Rectal prolapse.

INTRODUCTION: Rectal prolapse, or procidentia, is defined as a protrusion of the rectum beyond the anus. It commonly occurs at the extremes of age. Rectal prolapse frequently coexists with other pelvic floor disorders, and patients have symptoms associated with combined rectal and genital prolapse. Few patients, a lack of randomized trials and difficulties in the interpretation of studies of anorectal physiology have made the understanding of this disorder difficult. METHODS OF TREATMENT: Surgical management is aimed at restoring physiology by correcting the prolapse and improving continence and constipation, whereas in patients with concurrent genital and rectal prolapse, an interdisciplinary surgical approach is required. Operation should be reserved for those patients in whom medical treatment has failed, and it may be expected to relieve symptoms. Numerous surgical procedures have been suggested to treat rectal prolapse. They are generally classified as abdominal or perineal according to the route of access. However, the controversy as to which operation is appropriate cannot be answered definitively, as the extent of a standardized diagnostic assessment and the types of surgical procedures have not been identified in published series. LITERATURE REVIEW: This review encompasses rectal prolapse, including aetiology, symptoms and treatment. The English-language literature about rectal prolapse was identified using Medline, and additional cited works not detected in the initial search were obtained. Articles reporting on prospective and retrospective comparisons and case reports were included.

[Mitral valve prolapse].

Mitral valve prolapse has previously been found to be associated with severe cardiovascular complications such as embolic insults, infectious endocarditis, and sudden cardiac death. However, at the same time, in particular after adopting M-mode and 2D echo for diagnosis, prevalence of the disease was found to be very high, especially in the young. The dilemma of a disease which is frequent and mostly asymptomatic, but in some cases has catastrophic complications, has been solved by implementation of more restrictive diagnostic criteria based on an appreciation of the spatial morphology of the mitral annulus. These criteria call for diagnosis exclusively based on long axis views and a prolapse of > 2 mm beyond a line connecting the leaflet insertion points. "Classic prolapse" additionally requires diastolic thickness of the mitral leaflets of at least 5 mm. Two recent studies, a population-based study of mitral valve prolapse prevalence, and a case-control study of juvenile stroke patients compared to a group of young patients without a history of stroke, shed further light on this disease. The authors found that prevalence of mitral valve prolapse in an average population is 2-3% (1.3% for classic prolapse), without age or sex preponderance; the rate of cerebrovascular insults, congestive heart failure, and atrial fibrillation of patients with prolapse does not exceed that of the rest of the population; however, mitral insufficiency is more frequent; young patients with a history of cerebrovascular insult do not have higher mitral valve prolapse rates than young patients without previous insult.

Pathophysiology and prevention of loop stomal prolapse in the transverse colon.

We investigated both pathogenesis and prevention of loop transverse stomal prolapse. Seven patients with reducible prolapsed stoma were studied under fluoroscopy after staining the prolapsed stoma and the colon by barium medium while prolapsing or reducing the stoma with or without the stomal wall pressed on to the abdominal wall of fascial plane. All prolapses occurred in the distal limbs of the loop stoma with the distal transverse colons redundant. The prolapse started around the mucocutaneous suture with the stoma inflated and the colon in it depressed and proceeded in accordance with an addition of abdominal pressure, but did not occur by pressing of the stomal wall. Prolapse of transverse loop stoma occurs when redundant colon invades the stoma with an abdominal pressure. Stomal prolapse might be prevented by fixation of the colon to the fascia.

Anal sphincter morphology in patients with full-thickness rectal prolapse.

PURPOSE: The aim of this study was to assess the morphologic change of the anal canal in patients with rectal prolapse. METHODS: The endoanal ultrasound scans of 18 patients with rectal prolapse were compared with those of 23 asymptomatic controls. The thickness and area of the internal anal sphincter and submucosa were measured at three levels. RESULTS: Qualitatively, patients with rectal prolapse showed a characteristic elliptical morphology in the anal canal with anterior/posterior submucosal distortion accounting for most of the change. Quantitatively, internal anal sphincter (IAS) and submucosa (SM) thicknesses and area were greater in all quadrants of the anal canal (especially upper) in patients with rectal prolapse compared with controls. There was statistical evidence (in a regression model) of a relationship between increases in all measured variables and the finding of rectal prolapse. CONCLUSIONS: The cause of sphincter distortion in rectal prolapse is unknown but may be a response to increased mechanical stress placed on the sphincter from the prolapse or an abnormal response by the sphincter complex to the prolapse. Patients found to have this feature on endoanal ultrasound should undergo clinical examination and defecography to look for rectal wall abnormalities.

Significance of QT dispersion on ventricular arrhythmias in mitral valve prolapse.

The present study was designed to detect the arrhythmogenic effect of mitral valve prolapse, and the relationship between QT, QT dispersion and ventricular arrhythmias in subjects with mitral valve prolapse. Sixty-four mitral valve prolapse subjects (24 men and 40 women, mean age 27 +/- 6), and 80 healthy control subjects (32 men and 48 women, mean age 28 +/- 7) were studied. The frequency of ventricular arrhythmias by means of 24-h ambulatory electrocardiographic (ECG) monitoring was investigated. Grade > or = 3 ventricular arrhythmias according to modified Lown and Wolf classification were accepted as complex arrhythmias. The QT intervals were measured from the beginning of depolarization of the QRS complex to the end of the T wave. Using the Bazett formula, QT interval was corrected (QTc) for heart rate. QT dispersion was calculated as the difference between the maximum and minimum QT intervals on any of 12 leads. Premature ventricular complexes seemed to develop in 56 of 64 (87.5%) subjects with mitral valve prolapse. Thirty-eight of the mitral valve prolapse subjects had complex premature ventricular complexes during 24-h ECG and the prevalence of premature ventricular complexes was found to be higher than the control subjects (P < 0.001). We found QT and QTc intervals of 388 +/- 27 and 406 +/- 33 ms in mitral valve prolapse subjects, these values in control subjects were 382 +/- 18 and 402 +/- 11 ms respectively (P > 0.05). QT dispersion and QTc dispersion intervals were 71 +/- 17 and 78 +/- 19 ms in mitral valve prolapse subjects and these values were 43 +/- 16 and 52 +/- 22 ms in control subjects, respectively (P < 0.001). No correlation was found between complex premature ventricular complexes and QT, but there was a correlation between complex premature ventricular complexes and QT dispersion in the mitral valve prolapse subjects. It was concluded that QT dispersion might be a useful marker of cardiovascular morbidity and mortality due to complex ventricular arrhythmias.

Morphologic comparison of patients with mitral valve prolapse who died suddenly with patients who died from severe valvular dysfunction or other conditions.

Clinical and necropsy findings are described in 56 patients with mitral valve prolapse: 15 patients, aged 16 to 69 years (mean 39), died suddenly and mitral valve prolapse was the only cardiac condition found at necropsy (hereafter called isolated mitral valve prolapse); the remaining 41 patients had other conditions that were capable of being fatal. Of the latter 41 patients, 7, aged 17 to 59 years (mean 45), had associated congenital heart disease, and 34 patients, aged 17 to 70 years (mean 52), had no associated congenital cardiac abnormalities. Compared with the 34 patients without associated congenital heart disease and with nonmitral valve prolapse conditions capable in themselves of being fatal, the 15 patients who died suddenly with isolated mitral valve prolapse were younger (mean age 39 +/- 17 versus 52 +/- 15 years; p = 0.01), more often women (67% versus 26%; p = 0.008) and had a lower frequency of mitral regurgitation (7% versus 38%; p = 0.02). The 15 patients dying suddenly with isolated mitral valve prolapse also were less likely to have evidence of ruptured chordae tendineae (29% versus 67%; p = 0.04). The frequency of increased heart weight (67% versus 59%), a dilated mitral valve anulus (80% versus 81%), a dilated tricuspid valve anulus (17% versus 17%), an elongated anterior mitral leaflet (86% versus 54%), an elongated posterior mitral leaflet (79% versus 77%) and fibrous endocardial plaque under the posterior mitral leaflet (73% versus 63%) was similar between the two groups. The severity of the prolapse (mild 20% versus 11%; moderate 27% versus 58%; severe 53% versus 32%) also was similar between the two groups. Thus, persons with mitral valve prolapse dying suddenly without another recognized condition tend to be relatively young women without mitral regurgitation.

Obstetric risk factors for symptomatic prolapse: a population-based approach.

OBJECTIVE: The purpose of this study was to identify obstetric risk factors for symptomatic prolapse. STUDY DESIGN: This was a population-based case-control study of prolapse prevalence. RESULTS: Four hundred fifty-four women with self-reported symptomatic pelvic organ prolapse who were identified among 5489 women who participated in a population survey (cases) and 405 control subjects without symptoms were selected randomly from the same survey. All cases and control subjects received a mailed questionnaire with 72 questions about factors that were suspected to be linked to risk and that included obstetric history. The response rate was 76%. Among parous women, the odds for symptomatic pelvic organ prolapse increased with number of childbirths and were 3.3-fold higher among mothers of 4 than among mothers of 1. Indices of excessive stretching and tearing during labor (vaginal lacerations or episiotomies) were associated with increased risk for symptomatic pelvic organ prolapse. Instrumental delivery with forceps or vacuum did not seem to increase the risk of symptomatic pelvic organ prolapse, nor did length of delivery or maternal age at time for delivery. Abdominal deliveries appeared to be protective; the age- and parity-adjusted odds ratio of symptomatic pelvic organ prolapse after > or =1 abdominal deliveries was 0.5 (95% CI, 0.3-0.9), relative to women who had had only vaginal deliveries. A positive association with child birth weight in unadjusted analyses disappeared after adjustments for attained age and parity of the mother. CONCLUSION: Excessive stretching and tearing and multiple deliveries seem to be the main predisposing obstetric factors for symptomatic pelvic organ prolapse. Abdominal delivery emerged as a comparably strong protective factor.

Functional bowel and anorectal disorders in patients with pelvic organ prolapse and incontinence.

OBJECTIVE: The purpose of this study was 1) to determine the prevalence of functional bowel and anorectal disorders as defined by the Rome II criteria in patients with advanced pelvic organ prolapse (POP) and urinary incontinence (UI), and (2) to determine if the extent of prolapse on gynecologic examination is related to the subtypes of constipation or any functional anorectal pain disorder. STUDY DESIGN: Three hundred and two consecutive female subjects presenting to a tertiary urogynecology clinic were enrolled. Demographic, general medical, and physical examination information, including POPQ measurements and a standardized sacral neurologic evaluation, were collected. The prevalence of functional disorders of the bowel, rectum, and anus as defined by the Rome II criteria were collected using the Rome II Modular questionnaire. Relationships of functional disorders to various components of the vaginal examination were reviewed. RESULTS: Thirty-six percent (108/302) met the criteria for constipation, including the following subtypes: 19% outlet constipation, 5% functional constipation, 5% constipation predominant irritable bowel syndrome (IBS), and 7% IBS-outlet. Nineteen percent (56/302) of subjects had IBS or 1 of its subtypes. Functional diarrhea was seen in 6% (17/302), fecal incontinence in 19% (58/302), and anorectal pain disorders in 25% (77/302). After controlling for age, parity, diabetes, constipating medications, and previous pelvic surgery, there were no differences in the prevalence of constipation or any of its subtypes between patients with UI and those with stage 3 or 4 POP. Fecal incontinence was independently associated with UI (adjusted odds ratio [OR] 6.3; 95% CI 2.6-19.1), but not advanced POP. Neither overall stage of POP nor stage of posterior vaginal prolapse was significantly associated with any of the functional bowel disorders, including constipation and its subtypes. Perineal body measurement was significantly longer in patients with outlet type constipation (mean 3.5 +/- 0.6 cm vs 3.1 +/- 0.9 cm, P < .01) and in those with proctalgia fugax (mean 3.4 +/- 1.0 vs 3.1 +/- 0.8, P < .05). CONCLUSION: There is a high prevalence of constipation and anorectal pain disorders in women with urinary incontinence and pelvic organ prolapse. However, patients with stage 3 or 4 pelvic organ prolapse have similar rates of constipation compared with those with urinary incontinence. Constipation and its subtypes are not related to the stage of pelvic organ prolapse. It appears that either constipation is not a significant contributor to prolapse, or constipation contributes equally to the development of both urinary incontinence and pelvic organ prolapse.

True vaginal prolapse in a bitch.

Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition. This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy. Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.

Mitral valve repair for commissural prolapse: surgical techniques and long term results.

OBJECTIVE: The aim of this study was to describe the pattern of lesions responsible for commissural prolapse, the techniques of valve repair and their long-term results. METHODS: Between 1992 and 2004, 128 mitral valve repairs were consecutively performed for commissural prolapse. There were 86 males and 42 females, the median age was 57.5 years (range 14-84 years). Forty-six percent of patients were in NYHA III or IV, mean ejection fraction was 61+/-9.4%. The diagnosis of commissural prolapse was recognized by preoperative echocardiography in 32% of the patients and was revealed by intraoperative inspection of the valve in the other cases. The site of the prolapse was the posteriomedial commissure (n=94), the anterior commissure (n=30) or both (n=4). The aetiologies were: infective endocarditis (n=56), degenerative (n=46), ischemic (n=25), congenital mitral regurgitation (n=1). The commissural prolapse was associated with another mitral valvular lesion requiring a specific treatment in 61 cases (47.7%). An associated procedure was carried out in 45 patients. RESULTS: The operative treatment of the commissural prolapse included: commissural closure 65 (50.8%), leaflet resection 31 (24.2%), transposition or shortening of chordae 19 (14.8%), reimplantation or shortening of papillary muscles 3 (2.3%), and replacement of the commissural area by a partial mitral homograft 10 (8%). In-hospital mortality included three deaths (2.3%) and four patients (3.1%) were reoperated: three pericardial drainages for hemopericardium and one for mediastinitis. During the follow-up, one patient died (0.8%) from myocardial infarction and eight patients (6.3%) were reoperated including six (4.7%) for recurrent mitral regurgitation. After a median follow-up time of 76.9 months (range from 15 days to 160 months), 116 patients (90.1%) were in NYHA I. Echocardiographs showed no or minimal insufficiency in 112 patients (87.5%) and mild or moderate insufficiency in 10 patients (7.8%). CONCLUSIONS: The diagnosis of commissural prolapse is difficult by preoperative echocardiography. The aetiology of the mitral disease is variable (endocarditis, degenerative or ischemic mitral regurgitation). Using a variety of techniques, commissural prolapse can be repaired with excellent clinical and echographic long-term results.

Laparoscopic uterosacral uterine suspension: a minimally invasive technique for treating pelvic organ prolapse.

STUDY OBJECTIVE: To assess the surgical outcomes of laparoscopic uterosacral uterine suspension and describe the surgical technique. DESIGN: Retrospective chart review (Canadian Task Force classification II-3). SETTING: University tertiary medical center. PATIENTS: Twenty-three patients with symptomatic uterine prolapse and desire for uterine preservation who underwent surgical repair. INTERVENTION: Laparoscopic uterine uterosacral uterine suspension. MEASUREMENTS: Preoperative and postoperative evaluations were completed. The stage of pelvic organ prolapse was assessed using the ICS pelvic organ prolapse quantification (POP-Q) examination. Descriptive statistics and paired t testing were used for statistical analysis. RESULTS: Nineteen of 23 patients (82.6%) had preoperative prolapse stage 2 or greater. Nine patients (40.9%) had uterine prolapse beyond the hymen. After operation there were significant improvements in the stage of prolapse (2 vs 0, p<.01). The POP-Q scores for point C and D were significantly further away from the hymen after operation than compared with the preoperative values (-0.6 vs -7.8, and -5.0 vs -8.6; p<.01) respectively. There were no intraoperative complications. The estimated blood loss (mean+/-SD) was 111.5+/-139.4 mL. The hospital stay (mean+/-SD) was 2.2+/-1.7 days. None of the patients had symptomatic prolapse during the mean follow-up of 15.9 months. CONCLUSION: Laparoscopic uterine suspension appears to be a safe and effective treatment option for uterine prolapse in patients who desire uterine preservation.

Joint hypermobility syndrome and mitral valve prolapse in panic disorder.

OBJECTIVE: The purpose of this study is to test the association between joint hypermobility syndrome (JHS) and panic disorder (PD) and to determine whether mitral valve prolapse (MVP) modifies or accounts in part for the association. METHOD: A total of 115 subjects are included in this study in three groups. Group I (n = 42): panic disorder patients with MVP. Group II (n = 35): panic disorder patients without mitral valve prolapse. Group III (n = 38): control subjects who had mitral valve prolapse without any psychiatric illness. Beighton criteria were used to assess joint hypermobility syndrome. Two-dimensional and M-mode echocardiography was performed on each subject to detect mitral valve prolapse. RESULTS: Joint hypermobility syndrome was found in 59.5% of panic disorder patients with mitral valve prolapse, in 42.9% of patients without mitral valve prolapse and in 52.6% of control subjects. Beighton scores was 4.93 +/- 2.97 in group I, 4.09 +/- 2.33 in group II, and 4.08 +/- 2.34 in group III. There was no significant difference between groups according to Beighton scores. CONCLUSION: We did not detect a statistically significant relationship between panic disorder and joint hypermobility syndrome. Mitral valve prolapse and joint hypermobility syndrome are known to be etiologically related and we suggest that mitral valve prolapse affects the prevalence of joint hypermobility syndrome in the panic disorder patients.

Echocardiographic assessment of the mechanisms of correction of bileaflet prolapse causing mitral regurgitation with only posterior leaflet repair surgery.

Recent data suggest that posterior leaflet repair alone corrects mitral regurgitation in patients with bileaflet prolapse and normal anterior chordae. The purpose of this study was to use echocardiography to define the anatomic differences between posterior and bileaflet prolapse and to determine if posterior leaflet repair alone leads to correction of bileaflet prolapse. We studied patients who underwent quadrangular resection of the posterior mitral valve leaflet to treat bileaflet prolapse (group I, n = 20) or isolated posterior leaflet prolapse (group II, n = 20). Echocardiographic characteristics were compared before and after the procedure. There were no differences in the left ventricular end-diastolic or end-systolic dimensions or function between the 2 groups. However, anterior leaflet length was greater in patients with bileaflet prolapse (3.3 +/- 0.6 cm vs 2.6 +/- 0.4 cm, p = 0.003). In group I, posterior leaflet repair changed anterior leaflet displacement from -0.8 +/- 0.2 to 0.5 +/- 0.4 cm (p <0.001) and posterior leaflet displacement from -0.8 +/- 0.3 cm below to 0.5 +/- 0.4 cm (p <0.001) in front of the mitral annular plane. In group II, anterior leaflet displacement was unchanged from 0.2 +/- 0.1 to 0.3 +/- 0.2 cm (p = 0.22), whereas posterior leaflet displacement changed from -0.7 +/- 0.2 to 0.4 +/- 0.2 cm (p <0.001). Thus, patients with bileaflet prolapse and no ruptured chords have excessive anterior leaflet length. In such patients, posterior leaflet repair alone corrects anterior and posterior leaflet prolapse.

Analysis of indications for surgical closure of subarterial ventricular septal defect without associated aortic cusp prolapse and aortic regurgitation.

Subarterial ventricular septal defect (VSD) is relatively common in Orientals. We reviewed the outcome of 214 patients (137 males) who were followed for 8.6 +/- 5.2 years (range 0.1 to 24.3) and addressed the issue regarding the necessity and optimum timing of closing subarterial defects before development of aortic valve deformities. Demographic data, transthoracic and transesophageal echocardiographic findings, cardiac catheterization results, and operative findings were reviewed. Kaplan-Meier actuarial analysis was performed to assess the development of aortic valve complications over time. Seventy-five patients with heart failure and pulmonary hypertension underwent surgical closure of VSD at the age of 2.4 +/- 2.9 years. No patient had aortic cusp prolapse before operation and none developed aortic cusp prolapse or aortic regurgitation (AR) on follow-up. In contrast, of the 139 asymptomatic patients managed conservatively, 102 (73%) developed aortic cusp prolapse, 78% of whom (80 of 102) developed AR. The prevalence of aortic cusp prolapse and AR at 1, 5, 10, and 15 years old was 8%, 30%, 64%, and 83%, and 3%, 24%, 45%, and 64%, respectively. Significant prolapse or AR prompted surgical closure of VSD with (n = 22) or without (n = 26) valvoplasty in 48 of 102 patients (47%). The size of the VSD was significantly larger in patients with heart failure (9.6 +/- 3.3 mm) or aortic cusp prolapse (11.7 +/- 4.1 mm) compared with those without heart failure (4.5 +/- 1.4 mm, p <0.001). All patients with aortic cusp prolapse and all but 1 with heart failure had a defect size of > or =5 mm. In conclusion, subarterial VSD of > or =5 mm should be closed as early as possible to prevent development of aortic cusp prolapse and AR. Asymptomatic patients with small defects <5 mm could be managed conservatively.

The incidence of genital prolapse after the Burch colposuspension.

OBJECTIVE: Our objective was to determine the incidence of postoperative genital prolapse after the Burch colposuspension and to identify risk factors for the development of subsequent prolapse. STUDY DESIGN: The charts of 131 patients who had a Burch colposuspension performed by the senior author (S.L.S.) between 1977 and 1986 were reviewed at the Urodynamic Unit of St. George's Hospital, London. Emphasis was placed on the degree of genital prolapse on clinical examination and whether further surgery was required to correct the prolapse. RESULTS: Thirty-five patients (26.7%) required a total of 40 operations to correct genital prolapse after colposuspension. At 20 operations, more than one procedure was required to correct combined prolapse. The patient's age, weight, parity, menopausal status, and prior pelvic surgery did not affect the incidence of postoperative prolapse. The only preoperative risk factor identified was the presence of a large cystocele. CONCLUSION: Postoperative genital prolapse is a significant complication of the Burch colposuspension. It is unclear whether this is due to a disruption of the vaginal axis or to an intrinsic weakness of the pelvic floor in these women.

Risk factors and infant outcomes associated with umbilical cord prolapse.

OBJECTIVES: Our goal was to identify risk factors associated with umbilical cord prolapse and to review the perinatal outcome of cases of cord prolapse. METHODS: During the study years 77 cases were identified retrospectively. Associations between cord prolapse and potential risk factors were evaluated by means of the odds ratio. RESULTS: Of the 77 fetuses with umbilical cord prolapse 9.1% had a fetal weight of < 2500 gas compared with 9.4% for fetuses in control group (P > 0.05). The umbilical cord prolapse occurred in association with vertex presentation 66 times (85.7%), breech presentation nine times (11.7%) and transverse presentation two times (2.6%). The occurrence of breech presentation among the control cases was 2.6%, and that of transverse lie was 1.7% (P < 0.01). Case mothers were 1.6 times more likely to be multiparas compared with the control group (P < 0.01). The perinatal mortality rate was 39/1000. CONCLUSIONS: Our study showed that abnormal fetal presentation and multiparity are associated with an increased risk of umbilical cord prolapse. The association of risk of cord prolapse with low birth weight was statistically insignificant (P > 0.05). We suggest that the cesarean delivery decreased the risk of perinatal mortality among cases of cord prolapse.

Umbilical cord prolapse and perinatal outcomes.

OBJECTIVES: To determine obstetric risk factors and perinatal outcomes of pregnancies complicated by umbilical cord prolapse. METHODS: A population-based study was performed comparing all deliveries complicated by cord prolapse to deliveries without this complication. Statistical analysis was performed using multiple logistic regression models. RESULTS: Prolapse of the umbilical cord complicated 0.4% (n=456) of all deliveries included in the study (n=121,227). Independent risk factors for cord prolapse identified by a backward, stepwise multivariate logistic regression model were: malpresentation (OR=5.1; 95% CI 4.1-6.3), hydramnios (OR=3.0; 95% CI 2.3-3.9), true knot of the umbilical cord (OR=3.0; 95% CI 1.8-5.1), preterm delivery (OR=2.1; 95% CI 1.6-2.8), induction of labor (OR=2.2; 95% CI 1.7-2.8), grandmultiparity (>five deliveries, OR=1.9; 95% CI 1.5-2.3), lack of prenatal care (OR=1.4; 95% CI 1.02-1.8), and male gender (OR=1.3; 95% CI 1.1-1.6). Newborns delivered after umbilical cord prolapse graded lower Apgar scores, less than 7, at 5 min (OR=11.9, 95% CI 7.9-17.9), and had longer hospitalizations (mean 5.4+/-3.5 days vs. 2.9+/-2.1 days; P<0.001). Moreover, higher rates of perinatal mortality were noted in the cord prolapse group vs. the control group (OR=6.4, 95% CI 4.5-9.0). Using a multiple logistic regression model controlling for possible confounders, such as preterm delivery, hydramnios, etc., umbilical cord prolapse was found to be an independent contributing factor to perinatal mortality. CONCLUSIONS: Prolapse of the umbilical cord is an independent risk factor for perinatal mortality.

The prevalence of mitral valve prolapse in children with anxiety disorders.

Studies in adults have suggested a comorbidity of mitral valve prolapse and anxiety disorders, especially panic disorder. The nature of the association between these disorders is yet unclear. In the last years, case studies have appeared, reporting on the comorbidity of anxiety disorders and mitral valve prolapse in children. The present study evaluated the prevalence of mitral valve prolapse in children with anxiety disorders as compared to normal controls. The study group consisted of 52 children, 6-18 years old, with a diagnosis of panic disorder (9.6%), separation anxiety disorder (65.4%) and/or overanxious disorder (61.5%). Fifty-one normal age- and gender-matched healthy children served as controls. All participants were evaluated for the presence of mitral valve prolapse by cardiac auscultation and echocardiography. None of the 52 children with anxiety disorder and one of the 51 control children (1.96%) had mitral valve prolapse. There appears to be no association between childhood anxiety disorders and mitral valve prolapse. Whether children with panic disorder proper show a greater prevalence of mitral valve prolapse remains an open question. Implications to the association of mitral valve prolapse and panic disorder are discussed.
