RESUMO

OBJECTIVES: To examine the effects of urethroplasty surgery on sexual functions by taking into account age, location of stenosis, length of stenosis and surgical technique parameters. MATERIALS AND METHODS: The prospective study was conducted between January 2015 and August 2017 with 60 cases. Patients were categorized according to age groups (19-65 / 65-75 years), surgery technique and stricture localization and length. Before the urethroplasty operation and postoperative 6th month follow-up, the international index of erectile function (IIEF) form (15 questions), was filled, the relevant domains of sexual function; erectile function (Q1,2,3,4,5,15), orgasmic function (Q9,10) and overall satisfaction (Q13,14) were assessed. RESULTS: The mean age of the cases is 54 ± 13. However, preoperative IIEF, sexual satisfaction and orgasmic function averages of patients with a stenosis segment length of 1-3 cm was found to be significantly higher than that of patients with a stenosis segment length of 4-7 cm. Between stenosis segment length groups, there was no statistical difference in terms of preoperative and postoperative sexual functions. And also, there was no statistically significant change in patients' preoperative and postoperative sexual function scores in terms of localization of stricture and surgery techniques. However, there were statistically significant change in the postoperative IIEF and sexual satisfaction averages according to preoperative averages. CONCLUSION: Our study suggests that urethroplasty surgery itself does not significantly affect erectile function, orgasmic function, and general sexual satisfaction regardless of the type of surgery, localization and length of stenosis. Besides, there was a significant decrease in erectile function in senior adults.

RESUMO

OBJECTIVES: To evaluate protective effects of darbepoetin and tadalafil against ischemiareperfusion injury in ipsilateral and contralateral testicle. MATERIALS AND METHODS: Thirty 3-month-old adult male Wistar-Albino rats were randomly divided into 5 groups (A-E). Sham operation was performed in the first group. In Group B, rats did not received any medication after creating 720 degrees torsion of the left testis. The rats in Group C, D and E received darbepoetin, tadalafil, and darbepoetin/ tadalafil combination 30 minutes after creating 720 degrees torsion of the left testis, respectively. The testes of rats in these three groups were detorsioned at 90 minutes after drug administration. Both testes were removed at 30 minutes after detorsion. RESULTS: There were significant differences between the groups in terms of the degree of histopathological damage, Johnsen score, fibrosis score and caspase-3 immunoreactivity in the torsioned testes (p: 0.000). The results for each parameter in the left testes were significantly better in the darbepoetin / tadalafil combination group. Similarly, there were also significant differences in the contralateral testes (p: 0.000). CONCLUSION: The active substances darbepoetin and tadalafil that were used as a combination had protective effects on both testes and produced out better results in preserving testicular histology. Especially in cases where it is not possible to rescue the torsioned testis, this result was more noticeable in the contralateral testis.

RESUMO

PURPOSE OF INVESTIGATION: To develop a nomogram for estimating nasal bone length (NBL) at 11(+0) - 13(+6) weeks of gestation in 554 consecutive cases and to determine the value of NBL measurement in screening for chromosomal abnormalities. MATERIALS AND METHODS: NBL and crown-rump length (CRL) were examined in 554 fetuses at 11(+0) - 13(+6) weeks' gestation. A nomogram for NBL was developed with data from 479 healthy fetuses in which fetal profile examination was possible. Reference values, including percentiles, weie calculated for each gestational age. RESULT: A linear correlation was noted between CRL and NBL in healthy fetuses at 11(+0) - 11(+6), 12(+0) - 12(+6) and 13(+0) - 13(+6) weeks of gestation. Mean NBL was 2.18 +/- 0.53 mm, 2.46 +/- 0.45 mm, and 2.91 +/- 0.55 mm in healthy fetuses, for these time frames, respectively. NBL increased significantly with CRL from respective means of 2.26 +/- 0.43, 2.60 +/- 0.48, 2.77 +/- 0.43, and 3.16 +/- 0.52 mm at 45 - 54.9, 55 - 64.9, 65 +/- 74.9, and 75 - 84 mm. CONCLUSION: The authors developed a NBL nomogram with data from normal, healthy Turkish fetuses at 11(+0) - 13(+6) weeks of gestation. These reference ranges may prove useful in prenatal screening and diagnosis of syndromes known to be associated with nasal hypoplasia.

RESUMO

We report on a boy born to consanguineous parents, who had hypertelorism, a broad nasal bridge, ridge and tip, bifid nasal tip, cleft alae nasi, broad columella, unilateral preauricular tag, shallow labiogingival sulcus, and bilateral large parietal foramina. Cranial MRI revealed a kinked corpus body and small cerebellar vermis. Molecular analysis uncovered a homozygous c.673C > G (p.Q225E) mutation in ALX4 gene. We compare the relatively mild phenotype in the patient to the more marked phenotype described in other patients with homozygous ALX4 mutations, and to the phenotypes in patients with mutations in other ALX genes.

RESUMO

OBJECTIVE: To evaluate the effects of obesity on the perioperative outcomes in women who underwent vaginal hysterectomy. STUDY DESIGN: In this retrospective cohort study of all women who underwent vaginal hysterectomy for benign disorders at Temple University from January 1997 to December 2002, perioperative indices were compared between 149 obese (BMI ≥ 30 kg/m(2)) and 175 non-obese women (BMI < 30 kg/m(2)). RESULTS: The groups were similar with respect to age, parity, uterine weight, race, surgical indication, and previous pelvic surgery. Among medical conditions, hypertension and diabetes were significantly more common in obese women. Conversion to laparotomy occurred at similar rates in both obese (3.3%) and non-obese (5.7%) women. There was no significant difference between the groups regarding the operative time, length of hospital stay, transfusion rate, perioperative hemoglobin change, and perioperative complications (p < 0.05). CONCLUSION: Obesity does not affect the perioperative outcomes and surgical complications of vaginal hysterectomy.

RESUMO

 OBJECTIVES: The double-J (DJ) stents are commonly used to relieve the ureteral obstruction. Besides several known benefits, some of the patients encounter stent-related morbidities with considerable effects on the quality of life, general health situation, sexual matters, and daily work performance. In this study, we evaluated the effectiveness of tamsulosin/solifenacin combination and mirabegron in reducing DJ stent-related symptoms. MATERIALS AND METHODS: A total of 120 patients with 28cm 4.7fr DJ catheter inserted due to ureteral obstruction were included in this study. Patients were randomly divided into three groups of 40 each; group one received only oral hydration for six weeks; group two received 0.4 mg tamsulosin/10 mg solifenacin, and group three received 50 mg mirabegron. Preoperative and after 6 weeks, the VAPS, OAB-q index, and IPSSs forms were filled. RESULTS: The mean age of the patients was 41.60 ± 12.34 years. There was no significant difference between the groups in terms of preoperative and postoperative VAPS values (p>0.05). There was a significant difference in postop IPSSs values (p:0.001). It was higher in the hydration group than tamsulosin/solifenacin and mirabegron groups. Postoperative IPSS value of the hydration group was 21.78 ± 2.54 while the tamsulosin/ solifenacin and mirabegron groups were 15.6 ± 4.37 and 13.65 ± 4.97, respectively. The use of mirabegron and tamsulosin/solifenacin combination alleviates the LUTSs related with DJ stent. There was also a significant difference between groups in terms of postoperative OAB-q values (p:0.001). Postoperative OAB-q values in the tamsulosin/solifenacin group were significantly higher than the mirabegron group. Postoperative OAB-q value of the hydration group was 29.95 ± 5.21, while the tamsulosin/solifenacin and mirabegron groups were 23.68 ± 4.07 and 18.15 ± 4.1, respectively. Our results also showed that, as a beta-3 adrenergic receptor agonist, mirabegron can improve the OAB-q scores. CONCLUSION: Tamsulosin and solifenacin combination is a significantly good treatment option for reducing LUTS associated with DJ stents. Mirabegron single therapy showed good results in treating LUTS and better results in treating OAB symptoms related with DJ stents than other therapies.


OBJETIVO: El catéter doble J se utiliza para desobstruir el uréter. A parte de los ya conocidos beneficios, algunos pacientes tienen efectos adversos derivados de llevar el catéter que empeoran su calidad de vida, su vida sexual, sus actividades laborales. En este estudio, evaluamos la efectividad de la tamsulosina/solifenacina en combinación y mirabegron en reducir estos síntomas.MATERIAL Y MÉTODOS: Un total de 120 pacientes con cateteres de 28cm/4.7 Ch fueron incluidos en el estudio. Los pacientes se randomizaron en 3 grupos, 40 en cada grupo (un grupo recibio hidratación oral durante 6 semanas, otro grupo tamsulosina 0,4 mg/10 mg solifenacina y el tercero 50 mg mirabegron). VAPS, OAB q index y IPSS cuestionarios se rellenaron en el preoperatorio y a las 6 semanas de tratamiento. RESULTADOS: La mediana de edad fue de 41ª. No había diferencias significativas en los grupos en términos de valores VAPS preoperatorios y postoperatorios. Se evidenció una diferencia significativa en los valores IPSS (p=0,001), ya que fue mas elevado en el grupo de hidratación oral que el grupo de tamsulosina/solifenacina y mirabegron. El valor postoperatorio de IPSS en el grupo de hidratación fue de 22, mientras que en la tamsulosina y mirabegron fue de 15 y 13, respectivamente. El uso de mirabegron y tamsulosina mejora los síntomas tracto urinario inferior por el catéter. También se evidencio una diferencia significativa entre los grupos en términos de OAB-q (p=0,001). Los valores postoperatorios OAB-q en el grupo tamsulosina fueron mas altos que en el grupo mirabegron. El valor OAB-q postoperatorio en el grupo de hidratación oral fue de 29, tamsulosina 23 y mirabegron 18, respectivamente. Nuestros resultados también demuestran que mirabegron puede mejorar los resultados de OAB-q. CONCLUSIONES: Tamsulosina/solifenacina es un buen tratamiento para mejorar los STUI asociados a catéteres. Mirabegon demuestra también buenos resultados en el tratamiento de los síntomas de vejiga hiperactiva relacionados en el catéter mejor que otras terapias.

RESUMO

OBJECTIVE: To compare the pain perception between lidocaine and plain aqueous gel during assessment of postvoid residual volume and the Q-tip test. METHODS: : Patients were randomly assigned to either to 2% lidocaine hydrochloride jelly or plain aqueous gel. The allocated gel was first used to lubricate a catheter that was inserted into the bladder to measure the postvoid residual volume. After removal of the catheter, a cotton swab, coated with the same allocated gel, was advanced to the urethrovesical junction until resistance was felt. The angle of the swab with the horizontal plane was measured at rest and with Valsalva maneuver. Relevant baseline characteristics and the Wong-Baker FACES pain scores (where 0 is for no pain and 5 for worst pain) were compared. RESULTS: After randomization, lidocaine and the plain aqueous gel arms consisted of 69 and 68 women, respectively. Baseline characteristics of the groups were similar. Significantly fewer women in the lidocaine group (62.3%) reported any pain than those allocated to plain aqueous gel (80.9%) (odds ratio 0.39, 95% confidence interval 0.18-0.85). The median pain score was significantly lower in the lidocaine group (1, range 0-5) compared with 2 (range 0-4), P<.001). CONCLUSION: When compared with plain aqueous gel, 2% lidocaine jelly significantly reduces pain perception during evaluation of postvoid residual volume and the Q-tip test. LEVEL OF EVIDENCE: I.

RESUMO

OBJECTIVE: The purpose of this study was to compare perioperative outcome measures of laparoscopic supracervical (LSH) and total hysterectomies (TLH). STUDY DESIGN: This is a retrospective analysis of 1016 LSHs and TLHs at a tertiary medical center between November 1999 and August 2008 in a multivariate logistic regression model. RESULTS: Overall, the groups were similar. Most of the perioperative outcome measures did not differ statistically between the groups. However, the risk of serious complications was higher for TLH (5.8% vs 2.5%; odds ratio [OR], 2.72; 95% confidence interval [CI], 1.35-5.49). Specifically, urinary tract injury occurred more frequently in TLH (2.2% vs 0.5%; OR, 4.75; 95% CI, 1.21-18.56). Conversion to laparotomy was significantly more common in TLH (5.8% vs 4.1%; OR, 2.25; 95% CI, 1.20-4.22). CONCLUSION: In this largest comparison, short-term morbidity of TLH and LSH is overall similar. TLH presents a clinically small, but statistically significant, increased risk of urinary tract injury and conversion to laparotomy.

RESUMO

Medical expulsive therapy (MET) is used especially in distal ureteral stones to reduce colics and decrease the number of endourological surgical interventions. A broad spectrum of agents can be used for the relaxation and the dilatation of the ureter, reducing the intraureteric pressure. Alfa-blockers, calcium channel blockers, phosphodiesterase (PDE) inhibitors, and spasmolytics have been shown as effective in clinical trials on urolithiasis. It is a fact that the urothelium itself, the interstitial cells and the ureteric smooth muscle, have B-beta-2 and beta-3 adrenoreceptors. Stimulation of these receptors results in relaxation of the ureter. A recent beta-3 agonist, mirabegron, is commonly used for overactive bladder nowadays. The mechanism of action is adrenergic agonism that affects with the storage phase of the bladder, without interfering the voiding phase, which is regulated by parasympathetic pathways, commonly muscarinic. Agonism of the beta-3 receptors in the ureter has been shown to decrease the intraluminal pressure. By this mechanism, mirabegron can be thought as an alternative MET agent. Acting through different pathways, and having low adverse effect profile, can be thought as the most striking advantages of mirabegron as a MET. In vitro and in vivo trials should be conducted to support this hypothesis.

RESUMO

OBJECTIVE: To compare two commonly used modifications to the standard Q-tip test for urethral hypermobility: catheter alone and catheter with Q-tip. METHODS: All women referred for the evaluation of urinary incontinence or pelvic organ prolapse were included in the study. A postvoid residual urine was collected on each patient and the angle of the urethra with the horizontal plane was measured at rest and with Valsalva with the Q-tip, catheter alone, and catheter with Q-tip. The test was considered positive if the angle of excursion was 30 degrees or more. RESULTS: In this group of 100 consecutive women with urinary incontinence or pelvic organ prolapse, the mean change in the angle was significantly different from the standard Q-tip test (51 degrees) when catheter alone (35 degrees, P<.001) or catheter with Q-tip modifications were used (44 degrees, P<.001). This difference was due to a significant reduction in the resting and Valsalva maneuver angles with the catheter alone, and a significant decrease only in the Valsalva maneuver angle with the catheter with Q-tip method (P<.001). The percentage of positive tests for the standard Q-tip test (92%) was significantly different from the catheter only method (63%, P<.001), and from the catheter with Q-tip technique (83%, P=.021). The "best match" values of 10 degrees for the catheter alone, and 15 degrees for the catheter with Q-tip methods produce the best equivalent results at this time. CONCLUSION: The use of a catheter, instead of a Q-tip, in the evaluation of urethral hypermobility resulted in reduced angles of excursion from resting to Valsalva maneuver. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: There is conflicting data in the literature regarding the risk of obstetric anal sphincter laceration in patients with a prior laceration. This retrospective chart review seeks to examine the risk of recurrence of obstetric anal sphincter lacerations. METHODS: Patients who sustained anal sphincter laceration at delivery during a 13-year time period from January 1991 to December 2003 were identified from the medical records database at Temple University Hospital. All subsequent deliveries in this group of patients were extracted from the database. Chart review was performed on all subsequent deliveries with specific attention to demographic factors such as age, race, parity, etc., maternal weight, fetal weight, presence of maternal diabetes, and labor characteristics such as induction or augmentation of labor, instrumentation at delivery (vacuum or forceps), use of episiotomy, and degree of perineal laceration. RESULTS: There were 23 451 vaginal deliveries at Temple University Hospital between January 1, 1991 and December 31, 2003. Anal sphincter laceration was noted in 778 subjects. Subsequent deliveries among the group of patients with prior sphincter tears numbered 271. Six (2.4%) patients had recurrence of anal sphincter lacerations, and five of them were third degree lacerations. The rate of recurrent lacerations was not significantly different from the rate of initial lacerations (2.4% vs. 3.3%; odds ratio 0.72, 95% confidence interval 0.33-1.59; p = 0.4). Women who sustained recurrent lacerations were older, more obese (mean weight 92 kg vs. 82 kg), had larger babies (3506 g vs. 3227 g), and were more likely to have episiotomies (66.7% vs. 7%) or instrumental deliveries (33.3 vs. 6.5%). CONCLUSION: Prior anal sphincter laceration does not result in an increased rate of recurrence. Operative vaginal delivery particularly with episiotomy is a risk factor for both initial and recurrent laceration.

RESUMO

OBJECTIVE: To assess the effect of gynecologists' sex on their clinical opinions of hysterectomy. STUDY DESIGN: A survey presenting a case of symptomatic uterine leiomyomas was randomly mailed to the fellows of the American College of Obstetricians and Gynecologists, who were asked to choose either hysterectomy or any uterus-sparing modality for the treatment of the presented case. The effects of gynecologists' sex, age, race, type and year of training, practice type, location and region on their clinical opinions were evaluated with univariate and multivariate logistic regression analysis. RESULTS: Among the 500 potential respondents, 245 (49.0%) responses were complete for analysis. One hundred forty-seven (60.0%) were males, and 98 (40.0%) were females. Hysterectomy choice was not significantly influenced by the gynecologist's sex (77.6% vs. 87.1%; OR 0.51; 95% CI 0.26, 1.01). Univariate logistic regression analysis indicated that only younger age and being in an academic practice significantly decreased the hysterectomy choice among the participants. In the multivariate model, both age (OR 1.66; 95% CI 1.27, 2.19) and academic practice type (OR 0.37; 95% CI 0.14, 0.94) remained independently significant. CONCLUSION: When presented with a case involving symptomatic leiomyomas, gynecologists' sex did not significantly affect their opinion for or against hysterectomy. Only age and practice type were independently significant in this decision making.

RESUMO

OBJECTIVE: A reduction in GSH and an increase in free radicals are observed in inflammatory diseases, indicating oxidative stress. Taurine protects cells from the cytotoxic effects of inflammation. There have been limited studies to date evaluating the effect of taurine in oxidative stress-induced vascular dysfunction and its role in vascular inflammatory diseases. Therefore, we aimed to investigate the effect of taurine on the regulation of vascular tonus and vascular inflammatory markers in rabbit aortae and carotid arteries in oxidative stress-induced by GSH depletion. MATERIALS AND METHODS: Rabbits were treated subcutaneously with buthionine sulfoximine (BSO), GSH-depleting compound and/or taurine. Cumulative concentration-response curves for acetylcholine (ACh), phenylephrine and 5-hydroxytriptamine (5-HT) were constructed with or without Nω-nitro-L-arginine (LNA) in the carotid artery and aorta rings. Immunohistochemical staining was performed for TNF-α and IL-1ß. RESULTS: BSO increased ACh-induced NO-dependent relaxations, phenylephrine-induced contractions in the carotid artery and 5-HT induced-contractions in both the carotid artery and the aorta. BSO decreased EDHF dependent relaxations only in the aorta. ACh-induced NO-dependent relaxations and augmented contractions were normalized by taurine. BSO increased TNF-α expressions in both carotid arteries and aortas, which were reversed by taurine. The BSO-induced increase in IL-1ß was reversed by taurine only in aortae. CONCLUSIONS: Treatment with BSO resulted in vascular reactivity changes and increased immunostaining of TNF-α in mainly carotid arteries in this model of oxidative stress. The effect of taurine on BSO-induced vascular reactivity changes varied depending on the vessel. The inhibition of the increase in TNF-α expression by taurine in both carotid arteries and aortae supports the proposal that taurine has a beneficial effect in the treatment of inflammatory diseases such as atherosclerosis.

RESUMO

OBJECTIVE: To describe the trend in the rate of shoulder dystocia over twenty-four years and identify the risk factors related to the occurrence of dystocia. METHODS: Data was obtained from Maryland State regarding all vaginal deliveries that occurred during six different time periods at five-year intervals since 1979. Trends in the rate of shoulder dystocia, episiotomy, forceps and vacuum delivery were examined. RESULTS: There were a total of 277 974 vaginal deliveries. The overall rate of shoulder dystocia was 1.29% (n = 3590). Induction of labor (adjusted OR 1.2, 1.1-1.3), presence of diabetes (gestational (OR 1.9, 1.7-2.3) or pre-gestational (OR 3.8, 2.7-5.4)), fetal macrosomia (OR 5.1, 4.1-6.3) use of episiotomy (OR 1.6, 1.5-1.8), forceps (OR 1.3, 1.0-1.8) or vacuum (OR 2.3, 2.0-3.9) at delivery were associated with a higher rate of shoulder dystocia. TREND: There was an increase in the rate of shoulder dystocia from 0.2% in 1979 to 2.11% in 2003. In addition there was a drop in the overall episiotomy rate from 73.67% to 23.94% and increase in the use of vacuum from 0.1% to 8.36%. CONCLUSION: The rate of shoulder dystocia has increased by 10 fold during the study period. The use of episiotomy either at spontaneous delivery or instrumental delivery does not appear to decrease the occurrence of shoulder dystocia.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the risk factors involved in failed vaginal hysterectomies. METHODS: Data on all vaginal hysterectomies performed by a single gynecologic surgeon were collected prospectively. Patients requiring pelvic floor repair were excluded. Any procedure converted to the abdominal approach was classified as a failed vaginal hysterectomy and comprised the study group. For every woman who had a failed vaginal hysterectomy, the next 2 women who had successful vaginal hysterectomies immediately after the failed vaginal hysterectomy were taken as controls. Risk factors such as age, parity, body weight, surgical indication, uterine size, presence of leiomyomata in the anterior lower uterine segment, previous pelvic surgeries, abdominopelvic adhesions, location and length of cervix, narrow pubic arch, intraoperative complications such as bleeding requiring transfusion, visceral injury, nulliparity, and adnexal removal were compared between groups. RESULTS: We compared 25 failed vaginal hysterectomies with 50 controls whose procedures were completed successfully through the vagina. Among all the factors gynecologists can assess preoperatively, only the presence of a narrow pubic arch increased the risk of failure for vaginal hysterectomy (odds ratio [OR] 4.1; 95% confidence interval 1.32-12.69). Intraoperative bleeding with transfusion was also found as an independent cause for conversion to laparotomy (OR 7.37; 95% confidence interval 1.75-31.06). CONCLUSION: Women with a narrow pubic arch are not good candidates for vaginal hysterectomy. The most common unpredictable cause for conversion to laparotomy from the vaginal approach is intraoperative bleeding requiring transfusion. LEVEL OF EVIDENCE: II-2

RESUMO

OBJECTIVE: To compare perioperative outcome measures of abdominal and vaginal hysterectomies in obese women. METHODS: We reviewed the charts of all obese women (body mass index more than 30 kg/m(2)) who underwent abdominal or vaginal hysterectomy for benign gynecologic conditions in our institution between 1997 and 2002. Laparoscopically assisted vaginal hysterectomies and hysterectomies with concomitant major pelvic or abdominal surgery were excluded. The rate of operative and postoperative complications, length of hospitalization, operative time, and perioperative change of hemoglobin concentration were analyzed for abdominal hysterectomy and vaginal hysterectomy. RESULTS: The study group consisted of 369 obese women, of whom 189 (51.2%) underwent abdominal, and 180 (48.8%), vaginal hysterectomy. Patient characteristics were statistically comparable between the groups except for uterine weight, which was higher in the abdominal group, and parity, which was greater for women who underwent vaginal hysterectomy (P <.05). After controlling for all the significantly different variables, vaginal hysterectomy resulted in lower incidence of postoperative fever (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.12-0.39), ileus (OR 0.21, 95% CI 0.06-0.75), urinary tract infection (OR 0.21, 95% CI 0.06-0.75), shorter operative time (126.8 +/- 58.7 minutes compared with 109.7 +/- 68.5 minutes) and length of hospital stay (3.5 +/- 1.9 days compared with 1.9 +/- 1.1 days). Seven women (3.7%) who underwent abdominal hysterectomy developed wound infections during their hospital stay compared with none in the vaginal hysterectomy group. CONCLUSION: For obese women, vaginal hysterectomy is superior due to its lower incidence of postoperative fever, ileus, and urinary tract infection and shorter operative time and hospital stay. LEVEL OF EVIDENCE: II-2

RESUMO

OBJECTIVE: The objective of our study was to assess whether prior uterine surgery is a risk factor for adenomyosis. METHODS: Medical records of women who had a hysterectomy for benign conditions between January of 1995 and June of 2002 were reviewed. Women with and without adenomyosis were compared with respect to history of prior uterine surgery, such as cesarean delivery, myomectomy, endometrial ablation, dilation and evacuation, and dilation and curettage. RESULTS: Of 873 completed records available, 412 patients (47.1%) had adenomyosis. Mean age and race distribution were similar between the 2 groups. The group with adenomyosis had significantly higher gravidity (P < .001) and parity (P = .004), but smaller uterine size (P < .001) and uterine weight (P < .001). Univariable analysis for each aforementioned specific surgical procedure did not indicate a significant difference between women with and without adenomyosis. However, history of any prior uterine surgery increased the risk of adenomyosis (48.8% and 41.0%, odds ratio 1.37, 95% confidence interval 1.05-1.79) on univariable analysis. This association remained significant when all of the factors were combined in a multivariable logistic regression model. CONCLUSION: In this study, we found a significantly increased risk of adenomyosis with prior uterine surgery. The absence of significant association with any specific surgical procedure is possibly the result of a smaller number of subjects in each individual group. LEVEL OF EVIDENCE: II-3.

RESUMO

BACKGROUND AND PURPOSE: Despite improvements in noninvasive imaging, some patients with contraindications to iodine-based contrast material still require angiography for the evaluation of carotid stenosis. Our aim was to assess the utility of gadopentetate dimeglumine as an intraarterial contrast agent in common carotid angiography. METHODS: Twelve patients with suspected carotid artery stenosis were enrolled in the study. In addition to the standard injection sequences with iohexol, common carotid arteriograms were obtained after administration of gadopentetate dimeglumine. Neurologic status and vital signs were monitored during and for 6 hours after the examination. For each injection, five independent observers, blinded to the contrast agent used, measured the percentage of carotid stenosis and assessed their confidence in grading the stenosis, the overall quality of the examination, and, in cases of decreased quality, the reason(s) for it. Statistical analysis was done with paired and unpaired t-tests with equal variances. RESULTS: No patient had an adverse clinical outcome, and measurements of carotid artery stenosis showed no statistically significant differences between the gadopentetate dimeglumine and iohexol examinations. Overall image quality and observer confidence in measurements of stenosis on the gadolinium-based studies were slightly but significantly lower than those of identical iodine-based studies. CONCLUSION: Gadopentetate dimeglumine may be an alternative to iodine in selected patients undergoing carotid angiography. Although overall image quality of the gadolinium studies is slightly inferior to that of the iohexol studies, measurements of carotid artery stenosis are similar for the two examinations.

RESUMO

BACKGROUND AND PURPOSE: The ability to identify patients at increased risk for stroke from cerebral hemodynamic ischemia may help guide treatment planning. We tested the correlation between regional cerebrovascular reserve (rCVR) on acetazolamide-challenged single-photon emission CT (SPECT) brain scans and intracranial collateral pathways as well as extra- or intracranial (EC-IC) arterial stenosis on cerebral angiography. METHODS: A retrospective analysis of 27 patients who underwent cerebral angiography and acetazolamide-challenged SPECT brain imaging was performed. With cerebral angiography, the anterior, middle, and posterior cerebral artery (ACA, MCA, PCA) territories were evaluated for patterns of flow, including the ipsilateral carotid or basilar arteries, the circle of Willis collaterals, the EC-IC collaterals, and the leptomeningeal collaterals. With acetazolamide-challenged SPECT, the ACA, MCA, and PCA territories were classified as either showing or not showing evidence of decreased rCVR. Statistical significance was determined by the chi(2) test. RESULTS: Patients with decreased rCVR had significantly greater dependence on either the EC-IC or leptomeningeal collaterals (42%) than did patients without decreased rCVR (7%). Similarly, the cerebral hemispheres with decreased rCVR showed a higher prevalence of 70% or greater stenosis or occlusion of the ipsilateral EC-IC arteries in the anterior circulation (74%) than did hemispheres with no evidence of decreased rCVR (16%), and this difference was also statistically significant. CONCLUSION: Acetazolamide-challenged SPECT brain scanning provides additional information regarding rCVR that is not reliably provided by cerebral angiography.
