors. Through the study of animal models, human syndromes, and structural chromosomal variation, several candidate genes have been proposed and subsequently tested with targeted methods in series of individuals with isolated, non-isolated, or syndromic uterine malformations. To date, a few genes have garnered strong evidence of causality, mainly in syndromic presentations (HNF1B, WNT4, WNT7A, HOXA13). Sequencing of candidate genes in series of individuals with isolated uterine abnormalities has been able to suggest an association for several genes, but confirmation of a strong causative effect is still lacking for the majority of them. We review the current state of knowledge about the developmental origins of uterine malformations, with a focus on the genetic variants that have been implicated or associated with these conditions in humans, and we discuss potential reasons for the high rate of negative results. The evidence for various environmental and epigenetic factors is also reviewed. © 2016 Wiley Periodicals, Inc. PMID:27273803

    Bronchoalveolar lavage is an invaluable means of accurately evaluating the inflammatory and immune processes of the human lung. Although lavage recovers only those cells and proteins present on the epithelial surface of the lower respiratory tract, comparison with open lung biopsies shows that these constituents are representative of the inflammatory and immune systems of the alveolar structures. With the use of these techniques, sufficient materials are obtained from normal individuals to allow characterization of not only the types of cells and proteins present but their functions as well. Such observations have been useful in defining the inflammatory and immune capabilities of the normal lung and provide a basis for the study of lung disease. Lavage methods have been used to characterize inflammatory and immune processes of the lower respiratory tract in destructive, infectious, neoplastic, and interstitial disorders. From the data already acquired, it is apparent that bronchoalveolar lavage will yield major insights into the pathogenesis, staging, and therapy decisions involved in these disorders.

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    The investigators present a novel image-guided embolization, not previously described, of a uterine arteriovenous malformation (AVM) resistant to endovascular management. The uterus was exposed surgically, and Histoacryl (Braun, Fulda, Germany) was injected directly into the nidus using ultrasound guidance and fluoroscopy. The patient had a successful full-term pregnancy after this procedure. This technique may be a useful alternative management strategy in patients with uterine AVM who fail traditional endovascular embolization and who still desire fertility.

    Postpartum hemorrhage (PPH) is a life-threatening complication of delivery. It is the leading cause of maternal mortality. During the last 15 years, several total uterine compressive sutures were described in literature. They have proven their effectiveness and safety in the management of severe PPH as an alternative to hysterectomy. We present in this paper a new technique of uterine compressive sutures based on removable uterine brace compressive sutures with compression of the uterus against the pubis. This technique may be more effective by using two mechanisms of uterine bleeding control and also may prevent uterine synechia by respecting the uterine cavity and the removal of the suture 1 or 2 days later. We also present the results of a 15 patients’ series using this new suture. PMID:25593967

    Introduction: Leiomyomas are benign tumors composed of smooth muscle cells and varying amounts of fibrous connective tissue commonly encountered in women of reproductive age group. Leiomyomas need hormonal milieu for their growth and maintenance. Unopposed estrogenic stimulation manifests as leiomyomas undergoing secondary changes, endometrial proliferation or hyperplasia, and other associated pathological findings. Objective: To study and analyze various histopathological changes within uterine leiomyomas in hysterectomy specimens. And also, to analyze the associated endometrial and adnexal structures pathology. Materials and Methods: A 4 years retrospective study from June 2010 to June 2014 conducted in the Department of Pathology and Obstetrics and Gynecology, ESIC Medical College and PGIMSR, wherein 820 hysterectomy specimens clinically diagnosed as uterine leiomyomas were subjected to histopathological examination and relevant clinical data were analyzed. Results: Leiomyomas occurred mostly in women aged 31-50 years (90.23%). Menorrhagia (49.36%) and pain abdomen (30.6%) were the chief clinical manifestations. Endometrial patterns commonly seen were proliferative and hyperplastic endometrium together accounting for 73.4% and dual pathology with adenomyosis was 29.1%. Four cases of tubercular etiology and a single case of granulosa cell tumor of ovary was noted. Conclusion: Though hysterectomy is a routine procedure in the management of uterine leiomyomas, occasional cases of tumor or infective pathology may be missed. Therefore, histopathology is mandatory and conscientious quest must be done for confirmed diagnosis and ensuring optimal management. PMID:27134477

    Cyclic or irregular uterine bleeding is common in perimenarchal and perimenopausal women with or without endometrial hyperplasia. The disturbance often requires surgical treatment because of its negative effects on both blood loss and abnormal endometrial growth including the development of endometrial cancer. The endometrium is often overstimulated during the perimenopausal period when estrogen/progesterone production is unbalanced. A therapeutical approach with gonadotropin-releasing hormone agonist (GnRHa) was proposed in a depot formulation (Zoladex) that induces a sustained and reversible ovarian suppression. To avoid the risk of osteoporosis and to obtain adequate endometrial proliferation and differentiation during ovarian suppression, transdermal 17-beta-estradiol and oral progestin were administered. Results of 20 cases versus 20 controls showed a reduction of metrorrhagia, a normalization of hemoglobin plasma concentration, and an adequate proliferation and secretory differentiation of the endometrium of patients with abnormal endometrial growth. Abnormal uterine bleeding is mainly due to uterine fibrosis and an inadequate estrogen and/or progesterone production or to a disordered estrogen transport from blood into the endometrium. In premenopausal women, endometrial hyperplasia may be part of a continuum that is ultimately manifested in the histological and biological pattern of endometrial carcinoma. The regression of endometrial hyperplasia obtained by using the therapeutic regimen mentioned above represents a preventive measure for endometrial cancer. Finally the normalization of blood loss offers a good medical alternative to surgery for patients with DUB. PMID:7978956

    Aim: To investigate the expression of calcium channel protein in uterine fibroids, and to explore the relationship between calcium signaling pathway and the pathogenesis of uterine fibroids. Methods: Uterine fibroid tissues (UFC) and adjacent healthy uterine smooth muscle tissues (SMC) were collected from 30 cases of uterine fibroids. Real-time quantitative PCR and western blot were used to detect cell membrane calcium channel protein subtypes: TRPC1, TRPC3, TRPC4, TRPC6, TRPM6 and TRPM7. The effects of genes exhibiting most-notable differences on cell proliferation were examined using gene interference techniques. Results: We found that calcium channel protein subtypes expressed differently in fibroids and the surrounding smooth muscles. The mRNA and protein expressions of TRPC1 and TRPM7 were higher in uterine fibroid tissues than in smooth muscle (P < 0.05), while no obvious difference was found in terms of other subtypes (TRPC3, TRPC4, TRPC6 and TRPM6). In cultured uterine leiomyoma cells, modifying the expressions of TRPC1 and TRPM7 significantly affected the proliferation rate of uterine fibroids. Conclusion: Calcium channel subtypes TRPC1 and TRPM7 exhibit different expression patterns in uterine fibroids and surrounding smooth muscles, suggesting that calcium signaling pathway regulated by these calcium channel proteins may be associated with the incidence of uterine fibroids.

    We compared the ability to extract all stomach contents by using stomach tubes or gastric lavage to sample diets from blue catfish Ictalurus furcatus and flathead catfish Pylodictus olivarus. Pulsed gastric lavage (PGL) removed a significantly greater proportion of stomach content mass (95.6%) from blue catfish than did stomach tubes (14.6%). Percent mass of flathead catfish contents removed with PGL (96.0%) was not significantly different from that removed with stomach tubes (86.9%). Based on the greater effectiveness of PGL for blue catfish, combined with a shorter mean time required per sample (69 versus 118 s) and the better preservation of extracted diet material, we recommend using PGL as a nonlethal technique to collect diet samples from large catfishes.

    Broncho-alveolar lavage is a simple investigation to carry out and enables the gathering of biological information such as inflammatory and immuno-competent cells, tumour cells, microorganisms as well as mineral particles which are found in the biological milieux present in the distal air spaces. The performance of LBA assumes a mastering of the correct technical aspects of this method of investigation, particularly in the phase of injecting and recovering of physiological saline and an understanding of the indications and contraindications of the technique. The interpretation of the information gathered by cytological, microbiological, mineralogical and biochemical study of the bronchoalveolar lavage liquid should comply with a strict set of rules and justifies a close working contact between the clinician and the biological scientist.

    The analysis of airway fluid, as sampled by bronchoalveolar lavage (BAL), provides a minimally invasive route to interrogate lung biology in health and disease. Here, we used immunodepletion, coupled with gel- and label-free LC-MS/MS, for quantitation of the BAL fluid (BALF) proteome in samples recovered from human subjects following bronchoscopic instillation of saline, lipopolysaccharide (LPS) or house dust mite antigen into three distinct lung subsegments. Among more than 200 unique proteins quantified across nine samples, neutrophil granule-derived and acute phase proteins were most highly enriched in the LPS-exposed lobes. Of these, peptidoglycan response protein 1 was validated and confirmed as a novel marker of neutrophilic inflammation. Compared to a prior transcriptomic analysis of airway cells in this same cohort, the BALF proteome revealed a novel set of response factors. Independent of exposure, the enrichment of tracheal-expressed proteins in right lower lung lobes suggests a potential for constitutive intralobar variability in the BALF proteome; sampling of multiple lung subsegments also appears to aid in the identification of protein signatures that differentiate individuals at baseline. Collectively, this proof-of-concept study validates a robust workflow for BALF proteomics and demonstrates the complementary nature of proteomic and genomic techniques for investigating airway (patho)physiology.

    During the luteal phase and the early months of pregnancy, there is a dense mucosal infiltration of CD56+ natural killer (NK) cells. These uterine NK cells have a phenotype (CD56bright, CD16-, mCD3-) which distinguishes them from peripheral blood NK cells (CD56dim, CD16bright, mCD3-). The uterine NK cells are in close association with extravillous trophoblast (EVT) cells which infiltrate into the decidua and maternal spiral arteries. This subpopulation of trophoblast expresses two human leukocyte antigen (HLA) class I molecules, HLA-G and HLA-C. Circulating NK cells express receptors for HLA class I molecules. We have recently found evidence that similar receptors are present on decidual NK cells belonging to both the Killer Inhibitory Receptor (KIR) and CD94 families. The repertoire of NK receptors expressed varies between different women. The findings indicate that decidual NK cells do have receptors for trophoblast HLA class I molecules. Experiments are underway to determine the effects of this interaction on NK cell function. PMID:10027599

    A guarded, sterile swab is used to obtain samples for uterine culture. With the mare in stocks, the tail bandage and the perineum washed, the culture rod is introduced into the vagina with a gloved hand. After the rod is guided through the cervix, the guard cap is dislodged and the swab is rubbed along the endometrium, after which the rod is extracted. Samples for uterine culture should only be obtained during full estrus. Swabs should be directly plated onto agar within 2 hours of collection. Blood agar is appropriate for initial screening, but use of specialized types of agar expedites identification of microbes. Plates are incubated at 37 C and inspected for growth every 12 hours. The type and number of bacterial colonies should be coupled with the history and clinical signs in deciding on the necessity and type of treatment. Pure, heavy bacterial growth is usually accompanied by clinical signs of infection. Interpretation of the significance of moderate bacterial growth may be aided by cytologic examination of endometrial smears, made by rolling the swab onto a glass slide and staining with Diff - Quik . Large numbers of neutrophils indicate the need for antibiotic therapy. Mixed bacterial growth and variable numbers of neutrophils usually indicate faulty sampling technic. Microaerophilic or anaerobic cultures may aid diagnosis in cases of equivocal aerobic culture results. PMID:6377040

    Adenocarcinoma of the endometrium (also known as endometrial cancer or more broadly as uterine cancer or carcinoma of the uterine corpus) is the most common malignancy of the female genital tract in the United States. An estimated 49,560 new uterine cancer cases will occur in 2013, with 8190 deaths resulting from the disease. Uterine sarcomas (stromal/mesenchymal tumors) are uncommon malignancies, accounting for approximately 3% of all uterine cancers. The NCCN Guidelines for Uterine Neoplasms describe malignant epithelial carcinomas and uterine sarcomas; each of these major categories contains specific histologic groups that require different management. This excerpt of these guidelines focuses on early-stage disease. PMID:24586086

    Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should also be considered. In this work, we have developed a group of parametric models to simulate uterine contractions during labor and delivery. Through analysis of real patient records, we propose to model uterine contraction signals by three major components: regular contractions, impulsive noise caused by fetal movements, and low amplitude noise invoked by maternal breathing and measuring apparatus. The regular contractions are modeled by an asymmetric generalized Gaussian function and least squares estimation is used to compute the parameter values of the asymmetric generalized Gaussian function based on uterine contractions of real patients. Regular contractions are detected based on thresholding and derivative analysis of uterine contractions. Impulsive noise caused by fetal movements and low amplitude noise by maternal breathing and measuring apparatus are modeled by rational polynomial functions and Perlin noise, respectively. Experiment results show the synthesized uterine contractions can mimic the real uterine contractions realistically, demonstrating the effectiveness of the proposed algorithm.

    Structural patterning and functional programming of uterine tissues are mechanistically coupled. These processes ensure anteroposterior differentiation of uterine tissues from adjacent segments of the developing female reproductive tract (FRT) and radial patterning that establishes uterine-specific histoarchitecture and functionality. Uterine organogenesis begins prenatally and is completed postnatally. Genes required for FRT development include Pax2, Lim1 and Emx2, genes in the abdominal-B Hoxa cluster, and members of both Wnt and Hedgehog (Hh) gene families. Disruption of morphoregulatory gene expression patterns can prevent FRT development entirely or compromise uterine organogenesis specifically. Oestrogen receptor-alpha (ER) -dependent events associated with development of the neonatal porcine uterus can be altered by administration of oestrogen (E) or relaxin (RLX). Expression of the RLX receptor is detectable in porcine endometrium at birth, before onset of ER expression and uterine gland genesis. Uterotrophic effects of both E and RLX can be inhibited with the ER antagonist ICl 182,780, indicating that RLX may act via crosstalk with the ER system in neonatal tissues. Exposure of neonatal gilts to E alters temporospatial patterns of Hh, Wnt and Hoxa expression in the uterine wall. Oestrogen given for two weeks from birth produced hypoplastic adult porcine uteri that were less responsive to periattachment conceptus signals as reflected by reduced growth response and luminal fluid protein accumulation, altered endometrial gene expression, and reduced capacity for conceptus support. Data reinforce the concept that factors affecting signalling events in uterine tissues that produce changes in morphoregulatory gene expression patterns during critical organisational periods can alter the developmental trajectory of the uterus with lasting consequences. Thus, uterine tissues can be programmed epigenetically for success or failure during perinatal life. PMID

    The purpose of this study was to determine if hydrodebridement with pulsed lavage facilitates the removal of necrotic tissue, promotes healing, and increases comfort in the homebound patient. Home healthcare provides cost-effective care in the setting that is most conducive to healing. People want to be at home, yet many illnesses require services that cannot be obtained at home. Wound care sometimes falls into this category. Pulsed lavage has expanded treatment options for the homebound patient. Hydrodebridement with pulsed lavage is site specific, avoids cross contamination, and is less expensive than whirlpool therapy. It also may facilitate the removal of necrotic tissue and promote the formation of healthy granulation tissue. The authors performed a retrospective audit to gather data on 28 patients who received pulsed lavage treatments at home. A descriptive analysis of five variables that affect healing was undertaken including mobility/activity, nutritional status, cardiovascular/respiratory status, continence, and sensory perception. All of the clients in the sample achieved a clean, warm, moist wound bed, free of signs and symptoms of infection, absence of necrotic tissue, and the presence of granulation tissue to meet the definition of "ready for healing" as presented in the literature. The majority of clients experienced no pain. Although comorbid conditions required rehospitalization for 35.7% of the sample, the conditions did not interfere with healing. Hydrodebridement with pulsed lavage is a viable nontraumatic, noninvasive, site-specific treatment alternative for patients receiving care in the home. PMID:10788926

    A 65-y-old Japanese man was referred to the respiratory medicine department because of abnormal radiologic findings. High-resolution chest computed tomography scans revealed a geographic distribution of ground-glass opacities and associated thickening of the interlobular septa (crazy-paving patterns) in both lower lobes. He had a habit of drinking 400-500 mL of milk and 400-800 mL of canned coffee with milk every day. A swallowing function test revealed liquid dysphagia. Bronchoalveolar lavage fluid cytology findings showed multiple lipid-laden macrophages. Taken together, these findings revealed exogenous lipoid pneumonia. We performed bronchoscopic segmental lavage therapy 3 times in the left lung. After the treatment, the radiologic findings improved in both lungs. The patient has not experienced a recurrence of lipoid pneumonia in 2 y to date. In conclusion, a case of exogenous lipoid pneumonia was successfully treated with bronchoscopic segmental lavage therapy. PMID:25161297

    Uterine adenosarcomas (UAs) are biphasic lesions composed of a malignant mesenchymal (ie stromal) component and an epithelial component. UAs are generally low-grade and have a favourable prognosis, but may display sarcomatous overgrowth (SO), which is associated with a worse outcome. We hypothesized that, akin to breast fibroepithelial lesions, UAs are mesenchymal neoplasms in which clonal somatic genetic alterations are restricted to the mesenchymal component. To characterize the somatic genetic alterations in UAs and to test this hypothesis, we subjected 20 UAs to a combination of whole-exome (n = 6), targeted capture (n = 13) massively parallel sequencing (MPS) and/or RNA sequencing (n = 6). Only three genes, FGFR2, KMT2C and DICER1, were recurrently mutated, all in 2/19 cases; however, 26% (5/19) and 21% (4/19) of UAs harboured MDM2/CDK4/HMGA2 and TERT gene amplification, respectively, and two cases harboured fusion genes involving NCOA family members. Using a combination of laser-capture microdissection and in situ techniques, we demonstrated that the somatic genetic alterations detected by MPS were restricted to the mesenchymal component. Furthermore, mitochondrial DNA sequencing of microdissected samples revealed that epithelial and mesenchymal components of UAs were clonally unrelated. In conclusion, here we provide evidence that UAs are genetically heterogeneous lesions and mesenchymal neoplasms. PMID:26592504

    Acute silicoproteinosis is a rare disease that occurs following a heavy inhalational exposure to silica dusts. Clinically, it resembles pulmonary alveolar proteinosis (PAP); silica exposure is thought to be a cause of secondary PAP. We describe a patient with biopsy-confirmed acute silicoproteinosis whose course was complicated by acute hypoxemic respiratory failure requiring mechanical ventilation. Without clinical improvement despite antibiotic and steroid treatment, the patient was scheduled for whole-lung lavage under general anesthesia. Anesthetic challenges included double-lumen tube placement and single-lung ventilation in a hypoxic patient, facilitating lung lavage, and protecting the contralateral lung from catastrophic spillage.

    This study comprised 30 patients who had not been exposed occupationally to dusts, but for whom a diagnosis of suspected pulmonary carcinoma had been made. Bronchoalveolar lavage fluids from these patients were analyzed by transmission electron microscopy and by energy-dispersive x-ray microanalysis in an effort to study the mineral particulate present in the alveolar region. Particles of silica, silicates, oxides, sulphates, and metal alloys were detected in various percentages in each subject. The smoking habits of two groups of patients that were defined by their bronchoalveolar lavage particulate concentrations (i.e., lower or higher than the median of the distribution) differed significantly.

    Postpartum uterine diseases of dairy cows compromise animal welfare and may result in early removal from the herd or impaired reproductive performance. The relationship between poor immune status around calving and uterine diseases is well established; however, that between natural antibodies (NAb) and uterine health has not yet been studied. The objective of this study was to evaluate the association of circulating NAb levels around parturition with puerperal metritis, clinical endometritis, and the intrauterine presence of the Escherichia coli virulence factor FimH. One hundred six pregnant heifers were enrolled; NAb in serum samples collected at 30 ± 3 d prepartum and at 2 ± 1 and 35 ± 3 d in milk (DIM) were measured by ELISA. Puerperal metritis was defined as the presence of fetid, watery, red-brown uterine discharge and rectal temperature >39.5°C at 6 ± 1 DIM. Clinical endometritis was defined as presence of pus in the uterine lavage sample collected at 35 ± 3 DIM. The intrauterine presence of the fimH gene at 2 ± 1 DIM was evaluated by PCR. The overall optical density (wavelength of 650 nm) of ELISA-detected serum NAb was lower for cows diagnosed with puerperal metritis than for cows that did not have puerperal metritis. Additionally, cows diagnosed with clinical endometritis tended to have lower levels of NAb than did cows without clinical endometritis. Finally, FimH-positive cows had lower overall levels of serum NAb compared with FimH-negative cows. In conclusion, NAb detected in serum around parturition was associated with uterine health of dairy cows. PMID:25262191

    We report a new technique of brachytherapy consisting of intracavitary combined with computed tomography (CT)-guided interstitial brachytherapy for locally advanced cervical cancer. A Fletcher-Suit applicator and trocar point needles were used for performing high-dose rate brachytherapy under in-room CT guidance. First, a tandem and ovoids were implanted into the patient's vagina and uterus by conventional brachytherapy method. Based on clinical examination and MRI/CT imaging, operating radiation oncologists decided the positions of insertion in the tumor and the depth of the needles from the upper surface of the ovoid. Insertion of the needle applicator was performed from the vaginal vault inside the ovoid within the tumor under CT guidance. In treatment planning, dwell positions and time adaptations within the tandem and ovoids were performed first for optimization based on the Manchester system, and then stepwise addition of dwell positions within the needle was continued. Finally, dwell positions and dwell weights were manually modified until dose-volume constraints were optimally matched. In our pilot case, the dose of D90 to high-risk clinical target volume was improved from 3.5 Gy to 6.1 Gy by using our hybrid method on the dose-volume histogram. D1cc of the rectum, bladder and sigmoid colon by our hybrid method was 4.8 Gy, 6.4 Gy and 3.5 Gy, respectively. This method consists of advanced image-guided brachytherapy that can be performed safely and accurately. This approach has the potential of increasing target coverage, treated volume, and total dose without increasing the dose to organs at risk. PMID:21293072

    The appropriate surgical technique to treat patients with uterine fibroids is still a matter of debate as is the potential risk of incorrect treatment if histological examination detects a uterine sarcoma instead of uterine fibroids. The published epidemiology for uterine sarcoma is set against the incidence of accidental findings during surgery for uterine fibroids. International comments on this topic are discussed and are incorporated into the assessment by the German Society for Gynecology and Obstetrics (DGGG). The ICD-O-3 version of 2003 was used for the anatomical and topographical coding of uterine sarcomas, and the “Operations- und Prozedurenschlüssel” (OPS) 2014, the German standard for process codes and interventions, was used to determine surgical extirpation methods. Categorical qualifiers were defined to analyze the data provided by the Robert Koch Institute (RKI), the German Federal Bureau of Statistics (DESTATIS; Hospital and Causes of Death Statistics), the population-based Cancer Register of Bavaria. A systematic search was done of the MEDLINE database and the Cochrane collaboration, covering the period from 1966 until November 2014. The incidence of uterine sarcoma and uterine fibroids in uterine surgery was compared to the literature and with the different registries. The incidence of uterine sarcoma in 2010, standardized for age, was 1.53 for Bavaria, or 1.30 for every 100 000 women, respectively, averaged for the years 2002–2011, and 1.30 for every 100 000 women in Germany. The mean incidence collated from various surveys was 2.02 for every 100 000 women (0.35–7.02; standard deviation 2.01). The numbers of inpatient surgical procedures such as myoma enucleation, morcellation, hysterectomy or cervical stump removal to treat the indication “uterine myoma” have steadily declined in Germany across all age groups (an absolute decrease of 17 % in 2012 compared to 2007). There has been a shift in the preferred method of surgical

This review will focus on the key articles representing the best evidence to summarize the outcomes from uterine embolization. This review will attempt to answer three important questions associated with uterine embolization. First, does uterine embolization relieve symptoms caused by uterine fibroids? Second, how well does the improvement in symptoms and quality of life after uterine embolization compare with standard surgical options for fibroids? Finally, how durable is the improvement in fibroid-related symptoms and quality of life after embolization? PMID:24436560

Methods Fifty-two subjects (26 uRM and 26 control women) underwent 2D Doppler measurement of pulsatility index and resistance index of the uterine arteries in both the follicular and midluteal phase of the cycle. Additionally, 3D ultrasonography determination of vascularisation index, flow index, and vascularisation flow index was carried out with the aid of the VOCAL technique. Serum assay for the presence of ANA was performed in all women. Results Pulsatility index of ANA+ uRM women was higher than that of ANA- uRM women and control ANA+ and ANAwomen, both in the follicular and in the midluteal phase of the cycle. Vascularisation index in ANA- uRM women was significantly higher than that in ANA+ control women. Flow index in uRM ANA+ women was significantly lower than that of each of the other groups. Conclusion ANA might be involved in uRM by determining an impairment in uterine blood flow hemodynamic, particularly in uterine blood flow intensity and uterine artery impedance. PMID:26623408

    Objective To develop an orthotopic, allogeneic, uterine transplantation technique and an effective immunosuppressive protocol in the sheep model. Methods In this pilot study, 10 sexually mature ewes were subjected to laparotomy and total abdominal hysterectomy with oophorectomy to procure uterus allografts. The cold ischemic time was 60 min. End-to-end vascular anastomosis was performed using continuous, non-interlocking sutures. Complete tissue reperfusion was achieved in all animals within 30 s after the vascular re-anastomosis, without any evidence of arterial or venous thrombosis. The immunosuppressive protocol consisted of tacrolimus, mycophenolate mofetil and methylprednisolone tablets. Graft viability was assessed by transrectal ultrasonography and second-look laparotomy at 2 and 4 weeks, respectively. Results Viable uterine tissue and vascular patency were observed on transrectal ultrasonography and second-look laparotomy. Histological analysis of the graft tissue (performed in one ewe) revealed normal tissue architecture with a very subtle inflammatory reaction but no edema or stasis. Conclusion We have developed a modified procedure that allowed us to successfully perform orthotopic, allogeneic, uterine transplantation in sheep, whose uterine and vascular anatomy (apart from the bicornuate uterus) is similar to the human anatomy, making the ovine model excellent for human uterine transplant research.

    Results of bronchoalveolar lavage (BAL), 67Ga scanning, and serum angiotensin-converting enzyme (SACE) assay are compared in the assessment of pulmonary involvement in ten cases of extrathoracic sarcoidosis. Standard clinical, radiologic, and pulmonary function tests detected no pulmonary changes in these patients, but BAL demonstrated an increased alveolar lymphocytosis in eight of ten cases. SACE levels were increased in two cases, and the thoracic gallium uptake was normal in all cases. BAL appears to be the best technique for diagnosing latent pulmonary involvement in extrathoracic sarcoidosis.

    The purpose of this study was to evaluate safety, efficacy or complications of uterine artery embolization (UAE). Patients with symptomatic uterine fibroids (n = 157) were treated by selective bilateral UAE using 350–500 μm sized polyvinyl alcohol particles. Bilateral UAE was successful in 152 (96.8%) cases. Baseline measures of clinical symptoms and MRI taken before the procedure were compared to those taken 3, 6, and 12 months after embolotherapy. Also, complications and outcomes were analyzed after procedure. All patients had an uneventful recovery and were able to return to normal activity within two weeks of embolization. After the procedure, most patients experienced crampy pelvic pain, of variable intensity, which was well managed with the standard analgesia protocol. Five (3%) of participants had persisting amenorrhea after procedure. None reported any new gynecologic or medical problem during the follow-up period. There were no deaths and no major permanent injuries. Reductions in mean uterine volume were 61% (P < 0.01) and in dominant fibroid volume 66% (P≤0.01). The follow-up showed significant improvement of bleeding. In conclusion, uterine artery embolization is a successful, minimal invasive treatment of uterine fibroids that preserves the uterus, had minimal complications, and requires short hospitalization and recovery.

    We sought to evaluate the clinical feasibility and mid- to long-term effects of laparoscopic uterine artery occlusion before myomectomy in the treatment of uterine myomas. A total of 566 patients with uterine myoma were treated by laparoscopic uterine artery occlusion before myomectomy from October 2001 through July 2007. Mean blood loss was 88.2 +/- 52.7 mL (95% CI 82.7-93.8). The highest postoperative temperature was 37.8 +/- 0.3 degrees C, and the postoperative morbidity was 5.7% (32/566). Number of days to the return of bowel movement was 1.9 +/- 0.5d and in hospital stay after surgery was 7.7 +/- 2.5d. Complications included 2 instances of subcutaneous emphysema, 1 of vaginal bleeding, and 3 of mild intestinal obstruction. At a median of 26.3 months (range 6-69 months) of follow-up, the rate of myoma recurrence was 3.0% (15/517), uterus volume reduction was 48.9%, and correction of menstruation abnormality was 97.1% (502/517). Laparoscopic uterine artery occlusion before myomectomy can expand myomectomy indications with better results. PMID:18439509

    Abnormal uterine bleeding (AUB) is a common and debilitating condition with high direct and indirect costs. AUB frequently co-exists with fibroids, but the relationship between the two remains incompletely understood and in many women the identification of fibroids may be incidental to a menstrual bleeding complaint. A structured approach for establishing the cause using the Fédération International de Gynécologie et d'Obstétrique (FIGO) PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy (and hyperplasia), Coagulopathy, Ovulatory disorders, Endometrial, Iatrogenic and Not otherwise classified) classification system will facilitate accurate diagnosis and inform treatment options. Office hysteroscopy and increasing sophisticated imaging will assist provision of robust evidence for the underlying cause. Increased availability of medical options has expanded the choice for women and many will no longer need to recourse to potentially complicated surgery. Treatment must remain individualised and encompass the impact of pressure symptoms, desire for retention of fertility and contraceptive needs, as well as address the management of AUB in order to achieve improved quality of life.

    2012-01-01

    Uterine leiomyomas (also called myomata or fibroids) are the most common gynecologic tumors in the United States. The prevalence of leiomyomas is at least 3 to 4 times higher among African American women than in white women. Pathologically, uterine leiomyomas are benign tumors that arise in any part of the uterus under the influence of local growth factors and sex hormones, such as estrogen and progesterone. These common tumors cause significant morbidity for women and they are considered to be the most common indication for hysterectomy in the world; they are also associated with a substantial economic impact on health care systems that amounts to approximately $2.2 billion/year in the United States alone. Uterine myomas cause several reproductive problems such as heavy or abnormal uterine bleeding, pelvic pressure, infertility, and several obstetrical complications including miscarriage and preterm labor. Surgery has traditionally been the gold standard for the treatment of uterine leiomyomas and has typically consisted of either hysterectomy or myomectomy. In recent years, a few clinical trials have evaluated the efficacy of orally administered medications for the management of leiomyoma-related symptoms. In the present review, we will discuss these promising medical treatments in further detail. PMID:22378865

    Male Hartly guinea pigs and Fischer rats 344 were exposed to diesel exhaust (DE) concentrations at 0, 250, and 1500 micrograms/m3 in short terms, as well as long term experiments up to one year. The effects of inhaled DE on these rodents were evaluated using bronchoalveolar lavage technique. Both the morphological and functional studies of free lung cells and the biochemical and immunologic studies of the supernatant lavage fluid provided the basis for a quantitative species comparison of the pulmonary responses of exposed guinea pigs and rats versus age matched controls. Following inhalation of 250 micrograms DE/m3, there were little or no significant changes in either species. In contrast, at higher DE concentration, leukocytic infiltration and elevation of specific proteins in lavage fluids were observed in both species. The findings occurred and persisted in both species. Some of the responses were species specific (e.g., the specific type of exudative leukocytes, appearance of reactive monocytes, and different amounts of free DE particles and debris in the lavage fluid). Other responses were similar in both species. Among them, the emergence and increase of lymphocytes was evidence of immunologic responses. Biochemical data from the supernatant fluid correlates with the changes in cellular population in the lavage. The responses appear to be dose and duration dependent. These data indicate that species differences occur. However, it is clear that the alveolar macrophage and granulocytic leukocytes continue to exert effective defense at the DE dose-durations studied. In general, rats appeared more resistant to DE exposure than guinea pigs.

    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. PMID:26851127

    Fibroids, which are benign smooth-muscle tumors of clonal origin, are the most common gynecologic tumors occurring in about 20 to 25 % of women over 30 years of age. The most frequent symptoms are pelvic pain and heavy menstrual bleeding resulting in anemia. The role of fibroids in infertility remains debated but probably mostly related to submucosal location due to implantation impairment. Although most women are asymptomatic (80%), fibroids can have a considerable impact on quality of life. Considering this impact and the cost associated with their management, treatment of fibroids is a public health concern. Treatment options for symptomatic fibroids include medical, surgical and alternatives techniques. Medical management is mainly based on the use of progestogens, antifibrinolytics agents, non-steroidal anti-inflammatory drugs, Gonadotropin-releasing hormone analogs selective progesterone receptor modulators. Surgical management includes myomectomy (hysteroscopic, laparoscopic, minilaparoscopic or laparotomic) and hysterectomy. The choice of surgery depends on several factors: the number, topography and size of myomas, the age of the patient and her desire for fertility, treatment history and her desire to keep the uterus. Alternatives techniques to surgery are mainly based on the uterine artery embolization. The aim of this article is to provide evidence based recommendations for the management of uterine fibroids.

    In recent years, there has been an increasing focus on the contributory role of uterine fibroids to infertility. The prevalence of these tumors increases with age, which becomes significant as more women are delaying childbearing. Therefore, fibroids and infertility frequently occur together. Treatment varies with fibroid location and size. The various methods of treatment include open myomectomy, laparoscopic or robot-assisted myomectomy, medical treatment, uterine artery embolization and magnetic resonance guided focused ultrasound surgery. While there is a general consensus on the treatment of submucosal fibroids, the management of intramural fibroids in the infertility patient remains controversial. This paper aims to review and summarize the current literature in regards to the approach to uterine fibroids in the infertile patient. PMID:25482490

    Uterine fibroids are the most common tumors in women and their prevalence is higher in patients with infertility. At present, they are classified according to their anatomical location, as no classification system includes additional parameters such as their size or number. There is a general agreement that submucosal fibroids negatively affect fertility, when compared to women without fibroids. Intramural fibroids above a certain size (>4 cm), even without cavity distortion, may also negatively influence fertility. However, the presence of subserosal myomas has little or no effect on fertility. Many possible theories have been proposed to explain how fibroids impair fertility: mechanisms involving alteration of local anatomical location, others involving functional changes of the myometrium and endometrium, and finally endocrine and paracrine molecular mechanisms. Nevertheless, any of the above mentioned mechanisms can cause reduced reproductive potential, thereby leading to impaired gamete transport, reduced ability for embryo implantation, and creation of a hostile environment. The published experience defines the best practice strategy, as not many large, well-designed, and properly powered studies are available. Myomectomy appears to have an effect in fertility improvement in certain cases. Excision of submucosal myomas seems to restore fertility with pregnancy rates after surgery similar to normal controls. Removal of intramural myomas affecting pregnancy outcome seems to be associated with higher pregnancy rates when compared to non-operated controls, although evidence is still nοt sufficient. Treatment of subserosal myomas of reasonable size is not necessary for fertility reasons. The results of endoscopic and open myomectomy are similar; thus, endoscopic treatment is the recommended approach due to its advantages in patient's postoperative course. PMID:26856931

    Whole lung lavage (WLL) is still the gold-standard therapy for pulmonary alveolar proteinosis (PAP). The few studies on the duration of the effect of WLL, belonging to a rather remote period, show significant but transient benefits. In 21 patients with idiopathic PAP, the duration of any benefit and, in 16 of them, the time course of lung function improvement (at baseline, 1 week, 6 months, 1 yr and then every 2 yrs after WLL) were evaluated. The present WLL technique takes longer, is invasively monitored and partially modified with respect to past techniques. More than 70% of patients remained free from recurrent PAP at 7 yrs. The bulk of the improvement in spirometric results was almost completely gained in the immediate post-WLL period due to the efficient clearance of the alveoli. At a median of 5 yrs, recovery of diffusing capacity of the lung for carbon monoxide was incomplete (75 +/- 19% of the predicted value) and there were residual gas exchange abnormalities (alveolar to arterial oxygen tension difference 3.6 +/- 1.5 kPa (27 +/- 11 mmHg)) and exercise limitation, probably explained by engorgement of lymphatic vessels. In conclusion, whole lung lavage for idiopathic pulmonary alveolar proteinosis is currently a safe procedure in an experienced setting, and provides long-lasting benefits in the majority of patients.

    Electrohysterography (EHG) is a promising technique for monitoring the uterine activity, based on electrical recordings on the abdominal surface. However, a quantitative estimation of the internal uterine pressure (IUP) by means of EHG is not available for clinical practice. In this paper we present a preliminary study on the estimation of the mechanical uterine activity from abdominal EHG measurements. For the EHG analysis we use two different Time Frequency Distributions (TFD): the spectrogram and the Wigner-Ville Distribution. We assume the EHG to be the sum of frequency modulated signals. Based on this assumption, the IUP is estimated from the unnormalized first moment of the TFD. Eventually, a third order polynomial model is applied to the estimated IUP in order to improve the estimate accuracy. A recent method for detection of uterine contraction by EHG is employed for comparison of the performance. The algorithms were tested on two patient recordings. The results were compared with a reference IUP which is simultaneously measured by an intrauterine catheter. The IUP estimated by our method showed a correlation coefficient with the reference IUP (R=0.93) higher than that achieved by the comparison method (R=0.85). Therefore the proposed method may be considered as a promising clinical technique for accurate non invasive IUP measurements. PMID:17946058

    It is estimated that at least 50% of fibroids are asymptomatic, but this figure is likely to be an underestimate as it is based on women in whom fibroids are found incidentally during another procedure (e.g. cervical screening), and there is little, if any, data from population studies on the true incidence of fibroids. If a prevalence of 50% by 50 years of age is accepted, a large number of women have asymptomatic fibroids. Working on the cliché, 'if it ain't broken, don't fix it', it may seem surprising that there should be a chapter dedicated to the issue of asymptomatic fibroids, since the simplistic approach might be to leave the asymptomatic fibroids well alone. However, asymptomatic fibroids may become symptomatic in the future, so it may be wiser to treat fibroids before they grow to a size when they become symptomatic, or treatment becomes more challenging, especially in young women who may desire fertility at a later stage, and in view of the fact that many women are starting their families in their mid-thirties when they have a 30% chance of having a fibroid(s). Despite their common occurrence, fibroids are still poorly understood. It is not known why they form in the first place, what determines their number and ultimate size, the best treatment approaches, or the factors that determine which women develop symptoms. Even when women present with disorders such as infertility, pelvic pain and abnormal bleeding, it is not always possible to be certain that a given myoma is not simply an innocent bystander rather than the cause of the symptom. This chapter addresses the challenging issue of what to do when fibroids are diagnosed incidentally. Firstly, there is the need to ascertain that the pelvic mass palpated is indeed a fibroid, and not an early, more sinister tumour, especially if conservative management is adopted. In addition, there is the issue of size, position and potential for becoming symptomatic at a later date. With the availability of uterine

    Uterine fibroids are the most common pelvic tumors in women of reproductive age. The cause of development of uterine fibroids is still unknown, however recent cytogenetic and genetic studies led to advancement in understanding of etiology of these tumors. In accordance with the latest findings up to 40% of uterine fibroids bear some chromosomal abnormalities. The most common are aberration of chromosomes 6, 7, 12 and 14. Uterine fibroids have been linked to mutations of fumarate hydratase (FH) gene. Germline mutations in FH gene cause autosomal dominant syndromes MCUL1 (multiple cutaneous and uterine leiomyomata) and HLRCC (hereditary leiomyomatosis and renal cell cancer), characterized by multiple uterine and cutaneous leiomyomata and renal cancer. This paper reviews recent findings in the role of genetic in etiology of uterine fibroids. PMID:22536642

    Thirty-eight guttural pouch lavages from 19 clinically healthy horses were collected transendoscopically. Cytological examination and bacteriological culture of the samples were carried out. All 38 lavages assessed for cytology contained less than five per cent neutrophils and could be termed as cytologically 'normal'. In none of the lavages did the neutrophil count vary between five and 25 per cent or exceed 25 per cent, which are the borderlines for being termed 'reactive' or 'pathological', respectively. Epithelial cells were the most commonly represented cell type in all lavages. Bacteriological culture was positive in 16 out of 38 lavages, but specific pathogenic bacteria were not cultivated in any of them, and only transient microflora was present. Although the relationship between the presence of specific bacteria, neutrophil count and total cell count could not be statistically evaluated due to the absence of 'reactive' and 'pathological' lavages, transendoscopic lavage appears to be a reliable method for obtaining a sample for bacteriological culture.

    OBJECTIVE: To assess whether joint lavage, viscosupplementation and triamcinolone improve joint pain, function and quality of life in patients with severe hemophilic arthropathy. METHODS: Fourteen patients with knee and/or ankle hemophilic arthritis with and without involvement of other joints underwent joint lavage and subsequent injection of hylan G-F20 and triamcinolone in all affected joints. The patients answered algo-functional questionnaires (Lequesne and WOMAC), visual analog scale for pain (VAS) and SF-36 preoperatively, and at one, three, six and twelve months postoperatively. RESULTS: Sixteen knees, 15 ankles, 8 elbows and one shoulder were treated in 14 patients. Six patients had musculoskeletal bleeding [ankle (1), leg muscle (2) and knees (4)] at 3 months affecting the results. Pain did not improve significantly. Function improved (WOMAC p=0.02 and Lequesne p=0.01). The physical component of SF-36 improved at all time points except at 3 months, with best results at one-year follow-up (baseline = 33.4; 1 month = 39.6; 3 months= 37.6; 6 months 39.6 and 1 year = 44.6; p < 0.001). CONCLUSION: Joint lavage followed by injection of triamcinolone and hylan G-F20 improves function and quality of life progressively up to a year, even in severe hemophilic arthropathy.

    Roentgenograms and gallium-67 scans and gallium-67 counts of BAL fluid samples, together with differential cell counts, have proved to be useful in assessing activity and lung involvement in sarcoidosis. In active pulmonary sarcoidosis gallium-67 scans are usually positive. Quantitation of gallium-67 uptake in lung scans, however, may be difficult. Because gallium-67 uptake and cell counts in BAL fluid may be correlated, we set out to investigate gallium-67 activity in BAL fluid recovered from patient of different groups. Sixteen patients with recently diagnosed and untreated sarcoidosis, nine patients with healthy lungs, and five patients with CFA were studied. Gallium-67 uptake of the lung, gallium-67 activity in the lavage fluid, SACE and LACE levels, and alpha 1-AT activity were measured. Significantly more gallium-67 activity was found in BAL fluid from sarcoidosis patients than in that from CFA patients (alpha = .001) or patients with healthy lungs (alpha = .001). Gallium-67 activity in BAL fluid could be well correlated with the number of lymphocytes in BAL fluid, but poorly with the number of macrophages. Subjects with increased levels of SACE or serum alpha 1-AT showed higher lavage gallium-67 activity than did normals, but no correlation could be established. High gallium-67 activity in lavage fluid may be correlated with acute sarcoidosis or physiological deterioration; low activity denotes change for the better. The results show that gallium-67 counts in BAL fluid reflects the intensity of gallium-67 uptake and thus of activity of pulmonary sarcoidosis.

    BACKGROUND: Whole gut lavage is currently used as preparation before radiological or endoscopic examination of the large bowel. AIM: To validate the gut lavage technique for the assessment of mucosal inflammation, by measuring intestinal IgG and interleukin 1 beta (IL-1 beta) in the fluid obtained. PATIENTS: Sixteen children with Crohn's disease (CD), 14 with ulcerative colitis (UC), and 22 age matched controls. METHODS: Isotonic, non-absorbable polyethylene glycol based lavage solution was given orally or by nasogastric tube. Clear fluid was collected, filtered, and treated with protease inhibitors. IgG, IL-1 beta and IL-1-receptor antagonist (IL-1-ra) were measured by sandwich enzyme linked immunosorbent assay (ELISA). RESULTS: In patients with UC and CD, IgG and IL-1 beta levels were significantly (p < 0.001) higher than in controls. A positive correlation (p < 0.05) was found with disease activity scores. IL-1-ra levels were not significantly different in UC and CD, when compared with controls, but the IL-1-ra:IL-1 beta ratio was significantly (p < 0.01) lower in patients with UC and CD, and negatively (p < 0.001) correlated with IgG levels in lavage fluid. CONCLUSIONS: Gut lavage fluid IgG and IL-1 beta levels and IL-1-ra:IL-1 beta ratio may provide objective discrimination between active and inactive disease in children with inflammatory bowel disease.

    Objective To evaluate uterine development of women with Turner syndrome (TS) receiving conventional medical care. Study design In a cross sectional study we used ultrasound for uterine evaluation in 86 women with TS aged 18–45 years participating in an intramural NIH study, and who had abnormal karyotypes in >70% of white blood cells. Outcomes were uterine dimensions and shape. Information on hormone treatment was obtained by personal interview. Results Twenty five percent had a mature in size and shape uterus, and 31% had an immature uterus, with the remainder in a transitional category. Twenty percent of all participants were not taking hormone replacement (HRT) in the preceding year. The majority on treatment were taking conjugated estrogens or oral contraceptives. Factors associated with uterine maturity were history of spontaneous puberty, and duration and type of HRT, with estradiol based treatment being the most effective. The age at starting HRT was not a critical factor. Conclusions Women with TS may develop a normal uterus even at a late start of HRT given adequate duration of treatment and regardless of karyotype.

    Usefulness of bronchoalveolar lavage fluid (BALF) and pleural cavity lavage fluid (PLF) as an experimental material was evaluated for the assessment of pulmonary toxicity of chemicals in rats. From the viewpoint of safety, isoflurane can be used for euthanasia/anesthesia because there was no difference in biological properties of BALF between diethyl ether and isoflurane. Here, we also recognized phosphate buffered saline (PBS) and distilled water equally as a solvent/vehicle for negative control. PLF is also provided as a useful target material as well as BALF for assessing chemical lung toxicity. To evaluate the method, we used zinc chloride as a model chemical and obtained the expected and satisfied results. We may conclude that the intratracheal treatment and combination usage of BALF and PLF as a target material is a good method for assessment of chemical pulmonary (lung and plural cavity) toxicity in rats.

    A non-invasive, digital technique was used to measure and quantify intrauterine pressure (IUP) changes in early postpartum dairy cows kept under farm conditions in order to document physiological changes in uterine contractility after uncomplicated calvings. In addition, possible relationships between characteristics of uterine contractility and blood ionized calcium (Ca(2+))-concentrations were investigated. Recordings of uterine contractility were made by using a transcervically inserted open tip catheter in 12 healthy cows during their first 48h after calving. The IUP recording technique appeared easily applicable under farm conditions. Although mean frequency (FREQ), amplitude (AMP) and area under the curve (AUC) of the myometrial contractions significantly decreased due to time, untreated early postpartum cows showed a high variability in characteristics of uterine contractility. There was no correlation between blood Ca2+ -concentrations and any of the contractility parameters. PMID:15935846

    In this study, an attempt is made to evaluate certain parameters that might indicate the beginning of a certain fibrogenic activity in the lung parenchyma, even before such changes become visible on the chest x-ray. The hypothesis is that studies such as certain bronchoalveolar immunological characteristics and Gallium-67 lung scans may be more sensitive indicators of parenchymal lung damage in response to asbestos inhalation than conventional radiographic criteria. If so, then in those cases where the criteria for the diagnosis of asbestosis lack the presence of parenchymal changes, it would be unwise to deny the diagnosis unless further investigation, such as the bronchoalveolar lavage fluid analysis and the Gallium-67 lung scan techniques, are made available. The most significant laboratory parameter for bronchoalveolar lavage, in this study, is that of Neutrophils (PMNs). All three asbestos-exposed groups showed no differences when compared with each other, while such differences were statistically significant when such groups were separately compared with the normal comparison group. A similar finding existed also when the Helper: suppressor T-Cell ratios were compared, and found to be higher in all the asbestos-exposed groups.

    Ingestion of an electrolyte lavage solution containing polyethylene glycol 3350 and sulfate is an effective method of cleansing the colon for diagnostic studies. Polyethylene glycol and sulfate are considered poorly absorbed from the gastrointestinal tract. Because of the quantities administered, concern exists about potential toxicity of absorption of even a small percentage, particularly for polyethylene glycol. We measured the urinary excretion of both polyethylene glycol and sulfate in normal subjects and inflammatory bowel patients. Absorption of polyethylene glycol can be assessed by measuring recovery in urine, as 85%-96% of an intravenous load is excreted in urine. Similarly, appreciable sulfate absorption would exceed renal tubular reabsorption and result in increased urinary excretion. Mean percent polyethylene glycol load recovered in urine was minimal and similar for normal (0.06%) and inflammatory bowel (0.09%) subjects. Urinary sulfate excretion after lavage was also similar for both groups and was not different from baseline. These results do not suggest the likelihood of toxicity due to polyethylene glycol 3350 or sulfate absorption during gut lavage with this solution. PMID:3699408

    This report describes a case of spontaneous bleeding from uterine vessels presenting as hyperstimulation and fetomaternal distress at term. A 40-week primigravid woman underwent an emergency caesarean section for fetal distress, which unexpectedly revealed a spontaneous haemoperitoneum. Clinical assessment and investigations postoperatively gave a diagnosis of a right-sided uterine artery aneurysm that, it was believed, had ruptured, causing the haemoperitoneum. This was successfully treated postnatally using interventional radiological techniques leading to expeditious maternal recovery and discharge home. PMID:26323974

    This case report presents a clinical pregnancy after ulipristal acetate (UA) to decrease uterine fibroid size. A 37-year-old patient, gravida 1, abortus 1, with uterine fibroids was treated with 5 mg of UA daily for 13 weeks starting eight months after a multiple laparotomic myomectomy. Fibroid shrinkage and restoration of the morphology of endometrial cavity were evaluated in order to allow a subsequent pregnancy. A decrease of the uterine fibroids and a normal morphology of the endometrial cavity were noted by transvaginal ultrasound after treatment. An endometrial biopsy excluded histologic endometrial changes. Three months after the end of UA the patient reported amenorrhea for 5 weeks and a clinical pregnancy was confirmed with transvaginal ultrasound. She underwent a subsequent uneventful pregnancy. Thus, the spontaneous pregnancy after UA to reduce fibroid size may support the potential clinical utility of this selective progesterone receptor modulator in the management of women with pregnancy desire and uterine fibroids after a prior myomectomy. Patients who refuse a new surgical procedure and/or those who are going to undergo assisted reproductive techniques would benefit from UA. It effectively shrinks fibroids, avoids risks of a new surgical procedure, and allows an immediate attempt at conception after the end of treatment. PMID:25143845

  12. Biological Roles of Uterine Glands in Pregnancy

    2014-01-01

    All mammalian uteri contain glands in the endometrium that synthesize or transport and secrete substances essential for survival and development of the conceptus (embryo/fetus and associated extraembryonic membranes). This review summarizes information related to the biological roles of uterine glands and their secretions in blastocyst/conceptus survival and implantation, uterine receptivity, and stromal cell decidualization in humans and animal models. The infertility and recurrent pregnancy loss observed in the ovine uterine gland knockout (UGKO) model unequivocally supports a primary role for uterine glands and, by inference, their secretions present in uterine luminal fluid in survival and development of the conceptus. Further, studies with mutant and progesterone-induced UGKO mice found that uterine glands and their secretions are required for establishment of uterine receptivity and blastocyst implantation as well as stromal cell decidualization. Similarly in humans, uterine glands and their secretory products are likely critical regulators of blastocyst implantation, uterine receptivity, and conceptus growth and development during the first trimester. Circumstantial evidence suggests that deficient glandular activity may be a causative factor in pregnancy failure and complications in humans. Thus, an increased understanding of uterine gland biology is important for diagnosis, prevention and treatment of fertility and pregnancy problems in mammals. PMID:24959816

    A five-year-old female cat weighing 3 kg was presented by the owner after noticing a large pink, bilobed mass protruding through the vulva during labour. The cat was in good condition, with appropriate lactation, and the newborn kittens were nursing normally. The uterus was not reverted or invaginated at examination, and there was rupture of the mesovarium, mesometrium and uterine-vaginal connection around the cervix. Manual reduction of the prolapsed uterus was not possible because of torn ligaments. A coeliotomy was performed to remove the ovaries, and the apex of the uterine horns was passed by the vaginal route. The remaining part of the mesometrium was disconnected, and the prolapsed uterus was removed. The queen and kittens were discharged from the hospital on the second day after surgery. An unusual feature of this case is that the prolapse was complete, without eversion of any part of the uterus through a vaginal tear. PMID:24697408

    Background. Estimates of unexpected uterine sarcoma following surgery for presumed benign leiomyoma that use age-stratification are lacking. Patients and Methods. A retrospective cohort of 2,075 patients that had undergone myomectomy was evaluated to determine the case incidence of unexpected uterine sarcoma. An aggregate risk estimate was generated using a meta-analysis of similar studies plus our data. Database-derived age distributions of the incidence rates of uterine sarcoma and uterine leiomyoma surgery were used to stratify risk by age. Results. Of 2,075 patients in our retrospective cohort, 6 were diagnosed with uterine sarcoma. Our meta-analysis revealed 8 studies from 1980 to 2014. Combined with our study, 18 cases of leiomyosarcoma are reported in 10,120 patients, for an aggregate risk of 1.78 per 1,000 (95% confidence interval [CI]: 1.1–2.8) or 1 in 562. Eight cases of other uterine sarcomas were reported in 6,889 patients, for an aggregate risk of 1.16 per 1,000 (95% CI: 0.5–4.9) or 1 in 861. The summation of these risks gives an overall risk of uterine sarcoma of 2.94 per 1,000 (95% CI: 1.8–4.1) or 1 in 340. After stratification by age, we predict the risk of uterine sarcoma to range from a peak of 10.1 cases per 1,000, or 1 in 98, for patients aged 75–79 years to <1 case per 500 for patients aged <30 years. Conclusion. The risk of unexpected uterine sarcoma varies significantly across age groups. Our age-stratified predictive model should be incorporated to more accurately counsel patients and to assist in providing guidelines for the surgical technique for leiomyoma. PMID:25765878

    Uterine artery embolization (UAE) as a treatment option for fibroids was first reported by Ravina in 1995. Although rapidly adopted by enthusiasts, many were skeptical and its introduction varied widely across the globe. It was not until randomized controlled trials and registries were published and national guidance statements issued that UAE was accepted as a safe and proven treatment for fibroids. The technique is now established as one of the treatment options to be discussed with patients as an alternative to surgery for fibroid-associated heavy menstrual bleeding. Research is on-going to evaluate the relative merits of UAE compared with other medical and surgical treatment options for heavy menstrual bleeding, particularly for women wishing to maintain their fertility.

    Uterine leiomyomas are benign tumors arising from uterine smooth muscle. Although their pathogenesis remains unclear, they are the most common tumor of the female reproductive tract, occurring in as many as half of women older than 35 years. Uterine leiomyomas represent the most common benign tumors of the female reproductive tract. Giant uterine leiomyomas are very rare and represents a great diagnosis and therapeutic challenge. Uterine leiomyoma is one of the most frequent types of tumours and it is diagnosed in 20-40% of the women of reproductive age. Until the age of 50, approximately 70% of the white women and less than 80% of the black women will have had at least one leiomyoma. The frequency of the emergence of uterine leiomyoma in black women is significantly higher than in white women. PMID:27125088

    Bacterial contamination of the uterine lumen is common in cattle after parturition, often leading to infection and uterine disease. Clinical disease can be diagnosed and scored by examination of the vaginal mucus, which reflects the presence of pathogenic bacteria such as Escherichia coli and Arcanobacterium pyogenes. Viruses may also cause uterine disease and bovine herpesvirus 4 (BoHV-4) is tropic for endometrial cells, causing a rapid cytopathic effect. The elimination of pathogens by the innate immune system is dependent on pattern recognition receptors binding pathogen-associated molecules. Uterine epithelial and stromal cells express receptors such as Toll-like Receptor 4 that binds E. coli lipopolysaccharide. The infertility associated with uterine disease is caused by damage to the endometrium and disruption of ovarian cyclic activity. Bacteria modulate endometrial prostaglandin secretion, and perturb ovarian follicle growth and function. Understanding the molecular basis of uterine disease will lead to novel approaches to treating infertility. PMID:18329302

    Uterine fibroids (UF) are common, benign gynecologic tumors, affecting one in three to four women, with estimates of up to 80%, depending on the population studied. Their etiology is not well established, but it is under the influence of several risk factors, such as early menarche, nulliparity and family history. More than 50% of affected women are asymptomatic, but the lesions may be related to bothersome symptoms, such as abnormal uterine bleeding, pelvic pain and bloating or urinary symptoms. The treatment of UF is classically surgical; however, various medical options are available, providing symptom control while minimizing risks and complications. A large number of clinical trials have evaluated commonly used medical treatments and potentially effective new ones. Through a comprehensive literature search using PubMed, EMBASE, CENTRAL, Scopus and Google Scholar databases, through which we included 41 studies out of 7658 results, we thoroughly explored the different pharmacological options available for management of UF, their indications, advantages and disadvantages.

    Myomas are observed in about 3-12% of pregnant women. Uterine fibroids may affect the outcome of pregnancy. The presence of myomas - in particular of myomas that distort the uterine cavity and larger intramural myomas - has been associated with infertility. In the case of pregnancy, it has been linked to an increased risk of spontaneous abortion, fetal malpresentation, placenta previa, preterm birth, cesarean section, and peripartum hemorrhage. Although fibroids may negatively affect pregnancy outcome, the impact of their treatment, particularly in quantitative terms, is unclear. Hysteroscopic myomectomy is the treatment of choice for submucous fibroids. The comparative efficacy of laparoscopic, laparotomic, or new modalities of treatment of intramural fibroids is not known. Up to date the choice and modalities of treatment of submucous fibroids should not be based on sound evidence but on clinical concerns and the skill of each center. PMID:26723475

    1979-01-01

    Recent studies have suggested that intranasal administration of antigen can induce local cell-mediated immunity in lung lavage cells. The present study was designed to examine the changes in composition of lung lavage cells and their capacity to produce the lymphokine migration inhibitory factor after intranasal immunization with BCG in guinea pigs. Results indicate that guinea pigs responded to respiratory tract BCG infection with an increase in immunocompetent cells in the bronchoalveolar tract and with production of migration inhibitory factor. After local pulmonary BCG administration, the total number of cells increased as compared with that of the uninfected animals, the increase being statistically significant within 2 weeks. This marked increase in the total cell population is due to a more than doubling of the number of macrophages in the lavage fluid. Animals also developed at this time positive delayed hypersensitivity to intradermally administered purified protein derivative. A significant increase in the total lymphoid cells and macrophage population was observed again at 6 weeks after sensitization, suggesting that the response is biphasic in nature. At 6 weeks, however, there was also a significant rise in total lymphocytes and T cell population in addition to macrophage numbers. This increase in T cells correlated with an increase in production of migration inhibitory factor in the presence of purified protein derivative. These data suggest that the immune response of the respiratory tract after BCG challenge involves increased recruitment of immunocompetent cells locally at the site of infection and that these cells are capable of producing effector molecules in terms of the elaboration of migration inhibitory factor.

    Hamsters were exposed to an aerosol of fused aluminosilicate particles (FAP) labeled with [sup 57]CO. Three groups of animals were given bronchopulmonary lavage, beginning at either 1 week, 1 month, or 6 months after exposure. Each treated group was lavaged eight times over a period of 25 days. Each lavage involved 10 saline washes of the lungs. For each group, about 60-70% of the body content of [sup 57]CO at the start of lavage treatment was removed; nearly half of this was recovered in the first two lavages. A positive correlation was demonstrated between the macrophage content and [sup 57]Co activity of the washings. The subsequent fractional clearance rate of [sup 57]Co from lavaged animals was not significantly different from that in a group of untreated control animals. 30 refs., 2 figs., 2 tabs.

    This pilot study describes the effect of intraoperative peritoneal lavage (IOPL) on bacterial counts and outcome in clinical cases of septic peritonitis. Intraoperative samples were cultured before and after IOPL. Thirty-three dogs with presumed septic peritonitis on the basis of cytology were managed surgically during the study period. Positive pre-lavage bacterial cultures were found in 14 cases, 13 of which were a result of intestinal leakage. The post-lavage cultures showed fewer isolates in 9 cases and in 1 case became negative. The number of dogs with a decrease in the concentration of bacteria cultured from pre-lavage to post-lavage samples was not statistically significant. There was no significant effect of the change in pre- to post-lavage culture, single versus multiple types of bacteria, selection of an appropriate empiric antimicrobial on survival or the need for subsequent surgery.

    Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which 'conversion theory' was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

    Uterine sarcomas are rare, highly malignant tumours comprising < 1 % of all gynaecologic malignancies. To evaluate clinical presentation, histolopathologic pattern and outcome of uterine sarcomas presenting to a tertiary referral centre over an 8 year period (2004-2012). All histologically proven uterine sarcomas were retrospectively analysed. Clinical presentation, histology, treatment and outcome were analysed. Mean age was 42 years. Predominant histopathology was endometrial stromal sarcoma (n = 13); 9 were low grade, carcinosarcoma (n = 8) and leiomyosarcoma (n = 2). Fourteen patients had Stage I disease, 3 Stage II, 4 Stage III and 2 were Stage IV at presentation. Patients with disease confined to uterus received no adjuvant treatment (61 %). Of these, 11 were endometrial stromal sarcoma (7 were low grade) and 3 were carcinosarcomas. Four patients received adjuvant EBRT following hysterectomy (17 %). Two patients who presented with metastases received palliative chemotherapy. Mean follow-up period was 46 months (0-86 months). Eleven patients (47 %) developed disease recurrence. Seven (30 %) had local recurrence, while 4 (17 %) developed pulmonary metastases. A total of eight patients died and all deaths were within 1 year of recurrence. The only prognostic factor that correlated with survival was the stage of disease at diagnosis. PMID:27217670

    Uterine rupture in labour requires an emergency caesarean section. In women with a uterine scar, either from gynaecological surgery or from a previous caesarean section, it is well documented that the risk of rupture is higher than in those without. Spontaneous uterine rupture in a uterus with fibroids during pregnancy or labour is extremely rare. We present a case of a 33-year-old, unbooked pregnant woman from Nigeria who had a uterine rupture secondary to fibroids. She required an emergency caesarean section in labour. The fibroids were not removed. Her baby was born alive and in good condition and she made an uneventful recovery. PMID:25199188

    Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by the deposition of lipoproteinaceous materials in the bronchoalveolar tree. Whole lung lavage was introduced in the 1960s and remains a treatment of choice for PAP. The main anesthetic challenge of whole lung lavage is maintaining adequate oxygenation during the procedure. We describe 2 interesting patients with PAP, the anesthetic challenges faced during the lung lavage, and discuss the management strategies adopted in each case. PMID:26795910

    A patient with chronic eosinophilic pneumonia was evaluated using bronchoalveolar lavage, technetium-99m glucoheptonate, and transbronchial lung biopsy. Bronchoalveolar lavage revealed 43 percent eosinophils and correlated well with results of transbronchial lung biopsy. Technetium-99m glucoheptonate lung imaging demonstrated intense parenchymal uptake. After eight weeks of corticosteroid therapy, the bronchoalveolar lavage eosinophil population and the technetium-99m glucoheptonate uptake had returned to normal. We suggest that bronchoalveolar lavage, with transbronchial lung biopsy, is a less invasive way than open lung biopsy to diagnose chronic eosinophilic pneumonia. The mechanism of uptake of technetium-99m glucoheptonate in this disorder remains to be defined.

    Radiation pneumonitis is a life-threatening result of therapeutic thoracic irradiation, yet its mechanisms are poorly understood. We studied the effects of unilateral lung irradiation (3,000 rad) in sheep from the immediate response to the later development of radiation pneumonitis. We defined radiation pneumonitis by its diagnostic clinical feature, radiographic infiltration of the irradiated zone with a straight margin corresponding to the radiation port. The immediate response in the few hours after irradiation was characterized by cough, labored respiration, hypoxemia (arterial PO{sub 2} decreased 19 Torr), mild pulmonary hypertension (pulmonary arterial pressure increased 20%), and lymphopenia. Hemodynamics and gas exchange returned to normal by day 2 but became abnormal again before or during radiation pneumonitis at 32 +/- 2 days. Respiratory distress, hypoxemia, and pulmonary hypertension recurred during radiation pneumonitis. Bronchoalveolar lavage during radiation pneumonitis contained increased neutrophils (19 +/- 4%, control = 7%), increased protein (0.27 +/- 0.1 g/dl, control = 0.12 +/- 0.03), and severely impaired ability to lower surface tension. Alveolar macrophages from both lungs during unilateral radiation pneumonitis exhibited impaired generation of superoxide after phorbol myristate (only a 30% increase). Normal control alveolar macrophages increased superoxide production after stimulation greater than 400%. We conclude that unilateral lung irradiation in sheep causes a mild immediate response followed by radiation pneumonitis at 1 mo. Unilateral radiation pneumonitis in this model is associated with ipsilateral neutrophilic alveolitis, increased bronchoalveolar lavage protein, and impaired surfactant function, as well as bilateral functional abnormalities of alveolar macrophages.

    Abstract Primary uterine non-Hodgkin's lymphoma is extremely rare accounting for <1% of all extranodal non-Hodgkin's lymphomas. Imaging findings of primary uterine lymphoma have rarely been reported before. We present magnetic resonance imaging (MRI) and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT findings in a patient with primary uterine peripheral T-cell lymphoma. A 27-year-old female presented with intermittent fever with neutropenia for 7 months. MRI showed an ill-defined mass involved both the uterine corpus and cervix, resulting in diffuse enlargement of the uterus. This mass showed inhomogeneous hypointensity on unenhanced T1-weighted images, hyperintensity on diffusion-weighted imaging, relative hypointensity compared to the surrounding myometrium on T2-weighted images and lower enhancement than the surrounding myometrium on enhanced T1-weighted images. FDG PET/CT showed intense FDG uptake in the thickened wall of the uterine corpus and cervix with SUVmax of 26.9. There were multiple hypermetabolic lymph nodes in the pelvis and retroperitoneum. Uterine curettage and CT-guided biopsy of the uterine mass revealed peripheral T-cell lymphoma. Bone marrow biopsy revealed no evidence of lymphomatous involvement. The imaging and pathologic findings were consistent with primary uterine lymphoma. After 3 circles of chemotherapy, follow-up enhanced MRI showed decreased thickness of the uterine wall. Despite its rarity, primary uterine non-Hodgkin's lymphoma should be taken into consideration when a uterine tumor shows large size, relative hypointesity on both T2-weighted images and enhanced T1-weighted images compared to the surrounding myometrium, and intense FDG uptake on PET/CT. MRI may be helpful for describing the relationship between the tumor and adjacent structures. FDG PET/CT may be useful for tumor detection and staging. PMID:27124063

    In recent years, there has been increasing evidence of the potential pathogenic significance of equine gammaherpesviruses in the horse. In humans, cattle and mice, gammaherpesviruses have already been associated with uterine infection. The aim of the present study was to investigate the presence of gammaherpesviruses in uterine flushings of mares with reproductive problems and to evaluate if there was a possible statistical association with clinical and laboratory findings in these cases. A total of 80 uterine flushings were collected from 61 mares with different reproductive problems and these were tested for equine herpesviruses (EHV) 1-5 by PCR. In the case of each mare in the study, the age, history of infertility, presence of anatomical defects in the reproductive tract, presence of systemic or local disease at time of sampling, phase in the oestrous cycle, post-partum interval, nature of uterine lavage performed (low versus large volume lavage), cytological and bacteriological examination results from the uterine flushing, and PCR herpesvirus results were recorded. Univariate analysis and multivariable logistic regression models were used to identify possible statistical associations and risk factors. Nine out of 61 mares (14.7%) had EHV-5 DNA in their uterine flushings. Co-infections with EHV-1 and EHV-2 were present in two cases. Of all the variables analyzed, only the cytological examination findings were associated with EHV-5 PCR positive results, both on univariate and multivariable analysis, especially in cases with an inflammation score of 3. It is postulated that presence of EHV-5 infection in the non-pregnant uterus may have a role to play in reproductive dysfunction and have a negative consequence on the pregnant uterus. Additional studies involving both healthy mares and mares with reproductive problems need to be performed, however, to elucidate whatever role equine gammaherpesviruses may play in the reproductive tract.

    Normal pregnancy involves dramatic remodeling of the uterine vasculature, with abnormal vascular adaptations contributing to pregnancy diseases such as preeclampsia. The peptide hormone relaxin is important for the renal and systemic hemodynamic adaptations to pregnancy, and has been shown to increase arterial compliance and outward hypertrophic remodeling. Therefore, we investigated the possibility that relaxin acts on its receptor, RXFP1, to mediate uterine artery compliance in late pregnancy and increase uterine blood flow velocity in rats. RXFP1 was predominantly localized to the tunica media vascular smooth muscle cells in the uterine artery, although receptors were also detected in endothelial cells. Highest expression of Rxfp1 in the uterine artery occurred in estrus and early pregnancy. Isolated uterine arteries from late pregnant rats treated with a monoclonal antibody against circulating relaxin (MCA1) had significantly increased vessel wall stiffness compared with controls, with no reduction in wall thickness. Chronic infusion of relaxin (4 μg/h, osmotic minipump) for 5 d in nonpregnant rats significantly increased uterine artery blood flow velocity. Overall, these data demonstrate a functional role for relaxin in mediating uterine artery compliance in pregnant rats, which may be necessary to maintain adequate uterine blood flow to the uterus and placenta.—Vodstrcil, L.

    All mammalian uteri contain glands in the endometrium that synthesize or transport and secrete substances essential for survival and development of the conceptus (embryo/fetus and associated extraembryonic membranes). This review summarizes information related to the biological roles of uterine glands and their secretions in uterine receptivity, blastocyst/conceptus survival and implantation, and stromal cell decidualization. Studies with the ovine uterine gland knockout (UGKO) model support a primary role for uterine glands and, by inference, their secretions present in uterine luminal fluid histrotroph for conceptus survival and development. In rodents, studies with mutant and progesterone-induced UGKO mice found that uterine glands and their secretions are unequivocally required for establishment of uterine receptivity and blastocyst implantation and also may influence blastocyst trophectoderm activation and stromal cell decidualization in the uterus. Similarly in humans, histotroph from uterine glands appears critical for blastocyst implantation, uterine receptivity, and conceptus nutrition during the first trimester and uterine glands likely have a role in stromal cell decidualization. An increased understanding of uterine gland biology is important for diagnosis, prevention and treatment of fertility problems, particularly infertility and recurrent pregnancy loss, in domestic animals and humans.

    The objective of this study was to investigate the effects of puerperal uterine disease on uterine blood flow using trans-rectal Doppler sonography. Lactating Holstein Friesian cows (n=44) were divided into two groups based on whether they were healthy (UD-; n=23) or had uterine disease (UD+; n=21) defined as retained fetal membranes and/or metritis. General clinical examination, vaginoscopy, trans-rectal palpation, and trans-rectal B-Mode sonography were conducted on Days 8, 11, 18, 25 and then every 10 days until Day 65 after calving. Doppler sonography of the uterine arteries was conducted on Day 8, during diestrus after the second ovulation (Days 40-60 after calving) and during diestrus before breeding (Days 63-75 after calving). Cows with uterine disease had greater (P<0.05) uterine size as assessed trans-rectally compared with cows of the UD group. Sonographic measurements on Day 11 after parturition revealed a greater (P<0.05) horn diameter in cows of the UD+ than in the UD- group. Both uterine size and uterine horn diameter decreased more earlier following parturition (P<0.05) in cows of the UD- group. Blood flow volume (BFV) was greater and pulsatility index was less on Day 8 after calving in cows of UD+ than UD- group (P<0.05). In cows of the UD-, but not in those of the UD+ group, there was a further reduction in BFV subsequent to Day 45 after calving (P<0.05). The results of this study show that uterine blood flow measures by trans-rectal Doppler sonography are affected by puerperal uterine disease. PMID:24275717

Interstitial irradiation was the choice of treatment for early carcinoma of the prostate, carcinoma of the anal canal less than T2, recurrent carcinoma of the uterine cervix, and carcinoma of the cervical stump. The authors' experience in treating recurrent carcinoma of the uterine cervix with interstitial irradiation is the basis for the indications for selecting the technique of interstitial irradiation presented.

    Purpose. To evaluate the potential of uterine artery embolization to minimize blood loss and facilitate easier removal of fibroids during subsequent myomectomy. Methods. This retrospective study included 22 patients (median age 37 years), of whom at least 15 wished to preserve their fertility. They presented with at least one fibroid (mean diameter 85.6 mm) and had undergone preoperative uterine artery embolization (PUAE) with resorbable gelatin sponge. Results. No complication or technical failure of embolization was identified. Myomectomies were performed during laparoscopy (12 cases) and laparotomy (9 cases). One hysterectomy was performed. The following were noted: easier dissection of fibroids (mean 5.6 per patient, range 1-30); mean intervention time 113 min (range 25-210 min); almost bloodless surgery, with a mean peroperative blood loss of 90 ml (range 0-806 ml); mean hemoglobin pretherapeutically 12.3 g/dl (range 5.9-15.2 g/dl) and post-therapeutically 10.3 g/dl (range 5.6-13.3 g/dl), with no blood transfusion needed. Patients were discharged on day 4 on average and the mean sick leave was 1 month. Conclusion. Preoperative embolization is associated with minimal intraoperative blood loss. It does not increase the complication rate or impair operative dissection, and improves the chances of performing conservative surgery.

    Endocervicosis is considered a form of Mülleriosis affecting mainly the bladder and is comprised of endocervical-type glands and cysts. It has been rarely described in the uterine cervix where the extensive involvement of cervical and paracervical tissue poses the suspicion of malignancy, mostly minimal-deviation adenocarcinoma. We describe a case of cervical endocervicosis causing long-term symptoms leading to hysterectomy. We provide evidence that this pathology is associated with cesarean section similar with isthmocele. Its differential diagnosis is discussed. PMID:26825004

    In the past few years, several endemic outbreaks of measles have been recognised, not only in children but also in adults, with severe and, occasionally, even fatal complications, possibly due to delayed diagnosis of the disease in adult medicine and decreasing vaccination rates. Furthermore, the treatment consists of supportive measures only. We present a case of severe measles pneumonitis in a 42-year-old man, a travel returnee, proven by direct virus isolation with PCR from bronchoalveolar lavage fluid. CT findings and pulmonary function testing revealed features of obstructive bronchiolitis; the patient was successfully treated with corticosteroids. He fully recovered, and lung function measurement returned to normal values. We conclude that acute measles can present as obstructive bronchiolitis and may be successfully treated with corticosteroids. PMID:26508116

    A uterine caliper and sound consisting of an elongated body having outwardly biased resilient caliper wings and a spring-loaded slidable cervical stop. A slide on the body is operatively connected to the wings by a monofilament and operates with respect to a first scale on the body as a width indicator. A rod extending longitudinally on the body is connected to the cervical stop and cooperates with a second scale on the body as a depth indicator. The instrument can be positioned to measure the distance from the outer cervical ostium to the fundus, as read on said second scale. The wings may be allowed to open by moving the slide, and when the wings engage the utero-tubal junctions, the width may be read on said first scale. By adjustment of the caliper wings the instrument may be retracted until the resistance of the inner ostium of the cervix is felt, enabling the length of the cervical canal to be read directly by the position of the longitudinal indicator rod with respect to said second scale. The instrument may be employed to measure the width of the uterine cavity at any position between the inner ostium of the cervix and the fundus.

    2014-01-01

    Uterine rupture is a rare life-threatening complication. It mainly occurs in the third trimester of pregnancy and is rarely seen during the first or second trimesters. Our centre experienced three important cases of uterine rupture. First case: spontaneous uterine rupture at 14 weeks of pregnancy, which was diagnosed at autopsy. It was misled by the ultrasound finding of an intrauterine pregnancy, and searching for other non-gynaecological causes delayed the urgent obstetric surgical management. Second case: ruptured uterus at 24 weeks following medical termination due to foetal anomaly. It was diagnosed only at laparotomy indicated for failed medical termination and chorioamnionitis. Third case: uterine rupture at 21 weeks of pregnancy in a patient with gastroenterology symptoms. In these reports, we have discussed the various risk factors, presentations, course of events and difficulties in diagnosing uterine rupture. The study concludes that the clinical presentation of uterine ruptures varies. It occurs regardless of gestational age. Ultrasound findings of intrauterine pregnancy with free fluid do not exclude uterine rupture or ectopic pregnancy. Searching for non-gynaecological causes in such clinical presentations might delay crucial surgical intervention, which leads to unnecessary morbidity, mortality or loss of obstetrics function.

    Infertility due to the inability of the uterus to carry a pregnancy ranks among the most unresolved issues in reproductive medicine. It affects millions of women worldwide who have congenital or acquired uterine affections, often requiring hysterectomy, and potentially represents a considerable fraction of the general infertile population. Patients suffering from severe uterine infertility are currently compelled to go through gestational surrogacy or adoption; both approaches, unfortunately, deprive them of the maternal experience of pregnancy and birth. Uterine transplantation represents an outstanding, yet complex, perspective to alleviating definitive uterine infertility. In the past decades, a number of scientific experiments conducted both in animals and women, focusing on uterine transplantation, have led to promising results. Collectively, these findings undoubtedly constitute a sound basis to clinically apply uterine transplantation in the near future. This paper is, however, an overview not only of the extent and limitations of accumulated scientific knowledge on uterine transplantation, but also its ethical implications, in an effort to define the actual place of such an approach among the therapeutic arsenal for alleviating infertility.

    Normal pregnancy involves dramatic remodeling of the uterine vasculature, with abnormal vascular adaptations contributing to pregnancy diseases such as preeclampsia. The peptide hormone relaxin is important for the renal and systemic hemodynamic adaptations to pregnancy, and has been shown to increase arterial compliance and outward hypertrophic remodeling. Therefore, we investigated the possibility that relaxin acts on its receptor, RXFP1, to mediate uterine artery compliance in late pregnancy and increase uterine blood flow velocity in rats. RXFP1 was predominantly localized to the tunica media vascular smooth muscle cells in the uterine artery, although receptors were also detected in endothelial cells. Highest expression of Rxfp1 in the uterine artery occurred in estrus and early pregnancy. Isolated uterine arteries from late pregnant rats treated with a monoclonal antibody against circulating relaxin (MCA1) had significantly increased vessel wall stiffness compared with controls, with no reduction in wall thickness. Chronic infusion of relaxin (4 μg/h, osmotic minipump) for 5 d in nonpregnant rats significantly increased uterine artery blood flow velocity. Overall, these data demonstrate a functional role for relaxin in mediating uterine artery compliance in pregnant rats, which may be necessary to maintain adequate uterine blood flow to the uterus and placenta.

Several complications have been reported including expulsion and sepsis. MRI is a useful pretreatment tool to predict results and outcomes. We report a case of a 44-year-old female with a history of uterine fibroids with the largest one being intracavitary. Patient underwent uterine artery embolization that was complicated by endomyometritis that failed antibiotics, leading to sepsis and hysterectomy. PMID:27073705

    Uterine serous adenocarcinoma (USC) is rare and invasive cancer. This cancer is more often reported in the ovary, the fallopian tube, and the endometrium than uterine cervix. No matter where the tumor is located, the tumor exhibits similar histological characteristics. So when uterine cancer is proven to be serous adenocarcinoma, it is necessary to see if the tumor originated from ovary or endometrium and invaded the cervix. We report a case of a 73-year-old postmenopausal woman with USC arising near the internal os of endocervical canal, clinically misdiagnosed as uterine cervix cancer. PMID:26793684

    Myomas represent a large part of benign gynecological pathology, widely spread in fertile female population. First step to diagnose fibroids is ultrasound (US) that can be 2-dimensional (2D), 3-dimensional (3D), Color Doppler (CD) and sonohysterography (SHG). This review develops according to MUSA's sonographic features (Morphological Uterus Sonographic Assessment). One of the main topic of interest for ultrasonographer today is endo/myometrial junctional zone (JZ), because it may be useful to discern a diagnosis of myoma and adenomyosis. Another important aspect of ultrasound is the analysis of vascularization in front of a uterine lesion. Indeed, vascular pattern can be used to make differential diagnosis between myoma-adenomyosis and leiomyosarcomas. Myomas should be described accurately according to sonographic guidelines. Sonographic features correlated with symptoms should guide an appropriate surgical or medical treatment. PMID:27014801

    Spontaneous uterine contractility during the menstrual cycle is required for menstruation, gamete transport, and, most likely, embryo nidation. Abnormal uterine contractility has been linked to dysmenorrhea, a condition associated with painful uterine cramping. Based on previous studies with progesterone, we have postulated the existence of a portal system that is responsible for some degree of direct vagina-to-uterus transport of administered compounds (i.e., the "first uterine pass effect"). It is possible that treatment with uterorelaxing substances, particularly beta-adrenergic agonists, may alleviate the uterine discomfort that accompanies dysmenorrhea. However, side effects encountered with oral administration of beta-agonists limit their utility. Alternatively, vaginal delivery of beta-agonists could solve this dilemma by enhancing their efficacy and reducing side effects. Therefore, in the current study we used hysterectomy specimens and an in vitro uterine perfusion system to test the vagina-to-uterus transport of [3H]terbutaline, a well-known beta-agonist. With the use of autoradiographic and scintillation counting techniques, our results clearly show progressive diffusion of labeled terbutaline from the rim of vaginal tissue through the uterus during the first 12 hours of perfusion. This indicates that uterine targeting of terbutaline can be accomplished through vaginal administration, suggesting a new therapeutic modality in women's health care. PMID:11594537

    The localization of uterine devices by ultra-sound techniques was investigated. Seven different types of intra-uterine contraceptive devices were checked under immersion in water and in the uterus of 585 wearers of I.U.D.'s. The quality of the ultra-sound pictures is mostly determined by the type of intra-uterine device. Under optimal conditions the investigated types of I.U.D.'s produced standard ultra-sound pictures which permitted their identification. The evaluation of the localization of the intra-uterine contraceptive devices in the uterus was reasonably accurate. At first the classification of normal localization, lower segment localization and cervical localization was used, and this was later enlarged by the measurement of the distance between the uterine fundus and the end of the device closest to the fundus. It was possible to estimate the contraceptive efficiency with these measurements. In 486 cases (83%) the intra-uterine device was found in normal position. In 24 (4.1%) of the cases removal and repeat insertion of the device was suggested. In 18 (3.1%) cases the device was not localized despite normal intra-uterine localization. PMID:710881

    INTRODUCTION: Intra-operative peritoneal lavage (IOPL) is widely practised but its benefits are unclear. The frequency and pattern of its use amongst general surgeons is investigated. METHODS: A postal questionnaire was sent to 153 general surgical consultants and registrars enquiring about their use of IOPL. The surgeon was asked the volume and type of lavage fluid used, under various circumstances. RESULTS: 118 (77%) questionnaires were returned. 115 (97%) surgeons used IOPL. The majority of surgeons (61%) lavaged until the fluid was clear, 20% used more than 1 l and 17% used between 500-1000 ml. In the case of the dirty abdomen (i.e. gross pus or faecal peritonitis), 47% used saline as the lavage fluid, 38% aqueous betadine, 9% water and 3% antibiotic lavage. Similar results were found in the case of a contaminated abdomen (i.e. a breached hollow viscus). 34% of surgeons used IOPL during clean cases. 36% used water lavage during intra-abdominal cancer surgery; 21% lavaged with saline and 17% with betadine. More registrars (47%) than consultants (29%) lavaged with water during cancer surgery. Consultants, however, used more aqueous betadine. CONCLUSIONS: The frequency of use and choice of lavage fluid varies widely. The successful management of the septic abdomen rests on at least 3 tenants - systemic antibiotics, control of the source of infection and aspiration of gross contaminants. There is little good evidence in the literature to support IOPL in the management of the septic abdomen. The use of IOPL during cancer surgery is supported by in vitro evidence. The current use of IOPL, as shown by this study, appears not to be evidence based. PMID:16053685

    In the uterus of the mare, data obtained using transrectal Doppler ultrasonography indicate that uterine blood flow (UBF) is dynamic and changes throughout the estrous cycle. Degenerative lesions in the uterus are associated with subfertility and infertility. Among these lesions, vascular elastosis has been reported in aged, multiparous, and infertile mares. Angiosis of the uterine vasculature could potentially compromise UBF. The objectives of this experiment are to determine levels of UBF and perfusion of reproductively healthy mares and compare them to levels of subfertile/infertile mares affected by uterine vascular elastosis. Twenty mares were classified on the basis of degree of vascular degeneration and stage of cycle. A fluorescent microsphere technique was used to measure reproductive organ perfusion, where microspheres were injected into the left ventricle of the heart and became trapped in capillary beds in proportion to blood flow and tissue perfusion. The reproductive tract was removed, sectioned, and the fluorescent intensity evaluated to measure blood flow and perfusion. Additionally, full-thickness samples of the uterine wall were examined postmortem to further assess the degree of vascular degeneration in all layers of uterine wall. The mean value of uterine perfusion for the control mares during estrus (n = 5) was higher (P < 0.01) than that during diestrus (n = 5); 17.6 and 11.9 mL/min/100g, respectively. For the subfertile/infertile mares, the mean value of tissue perfusion was not different (P > 0.05) during estrus (n = 5) and diestrus (n = 5); 5.9 and 7.2 mL/min/100g, respectively. Uterine perfusion in subfertile/infertile mares affected by elastosis was lower than that of control mares during both estrus (P < 0.01) and diestrus (P < 0.01). The differences in baseline levels of perfusion between the control and elastosis groups indicate that elastosis of the uterine vasculature is associated with decreased uterine perfusion

    Metastatic lesions of uterine carcinosarcoma most commonly occur in the abdomen and lungs and less frequently in highly vascularized bone. We report a rare case of an 86-year-old female with uterine carcinosarcoma with metastasis to the left calcaneus. The patient had a history of uterine carcinosarcoma with hysterectomy and bilateral salpingo-oophorectomy, along with bilateral pelvic and aortic lymphadenectomy, with no adjuvant therapy. The initial pedal complaint was that of left foot pain. The initial radiographic findings were negative; however, magnetic resonance imaging scans revealed a substantial area of marrow edema in the calcaneus. An excisional biopsy was performed, and histopathologic analysis revealed adenocarcinoma with features consistent with the patient's previous uterine tumor specimen. The patient was given one treatment of chemotherapy and was discharged to a hospice, where she died of her disease 2 weeks later. PMID:23871174

    Uterine leiomyomas, or fibroids, are the most common benign tumor in reproductive aged women. Affected women may remain asymptomatic or may report symptoms related to abnormal uterine bleeding, infertility, or pelvic pain and pressure. Depending on a patient's symptomatology and reproductive plans, treatment options include expectant management, medical management (hormonal and non-hormonal), or surgical management (myomectomy or hysterectomy). In those wishing to defer surgical management, non-hormonal therapies such as non-steroidal anti-inflammatory drugs and tranexamic acid have been shown to decrease menstrual blood loss. In patients with more symptomatic leiomyomas, hormonal therapies such as gonadotropin-releasing hormone agonists and selective progesterone receptor modulators are effective at reducing leiomyoma volume, uterine size, and menstrual blood loss. This manuscript will detail the available and emerging hormonal and non-hormonal treatments for symptomatic uterine leiomyomas. PMID:26796059

    Background The maternal and fetal risks of uterine distension in rapidly progressive twin-twin transfusion syndrome (TTTS) in the setting of prior uterine scar are poorly characterized. Case We present the case of a 42-year-old woman, G4P1201, at 21 weeks gestation with stage-1 TTTS who developed a spontaneous posterior uterine rupture necessitating emergent laparotomy and delivery of previable fetuses, possibly due to prior uterine scar from a displaced intrauterine device. Conclusion TTTS may be a risk factor for uterine rupture, including uterine rupture in atypical anatomic locations. Prior unrecognized uterine scars, including perforations, may magnify the risk for atypical uterine rupture in the setting of excessive uterine distension. PMID:26929874

    Uterine leiomyomas (fibroids) are common benign tumors which may cause heavy or painful periods, may present as a pelvic mass and are associated with infertility. Local excision of symptomatic lesions can be difficult and hazardous, and the alternative is hysterectomy. We are investigating interstitial laser photocoagulation (ILP) as a less invasive alternative. Initial experiments were undertaken on 40 fibroids after surgical removal. One or two bare tipped, precharred fibers from a 25 W semiconductor laser (805 nm) were inserted into the center of the fibroid and treatment delivered with 2 - 10 W for 100 - 1000 sec. Specimens were subsequently sectioned perpendicular to the fiber track. Fibroids are very pale and apart from occasional charred tracts there was little evidence of thermal coagulation macroscopically or after haematoxylon and eosin staining. However, using a diaphorase stain technique we were able to demonstrate ellipsoid zones of devitalized tissue up to 20 mm across (15 mm for single fibers). These results suggest that ILP is producing gentle, uniform coagulation which could lead to resorption of treated areas. With appropriate numbers of treatment sites, this could permit minimally invasive management of clinically significant lesions. Clinical studies have commenced treating fibroids with ILP at the time of surgical excision by myomectomy or hysterectomy.

    Cotinine is a major metabolite of nicotine. This study was planned to investigate the relationship between bronchoalveolar lavage (BAL) fluid cotinine levels and serum cotinine levels in smokers and nonsmokers with various pulmonary diseases and to investigate whether these levels are affected by passive smoking. Serum and BAL fluid cotinine levels were measured in 27 patients. BAL cotinine levels were measured using a sensitive ELISA kit produced to measure cotinine in saliva. Plates were read by microuant (BioTek, USA) micro plate reader. All patient serum cotinine levels were detectable except for one nonsmoker patient. However, BAL fluid cotinine levels were measurable in only 6 patients (two of them were nonsmokers). A significant positive correlation was seen between serum and BAL fluid cotinine levels (r = 0.726; p = 0.000). Serum cotinine levels were significantly higher in present smokers than non-smokers (21.0 +/- 16.01; 5.35 +/- 7.65; p = 0.004). However, there were no significant differences in BAL fluid cotinine levels between smokers and nonsmokers. Passive smoking can increase nicotine metabolites in serum and other body fluids, including BAL fluid. Since BAL fluid and serum cotinine levels were well correlated, there is no need to use invasive procedures, such as bronchoscopy and expensive, time consuming BAL fluid analyses. Serum cotinine levels can give a rough idea of smoking status. BAL fluid cotinine meaurements should be done for only scientific reasons. PMID:21073047

    We have investigated the ability of cells obtained from both normal and immune mice by bronchoalveolar lavage (BACs) to kill Schistosoma mansoni larvae in vitro. In cultures with mechanically derived schistosomules, high levels of larvicidal activity were displayed by BACs from both normal and irradiated cercaria-immunized C57BL/6 mice. Based on effector-to-target-cell ratios, BAC-mediated killing was two- to threefold more efficient than killing mediated by macrophage-rich cell populations obtained from the peritoneal cavity. BACs from normal A/J mice were essentially as larvicidal as normal C57BL/6 cells. However, BACs from a strain of mouse (P/J) with a known macrophage defect possessed negligible larvicidal activity. Macrophages made up 85 to 95% of BACs from all three strains tested. In contrast to cells of the IC-21 macrophage cell line, B6 BACs did not show enhanced killing activity when preincubated with lymphokine-containing supernatants. Lung schistosomules harvested 10 days after cercarial penetration were refractory to BAC-mediated killing. PMID:2254018

    Background Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous disease with a significant public health burden. Currently there is no biomarker that identifies those at risk of developing COPD, progression of disease or disease phenotypes. We performed metabolomic profiling of bronchoalveolar lavage fluid (BALF) from COPD patients to determine if metabolites correlated with clinical measurements such as lung function, functional status and degree of emphysema. Methods Metabolomic components of BALF from 59 subjects with COPD and 20 healthy controls were separated by reversed-phase UPLC and analyzed by ESI-ToF mass spectrometry. We used univariate analysis and multiple regression models to investigate associations between metabolomic features and various clinical variables, such as lung function, functional status as measured by the St. George Respiratory Quotient Score and emphysema as measured by the CT density mask score. Results We identified over 3900 features by mass spectrometry, many consistent with peptides. Subjects with severe COPD had increased concentration of peptides compared to controls (p < 9.526e-05). The peptide concentration correlated with spirometry, specifically pulmonary function tests associated with airflow obstruction. There was no correlation with CT density, i.e. emphysema, or functional status. Conclusions Metabolomic profiling of BALF in COPD patients demonstrated a significant increase in peptides compared to healthy controls that associated strongly to lung function, but not emphysema or functional status.

    We obtained insight into normal lung function by proteome analysis of bronchoalveolar lavage fluid (BALF) from six normal human subjects using a “Lyse-N-Go’ shotgun proteomic protocol. Intra-sample variation was calculated using three different label-free methods, (i) protein sequence coverage; (ii) peptide spectral counts and (iii) peptide single-ion current areas (PICA), which generates protein expression data by summation of the area under the curve for a given peptide single-ion current trace and then adding values for all peptides from that same parent protein. PICA gave the least intra-subject variability and was used to calculate differences in protein expression between the six subjects. We observed an average threefold inter-sample variability, which affects analysis of changes in protein expression that occur in different diseases. We detected 167 unique proteins with >100 proteins detected in each of the six individual BAL samples, 42 of which were common to all six subjects. Gene ontology analysis demonstrated enrichment of several biological processes in the lung, reflecting its expected role in gas exchange and host defense as an immune organ. The same biological processes were enriched compared to either plasma or total genome proteome, suggesting an active enrichment of plasma proteins in the lung rather than passive capillary leak.

    Objective: To explore the method of diagnosis for uterine septum and the clinical effect of hysteroscopic transcervical resection of the septum. Methods: One-hundred ninety cases of patients with uterine septum who were diagnosed and treated at our hospital during 2007–2011 were selected, and their general information, perioperative status, postoperative recovery treatment, and postoperative pregnancy rates were statistically analyzed. Results: All 190 patients were cured with one surgery, with an average hysteroscopic operating time of 22.60 ± 10.67 minutes and intraoperative blood loss of 15.74 ± 9.64 mL. There were no complications such as uterine perforation, water intoxication, infection, or heavy bleeding. Among the 115 patients that we followed up, 86 became pregnant and delivered infants, 81 of which were born at term and 5 that were born premature. Conclusion: The combination of hysteroscopy and laparoscopy is still the most reliable method for the diagnosis of uterine septum. With a shorter operative time, less blood loss, a significantly increased postoperative pregnancy rate and live birth rate, and a significantly lower spontaneous abortion rate, transcervical resection of the septum was the preferred method for the treatment of uterine septum, and surgical instruments and skills were critical to the prognosis of uterine septum.

    Background Recent studies have definitively determined that Flow Cytometry (FC) is significantly more sensitive than cytomorphology (CM) in detection of hematolymphoid neoplasms (HLN). However, its utility in paucicellular bronchoalveolar lavage (BAL) specimens has not been established. Methods FC was performed on BAL specimens submitted from 44 patients with a prior diagnosis of HLN. Panels chosen were based upon cellularity of specimen and patient history. FC results were compared with concurrent CM evaluations. Results All 44 BALs were deemed satisfactory for FC and yielded informative results that assisted in diagnosis. Diagnoses included 22/44 B-cell neoplasms, 16/44 T-cell neoplasms, 4/44 myeloid neoplasms, and 2/44 plasma cell neoplasms. Overall concordance was demonstrated between FC and CM in 77% (34/44) of cases. In 9/44 cases (20%), one technique (FC or CM) clearly detected malignant cells when the other did not. FC was more sensitive than CM in detecting a HLN in 8/9 discordant cases. In only one case (1/44, 2%) were malignant HLN cells suspected by CM, but not identified by FC (1/44, 2%). Conclusion We demonstrate, in the largest series published to date, that FC can be performed on BAL specimens. FC is indicated in evaluation of BAL for HLN and improves sensitivity of detection of HLN over CM alone. An integrated FC and CM approach is superior to either technique alone in diagnostic evaluation of BAL. PMID:22837143

    This study was initiated to investigate the significance of uterine cell death and proliferation during the estrous cycle and early pregnancy and their correlation with sex steroids in hamsters where blastocyst implantation occurs in only progesterone-primed uteri. The results obtained in hamsters were also compared with mice where blastocyst implantation occurs in progesterone-primed uteri if estrogen is provided. Apoptotic cells in the uterus were detected by using terminal deoxynucleotide transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) technique. Uterine cell proliferation was determined by 5-bromo-2′-deoxyuridine labeling followed by immunohistochemistry and methyl-tritiated [3H]thymidine labeling. Active caspase-3, an executor protein of cell death, expression was assayed by immunohistochemistry/immunofluorescence. Our results demonstrate that epithelial proliferation on the second day after mating marks the initiation of pregnancy-related uterine changes in both species despite their differences in hormonal requirements. Hamsters and mice showed subtle differences in uterine proliferative and apoptotic patterns during early pregnancy and in response to steroids. There existed almost a direct correlation between apoptosis and caspase-3 expression, suggesting uterine cell death mostly involves the caspase pathway. Consistent with these findings, we showed, for the first time, that execution of uterine epithelial cell apoptosis by caspase-3 is important for blastocyst implantation because a caspsase-3 inhibitor N-acetyl-DEVD-CHO when instilled inside the uterine lumen on d 3 of pregnancy inhibits implantation in hamsters and mice. The overall results indicate that uterine cell apoptosis and proliferation patterns are highly ordered cell-specific phenomena that play an important role in maintaining the sexual cycle and pregnancy-associated uterine changes.

    Current data on uterus allotransplantation research has been reviewed and summarized. Over the past 15 years, progress in uterus transplantation research has increased dramatically. As a consequence, the first pregnancy and delivery following uterus allotransplantation in rats have been reported. The technique has been better defined. Although clinical pregnancy and delivery following uterus allotransplantation has been reported in humans, there are still many questions to be answered before clinical application. Gestational surrogacy still remains an important option for being a genetic parent in selected cases with uterine factor infertility. PMID:25788850

    As more complex cases and larger uterine specimens are able to be managed with minimally invasive surgery, the limitations of tissue retrieval with these methods are of increasing concern. Risks of morcellator-related injury, tissue dissemination, or fragmentation must be weighed against increased morbidity of abdominal approach to hysterectomy. In an effort to mitigate the risks of tissue morcellation, containment system use must be considered when fragmenting a specimen, either with power morcellation or a manual technique via the vagina or minilaparotomy.

    2012-01-01

    During pregnancy the mammalian uterine circulation undergoes significant expansive remodelling necessary for normal pregnancy outcome. The underlying mechanisms are poorly defined. The goal of this study was to test the hypothesis that myometrial stretch actively stimulates uterine vascular remodelling by developing a new surgical approach to induce unilateral uterine distension in non-pregnant rats. Three weeks after surgery, which consisted of an infusion of medical-grade silicone into the uterine lumen, main and mesometrial uterine artery and vein length, diameter and distensibility were recorded. Radial artery diameter, distensibility and vascular smooth muscle mitotic rate (Ki67 staining) were also measured. Unilateral uterine distension resulted in significant increases in the length of main uterine artery and vein and mesometrial segments but had no effect on vessel diameter or distensibility. In contrast, there were significant increases in the diameter of the radial arteries associated with the distended uterus. These changes were accompanied by reduced arterial distensibility and increased vascular muscle hyperplasia. In summary, this is the first report to show that myometrial stretch is a sufficient stimulus to induce significant remodelling of uterine vessels in non-pregnant rats. Moreover, the results indicate differential regulation of these growth processes as a function of vessel size and type. PMID:22781934

    Although a close connection between uterine regeneration and successful pregnancy in both humans and mice has been consistently observed, its molecular basis remains unclear. We here established a mouse model of decellularized uterine matrix (DUM) transplantation. Resected mouse uteri were processed with SDS to make DUMs without any intact cells. DUMs were transplanted into the mouse uteri with artificially induced defects, and all the uterine layers were recovered at the DUM transplantation sites within a month. In the regenerated uteri, normal hormone responsiveness in early pregnancy was observed, suggesting the regeneration of functional uteri. Uterine epithelial cells rapidly migrated and formed a normal uterine epithelial layer within a week, indicating a robust epithelial-regenerating capacity. Stromal and myometrial regeneration occurred following epithelial regeneration. In ovariectomized mice, uterine regeneration of the DUM transplantation was similarly observed, suggesting that ovarian hormones are not essential for this regeneration process. Importantly, the regenerating epithelium around the DUM demonstrated heightened STAT3 phosphorylation and cell proliferation, which was suppressed in uteri of Stat3 conditional knockout mice. These data suggest a key role of STAT3 in the initial step of the uterine regeneration process. The DUM transplantation model is a powerful tool for uterine regeneration research. PMID:27358915

    Objective An acquired uterine arteriovenous malformation (AVM) is a rare cause of vaginal bleeding and, although hysterectomy is the definitive therapy, transcatheter embolization (TCE) provides an alternative treatment option. This systematic review presents the indications, technique, and outcomes for transcatheter treatment of the acquired uterine AVMs. Study Design Literature databases were searched from 2003 to 2013 for eligible clinical studies, including the patient characteristics, procedural indication, results, complications, as well as descriptions on laterality and embolic agents utilized. Results A total of 40 studies were included comprising of 54 patients (average age of 33.4 years). TCE had a primary success rate with symptomatic control of 61% (31 patients) and secondary success rate of 91% after repeated embolization. When combined with medical therapy, symptom resolution was noted in 48 (85%) patients without more invasive surgical procedures. Conclusion Low-level evidence supports the role of TCE, including in the event of persistent bleeding following initial embolization, for the treatment of acquired uterine AVMs. The variety of embolic agents and laterality of approach delineate the importance of refining procedural protocols in the treatment of the acquired uterine AVM. Condensation A review on the management of patients with acquired uterine AVMs. PMID:26929872

    Doppler ultrasonography is a noninvasive technique which enables us to follow the physiologic and physiopathologic changes in blood flow in tissues. It is becoming an essential tool in veterinary medicine, especially in theriogenology. Twenty-seven Arabian mares were grouped by age ('young', 3-10 y, n=15; 'old', 19-23 y, n=12). The uterine arteries of the mares were examined using Doppler ultrasonography when an ovarian follicle ≥35mm was visible (Day -1). After these measurements, human chorionic gonadotropin (hCG; 2500IU) was administered to 14 mares selected randomly. One day later (Day 0) Doppler ultrasonography was repeated and then the dominant follicles were aspirated to collect follicular fluid in all groups. On the next day (Day +1), Doppler indices of the uterine artery blood flow were measured again. Blood samples were also collected just prior to ultrasonography, for measuring serum estradiol and progesterone levels. We found that preovulatory hCG administration had no significant effects on uterine artery blood flow indices, or serum or follicular fluid estradiol concentrations. The uterine artery resistance index might decrease in young mares after ovulation, possibly because of increased uterine perfusion. PMID:25465361

    Purpose: To evaluate the clinical outcome for uterine adenomyosis with or without uterine leiomyomata 40 months after uterine artery embolization (UAE). Methods: Forty women aged 39-56 years (median 46 years) with symptomatic uterine adenomyosis and magnetic resonance imaging findings of uterine adenomyosis with or without combined uterine leiomyomata underwent UAE. Self-perceived changes in clinical symptoms were assessed, and residual symptom severity and health-related quality of life (HRQOL) after UAE were evaluated. Clinical failure was defined as no symptomatic improvement or second invasive therapy after UAE. Results were stratified by the extent of uterine adenomyosis at baseline magnetic resonance imaging. Results: Patients were followed for a median of 40 months (range 5-102 months). UAE led to symptomatic control after UAE in 29 (72.5%) of 40 patients while 11 women underwent hysterectomy (n = 10) or dilatation and curettage (n = 1) for therapy failure. No significant difference between women with pure uterine adenoymosis and women with uterine adenomyosis combined with uterine leiomyomata was observed. Best results were shown for UAE in uterine adenomyosis with uterine leiomyomata predominance as opposed to predominant uterine adenomyosis with minor fibroid disease (clinical failure 0% vs. 31.5%, P = 0.058). Throughout the study group, HRQOL score values increased and symptom severity scores decreased after UAE. Least improvement was noted for women with pure adenomyosis. Conclusions: UAE is clinically effective in the long term in most women with uterine adenomyosis. Symptomatic control and HRQOL were highest in patients with combined disease of uterine adenomyosis but leiomyomata predominance.

    We have studied in this work 30 human uterine arteries which were taken from hysterectomy specimens where the indication for the hysterectomy was obstetrical or gynaecological. The arteries were prepared in strips using furchgott and Bhadrakom's technique that they developed for the isolated aorta of the rabbit so that the authors could study the response to oxytocin on the isolated human uterine artery. When CIK was added to the preparation in which the arteries were, oxytocin had an antagonistic effect which was dose-dependent. The same effect was noted when Cl2Ba was added. PMID:7175111

    Adenomyosis is a common gynecological disorder characterized by the presence of endometrial glands and stroma deep within the myometrium associated with myometrial hypertrophy and hyperplasia. Focal uterine infarction after IVF-ET in a patient with adenomyosis following biochemical pregnancy has not been previously reported, although it occurs after uterine artery embolization in order to control symptoms caused by fibroids or adenomyosis. We report a case of a nulliparous woman who had uterine adenomyosis presenting with fever, pelvic pain and biochemical abortion after undergoing an IVF-ET procedure and the detection of a slightly elevated serum hCG. Focal uterine infarction was suspected after a pelvic magnetic resonance imaging demonstrated preserved myometrium between the endometrial cavity and inner margin of the necrotic myometrium. This case demonstrates that focal uterine infarction should be considered in the differential diagnosis of acute abdominal pain, vaginal bleeding and infectious signs in women experiencing biochemical abortion after an IVF-ET procedure.

    Uterine sarcomas account for 3-7% of all uterine cancers. Because of their rarity, unknown etiology, and highly divergent genetic aberration, there is a lack of consensus on risk factors for occurrence and predictive poor outcomes as well as optimal therapeutic choices. Tumor types according to the World Health Organization classification include leiomyosarcoma, endometrial stroma sarcoma, and undifferentiated sarcoma. Staging is done using the 2014 Federation International Gynecology and Obstetrics and 2010 American Joint Committee on Cancer tumor, lymph node, and metastases systems. Tumor grade can be classified based on the French Federation of Cancer Centers Sarcoma Group system or the Broder's system that incorporates tumor differentiation, mitotic count, and tumor necrosis. This review is a series of articles discussing uterine sarcoma, and this is Part I, which focuses on one of the subtypes of uterine sarcomas-uterine leiomyosarcoma. The clinical characteristics, diagnosis, outcome, and recent advances are summarized in this article. PMID:27590365

    Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity. PMID:25692425

    Nowadays endoscopic techniques are one of the basic diagnostic and operative methods in gynecology. Laparoscopy and hysteroscopy are the most popular of them. Office hysteroscopy is a modern diagnostic and therapeutic method feasible in an outpatient room because no necessity of anesthesia. It is the first-line procedure in the infertility diagnosis and treatment of uterine pathology such as polyps, submucosal fibroids and adhesions. Limitation of this method is the cervical canal atresia. Contraindications to it are: pregnancy, uterine bleeding, active inflammation of pelvic organs, cervical cancer. Due to the high sensitivity and specificity, simplicity of execution and no need for patient hospitalization, office hysteroscopy becomes important diagnostic and therapeutic procedure in uterine pathologies.

    Magnetic Resonance-guided focused Ultrasound Surgery (MRgFUS) is gaining popularity as an alternative to medical and surgical interventions in the management of symptomatic uterine fibroids. Studies have shown that it is an effective non-invasive treatment with minimal associated risks as compared to myomectomy and hysterectomy. MRgFUS can be offered to a majority of patients suffering from symptomatic uterine fibroids. It has been suggested that the use of broader inclusion criteria as well as the mitigation techniques makes it possible to offer MRgFUS to a much larger subset of patients than previously believed. This paper will describe how MRgFUS treatment for uterine fibroids is performed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia. PMID:21611036

    Uterine vascular elastosis in mares is characterized by degeneration of uterine vasculature through thickening of the elastin layers. Factors commonly associated with this degeneration include age, parity, and chronic uterine endometritis. Affected mares have also been shown to exhibit decreases in uterine blood flow and perfusion of the uterus. Due to the increased thickness of the elastin layers, we hypothesize that vasodilatation of the uterine vasculature is also impaired. To test the functionality of these vessels, we evaluated the vasodilatory effects of estradiol on the uterine vascular bed in mares with normal vasculature and mares with severe elastosis. Both groups were tested in estrus and diestrus. Fluorescent microspheres were used to determine basal blood perfusion, followed by the intravenous administration of 1.0 μg/kg of 17β-estradiol. After 90 min, perfusion was measured once again to determine the vascular response to estradiol. Control mares in estrus displayed a significant increase in total uterine blood flow after the administration of estradiol when compared to baseline levels. No other group had a significant increase in total blood flow and perfusion after estradiol administration. The administration of estradiol in control mares induced regional increases in perfusion in the uterine horns and uterine body during estrus and only in the uterine horns during diestrus. Mares affected by elastosis exhibited no regional differences in perfusion levels post-estradiol administration. The difference in the vasodilatory response induced by estradiol between reproductively healthy mares and mares affected with elastosis indicates that the functionality of the affected vessels is compromised.

    Objective To investigate the impact of fibroids on the blood flow of the uterine and subendometrial arteries and in vitro fertilization (IVF) outcomes. Methods In this study, we analyzed 86 IVF/intracytoplasmic sperm injection (ICSI) cycles in which a gonadotropin-releasing hormone antagonist protocol was used for controlled ovarian stimulation between January 2008 and March 2009. The subjects comprised 86 infertile women with (fibroid group, n=43) or without (control group, n=43) uterine fibroids. Results Patient characteristics were similar between the fibroid and control groups. The IVF/ICSI outcomes in patients with fibroids were similar to those of patients in the control group. The resistance index (RI) and pulsatile index (PI) of the uterine and subendometrial arteries on the day of embryo transfer were also comparable between the two groups. IVF outcomes and uterine hemodynamics in patients with multiple (≥2) fibroids were similar to those of patients with a single fibroid. However, clinical pregnancy and implantation rates were significantly lower in patients with fibroids who experienced uterine cavity distortion than in patients with fibroids who had a normal uterine cavity (both p<0.05). The RI and PI of the subendometrial artery were significantly higher on the day of embryo transfer in patients with fibroids who experienced uterine cavity distortion than in patients with fibroids who had a normal uterine cavity (both p<0.05). Conclusion Fibroids which distorting the uterine cavity might impair the subendometrial artery blood flow clinical pregnancy rate and embryo implantation rate in infertile patients undergoing IVF. Otherwise, IVF outcomes were not influenced by the presence of uterine fibroids. PMID:26816875

    N-acetylcysteine (600 mg/day) was given to patients by mouth for five days before bronchoscopy and bronchoalveolar lavage to determine whether N-acetylcysteine could increase the concentrations of the antioxidant reduced glutathione in plasma and bronchoalveolar lavage fluid. Bronchoalveolar lavage was performed 1-3 hours (group 2, n = 9) and 16-20 hours (group 3, n = 10) after the last dose of N-acetylcysteine and the values were compared with those in a control group receiving no N-acetylcysteine (group 1, n = 8). N-acetylcysteine was not detected in plasma or lavage fluid. Plasma concentrations of cysteine, the main metabolite of N-acetylcysteine and a precursor of reduced glutathione, were greater in the groups receiving treatment (groups 2 and 3) than in group 1. Cysteine concentrations in lavage fluid were similar in the three groups. Concentrations of reduced glutathione were greater in both plasma and lavage fluid in group 2 than in group 1. These data suggest that N-acetylcysteine given by mouth is rapidly deacetylated to cysteine, with resulting increases in the concentrations of cysteine in plasma and of reduced glutathione in plasma and the airways, which thus temporarily increase the antioxidant capacity of the lung.

    Objective: To evaluate short-term outcomes of a new treatment for perforated diverticulitis with purulent peritonitis in a randomized controlled trial. Background: Perforated diverticulitis with purulent peritonitis (Hinchey III) has traditionally been treated with surgery including colon resection and stoma (Hartmann procedure) with considerable postoperative morbidity and mortality. Laparoscopic lavage has been suggested as a less invasive surgical treatment. Methods: Laparoscopic lavage was compared with colon resection and stoma in a randomized controlled multicenter trial, DILALA (ISRCTN82208287). Initial diagnostic laparoscopy showing Hinchey III was followed by randomization. Clinical data was collected up to 12 weeks postoperatively. Results: Eighty-three patients were randomized, out of whom 39 patients in laparoscopic lavage and 36 patients in the Hartmann procedure groups were available for analysis. Morbidity and mortality after laparoscopic lavage did not differ when compared with the Hartmann procedure. Laparoscopic lavage resulted in shorter operating time, shorter time in the recovery unit, and shorter hospital stay. Conclusions: In this trial, laparoscopic lavage as treatment for patients with perforated diverticulitis Hinchey III was feasible and safe in the short-term. PMID:25489672

    Aim For patients receiving endoscopic submucosal dissection (ESD), there is urgent need pertaining to the prevention of postoperative bleeding. We conducted a retrospective propensity score-matched study that evaluated whether pre-ESD gastric lavage prevents postoperative bleeding after ESD for gastric neoplasms. Methods From September 2002 to October 2015, the 760 consecutive patients receiving ESD for gastric neoplasm were enrolled and data regarding them were retrospectively analyzed. All patients received conventional preventive treatment against delayed bleeding after ESD, including the administration of proton pump inhibitor and preventive coagulation of visible vessels, at the end of the ESD procedure. Results Pre-ESD risk factors for postoperative bleeding included tumor size and no gastric lavage. Using multivariate analysis tumor size >2.0 cm (HR 2.90, 95% CI 1.65–5.10, p = 0.0002) and no gastric lavage (HR 3.20, 95% CI 1.13–9.11, p = 0.029) were found to be independent risk factors. Next, we evaluated the effect of gastric lavage on the prevention of post-ESD bleeding using a propensity score-matching method. A total of 284 subjects (142 per group) were selected. Adjusted odds ratio of gastric lavage for post-ESD bleeding was 0.25 (95% CI 0.071–0.886, p = 0.032). Conclusion Pretreatment gastric lavage reduced postoperative bleeding in patients receiving ESD for gastric neoplasm. PMID:26871449

    Neutrophils (PMNs) obtained by nasal lavage were counted to determine if ozone, an oxidant air pollutant, induces an acute inflammatory response in the upper respiratory tract (URT) of humans. Background data were obtained by the nasal lavages from 200 nonexperimentally exposed subjects. Then, using a known inflammatory agent for the URT, rhinovirus-type 39, the induction, peak, and resolution of an acute inflammatory response was shown to be documented by the nasal lavage PMN counts. To determined if ozone induces this response, 41 subjects were exposed to either filtered air or 0.5 ppm ozone for 4 hr, on 2 consecutive days. Nasal lavages were taken pre-, immediately post each exposure, and 22 hr following the last exposure. Lavage PMN counts increased significantly (p = .005) in the ozone-exposed group, with 3.5-, 6.5-, and 3.9-fold increases over the air-exposed group at the post 1, pre 2, and post 2 time points, respectively. Ozone induces an inflammatory response in the URT of humans, and nasal lavage PMN counts are useful to assay the inflammatory properties of air pollutants.

    Endometrial cancer typically presents at an early stage when surgery alone, with or without radiotherapy, is often curative. However, in women who present with advanced disease or who develop disease recurrence, long-term prognosis is poor. While surgical cytoreduction remains the mainstay of initial therapy, over the last several decades, the roles of cytotoxic chemotherapy, radiotherapy, and hormonal therapy have been evaluated in both the adjuvant and recurrent setting in an attempt to improve long-term survival while also minimizing associated toxicities. Unfortunately, response rates remain poor and survival is limited in these settings. More recently, with the introduction of personalized cancer treatment, several biologic agents have been developed that target specific pathways critical to tumor initiation and growth. Molecular studies have found that many endometrial cancers are driven by some of these tumorigenic pathways, which has led to early clinical studies evaluating the role of these targeted agents in patients with advanced or recurrent endometrial cancer. This review describes existing treatment options for patients with early and advanced endometrioid endometrial cancer, as well as for patients with uterine serous cancers. Furthermore, this review examines the growing body of literature involving targeted biologic agents as treatment for patients with advanced or recurrent endometrial cancer. PMID:23271352

    Bronchoalveolar lavage (BAL) is a pulmonary sampling technique for characterization of drug concentrations in epithelial lining fluid and alveolar cells. Two hypothetical drugs with different pulmonary distribution rates (fast and slow) were considered. An optimized BAL sampling design was generated assuming no previous information regarding the pulmonary distribution (rate and extent) and with a maximum of two samples per subject. Simulations were performed to evaluate the impact of the number of samples per subject (1 or 2) and the sample size on the relative bias and relative root mean square error of the parameter estimates (rate and extent of pulmonary distribution). The optimized BAL sampling design depends on a characterized plasma concentration time profile, a population plasma pharmacokinetic model, the limit of quantification (LOQ) of the BAL method and involves only two BAL sample time points, one early and one late. The early sample should be taken as early as possible, where concentrations in the BAL fluid ≥ LOQ. The second sample should be taken at a time point in the declining part of the plasma curve, where the plasma concentration is equivalent to the plasma concentration in the early sample. Using a previously described general pulmonary distribution model linked to a plasma population pharmacokinetic model, simulated data using the final BAL sampling design enabled characterization of both the rate and extent of pulmonary distribution. The optimized BAL sampling design enables characterization of both the rate and extent of the pulmonary distribution for both fast and slowly equilibrating drugs. PMID:26316105

    Background. Uterine inversion is a rare, but life threatening, obstetrical emergency which occurs when the uterine fundus collapses into the endometrial cavity. Various conservative and surgical therapies have been outlined in the literature for the management of uterine inversions. Case. We present a case of a chronic, recurrent uterine inversion, which was diagnosed following spontaneous vaginal delivery and recurred seven weeks later. The uterine inversion was likely due to a leiomyoma. This late-presenting, chronic, recurring uterine inversion was treated with a vaginal hysterectomy. Conclusion. Uterine inversions can occur in both acute and chronic phases. Persistent vaginal bleeding with the appearance of a prolapsing fibroid should prompt further investigation for uterine inversion and may require surgical therapy. A vaginal hysterectomy may be an appropriate management option in select populations and may be considered in women who do not desire to maintain reproductive function. PMID:25379314

    There is a dialogue between the developing conceptus (embryo-fetus and associated placental membranes) and maternal uterus which must be established during the peri-implantation period for pregnancy recognition signaling, implantation, regulation of gene expression by uterine epithelial and stromal cells, placentation and exchange of nutrients and gases. The uterus provide a microenvironment in which molecules secreted by uterine epithelia or transported into the uterine lumen represent histotroph required for growth and development of the conceptus and receptivity of the uterus to implantation. Pregnancy recognition signaling mechanisms sustain the functional lifespan of the corpora lutea (CL) which produce progesterone, the hormone of pregnancy essential for uterine functions that support implantation and placentation required for a successful outcome of pregnancy. It is within the peri-implantation period that most embryonic deaths occur due to deficiencies attributed to uterine functions or failure of the conceptus to develop appropriately, signal pregnancy recognition and/or undergo implantation and placentation. With proper placentation, the fetal fluids and fetal membranes each have unique functions to ensure hematotrophic and histotrophic nutrition in support of growth and development of the fetus. The endocrine status of the pregnant female and her nutritional status are critical for successful establishment and maintenance of pregnancy. This review addresses the complexity of key mechanisms that are characteristic of successful reproduction in sheep and pigs and gaps in knowledge that must be the subject of research in order to enhance fertility and reproductive health of livestock species.

    Objective To determine whether performing uterine artery embolization (UAE) immediately before laparoscopic myomectomy can facilitate a minimally invasive surgical approach for larger uterine fibroids. Methods In a retrospective case–control study, laparoscopic myomectomy with and without preoperative UAE was examined. Data were analyzed from 26 laparoscopic myomectomies performed by a single surgeon at Northwestern University Feinberg School of Medicine between 2004 and 2010. Controls were matched for age, calendar year, surgeon, and number of fibroids removed. Surgical outcomes included preoperative clinical uterine size, operative time, operative blood loss, and postoperative myoma specimen weight. Data were analyzed via 2-tailed Student t test. Results Twelve women underwent laparoscopic myomectomy within 169±16 minutes (mean±SEM) of preoperative UAE. Fourteen control patients underwent laparoscopic myomectomy alone. The UAE group had a greater mean preoperative clinical uterine size (19.7 versus 12.4 weeks, P<0.001) and a greater mean myoma specimen weight measured postoperatively (595.3 versus 153.6 grams, P<0.05). There were no significant differences in operative time or blood loss, and there were no intra-operative complications. Conclusion UAE performed immediately before laparoscopic myomectomy facilitated minimally invasive surgery for larger uteri and larger uterine myomas, with no differences in operative time or blood loss.

    Hemoperitoneum during pregnancy is a rare but potentially lethal clinical condition. Improvements in antenatal and intrapartum care, especially in surgical and anesthetic techniques, have reduced maternal mortality; perinatal mortality remains very high (31%). Treatment is based on the systemic correction of hypovolemia and immediate surgery via laparotomy or laparoscopy in cases in the first trimester of pregnancy for hemostatic purposes. Sometimes, hysterectomy is needed. A 35-year-old Asiatic primigravid woman at 37 weeks' gestation with otherwise uneventful pregnancy came to the hospital referring abrupt-onset lumbar and abdominal pain. A bleeding uterine superficial varicocele of about 7 cm was found on the left uterine horn during Caesarean section. Interventional radiologic embolization of both uterine arteries was successfully performed. Posterior evolution of the patient was favorable. Percutaneous vascular embolization of the uterine arteries is an effective alternative treatment for many obstetrical and gynecological causes of bleeding. The main advantage of this technique is the low rate of serious complications and the preservation of reproductive function. To our knowledge, this is the first case of spontaneous intrapartum hemoperitoneum treated with this technique. An early diagnosis and a rapid indication of this therapeutic option are essential. Hemodynamic stability is needed to decide this conservative management. PMID:25114819

    Metastasis of uterine leiomyosarcoma to the pancreas is rare. A 46-year-old woman was diagnosed with uterine leiomyosarcoma and underwent surgery. Thereafter, recurrences in the lung and subsequently in the pancreas were diagnosed. These lesions were resected and diagnosed as metastasis of uterine leiomyosarcoma. We report a rare case of uterine leiomyosarcoma with metastasis to the lung and pancreas, both of which were resected using aggressive surgery. PMID:20851807

    To investigate the effectiveness of laparoscopic uterine artery occlusion combined with myomectomy for uterine fibroids. From August 2008 to August 2009, forty-eight women with uterine fibroids desiring to preserve their uteri underwent laparoscopic myomectomy. Among them, 18 women received laparoscopic uterine artery occlusion before uterine myomectomy while the others received laparoscopic myomectomy only. All of the 48 cases with uterine fibroids underwent laparoscopic myomectomy successfully, and no patient developed Intraoperative or postoperative complications. The average operation time was (105.6±27.6) min, and the average surgical blood loss was (87.52±18.35) ml. Blocking uterine artery before laparoscopic myomectomy is valuable and feasible for the management of women with symptomatic fibroids. Adopting this method can obtain pleasing therapeutic effect. The method can reduce blood loss thus make the surgical field clean and clear, and it can reduce the operating time and recurrence rate. It can also reduce electro-coagulation on the surgical surface and therefore cause less tissue necrosis and lower incidence of complications. PMID:24995096

    Uterine artery embolization has Level A data supporting excellent safety and efficacy in treating symptomatic uterine leiomyomata. However, there is a perception that either postprocedural pain is severe or poorly managed by the physician performing these procedures. This has led some primary care physicians to omit this procedure from the patients' options or to steer patients away from this procedure. A few simple techniques (pruning of the vascular tree and embolizing to 5–10 beat stasis) and fastidious pre-, intra-, and post-procedural management can nearly eliminate significant pain associated with embolization. Specifically, early implementation of long-acting low-dose narcotics, antiemetics and anti-inflammatory medications is critical. Finally, the use of a superior hypogastric nerve block, which takes minutes to perform and carries a very low risk, significantly reduces pain and diminishes the need for narcotics; when this technique was used in a prospective study, all patients were able to be discharged the day of the procedure. In the authors' experience, patients treated in this manner largely recover completely within 5 days and have a far less traumatic experience than patients traditionally treated with only midazolam (Versed) and fentanyl citrate (fentanyl) intraprocedurally, and narcotics and nonsteroidal antiinflammatory drugs postprocedurally.

    A fraction of cells residing in the uterine endometrium exhibit functional pluripotent potential, allowing them to be classified as adult stem cells. While the physiological relevance of this cell population is mostly conjectural at this juncture, uterine endometrial stem cells (UESC's) may underline pathogenesis of certain common gynecological disorders, such as endometriosis and adenomyosis. The ease of access and harvesting of UESC's and the diverse differentiation potential of this cell population has identified the uterine endometrium as a valuable source of autologous stem cells that can be harnessed through judicious application of principals of regenerative medicine. This mini review offers a glimpse into the journey, and an introduction to the spectrum of disorders that UESC's have the potential of impacting. PMID:26297687

    Uterine transplantation has been proposed as a possible solution to absolute uterine factor infertility untreatable by any other option. Since the first human attempt in 2000, various teams have tried to clarify which immunosuppressant would be most suitable for protecting the allogeneic uterine graft while posing a minimal risk to the fetus. Cyclosporine A (CsA) is an immunosuppressant widely used by transplant recipients. It is currently being tested as a potential immunosuppressant to be used during UTn. Its effect on the mother and fetus and its influence upon the graft during pregnancy have been of major concern. We review the role of CsA in UTn and its effect on pregnant transplant recipients and their offspring. PMID:22132302

    AIM: To evaluate short-term outcomes following intraoperative biliary lavage for hepatolithiasis. METHODS: A total of 932 patients who were admitted to the West China Medical Center of Sichuan University between January 2010 and January 2014 and underwent bile duct exploration and lithotomy were retrospectively included in our study. The patients were divided into the lavage group and the control group. Related pre-, intra-, and postoperative factors were recorded, analyzed, and compared between the two groups in order to verify the effects of biliary lavage on the short-term outcome of patients with hepatolithiasis. RESULTS: Amongst the patients who were included, 678 patients with hepatolithiasis were included in the lavage group, and the other 254 patients were enrolled in the control group. Data analyses revealed that preoperative baseline and related intraoperative variables were not significantly different. However, patients who underwent intraoperative biliary lavage had prolonged postoperative hospital stays (6.67 d vs 7.82 d, P = 0.024), higher hospitalization fees (RMB 28437.1 vs RMB 32264.2, P = 0.043), higher positive rates of bacterial cultures from blood (13.3% vs 25.8%, P = 0.001) and bile (23.6% vs 40.7%, P = 0.001) samples, and increased usage of advanced antibiotics (26.3% vs 38.2%, P = 0.001). In addition, in the lavage group, more patients had fever (> 37.5 °C, 81.4% vs 91.1%, P = 0.001) and hyperthermia (> 38.5°C,39.7% vs 54.9%, P = 0.001), and higher white blood cell counts within 7 d after the operation compared to the control group. CONCLUSION: Intraoperative biliary lavage might increase the risk of postoperative infection, while not significantly increasing gallstone removal rate. PMID:27004001

    Uterine transplantation surgery has been proposed as a treatment for permanent absolute uterine factor infertility (AUFI) in the case of loss of the uterus. Due to the complexity of the vasculature correct reanastomosis of the blood supply during transplantation surgery is a crucial step to ensure reperfusion and viability of the organ. While techniques such as fluorescent dye imaging have been proposed to visualise perfusion there is no gold standard for intraoperative visualisation of tissue oxygenation. In this paper results from a liquid crystal tuneable filter (LCTF)-based multispectral imaging (MSI) laparoscope are described. The system was used to monitor uterine oxygen saturation (SaO2) before and after transplantation. Results from surgeries on two animal models (rabbits and sheep) are presented. A feature-based registration algorithm was used to correct for misalignment induced by breathing or peristalsis in the tissues of interest prior to analysis. An absorption spectrum was calculated at each spatial pixel location using reflectance data from a reference standard, and the relative contributions from oxy- and deoxyhaemoglobin were calculated using a least squares regression algorithm with non-negativity constraints. Results acquired during animal surgeries show that cornual oxygenation changes are consistent with those observed in point measurements taken using a pulse oximeter, showing reduced SaO2 following reanastomosis. Values obtained using the MSI laparoscope were lower than those taken with the pulse oximeter, which may be due to the latter's use of the pulsatile arterial blood signal. Future work incorporating immunological test results will help to correlate SaO2 levels with surgical outcomes.

    Background In patients with advanced-stage endometrial carcinoma (eca), extended-field radiotherapy (efrt) is traditionally delivered by the 3-dimensional conformal (3d-crt) 4-field box technique. In recent years, the use of intensity-modulated radiotherapy (imrt) in gynecologic cancers has increased. We compared the delivery of efrt by the 3d-crt and contemporary imrt techniques. Methods After surgical staging and adjuvant chemotherapy in 38 eca patients, efrt was delivered by either imrt or 3d-crt. Doses to the organs at risk, side effects, and outcomes were compared between the techniques. Results Of the 38 eca patients, 33 were stage iiic, and 5 were stage ivb. In the imrt group, maximal doses to rectum, small intestine, and bladder were significantly higher, and mean dose to bladder was lower (p < 0.0001). Most acute gastrointestinal, genitourinary, and hematologic side effects were grade i or ii and were comparable between the groups. In long-term follow-up, only grade 1 cystitis at 3 months was statistically higher in the imrt patients. No grade iii or iv gastrointestinal or genitourinary toxicities were observed. No statistically significant differences in overall and disease-free survival or recurrence rates were observed between the techniques. Conclusions In advanced eca patients, imrt is a safe and effective technique for delivering efrt to the pelvis and para-aortic region, and it is comparable to the 3d-crt 4-field box technique in both side effects and efficacy. For centres in which imrt is not readily available, 3d-crt is a valid alternative. PMID:26715873

    Hysterectomy at the time of an obstetric delivery or postpartum is an uncommon time to perform one of the most common gynecologic procedures. Hysterectomy associated with pregnancy is often unplanned and undesired. Postpartum complications associated with the need for hysterectomy carry significant risks, which pose challenges for mother-infant bonding and can signify an unexpected end to fertility. The most common indication for hysterectomy is postpartum hemorrhage. Postpartum hemorrhage is caused by uterine atony, genital tract laceration, uterine rupture, invasive placentation, infection, or coagulopathy. Multidisciplinary teams improve outcomes and are capable of managing complex medical and surgical complications that occur postpartum. PMID:27521882

    Understanding the mechanisms of uterine contractions during pregnancy is especially important in predicting the onset of labor and thus in forecasting preterm deliveries. Preterm birth can cause serious health problems in newborns, as well as large financial burdens to society. Various techniques such as electromyography (EMG) and magnetomyography (MMG) have been developed to quantify uterine contractions. However, no widely accepted method to predict labor based on electromagnetic measurement is available. Therefore, developing a biophysical model of EMG and MMG could help better understand uterine contractions, interpret real measurements, and detect labor. In this work, we propose a multiscale realistic model of uterine contractions during pregnancy. At the cellular level, building on bifurcation theory, we apply generalized FitzHugh-Nagumo (FHN) equations that produces both plateau-type and bursting-type action potentials. At the tissue level, we introduce a random fiber orientation model applicable to an arbitrary uterine shape. We also develop an analytical expression for the propagation speed of transmembrane potential. At the organ level, a realistic volume conductor geometry model is provided based on magnetic resonance images of a pregnant woman. To simulate the measurements from the SQUID Array for Reproductive Assessment (SARA) device, we propose a sensor array model. Our model is able to reproduce the characteristics of action potentials. Additionally, we investigate the sensitivity of MMG to model configuration aspects such as volume geometry, fiber orientation, and pacemaker location. Our numerical results show that fiber orientation and pacemaker location are the key aspects that greatly affect the MMG as measured by the SARA device. We conclude that sphere is appropriate as an approximation of the volume geometry. The initial step towards validating the model against real MMG measurement is also presented.

    Coordinated uterine-embryonic axis formation and decidual remodeling are hallmarks of mammalian post-implantation embryo development. Embryonic-uterine orientation is determined at initial implantation and synchronized with decidual development. However, the molecular mechanisms controlling these events remain elusive despite its discovery a long time ago. In the present study, we found that uterine-specific deletion of Rbpj, the nuclear transducer of Notch signaling, resulted in abnormal embryonic-uterine orientation and decidual patterning at post-implantation stages, leading to substantial embryo loss. We further revealed that prior to embryo attachment, Rbpj confers on-time uterine lumen shape transformation via physically interacting with uterine estrogen receptor (ERα) in a Notch pathway-independent manner, which is essential for the initial establishment of embryo orientation in alignment with uterine axis. While at post-implantation stages, Rbpj directly regulates the expression of uterine matrix metalloproteinase in a Notch pathway-dependent manner, which is required for normal post-implantation decidual remodeling. These results demonstrate that uterine Rbpj is essential for normal embryo development via instructing the initial embryonic-uterine orientation and ensuring normal decidual patterning in a stage-specific manner. Our data also substantiate the concept that normal mammalian embryonic-uterine orientation requires proper guidance from developmentally controlled uterine signaling. PMID:24971735

    Objectives Magnetic resonance imaging (MRI)-guided high intensity focused ultrasound surgery (MRgFUS) is a newly emerging non-invasive technique for the treatment of uterine fibroids. The purpose of this study is to review the clinical impact of MRgFUS. Methods This study examined 157 patients. The high intensity focused ultrasound (HIFU) utilized in this study was Philips Achieva 1.5 Tesla MR (Philips Healthcare, Best, the Netherlands) and Sonalleve HIFU system. The patients were followed in post-operative Month 1, Month 3, and Month 6 to investigate any change. Then, these were further classified according to the use of uterine stimulant (oxytocin) in parallel, Funaki Type of uterine fibroid, HIFU intensity, and non-perfused volume (NPV) ratio. Results When the uterine stimulant was utilized, the HIFU intensity was measured at significantly lower levels, compared with the group not using uterine stimulant, and treatment duration was significantly. The NPV ratio was found significantly higher in the group using uterine stimulant. Concerning the correlation between Funaki Type of uterine fibroid and average sonication power, it was found that the closer to Type I, the lower the sonication power, the shorter the treatment duration, and the higher the NPV ratio significantly. Conclusions In this study, it was found that the lower the Funaki Types of uterine fibroids, and the higher the NPV ratio immediately after the operation, the larger the uterine fibroid volume decrease and SSS change were. Also, if uterine stimulant was used in parallel in treatment, treatment duration and HIFU intensity could become shorter and lower. PMID:27617244

    Background: Food hypersensitivity is commonly suspected, but seldom verified. Patients with subjective food hypersensitivity suffer from both intestinal and extraintestinal health complaints. Abnormalities of the enterochromaffin cells may play a role in the pathogenesis. The aim of this study was to investigate enterochromaffin cell function in patients with subjective food hypersensitivity by measuring serum chromogranin A (CgA) and 5-hydroxytryptamine (5-HT, serotonin) in gut lavage fluid. Methods: Sixty-nine patients with subjective food hypersensitivity were examined. Twenty-three patients with inflammatory bowel disease and 35 healthy volunteers were included as comparison groups. CgA was measured in serum by enzyme-linked immunosorbent assay. Gut lavage fluid was obtained by administering 2 L of polyethylene glycol solution intraduodenally. The first clear fluid passed per rectum was collected and 5-HT was analyzed by liquid chromatography tandem mass spectrometry. Results: Serum levels of CgA were significantly lower in patients with subjective food hypersensitivity than in healthy controls (P = 0.04). No differences were found in 5-HT levels in gut lavage fluid between patients with subjective food hypersensitivity and the control groups. There was no correlation between serum CgA and gut lavage 5-HT. Conclusion: Decreased blood levels of CgA suggest neuroendocrine alterations in patients with subjective food hypersensitivity. However, 5-HT levels in gut lavage fluid were normal. PMID:21887108

    OBJECTIVE: To investigate the role of pleural lavage cytology (PLC) in resection for primary lung carcinoma. SUMMARY BACKGROUND DATA: The prognostic significance of PLC before manipulation is still controversial. METHODS: Cytology of pleural lavage immediately after thoracotomy but before any manipulation of the lung was examined in 500 consecutive patients with lung cancer with no pleural effusion who underwent pulmonary resections. Eighteen patients who already had pleural dissemination were excluded from this study. RESULTS: Eighteen of 482 patients (3.7%) had positive cytologic findings. The positivity of PLC was significantly correlated with histology, extension of tumor to pleura, and presence of lymphatic permeation or vascular involvement by tumor. Positive lavage findings were seen only in adenocarcinoma. Because 6.3% of the patients with adenocarcinoma had positive cytologic findings, it is vital to perform PLC before curative resections for lung cancer, especially adenocarcinoma. The 5-year survival rates of the patients having negative and positive lavage findings were 52.9% and 14.6%, respectively. The prognosis of the patients with positive lavage findings was as poor as that of the patients with stage IIIB disease and that of the patients with malignant effusion. CONCLUSIONS: Positive findings on PLC indicate exfoliation of cancer cells into the pleural cavity, which is an essential prognostic factor. In addition, we should regard positive cytologic findings as a subclinical malignant pleural effusion that is pathologic stage T4. PMID:10203093

    Pulmonary alveolar proteinosis is a rare idiopathic lung disease characterized by the accumulation of lipoproteinaceous material within the alveoli, which impairs gas transfer and decreases the ventilation/perfusion ratio, and can lead to respiratory failure. Whole lung lavage is the most effective therapy for pulmonary alveolar proteinosis, but may not be tolerated by patients with severe respiratory failure. Extracorporeal membrane oxygenation support is advocated for such patients to ensure appropriate oxygenation during lung lavage. We report a case of a 39-year-old patient with pulmonary alveolar proteinosis and severe life-threatening respiratory failure, with an oxygen index of 51 when under mechanical ventilation. The patient was successfully treated with bilateral whole lung lavage without extracorporeal oxygenation. The results suggest that there is improved ventilation and perfusion matching when one lung is ventilated while the other is lavaged, may be the mechanism of which severe respiratory failure patient due to pulmonary alveolar proteinosis can complete whole lung lavage under one lung ventilation.

Whole lung lavage is the most effective therapy for pulmonary alveolar proteinosis, but may not be tolerated by patients with severe respiratory failure. Extracorporeal membrane oxygenation support is advocated for such patients to ensure appropriate oxygenation during lung lavage. We report a case of a 39-year-old patient with pulmonary alveolar proteinosis and severe life-threatening respiratory failure, with an oxygen index of 51 when under mechanical ventilation. The patient was successfully treated with bilateral whole lung lavage without extracorporeal oxygenation. The results suggest that there is improved ventilation and perfusion matching when one lung is ventilated while the other is lavaged, may be the mechanism of which severe respiratory failure patient due to pulmonary alveolar proteinosis can complete whole lung lavage under one lung ventilation.

    Purpose: We have observed significant rates of uterine artery patency after uterine artery embolization (UAE) with nonspherical polyvinyl alcohol (nsPVA) on 6 month follow-up MR scanning. The study aim was to quantitatively assess uterine artery patency after UAE with nsPVA and to assess the effect of continued uterine artery patency on outcomes. Methods: A single centre, retrospective study of 50 patients undergoing bilateral UAE for uterine leiomyomata was undertaken. Pelvic MRI was performed before and 6 months after UAE. All embolizations were performed with nsPVA. Outcome measures included uterine artery patency, uterine and dominant fibroid volume, dominant fibroid percentage infarction, presence of ovarian arterial collaterals, and symptom scores assessed by the Uterine Fibroid Symptom and Quality of Life questionnaire (UFS-QOL). Results: Magnetic resonance angiographic evidence of uterine artery recanalization was demonstrated in 90 % of the patients (64 % bilateral, 26 % unilateral) at 6 months. Eighty percent of all dominant fibroids demonstrated >90 % infarction. The mean percentage reduction in dominant fibroid volume was 35 %. No significant difference was identified between nonpatent, unilateral, and bilateral recanalization of the uterine arteries with regard to percentage dominant fibroid infarction or dominant fibroid volume reduction. The presence of bilaterally or unilaterally patent uterine arteries was not associated with inferior clinical outcomes (symptom score or UFS-QOL scores) at 6 months. Conclusion: The high rates of uterine artery patency challenge the current paradigm that nsPVA is a permanent embolic agent and that permanent uterine artery occlusion is necessary to optimally treat uterine fibroids. Despite high rates of uterine artery recanalization in this cohort, satisfactory fibroid infarction rates and UFS-QOL scores were achieved.

    Purpose To evaluate the technical feasibility and clinical outcome of bilateral uterine artery embolization (UAE) as a first-line therapeutic option for bleeding uterine arteriovenous malformation (AVM). Materials and Methods Between 2002 and 2012, 19 patients were diagnosed with acquired uterine AVM clinically and through imaging studies. The clinical characteristics, angiographic features, technical success rate of embolization, procedure-related complications, imaging, and clinical follow-up data were assessed. Clinical success was defined as immediate symptomatic resolution with disappearance of vascular abnormality on subsequent imaging studies. Results A total of 20 bilateral UAE, with or without embolization of extra-uterine feeders, were performed as the first-line treatment. Technical and clinical success rate was 90.0% (18/20) and 89.5% (17/19), respectively. Embolization was incomplete in two patients who had residual extra-uterine fine feeders to the AVM or a procedure-related complication (ruptured uterine artery); the former showed slow regression of the vascular malformation during the observation period, while the latter underwent a successful second bilateral UAE. Immediate clinical success was achieved in the remaining 17 patients after a single session and no recurrence of bleeding was found. Recovery to normal menstrual cycle was seen in all 17 patients with clinical success within one or two months, two of whom subsequently had uneventful intrauterine pregnancies carried to term. Conclusion Bilateral UAE is a safe and effective first-line therapeutic option for the management of bleeding uterine AVMs. However, incomplete embolization due to unembolizable feeders or difficult access into the uterine artery may lead to suboptimal treatment.

    The aim of this review is to summarize the state-of the-art methods that are used in clinical organ transplantation today, as well as the major findings of recent experimental uterus transplantation (UTx) research regarding organ donation/retrieval, ischemic preservation, surgical techniques for anastomosis, immunosuppression and pregnancy. Absolute uterine factor infertility lacks treatment despite the major developments in infertility treatment and assisted reproduction. Concerning uterine factor infertile patients, genetic motherhood is only possible through gestational surrogacy. The latter can pose medical, ethical and legal concerns such as lack of control of life habits during surrogate pregnancy, economic motives for women to become surrogate mothers, medical/psychological pregnancy-related risks of the surrogate mother and uncertainties regarding the mother definition. Thus, surrogacy is non-approved in large parts of the world. Recent advances in the field of solid organ transplantation and experimental UTx provide a favourable and safe background in a scenario in which a human clinical UTx trial can take place. Protocols based on animal research over the last decade are described with a view to providing a scientifically guided approach to human UTx as an experimental procedure in the future. PMID:21900333

    The intensity of gallium-67 scintiscans, lymphocyte counts in bronchoalveolar lavage fluid, and pathologic changes were studied in 26 patients with untreated pulmonary sarcoidosis. Noncaseating granulomas were recognized with significantly greater frequency in stage 2 (80 percent; 8/10 cases) than in stage 1 (43 percent; 6/14 cases). Alveolitis showed little relation to the roentgenographic stage. There was a strong correlation between the intensity of gallium uptake in pulmonary parenchyma and the detection rate of granuloma; however, the detection rate of alveolitis was not statistically different from the intensity of gallium uptake. A highly significant correlation was revealed between the lymphocyte counts in bronchoalveolar lavage fluid and the intensity of alveolitis. These observations suggest that the gallium uptake reflects mainly the presence of granuloma, and the lymphocyte count in bronchoalveolar lavage fluid reflects the intensity of alveolitis in patients with pulmonary sarcoidosis.

    Effects of ambient levels of ozone on cell size and compartments were determined morphometrically for both in situ and lavaged pulmonary alveolar macrophages from rats exposed to filtered air or to filtered air with 0.60 ppm ozone. The ozone exposure was 8 hr/day for 3 days. Significant exposure-related compartmental volume density changes of in situ centriacinar macrophages were: decreased endoplasm (p less than 0.01); increased lysosome-like structures (p less than 0.01); decreased primary lysosomes (p less than 0.01); increased small and large secondary lysosomes (p less than 0.001); and decreased phagosomes/autophagosomes (p less than 0.05). In lavaged macrophages, the only significant exposure-related change was an increase in the density of large secondary lysosomes (p less than 0.01). Mean profile areas of in situ centriacinar macrophages from control and exposed rats were 86.94 micrometers/sup 2/ and 112.04 micrometers/sup 2/, respectively. The average mean cell volume V and mean caliper diameter D of macrophages lavaged from control rats were 1128.45 micrometers/sup 3/ and 12.92 micrometers, respectively, whereas those from exposed rats were 1583.08 micrometers/sup 3/ and 14.46 micrometers, respectively. Exposure-related increases in cell size were seen in both in situ and lavaged macrophages, but more significant differences in cell compartments were seen in the in situ centriacinar macrophages. Morphometry of pulmonary alveolar macrophages after ambient levels of ozone indicated increased uptake, storage, or both rather than cell damage. Comparison of in situ centriacinar and lavaged macrophages from both control and exposed rats revealed significant differences in their volume fractions of nucleus, cytoplasm, ectoplasm, mitochondria, lysosome-like structures, lipid droplets, vacuoles, and phagosome/autophagosomes. These differences between centriacinar and lavaged macrophages indicate different cell populations are sampled by these two methods.

    Magnetic resonance imaging-guided focused ultrasound (MRgFUS) ablation of uterine fibroids provides a minimally invasive outpatient technique for targeting and treating symptomatic uterine fibroids. Magnetic resonance imaging provides a guidance platform that has high temporal and spatial resolution for guiding, as well as thermal monitoring of the procedure. The high-intensity focused ultrasound provides a mechanism for delivering large amounts of energy directly into the fibroid without causing detrimental effects to the nontarget tissues. Early and intermediate follow-up of patients treated with MRgFUS provided promising results on the efficacy of the technique for providing symptom relief to patients. As more long-term follow-up data are published, the efficacy of this technique can be compared to more invasive surgical and minimally invasive catheter treatments.

    Uterine artery Doppler waveform analysis has been extensively studied in the second trimester of pregnancy as a predictive marker for the later development of preeclampsia and fetal growth restriction. The use of Doppler interrogation of this vessel in the first trimester has gained momentum in recent years. Various measurement techniques and impedance indices have been used to evaluate the relationship between uterine artery Doppler velocimetry and adverse pregnancy outcomes. Overall, first-trimester Doppler interrogation of the uterine artery performs better in the prediction of early-onset than late-onset preeclampsia. As an isolated marker of future disease, its sensitivity in predicting preeclampsia and fetal growth restriction in low risk pregnant women is moderate, at 40–70%. Multiparametric predictive models, combining first-trimester uterine artery pulsatility index with maternal characteristics and biochemical markers, can achieve a detection rate for early-onset preeclampsia of over 90%. The ideal combination of these tests and validation of them in various patient populations will be the focus of future research. PMID:25972623

    Background Benign proliferative breast disease without atypia slightly increases breast cancer risk but there are currently few clinical options for breast cancer prevention in this group of women. Methods We conducted a pilot study of women with a past diagnosis of proliferative breast disease with a goal to determine if the characteristics of cells obtained by breast ductal lavage were related to nutritional factors. Results There were 57 women who enrolled. A total of 39 women yielded nipple aspirate fluid (NAF) samples and 36 underwent breast ductal lavage. Five of the lavage samples were acellular and 28 had at least 200 cells. Surprisingly, atypia was present in 11 women. Presence of atypia was associated with slight changes in morphometric features of the epithelial cells such as measures of circularity) as obtained by image analysis, but the only variable significantly different in women with atypia (versus no atypia) was a higher mean body mass index. Body mass index also was significantly correlated with C-reactive protein (CRP) levels in the nipple aspirate fluid, indicating that obesity might have a pro-inflammatory effect on the breast that can contribute to increased rates of atypia. Conclusions Although the clinical significance of atypia in breast ductal lavage is uncertain, these results support further work on prevention of obesity as a strategy for reducing breast cancer risk.

    Adenomyosis is a disease in which ectopic endometrial glands and stromal cells appear in the uterine myometrium. This pathology is common among women of reproductive age, and in addition to chronic pelvic pain and heavy periods it may also cause infertility. The 'tissue injury and repair' mechanism in response to increased intrauterine pressures was proposed as the etiology for migration of fragments of basal endometrium into the myometrial wall. In order to investigate this mechanism, a conceptual two-dimensional model of the uterine wall subjected to intrauterine pressures was implemented using ADINA commercial software. The stress field within the uterine wall was examined for a variety of intrauterine sinusoidal pressure waves with varying frequencies. The results revealed that: (1) as the wavelength of the subjected pressure wave decreased, high concentration of stresses developed near the inner uterine cavity; (2) as the pressure wave frequency increased, high gradients of the stresses were obtained; (3) at menstrual phase, the highest stresses obtained at the endometrial-myometrial interface. Therefore, increased uterine activity results in high stresses which may lead to tissue lesions and detachment of endometrial cells. PMID:25217062

    Endometrial stromal tumors are rare uterine tumors (<1%). Four main categories include endometrial stromal nodule, low-grade endometrial stromal sarcoma (LG-ESS), high-grade endometrial stromal sarcoma (HG-ESS), and uterine undifferentiated sarcoma (UUS). This review is a series of articles discussing the uterine sarcomas. LG-ESS, a hormone-dependent tumor harboring chromosomal rearrangement, is an indolent tumor with a favorable prognosis, but characterized by late recurrences even in patients with Stage I disease, suggesting the requirement of a long-term follow-up. Patients with HG-ESS, based on the identification of YWHAE-NUTM2A/B (YWHAE-FAM22A/B) gene fusion, typically present with advanced stage diseases and frequently have recurrences, usually within a few years after initial surgery. UUS is, a high-grade sarcoma, extremely rare, lacking a specific line of differentiation, which is a diagnosis of exclusion (the wastebasket category, which fails to fulfill the morphological and immunohistochemical criteria of translocation-positive ESS). Surgery is the main strategy in the management of uterine sarcoma. Due to rarity, complex biological characteristics, and unknown etiology and risk factors of uterine sarcomas, the role of adjuvant therapy is not clear. Only LG-ESS might respond to progestins or aromatase inhibitors. PMID:27590366

    We decided to evaluate the efficacy and complications of uterine artery embolization (UAE) in patients with symptomatic uterine fibroids. Sixty-five premenopausal patients, without considering the fibroids size and its location, were treated by bilateral UAE. At baseline and after 3, 6, and 12 months MRI was obtained to determine the uterine length and fibroid diameter. In addition, symptoms of the patients were documented at these follow-up schedules. UAE was successful in 62 (95.4%) cases. Complete infarction rate of the fibroid was 83.1%. After 12 months, the uterine length showed a decrease of 55.7% (mean of 9.4 cm) and the diameter of the dominant fibroid revealed a decrease of 52.1% (mean of 3.4 cm). Menorrhagia improved in 45 cases (91.8%), abdominal mass in 24 cases (82.28%), urinary symptoms in 17 cases (85%), pelvic pain in 21 cases (84%), and dysmenorrhea in 25 cases (80.6%). At final follow-up performed after one year, complete infarction of the fibroma was demonstrated in 49 patients (83.1%). Two cases achieved successful pregnancy in the one year follow-up period. Five patients developed post-embolization syndrome which necessitated admission to the hospital. Twenty-two patients presented and complained of pain for which outpatient pain management was done. UAE was a successful treatment for uterine fibroids that preserved the uterus, had minimal complications, and required short hospitalization and recovery. PMID:26925914

    A variety of chemotherapeutic agents have been used for treating recurrent or advanced stage uterine leiomyosarcoma (ULMS). The response rates of these current agents are disappointing, with partial response rates varying from 0% to 33%, and complete response rates varying from 0% to 8%. Recent studies have documented many molecular changes in ULMSs. Prominent amongst these are gains of growth factors C-MYC, Bcl-2, K-ras, and Ki-67, and losses in tumor suppressors p16, p53, Rb1, ING2 and D14S267. Various techniques that have been used to target these molecules are presented. Targeting specific therapies at these underlying molecular changes could potentially yield better response rates with fewer side effects. PMID:26858789

    Puerperal uterine inversion is a rare and potentially life-threatening complication of a mismanaged third stage of labour. Early diagnosis is mandatory for proper management of the patient. Complete uterine inversion is a clinical diagnosis. However, incomplete uterine inversion is difficult to identify and warrants further workup. Sonographic evaluation, although a bedside procedure, may be confusing. The conspicuity of findings is much greater on MR examination than on ultrasound. Only a few diagnostic imaging findings in uterine inversion have been described in previous reports. We present the case of a 26-year-old woman who had a full-term vaginal delivery and presented after 20 days with acute urinary retention and mild vaginal bleeding. She was diagnosed as a case of neglected subacute incomplete uterine inversion. Both greyscale and Doppler sonographic and MR features of the case are described with an emphasis on better delineation of uterine and adnexal anatomy on MR imaging. PMID:24619161

    We describe a case of recurrent uterine rupture at the site of a previous rupture. Our patient had a history of right interstitial pregnancy with spontaneous uterine fundal rupture at 18 weeks of pregnancy. During her subsequent pregnancy, she was monitored closely by a senior consultant obstetrician. The patient presented at 34 weeks with right hypochondriac pain. She was clinically stable and fetal monitoring showed no signs of fetal distress. Ultrasonography revealed protrusion of the intact amniotic membranes in the abdominal cavity at the uterine fundus. Uterine rupture is a rare but hazardous obstetric complication. High levels of caution should be exercised in patients with a history of prior uterine rupture, as they may present with atypical symptoms. Ultrasonography could provide valuable information in such cases where there is an elevated risk of uterine rupture at the previous rupture site. PMID:26106245

    Identifying patients at risk for preeclampsia would allow an increase in perinatal surveillance and possibly decrease the inherent maternal and fetal morbidity and mortality associated with severe preeclampsia and eclampsia. First and second trimester uterine artery Doppler velocimetry is a sensitive screening tool for the detection of preeclampsia and intrauterine growth retardation (IUGR) requiring delivery before 34 weeks. The performance of uterine artery Doppler velocimetry as a screening test depends on the prevalence of the adverse outcome in the studied population and whether the adverse outcomes are assessed individually or collectively as a group. Future research in this area should focus on identification of additional markers that may be incorporated into a prediction model for early identification of patients at risk for adverse outcomes.

    2016-07-01

    Uterine leiomyomas (fibroids) are the most common benign neoplasms in premenopausal women, which confer significant morbidity during the reproductive years and represent a significant public health issue. The incidence of fibroids has been associated with African-American race, early onset of menarche, early parity, and environmental/dietary exposures. These sex steroid-responsive uterine tumors are characterized by de novo transformation of the myometrium into fibroids via excessive formation of the extracellular matrix (ECM). Cytogenic anomalies, mutations in mediator complex subunit 12 (MED 12), and aberrant DNA methylation/demethylation have been observed, but have not been reported as direct mediators of fibroid development. Recent advances in epigenetics have implied a functional role of G protein-coupled receptor 10 (GPR10) overexpression and irregular microRNA expression in the pathobiology of fibroids that require future investigation. Herein, the impact of epidemiologic and genetic factors on the incidence and development of fibroids is reviewed. PMID:26725703

    2016-07-01

    The role of ovarian steroid hormones in the pathogenesis of uterine fibroids is supported by epidemiological, clinical, and experimental evidence. Estradiol and progesterone induce mature leiomyoma cells to release mitogenic stimuli to adjacent immature cells, thereby providing uterine leiomyoma with undifferentiated cells that are likely to support tumor growth. Progesterone action is required for the complete development and proliferation of leiomyoma cells, while estradiol predominantly increases tissue sensitivity to progesterone by increasing the availability of progesterone receptors (PRs). The selective estrogen receptor modulator (SERM) raloxifene and the selective PR modulators (SPRMs) mifepristone, asoprisnil, and ulipristal acetate have been shown in clinical trials to inhibit fibroid growth. The role of sex steroids is critical for leiomyoma development and maintenance, but a number of autocrine and paracrine messengers are involved in this process; hence, numerous pathways remain to be explored in therapeutic innovations for treating this common disease.

    Uterine fibroids (leiomyomata) are extremely common lesions that are associated with detrimental effects including infertility and abnormal uterine bleeding. Fibroids cause molecular changes at the level of endometrium. Abnormal regulation of growth factors and cytokines in fibroid cells may contribute to negative endometrial effects. Understanding of fibroid biology has greatly increased over the last decade. Although the current armamentarium of Food and Drug Administration-approved medical therapies is limited, there are medications approved for use in heavy menstrual bleeding that can be used for the medical management of fibroids. Emergence of the role of growth factors in pathophysiology of fibroids has led researchers to develop novel therapeutics. Despite advances in medical therapies, surgical management remains a mainstay of fibroid treatment. Destruction of fibroids by interventional radiological procedures provides other effective treatments. Further experimental studies and clinical trials are required to determine which therapies will provide the greatest benefits to patients with fibroids. PMID:24819877

    In assessing a patient with excessive uterine bleeding, the clinician should consider systemic causes in the differential diagnosis. Both hereditary and acquired conditions can result in mucous membrane bleeding, including menorrhagia, epistaxis, and gum bleeding, as well as excessive bruising. Among hereditary conditions, von Willebrand disease (vWD) is by far the most common, affecting an estimated 1% of the population worldwide. It is important to consider the possibility of vWD, and to establish the proper diagnosis (including subtype), as safe, effective, and easy-to-use treatment is available for most persons with this disorder. This review also covers a number of other systemic conditions that can be manifested by excessive uterine bleeding, including congenital deficiency of factor XI, idiopathic thrombocytopenic purpura and other acquired platelet disorders, acquired autoantibodies against factor VIII (FVIII), and vitamin K deficiency states.

    2009-10-01

    The physiological basis of uterine contractility in laying hens is not well understood, but a better understanding is important for understanding the mechanisms governing egg laying. The characteristics of uterine contractility arising spontaneously or by prostaglandin F(2alpha) (PGF(2alpha)) stimulation were therefore examined and the underlying mechanisms investigated. Uterine strips were isolated from laying hens 4h before oviposition and force measured. These strips remained healthy in vitro and produced regular spontaneous contractions. The contractions were phasic and could be recorded for several hours. Exposure to nifedipine, the specific L-type Ca channel blocker, led to the abolition of force. The contraction amplitude and frequency were significantly increased when Bay K8644, an agonist of L-type Ca channels, was applied or when the concentration of extracellular Ca was elevated. Spontaneous contractions were also significantly inhibited by wortmannin, the specific inhibitor of myosin light chain kinase (MLCK). When 1 microM PGF(2alpha) was applied to spontaneously contracting uterus, it significantly increased their amplitude and frequency of the contractions. As with spontaneous contractions, PGF(2alpha)-induced force production was abolished by nifedipine and wortmannin. In the absence of extracellular Ca, a small but tonic force was generated upon application of PGF(2alpha) which was not affected by wortmannin. Thus, extracellular Ca entry and MLCK phosphorylation are essential for uterine force production occurring spontaneously or by PGF(2alpha) stimulation. Our data supports the conclusion that the pathway dependent on extracellular Ca entry and MLCK phosphorylation predominates during PGF(2alpha) stimulation but suggests some involvement of an alternative force-producing pathway, presumably Ca-sensitization.

    Fusobacterium necrophorum is infrequently implicated as a pathogenic organism. When pathogenic, the typical clinical presentation is that of pharyngitis, cervical adenopathy, and unilateral thrombophlebitis of the internal jugular vein. Infections caused by Fusobacterium necrophorum within the fields of obstetrics and gynecology have been infrequently reported. We describe a 19-year-old woman who underwent a cesarean delivery complicated by sepsis and purulent uterine necrosis secondary to Fusobacterium necrophorum infection. PMID:26000185

    In addition to surgical methods of treating uterine fibroids, numerous non-invasive treatments have been developed. Many of these involve the use of hyperthermia, the heating of tissue by a variety of methods. These include the use of lasers, radiofrequency, microwave energy and high intensity focused ultrasound, guided by both ultrasound and magnetic resonance imaging. In this review we examine the technology behind these treatment modalities and review the current evidence for their use. PMID:25815582

    This is the first reported case of ectopic prostatic tissue in the uterine cervix, diagnosed in a 38-year-old woman. A cluster of benign prostatic glands with cribriform and papillary patterns and focal squamous metaplasia occupied the superficial endocervical stroma. The glands were immunoreactive for prostatic specific antigen and prostatic specific acid phosphatase. This lesion, which could be confused with microglandular hyperplasia, mesonephric rests, or adenocarcinoma in situ may represent an embryonic rest. PMID:9421098

    Spontaneous or electrically stimulated activity of the uterus is measured isometrically in vitro by integrating tension against time. Uterine contractions move the operating rod of a potentiometer transducer, the output voltage from which is coupled to an electrical integrator motor and a servo recorder. Several parameters of uterine activity can be expressed in a single measurement, and a record of isometric contractions is obtained simultaneously. Oxytocin can be assayed accurately and the effect of drugs on uterine motility can be measured. PMID:13918066

    In this article, we present the views on uterine cancer of the ancient Greek physicians. We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative. PMID:26537093

    Uterine leiomyomas are an extremely rare cause of acute urinary retention in women. The delay in diagnosing uterine leiomyomas presenting with acute urinary retention further complicates the management. The rarity of the condition makes it difficult to plan either prospective or retrospective trials. Hence, most of the evidence comes from case reports or series. We report a case series of acute urinary retention in women with uterine leiomyomas and discuss the pathophysiology, diagnosis and management options. PMID:27190903

    New insemination techniques allow a tremendous sperm reduction for successful artificial insemination (AI) if highly diluted semen is deposited in the tip of the uterine horn and close to the utero-tubal junction. High sperm losses are known to occur during uterine passage and it was the general question whether specific binding mechanisms are involved. Upon arrival in the uterus, spermatozoa are confronted with mainly two different cell types: uterine epithelial cells (UEC) and neutrophilic granulocytes (polymorphonuclear neutrophil, PMN). As cell-sperm interactions can hardly be observed in vivo, an ex vivo system was established to study the interaction between spermatozoa and the UEC. Uterine segments (10 cm) from freshly slaughtered synchronized juvenile gilts were inseminated for 60 min at 38 degrees C. Thereafter spermatozoa were recovered, counted flow cytometrically and examined for changes in viability and mitochondrial membrane potential (MMP). Significantly less spermatozoa with a functioning MMP and intact plasma membranes could be retrieved (55 +/- 7%), while the number of damaged spermatozoa hardly changed (93 +/- 12%), indicating retention of viable sperm cells in the uterine lumen. The interactions between porcine PMN and spermatozoa (motile, immotile, membrane-damaged) were studied in coincubation assays in vitro. The binding of membrane-damaged sperm cells to PMN was virtually non-existent (3 +/- 2%). Viable and motile spermatozoa attached to PMN without being phagocytosed within 60 min (45 +/- 3%), whereas binding to sodium fluoride (NaF)-immobilized spermatozoa was reduced to 20 +/- 2%. The binding of viable sperm to PMN is most likely not lectin-dependent; although both viable cell types were shown to express a broad range of different lectin-binding sugar residues, none of the lectins tested was able to selectively block PMN-sperm binding significantly. The results of the study suggest that viable spermatozoa are already subject to selective

    The purpose of this study was to prospectively assess the safety and effectiveness of uterine artery embolization (UAE) using porous gelatin particle (PGP; Gelpart; Asuterasu, Tokyo, Japan) for symptomatic uterine fibroids. Twenty-five consecutive premenopausal women underwent UAE with PGP. The angiographic end point of embolization was near stasis of the ascending uterine artery. Pelvic magnetic resonance imaging (MRI) was obtained before and after the procedure. Complications were assessed. The outcomes of technique, infarction rates of all fibroid tissue after UAE with contrast-enhanced MRI, change in symptoms and quality of life using serial Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaires, and additional interventions were evaluated. Bilateral UAE was successfully performed in all patients. Enhanced MRI 1 week after UAE showed that 100% infarction of all fibroid tissue was achieved in 65% (15 of 23) of patients; 90-99% infarction was achieved in 35% (8 of 23) of patients. Mean follow-up was 12 months (range 1-20). Symptom and QOL scores at baseline were 47.2 and 61.7, respectively. Both scores significantly improved to 26.3 (P < 0.001) and 82.4 (P < 0.001) at 4 months and to 20.4 (P < 0.001) and 77.6 (P < 0.001) at 1 year, respectively. No additional gynecologic interventions were performed in any patient. There were no major complications. Minor complications occurred in two patients. UAE using PGP is a safe and effective procedure and shows that outcomes after UAE, as measured with enhanced MRI and UFS-QOL questionnaires, seem comparable with those of UAE using other embolic agents. PGP is a promising embolic agent used for UAE to treat symptomatic uterine fibroids. Further comparative study between PGP and other established embolic agents is required.

    In order to ensure safe magnetic resonance-guided, high-intensity focused, ultrasound ablation of uterine leiomyomas, the ultrasound beam path should be free of intervening scar and bowel. Pre-treatment MRI of a 9-cm long and 7.7-cm wide leiomyomatous uterus in a 39-year-old woman with menorrhagia and abdominopelvic pain initially demonstrated a focused ultrasound treatment path without a bowel between the uterus and the abdominal wall. On the day of ablation, however, multiple loops of bowel were observed in the ultrasound beam path by MRI. Uterine repositioning was accomplished with a 76-mm donut vaginal pessary, which anteverted the fundus and successfully displaced the bowel. A vaginal pessary may aid in repositioning an axial or retroverted uterus to enable ablation of uterine leiomyomas. PMID:26584482

    The records of nine female intact dogs with histologically confirmed uterine tumors were reviewed retrospectively, and the related radiographic and ultrasonographic signs of the lesions detected were recorded. Radiography revealed a soft-tissue opacity between the urinary bladder and colon in six of seven dogs with uterine body and/or cervical tumors, and a soft-tissue opacity in the midventral abdomen in two dogs with uterine horn tumors. Ultrasonography revealed masses in all dogs with uterine body/cervical tumors and could delineate the origin of the mass in one of two dogs with uterine horn tumors. The mass was characterized ultrasonographically as solid in three dogs (all leiomyomas), solid with cystic component in four dogs (two adenocarcinomas, one leiomyoma, and one fibroleiomyoma), and cystic in two (both leiomyomas). Hyperechoic foci in the mass were observed in three dogs. Ultrasonography was a useful method for demonstrating uterine body and/or cervical tumors. However, it was not possible to ascertain sonographically that a mass originated in a uterine horn unless there was associated evidence of uterine horn to which the mass could be traced. The ultrasonographic appearance of uterine tumors was variable, and the type of neoplasm could only be determined by taking biopsies of the mass. PMID:25028432

    Objective To compare the effectiveness and acceptability of outpatient polypectomy with inpatient polypectomy. Design Pragmatic multicentre randomised controlled non-inferiority study. Setting Outpatient hysteroscopy clinics in 31 UK National Health Service hospitals. Participants 507 women who attended as outpatients for diagnostic hysteroscopy because of abnormal uterine bleeding and were found to have uterine polyps. Interventions Participants were randomly assigned to either outpatient uterine polypectomy under local anaesthetic or inpatient uterine polypectomy under general anaesthesia. Data were collected on women’s self reported bleeding symptoms at baseline and at 6, 12, and 24 months. Data were also collected on pain and acceptability of the procedure at the time of polypectomy. Main outcome measures The primary outcome was successful treatment, determined by the women’s assessment of bleeding at six months, with a prespecified non-inferiority margin of 25%. Secondary outcomes included generic (EQ-5D) and disease specific (menorrhagia multi-attribute scale) quality of life, and feasibility and acceptability of the procedure. Results 73% (166/228) of women in the outpatient group and 80% (168/211) in the inpatient group reported successful treatment at six months (intention to treat relative risk 0.91, 95% confidence interval 0.82 to 1.02; per protocol relative risk 0.92, 0.82 to 1.02). Failure to remove polyps was higher (19% v 7%; relative risk 2.5, 1.5 to 4.1) and acceptability of the procedure was lower (83% v 92%; 0.90, 0.84 to 0.97) in the outpatient group Quality of life did not differ significantly between the groups. Four uterine perforations, one of which necessitated bowel resection, all occurred in the inpatient group. Conclusions Outpatient polypectomy was non-inferior to inpatient polypectomy. Failure to remove a uterine polyp was, however, more likely with outpatient polypectomy and acceptability of the procedure was slightly lower. Trial

    Background Uterine artery embolisation (UAE) has evolved as a minimally invasive and effective alternative, treatment modality for women with symptomatic fibroids. We discuss our initial experience of UAE in the management of symptomatic fibroids. Methods Twenty five symptomatic patients of uterine fibroids were treated with UAE by selectively cannulating and injecting poly vinyl alcohol particles into the uterine arteries. Post treatment follow up was done at 2 and 6 months respectively. Results Pre-treatment, the sizes of fibroids were between 3.9 and 10.9 cm (mean 7.4) on ultrasonography. Of the total 25 patients, 49 uterine arteries were embolised with a technical success rate of 98%. Menorrhagia persisted in 7 patients, dysmenorrhea in 4 patients and pressure symptoms in 2 patients respectively in follow up study of six months which corresponds to a reduction in symptoms by 68% for menorrhagia, 71% for dysmenorhoea and 75% for those with pressure symptoms respectively. At 2 months follow-up post embolisation, the mean diameter of the fibroid was 4.03 cm (range 2–5.2 cm) and at 6 months 3.2 cm (range 1.3–4.1 cm), corresponding to size reduction of 45.5% and 57%, respectively. Follow up with ultrasonography at 2 and 6 months period showed successful fibroid reduction in 24 patients with corresponding reduction in the symptomatology. One patient remained symptomatic with increase in fibroid size and had to undergo hysterectomy. Conclusion Uterine artery embolisation can be considered as an alternative to hysterectomy in appropriately selected symptomatic patients of uterine fibroids. PMID:26288491

    Magnetic resonance imaging (MRI) is increasingly applied in the evaluation of uterine fibroids. However, little is known about the reproducibility of MRI in the assessment of uterine fibroids. This study evaluates the inter- and intraobserver variation in the assessment of the uterine fibroids and concomitant adenomyosis in women scheduled for uterine artery embolization (UAE). Forty patients (mean age: 44.5 years) with symptomatic uterine fibroids who were scheduled for UAE underwent T{sub 1}- and T{sub 2}-weighted MRI. To study inter- and intraobserver agreement 40 MR images were evaluated independently by two observers and reevaluated by both observers 4 months later. Inter- and intraobserver agreement was calculated using Cohen's {kappa} statistic and intraclass correlation coefficient for categorical and continuous variables, respectively. Inter-observer agreement for uterine volumes ({kappa} = 0.99, p < 0.0001), dominant fibroid volumes ({kappa} = 0.98, p {<=} 0.0001), and number of fibroids ({kappa} = 0.88; CI, 0.77-0.93; p < 0.0001) was excellent. For the T{sub 1}- and T{sub 2}-weighted signal intensity of the dominant fibroid there was good agreement between the observers (87%; 95% CI, 71.9%-95.6%) and the intraobserver agreement was good for observer A (95%; 95% CI, 83.1%-99.4%) and moderate for observer B ({kappa} = 0.47). The interobserver agreement with respect to the presence of adenomyosis was good ({kappa} = 0.73, p < 0.0001), while both intraobserver agreements were fair to moderate (observer A, {kappa} = 0.55, p = 0.0003; and observer B, {kappa} = 0.66, p < 0.0001). In conclusion, MRI criteria used for the selection of suitable UAE patients show good inter- and intraobserver reproducibility.

    Purpose To evaluate the clinical feasibility and diagnostic accuracy of three-dimensional (3D) quantitative magnetic resonance (MR) imaging for the assessment of total lesion volume (TLV) and enhancing lesion volume (ELV) before and after uterine artery embolization (UAE). Materials and Methods This retrospective study included 25 patients with uterine fibroids who underwent UAE and received contrast-enhanced MR imaging before and after the procedure. TLV was calculated using a semiautomated 3D segmentation of the dominant lesion on contrast-enhanced MR imaging, and ELV was defined as voxels within TLV where the enhancement exceeded the value of a region of interest placed in hypoenhancing soft tissue (left psoas muscle). ELV was expressed in relative (% of TLV) and absolute (in cm3) metrics. Results were compared with manual measurements and correlated with symptomatic outcome using a linear regression model. Results Although 3D quantitative measurements of TLV demonstrated a strong correlation with the manual technique (R2 = 0.93), measurements of ELV after UAE showed significant disagreement between techniques (R2 = 0.72; residual standard error, 15.8). Six patients (24%) remained symptomatic and were classified as nonresponders. When stratified according to response, no difference in % ELV between responders and nonresponders was observed. When assessed using cm3 ELV, responders showed a significantly lower mean ELV compared with nonresponders (4.1 cm3 [range, 0.3–19.8 cm3] vs 77 cm3 [range, 11.91–296 cm3]; P < .01). Conclusions The use of segmentation-based 3D quantification of lesion enhancement is feasible and diagnostically accurate and could be considered as an MR imaging response marker for clinical outcome after UAE.

    The use of a combination of manometric and electromyographic methods provided a reliable technique for evaluating variations in uterine activity in conscious macaque monkeys and women. The technique was particularly useful for obtaining data on the influence of steroid hormones. During the spontaneous menstrual cycle of the macaque, uterine motility, after being weak and poorly synchronized during the follicular phase, became still weaker with impaired synchronization during the luteal phase and then much stronger and well-synchronized at the time of menstruation. There was no evidence in vivo of any relationship between the existence of gap junctions in the myometrium of non-pregnant animals and the various patterns of uterine motility. During the last third of pregnancy in macaques, the initiation of electrical activity in various uterine areas was always synchronous with and related to mechanical contraction. The same results were obtained in preparturient women. Thus, improved uterine coordination does not appear to be the mechanism by which the uterine contractile strength increases to expulse the foetus at the end of pregnancy. Apart from the particular situation of non-pregnant animals under progestative influence, in which activity was constantly non-propagated, we could not find any evidence of a general pattern which would indicate only one site for the initiation of activity and its extension to the whole uterus.

    Uterine artery embolization (UAE) is a well-established therapy for uterine fibroids, with safety and efficacy demonstrated in several comparative randomized trials. It is a minimally invasive procedure, which allows for rapid recovery and return to normal activities. Most studies demonstrate outcomes similar to those of myomectomy with a reintervention rate of 20% to 30% at 5 years after therapy. While pregnancy is often successful after UAE, limited comparative data suggest that myomectomy may be preferred in those patients who have not had prior fibroid interventions. UAE should be discussed as an option for most women presenting for treatment of fibroids. PMID:26630074

    To explore the potential mechanism of how uterine innervations would affect the uterine mast cell (MC) population and functions during the periimplantation. We herein first examined the consequence of uterine neurectomy on embryo implantation events. We observed that amputation of autonomic nerves innervating the uterus led to on-time implantation failure in rats. Exploiting MC culture and ELISA approaches, we then further analyzed the effect of neurectomy on cellular histamine levels and its release from uterine MCs, to elucidate the relation of the autonomic nerves and local cellular immunity in the uterine during early pregnancy. We observed that disconnection of autonomic nerve innervation significantly increased the population of uterine MCs. Most interestingly, these increased number of uterine MCs in neuroectomized rats contained a much reduced cellular level of histamine. Our subsequent challenge experiments revealed that uterine MCs in nerve amputated rats exhibited enhanced histamine releasing rate in response to substance P and antiIgE, suggesting loss of nerve innervation in the uterus not only increases the population of uterine MCs, but also facilitates the release of histamine from MCs, thus subsequently interfere with the normal implantation process. Collectively, our findings provide a new line of evidence supporting the concept that immune-neuro-endocrine network plays important role during pregnancy establishment and maintenance.

    The Authors have reported the cytological patterns of malignant primitive uterine fibrous histiocytoma of a 57 year old woman. The endometrial cytological sampling was performed by an aspiration technique using a feeding-tube; a necrotic-haemorrhagic background filled with hymphocytes and polymorphonuclear leukocytes, and a mixture of highly anaplastic histiocytic and fibroblastic type cells, associated with undifferentiated small round cells, has been described. The result of the histological examination performed on the surgical specimen was the following: polymorphic malignant neoplasia characterized by spindle-like and giant plurinucleated cells, phagocytosis features, endoluminal polypoid growth, wide infiltration of the miometrium two thirds deep, vascular space invasion of the uterine wall and the hilus of the ovaries. The histological features and immunohistochemical analysis were consistent with malignant fibrous histiocytoma in the pleomorphic variety. PMID:1965802

    Pulmonary alveolar proteinosis (PAP) is a rare interstitial lung disease that develops as a result of defects in the clearance of surfactant by alveolar macrophages. The accumulation of lipid- and protein-rich substances in the alveoli constitutes the main pathology of this disease. PAP has three types of aetiology: autoimmune (primary), congenital and secondary. The most common form in adults is autoimmune PAP. Whole lung lavage is a commonly performed method for treatment of this form of disease, especially in more severe cases. Performed under general anaesthesia, the material deposited in the alveoli is removed by washing. In this paper, we present a whole lung lavage under anaesthesia in a PAP patient who had severe respiratory failure. PMID:27366571

    PURPOSE We encountered a case where an infection with group A streptococcus (GAS; ie, Streptococcus pyogenes) initially caused primary peritonitis and then subsequently caused streptococcal toxic shock syndrome. The patient’s life was likely saved by an emergency laparotomy followed by extensive peritoneal lavage and drainage. CASE PRESENTATION A 40-year-old woman was admitted to the Emergency Department for lower abdominal pain and numbness in the extremities. She presented with systemic inflammatory response syndrome. An emergency laparotomy was performed, and ascites that resembled pus and general peritonitis were noted. Peritoneal lavage and drainage were performed, and GAS was isolated from peritoneal fluid. Gram staining of cervical polyp specimens revealed Gram-positive bacteria. CONCLUSIONS The patient was diagnosed with streptococcal toxic shock syndrome due to an ascending GAS infection originating from vagina. PMID:27579001

    Recently we observed a case in which the cyclosporin A absorption decreased after treatment with GoLytely lavage solution in a kidney transplant patient. In this study, we confirmed the decrease of the blood concentration of cyclosporin A after oral administration by GoLytely (Macrogol 3350) based on experiments with rats. The peak blood cyclosporin A concentration, and the area under the blood drug concentration-time curve from 0 to 24 h in the GoLytely-administered group were significantly lower than the control group. In the case of gastrointestinal dysfunction such as diarrhoea, or in treatment with laxatives such as GoLytely lavage solution, whole blood cyclosporin levels must be carefully monitored, and intravenous cyclosporin A may be more suitable for providing adequate immunosuppression.

A polymerase chain reaction was positive for Clostridium Difficile. Due to the failure to improve after full medical treatment, a derivative loop ileostomy and intra-operatory colonic lavage were performed, leaving a Foley catheter in the proximal colon. In the postoperative period, anterograde colonic instillations of Vancomycin flushes through the catheter were performed every 6 hours. Forty eight hours after surgery, the patient improved. A colonoscopy prior to discharge showed resolution of the pseudomembranous colitis. PMID:26203580

    Carcinosarcoma arising from uterine adenomyosis is extremely rare. We encountered such a patient and herein provide a review of the literature. A 56-year-old woman was referred for a huge pelvic tumor, suspected to be an advanced uterine leiomyosarcoma. Intraoperative inspection revealed a mass, mainly located in the uterine myometrium, invading the uterine serosa. The tumor had previously spontaneously ruptured and disseminated to the pelvic cavity. Pathological and immunohistochemical examination revealed an infiltrative pattern of biphasic tumor cells composed of endometrioid adenocarcinoma and a nonepithelial component with rhabdomyosarcomatous differentiation. Benign endometrial glands with stromal cells were found adjacent to the area of the carcinosarcoma. The endometrium and both ovaries and fallopian tubes were microscopically free of tumor cells. The final diagnosis was heterologous type carcinosarcoma with rhabdomyosarcomatous differentiation, originating from uterine adenomyosis. PMID:26663238

    A patient with a history of total knee arthroplasty and 5 subsequent revisions presented with pain. His preoperative construct consisted of a revision implant with porous in-growth stem extensions. He was indicated for revision surgery for a painful implant with progressive arthrofibrosis. The surgery proceeded uneventfully until we were unable to loosen the proximal portion of the ingrown femoral stem. After the distal femur was removed, a trephine was used to break the bone ingrowth from the distal portion of the stem. Flexible osteotomes were used to loosen the bone-prosthetic interface, but they were unable to penetrate deep enough, and they eventually bent under the applied loads. Nonflexible osteotomes were also used without success, and we were still unable to remove the stem from within the femur. Slap hammers, vice grips, and other devices were used to try to remove the stem, but attempts were unsuccessful. We hung a 3-liter bag of ice-cold (4 °C) saline and ran all 3 liters of saline, under gravity pressure, retrograde down the femoral shaft in an attempt to contract the metal and allow for the removal of the stem. We then attached a stem extension screw to the incarcerated femoral stem and were able to remove it with minimal effort using a back-slap device. We inspected the prosthesis and found no abnormalities of the stem to explain its incarceration and no iatrogenic perforations in the femur. This case demonstrates a useful technique that should be kept in a revision surgeon's armamentarium for the removal of incarcerated porous ingrowth stems. PMID:22146213

    Embryo implantation is a complex interaction between maternal endometrium and embryonic structures. Failure to implant is highly recurrent and impossible to diagnose. Inflammation and infections in the female reproductive tract are common causes of infertility, embryo loss, and preterm labor. The current work describes how the activation of endometrial Toll-like receptor (TLR) 2 and 2/6 reduces embryo implantation chances. We developed a morphometric index to evaluate the effects of the TLR 2/6 activation along the uterine horn (UH). TLR 2/6 ligation reduced the endometrial myometrial and glandular indexes and increased the luminal index. Furthermore, TLR 2/6 activation increased the proinflammatory cytokines such as interleukin (IL)-1beta and monocyte chemotactic protein (MCP)-1 in UH lavages in the preimplantation day and IL-1 receptor antagonist in the implantation day. The engagement of TLR 2/6 with its ligand in the UH during embryo transfer severely affected the rate of embryonic implantation (45.00% ± 6.49% vs. 16.69% ± 5.01%, P < 0.05, control vs. test, respectively). Furthermore, this interference with the embryo implantation process was verified using an in vitro model of human embryo implantation where trophoblast spheroids failed to adhere to a monolayer of TLR 2- and TLR 2/6-activated endometrial cells. The inhibition of TLR receptors 2 and 6 in the presence of their specific ligands restored the ability of the spheroids to bind to the endometrial cells. In conclusion, the activation of the innate immune system in the uterus at the time of implantation interfered with the endometrial receptivity and reduced the chances of implantation success.

    A necrotizing arteritis in the uterine cervix is described as an incidental finding in surgical material from 10 patients. The histological features are compared with those seen in polyarteritis nodosa. Subintimal hyaline deposition and a relative paucity of neutrophil and eosinophil polymorphs characterized the lesion but the histological appearance was never sufficiently specific to exclude confidently the possibility of polyarteritis nodosa. None of the patients had evidence of multisystem disease either at the time of operation or at subsequent follow-up assessment. Images PMID:4138761

    Uterine fibroid is the most common tumor in women of reproductive age. Depending on the size and location they can cause variety of symptoms. The clinical presentation may include bleeding disorders, infertility, pelvic pain and dysmenorrhea as well. Detection and precise evaluation of the number, size and location of myomas is possible due to advances in imaging and endoscopic methods. Treatment of fibroids depends on the severity and type of symptoms. There are medical, radiological and surgical options for treatment. Debates on fibroid management are widely published and are in focus recently, related to the "fibroid-scandal" occurred in the United States. PMID:27177787

    Uterine fibroids are a common condition that can be debilitating and are the leading benign cause of hysterectomy. Women often live with the symptoms rather than choose hysterectomy, but survey studies have shown that work, social life, and physical activities are hindered by fibroid symptoms. Offering alternative therapies tailored to a woman's symptoms will allow her to choose a treatment that fits her needs and to preserve her uterus and fertility. The minimally invasive treatment options have a faster recovery and lower surgical risk than hysterectomy, but may require reintervention. One pharmacologic treatment offers short-term, intermittent therapy with lasting effects. PMID:27521875

    In 60 patients with a live fetus and an intra-uterine hematoma (IUH) proven by ultrasonic scanning the outcome of pregnancy was spontaneous abortion in 12% and premature delivery in 10%. No correlation between the outcome of the pregnancy and the maximum size of the hematoma or the week of detection was found. A subplacentar localization of the hematoma was associated with a higher, but not statistically significant, incidence of spontaneous abortion than a subchorionic localization. Spontaneous abortion most often occurred in the first weeks after the formation of the hematoma. PMID:1855608

    Infection is a leading cause of preterm birth (PTB). A focus of many studies over the past decade has been to characterize microorganisms present in the uterine cavity and document any association with negative pregnancy outcome. A range of techniques have been used to achieve this, including microbiological culture and targeted polymerase chain reaction assays, and more recently, microbiome-level analyses involving either conserved, phylogenetically informative genes such as the bacterial 16S rRNA gene or whole shotgun metagenomic sequencing. These studies have contributed vast amounts of data toward characterization of the uterine microbiome, specifically that present in the amniotic fluid, fetal membranes, and placenta. However, an overwhelming emphasis has been placed on the bacterial microbiome, with far less data produced on the viral and fungal/yeast microbiomes. With numerous studies now referring to PTB as a polymicrobial condition, there is the need to investigate the role of viruses and fungi/yeasts in more detail and in particular, look for associations between colonization with these microorganisms and bacteria in the same samples. Although the major pathway by which microorganisms are believed to colonize the uterine cavity is vertical ascension from the vagina, numerous studies are now emerging suggesting hematogenous transfer of oral microbiota to the uterine cavity. Evidence of this has been produced in mouse models and although DNA-based evidence in humans appears convincing in some aspects, use of methodologies that only detect viable cells as opposed to lysed cells and extracellular DNA are needed to clarify this. Such techniques as RNA analyses and viability polymerase chain reaction are likely to play key roles in the clinical translation of future microbiome-based data, particularly in confined environments such as the uterus, as detection of viable cells plays a key role in diagnosis and treatment of infection.

    Pressure ulcers are major complications of reduced mobility and/or sensation. Pulsatile lavage therapy delivers localized hydrotherapy directly to the wound utilizing a pulsatile pressurized stream of normal saline. The purpose of this study was to evaluate the clinical safety of pulsatile lavage therapy, provided daily at the bedside, in routine management of Stage III and Stage IV pressure ulcers. Charts from 28 male patients with Stage III and Stage IV pressure ulcers and spinal cord injury (SCI) or spinal cord disorders (SCD) were retrospectively reviewed for documentation of adverse events/safety concerns. Mean therapy duration was 46 days (SD 37 days, range 6-152 days). Treatment was interrupted for 6 days in one patient due to minor wound bleeding. No other adverse events, including backsplash injuries, were documented. The results of this chart review suggest pulsatile lavage therapy can be administered at the patient's bedside without adverse events if appropriate protocols are followed. Additional research to confirm the efficacy and effectiveness of this treatment modality in a broader subject population is warranted. PMID:23475450

    The objective of this study was to investigate the normal cytological evaluation of bronchoalveolar lavage (BAL) fluid in healthy adult ferrets (N = 12). These ferrets underwent bronchoscopy and BAL using sterile saline [1.5 mL/kg body weight (BW)]. Percentage of fluid recovered, total leukocyte count, differential leukocyte count, and cell count of the epithelial lining fluid (ELF) were determined. The mean percentage of lavage volume recovered from the right lung and left lung were 67.8 ± 14.9% and 69.7 ± 20.0%, respectively. Gender (P = 0.12) and weight (P = 0.17) did not significantly affect the mean percentage of recovered volume. The mean percentage of recovered volume (P = 0.47) and the mean leukocyte count (P = 0.17) from the right and left lung were not significantly different. Macrophages were the main leukocyte component of the lavages, followed by neutrophils, lymphocytes, and eosinophils. The mean proportion of ELF in BAL fluid was 9.3 ± 3.7% v/v. Bronchoscopy is clinically useful for collecting good quality BAL samples for cytological analysis in ferrets. The leucocyte differential was established, which may help veterinarians to make better clinical decisions when treating respiratory disease. Further studies are required with a larger group in order to establish the healthy reference intervals for BAL values in ferrets. PMID:26733735

    OBJECTIVES--Among other constituents, fuel oil ash contains vanadium pentoxide, a known respiratory irritant. Exposure to ambient vanadium pentoxide dust has been shown to produce irritation of the eyes, nose, and throat. The usefulness of nasal lavage in detecting an inflammatory response to exposure to fuel oil ash among 37 boilermakers and utility workers was investigated. METHODS--A baseline lavage was performed on the morning of the first day back to work after an average of 114 days away from work (range 36 hours to 1737 days). A lavage was performed after exposure on the morning three days after the baseline lavage. Exposure to respirable particulate matter of diameter < or = 10 microns (PM10) and respirable vanadium dust were estimated with daily work diaries and a personal sampling device for respirable particulates. These estimates were made for each subject on each workday during the three days between lavages. For each subject, the adjusted change in polymorphonuclear cells was calculated by dividing the change in polymorphonuclear cell counts by the average of the counts before and after exposure. The association between the adjusted polymorphonuclear cell counts and exposure was assessed with multiple linear regression, adjusted for age and current smoking. RESULTS--Personal sampling (one to 10 hour time weighted average) showed a range of PM10 concentrations of 50 to 4510 micrograms/m3, and respirable vanadium dust concentration of 0.10 to 139 micrograms/m3. In smokers the adjusted polymorphonuclear cell count was not significantly different from zero (-0.1%, P > 0.5), but in nonsmokers it was significantly greater than zero (+50%, P < 0.05). In both non-smokers and smokers, there was considerable variability in adjusted polymorphonuclear cell counts and a dose-response relation between these adjusted cell counts and either PM10 or respirable vanadium dust exposure could not be found. CONCLUSION--A significant increase in polymorphonuclear cells in

    The human uterine cervix undergoes extensive changes during pregnancy. Collagen is reorganized and consolidated early in gestation with proliferation and hyperplasia of the cellular component. As term approaches, multiple factors work together in complex interactions that cause collagen dispersion and the cervix to ripen (clinically become softer). Increases in decorin levels, hyaluronic acid, and physiologic cell death are in part responsible for this remodeling process. As the collagen bundles disperse and lose strength, cytokines, hyaluronic acid, collagenases, and elastase possibly work together to allow effacement. Then, the mechanical forces of uterine contractions extend the elastin and allow dilatation. During dilation, levels of cytokines and hyaluronic acid begin to decrease, which may serve to decrease collagenolytic activity and allow the cervix to begin the process of repairing itself. Despite this advance knowledge of cervical ripening, the signals responsible for the initiation of these changes remain to be elucidated. If we can understand the exact mechanisms that affect these changes, then we may be better able to address such complex issues as cervical incompetence, preterm delivery, postterm delivery, and proper "ripening" of the cervix to avoid surgical delivery for arrest disorders of the active phase.

    To assess the capability of magnetic resonance (MR) imaging to demonstrate postirradiation changes in the uterus, MR studies of 23 patients who had undergone radiation therapy were retrospectively examined and compared with those of 30 patients who had not undergone radiation therapy. MR findings were correlated with posthysterectomy histologic findings. In premenopausal women, radiation therapy induced (a) a decrease in uterine size demonstrable as early as 3 months after therapy ended; (b) a decrease in signal intensity of the myometrium on T2-predominant MR images, reflecting a significant decrease in T2 relaxation time, demonstrable as early as 1 month after therapy; (c) a decrease in thickness and signal intensity of the endometrium demonstrable on T2-predominant images 6 months after therapy; and (d) loss of uterine zonal anatomy as early as 3 months after therapy. In postmenopausal women, irradiation did not significantly alter the MR imaging appearance of the uterus. These postirradiation MR changes in both the premenopausal and postmenopausal uteri appeared similar to the changes ordinarily seen on MR images of the nonirradiated postmenopausal uterus.

    Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples with a material with known thermal conductivity, is described. Measurements were conducted on tissue samples from eleven patients, directly after hysterectomy. Samples with and without endometrium, as well as coagulated samples, were examined. The thermal conductivity of myometrial tissue was found to be 0.536 +/- 0.012 W m(-1) K(-1) (mean +/- 1 SD) and the corresponding water content was 81.2 +/- 1.5% (mean +/- 1 SD). Measurements on samples with both endometrium and myometrium showed similar thermal conductivity (0.542 +/- 0.008 W m(-1) K(-1), mean +/- 1 SD) and water content (81.6 +/- 0.7%, mean +/- 1 SD). It was also indicated that coagulation causes dehydration, resulting in a lower thermal conductivity. PMID:9725614

    There are two main types of uterine cancer. Endometrial carcinoma, the most commonly diagnosed genital cancer in women, accounts for most cases (more than 95%) and sarcoma comprises the remainder. Endometrial cancer primarily occurs in postmenopausal women. Risk factors include exposure to high levels of endogenous estrogen (eg, obesity, nulliparity, late menopause) or exogenous estrogen (eg, hormone replacement therapy, tamoxifen) and pelvic radiation. Genetics are involved in a small percentage of cases, notably among women in families with hereditary nonpolyposis colorectal cancer (HNPCC). More than 80% of patients with endometrial cancers present with abnormal uterine bleeding. Endometrial biopsy and transvaginal ultrasound are the first-line tests to evaluate bleeding. If the endometrial lining is thickened on ultrasound, endometrial biopsy is indicated. If symptoms persist after negative biopsy results, or if biopsy results are inadequate, hysteroscopy is performed for tissue sampling. Most patients with endometrial cancer are diagnosed early, when cancer is confined to the uterus. Hysterectomy is the treatment of choice in such cases. Treatment of advanced disease involves radiotherapy and/or chemotherapy. Perimenopausal women should be informed that abnormal bleeding could be a sign of cancer and should be evaluated. However, no routine screening is recommended except for women with HNPCC. PMID:26569046

    A unicornuate uterus with a rudimentary horn is a uterine anomaly resulting from the incomplete development of one of the Müllerian ducts and an incomplete fusion with the contralateral side. Pregnancy in a rudimentary horn of the uterus is a rare clinical condition with a reported incidence of 1 in 100,000 to 140,000 pregnancies. Usually the diagnosis is missed and may present as an emergency with haemoperitoneum. The standard treatment is the surgical excision of the horn. A gravida 2, para 1 patient presented at 23 weeks’ gestation with fetal demise. Repeated failed attempts at induction of labour raised the suspicion of an abnormally located pregnancy which was confirmed by magnetic resonance imaging. She underwent a laparotomy with right rudimentary horn excision. The final diagnosis of a non-communicating rudimentary horn pregnancy was made intraoperatively and was confirmed by histopathology. This case highlights the importance of an early ultrasound in detecting uterine anomalies and the need for high clinical suspicion. PMID:24516746

    Most rhinovirus serotypes use intercellular adhesion molecule-1 (ICAM-1) as the receptor to enter cells, but ICAM-1 expression has not been detected on normal nasal epithelial cells. During experimental rhinovirus infection, expression of ICAM-1 on nasal epithelial cells was examined with immunohistochemical staining of nasal scrape biopsy specimens, and levels of soluble ICAM-1 in nasal lavage fluid were measured by sandwich enzyme-linked immunosorbent assay technique. Expression of ICAM-1 on nasal epithelial cells increased following inoculation in 20 of 23 infected subjects. The median number of ICAM-1-positive cells per 6.25-mm(2) area of stained biopsy specimen was 0 in control samples (day 20 or 33 after inoculation), and in those without infection, 6 on day 1 (P< or =.05), 14.5 on day 3 (P< or =.01), 1.5 on day 5, and 0 on day 9. In a different group of volunteers, soluble ICAM-1 in nasal lavage fluid was higher on days 1 and 3 compared with preinoculation levels (P< or =.001), but only 11 of 23 infected subjects had a 2-fold or greater increase. Up-regulation of ICAM-1 receptor expression on nasal epithelial cells occurred within 24 hours after inoculation in experimental rhinovirus infections (prior to onset of symptoms) and declined promptly by day 5.

    Cinnamon is a spice used by some populations as a traditional remedy to control blood pressure and thus hypertension. Cinnamon extract decreases contractility in some smooth muscles, but its effect on uterine smooth muscle is unknown. The aim of this study was to determine the physiological and pharmacological effects of cinnamon extract (CE) on the contractions of isolated rat uterine strips and to investigate its possible mechanism of action. Isolated longitudinal uterine strips were dissected from non-pregnant rats, mounted vertically in an organ bath chamber, and exposed to different concentrations of CE (10-20mg/mL). The effect of CE was investigated in the presence of each of the following solutions: 60mM KCl, 5nM oxytocin, and 1μM Bay K8644. CE significantly decreased the force of uterine contraction in a concentration-dependent manner and significantly attenuated the uterine contractions elicited by KCl and oxytocin. In addition, CE significantly decreased the contractile force elicited when L-type Ca(2+) channels were activated by Bay K8644. CE's major mechanism may be inhibition of L-type Ca(2+) channels, which limits calcium influx. These data demonstrate that CE can be a potent tocolytic that can decrease uterine activity regardless of how the force was produced, even when the uterus was stimulated by agonists. As a result, cinnamon may be used to alleviate menstrual pain associated with dysmenorrhoea or prevent unwanted uterine activity in early pregnancy. PMID:26952750

    Bronchoalveolar lavage (BAL) partially recovers both the instilled saline and the alveolar fluid, so-called epithelial lining fluid (ELF), but a correction for the dilution due to the BAL technique itself is needed to know the amount of recovered ELF. In this regard, urea nitrogen may be useful and has been proposed to calculate ELF. The aim of the present study was to develop and validate a new method to measure urea nitrogen in BAL fluid (BALF). We used 19 BALF samples obtained from neonates and infants with different respiratory conditions. The urea nitrogen assay was carried out on Cobas c311 analyzer (Roche Diagnostics). A validation study shows that the method is perfectly linear (R(2) = 0.999), sensitive (limit of detection = 0.055 mg/dL; limit of quantification = 0.16 mg/dL), repeatable (low = 0.15 ± 0.02, 13.3%; high = 1.80 ± 0.02, 1.1%), reproducible (low = 0.14 ± 0.02, 14.2 %; high = 1.76 ± 0.04, 2.2 %) with accuracy ranging between 93-96%. Our results support the robustness of validated procedure since the described method appears simple, precise, rapid, and suitable for routine analysis. Thus, it may be used to correct concentration of various noncellular BAL components and calculate their ELF amounts in neonates and infants. PMID:25586999

    The authors review aberrations of uterine anatomy and physiology affecting pregnancy outcomes with IVF. In the case of endometriosis and hydrosalpinx, pathologies outside of the uterus alter the uterine endometrium. In the case of endometriosis, Dominique de Ziegler outlines the numerous changes in gene expression and the central role of inflammation in causing progesterone resistance. With endometriosis, the absence of ovarian function inherent in deferred transfer, with or without a more lengthy suppression of ovarian function, appears to be sufficient to restore normal function of eutopic endometrium. Because laparoscopy is no longer routine in the evaluation of infertility, unrecognized endometriosis then becomes irrelevant in the context of assisted reproductive technology. With hydrosalpinx and submucus myomas, the implantation factor HOXA-10 is suppressed in the endometrium and, with myomas, even in areas of the uterus not directly affected. Daniela Galliano reviews various uterine pathologies, the most enigmatic being adenomyosis, where the endometrium also manifests many of the changes seen in endometriosis and deferred transfer with extended suppression appears to provide the best outcomes. Ettore Cicinelli's group has extensively studied the diagnosis and treatment of endometritis, and although more definitive diagnosis and care of this covert disorder may await techniques such as sequencing of the endometrial microbiome, it undoubtedly is an important factor in implantation failure, deserving our attention and treatment.

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    Uterine inversion is shortly described as the indentation and depression of the fundic area extending downwards up to the different levels of the birth canal till vaginal opening. Clinical diagnosis of uterine inversion is difficult due to its non-specific symptoms and physical examination. Ultrasonography is the most practical modality for radiological evaluation, but it is inadequate to determine the exact nature of this condition and making the differential diagnosis. In this case, we present the main MRI findings of non-puerperal complete uterine inversion caused by a giant leiomyoma. PMID:26715983

    Uterine fibroids are the most common benign uterine tumors in women of reproductive age. Although most women are asymptomatic (80%), fibroids, according to their type and location, can cause several symptoms and impact quality of life. To date, no medical treatment is able to eliminate fibroids. Ulipristal acetate (UPA) is an orally active synthetic selective progesterone receptor modulator (SPRM) characterized by a tissue-specific progesterone antagonist effect that reduces the proliferation of leiomyoma cells and induces apoptosis. It was licensed in Europe for preoperative fibroid treatment in 2012. Its pharmacological and pharmacodynamic characteristics, its efficacy and good tolerance make UPA a new important tool in the management of uterine fibroids. PMID:26744741

    Uterine rupture is one of the most feared obstetric complications affecting the pregnant woman and fetus. Most of the cases have various risk factors and mainly occur during the second or third trimester. However, spontaneous uterine rupture during the first trimester is extremely rare. We experienced a case of spontaneous uterine rupture in a 36-yr-old multiparous woman without definite risk factors. The initial impression was a hemoperitoneum of an unknown origin with normal early pregnancy. Intensive surgical method would be needed for accurate diagnosis and immediate management in bad situation by hemoperitoneum even though a patient was early pregnancy. PMID:16361828

    Summary Purpose: to evaluate the short and long term effectiveness of ultrasonography (US)-guided percutaneous needle lavage in calcific tendinopathy of the rotator cuff. To study the evolution of the size of calcifications and pain in the two years after treatment. Methods: a 2 year longitudinal prospective study is carried out after applying the UGPL technique on a number of patients diagnosed with calcific tendinitis of the rotator cuff. Clinical, ultrasound and radiology follow-up controls were performed, 3 months, 6 months, one year and two years after the treatment. The Visual Analog Scale (VAS) was used to assess the pain. The degree and point of pain is selected on a 10cm line, arranged horizontally or vertically. The “0” represents no pain and “10” represents worst pain. The population studied was made up of 121 patients that required our service as a result of suffering from a painful shoulder. Results: the pain (VAS) and the size of the calcification significantly decreased with the application of the technique (p< 0,001 in both cases) and regardless of the sex (p: 0.384 for pain and p: 0.578 for the size of the calcification). This occurred from the first check-up (3 months) and was maintained for two year. Conclusion: we consider this technique to be a valid alternative as a first-choice treatment of calcific tendinitis of the shoulder. The intervention is simple, cost-effective, does not require hospitalization, involves no complications, rehabilitation treatment is not required and it shows very few side effects without sequelae, significantly reducing the size of the calcification and pain in the majority of patients.

    Twenty-two samples, taken from eight pathological proved uterine myoma patients, were embedded in paraffin and cut into slices of identical thickness (4.0 μm). After deparaffinization, washing and drying, the slices of myomal tissue and their neighboring myometrial tissue were bombarded by 2.0 MeV proton beams from a 3 MV Van de Graaff accelerator. The induced characteristic X-rays were then detected and analyzed using a HPGe detector system. The absolute concentrations of trace elements contained in tumors and normal tissues of human myomal uterus were determined, in reference to a known concentration of doped yttrium. Significant correlations between the concentration of elements, both in tumors and in normal tissues, were found.

    Pregnancy in a non-communicating rudimentary horn is an extremely rare form of ectopic gestation. The rudimentary horn may or may not communicate with the uterine cavity with the majority of cases being non-communicating. The patient exhibits features of acute abdomen and carries a high risk of maternal death. Even modern scans remain elusive whereas laparatomy remains the confirmatory procedure for the diagnosis. Because of the varied muscular constitution in the thickness and distensibility of the wall of the rudimentary horn, pregnancy is accommodated for a variable period of gestation. Here, we report three cases of pregnancy in a non-communicating rudimentary horn of the uterus in different periods of gestation, their outcome and a review of the available literature.

    In September 2014, a healthy male child was born in Sweden following a successful uterine transplantation (UTx). The event brought hope to many women without functional uteruses around the world. Having a child with a transplanted uterus is now possible, and as knowledge of the procedure proliferates and interest in UTx grows, it is important to begin thinking about how a scarce supply of uteruses will be allocated. This article represents a first discussion of the range of factors that must be considered in answering the allocation question. The primary issues addressed are (1) the motivation to seek treatment, (2) allocation by age, (3) child-rearing capacity, and (4) the amount of infertility treatment required. A set of eligibility and ranking criteria are presented. These criteria are not exhaustive but are intended to spark discussion about how uteruses can be allocated in a just manner. PMID:26864991

    Rhabdomyosarcoma arising in the female genital tract carries five-year survival in excess of 80%, but lifelong infertility may be a consequence of local control strategies. We present the technique and outcome for a fertility-sparing, radical abdominal trachelectomy in a 12-year-old girl with anaplastic, embryonal rhabdomyosarcoma involving the uterine cervix. The patient had presented to our center following the piecemeal resection of a uterine cervical mass; because of concern about microscopic residual disease, we classified her as group II-A according to the International Rhabdomyosarcoma Study (IRS) system. Staging studies excluded the presence of distant disease. The patient received four cycles of multiagent chemotherapy and then underwent radical abdominal trachelectomy, with removal of the uterine cervix, parametria, vaginal cuff, and regional lymph nodes. Microscopically, the specimen showed treatment effect and no residual tumor. Regional nodes were negative. Radical abdominal trachelectomy, which has not been previously reported for rhabdomyosarcoma, has appeared to secure local disease control in this case, while preserving the patient’s future fertility potential. In properly selected cases of rhabdomyosarcoma of the uterine cervix, where involvement of the uterus proper is not present, radical abdominal trachelectomy may be an attractive fertility-sparing alternative to radical hysterectomy.

    The authors present an exceptional case of a transitional cell carcinoma of the uterine tube in a 59-year-old female patient, co-existing with appendicitis. Originally, the patient was assigned to surgery due to an inflamed tumour of the right adnexa. A mid-surgery diagnose revealed appendicitis by chance, but in the course of an examination of the right uterine tube, performed on the spot, no progressive carcinoid process was univocally diagnosed. Therefore, the treatments applied were a bilateral salpingectomy and appendectomy. In the course of the final pathomorphological examination, using an immunohistochemical technique, a primary cancer of the uterine tube composed of transitional epithelium cells (transitional cell carcinoma G-2, pT1a) was diagnosed. At the time of the second surgery, a radical hysterectomy, bilateral oophorectomy and omentectomy were performed and afterwards, the patient was treated with a post-operational radiotherapy. The authors support the thesis that a primary cancer of the uterine tube may, as it looks, suggest a different ailment and present diagnostic problems. PMID:16200402

    Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples with a material with known thermal conductivity, is described. Measurements were conducted on tissue samples from eleven patients, directly after hysterectomy. Samples with and without endometrium, as well as coagulated samples, were examined. The thermal conductivity of myometrial tissue was found to be and the corresponding water content was % . Measurements on samples with both endometrium and myometrium showed similar thermal conductivity (, ) and water content (%, ). It was also indicated that coagulation causes dehydration, resulting in a lower thermal conductivity.

    Patient: Female, 60 Final Diagnosis: UPSC with adrenal metastasis Symptoms: Post menopausal bleeding Medication: — Clinical Procedure: Adrenalectomy Specialty: Oncology Objective: Rare disease Background: Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. Case Report: A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. Conclusions: UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    Bonchoalveolar lavage is a safe and poorly invasive tool with a great diagnostic value particularly in diffuse infiltrative pulmonary diseases (IPD). In specific instances, it allows for a definite diagnosis (alveolar hemorrhage; alveolar proteinosis, lipidoses, infiltrative malignant diseases, opportunistic infections), obviating the need to perform more invasive diagnostic procedures like video-assisted surgical biopsy. In inflammatory IPD, either idiopathic, diagnostic or associated with inhaled antigens or with collagen vascular diseases for instance, it represents a crucial orientation diagnostic tool, considerably narrowing the spectrum of potential differential diagnosis.

    In acute periprosthetic infection, irrigation and debridement with component retention has a high failure rate in some studies. We hypothesize that pulse lavage irrigation is ineffective at removing biofilm from total knee arthroplasty (TKA) components. Staphylococcus aureus biofilm mass and location was directly visualized on arthroplasty materials with a photon collection camera and laser scanning confocal microscopy. There was a substantial reduction in biofilm signal intensity, but the reduction was less than a ten-fold decrease. This suggests that irrigation needs to be further improved for the removal of biofilm mass below the necessary bioburden level to prevent recurrence of acute infection in total knee arthroplasty.

    Recent advances in assisted reproductive technology (ART) have made it possible to circumvent many causes of male and female infertility. The right to have a child by ART has been respected for infertile couples. However, there are currently no legal regulations concerning ART in Japan, and this has resulted in social and ethical problems. Surrogacy involves particularly complex medical, ethical, social, and legal issues, and is frequently focused on as a major social concern. Uterine transplantation (UTx) is a potential alternative for young women with uterine factor infertility due to hysterectomy for treatment of a malignant uterine tumor or massive blood loss after delivery, or because of a congenital disease such as Mayer-Rokitansky-Küster syndrome. UTx has been examined in experimental animals as a basis for establishment of fecundity for young women with uterine factor infertility. In this review, we focus on surrogacy in Japan and UTx research, and discuss the current status and concerns in this field. PMID:21632170

    A 44-year-old nulliparous woman was transferred to a tertiary obstetric hospital for investigation of acute onset abdominal pain. She was at gestation of 32 weeks and 2 days with a history of previous laparoscopic fundal myomectomy. An initial bedside ultrasound demonstrated oligohydramnios. Following an episode of increased pain early the following morning, a formal ultrasound diagnosed a uterine rupture with the fetal arm extending through a uterine rent. An uncomplicated classical caesarean section was performed and the neonate was delivered in good condition but with a bruised and oedematous right arm. The neonate was transferred to the Special Care Nursery for neonatal care. The patient had an uncomplicated postoperative course and was discharged home three days following delivery. This is an unusual presentation of uterine rupture following myomectomy where the fetal arm had protruded through the uterine wall. PMID:26925275

    Postpartum uterine infections reduce reproductive efficiency and have significant animal welfare and economic consequences. Postpartum uterine infections are classified as nonspecific, but Arcanobacterium pyogenes and Escherichia coli are usually associated with them in cattle and sheep. Pyometra is the most common type of uterine infection in dairy cattle, and it is detected almost exclusively in cows with active corpora lutea. Luteal progesterone typically down-regulates uterine immune functions and prevents the uterus from resisting infections. Progesterone also can down-regulate uterine eicosanoid synthesis. This seems to be a critical event in the onset of uterine infections, because eicosanoids can up-regulate immune cell functions in vitro. In addition, exogenous prostaglandin F2 alpha stimulates uterine secretion of prostaglandin F2 alpha and enhances immune functions in vivo. Thus, one may hypothesize that eicosanoids can override the negative effects of progesterone and that the up-regulatory effects of exogenous prostaglandin F2 alpha allow the uterus to resolve an infection, regardless of progesterone concentrations. Based on the results of studies to test that hypothesis, cows, sheep, and pigs in various physiological statuses are resistant to intrauterine infusions of Arcanobacterium pyogenes and Escherichia coli, unless progesterone concentrations are increased. In sheep and pigs, exogenous prostaglandin F2 alpha stimulates uterine production of prostaglandin F2 alpha and allows the uterus to resolve Arcanobacterium pyogenes-Escherichia coli-induced infections, even when progesterone is maintained at luteal phase concentrations before and after treatment. Prostaglandin F2 alpha is a proinflammatory molecule that stimulates the production of various proinflammatory cytokines, and it may enhance uterine production of leukotriene B4. Proinflammatory cytokines and leukotriene B4 enhance phagocytosis and lymphocyte functions. Even though there are clear

    Differential diagnosis of uterine leiomyomas and leiomyosarcomas is needed to determine whether the uterus can be retained. Therefore, biomarkers for uterine leiomyomas, and reliable and objective diagnostic methods have been desired besides the pathological diagnosis. In the present study, we identified 12 genes specific to uterine leiomyomas based on DNA methylation. Using these marker genes specific to uterine leiomyomas, we established a hierarchical clustering system based on the DNA methylation level of the marker genes, which could completely differentiate between uterine leiomyomas and normal myometrium. Furthermore, our hierarchical clustering system completely discriminated uterine cancers and differentiated between uterine leiomyosarcomas and leiomyomas with more than 70% accuracy. In conclusion, this study identified DNA methylation-based marker genes specific to uterine leiomyomas, and our hierarchical clustering system using these marker genes was useful for differential diagnosis of uterine leiomyomas and leiomyosarcomas.

    For use in an epidemiologic study of subsequent tumors, absorbed doses from brachytherapy and external beam radiotherapy were measured and calculated for various tissues of patients treated for cancer of the uterine cervix. External beams included orthovoltage x rays (1.9 and 3.0 mm Cu half-value layer), cobalt-60 gamma rays, 2 MV x rays, and 25 MV x rays. The brachytherapy sources were encapsulated radium. Measurements were made in an Alderson anthropomorphic phantom and a water phantom; calculations were made using a Monte Carlo technique or standard radiotherapy methods. Depending upon stage of disease and radiation energy, the absorbed doses (cGy) from typical treatment regimes to tissues of interest were: ovaries, 1400--5200; stomach, 130--320; kidneys, 120--310; pancreas, 100--260; lungs, 22--48; breasts, 19--52; thyroid, 6--17; salivary glands, 4--11; brain, 2--7, and total active bone marrow, 320--1100. The lower values of each range were for stage I of the disease.

    A framework has been investigated to enable a variety of comparative studies in the context of needle-based gynaecological brachytherapy. Our aim was to create an anthropomorphic phantom-based platform. The three main elements of the platform are the organ model, needle guide, and needle drive. These have been studied and designed to replicate the close environment of brachytherapy treatment for cervical cancer. Key features were created with the help of collaborating interventional radio-oncologists and the observations made in the operating room. A phantom box, representing the uterus model, has been developed considering available surgical analogies and operational limitations, such as organs at risk. A modular phantom-based platform has been designed and prototyped with the capability of providing various boundary conditions for the target organ. By mimicking the female pelvic floor, this framework has been used to compare a variety of needle insertion techniques and configurations for cervical and uterine interventions. The results showed that the proposed methodology is useful for the investigation of quantifiable experiments in the intraabdominal and pelvic regions.

    Of a group of 30 clinically normal male Holstein calves two to eight weeks of age, six two week old and six four week old calves met various radiographical and clinicopathological criteria for normality. Bronchoalveolar lavage was performed by fiberoptic bronchoscopy on cranial and caudal lung regions in all 30 calves and samples analyzed for free cells, microorganisms, and immunoglobulins. Lateral chest radiographs and lung biopsies were also conducted on each calf. Calves were euthanized and necropsied ten days after bronchoalveolar lavage was conducted. Reported in this paper are results from the 12 normal calves. Microorganisms were present in small numbers in the lower respiratory tract of some normal calves. There were no differences in the above parameters between cranial and caudal lobes. There were statistically significant changes in bronchoalveolar lavage cell proportions with age although there were no detectable differences in clinical signs. Four week old calves had a lower percentage of macrophages and a higher percentage of epithelial cells than two week old animals (p less than 0.05). There was also a trend toward an increased percentage of neutrophils in older calves but this was not significant (p greater than 0.05). Total bronchoalveolar lavage protein also appeared to increase with age (p less than 0.05). In both groups a higher proportion of IgG2 in bronchoalveolar lavage compared to serum was found, suggesting the presence of a local selective transfer mechanism into respiratory secretions.

    A 1968 Indian study compared the effect of Norlutin (17-alpha ethynl 19-nor testosterone) and Provera (6-methyl acetoxyprogesterone) suspensions on the uterine motility of virgin rats and mice to the action of natural progesterone and testosterone. The test animals were spayed and 2 weeks later, the rats were injected with 2 mcg of estradiol benzoate daily for 3 consecutive days. The mice received .2 mcg injections. On day 4 the animals were sacrificed and the uterine horns were suspended in a 40 ml organ bath containing Tyrode solution at 32 degrees centigrade and aerated with 5% carbon dioxide in oxygen. Rat uterine movement was recorded isotonically with a linear frontal writing lever while a heart lever was used for mice. The action of the compounds was also tested on oxytocin-induced spasms. Norlutin suspension (1.25-50 mcg/ml) inhibited both amplitude and tone of uterine contraction within 2-10 minutes and lasted more than 1 hour. The uterus failed to respond to oxytocin during peak Norlutin action. A progesterone concentration of 1.25 mcg also produced uterine relaxation but its effect on contractual tone was insignificant. Graded concentrations of Provera and testosterone suspension failed to effect uterine motility in rats and mice. PMID:5784655

    The window of implantation is defined by the inhibition of uterine epithelial proliferation, structural epithelial cell remodeling, and attenuated estrogen (E2) response. These changes occur via paracrine signaling between the uterine epithelium and stroma. Because implantation defects are a major cause of infertility in women, identifying these signaling pathways will improve infertility interventions. Bone morphogenetic proteins (BMPs) are TGF-β family members that regulate the postimplantation and midgestation stages of pregnancy. In this study, we discovered that signaling via activin-like kinase 3 (ALK3/BMPR1A), a BMP type 1 receptor, is necessary for blastocyst attachment. Conditional knockout (cKO) of ALK3 in the uterus was obtained by producing Alk3flox/flox-Pgr-cre–positive females. Alk3 cKO mice are sterile and have defects in the luminal uterine epithelium, including increased microvilli density and maintenance of apical cell polarity. Moreover, Alk3 cKO mice exhibit an elevated uterine E2 response and unopposed epithelial cell proliferation during the window of implantation. We determined that dual transcriptional regulation of Kruppel-like factor 15 (Klf15), by both the transforming growth factor β (TGF-β) transcription factor SMAD family member 4 (SMAD4) and progesterone receptor (PR), is necessary to inhibit uterine epithelial cell proliferation, a key step for embryo implantation. Our findings present a convergence of BMP and steroid hormone signaling pathways in the regulation of uterine receptivity. PMID:26721398

    Absolute uterine factor infertility (UFI) refers to the refractory causes of female infertility stemming from the anatomical or physiological inability of a uterus to sustain gestation. Today, uterine factor infertility affects 3-5% of the population. Traditionally, although surrogacy and adoption have been the only viable options for females affected by this condition, the uterine transplant is currently under investigation as a potential medical alternative for women who desire to go through the experience of pregnancy. Although animal models have shown promising results, human transplantation cases have only been described in case reports and a successful transplant leading to gestation is yet to occur in humans. Notwithstanding the intricate medical and scientific complexities that a uterine transplant places on the medical minds of our time, ethical questions on this matter pose a similar, if not greater, challenge. In light of these facts, this article attempts to present the ethical issues in the context of experimentation and standard practice which surround this controversial and potentially paradigm-altering procedure; and given these, introduces "The Montreal Criteria for the Ethical Feasibility of Uterine Transplantation", a set of proposed criteria required for a woman to be ethically considered a candidate for uterine transplantation.

    Asbestos body (AB) concentrations in bronchoalveolar lavage samples of 15 brake lining (BL) workers exposed only to chrysotile have been determined and compared with those from 44 asbestos cement (AC) workers extensively exposed to amphiboles. The mean AB concentrations (263 +/- 802 and 842 +/- 2086 AB/ml respectively) for those groups did not differ significantly but were much higher than those found in control groups. Analytical electron microscopy of asbestos body cores showed that in the BL group 95.6% were chrysotile fibres whereas in the AC group amphiboles accounted for 93.1%. The size characteristics of the central fibres differed for chrysotile and amphibole AB, the former being shorter and thinner. Examination of repeated bronchoalveolar lavage samples showed that the mechanisms of clearance of chrysotile fibres do not affect AB concentration for at least 10 months after cessation of exposure. It thus appears that routine counting of ABs in BAL allows the assessment of current or recent occupational exposures to asbestos. Exposures to chrysotile lead to AB concentrations comparable with those encountered in exposures to amphiboles. Images PMID:2155652

    We compared 14 molecular assays for their ability to detect the Mycobacterium tuberculosis complex in bronchoalveolar lavage fluid samples. Three approaches were followed. First, by using DNA from Mycobacterium bovis BCG, we determined the detection limits of the assays using routine molecular methods. Second, in order to determine the analytical sensitivities of the assays, we added one of four M. tuberculosis isolates with various numbers of the insertion sequence IS6110 to N-acetyl-l-cysteine (NALC)-NaOH-treated bronchoalveolar lavage fluid samples in dilutions of 1:10 to 1:10,000,000. Third, intertest variabilities were measured and defined by the standard deviations for the quantitation cycle (Cq) values of three positive test results per dilution per assay. The 14 assays tested had similar analytical sensitivities, except for GeneXpert, which had an analytical sensitivity that was 10- to 100-fold lower than that of the other assays. The MP MTB/NTM test and the in-house TaqMan-10 revealed the best performances for the detection limit and had the highest analytical sensitivities. Most of the tests performed well regarding detection limit and analytical sensitivity for the detection of the M. tuberculosis complex in serial dilutions, and the differences were small. The MP MTB/NTM and the in-house TaqMan-10 assays revealed the best, and GeneXpert the worst, overall performances. PMID:23966510

    An influx of neutrophils (PMNs), a primary feature of acute inflammation, has been associated with the development of lower lung disorders, such as emphysema and idiopathic fibrosis, as well as airway hyperreactivity and increased mucus secretion. It was previously established that an acute inflammatory response in the upper respiratory tract of humans could be studied by analysis of nasal lavages (NL), which is inexpensive, non-invasive, and atraumatic. However, the relationship of the cellular changes in the upper respiratory tract to changes in the lower airways has not been thoroughly investigated in humans. Here the cellular changes detected in the NL with those detected in the bronchoalveolar lavage (BAL) taken from the same individual have been compared. Ten subjects were exposed to either filtered air or 0.4 ppm ozone (O3), with exercise, for 2 hrs. The NL was done prior to, immediately following an 18 hr post exposure, while the BAL was done only at 18 hr post exposure. A significant increase in PMNs was detected in the NL immediately post exposure to 03, (7.7-fold increase; p=.003), and remained elevated in the 18 hr post-03 NL (6.1-fold increase; p<.001).

    This study aimed to investigate cytocidal effects of hypotonic shock on esophageal squamous cell carcinoma (ESCC) cell lines, and to apply pleural lavage with distilled water to surgery for ESCC. Three human ESCC cell lines, TE5, TE9 and KYSE170 were exposed to distilled water, and morphological changes in ESCC cells were closely observed under a differential interference contrast microscope connected to a high-speed digital video camera. Further, serial cell volume changes after hypotonic shock were measured using a high-resolution flow cytometer. To investigate the cytocidal effects of hypotonic shock on ESCC cells, re-incubation of ESCC cells was performed after hypotonic shock. Additionally, the effects of 5-nitro-2-(3-phenylpropylamino)-benzoic acid (NPPB), a Cl- channel blocker, during hypotonic shock were analyzed. Video recordings by high-speed digital camera demonstrated that hypotonic shock with distilled water induced cell swelling followed by cell rupture. Measurements of cell volume changes using a high-resolution flow cytometer indicated that severe hypotonicity with distilled water increased broken fragments of ESCC cells within 5 min. Re-incubation experiments demonstrated cytocidal effects of hypotonic shock on ESCC cells. Treatment of cells with NPPB increased cell volumes by the inhibition of regulatory volume decrease, which is observed during hypotonic shock, and enhanced cytocidal effects. These findings demonstrated the cytocidal effects of hypotonic shock on ESCC cells, and clearly support the efficacy of pleural lavage with distilled water during surgery for ESCC. PMID:21567108

    Secretory phospholipase A2 (sPLA2), which links surfactant catabolism and lung inflammation, is associated with lung stiffness, surfactant dysfunction, and degree of respiratory support in acute respiratory distress syndrome and in some forms of neonatal lung injury. Varespladib potently inhibits sPLA2 in animal models. The authors investigate varespladib ex vivo efficacy in different forms of neonatal lung injury. Bronchoalveolar lavage fluid was obtained from 40 neonates affected by hyaline membrane disease, infections, or meconium aspiration and divided in 4 aliquots added with increasing varespladib or saline. sPLA2 activity, proteins, and albumin were measured. Dilution was corrected with the urea ratio. Varespladib was also tested in vitro against pancreatic sPLA2 mixed with different albumin concentration. Varespladib was able to inhibit sPLA2 in the types of neonatal lung injury investigated. sPLA2 activity was reduced in hyaline membrane disease (P < .0001), infections (P = .003), and meconium aspiration (P = .04) using 40 µM varespladib; 10 µM was able to lower enzyme activity (P = .001), with an IC(50) of 87 µM. An inverse relationship existed between protein level and activity reduction (r = 0.5; P = .029). The activity reduction/protein ratio tended to be higher in hyaline membrane disease. Varespladib efficacy was higher in vitro than in lavage fluids obtained from neonates (P < .001). PMID:21602519

    Bronchial hyperresponsiveness to methacholine with asthma-like symptoms ("ski asthma") is frequent in elite cross-country skiers. To further the understanding of "ski asthma", 10 nonasthmatic, nonatopic controls and 30 adolescent elite skiers were investigated by bronchoscopy and bronchoalveolar lavage (BAL). Nine skiers were atopic without allergy symptoms. Compared with controls, the macroscopic inflammatory index in the proximal airways in skiers was three-fold greater (median (interquartile range) 3.0 (2.0-5.0) versus 1.0 (0.8-2.3), p=0.008). In the BAL fluid, skiers had significantly greater total cell (p<0.05) and percentage lymphocyte (p<0.01) and mast cell counts (p<0.05). Neutrophil and eosinophil counts were not significantly different and eosinophil cationic protein was not detected. Tumour necrosis factor-alpha and myeloperoxidase were detected in 12 (40%) and six (20%) skiers, respectively. In skiers with ski asthma, the inflammatory index was greater than in nonasthmatic skiers. Lymphocyte subtypes and activation markers, and concentration of albumin, fibronectin and hyaluronan were not different from those in controls. Cross-country skiers have a minor to moderate degree of macroscopic inflammation in the proximal airways at bronchoscopy and a bronchoalveolar lavage fluid profile which differs in several respects from healthy controls. Skiers with ski asthma tend to show even higher degrees of bronchial inflammation. PMID:10232438

    A polymerase chain reaction (PCR)-based assay was developed for the detection of Pneumocystis carinii DNA in induced sputum and bronchoscopic alveolar lavage samples. The primer pair was selected from the published sequence of the thymidylate synthase gene of P. carinii derived from infected rats. The amplified DNA fragment of 403 bp was detected by agarose gel electrophoresis and by Southern and slot blot hybridization. No positive reaction was seen with DNA from different microorganisms typically found in the respiratory tract. P. carinii DNA was demonstrated in 30 of 42 sputum samples from immunosuppressed patients, whereas 21 of 42 sputum samples were positive by indirect immunofluorescence (IFL). Among the 42 patients, 14 were receiving prophylactic chemotherapy. In that group, PCR detected P. carinii in nine sputum samples, whereas IFL detected P. carinii in only four sputum samples. A positive PCR result was also seen in 5 of 43 IFL-negative bronchoscopic alveolar lavage samples from patients with respiratory symptoms. The PCR assay detected 10 copies of the target DNA, which corresponds to 10(-18) g of the specific P. carinii sequence. The results indicate that PCR amplification in combination with DNA hybridization is specific and is a more sensitive diagnostic method than IFL for the detection of P. carinii. Images PMID:8432806

    Goats in the tropics are often reared under the traditional extensive and semi-intensive management systems. These and other factors influence the pattern of pneumonia complex in goats. We investigated the bronchoalveolar lavage fluid (BALf) cellular changes and haematological response in different types of caprine pneumonia in Nigeria. Haematological indices and BALf cells were analysed from 300 goats randomly selected from 700 goats comprising different breed, age and body scores. The pneumonia status was well characterised using standard pathological tools. Data is summarized as Mean ± SEM and compared using non-parametric statistics at 5% significance. There was leukocytosis in the pneumonic animals. The overall lavage recovery rate was 55.5%. The differences in Haemoglobin concentration, and Lymphocyte-Neutrophil ratio were significant (p<0.05). BALf changes in the neutrophil, macrophage and eosinophil counts were significantly different (p<0.05). The diagnostic features including increased percentage neutrophils, Macrophage-Neutrophil ratio and eosinophils observed in BAL were reliable and also correlated positively to the pathological findings. BAL should be considered a component of the diagnostic approach to caprine pneumonia complex, as it may accurately aid diagnosis and identification of the causal organisms. PMID:27574761

    The purpose of this study was to determine if in vivo ozone exposure results in elevations in the levels of glutathione and glutathione-dependent enzymes in cells derived from bronchoalveolar lavage fluid (BALF). Our hypothesis was that, as part of a defense mechanism against oxygen toxicity, such cells would have increased levels of glutathione (GSH) in response to an oxidant stress. Female F344/N rats were exposed to 0.8 ppm ozone, 6 hr/day, for 1, 3, or 7 days, after which cells were collected by lung lavage. The GSH and GSH-peroxidase activity per milligram of protein in the cellular fraction, both necessary for reducing cellular peroxides, were elevated after 3 days of ozone exposure. After 7 days of exposure, cellular GSH had returned to control values, but the activity of glutathione reductase, the enzyme that reduces oxidized glutathione to GSH, was increased. Extracellular GSH concentration and glutathione reductase activity in BALF were also increased after 7 days of exposure. The total glutathione equivalents (GSH and GSSG, both cellular and extracellular) in BALF increased throughout the 7-day exposure, with GSH increasing first in the cells, and then in the extracellular fluid. This study demonstrated that the glutathione anti-oxidant system of BALF cells is stimulated by exposure to ozone. This response may serve to protect cells from the toxic effects of oxidant stress.

    Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by intra-alveolar accumulation of lipid and proteinaceous material. While a small subset of patients with PAP spontaneously improve or even undergo disease remission, the majority of patients develop persistent or progressive disease. Numerous therapies have been used to treat PAP over the years; however, at present, whole lung lavage (WLL) remains the gold standard treatment for PAP. In the present study, data were accumulated from a cohort of patients with PAP (n=11) between 2003 and 2011 at the Wuxi People’s Hospital Affiliated to Nanjing Medical University. The disease affected males and females with a ratio of 2.7:1 and all the males were current or previous smokers. The disease severity score (DSS) of the patients was mainly distributed in DSS 4 or DSS 5. All the patients underwent WLL at least once, with one patient undergoing WLLs twice and another patient three times. The clinical features, arterial blood gas and pulmonary function of the patients, were assessed prior to and following the lavage. WLL resulted in a significant improvement in symptoms, radiographic features, PaO2, D(A-a)O2 and DLCO in patients with PAP, while pulmonary ventilation function did not significantly improve. WLL appears to be an effective approach for the treatment of PAP and leads to an improvement in survival rate. PMID:25120596

    Objective: To determine reproductive outcome after in-vitro fertilization/embryo transfer (IVF-ET) in women with primary infertility following hysteroscopic septoplasty of incomplete uterine septum or arcuate uterine anomaly. Methods: This is a historical cohort study. The study group consisted of 156 consecutive patients who underwent a total of 221 cycles of IVF/ET following hysteroscopic septoplasty of an incomplete uterine septum or arcuate anomaly (Group 1). The control group included 196 consecutive patients with normal endometrial cavity on hysteroscopy who underwent a total of 369 cycles of IVF/ET (Group 2). The reproductive outcome after the first cycle of IVF-ET and the best reproductive outcome of all the cycles the patient underwent were calculated. In addition, we compared the reproductive outcome in the study group based on the type of the anomalies (septum versus arcuate). Results: In the first fresh cycle, following septoplasty, there were significantly higher clinical pregnancy and delivery rates in Group 1 (60.3% and 51.3% respectively) compared to Group 2 (38.8% and 33.2% respectively). However, there was no significant difference between the two groups in the clinical pregnancy (74.4% vs. 67.3%) or in the delivery (65.4% vs. 60.2%) rates per patient, respectively. There was no significant difference in the reproductive outcome after IVF-ET between patients who previously had arcuate uterine anomaly versus incomplete uterine septum. Conclusion: Reproductive outcome of IVF-ET after hysteroscopic correction of incomplete uterine septum/arcuate uterine anomaly in women with primary infertility is no different from women with normal uterine cavity.

    Purpose: A recently described method to produce MRI-based temperature images from individual phase maps (referenceless thermometry) was tested in images acquired during MRI-guided focused ultrasound surgery of uterine fibroids. Methods: Temperature measurements, noise in unheated areas, and thermal dose contours from 100 sonications as measured by the referenceless method were compared to images constructed with the standard phase-difference technique. Results: The agreement between temperature measurements was good, with 92% having a difference from the phase difference method less than or equal to 3°C. Conclusions: The referenceless method appears to be adequate for temperature monitoring of MRI-guided focused ultrasound in fibroids.

    After parturition, uterine bacterial infections lead to inflammatory processes such as subclinical/clinical endometritis with high prevalence in dairy cows. Endometrial epithelial cells participate in this immune response with the production of pro-inflammatory factors. The objective of the present study was to evaluate the endometrial mRNA expression pattern of pro-inflammatory factors during a selected postpartum (pp) period. Dairy cows with three different uterine health conditions on days 24-30 pp (healthy: n = 11, subclinical endometritis: n = 10, clinical endometritis: n = 10) were sampled using the cytobrush technique. Subsequently, each cow was sampled 3 more times in weekly intervals (days 31-37 pp; days 38-44 pp; days 45-51 pp). Samples were subjected to mRNA analysis performed by RT-qPCR. Additionally, an analysis of cultivable bacteria was performed at the early/late stage of the selected puerperal period. mRNA expression of 16 candidate genes was analyzed by using two different approaches. The first approach referred to the initial grouping on days 24-30 pp to reveal long-term effects of the uterine health on the subsequent puerperal period. The second approach considered the current uterine health status at each sampling to elucidate the impact of different points in time. Long-term effects seem to appear for chemokines, prostacyclin synthase and prostaglandin D2 synthase. If related to the current uterine health, the majority of candidate genes were significantly higher expressed in endometritic cows on days 45-51 pp in contrast to earlier stages of the puerperium. Microbiological analysis revealed the significantly higher prevalence of Trueperella pyogenes findings in cows with clinical endometritis on days 24-30 pp, but no correlations were found on days 45-51 pp. In conclusion, a strong immune response to subclinical/clinical endometritis in the late puerperium may be related to the negative impact of these conditions on reproductive performance

    Purpose: To compare outcomes of two different types of occlusive therapy of uterine fibroids. Methods: Women with fibroid(s) unsuitable for laparoscopic myomectomy (LM) were treated with uterine artery embolization (UAE) or laparoscopic uterine artery occlusion (LUAO). Results: Before the procedure, patients treated with UAE (n = 100) had a dominant fibroid greater in size (68 vs. 48 mm) and a mean age lower (33.1 vs. 34.9 years) than surgically treated patients (n = 100). After 6 months, mean shrinkage of fibroid volume was 53 % after UAE and 39 % after LUAO (p = 0.063); 82 % of women after UAE, but only 23 % after LUAO, had complete myoma infarction (p = 0.001). Women treated with UAE had more complications (31 vs. 11 cases, p = 0.006) and greater incidence of hysteroscopically verified intrauterine necrosis (31 vs. 3 %, p = 0.001). Both groups were comparable in markers of ovarian functions and number of nonelective reinterventions. The groups did not differ in pregnancy (69 % after UAE vs. 67 % after LUAO), delivery (50 vs. 46 %), or abortion (34 vs. 33 %) rates. The mean birth weight of neonates was greater (3270 vs. 2768 g, p = 0.013) and the incidence of intrauterine growth restriction lower (13 vs. 38 %, p = 0.046) in post-UAE patients. Conclusion: Both methods are effective in the treatment of women with future reproductive plans and fibroids not suitable for LM. UAE is more effective in causing complete ischemia of fibroids, but it is associated with greater risk of intrauterine necrosis. Both methods have low rate of serious complications (except for a high abortion rate).

    Aims The aim was to study the efficacy of gastric lavage and activated charcoal in preventing the absorption of temazepam, verapamil and moclobemide when gastric decontamination was performed immediately after ingestion of the drugs. Methods Nine healthy volunteers took part in a randomized cross-over study with three phases. The subjects were administered single oral doses of 10 mg temazepam, 80 mg verapamil and 150 mg moclobemide. Five minutes later, they were assigned to one of the following treatments: 200 ml water (control), 25 g activated charcoal as a suspension in 200 ml water or gastric lavage. Plasma concentrations and the cumulative excretion into urine of the three drugs were determined up to 24 h. Results The mean AUC(0,24 h) of temazepam, verapamil and moclobemide was reduced by 95.2% (P < 0.01), 92.8% (P < 0.01) and 99.7% (P < 0.01), respectively, by activated charcoal compared with control. Gastric lavage did not reduce significantly the AUC(0,24 h) of these drugs. The 24 h cumulative excretion of temazepam, verapamil and moclobemide into urine was reduced significantly (P < 0.05) by charcoal but not by gastric lavage. Charcoal reduced the AUC(0,24 h), Cmax and urinary excretion of all three drugs significantly more than lavage. Conclusions Activated charcoal is very effective and gastric lavage can be rather ineffective in preventing the absorption of temazepam, verapamil and moclobemide when the treatment is given very rapidly after ingestion of the drugs, before tablet disintegration has occurred.

    Abstract The aim of this article is to analyze factors affecting sonication dose and build a dosimetry model of high-intensity focused ultrasound (HIFU) ablation for uterine fibroids. Four hundred and three patients with symptomatic uterine fibroids who underwent HIFU were retrospectively analyzed. The energy efficiency factor (EEF) was set as dependent variable, and the factors possibly affecting sonication dose included age, body mass index, size of uterine fibroid, abdominal wall thickness, the distance from uterine fibroid dorsal side to sacrum, the distance from uterine fibroid ventral side to skin, location of uterus, location of uterine fibroids, type of uterine fibroids, abdominal wall scar, signal intensity on T2-weighted imaging (T2WI), and enhancement type on T1-weighted imaging (T1WI) were set as predictors to build a multiple regression model. The size of uterine fibroid, distance from fibroid ventral side to skin, location of uterus, location of uterine fibroids, type of uterine fibroids, signal intensity on T2WI, and enhancement type on T1WI had a linear correlation with EEF. The distance from fibroid ventral side to skin, enhancement type on T1WI, size of uterine fibroid, and signal intensity on T2WI were eventually incorporated into the dosimetry model. The distance from fibroid ventral side to skin, enhancement type on T1WI, size of uterine fibroid, and signal intensity on T2WI can be used as dosimetric predictors for HIFU for uterine fibroids.

    Aim: The aim was to study the bronchoalveolar lavage (BAL) technique in evaluating the local immune response of pig immunized with Pasteurella multocida bacterin vaccine. Materials and Methods: Weaned piglets were immunized with formalin-inactivated P52 strain of P. multocida bacterin and evaluated for pulmonary immune response in BAL fluid. BAL was performed before vaccination and at different post vaccination days. The BAL fluid was assayed using enzyme-linked immunosorbent assay to study the development of P. multocida specific antibody isotypes and also evaluated for different cell populations using standard protocol. Results: The average recovery percentage of BAL fluid varies from 58.33 to 61.33 in vaccinated and control group of piglets. The BAL fluid of vaccinated pigs showed increase in antibody titer up to 60th days post vaccination (8.98±0.33), IgG being the predominant isotype reached maximum titer of 6.12±0.20 on 45th days post vaccination, followed by IgM and a meager concentration of IgA could be detected. An increased concentration of the lymphocyte population and induction of plasma cells was detected in the BAL fluid of vaccinated pigs. Conclusion: Though intranasal vaccination with P. multocida plain bacterin vaccine could not provoke a strong immune response, but is promising as lymphocyte population was increased and plasma cells were detected. BAL can be performed repeatedly up to 3/4 months of age in pigs to study pulmonary immune response without affecting their health. PMID:27047111

    Mortality due to leukemia among 4483 women treated with radiation to control uterine bleeding between 1925 and 1965 was twice as high as expected based on U.S. population rates (standardized mortality ratio (SMR) = 2.0; 95% confidence interval (CI): 1.4 to 2.8). Women were followed for an average of 26.4 years. Relative risk was highest 2 to 5 years after treatment (SMR = 8.1) and among women over 55 years at irradiation (SMR = 5.8). The usual method of treatment was intrauterine radium. Average radiation dose to active bone marrow was estimated on the basis of original radiotherapy records (median, 53 cGy). A linear dose-response model provided an adequate fit to the data. The average excess relative risk was 1.9% per cGy (95% CI: 0.8 to 3.2), and the average absolute risk was 2.6 excess leukemia deaths per million women per year per cGy (95% CI: 0.9 to 4.8). Chronic myeloid leukemia predominated during the first 15 years following exposure, whereas acute leukemias and chronic lymphatic leukemia were most common thereafter. The radiation doses experienced during treatment of benign gynecologic disease appear to result in greater leukemia risk per cGy average marrow dose than the considerably higher doses used to treat malignant disease, perhaps because of a decreased likelihood of killing potentially leukemic cells.

  16. Uterine stem cells: what is the evidence?

    PubMed

    2007-01-01

    The mucosal lining (endometrium) of the human uterus undergoes cyclical processes of regeneration, differentiation and shedding as part of the menstrual cycle. Endometrial regeneration also follows parturition, almost complete resection and in post-menopausal women taking estrogen replacement therapy. In non-menstruating species, there are cycles of endometrial growth and apoptosis rather than physical shedding. The concept that endometrial stem/progenitor cells are responsible for the remarkable regenerative capacity of endometrium was proposed many years ago. However, attempts to isolate, characterize and locate endometrial stem cells have only been undertaken in the last few years as experimental approaches to identify adult stem/progenitor cells in other tissues have been developed. Adult stem cells are defined by their functional properties rather than by marker expression. Evidence for the existence of adult stem/progenitor cells in human and mouse endometrium is now emerging because functional stem cell assays are being applied to uterine cells and tissues. These fundamental studies on endometrial stem/progenitor cells will provide new insights into the pathophysiology of various gynaecological disorders associated with abnormal endometrial proliferation, including endometrial cancer, endometrial hyperplasia, endometriosis and adenomyosis.

    Background: Postpartum hemorrhage is the leading cause of severe maternal morbidity and death. A prompt management of uterine artery embolization (UAE) is important for a good outcome. UAE is generally accepted to be a safe and reliable procedure. Objective: To estimate critical patient characteristics influencing the success of UAE for the treatment of emergent primary postpartum hemorrhage. Materials and Methods: This was a cross sectional study that reviewed 121 patients who were diagnosed primary postpartum hemorrhage between February 2002 and December 2009 at a tertiary treatment center among 4,022 deliveries. We evaluated patient clinical characteristics associated with a successful surgical outcome of UAE. Results: The success rate for UAE was 96%. For two cases, UAE complication was associated with fever (>38.5oC). Five patients had problems that required admission to the intensive care unit (ICU). Conclusion: To increase the surgical success rate and lower the number of ICU admissions, the decision to treat primary postpartum hemorrhage using UAE should be based on individual patient clinical findings under the direction of obstetrics staff and an interventional radiologist.

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

    Complaints related to uterine myomatosis treatments received by the National Commission of Medical Arbitration (Conamed) between 2001 and 2005 were analyzed. Complaints were from patients affiliated to social security institutions (51.7 %), private providers (34.5 %) and public health care services (13.8 %). A medical doctor suggested to fill in the complaint in 10.3 % of cases. Perception of inadequate treatment was the most frequent cause (69 %), incomplete medical charts were 60.3 % and only 24 % included the informed consent form. Medical information given to patients and relatives was inadequate (48.2 %). Hysterectomy was performed to 84.5 % of patients. The most frequent surgical complications were hemorrhage (25.7 %), urologic injuries (25.7 %) and surgical infections (12.7 %). 36.4 % of cases had no surgical complication. Main sequelae were: elapsed length of hospital stay (15 %) and loss of an organ (other than uterus) or function (not reproductive) (13.8 %). There was one death (1.7 %). Medical malpractice was found in 29.3 % of cases. Principal deviations: communication problems (29.6 %), unjustified delayed surgery (29.4 %) and delayed diagnosis of complications due to poor post-surgical care or premature hospital discharge (29.4 %).

    Uterine adenoma and uterine bleeding are the two most prevalent diseases in Chinese women. Many women lose their fertility from these diseases. Currently, a minimally invasive ablation system using an RF button electrode is being used in Chinese hospitals to destroy tumor cells or stop bleeding. In this paper, we report on a 3D US guidance system developed to avoid accidents or death of the patient by inaccurate localization of the tumor position during treatment. A 3D US imaging system using a rotational scanning approach of an abdominal probe was built. In order to reduce the distortion produced when the rotational axis is not collinear with the central beam of the probe, a new 3D reconstruction algorithm is used. Then, a fast 3D needle segmentation algorithm is used to find the electrode. Finally, the tip of electrode is determined along the segmented 3D needle and the whole electrode is displayed. Experiments with a water phantom demonstrated the feasibility of our approach.

    The aim of the present study was to investigate the association between serum vascular endothelial growth factor (VEGF) and insulin-like growth factor 1 (IGF-1) levels and the prognosis of patients with uterine fibroids following uterine artery embolization (UAE) treatment. A total of 70 patients with uterine fibroids and 20 healthy controls were enrolled in this study between 2012 and 2014. The serum levels of IGF-1 and VEGF were measured using ELISA. Multiple-factor analysis was performed to assess the association between serum levels of IGF-1/VEGF and certain clinical characteristics, including size, location, number of uterine fibroids and adenomyosis. Progression-free survival curves were analyzed using the Kaplan-Meier method. The serum levels of IGF-1 and VEGF in patients with uterine fibroids prior to UAE treatment were significantly higher than those in controls (P<0.05). At 1 week after UAE treatment, the serum levels of IGF-1 and VEGF were significantly lower compared with those prior to UAE treatment. The serum levels of IGF-1 and VEGF at 1 or 3 months after UAE treatment were significantly higher than those at 1 week after UAE treatment. The serum levels of IGF-1 and VEGF were significantly correlated with the clinical characteristics of uterine fibroids (P<0.05). Lower levels of IGF-1 and VEGF in the serum following UAE treatment were associated with an enhanced progression-free survival of patients. In conclusion, the levels of IGF-1 and VEGF in the serum following UAE treatment can be used as indicators of prognosis in patients with uterine fibroids. PMID:26893660

    BACKGROUND Progesterone is a key hormonal regulator of the female reproductive system. It plays a major role to prepare the uterus for implantation and in the establishment and maintenance of pregnancy. Actions of progesterone on the uterine tissues (endometrium, myometrium and cervix) are mediated by the combined effects of two progesterone receptor (PR) isoforms, designated PR-A and PR-B. Both receptors function primarily as ligand-activated transcription factors. Progesterone action on the uterine tissues is qualitatively and quantitatively determined by the relative levels and transcriptional activities of PR-A and PR-B. The transcriptional activity of the PR isoforms is affected by specific transcriptional coregulators and by PR post-translational modifications that affect gene promoter targeting. In this context, appropriate temporal and cell-specific expression and function of PR-A and PR-B are critical for normal uterine function. METHODS Relevant studies describing the role of PRs in uterine physiology and pathology (endometriosis, uterine leiomyoma, endometrial cancer, cervical cancer and recurrent pregnancy loss) were comprehensively searched using PubMed, Cochrane Library, Web of Science, and Google Scholar and critically reviewed. RESULTS Progesterone, acting through PR-A and PR-B, regulates the development and function of the endometrium and induces changes in cells essential for implantation and the establishment and maintenance of pregnancy. During pregnancy, progesterone via the PRs promotes myometrial relaxation and cervical closure. Withdrawal of PR-mediated progesterone signaling triggers menstruation and parturition. PR-mediated progesterone signaling is anti-mitogenic in endometrial epithelial cells, and as such, mitigates the tropic effects of estrogen on eutopic normal endometrium, and on ectopic implants in endometriosis. Similarly, ligand-activated PRs function as tumor suppressors in endometrial cancer cells through inhibition of key

    Innate lymphoid cells (ILCs), including NK cells, contribute to barrier immunity and tissue homeostasis. In addition to the role of uterine NK cells in placentation and fetal growth, other uterine ILCs (uILCs) are likely to play roles in uterine physiology and pathology. In this article, we report on the composition of uILCs in the endometrium during the luteal phase and in the decidua during early pregnancy. Whereas nonkiller uILC1s and uILC2s are barely detectable in mouse and not detected in humans, a sizeable population of uILC3s is found in human endometrium and decidua, which are mostly NCR+ and partially overlap with previously described IL-22–producing uterine NK cells. Development of mouse uILC3 is Nfil3 independent, suggesting unique features of uILCs. Indeed, although the cytokine production profile of mouse uILCs recapitulates that described in other tissues, IL-5, IL-17, and IL-22 are constitutively produced by uILC2s and uILC3s. This study lays the foundation to understand how ILCs function in the specialized uterine mucosa, both in tissue homeostasis and barrier immunity and during pregnancy. PMID:26371244

  4. Diagnostic and prognostic markers for uterine diseases in dogs.

    PubMed

    2014-06-01

    Common uterine diseases in female dogs include cystic endometrial hyperplasia (CEH), mucometra, hydrometra and pyometra. It is important in clinical practice to recognize pyometra because it is potentially life-threatening due to the systemic illness induced by bacterial infection of the uterus. In contrast, the uterine content is sterile in CEH and mucometra/hydrometra, and clinical signs are mostly mild or absent. Optimal treatment depends on the type of uterine disease and its severity, but diagnosis and prognosis determination may be challenging and the diseases difficult to separate clinically. Diagnostic findings or biomarkers that may aid in the differentiation of the diseases are valuable, especially when several bitches are admitted with a fluid-filled uterus during night-time, and it has to be decided which patient to operate on first. Additionally, some variables may indicate outcome as measured by mortality or morbidity. If the uterus is not enlarged or fluid-filled, detection of uterine disease can be even more difficult. In this study, clinically useful variables with possible diagnostic or prognostic value for uterine diseases in dogs are discussed. PMID:24947856

    The aim of this study was to investigate gray scale and color flow characteristics of a group of patients with a suspected uterine pathologic condition. One hundred and twenty-two consecutive patients at the Women's Cancer Center, University of Minnesota, undergoing transvaginal sonography and color flow Doppler imaging for suspected uterine corpus abnormality made up the study group. After gray scale morphologic assessment, color flow Doppler imaging of the tumor and uterus was performed, including the ipsilateral uterine artery. Malignant tumors were confirmed pathologically in all 35 patients who had them. In comparing patients with benign versus malignant tumors, gray scale morphologic assessment confirmed that malignant uterine tumors (31 endometrial cancers and four sarcomas) were more likely to have a thickened echoic endometrium (P = < 0.0001), be enlarged (P = 0.004), to be retroverted (P = 0.02), and to lack a subendometrial halo (P < 0.0001). Patients with four benign and 13 malignant tumors demonstrated increased flow when assessed by CFD. The calculated sensitivity of increased color flow in predicting malignancy was 39%, with a specificity of 92%, a positive predictive value of 77%, and a negative predictive value of 71%. No difference existed between the benign and malignant groups for the systolic, diastolic, and mean velocities and for the calculated pulsatility index and resistive index in both sampled uterine and intramyometrial or tumor vessels.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7837328

    Uterine torsion is defined as a rotation on its long axis and it is a dangerous, unexpected obstetric emergency. We report a case of uterine torsion at 32 weeks of gestation in a singleton pregnancy. A 37-year-old woman with multiple prior cesarean deliveries referred to emergency unit of our hospital at 32 weeks of gestation with severe abdominal pain and mild vaginal bleeding. Ultrasonography showed a single fetus in vertex position, with a normal amniotic fluid. Fetal biometer was appropriate for 32 weeks of gestation. Placental location was anterior with a subchorionic hypoechogenic small area which was suspected to be a sign of placental abruption. An emergency cesarean section was performed under general anesthesia. The 180° uterine torsion was diagnosed and it was not possible to perform detorsion of the gravid uterus by exteriorization by pfannenstiel incision. Posterior hysterotomy was performed and a male baby of 1830 grams weight was delivered. The newborn was transported to Neonatal Intensive Care Unit (NICU) of another hospital and discharged within two weeks. Patient recovered well and was discharged on second postoperation day. Uterine torsion is a very rare and life threatening situation. In unexpected cases posterior low transuerse hysterotomy is generally performed and it is suggested as a safe choice when detorsion was not accomplished. It is not easy to keep in mind the possibility of uterine torsion in cases of abdominal pain during pregnancy. Because it generally causes abruption, management of abruption is vitally important to prevent fetal mortality. PMID:26894131

    Quantitative measurements of the effects of irradiation on normal tissues in humans have been hard to obtain because most tissues are inaccessible and/or direct responses are difficult to quantify in a nondestructive manner. Pneumonitis and fibrotic lung disease are adverse effects seen in varying intensity in patients treated with radiotherapy for carcinomas of the thorax, e.g., breast cancer. In the present study the aim was to evaluate the inflammatory reaction in the underlying parenchyma following postoperative irradiation with bronchoalveolar lavage technique. Twenty-one patients with breast cancer stage T1N0M0 received radiotherapy with photons to a target dose of 56 Gy following breast conservative surgery. Nineteen healthy controls were also included. The results showed a clear elevation of neutrophils, mast cells, eosinophils, and lymphocytes in the total irradiated groups, compared to controls. When subclassifying the material according to smoking habit, it was obvious that the smokers displayed a significantly decreased inflammatory reaction, i.e., reduced levels of mast cells and lymphocytes, compared to both nonsmoking controls and patients. Eosinophils were seen in an elevated number in all irradiated patients. Radiological signs of pneumonitis were observed in three patients, all in the nonsmoking group. No correlation was found between the volume of lung irradiated and the inflammatory response. It is concluded that bronchoalveolar lavage is a suitable and sensitive method for investigating radiotherapy-induced reactions in the human lung. Furthermore, ongoing smoking during the treatment depressed the inflammatory response in the lung parenchyma induced by irradiation. The present study as well as earlier observations justify further studies concerning the possibility of interaction of smoking with cancer treatment.

    A 51-year-old man with chief complaints of cough, fever, and dyspnea was admitted to our hospital. Based on a home provocation test, transbronchial lung biopsy specimens, and a serum antibody, we diagnosed summer-type hypersensitivity pneumonitis. In 1983 when the patient was 46 years old, thymectomy was performed for thymoma. Prior to surgery, bronchoalveolar lavage (BAL) was performed. Total cell count and neutrophils had already increased in BALF. Furthermore, the increase in BALF cell neutrophil count was also seen at the time of admission and after the home provocation test. Because an increase of neutrophils in BALF cells was seen not only at onset but before onset, further studies are required to clarify the role of neutrophils and the factors that increase them in hypersensitivity pneumonitis.

    An important problem in realizing personalized medicine is the development of methods for identifying disease subtypes using quantitative proteomics. Recently we found that bronchoalveolar lavage (BAL) cytokine patterns contain information about dynamic lung responsiveness. In this study, we examined physiological data from 1048 subjects enrolled in the US Severe Asthma Research Program (SARP) to identify four largely separable, quantitative intermediate phenotypes. Upper extremes in the study population were identified for eosinophil- or neutrophil- predominant inflammation, bronchodilation in response to albuterol treatment, or methacholine sensitivity. We evaluated four different statistical (“machine”) learning methods to predict each intermediate phenotypes using BAL cytokine measurements on a 76 subject subset. Comparison of these models using area under the ROC curve and overall classification accuracy indicated that logistic regression and multivariate adaptive regression splines produced the most accurate methods to predict intermediate asthma phenotypes. These robust classification methods will aid future translational studies in asthma targeted at specific intermediate phenotypes. PMID:20718815

    Background Although surgeons acknowledge the importance of irrigating open fracture wounds, the choice of irrigating fluid and delivery pressure remains controversial. Our objective was to clarify current opinion with regard to the irrigation of open fracture wounds. Methods We used a cross-sectional survey and a sample-to-redundancy strategy to examine surgeons' preferences in the initial management of open fracture wounds. We mailed this survey to members of the Canadian Orthopaedic Association and delivered it to attendees of an international fracture course (AO, Davos, Switzerland). Results Of the 1,764 surgeons who received the questionnaire, 984 (55.8%) responded. In the management of open wounds, the majority of surgeons surveyed, 676 (70.5%), favoured normal saline alone. Bacitracin solution was used routinely by only 161 surgeons (16.8%). The majority of surgeons, 695 (71%) used low pressures when delivering the irrigating solution to the wound. There was, however considerable variation in what pressures constituted high versus low pressure lavage. The overwhelming majority of surgeons, 889 (94.2%), reported they would change their practice if a large randomized controlled trial showed a clear benefit of an irrigating solution – especially if it was different from the solution they used. Conclusion The majority of surgeons favour both normal saline and low pressure lavage for the initial management of open fracture wounds. However, opinions varied as regards the comparative efficacy of different solutions, the use of additives and high versus low pressure. Surgeons have expressed considerable support for a trial evaluating both irrigating solutions and pressures. PMID:18215287

    This study was undertaken to determine the relationship of soluble intercellular adhesion molecule 1 (sICAM-1) levels in bronchoalveolar lavage (BAL) fluid during allergic airway inflammation to those in the vascular compartment and to cellular components in the BAL fluids. A group of 11 allergic subjects underwent initial bronchoscopy during which a control BAL was performed and normal saline (NS) and specific antigen (Ag) were administered to two sublobar segments. A second bronchoscopy was performed 17 to 21 h later, and the NS and Ag segments were lavaged. Blood was drawn before each bronchoscopic procedure. The mean concentration of sICAM-1 in BAL fluid from NS-challenged segments was 59.2 +/- 7.6 ng/ml and was not different from that in unchallenged segments (51.5 +/- 5.6 ng/ml). In BAL fluid from Ag-challenged segments, mean concentrations of sICAM-1 increased significantly to 97.5 +/- 12.5 ng/ml. Segmental antigen challenge was associated with a small but statistically significant increase in sICAM-1 concentrations in serum. The concentrations of sICAM-1 in BAL fluid after antigen challenge exceeded levels that could be accounted for by passive transudation from the circulation, based upon the magnitude of increases in BAL albumin concentrations. The levels of sICAM-1 in BAL from Ag-challenged segments were correlated significantly with the total white cell, lymphocyte, neutrophil, and eosinophil counts in BAL fluids. These results are supportive of the notion that the local release of sICAM-1 may play a role in allergen-induced inflammatory processes in the airways. PMID:7916246

    In Finland, unlike other countries, anthophyllite asbestos has been widely used due to its domestic production in 1918-1975. In this particular context, the aim of the present study was to analyse the relationship between asbestos bodies (ABs) in bronchoalveolar lavage (BAL) fluid and the concentration of ABs and the different amphibole asbestos fibres in lung tissue. Sixty five BAL lung tissue sample pairs from patients with pulmonary disease were analysed. The concentration of ABs in BAL fluid and lung tissue was determined with optical microscopy, and the concentration, type and dimensions of asbestos fibres in lung tissue with scanning electron microscopy. There was a significant correlation between the concentrations of ABs in BAL fluid and in lung tissue (r = 0.72; p < 0.001), between the concentrations of ABs and amphibole asbestos fibres in lung tissue (r = 0.73; p < 0.001), and between the concentration of ABs in BAL fluid and the concentration of amphibole asbestos fibres in lung tissue (r = 0.64; p < 0.001). In patients who had been exposed mainly to commercial anthophyllite, significantly higher concentrations of ABs were observed per total pulmonary amphibole fibre burden, as compared to patients whose main exposure was to crocidolite/amosite. The anthophyllite fibres in lung tissue were longer than the crocidolite/amosite fibres. The relationship between asbestos body counts in lung tissue and in bronchoalveolar lavage fluid was similar to previous international observations. When using the asbestos body count to predict the underlying total pulmonary amphibole asbestos burden in Finnish patients, however, it should be borne in mind that the relationship between the two parameters seems to be different with anthophyllite as compared to crocidolite/amosite fibres.

    Today around 275000 women a year in the world keep dying from the cancer of uterine cervix due to the difficulty to meet the logistic requirements of an organized screening in the developing world. Polarimetric imaging is a new promising technique with a tremendous potential for applications in biomedical diagnostics: it is sensitive to slight morphological changes in tissues, can provide wide field images for the screening and requires light sources such as a LED for example. This work intends to characterize the polarimetric response of the uterine cervix in its healthy and pathological states. An extensive series of ex-vivo measurements is in progress the Kremlin Bicêtre hospital near Paris using an imaging multispectral Mueller polarimeter in backscattering configuration. The goal of this study is to evaluate the performances of polarimetric imaging technique in terms of sensitivity and specificity for the detection of healthy epithelia (Healthy Squamous epithelium and Malpighian Metaplasia) with respect to the diagnosis provided by pathologists from histology slides as the "gold standard". We show that, at λ=550nm, performances as high as 62% sensitivity and 64% specificity are achieved by optimizing a simple threshold on the scalar retardance values.

    Dose-response studies were conducted with Syrian hamsters exposed to polyethylene glycol p-isooctylphenyl ether (Triton X-100) via inhalation or bronchopulmonary lavage. Syrian hamsters were exposed to an aerosol of Triton X-100 with a mass median aerodynamic diameter of 1.5 ..mu..m and a concentration of 3.0 mg/liter. Estimated initial lung burdens of Triton X-100 ranged from 800 to 3100 ..mu..g. Hamsters were lavaged with concentrations of Triton X-100 ranging from 0.01 to 0.10% in isotonic saline resulting in initial lung burdens of Triton X-100 that ranged from 300 to 3200 ..mu..g. The LD50/7 values were 1700 ..mu..g (1300 to 2100 ..mu..g, 95% confidence limits) for the inhalation study and 2100 (1900 to 2700) ..mu..g for the lavage study. The difference between the LD50/7 values for the two methods of exposure was not significant. However, histopathological examination revealed differences in the nature and distribution of pathologic changes observed in animals exposed by the two routes of administration. Animals exposed by inhalation died as a result of ulcerative laryngitis and laryngeal edema with only minimal pulmonary pathologic alterations. Animals exposed by lavage, where the larynx was not exposed to Triton X-100, died from pulmonary edema and acute exudative pneumonia. These results demonstrate the need for careful selection of exposure methods to meet the specific objectives of a toxicology study.

    ABSTRACT Objectives The purpose of this study was to examine magnetic resonance imaging findings in patients with painful disc displacement without reduction of the temporomandibular joint to determine whether the findings were able to predict treatment outcome of lavage and a control group treated with local anaesthesia without lavage in a short-term: 3-month perspective. Material and Methods Bilateral magnetic resonance images were taken of 37 patients with the clinical diagnosis of painful disc displacement without reduction. Twenty-three patients received unilateral extra-articular local anaesthetics and 14 unilateral lavage and extra-articular local anaesthetics. The primary treatment outcome defining success was reduction in pain intensity of at least 30% during jaw movement at the 3-month follow-up. Results Bilateral disc displacement was found in 30 patients. In 31 patients the disc on the treated side was deformed, and bilaterally in 19 patients. Osteoarthritis was observed in 28 patients, and 13 patients had bilateral changes. Thirty patients responded to treatment and 7 did not, with no difference between the two treated groups. In neither the treated nor the contralateral temporomandibular joint did treatment outcome depend on disc diagnosis, disc shape, joint effusion, or osseous diagnoses. Magnetic resonance imaging findings of disc position, disc shape, joint effusion or osseous diagnosis on the treated or contralateral side did not give information of treatment outcome. Conclusions Magnetic resonance imaging findings could not predict treatment outcome in patients treated with either local anaesthetics or local anaesthetics and lavage. PMID:25937876

    Metal oxide particles with diameters of less than 0.1 micron (ultrafine particles) are important products of fossil fuel combustion. Pulmonary lavage fluid was obtained from guinea pigs given 1, 2, or 3 consecutive, daily, 3-h, nose-only exposures to 0, 2.3, 5.9, or 12.1 mg/m3 of freshly generated zinc oxide (ZnO) particles with a projected area diameter of 0.05 micron. Exposure to ZnO at 5.9 or 12.1 mg/m3 was associated with increased protein, neutrophils, and activities of angiotensin-converting enzyme, alkaline phosphatase, acid phosphatase and lactate dehydrogenase in lavage fluid, and with histologic evidence of pulmonary damage characterized by centriacinar inflammation. The severity of inflammation, graded by the number of inflammatory foci per square centimeter of lung, correlated with the amount of protein and the activity of angiotensin-converting enzyme and other enzymes in lavage fluid. These results indicate that analysis of pulmonary lavage fluid is a useful and sensitive method for quantitative evaluation of pulmonary damage caused by inhalation of low levels of ultrafine ZnO.

    Uterine incarceration is a rare complication that usually occurs after the first trimester of pregnancy. It leads to increased maternal and/or fetal morbidity and mortality. Risk factors include retroversion of uterus and other pelvic abnormalities. Clinical presentation includes severe abdominal and pelvic pain symptoms. Patients can present with concurrent urinary symptoms due to increasing distortion of adjacent structures from the enlarging uterus. A high clinical suspicion of uterine incarceration is confirmed with ultrasound. More advanced imaging such as MRI can be used as an adjunct to ultrasound imaging. Progression from expectant management to intervention is recommended as soon as possible to prevent complications such as uterine rupture and fetal demise. In subsequent pregnancies, close monitoring with serial ultrasounds is warranted to monitor for recurrence of incarceration which has been reported in a few rare cases. PMID:27402652

    Approximately 30% of women will experience abnormal uterine bleeding (AUB) during their life time. Previous terms defining AUB have been confusing and imprecisely applied. As a consequence, both clinical management and research on this common problem have been negatively impacted. In 2011, the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG) published PALM-COEIN, a new classification system for abnormal bleeding in the reproductive years. Terms such as menorrhagia, menometrorrhagia, metrorrhagia, dysfunctional uterine bleeding, polymenorrhea, oligomenorrhea, and uterine hemorrhage are no longer recommended. The PALM-COEIN system was developed to standardize nomenclature to describe the etiology and severity of AUB. A brief description of the PALM-COEIN nomenclature is presented as well as treatment options for each etiology. Clinicians will frequently encounter women with AUB and should report findings utilizing the PALM-COEIN system. PMID:26969858

    The distribution of DNA ploidy levels and its prognostic significance in cervical cancer (including squamous cell carcinoma and adenocarcinoma) and endometrial cancer is discussed. DNA aneuploidy was observed in most of the cases with either the histological type of cervical cancer and in half of those with endometrial cancer. The DNA ploidy level of the tumor showed a characteristic distribution according to its histological type or grade. Although several investigators have already reported that patients with DNA diploid uterine tumors had a better survival than those with DNA aneuploid uterine tumors, further research is required before a definite conclusion can be attained on the prognostic value of the degree of DNA ploidy measurement in uterine cancer.

    We present a rare case with gossypiboma following cesarean section which led to uterine wound dehiscence. A 30-year-old woman had been submitted to an emergency cesarean section 4 months previously at another hospital. Clinical and ultrasound findings revealed a large intra-abdominal mass and diffuse peritonitis. At laparotomy, a gossypiboma causing an abscess and uterine wound dehiscence with necrosis of the margins was detected. We performed repetitive wound debridements under broad-spectrum antibiotic cover and eventually resutured the incision. Although hysterectomy has so far been the choice of treatment in the literature once a uterine wound dehiscence had occurred, it was possible in this case to preserve the uterus. PMID:24106624

    Background: We have identified candidate protein and microRNA (miRNA) biomarkers for dyspnea by studying serum, lavage fluid, and urine from military personnel who reported serious respiratory symptoms after they were deployed to Iraq or Afghanistan. Methods: Forty-seven soldiers with the complaint of dyspnea who enrolled in the STudy of Active Duty Military Personnel for Environmental Dust Exposure (STAMPEDE) underwent comprehensive pulmonary evaluations at the San Antonio Military Medical Center. The evaluation included fiber-optic bronchoscopy with bronchoalveolar lavage. The clinical findings from the STAMPEDE subjects pointed to seven general underlying diagnoses or findings including airway hyperreactivity, asthma, low diffusivity of carbonmore » monoxide, and abnormal cell counts. The largest category was undiagnosed. As an exploratory study, not a classification study, we profiled proteins or miRNAs in lavage fluid, serum, or urine in this group to look for any underlying molecular patterns that might lead to biomarkers. Proteins in lavage fluid and urine were identified by accurate mass tag (database-driven) proteomics methods while miRNAs were profiled by a hybridization assay applied to serum, urine, and lavage fluid. Results: Over seventy differentially expressed proteins were reliably identified both from lavage and from urine in forty-eight dyspnea subjects compared to fifteen controls with no known lung disorder. Six of these proteins were detected both in urine and lavage. One group of subjects was distinguished from controls by expressing a characteristic group of proteins. A related group of dyspnea subjects expressed a unique group of miRNAs that included one miRNA that was differentially overexpressed in all three fluids studied.

    Uterine stromal cell decidualization is an essential part of the reproductive process. Decidual tissue development requires a highly regulated control of the extracellular tissue remodeling; however the mechanism of this regulation remains unknown. Through systematic expression studies, we detected that Cbx4/2, Rybp, and Ring1B [components of polycomb repressive complex 1 (PRC1)] are predominantly utilized in antimesometrial decidualization with polyploidy. Immunofluorescence analyses revealed that PRC1 members are co-localized with its functional histone modifier H2AK119ub1 (mono ubiquitination of histone-H2A at lysine-119) in polyploid cell. A potent small-molecule inhibitor of Ring1A/B E3-ubiquitin ligase or siRNA-mediated suppression of Cbx4 caused inhibition of H2AK119ub1, in conjunction with perturbation of decidualization and polyploidy development, suggesting a role for Cbx4/Ring1B-containing PRC1 in these processes. Analyses of genetic signatures by RNA-seq studies showed that the inhibition of PRC1 function affects 238 genes (154 up and 84 down) during decidualization. Functional enrichment analyses identified that about 38% genes primarily involved in extracellular processes are specifically targeted by PRC1. Furthermore, ~15% of upregulated genes exhibited a significant overlap with the upregulated Bmp2 null-induced genes in mice. Overall, Cbx4/Ring1B-containing PRC1 controls decidualization via regulation of extracellular gene remodeling functions and sheds new insights into underlying molecular mechanism(s) through transcriptional repression regulation.

    Objective Uterine leiomyomata (UL) are a major source of gynecologic morbidity and the primary indication for hysterectomy. Depression can cause dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, which may affect the synthesis of reproductive hormones involved in UL pathogenesis. We assessed the association between depressive symptoms and UL among 15,963 premenopausal women. Study Design Data were derived from the Black Women’s Health Study, a prospective cohort study. In 1999 and 2005, the Center for Epidemiologic Studies Depression Scale (CES-D) was used to ascertain depressive symptoms. On biennial follow-up questionnaires from 1999 through 2011, women reported physician-diagnosed depression, antidepressant use, and UL diagnoses. Incidence rate ratios (IRR) and 95% confidence intervals (CI) were estimated using multivariable Cox regression. Results There were 4,722 incident UL cases diagnosed by ultrasound (n=3,793) or surgery (n=929) during 131,262 person-years of follow-up. Relative to baseline CES-D scores <16, IRRs were 1.05 (95% CI, 0.98–1.13) for CES-D scores 16–24 and 1.16 (95% CI, 1.06–1.27) for CES-D scores ≥25 (P-trend=0.001). IRRs for current and past physician-diagnosed depression relative to no depression were 1.15 (95% CI: 0.98, 1.34) and 1.25 (95% CI: 1.13, 1.39), respectively. Results persisted after further control for antidepressant use. IRRs for current and past use of antidepressants (any indication) relative to never use were 1.11 (95% CI: 0.97, 1.28) and 1.32 (95% CI: 1.14, 1.52), respectively. Conclusions In this cohort of black women, greater depressive symptoms were associated with UL, independent of antidepressant use, supporting the hypothesis that dysregulation of the HPA axis increases UL risk.

    Abnormal Uterine Bleeding (AUB) is one of the most common health problems encountered by women. It affects about 20% women of reproductive age, and accounts for almost two thirds of all hysterectomies. Gynaecologists are often unable to identify the cause of abnormal bleeding even after a thorough history and physical examination. Diagnostic evaluations and treatment modalities have been evolving over time. The onus in AUB management is to exclude complex endometrial hyperplasia and endometrial cancer. From D and C + EUA under general anesthesia the shift to more accurate procedures like hysteroscopy and vision directed biopsy was welcome. But the current minimally invasive procedures like sonohysterography, office vacuum aspiration (Pipelle) and the use of office hysteroscopy have revolutionized the management of AUB. We have tried to review the current literature and guidelines for evaluation of endometrium with the twin goals of finding an accurate reason causing the AUB and to rule out endometrial cancer or a potential for the cancer in future. We have also attempted to compare the current procedures and their present perspective vis-à-vis each other. Histological assessment is the final word, but obtaining a sample for histology makes it more accurate, and we have reviewed these techniques to enhance accuracy in diagnosis. Hysteroscopy and directed biopsy is the ‘gold standard’ approach for most accurate evaluation of endometrium to rule out focal endometrial Ca. Blind endometrial biopsies should no longer be performed as the sole diagnostic strategy in perimenopausal as well as in postmenopausal women with AUB. A single-stop approach, especially in high risk women (Obesity, diabetes, family history of endometrial, ovarian or breast cancer) as well as in women with endometrial hyperplasia of combining the office hysteroscopy, directed biopsy in presence of a focal lesion, and vacuum sampling of endometrium in normal looking endometrium, all without

    Development of uterine glands (adenogenesis) in mammals typically begins during the early post-natal period and involves budding of nascent glands from the luminal epithelium and extensive cell proliferation in these structures as they grow into the surrounding stroma, elongate and mature. Uterine glands are essential for pregnancy, as demonstrated by the infertility that results from inhibiting the development of these glands through gene mutation or epigenetic strategies. Several genes, including forkhead box A2, beta-catenin and members of the Wnt and Hox gene families, are implicated in uterine gland development. Progestins inhibit uterine epithelial proliferation, and this has been employed as a strategy to develop a model in which progestin treatment of ewes for 8 weeks from birth produces infertile adults lacking uterine glands. More recently, mouse models have been developed in which neonatal progestin treatment was used to permanently inhibit adenogenesis and adult fertility. These studies revealed a narrow and well-defined window in which progestin treatments induced permanent infertility by impairing neonatal gland development and establishing endometrial changes that result in implantation defects. These model systems are being utilized to better understand the molecular mechanisms underlying uterine adenogenesis and endometrial function. The ability of neonatal progestin treatment in sheep and mice to produce infertility suggests that an approach of this kind may provide a contraceptive strategy with application in other species. Recent studies have defined the temporal patterns of adenogenesis in uteri of neonatal and juvenile dogs and work is underway to determine whether neonatal progestin or other steroid hormone treatments might be a viable contraceptive approach in this species.

    ABSTRACT Changes in the CD-1 mouse uterine transcriptome during proestrus and estrus were investigated to help elucidate mechanisms of uterine tissue remodeling during the estrus cycle and their regulation by estrogen and progesterone in preparation of the uterus for pregnancy. Mice were staged beginning at 6 weeks of age, and uterine horns were harvested after monitoring two estrus cycles. Microarray analysis of whole uterine horn RNA identified 2428 genes differentially expressed in estrus compared to proestrus, indicating there is extensive remodeling of mouse uterus during the estrus cycle, affecting ∼10% of all protein-encoding genes. Many (∼50%) of these genes showed the same differential expression in independent analyses of isolated uterine lumenal epithelial cells. Changes in gene expression associated with structural alterations of the uterus included remodeling of the extracellular matrix, changes in cell keratins and adhesion molecules, activation of mitosis and changes in major histocompatibility complex class II (MHCII) presentation, complement and coagulation cascades, and cytochrome P450 expression. Signaling pathways regulated during the estrus cycle, involving ligand-gated channels, Wnt and hedgehog signaling, and transcription factors with poorly understood roles in reproductive tissues, included several genes and gene networks that have been implicated in pathological states. Many of the molecular pathways and biological functions represented by the genes differentially expressed from proestrus to estrus are also altered during the human menstrual cycle, although not necessarily at the corresponding phases of the cycle. These findings establish a baseline for further studies in the mouse model to dissect mechanisms involved in uterine tissue response to endocrine disruptors and the development of reproductive tract diseases.

    Development of uterine glands (adenogenesis) in mammals typically begins during the early post-natal period and involves budding of nascent glands from the luminal epithelium and extensive cell proliferation in these structures as they grow into the surrounding stroma, elongate and mature. Uterine glands are essential for pregnancy, as demonstrated by the infertility that results from inhibiting the development of these glands through gene mutation or epigenetic strategies. Several genes, including forkhead box A2, beta-catenin and members of the Wnt and Hox gene families, are implicated in uterine gland development. Progestins inhibit uterine epithelial proliferation, and this has been employed as a strategy to develop a model in which progestin treatment of ewes for 8 weeks from birth produces infertile adults lacking uterine glands. More recently, mouse models have been developed in which neonatal progestin treatment was used to permanently inhibit adenogenesis and adult fertility. These studies revealed a narrow and well-defined window in which progestin treatments induced permanent infertility by impairing neonatal gland development and establishing endometrial changes that result in implantation defects. These model systems are being utilized to better understand the molecular mechanisms underlying uterine adenogenesis and endometrial function. The ability of neonatal progestin treatment in sheep and mice to produce infertility suggests that an approach of this kind may provide a contraceptive strategy with application in other species. Recent studies have defined the temporal patterns of adenogenesis in uteri of neonatal and juvenile dogs and work is underway to determine whether neonatal progestin or other steroid hormone treatments might be a viable contraceptive approach in this species.

    Deep veins (DVs) can be compressed by a uterus enlarged with fibroids. The purpose of this study was to assess the degree of luminal narrowing of DVs caused by a myomatous uterus, and the change in DV narrowing in women with symptomatic fibroids after embolization using time-of-flight (TOF)-magnetic resonance venography (MRV). Twenty-nine consecutive women with symptomatic uterine fibroids underwent TOF-MRV and pelvic MRI before and 4 months after embolization. Based on the TOF-MRV, we evaluated the luminal narrowing of three DVs, including the inferior vena cava, and the bilateral common and external iliac veins, and divided the findings into three grades. The scores for each DV were added for each patient (lowest, 0; highest, 6). DV scores and symptom severity (SS) scores were compared between the baseline and 4 months after embolization using the paired t-test. The relationship between DV scores and uterine volume was investigated using Pearson's test. DV scores decreased significantly, from 1.52 {+-} 1.70 at baseline to 0.93 {+-} 1.56 at 4 months after embolization (p = 0.004). The uterine volume decreased from 948 {+-} 647 mL at baseline to 617 {+-} 417 mL at 4 months after embolization (p < 0.001). DV score correlated with uterine volume (r = 0.856, p < 0.001). SS scores decreased from 54.5 {+-} 14.6 at baseline to 26.8 {+-} 15.4 at 4 months after embolization (p < 0.001). In conclusion, the degree of luminal narrowing of DVs caused by a uterus with fibroids is correlated with the uterine volume. Uterine artery embolization may induce an improvement of luminal narrowing of DVs due to a reduction of the myomatous uterus volume.

    The field of reproductive medicine witnessed a breakthrough in September 2014 with the first successful live birth post uterine transplantation. This success represents the culmination of decades' worth of research on infertility and reproductive medicine. This subject of infertility gathers special attention in the Middle East, as childbearing is given paramount importance in the family unit. And as with any new medical advancement, Middle Eastern people look to their religious authorities for guidance. This paper describes the various ethical quandaries related to uterine transplantation, from a perspective of the religious and societal factors that are unique to the Middle East, and embeds them within the conversation of its alternative solutions.

    Uterine leiomyomas are one of the most common benign smooth muscle tumors in women, with a prevalence of 20 to 40% in women over the age of 35 years. Fifty percent of them may necessitate treatment, because of bleeding, pelvic pain and infertility. Laparoscopic myomectomy is one of the treatment options. The major concern of myomectomy either by open procedure or by laparoscopy is the bleeding encountered during the operation. One of the methods to reduce the intraoperative blood loss and to prevent excessive bleeding is the clipping of both uterine arteries and aa. ovaricae. PMID:26817264

    An unusual uterine adenolipoleiomyoma forming intramural and subserosal masses and recurring within 16 months in the form of huge coalescent uterine masses is described. Histology showed the mass to be composed of benign-appearing smooth muscle, mature adipose tissue, and bland endocervical-type glands. The recurrent adenolipoleiomyoma contained, in addition, benign-appearing endometrial-type glands and stroma and showed small foci of atypically proliferating endocervical-type epithelium. This is the fourth report of adenolipoleiomyoma within the uterus, the second with an intramural location, and the first with an aggressive behavior in the form of massive local recurrence.

    Implantation of the fertilized egg into the maternal uterus is a crucial step in pregnancy establishment. Increasing evidence suggests that its success depends on various cell types of the innate immune system and on the fine balance between inflammatory and anti-inflammatory processes. In addition, it has recently been established that regulatory T cells play a superordinate role in dictating the quality of uterine environment required for successful pregnancy. Here, we discuss the cellular regulation of uterine receptivity with emphasis on the function and regulation of cells from the innate and adaptive immune system. PMID:26136750

    Management of Postpartal Haemorrhage (PPH) refractory to medical management continues to be a formidable condition, further compounded by unstable haemodynamic condition and associated coagulopathy, usually associated with this condition. Though surgical exploration is the usual therapeutic option for such patients, selective pelvic arterial embolisation is gaining the popularity in view of its safety and efficacy profile. Uterine preservation further adds to its advantages. We present our experience of managing 5 such patients with Uterine Artery Embolisation (UAE). The current status of UAE as therapeutic modality for management of refractory PPH is discussed. PMID:23373044

    Purpose To test the hypothesis that four-dimensional (4D) transcatheter intra-arterial perfusion (TRIP) MR imaging can measure uterine fibroid perfusion changes immediately before and after uterine artery embolization (UAE) in the rabbit VX2 tumor model. Materials and Methods Eight VX2 uterine tumors were grown in 6 rabbits. After positioning a catheter within the uterine artery, we performed 4D TRIP-MRI measurements with 3 mL injections of 2.5% gadopentetate dimeglumine. We used a dynamic 3D spoiled-GRE sequence with in vivo B1-field correction for improved accuracy during perfusion quantification. We performed UAE using 1 mL of gelatin microspheres (2×106 particles; diameter 40-120 μm). Two regions-of-interest were drawn within each tumor upon perfusion maps. Functional embolic endpoints were reported as the mean percent reduction in fibroid tumor perfusion. Measurements before and after UAE were compared using paired t-tests (α = 0.05). Results VX2 uterine tumor perfusion decreased significantly from 27.1 at baseline to 7.09 after UAE (mL/min/100 mL tissue, p < 0.0001). Overall perfusion reduction was 76.3% (95% CI: 66.3%-86.3%). Conclusion 4D TRIP MRI can objectively quantify uterine fibroid perfusion reductions during UAE in VX2 rabbits. This technique could be used clinically to potentially determine an optimal embolic endpoint with the long-term goals of improving UAE success rates and minimizing procedure-related ischemic pain.

    Purpose: Brachytherapy (BT) is an important treatment technique for uterine corpus malignancies. We modeled the optimal proportion of these cases that should be treated with BT-the optimal rate of brachytherapy utilization (BTU). We compared this optimal BTU rate with the actual BTU rate. Methods and Materials: Evidence-based guidelines and the primary evidence were used to construct a decision tree for BTU for malignancies of the uterine corpus. Searches of the literature to ascertain the proportion of patients who fulfilled the criteria for BT were conducted. The robustness of the model was tested by sensitivity analyses and peer review. A retrospective Patterns of Care Study of BT in New South Wales for 2003 was conducted, and the actual BTU for uterine corpus malignancies was determined. The actual BTU in other geographic areas was calculated from published reports. The differences between the optimal and actual rates of BTU were assessed. Results: The optimal uterine corpus BTU rate was estimated to be 40% (range, 36-49%). In New South Wales in 2003, the actual BTU rate was only 14% of the 545 patients with uterine corpus cancer. The actual BTU rate in 2001 was 11% in the Surveillance, Epidemiology, and End Results areas and 30% in Sweden. Conclusion: The results of this study have shown that BT for uterine corpus malignancies is underused in New South Wales and in the Surveillance, Epidemiology, and End Results areas. Our model of optimal BTU can be used as a quality assurance tool, providing an evidence-based benchmark against which can be measured actual patterns of practice. It can also be used to assist in determining the adequacy of BT resource allocation.

    Purpose:To determine whether uterine fibroid embolization (UFE) with polyvinyl alcohol (PVA) particles affects fertility in women desiring future pregnancy.Methods:Of 288 patients managed with UFE with PVA particles for uterine myoma or adenomyosis between 1998 and 2001, 94 patients were enrolled in this study. The age range of participants was 20-40 years. The data were collected through review of medical records and telephone interviews. Mean duration of follow-up duration was 35 months (range 22-60 months). Patients using contraception and single women were excluded, and the chance of infertility caused by possible spousal infertility or other factors was disregarded. Contrast-enhanced magnetic resonance imaging was performed in all patients before and after UFE, and the size of PVA particles used was 255-700 {mu}m.Results:Among 94 patients who underwent UFE with PVA, 74 were on contraceptives, 6 had been single until the point of interview, and 8 were lost to follow-up. Of the remaining 6 patients who desired future pregnancy, 5 (83%) succeeded in becoming pregnant (1 patient became pregnant twice). Of a total of 8 pregnancies, 6 were planned pregnancies and 2 occurred after contraception failed. Five deliveries were vaginal, and 2 were by elective cesarean. Artificial abortion was performed in 1 case of unplanned pregnancy. There was 1 case of premature rupture of membrane (PROM) followed by preterm labor and delivery of an infant who was small-for-gestational-age. After UFE, mean volume reduction rates of the uterus and fibroid were 36.6% (range 0 to 62.6%) and 69.3% (range 36.3% to 93.3%), respectively.Conclusion:Although the absolute number of cases was small, UFE with PVA particles ultimately did not affect fertility in the women who underwent the procedure.

    Traditional methods to determine the proportion of cells in S-phase use radiolabeled precursors of DNA, such as {sup 3}H-thymidine, which become incorporated into DNA during its synthesis and are visualized either in tissue sections or in cell preparations by autoradiography. At the Harwell Laboratory the effects of inhaled {alpha}-emitting actinides on the pulmonary alveolar macrophage population of the rodent lung are being studied. For this research the use of an autoradiographic technique to determine the proportion of cells in S-phase is inappropriate, because of the possible presence of competing sources of radioactivity in the cells under investigation. Consequently, an alternative method has been developed. In this method, 5-bromodeoxyuridine (BrdU), an analogue of thymidine, is incorporated into cells undergoing DNA synthesis. Fluorescein-conjugated monoclonal antibodies, highly specific for BrdU substituted DNA, are available commercially and may be used as a probe for BrdU-labeled cells. This technique for identifying cells in S-phase has been described previously for the flow cytometric analysis of cell suspensions and for cells in tissue sections. An adaptation of this technique for use on cytocentrifuge preparations of cells recovered from mouse lung by bronchoalveolar lavage has been developed and its use is described. Some preliminary results of a short-term experiment with CBA/H mice to determine the effects of exposure to cigarette smoke on the DNA synthesis of alveolar macrophages are also included.

    A longitudinal study of 300 women in the puerperium was undertaken in an African population. The aim was to determine the influence of parity on postpartum uterine diameters during involution. The patients were divided into two groups, nulliparous and multiparous based on parity. The uterine diameters were larger in the multiparous group when compared with the nulliparous group. Further analysis revealed positive (Pearson's) correlation between parity and uterine diameters and uterine volume. There was no significant correlation between parity and uterine volume on the 42nd puerperal day. In conclusion, Negroid patients have large uteri, which correlate in size positively with parity.

    Herein is presented a fertility-preserving approach in the management of a uterine arteriovenous malformation (AVM) resistant to endovascular management. The patient had a documented AVM and underwent 2 uterine artery embolization procedures, with subsequent recurrence of symptoms. Doppler ultrasound demonstrated recanalization of the AVM. Ultimately, laparoscopic resection of the AVM was performed after laparoscopic ligation of the uterine arteries. Postoperatively, the patient has remained asymptomatic. Laparoscopic resection of a uterine AVM may offer a fertility-preserving alternative to hysterectomy in patients in whom endovascular management has failed. PMID:25117839

    The purpose of this study was to determine whether there is a correlation between large uterine fibroid diameter, uterine volume, number of vials of embolic agent used and risk of complications from uterine artery embolisation (UAE). This was a prospective study involving 121 patients undergoing UAE embolisation for symptomatic uterine fibroids at a single institution. Patients were grouped according to diameter of largest fibroid and uterine volume. Results were also stratified according to the number of vials of embolic agent used and rate of complications. No statistical difference in complication rate was demonstrated between the two groups according to diameter of the largest fibroid (large fibroids were classified as {>=}10 cm; Fisher's exact test P = 1.00), and no statistical difference in complication rate was demonstrated according to uterine volume (large uterine volume was defined as {>=}750 cm{sup 3}; Fisher's exact test P = 0.70). 84 of the 121 patients had documentation of the number of vials used during the procedure. Patients were divided into two groups, with {>=}4 used defined as a large number of embolic agent. There was no statistical difference between these two groups and no associated increased risk of developing complications. This study showed no increased incidence of complications in women with large-diameter fibroids or uterine volumes as defined. In addition, there was no evidence of increased complications according to quantity of embolic material used. Therefore, UAE should be offered to women with large fibroids and uterine volumes.

    The use of lavage was compared to negative pressure wound therapy (NPWT) with instillation (NPWTi) to assess extent of soft tissue damage, debris removal and environmental cross-contamination susceptibility in three distinct models. Scanning electron microscopy in an ex vivo model showed increased visible tissue trauma from lavage treatment at low and high pressures versus NPWTi, with the degree of trauma relative to the pressure of the irrigant. These results were corroborated in granulating full-thickness excisional swine wounds coated with dextran solution to simulate wound debris. Both low-pressure lavage and NPWTi demonstrated effective cleansing in this model, reducing debris by >90%. However, using three-dimensional photography to evaluate tissue damage by measuring immediate tissue swelling (changes in wound volume and depth) showed significantly greater (P < 0.05) swelling in low-pressure lavage-treated wounds compared with NPWTi-treated wounds. Lastly, bench top wound models were inoculated with fluorescent bacterial particles to assess environmental cross-contamination potential and collected at measured distances after treatment with low-pressure lavage and NPWTi. No evidence of cross-contamination was found with NPWTi, whereas one-half of the particles became 'aerosolised' during low-pressure lavage (P < 0.05). Collectively, these studies demonstrate the effective wound cleansing capabilities of NPWTi without the tissue damage and environmental contamination associated with lavage. PMID:22905800

    Uterine sarcoma, a rare solid tumor in uterus, is difficult to identify in the early stage from some benign uterine tumors, such as uterine fibroids. Hence, uterine sarcoma may be treated in the same way as uterine fibroids; and this may not be found until pathological diagnosis. Consequently, this can lead to tumor’s abdominal spread, planting and local invasive growth, resulting in an early uterine sarcoma, an increased relapse rate after surgery and a decreased survival. Therefore, it’s important to avoid these unintended and iatrogenic complications through an accurate diagnosis and an appropriate surgical approach. The surgical staging and a complete resection of the tumor are both important for patients’ prognosis. In this review, we will discuss the laparoscopic surgery for uterine sarcoma in the early stage and patients’ prognosis. PMID:27503773

    Interleukin-1 (IL-1) is a mediator released by stimulated mononuclear phagocytes that is thought to play an important role in modulating T and B lymphocyte activation as well as in contributing to the febrile response and other inflammatory processes. Circulating mononuclear phagocytes, blood monocytes, readily release IL-1 when stimulated. However, the ability of lung mononuclear phagocytes, alveolar macrophages, to dispose of the large daily burden of inhaled antigens without stimulating an inflammatory response suggests that the release of IL-1 by alveolar macrophages may differ significantly from that of blood monocytes. To evaluate this hypothesis, normal autologous alveolar macrophages, obtained by bronchoalveolar lavage, were compared with blood monocytes for their ability to release IL-1 in response to a standard stimulus, lipopolysaccharide (LPS). Alveolar macrophages were found to be at least 1,000 times less sensitive to LPS than blood monocytes. Furthermore, alveolar macrophages released significantly less IL-1 than blood monocytes (26 +/- 11 vs. 128 +/- 21 U/10(6) cells X 24 h, respectively, after stimulation with 10 micrograms/ml of LPS, P less than 0.001). This difference was not due to the release of substances by macrophages, which inhibited lymphocyte proliferation in response to IL-1, or to degradation of IL-1 by macrophages. Culturing macrophages in the presence of indomethacin and dialysis of macrophage supernatants did not affect the difference, and culturing macrophages with monocytes did not decrease detectable IL-1 activity from the monocytes. The IL-1 produced by the two cell types was indistinguishable by anion-exchange chromatography, gel filtration, and isoelectric focusing. In addition, consistent with the findings for alveolar macrophages, macrophages generated by the in vitro maturation of blood monocytes were also deficient in their ability to release IL-1. These findings suggest that if the population of alveolar macrophages

    Preeclampsia (PE) is a pregnancy-induced hypertension with proteinuria that typically develops after 20 weeks of gestation. A reduction in uterine blood flow causes placental ischemia and placental release of anti-angiogenic factors such as sFlt-1 followed by PE. Although the reduced uterine perfusion pressure (RUPP) model is widely used in rats, investigating the role of genes on PE using genetically engineered animals has been problematic because it has been difficult to make a useful RUPP model in mice. To establish a RUPP model of PE in mice, we bilaterally ligated ovarian vessels distal to ovarian branches, uterine vessels, or both in ICR-strain mice at 14.5 days post coitum (dpc). Consequently, these mice had elevated BP, increased urinary albumin excretion, severe endotheliosis, and mesangial expansion. They also had an increased incidence of miscarriage and premature delivery. Embryonic weight at 18.5 dpc was significantly lower than that in sham mice. The closer to the ligation site the embryos were, the higher the resorption rate and the lower the embryonic weight. The phenotype was more severe in the order of ligation at the ovarian vessels < uterine vessels < both. Unlike the RUPP models described in the literature, this model did not constrict the abdominal aorta, which allowed BP to be measured with a tail cuff. This novel RUPP model in mice should be useful for investigating the pathogenesis of PE in genetically engineered mice and for evaluating new therapies for PE. PMID:27187738

    Uterine stromal cells undergo extensive proliferation and differentiation during postimplantation development, a process known as decidualization. While a range of signaling molecules have been demonstrated to play essential roles in this event, its potential epigenetic regulatory mechanisms remain largely unknown. Retinoblastoma binding protein 7 (Rbbp7) is a protein reported as a core component of many histone modification and chromatin remodeling complexes. In the present study, our in situ hybridization and immunochemistry analysis first reveals a spatiotemporal expression of Rbbp7 in the uterus during the peri-implantation period. Observations of remarkable induction of Rbbp7 expression in uterine stromal cells in response to progesterone-nuclear receptor PR signaling point to its potential physiological significance during postimplantation uterine development. Employing a stealth RNA knockdown approach, combined with primary murine uterine stromal cell culture and an in vitro-induced decidualization model, we further demonstrate that Rbbp7 silencing compromises stromal cell decidualization via attenuating histone H4 acetylation and cyclin D3 expression. The results collectively suggest that Rbbp7 is a potentially functional player regulating normal histone acetylation modification and cyclin D3 expression in stromal cells during postimplantation decidual development.

    The objective was to examine uterine artery hemodynamics and maternal serum profiles in pregnant heifers supplemented with dietary melatonin (MEL) or no supplementation (CON). In addition, melatonin receptor-mediated responses in steroid metabolism were examined using a bovine endometrial epithelial culture system. Twenty singleton pregnant Holstein heifers were supplemented with 20 mg of melatonin (n = 10) or no melatonin supplementation (control; n = 10) from days 190 to 262 of gestation. Maternal measurements were recorded on days 180 (baseline), 210, 240, and 262 of gestation. Total uterine blood flow was increased by 25% in the MEL-treated heifers compared with the CON. Concentrations of progesterone were decreased in MEL vs CON heifers. Total serum antioxidant capacity was increased by 43% in MEL-treated heifers when compared with CON. Activity of cytochrome P450 1A, 2C, and superoxide dismutase was increased in bovine endometrial epithelial cells treated with melatonin, whereas the melatonin receptor antagonist, luzindole, negated the increase in cytochrome P450 2C activity. Moreover, estradiol or progesterone treatment altered bovine uterine melatonin receptor expression, which could potentiate the melatonin-mediated responses during late gestation. The observed increase in total uterine blood flow during melatonin supplementation could be related to its antioxidant properties. Compromised pregnancies are typically accompanied by increased oxidative stress; therefore, melatonin could serve as a therapeutic supplementation strategy. This could lead to further fetal programming implications in conjunction with offspring growth and development postnatally. PMID:26641925

    We examined the expression pattern of hyaluronan synthase (HAS) mRNAs in the uterine cervix of pregnant mice. The expression levels of HAS-1 and -2 mRNAs peaked at delivery, whereas that of HAS-3 mRNA peaked on the 15th day of pregnancy. The regulation of HAS mRNA expression was examined in pregnant mouse uterine cervical fibroblasts. The expression of HAS-1, -2, and -3 mRNAs was significantly augmented by interleukin-1beta (IL-1beta). Progesterone significantly interfered with expression of HAS-1 and -2 mRNAs, but significantly increased the expression of HAS-3 mRNA. Low-molecular-weight hyaluronan significantly enhanced only the expression of HAS-1 mRNA. These results indicate that HAS in the uterine cervix is regulated in a complex manner by IL-1beta, progesterone, and low-molecular-weight hyaluronan, of which changes in the cervical tissue and serum closely participate in uterine cervical ripening and/or inflammation.

    Uterine fibroids are common but their role in infertility and effect on embryo implantation is unclear. There is evidence that submucosal fibroids are associated with poor reproductive outcome and that treatment with myomectomy is associated with an improvement in pregnancy rates. Various theories have been proposed to explain this relationship. Fibroids cause a mechanical distortion of the endometrial cavity-their presence may alter gamete and embryo transport (due to blockage of the tubal ostia or by altering uterine contractility and peristalsis) and subsequent embryo implantation (due to compression of the endometrium). They may lead to disruption of the junctional zone within the myometrial layer, affecting general uterine function in the initial stages of embryo invasion and later placentation. Altered vasculature due to the abnormal expression of angiogenic factors by uterine fibroids (such as basic fibroblast growth factor and platelet-derived growth factor) could play a role in a reduced implantation rate in patients with fibroids. Similarly, changes in the endometrium mediated by inflammation and factors involved in the process of fibrosis (such as transforming growth factor) could also have a detrimental effect. In addition, fibroids may affect gene expression pattern in the endometrium (such as HOXA10), disrupting the window of implantation. The supporting evidence for these theories is discussed in this review. PMID:17960533

    During delivery, quantitative information on the uterine activity can be provided by internal uterine pressure (IUP) recordings using an invasive intrauterine pressure catheter (IUPC). The electrohysterogram, which measures the electrical signal that drives the mechanical contraction of the uterine muscle and the consequent IUP increase, is recorded by electrodes placed on the abdomen. Recent work demonstrated the possibility of reliably estimating the IUP noninvasively by electrohysterographic (EHG) signal analysis. To further improve the accuracy of IUP estimates, we investigated the use of three nonlinear functions for modeling the relationship between the electrical activation measured by the EHG signal and the mechanical response of the uterine muscle. The feature employed for obtaining a first estimate of the IUP is the unnormalized first statistical moment of the EHG spectrum. The relationship between the extracted feature and the IUP is modeled by a second-order polynomial, a logarithmic, and an exponential function. For validation, the IUPC and the EHG signals were recorded on nine women in labor. A second-order polynomial model already provided estimates that are highly correlated with the IUPC signal (r = 0.73). However, the logarithmic model resulted to be the most accurate, especially in terms of root mean squared error (RMSE = 5.13 mmHg). PMID:19963667

    Acid extracts of rat, bovine and rabbit uterus stimulated glucose transport, measured by phosphorylation of 2-deoxyglucose and DNA synthesis, measured by {sup 3}H-thymidne incorporation, in uterine tumor cells and in primary cultures of rat uterine cells. The stimulation of glucose transport was of the same magnitude and followed the same time course as estradiol stimulation in vivo. Uteri from estradiol-treated rat uteri contained 4 times more glucose transport-stimulating activity as control uteri. DNA synthetic activity in rat uterine homogenates was elevated 3-fold within 18-24 h after estradiol injection. Gel filtration showed molecular weight heterogeneity with activity eluting between 10-30 kDA. Both activities were acid and heat stable, were reduced by trypsin but not by dextran-coated charcoal. The effect of purified growth factors on DNA synthesis in primary cultures of rat uterine cells was examined. Epidermal growth factor (EGF), basic fibroblasts growth factor (bFGF), and transforming growth factor-{beta} (TGF{beta}) had no effect on {sup 3}H-thymidine incorporation.

    Preeclampsia (PE) is a pregnancy-induced hypertension with proteinuria that typically develops after 20 weeks of gestation. A reduction in uterine blood flow causes placental ischemia and placental release of anti-angiogenic factors such as sFlt-1 followed by PE. Although the reduced uterine perfusion pressure (RUPP) model is widely used in rats, investigating the role of genes on PE using genetically engineered animals has been problematic because it has been difficult to make a useful RUPP model in mice. To establish a RUPP model of PE in mice, we bilaterally ligated ovarian vessels distal to ovarian branches, uterine vessels, or both in ICR-strain mice at 14.5 days post coitum (dpc). Consequently, these mice had elevated BP, increased urinary albumin excretion, severe endotheliosis, and mesangial expansion. They also had an increased incidence of miscarriage and premature delivery. Embryonic weight at 18.5 dpc was significantly lower than that in sham mice. The closer to the ligation site the embryos were, the higher the resorption rate and the lower the embryonic weight. The phenotype was more severe in the order of ligation at the ovarian vessels < uterine vessels < both. Unlike the RUPP models described in the literature, this model did not constrict the abdominal aorta, which allowed BP to be measured with a tail cuff. This novel RUPP model in mice should be useful for investigating the pathogenesis of PE in genetically engineered mice and for evaluating new therapies for PE. PMID:27187738

    Uterine arteries embolization (UAE) is a recent technique that aims, by means of particles injected percutaneously, to stifle fibroids (leiomyomas). This treatment is non-invasive, compared with uterine ablation, but generates pelvic pain for a few days. A strategy to reduce the post-embolization pain would be to use calibrated embolization microspheres preloaded with a non-steroidal inflammatory drug (NSAID). In this study, we first compared four drugs, all active at low concentration on cyclooxygenase-2, i.e. ketoprofen, sodium diclofenac, flurbiprofen and niflumic acid (NFA), for their capacity to be loaded on resorbable embolization microspheres (REM) 500-700μm. NFA had the highest capacity of loading (5mg/mL) on resorbable microspheres. Then, we evaluated in vitro the NFA release profiles from REM having various degradation times of one, two or five days. NFA release was biphasic, with an initial burst (about 60% of the loading) followed by a sustained release that correlated significantly to REM's hydrolysis (rho=0.761, p<0.0001). For each group of beads, the size distribution was not modified by the loading of NFA and their delivery through microcatheter was not impaired by the drug. NFA eluted from REM inhibited the synthesis of prostaglandin E2 from rabbit uterus explants. In summary, NFA is loadable on REM in significant amount and its delivery can be tuned according to the degradation rate of REM to provide an antalgic effect for a few days after UAE. PMID:27374196

    Caesarean section (CS) results in the occurrence of the phenomenon ‘niche’. A ‘niche’ describes the presence of a hypoechoic area within the myometrium of the lower uterine segment, reflecting a discontinuation of the myometrium at the site of a previous CS. Using gel or saline instillation sonohysterography, a niche is identified in the scar in more than half of the women who had had a CS, most with the uterus closed in one single layer, without closure of the peritoneum. An incompletely healed scar is a long-term complication of the CS and is associated with more gynaecological symptoms than is commonly acknowledged. Approximately 30% of women with a niche report spotting at 6–12 months after their CS. Other reported symptoms in women with a niche are dysmenorrhoea, chronic pelvic pain and dyspareunia. Given the association between a niche and gynaecological symptoms, obstetric complications and potentially with subfertility, it is important to elucidate the aetiology of niche development after CS in order to develop preventive strategies. Based on current published data and our observations during sonographic, hysteroscopic and laparoscopic evaluations of niches we postulate some hypotheses on niche development. Possible factors that could play a role in niche development include a very low incision through cervical tissue, inadequate suturing technique during closure of the uterine scar, surgical interventions that increase adhesion formation or patient-related factors that impair wound healing or increase inflammation or adhesion formation.

    A meta-analysis was conducted to assess the effects of laparoscopic versus minilaparotomic myomectomy on uterine leiomyoma in premenopausal women. We performed a computerized search of MEDLINE, Embase, and the Cochrane Library from 1996 to 2104. From 711 studies, a total of 4 studies met our inclusion criteria, and a meta-analytic technique was used to study the 4 randomized controlled trials involving 577 women with symptomatic uterine leiomyoma. Compared with the minilaparotomic myomectomy group, the laparoscopic myomectomy group showed a significantly less hemoglobin drop and blood loss, lower postoperative analgesic use, shorter duration of postoperative ileus, shorter hospitalization days and recovery time, and higher levels in the pregnancy rate per cycle and the live birth rate per cycle. There was no significant difference between the 2 groups regarding the operating time, complications, laparotomic conversion rate, cumulative pregnancy rate, cumulative live birth rate, and abortion rates. When performed by experienced surgeons in selected patients (e.g., symptomatic leiomyoma women who have the indications for surgery), laparoscopic myomectomy is a better choice than minilaparotomic myomectomy.

    During labor, uterine contractions can cause temporary oxygen deficiency for the fetus. In case of severe and prolonged oxygen deficiency this can lead to asphyxia. The currently used technique for detection of asphyxia, cardiotocography (CTG), suffers from a low specificity. Recent studies suggest that analysis of fetal heart rate variability (HRV) in addition to CTG can provide information on fetal distress. However, interpretation of fetal HRV during labor is difficult due to the influence of uterine contractions on fetal HRV. The aim of this study is therefore to investigate whether HRV features differ during contraction and rest periods, and whether these differences can improve the detection of asphyxia. To this end, a case-control study was performed, using 14 cases with asphyxia that were matched with 14 healthy fetuses. We did not find significant differences for individual HRV features when calculated over the fetal heart rate without separating contractions and rest periods (p  >  0.30 for all HRV features). Separating contractions from rest periods did result in a significant difference. In particular the ratio between HRV features calculated during and outside contractions can improve discrimination between fetuses with and without asphyxia (p  <  0.04 for three out of four ratio HRV features that were studied in this paper).

    Objective: To describe a novel use for a tracheobronchial stent to maintain patency after vaginal septum excision in a patient with an obstructed hemivagina and uterine didelphys. Design: Description of a novel technique Setting: University-affiliated Children’s Hospital Patient: One patient with an obstructed hemivagina and uterine didelphys who presented with hematometria and hematocolpos. Intervention: In order to maintain patency and decrease stenosis risk after vaginal septum excision, a coated tracheobronchial stent was deployed and left in place for 6 weeks. Main Outcome Measure: To evaluate ease of stent placement and removal, re-epithelialization and patency of the neo-vagina, and post-operative assessment of pain and recurrent obstruction. Results: The tracheobroncheal stent was easily positioned and deployed with vaginoscopic guidance. Six weeks later it was removed without any tissue in-growth or granulation tissue noted. The vaginal walls were nicely epithelialized. Twelve months post-operatively the patient remained pain free with regular cycles and no evidence of obstruction or abnormality on ultrasound. Conclusion: Use of a coated tracheobronchial stent to maintain patency after septum excision in a patient with an obstructed hemivagina presents a safe, easy and effective option to diminish stenosis risk and avoid infectious complications or hysterectomy.

    Clinical practice requires improved techniques to assess human cervical tissue properties, especially at the internal os, or orifice, of the uterine cervix. Ultrasound elastography (UE) holds promise for non-invasively monitoring cervical stiffness throughout pregnancy. However, this technique provides qualitative strain images that cannot be linked to a material property (e.g., Young's modulus) without knowledge of the contact pressure under a rounded transvaginal transducer probe and correction for the resulting non-uniform strain dissipation. One technique to standardize elastogram images incorporates a material of known properties and uses one-dimensional, uniaxial Hooke's law to calculate Young's modulus within the compressed material half-space. However, this method does not account for strain dissipation and the strains that evolve in three-dimensional space. We demonstrate that an analytical approach based on 3D Hertzian contact mechanics provides a reasonable first approximation to correct for UE strain dissipation underneath a round transvaginal transducer probe and thus improves UE-derived estimates of tissue modulus. We validate the proposed analytical solution and evaluate sources of error using a finite element model. As compared to 1D uniaxial Hooke's law, the Hertzian contact-based solution yields significantly improved Young's modulus predictions in three homogeneous gelatin tissue phantoms possessing different moduli. We also demonstrate the feasibility of using this technique to image human cervical tissue, where UE-derived moduli estimations for the uterine cervix anterior lip agreed well with published, experimentally obtained values. Overall, UE with an attached reference standard and a Hertzian contact-based correction holds promise for improving quantitative estimates of cervical tissue modulus. PMID:26003483

    This paper describes changes in spontaneous myometrial activity around estrus, factors that affect myometrial activity, and the possible role of uterine contractions in the process of (artificial) insemination, sperm transport and fertilization. Myometrial activity in the sow increases during estrus. The activity is myogenic in origin, but several factors have been shown to affect myometrial activity. Natural mating stimulates uterine contractions through several mechanisms. The presence of a boar, rather than the act of mating, induces central oxytocin release in the sow and thus increases uterine activity. Estrogens in the ejaculate of a boar can trigger prostaglandin release by the endometrium and thus increase uterine activity. Tactile stimulation of the genital tract (cervix) or tactile stimulation of the back and flanks of the sow during artificial insemination does not cause a release of oxytocin. There is hardly any evidence for the effects of these latter stimuli on uterine activity, and if they are present at all, the effects are very small. Evidence for the effects of synthetic boar odor on oxytocin release and/or uterine activity is inconsistent. The mere presence of a boar during insemination, in contrast, clearly stimulates uterine activity through the release of oxytocin. Hormonal stimulation (intrauterine) of uterine activity with estrogens, prostaglandins, or oxytocins before, during or after insemination generally improves fertilization rate, especially in situations with reduced fertility. Therefore, uterine contractions are believed to play an important role in the transport of sperm cells to the oviducts after insemination. Whether uterine contractions are absolutely necessary for sperm transport through the uterine horns, however, is not clear. Intensive stimulation of uterine contractions using hormones can also reduce the fertilization rate, probably by increasing the reflux of sperm cells during insemination. In this respect, the presence

    The anthors studied the morphological features of uterine adenocarcinoma using immunohistochemical methods. The endometrial tissue was studed resulting from surgery - hysterectomy with oophorectomy in 103 patients aged 45-76 years with a clinical diagnosis of endometrial cancer. To exclude false-positive and false-negative results, we carry out same investigation on 12 patients with morphological diagnosis easy-glandular hyperplasia of the endometrium. The results showed that the endometrioid adenocarcinomas exhibit the high and moderate expression of estrogen and progesterone receptors and low rate of the proliferation marker Ki-67. For serous-paapillary andenocarcionoma of the uterine body the negative ER-PR-receptor over expression phenotype and proliferation marker Ki-67 superexpression are characteristic. The results showed that in a simple-glandular endometrial hyperplasia is determined a moderate expression of estrogen and progesterone receptors, as for the Ki-67 proliferation marker an expression was found only in the single arears with an average of 5-8% of findings. Based at shis study it may be concluded thate the use of immunohistochemical studies particularly a detection of negative estrogen and progesterone resceptor phenotype and high expression of the proliferation marker Ki-67 is an additional defferential diagnostic eriterion for the diagnosis of serous papillary adenocarcinoma of the uterine body thet will ensure adepuate therapeutis approach to patients suffering from this disorder.

    Previous studies have shown that chronic administration of oestrogen during postnatal rat development dramatically reduces the total content of noradrenaline in the uterine horn, abolishes myometrial noradrenergic innervation and reduces noradrenaline-fluorescence intensity of intrauterine perivascular nerve fibres. In the present study we analysed if this response is due to a direct and selective effect of oestrogen on the uterine noradrenaline-containing sympathetic nerves, using the in oculo transplantation method. Small pieces of myometrium from prepubertal rats were transplanted into the anterior eye chamber of adult ovariectomised host rats. The effect of systemic chronic oestrogen treatment on the reinnervation of the transplants by noradrenaline-containing sympathetic fibres from the superior cervical ganglion was analysed on cryostat tissue sections processed by the glyoxylic acid technique. In addition, the innervation of the host iris was assessed histochemically and biochemically. The histology of the transplants and irises was examined in toluidine blue-stained semithin sections. These studies showed that after 5 wk in oculo, the overall size of the oestrogen-treated transplants was substantially larger than controls, and histology showed that this change was related to an increase in the size and number of smooth muscle cells within the transplant. Chronic oestrogen treatment did not provoke trophic changes in the irideal muscle. Histochemistry showed that control transplants had a rich noradrenergic innervation, associated with both myometrium and blood vessels. Conversely, in oestrogen-treated transplants only occasional fibres were recognised, showing a reduced NA fluorescence intensity. No changes in the pattern and density of innervation or in the total content of noradrenaline of the host irises were detected after chronic exposure to oestrogen. We interpreted these results to indicate that the effects of oestrogen on uterine noradrenaline

    Objective To determine if neurofilament (NF) is expressed in the endometrium and the lesions of myomas and adenomyosis, and to determine their correlation. Methods Histologic sections were prepared from hysterectomies performed on women with adenomyosis (n=21), uterine myoma (n=31), and carcinoma in situ of the uterine cervix. Full-thickness uterine paraffin blocks, which included the endometrium and myometrium histologic sections, were stained immunohistochemically using the antibodies for monoclonal mouse antihuman NF protein. Results NF-positive cells were found in the endometrium and myometrium in 11 women with myoma and in 7 with adenomyosis, but not in patients with carcinoma in situ of uterine cervix, although the difference was statistically not significant. There was no significant difference between the existence of NF-positive cells and menstrual pain or phases. The NF-positive nerve fibers were in direct contact with the lesions in nine cases (29.0%) of myoma and in five cases (23.8%) of adenomyosis. It was analyzed if there was a statistical significance between the existence of NF positive cells in the endometrium and the expression of NF-positive cells in the uterine myoma/adenomyosis lesions. When NF-positive cell were detected in the myoma lesions, the incidence of NF-positive nerve cells in the eutopic endometrium was significantly high. When NF-positive cell were detected in the basal layer, the incidence of NF-positive nerve cells in the myoma lesions and adenomyosis lesions was significantly high. Conclusion We assume that NF-positive cells in the endometrium and the myoma and adenomyosis lesions might play a role in pathogenesis. Therefore, more studies may be needed on the mechanisms of nerve fiber growth in estrogen-dependent diseases. PMID:25798429

    Foxl2 codes for a forkhead/HNF3 transcription factor essential for follicular maturation and maintenance of ovarian identity. FOXL2 mutations are associated with Blepharophimosis, Ptosis and Epicanthus inversus Syndrome (BPES) characterized by eyelid malformations (types I and II) and premature ovarian insufficiency (type I). We show that Foxl2 is not only expressed by the ovary, but also by other components of the mouse female reproductive tract, including the uterus, the cervix and the oviduct. In the uterus, Foxl2 expression is first observed in the neonatal mesenchyme and, during uterine maturation, persists in the stroma and in the deep inner myometrial layer (IML). In the adult, Foxl2 is expressed in the differentiated stromal layer, but no longer in the myometrium. Conditional deletion of Foxl2 in the postnatal (PN) uterus using Progesterone Receptor-cre (Pgr(cre/+)) mice results in infertility. During PN uterine maturation Pgr(cre/+); Foxl2(flox/flox) mice present a severely reduced thickness of the stroma layer and an hypertrophic, disorganized IML. In adult Pgr(cre/+); Foxl2(flox/flox) mice a supplementary muscular layer is present at the stroma/myometrium border and vascular smooth muscle cells fail to form a coherent layer around uterine arteries. Wnt signalling pathways play a central role in uterine maturation; in Pgr(cre/+); Foxl2(flox/flox) mice, Wnt genes are deregulated suggesting that Foxl2 acts through these signals. In humans, thickening of the IML (also called "junctional zone") is associated with reduced fertility, endometriosis and adenomyosis. Our data suggest that Foxl2 has a crucial role in PN uterine maturation and could help to understand sub-fertility predisposition in women. PMID:25687138

    Embryonic mortality in cows is at least in part caused by failure of pregnancy recognition (PR). Evidence has shown that bovine viral diarrhoea virus (BVDV) infection can disrupt pregnancy. Prostaglandins (PG) play important roles in many reproductive processes, such as implantation. The aim of this study was to investigate the effect of BVDV infection on uterine PG production and PR using an in vitro PR model. Bovine uterine endometrial cells isolated from ten BVDV-free cows were cultured and treated with 0 or 100ng/mL interferon-τ (IFNT) in the absence or presence of non-cytopathic BVDV (ncpBVDV). PGF2α and PGE2 concentrations in the spent medium were measured using radioimmunoassays, and in the treated cells expression of the genes associated with PG production and signalling was quantified using qPCR. The results showed that the IFNT challenge significantly stimulated PTGS1 and PTGER3 mRNA expression and PGE2 production; however, these stimulatory effects were neutralised in the presence of ncpBVDV infection. ncpBVDV infection significantly increased PTGS1 and mPGES1 mRNA expression and decreased AKR1B1 expression, leading to increased PGE2 and decreased PGF2α concentrations and an increased PGE2:PGF2α ratio. The other tested genes, including PGR, ESR1, OXTR, PTGS2, PTGER2 and PTGFR, were not significantly altered by IFNT, ncpBVDV or their combination. Our study suggests that BVDV infection may impair PR by (1) inhibiting the effect of IFNT on uterine PG production and (2) inducing an endocrine switch of PG production from PGF2α to PGE2 to decrease uterine immunity, thereby predisposing the animals to uterine disease.

    Purpose. Bilateral uterine artery embolization (UAE) is considered necessary to provide effective treatment for symptomatic uterine fibroids. Occasionally, only unilateral embolization is performed, and this study evaluates these outcomes. Materials and Methods. As part of a prospective observational study of more than 1600 patients treated with UAE since 1996, there have been 48 patients in whom unilateral embolization has been performed. This study retrospectively reviews clinical response as assessed by our standard questionnaire and radiological response assessed by either magnetic resonance imaging or ultrasound. Results. Two principal groups emerged: the largest, where only the dominant unilateral arterial supply was electively embolized (30 patients); and the second, where there was technical failure to catheterize the second uterine artery as a result of anatomical constraints (12 patients). Favorable clinical response with a reduction in menorrhagia at 1 year was seen in 85.7% (18/21) of those patients with a dominant arterial supply to the fibroid(s). In contrast, in those patients where there was technical failure to embolize one uterine artery, there was a high rate of clinical failure requiring further intervention in 58.3% (7/12). Comparison of the technical failure group with the dominant uterine artery group demonstrated a statistically significant (Fisher's exact test) difference in the proportion of patients with evidence of persistent fibroid vascularity (p < 0.001) and requiring repeat intervention (p < 0.01). Conclusion. We conclude that unilateral UAE can achieve a positive clinical result in the group of patients where there is a dominant unilateral artery supplying the fibroid(s), in contrast to the poor results seen following technical failure.

Results The meta-analysis included 28 studies, with a total of 20,714 patients. For the overall survival rate of all stages, the results demonstrated that positive pre-resection, post-resection and pooled PLC were associated with unfavorable survival: hazard ratio (HR) 2.89 (95% confidence interval [CI] 2.48–3.37), 2.70 (1.90–3.83), and 2.89 (2.52–3.31), respectively. For the stage I survival rate, the combined results also suggested that positive pre-resection, post-resection and pooled PLC were associated with unfavorable survival: HR 3.29 (95% CI 2.55–4.25), 4.85 (2.31–10.20), and 3.16 (2.53–3.94), respectively. Furthermore, a meta-analysis of 14 studies included 14,279 patients showed that positive pre-resection, post-resection and pooled PLC were associated with an increased risk of overall recurrence: risk ratio (RR) 2.45 (95% CI 1.91–3.15), 2.37 (1.11–5.09), and 2.37 (95% CI 2.00–2.80), respectively. Positive PLC was also associated with a high pleural recurrence (RR 4.77; 95% CI 3.13–7.26) or distant recurrence (RR 2.33; 95% CI 1.65–3.29). Conclusions Both positive pre- resection and post-resection PLC are associated with not only higher tumor recurrence but also unfavorable survival outcomes in patients with lung cancer resection. This technique can therefore act as a strong prognostic factor for tumor recurrence and adverse survival rates. PMID:27458805

    Secretory leukocyte proteinase inhibitor (SLPI) and alpha1-proteinase inhibitor (alpha1(PI)) cannot fully explain the total neutrophil elastase (NE) inhibitory capacity detected in bronchoalveolar lavage (BAL) fluid, suggesting the existence of other NE inhibitor(s). In the present study, we measured the concentrations of elafin, a newly described, low-molecular-weight serine proteinase inhibitor, SLPI, and alpha1(PI) in BAL fluids from eight healthy subjects, 13 asymptomatic farmers, seven farmers with active farmer's lung (FL), and seven farmers with previous (Ex) FL. In addition to SLPI and alpha1(PI), elafin was present in BAL fluids from control subjects and asymptomatic farmers, 13 (7-31) and 12 (7-67) mmol/mol of albumin (median and range) respectively. Elafin concentration increased significantly to 105 (38-207) mmol/mol of albumin in farmers with active FL and was also elevated in farmers with Ex FL. Elafin levels were highly correlated with lung inflammatory cell numbers, especially lymphocytes, and the decrease in single-breath diffusion capacity (DLCO). Elafin and SLPI were linked to yet uncharacterized proteins in BAL fluids. In conclusion, elafin is a constituent of BAL fluid from normal subjects and is found in enhanced concentrations in FL and in farmers with lymphocytic alveolitis. This suggests that elafin may play a role in lung homeostasis and inflammation. PMID:8887613

    Background. There is no gold standard test for diagnosis of gastroesophageal reflux disease (GERD) associated infantile wheezing. Objectives. To evaluate the value of bronchoalveolar lavage (BAL) pepsin assay in diagnosis of GERD in wheezy infants. Methods. Fifty-two wheezy infants were evaluated for GERD using esophageal combined impedance-pH (MII-pH) monitoring, esophagogastroduodenoscopy with esophageal biopsies, and BAL pepsin. Tracheobronchial aspirates from 10 healthy infants planned for surgery without history of respiratory problems were examined for pepsin. Results. Wheezy infants with silent reflux and wheezy infants with typical GERD symptoms but normal MII-pH had significantly higher BAL pepsin compared to healthy control (45.3 ± 8.6 and 42.8 ± 8 versus 29 ± 2.6, P < 0.0001 and P = 0.011, resp.). BAL pepsin had sensitivity (61.7%, 72 %, and 70%) and specificity (55.5%, 52.9%, and 53%) to diagnose GERD associated infantile wheeze compared to abnormal MII-pH, reflux esophagitis, and lipid laden macrophage index, respectively. Conclusion. A stepwise approach for assessment of GERD in wheezy infants is advised. In those with silent reflux, a trial of antireflux therapy is warranted with no need for further pepsin assay. But when combined MII-pH is negative despite the presence of typical GERD symptoms, pepsin assay will be needed to rule out GERD related aspiration. PMID:27516725

  7. Pulmonary alveolar proteinosis with myeloproliferative syndrome with myelodysplasia: bronchoalveolar lavage reduces white blood cell count.

    Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by surfactant component accumulation in the alveolar space. Primary PAP is likely an autoimmune disorder caused by antibodies to granulocyte-macrophage colony stimulating factor (GM-CSF). When an underlying disease causes PAP, this is called secondary PAP. Hematologic malignancies are an important cause of secondary PAP. As the pathogenesis of primary PAP has become more fully understood, improvements in diagnostic and therapeutic approaches have followed. However, when PAP is secondary to an underlying hematologic malignancy, much remains unclear. Here we describe for the first time a patient with hybrid myelodysplastic syndrome/myeloproliferative syndrome and PAP who had a marked decrease in her white blood cell count following a transbronchial biopsy accompanied by bronchoalveolar lavage (BAL). Similar significant decreases in WBC count accompanied clinical improvement following two unilateral BALs. Given that patients with pulmonary alveolar proteinosis frequently have elevated GM-CSF in bronchoalveolar fluid, this observation provides a unique vantage point to understand the pathophysiology of secondary PAP.

    Bronchoalveolar lavage using flexible fibreoptic bronchoscope was carried out in 50 patients 1-2 1/2 yr after exposure to the 'toxic gas' at Bhopal. Thirty six patients in the analysis were categorised into 3 groups (viz., mild, moderate and severe), depending upon the severity of exposure. There was an increase in cellularity in the lower respiratory tract (alveolitis) of the severely exposed patients (in both smokers and non-smokers), compared to normals (P less than 0.05). The increase in cellularity in severely exposed non-smokers was due to abnormal accumulation of macrophages (P less than 0.01), and in severely exposed smokers, to macrophages (P less than 0.01) and neutrophils (P less than 0.05). Mild and moderately exposed patients did not show significant change in cellularity in lower respiratory tract, compared to normal individuals (P greater than 0.2). There was a trend towards increasing cellularity, as the severity increased (P less than 0.0001) and higher numbers of total cells were seen in severely exposed smokers, suggesting that smoking is a risk factor. It appears, therefore, that subjects severely exposed to the toxic gas at Bhopal may have a subclinical alveolitis characterised by accumulation and possibly activation of macrophages in the lower respiratory tract. Smokers, who were exposed to the gas had in addition, accumulation of neutrophils. PMID:2628309

    Chemical reactions with unsaturated phospholipids in the respiratory tract lining fluid have been identified as one of the first important steps in the mechanisms mediating environmental ozone toxicity. As a consequence of these reactions, complex mixtures of oxidized lipids are generated in the presence of mixtures of non-oxidized naturally occurring phospholipid molecular species, which challenge methods of analysis. Untargeted mass spectrometry and statistical methods were employed to approach these complex spectra. Human bronchoalveolar lavage (BAL) was exposed to low levels of ozone and samples, with and without derivatization of aldehydes, were analyzed by liquid chromatography electrospray ionization tandem mass spectrometry. Data processing was carried out using principal component analysis (PCA). Resulting PCA score plots indicated an ozone dose-dependent increase, with apparent separation between BAL samples exposed to 60 ppb ozone and non-exposed BAL samples, and a clear separation between ozonized samples before and after derivatization. Corresponding loadings plots revealed that more than 30 phosphatidylcholine (PC) species decreased due to ozonation. A total of 13 PC and 6 phosphatidylglycerol oxidation products were identified with the majority being structurally characterized as chain-shortened aldehyde products. This method exemplifies an approach for comprehensive detection of low abundance, yet important, components in complex lipid samples. PMID:25575758

    Sarcoidosis is a systemic inflammatory disease with abnormally high angiogenic activity of inflammatory cells. Reumaherb preparation consisting of three herbs: Echinacea purpurea, Harpagophytum procumbens, and Filipendula ulmaria, and it exerts anti-inflammatory, antioxidant, and analgesic activity and stimulates regenerative and immunological processes. The aim of this paper was to estimate the effect of Reumaherb on immunological angiogenesis induced by bronchoalveolar lavage (BAL) cells collected from six patients with sarcoidosis and grafted into Balb/c mice skin. After grafting, the animals were fed for three days with 0.6 or 1.2 mg of Reumaherb (calculated from recommended human daily dose) daily, suspended in 40 µl of water, or 40 µl of water alone (control group). A significant reduction of newly formed blood vessels was obtained in four cases for 1.2 mg and in three cases for 0.6 mg daily dose of this remedy. Thus, we hypothesise that Reumaherb promotes anti-angiogenic activity and may potentially be used in diseases associated with excessive blood vessel formation. PMID:27095919

    Objective This study was designed to examine the mutual relationship between 8-isoprostane in exhaled breath condensate (EBC) and superoxide anion generation by bronchoalveolar lavage fluid (BALF) cells in patients with sarcoidosis. Design About 29 patients with sarcoidosis, 34 healthy never smokers (control group for EBC) and 15 healthy never smokers (control group for BAL) were examined. EBC was collected directly before bronchoscopy. 8-Isoprostane was measured by ELISA, and superoxide anion by colorimetry. Results Exhaled breath condensate 8-isoprostane is increased in sarcoidosis (median, 25–75 percentile): 2.50; 2.50–3.90 versus 6.20; 2.50–16.95 pg/ml, p ≤ 0.05). Spontaneous superoxide anion release from BALF cells was significantly elevated only in patients with a high percentage of lymphocytes in BALF (6.42 ± 1.24 vs. 23.52 ± 4.30 nmol/106 cells, p ≤ 0.01). There were no correlations between 8-isoprostane and spontaneous or stimulated superoxide anion release. Conclusions We confirmed higher concentrations of EBC 8-isoprostane in sarcoidosis and higher spontaneous release of superoxide anion from BALF cells in patients with sarcoidosis. The increase of EBC 8-isoprostane is not directly related to superoxide anion released from BALF cells. PMID:20521080

    Between 2001-2002; in 62 cases, 33 (53%) male, 29 (47%) female, mean age 51.4 +/- 18.1 years) bronchoalveolar lavage (BAL) was performed for diagnosis of opportunistic pulmonary infection and specimens were evaluated for results of microbiological examinations. There was hematological malignancy in 18 (29%) and solid organ malignancy in 13 (21%) cases. Thirty-one (50%) cases were immunocompromised for reasons other than malignancy. By endoscopic evaluation endobronchial lesion was seen in 2 (3%) cases, indirect tumor signs were seen in 2 (3%) cases and signs of infection were seen in 11 (18%) cases. Forty-even (76%) cases were endoscopically normal. Acid-fast bacilli (AFB) direct examination was positive in 3 (5%) cases. In 4 (6%) cases mycobacterial culture was positive, Mycobacterium tuberculosis-polymerase chain reaction (PCR) was also positive in these four cases. Examination of gram-stained smears for bacteria was associated with infection in 14 (23%) cases. Bacteriologic cultures were positive for single potential pathogen in 10 (16%) cases, and for mixed pathogens in 7 (11%) cases for a total number of 17 (27%). Fungal cultures were positive in 3 (5%) cases all of which had hematological malignancy. As a result in 24 (39%) cases microbiological agent of infection is determined: in four mycobacteria, in 17 bacteria other than mycobacteria and in three fungi. PMID:17001542

    Early detection of the cyanobacterium Pseudomonas aeruginosa in the lungs of young children with cystic fibrosis (CF) is considered the key to delaying chronic pulmonary disease. We investigated whether cyanide in bronchoalveolar lavage (BAL) fluid could be used as an early diagnostic biomarker of infection. Cyanide was measured in 226 BAL samples (36 P. aeruginosa infected) obtained from 96 infants and young children with CF participating in an early surveillance programme involving annual BAL. Cyanide was detected in 97.2% of P. aeruginosa infected and 60.5% of uninfected samples. Cyanide concentrations were significantly higher in BALs infected with P. aeruginosa (median (25th-75th percentile) 27.3 (22.1-33.3) μM) than those which were not (17.2 (7.85-23.0) μM, p<0.001). The best sensitivity, specificity, positive and negative predictive values were obtained with a cut-off concentration of 20.6 μM, and were 83%, 66%, 32% and 96%, respectively. Neutrophil number in BAL was a significant predictor of cyanide concentration (p<0.001). Cyanide concentration can distinguish between P. aeruginosa infected and uninfected BALs as a group, but not individually; therefore, cyanide is a poor diagnostic biomarker of P. aeruginosa infection. Cyanide levels in BAL are related to the level of neutrophilic inflammation. PMID:20562125

  14. The thermal effects of lavage on 57 ox femoral heads prepared for hip resurfacing arthroplasty

    PubMed Central

    2013-01-01

    Background and purpose Previously, we have documented surface temperatures recorded by thermography great enough to cause osteonecrosis of the femoral head during hip resurfacing. We now performed an in vitro investigation with 3 questions: (1) whether water irrigation reduced bone surface temperature, (2) whether external bone temperatures were similar to core temperatures, and (3) whether blunting of the reamer affected temperature generation. Methods Using an ox-bone model, 57 femoral heads were peripherally reamed. The surface temperatures of bone were measured using a thermal camera and internal bone temperatures were measured using 2 theromocouples. We measured the effects of cooling with water at room temperature and with ice-cooled water. Progressive blunting of reamers was assessed over the 57 experiments. Results Mean and maximum temperatures generated during peripheral reaming were greater when no irrigation was used. Ice-cold saline protected femoral heads from thermal damage. External bone temperatures were much greater than internal temperatures, which were not sufficiently elevated to cause osteonecrosis regardless of lavage. Blunting of the reamer was not found to have a statistically significant effect in this study. Interpretation Cooling with ice-cooled water is recommended. Internal bone temperatures are not elevated despite the high surface temperatures reached during femoral head resurfacing. PMID:24079554

    Candida species, especially C. albicans, are commensals on human mucosal surfaces, but are increasingly becoming one of the important invasive pathogens as seen by a rise in its prevalence in immunocompromised patients and in antibiotic consumption. Thus, an accurate identification of Candida species in patients with pulmonary symptoms can provide important information for effective treatment. A total of 75 clinical isolates of Candida species were obtained from the bronchoalveolar lavage fluid of both immunocompromised and immunocompetent patients with pulmonary symptoms. Candida cultures were identified based on nuclear ribosomal Internal Transcribed Spacer (ITS1-ITS2 rDNA) sequence analysis by polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP). Molecular identification indicated that the isolates belonged predominantly to C. albicans (52%), followed by C. tropicalis (24%), C. glabrata (14.7%), C. krusei (5.3%), C. parapsilosis (1.3%), C. kefyr (1.3%) and C. guilliermondii (1.3%). Given the increasing complexity of disease profiles and their management regimens in diverse patients, rapid and accurate identification of Candida species can lead to timely and appropriate antifungal therapy.

    We examined the relationship between peripheral blood and bronchoalveolar lavage (BAL) lymphocyte phenotypes and lung function in 19 patients with SLE, and evaluated their association with disease activity. Lung function assessment showed a mildly restrictive pattern with frequent impairment of transfer factor for carbon monoxide (T1,co) and diffusing capacity of the alveolocapillary membrane (Dm), of late-expiratory airflow rates and with a high prevalence of increased airway resistance. T1,co, Kco and Dm correlated inversely with the numbers of CD8+ cells and CD56+/CD16+/CD3- (NK) cells in BAL. Oxygen radical production, both by stimulated and unstimulated BAL cells and blood polymorphonuclear leucocytes (PMN) was significantly increased in SLE. In comparison with healthy controls, patients with SLE had a lower percentage of CD19+ B cells in the BAL versus an increased percentage of these cells in peripheral blood. HLA-DR expression on CD4+ and CD8+ lung lymphocytes was markedly increased in SLE. Current SLE disease activity was not associated with changes in BAL or peripheral blood lymphocyte phenotypes. Our data suggest that an ongoing cell-mediated immune response is present in the lungs in SLE, particularly involving activated CD8+ T cells and CD56+/CD16+/CD3- NK cells. It is associated with up-regulated local production of oxygen radicals and with impaired pulmonary diffusing capacity. This inflammatory process seems to be independent of general SLE disease activity. PMID:8403494

    Francisella tularensis causes the zoonosis tularemia in humans and is one of the most virulent bacterial pathogens. We utilized a global proteomic approach to characterize protein changes in bronchoalveolar lavage fluid from mice exposed to one of three organisms, F. tularensis ssp. novicida, an avirulent mutant of F. tularensis ssp. novicida (F.t. novicida-ΔmglA); and Pseudomonas aeruginosa. The composition of BALF proteins was altered following infection, including proteins involved in neutrophil activation, oxidative stress and inflammatory responses. Components of the innate immune response were induced including the acute phase response and the complement system, however the timing of their induction varied. Francisella tularensis ssp. novicida infected mice do not appear to have an effective innate immune response in the first hours of infection, however within 24 hours they show an upregulation of innate immune response proteins. This delayed response is in contrast to P. aeruginosa infected animals which show an early innate immune response. Likewise, F.t. novicida-ΔmglA infection initiates an early innate immune response, however this response is dimished by 24 hours. Finally, this study identifies several candidate biomarkers, including Chitinase 3-like-1 (CHI3L1 or YKL-40) and peroxiredoxin 1, that are associated with F. tularensis ssp. novicida but not P. aeruginosa infection.

In addition to a brief review of commonly assessed physiologic endpoints, attention is given in the first component of this report to the use of both nose breathing and mouth'' breathing rats in toxicity studies that involve measurements of ventilatory functional changes in response to test atmospheres. Additionally, the usefulness of maximum oxygen consumption, or VO[sub 2max], as a physiologic endpoint of toxicity that uses exercising rats after exposure to test atmospheres is described, along with an introduction to post-exposure exercise as an important behavioral activity that can markedly impact on the severity of acute lung injury caused by pneumoedematogenic materials. The second component of this report focuses on bronchoalveolar lavage and cytological and biochemical endpoints that can be assessed in investigations of the toxicities of test materials. As will be shown herein, some of the biochemical endpoints of toxicity, especially, can sensitively detect subtle injury to the lower respiratory tract that may escape detection by changes in some other conventional endpoints of toxicity, including lung gravimetric increases and histopathological alterations.
