Mental health aspects of emergency medical services for children: summary of a consensus conference.

OBJECTIVE: To address the mental health needs of children involved in emergency medical services (EMS). METHODS: A multidisciplinary consensus conference convened to identify mental health needs of children and their families related to pediatric medical emergencies, to examine the impact of psychological aspects of emergencies on recovery and satisfaction with care, and to delineate research questions related to mental health aspects of medical emergencies involving children. RESULTS: The consensus group found that psychological and behavioral factors affect physical as well as emotional recovery after medical emergencies. Children's reactions are critically affected by age and developmental level, characteristics of the emergency medical event, and parent reactions. As frontline health care providers, EMS staff members are in a pivotal position to recognize and effectively manage the mental health needs of patients and their families. CONCLUSIONS: Ecological changes in emergency departments, such as linkages to mental health follow-up services, training of EMS providers and mental health professionals, and focused research that provides an empirical basis for practice, are necessary components for improving current standards of health care.

A multi-institutional study of factors associated with fetal death in injured pregnant patients.

HYPOTHESIS: Factors associated with fetal death in injured pregnant patients are related to increasing injury severity and abnormal maternal physiologic profile. DESIGN: A multi-institutional retrospective study of 13 level I and level II trauma centers from 1992 to 1996. MAIN OUTCOME MEASURE: Fetal survival. RESULTS: Of 27,715 female admissions, there were 372 injured pregnant patients (1.3%); 84% had blunt injuries and 16% had penetrating injuries. There were 14 maternal deaths (3.8%) and 35 fetal deaths (9.4%). The population suffering fetal death had higher injury severity scores (P<.001), lower Glascow Coma Scale scores (P<.001), and lower admitting maternal pH (P = .002). Most women who lost their fetus arrived in shock (P = .005) or had a fetal heart rate of less than 110 beats/min at some time during their hospitalization (P<.001). An Injury Severity Score greater than 25 was associated with a 50% incidence of fetal death. Placental abruption was the most frequent complication, occurring in 3.5% of patients and associated with 54% mortality. Cardiotrophic monitoring to detect potentially threatening fetal heart rates was performed on only 61% of pregnant women in their third trimester. Of these patients, 7 had abnormalities on cardiotrophic monitoring and underwent successful cesarean delivery. CONCLUSIONS: Fetal death was more likely with greater severity of injury. Cardiotrophic monitoring is underused in injured pregnant patients in their third trimester even after admission to major trauma centers. Increased use of cardiotrophic monitoring may decrease the mortality caused by placental abruption.

Response of crescentic Henoch-Schoenlein purpura nephritis to corticosteroid and azathioprine therapy.

The benefits of treating severe Henoch-Schoenlein Purpura (HSP) glomerulonephritis have not been established. In this study, we evaluate the outcome of 21 children with severe HSP nephritis treated with corticosteroids and azathioprine. Between 1977 and 1995, 78 children (age range 1 to 16 years) were seen for evaluation of HSP. Thirty-one underwent kidney biopsy; indications included nephritic and/or nephrotic onset (15 patients), persistently decreased creatinine clearance (5 patients), or proteinuria > 4 g/24 h (11 patients). Twenty treated patients had diffuse mesangial proliferation with crescents in 6-100% (mean 40%) of glomeruli. One treated patient, not biopsied due to extreme obesity, had a creatinine clearance of 49 ml/min/1.73 m2 and proteinuria of 21.3 g/24 h. These 21 patients were initially treated with azathioprine and daily oral prednisone (13 patients) or i.v. methyl-prednisolone (8 patients), followed by azathioprine and alternate-day prednisone for 9-24 (mean 15) months. The average follow-up was 32 months. Over the course of follow-up, 19 treated patients showed a decline in hematuria (> 5 red blood cells/high power field) from 100% to 16% (p < 0.01), a fall in the serum creatinine from 1.71 +/- 2.20 to 0.78 +/- 0.25 mg/dl (p < 0.01), an increase in creatinine clearance from 76 +/- 43 to 122 +/- 26 ml/min/1.73 m2 (p < 0.01), and a reduction in proteinuria from 8.8 +/- 7.5 to 0.47 +/- 0.39 g/24 h (p < 0.01). Two treated patients progressed to end-stage renal failure. There was no difference in outcome comparing patients initially treated with prednisone versus methyl-prednisolone. These observations suggest that corticosteroid and azathioprine therapy is effective in crescentic HSP nephritis.

Goodpasture's syndrome in childhood: treatment with plasmapheresis and immunosuppression.

Goodpasture's syndrome rarely affects children. Therefore, we present our experience in a young boy whose pulmonary hemorrhage was dramatically resolved by three plasma exchanges. We believe the hemorrhage was caused primarily by acute capillaritis. He received cytoxan and steroids and a series of plasma exchanges which removed/suppressed his anti-glomerular basement membrane (anti-GBM) antibody production. However, after a year, his renal function did not return, and he required renal transplantation and continues to do well.

Peritoneal dialysis in the first 60 days of life.

This report describes a 7-year experience with acute peritoneal dialysis in 31 neonates and infants less than 60 days of age. There were 20 boys and 11 girls, ages 3 to 60 days. Tenckhoff catheters of modified length were placed in the newborn intensive care unit (ICU), pediatric ICU, or surgery suites, and hourly exchanges (20 cc/kg) were started immediately postoperatively. Diagnoses included congenital metabolic disorders (11), acute tubular necrosis (6), postcardiopulmonary bypass with renal failure (5), renal cortical necrosis (5), obstructive uropathy (2), renal agenesis (1), and bilateral renal dysplasia (1). Complications included: peritonitis (4), bowel perforation (1), exit site infection (3), leaking dialysate (4), catheter obstruction (2), inguinal hernias (3), umbilical hernia (1), and retroperitoneal hemorrhage (1). There were 19 deaths (61.3%) from 1 to 90 days postinsertion in this high risk group. The (1), and post liver transplant (1). Effective dialysis (lowering of blood urea nitrogen (BUN) or ammonia, correction of acidosis, decrease in fluid overload) was possible in all cases. Five of the 12 survivors remain on chronic dialysis awaiting renal transplantation. Peritoneal dialysis is effective in the newborn period in the management of metabolic disturbances as well as renal failure. Morbidity and mortality (61.3%) is related to the near-morbid condition of the baby at the time of insertion and the severity of the complex underlying diagnosis often associated with multiorgan failure.

Radiation nephritis following total-body irradiation and cyclophosphamide in preparation for bone marrow transplantation.

Two children prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide developed hypertension, microscopic hematuria, proteinuria, diminished renal function, and anemia six months after transplantation. Light microscopy of the kidneys revealed mesangial expansion, glomerular capillary wall thickening, and lumenal thrombosis. Electron microscopy demonstrated widening of the subendothelial space due to the deposition of amorphous fluffy material. In one patient, immunofluorescence microscopy revealed glomerular capillary wall deposition of fibrin and immunoglobulins. The clinical and histologic findings support the diagnosis of radiation nephritis. Patients prepared for bone marrow transplantation with total-body irradiation and cyclophosphamide should be followed closely after transplantation for the development of hypertension, proteinuria, and renal insufficiency.

Massive gastric hemorrhage: an unusual complication of Henoch-Schönlein purpura.

Two severely ill children with multisystem involvement of Henoch-Schönlein purpura developed massive upper gastrointestinal hemorrhage, requiring operative ligation of gastric stress ulcers, and vagotomy and pyloroplasty. Arteriographic embolization was also used in one of the children when she developed recurrent hemorrhage. Survival in both children emphasizes the need for aggressive management of the many complications these children may develop.

Genetic and pathophysiologic studies of a new kindred with glucocorticoid-suppressible hyperaldosteronism manifest in three generations.

This report describes investigations in a new kindred with dexamethasone-suppressible hyperaldosteronism affecting three successive generations. The presumptive diagnosis was first made in a 7-yr-old boy and led to the identification of the disorder in his mother and grandmother. Several other members of the family were investigated. Genotyping and HLA typing were also performed. To further explore the nature of this unusual disorder, urine from the three patients documented to have the syndrome was assayed for an aldosterone-stimulating factor recently reported to be found in patients with idiopathic aldosteronism. None of these patients showed measurable activity of such a urinary factor. The identification of members in three generations strongly supports the heritable nature of the disorder and probable autosomal dominant type of transmission. The absence of urinary aldosterone-stimulating factor in these patients further supports the tenet that the disorder is pathogenetically distinct from idiopathic aldosteronism, since both disorders are usually associated with bilateral adrenal hyperplasia.

Chronic interstitial nephritis. Its occurrence with oxalosis and anti-tubular basement membrane antibodies after jejunoileal bypass.

A 38-year-old woman suffered rapid onset of renal failure between 11 and 15 months after undergoing a jejunoileal bypass for morbid obesity. Microscopic examination of renal biopsy specimens revealed oxalosis and severe tubulointerstitial nephritis. Immunofluorescence microscopy disclosed linear staining of tubular basement membranes with antisera to IgG and C3, which suggests antitubular basement membrane disease, a side effect not previously recognized with jejunoileal bypass. Possible mechanisms leading to the formation of these antibodies include (1) oxalate damage to renal tubules with release of tubular basement membrane antigens, and (2) bacterial overgrowth in the bypass segment, with mucosal damage and release of intestinal mucosal antigens that share antigenetic determinants with renal proximal tubules. Anti-tubular basement membrane disease may be an additional mechanism that produces or enhances renal damage in patients with jejunoileal bypass.

Childhood primary aldosteronism due to an adrenal adenoma: preoperative localization by adrenal vein catheterization.

Primary aldosteronism resulting from an adrenal adenoma is rare in children. An 8 1/2-year-old girl was found to have hypertension and spontaneous hypokalemia, both detected as incidental findings. Subsequent investigations revealed inappropriately elevated levels of plasma and urinary aldosterone with suppressed plasma renin activity. Adrenal vein blood sampling and venography suggested the presence of left adrenal adenoma which was confirmed at surgical exploration and pathologic examination. All the clinical and biochemical abnormalities were corrected by the adrenalectomy. The differential diagnoses of various types of hyperaldosteronism and/or hypokalemia in such a clinical setting are discussed.

Postpubertal evaluation of gonadal function following cyclophosphamide therapy before and during puberty.

Evaluation of pituitary gonadotropins, gonadal steroids, spermatogenesis, and menstrual function was undertaken in 32 patients (19 males and 13 females) treated with cyclophosphamide because of nephrotic syndrome. Patients were treated before, during, or after puberty. Evaluations took place after or in very late puberty. Spermatogenic dysfunction occurred in six of 15 boys who received the entire course before and during puberty and was probably dose related. Menstrual dysfunction did not occur following treatment of six prepubertal or pubertal girls, though only low total doses were used. Therapy after puberty was associated with spermatogenic dysfunction in all four boys, but did not cause menstrual dysfunction in any of seven women. Tentative guidelines are suggested that many minimize gonadal toxicity when cyclophosphamide is used in children with nephrotic syndrome. Factors of particular importance in the interpretation of gonadotropin determinations and of sperm counts in young cyclophosphamide-treated patients are discussed.

Enterocolitis with peritonitis in a child with pheochromocytoma.

An 8-year-old boy presented at UCLA Hospital with a one month history of hypertension prior to suffering a sudden onset of acute abdominal pain, rectal bleeding, peritonitis, and shock. Sigmoidoscopy showed diffuse mucosal friability. At laparotomy, inflammation and edema of the entire colon and terminal ileum were detected with two necrotic areas on the cecum. A 5 cm right adrenal pheochromocytoma with a hemorrhagic center was removed and a diverting loop ileostomy with inversion of the necrotic cecal areas was performed. Postoperatively, the blood pressure gradually returned to normal, and the colitis improved. Serum calcium and T3 T4 levels were normal. Review of the literature demonstrates that in patients with pheochromocytoma, progression from colitis to necrosis can be precipitated by a hypotensive episode. This patient suggests an example of catecholamine induced enterocolitis.

Interstitial nephritis with anti-tubular-basement-membrane antibody.

To determine the pathogenesis of interstitial nephtitis, immunopathological studies were performed with kidney and serum from a six-year-old boy. The kidney revealed linear staining of tubular basement membranes with antiserums specific for human IgG and C3; the membranes also showed fixation of heterologous complement. After incubation of the patient's serum on frozen sections from normal human kidneys, linear staining with IgG was detected by indirect fluorescence. This staining was eliminated by absorption of the serum with purified tubular basement membranes, but was unaltered by absorption with purified glomerular basement membrane. The antibody reacted with mouse, rabbit, dog, sheep, monkey, Sprague-Dawley and Lewis/Brown Norway rat tubular basement membranes, but not with that of Lewis rat or guinea pig, or with human skin, thyroid, parotid, lung, liver or pancreas. Anit-tubular-basement-membrane antibody may be involved in the pathogenesis of the patient's disease.
