Abstract
INTRODUCTION The optimal management of the urethra in patients planned for radical cystectomy (RC) remains unclear. We sought to evaluate the impact of urethrectomy on perioperative and oncological outcomes in patients treated with RC for non-metastatic urothelial carcinoma of the bladder (UCB). MATERIALS AND METHODS We assessed the retrospective data from patients treated with RC for UCB of five European University Hospitals. Associations of urethrectomy with progression-free (PFS), cancer-free (CSS), and overall (OS) survivals were assessed in univariable and multivariable Cox regression models. We performed a subgroup analysis in patients at high risk for urethral recurrence (UR) (urethral invasion and/or bladder neck invasion and/or multifocality and/or prostatic urethra involvement). RESULTS A total of 887 non-metastatic UCB patients were included. Among them, 146 patients underwent urethrectomy at the time of RC. Urethrectomy was performed more often in patients with urethral invasion, T3/4 tumor stage, CIS, positive frozen section analysis of the urethra, and those who received neoadjuvant chemotherapy, underwent robotic RC, and/or received an ileal conduit urinary diversion (all p < 0.001). Estimated blood loss and the postoperative complication rate were comparable between patients who received an urethrectomy and those who did not. Urethrectomy during RC was not associated with PFS (HR 0.83, p = 0.17), CSS (HR 0.93, p = 0.67), or OS (HR 1.08, p = 0.58). In the subgroup of 276 patients at high risk for UR, urethrectomy at the time of RC decreased the risk of progression (HR 0.58, p = 0.04). CONCLUSION In our study, urethrectomy at the time of RC seems to benefit only patients at high risk for UR. Adequate risk assessment of UCB patients' history may allow for better clinical decision-making and patient counseling.

Abstract
Flexible targeted helping is considered an advanced form of prosocial behavior in hominoids, as it requires the actor to assess different situations that a conspecific may be in, and to subsequently flexibly satisfy different needs of that partner depending on the nature of those situations. So far, apart from humans such behaviour has only been experimentally shown in chimpanzees and in Eurasian jays. Recent studies highlight the prosocial tendencies of several bird species, yet flexible targeted helping remained untested, largely due to methodological issues as such tasks are generally designed around tool-use, and very few bird species are capable of tool-use. Here, we tested Goffin's cockatoos, which proved to be skilled tool innovators in captivity, in a tool transfer task in which an actor had access to four different objects/tools and a partner to one of two different apparatuses that each required one of these tools to retrieve a reward. As expected from this species, we recorded playful object transfers across all conditions. Yet, importantly and similar to apes, three out of eight birds transferred the correct tool more often in the test condition than in a condition that also featured an apparatus but no partner. Furthermore, one of these birds transferred that correct tool first more often before transferring any other object in the test condition than in the no-partner condition, while the other two cockatoos were marginally non-significantly more likely to do so. Additionally, there was no difference in the likelihood of the correct tool being transferred first for either of the two apparatuses, suggesting that these birds flexibly adjusted what to transfer based on their partner´s need. Future studies should focus on explanations for the intra-specific variation of this behaviour, and should test other parrots and other large-brained birds to see how this can be generalized across the class and to investigate the evolutionary history of this trait.

Abstract
INTRODUCTION The aim of this study was to compare observation and early drainage by ureteral stenting in patients with blunt renal trauma and urinary extravasation. MATERIALS AND METHODS A retrospective national multicenter study was performed including all patients admitted for renal trauma at 17 hospitals between 2005 and 2015. Patients presenting with a urinary extravasation on initial imaging were considered for inclusion. Patients were divided in two groups according to the initial approach: observation vs. early drainage by ureteral stent (within 48 h after admission). The primary endpoint was the persistence of urinary extravasation on follow-up imaging. RESULTS Out of 1799 patients with renal trauma, 238 were included in the analysis (57 in the early drainage and 181 in the observation group). In the early drainage group, 29 patients had persistent urinary extravasation vs. 77 in the observation group (50.9% vs. 42.5%; p value = 0.27). The rates of secondary upper urinary tract drainage did not differ significantly between the early drainage group (26.4%) and the observation group (16%) (p = 0.14). There were no statistically significant differences between the two groups in terms of secondary nephrectomy (0% vs. 2.8%; p = 0.34), and death from trauma (0% vs. 1.8%; p = 0.99). In multivariate analysis, early drainage remained not statistically associated with persistence of urinary extravasation on follow-up imaging (OR = 1.35; p = 0.36) CONCLUSION: In this multicenter cohort, observation was not different from early drainage in terms of persistent urinary extravasation after grade IV blunt renal trauma. Further randomized controlled prospective trials are needed to confirm these findings.

Abstract
Background The German multicenter randomized phase II larynx organ preservation (LOP) trial DeLOS-II was carried out to prove the hypothesis that cetuximab (E) added to induction chemotherapy (IC) and radiotherapy improves laryngectomy-free survival (LFS; survival with preserved larynx) in locally advanced laryngeal/hypopharyngeal cancer (LHSCC). Patients and methods Treatment-naïve patients with stage III/IV LHSCC amenable to total laryngectomy (TL) were randomized to three cycles IC with TPF [docetaxel (T) and cisplatin (P) 75 mg/m2/day 1, 5-FU (F) 750 mg/m2/day days 1-5] followed by radiotherapy (69.6 Gy) without (A) or with (B) standard dose cetuximab for 16 weeks throughout IC and radiotherapy (TPFE). Response to first IC-cycle (IC-1) with ≥30% endoscopically estimated tumor surface shrinkage (ETSS) was used to define early responders; early salvage TL was recommended to non-responders. The primary objective was 24 months LFS above 35% in arm B. Results Of 180 patients randomized (July 2007 to September 2012), 173 fulfilled eligibility criteria (A/B: larynx 44/42, hypopharynx 41/46). Because of 4 therapy-related deaths among the first 64 randomized patients, 5-FU was omitted from IC in the subsequent 112 patients reducing further fatal toxicities. Thus, IC was TPF in 61 patients and TP in 112 patients, respectively. The primary objective (24 months LFS above 35%) was equally met by arms A (40/85, 47.1%) as well as B (41/88, 46.6%). One hundred and twenty-three early responders completed IC+RT; their overall response rates (TPF/TP) were 94.7%/87.2% in A versus 80%/86.0% in B. The 24 months overall survival (OS) rates were 68.2% and 69.3%. Conclusions Despite being accompanied by an elevated frequency in adverse events, the IC with TPF/TP plus cetuximab was feasible but showed no superiority to IC with TPF/TP regarding LFS and OS at 24 months. Both early response and 24 months LFS compare very well to previous LOP trials and recommend effective treatment selection and stratification by ETSS. Clinical trial information NCT00508664.

Abstract
This article aimed to gather male genital dermatoses that may lead to consult a urologist, except pre-neoplastic or neoplastic lesion. METHOD This review is based on a research on Pubmed and EM-consult database, in English and in French, using the following key terms "male genital dermatoses", "male genital lesions", "balanitis", "balanoposthitis", "dermatoses des organes génitaux externes masculines", "lésions des organes génitaux externes de l'homme", "balanoposthites". RESULTS It highlights normal morphological aspects, acute balanoposthitis (nonspecific, infectious, allergic, irritative and traumatic), common skin disease localized to male genital and male genital specific dermatoses. CONCLUSION Any suspicious, fixed, must lead to a skin biopsy.

Abstract
BACKGROUND Acute radiation dermatitis (ARD) is a frequent complication after breast cancer radiotherapy and is usually assessed by semi-quantitative clinical scores, which may be subject to inter-observer variability. High-frequency ultrasound imaging of the skin can reliably quantify thickness and edema in diseased skin. We aimed to compare the relative increase in dermal thickness of the irradiated zone in breast-cancer patients undergoing radiotherapy, with clinical severity. METHODS A consecutive series of patients undergoing treatment for breast cancer by lumpectomy and radiotherapy in a 6-month period also underwent clinical and ultrasound evaluation of ARD. RESULTS We included 34 female patients 17 had grade 1 (group 1), 17 had grade 2 or grade 3 ARD (group 2). The mean relative increase in dermal thickness in irradiated skin (RIDTIS) was greater for group 2 than 1: 0.53 vs 0.29 mm (P=.023). On univariate analysis, ARD was associated with skin phototype, breast volume and RIDTIS, and on multivariable analysis, breast volume and age remained predictive of the disease. CONCLUSION Patients with more severe dermatitis showed significantly increased dermal thickness. Dermal thickness is a quantitative variable that could help quantify the efficacy of drugs and improve the treatment of this disease in patients undergoing radiotherapy.

Abstract
INTRODUCTION The follow-up for head and neck cancer (HNC) focussed on therapy control. Accessory long term functionality is important. Impairment of function is observed, but a comparable documentation is not established. Additional we frequently see psychooncological comorbidities, what complicates the assessment. This was the reason why Tschiesner et al. developed on the base of the "ICF Core set for head and neck cancer" a guideline for the Assessment of Function in HNC. In consequence of good results in other tumour entities we developed an electronic version (OncoFunction). METHODS In a proof of concept study all patients of our follow up consultation from 07/13 to 03/14 were included. OncoFunction was given to patients in a digital form using tablet computers. The results were visible to the physician in a concentrated form before consultation and were supplemented by a physician questionnaire. Furthermore we evaluated the usability in 202 patients. RESULTS We had 682 patient contacts. 530 patient contacts (77, 7%) used the questionnaire. The physician questionnaire was answered in 470 times. Finally there are from 69.8% of the patient contacts full datasets available. Between users and non-users of the questionnaire we see no difference. CONCLUSION The use of a computer-based screening and feedback system (OncoFunction) in clinical use is feasible and excellent assessed by patients. The patient data are visible in a compact form for the physician and problems can clear addressed to the patient. One more benefit is the standardized follow up documentation and the use of comparable data in research.

Abstract
BACKGROUND Squamous cell carcinoma of the head and neck (SCCHN) is a common disease, which has a poor prognosis after failure of therapy. Activation of the PI3K-AKT-mTOR axis is commonly detected in recurrent or metastatic SCCHN, and provided the rationale for the clinical phase II trial in pretreated SCCHN. PATIENTS AND METHODS The primary end point was the progression-free survival rate (PFR) at 12 weeks. Forty eligible patients have been recruited after failure of platinum chemotherapy and cetuximab. A preplanned futility analysis was successfully passed after ≥1 success was detected in 20 patients. Secondary objectives consisted of progression-free survival (PFS), disease control rate (DCR), overall survival (OS), safety and tolerability, and predictive biomarkers for KRAS, BRAF, PIK3CA mutations, and HPV status. Archived tumor tissue was analyzed for DNA sequence. RESULTS A total of 40 patients were eligible. The PFR at 12 weeks was 40% (95% CI 25.0-54.6). The median PFS and OS were 56 days (95% CI 36-113 days) and 152 days (76-256 days), respectively. In 33 assessable patients, disease stabilization occurred in 57.6%, with tumor shrinkage in 13 patients (39.4%). Overall, the treatment was well tolerated. Fatigue (47.5%), anemia (25.0%), nausea (20.0%), and pneumonia (20.0%) were the most common adverse events. Neither PIK3CA mutations, nor HPV status were predictive for success with temsirolimus treatment. No mutations were found for KRAS or BRAF. CONCLUSION Tumor shrinkage and efficacy parameter indicate that inhibition of the PI3K-AKT-mTOR axis was a putative novel treatment paradigm for SCCHN. We could not identify parameters predictive for treatment success of temsirolimus, which underscores the need for refinement of the molecular analysis in future studies.

Abstract
Based on level I evidence, postoperative platinum-based radiochemotherapy (PORCT) is the recommended standard of care in defined risk situations after resection of squamous cell carcinomas of the larynx and hypopharynx (LHSCC). The value of the addition of chemotherapy to adjuvant radiation in intermediate and high risk situations other than extracapsular spread or R1-/R2 resection is still debated. From 1993 to 2009, 555 patients (median follow-up: 24.4 months) with advanced LHSCC (UICC stages III-IVB) were treated in a curative intent. Patient data were continuously documented in the county of Leipzig cancer registry and were retrospectively analyzed as mono institutional survey. PORCT was introduced into the standard procedures in 2004, but also applied before in selected cases. Based on this paradigm shift, the patient population was divided into two comparative groups treated before and after 2004. 361 patients were treated before 2004. 43.8 % received primary surgery (OP) + postoperative radiotherapy (PORT) and 20.2 % OP + PORCT. 194 patients were treated after 2004: 21.1 % received OP + PORT and 35.6 % OP + PORCT. Regarding the PORCT groups, 20.6 % received cisplatin plus 5FU before 2004 which shifted to 59.4 % after 2004. The 3-year tumor-specific-survival rate of the whole cohort was improved from 47 to 60 % (p = 0.006). The subgroup treated with OP + PORT or PORCT improved from 56.1 to 68.5 % (p = 0.028). Localization proved to be a significant and independent factor. Only patients with advanced laryngeal cancer had significant improved survival (p < 0.01), while the improvement for hypopharyngeal cancer patients was not significant (p < 0.2). After 2004, there was a slight increase (+10.2 %) of primary radiochemotherapy (pRCT) due to stronger selection if R0 > 5 mm-resectability is unlikely. Standardised use of PORCT and pRCT considering clear indications showed to be significantly involved in improved survival in advanced LHSCC.

Abstract
BACKGROUND The Head and Neck Cancer Tumor Board is a multispeciality comprehensive conference that brings together experts with different backgrounds to make group decisions about the appropriate treatment. Due to the complexity of the patient cases and the collaboration of different medical disciplines most of these decisions have to be made under uncertainty, i. e., with-out knowing all relevant factors and without being quite sure about the outcome. METHODS To develop effective team decision making under uncertainty, it is necessary to understand how medical experts perceive and handle uncertainties. The aim of this field study was to develop a knowledge base by exploring additionally the factors that influence group decision making processes. A structured nonparticipant observational study was employed to address the research goal. Video data were analyzed by 2 independent observers using an observation checklist. A total of 20 videotaped case discussions were studied. Observations were complemented by a questionnaire gathering subjective evaluations of board members about the process and quality of their decisions (N=15). RESULTS The results show that uncertainty is recognized by board members. Reasons for uncertainty may stem from the complexity of the cases (e. g. therapy options) or the assessment from different disciplines coming together at the board. CONCLUSION With respect to handling uncertainty and guaranteeing an optimal decision making process potential for improvement could be defined. This pertains to the handling of different levels of competence, the promotion of a positive discussion culture as well as structuring of the decision making process.

Abstract
BACKGROUND Cancer support groups provide information and coping resources as well as represent patients' interests. To date it is unknown how often cancer patients post-laryngectomy use support groups and in which parameters users of support groups differ from non-users. MATERIAL AND METHODS In a multicentre study, 224 laryngectomees were asked about their support group membership. Further, possible predictors for membership one year post-surgery were assessed. Data were collected with a semi-structured interview and standardized instruments. RESULTS Overall, 23% of the laryngectomized patients are actively involved in cancer support groups. The probability of a membership increases if patients are well-educated, are living in good economic conditions and in a partnership, if they perceive low family support and wish additional counselling with a physician. CONCLUSION A cancer support group seems to "buffer" family support perceived to be insufficient. However, support group users are living more frequently in a partnership and in good economic conditions compared to non-users. Physicians and speech therapists are important mediators to cancer support groups. They particularly should inform laryngectomees who are living in bad economic conditions and who are not living in a partnership about the availability of cancer support groups.

Abstract
This article presents the current data and discussion on multimodal laryngeal preservation strategies in advanced laryngeal/hypopharyngeal carcinoma. Principally a distinction is made between simultaneous and induction chemoradiation protocols. In terms of late toxicity and related functional limitations, induction protocols are far superior to simultaneous platinum-based chemoradiation. Currently, the individual response to the first cycle of (short) induction chemotherapy appears to be the most reliable clinical marker for making treatment decisions, and this is under clinical investigation. No standard multimodal therapeutic alternative to laryngectomy exists; therefore, at this time multimodal strategies should only be carried out within the framework of clinical trials.

Abstract
The ongoing development in therapies of head and neck malignomas has led to a further differentiation of treatment options. Complex surgical procedures, a wide variety of multi modal therapy options, changing radiation technologies (IMRT - Intensity-modulated radiation therapy) and numerous "targeted therapies" emphasize the need for a precise treatment plan. Beside this, imaging has seen significant improvements beyond the technical ones, e. g. with the implementation of PET/CT scanners. This increase in pre-therapeutic data volume, together with a diversification of treatment options calls for a further discussion of the basics of therapeutic decisions. Planning relevant data processing by computer assisted systems can aid in these decisions. This work describes the current status of relevant computer assisted systems undergoing first testing for head and neck cancer therapy planning. Here, the integration of 3-dimensional patient data plays a central role. This planning tool forms the integrated base for a further development in the areas of radiation planning, documentation and study management.

Abstract
Altered fractionated radiotherapy and concurrent chemoradiation could improve local control and survival for patients with locally advanced head and neck cancer. However, intensified treatment seems to increase late toxicity. Late swallowing dysfunction is common and has a large impact on quality of life and can get life-threatening character. Recent studies could show interrelations between the radiation dose to certain anatomical structures involved in the swallowing process and the risk of swallowing dysfunction. Important structures seem to be the pharyngeal constrictors and the supraglottic and glottic larynx. Further prospective clinical validations using standardized diagnostic protocols for dysphagia are necessary to establish dose constraints to anatomical structures involved in swallowing.

Abstract
Recurrent disease is one of the main reasons for the persistently poor prognosis of squamous cell carcinoma of the head and neck (HNSCC; European 5-year survival, 42%). The main treatment option for primary and secondary malignancy as well as recurrent disease is surgical therapy. If R0 resection (resection margin >5 mm) for a primary tumor is not viable, survival probability is reduced by 50%. In recurrent or secondary tumors with R1- or -2 resection or in the presence of non-resectable metastases, a palliative situation results in more than 80% of cases. In the case of surgery following radiotherapy or radiochemotherapy, attention should be paid to the criteria for salvage surgery (tissue perfusion, fibrosis, wound healing) and the procedure adapted to focus on functionality. In the case of relapse, primary surgery can potentially be supplemented with adjuvant therapy protocols such as (re-) irradiation, as well as possibly with chemotherapeutic agents or targeted therapies. Interdisciplinary collaboration and case discussions should take place in the context of a tumor board.

Abstract
There are a lot of diagnostic possibilities for the preoperative planning in head and neck surgery. So far, no study was performed to evaluate if there is an advantage of three-dimensional visualization compared to conventional computed tomography yet. Additionally, there are no specifications for such a visualization prior surgery in head and neck surgery. This work describes different possibilities for segmentation and three-dimensional visualization for preoperative planning in head and neck surgery and tumor volumetry compared to conventional computed tomography. We describe new techniques and specifications for three-dimensional visualization.

Abstract
Nanotechnology is an "emerging industry" and becomes more widely used. As a result human exposure to nanoparticles is inevitable. Exposure to nanoparticles can affect the upper aerodigestive tract, before particles reach lung, stomach and intestine. The effects of this passage depend on particle size, particle concentration, the kind of the particle and the duration of contact. Only few in-vitro-investigations about effects of the exposition of nanoparticles on the mucous cells of oral cavity, nose and nasal sinuses exist. In-vitro-analysis with cells of nasal mucous membrane exposed to nanoparticles showed a release of mediators involved in inflammation and allergy development. Cytotoxic and genotoxic effects could be found for several nanoparticles (e.g. carbon nanotubes) in vitro. Due to different size, structure, chemical and physical properties nanoparticles can not be summarized in a homogenous group; quite the contrary risk evaluation of nanoparticles must be carried out case-related. Today toxicological risks can not be evaluated sufficiently. Biological interactions and tissue permeability of manufactured nanoparticles is a major issue for further investigations. In this report the use and health effects of nanoparticles are overviewed.

Abstract
BACKGROUND Recent data suggest that, among other factors, comorbidity may be an important prognostic variable in patients with myelodysplastic syndromes (MDS) who are eligible for haematopoietic stem cell transplantation (SCT). PATIENTS AND METHODS We examined the overall survival (OS) and underlying risk factors in 45 adult patients with MDS (n = 38), chronic myelomonocytic leukaemia (n = 1), or secondary acute myeloid leukaemia (AML) arising from MDS (n = 6), who underwent allogeneic SCT at our Institution. RESULTS With a median follow-up of 37 months, OS for all patients was 23%, post-transplant relapse occurred in 11 patients, and 10 patients died from treatment-related complications. The overall outcome and survival was independent of cytogenetic abnormalities and International Prognostic Scoring System (IPSS). However, we identified comorbidity as defined by the haematopoietic cell transplantation specific comorbidity index (HCT-CI), as a significant adverse prognostic variable in our MDS patients. CONCLUSIONS Based on these data and similar published data we recommend selecting patients with MDS or secondary AML for SCT according to the presence of comorbidities.

Abstract
BACKGROUND The process of gastro-duodenal digestion may play a role in determining the allergenic properties of food proteins. The sensitizing and allergenic potential of digestion products of highly degraded allergens, such as the major peanut allergen Ara h 1, is currently under debate. We evaluated the effect of in vitro gastro-duodenal digestion of Ara h 1 on T cell reactivity and basophil histamine release. METHODS An in vitro model of gastro-duodenal digestion was used to investigate changes in the allergenic properties of Ara h 1 using in vitro assays monitoring T cell reactivity (proliferation, cytokine production) and histamine release of basophils from peanut allergic individuals. The digestion process was monitored using an SDS-PAGE gel. RESULTS In vitro gastric digestion led to rapid degradation of Ara h 1 into small fragments M(r) L5600. Gastric digestion did not affect the ability of Ara h 1 to stimulate cellular proliferation. Gastro-duodenal digestion significantly reduced its ability to stimulate clonal expansion (P<0,05; Wilxocon's signed rank test). The Th-2 type cytokine polarization of T cells from peanut allergic donors (IFN-gamma/IL-13 ratio and IFN-gamma/IL-4 ratio of CFSE(low) CD4(+) T cells) remained unchanged regardless of the level of digestion. Histamine release of basophils from peanut allergic individuals was induced to the same extent by native Ara h 1 and its digestion products. CONCLUSION Gastro-duodenal digestion fragments of Ara h 1 retain T cell stimulatory and IgE-binding and cross-linking properties of the intact protein.

Abstract
AIMS/HYPOTHESIS Although cells expressing insulin are detected early in human fetal development, islets isolated from fetal pancreases show poor insulin secretory responses to glucose, which may be the result of deficient glucose sensing. We have used dual and triple immunolabelling of human fetal and adult pancreas sections to investigate the presence of proteins that participate in glucose sensing in the pancreatic beta cell, namely glucose transporter 1 (GLUT 1, also known as SLC2A1), glucose transporter 2 (GLUT2, also known as SLC2A2), glucokinase (GCK) and inwardly rectifying K+ channel (KIR6.2, also known as KCNJ11) and sulphonylurea receptor 1 (SUR1, also known as ABCC8) subunits of ATP-sensitive K+ channels (K+(ATP) channels). MATERIALS AND METHODS Pancreases obtained with ethical approval from human fetuses from 11 to 36 weeks of gestation, from infants and from adults were formalin-fixed and embedded in paraffin. Sections were labelled with antibodies to proteins of interest. Co-production of antigens was examined by dual and triple immunolabelling. RESULTS GLUT2 and K+(ATP) channel labelling was detected in the 11-week pancreas, but largely within the pancreatic epithelium, whereas no labelling for GLUT1 was observed. From 15 weeks, GLUT1, GCK and K+(ATP) channel labelling was detected in an increasing proportion of insulin-positive cells and epithelial labelling with K+(ATP) channel antibodies diminished. GLUT2 was seen in the majority of beta cells only after 7 months of age. CONCLUSIONS/INTERPRETATION The results demonstrate that only a subpopulation of beta cells in the human fetal pancreas produce all key elements of the glucose-sensing apparatus, which may contribute to poor secretory responses in early life.

Abstract
Experimental data on cortical reorganization in blind subjects using H(2)(15)O positron emission tomography and functional magnetic resonance imaging (fMRI) showed activation of the visual cortex related to Braille reading and tactile discrimination tasks in congenitally and early blind subjects. The purpose of our study was to differentiate whether occipital activation of blind subjects during Braille reading is task specific or only triggered by sensory or motor area activation. Twelve congenitally and early-onset blind subjects were studied with fMRI during Braille reading, discriminating nonsense dots, sensory stimulation with electromagnetic pulses, and finger tapping. All experiments were performed utilizing a block design with 6 active epochs alternating with 6 rest conditions lasting 34 s each. Echo-planar imaging sequences with 34 transversal slices were performed on a 1.5-T MR scanner. All blind individuals reading Braille and discriminating nonsense dots showed robust activation of the primary, secondary, and higher visual cortex. Application of peripheral electrical stimuli to the reading hand revealed expected sensory activation of the primary somatosensory cortex, but no activation in the visual cortex. Pure motor activation during finger tapping with the reading hand showed expected precentral activation and no activation of visual cortex. In conclusion, occipital activation during Braille reading and discrimination tasks is not due to plasticity of sensory or motor function; pure motor or sensory tasks do not lead to an activation of striate cortex. The brain learns to differentiate between "finger touching" and "finger reading." Our results suggest that activation of the visual cortex in blind subjects is related to higher and more complex brain functions.

Abstract
This pediatric intensive care unit (PICU) functions as a part of a multidisciplinary adult ICU and has evolved into a unique health care setting. The Special Care Unit (SCU), which is the name for our ICU, serves a population of adult and pediatric patients, including trauma, open-heart surgery, medicine, surgery, and neurosurgery. All staff are expected to provide care for adults and children without regard to admitting diagnosis. In addition to meeting the critical care needs of this diverse pediatric population in the SCU, we provide a pediatric critical care ground transport program for critically ill children from outlying hospitals. Competency-based orientation tools were developed and are used to guide the orientation process. The tools identify the required knowledge base necessary for a staff member to adequately care for the adult and pediatric populations and track each staff member's progress through orientation. The model used to deliver care to adults and children in this setting is innovative. This model represents one solution to providing critical care to both the adult and pediatric population in today's era of health care redesign.

Abstract
The authors identify the influence of organizational and personal characteristics on the tendencies of community organizational workers in Israel to implement planning activities. The research examines these factors in relation to two planning styles, rational and organizational-political, and also distinguishes among factors influencing the tendency for implementation of each style. The principal findings indicate that the tendency of workers to implement rational activities is influenced by mechanical characteristics of the organization. On the other hand, the tendency of the workers to implement organizational-political activities is influenced significantly by organic characteristics--variety and conflict--with the organization. The frequency of use of both styles is influenced by professional education in community organization.

Abstract
The properties of diphencyprone (DPC), its possible mechanism of action in the therapy of alopecia areata (AA), and its side-effects are summarized. The results of our own study of treatment in 45 patients with AA, with a mean treatment duration of 72 (15-146) weeks, are presented, and compared with the results of previous studies. We suggest that, in future, therapy protocols should define entry criteria and therapy results more precisely, and include follow-up assessments to establish the length of remission. In view of the low response rates and short lengths of remission, the indications for DPC therapy should be set more rigorously.

Abstract
The results of gunshot residue (GSR) tests in 112 suicide cases investigated by the U.S. Army Criminal Investigation Command over a ten-year period are described. Only suicide cases in which there was certainty that the victim fired a weapon were examined in an effort to reduce ambiguous results. Previous case work research by Rudzitis indicated that positive GSR test results were encountered in suicides 62% of the time using various combinations of neutron activation analysis (NAA) and atomic absorption spectrophotometry (AAS). Threshold values of 0.2-micrograms antimony and 0.3-micrograms barium (0.2-micrograms antimony and 0.5-micrograms barium after 1985) used by the U.S. Army Criminal Investigation Laboratory resulted in positive GSR results in suicide cases 38% of the time. The effects of time, location of body, handling of the body, weapon type, caliber, and condition of the hands on GSR results are examined. Case studies involving suicides by unit armorers are discussed.

Abstract
Both thromboxane A2 (TXA2) and its precursor prostaglandin H2 (PGH2) are labile and share a common receptor. The affinities of these two compounds for their putative common receptor are unknown. We compared the potencies of TXA2 and PGH2 to aggregate human platelets and bind to the TXA2/PGH2 receptor. TXA2 was more potent than PGH2 in initiating aggregation in platelet-rich plasma, EC50 of 66 +/- 15 nM and 2.5 +/- 1.3 microM, respectively. In washed platelets, however, PGH2 was more potent than TXA2 with EC50 values of 45 +/- 2 nM and 163 +/- 21 nM, respectively. The affinity of these two compounds in washed platelets was determined in radioligand competition binding assays employing [125I]-PTA-OH. The Kd values for PGH2 and TXA2 were 43 nM and 125 nM, respectively. The results demonstrate that the affinity of PGH2 for the platelet TXA2/PGH2 receptor is greater than previously thought. The data raise the possibility that PGH2 may significantly contribute to the responses attributed to TXA2 in vivo.
