RESUMO

INTRODUCTION: Herlyn-Werner-Wunderlich syndrome , a rare Müllerian ducts congenital disease, is characterized by a diphtheritic uterus, blind hemivagina, and ipsilateral renal agenesis. Diagnosis is at young age by ultrasound and magnetic resonance imaging, and the prognosis is good. Usually, complications evolve endometriosis and secondary pelvic inflammation. CASE REPORT: A 40-year-old female patient, Brazilian, white, primigravida, diagnosed at 30 years with a didelphic uterus on ultrasound, and 4 years later, with a left ovarian endometrioma, multiple ovarian cysts, and left renal agenesis on magnetic resonance imaging. Subsequently, due to dyspareunia and a feeling of swelling, the patient underwent transvaginal ultrasound with bowel preparation, and a hematocolpos was found and Herlyn-Werner-Wunderlich syndrome was suspected; 10 years after the diagnosis she had a planned pregnancy. She presented frequent contractions following the 15th week of pregnancy and fortunately there were no complications or premature labor. Labor was inducted at 40 weeks and 6 days without progress and a cesarean section was indicated and performed without complications. Herlyn-Werner-Wunderlich syndrome often goes unnoticed, leading to inadequate treatment. Individuals with Herlyn-Werner-Wunderlich syndrome commonly face fertility issues, such as high miscarriage rate (21-33%), and obstetric complications, such as spontaneous abortions (40% risk), intrauterine growth restriction, postpartum hemorrhage, increased fetal mortality, preterm delivery (21-29%), and elevated rates of cesarean sections. In addition, there is higher susceptibility of developing endometriosis, especially with hemivaginal obstruction, and pelvic adhesions. CONCLUSION: Early diagnosis enables timely treatment and, consequently, fewer complications. Still, when these factors are absent, vaginal birth may still be possible. The true prevalence and incidence of complications related to Herlyn-Werner-Wunderlich syndrome are still unknown.

RESUMO

OBJECTIVES: To undertake a systematic review to assess the accuracy of fetal MRI in diagnosis of non-CNS congenital anomalies of the fetal body in comparison with antenatal ultrasound when correlated to postnatal diagnosis. METHODS: Searches were conducted from electronic databases, key journals and reference lists for eligible papers. Inclusion criteria was original research studies comparing the diagnostic results of antenatal ultrasound, fetal MRI and final postnatal diagnosis via imaging, surgery or post-mortem testing. Studies of CNS anomalies were excluded. Studies were assessed for risk of bias by two reviewers working independently and data was then extracted by a single reviewer. RESULTS: 12 studies were included with a total of 361 eligible patients who underwent USS and MRI and had a postnatal diagnosis. USS alone had a diagnostic accuracy of 60.6% whereas MRI had an improved diagnostic accuracy of 86.4%. The overall odds ratio was 0.86 (CI 0.202-1.519 and p-value < 0.01). CONCLUSION: Fetal MRI makes a significant contribution to accurate diagnosis of congenital abnormalities of the fetal body; especially in genito-urinary anomalies. More research is needed to improve the evidence base for the role of fetal MRI in diagnosis of congenital anomalies in other body systems.

RESUMO

BACKGROUND: Individuals with congenital solitary functioning kidney (SFK) are at an increased risk of kidney damage. According to some studies, the risk is higher in unilateral kidney agenesis (UKA) than in unilateral multicystic dysplastic kidney (UMCDK). We hypothesized that with early detection of children with UKA and UMCDK, there would be no difference in the presence of hypertension, proteinuria, and reduced glomerular filtration rate (GFR) between UKA and UMCDK. METHODS: Based on a long-term follow-up protocol, we evaluated a cohort of 160 children followed from birth for SFK (84 with UKA and 76 with UMCDK) detected by prenatal or routine neonatal ultrasound screening. Hypertension, proteinuria, and reduced GFR were monitored as markers of kidney damage. We compared the characteristics and outcomes of the subgroups of children with UKA and UMCDK. RESULTS: GFR was reduced in 42 (26.2%) children, of whom 41 showed only mild reduction. Hypertension and proteinuria were found in 22 (13.8%) and 14 (8.8%) children, respectively. Combined kidney damage was present in 57 (35.6%) children. The UMCDK and UKA subgroups differed in GFR at final examination, with UMCDK patients being significantly more likely to have normal GFR compared to UKA patients (82% vs. 67%; p = 0.039). CONCLUSIONS: One third of the children showed signs of SFK damage, albeit mild. Patients with UKA had reduced GFR significantly more often than those with UMCDK, but did not differ in the rates of hyperfiltration injury or congenital anomalies of the kidneys and urinary tract (CAKUT) in SFK.

RESUMO

We present the case of a 6-year-old girl who initially presented with acute pelvic pain, ultimately diagnosed with imperforate hymen leading to hematocolpos. Further investigation revealed additional clinical features including academic struggles, mood swings, and cutaneous findings, prompting consideration of a neurocutaneous syndrome. Magnetic Resonance Imaging (MRI) revealed features consistent with tuberous sclerosis complex (TSC), including radial migration lines in the subcortical white matter and an incidental arachnoid cyst. Notably, this case exhibited a unique presentation with absence of typical TSC findings such as subependymal nodules or cortical tubers. Additionally, precocious puberty, rarely associated with TSC, was observed, suggesting a potential link between hypothalamic lesions and hormonal imbalance. This case underscores the importance of comprehensive evaluation in pediatric patients presenting with seemingly unrelated symptoms, as it may unveil underlying conditions necessitating tailored management strategies.

RESUMO

PURPOSE: Complete androgen insensitivity syndrome (CAIS) and Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) share common clinical features such as female phenotype, vaginal hypoplasia, and primary amenorrhea. Magnetic resonance imaging (MRI) is performed to investigate the cause of primary amenorrhea. However, the MRI features are also similar in both disorders. They are ultimately diagnosed by chromosome testing, but there is a possibility of misdiagnosis if chromosome testing is not performed. This study aimed to identify MRI features that are useful for differentiating CAIS from MRKHS. METHOD: This multicenter retrospective study included 12 patients with CAIS and 19 patients with MRKHS. Three radiologists blindly evaluated the following features: (1) detection of vagina, (2) detection of nodular and cystic structures in the lateral pelvis; undescended testicles and paratesticular cysts in CAIS and rudimentary uteri and ovaries in MRKHS, (3) their location, (4) number of cysts in the cystic structures, and (5) signal intensity on diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) values of the nodular structures. Statistical comparisons were performed using Mann-Whitney U and Fisher's exact tests. RESULTS: Compared with MRKHS, the CAIS group showed significantly detectable vagina, more ventrally located nodular and cystic structures, fewer cysts within the cystic structures, and nodular structures with higher signal intensity on DWI and lower ADC values. CONCLUSIONS: MRI features of detectable vagina, location of nodular and cystic structures, number of cysts within the cystic structures, signal intensity on DWI and ADC values of the nodular structures were useful in differentiating CAIS from MRKHS.

RESUMO

OBJECTIVE: To demonstrate the surgical approach for Müllerian agenesis with bilateral uterine remnants containing functional endometrium. DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: Reproductive surgery unit of a tertiary university hospital. PATIENT: An 18-year-old adolescent was admitted to a tertiary university hospital with complaints of primary amenorrhea and cyclic pelvic pain. Physical examination and magnetic resonance imaging scans suggested a complex Müllerian abnormality. The patient had uterine remnants with bilateral functional endometrium and cervicovaginal agenesis. INTERVENTION: An operation was planned to reconstruct her anatomy by providing a neovagina and anastomosing the uterine remnants. Gonadotropin-releasing hormone analogs were prescribed to suppress her menstruation until the procedure. The operation was performed in the third month after the initial diagnosis. A laparoscopy was conducted, revealing approximately 5 × 6-cm bilateral uterine horns with healthy adnexa. As the first step, a neovagina was created using a modified peritoneal pull-down technique, a standard approach in our clinic. A vaginal incision was made, and a blind vaginal dissection was performed to reach the peritoneum vaginally. Subsequently, an acrylic vaginal mold was inserted. The vaginal orifice was laparoscopically incised using ultrasonic energy with guidance from the inserted vaginal acrylic mold. The orifice was gradually dilated with larger molds. The entire pelvic peritoneum was dissected circularly, and the distal part of the dissected peritoneum was pulled down using four 2.0 Vicryl sutures at 0°, 90°, 180°, and 270° from the opened vaginal orifice. The uterine cavities of both remnants were incised, and two separate Foley catheters were placed in both cavities. A mold with a hole was used to insert the catheters through the vagina. Both catheters were secured in the cavities with Prolene sutures pulled up from the anterior abdominal wall. The next step involved uterine anastomosis. The uterine remnants were unified through continuous suturing, resulting in the formation of a normally shaped uterus. In the final step, the created uterus and neovagina were anastomosed. The patient received instructions on how to perform mold exercises and follow-up care. MAIN OUTCOME MEASURE: Description of laparoscopic management of a rare Müllerian abnormality. RESULTS: The postoperative magnetic resonance imaging scan at 1 month revealed healed unified uterine cavities and vagina. The patient experienced spontaneous menstruation in the second month after surgery and now maintains regular menses with an approximately 9-10 cm functional vagina. Within 3 months after surgery, the visual analogue scale scores for chronic pelvic pain and dysmenorrhea decreased from 9 to 2-3. CONCLUSIONS: Müllerian abnormalities are exceptionally rare, and their spectrum is broad, making it challenging to identify an exact surgical method to restore functional anatomy. Therefore, a customized surgical approach should be designed for each patient on the basis of their unique condition.

RESUMO

RESUMO O anquiloblefáro filiforme congênito é uma rara anomalia congênita, caracterizada por uma fusão palpebral, parcial ou completa, cuja incidência é de 4,4 por 100 mil recém-nascidos. Normalmente, o anquiloblefáro filiforme congênito constitui uma malformação solitária, de ocorrência esporádica, no entanto, pode estar associado a outras malformações. O pediatra possui papel imprescindível para observar as alterações clínicas do recém-nascido e dar orientação para o tratamento adequado. O objetivo deste estudo foi relatar o caso de recém-nascido de termo que teve diagnóstico precoce de anquiloblefáro filiforme congênito associado a outras malformações congênitas, tendo desfeito as aderências em procedimento cirúrgico oportuno, evitando-se a evolução para futuras complicações visuais do paciente.


ABSTRACT Ankyloblepharon filiforme adnatum is a rare congenital anomaly, characterized by partial or complete palpebral fusion, with an incidence of 4.4 per 100,000 newborns. Normally, ankyloblepharon filiforme adnatum constitutes a solitary malformation, with sporadic occurrence, however, it can be associated with other malformations. Pediatricians play an essential role in observing clinical changes in newborns and providing guidance on appropriate treatment. The this study aims to report the case of a full-term newborn who had an early diagnosis of ankyloblepharon filiforme adnatum associated with other congenital malformations.

RESUMO

Las malformaciones müllerianas (MM) son un grupo de anomalías estructurales originadas por fallas de desarrollo de los conductos paramesonéfricos o de Müller durante las primeras 16 semanas de gestación. Un oportuno diagnóstico y una correcta clasificación permiten ofrecer el mejor manejo y diferenciar aquellas pacientes que requieren tratamiento quirúrgico. Se realizó una revisión de la literatura sobre MM en las bases de datos Epistemonikos, SciELO, Cochrane y PubMed. Se rescataron todas las pacientes ingresadas con diagnóstico de MM. En el año 2021, la American Society of Reproductive Medicine publicó un consenso en el que se estandarizó la nomenclatura, se amplió el espectro y se simplificó la clasificación. La clínica es variada, e incluye pacientes asintomáticas cuyo diagnóstico es un hallazgo por imágenes. Los mejores estudios imagenológicos son la resonancia magnética (RM) y la ultrasonografía 3D, dejando la histeroscopia y la laparoscopia (método de referencia) como procedimiento diagnóstico-terapéutico. Se presentan casos clínicos desarrollados durante el primer trimestre de 2022. Recomendamos la utilización sistemática de la RM para el diagnóstico de anomalías complejas u obstructivas del aparato genital. El tratamiento de estas patologías debe ser realizado por ginecólogos endoscopistas expertos, e incluye tratamiento médico y quirúrgico, el cual debe ser enfocado en cada paciente dependiendo del tipo de MM y de los deseos de fertilidad.


Müllerian malformations (MM) are a group of structural anomalies caused by developmental failure of the paramesonephric or Müllerian ducts during the first 16 weeks of gestation. Timely diagnosis and classification allow us to offer the best management and to differentiate those patients who require surgical treatment. Literature review on MM in Epistemonikos, SciELO, Cochrane and PubMed databases. All patients admitted with a diagnosis of MM were rescued. In 2021, the American Society of Reproductive Medicine publishes a consensus where it standardizes the nomenclature, broadens the spectrum, and simplifies the classification. The clinical picture is varied and includes asymptomatic patients whose diagnosis is an imaging finding. The best imaging studies are magnetic resonance imaging (MRI) and 3D ultrasonography, leaving hysteroscopy and laparoscopy (gold standard) as diagnostic therapeutic. Clinical cases developed during the first trimester 2022 are presented. We recommend the routine use of MRI for the diagnosis of complex and/or obstructive anomalies of the genital tract. The treatment of these pathologies should be performed by expert endoscopic gynecologists and include medical and surgical treatment, which should be focused on each patient, depending on the type of MM and fertility desires.

RESUMO

Por su avanzado desarrollo, la ecografia constituye la prueba de imagen de elección en el diagnóstico de las malformaciones durante la etapa prenatal y, en el caso de la correspondiente al tracto genitourinario, dicha técnica no solo permite el diagnóstico de estas, sino que también ofrece información relacionada con los indicadores de mal pronóstico de la función renal. De ahí que la importancia del diagnóstico prenatal por ultrasonografía de estos defectos radica en la posibilidad de realizar acciones preventivas y educativas encaminadas a disminuir la enfermedad renal terminal en la infancia.1,2) No obstante, dichas acciones se pueden ver entorpecidas debido al desarrollo embriológico del aparato genitourinario en diferentes estadios, a la interacción de factores genéticos, epigenéticos y ambientales durante este, así como a su variada expresión fenotípica.2) De lo antes expuesto se deriva la importancia de realizar acciones preventivas de carácter proactivo, es decir, llevar a cabo acciones que superen la actitud reactiva en los individuos ante los problemas, mediante un trabajo de búsqueda capaz de identificar aquellas situaciones desfavorables que puedan incidir de forma negativa en la calidad de vida y que definan una práctica profiláctica para la reducción de los factores de riesgo.3) Este tipo de acción se facilita, en el nivel primario de salud, a través del trabajo que se realiza con los posibles factores que modifican el riesgo preconcepcional genético. Entonces, en qué situación se sugiere actuar por parte del equipo de salud en la atención primaria, con la finalidad de iniciar la nefroprevención desde la etapa prenatal y así contribuir a amortiguar la aparición de dichas anomalías o defectos capaces de afectar de forma negativa la calidad de vida postnatal al no poderse explicar solamente mediante los factores genéticos. Para comenzar se sugiere cumplimentar a cabalidad las medidas tendientes a disminuir la prematuridad y el bajo peso al nacer mediante la captación precoz y el apropiado seguimiento del embarazo; disminuir la incidencia del embarazo en adolescentes, asegurar una nutrición adecuada de la gestante, así como evitar el uso de drogas teratogénicas (alcohol, warfarina, inhibidores de la enzima de conversión, alquilantes, ácido valproico, comitoína, cocaína, etcétera) que pueden ocasionar malformaciones renales. Deberá realizarse un control cuidadoso de la presión arterial, teniendo cuidado de no usar inhibidores de la encima convertidora de angiotensina en casos de hipertensión arterial. Además, fomentar el diagnóstico y tratamiento temprano y adecuado de la infección urinaria, lo cual constituye otra medida para evitar el parto prematuro.2,4 Todo ello basado en que el recién nacido no forma nuevas nefronas y que la nefrogénesis se extiende hasta las 36 semanas de gestación, por lo tanto, los prematuros nacen con menor número de nefronas, lo cual predispone un mayor riesgo de enfermedades renales futuras y de hipertensión arterial. Asimismo, es más susceptible a infecciones, hipoxia por síndrome de dificultad respiratoria, factores que predisponen a una insuficiencia renal aguda y a lesiones renales seculares. En otro sentido, debemos continuar con la administración de ácido fólico a las potenciales gestantes, lo cual contribuye a disminuir la incidencia de defectos de cierre del tubo neural y, en consecuencia, los casos de mielomeningocele, que es la causa más frecuente de vejiga neurógena. Igualmente, el suplemento de vitamina A, cuya deficiencia ha sido implicada en la génesis de las malformaciones renales.4 Otro acápite importante resulta el diagnóstico y tratamiento de las infecciones durante la gestación, ya que pueden ser potencialmente teratogénicas u ocasionar glomerulopatías (lúes, toxoplasmosis, citomegalovirosis, retrovirosis). La infección por estreptococo grupo B deberá ser adecuadamente pesquisada y tratada eliminando una causa frecuente de sepsis neonatal y la probabilidad de insuficiencia renal aguda secundaria. El diagnóstico prenatal de la uropatía mediante la ecografía bidimensional prenatal (fundamental la ecografía estructural del tercer trimestre) conducirá a una evaluación pronóstica de la función renal y a un tratamiento temprano en caso necesario, evitando así el daño renal secundario.2,4 A modo de conclusión, se puede afirmar que la nefroprevención prenatal en la atención primaria de salud, independiente del origen multifactorial de este tipo de defecto congénito y su asociación a síndromes genéticos, se hace posible y, de esta forma, se contribuye de manera satisfactoria a modificar tanto la incidencia al nacimiento como la prevalencia de estos(AU)

RESUMO

A perfusão arterial reversa gemelar é uma anormalidade rara que pode ocorrer em gestações gemelares monocoriônicas. Consiste em uma alteração na circulação fetoplacentária, com desvio de sangue de um dos gemelares para o outro, por meio de anastomoses arterioarteriais e venovenosas na superfície placentária e anastomoses arteriovenosas em áreas de circulação placentária compartilhada. O feto bombeador pode desenvolver insuficiência cardíaca devido ao aumento do débito cardíaco, e o feto receptor, perfundido por sangue pobre em oxigênio por meio do fluxo reverso, é severamente malformado, incompatível com a vida extrauterina. Este artigo apresenta o caso de uma gestação gemelar monocoriônica diamniótica, com manejo clínico conservador. O objetivo é relatar um caso de complicação rara de gestações monozigóticas e revisar condutas para diagnóstico e manejo adequado.(AU)


Twin reverse arterial perfusion is a rare abnormality that can occur in monochorionic twin pregnancies. It consists of an alteration in the fetal-placental circulation, with blood diversion from one of the twins to the other, through arterio-arterial and veno- venous anastomosis on the placental surface and arterio-venous anastomosis in areas of shared placental circulation. The pumping fetus may develop heart failure due to increased cardiac output, and the recipient fetus, perfused by oxygen-poor blood through reverse flow, is severely malformed, incompatible with extrauterine life. This article presents the case of a monochorionic diamniotic twin pregnancy, with conservative clinical management. The objective is to report a case of rare complication of monozygotic pregnancies and review procedures for diagnosis and adequate management.(AU)

RESUMO

PURPOSE: Microtia describes a spectrum of auricular malformations ranging from mild dysplasia to anotia. A vast majority of microtia patients demonstrate congenital aural atresia (CAA). Isolated microtia has a right ear predominance (58-61%) and is more common in the male sex. Isolated microtia is a multifactorial condition involving genetic and environmental causes. The aim of this study is to describe the phenotype of children with unilateral isolated microtia and CAA, and to search for a common genetic cause trough DNA analysis. METHODS: Phenotyping included a complete clinical examination. Description on the degree of auricular malformation (Weerda classification-Weerda 1988), assessment for hemifacial microsomia and age-appropriate audiometric testing were documented. Computerized tomography of the temporal bone with 3-D rendering provided a histopathological classification (HEAR classification-Declau et al. 1999). Genetic testing was carried out by single nucleotide polymorphism (SNP) microarray. RESULTS: Complete data are available for 44 children (50% was younger than 33 days at presentation; 59.1% boys; 72.7% right ear). Type III microtia was present in 28 patients. Type 2b CAA existed in 32 patients. All patients had a normal hearing at the non-affected side. Genome wide deletion duplication analysis using microarray did not reveal any pathological copy number variant (CNV) that could explain the phenotype. CONCLUSIONS: Type III microtia (peanut-shell type) in combination with a type 2b CAA was the most common phenotype, present in 23 of 44 (52.3%) patients with isolated unilateral microtia. No abnormalities could be found by copy number variant (CNV) analysis. Whole exome sequencing in a larger sample with a similar phenotype may represent a future diagnostic approach.

RESUMO

This is a case of a giant mediastinal teratoma occupying the entire hemithorax, resulting in a complete lung whiteout. Both diagnosis and complete surgical resection of such tumors are considered a challenge, which is what we are reporting in detail in a 24-year-old Syrian woman previously diagnosed with Mayer-Rokitansky-Küster-Hauser syndrome. Here we report the simultaneous incidence of Mayer-Rokitansky-Küster -Hauser syndrome and a mediastinal mature teratoma.

RESUMO

OBJECTIVES: To assess the clinical utility of prenatal chromosomal microarray analysis (CMA) in fetuses with abnormal renal sonographic findings, and to evaluate the association of pathogenic or likely pathogenic copy number variants (P/LP CNVs) with different types of renal abnormality. METHODS: This was a retrospective study of fetuses at 14-36 weeks screened routinely for renal and other structural abnormalities at the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region. We retrieved and analyzed data from fetuses with abnormal renal sonographic findings, examined between January 2013 and November 2019, which underwent CMA analysis using tissue obtained from chorionic villus sampling (CVS), amniocentesis or cordocentesis. We evaluated the CMA findings according to type of renal ultrasound anomaly and according to whether renal anomalies were isolated or non-isolated. RESULTS: Ten types of renal anomaly were reported on prenatal ultrasound screening, at a mean ± SD gestational age of 24.9 ± 4.8 weeks. The anomalies were diagnosed relatively late in this series, as 64% of cases with an isolated renal anomaly underwent cordocentesis rather than CVS. Fetal pyelectasis was the most common renal ultrasound finding, affecting around one-third (34.32%, 301/877) of fetuses with a renal anomaly, but only 3.65% (n = 11) of these harbored a P/LP CNV (comprising: isolated cases, 2.37% (4/169); non-isolated cases, 5.30% (7/132)). Hyperechogenic kidney was found in 5.47% (n = 48) of fetuses with a renal anomaly, of which 39.58% (n = 19) had a P/LP CNV finding (comprising: isolated cases, 44.44% (16/36); non-isolated cases, 25.00% (3/12)), the highest diagnostic yield among the different types of renal anomaly. Renal agenesis, which accounted for 9.92% (n = 87) of all abnormal renal cases, had a CMA diagnostic yield of 12.64% (n = 11) (comprising: isolated cases, 11.54% (9/78); non-isolated cases, 22.22% (2/9); unilateral cases, 11.39% (9/79); bilateral cases, 25.00% (2/8)), while multicystic dysplastic kidney (n = 110), renal cyst (n = 34), renal dysplasia (n = 27), crossed fused renal ectopia (n = 31), hydronephrosis (n = 98), renal duplication (n = 42) and ectopic kidney (n = 99) had overall diagnostic rates of 11.82%, 11.76%, 7.41%, 6.45%, 6.12%, 4.76% and 3.03%, respectively. Compared with the combined group of CMA-negative fetuses with any other type of renal anomaly, the rate of infant being alive and well at birth was significantly higher in CMA-negative fetuses with isolated fetal pyelectasis or ectopic kidney, whereas the rate was significantly lower in fetuses with isolated renal agenesis, multicystic dysplastic kidney or severe hydronephrosis. The most common pathogenic CNV was 17q12 deletion, which accounted for 30.14% (22/73) of all positive CMA findings, with a rate of 2.51% (22/877) among fetuses with an abnormal renal finding. Fetuses with 17q12 deletion exhibited a wide range of renal phenotypes. Other P/LP CNVs in the recurrent region that were associated with prenatal renal ultrasound abnormalities included 22q11.2, Xp21.1, Xp22.3, 2q13, 16p11.2 and 1q21, which, collectively, accounted for 2.17% (19/877) of the fetuses with prenatal renal anomalies. CONCLUSIONS: In this retrospective review of CMA findings in a large cohort of fetuses with different types of renal ultrasound abnormality, the P/LP CNV detection rate varied significantly (3.03-39.58%) among the different types of kidney anomaly. Our data may help in the decision regarding whether to perform prenatal genetic testing in fetuses with renal ultrasound findings. Specifically, prenatal CMA testing should be performed in cases of hyperechogenic kidney, regardless of whether or not the anomaly is isolated, while it should be performed postnatally rather than prenatally in cases of fetal pyelectasis. © 2021 International Society of Ultrasound in Obstetrics and Gynecology.

RESUMO

Fetus in fetu (FIF) is a rare congenital anomaly in which a malformed fetus is incorporated within the body of its twin. It was first described in the late 18th century and has an incidence of 1:500,000 live births. In most cases, the diagnosis is made in infants or young adults. To date, the oldest patient reported in the literature was 47 years old. We describe the case of a 65-year-old patient with FIF, now the oldest reported in the literature. Our patient meets all the diagnostic criteria for FIF, including the presence of a limb in advanced formation inside the lesion. The treatment was surgical excision. FIF should be considered in the differential diagnosis of abdominal masses, typically recognized in infancy. Symptoms arise from mass effects. Surgical resection should be performed due to the potential for malignant transformation.

RESUMO

Introduction: Obstetric ultrasound is part of the screening to select the population at high risk of having a congenital malformation. Considering that fetal defects occur in approximately 2-4 out of every 100 live newborns, and are the cause of 35-40% of perinatal mortality in Chile, it is therefore justified to perform the second trimester ultrasound, which presents a high index prenatal screening (56%), with few false positives. Methods: A retrospective, cross-sectional and descriptive study was carried out, by reviewing 6,385 ultrasound scans, which were performed during one year (June 2020-June 2021), at the Regional Hospital of Talca, where 126 fetuses with suspected malformation were detected. Results: Of the total number of patients evaluated, a congenital malformation rate of 1.9% was detected, with cardiac malformations the most frequent, and diabetes mellitus the main risk factor. Conclusions: Antenatal ultrasound study is essential in the first and second trimesters of pregnancy, followed by a referral to an ultrasound committee, emphasizing early and interdisciplinary management. The frequencies found are similar to those reported in the international bibliography

RESUMO

The aim of this work was to report the occurrence of dicephalus iniodymus monauchenos in a Nellore newborn. A three-days old calf, from in vitro production, with duplication of the head and a history of cesarean birth was attended. On physical examination, the dicephalus, iniodymus and monauchenos, which were almost the same size and shape, had four eyes and four ears. Computed tomography showed the presence of two skulls fused with a common occipital foramen, two nasopharynxes, oropharynxes with the presence of a cleft lip and a cleft palate in the right head, which continued in a single esophagus and a single trachea. At necropsy, the presence of duplication of the cerebrum and cerebellum was observed, with union of the parts in the region of the trapezoid body of the brainstem and continued as a single spinal cord. This study characterizes the clinical, tomographic, and necropsy findings of a dicephalus Nelore neonate.(AU)

RESUMO

OBJECTIVE: In this study, we evaluated factors affecting changes in cervical lordosis after deformity correction and during follow-up period in adult spinal deformity (ASD) patients with severe sagittal imbalance. METHODS: Seventy-nine patients, with an average age of 71.6 years, who underwent long-segment fixation from T10 to S1 with sacropelvic fixation were included. We performed a comparative analysis of the radiographic parameters after surgery (Post) and at the last follow-up (Last). We calculated the Pearson's correlation coefficient and performed multilinear regression analysis to predict independent parameters for Post and Last cervical lordosis (CL), T1 slope (T1S), and thoracic kyphosis (TK). RESULTS: Hyperlordotic changes of -23.3° in CL before surgery was reduced to -7° after surgery, and Last CL had increased to -15.3°. T1S was reduced from 27° before surgery to 14.4° after surgery and had increased to 18.8° at the last follow-up. Through multilinear regression analysis, we found that Post CL and T1S were more significantly affected by the amount of LL correction (p = .045 and .049). The effect of Last T1S was significantly associated with the Last CL; the effect of Last TK, with the Last T1S; and the effect of Post PI-LL, with the Last TK (p < .05). CONCLUSION: The postoperative kyphotic change in CL in ASD patients with preoperative cervical hyperlordosis is not permanent and is affected by drastic LL correction and SVA restoration. To achieve spinopelvic harmony proportional to the difference in LL relative to PI, TK becomes modified over time to increase T1S and CL, in an effort to achieve optimal spine curvature.

RESUMO

OBJECTIVE: To study the efficacy of a novel approach to vaginoplasty in a patient with vaginal aplasia and a preserved cervix. DESIGN: We present the case of a 28-year-old patient who was referred with a history of absent menstruation and vaginal intercourse was absent as well as abnormal development of the internal genitals. The patient underwent a laparoscopic cystectomy in 2012 because of an ovarian cyst and later that year underwent laparotomic supracervical hysterectomy with bilateral salpingectomy because of severe pain caused by a hematometra in their uterine remnant. In the period from 2013 to 2016, multiple pelvic ultrasound examinations revealed a fluid structure in the pelvis. By 2020, the size of the lesion had increased to 10 cm on average. A computed tomography scan and magnetic resonance imaging showed a mucinous lesion in the lower part of the patient's pelvis resembling the cervical origin. No pathology of the urinary tract was found. A laparoscopic approach was chosen to achieve the two main goals of the patient-the possibility of vaginal intercourse and the treatment of the intraabdominal lesion. The procedure started with a vaginal step when the neovagina dissection was performed as in the classical Davydov technique up to the beginning of the dilated cervical remnant. Bilateral ureterolysis was performed laparoscopically to prevent ureteral injury. The peritoneum was widely dissected from both the anterior and posterior surfaces of the uterine cervix, which appeared as a large structure filled with typical cervical mucus. Partial dissection of the sacrouterine and ovarian ligaments on both sides was performed to mobilize the cervix. A transverse incision of the cystically dilated cervix in the cranial part was performed and the edges of the incision were brought down to the introitus of the vagina. The cervicovulvar anastomosis was fixed by separate sutures with Vicryl 2-0. SETTING: The surgery was performed in an inpatient setting equipped with conventional laparoscopic instruments, a 30-degree laparoscope, a high-definition video system, xenon light source, insufflator, irrigator, and bipolar and monopolar energy sources. PATIENT(S): A single patient, mentioned previously. INTERVENTION(S): Surgical vaginoplasty using the preserved cervix. The details are explained in the Design section. MAIN OUTCOME MEASURE(S): Restoration of the normal vaginal anatomy and function. RESULT(S): In the postoperative period, the patient did not have any postoperative complications. The urinary catheter was removed on the first postoperative day. From day 1, the patient was taught to make daily vaginal dilations with a vaginal dilator to maintain normal vaginal depth and width. The patient was discharged on day 3 after surgery. In a 3-month follow-up visit, the patient's vagina appeared normal in size with transverse folds and was very well lubricated because of the natural secretions of the cervical mucosa. The patient had been sexually active by the time of the follow-up visit. CONCLUSION(S): According to a literature search, this was the first published case of a successful neovagina creation through cervicovulvar anastomosis. Although different surgical approaches were widely discussed in previous publications of Fertility and Sterility, such as "Laparoscopic uterovaginal anastomosis in Mayer-Rokitansky-Küster-Hauser syndrome with functioning horn", "Laparoscopy-assisted Ruge procedure for the creation of a neovagina in a patient with Mayer-Rokitansky-Küster-Hauser syndrome", and "Evaluation of amnion in creation of neovagina in women with Mayer-Rokitansky-Küster-Hauser syndrome", which were all variants of vaginoplasty with allograft, vaginal distention (Vecchietti procedure), or the use of native tissues (Davydov technique), our approach could be more feasible in the rare cases of preserved distended cervix because of less induced trauma when compared with that of cervical removal. This is because of the strong and lubricated nature of the cervical epithelium, which is already present and does not require time for epithelization.
