RESUMO
Objective: Compare the number of puerperal women submitted to blood transfusion before and after the implementation of a care protocol for postpartum hemorrhage (PPH) with multidisciplinary team training. Methods: Cross-sectional study in a university hospital, analyzing births from 2015 to 2019, compared the use of blood products before and after the adoption of a PPH protocol with multidisciplinary training. Results: Between 2015 and 2019, there were 17,731 births, with 299 (1.7%) postpartum women receiving blood products and 278 postpartum women were considered for this analysis, 128 (0.7%) at Time 1 and 150 (0.8%) at Time 2. After the multiprofessional team training (T2), there was a difference in the complete use of the PPH protocol (use of oxytocin, misoprostol and tranexamic acid) (T1 = 5.1% x T2 = 49.5%, p≤0.0001). An individual categorized analysis revealed that, in the T2 period, there was lower use of blood component units per patient compared to T1 (Mann-Whitney, p=0.006). It should be noted that at T1 and T2, 54% and 24% respectively received two units of blood products. It is important to highlight that after the multidisciplinary team training for the PPH protocol, the goal of zero maternal death due to hemorrhage was reached. Conclusion: The adoption of a specific protocol for PPH, combined with the training of a multidisciplinary team, had an impact on the ability to identify women at high risk of hemorrhage, resulting in a decrease in the use of blood components.

RESUMO
OBJECTIVE: To describe a population of pregnant women diagnosed with toxoplasmosis and their respective newborns, describing the hospital protocol for treatment and follow-up. METHODS: Retrospective cohort of pregnant women with acute toxoplasmosis infection and risk of transplacental transmission who were sent to the Fetal Medicine Group of Hospital de Clínicas de Porto Alegre (HCPA) between - January 1, 2006 and December 31, 2016. All patients with confirmed disease were included. The diagnostic protocol and treatment were applied; a polymerase chain reaction (PCR) analysis of the amniotic fluid was used to diagnose toxoplasmosis and determine the treatment. The newborns were followed up at the pediatric outpatient clinic specializing in congenital infection. The patients who were not followed up or were not born in the HCPA were excluded. RESULTS: A total of 65 patients were confirmed to have gestational toxoplasmosis; 40 performed amniocentesis, and 6 (15%) were identified as having positive PCR in the amniotic fluid. In five of those cases, this result associated with the gestational age defined the triple therapy during pregnancy, and in one case, it defined the monotherapy (advanced gestational age). A total of 4 of these newborns were treated from birth with triple therapy for 10 months, 1 was not treated (due to maternal refusal), and 1 progressed to death within the first 54 hours of life due to complications of congenital toxoplasmosis. Of the 34 remaining cases with a negative PCR, 33 were treated with monotherapy and 1 was treated with triple therapy (ultrasound findings); of these children, 9 (26.5%) presented negative immunoglobulin G (IgG), 24 (70.6%) presented positive IgG (but none presented positive immunoglobulin M [IgM]), and 1 (2,9%) presented alterations compatible with congenital disease and started treatment with the triple therapy soon after birth. Out of the total sample of 60 patients, among the 25 who did not perform amniotic fluid PCR, 5 were treated with triple therapy (ultrasound findings/prior treatment) and 20 patients were submitted to monotherapy; only two newborns underwent treatment for congenital toxoplasmosis. Among the 65 cases of gestational toxoplasmosis, 6 (9,2%) children had a diagnosis of congenital toxoplasmosis, and 2 patients with triple therapy felt severe adverse effects of the medications. CONCLUSIONS: The present study suggests that research on PCR screening of the amniotic fluid may be useful to identify patients with a higher potential for fetal complications, who may benefit from the poly-antimicrobial treatment. Patients with negative PCR results must continue to prevent fetal infection with monotherapy, without risk of fetal or maternal impairment.
OBJETIVO: Descrever uma população de pacientes diagnosticadas com toxoplasmose na gestação e seus respectivos recém-nascidos, relatando o protocolo do hospital durante o tratamento e seguimento. MéTODOS: Coorte retrospectiva de gestantes com infecção aguda por toxoplasmose e risco de transmissão transplacentária, encaminhadas para acompanhamento pelo Grupo de Medicina Fetal do Hospital de Clínicas de Porto Alegre (HCPA) entre 1o de janeiro de 2006 e 31 de dezembro de 2016. Todas as pacientes com doença confirmada foram incluídas. O protocolo de diagnóstico e tratamento foi aplicado; uma análise da reação em cadeia da polimerase (RCP) no líquido amniótico foi utilizada para diagnosticar a toxoplasmose e determinar o tratamento. Os recém-nascidos foram acompanhados no ambulatório de pediatria especializado em infecções congênitas. Pacientes que não foram seguidas ou cujo parto não foi feito no hospital foram excluídas. RESULTADOS: A toxoplasmose gestacional foi confirmada em 65 pacientes; 40 realizaram amniocentese, e 6 (15%) foram identificadas com RCP positiva no líquido amniótico. Este resultado associado à idade gestacional definiu a terapia tríplice durante a gestação em 5 casos, e a monoterapia em 1 caso (por idade gestacional avançada). Quatro destas crianças foram tratadas desde o nascimento com terapia tríplice por 12 meses, 1 não foi tratada (por recusa materna), e 1 evoluiu com óbito dentro das primeiras 54 horas de vida devido a complicações da toxoplasmose congênita. Dos 34 casos remanescentes com RCP negativa, 33 foram tratados com monoterapia, e 1 foi tratado com terapia tríplice (por achados ultrassonográficos); destes recém-nascidos, 9 (26,5%) tiveram imunoglobulina G (IgG) negativa, 24 (70,6%) tiveram IgG positiva, mas nenhum apresentou imunoglobulina M (IgM) positiva, e 1 (2,9%) apresentou alterações compatíveis com doença congênita e iniciou a terapia tríplice logo após o nascimento. Entre as 25 pacientes que não fizeram RCP no líquido amniótico, 5 foram tratadas com terapia tríplice (por achados ultrassonográficos/tratamento prévio) e 20 receberam monoterapia; somente 2 recém-nascidos receberam tratamento para toxoplasmose congênita. Entre os 65 casos de toxoplasmose gestacional, 6 (9,2%) recém-nascidos tiveram o diagnóstico de toxoplasmose congênita. Um total de 2 pacientes submetidas à terapia tríplice apresentaram efeitos adversos severos das medicações utilizadas. CONCLUSãO: Este estudo sugere que a triagem da RCP para toxoplasmose do líquido amniótico pode ser útil no rastreamento de pacientes com maior potencial para complicações fetais, que podem se beneficiar do tratamento poli antimicrobiano. Pacientes com RCP negativa devem continuar a prevenir a infecção fetal com monoterapia, sem risco de comprometimento fetal ou materno.

Splenic artery aneurysm is a rare condition with a prevalence of less than 1% in the general population and is more common in women; however, it is the third most common cause of intra-abdominal aneurysms and the most common among visceral arterial aneurysms1. This condition was first described by Beussier in 1770; some of the risk factors often described are: fibrodysplasia, portal hypertension, splenomegaly, cirrhosis of the liver, liver transplant, pancreatitis, vasculitis, infectious mononucleosis, and pregnancy1-6.Pregnancy is considered the most important risk factor for the rupture of this aneurysm, but the true prevalence of this event is unknown2. Increased splanchnic and splenic circulation during pregnancy has been indicated as one of the main factors in the development of aneurysms. The modifications in circulation induced by estrogen and progesterone during pregnancy may also contribute to weakening blood vessel walls, especially at the bifurcations. It is speculated that the greater the womans parity the greater the risk of development and rupture of the aneurysm, due to the successive stresses to which the vessel wall is submitted3.The importance of an adequate diagnosis and management of this condition, despite its low prevalence, is supported by the high rates of maternal and fetal mortality, 75 and 95%, respectively3.

PURPOSE: To describe the prevalence of malformations found in fetuses with trisomy of chromosomes 13, 18 and 21 by identifying the most frequent within each condition. METHODS: A retrospective cross-sectional study with the analysis of trisomy cases of chromosomes 13, 18 and 21 diagnosed through fetal karyotype obtained by amniocentesis/cordocentesis, between October 1994 and May 2014, at a Teaching Hospital in Brazil Southern Region. Malformations identified through morphological ultrasonography were described and, subsequently, confirmed in newborn examinations and/or fetal autopsy. The results were analyzed using Fisher's test and analysis of variance (ANOVA), with a 5% level of significance (p=0.05). RESULTS: Sixty-nine cases of trisomy were diagnosed among 840 exams; nine were excluded due to outcome outside Hospital de Clínicas de Porto Alegre or incomplete records, remaining 60 cases (nine cases of chromosome 13 trisomy, 26 of chromosome 18, and 25 of chromosome 21). In all three groups, heart disease occurred in most cases; the ventricular septal defect was more prevalent and occurred in 66.7% of the trisomy 13 group. Gastrointestinal abnormalities were more prevalent in the trisomy 18 group, especially omphalocele (38.5%; p<0.01). Genitourinary anomalies were more significantly frequent in the trisomy 13 group (pyelectasis, 55.6% - p<0.01; ambiguous genitalia, 33.3% - p=0.01). Central nervous system defects were identified in all cases of trisomy 13. Facial cracks were significantly more prevalent among fetuses with trisomy 13 (66.7%; p<0.01). Hand and feet malformations significantly differed among the trisomy groups. Hand defects occurred in 50% of trisomy 18 cases, and in 44.4% of all trisomy 13 cases (p<0.01); congenital clubfoot was more common in the trisomy 18 group, being detected in 46.2% of fetuses (p<0.01). The abnormalities were found in 50.9, 27.3 and 21.7% of trisomy 18, 13 and 21 cases respectively. CONCLUSION: Many fetal malformations identified at ultrasound are suggestive of trisomy and represent an important tool for etiologic diagnosis and prenatal and pre-conception genetic counseling.

OBJETIVO: Descrever a prevalência das malformações encontradas nos fetos com trissomia dos cromossomos 13, 18 e 21, identificando as mais frequentes em cada condição. MÉTODOS: Estudo transversal retrospectivo, com análise dos casos de trissomias dos cromossomos 13, 18 e 21 que foram diagnosticados pelo cariótipo fetal obtido por amniocentese/cordocentese, entre outubro de 1994 e maio de 2014, em um Hospital de Ensino da região Sul do Brasil. Foram descritas as malformações identificadas no exame ultrassonográfico morfológico e, posteriormente, confirmadas em exames do recém-nascido e/ou por necropsia fetal. Os resultados foram analisados por meio do teste de Fisher e da análise de variância (ANOVA). O nível de significância empregado foi 5% (p=0,05). RESULTADOS: Em 840 exames realizados, foram diagnosticados 69 casos de trissomias; nove deles foram excluídos por desfecho ocorrido fora do Hospital de Clínicas de Porto Alegre ou prontuário incompleto, restando 60 casos (nove de trissomia do cromossomo 13, 26 do cromossomo 18 e 25 do cromossomo 21). As cardiopatias ocorreram, na maioria dos casos, nos três grupos; a comunicação interventricular foi mais prevalente, em 66,7% do grupo da trissomia 13. As anomalias gastrintestinais aconteceram mais no grupo da trissomia 18, principalmente a onfalocele (38,5%; p<0,01). As anomalias geniturinárias foram significativamente mais frequentes no grupo da trissomia 13 (pielectasia com 55,6% - p<0,01; genitália ambígua com 33,3% - p=0,01). Defeitos do sistema nervoso central foram identificados em todos os casos de trissomia 13. Fendas faciais foram mais prevalentes dentre os fetos com trissomia 13 (66,7%; p<0,01). Malformações nas mãos e nos pés tiveram diferenças estatísticas entre os grupos de trissomia. Os defeitos nas mãos ocorreram em 50% dos casos de trissomia 18 e em 44,4% dos casos de 13 (p<0,01); pé torto congênito foi mais comum no grupo da trissomia 18, descrito em 46,2% dos ...

Placental mesenchymal dysplasia (PMD) is a rare placental abnormality. We report a case of PMD associated with intrauterine growth restriction (IUGR), which was diagnosed by an ultrasound scan during the second trimester of pregnancy. A 36-year-old primiparous woman with signs of placental chorioangioma was referred to our hospital at the 23th gestational week. An ultrasonography revealed a small-for-gestational-age fetus with a large multicystic placenta. A serial Doppler sonographic assessment of umbilical and uterine artery blood flow showed a compromised fetus. A female, small-for-gestational-age baby was delivered by c-section at 28 weeks, and PMD was histopathologically confirmed

OBJETIVO: Analisar a taxa de mortalidade perinatal dos casos de gastrosquise e os possíveis fatores associados. MÉTODOS: Foi realizado estudo de coorte retrospectivo entre 1992 e 2012. Foram incluídos todos os casos de gastrosquise nascidos no Hospital de Clínicas de Porto Alegre (HCPA) naquele período. O diagnóstico de gastrosquise foi obtido por meio do exame ultrassonográfico morfológico ou pelo exame clínico ao nascimento nos casos desconhecidos no pré-natal. As variáveis de nascimento (peso ao nascer, idade gestacional e escore de Apgar, modo de parto, tipo de gastrosquise e anomalias associadas) e cirúrgicas (tipo de fechamento cirúrgico, reintervenção e sepse) foram comparadas entre os casos sobreviventes e os óbitos. Os resultados desta comparação foram analisados de acordo com o tipo de variável por meio de testes paramétricos e não paramétricos (Mann-Whitney ou teste t de Student, χ² ou teste exato de Fisher) sendo considerado o nível de significância de 5% (p=0,05). RESULTADOS: Foram incluídos 64 recém-nascidos com gastrosquise, 59 deles (92,2%) diagnosticados durante o pré-natal. Vinte e seis casos (40,6%) tinham somente intestino exposto, classificados como gastrosquise simples, 22 tinham intestino e estômago (34,4%) e 16 tinham intestino e outros órgãos (25%), totalizando 38 casos de gastrosquise complexa. O reparo cirúrgico primário foi realizado em 44 casos (68,8%). A mortalidade foi de 23,4% (15 mortes). Os casos de óbito tinham peso ao nascer (p=0,001), escore de Apgar (p=0,03) e idade gestacional (p=0,03) significativamente menores que os sobreviventes. Não houve diferença no modo de parto (p=0,8) e, com relação ao conteúdo eviscerado, não houve diferença entre os casos de gastrosquise simples e complexa (p=0,06). A mortalidade foi significativamente mais elevada entre os casos que necessitaram de reintervenção (p=0,001) e com sepse (p=0,008). CONCLUSÃO: A mortalidade perinatal da gastrosquise parece depender principalmente da prematuridade, baixo peso e complicações cirúrgicas.
PURPOSE: To analyze the perinatal mortality rate in cases of gastroschisis and possible associated factors. METHODS: A retrospective cohort study was conducted between 1992 and 2012. All cases of gastroschisis born in Hospital de Clínicas de Porto Alegre (HCPA) during that period were included. The diagnosis of gastroschisis was obtained by morphological ultrasound examination or clinical examination at birth in prenatally unknown cases. The variables of birth (birthweight, gestational age and Apgar score, mode of delivery, type of gastroschisis and associated anomalies) and the surgical ones (type of surgical closure, reintervention and sepsis) were compared between surviving cases and deaths. The results of this comparison were analyzed according to the type of variable using parametric and non-parametric tests (Mann-Whitney or Student's t-test, χ² or Fisher's exact test), with the level of significance set at 5% (p=0.05). RESULTS: Sixty-four newborns with gastroschisis were included, 59 of them (92.2%) diagnosed during the prenatal period. Twenty-six patients (40.6%) had only exposed intestines, classified as simple gastroschisis, 22 had exposure of the intestines and stomach (34.4%) and 16 had exposure of the intestine and other organs (25%), for a total of 38 cases of complex gastroschisis. Primary surgical repair was performed in 44 cases (68.8%). The mortality rate was 23.4% (15 deaths). Babies who died had significantly lower birth weight (p=0.001), gestational age (p=0.03) and Apgar score (p=0.03) than survivors. There was no difference in mode of delivery (p=0.8) and, with respect to gut contents, there was no difference between the cases of simple and complex gastroschisis (p=0.06). Mortality was significantly higher in patients with sepsis (p=0.008) and reintervention (p=0.001). CONCLUSION: in the present study, perinatal mortality due to gastroschisis seemed to depend mainly on prematurity, low birth weight, and surgical complications.

PURPOSE: To identify the etiology of nonimmune hydrops fetalis cases in pregnant women diagnosed and referred for prenatal care. METHODS: Retrospective analysis of cases with nonimmune hydrops fetalis that were monitored between March 1992 and December 2011. Diagnosis was confirmed by the presence of fetal subcutaneous edema (≥ 5 mm) with effusion in at least one serous cavity using obstetric ultrasound, and etiological investigation was conducted with cytogenetic (karyotype), infectious (syphilis, parvovirus B19, toxoplasmosis, rubella, cytomegalovirus, adenovirus and herpes simplex), hematologic and metabolic (inborn errors) analysis and fetal echocardiography. Twin pregnancies were excluded. Statistical analysis was performed using the χ² test for adhesion (software R 2.11.1). RESULTS: We included 116 patients with nonimmune hydrops fetalis; the etiology was elucidated in 91 cases (78.5%), while 25 cases (21.5%) were classified as idiopathic. Most cases had a chromosomal etiology, for a total of 26 cases (22.4%), followed by lymphatic etiology with 15 cases (12.9% with 11 cases of cystic hygroma), and cardiovascular and infectious etiology with 14 cases each (12.1%). In the remaining cases, the etiology was thoracic in 6.9% (eight cases), malformation syndromes in 4.3% (five cases), extrathoracic tumors in 3.4% (four cases), metabolic in 1.7% (two cases), and hematologic, gastrointestinal and genitourinary in 0.9% (one case each). During the postnatal period, 104 cases were followed up until the 40th day of life, and 12 cases had intrauterine fetal death. The survival rate of these 104 newborns was 23.1% (24 survived). CONCLUSION: An attempt should be made to clarify the etiology of hydrops diagnosed during pregnancy since the condition is associated with a wide spectrum of diseases. It is especially important to determine whether a potentially treatable condition is present and to identify disease at risk for recurrence in future pregnancies for adequate pre-conception counseling.

OBJETIVO: Identificar a etiologia da hidropisia fetal não imune em gestantes diagnosticadas e encaminhadas para acompanhamento pré-natal. MÉTODOS: Estudo retrospectivo com análise dos casos de hidropisia fetal não imune que foram acompanhados entre março de 1992 e dezembro de 2011. Os casos tiveram confirmação diagnóstica pela presença de edema de subcutâneo fetal (≥5 mm) com derrame em pelo menos uma cavidade serosa por meio da ultrassonografia obstétrica, e a investigação etiológica foi realizada com pesquisa citogenética (cariótipo), infecciosa (sífilis, parvovírus B19, toxoplasmose, rubéola, citomegalovírus, adenovírus e herpes simples), hematológica e metabólica (erros inatos), além de com ecocardiografia fetal. Foram excluídas as gestações gemelares. A análise estatística foi efetuada pelo teste do χ² para aderência (software R 2.11.1). RESULTADOS: Foram incluídas 116 pacientes com hidropisia fetal não imune, sendo que 91 casos (78,5%) tiveram a etiologia elucidada e 25 casos (21,5%) foram classificados como causa idiopática. A etiologia cromossômica foi a que apresentou maior número de casos, totalizando 26 (22,4%), seguida da etiologia linfática com 15 casos (12,9%, sendo 11 casos de higroma cístico), da etiologia cardiovascular e da infecciosa com 14 casos cada (12,1%). Os demais casos tiveram etiologia torácica em 6,9% (oito casos), síndromes malformativas em 4,3% (cinco casos), tumores extratorácicos em 3,4% (quatro casos), metabólica em 1,7% (dois casos), hematológica, gastrintestinal e geniturinária em 0,9% cada (um caso cada). No período pós-natal, foram seguidos 104 casos por até 40 dias de vida, 12 casos tiveram morte fetal intrauterina. A sobrevida desses 104 recém-nascidos foi de 23,1% (24 sobreviveram). CONCLUSÃO: a etiologia da hidropisia diagnosticada na gestação deve tentar ser esclarecida, uma vez que está associada a um amplo espectro de doenças. É especialmente importante para determinar se uma condição potencialmente tratável está presente e para identificar doenças com risco de recorrência em futuras gestações para aconselhamento pré-concepcional adequado.

In the remaining cases, the etiology was thoracic in 6.9% (eight cases), malformation syndromes in 4.3% (five cases), extrathoracic tumors in 3.4% (four cases), metabolic in 1.7% (two cases), and hematologic, gastrointestinal and genitourinary in 0.9% (one case each). During the postnatal period, 104 cases were followed up until the 40th day of life, and 12 cases had intrauterine fetal death. The survival rate of these 104 newborns was 23.1% (24 survived). CONCLUSION: An attempt should be made to clarify the etiology of hydrops diagnosed during pregnancy since the condition is associated with a wide spectrum of diseases. It is especially important to determine whether a potentially treatable condition is present and to identify disease at risk for recurrence in future pregnancies for adequate pre-conception counseling.

OBJECTIVE: Analyse the relation between insulin resistance and severe preeclampsia (SPE). METHODS: Case control study paired by body mass index and gestational age; including 16 patients with severe SPE and 16 normotensive controls. Insulin resistance was assessed through the HOMA-IR and QUICKI-IS indexes. RESULTS: There was no significant difference between the groups regarding the HOMA-IR and QUICKI-IS indexes and HDL cholesterol. Triglyceride levels were higher and the IGF-1 was lower in the SPE group than in the control group. CONCLUSIONS: There were no differences in the insulin resitance indexes between the group with SPE and normal controls.

PURPOSE: To verify the frequency of postsurgical pelvic adhesion formation in an experimental animal model using videolaparoscopy. METHODS: Experimental study in a sample of 11 non-pregnant female rabbits, aged 5 to 7 months. After general anesthesia, access to the abdominal cavity was performed by an open puncture technique, with 10mm optics, placing two other 5 mm trochars under direct visualization, in the iliac fossae. Then a fragment of peritoneum was resected, followed by electrocauterization. In 21 days, the videolaparoscopy was repeated, and adhesion formation and score was looked at, with biopsies at the surgical site. RESULTS: 54 % of adhesion formation was observed, and the median score of adhesions was 6 (minimum of 3 and maximum of 10), all of them found in the bladder and the anterior abdominal wall. CONCLUSION: The method used presents a high frequency of intra-abdominal adhesion formation.

PURPOSE: To describe the anesthetic protocol and the intubation technique without visualizing the trachea in rabbits, in order to enable the videolaparoscopic surgical procedure. METHODS: The experiment was performed on 33 female rabbits (Oryctolagus cuniculus), aged from 5 to 7 months. It consisted of general anesthesia and endotracheal intubation by manual palpation of the trachea of the rabbits, without using the laryngoscope, orally, for later videolaparoscopic surgical access to the abdominal cavity. RESULTS: The mean values and standard deviation of vital parameters of the animals were 223.8 + or - 15.61 beats per minute for heart rate; 35 + or - 9 movements per minute for respiratory rate; 96.94 + or - 0.99% of oxymetry and 42.82 + or - 4.02 mmHg for capnometry; 16.7 + or - 4.3 minutes for pneumoperitoneum (duration of surgery) and 1 hour and 14 + or - 8.52 minutes for time of observation (from induction to recovery from anesthesia). All animals were intubated in at most three attempts. No animals were lost after the introduction of this anesthetic technique. CONCLUSION: This protocol proved adequate, safe and easy to perform, on rabbits submitted to videolaparoscopic surgery.

OBJETIVO: Verificar a freqüência da formação de aderências pélvicas pós-cirúrgicas, em um modelo experimental animal, por videolaparoscopia. MÉTODOS: Estudo experimental, em uma amostra de 11 coelhas, não prenhas, com idade entre cinco e sete meses. Após anestesia geral, o acesso da cavidade abdominal foi efetuado por técnica de punção aberta, com óptica de 10 mm, colocando-se outros dois trocateres de 5 mm, sob visão direta, nas fossas ilíacas. Realizou-se, então, ressecção de fragmento de peritônio, seguida de cauterização com eletrocautério. Em 21 dias, foi repetida a videolaparoscopia, verificando-se a formação e escore de aderências e realizando-se biópsias do local da cirurgia. RESULTADOS: Observou-se 54,5 por cento de formação de aderências, sendo o escore total mediano de aderências seis (mínimo de três e máximo de 10), todas encontradas na bexiga e na parede abdominal anterior. CONCLUSÃO: O procedimento utilizado apresentou alta freqüência de formação de aderências intra-abdominais.

OBJECTIVE: To assess the urine protein/creatinine ratio in urine samples of pregnant women with hypertension in regard to: 1) the presence of significant variation at different periods of the day; 2) the differences if they exist, to identify the most reliable period of the day for sampling; and 3) whether the first sample, obtained when the patient arrives at the clinic, correlates with the same accuracy, with the 24-hour proteinuria. DESIGN: Cross-sectional study. PLACE: Obstetrics Emergency Department, Hospital de Clínicas de Porto Alegre, a teaching hospital in Porto Alegre, Brazil. POPULATION: Seventy-five women with hypertension with 20-week gestation or over. METHODS: Urine samples for determination of the protein/creatinine ratio were obtained on arrival (first specimen) and every 6 hours thereafter, totaling four samples in 24 hours. Four sampling periods were established: 1) from 8 am to 2 pm, 2) from 2 pm to 8 pm, 3) from 8 pm to 2 am, and 4) from 2 am to 8 am. The protein/creatinine ratio in the four different day periods were compared with the 24-hour proteinuria obtained simultaneously. The results were analyzed by the Spearman correlation and the receiver-operator characteristic (ROC) curve. RESULTS: The urine protein/creatinine ratio is strongly correlated (Spearman correlation equal to 0.8 or greater) with the 24-hour proteinuria at all four periods of the day (p<0.001), as well as the first sample obtained on arrival (p=0.003). These findings were corroborated by the ROC curve in which the values of four day periods and that of the first sample were equal to or greater than 0.930. CONCLUSION: In hypertensive pregnant women, the single voided urine sample protein/creatinine ratio, irrespective of sampling time, is strongly correlated with the 24-hour proteinuria, as is the sample obtained on arrival.

Foram inseridos 243 DIUS Multiload (MLCu-250) em 150 pacientes ao longo de 10 anos, sempre pelo mesmo profissional. Em 149 pacientes, o dispositivo foi usado como anticonceptivo. Em apenas um caso foi usado para tratamento da síndrome de Ashermann. Quarenta e três usuárias do DIU näo referiram qualquer queixa, correspondendo a 28,7 por cento das pacientes. Leucorréia, sangramento aumentado e cólica uterina foram as complicaçöes mais freqüentes. Ocorreu uma perfuraçäo uterina durante a inserçäo e um caso de doença inflamatória pélvica. Vinte e três pacientes tiveram o DIU retirado, por complicaçöes, correspondendo a 15,3 por cento do total de usuárias. A remoçäo por complicaçöes ocorreu igualmente entre nulíparas e multíparas. A expulsäo ocorreu em nove pacientes. Sete engravidaram com o DIU in situ e duas após expulsäo näo percebida, revelando baixo índice de falhas, levando-se em conta o número de DIUs e o período de tempo. O desejo de engravidar fez com que 21 mulheres tivessem o DIU removido. Destas, 15 tiveram seguimento na clínica, e a gestaçäo ocorreu em 13 no primeiro ano que se seguiu à remoçäo, correspondendo a 86,6 por cento das pacientes com acompanhamento que retiraram o DIU para gestar. O índice de adesividade pôde ser avaliado analisando-se o número de pacientes que usaram o DIU por mais de um ano (129 pacientes) e aquelas que retornaram ao uso após retirada por complicaçöes, incluindo gestaçäo e expulsäo (11 pacientes).
