A neonate with increased nuchal translucency and congenital adrenal hyperplasia is described. The possible interferences in hormone assays when values are much higher than the average assay range are also discussed.
A study was performed to determine, in our population, the relationship between transcutaneous, visual and serum bilirubin values. This was done in attempts to reduce the number of serum bilirubin determinations to be performed in the future. We did a correlation coefficient between serum bilirubin and five measurements of transcutaneous bilirubin levels in a group of 60 term newborns and 60 preterm newborns, obtaining a value of 0.84 in both groups. The results were also considered from an analytical point of view where the ability of the test to predict an alteration in serum bilirubin levels, for example > or = 12 mg/dl in preterm and > or = 13 mg/dl in term newborns, was assessed. For values of 18 in preterm and 17 in term infants, the transcutaneous method was found to be both sensitive and specific. If Kramer's test is also evaluated the results improve.
We have reviewed 108 emergency ward reports of patients with adenoviral positive cultures in "Doce de Octubre" Hospital in Madrid. Our aim was to know the most frequent symptoms of the infection so that identification and treatment could be managed more efficiently in our department. Cellular cultures were negative for other viruses such as CMV, enterovirus and herpesvirus. No bacteria were found in the throat cultures. Of the children who were evaluated, 78% were younger than 3 years old. The most frequent symptom was high fever with an otherwise good state of health. During the physical examination, a reddened throat with an exudate was found in half of the patients. A white blood cell count of over 15,000 was found in 33% of the patients with a left shift in 20%. The clinical findings overlapped with throat bacterial infections in 66%, lower respiratory infections in 14%, and more unusual, gastroenteritis, hematuria, intestinal invagination or exanthemas. Only 15% were not given antibiotic therapy.
We report a retrospective study of 51 children who presented urolithiasis between 1980 and 1989 in our Hospital. Mean age was 7 years and the male:female ratio was 2. 1:1. A positive family history was found in 60% of cases. It was done metabolic evaluation in every case: hypercalciuria was found in 34% of cases. In 6% of cases there were hyperuricosuria. None of our patients presented hyperoxaluria, cystinuria or hypocitraturia. Abdominal echography was the most sensible an specific imaging technique of diagnosis. In 16 cases it was necessary a surgical procedure although most cases received only medical management. Four patients were treated with extracorporeal shock-wave lithotripsy. We emphasize the importance of metabolic evaluation. We report our own protocol of study and results.
We analyzed 8 cases of meningococcal septic shock diagnosed in a three year period. The age varied from 20 months to 10 years (mean: 4.8 years). Two patients died. Every child was monitored with a Swan-Ganz catheter 5 F or 7F, placed on by puncture of internal jugular or subclavicular veins. Of this hemodynamic study, we can conclude that in septic shock, there is a myocardial depression, that persist for several days, and improves with dopamine and dobutamine. In addition to this, in sepsis exists a pulmonary hypertension that makes worse the prognosis.
We analyze 13 children between 1 and 3 years old (mean: 24.6 +/- 6.5 months), who were diagnosed (by direct or radiological examination) of epiglottitis. Seven were male. All of them had fever and respiratory distress. Six blood cultures (46%) were positive for Hemophilus Influenzae, and in 5 cases were resistant to beta-lactamases. Diagnose was made by radiology (70%) or by direct examination (30%). Five patients were not intubated (38%), with a favorable outcome. One died after a cardiorespiratory arrest due to self-extubation. We describe in this study our experience in the conservative treatment of epiglotitis, although initial nasotracheal intubation is the safest method for the management of this entity.
We study the renal function in meningococcal sepsis in other to get prognostic data in disease evolution. We include 116 patients of whom we take data of anamnesis; physical examination; blood, urine and cerebrospinal fluid biochemical and microbiologic studies and TISS and APS score. We analyze qualitative and quantitative data of renal function statistical and we compare with another prognostic data of disease. We find that renal failure in meningococcal sepsis gets worse the prognostic of the disease.
We analysed 7 cases of systemic candida sp. infection diagnosed between 1986 to 1989. Clinical presentation was of sepsis. Evolution was favorable in all, excepting two cases that died due to a candidiasic meningitis and a candidiasic aortic thrombosis, respectively. Almost all patients were treated with amphotericin B only. A newborn had signs of toxicity (thrombocytopenia). We emphasize the importance of a prompt diagnosis and treatment and the effectivity of amphotericin B for systemic candidiasis, besides of its rare toxicity in newborns.
