Does the Addition of Mutations of CTNNB1 S45F to Clinical Factors Allow Prediction of Local Recurrence in Patients With a Desmoid Tumor? A Local Recurrence Risk Model.

BACKGROUND: The initial approach to the treatment of desmoid tumors has changed from surgical resection to watchful waiting. However, surgery is still sometimes considered for some patients, and it is likely that a few patients would benefit from tumor removal if the likelihood of local recurrence could be predicted. However, to our knowledge, there is no tool that can provide guidance on this for clinicians at the point of care. QUESTION/PURPOSE: We sought to explore whether a combined molecular and clinical prognostic model for relapse in patients with desmoid tumors treated with surgery would allow us to identify patients who might do well with surgical excision. METHODS: This was a retrospective, single-center study of 107 patients with desmoid tumors who were surgically treated between January 1980 and December 2015, with a median follow-up of 106 months (range 7 to 337 months). We correlated clinical variables (age, tumor size, and localization) and CTNNB1 gene mutations with recurrence-free survival. Recurrence-free survival was estimated using a Kaplan-Meier curve. Univariate and multivariable analyses of time to local recurrence were performed using Cox regression models. A final nomogram model was constructed according to the final fitted Cox model. The predictive performance of the model was evaluated using measures of calibration and discrimination: calibration plot and the Harrell C-statistic, also known as the concordance index, in which values near 0.5 represent a random prediction and values near 1 represent the best model predictions. RESULTS: The multivariable analysis showed that S45F mutations (hazard ratio 5.25 [95% confidence interval 2.27 to 12.15]; p < 0.001) and tumor in the extremities (HR 3.15 [95% CI 1.35 to 7.33]; p = 0.008) were associated with a higher risk of local recurrence. Based on these risk factors, we created a model; we observed that patients considered to be at high risk of local recurrence as defined by having one or two factors associated with recurrence (extremity tumors and S45F mutation) had an HR of 8.4 compared with patients who had no such factors (95% CI 2.84 to 24.6; p < 0.001). From these data and based on the multivariable Cox models, we also developed a nomogram to estimate the individual risk of relapse after surgical resection. The model had a concordance index of 0.75, or moderate discrimination. CONCLUSION: CTNNB1 S45F mutations combined with other clinical variables are a potential prognostic biomarker associated with the risk of relapse in patients with desmoid tumors. The developed nomogram is simple to use and, if validated, could be incorporated into clinical practice to identify patients at high risk of relapse among patients opting for surgical excision and thus help clinicians and patients in decision-making. A large multicenter study is necessary to validate our model and explore its applicability. LEVEL OF EVIDENCE: Level III, therapeutic study.

Clinical Characteristics and Mortality Profile of COVID-19 Patients Aged less than 20 years Old in Pernambuco - Brazil.

COVID-19 in children and adolescents has low frequency, severity, and fatality rate all over the world. A cross-sectional study was conducted to assess the epidemiological and clinical aspects of COVID-19 in patients younger than 20 years in Pernambuco (Brazil), with cases confirmed by reverse-transcriptase-PCR SARS-CoV-2 between 13 February and June 19, 2020, reported on information systems. Data regarding age (< 30 days, 1-11 months, 1-4 years, 5-9 years, 10-14 years, and 15-19 years), gender, color/race, symptoms, pregnancy or puerperium, comorbidities, hospitalization, and death were investigated. Fatality rate and mortality coefficient were calculated, and a multiple logistic regression analysis was performed to determine if gender, age, and comorbidities were factors associated with death. Of 682 pediatric cases, 52.8% were female, with a mean age of 9 ± 7.2 years. The most frequent symptoms were fever (64.4%), cough (52.4%), and respiratory distress (32.4%). Hospitalization was reported in 46.2% of cases, mainly among neonates (80.3%) and infants (73.8%). Thirty-eight deaths were notified, and a fatality rate of 5.6% (95% CI: 3.9-7.3) was found, with higher fatality rates among neonates 11.5% (7 of 61) and 9.5% (8 of 84) infants. The mortality coefficient was 10.9 per 100,000 inhabitants < 1 year of age, whereas comorbidities (Odds ratio [OR] = 14.13, 95% CI: 6.35-31.44), age < 30 days (OR = 5.17, 95% CI: 1.81-14.77), and age 1-11 months (OR = 3.28, 95% CI: 1.21-8.91) were independent factors associated with death. The results demonstrate the vulnerability of neonates and infants with severe conditions, need hospitalization, and high fatality rate, indicating the necessity to adapt public health policies for these age-groups.

Early postoperative outcomes among patients with delayed surgeries after preoperative positive test for SARS-CoV-2: A case-control study from a single institution.

BACKGROUND: There are limited data on surgical complications for patients that have delayed surgery after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We aimed to analyze the surgical outcomes of patients submitted to surgery after recovery from SARS-CoV-2 infection. METHODS: Asymptomatic patients that had surgery delayed after preoperative reverse-transcription polymerase chain reaction (RT-PCR) for SARS-CoV-2 were matched in a 1:2 ratio for age, type of surgery and American Society of Anesthesiologists to patients with negative RT-PCR for SARS-CoV-2. RESULTS: About 1253 patients underwent surgical procedures and were subjected to screening for SARS-CoV-2. Forty-nine cases with a delayed surgery were included in the coronavirus disease (COVID) recovery (COVID-rec) group and were matched to 98 patients included in the COVID negative (COVID-neg) group. Overall, 22 (15%) patients had 30-days postoperative complications, but there was no statistically difference between groups -16.3% for COVID-rec and 14.3% for COVID-neg, respectively (odds ratio [OR] 1.17:95% confidence interval [CI] 0.45-3.0; p = .74). Moreover, we did not find difference regarding grades more than or equal to 3 complication rates - 8.2% for COVID-rec and 6.1% for COVID-neg (OR 1.36:95%CI 0.36-5.0; p = .64). There were no pulmonary complications or SARS-CoV-2 related infection and no deaths within the 30-days after surgery. CONCLUSIONS: Our study suggests that patients with delayed elective surgeries due to asymptomatic preoperative positive SARS-CoV-2 test are not at higher risk of postoperative complications.

Sarcoma European and Latin American Network (SELNET) Recommendations on Prioritization in Sarcoma Care During the COVID-19 Pandemic.

BACKGROUND: The COVID-19 outbreak has resulted in collision between patients infected with SARS-CoV-2 and those with cancer on different fronts. Patients with cancer have been impacted by deferral, modification, and even cessation of therapy. Adaptive measures to minimize hospital exposure, following the precautionary principle, have been proposed for cancer care during COVID-19 era. We present here a consensus on prioritizing recommendations across the continuum of sarcoma patient care. MATERIAL AND METHODS: A total of 125 recommendations were proposed in soft-tissue, bone, and visceral sarcoma care. Recommendations were assigned as higher or lower priority if they cannot or can be postponed at least 2-3 months, respectively. The consensus level for each recommendation was classified as "strongly recommended" (SR) if more than 90% of experts agreed, "recommended" (R) if 75%-90% of experts agreed and "no consensus" (NC) if fewer than 75% agreed. Sarcoma experts from 11 countries within the Sarcoma European-Latin American Network (SELNET) consortium participated, including countries in the Americas and Europe. The European Society for Medical Oncology-Magnitude of clinical benefit scale was applied to systemic-treatment recommendations to support prioritization. RESULTS: There were 80 SRs, 35 Rs, and 10 NCs among the 125 recommendations issued and completed by 31 multidisciplinary sarcoma experts. The consensus was higher among the 75 higher-priority recommendations (85%, 12%, and 3% for SR, R, and NC, respectively) than in the 50 lower-priority recommendations (32%, 52%, and 16% for SR, R, and NC, respectively). CONCLUSION: The consensus on 115 of 125 recommendations indicates a high-level of convergence among experts. The SELNET consensus provides a tool for sarcoma multidisciplinary treatment committees during the COVID-19 outbreak. IMPLICATIONS FOR PRACTICE: The Sarcoma European-Latin American Network (SELNET) consensus on sarcoma prioritization care during the COVID-19 era issued 125 pragmatical recommendations distributed as higher or lower priority to protect critical decisions on sarcoma care during the COVID-19 pandemic. A multidisciplinary team from 11 countries reached consensus on 115 recommendations. The consensus was lower among lower-priority recommendations, which shows reticence to postpone actions even in indolent tumors. The European Society for Medical Oncology-Magnitude of Clinical Benefit scale was applied as support for prioritizing systemic treatment. Consensus on 115 of 125 recommendations indicates a high level of convergence among experts. The SELNET consensus provides a practice tool for guidance in the decisions of sarcoma multidisciplinary treatment committees during the COVID-19 outbreak.

What is the impact of local control in Ewing sarcoma: analysis of the first Brazilian collaborative study group - EWING1.

BACKGROUND: Relapse in localized Ewing sarcoma patients has been a matter of concern regarding poor prognosis. Therefore, we investigated the impact of local control modality (surgery, surgery plus radiotherapy, and radiotherapy) on clinical outcomes such as survival and recurrence in patients with non-metastatic Ewing sarcoma treated on the first Brazilian Collaborative Group Trial of the Ewing Family of Tumors (EWING1). METHODS: Seventy-three patients with localized Ewing sarcoma of bone aged < 30 years were included. The treating physicians defined the modality of local control based on the recommendations of the coordinating center and the patient and tumor characteristics. Possible associations of local control modality with local failure (LF), disease-free survival (DFS), event-free survival (EFS), overall survival (OS), and clinical characteristics were analyzed. RESULTS: Mean patient age was 12.8 years (range, 2 to 25 years) and median follow-up time was 4.5 years (range, 2.3 to 6.7 years). Forty-seven patients underwent surgery, 13 received radiotherapy, and 13 received both. The 5-year EFS, OS, and DFS for all patients was 62.1%, 63.3%, and 73.1%, respectively. The 5-year cumulative incidence (CI) of LF was 7.6% for surgery, 11.1% for radiotherapy, and 0% for postoperative radiotherapy (PORT) (p = 0.61). The 5-year EFS was 71.7% for surgery, 30.8% for radiotherapy, and 64.1% for PORT (p = 0.009). CONCLUSIONS: There was a significant effect of local control modality on EFS and OS in the study. Surgery and PORT modalities yielded very close results. The group treated with radiotherapy alone had considerably worse outcomes. This may be confounded by greater risk factors in these patients. There was no significant effect of local control modality on the CI of LF and DFS.

Brazilian adaptation and validation of the Empowerment of Parents in the Intensive Care-Neonatology (EMPATHIC-N) questionnaire / Adaptação brasileira e validação do questionário Empowerment of Parents in the Intensive Care-Neonatology (EMPATHIC-N)

Abstract Objectives: Considering the lack of questionnaires that propose to evaluate parental satisfaction with the Neonatal Intensive Care Unit (NICU) in Brazil, this study aimed to carry out the translation of the EMPATHIC-N questionnaire into Brazilian Portuguese, the cross-cultural adaptation and validation of its contents. Method: The translation and cultural adaptation of the questionnaire was carried out according to the protocol established by the Translation and Cross-Cultural Adaptation Group of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) in 2005. The validation of the content was carried out by a panel of experts, who evaluated each item from "very irrelevant" to "very relevant". Items with a mean Likert scale value <3.5 were excluded. Cronbach's alpha of the domains was calculated. Results: The questionnaire was submitted to two pilot tests with mothers of newborns admitted to the NICU of the study, after which some terms were modified to achieve global understanding. Cronbach's alpha remained above 0.7 in all items. Conclusion: The tool resulting from the translation, cultural adaptation, and validation of the EMPATHIC-N questionnaire showed to be adequate to assess satisfaction of parents of newborns admitted to the NICU in Brazil.

Resumo Objetivos: Considerando a ausência de questionários que se proponham a avaliar satisfação de pais em Unidade de Cuidados Intensivos Neonatal (UCIN) no Brasil, o presente estudo teve o objetivo de fazer a tradução do questionário Empowerment of Parents in the Intensive Care- Neonatology (Empathic-N) para o português brasileiro, adaptação transcultural e validação de seu conteúdo. Método: Foi feita tradução e adaptação transcultural do questionário, segundo protocolo estabelecido pelo Grupo da Tradução e Adaptação Transcultural da Sociedade Internacional para Pesquisas Farmacoeconômicas (Ispor) em 2005. A validação do conteúdo foi feita por um comitê de especialistas, que avaliaram cada item de “muito irrelevante” a “muito relevante”.

Comparison of the Protective Effects of Individual Components of Particulated trans-Sialidase (PTCTS), PTC and TS, against High Cholesterol Diet-Induced Atherosclerosis in Rabbits.

Previous studies showed the presence of Mycoplasma pneumoniae (M. pneumoniae) and membrane-shed microparticles (MPs) in vulnerable atherosclerotic plaques. H&S Science and Biotechnology developed PTCTS, composed by natural particles from medicinal plants (PTC) combined with trans-Sialidase (TS), to combat MPs and Mycoplasma pneumoniae. Our aim was to determine the effects of the different components of PTCTS in a rabbit model of atherosclerosis. Rabbits were fed with high cholesterol diet for 12 weeks and treated during the last 6 weeks with either vehicle, PTC, TS, or PTCTS. Lipid profile and quantification of MPs positive for Mycoplasma pneumoniae and oxidized LDL antigens were carried out. Aortas and organs were then histologically analyzed. PTCTS reduced circulating MPs positive for Mycoplasma pneumoniae and oxidized LDL antigens, reduced the plaque area in the abdominal aorta, and caused positive remodeling of the ascendant aorta. PTC caused positive remodeling and reduced plaque area in the abdominal aorta; however, TS had a lipid lowering effect. PTCTS components combined were more effective against atherosclerosis than individual components. Our data reinforce the infectious theory of atherosclerosis and underscore the potential role of circulating MPs. Therefore, the removal of Mycoplasma-derived MPs could be a new therapeutic approach in the treatment of atherosclerosis.

Toxicological and hematological effect of Terminalia arjuna bark extract on a freshwater catfish, Heteropneustes fossilis.

Increasing demand for eco-friendly botanical piscicides and pesticides as replacements for harmful synthetic chemicals has led to investigation of new sources of plant materials. Stem bark of Terminalia arjuna, which has been used as a popular folk medicine since ancient time, was examined for its piscicidal activity. This study aims to determine toxicity of ethanol extract of T. arjuna bark on fresh water stinging catfish (Heteropneustes fossilis), along with evaluation of changes in hematological parameters of the fishes exposed to a lethal concentration. The percent mortality of fishes varied significantly in response to concentrations of the extract and exposure times (between exposure time F = 36.57, p < 0.001; between concentrations F = 39.93, p < 0.001). The lethal concentrations (LC50) of ethanol extract were found to be 12.7, 8.94, 5.63 and 4.71 mg/l for 24, 48, 72 and 96 h, respectively. During acute toxicity test, blood samples of treatment fishes showed significant decreases in the red blood cells count, hematocrit content, hemoglobin concentration, mean corpuscular hemoglobin concentration and plasma protein level when compared to those of the control group, while there were significant increases in the mean corpuscular volume, mean corpuscular hemoglobin, white blood cells count and plasma glucose concentration. These results suggest that T. arjuna bark extract could be considered as a potent piscicide due to its toxic effect on fish, particularly fish hematology.

Do imaginário normativo a realidade da Rede de Atenção às Urgências / From normative imaginary reality of the Network of Emergency Care

Modelo do estudo: estudo de caso. Objetivo: analisar a Rede de Atenção às Urgências sob a ótica do Serviço de Atendimento Móvel de Urgência (SAMU) Metropolitano do Recife. Material e Método: estudo de caso com múltiplas unidades de análise. O caso foi o SAMU Metropolitano do Recife e as unidades de análise foram os componentes: promoção, prevenção à saúde e vigilância; organização e governança da rede. Optou-se pela triangulação de métodos e de fontes, utilizando entrevista semiestruturada com 57 profissionais que atuavam nesse serviço; observação direta e documentos oficiais (banco de dados, portarias e relatórios). Para a análise dos dados qualitativos utilizou-se a técnica de condensação de significados e para os quantitativos, a frequência média dos eventos. Resultados: O perfil dos profissionais entrevistados mostra que 53% era do sexo masculino, 65% graduados há menos de 12 anos, um pouco mais da metade atuava no SAMU há menos de 2 anos e 77% tinham vínculo empregatício temporários por meio de contratos com as prefeituras. Segundo os entrevistados há estratégias de promoção e prevenção, mas, não conseguem visualizar mudanças no perfil epidemiológico e demográfico como resultado da implantação dessas estratégias. Existe uma distribuição inadequada dos equipamentos de saúde; baixa cobertura populacional dos pontos de atenção à saúde (50% de cobertura de PSF/ESF e déficit de 3.089 leitos hospitalares do SUS) e, falta de coordenação do comitê gestor estadual regional do sistema de atenção as urgências pela Secretaria do Estado de Pernambuco...

Autologous Platelet Gel: Five Cases Illustrating Use on Sickle Cell Disease Ulcers.

Leg ulcers represent a particularly disabling complication in patients with sickle cell disease (SCD). Platelet gel (PG) is a novel therapeutic strategy used for accelerating wound healing of a wide range of tissues through the continuous release of platelet growth factors. Here, we describe the use of PG preparation according to Anitua's PRGF (preparations rich in growth factors) protocol for treating chronic nonhealing ulcers in patients with SCD. A positive response occurred in 3 patients with an area reduction of 85.7% to 100%, which occurred within 7 to 10 weeks, and a 35.2% and 20.5% of area reduction in 2 other patients, who however, had large ulcers. After calcium chloride addition, the platelet-rich plasmas demonstrated enhanced platelet-derived growth factors-BB (P < .001), transforming growth factor-ß1 (P = .015), vascular endothelial growth factors (P = .03), and hepatocyte growth factors (nonsignificant) secretion. Furthermore, calcium chloride addition induced a significant decrease in platelet number (P = .0134) and there was no leukocyte detection in the PG product. These results demonstrate that PG treatment might impact the healing of leg ulcers in sickle cell disease, especially in patients with small ulcers.

Water quality assessment of an unusual ritual well in Bangladesh and impact of mass bathing on this quality.

A sacred ritual well with continuously discharging of methane gas through its water body was studied for physicochemical and microbiological quality in three seasons and during ritual mass bathing. Most of the physicochemical parameters showed significant seasonal variations (P<0.05) and a sharp fluctuation during mass bathing. Dissolved oxygen (DO) was found negatively correlated with temperature (r=-0.384, P<0.05), biochemical oxygen demand (BOD) (r=-0.58, P<0.001) and ammonia (r=-0.738, P<0.001), while BOD showed positive correlation with chemical oxygen demand (COD) (r=0.762, P<0.001) and ammonia (r=0.83, P<0.001). Simple regression analysis also yielded significant linear relationship in DO vs. temperature (r(2)=0.147, P<0.05), DO vs. ammonia (r(2)=0.544, P<0.001) and BOD vs. DO (r(2)=0.336, P<0.001). A total of eight microbial indicators were studied and found that all of them increased unusually during mass bathing comparing with their respective seasonal values. Total coliforms (TC) were found positively correlated with fecal coliforms (FC) (r=0.971), FC with Escherichia coli (EC) (r=0.952), EC with intestinal enterococci (IE) (r=0.921), fecal streptococci (FS) with IE (r=0.953) and Staphylococcus aureus (SA) with Pseudomonas aeruginosa (PA) (r=0.946), which were significant at P<0.001. Some regression models showed significant linear relationship at P<0.001 with r(2) value of 0.943 for FC vs. TC, 0.907 for EC vs. FC, 0.869 for FS vs. FC, 0.848 for IE vs. EC and 0.909 for IE vs. FS. The overall results found in this study revealed that well water is suitable for bathing purpose but the religious activity considerably worsen its quality.

Correlation of bacterial coinfection versus matrix metalloproteinase 9 and tissue inhibitor of metalloproteinase 1 expression in aortic aneurysm and atherosclerosis.

BACKGROUND: We searched for any relationship between Chlamydophila pneumoniae, Mycoplasma pneumoniae, matrix metalloproteinase 9 (MMP-9), and tissue inhibitor of metalloproteinase 1 (TIMP-1) in aneurysmatic atherosclerotic lesions, and whether this relationship differed from that in atherosclerotic nonaneurysmatic lesions. METHODS: Twenty-eight tissue samples paired by age and sex were grouped as follows: group 1 included 14 nonaneurysmal atherosclerotic fragments obtained from abdominal aortas collected from necropsies; group 2 included 14 aneurysmatic atherosclerotic aortic fragments obtained from patients during corrective surgery. Immunohistochemistry reactions were evaluated for C pneumoniae, M pneumoniae, MMP-9, and TIMP-1 antigens. Both groups were compared using the Mann-Whitney test, and the correlations among variables were obtained using the Spearman correlation test. P ≤ 0.05 was considered statistically significant. RESULTS: C pneumoniae and M pneumoniae antigens were detected in 100% of cases. A higher amount of C pneumoniae (P = 0.005), M pneumoniae (P = 0.002), and MMP-9 (P = 0.021) was found in adventitia of group 2 with aneurysm. A positive correlation was found in the aneurysm group, as follows: intima C pneumoniae versus adventitia thickness (r = 0.70; P = 0.01), media C pneumoniae versus adventitia C pneumoniae (r = 0.75; P = 0.002), intima C pneumoniae versus media C pneumoniae (r = 0.8; P = 0.00), and adventitia C pneumoniae versus intima M pneumoniae (r = 0.54; P = 0.05); negative correlations were as follows: adventitia thickness and adventitia M pneumoniae (r = -0.65; P = 0.01), media MMP-9 and media thickness (r = -0.55; P = 0.04), TIMP-1 media versus adventitia C pneumoniae (r = -0.86; P = 0.00), and TIMP-1 media versus M pneumoniae intima (r = -0.67; P = 0.03). Nonaneurysmal atherosclerotic group 1 results are as follows: adventitia C pneumoniae versus TIMP-1 media (r = 0.75; P = 0.01) and media C pneumoniae and adventitia C pneumoniae (r = 0.59; P = 0.03). CONCLUSIONS: The present work favors a role for coinfection of both M pneumoniae and C pneumoniae in the development of aortic atherosclerotic aneurysm, with increased adventitial inflammation, inhibition of TIMP-1 activity, and increased collagen degradation.

Anxiolytic-like and sedative effects of Hydrocotyle umbellata L., Araliaceae, extract in mice

The plant Hydrocotyle umbellata L., Araliaceae (water pennywort), is widely used in Brazilian folk medicine to reduce anxiety. This work investigates the anxiolytic-like effects of the ethanol extract from H. umbellata subterraneous parts as well as the extract's other putative central nervous system effects that could justify its common use. Oral dosing of the extract (0.3 and 1 g/kg) clearly showed an anxiolytic-like profile in the elevated plus maze test where it increased the percentage of entries into and the time spent in the open arms of the maze. In the marble-burying test, the extract induced anxiolytic-like effects only at a dose of 1 g/kg, which also causes mild sedative properties in other models. The sedated state was characterized by a slight reduction in spontaneous exploratory activity during the open field test and a potentiating of pentobarbital-induced hypnosis. No signs of motor impairment were detected in the rota rod or chimney tests. The extract did not show antidepressant properties in mice as assessed by the forced swimming test. These results support the use of H. umbellata in Brazilian folk medicine as an anxiolytic and contribute to the scientific knowledge of this possible phytotherapeutic resource.

[Evaluation of the historical series of live births at a tertiary health service--1991 to 2000]. / Avaliação da série histórica dos nascidos vivos em unidade terciária de Pernambuco--1991 a 2000.

OBJECTIVES: This study aimed to analyze some variables found in the Birth Certificates at the Instituto Materno Infantil de Pernambuco, Recife, from July 1991 to December 2000, according to Sinasc (National Information's data base of Births). METHODS: The statistical analysis was performed using the chi-square test for trend (p<0.05) on EpiInfo software (version 6.0), considering the years 1993 to 2000. RESULTS: The sample comprised a predominance of non-surgical deliveries, adequate gestational age of newborns, weight > 2500 g, Apgar score 1st min and 5th min between 8-10 and mature mothers who had attended from 4 to 6 appointments at prenatal care system. It showed the following rates: cesarean-section of 29.4% to 35.2% (chi2 = 73.7; p<0.01), low weight at birth of 15.9% to 22.8% (chi2 = 170.6; p < 0.01); premature newborns of 9.7% to 23.8% (chi2 = 503.6; p<0.01); teenage mothers of 24.1% to 28.8% (chi2 = 13.3; p<0.01), moreover a high percentage of newborns with Apgar index lower than 3 at the 1st minute (3.4% to 5.%) and (0.7% to 1.6%) at the 5th minute. CONCLUSION: These results confirm the role of IMIP as an institution for referral of high-risk pregnancies in Pernambuco.

CONCLUSÕES: Os resultados ratificam a caracterização do IMIP como hospital de complexidade terciária e de referência para gestantes e recém-nascidos de alto risco no Estado de Pernambuco.

Expansor ósseo para maxila posterior: técnica Passadore / Bone expander for posterior maxilla: Passadore technique

Os diversos tipos de osso e sua variada anatomia representam muitas vezes limitações para perfurações com brocas para colocação de implantes osseointegrados. O desenvolvimento da técnica dos expansores, que permite a implantação sem ou com pouco uso de brocas, veio solucionar problemas críticos em muitos casos. Vários autores comprovaram excelentes resultados com o uso dessa técnica. Mesmo assim, algumas limitações ainda são encontradas para o adequado uso desses instrumentos, devido a suas dimensões e design. Nesse trabalho mostramos a modificação da técnica de Summers, com expansores mais curtos, permitindo seu emprego na maxila posterior, com catraca, com chave digital e em região anterior com a chave T

Ventricular expression of atrial natriuretic peptide in chronic chagasic cardiomyopathy is not induced by myocarditis.

BACKGROUND: The ventricles of the normal heart are virtually devoid of atrial natriuretic peptide (ANP). Although ANP occurs in ventricles submitted to elevated wall stress, it is not clear whether ANP expression is affected by myocarditis. We investigated the immunohistochemical expression of ANP in chronic chagasic cardiomyopathy, an inflammatory cardiomyopathy caused by infection with the protozoan Trypanosoma cruzi. METHODS: Necropsy samples from the left and right ventricles of 16 patients exhibiting chronic chagasic cardiomyopathy were evaluated for myocarditis, fibrosis, T. cruzi parasites and ANP immunoreactivity. The diameters of 50 myocytes per sample were measured. RESULTS: ANP was present in myocytes of the subendocardial region in 13/16 (81.3%) left and 10/16 (62.5%) right ventricular samples (P=0.25). Myocytes present in the inflammatory foci, near the infiltrating inflammatory cells but distant from the subendocardial region, did not express ANP. Trypanosoma cruzi parasites exhibited intense immunoreactivity for ANP. The mean myocyte diameter and the incidence of myocarditis, fibrosis, and T. cruzi parasites was similar between the left and right ventricular samples. No statistical differences were found between the ANP-positive and ANP-negative cases. CONCLUSIONS: In chronic chagasic cardiomyopathy, both ventricles exhibit hypertrophy, fibrosis and ANP in the subendocardial region. The inflammatory infiltrate does not induce ANP expression in the myocytes. Regional stress but not myocarditis itself, is probably responsible for ventricular ANP expression in myocarditis.

Vigilância de óbitos infantis como indicador da efetividade do sistema de saúde - estudo em um município do interior do Nordeste brasileiro / Infant death surveillance as an indicator of health care system effectiveness - a study conducted in northeastern Brazil

Objetivo: avaliar, a partir do óbito infantil, o acesso e a qualidade da atenção Ó saúde prestada as crianças no município, durante a doença que levou ao óbito. Métodos: estudo descritivo de corte transversal, censitário, desérie de casos de óbitos infantis ocorridos em Bom Conselho, Pemambuco, no período de 1/1/1999 a 31/12/1999, identificados atravÚs do Sistema de Informação sobre Mortalidade, unidades de saúde, cartórios, cemitérios, agentes de saúde e parteiras. Os dados foram coletados mediante entrevistas domiciliares e revisÒo deprontußrios, em instrumentos específicos. Resultados: foram investigados 71 dos 72 óbitos identificados,com perda de 1,4por cento. A maioria (69,4por cento) ocorreu no periodo pós-neonatal. Do total, 67,6por cento aconteceram no domicilio, 77,5por cento procuraram assistÛncia pelo menos uma vez, sendo as emergências as mais procuradas (65,1por cento), porém 22,5 por cento não foram levados a nenhum serviço de saúde. A maioria dos serviços de saúde (90,9por cento ) estava a menos de uma hora de distância dos domiclios, 78,5por cento, localizados no município de residência, e 97 por cento dos atendimentos foram realizados por mÚdicos. Das 88 consultas realizadas, 39,8por cento terminaram com intemamento, e 27,3por cento foram atendidos e dispensados sem marcação da consulta de retomo, e 84 por cento receberam todas as medicaçÕes gratuitamente. Conclusões: através da vigilância dos óbitos, foi possível...
