Perfil hematológico de Chelonia mydas (Testudines, Cheloniidae) de acordo com o grau de acometimento pela fibropapilomatose e sua ausência

The green turtle Chelonia mydas feeds and nests in the Brazilian coastal area and is considered an endangered species by the World Conservation Union (IUCN 2009) and threatened by the Red List of Brazilian Fauna (Ministério do Meio Ambiente 2009). Fibropapillomatosis is a disease characterized by benign skin tumors (fibropapillomas), and it is one of the main threats to the survival of this species. Studies suggest the involvement of viruses as infectious agents associated with environmental and genetic factors. Blood samples were collected from 45 turtles captured in the coastal area of the state of Sao Paulo, Brazil. From these, 27 were affected by fibropapillomas and 18 were tumor free. Biometrical data on the turtles, size, location and quantity of tumors were recorded. The area occupied by fibropapillomas per animal was calculated and four groups were determined according to severity of the disease or its absence. The objective of the study was to compare hemogram results of the sea turtles classified in these four groups. The lowest hematocrit value was observed in severely affected animals. In the hemoglobin assay, the highest value was observed in the group of tumor free turtles and the lowest, in animals severely affected. Lymphocyte counts and curved carapace length were on the verge of statistical significance.Chelonia mydas, denominada tartaruga verde, é uma tartaruga marinha que frequenta o litoral brasileiro para alimentação e nidificação e é considerada em perigo de extinção pela IUCN (World Conservation Union, 2009) e ameaçada pela Lista Vermelha da Fauna Brasileira (Ministério do Meio Ambiente, 2009). A fibropapilomatose, doença caracterizada por tumores cutâneos benignos (fibropapilomas), é uma das mais importantes ameaças à sobrevivência dessa espécie. Pesquisas sugerem o envolvimento de agentes infecciosos virais em associação com fatores ambientais e genéticos. Foram colhidas amostras sanguíneas de 45 tartarugas provenientes do litoral do estado de São Paulo, Brasil, sendo 18 sem fibropapilomas e 27 acometidas. Dados de biometria das tartarugas, quantidade, localização e tamanho dos tumores foram anotados. Foi realizado o cálculo da área de fibropapilomas por animal e foram estipulados 4 grupos de acordo com o grau de acometimento e sua ausência. O objetivo foi realizar uma comparação entre os hemogramas das tartarugas marinhas classificadas nos 4 grupos. Animais de grau grave apresentaram o menor valor para hematócrito. Para dosagem de hemoglobina, observou-se que o maior valor foi para o grupo de tartarugas sem fibropapilomas e o menor para o de grau grave. Os valores de linfócitos e comprimento curvilíneo da carapaça beiraram a significância estatística

Larva migrans cutânea em crianças de uma escola em área do Centro-Oeste do Brasil

This paper reports an outbreak of cutaneous larva migrans in children of a school located in Campo Grande, MS. Six out of the 16 students (37.5%) acquired this parasitic dermatitis in two playgrounds contaminated by cat feces, in which ancylostomid larvae were found. The serpiginous lesions and/or papules were located in the hands, feet, buttocks, thighs, vulva and scrotum. Control measures of this parasitosis are discussed.Relata-se a ocorrência de larva migrans cutânea em crianças de uma escola de educação infantil de Campo Grande, MS (Brasil). Dos 16 alunos que freqüentam a escola, seis (37,5%) adquiriram essa dermatite parasitária em duas áreas de recreação com areia contaminada por fezes de gatos, cujo exame parasitológico revelou a presença de larvas de ancilostomídeos. As lesões serpiginosas e/ou papulares essavam localizadas nas mãos, pés, nádegas, coxas, vulva e saco escrotal. São discutidas medidas de controle dessa parasitose

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Olive Ridley Sea Turtle Lepidochelys olivacea (Eschscholtz, 1829) from Brazil as a new host of Pyelosomum cochlear Looss 1899 (Digenea: Pronocephalidae)

Here we present the occurrence of Pyelosomum cochlear Looss 1899 in the urinary bladder of an olive ridley sea turtle Lepidochelys olivacea (Eschscholtz, 1829) from Brazil. This parasite species has previously been reported only from Chelonia mydas from Egypt, the United States (including Puerto Rico), Panama, and Costa Rica. This paper reports the first occurrence of P. cochlear parasitizing L. olivacea and the first occurrence of this parasite in the western South Atlantic

Hematological and histopathological evaluation of wildlife green turtles (Chelonia mydas) with and without fibropapilloma from the north coast of São Paulo State, Brazil

Blood profiles were determined in 47 juvenile green turtles, Chelonia mydas, from São Paulo northern coast, Brazil. Twenty-nine were affected by fibropapillomas and 18 were tumor free. Complete gross and histopathologic examinations of the fibropapillo were performed in 21 green turtles. Biometrical data, size, location and amount of tumors were recorded. The papillomas varied in morphology, location, size, color and texture. We found hyperplastic stroma, rich in blood vessels and connective tissue with increase in thickness of the dermis. The tumors w0ere classified as papillomas or fibropapillomas according to their epithelial and/or stromal proliferation. The lowest Mean Corpuscular Hemoglobin (HCM) values were observed in affected turtles
