Provider and Caregiver Perspectives on Telehealth Assessments for Autism Spectrum Disorder in Young Children: A Multimethod DBPNet Study Exploring Equity. J Dev Behav Pediatr 2023; Publish Ahead of Print:00004703-990000000-00111. [PMID: 37315107 DOI: 10.1097/dbp.0000000000001198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 04/18/2023] [Indexed: 06/16/2023]
Abstract
BACKGROUND Telehealth uptake increased dramatically during the COVID-19 pandemic, including for autism spectrum disorder (ASD) assessment by developmental-behavioral pediatric (DBP) clinicians. However, little is known about the acceptability of telehealth or its impact on equity in DBP care. OBJECTIVE Engage providers and caregivers to glean their perspectives on the use of telehealth for ASD assessment in young children, exploring acceptability, benefits, concerns, and its potential role in ameliorating or exacerbating disparities in access to and quality of DBP care. METHODS This multimethod study used surveys and semistructured interviews to describe provider and family perspectives around the use of telehealth in DBP evaluation of children younger than 5 years with possible ASD between 3/2020 and 12/2021. Surveys were completed by 13 DBP clinicians and 22 caregivers. Semistructured interviews with 12 DBP clinicians and 14 caregivers were conducted, transcribed, coded, and analyzed thematically. RESULTS Acceptance of and satisfaction with telehealth for ASD assessments in DBP were high for clinicians and most caregivers. Pros and cons concerning assessment quality and access to care were noted. Providers raised concerns about equity of telehealth access, particularly for families with a preferred language other than English. CONCLUSION This study's results can inform the adoption of telehealth in DBP in an equitable manner beyond the pandemic. DBP providers and families desire the ability to choose telehealth care for different assessment components. Unique factors related to performing observational assessments of young children with developmental and behavioral concerns make telehealth particularly well-suited for DBP care.

Abstract
BACKGROUND Information on exclusive breastfeeding (BF) and BF initiation following bariatric surgery (BS) among obese women with diabetes mellitus (DM) and without DM (non-DM) is limited. METHODS Retrospective cohort study. Obesity was defined by BMI (kg/m2) as grade 1 (30-34.9), grade 2 (35-39.9) or grade 3 (≥40). The 65 women in the DM group (40 women with gestational, 19 with Type 2 and 6 with Type 1) was similar to 84 with non-DM in BS type: Roux-en-Y (51 vs 55%), sleeve gastrectomy (32 vs 35%), laparoscopic gastric banding (17 vs 7%) and gastro-duodenal anastomosis (0 vs 4%). RESULTS Women with DM were older (35 vs 33y), of advanced age (54 vs 27%), with higher prevalence of grade 3 obesity (66 vs 46%), chronic hypertension (31 vs 10%), delivery of late-preterm infants (23 vs 10%) and neonatal hypoglycemia (25 vs 12%). Although infant feeding intention was similar: BF (66 vs 79%), partial BF (9 vs 7%) or formula (25 vs 14%), at discharge women with DM had lower exclusive BF (29 vs 41%) and BF initiation rates (68 vs 76%) than those with non-DM. Women with grade 3 obesity (52% were DM) differed from those with grades 1-2 (34% were DM) in exclusive BF (27 vs 52%), and BF initiation rates (66 vs 86%). CONCLUSION After BS, women with DM, especially those with grade 3 obesity, had higher rates of chronic hypertension and preeclampsia and lower rates of exclusive BF and BF initiation than those who had DM but had less severe obesity.

Abstract
OBJECTIVE To compare breastfeeding (BF) initiation among 317 women with chronic hypertension (CHTN) and 106 women with CHTN superimposed on pregestational diabetes (CHTN-DM) who intended exclusive or partial BF. METHODS Retrospective cohort study of women who delivered at≥34 weeks of gestation. At discharge, exclusive BF was defined by direct BF or BF complemented with expressed breast milk (EBM) while partial BF was defined by formula supplementation. RESULTS CHTN and CHTN-DM groups were similar in prior BF experience (42 vs 52%), intention to BF exclusively (89 vs 79%) and intention to partially BF (11 vs 21%). Women in the CHTN group were younger (31 vs 33y), more likely primiparous (44 vs 27%), and delivered vaginally (59 vs 36%) at term (85 vs 75%). Women in the CHTN-DM group had higher repeat cesarean rates (32 vs 18%), preterm birth (25 vs 15%), neonatal hypoglycemia (42 vs 14%) and NICU admission (38 vs 16%). At discharge, exclusive BF rates among CHTN was higher (48 vs 19%), while rates of partial BF (34 vs 44%) and FF (18 vs 37%) were lower than in the CHTN-DM group. BF initiation (exclusive plus partial BF) occurred in 82%of CHTN and in 63% of CHTN-DM. CONCLUSION Although intention to BF was similar, BF initiation rates were higher for the CHTN compared to the CHTN-DM group. Exclusive BF was low in the CHTN and even lower in the CHTN-DM group signaling the need for targeted interventions if BF initiation rates are to be improved.

Abstract
BACKGROUND Timely delivery and magnesium sulfate (MgSO4) are mainstay in the treatment of preeclampsia with severe features (PWSF). Premature delivery, severity of illness and mother-infant separation may increase the risk for breastfeeding (BF) initiation failure. OBJECTIVE To compare BF initiation among women with late-onset PWSF treated with MgSO4 to women with late-onset preeclampsia without severe features (WOSF) who did not receive MgSO4. METHODS Retrospective study of 158 women with PWSF and 104 with WOSF who delivered at ≥34 weeks. Intention to BF, formula feed (FF) or partially BF was declared prenatally. At discharge, exclusive BF included direct BF or direct BF with expressed breast milk (EBM). RESULTS PWSF and WOSF groups were similar in age, race, and obstetric history. PWSF and WSOF differed in primiparity (65 & 51%), late preterm births (73 vs 15%), admission to NICU (44 &17%) and mother (5 & 4d) and infant (6 & 3d) hospital stay. Both groups were similar in intention to BF (80 & 84%), to FF (16 & 13%) and to partially BF (5 & 5%). At discharge, exclusive BF (37 & 39%), partial BF (33 & 31%) and FF (30 & 30%) were similar. Exclusive BF in the PWSF group was 43% direct BF, 28% direct BF and EBM and 29% EBM alone whereas in the WOSF group exclusive BF was 93% direct BF and 7% direct BF and EBM. CONCLUSION BF initiation rates for women with PWSF and WOSF were similar. EBM alone or with direct BF enabled infants in the PWSF group to exclusively BF at discharge.

Abstract
OBJECTIVE To compare multiparous women with pregestational diabetes mellitus (PGDM) with and without prior breastfeeding (BF) experience and to ascertain their infants' feeding type during hospitalization and at discharge. METHODS A retrospective cohort study of 304 women with PGDM who delivered at ≥34 weeks gestational age (GA). Prior BF experience and infant feeding preference was declared prenatally. At discharge, BF was defined as exclusive or partial. RESULTS BF experience and no experience groups were similar in diabetes type 1 and 2, race and number of pregnancies. Women with no experience had more spontaneous abortions (35 vs 27%), fewer term deliveries (51 vs 61%) and living children (median 1 vs 2). In the current pregnancy, mode of delivery: vaginal (36 & 37%), cesarean (64 & 63%), birthweight (3592 & 3515 g), GA (38 & 37 w), NICU admission (14 & 11%) and hypoglycemia (44 & 43%) were similar. Women with experience intended to BF (79 vs 46%), their infants' first feeding was BF (64 vs 36%) and had lactation consults (96 vs 63%) more often than those without experience. At discharge, women with BF experience were different in rate of exclusive BF (33 vs 11%), partial BF (48 vs 25%) and formula feeding (19 vs 64%). CONCLUSION Prior BF experience leads to better BF initiation rates while the absence of BF experience adds a risk for BF initiation failure. A detailed BF history could provide insight into obstacles that lead to unsuccessful BF experiences and may help define appropriate preventive or corrective strategies.

Abstract
OBJECTIVE To identify laboratory data that correlates with poor perinatal outcomes. METHODS A retrospective chart review of women with intrahepatic cholestasis of pregnancy (ICP), admitted for delivery between January 1, 2013 and December 31, 2017, was performed. Chi-square, student's t-test, and ANOVA statistical analysis was performed. The receiver-operator characteristic curves were plotted for the prediction of each category of perinatal outcome and the areas under the curves were determined. All p-values were two-sided, and p < 0.05 was considered statistically significant. RESULTS Analysis of the 61 ICP cases showed no occurrence of the intrauterine fetal demise (IUFD), stillbirth, abruption, or neonatal demise. ROC curve analysis revealed a statistically significant correlation between bile acid and AST levels and perinatal outcomes. A bile acid (BA) level equal to or greater than 37μmol/L strongly predicted spontaneous preterm labor in women affected by ICP with a sensitivity of 100% and specificity of 60.70% (p = 0.002). A BA level equal to or greater than 42μmol/L strongly predicted meconium-stained amniotic fluid with a sensitivity of 85.70% and specificity of 66.70% (p = 0.006). AST levels equal to or greater than 62 IU/L strongly predicted NICU admission with a sensitivity of 81.30% and specificity of 62.20% (p = 0.002). AST levels equal to or greater than 75 IU/L strongly predicted hyperbilirubinemia in the neonates with a sensitivity of 87.50% and specificity of 69.80% (p = 0.001). CONCLUSIONS There is a statistically significant correlation between elevated BA and elevated AST levels and adverse perinatal outcomes.

Abstract
PURPOSE OF REVIEW There is a perceived shortage of evidence-based treatment programs for adults on the autism spectrum. This article reviews the recent research literature on psychosocial/behavioral interventions targeting social functioning in autistic adults without intellectual disability. RECENT FINDINGS We identified only 41 peer-reviewed studies published from 1980 to 2017 that tested intervention programs focused on one or more of the behavioral components of social functioning (i.e., social motivation, social anxiety, social cognition, and social skills) in more than one adult with autism spectrum disorder (ASD). The studies demonstrated substantial variability in treatment objectives, intervention procedures, assessment methods, and methodologic quality. The results indicate a strong need for additional research to develop and rigorously test interventions for autistic adults that target the many behavioral components of social functioning and that include procedures to promote generalization of knowledge and skills to community settings.

Abstract
OBJECTIVE To ascertain the rate of in-hospital supplementation as it relates to early breastfeeding (BF) and early formula feeding (FF) and its effects on BF (exclusive and partial) at the time of discharge for infants born to women with pregestational diabetes mellitus (PGDM). METHODS Retrospective cohort investigation of 282 women with PGDM who intended to BF and their asymptomatic infants admitted to the newborn nursery for blood glucose monitoring and routine care. Early feeding was defined by the initial feeding if given within four hours of birth. RESULTS Of the 282 mother-infant dyads, for 134 (48%) early feeding was BF and for 148 (52%) early feeding was FF. Times from birth to BF and FF (median 1 hr, 0.3-6) were similar, while the time to first BF for those who FF and supplemented was longer (median 6 hr., 1-24). Ninety-seven infants (72%) who first BF also supplemented. Of these, 22 (23%) BF exclusively, 67 (69%) BF partially and 8 (8%) FF at discharge. One hundred seventeen (79%) who first FF also supplemented. Of these, 21 (18%) BF exclusively, 76 (65%) BF partially and 20 (17%) FF at discharge. CONCLUSION Regardless of the type of first feeding, the majority of infants born to women with PGDM require supplementation. Even when medically indicated, in-hospital supplementation is an obstacle, albeit not absolute, to exclusive BF at discharge. Parents should be reminded that occasional supplementation should not deter resumption and continuation of BF.

Abstract
BACKGROUND Asymptomatic infants born to women with pregestational diabetes mellitus (PGDM) are usually admitted to the well baby nursery (WBN) while those who are symptomatic or in need of specialized care are admitted to the neonatal intensive care unit (NICU). OBJECTIVE To determine if changes in the NICU admission rate of asymptomatic infants born to women with PGDM during two different epochs affected breastfeeding (BF) initiation rates. DESIGN/METHODS Retrospective cohort investigation of 386 women with PGDM and their infants who delivered in 2008-11 (epoch 1) and 457 who delivered in 2013-16 (epoch 2) at a single institution. RESULTS NICU admissions: Comparison between epoch 1 and epoch 2 showed a decrease in the number of admissions from 243 (63%) to 175 (38%) *(chi square *p < 0.05). Respiratory distress (39 and 43%) and prematurity (28 and 23%) as admission diagnoses remained unchanged. Admissions for prevention of hypoglycemia declined (32% to 21%)*. At discharge from the NICU, exclusive BF (12 to 19%)* and any BF increased (41 to 55%)* while formula feeding (FF) decreased (59 to 45%)*. Admission to the NICU remained a strong predictor of BF initiation failure (a OR 0.6, 95% , CI 0.4-0.9, p 0.005).WBN admissions: Comparison between epoch 1 and epoch 2 showed an increase in the number of admissions from 143 (37%) to 282 (62%)*. The incidence of hypoglycemia (31% and 38%) and its correction with oral feedings (76% and 71%) remained unchanged. At discharge from the WBN, exclusive BF (15 to 27%)* and any BF (52 to 62%)* increased while FF decreased (48 to 38%)*. CONCLUSIONS A decrease in the number of NICU admissions of asymptomatic infants born to women with PGDM is associated with improvements in BF initiation rates.

Abstract
OBJECTIVE To examine the effects of early breastfeeding (eBF) or early formula feeding (eFF) on hypoglycemia and on BF initiation in infants born to women with pregestational diabetes mellitus (PGDM) who intended to BF. METHODS Retrospective cohort investigation of 554 women with PGDM and their infants (IDMs) who delivered during 2008-2016. The first feeding (BF or FF) was considered early if given within 4 hours from birth. RESULTS 282 (51%) IDMs were admitted to the Well Baby Nursery. Of the 134 IDMs whose early feeding was BF, hypoglycemia affected 30% which was corrected with oral feedings in 78% of the cases. At discharge, 49% BF exclusively while 45% BF partially. Of the 148 IDMs whose early feeding was FF, hypoglycemia affected 40% which was corrected with oral feedings in 69% of the cases. At discharge, 14% BF exclusively while 48% BF partially. There were 272 (49%) IDMs admitted to the NICU. Their early feeding was BF (14%) and FF (86%). Hypoglycemia developed in 50% and 43% of these groups, respectively. Benefits of early feedings on hypoglycemia were masked by the routine use of IV dextrose infusions. At discharge, early BF led to exclusive BF in 45% and partial BF in 50% of the cases. Early FF led to exclusive BF in 17% and partial BF in 42% of the cases. CONCLUSIONS Early and continued feeding (BF preferably or FF if BF is not feasible) should be the first line of treatment for hypoglycemia. Early BF is paramount for BF initiation. Early FF is an obstacle, albeit not absolute, to BF initiation, thus it should not deter continued efforts to start or resume BF.

Abstract
The most common allergic diseases, such as rhinitis, asthma and atopic dermatitis, are sustained by allergic inflammation, the treatment of which requires anti-inflammatory activity. Among the available treatments, allergen immunotherapy (IT) has a documented impact on allergic inflammation which persists after its discontinuation and modifies the natural course of allergy. The anti-inflammatory effects of IT, and particularly of sublingual IT (SLIT), are based on the ability to modify the phenotype of T cells which, in allergic subjects, are characterized by a prevalence of the Th2 type, with production of IL-4, IL-5, IL-13, IL-17, and IL-32 cytokines. IT-induced changes result in a Th1-type response (immune deviation) related to an increased IFN-gamma and IL-2 production or in a Th2 reduced activity, through a mechanism of anergy or tolerance. It is now known that T cell tolerance is characterized by the generation of allergen-specific Treg cells, which produce cytokines such as IL-10 and TGF-beta with immunosuppressant and/or immunoregulatory activity. Recent studies suggest that the anti-inflammatory mechanism of SLIT is similar to classical, subcutaneous IT, with a prominent role in SLIT for mucosal dendritic cells. The tolerance pattern induced by Treg accounts for the suppressed or reduced activity of inflammatory cells and for the isotypic switch of antibody synthesis from IgE to IgG, and especially to IgG4. Data obtained from biopsies clearly indicate that the pathophysiology of the oral mucosa plays a pivotal role in inducing tolerance to the sublingually administered allergen.

Abstract
BACKGROUND Behavioral symptoms in individuals with autism spectrum disorder (ASD) have been attributed to abnormal neuronal connectivity, but the molecular bases of these behavioral and brain phenotypes are largely unknown. Human genetic studies have implicated PCDH10, a member of the δ2 subfamily of nonclustered protocadherin genes, in ASD. PCDH10 expression is enriched in the basolateral amygdala, a brain region implicated in the social deficits of ASD. Previous reports indicate that Pcdh10 plays a role in axon outgrowth and glutamatergic synapse elimination, but its roles in social behaviors and amygdala neuronal connectivity are unknown. We hypothesized that haploinsufficiency of Pcdh10 would reduce social approach behavior and alter the structure and function of amygdala circuits. METHODS Mice lacking one copy of Pcdh10 (Pcdh10+/-) and wild-type littermates were assessed for social approach and other behaviors. The lateral/basolateral amygdala was assessed for dendritic spine number and morphology, and amygdala circuit function was studied using voltage-sensitive dye imaging. Expression of Pcdh10 and N-methyl-D-aspartate receptor (NMDAR) subunits was assessed in postsynaptic density fractions of the amygdala. RESULTS Male Pcdh10+/- mice have reduced social approach behavior, as well as impaired gamma synchronization, abnormal spine morphology, and reduced levels of NMDAR subunits in the amygdala. Social approach deficits in Pcdh10+/- male mice were rescued with acute treatment with the NMDAR partial agonist d-cycloserine. CONCLUSIONS Our studies reveal that male Pcdh10+/- mice have synaptic and behavioral deficits, and establish Pcdh10+/- mice as a novel genetic model for investigating neural circuitry and behavioral changes relevant to ASD.

Abstract
OBJECTIVE To compare neonatal outcomes (including breastfeeding (BF) initiation) of 170 macrosomic IDM with that of 739 macrosomic nIDM. DESIGN/METHODS Retrospective cohort investigation of all macrosomic infants born consecutively over a four-year period (2008-2011). Macrosomic (birth weight ≥4000 g) IDM included 100 infants whose mothers had gestational diabetes and 70 whose mothers had pregestational diabetes. RESULTS IDM were more likely to be delivered by cesarean to obese women while nIDM were more likely to be delivered vaginally to younger women with a higher level of education. Ethnic distribution (60% white, 20% black, 10% Hispanic and 10% Asian or African) was similar in each group. Forty-nine percent of IDM and 7% of nIDM required NICU admission. Respiratory disorders (mainly TTNB) affected 21% of IDM and 3% of nIDM while hypoglycemia was observed in 36% of IDM and 15% of nIDM. Of the 35 IDM delivered vaginally, 10 were complicated by shoulder dystocia without injury. Conversely, 70 of the 458 nIDM delivered vaginally experienced shoulder dystocia that resulted in 6 limb fractures and 3 brachial plexus injuries. On arrival to labor and delivery, 75% of all women intended to BF; however, at the time of discharge, 65% of women with diabetes and 92% of those without diabetes who intended to BF had initiated BF. CONCLUSIONS Both macrosomic IDM and macrosomic nIDM are at risk for significant morbidities. Macrosomic IDM carry a higher risk for NICU admissions, leading to maternal-infant separation, and lower BF initiation rates.

Abstract
BACKGROUND In the US, at the time of discharge from the hospital, 79% of women had initiated breastfeeding. Intention to breastfeed is a strong predictor of breastfeeding initiation; however, we reported initiation failure in 45% of women with pregestational diabetes who intended to breastfeed. Information regarding intention and initiation among women with other high risk obstetrical conditions (HROB) remains scarce. OBJECTIVE To ascertain demographic and clinical factors associated with breastfeeding initiation failure among women with HROB conditions who intended to breastfeed. METHODS The study population is comprised of 89 women with diabetes (DM), 57 who were receiving treatment for substance abuse (SA), 51 women diagnosed with miscellaneous (MISC) conditions and 32 with history of preterm labor/delivery (PTL/D). Intention to exclusively breastfeed or in combination with formula (breastfed/FF) was ascertained prenatally. Breastfeeding was considered initiated if at discharge ≥50% of their infant feedings were maternal milk. Statistics include chi-square, Wilcoxon's and logistic regression (p < 0.05). RESULTS Of all women, 59% initiated any breastfeeding. Intention to breastfeed/FF, lack of mother-infant contact during the first hour following birth and limited lactation consultation were predictive of initiation failure. The odds of initiation failure were 2.3 times higher among women who wished to breastfeed/FF as compared to those who wished to exclusively breastfeed. Women from the SA group had lower rates of initiation failure than the other three HROB groups. CONCLUSION Intention to breastfeed among women with diverse HROB conditions is similar to that of the general population; however, initiation rates are disappointingly low. Intention to exclusively breastfeed results in fewer initiation failures. Prenatal intention to combine breast and formula feeding characterize women who may benefit from specific educational programs.

Abstract
BACKGROUND In the United States, breastfeeding initiation (BFI) is reported for 75% of all live births; however, little information is available regarding mothers affected by gestational diabetes mellitus (GDM). OBJECTIVE To examine feeding practices and factors associated with BFI in women with GDM and their infants. METHODS A total of 303 GDM (58 late preterm and 245 term) pregnancies were studied. Infant feeding preference was ascertained on admission to labor and delivery. Variables known to influence BFI including maternal age, smoking, obesity, racial and educational characteristics were assessed. RESULTS On admission 188 women intended to BF, 60 intended to feed formula and 55 were undecided. None of the women who wished to feed formula and 27% of the originally undecided later initiated BF. Regardless of feeding preference 163 (54%) of all mothers initiated BF. Similar BFI rates were found for 176 Class A1 and 127 class A2 women. Logistic regression analysis showed that intention to BF was the most significant predictor of BFI. Factors associated with BFI failure included African American race, lower education, smoking, obesity and admission to NICU. Following delivery 264 (87%) infants received well baby care while 39 (13%) were admitted to the NICU. Among 188 women who intended to BF, BFI involved 81% of 160 infants receiving well baby care and 61% of the 28 admitted to the NICU. CONCLUSIONS More than half of women with GDM, who intended to BF, initiated BF. BFI failure remains associated with race, lower education level, smoking, obesity, preference for formula feeding and admission to NICU.

Abstract
OBJECTIVE Each year in the US ∼50 000 neonates receive inpatient pharmacotherapy for the treatment of neonatal abstinence syndrome (NAS). The objective of this study is to compare the safety and efficacy of a traditional inpatient only approach with a combined inpatient and outpatient methadone treatment program. STUDY DESIGN Retrospective review (2007 to 2009). Infants were born to mothers maintained on methadone in an antenatal substance abuse program. All infants received methadone for NAS treatment as inpatient. Methadone weaning for the traditional group (75 patients) was inpatient, whereas the combined group (46 patients) was outpatient. RESULT Infants in the traditional and combined groups were similar in demographics, obstetrical risk factors, birth weight, gestational age (GA) and the incidence of prematurity (34 and 31%). Hospital stay was shorter in the combined than in the traditional group (13 vs 25 days; P<0.01). Although the duration of treatment was longer for infants in the combined group (37 vs 21 days, P<0.01), the cumulative methadone dose was similar (3.6 vs 3.1 mg kg(-1), P=0.42). Follow-up information (at least 3 months) was available for 80% of infants in the traditional and 100% of infants in the combined group. All infants in the combined group were seen ≤72 h from hospital discharge. Breastfeeding was more common among infants in the combined group (24 vs 8% P<0.05). Following discharge there were no differences between the two groups in hospital readmissions for NAS. Prematurity (34 to 36 weeks GA) was the only predictor for hospital readmission for NAS in both groups (P=0.02, OR 5). Average hospital cost for each infant in the combined group was $13 817 less than in the traditional group. CONCLUSION A combined inpatient and outpatient methadone treatment in the management of NAS decreases hospital stay and substantially reduces cost. Additional studies are needed to evaluate the potential long-term benefits of the combined approach on infants and their families.

Abstract
Objective:Develop a cross-cultural translation, Swedish to Spanish, of TOOL questionnaire - a previously validated instrument to assess the impact of adverse effects (AE) on the health utilities and health related quality of life (HRQoL) in patients with schizophrenia and bipolar disorder.Methods:TOOL questionnaire has 8 attributes and 4 levels per domain: mood (anxiety and depression), function capabilities, and AE frequently associated with antipsychotics (fatigue-weakness, weight gain, stiffness-tremor, physical restlessness, sexual dysfunction, and vertigo-nausea). Firstly, 4 independent translators carried out the forward-backward translations. Next, draft version was reviewed by an experts panel (5 psychiatrists & 1 GP specialized in HRQoL) and tested in 40 stable patients (20 schizophrenic & 20 bipolar). Comprehension and importance (C/I) of each item were evaluated by a Likert scale ranging from 0 (lowest level) to 4 (highest level).Results:3 items should be modified to facilitate comprehension: mood, physical restlessness and vertigo-nausea. However, C/I of items mean scores were respectively: mood (3.50/ 2.37); function capabilities (2.58/ 2.03); fatigue-weakness (3.58/ 2.55); weight gain- (3.75/ 2.87); stiffness-tremor (3.65/ 2.61); restlessness (3.37/ 2.62); sexual dysfunction (3.39/ 2.51) and vertigo-nausea (3.56/ 2.44). Only 2 patients (5%) were unable to complete the questionnaire. Internal consistency was high (Cronbach α= 0.87) and neither item ceiling nor floor effects were found.Conclusions:The Swedish TOOL questionaire was culturally adapted into Spanish. Psychometric analyses are needed to validate this measure in Spain. A multtiatribute utility fuction should be estimated to evaluate AE by using a patients"centered perspective.

Abstract
BACKGROUND Indomethacin prophylaxis or expectant treatment are common strategies for the prevention or management of symptomatic patent ductus arteriosus (sPDA). OBJECTIVE To compare the clinical responses of extremely low birth weight (ELBW) infants to indomethacin prophylaxis with that of other infants who were managed expectantly by being treated with indomethacin or surgically only after an sPDA was detected. METHODS Retrospective cohort investigation of 167 ELBW infants who received indomethacin prophylaxis (study) and 167 ELBW infants (control) treated expectantly who were matched by year of birth (1999 to 2006), birth weight, gestational age (GA) and gender. RESULTS Mothers of the two groups of infants were comparable demographically and on the history of preterm labor, pre-eclampsia, antepartum steroids and cesarean delivery. Study and control infants were similar in birth weight, GA, low 5 min Apgar scores, surfactant administration, the need for arterial blood pressure control, bronchopulmonary dysplasia and neonatal mortality. Necrotizing enterocolitis, spontaneous intestinal perforations, intraventricular hemorrhage grade III to IV, periventricular leukomalacia and stage 3 to 5 retinopathy of prematurity occurred also with similar frequency in both groups of infants. In the indomethacin prophylaxis group, 29% of the infants developed sPDA, and of them 38% responded to indomethacin treatment. In the expectantly treated group, 37% developed sPDA, and of them 59% responded to indomethacin treatment. Overall, surgical ligation rate for sPDA was similar between both groups of patients. CONCLUSION In our experience, indomethacin prophylaxis does not show any advantages over expectant early treatment on the management of sPDA in ELBW infants. Although no deleterious effects were observed, prophylaxis exposed a significant number of infants who may have never developed sPDA, to potential indomethacin-related complications.

Abstract
BACKGROUND Antenal indomethacin reportedly decreases the responses of a symptomatic patent ductus arteriosus (sPDA) to postnatal indomethacin treatment. Whether a similar exposure affects the responses to indomethacin prophylaxis is unknown. OBJECTIVE To evaluate the clinical responsiveness of ductus arteriosus to indomethacin prophylaxis and to the treatment of sPDA in extremely low birth weight (ELBW) infants following indomethacin tocolysis. METHODS Retrospective cohort study of 58 ELBW infants whose mothers received indomethacin tocolysis (study) and 58 ELBW infants whose mothers did not (controls), matched by gender, gestational age (GA), birth weight and postnatal sPDA management (prophylaxis or early treatment). RESULTS Indomethacin was used as a tocolytic at a median dose of 250 mg, for a duration of 2 days, and ending 1 day before delivery. Study and control mothers were comparable in demographics, antenatal steroid use, cesarean delivery, but were different in the incidence of preeclampsia and preterm labor. Study and control infants were similar in birth weight, GA, indomethacin prophylaxis, early sPDA treatment, mortality, necrotizing enterocolitis, severe intraventricular hemorrhage and stage 3-5 retinopathy of prematurity. Seventeen of 43 study and 16 of 43 control infants who received indomethacin prophylaxis developed sPDA and were combined with early treatment sPDA infants (15 to each group). Two of 32 study and two of 31 control infants underwent surgical ligation whereas the remaining were treated with indomethacin. Sixteen of 30 (53%) and 13 of 29 (45%) were successfully treated and did not require ligation. Study infants were divided according to their mothers' indomethacin total dose (28 infants received <or=225 mg and 30 infants received >225 mg). Both subgroups were demographically and clinically comparable and their response to indomethacin prophylaxis and treatment were similar. CONCLUSION In ELBW infants, exposure to indomethacin tocolysis does not affect the clinical responsiveness of the ductus arteriosus to prophylaxis or that of the sPDA to indomethacin treatment.

Abstract
BACKGROUND Monochorionic monoamniotic twins (MoMo) occur in one of 10,000 pregnancies. Cord entanglement, malformations, twin-to-twin transfusion syndrome (TTS) and prematurity are responsible for their high perinatal morbidity and mortality. OBJECTIVE To report our experience with 36 sets of MoMo twins (1990 to 2005) and to provide updated information for counseling. METHODS Chorionicity was determined by placental examination, gestational age and TTS clinically and by sonography. Intrauterine growth restriction (IUGR) was diagnosed with a twin-specific nomogram. RESULTS Cord entanglement was observed in 15 pregnancies, but only one twin with entanglement and a true knot, experienced related morbidity. Four of 71 live births were IUGR. Malformations were diagnosed prenatally (one hypoplastic left heart and one body stalk) and postnatally (one vertebral anomalies-anal atresia-tracheoesophageal fistula-renal defect (VATER) and two lung hypoplasias). Twin-to-twin transfusion syndrome affected three sets of twins. Five twin sets delivered before 31, 19 sets at 31 to 32 and 12 sets at 33 to 34 weeks. Six of 71 (8%) twins died (four malformations, one TTS and one 26 weeks premature). Head ultrasounds in 59 of 65 survivors showed two (3%) periventricular leukomalacia, five (9%) Grade I-II intraventricular hemorrhage and 52 (88%) normal. CONCLUSIONS Monochorionic monoamniotic twins remain a group at risk for cord entanglement, congenital malformations, TTS and prematurity. Although their neonatal mortality and morbidity is high, outcomes for survival are better than anticipated.

Abstract
Bartonellosis remains a major problem in Peru, but many contemporary aspects of this disease have not been adequately described. We examined the cases of 145 symptomatic patients in Lima, Peru, in whom bartonellosis was diagnosed from 1969 through 1992, including 68 patients in the acute (hematic) phase and 77 patients in the eruptive (verruga) phase. In modern Peru, symptomatic patients who have acute-phase bartonellosis typically present with a febrile illness and systemic symptoms caused by profound anemia; most patients respond successfully to treatment with chloramphenicol. Patients who have eruptive-phase bartonellosis most often present with cutaneous verrugas but may have less specific symptoms, such as fever and arthralgias; diagnosis can be confirmed in such patients by Western immunoblotting, and most patients appear to respond to treatment with rifampin.

Abstract
OBJECTIVE Tracheal aspirates (TAs) from mechanically ventilated very low birth weight (VLBW) infants are frequently obtained during the evaluation of suspected sepsis, tracheitis, or ventilator-associated pneumonia (VAP). Purulence and bacteria in Gram stain of bronchopulmonary secretions are considered signs of respiratory infection, and medical decisions are made on the assumption that they are predictors of positive bacterial tracheal cultures (TCs). The purpose of this retrospective investigation was to establish the relationship of purulence and bacteria in TA from ventilated VLBW infants with positive TC and to identify its clinical significance. STUDY DESIGN One hundred and seventy consecutively born VLBW infants (1996 to 1998) who remained on mechanical ventilation longer than 1 week were studied. Demographic, laboratory, and clinical data were obtained from hospital medical records. Purulence, defined by the number of polymorphonuclear leukocytes (PMNs) per low power field (LPF), was reported as light (<25 PMNs/LPF) or moderate/heavy (>or=25 PMNs/LPF) for every TA. RESULTS Purulence was absent in 469 of 646 (72%) TA taken from 170 infants. Light purulence was present in 17% and moderate/heavy purulence in 11%. TCs were positive in 58% of non-purulent, 94% of light, and 100% of moderate/heavy purulent TA. Bacteria on Gram stain were present in 12% of non-purulent, 70% of light purulent, and 83% of moderate/heavy purulent TA. Moderate/heavy purulence in TA was predictive of a positive TC with Gram-negative bacilli (GNB) with 70% sensitivity, 100% specificity, 100% positive predictive value, and 67% negative predictive value. Purulence in TA, as well as GNB airway colonization, became more frequent as mechanical ventilation progressed and was not associated with a particular GNB species. There were 79 infants who never had purulent TA and 91 who, at some time during the hospitalization, did. At the time of first purulent TA, 65 (71%) of 91 infants were asymptomatic. Twenty-six infants (29%) had clinical deterioration for which they underwent sepsis work-up. Three had blood stream infection, 5 VAP, 5 tracheitis, and 13 respiratory complications of non-infectious etiology. Four of five VAP infants died; all others survived. CONCLUSION In VLBW infants, purulence in TA is associated with prolonged endotracheal intubation and is temporally related to GNB airway colonization. At the time of the first purulent TA, the majority of mechanically ventilated VLBW infants are asymptomatic. Only a few symptomatic VLBW infants had nosocomial respiratory infection. Understanding the clinical significance of purulence and GNB in TA from this unique patient population is important for management and prognosis, and it may decrease concern for infection and the associated use of antibiotics.

A comparison of two airway suctioning frequencies in mechanically ventilated, very-low-birthweight infants. Respir Care 2001; 46:783-8.

Abstract
INTRODUCTION Endotracheal suctioning of mechanically ventilated, very-low-birthweight infants for removal of respiratory secretions can be associated with morbidity. Routine endotracheal suctioning is inadvisable, but the safe minimum endotracheal suctioning frequency for prevention of airway obstruction has not been determined. HYPOTHESIS Decreasing suctioning frequency from every 4 hours to every 8 hours (plus as needed) would have no clinically important effect on the primary outcomes (nosocomial bloodstream infection [BSI], ventilator-associated pneumonia [VAP], and bacterial airway colonization) or secondary outcomes (reintubation rates, need for postural drainage, severity of bronchopulmonary dysplasia [BPD], neonatal mortality, duration of mechanical ventilation, and duration of hospitalization). METHODS We conducted a sequential retrospective study of 90 very-low-birthweight infants who were mechanically ventilated for longer than 7 days and who underwent endotracheal suctioning every 4 hours (plus as needed) and 90 similar infants who underwent endotracheal suctioning every 8 hours (plus as needed). Two-pass endotracheal suctioning used during the study period required predetermined measurement of the suction catheter and prior instillation of saline. RESULTS The 2 treatment groups were similar in demographic and clinical characteristics, including survival (90% and 85%), age at time of death (28 and 33 d), mean birthweight (926 and 934 g), gestational age (27 and 27 wk), duration of ventilation (29 and 27 d), and duration of stay (55 and 53 d). Regardless of suctioning frequency, airway colonization with Gram-positive cocci occurred in the majority of patients by 2 weeks of life. Forty-three percent of the infants suctioned every 4 hours and 44% of those suctioned every 8 hours became airway colonized with Gram-negative bacilli. No Gram-negative bacilli species was more likely to be associated with either treatment group. VAP was diagnosed in 5 of the infants suctioned every 4 hours and in 9 of the infants suctioned every 8 hours. Nosocomial BSI occurred in 18 of the infants suctioned every 4 hours and in 21 of the infants suctioned every 8 hours. The difference in incidence of VAP and BSI was due to a epidemic that started before the change in suctioning frequency. During hospitalization, approximately one fourth of the patients in each group required postural drainage and were reintubated 11 and 10 times per 100 ventilator days, respectively. A comparable number of infants in each group developed severe BPD and were discharged home on oxygen. Suctionings per patient per ventilator day were 6 for the group suctioned every 4 hours and 4 for the group suctioned every 8 hours (p < 0.01). CONCLUSIONS A low-frequency suctioning regimen (every 8 hours plus as needed) can be implemented without increasing the incidence of nosocomial BSI, VAP, bacterial airway colonization, frequency of reintubation, need for postural drainage, severity of BPD, neonatal mortality, duration of mechanical ventilation, or duration of hospitalization. Although the minimum suctioning frequency for removal of unwanted respiratory secretions is yet to be established, a substantial reduction in endotracheal suctioning frequency appears to be safe.

Abstract
PURPOSE To study retrospectively the incidence of ventilator-associated pneumonia (VAP) at the time of Pseudomonas aeruginosa nosocomial bloodstream infection (BSI) and at the time of P aeruginosa airway colonization. MATERIALS AND METHODS Fifteen very low-birth-weight infants who had P aeruginosa BSI and 33 others who did not but who had P aeruginosa airway-colonization were studied. We correlated clinical data, blood cultures (BCs), and tracheal cultures (TCs) with radiologic findings from radio-graphs taken within 2 days before, the day of, and 1 day after BCs or TCs were first positive for P aeruginosa. Chest radiographs were graded by using semiquantitative scores for bronchopulmonary dysplasia and for pneumonia. RESULTS Mean birth weight, gestational age, and age when BC or TC became positive were similar for patients with BSI and colonization. At the time of BSI, 2 infants had airway colonization with P aeruginosa; the TCs of the remaining 13 grew P aeruginosa as a new pathogen. Thirteen of 15 patients with BSI, but none of 33 infants with colonization, died within 2 days of positive BC. VAP was diagnosed in 13 of 15 patients with BSI and in 3 of 33 infants with colonization. CONCLUSION Mechanically ventilated very low-birth-weight infants whose TCs yield P aeruginosa but whose BCs remain negative infrequently have VAP are presumed airway-colonized and are expected to survive. Conversely, VAP is likely to be found when BCs and TCs simultaneously grow P aeruginosa, and high mortality is anticipated.

Abstract
BACKGROUND Gram-negative bacillary (GNB) airway colonization in mechanically ventilated newborns is associated with morbidity and mortality, which may be reduced if systemic antimicrobial therapy eradicates GNB from the airway. Efforts to do so in adults have met with variable success; similar experiences in newborns have not been reported. METHODS From 1991 through 1998, 531 very low-birth-weight infants were mechanically ventilated longer than 2 weeks. The study group was 106 infants with GNB airway colonization. Sixty-four other neonates in whom GNB nosocomial bloodstream infections developed served as antibiotic treatment outcome control. RESULTS Isolated from the airway were enteric (70 cases) and environmental (36 cases) GNB. Gentamicin alone or with ceftazidime (79), ceftazidime (11), piperacillin in combination with tazobactam or tobramycin (8), and tobramycin, in combination with ampicillin/sulbactam or mezlocillin (8) were the antimicrobials selected. Systemic antibiotics failed to eradicate GNB colonization in 97% of the cases. Six of the 106 infants with airway colonization died for reasons unrelated to infection. Sixty-four infants experienced 67 bloodstream infections as a result of enteric (53) and environmental (14) GNB. Gentamicin alone (23), with ceftazidime (26), or with clindamycin or ampicillin/sulbactam (9), piperacillin with tazobactam or tobramycin (3) and ceftazidime alone (6) were the antimicrobials selected. Survival occurred in 84% of the 67 nosocomial bloodstream infections. CONCLUSIONS Systemic antibiotics do not consistently eradicate GNB from the airway of mechanically ventilated newborns, therefore its empirical use for prophylaxis or treatment of airway colonization should be discouraged.

Abstract
OBJECTIVE To determine whether ventilated, low birth weight infants treated with closed versus open tracheal suction in a neonatal intensive care unit (NICU) differ as to airway bacterial colonization, nosocomial pneumonia, bloodstream infection (BSI), incidence and severity of bronchopulmonary dysplasia (BPD), neonatal mortality, frequency of suction, reintubation, and nurse preference. STUDY DESIGN A total of 175 low birth weight infants (< or = 1250 gm) consecutively born (1997 to 1999), intubated, and ventilated in the delivery room were randomized on admission to the NICU to a closed (Trach Care MAC) or open suction group. Closed multi-use catheters were changed daily; open catheters were changed after every use. Two-pass endotracheal suctioning (both groups) was performed every 8 hours or as needed. Side-port connectors were not used; thus open suction required disconnection from ventilators. Tracheal aspirate cultures were obtained on admission and weekly thereafter. Nosocomial BSI (occurring after 48 hours of life) was documented by positive blood cultures. Radiographs taken before, during, and after tracheal aspirate cultures or BSIs were graded using a semiquantitative system for pneumonia and a modified score for BPD. Nurse preference regarding suction method was recorded. RESULTS Of the original 175 patients, 10 (5 from each group) died and 32 others (16 form each group) were extubated at or before 7 days of life. The study population comprised 67 patients in the closed group and 66 in the open group who were ventilated longer than 1 week. Groups were not statistically different in terms of demographic and clinical characteristics, such as birth weight (837 vs 876 gm), ventilation (27 vs 26 days), and length of stay (49 vs 40 days). Airway colonization with Gram-positive cocci occurred in the majority of patients by 2 weeks of life, regardless of group. A total of 39% of infants in the closed group and 44% of infants in the open group became airway colonized with Gram-negative bacilli; differences were statistically significant. No Gram-negative bacilli species was more likely to be associated with either suction. Nosocomial pneumonia was diagnosed in five patients from each group. Nosocomial BSIs occurred in six closed suction infants and five open suction infants. A comparable number of infants in each group developed severe BPD and were discharged from the hospital on oxygen. A total of 28% of closed suction patients and 27% of open suction patients died. Infants in the closed versus open group were suctioned on average 4.4 and 4.1 times per day and were reintubated 9.7 and 8.6 times per 100 ventilator days, respectively. A total of 40 of 44 NICU nurses considered closed suction to be easier to use, less time-consuming, and better tolerated by the patient. CONCLUSIONS Closed suction obviates the physiological disadvantage of ventilator disconnection without increasing the rate of bacterial airway colonization, frequency of endotracheal suction and reintubation, duration of mechanical ventilation, length of hospitalization, incidence of nosocomial pneumonia, nosocomial BSI, severity of BPD, and neonatal mortality. Although slightly more expensive, closed suction is perceived by nursing staff to be easier, less time-consuming, and better tolerated by small premature infants requiring mechanical ventilation for > or = 1 week.

Abstract
OBJECTIVE To assess the prevalence of gram-positive coccal (GPC), gram-negative bacillary (GNB), and fungal blood-stream infections (BSIs) during a 12-year period in which a consistent antibiotic treatment protocol was in place; to evaluate the efficacy of these antibiotic policies in relation to treatment, to the emergence of bacterial or fungal resistance, and to the occurrence of infection outbreaks or epidemics. STUDY DESIGN Case series. METHODS Demographic, clinical, and bacteriological information from 363 infants born during 1986 through 1991 and 1992 through 1997 who developed 433 blood-culture-proven BSIs was analyzed. Early-onset BSIs were defined as those infections discovered within 48 hours of birth, and late-onset BSIs as those that occurred thereafter. Suspected early-onset BSIs were treated with ampicillin and gentamicin, and suspected late-onset BSIs with vancomycin and gentamicin. Antibiotics were changed on the basis of organism antimicrobial susceptibility. RESULTS Early-onset BSIs were noted in 52 of 21,336 live births and 40 of 20,402 live births during 1986 through 1991 and 1992 through 1997, respectively. GPC (83% due to group B streptococcus [GBS]) accounted for approximately one half of early-onset BSI cases and GNB (68% Enterobacteriaceae) for the remainder. Early-onset GBS declined from 24 to 11 cases (P=.04) and late-onset BSI increased from 111 to 230 cases (P<.01) from the first to the last study period. Sixty-eight percent of late-onset BSIs were due to GPC (primarily coagulase-negative Staphylococcus), 18% to GNB, and 14% to fungus. Over the study period, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, and Pseudomonas aeruginosa isolated from the newborn intensivecare unit (unlike those strains from other hospital units) remained fully susceptible to ceftazidime and gentamicin. Although the hospitalwide prevalence of methicillin-resistant Staphylococcus aureus increased, all 17 newborn BSI cases were due to methicillin-sensitive strains. Prevalence of methicillin-resistant coagulase-negative Staphylococcus increased, although all strains remained vancomycin-susceptible, as did the 16 Enterococcus faecalis isolates. All fungi recovered (from 48 patients) were susceptible to amphotericin. CONCLUSION We observed a decrease in the prevalence of early-onset BSIs due to GBS and an increase in late-onset BSIs due to GPC, GNB, and fungi. The combination of ampicillin and gentamicin for suspected early-onset BSIs and vancomycin and gentamicin for late-onset BSIs has been successful for treatment of individual patients without the occurrence of infection outbreaks or the emergence of resistance. Controlled antibiotic programs and periodic evaluations based on individual unit and not on hospitalwide antibiograms are advisable.

Abstract
One of the applications developed within the EU-funded projects TESEMED and TESEMED-II is a program for the information and continuous training of community pharmacists, with the aim to empower them as advisors of the citizens about self-medication topics. Several programs are being developed on the basis of ad-hoc developed protocols about minor ailments (currently, cold and flu, haemorrhoids, constipation and cough). Each program includes three modules: a hypertextual version of the protocol, an interactive scheme of it, and an educational tool called Encounter Simulator, that trains the pharmacist about the protocol by means of simulated pharmacist-customer interactions. The testing of these applications with 84 community pharmacists offers positive results in terms of expectations, program characteristics and perceived usefulness.

Abstract
BACKGROUND A preterm infant was found to have total parenteral nutrition (TPN) ascites after infusion through a low umbilical vein catheter (UVC). Objective. To evaluate the clinical and imaging findings of neonates with TPN ascites after infusion through UVCs. MATERIALS AND METHODS Eight patients with TPN ascites were identified over three years. Charts were abstracted for clinical data. Plain-film, ultrasound (US), and contrast studies through the UVCs were examined to determine UVC placement, presence of liver injury, and confirmation of intraperitoneal extravasation from the UVC. RESULTS All eight patients with TPN ascites presented with hypotension and abdominal distension. All had UVCs overlying the liver on plain film. Catheters were in place a mean of 8.9 days prior to TPN extravasation. US in four patients showed hepatic parenchymal damage around the UVC tip. Contrast studies in six patients showed intraperitoneal spill. CONCLUSION While low UVC placement may sometimes be clinically unavoidable, TPN administered through abnormally positioned UVCs is not without risk.

Abstract
The purpose of this study was to determine whether doubling the lactose concentration in formula for preterm infants lowers the fraction of lactose digested and/or increases the fraction of lactose fermented. Six preterm infants, 31 to 36 weeks' postconceptional age, were fed a standard preterm formula (carbohydrate is 50% lactose and 50% glucose polymer)(SC) and/or the same volume of formula modified to contain lactose as the sole carbohydrate (LAC). Relative lactose digestion during the LAC formula feeding compared with SC formula feeding was measured by using a stable isotope approach for quantifying the fractional contribution of formula lactose to plasma glucose enrichment. Relative lactose digestion was 0.98 +/- 0.17 (range, 0.70 to 1.19). Fractional fermentation of lactose was estimated from breath H2 excretion (0.52 +/- 0.34 during LAC feeding and 0.23 +/- 0.22 during SC feeding, P = .11). The rate of breath H2 excretion was much higher with LAC (1.34 +/- 0.98 mL/h) than with SC (0.27 +/- 0.29, P = .029). In conclusion, doubling the lactose concentration had only modest effects on fractional lactose digestion. Increased breath H2 excretion with LAC may relate to fermentation of nonlactose sugar or to ill-defined changes in colonic physiology or motility, which could enhance colonic fermentation of malabsorbed sugar by H2-producing bacteria.

Abstract
OBJECTIVE The objective of the study was to characterize the changes that occur in chest radiographs at the time of gram-negative bacilli (GNB) nosocomial bloodstream infection (BSI) and to determine the contribution of bronchopulmonary dysplasia (BPD) and airway gram-negative bacterial pathogens to the clinical diagnosis of GNB nosocomial pneumonia. STUDY DESIGN This retrospective investigation involved 41 BSI infants (study group) and 50 GNB airway colonized infants who had sepsis workup with negative blood cultures (control group). We correlated clinical findings (95 blood and 305 tracheal aspirate (TA) cultures) with radiographic findings noted within 2 days before, the day of, and the day after blood cultures. Two radiologists independently graded 258 films using a modified score for BPD and a semiquantitative score ("probable," "possible," or "unlikely") for pneumonia. RESULTS Mean birth weight was 1057 gm and 1044 gm for the study and control groups, respectively. Of the study population, 54% were male, 21% were black, 89% received surfactant, 79% received dexamethasone, and 88% survived. Average age at the time of blood cultures for both groups was 23 days. Most common isolates from blood and TA were Klebsiella pneumoniae, Enterobacter cloacae, Escherichia coli, and Pseudomonas aeruginosa. Eight BSI infants died, mainly as a result of P. aeruginosa and K. pneumoniae; three control patients also died. Radiological findings were that BPD scores did not change in relation to BSI and were similar between study and control groups. Of the BSI patients, 21 presented with newly positive TA at the time of positive blood culture; "probable" or "possible" pneumonia was diagnosed in 18 of them. Their BPD scores were higher than those of the remaining BSI patients, of whom seven were already airway colonized, nine had negative TAs, and four were not intubated. Only one of these 20 patients had "possible" pneumonia noted on chest x-ray films. CONCLUSION Radiographic signs of air space disease accompanied by the recovery of GNB respiratory pathogens from the blood and from a previously uncolonized airway strongly support the clinical diagnosis of GNB nosocomial pneumonia. Radiological signs of BPD are stable in relation to nosocomial BSI caused by GNB, but BPD radiological scores are higher among infants who also had a newly acquired respiratory GNB. BSI, new respiratory tract GNB, and BPD are critical associations for the clinical interpretation of radiographic changes in the ventilated newborn.

Abstract
OBJECTIVE To describe the clinical outcome of infants born to mothers with gestational diabetes mellitus (GDM) and preexisting insulin-dependent diabetes mellitus (IDDM). SETTING A tertiary care regional perinatal center with a specialized diabetes-in-pregnancy program. DESIGN Case series. RESULTS Five hundred thirty infants were born to 332 women with GDM and 177 women with IDDM. Thirty-six percent of these 530 newborns were large for gestational age, 62% were appropriate for gestational age, and only 2% were small for gestational age. Seventy-six (14%) of all infants were born before 34 weeks' gestation, 115 (22%) between 34 and 37 weeks of gestation, and 339 (64%) at term. Two hundred thirty-three infants (47%) were admitted to the neonatal intensive care unit due to respiratory distress syndrome (RDS), prematurity, hypoglycemia, or congenital malformation. Hypoglycemia (more common among infants of maternal diabetic classes C through D-R) was documented in 137 (27%) of all newborns. One hundred eighty-two infants (34%) had RDS of varying severity. Polycythemia (5% of infants), hyperbilirubinemia (25%), and hypocalcemia (4%) were other morbidities present. Two hundred forty-four infants were admitted for routine care and enteral feedings. Forty-three of these newborns required subsequent transfer to the neonatal intensive care unit for treatment of hypoglycemia (16 cases), RDS (19 cases), or both (8 cases). Routine care failures were more common among infants whose mothers had advanced diabetes, but less frequent among breast-fed infants. CONCLUSIONS With modern management, fewer morbidities can be expected in infants of diabetic mothers. Those infants born to women with IDDM remain at risk for hypoglycemia, which can be treated in one half of the cases by enteral feedings alone. The majority of cases of RDS are mild and require short admissions to special care nurseries. Optimal care of infants of diabetic mothers is based on prevention, early recognition, and treatment of common conditions. Severe congenital malformations, significant prematurity, RDS, recurrent hypoglycemic episodes, and asymptomatic infants of women with advanced IDDM should be admitted to special care nurseries. Breast-feeding among women with GDM and IDDM should be encouraged.

Bacterial and Ureaplasma colonization of the airway: radiologic findings in infants with bronchopulmonary dysplasia. J Perinatol 1997; 17:428-33.

Abstract
OBJECTIVE We designed this retrospective study to compare radiologic findings in premature infants with bronchopulmonary dysplasia (BPD) in whom gram-positive cocci (GPC), gram-negative bacilli (GNB), or Ureaplasma urealyticum were colonized. Another objective was to correlate the radiologic findings of these patients with the clinical severity of BPD. STUDY DESIGN We correlated serial tracheal aspirates with radiographic findings from 183 infants whose birth weight was < or = 1250 gm. BPD severity was assessed by oxygen dependency at 36 weeks of postconceptional age (36 w PCA) and at the time of discharge. Two radiologists independently scored films taken at birth and 1, 7, 14, 21, 28, and 35 days of life. RESULTS Of the study population, 55% were male and 35% were black; 80% received surfactant and 69% received dexamethasone; 91% survived. GPC isolates from throat cultures were mainly Staphylococcus [corrected] epidermidis and Streptococcus haemolyticus. A superimposed GNB colonization was present in 37% of these infants. Most common isolates were Klebsiella pneumoniae, Enterobacter cloacae, and Escherichia coli. Sepsis caused by GPC developed in 16% of all patients; 7% had sepsis caused by GNB. Infants infected with GNB remained receiving oxygen at 36 w PCA and at the time of discharge twice as often as those noninfected. RADIOLOGIC FINDINGS: Hyperinflation, interstitial changes, and generalized or localized emphysema were prominent features throughout. Mean radiologic scores increased over time in a pattern similar among GPC, GNB, and U. urealyticum infected and noninfected infants. High radiologic scores were not predictive at any time of infants who needed supplemental oxygen at 28 days and at 36 w PCA. Infants infected with U. urealyticum were neither clinically nor radiologically different than noncolonized neonates. CONCLUSION GPC, GNB, and U. urealyticum airway colonization is not associated with particular radiographic changes at any time. GNB-infected infants had the most severe BPD course, and yet they were radiologically indistinguishable from the other patients. U. urealyticum colonization does not result in more clinically severe BPD or demonstrate a unique radiologic course.

Abstract
Helicobacter pylori is associated with gastritis, peptic ulcer disease, and gastric cancer. Since gastric cancer is common in Peru, eradication of H. pylori may help to reduce the occurrence of gastric cancer. This study involved three randomized trials to determine the efficacy of four different triple-drug therapy regimens. The most successful regimen was furazolidone combined with bismuth subsalicylate and amoxicillin, which eradicated infection in 82% of patients. Patients successfully treated were followed every 2-3 months to determine the recurrence rate of H. pylori infection. Of 105 patients with H. pylori eradication documented by pathology and culture, 52% (55) returned for follow-up endoscopy, and in 73% (40) of these 55 the infection recurred during the 8-month follow-up period. Thirty-five patients from whom H. pylori was eradicated and who were tested for antibodies to H. pylori remained consistently seropositive. Rapid recurrence of H. pylori infection after successful eradication suggests that measures other than antimicrobial therapy are needed to fight H. pylori in developing countries.

Abstract
We studied the function of four different monitoring probes used with the Satlite pulse oximeter (Datex, Helsinki). The aim was to evaluate ease of use and compare the function of the probes and their attachment methods in different locations (finger, toe, ear, thumb web, instep, wrist, and ankle). Two similar pulse wave oximeters were used in the study. To select the best signal we determined the absolute height of the plethysmographic waveform for each probe. Probes were compared on awake normal adult volunteers (N = 13), in anesthetized adult patients (N = 12), and in neonates weighting 500-1000 g (N = 8). In all the adult trials, the clip-on finger probe was used as a reference, and probes taped or clipped onto the finger provided adequate signal from the ear or from the thumb web, however. In the neonates, taped-on probes were most satisfactory.

Abstract
BACKGROUND Airway colonization with Gram-negative bacilli (GNB) and Gram-positive cocci (GPC) is common in mechanically ventilated neonates. Whether GNB are related to nosocomial bloodstream infection (BSI) and/or to the severity of bronchopulmonary dysplasia (BPD) is unknown. METHODS We prospectively examine this relationship using a cohort design. Data from 260 < or = 1250-g birth weight inborn infants (1991 to 1995) intubated > or = 2 weeks included 917 serial tracheal cultures and 583 blood cultures. The severity of BPD was assessed by duration of mechanical ventilation, oxygen dependency at 36 weeks of postconceptional age and the use of home oxygen supplementation. RESULTS After 2 weeks of ventilation, 80% of the infants were colonized with GPC (Staphylococus epidermidis and Staphylococcus haemolyticus in 90% of the cases). Superimposed on 36% of these infants was GNB airway colonization with Klebsiella pneumoniae (25%), Enterobacter cloacae (25%), Escherichia coli (25%), Pseudomonas aeruginosa (10%), Serratia marcescen (10%), Acinetobacter baumannii and Haemophilus influenzae (5%). Comparison between 174 GPC- and 86 GNB-colonized infants showed that demographics, birth weight, gestational age, perinatal risk factors and mortality were similar. Fifteen percent of GNB-colonized infants developed BSI caused by GNB and 14% developed BSI caused by GPC. No significant temporal relationship between airway colonization and BSI was noted. GNB infants were ventilated longer and required oxygen at 36 weeks of postconceptional age and home oxygen supplementation twice as often as infants colonized only with GPC. GNB colonization was a predictor of severe BPD after controlling for ventilation. Ureaplasma colonization occurred in 28% of GNB-colonized and 33% of noncolonized infants and was not a predictor of BPD severity. CONCLUSION GNB airway colonization creates a moderate risk for BSI. Antibiotic treatment does not regularly eradicate GNB. GNB airway colonization is associated with severe BPD, but further studies will be necessary before therapeutic efforts to eradicate GNB from the airways should be undertaken.

Abstract
In vitro studies of intestinal lactase activity and breath-hydrogen studies have suggested that the capacity for lactose digestion in preterm infants is less than the usual intake. To explore this question using an in vivo approach, we determined the fraction of dietary lactose hydrolyzed to glucose (and galactose) in 14 preterm infants with a gestational age of 26-31 wk at the time of birth but a postconceptional age of 31-37 wk at the time of study. The percentage of lactose digested was estimated after 6-h, primed, constant gastric infusions of [1-(13)C]glucose and D-[-1-(13)C]lactose on alternate days. A coefficient of lactose fermentation was derived from the rates of pulmonary excretion of hydrogen and carbon dioxide. Mean (+/- SD) lactose digestion was 79 +/- 26%. There was a significant inverse rank (r = -0.799, P < 0.01) and linear (r = -0.587, P < 0.05) correlation between this variable and postconceptional age. The percentage of lactose fermented averaged 35 +/- 27%.

Abstract
This paper describes the case of a patient who developed a pharyngotonsillitis and Ludwig's angina, and as a complication the most rare and grave mediastinitis, a descending necrotizing mediastinitis. The patient developed and adult respiratory distress syndrome secondary to mediastinal spread of a peritonsillar abscess. Only the combination of "aggressive" surgical and medical therapy resulted in survival of the patient. Important is the management of patients in Critical Care presenting complications associated with this illness.

Abstract
We developed a simple flow-through system for measuring the net rate of pulmonary excretion of CO2 (VCO2). Its components, connected in series by plastic tubing, are the following: plastic oxygen hood, suction flask used both as a mixing and sampling chamber, Brooks mass flow controller, and wall suction. Gas aliquots withdrawn from the sampling flask are analyzed for CO2 concentration in the laboratory. The system was validated by measuring over a 60-min period the evolution of CO2 from the reaction of sodium carbonate with phosphoric acid. In 9 trials, the mean recovery of CO2 was 99.8%. In 14 studies in 11 preterm infants, we evaluated the reproducibility of duplicate measurements of CO2 production on consecutive days; in 9 of the studies, the coefficient of variation was < 5%, but in other 5 studies, it ranged from 7.7 to 35.8%. We believe that this device might have both research and clinical applicability.

Abstract
Until now, compliance with home apnea monitoring (HAM) has been assessed by parental recall. The availability of monitors with electronic memory allows a more objective evaluation of HAM. Fourteen premature infants discharged home from the hospital and receiving theophylline and 15 infants not receiving medication were studied. Medical and birth records, parent questionnaires, and 1 month of electronically recorded data were analyzed. Birth weights of the infants ranged from 850 to 2400 gm and gestational age from 26 to 34 weeks. Of 26 parents who recalled never leaving their infants unmonitored, 70% missed at least one night, 30% three or more. During the first month, treated infants were left unmonitored 21% of the days and 9% of the nights, and untreated babies were unmonitored 32% of the days and 15% of the nights. Average daily HAM use was 18 hours for treated and 16 hours for untreated (p = 0.19). Two weeks after discharge, the decline in use for treated babies was 5% (day and night), whereas for untreated infants the decrease was 20% during the day and 15% at night. Lead-related alarms occurred with similar frequency (one to two times per day) in both groups. Non-lead-related alarms were somewhat more frequent for treated (four times per day) than for untreated infants (twice daily). Parents' perception of the likelihood of severe apnea at the time of discharge influenced HAM use. Little risk prompted 13 hr/day use and moderate risk 16 hr/day, whereas great perceived risk resulted in 18 hr/day of monitoring.(ABSTRACT TRUNCATED AT 250 WORDS)
