ABSTRACT

Objective: To report a case of prenatal diagnosis of cardiac rhabdomyoma (CR) and neonatal surgical treatment as well as undertaking a systematic review of the literature to determine most frequent localization of CR, common signs and symptoms, associated pathologies, incidence of surgery, and prognoses for CR.Methods: We conducted systematic review of the literature on CR that were diagnosed and treated in the perinatal period, searching for English language articles in the PubMed/Medline database that were published within the past 20 years, using the following search terms: "cardiac rhabdomyoma"; "neonates"; "newborn"; "surgery".Results: Eighty-two studies were selected, but only 46 studies met the inclusion criteria. After birth, the majority of newborns were asymptomatic; however, murmurs and arrhythmia were also the two most prevalent signs of CR. The most prevalent location was the ventricles, corresponding to 40.3% of all cases, with 53% of these having a rhabdomyoma in the left ventricle. The incidence of multiple tumors was 56%, and in those cases the location of tumors was also most common in the ventricles. Tuberous sclerosis was the most commonly associated pathology, being present in 72% of cases of CR. Surgical treatment occurred in 27% of cases, and 3% of cases required surgery and prostaglandin. Regarding the perinatal outcome, 6% of cases resulted in fetal or neonatal death.Conclusion: CR are benign tumors which tend to spontaneously regress during early childhood but may have unfavorable outcomes in the presence of obstructive lesions and arrhythmias. Surgery is generally necessary in symptomatic patients.

ABSTRACT

BACKGROUND: Triple-negative breast cancer (TNBC) is a subtype of cancer, which tests negative for estrogen receptors, progesterone receptors, and lacks overexpression of the human epidermal growth factor 2 (C-erbB2, HER2/neu) gene. The expression of chemokines and their receptors, including CCR7, has been described in several types of cancer, contributing to tumor progression. AIM OF THE STUDY: This study investigated the association between the membrane and cytoplasmic CCR7 expression and the prognosis of TNBC. MATERIALS AND METHODS: Surgical paraffin histopathology blocks and clinico-pathological data were assessed from 133 patients. Samples were analyzed by immunohistochemistry and immunofluorescence using the Tissue Microarray technique for scoring the intensity of CCR7 expression. RESULTS: TNBC patients in which the CCR7 labeling was predominantly in the cytoplasm of tumor cells presented increased local tumor recurrence (P = 0.033). Conversely, there was no statistical difference in five-year overall survival between the patients with low (77%) versus high (80%) cytoplasmic CCR7 expression (P = 0.7104). Additionally, the risk of death between these groups was 1.19 (95% CI = 0.48-2.91). CONCLUSION: The cytoplasmic CCR7 expression associates with an increased incidence of tumor relapse in TNBC, not affecting patients survival. Consequently, the cell compartment in which the CCR7 localizes could serve as a prognostic marker in this cancer subtype.

ABSTRACT

Chagas disease (CD) affects approximately 6-7 million people worldwide, from which 30% develop chronic Chagas cardiomyopathy (CCC), usually after being asymptomatic for years. Currently available diagnostic methods are capable of adequately identifying infected patients, but do not provide information regarding the individual risk of developing the most severe form of the disease. The identification of biomarkers that predict the progression from asymptomatic or indeterminate form to CCC, may guide early implementation of pharmacological therapy. Here, six circulating microRNAs (miR-19a-3p, miR-21-5p, miR-29b-3p, miR-30a-5p, miR-199b-5p and miR-208a-3p) were evaluated and compared among patients with CCC (n = 28), CD indeterminate form (n = 10) and healthy controls (n = 10). MiR-19a-3p, miR-21-5p, and miR-29b-3p were differentially expressed in CCC patients when compared to indeterminate form, showing a positive correlation with cardiac dysfunction, functional class, and fibrosis, and a negative correlation with ejection fraction and left ventricular strain. Cardiac tissue analysis confirmed increased expression of microRNAs in CCC patients. In vitro studies using human cells indicated the involvement of these microRNAs in the processes of cardiac hypertrophy and fibrosis. Our study suggests that miRNAs are involved in the process of cardiac fibrosis and remodeling presented in CD and indicate a group of miRNAs as potential biomarkers of disease progression in CCC.

ABSTRACT

PURPOSE OF REVIEW: Chagas cardiomyopathy is a major public health disease in Latin America and, due to migration, is becoming a worldwide health and economic burden. This review sought to present the clinical and epidemiological aspects of Chagas cardiomyopathy, as well as some specific features and principles of treatment. We also retrospectively assessed our institutional experience with mechanical circulatory support in refractory heart failure due to Chagas cardiomyopathy over a 10-year period. RECENT FINDINGS: The role of antiparasitic treatment in patients with heart failure due to Chagas cardiomyopathy is controversial. Heart transplantation, although formerly contraindicated, is currently established as an important therapeutic option. Also, the favorable characteristics of Chagas patients, such as younger age, little comorbidity, and no reoperations or severe pulmonary hypertension, could be an advantage for a mechanical circulatory support indication in advanced heart failure due to Chagas cardiomyopathy. Despite the absence of large evidence-based data, much has been accomplished since Carlos Chagas' discovery one century ago. Our institutional experience shows that mechanical circulatory support in Chagas patients is associated with more successful bridging to heart transplantation when compared to non-Chagas patients.

ABSTRACT

Introdução: O dorso reto tem sido sempre um ideal na rinoplastia estética. A simples remoção da giba tem sido o método clássico e mais utilizado, mas pode ter consequências estéticas e funcionais adversas. Ainda existe grande resistência a procedimentos de aumento, porque a maioria dos pacientes solicitam redução e porque os benefícios de melhoria do equilíbrio nasal pelo aumento não são intuitivos. Um nariz aumentado pode parecer menor, o que é um benefício em particular em pacientes com pele espessa ou com o aspecto de terço inferior grande. Por outro lado, a percepção de redução com o aumento do radix e da ponta é muito comum, embora nunca tenha sido medida. Métodos: Esse estudo cria intervenções gráficas e reais para criar um dorso reto por meio do aumento do radix e da ponta e analisa como os pacientes e observadores independentes percebem as modificações. Analisou-se uma amostra de 42 casos consecutivos de rinoplastia. Desses, foram incluídos os que tinham dorso convexo e eram cirurgias primárias, restando 9 casos. Resultados: Houve aumento médio de 6,5% no tamanho do nariz na após a modificação gráfica, enquanto houve percepção de redução do nariz (p = 0,004). Houve aumento médio de 1% após a rinoplastia, enquanto houve percepção de redução. Conclusão: A retificação do dorso nasal pelo aumento do radix e da ponta causa percepção de redução do nariz.


Introduction: A straight bridge has always been the aesthetic ideal. Simple hump removal, the classical and most commonly applied method, can have aesthetic and functional consequences. However, great resistance to augmentation procedures persists because most patients request reduction and the benefits of improving nasal balance are counterintuitive. An augmented nose can look smaller, a particular benefit in patients with thick, inelastic skin or a large lower nose. On the other hand, decreased size perception after raising of the radix and tip is very common but has not been measured to date. Methods: This study created graphic and real interventions to achieve a straight bridge through radix and tip raising and analyzed how patients and independent observers perceive these changes. A sample of 42 sequential rhinoplasty patients was analyzed, including nine cases of primary surgery and dorsal convexity. Results: There was a 6.5% mean augmentation after graphic computing intervention but a perception of size reduction (p = 0.004). There was a 1% mean augmentation after rhinoplasty and an overall size reduction perception. Conclusion: Correction of the nasal dorsum, making a straight bridge through slightly increasing radix and tip, creates the perception of a decreased nose size.
