Abstract
There is increasing evidence worldwide that human papillomavirus is a major risk factor for head and neck cancer. Only few studies on this association have been performed in Germany to date. For the purposes of the present study, tumor specimens from 223 patients with squamous cell cancer of the oral cavity, oropharynx, hypopharynx and larynx were analyzed for HPV DNA and p16INK4a expression. The prevalence of HPV genotype 16 (HPV16) DNA in the study population was 17.5%. Further high-risk HPV types were not detected. All HPV16-positive tumors showed intense p16INK4a expression. HPV16 prevalence was highest in tonsillar carcinoma (37.5%) and lowest in laryngeal cancer (2.8%). We observed a significantly higher incidence of cervical lymph node metastases in patients with HPV16-positive tonsillar carcinoma in comparison to HPV-negative tumors (p < 0.016). Tobacco and/or alcohol consumption was significantly lower in patients with HPV-positive tumors (p < 0.0001).

Abstract
Zusammenfassung
Gegenstand und Ziel: Es wurde untersucht, ob der Einsatz des Biozidprodukts T-Hexx Dragonhyde HBC (Fa. Hydromer, Branchburg, NJ, USA) die Prävalenz der Dermatitis digitalis (DD) beeinflusst. Material und Methoden: In einem Milchviehbetrieb (110 melkende Kühe) wurden 48 lahmheitsfreie Tiere randomisiert Versuchs- und Kontrollgruppe zugeteilt. Die mit 70–80% hohe Prävalenz der DD wurde 2 Monate lang vier Mal im Abstand von je 16–21 Tagen erfasst. Ein Punkteschema diente zur Dokumentation des Grades der DD-Läsionen an den Hinterklauen. Die Kühe der Versuchsgruppe wurden zweimal wöchentlich für zwei Melkzeiten nach Vorreinigung der Klauen mit Wasser durch ein Klauenbad mit T-Hexx-Dragonhyde geleitet, bei den Kontrolltieren erfolgte nur eine Klauenreinigung. Die Spritzer der Biozidlösung an Tieren und Umgebung wurden fotografisch dokumentiert und beurteilt. Wasser- und Biozidbad wurden nach Nutzung durch steigende Tierzahlen bakteriologisch untersucht. Ergebnisse: Statistisch signifikante Unterschiede der Prävalenzen der DD zwischen und innerhalb der beiden Gruppen waren nicht festzustellen. Die Punktebewertung der Läsionen differierte zwischen beiden Gruppen nicht. Im Wasserbad nahm mit steigender Zahl der Durchgänge die Zahl der koloniebildenden Einheiten (KBE) pro Milliliter sowie die der Enterobacteriaceae deutlich zu. Im T-Hexx-Dragonhyde-Bad ließen sich zu keinem Zeitpunkt KBE oder Enterobacteriaceae bestimmen. Die auffälligen Spritzer der Lösung waren bis in Höhe des Euters sichtbar. Schlussfolgerung und klinische Relevanz: Ein Einfluss des Biozidprodukts bei 4%- und 2%iger Badkonzentrationen auf die Prävalenz der DD konnte nicht nachgewiesen werden. Die hygienische Wirkung der Lösung war nicht gleichbedeutend mit einer erfolgreichen Keimreduktion an der Klaue. Eine mögliche Prävention der DD durch veterinärhygienische Maßnahmen könnte zukünftig bei geringerer Prävalenz und größerem Stichprobenumfang überprüft werden. Bei Anwendung von Klauenbädern besteht grundsätzlich die Gefahr einer Kontamination der Milch bzw. einer Mastitis durch Spritzer der Lösung.

Abstract
OBJECTIVE It was investigated whether usage of the biocidal product T-Hexx Dragonhyde (Hydromer, Branchburg, NJ, USA) could influence the prevalence of digital dermatitis (DD). MATERIAL AND METHODS On a dairy farm (110 milking cows) 48 dairy cows without lameness were selected randomly for a test group or a control (negative) group, respectively. A high prevalence of DD (70-80%) was documented over a period of 2 months, during which four examinations were made, with an interval of 16-21 days between each examination. The respective grade of the DD-lesion on the hind hoofs was documented according to a scoring scheme. After precleaning the claws with water, the test group passed through a hoof bath containing T-Hexx Dragonhyde on 2 days per week at two milking times on each day, whereas the claws of control animals were cleaned using only a water bath. Splashes contaminating the animals and the environment were documented photographically and evaluated. Bacteriological examinations of the water bath and the T-Hexx-bath were performed after increasing numbers of animals had passed through the baths. RESULTS Between and within groups no statistically significant differences in the prevalence of DD were found. DD-lesion scoring did not show any difference between the groups. With increasing numbers of animals having passed through the water bath, there was a significant increase in colony-forming units per millilitre and of enterobacteriaceae. In the T-Hexx Dragonhyde footbath, bacterial contamination remained below the detection limit at all times. The coloured splashes of the footbath were visible up to the level of the udder and teats. CONCLUSION AND CLINICAL RELEVANCE The prevalence of DD was not influenced by the 2% or 4% concentration of the biocidal product in the footbath. Thus the microbiocidal effect of the solution did not lead to an efficient reduction in bacteria on the hoof. To demonstrate a potential preventive effect on DD, future studies would require herds with lower prevalence and a higher sample size. However, when applying footbaths there is the general risk of milk contamination or causing mastitis.

Abstract
BACKGROUND AND OBJECTIVE While there are evermore therapeutic options, a continuous rise in the prevalence of type 2 diabetes mellitus has been demonstrated in epidemiological studies and is leading to an increasing financial burden on health care systems. It has been shown in a number of studies that health-related lifestyle may be influenced by a telephone intervention program. PATIENTS AND METHODS The effect of a telephone intervention on physical activity and other important cardiovascular risk factors was investigated over a period of three months in patients with type 2 diabetes. Those in the intervention group (n=22) were phoned once weekly and only matters concerning their physical activity were discussed. The patients in a matching control group (n=20) were not phoned. RESULTS Physical activity increased in the intervention group with a significant difference when compared to the control group at the end of the three months' intervention. At the end of the intervention weight, body mass index, waist circumference, systolic blood pressure, triglycerides and fasting blood sugar where either significantly different between the intervention and control groups (absolute values) or showed a significantly greater decrease in the intervention group. In addition there was a tendency (not statistically significant) towards an improvement in the intervention group regarding other risk factors (body fat, diastolic blood pressure, total cholesterol, LDL, HDL, HbA1c). CONCLUSIONS These results demonstrate that a telephone intervention can increase physical activity and reduce cardiovascular risk factors. As a result it may reduce health care-related costs.

Abstract
Malignant melanomas (MMs) of the parotid gland are relatively uncommon. They occur almost invariably as metastases from a primary tumour located in the region of the scalp or the mucous membranes of the nose, paranasal sinuses, or throat. Primary MMs arising in the parotid gland are extremely rare. It is assumed that they originate in the glandular tissue or in intraglandular lymph nodes. We present a case report and review of the literature on the diagnosis, treatment, and prognosis of intraparotid malignant melanoma. Diagnosis is based primarily on B-scan ultrasonography and fine-needle aspiration cytology. Patients with a cytological diagnosis of MM are further evaluated by magnetic resonance imaging and positron emission tomography and receive a thorough ear-nose-throat and dermatological examination. The treatment of choice is total parotidectomy and selective neck dissection. The effectiveness of adjuvant treatments such as radiotherapy, chemotherapy, or immunotherapy remains controversial. Patients with primary MMs of the parotid gland appear to have a better prognosis than those with parotid metastases from melanomas of the skin or mucous membranes.

Abstract
BACKGROUND Prevalence data for colorectal neoplastic lesions obtained from screening colonoscopies have recently been reported for a U. S. American and a Polish average-risk population. However, prevalence data for a German average-risk population have not been published. METHODS From 1998 until 2003 a screening colonoscopy was offered to all male participants of a health assessment program. In a total of 618 volunteers with an average risk for colorectal cancer, polypoid lesions were identified and removed using high-resolution video colonoscopes. The histological features of the lesions were categorised according to those of the most advanced one. An advanced lesion was defined as an adenoma of at least 1 cm in diameter, a polyp with villous histological features or high-grade intraepithelial neoplasms or a cancer. Data were analysed in two groups: age 40 - 49 years (group A) and age 50 - 59 years (group B). RESULTS In group A (age 40 - 49 years, n = 285), 133 subjects (47 %) had polypoid lesions. Histological findings revealed that 57 subjects (20 %) had non-neoplastic and 76 subjects (27 %) had neoplastic lesions. In nine cases (3.2 %) polyps were classified as advanced lesions with a maximal diameter of 35 mm. In group B (age 50 - 59, n = 333), 183 subjects (55 %) had polypoid lesions. Histological findings revealed that 64 subjects (19 %) had non-neoplastic and 119 subjects (36 %) had neoplastic lesions. Among those, 34 (10.2 %) had advanced lesions with a maximal diameter of 55 mm. In neither group was an invasive cancer detected. The difference in the prevalence of neoplastic lesions between the two age groups was statistically significant (chi (2) = 5.85). An exceptionally high rate of 27 % neoplastic lesions was detected in subjects at 40 to 49 years of age. The rate of detected lesions in the group of older subjects was 36 %. CONCLUSION By using high-resolution endoscopes we found an unexpectedly large number of neoplastic lesions in the colon even in a relatively young average-risk population. The question whether screening colonoscopy should therefore not only aim at detecting early colorectal cancer but also at identifying and removing precursor adenomas at younger ages clearly deserves further attention.

Abstract
DNA ploidy studies on salivary gland tumours have shown that the proportion of aneuploid cases, although confined to the malignant entities, is considerably lower than for other solid malignancies. To analyse whether the S-phase fraction (SPF) may contribute to discrimination of diploid malignant from benign tumours, DNA flow cytometric data from 45 different malignant salivary gland tumours was compared with that of 121 pleomorphic adenomas. All benign tumours were diploid. Twelve malignant tumours contained aneuploid cell populations. The SPF values for diploid malignancies ranged between 0.9% and 11.0% (mean 3.9%), and between 0.5% and 7.9% (mean 2.7%) for pleomorphic adenomas. A 4% cut-off value gained statistical significance for discriminating diploid malignant tumours from pleomorphic adenomas (P<0.01). The sensitivity for SPF>4% was 46% and the positive predictive value was 40%. A sensitivity of 60% and a positive predictive value of 54% was achieved by combining aneuploidy and SPF>4%. These results show that DNA flow cytometry may contribute to diagnostic assessment in salivary gland tumours.

Abstract
Leiomyosarcoma is usually found in the female genital tract, retroperitoneum, the wall of the gastrointestinal tract and subcutaneous tissues. An appearance of this malignant tumor in the larynx is extremely rare and may be difficult to diagnose. Because of its rarity, little information exists on management and prognosis. We report on a 64-year old male with a supraglottic leiomyosarcoma who was treated with supraglottic laryngectomy and postoperative radiotherapy. After 19 months the patient was well and free of disease. The most commonly used diagnostic and therapeutic procedures are analysed in a review of the 46 published cases of laryngeal leiomyosarcoma.

Abstract
Parotid hemangiomas are rare in adults. Whereas both capillary and cavernous hemangiomas are seen in children, only cavernous hemangiomas have thus far been reported in adults. Clinically, cavernous hemangiomas usually present as slowly growing, soft or firm, movable, painless parotid masses. Severe pain and swelling can occur, however, depending on the size of the hemangioma or in particular in the presence of acute hemorrhage or thrombosis. CT and MRI are the diagnostic tools of choice. Prior to surgery, magnetic resonance angiography or intra-arterial digital subtraction angiography should be performed to investigate the vascular supply of the tumor. Surgical excision is the treatment of choice for small lesions. Large cavernous hemangiomas usually require superficial or total parotidectomy. Especially in the case of extended lesions, the facial nerve may be difficult to identify and should be monitored intraoperatively.

Abstract
The purpose of this study was to compare the efficacy and cost of the limited-dose Daclizumab regimen to that of the standard-dose Basiliximab regimen. Two antibody induction regimens were compared in patients aged 18 years and older who received renal transplants from January 2002 to September 2003 and completed interleukin (IL)-2R antibody induction with standard-dose Basiliximab (20 mg x 2 doses) or limited-dose Daclizumab (1 mg/kg x 2 doses). The primary outcome measure was the incidence of acute rejection. Secondary outcomes included cost, changes in serum creatinine level, and delayed graft function. Of the 46 patients randomized, 42 patients completed the 6-month follow-up. Mean serum creatinine level at time of discharge was originally higher in the limited-dose Daclizumab group than the standard-dose Basiliximab group (1.89 vs 1.57, respectively). By 1, 3, and 6 months, mean serum creatinine values were similar between both groups, with a trend toward lower mean serum creatinine values in the limited-dose Daclizumab group. The incidence of acute rejection was also similar between the groups (6% vs 7%). The average cost difference between the 2 regimens was approximately $715. This study suggests that a limited-dose Daclizumab regimen may be an efficacious and less costly alternative to the standard-dose Basiliximab regimen for antibody induction therapy following renal transplantation.

Abstract
Salivary duct carcinoma is a highly malignant tumor. Pain, facial nerve palsy, perineural and lymphatic invasion are common findings, as well as an extensive cervical lymph node involvement and distant metastasis. However, occasionally, as in the case presented, the clinical features of this tumor may resemble obstructive sialadenitis and thus cause a delay in appropriate treatment. Although salivary duct carcinoma exhibits an unpredictable clinical course and a poor overall prognosis, total parotidectomy with neck dissection and adjunctive radiation therapy appear to be appropriate for local and regional control of this aggressive neoplasm.

Abstract
BACKGROUND Of various endoscopic hernia repair procedures, TAPP and TEP have been selected for routine use. METHODS Results from Medline research were analysed. RESULTS There is a similar risk for postoperative morbidity for both techniques. The recurrence rate in large single-centre series is between 0% and 3.4%. There were numerous indications for both procedures, whereby a transperitoneal TAPP can also be applied in cases of previous preperitoneal operations. CONCLUSION Randomised trials comparing both methods of hernia repair are lacking. Seven non-randomised studies showed no differences in recurrence rate and morbidity. In general the learning curve for is shorter in favour of TAPP repair.

Abstract
Malignant tumors of the spermatic cord are rare with primary neoplasms being mostly sarcomas. Adenocarcinomas of the spermatic cord are found extremely seldom and are predominantly metastases of extragonadal tumors. We present an asymptomatic 47-year-old patient who was referred to our clinic after a vasectomy had been performed and the histological examination had surprisingly shown adenocarcinoma of the left spermatic cord. Extensive laboratory analysis and diagnostic imaging did not demonstrate any testicular, spermatic cord, or extragonadal tumor. To exclude a mix-up of specimens, we performed DNA analysis. Microsatellite PCR clearly demonstrated the different origins of the tumor and the vasectomy specimen. Specimen mix-up or contamination may happen in any phase of surgical or pathological processing. In any case of clinical uncertainty concerning the identity of a tissue specimen, this possibility has to be taken into consideration. Microsatellite PCR can clearly identify the origin of tissue samples even on embedded material.

Abstract
BACKGROUND The aim of this study was to examine the advantages and risks of the Automated Endoscopic System for Optical Positioning (AESOP) 3000 robot system during uncomplicated laparoscopic cholecystectomies or laparoscopic hernioplasty. METHODS In a randomized study, we examined two groups of 120 patients each with the diagnosis cholecystolithiasis respectively the unilateral inguinal hernia. We worked with the AESOP 3000, a robotic arm system that is voice-controlled by the surgeon. The subjective and objective comfort of the surgeon as well as the course and length of the operation were measured. RESULTS The robot-assisted operations required significantly longer preparation and operation times. With regard to the necessary commands and manual camera corrections, the assistant group was favored. The same was true for the subjective evaluation of the surgical course by the surgeon. CONCLUSIONS Our study showed that the use of AESOP during laparoscopic cholecystectomy and hernioplasty is possible in 94% of all cases. The surgeon must accept a definite loss of comfort as well as a certain loss of time against the advantage of saving on personnel.
