Developmental outcomes of children born through ICSI versus conventional IVF (cIVF) in couples with non-male factor infertility.

STUDY QUESTION: In non-male factor infertile couples, are there any differences in the developmental outcomes between children born through ICSI and conventional IVF (cIVF)? SUMMARY ANSWER: In this preliminary study, ICSI and cIVF seem to have a comparable effect on developmental outcomes after 12 months in children born to non-male factor infertile couples. WHAT IS KNOWN ALREADY: ICSI, an invasive technique, has raised concerns about potential developmental abnormalities in children. Limited data are available regarding the developmental outcomes of ICSI-conceived infants born to non-male factor infertile couples. STUDY DESIGN, SIZE, DURATION: This prospective cohort study involved a follow-up of all children aged 12 months or older who were born from pregnancies resulting from either ICSI or cIVF as part of a previous randomized controlled trial (RCT) (NCT03428919). PARTICIPANTS/MATERIALS, SETTING, METHODS: In the original RCT, 1064 women were randomly assigned to the ICSI or cIVF groups (532 women for each group). Follow-up was conducted with 155 couples (195 children) in the ICSI group and 141 couples (185 children) in the cIVF group. The Vietnamese version of the Ages & Stages Third Edition Questionnaires (ASQ-3) and the Development Red Flags questionnaires were completed by the participants. A total of 141 (90.1%) women (177 children) in the ICSI group and 113 (80.1%) women (145 children) in the cIVF group returned fully completed questionnaires. The primary outcomes were the developmental outcomes based on responses to the ASQ-3 and the Red Flags questionnaire. MAIN RESULTS AND THE ROLE OF CHANCE: The mean age of children at follow-up was 19.5 ± 5.0 months in the ICSI group and 19.3 ± 5.5 months in the cIVF group. The mean height and weight of children in both groups were similar. The overall proportion of children with any abnormal ASQ-3 score did not differ significantly between the ICSI and cIVF groups (16.9% vs 13.1%, P = 0.34). The proportion of children with Red Flag signs was also comparable between the two groups (6.2% vs 9.2%, P = 0.36, ICSI vs cIVF, respectively). LIMITATIONS, REASONS FOR CAUTION: Despite a reasonably high follow-up response rate, there is a potential risk of sampling bias, and overall, the number of children with developmental abnormalities was very small. The study relied solely on questionnaires as screening tools, rather than incorporating additional behavioral observations or physical developmental tests; this may have affected the statistical power and the significance of between-group comparisons. WIDER IMPLICATIONS OF THE FINDINGS: The current findings contribute to the existing evidence and support the comparative safety of ICSI and cIVF regarding early childhood development. However, more extensive and prolonged follow-up data for these children are needed to draw definitive conclusions. STUDY FUNDING/COMPETING INTEREST(S): No external funding was received for this study, and no authors reported conflicting interests. TRIAL REGISTRATION NUMBER: NCT04866524 (clinicaltrials.gov).

Development of children born to women with twin pregnancies treated with cervical pessary or vaginal progesterone: Follow-up of a randomized controlled trial.

INTRODUCTION: Preterm birth is the most common cause of neonatal morbidity and mortality. Women with twin pregnancies and a short cervical length are at high risk for preterm birth. Vaginal progesterone and cervical pessary have been proposed as potential strategies to reduce preterm birth in this high-risk population. Therefore, we aimed to compare the effectiveness of cervical pessary and vaginal progesterone in improving developmental outcomes of children born to women with twin pregnancies and mid-trimester short cervical length. MATERIAL AND METHODS: This was a follow-up study (NCT04295187) of all children at 24 months of age, born from women treated with cervical pessary or progesterone to prevent preterm birth in a randomized controlled trial (NCT02623881). We used a validated Vietnamese version of Ages & Stages Third Edition Questionnaires (ASQ-3) and a red flag questionnaire. In surviving children, we compared the mean ASQ-3 scores, abnormal ASQ-3 scores, the number of children with any abnormal ASQ-3 scores and red flag signs between the two groups. We reported the composite outcome of perinatal death or survival with any abnormal ASQ-3 score in offspring. These outcomes were also calculated in a subgroup of women with a cervical length ≤28 mm (<25th percentile). RESULTS: In the original randomized controlled trial, we randomized 300 women to pessary or progesterone. After counting the number of perinatal deaths and lost to follow-up, 82.8% parents in the pessary group and 82.5% parents in progesterone group returned the questionnaire. The mean ASQ-3 scores of the five skills and red flag signs did not differ significantly between the two groups. However, the percentage of children having abnormal ASQ-3 scores in fine motor skills was significantly lower in the progesterone group (6.1% vs 1.3%, P = 0.01). There were no significant differences in the composite outcome of perinatal death or survival with any abnormal ASQ-3 score in unselected women and in those with cervical length ≤28 mm. CONCLUSIONS: Cervical pessary and vaginal progesterone may have comparable effects on developmental outcomes in children at ≥24 months of age, born to women with twin pregnancies and short cervical length. However, this finding could be likely due to a lack of study power.

[The importance of pulp therapy in deciduous teeth]. / Importance des traitements pulpaires en denture de lait.

Preserving primary teeth is crucial for maintaining the maxillary growth, aesthetics, mastication, and speech and for preventing from abnormal habits. Given the peculiar anatomy of the primary tooth, caries grow faster and more frequently to the pulp. In pediatric dentistry, new methods and enhanced material have been recently released on the market and broadened the field of treatments. In this paper, we review the pulp diseases affecting children and focus on the current root canal therapies that favour the physiological primary tooth loss.

Conserver les dents de lait est essentiel pour assurer la croissance des maxillaires, l'esthétique, la mastication et la phonation ainsi que pour prévenir l'apparition de dysfonctions. Vu les particularités anatomiques des dents de lait, la carie progresse toujours plus rapidement et plus fréquemment jusqu'à la pulpe. L'avènement de nouvelles techniques et de nouveaux matériaux en dentisterie pédiatrique a élargi nos possibilités thérapeutiques. De même, l'interdiction d'utilisation de certains produits a conduit le pédodontiste à devoir trouver des alternatives de traitement. Le but de cet article est de faire le point sur les pathologies pulpaires chez l'enfant et sur les thérapeutiques endocanalaires actuelles.

Treatment algorithm for postoperative upper gastrointestinal fistulas and leaks using combined vicryl plug and fibrin glue.

The incidence of clinically significant anastomotic leaks after upper gastrointestinal surgery is approximately 4 % - 20 %, and the associated mortality can be as high as 80 %. Depending on the clinical presentation, the treatment options are surgery, conservative treatment with external drainage, or endoscopic treatment. This report presents 39 cases of clinically apparent anastomotic leaks or fistulas after surgery for upper gastrointestinal cancers that were treated by endoscopy with insertion of fibrin glue alone (n = 24) or with a combination of Vicryl plug and fibrin glue (n = 15). Thirteen of the 15 patients who underwent Vicryl/fibrin treatments showed complete healing of the anastomotic leak or fistula after one to four sessions. Long-term follow-up results are presented. Postoperative upper gastrointestinal fistulas or anastomotic leaks can be managed successfully with low morbidity by means of endoscopic insertion of Vicryl mesh with fibrin glue, thereby avoiding repeated major surgery and its associated risks.

[The value of postoperative ultrasonography]. / Stellenwert der Sonographie in der postoperativen Phase.

In the early period following surgery, it is very important to reveal any complications. In this article the role of ultrasound in recognizing postoperative complications is demonstrated. Ultrasound findings in typical complications of abdominal surgery such as bleeding, abscess formation, acute cholecystitis, pancreatitis, and postoperative ileus are described. The diagnosis of postoperative bleeding, acute cholecystitis, and ileus is very reliable by ultrasound (sensitivity and specificity >95%). Ultrasonography is inferior to computed tomography in detecting pancreatitis and abscess formation. The guiding of interventions by ultrasound offers additional therapeutic options.

Inferior oblique muscle location after enucleation and evisceration.

PURPOSE: To report the location of the inferior oblique muscle after enucleation without primary attachment of the muscle to the orbital implant and after evisceration. METHODS: Interventional case series. Retrospectively, eight orbital magnetic resonance imaging (MRI) studies were analyzed, four after enucleation and four after evisceration, to assess the position of the inferior oblique muscle relative to the orbital implant and the point of insertion. RESULTS: In the enucleation patients, the inferior oblique muscle was anteriorly displaced and the muscle appeared to insert into an inferior subconjunctival scar mass in three of the four patients. In all four of the evisceration patients, the inferior oblique muscle appeared normally positioned and inserted onto the implant in the normal location. CONCLUSION: Enucleation without suturing of the inferior oblique muscle to the implant is associated with healing in an abnormal anterior location and into an inferior subconjunctival scar mass. Evisceration does not appear to disrupt the normal position or insertion of the inferior oblique muscle.

Results after endoscopic treatment of postoperative upper gastrointestinal fistulas and leaks using combined Vicryl plug and fibrin glue.

BACKGROUND: The incidence of clinically relevant anastomotic leaks after upper gastrointestinal surgery is approximately 4% to 20%, and the associated mortality is up to 80%. Depending on the clinical presentation, the treatment options include surgery, conservative treatment with or without external drainage or endoscopic treatment. METHODS: This report presents nine cases of anastomotic leaks or fistulae after surgery for upper gastrointestinal cancers that were treated by insertion of a Vicryl plug and sealing with fibrin glue. Under sedation, all nine patients underwent endoscopic lavage of the cavity at the site of anastomotic leakage. The entrance to the cavity then was filled with Vicryl mesh and sealed off with fibrin glue. After the procedure, the patients underwent endoscopy and a water-soluble contrast study for assessment of the result. RESULTS: Seven of the nine patients had complete healing of the anastomotic leak or fistula after one to two endoscopic treatments. In one case, the treatment failed immediately because of a large and direct tracheoesophageal fistula. Another patient experienced recurrent intrathoracic abscesses after initial technical success. CONCLUSIONS: Postoperative upper gastrointestinal fistulas or anastomotic leaks can be managed successfully with little morbidity by means of endoscopic insertion of Vicryl mesh with fibrin glue, thereby avoiding repetitive major surgery and its associated risks.

Computed tomographic cholangiography using spiral scanning and 3D image processing.

Volumetric computed tomography (CT) scans ("spiral CT") were performed after intravenous (i.v.) cholangiography followed by additional 3D surface reconstructions of gallbladder and biliary ducts. 34 patients were investigated prior to cholecystectomy. No allergic adverse reactions were observed. The scan time was 24 s. Contrast enhancement in the extrahepatic bile duct and gallbladder were measured. All CT image series were reviewed independently by four experienced physicians (two radiologists, two surgeons) and compared for quality with conventional cholangiography on a three-point scale. The average rating for the demonstration of the biliary tract was significantly better for spiral CT than for conventional cholangiography (p < 0.01). In all cases sufficient contrast was found in the common bile duct (mean 315 HU). 3D imaging was considered to be helpful for intraoperative orientation during laparoscopic surgery.

[MR tomography of colorectal diseases with a negative rectal contrast medium]. / MR-Tomographie kolorektaler Erkrankungen mit negativem rektalen Kontrastmittel.

The potential of the generic kaopectate (Upjohn) as a negative rectal contrast agent in MR imaging was investigated in the assessment of colorectal disease. 45 MR examinations in patients with colorectal disease (colorectal carcinoma 25 patients, inflammatory disease 12 patients, miscellaneous disorders of the colon 8 patients) were evaluated. All examinations were performed with T1 and T2 weighted SE sequences after rectal application of kaopectate. Gd-DTPA enhanced T1 SE sequences were obtained as well. Kaopectate revealed a signal void of the lumen of the large intestine in T1 and T2 weighted SE sequences. Intravenous administration of Gd-DTPA enabled good differentiation of contrast-enhanced malignant or inflammatory tissue and the low signal lumen of the bowels. No side effects were noted.

[Preoperative spiral CT cholangiography with 3-dimensional surface reconstruction: the anatomical imaging potentials, limits and application strategies]. / Präoperative Spiral-CT-Cholangiographie mit dreidimensionaler Oberflächenrekonstruktion: anatomische Darstellungsmöglichkeiten, Grenzen und Einsatzstrategien.

PURPOSE: Evaluation of CT cholangiography compared to i.v. cholangiography concerning its diagnostic value before laparoscopic cholecystectomy and optimisation of CT cholangiography. METHOD: I.v. and CT cholangiographies of 54 patients were retrospectively evaluated by two radiologists. The time interval between contrast infusion and CT was correlated with the assessment of CT cholangiographies to detect the optimal timing for CT scanning. RESULTS: CT cholangiography was judged to be generally better than i.v. cholangiography. The optimal time interval for CT scanning is between 30 min and 60 min post contrast infusion. CONCLUSION: CT cholangiography should replace the conventional tomograms if i.v. cholangiography does not yield sufficient depiction of the biliary tree. It should be performed within 60 min post contrast infusion. Complete abolishment of i.v. cholangiography is not warranted. This is due to the fact that conventional cholangiography can sufficiently delineate the biliary tree and thereby reduce x-ray exposure and cost compared to initial performance of CT cholangiography.

[Imaging of the abdominal wall: combination of tissue-harmonic-imaging and extended field-of-view sonography]. / Ultraschall der Bauchdecke: Kombination von Tissue-Harmonic-Imaging und Panorama-Ultraschall.

PURPOSE: To evaluate the combined use of extended field-of-view sonography and tissue harmonic imaging (THI) for assessment of the abdominal wall. MATERIALS AND METHODS: In 32 patients (25 patients without and 7 patients with abdominal wall pathologies) extended field-of-view sonography of the abdominal wall was performed with and without THI using a 7.5 MHz ultrasound transducer. Images with a scan length of 60 cm were acquired above and below the arcuate line. The images were independently assessed by two observers regarding visibility of the anatomic structures and delineation of pathological changes using a 4-point grading scale. Furthermore, the influence of the extent of the subcutaneous fat on the image quality was assessed. For statistical analysis, kappa coefficients, Fisher"s exact test and a repeated measurement analysis of variance (ANOVA) were applied. RESULTS: In all patients, delineation of the abdominal wall was possible with diagnostic image quality. Abdominal wall pathologies were concurrently diagnosed for extended field-of-view sonography with and without utilization of THI. Image quality was rated better with THI when compared to extended field-of-view B-Mode sonography. In comparison to extended field-of-view B-Mode sonography, the agreement between both readers regarding image quality was markedly improved using extended field-of-view sonography in combination with THI. With increasing thickness of the subcutaneous fat layer, image quality was rated significantly better using THI than B-Mode ultrasound. CONCLUSION: Combined use of extended field-of-view sonography and THI improves image quality and documentation of ultrasound examinations. Especially in obese patients, the use of THI is advantageous. Therefore, abdominal wall ultrasound gains additional value in the preoperative planning.

[Panorama ultrasonography of the abdominal wall for delineation of the anatomy and diagnosis of pathological findings]. / Panorama-Ultraschall der Bauchwand zur Darstellung der Anatomie und pathologischer Befunde.

PURPOSE: To assess extended field-of-view sonography for delineation of the anatomic structures of the abdominal wall and for the diagnosis of hernia. MATERIAL AND METHODS: In 34 cases (24 probands, 10 patients with abdominal wall defects) extended field-of-view sonography of the abdominal wall was performed with a 7.5 MHz transducer. Dynamic alignment of real-time images allows for depiction of regions of up to 60 cm in a single extended field-of-view image. A standardized axial image was obtained above and below the arcuate line and at the level of the defect, respectively. All images were evaluated by two blinded readers regarding the visibility of the anatomic structures and the delineation and extent of pathological changes. RESULTS: The abdominal wall was delineated with extended field-of-view sonography in all patients with a good image quality. The linea alba, the rectus muscle and the three lateral abdominal muscles, the rectus sheath, the peritoneum, and the subcutaneous fatty tissue were visible. In the patients with abdominal wall defects, the hernial sac with its contents, the extension of the defect, and the surrounding structures were clearly delineated. CONCLUSION: Extended field-of-view sonography allows for easily surveyed and reproducible documentation of the ultrasound examination of the abdominal wall. It is especially useful for the preoperative planning in patients with abdominal wall defects.

[Radioimmunoscintigraphy using SPECT: methodology, problems and clinical experiences]. / Radioimmunszintigraphie mit SPECT: Methodik, Probleme und klinische Erfahrungen.

Radioimmunoscintigraphy (RIS) with 111In-and 131I-labelled monoclonal antibodies (MAbs) against CEA and/or CA 19-9 was performed in 83 patients with various gastrointestinal carcinomas. A total of 276 body regions could be examined. The results of planar scintigraphy and SPECT were compared intraindividually. Using 111In-labelled MAbs the sensitivity of RIS was significantly improved by SPECT (88.9 vs. 52.4% with planar scintigraphy, p less than 0.01). For 131I-labelled MAbs the effect was smaller (83.9 vs. 65.6% with planar scintigraphy, n.s.). This finding can be explained by different kinetics and biodistribution of the used MAb preparations. 111In-labelled MAbs with long whole-body retention and rapid blood clearance reveal ideal qualities for SPECT; on the other hand, the short whole-body retention of 131I-labelled MAbs leads to small count rates and therefore long counting times that make delayed SPECT unsuitable in clinical practice.

Radioimmunoscintigraphy with 111In labelled monoclonal antibody fragments (F(ab')2 BW 431/31) against CEA: radiolabelling, antibody kinetics and distribution, findings in tumour and non-tumour patients.

Forty seven patients with suspected malignant disease (mainly colorectal cancer) were studied with 111In labelled F(ab')2 fragments of an anti-CEA monoclonal antibody (BW 431/31). The kinetic data revealed a long whole body retention of the label (62% after 4 days) and a rapid blood clearance (77% within 24 h, 89% within 48 h) leading to an early positive tumour contrast 24 h p.i. and optimal scintigrams 48 h p.i. Diagnostic results were promising in local recurrences of colorectal cancer (8/10 positive = 80%) though false positive findings in patients with inflammatory bowel disease occurred probably due to cross-reaction with a human granulocyte antigen. Liver metastases and tumours neighbouring liver and spleen were often missed (10/27 = 37%) because of high nonspecific uptake in these organs. Thus BW 431/31 proved to be a suitable compound for radioimmunodetection, however, further improvements to optimize tumour affinity and specificity of the antibody are mandatory.

[Sigmoid diverticulitis. Emergency intervention in abscess, hemorrhage and stenosis]. / Sigmadivertikulitis. Notfallinterventionen bei Abszess, Blutung und Stenose.

Interventional techniques in treatment of complicated diverticulitis gain more and more importance. In particular abscesses and bleeding are treated successfully. In case of diverticular abscess (Hinchey classification stage I and II) percutaneous drainages are placed sonographically or CT guided. Interventional drainage offers the possibility of elective one-stage surgical treatment of diverticulitis with significant reduce of mortality and morbidity rates. Diverticular bleeding is usually diagnosed and treated endoscopically. Only if endoscopy is not able to manage bleeding, angiography or nuclear scan is demanded. In case of stenosis endoscopic treatment has not jet gained clinical relevance.

[Video thoracoscopic therapy of spontaneous pneumothorax. Technique and initial results]. / Videothoracoskopische Therapie des Spontanpneumothorax Technik und erste Ergebnisse.

The acceptance of operative therapy of spontaneous pneumothorax (SPT) has been tempered by the serious trauma of thoracotomy access. Development of videoequipment and miniaturized instruments allows now a thoracoscopic resection of bulla with minimal access. 25 patients with recurrent SPT (n = 15), primary resistant SPT (n = 5), and first SPT (n = 5) were treated from January 1991 thoracoscopically. Bullae resection was performed with an Roeder ligature or an Endo-GIA. Pleurodeses was induced by mechanical irritation or coagulation of the upper thoracic aperture with the argon beamer. Postoperative lung reinflation was rapid and without patchy collapse. The analgetic drug demand was dramatically reduced and patients were mobilised on the 1st postoperative day. Patients were discharged on the 4th postoperative day. Major complication were one hematothorax and one recurrence of SPT. The advantages of the thoracoscopic surgical treatment are rapid full expansion of the lung, decreased postoperative pain, short postoperative hospital stay and early return to normal activity.

[Todani type I choledochal cyst--diagnosis and surgical therapy]. / Die Choledochuscyste Typ I nach Todani--Diagnostik und chirurgische Therapie.

Ultrasound, ERC and computed tomography are the main preoperative diagnostic procedures of common bile duct cysts. In individual cases the definitive diagnosis can be confirmed only intraoperatively. The high rate of complications and the risk of carcinoma requires a radical surgical treatment.

[Splenic cyst. Diagnosis, indications and choice of procedure]. / Die Milzcyste. Diagnostik, Indikation, Verfahrenswahl.

Based on two cases of splenic cysts diagnosis, indication, and selection of surgical methods are discussed. Ultrasound and computerized axial tomography prove to be the most important diagnostic methods. The indication to operate on cysts with a diameter exceeding 2 cm follows from possible complications. Because of the immunological importance of the spleen and the technical means of today a splenic resection should always be considered.

[Importance of sonography in diagnosis of ileus. A retrospective study of 459 patients]. / Die Bedeutung der Sonographie in der Ileusdiagnostik. Eine retrospektive Studie an 459 Patienten.

In a retrospective trial we investigated the significance of ultrasound in the diagnosis of intestinal obstruction in 459 patients. The overall sensitivity was 93.7%. In paralysis the correct diagnosis was obtained in 98% of all. Mechanical obstruction was identified in 91%. In cases of incomplete mechanical obstruction sensitivity was 89%. The corresponding value for complete obstruction was 95%. In all patients with negative findings on abdominal x-ray (10%) the correct diagnosis was established by ultrasound. Only in 71% of cases ultrasound was successful differentiating small bowel from large bowel obstruction. The underlying cause of ileus was yielded by ultrasound in 45% of the cases. On the basis of our experience ultrasound is proven to be of significant importance in the diagnosis and differentiation of ileus.
