[Rhinopoiesis after traumatic total amputation in childhood in an 11-year-old child]. / Rhinopoïese après amputation traumatique totale dans l'enfance chez un enfant de 11 ans.

Fortunately, traumatic total amputations of the nose are rare, especially in children. Their reconstructions generally require several operative steps, most often associating cartilaginous grafts (rib and/or concha), a free radial antebrachial flap for mucosal reconstruction and a frontal flap for the skin covering. These are therefore long and complex procedures requiring a trained surgical team and maximum patient adherence to their treatment plan. The clinical case described is that of an 11-year-old child presenting a sub-total amputation of the nose and having undergone reconstruction with skin expansion of the frontal flap due to a horizontal frontal scar of unknown origin and a particularly low hair implantation.

Impact of markers of endothelial injury and hypercoagulability on systemic lupus erythematosus.

We have explored the relationship between possible hemostatic changes and clinical manifestation of the systemic lupus erythematosus (SLE) as a function of greater or lesser disease activity according to Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) criteria. Endothelial injury and hypercoagulability were investigated in patients with SLE by measuring thrombomodulin (TM), D-dimer (DDi) and thrombin generation (TG) potential. A total of 90 participants were distributed into three groups: 1) women with SLE presenting with low disease activity (laSLE) (SLEDAI-2K ≤ 4), 2) women with SLE presenting with moderate to high disease activity (mhaSLE) (SLEDAI-2K > 4), and 3) a control group comprising healthy women. Levels of TM and DDi were higher both in the laSLE and mhaSLE groups compared to controls and in mhaSLE compared to the laSLE group. With respect to TG assay, lagtime and endogen thrombin potential, low concentrations of tissue factor provided the best results for discrimination among groups. Analysis of these data allow us to conclude that TM, DDi and TG are potentially useful markers for discriminating patients with very active from those with lower active disease. Higher SLE activity may cause endothelial injury, resulting in higher TG and consequently a hypercoagulability state underlying the picture of thrombosis common in this inflammatory disease.

Diagnostic criteria in Pai syndrome: results of a case series and a literature review.

Pai syndrome was originally described as the association of a midline cleft lip, midline facial polyps, and lipoma of the central nervous system. However, only a few patients present with the full triad, and most exhibit a wide spectrum of phenotypic variability. The aim of this study was to phenotypically delineate Pai syndrome and to propose new criteria to facilitate a clinical diagnosis in the future. The study cohort consisted of seven case patients and an additional 60 cases diagnosed with Pai syndrome identified in a literature review. Only 23 of 67 patients presented the full triad as historically described by Pai et al. (1987). A congenital facial midline skin mass was always encountered, particularly affecting the nasal structures (60/67). A midline facial cleft was reported in 45 of 67 patients and a pericallosal lipoma in 42 of 67 patients. The proposed definition of Pai syndrome is the association of (1) a congenital nasal and/or mediofrontal skin mass and/or a mid-anterior alveolar process polyp as a mandatory criterion, and at least one of the following criteria: (2) midline cleft lip and/or midline alveolar cleft, and/or (3) a pericallosal lipoma or interhemispheric lipoma in the case of corpus callosum dysgenesis.

Brain ameloblastoma: metastasis or local extension case report and physipathological reflexion.

BACKGROUND: Ameloblastoma is a rare benign odontogenic tumor with a metastasis rate estimated at 2% of cases, mainly involving the lung (80%) and lymph nodes (20%). METHODS: We hereby present the case of a 26 year old patient with a history of locally recurrent mandibular ameloblastoma who developed a temporal intracranial ameloblastoma tumor requiring a collaborative neurosurgical and maxillo-facial radical surgical approach. CONCLUSION: Although ameloblastomas are histologically benign, the temporal topography questions the dissemination pathophysiology of the tumor (metastasis or local extension through temporal muscle fibers), mainly relevant in cases of multiple recurrences.

Speech evaluation after intravelar veloplasty. How to use Borel-Maisonny classification in the international literature?

OBJECTIVE: Comparing functional outcomes after velar repair appeared to be difficult because of the absence of international standardized scale. Moreover most of the studies evaluating speech after cleft surgery present multiple biases. The aim of our study was to assess speech outcomes in a homogeneous group of patients, and to define an equivalence table between different speech scales. MATERIALS AND METHODS: Patients with isolated cleft lip and palate (CLP), operated in our unit by the same senior surgeon were included. All patient were operated according to the same protocol (cheilo-rhinoplasty and intravelar veloplasty at 6 months, followed by a direct closure of the hard palate at 15 months). Speech evaluation was performed after 3 year-old and before the alveolar cleft repair. Borel-Maisonny scale and nasometry were used for speech evaluation. RESULTS: Twenty-four patients were included: 17 unilateral CLP and 7 bilateral CLP. According to the Borel-Maisonny classifications, 82.5% were ranged phonation 1, 1-2 or 2b. Nasometry were normal in almost 60% of cases. CONCLUSIONS: This study showed the efficiency of our protocol, and intravelar veloplasty. Moreover we proposed an equivalence table for speech evaluation scale.

Pincer nail in a lupus patient.

Pincer nail is a transverse overcurvature of the nail plate that may appear in association with a variable number of diseases. We present a case report of a 28-year-old woman with pincer nail deformity associated with systemic lupus erythematosus. A renal biopsy confirmed class V lupus nephritis and treatment had included systemic steroids and cyclophosphamide. After 6 months there was a marked improvement of nail deformities.

Rating of perceived exertion as a tool for prescribing and self regulating interval training: a pilot study.

The aim of the present study was to analyse the usefulness of the 6-20 rating of perceived exertion (RPE) scale for prescribing and self-regulating high-intensity interval training (HIT) in young individuals. Eight healthy young subjects (age = 27.5±6.7 years) performed maximal graded exercise testing to determine their maximal and reserve heart rate (HR). Subjects then performed two HIT sessions (20 min on a treadmill) prescribed and regulated by their HR (HR: 1 min at 50% alternated with 1 min at 85% of reserve HR) or RPE (RPE: 1 minute at the 9-11 level [very light-fairly light] alternated with 1 minute at the 15-17 level [hard-very hard]) in random order. HR response and walking/running speed during the 20 min of exercise were compared between sessions. No significant difference between sessions was observed in HR during low- (HR: 135±15 bpm; RPE: 138±20 bpm) and high-intensity intervals (HR: 168±15 bpm; RPE: 170±18 bpm). Walking/running speed during low- (HR: 5.7±1.2 km · h(-1); RPE: 5.7±1.3 km · h(-1)) and high-intensity intervals (HR: 7.8±1.9 km · h(-1); RPE: 8.2±1.7 km · h(-1)) was also not different between sessions. No significant differences were observed in HR response and walking/running speed between HIT sessions prescribed and regulated by HR or RPE. This finding suggests that the 6-20 RPE scale may be a useful tool for prescribing and self-regulating HIT in young subjects.

Frequency and socio-psychological impact of taunting in school-age patients with cleft lip-palate surgical repair.

OBJECTIVES: Cleft lip-palate (CLP) is a "social" pathology because of its impact on the child's facial appearance and speech. School is the first place where children are confronted to others and when they start socializing. Taunting and bullying are common and their psychological impact remains hard to assess. The aim of this study was to evaluate the importance of taunting in school and its impact in CLP patients who had surgical repair. METHODS: We conducted a multicenter prospective study where we consecutively included patients ≥ 12 years who had CLP repair. During a multidisciplinary consultation they were asked to complete a questionnaire (3 parts: surgical outcomes, taunting and its impact, socio-economic status) previously approved by our psychologists. RESULTS: 55 patients were included (37 B, 18 G) (mean age 15.5 years): 11 CL, 13 CP and 31 CLP. 69% of patients reported having suffered from taunting and peer victimization in school. In 84% of the cases, taunting was linked to the CLP defect itself. The teasing started in primary school to reach a peak of aggressiveness in middle school. 42% of patients reported that bullying occurred at least once a day (16/38). Regarding the psychological impact of taunting, 50% of patients reported sadness, 31% depression and 26.3% were marked for life. At one time or another 29% of patients did not want to attend school because of the teasing. The grade retention rate amounted to 37.7% (20/53), and 2 patients were in special education classes. As a matter of fact, 50% of these children repeated their 1st or 2nd year of primary school. Furthermore, 47% of patients wanted to change something to their face, but 63% of them never spoke to their surgeon about additional surgeries even though they were teased in school. CONCLUSIONS: Taunting is common in children with CLP. This study highlights the high frequency and impact of taunting on the daily lives and self-perception of patients with CLP or CLP repair. It is important for healthcare professionals to be aware of this issue in the context of a multidisciplinary approach.

[Feasability study of screening for malignant lesions in the oral cavity targeting tobacco users]. / Faisabilité d'une stratégie de dépistage des lésions malignes de la cavité buccale chez les fumeurs.

INTRODUCTION: Oral cavity cancer is frequent. Prognosis of this cancer is closely linked to the development. Although the oral cavity is a potentially accessible site for examination, up to 50% of oral cancers are not detected until the disease is well advanced. PATIENTS AND METHOD: In a region where incidence rate is particularly high, local teams involved in screening, in epidemiological survey, in diagnosis and treatment of oral cancer performed a pilot feasibility study to improve strategy of early detection of oral cancer and premalignant lesion. Tobacco venders were solicited to distribute a flyer, which invite smokers to a free examination by general practitioner. General practitioners were invited to examine smokers, and to fill a predeterminate systematic oral cavity examination record during 3 months. They were asked to refer to a specialist if there was a potentially malignant disorder. RESULTS: The involvement of tobacco venders was rated as 67.3%. Ninety-three patients were included in 3 months. General practitioners referred 27% of the examinated patients. Among them, only 63.6% really saw a specialist, and a premalignant lesion was confirmed in 15.3%; further exams were carried out in 28.6%; a benign lesion was diagnosed in 57.1%. DISCUSSION/CONCLUSION: Original incentives for oral cavity screening were performed, based on multidisciplinary network. Nevertheless, it remains hardship to reach the targeted population and to maintain the patients in health system.

Anatomical study of the course of the inferior alveolar nerve in craniofacial microsomia using three-dimensional computed tomography: correlation with the Pruzansky classification.

Dysmorphogenesis of the mandible complicates assessment of the course of the inferior alveolar nerve in patients with craniofacial microsomia. Our aim in the present study was to correlate the anatomical description of the course with the Pruzansky classification (which indicates the severity of hemifacial microsomia), in the mandibles of 22 affected patients using 3-dimensional computed tomography (CT). We measured the distance between fixed landmarks on the normal and the microsomic sides. The normal sides served as controls. In the group of five patients with type I disease, we found no significant differences between the unaffected and the microsomic side. In the nine patients with Pruzansky type II disease morphological views of the course showed a between-side difference in the length of the bony canal and the height of the mandibular ramus. In the five patients with Pruzansky type III disease, there was no bony canal. Three-dimensional CT analysis may be of value in plotting the course of the inferior alveolar nerve and assisting the surgeon in mandibular osteotomy or distraction osteogenesis.

[Avoidable infant deaths in the 1993 and 2004 Pelotas birth cohorts, Rio Grande do Sul State, Brazil.] / Óbitos infantis evitáveis nas coortes de nascimentos de Pelotas, Rio Grandedo Sul, Brasil, de 1993 e 2004.

Infant mortality classified as avoidable (through immunization, adequate prenatal, childbirth, and neonatal care, adequate diagnostic and therapeutic measures, and adequate health promotion associated with appropriate health care) was compared in the 1993 and 2004 Pelotas Birth Cohorts, Rio Grande do Sul State, Brazil. Deaths were monitored by visits to hospitals, notary public offices, cemeteries, and the Regional Health Division and by a search in the Mortality Information System database. There were 5,249 live births and 111 infant deaths in the 1993 cohort and 4,231 live births and 82 infant deaths in 2004. The avoidable infant mortality rate was 15.2:1,000 live births in 1993 and 15.4 in 2004. Avoidable neonatal and post-neonatal mortality rates were 11.2 and 4.0, respectively, in 1993, and 10.9 and 4.5 in 2004. Preterm births were the main variable associated with avoidable mortality in both cohorts. Strategies to prevent preterm birth may help reduce infant mortality in this context.

Validation of the SenseWear armband in circuit resistance training with different loads.

The use of the SenseWear™ armband (SWA), an objective monitor of physical activity, is a relatively new device used by researchers to measure energy expenditure. These monitors are practical, relatively inexpensive and easy-to-use. The aim of the present study was to assess the validity of SWAs for the measurement of energy expenditure (EE) in circuit resistance training (CRT) at three different intensities in moderately active, healthy subjects. The study subjects (17 females, 12 males) undertook CRT at 30, 50 and 70% of the 15 repetition maximum for each exercise component wearing an SWA as well as an Oxycon Mobile (OM) portable metabolic system (a gold standard method for measuring EE). The EE rose as exercise intensity increased, but was underestimated by the SWAs. For women, Bland-Altman plots showed a bias of 1.13 ± 1.48 METs and 32.1 ± 34.0 kcal in favour of the OM system, while for men values of 2.33 ± 1.82 METs and 75.8 ± 50.8 kcal were recorded.

Avoidable deaths in the first four years of life among children in the 2004 Pelotas (Brazil) birth cohort study.

Avoidable deaths have been employed as indicators of health care quality. The aim of this study was to identify factors associated with avoidable deaths from birth to four years of age among children from the 2004 Pelotas (Brazil) birth cohort study. From January 1st, 2004, to December 31st, 2005, deaths were monitored on a daily basis and the causes were investigated and classified according to avoidability. After the first year, deaths were monitored through the Mortality Information System. A total of 94 children died during this period. It was possible to classify 92 deaths, 70 of which were preventable. Low family income, fewer prenatal visits and poor-quality prenatal care, preterm birth, low 5-minute Apgar score, and no breastfeeding in the first 24 hours of life were associated with increased risk of death. Prematurity was present in 39 deaths, but only five of these would have been prevented by measures provided during prenatal care. Although limited, compliance with antenatal care program guidelines is still the most important strategy for preventing avoidable deaths in childhood, particularly among the poorest children.

Os óbitos evitáveis têm sido utilizados como indicadores de qualidade da atenção à saúde. Este estudo teve como objetivo identificar os fatores associados aos óbitos evitáveis até os 4 anos de idade entre as crianças da Coorte de Nascimentos de Pelotas, Rio Grande do Sul, Brasil, de 2004. De 1º de janeiro de 2004 a 31 de dezembro de 2005, os óbitos foram monitorados diariamente, as causes, investigadas e classificadas conforme a evitabilidade. Após o primeiro ano, os óbitos foram monitorados por meio do Sistema de Informações sobre Mortalidade. Até os 4 anos, ocorreram 94 óbitos, sendo possível classificar 92, dos quais 70 seriam evitáveis. Baixa renda, menor número de consultas pré-natais, pré-natal de pior qualidade, prematuridade, baixo Apgar no 5º minuto e não mamar nas primeiras 24 horas associaram-se a risco aumentado de morrer por cause evitável. Prematuridade estava presente em 39 óbitos, mas somente 5 desses teriam sido prevenidos por intervenções no pré-natal. Embora limitada, a adesão às normas do programa de atenção pré-natal, especialmente entre as mais pobres, ainda é a principal estratégia para a prevenção das mortes evitáveis na infância.

Helicobacter pylori and anemia: a community-based cross-sectional study among adults in Southern Brazil / Helicobacter pylori e anemia: um estudo transversal de base populacional entre adultos no Sul do Brasil

To investigate the association between Helicobacter pylori and anemia, a community-based cross-sectional study was conducted among 18-45 year old users of the 31 primary health care units in Pelotas, Southern Brazil. Interviews using a structured questionnaire were carried out in waiting rooms during two work shifts. Anemia (hemoglobin < 11g/dL among pregnant women, < 12g/dL among women and < 13g/dL among men) was diagnosed from capillary blood (HemoCue) and H. pylori by means of a 13C-UBT. Information on socio-demographic, behavioral and biological characteristics was collected. Logistic and linear regression analyses were carried out, taking into account aggregated primary health care units. A total of 1,117 respondents fulfilled the inclusion criteria (losses/refusals: 8.1 percent). Prevalence of anemia was 20.6 percent (18.2-23.2 percent) and of H. pylori, 70.7 percent (68.0-73.6 percent). After allowing for age, sex and skin color the odds ratio for anemia among those who were diagnosed H. pylori positive was 0.94 (0.70-1.27). After allowing for sex, skin color, family monthly income, age, and smoking, the reduction in hemoglobin among H. pylori positive respondents was 0.07g/dL (-0.24-0.11; p = 0.4). There is no association between H. pylori and anemia among adults attending primary health care units in Southern Brazil.

Helicobacter pylori tem sido apontado como causa de anemia. Para investigar essa associação, estudo transversal de base populacional foi realizado entre adultos (18-45 anos de idade), usuários das 31 unidades básicas de saúde (UBS), em Pelotas, Sul do Brasil. Entrevistas com questionários estruturados foram feitas nas salas de espera, em dois turnos de trabalho. Anemia (hemoglobina < 11g/dL entre gestantes, < 12g/dL entre mulheres adultas e < 13g/dL entre homens) foi diagnosticada em sangue capilar (HemoCue). H. pylori foi identificado por 13C-Urea Breath Test. Foram coletadas informações sócio-demográficas, comportamentais e biológicas. Análise por regressão logística e linear, levando em conta a agregação por UBS. Dos 1.117 elegíveis, foram perdidos ou recusaram-se participar 8,1 por cento. A prevalência de anemia foi 20,6 por cento (18,2-23,2 por cento) e H. pylori, 70,7 por cento (68,0-73,6 por cento). Após ajuste para idade, sexo e cor, a odds ratio para anemia entre H. pylori positivos foi 0,94 (0,70-1,27). Na análise ajustada para sexo, cor, renda familiar, idade e tabagismo, o nível de hemoglobina foi 0,07g/dL menor (-0,24-0,11; p = 0,4) entre H. pylori positivos. Não há associação entre H. pylori e anemia entre adultos usuários de UBS no Sul do Brasil.

Validade de instrumento epidemiológico para rastrear H. pylori entre pacientes dispépticos / Validez del instrumento epidemiológico para rastrear H. pylori entre pacientes dispépticos / Validity of an epidemiologic instrument for H. pylori screening among dyspeptic patients

OBJETIVO:Validar um escore epidemiológico para identificar dispépticos positivos para Helicobacter pylori. MÉTODOS: Estudo transversal realizado com 434 indivíduos entre 18 e 45 anos de idade, portadores de dispepsia não investigada, usuários de unidades básicas de saúde de Pelotas (RS), entre 2006 e 2007. Dispepsia foi diagnosticada conforme Roma-II. O padrão-ouro para presença de H. pylori foi o teste respiratório com 13C-uréia. Analisou-se a associação entre H. pylori e variáveis independentes por regressão logística. O escore foi construído a partir de odds ratios ajustadas. Foram calculadas a sensibilidade, especificidade e valores preditivos. RESULTADOS: Dentre os dispépticos, a prevalência de H. pylori foi 74 por cento (IC 95 por cento: 69;77,7) e esteve associada diretamente à idade e número de irmãos na infância e inversamente à escolaridade, sendo essas variáveis utilizadas na construção do escore. Os valores do escore variaram de 3-9. Escores entre 7, 8 e 9 apresentaram sensibilidade, respectivamente, de 36,6 por cento, 22,3 por cento e 11,1 por cento; e valores preditivos positivos 87,8 por cento, 90,9 por cento e 92,1 por cento. Sem a aplicação do escore, três de cada quatro dispépticos receberiam tratamento para H. pylori, com a aplicação, menor número de dispépticos seriam encaminhados para tratamento (um em cada três, seis e 11, respectivamente, com os pontos de corte entre 7 e 9), porém às custas de alta taxa de casos falso-negativos. CONCLUSÕES: O escore não foi válido para identificação seletiva de dispépticos candidatos a tratamento erradicador para H. pylori. Diferentemente do recomendado para países desenvolvidos, a alta prevalência de H. pylori torna a estratégia testar-e-tratar inapropriada para uso nos países em desenvolvimento.
