Relationship between the Prenatal Diagnosis of Placenta Acreta Spectrum and Lower Use of Blood Components / Relação entre o diagnóstico prenatal de espectro da placenta acreta e menor uso de hemoderivados

Abstract Objective To describe the clinical results of patients admitted and managed as cases of placenta accreta spectrum (PAS) at a Central American public hospital and the influence of the prenatal diagnosis on the condition. Materials and Methods A retrospective analysis of PAS patients treated at Hospital Bertha Calderón Roque, in Managua, Nicaragua, between June 2017 and September 2021. The diagnostic criteria used were those of the International Federation of Gynecology and Obstetrics (Fédération Internationale de Gynécologie et d'Obstétrique, FIGO, in French). The population was divided into patients with a prenatal ultrasonographic diagnosis of PAS (group 1) and those whose the diagnosis of PAS was established at the time of the caesarean section (group 2). Results During the search, we found 103 cases with a histological and/or clinical diagnosis of PAS; groups 1 and 2 were composed of 51 and 52 patients respectively. Regarding the clinical results of both groups, the patients in group 1 presented a lower frequency of transfusions (56.9% versus 96.1% in group 2), use of a lower number of red blood cell units (RBCUs) among those undergoing transfusions (median: 1; interquartile range: [IQR]: 0-4 versus median: 3; [IQR]: 2-4] in group 2), and lower frequency of 4 or more RBCU transfusions (29.4% versus 46.1% in group 2). Group 1 also exhibited a non-significant trend toward a lower volume of blood loss (1,000 mL [IQR]: 750-2,000 mL versus 1,500 mL [IQR]: 1,200-1,800 mL in group 2), and lower requirement of pelvic packing (1.9% versus 7.7% in group 2). Conclusion Establishing a prenatal diagnosis of PAS is related to a lower frequency of transfusions. We observed a high frequency of prenatal diagnostic failures of PAS. It is a priority to improve prenatal detection of this disease.

Ultrasound Diagnosis in Small Ruminants: Occurrence and Description of Genital Pathologies.

This study reports the occurrence and appearance of various reproductive tract pathologies of small ruminants diagnosed using ultrasound. An eight-year retrospective study of collected ultrasound data was carried out in Rio de Janeiro State, Brazil from September 2012 to July 2020. A total of 3463 animals from 16 sheep flocks and 10 dairy goat flocks, raised under extensive and intensive management systems, respectively, were used in the study. All animals were submitted to an ultrasound examination of their reproductive tract. Data were analyzed using Fisher's exact test (p < 0.05), to compare disorder frequencies within and between species. Ewes (4.14%) had fewer reproductive disorders than does (8.98%), while rams (43.63%) and bucks (56.25%) presented no significant differences. Hydrometra was the most frequent finding in does, represented by 50.98% of cases; while, in ewes, recent fetal loss (22.85%) and cystic endometrial hyperplasia (20.00%) were the most frequent. In bucks, the findings showed no clear differences; while, for rams, the most frequent finding was testicular microlithiasis (75.00%). Ultrasonography offers clinically useful information about the reproductive tract via the images it provides; knowledge of which makes it possible to improve the diagnosis, therapy, and prognosis of genital pathologies.

Diagnostic histopathological-ultrasonographic correlation in patients categorized as BI-RADS 4.

OBJECTIVE: To correlate ultrasonographic and histopathological diagnosis in patients categorized as breast imaging reporting and data system (BI-RADS) 4. METHOD: Cross-sectional study, performed on patients with BI-RADS 4 (A, B or C) diagnosed by ultrasonography in the high specialty medical unit, hospital of specialties, Centro Médico Nacional General de División Manuel Ávila Camacho, of the Instituto Mexicano del Seguro Social. Age, ultrasonographic and histopathological diagnosis, menarquia, menopause, gestations, lactation, use of contraceptives and family history of breast cancer were evaluated. RESULTS: 101 patients categorized BI-RADS 4 were included; average age was 53.0 ± 8.3 years old, 6.9% of the patients were nulliparous, 92.2% with positive breastfeeding and 25.7% had a family history of breast cancer. By ultrasonography, 55.4% of the cases were BI-RADS 4A, 22.8% 4B and 21.8% 4C. 75.2% of the biopsies performed on the patients were benign and 24.8% were malignant. The overall ultrasonographic-histopathological concordance index was 0.25; 0.11 for BI-RADS 4A, 0.22 for BI-RADS 4B and 0.63 for BI-RADS 4C. CONCLUSION: The ultrasound-histopathological correlation is weak and inferior to that reported in the literature.

OBJETIVO: Correlacionar el diagnóstico ultrasonográfico con el histopatológico en pacientes categorizadas como BI-RADS 4. MÉTODO: Estudio transversal en pacientes con BI-RADS 4 (A, B o C) diagnosticado por ultrasonografía en la Unidad Médica de Alta Especialidad Hospital de Especialidades Centro Médico Nacional General de División Manuel Ávila Camacho, del Instituto Mexicano del Seguro Social. Se evaluaron la edad, el diagnóstico ultrasonográfico, el resultado histopatológico, la edad de primera y última menstruación, el número de gestas, la lactancia, el uso de anticonceptivos y los antecedentes familiares de cáncer de mama. RESULTADOS: Se incluyeron 101 pacientes con BI-RADS 4, con una edad promedio de 53.0 ± 8.3 años. El 6.9% de las pacientes eran nulíparas. El 92.2% habían realizado lactancia. El 25.7% tenían antecedentes familiares de cáncer de mama. Por ultrasonografía, el 55.4% de los casos eran BI-RADS 4A, el 22.8% eran 4B y el 21.8% eran 4C. El 75.2% de las biopsias realizadas a las pacientes fueron benignas y el 24.8% fueron malignas. El índice de concordancia global ultrasonográfica-histopatológica fue de 0.25; para BI-RADS 4A fue de 0.11, para BI-RADS 4B fue de 0.22 y para BI-RADS 4C fue de 0.63. CONCLUSIÓN: La correlación ultrasonográfica-histopatológica es débil e inferior a la reportada en la literatura.

Avaliação ultra-sonográfica da apendicite aguda / Ultrasonographic evaluation of acute appendicitis

OBJETIVO: A apendicite aguda é a mais comum urgência cirúrgica abdominal. Na tentativa de aumentar a acurácia diagnóstica a ultra-sonografia abdominal tem sido observada como método sensível e específico. O presente estudo tem por objetivo avaliar a ultra-sonografia do abdome no diagnóstico de apendicite aguda. MÉTODO: Um total de 138 pacientes submetidos a tratamento cirúrgico com suspeita diagnóstica admitidos no Hospital Municipal Djalma Marques foi estudado no período de janeiro de 1997 a dezembro de 1998. Todos os exames foram realizados na mesma instituição e havia 87 pacientes do sexo masculino (63,0 por cento) e 51 do sexo feminino (37,0 por cento) com idade variando de 11 a 81 anos (média de 28,4 anos). RESULTADOS: Dos 134 casos com diagnóstico comprovado cirurgicamente, o estudo ultra-sonográfico foi positivo em 114 (sensibilidade de 85,0 por cento). O apêndice foi visualizado como imagem longitudinal ou transversal maior do que 7mm em 75 dos 114 achados positivos (65,8 por cento). CONCLUSÕES: Os autores concluem que a ultra-sonografia abdominal é um instrumento valioso no diagnóstico de apendicite aguda.

BACKGROUND: Acute appendicitis is the most common disease leading to emergency abdominal surgery. Many diagnostic tools have been evaluated. Abdominal ultrasonography is sensitive and specific which increase diagnostic accuracy in acute appendicitis. The aim of the present study is to evaluate the abdominal ultrasonography in the diagnosis of acute appendicitis. METHOD: A total of 138 patients underwent surgical treatment for suspected appendicitis admitted to the Hospital Municipal Djalma Marques from January 1997 to December 1998. All abdominal ultrasonography examinations were performed at same hospital. There were 87 male (63.0 percent) and 51 female (37.0 percent), and their ages ranged from 11 to 81 years (mean 28.4 years). RESULTS: Of the 134 patients with proved appendicitis at surgery the ultrasonographic diagnosis was positive in 114 (sensitivity of 85.0 percent). The appendix was visualized on a longitudinal or transverse image > 7mm in 75 patients of the 114 positive findings (65.8 percent). CONCLUSIONS: It can be concluded that abdominal ultrasonography examination is a valuable tool in diagnosis of acute appendicitis.
