Mothball Ingestion in the Setting of G6PD Deficiency Causing Severe Hemolytic Anemia, Methemoglobinemia, and Multiple Organ Failure in a Toddler.

Mothballs containing naphthalene or paradichlorobenzene are known to cause hemolysis and methemoglobinemia. They can also affect the other organs, including the kidneys, liver, lungs, and skeletal muscles. The involvement of 1 or 2 organs at a time has been commonly reported. However, more than 2 organ dysfunction in mothball intoxication is rare and usually indicates severe illness. The intoxication can have more pronounced symptoms in children with glucose-6-phosphate dehydrogenase (G6PD) deficiency. We report this case of a previously healthy 13-month-old patient who presented with severe hemolysis, lactic acidosis, methemoglobinemia, acute renal failure, hepatic dysfunction, and rhabdomyolysis. He required aggressive fluid resuscitation, blood transfusions, and mechanical ventilation. The underlying etiology of his illness was initially unclear; however, upon repeated questioning, the father recalled the patient chewing on a mothball 3-4 days before admission. Hence, mothball intoxication was considered the most plausible clinical diagnosis in this patient. He was given N-acetylcysteine, instead of methylene blue, because of hepatic dysfunction and the fact that G6PD deficiency could not be ruled out in the presence of acute hemolysis. The patient made a full recovery after 2 weeks of intensive care unit management. G6PD testing after 3 months confirmed the deficiency. These mothballs are available in Hawai'i, but this is the first report of such a severe presentation to our knowledge. The presence of methemoglobinemia, severe hemolysis, and thorough history-taking helped us determine the diagnosis of mothball intoxication and enabled definitive treatment.

Antibiotic Susceptibility of Bloodstream Isolates in a Pediatric Oncology Population: The Case for Ongoing Unit-specific Surveillance.

Fever in a neutropenic oncology patient requires rapid initiation of effective empiric antibiotics to prevent mortality. We evaluated the appropriateness of our current empiric antibiotic regimen by assessing local antibiotic-susceptibility patterns in our pediatric oncology patients, and comparing them to the general pediatric patterns in our hospital. All blood culture isolates from pediatric oncology patients were reviewed over a 3-year period. Gram-negative and Gram-positive organisms were reviewed separately, with antibiotic susceptibilities for all unique isolates evaluated, and antibiograms generated and compared with general pediatric patients via the Fisher exact test. A total of 84% of Gram negatives were susceptible to meropenem; all resistant organisms were Pseudomonas aeruginosa, with 50% meropenem susceptibility. A total of 91% of Gram negatives were susceptible to cefepime, including 90% of P. aeruginosa and 80% of Escherichia coli. In total, 96% of Gram positives were vancomycin-susceptible; the only resistant organism was a single enterococcal isolate. In comparison with the general pediatric population, significantly fewer pseudomonal isolates were sensitive to meropenem among the oncology population (50% vs. 89%, P=0.0034). As such, in our population, meropenem does not provide adequate monotherapy against Pseudomonas. Ongoing surveillance of antibiotic resistance in this high-risk population is warranted, to ensure appropriate empiric antibiotic usage.

Hawai'i's multiethnic adolescent and young adult survivors of childhood cancer: are their health behavior risks similar to state and national samples?

Due to toxicities associated with their malignancies and treatments, adolescent and young adult survivors of childhood cancer (AYASCC) are at high risk for developing chronic diseases. This can be compounded by a greater prevalence of unhealthy behaviors relative to similarly aged non-cancer peers. Disparities in health behaviors have been noted for Black and Hispanic AYASCC, but data on Asian American (AA) or Native Hawaiian and Other Pacific Islander (NHOPI) minorities are lacking. The purpose of this study was to help bridge these information gaps by gathering data from Hawai'i AA and NHOPI AYSCC. Telephone surveys were used to collect health behavior data from survivors 13-24 years of age (N=64); 55% of the sample was female, 77% AA or NHOPI, 63% leukemia/lymphoma survivors, and 32% overweight/obese. These were compared to state/national survey data for similarly aged individuals (Youth Risk Behavior Surveillance System data for 13-17 year olds, and Behavioral Risk Factor Surveillance System data for 18-24 year olds). While Hawai'i AYASCC had significantly lower rates of tobacco/alcohol use, a higher proportion did not eat five fruits/vegetables a day (96%) compared to state (83%) and national (78%) samples (P < .001). Although many met age-specific physical activity recommendations, 44% of <18 year olds and 29% of ≥18 year olds still failed to meet national guidelines. Low intake of fruits/vegetables and suboptimal levels of physical activity place these vulnerable, ethnic minority cancer survivors at higher risk for chronic disease. These findings underscore the need to assess and advise survivors about their diet and exercise habits as part of post-treatment care.

Treatment of Gorham-Stout disease with zoledronic acid and interferon-α: a case report and literature review.

Gorham-Stout disease is a rare disease characterized by osteolysis, angiomatosis, and soft-tissue swelling. It is a diagnosis of exclusion and has an unknown etiology. Chylothorax is a common complication of the disease that is associated with a high mortality rate. There is no standard of treatment. We report a case of a 16-year-old female with Gorham-Stout disease and recurrent pleural effusions who was successfully treated with concurrent zoledronic acid and peg-interferon α-2b.
