We report a case of bone pain associated with primary hyperparathyroidism in a patient with sickle cell disease. A 17-year-old girl with sickle cell disease (SS phenotype) was seen for bilateral knee and back pain. She had had recurrent severe vaso-occlusive crises and acute chest syndrome in the course of her disease. ⋯ There is no known association between sickle cell disease and primary hyperparathyroidism, and this case is most probably a random occurrence. However, as emphasized by this case report, pain may also be a harbinger of other disease processes in sickle cell disease. Because management may vary, we suggest that care providers consider the diagnosis of vaso-occlusive crisis as the diagnosis of exclusion and that other etiologies for pain be envisaged in this patient population, especially in the presence of prolonged pain or unusual clinical, radiologic, or biological findings.

Randomized Controlled Trial Comparative Study
A randomized, prospective, comparison study of polyethylene glycol 3350 without electrolytes and milk of magnesia for children with constipation and fecal incontinence.
Our aim was to compare 2 laxatives, namely, polyethylene glycol 3350 without electrolytes and milk of magnesia, evaluating the efficacy, safety, acceptance, and 1-year outcomes. ⋯ In this randomized study, polyethylene glycol and milk of magnesia were equally effective in the long-term treatment of children with constipation and fecal incontinence. Polyethylene glycol was safe for the long-term treatment of these children and was better accepted by the children than milk of magnesia.

Spirometry is an important component of the National Asthma Education and Prevention Program guidelines for asthma, yet published data show variable associations between forced expiratory volume in 1 second percentage (FEV1%) predicted, symptoms and health care utilization. The objective of this analysis was to examine the association between FEV1% and future risk of exacerbations among a well-characterized population of children with asthma. ⋯ We observed a clear relationship between prebronchodilator FEV1% and important clinical outcomes. In multivariable models that simultaneously controlled for covariates of interest, age at baseline, time, previous event history, and nocturnal awakenings, a significant relationship between FEV1% and asthma symptoms and serious asthma exacerbations (oral steroids, emergency department visits, and hospitalizations) was observed. Compared with children with an FEV1% > or = 100%, children with FEV1% 80% to 99%, 60% to 79%, and < 60% were 1.3, 1.8, and 4.8, respectively, more likely to have a serious asthma exacerbation during the ensuing 4 months. CONCLUSIONS. In children with mild to moderate asthma, FEV1% predicted is independently associated with future asthma symptoms and health care utilization. Previous asthma-related hospitalizations and nocturnal symptoms also were independently associated with risk for future adverse events. FEV1 is an important component of asthma health status and asthma severity classification.

Review Case Reports
Invasive pulmonary and central nervous system aspergillosis after near-drowning of a child: case report and review of the literature.
Invasive aspergillosis is extremely rare in immunocompetent children. Here we describe the clinical, radiologic, and laboratory course of fatal invasive pulmonary and central nervous system aspergillosis in a previously healthy child after a near-drowning incident with submersion in a pond. Findings were compared with data from the literature, which is reviewed. ⋯ This delay may have contributed to the fatal course. Serial determination of serum Aspergillus galactomannan may be helpful in diagnosing invasive aspergillosis early in case of pulmonary disease after near-drowning and may contribute to an early appropriate treatment. Currently voriconazole, eventually in combination with caspofungin, should be considered as the drug of choice in the management of invasive aspergillosis after near-drowning.

Increasing evidence suggests that 10 microg/dL, the current Centers for Disease Control and Prevention screening guideline for children's blood lead level, should not be interpreted as a level at which adverse effects do not occur. Using data from a prospective study conducted in Mexico City, Mexico, we evaluated the dose-effect relationship between blood lead levels and neurodevelopment at 12 and 24 months of age. ⋯ These analyses indicate that children's neurodevelopment is inversely related to their blood lead levels even in the range of < 10 microg/dL. Our findings were consistent with a supralinear relationship between blood lead levels and neurobehavioral outcomes.
