Ascites Index - a novel technique to evaluate ascites in ovarian hyperstimulation syndrome: a concept-proof study.

OBJECTIVES: Controlled ovarian hyperstimulation is an important step in infertility treatment. In some cases, however, ovar-ian hyperstimulation syndrome (OHSS) can occur. In its severe forms, ascites is likely to develop, associated with dyspnea. The aim of this study was to explore the usefulness of Ascites Index (AsI), a new tool for quantitative determination of ascites in patients with OHSS, to obtain data for planning further trials. MATERIAL AND METHODS: Twelve patients with OHSS and ascites were included in the study. All patients were admitted to the hospital because of abdominal pain and dyspnea due to increasing ascites. Ultrasound measurements of ascites extent were performed in four external quadrants of the abdomen. Pockets of free fluid were measured. The obtained values were totaled, forming the Ascites Index (AsI), similarly to the amniotic fluid index. Because of dyspnea, paracentesis was performed in all cases. RESULTS: Median AsI at which patients reported dyspnea was 29.0 cm (range 21.6-38.6 cm). At AsI values less than 21.6 cm, no dyspnea was observed in any of the 12 studied patients. To avoid complications, 2000 mL of ascitic fluid was collected in each patient. After paracentesis, range of AsI decreased to 12.1-14.5 cm. CONCLUSIONS: The proposed AsI seems to be a promising tool for estimating and monitoring the ascites extent in OHSS. It can be estimated using basic ultrasound equipment. AsI requires further studies for standardization and transferability to other causes of ascites.

Extensive postpartum urinary retention successfully treated with clean intermittent catheterization.

We present a case of extensive urine retention after vaginal delivery. Postpartum urinary retention occurs in 0.7 to 0.9% of vaginal deliveries. In the literature, mediolateral episiotomy, epidural analgesia, perineal lacerations, macrosomic birth and prolonged 2nd stage of labor are suggested as risk factors for postpartum urine retention.

The role of levonorgestrel intrauterine systems in the treatment of symptomatic fibroids.

Uterine fibroids are considered to be the most frequently occurring tumours in females. The majority of fibroids do not require any treatment. When symptomatic, the major ailments include abnormal uterine bleeding, painful menstruation, pelvic pressure or pain, urinary problems, constipation, infertility, and recurrent pregnancy loss. Surgery remains a mainstay of symptomatic uterine fibroids therapy; however, minimally-invasive techniques and pharmacological management have become more available. The levonorgestrel intrauterine system (LNG-IUS) is a T-shaped device with a vertical stem containing a reservoir of levonorgestrel and is widely known for its contraception effect. Moreover, the non-contraceptive benefits of the LNG-IUS have been previously confirmed by numerous studies. LNG-IUS causes reduction of the duration and the amount of menstrual bleeding, with minimal side effects due to release of hormones at the targeted organ. Currently, results from systematic reviews show that LNG-IUS may be an effective and safe treatment for symptomatic uterine fibroids in premenopausal women. However, further studies are required to consolidate the usage of LNG-IUS in the treatment of symptomatic uterine fibroids.

Genital psoriasis: a hidden multidisciplinary problem - a review of literature.

Genital psoriasis is a variety of autoimmune dermatological disease - psoriasis with relapsing-remitting course, which can have an onset in all age groups. It is most often diagnosed at an advanced stage. Genital psoriasis is considered an embar-rassing condition and is often misjudged as a sexually transmitted disease or allergic reaction due to low social awareness of the disease. The manifestations of genital psoriasis may differ from typical genital dermatoses and with symptoms such as itch, erythroderma and vaginal discharge may mimic other diseases at an early stage. The diagnosis and treatment of genital psoriasis may be difficult and often requires a multidisciplinary approach. The aim of this article is to present the literature review of genital psoriasis concentrating on the clinical presentation, treatment and influence on the quality of patients' life and sexual activity disorders.

The influence of uterine artery embolisation on ovarian reserve, fertility, and pregnancy outcomes - a review of literature.

Uterine fibroids are considered to be the most frequent female benign tumours. Fibroids affect mainly women of reproductive age. The most frequently reported signs and symptoms of fibroids include disturbances of the menstrual cycle such as heavy bleeding and painful menstruation, pelvic masses associated with pelvic pain, urinary problems or constipation, as well as infertility and recurrent pregnancy loss. The mainstay of fibroid treatment is still surgery. However, many patients seek alternative treatment options for fibroids, to preserve their uterus and fertility. One of the most important alternative treatment options for fibroids is uterine artery embolisation (UAE). However, there are some concerns that UAE may negatively influence ovarian function and even result in premature menopause. Moreover, the use of UAE in patients with future reproductive plans is still controversial, due to the possible pregnancy complications. The purpose of this review is to summarise the current knowledge regarding the possible influence of UAE on fertility, pregnancy outcome, and ovarian reserve.

Elastography for predicting preterm delivery in patients with short cervical length at 18-22 weeks of gestation: a prospective observational study.

OBJECTIVES: The aim of the study was to estimate the potential value of elastographic evaluation of the internal cervical os at 18-22 weeks of pregnancy in patients with short cervical length for prediction of preterm delivery (PTD). MATERIAL AND METHODS: This prospective observational study included 109 patients with cervical length of ≤ 25 mm at 18-22 weeks scan. Stiffness of the internal cervical os was assessed by elastography. Elastographic assessment of the internal os was performed using a color map: red (soft), yellow (medium soft), blue (medium hard), and purple (hard). If two colors were visible in the region of the internal os, the softer option was noted. The following outcome measures were analyzed: percentage of PTDs in various categories of elastographic cervical assessment, sensitivity specificity negative predictive value (NPV), and positive predictive value (PPV) of elastography in predicting PTDs. Additionally ROC curves were constructed for elastography and cervical length for predicting PTDs. RESULTS: Forty-five cases of PTDs (< 37 weeks of pregnancy) were found in the studied population. The number of PTDs was significantly higher in the red group, than in the blue and purple groups. The sensitivity specificity NPV and PPV for the assessment of both, red and yellow internal os for predicting preterm delivery were 82.2%, 75.0%, 84.0% and 72.5% respectively The cut-off value for elastography suggested inclusion of both, red and yellow (warm) colors as predictors of PTD. CONCLUSIONS: Elastographic evaluation of the internal cervical os at 18-22 weeks of pregnancy in patients with short cervical length may be useful in predicting PTD.

Predicting the results of uterine artery embolization: correlation between initial intramural fibroid volume and percentage volume decrease.

INTRODUCTION AND OBJECTIVE: Uterine artery embolization (UAE) is a minimally invasive treatment option for symptomatic fibroids. Long-term follow-up studies have shown that at five-year follow-up after UAE, up to 30% of patients required a hysterectomy. Therefore, it seems of utmost importance to identify patients, who are unlikely to benefit from UAE. It has been postulated that the percentage volume reduction of fibroids may predict long-term UAE outcome. The results of available studies are equivocal, therefore it seemed of interest to investigate the correlation between the preinterventional intramural fibroid volume and imaging outcome of UAE in premenopausal patients. MATERIAL AND METHODS: Uterine artery embolization was performed in 65 premenopausal patients with symptomatic, intramural fibroids. Dominant fibroid volume was assessed using an integrated VOCAL (Virtual Organ Computer-aided AnaLysis) imaging program at baseline and 3 months after UAE. The percentage reduction of fibroid volume was calculated. The association between preinterventional fibroid volumes and percentage volume reductions was determined with the Spearman rank correlation test. RESULTS: Before UAE, the median dominant fibroid volume was 101 cm(3) (range 23.6-610). At three-month follow-up the median dominant leiomyoma volume decreased to 50.4 cm(3) (range 6.9-193.9). Median percentage reduction of fibroid volume three months after UAE was calculated at 50.1% (range 2.7-93.5). The Spearman correlation test between the preinterventional dominant fibroid volume and percentage volume reduction showed a statistically significant, positive correlation (R = 0.33; p = 0.006). CONCLUSIONS: The percentage volume reduction of intramural leiomyomas after UAE seems to be more pronounced in the case of larger tumors.

[Uterine artery embolization--clinical problems]. / Embolizacja tetnic macicznych--zagadnienia kliniczne.

The aim of the study was to present clinical issues concerning uterine artery embolization (UAE) in women with uterine fibromas. In order to ensure high clinical efficiency of UAE and prevent subsequent complications, it is necessary to carefully select patients eligible for the procedure. Patients with intramural fibromas, who do not plan to conceive, are the best candidates for the procedure. Fibroma necrosis, with following infection, and premature ovarian failure remain to be the most common complications after UAE. UAE may cause amenorrhea and increase FSH levels, what is typical for menopause. Thus, it may be responsible for problems with conception as well as optimal development of a pregnancy. It may also cause premature, iatrogenic menopause. This complication significantly more frequently occurs in women over the age of 45 as compared to younger patients. UAE is considered as an alternative therapeutic procedure, available to women who do not desire the surgery or wish to preserve the uterus. Patients subject to this procedure should be informed about the possible side effects.

Fragment-Based Discovery of 7-Azabenzimidazoles as Potent, Highly Selective, and Orally Active CDK4/6 Inhibitors.

Herein, we describe the discovery of potent and highly selective inhibitors of both CDK4 and CDK6 via structure-guided optimization of a fragment-based screening hit. CDK6 X-ray crystallography and pharmacokinetic data steered efforts in identifying compound 6, which showed >1000-fold selectivity for CDK4 over CDKs 1 and 2 in an enzymatic assay. Furthermore, 6 demonstrated in vivo inhibition of pRb-phosphorylation and oral efficacy in a Jeko-1 mouse xenograft model.

Quinic acid derivatives as sialyl Lewis(x)-mimicking selectin inhibitors: design, synthesis, and crystal structure in complex with E-selectin.

A search for noncarbohydrate sLe(x) mimics led to the development of quinic acid derivatives as selectin inhibitors. At Wyeth we solved the first cocrystal structure of a small molecule, quinic acid, with E-selectin. In the cocomplex two hydroxyls of quinic acid mimic the calcium-bound fucose of the tetrasaccharide sLe(x). The X-ray structure, together with structure based computational methods, was used to design quinic acid based libraries that were synthesized and evaluated for their ability to block the interaction of sLex with P-selectin. A large number of analogues were prepared using solution-phase parallel synthesis. Selected compounds showed decrease in leukocyte rolling in the IVM mouse model. Compound 2 inhibited neutrophil influx in the murine TIP model and demonstrated good plasma exposure.

[The role of endocrine factors in the pathogenesis of spontaneous abortion after IVF-ET]. / Rola przyczyn endokrynnych w etiopatogenezie poronienienia samoistnego po IVF-ET.

There is large body of evidence to show that the risk of early pregnancy loss is higher after IVF-ET than after natural conception. Several hypotheses have been proposed to explain this phenomenon. One of the possible etiopathogetic factors is the patient's age which is significantly higher in women undergoing IVF than in the general population of naturally conceiving women. Immunologic factors have also been suggested. It seems that procedures like ICSI do not increase the risk of spontaneous abortion (SAB) after IVF-ET. Moreover, the proportion of products of conception with chromosomal aberration in cases of SAB following ICSI procedure is not elevated. Many authors point to the problem of iatrogenic luteal defect after IVF-ET. The use of luteal support after IVF-ET is widely recommended. Interestingly, firm evidence is lacking regarding the efficacy of progestagen or hCG supplementation on the risk of SAB after IVF-ET. However the issue of the effectiveness of progesterone support in decreasing the risk of SAB after ART procedures is far from being conclusively resolved--it deserves well planned, randomized studied to be performed.

Serum total cholesterol, triglycerides and high density lipoproteins (HDL) levels in rabbit during the course of experimental diabetes.

The study was conducted on 56 rabbits, of White New Zealand breed, male gender. The average weight of the rabbits was 3 kg. The diabetes was evoked by intravenous injection of 10% alloxan, using the single dose of 100 mg/kg. On the 7th day after administration of alloxan, serum glucose levels were determined. The serum glucose level higher than 11.1 mmol/l was considered an indicator of the presence of diabetes. All the animals included in the study were divided into five groups: the control, 21-day diabetes, 42-day diabetes, 90-day diabetes and 180-day diabetes. Serum total cholesterol, triglycerides and high density lipoproteins levels were determined with enzymatic methods. Our studies revealed a significant increase in cholesterol and triglycerides levels. That mechanism might be responsible for faster development of atheromatosis during the course of diabetes mellitus.
