ABSTRACT

Allergic colitis can occur within hours of birth and should be considered in the differential diagnosis of any newborn in whom hematochezia develops. This diagnosis should be considered after excluding infectious and anatomic disorders common to this age group. The diagnosis is supported by the healthy appearance of affected infants and specific proctosigmoidoscopic and histopathologic findings. Infants with allergic colitis usually respond to withdrawal of the offending antigen, by the use of hydrolyzed cow's milk protein formula or more elemental formulas, or if the infant has been breast fed, by the strict removal of the offending antigen from the breast-feeding mother's diet.

ABSTRACT

Type I spinal muscular atrophy (SMA) is a rapidly progressive, degenerative neuromuscular disease of infancy. In severe SMA, weakness, hypotonia, and bulbar involvement lead to progressive respiratory insufficiency and swallowing dysfunction, which are frequently complicated by aspirations. There are few studies reported in the literature that address the respiratory management of type I SMA. This article reports the results of treating four patients with infantile SMA with noninvasive positive pressure ventilation and gastrostomy feeding. All patients had gastroesophageal reflux disease, which was managed medically. Despite these therapies, survival was only 1 to 3.5 months after presenting with severe aspirations. The treatment strategy, which can be effective in less rapidly progressive neuromuscular diseases, did not alter the very poor prognosis of type I SMA. The treatment options are reviewed, and a strategy designed to optimize quality of life for infants with this fatal disease is presented.

ABSTRACT

Noninvasive positive pressure ventilation (NPPV) is used for respiratory support in a number of diseases causing acute or chronic respiratory failure. We describe a novel use of NPPV to provide respiratory support during sedation for percutaneous placement of a gastrostomy tube in a patient with Duchenne muscular dystrophy (DMD). The patient had severe respiratory insufficiency, progressive dysphagia, and undernutrition. In addition to the case in this report, we have used NPPV to provide respiratory support to DMD patients during five other gastrointestinal endoscopies without complication. The technique is highly labor intensive and requires physicians and respiratory therapists familiar with NPPV. The primary risk associated with this technique is lack of definitive airway protection during the procedure, which must be balanced against the risks of intubation in an anesthetized patient with neuromuscular disease. The potential benefit to selected patients is substantial, such as initiation of gastrostomy tube feeding in our patient, with subsequent improvement in his quality of life and nutritional status.

ABSTRACT

BACKGROUND: Irradiation of platelet concentrates (PCs) with ultraviolet-B (UVB) light inactivates the contaminating white cells and might be an alternative to filtration for the prevention of alloimmunization to HLA antigens and subsequent refractoriness to further platelet transfusions in multiply transfused patients with bone marrow failure. STUDY DESIGN AND METHODS: Patients with hematologic malignancy, mainly acute myeloid leukemia, were prospectively assigned in a random manner to receive either UVB-irradiated or control, nonirradiated PCs. All patients were given red cells that were white cell reduced by filtration. Transfusion efficacy and alloimmunization were assessed by means of corrected count increments, requirement for red cells and PCs, and measurement of lymphocyte-reactive antibodies. RESULTS: UVB-irradiated PCs had a clinical efficacy similar to controls as judged by corrected count increments at 1 to 6 and 12 to 24 hours and by the median requirement for red cell and platelet transfusions. Alloimmunization determined by measurements of lymphocyte-reactive antibodies using both conventional and antiglobulin-augmented lymphocytotoxicity techniques was not abolished in recipients of UVB-irradiated PCs (4/30, 13%) but was less than that in controls (5/20, 25%; p = NS). The mean number of platelet transfusion episodes prior to the occurrence of alloimmunization was greater in the control group (27 vs. 10; p = 0.017). CONCLUSION: In this trial, UVB irradiation did not diminish the clinical efficacy of platelet transfusions. There was a small but nonsignificant reduction alloimmunization, but no difference in refractoriness of the two groups was observed. Larger prospective randomized studies are required to confirm these findings and to compare UVB irradiation with white cell reduction.
