Obstrução intestinal após uso de infliximab no tratamento de fístula êntero-cutânea na doença de Crohn

Crohn's disease is often complicated by the development of fistulas. Infliximab, a monoclonal antibody that binds tumor necrosis factor a have shown to be successful in the treatment of fistulizing Crohn's disease. It's possible complications and side effects have not been completely elucidated. Our objective is to report a case of a patient who developed intestinal obstruction after treatment of fistulizing Crohn's disease with infliximab. A 50 years-old female with Crohn's disease presented with spontaneous enterocutaneous fistula. She was successfully treated with the infusion of 5mg/kg infliximab at weeks 0, 2, and 6, with complete closure of the fistula after the first infusion. Eight weeks after treatment she developed small bowel obstruction secondary to stenosis of the ileum. She was subjected to exploratory laparotomy and resection of the stenotic ileum. The patient had good recovery, with no complications, and was discharged on the 5th postoperative day. Although a faster and complete healing of enterocutaneous fistula was induced by infliximab, this treatment may have caused intestinal obstruction in this case.

Técnicas hemoterápicas em cirurgia renal percutânea em paciente testemunha de Jeová

Jehova's witeness patients deny to receive heterologous blood transfusion even under life risk. They also neither agree with auto transfusion when the their own blood is stored days or weeks before surgery procedures. Percutaneous renal surgery can have complications and, among them, intense hemorrhage that can demand for open surgery. The authors report a case of a 32 year old patient with complete coralliform lithiasis in the right kidney who was submitted to percutaneous renal surgery with removing 400 ml of total blood accompanied subsequently of hemodilution and blood reinfusion by the end of the procedure. A Compact Advanced from Dideco, an italian company, was used for blood recovering during surgery and reinfusing it after the filtration process, centrifugation and washing of red globules. In this particular, the authors describe a technical adaption for blood collection. Both procedures are accepted by Jehova's witness patients, once that the blood is not stored and there is contact with your veined system. This article aim to show a blood capture technical variant in the percutaneous renal surgery, as well as to present a method in similar procedures, once that is not used routinely in urological surgeries.

Cardiorespiratory responses during and after water exercise in pregnant and non-pregnant women

PURPOSE: to compare the blood pressure and oxygen consumption (VO2) responses between pregnant and non-pregnant women, during cycle ergometer exercise on land and in water. METHODS: ten pregnant (27 to 29 weeks of gestation) and ten non-pregnant women were enrolled. Two cardiopulmonary tests were performed on a cycle ergometer (water and land) at the heart rate corresponding to VO2, over a period of 30 minutes each. Exercise measurements consisted of recording blood pressure every five minutes, and heart rate and VO2 every 20 seconds. Two-way ANOVA was used and α=0.05 (SPSS 17.0). RESULTS: there was no difference in cardiovascular responses between pregnant and non-pregnant women during the exercise. The Pregnant Group demonstrated significant differences in systolic (131.6±8.2; 142.6±11.3 mmHg), diastolic (64.8±5.9; 74.5±5.3 mmHg), and mean blood pressure (87.0±4.1; 97.2±5.7 mmHg), during water and land exercise, respectively. The Non-pregnant women Group also had a significantly lower systolic (130.5±8.4; 135.9±8.7 mmHg), diastolic (67.4±5.7; 69.0±10.1 mmHg), and mean blood pressure (88.4±4.8; 91.3±7.8 mmHg) during water exercise compared to the land one. There were no significant differences in VO2 values between water and land exercises or between pregnant and non-pregnant women. After the first five-minute recovery period, both blood pressure and VO2 were similar to pre-exercise values. CONCLUSIONS: for pregnant women with 27 to 29 weeks of gestation, water exercise at the heart rate corresponding to VO2 is physiologically appropriate. These women also present a lower blood pressure response to exercise in water than on land.

Sobrevida e morbidade em prematuros com menos de 32 semanas de gestação na região central do Brasil

OBJETIVO: Avaliar a sobrevida e complicações associadas à prematuridade em recém-nascidos com menos de 32 semanas. MÉTODOS: Estudo prospectivo do tipo coorte. Foram incluídos os nascidos vivos, com idade gestacional entre 25 semanas e 31 semanas e 6 dias, sem anomalias congênitas admitidos em UTI Neonatal, entre 1º de agosto de 2009 e 31 de outubro de 2010. Os recém-nascidos foram estratificados em três grupos: G25, 25 a 27 semanas e 6 dias; G28, 28 a 29 semanas e 6 dias; G30, 30 a 31 semanas e 6 dias, e acompanhados até 28 dias. Foram avaliadas a sobrevida aos 28 dias e a morbidade associadas à prematuridade. Para análise dos resultados, utilizou-se o teste do c², análise de variância, teste de Kruskal-Wallis, razão de risco com intervalo de confiança (IC) e regressão logística múltipla, com significância em 5%. RESULTADOS: A coorte compreendeu 198 prematuros, sendo G25=59, G28=43 e G30=96. O risco de óbito foi significativamente maior em G25 e G28, em relação ao G30 (RR=4,1; IC95% 2,2-7,6 e RR=2,8; IC95% 1,4-5,7). A sobrevida encontrada foi, respectivamente, 52,5, 67,4 e 88,5%. A partir da 26ª semana e peso >700 g, a sobrevida foi superior a 50%. A morbidade foi inversamente proporcional à idade gestacional, exceto para enterocolite necrosante e leucomalácia, que não diferiram entre os grupos. A análise de regressão logística mostrou que a hemorragia pulmonar (OR=3,3; IC95% 1,4-7,9) e a síndrome do desconforto respiratório (OR=2,5; IC95% 1,1-6,1) foram fatores independentes de risco para óbito. Houve predomínio das lesões cerebrais hemorrágicas graves em G25. CONCLUSÕES: Sobrevivência superior a 50% ocorreu a partir da 26ª semana de gravidez e peso >700 g. A hemorragia pulmonar e a síndrome do desconforto respiratório foram preditores independentes de óbito. Há necessidade de identificar e instituir práticas para melhorar a sobrevida de prematuros extremos.

Obstetric outcomes in the second birth of women with a previous caesarean delivery: a retrospective cohort study from Peru

PURPOSE: To examine obstetric outcomes in the second birth of women who had undergone a previous cesarean delivery. METHODS: This was a large hospital-based retrospective cohort study. We included pregnant women who had a previous delivery (vaginal or cesarean) attending their second birth from 2001 to 2009. Main inclusion criteria were singleton pregnancies and delivery between a gestation of 24 and 41 weeks. Two cohorts were selected, being women with a previous cesarean delivery (n=7,215) and those with a vaginal one (n=23,720). Both groups were compared and logistic regression was performed to adjust for confounding variables. The obstetric outcomes included uterine rupture, placenta previa, and placental-related complications such as placental abruption, preeclampsia, and spontaneous preterm delivery. RESULTS: Women with previous cesarean delivery were more likely to have adverse outcomes such as uterine rupture (OR=12.4, 95%CI 6.8-22.3), placental abruption (OR=1.4, 95%CI 1.1-2.1), preeclampsia (OR=1.4, 95%CI 1.2-1.6), and spontaneous preterm delivery (OR=1.4, 95%CI 1.1-1.7). CONCLUSIONS: Individuals with previous cesarean section have adverse obstetric outcomes in the subsequent pregnancy, including uterine rupture, and placental-related disorders such as preeclampsia, spontaneous preterm delivery, and placental abruption.

Chromosomal abnormalities in couples with recurrent first trimester abortions

PURPOSE: To investigate the prevalence of chromosomal abnormalities in couples with two or more recurrent first trimester miscarriages of unknown cause. METHODS: The study was conducted on 151 women and 94 partners who had an obstetrical history of two or more consecutive first trimester abortions (1-12 weeks of gestation). The controls were 100 healthy women without a history of pregnancy loss. Chromosomal analysis was performed on peripheral blood lymphocytes cultured for 72 hours, using Trypsin-Giemsa (GTG) banding. In all cases, at least 30 metaphases were analyzed and 2 karyotypes were prepared, using light microscopy. The statistical analysis was performed using the Student t-test for normally distributed data and the Mann-Whitney test for non-parametric data. The Kruskal-Wallis test or Analysis of Variance was used to compare the mean values between three or more groups. The software used was Statistical Package for the Social Sciences (SPSS), version 17.0. RESULTS: The frequency of chromosomal abnormalities in women with recurrent miscarriages was 7.3%, including 4.7% with X-chromosome mosaicism, 2% with reciprocal translocations and 0.6% with Robertsonian translocations. A total of 2.1% of the partners of women with recurrent miscarriages had chromosomal abnormalities, including 1% with X-chromosome mosaicism and 1% with inversions. Among the controls, 1% had mosaicism. CONCLUSION: An association between chromosomal abnormalities and recurrent miscarriage in the first trimester of pregnancy (OR=7.7; 95%CI 1.2--170.5) was observed in the present study. Etiologic identification of genetic factors represents important clinical information for genetic counseling and orientation of the couple about the risk for future pregnancies and decreases the number of investigations needed to elucidate the possible causes of miscarriages.

Mondor's disease in puerperium: case report

Mondor's disease is a rare entity characterized by sclerosing thrombophlebitis classically involving one or more of the subcutaneous veins of the breast and anterior chest wall. It is usually a self-limited, benign condition, despite of rare cases of association to cancer. We present the case of a 32 year-old female, breast-feeding, who went to emergency due to left mastalgia for the past week. She was taking antibiotics and non-steroidal anti-inflammatory drugs, previously prescribed for suspicious of mastitis, for three days, with no clinical improvement. Physical examination showed an enlarged left breast, an axillary lump and a painful cord-like structure in the upper outer quadrant of the same breast. Ultrasound scan showed a markedly dilated superficial vein in the upper outer quadrant of left breast. The patient was given a ventropic therapy and was kept in anti-inflammatory, with progressive pain improvement. Ultrasound control was performed after four weeks, showing reperfusion.

Spontaneous rupture of renal angiomyolipoma during pregnancy

Renal angiomyolipoma is a benign tumor, composed of adipocytes, smooth muscle cells and blood vessels. The association with pregnancy is rare and related with an increased risk of complications, including rupture with massive retroperitoneal hemorrhage. The follow-up is controversial because of the lack of known cases, but the priorities are: timely diagnosis in urgent cases and a conservative treatment when possible. The mode of delivery is not consensual and should be individualized to each case. We report a case of a pregnant woman with 18 weeks of gestation admitted in the emergency room with an acute right low back pain with no other symptoms. The diagnosis of rupture of renal angiomyolipoma was established by ultrasound and, due to hemodinamically stability, conservative treatment with imaging and clinical monitoring was chosen. At 35 weeks of gestation, it was performed elective cesarean section without complications for both mother and fetus.

Reproductive outcome in pregnant women with recurrent pregnancy loss

Abstract PURPOSE: To estimate the future pregnancy success rate in women with a history of recurrent pregnancy loss. METHODS: A retrospective cohort study including 103 women seen at a clinic for recurrent pregnancy loss (loss group) between January 2006 and December 2010 and a control group including 204 pregnant women seen at a low-risk prenatal care unit between May 2007 and April 2008. Both groups were seen in the university teaching hospital the Maternidade Climério de Oliveira, Salvador, Bahia, Brazil. Reproductive success rate was defined as an alive-birth, independent of gestational age at birth and survival after the neonatal period. Continuous variables Means and standard deviations (SD) were compared using Student's t-test and nominal variables proportions by Pearson χ2test. RESULTS: Out of 90 who conceived, 83 (91.2%) had reproductive success rate. There were more full-term pregnancies in the control than in the loss group (174/187; 92.1 versus 51/90; 56.7%; p<0.01). The prenatal visits number was satisfactory for 76 (85.4%) women in the loss group and 125 (61.3%) in the control (p<0.01). In this, the beginning of prenatal care was earlier (13.3; 4.2 versus 19.6; 6.9 weeks). During pregnancy, the loss group women increased the weight more than those in the control group (58.1 versus 46.6%; p=0.04). Although cervix cerclage was performed in 32/90 women in the loss group, the pregnancy duration mean was smaller (34.8 weeks; SD=5.6 versus 39.3 weeks; SD=1.6; p<0.01) than in the control group. Due to gestational complications, cesarean delivery predominated in the loss group (55/83; 64.7 versus 73/183; 39.5%; p<0.01). CONCLUSION: A very good reproductive success rate can be attributed to greater availability of healthcare services to receive pregnant women, through prenatal visits (scheduled or not), cervical cerclage performed on time, and available hospital care for the mother and newborn.

Field evaluation of safety during gestation and horizontal spread of a recombinant differential bovine herpesvirus 1 (BoHV-1) vaccine

Bovine herpesvirus type 1 (BoHV-1) is recognized as a major cause of respiratory, reproductive disease and abortion in cattle. Vaccination is widely applied to minimize losses induced by BoHV-1 infections; however, vaccination of dams during pregnancy with modified live virus (MLV) vaccines has been occasionally associated to abortions. We have previously reported the development of a BoHV-1 recombinant virus, constructed with basis on a Brazilian BoHV-1 (Franco et al. 2002a) from which the gene coding for glycoprotein E (gE) was deleted (gE-) by genetic manipulation. Such recombinant has been previously evaluated in its potential as a differential vaccine (gE- vaccine) that allows differentiation between vaccinated and infected animals. Here, in the first part of the present study, the safety of the gE- vaccine during pregnancy was evaluated by the intramuscular inoculation of 10(7.4) tissue culture 50 % infective doses (TCID50) of the virus into 22 pregnant dams (14 BoHV-1 seronegative; 8 seropositive), at different stages of gestation. Other 15 pregnant dams were kept as non-vaccinated controls. No abortions, stillbirths or fetal abnormalities were seen after vaccination. Seroconversion was observed in both groups of previously seronegative vaccinated animals. In the second part of the study, the potential of the gE- vaccine virus to spread among beef cattle under field conditions was examined. Four heifers were inoculated intranasally with a larger amount (10(7,6) TCID50) of the gE- vaccine (to increase chances of transmission) and mixed with other sixteen animals at the same age and body condition, in the same grazing area, at a population density equal to the average cattle farming density within the region (one cattle head per 10,000 m²), for 180 days. All animals were monitored daily for clinical signs. Serum samples were collected on days 0, 30, 60 and 180 post-vaccination. Seroconversion was observed only in vaccinated heifers. These results indicate that, under the conditions of the present study, the gE- vaccine virus did not cause any noticeable harmful effect on pregnant dams and on its offspring and did not spread horizontally among cattle.

The materno-fetal interface in llama (Lama guanicoe glama)

Samples from 9 llamas (28 through 36 weeks of gestation) were collected and fixed in 4% buffered paraformaldehyde (light microscopy) and in 2.5% buffered glutaraldehyde (transmission and scanning electron microscopy). The material was processed in paraplast and slides (5mm) were stained with HE, PAS, Masson-Trichrome, acid phosphatase and Perl's. The uteroferrin was immunolocalized. The results show that llama placenta is chorioallantoic, diffuse, folded and epitheliochorial, and the fetus is covered with an epidermal membrane. The trophoblast cells have variable morphology: cubic, rounded and triangular cells, with cytoplasm containing PAS-positive granules. Binucleated cells with large cytoplasm and rounded nuclei, as well as giant trophoblastic cells with multiple nuclei were also observed. Numerous blood vessels were observed beneath the cells of the uterine epithelium and around the chorionic subdivided branches. Glandular activity was shown by PAS, Perl's, and acid phosphatase positive reactions in the cytoplasm and glandular lumen, and by immunolocalization of the uteroferrin in the glandular epithelium. The uterine glands open in spaces formed by the areoles, which are filled by PAS-positive material. The llama fetus was covered by the epidermal membrane, composed of stratified epithelium, with up to seven layers of mono-, bi- or trinucleated cells. The high level of maternal and fetal vascularization surfaces indicates an intense exchange of substances across both surfaces. The metabolic activity shown in the uterine glands suggests an adaptation of the gestation to the high altitudes of the natural habitat of this species.
