Published: February 2014

AbstractAimsHemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome, in its complete form, is associated with increased risk of maternal mortality and increased rate of serious obstetric complications, such as acute renal failure, hepatic failure, abruptio placentae, pulmonary edema, sepsis, hemorrhage and disseminated intravascular coagulopathy. To compare maternal and perinatal outcomes, we investigated the subsequent pregnancy outcomes and long‐term complications of women with partial HELLP (pHELLP) and complete HELLP (cHELLP) syndromes.Material and MethodsIn this retrospective study, patients complicated with HELLP between the years 2002 and 2007 were analyzed. cHELLP syndrome was defined by the presence of all of the three laboratory criteria according to the Tennessee Classification System. pHELLP syndrome was defined by the presence of one or two features of HELLP, but not the complete form.ResultsSixty‐four patients had cHELLP syndrome and 67 had pHELLP syndrome. Maternal complications and neonatal outcomes of the indexed pregnancies were similar. The rate of blood product transfusion was significantly higher in the cHELLP group (P < 0.0001). Twenty‐eight patients within the cHELLP group and 26 within the pHELLP group had subsequent pregnancies with a mean interpregnancy interval of 2.9 ± 1.5 years and 2.4 ± 1.1 years, respectively. Elective termination of pregnancy (dilatation and curettage) was more frequent in the cHELLP group. Pre‐eclampsia recurrence was higher in the pHELLP group than in the cHELLP group (7.1% vs 34.6%).ConclusionsPartial and complete HELLP syndrome are not distinct groups based on neonatal, long‐term and subsequent pregnancy outcomes. They probably represent a continuum in the natural evolution of the same disease.

AbstractAimThe aim of this prospective randomized study was to evaluate the efficacy of estrogen in preventing intrauterine adhesions following hysteroscopic septal resection and to investigate its effect on reproductive outcome.Materials and MethodsAfter hysteroscopic septal resection, 90 women received either estrogen or placebo (n = 45 per group) for 30 days. A second‐look hysteroscopy was performed after 2 months. All pregnancies occurring during the study period were recorded.ResultsAdhesions developed in three of 43 (6.9%) patients in the control group compared to none in the estrogen group. This difference was not statistically significant (P = 0.24). Regarding reproductive outcome, the differences between the two groups were also not significant.ConclusionEstrogen treatment was not found to prevent intrauterine adhesions or improve reproductive outcome after hysteroscopic septal resection.

AbstractPseudo‐Meigs' syndrome secondary to uterine leiomyoma is a rare entity. A 50‐year‐old Japanese woman presented with a 3‐month history of shortness of breath. Chest X‐ray and magnetic resonance imaging revealed massive right pleural effusion, ascites and a large subserosal uterine myoma. She underwent a total abdominal hysterectomy with bilateral salpingo‐oophorectomy. The pathology was consistent with a benign leiomyoma. The ascites and pleural effusion rapidly disappeared postoperatively. The serum interleukin‐6 level was 3.9 pg/mL before surgery and declined to 1.6 pg/mL postoperatively. Previous published work has demonstrated that vascular endothelial growth factor and interleukin‐6 may play a role in the pathogenesis of Meigs' syndrome and that vascular endothelial growth factor may contribute to the development of pseudo‐Meigs' syndrome due to metastatic ovarian cancer. This is the first English‐language study showing the possibility that interleukin‐6 is relevant to the pathogenesis of pseudo‐Meigs' syndrome caused by degenerating uterine leiomyoma.

AbstractWe report a case of renal vein thrombosis diagnosed at 27 weeks of gestation in a dichorionic twin pregnancy. The left kidney of one fetus was hyperechoic and enlarged with echoic streaks following the direction of interlobular veins and the loss of corticomedullary differentiation. In the following weeks, left kidney became smaller and echoic, and Doppler examination showed no flow in both artery and vein. The right kidney had totally normal appearance in the beginning, but it became enlarged and hyperechoic, and progressed into a small echoic kidney with no flow in artery and vein. In the postnatal ultrasound examination, both kidneys appeared hyperechoic with no vascularization in the hilum region. There was thrombosis in arteries and veins of both kidneys, as well as in the inferior vena cava. The investigation for thrombophilia resulted with the combined presence of heterozygote mutation in factor V Leiden and prothrombin 20210 genes.

Published: February 2014

AbstractHydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic‐cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27‐year‐old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin‐walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

Published: February 2014

AbstractAimTo compare levator defect, loss of tenting, change in biometric measurements of the levator ani and genital hiatus according to the mode of delivery, length of the labor, Bishop score, birthweight and head circumference immediately after delivery.MethodsOne hundred and seventy‐one primiparous women who delivered either by vaginal delivery or cesarean were prospectively evaluated. Two 3‐D volumes (one at rest, one on Valsalva maneuver) were recorded in the supine position after voiding, and levator biometry, levator defect and loss of tenting were determined on the axial plane.ResultsOf 171 nulliparous women, 84 had vaginal delivery and 87 had cesarean delivery. All hiatal dimensions on resting and maximal Valsalva were found to be higher in the vaginal delivery group. Levator defect rate was found to be significantly higher in the vaginal delivery group (P < 0.0001). We found a positive correlation with head circumference, fetal weight and first stage labor length in women who delivered vaginally. In the cesarean delivery group, mean fetal head circumference, fetal weight, length of first stage of labor and Bishop score were higher in women with levator ani defect. Loss of tenting rate was significantly higher in vaginal delivery women (P = 0.03).ConclusionLabor itself, and factors such as fetal head circumference and fetal weight that cause prolongation of labor, can induce levator ani muscle defect or microtrauma which in turn can cause morphological alterations of the levator hiatus.

AbstractAimWhether prevalence rate of pregnancy‐induced hypertension (PIH), including gestational hypertension and pre‐eclampsia, is lower for summer delivery than for winter delivery remains to be studied in Japanese women.MethodsThe prevalence rate of PIH was retrospectively determined according to month of year at delivery and at conception in 301 510 Japanese women who gave birth to singleton infants on or after gestational week 22 between 2005 and 2009.ResultsThe overall prevalence of PIH was 4.6% (13 848/301 510). The prevalence rate of PIH, ranging 3.6–4.6% for women with deliveries in July–August was consistently lowest during the 5‐year study period. The mean ± standard deviation prevalence rate of 4.2 ± 0.3% for delivery in July–August was significantly lower than those for any other month (January–February, 4.7 ± 0.4%; March–April, 4.9 ± 0.4%; May–June, 4.6 ± 0.2%; September–October, 4.6 ± 0.1%; and November–December, 4.6 ± 0.2%). The prevalence rate of PIH was highest (4.9%) for women with conception in March and April and lowest (2.9%) for those with conception in November and December.ConclusionThe prevalence rate of PIH was higher for delivery in winter and early spring and lowest for summer delivery among Japanese women.

AbstractAimTo define the optimal gestational weight gain (GWG) for the multiethnic Singaporean population.MethodsData from 1529 live singleton deliveries was analyzed. A multinomial logistic regression analysis, with GWG as the predictor, was conducted to determine the lowest aggregated risk of a composite perinatal outcome, stratified by Asia‐specific body mass index (BMI) categories. The composite perinatal outcome, based on a combination of delivery type (cesarean section [CS], vaginal delivery [VD]) and size for gestational age (small [SGA], appropriate [AGA], large [LGA]), had six categories: (i) VD with LGA; (ii) VD with SGA; (iii) CS with AGA; (iv) CS with SGA; (v) CS with LGA; (vi) and VD with AGA. The last was considered as the ‘normal’ reference category. In each BMI category, the GWG value corresponding to the lowest aggregated risk was defined as the optimal GWG, and the GWG values at which the aggregated risk did not exceed a 5% increase from the lowest aggregated risk were defined as the margins of the optimal GWG range.ResultsThe optimal GWG by pre‐pregnancy BMI category, was 19.5 kg (range, 12.9 to 23.9) for underweight, 13.7 kg (7.7 to 18.8) for normal weight, 7.9 kg (2.6 to 14.0) for overweight and 1.8 kg (−5.0 to 7.0) for obese.ConclusionThe results of this study, the first to determine optimal GWG in the multiethnic Singaporean population, concur with the Institute of Medicine (IOM) guidelines in that GWG among Asian women who are heavier prior to pregnancy, especially those who are obese, should be lower. However, the optimal GWG for underweight and obese women was outside the IOM recommended range.
Men's Use and Perceptions of Commercial Lubricants: Prevalence and Characteristics in a Nationally Representative Sample of American Adults

Published: February 2014

Abstract

Introduction
Most research on men's use of commercial lubricants during sexual activities is in the context of condom use and often specifically among men who have sex with men. Less is known about men's use of lubricants associated with a broader range of sexual experiences.

Aims
The aims of this study are to document the prevalence of commercial lubricant use among adult U.S. men (age 18+), to document men's use of lubricants across solo and partnered sexual behaviors, and to assess men's perceptions of the contributions lubricants have to the sexual experience.

Methods
Data are from the 2012 National Survey of Sexual Health and Behavior, which involved the administration of an online questionnaire to a nationally representative probability sample of U.S. adults ages 18 and older.

Main Outcome Measures
Sociodemographic characteristics, recent and lifetime commercial lubricant use, lubricant use during specific sexual behaviors, frequency of lubricant use, and reasons for lubricant use.

Results
Most men in the United States (70%, N = 1,014) reported having used a commercial lubricant, with men older than 24 and those in a relationship more likely to report lubricant use. About one in four men had used a lubricant in the past 30 days. Intercourse was the most common behavior during which men used lubricant, though solo masturbation and partnered sexual play were also frequently linked to lubricant use. The most common reasons for lubricant use included “to make sex more comfortable,” “for fun,” “curiosity,” and “my partner wanted to.”

Conclusions
Most American men have used a lubricant; lubricant use is common across all age groups, and some of the most common reasons why men report using lubricants have to do with sexual enhancement, comfort, and pleasure. Clinicians may find these data helpful to their efforts to educate patients about lubricant use, comfort during sex, and sexual enhancement.

SummaryGenetic resistance to specific infections is well recognized. In hepatitis C virus (HCV) infection, genetic polymorphisms in IL‐28B and the killer cell immunoglobulin‐like receptors (KIR) and their HLA class I ligands have been shown to affect clearance of the virus following infection. There are limited data regarding resistance to established HCV infection. Reliable quantification of repeated exposure in high‐risk populations, such as injecting drug users (IDU), is a key limitation of previous studies of resistance. Behavioural data and DNA from IDU (n = 210) in the Hepatitis C Incidence and Transmission Study in prisons (HITS‐p) cohort were genotyped for polymorphisms in: IL‐28B, peptidyl‐prolyl isomerase A (PPIA), HLA‐C and KIR2. To quantify risk, a composite risk index based on factors predictive of incident HCV infection was derived. Logistic regression analysis revealed the risk index was strongly associated with incident HCV infection (P < 0.0001). The upper tertile of the uninfected individuals had risk indices comparable to the incident cases, but remained uninfected. There were no significant differences in the frequencies of IL‐28B or PPIA polymorphisms between these exposed‐uninfected cases, or in the frequencies of KIR2‐DL3, HLA‐C1, or their combination. A framework for the investigation of genetic determinants of resistance to HCV infection has been developed. Several candidate gene associations were investigated and excluded. Further investigation of genetic determinants of resistance to HCV infection is warranted.

Published: February 2014

AbstractJellyfish are often the most prominent components of plankton, with severe consequences for fisheries and tourism. However, in tropical regions, there is much uncertainty about these consequences due to the lack of basic data. Our objective was to improve the knowledge about jellyfish in the Western Atlantic, with an emphasis on understanding diversity, abundance, and distribution patterns. Samples were collected at 34 stations in 1995 using a 300‐μm‐mesh Bongo net. The 21 species identified belonged to Hydromedusae (11), Siphonophora (nine), and Scyphomedusae (one). The overall mean density was low (5.2 ± 5.3 ind. m−3). Total Hydromedusae biomass was 130.86 mg C m−3, and total Siphonophora biomass was 19.04 mg C m−3. Chelophyes appendiculata (Eschscholtz, 1829) was the most frequent species captured in the oceanic samples, and Aglaura hemistoma (Péron & Lesueur, 1810) was the most common in the neritic region. The latter species is sometimes characterized as a bloom associated with the most polluted and eutrophic river plumes. The main role of jellyfish species in the area is as a higher‐order carnivore. A cross‐shelf significant difference (P < 0.05) was registered, with higher species numbers in oceanic regions and higher densities and biomass in neritic regions.
Output‐Only Identification and Model Updating by Dynamic Testing in Unfavorable Conditions of a Seismically Damaged Building

Published: February 2014

AbstractKnowledge of the dynamic behavior of complex buildings subjected to near‐fault earthquakes may be enriched by valuable information obtained through rapid onsite dynamic testing to aid in the design of appropriate retrofitting interventions. Through a case study, the article demonstrates the enhancement in comprehension of the structural behavior obtained by means of a 2‐day testing campaign conducted on a complex building of the Engineering Faculty, Edifice A, which was heavily damaged in the 2009 L'Aquila earthquake. The onsite testing was carried out with a network of 13 accelerometers opportunely located to identify the dynamic characteristics of the structure by means of ambient noise‐induced vibration. Enhanced Frequency Domain Decomposition (EFDD) and Stochastic Subspace Identification (SSI) output‐only procedures were both used to identify the main modal parameters of two substructures of the building. The modal characteristics were used to update a finite element model representing small amplitude vibrations of the damaged structures. The direct comparison of the identified modal features with finite element models, in which damaged member locations are determined by onsite visual observations, has permitted identification of a model representative of the structural behavior of the building in the immediate postearthquake conditions.

ObjectiveTo evaluate whether preoperative range of motion is a key determinant of postoperative range of motion in Asian patients undergoing conventional total knee arthroplasty.MethodsA retrospective review of 302 patients who underwent primary total knee arthroplasty performed by a single surgeon was conducted. Patients who had a fixed flexion deformity of ≥15° were excluded. Postoperative range of motion (ROM) was measured prospectively. Patients were stratified into two groups: preoperative ROM < 110° and preoperative ROM ≥ 110°. Postoperative ROM and mean change in ROM at 6 months and 2 years of follow‐up were then compared using Student's t‐test.ResultsGroup of ROM < 110° had a poorer postoperative range of motion at both 6‐months and 2‐years of follow‐up than Group of ROM ≥ 110° (P < 0.001). Postoperatively, Group of ROM < 110° had gained range of motion whereas Group of ROM ≥ 110° had lost range of motion (P < 0.001).ConclusionsSimilar to the Western population, preoperative range of motion is a key determinant of postoperative range of motion in Asian patients. This should be taken into consideration by surgeons during preoperative planning and in managing patients’ expectations.

ObjectiveTo assess the difference between drainage and non‐drainage after total hip arthroplasty (THA) in Chinese subjects by evaluating post‐operative complications and joint function.MethodsOne hundred and sixty‐eight patients undergoing THA were randomly allocated into drainage (83 patients) and non‐drainage groups (85 patients). All surgeries were performed by one surgical team using the same pre‐, intra‐, and postoperative techniques. Measured items included: hemoglobin (Hb), superficial and deep wound infection, volume of blood transfusion, wound hematoma thickness, range of motion (ROM) of the hip, wound healing time, ecchymosis and tension vesicles around the wound.ResultsEarly after THA, the Hb decreased significantly in the drainage group. There was no significant difference between non‐drainage and drainage groups in need for or volume of blood transfusions (9.6% vs 8.2%, P = 0.100; 3.8 units vs 2.9 units, P = 0.089, respectively). In the non‐drainage group, the incidence of superficial infection, ecchymosis and tension vesicles was significantly higher than in the drainage group (10.6% vs 2.4%, P = 0.031; 12.9% vs 3.6%, P = 0.026; 16.5% vs 4.8%, P = 0.013, respectively). In addition, the non‐drainage group had a greater volume of hematomas (P = 0.000). Patients in the non‐drainage group had smaller ROMs early after surgery but the final ROMs did not differ significantly between groups. No deep infection occurred in either group.ConclusionNon‐drainage may reduce postoperative blood loss but has no benefits regarding blood transfusion or deep infection. It may cause more post‐operative complications because of restriction of early postoperative exercise by pain and swelling. Therefore we suggest routine use of drainage after THA.
