No full textIn unserer retrospektiven Auswertung von 1.239 Zwillingsgeburten nach
maternalen Charakteristika an einem perinatalen Zentrum Level 1 in der Charité
Universitätsmedizin Berlin, am Campus Virchow-Klinikum konnte gezeigt werden,
dass in dem Untersuchungszeitraum die Anzahl der Zwillingsgeburten, sowohl die
der spontan entstandenen als auch die nach Sterilitätsbehandlung zugenommen
haben. Jedoch wurde eine deutlich vermehrte Zunahme bei den
sterilitätsbehandelten Müttern festgestellt. Auch konnte gezeigt werden, dass
das maternale Durchschnittsalter bei den sterilitätsbehandelten Müttern
signifikant höher und die mittlere SSW bei Geburt signifikant niedriger lag.
Zusätzlich konnte eine stetige Zunahme des maternalen Durchschnittsalters im
beobachteten Zeitraum analysiert werden, mit einem stärkeren Anstieg des
maternalen Alters von 3,2 Jahren bei den Zwillingsschwangeren mit
Sterilitätsbehandlung. Im Vergleich nahm das maternale Durchschnittsalter der
Zwillingsmütter mit spontan entstandenen Zwillingen nur um 1,7 Jahre zu.
Ebenfalls konnte ermittelt werden, dass der Anteil an Zwillingsschwangeren
nach Sterilitätsbehandlung, die entbunden wurden, mit 35 % über ein Drittel
aller Zwillingsschwangerschaften in dem hier untersuchten Kollektiv ausmachte
und diese Tendenz steigend ist. Während des gesamten Untersuchungszeitraumes
kam es zu keinem maternalen Sterbefall im Gesamtkollektiv. In unserer Arbeit
konnten zwischen den beiden Gruppen „Sterilitätsbehandlung“ und „spontan“ in
folgenden Kategorien keine signifikanten Unterschiede festgestellt werden: BMI
vor Konzeption, Gewichtsdifferenz Beginn/Ende der Schwangerschaft,
Gestationsdiabetes, SIH, Präeklampsie, HELLP-Syndrom, primäre Sektio, eilige
Sektio, Notsektio, 1. Kind spontan/ 2. Kind sekundäre Sektio und Dammriss.
Allerdings konnte gezeigt werden, dass es bei den sterilitätsbehandelten
Zwillingsmüttern in folgenden Kategorien zu einem signifikant höheren
Vorkommen gekommen ist: Anteil ≥ 35-Jährigen, maternale Größe,
Chorionverhältnisse DC-DA, präpartale Blutungen, vorzeitige Zervixreifung,
Fruchtblasenprolaps, vorzeitiger Blasensprung, DC: Frühgeburtlichkeit < 37
vollendete SSW, DC: Frühgeburtlichkeit < 32 vollendete SSW, Sektiorate
insgesamt, sekundäre Sektio, postpartale Blutungen, Anämie im Wochenbett und
Hypothyreose. Zusammenfassend konnten wir in unserer Arbeit feststellen, dass
es bei Müttern, die durch eine Sterilitätsbehandlung mit Zwillingen schwanger
wurden, zu signifikant höheren prä- und perinatalen maternalen Komplikationen
gekommen ist als bei Müttern mit spontan entstandenen Zwillingen.Mothers of twins after FT appear to be significantly older, have higher
prematurity- and C-section-rates as well as higher obstetrical morbidity
compared to those spontaneously conceived

Seltene Erkrankungen mit klinischer Relevanz – das Silver-Russell-Syndrom
No full textThe Silver-Russell syndrome (SRS) is a rare imprinting disease associated with pre- and postnatal growth retardation, craniofacial features, and asymmetry. Genitourinary abnormalities are seen in up to 20% of affected individuals. Apart from structural renal anomalies, cryptorchidism and hypospadias occur frequently in boys, while girls often have anomalies similar to those in Mayer-Rokitansky-Kuster-Hauser syndrome with congenital hypoplasia or aplasia of the uterus and upper part of the vagina. Frequently hypospadias repair and orchiopexy are difficult because of lack of buccal mucosa due to facial dysmorphism and intraabdominal position of the testicles, respectively. Anesthetic problems with SRS children can be profound and mostly concern a difficult airway due to facial dysmorphism. Especially the young, very thin SRS patients are prone to hypoglycemia and hypothermia and require close perioperative monitoring. Children with SRS and their families face challenges from birth to adulthood. In case of urogenital abnormalities, they should receive multidisciplinary care by pediatric urologists/surgeons and pediatric anesthesiologists in a center of expertise in rare diseases
Late diagnosis of cryptorchidism
No full textCryptorchidism is a risk factor for testicular cancer and reduced fertility. Failure of critical maturation steps, with the persistence of gonocytes beyond 6 months, results in a decreased number of adult dark (A-dark) spermatogonia, which causes a deficiency of primary spermatocytes at 3 years of age. We evaluated the histological findings in boys older than 4 years who were diagnosed with a testis located in the inguinal channel. From September 2007 to September 2008, 15 boys (mean age 8 years) underwent orchidopexy with a biopsy taken from the undescended testis of one side. Sonograms were performed in all 15 boys. The incidences of spermatogonia, primary spermatocytes, and Leydig cells (semiquantitative) were estimated as well as the exclusion of intratubular carcinoma in situ cells (Department of Pathology, Central EM Lab, University Medical Center Regensburg, Germany). Orchidopexy was performed on the right side in eight boys, the left side in one, and both sides in six. Sonographically, no parenchymal echotexture abnormalities were found. A-dark spermatogonia could be detected in nine biopsies. The Leydig cell score was reduced in 11 boys. No carcinoma in situ cells were detected. Late diagnosis of undescended testis will have a poor prognosis for future fertility
Ergebnisse der laparoskopischen Orchidopexie beim nicht palpablen Hoden
No full textLaparoscopy is an established diagnostic procedure but is less frequently used as a therapeutic method for impalpable testes. To compare the results of the classic two-stage orchidopexy described by Fowler-Stephens with a testicular vessel-sparing single-stage approach in the management of intra-abdominal testes we retrospectively analyzed our data. From January 2005 to September 2010, 105 patients (mean age 32 months) underwent laparoscopy for impalpable testes. In cases of intra-abdominal testes, laparoscopic orchidopexy was performed either in a two-stage procedure including initial ligation of the testicular vessels or as a direct single-stage procedure without ligation of the vessels. The results of both approaches were evaluated postoperatively clinically and by ultrasonography. Among the 122 impalpable testes 63 were located intra-abdominally; single-stage orchidopexy was performed in 29 testes whereas a two-stage approach was conducted in 14 testes. Fourteen gonads had to be removed due to atrophy and in six cases no testis was found at all. In the other 59 cases inguinal exploration followed resulting in 22 orchidopexies, 34 removals and 3 blind-ending vessels. During a mean follow-up of 17 months none of the 29 testes treated by single-stage orchidopexy atrophied or reascended. By contrast, two cases of atrophy, one reascent and one subumbilical wound infection occurred after the two-stage procedure. Considering our excellent experiences with single-stage management, we conclude that the single-stage approach is a reliable, safe and efficacious treatment modality of intra-abdominal testes. However, the two-stage procedure including testicular vessel ligation should be restricted to high abdominal testes with very short vessels
Sonographie des Skrotalinhalts bei Säuglingen und Kleinkindern
No full textBesides physical examination, ultrasonography is the most valuable diagnostic tool to assess the scrotum and testes in the case of an acute scrotum or scrotal pathology. In infants and toddlers the examination can be challenging. Due to the limited patient compliance, the small testicular size (< 0.5 ml), and low blood flow velocity (< 3 cm/s), it can be difficult to achieve a proper flow curve when assessing blood flow. The examiner's skills are as important as adequate equipment (i. e., linear ultrasound probe, 12-14 MHz) and optimal program settings (Doppler scale < 3 cm/s, gate 1 mm). However, if there is doubt, surgical exploration is unavoidable
