1/12. Disseminated intravascular meconium in a newborn with meconium peritonitis.A 3-day-old premature infant with meconium peritonitis, periventricular leukomalacia, and pulmonary hypertension died with respiratory insufficiency. An autopsy disclosed intravascular squamous cells in the lungs, brain, liver, pancreas, and kidneys. Numerous pulmonary capillaries and arterioles were occluded by squamous cells, accounting for pulmonary hypertension. brain parenchyma surrounding occluded cerebral vessels showed infarct and gliosis. A mediastinal lymph node filled with squamous cells alluded to the mechanism by which these cells from the peritoneal cavity likely entered the bloodstream--namely, via diaphragmatic pores connecting with lymphatics. Thus, disseminated intravascular meconium rarely may complicate meconium peritonitis and have devastating consequences.- - - - - - - - - - ranking = 1keywords = meconium (Clic here for more details about this article) |
2/12. An unusual case of neonatal peritoneal calcifications associated with hydrometrocolpos.Neonatal peritoneal calcifications usually suggest a diagnosis of meconium peritonitis, but in this case, a premature baby girl, peritoneal calcifications were caused by hydrometrocolpos secondary to imperforate hymen, a rare association. The patient presented with respiratory distress and ascites and demonstrated abdominal calcifications on plain film. Other radiographic work-up revealed hydrometrocolpos without evidence of gastrointestinal tract obstruction. The patient was diagnosed and treated for imperforate hymen; she was recovered fully.- - - - - - - - - - ranking = 0.090909090909091keywords = meconium (Clic here for more details about this article) |
3/12. meconium obstruction in the very low birth weight premature infant.meconium obstruction of prematurity is a distinct clinical condition that occurs in very low birth weight infants, predisposing them to intestinal perforation and a prolonged hospitalization if not diagnosed and treated promptly. We report a series of 21 infants, including 2 detailed case reports, whose clinical course is indicative of meconium obstruction of prematurity. Specific risk factors are identified along with descriptions of clinical and radiologic findings, disease course, treatment, and outcome. meconium obstruction of prematurity was more common in infants with a maternal history of pregnancy-induced or chronic hypertension, suggesting the possibility of decreased intestinal perfusion prenatally. Inspissated meconium was located most frequently in the distal ileum, making this disease process difficult to treat. Gastrografin enemas were safe, diagnostic, and therapeutic. Delay in diagnosis and treatment was associated with perforation and delay in institution of enteral feeds.- - - - - - - - - - ranking = 0.18181818181818keywords = meconium (Clic here for more details about this article) |
4/12. meconium peritonitis and parvovirus B19 infection associated with hydrops fetalis.Two preterm infants with non-immune hydrops fetalis associated with meconium peritonitis are reported. The first presented with a cystic abdominal mass and the second had positive parvovirus B19 serology. The association of meconium peritonitis with hydrops fetalis was through different mechanisms in each patient.- - - - - - - - - - ranking = 0.18181818181818keywords = meconium (Clic here for more details about this article) |
5/12. meconium peritonitis: a benign course in a premature infant.A case of a premature infant with meconium peritonitis and intraperitoneal calcifications is described. The course of illness was mild and recovery complete. No evidence of congenital intestinal obstruction or cystic fibrosis was found.- - - - - - - - - - ranking = 0.090909090909091keywords = meconium (Clic here for more details about this article) |
6/12. Enterolithiasis with imperforate anus. Report of two cases with sonographic demonstration and occurrence in a female.Enterolithiasis has been previously described as a plain film finding of rectovesical or rectourethral fistula in patients with anorectal malformation. Two cases of enterolithiasis with anorectal malformation are described in which the intraluminal nature of the calcifications was identified using ultrasound. The use of ultrasound for this purpose has not been previously reported to our knowledge. This simple, noninvasive technique permits antenatal differentiation between enterolithiasis and meconium peritonitis in some patients and can suggest the prenatal diagnosis of rectourinary communication when enterolithiasis is present. In addition, one of our cases occurred in a female. The entity of enterolithiasis with imperforate anus in a female has not been previously reported.- - - - - - - - - - ranking = 0.090909090909091keywords = meconium (Clic here for more details about this article) |
7/12. A case of meconium peritonitis: the pathological findings.An autopsy case of meconium peritonitis is described. This baby was born at 24 weeks of gestation. The pathological findings were generalized peritonitis and this inflammation spread to the umbilical cord. It can be thought that the cause of premature labor may be in part some inflammatory process.- - - - - - - - - - ranking = 0.45454545454545keywords = meconium (Clic here for more details about this article) |
8/12. meconium plugs and intussusception in a premature infant.Neonatal intussusception in premature infants is uncommon and may mimic other abdominal disorders. We present a case of intussusception in a very low birthweight neonate. Presenting signs initially suggested necrotizing enterocolitis and meconium disease, and the diagnosis was confirmed at laparotomy.- - - - - - - - - - ranking = 0.090909090909091keywords = meconium (Clic here for more details about this article) |
9/12. Neonatal meconium blockage in the ileum and proximal colon.Three cases of premature infants with obstruction of the ileum and proximal colon in the absence of cystic fibrosis are presented. meconium inspissation complicated low-grade bowel obstruction in 2 infants. In the third, the bowel was anatomically normal, with the tenacious meconium the apparent primary cause of obstruction. Distinguishing features of this unusual type of blockage and other meconium syndromes are also discussed. This condition may simulate necrotizing enterocolitis, requiring surgery for differentiation. It should be considered in the differential diagnosis of low small bowel or colonic obstruction in the premature infant who is several days of age.- - - - - - - - - - ranking = 0.54545454545455keywords = meconium (Clic here for more details about this article) |
10/12. Intraluminal meconium calcification without distal obstruction.Intraluminal meconium calcification of unknown mechanism is reported in three neonates who did not have distal intestinal obstruction. The condition was benign in all three cases and did not require surgical intervention. This new form of intra-abdominal calcification should be differentiated from other forms that invariably are due to surgical disorders.- - - - - - - - - - ranking = 0.45454545454545keywords = meconium (Clic here for more details about this article) |
