Alveolar hydatid disease of the liver: Brief review and spectrum of adjacent organ invasion

The purpose of this study is to show the spectrum of adjacent organ invasion and to make a brief review of hepatic alveolar hydatid disease (AHD), using CT and MR imaging. We retrospectively reviewed CT and MR images of three patients with various adjacent organ invasions surgically and histologically proven to be AHD. Local invasion to right kidney and adrenal, right hemidiaphragm and lung were detected in one patient, right adrenal in another patient and gall bladder, duodenum, gastric wall and pancreas invasion in the other. AHD may rarely extend to the gall bladder, stomach, duodenum, pancreas, right adrenal and kidney, diaphragm, pleura and lung. The extension of the disease outside the liver is usually encountered in patients with large, peripherally located masses in the advanced stage of the disease.     

Ileus bei ausgedehnten intraabdominellen Verkalkungen nach Peritonitis

Zusammenfassung. Wir berichten über einen 48 j?hrigen Patienten. In Folge einer bakteriellen Peritonitis hatten sich ausgedehnte intraabdominelle Verkalkungen gebildet. Diese hatten einen Obstruktionsileus verursacht. Im Rahmen einer Revisionslaparotomie wurden die Kalkspangen entfernt. Zur Rezidivprophylaxe veranla?ten wir eine percutane Bestrahlung mit 15 Gy. Zus?tzlich erfolgte eine systemische Indometacin-Applikation. Eine Literaturrecherche ergab nur 2 vergleichbare F?lle.      

Deprivation of form vision suppresses diurnal cycling of retinal levels of leu-enkephalin

Deprivation of form vision by the fitting of translucent occluders suppressed the diurnal cycling of enkephalinergic amacrine cells (the ENSLI amacrine cells), in the chicken. Daily periods of normal vision or enforcing temporal contrast using strobe lighting appeared to restore normal functioning of the ENSLI cells. These results suggest that the ENSLI cells are involved in retinal circuits that assess the quality of the visual image and control eye growth.     

Laparoscopic mesh repair of incisional hernia: an alternative to the conventional open repair?

Background Tension-free incisional hernia repair using alloplastic material increasingly replaces conventional repair techniques. This change resulted in a decreased recurrence rate (50% vs. 10%, respectively). Recently, laparoscopic approaches for the intraperitoneal tension-free mesh application have been introduced. The decreased trauma at the incision site and the reduction in wound infections appear to be the main advantages. The aim of the present study was to evaluate the early and long-term complications as well as patients’ contentment. Methods Laparoscopic hernia repair with intraperitoneal polytetrafluroethylene (PTFE) mesh implantation was performed on 62 patients at the Klinikum Grosshadern between 2000 and 2005 (29 males, 33 females age 60.7). Intra- and postoperative complications were registered prospectively and retrospectively analyzed. In addition, 57 patients were evaluated for recurrence, postoperative pain and patient contentment (median follow-up 409 days). Results A low complication rate was observed in our patient collective. One trocar bleeding occurred. Three patients presented with wound hematoma. The recurrence rate was 8% (2/25). Sixty-two percent of the patients were free of complaints postoperatively. Eighty-five percent would once again choose the laparoscopic approach for incisional hernia repair. Conclusion The laparoscopic technique was associated with a low recurrence rate, a small rate of wound infections and high patient comfort. Thus, the laparoscopic approach for mesh implantation appears to be a safe and effective method for the treatment of incisional hernias. The efficiency for laparoscopic intraperitoneal mesh implantation, however, should be further evaluated within a prospectively randomized multicenter trial. M. Stickel and M. Rentsch contributed equally.
