Cervical-length measurement in mid-gestation to predict spontaneous preterm birth in asymptomatic triplet pregnancy.

OBJECTIVE: To assess the predictive value of sonographic cervical-length (CL) measurement in mid-gestation for spontaneous preterm birth (PTB) in asymptomatic triplet pregnancy. METHODS: This was a retrospective study of asymptomatic triplet pregnancies followed at five Italian tertiary referral centers, between 2002 and 2015. CL was measured transvaginally between 18 and 24 weeks' gestation. Pregnancies with medically indicated PTB were excluded. Demographic and pregnancy characteristics of pregnancies complicated by PTB were analyzed and the distributions of CL measurements in these patients were calculated. Logistic regression analysis was performed to assess the association between CL and PTB, adjusted for confounders. Performance of CL measurement in prediction of PTB < 28, < 30 and < 32 weeks of gestation was assessed. RESULTS: A total of 120 triplet pregnancies were included in the final analysis. Median CL was 35 (interquartile range (IQR), 29-40) mm measured at a median gestational age of 20 + 2 (IQR, 20 + 0 to 23 + 4) weeks. Overall, 23 (19.2%), 17 (14.2%) and eight (6.7%) patients had a CL < 25, < 20 and < 15 mm, respectively. Spontaneous PTB < 32 weeks occurred in 41 (34.2%) cases, < 30 weeks in 23 (19.2%) and < 28 weeks in 12 (10%) cases. CL < 15 mm was significantly more frequent in the group of patients who delivered < 28 (P = 0.03) and < 30 (P = 0.01) weeks' gestation, compared with those who delivered after 28 and after 30 weeks, respectively, while CL < 20 mm was more common in triplet pregnancies with delivery < 32 weeks compared with those delivered ≥ 32 weeks (P = 0.03). Logistic regression analysis was possible only for PTB < 32 weeks due to the small number of cases that delivered < 30 and < 28 weeks. After adjustment for confounders, CL was not significantly associated with PTB < 32 weeks (adjusted odds ratio, 0.97; 95% CI, 0.94-1.01). CL measurement had an area under the receiver-operating characteristics curve of 0.41 (95% CI, 0.20-0.62), 0.41 (95% CI, 0.26-0.56) and 0.42 (95% CI, 0.31-0.54) for the prediction of spontaneous PTB < 28, < 30 and < 32 weeks, respectively. CONCLUSION: CL assessed in mid-gestation is a poor predictor of PTB < 28, < 30 and < 32 weeks' gestation in asymptomatic triplet pregnancy. Copyright © 2017 ISUOG.

Unplanned ultrasound-guided puncture of a tracheal balloon in a premature infant with congenital diaphragmatic hernia.

Temporary tracheal balloons have been shown to improve lung growth in fetuses with severe congenital diaphragmatic hernia. Fetoscopic Endoluminal Tracheal Occlusion (FETO) is performed at 26-28 weeks gestation, and then is removed in utero at 34 weeks gestation at highly specialized centers. In case of preterm labor at a hospital without a specialized team, a number of techniques have been used to remove the balloon, sometimes with death of the newborn. We have successfully performed an ultrasound-guided approach to puncture and remove the tracheal balloon in a premature infant in an emergency setting at birth. After that she was treated for congenital diaphragmatic hernia at our Newborn Intensive Care Unit.

Agenesis of the corpus callosum in fetuses with mild ventriculomegaly: role of MR imaging.

PURPOSE: We evaluated the role of magnetic resonance (MR) imaging in the diagnosis of corpus callosum agenesis - isolated or associated with other anomalies - in fetuses with mild cerebral ventriculomegaly, as depicted at prenatal sonography. MATERIAL AND METHODS: Between January 2005 and March 2007, 33 fetuses with a mean gestational age of 28.9 weeks (range 17-37) and mild ventriculomegaly diagnosed at prenatal sonography were included in this prospective study. All fetuses underwent MR imaging according to the following protocol: half-Fourier T2-weighted images along the three orthogonal plane according to the longitudinal axis of the mother, and subsequently three orthogonal planes were acquired according to the fetal brain. Quantitative image analysis included the size of the transverse diameter of the lateral ventricles, in the axial plane, and the thickness of the adjacent cerebral cortex. Qualitative image analysis included morphology of the lateral ventricles (normal, parallel pattern colpocephaly), signal intensity changes of the fetal brain, interruption of the germinative matrix, agenesis of the corpus callosum (complete/partial) and associated malformations. Postnatal physical examination and diagnostic imaging, as well as surgery, were the standard of diagnosis. RESULTS: Mean axial diameter of the lateral ventricle was 11.6 mm (range 10-15 mm), and mean thickness of the adjacent cerebral cortex was 2.1 mm (range 1.8-3 mm); 23/33 fetuses (70%) showed normal morphology of the lateral ventricles, and 8/33 (24%) showed abnormal morphology (parallel pattern, colpocephaly). The entire corpus callosum was visualised in 20/33 fetuses (60%). In 8/33 fetuses (25%), partial agenesis was diagnosed, whereas in 5/33 (15%), there was hypogenesis. In 6/13 fetuses (46%), isolated corpus callosum agenesis was detected, and two cases of hypogenesis of the corpus callosum were misinterpreted - overestimated in one case and underestimated in another. CONCLUSIONS: MR imaging may prove to be a useful second-line imaging modality in the prenatal diagnosis of corpus callosum agenesis in fetuses with mild ventriculomegaly.

Ultrasonographic measurement of thymus size in IUGR fetuses: a marker of the fetal immunoendocrine response to malnutrition.

OBJECTIVE: To test the hypothesis that intrauterine growth restriction (IUGR) is associated with decreased thymus size in the human fetus. METHODS: The thymus perimeter was measured in 60 consecutive IUGR fetuses at prenatal ultrasound examination. IUGR was defined as an abdominal circumference (AC) <5(th) centile. Sixty controls were identified by selection of the next consecutive appropriately grown fetus of similar gestational age (+/-1 week). To exclude fetal size effects, ratios between thymus perimeter and fetal biometry measurements including biparietal diameter (BPD), AC and femur length (FL), as well as estimated fetal weight (EFW) were compared between IUGR fetuses and controls. RESULTS: The proportion of fetuses with thymus perimeter <5(th) centile for gestation was significantly higher in IUGR fetuses than in controls (58/60 vs. 7/60, P < 0.0001). The mean thymus perimeter/BPD ratio (0.87 +/- 0.20 vs. 1.13 +/- 0.13, P < 0.0001), thymus perimeter/AC ratio (0.28 +/- 0.06 vs. 0.35 +/- 0.03, P < 0.0001), thymus perimeter/FL ratio (1.18 +/- 0.26 vs. 1.51 +/- 0.19, P < 0.001) and thymus perimeter/EFW ratio (0.05 +/- 0.01 vs. 0.06 +/- 0.01, P = 0.02) were significantly lower in IUGR fetuses than in controls. There was a significant positive correlation between the observed-to-expected mean for gestation thymus perimeter ratio and the enrollment-to-delivery interval (r = 0.44, P < 0.001). CONCLUSION: IUGR is associated with a disproportionately small thymus. This supports the hypothesis that thymic involution may be part of the fetal neuroendocrine response to intrauterine starvation.

Assessment of pelvic endometriosis: correlation of US and MRI with laparoscopic findings.

PURPOSE: The purpose of this study was to evaluate the contribution of ultrasound (US) and magnetic resonance (MR) imaging in the diagnosis and local staging of endometriosis by comparing results with laparoscopic findings. MATERIALS AND METHODS: We evaluated 36 consecutive women with suspected or clinically diagnosed endometriosis. Thirty-two out of 36 patients met the following inclusion criteria: transabdominal and endocavitary (US) examination and MR imaging, followed by laparoscopy performed within 2 weeks. US and MR findings were classified based on location, number and morphology (small nodules, large nodules, laminar lesions, cystic lesions, complex lesions, adhesions, cul-de-sac obliteration). RESULTS: Laparoscopy, considered the gold standard, identified 143 lesions in 32 patients. US detected 101 lesions, and MR detected 92 lesions, which were subsequently divided by morphologic appearance. Sensitivity and specificity of the two imaging techniques in the recognition of the different locations were 58% and 25%, respectively, for US and 56% and 50%, respectively, for MR imaging. Results of the two techniques in the different locations examined were similar, with the exception of lesions in the rectovaginal septum, which were better detected by US, and for adhesions and cul-de-sac obliteration, which were more easily detected by MR. CONCLUSIONS: Both US and MR are accurate in the diagnosis of endometriosis. There are no significant differences in staging of pelvic endometriosis between US and MR. US examination is the primary evaluation in cases of suspected disease and for the rectovaginal septum. MR examination is recommended for correct classification in doubtful cases and in cases of suspected extrapelvic lesions and adhesions.

Use of a levonorgestrel-releasing intrauterine device in the treatment of rectovaginal endometriosis.

OBJECTIVE: To evaluate the effectiveness of a levonorgestrel-releasing IUD as therapy for endometriosis of the rectovaginal septum. DESIGN: Prospective therapeutic non-randomized, self-controlled clinical trial analyzing changes in pain symptoms and size of lesions induced by the levonorgestrel-releasing IUD over 12 months. SETTING: Tertiary referral center for treatment of deep endometriosis. PATIENT(S): Eleven symptomatic patients with rectovaginal endometriosis. INTERVENTION(S): A levonorgestrel-releasing IUD was inserted and maintained for 12 months. MAIN OUTCOME MEASURE(S): Severity of dysmenorrhea, pelvic pain, and deep dyspareunia were assessed before insertion of the IUD and throughout treatment. The size of rectovaginal endometriotic lesions were evaluated by using transrectal and transvaginal ultrasonography. RESULT(S): Dysmenorrhea, pelvic pain, and deep dyspareunia greatly improved and the size of the endometriotic lesions was significantly reduced by treatment. CONCLUSION(S): Insertion of a levonorgestrel-releasing IUD alleviates pain and reduces the size of lesions in patients with endometriosis of the rectovaginal septum.

Gonadotropin-releasing hormone agonist treatment for endometriosis of the rectovaginal septum.

OBJECTIVE: This study was undertaken to evaluate the effectiveness of a 6-month course of gonadotropin-releasing hormone agonist treatment for patients with symptomatic endometriosis of the rectovaginal septum. STUDY DESIGN: Fifteen patients with rectovaginal endometriosis and moderate to severe pain symptoms were the subjects of the study. None of these patients had either clinical or objective evidence of ovarian endometriosis, nor was there evidence of any obstructive lesions of the intestine or ureters. All patients were given leuprolide acetate depot at 3.75 mg, 1 ampule intramuscularly every 28 days, and treatment had a planned duration of 6 months. Follow-up evaluations were set every 2 months during the treatment phase and every 3 months thereafter until the completion of 1 year after discontinuation of medical therapy. At each follow-up visit pain symptoms were recorded, and clinical exploration, transvaginal ultrasonography, and transrectal ultrasonography were performed. RESULTS: Two patients stopped the treatment early after the second and fourth leuprolide doses; in both cases the reason was persistence of pain, and both requested a surgical solution. The other 13 patients showed a marked improvement with respect to pain during the 6-month treatment course but had early pain recurrence after drug suspension; 11 of them required further treatment within the first year of follow-up. The failure rate of gonadotropin-releasing hormone agonist therapy to produce 1-year pain relief after treatment discontinuation was 87% (13/15) on an intent-to-treat basis. The endometriotic lesions showed a slight but significant reduction in size during therapy but had returned to the original volume within 6 months after cessation of the gonadotropin-releasing hormone analog treatment. CONCLUSION: Our results suggest that gonadotropin-releasing hormone analogs should not be considered a real therapeutic alternative to surgical treatment for patients with symptomatic endometriosis of the rectovaginal septum, except possibly in a limited and unpredictable number of cases.

Laparoscopic creation of a neovagina in patients with Rokitansky syndrome: analysis of 52 cases.

OBJECTIVE: To evaluate the surgical feasibility and the long-term anatomic and functional results of a new procedure that uses the endoscopic approach to treat uterovaginal agenesis, known as Rokintansky syndrome. DESIGN: Evaluation of surgical feasibility and recording of clinical data over a 12-month follow-up. SETTING: Tertiary referral center for the treatment of female genital malformations. PATIENT(S): Fifty-two patients with vaginal agenesis. INTERVENTION(S): The laparoscopic version of the Vecchietti method was used to create a neovagina. MAIN OUTCOME MEASURE(S): Anatomic success was defined as a neovagina >/=6 cm long, allowing easy introduction of two fingers, within 6 months after corrective surgery. Functional success was considered achieved if the patient reported satisfactory sexual intercourse starting from 6 months after surgery. RESULT(S): The surgical procedure was performed with no major complications and with 100% anatomic success; functional success was obtained in 98.1% of the study population. CONCLUSION(S): In patients with Rokitansky syndrome, the laparoscopic approach for creating a neovagina by the Vecchietti method is simple, safe, and effective.

Xenogeneic transplantation of human spermatogonia.

In the last 3 years, several studies have shown that xenogeneic transplantation of rodent spermatogonia is feasible. The treatment of infertile patients with spermatogenic arrest using the injection of immature germ cells has yielded only poor results. We attempted to establish a complete spermatogenetic line in the testes of mutant aspermatogenic (W/Wv) and severe combined immunodeficient mice (SCID) transplanted with germ cells from azoospermic men. Spermatogenic cells were obtained from testicular biopsy specimens of men (average age of 34.3 +/- 9 years) undergoing infertility treatment because of obstructive and non-obstructive azoospermia. Testicular tissue was digested with collagenase to promote separation of individual spermatogenic cells. The germ cells were injected into mouse testicular seminiferous tubules using a microneedle (40 microm inner diameter) on a 10 ml syringe. To assess the penetration of the cell suspension into the tubules, trypan blue was used as an indicator. Mice were maintained for 50 to 150 days to allow time for germ cell colonisation and development prior to them being killed. Testes were then fixed for histological examination and approximately 100 cross-sectioned tubules were examined for human spermatogenic cells. A total of 26 testicular cell samples, 16 frozen and 10 fresh, were obtained from 24 men. The origin of the azoospermia was obstructive (OA) in 16 patients and non-obstructive (NOA) in 8 patients. The concentration of spermatogenic cells in the OA group was 6.6 x 10(6) cells/ml, and 1.3 x 10(6) cells/ml in the NOA group (p < 0.01). The different spermatogenic cell types were distributed equally in the OA samples, ranging from spermatogenia to fully developed spermatozoa, but in the NOA group the majority of cells were spermatogonia and spermatocytes. A total of 23 testes from 14 W/Wv mice and 24 testes from 12 SCID mice were injected successfully, as judged by the presence of spermatogenic cells in histological sections of testes removed immediately after the injection. However, sections from the remaining testes examined up to 150 days after injection showed tubules lined with Sertoli cells and xenogeneic germ cells were not found. The reason why the two strains of mouse used as recipients did not allow the implantation of human germ cells is probably due to interspecies specificity involving non-compatible cell adhesion molecules and/or immunological rejection.

Laparoscopic creation of a neovagina in a woman with a kidney transplant: case report.

The successful use of Vecchietti's technique for creating a neovagina in a case of Rokitansky syndrome with an associated transplanted kidney is reported. The technique is performed by means of a laparoscopic approach, adapted to the special anatomical situation, in order to avoid renal injuries. The accomplishment of a normally functioning neovagina, with no intra-operative or post-operative complications, proves that this technique can also be applied satisfactorily to this type of patient.

A randomized study of the effects of tibolone and transdermal estrogen replacement therapy in postmenopausal women with uterine myomas.

OBJECTIVE: To evaluate the effects of two types of hormone replacement therapy, an estrogen-progestin combination and tibolone, on uterine myomas in menopausal women. STUDY DESIGN: Thirty-eight menopausal women with one or more uterine myomas were randomized to treatment with a transdermal system continuously releasing estradiol 50 microg/day combined with oral medroxyprogesterone acetate (MPA) 10 mg/day for 12 days/month or tibolone tablets 2.5 mg/day. The scheduled duration of both treatments was 12 months. Physical examination and abdominal/transvaginal ultrasonography were performed before entering the study and at 3, 6 and 12 months of treatment. At each ultrasonography the overall uterine volume was determined as well as the size of each myoma and the endometrial thickness and characteristics. RESULTS: No statistically significant difference was detected between the two groups at any time during treatment. However, within-group analysis showed a significant increase of uterine volume and of myoma number and size in the estrogen-progestin group, whereas no such increase occurred in the patients treated with tibolone. Also, the mean endometrium width increased significantly from baseline to the end of treatment in the estrogen-progestin group, but not in the tibolone group. CONCLUSIONS: Tibolone seems a valid alternative in menopausal patients with uterine myomas as it provides adequate relief from menopausal symptoms and avoids volume increase of the uterus and myomas.

[Titanium joints welded with laser and infrared techniques: comparative analysis of its microstructure]. / Saldature in Titanio con tecniche Laser ed Infrarossi: indagine comparativa della microstruttura.

BACKGROUND: Aim of the study is to compare microstructure of Titanium joints soldered with Laser and Infrared methods by performing SEM analysis, metallography and microhardness evaluation. METHODS: Wax specimens were separated in the middle area corresponding to the joint region, machined and then soldered. 40 Titanium samples were fused and divided in 2 groups of 20 samples each. First group was soldered by laser welding, second one by infrared brazing. SEM analysis and standard metallography were carried out at joined areas and unsoldered surfaces. Microhardness test was performed on longitudinally sectioned samples with 150 g load for 15 second up to 7 mm distance from the joined area. RESULTS: SEM photomicrographs revealed for group 1 a homogeneous metal-joint interface, without microporosities; for group 2 exhibited a distinct demarcation of metal joint interface. Metallography evaluation showed for laser joined samples only the presence of Titanium; infrared joined samples showed in soldered regions also Ni and Cu. Microhardness values detected at the joined surfaces seem to be higher for both considered groups. CONCLUSIONS: Laser joining method with exclusive presence of Titanium seems to be ideal for monometallism; both techniques exhibited microstructural changes in the heated surface layer.

Phantom endometriosis of the sciatic nerve.

OBJECTIVE: To assess the efficacy and diagnostic value of GnRH agonist (GnRH-a) therapy in cases of hidden sciatic nerve endometriosis. DESIGN: Case report. SETTING: Academic tertiary referral center for endometriosis treatment. PATIENT(S): Three patients with cyclic, catamenial sciatica associated with pelvic endometriosis who had electromyographic evidence of sciatic nerve damage but negative computed tomography and magnetic resonance imaging findings. INTERVENTION(S): Monthly administration of the GnRH-a leuprolide acetate plus daily transdermal E2 (25 microg). MAIN OUTCOME MEASURE(S): Relief of pain symptoms and improvement in motor function. RESULT(S): All three patients had clear decreases in pain and partial amelioration of claudication. CONCLUSION(S): Endometriosis of the sciatic nerve may be hard to diagnose with the use of current imaging techniques but may be proved by clinical response to GnRH analogue treatment and may be more frequent than previously thought.

Comparison of transdermal estradiol and tibolone for the treatment of oophorectomized women with deep residual endometriosis.

STUDY OBJECTIVE: To compare the effect of HRT with transdermal estradiol and that of treatment with tibolone in post-menopausal women with residual endometriosis. MATERIALS AND METHODS: 21 women with residual pelvic endometriosis after bilateral oophorectomy with or without hysterectomy were enrolled in the study and were randomized to HRT with transdermal estradiol 50 mg twice weekly (n = 10) associated with cyclic medroxyprogesterone acetate 10 mg daily in women who preserved uterus, and to treatment with tibolone 2.5 mg administered orally once a day (n = 11). The duration of both treatments was scheduled to last at least 12 months. Residual endometriosis was located in the bowel wall in four patients, in the rectovaginal septum in six and deeply in the retroperitoneal pelvic space in six. All women were symptomatic before oophorectomy. RESULTS: All the women were followed for 12 months. No patient suspended therapy because of side effects. Four patients of the estradiol group experienced moderate pelvic pain during treatment compared with only one patient in the tibolone group. One patient in the estradiol group reported severe dyspareunia. CONCLUSION: Although our series is very small, it seems that tibolone may be a safe hormonal treatment for post-menopausal women with residual endometriosis.

Laparoscopic creation of a neovagina in women with pelvic kidney.

Laparoscopic modification of Vecchietti's technique for creating a neovagina was carried out in four women with Rokitansky syndrome and renal anomalies. All four patients had pelvic kidney, and in two it was associated with contralateral renal agenesis. The procedure was specifically modified to reduce the risks inherent in the most difficult step, passing the thread-bearing cutting needle from the abdominal wall to the retrohymenal fossa, through the vesicorectal space. In all patients this was done successfully on the side contralateral to the pelvic kidney or in the hemipelvis in which the ureter was absent. Our experience proves that Vecchietti's technique for creating a neovagina, performed by laparoscopy, is feasible in patients with pelvic kidney, and laparotomy is unnecessary.

Transrectal ultrasonography in the assessment of congenital vaginal canalization defects.

Our aim was to evaluate the reliability of transrectal ultrasonography in the preoperative assessment of congenital vaginal canalization defects. We studied nine patients, six with suspected Rokitansky syndrome and three with suspected complete transverse septum. Before corrective surgery all the patients underwent pelvic examination, transabdominal and transrectal ultrasonography. The ultrasonographic findings were compared with the surgical ones. Transrectal ultrasonography provided an accurate map of the pelvic organs showing the precise distances between the urethra and bladder anteriorly, rectum posteriorly, retrohymenal fovea caudally, and pelvic peritoneum cranially. Transrectal ultrasonography produced a picture that corresponded perfectly with the real anatomical situation. Conversely, abdominal ultrasonography provided inadequate images in six of our nine patients, and magnetic resonance imaging was responsible for a mistaken diagnosis in one patient with suspected transverse vaginal septum. In conclusion, if our results are confirmed in larger series, transrectal ultrasonography could be considered as a diagnostic procedure of choice in the assessment of vaginal canalization defects.

Surgical treatment of recurrent endometriosis: laparotomy versus laparoscopy.

The objective of this study was to clarify which is the better surgical conservative treatment for recurrent endometriosis. We compared two consecutive surgical series at a tertiary care centre for the cure of endometriosis. The patients were 81 women with recurrent endometriosis, 41 reoperated at laparotomy from 1986 to 1991 and 40 reoperated at laparoscopy from 1992 to 1996. Follow-up after the second operation included clinical and ultrasound examinations performed at least once a year to evaluate the recovery of fertility and the reappearance of symptoms and signs of the disease. The cumulative probability of recurrence of dysmenorrhoea (34 and 43 respectively), and the frequency of recurrence of pelvic pain and dyspareunia and of clinical findings suggestive of the disease were not significantly different in the two groups. The rate of recurrence of dyspareunia was higher in the patients operated at laparotomy as was the number requiring a third operation. However, this could be due to the longer follow-up of this group. No significant difference was observed between the cumulative pregnancy rates at 24 months in the two groups (45 in the laparotomy and 54 in the laparoscopy group). We conclude that operative laparoscopy seems as efficacious as conservative surgery at laparotomy in the treatment of recurrent endometriosis.

Bladder endometriosis: deep infiltrating endometriosis or adenomyosis?

OBJECTIVE: To describe the anatomopathologic characteristics of endometriosis infiltrating the bladder detrusor. DESIGN: Descriptive anatomopathologic study. SETTING: Tertiary care center for endometriosis. PATIENT(S): Four patients, aged 22-38 years, who underwent laparotomy for bladder endometriosis. INTERVENTION(S): Surgical excision and pathologic analysis of bladder endometriotic nodules in four patients. MAIN OUTCOME MEASURE(S): Gross and microscopic characteristics of endometriotic nodules. RESULT(S): A nodule of adenomyosis on the anterior wall of the uterus, in continuity with the detrusor lesion, was excised in three patients. In the other patient, bladder endometriosis was continuous with a nodule that infiltrated the left parametrium and extended as far as the posterior leaf of the ipsilateral broad ligament. Microscopically, all of the lesions had a similar histologic pattern: foci of endometriosis scattered in the bladder wall. The main feature was the paucity of endometrial-type stroma, particularly in the bladder submucosa, where glands were almost always dilated and cystlike and were lined by flattened cells. CONCLUSION(S): Analysis of our patients, although it does not pinpoint the pathogenesis of the disease, seems to exclude the hypothesized intraperitoneal origin of endometriotic lesions of the bladder detrusor.

Treatment of adenomyosis-associated menorrhagia with a levonorgestrel-releasing intrauterine device.

OBJECTIVE: To evaluate the efficacy and tolerability of treatment with a levonorgestrel-releasing intrauterine device (IUD) in women affected by adenomyosis-associated menorrhagia. SETTING: Tertiary care center. DESIGN: Prospective, open, noncomparative study. PATIENT(S): Twenty-five women aged 38 to 45 years with recurrent menorrhagia associated with adenomyosis diagnosed at transvaginal ultrasonography participated in this study. INTERVENTION(S): An IUD releasing levonorgestel 20 mcg/day was inserted in each patient within 7 days of the start of menstrual flow. All of the patients were requested to compile a pictorial blood loss assessment chart each month. They underwent clinical and transvaginal ultrasound examinations 3, 6, and 12 months after IUD insertion. MAIN OUTCOME MEASURE(S): Menstrual pattern; serum hemoglobin, ferritin, and iron level changes. RESULT(S): One patient experienced IUD expulsion 2 months after device insertion and another requested removal of the IUD 4 months after insertion because of persistent irregular blood loss. Six months after IUD insertion, amenorrhea was observed in 2 patients and oligomenorrhea in another, spotting occurred occasionally in 7, and 13 had scanty but regular flow. One year of follow-up has been completed by the remaining 23 women: 2 with amenorrhea, 3 with oligomenorrhea, 2 with spotting, and 16 with regular flows. Significant increases in hemoglobin, hematocrit, and serum ferritin have been observed, but the lipid metabolism and clotting variables have remained unchanged. CONCLUSION(S): Our findings indicate that marked and safe relief from adenomyosis-associated menorrhagia can be obtained with the use of a levonorgestrel-releasing IUD.

PIP: The efficacy and tolerability of treatment of adenomyosis-related menorrhagia with a levonorgestrel-releasing IUD were investigated in a prospective study of 25 women recruited from a tertiary care center in Italy. All women reported recurrent menorrhagia of at least 6 months' duration and underwent abdominal and transvaginal ultrasonography, hysteroscopy, and endometrial biopsy before study entry. An IUD releasing 20 mcg/day of levonorgestrel was inserted within 7 days of the onset of menses and follow-up examinations were conducted 3, 6, and 12 months after insertion. 1 woman experienced IUD expulsion 2 months after insertion and another requested removal at 4 months because of persistent irregular blood loss. 6 months after IUD insertion, amenorrhea was observed in 2 women, oligomenorrhea in 1 woman, and occasional spotting in 7 women; the remaining 13 women had scanty but regular periods. At 12 months, 2 women reported amenorrhea, 3 had oligomenorrhea, 2 had spotting, and 16 had regular periods. All menstrual anomalies were well tolerated. IUD-related side effects included headache (24%), breast tenderness (16%), seborrhea or acne (24%), and weight gain (28%). Significant increases in hemoglobin, hematocrit, and serum ferritin were recorded; there were no changes in lipid metabolism or clotting variables. These findings suggest that insertion of a levonorgestrel-releasing IUD represents a viable alternative to hysterectomy in the treatment of adenomyosis. It is speculated that the IUD produces deciduation and subsequent marked hypotrophy of eutopic endometrium.

Pre-operative assessment of bladder endometriosis.

The aim of our study was to verify the reliability of transvaginal ultrasonography in the pre-operative evaluation of bladder endometriosis. Six patients with suspected bladder endometriosis were studied. At referral to our department all six women underwent magnetic resonance imaging (MRI), transabdominal and transvaginal ultrasonography, cystoscopy and descending urography. Subsequently all the women underwent transperitoneal cystotomy and excision of endometriotic lesion at laparotomy. In three patients the bladder endometriotic lesions were continuous with adenomyosis in the anterior uterine wall. Histological examination confirmed the endometriotic nature of bladder nodule in all cases. Abdominal ultrasonography visualized the detrusor neoformation in all the patients but was less precise than transvaginal ultrasonography and MRI in defining the size of the lesions, infiltration of the detrusor and continuity with extravesical lesions. Transvaginal ultrasonography was more accurate and versatile than abdominal ultrasonography. The better image resolution allowed an accurate structural analysis of the bladder wall lesion. Furthermore, involvement of the uterovesical septum could be evaluated and adjacent myometrial infiltration recognized. MRI, although very precise, was less versatile than transvaginal ultrasonography and less accurate in establishing the margins of the lesions as perilesional fibrosis is visualized less clearly than areas containing haematic material. Urography was aspecific but still useful to evaluate the integrity of the upper urinary tract and ureters. In conclusion, in our patients transvaginal ultrasonography was found to be the most accurate technique in the diagnosis of bladder endometriosis.
