Abstract
BACKGROUND Papillary-serous adenocarcinoma (PSCC) is a very rare subtype of cervical cancer. To our knowledge, this is the first report on PSCC of the uterine cervix following bilateral breast cancer. CASE REPORT A 61-year-old Caucasian woman underwent conserving surgery of both breasts at the age of 57 years, because of bilateral invasive ductal carcinoma. Radiation and tamoxifen treatment followed. Routine surveillance examinations, including pelvic examination, Papanicolaou (Pap) smear, and transvaginal ultrasound, were uneventful. Recently, a small contact-bleeding mass of the cervix was found. The Pap smear was II (reactive); HPV-DNA test was negative. The biopsy of the mass revealed PSCC with a high expression of p53, carcinoembryonic antigen (CEA), and Ki67 (50%). Staining for estrogen receptor (ER), progesterone receptor (PR), and vimentin was negative. The serum carbohydrate antigen 125 (CA-125) reached 159 U/ml. The patient was treated with radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic and paraaortic lymphadenectomy. A poorly-differentiated papillary-serous, non-secretory adenocarcinoma, pT1b1, pN0 (0/44), pM0, G3, R0, V0, L0, was confirmed. According to the German recommendations for early-stage cervical cancer, the patient received no adjuvant treatment. Currently, the patient is free of relapse 38 months after the diagnosis of cervical cancer and 87 months after that of breast cancer. CONCLUSION Immunohistochemistry is helpful in diagnosing rare entities. This case adds further evidence that the prognosis for early-stage PSCC is probably not poorer than that for other cervical adenocarcinomas.

Abstract
BACKGROUND Neuroendocrine breast carcinomas (NEC) are rare. Carcinomas with mixed composition often behave differently from 'pure' histological types, and the prognosis is determined by the proportion of the more aggressive tumour. The molecular classification helps in making therapeutic decisions. CASE REPORT A 56-year-old Caucasian woman with palpable and preoperatively biopsied breast tumour was treated with breast-conserving surgery. The histological specimen revealed a 17-mm invasive carcinoma with an equal proportion of neuroendocrine and invasive-ductal differentiation, accompanied by peritumoural ductal carcinoma in situ. TNM classification was pT1c(is), pN0 (0/1sn), G3, L0, V0, Pn0, R0. The diagnosis was enhanced by immunohistochemistry: high positivity for synaptophysin, neuron-specific enolase (NSE), neural cell adhesion molecule (CD56), Ki-67 (proliferation index 46%), estrogen receptor (ER) and progesterone receptor (PR), negative for Her-2-neu and cytokeratin 5/6, resulting in diagnosis of the molecular 'luminal B' subtype. Radiation and adjuvant chemotherapy with six cycles of 5-fluorouracil, epirubicin and cyclophosphamide, followed by tamoxifen and subsequent exemestane for five years, were recommended. CONCLUSION Immunohistochemistry plays a crucial role in the diagnosis of rare cancer subtypes. NEC is characterized by high biological aggressiveness. Molecular classification facilitates therapeutic decisions.

Abstract
The medial nucleus of the trapezoid body (MNTB) is a vital structure of sound localization circuits in the auditory brainstem. Each principal cell of MNTB is contacted by a very large presynaptic glutamatergic terminal, the calyx of Held. The MNTB principal cells themselves are surrounded by extracellular matrix components forming prominent perineuronal nets (PNs). Throughout the CNS, PNs, which form lattice-like structures around the somata and proximal dendrites, are associated with distinct types of neurons. PNs are highly enriched in hyaluronan and chondroitin sulfate proteoglycans therefore providing a charged surface structure surrounding the cell body and proximal neurites of these neurons. The localization and composition of PNs have lead investigators to a number of hypotheses about their functions including: creating a specific extracellular ionic milieu around these neurons, stabilizing synapses, and influencing the outgrowth of axons. However, presently the precise functions of PNs are still quite unclear primarily due to the lack of an ideal experimental model system that is highly enriched in PNs and in which the synaptic transmission properties can be precisely measured. The MNTB principal cells could offer such a model, since they have been extensively characterized electrophysiologically. However, extracellular matrix (ECM) in these neurons has not yet been precisely detailed. The present study gives a detailed examination of the ECM organization and structural differences in PNs of the mouse MNTB. The different PN components and their distribution pattern are scrutinized throughout the MNTB. The data are complemented by electron microscopic investigations of the unique ultrastructural localization of PN-components and their interrelation with distinct pre- and postsynaptic MNTB cell structures. Therefore, we believe this work identifies the MNTB as an ideal system for studying PN function.

Abstract
BACKGROUND Case management provided by health care assistants (HCAs) is effective in improving primary care for depressive patients. Little is known on the implementation-related aspects of case management performed in small family practices. OBJECTIVE To explore family doctors' perspectives on clinical and organizational aspects of implementation of case management and perceived practice-related aspects associated with patient care after 1 year's experience of HCAs providing case management for depressive patients in their practices. METHODS This qualitative study was nested in a cluster-randomized trial on case management provided by practice-based HCAs for patients with major depression in Germany. We used semi-structured interview guides and performed audio-taped interviews with family doctors. Full transcription and thematic content analysis were carried out. RESULTS Twenty-three family doctors were interviewed. The family doctors perceived case management as beneficial to patients and reported that it improved their consultation styles and doctor-patient relationships. They implemented case management elements into their everyday day work using 'concrete', 'subsumed' or 'progressive' implementation styles. CONCLUSIONS Family doctors perceived practice-based case management by HCAs as beneficial for patient care. Different implementation styles may be appropriate, depending on the health care setting, and this requires further evaluation.

Abstract
OBJECTIVE Decompression of all four muscle compartments of the lower leg to normalize tissue pressure and prevent permanent neuromuscular dysfunction. INDICATIONS Incipient compartment syndrome (characterized by excessive pain, muscle pain on extension, tensely swollen and shiny skin, and Δp>30 mmHg without neuromuscular deficit) and no clinical improvement after conservative treatment and/or acute compartment syndrome (symptoms as for incipient compartment syndrome with neuromuscular deficit and Δp<30 mmHg). CONTRAINDICATIONS None. There is some dispute about indications and timing of fasciotomy and necrectomy when the need for dermatofasciotomy is recognized late (e.g. intubated intensive care patients). SURGICAL TECHNIQUE In unilateral compartment release as described by Matsen, the lateral compartment is decompressed first through a parafibular approach. After identification of the anterior and superficial posterior compartments by transverse incision of the fasciae, these muscles are also decompressed longitudinally. Finally, the deep posterior compartment beneath the lateral compartment is decompressed. In bilateral dermatofasciotomy, the fasciae of the anterior and lateral compartments are incised through a proximal anterolateral approach and the superficial and deep posterior compartments through a distal dorsomedial approach. POSTOPERATIVE MANAGEMENT Synthetic skin substitute or vacuum-assisted wound closure until definitive closure by secondary suture or mesh grafting after about 5 days. Patient mobilization generally depends on the concomitant bone injury. RESULTS During the period from October 2001 to November 2008, 37 dermatofasciotomies were performed at our hospital to treat acute posttraumatic compartment syndrome. On the day of dismissal, symptoms of neuromuscular dysfunction after acute compartment syndrome had not disappeared completely in 5 patients. One patient received intermittent dialysis for acute kidney failure after crush syndrome. There were perioperative complications in a total of 6 patients: iatrogenic neurotomy (n=1), hematoma requiring revision (n=2), deep wound infection (n=2), and superficial disturbed wound healing (n=1).

Abstract
The biological basis for the selective vulnerability of neurons in Alzheimer's disease (AD) is elusive. Aggrecan-based perineuronal nets (PNs) of the extracellular matrix have been considered to contribute to neuroprotection in the cerebral cortex. In the present study, we investigated the organization of the aggrecan-based extracellular matrix in subcortical regions known to be preferentially affected by tau pathology in AD. Immunocytochemistry of aggrecan core protein was combined with detection of neurofibrillary degeneration. The results show that many regions affected by tau pathology in AD, such as the basal nucleus of Meynert, the dorsal thalamus, hypothalamic nuclei, raphe nuclei, and the locus coeruleus were devoid of a characteristic aggrecan-based extracellular matrix. Regions composed of nuclei with clearly different intensity of tau pathology, such as the amygdala, the thalamus and the oculomotor complex, showed largely complementary distribution patterns of neurofibrillary tangles and PNs. Quantification in the rostral interstitial nucleus of the longitudinal fascicle potentially affected by tau pathology in AD revealed that tau pathology was not accompanied by loss of aggrecan-based PNs. Neuro-fibrillary tangles in net-associated neurons extremely rarely occurred in the pontine reticular formation. We conclude that the low vulnerability of neurons ensheathed by PNs previously described for cortical areas in AD represents a more general phenomenon that also applies to subcortical regions. The aggrecan-based extracellular matrix of PNs may thus, be involved in neuroprotection.

Abstract
From a care provider's view quality of care should, of course, be the major focus. But should results such as employer quality, quality of cooperation, and the economic outcome not be treated as equally important aims since they interact mutually? By analyzing impacts on the quality of care, we found direct factors like the quality of applied procedures or clinical pathways influenced by secondary factors like quality assurance and research, for instance. As expected, all of these factors are essentially involved by the human factor. In order to sustainably improve results in health care, the human factor requires a new attendance and should be addressed in dimensions of results that are as important as quality of care itself. Optimizing the human factor in health care is a prerequisite to sustainably improve quality and requires an advanced point of view on dimensions of results that mutually interact with the quality of care: Focus on the patient. In order to achieve this goal, we have to primarily focus on the organization hospital.

Abstract
Arnica preparations have long been used for the symptomatic treatment of rheumatic complaints and recent clinical trials have demonstrated the beneficial effects of Arnica preparations in the treatment of osteoarthritis (OA). The efficacy of Arnica is presumed to be mainly due to its anti-inflammatory properties and inhibition of the transcription factor NF-kappaB. Here we provide further insights into its molecular mode of action. Arnica preparations suppress MMP1 and MMP13 mRNA levels in bovine and human articular chondrocytes in a concentration-dependent manner and in a low concentration range. This suppression may be due to inhibition of DNA binding of the transcription factors AP-1 and NF-kappaB. Interestingly, sesquiterpene lactones present in the preparations were always more active than the pure compounds, demonstrating the advantage of using plant preparations.

Abstract
INTRODUCTION Laparoscopic resection of rectal cancer has been proven efficacious but morbidity and oncological outcome need to be investigated in a randomized clinical trial. TRIAL DESIGN Non-inferiority randomized clinical trial. METHODS The COLOR II trial is an ongoing international randomized clinical trial. Currently 27 hospitals from Europe, South Korea and Canada are including patients. The primary endpoint is loco-regional recurrence rate three years post-operatively. Secondary endpoints cover quality of life, overall and disease free survival, post-operative morbidity and health economy analysis. RESULTS By July 2008, 27 hospitals from the Netherlands, Belgium, Germany, Sweden, Spain, Denmark, South Korea and Canada had included 739 patients. The intra-operative conversion rate in the laparoscopic group was 17%. Distribution of age, location of the tumor and radiotherapy were equal in both treatment groups. Most tumors are located in the mid-rectum (41%). CONCLUSION Laparoscopic surgery in the treatment of rectal cancer is feasible. The results and safety of laparoscopic surgery in the treatment of rectal cancer remain unknown, but are subject of interim analysis within the COLOR II trial. Completion of inclusion is expected by the end of 2009. TRIAL REGISTRATION Clinicaltrials.gov, identifier: NCT00297791 (www.clinicaltrials.gov).

Abstract
GOLPH2 is coding the 73-kDa type II Golgi membrane antigen GOLPH2/GP73. Upregulation of GOLPH2 mRNA has been recently reported in expression array analyses of prostate cancer. As GOLPH2 protein expression in prostate tissues is currently unknown, this study aimed at a comprehensive analysis of GOLPH2 protein in benign and malignant prostate lesions. Immunohistochemically detected GOLPH2 protein expression was compared with the basal cell marker p63 and the prostate cancer marker alpha-methylacyl-CoA racemase (AMACR) in 614 radical prostatectomy specimens. GOLPH2 exhibited a perinuclear Golgi-type staining pattern and was preferentially seen in prostatic gland epithelia. Using a semiquantitative staining intensity score, GOLPH2 expression was significantly higher in prostate cancer glands compared with normal glands (P<0.001). GOLPH2 protein was upregulated in 567 of 614 tumours (92.3%) and AMACR in 583 of 614 tumours (95%) (correlation coefficient 0.113, P = 0.005). Importantly, GOLPH2 immunohistochemistry exhibited a lower level of intratumoral heterogeneity (25 vs 45%). Further, GOLPH2 upregulation was detected in 26 of 31 (84%) AMACR-negative prostate cancer cases. These data clearly suggest GOLPH2 as an additional ancillary positive marker for tissue-based diagnosis of prostate cancer.

The method requires two scans where the difference signal is equivalent to the I spin magnetization that is transferred to the S spins. The acquired signal is equivalent to F1 sum projection of a two-dimensional (2D) heteronuclear correlation experiment and is obtained by just two scans without the need to increment the indirect time domain t(1). Any polarization transfer method and any kind of spin manipulations during the t(1) incrementation period of a 2D NMR experiment can be applied. The method allows fast measurements of the CP transfer, particularly if various S spins signal overlap and is good for spectral editing of I spin signals with contact to S spins. Various examples for biomaterials are presented. Most importantly, this novel approach is ideal for detailed investigations of organic-mineral interfaces in bone, here demonstrated for O-phospho-l-serine as simple model compound.
