  1. Spontaneous Posterior Uterine Rupture in Twin-Twin Transfusion Syndrome

    PubMed Central

    Smid, Marcela C.; Waltner-Toews, Rebecca; Goodnight, William

    2015-01-01

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

    We report a case of uterine artery rupture in a woman at 14 weeks' gestation who presented with abdominal pain, tachycardia, and hypotension and underwent a diagnostic laparoscopy. During this procedure, a spontaneous rupture of the left uterine artery was diagnosed and the surgery was converted into a laparotomy. The artery was bound to its origin and to its distal uterine portion. The patient exhibited excellent postoperative recovery and was discharged two days after the surgery. The pregnancy continued without other maternal or fetal complications, and the patient delivered a healthy newborn via cesarean section at 39 weeks of gestation. PMID:27891272

  3. A case of spontaneous hemoperitoneum by uterine vessel rupture in pregnancy

    A 27-year-old pregnant woman, para 1, was transferred to our hospital at 29+3 weeks of gestation complaining of abdominal pain. She was diagnosed with hemoperitoneum based on ultrasonography. An emergency laparotomy was performed, and the bleeding was confirmed to be caused by ruptured surface blood vessels on the uterine fundus. Hemostasis with compression was successfully performed to sustain the pregnancy, and the patient delivered a full-term baby. Spontaneous hemoperitoneum during pregnancy caused by rupture of uterine blood vessels is very rare. It requires rapid diagnosis and surgical treatment because it increases the morbidity of the fetus and mother. In most incidences of spontaneous hemoperitoneum during pregnancy, a cesarean delivery is performed along with a simultaneous emergency laparotomy. However, in this case, the pregnancy was maintained to full term after surgical hemostasis, which prevented neonatal complications due to premature birth. PMID:27896257

  4. [Acute abdomen secondary to spontaneous uterine rupture associated with pyometra].

    PubMed

    2006-01-01

    A 71-year-old female with rheumatoid arthritis and chronic use of corticosteroids presented to the emergency room with 2 weeks of urinary symptoms, abdominal pain and a mass located in hypo-mesogastrium and both flanks. An X-ray film of the abdomen showed that bowels were displaced by the mass. Laboratory studies showed thrombocytosis (549,000/mm(3)) and leukocytosis (41,800/mm(3)). Several hours after her arrival the patient developed acute abdomen and surgery was indicated. A urinary catheter drained 2100 ml of urine and the abdominal mass was reduced in size but did not disappear. Surgery demonstrated that the urinary bladder covered the fundus and the anterior face of the uterus, where extensive necrosis and a 3-cm perforation were found; 400 ml of foul-smelling pus was drained from the uterine cavity. Due to necrosis, a hysterectomy was performed. The histopathological report indicated necrosis, atrophic cervicitis and endometritis; pus culture developed Escherichia coli and Proteus vulgaris. Despite administration of broad-spectrum antibiotics, the patient developed severe sepsis and died 11 days postoperatively. During a literature review, only one similar case was found. Acute abdomen due to uterine perforation secondary to pyometra and associated with chronic use of corticosteroids is a rare complication.

    The description of rare case of the Cushings syndrome in pregnancy resulting in the spontaneous rupture of uterus. A case report. Department of Gynecology and Obstetrics, 1st Medical Faculty of Charles University and Hospital Na Bulovce. The authors report the case of a 33 year old woman, who was admitted to the clinic in 30th week of pregnancy for elevated blood pressure and hypokalemia. Arterial hypertension was corrected with the combination of Vasocardin and Dopegyt. In 36th week of pregnancy the patient was admitted to the hospital with premature rupture of membranes. In less than sixteen hours the patient spontaneously gave birth to a healthy girl. Subsequently the patient suffered from abdominal pain. CT scan showed haemoperitoneum and a right adrenal mass and the surgical revision was performed. During the surgery uterine rupture was identified and the patient uderwent abdominal hysterectomy. Based on the endocrinological examination the diagnosis of Cushings syndrome was made. Three months after the delivery she underwent laparoscopic right adrenalectomy. Histological examination revealed adrenocortical oncocytoma. Cushings syndrome is rare in pregnancy and misdiagnosis is common. Symptoms mimic pregnancy complications. The disease is often diagnosed with delay even after delivery. The sonography and magnetic resonance are dominant imaging methods. Laboratory diagnosis is difficult due to pregnancy related changes. In spite of rarity of Cushings syndrome in pregnancy we should think about it in terms of the differential diagnosis of hypertension, diabetes, dysbalance of mineralogram and typical cushingoid habitus.

    The only prostaglandin analogue licensed in Italy for induction of labour in spontaneous and therapeutic abortion is gemeprost. The authors report a case of spontaneous uterine rupture of a scarred uterus, for previous caesarean sections, in a woman at 20 weeks of gestation with a diagnosis of spontaneous abortion. She received a pessary of gemeprost every three hours. After the fifth pessary, she complained of severe pain. At the ultrasound examination, uterine cavity appeared empty and the dead fetus was dislocated in the abdomen. Emergency laparotomy was performed and uterine tear was repaired. To induce labour for fetal demise or therapeutic abortion in second trimester in women with scarred uterus, the authors decided to lengthen the time between administrations of pessary from four to five hours depending on patient's symptoms. However the appropriate drug regimen has still to be found and more data are necessary.

    Spontaneous perforation is a very rare complication of pyometra. The clinical findings of perforated pyometra are similar to perforation of the gastrointestinal tract and other causes of acute abdomen. In most cases, a correct and definite diagnosis can be made only by laparotomy. We report two cases of diffuse peritonitis caused by spontaneous perforated pyometra. The first case is a 78-year-old woman with abdominal pain for which laparotomy was performed because of suspected incarcerated hernia. The second case is a 61-year-old woman with abdominal pain for which laparotomy was performed because of symptoms of peritonitis. At laparotomy of both cases, 1 liter of pus with the source of uterine was found in the abdominal cavity. The ruptured uterine is also detected. More investigations revealed no malignancy as the reason of the pyometra. PMID:24024054

  8. Spontaneous uterine rupture after abdominal myomectomy at the gestational age of 20 weeks in pregnancy: A case report

    PubMed Central

    2016-01-01

    Background: Uterine rupture in pregnancy is rare and often could be life threatening and catastrophic. Myomectomy is one of very common surgeries in gynecology, performed as the vaginal, abdominal and laparoscopic surgeries. Pregnancies occured after abdominal and laparoscopic myomectomy are high risk for uterine rapture. Case: Patient was a 28 Years old female, pregnant woman at the 20 wks of gestational age with abdominal pain and a history of abdominal myomectomy 6 yrs ago. Uterus was ruptured and fetus in amniotic sac was found in abdominal cavity. Conclusion: Early diagnosis of uterine rupture after myomectomy can save patients from death. PMID:27525334

    A 30-year-old gravida 2 para 1 was admitted to hospital 2 years after cesarean section at 20 weeks' gestation with acute onset of abdominal pain and hypovolaemic shock. Emergency laparotomy revealed a uterine rupture located in the anterior uterine wall caused by a placenta percreta and supracervical hysterectomy was performed. This site of invasion and finally rupture was in projection of the previous lower-segment cesarean section. This report illustrates the dramatic consequences of abnormal placentation after prior uterine surgery, which can already occur early during pregnancy and prior to the onset of labour. (c) 2008 S.

  10. Spontaneous uterine rupture at 14 weeks gestation during a pregnancy consecutive to an oocyte donation in a woman with Turner's syndrome.

    PubMed

    2015-04-01

    We describe a spontaneous uterine rupture at 14 weeks gestation in a Turner patient. A 39 year-old patient was admitted for abdominal pain and hypotension at 14 weeks of pregnancy. The pregnancy had been obtained by oocyte donation and in vitro fertilization (IVF) because of Turner's syndrome. The abdominal ultrasound scan showed a normal pregnancy and a conserved foetal cardiac activity. It also showed a large amount of free fluid in the perihepatic space. Haemoglobin was 11.2 g/dL. After hemodynamic degradation, urgent laparoscopy showed an unrepairable uterine rupture with partial exteriorisation of the pregnancy, and placenta percreta. Urgent conversion to laparotomy allowed haemostatic hysterectomy. Uterine rupture during pregnancy obtained by oocyte donation in Turner's syndrome may be life threatening. The possibility of such a complication should be considered before oocyte donation for IVF in Turner's patients. Early spontaneous uterine rupture (second trimester) is a challenging diagnostic that should be evoked in case of non-specific abdominal pain in the presence of risk factors.

  11. Arachnoid cyst spontaneous rupture.

    PubMed

    Marques, Inês Brás; Vieira Barbosa, José

    2014-01-01

    Arachnoid cysts are benign congenital cerebrospinal fluid collections, usually asymptomatic and diagnosed incidentally in children or adolescents. They may become symptomatic after enlargement or complications, frequently presenting with symptoms of intracranial hypertension. We report an unusual case of progressive refractory headache in an adult patient due to an arachnoid cyst spontaneous rupture. Although clinical improvement occurred with conservative treatment, the subdural hygroma progressively enlarged and surgical treatment was ultimately needed. Spontaneous rupture is a very rare complication of arachnoid cysts. Accumulation of cerebrospinal fluid accumulation in the subdural space causes sustained intracranial hypertension that may be life-threatening and frequently requires surgical treatment. Patients with arachnoid cysts must be informed on their small vulnerability to cyst rupture and be aware that a sudden and severe headache, especially if starting after minor trauma or a Valsalva manoeuvre, always requires medical evaluation.

    Complete uterine rupture is a rare peripartum complication associated with a catastrophic outcome. Because of its rarity, knowledge about its risk factors is not very accurate. Most previous studies were small and over a limited time interval. Moreover, international diagnostic coding was used in most studies. These codes are not able to differentiate between the catastrophic complete type and less catastrophic partial type. Complete uterine rupture is expected to increase as the rate of cesarean delivery increases. Thus, we need more accurate knowledge about the risk factors for this complication. The objective of the study was to estimate the incidence and risk factors for complete uterine rupture during childbirth in Norway. This population-based study included women that gave birth after starting labor in 1967-2008. Data were from the Medical Birth Registry of Norway and Patient Administration System, complemented with information from medical records. We included 1,317,967 women without previous cesarean delivery and 57,859 with previous cesarean delivery. The outcome was complete uterine rupture (tearing of all uterine wall layers, including serosa and membranes). Risk factors were parameters related to demographics, pregnancy, and labor. Odds ratios for complete uterine rupture were computed with crude logistic regressions for each risk factor. Separate multivariable logistic regressions were performed to calculate the adjusted odds ratios and 95% confidence intervals. Complete uterine rupture occurred in 51 cases without previous cesarean delivery (0.38 per 10,000) and 122 with previous cesarean delivery (21.1 per 10,000). The strongest risk factor was sequential labor induction with prostaglandins and oxytocin, compared with spontaneous labor, in those without previous cesarean delivery (adjusted odds ratio, 48.0, 95% confidence interval, 20.5-112.3) and those with previous cesarean delivery (adjusted odds ratio, 16.1, 95% confidence interval, 8

    To describe 3 near-full-term, young-adult felids (2 domestic shorthair cats, and 1 bobcat [Lynx rufus]) that experienced uterine rupture following trauma. Two of the animals had motor vehicular trauma and 1 had abdominal bite wounds. The 2 domestic cats that were treated with surgical exploration and ovariohysterectomy recovered uneventfully. The bobcat died during hospitalization prior to surgical intervention, and necropsy identified uterine rupture and associated peritonitis. Traumatic uterine rupture should be considered in known or suspected pregnant animals that experience blunt or penetrating trauma, particularly if they are in late-term pregnancy. © Veterinary Emergency and Critical Care Society 2016.

    Objective To characterize the labor of women attempting trial of labor after cesarean (TOLAC) who experience uterine rupture. Methods Secondary analysis of a nested case-control study of women attempting TOLAC. Women experiencing uterine rupture (cases) were compared to 2 reference groups, successful TOLAC and failed TOLAC. Interval censored regression was used to estimate the median time to progress 1-cm in dilation and the total time from 4–10-cm. Results 115 cases were compared to 341 successful TOLAC and 120 failed TOLAC. The time to progress 1-cm was similar between groups until 7-cm dilation. After 7-cm, cases of uterine rupture required longer to progress than successful TOLAC (median (95th percentile) (hrs) from 7–8-cm 0.38 (1.91) vs 0.16 (0.79), from 8–9-cm 0.28 (1.10) vs 0.10 (0.39)). Women with a uterine rupture had similar labor curves to those with a failed TOLAC. Conclusion Women with labor dystocia in the active phase of labor should be closely monitored for uterine rupture in TOLAC. PMID:22749410

  18. Spontaneous rupture on irregular faults

    2014-12-01

    It is now know (e.g. Robinson et al., 2006) that when ruptures propagate around bends, the rupture velocity decrease. In the extreme case, a large bend in the fault can stop the rupture. We develop a 2-D finite difference method to simulate spontaneous dynamic rupture on irregular faults. This method is based on a second order leap-frog finite difference scheme on a uniform mesh of triangles. A relaxation method is used to generate an irregular fault geometry-conforming mesh from the uniform mesh. Through this numerical coordinate mapping, the elastic wave equations are transformed and solved in a curvilinear coordinate system. Extensive numerical experiments using the linear slip-weakening law will be shown to demonstrate the effect of fault geometry on rupture properties. A long term goal is to simulate the strong ground motion near the vicinity of bends, jogs, etc.

    2014-01-01

    Spontaneous rupture of spleen due to malignant melanoma is a rare situation, with only a few case reports in the literature. This study reports a previously healthy, 30-year-old man who came with chief complaint of acute abdominal pain to emergency room. On physical examination, abdominal tenderness and guarding were detected to be coincident with hypotension. Ultrasonography revealed mild splenomegaly with moderate free fluid in abdominopelvic cavity. Considering acute abdominal pain and hemodynamic instability, he underwent splenectomy with splenic rupture as the source of bleeding. Histologic examination showed diffuse infiltration by tumor. Immunohistochemical study (positive for S100, HMB45, and vimentin and negative for CK, CD10, CK20, CK7, CD30, LCA, EMA, and chromogranin) confirmed metastatic malignant melanoma. On further questioning, there was a past history of a nasal dark skin lesion which was removed two years ago with no pathologic examination. Spontaneous (nontraumatic) rupture of spleen is an uncommon situation and it happens very rarely due to neoplastic metastasis. Metastasis of malignant melanoma is one of the rare causes of the spontaneous rupture of spleen. PMID:24795827

    Objective The purpose of this case series was to retrospectively examine records of cases with uterine rupture in pregnancies following myomectomy and to describe the clinical features and pregnancy outcomes. Methods This study was conducted as a multicenter case series. The patient databases at 7 tertiary hospitals were queried. Records of patients with a diagnosis of uterine rupture in the pregnancy following myomectomy between January 2012 and December 2014 were retrospectively collected. The uterine rupture cases enrolled in this study were defined as follows: through-and-through uterine rupture or tear of the uterine muscle and serosa, occurrence from 24+0 to 41+6 weeks’ gestation, singleton pregnancy, and previous laparoscopic myomectomy (LSM) or laparotomic myomectomy (LTM) status. Results Fourteen pregnant women experienced uterine rupture during their pregnancy after LSM or LTM. Preterm delivery of less than 34 weeks’ gestation occurred in 5 cases, while intrauterine fetal death occurred in 3, and 3 cases had fetal distress. Of the 14 uterine rupture cases, none occurred during labor. All mothers survived and had no sequelae, unlike the perinatal outcomes, although they were receiving blood transfusion or treatment for uterine artery embolization because of uterine atony or massive hemorrhage. Conclusion In women of childbearing age who are scheduled to undergo LTM or LSM, the potential risk of uterine rupture on subsequent pregnancy should be explained before surgery. Pregnancy in women after myomectomy should be carefully observed, and they should be adequately counseled during this period. PMID:27896247

    To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005-2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 women who had undergone repeat cesarean section were identified and their operation reports were reviewed. Descriptions of complete uterine rupture or uterine dehiscence in operation reports were compared with diagnoses registered in EPRS with International Classification of Diseases codes version 10 (ICD-10). Sensitivity and specificity of complete uterine rupture registration were calculated. There were 13 women with a registered diagnosis of uterine rupture. After reviewing medical records of women with repeat cesarean section, seven additional cases of complete uterine rupture, 33 cases of uterine dehiscence and 39 cases of extremely thin myometrium were identified. The incidence of complete uterine rupture and uterine dehiscence for women who delivered by repeat cesarean section was 2.8% and 10.1%, respectively. Diagnosis of complete uterine rupture was underreported in the EPRS by 35% and diagnosis of uterine dehiscence was missing in 100% of cases.

    The incidence of uterine malformations affecting reproduction is difficult to assess. Their identification requires a specific assessment (hysterosalpingography, hysteroscopy, laparoscopy). Spontaneous fertility can be affected depending on the type of uterine abnormality. All these abnormalities can affect the evolution of pregnancy causing early and late miscarriage, ectopic pregnancy, threat of premature labour, premature labour, vascular pathologies during pregnancy and inadequate intra-uterine growth. Bicornuate uterus is the most common uterine malformation and represents about half of all uterine anomalies The occurrence of this type of pregnancy is associated with an increased risk of maternal mortality, but early diagnosis and proper monitoring can lead pregnancies to term on malformed uterus. Ultrasound screening should allow for a systematic identification of such cases in order to take the necessary preventive measures. We report a case of uterine rupture in a patient with unicervical bicornuate uterus at 12 weeks of amenorrhea.

    Each year in the United States, approximately 60 percent of women with a prior cesarean delivery who become pregnant again attempt labor. Concern persists that a trial of labor may increase the risk of uterine rupture, an uncommon but serious obstetrical complication. We conducted a population-based, retrospective cohort analysis using data from all primiparous women who gave birth to live singleton infants by cesarean section in civilian hospitals in Washington State from 1987 through 1996 and who delivered a second singleton child during the same period (a total of 20,095 women). We assessed the risk of uterine rupture for deliveries with spontaneous onset of labor, those with labor induced by prostaglandins, and those in which labor was induced by other means; these three groups of deliveries were compared with repeated cesarean delivery without labor. Uterine rupture occurred at a rate of 1.6 per 1000 among women with repeated cesarean delivery without labor (11 women), 5.2 per 1000 among women with spontaneous onset of labor (56 women), 7.7 per 1000 among women whose labor was induced without prostaglandins (15 women), and 24.5 per 1000 among women with prostaglandin-induced labor (9 women). As compared with the risk in women with repeated cesarean delivery without labor, uterine rupture was more likely among women with spontaneous onset of labor (relative risk, 3.3; 95 percent confidence interval, 1.8 to 6.0), induction of labor without prostaglandins (relative risk, 4.9; 95 percent confidence interval, 2.4 to 9.7), and induction with prostaglandins (relative risk, 15.6; 95 percent confidence interval, 8.1 to 30.0). For women with one prior cesarean delivery, the risk of uterine rupture is higher among those whose labor is induced than among those with repeated cesarean delivery without labor. Labor induced with a prostaglandin confers the highest risk.

    Objective To estimate the risk of uterine rupture associated with labor induction in women attempting trial of labor after cesarean (TOLAC) accounting for length of labor. Methods Nested case-control study of women attempting TOLAC within a multicenter retrospective cohort study of women with a prior cesarean. Time-to-event analyses were performed with time zero defined as the first cervical exam of 4-cm. Subjects experienced the event (uterine rupture) or were censored (delivered). Results One-hundred-eleven cases of uterine rupture were compared to 607 controls. When accounting for length of labor, the risk of uterine rupture in induced labor was similar to spontaneous-onset labor (hazard ratio (HR) 1.52, 95% confidence interval (CI) 0.97-2.36). An initial unfavorable cervical exam was associated with an increased risk of uterine rupture compared to spontaneous (HR 4.09, 95% CI 1.82-9.17). Conclusion After accounting for labor duration, induction is not associated with an increased risk of uterine rupture in women undergoing TOLAC. PMID:22000899

    To estimate the effect of the onset of labor before a primary cesarean delivery on the risk of uterine rupture if vaginal birth after cesarean (VBAC) is attempted in the next pregnancy. Longitudinally linked birth records were used to follow women from a primary cesarean delivery to a trial of labor at term for their next birth. The effects of characteristics of both the trial of labor and primary cesarean deliveries on the risk of uterine rupture were examined. Of 10,160 women who had a trial of labor, 39 (0.38%) had a uterine rupture. Women who were induced or augmented for their trial of labor had a greater relative risk (RR) of uterine rupture (crude RR 4.24, 95% confidence interval [CI] 2.23-8.07). Women whose primary cesarean delivery was planned or followed induction of labor also had an increased risk of uterine rupture (crude RR 2.61, 95% CI 1.24-5.49), and this risk remained after adjustment for other factors. Women with a history of either spontaneous labor or vaginal birth had one uterine rupture for every 460 deliveries; women without this history who required induction or augmentation to proceed with a VBAC attempt had one uterine rupture for every 95 deliveries. Labor before the primary cesarean delivery can decrease the risk of uterine rupture in a subsequent trial of labor. A history of primary cesarean delivery preceded by spontaneous labor is favorable for VBAC. II.

    Combined uterine and urinary bladder rupture following prolonged obstructed labor is indeed a momentous uro-obstetric emergency. The urinary bladder involvement is distinctly rare in the absence of factors that predispose the bladder to be adherent to the lower uterine segment and is quite unusual in a primigravida. To report a rare case of uterine rupture involving urinary bladder secondary to a prolonged obstructed labor in a primigravida from a low resource setting. A 17-year-old married unbooked primigravida who presented with a 3-day history of spontaneous onset of labor at term that was initially managed at home and later in a primary health care center where she had fundal pressure and oxytocin augmentation, respectively. The labor was complicated by combined uterine and urinary bladder rupture with sepsis. She was resuscitated and had exploratory laparotomy with uterine and urinary bladder repair. The postoperative period was uneventful and she was followed-up at the gynecology and family planning clinics. There is a need for community reawakening on the inherent risks of teenage pregnancy, bad obstetric practices, and unsupervised pregnancy, labor, and delivery, particularly in the rural settings as in the index patient. A high index of suspicion and prompt appropriate intervention will reduce the sequel of morbidity and occasional mortality from this predicament.

    Caesarean section (CS) is increasing globally, and women with prior CS are at higher risk of uterine rupture in subsequent pregnancies. However, little is known about the incidence, risk factors, and outcomes of uterine rupture in women with prior CS, especially in developing countries. To investigate this, we conducted a secondary analysis of the World Health Organization Multicountry Survey on Maternal and Newborn Health, which included data on delivery from 359 facilities in 29 countries. The incidence of uterine rupture among women with at least one prior CS was 0.5% (170/37,366), ranging from 0.2% in high-Human Development Index (HDI) countries to 1.0% in low-HDI countries. Factors significantly associated with uterine rupture included giving birth in medium- or low-HDI countries (adjusted odds ratio [AOR] 2.0 and 3.88, respectively), lower maternal educational level (≤6 years) (AOR 1.71), spontaneous onset of labour (AOR 1.62), and gestational age at birth <37 weeks (AOR 3.52). Women with uterine rupture had significantly higher risk of maternal death (AOR 4.45) and perinatal death (AOR 33.34). Women with prior CS, especially in resource-limited settings, are facing higher risk of uterine rupture and subsequent adverse outcomes. Further studies are needed for prevention/management strategies in these settings. PMID:28281576

    Alkaptonuria (AKU) is a rare inborn metabolic disease characterized by accumulation of homogentisic acid (HGA). Excretion of HGA in urine causes darkening of urine and its deposition in connective tissues causes dark pigmentation (ochronosis), early degeneration of articular cartilage, weakening of the tendons, and subsequent rupture. In this case report, we present a rare case of a patient presented with unilateral spontaneous rupture of Achilles tendon due to AKU. The patient developed most of the orthopedic manifestations of the disease earlier than typical presentations. Alkaptonuria patients should avoid strenuous exercises and foot straining especially in patients developing early orthopedic manifestations. PMID:26620992

    We assessed the rate of uterine rupture in patients undergoing labor induction for attempted vaginal birth after cesarean (VBAC). A retrospective study was performed of data from a computerized database. Deliveries from January 1, 1998, to June 30, 2001, in the Southern California Kaiser Permanente system were reviewed and various perinatal characteristics analyzed. A total of 16,218 patients had a prior low transverse cesarean section. Of these, 6832 (42.1%) had a trial of labor. Successful VBAC occurred in 86% of patients with spontaneous onset of labor and 66% of patients with labor induction ( p < 0.001). The uterine rupture rate was not different between patients with spontaneous or induced labor (1.0% versus 1.2%, p = 0.51). Similarly, there was no significant difference between oxytocin or prostaglandin E2 induction (1.4% versus 1.0%, p = 0.59). In our study, labor induction did not appear to increase the risk of uterine rupture in women attempting VBAC. © Thieme Medical Publishers.

    Rupture of uterus is an obstetrical complication characterized by a breach in the uterine wall and the overlying serosa. We report an unusual case of spontaneous rupture of an unscarred uterus in a 33-year-old woman, a day after her third successful vaginal delivery. A 33-year-old pregnant woman, gravid 3, para 3, was referred to our department at 39 gestational week because of rupture of membranes. Despite tocolysis administration, her pregnancy was delivered vaginally after 2 days, giving birth to a male neonate of 3,020 g with normal Apgar scores at first and fifth minute. Her uterus was intact and gynecological examination after delivery was normal without any potential signs or symptoms of pathology. However, the day following her labor, patient complained of left iliac fossa pain. Her blood tests revealed a CRP value at 27.6 mg/L, whereas the X-rays revealed an extensive impacted fecal mass in the colon. MRI revealed that the left lower myometrial part of the uterus was depicted abrupt, with simultaneous presence of hemorrhagic stuff. The decision of laparotomy was therefore made in order to further evaluate rupture of uterus and properly treat patient. And subtotal hysterectomy was performed. Postoperative follow-up period was not characterized by any complications and patient was finally discharged 4 days after hysterectomy. PMID:25368704

    Choriocarcinoma is a rare neoplasm and a malignant form of gestational trophoblastic disease. Choriocarcinoma is frequently preceded by a complete mole, ectopic pregnancy, nonmolar intrauterine abortion, and uncommonly by a partial mole. It is treated medically with chemotherapeutic drugs usually. However, we managed to save a life with appropriate and timely surgical intervention in a case of choriocarcinoma who presented with uterine rupture, haemoperitoneum, anaemia and hypovolemic shock. The patient underwent exploratory laparotomy and hysterectomy followed by systemic chemotherapy. PMID:26557535

    Background. Uterine fibroids are common benign tumors in women. Clinical manifestations are well known. Acute complications necessitating emergent surgical intervention are rare. Case. We report a case of a 53-year-old woman with a history of uterine fibroids presenting with acute-onset severe abdominal pain. Imaging indicated massive free fluid and a large partially solid uterine mass. Vitals were consistent with hypovolemic shock. Examination revealed a surgical abdomen. She underwent an emergent laparotomy and total hysterectomy. Surgery revealed 4.5 L of hemoperitoneum and a 15 cm degenerated uterine fibroid with active bleeding. Pathology was consistent with intraoperative findings. She required transfusion of numerous blood products perioperatively. Her postoperative course was uncomplicated. Conclusion. It is rare for a uterine fibroid to spontaneously rupture. However, prompt recognition of this severe complication is critical for expeditious, life-saving surgical management. PMID:28127487

    This study was carried out in the Department of Obstetrics and Gynaecology of the Mahatma Gandhi Institute of Medical Sciences, Sevagram in Central India. In the 12 years between 1989 and 2000 a total of 16 cases of ruptured uterus were managed, the incidence of rupture of the pregnant uterus being 0.62 per 1000 births. One-quarter of the cases occurred between 1983 and 1988. No teenager or elderly woman (over 40) or grandmultipara sustained a uterine rupture. Four women had a rupture of a previous scar. In five rupture had occurred in association with malpresentations, one was a case of hydrocephalus, two had a morbidly adherent placenta praevia and four had a normal presentation, with lack of progress in labour. Two of these 16 women had twins. One had come with a retained second twin with transverse lie and the other was a booked case with multiple problems, including a previous caesarean section, present twin pregnancy and placenta praevia accreta and she died. This was the only maternal death. Perinatal mortality was 77.77% compared to 5.88% maternal and 100% perinatal mortality in the cases reported previously between 83 and 88, from the same institution. Overall, there is some improvement in perinatal survival and one-quarter incidence of rupture of the pregnant uterus.

    We present the case of a 37-year-old lady who presented with severe colicky left sided flank pain associated with vomiting, chills and rigors. A non-contrast Computed Tomography of the Kidney Ureter and Bladder was performed which showed a 2–3 mm stone in the pelvic part of the left ureter. Following 2 days of conservative treatment she was still complaining of increasingly severe pain. A contrast computed tomography of the abdomen was performed which was suggestive of a perforation of the left collecting system. A diagnosis of spontaneous left proximal ureteric perforation secondary to urolithiasis was made. We opted to treat her with retrograde endoscopic ureteric stent insertion. Spontaneous rupture of the ureter is a relatively rare urological occurrence with only a small number of cases reported in the literature. Although there are no recommendations, ureteric double-J stenting is the most commonly used management option with good results reported. PMID:28069871

    A case of uterine prolapse coexisting with uterine horn rupture in a 3-year-old Portuguese Podengo bitch, which is an uncommon occurrence, is described. The female was presented with a history of recent parturition, with delivery of four healthy puppies that were normally tended and nursed. The situation developed after an uneventfully pregnancy, and no direct causative factor was identified. The duration of the prolapse was unknown, but considered to be recent because of the swollen reddish appearance of the tubular everted mass. No foetus was found in the uterus or the abdominal cavity. The female was presented in good physical condition, without signs of shock or haemorrhage. During surgical treatment, the uterus was replaced to its normal position followed by ovary-hysterectomy at 12 h from admittance. © 2011 Blackwell Verlag GmbH.

    Pyometra is collection of pus within the uterine cavity and is usually associated with underlying gynaecological malignancy or other benign causes. Spontaneous rupture of pyometra is a rare complication. We report a case of a 65-year-old female who presented with acute abdomen and was diagnosed with a ruptured uterus secondary to pyometra and consequent peritonitis on dynamic transvaginal sonography (TVS) which was later confirmed on contrast enhanced computed tomography (CECT). An emergency laparotomy was performed and about 800 cc of pus was drained from the peritoneal cavity. A rent was found in the anterior uterine wall and hence hysterectomy was performed. Histopathology revealed mixed inflammatory cell infiltrate with no evidence of malignancy. There are only 31 cases of ruptured pyometra reported till date, most of which were definitively diagnosed only on laparotomy. In only two of these cases the preoperative diagnosis was made on CECT. We report this case, as the correct and definitive diagnosis was made preoperatively on dynamic TVS. To our knowledge, this is the first case report revealing spontaneous ruptured pyometra being diagnosed preoperatively on dynamic TVS. This report is aimed at giving emphasis on the use of simple dynamic TVS for accurate diagnosis of rare spontaneous ruptured pyometra causing peritonitis.

    To assess the risk of uterine rupture (UR) in attempted vaginal birth after cesarean and to identify risk factors. Systematic review by consulting the following databases: PubMed (MEDLINE), Cochrane Library Plus, Embase, Nursing@Ovid, Cuidatge and Dialnet. The search was conducted between January and March 2015. MeSH descriptors used were: vaginal birth after cesarean; uterine rupture; labor induced and labor obstetric or trial of labor. There were no restrictions on date or language. The selection of articles was performed by 2 independent reviewers, standardized and unblinded. A critical review of the summary was conducted, and if was necessary, the full text was consulted. Prospective and retrospective documents were included. A total of 39 documents were included for their relevance and interest. Few clinical trials were found. The UR incidence on the results of the studies analyzed ranged from 0.15-0.98% in spontaneous labor; 0.3-1.5% in stimulation and induction with oxytocin, and 0.68-2.3% in prostaglandin inductions. The success of vaginal birth after cesarean is important and improves when conditions are optimal. However it is not without risks, the main one being UR. Induction of labor with oxytocin and/or prostaglandins appears as the main risk factor, while the spontaneous onset of labor and a prior vaginal birth are protective factors.

    A Great Dane bitch was treated for presumed primary uterine inertia with repeated doses of oxytocin and manually assisted whelping. She was diagnosed with uterine rupture and septic peritonitis the following day. The uterine rupture is hypothesized to have occurred as a result of the management strategy used to treat dystocia. The dog underwent ovariohysterectomy, and the septic peritonitis was managed with open peritoneal drainage. The dog recovered well and was discharged 5 days later. No previous reports of canine uterine rupture associated with manual intervention appear to have been published. This report highlights the potential dangers involved in such an approach.

    The relationship between abortion and uterine fibroids has received little attention. The aim of the present study was to explore the association between number of induced and spontaneous abortions and the risk of uterine fibroids in middle-aged and older Chinese women. A total of 14,595 retired female employees from the Dongfeng-Tongji cohort study were included in our analysis. Information on induced and spontaneous abortions was collected by trained interviewers through face-to-face interviews. Diagnosis of uterine fibroids was based on ultrasound or self-reported physician diagnosis of uterine fibroids. Logistic regression models were used to explore the associations between number of induced and spontaneous abortions and the risk of uterine fibroids. The prevalence of uterine fibroids was 15.1% among all participants. Higher number of induced abortions was associated with an increased risk of uterine fibroids (1 induced abortion: odds ratios [ORs] = 1.32, 95% confidence interval [CI] 1.18-1.48; 2 induced abortions: OR = 1.45, 95% CI 1.28-1.64; and ≥3 induced abortions: OR = 1.62, 95% CI 1.39-1.90). Compared with women without induced abortion, ORs for women with 1, 2, and ≥3 were 1.17 (95% CI 1.03-1.32), 1.21 (95% CI 1.06-1.39), and 1.36 (95% CI 1.15-1.61), respectively, after adjustment for potential confounders. No association was observed between the number of spontaneous abortions and the risk of uterine fibroids. The findings of this study showed that induced abortion may be an independent risk factor for uterine fibroids in middle-aged and older Chinese women.

    Spontaneous renal bleeding mainly occurs in patients with polycystic kidney diseases or cancer. Indeed, despite the high prevalence of simple cysts, their spontaneous atraumatic rupture is a rare event. Underlying mechanisms may involve the increase of intracystic pressure and/or the development of a haemorrhage into the cyst. Management of this condition includes surgery, interventional radiology or conservative strategies. Here, we report a case of spontaneous rupture of a simple renal cyst, successfully managed with conservative treatment.

    Uterine rupture is an obstetric calamity with surgery as its management mainstay. Uterine repair without tubal ligation leaves a uterus that is more prone to repeat rupture while uterine repair with bilateral tubal ligation (BTL) or (sub)total hysterectomy predispose survivors to psychosocial problems like marital disharmony. This study aims to evaluate obstetricians' perspectives on surgical decision making in managing uterine rupture. A questionnaire-based cross-sectional study of obstetricians at the 46th annual scientific conference of Society of Gynaecology and Obstetrics of Nigeria in 2012. Data was analysed by descriptive and inferential statistics. Seventy-nine out of 110 obstetricians (71.8%) responded to the survey, of which 42 (53.2%) were consultants, 60 (75.9%) practised in government hospitals and 67 (84.8%) in urban hospitals, and all respondents managed women with uterine rupture. Previous cesarean scars and injudicious use of oxytocic are the commonest predisposing causes, and uterine rupture carries very high incidences of maternal and perinatal mortality and morbidity. Uterine repair only was commonly performed by 38 (48.1%) and uterine repair with BTL or (sub) total hysterectomy by 41 (51.9%) respondents. Surgical management is guided mainly by patients' conditions and obstetricians' surgical skills. Obstetricians' distribution in Nigeria leaves rural settings starved of specialist for obstetric emergencies. Caesarean scars are now a rising cause of ruptures. The surgical management of uterine rupture and obstetricians' surgical preferences vary and are case scenario-dependent. Equitable redistribution of obstetricians and deployment of medical doctors to secondary hospitals in rural settings will make obstetric care more readily available and may reduce the prevalence and improve the outcome of uterine rupture. Obstetrician's surgical decision-making should be guided by the prevailing case scenario and the ultimate aim should be to avert

    Reports of uterine rupture following surgical abortion are rare but may result in hemorrhage, sepsis, and even death. In this unique case, we describe how a transabdominal pelvic ultrasound performed at the bedside by an emergency department physician identified uterine rupture with retained products of conception and led to an emergent laparotomy and hysterectomy. This case illustrates how bedside ultrasound may be used in patients presenting with abdominopelvic pain following surgical abortion to shorten the time to definitive treatment and ultimately lower the morbidity and mortality associated with a diagnosis of life-threatening uterine rupture.

Awareness on the part of the treating surgeon that bladder rupture is a possibility will lead to an early diagnosis. Immediate exploration, removing urine from the peritoneal cavity or retropubic space, closing the rupture and securing good vesical drainage, results in resumption of vesical function, and thereby decreases the mortality and morbidity.

    Craniopharyngioma is a relatively benign intracranial tumour that involves sellar and supra-sellar regions. Spontaneous rupture of craniopharyngioma into the sub-arachnoid space or into the ventricles is a rare phenomenon and few cases are reported in literature. We hereby report a case of sellar-suprasellar craniopharyngioma with focal intra-parenchymal rupture into brain causing aggravation of headache in a 12-year-old female child. This complication is a relatively rare phenomenon, which requires attention for early intervention. This was managed by trans-nasal endoscopic trans-sphenoidal surgery. Usually rupture of craniopharyngioma causes chemical meningitis or it can be asymptomatic. Sometimes rupture can cause complete resolution of cyst and symptoms. In the present case, there was only focal rupture and it was into brain parenchyma causing brain oedema with aggravation of headache. Magnetic Resonance Imaging (MRI) in intra-parenchymal rupture of craniopharyngioma has been emphasized in this case report.

  18. Lived experiences of women who developed uterine rupture following severe obstructed labor in Mulago hospital, Uganda

    2014-01-01

    Background Maternal mortality is a major public health challenge in Uganda. Whereas uterine rupture remains a major cause of maternal morbidity and mortality, there is limited research into what happens to women who survive such severe obstetric complications. Understanding their experiences might delineate strategies to support survivors. Methods This qualitative study used a phenomenological approach to explore lived experiences of women who developed uterine rupture following obstructed labor. In-depth interviews initially conducted during their hospitalization were repeated 3–6 months after the childbirth event to explore their health and meanings they attached to the traumatic events and their outcomes. Data were analyzed using thematic analysis. Results The resultant themes included barriers to access healthcare, multiple “losses” and enduring physical, psychosocial and economic consequences. Many women who develop uterine rupture fail to access critical care needed due to failure to recognise danger signs of obstructed labor, late decision making for accessing care, geographical barriers to health facilities, late or failure to diagnose obstructed labor at health facilities, and failure to promptly perform caesarean section. Secondly, the sequel of uterine rupture includes several losses (loss of lives, loss of fertility, loss of body image, poor quality of life and disrupted marital relationships). Thirdly, uterine rupture has grim economic consequences for the survivors (with financial loss and loss of income during and after the calamitous events). Conclusion Uterine rupture is associated with poor quality of care due to factors that operate at personal, household, family, community and society levels, and results in dire physical, psychosocial and financial consequences for survivors. There is need to improve access to and provision of emergency obstetric care in order to prevent uterine rupture consequent to obstructed labor. There is also

    To determine the risk of uterine rupture when using misoprostol for second-trimester abortion in women with a history of cesarean delivery. MEDLINE, EMBASE, CINAHL, LILACS, and the Cochrane Library were searched systematically for all articles published before September 2008. Sixty-three articles were found using the above data sources. I excluded case reports, narrative reviews or commentaries, studies that excluded women with a history of cesarean delivery, studies with unrelated outcomes, studies not conducted in humans, and studies that were not available in English. The remaining 16 studies that described misoprostol use for second-trimester abortion in women with a history of cesarean delivery were examined. The number of participants with and without cesarean delivery, regimen of medical abortion used, and cases of uterine rupture were reviewed. To estimate the risk of uterine rupture in women with prior cesarean delivery undergoing second-trimester abortion with misoprostol and number needed to harm, I pooled the results of all 16 studies. The risk of uterine rupture in women with prior cesarean delivery was 0.28% (95% confidence interval [CI] 0.08-1.00%). The risk of uterine rupture in women without prior cesarean delivery was 0.04% (95% CI 0.01-0.20%). Based on these risks, if 414 women with a history of cesarean delivery were given misoprostol for second-trimester abortion, one would experience uterine rupture. The risk of uterine rupture among women with a prior cesarean delivery undergoing second-trimester abortion using misoprostol is less than 0.3%. This may be acceptable to both patients and providers.

    Imperforate hymen is the most frequent congenital malformation of the female genital tract and usually remains asymptomatic until puberty. The diagnosis of this malformation is rarely made at birth and surgical treatment is often by hymenotomy. However, spontaneous rupture of the imperforate hymen is possible but is very rare. We report two cases of imperforate hymen revealed by mucocolpos at birth. Ultrasound examination does not objectify hydrocolpos or hydrometrocolpos. Spontaneous rupture of the imperforate hymen was observed respectively in the 4th and 7th day of life with a satisfactory result at 1 month of age. Screening for the imperforate hymen must be systematic at birth to offer early hymenotomy if the spontaneous rupture is not adequate and prevent serious complications of the disease at puberty.

    2012-01-01

    We report a case of the female patient who was admitted to the hospital because of syncope experienced while climbing stairs. Diagnostic workup raised the suspicion of a right diaphragmatic rupture that was eventually confirmed by surgery (right-sided thoracotomy). Surgery also revealed tissue protruding through the rupture site from within the retroperitoneum that was proven subsequently to be a dedifferentiated liposarcoma. Second surgery was performed to completely remove the liposarcoma tissue and repair a coincident old right lumbar region hernia. The patient recovered fully. Spontaneous rupture of the diaphragm is rare and this is especially true for the right hemidiaphragm. We report the first case of diaphragmatic rupture caused by local infiltration by a retroperitoneal liposarcoma. This and similar reports emphasise that in cases with high clinical suspicion of diaphragmatic rupture, diagnosis should be pursued even in the absence of a preceding traumatic event. PMID:22524913

    A 54-year-old woman who had been treated for rheumatoid arthritis for 12 years developed spontaneous multiple flexor tendon ruptures during a 5-month period. Radiography revealed volar subluxation of the lunate bone. Surgery was performed 5 months after the first onset of tendon rupture. All eight flexors, except the flexor pollicis longus tendons, had ruptured, and the damage resembled spaghetti. Four flexor digitorum profundus tendons were reconstructed by bridge graft using their respective sublimis tendons. Wrist joint fusion and tenolysis were performed 3 months after the first operation. Each finger achieved a good range of motion 2 years and 6 months after the second operation.

    2012-01-01

    Background Recent reports of the risk of morbidity due to uterine rupture are thought to have contributed in some countries to a decrease in the number of women attempting a vaginal birth after caesarean section. The aims of this study were to estimate the incidence of true uterine rupture in the UK and to investigate and quantify the associated risk factors and outcomes, on the basis of intended mode of delivery. Methods and Findings A UK national case-control study was undertaken between April 2009 and April 2010. The participants comprised 159 women with uterine rupture and 448 control women with a previous caesarean delivery. The estimated incidence of uterine rupture was 0.2 per 1,000 maternities overall; 2.1 and 0.3 per 1,000 maternities in women with a previous caesarean delivery planning vaginal or elective caesarean delivery, respectively. Amongst women with a previous caesarean delivery, odds of rupture were also increased in women who had ≥ two previous caesarean deliveries (adjusted odds ratio [aOR] 3.02, 95% CI 1.16–7.85) and <12 months since their last caesarean delivery (aOR 3.12, 95% CI 1.62–6.02). A higher risk of rupture with labour induction and oxytocin use was apparent (aOR 3.92, 95% CI 1.00–15.33). Two women with uterine rupture died (case fatality 1.3%, 95% CI 0.2–4.5%). There were 18 perinatal deaths associated with uterine rupture among 145 infants (perinatal mortality 124 per 1,000 total births, 95% CI 75–189). Conclusions Although uterine rupture is associated with significant mortality and morbidity, even amongst women with a previous caesarean section planning a vaginal delivery, it is a rare occurrence. For women with a previous caesarean section, risk of uterine rupture increases with number of previous caesarean deliveries, a short interval since the last caesarean section, and labour induction and/or augmentation. These factors should be considered when counselling and managing the labour of women with a previous

    To clarify the effects on uterine arterial flow velocity waveforms of uterine contractions following oxytocin infusion and during spontaneous labor. Uterine arterial flow velocity waveforms were obtained by pulsed Doppler methods from 22 women during an oxytocin challenge test (OCT), 26 women during oxytocin-induced labor, and 40 women during spontaneous labor. Mean resistance index (RI) for bilateral arteries was used for analyses. After the onset of labor, flow velocity waveforms were assessed according to cervical dilatation. During OCT, Doppler flow velocimetry was performed when three uterine contractions occurred per 10-min period. RI values did not differ significantly between induced and spontaneous labor during relaxations at any level of cervical dilatation. However, during contractions, RI was significantly higher for induced labor than for spontaneous labor. Absence or reversal of flow was more frequent in the OCT group than in the induced labor group (P < 0.0001). However, no significant differences were found between spontaneous and induced labor groups. Interactions between the contracting uterine body and the relaxing lower segment in oxytocin-induced labor might be associated with differences in uterine arterial flow during contraction between oxytocin-induced and spontaneous labor. However, changes in the intensity of uterine contractions during labor progression might differ between oxytocin-induced and spontaneous labor.

    Introduction Spontaneous splenic rupture is a rare but dangerous event that requires prompt diagnosis and frequently an emergency splenectomy. Previous case reports have described the occurrence in patients with medical conditions, anticoagulant treatments, endoscopic procedures, laparoscopic surgery or no particular predisposing factor. Our report is the first to describe the occurrence of spontaneous spleen rupture following a laparotomy conducted in the lower abdomen. Case History A 62-year-old woman presented with a 10-day history of right iliac fossa pain radiating to the right leg and associated vomiting. Following a routine blood check and computed tomography (CT), she underwent an open appendicectomy through a lower midline laparotomy for an appendicular abscess. Four days later, she experienced haemorrhagic shock and a second CT scan diagnosed a spontaneous splenic rupture that required a prompt splenectomy. Conclusions Our case is the first that describes the spontaneous rupture of the spleen following an open procedure conducted in the lower quadrants. This entity must still be considered as a rare but potential cause for postoperative bleeding when no other obvious sources are identified. PMID:25723677

    We encountered a rare case of spontaneous rupture of the omental artery. A 25-year-old man without any episode of abdominal trauma or bleeding disorders came to the emergency unit with left upper abdominal pain. Hematoma with extravasation of the greater omentum and a hemoperitoneum was confirmed on abdominal contrast-enhanced computed tomography. Bleeding from the omental artery was suspected based on these findings. Transcatheter arterial embolization was successfully performed after extravasation of the omental artery, which arises from the left gastroepiploic artery, was confirmed on arteriography. Partial ometectomy was performed 10 days after transcatheter arterial embolization, revealing that the hematoma measured 10 cm in diameter in the greater omentum. Pathological examination showed rupture of the branch of an omental artery without abnormal findings, such as an aneurysm or neoplasm. Thus, we diagnosed him with spontaneous rupture of the omental artery. The patient recovered and was discharged from the hospital 10 days after the surgery, with a favorable postoperative course.

    Birth defects of the female genital tract are relatively common and often asymptomatic. Despite the pregnancy outcome can be favorable, adverse obstetric outcomes are described in women with uterine malformations. The authors report the case of an obstetric emergency which enhances the possibility of a very adverse and rare outcome of uterine rupture in a left hemi-cavity of a bicornuate uterus away from the term, at 18 weeks of pregnancy, in a pregnant woman with history of caesarean in the right hemi-cavity and with placenta increta. A malformed uterus with a primitive type cavity has lower distensibility of the wall with the progression of the pregnancy and facilitates the development of abnormal placentation forms, increasing the risk of uterine rupture in the first and second trimesters. The knowledge of the existence of a congenital uterine anomaly in the preconceptional period is of primary importance.

    Background. Heterotopic pregnancy is a multiple gestation with both intrauterine and ectopic fetuses. A cesarean scar ectopic pregnancy is when the fetus has implanted over the previous hysterotomy site. A known complication of cesarean scar ectopic pregnancy is uterine rupture, which can cause great morbidity and mortality. Case. 28-year-old G5P3105 at 10 weeks with a dichorionic diamniotic gestation was found to have a ruptured uterus with expulsion of a cesarean scar ectopic pregnancy and retention of the intrauterine fetus. After uterine repair, the singleton gestation reached viability was delivered by emergent cesarean section for placental abruption. Conclusion. Safe management of cesarean ectopic pregnancy requires early diagnosis by ultrasonography. With early detection, management can focus on preventing maternal morbidity of uterine rupture and life-threatening hemorrhage. PMID:28116191

    Uterine arteriovenous malformation (AVM) can cause massive hemorrhage and is often treated with uterine artery embolization (UAE), which may lead to ovarian insufficiency. Thus, avoiding UAE should be considered, particularly in women undergoing fertility treatments. We present three women diagnosed with postmiscarriage AVM on color Doppler by transvaginal ultrasound imaging. They had no genital bleeding and a small mass, measuring 16–22 mm. If estradiol was >300 pg/mL when AVM was diagnosed, then a gonadotropin-releasing hormone agonist was administered. All three women underwent follow-up observation, revealing spontaneous mass disappearance. To avoid ovarian insufficiency risk with UAE, conservative management and close follow-up observation should be considered in patients with AVM without bleeding, particularly during the fertility treatment.

    Spontaneous film rupture from van der Waals instability is investigated in 2D. A thin liquid film between adjacent bubbles in a foam has finite length, curved boundaries (Plateau borders), and a drainage flow from capillary suction that causes thinning. A full linear stability analysis of this thinning film shows that rupture occurs once the film has thinned to tens of nanometers. Whereas, in an unbounded, quiescent, flat free film, rupture occurs when the thickness is hundreds of nanometers. Finite length, Plateau borders and flow are all found to contribute to the stabilization. The drainage flow leads to several distinct qualitative features as well. In particular, unstable disturbances are advected by the flow to the edges of the thin film. As a result, the edges of the film close to the Plateau borders are more susceptible to rupture that the center of the film.

  18. Antepartum uterine rupture in previous caesarean sections presenting as advanced extrauterine pregnancies: lessons learnt.

    PubMed

    2009-03-01

    In present day obstetric practice, rupture of a previously scarred uterus should be uncommon. It occurs in <1% of previous caesarean sections and most cases occur during labour and have evidence of abnormal fetal heart rate patterns, vaginal bleeding and continuous abdominal pains. Clinicians are alert to these symptoms and signs, and therefore immediate action is taken to prevent further maternal morbidity and mortality. However, rupture of a previously scarred uterus may occur occasionally in the antepartum period. In such circumstances, the patients may be haemodynamically stable and present with loss of fetal movements and vague abdominal pains, and are treated expectantly for a period of time because an initial diagnosis of advanced extra-uterine pregnancy is made. We present a series of 7 cases, all of whom had one or more previous caesarean sections, were haemodynamically stable and were being managed expectantly, to illustrate the fact that ruptured uterus should be strongly considered in the differential diagnosis, even when the clinical signs and sonography are suggestive of an advanced extra-uterine pregnancy. The lessons in these cases fall into the following categories: 1. Ruptured uteri can occur in non-labouring women with previous lower segment caesarean sections. 2. Absence of signs of peritonism is possibly due to the fact that the pregnancy is extruded through the uterine rupture with the amniotic sac being intact and there is little or no bleeding into the abdominal cavity or vaginally. 3. Imaging techniques should focus on the size of the uterus, as an enlarged uterus in the background of an advanced extra-uterine pregnancy in a previously scarred uterus is highly suggestive of uterine rupture. Clinicians must strongly consider ruptured uteri in non labouring women with previous caesarean sections even when imaging modalities suggest an advanced extrauterine pregnancy. This will lead to earlier surgical treatment and appropriate information

    Background Spontaneous flexor tendon rupture is considered to be invariably associated with previous hand/wrist injury or systemic disease such as rheumatoid arthritis. Case Description A 54-year-old man presented with a 4-month history of mild ulnar wrist pain and spontaneous left little finger flexion loss in the absence of distant/recent trauma and systemic arthropathy. Surgical exploration confirmed a zone IV left little finger flexor digitorum profundus (FDP5) attritional rupture (100%), ring finger flexor digitorum profundus (FDP4) attenuation (40%) and a disrupted lunotriquetral ligament and volar-ulnar wrist capsule. Volar subluxation of the narrowed carpal tunnel resulted in flexor tendon attrition against the hamate hook. A side-to-side tendon transfer was performed along with a lunotriquetral ligament repair and temporary Kirschner wire fixation. At 6 months the patient had full active, synchronous flexion of the ring and little fingers and reduced wrist pain. Literature Review Traumatic flexor tendon ruptures have been reported following distal radius/hamate hook fractures, from carpal bone osteophytes, accessory carpal bones and intraosseous ganglia. Attritional ruptures caused by chronic, degenerative carpal pathology are less common. Clinical Relevance This case highlights an unusual cause of flexor tendon rupture due to chronic carpal instability. PMID:25032080

    Context: Spontaneous forniceal rupture is one of the possible complications of urolithiasis. The mechanism of forniceal rupture is not well explained in the literature. Most of the cases presented with sudden onset of acute renal colic and diagnosed by noncontrast CT (NCCT). Until now there is no solid consensus about the ideal management of such a condition. Aim: To study indications and validity of conservative management of spontaneous caliceal rupture. Settings and Design: This is an observational prospective study. Materials and Methods: All cases diagnosed as spontaneous forniceal rupture in our departments from 2011 to 2015 were enrolled. All cases were diagnosed with NCCT or CT-Urography.. Non complicated patients were primarily managed conservatively. Intervention (DJ stent insertion, nephrostomy tube insertion, or urgent ureteroscopy) was reserved to complicated cases or solitary kidney. Drainage of urinoma was done in cases with sizable urinoma (more than 100 ml3). Results: A total of 40 patients: Twenty eight (70%) patients had normal serum creatinine level at presentation, while 12 (30%) patients had elevated serum creatinine. Twenty three (57.5%) patients were successfully managed conservatively, their mean size of stone was 6.2 ± 2 mm and the hospital stay was 3.1 ± 1.9 days. Eighteen patients (42.5%) underwent interventions. Their stone size was 4.5 ± 2.1 mm and the hospital stay for the interventional group was 4.2 ± 1.8 days. Statistical Analysis Used: Mann-Whitney test was used for testing difference between means because the data groups are not parametric. Otherwise, simple descriptive statestics were used. Conclusion: Spontaneous forniceal rupture is more likely to occur with smaller distal ureteric stones. Conservative management is a valid option in non-complicated cases. Intervention should be reserved to complicated cases or cases with sizable urinoma. PMID:28216928

    Spontaneous rupture of hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE) is a rare and life-threatening complication. Pathophysiologic mechanisms are not yet fully known; it is suggested that rupture is preceded by reactive tissue edema and intratumerous bleeding, leading to a rapid expansion of tumour mass with risk of extrahepatic bleeding in the case of subcapsular localisation. This case report discusses a sudden, unexpected lethal complication in a 74 year-old male patient treated with TACE using DC Bead loaded with doxorubicin (DEBDOX) in a progressive multifocal HCC.

    Polyarteritis nodosa (PAN) is one of the systemic vasculitis that affects the media wall of arteries of small and medium diameter. Diagnosis proves difficult due to the unspecific symptoms that dominate the clinical profile. Liver involvement is very diverse, ranging from the development of cirrhotic liver disease to acute abdomen presentation that requires surgery because of liver rupture. The management of these patients requires an expert multidisciplinary team. There are several cases in the literature that describe a sudden liver rupture as the first manifestation of a PAN. In this paper we present the case of a 75 years old patient without any previous disease, who is subjected to major hepatic resection for spontaneous liver rupture. PMID:27917267

    Although rare, trauma in pregnancy can cause uterine rupture. In a periviable pregnancy, uterine rupture can lead to premature delivery and significant morbidity. A 29-year-old woman with four prior CSs presented with uterine rupture and a protruding morbidly adherent placenta at 23+4 weeks of gestation. Since the pregnancy was highly desired, the defect was repaired and the decision made to continue with the pregnancy. The patient presented at 29+3 weeks of gestation with preterm labour and subsequently delivered a healthy male infant of 1130 grams. Expectant management followed by CS can be beneficial in certain cases of uterine rupture with morbidly adherent placenta following trauma. This is especially the case in a periviable pregnancy, since prolonging the pregnancy will improve neonatal outcomes. We recommend individualized management based on clinical presentation, imaging findings, and the patient's wishes.

HEH has variable malignant potential, and the clinical diagnosis remains challenging. Here we report a case of HEH with spontaneous rupture. A 44-year-old man presented with constant cutting pains over the right upper abdomen after eating. He had hemoptysis 11 d previously. Diagnostic abdominal puncture demonstrated active bleeding. Chest and abdominal computer tomography scan showed multiple ground-glass nodules over the lungs, multiple low-density intrahepatic nodules and massive hemorrhage. Transcatheter arterial embolization and exploratory laparotomy were performed and subsequent immunohistochemical examination confirmed a diagnosis of HEH. PMID:28104995

    Spontaneous, nontraumatic retroperitoneal hemorrhage or Wunderlich syndrome (WS) is a rare but potential life-threatening condition. In most patients a bleeding renal neoplasm is the cause of the retroperitoneal hematoma. The management of this condition includes a conservative approach in the hemodynamically stable patients and active treatment in the unstable patients. Active treatment includes angioembolization or surgery. If angioembolization is not available open surgery is in most cases the preferred approach. We present a patient with a spontaneously ruptured kidney due to a central renal angiomyolipoma, which was treated by laparoscopic nephrectomy. PMID:25852958

    The work studies effects of various doses of oxytocin (0.01, 0.1, 1 and 10 microg/kg) on duration of discharges of spontaneous electrical activity and frequency of spikes in various parts of uterine tubes and of uterine body of non-pregnant rats. Under these conditions, changes in these parameters for ovarian parts of the uterine tubes had similar character unlike those in cervical parts of the tubes and in the middle part of the uterine body, so the latter parts can be grouped together owing to peculiarities of their changes. The longest duration of genesis of electric discharges has been shown for the ovarian part of uterine tubes at a concentration of 10 microg/kg of oxytocin. Morphological experiments revealed that among all studies areas the ovarian parts of uterine tubes were characterized by the highest amount of atypical cells that have the maximally pronounced functional activity.

    Plantar fascia rupture is an occasional complication in patients with chronic plantar fasciitis or in patients with plantar fasciitis treated with steroid injection. Very few cases of spontaneous plantar fascia rupture have been reported in the literature (Herrick and Herrick, Am J Sports Med 1983;11:95; Lun et al, Clin J Sports Med 1999;9:48-9; Rolf et al, J Foot Ankle Surg 1997;36:112-4; Saxena and Fullem, Am J Sports Med 2004;32:662-5). Spontaneous medial plantar fascia rupture in a 37-yr-old man with no preceding symptoms or steroid injections was confirmed with diagnostic ultrasound, which revealed severe fasciitis at the calcaneal insertion with partial tearing. After conservative treatment, the patient returned to full activities. We discuss the anatomy, risk factors, examination findings, and treatment for this condition, as well as the unique benefits that ultrasound offers over magnetic resonance imaging. It is important to consider plantar fascia rupture in patients with hindfoot pain and medioplantar ecchymosis, particularly if an injury occurred during acceleration maneuvers. Ultrasound in these cases can be used to diagnose a plantar fascia tear quickly, accurately, and cost-effectively.

    Spontaneous splenic rupture is a rare but known complication of dengue fever. Previously reported cases have occurred early during the course of the disease and most cases have led to a fatal outcome. Here we report a case of spontaneous splenic rupture in a patient with dengue fever, which occurred during the recovery phase of the illness. A 28-year-old Sinhalese, Sri Lankan man presented with a history of fever, myalgia and vomiting of 4 days duration. Investigations revealed a diagnosis of dengue fever with no signs of plasma leakage. He was managed in the ward as per local protocol. During the recovery phase the patient developed severe abdominal distention with circulatory failure. Radiology revealed splenic rupture with massive amounts of abdominal free fluid. The patient was resuscitated and Emergency laparotomy with splenectomy was performed. The outcome was excellent with the patient making a complete recovery. Although splenic rupture is a known complication of dengue fever it may be manifested late in the disease process. A high degree of suspicion should be maintained and patients must be monitored even during the recovery phase of dengue fever. Early diagnosis and intervention can prevent mortality.

    Spontaneous rupture of the bladder is a rare event. The clinical presentation shows the signs and symptoms of peritonitis, but the diagnosis is made at the operating table. This event is burdened with a high mortality rate. We present a case report of a 73-year-old man who came to our observation. He was a chronic carrier of urinary catheter, at least 7 times removed traumatically by himself. At the time of admission he showed drastic reduction in urine output, absence of hydronephrosis, normal functioning of the catheter, a tense and widely meteoric abdomen, the presence of air-fluid levels, normal kidneys, absence of free fluid in the abdomen. The CT showed a fluid collection of about 7 cm diameter between the bladder and rectum. The explorative laparotomy found a small fissuration of the posterior wall of the bladder. For his severe conditions, the patient died a few hours after surgery, in intensive care unit. Although it is a rare event, since 1980, 177 cases of spontaneous rupture of the bladder are reported in the literature. Their causes may be essentially divided into two groups: for increase of intravesical pressure; or for weakening of the bladder wall. In most cases, the spontaneous rupture of the bladder takes place in presence of a urothelial neoplasm or after radiation therapy of the pelvic organs. The etiology of spontaneous rupture of the bladder in our case does not relate to a bladder tumor or radiotherapy. It may have been caused by repeated episodes of acute retention of urine with extreme bladder distension up to 3 liters. It is not easy to think of a bladder perforation in patients presenting signs of peritonitis without a history of bladder cancer or pelvic radiotherapy. A CT with intravesical contrast medium could help the diagnostic orientation.

  13. Spontaneous intramural rupture and intramural haematoma of the oesophagus.

    1980-01-01

    Spontaneous intramural rupture or intramural haematoma of the oesophagus is a rare cause of acute pain in the chest and upper abdomen. Much less ominous than spontaneous complete rupture from which it must be distinguished, it seldom if ever necessitates operation. Five new cases are described and reviewed together with 15 collected from published reports. The dominant symptom of every case was severe and constant retrosternal or epigastric pain; concomitant dysphagia was mentioned in 11 cases. In seven the pain was preceded by or coincided with vomiting. The condition was related to other stresses in three and appeared to be truly spontaneous in 10. In approximately one-third of cases it started suddenly but more often it began as discomfort worsening rapidly. Fourteen patients vomited blood after experiencing pain but only four were given transfusions. In contradistinction to complete rupture, none had surgical emphysema and plain chest radiographs were unremarkable. All had abnormal gastrografin or barium swallows. Intramural haematomas with or without mucosal tears were seen in the 11 cases in which oesophagoscopy was performed. Fifteen patients made rapid and complete recoveries on conservative management. Of the four who did not respond satisfactorily, one had the oesophagus repaired, two had drainage of the mediastinum after failure to find the false lumen at thoracotomy, and one had only an abdominal exploration. The only death in the whole series occurred after a disastrous emergency exploration and subsequent total oesophagectomy. Images PMID:6973833

    To study the diagnosis, prognosis and management of spontaneous rupture of the esophagus. This is a retrospective study through the analysis of two cases with delayed diagnosis and subsequent treatment at the Track Surgery Service. LOCALE: The study was performed at the Thoracic Surgery Unit of the Hospital do Servidor Público Estadual Francisco Morato de Oliveira in the city of São Paulo. This is a specialized service. The two patients reported on had suffered spontaneous rupture of the esophagus. They were transferred to the Thoracic Surgery Unit because of the worsening of their condition in the previous institution which they had been admitted into. The two patients with esophagus pleural fistula received similar treatment, initially advocated by Kanashin in Russia and Hauer-Santos in the United States, which consists of washing the fistula and using continuous pleural aspiration. Although both patients had to spend a long period of time in hospital, their evolution was satisfactory with the treatment adopted, and the fistula closed. The authors conclude that the method of lavage of the mediastinum and continuous pleural aspiration, in patients who after spontaneous rupture of the esophagus developed a pleural esophagus fistula due to belated diagnosis, is an alternative and satisfactory therapy. Furthermore, in order to have the best outcome, an early diagnosis is recommended and thoracostomy as the surgical procedure, with primary suture.

    Spontaneous rupture of hepatocellular carcinoma (HCC) is a catastrophic surgical emergency with high mortality rates. The aim of this study is to determine the factors associated with the prognosis and to assess the outcome of different management strategies. A retrospective study of 34 consecutive patients with spontaneous rupture of HCC was conducted from January 1996 to January 2004. Clinical, biochemical and operative factors influencing 30-day mortality were analysed. In our study, 30-day mortality rate was 32% (n = 11). Presence of cirrhosis, Child's C status, shock on admission, higher blood transfusion requirement, raised alpha-fetoprotein, raised alkaline phosphatase, raised aspartate transaminase, and raised indocyanine green at 15 min were all associated with increased risk of 30-day mortality on univariate analysis (P < 0.05). On multivariate analysis, only shock on admission (P = 0.001) and higher blood transfusion requirement (P = 0.01) were significant independent factors affecting early mortality. Surgical intervention was associated with a better 30-day survival as compared with medical therapy or transarterial embolization. The median survival time of patients undergoing curative resection was significantly longer than that of patients who had surgery for haemostasis only (420 vs 205 days). The overall median survival was 161 days. Spontaneous rupture of HCC is a potentially salvageable complication of HCC. Poor prognosis is associated with poor liver reserve, advanced disease and severity of haemorrhage. Shock and blood transfusion requirement are the only independent factors affecting early mortality.

    Uterine rupture is a rare but potentially catastrophic complication of pregnancy that requires rapid diagnosis. Classically, its signs and symptoms combine pain, fetal heart rate (FHR) abnormalities, and vaginal bleeding. The purpose of this study is to identify these signs and symptoms as well as the immediate complications of complete and incomplete (partial) ruptures of the uterine wall, whether or not they follow a previous cesarean delivery. Retrospective study of case records from two university hospital maternity units, from 1987 to 2008. In a total of 97,028 births during the study period, we identified 52 uterine ruptures (0.05%): 25 complete and 27 partial. Most (89%) occurred in women with a previous cesarean delivery. In complete ruptures, FHR abnormalities were the most frequent sign (82%), while the complete triad of FHR abnormalities-pain-vaginal bleeding was present in only 9%. The signs and symptoms of partial ruptures were very different; these were asymptomatic in half the cases (48%). Neonatal mortality reached 13.6% among the complete ruptures; 27 and 40% of these newborns had pH<6.80 and pH<7.0, respectively. Among the incomplete ruptures, only 7.7% of the newborns had a pH<7.0 and there were no deaths. Although complete rupture of the uterus has a severe neonatal prognosis, the complete set of standard symptoms is present in less than 10% of cases. FHR abnormalities are by far the most frequent sign. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  17. Two Cases of Spontaneous Liver Rupture and Literature Review

    1996-01-01

    Spontaneous liver rupture is uncommon, difficult to diagnose and carries a universally high mortality. It has been well documented to occur as a complication of primary or secondary hepatic malignancy. Similarly, there are 28 cases of ruptured haemangiomata described in the world literature. It is also well described in severe pregnancy-induced hypertension and is said to carry a mortality of 18% for patients treated by packing and drainage of the haematoma and 75% for patients treated with liver resection. Two female patients aged 60 and 61 presented to our accident and emergency department. One had a history of hypertension only and the other a history of a bleeding diathesis from the lupus anticoagulant. Both presented with hypotension and abdominal pain and both were diagnosed by abdominal CT scan. One was treated with hepatic artery ligation and tamponade and the other with liver resection and correction of the coagulopathy. Neither had any evidence of a ruptured haemangioma or tumour at laparotomy or on histological examination, and both are alive and well. The conclusions to be drawn from this review and our own recent experience is that the treatment of choice for ruptured haemangiomata is liver resection and, for rupture during pregnancy, is tamponade with packs and evacuation of the haematoma. Hepatic arteriography and embolisation, if possible, is a useful adjunct. Correction ofany coagulopathy is essential. We can only speculate that the aetiology in our patients was uncontrolled hypertension in one and coagulopathy in the other. PMID:8809590

    Pyometra is the accumulation of pus in the uterine cavity, and spontaneous perforation of pyometra resulting in generalized diffuse peritonitis is extremely uncommon. We report a rare case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 66-year-old postmenopausal woman with diffuse abdominal pain and vomiting was admitted to our institution. She had a history of mixed connective-tissue disease and had been taking steroids for 20 years. Under a diagnosis of generalized peritonitis secondary to perforation of the gastrointestinal tract or uterus, supravaginal hysterectomy and bilateral salpingo-oophorectomy were performed. Unfortunately, wound dehiscence and infection occurred during the postoperative course, which were exacerbated by her immunocompromised state. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on the 36th postoperative day. Although correct diagnosis, early intervention, and proper treatment can reduce morbidity and mortality of spontaneous perforation of pyometra, if severe infection occurs, this disease can be life threatening for immunocompromised hosts.

    A 31-year-old nulliparous woman with severe diffuse uterine adenomyosis, which replaced nearly the whole uterine myometrium, visited our hospital due to severe dysmenorrhea, menorrhagia, and a desire to have a baby. The patient had a history of two spontaneous abortions. Laparotomic adenomyomectomy with transient occlusion of uterine arteries (TOUA) was performed safely and the patient tried in vitro fertilization and achieved a intrauterine twin pregnancy after recovery time of the operation. At 31+6 weeks of gestation, a male neonate baby weighing 1,620 g and a male neonate baby weighing 1,480 g were born by transverse lower segment cesarean delivery. There was no complication after the operation. The babies were discharged after receiving routine neonatal intensive care for neonatal respiratory distress syndrome. Adenomyomectomy with TOUA technique would be an option for conservative surgical treatment in patients with severe diffuse whole uterine adenomyosis. This is the first report of twin pregnancy after diffuse whole uterine adenomyomectomy with TOUA. PMID:27462599

    A 58-year-old man with advanced-stage pancreatic adenocarcinoma presented with fatigue and dyspnea. Examination revealed tachycardia (102 b/min) with mild tenderness in right upper quadrant. His hemoglobin (Hb) was 7.9 g/dL (10 days prior to presentation 12.2 g/dL), International normalized ratio (INR), platelet count was normal, and the stool guaiac test was negative. On admission, abdominal computed tomography (CT) scan showed hepatic metastatic lesion with a rupture and hemoperitoneum communicating to the subdiaphragmatic space. This rapid progression of anemia along with presenting symptoms and CT imaging were attributed to diagnosis of spontaneous rupture of liver metastasis from pancreatic adenocarcinoma. Patient received blood transfusion and hemoglobin was monitored in successive intervals. His general condition and anemia improved with conservative management and he was discharged in 3 days. Repeated CT after 4 months showed resolving hemoperitoneum and stable hemoglobin levels. The patient deceased 9 months after being diagnosed. A literature search revealed limited data regarding the incidence and management of spontaneous rupture of metastatic lesion secondary to pancreatic adenocarcinoma which has been managed conservatively and thus we are reporting our experience.

    A 48-year-old man was transferred to our emergency room because of sudden-onset epigastric pain and nausea. Abdominal contrast-enhanced computed tomography (CT) showed splenomegaly with splenic infarction and intra-abdominal bleeding, suggestive of splenic rupture. An emergent open splenectomy was performed. His spleen was markedly swollen and showed continuous bleeding due to a laceration. On histopathological examination, his spleen was filled with abnormal tumor cells. He was diagnosed as having mantle cell lymphoma based on the findings of immunohistochemical and cytogenetic analyses of the spleen. Mantle cell lymphoma cells were identified in the bone marrow and ileum, and he was determined to be in stageIVA by positron emission tomography (PET)-CT. He was administered rituximab combined with hyper-CVAD/MA chemotherapy (R-hyper-CVAD/MA regimen). After two courses of the R-hyper-CVAD/MA regimen, he achieved complete response, as confirmed by PET-CT. He received four courses in total of the R-hyper-CVAD/MA regimen, followed sequentially by high-dose chemotherapy and autologous peripheral blood stem cell transplantation (auto-PBSCT). He is currently alive and free of disease. This is the 10(th) report of a mantle cell lymphoma case with spontaneous splenic rupture. We herein review previous reports and emphasize the importance of awareness of hematological malignancies when encountering a case with spontaneous splenic rupture.

    To show the possibility of laparoscopic management of uterine rupture. Video with explanations. In the medical management with misoprostol for termination of pregnancy at any time the risk of uterine rupture may be possible. The risk is likely higher in women with a previous uterus surgery. In a systematic review of available studies, the risk of rupture was .28% among women with a prior cesarean delivery who were undergoing second-trimester misoprostol-induced abortion, meaning if 414 women with a history of cesarean delivery were given misoprostol for second-trimester abortion, 1 would experience uterine rupture. Uterine rupture has only been reported 3 times in first-trimester abortion and only once managed via laparoscopy: a missed abortion reported in 2005, a case of a ruptured unscarred uterus in a women undergoing medical abortion, and a case of a delayed miscarriage at 8 weeks' gestation after misoprostol managed by laparotomy and sharp curettage. Total laparoscopic management in a patient with uterine tear after misoprostol treatment. Early second-trimester medical abortions with misoprostol can cause uterine rupture. In hemodynamically stable cases, total laparoscopic management is possible approach. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

    Vascular Ehlers-Danlos Syndrome (VEDS) is a rare autosomal dominant collagen vascular disorder. Different from other Ehler-Danlos Syndrome subtypes, VEDS has poor prognosis due to severe fragility of connective tissues and association with life-threatening vascular and gastrointestinal complications. Spontaneous splenic rupture is a rare but hazardous complication related to this syndrome. To date, only 2 cases have been reported in the literature. Here we present another case of this uncommon complication, occurring in a 54-year-old woman in clinical follow-up for VEDS who presented with sudden onset of abdominal pain and hypotension.

    Spontaneous bladder rupture is rare. Presentation is non-specific and in absence of history of trauma, radiation, inflammatory conditions and other leading causes, there is considerable diagnostic delay. Absence of clear cut diagnostic signs leads to increased morbidity and mortality. In many patients, omentum seals perforation, giving diverticular appearance in Cystogram. The objective of this case report is to highlight important specific diagnostic points in history and radiology which will help in clear, early diagnosis and treatment causing immense benefit to the patient. We would also like to highlight a specific radiological point to distinguish true from pseudo-diverticulum.

    To estimate the time from the diagnosis of uterine rupture to delivery that would prevent adverse neonatal sequelae. Cases of uterine rupture from January 1, 2000, to December 31, 2009, were identified in nine hospitals in the Intermountain Health Care system and at the University of Utah. Maternal demographics, labor characteristics, and neonatal outcomes were obtained. Primary adverse outcome was abnormal umbilical artery pH level less than 7.0 or 5-minute Apgar score less than 7. Adverse secondary outcome included fetal or neonatal death and neonatal neurologic injury attributed to uterine rupture. Thirty-six cases of uterine rupture occurred during 11,195 trials of labor after cesarean delivery. Signs of uterine rupture were fetal (n=24), maternal (n=8), or a combination of maternal and fetal (n=3). In one case, uterine rupture was not suspected. Mean time to delivery from the onset of symptoms or signs for the primary adverse outcome group (n=13) was 23.3 (±10.8) minutes compared with 16.0 (±7.7) minutes for those without an adverse outcome (P=.02). No neonate delivered in fewer than 18 minutes had an umbilical pH level below 7.0. Three neonates delivered at more than 30 minutes met criteria for an adverse secondary outcome. The frequency of uterine rupture was 0.32% in patients attempting a trial of labor after cesarean delivery. Neonates delivered within 18 minutes after a suspected uterine rupture had normal umbilical pH levels or 5-minute Apgar scores greater than 7. Poor long-term outcome occurred in three neonates with a decision-to-delivery time longer than 30 minutes. II.

    Pregnancy in a rudimentary horn is a very rare condition. It is responsible for several complications. Prognosis is reserved because the natural evolution generally leads to a cataclysmic uterine rupture at the beginning of the second trimester. Classically, the treatment after foetal extraction consists of ablation of the rudimentary horn and associated fallopian tube. We report the obstetric outcome of a patient with history of rudimentary uterine horn rupture, the treatment of which was ablation of the rudimentary horn. PMID:21483504

    We describe a rare case of complete hydatidiform mole with twin live fetus (CHMTF) confirmed by histopathology, flow cytometry and polymerase chain reaction techniques. No malformations were observed, fetal karyotype was normal and β-human chorionic gonadotropin levels were high (>100,000 IU/ml). The patient was informed of the risks and decided to continue with the pregnancy, but at week 15, she had to undergo hysterectomy due to uterine rupture. She subsequently developed persistent trophoblastic disease (PTD) with pulmonary metastases that required treatment with polychemotherapy. Patients with CHMTF should be informed of all known risks, including the considerable risk of PTD, which is similar to or, even higher than that associated with a singleton complete mole. The risk does not appear to be increased by continuing the pregnancy. Because so few series have been published, there is a lack of evidence-based clinical management guidelines. To our knowledge, this is the first report of uterine rupture in CHMTF.

    Placental adhesive disorders involve the growth of placental tissue into or through the uterine wall. Among these disorders, placenta percreta is the rarest one. However, it may cause significant complications. This report aimed to report a neglected patient with placenta percreta who developed uterine rupture with life-threatening late postpartum intra-abdominal hemorrhage. On admission, the patient had acute abdomen with moderate abdominal distention and was subjected to emergency laparotomy. A full-thickness defect of the anterior uterine wall involving the hysterotomy site was seen. Placental tissues occupied both sides of the incision and posterior bladder wall was also invaded by placenta. Total abdominal hysterectomy with partial resection of the posterior bladder wall was performed. PMID:24392232

    Background. Imperforate hymen is usually treated with hymenotomy, and the management after its spontaneous rupture is not very well known. Case. In this paper, we present spontaneous rupture of the imperforate hymen in a 13-year-old adolescent girl with hematocolpometra just before a planned hymenotomy operation. The patient was managed conservatively with a satisfactory outcome. Conclusion. Hymenotomy may not be needed in cases with spontaneous rupture of the imperforate hymen if adequate opening for menstrual discharge is warranted. PMID:21637362

    A case is described of a 33-year old woman with systemic lupus erythematosus (SLE) in longterm treatment with corticosteroids who experienced spontaneous rupture of the left patellar tendon. A comparative study of 28 previously reported cases of SLE patients with spontaneous tendon rupture in weight bearing joints is performed. It is suggested that renal disease may be an etiological factor for spontaneous tendon rupture in patients with systemic lupus erythematosus.

    Mediastinal paraganglioma is a rare neurogenic tumor with a hypervascular feature. The spontaneous rupture of mediastinal paraganglioma is an unusual cause of massive hemothorax. Here we present a case of 39-year-old man with massive hemothorax due to the spontaneous rupture of a mediastinal paraganglioma. The man underwent successful resection of tumor and had an uneventful recovery. To our knowledge, this is the first reported case of spontaneous rupture of nonfunctioning mediastinal paraganglioma.

  15. The Energy Budget of Earthquake Rupture: a View From Spontaneous Rupture Modeling and Finite-Source Models

    NASA Astrophysics Data System (ADS)

    Mai, P.; Guatteri, M.

    2003-12-01

    It is a common and frustrating experience of many dynamic modelers to initiate spontaneous rupture calculations that subsequently abort before rupturing to the desired earthquake size [Nielsen and Olsen, 2000; Oglesby and Day, 2002]. Source parameters in such dynamic source models are strongly correlated, but stress drop is the main factor affecting the distribution of the other dynamic rupture parameters. Additionally, the position of the hypocenter exerts a strong influence on the dynamic properties of the earthquake, and certain hypocenter positions are not plausible as those would not lead to spontaneous rupture propagation. To further investigate this last statement, we analyze the energy budget during earthquake rupture using spontaneous dynamic rupture calculations and finite-source rupture models. In describing the energy budget during earthquake rupture, we follow Favreau and Archuleta [2003]. Each point on the fault contributes to the radiated seismic energy Ers = Eel - Efr - Erx, where Eel denotes the elasto-static energy and Efr the fracture energy. In this study we neglect for simplicity the relaxation work Erx spent during the stopping of the earthquake. A rupture can be characterized by locally negative seismic energy density values, but its integral over the fault plane must be positive. The fundamental condition for rupture growth is therefore that the integral of Ers on the rupture area remains always positive during rupture propagation. Based on a simple energy budget calculation, we focus on identifying those target slip/stress distribution in dynamic rupture modeling that for a given hypocenter location fail to rupture spontaneously. Additionally, we study the energy budget of finite-source rupture models by analyzing the integrated seismic energy for the inferred slip maps using also hypocenter positions other than the network location. These results indicate how rupture was promoted for the true hypocenter while randomized hypocenters may not

    Bilateral simultaneous ruptures are rare comprising less than 1% of all Achilles tendon ruptures. Risk factors for bilateral ruptures include chronic diseases and medications such as corticosteroids and fluoroquinolones. There is little in the literature on the long-term functional outcome of bilateral Achilles tendon ruptures. This article present a series of 3 cases of simultaneous and spontaneous bilateral Achilles tendon ruptures with a minimum of 5-year follow up suggesting a good functional outcome.

    To compare cardiotocographic abnormalities recorded during labour in women with prior caesarean delivery (CD) and complete uterine rupture with those recorded in controls with prior CD without uterine rupture. Women with complete uterine rupture during labour between 1997 and 2008 were identified in the Danish Medical Birth Registry (n = 181). Cases were validated by review of medical records and 53 cases with prior CD, trial of labour, available cardiotocogram (CTG) and complete uterine rupture were included and compared with 43 controls with prior CD, trial of labour and available CTG. The CTG tracings were assessed by 19 independent experts divided into groups of three different experts for each tracing. The assessors were blinded to group, outcome and clinical data. They analyzed occurrence of defined abnormalities and classified the traces as normal, suspicious, pathological or pre-terminal according to international guidelines (FIGO). A pathological CTG during the first stage of labour was present in 77% of cases and in 53% of the controls (OR 2.58 [CI: 0.96-6.94] P = 0.066). Fetal tachycardia was more frequent in cases with uterine rupture (OR 2.50 [CI: 1.0-6.26] P = 0.053). Significantly more cases showed more than 10 severe variable decelerations compared with controls (OR 22 [CI: 1.54-314.2] P = 0.022). Uterine tachysystole was not correlated with the presence of uterine rupture. A pathological cardiotocogram should lead to particular attention on threatening uterine rupture but cannot be considered a strong predictor as it is common in all women with trial of labour after caesarean delivery.

    Spontaneous splenic rupture, also referred to as atraumatic splenic rupture, is a rare but life-threatening emergency condition. Without timely diagnosis and treatment, the mortality rate of splenic rupture approaches 100%. The etiology of atraumatic splenic rupture varies; it is reportedly associated with neoplasms or splenic infection, but is rarely encountered in patients with both conditions. We herein report the case of a 58-year-old male patient with acute myeloid leukemia (AML) complicated by splenic tuberculosis (TB), who presented with spontaneous rupture of the spleen. Pathological examination of the resected spleen revealed multifocal granulomatosis with caseous necrosis. However, with timely diagnosis and surgical intervention, the patient recovered successfully and is currently on consolidation therapy. To the best of our knowledge, this is the first case of spontaneous splenic rupture in AML with splenic TB. The relevant literature on spontaneous splenic rupture was also reviewed and the potential etiology and treatment were discussed. PMID:28357096

    Uterine diverticula and rudimentary horns are rare forms of uterine anomalies that occur during embryogenesis. They can communicate with the endometrial cavity and may have the potential to develop pathology. This case report presents an obese, anovulatory adolescent with polycystic ovarian syndrome who was admitted with acute abdominal pain and found to have radiological findings that were concerning for a ruptured mass contiguous with the uterine cavity, which was likely a uterine horn or diverticulum. Further evaluation revealed simple hyperplasia without atypia on endometrial sampling, supporting the surgical resection and subsequent medical management of this young patient.

    Rupture of unscarred uterus during the second trimester is rare. There have been only 32 cases reported in the literature since 1968. A case of ruptured uterus in a grand multiparous woman is presented. To our knowledge, this might be the first reported case in the English literature of uterine rupture during second trimester termination of pregnancy using a prostaglandin E1 analogue (Misoprostol) and oxytocin.

    A 30-year-old, gravida 2, para 0 woman who had a history of a laparoscopic cornuostomy for a left interstitial pregnancy was admitted for a vaginal delivery due to labor pains at 40 weeks gestation. A prolonged placental delivery, persistent abdominal pain, and hemorrhagic shock were noted after the delivery of the infant. An emergency laparotomy was carried out, and the diagnosis of a uterine rupture at the scar of a prior cornuostomy was confirmed. The entire placenta extruded through the rupture wound into the abdominal cavity. A Medline computer search revealed that a similar case of a uterine rupture after full-term vaginal delivery has yet to be reported. In order to prevent a uterine rupture, we suggest that a planned cesarean delivery, before the onset of labor in a subsequent pregnancy, may be safer for a patient with a scarred uterus from a prior cornuostomy for an interstitial pregnancy.

    Spontaneous rupture of the urinary bladder is an uncommon occurrence. A 36-year-old man had complaints of pain and progressive distension of abdomen and anuria for 2 days. His abdomen was tense, tender and distended with free fluid. Blood urea was 340 mg% and ascitic fluid urea was 337 mg%. An USG showed massive ascitis, a large vesical calculus and a left renal calculus. The urinary bladder could not be catheterized. Patient underwent hemodialysis and placement of abdominal drains. About 2 l of yellow turbid fluid was drained. Cystolithotomy showed a 6 cm size impacted calculus with a rent in the dome of the bladder, which was repaired. Subsequently patient underwent percutaneous nephrolithotrypsy for left staghorn renal calculus and nephrectomy for right non-functioning kidney.

    Spontaneous bleeding of thymoma is a very rare event. We report the case of a 73-year-old woman who was referred to our hospital for acute onset of chest pain followed by shock. Chest computed tomographic scanning showed a huge mediastinal tumor with abundant left pleural effusion and contralateral shift of the mediastinum. Emergency surgical treatment was carried out through a clamshell incision. At the opening of the left pleura 1,600 mL of fresh blood was found, originating from a rupture of the tumor's capsular veins. The lesion was completely resected, en-bloc with a wide pericardial excision. The postoperative course was uneventful. The pathology report classified the lesion as thymoma AB.

    Systemic lupus erythaematosus (SLE) is known to involve the reticuloendothelial system, but spontaneous splenic rupture (SSR) in the context of the disease is a very rare complication. We observed a 61-year-old woman with an unremarkable previous medical history who presented with SSR and underwent an emergency splenectomy. The histopathological analysis of the specimen revealed signs of vasculitis. On review of symptoms with the patient, a history of oligoarthralgia, photosensitivity, xerostomia and Raynaud phenomenon was elicited. Laboratory investigations revealed lymphopaenia, mild proteinuria and positive antinuclear and anti-dsDNA antibodies. The patient was started on hydroxychloroquine and the disease has since remained silent. This article addresses the rare association between SLE and SSR. 2015 BMJ Publishing Group Ltd.

    Peritonitis secondary to spontaneous rupture/perforation of the gall bladder is a rare condition overall and is even less common in the forensic population. We report the case of a middle-aged man who died from generalized peritonitis from gall bladder perforation due to acute acalculous cholecystitis. This condition usually occurs in critical patients with systemic illness, and although the exact pathogenesis remains unclear, the development of acalculous cholecystitis appears to be multifactorial. Antemortem diagnosis is reliant upon clinical presentation, laboratory data, and radiologic studies. Surgery and appropriate antibiotics are mainstays of treatment; however, there is an emerging role for minimally invasive procedures. Histopathologic features show significant overlap with the calculous type. Although increasing numbers of acalculous cholecystitis have been diagnosed in the critically ill, the fatal presentation of a perforated gall bladder following an undiagnosed case of acute acalculous cholecystitis is unusual in a nonhospitalized and ambulatory man. © 2014 American Academy of Forensic Sciences.

    Spontaneous splenic artery aneurysm (SAA) is a rare but a life-threatening condition. Thus, early diagnoses may increase the chance of survival. A 52-year-old female patient was admitted to the emergency department with a pain that starts from the chest and epigastric region and radiates to back and left arm. The patient prediagnosed as having acute myocardial infarct and was under observation when acute abdomen and hemorrhagic shock developed. After further investigation, the patient was diagnosed as having SAA and has undergone a successful surgery. The patient was fully cured and discharged from the hospital on the seventh postoperative day. The patient originally presented with SAA, although she was primarily observed in the emergency department with acute myocardial infarct diagnosis because of similar symptoms and clinical findings to cardiovascular diseases. When changes in the clinical picture occurred, the patient was reevaluated and had undergone an operation because of SAA rupture. Therefore, physicians should take into consideration of aneurysm rupture in the differential diagnosis of the cardiovascular conditions; otherwise, the patient may lose his/her life.

  8. Galerkin boundary integral equation method for spontaneous rupture propagation problems

    2007-12-01

    We develop a Galerkin finite element boundary integral equation method (GaBIEM) for spontaneous rupture propagation problems for a planar fault embedded in a homogeneous full 2D space. A simple 2D anti plane rupture propagation problem, with a slip-weakening friction law, is simulated by the GaBIEM. This method allows one to separate explicitly the kernel into singular static and time-dependent parts, and a nonsingular dynamic component. The simulated results throw light into the performance of the GaBIEM and highlight differences with respect to that of the traditional, collocation, boundary integral equation method (BIEM). The rate of convergence of the GaBIEM, as measured from a root mean square (RMS) analysis of the difference of approximate solutions corresponding to increasingly finer element sizes is of a higher order than that of the BIEM. There is no restriction on the CFL stability number since an implicit, unconditionally stable method is used for the time integration. The error of the approximation increases with the time step, as expected, and it can remain below that of the BIEM.

    Endometrial ablation offers symptomatic relief for menorrhagia. Pregnancy after ablation is rare but is often complicated due to pregnancy loss, growth restriction, preterm premature rupture of membranes, preterm delivery, and morbidly adherent placentation, a dangerous complication that can result in hemorrhage, intensive care unit admission, and cesarean hysterectomy. We report a case of pregnancy conceived contemporaneously with endometrial ablation and tubal occlusion. Diagnosis of pregnancy was delayed due to low suspicion. Complications included cervical implantation and placenta percreta, necessitating hysterectomy with the fetus in situ. Intraoperatively, incomplete uterine rupture was noted. Abnormal neovascularization, fibrous adhesions, and anatomical distortion necessitated a complex surgical approach. Women undergoing endometrial ablation must be thoroughly counseled about the serious risks of postablation pregnancy, the need for contraception, and the risk of sterilization failure. Pregnancy should remain in the differential diagnosis for women of reproductive age, regardless of tubal occlusion. Cases of placenta percreta should be referred early to centers of excellence with multidisciplinary teams. PMID:28050333

    Background Uterine rupture is a common complication in women attempting their first virginal birth after caesarean section (VBAC) but the risk diminishes with subsequent VBACs. It occurs in rates of 0.5-9% and is influenced by various factors. Case presentation A unique case of uterine rupture in a Kenyan woman of African descent during a repeat VBAC complicated by shoulder dystocia was discovered during the 4th stage of labour when omentum was noted protruding through the vagina. She had delivered 4 years earlier by caesarean section. Conclusion It is not common to experience uterine rupture among women attempting repeat VBAC. When it occurs, it may not always follow the known pattern intra-partum and is often associated with poor foetal outcome. PMID:23521920

    2016-01-01

    Objectives: It is widely believed that ACL tears are incapable of healing. However, there are anecdotal experiences of the healed ACL and sporadic case reports and series documenting either clinical or radiographic evidence of healed ACL tears. A truly healed ACL would demonstrate a clinically stable knee on Lachman and pivot shift testing, normal return to function and MRI and/or arthroscopic documentation of a continuous ligament. This is in contrast to “copers” who have an ACL deficient knee but lack instability either because of good neuromuscular control or non-participation in activities which are heavily ACL dependent. In this prospective series we report on the presentation and 5 year follow-up of patients with both clinical and radiographically healed ACLs. Methods: 19 patients who presented between July 2007 and April 2010 within 6 weeks of injury with clinical laxity and MRI confirmed ACL rupture. Patients subsequently demonstrated clinical knee stability at 8-12 weeks after pre-habilitation to obtain a pain free mobile joint. Prospective data was collected on these patients with MRI at 12 months, IKDC clinical and subjective scores, KT1000 instrumental laxity testing and Lysholm knee score at 12, 24 and 60 months. Results: At one year follow-up MRI 18/19 patients demonstrated a healed ACL with normal signal, normal trajectory and continuity of fibres. Remainder 1 patient demonstrated bridging of ACL tear with scar tissue and abnormal trajectory of fibers. 5 of 19 patients re-ruptured within 5 years of follow-up. At 5 years follow-up, intact healed ACL patients had a mean IKDC score of 88, mean Lysholm score of 92 and mean KT1000 score of 1.7 mm. 100% reported regular participation in strenuous sport. Conclusion: Although rare, spontaneous healing of the ACL is possible. The mechanism by which this occurs in unknown. It is recommended that reassessment of knee stability should be performed in the non-acute phase after an appropriate prehabilitation

    The authors aimed to determine and compare the uterine artery pulsatility index (PI) between spontaneous and IVF twins in the second trimester. All medical records of twin pregnancies, whose fetal screening was done between May 1999 and December 2013, were evaluated retrospectively. All twin pregnancies without detected/suspicious anatomical or genetic fetal anomalies, systemic diseases, biochemical abnormalities, and familial genetic diseases were included in the data analyses. Fetuses with no information on spontaneous or IVF conception and fetuses with undetermined uterine artery impedance of second trimester were excluded from the data analyses. A total of 151 twin pregnancies were evaluated in the analyses. The percentages of spontaneous and IVF twins were 24.5% and 75.5%, respectively. Mean gestational age was 19.95 ± 2.25 weeks in IVF twin group and 20.10 ± 2.19 weeks in spontaneous twin group. The difference of the gestational age between groups was not statistically significant. Mean uterine artery impedance was found as 0.78 ± 0.22 in IVF twins and 0.96 ± 0.31 in spontaneous twins respectively). Mean values were significantly lower in the IVF twins (p = 0.09). The uterine artery PI in the second trimester is significantly lower in IVF twins compared to the spontaneous twins.

    Spontaneous flexor tendon rupture is a rare condition and the aetiology is not clear. We report 12 elderly Korean farmers with spontaneous flexor tendon ruptures. We found the rupture in the dominant hand in ten patients. A rupture in the little finger was found in all 12 patients (seven with both flexor tendons ruptured and five with only the profundus ruptured), in the ring finger in four patients (the profundus ruptured in all and both flexor tendons in two patients), and in the middle finger a partial rupture of the profundus in one patient. The tendons were ruptured close to the hook of the hamate. Repetitive friction between the flexor tendons and the hamate hook may cause the ruptures. The hamate hook was excised and the ruptured profundus tendons were reconstructed with tendon transfers with quite favourable functional recovery at follow-up of 1 to 2 years. The ruptured superficialis tendons were not reconstructed. Level of Evidence IV.

    2012-01-01

    Introduction Anisakidosis, human infection with nematodes of the family Anisakidae, is caused most commonly by Anisakis simplex. Acquired by the consumption of raw or undercooked marine fish or squid, anisakidosis occurs where such dietary customs are practiced, including Japan, the coastal regions of Europe and the United States. Rupture of the spleen is a relatively common complication of trauma and many systemic disorders affecting the reticuloendothelial system, including infections and neoplasias. A rare subtype of rupture occurring spontaneously and arising from a normal spleen has been recognized as a distinct clinicopathologic entity. Herein we discuss the case of a woman who presented to our institution with appendicitis secondary to Anisakis and spontaneous spleen rupture. Case presentation We report the case of a 53-year-old Caucasian woman who presented with hemorrhagic shock and abdominal pain and was subsequently found to have spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. She underwent open surgical resection of the splenic rupture and the appendicitis without any significant postoperative complications. Histopathologic examination revealed appendicitis secondary to Anisakis simplex and splenic rupture of undetermined etiology. Conclusions To the best of our knowledge, this report is the first of a woman with the diagnosis of spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. Digestive anisakiasis may present as an acute abdomen. Emergency physicians should know and consider this diagnosis in patients with ileitis or colitis, especially if an antecedent of raw or undercooked fish ingestion is present. Spontaneous rupture of the spleen is an extremely rare event. Increased awareness of this condition will enhance early diagnosis and effective treatment. Further research is required to identify the possible risk factors associated with spontaneous rupture of the spleen. PMID:22524971

    Splenic rupture in neonates is a rare event, usually occurring in the setting of underlying predisposing conditions. Here, we present the case of a term neonate who presented with worsening anemia in the setting of known hemolytic disease during the newborn period and was later found to have a spontaneous splenic rupture. He was subsequently diagnosed with severe hemophilia A, and was managed medically with recombinant factor VIII replacement therapy without any surgical intervention. This is the first reported case of a neonate who had spontaneous splenic rupture and severe hemophilia A, and underwent successful medical treatment without any surgical intervention.

    Background Spontaneous kidney rupture could develop in the course of posterior urethral valve (PUV), the most common cause of outflow urinary tract obstruction in male infants. However, urinary extravasation is a rare complication among this group of children. Case Presentation Our case report presents diagnostic difficulties connected with spontaneous kidney rupture due to PUV in a 6 week-old infant. Due to not equivocal images, thundery course of disease and rapid deterioration in the infant's condition, the patient required an urgent laparatomy. Conclusion This case showed that the investigation of renal abnormalities during early neonatal period, is very important specifically in PUV that can lead to kidney rupture. PMID:23795264

    1997-01-01

    A 32 year old woman, at the 23rd week + 3 days gestational age, was admitted to our institute for a therapeutic abortion decided because of an ultrasonographic diagnosis of anencephaly. This woman had already had a cesarean section caused by acute fetal stress during labor in 1992. We decided for a labor induction with prostaglandin analogues: we used gemeprost vaginal tablets and after injectable sulproste. During this treatment we observed increasing abdominal pain, slight genital haemorrhage, vanishing HFR, an elevated reduction of haemoglobin (7 g): so, we thought of a uterine rupture. During the intervention, we observed a conspicuous haemoperitonei caused by a complete yielding of the old hysterotomic suture at the cervix border; the placenta and its adnexals get out from the uterine breach and the fetus fluctuated in the abdominal cavity, also enclosed in his unruptured amniotic fluid. Post-intervention course was satisfactory and we discharged the patient during the 7th admission day. Our personal experience shows the importance of a careful monitoring of maternal and fetal conditions during labor induction, particularly in those cases in which a woman was already submitted to a hysterotomy, and especially when the use of different types of prostaglandin drugs may be necessary.

    Atraumatic splenic rupture is a rare event that has been associated with several infectious disease processes. In the active duty military population, potential exposure to these pathogens is significant. Here we discuss the case of an active duty Marine with spontaneous splenic rupture upon return from a six-month deployment in Iraq. A previously healthy 30-year-old Caucasian male active duty Marine presented with abdominal pain, fever and diarrhea after deployment to Iraq in support of Operation Iraqi Freedom. Based on clinical and radiographic evidence, a diagnosis of spontaneous splenic rupture was ultimately suspected. After exploratory laparotomy with confirmation of rupture, splenectomy was performed, and the patient made a full, uneventful recovery. Histopathologic examination revealed mild splenomegaly with a ruptured capsule of undetermined cause. Spontaneous splenic rupture is a rare event that may lead to life-threatening hemorrhage if not diagnosed and treated quickly. Although the cause of this patient's case was unknown, atraumatic splenic rupture has been associated with a variety of infectious diseases and demonstrates some risks the active duty military population may face while on deployment. Having an awareness of these pathogens and their role in splenic rupture, clinicians caring for military personnel must be prepared to recognize and treat this potentially fatal complication.

    Tendo-Achilles (TA) rupture is the most commonly ruptured tendon in the lower limb despite being one of the toughest tendons. Typically, it occurs unilaterally in middle-aged individuals who participate in strenuous activity. Spontaneous ruptures without any risk factors predisposing the patient is uncommon and for it to occur bilaterally is very rare. To raise awareness of the potential for TA ruptures to occur bilaterally and thus the importance of assessing the TA contralateral to a seemingly unilateral rupture. This is particularly the case in patients with risk factors, which are reviewed in this report. A summary of the main treatment options is also described. We report a case of spontaneous, bilateral TA rupture in a 40-year-old man with no identifiable risk factors. It occurred following a heavy impact during a sports activity and although painful, was able to mobilize slowly. After a clinical examination confirmed the diagnosis, the patient underwent early bilateral surgical repair and subsequently embarked on a comprehensive rehabilitation program with a good functional outcome at follow-up. His return to premorbid work and social life was uneventful. Bilateral TA ruptures are rare but increased awareness would help avoid a tear or rupture of the contralateral side being missed. All patients presenting clinically with any TA rupture should have risk factors reviewed. Surgical repair must be accompanied by a comprehensive rehabilitation program for adequate recovery and return of function.

    Uterine rupture is an uncommon complication following termination of pregnancy and is usually accompanied by severe lower abdominal pain and shock caused by intra-abdominal hemorrhage. Laparotomy should be carried out promptly in order to repair the uterus or even to resect the uterus. Here we present a case of uterine rupture of a scarred uterus, which occurred during a second-trimester induced abortion. The patient was successfully treated by laparoscopy with the help of laparoscopic ultrasound. This case suggests an alternative, effective approach to the diagnosis and treatment of uterine rupture. © 2015 Japan Society of Obstetrics and Gynecology.

    Craniopharyngioma is a relatively benign intracranial tumour that involves sellar and supra-sellar regions. Spontaneous rupture of craniopharyngioma into the sub-arachnoid space or into the ventricles is a rare phenomenon and few cases are reported in literature. We hereby report a case of sellar-suprasellar craniopharyngioma with focal intra-parenchymal rupture into brain causing aggravation of headache in a 12-year-old female child. This complication is a relatively rare phenomenon, which requires attention for early intervention. This was managed by trans-nasal endoscopic trans-sphenoidal surgery. Usually rupture of craniopharyngioma causes chemical meningitis or it can be asymptomatic. Sometimes rupture can cause complete resolution of cyst and symptoms. In the present case, there was only focal rupture and it was into brain parenchyma causing brain oedema with aggravation of headache. Magnetic Resonance Imaging (MRI) in intra-parenchymal rupture of craniopharyngioma has been emphasized in this case report.

    Spontaneous perforation of the uterus is rare, its incidence being about 0.01% − 0.05%. We report a rare case of diffuse peritonitis caused by spontaneously perforated pyometra. A 63-year-old woman with severe abdominal pain was admitted to our hospital. Laparotomy was performed because of the suspicion of gastrointestinal perforation with generalized peritonitis. At laparotomy, about 900 mL of pus was found in the peritoneal cavity. There were no abnormal findings in the alimentary tract, liver, or gallbladder. A total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Pathological investigation of the surgical specimen revealed endometritis and myometritis of the uterus; but there was no evidence of malignancy, and the cervical canal was patent. Although spontaneously perforated pyometra is rare, a perforated pyometra should therefore also be considered when elderly women present with acute abdominal pain. PMID:17485806

    Objectives We aimed to assess the prevalence of uterine rupture in Belgium and to evaluate risk factors, management and outcomes for mother and child. Design Nationwide population-based prospective cohort study. Setting Emergency obstetric care. Participation of 97% of maternity units covering 98.6% of the deliveries in Belgium. Participants All women with uterine rupture in Belgium between January 2012 and December 2013. 8 women were excluded because data collection forms were not returned. Results Data on 90 cases of confirmed uterine rupture were obtained, of which 73 had a previous Caesarean section (CS), representing an estimated prevalence of 3.6 (95% CI 2.9 to 4.4) per 10 000 deliveries overall and of 27 (95% CI 21 to 33) and 0.7 (95% CI 0.4 to 1.2) per 10 000 deliveries in women with and without previous CS, respectively. Rupture occurred during trial of labour after caesarean section (TOLAC) in 57 women (81.4%, 95% CI 68% to 88%), with a high rate of augmented (38.5%) and induced (29.8%) labour. All patients who underwent induction of labour had an unfavourable cervix at start of induction (Bishop Score ≤7 in 100%). Other uterine surgery was reported in the history of 22 cases (24%, 95% CI 17% to 34%), including 1 case of myomectomy, 3 cases of salpingectomy and 2 cases of hysteroscopic resection of a uterine septum. 14 cases ruptured in the absence of labour (15.6%, 95% CI 9.5% to 24.7%). No mothers died; 8 required hysterectomy (8.9%, 95% CI 4.6% to 16.6%). There were 10 perinatal deaths (perinatal mortality rate 117/1000 births, 95% CI 60 to 203) and perinatal asphyxia was observed in 29 infants (34.5%, 95% CI 25.2% to 45.1%). Conclusions The prevalence of uterine rupture in Belgium is similar to that in other Western countries. There is scope for improvement through the implementation of nationally adopted guidelines on TOLAC, to prevent use of unsafe procedures, and thereby reduce avoidable morbidity and mortality.

    Polyarteritis nodosa (PAN) is a vasculitis, which often involves small and medium sized visceral arteries. This condition may result in multifocal aneurismal formation and end-organ damage. Uncommonly, PAN may present with rupture of hepatic artery aneurysms. Here, we report a rare case of a ruptured intrahepatic aneurysm associated with PAN. A 79-year-old woman presenting with abdominal pain had CT scan of the abdomen, which revealed hematoma in the right hepatic lobe. Visceral angiogram confirmed pseudo-aneurysm of a right hepatic arterial branch, and this was managed with endovascular coil embolization. The diagnosis of PAN was made and corticosteroid therapy was initiated. We also performed a literature review to define this condition's demographics, clinical presentations, and appropriate management. The review revealed 17 published cases of ruptured PAN-related intrahepatic aneurysms. We conclude that unexplained findings of visceral arterial aneurysms should prompt investigations for vasculitis as the etiology.

    A 62-year-old man presented to the emergency department with an episode of syncope after 2-3 weeks of diffuse abdominal pain, now complaining of a severe increase in pain concurrent with >24 hours of no urine output. His workup showed an idiopathic extraperitoneal rupture of the bladder on computed tomography, which was handled conservatively with Foley insertion. Repeated follow-up and imaging showed no resolution or etiology over 2 months. The patient underwent exploratory laparotomy that showed an elongated appendix with a chronic tip appendicitis that had induced bladder rupture by chronic inflammatory changes. After repair, the patient had no further complaints.

    Spontaneous rupture of the urinary excretory system is a rare condition. It is mainly associated with obstruction of the excretory system and is usually unilateral. We report a 58 years old male who, during the performance of a computed tomography of the urinary system, felt an intense lumbar pain. A bilateral rupture at the level of the fornix was found. The patient had an uneventful evolution thereafter. Fifteen days later a new computed tomography showed indemnity of the urinary excretory system.

    Many complications have been reported after ear surgery to treat chronic inflammation. These complications include facial nerve paralysis, perichondritis, injury of the dura or of the sigmoid sinus, cyst formation or mucocele in the healed mastoid cavity, and the recurrence of cholesteatoma, granulation tissue, or otorrhea. It might be believed that there could be no relation between ear surgery and spontaneous aneurysmal rupture, and only one other case of spontaneous aneurysmal rupture after ear surgery under general anesthesia has been previously reported in Korea. However, recently, the authors encountered a case of delayed spontaneous aneurysmal rupture 3 weeks after surgery. No problem was experienced during the operation, and it is suspected that an unidentified pre-existing aneurysm was responsible for the intracerebral hemorrhage. PMID:24653877

    The present article was designed to report the results of the analysis of the cases of traumatic and spontaneous ruptures of the organs affected by the tumours based on the original observations and the literature data. It is shown that the probability of the tumour rupture depends on its histological type, localization, the size, and the distance from the capsule of the affected organ, the degree of involvement of the major blood vessels, the severity of the necrotic changes, the presence of cysts in the neoplasm, and the regimens of radio- and chemotherapy. Moreover, the rupture can be facilitated by anticoagulation therapy, intake or oral contraceptives, pregnancy, concomitant diseases, alcoholic intoxication, splenomegaly, and hypocoagulation resulting from dissemination of the neoplastic process or the metastatic lesions of the liver. Even a minimal injury to the skin can provoke the tumour rupture associated with the fatal hemorrhage. A delayed rupture within a few hours or days is possible.

    Background: The etiology of spontaneous rupture of the extensor pollicis longus tendon includes systemic or local steroid injections, wrist fracture, tenosynovitis, synovitis, rheumatoid arthritis, and repetitive wrist motions. Case Report: We encountered a case of extensor pollicis longus tendon rupture with an unusual etiology, cow milking. In this case, transfer of the extensor indicis proprius tendon was performed successfully. At 1 year after surgery, extension of the thumb was sufficient. Conclusion: It appears that patients with occupations involving repetitive motions are at a high risk of closed tendon ruptures. PMID:25207178

    Thoracic duct cysts in the mediastinum are extremely rare; they can give rise to chylothorax when they spontaneously rupture or after they are operated on. We present the case of an adult woman with a thoracic duct cyst in the mediastinum and chylothorax from its spontaneous rupture; to our knowledge, this phenomenon has not been specifically reported before. We describe the clinical and radiological findings, the therapeutic management, and the pathology findings, reviewing the literature for this entity. Copyright © 2016 SERAM.

    OBJECTIVE To assess the associations between maternal obesity, uterine contraction frequency, and spontaneous preterm birth in at-risk women. METHODS In a secondary analysis, we analyzed data from 253 at-risk women (prior spontaneous preterm birth, vaginal bleeding) enrolled in a multi-center observational study of home uterine activity monitoring at 11 centers. All women wore a uterine activity monitor twice daily from 22 through 34 weeks of gestation. Mean and maximal contractions/hour at 22-24, 25-26, 27-28, 29-30, 31-32, and at or after 33 weeks of gestation were compared between overweight/obese women (a BMI at 22-24 weeks greater than 25 kg/m2) and normal/underweight women (a BMI of at least 25 kg/m2) at each gestational age interval. Multivariable analysis evaluated the influences of BMI, contractions, fetal fibronectin and transvaginal cervical length on spontaneous preterm birth before 35 weeks. RESULTS Obese/overweight women (n=156) were significantly less likely to experience spontaneous preterm birth before 35 weeks (8.3 vs 21.7%, p<0.01). For each gestational age interval before 32 weeks, obese/overweight women had fewer mean contractions/hour (P<0.01 for each) and maximal contractions/hour (p<0.01 for each) than normal/underweight women, although their mean cervical lengths (34.3 vs 33.1 mm, p=0.25), and fetal fibronectin levels (7.1% vs. 7.2% ≥50 ng/mL, p=0.97) were similar at study enrollment. Obese/overweight status was associated with a lower risk of spontaneous preterm birth before 35 weeks after controlling for contraction frequency and other factors evaluated at 22-24 and 31-32 weeks, but not at later time periods. CONCLUSION Obese/overweight women at risk for spontaneous preterm birth exhibit less uterine activity and less frequent spontaneous preterm birth before 35 weeks of gestation than normal/underweight women.

Hemodynamic instability with abdominal pain and free fluid in the abdomen prompted blood transfusion and laparotomy. There were about 1000 cc blood and clots in the abdomen at laparotomy. There was a longitudinal rupture from fundus up to cervix at the left side of the uterus. Tearing was in full thickness from serosa to endometrium. Scar of previous cesarean was transvers and not associated with this tearing. There was not any myomectomy scar.

    A 52-year-old man was admitted to our hospital with a spontaneous esophageal rupture (Boerhaave syndrome) and was successfully treated. Eight years after the first incident, he was readmitted with a recurrent rupture. Recurrence of Boerhaave syndrome is extremely rare, with only 7 cases reported in the English literature. During treatment, the patient was also diagnosed with antiphospholipid syndrome (APS). Although APS is known to cause a variety of symptoms due to vascular thrombosis, recurrence of Boerhaave syndrome, coincident with APS, has never been reported. The pathogenesis of Boerhaave syndrome has not been clearly determined. This report serves to increase awareness of the risk of APS, which results in an increased risk of spontaneous rupture of the esophagus.

    Most renal neoplasms in adults are epithelial in origin and mesenchymal tumors are rarely encountered. Vascular tumors and tumor-like lesions account for a very small subset. Hemangioma of the kidney is a rarely seen benign vascular neoplasm that probably arises from angioblastic cells. Its general sign is macroscopic hematuria with or without pain. Preoperative diagnosis is difficult or impossible. Previously, spontaneous rupture of the kidney caused by renal hemangioma was not reported in the English literature. In this study, two cases with a history of nephrogenic hypertension who presented with spontaneous renal rupture are presented. There wasn’t any trauma history in the background of our patients. A long-standing nephrogenic hypertension was present in both patients. Patients underwent radical nephrectomy due to rupture of the renal tumor. In histopathological examination, capillary hemangioma was detected in the renal medulla in both cases. Patients didn’t need antihypertensive therapy during the postoperative period. PMID:26623154

    Spontaneous rupture of the spleen is a rare complication of hematological malignancies, occurring most commonly in patients with acute leukemia, but it has been documented in chronic leukemias and also in lymphomas. We report two patients with histologically and immunohistochemically confirmed mantle cell lymphoma (MCL) who experienced a spontaneous splenic rupture. An 80-year-old woman and a 51-year-old man had a blastoid variant of MCL and responded poorly to conventional treatment. Both patients recovered after splenectomy. The woman died of progressive lymphoma 2 months later. An allogeneic bone marrow transplantation was performed in the man with a good initial result, but an aggressive relapse was seen only 6 months later and he died of progressive lymphoma. In view of our data, we suggest special caution when MCL is complicated by rapid progression and severe splenomegaly. Although it is a rare phenomenon, the risk of splenic rupture should be kept in mind.

    A spontaneous rupture of the extensor pollicis longus (EPL) tendon is associated with rheumatoid arthritis, fractures of the wrist, systemic or local steroids and repetitive, and excessive abnormal motion of the wrist joint. The authors encountered a case of a spontaneous rupture of the EPL tendon. The patient had no predisposing factors including trauma or steroid injection. Although the patient had a positive rheumatoid factor, he did not demonstrate other clinical or radiological findings of rheumatoid arthritis. During surgery, the EPL tendon was found to be ruptured at the extensor retinaculum (third compartment). Reconstruction of the extensor tendon using the palmaris longus tendon was performed. At the 18-month follow-up, the patient showed satisfactory extension of the thumb and 40° extension and flexion at the wrist. PMID:21629480

  3. Numerical simulation of spontaneous rupture processes on twonon-coplanar faults: the effect of geometry on fault interaction

    Kase, Yuko; Kuge, Keiko

    1998-12-01

    Analyses of earthquake sources have revealed that the earthquake rupture process is complex and that the rupture does not occur on a single plane. Earthquake faults are often composed of several subfaults, and rupture propagation tends to decelerate or terminate at places where the fault strike changes. These observations imply that fault geometry, including fault steps and fault strike change, plays an important role in earthquake rupture complexity. In this paper, we calculate the spontaneous rupture processes of two non-coplanar faults in 2-D in-plane problems, attempting to clarify the effect of fault geometry. We consider two simple models-models in which two faults are either parallel or perpendicular to each other. We calculate spontaneous rupture propagation on the faults by a finite difference method, and we then compare the results. In our simulations, rupture initially grows on the main fault, and stress perturbation from the main rupture then triggers rupture on the secondary fault. Propagation of the main-fault rupture controls a spatio-temporal pattern of stress difference in the uniform elastic medium, which determines the rupture process of the secondary fault. The rupture propagation and termination of the secondary fault are significantly different between the two models. The difference is obvious when rupture of the main fault is arrested and the secondary fault is located near the arrested end of the main fault. When the secondary fault is parallel to the main fault, rupture can propagate ahead on the secondary fault. However, when the secondary fault is perpendicular to the main fault, rupture is either not triggered on the secondary fault, or soon terminates if triggered. This variation of the rupture process implies that fault interaction, depending on geometry, can explain the termination and change of rupture at places where the fault strike varies. This shows the importance of the fault geometry in studying spontaneous dynamic rupture

    Abstract Corticosteroid injections for hand tendinitis can lead to a rare significant complication of tendon spontaneous rupture. However, only sporadic cases were reported in the literature before. This study was designed to gauge the clinical effect of tendon repair in patients of tendon spontaneous rupture after corticosteroid injection and analyze our experience. This was a retrospective observational study of 13 patients (8 women and 5 men) operated between July 2011 and December 2015 for tendon spontaneous rupture after corticosteroid injection. Demographic data, clinical features, imaging data, and surgical treatments were carefully reviewed. The average age was 52.308 ± 15.381 years (range 29–71). The average injection times were 2.538 ± 1.664 times (range 1–6). The average rupture time (after last injection) was 10.923 ± 9.500 weeks (range 3–32). Nine patients were treated by tendon suture (69% of cases), and 4 patients were treated by tendon grafting (31% of cases). All patients received follow-up in our outpatient clinic. The sites of the tendon rupture (15 tendons of 13 patients had involved) include extensor pollicis longus (6 tendons, 40% of cases), extensor digiti quinti and extensor digiti minimi (4 tendons, 27% of cases), ring finger of extensor digitorum communis (3 tendons, 20% of cases), and middle finger of extensor digitorum communis (2 tendons, 13% of cases). Two patients who had tendon adhesion (15% of cases) were treated by tendon release. One patient who had tendon rerupture (8% of cases) was treated by tendon grafting. No patient had complications of infections, vascular, or nerve injury. Tendon spontaneous rupture is a serious complication after corticosteroid injection for tendinitis. Rigid standard of corticosteroid injection is very important. Magnetic resonance imaging was contributory to preoperative assess tendon defect and can be used to monitor healing quality of tendons during the follow-up. PMID:27741145

    Wound closure by 1 row of interupted sutures provides optimal healing conditions. As a result scar tissue formation is cut down. This general surgical principle is valid in stitching an uterotomy as well. Increasing frequency of cesarian section could end up in a rising number of scar ruptures. This drawback for a subsequent pregnancy should be met by the single row technique. It was applied in 1434 women from 1962 to 1974. All of them had lower segment cesarian sections. Only 3 harmless ruptures occurred in this group. The clinical course of 12 scar ruptures after terraced uterotomy closure was less favourable. In 6 cases a pregnant uterus ruptured without previous operation. Clinical results are compared. This backs the technique practised. In 5 patients the ruptured uterus could be repaired in the same way as in cesarian section. Hysterectomy, however, was the usual treatment. The risk of rupture after classical cesarian section is lowered by the technique described. This applies to the surgical treatment of uterus duplex as well.

    The effect of the constant illumination on the development of spontaneous tumors in female 129/Sv mice was investigated. Forty-six female 129/Sv mice starting from the age of 2 mo were kept under standard light/dark regimen [12 h light (70 lx):12hr dark; LD, control group], and 46 of 129/Sv mice were kept under constant illumination (24 h a day, 2,500 lx, LL) from the age of 5 mo until to natural death. The exposure to the LL regimen significantly accelerated body weight gain, increased body temperature as well as acceleration of age-related disturbances in estrous function, followed by significant acceleration of the development of the spontaneous uterine tumors in female 129/Sv mice. Total tumor incidence as well as a total number of total or malignant tumors was similar in LL and LD group (p > 0.05). The mice from the LL groups survived less than those from the LD group (χ2 = 8.5; p = 0.00351, log-rank test). According to the estimated parameters of the Cox’s regression model, constant light regimen increased the relative risk of death in female mice compared with the control (LD) group (p = 0.0041). The data demonstrate in the first time that the exposure to constant illumination was followed by the acceleration of aging and spontaneous uterine tumorigenesis in female 129/Sv mice. PMID:23656779

    The spontaneous emergence of contraction-inducing electrical activity in the uterus at the beginning of labor remains poorly understood, partly due to the seemingly contradictory observation that isolated uterine cells are not spontaneously active. It is known, however, that the expression of gap junctions increases dramatically in the approach to parturition, by more than one order of magnitude, which results in a significant increase in inter-cellular electrical coupling. In this paper, we build upon previous studies of the activity of electrically excitable smooth muscle cells (myocytes) and investigate the mechanism through which the coupling of these cells to electrically passive cells results in the generation of spontaneous activity in the uterus. Using a recently developed, realistic model of uterine muscle cell dynamics, we investigate a system consisting of a myocyte coupled to passive cells. We then extend our analysis to a simple two-dimensional lattice model of the tissue, with each myocyte being coupled to its neighbors, as well as to a random number of passive cells. We observe that different dynamical regimes can be observed over a range of gap junction conductances: at low coupling strength, corresponding to values measured long before delivery, the activity is confined to cell clusters, while the activity for high coupling, compatible with values measured shortly before delivery, may spread across the entire tissue. Additionally, we find that the system supports the spontaneous generation of spiral wave activity. Our results are both qualitatively and quantitatively consistent with observations from in vitro experiments. In particular, we demonstrate that the increase in inter-cellular electrical coupling observed experimentally strongly facilitates the appearance of spontaneous action potentials that may eventually lead to parturition.

    Spontaneous oesophageal rupture after swallowing a bolus of food is a very rare condition. In resource-limited settings, it is very challenging to diagnose this condition especially when its presentation is atypical. Its prognosis is very poor when diagnosis is delayed due to risk of mediastinitis. We report a case of 37-year-old man who was admitted to our hospital complaining of sudden onset of chest tightness and pain after a meal 8 h prior to admission. Urgent chest radiograph revealed right hydropneumothorax with collapsed lung. Water-seal drainage was established gushing 1200 ml of food materials. Definitive diagnosis of oesophageal rupture was reached after post-mortem.

    This article describes the case of spontaneous splenic rupture as a rare complication of infection with Babesia species. We will discuss the symptomatology that this disease could present along with both surgical and non-surgical management approaches. Babesia infection often presents with mild to moderate symptoms, but can rapidly progress to significant injury including splenic rupture. The first case reported in a medical journal was in 2007. Treatment usually involves a two-drug regimen; clindamycin plus quinine, or atovaquone plus azithromycin (as in our patient). If hemodynamic stability is present, a primary non-surgical treatment may be especially beneficial since splenectomy may worsen optimal immunologic function and the infection itself.

  10. Spontaneous Bladder Rupture and Cytomegalovirus Infection Complicating Renal Transplantation: Cause or Coincidence?

    The high incidence of surgical complications following renal transplantation is well known. Urologic complications, however, present some of the most challenging problems to the transplant surgeon. The authors present here a detailed case report of spontaneous (delayed) bladder rupture (SDBR) which occurred 90 days after kidney transplantation in a recipient with cytomegalovirus infection (CMV). Urinary catheter drainage is recommended in preference to surgical intervention for the successful correction of SDBR. It is postulated further that, despite a negative bladder biopsy, CMV may have infiltrated the bladder and contributed to this “spontaneous” bladder wall rupture.

    Spontaneous rupture of hepatocellular carcinoma (HCC) is a potentially fatal presentation of the disease. Although many options for treatment exist, Yttrium-90 transcatheter arterial radioembolization has not previously been reported. We report a case of a 92-year-old woman found to have a ruptured HCC treated with radioembolization that showed no viable tumor and no extrahepatic disease at 2 years. While further studies are warranted, this patient's clinical course may suggest that radioembolization may be an additional palliative treatment option in these patients.

    We report a case of sudden death from hemopericardium consequent to spontaneous rupture of the right ventricle in a 49-year-old chronic chagasic woman. To our knowledge, this is the third reported case of spontaneous cardiac rupture with chagasic cardiomyopathy. In our case we believe that the thinning of the anterior right ventricular wall, its large ray curvature and the increased ventricular pressure were factors favoring the rupture. There was no infarction and the chronic cardiopathy was significant. It caused the thinning of the rupture region through chronic myocarditis.

    Spontaneous rupture of the urinary bladder is a rare entity. This is, in part, the cause for the low rate of correct preoperative diagnosis, the high rate of delayed diagnosis, morbidity and mortality. We report a case of spontaneous rupture of the urinary bladder in an adult patient, complicated by extensive fascitis of the abdominal wall. The stormy course and long hospitalization in the case described are characteristic of patients with spontaneous bladder rupture and warrant a high index of suspicion in order to achieve an early diagnosis.

    To report the spontaneous rupture of a renal cyst into the adjacent pyelocalyceal collecting system. We present the case of a 47 year old woman with a 17 centimeter simple renal cyst (Bosniak I) as well as ipsilateral nephrolithiasis. The patient had a febrile urinary tract infection with flank pain. A subsequent CT scan revealed that this cyst spontaneously ruptured into the renal pelvis. Follow up evaluations showed the former cyst has decreased in size and contain thick and nodular calcifications. At present it is a Bosniak IIF cyst. Simple renal cysts can spontaneously rupture and drain into the adjacent renal collecting system.

  15. Spontaneous adrenal pheochromocytoma rupture complicated by intraperitoneal hemorrhage and shock

    PubMed Central

    2011-01-01

    MEN2A is a hereditary syndrome characterized by medullary thyroid carcinoma, hyperparathyroidism, and pheochromocytoma. Classically patients with a pheochromocytoma initially present with the triad of paroxysmal headaches, palpitations, and diaphoresis accompanied by marked hypertension. However, although reported as a rare presentation, spontaneous hemorrhage within a pheochromocytoma can present as an abdominal catastrophe. Unrecognized, this transformation can rapidly result in death. We report the only documented case of a thirty eight year old gentleman with MEN2A who presented to a community hospital with hemorrhagic shock and peritonitis secondary to an unrecognized hemorrhagic pheochromocytoma. The clinical course is notable for an inability to localize the source of hemorrhage during an initial damage control laparotomy that stabilized the patient sufficiently to allow emergent transfer to our facility, re-exploration for continued hemorrhage and abdominal compartment syndrome, and ultimately angiographic embolization of the left adrenal artery for control of the bleeding. Following recovery from his critical illness and appropriate medical management for pheochromocytoma, he returned for interval bilateral adrenal gland resection, from which his recovery was unremarkable. Our review of the literature highlights the high mortality associated with the undertaking of an operative intervention in the face of an unrecognized functional pheochromocytoma. This reinforces the need for maintaining a high index of suspicion for pheochromocytoma in similar cases. Our case also demonstrates the need for a mutimodal treatment approach that will often be required in these cases. PMID:21843357

    We report the clinical and imaging findings in two elderly female patients with spontaneous rupture of the distal iliopsoas tendon from the lesser trochanter of the femur. We emphasize the key contribution of magnetic resonance (MR) imaging to this diagnosis and provide an anatomic correlation. Spontaneous rupture of the distal iliopsoas tendon should be kept in mind in the differential diagnosis of acute groin pain in the elderly. MR imaging enables positive diagnosis, by showing mass effect on the anterior aspect of the hip joint, proximal muscle thickening, and abnormal signal intensity, and by demonstrating interruption of the psoas tendon, whereas the distal insertion of the lateral portion of the iliacus muscle remains muscular and is preserved.

    To evaluate the risk factors and clinical outcomes in patients with spontaneous rupture of pyogenic liver abscess (PLA). A total of 602 patients diagnosed with PLA between January 2004 and July 2013 were retrospectively analyzed. Among them, 23 patients experienced a spontaneous rupture of liver abscess (SRLA). The prevalence of SRLA was 3.8%. Using multivariate analysis, liver cirrhosis (OR 4.651, P = 0.009), gas-forming abscesses (OR 3.649, P = 0.026), abscess ≥6 cm in diameter (OR 10.989, P = 0.002) and other septic metastases (OR 1.710, P = 0.047) were risk factors for SRLA. Regarding the site of rupture, 20 (87.0%) patients had a localized rupture, specifically, subphrenic abscess in 3 (13.0%), peri-hepatic abscess in 10 (43.5%), localized peritoneal abscess in 3 (13.0%) and empyema in 4 (17.5%); and the other 3 (13%) had peritonitis. Ruptures resulting in peritonitis require urgent surgery, whereas localized ruptures were managed with surgical or percutaneous drainage in addition to appropriate antibiotics. The in-hospital mortality rate of SRLA was 4.3%. Patients with cirrhosis, having abscess ≥6 cm in diameter, gas-forming abscesses and other septic metastases in those with PLA should be monitored closely and may need early intervention for SRLA. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Pyogenic liver abscess is a rare cause of hospitalization, related to a mortality rate ranging between 15% and 19%. Treatment of choice is represented by image-guided percutaneous drainage in combination with antibiotic therapy but, in some selected cases, surgical treatment is necessary. In extremely rare cases, spontaneous rupture of liver abscess may occur, free in the peritoneal cavity or in neighboring organs, an event which is generally considered a surgical emergency. A 95-years-old woman was hospitalized with fever, upper abdominal pain, mild dyspepsia and massive swelling of the anterior abdominal wall. Computed tomography revealed an oval mass located in the abdominal wall of 12cm×14cm×7cm, in continuity with an abscess of the left hepatic lobe. Because Proteus mirabilis was detected in both the liver abscess and the abdominal wall abscess, the patient was diagnosed with a ruptured pyogenic liver abscess. After spontaneous drainage to the exterior of the hepato-parietal abscess, she was successfully treated with antibiotics alone. Pyogenic liver abscess is a serious and life-threatening illness. Abscess rupture might occur. Many authors consider this complication a surgical emergency, but the site of abscess rupture changes the clinical history of the disease: in case of free rupture into the peritoneum, emergency surgery is mandatory, while a rupture localized in neighboring tissues or organs can be successfully treated by a combination of systemic antibiotics and fine needle aspiration and/or percutaneous drainage of the abscess.

    INTRODUCTION Liver rupture is a serious event that is most commonly due to blunt abdominal trauma. We present a case of peliosis hepatis in a patient admitted for acute pyelonephritis who developed hemoperitoneum due to spontaneous hepatic rupture from this rare liver condition. PRESENTATION OF CASE We report a 44 year-old woman who presented to our hospital with acute pyelonephrititis and hemoperitoneum due to spontaneous hepatic rupture from peliosis hepatis. Physicians should be aware of this rare condition in patients who present with non-traumatic hepatic rupture with hemoperitoneum. DISCUSSION PH should be considered in all patients with known risk factors who present with typical morphological changes or a hepatic mass, especially when the cause of sudden intraperitoneal hemorrhage is obscure. CONCLUSION Peliosis hepatis is most often asymptomatic and an incidental finding at autopsy. In symptomatic patients, surgery should be reserved for those patients whose hemorrhage is-life-threatening. Familiarity with the imaging characteristics can help in earlier diagnosis of peliosis hepatis. PMID:23562904

    Patient: Male, 45 Final Diagnosis: Atraumatic urinary bladder rupture Symptoms: Drowsiness • diffuse abdominal pain • vomiting Medication: None Clinical Procedure: CT cystogram • exploratory laparotomy • urinary bladder repair Specialty: Urology Objective: Unusual clinical course Background: Spontaneous rupture of the urinary bladder (SRUB) secondary to alcohol intoxication is an uncommon presentation with high morbidity and mortality. Herein, we reported a rare case of spontaneous atraumatic rupture of the urinary bladder due to alcohol intoxication. Case Reports: A 45-year-old Sri Lankan man presented with drowsiness, diffuse abdominal pain, vomiting with odor of alcohol, and urinary retention 24 hours prior to the index admission. CT cystogram confirmed the urinary bladder rupture at the dome, which was repaired through exploratory laparotomy. Conclusions: An SRUB patient with alcohol abuse often presents with non-specific symptoms due to absence of a traumatic event, which results in missed or delayed-diagnosis. Early diagnosis and management of SRUB is crucial for uneventful recovery. PMID:26522816

    Pheochromocytoma crisis is a life-threatening situation. Herein we report a case of catecholamineinduced crisis caused by the rupture of cystic pheochromocytoma. A 76-year-old man with hypertension was referred to our hospital because of a cystic tumor in the retroperitoneal space adjacent to the aorta, which was suspicious of pheochromocytoma. Two days after admission, lower abdominal pain suddenly appeared, followed by hypertension with systolic pressure of 260 mmHg. Computed tomography revealed that the cystic tumor was ruptured spontaneously, leading to diagnosis of pheochromocytoma crisis. His blood pressure was successfully managed by medical treatment and he could recover from crisis. After adequate medical preparation by an α-adrenergic blocker, the tumor was successfully removed by laparoscopy, though the adhesion around the tumor was severe. To our knowledge adrenergic crisis caused by spontaneous rupture of cystic pheochromocytoma is rare, but we have to keep in mind that cystic pheochromocytoma can cause life-threatening crisis by the release of catecholamine due to rupture.

    Anomalies of the fetal urachus are rare. Normally, the postnatal urachus presents as a fibrous band extending from the bladder to the umbilicus. Urachal cysts may occur in postnatal life. Spontaneous perforation of urachal cysts is a very rare condition, which clinically may not be distinguishable from other acute abdominal conditions. We report a case of a 63-year-old male with a history of recurrent urinary tract infections and a bladder rupture caused by a spontaneous perforation of an infected urachal cyst. The symptomatology showed abdominal rigidity and pain, a palpable mass in the lower abdomen, and hematuria. Laboratory findings showed leukocytosis and an increased CRP level. The bladder rupture was confirmed by cystography. Bacteriologic examination identified Proteus vulgaris, Corynebacterium species, and Klebsiella pneumoniae. Most of the published cases in the literature report about intraperitoneal perforation of infected urachal cysts. In the present case, we found a spontaneous perforation of an infected urachal cyst leading to an extraperitoneal bladder rupture with an extraperitoneal limitation of the infection. The definitive therapy was complete surgical excision including a cuff of the bladder, drainage, and systemic broad-spectrum and local application of antibiotics. The further course was uneventful.

    Introduction Idiopathic spontaneous intra-abdominal haemorrhage is a rare, but challenging condition, associated with high mortality if not managed appropriately. The preoperative diagnosis is difficult, despite the recent advances in imaging. We present the clinical manifestations of this condition, as well as the available diagnostic and therapeutic modalities. Presentation of case We report a case of a spontaneously ruptured dissecting aneurysm of the middle colic artery, which was managed with an emergency laparotomy and aneurysmatectomy. Interestingly, no evidence of vasculitis, infection or collagen disease was discovered during the histopathology examination of the specimen. Discussion The treatment of idiopathic spontaneous intra-abdominal haemorrhage revolves around patient resuscitation and management of the source of bleeding. In case of a ruptured aneurysm of the middle colic artery, the surgical management includes emergency laparotomy, arterial ligation and resection of the aneurysm. Transarterial embolisation has been suggested as a safe and less invasive alternative approach. Conclusion A ruptured middle colic artery aneurysm should be included in the differential diagnosis of any unexplained intra-abdominal haemorrhage. Aneurysmatectomy is the treatment of choice, with radiologic interventional techniques gaining ground in the management of this entity. PMID:22096715

    Nontraumatic spontaneous splenic rupture (NSSR) has been encountered much more rarely compared with the traumatic splenic rupture. Although NSSR generally emerges in dialysis patients on account of such causes as the use of heparin during hemodialysis, uremic coagulopathy, infections, and secondary amyloidosis. Herein, we aimed to present a case of spontaneous splenic rupture which had developed soon after the inclusion of the case suffering from end-stage renal disease in routine hemodialysis program in the absence of any trauma or other prespecified risk factors for splenic rupture. A 55-year-old male patient was admitted to our hospital to have the ureteral double J stent removed. The operation was completed without any complication. Complaining an abdominal pain more prominent in the left upper abdominal quadrant in the first postoperative day, the patient underwent a through physical examination which disclosed abdominal distension, widespread tenderness, and rebound and defense positivity. The abdominal tomography depicted 122 × 114 × 95 mm lesion compatible with a hematoma. On the basis of these findings, an emergency exploratory operation was decided to be performed. Following clearance of the retroperitoneal hematoma, splenectomy was implemented. Experiencing progressive deterioration in his clinical status despite antibiotherapy, the patient unfortunately died of sepsis with multiorgan failure on the 25(th) postoperative day. In conclusion, NSSR is such an entity that may be missed out, can pursue variable clinical courses, and requires emergency therapy upon definitive diagnosis. The possibility of spontaneous bleedings should be kept in mind in any case with the history of hyperuricemia even in the absence of overt trauma, no matter if they are included in routine hemodialysis or not.

  11. Staggered-grid split-node method for spontaneous rupture simulation

    Dalguer, Luis A.; Day, Steven M.

    2007-02-01

    We adapt the traction-at-split-node method for spontaneous rupture simulations to the velocity-stress staggered-grid finite difference scheme. The staggered-grid implementation introduces both velocity and stress discontinuities via split nodes. The staggered traction components on the fault plane are interpolated to form the traction vector at split nodes, facilitating alignment of the vectors of sliding friction and slip velocity. To simplify the split-node partitioning of the equations of motion, spatial differencing is reduced from fourth to second order along the fault plane, but in the remainder of the grid the spatial differencing scheme remains identical to conventional spatially fourth-order three-dimensional staggered-grid schemes. The resulting staggered-grid split node (SGSN) method has convergence rates relative to rupture-time, final-slip, and peak-slip-velocity metrics that are very similar to the corresponding rates for both a partly staggered split-node code (DFM) and the boundary integral method. The SGSN method gives very accurate solutions (in the sense that errors are comparable to the uncertainties in the reference solution) when the median resolution of the cohesive zone is 4.4 grid points. Combined with previous results for other grid types and other fault-discontinuity approximations, the SGSN results demonstrate that accuracy in finite difference solutions to the spontaneous rupture problem is controlled principally by the scheme used to represent the fault discontinuity, and is relatively insensitive to the grid geometry used to represent the continuum. The method provides an efficient and accurate means of adding spontaneous rupture capability to velocity-stress staggered-grid finite difference codes, while retaining the computational advantages of those codes for problems of wave propagation in complex media.

  12. Fault steps and the dynamic rupture process: 2-D numerical simulations of a spontaneously propagating shear fracture

    Fault steps may have controlled the sizes of the 1966 Parkfield, 1968 Borrego Mountain, 1979 Imperial Valley, 1979 Coyote Lake and the 1987 Superstition Hills earthquakes. This project investigates the effect of fault steps of various geometries on the dynamic rupture process. The authors have used a finite difference code to simulate spontaneous rupture propagation in two dimensions. They employ a slip-weakening fracture criterion as the condition for rupture propagation and examine how rupture on one plane initiates rupture on parallel fault planes. The geometry of the two parallel fault planes allows for stepover widths of 0.5 to 10.0 m and overlaps of {minus}5 to 5 km. Results demonstrate that the spontaneous rupture on the first fault segment continues to propagate onto the second fault segment for a range of geometries for both compressional and dilational fault steps. A major difference between the compressional and dilational cases is that a dilational step requires a longer time delay between the rupture front reaching the end of the first fault segment and initiating rupture on the second segment. Therefore this dynamic study implies that a compressional step will be jumped quickly, whereas a dilational step will cause a time delay leading to a lower apparent rupture velocity. The authors also find that the rupture is capable of jumping a wider dilational step than compressional step.

    To summarize the application and experience of repairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor. Between January 2011 and December 2013, 31 patients with spontaneous Achilles tendon rupture were treated by part-Kessler technique with suture anchor. Of 31 cases, 23 were male and 8 were female, aged 16-53 years (mean, 38 years). The left side was involved in 15 cases and the right side in 16 cases. The causes of injury included sudden heel pain and walking weakness during sports in 22 cases; no surefooted down-stairs, slip, and carrying heavy loads in 9 cases. The distance from broken site to the calcaneus adhension of Achilles tendon was 3-6 cm (mean, 4.2 cm). The time from injury to operation was 7 hours to 4 days (mean, 36.8 hours). All incisions healed by first intention without nerve injury or adhering with skin. The patients were followed up 6-24 months (mean, 15 months). All patients could complete 25 times heel raising without difficulty at 6 months after operation. No Achilles tendon rupture occurred again during follow-up. At 6 months after operation, the range of motion of the ankle joint in dorsiflexion and plantar flexion showed no significant difference between normal and affected sides (t=0.648, P=0.525; t=0.524, P=0.605). The circumference of the affected leg was significantly smaller than that of normal leg at 6 months after operation (t=2.074, P=0.041), but no significant difference was found between affected and normal sides at 12 months after operation (t=0.905, P=0.426). The American Orthopedic Foot and Ankle Society (AOFAS) scores at 6, 12, 18, and 24 months after operation were significantly higher than preoperative score (P<0.05); the score at 6 months after operation was significantly lower than that at other time points (P<0.05), but no significant difference was shown between the other time points (P>0.05).

    Background. Spontaneous rupture of an ovarian artery aneurysm is a rare but usually life-threatening event. It is most often associated with pregnancy or fibroids. Our case followed a normal vaginal delivery and then a delayed presentation with features similar to other less life-threatening postpartum conditions. The diagnosis could have been missed but for the meticulous and timely interventions which avoided catastrophic outcome. Case. This is a case of a multiparous woman with rupture of a left ovarian artery aneurysm, causing massive retroperitoneal hemorrhage and hematoma that required a combination of arterial embolization, percutaneous CT scan guided drainage, and surgical evacuation of the hematoma. Conclusion. Spontaneous rupture of ovarian artery should be considered as one of the differential diagnoses in the immediate postpartum period especially when the clinical symptoms do not correlate with the amount of blood loss. A high index of suspicion, prompt diagnosis, intervention, and a multidisciplinary approach in the management were the elements of a successful outcome in this case. PMID:27034862

    Spontaneously ruptured hepatocellular carcinoma (HCC) with hemoperitoneum has a poor prognosis, especially in cases of cirrhosis. Patients usually present to emergency rooms (ERs) with acute abdomen. The aim of the present study was to determine the factors affecting mortality and to compare the prognosis of conservative treatment, transcatheter arterial embolization (TAE), or hepatectomy in these situations. Fifty-four patients with spontaneously ruptured HCC diagnosed between January 2004 and August 2010 were enrolled in this retrospective review of clinical data. Grouping by survival or mortality, univariate and multivariate analyses of factors affecting 30-day mortality, and long-term survival were conducted. The outcomes of the various treatments were analyzed. After primary fluid resuscitation in the ER, 6 of 54 patients underwent conservative treatment. Emergency hepatectomy was performed on 19 patients; TAE was used for 29 patients, 18 of whom received staged hepatectomy thereafter. Poor liver function, prolonged international normalized ratio (INR), and conservative treatment were associated with increased 30-day mortality. Logistic regression analysis of cumulative survival revealed that INR ≥ 1.4, multiple intrahepatic HCC, and conservative treatment were related to poorer long-term survival. The patients who received hepatectomy, either immediate or staged after TAE, had higher survival rates of 85.2 % at 30 days and 62.2 % at 1 year. The treatment of ruptured HCC should be tailored to the individual case. Prolonged survival is possible in patients with preserved liver function through curative liver resection. Emergency physicians, radiologists, and surgeons play essential roles in managing these patients.

    Rudimentary uterine horn pregnancy is rare and, to our knowledge, has not been previously reported in Cameroon. We herein report the case of a 22 year old second gravida referred for acute abdominal pain at 17 weeks of gestation. Physical examination revealed hemoperitoneum with hypovolemic shock. After resuscitation, an emergency exploratory laparotomy was done and we found hemoperitoneum of 3,500 milliliters, a bicornuate uterus with a ruptured right rudimentary communicating horn containing a non viable foetus. There were no other abnormalities. We performed an excision of the rudimentary horn with ipsilateral salpingectomy. Post-operative course was uneventful and the woman was discharged seven days later. This case emphasizes the importance of good antenatal care to avoid complications. PMID:25400853

    A 25-year-old previously healthy man presented to our Emergency Department with shortness of breath and epigastric pain after swallowing a boneless chicken nugget one hour prior to presentation. Physical examination revealed epigastric rigidity and tenderness. Serology was normal except for mildly elevated bilirubin and amylase. Computed tomography (CT) scan of the chest revealed a distal esophageal rupture with accompanying pneumomediastinum and left-sided pleural effusion. Treatment was initiated with administration of intravenous fluids and broad-spectrum antibiotics. Subsequently, an esophageal stent was inserted endoscopically in addition to VATS (Video-Assisted Thoracoscopic Surgery) drainage of the left-sided pleural space. This case illustrates an unusual presentation of Boerhaave's syndrome: a rare and life-threatening form of noniatrogenic esophageal rupture most often preceded by forceful vomiting. Our case demonstrates that physicians should maintain an index of suspicion for spontaneous esophageal rupture in patients presenting with shortness of breath and epigastric pain even in the absence of preceding vomiting, cough, or seizure. Additionally, ingestion of boneless, shell-less foods may be sufficient to cause rupture in individuals without underlying esophageal pathology. CT scan of the thorax and upper abdomen should be performed in these patients to rule out this rare and life-threatening diagnosis. PMID:26949552

    Spontaneous oesophageal rupture after swallowing a bolus of food is a very rare condition. In resource-limited settings, it is very challenging to diagnose this condition especially when its presentation is atypical. Its prognosis is very poor when diagnosis is delayed due to risk of mediastinitis. We report a case of 37-year-old man who was admitted to our hospital complaining of sudden onset of chest tightness and pain after a meal 8 h prior to admission. Urgent chest radiograph revealed right hydropneumothorax with collapsed lung. Water-seal drainage was established gushing 1200 ml of food materials. Definitive diagnosis of oesophageal rupture was reached after post-mortem. PMID:26421158

    Aneurysms of the cavernous segment of the internal carotid artery (ICA) are believed to have a low risk of subarachnoid haemorrhage (SAH), given the confines of the dural rings and the anterior clinoid process. The risk may be greater when the bony and dural protection has been eroded. We report a case of spontaneous SAH from rupture of a cavernous ICA aneurysm in a patient whose large prolactinoma had markedly decreased in size as the result of cabergoline treatment. After passing a balloon test occlusion, the patient underwent successful endovascular vessel deconstruction. This case suggests that an eroding skull base lesion may distort normal anterior cranial base anatomy and allow communication between the cavernous ICA and subarachnoid space. The potential for SAH due to cavernous ICA aneurysm rupture should be recognised in patients with previous pituitary or other skull base lesions adjacent to the cavernous sinus.

    A 23 year old male kick boxer presented with a 24 hour history of pain and being unable to extend the interphalangeal joint of the left thumb. There was no history of trauma or any other risk factor for spontaneous rupture of the extensor pollicis longus tendon. On the previous day, he had been doing reverse press ups on the dorsum of his hands with his wrists hyperflexed as part of his training for kick boxing. At operation the extensor pollicis longus tendon was found to be divided at the level of the dorsal tubercle of the radius and was not directly repairable. The treatment was an extensor indicis proprius transfer. We suggest that the cause of the tendon rupture was direct pressure on the dorsal tubercle of the radius sustained while performing reverse press ups.

    This article describes the case of spontaneous splenic rupture as a rare complication of infection with Babesia species. We will discuss the symptomatology that this disease could present along with both surgical and non-surgical management approaches. Babesia infection often presents with mild to moderate symptoms, but can rapidly progress to significant injury including splenic rupture. The first case reported in a medical journal was in 2007. Treatment usually involves a two-drug regimen; clindamycin plus quinine, or atovaquone plus azithromycin (as in our patient). If hemodynamic stability is present, a primary non-surgical treatment may be especially beneficial since splenectomy may worsen optimal immunologic function and the infection itself. PMID:26839774

    Uterine rupture is one of the most catastrophic complications during pregnancy. It is a rare complication in developed countries but a frequent cause of maternal and perinatal morbidity and mortality in Africa. Uterine rupture occurs in 1.6% of patients suffering blunt abdominal trauma. Here we report a unique case of complete fundal rupture of the unscarred uterus following fall from motorcycle in 39-week-pregnant mother who was managed with total abdominal hysterectomy and left salpingo-oophorectomy and survived, though fetus died before intervention. We also reviewed similar cases reported from different parts of Africa. This is a preventable complication had the woman been properly instructed on transportation safety during her antenatal care visits. PMID:26576307

    Spontaneous rupture of hepatocellular carcinoma hemorrhage is life-threatening. The aim of the present study was to retrospectively analyze the effect of gelatin sponge microparticles (GSMs) of various diameters on the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSMs serve as embolization agents by transcatheter arterial chemoembolization (TACE), and the current study analyzed their safety and efficacy. Data from a total of 13 cases of spontaneous rupture of hepatocellular carcinoma hemorrhage, who were treated with GSM-TACE at the Affiliated Zhongshan Hospital of Dalian University (Dalian, China) between August 2010 and June 2014, were collected. Post-operative complications were classified according to the National Cancer Institute Common Terminology Criteria. Review computed tomography was conducted 1, 3 and 6 months after GSM-TACE treatment in order to determine the occurrence of re-bleeding; the tumor response was evaluated based on the Modified Response Evaluation Criteria In Solid Tumors and the expression levels of α-feroprotein. The patients were followed-up for 1–6 months (average, 5.15±1.67 months). Following GSM-TACE treatment, 13 cases reached successful hemostasis without technical complications. The survival rates 1, 3 and 6 months after treatment were 76.9 (10/13), 61.5 (8/13) and 53.8% (7/13), respectively; the objective response rates were 61.6, 53.9 and 38.5%, respectively. The primary post-operative complications were pain (100%), nausea and vomiting (69.2%), and fever (53.8%). Among the 13 patients, 2 cases underwent surgical excision 10 and 30 days after GSM-TACE, and 1 case experienced re-bleeding 3 months after treatment, after which the patient received a second treatment with TACE and successful achieved hemostasis. In conclusion, GSM-TACE of various diameters is a safe and effective method in the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSM-TACE is able to achieve immediate

    Cases of spontaneous regression of cerebral aneurysm remnant after incomplete surgical clipping have been rarely reported. This paper reports the regression of an aneurysm remnant after incomplete surgical clipping during postsurgical follow-up. A 50-year-old male presented with subarachnoid hemorrhage because of rupture of an anterior communicating artery aneurysm. An emergency clipping of the aneurysm was performed. A cerebral angiography, which was performed two weeks postoperatively, revealed an aneurysm remnant. The patient refused additional treatment and was discharged without apparent neurological deficit. One-year follow up cerebral angiography demonstrated a partially regressed aneurysm remnant. PMID:28184353

    Spontaneous rupture of an aneurysm of the ovarian artery is usually considered a rare complication of pregnancy and the puerperium. However, we observed this emergent condition in a 51-year-old postmenopausal woman. We report here our experiences and consider lessons about diagnosis and management that can be drawn from this case and 5 other published cases in multiparous middle-aged women. These lessons include application of contrast-enhanced computed tomography to focus emergent care, surgical intervention, and association with systemic inflammatory response syndrome. We also consider how the cases might shed new light on the pathogenesis and evolution of this condition.

    Peritonitis after spontaneous rupture of pyonephrosis into the peritoneal cavity is a rare complication, usually diagnosed intraoperatively. We report a case of a woman presenting with left lumbar pain and fever during pregnancy. On admission, ultrasonography showed a pregnancy with fetal activity for 16 weeks, and pyonephrosis in the left kidney, but on a normal right kidney. After antibiotic therapy and upper urinary, tract stenting renal drainage revealed purulent urine, fever persisted with acute abdomen. Clinical and radiological assessment showed features of acute peritonitis with pyonephrosis. Treatment consisted of laparotomy with nephrectomy and abdominal lavage and drainage. The postoperative complication was septic shock requiring resuscitation and artificial ventilation and prolonged convalescence.

    Papillary renal cell carcinoma (pRCC) represents the second most common type of malignant renal epithelial tumor (represents the 10% of the kidney’s carcinoma) and can be subclassified in the basophile type I and eosinophile type II. We report a clinical case of spontaneous rupture of the kidney affected by multifocal (42 tumors foci) pRCC in a young man 53 years old, without showing earlier specific cancer signs and symptoms. Prognosis for type I pRCC is better than type II pRCC, but it is anyway related to the tumoral grade, to the tumoral stage and to the diagnostic precocity. Signs and symptoms are very similar to those characterizing the more frequent clear cell carcinoma. Nevertheless in the 40% of the cases the lesion is asymptomatic. To our knowledge, this is the first case of spontaneous rupture of the kidney affected by multifocal pRCC in literature without showing earlier specific cancer signs and symptoms. PMID:25568749

    Moderate physical exercise (PE) combined with metabolic treatment (MT) (antioxidants and l-arginine) are well known to reduce atherosclerotic lesion formation in hypercholesterolemic mice. However, the long-term beneficial effects on unstable atheroma remain poorly understood. We started early PE training in large groups of 6-week-old hypercholesterolemic mice (by graduated swimming) alone or in combination with nutritional supplementation (1.0% vitamin E added to the chow and 0.05% vitamin C and 6% l-arginine added to the drinking water). Inactive controls did not receive PE. The spontaneous development of atherosclerotic plaque rupture (associated with advanced atherosclerosis) and survival rates were evaluated. Moderate PE elicited an increase in plasma levels of nitric oxide. Early combined treatment with PE and MT in the hypercholesterolemic mice significantly reduced lesions (also detected noninvasively at 10 months) and spontaneous atherosclerotic plaque rupture and prolonged survival more effectively than each intervention alone. Thus, early concerted actions of MT and PE improve the natural history of atherosclerotic lesions and reduce the plaque instability in hypercholesterolemic mice.

    OBJECTIVE The purpose of this study was to compare the transcriptome between the site of membrane rupture and the chorioamniotic membranes away from the site of rupture. STUDY DESIGN The transcriptome of amnion and chorion (n =20 each) from and distal to the site of rupture from women with spontaneous labor and vaginal delivery at term after spontaneous rupture of membranes was profiled with Illumina HumanHT-12 microarrays. Selected genes were validated with the use of quantitative reverse transcription–polymerase chain reaction. RESULTS Six hundred seventy-seven genes were differentially expressed in the chorion between the rupture and nonrupture sites (false discovery rate <0.1; fold change >1.5). Quantitative reverse transcription–polymerase chain reaction confirmed the differential expression in 10 of 14 genes. Enriched biological processes included anatomic structure development, cell adhesion and signal transduction. Extracellular matrix–receptor interaction was the most impacted signaling pathway. CONCLUSION The transcriptome of fetal membranes after spontaneous rupture of membranes in term labor is characterized by region-and tissue-specific differential expression of genes that are involved in signature pathways, which include extracellular matrix–receptor interactions.

    Placenta-percreta causing uterine rupture in unscarred uterus is a rare obstetric surgical emergency that can cause maternal and perinatal morbidity and mortality. A 25-year-old woman presented with abdominal pain for four days. Previously, she had undergone two suction curettages for complete hydatiform moles. Ultrasound revealed a non-viable fetus with an estimated gestational age of 21 weeks and free fluid and coagulum in the abdominal cavity. An emergency laparotomy was performed because of the acute abdomen. At exploration, the placenta had invaded the entire thickness of the myometrium and the non-viable fetus was in the abdominal cavity. The uterus was closed with a double-layer of interrupted sutures and uterine-sparing surgery was performed. The patient was discharged on postoperative day seven. The authors present a case of placenta-percreta in an unscarred uterus complicated with uterine rupture during the second-trimester that was managed successfully with uterine repair. They also review the literature briefly and discuss similar cases managed conservatively in the second-trimester.

    Uterine rupture is a rare but severe complication in obstetrics. A previous C-section is the most important risk factor. Its incidence during labor in women with a previous C-section is of approximately 0.3-0.47%, being potentially severe. We present the case of a pregnant women with a previous C-section who suffered uterine rupture during labor. The rapid assessment and action of the midwife and obstetric team was essential to obtain a successful obstetric outcome, avoiding maternal and fetal mortality; and nursing care given to the mother and the newborn after birth contributed to achieving a normal postpartum. It is necessary to have specific knowledge about this condition that, despite rare, can present insidiously with a potential risk for the mother and the fetus.

    Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01−0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy). Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

    Neonatal outcomes after the maternal obstetric near-miss complications of uterine rupture, abnormally invasive placenta, and emergency peripartum hysterectomy were assessed. This case-control study was conducted as part of the Nordic Obstetric Surveillance Study (NOSS). Data on 211 newborns from 197 deliveries in which an obstetric near-miss complication was involved, were collected prospectively from April 2009 to August 2011 from all Finnish delivery units via questionnaires. Missing cases were obtained from national health registers and confirmed by the clinics. Control populations consisted of all other children born during the same period of time in the Finnish Medical Birth Register (n = 147 551). The number of stillbirths in this cohort was high [n = 8, 3.8% vs. 0.3% among controls, odds ratio (OR) 12.5, 95% confidence interval (CI) 6.32-24.9]. In addition, there were two neonatal deaths. The majority of cases (n = 8, 80%) were connected to uterine rupture. The risk of severe birth asphyxia diagnosis was increased compared with controls (n = 17, 8.1% vs. 0.1%, OR 137, 95% CI 82.7-226). A low umbilical artery pH (<7.05) was also observed among these neonates (28.8% vs. 1.0%, OR 28.7, 95% CI 21.5-38.2). Post-term pregnancies were relatively common among the uterine rupture cases. Adverse neonatal outcomes in the AIP and emergency peripartum hysterectomy cases were associated with preterm deliveries. The prospective data collected from clinicians, combined with the information gathered from national health registers, provided valuable insights into rare maternal near-miss cases. These complications also predisposed stillbirth and neonatal death. In this study, 75% of fetal losses were associated with uterine rupture. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

  17. Spontaneous rupture on natural fractures and seismic radiation during hydraulic fracturing treatments

    2016-07-01

    We extend spontaneous rupture models in earthquake source studies to analyze fluid injection problems. We perform these analyses on a 2-D fracture network model with a propagating hydraulic fracture (HF) and three sets of natural fractures (NFs). We find that it is difficult for NFs that are either parallel or perpendicular to the HF to slip because of little resolved shear stress on them in the prestress field. Shear failure of optimally oriented NFs depends on frictional parameters, such as the critical slip distance in slip-weakening laws. Slip of NFs near the tips of the HF may affect HF opening. Nonsmooth fracture opening generates isolated spiky seismic signals, while unstable frictional slip radiates strong and continuous seismic signals with long-duration coda waves. These results suggest microseismicity may be primarily generated by unstable frictional slip on NFs with some contribution from nonsmooth opening motions on HFs and/or NFs.

    Bleeding resulting from spontaneous rupture of the liver is an infrequent but potentially life threatening complication that may be associated with an underlying liver disease. A hepatocellular carcinoma or hepatic adenoma is frequently reported is such cases. However, hemoperitoneum resulting from a hepatic metastatic thymoma is extremely rare. Here, we present a case of a 62-year-old man with hypovolemic shock induced by ruptured hepatic metastasis from a thymoma. At the first hospital admission, the patient had a 45-mm anterior mediastinal mass that was eventually diagnosed as a type A thymoma. The mass was excised, and the patient was disease-free for 6 years. He experienced sudden-onset right upper quadrant pain and was again admitted to our hospital. We noted large hemoperitoneum with a 10-cm encapsulated mass in S5/8 and a 2.3-cm nodular lesion in the right upper quadrant of the abdomen. He was diagnosed with hepatic metastasis from the thymoma, and he underwent chemotherapy and surgical excision. PMID:27956811

  19. Galerkin boundary integral equation method for spontaneous rupture propagation problems: SH-case

    We develop a Galerkin finite element boundary integral equation method (GaBIEM) for spontaneous rupture propagation problems for a planar fault embedded in a homogeneous full 2-D space. A 2-D antiplane rupture propagation problem, with a slip-weakening friction law, is simulated by the GaBIEM. This method allows one to eliminate the strong singularities from the integral representation of the traction, and to separate explicitly the expression for the traction into an instantaneous component; static and time-dependent components with weakly (logarithmic) singular kernels; and a dynamic component and a quasi-static component, with continuous, bounded, kernels. Simulated results throw light into the performance of the GaBIEM and highlight differences with respect to that of the traditional, collocation, boundary integral equation method (BIEM). Both methods converge with a power law with respect to grid size, with different exponents. There is no restriction on the CFL stability number for the GaBIEM since an implicit, unconditionally stable method is used for the time integration. The error of the approximation increases with the time step, as expected, and it can remain below that of the BIEM.

    Introduction We report the case of a patient with antepartum HELLP syndrome and simultaneous rupture of the right liver lobe. An emergency caesarean section was performed and the liver rupture was managed surgically via perihepatic packing. The mother and her child recovered well and were discharged 19 days after admission. Case Report We describe a case report and review the literature. Based on our own experience and the most common clinical presentations of such patients, we were able to establish an algorithm for managing such cases. Conclusion An association between liver rupture and HELLP syndrome is rare but was previously described in several case reports. In pregnant women with HELLP syndrome and acute onset abdominal pain, a potential spontaneous hepatic rupture should be taken into consideration. PMID:26468317

    Friction laws are typically introduced either based on theoretic ideas or by fitting laboratory experiments that reproduce only a small subset of possible behaviors. Hence it is important to validate the resulting laws by modeling experiments that produce spontaneous frictional behavior. Here we simulate experiments of spontaneous rupture transition from sub-Rayleigh to supershear done by Xia et al. (Science, 2004). In the experiments, two thin Homalite plates are pressed together along an inclined interface. Compressive load P is applied to the edges of the plates and the rupture is triggered by an explosion of a small wire. Xia et al. (2004) link the transition in their experiments to the Burridge-Andrews mechanism (Andrews, JGR, 1976) which involves initiation of a daughter crack in front of the main rupture. Xia et al. have measured transition lengths for different values of the load P and compared their results with numerical simulations of Andrews who used linear slip-weakening friction. They conclude that to obtain a good fit they need to assume that the critical slip of the slip-weakening law scales as P-1/2, as proposed by Ohnaka (JGR, 2003). Hence our first goal is to verify whether the dependence of the critical slip on the compressive load P is indeed necessary for a good fit to experimental measurements. To test that, we conducted simulations of the experiments by using boundary integral methodology in its spectral formulation (Perrin et al., 1995; Geubelle and Rice, 1995). We approximately model the wire explosion by temporary normal stress decrease in the region of the interface comparable to the size of the exploding wire. The simulations show good agreement of the transition length with the experimental results for different values of the load P, even though we keep the critical slip constant. Hence the dependence of the critical slip on P is not necessary to fit the experimental measurements. The inconsistency between Andrews' numerical results

    The authors have documented 50 cases of U.R., out 2,151 normal deliveries. During the same period, 614 surgeries for caesarean sections were performed. The U.R. frequency has been estimated at 1.80%. 98% of the U.R. were referred to us from outside in the vicinity maternities of Niamey. The maximum number of frequencies occurs between the ages of 15-42 years, and in decreasing order, among multiparas (with a parity of 5 and above). Uterine scars are among the principal causing factors. Sub total hysterectomy was the most widely used surgical method (60%). Among the 50 cases, 8 maternal deaths (16%) and 48 fatal deaths were reported (96%). The average length of stay in hospital was between 4 and 7 days. The shortest was 5 day and the longest 17 days. In order to alleviate this dramatic situation, the authors suggest the following measures: the implementation of a family planning programme (to discourage multiparity) a wide information campaign of the population, the insurance of a better treatment of uterus scars, the building of surgical units closer to rural areas, the provision of a better equipment to medical centres, the retraining of medical personnel.

    Few cases of clostridial gas gangrene associated with uterine malignancy have been reported. We report on a 46-year-old woman with clostridial sepsis. On the day of admission due to severe abdominal pain, peritonitis was diagnosed, and computed tomography showed free air in the abdomen. At emergency laparotomy, perforation of the necrotic uterine wall was observed. During hysterectomy, septic shock developed, and life-saving therapy was performed in the intensive care unit after surgery. Pathological examination of the necrotic uterine wall showed grade III endometrial adenocarcinoma of the uterine endometrium (International Federation of Gynecology and Obstetrics stage IIIa) with gas gangrene due to Clostridium perfringens. This report aims to alert gynecologists to the possibility that clostridial gas gangrene of the uterus can occur in patients with peritonitis and intra-abdominal free air. Early recognition and aggressive therapy can save patients' lives.

    Rare side-effects of fluoroquinolone therapy are tendinitis and tendon rupture. Many reports have demonstrated that the concomitant use of corticosteroids, in patients aged 60 years or older, increase the risk substantially. We present a case of spontaneous bilateral Achilles tendon rupture induced by ciprofloxacin and methylprednisolone. A 61-year-old woman was diagnosed with Bronchiolitis Obliterans with Organizing Pneumonia (BOOP) and was started on oral ciprofloxacin 500 mg twice daily for 3 weeks and on oral methylprednisolone 16 mg twice daily for 2 weeks. The diagnosis was made after doctors, rather than stop drug therapy and advise complete rest, had mistakenly prescribed for the woman to undergo physiotherapy and local NSAIDs, thus favoring the onset of tendon ruptures and resulting in surgical and legal implications. Inspired by this case, we also submit a brief review on professional liability in Orthopaedics.

    CT characteristics of spontaneous rupture of HCC (n = 13) were reviewed retrospectively, and the value of emergency CT studies in this disease was evaluated. Especially, tumor protrusion ratio (TPR) and ascitic CT numbers were measured to for comparison with the data for unruptured HCCs and ordinary (e.g. non hemorrhagic) ascites (n = 13). As a result, except for diffuse type HCCs, the TPR was significantly higher than for the unruptured HCCs. Nine cases had intraperitoneal HDAs, and the laterality of the HDAs corresponded with that of the ruptured tumors in 8 cases. Also, the ascitic CT numbers apart from the HDA were still higher than the ordinary ascites. Therefore, a high TPR, HDAs adjacent to the tumor, and elevated ascitic CT numbers are important CT manifestations indicating HCC rupture. Diffuse HCCs, however, require careful clinical evaluation.

    Authors report an uncommon case of spontaneous rupture of common iliac artery in a man 43 years old with Ehlers-Danlos syndrome. The clinical presentation was devious in the beginning and catastrophic after few hours with a haemo-peritoneum and haemorragic shock. The Ehlers-Danlos syndrome is a rare affection of the connective tissue with an incidence of 1/5000, representing one of the most common disorders of the connective tissue. This disease is characterized by the fragility of arteries, intestine and uterus. Its presentation is often catastrophic, with rupture of a big artery, rupture of uterus during pregnancy or bowel perforation. The mean age of death in subjects with Ehlers-Danlos syndrome is 45 years. This syndrome is inherited in most cases in an autosomal dominant manner; 50% of the cases are due to new mutations. A minority of cases, due to deficit of tenascina X, is inherited in an autosomal recessive manner.

    Background. Primary splenic angiosarcoma is a very rare mesenchymal malignant tumor associated with a poor prognosis due to its high metastatic potential. This disease can be easily neglected and spontaneous splenic rupture is a frequent manifestation at the time of diagnosis leading to a poor outcome because of peritoneal dissemination. Case Presentation. We describe the case of a 49-year-old man who presented with asthenia, left upper quadrant abdominal pain, and anemia. Computerized tomography scan showed an enlarged spleen with no nodules and a nontraumatic rupture of the splenic capsule. Splenectomy was performed on account of the severe anemia and histopathology examination showed a primary angiosarcoma. Conclusions. Splenic angiosarcoma should be considered as one of the differential diagnoses in patients with nontraumatic spleen rupture and a specific previous medical history. Regrettably, splenectomy allows for a definitive diagnosis but not a curative treatment. PMID:28261515

    Cavernous hemangioma is the most common benign tumour of the liver and is found quite commonly during abdominal ultrasonography performed for other diseases. It is often asymptomatic and undergoes enlargement in fewer than 10% of cases. Spontaneous rupture of a giant hepatic hemangioma (diameter > 4 cm) with hemoperitoneum occurs very rarely. Only 32 cases have been reported in a recent review of the medical literature, with an operative mortality of more than 35%. We describe a new case of a giant subcapsular hemangioma localised in hepatic segments II and III in an 84-year-old woman, which ruptured spontaneously into the abdominal cavity and presented with hemoperitoneum and hypovolaemic shock. The hemangioma was diagnosed preoperatively by spiral CAT and treated successfully with emergency hepatic bisegmentectomy.

    Background Spontaneous rupture of the kidney is uncommon and is mainly caused by renal tumors. Only a few cases are caused by vasculitis. We report here the first case of spontaneous rupture of kidney resulting from mixed cryoglobulinemia. Case presentation A 44-year-old man presented with sudden onset of fever, acute pulmonary edema, left flank abdominal pain unassociated with trauma, and rapidly progressive renal failure requiring dialysis. Computed tomography of the abdomen revealed a large perirenal hematoma of the left kidney. During conservative surgery, the patient underwent renal biopsy that showed renal vasculitis and membranoproliferative glomerulonephritis with intracapillary microthrombi. Tests were positive for mixed cryoglobulinemia caused by Sjögren’s syndrome. The patient was better after immunosuppressive therapy, with the disappearance of clinical symptoms and the recovery of baseline renal function. Conclusion We report on this case and discuss a possible link between spontaneous rupture of kidney and mixed cryoglobulinemia-associated Sjögren’s syndrome. PMID:27042145

    Hydatid disease is a parasitic infection characterized by cyst formation in any organ, although the liver and lungs are most commonly involved. Hydatid disease of the spleen is uncommon, representing <8% of all human hydatid diseases. Splenic hydatid cysts usually coexist with liver hydatid cysts (secondary form), although the spleen is the primary location (primary form) in some cases. The clinical signs and symptoms of splenic hydatid cysts depend on their size, relationship with adjacent organs, and complications. One of the complications of splenic hydatid cysts is cyst rupture either after trauma or spontaneously as a result of increased intracystic pressure. These cysts may rupture into a hollow organ, through the diaphragm into the pleural cavity, or directly into the peritoneal cavity. A splenic hydatid cyst that ruptures into the peritoneal cavity may cause complications, including signs of peritoneal irritation, urticaria, anaphylaxis, and death, as in our case. Therefore, a hydatid cyst rupture requires both emergency surgery and careful postoperative care. In this study, we present a case of a giant splenic hydatid cyst that ruptured into the peritoneal cavity without any trauma. A review of cases reported in the English literature about splenic hydatid cyst perforation is also discussed.

    We describe the spontaneous rupture of a simple hepatic cyst. A 62-year-old woman was admitted for right upper quadrant pain of sudden onset. The patient denied a history of abdominal trauma. Computed tomography of the abdomen showed a 13-cm-diameter solitary hepatic cyst in the right lobe. Part of the cyst surface was irregular, and the internal echo was heterogeneous. Retained fluid was detected under the liver capsule. Ten days after admission, computed tomography revealed that the volume of fluid retained under the liver capsule had decreased but that the hepatic cyst had enlarged again. The patient was referred to our hospital for further evaluation and treatment. Physical examination revealed mild right upper quadrant pain, but no signs or symptoms of peritonitis or abnormalities of the chest or heart. Percutaneous puncture was performed with a needle and an 8-French pigtail catheter under ultrasonographic guidance. Brown serous fluid was aspirated. After the removal of approximately 1,000 mL of fluid, contrast medium was injected to check for communications between the cyst and the biliary tree and to document the absence of leakage into the peritoneal cavity. After complete aspiration of the cyst fluid, 200 mg of minocycline hydrochloride dissolved in 10 mL of saline was injected into the cyst, and the catheter was flushed with 10 mL of saline (total volume of saline, 20 mL). The catheter was then clamped for 30 minutes. After percutaneous aspiration, the patient's symptoms resolved. Minocycline hydrochloride was injected daily for 7 days, and the catheter was removed. There has been no evidence of recurrence after 2 years.

    During the conduct of a study designed to determine the effect of 3-methylcholanthrene (3-MC), a synthetic polycyclic aromatic hydrocarbon (PAH) that acts through the aryl hydrocarbon receptor (AhR), on uterine contractility in Wistar rats, uterine tumors were identified in both vehicle and 3-MC-treated animals. The objective of the current study was to describe the histological characteristics of these tumors. Sexually mature female rats (110 days old) were treated with 70 micro mol/kg 3-MC or vehicle (olive oil) for 4 days and euthanized by exsanguination. At necropsy uterine tumors were unexpected findings in two vehicle and four 3-MC-treated rats. The tumors appeared as multiple unilateral or bilateral subserosal nodes. No tumors were found in other tissues on gross inspection. Prior to necropsy, tumor-presenting animals were acyclic and arrested in a state of persistent proestrus. Haematoxylin and eosin staining of tumor sections revealed nests of acidophilic granule-containing cells within a highly vascular stroma of the uterine wall below the muscularis. Positive periodic acid Schiff (PAS) staining suggested the presence of glycogen or glycophospholipids within these granules, however, negative PAS diastase staining indicated that the acidophilic bodies were not composed of glycogen. The tumors are histologically similar to human dysgerminomas. We conclude that these tumors are unrelated to treatment and are of a granular type not previously documented in Wistar rats.

    Background Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes. Methods In this cross-sectional study, 200 primiparous women participated having a single pregnancy and cephalic presentation. Uterus contractions were recorded using electronic fetal monitoring at the beginning of the active phase of labor (dilatation 3-5 cm) for 30 min. Fall to rise (F:R) ratio was calculated by determining the duration of returning from a contraction peak to its baseline (fall) and the duration of the rise time from baseline to peak (rise) in two groups. The data were analyzed using t-test and Chi-square test. Results In this study, 162 women had a normal delivery and 38 women had a cesarean (CS) delivery due to the lack of labor progress. The average F:R ratio was 1.13±0.193 seconds in the vaginal delivery group and 1.64±0.301 seconds in the CS group. This difference was statistically significant (P<0.001). The frequency of contractions in the vaginal delivery group was more than the CS group (P=0.008). Conclusion Our findings demonstrated that uterine contractions shapes change; and F:R ratio was higher in the group that lacked labor progress. Therefore, contraction shapes can be used to predict the labor progress.   PMID:25821288

    Hemomediastinum is a rare pathological event. Multiple underlying causes and contributory factors can be identified, such as trauma, malignancy, iatrogenic, bleeding disorder or mediastinal organ hemorrhage. Also, a mediastinal bronchial artery aneurysm may be the source of a hemomediastinum. Hemoptysis is an important directive symptom, however occasionally, patients only present with thoracic pain or symptoms related to extrinsic compression of the airways or esophagus. Using contrast-enhanced computed tomography (CT) of the chest, hemomediastinum can be adequately diagnosed, and the involved vascular structures can be revealed. In case of a (ruptured) bronchial artery aneurysm, transcatheter embolization provides a minimally invasive procedure and is treatment of first choice. In this case report, a 76-year-old female is presented with spontaneous rupture of a mediastinal bronchial artery aneurysm resulting in hemomediastinum causing thoracic pain. Superselective embolization of the left bronchial artery was successfully performed. PMID:26029533

    Aim: The aim of this study was to investigate a relationship between seasonal variation and incidence of type A acute aortic dissection (AAD) and spontaneous abdominal aneurysm rupture (rAAA) in Canton Tuzla, Bosnia and Herzegovina. Patients and methods: A total of 81 cases, 41 AAD and 40 of ruptured AAA were identified from one center over a 6-year, from 2008 till 2013. In 2012 were admitted (45.6% or 36 patients). Results: Seasonal analysis showed that 19(23.4%) patients were admitted in spring, 15(18.5) in summer, 26(32%) in autumn and 21(25.9) in winter. The most frequent period was autumn/winter with 47 or 58% patients. A causal link between atmospheric pressure (AP) and incidence of rAAA and AAD on seasonal and monthly basis was found.

    We present a case of spontaneous rupture of hepatocellular carcinoma (HCC) with poor liver function which was treated by transcatheter arterial embolization (TAE). The patient's bilirubin value was 3.8 mg/dL. The tumor was fed by the right renal capsular artery according to selective arteriography. It was subsequently treated by TAE. With successful TAE, no hepatic failure was related to the treatment. We believe that if tumors are fed only by extrahepatic collateral vessels, TAE may be an effective treatment even in patients with poor liver function.

    Artificial rupture of the membranes during established labor is believed to augment labor progression, but this practice carries the risk of maternal and neonatal infection. A prospective study conducted at De Soysa Hospital for Women in Colombo, Ceylon, in 1995 compared the obstetric performance, perinatal outcome, and risk of neonatal infection in 151 women with spontaneous rupture of membranes (SROM) and 173 women with artificial rupture of membranes (AROM). The need for oxytocin was higher in both primi- and multigravidae in the AROM group (37.5% and 38.8%, respectively) than the SROM group (24.7% and 18.9%, respectively), but this association reached statistical significance only among multigravidae. Also higher in the AROM group than the SROM group, but not significantly, were the rates of instrumental delivery and emergency cesarean section. Compared with primigravid AROM women, a significantly larger number of primigravid AROM women had abnormal auscultated fetal heart rates and cardiotopographic patterns. The appearance of meconium in liquor and the occurrence of low Apgar scores were similar in both groups. There were no clinical maternal or neonatal infections, but the intrauterine sites showed evidence of inflammation soon after membrane rupture. 36.1% of women in the SROM group and 24.0% of those in the AROM group whose cord and membranes were evaluated had histologic evidence of inflammation. Choreoamnionitis and funisitis were slightly more common in the AROM group. The potential for infection at intrauterine sites had no linear relationship to the mean membrane rupture-delivery interval or the number of vaginal examinations.

    Background Spontaneous rupture of the spleen is an uncommon dramatic abdominal emergency that requires immediate diagnosis and prompt surgical treatment to ensure the patients survival. Infections have been cited in most cases involving splenic rupture but are rare in hematological malignancies despite frequent involvement of the spleen. Methods and Materials We present a case of a splenic rupture caused by infiltration of B-cell lymphoma. A 43 year old gentleman presented with a 1 day h/o left upper quadrant pain; nausea and vomiting for 2 days with associated dizziness and anorexia. The CT showed abnormal spleen 20 × 11 cm with free fluid in the abdomen and enlarged retroperitoneal LNs. The patient underwent a splenectomy after initial resuscitation and the operative finding was that of a massively enlarged spleen with areas of tumor extruding through the splenic capsule. Result and conclusion Although the spleen is often involved in hematological malignancies, splenic rupture is an infrequent occurrence. In a recent literature review 136 cases were of splenic rupture secondary to hematological malignancy were identified. Acute leukemia and non Hodgkin lymphoma were the frequent causes followed by chronic myelogeneous leukemia. Male sex, adulthood, severe splenomegaly and cytoreductive chemotherapy were factors more often associated with splenic rupture. Emergency splenectomy remains the cornerstone treatment for splenic rupture. We present a case report of a "spontaneous splenic rupture" and discuss the presentation, etiology and treatment options along with discussion of relevant literature PMID:17129392

    Aggressive natural killer cell leukemia/lymphoma (ANKL) is a rare aggressive form of NK-cell neoplasm. We report an uncommon case of 36-year-old male who showed jaundice and spontaneous splenic rupture. The diagnosis was established by the biopsy of liver and spleen. The monomorphous medium-size neoplastic cells infiltrated into portal areas and sinus of liver as well as the cords and sinus of the spleen. Necrosis, mitotic figures and significant apoptosis could be seen easily. These neoplastic cells demonstrated a typical immunophenotype of CD3ε+, CD56+, CD16+, Granzyme B+, TIA-1+. T-cell receptor γ (TCR-γ) gene rearrangement analysis showed germline configuration and the result of in situ hybridization for Epstein-Barr virus-encoded RNA (EBER-ISH) was positive. The patient has undergone an aggressive clinical course and died of multi-organ function failure 14 days later after admission. To the best of our knowledge, this is the first case of ANKL with spontaneous splenic rupture, and we should pay more attention to recognize it.

    We reported 3 elderly patients with right pneumothorax caused by ruptured paravertebral gourdshaped bullae. Two patients showed the characteristic symptom of air leakage of this type of pneumothorax, which decreased in the supine position, but increased in the sitting position. Chest computed tomography imaging showed bullae spreading in the space of the azygoesophageal recess. All patients underwent video-assisted thoracic surgery (VATS), and 2 patients underwent mini-thoracotomy because of adhesion and pyothorax. Ruptured bullae with stalks were found at the mediastinal sides of their right lower lobes in all patients. Bullectomy using an endoscopic stapler or ligation at the bulla root was performed easily and safely. The right pneumothorax caused by ruptured paravertebral gourd-shaped bulla was considered to be a good indication for the VATS due to the unique shape of the bulla, which has a stalk at its root.

  1. A grid-doubling finite-element technique for calculating dynamic three-dimensional spontaneous rupture on an earthquake fault

    2009-01-01

    We present a new finite-element technique for calculating dynamic 3-D spontaneous rupture on an earthquake fault, which can reduce the required computational resources by a factor of six or more, without loss of accuracy. The grid-doubling technique employs small cells in a thin layer surrounding the fault. The remainder of the modelling volume is filled with larger cells, typically two or four times as large as the small cells. In the resulting non-conforming mesh, an interpolation method is used to join the thin layer of smaller cells to the volume of larger cells. Grid-doubling is effective because spontaneous rupture calculations typically require higher spatial resolution on and near the fault than elsewhere in the model volume. The technique can be applied to non-planar faults by morphing, or smoothly distorting, the entire mesh to produce the desired 3-D fault geometry. Using our FaultMod finite-element software, we have tested grid-doubling with both slip-weakening and rate-and-state friction laws, by running the SCEC/ USGS 3-D dynamic rupture benchmark problems. We have also applied it to a model of the Hayward fault, Northern California, which uses realistic fault geometry and rock properties. FaultMod implements fault slip using common nodes, which represent motion common to both sides of the fault, and differential nodes, which represent motion of one side of the fault relative to the other side. We describe how to modify the traction-at-split-nodes method to work with common and differential nodes, using an implicit time stepping algorithm. ?? Journal compilation ?? 2009 RAS.

    To assess the rates and characteristics of women with complete uterine rupture, abnormally invasive placenta, peripartum hysterectomy, and severe blood loss at delivery in the Nordic countries. Prospective, Nordic collaboration. The Nordic Obstetric Surveillance Study (NOSS) collected cases of severe obstetric complications in the Nordic countries from April 2009 to August 2012. Cases were reported by clinicians at the Nordic maternity units and retrieved from medical birth registers, hospital discharge registers, and transfusion databases by using International Classification of Diseases, 10th revision codes on diagnoses and the Nordic Medico-Statistical Committee Classification of Surgical Procedure codes. Rates of the studied complications and possible risk factors among parturients in the Nordic countries. The studied complications were reported in 1019 instances among 605 362 deliveries during the study period. The reported rate of severe blood loss at delivery was 11.6/10 000 deliveries, complete uterine rupture was 5.6/10 000 deliveries, abnormally invasive placenta was 4.6/10 000 deliveries, and peripartum hysterectomy was 3.5/10 000 deliveries. Of the women, 25% had two or more complications. Women with complications were more often >35 years old, overweight, with a higher parity, and a history of cesarean delivery compared with the total population. The studied obstetric complications are rare. Uniform definitions and valid reporting are essential for international comparisons. The main risk factors include previous cesarean section. The detailed information collected in the NOSS database provides a basis for epidemiologic studies, audits, and educational activities. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

  3. Delivery of a baby with severe combined immunodeficiency at 31 weeks gestation following an extreme preterm prelabour spontaneous rupture of the membranes: a case report

    PubMed Central

    2009-01-01

    Introduction If left untreated, severe combined immunodeficiency can lead to an acute susceptibility to infection. The intrauterine environment is sterile until the amniotic membranes rupture. The vaginal flora then ascends into the genital tract, thus increasing the risk of chorioamnionitis. An extremely premature and prolonged membrane rupture is associated with a dismal prognosis for an immunocompetent preterm fetus. There are no case reports to date that detail the outcome of an immunocompromised preterm baby following prolonged rupture of membranes. Case presentation We present the case of a 32-year-old Indian woman who delivered a 31-week gestational baby who had a severe combined immunodeficiency following premature prelabour prolonged rupture of the membranes at the 14th week of gestation. Conclusion Extreme preterm prelabour spontaneous rupture of membranes in an underlying condition of severe combined immunodeficiency does not necessarily lead to an unfavourable outcome.

    Abstract Introduction: The predictive value of spiral artery flow Doppler measurements of a subsequent early miscarriage in first trimester pregnancy is explored here. Objective: The aim of this study is to determine uterine and spiral artery blood flow changes in first trimester subsequent miscarriages and correlate within the mechanisms of the Doppler indicies. Study design: The uterine artery and spiral artery pulsatility and resistance indexes, systolic and diastolic ratios, acceleration times, and blood flow of both the right and left uterine arteries were obtained by trans vaginal color Doppler ultrasonography in consecutive viable pregnancies between 5 and 12 gestational week. Women were subsequently classified as having continuing pregnancies or pregnancy loss before 20 weeks gestation. To predict subsequent pregnancy loss, Doppler findings were adjusted for maternal age, history of previous abortion, presence of subchorionic hematoma, embryonic bradycardia, and gestational age by means of multivariate logistic regression analysis. The cut‐off values are used for the ROC curve. Results: Twenty‐five pregnancies (11.7%) were spontaneously aborted before 20 weeks of gestational age. In 29 (13.6%) cases there were previously abortion history, 30 (14%) had bradycardia, and 37 (17.3%) had subchoronic hematoma. Regarding the parameters of uterine and spiral artery pulsatility and resistive index, acceleration time, systolic/diastolic ratios and blood flows, only uterine artery S/D low values were significantly associated with pregnancy loss in the multivariate logistic regression analysis (P = 0.0001,95% CI: 4.968–55.675). Conclusion: The uterine artery systolic/diastolic ratios have a predictive value for early pregnancy loss and seem to be useful as a marker. On the other hand, spiral artery changes could be so local that they cannot be determined by the parameters of spectral Doppler techniques. This suggests that uterine vascular bed alterations should

    Segmental arterial mediolysis (SAM) is a non-arteriosclerotic, non-inflammatory arteriopathy characterised by dissecting aneurysms and most commonly found in abdominal arteries. A rupture of a visceral artery aneurysm is generally associated with high mortality. We present the case of a 57-year-old woman with a rupture of an intrahepatic aneurysm that led to intra-abdominal haemorrhage. The patient was surgically treated by evacuating the abdominal haematoma and ligature of the right hepatic artery. Histology of the right hepatic artery revealed the diagnosis of SAM. Six months postoperatively, the patient was in excellent physical condition with normal liver function and arterial blood flow of the right hepatic sections over collateral circulation.

    Bilateral rupture of the patellar tendon is a very rare injury. It occurs in association with chronic systemic diseases or corticosteroid medications. We report a case of a 13-year-old child with Ehlers-Danlos syndrome presenting a bilateral patellar tendon disruption of proximal insertion that occurred with a trivial trauma. Surgical management consisting in tendon repair with a suture anchor technique protected temporarily with a cerclage wiring gives a good outcome.

    Background and objectives Compare the outcomes of three groups of patients with T4 hepatocellular carcinoma (HCC): tumor rupture with shock (RS group), tumor rupture without shock (R group), and no tumor rupture (NR group). Materials and Methods We retrospectively reviewed 221 patients with T4 HCC from 2010 to 2012. The clinical background and prognosis were analyzed. Results Overall in‐hospital mortality rate was 18.1%; overall median survival time was 4 months. The NR group were more likely to have multiple and infiltrative tumors (P < 0.001). Relative to the NR group, the R + RS group had better survival rates at 6 months (49.2% vs. 32.2%), 1 year (35.3% vs. 21.0%), 3 years (22.5% vs. 11.0%), and 5 years (17.7% vs. 5.5%) (P = 0.010). Patients in the RS group had a higher in‐hospital mortality rate, but significantly better long‐term survival than the NR and R group (P < 0.001). Multivariate analysis indicated that Child‐Pugh class B or C, presence of portal venous thrombosis, and absence of shock were significantly associated with poor survival. Conclusion Patients with tumor rupture and shock had worse in‐hospital survival. However, patients without decompensated liver cirrhosis and portal venous thrombosis, and eligible for curative treatment had favorable long‐term outcome. J. Surg.

    Abstract Rupture of jejunal artery aneurysm is a very rare event resulting in life-threatening hemorrhage in Behcet disease (BD). We report a case of ruptured jejunal artery aneurysm in a 35-year-old patient with BD. The patient had a 1-year history of intermittent abdominal pain caused by superior mesenteric artery aneurysm with thrombosis. Anticoagulation treatment showed a good response. Past surgical history included stenting for aortic pseudoaneurysm. On admission, the patient underwent an urgent operation due to sudden hemorrhagic shock. Resection was performed for jejunal artery aneurysm and partial ischemia of intestine. The patient was diagnosed with BD, based on a history of recurrent oral and skin lesions over the past 6 years. Treatment with anti-inflammatory medications showed a good response during the 8-month follow-up. An increased awareness of BD and its vascular complications is essential. Aneurysms in BD involving jejunal artery are rare, neglected and require proper management to prevent rupture and death. To our knowledge, this is the first reported case of jejunal artery aneurysm caused by BD. PMID:26559278

    Aneurysms of the superior mesenteric artery branches are rarely reported, even among them colic artery aneurysms are seldom. We report a case of 78-year-old male with ruptured dissecting aneurysm of middle colic artery. The patient complained abdominal pain and nausea during hospital stay for renal stone. The patient suddenly developed severe abdominal pain, leading to shock. He underwent emergency surgery under a preoperative diagnosis of intraperitoneal hemorrhage. At exploratory laparotomy, a large hematoma involving the mesentery root of the transverse colon was associated with a ruptured aneurysm measuring 15 x 10 mm in size, which was located to the mid-portion of middle colic artery. Right-hemicolectomy was carried out because of ischemic changes in the ascending colon. Histological examination demonstrated a ruptured dissecting aneurysm of the middle colic artery approximately 5 cm in length, associated with destruction of the tunica interna and media. The aneurysm was thought to result from idiopathic segmental arterial mediolysis, because no definitive evidence of atherosclerosis or arteritis was observed.

    1-2% of all twin pregnancies are complicated by premature contractions, leading to premature rupture of membranes before 26 weeks of pregnancy. In this situation, a decision is required to either actively induce premature delivery or to initiate expectant management. Maternal and fetal risks regarding perinatal mortality and morbidity and the benefits of pregnancy prolongation have to be weighted against each other. We present delayed deliveries of two I-Parae with dichorionic twin pregnancies, achieved by in vitro fertilisation. In both cases, spontaneous membrane rupture and miscarriage of the leading fetus occurred prior to 20 gestational weeks. As signs of infection were missing initially, we adopted a conservative, expectant management. In both cases, the pregnancies could be prolonged to more than 30 weeks' gestation. In the absence of additional risk factors, expectant, conservative management of multiple pregnancies after loss of one fetus can lead to pregnancy prolongation of 91 and 96 days, respectively. The gained gestational age of the remaining fetus and the healthy mother-child pairs are discussed under perinatal, economical and psychological aspects.

  12. Quantification of Ground Motion Reductions by Fault Zone Plasticity with 3D Spontaneous Rupture Simulations

    We explore the effects of fault zone nonlinearity on peak ground velocities (PGVs) by simulating a suite of surface rupturing earthquakes in a visco-plastic medium. Our simulations, performed with the AWP-ODC 3D finite difference code, cover magnitudes from 6.5 to 8.0, with several realizations of the stochastic stress drop for a given magnitude. We test three different models of rock strength, with friction angles and cohesions based on criteria which are frequently applied to fractured rock masses in civil engineering and mining. We use a minimum shear-wave velocity of 500 m/s and a maximum frequency of 1 Hz. In rupture scenarios with average stress drop (~3.5 MPa), plastic yielding reduces near-fault PGVs by 15 to 30% in pre-fractured, low-strength rock, but less than 1% in massive, high quality rock. These reductions are almost insensitive to the scenario earthquake magnitude. In the case of high stress drop (~7 MPa), however, plasticity reduces near-fault PGVs by 38 to 45% in rocks of low strength and by 5 to 15% in rocks of high strength. Because plasticity reduces slip rates and static slip near the surface, these effects can partially be captured by defining a shallow velocity-strengthening layer. We also perform a dynamic nonlinear simulation of a high stress drop M 7.8 earthquake rupturing the southern San Andreas fault along 250 km from Indio to Lake Hughes. With respect to the viscoelastic solution (a), nonlinearity in the fault damage zone and in near-surface deposits would reduce long-period (> 1 s) peak ground velocities in the Los Angeles basin by 15-50% (b), depending on the strength of crustal rocks and shallow sediments. These simulation results suggest that nonlinear effects may be relevant even at long periods, especially for earthquakes with high stress drop.

    Dermoid cysts are rare benign congenital tumors comprising 1.1 % of the spinal tumors, with lumbosacral region and cauda equina being the common sites. Many cranial cases with spillage of cyst contents into the subarachnoid space have been reported. We report an extremely unusual case of symptomatic spinal dermoid cyst that ruptured into the syrinx cavity. The gold standard treatment is complete resection of both cyst wall and content in dermoid cysts. However, there is no consensus for the treatment of the syrinx cavity. Observation of similar cases would give us more information about treatment options and the progression of these lesions.

    We discussed the case of a 14-year-old patient with acute onset of psychiatric symptoms for two months who had been examined and different antipsychotic drugs had been prescribed by several psychiatrists without any neuroradiological imaging. Because of unresponsiveness to the antipsychotic drugs, computed tomography and magnetic resonance imaging were performed which revealed a ruptured intracranial dermoid cyst. The patient underwent surgery and antipsychotic medications were withdrawn in short time. The emphasis of this case is that intracranial lesions can present with neuropsychiatric symptoms and findings only without any neurological deficit or signs.

    A 7-month-old male cross breed dog was presented with hyperextensible skin and atrophic scarring. A diagnosis of Ehlers-Danlos syndrome was made based on clinical signs, histopathology and electron microscopy. Two weeks after presentation, the dog died suddenly. Post-mortem examination revealed haemothorax and rupture of the left subclavian artery. Histological findings, including Goldner's modified Masson's trichrome staining and transmission electron microscopy of the subclavian artery, revealed abnormalities in the structure and arrangement of collagen fibrils, suggesting that the defective collagen formation extended to the vasculature. To the authors' knowledge, this is the first report of Ehlers-Danlos syndrome with vascular involvement in animals.

    Babesiosis is a zoonotic disease transmitted by the Ixodes tick species. Infection often results in sub-clinical manifestations; however, patients with this disease can become critically ill. Splenic rupture has been a previously reported complication of babesiosis, but treatment has always led to splenectomy. Asplenia places a patient at greater risk for overwhelming post-splenectomy infection from encapsulated bacteria, Lyme disease, Ehrlichia as well as Babesia microti. Therefore, avoiding splenectomy in these patients must be considered by the physician; particularly, if the patient is at risk for re-infection by living in an endemic area. A 54 year-old male from the northeast United States presented with left upper quadrant abdominal pain associated with fever, chills, night sweats and nausea. A full evaluation revealed active infection with Babesia microti and multiple splenic lacerations. This patient was successfully treated with appropriate pharmacological therapy and non-operative observation for the splenic injury. Patients diagnosed with Babesia microti infection are becoming more common, especially in endemic areas. Although clinical manifestations are usually minimal, this infection can present with significant injuries leading to critical illness. We present the successful non-operative treatment of a patient with splenic rupture due to babesiosis infection.

    Intra-abdominal hemorrhage caused by omental artery rupture is a rare condition. There are few reports on the treatment of omental artery rupture with only transcatheter arterial embolization (TAE). A 27-year-old man presented to our emergency room with upper abdominal pain that suddenly occurred during sleep. Abdominal computed tomography (CT) revealed fluid collection in the peritoneal cavity and a left subphrenic hematoma with extravasation. Celiac angiography revealed extravasation from the omental artery, which arose from the proximal left gastroepiploic artery. A microcatheter was advanced into the left gastroepiploic artery and around the culprit artery bifurcation, which was embolized by inserting coils. The postoperative course was uneventful without worsening of anemia or abdominal symptoms. The patient was discharged after the absence of extravasation was confirmed by contrast-enhanced CT. Although surgical therapy has often been performed for omental bleeding, TAE, which is less invasive and has the advantage of simultaneous diagnosis and treatment, should be attempted as the first-choice therapy.

    Background: Spontaneous intraventricular rupture of brain abscess (IVROBA) is a dreaded complication of pyogenic brain abscess (PBA) and is associated with very high mortality. We discuss the clinical, radiological, and therapeutic aspects associated with this potentially fatal complication of PBAs. Case Descriptions: Three cases of spontaneous IVROBA presenting to our institute over a period of 6 months were reviewed with respect to their clinical and radiological presentation, their therapeutic plan, and neurological outcome. Individualized approach to our patients with IVROBA with abscess drainage/excision, intrathecal and intravenous antibiotic therapy, cerebrospinal fluid (CSF) diversion (if under high pressure), and close monitoring of clinical status, CSF reports, and computed tomography (CT) scan findings enabled us to achieve good neurological outcome in two patients presenting in conscious state; however, one patient presenting in poor neurological status succumbed to IVROBA due to fulminant septic arteritis. Conclusion: In the present neurosurgical era, IVROBA is rarely encountered; however when it occurs, patient outcome is adversely affected. Early detection and prompt aggressive management, as seen in our short series, can give the patient a fighting chance and significantly improve the neurological outcome. PMID:28031988

She was treated with coiling of the largest paraclinoid aneurysm and placement of a flow diverting pipeline embolization device that covered all internal carotid artery (ICA) aneurysms. A follow-up angiogram at 6 months showed remodeling of the ICA with complete obliteration of all treated aneurysms. A distant, untreated, right frontal M2 aneurysm regressed spontaneously, after the flow was diverted away from it with the stent. The literature is reviewed, and potential pathophysiological mechanisms leading to aneurysm regression are discussed.

    Spontaneous pneumothorax is rarely reported in the cat. This case report describes the use of computed tomography (CT) to diagnose pulmonary bullae in an adult cat with recurrent spontaneous pneumothorax. A large bulla in the right middle lung lobe and several blebs in other lobes were identified by CT. Partial lobectomy of the right middle and right and left cranial lung lobes was successfully performed to remove the affected portions of lung. Histopathological examination suggested bronchopulmonary dysplasia (BPD) as the underlying cause for development of the pulmonary bulla. This is the first case report in the veterinary literature describing the use of CT to identify pulmonary bullae in the cat with BPD as a possible underlying cause.

    The objective of this study was to examine if patients with "early rupture of membranes (ROM)" after spontaneous onset of labor are at increased risk of cesarean section. The rate of cesarean section was examined in 447 term singleton nulliparas who were admitted after the spontaneous onset of labor. The cases were divided into 2 groups: (1) "early ROM", defined as ROM at a cervical dilatation <4 cm (n=109); and (2) "late ROM", ROM at a cervical dilatation >or=4 cm (n=338). (1) "Early ROM" occurred in 24.4% of the cases and the overall cesarean section rate was 5.6%; (2) there were no significant differences in the clinical characteristics including prepregnancy BMI, proportion of complicated pregnancies, total duration of labor, proportion of regional anesthesia, gestational age at delivery, and birthweight between the two groups of cases. However gravidas with "early ROM" were of advanced maternal age and had less cervical dilation on admission, shorter duration of 1st stage of labor, and more frequent use of oxytocin augmentation; (3) patients with "early ROM" had a threefold higher rate (11.9% vs. 3.6%) of cesarean section and a fourfold higher rate (11.9% vs. 3.0%) of cesarean section due to failure of progress than did those with "late ROM" (p<0.005 for each); (3) 92% (23/25) of cesarean sections were performed due to failure to progress; and (4) there was no significant difference in the rate of histologic chorioamnionitis between the two groups of cases. "Early ROM" after the spontaneous onset of labor is a risk factor for cesarean section in term singleton nulliparas. 2009 Elsevier Ireland Ltd. All rights reserved.

    Introduction Herein we present a rare case of pontaneous rupture of a giant renal angiomyolipoma (AML), with symptoms of hypovolemic shock (Wunderlich’s syndrome), which was managed by urgent total nephrectomy. Presentation of case A 53 year old female was transferred to the emergency room with progressive acute painful swelling of the left lateral abdominal area, duration of 5 h. An emergent ultrasonic examination, revealed a heterogeneous—solid mass with maximum diameter of 23 cm, with probable origin from the left kidney. Due to worsening of the clinical status (hypovolemic shock), loss of consciousness and acute drop of haematocrit level to 17.8%, the patient was urgently intubated in the emergency room and transferred to the operating theater. A giant haemorrhagic mass was found originating from the left kidney, which removed en-block with the left kidney. The patient was transferred to the intensive care unit. Her recovery was uneventful. The histopathologic examination revealed a giant renal angiomyolipoma (25 × 18 × 8 cm) with extensive bleeding. Discussion Enlarged renal AMLs can rupture. This can be sudden and painful with manifestations of hypovolemic shock. The management of AMLs has been correlated with symptoms. Patients with life-threatening retroperitoneal haemorrhage, require urgent exploration as retroperitoneal bleeding can lead to severe complications, increasing morbidity. Conclusion In case of giant angiomyolipoma with intratumoral haemorrhage, and symptoms of Wunderlich’s syndrome, partial or total nephrectomy is a good treatment option in order to save the patient’s life.

    Experimental stick-slips are commonly envisioned as laboratory analogues of the spontaneous faults slip during natural earthquakes (Brace & Byerlee, 1966). However, typical experimental stick-slips are tiny events of slip distances up to a few tens of microns. To close the gap between such events and natural earthquakes, we develop a new method that produces spontaneous stick-slips with large displacements on our rotary shear apparatus (Reches & Lockner, 2010). In this method, the controlling program continuously calculates the real-time power-density (PD = slip-velocity times shear stress) of the experimental fault. Then, a feedback loop modifies the slip-velocity to match the real-time PD with the requested PD. In this method, the stick-slips occur spontaneously while slip velocity and duration are not controlled by the operator. We present a series of tens stick-slip events along granite and diorite experimental faults with 0.0001-1.3 m of total slip and slip-velocity up to 0.45 m/s. Depending on the magnitude of the requested PD, we recognized three types of events: (1) Stick-slips with a nucleation slip that initiates ~0.1 sec before the main slip which is characterized by temporal increase of shear stress, normal stress, and fault dilation; (2) Events resembling slip-pulse behavior of abrupt acceleration and intense dynamic weakening and subsequent strength recovery; and (3) Small, creep events during quasi-continuous, low- velocity slip with tiny changes of stress and dilation. The energy-displacement catalog of types (1) and (2) events shows good agreement with previous slip-pulse experiments and natural earthquakes (Chang et al., 2012). The present experiments indicate that power-density control is a promising experimental approach for earthquake simulations.

    Previous studies have shown that plastic yielding in crustal rocks in the fault zone may impose a physical limit to extreme ground motions. We explore the effects of fault-zone non-linearity on peak ground velocities (PGVs) by simulating a suite of surface-rupturing strike-slip earthquakes in a medium governed by Drucker-Prager plasticity using the AWP-ODC finite-difference code. Our simulations cover magnitudes ranging from 6.5 to 8.0, three different rock strength models, and average stress drops of 3.5 and 7.0 MPa, with a maximum frequency of 1 Hz and a minimum shear-wave velocity of 500 m/s. Friction angles and cohesions in our rock models are based on strength criteria which are frequently used for fractured rock masses in civil and mining engineering. For an average stress drop of 3.5 MPa, plastic yielding reduces near-fault PGVs by 15-30% in pre-fractured, low strength rock, but less than 1% in massive, high-quality rock. These reductions are almost insensitive to magnitude. If the stress drop is doubled, plasticity reduces near-fault PGVs by 38-45% and 5-15% in rocks of low and high strength, respectively. Because non-linearity reduces slip rates and static slip near the surface, plasticity acts in addition to, and may partially be emulated by, a shallow velocity-strengthening layer. The effects of plasticity are exacerbated if a fault damage zone with reduced shear-wave velocities and reduced rock strength is present. In the linear case, fault-zone trapped waves result in higher near-surface peak slip rates and ground velocities compared to simulations without a low-velocity zone. These amplifications are balanced out by fault-zone plasticity if rocks in the damage zone exhibit low-to-moderate strength throughout the depth extent of the low-velocity zone (˜ 5 km). We also perform dynamic non-linear simulations of a high stress drop (8 MPa) M 7.8 earthquake rupturing the southern San Andreas fault along 250 km from Indio to Lake Hughes. Non-linearity in

Here, we are reporting a rare case of peritonitis with a pneumoperitoneum in an elderly female, which was caused by a spontaneous perforation of pyometra. A 74-years old postmenopausal female with uncontrolled diabetes mellitus was admitted to surgical emergency with signs of diffuse peritonitis and she was in shock. After resuscitation, an emergency laparotomy was performed because of suspicion of a hollow viscous perforation with peritonitis. At laparotomy, about 2000ml of purulent fluid was found to be present in peritoneal cavity, while alimentary tract was intact. A rent with a diameter of 0.8 cm was found on fundus of uterus. A total abdominal hysterectomy with a bilateral salphingo oophorectomy was performed. Patient got discharged on 12(th) post-operative day without major complications. Histopathological studies revealed endometritis and myometritis, with no evidence of malignancy.

    The purpose of this study was to examine the relationship between rupture of membranes, labor, and microbial invasion of the amniotic cavity and amniotic fluid concentrations of eicosanoids in patients with spontaneous rupture of membranes at term. Amniotic fluid was retrieved by transabdominal amniocentesis from patients with rupture of membranes and patients with intact membranes at term. Studies to determine the microbial state of the amniotic cavity included culture for bacteria and mycoplasmas, Gram stain, amniotic fluid white blood cell count, and Limulus amebocyte lysate. Eicosanoids (prostaglandin E2, prostaglandin F2 alpha and its stable metabolite, 6-keto-prostaglandin F1 alpha, and thromboxane B2) were determined with sensitive and specific radioimmunoassays validated for human amniotic fluid. Statistical inference was conducted with analysis of variance and linear contrast. (1) Spontaneous rupture of membranes at term was associated with a significant increase in amniotic fluid concentrations of all eicosanoids measured in this study except 6-keto-prostaglandin F1 alpha. (2) Early labor in patients with rupture of membranes was associated with a significant increase in the amniotic fluid concentration of all eicosanoids. (3) A significant increase in amniotic fluid eicosanoids in women with microbial invasion of the amniotic cavity could not be documented. Whereas preterm labor in the absence of microbial invasion of the amniotic cavity is not associated with a significant increase in amniotic fluid concentrations of prostaglandins, a clear increase was documented in women with early labor after spontaneous rupture of membranes. These observations suggest that there are fundamental differences in the biochemistry of term and preterm parturition.

    Introduction Ectopic pregnancy accounts for 1–2% of all pregnancies in the United States. The most common site of implantation for an ectopic pregnancy is the fallopian tube. We present the first case describing a recurrent ectopic pregnancy with a fetal heartbeat after ipsilateral salpingectomy that led to tubal rupture. Presentation of case The patient presented with abdominal pain approximately six weeks after her last menstrual period. Seven years prior to presentation, a laparoscopic partial right salpingectomy had been performed for a tubal ectopic pregnancy. Physical exam was significant for diffuse abdominal tenderness and guarding. Ultrasonography revealed a right tubal pregnancy with a fetal pole and a fetal heart rate that was calculated to be 108 beats per minute. Free fluid was also noted. 1.5 l of hemoperitoneum was subsequently evacuated and the right fallopian tube remnant with the ectopic pregnancy was removed. Pathology of the tubal remnant showed immature chorionic villi and fetal parts. Discussion The mechanism by which a recurrent ectopic pregnancy after ipsilateral salpingectomy occurs is unclear, but is theorized to be secondary to contralateral fertilization and/or tubal recanalization that may occur due to inadequate diathermy. Conclusion Physicians should be aware that ectopic pregnancies may not only occur repeatedly but may also present a typically. We recommend when performing a salpingectomy that efforts be undertaken to minimize the length of the tubal remnant and to assure adequate coagulation of tissue so as to reduce the risk of recurrence.

    A 7-month-old baby presented with a 4-day history of drowsiness and vomiting after a falling accident. Magnetic resonance imaging demonstrated diffuse subarachnoid hemorrhage, intraventricular hemorrhage, and variable stages of subdural hematoma in bilateral occipital and left temporal subdural spaces. A partially thrombosed aneurysm was noted in the right craniocervical junction. Ophthalmological examination revealed bilateral retinal petechial hemorrhages. Conventional cerebral angiography revealed a dissecting aneurysm in the right posterior inferior cerebellar artery (PICA). Endovascular embolization was suggested, but the family refused. After conservative treatment, follow-up MRI revealed that the PICA aneurysm had remodeled and ultimately disappeared completely at the 10th month. This case illustrates the relatively plastic nature of intracranial aneurysms in pediatric patients. More studies are necessary to clarify the natural history of spontaneously thrombosed aneurysms to assist in their overall management.

In our case, the uterine scar is discovered to be ruptured during the postpartum period. The exact cause and time of uterine rupture is difficult to ascertain in this case, yet manual palpation of the uterine scar did not aid in the eventual diagnosis.

    A case of spontaneous rupture of a liver cell adenoma is reported in a female transexual treated with methyltestosterone 150 mg daily for 7 years. Emergency right hepatic lobectomy was performed successfully. Histology showed peliosis hepatis also. Emergency resection of a liver cell adenoma has been reported in a young woman taking oral contraceptives, and an elective resection in another female transexual treated with methyltestosterone. However, to the best of our knowledge this is the first case of emergency resection of a spontaneously ruptured liver cell adenoma in a transexual treated with long term methyltestosterone. Since there are numerous other patients similarly treated, it may be expected that this complication will be seen again.

    We report a case of a spontaneous rupture of a right subclavian aneurysm in a 15 year-old patient. This ruptured aneurysm was successfully treated in an endovascular manner by placing a covered stent-graft in the right subclavian artery via right brachial access. Subsequent work-up by skin biopsy and fibroblast culture and by DNA-screening revealed the diagnosis of Ehlers Danlos type IV. Meanwhile, the patient developed twice a spontaneous pneumothorax, treated with thoracoscopic pleurodesis. This article provides a clear overview of the clinical and genetic characteristics of a case of Ehlers Danlos type IV and illustrates the importance of avoiding surgery in patients with connective tissue disease because of the high risk of perioperative complications.

    To determine the measures to prevent spontaneous preterm birth (excluding preterm premature rupture of membranes)and its consequences. The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated to a decrease of prematurity (level of evidence [LE] 1). This is therefore recommended (grade A). Routine screening and treatment of vaginal bacteriosis in general population is not recommended (grade A). Asymptomatic women with single pregnancy without history of preterm delivery and a short cervix between 16 and 24 weeks is the only population in which vaginal progesterone is recommended (grade B). A history-indicated cerclage is not recommended in case of only past history of conisation (grade C), uterine malformation (Professional consensus), isolated history of pretem delivery (grade B) or twin pregnancies in primary (grade B) or secondary (grade C) prevention of preterm birth. A history-indicated cerclage is recommended for single pregnancy with a history of at least 3 late miscarriages or preterm deliveries (grade A).). In case of past history of a single pregnancy delivery before 34 weeks gestation (WG), ultrasound cervical length screening is recommended between 16 and 22 WG in order to propose a cerclage in case of length<25mm before 24 WG (grade C). Cervical pessary is not recommended for the prevention of preterm birth in a general population of asymptomatic women with a twin pregnancy (grade A) and in populations of asymptomatic women with a short cervix (Professional consensus).

    Artificial procedures are used to initiate spontaneous rupture on faults with the linear slip-weakening (LSW) friction law. Probably the most frequent technique is the stress asperity. It is important to minimize effects of the artificial initialization on the phase of the spontaneous rupture propagation. The effects may strongly depend on the geometry and size of the asperity, spatial distribution of the stress in and around the asperity, and a maximum stress-overshoot value. A square initialization zone with the stress discontinuously falling down at the asperity border to the level of the initial stress has been frequently applied (e.g., in the SCEC verification exercise). Galis et al. (2010) and Bizzarri (2010) independently introduced the elliptical asperity with a smooth spatial stress distribution in and around the asperity. In both papers the width of smoothing/tapering zone was only ad-hoc defined. Numerical simulations indicate that the ADER-DG method can account for a discontinuous-stress initialization more accurately than the FE method. Considering the ADER-DG solution a reference we performed numerical simulations in order to define the width of the smoothing/tapering zone to be used in the FE and FD-FE hybrid methods for spontaneous rupture propagation. We considered different sizes of initialization zone, different shapes of the initialization zone (square, circle, ellipse), different spatial distributions of stress (smooth, discontinuous), and different stress-overshoot values to investigate conditions of the spontaneous rupture propagation. We compare our numerical results with the 2D and 3D estimates by Andrews (1976a,b), Day (1982), Campillo & Ionescu (1997), Favreau at al. (1999) and Uenishi & Rice (2003, 2004). Results of our study may help modelers to better setup the initialization zone in order to avoid, e.g., a too large initialization zone and reduce numerical artifacts.

    Spontaneous rupture of hepatocellular carcinoma (HCC) is a life-threatening complication and its prognosis is significantly poor because of the high recurrence rate after initial hepatectomy. Resection of isolated extrahepatic metastasis of HCC has been advocated to obtain a possibility of long-term survival. However, it is a challenge for clinicians to detect implantation metastasis of spontaneously ruptured HCC. Accurate re-staging plays the most important role in making a decision on isolated metastasis resection. 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) is useful in detecting intra-abdominal implantation metastasis from a variety of malignancies and shows superior accuracy to conventional imaging modalities in determining the location of metastasis. We present one patient with a new isolated pelvic implantation metastasis detected by 18F-FDG PET/CT and pathologically confirmed by PET/CT-guided percutaneous biopsy, who had a history of resection of spontaneously ruptured HCC two years ago. The patient’s condition was stable at the 6-mo follow-up after resection of the isolated pelvic metastasis. PMID:27895412

    In women with preterm premature rupture of the membranes (PPROM), increased oxidative stress may accelerate premature cellular senescence, senescence-associated inflammation and proteolysis, which may predispose them to rupture. We demonstrate mechanistic differences between preterm birth (PTB) and PPROM by revealing differences in fetal membrane redox status, oxidative stress-induced damage, distinct signaling pathways and senescence activation. Oxidative stress-associated fetal membrane damage and cell cycle arrest determine adverse pregnancy outcomes, such as spontaneous PTB and PPROM. Fetal membranes and amniotic fluid samples were collected from women with PTB and PPROM. Molecular, biochemical and histologic markers were used to document differences in oxidative stress and antioxidant enzyme status, DNA damage, secondary signaling activation by Ras-GTPase and mitogen-activated protein kinases, and activation of senescence between membranes from the two groups. Oxidative stress was higher and antioxidant enzymes were lower in PPROM compared with PTB. PTB membranes had minimal DNA damage and showed activation of Ras-GTPase and ERK/JNK signaling pathway with minimal signs of senescence. PPROM had higher numbers of cells with DNA damage, prosenescence stress kinase (p38 MAPK) activation and signs of senescence. Samples were obtained retrospectively after delivery. The markers of senescence that we tested are specific but are not sufficient to confirm senescence as the pathology in PPROM. Oxidative stress-induced DNA damage and senescence are characteristics of fetal membranes from PPROM, compared with PTB with intact membranes. PTB and PPROM arise from distinct pathophysiologic pathways. Oxidative stress and oxidative stress-induced cellular damages are likely determinants of the mechanistic signaling pathways and phenotypic outcome.

    Women with chronic hypertension are at increased risk of maternal and fetal morbidity and mortality. We have previously characterized the stroke-prone spontaneously hypertensive rat (SHRSP) as a model of deficient uterine artery function and adverse pregnancy outcome compared with the control Wistar–Kyoto. The activation of the immune system plays a role in hypertension and adverse pregnancy outcome. Therefore, we investigated the role of tumor necrosis factor-α in the SHRSP phenotype in an intervention study using etanercept (0.8 mg/kg SC) at gestational days 0, 6, 12, and 18 in pregnant SHRSP compared with vehicle-treated controls (n=6). Etanercept treatment significantly lowered systolic blood pressure after gestational day 12 and increased litter size in SHRSP. At gestational day 18, etanercept improved the function of uterine arteries from pregnant SHRSP normalizing the contractile response and increasing endothelium-dependent relaxation, resulting in increased pregnancy-dependent diastolic blood flow in the uterine arteries. We identified that the source of excess tumor necrosis factor-α in the SHRSP was a pregnancy-dependent increase in peripheral and placental CD3– CD161+ natural killer cells. Etanercept treatment also had effects on placental CD161+ cells by reducing the expression of CD161 receptor, which was associated with a decrease in cytotoxic granzyme B expression. Etanercept treatment improves maternal blood pressure, pregnancy outcome, and uterine artery function in SHRSP by antagonizing signaling from excess tumor necrosis factor-α production and the reduction of granzyme B expression in CD161+ natural killer cells in SHRSP.

    This patient presented for surgery at the age of 32 years, 14 months after his initial complaint of metamorphopsia and visual loss in the right eye. Past tests demonstrated a whitish epiretinal membrane (ERM) with translucent stress lines over a thickened macula. Visual acuity was found on last presentation to be normal with minimal alteration on Amsler grid testing. A torn ERM was found in the center with left-over ERM temporally and rolled-over ERM nasally at the site of the epicenter with no posterior vitreous detachment. Visual recovery occurred gradually over several days 2 months prior to presentation apparently following heavy weight-lifting with a sensation of severe eye pressure. Sequential funduscopy and optical coherence tomography scans demonstrated the peeling of an ERM accompanied by normalization of foveal thickness. Valsalva maneuver had put excessive tension on ERM which tore in its center at the weakest line with gradual contraction of the ERM away from the fovea towards the peripapillary area. This is a new mechanism of self-separation of ERM induced by Valsalva. ERM in young subjects is subject to rupture and subsequent separation by tangential traction. There are three mechanisms for spontaneous separation of ERM: 1) posterior vitreous detachment with pulling of ERM by detaching vitreous (most common in adults); 2) the contracting forces of the immature ERM become stronger than its adhesions to the retina resulting in slow tangential traction on the edges of the ERM and gradual separation from the edges towards the center (remodeling common in youngsters); and 3) acute tearing of ERM at its weakest central point and retraction of part of the membrane towards the epicenter (current case report).

    There were 156 uterine ruptures collected out of 34,807 deliveries in the gynaecological and obstetrical department of the University Hospital of Averroes in Casablanca. This is a rate of 1 per 223 deliveries. The factors that predispose to this complication are low socio-economic status of the patients, multiparity and, above all, a scarred uterus. Surgical abnormalities of the pelvis and dystocia due to malpresentations and above all inappropriate manoeuvres which continue to be practised are all responsible for the condition. The rupture usually occurs in the lower segment. When the lesions are extensive the cervix and the bladder are most often damaged. Treatment should be as conservative as possible to maintain the woman's fertility but at the same time doing whatever is necessary for her.

    Disruption of the knee extensor mechanism is a serious disorder that requires prompt treatment. It often occurs in the form of a patellar tendon rupture. It may occur in association with systemic disease or after administration of corticosteroids or fluoroquinolones. These conditions can cause tendon weakness, and consequent ruptures usually require both repair and augmentation. This paper reports on repair and augmentation for treating patellar tendon rupture in patients with Ehlers-Danlos syndrome (EDS). We report a patellar tendon rupture in a 27-year-old man with EDS, which occurred in the midsubstance of the patella. As the patient has tendon weakness, extensive repair will increase the risk of patella baja, and the use of end-to-end suturing technique alone will not be enough to prevent a rupture recurring; however, augmentation could be used to address the tendon weakness. Repair of the rupture and augmentation with hamstring tendon was performed. One year after the surgery, the patient was able to move his knee joint without pain and had an active range of motion of 0° (passive 20°)-145°. He was able to perform a straight leg raise without an extension lag. Repair and augmentation with hamstring tendon was an effective treatment option for patellar tendon rupture in a patient with EDS.

    Both middle colic artery (MCA) aneurysm and spontaneous dissection of the superior mesenteric artery (SMA) are rare. We report the first case of concomitancy of both conditions, diagnosed by ultrasonography and CT angiography. A 56-year-old man with abrupt abdominal pain and hypovolemic shock was diagnosed initially with ruptured MCA aneurysm by color Doppler ultrasonography. Computed tomography and angiography confirmed MCA aneurysm and showed that it was arising from the false lumen of an SMA dissection and was probably associated with segmental arterial mediolysis. The MCA aneurysm was treated successfully by transcatheter coil embolization, and the SMA dissection was treated conservatively.

Spontaneous phasic contractions and [Ca2+]i were measured simultaneously in the longitudinal strips of female Sprague-Dawley rats late in their pregnancy (on day 18~20 of gestation: term=22 days). The expression of T-type Ca2+ channel mRNAs or protein levels was measured. Cumulative addition of low concentrations (<1 µM) of nifedipine, a L-type Ca2+ channel blocker, produced a decrease in the amplitude of the spontaneous Ca2+ transients and contractions with no significant change in frequency. The mRNAs and proteins encoding two subunits (α1G, α1H) of the T-type Ca2+ channels were expressed in longitudinal muscle layer of rat myometrium. Cumulative addition of mibefradil, NNC 55-0396 or nickel induced a concentration-dependent inhibition of the amplitude and frequency of the spontaneous Ca2+ transients and contractions. Mibefradil, NNC 55-0396 or nickel also attenuated the slope of rising phase of spontaneous Ca2+ transients consistent with the reduction of the frequency. It is concluded that T-type Ca2+ channels are expressed in the pregnant rat myometrium and may play a key role for the regulation of the frequency of spontaneous phasic contractions. PMID:19885043

    Coughing is the most efficient mechanism for clearing mucus and fluid secretions from the airways and its reflex can be suppressed by sleep. Spontaneous tracheal ruptures are believed to result from raised intratracheal pressure against a closed glottis, such as for severe coughing. This is the first reported case of tracheal rupture presented on morning awakening after bronchial mucous plug formation during the nighttime sleep because of an ineffective cough reflex. An otherwise healthy white 4-year-old child presented morning onset of dyspnea, chest pain and diffuse swelling of the neck. His history was significant only for nonsevere coughing episodes before his nighttime rest; the child's parents denied any recent fever, weight loss, pains, trauma, bronchial asthma, and sick contacts. A chest X-ray and computed tomography scan revealed pneumomediastinum, obstructive atelectasis of the lower lobe of his left lung, and a small tracheal laceration confirmed by an emergency bronchoscopy. After endoscopic removal of a mucous plug and secretions, the child's pulmonary gas exchange and respiratory rate improved, so our patient was managed conservatively. This report illustrates an unusual presentation of lung obstructive atelectasis due to a mucous plug manifested by tracheal rupture. This report also highlights the importance of the coughing reflex as one of several defensive mechanisms protecting the airways from the potentially damaging effects of aspirate and accumulated secretions.

    The spontaneous disappearance and reappearance of a ruptured cerebral aneurysm is generally assumed to be a rare phenomenon although the actual incidence is unknown. Among 39 consecutive cases of acute subarachnoid hemorrhage (SAH), 33 were studied by three-dimensional computed tomographic angiography (CTA) within 6 h after the onset of SAH, followed by digital subtraction angiography (DSA) within 24 h after the ictus. Of those patients, one, a 58-year-old woman, had a saccular aneurysm at the distal anterior cerebral artery; the aneurysm was clearly demonstrated by CTA 2.5 h after the SAH onset, but was not shown by a subsequent DSA performed 8.5 h after the ictus. A follow-up DSA detected the neck of aneurysm on day 11, and the whole aneurysm was visualized on day 19. The observations in this particular case suggest that the spontaneous disappearance of a ruptured cerebral aneurysm may occur during the ultra-early stage of SAH and that reappearance may follow during the next few weeks. The patient did not suffer complications such as vasospasm or systemic hypotension nor was she treated with antifibrinolytic agents. The aneurysmal shape and the surrounding clot are considered as putative factors possibly related to the intermittent appearance of the aneurysm.

    Unlike vascular Ehlers-Danlos syndrome (EDS), classic EDS is rarely associated with vascular manifestation. We report the case of a 39-year-old man who presented with acute abdominal pain. At the time of presentation, the patient was in hypovolemic shock, and computed tomography angiogram demonstrated common iliac artery dissection with rupture. He underwent an attempted endovascular repair that was converted to an open repair of a ruptured right common iliac artery dissection. Subsequent genetic testing revealed a substitution of arginine for cysteine in type I collagen, COL1A1 exon 14 c.934C>T mutation, consistent with a rare variant of classic EDS.

    Primitive neuroectodermal tumors are fairly rare in uterus. A case of uterine body primitive neuroectodermal tumor in a 32-year-old Iranian woman is presented. The patient was admitted with abdominal pain and fever and underwent emergency exploratory surgery with total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection. Posterior wall of the uterus was necrotic and ruptured and a huge tumor disrupted the uterine body. The tumor was strongly positive for CD99, NSE, and chromogranin; No reaction was seen for CD10, CD45 and myogenin. To the best of our knowledge, this is the first report of an uterine body primitive neuroectodermal tumor and the second report of uterine primitive neuroectodermal tumor from Iran.

    We review different causes, diagnoses, and treatment options of closed flexor tendon disruptions in the hand. A classification of closed tendon ruptures based on their mechanism includes traumatic tendon avulsion, spontaneous midsubstance rupture, attrition rupture, infiltrative tenosynovial rupture, and iatrogenic. Certain conditions result in tendon disruption inflicted by more than 1 of these etiologies. In rheumatoid arthritis, tendon rupture may result from attrition on an exposed rough surface, proliferative tenosynovial tendon infiltration, or steroid use.

    Atrioventricular (AV) block and endocardial fibroelastosis associated with dilated cardiomyopathy are the most common clinical manifestations of anti-Ro/SSA-mediated fetal cardiac disease. Valvar dysfunction has not been a prominent feature of this disease; however, recent anecdotal cases have suggested an association between rupture of the AV valve tensor apparatus and maternal anti-Ro/SSA antibodies. In the present study, we have described the clinical and laboratory findings and reviewed the published data for infants of anti-Ro/SSA-positive pregnancies with AV valve insufficiency due to chordal rupture from the papillary muscles. The histopathologic features of the papillary muscle and ventricular free wall and septum biopsy specimens were examined and compared to the sections of AV leaflets from 6 autopsied fetuses with anti-Ro/SSA-mediated complete AV block without chordal disruption. Specific epitopes to the p200 region of Ro52, and Ro60 antibodies were evaluated in cases with chordal rupture. Severe AV valve insufficiency was detected prenatally (as early as 34 weeks of gestation) or postnatally (as late as 182 days) after areas of patchy echogenicity were noted in the papillary muscle at 19 to 22 weeks of gestation. Postnatally, urgent valve surgery was performed in 5 of 6 patients; 1 of 6 patients died preoperatively. All patients tested positive for Ro52. Valve leaflet tissue from the autopsy specimens was normal. The ventricular free wall and septum biopsy specimens from a patient with chordal rupture showed normal tissue; however, the papillary muscle biopsy specimens demonstrated severe atrophy with near total replacement of myocytes by fibrosis and dystrophic calcifications, and negative immunochemistry findings. In conclusion, these findings have defined an underappreciated complication of fetal antibody-mediated cardiac inflammation. Copyright © 2011 Elsevier Inc. All rights reserved.

    We report the case of a 48-year-old man with neurofibromatosis presenting with sudden-onset abdominal pain, profound hypotension, and a drop in hemoglobin. CT scan demonstrated a massive hematoma within the right lobe of the liver with rupture into the peritoneal cavity. Angiography demonstrated diffuse abnormalities of the hepatic circulation with fusifom, ectatic, and stenotic segments. Acute extravasation from a peripheral branch of the right hepatic artery was identified and successfully embolized with subsequent hemodynamic stabilization of the patient. To the best of our knowledge this is the first case report of this kind in a patient with type I neurofibromatosis.

  17. Uterine Dysfunction in Biglycan and Decorin Deficient Mice Leads to Dystocia during Parturition

    Cesarean birth rates are rising. Uterine dysfunction, the exact mechanism of which is unknown, is a common indication for Cesarean delivery. Biglycan and decorin are two small leucine-rich proteoglycans expressed in the extracellular matrix of reproductive tissues and muscle. Mice deficient in biglycan display a mild muscular dystrophy, and, along with mice deficient in decorin, are models of Ehlers-Danlos Syndrome, a connective tissue anomaly associated with uterine rupture. As a variant of Ehlers-Danlos Syndrome is caused by a genetic mutation resulting in abnormal biglycan and decorin secretion, we hypothesized that biglycan and decorin play a role in uterine function. Thus, we assessed wild-type, biglycan, decorin and double knockout pregnancies for timing of birth and uterine function. Uteri were harvested at embryonic days 12, 15 and 18. Nonpregnant uterine samples of the same genotypes were assessed for tissue failure rate and spontaneous and oxytocin-induced contractility. We discovered that biglycan/decorin mixed double-knockout dams displayed dystocia, were at increased risk of delayed labor onset, and showed increased tissue failure in a predominantly decorin-dependent manner. In vitro spontaneous uterine contractile amplitude and oxytocin-induced contractile force were decreased in all biglycan and decorin knockout genotypes compared to wild-type. Notably, we found no significant compensation between biglycan and decorin using quantitative real time PCR or immunohistochemistry. We conclude that the biglycan/decorin mixed double knockout mouse is a model of dystocia and delayed labor onset. Moreover, decorin is necessary for uterine function in a dose-dependent manner, while biglycan exhibits partial compensatory mechanisms in vivo. Thus, this model is poised for use as a model for testing novel targets for preventive or therapeutic manipulation of uterine dysfunction. PMID:22253749

    Patients with PPROM are at risk for a variety of outcomes, including chorioamnionitis (CA), placental abruption (PA), or preterm labor (PTL). Competing risk regression can analyze a cohort's risk of individual outcomes while accounting for ongoing deliveries secondary to competing events. A secondary analysis of the subjects from MFMU BEAM study of neuroprotection after preterm birth (BEAM) with conservative PPROM management. Deliveries were categorized as: PA, CA, PTL, "elective" or "indicated". The association between outcomes of PA, CA or PTL and clinical predictors of twins, ethnicity, parity, gestational age at rupture, bleeding, contractions, cervical dilation, preterm birth history, weight, and genitourinary infections were evaluated via competing risk regression. 1970 subjects were included. The significance and directionality of predictors varied according to specific outcomes. Patients with twins had an increased PTL hazard (1.85) though reductions in CA- (0.66) or PA-specific (0.56) hazards. Decreased latency in African-Americans was almost entirely due to an increased CA hazard (1.44) without a significant association with PTL. Increasing gestational age at membrane rupture was associated with a decreasing hazard of CA although increasing hazard of PTL. For patients with PPROM, the hazards associated with different clinical predictors vary according to exact outcomes.

    Pancreatic cancer is one of the most lethal types of malignant tumours, commonly diagnosed at an advanced stage. The only curative treatment for this fatal disease is surgery and early diagnosis is the key to a better outcome and prognosis. In this case report we present a 57-year-old woman presenting to the emergency room with abdominal pain and weight loss. Computer Tomography (CT) imaging showed a rupture of the main pancreatic duct and a peri-pancreatic fluid collection with no evidence of a pancreatic mass. An Endoscopic Ultrasound (EUS) guided Fine Needle Aspiration (FNA) did not show any malignant cells and Carcinoembryonic Antigen (CEA) and Carbohydrate Antigen (CA) 19-9 markers were in the normal range. The patient then underwent pancreatectomy that revealed multiple microscopic foci of pancreatic adenocarcinoma with evidence of massive perineural and vascular invasion. PMID:28208932

    Bleeding from gastro-esophageal varices can often present as the first decompensating event in patients with cirrhosis. This can be a potentially life threatening event associated with a 15%-20% early mortality. We present a rare case of new onset ascites due to intra-abdominal hemorrhage from ruptured mesenteric varices; in a 37 years old male with newly diagnosed nonalcoholic steatohepatitis induced cirrhosis as the first decompensating event. The patient was successfully resuscitated with emergent evacuation of ascites for diagnosis, identification and control of bleeding mesenteric varices and eventually orthotopic liver transplantation with successful outcome. Various clinical presentations, available treatment options and outcomes of ectopic variceal bleeding are discussed in this report.

    We present the case of a 6-month-old previously healthy girl who presented with high fever, labored breathing, and an enlarged cardiac silhouette on her chest radiograph. Comprehensive evaluation discovered a ductus arteriosus aneurysm and pericardial effusion with methicillin-resistant Staphylococcus aureus bacteremia. Despite pericardiocentesis and appropriate intravenous antibiotics, there was rapid enlargement of the aneurysm and accumulation of echogenic material within the ductus arteriosus aneurysm. Infected aneurysm rupture was identified during emergency surgery. This infant also had vocal cord paresis, a likely complication of the surgery. The clinical course, diagnosis, and treatment of this patient are discussed. Infection of a ductus arteriosus or an infected ductal arteriosus aneurysm is a rare and potentially fatal clinical entity. In the era of increasing community-acquired methicillin-resistant S aureus infections, this is a diagnosis that requires a high index of suspicion.

    Concentrations of 13,14-dihydro-15-keto-PGF2 alpha (PGFM) were measured in plasma of six carefully selected primigravid women with an unripe cervix at term before and at various intervals after extra-amniotic insertion of a Foley catheter with or without methylhydroxyethylcellulose (Tylose) gel. The procedure caused an acute elevation of PGFM levels within 5 min (P less than 0.025), which was maintained for at least 6 hours in the absence of uterine activation at 179 +/- 32% of the initial values (P less than 0.01). Extra-amniotic administration of Tylose gel caused an increase in PGFM levels which was both higher and more prolonged (greater than 12 hours) than insertion of a Foley catheter alone. The observations indicate that cervical ripening without concomitant uterine activation is associated with an increase in PGFM levels. They also demonstrate that prolonged activation of (intra) uterine prostaglandin synthesis may occur several hours before the onset of labor-like uterine activity. A chance finding further suggests that spontaneous rupture of the membranes too may be preceeded by an increase in (intra) uterine prostaglandin synthesis. In their totality these observations lend strong support to the proposition that an increase in (intra) uterine prostaglandin production is a prerequisite to rather than a consequence of the initiation of labor.

    A 66-yr-old white woman presented with progressive complaints of right lateral hip and thigh pain associated with a disabling limp without an antecedent history of trauma. Physical examination revealed localized pain over the right greater trochanter to palpation. A full pain-free range of motion of the right hip was associated with weakness in the hip abductors. The patient ambulated with a compensated right Trendelenburg gait. Subsequent magnetic resonance imaging demonstrated a trochanteric bursitis and an effusion of the hip and a full-thickness tear of the gluteus medius muscle, with both a disruption and retraction of the tendon of an atretic gluteus minimus muscle. Conjoined tendon pathology of both the gluteus medius and minimus as, revealed by magnetic resonance examination, is probably more frequent than heretofore commonly recognized. In patients presenting with "intractable" complaints of a trochanteric bursitis and an ambulatory limp due to weakness in the hip abductors, imaging studies calling attention to a possible tendon rupture may be diagnostic.

We report the case of a patient with amniotic fluid embolism who was transferred to our hospital. The initial presentation was an unresponsive patient after spontaneous rupture of the membranes. The massive hypotension and coagulopathy as well as fetal bradycardia of 60 bpm led, after stabilisation of the mother, to an emergency caesarean section. The neonate expired hours later, despite neonatological intensive care. During the operation, we had to deal with massive bleeding due to the coagulopathy. Through interdisciplinary teamwork including Bakri postpartum balloon insertion through the obstetrics team, uterine artery embolism by the interventional radiologists and transfusion of blood products, the maternal life was saved and the patient was discharged 9 days after admission.

    Pre-term birth (PTB) remains the leading cause of infant mortality and morbidity. Its etiology is multifactorial, with a strong genetic component. Genetic predisposition for the two subtypes, spontaneous PTB with intact membranes (sPTB) and preterm prelabor rapture of membranes (PPROM), and differences between them, have not yet been systematically summarised. Our literature search identified 15 association studies conducted in 3,600 women on 2175 SNPs in 274 genes. We used Ingenuity software to impute gene pathways and networks related to sPTB and PPROM. Detailed insight in the defined functional ontologies clearly separated integrated datasets for sPTB and PPROM. Our analysis of upstream regulators of genes suggests that glucocorticoid receptor (NR3C1), peroxisome proliferator activated receptor γ (PPARG) and interferon regulating factor 3 (IRF3) may be sPTB specific. PPROM-specific genes may be regulated by estrogen receptor2 (ESR2) and signal transducer and activator of transcription (STAT1). The inflammatory transcription factor NFκB is linked to both sPTB and PPROM, however, their inflammatory response is distinctly different. Based on our analyses, we propose an autoimmune/hormonal regulation axis for sPTB, whilst pathways implicated in the etiology of PPROM include hematologic/coagulation function disorder, collagen metabolism, matrix degradation and local inflammation. Our hypothesis generating study has identified new candidate genes in the pathogenesis of PPROM and sPTB, which should be validated in large cohorts.

    Background The Medical Research Council (MRC) ORACLE trial evaluated the use of co-amoxiclav 375 mg and/or erythromycin 250 mg in women presenting with preterm rupture of membranes (PROM) ORACLE I or in spontaneous preterm labour (SPL) ORACLE II using a factorial design. The results showed that for women with a singleton baby with PROM the prescription of erythromycin is associated with improvements in short term neonatal outcomes, although co-amoxiclav is associated with prolongation of pregnancy, a significantly higher rate of neonatal necrotising enterocolitis was found in these babies. Prescription of erythromycin is now established practice for women with PROM. For women with SPL antibiotics demonstrated no improvements in short term neonatal outcomes and are not recommended treatment. There is evidence that both these conditions are associated with subclinical infection so perinatal antibiotic administration may reduce the risk of later disabilities, including cerebral palsy, although the risk may be increased through exposure to inflammatory cytokines, so assessment of longer term functional and educational outcomes is appropriate. Methods The MRC ORACLE Children's Study will follow up UK children at age 7 years born to 4809 women with PROM and the 4266 women with SPL enrolled in the earlier ORACLE trials. We will use a parental questionnaire including validated tools to assess disability and behaviour. We will collect the frequency of specific medical conditions: cerebral palsy, epilepsy, respiratory illness including asthma, diabetes, admission to hospital in last year and other diseases, as reported by parents. National standard test results will be collected to assess educational attainment at Key Stage 1 for children in England.

For women with SPL antibiotics demonstrated no improvements in short term neonatal outcomes and are not recommended treatment. There is evidence that both these conditions are associated with subclinical infection so perinatal antibiotic administration may reduce the risk of later disabilities, including cerebral palsy, although the risk may be increased through exposure to inflammatory cytokines, so assessment of longer term functional and educational outcomes is appropriate. The MRC ORACLE Children's Study will follow up UK children at age 7 years born to 4809 women with PROM and the 4266 women with SPL enrolled in the earlier ORACLE trials. We will use a parental questionnaire including validated tools to assess disability and behaviour. We will collect the frequency of specific medical conditions: cerebral palsy, epilepsy, respiratory illness including asthma, diabetes, admission to hospital in last year and other diseases, as reported by parents. National standard test results will be collected to assess educational attainment at Key Stage 1 for children in England. This study is designed to investigate whether or not peripartum antibiotics improve health and disability for children at 7 years of age. The ORACLE Trial and Children Study is registered in the Current Controlled Trials registry. ISCRTN 52995660.

    Many adverse pregnancy outcomes (APOs), including spontaneous preterm birth (PTB), are associated with placental dysfunction. Recent clinical and experimental evidences suggest that premature aging of the placenta may be involved in these events. Although placental aging is a well-known concept, the mechanisms of aging during normal pregnancy and premature aging in APOs are still unclear. This review was conducted to assess the knowledge on placental aging related biochemical changes leading to placental dysfunction in PTB and/or preterm premature rupture of membranes (pPROM). We performed a systematic review of studies published over the last 50 years in two electronic databases (Pubmed and Embase) on placental aging and PTB or pPROM. The search yielded 554 citations, 30 relevant studies were selected for full-text review and three were included in the review. Only one study reported oxidative stress-related aging and degenerative changes in human placental membranes and telomere length reduction in fetal cells as part of PTB and/or pPROM mechanisms. Similarly, two animal studies reported findings of decidual senescence and referred to PTB mechanisms. Placental and fetal membrane oxidative damage and telomere reduction are linked to premature aging in PTB and pPROM but the risk factors and biomolecular pathways causing this phenomenon are not established in the literature. However, no biomarkers or clinical indicators of premature aging as a pathology of PTB and pPROM have been reported. We document major knowledge gaps and propose several areas for future research to improve our understanding of premature aging linked to placental dysfunction. Copyright © 2015 Elsevier Ltd.

    Uterine arteriovenous malformation is a rare but life-threatening condition that accounts for 1-2% of massive vaginal bleeding. Uterine arteriovenous malformations are less common after menopause. The condition can be diagnosed using Doppler ultrasound, magnetic resonance imaging, computed tomography, and pelvic angiography. We report a postmenopausal patient with a uterine arteriovenous malformation who underwent emergency hysterectomy for sudden onset of life-threatening uterine bleeding following an initially successful but ultimately failed uterine artery embolization. Interestingly, it was not difficult to ligate and cut the dilated vessels and we were able to safely perform the hysterectomy with little bleeding in the operative field. The hysterectomy was successful, with most of the intraoperative vaginal blood loss due to the ruptured arteriovenous malformation. One year after surgery, the patient has had no vaginal bleeding. We consider hysterectomy to be a comparatively safe and effective therapeutic option for postmenopausal women who suffered from uterine arteriovenous malformations with life-threatening uterine bleeding.

    It is well-known that multiparity and advanced age are major risk factors for pelvic organ prolapse which can rarely complicate pregnancy. We present the youngest case of uterine prolapse during pregnancy. She admitted with ruptured membranes at the 36th week of gestation and irreducible prolapse. As the edematous and thick, trapped and ulcerated cervix was not reducible, labor was obstructed due to cervical dystocia and a cesarean delivery was decided. A live male infant weighing 3100 gram was delivered. The prolapsed uterus recovered spontaneously following the cesarean operation. Uterine prolapse during pregnancy should be managed conservatively. It seems to be essential to perform elective cesarean section because of the risk of possible obstructed labor. We observed a rapid recovery of the anatomy, probably due to the young age.

    Uterine artery pseudoaneurysm can occur after cesarean section or traumatic delivery, usually manifesting as postpartum hemorrhage. Pregnant women after adenomyomectomy sometimes suffer some adverse events, among which uterine rupture has been widely acknowledged. We describe a post-abortive woman who had uterine artery pseudoaneurysm occupying the entire uterine cavity. She underwent adenomyomectomy and became pregnant. She experienced a missed abortion and underwent evacuation and curettage, which caused bleeding. Several days later, ultrasound revealed an intrauterine mass with marked blood flow. Angiography revealed the un-ruptured left uterine artery pseudoaneurysm, with arterial embolization stopping the flow within the pseudoaneurysm. Adenomyomectomy with subsequent curettage was considered to have caused the pseudoaneurysm. We must be cautious that pseudoaneurysm may occur in post-abortive women after adenomyomectomy. © 2013 The Authors.

    A 71-year-old woman was admitted with panperitonitis, hyperkalemia and acute renal failure. Immediately after a large amount of ascites had been drained by laparotomy, hyperkalemia and acidosis were remarkably improved. During the operation, rupture of the urinary bladder was detected and repaired. The level of potassium and renal function became normal the next morning, and it seemed that peritoneal-self-dialysis had been related to hyperkalemia and acute renal failure. Rupture of the urinary bladder is very rare but should be considered in any cases of acute abdomen with hyperkalemia and acute renal failure.

    Various drugs used to stop premature uterine contractions are discussed in the paper. Particular attention is paid to beta-mimetic drugs. The results of ming Partusisten, one of beta-mimetic drugs, is presented on the material of 104 patients with threatening immature and premature labour. Partusisten was administered in the form of intravenous drip infusion or tablets. During treatment monitoring of the uterine contractility and of foetal heart rate took place. Inhibition of the uterine contraction activity was successful in 100 per cent of cases. In 60,9 per cent in the group of threatening immature labour and in 38,1 per cent in the group threatening premature labour, the delay of delivery was more then 28 days. The delay of delivery by 48 hours was 87 per cent and 84 per cent in both groups respectively. Tachycardia was one of the first side effects observed in 15,2 per cent of cases. There is also presented an example of pregnancy when delivery was delayed by 21 days in spite of premature outflow of amniotic fluid (at a high rupture of membrane). The authors are of the opinion that Partusisten is very effective and gives little side effects, preventing premature uterine contractions. Dosage should be individualized according to the case and labour advancement, and should be based on topographic evaluation of uterine contraction. Negative influence of the drug on foetuses was not observed.

  6. Resistance of a vaccinia virus A34R deletion mutant to spontaneous rupture of the outer membrane of progeny virions on the surface of infected cells

    The extracellular form of vaccinia virus is referred to as an enveloped virion (EV) because it contains an additional lipoprotein membrane surrounding the infectious mature virion (MV) that must be discarded prior to cell fusion and entry. Most EVs adhere to the surface of the parent cell and mediate spread of the infection to adjacent cells. Here we show that some attached EVs have ruptured envelopes. Rupture was detected by fluorescence microscopy of unfixed and unpermeabilized cells using antibodies to the F13 and L1 proteins, which line the inner side of the EV membrane and the outer side of the MV membrane, respectively. The presence of ruptured EV membranes was confirmed by immunogold transmission electron microscopy. EVs with broken membranes were present on several cell lines examined including one deficient in glycosaminoglycans, which are thought to play a role in breakage of the EV membrane prior to fusion of the MV. No correlation was found between EVs with ruptured membranes and actin tail formation. Studies with several mutant viruses indicated that EV membranes lacking the A34 protein were unbroken. This result was consistent with other properties of A34R deletion mutants including resistance of the EV membrane to polyanions, small plaque formation and low infectivity that can be increased by disruption of the EV membrane by freezing and thawing.

    Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation). The vascular type accounts for less than 4% of all Ehlers-Danlos cases and usually has a poor prognosis due to life threatening vascular ruptures and difficult, frequently unsuccessful surgical and vascular interventions. In 70% of cases, vascular rupture or dissection, gastrointestinal perforation, or organ rupture is a presenting sign. We present a case of genetically proven vascular Ehlers-Danlos with fatal recurrent retroperitoneal hemorrhages secondary to a ruptured right common iliac artery dissection in a 30-year-old male. This case highlights the need to suspect collagen vascular disorders when a young adult presents with unexplained retroperitoneal hemorrhage, even without family history of such diseases.

    Subsequent pregnancy following an interstitial pregnancy is rare. The risk of uterine rupture may be increased in this situation. Uterine selective embolization has been proposed as an effective treatment. However, no further pregnancy has ever been described after this method of management. We are reporting a case of subsequent pregnancy following interstitial pregnancy managed by embolization. The pregnancy was uneventful. A healthy male infant was delivered by C-section. This case supports the hypothesis that selective embolization for interstitial pregnancy may respect fertility. However, as actual risk of uterine rupture in subsequent pregnancies remains unknown, a C-section is advised.

    Visceral artery aneurysms (VAAs), unlike aortic aneurysms, are very rare, but are also a potentially lethal vascular disease. Jejunal artery aneurysms only account for less than 3% of VAAs, but have a 30% risk of rupture, with 20% death rate, presenting with only few and vague symptoms. We report the case of a 76-year-old man presenting at the emergency department (ED) with a crampy epigastric pain and vomiting. An ultrasound performed diagnosed free abdominal fluid and immediate CT scan diagnosed jejunal artery aneurysm spontaneously rupturing, followed by hypovolaemic shock. Emergent surgery was undertaken, and aneurysmectomy, followed by partial enterectomy with primary anastomosis were performed, because of segmentary jejunal ischaemia. The patient's recovery was unremarkable. High level of suspicion, rapid diagnosis capability and prompt surgical or endovascular intervention, as well as an effective teamwork in the ED are critical to avoid the devastating consequences of ruptured VAAs.

    To evaluate the benefits and risks of labor induction in patients previously delivered by at least one low transverse cesarean section. To define how labor should be managed in patients attempting a vaginal birth after cesarean section (VBAC). A literature search was performed using the Pubmed(®) and Cochrane(®) databases. Foreign societies guidelines were also consulted. Labor induction is associated with an increased risk of uterine rupture that could be estimated at 1% with oxytocine and 2% with vaginal prostaglandins (Level 2). Mechanical methods have been insufficiently studied. Misoprostol seems to dramatically increase the risk of uterine rupture (Level 3). The routine use of intrauterine pressure catheter does not prevent uterine rupture (Professional agreement). A moderate increase of uterine rupture was also found with augmentation (Level 3). The risk of uterine rupture increases when cervical dilatation is arrested for 3 hours or more when a good uterine dynamic is obtained (Professional agreement). The use of epidural analgesia should be encouraged (Grade C). Routine digital exploration of the uterine scare postpartum is not necessary (Grade C). Women attempting a VBAC should be aware of the modalities of labor management. When labor induction is warranted, women should also be informed of the indication and the increased risk of uterine rupture. The choice of labor induction method should take into consideration maternal and obstetrical characteristics. Copyright © 2012. Published by Elsevier Masson SAS.

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

    In the present study synovial fluid (SF) obtained from the stifle joint of healthy adult dogs and of dogs after cranial cruciate ligament rupture was analyzed regarding its rheological characteristics according to the condition of the joint. The viscoelastic and shear flow properties were measured at 25 and 38 degrees C. The results showed that the healthy SF exhibits practically temperature independent viscosity curve and satisfactory viscoelastic characteristics, i.e. G' > G'', over frequencies of 0.05-5 Hz, and characteristic relaxation time lambda of the order of magnitude of 100 s. Creep measurements demonstrate that the zero shear viscosity was in the range of 10-100 Pa s. In shear flow viscosity measurements, by increasing gamma from 10(-4) s(-1) up to 10(3) s(-1), non-Newtonian shear thinning behavior was observed and the viscosity values were decreased from 10(3) to 0.1 Pa s. On the contrary, in pathological conditions of cranial cruciate ligament rupture (CCLR), the measured viscosity was found drastically reduced, i.e. between 100 and 10 mPa s. The CCLR synovial fluid, similar to healthy SF, exhibits insignificant temperature dependence. The present study showed also that about one week after a surgery for CCLR repair the SF exhibits non-Newtonian behavior of dilute polymers. After two weeks from the operation, however, the rheological behavior converges to the one of healthy SF.

    Visfatin, a novel adipokine originally discovered as a pre-B-cell colony enhancing factor, is expressed by amniotic epithelium, cytotrophoblast, and decidua and is over-expressed when fetal membranes are exposed to mechanical stress and/or pro-inflammatory stimuli. Visfatin expression by fetal membranes is dramatically up-regulated after normal spontaneous labor. The aims of this study were to determine if visfatin is detectable in amniotic fluid (AF) and whether its concentration changes with gestational age, spontaneous labor, preterm prelabor rupture of membranes (preterm PROM) and in the presence of microbial invasion of the amniotic cavity (MIAC). In this cross-sectional study, visfatin concentration in AF was determined in patients in the following groups: 1) mid-trimester (n=75); 2) term not in labor (n=27); 3) term in spontaneous labor (n=51); 4) patients with preterm labor with intact membranes (PTL) without MIAC who delivered at term (n=35); 5) patients with PTL without MIAC who delivered preterm (n=52); 6) patients with PTL with MIAC (n=25); 7) women with preterm PROM without MIAC (n=26); and 8) women with preterm PROM with MIAC (n=26). Non-parametric statistics were used for analysis. 1) The median AF concentration of visfatin was significantly higher in patients at term than in mid-trimester; 2) Among women with PTL who delivered preterm, the median visfatin concentration was significantly higher in patients with MIAC than those without MIAC; 3) Similarly, patients with PTL and MIAC had a higher median AF visfatin concentration than those with PTL who delivered at term; 4) Among women with preterm PROM, the median AF visfatin concentration was significantly higher in patients with MIAC than those without MIAC. 1) Visfatin is a physiologic constituent of AF; 2) The concentration of AF visfatin increases with advancing gestational age; 3) AF visfatin concentration is elevated in patients with MIAC, regardless of the membrane status, suggesting that

Spontaneous rupture of pyometra in cervical cancer presenting as generalized peritonitis is very rare. Only four cases have been described in the English literature to the best of our knowledge and from a PubMed search. The index case is an elderly postmenopausal female who was diagnosed with cervical cancer, started on radiotherapy and presented with features of generalized peritonitis. Contrast-enhanced CT revealed uterine perforation at the fundus with multiple abdominal and pelvic collections. A brief review of all the cases of ruptured pyometra in cervical cancer in the literature and a discussion of the role of imaging is presented. PMID:19419914

Le patient a été traité, après drainage vésical, par une irradiation externe associée à une chimiothérapie par cisplatine, et est décédé après progression de la maladie sur un an.La rupture spontanée de l'urètre transtumorale est un mode de découverte exceptionnel témoignant d'une évolution locale défavorable, ce qui rend ces tumeurs difficilement opérables. Cependant, l'espoir actuel réside dans des protocoles thérapeutiques associant radiothérapie et chimiothérapie.

    Uterine artery pseudoaneurysm (UAP) has been considered to occur very rarely after traumatic delivery/abortion, and is usually detected after its rupture, yielding massive bleeding. Our hypothesis is: some UAP may be undetected without massive bleeding and may spontaneously resolve, and, thus, may not require transarterial embolization (TAE). We attempted: (1) to detect both ruptured and non-ruptured UAP, thereby characterizing candidates of spontaneously resolving UAP, and (2) to confirm that UAP is not rare and not always associated with traumatic events. This was a retrospective observational study of 50 women with angiographically confirmed UAP and treated by TAE. Angiograms and medical charts were retrieved to examine the associations among symptoms, ultrasound findings, and extravasation. Gray-scale ultrasound was performed for all women after delivery or abortion as our routine practice. UAP occurred in 3-6/1000 deliveries and 40% occurred after non-traumatic deliveries/abortion. While 36% had active vaginal bleeding at admission, 64% did not. While 100% of patients with current active bleeding showed extravasation from the pseudoaneurysmal sac, patients without it showed a varied incidence of extravasation depending on the bleeding pattern/history and ultrasound findings. Interestingly, all patients with current bleeding (-), bleeding history (+), and ultrasound-discernable-intrauterine low echoic mass (-) were devoid of extravasation, suggesting that UAP may show progression to thrombosis and, thus, resolve spontaneously. UAP may not be so rare and not associated with traumatic delivery/abortion. Some UAP may resolve, and, thus, may not require TAE, at least immediately. Copyright © 2016 Elsevier Ireland Ltd.

    This study analyzes uterine motility in 12 women with a bicornuate uterus using the results of the recordings of endo-uterine pressure, obtained with two balloon-closed catheters. Seven patients had symmetric uterine cavities, while the rest (5 patient) had very dissimilar ones. The registration of the uterine motility was carried out during various phases of the cycle and after the administration of two drugs (oxitocin and methylergobasine), with the following results: the bicornuate uterus has a spontaneous activity similar to that of a normal uterus. A similar contractile response was observed in the uteri with two anatomically symmetric horns, whereas a dissimilar response was typical of the uteri with marked anatomic differences between the two horns.

    To evaluate the clinical outcomes of ruptured dermoid cysts. A multicenter, retrospective study of all cases of periorbital and orbital dermoid cysts with histopathological evidence of rupture, including those with clinical rupture, was performed over a 10-year period. Demographics and clinical outcomes of ruptured dermoid cysts were recorded. Persistent inflammation was defined as the presence of edema, erythema, and discomfort for at least 28 days. Eighty-six cases of dermoid cysts were identified. Median age was 5.5 (range, 1-63) years. Location of cyst was either periorbital (n = 60, 70%) or orbital (n = 26, 30%). There were 29 cases with clinically apparent rupture: 27 surgically ruptured (93%) and 2 spontaneous rupture (7%). Persistent inflammation was found in 1 spontaneous cyst rupture case (50%) and 1 surgically ruptured cyst (3.7%). Older age (p = 0.01) and bony attachment (p = 0.001) were significant factors for cyst rupture, while there was no influence from cyst location (p = 0.14). Persistent inflammation is uncommon after surgical rupture of dermoid cysts, but likely after spontaneous rupture. Older age and bony attachment are risk factors for cyst rupture.

    Spontaneous coronary artery dissection (SCAD) is an unusual, but increasingly recognized, cause of ST-elevation myocardial infarction (STEMI), especially among younger patients without conventional risk factors for coronary artery disease (CAD). Although dissection of the coronary intima or media is a hallmark finding, hematoma formation within the vessel wall is often present. It remains unclear whether dissection or hematoma is the primary event, but both may cause luminal stenosis and occlusion. The diagnosis of SCAD is made principally with invasive coronary angiography, although adjunctive intracoronary imaging modalities may increase the diagnostic yield. In STEMI patients, the decision whether to pursue primary percutaneous coronary intervention (PCI) or appropriate conservative medical therapy is based on clinical presentation, the extent of the dissection, the critical anatomy involvement, and the amount of ischaemic myocardium at risk. In this case report, we present two cases of young women with SCAD and STEMI, successfully treated with primary PCI. We briefly illustrate the characteristic aspects of the angiographic presentation and intravascular ultrasound-guided treatment. SCAD should always be considered in young STEMI patients without conventional risk factors for CAD with primary angioplasty to be required in patients with ongoing myocardial ischemia.

    Objective Visfatin, a novel adipokine originally discovered as a pre-B-cell colony enhancing factor, is expressed by amniotic epithelium, cytotrophoblast, and decidua and is over-expressed when fetal membranes are exposed to mechanical stress and/or pro-inflammatory stimuli. Visfatin expression by fetal membranes is dramatically up-regulated after normal spontaneous labor. The aims of this study were to determine if visfatin is detectable in amniotic fluid (AF) and whether its concentration changes with gestational age, spontaneous labor, preterm prelabor rupture of membranes (preterm PROM) and in the presence of microbial invasion of the amniotic cavity (MIAC). Methods In this cross-sectional study, visfatin concentration in AF was determined in patients in the following groups: 1) mid-trimester (n=75); 2) term not in labor (n=27); 3) term in spontaneous labor (n=51); 4) patients with preterm labor with intact membranes (PTL) without MIAC who delivered at term (n=35); 5) patients with PTL without MIAC who delivered preterm (n=52); 6) patients with PTL with MIAC (n=25); 7) women with preterm PROM without MIAC (n=26); and 8) women with preterm PROM with MIAC (n=26). Non-parametric statistics were used for analysis. Results 1) The median AF concentration of visfatin was significantly higher in patients at term than in midtrimester; 2) Among women with PTL who delivered preterm, the median visfatin concentration was significantly higher in patients with MIAC than those without MIAC; 3) Similarly, patients with PTL and MIAC had a higher median AF visfatin concentration than those with PTL who delivered at term; 4) Among women with preterm PROM, the median AF visfatin concentration was significantly higher in patients with MIAC than those without MIAC. Conclusions 1) Visfatin is a physiologic constituent of AF; 2) The concentration of AF visfatin increases with advancing gestational age; 3) AF visfatin concentration is elevated in patients with MIAC, regardless of the

    Premature rupture of membranes is defined as expulsion of the amniotic liquid occurring at least 1 hour before initiation of uterine contractions and without apparent cervical changes. According to the literature, premature rupture of membranes occurs in 2-15% of all pregnancies, with an average of 10%. The etiology is considered multifactorial, and treatment remains controversial. A retrospective review was conducted to determine the occurrence of maternal or perinatal morbidity and mortality in 230 cases of premature rupture of membranes in a social security hospital in Santo Domingo, Dominican Republic, observed between 1983-88. Premature rupture occurred in 3.5% of cases according to the records. 37.4% of affected mothers were 21-25 years old and 69.6% were 21.30. 62.9% of the women were nulliparas. 2.2% had had no prenatal care, 59.1% had insufficient prenatal care, defined as 1-5 visits and only 36.1% had 6 or more visits. 81.3% of ruptures occurred at 37-42 weeks of gestation. In 64.8% of cases the pregnancy was terminated within 1-24 hours and 35.2% were considered prolonged. Prematurity and low birth weight was the most common perinatal disorders, affecting 10.9%. Respiratory difficulty syndrome affected 4.3%. 60% of infants with respiratory problems were born at less than 37 weeks gestation. Neonatal sepsis occurred in 3% of cases and prolapse of the umbilical cord in 1.3%. Perinatal mortality averaged 2.6%. Prematurity was a factor in all cases. Respiratory distress syndrome and neonatal sepsis were each present in 50% of cases and hyperbilirubinemia in 33%. 8.7% of the mothers developed chorioamnionitis. Only 23.9% terminated their pregnancies spontaneously. Oxytocin was used to induce labor in 30.4% and cesareans were performed in 44.8%.

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

    Medical abortion in women with the scar of a classical caesarean section (CS) and a large uterine leiomyoma is rarely attempted; it carries the risk of uterine rupture and haemorrhage. A 34-year-old multiparous woman with prior classical CS and a 14 × 10 × 9 cm leiomyoma arising from the uterine isthmus had an induced abortion at 14 weeks' gestation. Mechanical cervical priming with Dilapan(®)-S followed by vaginal misoprostol administration resulted in the uncomplicated expulsion of the uterine contents. An early second trimester medical abortion with misoprostol was successfully performed in a woman with prior classical CS and a large uterine leiomyoma.

    The Earth's free surface is a critical boundary for dynamic rupture propagation that plays an important role in influencing rupture patterns, especially the subshear-to-supershear transition. Surfaces with irregular topographies, which are prevalent in nature, may change this supershear transition mechanism. Using the curved grid finite-difference method, which can be employed to solve elastodynamic equations in curvilinear coordinates, we model spontaneous dynamic rupture on faults with irregular free surfaces. We investigate its effect on the dynamic rupture process with extensive numerical simulations. The simulated results show that the effect of topography on a rupture is dependent on the shape and epicentral distance of the topography.

    Two patients with spontaneous medial plantar fascia rupture due to a definite injury with no prior symptoms, were referred to our institution. Clinically, there was a tender lump in the sole, and magnetic resonance imaging confirmed the diagnosis. Nonoperative treatment was sufficient in curing the acute total rupture. Endoscopic release was used on the partially ruptured plantar fascia, but it is probably more optimal in the acute phase. The literature provides no comparative data on operative or nonoperative treatment efficacy for this rare condition.

  11. Guidelines for the management of spontaneous preterm labor.

    PubMed

    Di Renzo, Gian Carlo; Roura, Lluis Cabero

    Preterm birth is defined as delivery at <37 completed weeks of pregnancy (World Health Organization). Spontaneous preterm birth (SPB) includes preterm labor, preterm spontaneous rupture of membranes, preterm premature rupture of membranes (PPROM) and cervical weakness; it does not include indicated preterm delivery for maternal or fetal conditions. Early SPB (<32 weeks' gestation) is associated with an increased higher perinatal mortality rate, inversely proportional to gestational age. The pathophysiologic events that trigger SPB are largely unknown but include decidual hemorrhage (abruption), mechanical factors (uterine overdistention or cervical incompetence), and hormonal changes (perhaps mediated by fetal or maternal stress). In addition, several cervicovaginal infections have been associated with preterm labor. SPB is also the leading cause of long-term morbidity, including neurodevelopmental handicap, cerebral palsy, seizure disorders, blindness, deafness and non-neurological disorders, such as bronchopulmonary dysplasia and retinopathy of prematurity. Delaying delivery may reduce the rate of long-term morbidity by facilitating the maturation of developing organs and systems. The benefits of administration of antepartum glucocorticosteroids to reduce the incidence and severity of respiratory distress syndrome may be exploited by delay. Delay may also permit transfer of the fetus in utero to a center with neonatal intensive care unit facilities. There is considerable variation in the way that spontaneous preterm labor (SPTL) is diagnosed, managed and treated internationally. The development of clinical guidelines requires an evidence-based approach to improve outcome and allow more efficient use of resources. With recent advances in our understanding of the etiology and mechanisms of SPTL and the availability of safer, more specific tocolytics, it was felt that guidelines should be developed to achieve, if possible, an European consensus in patient diagnosis

  12. An insight on correlations between kinematic rupture parameters from dynamic ruptures on rough faults

    2017-04-01

    We examine the spatial interdependence between kinematic parameters of earthquake rupture, which include slip, rise-time (total duration of slip), acceleration time (time-to-peak slip velocity), peak slip velocity, and rupture velocity. These parameters were inferred from dynamic rupture models obtained by simulating spontaneous rupture on faults with varying degree of surface-roughness. We observe that the correlations between these parameters are better described by non-linear correlations (that is, on logarithm-logarithm scale) than by linear correlations. Slip and rise-time are positively correlated while these two parameters do not correlate with acceleration time, peak slip velocity, and rupture velocity. On the other hand, peak slip velocity correlates positively with rupture velocity but negatively with acceleration time. Acceleration time correlates negatively with rupture velocity. However, the observed correlations could be due to weak heterogeneity of the slip distributions given by the dynamic models. Therefore, the observed correlations may apply only to those parts of rupture plane with weak slip heterogeneity if earthquake-rupture associate highly heterogeneous slip distributions. Our findings will help to improve pseudo-dynamic rupture generators for efficient broadband ground-motion simulations for seismic hazard studies.

    Miscarriage is the spontaneous loss of a pregnancy before the fetus is viable. Uterine muscle relaxant drugs have been used for women at risk of miscarriage in the belief they relax uterine muscle, and hence reduce the risk of miscarriage. To assess the effects for the woman and her baby of uterine muscle relaxant drugs when used for threatened miscarriage. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (4 May 2004), and the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2004). Randomised trials were included, and quasi-randomised trials were excluded. The participants were women with a pregnancy of less than 20 weeks' gestation having a threatened miscarriage. The interventions were any uterine muscle relaxing drugs (including tocolytic and antispasmodic agents) compared with either placebo or no drug. Primary outcomes for the review were miscarriage: defined as spontaneous pregnancy loss before fetal viability, baby death (stillbirth or neonatal death) and maternal death. Both review authors independently assessed studies for eligibility and trial quality, and extracted data. One poor quality trial (170 women) was included. This compared a beta-agonist with placebo. There was a lower risk of intrauterine death associated with the use of a beta-agonist (relative risk (RR) 0.25, 95% confidence interval (CI) 0.12 to 0.51). Preterm birth was the only other outcome reported (RR 1.67, 95% CI 0.63 to 4.38). There is insufficient evidence to support the use of uterine muscle relaxant drugs for women with threatened miscarriage. Any such use should be restricted to the context of randomised trials.

  14. Peridynamic Modeling of Ruptures in Biomembranes

    Jesorka, Aldo; Bertoldi, Katia

    2016-01-01

    We simulate the formation of spontaneous ruptures in supported phospholipid double bilayer membranes, using peridynamic modeling. Experiments performed on spreading double bilayers typically show two distinct kinds of ruptures, floral and fractal, which form spontaneously in the distal (upper) bilayer at late stages of double bilayer formation on high energy substrates. It is, however, currently unresolved which factors govern the occurrence of either rupture type. Variations in the distance between the two bilayers, and the occurrence of interconnections (“pinning sites”) are suspected of contributing to the process. Our new simulations indicate that the pinned regions which form, presumably due to Ca2+ ions serving as bridging agent between the distal and the proximal bilayer, act as nucleation sites for the ruptures. Moreover, assuming that the pinning sites cause a non-zero shear modulus, our simulations also show that they change the rupture mode from floral to fractal. At zero shear modulus the pores appear to be circular, subsequently evolving into floral pores. With increasing shear modulus the pore edges start to branch, favoring fractal morphologies. We conclude that the pinning sites may indirectly determine the rupture morphology by contributing to shear stress in the distal membrane. PMID:27829001

  16. Interferons and uterine receptivity.

    PubMed

    Bazer, Fuller W; Spencer, Thomas E; Johnson, Gregory A

    2009-01-01

    This article focuses on the potential roles of interferons (IFNs) in establishing uterine receptivity to implantation. A common feature of the peri-implantation period of pregnancy in most mammals is production of type I and/or type II IFNs by trophoblasts that induce and/or stimulate expression of an array of IFN-stimulate genes (ISGs). These effects range from pregnancy recognition signaling in ruminants through IFN tau to effects on cellular functions of the uterus and uterine vasculature. For actions of IFNs, progesterone (P4) is permissive to the expression of many effects and to the expression of ISGs that are induced directly by an IFN or induced by P4 and stimulated by an IFN in a temporal and/or cell-specific manner. Uterine receptivity to implantation is P4 dependent; however, implantation events are preceded by loss of expression of progesterone (PGR) and estrogen (ESR1) receptors by uterine epithelia. Therefore, P4 likely acts via PGR-positive stromal cells to induce expression of fibroblast growth factors-7 and -10 and/or hepatocyte growth factor (progestamedins) that then act via their respective receptors on uterine epithelia and trophectoderm to affect expression of ISGs. The permissive effects of P4 on the expression of ISGs and the effects of P4 to induce and IFNs to stimulate gene expression raise the question of whether uterine receptivity to implantation requires P4 and IFN to activate unique, but complementary, cell signaling pathways. Uterine receptivity to implantation, depending on species, involves changes in the expression of genes for the attachment of trophectoderm to the uterine lumenal epithelium (LE) and superficial glandular epithelium (sGE), modification of the phenotype of uterine stromal cells, the silencing of PGR and ESR1 genes, the suppression of genes for immune recognition, alterations in membrane permeability to enhance conceptus-maternal exchange of factors, increased vascularity of the endometrium, activation of genes for

    The article presents a survey of preterm rupture of the amniotic membranes at term (more than 1 hour prior to uterine contractions) and preterm (< 37 weeks). The diagnosis of rupture can be suspected from the history alone in 90% of the cases, and confirmed by inspection. In doubtful cases the pH in fluid from the posterior fornix of the vagina is determined and microscopy is performed. Amniotic fluid is alkaline. Microscopy of a dried specimen shows "ferning" when amniotic fluid is present (crystallization test). Staining with Nil blue will reveal orange foetal cells in fresh specimens, usually only late in pregnancy (after the 38 week). The crystallization test is useful, however, in all three trimesters. The cause of membrane rupture and of chorioamnionitis may be infection. Chorioamnionitis is a serious clinical condition, but can be subclinical and may occur with intact membranes. It can lead to preterm delivery. It is important that chorioamnionitis be diagnosed (maternal fever, tachycardia, uterine contractions, abdominal pain, foul smelling vaginal discharge and elevated C-reactive protein). The condition is treated with antibiotics and labour must be induced.

    2014-01-01

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

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

  20. Mechanics of Multifault Earthquake Ruptures

    2015-12-01

    The 2010 El Mayor-Cucapah earthquake of magnitude Mw 7.2 produced the most complex rupture ever documented on the Pacific-North American plate margin, and the network of high- and low-angle faults activated in the event record systematic changes in kinematics with fault orientation. Individual faults have a broad and continuous spectrum of slip sense ranging from endmember dextral strike slip to normal slip, and even faults with thrust sense of dip slip were commonly observed in the aftershock sequence. Patterns of coseismic slip are consistent with three-dimensional constrictional strain and show that integrated transtensional shearing can be accommodated in a single earthquake. Stress inversions of coseismic surface rupture and aftershock focal mechanisms define two coaxial, but permuted stress states. The maximum (σ1) and intermediate (σ2) principal stresses are close in magnitude, but flip orientations due to topography- and density-controlled gradients in lithostatic load along the length of the rupture. Although most large earthquakes throughout the world activate slip on multiple faults, the mechanical conditions of their genesis remain poorly understood. Our work attempts to answer several key questions. 1) Why do complex fault systems exist? They must do something that simple, optimally-oriented fault systems cannot because the two types of faults are commonly located in close proximity. 2) How are faults with diverse orientations and slip senses prepared throughout the interseismic period to fail spontaneously together in a single earthquake? 3) Can a single stress state produce multi-fault failure? 4) Are variations in pore pressure, friction and cohesion required to produce simultaneous rupture? 5) How is the fabric of surface rupture affected by variations in orientation, kinematics, total geologic slip and fault zone architecture?

    The induction of labour (IOL) may be associated with complications for pregnant women. The aim was to assess the differences in the number of caesarean sections between spontaneous or induced labour. Historical groups from 841 women with induced labour and 2,534 women with an spontaneous onset of labour over a three- year period (from 2009 to 2011). They were carried out in "Mancha Centro" Hospital (Alcázar de San Juan). It was used a multivariate analysis through binary logistic regression to control confounding variables. The prevalence of IOL was 22,9%. The most frequent indications were: Premature Rupture of Membranes (22,7%), bad- controlled Diabetes (22,5%). It was reported a relation between induced labour and cesarean section risk due to parity (nulliparous OR= 2.68, IC 95%: 2.15- 3.34 and multiparous OR= 2.10, IC 95%: 1.72- 2.57). Postterm pregnancy (37,1%), pathological monitor (35.3%) and hypertensive diseases of pregnancy (34%) reported the highest risks of cesarean section. The IOL was related to other factors: a long- time length first -stage of labour (OR= 6.00; IC 95%: 4.02- 8.95), use of epidural analgesia (OR= 3.10; IC 95%: 2.24- 4.29) and blood transfusion needs (OR= 3.33; IC 95%: 1.70- 9.67). Independently of parity, The IOL increases the risk to: have a longer duration first- stage, use epidural analgesia, need a blood transfusion and have a cesarean section. This relation is stronger when induction is due to postterm pregnancy, pathological monitor or hypertensive diseases. No relation was found among induced labour and second- stage duration, episiotomy, perineal tears, excessive blood loss or uterine rupture.

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

  10. Uterine activity, sperm transport, and the role of boar stimuli around insemination in sows.

    PubMed

    2005-01-15

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

    Women who undergo vaginal birth apply uterine fundal pressure during the second stage of labor. Uterine fundal pressure is done manually with the practitioner's forearms, elbows, or palms pressed on the uterine fundus at a 30° to 45° angle to the maternal spine in the direction of the pelvis. The pressure is applied in the longitudinal direction. Gentle, firm, and steady pressure is recommended. The various side effects of applying uterine fundal pressure include: uterine rupture, postpartum urinary retention, severe perineal trauma and pain, rib fracture, postpartum dyspareunia, and potential neonatal distress or trauma. Therefore, caution is recommended in the application of uterine fundal pressure. Thus, only well-trained and experienced medical staff or nurses should be allowed to practice this intervention.

    Uterine wall tension is thought to be an important determinant of the onset of labor in pregnant women. We characterize human uterine wall tension using ultrasound from the second trimester of pregnancy until parturition and compare preterm, term and twin pregnancies. A total of 320 pregnant women were followed from first antenatal visit to delivery during the period 2000–2004 at the John Hunter Hospital, NSW, Australia. The uterine wall thickness, length, anterior-posterior diameter and transverse diameter were determined by serial ultrasounds. Subjects were divided into three groups: women with singleton pregnancies and spontaneous labor onset, either preterm or term and women with twin pregnancies. Intrauterine pressure results from the literature were combined with our data to form trajectories for uterine wall thickness, volume and tension for each woman using the prolate ellipsoid method and the groups were compared at 20, 25 and 30 weeks gestation. Uterine wall tension followed an exponential curve, with results increasing throughout pregnancy with the site of maximum tension on the anterior wall. For those delivering preterm, uterine wall thickness was increased compared with term. For twin pregnancies intrauterine volume was increased compared to singletons (), but wall thickness was not. There was no evidence for increased tension in those delivering preterm or those with twin gestations. These data are not consistent with a role for high uterine wall tension as a causal factor in preterm spontaneous labor in singleton or twin gestations. It seems likely that hormonal differences in multiple gestations are responsible for increased rates of preterm birth in this group rather than increased tension. PMID:20585649

    2013-01-01

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

    Abnormal uterine bleeding is a frequent condition in Gynecology. It may impact physical, emotional sexual and professional aspects of the lives of women, impairing their quality of life. In cases of acute and severe bleeding, women may need urgent treatment with volumetric replacement and prescription of hemostatic substances. In some specific cases with more intense and prolonged bleeding, surgical treatment may be necessary. The objective of this chapter is to describe the main evidence on the treatment of women with abnormal uterine bleeding, both acute and chronic. Didactically, the treatment options were based on the current International Federation of Gynecology and Obstetrics (FIGO) classification system (PALM-COEIN). The etiologies of PALM-COEIN are: uterine Polyp (P), Adenomyosis (A), Leiomyoma (L), precursor and Malignant lesions of the uterine body (M), Coagulopathies (C), Ovulatory dysfunction (O), Endometrial dysfunction (E), Iatrogenic (I), and Not yet classified (N). The articles were selected according to the recommendation grades of the PubMed, Cochrane and Embase databases, and those in which the main objective was the reduction of uterine menstrual bleeding were included. Only studies written in English were included. All editorial or complete papers that were not consistent with abnormal uterine bleeding, or studies in animal models, were excluded. The main objective of the treatment is the reduction of menstrual flow and morbidity and the improvement of quality of life. It is important to emphasize that the treatment in the acute phase aims to hemodynamically stabilize the patient and stop excessive bleeding, while the treatment in the chronic phase is based on correcting menstrual dysfunction according to its etiology and clinical manifestations. The treatment may be surgical or pharmacological, and the latter is based mainly on hormonal therapy, anti-inflammatory drugs and antifibrinolytics. Thieme Revinter Publicações Ltda Rio de Janeiro

    Summary Background Uterine lipoleiomyoma is a rare and specific type of leiomyoma. Case Report A 60-year-old postmenopausal woman presented with abdominal pain. Her pelvic ultrasound demonstrated a normal- sized uterus with a well- circumscribed, heterogeneous mass located in the anterior corpus. A pelvic MRI revealed a mass including hyperintense areas on T1-weighted images and hypointense on fat-suppressed T1-weighted images, compatible with lipoleiomyoma. Conclusions Uterine lipoleiomyomas are often misdiagnosed pre-operatively and it is important to distinguish leiomyomas from other tumors for prevention from supererogatory surgery. Imaging plays an important role for the exact differentiation. PMID:26445626

    The present study was carried out to investigate the relationship between creatinine and calcium concentration in buffalo serum in cases of uterine torsion before rolling, and 1 h and 24 h after calving. The degree, duration and site of uterine torsion, as well as fetus viability, time needed for cervical dilation, and the occurrence of uterine rupture were recorded. A total of 150 pregnant buffaloes suffering from colic and anorexia were brought to our clinic and clinically examined. Of these, 35 buffaloes were diagnosed with uterine torsion (different durations, directions and degrees) and the viability of the foeti and any evidence of uterine rupture were determined using ultrasonography and the serum levels of creatinine and calcium were estimated using calorimetric method. The animals were also examined for incidence of uterine rupture after rolling and calving. The calcium level significantly (P < 0.05) decreased with increasing duration and severity of uterine torsion, however, it was higher in cases where a live fetus was delivered compared with a dead one. Conversely, the creatinine level significantly (P < 0.05) increased with increasing duration and severity of uterine torsion but was lower in cases that delivered a live fetus compared with a dead one. The calcium and creatinine levels returned to approximately normal concentration within 24 h after calving. In conclusion, calcium and creatinine serum concentration have a correlation with duration and severity of uterine torsion. Animals with low levels of calcium (below 8.44 mg/dL) and high levels of creatinine (above 2.25 mg/dL) did not usually respond to rolling or suffer from uterine rupture during calving. The calcium and creatinine levels can be used as indicators for the prognosis of mechanical treatment of uterine torsion in buffaloes. Copyright © 2012 Elsevier Inc. All rights reserved.

The authors described a 5-year-old girl with congenital afibrinogenemia who presented with nonketotic hyperosmolar coma associated with spontaneous splenic rupture. Management consisted of correction of the nonketotic hyperosmolar condition and increasing fibrinogen concentration by blood products, followed by splenectomy, resulting in the survival of the patient.

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

    To assess histological changes and possible differences in the quadriceps of patients undergoing open repair of the tendon after spontaneous rupture, and subjects with no history of tendon pathology. Biopsies were harvested from the quadriceps tendon of 46 patients (34 men, 12 women) who had reported unilateral atraumatic quadriceps tendon rupture and had undergone surgical repair of the tendon. Samples were also harvested from both the tendons in 11 (N = 11 × 2) patients, nine males and two females, dying from cardiovascular disorders. For each tendon, three slides were randomly selected and examined under light microscopy, and assessed using a semiquantitative grading scale (range 0-21) which considers fibre structure, fibre arrangement, rounding of the nuclei, regional variations in cellularity, increased vascularity, decreased collagen stainability, and hyalinisation. The pathological sum-score averaged 19.2 ± 3.7 in ruptured tendons and 5.6 ± 2.0 in controls, and all variables considered were significantly different between the two groups, showing an association between tendon abnormalities and rupture (0.05 < P < 0.001). This study confirms that the presence of histological degenerative changes in torn quadriceps tendons increases the risk of rupture.

    Pyometra is collection of purulent material which occurs when there is interference with its normal drainage. It is an uncommon condition with incidence of 0.1 to 0.5% of all gynecological patients. Spontaneous rupture of uterus is an extremely rare complication of pyometra. A 65-year-old lady presented with pain abdomen and purulent vaginal discharge. Preoperative diagnosis of pyometra was made by magnetic resonance imaging (MRI). Laparotomy followed by peritoneal lavage and repair of perforation was performed. Although spontaneously perforated pyometra is rare, the condition must be borne in mind with regard to elderly women with acute abdominal pain. Preoperative diagnosis of perforated pyometra is absolutely essential. Computed tomography (CT) and MRI are diagnostic tools. In selected cases conservative approach at surgery can be opted.

    A systematic review and metaanalysis were performed through electronic database searches to estimate the effect of uterine closure at cesarean on the risk of adverse maternal outcome and on uterine scar evaluated by ultrasound. Randomized controlled trials, which compared single vs double layers and locking vs unlocking sutures for uterine closure of low transverse cesarean, were included. Outcomes were short-term complications (endometritis, wound infection, maternal infectious morbidity, blood transfusion, duration of surgical procedure, length of hospital stay, mean blood loss), uterine rupture or dehiscence at next pregnancy, and uterine scar evaluation by ultrasound. Twenty of 1278 citations were included in the analysis. We found that all types of closure were comparable for short-term maternal outcomes, except for single-layer closure, which had shorter operative time (-6.1 minutes; 95% confidence interval [CI], -8.7 to -3.4; P < .001) than double-layer closure. Single layer (-2.6 mm; 95% CI, -3.1 to -2.1; P < .001) and locked first layer (mean difference, -2.5 mm; 95% CI, -3.2 to -1.8; P < .001) were associated with lower residual myometrial thickness. Two studies reported no significant difference between single- vs double-layer closure for uterine dehiscence (relative risk, 1.86; 95% CI, 0.44-7.90; P = .40) or uterine rupture (no case). In conclusion, current evidence based on randomized trials does not support a specific type of uterine closure for optimal maternal outcomes and is insufficient to conclude about the risk of uterine rupture. Single-layer closure and locked first layer are possibly coupled with thinner residual myometrium thickness. Copyright © 2014 Elsevier Inc. All rights reserved.

    Embolization has become a first-line treatment for symptomatic uterine fibroid tumors. Selective catheterization and embolization of both uterine arteries, which are the predominant source of blood flow to fibroid tumors in most cases, is the cornerstone of treatment. Although embolization for treatment of uterine fibroid tumors is widely accepted, great familiarity with the normal and variant pelvic arterial anatomy is needed to ensure the safety and success of the procedure. The uterine artery classically arises as a first or second branch of the anterior division of the internal iliac artery and is usually dilated in the presence of a uterine fibroid tumor. Angiography is used for comprehensive pretreatment assessment of the pelvic arterial anatomy; for noninvasive evaluation, Doppler ultrasonography, contrast material-enhanced magnetic resonance (MR) imaging, and MR angiography also may be used. After the uterine artery is identified, selective catheterization should be performed distal to its cervicovaginal branch. For targeted embolization of the perifibroid arterial plexus, injection of particles with diameters larger than 500 mum is generally recommended. Excessive embolization may injure normal myometrium, ovaries, or fallopian tubes and lead to uterine necrosis or infection or to ovarian failure. Incomplete treatment or additional blood supply to the tumor (eg, via an ovarian artery) may result in clinical failure. The common postembolization angiographic end point is occlusion of the uterine arterial branches to the fibroid tumor while antegrade flow is maintained in the main uterine artery.

    Embryo transfer (ET) is the last manual intervention after extracorporeal fertilization. After the ET procedure is completed, the embryos are conveyed in the uterus for another two to four days due to spontaneous uterine peristalsis until the window time for implantation. The role of intrauterine fluid flow patterns in transporting the embryos to their implantation site during and after ET was simulated by injection of a liquid bolus into a two-dimensional liquid-filled channel with a closed fundal end via a liquid-filled catheter inserted in the channel. Numerical experiments revealed that the intrauterine fluid field and the embryos transport pattern were strongly affected by the closed fundal end. The embryos re-circulated in small loops around the vicinity where they were deposited from the catheter. The transport pattern was controlled by the uterine peristalsis factors, such as amplitude and frequency of the uterine walls motility, as well as the synchronization between the onset of catheter discharge and uterine peristalsis. The outcome of ET was also dependent on operating parameters such as placement of the catheter tip within the uterine cavity and the delivery speed of the catheter load. In conclusion, this modeling study highlighted important parameters that should be considered during ET procedures in order to increase the potential for pregnancy success.

    Recent experience has convinced the author of the value of ovarian grafting. He gives the histories of a number of women upon whom he made implants of their own ovarian tissue in the course of operations for double oöphorectomy. The subsequent state of these patients is contrasted with that of women after castration without grafting. When the uterus was left in position menstruation was re-established in over 80% of the grafted cases. The author and his co-workers maintain that the vitality of autogenous grafts of ovarian substance is enhanced by hormones produced by the uterine mucosa. He therefore advocates that grafts of uterus be made in conjunction with ovarian implants whenever possible. Experiments carried out on animals have proved the correctness of this opinion. The results of a series of cases of combined ovarian and uterine graftings are recorded, and the technique of uterine mucosa implants is described.

    This overview focuses on the follow up after uterine cervix and corpus cancers. At early stage, both are associated with good prognosis. Screening for recurrence is mainly based on clinical examination. Screening for a second cancer after endometrial cancer is already planned according to the French recommendations for systematic breast and colon cancer screening. Screening for a second cancer after cervical cancer requires a close examination of organs close to the cervix receiving high doses of radiations and HPV exposed (anus, vulva, vagina and perineum). Late chemotherapy related toxicity after both cancers is rarely encountered and mainly comprise neurological peripheral effects. Late surgical and/or radiation related side effects are more frequent. However, no more than 10% of patients are affected and in such cases, digestive, urinary and lymphatic systems are impaired. Prevalence of sexual dysfunction in patients with uterine cancers is particularly high but the radiotherapy related anatomical modifications (vaginal stenosis for example) might not be the sole reason. Fertility preservation is possible for uterine cancers but requires a rigorous selection of candidates and should be coordinated by specialized team.

Figures are the bulk of the document, with 3 figures demonstrating the type of operation, 3 showing the scheme of the operation, 1 figure showing a posterior view of the implanted tube in utero with a polyethylene prosthesis in situ down to the cervix, and 1 figure showing the instruments used in the operation. A few points of experience the author shares are: 1) operate immediately after a menstrual period; 2) give antibiotics prophylactically and after the procedure; 3) use a Bonney Myomectomy Clamp to elevate the uterus; 4) never use a knife or bistoury at the cornua; 5) use polyethylene rods, when available; and 6) caesarean section is the indicated delivery route after tubo-uterine implantation. Out of 38 patients with the requisite history and findings who have been operated on by this author, 14 have gone to full-term, i.e., 36.1%; 2 have aborted, giving a pregnancy rate of 42.2%, and there was 1 ectopic pregnancy.

    Management of tracheal ruptures in critically ill patients is challenging. Conservative treatment has been described, but in mechanically ventilated patients with distal tracheal ruptures surgical repair might be inevitable. Strategies for diagnosis and treatment of tracheal ruptures and handling of mechanical ventilation remain to be clarified. Our aim was to comprise a structured diagnostic and treatment protocol for patients suspicious of tracheal injury, including detailed principles of mechanical ventilation and specific indications for conservative or surgical treatment. Patients with tracheal ruptures were compared in accordance to the need of mechanical ventilation and to indication for surgical repair. In patients suffering from tracheal ruptures affecting the whole tracheal wall and with protrusion of mediastinal structures into the lumen surgery was indicated. We compared ventilatory, hemodynamic and clinical parameters between the different patient groups. We report our structured approach in diagnostics and treatment of tracheal ruptures and place special emphasis on respiratory management. Seventeen patients with tracheal rupture were identified. In 8 patients surgical repair was performed 1.8±1.5 days after diagnosis. Previous to surgery, ventilation parameters improved significantly: plateau pressure decreased, percentage of assisted spontaneous breathing increased and compliance improved. Conservative treatment was successful in long-term ventilated patients (13.7±8 days) even when suffering from distal lesions. Invasiveness of mechanical ventilation and obstruction of tracheal lumen might indicate conservative or surgical treatment strategies in long-term ventilated patients suffering from iatrogenic tracheal rupture. Indications for surgical repair remain to be further clarified.

    Interstitial pregnancy is a rare and dangerous form of ectopic pregnancy which is treated by surgery, medical treatment, or both. Management options are not standardized. Currently, conservative nonsurgical treatment seems to be an alternative method in case of interstitial pregnancy. A right interstitial pregnancy was diagnosed in a 28-year-old woman. She was successfully treated by 2 courses of systemic methotrexate (1 mg/kg) 24 hours apart followed by selective uterine artery embolization. The postembolization course was uneventful, and no rupture occurred. Ten weeks after embolization, human chorionic gonadotropin level was negative. Uterine embolization associated with methotrexate can be used successfully in treating selected cases of early interstitial pregnancy. We hypothesize that this procedure combined with methotrexate could reduce hemorrhagic risk.

    Intracranial dermoid cysts are rare tumors derived from ectopic epithelial cells. They are slow-growing benign entities, but can cause significant morbidity through compression of neurovascular structures and, rarely, rupture into the subarachnoid space. We present a rare case of a spontaneously ruptured intracranial dermoid cyst presenting as new onset seizures due to chemical meningitis caused by dissemination of fat droplets.

    The uterine tetanic contraction and uterine artery blood flow reduction are possible reasons for primary dysmenorrhea (PD). In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction (GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F2 alpha (PGF2α) and Ca(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF2α and Ca(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy.

    Uterine fibroid is a benign tumour of uterine smooth muscle. The purpose of this review is to bring to light the current spectra of presentation and management status of this benign and very important cause of menstrual and fertility disturbance in African women and the Black race in general. This is especially so with the trivialization of its aetological factors and treatment by claims from alternative medical practitioners. This review, therefore sought to document what is currently known about the condition and what could possibly be done to achieve better results in its management. Literature on the subject above was reviewed using manual library search, electronic books such as CD-ROMS and journals articles published by various local and international authors on the subject; it also included internet search on relevant aspects of the topic. Fibroid is the commonest benign tumour of the female genital tract, it contributes about 70 to 80% of new growths in the female genital tracts, it is a cause of significant morbidity in women of reproductive age group and when complicated could be a significant cause of mortality. Spectrum of presentation mainly involves disturbance of menstruation, reduction in fertility, pressure and obstructive symptoms and rarely malignant presentations. When recognized early effective conservative and definitive therapies are available to offer relief for women and to make their menstrual and reproductive life more meaningful. From the literature reviewed, it was obvious that the subject of uterine fibroid is still not fully exhausted and there were a lot of research questions waiting to be answered on the aetiopathogenesis of the disease. There is also the need to fashion out better treatment alternatives that will reduce morbidity in the process of managing the patient as well as those that will further enhance reproductive potentials after treatment.

  8. 3D Dynamic Crack Rupture by a Finite Volume Method

    Dynamic rupture of a 3D spontaneous crack of arbitrary shape has been investigated using a Finite Volume (FV) approach. The full domain is decomposed in tetrahedra while the surface on which the rupture is supposed to take place is discretized with triangles which are faces of tetrahedra. Because of this meshing strategy, any shape of the rupture surface could be designed and is performed once before simulations start. First of all, the elastodynamic equations are described into a pseudo-conservative form for easy application of the FV discretisation. Explicit boundary conditions are given using criteria based on the conservation of discrete energy through the crack surface. Using a stress-threshold criterion, these conditions specify fluxes through those triangles which have suffered rupture. On these broken surfaces, stress follows A linear slip-weakening law although other friction laws can be implemented as well. Numerical solutions on a planar fault are achieved for the problem version 3 of the SCEC community dynamic-rupture benchmark exercise (Harris and Archuleta, 2004) and compared with those provided by a Finite Difference (FD) technique (Day et al, 2005). Another benchmark problem is also tackled involving a nonplanar curved fault (Cruz-Atienza et al, 2007). Solutions for this difficult exercise are compared with those computed with a Boundary Integral (BI) method (Aochi et al, 2000). In both benchmarck problems, comparisons show that rupture fronts are well modelled with a slight delay in time especially along the antiplane direction related to the low-order interpolation of the FV approach which requires further mesh refinement or/and an higher-order interpolation strategy as for Galerkin Discontinuous approach. Slip-rate and shear stress amplitudes are well modelled as well as stopping phases and stress overshoots. We expect this method, which is well adapted to multi-preocessor parallel computing to be competitive with others for solving large scale

    Subcapsular hematoma and/or rupture of the graft is uncommon but serious complication of liver transplantation. It may develop spontaneously or following parenchymal injuries or percutaneous transhepatic invasive procedures. This report describes three cases of subcapsular hematoma and/or rupture of the graft with different courses among 350 liver transplantations. In the first case, the patient died due to graft rupture caused by a pseudoaneurysm after biopsy. In the second case, a small injury of the donor liver resulted in a deep rupture, which required partial resection of the graft. The patient died in sepsis later. The third patient presented with a large subcapsular haematoma during transplantation, which was successfully treated. The authors' strategies developed intraoperatively for the management of hematomas. These involve opening and removing of the haematoma, haemostasis with Argon coagulation, which resulted in an adherent Glisson's capsule to the parenchyma and covering with collagen fleece coated with fibrinogen and thrombin.

  10. Biomechanical Rupture Risk Assessment

    PubMed Central

    2016-01-01

    Abdominal aortic aneurysm (AAA) rupture is a local event in the aneurysm wall that naturally demands tools to assess the risk for local wall rupture. Consequently, global parameters like the maximum diameter and its expansion over time can only give very rough risk indications; therefore, they frequently fail to predict individual risk for AAA rupture. In contrast, the Biomechanical Rupture Risk Assessment (BRRA) method investigates the wall’s risk for local rupture by quantitatively integrating many known AAA rupture risk factors like female sex, large relative expansion, intraluminal thrombus-related wall weakening, and high blood pressure. The BRRA method is almost 20 years old and has progressed considerably in recent years, it can now potentially enrich the diameter indication for AAA repair. The present paper reviews the current state of the BRRA method by summarizing its key underlying concepts (i.e., geometry modeling, biomechanical simulation, and result interpretation). Specifically, the validity of the underlying model assumptions is critically disused in relation to the intended simulation objective (i.e., a clinical AAA rupture risk assessment). Next, reported clinical BRRA validation studies are summarized, and their clinical relevance is reviewed. The BRRA method is a generic, biomechanics-based approach that provides several interfaces to incorporate information from different research disciplines. As an example, the final section of this review suggests integrating growth aspects to (potentially) further improve BRRA sensitivity and specificity. Despite the fact that no prospective validation studies are reported, a significant and still growing body of validation evidence suggests integrating the BRRA method into the clinical decision-making process (i.e., enriching diameter-based decision-making in AAA patient treatment).

    Context: Achilles tendon (AT) rupture in athletes is increasing in incidence and accounts for one of the most devastating sports injuries because of the threat to alter or end a career. Despite the magnitude of this injury, reliable risk assessment has not been clearly defined, and prevention strategies have been limited. The purpose of this review is to identify potential intrinsic and extrinsic risk factors for AT rupture in aerial and ground athletes stated in the current literature. Evidence Acquisition: A MEDLINE search was conducted on AT rupture, or “injury” and “risk factors” and “athletes” from 1980 to 2011. Emphasis was placed on epidemiology, etiology, and review articles focusing on the risk for lower extremity injury in runners and gymnasts. Thirty articles were reviewed, and 22 were included in this assessment. Results: Aerial and ground athletes share many intrinsic risk factors for AT rupture, including overuse and degeneration of the tendon as well as anatomical variations that mechanically put an athlete at risk. Older athletes, athletes atypical in size for their sport, high tensile loads, leg dominance, and fatigue also may increase risk. Aerial athletes tend to have more extrinsic factors that play a role in this injury due to the varying landing surfaces from heights and technical maneuvers performed at various skill levels. Conclusion: Risk assessment for AT rupture in aerial and ground athletes is multivariable and difficult in terms of developing prevention strategies. Quantitative measures of individual risk factors may help identify major contributors to injury. PMID:24427410

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

    The behavior of lipid vesicles near solid surfaces, despite its scientific and technological significance, is poorly understood. By simultaneously taking into account (i) the dynamics of spontaneous pore opening and closing in surface bound vesicles; (ii) their volume loss via leakage through the pores; (iii) and the propagation of their contact line, we have developed a simple model that can fully describe the detailed mechanism of and provide the necessary conditions for the rupture of vesicles and the subsequent formation of supported lipid bilayers. The predictions of the model are in qualitative agreement with many of the experimental observations.

    The first attempt to discover spontaneous fission in uranium was made by [Willard] Libby, who, however, failed to detect it on account of the smallness of effect. In 1940, [K. A.] Petrzhak and [G. N.] Flerov, using more sensitive methods, discovered spontaneous fission in uranium and gave some rough estimates of the spontaneous fission decay constant of this substance. Subsequently, extensive experimental work on the subject has been performed by several investigators and will be quoted in the various sections. [N.] Bohr and [A.] Wheeler have given a theory of the effect based on the usual ideas of penetration of potential barriers. On this project spontaneous fission has been studied for the past several years in an effort to obtain a complete picture of the phenomenon. For this purpose the spontaneous fission decay constants {lambda} have been measured for separated isotopes of the heavy elements wherever possible. Moreover, the number {nu} of neutrons emitted per fission has been measured wherever feasible, and other characteristics of the spontaneous fission process have been studied. This report summarizes the spontaneous fission work done at Los Alamos up to January 1, 1945. A chronological record of the work is contained in the Los Alamos monthly reports.

    Numerical simulations of earthquake rupture dynamics are now common, yet it has been difficult to test the validity of these simulations because there have been few field observations and no analytic solutions with which to compare the results. This paper describes the Southern California Earthquake Center/U.S. Geological Survey (SCEC/USGS) Dynamic Earthquake Rupture Code Verification Exercise, where codes that simulate spontaneous rupture dynamics in three dimensions are evaluated and the results produced by these codes are compared using Web-based tools. This is the first time that a broad and rigorous examination of numerous spontaneous rupture codes has been performed—a significant advance in this science. The automated process developed to attain this achievement provides for a future where testing of codes is easily accomplished.Scientists who use computer simulations to understand earthquakes utilize a range of techniques. Most of these assume that earthquakes are caused by slip at depth on faults in the Earth, but hereafter the strategies vary. Among the methods used in earthquake mechanics studies are kinematic approaches and dynamic approaches.The kinematic approach uses a computer code that prescribes the spatial and temporal evolution of slip on the causative fault (or faults). These types of simulations are very helpful, especially since they can be used in seismic data inversions to relate the ground motions recorded in the field to slip on the fault(s) at depth. However, these kinematic solutions generally provide no insight into the physics driving the fault slip or information about why the involved fault(s) slipped that much (or that little). In other words, these kinematic solutions may lack information about the physical dynamics of earthquake rupture that will be most helpful in forecasting future events.To help address this issue, some researchers use computer codes to numerically simulate earthquakes and construct dynamic, spontaneous

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

    The growth of a ruptured small saccular aneurysm has rarely been documented. Also rare are reports of spontaneous thrombosis of ruptured small intracranial saccular aneurysms. However, there are no reported instances of ruptured small saccular aneurysms that have demonstrated an increase in size after rupture, subsequently thrombosed and disappeared from circulation. We report one such aneurysm in a patient who presented with subarachnoid hemorrhage from a ruptured small saccular aneurysm of the anterior communicating artery. The possible reasons for the initial growth and subsequent thrombosis of the aneurysm from morphometric and flow dynamic points of view are discussed.

    To define the different stages of spontaneous labour. To determine the indications, modalities of use and the effects of administering synthetic oxytocin. And to describe undesirable maternal and perinatal outcomes associated with the use of synthetic oxytocin. A systematic review was carried out by searching Medline database and websites of obstetrics learned societies until March 2016. The 1st stage of labor is divided in a latence phase and an active phase, which switch at 5cm of cervical dilatation. Rate of cervical dilatation is considered as abnormal below 1cm per 4hour during the first part of the active phase, and below 1cm per 2hours above 7cm of dilatation. During the latent phase of the first stage of labor, i.e. before 5cm of cervical dilatation, it is recommended that an amniotomy not be performed routinely and not to use oxytocin systematically. It is not recommended to expect the active phase of labor to start the epidural analgesia if patient requires it. If early epidural analgesia was performed, the administration of oxytocin must not be systematic. If dystocia during the active phase, an amniotomy is recommended in first-line treatment. In the absence of an improvement within an hour, oxytocin should be administrated. However, in the case of an extension of the second stage beyond 2hours, it is recommended to administer oxytocin to correct a lack of progress of the presentation. If dynamic dystocia, it is recommended to start initial doses of oxytocin at 2mUI/min, to respect at least 30min intervals between increases in oxytocin doses delivered, and to increase oxytocin doses by 2mUI/min intervals without surpassing a maximum IV flow rate of 20mUI/min. The reported maternal adverse effects concern uterine hyperstimulation, uterine rupture and post-partum haemorrhage, and those of neonatal adverse effects concern foetal heart rate anomalies associated with uterine hyperstimulation, neonatal morbidity and mortality, neonatal jaundice, weak suck

    Visceral artery aneurysms are rare but their estimated mortality due to rupture ranges between 25 and 70%. Treatment of visceral artery aneurysm rupture is usually managed by interventional radiology. Specific embolization techniques depend on the location, affected organ, locoregional arterial anatomy, and interventional radiologist skill. The success rate following treatment by interventional radiology is greater than 90%. The main complication is recanalization of the aneurysm, showing the importance of post-therapeutic monitoring, which should preferably be performed using MR imaging.

    Uterine contractile activity in nonpregnant conscious dogs was investigated based on 2- to 6-mo-long continuous recording by means of a chronically implanted force transducer. We found that nonpregnant uterine contractile activity could be classified into six major patterns: sporadic contractions, weak and strong tonic contractions, weak and strong phasic contractions, and phasic contraction bursts. The contractile patterns during proestrus and estrus were the most active, with strong phasic and tonic contractions and phasic contraction bursts. The phasic and tonic contractions were inhibited dose-dependently by a beta 2 adrenergic agonist, ritodrine, and reproduced by an alpha 2 adrenergic agonist, clonidine. In contrast, the cholinergic inhibitors atropine and hexamethonium did not affect the spontaneous occurrence of these contractions, although bethanechol evoked uterine contractions. Oxytocin and prostaglandin F2 alpha-induced contractions were phasic during estrus, whereas they showed tonic increases with phasic contractions during proestrus, diestrus, and anestrus, and these contractions did not resemble the spontaneous contractions. In conclusion, the nonpregnant uterus contracts continuously in harmony with the estrous cycle phases, and its contractile activity is enhanced by alpha adrenergic receptors and inhibited by beta 2 adrenergic receptors.

    Presentation of uterine prolapse is a rare event in a pregnant woman, which can be pre-existent or else manifest in the course of pregnancy. Complications resulting from prolapse of the uterus in pregnancy vary from minor cervical infection to spontaneous abortion, and include preterm labor and maternal and fetal mortality as well as acute urinary retention and urinary tract infection. Moreover, affected women may be at particular risk of dystocia during labor that could necessitate emergency intervention for delivery. Recommendations regarding the management of this infrequent but potentially harmful condition are scarce and outdated. This review will examine the causative factors of uterine prolapse and the antepartum, intrapartum and puerperal complications that may arise from this condition as well as therapeutic options available to the obstetrician. While early recognition and appropriate prenatal management of uterine prolapse during pregnancy is imperative, implementation of conservative treatment modalities throughout pregnancy, these applied in accordance with the severity of the uterus prolapse and the patient's preference, may be sufficient to achieve uneventful pregnancy and normal, spontaneous delivery.

    To evaluate the effects of epidural analgesia on uterine artery, umbilical, and fetal cerebral Doppler velocities during labor. In a prospective study at Beaujon Hospital, Paris, France, between September and December 2010, uterine artery, umbilical, and fetal cerebral Doppler flow velocities were measured in 12 pregnant women during spontaneous labor with epidural analgesia. The data were registered in a period of uterine relaxation before, and 20 and 60 minutes after the first administration of epidural analgesic drugs. The changes in Doppler velocimetry values and fetal heart rate after epidural analgesia were analyzed. Uterine artery velocities, but neither umbilical nor fetal cerebral Doppler velocities, were decreased significantly at 20 minutes and 1 hour after epidural analgesia (P<0.005). Women with the greatest decrease in uterine artery Doppler flow velocities delivered neonates with the lowest values of umbilical artery blood pH. The data suggest that the Doppler flow velocity of uterine arteries is affected by epidural analgesia during labor. Numerous Doppler flow studies of the effect of neuraxial blockade during labor on umbilical and uterine arteries have been published with incredibly variable and inconsistent results.

    To investigate the efficiency and safety of transcatheter uterine artery embolization (TUAE) for uterine myomas. Thirty-eight cases of uterine myomas were treated by TUAE using lipiodol-pingyangmycin emulsion. 5 of 38 cases underwent hysterectomy or myomectomy from 1 to 3 weeks after TUAE. The specimens were studied pathologically. Thirty-three of 38 patients were followed for 3 to 6 months to observe the changes of myoma size and uterine volume and overian function. Symptom released in 90.6% (29/32), that was controlled of menorrhagia in 90.3% (28/31), disappeared of lumbago and lower abdominal pain in 83.3% (25/30), relieved of freguency and urgency of micturition in 45.5% (5/11). The mean reduction of myoma and uterine volume at 6 months was 59.1% and 49.3%, respectively, and at 12 months was 61.8% and 49.9% respectively. There was no significant difference in hormone level pre-embolization and post-embolization. Pathological studies of specimens showed that lipiodol deposition was found in myomas but not in myometrium. Myomas occurred spotty necrosis 2 weeks after embolization and extensive patchy necrosis 3 weeks after embolization. Degeneration or necrosis were not seen in myometrium. TUAE possesses a good effect for uterine myomas and doesn't result in the damage of ovarian hormone secretion and the myometrium.

    2014-01-01

    Metastases to the female genital tract are rare, with metastatic disease restricted to the uterus being even less frequent. The primary tumor is most often intragenital rather than extragenital. The diagnosis is usually made after occurrence of gynecological symptoms. We describe the case of a 26-year-old female, in whom a curettage for menorrhagia revealed a uterine malignancy, at first thought to be a carcinosarcoma. Biochemistry only showed iron deficiency anemia. Imaging showed discrepant results with liver lesions, suspect of neoplastic or inflammatory disease. She underwent an abdominal hysterectomy and, peroperatively, a frozen section of a mass in the liver hilus demonstrated a cholangiocarcinoma. The diagnosis of a uterine metastasized cholangiocarcinoma was made. We emphasize the fact that uterine metastases have to be excluded in every woman with abnormal uterine bleeding and a personal history of malignancy. However, our case also indicates that gynecological metastatic disease may be the first presentation of an extragenital primary neoplasm. PMID:25610676

  12. Surgical treatment of uterine sarcoma.

    Uterine sarcomas are rare, heterogeneous malignant tumours of several histologic types originating from mesenchymal tissues of the uterus. The most common histologic types are carcinosarcoma, leiomyosarcoma, and endometrial stromal sarcoma, accounting for 90% of uterine sarcomas. To date, no effective treatment has been found to achieve a high rate of cure or prolong survival. Although complete surgical excision of the tumour is the only curative treatment modality, the rarity of these tumours and their diversity of histologic types have precluded the development of standard surgical strategies. Surgery may also be optimal for recurrent uterine sarcomas, but indications for secondary surgical treatment have not been established. Here, we describe recent changes in, and updates of, the surgical treatment of the three most common types of malignant uterine sarcomas.

Instead, much of former investigation in seismology evaluated earthquake characteristics in terms of kinematics that does not directly treat such dynamic aspects and usually excludes the influence of high-frequency wave components over 1 Hz.

    The aim of the work was to compare labour courses, ways of delivery, condition of the newborns in spontaneous and oxytocin-related labours and to analyse the indications for oxytocin administration. 2198 full-term deliveries (pregnant women qualified for elective caesarean section were excluded from the study) at the Provincial Hospital in Przemyśl, Poland. Labours with the adjunctive oxytocin infusion--1102 women. spontaneous labours (without oxytocin administration)--1096 women. The analysis of the compatibility of measured traits was carried out by the Chi2 test, p < 0.05 was assumed as statistically significant level. I. Indications for the oxytocin administration: secondary hypokinetic contractions of the uterus (642 labours--58.25%), premature rupture of membranes (176 labours - 15.97 %). II. Deliveries by caesarean section: 1. study group--187 women (16.97%). 2. control group--97 women (8.85%). Ch2 = 32.192; df = 1; p = 0.0000. III. Newborns after vaginal labours scored 7 or below according to the Apgar in the first minute after the delivery. 1. study group--35 newborns (8.7%); 2. control group--18 newborns (1.8%) ch2 = 5.493; df = 1; p = 0.0190. IV. Newborns hospitalised for over 48 hours: 1. study group--346 (31.39%); 2. control group--216 newborns (19.70%). Chi2 = 39.454; df = 1; p = 0.0000. (1) Hypokinetic uterine contractions were the most frequent indication for oxytocin administration during labour. (2) Oxytocin administration increases twice the risk of delivery by the caesarean section. (3) Newborns after vaginal oxytocin-related labours scored 7 or below on the Apgar score in the first minute after the birth when compared to the newborns after spontaneous labour. (4) Oxytocin administration during parturition elongates the time of newborns hospitalisation.

    Traditionally, vaginal hysterectomy and Manchester repair were the surgical approaches to treating uterine prolapse; however, both are associated with a relatively high subsequent vaginal vault recurrence. Laparoscopic uterine suspension is a new way of maintaining uterine support. Many women are keen to keep their uterus for a variety of reasons, including maintaining reproductive capability and the belief that the uterus, cervix, or both, may play a part of their gender identity. Non-removal of the uterus may retain functional (e.g. bowel, bladder and sexual) benefits. Therefore, the concept of uterine preservation for pelvic-organ prolapse has been of interest to pelvic-floor surgeons for many decades. In this review, we provide an overview of the available evidence on treating uterine prolapse surgically. We describe techniques to support the vault during hysterectomy, and examine the evidence for uterine-sparing surgery. Comparative outcomes for vaginal, abdominal and laparoscopic routes will be made. Copyright © 2012 Elsevier Ltd. All rights reserved.

  18. Postpartum uterine health in cattle.

    PubMed

    Sheldon, I M; Dobson, H

    2004-07-01

    Uterine health is often compromised in cattle because postpartum contamination of the uterine lumen by bacteria is ubiquitous, and pathogenic bacteria frequently persist causing clinical disease. The subfertility associated with uterine infection involves perturbation of the hypothalamus, pituitary and ovary, in addition to the direct effects on the uterus, and appears to persist even after clinical resolution of the disease. Absorption of bacterial components from the uterus can prevent the follicular phase LH surge and ovulation. In addition, the first postpartum dominant follicle has a slower growth rate and secretes less estradiol at the end of the growth phase. There are also localised ovarian effects of high uterine bacterial growth density, because fewer first dominant follicles are selected in the ovary ipsilateral than contralateral to the previously gravid uterine horn. Thus, it is important to diagnose and treat uterine disease promptly and effectively. Examination of the contents of the vagina for the presence of pus is the most useful method for diagnosis of endometritis. The character and odor of the vaginal mucus can be scored and this endometritis score is correlated with the growth density of pathogenic bacteria in the uterus, and is prognostic for the likely success of treatment. The challenge for the future is to design prevention and control programs to reduce the incidence of disease, and understand how the immune and endocrine systems are integrated.

  19. Rupture of lenticulostriate artery aneurysms.

    2014-02-01

    The authors report on 3 rare cases of ruptured lenticulostriate artery (LSA) aneurysms that were heralded by deep cerebral hematomas. The hematomas were unilateral in 2 cases and bilateral in 1; in the bilateral case, only a single LSA aneurysm could be identified on the right side of the brain. Because of their small size (≤ 2 mm), fusiform aspect, and deep location within the brain, all of the aneurysms were treated conservatively. There was no hemorrhage recurrence, and follow-up angiography demonstrated spontaneous thrombosis in 2 of the 3 cases. The clinical course was favorable in 2 of the 3 patients. The course in the patient with the bilateral hematoma was marked by an ischemic event after the initial episode, resulting in an aggravation of deficits. The cause of this second event was uncertain. Because our knowledge about the natural history of LSA aneurysms is incomplete, there is no consensus concerning a therapeutic strategy. The authors' experience in 3 reported cases leads them to think that a conservative approach involving close angiographic monitoring may be proposed as first-line treatment. If the monitored aneurysm then persists or grows in size, its occlusion should be considered. Nonetheless, other studies are needed to further strengthen the legitimacy of this strategy.

  20. Preoperative 3-dimensional Magnetic Resonance Imaging of Uterine Myoma and Endometrium Before Myomectomy.

    Uterine myomas are the most common gynecologic benign tumor affecting women of childbearing age, and myomectomy is the main surgical option to preserve the uterus and fertility. During myomectomy for women with multiple myomas, it is advisable to identify and remove as many as possible to decrease the risk of future myomectomies. With deficient preoperative imaging, gynecologists are challenged to identify the location and size of myomas and the endometrium, which, in turn, can lead to uterine rupture during future pregnancies. Current conventional 2-dimensional imaging has limitations in identifying precise locations of multiple myomas and the endometrium. In our experience, we preferred to use 3-dimensional imaging to delineate the myomas, endometrium, or blood vessels, which we were able to successfully reconstruct by using the following imaging method. To achieve 3-dimensional imaging, we matched T2 turbo spin echo images to detect uterine myomas and endometria with T1 high-resolution isotropic volume excitation-post images used to detect blood vessels by using an algorithm based on the 3-dimensional region growing method. Then, we produced images of the uterine myomas, endometria, and blood vessels using a 3-dimensional surface rendering method and successfully reconstructed selective 3-dimensional imaging for uterine myomas, endometria, and adjacent blood vessels. A Web-based survey was sent to 66 gynecologists concerning imaging techniques used before myomectomy. Twenty-eight of 36 responding gynecologists answered that the 3-dimensional image produced in the current study is preferred to conventional 2-dimensional magnetic resonance imaging in identifying precise locations of uterine myomas and endometria. The proposed 3-dimensional magnetic resonance imaging method successfully reconstructed uterine myomas, endometria, and adjacent vessels. We propose that this will be a helpful adjunct to uterine myomectomy as a preoperative imaging technique in future

  1. Complete Achilles tendon ruptures.

    1992-10-01

    Achilles tendon ruptures can be treated nonsurgically in the nonathletic or low-end recreational athletic patient, particularly those more than 50 years of age, provided the treating physician does not delay in the diagnosis and treatment (preferably less than 48 hrs and possibly less than 1 week). The patient should be advised of the higher incidence of re-rupture of the tendon when treated nonsurgically. Surgical treatment is recommended for patients who are young and athletic. This is particularly true because the major criticism of surgical treatment has been the complication rate, which has decreased to a low level and to a mild degree, usually not significantly affecting the repair over time. Surgical treatment in these individuals seems to be superior not only in regard to re-rupture but also in assuring the correct apposition of the tendon ends and in placing the necessary tension on the tendon to secure appropriate orientation of the collagen fibers. This in turn allows them to regain full strength, power, endurance, and an early return to sports. Surgery is also recommended for late diagnosed ruptures where there is significant lengthening of the tendon. Surgical technique should involve a medial incision to avoid the sural nerve, absorbable suture, and augmentation with fascia or tendon where there is a gap or late rupture. Postoperatively, the immobilization should be 7 to 10 days in a splint. A walking boot with early motion in plantar flexion or a short leg cast with the tendon under slight tension should thereafter be used for 4 to 5 weeks. An early and well-supervised rehabilitation program should be initiated to restore the patient to the preinjury activity level.

  2. Primary uterine inertia in four labrador bitches.

    PubMed

    Davidson, Autumn P

    2011-01-01

    Uterine inertia is a common cause of dystocia in the bitch and is designated as primary (i.e., uterine contractions fail to ever be initiated) or secondary (i.e., uterine contractions cease after a period of time but before labor is completed). The etiology of primary uterine inertia is not well understood. The accurate diagnosis of primary uterine inertia requires the use of tocodynamometry (uterine monitoring). Primary uterine inertia has been postulated to result from a failure of luteolysis resulting in persistently elevated progesterone concentrations. In this study, primary uterine inertia was diagnosed in a series of four bitches in which luteolysis was documented suggesting some other etiopathogenesis for primary uterine inertia.

    Uterine fibroids or uterine leiomyomas are the most common benign tumors of the uterus among women of fertile age, while the etiology is still incompletely elucidated. The occurrence and development of the fibromatosis may be related to certain risk factors and genic mechanisms, although the exact causes are not yet fully known. The development of uterine fibroids is correlated not only with the metabolism and with the level of female sexual hormones, estrogen, and progesterone, but also with the number of these hormone receptors expressed on the surface of the myometrium. Proliferative effects of estrogen and progesterone may be exercised through proinflammatory factors (TNF alpha), growth factors (IGF1, IGF2, TGFbeta3 and betaFGF) or inhibitors of apoptosis (p53 suppression). A number of predisposing factors such as ethnicity – black skin, early menarche, nulliparity, caffeine and alcohol, chronic inflammation, obesity, were also identified. Approximately 40% of the uterine fibroids are caused by the same cytogenetic alterations found in the other tumor types such as kidney, lung, or leiomyosarcoma. As part of a system dysfunction, uterine fibromatosis was connected to other disorders such as AHT (arterial hypertension), endometrium adenocarcinoma, adenomyosis, endometriosis, diabetes mellitus, breast tumors, seemingly with a common causality. The action and effect of some hormonal imbalances over the various organs depend on the histological and local expression particularities of the various receptors, being the cause for many disorders, among which the uterine fibromatosis, coexisting or accompanying the later. This article examines and summarizes the latest data refreshed literature etiopathogenesis offering indicators of uterine fibroids. PMID:27974911

  6. Fan-structure waves in shear ruptures

    NASA Astrophysics Data System (ADS)

    Tarasov, Boris

    2016-04-01

    This presentation introduces a recently identified shear rupture mechanism providing a paradoxical feature of hard rocks - the possibility of shear rupture propagation through the highly confined intact rock mass at shear stress levels significantly less than frictional strength. According to the fan-mechanism the shear rupture propagation is associated with consecutive creation of small slabs in the fracture tip which, due to rotation caused by shear displacement of the fracture interfaces, form a fan-structure representing the fracture head. The fan-head combines such unique features as: extremely low shear resistance (below the frictional strength), self-sustaining stress intensification in the rupture tip (providing easy formation of new slabs), and self-unbalancing conditions in the fan-head (making the failure process inevitably spontaneous and violent). An important feature of the fan-mechanism is the fact that for the initial formation of the fan-structure an enhanced local shear stress is required, however, after completion of the fan-structure it can propagate as a dynamic wave through intact rock mass at shear stresses below the frictional strength. Paradoxically low shear strength of pristine rocks provided by the fan-mechanism determines the correspondingly low transient strength of the lithosphere, which favours generation of new earthquake faults in the intact rock mass adjoining pre-existing faults in preference to frictional stick-slip instability along these faults. The new approach reveals an alternative role of pre-existing faults in earthquake activity: they represent local stress concentrates in pristine rock adjoining the fault where special conditions for the fan-mechanism nucleation are created, while further dynamic propagation of the new fault (earthquake) occurs at low field stresses even below the frictional strength.

    Abdominal aortic aneurysm (AAA) is a vascular disease that results in the gradual dilation of the abdominal aorta and has a high rupture-related mortality rate. However, the mechanism of AAA rupture remains unknown. In our previous study, we established a novel AAA animal model (hypoperfusion-induced AAA rat model) with spontaneous AAA rupture. Using the hypoperfusion-induced AAA rat model, we demonstrated that the abnormal appearance of adipocytes in the vascular wall is associated with AAA rupture. However, pathological analysis of the rupture area has not been performed because it is particularly difficult to identify the rupture point. In this study, we succeeded in obtaining samples from the rupture point and performed a histological analysis of the ruptured area in the vascular wall in the hypoperfusion-induced AAA rat model. Adipocytes were observed along the AAA-ruptured area of the vascular wall. In the areas around the adipocytes, macrophage infiltration and protein levels of matrix metalloproteinases 2 and 9 were significantly increased and collagen-positive areas were significantly decreased, as compared with areas without adipocytes. The AAA diameter was correlated with the number of adipocytes in the vascular wall of the hypoperfusion-induced AAA rat model. On the other hand, serum triglyceride levels and serum total cholesterol levels were not correlated with the number of adipocytes in the vascular wall. These results suggest that local adipocyte accumulation in the vascular wall, not serum lipids, has an important role in AAA rupture.

    Shunt infections are most common within the first 6 months following implantation. A shunt infection 19 years after implantation secondary to uterine ablation has not been reported to our knowledge. Office hysteroscopic procedures have become commonplace in gynecologic practice. Infectious complication rates are low, but peritonitis has been described. We present a patient with a ventriculoperitoneal shunt infection following a uterine ablation for dysfunctional uterine bleeding. Three days following the ablation she developed abdominal pain. CT scan of the abdomen 5 months after the procedure revealed a pseudocyst. She then underwent removal of her shunt with intra-operative cultures revealing Streptococcus agalactiae. Definitive treatment consisted of shunt explantation and antibiotic treatment with complete resolution of her pain and pseudocyst. Consideration for prophylactic antibiotics should be made when a patient with a ventriculoperitoneal shunt undergoes any transvaginal procedure.

  9. Premature rupture of membranes.

    Poma, P. A.

    1996-01-01

    The management of patients with premature rupture of membranes has changed markedly in the past several years. The basis for this is a combination of a better understanding of newborn physiology, improved neonatal care, refinements in antibiotic therapy, and the widespread use of maternal and fetal monitoring. The best outcome for both mother and infant undoubtedly reflects data based on a combination of factors, among which are gestational age survival, evidence of fetal distress, presence or absence of labor and sepsis, and of course, the cervical condition as it is related to labor-readiness. An important recent advance is the recognition that an active observation management program is associated with less morbidity and mortality than the classic management course of delivery within 12 hours of membrane rupture. The fact that preterm premature rupture of membranes tends to recur in subsequent pregnancies offers an opportunity for prevention. Moreover, advances in perinatal and neonatal care will continue to improve the outcomes of these women and their children. PMID:8583489

  10. Effect of nickel on uterine contraction and ultrastructure in the rat

    1982-04-15

    The in vitro effects of nickel chloride (NiCl/sub 2/) on uterine contractile activity and ultrastructure were studied in uterine strips isolated from 20-day-pregnant Wistar rats. Ni/sup 2 +/ had a dual action on uterine spontaneous contractions. In low concentrations (10/sup -7/M to 10/sup -5/M), NiCl/sub 2/ increased basal tone significantly but had no effect on the amplitude or frequency of development of isometric force. High concentrations of NiCl/sub 2/ (10/sup -4/M to 10/sup -3/M) inhibited spontaneous contractile activity and decreased basal tone, which was antagonized by elevation of the extracellular concentration of Ca/sup 2 +/. Electron microscopic localization of Ni by the dimethyl glyoxime cytochemical technique showed that, after incubation of uterine strips in a physiologic medium that contained 10/sup -6/M NiCl/sub 2/, electron-dense Ni-dimethyl glyoxime particles could be observed in the cytoplasm and in the mitochondria of uterine smooth muscle cells. Exposition of Ni caused mitochondrial structural damage and accumulation of glycogen. The experimental results indicate that, because of its oxytocic action, the increase in the serum level of Ni in the advanced stage of human labor (Rubanyi and associates, 1982) may support separation of the placenta and/or may contribute to the prevention of atonic bleeding in the postpartum period.

    Rupture of the gravid uterus is one of the most grievous obstetric events accounting for considerable maternal morbidity and mortality. An audit over a period of 2 years from October 2010 to September 2012 was performed on pregnant women irrespective of gestational age who had a uterine rupture of a uterus, presumed to be unscarred. There were 141 ruptures among 43,886 deliveries (0.3%). Of those, 18 (12.8% of the ruptures and 0.04% of the deliveries) occurred in presumed unscarred uteri. The aetiologies were: obstruction 50%, uterine anomaly 22.2%, oxytocic administration 16.6 %, instrumental deliveries 5.5% and miscellaneous 11.1 %. Hysterectomy was performed in 55.6% of cases. Fetal mortality was 83.3% and maternal mortality was 16.6%. Training of traditional birth attendants for early referrals, screening for uterine anomalies by ultrasound in early pregnancy and counselling the women, especially multiparas and grand-multiparas are mandatory. Oxytocin should only be used for those if the doctor who prescribed its use stays with the patient continuously and stops oxytocics as soon as there are reasonable contractions. In emergency, the decision to delivery time should be less than 30 min. These are some ways through which a tragic event like uterine rupture and its consequences can be averted. © The Author(s) 2015.

    2012-01-01

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

    2009-06-01

    We present a numerical method to simulate spontaneous shear crack propagation within a heterogeneous, 3-D, viscoelastic medium. Wave motions are computed on a logically rectangular hexahedral mesh, using the generalized finite-difference method of Support Operators (SOM). This approach enables modelling of non-planar surfaces and non-planar fault ruptures. Our implementation, the Support Operator Rupture Dynamics (SORD) code, is highly scalable, enabling large-scale, multiprocessors calculations. The fault surface is modelled by coupled double nodes, where rupture occurs as dictated by the local stress conditions and a frictional failure law. The method successfully performs test problems developed for the Southern California Earthquake Center (SCEC)/U.S. Geological Survey (USGS) dynamic earthquake rupture code validation exercise, showing good agreement with semi-analytical boundary integral method results. We undertake further dynamic rupture tests to quantify numerical errors introduced by shear deformations to the hexahedral mesh. We generate a family of meshes distorted by simple shearing, in the along-strike direction, up to a maximum of 73°. For SCEC/USGS validation problem number 3, grid-induced errors increase with mesh shear angle, with the logarithm of error approximately proportional to angle over the range tested. At 73°, rms misfits are about 10 per cent for peak slip rate, and 0.5 per cent for both rupture time and total slip, indicating that the method (which, up to now, we have applied mainly to near-vertical strike-slip faulting) is also capable of handling geometries appropriate to low-angle surface-rupturing thrust earthquakes. Additionally, we demonstrate non-planar rupture effects, by modifying the test geometry to include, respectively, cylindrical curvature and sharp kinks.

    We evaluated the effectiveness of transcatheter arterial coil embolization therapy for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients. Three patients were treated for massive hemothorax caused by arterial lesions associated with neurofibromatosis. Bleeding episodes were secondary to ascending cervical artery aneurysm and dissection of vertebral artery in 1 patient, and intercostal artery aneurysm with or without arteriovenous fistula in 2 patients. Patients were treated by transarterial coil embolization combined with chest drainage. In 1 patient, the ruptured ascending cervical artery aneurysm was well embolized but, shortly after the embolization, fatal hemorrhage induced by dissection of the vertebral artery occurred and the patient died. In the other 2 patients, the ruptured intercostal artery aneurysm was well embolized and they were successfully treated and discharged. Transcatheter arterial coil embolization therapy is an effective method for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients.

  15. Infertility and uterine fibroids.

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

    The high rates of morbidity and mortality after subarachnoid hemorrhage due to spontaneous rupture of an intracranial aneurysm are mainly the result of neurologic complications. Sixty years after cerebral vasospasm was first described, this problem remains unsolved in spite of its highly adverse effect on prognosis after aneurysmatic rupture. Treatment is somewhat empirical, given that uncertainties remain in our understanding of the pathophysiology of this vascular complication, which involves structural and biochemical changes in the endothelium and smooth muscle of vessels. Vasospasm that is refractory to treatment leads to cerebral infarction. Prophylaxis, early diagnosis, and adequate treatment of neurologic complications are key elements in the management of vasospasm if neurologic damage, lengthy hospital stays, and increased use of health care resources are to be avoided. New approaches to early treatment of cerebral lesions and cortical ischemia in cases of subarachnoid hemorrhage due to aneurysm rupture should lead to more effective, specific management.

    Intra-uterine adhesions are a major cause of secondary infertility. The prevalence of adhesions is probably underestimated due to the heterogeneity of the symptoms. An exhaustive literature search using search engines MEDLINE, Pubmed, Cochrane library and Web of Science was performed to make a focus on the origins, consequences and methods of prevention of intra-uterine adhesions. Intra-uterine adhesions are likely to occur after any endo-uterine surgery via dysregulated activation of coagulation chain linked to the inflammatory process. Early and late obstetric complications are also recognized as caused by adhesions. The diagnosis is currently performed by hysteroscopy but it remains an invasive procedure even if it can be done with an ambulatory management. Several research approaches inspired by intra-abdominal surgery for the prevention of pelvic adhesions have been developed. However, no current method of prevention has proven its effectiveness in terms of improving spontaneous fertility. The improvement in surgical practices, the design of new intra-uterine medical devices and new research especially in the field of endometrial stem cells can maybe reduce the rate of adhesions end their complications after intra-uterine surgery.

    Dysmenorrhea is a common condition among women in childbearing age. An increased uterine contractions, resulting among others from increased vasopressin and oxitocin secretion, is considered as a main cause of the primary dysmenorrhea. The endogenous opioids play the important role in the control of oxytocin and vasopressin release from the pituitary gland. Naloxone is a selective opioid receptor antagonis. So far, there is not much data on naloxone effect on uterine contractions. The aim of study was to determine the influence of naloxone on uterine contractions in patients with primary dysmenorrhea. There were 10 female patients with primary dysmenorrhea included into the study. The uterine contractions had been recorded for 30 minutes before and 2 hours after injection of naloxone at the first day of menstruation. The intrauterine pressure recordings revealed a severe spontaneous uterine contractions, with high frequency and amplitude, at the time of dysmenorrhea. An intravenous administration of naloxone decreased uterine contractile activity and pain intensity. Naloxone acting on central nervous system decreases the uterus contractions in the patients suffering from dysmenorrhea. Unexplained mechanisms and multiple factors involved in the pathogenesis of primary dysmenorrhea indicates a need for the further studies on this subject.

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

    Spontaneous, idiopathic urinary bladder rupture is a very rare disease entity, which may face the problem of proper preoperative diagnosis. In many cases the medical history, physical examination, and additional tests raise false suspicion of gastrointestinal perforation. The study presented a case of a female patient with spontaneous urinary bladder perforation, paying particular attention to the diagnostic difficulties associated with the above-mentioned pathology. The aim of the study was to analyse the presence of symptoms and imaging and laboratory results observed in case of spontaneous urinary bladder rupture, as well as differentiate the above-mentioned pathology with gastrointestinal perforation. Whenever diagnosing a patient with acute peritonitis symptoms, in whom the predominating symptoms include sudden abdominal pain, peritoneal cavity fluid presence, hematuria, oliguria, and coexisting increased urea, creatinine, and potassium levels, one should consider the possibility of urinary bladder rupture.

    Background Uterine fibroids are the most common non-malignant growths in women of childbearing age. They are associated with heavy menstrual bleeding and subfertility. Herbal preparations are commonly used as alternatives to surgical procedures. Objectives To assess the benefits and risks of herbal preparations for uterine fibroids. Search strategy Authors searched following electronic databases: the Trials Registers of the Cochrane Menstrual Disorders and Subfertility Group and the Cochrane Complementary Medicine Field, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2008, Issue 3), MEDLINE, EMBASE, the Chinese Biomedical Database, the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS), AMED, and LILACS. The searches ended on 31st December 2008. Selection criteria Randomised controlled trials comparing herbal preparations with no intervention, placebo, medical treatment or surgical procedures in women with uterine fibroids. We also included trials of herbal preparations with or without conventional therapy. Data collection and analysis Two review authors collected data independently. We assessed trial risk of bias according to our methodological criteria. We presented dichotomous data as risk ratios (RR) and continuous outcomes as mean difference (MD), both with 95% confidence intervals (CI). Main results We included two randomised trials (involved 150 women) with clear description of randomisation methods. The methodological risk of bias of the trials varied. There were variations in the tested herbal preparations, and the treatment duration was six months. The outcomes available were not the primary outcomes selected for this review, such as symptom relief or the need for surgical treatment; trials mainly reported outcomes in terms of shrinkage of the fibroids. Compared with mifepristone, Huoxue Sanjie decoction showed no significant difference in the disappearance of uterine fibroids, number of

    Spontaneous rupture of the renal collecting system is a rare but serious complication of pregnancy. We report a case of nontraumatic left renal calyceal rupture in a pregnancy which ultimately progressed to preterm delivery. A 29-year-old primigravida with a remote history of urolithiasis presented with left flank pain, suprapubic pain, and signs of preterm labor at 33 weeks of gestation. The patient was believed to have urolithiasis, although initial renal ultrasound failed to demonstrate definitive calculi. After a temporary improvement in flank pain with medication, the patient experienced acute worsening of her left flank pain. Urology was consulted and further imaging was obtained. Magnetic resonance imaging (MRI) was consistent with bilateral hydronephrosis and rupture of the left renal calyx. Given the patient's worsening pain in the setting of left calyceal rupture, the urology team planned for placement of a left ureteral stent. However, before the patient could receive her stent, she progressed to active labor and delivered a viable female infant vaginally. Following delivery, the patient's flank pain resolved rapidly and spontaneously, so no surgical intervention was performed. A summary of the literature and the details of this specific clinical situation are provided. PMID:26483981

    To determine the incidence of bilateral distal biceps tendon ruptures. A retrospective review of 321 patients who underwent operative repair of a distal biceps tendon rupture between 1988 and 2010 identified 26 patients with bilateral ruptures. We recorded patient age, mechanism of injury, time between symptom onset before the first surgery and subsequent contralateral symptoms, and time between surgeries. Twenty-two bilateral ruptures were confirmed intra-operatively, 3 by MRI, and 1 was lost to follow up. A total of 23 bilateral ruptures (92%) occurred in men. The average age at the initial rupture was 44 years (range, 29-74 y). The average age at subsequent rupture was 48 years (range, 36-79 y). Excluding the 2 women (age 72 and 79 y), the average age at the initial rupture was 42 years and the average age at subsequent rupture was 46 years. The average interval between ruptures was 4.1 years (range, 0.8-13.9 y). The initial rupture occurred in the dominant extremity in 12 cases (50%) and in the nondominant extremity in 10 cases (42%); in 3 patients (8%) the dominance was not documented or ambidextrous. Thirty-three percent were heavy laborers, 3 patients had a smoking history, and 1 patient reported a history of steroid use. Twenty-two patients (88%) had the second side repaired, where we noted that 12 (55%) of the second tendon ruptures were partial tears. The 8% cumulative incidence of bilateral biceps tendon ruptures in a consecutive series of biceps tendon repairs may be higher because not all patients were contacted, which introduced a sampling bias. This 8% rate is markedly higher than the reported rate of 1.2 per 100,000 for an isolated distal biceps tendon rupture. This implies that patients with a distal biceps tendon rupture are at risk for a rupture on the contralateral side. Prognostic III. Copyright © 2012 American Society for Surgery of the Hand.

    2004-11-01

    Bursting of soap film is a fast and fascinating process. It turns out that certain polymer films rupture in a somewhat similar fashion, but much slower. The slowness of the process allows one to study the rupture of polymer films with details. The rupture process in Hele-Shaw-like fashion shows remarkable properties, and is a very simple system. It turns out that propagation speed of the rupture is a function of the film thickness, and rheologic properties of the polymer. Experimental results will be compared with theory, together with demonstration of the experiment.

    PubMed

    2015-10-01

    Multiple previous reports have provided compelling support for the premise that spontaneous parturition is mediated by activation of inflammation-related signaling pathways leading to increased secretion of cytokines and chemokines, the influx of neutrophils and macrophages into the pregnant uterus, increased production of uterine activation proteins (eg, connexin-43, cyclo-oxygenase-2, oxytocin receptors, etc), activation of matrix metalloproteinases, and the release of uterotonins leading to cervical ripening, membrane rupture, and myometrial contractions. The missing link has been the fetal/placental signal that triggers these proinflammatory events in the absence of microbial invasion and intrauterine infection. This article reviews the biomedical literature regarding the increase in cell-free fetal DNA (cffDNA), which is released during apoptosis in the placenta and fetal membranes at term, the ability of apoptosis modified vertebrate DNA to stimulate toll-like receptor-9 (TLR9) leading to increased release of cytokines and chemokines, and the potential "fail-safe" role for the anti-inflammatory cytokine IL-10. This article also reviews the literature supporting the key role that telomere loss plays in regard to increasing the ability of vertebrate (including placental) DNA to stimulate TLR9, and in regard to signaling the onset of apoptosis in the placenta and fetal membranes, thereby providing a biologic clock that determines the length of gestation and the timing for the onset of parturition. In summary, this literature review provides a strong rationale for future research to test the hypothesis that telomere loss and increased cffDNA levels trigger the proinflammatory events leading to the spontaneous onset of parturition in mammals: the "cffDNA/telomere hypothesis." © The Author(s) 2015.

    In 176 diamniotic twin pregnancies at 10-20 weeks of gestation, amniotic fluid for cytogenetic studies was successfully obtained from both sacs by the use of a single uterine entry. There were no cases of discordancy between sex at amniocentesis and birth. There were six pregnancies with fetal unbalanced chromosomal defects; in one pregnancy both fetuses were abnormal and in five pregnancies only one fetus was abnormal. The total fetal loss rate was 5.7% (20 of 352 fetuses), including six (1.7%) terminations or selective fetocides and 14 (4.0%) spontaneous deaths. In the 176 pregnancies there were five (2.8%) with no survivors, including one termination and four (2.3%) spontaneous miscarriages or intrauterine deaths. There are only two (1.1%) pregnancies in which amniocentesis could have contributed directly to the losses and therefore the procedure-related rate of fetal loss may be similar to that in singleton pregnancies. The median gestation at delivery was 37 (range 16-40) weeks and delivery before 32 weeks occurred in 9% of the pregnancies. The birth weight distribution was similar to that reported in singleton pregnancies. This study demonstrates that in twin pregnancies amniotic fluid for cytogenetic studies can be obtained successfully from both sacs by use of a single uterine entry. The risk of fetal loss from this procedure appears to be similar to that in singleton pregnancies.

    In the young population, spontaneous rupture of Achilles tendon is very rare. The big hematoma is also rare finding of the Achilles tendon partial rupture. It is usually seen with complete rupture. We presented imaging findings of 4 years follow up of the spontaneous partial rupture of Achilles tendon presenting with giant expanding hematoma and mimicking complete rupture radiologically. We discussed the alterations of tendon signal intensity and result of conservative therapy after partial rupture with big hematoma in the long term. A 29 year-old man, applied with pain and swelling in the retrocalcaneal region of left ankle. He did not have chronic metabolic disease. He was not active in physical activities. X-ray radiograms were normal. At magnetic resonance images (MRI), there was an intratendinous big hematoma, subcutanous fat planes were edematous around tendon. The diagnosis was partial rupture and giant hematoma. Hematoma was drained. The conservative treatment was applied and his complaints disappeared. After treatment, approximately 4 years later, control MRI showed thickened and hypointense tendon in all images. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

  17. Investigation of Women with Postmenopausal Uterine Bleeding: Clinical Practice Recommendations

    PubMed Central

    Munro, Malcolm G

    2014-01-01

    Postmenopausal uterine bleeding is defined as uterine bleeding after permanent cessation of menstruation resulting from loss of ovarian follicular activity. Bleeding can be spontaneous or related to ovarian hormone replacement therapy or to use of selective estrogen receptor modulators (eg, tamoxifen adjuvant therapy for breast carcinoma). Because anovulatory “cycles” with episodes of multimonth amenorrhea frequently precede menopause, no consensus exists regarding the appropriate interval of amenorrhea before an episode of bleeding that allows for the definition of postmenopausal bleeding. The clinician faces the possibility that an underlying malignancy exists, knowing that most often the bleeding comes from a benign source. Formerly, the gold-standard clinical investigation of postmenopausal uterine bleeding was institution-based dilation and curettage, but there now exist office-based methods for the evaluation of women with this complaint. Strategies designed to implement these diagnostic methods must be applied in a balanced way considering the resource utilization issues of overinvestigation and the risk of missing a malignancy with underinvestigation. Consequently, guidelines and recommendations were developed to consider these issues and the diverse spectrum of practitioners who evaluate women with postmenopausal bleeding. The guideline development group determined that, for initial management of spontaneous postmenopausal bleeding, primary assessment may be with either endometrial sampling or transvaginal ultrasonography, allowing patients with an endometrial echo complex thickness of 4 mm or less to be managed expectantly. Guidelines are also provided for patients receiving selective estrogen receptor modulators or hormone replacement therapy, and for an endometrial echo complex with findings consistent with fluid in the endometrial cavity.

    The aim of this guideline is to provide clinicians with an understanding of the pathophysiology, prevalence, and clinical significance of myomata and the best evidence available on treatment modalities. The areas of clinical practice considered in formulating this guideline were assessment, medical treatments, conservative treatments of myolysis, selective uterine artery occlusion, and surgical alternatives including myomectomy and hysterectomy. The risk-to-benefit ratio must be examined individually by the woman and her health care provider. Implementation of this guideline should optimize the decision-making process of women and their health care providers in proceeding with further investigation or therapy for uterine leiomyomas, having considered the disease process and available treatment options, and reviewed the risks and anticipated benefits. Published literature was retrieved through searches of PubMed, CINAHL, and Cochrane Systematic Reviews in February 2013, using appropriate controlled vocabulary (uterine fibroids, myoma, leiomyoma, myomectomy, myolysis, heavy menstrual bleeding, and menorrhagia) and key words (myoma, leiomyoma, fibroid, myomectomy, uterine artery embolization, hysterectomy, heavy menstrual bleeding, menorrhagia). The reference lists of articles identified were also searched for other relevant publications. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits but results were limited to English or French language materials. Searches were updated on a regular basis and incorporated in the guideline to January 2014. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, and national and international medical specialty societies. The majority of fibroids are asymptomatic and require no intervention or further

    Alpha-tocopherol has been implicated in reproduction processes, and deficiency of phylloquinone has been associated with serious complications in pregnancy. This study was therefore aimed at investigating the effects of phylloquinone and alpha-tocopherol on uterine contractility and female reproductive function using mouse models. Both in vivo and ex vivo animal models were employed and designed to assess changes on uterine contractility and reproductive functions in the non-pregnant uterus. The effect of alpha-tocopherol and phylloquinone on spontaneous uterine contractions, oxytocin-induced uterine contractions (11.82nM) and high KCl-induced tonic uterine contractions (80mM) were assessed. The effect of subcutaneous administration of alpha-tocopherol (10mg/kg) on reproductive hormone levels and reproductive tissues were also determined. Alpha-tocopherol increased the force of contractions while phylloquinone decreased the force of uterine contractions. Plasma levels of luteinizing hormone (P<0.01), estrogen (P<0.01) and progesterone (P<0.001) were elevated in the presence of alpha-tocopherol after 6 days subcutaneous administration. Alpha-tocopherol and phylloquinone have been shown to directly modulate uterine contractility and reproductive function and may contribute to the management and treatment of reproductive disorders.

  20. Short-lived Supershear Rupture

    Fukuyama and Olsen (2002) computed the supershear rupture initiation, propagation and termination process due to a passage of high stress drop area (called asperity) using a boundary integral equation method. They found that supershear rupture continued to propagate after the passage through high stress drop area but it died after a certain propagation distance, which depends on the elastic energy released at the high stress drop area. Here, we could reproduce a similar phenomenon in the laboratory. We conducted large-scale biaxial friction experiments using a pair of meter-scaled metagabbro rock specimens (VP=6.9km/s, VS=3.6km/s) at the National Research institute for Earth Science and Disaster Prevention (NIED). We observed several stick slip rupture events that initiated close to an asperity and immediately became supershear ruptures. But after propagating certain distance they died out and co-existing subshear ruptures became prominent. If we look into details, during the supershear rupture, we could see a sequence of rupture acceleration, its short rest and re-acceleration. This feature reminds us of a sequential breakage of small high stress patches as predicted by Fukuyama and Madariaga (2000). These observations might be interpreted under a concept of energy balance where the energy transmission from strain energy released by the asperity to fracture energy consumed at the crack tip was not instantaneously balanced in space. This could be related to the fact that earthquake rupture velocity is rather smooth reported from the finite fault analysis of large earthquakes with seismic waveforms. References Fukuyama, E. and R.

    Pneumomediastinum is usually first identified radiographically in the emergency department. Distinguishing benign from more ominous causes, such as esophageal rupture, is imperative, particularly in the setting of associated esophageal disease. We describe a case, with correlative imaging, of spontaneous pneumomediastinum as the initial presentation of achalasia. A general discussion of spontaneous pneumomediastinum is also provided, including the pathophysiology, precipitating and predisposing factors, clinical manifestations, role of radiology in the diagnosis as well as the radiographic signs.

    Studying the seismicity in a subduction zone and its effects on tsunamis requires diverse modelling methods that span spatial and temporal scales. Hundreds of years are necessary to build the stresses and strengths on a fault, while consequent earthquake rupture propagation is determined by both these initial fault conditions and the feedback of seismic waves over periods of seconds up to minutes. This dynamic rupture displaces the sea floor, thereby causing tsunamis. The aim of the ASCETE (Advanced Simulations of Coupled Earthquake and Tsunami Events) project is to study all these aspects and their interactions. Here, we present preliminary results of the first aspects in this modelling chain: the coupling of a seismo-thermo-mechanical (STM) code to the dynamic rupture model SeisSol. STM models of earthquake cycles have the advantage of solving multiple earthquake events in a self-consistent manner concerning stress, strength and geometry. However, the drawback of these models is that they often lack in spatial or temporal resolution and do not include wave propagation. In contrast, dynamic rupture models solve for frictional failure coupled to seismic wave propagation. We use the software package SeisSol (www.seissol.org) based on an ADER-DG discretization allowing high-order accuracy in space and time as well as flexible tetrahedral meshing. However, such simulations require assumptions on the initial fault stresses and strengths and its geometry, which are hard to constrain due to the lack of near-field observations and the complexity of coseismic conditions. By adapting the geometry as well as the stress and strength properties of the self-consistently developing non-finite fault zones from the geodynamic models as initial conditions for the dynamic rupture models, the advantages of both methods are exploited and modelling results may be compared. Our results show that a dynamic rupture can be triggered spontaneously and that the propagating rupture is

    Objective To determine the presence of calcium activated chloride channels anoctamin 1 and 2 in human and murine uterine smooth muscle and evaluate the physiologic role for these ion channels in murine myometrial contractility. Study Design We performed reverse transcription polymerase chain reaction to determine if anoctamin 1 and 2 are expressed in human and murine uterine tissue to validate the study of this protein in mouse models. Immunohistochemical staining of anoctamin 1 and 2 was then performed to determine protein expression in murine myometrial tissue. The function of anoctamin 1 and 2 in murine uterine tissue was evaluated using electrophysiological studies, organ bath, and calcium flux experiments. Results Anoctamin 1 and 2 are expressed in human and murine USM cells. Functional studies show that selective antagonism of these channels promotes relaxation of spontaneous murine uterine smooth muscle contractions. Blockade of anoctamin 1 and 2 inhibits both agonist-induced and spontaneous transient inward currents and abolishes G-protein coupled receptor (oxytocin) mediated elevations in intracellular calcium. Conclusion The calcium activated chloride channels ANO 1 and 2 are present in human and murine myometrial tissue and may provide novel potential therapeutic targets to achieve effective tocolysis.

    Objective To describe the blood flow velocities and impedance indices changes in the uterine arteries of leiomyomatous uteri using Doppler sonography. Methods This was a prospective, case-control study conducted on 140 premenopausal women with sonographic diagnosis of uterine leiomyoma and 140 premenopausal controls without leiomyomas. Pelvic sonography was performed to diagnose and characterize the leiomyomas. The hemodynamics of the ascending branches of both main uterine arteries was assessed by Doppler interrogation. Statistical analysis was performed mainly using non-parametric tests. Results The median uterine volume of the subjects was 556 cm(3), while that of the controls was 90.5 cm(3) (p < 0.001). The mean peak systolic velocity (PSV), end-diastolic velocity (EDV), time-averaged maximum velocity (TAMX), time-averaged mean velocity (Tmean), acceleration time (AT), acceleration index (AI), diastolic/systolic ratio (DSR), diastolic average ratio (DAR), and inverse pulsatility index (PI) were significantly higher in the subjects (94.2 cm/s, 29.7 cm/s, 49.1 cm/s, 25.5 cm/s, 118 ms, 0.8, 0.3, 0.6, and 0.8 respectively) compared with the controls (54.2 cm/s, 7.7 cm/s, 20.0 cm/s, 10.0 cm/s, 92.0 ms, 0.6, 0.1, 0.4, and 0.4 respectively); p < 0.001 for all values. Conversely, the mean PI, resistivity index (RI), systolic/diastolic ratio (SDR) and impedance index (ImI) of the subjects (1.52, 0.70, 3.81, and 3.81 respectively) were significantly lower than those of the controls (2.38, 0.86, 7.23, and 7.24 respectively); p < 0.001 for all values. Conclusion There is a significantly increased perfusion of leiomyomatous uteri that is most likely due to uterine enlargement. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.

    During the past few decades, there has been a significant increase in the number of cesarean deliveries, and thus an increase in the number of complications. A common complication of multiple cesarean deliveries is symptomatic uterine scar dehiscence, for which there are no treatment guidelines available. We report a case of uterine scar dehiscence-the repair of it by robotic surgery-and review the literature on this defect. The patient was a 39-year-old woman, gravida 4 para 2022, complaining of persistent vaginal spotting for the prior 5 months with a history of a cesarean delivery 3 months before the onset of the symptoms. We report a case of a successful robotic repair of a symptomatic cesarean scar defect. We propose further studies that include more patients so this technique may become the standard for cesarean scar defect.

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

    To determine the incidence and predictors of tendon ruptures requiring hospitalization of representative patients with type 2 diabetes. A total of 1296 patients from the longitudinal observational Fremantle Diabetes Study, Phase I, and 5159 de-identified age- and sex-matched control subjects without diabetes from the same urban area were studied. The patients' mean (sd) age was 64.0 (11.3) years and 48.6% of them were male. Their median (interquartile range) diabetes duration was 4.0 (1.0-9.0) years. The main outcome assessed was any tendon rupture requiring hospitalization in the Fremantle Diabetes Study subjects and the matched control subjects. Independent predictors of spontaneous ruptures in the patients from the Fremantle Diabetes Study were assessed using Cox proportional hazards modelling. The incidence rate ratio for any tendon rupture requiring hospitalization in patients vs control subjects was 1.44 (95% CI 1.10-1.87; P = 0.005). Independent predictors of spontaneous ruptures in patients were BMI [hazard ratio 1.05 (95% CI 1.002-1.10] for 1 kg/m2 increase; P = 0.010] and alcohol consumption [hazard ratio 1.52 (95% CI 1.11-2.09) for √1 standard drink/day increase; P = 0.010]. Adjustment of the incidence rate ratio for overall rupture requiring hospitalization for these variables using the BMI and alcohol consumption data from the contemporary Australian general population suggested it could be as high as 1.84. There is a greater risk of tendon rupture requiring hospitalization in people with type 2 diabetes. Alcohol consumption and adiposity are potentially modifiable risk factors of spontaneous ruptures in patients with diabetes. © 2013 The Authors. Diabetic Medicine © 2013 Diabetes UK.

    Iloprost, a combined EP(1) stimulatory and IP inhibitory receptor agonist, was tested in vitro on myometrium from the lower uterine segment of pregnant rhesus monkeys to compare its effects in spontaneous labor and in labor induced by the administration of androstenedione to the mother. Pregnant rhesus monkeys carrying fetuses of known gestational age were instrumented under halothane general anesthesia with femoral artery and vein catheters and uterine electromyogram leads. Experimental animals were infused with androstenedione from 139 days' gestation. Control animals were infused with intralipid vehicle from 139 days' gestation. Lower uterine segment myometrium was removed from control animals either before labor began (n = 6) or in spontaneous labor (n = 4) and from animals undergoing premature labor induced by androstenedione (n = 4). Myometrial contractility in response to iloprost was evaluated using a superfusion system in vitro. Iloprost was inhibitory on myometrium obtained from the lower uterine segment from androstenedione-treated animals as well as vehicle-infused animals in spontaneous term labor. In contrast, iloprost had no effect on myometrial strips from control animals not in labor. These findings indicate up-regulation of IP receptors which inhibit myometrial contractility and/or down-regulation of EP(1) receptors which stimulate myometrial contractility in the lower uterine segment during labor. A relative increase in inhibitory responses in the lower uterine segment during labor may enable this region to dilate to allow passage of the fetus.

    Feline endometrial adenocarcinomas are uncommon malignant neoplasms that have been poorly characterized to date. In this study, we describe a uterine adenocarcinoma in a Persian cat with feline leukemia virus infection. At the time of presentation, the cat, a female Persian chinchilla, was 2 years old. The cat underwent surgical ovariohystectomy. A cross-section of the uterine wall revealed a thickened uterine horn. The cat tested positive for feline leukemia virus as detected by polymerase chain reaction. Histopathological examination revealed uterine adenocarcinoma that had metastasized to the omentum, resulting in thickening and the formation of inflammatory lesions. Based on the histopathological findings, this case was diagnosed as a uterine adenocarcinoma with abdominal metastasis. To the best of our knowledge, this is the first report of a uterine adenocarcinoma with feline leukemia virus infection.

    A uterine arteriovenous malformation (AVM) is an uncommon cause of uterine bleeding. Location of this lesion in the uterine cervix is exceptional. We report a case of a 34-year-old woman who presented with chronic menorrhagias and hypochromic anemia. A sonographic study revealed a 10-cm, fundal, intramural, uterine well-circumscribed mass that distorted the endometrial cavity. The patient underwent hysterectomy for a large uterine leiomyoma. The pathological study revealed an incidental AVM of the posterior half of the cervix measuring 5.5 cm in major diameter. We suggest that in our case cervical AVM might have occurred due to a large corporal leiomyoma distorting the uterine circulation. Differential diagnosis includes capillary hemangioma, venous malformation, or arteriovenous fistula. Copyright © 2015 Elsevier GmbH. All rights reserved.

    Evaluation of synchronization between myoelectric signals can give new insights into the functioning of the complex system of porcine myometrium. We propose a model of uterine contractions according to the hypothesis of action potentials similarity which is possible to detect during propagation in the uterine wall. We introduce similarity measures based on the concept of synchronization as used in matching linear signals such as electromyographic (EMG) time series data. The aim was to present linear measures to assess synchronization between contractions in different topographic regions of the uterus. We use the cross-correlation function (ƒx,y[l], ƒy,z[l]) and the cross-coherence function (Cxy[ƒ], Cyz[ƒ]) to assess synchronization between three data series of a diestral uterine EMG bundles in porcine reproductive tract. Spontaneous uterine activity was recorded using telemetry method directly by three-channel transmitter and three silver bipolar needle electrodes sutured on different topographic regions of the reproductive tract in the sow. The results show the usefulness of the cross-coherence function in that synchronization between uterine horn and corpus uteri for multiple action potentials (bundles) could be observed. The EMG bundles synchronization may be used to investigate the direction and velocity of EMG signals propagation in porcine reproductive tract. Copyright © 2016 Elsevier Inc. All rights reserved.

    Uterine factors represent only 2 to 3 % of infertility, but intra-uterine lesions are much more common in infertile women (40-50 %). These lesions can interfere with spontaneous fertility and can compromise pregnancy rates in assisted reproduction. Exploration of the uterine cavity is actually one of the basic explorations in infertility workup. Classically, hysterosalpingography and transvaginal sonography are most communally used for this purpose. Hysteroscopy, with the development and miniaturization of equipment, is currently simple, outpatient cost-effective exploration and it is considered the gold standard for diagnosis of intrauterine lesions. However, the benefit of the systematic use of hysteroscopy in the initial assessment of infertility remains unclear and the exploration of the uterine cavity in the initial assessment of infertility should be based on hysterosalpingography or hysterosonography. Systematic hysteroscopy before IVF is widely accepted practice that is supposed to improve pregnancy rates but still lacks scientific evidence. After repeated implantation failure in IVF cycles, uterine cavity should be reevaluated by hysteroscopy and this practice has been demonstrated to improve pregnancy rates.

  13. Fault branching and rupture directivity

    NASA Astrophysics Data System (ADS)

    Fliss, Sonia; Bhat, Harsha S.; Dmowska, Renata; Rice, James R.

    2005-06-01

    Could the directivity of a complex earthquake be inferred from the ruptured fault branches it created? Typically, branches develop in forward orientation, making acute angles relative to the propagation direction. Direct backward branching of the same style as the main rupture (e.g., both right lateral) is disallowed by the stress field at the rupture front. Here we propose another mechanism of backward branching. In that mechanism, rupture stops along one fault strand, radiates stress to a neighboring strand, nucleates there, and develops bilaterally, generating a backward branch. Such makes diagnosing directivity of a past earthquake difficult without detailed knowledge of the branching process. As a field example, in the Landers 1992 earthquake, rupture stopped at the northern end of the Kickapoo fault, jumped onto the Homestead Valley fault, and developed bilaterally there, NNW to continue the main rupture but also SSE for 4 km forming a backward branch. We develop theoretical principles underlying such rupture transitions, partly from elastostatic stress analysis, and then simulate the Landers example numerically using a two-dimensional elastodynamic boundary integral equation formulation incorporating slip-weakening rupture. This reproduces the proposed backward branching mechanism based on realistic if simplified fault geometries, prestress orientation corresponding to the region, standard lab friction values for peak strength, and fracture energies characteristic of the Landers event. We also show that the seismic S ratio controls the jumpable distance and that curving of a fault toward its compressional side, like locally along the southeastern Homestead Valley fault, induces near-tip increase of compressive normal stress that slows rupture propagation.

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

    Abnormal uterine bleeding is one of the commonest presenting complaints encountered in a gynecologist's office or primary-care setting. The wider availability of diagnostic tools has allowed prompt diagnosis and treatment of an increasing number of menstrual disorders in an office setting. This White Paper reviews the advantages and disadvantages of transvaginal ultrasound, blind endometrial sampling and diagnostic hysteroscopy. Once a proper diagnosis has been established, appropriate therapy may be embarked upon. Fortunately, only a minority of such patients will have premalignant or malignant disease. When bleeding is sufficient to cause severe anemia or even hypovolemia, prompt intervention is called for. In most of the cases, however, the abnormal uterine bleeding will be disquieting to the patient and significantly affect her 'quality of life'. Sometimes, reassurance and expectant management will be sufficient in such patients. Overall, however, in cases of benign disease, some intervention will be required. The use of oral contraceptive pills especially those with a short hormone-free interval, the insertion of the levonorgestrel intrauterine system, the incorporation of newer medical therapies including antifibrinolytic drugs and selective progesterone receptor modulators and minimally invasive treatments have made outpatient therapy increasingly effective. For others, operative hysteroscopy and endometrial ablation are proven therapeutic tools to provide both long- and short-term relief of abnormal uterine bleeding, thus avoiding, or deferring, hysterectomy.

  16. Dynamic Rupture Segmentation Along The Nankai Trough, Southwest Japan

    NASA Astrophysics Data System (ADS)

    2010-12-01

    In southwest Japan, large devastating earthquakes (Mw>8) occurred along the Nankai subduction zone every 100-200 years (e.g. Ando, 1975, Tectonophys.; Ishibashi, 2004, Ann. Geophys.). Historical records revealed the segmented nature of the 600 km long seismogenic zone, producing Nankai and Tonankai earthquakes to occur separately or jointly at each cycle. The intersegment zone which separates Nankai and Tonankai source areas, near the Kii Peninsula, should have some special physical properties. In this study, we investigate the dynamic linkage of the coseismic slips on the Nankai and Tonankai segments, by modeling the spontaneous rupture propagation on the subduction interface. To conduct a reliable modeling, the parameters’ lateral variations along the place interface are introduced by combining several geophysical observation data sets. First, we use a large-scale 3D geometry for the plate interface, inferred from seismicity; we also integrate the slip deficit distribution (Hashimoto et al., 2009, SSJ meeting) obtained by inversion of GPS data, to constrain the distribution of stress drop on the interface. This distribution is not uniform, and explains the 1st order asperities of the subduction zone: Hyuga, Nankai, Tonankai and Tokai areas appear clearly as loaded regions. In addition, a constitutive friction law is required to link fault slip and stress release. We compiled regional geophysical information relevant to the segmentation, to infer the distribution of the frictional parameters at seismogenic depths. We focused on areas where the rupture is known to have stopped. The barriers seem to be related to upper plate structure (Wells et al. 2003, JGR, Rosenau and Oncken 2009, JGR). Uplifted areas show common characteristics: end of seismogenic segments, underplating in the wedge, and higher density of the upper old wedge (granitic intrusions). Following above review, we introduced 3 barrier regions delimiting 2 asperity regions (Nankai and Tonankai

    Extensor tendon ruptures in the rheumatoid wrist are usually restored by extensor tendon reconstruction surgery. However, the factors significantly correlated with the outcomes of extensor tendon reconstruction have not been defined. We examined factors showing a statistically significant correlation with postoperative active motion after tendon reconstruction. Spontaneous extensor tendon ruptures of 66 wrists in patients (mean age, 52.6 yrs) with rheumatoid arthritis (RA) were evaluated. All patients underwent tendon reconstruction surgery with wrist arthroplasty or arthrodesis. Active ranges of motion of the affected fingers were evaluated at 12 weeks postsurgery. Statistical significance was determined using multiple and single regression analyses. Forty-six (69.6%) wrists had "good" results, while 13 (19.7%) and 7 (10.6%) wrists had "fair" and "poor" results, respectively. In multiple regression analysis, an increased number of ruptured tendons and the age at operation were independent variables significantly correlated with the postoperative active motion of reconstructed tendons (p = 0.009). Single regression analysis also showed a significant association between the number of ruptured tendons and surgical delay (p = 0.02). The number of ruptured extensor tendons was significantly correlated with the results of tendon reconstruction, and the number of ruptured tendons was significantly correlated with preoperative surgical delay. Our results indicate that, in patients presenting with possible finger extensor tendon rupture, rheumatologists should consult with hand surgeons promptly to preserve hand function.

    Rheumatoid flexor tenosynovitis at the wrist can cause locking, limitation of motion, nerve compression, and rupture of tendons. To prevent and treat these conditions, a flexor tenosynovectomy, combined with nerve decompression and tendon reconstruction as indicated, is necessary. If tendons are ruptured, the flexor pollicis longus and profundus to the index finger are most commonly affected. On the fingers flexor tenosynovitis can also cause locking, decrease in range of motion and rupture tendons. Flexor tenosynovitis of the fingers should be treated with decompression of the tendons health with preservation of the pulley system.

  20. Uterine structural anomalies and arthrogryposis-death of an urban legend.

    2013-01-01

    In a review of 2,300 cases of arthrogryposis collected over the last 35 years, 33 cases of maternal uterine structural anomalies were identified (1.3%). These cases of arthrogryposis represent a very heterogeneous group of types of arthrogryposis. Over half of individuals affected with arthrogryposis demonstrated asymmetry and some responded to removal of constraint, 29 of the 33 cases of arthrogryposis whose mother had a uterine structural anomaly could be identified as having a specific recognizable type of arthrogryposis. Only two cases (0.08%) had primarily proximal contractures that returned to almost normal function within 1 year. Craniofacial asymmetry was the most striking finding in these two cases. A quarter of cases had ruptured membranes between 32 and 36 weeks and either oligohydramnios or prematurity. The pregnancy histories of the mothers with uterine structural anomalies were typical in having infertility, multiple miscarriages, and stillbirths. The finding of only two cases which are likely to have multiple congenital contractures on the basis of uterine constraint suggests that it is a very rare primary cause of arthrogryposis.
