Pathergy-like reaction induced by laser hair removal in a patient with Behçet disease.

Behçet disease (BD) is a rare systemic vasculitis of unknown etiology, primarily characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Pathergy test positivity is a nonspecific inflammatory response of the skin to trauma and supports the diagnosis. Recently, new inducers of pathergy reactions have been identified, for example, the placement of dental braces and laser hair removal. Our clinical case highlights the importance of thinking about this potential pathergy inducer in BD patients, to improve their quality of life and avoid complications.

Low-level laser therapy to treat fibromyalgia.

Several clinical treatments have been proposed to manage symptoms of fibromyalgia. Low-level laser therapy (LLLT) may be a useful tool to treat this dysfunction. The aim of this study was to evaluate the effects of LLLT in patients with fibromyalgia. A placebo-controlled, randomized clinical trial was carried out with 20 patients divided randomly into either an LLLT group (n = 10) or a placebo group (n = 10). The LLLT group was treated with a GaAlAs laser (670 nm, 4 J/cm(2) on 18 tender points) three times a week over 4 weeks. Before and after treatment, patients were evaluated with the Fibromyalgia Impact Questionnaire (FIQ), McGill Pain Questionnaire, and visual analog scale (VAS). Data from the FIQ and McGill questionnaire for the treated and control groups were analyzed by paired t tests, and Wilcoxon tests were used to analyze data from the VAS. After LLLT or sham treatment, the number of tender points was significantly reduced in both groups (LLLT, p < 0.0001; placebo, p = 0.0001). However, all other fibromyalgia symptoms showed significant improvements after LLLT compared to placebo (FIQ, p = 0.0003; McGill, p = 0.0078; and VAS, p = 0.0020). LLLT provided relief from fibromyalgia symptoms in patients and should be further investigated as a therapeutic tool for management in fibromyalgia.

Tic disorders and premonitory urges: validation of the Spanish-language version of the Premonitory Urge for Tics Scale in children and adolescents.

INTRODUCTION: Most people with persistent tics report an unpleasant sensation (premonitory urge) before the tic. In recent years, interest in these sensory phenomena has increased due to their important role in behavioural therapy. However, instruments for assessing these sensations remain scarce. Among the available instruments, the Premonitory Urge for Tics Scale (PUTS) is the most widely used. METHODS: We examined the psychometric properties and factor structure of the Spanish-language version of the PUTS in a sample of 72 children and adolescents with Tourette syndrome or persistent tic disorders. We analysed data from the total sample and by age group (children up to 10 years old and children/adolescents over 10). RESULTS: The PUTS presented good internal consistency and moderate correlations between items on the scale (except for item 1). Divergent validity was good, test-retest reliability was adequate, and a bifactorial structure was identified (one dimension related to mental phenomena reported in obsessive-compulsive disorder, and another related to the quality and frequency of premonitory urges). These results were replicated in both age groups, with lower divergent validity and test-retest reliability in the younger group. CONCLUSIONS: The Spanish-language version of the PUTS is a valid, reliable tool for assessing premonitory urges in both children and adolescents, especially after the age of 10.

The impact of photodynamic therapy on the viability of Streptococcus mutans in a planktonic culture.

OBJECTIVE: This study investigated the effect of photodynamic therapy (PDT) with toluidine blue O (TBO) and a light-emitting diode (LED) on the viability of Streptococcus mutans cells in a planktonic culture. BACKGROUND DATA: Growth of Streptococcus mutans is the first step in the development of tooth decay. The use of light and dyes promotes cellular death in a noninvasive way, reducing treatment time. METHODS: The LED used in this study had output power of 116 mW, its energy was 21 J, and the fluency was 2.18 J/cm(2). Samples were prepared and divided into five groups: (1) control group (-); (2) control group (+); (3) TBO; (4) LED; and (5) LED + TBO. RESULTS: One hundred percent of the bacteria were killed following irradiation with LED and TBO. The biofilm that formed on the glass surfaces was analyzed by SEM and colony count. CONCLUSIONS: It was demonstrated that PDT was efficient at killing microorganisms and preventing the formation of biofilms.

Collaborative monitoring of chlorine flavours in drinking water.

Sensory data have always been used by concerned citizens to evaluate environmental variables within volunteer monitoring initiatives. The work presented in this paper intends to explore the possibility of using human sensory data as a source of information to monitor environmental quality variables within a public participation context. A case study that uses untrained citizens to monitor chlorine flavour of tap water is presented. Two collaborative monitoring tests were developed: (1) the one-sample one-trial test and (2) the Chlorine@Home test. The tests intended to address the participatory context required by collaborative monitoring initiatives. The development of the collaborative tests was supported by two tests that were designed for a laboratory context and explored sensory methodologies. The sensory tests implemented were: (1) the paired comparison test, (2) the forced-choice triangle test (ASTM Method E679-04). The collaborative experiments showed that the ability to detect chlorine flavours on a participatory context was independent on chlorine concentrations. The use of sensors by citizens may be a way to increase the credibility of the information. Nevertheless, this case study suggested that more research should be carried out to explore ways to involve citizens while increasing data reliability.

Transfer of nutrients and labile metals from the continent to the sea by a small Mediterranean river.

The contribution of small watersheds to coastal pollution in Mediterranean areas is still poorly known, and presents great variations along an hydrological year. This work deals with the characterization and quantification of Al, Fe, Zn, Cu, Pb, Si, NO(3)(-) and organic carbon transported from the continent to the sea by a small coastal river in the French Mediterranean area. Transported species were characterized both during rainy and dry periods. During non-rainy periods (base-flow), waters showed a low content of contaminants, whereas during heavy rain events, following dry periods, some metals and organic carbon reached concentrations that could affect biological populations. These contaminants were mainly found in the particulate fraction, originating from the runoff of surface waters, which represents the main process of pollution in urban areas.

Microcalcificaciones en ausencia de nódulo tiroideo identificable por ecografía y su asociación a cáncer de tiroides: a propósito de un caso / Microcalcifications in the absence of identifiable thyroid nodule on sonography and its association with thyroid carcinoma: a case report

La ecografía tiroidea es la principal herramienta diagnóstica en el manejo de los nódulos tiroideos, siendo la presencia de microcalcificaciones un signo de malignidad. Sin embargo, existen escasas publicaciones acerca de la presencia de microcalcificaciones en ausencia de nódulo identificable y su asociación con cáncer de tiroides. Presentamos un caso de una mujer de 26 años, que, tras hallazgo incidental de bocio, se describe en ecografía un tiroides con alteración difusa de su ecogenicidad e imágenes compatibles con microcalcificaciones sin claro nódulo definido en su polo inferior. Tras realización de punción aspiración con aguja fina de la lesión con resultado Bethesda categoría 5, se decide realizar tiroidectomía total, presentando estudio histológico con diagnóstico de carcinoma papilar de tiroides variante clásica con metástasis ganglionares p(T1bN1a). Tras una revisión sistemática, los estudios hasta hoy publicados sugieren que la presencia de microcalcificaciones aisladas sin nódulo identificable debe considerarse un importante factor de riesgo de cáncer de tiroides, especialmente en gente joven, y en aquellas asentadas sobre una tiroiditis de Hashimoto. Por ende, resulta imperativo mantener una alta sospecha ante el hallazgo de este tipo de lesiones, recomendando una valoración exhaustiva de las mismas con la realización de una punción aspiración con aguja fina a todas las lesiones con dichas características.

Thyroid ultrasound is the main diagnostic tool in the management of thyroid nodules, with the presence of microcalcifications being a sign of malignancy. However, there are few publications about the presence of microcalcifications in the absence of an identifiable nodule and its association with thyroid cancer. We present a case of a 26-year-old woman who, after an incidental finding of goiter, a thyroid with diffuse echogenicity alteration and images compatible with microcalcifications without a clear nodule defined in the lower pole of the lobe is described on the ultrasound. After performing a fine needle aspiration of the lesion resulting in a Bethesda category 5, a total thyroidectomy was performed, presenting in the histological study a diagnosis of a classic variant of a papillary thyroid carcinoma with lymph node metastases p (T1bN1a). After a systematic review, the studies previously published suggest that the presence of isolated microcalcifications without an identifiable nodule should be considered an important risk factor for thyroid cancer, especially in young people, and in those with a concomitant Hashimoto's thyroiditis. Therefore, it is imperative to maintain a high suspicion of the discovery of this type of lesion, recommending an exhaustive assessment of them with the performance of a fine needle aspiration to all lesions with these features.

Preliminary pharmacologic evaluation of crude whole plant extracts of Elephantopus scaber. Part I: In vivo studies.

Elephantopus scaber has been used in Brazil as a traditional remedy to cause diuresis, antipyresis and to eliminate bladder stones. In the current study, aqueous and hydroalcoholic extracts of whole plants were tested for acute toxicity, analgesic, antipyretic, antiinflammatory, cardiovascular, diuretic and constipating activities. Both extracts (0.3-6 g/kg i.p.) induced writhing, loss of muscle tone, ataxia, prostration and death in mice. No analgesic effects of these extracts were detected using mouse hot-plate and acetic acid-induced writhing tests. Both extracts failed to modify diuresis or carrageenan-induced rat paw edema. In contrast, given intraperitoneally, both reduced brewer's yeast-induced hyperthermia in rats, but when given orally did not affect it. Moreover, the aqueous extract decreased the intestinal transit time in mice while the hydroalcoholic extract increased it. Finally, these extracts, given intravenously, reduced blood pressure and heart rate in rats; these effects could be blocked by atropine but not by co-administration of pyrilamine and cimetidine.

Behavioral treatment of a case of psychogenic urinary retention.

The case involved a thirteen-year-old girl with a history of different urological disorders who since the age of four showed several rituals associated with micturition as well as progressively intense urinary retention. Micturition occupied 2 to 12 hours a day. Treatment consists of systematic desensitization through imagery and in vivo together with progressive response prevention of ritualized behaviours. Cognitive therapy and parent counselling is also used. Normality is attained after 7 weeks treatment and maintained at 18 months follow-up. Psychiatric diagnosis is simple phobia to micturition.

Base flow and stormwater net fluxes of carbon and trace metals to the Mediterranean sea by an urbanized small river.

Base flow and storm flow events from a small, urbanized Mediterranean river located in the South of France were studied to evaluate net fluxes from the continent to the coastal sea water. Considered variables were: pH, conductivity, redox potential, temperature, dissolved O(2), SPM (Suspended Particulate Matter), Cl(-), NO(3)(-), SO(4)(2-), Na(+), K(+), Mg(2+), Ca(2+), DOC (Dissolved Organic Carbon), Cu, Zn, Cd and Pb in the dissolved fraction and POC (Particulate Organic Carbon), Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb in the particulate fraction. If rainfall intensity and antecedent rainfall history were sufficient to explain many observed variations, the patterns of particles and solutes transport greatly varied from one storm event to another. SPM, POC, particulate Cu, Zn, Cd and Pb had similar behavior characterized by an immediate increase at the beginning of the storm flow and the highest values at the first high discharge peak. Among dissolved species, Cl(-), SO(4)(2-), Na(+), Ca(2+) and Mg(2+) had a behavior very similar one to the other. They exhibited high concentrations and enrichment factors at the beginning of the storm flow, due to fast leaching of highly labile species. Their concentrations decreased during posterior discharge peaks but positive enrichment factors indicated permanent sources for these ions. DOC, K(+) and NO(3)(-) had different behaviors which indicated sources positively correlated with rainfall intensity. A 3D-fluorescence study showed that the humified organic matter contribution to DOC increased during storm flow. Relationships between DOC and dissolved Cu and Pb indicated differences in organic-matter binding properties between dry and humid periods. Storm flow were responsible for more than 90% of the annual output to the sea of SPM, POC and particulate Cu, Zn, Cd and Pb and more than 70% for dissolved Pb, Cd, NO(3)(-) and DOC. For the other dissolved species, outputs were balanced between base flow and storm flow. Contrary to what was observed in large rivers, organic carbon was mainly transported in the POC fraction. The average specific fluxes of Cu and Pb to the sea were 3.8 and 3.4 kg km(-2) y(-1), respectively, of the same order of magnitude than specific fluxes of other North-Mediterranean rivers, but outputs were more intense during shorter durations. The extrapolation of the Eygoutier River data to the Mediterranean non-desert coastline showed that the order of magnitude of Cu and Pb annually brought to the sea by the whole of small anthropized coastal rivers can be similar to the annual input by the Rhône or the Po River.

Sirenomelia and situs inversus: case report and review of the literature.

We report a case of sirenomelia of the symelia dipus type which is associated with complete situs inversus. Sirenomelia is difficult to diagnose prenatally because of a frequently associated oligohydramnios. Symelia dipus type adds to the difficulty of the diagnosis, since the bones of the thighs and legs are fully formed. In fact, a close examination of the cases of sirenomelia previously reported in the literature shows that a prenatal diagnosis was achieved only when the oligohydramnios was no more than moderate and/or the associated malformation was of apus or unipus type. We propose a systematic amnioinfusion when one suspects symelia unipus type. Finally, the pathogenesis of sirenomelia is discussed, as the presence of a complete situs inversus in the case reported here could illuminate the debate concerning the origin of the malformation.

[A retrospective study of 83 patients hospitalized for a jaundice syndrome in the Surgical Clinic of Timisoara Municipal Hospital]. / Studiu retrospectiv privind 83 de pacienti internati pentru un sindrom icteric în clinica de chirurgie a Spitalului municipal Timisoara.

This is a retrospective study done on 83 patients admitted to surgical department of Timisoara Emergency Hospital in the period between 01/01/1992 and 31/03/1995; 47 patients were males, 36 females with mean age 56.1 years. All patients suffered from jaundice mainly conjugated hyperbilirubinemia. The causes of jaundice were: malignant tumours in 19 (22.9%), chronic diffuse parenchymatous liver disease in 24, stone common bile duct 22, benign biliary strictures and papillary stenosis in 6, extrinsic biliary compression and inflammation in 12. Surgery was done in 47 patients and medical treatment in 36 patients. During hospitalization, complications occurred in 19 patients. The condition of patients at discharge was considered: cured in 30, improved in 38, stationary in 2 and deteriorated in 12. Mortality occurred in one patient.

A clinical and phenomenological study of 185 Spanish adolescents with anorexia nervosa.

The objectives of the present study were the following to determine the socio-familial, academic and interpersonal characteristics specific to anorexia nervosa (AN); to study comorbidity in patients with anorexia and morbidity in their parents; and to ascertain whether patients with anorexia nervosa in Spain are similar to those in other countries. The research team revised the clinical records of 185 Spanish adolescents with AN (aged 11-18 years). The results were compared with those obtained from a group of 185 psychiatric patients without AN matched by sex, age, time of consultation and centre. No significant differences were found with regard to broken home, birth order or parent-patient conflict. The parents of patients with anorexia have a higher standard of education and develop more affective disorders. When compared with other patients, the individuals with anorexia nervosa perform much better academically but are more socially withdrawn. Males with anorexia nervosa perform worse academically than females and have more anxiety diagnoses. Patients with anorexia have a high comorbidity for affective and obsessive-compulsive disorders. Sufferers from anorexia nervosa in Spain are clinically analogous to patients with anorexia in other countries. The two characteristics specific to these patients are a high standard of academic performance and an intense degree of social withdrawal, although there are certain factors common to other pathologies relating to adolescence.

Análise clínica do efeito da fotobiomodulação laser (GaAs - 904 nm) sobre a disfunção temporomandibular / Clinical analysis of the effect of laser photobiomodulation (GaAs - 904 nm) on temporomandibular joint dysfunction

INTRODUÇÃO: Nos últimos anos, tem sido notado grande interesse no estudo de novas modalidades para o tratamento das disfunções temporomandibulares (DTM). A dor descrita como dor facial, cefaléia ou dor de ouvido, comumente exacerbada pela função da mandíbula, é, em geral, a principal queixa do paciente. A fotobiomodulação laser vem sendo utilizada no tratamento da dor em DTM. OBJETIVO: O objetivo deste estudo foi verificar o nível de dor de pacientes com DTM tratados com fotobiomodulação laser. MATERIAIS E MÉTODOS: Foram estudados 18 pacientes do sexo feminino, com idade média de 27 anos (± 7), com diagnóstico de DTM, os quais foram separados aleatoriamente em dois grupos: Placebo (Controle) e Tratado. O Grupo Tratado (n= 10) recebeu atendimento duas vezes por semana, por quatro semanas consecutivas (totalizando oito aplicações). Utilizou-se o laser de GaAs (904 nm), 6 J/cm², 0,38 mW/cm², área do feixe de 0,039 cm², com modo de emissão contínua. Realizou-se a aplicação do laser em quatro pontos pré-auriculares e um em meato acústico externo. O Grupo Placebo (n= 8) foi manipulado como o tratado, porém com o laser desligado. Para análise do nível de dor dos pacientes, empregou-se a Escala Visual Analógica (EVA) de dor, antes e após a terapia. Para a análise dos dados, empregou-se o teste t de Student, com nível de significância de 5 por cento (p< 0,05). RESULTADOS: Observou-se redução significativa (p< 0,05) do nível de dor do Grupo Tratado. CONCLUSÕES: A fotobiomodulação laser (GaAs, 904 nm) testada demonstrou ser positiva para o alívio da sintomatologia dolorosa em pacientes com DTM.

INTRODUCTION: Over the last few years, there has been great interest in studying new methods for treating temporomandibular joint dysfunction (TMD). Pain, described as facial pain, headache or earache, usually exacerbated by jaw use, is generally the patients' main complaint. Laser photobiomodulation has been used for treating pain in cases of TMD. OBJECTIVE: The aim of this study was to investigate the pain levels in TMD patients treated with laser photobiomodulation. MATERIAL AND METHODS: Eighteen female patients of mean age was 27 years (± 7), with a diagnosis of TMD, were studied. They were randomly divided into two groups: Placebo (Control) and Experimental Groups. The Experimental Group (n= 10) received treatment twice a week, for four consecutive weeks (totaling eight applications). The GaAs laser (904 nm) was used, with 6 J/cm², 0.38 mW/cm², beam area of 0.039cm² and continuous emission mode. The laser was applied at four pre-auricular points and one in the external auditory meatus. The Placebo Group (n= 8) was manipulated in the same way as the treated group, but with the laser switched off. To analyze the patients' pain levels, a visual analog scale (VAS) was used, before and after the therapy. To analyze the data, Student's t test was used, with a significance level of 5 percent (p< 0.05). RESULTS: A significant reduction (p< 0.05) in the pain level was observed in the Treated Group. CONCLUSIONS: The tested laser photobiomodulation (GaAs, 904 nm) demonstrated positive results regarding the relief of painful symptoms in patients with TMD.

CONTEXTUALIZAÇÃO: As lesões nervosas periféricas podem comprometer atividades diárias de um indivíduo e resultam em perda da sensibilidade e motricidade do território inervado. OBJETIVO: Com o intuito de acelerar os processos regenerativos, objetivou-se analisar a influência da aplicação do laser de arsenieto de gálio e alumínio (AsGaAl, 660Nm) sobre a recuperação funcional do nervo ciático de ratos. MATERIAIS E MÉTODOS: O nervo ciático de 12 ratos Wistar foi submetido à lesão por neurotmese e anastomose epineural e divididos em dois grupos: controle e laserterapia. Após a lesão, utilizou-se o laser de GaAlAs, 660Nm, 4J/cm², 26,3mW, feixe de 0,63cm², em três pontos eqüidistantes sobre a lesão, por 20 dias. As impressões das pegadas dos animais foram obtidas antes e após (sete, 14 e 21 dias pós-operatórios) o procedimento cirúrgico e calculou-se o índice funcional do ciático (IFC). RESULTADOS: A comparação do IFC não resultou em diferença significante (p>0,05) entre os grupos. CONCLUSÕES: Conclui-se que os parâmetros e métodos empregados na laserterapia demonstram resultados nulos sobre o IFC no período avaliado.

CONTEXT: Peripheral nerve injuries result in sensory and motor losses in the innervated area and can hinder individuals' daily activities. Objective: The objective was to analyze the influence of applying gallium-aluminum-arsenide (GaAlAs) laser (660Nm) on the functional recovery of the sciatic nerve in rats. METHODS: The sciatic nerve of 12 Wistar rats was subjected to injury consisting of neurotmesis and epineural anastomosis. The rats were divided into two groups: control and laser therapy. After the injury, a GaAlAs laser was used (660Nm, 4J/cm², 26.3mW and 0.63cm² beam) at three equidistant points on the injury, for 20 days. Footprint impressions were obtained from the animals before and seven, 14 and 21 days after the surgical procedure and the sciatic functional index (SFI) was calculated. RESULTS: Comparison of the SFI did not show any significant difference (p>0.05) between the two groups. CONCLUSIONS: The parameters and methods used for the laser therapy did not produce any effect on the SFI over the period evaluated.
