    Notes: Abstract. In order to clarify abnormal findings at abdominal ultrasound (suspicion of late abscess subsequent to appendectomy) in a young male patient with known familial Mediterranean fever (FMF), a helical CT examination of the abdomen was performed. At CT, extensive serositis of the lower abdomen was detected. Findings at CT were verified 2 weeks later at laparoscopy.

    Notes: Abstract: Cutaneous aging is a complex biological phenomenon affecting the different constituents of the skin. To compare the effects of intrinsic and extrinsic aging processes, a total of 83 biopsies were collected from sun-exposed and protected skin of healthy volunteers representing decades from the 1st to the 9th (6–84 years of age). Routine histopathology coupled with computer-assisted image analysis was used to assess epidermal changes. Immunoperoxidase techniques with antibodies against type I and type III collagens and elastin were used to quantitatively evaluate changes in collagen and elastic fibers and their ultrastructure was examined by transmission electron microscopy. Epidermal thickness was found to be constant in different decades in both sun-exposed and protected skin; however, it was significantly greater in sun-exposed skin (P = 0.0001). In protected skin, type I and III collagen staining was altered only after the 8th decade, while in sun-exposed skin the relative staining intensity significantly decreased from 82.5% and 80.4% in the 1st decade to 53.2% and 44.1% in the 9th decade, respectively (P = 0.0004 and 0.0008). In facial skin the collagen fiber architecture appeared disorganized after the 4th decade. The staining intensity of elastin in protected skin significantly decreased from 49.2% in the 1st decade to 30.4% in the 9th decade (P = 0.05), whereas in sun-exposed skin the intensity gradually increased from 56.5% in the 1st decade to 75.2% in the 9th decade (P = 0.001). The accumulated elastin in facial skin was morphologically abnormal and appeared to occupy the areas of lost collagen. Collectively, the aging processes, whether intrinsic or extrinsic, have both quantitative and qualitative effects on collagen and elastic fibers in the skin.

    Description / Table of Contents: Zusammenfassung. Aus epidemiologischen Untersuchungen ist bekannt, daß bei ca. 50 % der Kinder mit einseitiger Leistenhernie auf der Gegenseite ebenfalls ein offener Processus vaginalis vorliegt. 10–25 % dieser Kinder entwickeln in der Folge eine kontralaterale Hernie. Seit 1996 wird in unserer Klinik bei Säuglingen und Kindern mit klinisch unilateraler Leistenhernie mittels intraoperativer Laparoskopie durch den eröffneten Bruchsack der kontralaterale innere Leistenring inspiziert. Vorgehen: Bisher wurden 112 Kinder untersucht (Alter: 6 Monate bis 7 Jahre; 78 Jungen, 34 Mädchen). Nach Freipräparation des Bruchsacks wurde dieser eröffnet und ein 5,5-mm-Trokar durch den inneren Leistenring eingebracht. Nach Anlage des Pneumoperitoneums erfolgte mit einer 5-mm-(30 °)-Optik zunächst die orientierende Laparoskopie, anschließend mit der 70 °-Optik die Inspektion des kontralateralen inneren Leistenrings. Ergaben sich Hinweise für einen breit offenen Processus vaginalis (Typ III nach Chin), wurde in gleicher Narkose diese Seite ebenfalls offen chirurgisch exploriert. Ergebnisse: Laparoskopisch fand sich bei 19 Patienten (17 %) ein nach oben genannten Kriterien pathologischer Befund (6 Mädchen, 13 Jungen). Diese wurden auf der Gegenseite operiert und die laparoskopische Diagnose in allen Fällen bestätigt. Verfahrensbedingte Komplikationen traten nicht auf. Die Eingriffe erfolgten im Rahmen der Eintageschirurgie. Die Operationsdauer erhöhte sich durch die intraoperative Laparoskopie um im Median 6 min (3–11 min). Deutlich häufiger fanden sich pathologische Befunde bei Patienten unter 2 Jahren (14 von 19 Patienten). Schlußfolgerungen: Das beschriebene Verfahren erlaubt ohne nennenswerten zusätzlichen Zeitbedarf, Patienten zu selektionieren, die von einer einzeitigen offenen Exploration der gegenseitigen Leistenregion profitieren. Somit können Zweitoperationen mit erneuter Narkose und Hospitalisierung vermieden werden. Zusätzlich erlaubt die intraoperative Laparoskopie die allgemeine Beurteilung der Abdominalorgane sowie Klärung spezieller Fragen wie, z. B. die Vitalität reponierter Darmschlingen.
    Notes: Summary. Background: Approximately 50 % of children with a clinical unilateral inguinal hernia display a patent processus vaginalis on the contralateral side; half of these children subsequently develop an inguinal hernia.The management of this problem is still controversial. The purpose of this study was to evaluate the usefulness of intraoperative laparoscopy in a no-puncture technique through the opened hernia sack. Method: In 112 children (age 6 months to 7 years ) with clinical unilateral hernia laparoscopy (5 mm laparoscope, 30 ° and 70 °). In cases of a wide-open contralateral internal inguinal ring (type III) open surgical exploration was performed. Results: Nineteen patients (17 %) fulfilled the laparoscopic criteria of a type III ring; the diagnose was confirmed during open contralateral exploration. Fourteen of these patients were younger than two years. The median time for laparoscopy was 6 min (3–11 min). No complications associated with the laparoscopy were observed. Conclusions: Intraoperative laparoscopy during unilateral hernia repair allows the identification of patients who profit from bilateral open surgery during the same operation with little additional operating time and so far with no resulting complications. Application of this method may avoid a second hospitalization and operation, as well as an unnecessary routine bilateral open exploration. As an additional source of information through excellent visualization of the abdominal cavity, this method proved helpful to examine incarcerated bowel after repositioning.
