BackgroundFecaloma is a mass of feces accumulated that is much harder in consistency than a fecal impactation. The aim of this report is to give a brief review of this entity and discuss the treatment options for these cases.Case presentationWe present the case of a 12-year-old boy who developed a fecaloma associated with chronic constipation. This is a rare case on a child which was treated by a sigmoid colectomy after failure of conservative measures of evacuation.ConclusionFecaloma should be considered in the differential diagnosis of patients with history of chronic constipation and abdominal mass.
SummaryAnesthetized young rabbits were ventilated for 6 hr at 20 cm HzO peak airway pressure using air nebulized with water at 22OC (cold nebulized group, n = 11). at 36OC (warm nebulized group, n = 11) and humidified air at 36OC (warm humidified group. n = 10).Their biochemical status during ventilation and pulmonary morphology at autopsy were compared to those of ten control rabbits. Both nebulized groups had particulate water in the inspired air and water of condensation in the endotracheal tube.The rabbits ventilated with warm humidified air and the control group breathing spontaneously maintained their blood pressure and pHa within physiologic range. Rabbits ventilated with air nebulized with water at 22 and 36°C had a significant decline in mean blood pressure (% mm Hg -61 mm Hg in cold nebulized and 91 mm Hg -. 61 mm Hg in warm nebulized) and mean pHa (7.43 -. 7.23 in cold nebulized and 7.42 -+ 7.31 in warm nebulized).All rabbits in the control and warm humidified groups survived the study whereas 9 of 22 in the nebulized groups died before completion of study ( P < 0.005).Morphometric analysis revealed a significant increase in the mean vascular wall thickness in both nebulized groups of rabbits when compared to that in the control and warm humidified groups ( P < 0.05). The cold nebulized group also had significantly less air space and correspondingly more interstitial thickness and intraalveolar edema ( P < 0.05) compared to control and warm humidified groups. ~h e s e findings of bulmonary parenchymal damage in rabbits ventilated with air containine oarticulate water and the -.greater degree of both physiologic and anatomic change evident in the cold nebulized animals suggest that particulate water and low inspired air temperature may contribute to the genesis of pulmonary damage during intermittent positive pressure ventilation. SpeculationThe phenomenon of reflex pulmonary hypertension following instillation of small quantities of fresh water to the lung (5) might occur even if miniscule amounts of particulate water are delivered during intermittent positive pressure ventilation. Particulate water in inspired air could therefore play a role in the pulmonary parenchymal damage seen in babies treated with intermittent positive pressure ventilation. Failure to maintain temperature of the inspired air at body temperature during intermittent positive pressure ventilation (25) may also have a deleterious effect in the human infant.The observations made by Northway et al. (29) in humans and deLemos el al. (7) in lambs suggest that use of high concentrations of oxygen during intermittent positive pressure ventilation (IPPV) is responsible for parenchymal changes seen in lungs of humans subjected to IPPV. More recent studies suggest that barotrauma may be a contributing factor (36. 37). In a previous study. we demonstrated lesions similar to those described by deLemos et al.
