The Use of a High Flow PICC Catheter for Stem Cell and Lymphocyte Apheresis: The Initial Experience of a Pediatric Oncology Center in Brazil.

BACKGROUND: Autologous hematopoietic stem cell transplant (HSCT), characterized by high intensity chemotherapy followed by the infusion of HSC previously collected from the peripheral blood, is a procedure used in the treatment of several malignancies. In pediatrics, the apheresis procedure represents a challenge, due to the need for insertion of a rigid central venous catheter (CVC) in small children. The CVC is usually used for stem cell collection and then removed. Later, the patient will need a new device for cell infusion. AIM: We propose the use of one single catheter for both apheresis and infusion. METHODS: We present five children between 1 and 13 years of age who underwent apheresis using a high flow PICC catheter surgically inserted. RESULTS: All patients utilized a PICC line double lumen 5Fr (PowerPICC™ 5Fr DL BARD/USA) placed in the brachiocephalic vein tunneled on the chest, inserted under 24 h prior to apheresis to assure the devices were pervious. Three of the patients were diagnosed with solid tumor and one with acute lymphoblastic leukemia (ALL) awaiting Car-T Cell therapy. The four children who underwent autologous HSCT used the same catheter for cell infusion and remained with the catheter following discharge. The child who was submitted for Car-T Cell still awaits infusion and the catheter was removed. CONCLUSIONS: High flow PICC is a viable alternative for apheresis to maintain an adequate flow of 5 ml/s and can be used as a single catheter throughout the HSCT process, reducing the risks from anesthesia and the catheter insertion procedure.

Characterization of Physicochemical and Sensory Properties of Cheeses Added with Bovine Colostrum.

The objective of this study was to develop fresh and matured cheeses with different bovine colostrum levels, aiming to promote the consumption of dairy products with the addition of colostrum. Four different cheese formulations were produced with a mixture of 0:100, 15:85, 20:80, and 25:75, bovine colostrum:milk (v:v), and aged for 0, 10, 20, and 40 days. Milk, colostrum, and fresh and matured cheeses were submitted to physicochemical characterization. Moreover, microbiological quality, yield, texture profile, color, and sensory acceptance of cheese samples were evaluated. Colostrum supplementation favored low acidity, high moisture, a pH range of 5.0-6.2, and water activity of 0.94-99. Sensory attributes and overall evaluation of all cheese formulations achieved an Acceptability Index above 70, indicating good acceptability. Since cheese with colostrum presented the potential to be used as human food, assessing the presence of colostrum bioactive components in those dairy products is a promising goal for further research.

The Brazilian TP53 mutation (R337H) and sarcomas.

Sarcomas represent less than 1% of all solid neoplasms in adults and over 20% in children. Their etiology is unclear, but genetic susceptibility plays an important role in this scenario. Sarcoma is central in Li-Fraumeni Syndrome (LFS), a familial predisposition cancer syndrome. In Brazil, the high prevalence of p.Arg337His mutations in the TP53 gene brings about a unique condition: a cluster of LFS. In the present work, we studied 502 sarcoma patients not selected by age or family history in an attempt to assess the impact of the so-called "Brazilian germline TP53 mutation" (p.Arg337His) on this tumor type. We found that 8% of patients are carriers, with leiomyosarcoma being the main histologic type of sarcoma, corresponding to 52.5% of the patients with the mutated TP53 gene. These findings emphasize the importance of genetic counseling and can better guide the management of sarcoma patients.

Measuring Spiritual Well-Being in Brazilian Adolescents with Chronic Illness Using the FACIT-Sp-12: Age Adaptation of the Self-Report Version, Development of the Parental-Report Version, and Validation.

Spiritual well-being is a major issue in health care, but instruments for measuring this construct in adolescents are lacking. This study adapted the 12-item Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale (FACIT-Sp-12) for use with Brazilian adolescents with chronic diseases and developed a parental observer-rated version, using an expert panel, back-translation, and cognitive interviews with 72 participants. The psychometric properties of both versions were verified with two- and three-factor models by testing with 212 participants. The self- and parental-reported versions showed face validity, content validity, and acceptable levels of internal consistency for the overall scale and the two-factor model. The convergent validity was satisfactory for most items in both two- and three-factor models, but there was a lack of discrimination in the three-factor model using multitrait-multimethod analysis. This study presents the first instrument to assess the spiritual well-being of adolescents from their point of view and to allow their parents to serve as evaluators. However, we recommend further psychometric testing of the self- and parental-report scales to assess spiritual well-being in adolescents with chronic diseases in Brazil.

Linfoma de Burkit associado à obstrução de vias biliares / Biliary tract obstruction secundary to Burkitt lymphoma

Objetivo: Linforna não-Hodgkin (LNH) tipo Burkitt esporádico tem seu sítio primário em abdome, especialmente região ileocecal, apêndice e cólon. O envolvimento das vias biliares nesses pacientes é raro. Os autores relatam um paciente portador de LNH abdominal no qual a icterícia conseqüente à obstrução das vias biliares foi o sinal clínico inicial.Descrição: Menino de três anos e dois meses de idade, branco, com história de icterícia, acoliafecal, colúria e aumento do volume abdominal há um mês. Exame físico revelou icterícia 3+/4+, leve descoramento de mucosas, abdome pouco distendido, timpânico, com fígado palpável a 4,0 cm do rebordo costal direito. Exames laboratoriais revelaram bilirrubina total = 8,2 mg/dl (direta = 7,8 mg/dl) e anemia hipocrômica e microcítica. A ultra-sonografia (US) e a tomografia computadorizada (TC) de abdome mostraram duas lesões sólidas delimitadas em topografia hilar hepática, com dilatação de vias biliares intra-hepáticas. O estudo ultra-sonográfico com Doppler mostrou deslocamento da artéria hepática e da veia porta pela lesão.Comentários: A icteríciafreqüentemente acontece como manifestação tardia dos LNH, mas raramente como sinal clínico inicial. Nos casos em que a icterícia é primeira manifestação e os exames de imagem revelam obstrução de vias biliares e massa tumoral no hilo hepático, o LNH deve ser considerado no diagnóstico diferencial.
