A bimanual examination should be performed to exclude abnormal pelvic organs, masses, or uterine impaction and can exclude a large postmicturition urinary residual. Pelvic masses such as ovarian cysts and uterine enlargement greater than 12 weeks size can cause pressure symptoms on the bladder and rectum resulting in urinary frequency or retention; often, the symptoms resolve once the mass has been removed. If pelvic pain is a problem, it is important that a digital examination is performed to assess where the pain originates and in particular to determine trigger points in the levator ani and also tenderness upon palpation of the pelvic organs adjacent to the vagina. Finally, rectal examination is particularly important in the elderly to exclude fecal impaction, which can aggravate urinary incontinence. The method in which symptoms are ascertained may alter the results and self-completed questionnaires seem to be the best. It is important to use reproducible and validated questionnaires as symptoms alone have become the basis of conservative management and have been suggested as indicators for the surgical treatment of pure stress incontinence. In some cases, an obvious cause can be found and treated, thus potentially avoiding the need for further investigations.

However, lower urinary tract and voiding disorder symptoms are notoriously unreliable for an accurate diagnosis [1–3]. Follow-up questionnaires also allow the monitoring of any improvement, placing the patient’s lived experience at the center of ongoing evaluation. It is typically completed by the patient over a number of days prior to the visit to the doctor and records information such as the times of micturition, voided volumes, and fluid intake. However, despite the value of bladder diaries for clinical diagnosis and patient management, an audit by the Royal College of Physicians [5] concluded that bladder diaries are often underused in primary and acute care. Micturition chart records the times of micturition, day and night, for a period of at least 24 hours. Bladder diary records the voided volumes and times of micturition as well as other information, day and night, for at least 24 hours. A large number of additional parameters have been suggested for inclusion in a bladder diary (e. However, there is a balance between collecting enough useful clinical information and minimizing any burden placed on the patient during completion [2]. Over 30 different parameters were considered, but time of void, volume of void, fluid intake, time and amount of incontinence were deemed to be the most important parameters for the utility of a generic bladder diary. Pad use and bladder sensation are also considered important information, as these can have a significant effect on the quality of life of the patient. Several studies explore optimum diary duration [2,10–12] and vary from 24 hours to 7 days in length [7]. Validation should include the “assessment of content, construct and criterion validity, and analysis of reliability and responsiveness” [7]. The time of each event is recorded next to the time covering the full 24 hours for each of the 3 days. In addition to this, there is a column in which to record the bladder sensation score, included within the diary, which allows the patient to describe their sensation of urgency for each micturition. The versatility of the diary is also improved by the inclusion of a further column to record pad use. There are several potential advantages for the use of an electronic bladder diary. Primarily, it facilitates data entry and allows automatic calculation, allowing the immediate review of the essential parameters by the clinician. This has the potential to reduce the workload in busy clinics, reduce calculation errors, and ultimately improve clinical outcomes. A recent pilot study using a sample of 22 patients tested the clinical utility of a handheld electronic diary [15]. The accuracy of the report was 58% when calculated manually from the paper version, compared with 100% accuracy when electronically calculated. In addition, the handheld electronic diary was preferred by 81% of patients over the paper diary with reasons given such as “saves time” and “easier to complete. However, it is recognized that a definitive study in order to test this electronic diary equivalence is required, particularly noting that younger people are more likely to adopt such approaches more readily than the elderly. An electronically based adaptation of a paper- based diary must be shown to produce data that are of at least equivalent or higher reliability. However, all parameters are extremely variable so actually defining what is considered “normal” presents challenges [23–25]. There is also considerable overlap in the range of what may be considered “normal limits” between asymptomatic patients and symptomatic patients [24,26,27]. For example, an older woman of 70 years old is likely to have a higher 426 frequency and smaller volume/void than a 20-year-old woman. In addition to this, independent of age, there is a positive relationship between maximum volume voided during the day (functional bladder capacity) and the total 24 hour volume. Here, a woman who voids a large amount over 24 hours is likely to have a higher frequency and larger volume per void than a woman of similar age who only voids a smaller amount over 24 hours. One hypothesis is that this may be an adaptation to keep the voiding frequency relatively constant by adjusting the bladder capacity to compensate for changes in fluid intake. Nevertheless, these relationships have implications for the clinical interpretation of bladder diaries. As might be expected, even after adjustment, the voiding frequency still increases with both age and voided volume over 24 hours.

We and others have been interested in evaluating the response of intra-atrial conduction to atrial extrastimuli 9 10 11 12 9 during atrial pacing at cycle lengths of 600 and 450 msec purchase 4 mg medrol with visa arthritis pain throughout my body. No conduction delays were noted in response to late coupled extrastimuli in both control patients and those with atrial fibrillation or flutter buy 16 mg medrol mastercard www.arthritis in fingers. However medrol 16mg without a prescription rheumatoid arthritis treatment new zealand, as extrastimuli were delivered with increasing prematurity purchase medrol 4mg with mastercard arthritis in feet during pregnancy, progressive intra-atrial conduction delay occurred. In patients without a prior history of arrhythmias (controls), intra-atrial conduction delays only occurred at coupling intervals just above refractoriness, whereas in those patients with a history of atrial flutter and or fibrillation, conduction delays occurred at much longer coupling intervals (Figs. The differences in response to atrial extrastimuli between control patients and those with atrial flutter or fibrillation are shown in Figures 9-3 and 9-4. While in the control patients there was very little conduction delay up to atrial refractoriness, in patients with a prior history of typical tricuspid-caval isthmus- dependent atrial flutter of fibrillation these atrial conduction delays were seen beginning 50 msec above refractoriness. There are no data available in patients with other macroreentrant atrial tachycardias, although the association with atrial fibrillation suggests they would respond similarly. Of note, when atrial extrastimuli were delivered at a paced cycle length of 450 msec, there was no difference in maximum conduction delay between control patients and those with atrial flutter and fibrillation. This was related to the ability of the control group to achieve shorter coupling intervals, and maladaptation of refractoriness noted in patients with a history of atrial flutter and fibrillation (see subsequent paragraphs). These data, however, suggested that a greater degree of intra-atrial conduction delay in response to relatively late atrial extrastimuli might be a marker for those patients 9 12 predisposed to atrial arrhythmias. S -S represents coupling intervals of extrastimuli to the last beat of an1 2 eight-beat drive at paced cycle lengths of 600 msec for each patient. Stimulation in each patient was performed at the right atrial appendage at a drive cycle length of 600 msec. Progressively premature extrastimuli only produce slight intra-atrial conduction delays of 20 to 25 msec at coupling intervals just above atrial refractoriness. Progressive intra-atrial conduction delay occurs in response to increasing prematurity of extrastimuli. Second, in those patients in whom atrial fibrillation was induced, a greater degree of delay was noted in the triangle of Koch than in those patients in whom no atrial fibrillation was induced. Third, the local electrogram duration in the posterior triangle of Koch was longer in those patients who developed atrial fibrillation in response to atrial stimulation than in those who did not (Fig. These data suggest the prolonged conduction times during high-right atrial stimulation are common to patients with palpitations regardless of whether or not atrial fibrillation is inducible. However, nonuniform anisotropy in the area of the posterior triangle of Koch, and perhaps elsewhere, is quite important since left atrial extrastimuli rarely induce atrial fibrillation or flutter and are rarely associated with intra-atrial conduction delay, particularly in the posterior triangle of Koch (Fig. Additional studies using high-density mapping in both atrial chambers would be critical to decide if any particular site of conduction delay is necessary for initiation of atrial fibrillation and/or flutter. Such studies suggest that the crista forms a functional arc of block in most cases. During slow pacing from these areas, no split potentials are usually seen; however, during rapid pacing from the low posterior right atrium split potentials with opposite activation sequences are 20 21 23 seen. The opposite activation sequence reflects activation caudocranially from the posterior to the crista terminalis and craniocaudally lateral to the crista terminalis. The longest cycle length at which transverse cristal 20 block appeared was increased slightly by propranolol and to a greater extent by procainamide. They suggested that this is the reason that counterclockwise flutter is more frequent than clockwise flutter. However, other factors must be involved since counterclockwise flutter is also induced in transplanted hearts in which the crista 24 terminalis cannot play a role. We have recently evaluated the presence and degree of anisotropy on intra-atrial conduction velocity measured from a high-density (240 poles; 2. Intra-atrial conduction velocity was measured in 16 radii during pacing from the center of the plaque at 600 msec, the fastest rate of 1:1 conduction (F max), and at a rate just above local atrial refractoriness. We found no differences in the degree of anisotropy in patients with chronic atrial P. This reduction was specifically related to a decrease in conduction velocity parallel to fiber orientation (in the so-called rapidly conducting direction) (Table 9-1). All patients showed significant direction-dependent conduction (anisotropy) with the fastest conduction perpendicular to the A-V groove (Fig. The relationship to this pattern of conduction to the activation patterns during atrial fibrillation will be discussed subsequently. In the diagrams, pacing is delivered medial to the potential barrier of the crista terminalis. In A, slow pacing propagates slowly across the crista, resulting in parallel activation on both sides of the crista. At faster rates (B) functional block occurs and activation proceeds around the block. This gives rise to split potentials with opposite activation sequences on either side of the line of block. C depicts a fixed barrier in which conduction never crosses the crista regardless of the rate of pacing. Conduction barriers in human atrial flutter: correlation of electrophysiology and anatomy. An isochronic map and conduction velocities in 16 radii in response to central stimulation from a 240-pole plaque are shown. The isochronic map shows an elliptical pattern with rapid conduction perpendicular to the A-V groove and slow conduction parallel to it. Atrial Refractoriness Changes in atrial refractoriness could and should have a marked influence on development of reentrant arrhythmias. Patients with a history of paroxysmal fibrillation or flutter appear to have different characteristics of 8 9 11 12 refractoriness than in control subjects. Similar observations 10 15 have been noted in patients in whom atrial fibrillation is inducible. Thus, patients with a history of atrial fibrillation and flutter are characterized by a failure of adaptation of high-right atrial refractoriness when short and long cycle lengths are compared. These findings 8 15 are similar to patients in whom atrial fibrillation was induced, as described by our group and Attuel et al. This failure of rate adaptation was noted even though many patients had been in sinus rhythm for days to weeks. They looked at the average induced atrial fibrillation interval at 35 to 40 sites in patients with and without paroxysmal atrial fibrillation during open heart surgery. The average fibrillation interval was 152 ± 3 msec measured at 247 sites in patients with atrial fibrillation and 176 ± 8. The variance of fibrillation at all recording sites was much larger in patients with a history of atrial fibrillation.

We recommend using a delayed absorbable or permanent suture cut to a length of 36–48 in buy medrol australia best thing for arthritis in back. Additionally generic medrol 4mg amex rheumatoid arthritis medication enbrel, when first performing this technique order medrol 16 mg otc rheumatoid arthritis definition pdf, it is recommended to use the extracorporeal approach with a closed knot pusher to secure knot placement buy medrol overnight arthritis foundation neck exercises, as this is the easiest method to both learn and teach. After knots are secured in place, the ureters should be inspected on each side, and an intraoperative cystoscopy should be performed. It is important that cystoscopy is performed prior to the removal of the laparoscopic ports, so that any ureteral compromise can be addressed prior to the completion of the case. For the main operative ports, a line is marked 16 cm cephalad to the inferior margin of the symphysis pubis. A left and right port are then placed 9 cm lateral to this mark once the abdomen has been insufflated. This is to prevent the robot arms from colliding with each other during the procedure. The third arm port is then placed on the left side, 4 cm superior and 3 cm lateral to the camera port. An assistant 5 mm diameter port is placed 5 cm lateral to the camera port [12] (Figure 87. Technique Once the patient is placed in steep Trendelenburg, the robot patient side cart is positioned either between the patient’s legs to align the center of the cart with the patient’s midline (central docking) or aligned alongside the patient for parallel docking. Identification of the uterosacral ligaments can be achieved by placing traction on the vaginal apex 1341 with a probe in the vagina when the uterus is not present or by using a uterine manipulator when the uterus is present. If the later method is indicated, after the uterus has been completely devitalized and prior to colpotomy, upward pressure is placed on the uterine manipulator to help with the identification of the uterosacral ligaments. The complete pelvic course of the ureter is then identified prior to placing sutures. At this level, the uterosacral ligaments are the furthest from the ureters as they are heading toward S3 and the ureters are clearing the pelvic brim. The distal end of the sutures are then passed through the pubocervical and rectovaginal fascia and then incorporated into the vaginal cuff. The vaginal cuff is then tied down after the completion of the cuff closure with polyglactin sutures. A third row of sutures can be used in the instance of elongated uterosacral ligaments. Again as stated in the laparoscopic section, an intraoperative cystoscopy should be performed prior to removal of the ports. The goal of both procedures is to restore normal anatomical support by suspending the apex of the vagina above the level of the ischial spines toward the level of the sacrum without causing any significant distortion to the vaginal axis [13]. In most cases, removing the offending suture(s) will alleviate any obstruction without consequence as long as the surgeon finds the problem intraoperatively [14,15]. Other potential complications include bowel injury, pelvic abscess, dyspareunia, hemorrhage and in rare cases bladder injury, and exposure of permanent sutures into the vaginal lumen [16]. Outcomes Although multiple studies and meta-analyses have been performed evaluating the long-term success of uterosacral ligament suspension when approached vaginally, there are few studies describing the long- term outcomes associated with the laparoscopic and robotic-assisted approach. However, in this study, the uterus was conserved in the laparoscopic approach [17]. In this series, at 6 months follow-up, there was a 100% objective success rate [18,19]. Contrary to many previous studies, this further suggests that the laparoscopic approach is as effective as the traditional vaginal approach. The laparoscopic and robotic approach to performing uterosacral ligament suspension allows the surgeon to have a more global view to inspect the pelvic cavity. Other advantages include the ability to use pneumoperitoneum to access better surgical planes and the also the accuracy of suture placement to achieve an optimal result [18]. The postoperative advantages of this approach are less blood loss, shorter hospital stays, decreased postoperative pain, and the ability to perform adhesiolysis when necessary to obtain a better anatomical result [20]. Although the procedure has been modified through the years, the same principles of using multiple interrupted permanent sutures to attach mesh to the vagina and elevating this up to the anterior longitudinal ligament at the level of the sacrum are still important today. Lane also describes the importance of reapproximating the peritoneum over the synthetic material to avoid interaction of the graft with other pelvic structures. He further emphasized the importance of using mesh to replace the inadequately supported structures that contribute to prolapse as a disorder [22]. Although the gold standard for treatment of apical prolapse is the abdominal sacrocolpopexy due to its effectiveness and availability around the world, many institutions have adopted the more minimally invasive approaches of laparoscopy and robotic-assisted techniques [17,23,24]. Nezhat in 1994 first introduced the laparoscopic sacrocolpopexy, showing its decrease in operative blood loss and, most importantly, patient recovery time while still producing high success rates [23]. Although there is no strict definition of success for this procedure, we and many other authors define a successful procedure based on both the “clinical cure” and “objective anatomic cure” rates [12,29]. Laparoscopic Approach for Sacrocolpopexy Port Placement Traditionally, four laparoscopic ports are placed in the abdomen. A 10 mm suturing port is placed in the left paramedian region, and two additional 5 mm ports are placed. The first accessory port is placed suprapubically, and the second is placed in the right paramedian region [24] (Figures 87. Technique To assist with clearly visualizing the vaginal apex, a probe is placed in the vagina. Next, the peritoneum is dissected away from the vaginal apex anteriorly, exposing the full thickness of the vaginal wall. The dissection is continued one-third down the anterior wall and the space between the rectovaginal fascias. The dissection is continued down to the level of the rectal reflection or further down to the level of the perineal body [31]. If an enterocele is encountered, it should be repaired in a site-specific fashion to avoid suture placement near the area of the graft. The peritoneum overlying the sacral promontory is then incised in a longitudinal fashion and extended down to the right paracolic gutter between the ureter and the colon. The presacral adipose tissue can then be carefully dissected away to reveal the anterior longitudinal ligament. The peritoneum on the sidewalls should be freed enough so that the mesh can be easily retroperitonealized at the end of 1344 the procedure [32]. The anterior leaf of the mesh is sutured using approximately six to ten 2-0 permanent, evenly placed sutures beginning distally toward the vaginal apex. The posterior leaf is sutured in a similar fashion through the rectovaginal fascia. Braided sutures have an increased risk of bacterial colonization, biological tissue response with cellular ingrowth, high tissue reactivity, and suture and mesh erosion [33]. Our institution uses the manual tension approach, where a probe is placed in the vagina to assist with the tensioning of the sacral arm of the mesh. The probe is then removed half way out of the vaginal canal for the placement of the sacral promontory sutures.

Suppose that from a 2 normally distributed random variable Y with mean m and variance s we randomly and independently select samples of size n ¼ 1 buy medrol 4 mg mastercard rheumatoid arthritis trials. Each value selected may be transformed to the standard normal variable z by the familiar formula yi À m zi ¼ (12 discount medrol 16mg line arthritis symptoms. When we investigate the sampling distri- 2 bution of z medrol 4 mg without prescription arthritis pain relief options, we find that it follows a chi-square distribution with 1 degree of freedom buy medrol 4mg amex arthritis in runners knee. That is, 2 2 y À m 2 xð1Þ ¼ ¼ z s Now suppose that we randomly and independently select samples of size n ¼ 2 from the normally distributed population of Y values. If the resulting values of z for each sample are added, we may designate this sum by 2 2 2 y1 À m y2 À m 2 2 xð2Þ ¼ þ ¼ z1 þ z2 s s since it follows the chi-square distribution with 2 degrees of freedom, the number of independent squared terms that are added together. The sum of the resulting z values in each case will be distributed as chi-square with n degrees of freedom. The mathematical form of the chi-square distribution is as follows: 1 1 ðk=2ÞÀ1 Àðu=2Þ f ðuÞ¼ u e ; u > 0 k 2k=2 (12. The variate u is usually designated by the Greek letter chi (x) and, hence, the distribution is called the chi-square distribution. As we pointed out in Chapter 6, the chi-square distribution has been tabulated in Appendix Table F. Further use of the table is demon- strated as the need arises in succeeding sections. The modal value of the distribution is k À 2 for values of k greater than or equal to 2 and is zero for k ¼ 1. The shapes of the chi-square distributions for several values of k are shown in Figure 6. We observe in this figure that the shapes for k ¼ 1 and k ¼ 2 are quite different from the general shape of the distribution for k > 2. We also see from this figure that chi-square assumes values between 0 and infinity. It cannot take on negative values, since it is the sum of values that have been squared. A final characteristic of the chi-square distribution worth noting is that the sum of two or more independent chi-square variables also follows a chi-square distribution. Types of Chi-Square Tests As already noted, we make use of the chi-square distribution in this chapter in testing hypotheses where the data available for analysis are in the form of frequencies. These hypothesis testing procedures are discussed under the topics of tests of goodness-of-fit, tests of independence, and tests of homogeneity. We will discover that, in a sense, all of the chi-square tests that we employ may be thought of as goodness-of-fit tests, in that they test the goodness-of-fit of observed frequencies to frequencies that one would expect if the data were generated under some particular theory or hypothesis. We use it to refer to a comparison ofa sample distribution to some theoretical distribution that it is assumed describes the population from which the sample came. The justification of our use of the distribution in these situations is due to Karl Pearson (1), who showed that the chi-square distribution may be used as a test of the agreement between observation and hypothesis whenever the data are in the form of frequencies. An extensive treatment of the chi-square distribution is to be found in the book by Lancaster (2). Observed Versus Expected Frequencies The chi-square statistic is most appropriate for use with categorical variables, such as marital status, whose values are the categories married, single, widowed, and divorced. The quantitative data used in the computation of the test statistic are the frequencies associated with each category of the one or more variables under study. There are two sets of frequencies with which we are concerned, observed frequencies and expected frequencies. The observed frequencies are the number of subjects or objects in our sample that fall into the various categories of the variable of interest. For example, if we have a sample of 100 hospital patients, we may observe that 50 are married, 30 are single, 15 are widowed, and 5 are divorced. Expected frequencies are the number of subjects or objects in our sample that we would expect to observe if some null hypothesis about the variable is true. For example, our null hypothesis might be that the four categories of marital status are equally represented in the population from which we drew our sample. In that case we would expect our sample to contain 25 married, 25 single, 25 widowed, and 25 divorced patients. The Chi-Square Test Statistic The test statistic for the chi-square tests we discuss in this chapter is " X 2 2 Oi À Ei X ¼ (12. In determining the degrees of freedom, k is equal to the number of groups for which observed and expected frequencies are available, and r is the number of restrictions or constraints imposed on the given comparison. A restriction is imposed when we force the sum of the expected frequencies to equal the sum of the observed frequencies, and an additional restriction is imposed for each parameter that is estimated from the sample. As we will see, the nature of X is such that when there is close agreement between observed and expected frequencies it is small, and when 2 the agreement is poor it is large. Consequently, only a sufficiently large value of X will cause rejection of the null hypothesis. If there is perfect agreement between the observed frequencies and the frequencies that one would expect, given that H0 is true, the term Oi À Ei in Equation 12. Such a result would yield 2 a value of X equal to zero, and we would be unable to reject H0. When there is disagreement between observed frequencies and the frequencies one would expect given that H0 is true, at least one of the Oi À Ei terms in Equation 12. In general, the poorer the agreement between the Oi and the Ei, the greater or the more frequent will be these nonzero values. As noted previously, if the 2 agreement between the Oi and the Ei is sufficiently poor (resulting in a sufficiently large X value,) we will be able to reject H0. When there is disagreement between a pair of observed and expected frequencies, the difference may be either positive or negative, depending on which of the two frequencies is 2 the larger. Since the measure of agreement, X , is a sum of component quantities whose magnitudes depend on the difference Oi À Ei, positive and negative differences must be given equal weight. Dividing the squared differences by the appropriate expected frequency converts the quantity to a term 2 2 that is measured in original units. Adding these individual Oi À Ei =Ei terms yields X ,a summary statistic that reflects the extent of the overall agreement between observed and expected frequencies. P 2 The Decision Rule The quantity ½ Oi À Ei =EiŠ will be small if the observed and expected frequencies are close together and will be large if the differences are large. The decision rule, then, is: Reject H0if X is greater than or equal to the 2 tabulated x for the chosen value of a. Small Expected Frequencies Frequently in applications of the chi-square test the expected frequency for one or more categories will be small, perhaps much less than 1. There is disagreement among writers, however, over what size expected frequencies are allowable before making 2 some adjustment or abandoning x in favor of some alternative test.
