RESUMEN

INTRODUCTION AND IMPORTANCE: The parasitic fetus is a kind of siamese twin, in which one of the twins is reabsorbed and some parts of the body can remain attached to the other twin. It is a very rare event, with a birth incidence that varies from 0.05 to 1.47 cases per 100,000. CASE PRESENTATION: This paper reports the case of a parasitic twin diagnosed at 34 weeks of gestational age. Preoperative ultrasonography was performed and the absence of communication between vital organs and the parasite was observed, and surgery was scheduled at 10 days of life. A multidisciplinary team performed the surgical procedure and the child was discharged from the intensive care unit after 3 months. CLINICAL DISCUSSION: After diagnosis and birth, it is essential to investigate the anomalies found for future surgical programming, and cases of twins who do not share vital organs, for example, heart or brain, have higher survival rates. The treatment is surgical and the objective of the surgery must be resection of the parasite. CONCLUSION: The diagnosis still in the gestational period is essential to plan the best mode of delivery and neonatal care, as well as define the surgical schedule. The hospital must be tertiary and the presence of a multidisciplinary team is necessary to perform the surgery in order to present the highest success rates.

RESUMEN

INTRODUCTION: Kaposiform hemangioendothelioma is a rare tumor, of vascular origin, which predominates in childhood. Although it is frequently a vascular cutaneous anomaly, it is known that some cases can involve bones, mediastinum and retroperitoneum, being even rarer when it occurs in the small intestine, representing only 0.05% of all intestinal neoplasms. PRESENTATION OF CASE: Female patient, 21 days old, born at 38 weeks, is admitted to the hospital due to bilious vomiting, dehydration and major abdominal distension. An X-ray of the acute abdomen suggests type I jejunal atresia. An exploratory laparotomy was performed, with the presence of a stenotic area in the proximal jejunum, which was chosen for resection of the stenotic area and end-to-end terminal anastomosis, with post-pyloric jejunostomy. The presence of kaposiform hemangioma was confirmed by immunohistochemistry, and the patient had no further complications. DISCUSSION: The presence of hemangiomas in childhood is frequent, is but it very rare when it appears in the gastrointestinal location, as reported in the present case. A common presentation is intestinal bleeding, being manifested as anemia or, sometimes, acute and potentially fatal anemia. Other forms of rare presentation include intussusception, perforation and obstruction, the latter being out patient's last manifestation. The diagnosis of this alteration can be difficult, and often performed only in the intraoperative period of an exploratory laparotomy. CONCLUSION: The presence of bilateral vomiting and intestinal obstruction in newborns opens the possibility of a wide range of possible diagnoses, such as the presence of intestinal atresia. Kaposiform intestinal hemangioma is an uncommon cause in these clinical manifestations, but it should be included in the differential diagnosis.

RESUMEN

OBJECTIVE: to evaluate the knowledge growth of the members of the Trauma, Resuscitation and Emergency League in comparison with a nonparticipating group, with similar characteristics, at the Fluminense Federal University. METHODS: we evaluated 50 league members and 50 non-members (control group) through questionnaires applied at the beginning and end of a school year. We used a generalized linear model, with interaction effect between groups and tests (multiple comparisons with Bonferroni correction). We included the following control variables: gender, period, age, and attendance to some other course on a similar topic. RESULTS: there was an increase of 22 percentage points (p<0.001) for the group with more than 75% presence in the League compared with the eight points in the control group (p<0.05). There was no statistically significant growth for the group with less than 75% presence. CONCLUSION: the growth of knowledge was significantly higher in the group that assiduously participated in the League, which reinforces its importance in complementing the traditional content of medical courses.

RESUMEN

The aim of this work was to study effect of the dry matter intake level on the concentrations of glucose, insulin, urea, estrogen and progesterone in the blood and the level of IGF-I in the follicular liquid of heifers. Twenty seven crossbred heifers were used, in three treatments: 1.2, 1.6 and 2.6 percent of the live weight of dry matter intake (DMI) daily. The sanguine concentrations of glucose and estrogen were higher in the animals with 1.6 percent of DMI and the insulin levels were higher in the animals with 2.6 percent of DMI. There was an increase in the sanguine levels of urea with the increase of the DMI. There was no effect of the DMI on the progesterone levels in the sanguine plasma collected from the jugular. The progesterone levels in caudal vena were higher in the animals with 2.6 percent of DMI. There was no effect of the DMI on the follicular levels of IGF-I.

O objetivo deste trabalho foi estudar o efeito do nível de ingestão de matéria seca (IMS/ por cento do PV) sobre as concentrações sanguíneas de glicose, insulina, urea, estrógeno e progesterona e o nível de IGF-I no líquido folicular de novilhas. Vinte e sete novilhas cruzadas foram utilizadas, distribuídas em três tratamentos: 1,2 por cento; 1,6 por cento e 2,6 por cento do peso vivo de ingestão de matéria seca por dia. As concentrações no plasma da veia jugular de glicose e estrógeno foram maiores nos animais com 1,6 por cento de IMS e os níveis de insulina foram maiores nos animais com 2,6 por cento de IMS. Houve um aumento dos níveis plasmáticos de uréia com aumento dos níveis de IMS. Não houve efeito da IMS sobre os níveis de progesterona no plasma sangüíneo coletado da jugular. No plasma sangüíneo coletado da veia cada caudal, os níveis de progesterona foram maiores (P<0,05) nos animais com 2,6 por cento de IMS. Não houve efeito da IMS sobre os níveis foliculares de IGF-I.

RESUMEN

A experimento foi realizado no Setor de Bovinocultura de Leite da Fazenda Experimental de Iguatemi, Maringá, Paraná, com o objetivo de avaliar o efeito do uso de probióticos sobre o índice de diarréia, mortalidade e desempenho (altura e peso) de bezerros. As mediçöes de peso e altura foram feitas logo após o nascimento dos animais, aos 30 e aos 60 dias de idade. Foram utilizados 19 bezerros puros por cruza Holandês, do nascimento aos 60 dias de idade, machos e fêmeas. Os bezerros foram distribuídos em três tratamentos: (A) leite integral + probiótico em pó solúvel, (B) leite integral + probiótico em pó solúvel e pasta probiótica de administraçäo oral e (C) leite integral. Foram fornecidos feno e concentrado à vontade após 20 dias de idade. Os índices de diarréia e mortalidade foram nulos para os três tratamentos. Näo houve diferença significativa para o ganho médio diário e mudança nas alturas tomadas nas cernelhas do nascimento aos 60 dias de idade entre os tratamentos A (0,56 kg/dia e 0,055 cm/dia), B (0,41 kg/dia e 0,075 cm/dia) e C (0,51 kg/dia e 0,043 cm/dia)
