    Abstract: BACKGROUND: The incidence of skin cancer continues to increase. However, little is known about the dermatosurgical characteristics of the patients. PATIENTS AND METHODS: In this single center, retrospective study, dermatosurgical reports of all patients treated because of basal cell carcinomas (BCC), squamous cell carcinomas (SCC), and malignant melanoma (MM) between 2004 and 2013 were analyzed. RESULTS: During the observed period, the number of operated BCC rose by a factor of 1.86 and the number of MM by a factor of 2.3. In comparison to BCC/MM, there was a disproportionately high increase of SCC by a factor of 4.02. The average age was 71.5 +/- 13.4 years (minimum: 14 years; maximum: 104 years), whereupon a significant increase of male age and a significant decrease of female age occurred. Almost 70% of all tumors were located in the head and neck area. The nose was most commonly treated. CONCLUSIONS: During the last 10 years, the cohort of dermatosurgical patients changed in the tumor center. This should be verified in multicenter studies.

    Description: Chronisch-rezidivierende infektiöse Parotitiden im Kindesalter sind allseits bekannt. Als Ursache wird eine Störung der Sekretbildung , aber auch angeborenen Strikturen des Gangsystems dikutiert. Zunehmend häufig sind atypische Mycobakterien - Infektionen. Fremdkörper als Ursache einer Parotitis wurden in der Literatur nur in Einzefällen beschrieben.Wir berichten über ein einjährigen Kind mit undulierendem Fieber seit mehreren Wochen, einer Schwellung links präaurikulär sowie eitriger Otorrhoe links. Weiterhin bestanden Meningismuszeichen und Lymphknotenschwellungen links cervical.Nach Ausschluß einer Mastoiditis, lokaler Behandlung des linken Ohres mit chinolonhaltigen Ohrentropfen, sowie zusätzlich intravenöser Antibiose kam es nach drei Tagen zu einer Entfieberung des Kindes, wobei eine umschriebene pustulöse Effloreszenz links präauriculär bestehen blieb. Aufgrund der Sekretion aus dem linken Gehörgang bei blandem Trommelfell mußte an eine kongenitale Fehlbildung des 1. Kiemenbogenganges Typ II nach Work gedacht werden. Differentialdiagnostisch mußte auch eine eitrige einschmelzende Lymphadenitis und eine atypische Mykobakteriose diskutiert werden. Wir entschlossen uns zu einer operativen Exploration zur Histologiegewinnung und eventuel Resektion der vermeintlichen Gehörgangsduplikatur. Dabei fanden wir eine über den Boden des Gehörganges vollständig in die Glandula parotis eingedrungene Daunenfeder als Ursache der Entzündung.Nach erfolgter Entfernung kam es zu einer problemlosen Abheilung, so daß wir das Kind zeitnah entlassen konnten.

    Notes: Abstract Recurrence-free survival (RFS) in patients with small hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT) was analyzed. From 1988 until 1996, 725 OLTs were performed in 669 patients. In 52 adults, HCC was confirmed histologically. OLT was limited to patients with small (〈 5 cm) HCC with a maximum number of three nodules. Actuarial survival for these 52 patients at 1 and 5 years is 88 % and 71 %. RFS was defined as time until death without recurrence, time until follow up with a diagnosis of recurrence, or, in patients without recurrence, time of last follow up. Overall, the 5-year RFS was 60 %. Five-year RFS was less for bilobar compared to unilobar tumors (36 % vs 70 %), less for stage IVa tumors (UICC) compared to stage I–III tumors (17 % vs 71 %), and less for multiple compared to solitary tumors (54 % vs 67 %). In conclusion, potential cure may be achieved in more than 50 % of all transplanted patients.

    Notes: Abstract The optimal immunosuppressive regimen in patients transplanted for hepatitis C (HCV) is still under discussion. High immunosuppression may promote viral replication and recurrent graft hepatitis. But acute and chronic rejection frequently seen in conjunction with HCV recurrence may require some rescue therapy. One hundred and thirty-seven patients transplanted for HCV cirrhosis, who were HCV-RNA positive prior to transplantation, were analyzed. Seventy-nine patients received CSA-based immunosuppression and 58 patients FK506-based immunosuppression. One-month patient survival was 100 % in both groups. Three month and 1-year survival rates and the cumulative 1–5-year patient survival was similar in CsA-treated [67/79 (84.8 %)] and FK506-treated patients [50/58 (86.2 %)]. Retransplantations for HCV recurrence were performed in 5.1 % of CsA-treated patients and 6.9 % of FK506-treated patients; it was successful in 50 % and 75 % of patients, respectively. Conversion from CsA to FK506 and vice versa was high with 25 out of 79 patients (31.6 %) converting in the CsA group and 8 out of 58 patients (13.8 %) converting in the FK506 group. Conversion to FK506 was performed due to acute and chronic rejection and to CsA because of toxicity and HCV recurrence. In both groups, 25 % of converted patients died. Five patients of the CsA group and 9 of the FK506 group received OKT3; more than one-third of each group died. Five patients in the CsA group and 6 in the FK506 group received mycophenolate mofetil (MMF) for HCV recurrence or acute and chronic rejection in conjunction with HCV recurrence. All patients of this critical group are alive with good graft function. In conclusion, survival rates of HCV patients were similar to those seen for other indications. Conversion from CsA to FK506 and vice versa was high and reflects a critical group concerning patient survival. OKT3 treatment should be avoided. A promising therapeutic option for critical patients experiencing acute or chronic rejection in conjunction with HCV recurrence may be treatment with MMF.

    Notes: Abstract We have reviewed our experience with conversion to tacrolimus after 435 liver transplantations. Tacrolimus was administered as a rescue agent in 33 patients until October 1993. Indications for rescue therapy were: cholestatic forms of severe, steroid-resistant cellular rejection (n=8), OKT3-resistant cellular rejections (n=6), cellular rejections in patients suffering from cyclosporin malabsorption (n=4), late onset cellular rejections (n=4), early chronic rejections (n=3), and chronic vascular or ductopenic rejections (n=8). Response was evident in 29 of the 33 patients (88%), whereas 4 patients (12%) were nonresponsive. Patient and graft survival were 76% and 70%, respecitively. Graft loss with or without patient death occurred in three of eight patients suffering from severe, steroid-resistant cellular rejection, in two of six patients with OKT3-resistant cellular rejections, and in five of eight patients undergoing chronic rejection. In severe steroid-resistant cellular rejection, successful tacrolimus rescue therapy corresponded to a significantly lower total serum bilirubin than unsuccessful therapy (12.0±5.6 mg% vs 29.7±5.9 mg%, P(0.05). We conclude that tacrolimus rescue therapy is a safe and efficient alternative for high-risk cases that do not respond to conservative treatment. In severe, steroid-resistant cellular rejection and in chronic ductopenic rejection, conversion to tacrolimus is beneficial only in a limited number of cases. A predictive parameter, which total serum bilirubin may prove to be in severe, steroid-resistant cellular rejection, is needed to select those cases that might benefit more from retransplantation than from conversion to tacrolimus.

    Notes: Abstract Hereditary hemorrhagic teleangiectasia, or M. Osler (Osler-Weber-Rendu disease), is an autosomal dominant, systemic fibrovascular dysplasia. This may lead to increased liver blood flow from arteriovenous fistulas. A 45-year-old woman with a known M. Osler was admitted for liver transplantation. On admission, exertional dyspnea was the predominant symptom. Radiological investigations revealed multiple intrahepatic arteriovenous fistulas and consecutive high-output heart failure. Laboratory findings revealed remarkably elevated bilirubin and alkaline phosphatase. To alleviate the high-output cardiac failure, the hepatic artery was ligated. Fourteen months later, the patient presented again with increased levels of bilirubin and recurrent bleeding episodes from esophageal varices grade IV. The patient underwent liver transplantation and post-transplant recovery was excellent. A hyperdynamic circulatory state due to a hepatic M. Osler has been treated in several cases by ligation or embolization of the hepatic artery. This procedure, however, is recommended only for patients with normal liver function and carries a considerable risk of bile duct necrosis.

    Description / Table of Contents: Zusammenfassung. Wir berichten exemplarisch über drei Patienten, die im Zeitraum von Februar 1991 bis Oktober 1994 in unserer Klinik wegen intraabdomineller Schwannome operiert wurden. Im Fall 1 wurde ein benignes Schwannom des Magens durch Billroth-II-Resektion behandelt, Leitsymptom war eine gastrointestinale Blutung. In Fall 2 wurde ein malignes Schwannom des Duodenums mit Lebermetastase durch weite En-bloc-Tumorresektion mit retroperitonealer Lymphadenektomie und anatomischer Rechtsresektion der Leber behandelt. Eine nach 7 Monaten aufgetretene metachrone Lebermetastase wurde durch intraparenchymatöse Lasercoagulation kontrolliert, ein nach 19 Monaten aufgetretenes Lokalrezidiv erforderte eine weitere Tumorresektion. Primäres Leitsymptom war eine palpable Tumormasse. In Fall 3 wurde ein malignes Schwannom der Bauchwand auswärts in Fragmenten reseziert. Trotz postoperativer Radiatio kam es nach 6 Monaten zum Lokalrezidiv mit Leberinfiltration, welches en bloc reseziert wurde. Zu diesem Zeitpunkt bestand bereits eine beginnende Peritonealsarkomatose. Unter postoperativer Chemotherapie kam es zum raschen Tumorprogreß. Der Patient verstarb 18 Monate nach Erstoperation. Anhand der dargestellten Fälle werden Symptomatik, differentialdiagnostische Probleme und operatives Vorgehen bei benignen und malignen Schwannomen des Bauchraums erörtert.
    Notes: Summary. We report three patients who were operated on because of an intraabdominal schwannoma between February 1991 and October 1994 in our department. In the first case, a benign gastric schwannoma was treated by a distal gastric resection (Billroth II); the main symptom was gastric bleeding. In the second case, a malignant duodenal schwannoma with liver metastasis was treated by wide en-bloc resection of the tumor including retroperitoneal lymphadenectomy and an anatomical resection of the right lobe of the liver. A metachronous metastasis of the liver, appearing 7 months postoperatively, was treated by intraparenchymatous laser coagulation; a local recurrence, appearing 19 months postoperatively, led to another tumor resection. The main symptom was a palpable intraabdominal mass in this case. In the third case, a malignant schwannoma of the abdominal wall was resected in fragments in another clinic. Six months later a local recurrence with infiltration of the liver appeared in spite of postoperative radiation and was resected en bloc. Early peritoneal sarcomatosis was apparent at that time. Postoperative chemotherapy did not prevent quick progression of the tumor. The patient died 18 months after the first operation. The clinical presentation, differential diagnosis and operative strategy for benign and malignant intraabdominal schwannomas are discussed.
