ABSTRACT

BACKGROUND: Epidemiologic and clinical studies of Mycobacterium avium complex (MAC) pulmonary disease typically use strict ATS/IDSA definitions designed for decisions about treatment. Studies based on these criteria may exclude a substantial number of patients with true disease. We reviewed patients treated for MAC pulmonary disease at an academic medical center to propose revised definitions encompass the full spectrum of MAC pulmonary disease. METHODS: We conducted a retrospective review of patients with MAC pulmonary disease treated from 1993-2006 by pulmonary or infectious disease specialists to assess whether treated patients met current ATS/IDSA microbiologic criteria and dichotomous radiologic classification as nodular/bronchiectatic (NB) or fibrocavitary (FC) disease. We propose a revised set of definitions that include categories of both probable and definite disease to include all treated patients. We further classify patients into dichotomous clinical categories as: "primary MAC" (without antecedent lung disease) or "secondary MAC" (smoking history or antecedent lung disease). RESULTS: Among 72 treated patients, 74% were female. Median age at diagnosis was 64 years; 41(57%) met ATS/IDSA criteria and 31 (43%) did not, most often for lack of multiple positive cultures. Dichotomous radiologic criteria were met by 48 (67%) patients (36 NB, 12 FC); the remaining 24 (33%) had both NB and FC findings or other abnormalities. Nineteen (26%) were classified as primary and 53 (74%) as secondary MAC (21 COPD, 4 bronchiectasis, 44 smoking history). CONCLUSIONS: We propose revised definitions for epidemiologic and clinical studies of MAC pulmonary disease that describe the full spectrum of disease.

ABSTRACT

OBJECTIVES: Surveillance blood lead screening of refugee children resettled in Manchester, NH, in 2004 revealed that 39 (42%) of 92 children had elevated levels (>or=10 microg/dL) after resettlement. Furthermore, 27/92 children (29%) had nonelevated screening blood lead levels on arrival (BLL1) but had elevated follow-up blood lead levels 3-6 months after settlement (BLL2). The main objective was to identify risk factors for increasing lead levels among refugee children after resettlement in Manchester in 2004. PATIENTS AND METHODS: We conducted a cohort study, with completion of household interviews and home assessments for refugee families who had resettled in 2004 in Manchester, NH. Blood lead level (BLL) data were abstracted from the New Hampshire (NH) Childhood Lead Poisoning Prevention Program. To assess acute and chronic malnutrition among refugees, we used anthropometric data from International Organization of Migration documents to calculate nutritional indices. RESULTS AND DISCUSSION: Of the 93 African refugee children in 42 families who participated, 60 (65%) had been born in a refugee camp. Median age was 5.5 years at the time of BLL2 measurement. Thirty-six (39%) of the refugee children had BLL2 >or= 10 microg/dL. Liberians and those born in refugee camps had higher geometric mean BLL2 than those not Liberian or not born in camps. Younger children and children with nutritional wasting before immigrating to the United States had a greater increase in geometric mean from BLL1 to BLL2, compared to older children and those without nutritional wasting. Follow-up blood lead testing of refugee children, particularly those resettled in areas with older housing stock, as in Manchester, is important for identifying lead exposure occurring after resettlement. Increased attention to improve nutritional status of children in refugee camps and after arrival in the United States and awareness of children who were born in refugee camps should be incorporated into lead-poisoning prevention strategies.

ABSTRACT

We surveyed hospital personnel regarding their preparedness to use and their actual use of portable isolation units that were distributed to increase facilities' capacity to place patients under airborne infection isolation precautions. Although personnel reported feeling prepared to use portable isolation units, the effectiveness of the unit deployment program would be enhanced by retrofitted rooms and an improved ability to monitor negative air pressure.

ABSTRACT

We describe a case of congenital rubella syndrome with typical stigmata in an infant born in New Hampshire to Liberian refugees. The infant's clinical specimens were tested for rubella. Rubella immunity status was sought for contacts. The infant's specimen cultures grew wild-type rubella virus; serum immunoglobulin M and G were positive. Eighteen of 20 contacts were rubella-immune. Family's transit history, mother's vaccination history, and infant's estimated gestational age supported congenital infection acquired overseas. Clinicians should maintain vigilance for congenital rubella syndrome in infants with relevant stigmata, particularly those whose mothers are from countries with nonexistent or recently implemented rubella vaccination programs.
