Objective: To assess the role of early prophylaxis with recombinant activated factor VII (rFVIIa) in young haemophiliacs with inhibitors and to determine whether it can reduce bleeding episodes and prevent joint damage. Patients and Methods: Ten severe haemophiliacs, less of three years old, with up to four joint bleeds and inhibitors to FVIII who started early prophylaxis with rFVIIa, were included. A number of haemorrhages/year/patient and haemarthroses/ year/patient were compared before the start of prophylaxis, which include both the time before (initial period) and after inhibitor diagnosis (inhibitor period), with those during prophylaxis (prophylaxis period). Results: The mean time of inhibitor diagnosis was 15.6 months (range: 2.3-34.1). The mean time between inhibitor diagnosis and the start of prophylaxis was 7.1 months (range: 0-23.2), shorter than the time of rFVIIa prophylaxis (mean: 10.3 months;range: 4.1-32.0). Bleeding episodes for the three time periods were 45, 36 and 17, respectively, or 0.29 and 0.51 haemorrhages/year/patient in the two periods prior to prophylaxis compared to 0.17 during prophylaxis. Total haemarthroses for the three-time periods were 7, 5 and 5, respectively. The haemarthroses/year/patient in the pre-prophylaxis period were 0.032 and 0.070, compared to0.049 inthe prophylaxis period. rFVIIa schedules were either 90 μg/kg three times weekly or 90 μg/kg daily. Conclusions: early prophylaxis with rFVIIa may be efficacious in young haemophiliacs with inhibitors, reducing joint bleeds. After the risky period of inhibitor presence, they are able to continue rFVIII prophylaxis with success assured to prevent arthropathy.

Actinic cheilitis can progress to squamous cell carcinoma in 20% of cases. The purpose of this study was to identify the clinical characteristics of 75 patients with actinic cheilitis and to summarise the current literature concerning actinic cheilitis. A total of 75 patients were evaluated over a 3-year period. The medical history, physical examination results and images were collected from each patient. Demographic data were collected and analysed. To review the literature, the relevant data were collected from scientific journals in the last 30 years. The mean age of the patients was 56 years old;42 patients (56%) were female, and 66 patients (88%) were white. Nineteen (25.3%) patients reported at least one symptom, including pain, burning and itching. Sixty-five (86.7%) patients presented actinic cheilitis only in the lower lip. All of the patients reported sun exposure, and 44 (58.6%) patients were exposed for more than 10 years. The main clinical aspects investigated and analysed included dryness (100%), flaking (72%) and white lesions (57.3%). Lip assessment is extremely important in medical and dental care. From the 15 lesions assessed in the presence of actinic cheilitis, the most common clinical characteristics observed were dryness, flaking and white lesions. It is imperative to know the clinical aspects that may be encountered in actinic cheilitis in order to achieve early diagnosis, thus avoiding lip squamous cell carcinoma transformation.

Peri-intraventricular hemorrhage is one of the main causes of neurological impairment in premature newborns. To control their risk factors is necessary in view of the increasing survival of extreme preterm infants. Objective: To evaluate the prevalence of peri-intraventricular hemorrhage in premature newborns, identify the risk factors and observe the frequencies of intra-hospital outcomes of interests. Methods: This study was done in Brazil. This was an observational, analytical longitudinal and prospective study. The subjects included were newborns of gestational age less than 34 weeks who were admitted to two public hospitals between May and November 2015.

Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However,its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions,emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man,40 years old,with no medical history,with abdominal discomfort and progressive fatigue,presented four months ago with one episode o f m o d e ra t e m e l e n a. T h e p hy s i c a l e x a m i n a t i o n was normal,except for mucosal pallor. Blood tests were consistent with microcytic,hypochromic iron deficiency anemia with 7.8 g/d L hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions o f t h e d u o d e n u m. B i o p s y s h o w e d a m o d e ra t e l y differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum,without distant metastasis. The patient underwent segmental resection(distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis,with transmural infiltration,without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value.

This study aimed to describe structure, functionality and development of pediatric heart transplant families, from the understanding of the experienced chronic condition. A descriptive, exploratory study using a qualitative approach was developed in a hospital situated in a city of Northeast Brazil, in 2012. The study was conducted with three families, using the Calgary Family Assessment Model (CFAM). In addition to the genogram, an analysis of the children’s/adolescents’ family members was conducted at the time of interview. Two families were binuclear families and one was mononuclear. From the evaluation, it was possible to determine the care and support network of children and adolescents with heart transplants, as well as some difficulties faced by the investigated families. Nurses are important in this family context since the visualization of the family genogram can generate a change in the nursing care to each family.

Mangroves perform essential functions in biological cycles and are protected by law in Brazil. However, they are being degraded above their support limit, leading to a reduction in the areas around the world. The area investigated in the present study is a potentially unpolluted mangrove ecosystem in the south of Rio de Janeiro state, Brazil. The aim of this work was to investigate the presence of metals and polycyclic aromatic hydrocarbons (PAHs) in mangrove sediment and to correlate them with mutagenic and genotoxic activity. Four seasonal samplings undertaken between 2009 and 2010 at five sites were analyzed. Dichloromethane extracts were obtained under sonication and subjected to mutagenicity assays using Salmonella microsuspension. Metal (Cd, Cr, Cu, Ni and Pb) contents were determined by atomic absorption spectrometry, while the quantification of PAHs was performed by gas chromatography-mass spectrometry. Goniopsis cruentata hemocytes were used to assess potential genotoxic damage (Micronucleus assay). The absence of mutagenicity was observed for all samples using Salmonella typhimurium strains TA97, TA98, TA100 and TA102, in the absence and presence of an exogenous mammalian metabolizing system. Among the metals, Cd and Cu were detected in autumn at values exceeding the threshold effect level and below the probable effect level. Benzo[a] pyrene was detected at levels above the threshold at one site, where small effects could be observed in the biota. Significant differences in the micronucleated cells observed suggest DNA damage had been induced by the PAHs identified.
