Abstract
Abstract Transthyretin (TTR)-related cardiac amyloidosis is a progressive infiltrative cardiomyopathy that mimics hypertensive, hypertrophic heart disease and may go undiagnosed. We here report the case of a 83-year-old woman, which has rapresented an unique case of transthyretin-related cardiac amyloidosis, as a patient with an initial diagnosis of hypertensive heart disease later develops an infiltrative cardiomyopathy due to amyloid deposits.

Abstract
PURPOSE/OBJECTIVE(S) To model in a subset of patients from TROG 07.03 managed at a single site the association between domiciliary based humidification use and mucositis symptom burden during radiotherapy (RT) for head and neck cancer (HNC) when factoring in volumetric radiotherapy parameters derived from tumour and normal tissue regions of interest. MATERIALS/METHODS From June 2008 through June 2011, 210 patients with HNC receiving RT were randomised to either a control arm or humidification using the Fisher & Paykel Healthcare MR880 humidifier. This subset analysis involves patients recruited from Auckland City Hospital treated with a prescribed dose of ≥70 Gy. Regression models included control variables for Planning Target Volume 70 GY (PTV70Gy); Equivalent Uniform Dose (EUD) MOIST and TSV (surrogates of total mucosal and total swallowing volumes respectively). RESULTS The analysis included 39 patients (humidification 20, control 19). There was a significant odds reduction in CTCAE v3.0 functional mucositis score of 0.29 associated with the use of humidification (p<.001). Within the parameters of the model therefore, the risk of a humidification patient being scored as experiencing a one-step increase in functional mucositis was 3.45 times lower (1/0.29) than for control patients. A control patient was 4.17 times more likely to receive an unfavourable nutritional mode score (p<.001). The risk of being admitted to hospital decreased by a factor of 11.11 for humidification patients (p=.013). CONCLUSION The results support the hypothesis that humidification can help mitigate mucositis symptom burden. Radiotherapy dosimetric parameters assist in the evaluation of toxicity interventions.

Abstract
Several evidences suggest that the Amastigote Surface Protein-2 (ASP-2) of Trypanosoma cruzi is an important target for immunity during infection. Based on this, we considered it important to evaluate its strain polymorphism. Initially, we observed the presence of conserved cross-reactive epitopes in amastigotes of all parasite strains tested. In addition, the predicted amino acid sequences of the genes isolated from the cDNA of amastigotes of CL-Brener, Tulahuen, Colombian and G strains displayed a high degree of identity (>80%) to the previously described genes of ASP-2. Unexpectedly, Sylvio X10/4 and G strains expressed a new isoform of ASP-2 with limited identity to the previously described genes, but with a high degree of identity when compared to each other. Immunological studies confirmed the presence of cross-reactive epitopes between recombinant proteins representing the different isoforms of ASP-2. However, the genetic vaccination of mice with the new isoform of asp-2 gene expressed by the G strain failed to provide the same degree of protective immunity to a challenge by parasites of the Y strain as did asp-2 genes of Y or CL-Brener strains. In summary, we found that few strains can express different isoforms of ASP-2 which may not share cross-protective epitopes.

Abstract
The pharmacokinetics and mammary excretion of imidocarb dipropionate, a therapeutic/prophylactic agent against a variety of tick-borne hemoparasitic diseases in domestic animals, have been investigated in sheep and goats. A commercial formulation of imidocarb di-propionate was injected i.m. at a single dose of 3 mg/kg of body weight in 7 mature lactating ewes and 8 lactating does in good health. Blood samples were collected for 48 h after administration and milk samples were collected every 12 h for 10 d. A weak cation-exchange solid-phase procedure was used to remove imidocarb from plasma. A hexane/isoamyl alcohol liquid-liquid procedure was adopted to extract the drug from the milk of sheep. The same method was used for goat milk after exposing the matrices to enzymatic digestion. The extracted samples were analyzed by HPLC. The i.m. disposition kinetics of imidocarb in the 2 species showed significant differences in the rate of elimination (0.0075 +/- 0.002 and 0.025 +/- 0.004 L/h in sheep and goats, respectively), being faster in ewes than in does. Nevertheless, a smaller area under the concentration-time curve (12.21 +/- 0.76 and 9.49 +/- 0.54 microg/mL per h in sheep and goats, respectively), a larger volume of distribution (4.18 +/- 0.44 and 7.68 +/- 0.57 L/kg in sheep and goats, respectively), and a longer mean residence time (9.07 +/- 0.77 and 14.75 +/- 2.20 h in sheep and goats, respectively) were found in goats, suggesting a more rapid and effective drug storage in tissues during the first 48 h after the injection. The concentrations of imidocarb in milk of both species were higher than in plasma. However, a fast passage through the blood-milk barrier and a high storage of imidocarb were observed in the milk of ewes, whereas the drug concentrations were not as high nor was the extent of drug penetration from blood to milk as great in the milk of goats (AUC(milk 0-48)/AUC(plasma 0-48) = 2.5 +/- 0.45 and 1.26 +/- 0.27 in sheep and goat, respectively). Despite the differences in pharmacokinetic behavior, and considering the sensitivity of pathogens to imidocarb, the same dosage regimen can be used for clinical efficacy against Babesia spp. infection in both species. In contrast, the differences in depletion of imidocarb residue in milk and the large variability in mammary drug elimination found in goats suggests that great care should be taken in defining the withdrawal time in small ruminant dairy species.

Abstract
Our purpose was to evaluate a pharmacological and dietary protocol of prophylaxis and treatment of acute actinic esophagitis during mediastinal radiotherapy. This phase II study was conducted on 29 patients affected by cancer not directly involving the esophagus. The irradiated volume included at least 10 cm of esophagus with a median dose of 46 Gy and the incidence of clinical acute esophagitis was scored with RTOG-EORTC tables. During the entire course of radiation therapy all patients were subjected to prophylaxis pharmacological therapy in addition to dietetic rules commonly used. All patients were evaluable, 9 (31%) had no acute esophageal toxicity, 20 (69%) had toxicity of degree 1, and no patient showed a toxicity of degree 2, 3, or 4, there were no toxicity-related related interruptions of the radiotherapy course. In conclusion, this low cost protocol seems to reduce the incidence and degree of acute radiation esophagitis (without added morbidity), compared with literature reports.

Abstract
BACKGROUND Dermoscopy is a noninvasive technique that increases the diagnostic accuracy of pigmented skin lesions, particularly improving the diagnosis of patients with cutaneous melanoma in situ (CMIS) and early invasive melanoma. To establish reliable and reproducible dermoscopic criteria for the diagnosis of CMIS, the authors conducted a retrospective clinical study of 37 patients with CMIS and 53 patients with invasive cutaneous melanomas (ICM). METHODS The 37 patients with CMIS were divided into three groups: those with CMIS lesions measuring < or = 5 mm in greatest dimension (8 patients), those with CMIS lesions measuring from > 5 mm to < or = 10 mm in greatest dimension (20 patients), and those with CMIS lesions measuring > 10 mm in greatest dimension (9 patients). The 53 patients with ICM were divided into two groups according to Breslow index: those with ICM lesions measuring < or = 0.75 mm in tumor thickness (19 patients) and those with ICM lesions measuring > 0.75 mm in tumor thickness (34 patients). Lesions were examined with a dermatoscope and were photographed at a magnification of x10. Dermoscopic criteria were evaluated from examination of the photomicrographs. RESULTS Blue-whitish veil, gray-blue areas, black dots, and irregular extensions and branched streaks were the most relevant dermoscopic criteria for CMIS and were present in 78%, 76%, 73%, and 62% of lesions, respectively. Brown globules, irregular pigment network, pseudopods, and depigmentation were present in 57%, 54%, 54%, and 51% of CMIS lesions, respectively. White scar-like areas and linear and/or dotted vascular patterns, two criteria that are associated frequently with ICM, were not found in our patients with CMIS. No clinically significant differences were observed between the three groups of CMIS patients. CONCLUSIONS Dermoscopic criteria for CMIS were similar to those for ICM, although white scar-like areas and linear and/or dotted vascular patterns were observed only in patients with ICM. Dermoscopic criteria appeared to be independent of CMIS lesions size.

Abstract
PURPOSE To evaluate exclusive high-dose-rate brachytherapy for localized early-stage non-small-cell bronchial carcinoma; to develop new insights in treatment-catheter positioning and tumor-volume assessment by computed tomography (CT) scan. METHODS AND MATERIALS Between 1992 and 1996, 34 patients with non-small-cell bronchial carcinoma were treated by brachytherapy alone. All patients were medically inoperable and had contraindications for external beam irradiation. The treatment protocol was six sessions of 5 Gy over 6 weeks. The treatment catheter was placed under fiberoscopy and was positioned with the help of spacer catheters or with a surrounding plastic tube; CT scan was performed in 50% of the cases to measure the spacing between the applicator and the bronchial wall. Dose prescription was individually based on clinical and radiologic evaluation of tumor volume. RESULTS Local disease failure occurred in 5 patients (15%). With a median follow-up of 2 years, the local control rate was 85% and the survival rate 78%. No acute toxicity was found, except one pneumothorax. CONCLUSION Brachytherapy alone can give an optimal therapeutic ratio in small endobronchial carcinomas without radiation-induced morbidity. Such results are achieved after careful tumor volume evaluation and individualized treatment catheter positioning.

Abstract
We evaluated the feasibility of local school personnel conducting functional analysis and reinforcement-based treatment procedures within actual classroom settings. Following an initial in-service workshop on functional assessment and differential reinforcement procedures, on-site technical assistance was provided two to four times per month to local school personnel working in transdisciplinary teams. Overall results suggest that local school personnel were able to implement all procedures adequately with periodic technical assistance. In addition, functional analysis was effective in identifying individual maintaining contingencies, the derived treatments were effective, and the results were maintained throughout the approximate 18 months of this investigation.

Abstract
We conducted a functional analysis of distinct topographies of aberrant behavior displayed by 4 clients. We first analyzed the behaviors in an aggregate fashion and then separated the behaviors to formulate hypotheses about the maintaining variables for each behavior. The procedures were used in a two-phase experiment. During Phase 1, two extended functional analyses were completed, one in an inpatient unit and one in a special education classroom. During Phase 2, two brief functional analyses were completed in an outpatient clinic. Results indicated that hypotheses of separate functions for distinct behaviors can be generated using both extended and brief functional analyses when the results are graphed in the aggregate and are separated by response topography. The results also suggest that these methods can improve the accuracy of data interpretation and treatment selection.

Abstract
The impact of the article by Iwata, Dorsey, Slifer, Bauman, and Richman (1982) on research in severe behavior disorders has been impressive. Equally impressive, however, but not as fully recognized, has been the impact of this methodology on the routine professional activities of those who employ functional analysis methods in their daily work. As one example of this impact, we describe the evolution of assessment procedures based on "brief functional analysis" methodology in our outpatient clinics. Less apparent have been the collateral effects that occur from using these procedures. Interactions with clients and colleagues have changed in ways that result in increased positive reinforcement. In this article, we briefly discuss the positive impact functional analysis has had on one specific work behavior--outpatient clinic assessment--and describe some of the generalized effects we have experienced in related aspects of our daily professional activities.

Abstract
A facile and regiocontrolled procedure for the preparation of 5-beta-cholestane-3 alpha,7 alpha,12 alpha,25-tetrol-3-O-beta-D-glucuronide and its corresponding C-26 analogue is described. The method involves direct coupling of bile alcohols, namely, 5 beta-cholestane-3 alpha,7 alpha,12 alpha,25-tetrol and 24-nor-5 beta-cholestane-3 alpha,7 alpha,12 alpha,25-tetrol to methyl (tetra-O-acetyl-beta-D-glucopyranuronate) in the presence of a Lewis acid, tin(IV) chloride, in dichloromethane. The resulting anomeric pairs of 1,2-trans- and 1,2-cis-glucuronides of tetrols were resolved by analytical and preparative thin-layer chromatography, and their identities were established by high-resolution 1H NMR spectroscopy and by chemical-ionization and fast-atom-bombardment mass spectrometry. The method described has a practical advantage over the traditional two-step synthesis involving bromides as it is more efficient and uses inexpensive and less toxic materials. It is suggested that these compounds will be useful for studying permeability of the blood-brain barrier in cerebrotendinous xanthomatosis (CTX).

Abstract
Previous investigators have analyzed the maintaining conditions for aberrant behaviors using brief functional assessment procedures. These assessment procedures have been used in one of our outpatient clinics, the Self-Injurious and Aggressive Behavior Service. This study presents a descriptive summary of the results from 79 cases during a 3-year period. The outcomes of the brief assessment were evaluated across three variables: (a) referring topography, (b) control over behavior as evaluated through brief multielement designs, and (c) the identified maintaining conditions for aberrant behavior. The limitations and future utility of brief functional assessments for identifying distinct maintaining contingencies are discussed.

Abstract
We conducted a brief functional analysis to identify maintaining variable for aggressive behavior and an alternative replacement response during a 90-min outpatient evaluation of 3 individuals with severe handicaps. During the initial analogue assessment, which focused on identifying maintaining contingencies for aggressive behavior, each participant displayed a substantially greater frequency of aggressive behavior during one condition than during any other. The contingency that produced the highest percentage of aggressive behavior was then presented for the occurrence of a specific alternative behavior (a mand). During this contingency reversal phase, each participant displayed a substantial reduction in aggressive behavior and a substantial increase in alternative behavior, thus providing a direct analysis of the equivalency of the contingency for maintaining either behavior.

Abstract
We evaluated the separate treatment components of a functional communication training program for 3 severely handicapped persons who each displayed different topographies of aberrant behavior. Following a functional analysis of maintaining conditions for inappropriate behavior (self-injury, stereotypy, aggression), each participant was trained to emit a communicative response that functioned to solicit reinforcement. For 2 participants, consequences (time-out or graduated guidance) for inappropriate behavior were also included. Treatment continued until the participants emitted the communicative response independently and no occurrences of inappropriate behavior were observed for at least two sessions. Following treatment, the separate contributions of the treatment components for communicative responding and for inappropriate behavior were evaluated with a reversal design. The results indicated that both sets of treatment components were necessary for maximal control over aberrant behavior. These results are discussed in relation to the efficiency, history, and control over reinforcement of both appropriate and inappropriate responses.

Abstract
We propose the use of a combined version of the alternating treatments and multiple baseline designs in situations in which a traditional baseline (no treatment) condition either does not provide an adequate contrast condition or is not feasible or practical due to clinical constraints. We refer to this design as a sequential alternating treatments design because two treatments are initially implemented in a random or counterbalanced fashion and are followed by a sequential change in one or both treatments across settings, subjects, or tasks. The effects of the independent variables are assessed first by analyzing the two series of data points representing the different treatments (relative effects) and then by assessing changes in one or both series, as application of the alternative treatment is introduced sequentially. The sequential application of treatment provides an analysis of control in the same manner as the multiple baseline design; the initial alternating treatments phase provides a contrast condition in much the same manner as a baseline condition. Applications of this design to the assessment of peer training and self-injurious behavior are described.
