Surgical management of compensatory sweating: A systematic review.

Endoscopic thoracic sympathectomy (ETS) surgery is a highly effective treatment of primary hyperhidrosis (PH) for the palms, face, axillae. Compensatory sweating (CS) is the most common and feared side effect of thoracic sympathectomy. CS is a phenomenon characterized by increased sweating in sites distal to the level of sympathectomy. Compensatory sweating is the main problem for which many patients give up surgery, losing the chance to solve their problem and accepting a poor quality of life. There are still no treatments that offer reliable solutions for compensatory sweating. The treatments proposed in the literature are scarce, with low case histories, and with uncertain results. Factors associated with CS are extension of manipulation of the sympathetic chain, level of sympathetic denervation, and body mass index. Therapeutic options include non surgical treatment and surgical treatment. Non surgical treatments include topical agents, botulinum toxin, systemic anticholinergics, iontophoresis. Surgical treatments include clip removal, extended sympathectomy and sympathetic chain reconstruction, although the efficacy is not well-established for all the methods. In this review we provide an overview of the treatments and outcomes described in the literature for the management of compensatory CS, with focus on surgical treatment.

Screening of latent tuberculosis infection among patients with diabetes mellitus from a high-burden area in Brazil.

Although several cohort studies have raised the important association between diabetes mellitus (DM) and latent tuberculosis infection (LTBI), evidences are limited and controversial. Furthermore, it is well documented that the poor glycemic control may exacerbate the risk for active TB. Thus, the monitoring of diabetic patients living in high-incidence areas for TB is an important concern in views of available diagnostic tests for LTBI. In this cross-sectional study, we estimate the association of DM and LTBI among diabetic patients classified as type-1 DM (T1D) or type-2 DM (T2D) living in Rio de Janeiro, RJ, Brazil - considered a high TB burden region of these country. Non-DM volunteers were included as endemic area healthy controls. All participants were screened for DM using glycosylated-hemoglobin (HbA1c) and for LTBI using the QuantiFERON-TB Gold in Tube (QFT-GIT). Demographic, socioeconomic, clinical and laboratorial data were also assessed. Among 553 included participants, 88 (15.9%) had QFT-GIT positive test, of which 18 (20.5%) were non-DM, 30 (34.1%) T1D and 40 (45.4%) T2D. After adjustments for potential baseline confounders, age, self-reported non-white skin color and an active TB case in the family were significantly associated with LTBI among the studied population by using a hierarchical multivariate logistic regression analysis. Additionally, we verified that T2D patients were able to produce significant increased interferon-gamma (IFN-γ) plasma levels in response to Mycobacterium tuberculosis-specific antigens, when compared to non-DM individuals. Altogether, our data showed an increased prevalence of LTBI among DM patients, albeit non-statistically significant, and point out to important independent factors associated with LTBI, which deserve attention in monitoring patients with DM. Moreover, QFT-GIT test seems to be a good tool to screening LTBI in this population, even in a high TB burden area.

Spanish Adaptation of the Pediatric Memorial Symptom Assessment Scale for Children, Teens, and Caregivers.

CONTEXT: There are no validated Spanish tools to assess symptom burden in pediatric cancer. The Pediatric Memorial Symptom Assessment Scale (Pediatric-MSAS) is an English valid multidimensional and comprehensive instrument. OBJECTIVES: To validate Pediatric-MSAS-Spanish (MSAS-Child, MSAS-Teen, and MSAS-Caregiver versions) in patients with cancer treated in two public hospitals in Buenos Aires, Argentina. METHODS: Cross-sectional study, classical psychometric theory. We recruited a convenience sample of 148 caregivers of children ≥ two years, 51 young children (seven to 12 years), and 48 adolescents (≥13 years). We assessed feasibility, comprehensibility, internal consistency, and convergent and known-groups validity. RESULTS: Pediatric-MSAS-Spanish was feasible, acceptable, and comprehensible. Reliability of MSAS-total and subscale scores was satisfactory (Cronbach alpha: 0.90, 0.89, 0.71, respectively, for caregiver, teen, and child MSAS-total score). MSAS-total caregiver, teen, and child scores met a priori criteria for convergent validity correlating with Pediatric Quality of Life Inventory total scores (Spearman correlation (rs) = -0.59, -0.66, and -0.32, respectively) and visual -analogue well-being scores (rs = -0.63, -0.46, and -0.4, respectively). Caregiver-teen correlation was strong for total (rs = 0.78) and physical (rs = 0.85) scores, and moderate for global distress index (rs = 0.64) and psychological (rs = 0.45) scores. MSAS-total caregiver-child correlation was moderate (rs = 0.30) and Kappa analysis showed poor agreement. All MSAS-Caregiver scores and MSAS-Teen total and physical scores differentiated inpatients/outpatients and patients on/off-treatment, while MSAS-Teen psychological and global distress index subscales or MSAS-Child scores did not. CONCLUSION: Pediatric-MSAS-Spanish is feasible and reliable for assessing symptom burden in children with cancer. Validity of MSAS-Caregiver and MSAS-Teen was largely supported. Further work on MSAS-Child is warranted.

Small is better: comparing the efficiency of two Surber samplers' sizes for biomonitoring programs in tropical headwater streams in the Amazon region.

This study aimed to compare the efficiency of two different sizes of the Surber sampler to assess benthic macroinvertebrates in headwater streams in two Amazonian regions. Two Surber samplers of different sizes were used, one measuring 20 × 20 cm and the other 30 × 30 cm, both with a 0.25-mm net. The number of replicates taken was 6 for the smaller sampler and 3 for the bigger one, maintaining approximately the same total sampled area. The study was carried out in 12 headwater streams with different environmental conditions. Biological metrics were calculated for each size at each site and compared within each stream health category. A two-way analysis of similarities test was performed to compare the community structure assessed by each method at each stream. A normalized sampling effort was used to quantify the number of samples required to correctly sample each site. The data did not show a significant difference between the two sizes regarding the taxonomic recruitment and the community structure sampled at each stream, but differences were found between the two sizes in dominance values and in Shannon index scores for the natural sites. Furthermore, the smaller Surber was able to assess 70% of the estimated richness in all sites, which suggests that it is better to assess benthic macroinvertebrates than the larger Surber. Moreover, the smaller Surber is easier to transport in the field, reducing the effort of the technician, and takes less time to sort the material collected with it, which can reduce the sample processing effort, therefore reducing the cost of the project.

Adaptación y validación de la escala para evaluación de síntomas MSAS (Memorial Symptom Assessment Scale) e niños con cáncer de 2 a 20 años / Adaptation and validation of the scale for evaluation of symptoms MSAS (Memorial Symptom Assessment Scale) and children with cancer from 2 to 20 years

INTRODUCCIÓN En la atención de niños con cáncer es importante contar con herramientas que permitan medir síntomas. La validación de herramientas constituye una prioridad para avanzar el conocimiento en esta población de pacientes. La escala MSAS es una herramienta multidimensional que valora múltiples síntomas, ampliamente utilizada en la literatura y que ya cuenta con una traducción al español para Argentina. OBJETIVOS Contribuir al proceso de validación de tres versiones de la escala MSAS en español para la Argentina (MSAS 7 a 12 años, MSAS-adolescentes, y MSAS-padres). MÉTODOS Estudio de corte transversal de dos fases, con una fase de validación lingüística inicial y una segunda fase de evaluación de comprensibilidad, aceptabilidad y testeo de validez de construcción. Se recolectó una muestra de 90 díadas, pacientes de 2 a 20 años con diagnóstico de cáncer y sus cuidadores, a los que se les administró la escala MSAS. Además de la escala se utilizaron el PedsQL 4.0, una pregunta de bienestar general y un cuestionario de evaluación de comprensibilidad y aceptabilidad. RESULTADOS Se reclutaron un total de 91 díadas. 60 niños mayores a 7 años y 91 cuidadores. La mediana de edad de los niños fue de 9 años (RIC 5.7-14.6). El 91% de los niños mayores a 7 años y el 90% de los cuidadores pudieron auto-administrarse los cuestionarios. La mediana de síntomas fue de 2 (RIC 1-4) para niños, 9 (RIC 6-13) para adolescentes y 6 (RIC 3-12) para cuidadores. Respecto a la comprensibilidad más del 60% de los niños reportó que entendió las preguntas y a un 50% no le molestaría responder el cuestionario una vez por semana. DISCUSIÓN La utilización de la escala MSAS es factible y comprensible y bien aceptada por los participantes del estudio, especialmente en los cuidadores. Se requieren investigaciones ulteriores para entender el funcionamiento de esta escala en los niños con cáncer

l-carnosine dipeptide overcomes acquired resistance to 5-fluorouracil in HT29 human colon cancer cells via downregulation of HIF1-alpha and induction of apoptosis.

Hypoxia-inducible factor (HIF-1α) protein is over-expressed in many human cancers and is a major cause of resistance to drugs. HIF-1α up-regulation decreases the effectiveness of several anticancer agents, including 5-fluorouracil (5-FU), because it induces the expression of drug efflux transporters, alters DNA repair mechanisms and modifies the balance between pro- and antiapoptotic factors. These findings suggest that inhibition of HIF-1α activity may sensitize cancer cells to cytotoxic drugs. We previously reported that l-carnosine reduces HIF-1α expression by inhibiting the proliferation of colon cancer cells. In the present study we investigated the effect of l-carnosine on HT29 colon cancer cells with acquired resistance to 5-FU. We found that l-carnosine reduces colon cancer cell viability, decreases HIF-1α and multi-drug resistant protein MDR1-pg expression, and induces apoptosis. Moreover, the l-carnosine/5-FU combination lowers the expression of some chemoresistance markers. The combination index evaluated in vitro on the HT29-5FU cell line by median drug effect analysis reveals a significant synergistic effect.

Oncolytic Adenovirus Loaded with L-carnosine as Novel Strategy to Enhance the Antitumor Activity.

Oncolytic viruses are able to specifically replicate, infect, and kill only cancer cells. Their combination with chemotherapeutic drugs has shown promising results due to the synergistic action of virus and drugs; the combinatorial therapy is considered a potential clinically relevant approach for cancer. In this study, we optimized a strategy to absorb peptides on the viral capsid, based on electrostatic interaction, and used this strategy to deliver an active antitumor drug. We used L-carnosine, a naturally occurring histidine dipeptide with a significant antiproliferative activity. An ad hoc modified, positively charged L-carnosine was combined with the capsid of an oncolytic adenovirus to generate an electrostatic virus-carnosine complex. This complex showed enhanced antitumor efficacy in vitro and in vivo in different tumor models. In HCT-116 colorectal and A549 lung cancer cell lines, the complex showed higher transduction ratio and infectious titer compared with an uncoated oncolytic adenovirus. The in vivo efficacy of the complex was tested in lung and colon cancer xenograft models, showing a significant reduction in tumor growth. Importantly, we investigated the molecular mechanisms underlying the effects of complex on tumor growth reduction. We found that complex induces apoptosis in both cell lines, by using two different mechanisms, enhancing viral replication and affecting the expression of Hsp27. Our system could be used in future studies also for delivery of other bioactive drugs. Mol Cancer Ther; 15(4); 651-60. ©2016 AACR.

Efeitos de um programa de ensino de leitura sobre a inteligibilidade da fala de crianças usuárias de implante coclear / Effects of a reading teaching program on the speech intelligibility of children using cochlear implant

Considerando a reabilitação da fala de crianças com deficiência auditiva e usuárias de implante coclear e evidências da possibilidade de transferência de controle de estímulos da leitura para a nomeação, este estudo teve como objetivo avaliar os efeitos de um programa de ensino de leitura de palavras simples sobre a qualidade da fala de duas crianças em testes de leitura de palavras e nomeação de figuras. O procedimento consistiu no ensino de relações condicionais baseadas em seleção de palavras impressas e de composição após a palavra ditada. A nomeação de figuras foi avaliada em um delineamento de linhas de base múltipla. Os resultados mostram melhora na qualidade da fala, se comparados à linha de base, tanto frente a palavras quanto frente a figuras. Futuros estudos, com maior número de participantes e outros delineamentos devem verificar benefícios de programas de ensino ao processo de reabilitação dessa população.

Considering the speech rehabilitation in children with hearing impairment and cochlear implant and the evidence of possible stimuli control transference of reading to naming, the objective of the present study was to evaluate the effects of a teaching program for reading simple words on the speech intelligibility of two children in tests of reading words and naming pictures. The procedure consisted of teaching conditional relations based on a selection of printed words and word composition after word dictation. Picture naming was assessed in a multibaseline design. Data showed improvement in the quality of responses when compared to baseline, both in front of words and pictures. Future studies with higher number of participants and other experimental designs may verify the benefits of teaching programs to the rehabilitation process of this population.

Usando o paradigma de equivalência para aumentar a correspondência na fala de crianças com implante coclear na nomeação de figuras e na leitura / Using the equivalence paradigm to increase the correspondence of vocalizations by children with cochlear implant in picture naming and reading

Este estudo investigou os efeitos da formação de relações de equivalência entre palavras faladas, palavras impressas e figuras sobre a correspondência na fala de crianças com implante coclear em tarefas de nomeação de figuras e de leitura oral. Antes do estudo as crianças pronunciavam melhor as palavras quando liam do que quando nomeavam as figuras. Foram ensinados dois conjuntos de três relações entre palavras ditadas e as figuras correspondentes, entre as mesmas palavras ditadas e palavras impressas e entre sílabas ditadas e impressas. Sondas periódicas de nomeação das seis figuras e de leitura das palavras impressas, planejadas de acordo com um delineamento de linha de base múltipla entre conjuntos, eram realizadas antes e depois do ensino de cada tipo de relação condicional e do teste de formação de classes de equivalência de cada conjunto. As vocalizações na nomeação de figuras melhoraram progressivamente para cinco dos seis participantes ao longo do ensino do Conjunto 1 e para todos os participantes depois do ensino do Conjunto 2. Na leitura, as vocalizações também ficaram mais precisas. Os resultados estendem descobertas prévias sobre o potencial de procedimentos baseados no paradigma de equivalência de estímulos para a reabilitação da fala e da compreensão auditiva de indivíduos com implante coclear. (AU)

The present study investigated the effects of strengthening equivalence relations between spoken words, printed words, and pictures to improve the correspondence between vocalizations in picture naming and in reading tasks in children with cochlear implant. Before the study, the children pronounced words better while reading than while naming pictures. The procedure taught two sets of three relations between dictated words and pictures, between the same dictated words and printed words, and between dictated and printed syllables. Periodic probes evaluated the experimental effects according to a multiple baseline design between stimulus sets. Picture naming and reading of all six words were probed before and after teaching each type of relationship and testing for class formation for each stimulus set. Picture naming progressively improved for five of six participants across teaching and probes with Stimulus Set 1, and for all participants across Stimulus Set 2. Reading scores, initially high, also reached perfect or near perfect accuracy. The results extend previous findings on the potential of procedures based on the stimulus equivalence paradigm for improving speech and listening comprehension of children with cochlear implant.

Munich Music Questionnaire: adaptation into Brazilian Portuguese and application in cochlear implant users.

PURPOSE: To translate the Munich Music Questionnaire (MUMU) to Brazilian Portuguese, to adapt it culturally, and to describe the results obtained among adult users of cochlear implant (CI). METHODS: We translated the questionnaire to Brazilian Portuguese, reviewed the grammatical and idiomatic equivalences (back-translation), and adapted it from a linguistic and cultural perspective. The resulting version of this process was applied among adult CI users through direct interviews. RESULTS: The Brazilian Portuguese version of MUMU was applied to 19 adult CI users with postlingual hearing loss, who had been users of the device for at least one year. The answers to the questionnaire were analyzed by distribution of frequency and percentage of occurrence in each question. The results showed a decrease in the frequency of CI users that listen to music, comparing the period before hearing loss and after the CI. Regarding the role that music played in the life of each participant, the responses did not score change, so the music remained being an important factor in the life of the evaluated subjects, even after the CI. CONCLUSION: The subjective evaluation tool MUMU was translated and culturally adapted to the population studied. In Brazilian Portuguese, it was called Questionário de Música de Munique. The study showed its applicability in the daily monitoring of CI users, thus providing a profile of the activities related to music in everyday life.

An initial study of voice characteristics of children using two different sound coding strategies in comparison to normal hearing children.

OBJECTIVE: To compare some perceptual and acoustic characteristics of the voices of children who use the advanced combination encoder (ACE) or fine structure processing (FSP) speech coding strategies, and to investigate whether these characteristics differ from children with normal hearing. DESIGN: Acoustic analysis of the sustained vowel /a/ was performed using the multi-dimensional voice program (MDVP). Analyses of sequential and spontaneous speech were performed using the real time pitch. Perceptual analyses of these samples were performed using visual-analogic scales of pre-selected parameters. STUDY SAMPLE: Seventy-six children from three years to five years and 11 months of age participated. Twenty-eight were users of ACE, 23 were users of FSP, and 25 were children with normal hearing. RESULTS: Although both groups with CI presented with some deviated vocal features, the users of ACE presented with voice quality more like children with normal hearing than the users of FSP. CONCLUSIONS: Sound processing of ACE appeared to provide better conditions for auditory monitoring of the voice, and consequently, for better control of the voice production. However, these findings need to be further investigated due to the lack of comparative studies published to understand exactly which attributes of sound processing are responsible for differences in performance.

A Photolithographic Approach to Polymeric Microneedles Array Fabrication.

In this work, two procedures for fabrication of polymeric microneedles based on direct photolithography, without any etching or molding process, are reported. Polyethylene glycol (average molecular weight 250 Da), casted into a silicone vessel and exposed to ultraviolet light (365 nm) through a mask, cross-links when added by a commercial photocatalyzer. By changing the position of the microneedles support with respect to the vessel, different shapes and lengths can be achieved. Microneedles from a hundred microns up to two millimeters have been obtained just tuning the radiation dose, by changing the exposure time (5-15 s) and/or the power density (9-18 mW/cm²) during photolithography. Different microneedle shapes, such as cylindrical, conic or lancet-like, for specific applications such as micro-indentation or drug delivery, are demonstrated.

Identification of Serologic Markers for School-Aged Children With Congenital Rubella Syndrome.

BACKGROUND: Congenital rubella syndrome (CRS) case identification is challenging in older children since laboratory markers of congenital rubella virus (RUBV) infection do not persist beyond age 12 months. METHODS: We enrolled children with CRS born between 1998 and 2003 and compared their immune responses to RUBV with those of their mothers and a group of similarly aged children without CRS. Demographic data and sera were collected. Sera were tested for anti-RUBV immunoglobulin G (IgG), IgG avidity, and IgG response to the 3 viral structural proteins (E1, E2, and C), reflected by immunoblot fluorescent signals. RESULTS: We enrolled 32 children with CRS, 31 mothers, and 62 children without CRS. The immunoblot signal strength to C and the ratio of the C signal to the RUBV-specific IgG concentration were higher (P < .029 for both) and the ratio of the E1 signal to the RUBV-specific IgG concentration lower (P = .001) in children with CRS, compared with their mothers. Compared with children without CRS, children with CRS had more RUBV-specific IgG (P < .001), a stronger C signal (P < .001), and a stronger E2 signal (P ≤ .001). Two classification rules for children with versus children without CRS gave 100% specificity with >65% sensitivity. CONCLUSIONS: This study was the first to establish classification rules for identifying CRS in school-aged children, using laboratory biomarkers. These biomarkers should allow improved burden of disease estimates and monitoring of CRS control programs.
