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.

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.

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.

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.

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.

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.

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.

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.

[Comparative evaluation of the accumulation of bacterial plaque on human enamel and on the surfaces of various materials used for esthetic fillings]. / Valutazione comparativa dell'accumulo della placca batterica sullo smalto umano e sulla superficie di diversi materiali per otturazione estetica.

Accumulation of the bacterial plaque on materials used for cosmetic fillings was comparatively evaluated against that on the dental enamel of males and females aged 40-50 yr using the index of Löe & Sillness. Significantly greater accumulation was noted on filling materials.

[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.

[Variations in the taste function of smokers]. / Variazioni della funzione gustativa nei soggetti fumatori.

Cigarette smoke is linked to many pathologies and also affects a very important aspect of human physiology that is taste. In fact already in the past years, researchers have worked on this phenomenon and have come to the conclusion that smoke influences the perception of bitter taste. In our study we researched the detection and identification threshold in thirty smokers, for the citric acid, quinine, sodium chloride and saccharose, and it turned out that smokers suffer a raise in quinine identification and sodium chloride detection and identification threshold. On the basis of the results obtained with sodium chloride, a theory on hypertension etiopathogenesis is suggested.

[Standard electromyographic and kinesiographic parameters in a sample of healthy population]. / Ricerca parametri elettromiografici e kinesiografici standard in un campione di popolazione sana.

The authors have examined through the electromygraphic-kinesiographic system provided, the mandibolar movements and the electric activity of the masseter and temporal muscles of group of 25 subjects, aged 22-25 (15 women and 10 men), with complete natural dentition, whose history and clinical examination of cranio-mandibular disorders were negative. The aim of the study is to analyse the values come out by these instrumental researches and to compare them with the already existing literature, trying to obtain standard data of "normality", to be used as comparative and diagnostic parameters for this age range and, on the other hand, as a further method of evaluation for electromyiografic-kinesiographic and electromyiographic analysis of subjects suffering from algic-dysfunctional pathology of the cranio-mandibular apparatus. The analysed champion of healthy subjects, with symmetrical electromyiographic normal values (temporan muscles 0.5-2.5 microvolts, masseter muscles 0.5-2.0 microvolts), presents physiological mandibular movementes along the three space axes: furthermore the results outlined by the existing literature, according to which the female champion has a lower muscular electric potential and mandibular dinamic paths than the male champion, are confirmed. The authors point out the importance of computerised clinical research, not only to get data, but also to store them and to be able to compare them in long term.

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.
