    We present a case of vaginal ectopic ureter with ipsilateral partial duplication of the upper ureter (Y-type ureter), ipsilateral hypoplastic pelvic kidney and bicornuate uterus in a 20-year-old woman who presented with mild urinary incontinence since infancy. Ultrasonography, computed tomography and intravenous pyelography examination showed a left kidney with no evidence of a right kidney. Cystourethroscopy showed absence of the right hemitrigone. Magnetic resonance (MR) urography demonstrated the presence of a bicornuate uterus, an ectopic dysplastic right kidney in the pelvic cavity, and a right ureter that terminates in the vaginae fornix. The patient underwent right nephroureterectomy and urinary continence was restored completely. Although congenital malformations of the urinary tract are frequently associated with genital tract abnormalities, to best our knowledge, this is the first report of the coexistence of all of these anomalies in an individual. Our report also highlights the importance of MR urography in the diagnosis of such rare and complex anomalies. PMID:23712785

    A girl with continuous urinary incontinence was successfully treated by angiographic embolization of a hypoplastic pelvic kidney with a single unilateral vaginal ectopic opening of the ureter. For this intervention, CT angiography was useful for detecting the corresponding renal artery of the hypoplastic kidney.

    Summary Background If a kidney does not ascend as it should in normal fetal development, it remains in the pelvic area and is called a pelvic kidney. Often a person with a pelvic kidney will go through his/her whole life unaware of this condition, unless it is discovered during neonatal kidney ultrasound screening or if complications arise later in life due to this or a completely different reason and the condition is noted during investigations. Generally, this is not a harmful condition but it can lead to complications like in our case. With appropriate testing and treatment, if needed, an ectopic kidney should cause no serious long-term health complications and all that may be required for the patient is reassurance with advice to follow up at regular intervals. Case Report A 28-year-old male presented with recurrent pain in his lower left abdomen for one month and an episode of hematuria 3 days earlier accompanied by an attack of acute pain lasting for 3–4 hours. He gave a history of passing 2 small (about 5 mm each) calculi in his urine after the occurrence of hematuria, following which pain decreased in intensity. No history of fever was present. Conclusions Although a simple ectopic kidney seldom causes symptoms, the association of malrotation of the renal pelvis with calculus increases the risk of hematuria and/or hydronephrosis, presenting with colicky pain as in the present case. The clinician should be aware of these in such a case. If asymptomatic, no treatment is required. However, the patient should be advised to have follow-up ultrasounds at regular intervals to detect complications like calculus, hydronephrosis, etc. With appropriate testing and treatment, if required, an ectopic kidney should not cause serious long-term health complications.

    Mesonephric remnants have been rarely reported in the genitourinary system and sometimes impose a diagnostic challenge both clinically and pathologically. We reported a case of mesonephric remnant hyperplasia with mixed acinar/tubular and epididymis/vas deferens-like morphologies occurring in the renal parenchyma of a unilateral hypoplastic kidney, which has not been previously described.

    We report the case of a gentleman referred with apparent worsening function in a hydronephrotic left-sided pelvic kidney. Imaging with Tc-99m-Mercaptoacetyltriglycine (MAG 3) in 1999, showed that the left kidney contributed 46% of renal function with no evidence of obstruction. Three years later, repeat scanning showed ectopic kidney function had decreased to 20% and with worsening pain, nephrectomy had been suggested. Review of the second MAG 3 scan revealed that only posterior images had been obtained. With pelvic kidneys, the pelvis forms a barrier between the radioactively labelled tracer and the gamma camera, thus, reducing the amount of radiation detected and underestimating function. A subsequent Dimercaptosuccinic acid scan (DMSA) was carried out with posterior and anterior images, the latter showing split renal function was identical to that seen on the initial scan. In patients with pelvic kidneys, anterior views must be obtained during radionuclide scanning if unnecessary nephrectomy is to be avoided. PMID:15875644

    Anomalous kidneys are mostly asymptomatic and are often found incidentally during physical or radiological investigations for urological or other medical complaints. The associated genital anomalies ranges from 15% to 45%. Females are associated with bicornuate or unicornuate uterus, rudimentary or absent uterus while males have undescended testes, duplication of the urethra, and hypospadias. A 21 year old married female presented with on and off lower abdomen pain for the past one year with history of primary amenorrhea. On examination an ill defined tender lump palpated in the lower abdomen. USG showed left ectopic pelvic kidney with gross hydronephrosis. The computed tomography confirmed hydronephrotic left ectopic pelvic kidney in front of the sacrum with anteriorly directed renal pelvis with ureter located posteriorly. There was delayed excretion from the ectopic kidney but right kidney was in normal position and function. The diethylene triamine pentaacetic acid (DTPA) scan showed 33% function of the ectopic kidney. On diagnostic laparoscopy, the uterus was small hypoplastic with bilateral ovaries appearing normal. The patient was taken for open pyeloplasty where the ureter was transected below PUJ but for a dependent drainage, the middle calyx as was the most dependent calyx as seen on the CT-scan. So a middle calyx ureterocalicostomy was performed calyx with excellent outcome. The ectopic kidney always remains a challenge because of complex neurovascular anatomy, presence of viscera and associated UPJO, but for a dependent drainage, middle calyx ureterocalicostomy is a feasible option with excellent outcome as was in our case.

    Abstract Hepatocyte nuclear factor 1 beta (HNF1B) plays an important role in embryonic development, namely in the kidney, pancreas, liver, genital tract, and gut. Heterozygous germline mutations of HNF1B are associated with the renal cysts and diabetes syndrome (RCAD). Affected individuals may present a variety of renal developmental abnormalities and/or maturity-onset diabetes of the young (MODY). A Portuguese 19-month-old male infant was evaluated due to hypoplastic glomerulocystic kidney disease and renal dysfunction diagnosed in the neonatal period that progressed to stage 5 chronic renal disease during the first year of life. His mother was diagnosed with a solitary hypoplastic microcystic left kidney at age 20, with stage 2 chronic renal disease established at age 35, and presented bicornuate uterus, pancreatic atrophy, and gestational diabetes. DNA sequence analysis of HNF1B revealed a novel germline frameshift insertion (c.110_111insC or c.110dupC) in both the child and the mother. A review of the literature revealed a total of 106 different HNF1B mutations, in 236 mutation-positive families, comprising gross deletions (34%), missense mutations (31%), frameshift deletions or insertions (15%), nonsense mutations (11%), and splice-site mutations (8%). The study of this family with an unusual presentation of hypoplastic glomerulocystic kidney disease with neonatal renal dysfunction identified a previously unreported mutation of the HNF1B gene, thereby expanding the spectrum of known mutations associated with renal developmental disorders.

    Our goal is to describe our experience in the difficulties encountered during radical cystectomy for muscle invasive bladder cancer in patients with contemporary pelvic kidney. Two patients with muscle invasive bladder cancer and contemporary pelvic kidney were subjected to radical cystectomy and extended lymphadenectomy with conversion to an ileal pouch. In both cases, lymphadenectomy was the first step after entering the true pelvis. In order to proceed to the cystoprostatectomy, careful dissection of the ectopic renal vessels and proper mobilization of the kidney were performed. In both cases, an ileal pouch was our choice. The pelvic kidney is the most common sight of renal ectopia. The etiology is the aborted ascent of the fetal kidney from its initial position in the pelvis. This is the first case series describing radical cystectomy for muscle invasive urothelial carcinoma of the bladder in patients with a pelvic kidney. PMID:24307907

    Variations of structure and position of the kidney along with variations of renal vessels are most frequently reported. Rotational variations form a rare entity that are not cited in most embryology textbooks. During an educational cadaveric dissection of a 42-year-old male, a complex picture of bilateral anatomical variants was encountered. Malrotation of both kidneys and a left lobulated ectopic kidney along with open hilum was observed. The left kidney showed a pelvic position in front of sacral promontory with three renal arteries retaining its embryological aortoiliac branches and two renal veins draining into right common iliac vein. These variations have an embryological base. Pelvic kidney with rotational variation though comparatively rare assumes great importance in view of present-day surgical procedures like laparoscopic radical nephrectomy, percutaneous nephrectomy, and renal transplantation.

    Abdominal aortic aneurysm (AAA) is rarely associated witha congenital pelvic kidney. To date only 11 cases have been reported in the literature in which a solitary pelvic' kidney was associated in only 1 patient. Repair of thesaneurysm is technically demanding because the abnormal origin of the renal arteries presents the problem of renal ischemia duringaortic cross-clamping. We report a case of a 77-year-old man who was found to have an AAA associated with a congenital solitary pelvic kidney. An abdominal aortography dearly showed 2 aberrant renal arteries, one of which originated from the aortic wall just above the aortic bifurcation and the other from the left common iliac artery. At surgery, we found other associated anomalies including malrotation of the gut and a left undescended testis. The surgical procedure consisted of an aneurysmorrhaphy followed by a tube graft replacement with therenal arteries being left intact to the distal aortic wall or below. Renal preservation during aortic cross-clamping was achieved by direct perfusion of the upper renal artery with cold lactated Ringer's solution together with topical cooling with ice slush. The patient's postoperative course was uneventful. Urinary output was satisfactory and serum creatinine level remained unchanged throughout his hospital stay. The renal preservation method used in this case was simple and effective. PMID:15736573

    Introduction: The treatment of renal lithiasis has undergone a sea change with the advent of extracorporeal shock wave lithotripsy (ESWL) and endourological procedures such as percutaneous nephrolithotomy (PCNL), ureterorenoscopy and retrograde intrarenal surgery (RIRS). The presence of anatomical anomalies, such as ectopic pelvic kidney, imposes limitations to such therapeutic procedures. This study is aimed to find a simple and effective way to treat the stones in ectopic kidney. Materials and Methods: From 2010 to 2014, nine patients underwent laparoscopic-assisted mini PCNL with Laser dusting for calculi in ectopic pelvic kidneys at our hospital. Retrograde pyelography was done to locate the kidney. Laparoscopy was performed and after mobilizing the bowel and peritoneum, the puncture was made in the kidney and using rigid mini nephroscope, and stones were dusted with Laser. Results: The median interquartile range (IQR) stone size was 18 (6.5) mm. Median (IQR) duration of the procedure was 90 (40) min. The median (IQR) duration of postoperative hospital stay was 4 (2) days. The stone clearance in our series was 88.9%, with only one patient having a residual stone. No intra- or post-operative complications were encountered. Conclusion: Laparoscopy-assisted mini PCNL with Laser dusting offers advantages in ectopic pelvic kidneys in achieving good stone clearance, especially in patients with a large stone burden or failed ESWL or RIRS.

    To demonstrate the safety and efficacy of combine laparoscopy and flexible ureteroscopy to treat ectopic pelvic kidneys with ureteropelvic junction obstruction (UPJO) and stones. 16 patients of ectopic pelvic kidneys with ureteropelvic junction obstruction and stones were treated with laparoscopy and flexible ureteroscopy (FURS). The operative time, required dose of tramadol, visual analog pain scale (VAPS), postoperative day, stone-free rates (SFRs), perioperative complications, and serum creatinine were evaluated. The SFRs were evaluated with noncontrasted renal computed tomography (CT). Intravenous pyelography (IVP) and CT scan were used to evaluate the UPJO. Stone-free status was defined as absence of stone fragments in kidney or the size of that is less than 3 mm. Operation time from 118 to 225 min, average time (171 ± 28) min; lithotomy time from 16 to 45 min, average time (32 ± 6) min. Average tramadol required at the first day postoperation was (118 ± 49.6) mg; at the second day was (78 ± 24.8) mg. VAPS score at 24 h (5.0 ± 0.7), VAPS score at 48 h (2.5 ± 0.8). Postoperative day (3.9 ± 0.6) days. Stone-free rate was 100%. Average serum creatinine was (88.7 ± 24.3) mol/L before surgery and (92.8 ± 21.6) mol/L after surgery. No major complication. No stone and obstruction recurrence in the follow-up of average 29.3 months. Combined FUR and LC is a good option for patient of ectopic pelvic kidney with renal stone and UPJO. From our initial experience, the SFRs and the effect of pyeloplasty are satisfactory and without major complication, the operative time is acceptable. PMID:25666341

    A general formulation of the theory of hypoplasticity is given, under the assumption that Cauchy stress is the only state variable. Such a formulation allows to discuss the relation between the so-called out-of-axis and in-axis moduli. It is proved that, in general, the out-of-axis moduli are independent from the in-axis moduli, which allows the former to be calibrated making use of experimental shear band data, as it is done in CLoE-hypoplasticity. The implicit assumptions made in K-hypoplasticity are detailed for two particular models of this family. Copyright

    Objective The aim of this study was to evaluate the difference in measured glomerular filtration rate (GFR) of an ectopic pelvic kidney between anterior and posterior image processing using Gates’ method of renal dynamic imaging. Methods A total of 10 patients were studied retrospectively, with a single ectopic kidney in the pelvic cavity and a contralateral kidney at its normal anatomical position confirmed by ultrasound, computed tomography, renal dynamic imaging, etc. All images of ectopic kidneys were processed, and GFRs were measured using anterior and posterior Gates’ method of renal dynamic imaging, respectively. The contralateral normal kidney was only processed on posterior imaging. The total GFRant of one patient, which was equal to the sum of the GFR of a normal kidney on posterior imaging and the GFR of an ectopic kidney on anterior imaging, was compared with the total GFRpost of two kidneys on posterior imaging, with the GFRtwo-sample from the two-sample method, and with the estimated GFR in the Chronic Kidney Disease Epidemiology Collaboration equation. All correlation analyses were carried out between GFRs obtained from three methods, and all patients were followed up. For statistical analysis, nonparametric rank tests were used, Bland-Altman graphs were plotted. Results The mean GFR of the ectopic kidney on anterior imaging was 27.48±12.24 ml/min/1.73 m2. It was higher than the GFR (10.71±4.74 ml/min/1.73 m2) on posterior imaging (t=−2.803, P<0.05). There were statistical differences between the total GFRant and the total GFRtwo-sample (Z=−2.295, P<0.05), between the total GFRant and the total GFRpost (Z=2.599, P<0.01), between the total GFRtwo-sample and the total GFRpost (Z=−2.191, P<0.05), and between the total GFRant and the estimated glomerular filtration rate (Z=−2.803, P<0.01). The bias of the total GFRant was different from that of the total GFRpost (Z=−2.191, P<0.05). There were no differences in the precision and accuracy within 30% of the total GFRant and that of the total GFRpost (precision: F=0.351, P>0.05), but there were statistical differences in the accuracy within 10% of the total GFRant and that of the total GFRpost (P<0.05). Conclusion The GFR measured using Gates’ method of anterior image processing was more accurate than the GFR obtained on posterior image processing in reflecting the function of an ectopic pelvic kidney in renal dynamic imaging.

    Agenesis of the inferior vena cava (IVC) is a rare anomaly which can be identified as incidental finding or can be associated with iliofemoral vein thrombosis. IVC agenesis has a known association with renal anomalies which are mainly confined to the right kidney. We describe a case of a 14-year-old male who presented with left leg swelling and pain. Ultrasonography confirmed the presence of left leg deep vein thrombosis (DVT). No underlying hematologic risk factors were identified. A CT scan was obtained which demonstrated absent infrarenal IVC and extensive thrombosis in the left deep venous system and development of collateral venous flow into the azygous/hemiazygous system, with extension of thrombus into paraspinal collaterals. An additional finding in the patient was an atrophic left kidney and stenosis of an accessory left renal artery. Agenesis of the IVC should be considered in a young patient presenting with lower extremity DVT, especially in patients with no risk factors for thrombosis. As agenesis of the IVC cannot be corrected, one should be aware that there is a lifelong risk of lower extremity DVT. PMID:25685585

    Hypoplastic left heart syndrome (HLHS) is one of the last remaining problems in pediatric cardiac surgery, which necessitates a search for new solutions and continues to be a challenge for cardiologists and cardiac surgeons. The identification of HLHS in utero is extremely helpful for prompt, appropriate preoperative management. In addition, infants with prenatal diagnosis had an improvement operative mortality on Norwood operation compared to infants diagnosed postnatally. Outcome following Norwood procedure has improved significantly secondary to modifications in the surgical technique for protection of multiorgans, improved perioperative care, and improved anesthetic management. In particular right ventricular (RV)-pulmonary artery (PA) shunt using non-valved polytetrafluoroethylene (PTFE) graft was applied as a first stage palliation of HLHS to prevent hemodynamic instability associated with a classic Norwood procedure. In the modified Norwood (RV-PA shunt), higher diastolic blood pressures and lower Qp/Qs ratios that are associated with a more stable and efficient systemic circulation. In fact, patients who received a RV-PA shunt, rarely received ventilatory manipulations. PMID:15362550

    2010-05-01

    This paper provides an extension to Cosserat mechanics of a recently proposed version of hypoplasticity [1], and this extension is achieved economically by means of a novel complex-variable formulation of Cosserat theory. The present work represents a compact synthesis and theoretical framework for both non-polar and polar hypoplasticity, and it encompasses various special cases considered in the literature, as discussed in the recent monograph by Tejchman [2]. The current approach offers a perspective on granular dilatancy, elastoplastic yield, and energy dissipation which differs from the standard hypoplasticity and which serves to establish a connection to classical incremental plasticity. In contrast to the classical theory, the present approach, based entirely on the concept of pseudo-linear forms, admits but does require elastoplastic potentials to describe plastic flow. When such potentials are assumed, it is shown that they can be related to the plastic moduli of the present formulation. It is also shown that hypoplasticity allows for a distinction between active and passive internal variables, with the latter serving to define parameters. Finally, the known forms for linear isotropic Cosserat elasticity are employed to represent isotropic hypoplasticity, and the resulting formulae appear to encompass several empiricisms found in the literature.

    Abdominal aortic aneurysms after a kidney transplant are becoming treated more frequently owing to the extension of renal transplant in severely arteriosclerotic older patients. Renal transplant recipients with autosomal dominant polycystic kidney disease are prone to develop abdominal aortic aneurysms. We present the case of a ruptured abdominal aortic aneurysm that occurred in a renal transplant patient with autosomal dominant polycystic kidney disease. The patient was treated with emergency endovascular repair because open surgery could not be performed successfully owing to the presence of massive polycystic native kidneys and a liver that was occupying the entire peritoneal cavity. His postoperative course was uneventful without complications. The important lessons to be learned from our case are 2-fold: (1) Autosomal dominant polycystic kidney disease renal transplant recipients should be screened annually for abdominal aortic aneurysms to prevent ruptures and (2), emergency endovascular repair may be a preferred treatment in renal transplant recipients owing to its low surgical risk and success.

    This paper addresses some questions referring to shear within the context of hypoplasticity and the importance of objective stress rates in constitutive modelling. A short introduction to the stress changes due to rotations is followed by a discussion of the merits of the individual objective stress rates. It is shown that many of them differ only by terms that pertain to the constitutive description of a material. Apart from this it is shown that the Zaremba-Jaumann stress rate can lead to inconsistencies. This is, however, rather of academic importance and it appears that the use of instead of any objective stress rate produces only minor or even undiscernible errors. Finally, a question referring to limit states is addressed, which is of particular interest with respect to hypoplasticity: should the limit state be defined by =0 or by =0?

  7. A hypoplastic constitutive model for clays

    NASA Astrophysics Data System (ADS)

    Maín, D.

    2005-04-01

    This paper presents a new constitutive model for clays. The model is developed on the basis of generalized hypoplasticity principles, which are combined with traditional critical state soil mechanics. The positions of the isotropic normal compression line and the critical state line correspond to the Modified Cam clay model, the Matsuoka-Nakai failure surface is taken as the limit stress criterion and the non-linear behaviour of soils with different overconsolidation ratios is governed by the generalized hypoplastic formulation.The model requires five constitutive parameters, which correspond to the parameters of the Modified Cam clay model and are simple to calibrate on the basis of standard laboratory experiments. This makes the model particularly suitable for practical applications. The basic model may be simply enhanced by the intergranular strain concept, which allows reproducing the behaviour at very small strains. The model is evaluated on the basis of high quality laboratory experiments on reconstituted London clay. Contrary to a reference hypoplastic relation, the proposed model may be applied to highly overconsolidated clays. Improvement of predictions in the small strain range at different stress levels is also demonstrated.

  13. Hypoplastic area method for analyzing dental enamel hypoplasia.

    PubMed

    Ensor, B E; Irish, J D

    1995-12-01

    Most analyses of dental enamel hypoplasia compare frequencies of disturbed tooth types, which do not account for variability in the area of affected enamel. An alternate methodology, hypoplastic area, is presented here that accounts for this variability by combining acute and continuous enamel hypoplasia into an interval-level variable. The method compares samples based on individuals, by multiple tooth type variables, or by a single value rather than by tooth types. Use of the hypoplastic area method is illustrated by analyzing human skeletal dentitions in three archaeological samples: Meroitic Nubians from Semna South, Sudan; Anasazi from Navajo Reservoir, New Mexico; and Mogollon from Grasshopper Pueblo, Arizona. Both univariate and multivariate statistical tests are employed to assess variation in defects between individuals and samples. By incorporating measurements of continuous defects, the hypoplastic area method provides information beyond that of frequency data in comparing levels of stress. Flexibility of the method is also discussed. PMID:8599384

    We study the propagation of small disturbances in granular materials in a hypoplastic model which describes the nonlinear behaviour of granulates. The dynamic equations for one-dimensional disturbances are reduced to a system of nonlinear wave equations. The solutions for longitudinal and longitudinal-transverse waves are investigated qualitatively and numerically by the use of finite-difference schemes.

  15. Modelling Limit States Within the Framework of Hypoplasticity

    NASA Astrophysics Data System (ADS)

    Bauer, Erich

    2010-05-01

    The focus of this paper is on modelling limit stress states or so-called critical states in which a cohesionless granular body can be deformed continuously at a constant stress and a constant volume. The constitutive equations are based on the framework of hypoplasticity, which is an alternative concept to elasto-plasticity. The requirements for modelling limit stress states are studied for both a standard and a micro-polar hypoplastic model. As in a micro-polar description the stress tensor is usually non-symmetric, the question arises as to whether the result for the limit stress ratio based on the symmetric Cauchy stress tensor in the standard continuum is the same as the one obtained from the micro-polar continuum description. To this end the limit stress state is analysed under plane shearing of a lateral infinite granular strip located between parallel rough platens under a constant normal stress. It is shown that the stress ratio in the limit state obtained from the micro-polar hypoplastic model can only be the same as for the standard hypoplastic continuum model under certain conditions on the centre line of the shear band.

  17. Hypoplastic simulation of normal faults without and with clay smears

    NASA Astrophysics Data System (ADS)

    Gudehus, G.; Karcher, C.

    2007-03-01

    The main objective of the present paper is to simulate the tectonic evolution of normal faults by means of hypoplasticity. This constitutive concept is introduced with state limits for sand-like and clay-like materials. Combined with conservation laws, and initial and boundary conditions, hypoplastic relations provide normal fault patterns, which are validated by model tests. For a cross section of the Lower Rhenish Basin with synsedimentary subsidence, the observed normal fault pattern is essentially reproduced. A realistic evolution of a single normal fault with the distortion of a clay layer into a clay smear is also obtained. The potential of our method for other tectonic simulations is indicated. Animations of calculated evolutions are available in the Internet via http://www.ibf.uni-karlsruhe.de/material.html.

  18. Seismo-hypoplastic state limits of grain skeletons

    NASA Astrophysics Data System (ADS)

    Gudehus, G.

    2006-07-01

    Hypoplasticity is currently the most successful constitutive theory for soils. This paper shows how this theory can be extended to incorporate micro-seismic activity, where sound waves agitate frictional contacts, sometimes causing them to slide. These sound waves can originate within the soil, or come from the exterior. Like the temperature in visco-hypoplasticity, internally generated agitations lead to rate-dependent state limits which are described by relations of skeleton stress, void ratio and directions of strain rate. Expressions for rate-independent seismo-creep and seismo-relaxation are derived for externally generated sound waves, and confirmed by observations. This heuristic theory is apt for geotechnical applications, but the physical background has to be further clarified.

    Hypoplastic left heart syndrome has the greatest mortality rate among all CHDs and without palliation is uniformly fatal. Despite noble efforts, the aetiology of this syndrome is unknown and a cure remains elusive. The genetic and anatomic heterogeneity of hypoplastic left heart syndrome supports a rethinking of old hypotheses and warrants further investigation into the histological and vascular variations recognised with this syndrome. In an effort to elucidate the pathogenesis of hypoplastic left heart syndrome, this review will focus on its unique myocardial and coronary pathology as well as evaluate the association of hypoplastic left heart syndrome with the endocardial fibroelastosis reaction.

  3. Symmetry analysis for uniaxial compression of a hypoplastic granular material

    NASA Astrophysics Data System (ADS)

    McCue, Scott W.; Johnpillai, I. Kenneth; Hill, James M.

    2005-11-01

    A variety of modelling approaches currently exist to describe and predict the diverse behaviours of granular materials. One of the more sophisticated theories is hypoplasticity, which is a stress-rate theory of rational continuum mechanics with a constitutive law expressed in a single tensorial equation. In this paper, a particular version of hypoplasticity, due to Wu [2], is employed to describe a class of one-dimensional granular deformations. By combining the constitutive law with the conservation laws of continuum mechanics, a system of four nonlinear partial differential equations is derived for the axial and lateral stress, the velocity and the void ratio. Under certain restrictions, three of the governing equations may be combined to yield ordinary differential equations, whose solutions can be calculated exactly. Several new analytical results are obtained which are applicable to oedometer testing. In general this approach is not possible, and analytic progress is sought via Lie symmetry analysis. A complete set or “optimal system” of group-invariant solutions is identified using the Olver method, which involves the adjoint representation of the symmetry group on its Lie algebra. Each element in the optimal system is governed by a system of nonlinear ordinary differential equations which in general must be solved numerically. Solutions previously considered in the literature are noted, and their relation to our optimal system identified. Two illustrative examples are examined and the variation of various functions occuring in the physical variables is shown graphically.

  4. On the definitions of failure and critical states in hypoplasticity

    NASA Astrophysics Data System (ADS)

    Osinov, V. A.

    2008-08-01

    A granular body is said to be at failure or in a critical state if the stress state does not change while the body is continuously deformed. Within the framework of hypoplasticity, such states, generally called stationary states,are conventionally defined by the condition that an objective (the Jaumann) stress rate vanishes. However, not all stationary states attained under monotonic deformation lie within the scope of this definition. Simple shear is an example. In fact, stationary states are characterized by zero material time derivative of the stress tensor rather than zero Jaumann rate. In the present paper, we give a generalized definition of stationarity by the condition of zero material time derivative of the stress tensor. The new definition extends the set of possible stationary states and includes those which are not covered by the previous definition. Stationary states are analysed quantitatively using calibrated hypoplastic equations. It is shown numerically that, if the norm of the spin tensor is of the same order as, or smaller than, the norm of the stretching tensor, the old definition approximates all possible sationary states with sufficient accuracy.

    Pelvic actinomycosis is an infection due to actinomyces organism associated with an intra-uterine contraceptive device. This infection is often revealed by an uni- or bilateral adrenal lesion. Lesions are sometimes more extensive and affect next pelvic organs: rectum, ureter, bladder. Diagnosis is often histologic with percutaneous biopsy or surgical biopsy (laparotomy or coelio surgery). Treatment is mainly medical with prolonged use of penicillin (6 months in severely cases). Surgery must be thrifty and conservative. PMID:15050180

    This treatise focuses primarily on the clinical aspects of diagnosis and treatments of pelvic and acetabular fractures. However, considerable attention is also paid to the radiographic diagnosis of trauma and postoperative effects. The book begins with a succinct review of pelvic and acetabular anatomy and pelvic biomechanics. It continues with a radiographic classification of pelvic injury, which will represent the major source of the book's interest for radiologists. The remainder of the book is concerned with clinical management of pelvic and acetabular trauma, including preoperative planning, surgical approaches, techniques of reduction, internal fixation, eternal fixation, post-operative care, and late problems. Even throughout this later portion of the book there are extensive illustrations, including plain radiographs, computed tomographic (CT) scans, reconstructed three-dimensional CT scans, and schematic diagrams of diverse pelvic and acetabular fractures and the elementary surgical techniques for their repair.

    Three cases of a complex malformation of the hand involving syndactyly, polydactyly, and hypoplastic triphalangeal thumb are presented. In all three patients, six metacarpal bones and hypoplasticity of the thenar muscles were present. In one patient, both hands, except the most radial digits of the left hand, were completely fused by soft webs as reported by Haas and Ofodile. In two other patients, the extent of the webs differed from Haas's case, but one of them was similar to Ofodile's first case. In all instances the supernumerary digit had a triphalangeal configuration and the thenar muscles were hypoplastic, often associated with some degree of webbing. PMID:2161441

    2013-01-01

    Patients with pelvic congestion syndrome present with otherwise unexplained chronic pelvic pain that has been present for greater than 6 months, and anatomic findings that include pelvic venous insufficiency and pelvic varicosities. It remains an underdiagnosed explanation for pelvic pain in young, premenopausal, usually multiparous females. Symptoms include noncyclical, positional lower back, pelvic and upper thigh pain, dyspareunia, and prolonged postcoital discomfort. Symptoms worsen throughout the day and are exacerbated by activity or prolonged standing. Examination may reveal ovarian tenderness and unusual varicosities—vulvoperineal, posterior thigh, and gluteal. Diagnosis is suspected by clinical history and imaging that demonstrates pelvic varicosities. Venography is usually necessary to confirm ovarian vein reflux, although transvaginal ultrasound may be useful in documenting this finding. Endovascular therapy has been validated by several large patient series with long-term follow-up using standardized pain assessment surveys. Embolization has been shown to be significantly more effective than surgical therapy in improving symptoms in patients who fail hormonal therapy. Although there has been variation in approaches between investigators, the goal is elimination of ovarian vein reflux with or without direct sclerosis of enlarged pelvic varicosities. Symptom reduction is seen in 70 to 90% of the treated females despite technical variation. PMID:24436564

    Abstract Although there are many studies of people with complete or partial hypogenesis of the corpus callosum (CC), little is understood about the hypoplastic CC in which all structures are present but thinned. Spina bifida myelomeningocele (SBM) is a model organism for such studies because many have either a hypogenetic or hypoplastic CC. We used diffusion tensor tractography (DTT) to evaluate the hypoplastic CC in SBM and its relation to interhemispheric functions and intelligence quotient (IQ). Participants were individuals with SBM and an intact or hypoplastic CC (n=28), who were compared to a typically developing comparison group (n=32). Total and regional DTT volume and integrity measures (fractional anisotropy, axial diffusivity, and radial diffusivity) of the CC were related to measures of intelligence (IQ), bimanual motor functioning, and dichotic auditory performance. As predicted, DTT showed variations in volume and integrity that were maximized in the entire CC and the posterior CC. IQ correlated with entire CC volume, anterior and posterior regional CC volumes, and also with measures of integrity. Bimanual motor functioning correlated with the anterior and posterior volumes of the CC but not with any integrity measures. Axial diffusivity in the posterior CC was negatively correlated with right ear dichotic listening performance. The hypoplastic CC is not macrostructurally or microstructurally intact in SBM, even when it appears radiologically intact. Both volume and integrity of the posterior regions were related to reductions in IQ and to interhemispheric processing. These findings may transfer to other disorders characterized by a hypoplastic CC. PMID:25014561

    2015-01-01

    OBJECTIVE To examine the survival of infants with hypoplastic left heart syndrome (HLHS) and potential influence of demographic and clinical characteristics on survival using population-based data. METHODS Infants with nonsyndromic HLHS (n = 212) born between 1979 and 2005 were identified through the Metropolitan Atlanta Congenital Defects Program. Vital status was ascertained through 2009 based on linkage with vital records. We estimated Kaplan-Meier survival probabilities stratified by select demographic and clinical characteristics. RESULTS The overall survival probability to 2009 was 24% and significantly improved over time: from 0% in 1979–1984 to 42% in 1999–2005. Survival probability was 66% during the first week, 27% during the first year of life, and 24% during the first 10 years. Survival of very low and low birth weight or preterm infants and those born in high-poverty neighborhoods was significantly poorer. For children with information on surgical intervention (n = 88), the overall survival was 52%, and preterm infants had significantly poorer survival (31%) compared with term infants (56%). For children who survived to 1 year of age, long-term survival was ~90%. CONCLUSIONS Survival to adolescence of children with nonsyndromic HLHS born in metropolitan Atlanta has significantly improved in recent years, with those born full term, with normal birth weight, or in a low-poverty neighborhood having a higher survival probability. Survival beyond infancy to adolescence is high. A better understanding of the growing population of survivors with HLHS is needed to inform resource planning. PMID:26391936

    Hypoplastic left heart syndrome (HLHS) affects infants and is uniformly fatal without surgery. Post-surgery mortality rates are highly variable and dependent on postoperative management. The high mortality after the first stage surgery usually occurs within the first few days after procedure. Typically, the deaths are attributed to the unstable balance between the pulmonary and systemic circulations. An experienced team of physicians, nurses, and therapists is required to successfully manage the infant. However, even the most experienced teams report significant mortality due to the extremely complex relationships among physiologic parameters in a given patient. A data acquisition system was developed for the simultaneous collection of 73 physiologic, laboratory, and nurse-assessed variables. Data records were created at intervals of 30 seconds. An expert-validated wellness score was computed for each data record. A training data set consisting of over 5000 data records from multiple patients was collected. Preliminary results demonstratd that the knowledge discovery approach was over 94.57% accurate in predicting the "wellness score" of an infant. The discovered knowledge can improve care of complex patients by development of an intelligent simulator that can be used to support decisions.

    We sought to evaluate the relation of a prenatal diagnosis (preDx) with morbidity and mortality during the initial hospitalization in a contemporary cohort of patients with hypoplastic left heart syndrome (HLHS). A retrospective study of patients with HLHS presenting from 1999 to 2010 was performed. Patients with genetic disorders or a gestational age <34 weeks or who had intentionally received comfort care only were excluded. Of the 81 patients meeting the study criteria, 49 had a preDx and 32 were diagnosed postnatally (postDx). Birth weight (median 3.0 vs 3.4 kg; p = 0.007) and gestational age (median 38 vs 39 weeks; p <0.001) were lower in the preDx than in the postDx patients. Preoperatively, the postDx patients were intubated more frequently (97% vs 71%, p = 0.004) and ventilated longer (median 96 vs 24 hours, p = 0.005) than the preDx patients. They also had more preoperative acidosis, multiorgan failure, tricuspid valve regurgitation, and right ventricular dysfunction. Of the 73 patients undergoing surgery, no difference in survival was seen between the preDx and postDx groups (91% vs 89%). The median duration of postoperative ventilation was 7 days and the median length of stay was 36 days for the 66 survivors, with no difference between the 2 groups. Postoperative morbidities, including chylothorax and infection, were also similar in the preDx and postDx patients. No studied preoperative factor was associated with death, duration of postoperative ventilation, or length of stay. In conclusion, our recent experience has shown that preDx of HLHS was not associated with a survival advantage, fewer postoperative complications, or shorter length of stay. Improved preoperative status was observed in the preDx patients; however, they were born earlier with a lower birthweight. What effect these factors might have on longer term morbidity remains unknown. PMID:21624547

    2014-10-01

    The successful treatment of women with vestibulodynia and its associated chronic pelvic floor dysfunctions requires interventions that address a broad field of possible pain contributors. Pelvic floor muscle hypertonicity was implicated in the mid-1990s as a trigger of major chronic vulvar pain. Painful bladder syndrome, irritable bowel syndrome, fibromyalgia, and temporomandibular jaw disorder are known common comorbidities that can cause a host of associated muscular, visceral, bony, and fascial dysfunctions. It appears that normalizing all of those disorders plays a pivotal role in reducing complaints of chronic vulvar pain and sexual dysfunction. Though the studies have yet to prove a specific protocol, physical therapists trained in pelvic dysfunction are reporting success with restoring tissue normalcy and reducing vulvar and sexual pain. A review of pelvic anatomy and common findings are presented along with suggested physical therapy management. PMID:25108498

    The family physician dealing with gynecologic pelvic pain (acute or chronic) enters at the beginning of the problem as diagnostician, refers the patient to a specialist in the interim, and resumes care in the follow-up period. Patients with chronic pelvic pain (pelvic pain that has lasted for at least six months) can be difficult to treat because they often have a history of dysfunctional family life, sexual and marital problems, and often a hidden history of sexual molestation or incest. The family physician can best care for the patient with empathy, a long ventilated history, complete physical and pelvic examination, and pelvic ultrasonograpy if necessary. Laparoscopy normally shows pelvic adhesions in one third of these patients, minimal endometriosis in one third, and a normal pelvis in the final third. The family physician should specifically reassure patients with normal results that they do not have cancer. The ideal therapy combines both stimulation-produced analgesia and treatment of the psychological, emotional, sociological, and environmental aspects of the disease. PMID:21248970

    1996-01-01

    OBJECTIVE: The authors review their experience with staged reconstructive surgery for hypoplastic left heart syndrome (HLHS) and assess current outcome for this condition. SUMMARY BACKGROUND DATA: Once considered a uniformly fatal condition, the outlook for newborns with HLHS has been altered dramatically with staged reconstructive procedures. Refinements in operative technique and perioperative management have been largely responsible for this improved outlook. METHODS: The authors reviewed their experience with 158 consecutive patients undergoing stage 1 reconstruction with a Norwood procedure from January 1990 to August 1995. All patients had classic HLHS, defined as a right ventricular dependent circulation in association with atresia or severe hypoplasia of the aortic valve. RESULTS: There were 120 hospital survivors. Among the 127 patients considered at standard risk, survival was significantly higher than that for the 31 patients with important risk factors. Adverse survival was associated most strongly with significant associated noncardiac congenital conditions and severe preoperative obstruction to pulmonary venous return. Second-stage reconstruction with the hemi-Fontan procedure was performed in 106 patients, with 103 hospital survivors and one late death. Three of the late survivors were not considered candidates for the Fontan procedure. To date, the Fontan procedure has been completed in 62 patients, with 53 survivors. Deaths after the Fontan procedure occurred early in our experience and were mostly secondary to left pulmonary artery stenosis or hypoplasia. Significant or potentially significant morbid conditions were noted in 25 of the 120 hospital survivors. Neurologic conditions were found in 6% and cardiovascular conditions in 10%, including dysrhythmia, left pulmonary artery thrombosis, and chronic pleural effusions. Among the patients considered at standard risk with typical anatomy, actuarial survival was 69 +/- 8% at 5 years. Survival was 71 +/- 17% at 5 years for standard risk patients with variant anatomy and 58 +/- 9% for the entire cohort of 158 patients. The largest decrease in survival occurred in the first month of life and late deaths primarily affected those patients in the high-risk group. CONCLUSIONS: Staged reconstruction has significantly improved the intermediate-term outlook for patients with HLHS. Factors addressing improvements in early (< 1 month) first-stage survival would be expected to add significantly to an overall improved late outcome. Currently employed refinements in operative technique are associated with eliminating or reducing pulmonary artery distortion and dysrhythmia. PMID:8813267

    2004-03-01

    The paper deals with the comparison of a non-local and a polar (Cosserat) hypoplastic model. The hypoplastic constitutive law in the version of von Wolffersdorff is chosen as local reference model. For the comparison the results of biaxial tests on dense Hostun Rf sand are predicted with both enhanced models. The comparison is based on a strict separation of input data from triaxial- and oedometer tests and output data from biaxial tests. The comparison is drawn in terms of the shear band width, the load-displacement curves and the influence of the pressure level. Finally, the non-local and the polar hypoplastic model are applied on the strip foundation problem. Copyright

    2010-06-01

    Atrial septal restriction is estimated to occur in up to 22% of patients with hypoplastic left heart syndrome and is associated with poor prognosis postnatally. Atrial septal aneurysms are known to be more prevalent in patients with congenital heart disease and atrial septal restriction due to elevated atrial pressures in fetal life. We report the case of a newborn with hypoplastic left heart syndrome, restrictive interatrial communication, and atrial septal aneurysm. The latter led to formation of a large intralimbic hematoma within it, which resulted in complete obstruction of the interatrial communication after birth, which led to death. We suggest that in addition to the known associated problems encountered in patients with hypoplastic left heart syndrome and restrictive interatrial communication, aneurysmal formation of the interatrial septum should alert the fetal and postnatal echocardiographer further, and careful assessment and follow-up is recommended.

    We report a case of a fetus with hypoplastic left heart syndrome in addition to an anomalous vessel extending from the descending thoracic aorta to the basal segments of the lower left lung without sequestration. The concurrence of these 2 congenital abnormalities is extremely rare and unreported in the existing literature. The anomalous vessel to the left lung may cause increased pulmonary vascular resistance, which has implications for the long-term management of hypoplastic left heart syndrome via the Fontan procedure.

    A case of pelvic actinomycosis is presented. The patient is 42-year-old female with a 5 weeks history of pelvic pain. An intrauterine device (IUD) was taken out 3 weeks ago. There is a lump length 9 cm between rectus muscles. Ultrasound, magnetic resonance imaging (MRI) and histology are used to make the diagnosis. Actinomycosis can mimic the tumour disease. The definitive diagnosis requires positive anaerobic culture or histological identification of actinomyces granulas. A long lasting antibiotic therapy is performed. PMID:22373804

  5. Current Concepts of Pelvic Congestion and Chronic Pelvic Pain

    PubMed Central

    2001-01-01

    Chronic pelvic pain in women is a common and disabling illness caused by numerous organic pathologies usually accompanied by varying psychological dysfunctions. Many patients may receive misdiagnosis, misdirected therapies, or do not seek help at all. Pelvic congestion may be responsible for pain in patients without more common diseases, such as endometriosis and pelvic adhesions, among others. Our view of this condition is evolving. In the United States, this medical condition remains controversial. More recent research from the United Kingdom has caused a fresh look at the diagnosis and treatment of chronic pelvic pain produced by pelvic congestion. Potentially, many patients may benefit from a reconsideration of this approach. PMID:11394421

    Evisceration of the pelvic organs (EPO) is a fairly uncommon surgical treatment that removes all organs from a patient's pelvic cavity. We use gracilis musculocutaneous flap to repair pelvic floor after EPO. Over the period from November 2013 to December 2014 we carried out EPO with reconstructive repair of the pelvic floor with gracilis musculocutaneous flap in 10 patients with locally advanced pelvic tumors. We describe the surgical procedure and surgical outcomes in these patients. Mean age of the patients was 55 years. Mean duration of EPO with the pelvic floor repair was 285 min., mean blood loss--595 mL and the average length of hospital stay--19 days. Gracilis musculocutaneous flap has a sufficient arterial supply and mobility for pelvic floor reconstruction. Necrosis of flap's distal edge occurred in one of the 10 clinical cases, while the remaining flaps were fully preserved. Complete healing of wounds with no signs of weakening of the pelvic floor muscles was observed in all cases. Pelvic floor reconstruction is an essential procedure in order to reduce complications associated with the evisceration of the pelvic organs. The Gracilis musculocutaneous flap is the logical alternative to repair pelvic floor defect. It does not contribute to complications like functional deficiency of the lower limbs, complications of stoma formation or weakening of the muscles of the anterior abdominal wall. PMID:26390558

    Abdominal-pelvic actinomycosis is often mistaken for other conditions, presenting a preoperative diagnostic challenge. In a 46-year-old female, computed tomography showed an abdominal-pelvic retroperitoneal mass extending from the lower pole of the right kidney to the lower pelvis. The patient had a 3-year history of intrauterine device. The mass appeared to involve the ascending colon, cecum, distal ileum, right Fallopian tube and ovary, and ureter anteriorly and the psoas muscle posteriorly. The resection of retroperitoneal mass, distal ileum appendicectomy, right hemicolectomy, and right salpingo-oophorectomy was performed. The postoperative period was uneventful. Penicillin therapy was given for six months without any complication. The retroperitoneal mass measured 4.5 × 3.5 × 3 cm, surrounded adjacent organs and histologically showed inflammatory granulomatous tissue, agglomeration of filaments, and sulfur granules of Actinomyces, with positive reaction with periodic acid Schiff. Right tubo-ovarian abscess was present. Abdominalpelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intrauterine device. PMID:21904441

    In the present study, the Goodman-Cowin theory is extended to incorporate plastic features to construct an elasto-visco-plastic constitutive model for flowing dry granular materials. A thermodynamic analysis, based on the Müller-Liu entropy principle, is performed to derive the equilibrium expressions of the constitutive variables. Non-equilibrium responses are proposed by use of a quasi-linear theory, in particular a hypoplastic-type relation is introduced to model the internal friction and plastic effects. It is illustrated that the Goodman-Cowin theory can appropriately be extended to include frictional effects into the evolution equation of the volume fraction (i.e. the so-called balance of equilibrated force) and the equilibrium expression of the Cauchy stress tensor. The implemented model is applied to investigate conventional steady isothermal granular flows with incompressible grains, namely simple plane shear, inclined gravity-driven and vertical channel-flows, respectively. Numerical results show that the hypoplastic effect plays a significant role in the behaviour of a flowing granular material. The obtained profiles of the velocity and the volume fraction with hypoplastic features are usually sharper and the shear-thinning effect is more significant than that without such plastic effects. This points at the possible wide applicability of the present model in the fields of granular materials and soil mechanics. In addition, the present paper also provides a framework for a possible extension of the hypoplastic theories which can be further undertaken. Copyright

  12. Airway smooth muscle dysfunction precedes teratogenic congenital diaphragmatic hernia and may contribute to hypoplastic lung morphogenesis.

    Fetal intervention aims to improve lung growth and survival in congenital diaphragmatic hernia (CDH). Airway smooth muscle (ASM) is important in lung development: ASM progenitors produce a key growth factor for lung morphogenesis (fibroblast growth factor 10); ASM contractility is also coupled to growth. ASM hyperreactivity occurs in postnatal CDH and may exacerbate barotrauma via impaired lung compliance. We hypothesize that ASM hyperreactivity and its sequelae are based on an early developmental lesion of ASM activity in hypoplastic lung. Sprague-Dawley rats were fed 100 mg nitrofen on Day 9.5 of pregnancy to induce lung hypoplasia in offspring (controls had vehicle alone). Normal and hypoplastic lung primordia were cultured from Day 13.5 of gestation at 37 degrees C in 5% CO(2) and loaded at 54 or 78 h with Ca(2+)-sensitive indicators: Fluo-4 for confocal imaging and Indo-1 or Fura-2 for photometric measurements of [Ca(2+)](i). Hypoplastic lung features spontaneous propagating ASM Ca(2+) transients with reduced frequency, increased amplitude, and significantly prolonged plateau duration, relative to control lung. Nonetheless, hypoplastic lung exhibits normal requirement for extracellular calcium entry and intracellular calcium release in initiation and regulation of ASM Ca(2+) waves. Early ASM dysfunction in lung hypoplasia is apparent as specific anomalies of Ca(2+) transients that indicate a problem with plasmalemmal ion channels/action potential generation. Elucidation of such an ASM lesion may allow pharmacologic amelioration not only of ASM hyperreactivity and its sequelae, but also of hypoplastic lung growth itself. PMID:16728706

    The aim of this study was to investigate the effects of various renal pelvic pressure gradients on nephrons with purulent infection. Five miniature test pigs were selected. One side of the kidney was used to prepare the pyonephrosis model and the other side was used as the healthy control. A piezometer and a water fill tube were inserted into the renal pelvis through the ureter. Prior to perfusion, punctures were made on the healthy and purulent sides of the kidneys to obtain tissues (as controls). Subsequently, a puncture biopsy was conducted on the kidneys at five pressure levels: 10, 20, 30, 40 and 50 mmHg. Once the renal pelvic pressure had increased, the healthy and injured kidneys presented pathological changes, including dilation of the renal tubule and capsule and compression of the renal glomerulus. When the renal pelvic pressure exceeded 20 mmHg, the injured kidney presented more damage. Electron microscopy revealed that the increase in pressure resulted in the following: the podocyte gap widened, the epithelial cells of the renal capsule separated from the basement membrane, the basement membrane thickness became uneven, the continuity of the basement membrane was interrupted at multiple positions and the renal tubule microvillus arrangement became disorganised. The manifestations in the pyonephrosis model were more distinct compared with those in the healthy kidney. As the renal pelvic pressure exceeds 20 mmHg under a renal purulent infection status, the nephrons become damaged. The extent of the damage is aggravated as the pressure is increased. PMID:23737886

  20. Fluid dynamic modelling of renal pelvic pressure during endoscopic stone removal

    2015-11-01

    Endoscopic kidney stone removal procedures are known to increase internal pressure in the renal pelvis, the kidney's urinary collecting system. High renal pelvic pressure incites systemic absorption of irrigation fluid, which can increase the risk of postoperative fever and sepsis or the unwanted absorption of electrolytes. Urologists choose the appropriate surgical procedure based on patient history and kidney stone size. However, no study has been conducted to compare the pressure profiles of each procedure, nor is there a precise sense of how the renal pelvic pressure scales with various operational parameters. Here we develop physical models for the flow rates and renal pelvic pressure for various procedures. We show that the results of our models are consistent with existing urological data on each procedure and that the models can predict pressure profiles where data is unavailable.

  1. Functional anorectal and pelvic pain.

    PubMed

    2001-03-01

    Functional anorectal and pelvic pain syndromes represent a diverse group of disorders that affect the quality of life and about which many physicians possess little understanding. Nongynecologic causes include levator ani syndrome, proctalgia fugax, and coccygodnia, which can often be distinguished by careful history and physical examination. In women, chronic pelvic pain may arise from the uterus, cervix, ovaries, or from endometriosis and pelvic adhesions. This article reviews these diverse disorders and the approach to diagnosis and management. PMID:11394033

    OBJECTIVE The objective was to estimate the effect of vaginal childbirth and other obstetric exposures on pelvic muscle strength 6–11 years after delivery and to investigate the relationship between pelvic muscle strength and pelvic floor disorders. METHODS Among 666 parous women, pelvic muscle strength was measured with a perineometer 6–11 years after delivery. Obstetric exposures were classified by review of hospital records. Pelvic floor outcomes, including stress incontinence, overactive bladder, anal incontinence, and prolapse symptoms, were assessed with a validated questionnaire. Pelvic organ support was assessed using the Pelvic Organ Prolapse Quantification system. Kruskal-Wallis tests were used to estimate the univariable associations of obstetric exposures and pelvic floor outcomes with peak muscle strength. Stepwise multivariable linear regression models were used to estimate the association between obstetric exposures and muscle strength. RESULTS In comparison with women who delivered all of their children by cesarean, peak muscle strength and duration of contraction were reduced among women with a history of vaginal delivery (39 compared with 29 cm H2O, P<.001). Pelvic muscle strength was further reduced after history of forceps delivery (17 cm H2O, P<.001). After vaginal delivery, reduced pelvic muscle strength was associated with symptoms of anal incontinence (P=.028) and pelvic organ prolapse on examination (P=.025); these associations were not observed among those who had delivered exclusively by cesarean. CONCLUSION Pelvic muscle strength almost a decade after childbirth is affected by vaginal delivery and by forceps delivery. Although statistically significant, some of the differences observed were small in magnitude. PMID:23090518

  3. A comparative study of the hypoplasticity and the fabric-dependent dilatant double shearing models for granular materials

    2007-04-25

    In this paper, we consider the mechanical response of granular materials and compare the predictions of a hypoplastic model with that of a recently developed dilatant double shearing model which includes the effects of fabric. We implement the constitutive relations of the dilatant double shearing model and the hypoplastic model in the finite element program ABACUS/Explicit and compare their predictions in the triaxial compression and cyclic shear loading tests. Although the origins and the constitutive relations of the double shearing model and the hypoplastic model are quite different, we find that both models are capable of capturing typical behaviours of granular materials. This is significant because while hypoplasticity is phenomenological in nature, the double shearing model is based on a kinematic hypothesis and microstructural considerations, and can easily be calibrated through standard tests.

  4. Hybrid Palliation for Neonates With Hypoplastic Left Heart Syndrome: Current Strategies and Outcomes

    2010-01-01

    In the last decade the hybrid procedure has emerged as an alternative stage I palliation in neonates with hypoplastic left heart syndrome (HLHS). This review discusses the historical aspect, surgical and interventional techniques, current outcomes and future direction of this procedure. Hybrid palliation yields equivalent but not superior stage I palliation survival and comparable 1-year survival to conventional Norwood palliation, comparable prestage II hemodynamics and pulmonary artery growth, and preserved ventricular function in stage II palliation. Hybrid palliation utilizes significantly less resource and shortens postoperative recovery. In comprehensive stage II palliation the impact of pulmonary artery reconstruction on subsequent pulmonary artery growth has not been determined and should be further investigated. A prospective, randomized trial is warranted to compare these two surgical strategies for neonates with hypoplastic left heart syndrome. PMID:20339493

    The occurrence of pulmonary venous obstruction after total cavopulmonary connection with intraatrial lateral tunnel is a rare occurrence. We present two cases of hypoplastic left heart syndrome with restrictive interatrial communication presenting late after this type of modified Fontan repair. This occurred even after complete excision of the atrial septum at the time of Stage 1 Norwood in both cases. A novel approach to this problem of resecting the roof of the coronary sinus was utilized to enlarge the interatrial communication. PMID:14667654

    2014-01-01

    Pelvic insufficiency fractures may occur in the absence of trauma or as a result of low-energy trauma in osteoporotic bone. With a growing geriatric population, the incidence of pelvic insufficiency fracture has increased over the last 3 decades and will continue to do so. These fractures can cause considerable pain, loss of independence, and economic burden to both the patient and the health care system. While many of these injuries are identified and treated based on plain radiographs, some remain difficult to diagnose. The role of advanced imaging in these cases is discussed. In addition to treating the fracture, medical comorbidities contributing to osteoporosis should be identified and corrected. Specific attention has been given to 25-OH serum vitamin D screening and repletion. Treatment generally consists of providing pain control and assisting patients with mobilization while allowing weight bearing as tolerated. In those unable to do so, invasive techniques such as sacroplasty as well as internal fixation may be beneficial. The role of operative fixation in insufficiency fractures is also discussed.

    Pelvic actinomycosis is a rare chronic suppurative granulomatous disease associated with an intrauterine contraceptive device. Next pelvic organs can be affected but also more distant organs, to lead to different clinical situations. The diagnosis is therefore often difficult. We report here the case of a woman who presents a particular extensive pelvic actinomycosis diagnosed after surgical treatment with important morbidity. This case shows the interest of evoking the diagnosis in an evocative clinical context, doing the necessary exams to confirm the hypothesis, favouring medical treatment and reserving surgical treatment for particular situations.

    Upper urinary tract peristalsis is generated in the proximal renal pelvis that connects to the renal parenchyma at the pelvis-kidney junction. It may be exposed to the high renal endothelin-1 (ET-1) concentrations. Dietary NaCl restriction increases renal pelvic ETA receptor expression. We investigated the contribution of ETA and ETB receptors to ET-1-stimulated rat renal pelvic contractions and whether the sensitivity of renal pelvic contractile activity to ET-1 stimulation increases with dietary NaCl restriction. We tested whether ET-1-induced contractile activity depends on cyclooxygenase (COX)-1 or -2 and to what extent spontaneous as well as agonist-induced peristalsis depends on Rho kinases (ROCK). Contractions of isolated renal pelvises were investigated by myography. ET-1 concentration-dependently increased pelvic contractile activity up to 400% of basal activity. ETA but not ETB receptor blockade inhibited ET-1-induced pelvic contractions. Basal and ET-1-stimulated contractions were similar in renal pelvises from rats on a high-NaCl diet or on a NaCl-deficient diet. COX-1 inhibition reduced spontaneous and almost completely blocked the ET-1-induced pelvic contractions. ROCK inhibition reduced spontaneous and ET-1 stimulated pelvic contractile activity by 90%. RT-PCR revealed that both ROCK isoenzymes are present in the renal pelvic wall. Western blot analyses did not show increased phosphorylation of ROCK substrates myosin phosphatase target subunit 1, ezrin, radixin, and moesin in ET-1-treated isolated renal pelvises. ET-1 is a powerful ETA receptor-dependent activator of renal pelvic contractions. COX-1 and ROCK activity are required for the ET-1 effects on pelvic contractions, which are not significantly affected by dietary NaCl intake. PMID:20861282

    We report a technique to palliate hypoplastic left heart syndrome, with no PDA stenting, but with double polytetrafluoroethylene shunt from pulmonary artery to ascending and descending aorta by combined thoracotomies. A 30-day-old female was operated with this technique. Five months after first operation, the child was submitted to Norwood/Glenn operation. Good hemodinamic recovery and initial clinical evolution was observed. The child was extubated in 8th post operatory day and reentubated in the next day due to pulmonary infection. Despite antibiotic treatment, the child died after systemic infectious complications. PMID:22029529

    The postnatal survival of patients with congenital cardiac defects such as hypoplastic left heart syndrome (HLHS) is dependent on the patency of the ductus arteriosus and the presence of an unrestrictive atrial septal defect (ASD). We report a six week old infant with HLHS and tricuspid valve regurgitation with restrictive ASD. Transfemoral balloon atrial septostomy provided temporary relief but further attempts were not possible. A transhepatic venous approach to stent the atrial communication was technically successful. This approach may be the only access for certain infant cardiac catheterization interventions, permitting the use of a large delivery system (≥ 8 Fr). PMID:24532371

Evaluation of CPP requires obtaining a careful history including not only obstetrical and gynecologic information but also screening for gastrointestinal, urologic, musculoskeletal, and neurological disorders. A detailed physical examination is also necessary. Management of CPP depends largely on the cause. Gynecologic causes include endometriosis, pelvic inflammatory disease, adhesive disease, pelvic congestion syndrome, ovarian retention syndrome, ovarian remnant syndrome, adenomyosis, and leiomyomas. Some non-gynecologic causes are interstitial cystitis/painful bladder syndrome, irritable bowel syndrome, pelvic floor tension myalgia, and abdominal myofascial pain syndrome. Treatments may be directed toward specific causes or may be targeted to general pain management. The most effective therapy may involve using both approaches. The diagnosis and treatment of each of the above disorders, and the management of CPP itself, is discussed. PMID:20938429

    Pelvic cancers are among the most frequently diagnosed cancers worldwide. Treatment of patients requires a multidisciplinary approach that frequently includes radiotherapy. Gastrointestinal (GI) radiation-induced toxicity is a major complication and the transient or long-term problems, ranging from mild to very severe, arising in non-cancerous tissues resulting from radiation treatment to a tumor of pelvic origin, are actually called as pelvic radiation disease. The incidence of pelvic radiation disease changes according to the radiation technique, the length of follow up, the assessment method, the type and stage of cancer and several other variables. Notably, even with the most recent radiation techniques, i.e., intensity-modulated radiotherapy, the incidence of radiation-induced GI side effects is overall reduced but still not negligible. In addition, radiation-induced GI side effects can develop even after several decades; therefore, the improvement of patient life expectancy will unavoidably increase the risk of developing radiation-induced complications. Once developed, the management of pelvic radiation disease may be challenging. Therefore, the prevention of radiation-induced toxicity represents a reasonable way to avoid a dramatic drop of the quality of life of these patients. In the current manuscript we provide an updated and practical review on the best available evidences in the field of the prevention of pelvic radiation disease. PMID:25664197

    Pelvic-perineal dysfunctions, are the most common diseases in women after pregnancy. Urinary incontinence and genital prolapsy, often associated, are the most important consequences of childbirth and are determined by specific alterations in the structure of neurological and musculo-fascial pelvic support. Causation is difficult to prove because symptom occur remote from delivery. Furthermore it is unclear whether changes are secondary to the method of childbirth or to the pregnancy itself. This controversy fuels the debate about whether or not women should be offered the choice of elective caesarean delivery to avoid the development of subsequent pelvic floor disfunction. But it has been demonstrated that pregnancy itself, by means of mechanical changes of pelvic statics and changes in hormones, can be a significant risk factor for these diseases. Especially is the first child to be decisive for the stability of the pelvic floor. During pregnancy, the progressive increase in volume of the uterus subject perineal structures to a major overload. During delivery, the parties present and passes through the urogenital hiatus leading to growing pressure on the tissues causing the stretching of the pelvic floor with possible muscle damage, connective tissue and / or nervous. In this article we aim to describe genitourinary post partum changes with particular attention to the impact of pregnancy or childbirth on these changes. PMID:22439048

  2. Variable long-term outcomes from cochlear implantation in children with hypoplastic auditory nerves.

    This paper describes the outcomes in six children with hypoplastic cochlear nerves, demonstrated on magnetic resonance imaging who were selected for implantation because they had clear responses to sound, with hearing aids. In four of the six children the internal auditory canals were abnormally narrow; however in the remaining two the internal auditory canals were of normal width. After activation of their devices, all six children had auditory thresholds within the normal range for implanted congenitally deaf children. However the progress of all these children after 2 to 6 years of implant use turned out to be disappointing. Five of the children developed only the ability to detect the presence of sound, and were unable to discriminate accurately between speech sounds. They remain at Category of Auditory Performance (CAP) level 2: sign is their primary mode of communication. All five children also remain at Speech Intelligibility Rating (SIR) level 2, with unintelligible connected speech. The sixth child was able to develop some understanding of common phrases through listening alone, however he remains at CAP level 4 and his SIR level also remains at 2. The benefit of cochlear implantation in this group of children is likely to be considerably restricted. In specific cases it may be appropriate to offer a cochlear implant to a child with hypoplastic auditory nerves but careful counselling of the family about likely outcomes is essential.

    Female genital tract microbiota play a crucial role in maintaining health. Disequilibrium of the microbiota has been associated with increased risk of pelvic infections. In recent years, culture-independent molecular techniques have expanded understanding of the composition of genital microbiota and the dynamic nature of the microbiota. There is evidence that upper genital tract may not be sterile and may harbor microflora in the physiologic state. The isolation of bacterial vaginosis-associated organisms in women with genital infections establishes a link between pelvic infections and abnormal vaginal flora. With the understanding of the composition of the microbiota in healthy and diseased states, the next logical step is to identify the function of the newly identified microbes. This knowledge will further expand our understanding of the causation of pelvic infections, which may lead to more effective prevention and treatment strategies. PMID:24390920

    2014-01-01

    Quality of life is adversely affected by pelvic organ prolapse, the prevalence of which is increasing because of the persistently growing older population. Today, the tension-free vaginal mesh kit has grown in popularity owing to its comparable cure rate to traditional reconstructive surgery and the feasibility of an early return to normal life. However, significant debate remains over the long-term cure rate and the safety of tension-free vaginal mesh in the United States. The U.S. Food and Drug Administration recommends obtaining informed consent about the safety and cure rate when the patient chooses surgery using the tension-free vaginal mesh kit or meshes before surgery. The goal of surgery for pelvic organ prolapse is the restoration of anatomic defects. This review article provides an overview of basic surgical techniques and the results, advantages, and disadvantages of surgery for pelvic organ prolapse. PMID:25405010

  15. Oseltamivir-warfarin interaction in hypoplastic left heart syndrome: case report and review.

    Wagner, Jonathan; Abdel-Rahman, Susan M

    2015-05-01

    An 8-year-old boy with hypoplastic left heart syndrome with a previous history of thrombosis within the inferior vena cava receiving stable warfarin dosing for anticoagulation was diagnosed with influenza B. He was subsequently placed on oseltamivir therapy according to the Centers for Disease Control and Prevention clinical practice guidelines. During the hospitalization, his international normalized ratio steadily increased to supratherapeutic levels and returned to baseline after discontinuation of oseltamivir therapy. This case represents a drug-drug interaction that has not been previously reported in children or adolescents. An extensive review of the pharmacokinetic and pharmacodynamic literature did not uncover a definitive etiology for this interaction. However, several undefined aspects in each drug's disposition pathway need further elucidation. Until this interaction is understood, caution is warranted, and close monitoring of the international normalized ratio should be performed in all patients prescribed oseltamivir concomitantly with warfarin.

    2014-01-01

    Due to the complex anatomical and haemodynamic consequences of hypoplastic left heart syndrome (HLHS), patients with the condition require multistage surgical and supportive interventional treatment. Percutaneous interventions may be required between each stage of surgical palliation, sometimes simultaneously with surgery as hybrid interventions, or after completion of multistage treatment. Recent advances in the field of interventional cardiology, including new devices and techniques, have significantly contributed to improving results of multistage HLHS palliation. Knowledge of the potential interventional options as well as the limitation of percutaneous interventions will enable the creation of safe and effective treatment protocols in this highly challenging group of patients. In this comprehensive review we discuss the types, goals, and potential complications of transcatheter interventions in patients with HLHS. PMID:25489307

    2001-04-01

    The problem of the symmetric quasi-static large-strain expansion of a cavity in an infinite granular body is studied. The body is assumed to be dry or fully drained so that the presence of the pore water can be disregarded. Both spherical and cylindrical cavities are considered. Numerical solutions to the boundary value problem are obtained with the use of the hypoplastic constitutive relation calibrated for a series of granular soils. As the radius of the cavity increases, the stresses and the density on the cavity surface asymptotically approach limit values corresponding to a so-called critical state. For a given soil, the limit values depend on the initial stresses and the initial density. A comparison is made between the solutions for different initial states and different soils. Applications to geotechnical problems such as cone penetration test and pressuremeter test are discussed.

  18. Numerical investigations of shear localization in a micro-polar hypoplastic material

    2003-04-01

    In this paper a micro-polar continuum approach is proposed to model the essential properties of cohesionless granular materials like sand. The model takes into account the influence of particle rotations, the mean grain size, the void ratio, the stresses and couple stresses. The constitutive equations for the stresses and couple stresses are incrementally non-linear and based on the concept of hypoplasticity. For plane strain problems the implementation of the model in a finite element program is described. Numerical studies of the evolution of micro-polar effects within a granular strip under plane shearing are presented. It is shown that the location and evolution of shear localization is strongly influenced by the initial state and the micro-polar boundary conditions. For large shearing the state quantities tend towards a stationary state for which a certain coupling between the norm of the stress deviator and the norm of the couple stress tensor can be derived.

    Tricuspid regurgitation (TR) is known to be a risk factor for mortality in the surgical management of patients with hypoplastic left heart syndrome (HLHS). Concomitant repair for TR should be considered when the TR is moderate to severe to achieve successful Fontan completion. The present case was a 20-month-old girl who was diagnosed with HLHS (mitral atresia and aortic atresia). She underwent a Norwood procedure as the first palliation followed by a Glenn procedure. After that, she gradually developed TR, which progressed to a severe state at the time of the Fontan procedure. An edge-to-edge tricuspid valve repair, in which the anterior and septal leaflets were sutured together, was performed simultaneously with the extracardiac Fontan procedure. Discharge echocardiography revealed that the degree of TR was less than mild. The technique is simple, not time-consuming, and may be an effective adjunct for successful completion of the Fontan procedure in these patients. PMID:18066643

    2016-02-01

    Hypoplastic left heart syndrome is a severe form of congenital heart disease that results in single-ventricle physiology. Although surgical palliation in infants with this syndrome is widely agreed on in practice, variation occurs in both surgical and medical management. Perinatal factors that affect preoperative management include the subtype of the syndrome and the patient's birth weight, gestational age, and genetic abnormalities. The general aspects of perioperative stabilization and management are monitoring, use of vasoactive infusions, ventilatory support, and nutrition. Management strategies for balancing single-ventricle physiology are aimed at addressing the 3 major causes of desaturation: diminished pulmonary blood flow, low mixed venous oxygen saturation, and pulmonary venous desaturation.

    2015-03-01

    Percutaneous transcatheter pulmonary valve replacement with the Melody Valve is fast becoming an important adjunct in the treatment of older children and adults with failing right ventricular outflow tract conduits. Recently, the Melody Valve has also been successfully implanted in the tricuspid, mitral, and aortic positions, typically within a failing bioprosthetic valve. We present a patient who underwent Fontan palliation for hypoplastic left heart syndrome variant and subsequently developed severe neoaortic regurgitation, which was successfully treated with a transcatheter neoaortic valve replacement. To our knowledge, this is the first successful use of the Melody Valve in the neoaortic position in a patient with single-ventricle physiology. Successful relief of neoaortic valve regurgitation using replacement with a transcatheter valve may allow avoidance of additional surgery, increase functional longevity of single-ventricle palliation, and postpone the need for orthotopic heart transplantation.

  2. Chronic Pelvic Pain in Women.

    PubMed

    Speer, Linda M; Mushkbar, Saudia; Erbele, Tara

    2016-03-01

    Chronic pelvic pain in women is defined as persistent, noncyclic pain perceived to be in structures related to the pelvis and lasting more than six months. Often no specific etiology can be identified, and it can be conceptualized as a chronic regional pain syndrome or functional somatic pain syndrome. It is typically associated with other functional somatic pain syndromes (e.g., irritable bowel syndrome, nonspecific chronic fatigue syndrome) and mental health disorders (e.g., posttraumatic stress disorder, depression). Diagnosis is based on findings from the history and physical examination. Pelvic ultrasonography is indicated to rule out anatomic abnormalities. Referral for diagnostic evaluation of endometriosis by laparoscopy is usually indicated in severe cases. Curative treatment is elusive, and evidence-based therapies are limited. Patient engagement in a biopsychosocial approach is recommended, with treatment of any identifiable disease process such as endometriosis, interstitial cystitis/painful bladder syndrome, and comorbid depression. Potentially beneficial medications include depot medroxyprogesterone, gabapentin, nonsteroidal anti-inflammatory drugs, and gonadotropin-releasing hormone agonists with add-back hormone therapy. Pelvic floor physical therapy may be helpful. Behavioral therapy is an integral part of treatment. In select cases, neuromodulation of sacral nerves may be appropriate. Hysterectomy may be considered as a last resort if pain seems to be of uterine origin, although significant improvement occurs in only about one-half of cases. Chronic pelvic pain should be managed with a collaborative, patient-centered approach. PMID:26926975

  3. Silent pelvic splenosis: Case report

    PubMed Central

    Lai, Tingmin; Meng, Chunfeng

    2015-01-01

    Introduction Splenosis is a benign, usually asymptomatic, condition involving autotransplantation of splenic tissue that occurs frequently after splenic rupture caused by trauma or surgery [1]. Up to 67% of the patients presenting splenic rupture may develop splenosis [2]. The interval of time between the initial trauma and the diagnosis varies from 3 to 45 years with an average interval of 21 years [3]. Since the finding of this entity is usually accidental, the real incidence is not well known. Although splenosis following traumatic splenectomy after traffic accidents is well-documented in the literature, there do not seem to be many reported cases where splenosis produced gynecological complications [4]. There were fewer than 100 cases of splenosis reported since the first report of Buchbinder and Lipkoff in 1939 [5] in the English language medical literature of which only a minority appeared in the gynecological literature. Presentation of case A case of pelvic and omentum majus splenosis in a patient is presented. Discussion Pelvic splenosis remains a rare finding in clinical practice. In most reported cases in the literature, the diagnosis was not considered before surgery. This approach may obviate the need for invasive evaluation for a primary or secondary neoplasm, and thus unnecessary surgery, and therefore preserve probable functional splenic tissue. Our case was diagnosed using non-surgical modalities. Conclusion Our case emphasizes the rare diagnosing of pelvic splenosis in the evaluating pelvic mass with the tissue evidence instead of surgery.

    Survivors who have received pelvic radiotherapy make up many of the long-term cancer population, with therapies for gynaecological, bowel, bladder and prostate malignancies. Individuals who receive radiotherapy to the pelvis as part of their cancer treatment are at risk of insufficiency fractures. Symptoms of insufficiency fractures include pelvic and back pain and immobility, which can affect substantially quality of life. This constellation of symptoms can occur within 2 months of radiotherapy up to 63 months post-treatment, with a median incidence of 6-20 months. As a condition it is under reported and evidence is poor as to the contributing risk factors, causation and best management to improve the patient's bone health and mobility. As radiotherapy advances, chronic symptoms, such as insufficiency fractures, as a consequence of treatment need to be better understood and reviewed. This overview explores the current evidence for the effect of radiotherapy on bone health and insufficiency fractures and identifies what we know and where gaps in our knowledge lie. The overview concludes with the need to take seriously complaints of pelvic pain from patients after pelvic radiotherapy and to investigate and manage these symptoms more effectively. There is a clear need for definitive research in this field to provide the evidence-based guidance much needed in practice. PMID:26276560

  5. Vaginal childbirth and pelvic floor disorders

    2013-01-01

    Childbirth is an important event in a woman’s life. Vaginal childbirth is the most common mode of delivery and it has been associated with increased incidence of pelvic floor disorders later in life. In this article, the authors review and summarize current literature associating pelvic floor disorders with vaginal childbirth. Stress urinary incontinence and pelvic organ prolapse are strongly associated with vaginal childbirth and parity. The exact mechanism of injury associating vaginal delivery with pelvic floor disorders is not known, but is likely multifactorial, potentially including mechanical and neurovascular injury to the pelvic floor. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist in clusters; hence, the isolated effect of these variables on the pelvic floor is difficult to study. PMID:23638782

    Acute pelvic pain may be the manifestation of various gynecologic and non-gynecologic disorders from less alarming rupture of the follicular cyst to life threatening conditions such as rupture of ectopic pregnancy or perforation of inflamed appendix. In order to construct an algorithm for differential diagnosis we divide acute pelvic pain into gynecologic and non-gynecologic etiology, which is than subdivided into gastrointestinal and urinary causes. Appendicitis is the most common surgical emergency and should always be considered in differential diagnosis if appendix has not been removed. Apart of clinical examination and laboratory tests, an ultrasound examination is sensitive up to 90% and specific up to 95% if graded compression technique is used. Still it is user-depended and requires considerable experience in order to perform it reliably. Meckel's diverticulitis, acute terminal ileitis, mesenteric lymphadenitis and functional bowel disease are conditions that should be differentiated from other causes of low abdominal pain by clinical presentation, laboratory and imaging tests. Dilatation of renal pelvis and ureter are typical signs of obstructive uropathy and may be efficiently detected by ultrasound. Additional thinning of renal parenchyma suggests long-term obstructive uropathy. Ruptured ectopic pregnancy, salpingitis and hemorrhagic ovarian cysts are three most commonly diagnosed gynecologic conditions presenting as an acute abdomen. Degenerating leiomyomas and adnexal torsion occur less frequently. For better systematization, gynecologic causes of acute pelvic pain could be divided into conditions with negative pregnancy test and conditions with positive pregnancy test. Pelvic inflammatory disease may be ultrasonically presented with numerous signs such as thickening of the tubal wall, incomplete septa within the dilated tube, demonstration of hyperechoic mural nodules, free fluid in the "cul-de-sac" etc. Color Doppler ultrasound contributes to more accurate diagnosis of this entity since it enables differentiation between acute and chronic stages based on analysis of the vascular resistance. Hemorrhagic ovarian cysts may be presented by variety of ultrasound findings since intracystic echoes depend upon the quality and quantity of the blood clots. Color Doppler investigation demonstrates moderate to low vascular resistance typical of luteal flow. Leiomyomas undergoing degenerative changes are another cause of acute pelvic pain commonly present in patients of reproductive age. Color flow detects regularly separated vessels at the periphery of the leiomyoma, which exhibit moderate vascular resistance. Although the classic symptom of endometriosis is chronic pelvic pain, in some patients acute pelvic pain does occur. Most of these patients demonstrate an endometrioma or "chocolate" cyst containing diffuse carpet-like echoes. Sometimes, solid components may indicate even ovarian malignancy, but if color Doppler ultrasound is applied it is less likely to obtain false positive results. One should be aware that pericystic and/or hillar type of ovarian endometrioma vascularization facilitate correct recognition of this entity. Pelvic congestion syndrome is another condition that can cause an attack of acute pelvic pain. It is usually consequence of dilatation of venous plexuses, arteries or both systems. By switching color Doppler gynecologist can differentiate pelvic congestion syndrome from multilocular cysts, pelvic inflammatory disease or adenomyosis. Ovarian vein thrombosis is a potentially fatal disorder occurring most often in the early postpartal period. Hypercoagulability, infection and stasis are main etiologic factors, and transvaginal color Doppler ultrasound is an excellent diagnostic tool to diagnose it. Acute pelvic pain may occur even in normal intrauterine pregnancy. This may be explained by hormonal changes, rapid growth of the uterus and increased blood flow. Ultrasound is mandatory for distinguishing normal intrauterine pregnancy from threatened or spontaneous abortion, ectopic pregnancy and other complications that may occur in patients with positive pregnancy test. Incomplete abortion is visualized as thickened and irregular endometrial echo with certain amount of intracavitary fluid. If applied, color Doppler ultrasound reveals low vascular resistance signals in richly perfused intracavitary area. Transvaginal sonography has high sensitivity and specificity in visualization of uterine and adnexal signs of ectopic pregnancy. Color Doppler examination may aid in detection of the peritrophoblastic flow. Furthermore, it facilitates detection of ectopic living embryo, tubal ring or unspecific adnexal tumor. Corpus luteum cysts and leiomyomas are another cause of pelvic pain during pregnancy, which can be correctly diagnosed by ultrasound. Detection of uterine dehiscence and rupture in patients with history of prior surgical intervention on uterine wall relies exclusively on correct ultrasound diagnosis. In patients with placental abruption sonographer detects hypoechoic complex representing either retroplacental hematoma, subchorionic hematoma or subamniotic hemorrhage. In closing, ultrasound has already become important and easily available tool which can efficiently recognize patients with possibly threatening conditions of different origins. PMID:12768897

    Hypoplastic left heart complex (HLHC) consists of less severe underdevelopment of the left ventricle without intrinsic left valvular stenosis, i.e., a subset of hypoplastic left heart syndrome (HLHS). HLHC patients may be able to undergo biventricular repair, while HLHS requires single ventricle palliation (or transplant). However, there is no consensus regarding the likelihood of favorable outcomes in neonates with HLHC selected to undergo this surgical approach. This case report describes a neonate with HLHC, co-arctation of the aorta (CoA), and patent ductus arteriosus (PDA) who was initially palliated using bilateral pulmonary artery banding due to unstable ductus-dependent circulation. A postoperative echocardiogram showed newly appearing CoA and progressively narrowing PDA, which resulted in the need for biventricular repair 21 days following the palliation surgery. The patient was discharged on postoperative day 13 without complications and is doing clinically well seven months after surgery. PMID:27064769

    Extracranial stereotactic radiotherapy is booming. The development and spread of dedicated accelerators coupled with efficient methods of repositioning can now allow treatments of mobile lesions with moderate size, with high doses per fraction. Intuitively, except for the prostate, pelvic tumours, often requiring irradiation of regional lymph node drainage, lend little to this type of treatment. However, in some difficult circumstances, such as boost or re-radiation, stereotactic irradiation condition is promising and clinical experiences have already been reported. PMID:24792995

    Introduction Congenital heart defects are the most common abnormalities in neonatal age. Congenital heart defects occur with a frequency of 3-12/1000 births. A special group is constituted by children with hypoplastic left heart syndrome because their treatment is extremely complex, requiring three-stage surgery and the involvement of various specialists. Material and methods We analysed 100 infants with congenital heart defects in the form of hypoplastic left heart syndrome (HLHS). They were compared with a control group of 100 newborns without structural heart defects. The children's parents were asked to fill out a questionnaire consisting of 10 simple questions. It had been constructed in consultation with a psychologist in order not to offend the feelings of the parents affected by the illness of their offspring. Results Congenital heart defects were present in the family medical histories of 16 HLHS children and 11 healthy children (p = 0.4). Genetic disorders were present in the family medical histories of 13 HLHS children and 15 healthy children (p = 0.73). In the HLHS group, the mothers smoked cigarettes or were exposed to tobacco smoke in 32% of cases; in the control group, this proportion amounted to 23% (p = 0.76). Conclusions The study found no relationship between the occurrence of hypoplastic left heart syndrome in children and the parents’ age, the presence of genetic disorders, or heart defects in the family medical histories.

    A 50-year-old male was brought to our emergency department by ambulance with complaints of pain and numbness in both legs. At arrival, purple spots were evident on his neck and face. Examination of the vital sign indicated septic shock. Laboratory data and blood gas analysis revealed disseminated intravascular coagulation, multiple organ failure, and metabolic acidosis. Peripheral blood smears revealed Howell-Jolly bodies, indicating decreased splenic function. A rapid urinary pneumococcal antigen test was also found to be positive. After admission to the intensive care unit, extensive treatment, including polymyxin-B direct hemoperfusion and administration of methylprednisolone and broad spectrum antibiotics was immediately initiated. Despite of our efforts to save his life, the patient died six hours after the arrival. The following day, blood cultures revealed the presence of Streptococcus pneumoniae. An autopsy revealed a hypoplastic spleen and a bilateral adrenal hemorrhage, indicating acute adrenal insufficiency caused by sepsis. Finally, the patient was diagnosed with Waterhouse-Friderichsen syndrome. Although severe infection may be seen in the splenectomized patients, it should be noted that patients with a hypoplastic spleen may have acute severe infections. We, therefore, report a case of Waterhouse-Friderichsen syndrome resulting from an invasive pneumococcal infection in a patient with a hypoplastic spleen. PMID:26942021

    2006-01-01

    Hypoplastic left heart syndrome (HLHS) affects infants and is uniformly fatal without surgical palliation. Post-surgery mortality rates are highly variable and dependent on postoperative management. A data acquisition system was developed for collection of 73 physiologic, laboratory, and nurse-assessed parameters. The acquisition system was designed for the collection on numerous patients. Data records were created at 30s intervals. An expert-validated wellness score was computed for each data record. To efficiently analyze the data, a new metric for assessment of data utility, the combined classification quality measure, was developed. This measure assesses the impact of a feature on classification accuracy without performing computationally expensive cross-validation. The proposed measure can be also used to derive new features that enhance classification accuracy. The knowledge discovery approach allows for instantaneous prediction of interventions for the patient in an intensive care unit. The discovered knowledge can improve care of complex to manage infants by the development of an intelligent bedside advisory system. PMID:16324907

    In many cases congenital heart disease (CHD) is represented by a complex phenotype and an array of several functional and morphological cardiac disorders. These malformations will be briefly summarized in the first part focusing on two severe CHD phenotypes, hypoplastic left heart syndrome (HLHS) and tetralogy of Fallot (TOF). In most cases of CHD the genetic origin remains largely unknown, though the complexity of the clinical picture strongly argues against a dysregulation which can be attributed to a single candidate gene but rather suggests a multifaceted polygenetic origin with elaborate interactions. Consistent with this idea, genome-wide approaches using whole exome sequencing, comparative sequence analysis of multiplex families to identify de novo mutations and global technologies to identify single nucleotide polymorphisms, copy number variants, dysregulation of the transcriptome and epigenetic variations have been conducted to obtain information about genetic alterations and potential predispositions possibly linked to the occurrence of a CHD phenotype. In the second part of this review we will summarize and discuss the available literature on identified genetic alterations linked to TOF and HLHS. PMID:26069455

    We report a case of a 34-year-old lady with past history of asthma and pulmonary tuberculosis, who presented 5 weeks pregnant with acute dyspnea. Her chest X-ray showed left-sided complete lung collapse and concomitant right-sided pneumothorax. The pneumothorax was initially managed conservatively with a chest tube but due to its persistence despite suction, was subsequently changed to a Pneumostat(TM), with which she was later discharged. She had a normal echocardiography (ejection fraction [EF] 67%) at 5 weeks of gestation but developed pulmonary hypertension (EF 55%, pulmonary arterial pressure 40.7 mmHg) as the pregnancy progressed. She delivered a healthy baby at 35 weeks via elective lower section caesarean section with spinal anesthesia. We followed her up postnatally and noted the presence of left-sided pulmonary embolism, hypoplastic left lung, and left pulmonary artery. The management of this complex case involved a multidisciplinary effort between general medical, respiratory, obstetric, and cardiothoracic teams. PMID:26839696

    Disruption or embryologic derailment of the normal bony architecture of the craniovertebral junction (CVJ) may result in symptoms. As studies of the embryology and pathology of hypoplasia of the occipital condyles and third occipital condyles are lacking in the literature, the present review was performed. Standard search engines were accessed and queried for publications regarding hypoplastic occipital condyles and third occipital condyles. The literature supports the notion that occipital condyle hypoplasia and a third occipital condyle are due to malformation or persistence of the proatlas, respectively. The Pax-1 gene is most likely involved in this process. Clinically, condylar hypoplasia may narrow the foramen magnum and lead to lateral medullary compression. Additionally, this maldevelopment can result in transient vertebral artery compression secondary to posterior subluxation of the occiput. Third occipital condyles have been associated with cervical canal stenosis, hypoplasia of the dens, transverse ligament laxity, and atlanto-axial instability causing acute and chronic spinal cord compression. Treatment goals are focused on craniovertebral stability. A better understanding of the embryology and pathology related to CVJ anomalies is useful to the clinician treating patients presenting with these entities. PMID:23338989

    Children with hypoplastic left heart syndrome (HLHS) have an increased prevalence of central nervous system (CNS) abnormalities. The extent to which this problem is due to CNS maldevelopment, prenatal ischemia, postnatal chronic cyanosis and/or multiple exposures to cardiopulmonary bypass is unknown. To better understand the etiology of CNS abnormalities in HLHS, we evaluated 68 neonates with HLHS; in 28 cases, both fetal ultrasound and echocardiogram data were available to assess head size, head growth and aortic valve anatomy (atresia or stenosis). In addition, we evaluated neuropathology in 11 electively aborted HLHS fetuses. The mean head circumference percentile in HLHS neonates was significantly smaller than HLHS fetuses (22 ± 2% vs. 40 ± 4%, p<0.001). A significant decrease in head growth, defined as a 50% reduction in head circumference percentile, was observed in half (14/28) of HLHS fetuses and nearly a quarter (6/28) were already growth restricted (≤10%) at the time of initial evaluation. Brains from HLHS fetuses demonstrated chronic diffuse white matter injury of varying severity. These patterns of prenatal head growth and brain histopathology identify a spectrum of abnormal CNS development and/or injury in HLHS fetuses. PMID:18552707

    Davis, F E

    1986-10-01

    One hundred twenty-eight pelvic fractures were reviewed. Of the 128 patients with pelvic fractures, there were seven deaths. Pelvic fractures associated with the greatest blood loss and complications were those which occurred in crush-type injuries secondary to automobile accidents or other heavy impact injuries. Unless fractures were of a crush-type with massive fractures, the amount of blood loss correlated more closely with the history of injury than it did with the x-ray appearance of pelvic fracture. A single patient in this series had greater than 45 units blood loss and exhibited many of the basic problems encountered when dealing with patients with major pelvic fractures. The case of this patient is reviewed in detail, including component therapy for massive blood loss. The prophylactic use of caval filtration or an umbrella device might be warranted in patients with massive pelvic fractures. PMID:3767141

    Background: Parkinson disease is a neurodegenerative disease that affects gait and postural stability, resulting in an increased risk of falling. The purpose of this study was to estimate mortality associated with demographic factors after hip or pelvic (hip/pelvic) fracture in people with Parkinson disease. A secondary goal was to compare the mortality associated with Parkinson disease to that associated with other common medical conditions in patients with hip/pelvic fracture. Methods: This was a retrospective observational cohort study of 1,980,401 elderly Medicare beneficiaries diagnosed with hip/pelvic fracture from 2000 to 2005 who were identified with use of the Beneficiary Annual Summary File. The race/ethnicity distribution of the sample was white (93.2%), black (3.8%), Hispanic (1.2%), and Asian (0.6%). Individuals with Parkinson disease (131,215) were identified with use of outpatient and carrier claims. Cox proportional hazards models were used to estimate the risk of death associated with demographic and clinical variables and to compare mortality after hip/pelvic fracture between patients with Parkinson disease and those with other medical conditions associated with high mortality after hip/pelvic fracture, after adjustment for race/ethnicity, sex, age, and modified Charlson comorbidity score. Results: Among those with Parkinson disease, women had lower mortality after hip/pelvic fracture than men (adjusted hazard ratio [HR] = 0.63, 95% confidence interval [CI]) = 0.62 to 0.64), after adjustment for covariates. Compared with whites, blacks had a higher (HR = 1.12, 95% CI = 1.09 to 1.16) and Hispanics had a lower (HR = 0.87, 95% CI = 0.81 to 0.95) mortality, after adjustment for covariates. Overall, the adjusted mortality rate after hip/pelvic fracture in individuals with Parkinson disease (HR = 2.41, 95% CI = 2.37 to 2.46) was substantially elevated compared with those without the disease, a finding similar to the increased mortality associated with a diagnosis of dementia (HR = 2.73, 95% CI = 2.68 to 2.79), kidney disease (HR = 2.66, 95% CI = 2.60 to 2.72), and chronic obstructive pulmonary disease (HR = 2.48, 95% CI = 2.43 to 2.53). Conclusions: Mortality after hip/pelvic fracture in Parkinson disease varies according to demographic factors. Mortality after hip/pelvic fracture is substantially increased among those with Parkinson disease. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence. PMID:24553896

    Hypoplastic left heart syndrome (HLHS) is a severe congenital heart defect (CHD) that necessitates staged, single ventricle surgical palliation. An increased frequency of bicuspid aortic valve (BAV) has been observed among relatives. We postulated number of mutant alleles as a molecular basis for variable CHD expression in an extended family comprised of an HLHS proband and four family members who underwent echocardiography and whole-genome sequencing (WGS). Dermal fibroblast-derived induced pluripotent stem cells (iPSC) were procured from the proband-parent trio and bioengineered into cardiomyocytes. Cardiac phenotyping revealed aortic valve atresia and a slit-like left ventricular cavity in the HLHS proband, isolated bicuspid pulmonary valve in his mother, BAV in a maternal 4° relative, and no CHD in his father or sister. Filtering of WGS for rare, functional variants that segregated with CHD and were compound heterozygous in the HLHS proband identified NOTCH1 as the sole candidate gene. An unreported missense mutation (P1964L) in the cytoplasmic domain, segregating with semilunar valve malformation, was maternally inherited and a rare missense mutation (P1256L) in the extracellular domain, clinically silent in the heterozygous state, was paternally inherited. Patient-specific iPSCs exhibited diminished transcript levels of NOTCH1 signaling pathway components, impaired myocardiogenesis, and a higher prevalence of heterogeneous myofilament organization. Extended, phenotypically characterized families enable WGS-derived variant filtering for plausible Mendelian modes of inheritance, a powerful strategy to discover molecular underpinnings of CHD. Identification of compound heterozygous NOTCH1 mutations and iPSC-based functional modeling implicate mutant allele burden and impaired myogenic potential as mechanisms for HLHS. PMID:26164125

    Hypoplastic left heart syndrome (HLHS) is a severe form of congenital heart disease characterized by underdevelopment of the left heart. There has been no previously defined "classic" ECG pattern in a large homogenous population of patients with HLHS. We performed a retrospective review of ECGs from neonates with HLHS from 2001 to 2011 with electrocardiograms available prior to surgical intervention. Eighty-nine neonates met the inclusion criteria and were compared to a control population. HLHS patients had a longer PR interval 108 ± 18 versus 98 ± 11 ms (p < 0.05), a wider QRS complex 84 ± 17 versus 54 ± 5 ms (p < 0.05), lower voltage S waves in V1 2.0 ± 3.3 versus 5.8 ± 4.6 mm (p < 0.001) or absent S waves in V1 52 versus 4 % (p < 0.001) and lower voltage R waves in V6 7.8 ± 4.8 versus 9.3 ± 4.2 mm (p < 0.05). Patients with HLHS were more likely to have absent Q waves in the lateral precordial leads 78 versus 0 % (p < 0.001) and inferior leads 20 versus 1 % (p < 0.001) and an abnormal frontal plane QRS axis 26 versus 11 % (p < 0.05). HLHS patients were more likely to have a preexcited appearance 11 versus 0 % (p = 0.001). Despite these findings, 20 % of patients with HLHS had a normal ECG. Compared to age-matched controls, patients with HLHS were more likely to exhibit a longer PR interval, a wider QRS complex, decreased left-sided forces, an absence of septal Q waves in the inferior and lateral leads, an abnormal frontal plane QRS axis and a preexcited appearance.

    Pelvic malignancies, including bladder, prostate, and gynecologic cancers, are typically treated with some form of radiation therapy. Reducing radiation-related toxicities in these patients is important for maintaining good quality of life as survival rates increase and also for directly affecting cure rates by reducing delays in radiotherapy. Amifostine (Ethyol) has been shown to reduce rectal bleeding in patients with prostate cancer treated with radiation therapy, prevent radiation-related dermatitis, and provide widespread mucosal protection without adversely affecting local or distant tumor control.

    [Purpose] The purpose of this study was to investigate the relationship between pelvic alignment and dysmenorrhea in general women. [Subjects and Methods] One hundred two females participated in this study. They were divided into a dysmenorrhea group and a normal group based on the results of a Visual Analogue Scale (VAS) assessment of pain and the Menstrual Distress Questionnaire (MDQ). The survey data was collecting from 5th July to 20th September, 2014. Formetric 4D was used to measure the pelvic alignment, including the values of Trunk Imbalance, Pelvic Tilt, Surface Rotation, Lateral Deviation, Kyphosis Angle, Lordosis Angle. [Results] There was a difference in the spine alignments of each group. The value of pelvic torsion was 2.4 ± 1.8 degree in those with dysmenorrhea, while it was 1.7 ± 1.1 degree in those without. [Conclusion] In conclusion, the results suggest that there is a relationship between menstrual pain and pelvic torsion. PMID:27134354

  8. FE-Studies of Different Aspects of Shear Localization in Granular Bodies within Micro-Polar Hypoplasticity

    NASA Astrophysics Data System (ADS)

    Tejchman, Jacek

    2009-06-01

    The paper deals with shear localization in granular bodies. The effects of a stochastic distribution of initial void ratio, shear rate and grain crushing were investigated. To describe a mechanical behaviour of a cohesionless granular material, a micro-polar hypoplastic constitutive model was used. It includes particle rotations, curvatures, non-symmetric stresses, couple stresses and the mean grain diameter as a characteristic length. Due to the presence of a characteristic length in the form of a mean grain diameter, the FE results are mesh-independent (load-displacement curves and thickness and spacing of shear zones).

  12. Evaluation of acute pelvic pain in women.

    PubMed

    Kruszka, Paul S; Kruszka, Stephen J

    2010-07-15

    Diagnosis of pelvic pain in women can be challenging because many symptoms and signs are insensitive and nonspecific. As the first priority, urgent life-threatening conditions (e.g., ectopic pregnancy, appendicitis, ruptured ovarian cyst) and fertility-threatening conditions (e.g., pelvic inflammatory disease, ovarian torsion) must be considered. A careful history focusing on pain characteristics, review of systems, and gynecologic, sexual, and social history, in addition to physical examination helps narrow the differential diagnosis. The most common urgent causes of pelvic pain are pelvic inflammatory disease, ruptured ovarian cyst, and appendicitis; however, many other diagnoses in the differential may mimic these conditions, and imaging is often needed. Transvaginal ultrasonography should be the initial imaging test because of its sensitivities across most etiologies and its lack of radiation exposure. A high index of suspicion should be maintained for pelvic inflammatory disease when other etiologies are ruled out, because the presentation is variable and the prevalence is high. Multiple studies have shown that 20 to 50 percent of women presenting with pelvic pain have pelvic inflammatory disease. Adolescents and pregnant and postpartum women require unique considerations.

This process is critical for reconstructive pelvic surgeries, particularly with the advent of vaginal mesh procedures. In this article, we review the principles of informed consent, the pros and cons of different approaches in reconstructive pelvic surgery, the current legal issues surrounding mesh use for vaginal surgery, and tips on how to incorporate this information when consenting patients for pelvic floor surgery.

    Pixie ear deformity is a condition in which the inferior edge of the helix of the ear is attached to the cheek without a convolutional notch at the ear lobule-cheek junction. Numerous surgical techniques have been proposed to correct pixie earlobe deformities. However, several of these techniques result in anterior or inferior scars of the ear lobules or dog-ear deformities. Such visible scarring detracts from the esthetics of the ear lobule.We report a novel method for the correction of pixie ear deformities in patients with small ear lobules. A hypoplastic ear lobule was expanded by a V-Y advancement flap designed on the posterior aspect of the ear lobule, and a dermofat graft was placed in the subcutaneous layer under the advanced flap. As a result, the pixie ear lobe deformity was camouflaged by the expanded ear lobule. Moreover, no scars appeared on the anterior or inferior sides of the ear lobule, and a natural appearance of the ear lobe was achieved.We conclude that this method is a feasible alternative surgical option for hypoplastic pixie ear lobe deformities to avoid visible scarring in the anterior or inferior aspects of the ear lobe.

    This study aims to evaluate the biomechanical mechanism of pelvic ring injury for the stability of pelvis using the finite element (FE) method. Complex pelvic fracture (i.e., anterior column with posterior hemitransverse lesion) combined with pelvic ramus fracture was used to evaluate the biomechanics stability of the pelvis. Three FE fracture models (i.e., Dynamic Anterior Plate-Screw System for Quadrilateral Area (DAPSQ) for complex pelvic fracture with intact pubic ramus, DAPSQ for complex pelvic fracture with pubic ramus fracture, and DAPSQ for complex pelvic fracture with fixed pubic ramus fracture) were established to explore the biomechanics stability of the pelvis. The pubic ramus fracture leads to an unsymmetrical situation and an unstable situation of the pelvis. The fixed pubic ramus fracture did well in reducing the stress levels of the pelvic bone and fixation system, as well as displacement difference in the pubic symphysis, and it could change the unstable situation back to a certain extent. The pelvic ring integrity was the prerequisite of the pelvic stability and should be in a stable condition when the complex fracture is treated. PMID:26495033

  16. Dysplastic kidneys.

    2008-06-01

    Dysplastic kidneys are common malformations affecting up to 1 in 1000 of the general population. They are part of the spectrum of Congenital Abnormalities of the Kidney and Urinary Tract (CAKUT) and an increasing number of children are being diagnosed on antenatal ultrasound. In the past, these patients may not have been detected until adulthood following investigation for other illness, or even as incidental findings at post mortem, unless there was severe bilateral dysplasia leading to Potter's sequence or renal failure in childhood. Excluding syndromic cases with defects in other organ systems, features linked to worse prognosis at presentation are: (1) bilateral disease; (2) decreased functional renal mass (which encompasses not just small kidneys but also large ones where cysts replace normal architecture); (3) lower urinary tract obstruction; and (4) anhydramnios or severe oligohydramnios. Dysplasia and renal function are dynamic and can evolve during pregnancy, so repeated assessment is necessary when pathology is expected. Worsening dimensions or decreasing amniotic fluid levels imply poorer prognosis, but there are no proven therapies during pregnancy, though vesicoamniotic shunting may be indicated with obstruction. Postnatal investigations aim to define the anatomy, which helps to estimate risks of infection and kidney function. Management might then involve observation, prophylactic antibiotics, surgery and/or renal support. Risks of renal malignancy and hypertension are low during childhood, but longer-term follow-up is needed, particularly to determine blood pressure and renal function in adulthood and pregnancy. Around 10% of cases have a family history of significant renal/urinary tract malformation. Monogenic causes include mutations in individual genes, such as TCF2/hepatocyte nuclear factor 1ss (HNF1beta), PAX2 and uroplakins, but there are also recent reports of children with compound heterozygote mutations in several renal/urinary tract developmental genes. Effective genetic screening in future may require gene chip or other techniques to assess multiple genes concurrently, but this should not replace a multidisciplinary approach to these often difficult cases.

    Pelvic congestion syndrome (PCS) presents with a non-cyclic pelvic pain lasting more than six months in duration in premenopausal women. Pelvic ultrasonography or computed tomography is usually the first imaging modality used to evaluate patients with suspected PCS. PCS is confirmed by visible congestion of the pelvic veins on selective ovarian venography. To our knowledge, the role of endoscopic ultrasonography (EUS) has not been reported. EUS showed multiple dilated structures especially on left side around the uterus and ovaries, which are compatible with other radiological investigations of PCS Although PCS is not typical areas within the scope of practice of endosonographers, it is useful to be familiar with the findings. We report a case of PCS that was diagnosed with the aid of EUS. PMID:24618909

    The development of surgical site infection (SSI) remains the most common complication of gynecologic surgical procedures and results in significant patient morbidity. Gynecologic procedures pose a unique challenge in that potential pathogenic microorganisms from the skin or vagina and endocervix may migrate to operative sites and can result in vaginal cuff cellulitis, pelvic cellulitis, and pelvic abscesses. Multiple host and surgical risk factors have been identified as risks that increase infectious sequelae after pelvic surgery. This paper will review these risk factors as many are modifiable and care should be taken to address such factors in order to decrease the chance of infection. We will also review the definitions, microbiology, pathogenesis, diagnosis, and management of pelvic SSIs after gynecologic surgery. PMID:25788822

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a debilitating condition, traditionally treated with antimicrobials, nonsteroidal anti-inflammatory drugs, and alpha-blockers. Pelvic floor tension myalgia is hypothesized to be a contributing factor in CPPS. Biofeedback training for CPPS is based on the principle that maximum muscle contraction prompts maximum muscle relaxation. Similar chronic pain conditions have been treated successfully with biofeedback-assisted techniques of neuromuscular reeducation. Preliminary study by our group has shown biofeedback, pelvic floor reeducation, and bladder training to be helpful in the treatment of CP/CPPS. Overall, 8 of 11 patients had improvement in either pain scores or their chronic prostatitis pain index scores. With no cure for CP/CPPS available, biofeedback and pelvic floor reeducation merit further evaluation in the treatment of this condition. PMID:12521595

    Postoperative pelvic pain after gynecological surgery is a readily detected but unspecific sign of complication. Imaging as a complement to physical examination helps establish the etiological diagnosis. In the context of emergency surgery, vascular, urinary and digestive injuries constitute the most frequent intraoperative complications. During the follow-up of patients who had undergone pelvic surgery, imaging should be performed to detect recurrent disease, postoperative fibrosis, adhesions and more specific complications related to prosthetic material. Current guidelines recommend using pelvic ultrasonography as the first line imaging modality whereas the use of pelvic computed tomography and/or magnetic resonance imaging should be restricted to specific situations, depending on local availability of equipment and suspected disease.

    Pelvic organ prolapse (POP) is a serious health issue affecting many adult women. Complications of POP include pelvic pressure, pelvic pain, and problems in emptying their bowels or bladder. Sometimes, POP may even cause urinary outflow obstruction and lead to bladder or kidney infections. Currently, synthetic and naturally derived materials have been chosen for treatment of POP to reduce the high recurrence rates after surgical interventions. However, existing materials for POP treatment cannot meet the clinical requirements in terms of biocompatibility, mechanics, and minimal risk of rejection. Especially, erosion in synthetic polymers and rapid degradation in natural polymers limit their further applications in clinics. To address these concerns, we report a novel POP replacement using core–sheath polystyrene/gelatin electrospun nanofiber mesh. The outside gelatin sheath provides a hydrophilic surface and implantable integrity between host and guest, while the inner PS core offers the necessary mechanical support. The composite mesh shows graft accommodation in pelvic submucosa after implantation in vivo, as shown in hematoxylin–eosin staining and T helper cell phenotype and macrophage phenotype stainings. Qualitative analysis of inducible nitric oxide synthase, arginase, interferon-γ, and interleukin-10 gene expressions also indicates that the implanted composite mesh switches to accommodation mode 2 weeks postimplantation. Thus, these novel core–sheath polystyrene/gelatin nanofibrous membranes are promising in pelvic reconstruction. PMID:25995629

  6. Pelvic incidence: a fundamental pelvic parameter for three-dimensional regulation of spinal sagittal curves.

    1998-01-01

    This paper proposes an anatomical parameter, the pelvic incidence, as the key factor for managing the spinal balance. Pelvic and spinal sagittal parameters were investigated for normal and scoliotic adult subjects. The relation between pelvic orientation, and spinal sagittal balance was examined by statistical analysis. A close relationship was observed, for both normal and scoliotic subjects, between the anatomical parameter of pelvic incidence and the sacral slope, which strongly determines lumbar lordosis. Taking into account the Cobb angle and the apical vertebral rotation confers a three-dimensional aspect to this chain of relations between pelvis and spine. A predictive equation of lordosis is postulated. The pelvic incidence appears to be the main axis of the sagittal balance of the spine. It controls spinal curves in accordance with the adaptability of the other parameters. PMID:9629932

    Although primarily used for treatment of stress incontinence, pelvic floor rehabilitation has been reported to have some value in the treatment of detrusor instability and urgency. In neurogenic bladder dysfunction due to Multiple Sclerosis, many authors have suggested the possible use of pelvic floor rehabilitation as a treatment modality. Therefore, we designed an open prospective trial to look at the possible role of pelvic floor rehabilitation in voiding dysfunction due to MS, concentrating upon the clinical and neurological parameters in relation to the outcome. A new scoring system for pelvic floor dysfunction is introduced. Thirty female patients were evaluated. In 25, the strength of the pelvic floor was significantly improved after one month (p < 0.001). In all patients but one the endurance score improved significantly (p < 0.001) as did the exhaustibility score (p = 0.01). The relaxation score on the other hand did not show any significant evolution despite intensive training. Cystometric findings after one month did not significantly differ from the initial cystometric findings. There was a significant increase in the mean functional bladder capacity as read from the voiding charts from 173.8 cc +/- 53.9 cc to 208.5 cc +/- 57.6 cc (p = 0.005). Also the mean urinary frequency decreased significantly from 12.7 +/- 3.6 to 9.1 +/- 2.6 (p < 0.01) as did the mean number of daily incontinent episodes from 2.8 +/- 1.3 to 1.5 +/- 1.5 (p < 0.01). Pelvic floor rehabiltation has a place in the treatment of MS patients with a low Kurtzke score and without pelvic floor spasticity. PMID:10218095

    Male salamanders use nephrons from the genital kidney to transport sperm from the testicular lobules to the Wolffian duct. The microstructure of the epithelia of the genital kidney proximal tubule and distal tubule was studied over 1 year in a population of Notophthalmus viridescens from Crawford and Pike counties in central Missouri. Through ultrastructural analysis, we were able to support the hypothesis that the genital kidney nephrons are modified to aid in the transportation of sperm. A lack of folding of the basal plasma membrane, in both the genital kidney proximal and distal tubules when compared to the pelvic kidney proximal and distal tubules, reduces the surface area and thus likely decreases the efficiency of reabsorption in these nephron regions of the genital kidney. Ciliated epithelial cells are also present along the entire length of the genital kidney proximal tubule, but are lacking in the epithelium of the pelvic kidney proximal tubule. The exact function of these cilia remains unknown, but they may aid in mixing of seminal fluids or the transportation of immature sperm through the genital kidney nephrons. Ultrastructural analysis of proximal and distal tubules of the genital kidney revealed no seasonal variation in cellular activity and no mass production of seminal fluids throughout the reproductive cycle. Thus, we failed to support the hypothesis that the cellular activity of the epithelia lining the genital kidney nephrons is correlated to specific events in the reproductive cycle. The cytoplasmic contents and overall structure of the genital and pelvic kidney epithelial cells were similar to recent observations in Ambystoma maculatum, with the absence of abundant dense bodies apically in the epithelial cells lining the genital kidney distal tubule.

    A hybrid procedure combining bilateral pulmonary artery banding with ductal stenting has recently been used as stage I palliation for hypoplastic left heart syndrome. However, the advantage of the hybrid procedure over the Norwood procedure on ventricular energetics remains unclear. To clarify this, we performed a computational analysis with a combination of time-varying elastance chamber model and modified three-element Windkessel vascular model. Although mean pulmonary artery (PA) pressure, pulmonary flow, and oxygen saturation were almost equivalent with the Norwood procedure, the hybrid procedure delivered higher systolic and lower diastolic systemic arterial pressures compared to the Norwood procedure with right ventricle (RV) to PA shunt. As a result, the hybrid procedure yielded increased systolic pressure-volume area and impaired mechanical efficiency. Therefore, the hybrid procedure has probably no advantage on ventricular energetics compared to the Norwood procedure with a RV-PA shunt. PMID:25432766

    Valvular competency of the foramen ovale (patent foramen ovale) is regarded as a common finding in the neonatal foal and usually occurs in isolation. True atrial septal defects appear to be uncommon and are usually associated with other congenital cardiac lesions. The present report describes a case of atrial septal defect type 1 (persistent ostium primum) complicated by hypoplastic right ventricle, and tricuspid dysplasia, in a Welsh Mountain pony foal, and discusses the embryogenesis of the abnormality. A critical review of the literature suggests that atrial septal defects may occur more frequently than they are reported, and that on occasion they may be described erroneously as patent foramen ovale. The clinical significance of uncomplicated discontinuity of the atrial septum is slight, depending upon the size and location of the defect. Complicated atrial septal defects vary in clinical significance according to the nature of the associated defects. Images Fig. 1. Fig. 2. Fig. 3. Fig. 4. PMID:4075243

    An unusual familial case of three sibs with a partial duplication of distal Xp sequences is described. The proband, an 18 year old boy, showed mental retardation, severe dysmorphic features, hypogonadotrophic hypogonadism (HHG), and hypoplastic external genitalia. His karyotype was 46,Y,inv dup(X) (p22.11-->p 22.32). The proband has two sisters each with the same inv dup(Xp) chromosome. Both sisters presented with short stature but were otherwise phenotypically normal. The abnormal X chromosome was inactive in the majority of cells examined. Southern blot dosage analysis indicated a duplication of distal Xp sequences. The proximal breakpoint is located between DXS28 and DXS41, and is therefore at least 2 Mb distal to the DSS locus. The relationship between the phenotype and the Xp duplication is discussed. Images PMID:8880579

    First stage palliation of hypoplastic left heart syndrome, i.e., the Norwood operation, results in a complex physiological arrangement, involving different shunting options (modified Blalock-Taussig, RV-PA conduit, central shunt from the ascending aorta) and enlargement of the hypoplastic ascending aorta. Engineering techniques, both computational and experimental, can aid in the understanding of the Norwood physiology and their correct implementation can potentially lead to refinement of the decision-making process, by means of patient-specific simulations. This paper presents some of the available tools that can corroborate clinical evidence by providing detailed insight into the fluid dynamics of the Norwood circulation as well as alternative surgical scenarios (i.e., virtual surgery). Patient-specific anatomies can be manufactured by means of rapid prototyping and such models can be inserted in experimental set-ups (mock circulatory loops) that can provide a valuable source of validation data as well as hydrodynamic information. Such models can be tuned to respond to differing the patient physiologies. Experimental set-ups can also be compatible with visualization techniques, like particle image velocimetry and cardiovascular magnetic resonance, further adding to the knowledge of the local fluid dynamics. Multi-scale computational models include detailed three-dimensional (3D) anatomical information coupled to a lumped parameter network representing the remainder of the circulation. These models output both overall hemodynamic parameters while also enabling to investigate the local fluid dynamics of the aortic arch or the shunt. As an alternative, pure lumped parameter models can also be employed to model Stage 1 palliation, taking advantage of a much lower computational cost, albeit missing the 3D anatomical component. Finally, analytical techniques, such as wave intensity analysis, can be employed to study the Norwood physiology, providing a mechanistic perspective on the ventriculo-arterial coupling for this specific surgical scenario.

    2009-04-01

    PURPOSE OF THE STUDY Surgery for the nonunion or malunion of pelvic fractures is not common even at specialised departments. This article presents the authors experience with this procedure, completed with case studies and a review of relevant literature. MATERIAL AND METHODS From 1998 to 2007, a total of 359 patients underwent surgery for pelvic trauma. In the same period, eight surgeries on nonunions or malunions of the pelvis were performed, three in men and five in women. The average age of the patients was 37.3 years (range from 15 to 68). The primary treatment included conservative therapy (two patients), external fixation (three patients) and osteosynthesis of the anterior pelvic segment in another three patients. Reconstructive surgeries were always executed for nonunion or malunion or for both conditions together. Patients suffered most often from pain, limping, from the need of using crutches or leg shortening; no diffuculties occurred while sitting. Surgery for nonunion or malunion was performed at the average period of 29.3 months (range from 6 to 84) after injury. Surgical techniques and risks are described in detail. RESULTS Two patients suffer from persistent pain after surgery. In one patient, it is due to partial sacroiliac ankylosis with pathological mobility of the remaining part of the sacroiliac joint together with nonunion of the fractured dorsal part of the ilium. In the other one, pain comes from muscular dysbalance, as well as from chronic lesions in the sacroiliac joint and from scoliosis, despite the fact that the pelvis was successfully reconstructed 7 years after the initial injury. Four patients have no or only transient pain. In four patients limping disappeared after surgery; in two it is still persisting. One of these is the patient with partial sacroiliac joint ankylosis, while symphysis pubic diasthesis persists in the other. Leg length difference, sitting problems or other complaints following surgery are not observed. Four patients developed union detected radiologically, widening of the symphysis persists in one patient and sacroiliac joint problem in another one. Excellent results with anatomic integrity in all three x-ray projections were achieved in only two patients. Satisfactory outcome with a residual deformity of less than 1 cm of the vertical or posterior displacement or up to 15-degree rotation in any plane was achieved in three patients. A poor outcome involving more than 1-cm dislocation was found in one case. DISCUSION The most common cause of poorly healed pelvic fractures is a misdiagnosis of the primary injury and a subsequent conservative way of treatment. Injuries to the posterior pelvic segment are repeatedly underestimated. A frequent error in pelvic ring fracture therapy is that only the anterior pelvic segment is treated surgically, often with only a simple external fixator inserted in the iliac crests. In addition, the treatment strategy is often decided on in hospitals whose surgeons have not enough in pelvic trauma surgery. The most frequent complaints associated with an inadequate treatment are pain, walking problems and limping. Sitting can be difficult in some patients. Urinary bladder can be compressed with the result of frequent and urgent miction, and vaginal compression could bring about dyspareunia. Additionally, pelvic deformations in women can aggravate delivery. Cosmetic changes due to a prominent sacrum, a prominent greater trochanter or distal spine scoliosis are also of concern. The method of an accurate measurement of anatomic alterations of the pelvis is presented. CONCLUSIONS Early surgery of the pelvic trauma enables an adequate restoration of pelvic anatomy and provides conditions for good and reliable stability of both the posterior and anterior pelvic segments. Late repairs of nonunions or malunions are demanding and associated with a high risk of serious complications, often with long-term sequelae. Key words: pelvic fracture, malunion, nonunion.

  3. Physical activity and the pelvic floor.

    Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However, future research is needed to fill the many gaps in our knowledge. Prospective studies are needed in all populations, including potentially vulnerable women, such as those with high genetic risk, levator ani muscle injury, or asymptomatic pelvic organ prolapse, and on women during potentially vulnerable life periods, such as the early postpartum or postoperative periods.

    A major challenge in understanding the origin of terrestrial vertebrates has been knowledge of the pelvis and hind appendage of their closest fish relatives. The pelvic girdle and appendage of tetrapods is dramatically larger and more robust than that of fish and contains a number of structures that provide greater musculoskeletal support for posture and locomotion. The discovery of pelvic material of the finned elpistostegalian, Tiktaalik roseae, bridges some of these differences. Multiple isolated pelves have been recovered, each of which has been prepared in three dimensions. Likewise, a complete pelvis and partial pelvic fin have been recovered in association with the type specimen. The pelves of Tiktaalik are paired and have broad iliac processes, flat and elongate pubes, and acetabulae that form a deep socket rimmed by a robust lip of bone. The pelvis is greatly enlarged relative to other finned tetrapodomorphs. Despite the enlargement and robusticity of the pelvis of Tiktaalik, it retains primitive features such as the lack of both an attachment for the sacral rib and an ischium. The pelvic fin of Tiktaalik (NUFV 108) is represented by fin rays and three endochondral elements: other elements are not preserved. The mosaic of primitive and derived features in Tiktaalik reveals that the enhancement of the pelvic appendage of tetrapods and, indeed, a trend toward hind limb-based propulsion have antecedents in the fins of their closest relatives.

  5. Pelvic Incidence: The Great Biomechanical Effort.

    Medical textbooks present the pelvis and the spine as distinct entities-an unfortunate practice that does not reflect the crucial and critical role that the pelvis plays in regulating spino-pelvic alignment. Researchers are working to delineate this role. Dubousset proposed the concept of the 3-dimensional pelvic vertebra, which suggested that the pelvis is just another caudal vertebra of the spine, and that analysis of the spine requires simultaneous analysis of pelvic morphology. To quantify pelvic morphology, Legaye introduced the pelvic incidence angle (PI) and espoused the theory that this angle regulates sagittal curvature of the spine. The PI is formed from 2 lines: line 1, perpendicular to the sacrum from the midline of the sacral plate, aims to quantify spatial orientation and dictate the lumbar curve; line 2, extending from the midline of the sacrum to the midpoint between femoral heads, illustrates the importance of sacral position inside the pelvis (SDC Figure 1, http://links.lww.com/BRS/B99).

    Objective To review paediatric posterior urethral injuries and the current potential management options; because urethral injury due to pelvic fracture in children is rare and has a low incidence, the management of this type of trauma and its complications remains controversial. Methods We reviewed previous reports identified by searching the PubMed Medline electronic database for clinically relevant articles published in the past 25years. The search was limited to the keywords pediatric, pelvic fracture, urethral injury, stricture, trauma and reconstruction. Results Most paediatric urethral injuries are a result of pelvic fractures after high-impact blunt trauma. After the diagnosis, immediate bladder drainage via a suprapubic cystotomy, or urethral realignment, are the initial management options, except for a possible immediate primary repair in girls. The common complications of pelvic fracture-associated urethral injury include urethral stricture formation, incontinence and erectile dysfunction. Excellent results can be achieved with delayed urethroplasty for pelvic fracture-associated urethral injuries. Conclusion Traumatic injury to the paediatric urethra is rare and calls for an immediate diagnosis and management. These devastating injuries have a high complication rate and therefore a close follow-up is warranted to assure adequate delayed repair by a reconstructive urologist. PMID:26019977

  7. The Surgical Treatment of Pelvic Bone Metastases

    2015-01-01

    Pelvic bone metastases are a growing concern in the field of orthopedic surgery. Patients with pelvic metastasis are individually different with different needs of treatment in order to attain the best possible quality of life despite the advanced stage of disease. A holistic collaboration among the oncologist, radiation therapist, and orthopedic surgeon is mandatory. Special attention has to be directed to osteolytic lesions in the periacetabular region as they can provoke pathological fractures and subsequent functional impairment. Different reconstruction techniques for the pelvis are available; the choice depends on the patient's prognosis, size of the bone defect, and response of the tumor to adjuvant treatment. If all the conservative treatments are exhausted and the patient is not eligible for surgery, one of the various percutaneous ablation procedures can be considered. We propose a pelvic analogue to the treatment algorithm in long bone metastasis and a scoring system in pelvic metastasis. This algorithm aims to simplify the teamwork and to avoid under- or overtreatment of pelvic bone metastases. PMID:25810925

  9. Restoring pelvic floor function in men: review of RCTs.

    PubMed

    Dorey, Grace

    The male pelvic floor muscles support the abdominal contents, are active during breathing, maintain urinary and faecal continence, increase local blood supply and are active during sexual intercourse. It was hypothesized that weak pelvic floor muscles would compromise these functions in men and lead to urinary and faecal incontinence and sexual dysfunction and that pelvic floor muscle strengthening would restore normal function. After a literature search of randomized controlled trials was undertaken, it was found that weak pelvic floor muscles compromised normal pelvic floor function and led to urinary incontinence and erectile dysfunction. Strengthening the pelvic floor muscles was shown to significantly improve post-prostatectomy urinary continence, post-micturition dribble and erectile function. It would be prudent for all men to exercise their pelvic floor muscles to maintain normal pelvic floor function. PMID:16301945

    Pelvic organ prolapse is a highly prevalent condition in the female population, which impairs the health-related quality of life of affected individuals. Despite the lack of robust evidence, selective modification of obstetric events or other risk factors could play a central role in the prevention of prolapse. While the value of pelvic floor muscle training as a preventive treatment remains uncertain, it has an essential role in the conservative management of prolapse. Surgical trends are currently changing due to the controversial issues surrounding the use of mesh and the increasing demand for uterine preservation. The evolution of laparoscopic and robotic surgery has increased the use of these techniques in pelvic floor surgery. PMID:25343034

    2003-06-01

    Actinomycosis is a chronic inflammatory disease rarely observed in the pelvic form but rather frequently in the cervicofacial tract. The pelviabdominal form is difficult to diagnose because of its various clinical presentations that can lead to misdiagnosis by imitating a neoblastic disease, a bowel inflammatory disease, an acute diverticulitis or gynecological disorders. The case is reported of a 43 year old woman with prolonged use of an intrauterine contraceptive device and with severe phlogosis secondary to extensive pelvic actinomycosis involving both ovaries, the urinary duct and the rectosigmoid, misdiagnosed as pelvic frostbite presentation of a malignant neoplasm. A bilateral hysterosalpingo-oophorectomy surgery was performed and a urethral stent was placed before the operation. Rarely, has the pelvis been so heavily involved by a chronic actinomycosis infection. PMID:12955069

    The accuracy of dose delivered to the pelvis in patients undergoing radiation therapy for various pelvic malignancies was checked by the placement of thermoluminescent dosimeters (TLD) in either the rectum or the vagina. The probes were left in place for an entire treatment. Eighty-two measurements in 37 patients were evaluated. The ratio of the TLD measured dose to the calculated dose, D/sub TLD//D/sub calc/, was obtained for each measurement. A perfect match would give a ratio of 1.000. The average dose ratio for the measurements was 1.012, indicating an average accuracy of within 2%. No correlation could be shown between the dose radio and obesity or quantity of pelvic bowel gas. We conclude that pelvic irradiation can be delivered with good precision, and that TLD's are useful in monitoring treatment dose.

    Abstract As pelvic fractures in children and adolescents are very rare, the surgical management is not well delineated nor are the postoperative complications. The aim of this study using the prospective data from German Pelvic Trauma Registry study was to evaluate the various treatment approaches compared to adults and delineated the differences in postoperative complications after pelvic injuries. Using the prospective pelvic trauma registry established by the German Society of Traumatology and the German Section of the Arbeitsgemeinschaft für Osteosynthesefragen (AO), International in 1991, patients with pelvic fractures over a 12-year time frame submitted by any 1 of the 23 member level I trauma centers were reviewed. We identified a total of 13,525 patients including pelvic fractures in 13,317 adults and 208 children aged ≤14 years and compared these 2 groups. The 2 groups’ Injury Severitiy Score (ISS) did not differ statistically. Lethality in the pediatric group was 6.3%, not statistically different from the adults’ 4.6%. In all, 18.3% of the pediatric pelvic fractures were treated surgically as compared to 22.7% in the adult group. No child suffered any thrombosis/embolism, acute respiratory distress syndrome (ARDS), multiorgan failure (MOF), or neurologic deficit, nor was any septic MOF detected. The differences between adults and children were statistically significant in that the children suffered less frequently from thrombosis/embolism (P = 0.041) and ARDS and MOF (P = 0.006). This prospective multicenter study addressing patients with pelvic fractures reveals that the risk for a thrombosis/embolism, ARDS, and MOF is significant lower in pediatric patients than in adults. No statistical differences could be found in the ratios of operative therapy of the pelvic fractures in children compared to adults. PMID:26705223

    Acute pelvic pain in women is a routine situation in any emergency unit. The radiologist should know how to explore the patient with regards to the history and clinical findings. Ultrasonography is the primary and sometimes the only necessary imaging tool in the assessment of acute pelvic pain in women. MRI is the preferred technique in pregnant or young women. CT is more valuable for assessing nongynecologic disorders or post-partum and post-operative infections. This article reviews the contribution of each imaging technique in this clinical situation. Emphasis is put on the importance of age and clinical findings in the diagnostic strategy. PMID:18288036

    Prostate cancer is the most common cancer in men in the UK. Treatment with radical prostatectomy may produce risk factors that commonly include urinary incontinence and erectile dysfunction. Post-prostatectomy incontinence can be classified as either stress urinary incontinence, urge urinary incontinence or post-micturition dribble. Evidence has shown that these embarrassing conditions may be treated successfully with pre-operative and post-operative pelvic floor exercises, which include 'the knack', urge suppression, fluid advice and a post-void contraction for post-micturition dribble. New evidence suggests that men with erectile dysfunction may benefit from the same pelvic floor exercises. PMID:23752574

    Pelvic floor muscles (PFM) are the layer of muscles that support the pelvic organs and span the bottom of the pelvis. Weakened PFM mean the internal organs are not fully supported and can lead to difficulties controlling the release of urine, faeces or flatus. Pregnancy and vaginal birth are a recognised cause of PFM weakness; however it has been shown that PFM exercises, if carried out correctly and routinely, can reduce the severity of symptoms. Midwives need to be pro-active in teaching PFM exercises and identifying women who may need to be referred on for more specialist treatment. PMID:25109068

    As the surgical correction of pelvic organ prolapse has continued to evolve, robotic-assisted abdominal sacrocolpopexy (RASC) has gained increasing popularity. Studies have shown equivalent subjective and objective outcomes compared with the "gold standard" abdominal sacrocolpopexy. Additionally, this approach is associated with a shorter hospital stay and less cost than the traditional open procedure. Although there is a learning curve associated with RASC, the basic principles of the procedure are the same. Herein, we discuss the robotic techniques for repair of pelvic organ prolapse as well as discuss the currently available literature regarding RASC. PMID:26723179

    Pelvic actinomycosis is difficult to diagnose. In most cases, it is not diagnosed until after surgery. If this condition is diagnosed preoperatively, it can be treated in many cases. Three cases of actinomycosis are reported here. Three women with intrauterine devices (IUD) each presented with lower abdominal pain and pelvic mass, and elevated white blood cell count and C-reactive protein. Left salpingo-oophorectomy was performed for one the women. The pathological diagnosis was actinomycosis. For the other two women, a Gram or Papanicolaou stain of the IUD sample showed actinomycetes. They were discharged after intravenous administration of penicillin without surgery. PMID:18001459

    The prevalence of kidney stones has steadily risen during this century; passage of a calculus and a positive family history increase the probability of recurrence. Findings from recent studies on the cause of renal calculi have stressed crystallization and crystal aggregation of stone minerals from supersaturated urine, rather than excessive organic matrix. Absence of normal urine inhibitors of calcium salts is also stressed. Formation of calcium oxalate stones is the major problem. Therapy with decreased calcium and oxalate intake, thiazides, phosphate salts and allopurinol in various combinations has substantially decreased the prevalence of recurrent stones. The rationale for the use of allopurinol is that uric acid salts enhance the tendency for calcium oxalate to crystallize from supersaturated urine. The hypercalciuria seen in 30 percent to 40 percent of patients with oxalate stones is usually caused by intestinal hyperabsorption of calcium. Although patients with uric acid calculi constitute only a small fraction of those in whom stones form, they represent a group in whom good medical therapy, based on sound physiologic principles, has proved extremely successful. Renal tubular syndromes lead to nephrocalcinosis and lithiasis through hypercalciuria, alkaline urine and hypocitraturia, the latter an inhibitor of calcium salt precipitation. Recent advances in surgical techniques are discussed, including the rationale for removing staghorn calculi. The ileal ureter and coagulum pyelolithotomy deserve special emphasis.

    The aim of this study was to establish a 3D digitized model of pelvic vasculature for anatomic study, preoperative planning, and virtual reality. Three adult fresh cadavers were perfused with carboxymethyl cellulose/lead oxide mixture to mark blood vessels, and subjected to multilayer spiral computed tomography scanning to obtain a series of thin sections. Then, the 2D images of the pelvis and pelvic blood vessels were transformed into 3D digitized models using Mimics 11.0. The 2D images of carboxymethyl cellulose/lead oxide filled arteries had the features of entire outline and few constructed defects. The 3D digitized models of the pelvis and pelvic artery system displayed spatial location and the adjacent relationship of arteries with the pelvis. Not only the well-known arteries but also the tiny blood vessels in the reconstructed structures were well demonstrated and observed interactively. The reconstructed tissue flaps, including a lobulated skin flap with the pedicle of superficial epigastric artery, and an iliac flap with the pedicle of deep iliac circumflex artery, demonstrated their blood supply area. This indicated that the modified technique of vascular perfusion with carboxymethyl cellulose/lead oxide and reconstitution with Mimics 11.0 software contributed to 3D digitized model of pelvic vasculature.

    Anterior approaches for the stabilization of anterior and also posterior B and C type instability of the pelvic ring were the standard procedures before minimally invasive percutaneous methods supported by image intensifiers or navigation devices were established. Anterior approaches are currently still of high relevance for difficult or impossible closed reductions in multiple trauma surgery where the patient must remain in a supine position. They are also used for stabilization of an increasing number of osteoporotic fractures in the elderly which are no longer only treated in specialized pelvic trauma centres. The anterior as well as the posterior part of the pelvic ring can be stabilized via various anterior approaches. A Pfannenstiel incision is appropriate for plating of ruptures of the pubic symphysis and can be extended to a modified Stoppa approach if necessary. Fractures of the iliac wings can be approached either laterally or less traumatically, via an anterolateral approach. The latter equates the lateral window of the ilioinguinal approach to the acetabulum, allows visualization of the entire sacroiliac joint and therefore stabilization of not only iliosacral luxation but also luxated fractures with a small iliac fragment. By a combination of the different approaches it is possible to simultaneously stabilize ventral and dorsal instabilities in type C fractures of the pelvic ring with a minimal amount of iatrogenic soft tissue trauma. Although the described anterior approaches are considered as simple exact knowledge of the endangered structures and general risks for each approach are essential for a safe exposure of the anatomical region addressed.

    Male genitalia evolve rapidly, probably as a result of sexual selection. Whether this pattern extends to the internal infrastructure that influences genital movements remains unknown. Cetaceans (whales and dolphins) offer a unique opportunity to test this hypothesis: since evolving from land-dwelling ancestors, they lost external hind limbs and evolved a highly reduced pelvis which seems to serve no other function except to anchor muscles that maneuver the penis. Here we create a novel morphometric pipeline to analyze the size and shape evolution of pelvic bones from 130 individuals (29 species) in the context of inferred mating system. We present two main findings: 1) males from species with relatively intense sexual selection (inferred by relative testes size) have evolved relatively large penises and pelvic bones compared to their body size, and 2) pelvic bone shape diverges more quickly in species pairs that have diverged in inferred mating system. Neither pattern was observed in the anterior-most pair of vertebral ribs, which served as a negative control. This study provides evidence that sexual selection can affect internal anatomy that controls male genitalia. These important functions may explain why cetacean pelvic bones have not been lost through evolutionary time. PMID:25186496

    Advances in tailored medical therapy and introduction of biologic agents for inflammatory bowel disease (IBD) treatment have ensured long-term disease remission. Some patients, however, still report defecatory symptoms. Patients present with a wide spectrum of conditions - anal incontinence, obstructed defecation and pelvic pain among the most frequent - that have a great impact on their quality of life. Due to IBD diagnosis, little relevance is attributed to this type of symptoms and their epidemiologic distribution is unknown. Pathogenetic hypotheses are currently under investigation. Routine diagnostic workflow and therapeutic options in pelvic floor service are often underused. The evaluation of these disorders starts with an endoscopy to rule out ongoing disease; the following diagnostic workflow is the same as in patients without IBD. For fecal incontinence and obstructed defecation, simple conservative therapy with dietary modifications and appropriate fluid intake is effective in most cases. In non-responding patients, anorectal physiology tests and imaging are required to select patients for pelvic floor muscle training and biofeedback. These treatments have been proven effective in IBD patients. Some new minimally invasive alternative strategies are available for IBD patients, as sacral nerve and posterior tibial nerve stimulation; for other ones (e.g., bulking agent implantation) IBD still remains an exclusion criterion. In order to preserve anatomical areas that could be useful for future reconstructive techniques, surgical options to cure pelvic floor dysfunction are indicated only in a small group of IBD patients, due to the high risk of failure in wound healing and to the possible side effects of surgery, which can lead to anal incontinence or to a possible proctectomy. A particular issue among defecatory symptoms in patients with IBD is paradoxical puborectalis contraction after restorative proctocolectomy: if this disorder is properly diagnosed, a conservative treatment is indicated, thus avoiding unnecessary laparotomy for small bowel occlusion. Pelvic pain management, coordinated by a specialist with expertise in pelvic floor disorders, includes many options, which vary from oral or local therapies to pelvic floor rehabilitation and sacral nerve stimulation. Surgical procedures often have unsatisfactory outcomes. Diagnosis and investigation of anorectal functional disorders in patients with IBD is important in order to implement better-suited diagnostic and therapeutic strategies, so as to avoid unnecessary and potentially detrimental medical and surgical therapies, with the final aim of improving patients' quality of life.

    Pelvic fractures range in severity from low-energy, generally benign lateral compression injuries to life-threatening, unstable fracture patterns. Initial management of severe pelvic fractures should follow Advanced Trauma Life Support protocols. Initial reduction of pelvic blood loss can be provided by binders, sheets, or some form of external fixation, which serve to reduce pelvic volume, stabilize clot formation, and reduce ongoing tissue damage. Persistently unstable patients may benefit from angiography with selective embolization, pelvic packing, or a combination of these interventions. Open pelvic fractures involving the perineum or bowel injury benefit from fecal diversion by colostomy. Trauma team coordination facilitates efficient resuscitative efforts and may affect definitive management by optimizing incision, ostomy, or catheter placement. Established protocols for both open and closed pelvic fractures help to standardize care. PMID:23908251

    Compound pelvic fractures are deemed to be one of the most severe orthopaedic injuries with an extremely high morbidity and mortality. After the initial resuscitation phase the prevention of pelvic sepsis is one of the main treatment goals for patients with an open pelvic fracture. If there is a suspicion of a rectal injury or if the wounds are in the perineal area, The Princess Alexandra Hospital's management plan includes early faecal diversion combined with vigorous soft tissue debridement, VAC(®) therapy and (if indicated) external fixation of the pelvic fracture. We present our flowchart for the treatment of trauma patients with compound pelvic fractures illustrated by a case report describing a 32 year old patient who sustained an open pelvic ring injury in a workplace accident. The aim of this paper is to underline the importance of a safe, straightforward approach to compound pelvic fractures. PMID:22222367

    [Purpose] This study investigated the effects of pelvic adjustment on pelvic posture and lower limb joint angles during walking in female university students. [Subjects] Thirty healthy female university students were randomly assigned to an experimental group (pelvic adjustment group, n = 15) and a control group (stretching group, n = 15). [Methods] Pelvic adjustment was performed three times on the experimental group. The control group performed three sets of pelvic muscle stretching for 15 minutes. A back mapper and motion analysis equipment were used to measure pelvic posture and angles of lower limb joints for the experimental and control group. [Results] The values obtained before and after the intervention were compared. For the experimental group, the results were significantly different in terms of reduced differences in hip flexion between the left and right hips and in knee abduction between the left and right knees. Differences in pelvic position and pelvic torsion were also found in the experimental group. No significant differences in the control group were identified. [Conclusion] Pelvic adjustment affects pelvic position and torsion and this enhancement to pelvic stability decreases hip flexion and knee abduction during walking. PMID:27190468

    A male infant was born at 28 weeks gestation weighing 850 g. He was diagnosed with pulmonary atresia, ventricular septal defect and major aorto-pulmonary collaterals with severely hypoplastic true pulmonary arteries. A 3.5 mm Gore-Tex central shunt was anastomosed from the ascending aorta to the main pulmonary artery at 4 months of age and a weight of 3.5 kg. The left pulmonary artery measured 1-2 mm and the right pulmonary artery measured 1 mm. His saturations increased from 70% to 85% following placement of the central shunt. At 16 months of age, his oxygen saturation decreased to 68%. Cardiac catheterization, using a retrograde approach, and angiography demonstrated a moderate degree of stenosis within the distal shunt and a severe left pulmonary arterial stenosis. A 4 x 18 mm Multi-Link Vision coronary stent was implanted within the stenotic central shunt and angioplasty of the left pulmonary arterial stenosis was performed. The oxygen saturation improved to 84% after the procedure. Although stenting of the Blalock-Taussig shunt has been described previously, this represents one of the first reports of stenting of a central aortopulmonary shunt. This significantly improved the patient's oxygen saturation and allowed the potential for some further central pulmonary arterial growth prior to unifocalization procedure. PMID:24296395

    This paper is concerned with the mathematical modeling of a severe and common congenital defect called hypoplastic left heart syndrome (HLHS). Surgical approaches are utilized for palliating this heart condition; however, a brain white matter injury called periventricular leukomalacia (PVL) occurs with high prevalence at or around the time of surgery, the exact cause of which is not known presently. Our main goal in this paper is to study the hemodynamic conditions under which HLHS physiology may lead to the occurrence of PVL. A lumped parameter model of the HLHS circulation has been developed integrating diffusion modeling of oxygen and carbon dioxide concentrations in order to study hemodynamic variables such as pressure, flow, and blood gas concentration. Results presented include calculations of blood pressures and flow rates in different parts of the circulation. Simulations also show changes in the ratio of pulmonary to systemic blood flow rates when the sizes of the patent ductus arteriosus and atrial septal defect are varied. These changes lead to unbalanced blood circulations and, when combined with low oxygen and carbon dioxide concentrations in arteries, result in poor oxygen delivery to the brain. We stipulate that PVL occurs as a consequence. PMID:26601113

    Aims. To detect anatomical and intrinsic histopathological features of the ascending aorta and left ventricular (LV) myocardium and evaluate right ventricular (RV) function in fetuses with hypoplastic left heart syndrome (HLHS). Methods. Twenty-five fetuses diagnosed with HLHS were followed up in the antenatal and postpartum periods. 12 necropsy heart specimens were analyzed for morphological and histological changes. Results. Prenatal echocardiography and pathologic anatomy displayed the typical characteristics of HLHS as a severe underdevelopment of the LV in the form of mitral stenosis or atresia or as aortic atresia or stenosis, with a decreased ratio of aortic diameter to pulmonary artery diameter (median of 0.49 with a range of 0.24 to 0.69, p ≤ 0.001) and a higher ratio of RV diameter to LV diameter (median of 2.44 with a range of 1.33 to 6.25, p ≤ 0.001). The RV volume, stroke volume, and cardiac output in HLHS fetuses were increased compared with the gestational age-matched normal controls (p < 0.01). Histological changes in the 12 HLHS specimens included LV myocardial fibrosis, aortic elastic fragmentation, and fibrosis. Conclusions. In addition to severe anatomical deformity, distinct histological abnormalities in the LV myocardium and aortic wall were identified in the fetuses with HLHS. RV function damage may be potentially exists. PMID:26981527

    Pelvic organ prolapse can affect urinary tract function by reducing flow rates and increasing post void residual urine volumes secondary to outlet obstruction. If the diagnosis is missed or left untreated, pelvic organ prolapse can lead to acute renal injury, chronic renal failure or even end stage renal disease. Herein, we present a case of a patient who presented to Albert Einstein Medical Center in Philadelphia, PA with urinary retention and acute kidney injury secondary to complete uterine prolapse, also referred to as procidentia.

    Purpose: To investigate the incidence, clinical characteristics, and risk factors of pelvic insufficiency fracture (PIF) after pelvic radiotherapy (RT) in cervical cancer. Methods and Materials: Medical records and imaging studies, including bone scintigraphy, CT, and MRI of 557 patients with cervical cancer who received whole-pelvic RT between January 1998 and August 2005 were reviewed. Results: Eighty-three patients were diagnosed as having PIF after pelvic RT. The 5-year cumulative incidence of PIF was 19.7%. The most commonly involved site was the sacroiliac joint. Pelvic pain developed in 48 patients (57.8%) at diagnosis. Eleven patients (13.3%) needed admission or narcotics because of severe pain, and others had good relief of symptoms with conservative management. In univariate analysis, age {>=}55 years (p < 0.001), anteroposterior/posteroanterior parallel opposing technique (p = 0.001), curative treatment (p < 0.001), and radiation dose {>=}50.4 Gy (p = 0.005) were the predisposing factors for development of PIF. Concurrent chemotherapy (p = 0.78) was not significant. Multivariate analysis showed that age {>=}55 years (p < 0.001), body weight <55 kg (p = 0.02), curative treatment (p = 0.03), and radiation dose {>=}50.4 Gy (p = 0.04) were significant predisposing factors for development of PIF. Conclusion: The development of PIF is not rare after pelvic RT. The use of multibeam arrangements to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture, especially in elderly women with low body weight.

  1. Pelvic actinomycosis presenting as a malignant pelvic mass: a case report

    PubMed Central

    2011-01-01

    Abstract Introduction Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. Case presentation A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period). The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. Conclusions Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy or dental infection. Surgeons should be aware of this infection in order to avoid excessive surgical procedures. PMID:21272333

  2. Directional asymmetry of pelvic vestiges in threespine stickleback.

    Extensive reduction of the size and complexity of the pelvic skeleton (i.e., pelvic reduction) has evolved repeatedly in Gasterosteus aculeatus. Asymmetrical pelvic vestiges tend to be larger on the left side (i.e., left biased) in populations studied previously. Loss of Pitx1 expression is associated with pelvic reduction in G. aculeatus, and pelvic reduction maps to the Pitx1 locus. Pitx1 knockouts in mice have reduced hind limbs, but the left limb is larger. Thus left-biased directional asymmetry of stickleback pelvic vestiges may indicate the involvement of Pitx1 in pelvic reduction. We examined 6,356 specimens from 27 Cook Inlet populations of G. aculeatus with extensive pelvic reduction. Samples from 20 populations exhibit the left bias in asymmetrical pelvic vestiges expected if Pitx1 is involved, and three have a slight, non-significant left bias. However, samples from three populations have a significant right bias, and one large sample from another population has equal frequencies of specimens with larger vestiges on the left or right side. A sample of fossil threespine stickleback also has significantly left-biased pelvic vestiges. These results suggest that silencing of Pitx1 or the developmental pathway in which it functions in the pelvis is the usual cause of pelvic reduction in most Cook Inlet populations of G. aculeatu, and that it caused pelvic reduction at least 10 million years ago in a stickleback population. A different developmental genetic mechanism is implicated for three populations with right-biased pelvic vestiges and for the population without directional asymmetry. PMID:17016807

  10. Surgical Treatment for Chronic Pelvic Pain

    PubMed Central

    1998-01-01

    The source of chronic pelvic pain may be reproductive organ, urological, musculoskeletal - neurological, gastrointestinal, or myofascial. A psychological component almost always is a factor, whether as an antecedent event or presenting as depression as result of the pain. Surgical interventions for chronic pelvic pain include: 1) resection or vaporization of vulvar/vestibular tissue for human papillion virus (HPV) induced or chronic vulvodynia/vestibulitis; 2) cervical dilation for cervix stenosis; 3) hysteroscopic resection for intracavitary or submucous myomas or intracavitary polyps; 4) myomectomy or myolysis for symptomatic intramural, subserosal or pedunculated myomas; 5) adhesiolysis for peritubular and periovarian adhesions, and enterolysis for bowel adhesions, adhesiolysis for all thick adhesions in areas of pain as well as thin ahesions affecting critical structures such as ovaries and tubes; 6) salpingectomy or neosalpingostomy for symptomatic hydrosalpinx; 7) ovarian treatment for symptomatic ovarian pain; 8) uterosacral nerve vaporization for dysmenorrhea; 9) presacral neurectomy for disabling central pain primarily of uterine but also of bladder origin; 10) resection of endometriosis from all surfaces including removal from bladder and bowel as well as from the rectovaginal septal space. Complete resection of all disease in a debulking operation is essential; 11) appendectomy for symptoms of chronic appendicitis, and chronic right lower quadrant pain; 12) uterine suspension for symptoms of collision dyspareunia, pelvic congestion, severe dysmenorrhea, cul-desac endometriosis; 13) repair of all hernia defects whether sciatic, inguinal, femoral, Spigelian, ventral or incisional; 14) hysterectomy if relief has not been achieved by organ-preserving surgery such as resection of all endometriosis and presacral neurectomy, or the central pain continues to be disabling. Before such a radical step is taken, MRI of the uterus to confirm presence of adenomyosis may be helpful; 15) trigger point injection therapy for myofascial pain and dysfunction in pelvic and abdominal muscles. With application of all currently available laparoscopic modalities, 80% of women with chronic pelvic pain will report a decrease of pain to tolerable levels, a significant average reduction which is maintained in 3-year follow-up. Individual factors contributing to pain cannot be determined, although the frequency of endometriosis dictates that its complete treatment be attempted. The beneficial effect of uterosacral nerve ablation may be as much due to treatment of occult endometriosis in the uterosacral ligaments as to transection of the nerve fibers themselves. The benefit of the presacral neurectomy appears to be definite but strictly limited to midline pain. Appendectomy, herniorraphy, and even hysterectomy are all appropriate therapies for patients with chronic pelvic pain. Even with all laparoscopic procedures employed, fully 20% of patients experience unsatisfactory results. In addition, these patients are often depressed. Whether the pain contributes to the depression or the depression to the pain is irrelevant to them. Selected referrals to an integrated pain center with psychologic assistance together with judicious prescription of antidepressant drugs will likely benefit both women who respond to surgical intervention and those who do not. A maximum surgical effort must be expended to resect all endometriosis, restore normal pelvic anatomy, resect nerve fibers, and treat surgically accessible disease. In addition, it is important to provide patients with chronic pelvic pain sufficient psychologic support to overcome the effects of the condition, and to assist them with underlying psychologic disorders.

    2007-04-01

    Advances in systemic treatment of cancer have improved patients' survival and increased the number of patients presenting with metastases of the pelvic ring. Pelvic metastatic lesions may cause severe pain and functional disability. A multidisciplinary approach is fundamental for the management of these lesions. Lesions of the pelvis not directly involving the hip joint such as the ischium, pubis or sacroiliac area can generally be treated non-operatively with radiation alone or using minimally invasive procedures of radiofrequency ablation, cryosurgery and percutaneous osteoplasty. Periacetabular destructive lesions may require total hip replacement with reconstruction of the acetabulum dependent on the extent of the defect. Operative treatment should restore the mechanical stability of the hip joint, and preserve the mobility, independence and comfort of these patients. PMID:17397844

    Introduction: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and interstitial cystitis/bladder pain syndrome collectively referred to as urologic CPPS (UCPPS) is defined by the absence of identifiable bacterial infection as a cause for the chronic pain and urinary symptoms. Methods: A PubMed search of all recent relevant articles using the keywords/phrases: CPPS, CPPS, and male pelvic pain, was conducted. Results: CPPS has a high worldwide prevalence and its negative impact on quality of life compares with or exceeds common chronic morbidities. Triggers include certain comestibles as well as psychosocial factors that promote catastrophizing and illness focused behavior. Several validated tools are currently available to help diagnose and direct targeted therapy. Treatment should begin with the most simple and least invasive based on the presenting clinical phenotype. Conclusions: Although no gold-standard treatment exists, a multidisciplinary approach with multimodal therapy gives the UCPPS patient the best chance of symptom relief. PMID:26941492

    Pelvic cancers are among the most frequently diagnosed neoplasms and radiotherapy represents one of the main treatment options. The irradiation field usually encompasses healthy intestinal tissue, especially of distal large bowel, thus inducing gastrointestinal (GI) radiation-induced toxicity. Indeed, up to half of radiation-treated patients say that their quality of life is affected by GI symptoms (e.g., rectal bleeding, diarrhoea). The constellation of GI symptoms - from transient to long-term, from mild to very severe - experienced by patients who underwent radiation treatment for a pelvic tumor have been comprised in the definition of pelvic radiation disease (PRD). A correct and evidence-based therapeutic approach of patients experiencing GI radiation-induced toxicity is mandatory. Therapeutic non-surgical strategies for PRD can be summarized in two broad categories, i.e., medical and endoscopic. Of note, most of the studies have investigated the management of radiation-induced rectal bleeding. Patients with clinically significant bleeding (i.e., causing chronic anemia) should firstly be considered for medical management (i.e., sucralfate enemas, metronidazole and hyperbaric oxygen); in case of failure, endoscopic treatment should be implemented. This latter should be considered the first choice in case of acute, transfusion requiring, bleeding. More well-performed, high quality studies should be performed, especially the role of medical treatments should be better investigated as well as the comparative studies between endoscopic and hyperbaric oxygen treatments.

    1990-02-01

    Up to 40% of vaginal deliveries lead to pelvic floor denervation. This has been linked causally with the later occurrence of urinary incontinence, faecal incontinence and vaginal prolapse. Pelvic floor position, anal sphincter pressures and anal electrosensitivity were evaluated in 72 volunteers as simple screening tests for detecting patients who might benefit from neurological assessment. A lower perineum and reduced voluntary sphincter pressures were found antenatally in parous women when compared with nulliparas. The tests were repeated postnatally 24 to 72 hours after delivery. When compared with antenatal readings, the perineum was lower and sphincter pressures were reduced in subjects delivered vaginally. Forty one subjects were reexamined after 6-8 weeks and partial recovery was found. Anal squeeze pressures and pelvic floor position when straining were the results most consistently changed. On the basis of this study it is suggested that 28% of multiparas seen anrenatally and between 25% to 30% of all women who deliver vaginally may be eligible for more detailed neurological study.

    The purpose of this study was to evaluate pelvic organ support during pregnancy and following delivery. This was a prospective observational study. Pelvic organ prolapse quantification (POPQ) examinations were performed during each trimester of pregnancy and in the postpartum. Statistical comparisons of POPQ stage and of the nine measurements comprising the POPQ between the different time intervals were made using Wilcoxon's signed rank and the paired t-test. Comparison of POPQ stage by mode of delivery was made using Fisher's exact test. One hundred thirty-five nulliparous women underwent 281 pelvic organ support evaluations. During both the third trimester and postpartum, POPQ stage was significantly higher compared to the first trimester (p<0.001). In the postpartum, POPQ stage was significantly higher in women delivered vaginally compared to women delivered by cesarean (p=0.02). In nulliparous pregnant women, POPQ stage appears to increase during pregnancy and does not change significantly following delivery. In the postpartum, POPQ stage may be higher in women delivered vaginally compared to women delivered by cesarean. PMID:15647966

  1. Recognition and Management of Nonrelaxing Pelvic Floor Dysfunction

    Faubion, Stephanie S.; Shuster, Lynne T.; Bharucha, Adil E.

    2012-01-01

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and anal sphincters. These symptoms may adversely affect quality of life. Focus on the global symptom complex, rather than the individual symptoms, may help the clinician identify the condition. The primary care provider is in a position to intervene early, efficiently, and effectively by (1) recognizing the range of symptoms that might suggest nonrelaxing pelvic floor dysfunction, (2) educating patients, (3) performing selective tests when needed to confirm the diagnosis, and (4) providing early referral for physical therapy.

    Pelvic actinomycosis is a rare chronic disease caused by actinomycete species. The pseudotumorous form is the most common and often leads to misdiagnosis. The purpose of this report is to describe two cases of pelvic actinomycosis involving women with a history of intrauterine contraceptive device (IUD) use. Diagnosis was based on pelvic mass and the findings of surgery undertaken for suspicion of an advanced ovarian tumor with hepatic metastasis in one case and for a tumor of the right ovary in the other case. Diagnosis was confirmed by histological examination of a biopsy specimen in the first case and of the surgical specimen (right ovariectomy) in the second case. Long-term antibiotic therapy was effective in both patients. Based on these two cases and review of the literature, discussion focuses on diagnostic pitfalls, natural course, and therapeutic options for this particular infection. PMID:20734602

    In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7 to 18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by 4 self-administered questionnaires and linked to the Medical Birth Registry of Norway. A total of 4.5% of the women reported new onset of pelvic pain 0 to 3 months postpartum. Compared to unassisted vaginal delivery, operative vaginal delivery was associated with increased odds of pelvic pain (adjusted odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.06-1.59). Planned and emergency cesarean deliveries were associated with reduced odds of pelvic pain (adjusted OR: 0.48; 95% CI: 0.31-0.74 and adjusted OR: 0.65; 95% CI: 0.49-0.87, respectively). Planned cesarean delivery, young maternal age, and low Symptom Checklist-8 scores were associated with low pelvic pain scores after childbirth. A history of pain was the only factor associated with increased pelvic pain scores over time (P = 0.047). We conclude that new onset of pelvic pain after childbirth was not commonly reported, particularly following cesarean delivery. Overall, pelvic pain scores were rather low at all time points and women with a history of pain reported increased pelvic pain scores over time. Hence, clinicians should follow up women with pelvic pain after a difficult childbirth experience, particularly if they have a history of pain. PMID:26588694

  5. Pelvic radiotherapy and sexual function in women

    Background During the past decade there has been considerable progress in developing new radiation methods for cancer treatment. Pelvic radiotherapy constitutes the primary or (neo) adjuvant treatment of many pelvic cancers e.g., locally advanced cervical and rectal cancer. There is an increasing focus on late effects and an increasing awareness that patient reported outcomes (PROs) i.e., patient assessment of physical, social, psychological, and sexual functioning provides the most valid information on the effects of cancer treatment. Following cure of cancer allow survivors focus on quality of life (QOL) issues; sexual functioning has proved to be one of the most important aspects of concern in long-term survivors. Methods An updated literature search in PubMed was performed on pelvic radiotherapy and female sexual functioning/dysfunction. Studies on gynaecological, urological and gastrointestinal cancers were included. The focus was on the period from 2010 to 2014, on studies using PROs, on potential randomized controlled trials (RCTs) where female sexual dysfunction (FSD) at least constituted a secondary outcome, and on studies reporting from modern radiotherapy modalities. Results The literature search revealed a few RCTs with FSD evaluated as a PRO and being a secondary outcome measure in endometrial and in rectal cancer patients. Very limited information could be extracted regarding FSD in bladder, vulva, and anal cancer patients. The literature before and after 2010 confirms that pelvic radiotherapy, independent on modality, increases the risk significantly for FSD both compared to data from age-matched healthy control women and compared to data on patients treated by surgery only. There was only very limited data available on modern radiotherapy modalities. These are awaited during the next five years. Several newer studies confirm that health care professionals are still reluctant to discuss treatment induced sexual dysfunction with patients. Conclusions Pelvic radiotherapy has a persistent deteriorating effect on the vaginal mucosa impacting negatively on the sexual functioning in female cancer patients. Hopefully, modern radiotherapy modalities will cause less vaginal morbidity but results are awaited to confirm this assumption. Health care professionals are encouraged to address potential sexual dysfunction both before and after radiotherapy and to focus more on quality than on quantity. PMID:26816824

    While exercise stress testing (EST) is an important tool, little is known about its use for determining ischemia in patients with hypoplastic left heart syndrome (HLHS) and Fontan palliation. We sought to determine the frequency of ST segment changes during EST in HLHS patients after Fontan and examine results of further testing performed in response to ST changes. A single-center chart review of HLHS patients post-Fontan from January 1995 to December 2012 was performed. Data collected included demographics, indications for EST, resting electrocardiogram findings, EST and echocardiogram results and outcomes. ESTs were evaluated for ST segment changes concerning for ischemia. Results of additional testing performed based on concerning EST findings were collected. Twenty-seven patients underwent 64 ESTs (mean 2.4 ESTs/patient). Median age at first EST was 9.6 years (range 6.2-16.4). EST was concerning for ischemia in 13 patients (48 %) on 25 (39 %) ESTs. Based on EST results, two patients had stress sestamibi testing, two underwent coronary angiography, and one had both. No reversible perfusion defects or coronary artery obstructions were demonstrated. No patient who underwent EST has died. ST segment depression was not associated with ventricular dysfunction prior to EST or at the end of follow-up (p > 0.05). In patients with HLHS post-Fontan palliation, ST segment depression on EST is common. In patients who underwent further testing, no evidence of ischemia or coronary abnormalities was found. Additional testing may not be necessary in all patients. PMID:26725480

    The objective of this study was to compare histopathological changes in hypoplastic left heart syndrome right ventricles (RV) of patients undergoing Sano and modified Blalock-Taussig (MBT) shunt and correlate them with echocardiographic findings. Myocardial tissue samples were obtained from hearts with Sano or MBT shunts after transplantation or at autopsy. Histologic sections were reviewed manually and by automated digital image analysis. Velocity vector imaging was performed on echocardiogram images obtained before transplant or death. All of these parameters were compared between the Sano and MBT shunt cohorts. A total of 14 specimens (7 Sano and 7 MBT shunt) were studied. Median age at transplant/death of Sano and MBT shunt cohorts was 11 (range 2-41) and 8 months (range 2-200), respectively. All Sano specimens had a scar at ventriculotomy site, and the mean scar area was 6.2 ± 3.3 cm(2). Compared with remote RV free wall, myocardium bordering the scar showed increased fibrosis (34 ± 16 % vs. 28 ± 14 %, p = 0.04) and thinning (0.8 ± 0.9 vs. 5.3 ± 0.8 mm; p < 0.001), which did not regress with time. The Sano ventriculotomy site showed significantly decreased velocity, strain, and strain rate compared with the corresponding contralateral segment. No focal scarring or regional hypokinesia was seen in the MBT shunt cohort. This is the first study to demonstrate histopathological features of ventriculotomy-associated RV myocardial scarring and myocardial thinning. The scarred ventriculotomy site showed decreased segmental myocardial deformation after Norwood with Sano shunt. PMID:22875140

    Objectives This study sought to investigate changes in magnetic resonance imaging (MRI) ventricular volumes and vascular dimensions before hemi-Fontan (HF) and before total cavopulmonary connection (TCPC) in children with hypoplastic left heart syndrome (HLHS). Background The systemic right ventricle (RV) in HLHS is subject to significant changes in volume loading throughout the surgical stages of palliation, particularly after the HF. Methods Fifty-eight patients had paired pre-HF and pre-TCPC MRI for assessment of changes of RV volumes, neoaortic flow, and vascular dimensions. Results Comparison of pre-HF and pre-TCPC MRI results showed a decrease of indexed RV end-diastolic volume and end-systolic volume (98 ml/m2 to 87 ml/m2 and 50 ml/m2 to 36 ml/m2, respectively) with stroke volume remaining constant (49 ml/m2 vs. 51 ml/m2), leading to an increased RV ejection fraction (51% vs. 59%). These findings persisted after excluding the 3 patients who underwent tricuspid valve repair as part of their HF procedure. Indexed RV end-diastolic volume plotted against neoaortic stroke volume demonstrated a Frank-Starling–like curve that shifted upward after HF. The indexed distal left and right cross-sectional pulmonary artery areas were reduced after HF. Conclusions In HLHS, serial MRI shows the adaptation of the systemic RV after HF with volume reduction in the context of a preserved stroke volume and an increased ejection fraction. The staged palliation in HLHS may be a risk factor particularly for reduced left pulmonary artery growth in itself as no factors investigated in this study were found to significantly impact on this.

    For patients with hypoplastic left heart syndrome who have undergone the Norwood procedure with a right ventricle-pulmonary artery (RV-PA) shunt, the shunt can either be removed or left intact at the time of the stage 2 procedure. This study aimed to determine the effects of an intact shunt on pulmonary artery growth and clinical outcomes after the stage 2 procedure. A retrospective review of patients who underwent Norwood with an RV-PA shunt from 2005 to 2010 was performed. Catheterization data, echocardiographic data, postoperative outcome variables, and mortality data were collected. Pulmonary artery size was measured at pre-stage 2 and pre-Fontan catheterizations using the Nakata Index and the McGoon Ratio. Of the 68 patients included in the study, 48 had the shunt removed at the time of stage 2 (group 1), and 20 had the shunt left intact (group 2). The two groups did not differ in terms of pre-stage 2 hemodynamics or pulmonary artery size. After stage 2, group 2 had higher oxygen saturations. The two groups did not differ regarding duration of chest tube drainage, length of hospital stay, need for unplanned interventions, or mortality. Before Fontan, the group 2 patients had higher superior vena cava (SVC) pressures and more venovenous collaterals closed. There was increased pulmonary artery growth between the pre-stage 2 and pre-Fontan catheterizations in group 2 using both the Nakata Index (+148.5 vs -52.4 mm(2)/m(2); p = 0.01) and the McGoon Ratio (+0.36 vs +0.01; p = 0.01). These findings indicate that patients with an intact RV-PA shunt after stage 2 have greater pulmonary artery growth than patients with the shunt removed, with no increased risk of complications.

Pelvic actinomycosis is a chronic granulomatous disease caused by Actinomyces israelii that frequently mimics ovarian tumors during presentation. It is diagnosed after surgery in most of the cases. Intravenous penicillin is the most preferred therapeutic agent, and it requires hospitalization up to one month. Pelvic actinomycosis is a rare cause of ureteric obstruction and renal failure. The final diagnosis is usually difficult and often apparent only after histological examination of an operative specimen. The present case led us to consider the etiology and clinical findings and to review the management of reported cases involving ureteric obstruction. PMID:24523972

    Pelvic venous insufficiency is a frequent pathology in multiparous women. Diagnosis can be made by chance or suspected in the case of symptoms suggesting pelvic congestion syndrome or atypical lower limb varicosity fed by pelvic leaks. After ultrasound confirmation, dynamic venography is the reference pretherapeutic imaging technique, searching for pelvic varicosity and possible leaks to the lower limbs. MRI is less invasive and allows a three-dimensional study of the varicosity and, with dynamic angiography, it can assess ovarian reflux. It also helps to plan or even sometimes avoid diagnostic venography. PMID:24630150

    Despite longstanding interest in parallel evolution, little is known about the genes that control similar traits in different lineages of vertebrates. Pelvic reduction in stickleback fish (family Gasterosteidae) provides a striking example of parallel evolution in a genetically tractable system. Previous studies suggest that cis-acting regulatory changes at the Pitx1 locus control pelvic reduction in a population of threespine sticklebacks (Gasterosteus aculeatus). In this study, progeny from intergeneric crosses between pelvic-reduced threespine and ninespine (Pungitius pungitius) sticklebacks also showed severe pelvic reduction, implicating a similar genetic origin for this trait in both genera. Comparative sequencing studies in complete and pelvic-reduced Pungitius revealed no differences in the Pitx1 coding sequences, but Pitx1 expression was absent from the prospective pelvic region of larvae from pelvic-reduced parents. A much more phylogenetically distant example of pelvic reduction, loss of hindlimbs in manatees, shows a similar left–right size bias that is a morphological signature of Pitx1-mediated pelvic reduction in both sticklebacks and mice. These multiple lines of evidence suggest that changes in Pitx1 may represent a key mechanism of morphological evolution in multiple populations, species, and genera of sticklebacks, as well as in distantly related vertebrate lineages.

    Major pelvic ring fracture (PRF) due to blunt trauma results in lower urinary tract injury (LUTI) in up to 10% of cases. Significant comorbidity may result and this is particularly the case for unrecognised injury. The increase in military injuries due to improvised explosive devices in recent conflicts has revealed a complex injury cohort. The incidence of pelvic fracture related LUTI in these casualties is up to three times higher than that seen in civilian patients with pelvic fracture. A complete understanding of LUTI following pelvic fracture is still lacking. Complex fractures of the anterior pelvic arch are associated with LUTI and initial management is largely conservative. In battlefield injuries, the combination of the blast wave, penetrating fragment and bodily displacement results in open pelvic fracture combined with gross perineal and pelvic soft-tissue destruction and traumatic femoral amputations. These are some of the most challenging injuries that any surgical team will manage and life saving measures are the priority. There are established pathways for the management of LUTI following blunt trauma related pelvic fracture. Military injuries are more complex and require a significantly different approach. This paper outlines the developments in the understanding and management of pelvic fracture-related LUTI, focussing primarily on injury mechanisms and early management. Recent military surgical experience is discussed, highlighting the significant differences to civilian practice. PMID:23631324

    A black kidney has 3 major differential diagnoses: hemosiderosis, lipofuscin pigment and melanotic renal cell carcinoma. Excluding lipofuscin, the other 2 are accompanied by an abnormal renal function. We report on a 25-year-old man who intended to donate a kidney to his cousin. On the operating room table when we incised the left flank region and exposed the kidney, we found a firm and black kidney so the operation was cancelled due to potential vascular injuries. Days after the incomplete procedure, we reviewed the donor’s biochemistry and imaging to reassess his renal function, but the results showed quite normal renal function again. The result of Ham test was also negative. Two weeks later, we began the operation, removed the same left kidney and found that it was in the same conditions as it was before. We took the opportunity to send needle biopsies of the kidney for histopathologic analysis. The analysis showed a melanotic kidney without pathological changes in glomeruli and interstitium and vessels. A black kidney may result in hemosiderin, lipofuscin or melanin deposits in the kidney, which can confirm the diagnosis; however, special tests for underlying disease and renal function should be considered. Some causes of black kidney lead to abnormal function, but our patients’s kidney returned to normal. PMID:24839502

    Hypoplastic left heart syndrome (HLHS) is a severe congenital heart disease that is uniformly fatal without surgical intervention. Fetal echocardiography allows prenatal diagnosis, but this condition may not become apparent until after the mid-second trimester. We report a term baby with severe HLHS who had an 18 week fetal ultrasound that reportedly demonstrated a normal heart. There was no family history of congenital heart disease. She was phenotypically female with no dysmorphic features. Physical examination was otherwise normal. She expired at 48 hours of age. The autopsy was noncontributory. The karyotype was 46,XX, but there was an apparently balanced paracentric inversion of the long arm of chromosome 7 (46,XX,inv(7)(q21.2q22)). The mother`s chromosome study was normal without any inversion, and the father was not available for study. Hypoplastic left heart syndrome has been associated with extracardiac anomalies and chromosomal abnormalities including 45,XO,11q-, and trisomy 18. It has also been reported in 5 members spanning 3 generations of a family with a spectrum of left heart defects suggesting an autosomal dominant pattern with high penetrance. First-degree relatives of infants with HLHS have a thirteen percent incidence of related cardiovascular malformations, a frequency higher than predicted by a multifactorial model of inheritance, suggesting that at least a portion of HLHS have a genetic basis. Karyotype analysis, including high resolution banding, may help define the etiology of this condition. Chromosome 7 has not been implicated in HLHS. This case emphasizes the need for genetic analysis, including a pedigree, of affected families. It also underscores the importance of screening by karyotype analysis to determine whether defects of the long arm of chromosome 7 are important in the pathogenesis of hypoplastic left heart syndrome.

    Magnetic resonance (MR) imaging is gaining increased acceptance in the emergency setting despite the continued dominance of computed tomography. MR has the advantages of more precise tissue characterization, superior soft tissue contrast, and a lack of ionizing radiation. Traditional barriers to emergent MR are being overcome by streamlined imaging protocols and newer rapid-acquisition sequences. As the utilization of MR imaging in the emergency department increases, a strong working knowledge of the MR appearance of the most commonly encountered abdominopelvic pathologies is essential. In this article, MR imaging protocols and findings of acute pelvic, scrotal, and gastrointestinal pathologies are discussed. PMID:27150327

    Traditional closed reductions of unstable pelvic fractures are mainly performed by surgeons using manual manipulation and subjective verification based on intra-operative roentgenography. It is difficult to perform an accurate closed reduction because of a lack of adequate knowledge of the displacement patterns and an inability to apply the reduction in correct direction. Using the concept of the remote center of motion mechanism and computer-aided design software, we developed a pelvic reduction frame for use in anatomical closed reductions of unstable pelvic fractures. With three-dimensional reconstruction technique and the matrix algorithm, the spatial orientation of the displaced hemipelvis can be calculated and deconstructed into several rotational and translational movements that can be completed with the frame. To verify the accuracy of this system, the rotations were repeated 10 times in arbitrary degrees and directions. After the matrix is calculated, the displaced hemipelvis can be reduced to the anatomical position using our frame. The maximum residual translational and rotational displacements were less than 5 mm and 4 degrees, which indicated the accuracy of this system. The maximum average residual translation and rotation were 1.87 mm in Z-axis (ranging: 4.63-0.1 mm) and 1.1 degrees around Y-axis (ranging: 3.81-0.13 degrees), respectively. Only the Z-axial translation showed a statistically significant difference (p < 0.05). In conclusion, the proposed pelvic reduction frame could be a useful tool for the anatomical reduction of unstable pelvic fractures. © 2015 Orthopaedic Research Society.

    Introduction and Hypothesis We evaluated the associations between pelvic floor muscle strength and tone with sexual activity and sexual function in women with pelvic floor disorders. Methods This was a secondary analysis of a multicenter study of women with pelvic floor disorders from the US and UK performed to validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR). Participants were surveyed about whether they were sexually active and completed the PISQ-IR and Female Sexual Function Index (FSFI) questionnaires to assess sexual function. Physical exams included assessment of pelvic floor strength by the Oxford Grading Scale, and assessment of pelvic floor tone per ICS guidelines. Results The cohort of 585 women was middle aged (mean age 54.9 +/−12.1) with 395 (67.5%) reporting sexual activity. Women with a strong pelvic floor (n=275) were more likely to report sexual activity than women with weak strength (n=280) (75.3 vs. 61.8%, p<0.001), but normal or hypoactive pelvic floor tone was not associated with sexual activity (68.8 vs. 60.2%, normal vs. hypoactive, p=0.08). After multivariable analysis, a strong pelvic floor remained predictive of sexual activity (OR 1.89, CI 1.18–3.03, p<0.01). Among sexually active women (n=370), a strong pelvic floor was associated with higher scores on the PISQ-IR domain of condition impact (Parameter Estimate 0.20+/−0.09, P=0.04), and FSFI orgasm domain (PE 0.51+/−0.17, P=0.004). Conclusion A strong pelvic floor is associated with higher rates of sexual activity as well as higher sexual function scores on the condition impact domain of the PISQ-IR and orgasm domain of the FSFI.

    Pelvic dissociation is a rare but serious potential complication of total hip arthroplasty. The purpose of this study is to evaluate the effectiveness of the false profile view compared with traditional radiographs in detecting pelvic dissociation. Ten cadaver pelves were skeletonized, and noncemented acetabular hip arthroplasty components were implanted. Anteroposterior, lateral, iliac oblique, and false profile radiographs were obtained before and after creating pelvic dissociations and analyzed in a blinded fashion. The sensitivity of the false profile view for detecting pelvic dissociation was 79% (confidence interval, 70-86), which was greater than the sensitivity for anteroposterior and lateral views. This difference was statistically significant. False profile views are a potentially valuable addition to the traditional radiographic evaluation of pelvic discontinuity in hip arthroplasty.

    [Purpose] This study aimed to determine the correlation between pelvic floor muscle strength and pulmonary function. In particular, we examined whether pelvic floor muscle exercises can improve pulmonary function. [Subjects] Thirty female college students aged 1921 with no history of nervous or musculoskeletal system injury were randomly divided into experimental and control groups. [Methods] For the pulmonary function test, spirometry items included forced vital capacity and maximal voluntary ventilation. Pelvic floor muscle exercises consisted of Kegel exercises performed three times daily for 4 weeks. [Results] Kegel exercises performed in the experimental group significantly improved forced vital capacity, forced expiratory volume in 1 second, PER, FEF 2575%, IC, and maximum voluntary ventilation compared to no improvement in the control group. [Conclusion] Kegel exercises significantly improved pulmonary function. When abdominal pressure increased, pelvic floor muscles performed contraction at the same time. Therefore, we recommend that the use of pelvic floor muscle exercises be considered for improving pulmonary function. PMID:26644681

    2004-07-22

    Birds and crocodylians, the only living archosaurs, are generally believed to employ pelvic girdle movements as a component of their respiratory mechanism. This in turn provides a phylogenetic basis for inferring that extinct archosaurs, including dinosaurs, also used pelvic girdle breathing. I examined lung ventilation through cineradiography (high-speed X-ray filming) and observed that alligators indeed rotate the pubis to increase tidal volume, but did not observe pelvic girdle movement contributing to lung ventilation in guinea fowl, emus or tinamous, despite extensive soft-tissue motion. Re-examination of fossil archosaurs reveals that pubic rotation evolved in basal crocodyliforms and that pelvic girdle breathing is not a general archosaurian mechanism. The appearance of pelvic aspiration in crocodyliforms is a striking example of the ability of amniotes to increase gas exchange or circumvent constraints on respiration through the evolution of novel accessory breathing mechanisms.

    Pelvic abscesses are usually the end stage in the progression of an infection. They may occur from surgical complications, generalized abdominal infections such as appendicitis or diverticulitis, or from localized infections such as pelvic inflammatory disease or inflammatory bowel disease. Although surgery has been considered as the treatment of choice by some authors, pelvic abscesses can be managed by non-invasive methods such as ultrasound and computed tomography-guided drainage. The development of therapeutic linear echoendoscopes has allowed the endoscopist to perform therapeutic procedures. Recently, endoscopic ultrasonography (EUS)-guided drainage of pelvic collections has been demonstrated to be feasible, efficient and safe. It allows the endoscopist to insert stents and drainage catheters into the abscess cavity which drains through the large bowel. This article reviews technique, current results and future prospects of EUS-guided drainage of pelvic lesions. PMID:21160937

    Total pelvic exenteration is a highly morbid procedure performed for locally advanced pelvic malignancies. We describe our experience with three patients who underwent robotic total pelvic exenteration with laparoscopic rectus flap and compare perioperative characteristics to our open experience. Demographic, tumor, operative, and perioperative factors were examined with descriptive statistics reported. Mean operative times were similar between the two groups. When compared to open total pelvic exenteration cases (n = 9), median estimated blood loss, ICU stay, and hospital stay were all decreased. These data show robotic pelvic exenteration with laparoscopic rectus flap is technically feasible. The surgery was well tolerated with low blood loss and comparable operative times to the open surgery. Further study is needed to confirm the oncologic efficacy and the suggested improvement in surgical morbidity. PMID:25960911

Renal impairment, especially stage 4-5 chronic kidney disease, increases the risk of: (i) the prevalence and incidence (in dialysis/transplantation) of hepatitis C virus (HCV) infection; (ii) liver deterioration during kidney transplantation and (iii) allograft failure and patient mortality. HCV-infected dialysis patients have a higher mortality than non-infected dialysis patients and than HCV-infected kidney recipients. The harmful impact of HCV emphasizes the need for oral antiviral therapies in patients with chronic kidney disease. Symptomatic cryoglobulinemic vasculitis and extensive liver fibrosis are already approved indications for early access to oral antiviral treatment. Patients with stage 4-5 chronic kidney disease should also be given priority: dialysis patients (whatever the stage of fibrosis and whether or not they are candidates for kidney transplantation) as well as all kidney recipients. The results of treatment of HCV with direct-acting antiviral (DAAs) drugs in patients with late chronic kidney disease are excellent, similar to those in the general population, although additional clinical trials are definitely needed, particularly to optimize adjustment of treatment to kidney function and determine the risk of drug-drug interactions.

    The current kidney allocation system for transplants is outdated and has not evolved to reflect the changing demographics of patients on the waiting list. This article proposes a new system for kidney allocation, which more appropriately incorporates the biology of highly sensitized patients into the waiting-time scoring algorithm. This system will significantly reduce mismatches between possible donor kidney longevity and life expectancy of recipients, and makes incremental advances toward more geographic sharing. The proposed system makes significant progress toward eliminating deficiencies in the current system, and has the potential to increase the supply of available kidneys. PMID:24206858

    Dialysis and kidney transplantation, current therapies for kidney failure, have limitations such as severe complications, donor shortage, and immune-related problems. The development of an alternative treatment for kidney failure is demanded. The present study shows that the transplantation of fetal kidney cells reconstitutes functional kidney tissue, and that the gestation stage of kidney cells influences the kidney reconstitution. Fetal kidney cells were isolated from metanephroi of rat fetuses at various gestation stages and transplanted into the omentum or kidney of immunodeficient mice. Immunophenotype analysis of fetal kidney cells showed apparent expression of stem cell markers. Three weeks after transplantation, histological analyses of retrieved grafts revealed the formation of kidney structures, including fluorescently labeled transplanted cells, suggesting the potential of fetal kidney cells to reconstitute kidney tissues. The grafts retrieved from omentum contained cystic fluids with concentrated solutes. However, transplanted early fetal kidney cells had also differentiated into nonrenal tissues such as bone and cartilage. In addition, transplantation of fetal kidney cells from a later gestation stage resulted in poor kidney structure formation. Kidney-specific genes were strongly expressed in the earlier cell transplants. The cells at an earlier gestation stage had higher colony forming ability than the cells at a later stage. This study demonstrates the reconstitution of kidney tissue by transplanting fetal kidney cells and the presence of an optimal time window in which fetal kidney cells regenerate kidney tissues. Disclosure of potential conflicts of interest is found at the end of this article. PMID:17548530

    Pelvic external fixators have a high rate of reported complications, most of which relate to pin placement. In this descriptive study, we analyzed the morphology of the ilium in cadaveric specimens and compared these with the measures obtained from normal human pelvic computer tomograph scans, and how these related to each of the three basic configurations of pin positioning for the external fixation of a pelvis: anterosuperior (Slätis type), anteroinferior (supra-acetabular), and subcristal. The irregular shape and size of the iliac wing and the abdominal wall overlying the pin's insertion site could hinder accurate placement of anterosuperior pins. Potential disadvantages of the use of anteroinferior pins was found related to the deep location of the anterior inferior iliac spine, interference with the hip flexion area, risk of hip joint penetration, and the variable obliquity of the ilium. As subcristal pins are positioned between two superficial bony landmarks of the iliac crest, our findings suggest that they are more likely to have a correct placement and avoid complications.

    Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed. PMID:25785286

    The cause of chronic pelvic pain syndrome (CPPS) has yet to be established. Since the late 1980s, cytokine, chemokine, and immunological classification studies using human samples have focused on identifying biomarkers for CPPS, but no diagnostically beneficial biomarkers have been identified, and these studies have done little to deepen our understanding of the mechanisms underlying chronic prostatic pain. Given the large number of men thought to be affected by this condition and the ineffective nature of current treatments, there is a pressing need to elucidate these mechanisms. Prostatitis types IIIa and IIIb are classified according to the presence of pain without concurrent presence of bacteria; however, it is becoming more evident that, although levels of bacteria are not directly associated with levels of pain, the presence of bacteria might act as the initiating factor that drives primary activation of mast-cell-mediated inflammation in the prostate. Mast cell activation is also known to suppress regulatory T cell (Treg) control of self-tolerance and also activate neural sensitization. This combination of established autoimmunity coupled with peripheral and central neural sensitization can result in the development of multiple symptoms, including pelvic pain and bladder irritation. Identifying these mechanisms as central mediators in CPPS offers new insight into the prospective treatment of the disease. PMID:24686526

    The clinical picture in and efficacy of physical treatment for pelvic floor myalgia were reviewed. The medical records of patients having a diagnosis of pyriformis syndrome, coccygodynia, levator ani spasm syndrome, proctalgia fugax, or rectal pain who had been seen at the Mayo Clinic and treated in the Department of Physical Medicine and Rehabilitation from 1970 through 1975 were retrieved. Adequate information and follow-up were available for 94 patients. Seventy-eight patients were women and 16 were men, whose ages ranged from 26 to 72 years. All patients had tenderness of the pelvic floor muscles on rectal examination. The most common associated findings were poor posture, deconditioned abdominal muscles, and generalized muscle attachment tenderness. The most effective therapeutic regimen was a combination of rectal diathermy, Thiele's massage, and relaxation exercises. Of the 94 patients, 30 had complete resolution of their symptoms, 19 had marked improvement, 17 had moderate improvement, and 14 had mild improvement. Only 14 patients had no change and 1 patient was worse after treatment. PMID:926848

    Chronic pelvic pain (CPP) could be considered nowadays a deep health problem that challenges physicians all over the world. This because its aetiology is still unclear, the course of the disease could vary a lot among different patients and through time in the same patient, and the response to treatments is not every time successful. Among women who underwent laparoscopy for CPP, endometriosis is found in about 1/3 of the cases, while only 25% of women with histological confirmed endometriosis are asymptomatic. A wide range of variables may exert their influence on the resulting pain syndrome in endometriosis; for example, score according to American society for reproductive medicine (rASRM), size of the sub-peritoneal and pelvic wall implants, Douglas obliteration, previous surgery. It is widely accepted nowadays that central nervous system (CNS) and peripheral nervous system (PNS) seems to influence each other and this interconnection play a key role in pain modulation. Moreover, the phenomena induced by endometriosis in the pelvis, including the breakdown of peritoneal homeostasis and the induction of the production of proinflammatory and proangiogenic cytokines, are responsible of altered innervations and modulation of pain pathways in these patients. There are many proposed medical and surgical approach to treat this painful syndrome, although there is necessity of more efforts to create new non-invasive strategies that set a more accurate diagnosis of the causes of endometriotic-related CPP, and therefore facilitate its eradication.

  1. Limbic associated pelvic pain: a hypothesis to explain the diagnostic relationships and features of patients with chronic pelvic pain.

    PubMed

    Fenton, Bradford W

    2007-01-01

    Limbic associated pelvic pain is a proposed pathophysiology designed to explain features commonly encountered in patients with chronic pelvic pain, including the presence of multiple pain diagnoses, the frequency of previous abuse, the minimal or discordant pathologic changes of the involved organs, the paradoxical effectiveness of many treatments, and the recurrent nature of the condition. These conditions include endometriosis, interstitial cystitis, irritable bowel syndrome, levator ani syndrome, pelvic floor tension myalgia, vulvar vestibulitis, and vulvodynia. The hypothesis is based on recent improvements in the understanding of pain processing pathways in the central nervous system, and in particular the role of limbic structures, especially the anterior cingulate cortex, hippocampus and amygdala, in chronic and affective pain perception. Limbic associated pelvic pain is hypothesized to occur in patients with chronic pelvic pain out of proportion to any demonstrable pathology (hyperalgesia), and with more than one demonstrable pain generator (allodynia), and who are susceptible to development of the syndrome. This most likely occurs as a result of childhood sexual abuse but may include other painful pelvic events or stressors, which lead to limbic dysfunction. This limbic dysfunction is manifest both as an increased sensitivity to pain afferents from pelvic organs, and as an abnormal efferent innervation of pelvic musculature, both visceral and somatic. The pelvic musculature undergoes tonic contraction as a result of limbic efferent stimulation, which produces the minimal changes found on pathological examination, and generates a further sensation of pain. The pain afferents from these pelvic organs then follow the medial pain pathway back to the sensitized, hypervigilant limbic system. Chronic stimulation of the limbic system by pelvic pain afferents again produces an efferent contraction of the pelvic muscles, thus perpetuating the cycle. This cycle is susceptible to disruption through blocking afferent signals from pelvic organs, either through anesthesia or muscle manipulation. Disruption of limbic perception with psychiatric medication similarly produces relief. Without a full disruption of both the central hypervigilance and pelvic organ dysfunction, pain recurs. To prevent recurrence, clinicians will need to include some form of therapy, either medical or cognitive, targeted at the underlying limbic hypervigilance. Further research into novel, limbic targeted therapies can hopefully be stimulated by explicitly stating the role of the limbic system in chronic pain. This hypothesis provides a framework for clinicians to rationally approach some of the most challenging patients in medicine, and can potentially improve outcomes by including management of limbic dysfunction in their treatment.

    Haemorrhage from severe pelvic fractures can be associated with significant mortality. Modern civilian trauma centres may manage these injuries with a combination of external pelvic fixation, extra-peritoneal packing and/or selective angiography; however, military patterns of wounding are different and deployed medical facilities may be resource constrained. We report two successful instances of pelvic packing using chitosan impregnated gauze (Celox) when conventional surgical attempts at vascular control had failed. We conclude that pelvic packing should be considered early in patients with military pelvic trauma and major haemorrhage, as part of damage control surgery and that Celox gauze may be a useful adjunct. In our cases, the Celox gauze was easily removed after 24-48 hours without significant bowel adhesions and did not leave a residual phelgmon (of exudate or gel) that may predispose to infection.

  5. Ureteric obstruction due to pelvic actinomycosis.

    1982-03-01

    Since 1973 several reports of pelvic actinomycosis arising in association with modern types of IUDs have appeared. Various presentations occur such as vaginal discharge, tubo-ovarian abscess, or "frozen pelvis." Ureteric obstruction is uncommon and its management unclear. A case is presented of ureteric obstruction due to pelvic actinomycosis associated with an IUD. A 34 year old woman presented with a 6 month history of alternating constipation and diarrhea, weight loss, amenorrhea, and laterally, a vaginal discharge. A Lippes loop had been inserted 2 years earlier. On examination, she was anemic, cachectic, pyrexial and had a frozen pelvis. There was a stricture of the midrectum but the mucosa was intact. The strings of the IUD could be felt and the cervix appeared normal. There was skin redness and induration over the right ischiorectal fossa. Intravenous urogram showed bilateral hydronephrosis with hydroureter. Examination under anesthesia confirmed the midrectal stricture. Biopsies showed mild inflammatory changes only. The IUD was removed and curettings revealed an acute endometritis. At laparotomy, apparently normal small bowel loops were adherent to a friable mass in the pelvis, which displaced the bladder forwards. The colon and uterus appeared normal but bilateral pyosalpinges were present and were resected. Neither ovary could be identified. Despite the tubal infection, pelvic malignancy was suspected and a sigmoid colostomy fashioned in view of impending rectal obstruction. Histology of the mass showed a large amount of fibrous tissue infiltrated by acute and chronic inflammatory cells and containing micro-abscesses. In 2 places only, colonies of actinomycetes surrounded by polymorphs were observed. No sulphur granules were identified. No growth was obtained on aerobic and anaerobic culture of the tissue and the pyosalpinges. Treatment with penicillin V 500 mg q.d.s. produced an allergic reaction and was changed to tetracycline 250 mg q.d.s. which was continued for 2 months at home. 4 months later, the rectal stricture had resolved and the colostomy was closed. 9 months after the initial presentation a urogram showed complete resolution of the left hydronephrosis. There was slight residual right hydronephrosis but no evidence of ureteric obstruction. PMID:7066656

    One in ten Americans suffer from chronic kidney disease, and close to 90,000 people die each year from causes related to kidney failure. Patients with end-stage renal disease are faced with two options: hemodialysis or transplantation. Unfortunately, the reach of transplantation is limited because of the shortage of donor organs and the need for immunosuppression. Bioengineered kidney grafts theoretically present a novel solution to both problems. Herein we discuss the history of bioengineering organs, the current status of bioengineered kidneys, considerations for the future of the field, and challenges to clinical translation. We hope that by integrating principles of tissue engineering, and stem cell and developmental biology, bioengineered kidney grafts will advance the field of regenerative medicine while meeting a critical clinical need.

    Kidney transplantation is the best approach for treating patients with end stage renal disease, offering patients the best chance of returning to normal health. While the techniques used in kidney transplantation surgery are mature and highly successful, there is a severe shortage of donor organs. Statistics show a serious imbalance between organ donations and patients on the waiting list for organ transplantation. Moreover, evidence from empirical studies has shown a better transplantation outcome for patients who receive living donor transplantation than for those who receive organs from cadavers. Although using relatives as donors offers an effective way to reduce the problem of organ shortage, this strategy faces many challenges and many other factors affect the promotion of living donor transplantation. This article elaborates how cultural and psychological factors, kidney transplantation awareness, and ethics and laws impact upon living kidney donations and then proposes coping strategies for promoting living kidney transplantation.

    Objectives To identify the prevalence of sleep disturbance in women seeking treatment for pelvic organ prolapse (POP) and identify correlates of poor sleep quality in this population by using a validated sleep scale. Study Design This is a cohort study of female patients with pelvic organ prolapse. Main Outcome Measures Pittsburgh Sleep Quality Index (PSQI), Pelvic Floor Disorders Inventory (PFDI), and Pelvic Floor Impact Questionnaire (PFIQ) measures were completed. Demographic data, medical comorbidities, medications, and physical examinations were also recorded. Results 407 women were enrolled. Analysis was performed on the 250 subjects who completed all PSQI components. Subjects were predominantly white, with a mean age of 61±11 years and mean BMI of 28±5kg/m2. The majority (71%) had Stage III prolapse. Half (N=127) had poor sleep quality (PSQI >5). Women with poor sleep quality were younger, had more medical comorbidities, more pelvic floor symptoms, more nocturia, more depressive symptoms, and took more time to fall asleep. Factors associated with sleep quality were evaluated using multivariable linear regression models. Worse sleep scores were associated with each of the PFDI subscores (urinary, prolapse, bowel), depressive symptoms, severe nocturia symptoms, and number of comorbidities. Conclusions Poor sleep is prevalent in women with prolapse. Pelvic floor symptoms as measured by PFDI sub-scales, were associated with poor sleep quality. Future studies are needed to better understand how sleep disturbances may contribute to the impact of pelvic floor symptoms on quality of life. PMID:25465518

  9. The MAPP research network: a novel study of urologic chronic pelvic pain syndromes

    PubMed Central

    2014-01-01

    Urologic chronic pelvic pain syndrome (UCPPS) may be defined to include interstitial cystitis/bladder pain syndrome (IC/BPS) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). The hallmark symptom of UCPPS is chronic pain in the pelvis, urogenital floor, or external genitalia often accompanied by lower urinary tract symptoms. Despite numerous past basic and clinical research studies there is no broadly identifiable organ-specific pathology or understanding of etiology or risk factors for UCPPS, and diagnosis relies primarily on patient reported symptoms. In addition, there are no generally effective therapies. Recent findings have, however, revealed associations between UCPPS and “centralized” chronic pain disorders, suggesting UCPPS may represent a local manifestation of more widespread pathology in some patients. Here, we describe a new and novel effort initiated by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the U.S. National Institutes of Health (NIH) to address the many long standing questions regarding UCPPS, the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network. The MAPP Network approaches UCPPS in a systemic manner, in which the interplay between the genitourinary system and other physiological systems is emphasized. The network’s study design expands beyond previous research, which has primarily focused on urologic organs and tissues, to utilize integrated approaches to define patient phenotypes, identify clinically-relevant subgroups, and better understand treated natural history and pathophysiology. Thus, the MAPP Network provides an unprecedented, multi-layered characterization of UCPPS. Knowledge gained is expected to provide important insights into underlying pathophysiology, a foundation for better segmenting patients for future clinical trials, and ultimately translation into improved clinical management. In addition, the MAPP Network’s integrated multi-disciplinary research approach may serve as a model for studies of urologic and non-urologic disorders that have proven refractory to past basic and clinical study.

  10. Intervention in the critically ill neonate and infant with hypoplastic left heart syndrome and intact atrial septum.

    2001-06-01

    Neonates that present with hypoplastic left heart syndrome (HLHS) and intact atrial septum (IAS) pose a major management problem for the pediatric cardiac team. They are critically ill newborns with profound hypoxemia and acidosis that require immediate attention. Controversy exists as to the most appropriate management strategy. In one series where a primary and emergent surgical-staged reconstructive procedure was performed, the in-house hospital mortality was 65% and the overall survival was 17%. With equal abysmal results, transcatheter creation of an atrial septal defect (ASD) using conventional balloon atrial septostomy (BAS) with or without the combination of blade atrial septotomy had an unacceptable high risk of cardiac perforation leading to tamponade and death. However, using more modern transcatheter techniques of transseptal perforation of the atrial septum followed by progressive and serial balloon septoplasty, creating an ASD, significantly reduced the risk of the procedure. In one series, 16 consecutive neonates underwent this type of interventional procedure without procedural mortality. The management strategy of creating an ASD in the catheterization lab followed by Stage I reconstructive surgical repair 3-5 days after the initial catheterization procedure improved the in-house survival to 57%. Unfortunately, there continues to be significant attrition of these patients undergoing Stage II and III reconstructive repair, which supports cardiac transplantation as an alternative strategy. There have been echocardiographic and histopathologic studies of these neonates, and an important echo classification of left atrial morphology has been described with perhaps some prognostic implication. In addition, autopsy specimens have demonstrated significant "arterialization" of the pulmonary venous architecture that likely dooms the patient with single ventricle physiology to a poor outcome. Future improvement in transcatheter techniques and materials offer promise in palliating these critically ill neonates. The concept of radiofrequency energy perforating catheters has great merit and may reduce the risk of cardiac perforation as compared with the rigid and long transseptal needle. Echocardiographic imaging at the time of entry through the IAS may improve the safety as well. The novel concepts of "butterfly" or "dog-bone" stents placed across the atrial septum creates a precisely sized ASD that may be more conducive to effectively lower left atrial hypertension, yet avoids excessive pulmonary blood flow associated with large atrial communications. In addition, new materials, such as the Cutting Balloon Catheter, may offer promise in creating ASDs in these patients. A more aggressive approach would be to consider intrauterine fetal transcatheter opening of the IAS using modified techniques that have been attempted for left ventricular outflow tract obstruction. Unfortunately to date, the results of attempted relief of aortic valve stenosis have been extremely poor. Finally, we as interventionalists need to continue to improve our skills to help in the complex management of these critically ill neonates and infants. Only through continued efforts of the entire cardiac team of intensivists, cardiologists, cardiothoracic surgeons, and interventionalists will our management strategy be defined to maximize the future outcome in this group of patients.

    A 38-year-old woman presented with light vaginal bleeding at approximately 8 weeks gestation. Although she initially presented to accident and emergency with vaginal bleeding and menstrual-like pain, this rapidly settled and both symptoms resolved over the following days. An initial ultrasound scan revealed an empty uterus, with no adnexal masses or free fluid. Miscarriage was presumed. However, following suboptimal β-human chorionic gonadotropin decline, further ultrasonography noted a mass next to the right ovary. The patient underwent laparoscopy, revealing an ectopic pregnancy closely adherent to the peritoneum of the right pelvic wall. The patient was treated with systemic methotrexate and responded well. This rare form of ectopic pregnancy has a high maternal morbidity and mortality, and its optimal management is not definitively decided, due to the scarcity of the condition and subsequent lack of high-powered data. We present a case of successful medical management. PMID:26424823

    Rhabdomyosarcomas are soft-tissue tumors, rare in adults. Accounting for nearly 5% of childhood cancers, they represent less than 0.03% of adult malignancies (1, 2). Three different subtypes of rhabdomyosarcoma have been described (embryonal, alveolar and pleomorphic), making up approximately 50%, 30%, and 20% of the cases, respectively (3). Although the definitive diagnosis is made pathologically, some distinguishing features among these subtypes, and between rhabdomyosarcomas and other soft-tissue tumors, can be suggested on MRI and CT. We present an interesting case of a 20-year-old female with a locally aggressive pelvic alveolar rhabdomyosarcoma. While the prognosis has improved with newer treatment techniques, overall survival rates remain poor. Our case study presents typical features of a rare disease, which can often present a diagnostic dilemma for clinicians.

    The prevalence of genital Chlamydia trachomatis infection and some epidemiologic factors associated with it were studied in 273 pelvic inflammatory disease (PID) patients attending Gynaecologic clinic, Government Medical College, Nagpur. For detection of chlamydial antigen Pharmacia Diagnostics Chlamydia EIA test was used. This study revealed an overall positivity rate of 33% for C. trachomatis infection in PID patients. Of the hypothesised risk factors low socioeconomic status, history of sexual contacts with multiple partners and use of intrauterine devices (IUD) were significantly associated with C. trachomatis infections. However, use of oral contraceptives, barrier contraceptives and increasing age were found to be protective factors for C. trachomatis infection. Thus considering the significant contribution of C. trachomatis in etiology of PID and its independent association with some epidemiologic risk factors, extensive epidemiologic measures are recommended for prevention of these infections.

    A three-year-old male Siberian Husky dog was referred to the Veterinary Teaching Hospital in Osaka Prefecture University with a complaint of difficulty in expelling the stools. By rectal examination, a mass as big as a fist could be detected occupying the cavum pelvis. Radiographically the mass had a thin bony shell bulging from the pubic periosteum. In the shell, radiolucent trabeculation gave the area a "soap bubble" appearance. The cut surface of the removed mass showed a honeycomb-like pattern constituted of some small loculate bony cysts. These cysts were separated from each other by a fibrous or bony trabeculae with blood-filled vascular channels or sponge-like structures. From clinical and pathological findings, this mass was diagnosed as a pelvic aneurysmal bone cyst. After surgery, the patient completely recovered without tenesmus. PMID:9409519

    The Hoffmann external fixator was used to stabilize unstable pelvic fractures in 56 patients with multiple injuries. It was applied under general anaesthesia and the dislocated pelvis reduced and secured with a single tie bar. In 16 cases residual dislocation of less than 1.5 cm was noted after the reduction and the reduced position was maintained in 48 out of 51 cases, a minor redislocation occurred in the remaining 3 patients. Few complications could be attributed to the method, infection was noted in one patient, the iliac crest was fractured in one case and an exostosis of the iliac crest occurred in one youth. Forty-three patients were symptom free with regard to the pelvis at the time of review whereas 5 patients had residual pain and 3 diffuse symptoms. The technique of application is simple but requires two surgeons at the time of reduction and fixation of the pelvis. PMID:528084

  16. Differential diagnosis of acute pelvic inflammatory disease.

    1980-12-01

    Laparoscopic investigations have shown that clinical symptoms and signs in cases of acute pelvic inflammatory disease (acute salpingitis) show considerable variation and seem to a great extent to be nonspecific. Diagnosis based on clinical criteria alone is, therefore, unacceptably unreliable. Different intrapelvic disorders and acute infections limited to the lower genital tract (LGTI) represent substantial differential diagnostic problems. The routine use of laparoscopy is currently the best method for solving these problems but its broader application is restricted by several factors. Determination of specific genital isoamylases obtained at vaginal puncture of the cul-de-sac seems to represent a promising and specific laboratory test for differentiating between acute PID and LGTI that simulates acute PID.

    In the last few decades radiotherapy was established as one of the best and most widely used treatment modalities for certain tumours. Unfortunately that came with a price. As more people with cancer survive longer an ever increasing number of patients are living with the complications of radiotherapy and have become, in certain cases, difficult to manage. Pelvic radiation disease (PRD) can result from ionising radiation-induced damage to surrounding non-cancerous tissues resulting in disruption of normal physiological functions and symptoms such as diarrhoea, tenesmus, incontinence and rectal bleeding. The burden of PRD-related symptoms, which impact on a patient’s quality of life, has been under appreciated and sub-optimally managed. This article serves to promote awareness of PRD and the vast potential there is to improve current service provision and research activities. PMID:26649150

    A 53-year-old woman presented with a 3-month history of left inguinocrural and lumbar pain and anorexia with weight loss. No fever was reported. The patient had no prior pelvic surgery. Physical examination revealed a palpable nontender mass in the left groin area. There was no bloody or purulent discharge. Laboratory findings revealed inflammation with an increased C-reactive protein level (127 mg/L [1209 nmol/L]), leukocytosis (13 800/mm(3)), and microcytic anemia (hemoglobin level, 7.2 g/dL). Computed tomography (CT), fluorine 18 ((18)F) fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT, and magnetic resonance (MR) imaging were performed. PMID:26101924

    1988-07-01

    With only 7 other cases reported throughout history, the incidence of ureteric obstruction is a rare complication of actinomycosis. Diagnosis of pelvic actinomycosis is generally difficult and only confirmed after histological examination. In the case of a 45-year-old caucasian woman who had been complaining of night sweats, epigastric and back pain and constipation, histological examination demonstrated the presence of actinomycosis in both the endometrium and the myometrium. Actinomyces israelli is a gram positive anaerobic parasite that alternates in form between a true bacterium and a complex fungus. The disease is often connected with the presence of a foreign body. It has been theorized that the presence of a foreign body combined with heavy anaerobic vaginal flora provides the perfect setting for actinomycotic growth. This growth is possible with all types of IUDs. Antibiotic therapy initially at a high dosage followed by prolonged oral therapy is generally recommended. However, laparotomy is needed for diagnosis and for the debulking procedure. PMID:3044479

    Pelvic actinomycosis is a granulomatous chronic illness due to anaerobic, gram-positive, branching filamentous bacteria (Actinomyces israelii), this and other species of actinomyces occur in the normal flora of the gastrointestinal and genital tract in humans. Infection is associated in women using an IUD (Intrauterine device) for long periods and it has the characteristic of simulate malignant diseases causing most of the times wrong preoperative diagnosis. We analyzed a postmenopausal patient who was treated surgically without specific diagnosis, then by anatomo-pathologic study of the specimen the result was actinomycosis. The main purpose to obtain the correct preoperative diagnosis is because we have to use antibiotics in the treatment and it may reduce the frequency of radical surgeries. PMID:15002694

    Most women with symptomatic acute pelvic inflammatory disease (PID) are now managed outside of hospital by private practitioners. Clinical diagnosis of PID is often inaccurate, but can be improved by knowledge of risk factors, use of simple investigations, and referral for laparoscopy when the physician is unsure. Prompt treatment with a recommended regimen that includes at least two antibiotics, careful consideration of when to hospitalize or refer, and an awareness of the need for compliance and follow up are important attributes of good management. In contrast, asymptomatic PID, which is a common antecedent of tubal factor infertility and ectopic pregnancy, can be prevented only by screening for and appropriate treatment of sexually transmitted infections.

    Several organic and functional disorders of the urinary bladder, reproductive tract, anorectum, and the pelvic floor musculature cause pelvic pain. This article describes functional disorders in which chronic pelvic and anorectal pain cannot be explained by a structural or other specified pathology. Currently, these functional disorders are classified into urogynecologic conditions or cystitis and painful bladder syndrome, anorectal disorders, and the levator ani syndrome. Although nomenclature suggests that these conditions are distinct, there is considerable overlap of their symptoms and these disorders have much in common. PMID:18794003

    Pelvic organ prolapse repair with mesh remains the gold standard for advanced prolapse. There are several surgical approaches available to the pelvic reconstructive surgeon. Prolapse repair can be performed vaginally or abdominally using native tissue or may be augmented with a biologic or mesh patch. In this article, we will review the different approaches to prolapse repair, the role of mesh, and the risks and benefits of each option. Patient selection, surgical technique, and the rationale for using mesh will be explored. Complications from prolapse repair with mesh including dyspareunia, pelvic pain, mesh exposure, and reoperation will be discussed. PMID:26874532

    We describe pelvic and rectal actinomycosis in a patient with an intrauterine contraceptive device. The presentation was that of an indolent, noninfectious process which mimicked a pelvic malignancy. As in many cases of pelvic actinomycosis, the diagnosis was not suspected preoperatively. Moreover, suppurative disease progressed despite removal of the intrauterine device. In patients who have intrauterine contraceptive devices or who have had them removed recently, abdominal pain, recurrent vaginal bleeding or adnexal masses should prompt a diligent search for potentially pathogenic actinomyces in the genital tract.

    High-energy pelvic ring injuries can represent life-threatening injuries in the polytraumatized patient, particularly when presenting with hemodynamic instability. These injuries mandate a systematic multidisciplinary approach to evaluation, and timely intervention to address hemorrhage while concomitantly addressing mechanical instability. These pelvic injuries are associated with potentially lethal hemorrhage originating from venous, arterial, and osseous sources. A thorough understanding of anatomy, radiographic findings, and initial physical examination can alert one to the presence of pelvic instability necessitating emergent treatment. The focus is on hemorrhage control, using techniques for skeletal stabilization, angiography, and open procedures to decrease mortality in this high-risk patient population. PMID:27241378

    2014-01-01

    Epidemiological studies have shown that lower urinary tract symptoms, including overactive bladder, commonly occur in both men and women, with an age-related increase in both sexes. Vascular endothelial dysfunction and urological symptoms are common in the metabolic syndrome; they also occur during the human ageing process and are independent risk factors for the development of atherosclerosis and hypertension. Pelvic arterial insufficiency may lead to impaired lower urinary tract perfusion and play an important role in the development of bladder dysfunction such as detrusor overactivity and overactive bladder. It seems reasonable, but has not been definitely established clinically, that chronic ischemia-related bladder dysfunction will progress to bladder underactivity. Studies in experimental models in rabbits and rats have shown that pelvic arterial insufficiency may result in significant bladder ischemia with reduced bladder wall oxygen tension, oxidative stress, increased muscarinic receptor activity, ultrastructural damage, and neurodegeneration. Several types of drug may be able to prevent some of these changes. Even if the??1-adrenoceptor blocker, silodosin, the phosphodiesterase type 5 inhibitor, tadalafil, the??3-?1-adrenoceptor agonist, mirabegron, and the free radical scavenger, melatonin, were unable to prevent the development of neointimal hyperplasia and consequent luminal occlusion in animal models, they all exerted a protecting effect on urodynamic parameters, and on the functional and morphological changes of the bladder demonstrable in vitro. The different mechanisms of action of the drugs suggest that many factors are involved in the pathogenesis of chronic ischemia-induced bladder dysfunction and can be targets for intervention. Since several of the agents tested are used clinically and effectively for relieving lower urinary tract symptoms, the results from animal models of chronic bladder ischemia seem to have translational value. Animal models may be of relevance for designing clinical studies to demonstrate if a certain drug may prevent progression of ischemia-related functional and morphological bladder changes.

    The objective of this study was to assess outcome and recurrence rate after limb-salvage surgery with reconstruction for pelvic bone tumors and analyze complications and their relationship with surgery. The authors analyzed 129 patients followed for a mean of 6 years (range, 2-19 years). Chondrosarcoma was the most frequent histotype. Thirty-one cases with no acetabular involvement were reconstructed with allograft only. Acetabular resections were reconstructed with allograft prosthetic composite (n=60), allograft only (n=11), trabecular metal components (n=2), prosthesis only (n=10), saddle prosthesis (n=11), and iliofemoral arthrodesis (n=1). Margins were wide (n=94), wide contaminated (n=22), marginal (n=7), and intralesional (n=6). Oncologic outcomes were as follows: 75 patients were continuously disease free, 6 were disease free after treatment of relapse, 13 were alive with disease, 28 were dead of disease, and 5 were dead of other causes. Survival was 66% at 10 years. Local recurrence rate of malignant tumors was 22.1% and was not statistically influenced by margins (P=.140) or site (P=.933). Metastasis rate was 32.8%. Deep infection was observed in 30 (23.6%) cases, with no statistical difference between reconstructions with and without allograft (P=.09). Final external hemipelvectomy was performed in 16 cases. Newer techniques of reconstruction using stemmed acetabular cups or porous metal components combined with allograft are now available. Local control and satisfactory survival is achievable long term in patients with pelvic tumors, but this surgery implies a high rate of complications. Infection is a major complication, not influenced by the use of allografts. Amputation is rarely needed. PMID:25665107

  10. Doppler echocardiographic analysis of flow in the ductus arteriosus of infants with hypoplastic left heart syndrome: relationship of flow patterns to systemic oxygenation and size of interatrial communication.

    1996-01-01

    Excessive pulmonary overcirculation related to imbalance in the pulmonary/systemic vascular resistance ratio contributes to hemodynamic instability in infants with the hypoplastic left heart syndrome. Because the ductus arteriosus bridges the two vascular circuits in this lesion, we studied the Doppler echocardiographic flow patterns in the ductus arteriosus of 50 infants with hypoplastic left heart syndrome to investigate their relationship to the degree of pulmonary blood flow as measured by simultaneously obtained levels of partial pressure of oxygen in arterial blood. The degree of restriction to pulmonary venous egress as determined by size of the interatrial communication was also correlated with ductal flow patterns and partial pressure of oxygen in arterial blood. Biphasic flow was noted in all infants. Mean peak velocity of antegrade flow (pulmonary artery to aorta) was greater than that of retrograde flow (aorta to pulmonary artery) (131 +/- 45 cm/sec versus 54 +/- 15 cm/sec; p < 0.001), mean time of retrograde flow was greater than that of antegrade flow (246 +/- 60 msec versus 174 +/- 28 msec; p < 0.001), and mean velocity-time integral of antegrade flow was greater than that of retrograde flow (13.3 +/- 4.8 cm versus 6.3 +/- 3.4 cm; p < 0.001). The ratio of velocity-time integral of retrograde flow/antegrade flow (a volumetric estimate of diastolic reversal into the pulmonary vascular bed indexed to systemic output) correlated extremely well with partial pressure of oxygen in arterial blood (r = 0.91; p < 0.0001). Categoric size of the interatrial communication (none, n = 2; small [<2 mm], n = 9; moderate [3 to 4 mm], n = 23; and large [>4 mm], n = 16) correlated with partial pressure of oxygen in arterial blood (r = 0.82; p < 0.001); the smaller the interatrial communication the lower the partial pressure of oxygen in arterial blood and velocity-time integral ratio of retrograde/antegrade flow. Doppler flow patterns in the ductus arteriosus of infants with hypoplastic left heart syndrome are reflective of the resistance ratio between the pulmonary and systemic vascular circuits and may be helpful in monitoring the hemodynamics of these infants.

  11. Ethics versus education: pelvic exams on anesthetized women.

    2005-08-01

    In a survey of junior and senior medical students at the University of Oklahoma, a large majority of respondents reported having performed pelvic exams on anesthetized gynecologic surgery patients. Nearly three-quarters also reported believing that these patients had not specifically consented to undergo exams by students during their surgical procedures. While some students and medical educators maintain that pelvic exams under anesthesia are necessary for the development of students' examination skills, this assertion has not gone unquestioned. Serious ethical concerns have been raised by members of the medical community and women's advocacy groups, and the practice was recently outlawed in one state. Despite this widespread opposition, non-consented pelvic examinations evidently remain a common practice in US teaching hospitals. Our consideration of this controversial issue leads us to conclude that explicit, informed consent must be obtained in order for pelvic examinations to be performed on surgical patients, or risk compromising the doctor-patient relationship.

    Pelvic ring fractures are associated with high rates of mortality and thus can provide key information about circumstances surrounding death. These injuries can be particularly informative in skeletonized remains, yet difficult to diagnose and interpret. This study adapted a clinical system of classifying pelvic ring fractures according to their resultant degree of pelvic stability for application to gross human skeletal remains. The modified Tile criteria were applied to the skeletal remains of 22 individuals from the Cleveland Museum of Natural History and Universidad Nacional Autónoma de México that displayed evidence of pelvic injury. Because these categories are tied directly to clinical assessments concerning the severity and treatment of injuries, this approach can aid in the identification of manner and cause of death, as well as interpretations of possible mechanisms of injury, such as those typical in car-to-pedestrian and motor vehicle accidents.

    Actinomycosis is a chronic, granulomatous, suppurative and fistulasing infection related to a gram-positive bacteria (actinomyces israeli). Cervico-facial actinomycosis is the most common localization. The prevalence of abdomino-pelvic actinomycosis is increasing mainly with the increase of the use of intrauterin device. Its clinical presentation is variable and may mimic cancer or tuberculosis. The diagnosis of abdomino-pelvic actinomycosis is hard and most of the cases are detected during surgical exploration. We report two cases of abdomino-pelvic actinomycosis; in the first case, the disease was extended to the caecum and the abdominal wall. The skin biopsies made the diagnosis of actinomycosis, avoiding surgery. In the second case, the diagnosis of actinomycosis is made post operatively because of high suspicion of pelvic cancer. Through these two observations, we review pathogenesis of the disease, its clinical aspects and its diagnostic and therapeutic means. PMID:15532774

    Pelvic actinomycosis is a rare complication of a long-term intrauterine contraceptive device. Early diagnosis is important, as clinical and radiological imaging may mimic a malignant pathology and lead to radical and unnecessary surgery. We report a case of pelvic actinomycosis in a woman who had used an intrauterine contraceptive device for the last 13 years. The actinomycosis appeared as a malignant pelvic mass with invasion into the sigmoid and left ureter, with high-grade stenosis of these structures. Because of its rapidly developing obstructive character, an urgent Hartmann procedure with resection of the uterus and both ovaries was performed. Histology revealed actinomycosis. With this case we want to illustrate that for a woman presenting with an intrauterine contraceptive device and a malignant appearing mass in the pelvis, pelvic actinomycosis must be considered in the list of differential diagnosis, so that appropriate diagnostic work out and treatment can be made.

    The Vaginal Tactile Imager (VTI) records pressure patterns from vaginal walls under an applied tissue deformation and during pelvic floor muscle contractions. The objective of this study is to validate tactile imaging and muscle contraction parameters (markers) sensitive to the female pelvic floor conditions. Twenty-two women with normal and prolapse conditions were examined by a vaginal tactile imaging probe. We identified 9 parameters which were sensitive to prolapse conditions (p < 0.05 for one-way ANOVA and/or p < 0.05 for t-test with correlation factor r from −0.73 to −0.56). The list of parameters includes pressure, pressure gradient and dynamic pressure response during muscle contraction at identified locations. These parameters may be used for biomechanical characterization of female pelvic floor conditions to support an effective management of pelvic floor prolapse. PMID:26389014

    Pelvic organ prolapse is a vaginal protrusion of female pelvic organs. It has high prevalence worldwide and represents a great burden to the economy. The pathophysiology of pelvic organ prolapse is multifactorial and includes genetic predisposition, aberrant connective tissue, obesity, advancing age, vaginal delivery and other risk factors. Owing to the long course prior to patients becoming symptomatic and ethical questions surrounding human studies, animal models are necessary and useful. These models can mimic different human characteristics – histological, anatomical or hormonal, but none present all of the characteristics at the same time. Major animal models include knockout mice, rats, sheep, rabbits and nonhuman primates. In this article we discuss different animal models and their utility for investigating the natural progression of pelvic organ prolapse pathophysiology and novel treatment approaches. PMID:22707980

    Chronic pelvic pain syndrome (CPPS) is a common problem among men and women worldwide. It is a symptoms-complex term for interstitial cystitis/painful bladder syndrome in women and chronic prostatitis/chronic pelvic pain syndrome in men. Patients often present with a combination of lower urinary tract symptoms with pelvic pain and sexual dysfunction. No gold standard exists for diagnosis or treatment of CPPS. The diagnosis is often challenging and is determined by elimination. Multiple treatment modalities exist, ranging from physical therapy to surgery. We discuss minimally invasive therapies for treatment of this complex of symptoms. Although data suggest reasonable efficacy of several medications, multimodal therapy remains the mainstay of treatment. We review the following minimally invasive therapeutic modalities: dietary modifications, physical therapy, mind-body therapies, medical therapy, intravesical therapies, trigger point injections, botulinum toxin injections to the pelvic floor, and neuromodulation. We report data supporting their use and efficacy and highlight the limitations of each. PMID:20449696

    2008-01-01

    This study is a retrospective multi-centre analysis of changes in spino-pelvic sagittal alignment after surgical correction of L5–S1 developmental spondylolisthesis. The purpose of this study was to determine how sagittal spino-pelvic alignment is affected by surgery, with the hypothesis that surgical correction at the lumbo-sacral level is associated with an improvement in the shape of the spine and in the orientation of the pelvis. Whether L5–S1 high grade spondylolisthesis should or should not be reduced remains a controversial subject. A popular method of treatment has been in situ fusion, but studies have reported a high rate of pseudarthrosis, slip progression and persistent cosmetic deformity. Spinal instrumentation with pedicle screws has generated a renewed interest for reduction, but the indications for this treatment and its effect on spino-pelvic alignment remain poorly defined. Recent evidence indicates that reduction might be indicated for subjects with an unbalanced (retroverted or vertical) pelvis. This is a retrospective multi-centre analysis of 73 subjects (mean age 18 ± 3 years) with developmental spondylolisthesis and an average follow-up of 1.9 years after reduction and posterior fusion with spinal instrumentation or cast immobilisation. Spinal and pelvic alignment were measured on standing lateral digitised X-rays using a computer software allowing a very high inter and intra observer reliability. Pelvic incidence was unaffected by surgery. The most important changes were noted for grade, L5 Incidence, lumbo-sacral-angle, and lumbar lordosis, which all decreased significantly towards normal adult values. At first evaluation, pelvic tilt, sacral slope and thoracic kyphosis appeared minimally affected by surgery. However, after classifying subjects into balanced and unbalanced pelvis, significant improvements were noted in pelvic alignment in both the sub-groups, with 40% of cases switching groups, the majority from an unbalanced to a balanced pelvis alignment. The direction and magnitude of these changes were significantly different by sub-group: sacral slope decreased in the balanced pelvis group but increased in the unbalanced group, while pelvic tilt values did the opposite. While pelvic shape is unaffected by attempts at surgical reduction, proper repositioning of L5 over S1 significantly improves pelvic balance and lumbar shape by decreasing the abnormally high lumbar lordosis and abnormal pelvic retroversion. These results emphasise the importance of sub-dividing subjects with high grade developmental spondylolisthesis into unbalanced and balanced pelvis groups, and further support the contention that reduction techniques might be considered for the unbalanced retroverted pelvis sub-group.

    Until recently, the main indication for pelvic vein embolization (PVE) in women was to treat pelvic venous congestion syndrome (PVC) but increasingly, patients with refluxing pelvic veins associated with leg varicosities are also being treated. A more unusual reason for PVE is to treat pelvic venous malformations, although such lesions may be treated with sclerotherapy alone. Embolotherapy for treating PVC has been performed for many years with several published studies included in this review, whilst an emerging indication for PVE is to treat lower limb varicosities associated with pelvic vein reflux. Neither group, however, has been subjected to an adequate randomized, controlled trial. Consequently, some of the information presented in this review should be considered anecdotal (level III evidence) at this stage, and a satisfactory ‘proof’ of clinical efficacy remains deficient until higher-level evidence is presented. Furthermore, a wide range of techniques not accepted by all are used, and some standardization will be required based on future mandatory prospective studies. Large studies have also clearly shown an unacceptably high recurrence rate of leg varicose veins following venous surgery. Furthermore, minimally or non-invasive imaging is now revealing that there is a refluxing pelvic venous source in a significant percentage of women with de novo leg varicose veins, and many more with recurrent varicosities. Considering that just over half the world’s population is female and a significant number of women not only have pelvic venous reflux, but also have associated leg varicosities, minimally invasive treatment of pelvic venous incompetence will become a common procedure.

    The blueback salmon fingerlings (Oncorhynchus nerka) at the U.S. Fish-Cultural Station at Winthrop, Washington, underwent an infection that was caused by a very short, Gram-positive, nonmotile, rod-shaped bacterium. A further description is impossible at this time, as the organism has not been grown satisfactorily for proper identification. The disease was characterized by white, raised areas of dead tissue mainly in the kidney: for this reason it is referred to as kidney disease. Belding and Merrill (1935) described a disease among the brook, brown, and rainbow trout at a State hatchery in Massachusetts which, from the description, might be the same as kidney disease. J.H. Wales of the California Division of Fish and Game described (unpublished manuscript, 1941) a disease in hatchery trout in California which seems to be identical to kidney disease.

    Pelvic vein incompetence is common in patients with atypical varicose veins, contributing to their recurrence after surgery. Therefore, refluxing pelvic veins should be identified and treated. We present our experience with pelvic vein embolisation in patients presenting with varicose veins. Patients presenting with varicose veins with a duplex-proven contribution from perivulval veins undergo transvaginal duplex sonography (TVUS) to identify refluxing pelvic veins. Those with positive scans undergo embolisation before surgical treatment of their lower limb varicose veins. A total of 218 women (mean age of 46.3 years) were treated. Parity was documented in the first 60 patients, of whom 47 (78.3%) were multiparous, 11 (18.3%) had had one previous pregnancy, and 2 (3.3%) were nulliparous. The left ovarian vein was embolised in 78%, the right internal iliac in 64.7%, the left internal iliac in 56.4%, and the right ovarian vein in 42.2% of patients. At follow-up TVUS, mild reflux only was seen in 16, marked persistent reflux in 6, and new reflux in 3 patients. These 9 women underwent successful repeat embolisation. Two patients experienced pulmonary embolisation of the coils, of whom 1 was asymptomatic and 1 was successfully retrieved; 1 patient had a misplaced coil protruding into the common femoral vein; and 1 patient had perineal thrombophlebitis. The results of our study showed that pelvic venous embolisation by way of a transjugular approach is a safe and effective technique in the treatment of pelvic vein reflux.

  14. Enhanced muscle activity during lumbar extension exercise with pelvic stabilization

    The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seated position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110°, 146°, and 182°. In addition, the trunk extensor muscle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (P<0.05) and the dynamic exercise (P<0.05). These results suggest that the lumbar extension exercise with pelvic stabilization may be more effective for MF and IL muscle activity compared to that without pelvic stabilization. PMID:26730390

  15. Anterior subcutaneous internal fixation for treatment of unstable pelvic fractures

    PubMed Central

    2014-01-01

    Background Fractures of the pelvic ring including disruption of the posterior elements in high-energy trauma have both high morbidity and mortality rates. For some injury pattern part of the initial resuscitation includes either external fixation or plate fixation to close the pelvic ring and decrease blood loss. In certain situations – especially when associated with abdominal trauma and the need to perform laparotomies – both techniques may put the patient at risk of either pintract or deep plate infections. We describe an operative approach to percutaneously close and stabilize the pelvic ring using spinal implants as an internal fixator and report the results in a small series of patients treated with this technique during the resuscitation phase. Findings Four patients were treated by subcutaneous placement of an internal fixator. Screw fixation was carried out by minimally invasive placement of two supra-acetabular iliac screws. Afterwards, a subcutaneous transfixation rod was inserted and attached to the screws after reduction of the pelvic ring. All patients were allowed to fully weight-bear. No losses of reduction or deep infections occurred. Fracture healing was uneventful in all cases. Conclusion Minimally invasive fixation is an alternative technique to stabilize the pelvic ring. The clinical results illustrate that this technique is able to achieve good results in terms of maintenance of reduction the pelvic ring. Also, abdominal surgeries no longer put the patient at risk of infected pins or plates. PMID:24606833

    What is the relationship between the macroscopic parameters of the constitutive equation for a granular soil and the microscopic forces between its grains? How this relationship changes with geometrical properties like the granulometry? In order to investigate these connections we have simulated by molecular dynamics the oedometric compression of a granular soil (a dry and bad-graded sand) and computed the hypoplastic parameters [1] hs (the granular skeleton hardness) and η (the exponent in the compression law) by following exactly the same procedure than in experiments, i.e. by fitting the Bauer's empirical law [2] e/e0= exp(-[3p/hs]η), where p is the vertical stress and e0 and e the initial and present void ratios. Grains are simulated as spheres with normal elastic and dissipative forces plus sliding, pure rolling and static friction between them [3]. Translations and rotations are integrated by using optimized velocity Verlet and Omelyan leap-frog algorithms, respectively. Once a granulometry is fixed, we explore how the two hypoplastic parameters change by modifying the grain stiffness V, the normal damping coefficient γn, and the static μs and dynamic μk friction coefficients. Accumulating all simulations for a fixed granulometry we found, unexpectedly, that the two macroscopic parameters seem to be related by a power law, hs = 0.068(1)η-9.88(3) and, moreover, that the experimental values for a Guamo sand with the same granulometry fits into this power law [4]. Next, we have investigated how this power law changes with granulometry, with increasing number of particles in the simulations and with further experiments on many different sands. The results open interesting questions on the microscopic origin of these constitutive parameters and, moreover, on the origins of Bauer's Law.

    The kidney plays an essential role during excretion of metabolic waste products, maintenance of key homeostasis components such as ion concentrations and hormone levels. It influences the blood pressure, composition and volume. The kidney tubule system is composed of two distinct cell populations: the nephrons forming the filtering units and the collecting duct system derived from the ureteric bud. Nephrons are composed of glomeruli that filter the blood to the Bowman’s capsule and tubular structures that reabsorb and concentrate primary urine. The collecting duct is a Wolffian duct-derived epithelial tube that concentrates and collects urine and transfers it via the renal pelvis into the bladder. The mammalian kidney function depends on the coordinated development of specific cell types within a precise architectural framework. Due to the availability of modern analysis techniques, the kidney has become a model organ defining the paradigm to study organogenesis. As kidney diseases are a problem worldwide, the understanding of mammalian kidney cells is of crucial importance to develop diagnostic tools and novel therapies. This review focuses on how the pattern of renal development is generated, how the inductive signals are regulated and what are their effects on proliferation, differentiation and morphogenesis.

    The aim of this study was to define pelvic floor function in patients with multiple sclerosis and bowel dysfunction, either incontinence (MSI) or defecation difficulties without incontinence (MSC). Normal controls and patients with idiopathic neurogenic faecal incontinence without multiple sclerosis (FI, disease controls) were also studied. Thirty eight multiple sclerosis patients (20 incontinent, 18 incontinent) 73 normal controls, and 91 FI patients were studied. The FI group showed the characteristic combined sensorimotor deficit previously described in these patients of low resting and voluntary contraction and pressures, increased sensory threshold to mucosal stimulation, and increased pudendal nerve terminal motor latencies and fibre densities. MSI patients had significantly lower anal resting pressures (80 (30-140) cm H2O, median (range) v 98 (30-200), normal controls, p = 0.002) and both MSC and MSI patients had significantly lower anal maximum voluntary contraction pressures (65 (0-260) cm H2O, MSC and 25 (0-100), MSI v 120 (30-300), normal controls, p = < 0.0004) and higher external anal sphincter fibre densities (1.7 (1.1-2.6), MSC and 1.7 (1.1-2.4), MSI v 1.5 (1.1-1.75), normal controls, p < 0.006) compared with normal controls but pudendal nerve terminal motor latencies were similar and no sensory deficit was found. This contrasted with the idiopathic faecal incontinent patients who, in addition to significantly higher fibre densities (1.8 (1.1-3), p = 0.001) had increased pudendal latencies (2.5 (1.1-5.5) mS v 2.08 (1.4-2.6), p = 0.001) compared with normal controls. The idiopathic faecal incontinent group had significantly lower resting anal pressures (50 (10-160) cm H2O, p=0.02) than the MSI group. Comparison with the incontinent and continent multiple sclerosis groups showed that incontinence was associated with lower voluntary anal contraction pressures (25 (0-100) v 65 (0-260), p=0.03) but that there were no other differences between these two groups. Pelvic floor function is considerably disturbed in multiple sclerosis, showing muscular weakness with preservation of peripheral motor nerve conduction, providing indirect evidence that this is mainly a result of lesions within the central nervous system.

    The results of the pelvic pouch procedure were reviewed to assess the surgical complication rate and outcome of patients who had had the procedure performed with a stapled ileo-anal anastomosis with and without a defunctioning ileostomy. Between December 1982 and March 1992, 483 patients underwent a pelvic pouch (PP) procedure. Patients were divided into three groups: group I consisted of 325 patients (178 men and boys and 147 women and girls) who underwent a PP procedure with a handsewn ileoanal anastomosis (IAA) with a defunctioning loop ileostomy. In group II, there were 87 patients (47 men and boys and 40 women and girls) who had a stapled IAA with a defunctioning ileostomy. Group III patients consisted of 71 patients (43 men and boys and 28 women and girls) who had a stapled IAA with no covering ileostomy. Assessment was made of the IAA leak rate, the surgical complications, the reoperation rate, and functional outcome. Early surgical complications included 40 (12%) IAA leaks in group I patients compared with only six (7%) leaks in group II patients who had a stapled IAA (p < 0.05). In group III patients, who had a stapled IAA but no covering ileostomy, there were 13 leaks (18%). Eleven of these 13 leaks healed spontaneously with tube drainage; one patient remains with a rectal tube in place 6 weeks after operation, and only one patient has required a reoperation (defunctioning ileostomy). Functionally, all patients with a healed IAA after a leak have had an excellent result comparable to those without a leak. Patients who were male, older than age 40, on steroids, and had had a true one-stage PP procedure, had a greater risk of developing an IAA leak. In two patients, there was intraoperative difficulty, and one of these patients had an IAA leak after operation. Disease activity at the resection margin and patient weight did not affect the leak rate. Our results suggest that the IAA leak rate is significantly reduced in patients with a stapled IAA with an ileostomy compared with those with a handsewn IAA. Omission of the defunctioning ileostomy is associated with a higher IAA leak rate, but spontaneous healing occurs in almost all patients without impairment of functional results. In patients in whom the ileostomy is omitted, the IAA leak rate is greatest in male patients who have undergone a true one-stage PP procedure, are on steroids, and are older than age 40.

    Introduction The sacroiliac joint (SIJ) is frequently involved in low back and pelvic girdle pain. However, morphometrical and functional characteristics related to SIJ pain are poorly defined. Pelvic belts represent one treatment option, but evidence still lacks as to their pain-reducing effects and the mechanisms involved. Addressing these two issues, this case-controlled study compares morphometric, functional and clinical data in SIJ patients and healthy controls and evaluates the effects of short-term pelvic belt application. Methods Morphometric and functional data pertaining to pelvic belt effects were compared in 17 SIJ patients and 17 controls. Lumbar spine and pelvis morphometries were obtained from 3T magnetic resonance imaging. Functional electromyography data of pelvis and leg muscles and center of pressure excursions were measured in one-leg stance. The numerical rating scale was used to evaluate immediate pain-reducing effects. Results Pelvic morphometry was largely unaltered in SIJ patients and also by pelvic belt application. The angle of lumbar lateral flexion was significantly larger in SIJ patients without belt application. Muscle activity and center of pressure were unaffected by SIJ pain or by belt application in one-leg stance. Nine of 17 patients reported decreased pain intensities under moderate belt application, four reported no change and four reported increased pain intensity. For the entire population investigated here, this qualitative description was not confirmed on a statistical significant level. Discussion Minute changes were observed in the alignment of the lumbar spine in the frontal plane in SIJ patients. The potential pain-decreasing effects of pelvic belts could not be attributed to altered muscle activity, pelvic morphometry or body balance in a static short-term application. Long-term belt effects will therefore be of prospective interest. PMID:25781325

    This case report illustrates the dynamic and static renal scintigraphic images of a patient with an unusual large diverticulum of the renal pelvis. The initial diagnosis by intravenous pyelography (IVP) and ultrasonographic (US) examination was a renal pelvic diverticulum of the left kidney, and the patient was referred to the nuclear medicine department for exploration of the effect of the pelvic diverticulum on renal functions. We performed dynamic renal scintigraphy with technetium-99m (Tc-99m) labeled mercaptoacetyl triglycine (MAG-3) and static renal scintigraphy with Tc-99m labeled dimercaptosuccinic acid (DMSA). In dynamic renal scintigraphy, bilaterally normal concentration function was observed. While right kidney excretion function was normal, an incomplete excretion pattern was seen on the left side. Complete urinary flow obstruction occurred approximately at the 10th minute of the acquisition, which did not seem to respond to the i.v. furosemide application. However, when only the renal cortex was included in the region of interest, the obstructive pattern disappeared. In static renal scintigraphy, a large renal pelvic diverticulum localized antero-medially was clearly visualized in the left-anterior oblique projection, most probably due to accumulation of radiopharmaceutical inside it. This case showed that a renal pelvic diverticulum should be thought of when an incomplete excretion pattern is seen on dynamic renal scintigraphy. Using only a cortical region of interest may also help to distinguish other types of obstructive pattern from diverticulum. Additionally, Tc-99m DMSA scintigraphy may show diverticulum localization with antero-oblique projections in addition to routine projections. PMID:15682850

    Insufficiency fractures are a subgroup of stress fractures which occur when normal or physiological stresses are placed on weakened bone. Occurrences of these fractures in the pelvis are difficult to detect clinically and the appropriate radiological investigation is necessary for diagnosis. Osteoporosis is the main underlying cause of these fractures. The clinical and radiological features of three elderly patients with varying presentations of pelvic insufficiency fractures are described. Together with images from three other patients, the radiological spectrum of these fractures is illustrated. The current literature on this subject is reviewed. Plain radiographs are usually unhelpful or may be misleading. Isotope bone scans are the most sensitive modality, demonstrating complete or partial H-shaped sacral uptake, parasymphyseal uptake, or a combination of both. CT is useful for confirming these fractures and excluding malignant disease. Patients invariably improve with bed rest. Awareness of this entity should lead to utilisation of the appropriate imaging modalities for its diagnosis, the proper patient management and avoidance of unnecessary invasive procedures.

    Since the 1993 French consensus conference on uncomplicated pelvic inflammatory diseases (uPID), new antibiotics appeared and bacterial resistances did evoluate. This methodic analysis of the literature updates different aspects of its treatment. Antibiotherapy must be established early (EL3). Inpatient and intravenous treatment is not superior to outpatient and oral treatment (EL1). Ofloxacine+metronidazole association can be proposed in first intention (EL1). If case of Neisseria gonorrhoeae infection, one ceftriaxone injection must be associated (EL4). All the other antibiotics associations have shown to be efficient except the metronidazole+doxycycline association, which is not indicated (EL2). Two weeks treatment seems to be a sufficient duration. Laparoscopic treatment in first intention is not justified except for diagnostic doubts or unfavorable evolution of the medical treatment (EL4). Neither non-steroidic antiinflamatorries, nor corticosteroids, have been proved to be efficient to decrease the adherence risk in uPID (EL3). Early extraction of an intra uterine device (IUD) allows symptomatologic improvement (EL2). Partners treatment with azithromycin improves the 4 months bacteriologic results (EL2). HIV positive patients do not need specific treatment (EL3). PMID:23142353

    Pelvic inflammatory disease (PID) is a common infection in women of reproductive age. However, diagnosis of PID can be difficult due to the wide variation in the symptoms and signs, ranging from subtle or mild symptoms to severe pain in the lower abdomen. Clinical diagnosis alone has only 87% sensitivity and 50% specificity. Therefore, identifying biological factors that are useful for early diagnosis and correlating their expression with the severity of PID could provide significant benefits to women suffering from PID. Pentraxin 3 (PTX3), E-cadherin, myeloperoxidase, stromal cell-derived factor 1 (SDF-1) and the matrix metalloproteinase-9 (MMP-9)/MMP-2 ratio are potential candidates for detecting PID reliably. As PID is often subtle, highly sensitive PID detection methods are needed to promote the prevention of severe sequelae. Growth arrest-specific 6 (Gas6), in combination with its soluble tyrosine kinase receptor, sAxl, could elevate the sensitivity to 92%, which was higher than all other markers tested. Moreover, PTX3, D-dimer and YKL-40 concentrations can predict the clinical course of PID. Although single nucleotide polymorphisms of biomarker genes are not associated with the development of PID, myeloperoxidase SNP -463 G/A and SDF-1 SNP 801 G/A may affect the aggravated expression of their biomarkers in PID.

    The purpose of this report is to describe the case of a 35-year-old patient admitted to the National Oncology Institute in Rabat, Morocco for pelvic pain and deteriorating general status ongoing for 8 months. Clinical and ultrasonographic examination showed a heterogenous mass measuring 7 cm in maximum width located inferior and lateral to the inferior aspect of the right side of the uterus. These findings were suggestive of a malignant tumor of the right ovary. Ovariectomy and omentectomy were performed. Histological examination of surgical specimens demonstrated right tubo-ovarian actinomycosis associated with peritonitis. Genital tract actinomycosis is an uncommon finding in women of childbearing age. It is due to colonization by a pyogenic bacteria (Actinomyces) usually secondary to a gastrointestinal infection, e.g. ileocecum, and sometimes in association with the presence of an intrauterine device or foreign body. Based on this case report, the authors discuss abdominopelvic actinomyocosis with emphasis on tumor-like findings that can lead to misdiagnosis by clinicians and radiologists. PMID:12038184

    The actinomycosis is a chronic suppurative granulomatosis disease. It is owed to a bacillus gram positive; actinomycès israelli. The cervical and thoracic localizations are most frequent. The digestive localization represents 20% of cases. It interest very rarely the pelvis and the genital tracts. We bring back the observation of a patient old of 30 years admitted for mass abdominal. To the exam, the patient had a sensibility of the left hypochondriac area and we found a mass of 6 cm of diameter. To the rectal touch, we found a mass in the bag of Douglas. The echography and the computed tomography revealed a collection under the spleen and a pelvic collection. A rectotomy is performed. The bacteriological study isolates actinomycès israelli. The collection under the spleen is drained under radiological control. Actinomycès israelli is also recovered in the pus brought back by the puncture. The patient is treated by Penicillin. The patient had a favourable evolution. No etiology is found at this patient. For this observation, the collection was accessible to a drainage permitting the diagnosis and the treatment of the actinomycosis while avoiding a mutilated surgery. PMID:12632759

    The established gynecological cancer operations are based on functional anatomy derived from the mature organism and on a model of radial progressive tumor permeation. Surgical treatment aims to resect the tumor with a metrically defined radial margin of tissue microscopically free of neoplastic or dysplastic disease. However, despite adequate surgical performance local tumor relapses still occur. In the presence of histopathological risk factors adjuvant radiation is therefore recommended which increases treatment-related morbidity. The Leipzig School of Radical Pelvic Surgery has developed new gynecological cancer operations from a different perspective on anatomy and local tumor spread. Tissue mapping is deduced by following the organism's development from the stage of tissue deposition to maturity (ontogenetic anatomy) to define permissive compartments for cancer permeation. The variants of mesometrial resection (TMMR, PMMR) and vulva field resection (VFR) achieve very high (>95%) local control rates in stages I and II cancer of the lower and middle female genital tract without adjuvant radiation. Laterally extended endopelvic resection (LEER) provides sustained tumor control even in locally advanced and recurrent disease as well as cancer of the distal vagina. PMID:20628859

    Poor lateral flexor muscle strength can be an important source of lumbar/thoracic back pain in women. The purpose of this study was to evaluate pelvic stabilization (PS) and no pelvic stabilization (NoPS) lateral flexion strength exercise training on the development of isolated right and left lateral flexion strength. Isometric torque of the isolated right and left lateral flexion muscles was measured at two positions (0° and 30° opposed angle range of motion) on 42 healthy women before and after 8 weeks of PS and NoPS lateral flexion strength exercise training. Subjects were assigned in three groups, the first (n=14) trained 3 times/week with PS lateral flexion strength exercise, the second (n=14) trained 3 times/week with NoPS lateral flexion strength exercise and the third (control, n=14) did not train. Post training isometric strength values describing PS and NoPS lateral flexion strength improved in greater extent for the PS lateral flexion strength exercise group and in lesser extent for the NoPS lateral flexion strength exercise group, in both angles (p<0.05) relative to controls. These data indicate that the most effective way of training the spine lateral flexion muscles is PS lateral flexion strength exercises; NoPS lateral flexion strength exercises can be an effective way of training for the spine lateral flexion muscles, if there is no access to PS lateral flexion strength training machines.

    Horseshoe kidney is a fusion anomaly found in approximately one in 400–600 people. Due to vascular and ureteral variations, transplantation with a horseshoe kidney presents a technical challenge. In our case, the isthmus connected the upper poles and contained parenchyma. It consisted of three renal arteries, five veins collected to the inferior vena cava, and two ureters and pyelons. It was implanted en bloc to the left side retroperitoneally. During the early period, cellular and humoral rejection was confirmed and treated. For a urine leak, double J catheters were implanted into both ureters. Later, the first catheter was removed. Subsequently, urinary sepsis developed, necessitating graftectomy. The uncommon anatomy of ureters and antibody-mediated rejection (AMR) may both be factors for a ureter tip necrosis led to an infected urinoma. After other Hungarian authors, we also report a horseshoe kidney transplantation that was technically successful. However, after an adequately treated but severe acute humoral rejection, the patient developed sepsis, and the kidney had to be removed. We conclude that transplantation with horseshoe kidney is technically feasible but may increase the risk for urinary complications and resultant infections. Careful consideration of risk and benefit is advised when a transplant professional is faced with this option. PMID:26120481

    Horseshoe kidney is a fusion anomaly found in approximately one in 400-600 people. Due to vascular and ureteral variations, transplantation with a horseshoe kidney presents a technical challenge. In our case, the isthmus connected the upper poles and contained parenchyma. It consisted of three renal arteries, five veins collected to the inferior vena cava, and two ureters and pyelons. It was implanted en bloc to the left side retroperitoneally. During the early period, cellular and humoral rejection was confirmed and treated. For a urine leak, double J catheters were implanted into both ureters. Later, the first catheter was removed. Subsequently, urinary sepsis developed, necessitating graftectomy. The uncommon anatomy of ureters and antibody-mediated rejection (AMR) may both be factors for a ureter tip necrosis led to an infected urinoma.

    Objectives To describe referred pain patterns provoked from intra-pelvic structures in women with chronic pelvic pain (CPP) persisting after childbirth with the purpose to improve diagnostics and give implications for treatment. Materials and Methods In this descriptive and comparative study 36 parous women with CPP were recruited from a physiotherapy department waiting list and by advertisements in newspapers. A control group of 29 parous women without CPP was consecutively assessed for eligibility from a midwifery surgery. Inclusion criterion for CPP was: moderate pain in the sacral region persisting at least six months after childbirth confirmed by pelvic pain provocation tests. Exclusion criteria in groups with and without CPP were: persistent back or pelvic pain with onset prior to pregnancy, previous back surgery and positive neurological signs. Pain was provoked by palpation of 13 predetermined intra-pelvic anatomical landmarks. The referred pain distribution was expressed in pain drawings and described in pain maps and calculated referred pain areas. Results Pain provoked by palpation of the posterior intra-pelvic landmarks was mostly referred to the sacral region and pain provoked by palpation of the ischial and pubic bones was mostly referred to the groin and pubic regions, with or without pain referred down the ipsilateral leg. The average pain distribution area provoked by palpation of all 13 anatomical landmarks was 30.3 mm² (19.2 to 53.7) in women with CPP as compared to 3.2 mm² (1.0 to 5.1) in women without CPP, p< 0.0001. Conclusions Referred pain patterns provoked from intra-pelvic landmarks in women with CPP are consistent with sclerotomal sensory innervation. Magnification of referred pain patterns indicates allodynia and central sensitization. The results suggest that pain mapping can be used to evaluate and confirm the pain experience among women with CPP and contribute to diagnosis. PMID:25793999

    PubMed Central

    2014-01-01

    Encephalopathy and altered higher mental functions are common clinical complications of acute kidney injury. Although sepsis is a major triggering factor, acute kidney injury predisposes to confusion by causing generalised inflammation, leading to increased permeability of the blood–brain barrier, exacerbated by hyperosmolarity and metabolic acidosis due to the retention of products of nitrogen metabolism potentially resulting in increased brain water content. Downregulation of cell membrane transporters predisposes to alterations in neurotransmitter secretion and uptake, coupled with drug accumulation increasing the risk of encephalopathy. On the other hand, acute brain injury can induce a variety of changes in renal function ranging from altered function and electrolyte imbalances to inflammatory changes in brain death kidney donors.

    2015-09-01

    Pelvic floor dysfunction is a growingly frequent condition in aging individuals. Urinary or rectal incontinence, constipation, pelvic organ prolapse, pelvic pain or sexual dysfunction are common problems in this age range. Such conditions carry a severe impact on quality of life, but also limit individual independence in daily activities, favor social isolation and carry health risks. Diagnosis and treatment of pelvic floor dysfunction in aging women is tricky, since multiple interfering conditions affecting muscle tone and nerve function are common in these individuals. Diabetes mellitus, sarcopenia, use of drugs that affect cognition or impact bowel or urinary function are just a few examples. These conditions need to be thoroughly taken into account during pre-operative work up for their potential impact on the success of surgery and vice versa. Functional reconstruction aimed at treating symptoms rather than anatomic defects is key to success. The recent advancements in surgical treatment of urinary incontinence and pelvic organ prolapse allow for more options to achieve the best surgery in each patient. PMID:26142653

    A normal motion and segmental interrelationship has been determined as a significant factor in normal function. Yet, the relationship between distal segments and pelvic alignment needs further investigation. The aim of this study was to investigate the interrelationship between distal and proximal lower extremity segments while standing and during induced feet hyperpronation. Changes in alignment of the pelvis and lower extremities were measured at a gait laboratory using the VICON 612 computerized motion analysis system. Thirty-five healthy volunteer subjects were recruited. Four randomized repeated-measure standing modes were used: standing directly on the floor and then on three wedges angled at 10°, 15° and 20° to induce bilateral hyperpronation for 20 seconds. A significant (p<0.05) bi-variate relationship was found between the anterior pelvic tilt and thigh internal rotation, in all four standing positions (.41≤r≤.46, in all p<0.014). A combined effect of rotational alignment between segments and the cumulative effect of foot hyperpronation on pelvic tilt revealed that only the shank significantly affected pelvic alignment, acting as a mediator between a foot and a thigh with the thigh having a crude significant effect on the pelvis. When internal rotation of the shank occurs, calcaneal eversion couples with thigh internal rotation and anterior pelvic tilt. It can be concluded that in response to induced hyperpronation, the shank is a pivotal segment in postural adjustment. PMID:26240652

    Objective To assess prenatal counseling practices of obstetrical providers related to postpartum pelvic floor dysfunction at centers with integrated urogynecology services. Study Design A cross-sectional survey was distributed to obstetrical providers through urogynecology colleagues. The survey included questions about level of training as well as counseling practices related to common postpartum pelvic floor symptoms. All statistical tests were two sided, and P values <0.05 were considered statistically significant. Results One hundred ninety-two surveys were received; 19 respondents did not perform their own prenatal counseling and were excluded. Among the remaining 173 respondents, 94 (56.3%) of those who answered the question reported never discussing postpartum urinary incontinence, and 73.7% reported never discussing postpartum fecal incontinence during prenatal counseling. Obstetrics and gynecology residents were significantly less likely than attending physicians to report discussing various pelvic floor dysfunction topics in prenatal counseling. Among those who reported not counseling women regarding pelvic floor dysfunction, the most common reason cited was lack of time (39.9%) followed by lack of sufficient information (30.1%). Conclusion Prenatal counseling of pelvic floor dysfunction risk is lacking at all levels of obstetrical training. Limitations of time and information are the obstacles most often cited by providers.

    ABSTRACT Objective: The purpose of this study was to assess the importance of pelvic fractures in childhood by analyzing epidemiological characteristics and associated injuries. Methods: This is a retrospective study performed between 2002 and 2012 at two trauma referral centers in São Paulo. We identified 25 patients aged 16 years old or younger with pelvic fracture. Results: The main mechanism of trauma was traffic accident (80%), followed by fall from height (16%). At hospital admission, 92% had traumatic brain injury and 40% had hemodynamic instability. Besides pelvic fractures, 56% of the children had other associated injuries (genitourinary, abdominal, vascular, chest and neurological), and 79% of them required operative treatment. According to the Torode and Zieg classification, the majority of cases were types III and IV. Seventy-two percent of all pelvic fractures were treated by surgery; 52% involved external fixation and 20% involved open reduction and internal fixation. Conclusions: The pelvic fractures in childhood can be considered a marker for injury severity, because the associated injuries usually are severe, needing operative treatment and leading to a high mortality rate (12%).

  1. Common Questions About the Evaluation of Acute Pelvic Pain.

    PubMed

    2016-01-01

    Acute pelvic pain is defined as lower abdominal or pelvic pain of less than three months' duration. It is a common presentation in primary care. Evaluation can be challenging because of a broad differential diagnosis and because many associated signs and symptoms are nonspecific. The most common diagnoses in reproductive-aged women with acute pelvic pain are idiopathic pelvic pain, pelvic inflammatory disease, acute appendicitis, ovarian cysts, ectopic pregnancy, and endometriosis. Among postmenopausal women, cancer must be considered. Findings from the history and physical examination can point to likely diagnoses, and laboratory testing and imaging can help confirm. Women of reproductive age should take a pregnancy test. In early pregnancy, transvaginal ultrasonography and beta human chorionic gonadotropin levels can help identify ectopic pregnancy and spontaneous abortion. For nonpregnant women, ultrasonography or computed tomography is indicated, depending on the possible diagnosis (e.g., ultrasonography is preferred when ovarian pathology is suspected). If ultrasonography results are nondiagnostic, magnetic resonance imaging can be helpful in pregnant women when acute appendicitis is suspected. If magnetic resonance imaging is unavailable, computed tomography may be indicated. PMID:26760839

    2016-02-01

    Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g., women's health or urology nurse practitioner (NP), physical therapist (PT)) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence-based research indicating the efficacy and cost-effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first-line treatment in clinical practice in the USA (Abrams et al., 2012). This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA. PMID:26757904

    Purpose: To assess the incidence, predisposing factors, and clinical characteristics of insufficiency fractures (IF) in patients with prostate cancer, who received pelvic radiotherapy as part of their definitive treatment. Methods and Materials: The charts of 134 prostate cancer patients, who were treated with pelvic radiotherapy between 1998 and 2007 were retrospectively reviewed. IF was diagnosed by bone scan and/or CT and/or MRI. The cumulative incidence of symptomatic IF was estimated by actuarial methods. Results: Eight patients were identified with symptomatic IF after a median follow-up period of 68 months (range, 12-116 months). The 5-year cumulative incidence of symptomatic IF was 6.8%. All patients presented with lower back pain. Insufficiency fracture developed at a median time of 20 months after the end of radiotherapy and was managed conservatively without any need for hospitalization. Three patients were thought to have metastatic disease because of increased uptake in their bone scans. However, subsequent CT and MR imaging revealed characteristic changes of IF, avoiding any further intervention. No predisposing factors for development of IF could be identified. Conclusions: Pelvic IF is a rare complication of pelvic radiotherapy in prostate cancer. Knowledge of pelvic IF is essential to rule out metastatic disease and prevent unnecessary treatment, especially in a patient cohort with high-risk features for distant spread.

    2013-01-01

    Purpose of review Pelvic floor disorders affect women of all ages and are associated with significant economic burden and poor quality of life. Current literature suggests an association between childbirth and these disorders. In this review, we summarize recent advancements in our understanding of this association. Recent findings Vaginal childbirth appears to be strongly associated with stress urinary incontinence and pelvic organ prolapse. There is less evidence to suggest an association between vaginal delivery and overactive bladder symptoms. History of more than one perineal laceration increases the likelihood of developing prolapse. Similar association has not been established for episiotomy. Disruption or denervation of structural components of pelvic floor support system, particularly levator ani muscle complex, is associated with later development of pelvic floor disorders. Imbalance in homeostasis of connective tissue remodeling of the vaginal wall from overstretching during childbirth is another possible mechanism. Summary Pelvic floor disorders represent a significant health problem affecting women of all ages. Identification of potential modifiable risk factors and advancement in understanding of the underlying pathophysiology is crucial for primary and secondary prevention of these disorders and for improvement in treatment strategies.

    In this paper, we present a fully automated localization method for multiple pelvic bone structures on magnetic resonance images (MRI). Pelvic bone structures are at present identified manually on MRI to locate reference points for measurement and evaluation of pelvic organ prolapse (POP). Given that this is a time-consuming and subjective procedure, there is a need to localize pelvic bone structures automatically. However, bone structures are not easily differentiable from soft tissue on MRI as their pixel intensities tend to be very similar. In this paper, we present a model that combines support vector machines and nonlinear regression capturing global and local information to automatically identify the bounding boxes of bone structures on MRI. The model identifies the location of the pelvic bone structures by establishing the association between their relative locations and using local information such as texture features. Results show that the proposed method is able to locate the bone structures of interest accurately (dice similarity index >0.75) in 87-91% of the images. This research aims to enable accurate, consistent, and fully automated localization of bone structures on MRI to facilitate and improve the diagnosis of health conditions such as female POP.

    Obesity is a major global health concern affecting all ages, socioeconomic groups, and countries. Although men have higher rates of overweight, women have higher rates of obesity. In the United States, more than 60% of women are overweight or obese, with slightly more than one-third considered frankly obese. Obesity is a major risk factor for noncommunicable diseases such as diabetes mellitus, cardiovascular disease, hypertension, stroke, and specific cancers. Obesity is associated with increased mortality for all cancers, with the highest death rates occurring in the heaviest women. Obesity can contribute to missed diagnoses, nondiagnostic results of imaging studies, imaging examination cancellation because of weight or girth restrictions, scheduling of inappropriate examinations, and increased radiation dose exposure. The utility of the clinical examination is often limited in the obese woman, which results in an even greater reliance on imaging; however, the obese woman may experience a lowered quality of and less access to medical imaging. Recognition of equipment limitations, imaging artifacts, optimization techniques, and appropriateness of modality choices is critical to providing good patient care to this health-challenged group. The clinical indication, the patient's weight, and the body diameters are three key factors to consider when choosing the most appropriate examination. Familiarity with the optimization of imaging techniques across all modalities is important to convert potentially suboptimal examinations into diagnostic-quality studies. The aim of this review is to identify key areas in which obesity affects the imaging care of women with pelvic conditions and to outline strategies to address these areas. PMID:23065172

    2015-02-01

    Chronic pelvic pain (CPP) affects 24% of women worldwide; the cause cannot be identified in 40% despite invasive investigations. Dilated, refluxing pelvic veins may be a cause of CPP and treatment by trans-venous occlusion is increasingly performed when gynecological causes are excluded, but is it effective? A systematic review of the literature published between 1966 and July 2014 was conducted. Two authors independently reviewed potential studies according to a set of eligibility criteria, with a third assessor available as an arbiter. Thirteen studies including 866 women undergoing trans-venous occlusion of pelvic veins for CPP were identified (Level of evidence: one study grade 2b, 12 studies grade four). Statistical significant improvements in pelvic pain were reported in nine of the 13 studies. Technical success was reported in 865 of 866 (99.8%) with low complication rates: coil migration in 14 women (1.6%), abdominal pain in ten women (1.2%) and vein perforation in five (0.6%). In a study on varicose veins of the legs, recurrence was seen in 13% of 179 women 5-years following coil embolization. Subjective improvements in pain were seen in all 13 studies after treatment by trans-venous occlusion. All 13 studies were of poor methodological quality. Complication rates were low and no fatalities occurred. Well-designed studies are essential to determine whether pelvic vein incompetence (PVI) is associated with CPP, and to explore whether trans-venous occlusion of PVI improves quality of life for these women.

    The occurrence of pelvic insufficiency fractures in patients with rheumatoid arthritis has not previously been well emphasized. These fractures are difficult to detect clinically, and appropriate radiological investigation is necessary for diagnosis. A 72-year-old woman with rheumatoid arthritis presented with severe left groin pain. Pelvic radiographs showed parasymphyseal fractures, and marked instability of these fractures was observed at the follow-up 2 weeks later. Computed tomographic scan of the sacrum showed a widened linear fracture gap in the left sacral ala. Because the patient's pain was so severe that she could not change position, external fixation was performed to achieve rapid pain relief and early mobilization. Although most patients with these fractures respond well to simple conservative treatments, parasymphyseal fractures combined with sacral fractures may cause disruption of the pelvic ring and occasionally need operative management.

    Acute pelvic pain in women is a common reason for emergency department admission. There is a broad range of possible aetiological diagnoses, with gynaecological and gastrointestinal causes being the most frequently encountered. Gynaecological causes include upper genital tract infection and three types of surgical emergency, namely ectopic pregnancy, adnexal torsion, and haemorrhagic ovarian cyst rupture. The main gastrointestinal cause is acute appendicitis, which is the primary differential diagnosis for acute pelvic pain of gynaecological origin. The process of diagnosis will be guided by the clinical examination, laboratory study results, and ultrasonography findings, with suprapubic transvaginal pelvic ultrasonography as the first-line examination in this young population, and potentially cross-sectional imaging findings (computed tomography and MR imaging) if diagnosis remains uncertain.

    Background: To determine the role of Letrozole, an aromatase inhibitor, in the treatment of endometriotic pain. Methods: In this prospective, randomized, controlled clinical trial in minimally invasive surgery research center, 51 women with pelvic endometriosis and endometriotic pain (dyspareunia, dysmenorrhea, pelvic pain) score of 5 or more (for at least one of these endometriotic pain), after laparoscopic diagnosis and conservative laparoscopic surgery were treated with either Letrozole plus OCP (n=25) or only OCP (n=26) for 4 months continuously. Results: Using VAS test, the score of dyspareunia, dysmenorrhea and pelvic pain 4 months after the laparoscopic surgery declined significantly in both groups but the difference between results of the two groups was not significant. Conclusion: Both treatment modalities showed comparable effectiveness in the treatment of pains related to endometriosis and in comparison with OCP, Letrozole did not affect the outcome.

    Chronic pelvic pain in men has often been misdiagnosed as prostatitis. After excluding serious or acute urological, neurological or colorectal conditions, it is essential to approach these patients with a much more comprehensive criteria. Thoughtful interview and methodical physical examination can very often reveal pelvic floor muscle dysfunction, Myofascial pain syndromes, Functional Somatic Syndrome/Central Sensitization Syndromes and/or psychosocial distress. One must be aware that many of these syndromes frequently overlap. Acknowledgement of these conditions and validation of both their physical and psychological distress is paramount to creating trust and confidence in the patient. These are the cornerstones for empowerment and self-care required in the management of chronic pelvic pain. PMID:26717951

    Background The purpose of this work was to investigate whether clinical cytology could be useful in the preoperative diagnosis of pelvic actinomycosis. Methods This study involved the prospective collection of samples derived from the endometrium and the uterine cervix, and retrospective data analysis. Nine patients with clinically diagnosed pelvic actinomycosis were enrolled. The clinical and hematological characteristics of patients were recorded, and detection of actinomyces was performed by cytology, pathology, and bacteriological culture of samples and by imprint intrauterine contraceptive device (IUD) cytology. Results The detection rate of actinomyces was 77.7% by combined cervical and endometrial cytology, 50.0% by pathology, and 11.1% by bacterial culture. Conclusion The higher detection rate of actinomyces by cytology than by pathology or bacteriology suggests that careful cytological examination may be clinically useful in the preoperative diagnosis of pelvic actinomycosis.

  20. Vaginal weights for assessment and training of the pelvic floor.

    PubMed

    Perkins, J

    1998-07-01

    Urinary incontinence is a common problem for women. A trial of conservative treatment is frequently suggested before considering other treatment options. One method involves the use of vaginal weights for retraining the pelvic floor muscle. This review examines articles and abstracts on vaginal weights published in English or with abstracts in English between 1985 and 1997. It concludes that, despite some practical and theoretic concerns, there is adequate clinical evidence to support the use of weights in selected populations. Weights may be an effective training aid for women with mild to moderate stress incontinence, particularly in the absence of severe pelvic organ prolapse. They also may be useful for pelvic floor strengthening during the immediate postpartum period, as a behavioral program for continence maintenance, and for self-management programs. Suggestions for further research to refine treatment parameters and client selection are also presented. PMID:9791381

    Background: Pelvic lymph node metastasis (LNM) is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75–80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs), unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA–IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People's Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI), depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases). Pelvic LNM (P = 0.00) was significantly correlated with recurrence. Pelvic LNM (P = 0.00), the number of positive pelvic LNs (P = 0.04) and a single group versus multiple groups of pelvic LNM (P = 0.03) had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00), depth of cervical stromal invasion (P = 0.00) and parametrial invasion (P = 0.03) were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma. LVSI, parametrial invasion, and depth of cervical stromal invasion were identified as independent clinicopathological risk factors for pelvic LNM. PMID:26228223

    Research has suggested that athletes involved in high-intensity sports for sustained periods have a higher probability of experiencing prolonged second stage of labour compared to non-athletes. The mechanism responsible for this complication is unknown but may depend on the relative size or tone of the pelvic floor muscles. Prolonged training can result in enlargement and stiffening of these muscles, providing increased resistance as the fetal head descends through the birth canal during a vaginal birth. On the other hand, recent studies have suggested an association between increased muscle bulk in athletes and higher distensibility. This project aims to use mathematical modelling to study the relationship between the size and tone of the pelvic floor muscles and the level of difficulty during childbirth. We obtained sets of magnetic resonance (MR) images of the pelvic floor region for a female athlete and a female non-athlete. Thirteen components of the pelvic floor were segmented and used to generate finite element (FE) models. The fetal head data was obtained by laser scanning a skull replica and a FE model was fitted to these data. We used contact mechanics to simulate the motion of the fetal head moving through the pelvic floor, constructed from the non-athlete data. A maximum stretch ratio of 3.2 was induced in the muscle at the left lateral attachment point to the pubis. We plan to further improve our modelling framework to include active muscle contraction and fetal head rotations in order to address the hypotheses that there is a correlation between the level of difficulty and the size or tone of the pelvic floor muscles.

  11. Hypomagnesaemia in kidney transplantation.

    2015-07-01

    In the era of calcineurin inhibitors, hypomagnesaemia is a very common finding in kidney transplant recipients. Especially the first weeks after transplantation it is the rule rather than the exception. Hypomagnesaemia or low magnesium intake have been associated with a higher mortality or more cardiovascular events in the general population, but this association has never been explored in kidney transplant recipients, despite their increased cardiovascular risk. Kidney transplant recipients with pre- or post-transplant hypomagnesaemia seem to have an aberrant glucose metabolism and develop diabetes mellitus more frequently. Moreover, observations from alternate study populations, animal experiments or in vitro studies suggest a possible role of magnesium deficiency in graft dysfunction, bone metabolism and transplant immunology. Future observational and especially interventional studies should further define whether and to what extent we should make effort to correct this electrolyte disturbance in transplant recipients. Considering the mechanism of renal magnesium wasting, normalizing the serum magnesium concentration by oral supplementation alone might turn out to be cumbersome in kidney transplant recipients.

    MicroRNAs, activated by the enzyme Dicer1, control post-transcriptional gene expression. Dicer1 has important roles in the epithelium during nephrogenesis, but its function in stromal cells during kidney development is unknown. To study this, we inactivated Dicer1 in renal stromal cells. This resulted in hypoplastic kidneys, abnormal differentiation of the nephron tubule and vasculature, and perinatal mortality. In mutant kidneys, genes involved in stromal cell migration and activation were suppressed as were those involved in epithelial and endothelial differentiation and maturation. Consistently, polarity of the proximal tubule was incorrect, distal tubule differentiation was diminished, and elongation of Henle's loop attenuated resulting in lack of inner medulla and papilla in stroma-specific Dicer1 mutants. Glomerular maturation and capillary loop formation were abnormal, whereas peritubular capillaries, with enhanced branching and increased diameter, formed later. In Dicer1-null renal stromal cells, expression of factors associated with migration, proliferation, and morphogenic functions including α-smooth muscle actin, integrin-α8, -β1, and the WNT pathway transcriptional regulator LEF1 were reduced. Dicer1 mutation in stroma led to loss of expression of distinct microRNAs. Of these, miR-214, -199a-5p, and -199a-3p regulate stromal cell functions ex vivo, including WNT pathway activation, migration, and proliferation. Thus, Dicer1 activity in the renal stromal compartment regulates critical stromal cell functions that, in turn, regulate differentiation of the nephron and vasculature during nephrogenesis.

    SUMMARY The treatment of chronic pelvic pain in both females and males is a challenge for pain clinicians. Standard therapies are multimodal in nature with use of behavioral, medical and procedural therapeutics. In recent years, our understanding of the neuro biology of this disorder has improved and novel approaches have focused on neuro modulatory options, novel pharmacology and complementary/alternative medicine options. This review briefly examines newly employed therapeutic options, while restating currently utilized options. The current state-of-the-art treatment includes focal therapies for identified pathologies and empiric trials of other options for care when precise sources of the chronic pelvic pain are ill defined.

    We report the case of a Lebanese infant born by normal delivery at 40 weeks of gestation. Weight and height at birth were 3200 grams and 49 cm respectively. Serum creatinine in the first week of life was 323 mmol/l (normal value for age is less than 20 mmol/l). Kidney ultrasound confirmed diagnosis of hypoplastic small kidneys. Conservative treatment of renal failure was initiated from the first days of life. Conservative management of renal failure included careful attention to fluid balance, maintenance of adequate nutrition and correction of hyperkalemia, acidosis, hyperphosphatemia and prevention of renal osteodystrophy by the use of dietary phosphate binders and vitamin D analogs. After a slight decrease of serum creatinine in the first three months of life, creatininemia increased progressively despite conservative treatment associated to hyperkalemia and severe pruritis due to hyperphosphatemia. Faced with the progression of renal failure, we decided to start automated peritoneal dialysis at seven months of life. Weight and height were respectively 6200 g and 63 cm. Serum creatinine was 432 mmol/L. Pruritis improved after starting peritoneal dialysis as well as appetite. At 20 months of life and a weight of 9.7 kg, a familial kidney transplant was performed. Immunosuppressive treatment included SimulectO, on day 1 and day 4, associated to mycophenolate mofetil, tacrolymus and prednisolone. The immediate post-transplant period was complicated by urinay tract infection due to BSLE E. coli. After four episodes of urinary tract infection due to resistant E coli associated to a non obstructive stone of 15 mm in the allograft kidney, we performed two sessions of lithotripsy and placed a double J stent. Biochemical urinary analysis did not reveal any causes for lithiasis. Stone disappeared as well as infection after lithotripsy. Renal function is normal for age one year after the kidney transplant. To our knowledge, this is the first reported case of a successful kidney transplant in a Lebanese infant with kidney failure since birth with kidney transplant performed at less than 10 kg of weight on the transplant day. Peritoneal dialysis is the treatment of choice for infants with chronic kidney failure. Familial or cadaveric kidney transplant should be encouraged and performed even in infants weighing less than 10 kg allowing them to have normal growth as well as social and school integration.

    Standard initial assessment via ultrasound of a 4-year-old girl with hypertension revealed the absence of one kidney. Instead of cross-sectional imaging of the retroperitoneal space, a functional (nuclear) study was performed. This revealed a malformed kidney within the chest. Though systemic levels of renin and aldosterone were not elevated, removal of the malformed kidney normalized the blood pressure. The presence of prominent smooth muscle nodules surrounding the arteries was seen in the malformed kidney. Initial attempts to avert surgery by pharmacologically reducing blood flow to the malformed kidney were unsuccessful. The review of the literature offers little evidence to support such a strategy.

    Background. Endocardial fibroelastosis (EFE), characterized by a diffuse endocardial thickening through collagen and elastin fibers, develops in the human fetal heart restricting growth of the left ventricle (LV). Recent advances in fetal imaging indicate that EFE development is directly associated with a distended, poorly contractile LV in evolving hypoplastic left heart syndrome (HLHS). In this study, we developed an animal model of EFE by introducing this human fetal LV morphopathology to an immature rat heart. Methods and Results. A neonatal donor heart, in which aortic regurgitation (AR) was created, was heterotopically transplanted into a recipient adult rat. AR successfully induced the LV morphology of evolving HLHS in the transplanted donor hearts, which resulted in the development of significant EFE covering the entire LV cavity within two weeks postoperatively. In contrast, posttransplants with a competent aortic valve displayed unloaded LVs with a trace of EFE. Conclusions. We could show that distention of the immature LV in combination with stagnant flow triggers EFE development in this animal model. This model would serve as a robust tool to develop therapeutic strategies to treat EFE while providing insight into its pathogenesis. PMID:26064914

    Hypoplastic left heart (HLH) occurs in at least 1 in 10 000 live births but may be more common in utero. Its causes are poorly understood but a number of affected cases are associated with chromosomal abnormalities. We set out to localize the breakpoints in a patient with sporadic HLH and a de novo translocation. Initial studies showed that the apparently simple 1q41;3q27.1 translocation was actually combined with a 4-Mb inversion, also de novo, of material within 1q41. We therefore localized all four breakpoints and found that no known transcription units were disrupted. However we present a case, based on functional considerations, synteny and position of highly conserved non-coding sequence elements, and the heterozygous Prox1(+/-) mouse phenotype (ventricular hypoplasia), for the involvement of dysregulation of the PROX1 gene in the aetiology of HLH in this case. Accordingly, we show that the spatial expression pattern of PROX1 in the developing human heart is consistent with a role in cardiac development. We suggest that dysregulation of PROX1 gene expression due to separation from its conserved upstream elements is likely to have caused the heart defects observed in this patient, and that PROX1 should be considered as a potential candidate gene for other cases of HLH. The relevance of another breakpoint separating the cardiac gene ESRRG from a conserved downstream element is also discussed. PMID:19471316

    Previous studies have employed generic 3D-multiscale models to predict haemodynamic effects of the hybrid procedure in hypoplastic left heart syndrome. Patient-specific models, derived from image data, may allow a more clinically relevant model. However, such models require long computation times and employ internal pulmonary artery band [dint] dimension, which limits clinical application. Simpler, zero-dimensional models utilize external PAB diameters [dext] and provide rapid analysis, which may better guide intervention. This study compared 0-D and 3-D modelling from a single patient dataset and investigated the relationship dint versus dext and hemodynamic outputs of the two models. Optimum oxygen delivery defined at dint=2mm corresponded to dext=3.1 mm and 3.4 mm when models were matched for cardiac output or systemic pressure, respectively. 0-D and 3-D models when matched for PAB dimension produced close equivalence of hemodynamics and ventricular energetics. From this study we conclude that 0-D model can provide a valid alternative to 3D-multiscale in the hybrid-HLHS circulation. PMID:25301246

    Kidney disease is a worldwide public health problem. Renal failure follows several disease stages including acute and chronic kidney symptoms. Acute kidney injury (AKI) may lead to chronic kidney disease (CKD), which can progress to end-stage renal disease (ESRD) with a mortality rate. Current treatment options are limited to dialysis and kidney transplantation; however, problems such as donor organ shortage, graft failure and numerous complications remain a concern. To address this issue, cell-based approaches using tissue engineering (TE) and regenerative medicine (RM) may provide attractive approaches to replace the damaged kidney cells with functional renal specific cells, leading to restoration of normal kidney functions. While development of renal tissue engineering is in a steady state due to the complex composition and highly regulated functionality of the kidney, cell therapy using stem cells and primary kidney cells has demonstrated promising therapeutic outcomes in terms of restoration of renal functions in AKI and CKD. In this review, basic components needed for successful renal kidney engineering are discussed, and recent TE and RM approaches to treatment of specific kidney diseases will be presented.

    Anorexia nervosa is a common psychiatric disorder that disproportionately affects adolescents and young adults and is associated with high rates of morbidity and mortality. Anorexia nervosa can affect the kidney in numerous ways, including increased rates of acute kidney injury and chronic kidney disease, electrolyte abnormalities, and nephrolithiasis. Additionally, the diagnosis and treatment of anorexia nervosa-associated kidney diseases are challenging, reflecting complications such as refeeding syndrome, as well as the limitations of serum creatinine level in this population to estimate kidney function and the psychosocial challenges inherent with treating systemic manifestations of psychiatric conditions. In this review, we discuss kidney diseases and kidney-associated conditions that occur in individuals with anorexia nervosa, summarizing many of the challenges in treating patients with this disease.

    2016-01-01

    Fishes have adapted a number of different behaviors to move out of the water, but none have been described as being able to walk on land with a tetrapod-like gait. Here we show that the blind cavefish Cryptotora thamicola walks and climbs waterfalls with a salamander-like diagonal-couplets lateral sequence gait and has evolved a robust pelvic girdle that shares morphological features associated with terrestrial vertebrates. In all other fishes, the pelvic bones are suspended in a muscular sling or loosely attached to the pectoral girdle anteriorly. In contrast, the pelvic girdle of Cryptotora is a large, broad puboischiadic plate that is joined to the iliac process of a hypertrophied sacral rib; fusion of these bones in tetrapods creates an acetabulum. The vertebral column in the sacral area has large anterior and posterior zygapophyses, transverse processes, and broad neural spines, all of which are associated with terrestrial organisms. The diagonal-couplet lateral sequence gait was accomplished by rotation of the pectoral and pelvic girdles creating a standing wave of the axial body. These findings are significant because they represent the first example of behavioural and morphological adaptation in an extant fish that converges on the tetrapodal walking behaviour and morphology.

    2015-02-01

    Female pelvic medicine and reconstructive surgery (FPMRS) was recently recognized as a subspecialty by the American Board of Medical Specialties (ABMS). FPMRS treats female pelvic disorders (FPD) including pelvic organ prolapse (POP), urinary incontinence (UI), fecal incontinence (FI), lower urinary tract symptoms (LUTS), lower urinary tract infections (UTI), pelvic pain, and female sexual dysfunction (FSD). These conditions affect large numbers of individuals, resulting in significant patient, societal, medical, and financial burdens. Given that treatments utilize both medical and surgical approaches, areas of research in FPD necessarily cover a gamut of topics, ranging from mechanistically driven basic science research to randomized controlled trials. While basic science research is slow to impact clinical care, transformational changes in a field occur through basic investigations. On the other hand, clinical research yields incremental changes to clinical care. Basic research intends to change understanding whereas clinical research intends to change practice. However, the best approach is to incorporate both basic and clinical research into a translational program which makes new discoveries and effects positive changes to clinical practice. This review examines current research in FPD, with focus on translational potential, and ponders the future of FPD research. With a goal of improving the care and outcomes in patients with FPD, a strategic collaboration of stakeholders (patients, advocacy groups, physicians, researchers, professional medical associations, legislators, governmental biomedical research agencies, pharmaceutical companies, and medical device companies) is an absolute requirement in order to generate funding needed for FPD translational research.

    2015-03-01

    Synthetic meshes are widely used for surgical repair of different kind of prolapses. In the light of the experience of abdominal wall repair, similar prostheses are currently used in the pelvic region, to restore physiological anatomy after organ prolapse into the vaginal wall, that represent a recurrent dysfunction. For this purpose, synthetic meshes are surgically positioned in contact with the anterior and/or posterior vaginal wall, to inferiorly support prolapsed organs. Nonetheless, while mesh implantation restores physiological anatomy, it is often associated with different complications in the vaginal region. These potentially dangerous effects induce the surgical community to reconsider the safety and efficacy of mesh transvaginal placement. For this purpose, the evaluation of state-of-the-art research may provide the basis for a comprehensive analysis of mesh compatibility and functionality. The aim of this work is to review synthetic surgical meshes for pelvic organs prolapse repair, taking into account the mechanics of mesh material and structure, and to relate them with pelvic and vaginal tissue biomechanics. Synthetic meshes are currently available in different chemical composition, fiber and textile conformations. Material and structural properties are key factors in determining mesh biochemical and mechanical compatibility in vivo. The most significant results on vaginal tissue and surgical meshes mechanical characterization are here reported and discussed. Moreover, computational models of the pelvic region, which could support the surgeon in the evaluation of mesh performances in physiological conditions, are recalled. PMID:26615384

    The main sequelae of endometriosis are represented by infertility and chronic pelvic pain. Chronic pelvic pain causes disability and distress with a very high economic impact. In the last decades, an impressive amount of pharmacological agents have been tested for the treatment of endometriosis-associated pelvic pain. However, only a few of these have been introduced into clinical practice. Following the results of the controlled studies available, to date, the first-line treatment for endometriosis associated pain is still represented by oral contraceptives used continuously. Progestins represent an acceptable alternative. In women with rectovaginal lesions or colorectal endometriosis, norethisterone acetate at low dosage should be preferred. GnRH analogues may be used as second-line treatment, but significant side effects should be taken into account. Nonsteroidal anti-inflammatory drugs are widely used, but there is inconclusive evidence for their efficacy in relieving endometriosis-associated pelvic pain. Other agents such as GnRH antagonist, aromatase inhibitors, immunomodulators, selective progesterone receptor modulators, and histone deacetylase inhibitors seem to be very promising, but there is not enough evidence to support their introduction into routine clinical practice. Some other agents, such as peroxisome proliferator activated receptors-γ ligands, antiangiogenic agents, and melatonin have been proven to be efficacious in animal studies, but they have not yet been tested in clinical studies.

  13. Neuromodulation in Male Chronic Pelvic Pain Syndrome: Rationale and Practice

    2013-01-01

    This review explores the treatment of male chronic pelvic pain syndrome (CPPS) (i.e., chronic prostatitis) through the use of neuromodulation, which is the electrical stimulation of the nervous system. Neuromodulation has been used for the treatment of chronic pain for decades, and this review will examine the theory and use of neuromodulation and the various techniques available for the treatment of CPPS. Because of limited published research, much of the data presented will not be explicitly for male CPPS, but will be extrapolated from other chronic pelvic pain studies where neuromodulation has been used. Although several types of neuromodulation techniques are currently available for chronic pelvic pain conditions, none are considered standard therapies for treating CPPS. Despite the limited evidence, neuromodulation appears to provide benefits for some patients with CPPS. The improvement of urinary symptoms is more clearly defined than improvements in pain, but at least a subset of patients in most of the published studies and case series derive some benefit in the short term, and limited evidence suggests that long-term improvement of symptoms is possible. The debate about the pathophysiology of pelvic pain syndromes continues and the mechanism of action of neuromodulation on urinary and pain symptoms has yet to be defined. The fuller understanding of both will inform the evidence basis of using neuromodulation for male CPPS. PMID:23619478

    Fishes have adapted a number of different behaviors to move out of the water, but none have been described as being able to walk on land with a tetrapod-like gait. Here we show that the blind cavefish Cryptotora thamicola walks and climbs waterfalls with a salamander-like diagonal-couplets lateral sequence gait and has evolved a robust pelvic girdle that shares morphological features associated with terrestrial vertebrates. In all other fishes, the pelvic bones are suspended in a muscular sling or loosely attached to the pectoral girdle anteriorly. In contrast, the pelvic girdle of Cryptotora is a large, broad puboischiadic plate that is joined to the iliac process of a hypertrophied sacral rib; fusion of these bones in tetrapods creates an acetabulum. The vertebral column in the sacral area has large anterior and posterior zygapophyses, transverse processes, and broad neural spines, all of which are associated with terrestrial organisms. The diagonal-couplet lateral sequence gait was accomplished by rotation of the pectoral and pelvic girdles creating a standing wave of the axial body. These findings are significant because they represent the first example of behavioural and morphological adaptation in an extant fish that converges on the tetrapodal walking behaviour and morphology.

    Chronic pelvic pain (CPP) is a frequent and difficult problem because despite the quality and diversity of diagnostic procedures no relevant etiology will be found in 30 to 40% of all cases. Psychologic and psychotherapeutic counselling is than usually proposed and usually not well accepted. A different approach can now be proposed according to a new semeiologic overall. In many cases the pain dominant is not visceral but parietal. The pelvic envelope is actually more painfull than the pelvic content. In these cases one can evoke the diagnosis of pelvic fibromyalgia and this is quite similar to classic fibromyalgia. This pelvifibromyalgia can be quantified with an algometric index. This form of pain actually is the somatisation of a past and difficult issue which will be very slowly and progressively revealed in the realm of a multidisciplinary and simultaneous physical and psychological approach. In the majority of cases these women have occurred physical, moral or sexual trauma inflicted by family members or a third party. Taking in account the physical dimension of body pain at the same time as psychotherapy will considerably enhance the efficiency of treatment. In our experience 70% of all women will be cured using this new approach. PMID:11300048

  1. Acute kidney injury.

    Acute kidney injury (AKI) - an abrupt deterioration in renal function - causes a rise in serum creatinine (SCr) or fall in urine output. It is common, occurring in up to 20% of hospital admissions. Importantly, even small rises in SCr are associated with increased risk of death and longer hospital stays. A 2009 National Confidential Enquiry into Patient Outcome and Death report found that a proportion of AKI in secondary care was avoidable. In addition, management of established AKI was 'good' less than half the time. In practice, AKI represents a heterogeneous group of conditions, encompassing impairments in both kidney structure and function. Delivering disease-specific treatment early in the course of AKI may improve outcomes. The provision of best-practice care for all will rely on a better understanding of risk, and frameworks of care that can be applied across a diverse patient group. PMID:26621953

    [Purpose] The aim of this study was to evaluate whether the effect of pelvic floor exercises on pelvic floor muscle strength could be detected via ultrasonography in patients with urinary incontinence. [Subjects and Methods] Of 282 incontinent patients, 116 participated in the study and were randomly divided into a pelvic floor muscle training (n=65) group or control group (n=51). The pelvic floor muscle training group was given pelvic floor exercise training for 12 weeks. Both groups were evaluated at the beginning of the study and after 12 weeks. Abdominal ultrasonography measurements in transverse and longitudinal planes, the PERFECT scheme, perineometric evaluation, the stop test, the stress test, and the pad test were used to assess pelvic floor muscle strength in all cases. [Results] After training, the PERFECT, perineometry and transabdominal ultrasonography measurements were found to be significantly improved, and the stop test and pad test results were significantly decreased in the pelvic floor muscle training group, whereas no difference was observed in the control group. There was a positive correlation between the PERFECT force measurement scale and ultrasonography force measurement scale before and after the intervention in the control and pelvic floor muscle training groups (r=0.632 and r=0.642, respectively). [Conclusion] Ultrasonography can be used as a noninvasive method to identify the change in pelvic floor muscle strength with exercise training. PMID:27065519

    [Purpose] The purpose of this study was to compare changes in the mobility of the pelvic floor muscle during the abdominal drawing-in maneuver, maximal expiration, and pelvic floor muscle maximal contraction. [Subjects] Thirty healthy adults participated in this study (15 men and 15 women). [Methods] All participants performed a bridge exercise and abdominal curl-up during the abdominal drawing-in maneuver, maximal expiration, and pelvic floor muscle maximal contraction. Pelvic floor mobility was evaluated as the distance from the bladder base using ultrasound. [Results] According to exercise method, bridge exercise and abdominal curl-ups led to significantly different pelvic floor mobility. The pelvic floor muscle was elevated during the abdominal drawing-in maneuver and descended during maximal expiration. Finally, pelvic floor muscle mobility was greater during abdominal curl-up than during the bridge exercise. [Conclusion] According to these results, the abdominal drawing-in maneuver induced pelvic floor muscle contraction, and pelvic floor muscle contraction was greater during the abdominal curl-up than during the bridge exercise.

  8. Claudins and the Kidney

    PubMed Central

    2015-01-01

    Claudins are tight-junction membrane proteins that function as both pores and barriers in the paracellular pathway in epithelial cells. In the kidney, claudins determine the permeability and selectivity of different nephron segments along the renal tubule. In the proximal tubule, claudins have a role in the bulk reabsorption of salt and water. In the thick ascending limb, claudins are important for the reabsorption of calcium and magnesium and are tightly regulated by the calcium-sensing receptor. In the distal nephron, claudins need to form cation barriers and chloride pores to facilitate electrogenic sodium reabsorption and potassium and acid secretion. Aldosterone and the with-no-lysine (WNK) proteins likely regulate claudins to fine-tune distal nephron salt transport. Genetic mutations in claudin-16 and -19 cause familial hypomagnesemic hypercalciuria with nephrocalcinosis, whereas polymorphisms in claudin-14 are associated with kidney stone risk. It is likely that additional roles for claudins in the pathogenesis of other types of kidney diseases have yet to be uncovered. PMID:24948743

    Abstract: Acute kidney injury is a frequent and serious complication in hospitalized patients. Mortality rates have not substantially been decreased during the last 20 years. In most patients AKI results from transient renal hypoperfusion or ischemia. The consequences include tubular cell dysfunction/damage, inflammation of the organ, and post-ischemic microvasculopathy. The two latter events perpetuate kidney damage in AKI. Clinical manifestations result from diminished excretion of water, electrolytes, and endogenous / exogenous waste products. Patients are endangered by cardiovascular complications such as hypertension, heart failure, and arrhythmia. In addition, the whole organism may be affected by systemic toxification (uremia). The diagnostic approach in AKI involves several steps with renal biopsy inevitable in some patients. The current therapy focuses on preventing further kidney damage and on treatment of complications. Different pharmacological strategies have failed to significantly improve prognosis in AKI. If dialysis treatment becomes mandatory, intermittent and continuous renal replacement therapies are equally effective. Thus, new therapies are urgently needed in order to reduce short- and long-term outcome in AKI. In this respect, stem cell-based regimens may offer promising perspectives. PMID:25618438

  10. Pelvic skeleton reduction and Pitx1 expression in threespine stickleback populations.

    The pelvic skeleton of threespine stickleback fish contributes to defence against predatory vertebrates, but rare populations exhibit vestigial pelvic phenotypes. Low ionic strength water and absence of predatory fishes are associated with reduction of the pelvic skeleton, and lack of Pitx1 expression in the pelvic region is evidently the genetic basis for pelvic reduction in several populations. Pelvic vestiges in most populations are larger on the left (left-biased), apparently because Pitx2 is expressed only on that side. We used whole-mount in situ hybridization to study Pitx1 expression in 19 populations of Gasterosteus aculeatus from lakes around Cook Inlet, Alaska, USA. As expected, specimens from six populations with full pelvic structures usually expressed Pitx1 in the limb bud; those from eight populations with left-biased pelvic reduction usually did not express it. Specimens from one of three populations with right-biased or unbiased pelvic reduction sometimes expressed Pitx1. One of two populations in which the pelvic spines (but not the girdle) are usually absent often expressed Pitx1. In terms of Jacob's 1977 'tinkering' metaphor, Pitx1 was the spare part with which natural selection usually tinkered for stickleback pelvic reduction, but it also tinkered with other genes that have smaller effects.

    Given current evidence supporting a genetic predisposition for pelvic organ prolapse, we conducted a systematic review of published literature on the genetic epidemiology of pelvic organ prolapse. Inclusion criteria were linkage studies, candidate gene association and genome-wide association studies in adult women published in English and indexed in PubMed through Dec. 2012, with no limit on date of publication. Methodology adhered to the PRISMA guidelines. Data were systematically extracted by 2 reviewers and graded by the Venice criteria for studies of genetic associations. A metaanalysis was performed on all single nucleotide polymorphisms evaluated by 2 or more studies with similar methodology. The metaanalysis suggests that collagen type 3 alpha 1 (COL3A1) rs1800255 genotype AA is associated with pelvic organ prolapse (odds ratio, 4.79; 95% confidence interval, 1.91-11.98; P = .001) compared with the reference genotype GG in populations of Asian and Dutch women. There was little evidence of heterogeneity for rs1800255 (P value for heterogeneity = .94; proportion of variance because of heterogeneity, I(2) = 0.00%). There was insufficient evidence to determine whether other single nucleotide polymorphisms evaluated by 2 or more papers were associated with pelvic organ prolapse. An association with pelvic organ prolapse was seen in individual studies for estrogen receptor alpha (ER-?) rs2228480 GA, COL3A1 exon 31, chromosome 9q21 (heterogeneity logarithm of the odds score 3.41) as well as 6 single nucleotide polymorphisms identified by a genome-wide association study. Overall, individual studies were of small sample size and often of poor quality. Future studies would benefit from more rigorous study design as outlined in the Venice recommendations. PMID:24721264

    Background. Decubitus ulcers can become complicated by pelvic osteomyelitis. Little is known about the epidemiology of pressure ulcer-related pelvic osteomyelitis. Methods. We performed a retrospective cohort study of adult patients with pressure ulcer and pelvic osteomyelitis admitted to an academic center from 2006 to 2011. Data on clinical presentation, diagnostic evaluation, and treatment during the index admission were collected. Outcome measures included length of hospital stay and number of readmissions in the subsequent year. Results. Two hundred twenty patients were included: 163 (74%) were para/quadriplegic and 148 (67%) were male (148; 67%). Mean age was 50 (±18) years. Pelvic osteomyelitis was the primary admission diagnosis for 117 (53%). Fifty-six (26%) patients had concurrent febrile urinary tract infection. Wound cultures collected for 113 patients (51%) were notable for methicillin-resistant Staphylococcus aureus (37; 33%), Streptococci (19; 17%), and Pseudomonas spp (20; 18%). Plain films were obtained in 89 (40%) patients, computed tomography scans were obtained for 81 (37%) patients, and magnetic resonance images were obtained for 40 (18%) patients. Most patients received osteomyelitis-directed antibiotics (153; 70%), 134 of 153 (88%) of which were scheduled to receive ≥6 weeks of treatment. Fifty-five (25%) patients underwent surgery during the index admission; 48 (22%) patients received a combined medical-surgical approach. One third of patients had ≥2 readmissions during the subsequent year. Patients treated with a combined approach were less likely to be readmitted than those who received antibiotics alone (0 [range, 0–4] vs 1 [0–7] readmissions; P = .04). Conclusions. This is one of the largest cohort studies of pressure ulcer-related pelvic osteomyelitis to date. Significant variations existed in diagnostic approach. Most patients received antibiotics; those treated with a combined medical-surgical approach had fewer hospital readmissions. PMID:26322317

    The purpose of this study was to develop three-dimensional finite element models of the whole pelvic support systems of subjects with and without pelvic organ prolapse (POP) that can be used to simulate anterior and posterior wall prolapses. Magnetic resonance imaging was performed in one healthy female volunteer (55 years old, para 2) and one patient (56 years old, para 1) with anterior vaginal wall prolapse. Contours of the pelvic structures were traced by a trained gynecologist. Smoothing of the models was conducted and attachments among structures were established. Finite element models of the pelvic support system with anatomic details were established for both the healthy subject and the POP patient. The models include the uterus, vagina with cavity, cardinal and uterosacral ligaments, levator ani muscle, rectum, bladder, perineal body, pelvis, obturator internus, and coccygeal muscle. Major improvements were provided in the modeling of the supporting ligaments and the vagina with high anatomic precision. These anatomically accurate models can be expected to allow study of the mechanism of POP in more realistic physiological conditions. The resulting knowledge may provide theoretical help for clinical prevention and treatment of POP. PMID:25710033

    The ducts associated with sperm transport from the testicular lobules to the Wolffian ducts in Ambystoma maculatum were examined with transmission electron microscopy. Based on the ultrastructure and historical precedence, new terminology for this network of ducts is proposed that better represents primary hypotheses of homology. Furthermore, the terminology proposed better characterizes the distinct regions of the sperm transport ducts in salamanders based on anatomy and should, therefore, lead to more accurate comparisons in the future. While developing the above ontology, we also tested the hypothesis that nephrons from the genital kidney are modified from those of the pelvic kidney due to the fact that the former nephrons function in sperm transport. Our ultrastructural analysis of the genital kidney supports this hypothesis, as the basal plasma membrane of distinct functional regions of the nephron (proximal convoluted tubule, distal convoluted tubule, and collecting tubule) appear less folded (indicating decreased surface area and reduced reabsorption efficiency) and the proximal convoluted tubule possesses ciliated epithelial cells along its entire length. Furthermore, visible luminal filtrate is absent from the nephrons of the genital kidney throughout their entire length. Thus, it appears that the nephrons of the genital kidney have reduced reabsorptive capacity and ciliated cells of the proximal convoluted tubule may increase the movement of immature sperm through the sperm transport ducts or aid in the mixing of seminal fluids within the ducts.

    No data are available on the incidence of pelvic pain and organic dysfunction (PPOD) in patients suffering from low back pain. PPOD is not an uncommon finding in the low back pain patient. Women appear to be more frequently involved than men. The results of recent electrophysiologic investigations indicate that many patients with urological, bowel or anorectal dysfunction demonstrate evidence of denervation neuropathy in muscles innervated by the branches of the pudendal nerve. Six patients with low back pain meeting predetermined criteria, indicating the presence of PPOD as a result of suspected lower sacral nerve root compression (LSNRC) secondary to a mechanical disorder of the low back were treated with chiropractic distractive decompressive manipulation of the lumbar spine. Symptoms of PPOD, and indicators of LSNRC were assessed prior to the onset, and following the termination of treatment. It appears that selected indicators of LSNRC represent the most sensitive clinical signs of identifying the presence of PPOD which may respond to manipulative treatment, and may also provide the most sensitive measure of overall PPOD response. These findings, although preliminary suggest a possible etiology of PPOD in the low back pain patient with evidence of LSNRC. Further work in this area is encouraged. PMID:2527938

    Background Functional status plays an important role in the comprehensive characterization of older adults. Functional limitations are associated with an increased risk of adverse treatment outcomes, but there is limited data on the prevalence of functional limitations in older women with pelvic floor disorders. Objective The aim of the study was to describe the prevalence of functional limitations based on health status in older women with pelvic organ prolapse. Study Design This pooled, cross-sectional study utilized data from the linked Health and Retirement Study and Medicare files between 1992 and 2008. The analysis included 890 women ≥65 years with pelvic organ prolapse. We assessed self-reported functional status, categorized in strength, upper and lower body mobility, activities of daily living, and instrumental activities of daily living domains. Functional limitations were evaluated and stratified by respondents self-reported general health status. Descriptive statistics were used to compare categorical and continuous variables, and logistic regression was used to measure differences in the odds of functional limitation by increasing age. Results The prevalence of functional limitations was 76.2% in strength, 44.9% in upper and 65.8% in lower body mobility, 4.5% in activities of daily living and 13.6% in instrumental activities of daily living. Limitations were more prevalent in women with poor or fair health status than in women with good health status, including 91.5% vs 69.9% in strength, 72.9% vs 33.5% in upper and 88.0% vs 56.8% in lower body mobility, 11.6% vs 0.9% in activities of daily living, and 30.6% vs 6.7% in instrumental activities of daily living, all p<0.01. The odds of all functional limitations also increased significantly with advancing age. Conclusion Functional limitations, especially in strength and body mobility domains, are highly prevalent in older women with pelvic organ prolapse, particularly in those with poor or fair self-reported health status. Future research is necessary to evaluate if functional status affects clinical outcomes in pelvic reconstructive and gynecologic surgery and whether it should be routinely assessed in clinical decision-making when treating older women with pelvic organ prolapse.

    2015-02-01

    Presented is a retrospective outcome study of a 15-year single institutional experience with a contemporary cohort of patients with hypoplastic left heart syndrome and complex that underwent a "Giessen Hybrid" stage I as initial palliation. Hybrid approach consisting of surgical bilateral pulmonary artery banding and percutaneous duct stenting with or without atrial septum manipulation was developed from a rescue approach to a first-line procedure. Comprehensive Aristotle score defined pre-operative condition. Fifteen-year follow-up mortality is reported as occurring within the staged univentricular palliation or before and after biventricular repair. Hybrid stage I was performed in 154 patients; 107 should be treated by single ventricle palliation, 33 by biventricular repair (BVR), 7 received heart transplantation, and 7 were treated by comfort care, respectively. Overall 34 children died. The Aristotle score (mean value 18.2 ± 3) classified for univentricular circulations in newborns did not have statistical impact on the outcome. Two patients died during stage I (1.2%), and the interstage I mortality was 6.7%, and stage II mortality 9%, respectively. Stage III was up to now performed in 57 patients without mortality. At 1 year, the overall unadjusted survival of HLHS and variants was 84% and following BVR 89%, respectively. The Fifteen-year survival rate for HLHS and variants was 77%, with no significant impact of birth weight of less than 2.5 kg. In conclusion, Hybrid stage I fulfilled the criteria of life-saving approach. In our institution, Hybrid procedure replaced Norwood-staged palliation with a considerable mid- and long-term survival rate. Considering interstage mortality close surveillance is mandatory.

    Indications, procedures, complications, pharmacokinetics and outcomes of renal transplantation are different in children and in adults. Subjects <18 yrs old, are often included in a unique list as in Italy, benefiting from donors <15 yrs old, and the waiting time is reduced to <12 months in 71% of cases. The risk of thrombosis limits the use of donors <2 yrs and trans-plantation in infants <1 yr. The age at kidney transplantation is <5 yrs in 20-30% of children. In Italy living-related trans-plantation (LRT) is performed in 7% of cases, while in the USA it is more common (57%) and is often pre-emptive before entering dialysis (24%). Current therapy tends to reduce steroid treatment doses and, optimizing induction therapy with IL-2R inhibitors, using tacrolimus or mycophenolate or sirolimus. Transplanted patient survival is better in children than in adults (94-98% at 5 yrs). Infections, cardiovascular diseases and neoplasia induce 34, 15 and 12% of deaths, respectively, at 10 yrs; morbidity for infections and lymphoproliferative disease is increasing. Acute rejections declined from 70% in 1987 to 31% in 2002 in cadaveric transplantation (CT) and renal survival at 3 yrs increased from 50% in 1985 to 82% for CT and up to 92% in LRT. In adolescents (11-17 yrs old) renal survival is lower than in infants and in adults <65 yrs old. Renal losses are due to chronic transplant nephropathy (32%), vascular thrombosis (13%) and the recurrence of the original nephropathy (focal glomerulosclerosis up to 50%, membrano-proliferative glomerulonephritis up to 30%, and primary hyperoxaluria up to 90% if combined kidney-liver transplantation is not performed). Growth improves after transplantation particularly in children <5 yrs, while it is not completely satisfactory in adolescents. Overall, results indicate that kidney transplantation in children has very much improved and will offer in the near future even more favorable outcomes. PMID:16267794

    CD74 (invariant MHC class II) regulates protein trafficking and is a receptor for macrophage migration inhibitory factor (MIF) and d-dopachrome tautomerase (d-DT/MIF-2). CD74 expression is increased in tubular cells and/or glomerular podocytes and parietal cells in human metabolic nephropathies, polycystic kidney disease, graft rejection and kidney cancer and in experimental diabetic nephropathy and glomerulonephritis. Stressors like abnormal metabolite (glucose, lyso-Gb3) levels and inflammatory cytokines increase kidney cell CD74. MIF activates CD74 to increase inflammatory cytokines in podocytes and tubular cells and proliferation in glomerular parietal epithelial cells and cyst cells. MIF overexpression promotes while MIF targeting protects from experimental glomerular injury and kidney cysts, and interference with MIF/CD74 signaling or CD74 deficiency protected from crescentic glomerulonephritis. However, CD74 may protect from interstitial kidney fibrosis. Furthermore, CD74 expression by stressed kidney cells raises questions about the kidney safety of cancer therapy strategies delivering lethal immunoconjugates to CD74-expressing cells. Thus, understanding CD74 biology in kidney cells is relevant for kidney therapeutics. PMID:26441987

    Renal failure impairs the endocrine system, especially in women, due to hyperprolactinemia, altering fertility, ovulatory cycles, libido and growth in adolescents. Renal transplantation is considered the best solution to the problems of renal failure and and of dialysis, as evidenced by comparing the rate of hyperprolactinemia (100% in chronic renal failure, 60% in patients on dialysis and 35% in post-transplantation). Kidney transplant is less efficient for restoring perfect function of the hypothalamic-pituitary-gonadal axis due in part to the immunosuppressant regimens prescribed. When these drugs are properly managed, transplantation will restore near normal sexual function. PMID:26591193

    Human immunodeficiency virus (HIV) and antiretroviral therapy can damage the kidney. Highly active antiretroviral therapy (HAART) generally improves the renal function as it reduces the viral replication, although the renal function may be reduced by certain antiretroviral drugs. HAART causes acute tubular necrosis, acute interstitial nephritis, calculi, Fanconi Syndrome, crystal nephropathy, elevated lipid levels as well as calcium and phosphorus alteration. The physician must estimate renal function before and during antiretroviral therapy, especially when HIV-infected patients have some risk factors for renal damage such as high-blood pressure or hepatitis B or C infections.

    Valid measurement of pelvic and hip angles during posterior load carriage gait task requires placement of pelvic markers which will not be occluded or physically displaced by the load. One solution is the use of pure lateral pelvic clusters to track the pelvis segment. However, the validity of this method has not been compared against pelvic marker systems recommended by the International Society of Biomechanics (ISB) during high impact tasks, such as running. The purpose of this study was to validate the lateral tracking pelvic clusters against the ISB pelvis during running. Six participants performed overground running at a self-selected running speed with shoes. Three dimensional motion capture and synchronised in-ground force plates were used to determine lower limb joint angles and gait events respectively. Two biomechanical models were used to derive pelvic segment and hip joint angles. The ISB pelvis used the anterior and posterior iliac spines as anatomical and tracking markers, whilst the other model used lateral pelvic clusters as tracking markers. The between participant averaged coefficient of multiple correlation suggested good to excellent agreement between the angle waveforms generated from the two marker protocols. In addition, both marker protocols had similar sensitivity in detecting three dimensional pelvic and hip joint angles during the stance phase. This study suggests that in the event posterior load carriage is involved in running gait, pelvic and hip kinematics can be measured by the use of lateral pelvic clusters. PMID:27207384

    This study investigated the incidences of urinary incontinence and pelvic organ prolapse as well as pelvic floor muscle strength after cesarean section and vaginal delivery. From June 2010 to July 2011, 149 puerpera in Shenzhen Hospital, Peking University, were divided into the cesarean section group (N = 66) and the vaginal delivery group (N = 83). Postpartum urinary incontinence analysis, pelvic examination, and pelvic muscle contraction analysis using the PHENIX neuromuscular therapy instrument were performed to compare urinary incontinence, pelvic organ prolapse, and pelvic floor muscle condition between the 2 groups. The incidences of urinary incontinence in the cesarean and vaginal delivery groups were 9.09% (6/66) and 16.87% (14/83), respectively (P > 0.05); the incidences of pelvic organ prolapse were 53.03% (35/66) and 86.75% (72/83), respectively (P < 0.05). There was no significant difference in pelvic muscle pressure or electrophysiological examination results between the 2 groups (P > 0.05). Hence, cesarean section has a protective effect on early postpartum pelvic organ prolapse, but the delivery modes do not differ significantly with respect to the incidence of postpartum urinary incontinence or pelvic muscle floor muscle strength.

    PubMed Central

    2011-01-01

    A large number of scientists from a wide range of medical and surgical disciplines have reported on the existence and characteristics of the clinical syndrome of pelvic girdle pain during or after pregnancy. This syndrome refers to a musculoskeletal type of persistent pain localised at the anterior and/or posterior aspect of the pelvic ring. The pain may radiate across the hip joint and the thigh bones. The symptoms may begin either during the first trimester of pregnancy, at labour or even during the postpartum period. The physiological processes characterising this clinical entity remain obscure. In this review, the definition and epidemiology, as well as a proposed diagnostic algorithm and treatment options, are presented. Ongoing research is desirable to establish clear management strategies that are based on the pathophysiologic mechanisms responsible for the escalation of the syndrome's symptoms to a fraction of the population of pregnant women.

    The control of the massive and often fatal hemorrhage from pelvic neoplasms is a major therapeutic problem. Transcatheter embolization of the internal iliac arteries was performed in 108 patients with uncontrollable hemorrhage due to pelvic neoplasms (urinary bladder in 50, uterus in 39, ovary in 16, and prostate in three). Complete control of the hemorrhage was achieved in 74 patients, partial control in 23, and no control in 11. Seventy patients experienced postembolization syndrome (nausea, vomiting, gluteal pain, and fever due to tissue necrosis), and three had transient acute tubular necrosis caused by the contrast medium. It is important for success that the embolization be bilateral and that the embolic agent used be a permanent one. PMID:2748811

    The conservative treatment of deep leg and pelvic vein thrombosis leads to permanent damage of recanalised veins, which in cases of long distance clots as well as involvement of the pelvic level, increase the risk of developing a postthrombotic syndrome. Such subsequent damage of the deep veins can only be avoided if occluded veins are rapidly recanalised and the function of the valves is successfully reestablished. Recanalisation may consist of surgical, fibrolytic and interventional methods and aims to minimize any subsequent damage; however no potential benefit of recanalisation versus standard treatment has yet been proven by means of methodologically adequate comparative studies. Thus, the indications for recanalisation must remain strict and be founded on a thorough risk-benefit assessment. PMID:25995092

Timely diagnosis of the disease is confusing due to its nonspecific clinical features. Case. A 28-year-old woman at 34 weeks of gestation with severe pain in her right buttock radiating down the backside of the right thigh was admitted to our hospital. White blood cell (WBC) count and C-reactive protein (CRP) were elevated. The pelvic magnetic resonance imaging (MRI) scan revealed right sacroiliitis. Conclusion. Infectious sacroiliitis should be considered as a differential diagnosis even in low-risk women who present with debilitating pelvic pain in pregnancy and medical treatment should not be delayed.

    Isolated torsion of hydrosalpinx is a rare cause of acute pelvic pain. Pre-operative diagnosis is very difficult because of non specific clinical presentation. Definitive diagnosis is always made at surgical exploration performed for suspected adnexal torsion and salpingectomy is performed in the majority of cases. A 34-year-old woman was admitted for acute pelvic pain with nausea and vomiting. Vaginal examination revealed a right adnexal tender mass and ultrasound revealed a well circumscribed right adnexal cystic mass. Surgical exploration has revealed torsion of a right hydrosalpinx and right salpingectomy was performed. Differential diagnosis between adnexal and tubal torsion is very difficult, however both should be managed by rapid surgical exploration which an allow precocious diagnosis and conservative treatment.

These conditions include malignancies, infections, and, rarely, congenital diseases. Case Report: We report a case of an inadvertent transmission of polycystic kidney disease from a 40-year-old trauma victim to both kidney recipients. There was no family history of renal disease in the donor. The renal allografts gradually increased in size with the development of cysts and functioned for 10 and 14 years. Conclusions: We report a case of inadvertent transmission of polycystic kidney disease from an unsuspecting deceased donor to both the recipients through renal allograft. Both the grafts lasted long enough to suggest that polycystic kidneys from deceased donors can be considered for transplantation. PMID:25716074

    Context: Obesity, both directly and indirectly, increases the risk for a variety of disease conditions including diabetes, hypertension, liver disease, and certain cancers, which in turn, decreases the overall lifespan in both men and women. Though the cardiovascular risks of obesity are widely acknowledged, less often identified is the relationship between obesity and renal function. Evidence Acquisitions: Directory of Open Access Journals (DOAJ), Google Scholar, PubMed, EBSCO and Web of Science has been searched. Results: The concept of the “Metabolic Syndrome“ helps us to understand this close link between obesity, diabetes, hypertension, and renal dysfunction. An elevated body mass index has shown to be one of the major determinants of glomerular hyperfiltration that lead to the development of chronic kidney disease. Interestingly, weight loss can lead to attenuation of hyperfiltration in severely obese patients suggesting a possible therapeutic option to combat obesity-related hyperfiltration. Conclusions: Various treatment strategies had been suggested to decrease impact of obesity on kidneys. These are blood pressure controling, inhibition of the renin-angiotensinaldosterone axis, improving glycemic control, improving dyslipidemia, improving protein uriaand lifestyle modifications. Regardless of the numerous pharmacotherapies, the focus should be on the root cause: obesity. PMID:25093156

    2015-07-01

    Pruritus is a common and distressing symptom in patients with chronic kidney disease. The most recent epidemiologic data have suggested that approximately 40% of patients with end-stage renal disease experience moderate to severe pruritus and that uremic pruritus (UP) has a major clinical impact, being associated strongly with poor quality of life, impaired sleep, depression, and increased mortality. The pathogenesis of UP remains largely unclear, although several theories on etiologic or contributing factors have been proposed including increased systemic inflammation; abnormal serum parathyroid hormone, calcium, and phosphorus levels; an imbalance in opiate receptors; and a neuropathic process. UP can present somewhat variably, although it tends to affect large, discontinuous, but symmetric, areas of skin and to be most symptomatic at night. A variety of alternative systemic or dermatologic conditions should be considered, especially in patients with asymmetric pruritus or other atypical features. Treatment initially should focus on aggressive skin hydration, patient education on minimizing scratching, and optimization of the aspects of chronic kidney disease care that are most relevant to pruritus, including dialysis adequacy and serum parathyroid hormone, calcium, and phosphorus management. Data for therapy specifically for UP remain limited, although topical therapies, gabapentin, type B ultraviolet light phototherapy, acupuncture, and opioid-receptor modulators all may play a role.

    Acute kidney injury (AKI) is a global public health concern associated with high morbidity, mortality, and healthcare costs. Other than dialysis, no therapeutic interventions reliably improve survival, limit injury, or speed recovery. Despite recognized shortcomings of in vivo animal models, the underlying pathophysiology of AKI and its consequence, chronic kidney disease (CKD), is rich with biological targets. We review recent findings relating to the renal vasculature and cellular stress responses, primarily the intersection of the unfolded protein response, mitochondrial dysfunction, autophagy, and the innate immune response. Maladaptive repair mechanisms that persist following the acute phase promote inflammation and fibrosis in the chronic phase. Here macrophages, growth-arrested tubular epithelial cells, the endothelium, and surrounding pericytes are key players in the progression to chronic disease. Better understanding of these complex interacting pathophysiological mechanisms, their relative importance in humans, and the utility of biomarkers will lead to therapeutic strategies to prevent and treat AKI or impede progression to CKD or end-stage renal disease (ESRD).

    OBJECTIVE To review the current literature and summarize the effect of obesity on outcomes of surgical treatment of pelvic floor disorders (PFDs) as well as the effect of weight loss on PFD symptoms. DATA SOURCES Relevant sources were identified by a MEDLINE search from 1966 to 2007 (key words: obesity, pelvic floor disorders, urinary incontinence, fecal incontinence, pelvic organ prolapse). References of relevant studies were hand searched. METHODS OF STUDY SELECTION Relevant human observational studies, randomized trials, and review articles were included. 246 articles were identified; 20 were used in reporting and analyzing the data. Meta-analyses were performed for topics meeting the appropriate criteria. TABULATION, INTEGRATION AND RESULTS There is good evidence that surgery for stress urinary incontinence in obese women is as safe as in their non-obese counterparts, but cure rates may be lower in the obese patient. Meta-analysis revealed cure rates of 81% and 85% for the obese and non-obese groups, respectively [P < 0.001; OR: 0.576 (95% CI: 0.426 – 0.779)] Combined bladder perforation rates were 1.2% in the obese and 6.6% in the non-obese [P = 0.015; OR: 0.277 (95% CI: 0.098 – 0.782)]. There is little evidence on which to base clinical decisions regarding the treatment of fecal incontinence (FI) and pelvic organ prolapse (POP) in obese women, as few comparative studies were identified addressing the outcomes of prolapse surgery in obese patients compared to normal-weight controls. Weight loss studies indicate that both bariatric and non-surgical weight loss lead to significant improvements in PFD symptoms. CONCLUSION Surgery for UI in obese women is safe, but more trials are needed to evaluate its long-term effectiveness as well as treatments for both FI and POP. Weight loss, both surgical and non-surgical, should be considered in the treatment of PFDs in the obese woman. PMID:18669733

    Pelvic floor disorders affect up to 24% of adult women in the United States, and many patients with pelvic organ prolapse (POP) choose to undergo surgical repair to improve their quality of life. While a variety of surgical repair approaches and techniques are utilized, including mesh augmentation, there is limited comparative effectiveness and safety outcome data guiding best practice. In conjunction with device manufacturers, federal regulatory organizations, and professional societies, the American Urogynecologic Society developed the Pelvic Floor Disorders Registry (PFDR) designed to improve the quality of POP surgery by facilitating quality improvement and research on POP treatments. The PFDR will serve as a resource for surgeons interested in benchmarking and outcomes data and as a data repository for Food and Drug Administration-mandated POP surgical device studies. Provider-reported clinical data and patient-reported outcomes will be collected prospectively at baseline and for up to 3 years after treatment. All data elements including measures of success, adverse events, and surgeon characteristics were identified and defined within the context of the anticipated multifunctionality of the registry, and with collaboration from multiple stakeholders. The PFDR will provide a platform to collect high-quality, standardized patient-level data from a variety of nonsurgical (pessary) and surgical treatments of POP and other pelvic floor disorders. Data from this registry may be used to evaluate short- and longer-term treatment outcomes, patient-reported outcomes, and complications, as well as to identify factors associated with treatment success and failure with the overall goal of improving the quality of care for women with these conditions.

    Background and Objective: Chronic pelvic pain affects 15% of women. Our objective was to evaluate empiric laparoscopic inguinal exploration and mesh placement in this population. Methods: Retrospective cohort with follow-up questionnaire of women with lateralizing chronic pelvic pain (right or left), ipsilateral inguinal tenderness on pelvic examination, no clinical hernia on abdominal examination, and ipsilateral empiric laparoscopic inguinal exploration with mesh placement (2003–2009). Primary outcome was pain level at the last postoperative visit. Secondary outcomes were pain level and SF-36 scores from the follow-up questionnaire. Results: Forty-eight cases met the study criteria. Surgery was done empirically for all patients, with only 7 patients (15%) found to have an ipsilateral patent processus vaginalis (shallow peritoneal dimple or a deeper defect (occult hernia)). Of 43 cases informative for the primary outcome, there was pain improvement in 15 patients (35%); pain improvement then return of the pain in 18 patients (42%); and pain unchanged in 9 patients (21%) and worse in 1 patient (2%). Improvement in pain was associated with a positive Carnett's test in the ipsilateral abdominal lower quadrant (P = .024). Thirteen patients returned the questionnaire (27%), and the pain was now described as improved in 9 patients (69%), unchanged in 4 patients (31%), and worse in none. Three SF-36 subscales showed improvement (physical functioning, social functioning, and pain). Conclusion: In select women with chronic pelvic pain, empiric laparoscopic inguinal exploration and mesh placement results in moderate improvement in outcome. A positive Carnett's test in the ipsilateral abdominal lower quadrant is a predictor of better outcome. PMID:23743375

    Abstract Pelvic fractures can result in life-threatening hemorrhages or other associated injuries. Therefore, computed tomography (CT) scanning plays a key role in the management of pelvic fracture patients. However, CT scanning is utilized as an adjunct in secondary survey according to traditional Advanced Trauma Life Support (ATLS) guidelines, whereas pelvic x-ray is used as a primary tool to evaluate pelvic stability and the necessity of further CT scanning. In the current study, we attempted to evaluate the role of CT scanning in the era of advanced technology. The significance of pelvic stability was also analyzed. From January 2012 to December 2014, the trauma registry and medical records of pelvic fracture patients were retrospectively reviewed. A 64-slice multidetector CT scanner was used in our emergency department as a standard diagnostic tool for evaluating trauma patients. Pelvic x-ray was used as a primary tool for screening pelvic fractures, and pelvic stability was evaluated accordingly. CT scans were performed in patients with unstable pelvic fractures, suspected associated intra-abdominal injuries (IAIs), or other conditions based on the physicians’ clinical judgment. The clinical features of patients with stable and unstable pelvic fractures were compared. The patients with stable pelvic fractures were analyzed to determine the characteristics associated with retroperitoneal hemorrhage (RH) or IAIs. Patients with stable pelvic fractures were also compared based on whether they underwent a CT scan. A total of 716 patients were enrolled in this study. There were 533 (74.4%) patients with stable pelvic fractures. Of these patients, there were 66 (12.4%) and 50 (9.4%) patients with associated RH and IAI, respectively. There were no significant differences between the patients with associated RH based on their primary evaluation (vital signs, volume of blood transfusion, and hemoglobin level). Similarly, the demographics and the primary evaluation results (symptoms, coma scale, and white blood cell counts) of the patients with associated IAIs were also not significantly different from the patients without associated IAIs. Furthermore, the time to definitive hemostasis (surgery or angioembolization) was not significantly different between the unstable patients who underwent a CT scan or those who did not. In the management of pelvic fracture patients, the role of pelvic stability is not significant in the evaluation of associated RH or IAI. Routine CT scanning is suggested for pelvic fracture patients because of the rapid scanning time and sufficient information produced. PMID:27100433

    Uterine prolapse consists of a falling or sliding of the uterus from its normal position in the pelvic cavity inside the vagina and is one of the most frequent alterations secondary to pelvic floor dysfunction in gynecology consultations. Although patients are reluctant to talk about this sensitive issue, they complain of feeling a lump in their genitals, urinary incontinence, and problems in their sexual relations. In fact, uterine prolapse is not a disease but an alteration of the elements suspending and containing the uterus, which are almost always injured by pregnancy and childbirth. Other causes in addition to trauma of the endopelvic fascia (mainly cardinal and uterosacral ligaments) are injuries or relaxations of the pelvic floor (the muscles lifting the anus and the fascia that covers the bladder, vagina and rectum). Causes of uterine prolapse without obstetric antecedents are usually those that involve an increase in abdominal pressure and respiratory diseases causing severe coughing. The incidence of uterine prolapse is highest in multiparous women, with prolonged deliveries, a long second stage involving marked straining, in forceps deliveries and in women with perineal tears. Nursing care is essential, both in the prevention and the detection of prolapse, so that women can express their needs without fear and are aware of the need for appropriate treatment in the incipient stages of prolapse.

    CT was used in 50 adult pelvic fractures to determine the size and the position of relevant muscles with regard to bony elements in order to calculate muscle forces acting upon certain pelvic portions. Muscle length was measured to calculate muscle volume and physiological muscle cross-section. Among others, the size and direction of muscle forces were calculated for iliac, pubic and ischiadic fractures. The strongest muscle acting in iliac fractures is m. gluteus medius. The strongest upward pulling of iliac bone fragments is exerted by the erector muscles, while the major anterior, medial and downward pulling is performed by the iliopsoas muscle. In pubic bone fractures, eight muscles push bone fragments downward, the strongest among them being m. adductor magnus. Two muscles pull them upwards: m. rectus abdominis and m. obliquus externus. Nine muscles are responsible for downward displacement of bone fragments in ischiadic fractures, but the strongest is m. semitendinosus. Calculation of moments of muscle forces acting upon bone fragments using CT of pelvic fractures gives additional data for planning of optimal operative treatment that can guarantee stable fixation in individual patients.

    2006-01-01

    Background: Chronic pelvic pain in women due to hernias may be misdiagnosed by practicing clinicians. These fascial defects, their symptoms, physical findings, and proper treatment must be known in order to help women experiencing this form of chronic pelvic pain. Methods: All procedures were performed by the primary author using standard laparoscopic tension-free mesh techniques. Results: The study included 264 patients referred to a chronic pelvic pain clinic, who underwent 386 laparoscopic surgical repairs of hernial defects. Ninety percent of the patients underwent concomitant procedures appropriate for their multiple pain generators. Length of follow-up is 1.53 years (range, 2 months to 5.5 years). Evaluation of patients’ pain component from the repaired hernia was recorded. There have been no recurrences. One persistent ilioinguinal neuropathy from an inguinal hernia repair (.4%) has occurred. All other patients received relief of their hernia pain (99.6%). Four complications from concomitant surgeries (1.5%) are reported. Conclusions: Laparoscopic treatment of hernia pain in women is effective in relieving chronic pain and has a low recurrence and complication rate in the hands of experienced laparoscopists.

    The pelvic floor gives support to the organs in the abdominal cavity. Using the dataset made public in (Janda et al. J. Biomech. (2003) 36(6), pp. 749-757), we have reconstructed the geometry of one of the most important parts of the pelvic floor, the levator ani, using NURB surfaces. Once the surface is triangulated, the corresponding mesh is used in a finite element analysis with shell elements. Based on the 3D behavior of the muscle we have constructed a shell that takes into account the direction of the muscle fibers and the incompressibility of the tissue. The constitutive model for the isotropic strain energy and the passive strain energy stored in the fibers is adapted from Humphrey's model for cardiac muscles. To this the active behavior of the skeletal muscle is added. We present preliminary results of a simulation of the levator ani muscle under pressure and with active contraction. This research aims at helping simulate the damages to the pelvic floor that can occur after childbirth. PMID:16298856

    Pelvic inflammatory disease (PID) can be responsible for infertility and chronic pelvic pain. Treatment of acute PID is very important as it can reduce the risk of sequelae. However, follow-up, partner treatment and counselling are also useful to reduce the reinfection rate. Few weeks after PID, clinical evaluation as well as transvaginal and transabdominal sonography must be performed. The interest of systematic bacteriological tests is not proved. Hysterosalpingography and second-look laparoscopy should be considered only for women with infertility and severe infection. Use of condom is advisable in this population in order to prevent sexually transmitted diseases (STD) including HIV and to decrease rate of recurrence, associated to contraceptive pill, which is also a good option. In selected cases, intrauterine devices can be used in patients with history of PID if the infection is resolved and no significant risk factors for STD exist. Infertility and chronic pelvic pain are the most common sequelae in the population of young women with severe and recurrent infection. The risk of ectopic pregnancy is higher for these women and must be kept in mind. Counselling and risk-reduction interventions decreased significatively the rate of recurrence and sequelae in PID.

    Pelvic organ prolapse is an extremely common condition, with approximately 12% of women requiring surgical correction over their lifetime. This manuscript reviews the most recent literature regarding the comparative efficacy of various surgical repair techniques in the treatment of advanced stage pelvic organ prolapse. Uterosacral ligament suspension has similar anatomic and subjective outcomes when compared to sacrospinous ligament fixation at 12 months and is considered to be equally effective. The use of transvaginal mesh has been shown to be superior to native tissue vaginal repairs with respect to anatomic outcomes but at the cost of a higher complication rate. Minimally invasive sacrocolpopexy appears to be equivalent to abdominal sacrocolpopexy (ASC). Robot-assisted sacrocolpopexy (RSC) and laparoscopic sacrocolpopexy (LSC) appear as effective as abdominal sacrocolpopexy, however, prospective studies of comparing long-term outcomes of ASC, LSC, and RSC in relation to health care costs is paramount in the near future. Surgical correction of advanced pelvic organ prolapse can be accomplished via a variety of proven techniques. Selection of the correct surgical approach is a complex decision process and involves a multitude of factors. When deciding on the most suitable surgical intervention, the chosen route must be individualized for each patient taking into account the specific risks and benefits of each procedure.

    Introduction Functional constipation (FC) is one of the most common gastrointestinal problems among children. This study was designed to investigate the effectiveness of pelvic floor muscle exercise on treatment of FC. Materials and Methods In this study which was conducted in Children’s Medical Center, children with a diagnosis of FC (aged 4-18 y) who did not respond to medical treatment, performed sessions of pelvic floor muscle exercise at home twice a day for 8 wk. Frequency of defecation, overall improvement of constipation, stool withholding, painful defecation and stool consistency were measured at the final week of the intervention compared to baseline. Results Forty children (16 males, 24 females mean age 5.6±1.03 y) completed the 8-wk exercise program. Subjective overall improvement of the symptoms was present in 36 patients (90%). The changes in stool frequency, stool diameter and consistency were statistically significant. However, there were no statistically significant differences in the stool withholding, fecal impaction, fecal incontinence and painful defecation. Conclusion Pelvic floor muscle exercise is an effective non-pharmacologic treatment for Paediatric FC. PMID:26284199

    In total hip replacement (THR) one technical factor influencing the risk of dislocation is cup orientation. Computer-assisted surgery systems allow for cup navigation in anatomy-based reference frames. The pelvic coordinate system most used for cup navigation in THR is based on the mid-sagittal plane (MSP) and the anterior pelvic plane (APP). From a geometrical point of view, the MSP can be considered as a mirror plane, whereas the APP can be considered as a tangent plane comprising the anterior superior iliac spines (ASIS) and the pubic tubercles. In most systems relying on the pelvic coordinate system, the most anterior points of the ASIS and the pubic tubercles are selected manually. As manual selection of landmark points is a tedious, time-consuming and error-prone task, a surface-based approach for combined MSP and APP computation is presented in this paper: Homologous points defining the MSP and the landmark points defining the APP are selected automatically from surface patches. It is investigated how MSP computation can benefit from APP computation and vice versa, and clinical perspectives of combined MSP and APP computation are discussed. Experimental results on computed tomography data show that the surface-based approach can improve accuracy.

    Tubulocystic carcinoma (TCC) of the kidney is a unique, rare, and recently recognized neoplasm. Although originally considered a low-grade collecting duct carcinoma, TCC is now considered to be a distinct entity. TCC should be considered in the differential diagnosis of cystic renal neoplasms. We report a case of TCC arising in the left kidney. PMID:26130898

    Rho family GTPases act as molecular switches regulating actin cytoskeleton dynamics. Attenuation of their signaling capacity is provided by GTPase-activating proteins (GAPs), including p190A, that promote the intrinsic GTPase activity of Rho proteins. In the current study we have performed a small-scale ENU mutagenesis screen and identified a novel loss of function allele of the p190A gene Arhgap35, which introduces a Leu1396 to Gln substitution in the GAP domain. This results in decreased GAP activity for the prototypical Rho-family members, RhoA and Rac1, likely due to disrupted ordering of the Rho binding surface. Consequently, Arhgap35-deficient animals exhibit hypoplastic and glomerulocystic kidneys. Investigation into the cystic phenotype shows that p190A is required for appropriate primary cilium formation in renal nephrons. P190A specifically localizes to the base of the cilia to permit axoneme elongation, which requires a functional GAP domain. Pharmacological manipulations further reveal that inhibition of either Rho kinase (ROCK) or F-actin polymerization is able to rescue the ciliogenesis defects observed upon loss of p190A activity. We propose a model in which p190A acts as a modulator of Rho GTPases in a localized area around the cilia to permit the dynamic actin rearrangement required for cilia elongation. Together, our results establish an unexpected link between Rho GTPase regulation, ciliogenesis and glomerulocystic kidney disease. PMID:26859289

    Open pelvic fractures are caused by high-energy trauma. Injuries to other organs are common and the mortality rate can be as high as 50%. Perineal injury is reported in 5% of open pelvic fractures. We report a case of a 31-year-old man that had an open pelvic injury with Denis zone III fracture of the sacrum, lumbosacral dislocation, symphysis dislocation, bilateral pubic rami fractures and an extensile perineal wound. He underwent an early diverting colostomy in order to prevent pelvic sepsis and subsequent stage reconstruction of the pelvic ring. At a 4-year follow-up a full recovery was present. The aim of this paper is to underline the importance of a safe, approach to manage open pelvic fractures. PMID:26738461

    Purpose To describe surgical outcomes using the new device in pediatric neuromuscular scoliosis. Methods All patients with neuromuscular disorders requiring surgery with pelvic fixation for the correction of scoliosis in the period 2002–2009 were operated by the new pelvic rod fixation device. Coronal and sagittal alignment before and after surgery until the latest follow-up were evaluated by standard X-rays. Intraoperative and postoperative complications were recorded. Results All 18 study patients (mean age at surgery 15 years, range 10–27) achieved solid fusion at a mean follow-up of 41 months. The coronal Cobb angle improved from 82° ± 31° (range 36–168) to 33° ± 25° at the last follow-up (range 9–95 months) (P < 0.0001). Pelvic obliquity improved from 19° ± 6° (range 10–30) to 5° ± 5° (range 0–14) (P < 0.0001). Early complications included pneumonia, urinary tract infection, disseminated intravascular coagulation (DIC), and hypovolemic shock. Three patients required debriding and received prolonged antimicrobial therapy for deep wound infection (none required implant removal). At the latest follow-up, no patient complained of lumbar pain or worsening of ambulatory status or level of activity. Conclusion Surgery employing the new pelvic rod fixation device allowed solid fusion and fixation with significant correction of multiplanar deformity, but the complication rate was high.

    Purpose: To inform radiation treatment planning for clinically staged, node-negative bladder cancer patients by identifying clinical factors associated with the presence and location of occult pathologic pelvic lymph nodes. Methods and Materials: The records of patients with clinically staged T1-T4N0 urothelial carcinoma of the bladder undergoing radical cystectomy and pelvic lymphadenectomy at a single institution were reviewed. Logistic regression was used to evaluate associations between preoperative clinical variables and occult pathologic pelvic or common iliac lymph nodes. Percentages of patient with involved lymph node regions entirely encompassed within whole bladder (perivesicular nodal region), small pelvic (perivesicular, obturator, internal iliac, and external iliac nodal regions), and extended pelvic clinical target volume (CTV) (small pelvic CTV plus common iliac regions) were calculated. Results: Among 315 eligible patients, 81 (26%) were found to have involved pelvic lymph nodes at the time of surgery, with 38 (12%) having involved common iliac lymph nodes. Risk of occult pathologically involved lymph nodes did not vary with clinical T stage. On multivariate analysis, the presence of lymphovascular invasion (LVI) on preoperative biopsy was significantly associated with occult pelvic nodal involvement (odds ratio 3.740, 95% confidence interval 1.865-7.499, P<.001) and marginally associated with occult common iliac nodal involvement (odds ratio 2.307, 95% confidence interval 0.978-5.441, P=.056). The percentages of patients with involved lymph node regions entirely encompassed by whole bladder, small pelvic, and extended pelvic CTVs varied with clinical risk factors, ranging from 85.4%, 95.1%, and 100% in non-muscle-invasive patients to 44.7%, 71.1%, and 94.8% in patients with muscle-invasive disease and biopsy LVI. Conclusions: Occult pelvic lymph node rates are substantial for all clinical subgroups, especially patients with LVI on biopsy. Extended coverage of pelvic lymph nodes up to the level of the common iliac nodes may be warranted in subsets of patients.

    Trauma is one of the leading causes of death before the age of 40 years and approximately 5% of patients with trauma who require hospital admission have pelvic fractures. This article updates the emergency department classification of pelvic fractures first described in 2000. This information is of practical value to emergency physicians in identifying the potential vascular, genitourinary, gastrointestinal, orthopedic, and neurologic complications and further assists them in the initial evaluation and treatment of patients with pelvic fractures.

    A 48-year-old man with a solitary fibrous tumor of the pelvic underwent resection, but recurrent tumor was found 4 years later. Recurrent solitary fibrous tumor of the pelvic with malignant progression is rare. Solitary fibrous tumor of the pelvic often has an indolent clinical course, so postoperative surveillance may necessitate long-term follow-up because of the potential adverse biological behavior of this tumor, which may lead to repeated recurrences and/or malignant transformation.

    The normally occurring loosening of the pelvic joints with separation of the symphysis during pregnancy may give rise to pain over the symphysis pubis or/and over the sacroiliac joints. In contrast, increased mobility between the pubic bones and pelvic pain without any direct connection with pregnancy is rare and its etiology is unclear. The following is a report of a patient who experienced symphysiolysis-like pelvic pain following the use of a levonorgestrel-releasing intrauterine system. PMID:21058450

  20. Role of kidney biomarkers of chronic kidney disease: An update

    Chronic kidney disease (CKD) is a progressive pathological condition marked by deteriorating renal function over time. Diagnostic of kidney disease depend on serum creatinine level and glomerular filtration rate which is detectable when kidney function become half. The detection of kidney damage in an early stage needs robust biomarkers. Biomarkers allow monitoring the disease progression at initial stages of disease. On the onset of impairment in cellular organization there is perturbation in signaling molecules which are either up-regulated or down-regulated and act as an indicator or biomarker of diseased stage. This review compiled the cell signaling of different kidney biomarkers associated with the onset of chronic kidney diseases. Delay in diagnosis of CKD will cause deterioration of nephron function which leads to End stage renal disease and at that point patients require dialysis or kidney transplant. Detailed information on the complex network in signaling pathway leading to a coordinated pattern of gene expression and regulation in CKD will undoubtedly provide important clues to develop novel prognostic and therapeutic strategies for CKD.
