Abstract
BACKGROUND Previous studies have suggested that sexuality following surgery for rectal cancer is better in women than in men and differs with type of surgery in terms of impact on Quality of Life. However, the findings were inconsistent. The aim of the presented study was to address these issues. METHODS 570 patients that had undergone surgery for rectal cancer in our department from 1992 to 1999 were included. After determination of survival status questionnaires on Quality of Life were sent to 370 patients one to two years post surgery. We analysed data from 215 patients of which 103 were female and 112 male. 248 patients died during the time observed. Statistical analysis was done with descriptive methods, Kaplan-Meier analysis (log rank test), T-test and analysis of variance using SPSS 11.0 for Windows. RESULTS Significant differences were seen in symptom scales between men and women. Women scored higher for distress through medical treatment and had higher values for insomnia, fatigue and constipation. Both sexes had impaired sexual life but men had significantly higher values and felt more distressed by the impairment of sexuality than women. For patients receiving abdominoperineal resection sexuality was most impaired. Anterior resection with pouch had a detrimental effect on diarrhoea and treatment strain. CONCLUSION The study showed that sexuality is influenced by gender and type of surgery and impacts Quality of Life after surgery for rectal cancer. Assessing quality of life with generic and specific instruments is helpful to determine differences between surgical procedures, age, gender, and adjuvant therapy where standard parameters such as survival have their limitations.

Abstract
Cell culture studies have shown that NSAID may influence osteogenic activities of osteoblast cultures. However, these studies did not consider long-term effects on differentiating cells. The influence of Voltaren with the non-steroidal agent diclofenac on proliferation and gene expression of the osteoblast-like cell line SaOS-2 was investigated 2, 9, and 16 days after incubation. Two days after 24 h of incubation, 50 microg/ml diclofenac reduced the proliferation and collagen type I expression while 9 and 16 days later no effect was found on either of the parameters. In contrast, 50 microg/ml NSAID has no effect on alkaline phosphatase expression 2 days after incubation while 9 and 16 days later expression had been reduced. Lower concentrations (1.56 and 0.19 microg/ml) had no effects on the studied parameters. BrdU and MTT test showed that 50 microg/ml diclofenac reduced proliferative and metabolic activity. Lower concentrations (< or =25 microg/ml) had a lower or no influence. The findings indicate that the NSAID impairment depends on cellular differentiation stage and is not confined to the time during or immediately after NSAID incubation. According to these results in vitro testing of drugs should be performed over a longer time period to detect possible long-term impacts.

Abstract
We report on our experience with six patients with malignant sarcoma of the heart and show that long-term survival is possible after radical resection. At presentation, the 6 patients (3 male, 3 female) were 45.8 +/- 20 years old. Three patients are alive without evidence of metastases since 29.6 +/- 36.8 months, three patients died after 38 +/- 50.2 months due to distant metastases. Precise preoperative localization of the tumor by means of imaging techniques is very important. In some cases, radical surgery requires an ex situ procedure (autotransplantation). If necessary, the right heart can be resected almost completely, and reconstructed in the form of a Fontan-type circulation. A heart transplantation, as suggested by others, is not justified from our point of view, since prognosis is not better and donor organs are too rare. The results of radical resection are promising, but new concepts for treatment--in particular chemotherapy concepts--for these mostly middle-aged or young patients are required.

Abstract
Doze cadelas mestiças, adultas, foram submetidas à ovário-histerectomia e posteriormente distribuídas em dois grupos de seis animais. Um dos grupos recebeu estrógenos naturais conjugados na dose de 0,01mg/kg, via oral, a cada 48 horas, durante 12 meses, e o outro serviu como controle. A cada 60 dias foram realizadas colheitas de sangue e obtidos os valores de colesterol total, triglicerídeos, HDL, LDL e VLDL. Houve elevação do colesterol total e do LDL nas fêmeas sem reposição de hormônio. No grupo que recebeu estrógenos houve elevação do HDL. A ovário-histerectomia influenciou significativamente o perfil lipoprotéico; a reposição com estrógenos foi capaz de preservar esse perfil nas cadelas castradas.

Abstract
We report on a 5-year-old boy who presented with postcardiotomy failure after aortic valve replacement and had to undergo implantation of a Berlin Heart-Excor system since treatment with ECMO did not improve myocardial pump function. After a stormy postoperative course with delayed sternal closure after 9 days, the young boy finally recovered and could be fully mobilized. Until successful heart transplantation after a support interval of 77 days, he experienced no device-related infectious or thromboembolic complications.

Abstract
Quantitative ultrasound (QUS) methods are promising tools for the assessment of the bone status in osteoporosis. The techniques are based on changes in speed and amplitude of a broadband ultrasound signal propagating through the bone. However, ultrasound propagation through the anisotropic bone is complex and cannot be described in a simple way. The devices are easy to use, inexpensive, portable, do not use ionizing radiation, and therefore have advantages compared to conventional densitometry. This review discusses the technical basics, current research, clinical applications, points of weakness, and future prospects of QUS. For better understanding ultrasound propagation through bone is visualized with a simulation software.

Abstract
Many wine connoisseur claim that the glass shape has a direct impact on wine aroma. This hypothesis was investigated in healthy volunteers (85 m, 96 f; age 19-73 years); 89 subjects received red wine, 92 subjects white wine. Subjects compared three glasses with a white wine and three glasses with a red. Glasses were of different shape but of the same height and of comparable opening diameter. All glasses had elegant stems; two glasses of 'tulip' and 'beaker'-like shapes were used in sessions with red and white wines. Different bulbous glasses were used in either red or white wine sessions. Subjects were blinded whether they received one or more wines. Intensity, hedonic tone, and quality of the wines were rated repeatedly before and after drinking. Ratings of wine odors from different glasses were influenced by glass shape. Importantly, this appeared not to relate to the esthetic impression the glasses made. Thus, the present data indicate that the shape of glasses seems to influence the perception of wine odors.

Abstract
BACKGROUND AND AIMS Interleukin-12 (IL-12), a p35/p40 heterodimer, plays a pivotal role in the immune response in Crohn's disease (CD). Since IL-12 p40 dimers act as IL-12 antagonists, we assayed p40 dimer proteins to modulate chronic intestinal inflammation. METHODS We generated a fusion protein consisting of the IL-12(p40) subunit fused to the constant region of IgG2b. IL-12(p40)-IgG2b was tested in a murine 2,4,6,-trinitrobenzene sulphonic acid (TNBS) colitis model and in lamina propria mononuclear cells (LPMNC) from patients with CD in vitro. RESULTS Dimeric IL-12(p40)-IgG2b fusion protein bound specifically to the IL-12 receptor. In concentrations <10(-7) M, it acted as an IL-12 antagonist as it inhibited interferon gamma (IFN-gamma) secretion, suppressed proliferation, and increased apoptosis of LPMNC from patients with CD. However, in concentrations >10(-6) M, IL-12(p40)-IgG2b increased IFN-gamma secretion and lymphocyte proliferation thereby acting as an IL-12 agonist. In TNBS colitic mice, IL-12(p40)-IgG2b decreased mortality (10% v 68%), prevented body weight loss, reduced tumour necrosis factor alpha, and increased IL-10 secretion. CONCLUSIONS The IL-12(p40)-IgG2b fusion protein has dichotomic properties as a specific IL-12 antagonist and selective repressor of mucosal inflammation at low concentration and as an IL-12 agonist at high concentration.

Abstract
In early clinical trials, the NK(1) receptor antagonist, aprepitant (EMEND(R)) was shown to improve the protection provided by the best available therapy (hereafter referred to as 'standard therapy': a 5-HT(3) receptor antagonist and dexamethasone) against chemotherapy-induced nausea and vomiting over multiple cycles of cisplatin-based chemotherapy. To further study the sustainment of antiemetic efficacy of aprepitant plus standard therapy over more than one cycle of chemotherapy, we examined combined data from the multiple cycles extensions of two phase III clinical trials of oral aprepitant plus standard therapy for the prevention of chemotherapy-induced nausea and vomiting. Data were pooled from two multicentre, randomised, double-blind, placebo-controlled studies with identical design and treatment regimens. Cancer patients receiving a first cycle of cisplatin-based (>or=70 mg/m(2)) chemotherapy were randomised to one of two treatment groups as follows: the standard therapy group received ondansetron 32 mg intravenously (i.v.) and dexamethasone 20 mg on day 1 and dexamethasone 8 mg twice daily (b.i.d.) on days 2-4. The aprepitant group received aprepitant 125 mg, ondansetron 32 mg i.v., and dexamethasone 12 mg on day 1, aprepitant 80 mg and dexamethasone 8 mg on days 2-3, and dexamethasone 8 mg on day 4. Patients had the option to receive the same blinded treatment for up to five additional cycles. The analysis used a combined exploratory endpoint of no emesis and no significant nausea (i.e. nausea which interfered with a patient's normal activities) over the 5 days following cisplatin, for up to six cycles of chemotherapy. A cumulative probabilities approach incorporating a model for transitional probabilities was used to analyse the data. Tolerability was assessed by reported adverse events and physical and laboratory assessments. Baseline characteristics, reasons for discontinuation, and drop-out rates were similar between groups. In every cycle, the estimated probabilities (rates) of no emesis and no significant nausea were significantly higher (P<0.006) in the aprepitant group: in the first cycle, rates were 61% in the aprepitant group (N=516) and 46% in the standard therapy group (N=522), and thereafter, rates for the aprepitant regimen remained higher throughout (59% (N=89) versus 40% (N=78) for the standard therapy, by cycle 6). Repeated dosing with aprepitant over multiple cycles was generally well tolerated. Compared with patients who received standard therapy alone (a 5-HT(3) antagonist plus dexamethasone), those who received aprepitant in addition to standard therapy had consistently better antiemetic protection that was well maintained over multiple cycles of highly emetogenic chemotherapy

Abstract
Recent clinical evidence suggests that positron emission tomography with fluorine-18 fluorodeoxyglucose (FDG-PET) is more accurate in detecting thyroid carcinomatous tissue at high than at low TSH levels. The aim of this study was to determine the influence of TSH on FDG uptake in human thyroid cells in vitro. Monolayers of human thyroid tissue were cultured after mechanical disintegration and enzymatic digestion of samples from patients undergoing surgery for nodular goitre. The purity of thyroid cell preparations was ascertained by immunohistochemical staining for the epithelial antigen KL-1, and their viability by measuring the synthesis of thyroglobulin in vitro. The cells were incubated with 0.8-1.5 MBq FDG/ml uptake medium for 1 h. FDG uptake in thyroid cells was quantified as percent of whole FDG activity per well (% ID) or as % ID in relation to total protein mass. This experimental protocol was subsequently varied to study the effect of incubation time, glucose dependency and TSH. Furthermore, radio-thin layer chromatography was used to identify intracellular FDG metabolites. FDG accumulated in the thyroid cells linearly with time, doubling roughly every 20 min. Uptake was competitively inhibited by unlabelled glucose and decreased to approximately 70% at 100 mg/dl glucose compared to the value measured in glucose-free medium. FDG was intracellularly trapped as FDG-6 phosphate and FDG-1,6-diphosphate. TSH significantly increased FDG uptake in vitro in a time- and concentration-dependent manner: Cells cultured at a TSH concentration of 50 micro U/ ml doubled FDG uptake compared to TSH-free conditions, and uptake after 72 h of TSH pre-incubation was approximately 300% of that without TSH pre-incubation. TSH stimulates FDG uptake by benign thyroid cells in a time- and concentration-dependent manner. This supports the clinical evidence that in well-differentiated thyroid carcinomas, most of which are still TSH-sensitive, FDG-PET is more accurate at high levels of TSH.
